Effects of glycopyrrolate and cimetidine on gastric volume and acidity in patients awaiting surgery.
Glycopyrrolate or cimetidine was administered before operation to patients undergoing elective surgery. After the induction of anaesthesia, the stomach contents were retrieved and the volume and pH measured. Neither drug diminished the volume of gastric contents compared with control. Glycopyrrolate produced little diminution in hydrogen ion concentration. Cimetidine caused a marked increase in pH with a mean [h+] 3.2 x 10(-3) g litre-1 compared with 1.4 x 10(-2) g litre-1 in the controls and 1.1 x 10(-2) g litre-1 in the glycopyrrolate group. Seventy-seven per cent of the patients receiving cimetidine had a pH greater than 2.5.

Laparoscopic sterilization with electrocautery, spring-loaded clips, and Silastic bands: technical problems and early complications.
Among 2283 patients, rates of technical failure, technical difficulty, and operative and early postoperative complications were evaluated for different methods of tubal occlusion at laparoscopy: electrocoagulation (980 cases), spring-loaded clip application (991 cases), and Silastic band application (312 cases). Rates of technical failure and technical difficulty at surgery were significantly higher (P less than 0.05) for the spring-loaded clip technique than for the electrocoagulation and Silastic band techniques. Mechanical and optical difficulties with the prototype spring clip applicator were the major sources of technical difficulties. Rates of operative (1.2%) and early postoperative (1.9%) complications were not significantly different for the three techniques of tubal occlusion. It is concluded that all three study techniques appear to be practical, and large, long-term, randomized, comparative studies to determine rates of failure and subsequent gynecologic problems are necessary to determine the best method of sterilization.

Gram-negative identification card for identification of Salmonella, Escherichia coli, and other Enterobacteriaceae isolated from foods: collaborative study.
Twelve laboratories evaluated the Gram-Negative Identification (GNI) Card to identify members of the Enterobacteriaceae. Eighty-four isolates, previously isolated from foods, were used in the collaborative study; the isolates represented 12 genera within the Enterobacteriaceae group. Each collaborator streaked each isolate on tryptic soy agar plates for purity. In the method, plates are incubated 18-24 h at 35 degrees C. Isolated colonies are then subcultured to tryptic soy agar slants and incubated 18-24 h at 35 degrees C. An emulsion is made from the growth on the slant in 1.8 mL 0.45% sodium chloride solution. The GNI Card is filled and placed in a reader/incubator. Isolates are identified and an identification is printed. The Vitek System correctly identified 96.7% of Salmonella sp., 97.0% of Escherichia coli, and an average of 93.8% of the other enteric genera. The method using the Vitek System and GNI Card has been approved interim official first action by AOAC as a screening method for the presumptive identification of Salmonella sp., E. coli, and other Enterobacteriaceae isolated from foods.

Industry perspectives on Listeria monocytogenes.
Industry concerns and our ongoing research on Listeria are discussed in this report. Topics include sampling for analysis; sanitizers and their use in manufacturing facilities; precautions on use of the FDA method for Listeria; use of the Vitek Gram Positive Identification Card; and a brief discussion on findings of Listeria in environmental samples taken from the same site at the same time of year in 1986 and 1987.

Intradural lumbar disk fragment with ring enhancement on MR.
Intradural extension of a herniated intervertebral disk, an unusual complication of a common disease, may mimic an intradural tumor on MR. A case of a pathologically proved subdural disk fragment is presented; MR findings that suggested the correct diagnosis were: proximity of intervertebral disk disease; whorl-like mixed intensity on T2-weighted images; poor visualization of the mass on unenhanced T1-weighted images; and marked ring enhancement following administration of gadolinium.
