Care of the abused woman. A hospital's educational program assesses values and beliefs

To answer questions about staff's ability to identify, assess, and support victims of woman abuse, St. Joseph's Hospital, Hamilton, Ontario, Canada, organized a task group that included a cross section of staff and representatives of a local women's shelter. A comprehensive literature review strongly confirmed the need for a program that would provide staff with relevant information about abused women and challenge them to examine their values and beliefs. The task group constructed a questionnaire that included six different scales measuring various aspects of respondents' beliefs and attitudes about woman assault. The educational program for the pilot units included a training video, in-service workshops, a resource training manual, and an assessment tool to assist staff in screening female patients. The survey identified some key areas of concern, including some widely held misconceptions about the causes of abuse. After the educational program, test scores showed significant changes, particularly on scales that measured belief in popular myths and the degree to which respondents held perpetrators responsible for their actions. Overall, the project demonstrated that values and beliefs related to woman assault can be significantly affected by an educational approach that combines information sharing with the opportunity for dialogue and questions.     

Congenital pulmonary atresia with ventricular septal defect: angiographic and surgical correlates

Of 181 patients with severe congenital pulmonary atresia and ventricular septal defect or "type IV truncus" (an obsolete term), all but 11% had true central pulmonary arteries. These arteries were demonstrable by large serial biplane angiograms using multiple selective injections into collateral vessels, frequent photographic subtraction, and occasional pulmonary vein-wedge angiograms. These techniques are extremely important for accurate diagnosis and in planning corrective or palliative surgery, which was done in 77% of patients with pulmonary arteries.     

Monitoring universal precautions: a new assessment tool.

OBJECTIVES: Two pilot studies were conducted to produce efficacy data on an observational tool designed to assess the use of Universal Precautions (UP) in patient care settings. The instrument addresses barrier precautions, hand-washing, handling of sharps, and avoidance of unprotected mouth to mouth resuscitation. DESIGN: The Universal Precautions Assessment Tool was submitted to a panel of 3 experts to establish consensual validity. It was pilot tested by 2 simultaneous observers to establish interrater reliability. SETTING: Pilot Study I was conducted in 3 different units within a 100-bed U.S. Army hospital. Pilot Study II was conducted in the emergency department of a large university-based hospital. PARTICIPANTS: Subjects observed were registered nurses providing acute patient care. RESULTS: Two simultaneous raters calculated UP compliance rates of 76.4% and 78.6%, respectively, for 9 nurses in Pilot Study I, and 62% and 65%, respectively, for 5 nurses in Pilot Study II. The intraclass correlation coefficient for the raters' scores in Pilot Study I was 0.992 with a 95% confidence interval (0.979, 0.997). Consensual validity was established. CONCLUSIONS: The instrument has acceptable interrater reliability under the conditions used. Limitations to use include the possibility of a Hawthorne effect and the fact that assessing proper implementation of UP occasionally relies on a "judgment call" by the observer. With test conditions adjusted to minimize these limitations and with proper consideration of sample size, the tool can be used by researchers and by monitors of hospital quality control to measure UP compliance of caregivers individually or collectively.     

Cyclosporine metabolism by P450IIIA in rat enterocytes--another determinant of oral bioavailability?

Cyclosporine is converted to its major metabolites (M-17, M-1, and M-21) in human liver by enzymes belonging to the P450IIIA subfamily. These enzymes are also present in rat and human enterocytes; however, the possibility that CsA is metabolized in enterocytes has not been previously investigated. We therefore directly compared metabolism of 3H-CsA in microsomes prepared from liver and jejunal enterocytes. M-17, M-1, and M-21 were the major CsA metabolites produced by enterocyte microsomes. This metabolism appeared to be catalyzed by P450IIIA, because pretreatment of rats with the P450IIIA inducer dexamethasone significantly increased the rate of CsA metabolism in enterocyte microsomes and preincubation of enterocyte microsomes with anti-P450IIIA IgG inhibited the production of CsA metabolites by greater than 95%. To determine if enterocyte P450IIIA metabolizes CsA in vivo, rats were pretreated with the P450IIIA inducer dexamethasone, the P450IIIA inhibitor erythromycin, or vehicle alone. At laparotomy, 2 mg/kg of 3H-CsA was injected into a sealed loop of jejunum, and after collection of the mesenteric venous blood draining this segment for 45 min, the production of M-17 and M-1 was measured. In the control group, a mean of 3.9% of the recovered radioactivity was found as M-1 and M-17. In the rats pretreated with dexamethasone, a mean of 8.4% of the radioactivity was found as M-1 and M-17 (P less than 0.05 relative to control) and this decreased to 2.3% in the group pretreated with erythromycin (P = 0.08 relative to control). We conclude that P450IIIA in jejunal enterocytes readily metabolizes CsA. Furthermore, the metabolism of CsA by enterocytes in vivo is substantial and likely contributes to "first pass metabolism" of orally administered CsA. Our observations provide novel hypotheses to explain some important drug interactions and interpatient differences in CsA dosing requirements.     

