Background: Finasteride is a widely used drug in dermatology for the treatment of androgenetic alopecia. There are many reports of associated sexual side effects. This article reviews the use of once-daily 1 mg finasteride in androgenetic alopecia and its associated sexual adverse effects. Methods: A literature search was performed to collect data on the use of finasteride in male pattern baldness. Relevant literature published till March 2014 was obtained from MEDLINE, EMBASE, CINAHL, Cochrane registers and LILACS. The keywords "finasteride", "male pattern baldness" and "androgenetic alopecia" were used for literature search. Similarly, a search was done for finasteride in female pattern hair loss with keywords "female pattern baldness", "finasteride" and "female pattern alopecia". All systematic reviews, meta-analyses, national guidelines, randomized controlled trials, prospective open label studies and retrospective case series in the English literature were reviewed. Results: Two hundred sixty two studies were evaluated, twelve of which fulfilled the inclusion criteria. Conclusions and Recommendations: Current evidence on the safety of finasteride indicates that it is safe but there is growing concern about its sexual side effects. In view of this, proper information should be provided to patients prior to starting treatment (Level of recommendation 1+, Grade of recommendation B). The reported sexual side effects are few and reverse with stoppage of the drug (Grade of recommendation B) but further studies are required.

Background: Autologous platelet-rich plasma has recently attracted significant attention throughout the medical field for its wound-healing ability. Aims: This study was conducted to investigate the potential of platelet-rich plasma combined with fractional laser therapy in the treatment of acne scarring. Methods: Sixteen patients (12 women and 4 men) who underwent split-face therapy were analyzed in this study. They received ablative fractional carbon dioxide laser combined with intradermal platelet-rich plasma treatment on one half of their face and ablative fractional carbon dioxide laser with intradermal normal saline on the other half. The injections were administered immediately after laser therapy. The treatment sessions were repeated after an interval of one month. The clinical response was assessed based on patient satisfaction and the objective evaluation of serial photographs by two blinded dermatologists at baseline, 1 month after the first treatment session and 4 months after the second. The adverse effects including erythema and edema were scored by participants on days 0, 2, 4, 6, 8, 15 and 30 after each session. Results: Overall clinical improvement of acne scars was higher on the platelet-rich plasma-fractional carbon dioxide laser treated side but the difference was not statistically significant either 1 month after the first treatment session (P = 0.15) or 4 months after the second (P = 0.23). In addition, adverse effects (erythema and edema) on the platelet-rich plasma-fractional carbon dioxide laser-treated side were more severe and of longer duration. Limitations: Small sample size, absence of all skin phototypes within the study group and lack of objective methods for the evaluation of response to treatment and adverse effects were the limitations. Conclusion: This study demonstrated that adding platelet-rich plasma to fractional carbon dioxide laser treatment did not produce any statistically significant synergistic effects and also resulted in more severe side effects and longer downtime.

Topical calcipotriol/betamethasone dipropionate ointment/gel has been commonly used for the treatment of psoriasis vulgaris. However, the efficacy of this combination needs to be consolidated. We aimed to assess the effects and safety profile of calcipotriol/betamethasone dipropionate for the treatment of psoriasis vulgaris, using evidence based approach. Randomized controlled trials on the treatment of psoriasis vulgaris with calcipotriol/betamethasone dipropionate were identified by searching PubMed, China National Knowledge Infrastructure and the Cochrane Library. The primary outcome measure was the Psoriasis Area and Severity Index (PASI) score. Ten randomized controlled trials involving 6590 participants were included. The methodologies of the studies were generally of moderate to high quality. These trials used topical calcipotriol/betamethasone dipropionate for 4 or 8 weeks, and were compared with topical calcipotriol or betamethasone. The results showed that calcipotriol/betamethasone dipropionate was more effective than controls. A four-week treatment with calcipotriol/betamethasone dipropionate did not show any significant difference between the once-daily or twice-daily regimen. The adverse events of calcipotriol/betamethasone dipropionate were tolerable and acceptable. The reports included in this review are heterogenous and have limitations. Topical application of calcipotriol/betamethasone dipropionate once daily is an efficacious treatment for psoriasis vulgaris and is associated with few side effects.

