This paper outlines some issues facing men who work with children who have been sexually abused. It is argued that there is an intrinsic connection between child sexual abuse and masculine sexuality. Working with abused children faces men with our own potentially abusive tendencies. To some extent commitment to child sexual abuse work can be understood as a response to this situation expressing, for example, reaction formations or reparative urges. Two case examples are given to demonstrate the importance of recognition of these factors and the way such recognition may contribute to therapeutic utilisation of transference and counter-transference emotions. 相似文献

Visual-field areas to a I2e stimulus were measured planimetrically using an X-Y digitizer and a computer program. Sampling of normal subjects and patients suspected of having glaucoma was done at two points in time. Calculations of eye-wall stress were done using ultrasonic data and intra-ocular pressure (IOP) measurements from patient records. For those suspected of having glaucoma who developed chronic open-angle glaucoma (COAG), the time of transition was the second point in time. The visual field area was regressed against patient age at the two points in time. No difference in the regression slopes was found for the normal subjects and unchanged patients. The patients who did develop glaucoma were significantly different. The mean annual rate of visual-field change (rate of decay) was calculated and found to be 28.5 mm2/year for the normals, 153.5 mm2/year for the suspects, and 376.4 mm2/year for those patients who developed glaucoma. The rate of visual-field decay only correlated with patient age (P = 0.03) and eye-wall stress (P < 0.01) in the patients who developed glaucoma. 相似文献

Clinical issues are described in opiate addicts attempting to taper off methadone maintenance, and techniques are suggested to help this patient population. The observations were generated in an experimental “Tapering Network” project, in which opiate addicts on methadone maintenance had the opportunity to receive individual and group counseling, relapse prevention training, self-help groups, and other services. Vignettes illustrate clinical problems with intimacy and social isolation, identity as a former addict, and a “post methadone syndrome” characterized by vulnerability, dramatic swings in mood, and disordered thinking for a period of up to six months after detoxification. To counteract these barriers to recovery, a program model is suggested that uses curricula available in the emerging literature on treatment of substance abuse. These techniques can provide bridges to recovery. 相似文献

Cluster analysis in perimetry is a technique used in the evaluation of localised visual field loss. It has previously been applied to suprathreshold data and, unlike the indices currently available to indicate localised loss, it is influenced by the relative positions of individual defects. This paper describes a cluster analysis for use with data from Program 31 of the Octopus perimeter. To demonstrate the technique, sensitivity values of normal 60-year-old subject were altered to simulate localised loss. Illustrative examples of clinical cases are given, showing differing degrees of localised loss that do not influence the corrected loss variance (CLV) but influence the computed cluster parameters. It is hoped that the value of this form of analysis will be demonstrated in clinical follow-up of glaucoma patients. 相似文献
