Heterozygous protein C deficiency and coumarin necrosis of the skin.

An obese female patient aged 47 with a personal and familial history of recurrent venous thrombosis, who developed a coumarin-induced skin necrosis is presented. Laboratory investigations, performed three months after the acute event and in absence of coumarin therapy, emphasized a decreased anticoagulant activity of her plasma protein C (50% of the normal). These results as well as the high incidence of thrombotic disease in her relatives point to a familial heterozygous protein C deficiency. The antithrombotic role of the protein C system and the mechanism of coumarin induced necrosis of the skin are briefly discussed.

The authors analyse, retrospectively, the experience of the Clinic of Surgery III. Cluj-Napoca, in the indications and surgical methods for reintroducing the duodenum in the digestive circuit in the syndromes of the stomach operated for benign affections. Between 1974 and 1987, the duodenum was reinstated in the digestive circuit in 37 patients, operated previously for duodenal ulcer (32 cases), gastric ulcer (3 cases), syndrome of mesenteric clip (2 cases). The primary surgeries that led to the exclusions of the duodenum from the digestive tract were gastroenteroanastomosis in 4 cases, and the gastric resections with gastrojejunal anastomoses of the Billroth II type in 33 cases (Reichel-Polya in 28 cases. Hoffmeister-Finsterer in 3 cases, Roux in 2 cases). The reintroduction of the duodenum in the digestive circuit, based on clinical and paraclinical criteria, was indicated in anastomotic ulcer (in 17 cases), gastric ulcer following gastroenteroanastomoses (in 1 case), syndrome of afferent loop (in 11 cases), persistent "dumping" syndrome (in 8 cases), association of plurideficiency syndrome (in 54% of the cases). The way of reconstructing the duodenum was adapted to the type and correctness of the primary operation, to the dominant clinical syndrome and associated lesions to the biological background and possibilities offered by the intrasurgical situation: reconversion by direct gastroduodenal anastomosis after degastrogastrectomy was used in 31 cases, the indirect methods by transposition of the afferent loop (Soupault--Bucaille) in 4 cases, or of the afferent one (Henley)--1 case gastrography and segmentary enterectomy in 1 case. The postoperative complications appeared in 35.1% of case, with a mortality of 8.1%. The therapeutic results were good and very good in 89.3% of the cases. The authors insist on the importance of maintaining the duodenum in the digestive circuit, during the primary surgeries for preventing some severe postsurgical syndromes.
