[Carotid endarterectomy with placement of a PUR (polyurethane) patch].

In this study, 40 patients who underwent surgery for cerebro-vascular insufficiency were considered. Carotid endarterectomy was the procedure of choice in all of the patients; the arteriotomy was always closed using a PUR patch, a new material that, for its chemical and physical characteristics seems to be a good alternative to PTFE. All of the patients underwent surgery under loco-regional anesthesia, allowing a perioperative monitoring of the neurological status through the patient's active collaboration. During the postoperative period, non local or systemic pathology related to the use of the patch has been observed. During the short and half term follow-up, the patients underwent echo-Doppler of the supra-aortic trunks that didn't show either false aneurysms or thrombosis on the patch surface.

Evaluation of a semipermeable polyurethane absorptive dressing.

While semipermeable film dressings are well established for treatment of moist wounds, they lose moisture to the atmosphere at a fixed rate. This article reports an evaluation of a semipermeable dressing recently made available in the UK which claims to vary the rate of moisture vapour loss.

Treatment of esophageal fistulas with a new polyurethane-covered, self-expanding mesh stent: a prospective study.

OBJECTIVES: Esophagorespiratory fistulas are serious complications of malignant disease in the esophagus and are associated with rapid deterioration and death. Palliation has thus far consisted of insertion of a plastic stent to occlude the fistula opening. Insertion of these stents is associated with a high complication rate. Our aims were to study the efficacy of a new class of metal stents covered with a membrane with regard to fistula occlusion and lumen patency. METHODS: Six consecutive patients with esophagorespiratory fistulas were treated with covered expandable metal stents. RESULTS: In all six patients, no evidence of persisting fistula was seen on contrast radiographs 2 h after stent placement. All patients were able to eat a normal diet after stent insertion and had complete occlusion of their esophagorespiratory fistula. One patient reported pain after the procedure, and the symptoms persisted until death. One patient died of massive hematemesis 5 days after the procedure. Dysphagia scores improved in all patients from a median of 4 to a median of 1, and the Karnofsky score improved from a median of 40% to a median of 65%. Fistulas remained closed until death in all patients. CONCLUSIONS: Covered expandable metal stents are safe and effective in the palliation of esophagorespiratory fistulas.

Preliminary comparison of the polyurethane female condom with the latex male condom in Kenya.

This paper summarizes acceptability data published to date on the innovative female condom, and presents an additional study comparing the acceptability of the female condom and the latex male condom in a sample of low risk women attending private obstetrician/ gynaecologists' clinics in Nairobi, Kenya. Eighty-four percent of all subjects who completed interviewer-assisted questionnaires reported that they liked using the female condom, and more than two-thirds of all the women liked the female condom as much or better than the male condom. Fifty-five percent of the women would use the device in future if it were available. The least liked features were that the device was too large for easy insertion, messy to handle, and reduced sensation. Use became easier and more comfortable with experience. The most liked features were that the device made sex more enjoyable, protected against sexually transmitted diseases and pregnancy, and was under the woman's control. Male partner response was slightly less favourable, and sometimes resulted in women's noncompliance or discontinuation of use, despite the fact that such a device is supposed to empower women. This study provides preliminary data indicating that the female condom is a fairly acceptable method for some Kenyan couples, but recommends further research into safety, cost-effectiveness and hindrances to acceptability.
