Neonatal Sweet syndrome with associated rectovestibular fistula and review of the literature.

An otherwise healthy 4-week-old term female of Japanese heritage presented with a 1-week history of asymptomatic progressive, generalized skin lesions. The lesion morphology, distribution, and dermatopathology result was consistent with Sweet syndrome. The patient was found to have a congenital type H rectovestibular fistula. This case highlights the rare association of rectovestibular fistula in neonatal Sweet syndrome which has only been described in neonates of Japanese heritage.

A case of erythema ab igne with histopathological features resembling keratosis lichenoides chronica.

This case describes a pediatric patient with a history of ichthyosis vulgaris and global anhidrosis who was diagnosed with erythema ab igne (EAI), a rare dermatosis resulting from chronic heat exposure. After developing progressive, reticulated brown patches on his extremities and abdomen, extensive diagnostic investigations were conducted to rule out autoimmune, vascular, and genetic etiologies. Bloodwork was unrevealing and biopsies showed histologic features closely resembling keratosis lichenoides chronica. Ultimately, after discovering the patient had prolonged exposure to a space heater, the diagnosis of EAI was made. This case underscores the diagnostic challenges in pediatric EAI cases and emphasizes the importance of careful history taking as part of a comprehensive evaluation.

Patients with Limited Life Expectancy Are Biopsied for Keratinocyte Cancers at Similar Frequency to Healthy Patients.

BACKGROUND: In many fields of medicine, guidelines recommend reduced cancer screening in patients of advanced age with limited life expectancy (LLE). In dermatology, there are currently no guidelines for adjusted evaluation and management practices of keratinocyte cancer (KC) in patients with LLE. Little is known regarding evaluation and management patterns and frequency of biopsies in these patients. OBJECTIVE: We sought to determine if dermatology providers biopsy LLE patients with similar frequency to their age-matched peers and quantify frequency of associated complications. METHODS: This was a retrospective cohort study of evaluations for skin cancer quantified by skin biopsy frequency at the North Texas Veterans Affairs Health System dermatology clinic for 3,062 patients between 2005 and 2009, including a 5-year follow-up period. Life expectancy was quantified by the validated Charlson Comorbidity Index (CCI) with a Deyo adaptation. RESULTS: There was no significant difference in biopsy frequency of KC in LLE versus non-LLE patients in most age-controlled groups, with increased biopsy frequency in LLE patients in the 65-74 age category (p = 0.02). There was also an increased risk of complications from biopsy in the 75-84 (many comorbidities subgroup: RR = 3.27, p = 0.002; some comorbidities subgroup: RR = 2.26, p = 0.048) and 65-74 (many comorbidities subgroup: RR = 1.52, p = 0.004) age groups when compared to age-matched healthy controls. CONCLUSION: Biopsy frequency is similar or increased in patients with LLE compared with age-matched controls, with increased frequency of complications. Further studies are needed to understand the underlying factors driving these practice patterns.

Scoping review of medical students' perceptions of the field of dermatology.

Background: Although perceived barriers to applying to dermatology have been researched among medical students, there remains a dearth of literature dedicated to understanding perceptions that medical students have of the field of dermatology and dermatologists. Methods: A review of the literature in Embase, Pubmed, Scopus, Web of Science, and ScienceDirect were carried out to identify articles and abstracts between 2016 and 2021 relating to medical student perceptions of the field of dermatology. Peer-reviewed English studies measuring attitudes/level of interest in dermatology or other specialities, understanding of dermatologic topics, procedures, and/or scope of practice were included. Duplicate studies and conference abstracts were excluded. All publications were screened using the PRISMA-Sc guidelines. Findings were summarised and tabulated accordingly. Results: A total of nine articles met inclusion criteria and eight are included in this review since one was not accessible online. Notable findings include non-US medical students perceiving dermatology as monotonous, stigmatized, unfamiliar, and difficult to access with a misunderstanding of the diversity and severity of the conditions dermatologists treat. No data on US medical student perceptions was found. Perceptions were found to be influential in career planning: medical students may reject specialities after exposure to negative comments on the field. Factors attracting students to dermatology include the appeal of being a dermatologist, media portrayal, and dermatologists' influence on patients' lives. Completion of dermatology-related activities improved medical student interest, comfort, and understanding of the field. Early dermatology exposure in US undergraduate premedical students led to heightened interest in the field, more confidence in ability to find dermatology mentors, and increased perception that dermatology serves the needs of underserved communities. Conclusions: This review demonstrates the need to further investigate medical student perceptions of dermatology, particularly in the United States. Perceptions of medical specialities can impact medical student career choices. Understanding which misconceptions may be preventing students from exploring dermatology can inform efforts towards improving diversity, equity, and inclusion: translating to an equitable match and improving patient outcomes. Limitations include exclusion of articles published before 2016, geographic variability in studies, and limited data on evolving student perceptions over time.

