There are very few data on the prevalence of coccidian enteric parasites among low-income adults hospitalized in Chennai, India. Stool samples from 200 patients were screened for selected parasites, enteric bacterial pathogens, and other protozoa over a 3-month period. The study identified 42 (21%) Cryptosporidium, 36 (18%) V. cholerae, 17 (9%) Salmonella, 12 (6%) Isospora, six (3%) helminths, five (3%) Shigella, one (1%) Cyclospora, one (1%) other protozoan, and 0% V. parahaemolyticus cases. Co-infection was present in 21 patients. Cryptosporidium was detected in 17 (81%) of co-infected patients. Our findings highlighted the relatively high proportion of patients in this population with Cryptosporidium and Isospora and suggest that further study be undertaken to determine the utility of broader use of diagnostic testing for coccidian parasites in India. Detection may be beneficial because isosporiasis is treatable and both Isospora and Cryptosporidium are important pathogens in AIDS patients.

A tenosynovial giant cell tumor (TGCT) is a benign lesion whose presence in Hoffa's pad has rarely been reported. This unique case report discusses a 33-year-old female patient who presented with swelling and pain in her left knee. Clinical and MRI findings were used to make the diagnosis, which was confirmed on a histopathological basis. The patient had a large tumor (5 × 3 × 3 cm) in Hoffa's fat pad, which was diagnosed as TGCT and managed with open resection due to its size. At follow-up after 20 months, the patient was asymptomatic, and there was no local recurrence of the tumor.
