[Single intrauterine fetal death in twin pregnancy].

During a 11 year period (1984-1994) we identified and analysed at the Department of Obstetrics, University Hospital of Zurich, among 541 twin pregnancies 19 with single intrauterine death (SIUD) in the second and third trimester. The preterm delivery rate was 68% and much higher compared to singleton pregnancies at the same institution (17%). The caesarean section rate was 47% and also higher compared to singleton pregnancies (21%) but lower than in a normal twin collective (61%).

[Influence of naso-sinusal anatomic variants on recurrent, persistent or chronic sinusitis. X-ray computed tomographic evaluation in 112 patients].

Using CT scan, we studied the influence of the most important sinonasal anatomic variants on 112 patients, aged more than 16 years, suffering from recurrent, persistent or chronic sinusitis. The series was characterized by the absence of: multifocal sinusitis, polyposis, dental or mycotic sinusitis, traumatic, tumour, actinic or prior surgery. We compared our results with those of the literature.

Uremic small-artery disease with medial calcification and intimal hyperplasia (so-called calciphylaxis): a complication of chronic renal failure and benefit from parathyroidectomy.

Background: Uremic small-artery disease with medial calcification and intimal hyperplasia can lead to life-threatening skin necrosis or acral gangrene. It is a distinct complication of chronic renal failure that must be differentiated from soft-tissue calcification. An increased calcium-phosphate product and secondary hyperparathyroidism are the main underlying conditions.

[Pregnancy after liver transplantation].

We present a case of pregnancy and delivery after liver transplantation. Even during pregnancy immunosuppression was maintained with cyclosporin (2 x 175 mg/day). The pregnancy was uneventful and there were no side effects of the cyclosporin therapy.
