Patients with AD should routinely be asked about conjunctivitis
according to a recent position statement from the International Eczema Council.
Patients with AD who develop conjunctivitis during dupilumab treatment may experience “bilateral inflammation of the anterior conjunctiva and hyperaemia of the limbus, which may cause nodular swelling.”according to the statement, which pertains to conjunctivitis in AD patients, “with and without dupilumab therapy.” (J Eur Acad Dermatol Venereol. 2019 May 6. doi: 10.1111/jdv.15608). Currently, there are no predictive factors of conjunctivitis and no guidance in the literature on how to manage conjunctivitis associated with dupilumab, which in some cases can make it necessary to stop treatment, the authors wrote.
The International Eczema Council (IEC) polled 86 dermatologists in 22 countries who are experts in AD; 46 members responded from 19 countries, including dermatologists from Australia, Canada, Denmark, France, Germany, Japan, Korea, the Netherlands, the United Kingdom, and the United States. The questions centered on the diagnosis and management of conjunctivitis in AD patients, and whether to refer cases to an ophthalmologist. Consensus was achieved if less than 30% of participants disagreed with a statement. IEC members then met in person at a European Academy of Dermatology and Venereology meeting in Paris to discuss the results of the survey. Survey respondents noted they had seen dupilumab-associated conjunctivitis in both pediatric and adult patients.
The IEC members recommended that:
- Patients should be informed about the risks of conjunctivitis before being prescribed dupilumab.
- AD patients should be asked “routinely” about ocular complaints or symptoms.
- AD patients with conjunctivitis should be referred to an ophthalmologist for diagnosis and treatment.
- AD patients with new-onset conjunctivitis during dupilumab treatment always should be referred to an ophthalmologist, especially in more severe cases such as when they do not respond to treatment with antihistamine or artificial tears.
- Dermatologists also should rule out keratoconjunctivitis before treating with dupilumab, as it may cause keratitis and blindness.
- Patients who have had keratoconjunctivitis in the past should not be precluded from treatment with dupilumab, and those who develop conjunctivitis during treatment should be referred to an ophthalmologist – but should stay on treatment while waiting for the consult.
“It was stressed that at this moment there are also no reliable data on the course of atopic keratoconjunctivitis and vernal keratoconjunctivitis during dupilumab treatment,” according to Jacob P. Thyssen, MD, PhD, Herlev and Gentofte Hospital, Hellerup, Denmark, and coauthors. These patients “should be carefully monitored by an ophthalmologist before and during treatment with dupilumab.”
The recommendations also centered around which treatments should be initiated by dermatologists, and which should be referred to ophthalmologists. Those patients with conjunctivitis should receive eye drops, eye ointment, or oral antihistamines from their dermatologists before an ophthalmology referral, the IEC members said. Dermatologists also should perform, or refer patients for, skin prick testing or specific IgE testing for aeroallergens in patients with AD who have conjunctivitis, and patch testing with an “ophthalmologic series, and native eye drops/ointments to diagnose possible delayed type hypersensitivity reactions to topical ingredients,” they added.
Among the treatments for conjunctivitis best left to ophthalmologists are cyclosporine, tacrolimus, or corticosteroid eye drops.
“Despite the more limited experience with eye drops by dermatologists, rapid access to ophthalmological service may be difficult, sometimes warranting a short course of corticosteroid eye drops without ophthalmological consultations,” Dr. Thyssen and associates said. “However, persistent or recurrent conjunctivitis requiring repeated or prolonged use of corticosteroid, tacrolimus, and ciclosporin-containing eye drops, must be managed by an ophthalmologist, given the risk of glaucoma, cataract, and infections.”
“The AD severity, conjunctivitis severity, possible contraindications, possible effect of dupilumab therapy on concomitant asthma or other comorbidities, as well as other treatment options, should be considered on an individual patient basis,” the authors concluded.
The IEC survey was limited by the small survey response and reliance on expert opinion.
The authors reported personal and institutional relationships in the form of grants, corporate sponsorships, advisory board memberships, investigator appointments, speakers bureau positions, and consultancies for a variety of pharmaceutical companies, agencies, societies, and other organizations. No funding was obtained for the study.

Smartphone-based system rivals clinical assessments of anxiety in bipolar disorder
In patients with bipolar disorder currently in partial or full remission, self-reporting of anxiety to a smartphone-based system matched clinical evaluations of anxiety, according to Maria Faurholt-Jepsen, MD, and her associates.