Background: Premature canities is a common yet incompletely understood dermatological entity with scarce demographic and clinical data. Aim: Evaluation of the demographic and clinical profile of cases with premature canities and to look for systemic associations. Methods: Fifty two self-reported cases of premature canities (onset before 20 years of age) and an equal number of healthy controls were recruited from the outpatient department of the Department of Dermatology, Guru Teg Bahadur Hospital Delhi, India from November 2011 to March 2013. A detailed history including onset, duration and pattern of involvement, a family history with pedigree charting and scalp examination were recorded on a predesigned proforma. A history of atopy was looked for in all study subjects and they were screened for thyroid disorder and diabetes. Results: The mean age of cases and controls was comparable. The mean age of onset of graying was 11.6 ± 3.6 years. The mean duration at the time of presentation was 39.8 ± 37.2 months. The frontal region was the earliest affected area in 25 (48.1%) cases. Positive family history of premature canities was reported in 39 (75%) cases with an equal prevalence on paternal and maternal sides. More than half of the cases, 29 (55.8%) reported having a first degree relative affected by premature canities, 13 (25%) had a second degree and 20 (38.5%) had a third degree relative affected. Atopy was found to be strongly associated with premature canities with an odds ratio of 3.8. No association with thyroid abnormality or diabetes mellitus was seen. Limitation: The study suffered from the limitation of a small sample size. Conclusion: It was observed that the process of graying mostly starts in the frontal region. It was also found to be associated with a strong family history and atopic predisposition. Larger studies are recommended to arrive at a definite conclusion.

Background: Estimation of facial aging has assumed growing importance due to the advent of several antiaging therapies. Evidence-based estimation of global facial aging is often necessary, especially for validation of these treatment modalities. Most available methods are expensive and have been used in fair skinned individuals. Aim: We attempted to develop a clinical rating scale for the estimation of global facial aging applied on an Indian population which has brown to black skin. We have also measured the association of this rating scale score with the chronological age. Methods: Initially, a 14- item summated rating scale was developed with inputs from five dermatologists and a clinical pharmacologist. The rating scale was applied to 105 consenting subjects with healthy facial skin between 30 to 90 years of age. Intra- and inter-rater reliability was assessed. Results: The summated rating score showed a significant positive correlation with the chronological age (Pearson's correlation coefficient 0.834, P < 0.001). We omitted one item from the scale due to a low inter-rater agreement. The resulting 13-item rating scale was internally consistent (Cronbach's alpha: 0.905), with substantial inter- and intra-rater reliability (intraclass correlation coefficient: 0.973 and 0.788, respectively). Principal components and predictive equation for perceptible age were identified on further computation. Limitations: Participants of this study were limited to a particular ethnic group from West Bengal and other neighboring states of Eastern India. Conclusions: We have developed and validated a 13-item rating scale for the quantification of global facial aging suitable for Indian (brown to black) skin type. This scale can be utilized effectively for clinical estimation of global facial aging.

Background: Cutaneous leishmaniasis in India is mainly confined to the deserts of Rajasthan; some cases have been reported from the dry north-western half of the Indo-Gangetic plain, including Punjab, Himachal Pradesh, Delhi and Varanasi. Aims: To highlight a new focus of cutaneous leishmaniasis in the Jammu division of Jammu and Kashmir State, previously a non-endemic area. This report presents the clinico-epidemiological and investigative results of 120 new cases of cutaneous leishmaniasis detected between November 2012 and October 2013. Methods: The clinical diagnosis of cutaneous leishmaniasis was made using criteria proposed by Bari and Rahman. It was further confirmed by the demonstration of Leishman-Donovan bodies in Leishman stained slit skin smears and skin biopsy specimens, and/or by a satisfactory response to intra-lesional sodium stibogluconate given weekly for 4 weeks. Serial clinical photographs were taken before giving injections and at the end of the 6 ^th week. Results: There were 67 females and 53 males with an age range of 8 months to 80 years. The most frequently affected site was the face. Lesions were most commonly of the nodulo-ulcerative type. The number of lesions ranged from 1 to 4. Farmers (28.1%), homemakers (27.2%) and students (27.2%) were significantly over-represented among the occupations (P < 0.001). Skin smears and biopsies were positive for Leishman-Donovan bodies in 50.8% and 44.2% cases, respectively. Conclusions: There is a new focus of cutaneous leishmaniasis in Jammu division which deserves urgent attention from the public health angle. Further epidemiological studies are warranted to establish the identity of the vector and the strain of Leishmania involved.
