Splenic necrosis in Wegener's granulomatosis

The CT appearance of asymptomatic splenic necrosis in a 11-year-old girl with Wegener's granulomatosis is presented. Sonography showed splenic inhomogeneity with patency of the splenic artery and vein. Follow-up CT showed lobulation and shrinkage of the spleen with return to a normal attenuation.     

Wegener's granulomatosis in childhood

The authors reviewed the medical histories and radiological examinations of five pediatric patients with a histologic diagnosis of Wegener's granulomatosis (WG) seen over a six year period in whom a total of 22 thoracic CT scans were performed. Involvement of both the upper and lower respiratory tracts was seen in all patients at presentation. One patient had subglottic stenosis necessitating tracheotomy. Pulmonary hemorrhage occurred in three patients at initial diagnosis. Classic cavitary lung nodules were seen in two patients — one at initial presentation, the other at relapse. The plain radiographic lower respiratory tract manifestations of pediatric WG were protean both at initial presentation and during follow up. Similarly, disease expression was highly variable on thoracic CT examinations but, overall, multifocal parenchymal infiltrates with or without small peripheral nodules were the commonest thoracic CT manifestations. As a consequence of cytotoxic and corticosteroid therapy the long-term prognosis of WG has improved considerably in recent years. Knowledge of the varied patterns of the primary disease and potential for iatrogenic complications are necessary for successful radiologic assessment of pediatric patients with WG.     

Lack of specificity of Chlamydiazyme for detection of vaginal chlamydial infection in prepubertal girls

A 1-year prospective study was undertaken of 65 prepubertal girls referred for evaluation of sexual abuse or vulvovaginitis to compare Chlamydiazyme, an enzyme immunoassay (EIA), with culture for the detection of Chlamydia trachomatis i in vaginal specimens. Five (8%) of 65 patients were initially EIA-positive. On repeat sampling without intervening antibiotic treatment, 4 girls who were initially positive became negative and 1 remained persistently positive. Chlamydial cultures were negative in all patients. The patient with the persistently positive EIA also had Group A streptococcal vaginitis. We were able to demonstrate that some strains of Group A Streptococcus can cause a positive reaction with the EIA. Cross-reactions with other bacterial species are also known to occur. We therefore conclude that Chlamydiazyme is not specific for the detection of chlamydial infection in the vagina of prepubertal girls and, for medicolegal reasons, should not be used for evaluation of sexual abuse.     

Lower limb compartment syndrome complicating pelvic pouch surgery

A 10-year-old boy who underwent prolonged pelvic surgery in the Lloyd-Davies position developed a postoperative lower limb compartment syndrome that was successfully treated by urgent fasciotomy. The clinical and aetiological aspects of this increasingly reported complication must be recognised if serious sequelae are to be avoided.     

The efficacy of audiotapes in promoting psychological well-being in cancer patients: a randomised, controlled trial.

Open or uncontrolled studies have suggested that providing cancer patients with audiotapes of their clinical interviews can improve information recall and reduce psychological distress. We tested these hypotheses in a ''clinician-blind'', prospective, randomised controlled trial. A total of 117 patients newly referred to a medical oncology clinic who were to be given ''bad news'' had their consultations audiotaped. Blind to the clinician, patients were randomly allocated to receive a copy of the tape to play at home or not (control group). At 6 months follow-up, tape group patients reported positive attitudes to the audiotape and were shown to recall significantly more information about their illness than did controls. Overall improvement in psychological distress at 1 and 6 months follow-up, as measured with the 30-item General Health Questionnaire and the Hospital Anxiety and Depression Scale was no different in the two groups. However, a second-order interaction suggested that poor-prognosis patients were disadvantaged specifically by access to the audiotape, with less improvement in psychological distress at 6 months follow-up than non-tape controls. Patient access to audiotapes of clinical interviews promotes factual retention but does not reliably reduce psychological distress and may be actively unhelpful in some subgroups of patients.     

Transpupillary thermotherapy for retinal capillary hemangioma in von Hippel-Lindau disease

Retinal capillary hemangiomas are a common manifestation of von Hippel-Lindau disease. We report the treatment of a peripapillary retinal capillary hemangioma in the left eye of a 30-year-old woman with this condition, using infrared diode laser transpupillary thermotherapy (TTT). The hemangioma was evaluated before and after treatment by ophthalmoscopy, fundus fluorescein angiography, and Doppler ultrasonography. Infrared diode laser TTT was delivered over 3 sessions during a period of 22 weeks, resulting in an improvement in visual acuity from counting fingers to 6/24 and a marked decrease in exudates surrounding the hemangioma. Doppler ultrasonography demonstrated a decrease in intralesional blood flow from 7 cm per second to less than 3 cm per second, together with a decrease in the size of the lesion. Infrared diode laser TTT provides a useful modality in the treatment of retinal capillary hemangiomas, and may be particularly favorable for peripapillary lesions because of its relatively nondestructive characteristics.     

Clinical symptomatology of posttraumatic stress disorder-diagnosed Australian and United States Vietnam combat veterans: an MMPI-2 comparison

The authors compared MMPI-2 scores of 95 Australian and 96 US Vietnam combat veterans diagnosed with posttraumatic stress disorder (PTSD) from structured PTSD clinical interviews. Groups were strikingly similar on the MMPI-2 clinical and validity scales but were different on two content scales, with higher scores on FRS (fears) and BIZ (bizarre mentation) for the US sample. Employment status was included as a factor, because it too discriminated groups, but it did not interact with the veteran group variable to produce scale differences. The roles of employment status and disability payments are considered in accounting for differences in the psychiatric presentations of the groups. Results suggest that American and Australian Vietnam combat PTSD samples are very similar to each other, with implications for the treatment outcome literature.     

The management of pain following day-case surgery

The object of this study was to assess patients' experience of pain management following day surgery. One hundred and two patients agreed to take part in a telephone survey, 2 and 4 days following day surgery. The majority of patients (73%) were broadly satisfied with the quality of pain management they received, however, there was room for improvement. Despite modern anaesthesia and surgery, 17% of patients surveyed reported having severe pain immediately following day-case surgery. The majority (82%) of patients left the day-case ward in pain and an even higher proportion (88%) had pain at some time between 2 and 4 days postoperatively. Severe levels of pain following discharge from hospital were a concern for 21% of patients. It was reported that day-case staff did not always ask patients whether they were in pain. Communication with patients is vital in the delivery of optimal care. More support and more information are needed to manage patients' pain effectively, whilst in the day-case wards and also following discharge, at home.
