ABSTRACT

Dual-energy X-ray absorptiometry (DXA) is a well-established technology with an important and well-known role in measuring bone mineral density (BMD) for the purpose of determining fracture risk, diagnosing osteoporosis, and monitoring treatment efficacy. However, aside from the assessment of bone status, DXA is likely underutilized in the field of orthopedics, and most orthopedists may not be aware of the full capabilities of DXA, particularly with regard to total body scans and body composition assessment. For example, DXA would be a valuable tool for monitoring body composition after surgery where compensatory changes in the affected limb may lead to right-left asymmetry (eg, tracking lean mass change after knee surgery), rehabilitation regimens for athletes, congenital and metabolic disorders that affect the musculoskeletal system, or monitoring sarcopenia and frailty in the elderly. Furthermore, preoperative and postoperative regional scans can track BMD changes during healing or alert surgeons to impending problems such as loss of periprosthetic bone, which could lead to implant failure. This article discusses the capabilities of DXA and how this technology could be better used to the advantage of the attending orthopedist.

Dual-energy X-ray absorptiometry, abbreviated as “DXA,” (although usually abbreviated in older literature as “DEXA”) was first introduced in 1987 (Hologic QDR-1000 system, Hologic, Inc) and immediately made all previous forms of radiation-based bone mineral density (BMD) measurement systems obsolete.¹ Since then, there have been many generations of the technology, with the main US manufacturers in 2017 being Hologic, Inc. and GE Lunar. There are 2 forms of DXA, peripheral systems (which usually measure BMD only in the radius, finger bones, or calcaneus) and central systems (which measure the radius, proximal femur [“hip”], lumbar spine, total body, and custom sites). The general principle of how DXA works is based on the differential attenuation of photons by bone, fat, and lean mass.² The DXA technique uses a low- and high-energy X-ray beam produced by an X-ray tube. With the low-energy beam, attenuation by bone is greater than attenuation by soft tissue. With the high-energy beam, attenuation by bone and soft tissues are similar. The dual X-ray beams are passed through the body regions being scanned (usually posterioanteriorly), and the differential attenuation by bone and soft tissue is analyzed to produce BMD estimates. In addition, a high-quality image is produced to enable the operator of the DXA system to verify that the appropriate body region was scanned. It is important to realize that DXA is 2-dimensional (which is sometimes cited as a weakness of DXA), and the units of BMD are grams of mineral per centimeter squared (g/cm²).

Because of the nature of the scan mechanics and speed, the effective radiation dose with DXA is very low, expressed in microSieverts.^4,5 Generally, the radiation exposure from a series of the lumbar spine, proximal femur, and distal radius is about the same as daily background radiation. Even total body scans present very low exposure due to the scan speed at which any 1 body part is exposed for only a fraction of a second.

BENEFITS OF USING DXA FOR THE ORTHEOPEDIST

At the time of this writing in 2018, the presumption could be made that most physicians in the specialties of internal medicine, rheumatology, endocrinology, radiology, and orthopedics were familiar with the capabilities of DXA to assess BMD for the purpose of diagnosing osteoporosis. However, DXA is likely underused for other purposes, as orthopedists may be unaware of the full capabilities of DXA. Printouts after a scan contain more information than simply BMD, and there are more features and applications of DXA that can potentially be useful to orthopedists.

BONE SIZE

Data from a DXA scan are expressed not only as g/cm² (BMD) but also as total grams in the ROI (known as bone mineral content, abbreviated as BMC), and cm² (area of the ROI). These data may appear on a separate page, being considered ancillary results. The latter 2 variables are rarely included on a report sent to a referring physician; therefore, awareness of their value is probably limited. However, there are instances where such information could be valuable when interpreting results, especially bone size.^6,7 For example, on occasion, patients present with osteopenic lumbar vertebrate but larger than normal vertebral size (area). Many studies have shown that bone size is directly related to bone strength and thus fracture risk.^8,9 Although an understudied phenomenon, large vertebral body size could be protective, counteracting a lower than optimal BMD. Further, because the area of the ROI is measured, it is possible to calculate the bone width (or measure directly with a ruler tool in the software if available) for the area measured. This is especially feasible for tubular bones such as the midshaft of the radius, or more specifically, the classic DXA ROI being the area approximately one third the length of the radius from the distal end, the radius 33% region (actually based on ulna length). Consequently, it is possible to use the width of the radius 33% ROI in addition to BMD and T-score when assessing fracture risk.

CASE STUDY

A 60-year-old man had a DXA series of the lumbar spine, proximal femur, and whole body. His total body T-score was 0.6 (normal), and his total proximal femur T-score was −0.8 (normal), but his lumbar spine vertebrae 2 to 4 T-score was −1.9. As the patient was osteopenic based on the lumbar spine T-score, some physicians may have initiated antiresorptive therapy, especially if other risk factors for fracture were present. Further examination of the ancillary results of the DXA scan revealed that the vertebral body height T-score was a remarkable 1.11 and 1.53 after adjustment for stature (automatic software calculation). These results suggested that the patient had vertebral bodies of above average size, which theoretically would be protective against fracture even though the BMD T-score was below normal. For this patient, this finding mitigated immediate concern about the lumbar spine T-score of −1.9. Although vertebral body size is not typically used in assessing fracture risk, it is useful information that could be factored into the decision to start treatment or watch for further change with aging.

CASE SERIES: DISTAL RADIUS FRACTURES

Table 1 summarizes the data comparing radius 33% ROI T-scores and ROI width in patients who fractured the contralateral radius and normal nonfractured controls.¹⁰  

Table 1. Comparison of Radius Width at the 33% Region of Interest (ROI) and Bone Mineral Density T-Scores in Premenopausal Women With and Without Fractures

For premenopausal women with distal radius fractures, the width of the radius at the radius 33% ROI was significantly smaller than that in controls. However, there was no difference in T-scores between premenopausal women with distal radius fractures and controls. Thus, bone width more accurately identified women with fractures than T-scores based on BMD, and the orthopedist could use bone size in addition to BMD to predict fracture risk in a patient.

PREPARATION FOR SURGERY

For some procedures, there is potential benefit of assessing bone status prior to surgery. That is, determination of low BMD could potentially influence the type of hardware or fixation techniques used in surgery. Various studies have shown that poor bone quality and low BMD can impair purchase with various types of fixation.^11-13 Low preoperative BMD has been shown to be related to high implant migration.¹⁴ Knowledge of BMD could influence the choice of screw type used or the type of implant metal (titanium vs cobalt chrome). Another example is predicting the risk of spine curvature progression in adolescent idiopathic scoliosis.^15-17 It has been reported that low BMD is a risk factor for progression.¹⁵ Knowledge of BMD could potentially help with patient management strategies. For example, a patient with low BMD and vitamin D deficiency could be treated (vitamin D supplementation) prior to planning surgery in an effort to improve the low BMD.

PERIOPROSTHETIC BMD

It is possible to monitor changes in BMD around implants using the periprosthetic software application (this usually needs to be purchased separately from standard software that is installed with a system set-up). Dramatic loss of bone due to stress shielding after total hip arthroplasty (THA) can be a risk factor for implant migration or potentially outright failure of fixation or breakthrough. If bone loss occurs and is observed in the early stages, then antiresorptive treatment can be initiated to limit further loss.^18,19 (Figure 1) shows the image from a periprosthetic scan.

CASE REPORT

A 60-year-old, 215-lb man had a total hip replacement using a newly introduced cemented collared cobalt-chromium alloy femoral stem. A baseline periprosthetic DXA scan was performed 6 weeks postoperatively. Compared to baseline, the change in BMD in the Gruen zone 5 was −8.2%, +6.5%, +4.9%, and +9.46% at 3, 6, 12, and 24 months, respectively. In contrast, dramatic BMD loss was seen in Gruen zone 7 (calcar region): −33.2%, −40.8%, −37.1%, and −34.1% at 3, 6, 12, and 24 months, respectively. Similar findings in other patients led to discontinuation of use of this stem in favor of a collarless stem in which less BMD loss was seen in Gruen zone 7. Although additional technologist training is required and scans may not be reimbursable, for research purposes or for evaluating new component prototypes, the periprosthetic DXA scan capability can be useful.

