Pneumococcal glomerulonephritis is rarely described in the literature. We report a four-year-old boy who developed acute glomerulonephritis following pneumococcal bacteraemia and submandibular lymphadenitis, and review the published literature. Two weeks after developing acute glomerulonephritis, the patient developed bronchopneumonia with left pleural effusion. However, by the fourth week of admission, his renal function had normalised and lung involvement resolved.

We report a case of cat scratch disease in an 8-yr-old girl who presented with fever and enlargement of both axillary lymph nodes. Both aerobic and anaerobic cultures of the lymph node aspirate were negative for microbial growth. Gram staining and Warthin-Starry silver staining did not reveal any organism. Purified DNA from the PCR-amplicon of the 16S-23S rRNA intergenic region was sequenced and showed 99.7% identity with the corresponding sequence of Bartonella henselae strain Houston-1. Our findings suggest that the internal transcribed spacer is a reliable region for PCR identification of Bartonella species. In patients with lymphadenitis, a history of contact with cats or dogs necessitates the use of diagnostic approaches that employ not only the conventional staining and culture but also molecular methods to detect B. henselae.

Cryptococcal infection is a rare, yet well recognized complication of systemic lupus erythematosus (SLE). We present a case of mesenteric and retroperitoneal cryptococcal lymphadenitis resulting in the obstruction of the stomach and proximal duodenum in a patient suffering from SLE, while recently she did not receive any immunosuppressive treatment. A 42-yr-old woman was admitted due to high fever and diffuse abdominal pain for three weeks. Abdominal computed tomography (CT) scan showed multiple conglomerated lymphadenopathies in the retroperitoneum and the mesentery resulting in luminal narrowing of the third portion of the duodenum. Cryptococcal lymphadenitis was proven by needle biopsy and she was treated with intravenous liposomal amphotericin B, followed by oral fluconazole. After fourteen-month antifungal therapies, the clinical symptoms and follow-up images improved. This case emphasize that the intrinsic immunological defects of SLE may be directly responsible for the predisposition to fungal infections.
