Femoral and tibial fractures in a newborn calf after transplacental infection with bovine viral diarrhoea virus.

A one-week-old Brown Swiss calf had fractures of the metaphyseal regions of the left femur and right tibia, and a generalised, severe derangement of osteogenesis. Alternating zones of sclerosis and radiolucency in the metaphysis of all the long bones was visible radiographically. A histopathological examination revealed a segmental disruption of trabecular modelling, with subsequent fracture.

Chiasmal neuritis as a complication of Epstein-Barr virus infection.

A 13-year-old boy developed visual loss in association with an upper respiratory tract infection. Neuro-ophthalmologic examination indicated a lesion at the junction of the right optic nerve and chiasm. Laboratory investigation and subsequent serologic studies demonstrated recent Epstein-Barr virus infection, suggesting an association of chiasmal optic neuritis with Epstein-Barr virus infection.

Intravascular, bronchiolar, and alveolar tumor of the lung (IVBAT). An analysis of twenty cases of a peculiar sclerosing endothelial tumor.

Twenty cases of an unusual tumor of the lung are described. This tumor usually presents with multiple small, slowly growing pulmonary nodules. Many cases are detected incidentally.

Subacute combined degeneration of the spinal cord with cystinuria.

An 18-year-old man had noticed increasing difficulty in walking for 4 years. Examination disclosed spastic paraparesis and posterior column signs suggestive of subacute combined degeneration of the spinal cord. Urinalysis, urinary thin-layer chromatography, and intestinal biopsy disclosed typical cystinuria.
