RESUMO

Central centrifugal cicatricial alopecia (CCCA) is the most common form of primary scarring alopecia in women of African descent, negatively impacting their quality of life. Treatment is often challenging, and we usually direct therapy to suppress and prevent the inflammation. However, factors affecting clinical outcomes are still unknown. To characterize medical features, concurrent medical conditions, hair care practices, and treatments used for patients with CCCA and assess their relationship with treatment outcomes. We analyzed data from a retrospective chart review of 100 patients diagnosed with CCCA who received treatment for at least one year. Treatment outcomes were compared with patient characteristics to determine any relationships. P-values were calculated using logistic regression and univariate analysis with 95% CI P < 0.05 was considered significant. After one year of treatment, 50% of patients were stable, 36% improved, and 14% worsened. Patients without a history of thyroid disease (P = 0.0422), using metformin for diabetes control (P = 0.0255), using hooded dryers (P = 0.0062), wearing natural hairstyles (P = 0.0103), and having no other physical signs besides cicatricial alopecia (P = 0.0228), had higher odds of improvement after treatment. Patients with scaling (P = 0.0095) or pustules (P = 0.0325) had higher odds of worsening. Patients with a history of thyroid disease (P = 0.0188), not using hooded dryers (0.0438), or not wearing natural hairstyles (P = 0.0098) had higher odds of remaining stable. Clinical characteristics, concurrent medical conditions, and hair care practices may affect clinical outcomes after treatment. With this information, providers can adjust proper therapies and evaluations for patients with Central centrifugal cicatricial alopecia.

RESUMO

Highly textured hair has been found to be more susceptible to breakage than other hair types due to an increased proportion of spirals and relatively fewer elastic fibers anchoring the hair follicles to the dermis. Women of African descent frequently employ hairstyles and hair treatments for ease of management and as a form of self-expression, but a number of these practices have been implicated as risk factors for alopecia. Herein, we provide an overview of hairstyles for patients with highly textured hair so that physicians may better identify high-risk hairstyles, provide individualized recommendations for safer alternatives, and manage and stop the progression of hair loss before it becomes permanent.

RESUMO

BACKGROUND: In central centrifugal cicatricial alopecia (CCCA), a lymphocytic scarring alopecia that primarily affects black women, it has been postulated that there is a "pro-fibrotic" tendency and increased risk for systemic fibroproliferative disorders. OBJECTIVE: To determine whether women with biopsy-proven CCCA have a greater likelihood of systemic fibroproliferative disorders (FPDs) of the lungs (interstitial lung disease), arteries (atherosclerosis of the aorta), liver (non-alcoholic steatohepatitis), kidney (end stage renal disease), or uterus (uterine leiomyoma). METHODS: We conducted a retrospective matched cohort study evaluating 427 cases with biopsy-proven CCCA and 1281 age- and sex-matched controls. RESULTS: Black women with biopsy-proven CCCA, were not more likely to have interstitial lung disease (ILD), atherosclerosis of the aorta, non-alcoholic steatohepatitis (NASH), end stage renal disease (ESRD), or uterine leiomyoma. Central centrifugal cicatricial alopecia was associated with a history of never smoking and higher body mass index. CONCLUSION: In this large cohort of biopsy-proven women with CCCA, there was no association with specific fibroproliferative disorders when compared with age and sex matched controls. Future longitudinal studies may help confirm these results.

RESUMO

Early intervention in cicatricial alopecias is critical to prevent permanent damage to the hair follicles. Previous literature, however, has suggested that individuals who are black are less likely to visit dermatologists than individuals who are white.1.

RESUMO

INTRODUCTION: Smoking has been associated with increased incidence, severity of cutaneous lupus, and lupus activity. We looked at the association of both smoking and ethnicity with the individual damage items from the SLICC/ACR Damage Index. METHODS: Poisson regression was used to model the total SLICC/ACR Damage Index score against ever smoking. Cox regression was used to assess the relationship between time to individual damage items and ever smoking. Furthermore, we compared SLICC/ACR Damage Index items among African-American and Caucasian ever smokers. RESULTS: The study included 2629 patients, 52.6% Caucasian and 39.3% African-American. The prevalence of ever smokers was 35.8%. There was no significant difference in total SLICC/ACR Damage Index score between ever smokers and never smokers after adjustment for ethnicity, gender, age at diagnosis, and years of education. Ever smokers had more atherosclerotic cardiovascular damage and skin damage compared to non-smokers. Caucasian SLE patients who ever smoked were more likely to have muscle atrophy and atherosclerosis compared to Caucasian non-smokers. African-American patients who ever smoked were more likely to have skin damage compared to African-American non-smokers. African-Americans who smoked were more likely to have many more damage items (cataract, renal damage, pulmonary hypertension, cardiomyopathy, deforming or erosive arthritis, avascular necrosis, skin damage, and diabetes) compared to Caucasians who smoked. CONCLUSION: Our analysis proved the major effect of smoking on cardiovascular and cutaneous damage. Surprisingly, cardiovascular damage items had higher hazard ratios in Caucasian smokers than non-smokers while skin damage items hazard ratios were higher in African-American smokers compared to non-smokers.Key Points• This study is the largest cohort study to date evaluating the effect of smoking on the cumulative SLICC/ACR Damage Index and its individual damage items.• It is the only study that examined the effect of smoking on individual items of the SLICC/ACR Damage Index in terms of Caucasians vs. African-American ethnicity.• Our analysis proved the major effect of smoking on cardiovascular and cutaneous damage. Compared to non-smokers, Caucasian smokers had higher risk of cardiovascular damage while African-American smokers had more skin damage.• African-Americans who smoked were more likely to have many more damage items (cataract, renal damage, pulmonary hypertension, cardiomyopathy, deforming or erosive arthritis, avascular necrosis, skin damage, and diabetes) compared to Caucasians who smoked.

