[Bilateral femoro-popliteal acute recurrent arterial thrombosis in the course of heparin-induced thrombocytopenia (white thrombus syndrome)]. / Trombosi arteriosa acuta recidivante femoropoplitea bilaterale in corso di trombocitopenia indotta da eparina (sindrome da trombo bianco).

Heparin induced thrombocytopenia with thrombosis, or the "white clot syndrome" is a rare but very important complication of heparin therapy. The syndrome is idiosyncrasic, immune-mediated and not dose dependent and therefore is equally likely to occur with prophylactic and therapeutic heparin dosage regimens. We report a typical case of HIT that occurs with prophylactic heparin therapy and results in bilateral amputation of the lower limbs. We discuss this important condition and some guidelines on its prevention and treatment.

[Herniation of the cecum and ascending colon through Winslow's foramen and the lesser omentum. A case report]. / Erniazione del cieco e colon ascendente attraverso lo iato di Winslow e il piccolo omento. Presentazione di caso clinico.

Internal hernia into epiploic foramen is a rare clinical entity, representing 1% of all herniae and 8% of internal herniae. We report a peculiar case of internal herniation presented during a laparotomy for acute colecystitis where the caecum and ascending colon entered the lesser sac through the forame of Winslow and reentered the main abdominal cavity through a congenital defect of the lesser omentum.
