Efficacy of fluorescent microscopy versus modified Fite-Faraco stain in skin biopsy specimens of leprosy cases - a comparative study.

BACKGROUND: Histopathological examination of skin remains the cornerstone in the diagnosis of leprosy. At a few centers, fluorescent microscopy has been found to be useful in detecting more acid-fast bacilli (AFB) compared to modified Fite-Faraco staining but is sparsely documented. Hence, we studied the sensitivity of fluorescent microscopy and modified Fite-Faraco stain in the detection of Mycobacterium leprae in tissue sections. METHODS: Patients attending our outpatient department during January 2019 to June 2020 with the clinical features of leprosy were examined, and the diagnosis was confirmed by histopathology after informed consent. Tissue sections were stained by fluorescent stain and modified Fite-Faraco stain. Bacillary index was calculated for each case. RESULTS: Forty patients were recruited after following the inclusion and exclusion criteria. AFB were demonstrated in 20 patients by modified Fite-Faraco stain and in 27 patients with fluorescent stain. The sensitivity of fluorescent staining method (67.5%) was higher than modified Fite-Faraco stain (50%). Bacillary index was increased in 26 out of 40 cases by the fluorescent staining compared to the modified Fite-Faraco staining. Chi-square value was 69.3 and P value was 0.000, indicating a statistically significant correlation. LIMITATIONS: Fluorescent microscope is expensive, and trained people are needed to identify the bacilli. CONCLUSION: Fluorescent staining is more sensitive than modified Fite-Faraco staining in the detection of AFB in tissue sections. The bacilli detected per field were high with the fluorescent staining compared to the modified Fite-Faraco method.

Dermatoses Occurring after Parlor Procedures.

BACKGROUND: Cosmetic procedures are on the rise and practiced by all age groups, especially by teenagers. These procedures enhance the individual appearance and confidence levels, but they are not without side effects. AIMS AND OBJECTIVES: The aim of this study was to evaluate the side effects occurring after various parlor procedures such as facials, threading, waxing, and laser hair reduction. SETTING AND DESIGN: A prospective study for 12 months in a tertiary hospital. MATERIALS AND METHODS: Patients attending the department of dermatology at a tertiary care hospital for 12 months (July 2018-June 2019) were evaluated for any skin lesions, developed after one of the above parlor procedures. Detailed history, clinical examination, and correlation with the parlor procedure were noted. RESULTS: A total of 102 patients were found to have dermatoses after various parlor procedures during the 1-year study period (81 F and 21 M). Acneiform eruptions 26 (25.4%), followed by post-waxing folliculitis 17(16.7%), and hyperpigmentation of face 15 (14.7%) were the most common dermatoses. Molluscum contagiosum, verrucae plana, and tinea faciei were observed in 11, 6, and 3 patients, respectively. CONCLUSION: Side effects are not uncommon after parlor procedures. Awareness of these is necessary and educating the patients is extremely important to avoid these unwanted complications.
