RESUMEN

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.

RESUMEN

Racial and ethnic minority patients experience worse hypertrophic scars after burn injury than White patients. Subsequently, minority patients encounter differences in scar-related recovery domains such as itch and fatigue. This study examines disparities regarding postburn injury itch and fatigue in minority patients to better inform counseling and treatment considerations. From the multicenter National Institute of Disability, Independent Living and Rehabilitation Research Burn Model System Database (2015-2019), outcomes were analyzed at three time-points (discharge from index hospitalization, 6- and 12-months post-injury) using the 5D Itch and PROMIS-29 Fatigue measures. Multilevel linear mixed effects regression modeling analyzed associations between race/ethnicities and outcomes over time. Of 893 total patients, minority patients reported higher/worse itch scores at all time points compared to White patients. Itch scores were significantly higher for Black patients at 6 months (ß = 1.42, P = .03) and 12 months (ß = 3.36, P < .001) when compared to White patients. Black patients reported higher fatigue scores than White patients at all time points. Fatigue scores were significantly higher for Hispanic/Latino patients at discharge (ß = 6.17, P < .001), 6 months (ß = 4.49, P < .001), and 12 months (ß = 6.27, P < .001) than White patients. This study supports investigation of potential factors leading to increased itch and fatigue such as sociocultural factors, disparities in healthcare access, and psychosocial impacts of these symptoms. In the short-term, minority patients may benefit from additional counseling and focused treatments addressing itch and fatigue after burn injury.

RESUMEN

OBJECTIVES: There have been few studies regarding the use of a picosecond-domain laser for acne scars in Asians. This prospective study evaluated the efficacy and safety of a high-energy 1,064 nm Nd:YAG picosecond-domain laser for ablation and resurfacing of facial acne scars in Asians. METHODS: Subjects were treated with a 1,064 nm picosecond laser (8 mm spot, 0.7-1.0 J/cm2 , 5 Hz) every 4 weeks for three sessions. Two blinded dermatologists evaluated the pre- and 3-month post-treatment images with a 10-point improvement scale. Subject pain, global improvement, and satisfaction were also assessed. The Facial Acne Scar Quality of Life (FASQoL) questionnaire was used to evaluate the subjects' quality of life. RESULTS: Twenty subjects aged 18-50 years with Fitzpatrick skin type III-V were enrolled. The median dermatologist-rated improvement score was 3 out of 10. Subjects were satisfied to very satisfied with global improvement. Subjects' quality of life significantly improved with a median FASQoL score of 10 after treatment compared with 21 before treatment (P < 0.001). Adverse effects were limited to erythema, pain, and edema without postinflammatory hyperpigmentation. CONCLUSIONS: The 1,064 nm picosecond-domain laser with ablative resurfacing parameters is safe and effective for the treatment of acne scars in Asians. Lasers Surg.

RESUMEN

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.

RESUMEN

IMPORTANCE: Scar outcomes following cleft lip repair are an important component of pediatric patient and family satisfaction and indicate the need for future surgical interventions. OBJECTIVE: To assess the association of pediatric patient demographic factors and scar anatomic features with scar outcomes following cleft lip surgical repair. DESIGN, SETTING, AND PARTICIPANTS: A case-control study was conducted involving 58 pediatric patients who underwent surgical repair of a cleft lip from October 31, 2008, to August 4, 2016, at a tertiary care pediatric specialty hospital. Data on patient demographic factors, cleft type, and the surgical technique used were collected and analyzed from June 11, 2009, to November 21, 2017. Scar outcomes were subjectively rated by 3 physicians at 6-month and 12-month postoperative intervals. MAIN OUTCOMES AND MEASURES: Overall scar outcomes at 6-month and 12-month postoperative intervals were based on rating of scar appearance, color, width, height, and alignment by using a subjective, 5-point scar-assessment scale in which 1 indicated the poorest aesthetic appearance and 5, the ideal aesthetic appearance. RESULTS: A total of 58 pediatric patients who underwent cleft lip repair were evaluated; mean (SD) age at time of repair, 4.8 (3.0) months. Of these, 44 (76%) were male and 14 (24%) were female, 37 (64%) were white, 11 (19%) were black, 7 (12%) were Hispanic, 2 (3%) were Asian, and 1 (2%) was of another race/ethnicity. Scores on the Cohen κ interrater test indicated either a substantial or almost perfect strength of agreement among the physicians grading the scar outcomes. At 12 months, patients with black skin type had worse overall scar outcomes than patients with white skin type (odds ratio [OR], -0.31; 95% CI, -1.15 to -0.14; P = .03). A depressed scar height (OR, -0.54; 95% CI, -1.32 to -0.49; P < .001), and hypopigmented scar color (OR, -0.45; 95% CI, -1.34 to -0.32; P = .002) were associated with worse scar outcomes at 12 months following surgery. The overall median lip scar outcome significantly improved between the 6-month and 12-month follow-up assessments (scar-assessment scale score, 3.3; interquartile range [IQR], 2.7-4.0 vs 4.0; IQR, 3.3-4.3; P < .001). No association was observed between the anatomic type and severity of the cleft lip and scar outcomes (unilateral vs bilateral cleft, complete vs incomplete or microform cleft, and lip height ratio of the unilateral noncleft to cleft lip). CONCLUSIONS AND RELEVANCE: This study's findings suggest that, compared with white pediatric patients, black pediatric patients exhibited worse overall scar outcomes. A depressed scar and a hypopigmented scar also were associated with overall worse scar appearance after surgical repair. Cleft lip scar outcomes were not significantly associated with the type and severity of the cleft lip.