A total of 84 patients with bipolar disorder who participated in the randomized, controlled, single-blind, parallel-group MONARCA II trial were included in the study, reported Dr. Faurholt-Jepsen of Rigshospitalet in Copenhagen, and her associates. All patients reported their anxiety to the smartphone-based system every day for a 9-month period; all patients underwent clinical evaluations of anxiety, functioning, patient-reported stress, and quality of life at five fixed time points over the study period. The study was published online by the Journal of Affective Disorders.
Self-reported anxiety was mild, with 19.3% of patients reporting anxiety during the study period, and 2.6% reporting severe anxiety. No association was seen between gender and anxiety days, or between bipolar disorder type and anxiety days. Patients reported depressed mood on 43.2% of the days when anxiety was also reported, and reported mania on 48.0% of the days when anxiety was reported.
Self-reported anxiety scores were positively associated with the anxiety subitems on a key rating scale (P = .0001). In addition, self-reported anxiety was associated with perceived stress, quality of life, and functioning (P = .0001 for all three).
“ Frequent fine-grained monitoring in clinical, high-risk and epidemiological populations provides an opportunity to gain a better understanding of the nature, correlates, and clinical implications of [bipolar disorder],” the investigators wrote.
Three coauthors reported consulting with Eli Lilly, Astra Zeneca, Servier, Bristol-Myers Squibb, Lundbeck, Sunovion, and Medilink. Two coauthors are cofounders and shareholders in Monsenso.

Nerve transfer improves function after spinal cord injury
according to research published online July 4 ahead of print in the Lancet. Combining nerve transfer with tendon transfer may maximize the functional benefit of surgery.
The loss of upper extremity function after cervical spinal cord injury can reduce independence and social and vocational engagement. People with tetraplegia rank improvement in hand function as their most important goal. Tendon transfers have been the traditional method of restoring function, but interest in nerve transfers has been increasing with the publication of successful results. Nerve transfers can reanimate several muscles at once and require a smaller incision and shorter immobilization, compared with tendon transfers.
Injury had occurred less than 18 months previously
Natasha van Zyl, MBBS, a plastic and reconstructive surgeon at Austin Health in Melbourne, and colleagues conducted a prospective case series to examine the clinical and functional outcomes of nerve transfer surgery for the reanimation of upper limb function in patients with tetraplegia. The investigators also sought to compare these outcomes with published outcomes for tendon transfer surgery.
Between April 14, 2014, and Nov. 22, 2018, Dr. van Zyl and colleagues recruited consecutive patients of any age with early cervical spinal cord injury of motor level C5 and below. Injury was required to have occurred fewer than 18 months before enrollment. Eligible participants had been referred to a single center for upper extremity reanimation and were considered candidates for nerve transfer.
Every participant underwent single or multiple nerve transfers in one or both upper limbs, and some participants also underwent tendon transfers. The goal of surgery was the restoration of elbow extension, grasp, pinch, and hand opening. An independent assessor evaluated participants at baseline and at 12 months and 24 months after surgery. The primary outcome measures were the action research arm test (ARAT), the grasp release test (GRT), and the spinal cord independence measure (SCIM).
Grasp function improved significantly
Dr. van Zyl and colleagues recruited 16 participants with traumatic spinal cord injury who underwent 59 nerve transfers. Ten participants also underwent tendon transfers. The population’s mean age at time of injury was 27.3 years. Three patients were female. Motor vehicle accidents were the most common cause of injury (31%). Follow-up data at 24 months were unavailable for three patients.
Participants’ median ARAT total score significantly improved from 16.5 at baseline to 34.0 at 24 months. Median GRT total score significantly improved from 35.0 at baseline to 125.2 at 24 months. The population’s mean total SCIM score and mobility in the room and toilet SCIM score improved by more than the minimal detectable change and the minimal clinically important difference. The mean self-care SCIM score improved by more than the minimal detectable change between baseline and 24 months.
The researchers observed six adverse events related to the surgery, but none had sustained functional consequences. No patients had an increase in musculoskeletal or neuropathic pain. Four of the 50 nerve transfers with 24-month follow-up failed.
