Complications of closed capsulotomies after augmentation mammaplasty.

In a series of patients who underwent closed rupture of fibrous capsules surrounding mammary prostheses, 3 patients developed hematomas or rupture of the implant, with or without infection. These complications and their management are discussed. Closed capsulotomy is a valuable procedure, simple to apply and easy to learn, but it is not devoid of complications.

use of F(ab')2 fragment in experimental skin transplantation for burns.

In a series of experiments involving approximately 500 animals, burned rats were administered the F(ab')2 fragment of antidonor IgG to study the survival of incompatible skin allografts. No prolongation was noted when treatment consisted of antidonor F(ab')2 fragment alone. This was true whether the fragment was raised against donor spleen cells of donor skin, whether the skin allograft was partial or full thickness and whether the systemic treatment of the recipients was preceded by a period of incubation of the graft in F(ab')2 fragment or not. Significant prolongation of survival was noted when the fragment was raised against both donor and recipient histocompatibility antigen and when the donor skin was incubated in steroids as well as in F(ab')2 fragment prior to grafting. Additional findings included the confirmation of prolonged allograft survival by increasing burn size and the prolongation of allograft survival by the presence of intact eschar.

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.