Key Attributes of a Medical Learning Community Mentor at One Medical School: The Mentee Perspective.

To assess the elements necessary to be a successful learning community (ClinCalc) mentor to medical students from the mentee's perspective. Few such studies have utilized the in-depth and richness of detail obtained in qualitative studies. This qualitative study analyzed four focus group discussions lasting 45-90 min conducted at the University of Texas Southwestern Medical School, which has an established LC, in the year 2018. The groups included 14 pre-clerkship and 8 clerkship students. Investigators evaluated transcriptions of the focus group discussions using ATLAS.ti software. Three overarching categories of discussion emerged from the group discussions: (1) Relationship Competence, (2) Teaching Competence, and (3) Ethical and Compassionate Medical Practice Competence. Relationship Competence themes included "walk with me," relationship is most important, and one-on-one. Teaching Competence themes included above and beyond, recognize and address mentor limitations, and safe and enriching environment. Ethical and Compassionate Medical Practice Competence themes included ethical decision making and compassionate care for diverse patient populations. Mentees focused on various aspects of the mentor-mentee relationship as the single most essential competence. Themes mentees discussed as important qualities of a successful mentor may denote qualities to be prioritized in faculty development and mentor recruitment. Future studies could investigate how the LC environment informs former medical students and promotes patient outcomes.

Gene Expression Signatures in Inflammatory and Sclerotic Morphea Skin and Sera Distinguish Morphea from Systemic Sclerosis.

Morphea is an inflammatory fibrotic disorder of the skin that has been likened to systemic sclerosis (SSc). We sought to examine the molecular landscape of morphea by examining lesional skin gene expression and blood biomarkers and comparing the gene expression profiles with those from site-matched nonlesional and SSc lesional skin. We found the morphea transcriptome is dominated by IFN-γ-mediated T helper 1 immune dysregulation, with a relative paucity of fibrosis pathways. Specifically, expression profiles of morphea skin clustered with the SSc inflammatory subset and were distinct from the those of SSc fibroproliferative subset. Unaffected morphea skin also differed from unaffected SSc skin because it did not exhibit pathological gene expression signatures. Examination of downstream IFN-γ-mediated chemokines, CXCL9 and CXCL10, revealed increased transcription in the skin but not in circulation. In contrast to transcriptional activity, CXCL9 was elevated in serum and was associated with active, widespread cutaneous involvement. Taken together, these results indicate that morphea is a skin-directed process characterized by T helper 1 immune-mediated dysregulation, which contrasts with fibrotic signatures and systemic transcriptional changes associated with SSc. The similarity between morphea and the inflammatory subset of SSc on transcriptional profiling indicates that therapies under development for this subset of SSc are also promising for treatment of morphea.

Utilizing UVA-1 Phototherapy.

There is a long history of utilization of phototherapy for treatment of skin conditions. Because of its longer wavelength, UVA1 phototherapy is able to penetrate into the dermis and subcutis. This depth of penetration, combined with its unique immunomodulating properties, makes UVA1 an effective treatment modality for many immune-mediated skin diseases. In some cases, it performs better than other types of phototherapy.
