Updates on disorders in curly hair.

Hair disorders, including central centrifugal cicatricial alopecia (CCCA), traction alopecia (TA), and acquired trichorrhexis nodosa (ATN), commonly occur in individuals with curly textured hair. Curly textured hair in individuals of African descent has unique properties and can present diagnostic and therapeutic challenges. CCCA has been linked to uterine leiomyoma and type 2 diabetes mellitus, as well as fibroproliferation. TA often presents with a fringe sign and can arise from high-tension hairstyles presumed to be protective. Trichoscopy is useful in establishing a diagnosis; perifollicular halos are more commonly seen than perifollicular erythema or scale in CCCA. In TA, miniaturized follicles, hair casts, and "flambeau sign" can be seen. Hairstyling practices likely contribute to TA and ATN; however, the data are mixed on the role of chemical relaxers and heat styling in CCCA. Unique considerations in the presentation of frontal fibrosing alopecia in curly textured hair have also been published recently. This review provides a comprehensive, up-to-date summary of these disorders with an emphasis on their unique properties, as well as considerations in hair care for curly textured hair.

No-shows to hidradenitis suppurativa clinic visits: Patient perspectives.

Background: Hidradenitis suppurativa (HS) is a debilitating chronic inflammatory skin condition that typically requires consistent care. Contributory factors to why patients with HS miss their clinic appointments have not been investigated. Objectives: This article seeks to characterise reasons that HS patients do not keep their appointments and identify strategies to minimise no-show rates and improve delivery of care to HS patients. Methods: An anonymous survey was distributed to online HS support groups. Results: Of the 254 respondents, 18.9% reported ever missing an appointment for HS. Common reasons for missing an appointment include: patient was experiencing an HS flare (72.9%), prior poor experience with a healthcare provider (54.2%) or healthcare staff member (37.5%), embarrassment of condition (41.7%), and distrust that the appointment would help with management of HS (39.6%). Respondents who were non-White, who were disabled, or who had lower socioeconomic status were more likely to have missed an appointment (p < 0.05). Conclusions: This study highlights areas where dermatologists may help improve appointment attendance, including encouraging patients to seek care during flares and striving to optimise the patient experience.

Calcipotriene/Betamethasone Dipropionate Foam as a Potential Safe and Effective Treatment of Nail Psoriasis.

Background: Nail psoriasis is a common condition that affects quality of life in individuals with psoriasis and psoriatic arthritis. Topical treatments have been shown to be effective in treating nail bed disease but not as effective in treating nail matrix diseases, which often requires intralesional corticosteroids. Objectives: The objective of this open-label study was to evaluate the efficacy of combination calcipotriol/betamethasone dipropionate foam as a treatment for nail psoriasis including nail matrix disease. Method: We report three patients with moderate to severe nail psoriasis with involvement of all ten fingernails who applied study foam nightly for 6 months. Nails were assessed using the NAPSI score evaluating both nail bed and nail matrix disease. Results: NAPSI score improved including nail matrix disease in the majority of nails. No skin irritation or unexpected adverse events occurred. Conclusions: We conclude this foam combination product could be an effective and safe treatment for fingernail psoriasis and may provide better nail matrix penetration as evidenced by improvement in nail matrix score. Further studies are needed for additional evaluation.

Treatment for central centrifugal cicatricial alopecia-Delphi consensus recommendations.

BACKGROUND: There is no established standard of care for treating central centrifugal cicatricial alopecia (CCCA), and treatment approaches vary widely. OBJECTIVE: To develop consensus statements regarding the use of various pharmacological therapies in treating adults with CCCA. METHODS: We invited 27 dermatologists with expertise in hair and scalp disorders to participate in a 3-round modified Delphi study between January and March 2023. Statements met strong consensus if 75% of respondents agreed or disagreed. Statements met moderate consensus if 55% or more but less than 75% agreed or disagreed. RESULTS: In round 1, 5 of 33 (15.2%) statements met strong consensus, followed by 9 of 28 (32.1%) in round 2. After the final round 3 meeting, strong consensus was reached for 20 of 70 (28.6%) overall statements. Two statements achieved moderate consensus. LIMITATIONS: This study included only English-speaking, US-based dermatologists and did not consider nonpharmacological therapies. CONCLUSION: Despite varying opinions among dermatologists, consensus was reached for several statements to help clinicians manage CCCA. We also highlight areas that lack expert consensus with the goal of advancing research and therapeutic options for CCCA.

