The ubiquitous use of e-mail has opened the proverbial “Pandora’s box” of access to psychiatrists. Our e-mail addresses are readily available online via search engines or on hospital Web sites. E-mail has become a convenient method of communicating with patients; however, it also has resulted in a proliferation of unsolicited e-mails sent to physicians from people they don’t know seeking professional advice.¹ If you publish medical literature or make media appearances, you may be contacted by such individuals requesting your expertise.

Unsolicited e-mails present psychiatrists with ethical and legal quandaries that force them to consider how they can balance the human reflex to offer assistance against the potential ramifications of replying. These conundrums include:

• whether the sender is an actual person, and whether he or she is asking for advice
• the risks of replying vs not replying
• the possibility that there is a plausible crisis or danger to the sender or others
• the potential for establishing a doctor–patient relationship by replying
• the legal liability that might be incurred by replying.²

Take preemptive measures

There is guidance on how to e-mail your patients and respond to solicited e-mails, but there is a dearth of literature on how to respond to unsolicited e-mails. Anecdotal reports and limited literature suggest several possible measures you could take for managing unsolicited e-mails:

• Establish a policy of never opening unsolicited e-mails
• Create a strict junk-mail filter to prevent unsolicited e-mails from being delivered to your inbox
• Set up an automatic reply stating that unwanted or unsolicited e-mails will not be read and/or that no reply will be provided
• Read unsolicited e-mails, but immediately delete them without replying
• Acknowledge the sender in a reply, but state that you are unable to assist and decline further contact
• Send a generic reply clarifying that you are unable to provide medical assistance, and encourage the sender to seek help locally.²

Despite the urge to help, consider the consequences

In addition to taking up valuable time, unsolicited e-mails create legal and ethical predicaments that could subject you to legal liability if you choose to reply. Even though your intentions may be altruistic and you want to be helpful, you may unknowingly create problems for yourself. Clinicians should carefully weigh the consequences of replying before clicking “send.”

Misuse of prescription opioids has led to a staggering number of patients developing addiction, which the National Institutes of Health (NIH) and Department of Health and Human Services (HHS) have identified as a health care crisis. In the United States, approximately 29% of patients prescribed an opioid misuse it, and approximately 80% of heroin users started with prescription opioids.^1,2 The NIH and HHS have outlined 5 priorities to help resolve this crisis:

1. Improve access to prevention, treatment, and recovery support services
2. Increase availability and distribution of overdose-reversing medications
3. As the epidemic changes, strengthen what we know with improved public health surveillance
4. Support research that advances the understanding of pain and addiction and that develops new treatments and interventions
5. Improve pain management by utilizing evidence-based practices and reducing opioid misuse and opiate-related harm.³

Treating chronic pain in patients with bipolar disorder

At the Missouri University Psychiatric Center, an inpatient psychiatric ward, we recently conducted a retrospective cohort study to identify effective alternatives for treating pain, and to decrease opioid-related harm. Our study focused on 73 inpatients experiencing exacerbation of bipolar I disorder who also had chronic pain. These patients were treated with mood stabilizers, including lithium and carbamazepine. Patients also were taking medications, as needed, for agitation and their home medications for various medical problems. Selection of mood stabilizer therapy was non-random by standard of care based on best clinical practices. Dosing was based on blood-level monitoring adjusted to maintain therapeutic levels while receiving inpatient care. The average duration of inpatient treatment was approximately 1 to 5 weeks.

Pain was measured at baseline and compared with daily pain scores after mood stabilizer therapy using a 10-point scale, with 0 for no pain to 10 for worse pain, for the duration of the admission As expected based on the findings of previous research, carbamazepine resulted in a decrease in average daily pain score by 1.25 points after treatment (P = .048; F value = 4.3; F-crit = 4.23; calculated by one-way analysis of variance). However, patients who received lithium experienced a greater decrease in average daily pain score, by 2.17 points after treatment (P = .00035; F value = 14.56; F-crit = 4.02).

To further characterize the relationship between bipolar disorder and chronic pain, we looked at change in pain scores for mixed, manic, and depressive episodes of bipolar disorder by Clinical Global Impressions—Improvement (CGI-I) Scale categories (Figure). Participants who experienced the greatest clinical improvement also experienced the highest degree of analgesia. Those in the “Very much improved” CGI-I category experienced an almost 3-point decrease in average daily pain scores, with significance well below threshold (P = .0000967; F value = 19.83; F-crit = 4.11). Participants who showed no change in their bipolar I disorder symptoms or experienced exacerbation of their symptoms showed a significant increase in pain scores (P = .037; F value = 6.24; F-crit = 5.32).

Our data show that lithium and carbamazepine provide clinically and statistically significant analgesia in patients with bipolar I disorder and chronic pain. Furthermore, exacerbation of bipolar I disorder symptoms was associated with an increase of approximately 4 points on a 10-point chronic pain scale. While lithium and carbamazepine already are frequently used to treat patients with bipolar disorder, these medications may be particularly helpful for those with comorbid chronic pain.

A 39-year-old woman presented to the emergency department for evaluation of diffuse redness, itching, and tenderness of her skin. The patient said the eruption began 4 months earlier as localized plaques on her scalp, elbows, and beneath both breasts. Over the course of a few days, the redness became more diffuse, affecting most of her body. She also noticed swelling and skin desquamation on her lower extremities.

The patient had visited multiple urgent care clinics and underwent several courses of prednisone with initial improvement of symptoms, but experienced recurrence shortly after finishing the tapers.

On physical examination, more than 95% of the patient’s skin was bright red and tender to the touch, with associated exfoliation (FIGURES 1A-1B). Her lower extremities had pitting edema with superficial erosions that were weeping serous fluid. She was afebrile and normotensive, but had shaking chills and was tachycardic, with a heart rate of 115 bpm. There was no nail pitting, pustules, or lymphadenopathy. Lab tests revealed a low albumin level of 2.2 g/dL (normal: 3.5-5.5 g/dL), an elevated white blood cell count of 14,700 cells/mcL (normal: 4500-11,000 cells/mcL), and normocytic anemia (low hemoglobin of 8.7 g/dL; normal: 12-15.5 g/dL). The patient was admitted.

WHAT IS YOUR DIAGNOSIS?
HOW WOULD YOU TREAT THIS PATIENT?

Based on the patient’s clinical presentation, we diagnosed severe erythroderma secondary to psoriasis. A punch biopsy was performed, and pathology demonstrated subacute spongiotic dermatitis with superficial neutrophilic infiltrates, consistent with psoriasis.

Erythroderma is widespread reddening of the skin associated with desquamation, typically involving more than 90% of the body’s surface area.¹ In most instances, erythroderma is a clinical presentation of an existing dermatosis. The most common causative conditions include primary skin disorders (such as psoriasis or atopic dermatitis), idiopathic erythroderma, and drug eruptions. Less common causes include cutaneous T-cell lymphoma, pityriasis rubra pilaris, and contact dermatitis.¹

Erythroderma is usually a clinical presentation of an existing dermatosis, such as psoriasis or atopic dermatitis.

