MD Concept: a model for integrating medical knowledge.

Many integrated clinical information systems depend on large knowledge bases containing dictionary of terms as well as specific information about each term and the relationships between terms. We propose a knowledge base model called MD Concept which is based on a semantic network and uses an object-oriented paradigm and relational tables. A prototype has been developed which integrates the Unified Medical Language System (UMLS) with other databases including the Systematized Nomenclature of Medicine (SNOMED II), the Diagnostic and Statistical Manual of Mental Disorders (DSM-IIIR) and a pharmaceutical database. We demonstrate how a user can easily navigate in this knowledge world using a browser.

PureMD: a Computerized Patient Record software for direct data entry by physicians using a keyboard-free pen-based portable computer.

This paper describes the data acquisition features of the PureMD Computerized Patient Record (CPR) software designed specifically for physicians. The physician uses a stylus to point, draw and handwrite on a Dynamic Dialog Interface that provides the same flexibility as the paper record and numerous other advantages. The clinical data thus entered is highly organized, easily legible and retrievable in many ways. The underlying Medical Knowledge Base (MKB) was optimized for rapid, intuitive and consistent data entry and automatic coding with minimum handwriting.

Endemic focus of Fasciolopsis buski infection in Bangladesh.

Stool surveys were conducted on children 2--10 years of age in 27 villages within Dacca District and around this index area (1,668 children were sampled), revealing an endemic focus of Fasciolopsis buski infection to the south and the east of Dacca District. In order to determine the seasonal variation in the total snail populations and the natural rate of F. buski infection in the snails, two species of planorbid snails, Segmentina (Trochorbis) trochoideus and Hippeutis (Helicorbis) umbilicalis, were periodically sampled for 12 months from a village endemic for F. buski infection. Gymnocephalous cercariae were found in S. (T.) trochoideus snails during August, September and October. The size of the snail population (n = 1,275) was significantly correlated with inches of rainfall (r = +0.62; P less than 0.05) and water temperature (r = +0.59; P less than 0.05). The natural infection rate of F. buski in the snails ranged from 0.5--2%. Snails from non-endemic areas were exposed to 3--10 miracidia. A total of 13 of 49 (27%) of H. (H.) umbilicalis and 6 of 14 (43%) of S. (T.) trochoideus had gymnocephalous cercariae present 4 to 6 weeks after exposure to miracidia. Thus, snail strain variation is unlikely to be a barrier to F. buski transmission.

Single dose piperazine therapy for Ascaris lumbricoides: an unsuccessful method of promoting growth.

One-hundred eighty-five Bangladeshi children age 1 1/2 to 8 yr with no Ascaris lumbricoides infection or with light, moderate, or heavy infection were randomly assigned to treatment of placebo groups, with treatment given in a double-blind fashion. The groups were comparable for nutritional and socioeconomic parameters. Treatment consisted of a single dose of piperazine citrate administered twice within a 2-wk period. The cure rates for the low, moderate, and heavy A. lumbricoides infected subgroups were 53, 31, and 36%, respectively. With more severe infections, worm eradication was more difficult and the rate of reinfection after treatment was more rapid. The rate of reinfection was significantly different for the low A. lumbricoides infected treatment and placebo subgroups for 5 months after treatment, for the moderate treatment and placebo subgroups for 3 months after treatment, and for the heavy A. lumbricoides infected treatment and placebo subgroups there was a difference, although not significant, for 1 month after treatment. Anthropometric measurements were obtained for a period of 11 months. Analysis of covariance revealed no significant difference for change of weight, change of height, weight-for age, weight-for-height, height-for-age, triceps skinfold, midarm circumference, and the abdominal girth to chest circumference ratio between the treatment and placebo groups after drug administration. The results of this study do not support single dose worm therapy as a means to enhance growth.