Various other custom scans can be used to detect and quantify vertebral fractures (vertebral fracture assessment application), monitor healing of fractures by scanning through radiolucent cast materials, or for research purposes to assess BMD at unusual locations.^21-23 Other new innovations, such as the ability to perform full-length scans of the femoral shaft and to quantify focal thickening of the lateral cortex to identify beaking, an abnormality associated with atypical femur fracture after long-term bisphosphonate use, continue to expand the utility of DXA. Using standard software, cadaver bones can be scanned prior to biomechanical testing for a variety of purposes, such as ensuring proper matching specimens in test groups. It has been reported that the common practice of using contralateral bone specimens can lead to bias, as the BMD can be significantly different in right and left bones from the same individual.^9,24

TOTAL BODY BMD AND BODY COMPOSITION SCANS

Perhaps the least understood capability of DXA from our experience working with orthopedists is the ability to perform total body scans and to obtain not only total body and regional BMD but also body composition data, namely grams of lean and fat mass.²⁵ Soft tissue (no bone pixels) is partitioned into fat and lean body mass by a calibration procedure (lean mass = total soft tissue –fat mass). DXA has become the standard for body composition assessment given the ease of data acquisition (a total body scan takes only a few minutes), accuracy, and precision of measurements. Compared with other methods (eg, skinfold thickness, bioelectrical impedance, and underwater weighing), it is the only method that gives regional values for fat mass, lean mass, and BMC (this allows the ability to compare left vs right sides).^25-27 The ability to perform regional measurements cannot be overstated, as stable body weight belies potential changes with age and disease that relate to redistribution of fat and lean mass. It is not possible to identify, let alone track, such changes by measuring gross body weight on a scale or with BMI calculations. However, redistribution of fat and lean mass can be monitored in great detail using DXA. Figures 2 and 3 show the typical output from a DXA total body/body composition scan.

Total body scans with body composition analyses have many applications. For example, monitoring growth and development or treatment in patients with congenital deformity, metabolic bone disease, osteoporosis, and frailty; patients undergoing rehabilitation; and patients having surgery that could affect the use of a contralateral limb with potential hypertrophy or atrophy. Accurate assessment of percent body fat and fat distribution may help surgeons to improve risk stratification and surgical outcome.^28-30 Fracture risk has been associated with muscle area.²⁸ Simple measurements of quadriceps size underestimates atrophy, and total body composition can quantitate lean mass.³⁰

In sports medicine, body composition assessments could be useful to monitor postoperative recovery and effectiveness of rehabilitation protocols after injury, effectiveness of conditioning and training programs, developmental changes due to sports participation, and for obtaining baseline assessment at the time of preseason physicals.^27,31-34 In athletes, baseline status and morphological adaptations to training have traditionally been measured by anthropometry (eg, skinfold thickness, BMI, limb circumference, etc.), but DXA total body scanning allows for much more detailed assessments with the possibility of subregional quantitation. There is evidence for sports-specific body composition profiles and characteristic adaptations.^27,31-34 Using DXA, adaptive changes as a result of training as well as changes and recovery after surgery or injury can be monitored. For example, quadriceps atrophy usually occurs to some extent after ACL repair, and bone mineral loss and muscle atrophy occur after a limb has been immobilized with a cast. DXA body composition assessment could be used to monitor leg lean mass after surgery for comparison with presurgery values or those of the contralateral noninjured side, or to track recovery of bone mineral and muscle after a cast is removed. Some technical sports, such as tennis and baseball pitching, are known to result in limb asymmetry; DXA body composition could be used to monitor development of right-left arm asymmetry in tennis players or baseball pitchers, and then measures could be taken to balance the asymmetry. Wrestlers and elite dancers are expected to maintain strict weight requirements, but diets are often poor, and as such, DXA body composition could be used to track the effects of dieting and training by comparing serial measurements to baseline to ensure that weight changes include preservation or gain of muscle mass.³¹

Continue to: For older patients...

For older patients being followed after orthopedic care, there is a growing concern about age-related loss of muscle mass, or sarcopenia, which can lead to functional impairment (eg, balance, gait, etc.), and physical disability leading to falling and increased risk of fracture.^35-40 Even obese patients can be sarcopenic (a concept known as sarcopenic obesity), and their large body mass can mask the relative deficiency of lean mass.⁴⁰ DXA total body scans can be used to monitor patients at risk for sarcopenia.

Finally, DXA total body composition scans are underused in the pediatric population. Given the low radiation burden, DXA can be used safely in children of all ages. In addition to the same uses as in adults for presurgical assessment, monitoring bone and soft-tissue changes after treatment and rehabilitation, scans can be used to monitor growth and development.⁴¹

CASE STUDY: MONITORING DEVELOPMENT AND TREATMENT

A 12-year-old boy with polyostotic fibrous dysplasia (McCune Albright Syndrome) was started on treatment with cyclic pamidronate to mitigate bone pain and reduce fracture risk. Use of DXA was planned to provide evidence of treatment efficacy by documenting increasing BMD. However, the severe skeletal deformity prevented standard site-specific DXA scans, and consequently, total body scans were effectively used to acquire the BMD data needed to monitor treatment (Figure 4).

CASE STUDY: AGE-RELATED SARCOPENIA

Figure 5 shows images of a 64-year-old woman who was followed after a distal radius fracture. A total body scan and body composition assessment was performed in 2002. At follow-up in 2004, total body weight seemed stable with only a seemingly benign 5.1-lb loss of weight, and the patient’s overall physical appearance was unchanged (Table 2). 

Table 2. Age-Related Changes Potentially Leading to Sarcopenia

Dual-energy X-ray absorptiometry scans were performed using a GE Lunar Prodigy system.

However, body composition assessment revealed a disproportionate loss of lean mass, with a resultant total percent body fat increase. This imbalance between the change in fat and lean mass could lead to clinical sarcopenia unless appropriate dietary and exercise measures are taken. Such subtle developing imbalances in body composition could only be quantitated using DXA total body scans.

Continue to: It is not uncommon...

CASE STUDY: WEIGHT CHANGE IN A RECREATIONAL ATHLETE

It is not uncommon to encounter patients who have substantial weight changes as a result of lifestyle changes, such as dieting. It is also possible that body weight remains stable, but variable changes occur in the amount and distribution of fat and lean mass. Combining exercise with dieting is more likely to be associated with preservation or gain of lean mass. Such a case is presented. After a knee injury, a club tennis player reported gaining 30 lb in the subsequent 12 months. She enrolled in a DXA study, and serial body composition assessments were performed as she started a diet program and exercised on a treadmill and stationary bike. Table 3 shows body composition changes from baseline. 

Table 3. Body Composition Changes After Dieting and Exercise

Dual-energy X-ray absorptiometry scans were performed using a GE Lunar Prodigy system.

Although gross weight using a scale clearly showed progress in losing weight, it did not provide information about redistribution of fat and lean mass. The DXA body composition assessment showed that at follow up, there was a 22% decrease in total grams of fat and a 6% increase in lean mass (changes were uniform over different body regions). Her BMI still categorized her as being overweight; however, her body composition changes demonstrated that diet and exercise were producing positive results.

CONCLUSION

There are many ways in which DXA technology could provide orthopedists with valuable baseline and postoperative and post-treatment information about their patients. This technology could be used more effectively by orthopedists in both general clinical practice and research.

Dual-energy X-ray absorptiometry (DXA) is a well-established technology with an important and well-known role in measuring bone mineral density (BMD) for the purpose of determining fracture risk, diagnosing osteoporosis, and monitoring treatment efficacy. However, aside from the assessment of bone status, DXA is likely underutilized in the field of orthopedics, and most orthopedists may not be aware of the full capabilities of DXA, particularly with regard to total body scans and body composition assessment. For example, DXA would be a valuable tool for monitoring body composition after surgery where compensatory changes in the affected limb may lead to right-left asymmetry (eg, tracking lean mass change after knee surgery), rehabilitation regimens for athletes, congenital and metabolic disorders that affect the musculoskeletal system, or monitoring sarcopenia and frailty in the elderly. Furthermore, preoperative and postoperative regional scans can track BMD changes during healing or alert surgeons to impending problems such as loss of periprosthetic bone, which could lead to implant failure. This article discusses the capabilities of DXA and how this technology could be better used to the advantage of the attending orthopedist.

Dual-energy X-ray absorptiometry, abbreviated as “DXA,” (although usually abbreviated in older literature as “DEXA”) was first introduced in 1987 (Hologic QDR-1000 system, Hologic, Inc) and immediately made all previous forms of radiation-based bone mineral density (BMD) measurement systems obsolete.¹ Since then, there have been many generations of the technology, with the main US manufacturers in 2017 being Hologic, Inc. and GE Lunar. There are 2 forms of DXA, peripheral systems (which usually measure BMD only in the radius, finger bones, or calcaneus) and central systems (which measure the radius, proximal femur [“hip”], lumbar spine, total body, and custom sites). The general principle of how DXA works is based on the differential attenuation of photons by bone, fat, and lean mass.² The DXA technique uses a low- and high-energy X-ray beam produced by an X-ray tube. With the low-energy beam, attenuation by bone is greater than attenuation by soft tissue. With the high-energy beam, attenuation by bone and soft tissues are similar. The dual X-ray beams are passed through the body regions being scanned (usually posterioanteriorly), and the differential attenuation by bone and soft tissue is analyzed to produce BMD estimates. In addition, a high-quality image is produced to enable the operator of the DXA system to verify that the appropriate body region was scanned. It is important to realize that DXA is 2-dimensional (which is sometimes cited as a weakness of DXA), and the units of BMD are grams of mineral per centimeter squared (g/cm²).

