An under vacuum processing is able to procure a high mechanical resistance surface coating of few microns on rotating instruments. The results show an increase of the life expectancy of the instruments and an improvement of their mechanical qualities and their resistance to corrosion.

We report our personal experience of chronic ambulatory insulin therapy via portable and implantable pumps in insulin-dependent diabetics. Fifteen patients, poorly controlled on conventional insulin injections, were equipped with portable Siemens pumps. These pumps offer compactness, safety means, portability, one-month insulin reservoir and variable insulin rates. The pump catheter was chronically inserted in the peritoneal space using a non-surgical personal technique. Our present experience, representing six patient-years of treatment (range 1 to 16 months), shows excellent steady blood glucose control (mean blood glucose is 115 +/- 5 mg/dl v. 187 +/- 21 mg/dl with conventional therapy). All incidents were minor and most were catheter related. However, there was no catheter removal or discontinuation of pump treatment. All patients declared that there was a marked improvement in their quality of life. One of the pump-treated patients agreed to be transferred to a totally implantable Siemens prototype. The pump was inserted in the muscular wall of abdomen, and the delivery catheter terminated in the peritoneal space. Refills are made percutaneously approximately every 20 days. Rates and functions of the pump are remotely controlled. Five months after implantation, results, compared with those of a portable pump, show similar excellent blood glucose control and pump precision with a further improvement in the patient's quality of life. Thus, although further miniaturization and longer autonomy are expected in the forthcoming devices, our present experience shows that, with careful patient instruction and follow up, insulin pumps could represent in the next years an alternative to conventional insulin therapy for poorly controlled diabetics.
Following the setting up by the Government of their project for the management of drug addicts, and under the guidance of the CEIP (Centre d'Evaluation et d'Information sur les Pharmacodépendances [Centre for Evaluation and Information on Drug Addiction]) in Marseille, a survey of prescriptions written on controlled-drug prescription pads was performed. The aims were threefold: to study the medicines prescribed, to follow up the legislation and to inform doctors and pharmacists. Copies of the prescriptions, dated between 1 January 1996 and 30 June 1996, which were sent by 81 per cent of the 216 pharmacies contacted in 15 towns in the Provence-Alpes-Côte d'Azur (PACA) region were studied. Various criteria, relating to writing of the prescriptions and distribution of the medicines to the patients, were coded and analysed. This survey showed that of 4 prescriptions, 3 were prescribed for maintenance and one for analgesic therapy. The patients receiving maintenance therapy were male in three-quarters of the cases, and were around 30 years old. Analgesics were prescribed in equal proportions for patients of both sexes, who were around 65 years old. Since it was put on the market, Subutex has been quickly prescribed.