RESUMEN

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.

RESUMEN

On physical examination, refugees from countries in Africa, Asia, and the Middle East often present with findings that are unfamiliar to primary health care providers in the West. Previous traditional practices that may have left their mark include scarification and burning of the skin, excision of body parts, and subcutaneous insertion of foreign material. The descriptions detailed here introduce providers to some of the signs that result from body modification practices commonly encountered on physical examination of refugees.

RESUMEN

BACKGROUND: Facial hypopigmented scars are usually characterized by white color and a glossy surface. To correct the two problems simultaneously, the authors attempted to induce persistent postinflammatory hyperpigmentation for color and to build multiple pitted scars like facial skin pores for texture. This study describes a laser hole method using a traditional nonfractional carbon dioxide laser for treatment of facial hypopigmented scars and evaluates the clinical results. METHODS: Forty-three facial hypopigmented scars in 27 patients were treated, excluding protruding or thick scars. A carbon dioxide laser was set in the superpulse mode by continuous delivery. Multiple small holes were made in the scar at a distance of 1 to 3 mm. Each laser hole was produced by continuously repeated shots at one point until the deep dermis was involved. All lesions were exposed without protection. At 1 or 2 months after initial treatment, the remaining hypopigmentation was treated by the same procedure. RESULTS: Treatment sessions were performed once for nine scars, twice for 22 scars, and three times for 12 scars. In most cases, postinflammatory hyperpigmentation was slightly diminished but maintained until the last follow-up. The fine irregular surface with multiple pitted scars was similar to that of normal skin. Scar improvement evaluation showed marked or excellent in 39 scars (90.7 percent) and minimal or partial in four deep or thick scars. CONCLUSION: The laser hole technique using a nonfractional carbon dioxide laser may be an excellent option for simultaneously treating the color and texture of superficial or thin hypopigmented facial scars in Asians.

RESUMEN

BACKGROUND: Acne scarring is a common disfiguring sequela of acne vulgaris which can lead to serious psychosocial problems and have a negative effect on patients' quality of life. Although a variety of approaches can be used to treat atrophic acne scars, disadvantages such as long-healing time, dyspigmentation, infections, and prolonged erythema make these treatments unsatisfactory especially for Asians. Fractional micro-plasma radio-frequency is a novel technology that produces minor ablation to the epidermis to promote rapid re-epithelialization, while the radio-frequency evoked thermal effect can stimulate regeneration and remodeling of dermal fibroblasts. OBJECTIVE: To evaluate the clinical effectiveness and safety of micro-plasma radio-frequency for the treatment of facial acne scars in Chinese patients. MATERIALS AND METHODS: A total of 95 patients with facial atrophic acne scars were treated by micro-plasma radio-frequency using three sessions at 2-month intervals. Patients were seen 1 week after each treatment and 1, 3, 6 months after the final treatment. Improvement was assessed by three independent dermatologists who compared photographs taken before the first treatment and 6 months after the last treatment. Adverse effects were evaluated by a dermatologist who did not participated in the study. Patients also provided self-evaluation of satisfaction levels at the last follow-up visit. RESULTS: A total of 86 patients with atrophic acne scars completed the entire study. There was a significant improvement in acne scars after three treatments. The mean score of ECCA grading scale (Echelle d'Evaluation Clinique des Cicatrices d'Acné) was reduced from 107.21 to 42.27 (P < 0.05). A total of 15 of 86 patients showed more than 75% improvement, 57 patients showed 50-75% improvement, and 14 patients showed 25-50%. After three treatments, all subjects showed improvements in spots, large pores, texture, UV damage, red areas, and porphyrin fluorescence. Pain, erythema, edema, effusion, and scab formation were observed in all patients. The average pain score on a visual analog scale was 6.14 ± 1.12 and all patients tolerated the treatments. The average duration of erythema was 6.26 ± 0.92 days. Hyperpigmentation, hypopigmentation, infections, and worsening of scarring were not seen. All patients were either "very satisfied" or "satisfied" with the treatment outcomes. CONCLUSIONS: Fractional micro-plasma radio-frequency is an effective and safe treatment for acne scars, and might be a good choice for patients with darker skin. Lasers Surg.