RESUMO

Hair loss can be distressing for patients regardless of race, gender, or age. There are unique nuances when diagnosing, treating, and understanding the hair care practices of black patients. Treatment regimens are largely anecdotal for some of the most common types of alopecia affecting those with skin of color. The key to treatment compliance is setting expectations at the beginning of the hair loss investigation journey and developing a partnership with the patient. The treatments and diagnoses discussed herein are not a comprehensive list but represent some of the more common conditions and initial approaches to treatment.

RESUMO

BACKGROUND: Central centrifugal cicatricial alopecia (CCCA) is the most common form of scarring alopecia among women of African ancestry. The disease is occasionally observed to affect women in families in a manner that suggests an autosomal dominant trait and usually manifests clinically after intense hair grooming. We sought to determine whether there exists a genetic basis of CCCA and, if so, what it is. METHODS: We used exome sequencing in a group of women with alopecia (discovery set), compared the results with those in a public repository, and applied other filtering criteria to identify candidate genes. We then performed direct sequencing to identify disease-associated DNA variations and RNA sequencing, protein modeling, immunofluorescence staining, immunoblotting, and an enzymatic assay to evaluate the consequences of potential etiologic mutations. We used a replication set that consisted of women with CCCA to confirm the data obtained with the discovery set. RESULTS: In the discovery set, which included 16 patients, we identified one splice site and three heterozygous missense mutations in PADI3 in 5 patients (31%). (The approximate prevalence of the disease is up to 5.6%.) PADI3 encodes peptidyl arginine deiminase, type III (PADI3), an enzyme that post-translationally modifies other proteins that are essential to hair-shaft formation. All three CCCA-associated missense mutations in PADI3 affect highly conserved residues and are predicted to be pathogenic; protein modeling suggests that they result in protein misfolding. These mutations were found to result in reduced PADI3 expression, abnormal intracellular localization of the protein, and decreased enzymatic activity - findings that support their pathogenicity. Immunofluorescence staining showed decreased expression of PADI3 in biopsy samples of scalp skin obtained from patients with CCCA. We then directly sequenced PADI3 in an additional 42 patients (replication set) and observed genetic variants in 9 of them. A post hoc analysis of the combined data sets showed that the prevalence of PADI3 mutation was higher among patients with CCCA than in a control cohort of women of African ancestry (P = 0.002 by the chi-square test; P = 0.006 by Fisher's exact test; and after adjustment for relatedness of persons, P = 0.03 and P = 0.04, respectively). CONCLUSIONS: Mutations in PADI3, which encodes a protein that is essential to proper hair-shaft formation, were associated with CCCA. (Funded by the Ram Family Foundation and others.).

RESUMO

Female alopecia patients in China often present with a frontal pattern hair loss. This feature is seen less frequently in western women. Women in China frequently style their hair in a ponytail. Thus, we hypothesized that the high prevalence of frontal pattern hair loss in Chinese women is due to traction alopecia. To better understand this, we studied 43 women presenting frontal alopecia at a hair clinic. Among the women presenting frontal alopecia, 79% reported styling their hair in a ponytail four or more days per week for an average period of 10 years. To our knowledge, this is the first study to elucidate the cause of frequent frontal alopecia in Chinese women. Although cultural style changes are difficult to change, we believe that awareness of the medical implications of frequent ponytail styling will reduce the rate of frontal alopecia among Chinese women.

RESUMO

BACKGROUND: Various facial and extrafacial lesions have been reported in frontal fibrosing alopecia (FFA). Facial papules have been associated with worse prognosis. OBJECTIVES: We sought to detect the prevalence of facial and extrafacial lesions and to analyze their relation to demographic and clinical variables in a large and ethnically diverse series of patients with FFA. METHODS: Charts of patients diagnosed with FFA between January 1, 2015, and December 31, 2017, at the Department of Dermatology, University of Miami, were reviewed retrospectively. RESULTS: 91 patients (87 women and 4 men) met inclusion criteria: 45% (n = 41) were of Hispanic/Latino ethnicity, and 34% (n = 30) were premenopausal. Facial papules were most commonly detected (41% among Hispanic/Latino patients). Significant associations were found between: (1) Hispanic/Latino ethnicity and any FFA-associated facial lesions, facial papules alone, or lichen planus pigmentosus alone, as well as premenopausal status; (2) any FFA-associated facial lesions or facial papules alone and premenopausal status; and (3) Hispanic/Latino ethnicity and simultaneous presence of facial and extrafacial lesions. CONCLUSIONS: There is a significant association among Hispanic/Latino ethnicity, facial papules, and premenopausal status, which may portend a susceptibility to severer disease and prompt early and aggressive treatment in this group.