A novel technique
“This project is the first to comprehensively examine outcomes for early, multiple nerve transfer surgery in the upper limbs of people with tetraplegia following traumatic spinal cord injury and is the largest prospective series of nerve transfers reported in this population to date,” said Dr. van Zyl and colleagues. Study limitations included the small sample size, the high variability of spinal cord injury patterns, and the potential for the multiple procedures that each participant underwent to confound data analysis.
Future research could explore whether nerve transfers are beneficial at more than 24 months after spinal cord injury, wrote the authors. In addition, it is unclear whether function and strength continue to improve beyond 24 months after surgery.
The study was funded by the Institute for Safety, Compensation, and Recovery Research in Australia. The authors had no competing interests.

The data from van Zyl et al. suggest that nerve transfers restore more natural movement and finer motor control than tendon transfers do, said Elspeth J.R. Hill, MD, PhD, and Ida K. Fox, MD, plastic and reconstructive surgeons at Washington University in St. Louis, in an accompanying editorial. Patients can engage in light activity immediately after surgery, and cortical plasticity enables function to improve over time. Two disadvantages of nerve transfers, however, are that it takes months before new motion can be observed, and years before full strength can be regained.
The heterogeneity of cervical spinal cord injury requires an individualized approach to surgical assessment and management, they continued. Physicians and patients should make treatment decisions collaboratively. “We envisage a role for nerve transfers in settings where the intensive therapy and immobilization required to optimize complementary tendon transfers are unavailable,” wrote Dr. Hill and Dr. Fox.
Continuing research will be necessary to improve surgical technique and outcomes. “This research should include efforts to compare nerve transfer with tendon transfer, find the optimal timing of such surgeries, and determine which approach produces the greatest functional improvement,” they wrote. “Detailed study of the reasons for nerve transfer failure is also required, as is improving our understanding of the effects of biopsychosocial factors, including access to information and care, psychological readiness, and social support, on patient decision making and outcomes.”
Nerve transfers are a “huge advance” in the restoration of function after spinal cord injury, the authors added. “Surgeons who integrate nerve transfers into their spinal cord injury practice should take a careful and measured approach and rigorously study and disseminate their outcomes to advance this growing field,” they concluded.

Future research could explore whether nerve transfers are beneficial at more than 24 months after spinal cord injury, wrote the authors. In addition, it is unclear whether function and strength continue to improve beyond 24 months after surgery.
The study was funded by the Institute for Safety, Compensation, and Recovery Research in Australia. The authors had no competing interests.

Value-based metrics gain ground in physician employment contracts
Physician employment contracts increasingly include value- and quality-based metrics as bases for production bonuses, according to an analysis of recruitment searches from April 1, 2018, to March 31, 2019.
Metrics such as physician satisfaction rates, proper use of EHRs, following treatment protocols, and others that don’t directly measure volume are becoming more commonplace in employment contracts, though volume measures still are included, according to Phil Miller, vice president of communications at health care recruiting firm Merritt Hawkins and author of the company’s 2019 report on physician and advanced practitioner recruiting incentives, released July 8.
Of 70% of searches that offered a production bonus, 56% featured a bonus based at least in part on quality metrics, up from 43% in 2018. The finding represents the highest percent of contracts offering a quality-based bonus that the company has tracked, according to the report.
Merritt Hawkins’ review is based on a sample of the 3,131 permanent physician and advanced practitioner search assignments that Merritt Hawkins and its sister physician staffing companies at AMN Healthcare have ongoing or were engaged to conduct from April 1, 2018 to March 31, 2019.
Other common value-based metrics include reduction in hospital readmissions, cost containment, and proper coding.
While value-based incentives are on the rise, “facilities that employ physicians want to ensure they stay productive, and ‘productivity’ still is measured in part by what are essentially fee-for-service metrics, including relative value units [RVUs], net collections, and number of patients seen.”
RVUs were used in 70% of production formulas tracked in the 2019 review, up from 50% in the previous year and also a record high.
Mr. Miller noted that employers are seeking the “Goldilocks’ zone,” a balance point between traditional productivity measures and value-based metrics, very much a work in progress right now.
A possible corollary to the increase in production bonuses is a flattening of signing bonuses. During the current review period, 71% of contracts came with a signing bonus, up slightly from 70% in the previous year’s report and down from 76% 2 years ago.
Signing bonuses in the review period for the 2019 report averaged $32,692, down from $33,707 during the 2018 report’s review period.
Overall, family practice physicians remain the highest in demand for job searches, but specialty practice is gaining ground.
