Background: The improvement in insulin resistance and acne lesions on low glycemic load diets in various studies suggests that diet plays a significant role in acne pathogenesis., Aims: To compare the efficacy of a low glycemic load diet plus topical benzoyl peroxide 2.5% gel with that of only topical benzoyl peroxide 2.5% gel in grades 1, 2 and 3 of acne vulgaris., Methods: In a randomized controlled trial, 84 patients with grades 1, 2 and 3 acne vulgaris were divided into two groups, to receive a low glycemic load diet and no dietary intervention respectively. Acne lesions (face) were scored and graded at baseline and 4, 8 and 12 weeks. Homeostasis model assessment of insulin resistance and body mass index were measured during the first and last visits. Statistical analysis was done with Statistical Package for the Social Sciences, version 17.0., Results: Both groups showed significant reduction in acne counts at 12 weeks (P = 0.931) with no statistically significant difference between the groups. The differences in body mass index and homeostasis model assessment of insulin resistance between the groups were statistically significant (P = 0.0001). Group 1 showed reductions in body mass index and homeostasis model assessment of insulin resistance values at the end of the study, whereas group 2 did not., Limitations: Application of mild topical cleanser in both the groups might have contributed to the improvement in epidermal barrier function, and topical application of 2.5% of benzoyl peroxide gel in both groups contributed to the improvement in acne counts., Conclusions: A low glycemic load diet did not result in any significant improvement in acne counts., Competing Interests: None

Background: Androgenic alopecia has been associated with an increased risk of coronary heart disease in various studies. The relationship between androgenic alopecia and metabolic syndrome, a known risk factor for atherosclerotic cardiovascular disease, is still poorly understood., Aim: To study the association between metabolic syndrome and early-onset androgenic alopecia., Methods: A hospital-based analytical cross-sectional study was done on men in the age group of 18-55 years. Eighty five clinically diagnosed cases with early-onset (<35 years) androgenic alopecia of Norwood grade III or above, and 85 controls without androgenic alopecia were included. Data collected included anthropometric measurements, arterial blood pressure and history of chronic diseases. Fasting blood and lipid profile were determined. Metabolic syndrome was diagnosed as per the new International Diabetes Federation criteria. Chi-square and Student's t-test were used for statistical analysis using Statistical Package for the Social Sciences (SPSS) version 17.00., Results: Metabolic syndrome was seen in 19 (22.4%) patients with androgenic alopecia and 8 (9.4%) controls (P = 0.021). Abdominal obesity, hypertension and lowered high-density lipoprotein were significantly higher in patients with androgenic alopecia versus their respective controls., Limitations: The limitations of our study include small sample size in subgroups and the lack of evidence of a temporal relationship between metabolic syndrome and androgenic alopecia., Conclusion: A higher prevalence of metabolic syndrome is seen in men with early-onset androgenic alopecia. Early screening for metabolic syndrome and its components is beneficial in patients with early-onset androgenic alopecia.

Ciprofloxacin is one of the most commonly used antibacterial agents with relatively few side effects. Serious adverse reactions reported with ciprofloxacin are rare with an incidence of 0.6%. Recently we came across two rare adverse effects of ciprofloxacin, viz. toxic epidermal necrolysis and agranulocytosis. To our knowledge, a total of seven cases have been reported in the literature documenting an association between oral ciprofloxacin administration and toxic epidermal necrolysis. One case of granulocytopenia, four of pancytopenia and fifteen of leucopenia worldwide have been reported. With the use of ciprofloxacin becoming more and more widespread, these two rare but fatal complications of ciprofloxacin should be borne in mind.

A 28-year-old female born to consanguineous parents, presented with progressive palmoplantar keratoderma since the age of six months and a constricting band on right fourth finger of one year duration. There was history of similar complaints being present in two other family members. Associated clinical findings included starfish-shaped cornified plaques on knuckles, resorption of distal phalanges and keratotic plaques on elbows, groins and knees. The patient was mentally sound and had normal audiometry. Biopsy from hyperkeratotic plaque showed hyperkeratosis, parakeratosis, increased granular layer and papillomatosis. Gene mapping for loricrin mutation was found to be negative.

Knowledge of local anesthesia is critically important to perform dermatological surgery. Local anesthetics when used judiciously are extremely safe and allow dermatologists to perform a variety of procedures. This article aims to provide an updated review of local anesthesia and local anesthetic drugs. Side effects of local anesthetics and techniques of regional anesthesia are discussed and some commonly used nerve blocks are explained. A detailed knowledge of the pharmacology of local anesthetics aids in optimal therapeutic use, and in prevention, early diagnosis and management of their toxicities by the clinician.
