RESUMO
Chest wall tuberculosis is a very rare clinical entity that accounts for 1-5% of musculoskeletal tuberculosis (TB). Here we present a case of chest wall TB. A 16-year-old boy presented with complaints of progressive increasing swelling over the right hemithorax following a history of trauma. Radiologically it was a localized liquid collection with no connection to the thoracic cavity. Pus sample was sent to the mycobacteriology laboratory. The Gene Xpert result came as positive, and sensitive to rifampicin while the acid-fast bacilli (AFB) smear test was negative. Diagnosing a case of chest wall TB is always challenging for clinicians.

INTRODUCTION: Aspergillus species are ubiquitously found in the environment worldwide and are important causative agents for infection. Drug resistance among Aspergillus species is emerging, hence the present study was undertaken to look for antifungal susceptibility profiles of clinical and environmental isolates of Aspergillus species. MATERIALS AND METHODS: During the period from January 2018 to June 2019, a total of 102 Aspergillus isolates (40 clinical, 40 hospital, and 22 community environment) were tested for antifungal susceptibility testing for determination of minimum inhibitory concentration (MIC)/minimum effective concentration (MEC) as per Clinical and Laboratory Standards Institute (CLSI) M38-A3 method for itraconazole, voriconazole, amphotericin B, and caspofungin. RESULTS: Out of these 102 Aspergillus isolates, A. flavus was the most common species present. Aspergillus species were found to have low MIC values to azoles such as itraconazole and voriconazole except for one clinical isolate, which showed a MIC value of 2 µg/ml to voriconazole. Two isolates were non-wild-type for amphotericin B, but all isolates were wild-type for caspofungin. CONCLUSION: Antifungal susceptibility testing among clinical Aspergillus isolates and environmental surveillance studies in view of emerging drug resistance should be undertaken at a larger scale.