For the 2018-2019 review, family medicine was the most requested search by specialty, with 457 searches requested. While the ranking remains No. 1, as it has for the past 13 years, the number of searches has been on a steady decline. Last year, there were 497 searches, which was down from 607 2 years ago and 734 4 years ago.
Mr. Miller said there were a few reasons for the lower number of searches. “One is just the momentum shifts that are kind of inherent to recruiting. People put all of their resources into one area, typically, and in this case it was primary care and they realized, ‘Hey wait a minute, we need some specialists for these doctors to refer to, so now we have to put some of our chips in the specialty basket.’ ”
The Baby Boomers also is having an effect – as they age and are experiencing more health issues, more specialists are needed.
“[Older patients] visit the doctor twice or three times the rate of a younger person and they also generate a much higher percentage of inpatient procedures and tests and diagnoses,” he said.
On the opposite end of the spectrum, “younger people are less likely to have a primary care doctor who coordinates their care,” Mr. Miller said. “What they typically do is go to an urgent care center, a retail clinic, maybe even [use] telemedicine so they are not accessing the system in the same way or necessarily through the same provider.”
Demand for psychiatrists remained strong for the fourth year in a row, but the number of searches has declined for the last several years. For the current review period, there were 199 searches, down from 243 the previous year, 256 2 years ago, and 250 3 years ago.
There is “pretty much a crisis in behavioral health care now because there are so few psychiatrists and the demand has increased,” Mr. Miller noted.

Maternal migraine is associated with infant colic
PHILADELPHIA – , according to research presented at the annual meeting of the American Headache Society. Fathers with migraine are not more likely to have children with colic, however. These findings may have implications for the care of mothers with migraine and their children, said Amy Gelfand, MD, associate professor of neurology at the University of California, San Francisco.
Smaller studies have suggested associations between migraine and colic. To examine this relationship in a large, national sample, Dr. Gelfand and her research colleagues conducted a cross-sectional survey of biological parents of 4- to 8-week-olds in the United States. The researchers analyzed data from 1,419 participants – 827 mothers and 592 fathers – who completed online surveys in 2017 and 2018.
Parents provided information about their and their infants’ health. The investigators identified migraineurs using modified International Classification of Headache Disorders 3rd edition criteria and determined infant colic by response to the question, “Has your baby cried for at least 3 hours on at least 3 days in the last week?”
In all, 33.5% of the mothers had migraine or probable migraine, and 20.8% of the fathers had migraine or probable migraine. Maternal migraine was associated with increased odds of infant colic (odds ratio, 1.7). Among mothers with migraine and headache frequency of 15 or more days per month, the likelihood of having an infant with colic was even greater (OR, 2.5).
“The cause of colic is unknown, yet colic is common, and these frequent bouts of intense crying or fussiness can be particularly frustrating for parents, creating family stress and anxiety,” Dr. Gelfand said in a news release. “New moms who are armed with knowledge of the connection between their own history of migraine and infant colic can be better prepared for these often difficult first months of a baby and new mother’s journey.”

Noninvasive prenatal test may detect sickle cell disease
FORT LAUDERDALE, FLA. — Researchers have developed an assay that can be used in noninvasive prenatal testing (NIPT) of cell-free fetal DNA present in maternal blood to identify sickle cell disease without using paternal DNA, which could provide an alternative to other invasive methods, according to results of a pilot study.
The novel NIPT assay had a sensitivity greater than 98% and a specificity greater than 99% in early-phase analysis, Vivien A. Sheehan, MD, PhD, of Baylor College of Medicine, Houston, reported at the annual meeting of the Foundation for Sickle Cell Disease Research.
“Noninvasive prenatal testing is a safe and affordable alternative to chorionic villus sampling or amniocentesis and can be performed earlier in pregnancy,” Dr. Sheehan said. “There is a lot of potential for the growth of this test and its impact not only in this country, but worldwide.”
The NIPT uses cell-free fetal DNA from the pregnant mother’s peripheral blood.
“We know that fetal DNA is present in maternal blood and can comprise about 10% by the 10th week of gestation, and it increases as pregnancy progresses,” Dr. Sheehan said.
Maternal alleles from the baby and mother, as well as paternal alleles from the baby, can be identified in maternal blood. “By analyzing cell-free DNA in maternal blood via next-generation sequencing, we can determine fetal disease status,” she said.