RESUMEN

BACKGROUND: Fractional carbon dioxide (CO2) laser resurfacing unites the idea of fractional photothermolysis with an ablative 10,600-nm wavelength. This technology permits effective treatment of acne scarring, with shorter recovery and a decreased side effect profile as compared to traditional CO2 laser resurfacing. OBJECTIVE: The aims of this study were to study the efficacy and safety of fractional CO2 laser for acne scars in Asian patients. METHODS: This was a retrospective study of all patients treated with the fractional CO2 laser for facial acne scarring between January 2, 2008, and December 31, 2010, at the National Skin Centre, Singapore. Data reviewed included sex, age, and severity of acne, type of scarring, previous treatment history, frequency of treatments, adverse events, and efficacy. RESULTS: Two hundred and ten fractional CO2 laser treatments for facial acne scars were performed on 107 patients (65 men and 42 women, Fitzpatrick skin Types II to V) during the study period. Sixteen of 107 patients experienced (15.0%) adverse events. The adverse events include hyperpigmentation (6.4%), blistering (4.0%), crusting (2.9%), aggravation of inflammatory acne lesions (1.7%), and scarring (0.6%). There were no reported side effects of hypopigmentation, bacterial or viral infection. Follow-up results after final laser treatment showed that 66.4% of patients reported Grade 1 skin texture improvement, that is, <25% (n = 71); 30.0% had Grade 2 improvement, that is, 25% to 50% improvement (n = 31); 3.7% had Grade 3 improvement, that is, 51% to 75% improvement (n = 4); and 0.9% had Grade 4 improvement, that is, >75% improvement (n = 1). CONCLUSION: The study demonstrated the efficacy and safety of a fractional CO2 laser in the treatment of acne scars in Asian. Future studies are required to establish optimum treatment parameters and achieve better clinical results.

RESUMEN

BACKGROUND: Laser and other energy devices are emerging, minimally invasive treatments for scars. Among the various techniques, fractional microplasma radiofrequency technology (FMRT) has proven to be an effective treatment option for various types of scars and skin conditions such as rhytids, striae distensae, and hyperpigmentation. OBJECTIVE: This prospective clinical trial was designed to evaluate the efficacy and safety of FMRT for treating non-hypertrophic post-burn scars in the Asian population. METHOD: All patients underwent three to five treatment sessions at various intervals of 8-16 weeks. The Patient and Observer Scar Assessment Scales (POSAS) [20] were used to evaluate changes in burn scars pre-and post-FMRT treatment. RESULTS: A total of 95 patients completed the study. The overall response rate was 86.3% (82/95). The total POSAS scores before and after 6 months of treatment were 53.41 ± 6.28 and 46.35 ± 5.30, respectively. There was statistically significant improvement in scar color, thickness, and pliability. There was no improvement in vascularization, pain, or itching. Complications included prolonged post-inflammatory hyperpigmentation, acne eruption, herpes simplex eruption, and abnormal hair growth. No severe adverse events, such as acute skin infection, hypertrophic scarring, or depigmentation, were observed. CONCLUSION: FMRT is an efficacious, safe treatment for non-hypertrophic burn scars in the Asian population. Lasers Surg. Med. 49:563-569, 2017. © 2017 Wiley Periodicals, Inc.