Because of the nature of the scan mechanics and speed, the effective radiation dose with DXA is very low, expressed in microSieverts.^4,5 Generally, the radiation exposure from a series of the lumbar spine, proximal femur, and distal radius is about the same as daily background radiation. Even total body scans present very low exposure due to the scan speed at which any 1 body part is exposed for only a fraction of a second.

BENEFITS OF USING DXA FOR THE ORTHEOPEDIST

At the time of this writing in 2018, the presumption could be made that most physicians in the specialties of internal medicine, rheumatology, endocrinology, radiology, and orthopedics were familiar with the capabilities of DXA to assess BMD for the purpose of diagnosing osteoporosis. However, DXA is likely underused for other purposes, as orthopedists may be unaware of the full capabilities of DXA. Printouts after a scan contain more information than simply BMD, and there are more features and applications of DXA that can potentially be useful to orthopedists.

BONE SIZE

Data from a DXA scan are expressed not only as g/cm² (BMD) but also as total grams in the ROI (known as bone mineral content, abbreviated as BMC), and cm² (area of the ROI). These data may appear on a separate page, being considered ancillary results. The latter 2 variables are rarely included on a report sent to a referring physician; therefore, awareness of their value is probably limited. However, there are instances where such information could be valuable when interpreting results, especially bone size.^6,7 For example, on occasion, patients present with osteopenic lumbar vertebrate but larger than normal vertebral size (area). Many studies have shown that bone size is directly related to bone strength and thus fracture risk.^8,9 Although an understudied phenomenon, large vertebral body size could be protective, counteracting a lower than optimal BMD. Further, because the area of the ROI is measured, it is possible to calculate the bone width (or measure directly with a ruler tool in the software if available) for the area measured. This is especially feasible for tubular bones such as the midshaft of the radius, or more specifically, the classic DXA ROI being the area approximately one third the length of the radius from the distal end, the radius 33% region (actually based on ulna length). Consequently, it is possible to use the width of the radius 33% ROI in addition to BMD and T-score when assessing fracture risk.

CASE STUDY

A 60-year-old man had a DXA series of the lumbar spine, proximal femur, and whole body. His total body T-score was 0.6 (normal), and his total proximal femur T-score was −0.8 (normal), but his lumbar spine vertebrae 2 to 4 T-score was −1.9. As the patient was osteopenic based on the lumbar spine T-score, some physicians may have initiated antiresorptive therapy, especially if other risk factors for fracture were present. Further examination of the ancillary results of the DXA scan revealed that the vertebral body height T-score was a remarkable 1.11 and 1.53 after adjustment for stature (automatic software calculation). These results suggested that the patient had vertebral bodies of above average size, which theoretically would be protective against fracture even though the BMD T-score was below normal. For this patient, this finding mitigated immediate concern about the lumbar spine T-score of −1.9. Although vertebral body size is not typically used in assessing fracture risk, it is useful information that could be factored into the decision to start treatment or watch for further change with aging.

CASE SERIES: DISTAL RADIUS FRACTURES

Table 1 summarizes the data comparing radius 33% ROI T-scores and ROI width in patients who fractured the contralateral radius and normal nonfractured controls.¹⁰  

Table 1. Comparison of Radius Width at the 33% Region of Interest (ROI) and Bone Mineral Density T-Scores in Premenopausal Women With and Without Fractures

For premenopausal women with distal radius fractures, the width of the radius at the radius 33% ROI was significantly smaller than that in controls. However, there was no difference in T-scores between premenopausal women with distal radius fractures and controls. Thus, bone width more accurately identified women with fractures than T-scores based on BMD, and the orthopedist could use bone size in addition to BMD to predict fracture risk in a patient.

PREPARATION FOR SURGERY

For some procedures, there is potential benefit of assessing bone status prior to surgery. That is, determination of low BMD could potentially influence the type of hardware or fixation techniques used in surgery. Various studies have shown that poor bone quality and low BMD can impair purchase with various types of fixation.^11-13 Low preoperative BMD has been shown to be related to high implant migration.¹⁴ Knowledge of BMD could influence the choice of screw type used or the type of implant metal (titanium vs cobalt chrome). Another example is predicting the risk of spine curvature progression in adolescent idiopathic scoliosis.^15-17 It has been reported that low BMD is a risk factor for progression.¹⁵ Knowledge of BMD could potentially help with patient management strategies. For example, a patient with low BMD and vitamin D deficiency could be treated (vitamin D supplementation) prior to planning surgery in an effort to improve the low BMD.

PERIOPROSTHETIC BMD

It is possible to monitor changes in BMD around implants using the periprosthetic software application (this usually needs to be purchased separately from standard software that is installed with a system set-up). Dramatic loss of bone due to stress shielding after total hip arthroplasty (THA) can be a risk factor for implant migration or potentially outright failure of fixation or breakthrough. If bone loss occurs and is observed in the early stages, then antiresorptive treatment can be initiated to limit further loss.^18,19 (Figure 1) shows the image from a periprosthetic scan.

CASE REPORT

A 60-year-old, 215-lb man had a total hip replacement using a newly introduced cemented collared cobalt-chromium alloy femoral stem. A baseline periprosthetic DXA scan was performed 6 weeks postoperatively. Compared to baseline, the change in BMD in the Gruen zone 5 was −8.2%, +6.5%, +4.9%, and +9.46% at 3, 6, 12, and 24 months, respectively. In contrast, dramatic BMD loss was seen in Gruen zone 7 (calcar region): −33.2%, −40.8%, −37.1%, and −34.1% at 3, 6, 12, and 24 months, respectively. Similar findings in other patients led to discontinuation of use of this stem in favor of a collarless stem in which less BMD loss was seen in Gruen zone 7. Although additional technologist training is required and scans may not be reimbursable, for research purposes or for evaluating new component prototypes, the periprosthetic DXA scan capability can be useful.

Various other custom scans can be used to detect and quantify vertebral fractures (vertebral fracture assessment application), monitor healing of fractures by scanning through radiolucent cast materials, or for research purposes to assess BMD at unusual locations.^21-23 Other new innovations, such as the ability to perform full-length scans of the femoral shaft and to quantify focal thickening of the lateral cortex to identify beaking, an abnormality associated with atypical femur fracture after long-term bisphosphonate use, continue to expand the utility of DXA. Using standard software, cadaver bones can be scanned prior to biomechanical testing for a variety of purposes, such as ensuring proper matching specimens in test groups. It has been reported that the common practice of using contralateral bone specimens can lead to bias, as the BMD can be significantly different in right and left bones from the same individual.^9,24

TOTAL BODY BMD AND BODY COMPOSITION SCANS

Perhaps the least understood capability of DXA from our experience working with orthopedists is the ability to perform total body scans and to obtain not only total body and regional BMD but also body composition data, namely grams of lean and fat mass.²⁵ Soft tissue (no bone pixels) is partitioned into fat and lean body mass by a calibration procedure (lean mass = total soft tissue –fat mass). DXA has become the standard for body composition assessment given the ease of data acquisition (a total body scan takes only a few minutes), accuracy, and precision of measurements. Compared with other methods (eg, skinfold thickness, bioelectrical impedance, and underwater weighing), it is the only method that gives regional values for fat mass, lean mass, and BMC (this allows the ability to compare left vs right sides).^25-27 The ability to perform regional measurements cannot be overstated, as stable body weight belies potential changes with age and disease that relate to redistribution of fat and lean mass. It is not possible to identify, let alone track, such changes by measuring gross body weight on a scale or with BMI calculations. However, redistribution of fat and lean mass can be monitored in great detail using DXA. Figures 2 and 3 show the typical output from a DXA total body/body composition scan.

