Suicidal behavior among young people in Singapore.

The purpose of this study was to investigate suicidal behavior among young people in an Asian community. Tracing records of all patients below 21 years of age who attempted suicide and were managed in a teaching hospital, the authors found the incidence increased sixfold between 1991 and 1995. Young females of Indian origin were found to be a risk group. Differences in suicidal behavior among the three main ethnic communities appear to be influenced by various sociocultural factors. The most common diagnosis was adjustment disorder stemming from interpersonal losses and conflicts. Schizophrenia, alcohol, and other substance abuse were rarely reported.

Effects of postoperative mitomycin C on glaucoma filtration surgery in rabbits treated preoperatively with antiglaucoma medications.

In a rabbit model, we evaluated the effects of topically applied postoperative mitomycin C (MMC) on the success rate of glaucoma filtration surgery in animals treated preoperatively with pilocarpine hydrochloride 4% and levobunolol hydrochloride (Betagan) for 16 weeks. Full-thickness filtration surgery was performed with a single 5-minute intraoperative exposure to a sponge soaked with 0.4 mg/mL MMC of one eye in nine rabbits in one group (group A) and to both eyes in 13 rabbits in a second group (group B). In addition, one eye of each rabbit in group B received a daily drop of 0.4 mg/mL MMC for 13 days after the operation. All of the eyes were then followed for 80 days. The intraoperatively applied MMC enhanced the success rate of the filtration surgery in the group A eyes. However, the eyes that also received postoperative drops of MMC (group B) had longer periods of reduced intraocular pressure (IOP) (P [chi-squared = 5.94] < .025), fewer bleb failures (P [chi-squared = 8.09] < .005), and more complications than the eyes that received only intraoperative MMC.