It’s unclear why some skin diseases progress to erythroderma; the pathogenesis is complicated and involves keratinocytes and lymphocytes interacting with adhesion molecules and cytokines. Erythroderma can arise at any age and occurs in all races, but is more common in males and older adults, with a mean age of 42 to 61 years.² The annual incidence of erythroderma is estimated to be one per 100,000 adults.³

A complete picture of the patient is essential to making the diagnosis

Diagnosis can be difficult and hinges on historical and physical exam findings, as well as lab evaluations and skin biopsies. The history should focus on current and former medications, while the physical exam should hone in on clinical manifestations of existing dermatoses. The most common extracutaneous finding is generalized lymphadenopathy, which if prominent, may warrant lymph node biopsy, with studies for evaluation of underlying lymphoma.

Tachycardia develops in 40% of patients, secondary to increased blood flow to the skin and fluid loss, with risk of high-output cardiac failure.² Patients often have chills because their skin is not able to regulate their body temperature normally.⁴

The lab evaluation should include a complete blood count with differential and a comprehensive metabolic panel, as well as blood, skin, and urine cultures if infection is suspected as an inciting factor. Typical findings include mild anemia, leukocytosis, eosinophilia, and an elevated erythrocyte sedimentation rate.⁵ In addition, patients with chronic erythroderma commonly have low albumin.⁶ Unfortunately, lab studies don’t always reveal the underlying cause of the erythroderma.

Biopsies are commonly performed. However, the underlying etiology is often not clearly reflected in the result. Histology is typically nonspecific; findings frequently include hyperkeratosis, acanthosis, spongiosis, and perivascular inflammatory infiltrate. Additionally, the prominence of histologic features may vary depending on the stage of disease and the severity of inflammation. More specific findings may become evident later in the disease as the erythroderma clears, so repeated skin biopsies over time may be needed for diagnosis.⁷

Consider these conditions, which can lead to erythroderma

First and foremost, it is important to get a thorough history, particularly about prior skin conditions and symptoms that may indicate the presence of undiagnosed skin conditions.

Psoriasis is one of the most common causes of erythroderma. A history of pre-existing psoriasis is very helpful, but when this is not present, a biopsy can help confirm a clinical suspicion for psoriasis. It also helps to look for clues of psoriasis like nail changes or a history of plaques over the elbows and knees.

Atopic dermatitis is another common cause of erythroderma, and the history might include scaling and erythematous patches or plaques involving flexural surfaces before erythroderma occurs. Patients may have a history of atopic dermatitis from childhood and/or a history of other atopic conditions such as asthma and allergic rhinitis.

Drug eruptions occur following the administration of a new medication and can mimic a myriad of dermatoses.

Cutaneous T-cell lymphoma can lead to erythroderma and be differentiated with skin biopsy; pathology may show atypical lymphocytes, and Pautrier’s microabscesses may be seen.⁸

Pityriasis rubra pilaris is a relatively rare condition that presents with red-orange scaling patches and thickened yellowish palms and soles.⁹

Tx targets underlying etiology and associated complications

When treating a patient with erythroderma, it’s important to prevent hypothermia and secondary infections. If symptoms are severe, hospitalization should be considered. Nutrition should be assessed, and any fluid or electrolyte imbalances should be corrected.

Hospitalization should be considered to prevent hypothermia and secondary infections, as well as to assess nutrition and correct any fluid or electrolyte imbalances.

Oral antihistamines are commonly administered to suppress associated pruritus. Topical treatment usually consists of corticosteroids under occlusion with bland emollients. Depending upon the underlying disease, the following systemic medications may be started: methotrexate 7.5 to 15 mg once/week; acitretin 10 to 25 mg/d; or cyclosporine 2.5 to 5  mg/kg/d; in addition to topical treatment.⁴

Our patient. Pathology for our patient was indicative of psoriasis. She was started on a regimen of cyclosporine 4 to 5 mg/kg/d, diphenhydramine 25 to 50 mg as needed for itching, triamcinolone 0.1% ointment under wet wraps to her trunk and extremities, and hydrocortisone 2.5% ointment to be applied to her face daily. She was released after 5 days in the hospital. At outpatient follow-up one week later, her erythroderma was resolving. One month later, her erythroderma was resolved (FIGURE 2), although she did have psoriatic plaques on her lower legs.

Typical findings include mild anemia, leukocytosis, eosinophilia, and an elevated erythrocyte sedimentation rate.⁵ In addition, patients with chronic erythroderma commonly have low albumin.⁶ Unfortunately, lab studies don’t always reveal the underlying cause of the erythroderma.

Biopsies are commonly performed. However, the underlying etiology is often not clearly reflected in the result. Histology is typically nonspecific; findings frequently include hyperkeratosis, acanthosis, spongiosis, and perivascular inflammatory infiltrate. Additionally, the prominence of histologic features may vary depending on the stage of disease and the severity of inflammation. More specific findings may become evident later in the disease as the erythroderma clears, so repeated skin biopsies over time may be needed for diagnosis.⁷

Consider these conditions, which can lead to erythroderma

First and foremost, it is important to get a thorough history, particularly about prior skin conditions and symptoms that may indicate the presence of undiagnosed skin conditions.

Psoriasis is one of the most common causes of erythroderma. A history of pre-existing psoriasis is very helpful, but when this is not present, a biopsy can help confirm a clinical suspicion for psoriasis. It also helps to look for clues of psoriasis like nail changes or a history of plaques over the elbows and knees.

Atopic dermatitis is another common cause of erythroderma, and the history might include scaling and erythematous patches or plaques involving flexural surfaces before erythroderma occurs. Patients may have a history of atopic dermatitis from childhood and/or a history of other atopic conditions such as asthma and allergic rhinitis.

Drug eruptions occur following the administration of a new medication and can mimic a myriad of dermatoses.

Cutaneous T-cell lymphoma can lead to erythroderma and be differentiated with skin biopsy; pathology may show atypical lymphocytes, and Pautrier’s microabscesses may be seen.⁸

Pityriasis rubra pilaris is a relatively rare condition that presents with red-orange scaling patches and thickened yellowish palms and soles.⁹

Tx targets underlying etiology and associated complications

When treating a patient with erythroderma, it’s important to prevent hypothermia and secondary infections. If symptoms are severe, hospitalization should be considered. Nutrition should be assessed, and any fluid or electrolyte imbalances should be corrected.

Hospitalization should be considered to prevent hypothermia and secondary infections, as well as to assess nutrition and correct any fluid or electrolyte imbalances.

Oral antihistamines are commonly administered to suppress associated pruritus. Topical treatment usually consists of corticosteroids under occlusion with bland emollients. Depending upon the underlying disease, the following systemic medications may be started: methotrexate 7.5 to 15 mg once/week; acitretin 10 to 25 mg/d; or cyclosporine 2.5 to 5  mg/kg/d; in addition to topical treatment.⁴

Our patient. Pathology for our patient was indicative of psoriasis. She was started on a regimen of cyclosporine 4 to 5 mg/kg/d, diphenhydramine 25 to 50 mg as needed for itching, triamcinolone 0.1% ointment under wet wraps to her trunk and extremities, and hydrocortisone 2.5% ointment to be applied to her face daily. She was released after 5 days in the hospital. At outpatient follow-up one week later, her erythroderma was resolving. One month later, her erythroderma was resolved (FIGURE 2), although she did have psoriatic plaques on her lower legs.

“Good morning, Mr. Harris. What can I do for you today?”

“Dr. Hickner, I need an MRI of my right knee. I hurt it last week, and I need to find out if I tore something.”