Methods to improve diagnostic accuracy in a community mental health setting

OBJECTIVE: This study determined the extent to which adding structured procedures improved diagnostic accuracy for outpatients with severe mental illness in a community mental health setting. METHOD: The Structured Clinical Interview for DSM-III-R (SCID) was used to interview 200 psychiatric outpatients. A research nurse reviewed medical records and amended the SCID diagnoses accordingly. A research psychiatrist or psychologist reviewed the diagnostic data and interviewed each patient to verify or further modify the previous findings. Diagnostic outcomes at each step of the procedure were compared to determine whether adding additional data improved diagnostic accuracy. The additional time required for each element of the diagnostic procedure was also assessed. RESULTS: Kappa comparisons of the different diagnostic levels showed that adding additional data significantly improved accuracy. Diagnoses rendered by combining the SCID and review of the medical record were the most accurate, followed by the SCID alone, and then diagnoses made by psychiatrists during routine care. In addition, the SCID alone identified five times as many current and past secondary diagnoses as were documented routinely in patients' charts. CONCLUSIONS: Combining structured interviewing with a review of the medical record appears to produce more accurate primary diagnoses and to identify more secondary diagnoses than routine clinical methods. The patients' knowledge of their diagnoses was limited, suggesting a need for patient education in this setting. Whether use of structured interviewing in routine practice improves patient outcomes deserves further study.     

Gambling behavior of Louisiana students in grades 6 through 12

OBJECTIVES: The prevalence of problem and gambling behavior, the average age of onset of gambling behavior, and the co-occurrence of gambling disorder with substance use were determined in the Louisiana student population grades 6 through 12. METHODS: A stratified randomized sample of 12,066 students in Louisiana schools during the 1996-1997 school year was surveyed about gambling behavior using the South Oaks Gambling Screen--Revised for Adolescents (SOGS-RA). RESULTS: Fourteen percent of the students never gambled, 70.1 percent gambled without problems, 10.1 percent indicated problem gambling in the past year (level 2 according to the SOGS-RA), and 5.8 percent indicated pathological gambling behavior in the past year (level 3). Weekly or more frequent lottery play was reported by 16.5 percent. The average age of onset of gambling behavior was 11.2 years. Fifty-nine percent of the students with problem and pathological gambling behavior reported frequent alcohol and illicit drug use. CONCLUSIONS: A significant minority of Louisiana students in grades 6 through 12-15.9 percent--acknowledged gambling-related symptoms and life problems. The association of problem and pathological gambling with use of alcohol, tobacco, and marijuana provides preliminary support for the inclusion of gambling among other adolescent risk behaviors.     

Nodular lymphoid hyperplasia of the lung: a clinicopathologic study of 14 cases

Nodular lymphoid hyperplasia is a controversial entity in which its existence in the lung has been doubted. The current opinion is that most, if not all, such cases represent extranodal marginal zone B-cell lymphomas masquerading as reactive lesions. We found 14 cases of nodular lymphoid hyperplasia in the files of the Pulmonary Department at the Armed Forces Institute of Pathology from 1974 through 1998. All had clinical histories and hematoxylin-eosin slides. In 12 of 14 with paraffin blocks, we applied immunohistochemical antibodies for CD20, CD3, CD43, CD5, bcl-2, bcl-1, CD45RA, and kappa and lambda immunoglobulin light chains. Molecular genetic analysis was performed on paraffin sections in 10 of 14 by the polymerase chain reaction for rearrangements of the immunoglobulin heavy chain gene and the minor and major break-point regions of the chromosomal translocation t (14;18). There were eight women and six men ranging in age from 19 to 80 years (median, 65 yrs). Most lesions (71%) were incidental findings on routine chest x-rays. Most patients (64%) had a single lesion by chest x-ray whereas the remainder had two to three lesions, except for one patient who had "multiple" lesions. There was associated regional lymphadenopathy in five of 14 cases (36%) which, on biopsy, proved to be reactive follicular hyperplasia. The only treatment was surgical excision. Of the seven patients with follow-up information from 8 months to 6 years (mean, 30 mos), none had clinical recurrence and no patient died of disease. The histology and immunophenotype of the lesions were strikingly similar, including abundant reactive germinal centers, intense interfollicular polyclonal plasmacytosis, and a variable degree of interfollicular fibrosis. No case showed a molecular rearrangement of the immunoglobulin heavy chain gene or the minor or major break-point region of the t (14;18). We conclude that nodular lymphoid hyperplasia of the lung, although rare, does exist and deserves its place in the spectrum of reactive pulmonary lesions that ranges from follicular hyperplasia to diffuse hyperplasia of the bronchus-associated lymphoid tissue (lymphoid interstitial pneumonitis).