Clinical Outcomes for Uptitration of Baricitinib Therapy in Patients With Severe Alopecia Areata: A Pooled Analysis of the BRAVE-AA1 and BRAVE-AA2 Trials.

Importance: Baricitinib is an oral selective Janus kinase 1/2 inhibitor that has achieved clinically meaningful outcomes for scalp, eyebrow, and eyelash hair regrowth in patients with severe alopecia areata (AA) at week 36 of treatment. Treatment with baricitinib, 4 mg, has resulted in higher response rates than baricitinib, 2 mg, at weeks 36 and 52. Objective: To determine the efficacy of uptitration to baricitinib, 4 mg, for 24 weeks in patients who had previously not responded to baricitinib, 2 mg (Severity of Alopecia Tool [SALT] score of >20). Design, Setting, and Participants: BRAVE-AA1 and BRAVE-AA2 are multicenter, placebo-controlled, phase 3 randomized clinical trials that were initiated on September 24, 2018, and July 8, 2019, respectively, with follow-up to 200 weeks (data cutoffs of November 11, 2021, and November 5, 2021, respectively). This pooled analysis reports long-term extension data up to week 76. At baseline, 1200 adult patients with severe AA (SALT score ≥50) were randomly assigned in a 3:2:2 ratio to receive baricitinib, 4 mg; baricitinib, 2 mg; or placebo. Patients treated with baricitinib remained on the same treatment dose until week 52. Patients were considered nonresponders to baricitinib, 2 mg, if they had a SALT score greater than 20 after 52 weeks of therapy. Main Outcomes and Measures: The proportions of patients achieving a SALT score of 20 or lower and clinician-reported outcome for eyebrow hair loss and eyelash hair loss scores of 0 or 1 (full coverage or minimal gaps) with 2-point or higher improvements from baseline (among those with baseline scores ≥2 [significant gaps to no notable hair]) were analyzed through week 76. Results: At week 52, of the 340 patients (mean [SD] age, 38.4 [12.9] years; 212 [62.4%] female) treated with baricitinib, 2 mg, 212 (62.4%) had a SALT score higher than 20 and were uptitrated to baricitinib, 4 mg. Two-thirds of these patients (142 of 212 [67.0%]) had a baseline SALT score of 95 to 100, indicating very severe AA. At week 76, 55 of the 212 patients (25.9%) had achieved a SALT score of 20 or lower. During the same period, response rates for clinician-reported outcome scores of 0 or 1 increased from 19.3% (31 of 161 patients) to 37.9% (61 of 161 patients) for eyebrows and from 24.1% (33 of 137 patients) to 40.9% (56 of 137 patients) for eyelashes. Conclusions and Relevance: In this pooled analysis of the BRAVE-AA1 and BRAVE-AA2 trials, uptitration of baricitinib, 2 mg, to baricitinib, 4 mg, in those who did not respond to the 2-mg dose resulted in meaningful improvement of response rates over the subsequent 24 weeks for scalp, eyebrow, and eyelash hair loss. Trial Registration: ClinicalTrials.gov Identifiers: NCT03570749 and NCT03899259.

Interacting With Dermatology Patients Online: Private Practice vs Academic Institute Website Content.

Although both private practices and academic institutions in dermatology treat the same variety of pathologies, private practices entice more patients. The purpose of this study was to examine the differences in website content between dermatology private practices and academic institutions. All 140 dermatology residency programs were first queried. Only websites that contained pertinent information for patients were used in this study (113 of 140 programs). A total of 113 private practice websites were then matched for location and reputation. These sites were assessed for 23 content criteria categorized as practice, physician, patient, or treatment/procedure. The results may be useful for optimizing both private practice and academic institution websites so that patients can better understand the institutions that provide their care.

Hidradenitis Suppurativa and Five Key Vitamins and Minerals.