Dr. Sheehan noted some reports have supported the use of NIPT for identifying trisomy and aneuploidy, but NIPT has encountered some challenges in identifying autosomal recessive disorders such as sickle cell disease.
To accomplish this, researchers at Baylor and test developer BillionToOne, developed a novel sequencing-based molecular counting strategy that can help measure the ratio of mutant versus normal alleles, Dr. Sheehan said.
The results obtained to date indicate that the assay reliably detects fetal sickle cell disease status when the fetal fraction is as low as 5%, the same limit as aneuploidy NIPT.
The method uses a commercial DNA extraction kit to isolate and purify cell-free fetal DNA from a single blood draw, then performs sickle cell disease NIPT assays using proprietary reagents, Dr. Sheehan explained. The protocol includes bioinformatic analyses that are used to determine hemoglobin S (HbS) mutation ratio and fetal disease status.
The pilot study had two phases. In the first phase, which has been completed, researchers sought to optimize the beta-globin gene probes using cell-free fetal DNA from compound heterozygote patients with sickle cell disease to establish the expected ratio of HbS mutation.
In the second phase, the researchers validated the test on pregnant women with sickle cell trait or sickle cell disease by performing the assay in maternal samples collected between 10-35 weeks of gestation.
Among the six controls who have sickle cell trait, the NIPT reported no false positives when compared with the state newborn screen results, Dr. Sheehan said. For the one participant with sickle cell anemia, the NIPT and newborn screening concurred on two blood draws, but the NIPT was inconclusive on the first blood draw obtained at 10 weeks’ gestation because of low levels of cell-free fetal DNA.
Overall, the analysis showed an analytical sensitivity greater than 98% and a specificity greater than 99%, even in the absence of paternal DNA, the study found.
BillionToOne developed the test. Dr. Sheehan reported having no financial relationships to disclose.

Cellulitis ranks as top reason for skin-related pediatric inpatient admissions
AUSTIN, TEX. – showed.
“Skin conditions significantly affect pediatric inpatients, and dermatologists ought be accessible for consultation to enhance care and costs,” the study’s first author, Marcus L. Elias, said in an interview prior to the annual meeting of the Society for Pediatric Dermatology.
According to Mr. Elias, who is a 4th-year medical student at Rutgers New Jersey Medical School–Newark, few national studies on skin diseases for pediatric inpatients have been published in the medical literature. Earlier this year, researchers examined inpatient dermatologic conditions in patients aged 18 years and older (J Am Acad Dermatol 2019;80[2]:425-32), but Mr. Elias and associates set out to analyze the burden of inpatient pediatric dermatologic conditions on a national basis. “We wanted to see if the same conditions that were hospitalizing adults were also hospitalizing kids,” he said. “We found that this was indeed the case.”
The researchers queried the National Inpatient Sample database for all cases involving patients aged 18 years and younger during 2001-2013. The search yielded a sample of 16,837,857 patients. From this, the researchers analyzed diagnosis-related groups for dermatologic conditions denoting the principal diagnosis at discharge, which left a final sample of 84,090 patients. Frequency and chi-squared tests were used to analyze categorical variables.
More than half of patients (54%) were male, 36% were white, 48% had Medicaid insurance, and 43% had private insurance. Mr. Elias reported that the median length of stay for patients was 2 days and the median cost of care was $6,289.50 for each case. More than three-quarters of pediatric inpatients with dermatologic diagnoses were treated for “cellulitis” (66,147 cases, or 79%), with most cases involving the legs (16,875 cases, or 20%). Other pediatric inpatients were admitted for “minor skin disorder without complications” (5,458 cases, or 7%), and “minor skin disorder with complications” (2,822 cases, or 3%). A total of 64 patients died during the study period. Of these, 31 cases (50%) involved “skin graft and/or debridement of skin ulcer or cellulitis without complications,” the study found.
“We were surprised that the major cause of mortality for our patients was classified as ‘skin graft and/or debridement of skin ulcer or cellulitis without complications,’ as a similar diagnosis-related groupings exist denoting that complications did arise,” Mr. Elias said. “Still, it is not possible for us to determine if the mortality was from the skin graft/debridement or another cause entirely. It is possible that the procedure was without complications, only to have the patient succumb to an ancillary process.”
He acknowledged certain limitations of the study, including the fact that the function of dermatologic consults for hospitalized patients was not examined. “We also cannot draw conclusions as to whether improved outpatient therapy reduces the need for hospitalization,” he said. Mr. Elias reported having no financial disclosures.