We all know that too many patients request—and often get—costly (and unnecessary) magnetic resonance imaging (MRI) and computed tomography (CT) scans of their joints and backs. That’s why such imaging is targeted in the Choosing Wisely campaign, which aims to eliminate needless testing.¹

But how can we confidently tell Mr. Harris that he doesn’t need an MRI or CT scan? One approach is to explain that imaging is generally reserved for those considering surgery, as it serves to inform the surgeon of the exact procedure needed. Another approach is to be skilled in physical exam techniques that increase our confidence in the clinical diagnosis.

Applying this to acute knee injuries. In this issue of JFP, Koster and colleagues explain that the Lachman test (and possibly the newer lever sign test) are maneuvers that have a high probability of ruling out complete anterior cruciate ligament (ACL) tears when performed properly. The Lachman test, for example, has a 96% sensitivity for complete ACL ruptures.² (The anterior drawer test has too low a sensitivity to rule out ACL injuries, and the pivot shift test is a bit too challenging to be performed reliably.)

A thorough physical exam and selective plain x-rays are all that is needed for the initial evaluation of most knee injuries.

This is important information because early surgery for ACL tears leads to better outcomes for athletes, and a reliable physical exam to rule out an ACL tear reduces the need for imaging. Moreover, other than fractures near the knee, no other knee injuries require early surgery. So a thorough physical exam and selective plain x-rays are all that is needed for the initial evaluation of most knee injuries.

The same is true for back and shoulder injuries, where acute imaging with MRI or CT is rarely called for. A thorough and accurate physical examination is usually sufficient, supplemented with plain X-rays on a selective basis.

Going one step further, consider taking a look at the JAMA series called, “The Rational Clinical Examination,” which has been compiled into a single publication by the same name.³ It is an excellent guide to the sensitivity, specificity, and positive and negative likelihood ratios of a host of clinical findings and tests. It can help to greatly improve clinical skills and reduce unnecessary testing.

THE CASE

A 12-year-old girl presented to my office (JH) with bilateral wrist pain. She had fallen on both wrists palmar-flexed and then, while trying to get up, landed on both wrists dorsi-flexed. The patient did not hear any “pops,” but felt immediate pain when her wrists hyperextended. Hand, wrist, and forearm x-rays were negative bilaterally for fractures. She was placed in bilateral thumb spica splints.

At follow-up one week later, the patient reported 6/10 pain in her left wrist and 7/10 pain in her right wrist. The pain increased to 10/10 bilaterally with movement and was not relieved by icing or nonsteroidal anti-inflammatory drugs. On physical exam, there was bilateral swelling of the wrists without ecchymosis or erythema. The patient had limited passive and active range of motion, especially during wrist extension. She also had tenderness to palpation over the anatomical snuff box, extending proximally to the distal radius bilaterally. She had no tenderness over the ulna or metacarpals, no loss of sensation in any area nerves, and she was neurovascularly intact bilaterally.

Based on the mechanism of injury, undetected fracture or full thickness ligament tear were both possible. Because of this, and because magnetic resonance imaging (MRI) entails no radiation exposure, MRI was chosen for additional imaging of both wrists.

THE DIAGNOSIS

The MRI revealed bilateral, nondisplaced, extra-articular fractures extending through the scaphoid waist, with surrounding bone marrow edema. In the right wrist, the patient also had a low-grade partial tear of the membranous portion of the scapholunate interosseous ligament (SLIL) at the scaphoid attachment (FIGURE 1). In the left wrist, she also had a low-grade sprain of the SLIL without tear (FIGURE 2).

DISCUSSION

Carpal fractures account for 6% of all fractures.¹ Scaphoid fractures are the most common carpal bone fracture among all age groups, but account for only 0.4% of all pediatric fractures.^1-3 They’re commonly missed on x-rays because they are usually nondisplaced and hidden by other structures superimposed on the image.^1,2,4 Undetected, scaphoid fractures can cause prolonged interruption to the bone’s architecture, leading to avascular necrosis of the proximal portion of the scaphoid bone.^5,6

Bilateral scaphoid fractures are extremely rare and account for less than 1% of all scaphoid fractures.⁷ Very few of these cases have been published in the literature, and those that have been published have talked about the fractures being secondary to chronic stress fractures and as being treated with internal fixation (regardless of whether the fractures were nondisplaced or if the ligaments were intact).^6-9

Our patient was placed in bilateral fiberglass short-arm thumb spica casts. We tried conservative treatment measures first because she had help with her activities of daily living (ADLs). At a follow-up visit 2 weeks later, we switched the casts to long-arm thumb spica casts because of the patient’s ability to pronate and supinate her wrists in the short-arm versions. After one month of wearing the long-arm casts, we placed her back in bilateral short-arm casts for 2 weeks. Eight weeks after the fall, we removed the short-arm casts for reevaluation.

We obtained x-rays to assess for any new changes to the wrist and specifically the scaphoid bones. The x-rays showed almost completely healed scaphoid bones with good alignment, but the patient still had 5/10 pain in the left wrist and 8/10 pain in the right wrist with movement. We placed her in adjustable thermoformable polymer braces, which were removed when she bathed.

Scaphoid fractures are commonly missed on x-rays because they are usually nondisplaced and hidden by other structures superimposed on the image.

Due to the uniqueness of her injuries, our patient had weekly visits with her primary care provider (PCP) for the first 2 months of treatment, followed by bimonthly visits for the remainder. At 10 weeks after the fall, her pain with movement was almost gone and she began physical therapy. She also began removing the braces during sedentary activity in order to practice range-of-motion exercises to prevent excessive stiffness in her wrists. Our patient regained full strength and range of motion one month later.

One other published case report describes the successful union of bilateral scaphoid fractures using bilateral long-arm casts followed by short-arm casts.⁷ Similar to our patient’s case, full union of the scaphoid bones was achieved within 12 weeks.⁷ Together, these cases suggest that conservative treatment methods are a viable alternative to surgery.

TAKEAWAY

For patients presenting with wrist pain after trauma to the wrists, assess anatomical snuffbox tenderness and obtain x-rays. Do not be falsely reassured by negative x-rays in the presence of a positive physical exam, however, as scaphoid fractures are often hidden on x-rays. If tenderness at the anatomical snuffbox is present and doesn’t subside within a few days, apply a short-arm thumb splint and obtain subsequent imaging.

If bilateral, nondisplaced, stable scaphoid fractures are diagnosed, conservative treatment with long-arm and short-arm casts is a viable alternative to surgery. This treatment decision should be made on an individual basis, however, as it requires the patient to have frequent PCP visits, assistance with ADLs, and complete adherence to the treatment plan.

ILLUSTRATIVE CASE

A fussy 6-month-old infant is brought into the emergency department (ED) with a rectal temperature of 101.5° F. She is consolable, breathing normally, and appears well hydrated. You find no clear etiology for her fever and suspect that a urinary tract infection (UTI) may be the source of her illness. How do you proceed with obtaining a urine sample?

