Are there patients with late-onset schizophrenia in state hospitals?

Diagnoses of all individuals admitted between 1989 and 1991 to a State of Illinois Hospital were examined to determine the prevalence of patients meeting DSM-III-R criteria for late-onset schizophrenia. Four prevalence rates were determined for each year based on the frequency of late-onset patients in (1) total psychiatric admissions, (2) total admissions over age 45, (3) admissions with diagnoses of schizophrenia, and (4) admissions over age 45 and diagnosed schizophrenia. Results showed that the mean (across the three years) of the four prevalence rates of late-onset schizophrenia ranged from 0.24% to 4.1%. This range is far below prevalence rates on hospitalized patients previously reported in the literature (6 to 34%). Reasons for discrepancy are discussed.

Efficacy of anomalous pancreatic drainage in choledochal cysts correlates with age of presentation and suggests etiology.

The etiology and pathogenesis of choledochal cysts, although frequently debated, are as yet unknown. Findings in three recent patients suggest a possible etiology that may also explain the variability in age at presentation. Each of these patients (ages 12 months, four years, and ten years) was found to have an Alonso-Lej Type I cyst and at operation had an absence of the distal intraduodenal common bile duct, suggesting the lack of a common channel with the main pancreatic duct. Partial decompression of the anatomically obstructed bile duct was afforded by an anomalously high insertion of the accessory pancreatic duct and communication with the duodenum by way of the main pancreatic duct. All patients were managed by excision and retrocolic choledochojejunostomy. The efficacy of decompression correlated with the age of presentation and size of the cyst. These findings suggest agenesis-atresia of the distal common bile duct as one possible etiology of choledochal cysts and may explain the variable age at presentation.

A system for slit-lamp polaroid photography.

A system is described in which a SX-70, Alpha Model II, Polaroid, single lens reflex camera, and photoflash unit can be quickly and sturdily mounted to a slit lamp. Such a system can take sharp anterior segment prints of the eye at all slit-lamp magnifications, with white light and in the flourescein mode. The heart of the unit is the modification of an assembly initially designed to attach the camera to a light microscope. The small flash unit and power supply were designed specifically for slit lamp usage. Examples of "instant" photos of the anterior segment at different magnifications are presented.
