Postanal repair: which patients derive most benefit? 总被引:8,自引:0,他引:8
J B Rainey D R Donaldson J P Thomson 《Journal of the Royal College of Surgeons of Edinburgh》1990,35(2):101-105
Forty-two patients (37 women, 5 men; mean age 61 years) with varying degrees of anal sphincter dysfunction were treated by postanal repair. Results were analysed in relation to age, sex, presenting complaint and the results of preoperative anorectal physiological tests. Complete continence was restored in 13 (31%), while acceptable but slightly impaired control was achieved in a further 17 (40%). Twelve patients (29%) remained or became totally incontinent. The likelihood of a successful outcome was greater in those presenting with complete incontinence (77% improved) than in those retaining control of solid stool (29% improved, 29% unchanged, 43% worse). Age and sex had no effect on results but pudendal neuropathy, identified in 74% overall, slightly reduced the chance of success. In nine postoperative patients studied, neither the anorectal angle nor anal canal length bore any relation to the results of surgery. 相似文献

Premedical and medical school performance in predicting first-year residency performance 总被引:3,自引:0,他引:3
L K Gunzburger R G Frazier L M Yang M L Rainey T Wronski 《Journal of medical education》1987,62(5):379-384
In the study reported here the authors examined the relationships among 40 measures of undergraduate college and medical school performance and competence in 18 medical care tasks during the first year of residency. A rating form was developed for the study to assess residents' competency in the medical care tasks and was sent to the directors of the residency programs entered by the graduates of a medical school. Stepwise multiple regression procedures were used to analyze the relationship between these ratings of residency performance and the residents' premedical and medical school performance and to identify the best predictors of residency performance for the 1982 and 1984 classes. A Rasch model analysis of the residency performance ratings indicated the ease or difficulty of each of the 18 tasks. The results provide information that would allow medical educators to use premedical and medical school performance to predict residents' competencies. The task of "clinically evaluates research and clinical data" was the most difficult for the graduates; that is, they were rated lower on it than on any other task. Two groups of measures of undergraduate and medical school performance were significantly related to performance in the residency: the Part II examination of the National Board of Medical Examiners (particularly the scores on the obstetrics-gynecology, medicine, surgery, and pediatrics subtests and the overall score) and the clerkships (particularly the third-year medicine clerkship, the fourth-year medicine clerkship, and the surgery clerkship). 相似文献

Relationship of accommodative response and nearpoint phoria in a sample of myopic children. 总被引:2,自引:0,他引:2
Esophoria has been associated with onset and progression of myopia in children. The induction of myopia by optical defocus shown by animal models suggests that a high lag of accommodation during near work may contribute to myopia in children. This paper examines the relationship of nearpoint phoria and accommodative response in a sample of children with myopia. Accommodative response was measured under binocular conditions with the Canon Autoref R-1 autorefractor with a 40 cm viewing distance. Phorias were measured with the von Graefe method using a 40 cm test distance. In the statistical analysis exophoria was scored as a negative number and esophoria was scored as a positive number. The coefficient of correlation of accommodative response with phoria was -0.32 (n = 73; p<0.01), thus showing an association of a more positive (more convergent) near phoria with lower accommodative response. The correlation coefficient increased to -0.39 when an exponential function was used. When only esophores were considered, the correlation coefficient was -0.59 (n = 44; p<0.001). Lower accommodative response (higher lag of accommodation) was associated with greater esophoria. 相似文献

Studies using a variety of investigative methods, including functional brain imaging and electroencephalography (EEG), have suggested that changes in central nervous system (CNS) dopamine function result in altered visual system processing. The discovery of abnormal retinal blue cone, but not red cone, electroretinogram in association with cocaine withdrawal and Parkinson's disease suggests that visual system response to blue light might be a marker for CNS dopamine tone. As there are numerous sex-related differences in central nervous system dopamine function, we predicted that blue and red light stimulation would produce sex-specific patterns of response in primary visual cortex when studied using the blood oxygen level dependent (BOLD) functional magnetic resonance imaging (fMRI) technique. We analyzed the BOLD response to red and blue light in male and female human volunteers (N=20). Red and blue light responses in primary visual cortex (V1) to stepped intensities of red and blue light were compared by sex for threshold to detectable BOLD signal increase and for stimulus intensity vs. BOLD signal response. Near threshold, males and females showed similar BOLD signal change to red light, but males showed a threefold greater increase (0.52%) to blue light stimulation when compared to females (0.14%). Log-linear regression modeling revealed that the slope coefficients for the red light stimulus intensity vs. signal change curve were not significantly different for males and females (z=0.995, P=0.320), whereas the slope coefficients for the blue light stimulus intensity vs. signal change curve were significantly larger in males (z=2.251, P=0.024). These findings support a sex and color-dependent differential pattern of primary visual cortical response to photic stimulation and suggest a method for assessing the influence of specific dopamine agonist/antagonist medications on visual function. 相似文献

A new metabolic pathway for N,N-dimethyltryptamine 总被引:1,自引:0,他引:1
N,N-Dimethyltryptamine (DMT) undergoes a major structural alteration when added to whole human blood or its red blood cells in vitro. A new high-pressure liquid chromatography (HPLC) peak is present in extracts of these treated tissues. The compound responsible for this peak has been identified by ultraviolet spectrophotometry and by mass spectrometry as dimethylkynuramine (DMK). The enzyme responsible for this appears to be different from tryptophan 2,3-dioxygenase and also from indoleamine 2,3-dioxygenase. 相似文献

This study examines factors related to engagement in the services offered by police officer-advocate teams on the basis of police and clinical records for 301 female victims referred to the Domestic Violence Home Visit Intervention (DVHVI) program. The authors find that the severity of intimate partner violence charges and ethnicity of the victim, advocate, and police officer are all significantly related to engagement in the DVHVI, with Hispanic women served by Hispanic advocate-officer teams more engaged in services than African American or Caucasian women. The data suggest that this intervention model may be particularly beneficial for Hispanic victims of intimate partner violence when implemented by a Spanish-speaking officer-advocate team. 相似文献