A febrile infant in the family physician’s office or ED is a familiar clinical situation that may require an invasive diagnostic work-up. Up to 7% of infants ages 2 to 24 months with fever of unknown origin may have a UTI.² Collecting a urine sample from pre-toilet-trained children can be time consuming. In fact, obtaining a clean-catch urine sample in this age group took an average of more than one hour in one randomized controlled trial (RCT).³ More convenient methods of urine collection, such as placing a cotton ball in the diaper or using a perineal collection bag, have contamination rates of up to 63%.⁴

The American Academy of Pediatrics (AAP) guidelines for evaluating possible UTI in a febrile child <2 years of age recommend obtaining a sample for urinalysis “through the most convenient means.”⁵ If urinalysis is positive, only urine obtained by catheterization or suprapubic aspiration should be cultured. Guidelines from the National Institute for Health and Care Excellence in the United Kingdom are similar, but allow for culture of clean-catch urine samples.⁶

A recent prospective cohort study examined a noninvasive alternating lumbar-bladder tapping method to stimulate voiding in infants ages 0 to 6 months.⁷ Within 5 minutes, 49% of the infants provided a clean-catch sample, with contamination rates similar to those of samples obtained using invasive methods.⁷ Younger infants were more likely to void within the time allotted. Another trial of bladder tapping conducted in hospitalized infants <30 days old showed similar results.⁸

There are, however, no previously reported randomized trials demonstrating the efficacy of a noninvasive urine collection technique in the outpatient setting.

Use of invasive collection methods requires skilled personnel and may cause significant discomfort for patients (and parents). Noninvasive methods, such as bag urine collection, have unacceptable contamination rates. In addition, waiting to catch a potentially cleaner urine sample is time-consuming, so better strategies to collect urine from infants are needed. This RCT is the first to examine the efficacy of a unique stimulation technique to obtain a clean-catch urine sample from infants ages 1 to 12 months.

STUDY SUMMARY

Noninvasive stimulation method triggers faster clean urine samples

A nonblinded, single-center RCT conducted in Australia compared 2 methods for obtaining a clean-catch urine sample within 5 minutes: the Quick-Wee method (suprapubic stimulation with gauze soaked in cold fluid) or usual care (waiting for spontaneous voiding with no stimulation).¹ Three hundred fifty-four infants (ages 1-12 months) who required urine sample collection were randomized in a 1:1 ratio; allocation was concealed. Infants with anatomic or neurologic abnormalities and those needing immediate antibiotic therapy were excluded.

Almost one-third of patients provided successful clean-catch samples within 5 minutes.

The most common reasons for obtaining the urine sample were fever of unknown origin and “unsettled baby,” followed by poor feeding and suspected UTI. The primary outcome was voiding within 5 minutes; secondary outcomes included time to void, whether urine was successfully caught, contamination rate, and parent/clinician satisfaction.

Study personnel removed the diaper, then cleaned the genitals of all patients with room temperature sterile water. A caregiver or clinician was ready and waiting to catch urine when the patient voided. In the Quick-Wee group, a clinician rubbed the patient’s suprapubic area in a circular fashion with gauze soaked in refrigerated saline (2.8° C). At 5 minutes, clinicians recorded the voiding status and decided how to proceed.

Using intention-to-treat analysis, 31% of the patients in the Quick-Wee group voided within 5 minutes, compared with 12% of the usual-care patients. Similarly, 30% of patients in the Quick-Wee group provided a successful clean-catch sample within 5 minutes compared with 9% in the usual-care group (P<.001; number needed to treat=4.7; 95% CI, 3.4-7.7). Contamination rates were no different between the Quick-Wee and usual-care samples. Both parents and clinicians were more satisfied with the Quick-Wee method than with usual care (median score of 2 vs 3 on a 5-point Likert scale, in which 1 is most satisfied; P<.001). There was no difference when results were adjusted for age or sex. No adverse events occurred.

WHAT’S NEW

New method could reduce the need for invasive sampling

A simple suprapubic stimulation technique increased the number of infants who provided a clean-catch voided urine sample within 5 minutes—a clinically relevant and satisfying outcome. In appropriate patients, use of the Quick-Wee method to obtain a clean-catch voided sample for initial urinalysis, rather than attempting methods with known high contamination rates, may potentially reduce the need for invasive sampling using catheterization or suprapubic aspiration.

CAVEATS

Complete age range and ideal storage temperature are unknown

Neonates and pre-continent children older than 12 months were not included in this trial, so these conclusions do not apply to those groups of patients. The intervention period lasted only 5 minutes, but other published studies suggest that this amount of time is adequate for voiding to occur.^6,7 Although this study used soaking fluid stored at 2.8° C, the ideal storage temperature is unknown.

CHALLENGES TO IMPLEMENTATION

AAP doesn’t endorse clean-catch urine samples for culture

The Quick-Wee method is simple and easy to implement, and requires no specialized training or equipment. AAP guidelines do not endorse the use of clean-catch voided urine for culture, which may be a barrier to changing urine collection practices in some settings.

Noninvasive methods, such as bag urine collection, have unacceptable contamination rates. In addition, waiting to catch a potentially cleaner urine sample is time-consuming, so better strategies to collect urine from infants are needed. This RCT is the first to examine the efficacy of a unique stimulation technique to obtain a clean-catch urine sample from infants ages 1 to 12 months.

STUDY SUMMARY

Noninvasive stimulation method triggers faster clean urine samples

A nonblinded, single-center RCT conducted in Australia compared 2 methods for obtaining a clean-catch urine sample within 5 minutes: the Quick-Wee method (suprapubic stimulation with gauze soaked in cold fluid) or usual care (waiting for spontaneous voiding with no stimulation).¹ Three hundred fifty-four infants (ages 1-12 months) who required urine sample collection were randomized in a 1:1 ratio; allocation was concealed. Infants with anatomic or neurologic abnormalities and those needing immediate antibiotic therapy were excluded.

Almost one-third of patients provided successful clean-catch samples within 5 minutes.

The most common reasons for obtaining the urine sample were fever of unknown origin and “unsettled baby,” followed by poor feeding and suspected UTI. The primary outcome was voiding within 5 minutes; secondary outcomes included time to void, whether urine was successfully caught, contamination rate, and parent/clinician satisfaction.

Study personnel removed the diaper, then cleaned the genitals of all patients with room temperature sterile water. A caregiver or clinician was ready and waiting to catch urine when the patient voided. In the Quick-Wee group, a clinician rubbed the patient’s suprapubic area in a circular fashion with gauze soaked in refrigerated saline (2.8° C). At 5 minutes, clinicians recorded the voiding status and decided how to proceed.

Using intention-to-treat analysis, 31% of the patients in the Quick-Wee group voided within 5 minutes, compared with 12% of the usual-care patients. Similarly, 30% of patients in the Quick-Wee group provided a successful clean-catch sample within 5 minutes compared with 9% in the usual-care group (P<.001; number needed to treat=4.7; 95% CI, 3.4-7.7). Contamination rates were no different between the Quick-Wee and usual-care samples. Both parents and clinicians were more satisfied with the Quick-Wee method than with usual care (median score of 2 vs 3 on a 5-point Likert scale, in which 1 is most satisfied; P<.001). There was no difference when results were adjusted for age or sex. No adverse events occurred.

WHAT’S NEW

New method could reduce the need for invasive sampling

A simple suprapubic stimulation technique increased the number of infants who provided a clean-catch voided urine sample within 5 minutes—a clinically relevant and satisfying outcome. In appropriate patients, use of the Quick-Wee method to obtain a clean-catch voided sample for initial urinalysis, rather than attempting methods with known high contamination rates, may potentially reduce the need for invasive sampling using catheterization or suprapubic aspiration.

CAVEATS

Complete age range and ideal storage temperature are unknown

Neonates and pre-continent children older than 12 months were not included in this trial, so these conclusions do not apply to those groups of patients. The intervention period lasted only 5 minutes, but other published studies suggest that this amount of time is adequate for voiding to occur.^6,7 Although this study used soaking fluid stored at 2.8° C, the ideal storage temperature is unknown.

