Abstract

Background and Aim: Cicatricial alopecia is the result of irreversible substitution of hair follicles with fibrotic tissue and presents as permanent loss of hair. Only a few studies have investigated the clinical and histopathological characteristics of cicatricial alopecia in Iran. The aim of this study was to determine the demographic, clinical and histopathological characteristics of patients with cicatricial alopecia who referred to our dermatology outpatient clinic in Farshchian hospital in a two year period, and to evaluate the diagnostic value of histopathologic criteria in diagnosing different kinds of cicatricial alopecias.

Methods: This was a cross-sectional study. Eighty nine patients who underwent skin biopsy due to clinical diagnosis of cicatricial alopecia were included. Demographic and clinical characteristics of patients as well as clinical diagnosis were recorded and the biopsy samples were evaluated by two different pathologists who were unaware of each other's diagnosis. Histopathological diagnosis of patients according to each pathologist's opinion was recorded separately and statistical analysis was performed to obtain the coincidence coefficient between two pathological diagnosis.

Results: The most common forms of cicatricial alopecias due to clinical and histopathological diagnosis were: lichen planopilaris, disciod lupus erythematosus, alopecia areata, pseudopelade of Brocq, folliculitis decalvans and central centrifugal cicatricial alopecia. Moreover, our findings showed a powerful coincidence coefficient between clinical diagnosis and the first pathologist diagnosis (kappa=0.836), an average to powerful coincidence coefficient between the second pathologist diagnosis and clinical diagnosis
(kappa=0.703) and finally an average to powerful coincidence coefficient between the two pathologists diagnosis
(kappa=0.663).

Conclusion: Diagnosis of cicatricial alopecia depends upon clinical and also histopathological examination. Diagnostic value of histopathological criteria even at the end of scarring process when there is considerable overlap between microscopic findings of different etiologies of cicatricial alopecias is still acceptable and there is no need to re-evaluate the biopsy specimen by a second pathologist in order to confirm the diagnosis.

Abstract
Background and Aim: Seborrhoic dermatitis is one of the most common diseases in dermatology with a prevalence of about 2%. Many treatments have been used for this disease. This Study aimed to investigate the efficacy of betamethasone lotion compared with clotrizone lotion in patients with seborrheic dermatitis of face and scalp.

Methods: This double blind study was performed on 60 patients with  seborrheic dermatitis older than 18 years, who refered to Emam Reza hospital, Mashhad. Patients were divided into two groups: clotrizone (31) and betamethasone group (29 patients). Patients were treated for a month. We evaluated severity of pruritus, erythema and desquamation of the face and scalp.

Results: The average age of patients participating in the study was 33.1 years (18 to 56 years) and 56.7% of patients were male. No significant differences were found in age and gender between the two groups (P> 0.05). Both treatments reduced severity of erythema and desquamation of the face and scalp (P<0.001). Two weeks after treatment, clotrizone had better performance, but there after both lotions had similar effect. Betamethasone reduced pruritus more than clotrizone.

Conclusion: This study showed that both  betamethasone and clotrizone  were effective. Clotrizone has better impact on the severity of erythema and scaling and betamethasone has better effect on improving the severity of pruritus.

Volume 11, Issue 3 (Volume 11, No 3 2020)
Abstract

Background and Aim: Trichoscopy is a non-invasive diagnostic tool for hair diseases. The aim of this study was to evaluate the trichoscopic findings in different types of alopecia. 

Methods: This cross-sectional study was conducted on 155 alopecia patients referring to Hamadan’s Sina hospital from March 2019 to July 2020. The patients were recruited after giving written informed consent. Scalp biopsy was performed to confirm the diagnosis and trichoscopic evaluation was then carried out. Trichoscopic findings along with demographic data were recorded. Data was analyzed using SPSS 16.0 software and appropriate statistical methods.

Results: A total of 155 patients including 79 males and 76 females were included in the study. The most common trichoscopic finding in alopecia areata was vellus hair (95.5%). The most common finding in androgenetic alopecia (AGA) was hair shaft thickness heterogeneity which was observed in all AGA patients. The most common findings in telogen effluvium (TE) were single hair pilosebaceous units, peripilar sign, thin terminal hairs and upright regrowing hairs which were observed in all TE patients. The most common finding in lichen planopilaris was perifollicular scaling (81.8%). The most common findings in discoid lupus erythematosus were large yellow dots (100%) and fine scaling (100%). Black dot was the most prevalent finding in tinea capitis (85.7%). 

Conclusion: Trichoscopy ,as a non-invasive tool, could be helpful in differentiating different types of alopecia.


Comparison of the efficacy of fractional CO2 laser with microneedling in management of patients with atrophic acne scars: a single-blind clinical trial
Sina Khanali, Alirezaei Pedram , Jalal Poorolajal,
Volume 11, Issue 4 (Volume 11, No4 2021)
Abstract

Background and Aim: Atrophic scars constitute a common complication of acne and various methods have been proposed for their treatment. This study aims at comparing the efficacy of fractional CO2 laser with microneedling in the management of atrophic acne scars.

Methods: Patients with atrophic acne scars presenting to dermatology clinic of Hamadan’s Sina hospital between March 2016 and March 2018 were included in the study. Every 3 weeks, each patient received fractional CO2 laser on one side of the face and microneedling on the other side, for a total of 4 sessions. Patient’s satisfaction and the severity of scars (based on Goodman and Baron’s scar scale) were assessed 1, 2 and 6 months thereafter.

Results: Overall, 24 participants were included. Prior to intervention, no significant difference was observed between groups in terms of mean scar score (P=0.726). At 1, 2 and 6month follow-up visits, the scar score of the side treated with laser was significantly lower than the microneedling side (P for 1, 2 and 6month follow-up visits: 0.033, 0.008 and 0.014). No significant difference was observed between groups in terms of patient’s satisfaction (P for 1, 2 and 6 month follow-up visits: 0.589, 0.469 and 0.840). The most prevalent side effect was erythema in 3 patients treated with laser. Due to low prevalence, statistical analysis of side effects between groups was impossible.

Conclusion: Compared to microneedling, fractional CO2 laser was more effective in reducing the scar score of patients. The prevalence of side effects in both treatments were low.

Volume 12, Issue 1 (Volume 12, No 1 2021)
Abstract

Background and Aim: Acne vulgaris is one of the most common skin disorders, affecting more than eighty percent of individuals around puberty. Because of the adverse effects on the patient’s appearance, the disease may have detrimental psychological impacts such as low self-esteem and social isolation. The aim of the present study was to evaluate factors affecting self-esteem in patients with acne vulgaris in Hamadan.

Methods: Patients with acne vulgaris referred to the  dermatology clinic of Hamadan’s Sina Hospital (as the case group), and their healthy accompanying persons (as the control group) were included in the study. After obtaining written informed consent, demographic dat

a were recorded and participants were asked to fill out a questionnaire. To assess the severity of acne, Global Acne Grading System (GAGS) was used. In addition, Coopersmith Inventory was applied to measure the self-esteem of the participants. In data were analyzed using STATA 14.0 software.

Results: Overall, 184 patients with acne and 177 controls were included in this study. The mean age of patients and controls was 17.89+3.13 and 17.72+2.94, respectively. Independent samples t-test showed that the mean Self-Esteem Index of patients was significantly lower than controls (32.04+8.29 vs. 34.85+7.73, P<0.001). The severity of acne was inversely correlated with self-esteem; one score increase in GAGS would result in 0.1 unit decrease in self-esteem index (P<0.001).

Conclusion: Acne vulgaris is associated with low self-esteem and the severity of acne is inversely correlated with self-esteem level.