Total body scans with body composition analyses have many applications. For example, monitoring growth and development or treatment in patients with congenital deformity, metabolic bone disease, osteoporosis, and frailty; patients undergoing rehabilitation; and patients having surgery that could affect the use of a contralateral limb with potential hypertrophy or atrophy. Accurate assessment of percent body fat and fat distribution may help surgeons to improve risk stratification and surgical outcome.^28-30 Fracture risk has been associated with muscle area.²⁸ Simple measurements of quadriceps size underestimates atrophy, and total body composition can quantitate lean mass.³⁰

In sports medicine, body composition assessments could be useful to monitor postoperative recovery and effectiveness of rehabilitation protocols after injury, effectiveness of conditioning and training programs, developmental changes due to sports participation, and for obtaining baseline assessment at the time of preseason physicals.^27,31-34 In athletes, baseline status and morphological adaptations to training have traditionally been measured by anthropometry (eg, skinfold thickness, BMI, limb circumference, etc.), but DXA total body scanning allows for much more detailed assessments with the possibility of subregional quantitation. There is evidence for sports-specific body composition profiles and characteristic adaptations.^27,31-34 Using DXA, adaptive changes as a result of training as well as changes and recovery after surgery or injury can be monitored. For example, quadriceps atrophy usually occurs to some extent after ACL repair, and bone mineral loss and muscle atrophy occur after a limb has been immobilized with a cast. DXA body composition assessment could be used to monitor leg lean mass after surgery for comparison with presurgery values or those of the contralateral noninjured side, or to track recovery of bone mineral and muscle after a cast is removed. Some technical sports, such as tennis and baseball pitching, are known to result in limb asymmetry; DXA body composition could be used to monitor development of right-left arm asymmetry in tennis players or baseball pitchers, and then measures could be taken to balance the asymmetry. Wrestlers and elite dancers are expected to maintain strict weight requirements, but diets are often poor, and as such, DXA body composition could be used to track the effects of dieting and training by comparing serial measurements to baseline to ensure that weight changes include preservation or gain of muscle mass.³¹

Continue to: For older patients...

For older patients being followed after orthopedic care, there is a growing concern about age-related loss of muscle mass, or sarcopenia, which can lead to functional impairment (eg, balance, gait, etc.), and physical disability leading to falling and increased risk of fracture.^35-40 Even obese patients can be sarcopenic (a concept known as sarcopenic obesity), and their large body mass can mask the relative deficiency of lean mass.⁴⁰ DXA total body scans can be used to monitor patients at risk for sarcopenia.

Finally, DXA total body composition scans are underused in the pediatric population. Given the low radiation burden, DXA can be used safely in children of all ages. In addition to the same uses as in adults for presurgical assessment, monitoring bone and soft-tissue changes after treatment and rehabilitation, scans can be used to monitor growth and development.⁴¹

CASE STUDY: MONITORING DEVELOPMENT AND TREATMENT

A 12-year-old boy with polyostotic fibrous dysplasia (McCune Albright Syndrome) was started on treatment with cyclic pamidronate to mitigate bone pain and reduce fracture risk. Use of DXA was planned to provide evidence of treatment efficacy by documenting increasing BMD. However, the severe skeletal deformity prevented standard site-specific DXA scans, and consequently, total body scans were effectively used to acquire the BMD data needed to monitor treatment (Figure 4).

CASE STUDY: AGE-RELATED SARCOPENIA

Figure 5 shows images of a 64-year-old woman who was followed after a distal radius fracture. A total body scan and body composition assessment was performed in 2002. At follow-up in 2004, total body weight seemed stable with only a seemingly benign 5.1-lb loss of weight, and the patient’s overall physical appearance was unchanged (Table 2). 

Table 2. Age-Related Changes Potentially Leading to Sarcopenia

Dual-energy X-ray absorptiometry scans were performed using a GE Lunar Prodigy system.

However, body composition assessment revealed a disproportionate loss of lean mass, with a resultant total percent body fat increase. This imbalance between the change in fat and lean mass could lead to clinical sarcopenia unless appropriate dietary and exercise measures are taken. Such subtle developing imbalances in body composition could only be quantitated using DXA total body scans.

Continue to: It is not uncommon...

CASE STUDY: WEIGHT CHANGE IN A RECREATIONAL ATHLETE

It is not uncommon to encounter patients who have substantial weight changes as a result of lifestyle changes, such as dieting. It is also possible that body weight remains stable, but variable changes occur in the amount and distribution of fat and lean mass. Combining exercise with dieting is more likely to be associated with preservation or gain of lean mass. Such a case is presented. After a knee injury, a club tennis player reported gaining 30 lb in the subsequent 12 months. She enrolled in a DXA study, and serial body composition assessments were performed as she started a diet program and exercised on a treadmill and stationary bike. Table 3 shows body composition changes from baseline. 

Table 3. Body Composition Changes After Dieting and Exercise

Dual-energy X-ray absorptiometry scans were performed using a GE Lunar Prodigy system.

Although gross weight using a scale clearly showed progress in losing weight, it did not provide information about redistribution of fat and lean mass. The DXA body composition assessment showed that at follow up, there was a 22% decrease in total grams of fat and a 6% increase in lean mass (changes were uniform over different body regions). Her BMI still categorized her as being overweight; however, her body composition changes demonstrated that diet and exercise were producing positive results.

CONCLUSION

There are many ways in which DXA technology could provide orthopedists with valuable baseline and postoperative and post-treatment information about their patients. This technology could be used more effectively by orthopedists in both general clinical practice and research.

The emphasis on cultural context of diagnosis and treatment of psychiatric disorders was expanded in the DSM-5, but the commonly used term for this orientation, “cultural competence,” is potentially misleading, according to a panel of experienced clinicians participating in a workshop at the annual meeting of the American Psychiatric Association.

“I am not even sure how competent I am in my own culture,” said Richa Bhatia, MD, medical director of the Child and Adolescent OCD Institute at McLean Hospital, Belmont, Mass.. The remark was representative; like other panelists in a workshop developed by the Association of Women Psychiatrists, she de-emphasized the importance of becoming fluent in the specifics of a culture relative to simply being sensitive to variations in cultural landmarks and milestones.

Ted Bosworth/MDedge News

Familiarity with cultural milestones can be reassuring to patients, but Sherry P. Katz-Bearnot, MD, assistant clinical professor of psychiatry at Columbia University, cautioned that there is counterproductive underside to cultural competence. While recognizing the significance of cultural milestones, such as a bar mitvah or quinceañera, can be reassuring to patients, Dr. Katz-Bearnot emphasized that clinicians must remain sensitive to the personal responses to those events.

“If you know too much, there is a risk of glossing over the issues unique to the individual in front of you,” Dr. Katz-Bearnot said. She emphasized that those cultural landmarks do not necessarily mean the same thing to all members of a community. Sensitivity to personal issues trumps cultural familiarity.

The same statement could be made for delivering care to transgender patients, judging from a presentation by Courtney Saw, MD, a PGY3 resident in the department of psychiatry at the University of Pennsylvania, Philadelphia. Quoting a survey that found most transgender individuals consider health care professionals inadequately trained to manage their health issues, she stressed the importance of how questions are phrased.

“Every patient’s gender journey is unique,” Dr. Saw said. For example, specific questions about gender anatomy should be supplanted by open questions about gender transition, allowing patients to respond at their own level of comfort. This, according to Dr. Saw, is essential for “building a therapeutic collaboration.”

Embracing the concept of cultural humility, all of the panelists agreed that it is far less important to have cultural expertise than it is to be open, curious, and accepting. Sensitivity is more important than competence when specific cultural issues are relevant to treatment.

“We don’t have to have all the answers. We just need to be good at listening so that we can help patients work their way towards the answers,” Dr. Saw suggested. Others agreed.

Dr. Bhatia, Dr. Olarte, Dr. Dominguez, Dr. Katz-Bearnot, and Dr. Saw reported no potential conflicts of interest related to this topic.

While some investigations have suggested that depression may lead to later unfavorable effects on heart rate variability, authors of a newly published study say they have found stronger evidence that the opposite is true.

Lower heart rate variability was independently associated with later increases in depressive symptoms, according to results of the longitudinal, twin difference study.

When researchers looked at the opposite direction, they found earlier depressive symptoms were associated with lower heart rate variability at follow-up in the study; however, investigators said those associations were not as robust and were largely explainable by antidepressant use.

That meant reduced heart rate variability is more likely a risk factor for depression, rather than a consequence, according to Minxuan Huang, ScM, of the department of epidemiology at Emory University Rollins School of Public Health, Atlanta, and his coinvestigators.

“These findings point to a central role of the autonomic nervous system in the regulation of mood and depression vulnerability,” they wrote in a report on the study appearing in JAMA Psychiatry.

The published analysis included 146 male twins, or 73 pairs, who participated in the national Vietnam Era Twin Registry.

Previous studies have linked depression to heart rate variability, a noninvasive index of cardiac autonomic nervous system regulation. However, these studies are not consistent on whether depression affects heart rate variability or vice versa, and the studies have been limited in their ability to assess the relationship between those two variables over time, the investigators said.

By contrast, the current study evaluated depression and heart rate variability at two time points: a baseline assessment conducted during 2002-2006 and a at a 7-year follow-up visit.

Investigators found consistent associations between heart rate variability on 24-hour electrocardiogram monitoring at baseline and scores on the Beck Depression Inventory-II at the 7-year follow-up, with beta coefficients ranging from –0.14 to –0.29, the report showed.

By contrast, the associations were less consistent between BDI-II score at the baseline visit and heart rate variability at follow-up, the investigators said. “These associations were largely explained by antidepressant use, which when added to the model, weakened the associations.”