CHALLENGES TO IMPLEMENTATION

AAP doesn’t endorse clean-catch urine samples for culture

The Quick-Wee method is simple and easy to implement, and requires no specialized training or equipment. AAP guidelines do not endorse the use of clean-catch voided urine for culture, which may be a barrier to changing urine collection practices in some settings.

ILLUSTRATIVE CASE

A fussy 6-month-old infant is brought into the emergency department (ED) with a rectal temperature of 101.5° F. She is consolable, breathing normally, and appears well hydrated. You find no clear etiology for her fever and suspect that a urinary tract infection (UTI) may be the source of her illness. How do you proceed with obtaining a urine sample?

A febrile infant in the family physician’s office or ED is a familiar clinical situation that may require an invasive diagnostic work-up. Up to 7% of infants ages 2 to 24 months with fever of unknown origin may have a UTI.² Collecting a urine sample from pre-toilet-trained children can be time consuming. In fact, obtaining a clean-catch urine sample in this age group took an average of more than one hour in one randomized controlled trial (RCT).³ More convenient methods of urine collection, such as placing a cotton ball in the diaper or using a perineal collection bag, have contamination rates of up to 63%.⁴

The American Academy of Pediatrics (AAP) guidelines for evaluating possible UTI in a febrile child <2 years of age recommend obtaining a sample for urinalysis “through the most convenient means.”⁵ If urinalysis is positive, only urine obtained by catheterization or suprapubic aspiration should be cultured. Guidelines from the National Institute for Health and Care Excellence in the United Kingdom are similar, but allow for culture of clean-catch urine samples.⁶

A recent prospective cohort study examined a noninvasive alternating lumbar-bladder tapping method to stimulate voiding in infants ages 0 to 6 months.⁷ Within 5 minutes, 49% of the infants provided a clean-catch sample, with contamination rates similar to those of samples obtained using invasive methods.⁷ Younger infants were more likely to void within the time allotted. Another trial of bladder tapping conducted in hospitalized infants <30 days old showed similar results.⁸

There are, however, no previously reported randomized trials demonstrating the efficacy of a noninvasive urine collection technique in the outpatient setting.

Use of invasive collection methods requires skilled personnel and may cause significant discomfort for patients (and parents). Noninvasive methods, such as bag urine collection, have unacceptable contamination rates. In addition, waiting to catch a potentially cleaner urine sample is time-consuming, so better strategies to collect urine from infants are needed.

The Advisory Committee on Immunization Practices (ACIP) made relatively few new vaccine recommendations in 2017. One pertained to prevention of hepatitis B virus (HBV) infection in infants born to HBV-infected mothers. Another recommended a new vaccine to prevent shingles. A third advised considering an additional dose of mumps vaccine during an outbreak. This year’s recommendations pertaining to influenza vaccines were covered in a previous Practice Alert.¹

Perinatal HBV prevention: New strategy if revaccination is required

Hepatitis B prevention programs in the United States have decreased the incidence of HBV infections from 9.6 cases per 100,000 population in 1982 (the year the hepatitis B [HepB] vaccine was first available) to 1.1 cases per 100,000 population in 2015 (FIGURE 1).² One major route of HBV dissemination worldwide is perinatal transmission to infants by HBV-infected mothers. However, this route of infection has been greatly diminished in the United States because of widespread screening of pregnant women and because newborns of mothers with known active HBV infection receive prophylaxis with hepatitis B immune globulin and HBV vaccine.

Each year in the United States an estimated 25,000 infants are born to mothers who are positive for hepatitis B surface antigen (HBsAg).³ Without post-exposure prophylaxis, 85% of these infants would develop HBV infection if the mother is also hepatitis B e antigen (HBeAg) positive; 30% would develop HBV infection if the mother is HBeAg negative.² Eighty percent to 90% of infected infants develop chronic HBV infection and are at increased risk of chronic liver disease.² Of all infants receiving the recommended post-exposure prophylaxis, only about 1% develop infection.²

Available HepB vaccines. HepB vaccine consists of HBsAg derived from yeast using recombinant DNA technology, which is then purified by biochemical separation techniques. Three vaccine products are available for newborns and infants in the United States. Two are single-antigen vaccines—Engerix-B (GlaxoSmithKline Biologicals) and Recombivax HB (Merck & Co.)—and both can be used starting at birth. One combination vaccine, Pediarix (GlaxoSmithKline Biologicals) is used for children ages 6 weeks to 6 years. It contains HBsAg as do the other 2 vaccines, as well as diphtheria and tetanus toxoids, acellular pertussis adsorbed, and inactivated poliovirus (DTaP-HepB-IPV).

Until December 31, 2014, a vaccine combining HBsAg and haemophilus-B antigen, Comvax (Merck and Co.), was available for infants 6 weeks or older. Comvax is no longer produced.

Factors affecting the dosing schedule. For infants born to HBsAg-positive mothers, the final dose of the HepB series should be completed at age 6 months with either one of the monovalent HepB vaccines or the DTaP-HepB-IPV vaccine. When the now-discontinued Comvax was used to complete the series, the final dose was administered at 12 to 15 months. The timing of HepB vaccine at birth and at subsequent intervals, and a decision on whether to give hepatitis B immune globulin, depend on the baby’s birth weight, the mother’s HBsAg status, and type of vaccine used.²

Post-vaccination assessment. ACIP recommends that babies born to HBsAg-positive mothers and having received the final dose of the vaccine series be serologically tested for immunity to HBV at age 9 to 12 months; or if the series is delayed, at one to 2 months after the final dose.⁴ Infants without evidence of active infection (ie, HBsAg negative) and with levels of antibody to HBsAg ≥10 mIU/mL are considered protected and need no further vaccinations.⁴ Revaccination is advised for those with antibody levels <10 mIU/mL—who account for only about 2% of infants having received the recommended schedule.⁴

New revaccination strategy. The previous recommendation on revaccination advised a second 3-dose series with repeat serologic testing one to 2 months after the final dose of vaccine. Although this strategy is still acceptable, the new recommendation for infants with antibody levels <10 mIU/mL favors (for cost savings and convenience) administration of a single dose of HepB vaccine with retesting one to 2 months later.²

Several studies presented at the ACIP meeting in February 2017 showed that more than 90% of infants revaccinated with the single dose will develop a protective antibody level.⁴ Infants whose anti-HBs remain <10 mIU/mL following the single-dose re-vaccination should receive 2 additional doses of HepB vaccine, followed by testing one to 2 months after the last dose⁴ (FIGURE 2²).

(A new HepB vaccine, HEPLISAV-B [Dynavax Technologies Corp]), has been approved for use in adults. More on this in a bit.)

