A clinical prevalence of dermatophytic mycoses with an assessment of its clinical manifestations in a tertiary care hospital at Salem, South India.

BACKGROUND: Dermatophytosis is very common among all age groups throughout the world. The incidence of the same is increasing on a steady basis. AIM: Estimating the clinical prevalence of dermatophytes mycoses among the patients visiting the outpatient unit and assessing its distinct manifestations. METHODOLOGY: A prospective observational study was conducted with the patients attending the Skin and STD outpatient unit of a tertiary care teaching hospital in Salem. A total of 3068 outpatients attended the department, of which 420 patients were diagnosed with dermatophytic mycoses and were taken for investigating the prevalence. RESULTS: A total of 420 dermatophytosis patients were included giving a percentage prevalence of 13.69%. There were more female patients (n = 213, 50.71%) than males (n = 207, 49.29%). The most common afflicted age group was 31-40 years (n = 99, 50.71%). Most of the patients had an atypical lesion called tinea incognita (n = 265, 63.09%) where there was no typical classic appearance of dermatophytic infections. The most prevalent clinical manifestation was tinea corporis (n = 73, 17.38%) followed by tinea cruris (n = 69, 16.43%). There were more newly diagnosed dermatophytosis cases (n = 326) than the previously diagnosed cases (n = 94). CONCLUSION: This study concludes that dermatophytic mycoses were more prevalent among females than males and among the age groups of 31-40 years. The most common clinical presentation was tinea incognita followed by tinea corporis.

A clinicoepidemiological study on tinea incognita with assessment of its treatment strategies and drug prescribing practices in a tertiary care hospital.

BACKGROUND: The incidence of tinea incognita (TI) appears to have increased over recent years owing to the easy availability of topical corticosteroids as over-the-counter preparations. AIM: Describing the various clinicoepidemiological aspects of TI and assessing the treatment strategies and prescribing practices followed for its management. MATERIALS AND METHODS: A prospective study was conducted with 170 patients in the department of Skin and STD of a tertiary care hospital at Salem from Jan 2022 to June 2022. The various sociodemographic information was obtained by interviewing the patients and a detailed dermatological examination was performed by the dermatologists to describe the morphology of lesions, and sites involved. RESULTS: The results were statistically analysed and expressed in the form of percentages. Most of the patients were in the age group of 41-50 years. The majority of patients were illiterate, unskilled workers, married, belonging to the lower middle class, from rural localities, and with positive family histories. Most of the patients were suffering from TI for more than 1 year. The commonly used treatment modality was combinational therapy which comprises oral and topical antifungals and antihistaminic drugs. The commonly prescribed antifungal was itraconazole. CONCLUSION: This study emphasises the need to spread awareness among the pharmacist and the community regarding the adverse consequences of practicing self-medication with topical corticosteroids.

Therapeutic exploration of polyherbal formulation against letrozole induced PCOS rats: A mechanistic approach.

Objective: This study aimed to develop an effective alternative medicine with multi potential herbs against polycystic ovarian syndrome (PCOS) in rats induced by letrozole treatment. Materials and method: Polyherbal syrup was prepared with a combination of S. asoca bark, G. sylvestre leaves, P. daemia aerial parts, C. zeylanium stem bark, C. bonduc seeds, and W. somnifera roots ethanolic extract. In vitro cell viability study, adenosine monophosphate-activated protein kinase (AMPK), and glucose transporter 4 (GLUT4) gene expression assay were carried out on the Chinese Hamster Ovarian (CHO) cell line. For the PCOS induction letrozole (1 mg/kg p. o.) was given for 21 consecutive days. The PCOS induction was confirmed by measuring estrus irregularity, insulin resistance by oral glucose tolerance test (OGTT), and hyperandrogenism by measuring serum total testosterone level 21 days after completion of letrozole treatment. After induction of PCOS, metformin (155 mg/kg p. o.), and polyherbal syrup (100 mg/kg, 200 mg/kg, and 400 mg/kg p. o.) were administered for further 28 days. The treatment efficacy was measured by measuring serum lipid profile, fasting insulin level, sex hormones level, ovarian steroidogenic enzymes, ovarian tissue insulin receptor, AMPK, and GLUT4 protein expression levels, and histomorphological studies. The post-treatment effect was confirmed by reproductive performance studies. Results: Letrozole-induced PCOS rats showed significant estrus irregularity, abnormal sex hormones levels, and hyperandrogenism indicated by showing increased free androgenic index and decreased sex hormones binding globulin (SHBG) level. The insulin resistance in PCOS rats was indicated by increased fasting glucose levels with impaired glucose clearance in the OGT test. Homeostasis Model Assessment Index of Insulin Resistance (HOMA-IR) increased level, also decreases INSR, GLUT4, and AMPK mRNA expression in ovarian cells confirming the insulin resistance in PCOS rats. Ovarian histology in PCOS rats also showed many follicular cysts, atretic follicles, and the absence of corpus luteum. The administration of polyherbal syrup, in a dose-dependent manner, effectively restored these alterations. The treatment of polyherbal formulation 400 mg/kg possesses highly significant efficacy over the treatment of metformin in PCOS rats. It mainly acts by reducing peripheral and ovarian hyperandrogenism and improves insulin sensitivity via activating the insulin receptor and AMP-activated kinase-mediated transcription and translation of GLUT4 from the cytoplasm to the ovarian membrane improves glucose uptake and promotes the follicular development and ovulation. The higher fertility rate, delivery index, and survival of delivered pups confirm the broader and superior efficacy of PCOS. These beneficial actions are mainly attributable to the formulation's inclusion of the key secondary metabolites flavonoids and phytosterols. In conclusion, the prepared polyherbal syrup was found to be the safest and most effective alternative medicine for both endocrinal and metabolic complications of PCOS women.