These findings may help guide future research aimed at identifying individuals at a higher risk of later depression, the authors said, noting that treatment studies also are warranted. “Future interventions modulating autonomic nervous system regulation may be useful for the prevention and treatment of depression.” The study was supported by the National Institutes of Health. The Department of Veterans Affairs has supported the Vietnam Era Twin Registry. The researchers had no conflicts of interest.

Darrin Klimek/Thinkstock

Like everyone in the arc of social media impact, I was shocked and terribly saddened by the recent suicides of two New York women in medicine – a final-year medical student on May 1 and a second-year resident on May 5. As a specialist in physician health, a former training director, a long-standing member of our institution’s medical student admissions committee, and the ombudsman for our medical students, I am finding these tragedies harder and harder to reconcile. Something isn’t working. But before I get to that, what follows is a bulleted list of some events of the past couple of weeks that may give a context for my statements and have informed my two recommendations.

• May 3, 2018: I give an invited GI grand rounds on stress, burnout, depression, and suicide in physicians. The residents are quiet and say nothing. Faculty members seem only concerned about preventing and eradicating burnout – and not that interested in anything more severe.
• May 5: A psychiatry resident from Melbourne arrives to spend 10 days with me to do an elective in physician health. As in the United States, there is a significant suicide death rate in medical students and residents Down Under. In the afternoon, I present a paper at the annual meeting of the American Academy of Psychodynamic Psychiatry and Psychoanalysis on the use of psychotherapy in treatment-resistant suicidal depression in physicians. There is increasing hope that this essential modality of care will return to the contemporary psychiatrist’s toolbox.
• May 6: At the annual meeting of the American Psychiatric Association in New York, I’m the discussant for powerful heartfelt papers of five psychiatrists (mostly early career psychiatrists and one resident) that talked about living with a psychiatric illness. The audience is huge, and we hear narratives about internal stigma, self-disclosure, external stigma, shunning, bullying, acceptance, rejection, alienation, connection, and love by peers and family. The authenticity and valor of the speakers create an atmosphere of safety, which enables psychiatrists in attendance from all over the world to share their personal stories – some at the microphone, some privately.
• May 7: Again at the APA, I chair and facilitate a workshop on physician suicide. We hear from four speakers, all women, who have lost a loved one to suicide – a husband, a father, a brother, a son – all doctors. Two of the speakers are psychiatrists. The stories are gripping, detailed, and tender. Yes, the atmosphere is very sad, but there is not a pall. We learn how these doctors lived, not just how they died. They all loved medicine; they were creative; they cared deeply; they suffered silently; and with shame, they lost hope. Again, a big audience of psychiatrists, many of whom share their own stories, that they, too, had lost a physician son, wife, or mother to suicide. Some of their deceased family members fell through the cracks and did not receive the life-saving care they deserved; some, fearing assaults to their medical license, hospital privileges, or insurance, refused to see anyone. They died untreated.
• May 8: Still at the APA, a psychiatrist colleague and I collaborate on a clinical case conference. Each of us describes losing a physician patient to suicide. We walk the attendees through the clinical details of assessment, treatment, and the aftermath of their deaths. We talk openly and frankly about our feelings, grief, outreach to colleagues and the family, and our own personal journeys of learning, growth, and healing. The clinician audience members give constructive feedback, and some share their own stories of losing patients to suicide. Like the day before, some psychiatrists are grieving the loss of a physician son or sibling to suicide. As mental health professionals, they suffer from an additional layer of failure and guilt that a loved one died “under their watch.”
• May 8: I rush across the Javits Center to catch the discussant for a concurrent symposium on physician burnout and depression. She foregoes any prepared remarks to share her previous 48 hours with the audience. She is the training director of the program that lost the second-year resident on May 5. She did not learn of the death until 24 hours later. We are all on the edge of our seats as we listen to this grieving, courageous woman, a seasoned psychiatrist and educator, who has been blindsided by this tragedy. She has not slept. She called all of her residents and broke the news personally as best she could. Aided by “After A Suicide: A Toolkit for Residency/Fellowship Programs” (American Foundation for Suicide Prevention), she and her colleagues instituted a plan of action and worked with administration and faculty. Her strength and commitment to the well-being of her trainees is palpable and magnanimous. When the session ends, many of us stand in line to give her a hug. It is a stark reminder of how many lives are affected when someone you know or care about takes his/her own life – and how, in the house of medicine, medical students and residents really are part of an institutional family.
• May 10: I facilitate a meeting of our 12 second-year residents, many of whom knew of or had met the resident who died. Almost everyone speaks, shares their feelings, poses questions, and calls for answers and change. There is disbelief, sadness, confusion, some guilt, and lots of anger. Also a feeling of disillusionment or paradox about the field of psychiatry: “Of all branches of medicine, shouldn’t residents who are struggling with psychiatric issues feel safe, protected, cared for in psychiatry?” There is also a feeling of lip service being paid to personal treatment, as in quoted statements: “By all means, get treatment for your issues, but don’t let it encroach on your duty hours” or “It’s good you’re getting help, but do you still have to go weekly?”

In the immediate aftermath of suicide, feelings run high, as they should. But rather than wait it out – and fearing a return to “business as usual” – let me make only two suggestions:

Like everyone in the arc of social media impact, I was shocked and terribly saddened by the recent suicides of two New York women in medicine – a final-year medical student on May 1 and a second-year resident on May 5. As a specialist in physician health, a former training director, a long-standing member of our institution’s medical student admissions committee, and the ombudsman for our medical students, I am finding these tragedies harder and harder to reconcile. Something isn’t working. But before I get to that, what follows is a bulleted list of some events of the past couple of weeks that may give a context for my statements and have informed my two recommendations.

• May 3, 2018: I give an invited GI grand rounds on stress, burnout, depression, and suicide in physicians. The residents are quiet and say nothing. Faculty members seem only concerned about preventing and eradicating burnout – and not that interested in anything more severe.
• May 5: A psychiatry resident from Melbourne arrives to spend 10 days with me to do an elective in physician health. As in the United States, there is a significant suicide death rate in medical students and residents Down Under. In the afternoon, I present a paper at the annual meeting of the American Academy of Psychodynamic Psychiatry and Psychoanalysis on the use of psychotherapy in treatment-resistant suicidal depression in physicians. There is increasing hope that this essential modality of care will return to the contemporary psychiatrist’s toolbox.

Patients presenting to the ED with injuries due to accidental self-injection with an epinephrine pen typically receive treatment to alleviate symptoms and reduce the potential of digital ischemia leading to gangrene and loss of tissue and function. Although there is no consensus or set guidelines in the literature regarding the management protocol of such cases, many reports support pharmacological intervention. There are, however, other reports that advocate conservative, nonpharmaceutical management (eg, immersing the affected digit in warm water) or an observation-only approach.

We present the first case report in Saudi Arabia of digital ischemia due to accidental injection of an epinephrine autoinjector, along with a review of the literature and management recommendations.

Case

A 28-year-old woman presented to the ED in significant pain and discomfort 20 minutes after she accidentally injected the entire contents of her aunt’s epinephrine autoinjector (0.3 mg of 1:1000) into her right thumb. The patient, who was in significant pain and discomfort, stated that she was unable to remove the injector needle, which was firmly embedded in the bone of the palmer aspect of the distal phalanx in a manner similar to that of an intraosseous injection (Figure 1).

The patient’s vital signs and oxygen saturation on presentation were within normal limits. The emergency physician successfully removed the embedded needle through moderate countertraction. On examination, the patient’s right thumb was pale and cold, and had poor capillary refill (Figure 2). Due to concerns of the potential for digital tissue ischemia leading to tissue loss and gangrene, warm, moist compresses were applied to the affected thumb, followed by 2% topical nitroglycerin paste, after which the thumb was covered with an occlusive dressing. Since there was no improvement in circulation after 20 minutes, an infiltrate of 5 mg (0.5 mL of 10 mg/mL) of phentolamine (α-agonist) mixed with 2.5 mL of 2% lidocaine was injected at the puncture site and base of the right thumb.¹ Hyperemia developed immediately at both injection sites, and the patient’s right thumb returned to a normal color and sensation 1 hour later, with a return to normal capillary refill. She remained in stable condition and was discharged home. Prior to discharge, the patient was educated on the proper handling and administration of an epinephrine autoinjector.

Discussion

Epinephrine is an ὰ- and β-adrenergic agonist that binds to the ὰ-adrenergic receptors of blood vessels, causing an increase in vascular resistance and vasoconstriction. Although the plasma half-life of epinephrine is approximately 2 to 3 minutes, subcutaneous or intramuscular injection resulting in local vasoconstriction may delay absorption; therefore, the effects of epinephrine may last much longer than its half-life.