In 2017, the US Food and Drug Administration (FDA) approved a new vaccine against shingles, an adjuvanted herpes zoster subunit (HZ/su) vaccine, Shingrix (GlaxoSmithKline Biologicals). It is now an alternative to the live attenuated virus (ZVL) vaccine, Zostavax (Merck & Co.), licensed in 2006. ZVL is approved for use in adults ages 50 to 59 years, but ACIP recommends it only for adults 60 and older.⁵ It is given as a single dose, while HZ/su is given as a 2-dose series at 0 and at 2 to 6 months. By ACIP’s analysis, HZ/su is more effective than ZVL. In a comparison model looking at health outcomes over a lifetime among one million patients 60 to 69 years of age, HZ/su would prevent 53,000 more cases of shingles and 4000 more cases of postherpetic neuralgia than would ZVL.⁶

At its October 2017 meeting, ACIP voted to recommend HZ/su for adults ages 50 and older (including those previously vaccinated with ZVL), and to recommend HZ/su preferentially over the use of ZVL.⁷ More details on the ACIP considerations are contained in a recent JFP audiocast.⁸

Additional mumps vaccine is warranted in an outbreak

While use of mumps-containing vaccine in the United States has led to markedly lower disease incidence rates than existed in the pre-vaccine era, in recent years there have been large mumps outbreaks among young adults at universities and other close-knit communities. These groups have had relatively high rates of completion of 2 doses of measles, mumps, and rubella (MMR) vaccine, and the cause of the outbreaks is not fully understood. Potential contributors include waning immunity following vaccination and antigenic differences between the virus strains circulating and those in the vaccine.

ACIP considered whether a third dose of MMR should be recommended to those fully vaccinated if they are at high risk due to an outbreak. Although the evidence to support the effectiveness of a third dose was scant and of very low quality, the evidence for vaccine safety was reassuring and ACIP voted to recommend the use of a third dose in outbreaks.⁹

One new vaccine and others on the horizon

ACIP is evaluating a new HepB vaccine, HEPLISAV-B, which was approved by the FDA in November 2017 for use in adults.^10,11 The vaccine contains the same antigen as other available HepB vaccines but a different adjuvant. It is administered in 2 doses one month apart, which is preferable to the current 3-dose, 6-month schedule. There is, however, some indication that it causes increased rates of cardiovascular complications.¹⁰ ACIP is evaluating the relative effectiveness and safety of HEPLISAV-B and other HepB vaccines, and recommendations are expected this spring.

Other vaccines in various stages of development, but not ready for ACIP evaluation, include those against Zika virus, norovirus, respiratory syncytial virus, and dengue virus.

ACIP is also retrospectively assessing whether adding the 13 valent pneumococcal conjugate vaccine to the schedule for those over the age of 65 has led to improved pneumonia outcomes. It will reconsider the previous recommendation based on the results of its assessment.

A mother brought her 8-year-old daughter to our office for evaluation of vitiligo “down there” (FIGURE). The skin eruption first appeared on her vulva a year earlier and was intermittently pruritic. The lesions were initially smaller and red, but had since lightened in color, coalesced, and had begun to spread to the perianal area. The patient’s mother had received a call from her daughter’s teacher who observed that her daughter was scratching the area and might be masturbating in class.

The mother reported that 6 months earlier, her daughter had experienced bloody spots in her underwear accompanied by dysuria. The mother brought her to the emergency department, where she was treated with antibiotics for a urinary tract infection.

Our physical examination revealed well-circumscribed, symmetric, depigmented, confluent, crinkled, parchment-like plaques with small hemorrhagic erosions on the medial labia majora and minora. The lesions had spread to the perianal area with depigmentation superiorly and hypopigmentation inferiorly, creating a figure-8 pattern.

A review of systems was negative for pruritus, pain, dysuria, dyschezia, constipation, and vaginal discharge. The patient denied sexual activity, depression, or anxiety. Her mother denied behavioral changes in her daughter and said that her daughter hadn’t had any one-on-one time alone with any adults besides herself. Her mother was concerned that the white spots might spread to the rest of her daughter’s body, which could affect her socially.

WHAT IS YOUR DIAGNOSIS?
HOW WOULD YOU TREAT THIS PATIENT?

Based on the history and clinical findings, including the classic figure-8 pattern, we diagnosed childhood lichen sclerosus (LS) in this patient. LS is a chronic inflammatory skin disorder that primarily affects the genital mucosa. The disorder can present at any age, but is most common among postmenopausal women, with a prevalence estimated to be as high as one in 30.^1-3 A second incidence peak is observed in prepubescent girls, with a prevalence of one in 900.^3,4 LS is less common in men and boys, with a female-to-male ratio that can reach 10:1.⁵ The classic symptoms of LS are pruritus and pain, which may be intermittent or persistent.

In girls, initial manifestations may be constipation, dysuria, or even behavioral symptoms such as night fears, which can occur because children are less active at night and become more aware of urinary discomfort.^1,2,6 Typical signs of LS are thin atrophic plaques that spare the vagina and cervix. The plaques can be ivory-white, erythematous, or violaceous. Some patients have perianal lesions as well, and can display the pathognomonic figure-8 pattern of porcelain plaques around the vulva and anus.⁵

Up to 84% of cases of childhood lichen sclerosus are misdiagnosed, with an average delay of more than a year between symptom onset and diagnosis.

With more advanced disease, erosions, lichenification, and even distortion of vulvar architecture may occur.^2,4,7 In severe cases, labia resorption and clitoral phimosis may develop.⁵ Complications include secondary infection, dyspareunia, and psychosexual distress. The most worrisome sequela of LS is squamous cell carcinoma of the vulva (SCCV), which occurs in 5% of female patients with LS.⁴

In men and boys, LS typically involves the foreskin and the glans, while sparing the perianal region.⁵ Scarring of the foreskin can lead to phimosis, and patients may complain of painful erections and difficulty urinating. LS can also occur away from the genitalia in both males and females.

Autoimmune mechanisms, genetics, and hormones play a role

The exact pathogenesis of LS remains unknown, but multiple factors are likely at work.

Autoimmune mechanisms. Up to 60% of women with LS have an autoimmune disorder, which is most commonly vitiligo, alopecia areata, or thyroid disease.⁵ In addition, 67% of patients have autoantibodies against extracellular matrix protein 1, and 30% have them against bullous pemphigoid antigen 180.^1,8

Genetics. LS is associated with certain human leukocyte antigen class II haplotypes (especially DQ7) and with polymorphisms at the interleukin-1 receptor antagonist gene locus.^5,6,9

Hormones. The clear peaks of incidence during times of low estrogen, and a higher incidence in patients with Turner syndrome or kidney disease, suggest that low estrogen may play a role in the development of LS, as well.^1,5,6

While it is generally accepted that trauma may trigger LS via the Koebner phenomenon (the appearance of lesions at the site of injury), there is debate as to whether microbes—especially Borrelia burgdorferi and human papillomavirus (HPV)—might play a role.^1,5

Diagnosis is often delayed, misdiagnosis is common

The average delay from symptom onset to diagnosis of LS is 1.3 years, and up to 84% of childhood LS is misdiagnosed before referral.^2,9 The differential diagnosis includes:

Sexual abuse. In prepubertal girls presenting with genital redness, the can’t-miss diagnosis is sexual abuse, which occurs in more than 25% of children in the United States.¹⁰ Initial manifestations may be regression in developmental milestones, such as new-onset bedwetting, or behavioral changes such as social withdrawal or declining academic performance.¹¹

However, physicians must be conscientious about ruling out medical etiologies before prematurely diagnosing abuse. Fourteen percent of girls with LS are incorrectly diagnosed as having been sexually abused.² A clinical pearl is that while LS may resemble abuse on exam, it rarely affects the hymenal structure.¹² It is also important to keep in mind that the 2 entities are not incompatible, as sexual abuse leading to LS via Koebnerization is a well-described phenomenon.¹²

Lichen planus. LP, which is also an immune-mediated inflammatory disorder affecting the vulva, classically presents with the 6 Ps: pruritic, polygonal, planar, purple papules and plaques.⁴ LP is distinguished from LS by being rare in childhood, having a predilection for the flexor wrists, and involving the oral and vaginal mucosa.⁴

Lichen simplex chronicus (LSC) is a chronic, circumscribed, pruritic, eczematous condition that becomes lichenified with thickened skin secondary to repeated scratching.¹³ Children with atopic dermatitis can develop LSC, but other children can also develop the scratch-itch cycle that results in the thickened plaques of LSC. Like LS, LSC can occur in areas other than the genitalia, including the neck and feet.¹⁴

Allergic contact dermatitis can occur in the genital area from diaper creams, soaps, and perfumes. Irritant contact dermatitis can occur from exposure to diarrhea, bedwetting, and other irritants. Contact dermatitis is less likely to have the classic figure-8 pattern seen in LS.