Hidradenitis suppurativa (HS), a chronic inflammatory disease characterized by painful abscesses and nodules, has limited effective treatment options. However, adjuncts to standard therapeutics such as dietary modifications have been increasingly investigated in recent years. This comprehensive review aimed to analyze the literature concerning the relationship between HS and 28 essential vitamins and minerals. A literature search was performed via PubMed, Embase, Ovid, and Scopus using search terms related to HS and the essential vitamins and minerals. A total of 215 unique articles were identified and analyzed. Twelve essential nutrients had documented associations with HS; definitive supplementation or monitoring recommendations were identified for 7 of the 12 HS-associated nutrients in the literature. Evidence is growing that supports adjunct supplementation of zinc, vitamin A, and vitamin D in the treatment of HS. Further, obtaining serum levels of zinc, vitamin A, vitamin D, and vitamin B12 upon initial diagnosis of HS may be beneficial to optimize standard HS treatment. In conclusion, optimizing nutrition in addition to standard HS therapeutics may help reduce disease burden; however more research is needed.

Mechanism underlying follicular hyperproliferation and oncogenesis in hidradenitis suppurativa.

Hidradenitis suppurativa (HS) is a skin disorder that causes chronic painful inflammation and hyperproliferation, often with the comorbidity of invasive keratoacanthoma (KA). Our research, employing high-resolution immunofluorescence and data science approaches together with confirmatory molecular analysis, has identified that the 5'-cap-dependent protein translation regulatory complex eIF4F is a key factor in the development of HS and is responsible for regulating follicular hyperproliferation. Specifically, eIF4F translational targets, Cyclin D1 and c-MYC, orchestrate the development of HS-associated KA. Although eIF4F and p-eIF4E are contiguous throughout HS lesions, Cyclin D1 and c-MYC have unique spatial localization and functions. The keratin-filled crater of KA is formed by nuclear c-MYC-induced differentiation of epithelial cells, whereas the co-localization of c-MYC and Cyclin D1 provides oncogenic transformation by activating RAS, PI3K, and ERK pathways. In sum, we have revealed a novel mechanism underlying HS pathogenesis of follicular hyperproliferation and the development of HS-associated invasive KA.

Needs and Gaps in Resident Trainee Education, Clinical Patient Care, and Clinical Research in Cosmetic Dermatology: Position Statement of the Association of Academic Cosmetic Dermatology.

Cosmetic dermatology is a key subspecialty of academic dermatology. As such, academic centers are expected to demonstrate excellence in the teaching of cosmetic dermatology skills to trainees, the clinical delivery of cosmetic dermatology services to patients, and the performance of clinical research that advances knowledge and uncovers new therapies in cosmetic dermatology. The Association of Academic Cosmetic Dermatology (AACD), a newly formed medical professional society, includes as its principal aims the support of all of these areas. AACD is comprised of group of board-certified dermatologists who teach cosmetic and laser dermatology at US dermatology residency programs. An expert panel constituted by the AACD recently convened a workshop to review gaps pertaining to academic cosmetic dermatology. This panel considered needs and potential corrective initiatives in three domains: resident education, patient experience, and clinical research. The work of the panel was used to develop a roadmap, which was adopted by consensus, and which will serve to guide the AACD moving forward.

Quantitative analysis of restricted metals and metalloids in tattoo inks: A systematic review and meta-analysis.

The various ingredients and impurities that can be detected within tattoo inks have been associated with a myriad of dermatologic complications. Legislation regarding these antigenic substances varies widely around the world, with Europe serving as both the research and regulatory center on these intradermal formulations. Although industry is said to be moving away from metallic and metalloid pigments in exchange for organic or organometallic dyes, surveys of commercially available inks continue to detect these elements at concentrations considered unsafe for application into the dermis. In order to better assess the formulation and safety of tattoo ink, we present a systematic review and meta-analysis of studies quantifying restricted metals and metalloids in commercially available tattoo ink products. Among the papers selected, inconsistencies were noted in the degree of specificity by which ink products were identified and the elements sampled for. In addition, the analytical targets' valency and/or solubility were not always considered in accordance with regulation criteria. Of note, chromium, by total content and that of its regulated +6 valency, exceeded its maximum allowed concentration in nearly every sample tested. Total copper content exceeded the limit for soluble copper in half of inks sampled. In descending order, concentrations of cadmium, barium, mercury, soluble copper, arsenic, zinc, antimony, and lead violated regulations in one-sixth or fewer of samples tested. Cobalt and tin levels never violated regulation. Overall, our findings indicate that unsafe levels of restricted elements continue to be detected across studies, warranting further investigation under a regulatory lens.

The Association of Academic Cosmetic Dermatology: improving cosmetic dermatology education through collaboration, research, and advocacy.