The incidence of accidental injection from an epinephrine autoinjector is estimated to be 1 per 50,000 units dispensed.² To date, there are no established treatment guidelines on managing cases of digital injection. An online PubMed and Google Scholar search of the literature found one systematic review,³ four observational studies,^4-7 seven case series,^8-14 and several case reports^1,15-33 on the subject. Most of the patients in the published retrospective studies (71%) were treated conservatively with warming of the affected hand and observation, and the majority of patients in the case reports (87%) were treated pharmacologically, most commonly with topical nitroglycerin and phentolamine.^1,3-34 All of the patients in both the retrospective studies and case reports had restoration of perfusion without necrosis, irrespective of treatment modality. However, patients who were managed conservatively or who were treated with topical nitroglycerin required a longer duration of stay in the ED, suffered from severe reperfusion pain, and in some cases, had a longer time to complete recovery (≥10 weeks).⁸

Pharmaceutical and Nonpharmaceutical Management

Phentolamine. Phentolamine is a nonselective ὰ-adrenergic antagonist that binds to ὰ1 and ὰ2 receptors of blood vessels, resulting in a decrease in peripheral vascular resistance and vasodilation. Phentolamine directly antagonizes the effect of epinephrine by blocking the ὰ-adrenergic receptors, which in our patient resulted in immediate return of digital circulation and full resolution of symptoms.

Topical Nitroglycerin. Nitroglycerin is a nitrate vasodilator that when metabolically converted to nitric oxide, results in smooth muscle relaxation, venodilation, and arteriodilation. Patients suffering from digital ischemia and vasoconstriction may be treated with topical nitroglycerin paste to reverse ischemia by causing smooth muscle relaxation of digital blood vessels. Conservative Management. As previously noted, not all cases of digital epinephrine injection are treated pharmacologically. Some patients are not treated, but kept in observation until the ischemic effects of epinephrine have resolved. Likewise, some patients are treated conservatively with warm water compresses or by fully immersing the affected digit in warm water to facilitate reversal of vasoconstriction and ischemia.^3,8

Treatment Efficacy

In 2007, Fitzcharles-Bowe et al⁸ published a review of 59 cases of digital injection with high-dose epinephrine from 1989 to 2005. In this review, 32 of the 59 patients received no treatment, 25 patients received pharmacological treatment and in two patients, the treatment was unknown. Phentolamine was the most commonly used pharmacological agent (15 of 25 cases or 60%). Although none of the patients experienced digital necrosis, those treated with a local infiltration of phentolamine experienced a faster resolution of symptoms and normalization of perfusion. In 2004, Turner¹ reported a case of a 10-year-old boy who was treated with phentolamine following an accidental injection of epinephrine into his left hand. While circulation returned to the affected digit within 5 minutes of receiving the phentolamine injection, the patient continued to experience reduced sensation in the digit 6 weeks later.⁸

Interestingly, one of the coauthors of the Fitzcharles-Bowe et al⁸ report intentionally injected three of the digits of his left hand (middle, ring, and small fingers) at the same time with high-dose epinephrine to carefully observe and document the outcomes. All three of the digits became very pale and cool, with decreased sensation. The author treated himself conservatively (observation-only). He experienced spontaneous return of circulation in two of the digits within 6 to 10 hours. Although there was some spontaneous return of circulation to the third digit after 13 hours, the author noted prolonged, intense reperfusion pain 4 hours after return of circulation. He also suffered from neuropraxia in the third digit, which did not fully resolve until 10 weeks after the injury.⁸

A review of the literature shows phentolamine to be a safe and effective treatment for patients presenting with digital ischemia, with no long-term adverse effects or complications. Moreover, phentolamine appears to be safe and effective for use in both adult and pediatric patients.^3,8,35-38

Accidental Injection Prevention

Some of the cases of accidental epinephrine injection are due to user error. For example, a novice user may be holding the incorrect end of the injector in his or her hand when attempting to administer/deploy the device, resulting in premature dislodgement of the needle.³⁹

Although, most of the autoinjector devices available today are user-friendly, we believe the addition of a safety feature such as a trigger or safety-lock may further help to reduce accidents. The European Medicines Agency recommends that all patients and caregivers receive training on the proper handling and administration of epinephrine autoinjectors, citing this as the most important factor to ensure successful use of an epinephrine autoinjector and reduce accidental injury.⁴⁰ The patient in this case had not received any formal education or training regarding autoinjector use prior to this incident.

Safety of Lidocaine-Containing Epinephrine in Digital Anesthesia

Aside from cases of accidental digital epinephrine injection, clinicians have traditionally been taught to avoid using lidocaine with epinephrine for digital anesthesia. However, since the introduction of commercial lidocaine with epinephrine in 1948, there are no case reports of digital gangrene from commercially available lidocaine-epinephrine formulations.^41,42 In a multicenter prospective study by Lalonde et al⁴³ of 3,110 consecutive cases of elective injection of low-dose epinephrine in the hand, the authors concluded the likelihood of finger infarction is remote, particularly with possible phentolamine rescue therapy. Moreover, lidocaine-containing epinephrine (1%-2%) has a much lower concentration of epinephrine per mL of solution (5-10 mcg/mL) and appears to be safe for digital use.

Conclusion

This case describes the presentation and treatment of accidental digital injection of epinephrine, highlighting and supporting the benefits of local infiltration with phentolamine and observation until full recovery of perfusion. Local treatment with phentolamine not only facilitates recovery and return of capillary refill, but also shortens the duration of symptoms and alleviates vasoconstriction. In less severe cases, watchful waiting and observation may be appropriate and effective.

This case also underscores the importance of patient and caregiver education on the proper handling and administration of epinephrine autoinjectors to decrease the incidence of accidental injection.

On examination, the patient’s right thumb was pale and cold, and had poor capillary refill (Figure 2). Due to concerns of the potential for digital tissue ischemia leading to tissue loss and gangrene, warm, moist compresses were applied to the affected thumb, followed by 2% topical nitroglycerin paste, after which the thumb was covered with an occlusive dressing. Since there was no improvement in circulation after 20 minutes, an infiltrate of 5 mg (0.5 mL of 10 mg/mL) of phentolamine (α-agonist) mixed with 2.5 mL of 2% lidocaine was injected at the puncture site and base of the right thumb.¹ Hyperemia developed immediately at both injection sites, and the patient’s right thumb returned to a normal color and sensation 1 hour later, with a return to normal capillary refill. She remained in stable condition and was discharged home. Prior to discharge, the patient was educated on the proper handling and administration of an epinephrine autoinjector.

Discussion

Epinephrine is an ὰ- and β-adrenergic agonist that binds to the ὰ-adrenergic receptors of blood vessels, causing an increase in vascular resistance and vasoconstriction. Although the plasma half-life of epinephrine is approximately 2 to 3 minutes, subcutaneous or intramuscular injection resulting in local vasoconstriction may delay absorption; therefore, the effects of epinephrine may last much longer than its half-life.

The incidence of accidental injection from an epinephrine autoinjector is estimated to be 1 per 50,000 units dispensed.² To date, there are no established treatment guidelines on managing cases of digital injection. An online PubMed and Google Scholar search of the literature found one systematic review,³ four observational studies,^4-7 seven case series,^8-14 and several case reports^1,15-33 on the subject. Most of the patients in the published retrospective studies (71%) were treated conservatively with warming of the affected hand and observation, and the majority of patients in the case reports (87%) were treated pharmacologically, most commonly with topical nitroglycerin and phentolamine.^1,3-34 All of the patients in both the retrospective studies and case reports had restoration of perfusion without necrosis, irrespective of treatment modality. However, patients who were managed conservatively or who were treated with topical nitroglycerin required a longer duration of stay in the ED, suffered from severe reperfusion pain, and in some cases, had a longer time to complete recovery (≥10 weeks).⁸

Pharmaceutical and Nonpharmaceutical Management

Phentolamine. Phentolamine is a nonselective ὰ-adrenergic antagonist that binds to ὰ1 and ὰ2 receptors of blood vessels, resulting in a decrease in peripheral vascular resistance and vasodilation. Phentolamine directly antagonizes the effect of epinephrine by blocking the ὰ-adrenergic receptors, which in our patient resulted in immediate return of digital circulation and full resolution of symptoms.

