[A rare cause of postpartum hemorrhage: a genital thrombus]. / Une cause rare d'hémorragie du post-partum: le thrombus génital.

Puerperal hematoma is a grave but fortunately rare hemorrhagic post-partum complication (occurring in less than 1:1000 deliveries). The hematoma arises due to detachment of para-vaginal conjunctive tissue. In this type of tissue, no natural hemostasis take place and the hematoma may spread into the retroperitoneal cavity. The different risk factors include primiparity, instrumental extraction of the foetus, pre-eclampsia, twin pregnancy and the presence of vulvo-vaginal varicose veins. External bleeding may not always be evident and other clinical symptoms may be delayed. Despite this, rapid course may still occur with drastic consequences. When a case is referred, an examination of the vulvo-vaginal region is mandatory, resuscitation and surgery performed immediately. If this fails angiographic embolization should be carried out. The prognostic outcome of this rare case of post-partum hemorrhagia is highly dependent on early diagnosis and rapid treatment involving close cooperation between obstetricians and anesthetists, and also of rapid embolization to prevent possible intractable hematomas.

[Angioneurotic edema and anesthesia: preparation and perioperative monitoring]. / Oedème angioneurotique et anesthésie: préparation et surveillance périopératoire.

Hereditary angioneurotic oedema is an autosomal dominant disease associated with serum deficiency of functional C1-inhibitor. It is characterized by periodic swelling of subcutaneous tissues, abdominal viscera and upper airways. Lethal acute episodes of oedema can occur during anaesthesia and surgery. It is essential to prepare such patients before surgery. This article describes three cases (kidney transplantation, caesarean section, normal delivery) and the various preventive measures used to avoid acute episodes during anaesthesia and surgery. Antibrinolytic agents, androgens, fresh frozen plasma, C1-inhibitor concentrate can be administered. Their various indications are discussed.

Biochemical study of the Feline Herpesvirus 1. Identification of glycoproteins by affinity.

Feline Viral Rhinotracheitis herpesvirus (Feline Herpesvirus 1; FHV-1) was purified by rate zonal isopycnic centrifugation. Viral nucleocapsids were isolated from the nuclei and purified. Analysis of the purified and radiolabelled viral polypeptides and glycoproteins by gradient SDS polyacrylamide gel electrophoresis revealed that 23 viral proteins and 6 glycoproteins were present in the whole virus particle. Tween 80-diethylether treatment removed the major glycoproteins. FHV-1 viral glycoproteins were detected using [14C] glucosamine and a lectin binding procedure. The fluorescein isothiocyanate-Concanavalin A (FITC-Con A) specificity was checked by trials on other viruses whose glycoproteins had already been described. The FITC-Con A allows a very simplified procedure for glycoprotein determination after slab acrylamide gel electrophoresis and can be used prior to Coomassie blue staining of proteins.