Cosmetic and laser procedures are increasingly popular among patients and are skills in which dermatologists are regarded as well trained. Most dermatology residents intend to incorporate cosmetic procedures into their practice and prefer to learn such procedures during residency through direct patient care. However, there are notable challenges in optimizing how residents are trained in cosmetic and laser dermatology. To address these barriers and elevate the practice of cosmetic dermatology in academic medicine, the Association of Academic Cosmetic Dermatology (AACD) was founded in 2021 as the lead professional society for dermatologists who direct the education of resident trainees in cosmetic and laser dermatology. The AACD, a group of board-certified dermatologists who teach cosmetic and laser dermatology to residents, aims to improve cosmetic dermatology education through collaboration, research, and advocacy.

Dermatological Needs in an Urban Free Health Care Setting.

Introduction A large proportion of the United States' underinsured population relies on free health clinics for their health care needs. With only a few free health clinics nationwide hosting specialty clinics, a small subset of which are dermatology clinics, there is a dearth of information in the literature on which dermatological pathologies and treatment modalities are most common in this setting. The purpose of this study was to establish the most common dermatological conditions and treatments in the free health care setting as well as understand which facets of care need improvement. Methods A total of 57 patients with dermatological findings were identified at an urban student-run free health clinic in the southern United States in the past two years (2019-2021). Information reviewed for each patient included general demographics, chief complaint, medical/surgical history, treatments/procedures required for each visit, treatments/procedures available for each visit, referrals, and follow-up rate. Qualitative analysis was performed.  Results The median age of the patients that presented with dermatological findings was 40 while the most common ethnicities were white (26.2%), Hispanic/Latino (28.6%), and black (28.6%). The most common chief complaints were rashes and cysts with a majority (63.2%) of these patients presenting to this particular clinic for the first time. Seven patients (12.3%) were unable to receive treatment due to expense, procedure unavailability, or an unknown reason. The most common treatment prescribed included a topical steroid. A majority (71.9%) of the patients were unable to follow up as scheduled. A majority of patients (81.2%) that were able to follow up were adherent to their prescribed medication. Conclusion Although dermatological conditions are plentiful in the free health care setting, the literature currently contains no information regarding this topic. This may be due to low patient follow-up rates and inadequately charted outcomes on often outdated electronic health records. In order to best care for dermatology patients in this setting, it is necessary to understand the barriers to care and available treatment options.

Ultrasound Is Not Useful in Monitoring Lipedematous Alopecia: A Clinical, Trichoscopic, Histologic, and Ultrasound Analysis of 2 Cases.

Introduction: Lipedematous scalp (LS) is a rare condition characterized by thickened adipose tissue in the subcutaneous layer of the scalp resulting in a soft, spongy, or thick consistency of the scalp. When associated with hair loss, this condition is called lipedematous alopecia (LA). Various imaging modalities have been used to diagnose LS and LA along with histopathology. Case Presentation: We present 2 cases of LS: a 56-year-old female with a 1-year history of hair thinning, pain, and tenderness at the vertex scalp and a 60-year-old female with a 5-year history of lichen planopilaris presenting with a 1-year history of itching and soreness on the crown of her head. Ultrasound (US) was used for diagnosis, treatment response surveillance, routine clinical examination, and symptom assessment. Follow-up US revealed no improvement in scalp thickness in either case despite symptom improvement and visual improvement in hair growth. Discussion/Conclusion: US has been reported as a helpful tool in the diagnosis of LS; however, treatment response was better approximated by hair growth and symptom alleviation. We found that once the diagnosis with made with US, clinical monitoring is adequate as symptom improvement and hair growth may not correlate with a change in scalp thickness.

Pediatric Lichen Planopilaris Treated With Pioglitazone: A Case Study and Literature Review.

IMPORTANCE: Pediatric lichen planopilaris (LPP) is a clinical variant of lichen planus (LP) that can lead to scarring hair loss without prompt intervention. While various therapies exist, intralesional and topical corticosteroids remain the mainstay of treatment in pediatric LPP. Refractory cases may require systemic therapies, selection of which may prove challenging due to the lack of data regarding pediatric disease and effective treatment regimens. The objective of this case study is to present a new instance of pediatric LPP and identify all reported cases of pediatric LPP with an emphasis on treatment and response.
