The meaning of higher education for people diagnosed with a mental illness: four students share their experiences.

In this qualitative study, four participants diagnosed with a mental illness were interviewed to explore their experiences while attending a post-secondary school. Each participant described how education helped them to find a sense of purpose in their lives. Education is also described as a means of transition from the patient role to other roles such as student or worker.

Epidemiology and natural history of ligase chain reaction detected chlamydial and gonococcal infections.

Objectives: Ligase chain reaction (LCR) technology has dramatically increased the sensitivity of tests for sexually transmitted infections (STIs). It is unknown whether low copy infections (LCR positive, culture negative) have any clinical consequences. We assessed the clinical significance of untreated low copy Chlamydia trachomatis and Neisseria gonorrhoeae infections in a cohort of sexually active women.

Ability of the digene hybrid capture II test to identify Chlamydia trachomatis and Neisseria gonorrhoeae in cervical specimens.

The Digene Hybrid Capture II (HCII CT/GC) test is a combination test designed to detect Chlamydia trachomatis and Neisseria gonorrhoeae in a single specimen. It is a nucleic acid hybridization test which uses signal amplification to increase sensitivity. We compared its performance to that of culture on cervical specimens from 1,370 women.

Small synthetic ligands of the cholecystokinin-B/gastrin receptor can mimic the function of endogenous peptide hormones.

The gastric cholecystokinin-B/gastrin receptor (CCK-BR) is a key regulator of enterochromaffin-like cell function and proliferation. Over the last decade, a number of small non-peptide CCK-BR "antagonists" have been discovered. Here, we demonstrate that some of these non-peptide ligands in fact possess significant ability to activate the human CCK-BR, and are, therefore, more properly categorized as partial agonists.

Comparison of methods for the detection of treponema pallidum in lesions of early syphilis.

Background: The clinical diagnosis of primary and secondary syphilis can be difficult because of the wide variability of lesions. The available laboratory tests (dark-field microscopy and direct fluorescent antibody) require specialized microscopes and skilled technicians, and serologic tests are insensitive in early infection.

Methods: Dark-field microscopy and monoclonal antibody staining were compared to a new solid-phase enzyme-linked immunosorbent assay (Visuwell test) for detection of T.

Evaluation of a deoxyribonucleic acid probe for the detection of Trichomonas vaginalis in vaginal secretions.

Objective: Our purpose was to compare Affirm VP, a new deoxyribonucleic acid probe test, with standard "wet preparation" microscopic examinations and culture for the identification of Trichomonas vaginalis organisms in vaginal secretions.

Study Design: We examined vaginal samples from 615 women with symptoms or signs of vaginitis for T. vaginalis using the deoxyribonucleic acid probe test, microscopic examination of wet preparations of vaginal secretions, and culture in modified Diamond's medium.

Identification of mycoplasmas in urine from persons infected with human immunodeficiency virus.

Voided urine samples from persons with and without human immunodeficiency virus (HIV) infection were examined for mycoplasmas. Mycoplasma hominis organisms were identified in cultures of urine from 32 (18%) of 180 HIV-positive individuals and from 8 (21%) of 38 HIV-negative individuals. In contrast, glucose-utilizing mycoplasmas were identified in the urine of 30 (17%) of the HIV-positive individuals and in none of those who were HIV-negative.
