RESUMO
This case series sheds light on the pulmonary diseases afflicting artisanal gold miners in Chunya district, Mbeya, Tanzania. We present 3 cases from a group of 21 miners. The patients, ranging in age and mining exposure, exhibited symptoms of severe pulmonary conditions, including pneumoconiosis, pulmonary hypertension and Cor pulmonale, attributed to prolonged exposure to dust and inadequate protective measures in mining environments. These cases underscore the urgent need for enhanced occupational health standards and preventive strategies in artisanal mining communities.

The aim of this study was to determine the entrance surface air kerma (ESAK) in adult patients during digital radiography and to evaluate the optimisation potential in five common X-ray examinations in Tanzania. Based on a sample of 240-610 patients, ESAK was estimated using X-ray tube output measurements, patient information and backscatter factors. The results show that the mean ESAK values were higher or comparable to data from the literature. The diagnostic reference values of ESAK for digital radiography were 0.31 mGy (chest PA), 4 mGy (lumbar spine AP), 5.4 mGy (lumbar spine LAT), 3.8 mGy (abdomen AP) and 2.4 mGy (pelvis AP). For computed radiography, the mean ESAK ranges were 0.44-0.57 mGy (thoracic AP), 3.59-3.72 mGy (lumbar spine AP), 6.16-6.35 mGy (lumbar spine LAT), 3.89-3.44 mGy (abdominal AP) and 2.92-3.47 mGy (pelvic AP). In conclusion, high ESAK variations show the potential for optimising protection in digital radiology.

Tuberculosis in endemic areas is likely to be overdiagnosed in patients with atypical clinical and imaging findings mimicking tuberculosis, as in our case of angiosarcoma. Detailed history, physical examination, imaging, and histopathology avert diagnosis of tumors as tuberculosis in resource-limited settings, where countless diseases have common clinical and imaging presentations.
