A new procedure for management of extrahepatic portal obstruction. Proximal splenic-left intrahepatic portal shunt.

For management of obstruction of the extrahepatic portal trunk in patients with healthy livers, we designed an end-to-side anastomosis between the proximal splenic vein and the umbilical portion of the left intrahepatic portal vein and performed a splenectomy to relieve portal hypertension, treat hypersplenism, and restore hepatic portal flow. To our knowledge, no other procedure more adeptly restores original hepatic blood flow. Creation of an anastomosis between the coronary vein and umbilical portion of the left intrahepatic portal vein is an alternative method.

Carcinoid tumor localized in the liver--two cases report: immunohistochemical and ultrastructural studies.

Two cases of carcinoid tumors, considered to be probably hepatic in origin, occurring in a 53-year-old man and a 69-year-old woman are reported. In both cases no endocrine syndrome appeared, and an alternative primary source of the tumor was not found in case two, despite an intensive search at operation. The neoplasms in both cases were soft, firm, brown-pink and well-encapsulated. They were composed of small uniform cells, that had distinct borders and grew in insular, nests, trabeculae and strands that were separated by a delicate fibrous stroma. Stains of argentaffin and argyrophil showed strong positivity in both cases. The immunohistochemical and ultrastructural studies all demonstrated characteristics of a carcinoid. The postoperative recovery was good. They have remained well 5 years later in case 1 and 3 years in case 2 after surgical treatment. Literature concerning this rare condition is also reviewed.

Inflammatory pseudotumor of the liver with occlusive endophlebitis: report of a case.

Inflammatory pseudotumor (IPT) of the liver is an extremely rare benign tumor. Only 12 cases have so far been reported in the English literature. The etiology and pathogenesis of IPT remain obscure. We herein present an additional case of IPT of the liver with occlusive endophlebitis in a 36-year-old female. Immunohistochemical studies demonstrated the polyclonal nature of the plasma cells in the tumor, including IgA, IgM, IgG, kappa and lambda. The inflammatory pseudotumor should be kept in mind in the differential diagnosis of hepatic space-occupying malignant lesions.

Inflammatory pseudotumor of the spleen--case report and literature review.

Inflammatory pseudotumor (IPT) of the spleen is an extremely rare benign lesion. We herein report an additional case of a 64-year-old man with IPT of spleen to compare with seven cases previously reported in the literature. However, the immunohistochemical studies has demonstrated to polyclonality of plasma cells which was comparable to these seven previously reported cases. The clinical and pathological findings, as well as the possibilities of etiology and pathogenesis are also described.

Adaptive housing: remodeling considerations for the disabled.

The disabled are handicapped only to the extent that they are prevented from being normal. The process of normalization is hampered by physical barriers in the home that make life difficult for disabled persons. Staff can be trained to eliminate these architectural barriers in the home, focusing primarily on accessibility, the bathroom, the bedroom, and the kitchen. Completion of the barrier-free design of the home should provide a cost-effective means for improving the quality of life for disabled persons and their families.

A system for adaptive transportation.

In our society, we take for granted the ability to travel with few restrictions. For most travelers, the major factor that limits travel is cost. However, for a significant number of Americans, the phrase "freedom to travel" is meaningless. These are the physically handicapped, a group with special needs that has long been denied what every American assumes to be a natural right.