Topical Nitroglycerin. Nitroglycerin is a nitrate vasodilator that when metabolically converted to nitric oxide, results in smooth muscle relaxation, venodilation, and arteriodilation. Patients suffering from digital ischemia and vasoconstriction may be treated with topical nitroglycerin paste to reverse ischemia by causing smooth muscle relaxation of digital blood vessels. Conservative Management. As previously noted, not all cases of digital epinephrine injection are treated pharmacologically. Some patients are not treated, but kept in observation until the ischemic effects of epinephrine have resolved. Likewise, some patients are treated conservatively with warm water compresses or by fully immersing the affected digit in warm water to facilitate reversal of vasoconstriction and ischemia.^3,8

Treatment Efficacy

In 2007, Fitzcharles-Bowe et al⁸ published a review of 59 cases of digital injection with high-dose epinephrine from 1989 to 2005. In this review, 32 of the 59 patients received no treatment, 25 patients received pharmacological treatment and in two patients, the treatment was unknown. Phentolamine was the most commonly used pharmacological agent (15 of 25 cases or 60%). Although none of the patients experienced digital necrosis, those treated with a local infiltration of phentolamine experienced a faster resolution of symptoms and normalization of perfusion. In 2004, Turner¹ reported a case of a 10-year-old boy who was treated with phentolamine following an accidental injection of epinephrine into his left hand. While circulation returned to the affected digit within 5 minutes of receiving the phentolamine injection, the patient continued to experience reduced sensation in the digit 6 weeks later.⁸

Interestingly, one of the coauthors of the Fitzcharles-Bowe et al⁸ report intentionally injected three of the digits of his left hand (middle, ring, and small fingers) at the same time with high-dose epinephrine to carefully observe and document the outcomes. All three of the digits became very pale and cool, with decreased sensation. The author treated himself conservatively (observation-only). He experienced spontaneous return of circulation in two of the digits within 6 to 10 hours. Although there was some spontaneous return of circulation to the third digit after 13 hours, the author noted prolonged, intense reperfusion pain 4 hours after return of circulation. He also suffered from neuropraxia in the third digit, which did not fully resolve until 10 weeks after the injury.⁸

A review of the literature shows phentolamine to be a safe and effective treatment for patients presenting with digital ischemia, with no long-term adverse effects or complications. Moreover, phentolamine appears to be safe and effective for use in both adult and pediatric patients.^3,8,35-38

Accidental Injection Prevention

Some of the cases of accidental epinephrine injection are due to user error. For example, a novice user may be holding the incorrect end of the injector in his or her hand when attempting to administer/deploy the device, resulting in premature dislodgement of the needle.³⁹

Although, most of the autoinjector devices available today are user-friendly, we believe the addition of a safety feature such as a trigger or safety-lock may further help to reduce accidents. The European Medicines Agency recommends that all patients and caregivers receive training on the proper handling and administration of epinephrine autoinjectors, citing this as the most important factor to ensure successful use of an epinephrine autoinjector and reduce accidental injury.⁴⁰ The patient in this case had not received any formal education or training regarding autoinjector use prior to this incident.

Safety of Lidocaine-Containing Epinephrine in Digital Anesthesia

Aside from cases of accidental digital epinephrine injection, clinicians have traditionally been taught to avoid using lidocaine with epinephrine for digital anesthesia. However, since the introduction of commercial lidocaine with epinephrine in 1948, there are no case reports of digital gangrene from commercially available lidocaine-epinephrine formulations.^41,42 In a multicenter prospective study by Lalonde et al⁴³ of 3,110 consecutive cases of elective injection of low-dose epinephrine in the hand, the authors concluded the likelihood of finger infarction is remote, particularly with possible phentolamine rescue therapy. Moreover, lidocaine-containing epinephrine (1%-2%) has a much lower concentration of epinephrine per mL of solution (5-10 mcg/mL) and appears to be safe for digital use.

Conclusion

This case describes the presentation and treatment of accidental digital injection of epinephrine, highlighting and supporting the benefits of local infiltration with phentolamine and observation until full recovery of perfusion. Local treatment with phentolamine not only facilitates recovery and return of capillary refill, but also shortens the duration of symptoms and alleviates vasoconstriction. In less severe cases, watchful waiting and observation may be appropriate and effective.

This case also underscores the importance of patient and caregiver education on the proper handling and administration of epinephrine autoinjectors to decrease the incidence of accidental injection.

NEW YORK – For elderly individuals with depression exacerbated by physical limitations and personal losses, cognitive-behavioral therapy is a powerful tool for improving quality of life, according to the faculty of a workshop on this topic at the annual meeting of the American Psychiatric Association.

“The focus is on coping skills. It is about how to persevere in the face of adversity,” explained David A. Casey, MD, professor and chair of the department of psychiatry and behavioral sciences at University of Louisville (Ky.).

“Some patients are essentially immobilized by their withdrawal and convinced that their problems are unsolvable, but most will improve their quality of life through CBT,” he maintained.

There are data to support this contention, according to Jesse H. Wright III, MD, PhD, director of the Depression Center at the University of Louisville. He cited controlled studies demonstrating the efficacy of CBT relative to no CBT in relieving depression in the elderly.

“The evidence suggests that combining CBT with pharmacotherapy is better than either alone for managing depression in this age group,” Dr. Wright said.

In developing a therapeutic plan through CBT, patients are given assignments designed to develop participation in meaningful activities. These must be realistic within physical limitations and within the patient’s readiness to engage. Small steps toward a goal might be needed. At each therapeutic encounter, goals are set, and progress should be evaluated at the subsequent therapeutic encounter.

“A written plan is necessary. If you do not write it down, it probably will not happen,” Dr. Casey cautioned. He said a rehearsal of the actions needed to achieve the assigned goals might be helpful before the patient leaves the treatment session. This allows the clinician to recognize and address potential obstacles, including practical issues, such as mobility, or psychological issues, such as fear of physical activities.

Developing persistence in the face of high levels of negativity can be a challenge not only for the patient but also for the physician. According to Dr. Casey, maintaining a positive attitude can be challenging after treating a series of highly withdrawn and discouraged patients. But he emphasized the need for a professional orientation, recognizing that incremental gains in patient well-being, not cure, should be considered a reasonable goal.

“If I can improve the patient’s quality of life, this is a significant success,” he said. He believes it is sometimes necessary to distract patients from potential problems to focus on expected benefits.

“Patients can have a view of their limitations that is accurate but unhelpful,” Dr. Casey said. The goal of CBT is to move the focus to strategies that can restore lost interest and pleasure in daily life.

Dr. Casey and Dr. Wright reported no potential conflicts of interest related to this topic.

Poor sleep is associated with increased suicidal behaviors in college students – even when controlling for depression, a study of 1,700 students shows.

“Furthermore, findings suggest that some specific sleep components – shorter sleep duration, more frequent bad dreams, feeling too cold while sleeping, and greater sleep medication use – are particularly associated with increased suicidal behaviors in college students,” reported Stephen P. Becker, PhD, of the Cincinnati Children’s Hospital Center, and his associates.

The researchers recruited students from two universities. Most of the students (65%) were female, white (82%), and in their first year of college (63%). The participants’ sleep was assessed using the nine-item Pittsburgh Sleep Quality Index (PSQI), their depressive symptoms were assessed using the Depressive Anxiety Stress Scales-21, and their suicidal behavior was assessed using the Suicidal Behaviors Questionnaire-Revised (SBQ-R), which is a four-item, self-report measure.

About two-thirds of the students (64%) were found to have sleep problems (total PSQI score greater than 5), and 24% were found to have suicide risk (total SBQ-R score of at least 7). Of the students who were found to have suicide risk, 83% also had sleep problems.

Using regression analysis, Dr. Becker and his associates found that the odds of being classified with suicide risk were 6.5 times greater for students with depression and 2.7 times greater for those with sleep problems.

The results add to the literature suggesting that sleep would be an “important component to include in screening and intervention efforts to prevent suicidal ideation and attempts on college campuses,” the researchers wrote.

AUSTIN, TEX. – A new treatment for endometriosis-related pain, Elagolix, showed evidence of being effective long term, according to a study presented at the annual clinical and scientific meeting of the American College of Obstetricians and Gynecologists.

Elagolix, an oral nonpeptide gonadotropin-releasing hormone (GnRH) antagonist, manufactured by AbbVie, would be the first treatment of its kind if approved by the Food and Drug Administration, and would fulfill a needed relief for a more tolerable approach to severe endometriosis patients, according to presenter Eric S. Surrey, MD, medical director at the Colorado Center of Reproductive Medicine, Lone Tree.

“There have been no new medications approved for a long time for systematic endometriosis and there is a huge gap because the current options are expensive, and they are often injectable drugs,” said Dr. Surrey in an interview. “This would be an oral agent, which would be fabulous because it allows for a lot of flexibility and for many patients this could be much less concerning than using something long acting.”

To test the long-term effects of Elagolix, investigators studied 570 women with moderate to severe endometriosis-related pain who had gathered to participate in a previous phase 3, randomized, placebo-controlled trial concerning the drug’s effectiveness.

In the two extension studies, all participants were given either a 150- or 200-mg dose of Elagolix.

Average age of each patient group was between 31 and 34 years, and all groups were majority white, with a mean length of time from surgical diagnosis ranging from 45.5 to 56.6 months.

Patient improvements in dysmenorrhea and nonmenstrual pelvic pain continued between the first 6 months and 12 months of treatment, with a decrease of 46%-77% in the overall number of analgesics taken per day.

After 12 months of consecutive treatment, patients given 150 mg of Elagolix saw mean dysmenorrhea scores improve by 49%-53% from baseline, and by 82% for those at 200 mg, with certain expected adverse events, according to Dr. Surrey.

