Background: Chronic ulcers are defined as the breakdown of the epidermal and dermal tissue lasting for more than 6 weeks. There will be a lack of necessary growth factors in chronic non-healing ulcers. This study is aimed at accessing the efficacy of autologous platelet-rich fibrin in chronic non-healing ulcers., Aims and Objectives: To determine the efficacy of autologous platelet-rich fibrin in chronic non-healing ulcers and to compare the rate of healing in different ulcers based on aetiology., Methods: A hospital-based prospective study was conducted at the Department of Dermatology, Venereology, and Leprosy, at a tertiary care centre in Central Karnataka with 50 cases of chronic non-healing ulcers over 2 years. In each case baseline data including age and gender was collected and thorough general physical, local, and systemic examinations were done with the help of a predesigned proforma. PRF dressing was done weekly for 4 weeks with ulcer volume measured each time and improvement accessed., Results: In this study, the mean age of the study population was 43.56 ± 14.06 years, with 84% males. Good improvement in the volume of the ulcer was seen in 6 patients out of 50, moderate improvement was seen in 20 out of 50 patients and mild in the rest of the 24 patients. Improvement was more in the educated sector, more so in females and patients with trauma as the cause of ulcers without any comorbidities. Leprosy followed by diabetes was the main cause of chronic non-healing ulcers., Conclusions: This study shows that autologous platelet-rich fibrin therapy provides faster wound healing in chronic non-healing ulcers with no adverse events., Competing Interests: There are no conflicts of interest., (Copyright: © 2023 Indian Journal of Dermatology.)

Naegeli-Franceschetti-Jadassohn syndrome is a rare autosomal dominant form of ectodermal dysplasia affecting sweat glands, nails, teeth, and skin. We report a case of 16-year-old female who had generalized reticulate pigmentation, dental changes, nail changes, and absence of dermatoglyphics and hypohydrosis., Competing Interests: There are no conflicts of interest.

Rickettsial diseases are some of the most covert reemerging infections of the present times. They are generally incapacitating and notoriously difficult to diagnose; untreated cases can have fatality rates as high as 30%-35%, but when diagnosed properly, they are often easily treated but lack of definite diagnostic tools and the hazards of handling these microorganisms aggravate the difficulties of diagnosis and treatment., Competing Interests: There are no conflicts of interest. What is new? In cases of purpura fulminans, Rickettsial infections should be considered as an etiologyIn India, Scrub typhus and Indian Tick Typhus are most common type of Rickettsial infections.

Background: Phrynoderma is a type of follicular hyperkeratosis. Various nutritional deficiency disorders have been implicated in the etiology of phrynoderma., Aim: To determine clinical features of phrynoderma and its association with nutritional deficiency signs., Materials and Methods: A cross-sectional descriptive study of 125 consecutive patients with phrynoderma attending the outpatient department (OPD) of dermatology was conducted in a tertiary care hospital. In all patients, a detailed history was taken and cutaneous examination findings such as distribution, sites of involvement, morphology of the lesions, and signs of nutritional deficiencies were noted., Results: The proportion of patients with phrynoderma attending the OPD was 0.51%. There were 79 males and 46 females. Age of the patients was in the range of 3-26 years with a mean of 10 ± 4.3 years. The lesions were asymptomatic in 114 (91.2%) patients. The distribution of lesions was bilateral and symmetrical in 89 (71.2%) patients. The disease was localized (elbows, knees, extensor extremities, and/or buttocks) in 106 (84.8%) patients. The site of onset was elbows in 106 (84.8%) patients. The lesions were discrete, keratotic, follicular, pigmented or skin colored, acuminate papules in all patients. Signs of vitamin A and vitamin B-complex deficiency were present in 3.2% and 9.6% patients, respectively. Epidermal hyperkeratosis, follicular hyperkeratosis, and follicular plugging were present in the entire biopsy specimen., Conclusion: Phrynoderma is a disorder with distinctive clinical features and can be considered as a multifactorial disease involving multiple nutrients, local factors like pressure and friction, and environmental factors in the setting of increased nutritional demand.