Psoriasis in the genital area can be confused with LS. However, psoriasis favors the groin creases in what is called inverse psoriasis. In addition, psoriasis tends to involve multiple areas, including the extensor surfaces of the elbows and knees, the nails, and the scalp.

Vitiligo can present on the genitals as circumscribed hypopigmented and depigmented patches that are flat. Vitiligo is asymptomatic, and the only pathology is the change in skin color. With LS, there is lichenification, atrophy, and sclerosis.⁴ Vitiligo often occurs with bilateral symmetric involvement in areas of trauma including the face, neck, scalp, elbows, wrists, hands, knees, ankles, and feet.

Treatment aims to improve symptoms

LS is usually diagnosed clinically (especially in children, as a biopsy is a great challenge to perform). However, when the clinical presentation is unclear, a skin biopsy will demonstrate the diagnostic findings of thinning of the epidermis, loss of rete pegs, hyperkeratosis, and dermal fibrosis with a T-lymphocyte-dominant inflammatory infiltrate.^1,2,4,5

LS is a remitting and relapsing condition with no cure. The goals of treatment are to provide symptom relief and minimize scarring and atrophy,² but it is unknown whether treatment reduces the risk of malignancy.⁹

First-line treatment for both genders and all ages is ultrapotent topical corticosteroids; clobetasol propionate 0.05% is most commonly used.^1,6 Regimens vary, but the vast majority of patients improve within 3 months of once-daily treatment.⁴

Although lichen sclerosus may resemble abuse on exam, it rarely affects the hymenal structure.

For refractory LS, calcineurin inhibitors such as tacrolimus may be used. Although it has a black box warning regarding a potential cancer risk, long-term studies of children using tacrolimus for atopic dermatitis have not demonstrated an increased risk of malignancy.^6,9 Because of a considerable adverse effect profile, oral retinoids are limited to refractory cases in adults.⁶ Surgery is reserved for scarring and adhesions.⁴

Follow-up plays an important role in management

Historically, it was believed that pediatric LS had an excellent prognosis, with patients achieving complete resolution after puberty.^1,4 Recent findings have shown mixed results, with LS persisting in many patients beyond puberty.^2,4 Therefore, regular follow-up is recommended every 6 to 12 months.

For uncomplicated LS, specialist follow-up is not indicated. Female patients should regularly conduct self-examinations and, at a minimum, undergo annual examinations by their primary care physician. Those who require specialist follow-up include patients with difficult-to-control symptoms, hypertrophic lesions, a history of SCCV or differentiated vulvar intraepithelial neoplasia (dVIN), or pathology showing possible dVIN.¹⁵

Our patient. We prescribed clobetasol propionate 0.05% ointment to be used once daily for 8 weeks. We stressed the importance of genital self-examinations using a mirror to monitor for any concerning changes such as skin thickening. We showed the patient and her mother photos of normal female genitalia to help normalize the genital exam, and taught the patient how to find her plaques in the mirror. We set expectations by emphasizing the chronic nature of LS and the likelihood of recurrence. We also encouraged HPV vaccination in the upcoming years to prevent both cervical cancer and HPV-related SCCV.

EVIDENCE SUMMARY

A 2014 Cochrane meta-analysis of 5 RCTs with a total of 733 patients examined the effectiveness of any type of exercise in decreasing vasomotor symptoms in perimenopausal and postmenopausal women.¹ The studies compared exercise—defined as structured exercise or physical activity through active living—with no active treatment, yoga, or hormone therapy (HT) over a 3- to 24-month follow-up period.

Three trials of 454 women that compared exercise with no active treatment found no difference between groups in frequency or intensity of vasomotor symptoms (standard mean difference [SMD]= -0.10; 95% confidence interval [CI], -0.33 to 0.13).

Two trials with 279 women that compared exercise with yoga didn’t find a difference in reported frequency or intensity of vasomotor symptoms between the groups (SMD= -0.03; 95% CI, -0.45 to 0.38).

One small trial (14 women) of exercise and HT found that HT patients reported decreased frequency of flushes over 24 hours compared with the exercise group (mean difference [MD]=5.8; 95% CI, 3.17-8.43).

Overall, the evidence was of low quality because of heterogeneity in study design.¹

Two exercise interventions fail to reduce symptoms

A 2014 RCT, published after the Cochrane search date, investigated exercise as a treatment for VMS in 261 perimenopausal and postmenopausal women ages 48 to 57 years.² Patients had a history of at least 5 hot flashes or night sweats per day and hadn’t taken HT in the previous 3 months.

The women were randomized to one of 2 exercise interventions or a control group. The exercise interventions both entailed 2 one-on-one consultations with a physical activity facilitator and use of a pedometer. Patients were encouraged to perform 30 minutes of moderate-intensity exercise 3 days a week during Weeks 1 through 12, then increase the frequency to 3 to 5 days a week during Weeks 13 through 24. In one intervention arm, the women also received an informational DVD and 5 educational leaflets.

In the other arm, they were invited to attend 3 exercise support groups in their local community. The control group was offered an opportunity for exercise consultation and given a pedometer at the end of the study.

At the end of the 6-month intervention, neither exercise intervention significantly decreased self-reported hot flashes/night sweats per week compared with the control group (DVD exercise arm vs control: MD= -8.9; 95% CI, -20 to 2.2; social support exercise arm vs control: MD= -5.2; 95% CI, -16.7 to 6.3). The study also found no difference in hot flashes/night sweats per week at 12-month follow-up between the DVD exercise arm and controls (MD= -3.2; 95% CI, -12.7 to 6.4) and the social-support group and controls (MD= -3.5; 95% CI, -13.2 to 6.1).

Drug therapy relieves symptoms, but other methods—not so much

An analysis of pooled individual data from 3 RCTs compared exercise with 5 other interventions for VMS in 899 perimenopausal and postmenopausal women.³ Patients had at least 14 bothersome symptoms per week.

Exercise doesn't decrease the frequency or severity of vasomotor menopausal symptoms in perimenopausal and post-menopausal women.

The 6 interventions ranged from nonpharmacologic therapies, such as aerobic exercise and yoga, to pharmacologic treatments, including escitalopram 10 to 20 mg/d, venlafaxine 75 mg/d, oral estradiol (E2) 0.5 mg/d, and omega-3 supplementation 1.8 g/d. The primary outcome was a change in VMS frequency and bother as assessed by a symptom diary over the 4- to 12-week follow-up.

The analysis found a significant 6-week reduction in daily VMS frequency relative to placebo for escitalopram (MD= -1.4; 95% CI, -2.7 to -0.2), low-dose E2 (MD= -1.9; 95% CI, -2.9 to -0.9), and venlafaxine (MD= -1.3; 95% CI, -2.3 to -0.3). However, no difference in VMS frequency or bother was found with exercise (MD= -0.4; 95% CI, -1.1 to 0.3), yoga (MD= -0.6; 95% CI, -1.3 to 0.1), or omega-3 supplementation (MD= 0.2; 95% CI, -0.4 to 0.8).