RESUMEN

BACKGROUND: Microneedle fractional radiofrequency has been reported to be effective for improving wrinkles, enlarged pores and various scars. Sublative fractional radiofrequency has been shown to induce both fractional ablation of epidermis and upper dermal remodelling, which had rejuvenation effects in photoaged skin. Both modalities may have the potential synergy to improve acne scars. OBJECTIVE: To evaluate the efficacy and safety of combined microneedle and sublative fractional radiofrequency for acne scars in Asian skin. METHODS: Twenty subjects comprised 11 males and 9 females (mean age 23.65 ± 2.94, skin phototype III-IV) with moderate to severe acne scars. The subjects received three consecutive combined microneedle and sublative fractional radiofrequency at 4-week intervals over 12 weeks. Both blinded dermatologists and subjects assessed the clinical improvement based on the standardized photography and questionnaires, respectively. The quartile grading scale was utilized and defined as follows: grade 1, 0-25% improvement; grade 2, 26-50% improvement; grade 3, 51-75% improvement and grade 4, 76-100% improvement. RESULTS: All 20 subjects were assessed to have grade 2 or more clinical improvement by physicians; four (20%) had grade 4, 10 (50%) had grade 3, and six (30%) had grade 2 improvement. The subjects' grading also showed a good concordance as indicated by Kappa index of 0.695. The mean duration of post-therapy crusting was 5.2 days and post-therapy erythema lasted 2.5 days. CONCLUSION: Combined microneedle and sublative fractional radiofrequency can have a positive therapeutic effect with no serious complications and may provide a new therapeutic approach on acne scars in Asians.

RESUMEN

IMPORTANCE: Myocardial scarring leads to cardiac dysfunction and poor prognosis. The prevalence of and factors associated with unrecognized myocardial infarction and scar have not been previously defined using contemporary methods in a multiethnic US population. OBJECTIVE: To determine prevalence of and factors associated with myocardial scar in middle- and older-aged individuals in the United States. DESIGN, SETTING, AND PARTICIPANTS: The Multi-Ethnic Study of Atherosclerosis (MESA) study is a population-based cohort in the United States. Participants were aged 45 through 84 years and free of clinical cardiovascular disease (CVD) at baseline in 2000-2002. In the 10th year examination (2010-2012), 1840 participants underwent cardiac magnetic resonance (CMR) imaging with gadolinium to detect myocardial scar. Cardiovascular disease risk factors and coronary artery calcium (CAC) scores were measured at baseline and year 10. Logistic regression models were used to estimate adjusted odds ratios (ORs) for myocardial scar. EXPOSURES: Cardiovascular risk factors, CAC scores, left ventricle size and function, and carotid intima-media thickness. MAIN OUTCOMES AND MEASURES: Myocardial scar detected by CMR imaging. RESULTS: Of 1840 participants (mean [SD] age, 68 [9] years, 52% men), 146 (7.9%) had myocardial scars, of which 114 (78%) were undetected by electrocardiogram or by clinical adjudication. In adjusted models, age, male sex, body mass index, hypertension, and current smoking at baseline were associated with myocardial scar at year 10. The OR per 8.9-year increment was 1.61 (95% CI, 1.36-1.91; P < .001); for men vs women: OR, 5.76 (95% CI, 3.61-9.17; P < .001); per 4.8-SD body mass index: OR, 1.32 (95% CI, 1.09-1.61, P = .005); for hypertension: OR, 1.61 (95% CI, 1.12-2.30; P = .009); and for current vs never smokers: 2.00 (95% CI, 1.22-3.28; P = .006). Age-, sex-, and ethnicity-adjusted CAC scores at baseline were also associated with myocardial scar at year 10. Compared with a CAC score of 0, the OR for scores from 1 through 99 was 2.4 (95% CI, 1.5-3.9); from 100 through 399, 3.0 (95% CI, 1.7-5.1), and 400 or higher, 3.3 (95% CI, 1.7-6.1) (P ≤ .001). The CAC score significantly added to the association of myocardial scar with age, sex, race/ethnicity, and traditional CVD risk factors (C statistic, 0.81 with CAC vs 0.79 without CAC, P = .01). CONCLUSIONS AND RELEVANCE: The prevalence of myocardial scars in a US community-based multiethnic cohort was 7.9%, of which 78% were unrecognized by electrocardiography or clinical evaluation. Further studies are needed to understand the clinical consequences of these undetected scars.

RESUMEN

Postinflammatory hyperpigmentation (PIH) is the most common adverse effect of laser treatment in dark-skinned individuals. Little is known whether PIH can be prevented or minimised. The objective of this study was to investigate the effect of short-term application of topical corticosteroids on the incidence of PIH after ablative fractional resurfacing in Asians. Forty subjects with skin phototype IV and atrophic acne scars were treated with a fractional CO2 laser on both sides of the face. Post-operatively, clobetasol propionate 0.05% ointment was applied to one randomly selected side of the face for the first 2 days, followed by an application of petrolatum jelly for the rest of the week (petrolatum was applied to the other side for 7 days). Assessments on the clinical outcome, the wound healing process and the occurrence of PIH were obtained once weekly for the first month and at 2 and 3 months post-treatment. The side of the face treated with petrolatum alone had significantly (p < 0.001) higher incidence of PIH (75%) after laser irradiation than the side of the face treated with topical corticosteroids and petrolatum (40%). The PIH occurring on the petrolatum-treated sides had significantly higher intensity (p < 0.001) and was spread over a significantly larger area (p < 0.001), compared with the corticosteroid- and petrolatum-treated sides. In conclusion, a short-term application of topical corticosteroids postoperatively is associated with a decreased risk of PIH after ablative fractional resurfacing.

