Cutaneous Manifestations of Nutritional Deficiencies in the Context of Food Deserts of United States.
Food deserts exist due to a multitude of factors ranging from socioeconomic status, racial disparities, geography, cost, and healthful food access. Given the vast biological function of vitamins and minerals, the clinical presentation for nutritional deficiencies ranges from benign to life-threatening. Often, the first indicators of underlying nutritional deficiencies are cutaneous manifestations. The first patient case is a 36-year-old female at 25 weeks gestation with a pruritic and painful rash that began in the genital region and spread centrifugally to her legs. The second patient case is a 42-year-old male with a pruritic rash that began at his abdomen and progressed to his thighs. The third patient case is a 48-year-old female with scattered lower extremity ecchymoses in different healing stages and scattered perifollicular erythema with corkscrew hairs. All three patients were found to have nutritional deficiencies and lived in identified food deserts. Deficiencies of zinc, vitamin A, thiamine, pyridoxine, and vitamin C and their subsequent cutaneous manifestations have scarce documentation within food deserts. These cases provide further insight into nutritional deficiencies and offer an opportunity for providers to identify patients at risk. To promote wellness, patients suffering from food insecurity must be identified efficiently and connected with essential resources
Loose Anagen Syndrome: A Retrospective Chart Review of 37 Cases.
BACKGROUND/OBJECTIVES: Loose anagen syndrome (LAS) is a disorder of abnormal anchorage of the hair to the scalp. Its symptoms include an inability to grow hair long and hair that is easily pulled out.
METHODS: We conducted a retrospective chart review of patients with LAS over the last 10 years at the Children\u27s Hospital of Philadelphia and found 37 cases.
RESULTS: LAS was more common in females and was found in all hair colors and skin types.
CONCLUSION: Diagnosis of LAS should be made based on history, microscopic findings, and hair bulb and shaft features
A Review of the Use of Biotin for Hair Loss.
BACKGROUND: Biotin has gained commercial popularity for its claimed benefits on healthy hair and nail growth. Despite its reputation, there is limited research to support the utility of biotin in healthy individuals.
OBJECTIVE: To systematically review the literature on biotin efficacy in hair and nail growth.
METHODS: We conducted a PubMed search of all case reports and randomized clinical trials (RCTs) using the following terms: (biotin and hair); (biotin and supplementation and hair); (biotin supplementation); (biotin and alopecia); (biotin and nails); (biotin and dermatology), and (biotin recommendations).
RESULTS: We found 18 reported cases of biotin use for hair and nail changes. In all cases, patients receiving biotin supplementation had an underlying pathology for poor hair or nail growth. All cases showed evidence of clinical improvement after receiving biotin.
CONCLUSIONS: Though its use as a hair and nail growth supplement is prevalent, research demonstrating the efficacy of biotin is limited. In cases of acquired and inherited causes of biotin deficiency as well as pathologies, such as brittle nail syndrome or uncombable hair, biotin supplementation may be of benefit. However, we propose these cases are uncommon and that there is lack of sufficient evidence for supplementation in healthy individuals
Evaluating Dermatology Residents Combined Oral Contraceptive Pill Prescribing Practices, Knowledge Base, and Comfort Level in the Management of Acne Vulgaris
The preadolescent acne microbiome: A prospective, randomized, pilot study investigating characterization and effects of acne therapy.
BACKGROUND/OBJECTIVES: Acne, a common pediatric disease, tends to be more comedonal in preadolescents, whereas older individuals are more likely to have inflammatory lesions in addition to comedones. Thus the microbiome of preadolescents may be different. In this pilot study we aimed to characterize the preadolescent acne microbiome, compare the microbiome in preadolescents with and without acne, and investigate changes in the microbiome after topical treatment with benzoyl peroxide or a retinoid in a small cohort of preadolescents.
METHODS: Participants were 7-10 years of age with (intervention group) or without (control group) acne and were recruited during routine outpatient dermatology visits. Baseline questionnaires, physical examination, and pore strip application were performed for all participants. Intervention group participants were randomized to receive topical therapy with benzoyl peroxide 5% gel or cream or tretinoin 0.025% cream. Participants with acne were followed up 8-10 weeks later and pore strip application was repeated.
RESULTS: Preadolescents with acne were colonized with a greater diversity of cutaneous bacteria than controls and the most commonly identified bacterium was Streptococcus. The number of bacterial species and phylogenetic diversity decreased after treatment with benzoyl peroxide and tretinoin.
CONCLUSION: The predominant bacteria in microbiome studies of adult acne is Propionibacterium, whereas in this pediatric population we saw a lot of Streptococcus bacteria. After treatment, the microbiomes of intervention group participants more closely resembled those of control group participants
Sexual orientation and gender identity (SOGI) data in dermatologic studies and opportunities for inclusion.
Dermatologists serve a vast array of patients with unique backgrounds. The National Institutes of Health (NIH) designated members of sexual and gender minorities as underrepresented in scholarly literature. Our study examines the past 10 years of studies published in highly-cited dermatologic journals, surveying each study for common data collection of sexual orientation and gender identity (SOGI) in dermatological studies. We found representation of sexual and gender minorities to be increasing in dermatological studies but recommend that SOGI data be collected regularly just as any other common variable in dermatological patient studies