RECOMMENDATIONS

The American College of Obstetricians and Gynecologists (ACOG) doesn’t offer specific recommendations regarding exercise as a treatment for symptoms of menopause. The 2014 ACOG guidelines for managing symptoms report that data don’t support phytoestrogens, supplements, or lifestyle modifications (Level B, based on limited or inconsistent evidence). ACOG recommends basic palliative measures such as drinking cool drinks and decreasing layers of clothing (Level B).⁴

The American Association of Clinical Endocrinologists’ recommendations don’t mention exercise as a menopause therapy.⁵

The North American Menopause Society’s 2015 statement regarding the nonhormonal treatment of menopause symptoms doesn’t recommend exercise as an effective therapy because of insufficient or inconclusive data.⁶

EVIDENCE SUMMARY

A 2014 Cochrane meta-analysis of 5 RCTs with a total of 733 patients examined the effectiveness of any type of exercise in decreasing vasomotor symptoms in perimenopausal and postmenopausal women.¹ The studies compared exercise—defined as structured exercise or physical activity through active living—with no active treatment, yoga, or hormone therapy (HT) over a 3- to 24-month follow-up period.

Three trials of 454 women that compared exercise with no active treatment found no difference between groups in frequency or intensity of vasomotor symptoms (standard mean difference [SMD]= -0.10; 95% confidence interval [CI], -0.33 to 0.13).

Two trials with 279 women that compared exercise with yoga didn’t find a difference in reported frequency or intensity of vasomotor symptoms between the groups (SMD= -0.03; 95% CI, -0.45 to 0.38).

One small trial (14 women) of exercise and HT found that HT patients reported decreased frequency of flushes over 24 hours compared with the exercise group (mean difference [MD]=5.8; 95% CI, 3.17-8.43).

Overall, the evidence was of low quality because of heterogeneity in study design.¹

Two exercise interventions fail to reduce symptoms

A 2014 RCT, published after the Cochrane search date, investigated exercise as a treatment for VMS in 261 perimenopausal and postmenopausal women ages 48 to 57 years.² Patients had a history of at least 5 hot flashes or night sweats per day and hadn’t taken HT in the previous 3 months.

The women were randomized to one of 2 exercise interventions or a control group. The exercise interventions both entailed 2 one-on-one consultations with a physical activity facilitator and use of a pedometer. Patients were encouraged to perform 30 minutes of moderate-intensity exercise 3 days a week during Weeks 1 through 12, then increase the frequency to 3 to 5 days a week during Weeks 13 through 24. In one intervention arm, the women also received an informational DVD and 5 educational leaflets.

In the other arm, they were invited to attend 3 exercise support groups in their local community. The control group was offered an opportunity for exercise consultation and given a pedometer at the end of the study.

At the end of the 6-month intervention, neither exercise intervention significantly decreased self-reported hot flashes/night sweats per week compared with the control group (DVD exercise arm vs control: MD= -8.9; 95% CI, -20 to 2.2; social support exercise arm vs control: MD= -5.2; 95% CI, -16.7 to 6.3). The study also found no difference in hot flashes/night sweats per week at 12-month follow-up between the DVD exercise arm and controls (MD= -3.2; 95% CI, -12.7 to 6.4) and the social-support group and controls (MD= -3.5; 95% CI, -13.2 to 6.1).

Drug therapy relieves symptoms, but other methods—not so much

An analysis of pooled individual data from 3 RCTs compared exercise with 5 other interventions for VMS in 899 perimenopausal and postmenopausal women.³ Patients had at least 14 bothersome symptoms per week.

Exercise doesn't decrease the frequency or severity of vasomotor menopausal symptoms in perimenopausal and post-menopausal women.

The 6 interventions ranged from nonpharmacologic therapies, such as aerobic exercise and yoga, to pharmacologic treatments, including escitalopram 10 to 20 mg/d, venlafaxine 75 mg/d, oral estradiol (E2) 0.5 mg/d, and omega-3 supplementation 1.8 g/d. The primary outcome was a change in VMS frequency and bother as assessed by a symptom diary over the 4- to 12-week follow-up.

The analysis found a significant 6-week reduction in daily VMS frequency relative to placebo for escitalopram (MD= -1.4; 95% CI, -2.7 to -0.2), low-dose E2 (MD= -1.9; 95% CI, -2.9 to -0.9), and venlafaxine (MD= -1.3; 95% CI, -2.3 to -0.3). However, no difference in VMS frequency or bother was found with exercise (MD= -0.4; 95% CI, -1.1 to 0.3), yoga (MD= -0.6; 95% CI, -1.3 to 0.1), or omega-3 supplementation (MD= 0.2; 95% CI, -0.4 to 0.8).

EVIDENCE SUMMARY

A 2011 blinded diagnostic accuracy study of 1000 adult chronic pain patients in an interventional pain management program in the United States compared POC immunoassay urine drug testing with LC-MS.¹ The immunoassay index test can be performed in the office with rapid results. The LC-MS reference test requires that the urine sample be sent to a lab.

Study participants were 37% male and 63% female, average age 51 years. Of the 1000 patients, 920 were prescribed opioids. Morphine, hydrocodone, codeine, and hydromorphone (morphine group) were tested with cutoff values of 300 ng/mL for POC testing and 50 ng/mL for LC-MS. Cutoffs for methadone were 300 ng/mL for POC and 100 ng/mL for LC-MS. For oxycodone, they were 100 ng/mL for POC and 50 ng/mL for LC-MS.

Methadone had the highest sensitivity and specificity at 96% and 99%, with a false-negative rate of 3.9% and a false-positive rate of 1.2%. It also had the highest agreement between the 2 testing methods at 99%. The morphine group had a sensitivity of 92%, specificity of 93%, false-negative rate of 7.8%, false-positive rate of 6.9%, and 93% test agreement. Oxycodone showed the lowest sensitivity at 75%; it had a specificity of 92%, a false-negative rate of 25%, a false-positive rate of 7.7%, and 90% test agreement.

More false negatives than with LC-MS  

A 2010 blinded diagnostic accuracy study of 4200 adults treated with opioids for chronic pain compared immunoassay urine testing with LC-MS for opioids, benzodiazepines, marijuana, cocaine, and methamphetamine between October and November 2008.² Urine samples were tested using both methods simultaneously on split specimens. Cutoff values for methadone, codeine, hydrocodone, hydromorphone, and morphine were 50 ng/mL on LC-MS. Immunoassay relative activity—the difference between the immunoassay and the LC-MS cutoffs—was 300 for methadone, 180 for codeine, 1700 for hydrocodone, 4000 for hydromorphone, and 300 for morphine.

Of the 3414 samples submitted for opiate testing, 2191 tested positive using immunoassay and 2233 tested positive using LC-MS for a total of 42 false-negative results with immunoassay. The positive rate (percentage of samples testing positive by LC-MS) was 65%, and the false-negative rate was 1.9%. Methadone testing produced 17 false-negative results; the positive rate was 10%, and the false-negative rate was 6.1%. The immunoassay false-positive results occurred in patients taking hydromorphone and hydrocodone.

The study was limited by lack of demographic information on the participants.
