Research in reduced suture fibrin glue (FG) and sutureless FG anastomosis has been lagging behind FG utilization in other surgical fields. A review of the literature for vascular, esophageal, tracheal, gastrointestinal, common bile duct, ureteral, vas deferens, and Fallopian tube FG anastomosis indicates that reduced suture FG and sutureless FG procedures may be performed with less training, reduced operating time, leakage, ischemia, inflammation, and necrosis compared to sutured techniques. Reduced suture FG vascular anastomosis augments early anastomotic strength. Suture number for esophageal, tracheal, and tracheobronchial anastomoses can be reduced with FG. Bursting strength in pig small intestine and rat colon was lower at 4 days postoperatively, but returned to sutured strength at 7 days. Mortality was unaffected, and 18-month follow-up in sutureless FG intestinal anastomosis in pigs showed no stenosis. Preliminary ureteral studies have demonstrated successful sutureless FG and reduced suture FG laparoscopic techniques in pigs. Reduced suture FG and sutureless FG vas deferens anastomosis may reduce sperm granuloma rates, with increased patency and pregnancy rates. Patency and pregnancy rates have been similar for tubal FG, reduced suture FG, autologous fibrin glue (AFG), and sutured anastomosis. Any risk of viral transmission or immune response is eliminated by AFG. While there are few studies in many areas of FG hollow vessel anastomosis, the current literature illustrates many of the advantages of FG over other anastomotic techniques and should provide impetus for continued research in this promising field of surgery.

Two severely burned patients experienced the onset of marked hyperosmolality during topical treatment with a cream containing silver sulfadiazine as an antimicrobial agent. Serum samples from both patients were studied for the presence of substances absorbed from the vehicle of the cream. Prophylene glycol, in concentrations which were high enough to account for the difference between calculated and measured osmolality, was demonstrated in the sera of these patients by gas chromatography.

The SAINT-PD has potential for all gastrointestinal sites, but needs larger experimental trials. The SS technique is impractical and had high tissue ridge formation and adhesion rates. These preliminary trials suggest the simplicity, versatility and safety of the SAINT technique; however, the small groups limit result interpretation. The results present a starting point for sutureless FG gastrointestinal anastomosis, and future experimental evaluation with more extensive statistical analyses in larger studies are needed.

Ammonia, methylamine, and pyridine were detected in broth filtrates of a streptomycin-degrading strain of Pseudomonas maltophilia during growth on streptomycin as a sole carbon and nitrogen source. Ammonia and methylamine, quantitatively measured by conversion to chromophores with picryl sulfonic acid, were found to accumulate in broth, whereas pyridine concentration increased in the early stages of streptomycin degradation and then decreased as the degradation of the antibiotic neared completion. Exogenous pyridine was metabolized by washed-cell suspensions. Use of N-streptomycin-methyl-14C showed that the methylamine arose from the N-L-glucosamine-methyl moiety of streptomycin. Methylamine was an end product and was not further metabolized by cells.
