RESUMEN
La enfermedad por arañazo de gato (EAG)es una enfermedad infecciosa, producida por Bartonella henselae, de curso benigno, que se presenta frecuentemente como adenopatía crónica en niños. En un 5 a 25 por ciento se puede manifestar de forma atípica, con compromiso óseo, abdominal, neurológico y oftalmológico. Presentamos 3 casos de EAG de curso atípico, con compromiso óseo confirmado con cintigrafía ósea y serología positiva para Bartonella henselae. Después de tratamiento antibiótico se obtuvo completa mejoría clínica.

Rhinosporidiosis was the commonest (68%) fungal lesion encountered during the period of 11 1/2 years from January 1987 to July 1998. Men in 2nd, 3rd, 4th decade were commonly affected. Nose and nasopharynx were the commonest (85%) sites involved followed by ocular tissue (9%). One patient had involvement of bone (tibia). Generally a lymphoplasmacytic response was observed in all cases. Polymorphonuclear leukocytic response mostly observed at the site of rupture of sporangia. Epithelioid cell granulomatous and giant cell response observed in 47% of cases. Transepithelial migration of sporangia observed in 76% of cases. Rhinosporidium seeberi could be easily identified in haematoxylin and eosin stained sections. The walls of young trophic forms are delineated well with the PAS stain and verhoeff van Gieson stain.

A young man presented with multiple Subcutaneous nodules over scalp, hand, feet and osteolytic lesions of small bones of hand. Clinically and radiologically he was diagnosed as a case of Giant Cell Tumour. Aspiration cytology and biopsy proved it to be rhinosporidiosis. Epidemiological study revealed that he perhaps contracted this infection as an occupational hazard. This is the third reported case of osteolytic lesions due to rhinosporidiosis. Diagnostic dilemmas of subcutaneous and osteolytic rhinosporidiosis are discussed.

The prevalence and role of anaerobic bacteria in bone infection were investigated in this prospective study on 134 cases with pyogenic osteomyelitis. Specimens were inoculated immediately in the operating theatre or in the ward and incubated under aerobic and anaerobic conditions without using transport media. Anaerobic organisms were isolated from 39 of the 134 cases [29%] of all types of pyogenic osteomyelitis. The total number of aerobic and anaerobic isolates was 224, of which 50 were anaerobes [22%]. Syringe-aspirated specimens were better than swab specimens for the isolation of anaerobes. Anaerobes were mostly isolated from osteomyelitis cases of long duration
