Among various modalities of treatment, platelet-rich fibrin (PRF) has shown promising results in ulcer healing by providing necessary growth factors. Unna's paste dressing has also proven to enhance wound healing. Aim The aim of this study is to compare the efficacy of autologous PRF versus Unna's paste dressing in chronic venous leg ulcer patients and to compare the mean reduction in ulcer area at the end of 4 weeks. Materials and Methods Twenty patients with chronic venous leg ulcers were randomly divided into two groups. Group 1 Patients received PRF dressing which was repeated every week for 4 weeks. Group 2 Patients received Unna's paste dressing once a week for 4 weeks. The ulcer size was assessed with the help of photographs, and ulcer area was measured. Results The mean reduction in the area of the ulcer size in the PRF group was 86.03% and in the Unna's paste group was 71.97%, which was not statistically significant with a P value of 0.223. Conclusion We conclude that though there was no statistical significance between the groups, PRF showed a significant reduction in ulcer size.

However, its effectiveness and safety in Indian setup have not been reported yet. Materials and Methods This was retrospective, single-center, longitudinal, observational cohort study where the total study period was 24 weeks. Effectiveness parameters were the proportion of patients achieving psoriasis area and severity index (PASI) 50, 75, 90, and 100 response at week 16 and 24. Safety was measured as the proportion of patients reporting ≥1 adverse event (AE) during the study period. Results Data of a total of 70 patients were included in our study. At week 16, 76.92%, 41.53%, 15.38%, and 6.15% patients achieved PASI 50, 75, 90, and 100, respectively. At week 24, 81.53%, 58.46%, 29.23%, and 10.76% patients achieved PASI 50, 75, 90, and 100, respectively. Mean percentage reduction in PASI was 67% at week 24 and DLQI score was reduced significantly to 3.4 from mean baseline DLQI score of 10.8 (P less then 0.001). 40% of patients reported ≥1 AE during the study period. 5 out of 70 patients discontinued apremilast due to AE. Nausea was most common AE reported by 21.4% patients followed by diarrhea (18.57%), headache (17.4%), vomiting (8%), weight loss (7.69%), myalgia (6.15%), and gastritis (6.15%). Most of the AEs were of mild-to-moderate severity. Conclusion The results of this study support the long-term use of apremilast monotherapy as an efficacious and safe treatment option for the management of moderate-to-severe plaque psoriasis.

In the past several years, it has emerged as a general public health problem in our country. Studies from different regions reveal varying patterns of etiological distribution of the disease. Aims and Objectives To estimate the prevalence of different fungal species associated with dermatophytosis and to find out any possible association of the type of fungus with different clinical parameters of the disease. Materials and Methods This was a cross-sectional study among 311 clinically diagnosed dermatophytosis cases from a tertiary care center in eastern India. Potassium hydroxide (KOH) mount and fungal culture were done from samples of skin, hair, and nails, and various clinical parameters were analyzed. Results There was a male preponderance among cases and maximum patients belonged to third decade of life. Most common presentation was tinea corporis et cruris (39.5%). Family history was positive in 48.8% of cases. Trichophyton mentagrophytes was the most common fungal species (79.91%) grown in culture followed by Trichophyton rubrum (13.53%). Majority of patients had a mild body surface area involvement. We did not find statistically significant association of any clinical parameters with type of organism isolated. Conclusion Trichophyton mentagrophytes was the most common isolated fungal species. This is in contrast to several studies where T.rubrum was the frequently found organism. There was no significant association of any clinical parameters like body surface area, number of sites, or duration of diseasewith fungal species isolated in culture.

Although a few risk factors have been identified, the exact pathogenesis remains elusive.  https://www.selleckchem.com/products/FK-506-(Tacrolimus).html  Many treatment modalities have been tried, but none have been completely successful. Aim To compare safety and efficacy of microneedling with Tranexamic acid versus microneedling with Vitamin C in the treatment of melasma. Materials and Methods It was a split face, comparative study conducted on 30 female melasma patients. After obtaining informed consent, microneedling with Tranexamic acid was done on left side and microneedling with Vitamin C was done on right side of face. The improvement was evaluated on the basis of clinical photographs, MASI, Physician Global Assessment (PGA) and Patient Global Assessment (PtGA) at each visit (0, 4 and 8 weeks). Z test was used to test the significant difference in the means of the 2 groups at 4 weeks and at 8 weeks. Results At the end of 8 weeks, MASI, PGA and PtGA showed improvement with both tranexamic acid and vitamin C. However the improvement was more with tranexamic acid than with vitamin C, although not statistically significant. Conclusion Both TXA and Vitamin C are effective and safe treatments for melasma. But, TXA was found to be more effective. Copyright © 2019 Indian Dermatology Online Journal.Background Aims and Objectives Nail changes have been reported in approximately 40% of psoriasis patients. Occasionally nail psoriasis may be the sole finding or the first presentation of the disease. Assessment of the nail changes associated with psoriasis can be done clinically, ultrasonographically, and most recently using a dermoscope. The aim of this study is to assess the dermoscopic features in nails of psoriasis as well as to compare the dermoscopic with the clinical findings. This study has also assessed the correlation between disease duration and the severity of skin and nail involvement. Materials and Methods A total of 50 patients with psoriatic nail changes were recruited in the study. The psoriasis area severity index (PASI) was used to assess the severity of the disease. The nail psoriasis severity index (NAPSI) was used to determine the severity of nail involvement. The patient's nails were examined both clinically and dermoscopically. Results Pitting was the commonest feature (84%) noted both clinically and dermoscopically.
