Osteomyelitis due to Mycobacterium haemophilum in a patient with AIDS.
A case of osteomyelitis resulting from infection with Mycobacterium haemophilum in a patient with the Acquired Immunodeficiency Syndrome (AIDS) and Hodgkin's disease is described. The clinical features and response to therapy are examined and compared to previous reported cases. Mycobacterium haemophilum infection in immunocompromised patients usually results in cutaneous lesions but osteomyelitis may be the presenting feature. Tissue samples should be obtained early for microbiological examination and treatment should consist of surgical debridement and appropriate antimicrobial therapy.

Medullary thyroid carcinoma.
Medullary thyroid carcinoma is an infrequent and unusual malignancy. Since its description 15 years ago, many new features have developed. Many biologically active compounds which are directly related to the different symptoms of the disease have been recovered from the tumors. A familial incidence is noted, and there is an increased association with other tumors and their behavior. The cell of origin is the parafollicular cell, which secretes calcitonin and is responsible for the unusual behavior of medullary thyroid carcinoma. Treatment is primiarily surgical. Four cases are presented and the syndrome reviewed.