RESUMO

BACKGROUND: Differentiating scarring and nonscarring alopecia poses a diagnostic dilemma for clinicians, with histopathology used to distinguish. The extent to which dermatologists are able to clinically classify alopecia has not been evaluated. METHODS: A retrospective study of pathology reports on 458 patients was used to calculate a kappa coefficient to correlate clinical presence of scarring or nonscarring alopecia to histopathologic presence of scarring or nonscarring. A multivariate analysis was performed to assess for associations with scarring. RESULTS: The kappa correlation coefficient was 0.59 (P < 0.0001), indicating moderate agreement and varied by race and sex. There were 15 times higher odds of making the clinical diagnosis of scarring alopecia (OR 14.64 95% CI [8.64-24.18]; P < 0.001), and this increased with age. CONCLUSIONS: These results suggest that clinical exam is moderately reliable in distinguishing between scarring and nonscarring alopecia. Our results highlight the need for education and diagnostic schemata for evaluation of alopecia based on gender and in skin of color.

RESUMO

BACKGROUND: The incidence of hair loss among Chinese male has increased to 21.3 per hundred. Hair restoration has been an effective technique. Detailed hair distribution has a tremendous impact on the surgery design. OBJECTIVE: To investigate the pattern of hair distribution in Chinese young adult males. METHODS: A total of 1000 males without hair disease were enrolled. We evaluated the locations of the main anatomical marks at different sites on the scalp and analyzed the hair density and follicular unit structure using the standard photographs and trichoscope. RESULTS: The hairline shapes were classified as: linear (48.7%), linear with central protrusion (27.9%), round (9.8%), round with central protrusion (13.7%). The average height of the median line was 6.78 ±â€Š0.75 cm, the ratio of the median line and the forehead height was 0.333. The average distance from the parietal whorl to the vertical bimeatal line was 7.05 ±â€Š3.32 cm, and most of the PWs were on the right (51.4%) and had a clockwise pattern (73.3%). The hair density was 171.12 ±â€Š18.32 hairs/cm in the vertex. 1-hair follicular units were (75.90% and 56.39%) in anterior hairline and temporal area. CONCLUSION: Our study clearly assisted understanding of scalp anatomy and hair distribution in Chinese young adult males.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Research in the past half a century has gradually sketched the biological mechanism leading to androgenetic alopecia (AGA). Until recently the aetiological paradigm has been too limited to enable intelligent commentary on the use of folk remedies to treat or reduce the expression of this condition. However, our understanding is now at a point where we can describe how some folk remedies work, predict how effective they will be or why they fail. RESULTS: The new paradigm of AGA is that inheritance and androgens (dihydrotestosterone) are the primary contributors and a secondary pathology, microinflammation, reinforces the process at more advanced stages of follicular miniaturisation. The main protagonist to microinflammation is believed to be microbial or Demodex over-colonisation of the infundibulum of the pilosebaceous unit, which can be ameliorated by antimicrobial/acaricidal or anti-inflammatory therapies that are used as adjuvants to androgen dependent treatments (either synthetic or natural). Furthermore, studies reveal that suboptimal androgen metabolism occurs in both AGA and insulin resistance (low SHBG or high DHT), suggesting comorbidity. Both can be ameliorated by dietary phytochemicals, such as specific classes of phenols (isoflavones, phenolic methoxy abietanes, hydroxylated anthraquinones) or polycyclic triterpenes (sterols, lupanes), by dual inhibition of key enzymes in AGA (5α-reductase) and insulin resistance (ie., DPP-4 or PTP1B) or agonism of nuclear receptors (PPARγ). Evidence strongly indicates that some plant-based folk remedies can ameliorate both primary and secondary aetiological factors in AGA and improve insulin resistance, or act merely as successful adjuvants to mainstream androgen dependent therapies. CONCLUSION: Thus, if AGA is viewed as an outcome of primary and secondary factors, then it is better that a 'multimodal' or 'umbrella' approach, to achieve cessation and/or reversal, is put into practice, using complementation of chemical species (isoflavones, anthraquinones, procyanidins, triterpenes, saponins and hydrogen sulphide prodrugs), thereby targeting multiple 'factors'.

RESUMO

Our objective is to reported a Chinese CARASIL patient caused by novel compound heterozygous mutations in HTRA1. Detailed clinical and neuroimaging examination were conducted in proband and her available family members. Sanger sequencing of NOTCH3 and HTRA1 was used to investigate causative mutations. The patient was born in an outbred family. She experienced recurrent transient ischemic attacks, hair loss, and low back pain. Brain magnetic resonance imaging showed multiple lacunar infarctions, diffuse leukoencephalopathy, and multiple microbleeds of white matter. A compound heterozygous mutation, c.958G > A (p.D320N) and c.1021G > A (p.G341J), were identified in the proband. This report highlights that screening of HTRA1 should be considered in young SVD patient despite from outbred families.
