Unraveling the realities of vascular access: the Network 11 experience.

Arteriovenous (AV) fistulae are well recognized as the preferred vascular access for hemodialysis, yet national data show that only 23% of patients used an AV fistula in 1997. To identify barriers to the placement of native AV fistulae, the Renal Network of the Upper Midwest, Inc. (End-Stage Renal Disease [ESRD] Network 11) initiated a vascular access project to look at the process of referral for patients beginning hemodialysis in the first 6 months of 1999. Of these patients, 63% began hemodialysis with a catheter as the only access, 22% had an AV fistula placed (but only 14% used an AV fistula for their first dialysis treatment), and 15% began with a graft. About 40% of patients were referred to a nephrologist less than 1 month before dialysis, allowing little chance for permanent access placement. Yet 27% of patients used a catheter on the first hemodialysis treatment and were seen by a nephrologist more than 1 month before starting dialysis, indicating the presence of an opportunity to improve. At 6 months after initiation of dialysis, 25% of patients who began dialysis using a catheter were using an AV fistula and 35% were using a graft. Network 11 plans to use this information to promote early referral of patients to a nephrologist and subsequent prompt referral of such patients to a vascular surgeon. Other activities to improve vascular access management are also indicated.

The Internet and poverty: real help or real hype? Panos Briefing No. 28.

Governments, donors and development organisations are rushing to realise the benefits that Internet access promises in the fight against poverty. But are the benefits it has brought so far merely isolated examples or are they signs that a revolution is underway? Access to information is an essential condition of development. The Internet has prompted a change in development thinking and many donor and multilateral lending organisations are radically reshaping their policies for the new information age. But is the enthusiasm among donors for spending on Internet development diverting funds from more traditional forms of development assistance? In terms of its most adaptive component, the World Wide Web, the Internet is still only four years old. Real hype or real help? The jury is still out. Quite simply, it is still too soon to tell.

In situ degradation of 11/0 polyester (mersilene) suture material following cataract surgery.

Two hundred and ten patients (231 eyes) had their cataract sections closed with 11/0 polyester suture material over a 4 year period. Their case sheets were assessed to determine the number of eyes from which sutures had been removed prior to discharge, and for what reasons these sutures were removed. Ninety-seven patients (107 eyes) with sutures left in situ were further assessed to determine whether they were suffering from any suture-related symptoms and examined to determine the degree of clinical biodegradation experienced by the sutures. Six of these sutures were removed for electron microscopic examination. Of the 231 eyes initially included, 61 sutures (26.4%) had been removed prior to discharge. None of the 107 sutures examined showed evidence of clinical biodegradation; this was confirmed by electron microscopic analysis which showed only minimal erosion of sutures even after 48 months in situ.