RESUMEN

The pathologic findings in Central Centrifugal Cicatricial Alopecia (CCCA) have not been studied systematically in horizontal sections. Our objective was to establish the pathologic features, and their frequency in horizontal sections of scalp biopsies obtained from patients with clinically and histologically proven CCCA. Serial horizontal sections of 51 cases were evaluated retrospectively. All biopsies were assessed at 4 levels and at least on 24 horizontal sections. The most common pathologic findings were follicular miniaturization (81% of the cases); premature desquamation of the inner root sheath (96%), focal preservation of the sebaceous glands (94%), which in most of these cases appeared as surrounding "in a hug" an intact vellus follicle; compound follicular structures with perifollicular fibrosis and/or inflammation (89%), lamellar hyperkeratosis/parakeratosis in the hair canal (79%), absent or mild inflammation (77%), and naked hair shafts (68%). Horizontal sections are useful in CCCA to identify early or focal disease and to provide the clinician with better information on the presence of follicular miniaturization, inflammation, and scarring, which can be used to tailor the treatment to the individual patient.

RESUMEN

BACKGROUND: Postacne scarring is disfiguring, both physically as well as psychologically. Over the past two decades, multiple modalities for treatment of acne scars have emerged and microneedling with dermaroller is one of them. OBJECTIVE: To evaluate the efficacy and safety of microneedling treatment for atrophic facial acne scars. MATERIAL AND METHODS: Thirty-six patients (female--26, male--10) of postacne atrophic facial scars underwent five sittings of dermaroller under topical anesthesia at monthly intervals. Objective evaluation of improvement was performed by recording the acne scar assessment score at baseline and thereafter at every visit. Pre- and posttreatment photographs were compared, and improvement was graded on quartile score. Final assessment was performed 1 month after the last sitting. Patients were asked to grade the improvement in acne scars on visual analog scale (VAS, 0-10 point scale) at the end of study. RESULTS: Of 36 patients, 30 completed the study. The age group ranged from 18 to 40 years, and all patients had skin phototype IV or V. There was a statistically significant decrease in mean acne scar assessment score from 11.73 ± 3.12 at baseline to 6.5 ± 2.71 after five sittings of dermaroller. Investigators' assessment based on photographic evaluation showed 50-75% improvement in majority of patients. The results on visual analog scale (VAS) analysis showed "good response" in 22 patients and "excellent response" in four patients, at the end of study. The procedure was well tolerated by most of the patients, and chief complications noted were postinflammatory hyperpigmentation in five patients and tram-trek scarring in two patients. CONCLUSION: Microneedling with dermaroller is a simple and cheap, means of treatment modality for acne scars remodulation with little downtime, satisfactory results and peculiar side effects in Asian skin type.

RESUMEN

Central centrifugal cicatricial alopecia is an inflammatory type of central scalp hair loss seen primarily in women of African descent. The prevalence is unknown, but may vary from 2.7% to 5.7% and increases with age. This review outlines the history and current beliefs and identifies clues for future research for this enigmatic condition. Despite that the cause of central centrifugal cicatricial alopecia is unknown, research is ongoing. The role of cytokeratins, androgens, genetics, and various possible sources of chronic inflammation in disease pathogenesis remain to be elucidated.

RESUMEN

BACKGROUND: Central centrifugal cicatricial alopecia (CCCA) is the commonest type of primary scarring alopecia in women of African descent. Little is currently known about the disease genetics. OBJECTIVE: We sought to investigate patterns of inheritance in CCCA and ascertain the contribution of nongenetic factors such as hair-grooming habits to the pathogenesis of the disease. METHODS: Affected individuals with at least 1 available family member were recruited from 2005 through 2012 inclusive for pedigree analysis. CCCA was diagnosed on clinical and histopathological grounds. RESULTS: Fourteen index African families with 31 immediate family members participated in the initial screening. The female to male ratio was 29:2 with an average age of 50.4 years. All patients displayed histologic features typical for CCCA. Pedigree analysis suggested an autosomal dominant mode of inheritance. Hair-grooming habits were found to markedly influence disease expression. LIMITATIONS: Small number of patients is a limitation. CONCLUSION: CCCA can be inherited in an autosomal dominant fashion, with partial penetrance and a strong modifying effect of hairstyling and gender.
