One liver for two: an experimental study in primates.

The need for liver grafts is critical in countries where brain death is not accepted as a legal criterion for organ retrieval. This experimental study was conducted with nonhuman primates in order to evaluate the feasibility of liver transplantation using a living donor. An original technique was employed to remove the left part of the liver from the donor: transection of the parenchyma was done while the blood flow was kept to the left part of the liver. In the recipients, the graft was placed heterotopically. No blood transfusions were administered to donors or recipients. In spite of a few failures, due to consequences of intraoperative bleeding, several donor operations using this original technique were successful, in the immediate postoperative period as well as several months later. Among the recipients, the large number of early failures suggests that the heterotopic position is probably not the appropriate one and that orthotopic transplantation should be preferred.

[Purpura fulminans associated with a C7 deficiency].

A patient suffering from purpura fulminans was found to have a hereditary deficiency of the C7 component of complement. The homozygous deficiency of late acting complement components increases the risk of neisserial infection. CH50 titration will detect those patients suffering from a homozygous deficiency, who should be vaccinated against Neisseria meningitidis types.

Melanotic neurofibroma: a case report with ultrastructural study.

The authors report a case of a solitary melanotic neurofibroma involving the temporomalar area in a 17-year-old man. Light-microscopic study reveals a benign neurofibroma including melanin deposits. Electron microscopy shows typical premelanosomes and melanosomes within Schwann cell cytoplasm. The literature is reviewed, and theories of histogenesis for this unusual tumor are discussed.

[Riedel's thyroiditis and lymphoma. Diagnostic difficulties].

Two cases of Riedel's thyroiditis demonstrated the difficulties encountered in diagnosis. In the first case, subtotal thyroidectomy was performed due to compressive goiter. The intraoperative macroscopic aspect suggested Riedel's thyroiditis. The pathology report also discussed the diagnosis, despite a major lymphoid component, as dense fibrosis had multilated the thyroid parenchyma. Subsequent clinical course led to the diagnosis of lymphoma. The clinical presentation in the second case was classical with rapid increase in size of a hard thyroid gland. Histology was however atypical showing calcifications and liquid cysts within the fibrous thyroid tissue. The initial signs of Riedel's thyroiditis, a very rare disease, usually suggest neoplasia: ligneous compressive goiter with deep adherences. Histologically, there is invasive fibrous thyroiditis with highly suggestive occlusive phlebitis in certain cases. The origin of the disease remains obscure. The differential diagnosis between a sclerosing form and lymphoma is particularly important for therapeutic management.