One of the most common adverse events associated with Elagolix was hot flashes, an unsurprising finding for Dr. Surrey and his colleagues considering Elagolix is a drug that lowers estrogen levels. However, any hot flashes patients experienced during the trial were still better than those associated with current medications, according to Dr. Surrey.

“In this extension study nobody dropped out because of hot flashes in the additional 6-month extension time,” Dr. Surrey explained. “If you look at the gold standard drug for endometriosis now, which is a GnRH agonist, which are highly available and are either injectable or implants, [patients taking these drugs] can have very severe hot flashes that require additional medication to alleviate the hot flashes at the same time.”

Patients did also experience some loss in bone density; however, Dr. Surrey argues the frequency and level of these adverse events is still better than current treatment options. One patient was required to discontinue the trial for bone density loss.

Currently, Elagolix is under FDA priority review, and if approved will be the first oral endometriosis treatment approved in over a decade, according to Dr. Surrey.

Dr. Surrey and several coauthors receive financial support from AbbVie as consultants, board members, and/or employees. Dr. Surrey and Dr. Taylor receive additional support from companies including Pfizer, Bayer, and Obseva.

TORONTO – Among infants up to 60 days old with an invasive bacterial infection, adverse outcomes are associated with prematurity, ill appearance, and bacterial meningitis, a multicenter retrospective analysis found.

“Young infants are susceptible to serious bacterial infections, particularly when they’re less than 60 days of age,” Christopher Pruitt, MD, said at the annual Pediatric Academic Societies meeting. “Among these infants, bacteremia and bacterial meningitis, also referred to as invasive bacterial infections, are associated with higher rates of morbidity and mortality.”

Doug Brunk/MDedge News

Of the 442 infants included in the final analysis, the majority (80%) had bacteremia, 14% had bacterial meningitis plus bacteremia, and 6% had bacterial meningitis only. “For purposes of this study, patients with bacterial meningitis with or without bacteremia were categorized as having bacterial meningitis,” Dr. Pruitt said. He and his associates found that 14.5% of infants had one or more adverse outcomes. Adverse outcomes occurred in 39% of infants with bacterial meningitis, compared with 8.2% of infants with isolated bacteremia. Need for mechanical ventilation, vasoactive medications, and neurologic disability also was more common among infants with bacterial meningitis than it was among children with isolated bacteremia. There were 10 deaths overall, which amounted to about 2% in both groups.

On multivariate analysis, the rate of adverse outcomes was significantly higher for patients with bacterial meningitis than it was for those with isolated bacteremia (adjusted odds ratio, 8.8), for premature versus term infants (AOR, 5.9), for infants who were ill appearing versus non-ill appearing (AOR, 3.9), and for infants with no fever versus those with fever (AOR, 2.4). No significant associations with 30-day adverse outcomes were seen in patients with a complex chronic condition, compared with those without a complex chronic condition (AOR, 2.0), nor in the those aged 29-60 days versus those younger than 29 days (15% vs. 14%, respectively; AOR 0.7).

“When looking at the most common scenario – a full-term infant without an ill appearance, and bacteremia as opposed to bacterial meningitis – 3 of these 219 infants, or 1.4%, had an adverse outcome,” said Dr. Pruitt, who cares for patients in the ED at Children’s of Alabama in Birmingham. “And there were no deaths.” He also reported that 12 infants with invasive bacterial infections were discharged from the index ED visit without antimicrobial treatment. All had bacteremia and none had an adverse outcome.

Dr. Pruitt acknowledged certain limitations of the study, including its retrospective design, that the outcomes were limited to 30 days, and the fact that the findings may not be generalizable to nontertiary settings. “Our findings have important implications for the care of infants with invasive bacterial infections,” he concluded. “In particular, the high rate of adverse outcomes for infants with bacterial meningitis can provide some context for clinicians in assessing the need for diagnostic evaluation for invasive bacterial infection and discussing testing and treatment with parents. Our findings may also help to inform inpatient management for hospitalized infants with invasive bacterial infections, as well as anticipatory guidance for parents, particularly around follow-up. Further prospective studies evaluating the long-term outcomes of infants with invasive bacterial infections are needed.”

The study was supported in part by a grant from the National Institutes of Health. Dr. Pruitt reported having no financial disclosures.

Need for mechanical ventilation, vasoactive medications, and neurologic disability also was more common among infants with bacterial meningitis than it was among children with isolated bacteremia. There were 10 deaths overall, which amounted to about 2% in both groups.

On multivariate analysis, the rate of adverse outcomes was significantly higher for patients with bacterial meningitis than it was for those with isolated bacteremia (adjusted odds ratio, 8.8), for premature versus term infants (AOR, 5.9), for infants who were ill appearing versus non-ill appearing (AOR, 3.9), and for infants with no fever versus those with fever (AOR, 2.4). No significant associations with 30-day adverse outcomes were seen in patients with a complex chronic condition, compared with those without a complex chronic condition (AOR, 2.0), nor in the those aged 29-60 days versus those younger than 29 days (15% vs. 14%, respectively; AOR 0.7).

“When looking at the most common scenario – a full-term infant without an ill appearance, and bacteremia as opposed to bacterial meningitis – 3 of these 219 infants, or 1.4%, had an adverse outcome,” said Dr. Pruitt, who cares for patients in the ED at Children’s of Alabama in Birmingham. “And there were no deaths.” He also reported that 12 infants with invasive bacterial infections were discharged from the index ED visit without antimicrobial treatment. All had bacteremia and none had an adverse outcome.

Dr. Pruitt acknowledged certain limitations of the study, including its retrospective design, that the outcomes were limited to 30 days, and the fact that the findings may not be generalizable to nontertiary settings. “Our findings have important implications for the care of infants with invasive bacterial infections,” he concluded. “In particular, the high rate of adverse outcomes for infants with bacterial meningitis can provide some context for clinicians in assessing the need for diagnostic evaluation for invasive bacterial infection and discussing testing and treatment with parents. Our findings may also help to inform inpatient management for hospitalized infants with invasive bacterial infections, as well as anticipatory guidance for parents, particularly around follow-up. Further prospective studies evaluating the long-term outcomes of infants with invasive bacterial infections are needed.”

TORONTO – Among infants up to 60 days old with an invasive bacterial infection, adverse outcomes are associated with prematurity, ill appearance, and bacterial meningitis, a multicenter retrospective analysis found.

“Young infants are susceptible to serious bacterial infections, particularly when they’re less than 60 days of age,” Christopher Pruitt, MD, said at the annual Pediatric Academic Societies meeting. “Among these infants, bacteremia and bacterial meningitis, also referred to as invasive bacterial infections, are associated with higher rates of morbidity and mortality.”

Of the 442 infants included in the final analysis, the majority (80%) had bacteremia, 14% had bacterial meningitis plus bacteremia, and 6% had bacterial meningitis only. “For purposes of this study, patients with bacterial meningitis with or without bacteremia were categorized as having bacterial meningitis,” Dr. Pruitt said. He and his associates found that 14.5% of infants had one or more adverse outcomes. Adverse outcomes occurred in 39% of infants with bacterial meningitis, compared with 8.2% of infants with isolated bacteremia.

Background: Antibiotic use is associated with an increased risk of C. difficile infection. Multiple studies have investigated the effects of probiotics in reducing the risk of C. difficile infection with varied results. This meta-analysis aims to assess the efficacy and safety of probiotics in reducing the risk of CDAD in patients taking antibiotics.

Study design: Meta-analysis.

Setting: A comprehensive electronic search for randomized, controlled trials investigating probiotics for prevention of CDAD or C. difficile infection were considered for inclusion. There were no language, publication status, or date limits applied.

Synopsis: This meta-analysis included 31 trials (8,672 participants) evaluating the relationship between probiotics and CDAD. The outcomes were pooled using a random effects model to calculate risk ratios and 95% confidence intervals. A complete case analysis suggested that probiotics reduce the risk of CDAD by 60% (1.5% vs. 4.0%; relative risk, 0.40; 95% confidence interval, 0.3-0.52), although a post-hoc subgroup analysis showed a statistically significant benefit only among patients with a high CDAD baseline risk (greater than 5%). Adverse events were assessed in 32 trials (8,305 participants), and the pooled analysis indicated that probiotic use reduced the risk of adverse events by 17% (RR, 0.83; 95% CI, 0.71-0.97).

Limitations to this meta-analysis include missing data from patients lost to follow-up and lack of success in testing all fecal samples. Lastly, that the strongest data for the beneficial effects of probiotics were demonstrated in patients with a high baseline risk of developing CDAD limits the study’s applicability to the general population.

Bottom line: Probiotic use in immunocompetent patients undergoing treatment with antibiotics decreases the incidence of CDAD without an increase in adverse events.