“We were surprised that the major cause of mortality for our patients was classified as ‘skin graft and/or debridement of skin ulcer or cellulitis without complications,’ as a similar diagnosis-related groupings exist denoting that complications did arise,” Mr. Elias said. “Still, it is not possible for us to determine if the mortality was from the skin graft/debridement or another cause entirely. It is possible that the procedure was without complications, only to have the patient succumb to an ancillary process.”

“Skin conditions significantly affect pediatric inpatients, and dermatologists ought be accessible for consultation to enhance care and costs,” the study’s first author, Marcus L. Elias, said in an interview prior to the annual meeting of the Society for Pediatric Dermatology.
According to Mr. Elias, who is a 4th-year medical student at Rutgers New Jersey Medical School–Newark, few national studies on skin diseases for pediatric inpatients have been published in the medical literature. Earlier this year, researchers examined inpatient dermatologic conditions in patients aged 18 years and older (J Am Acad Dermatol 2019;80[2]:425-32), but Mr. Elias and associates set out to analyze the burden of inpatient pediatric dermatologic conditions on a national basis. “We wanted to see if the same conditions that were hospitalizing adults were also hospitalizing kids,” he said. “We found that this was indeed the case.”
The researchers queried the National Inpatient Sample database for all cases involving patients aged 18 years and younger during 2001-2013. The search yielded a sample of 16,837,857 patients. From this, the researchers analyzed diagnosis-related groups for dermatologic conditions denoting the principal diagnosis at discharge, which left a final sample of 84,090 patients. Frequency and chi-squared tests were used to analyze categorical variables.
More than half of patients (54%) were male, 36% were white, 48% had Medicaid insurance, and 43% had private insurance. Mr. Elias reported that the median length of stay for patients was 2 days and the median cost of care was $6,289.50 for each case. More than three-quarters of pediatric inpatients with dermatologic diagnoses were treated for “cellulitis” (66,147 cases, or 79%), with most cases involving the legs (16,875 cases, or 20%). Other pediatric inpatients were admitted for “minor skin disorder without complications” (5,458 cases, or 7%), and “minor skin disorder with complications” (2,822 cases, or 3%). A total of 64 patients died during the study period. Of these, 31 cases (50%) involved “skin graft and/or debridement of skin ulcer or cellulitis without complications,” the study found.

Neonatal ICU stay found ‘protective’ against risk for developing atopic dermatitis
AUSTIN – The
“While more time in the NICU is associated with a lesser risk of developing atopic dermatitis, we certainly do not want to keep infants in the NICU longer in order to lower their risk of atopic dermatitis,” the study’s first author, Jennifer J. Schoch, MD, said in an interview prior to the annual meeting of the Society for Pediatric Dermatology. “Instead, we need to work on understanding the mechanisms behind this relationship. For example, are there certain exposures in the NICU that influence the cutaneous immunity to ultimately reduce the risk of atopic dermatitis?”
According to Dr. Schoch, a pediatric dermatologist at the University of Florida, Gainesville, the medical literature has been conflicted regarding the relationship between prematurity and eczema. A recent meta-analysis of 18 studies found an association between very preterm birth and a decreased risk of eczema, yet the risk became insignificant among children born moderately preterm (J Am Acad Dermatol. 2018;78[6]:1142-8). However, the factors contributing to this relationship are not well understood.
In an effort to explore the infant, maternal, and environmental factors of infants who developed AD, compared with infants who did not, Dr. Schoch and colleagues evaluated infants who were born at University of Florida Health from June 1, 2011, to April 30, 2017; had at least two well-child visits; and had at least one visit at 300 days old or later. The researchers included 4,016 mother-infant dyads in the study. Atopic dermatitis was diagnosed in 26.5% of the infants. Factors significantly associated with the incidence of AD were delivery mode (P = .0127), NICU stay (P = .0001), gestational age (P = .0006), and birth weight (P = .0020). Specifically, infants had a higher risk of developing AD if they were delivered vaginally, did not stay in the NICU, had a higher gestational age, or had a higher birth weight. Extremely preterm (less than 28 weeks’ gestation) and very preterm (28 to less than 32 weeks’ gestation) infants had the lowest rates of AD, at 10.9% and 19%, respectively.
When the researchers adjusted for other variables to their model, only length of stay in the NICU was related to the development of AD. Specifically, infants who spent more time in the NICU had a lower risk of developing atopic dermatitis (P = .0039).
“We were surprised to find that the length of stay in the neonatal intensive care unit was the strongest protective factor against the future development of eczema,” Dr. Schoch said. “Instead of this relationship being mediated by gestational age or birth weight, it was how much time the infants spent in the NICU that seemed to ‘protect’ from future eczema.”
She acknowledged certain limitations of the study, including its retrospective design with data gathered from electronic medical records. Also, “diagnosis was determined by ICD-9 or ICD-10 code, and not confirmed by dermatologists,” she said.
In their abstract, the researchers wrote that the finding highlights “the importance of early life interactions between the microbiome, developing cutaneous immunity, and the evolving skin barrier of the preterm infant. The skin microbiome of premature infants differs from full-term infants, in that the premature infant cutaneous microbiome is dominated by Staphylococcus species” (Microbiome. 2018;6[1]:98). They added that “the early presence of Staphylococcus on the skin may confer protection.”

Migraine comorbidities rise with increased headache days
PHILADELPHIA – The more days per month a person reported experiencing migraine headaches the greater their prevalence of various comorbidities associated with migraine headaches, including insomnia, depression, anxiety, and gastric ulcer disease, according to results from a survey of more than 92,000 U.S. residents.
“Increasing monthly headache day [MHD] frequency was associated with an increased risk of other health conditions in people with migraine,” Richard B. Lipton, MD, and his associates reported in a poster at the annual meeting of the American Headache Society. “The findings may be due to direct causality, reverse causality, shared risk factors, or detection bias.”
Additional analysis of the association with gastric ulcer disease (GUD) showed that it also linked with the number of days per month when a person with migraine used an NSAID. Migraineurs who self-reported having GUD averaged 10.5 days a month using an NSAID, compared with an average NSAID usage of just over 6 days a month among migraineurs without GUD, Dr. Lipton, a professor and vice-chair of neurology at Albert Einstein College of Medicine, New York, reported in a separate poster at the meeting.
The Migraine in America Symptoms and Treatment (MAST) study enrolled more than 90,000 U.S. residents starting in 2016. Using a validated diagnostic screening tool, the MAST researchers identified 15,133 of these people as having at least one day with a migraine headache during the 3 months prior to the survey and 77,453 who reported no migraine history (Headache. 2018 Oct;58[9]: 1408-26). The people with migraine averaged 43 years old, compared with an average of 52 years for those without migraine; 73% of the migraineurs were women.
Analysis of the prevalence of various self-reported, physician-diagnosed comorbidities showed a strong correlation between the relative odds of having a comorbidity and the self-reported number of MHDs. For example, the odds ratio for having insomnia, compared with the people without migraine, was nearly 200% among people reporting 1-4 MHDs, more than 300% higher among those reporting 5-9 MHDs, 500% higher with MHDs of 10-14, and nearly 700% higher among people reporting 20 or more MHDs. The researchers saw roughly similar patterns of rising comorbidity prevalence with higher numbers of MHDs for depression, anxiety, and GUD. The prevalence of a history of stroke or transient ischemic attack also increased with increasing numbers of MHDs but less steeply than for the other comorbidities. And while the prevalence of peripheral artery disease and epilepsy was consistently more than 100% greater among the migraineurs, compared with those with no recent migraine history, the prevalence of each of these two comorbidities showed no clear pattern of increasing prevalence as MHDs increased.
The analysis looked specifically at the relationship between GUD and NSAID use among people reporting migraine. Overall, the migraineurs had a greater than 200% increased prevalence of GUD than those without migraine. The odds ratio for GUD among migraineurs with 1-4 MHDs was 2.6, compared with those without migraine, and the odds ratio steadily rose with increasing MHDs to a peak of 490% higher among those who averaged 21 or more MHDs.
This link between the number of MHDs and prevalence of GUD may have some relationship to oral NSAID use, as overall NSAID use was higher among people with recent migraines than in those without migraines. However, the number of days per month of oral NSAID use appeared to plateau at an average of about 19 days once people reported having at least 10 MHDs, the researchers said. Even when people reported having more than twice as many MHDs their NSAID use remained at an average of about 19 days per month.
MAST was sponsored by Dr. Reddy’s Laboratories. Dr. Lipton had been a consultant to Dr. Reddy’s and to several other companies.
