A consumer's guide to commercially available urodynamic equipment

Eight commercially available urodynamic machines from 6 major manufacturers (Aspen Medical, Dantec, Electro-Medical Supplies (EMS), Uro-gyn, Ormed and Wiest) were assessed for accuracy, construction and user-friendliness. There was less than 10% inaccuracy with regard to fill volume, void rate and pressure measurements. The Wiest 6000 plus system was between 11 and 14% inaccurate during voided volume measurement and other systems were less than 10% inaccurate. User-friendliness was assessed during routine cystometry and is mainly dependent on the software supplied with the equipment. The merits and faults of each urodynamic system with regard to performing a urodynamic investigation, running a urodynamic service and data management are compared with an "ideal" urodynamic system.     

A survey of wheelchair seating problems of the institutionalized elderly

This study attempted to define and quantify the need for appropriate seating for elderly nursing home residents. A questionnaire was administered to 200 randomly selected nonambulatory elderly residents living in six Memphis area nursing homes. The study results supported previous findings that many nursing home residents have seating and mobility problems. Of the 139 wheelchair users analyzed, 112 (80%) experienced at least one problem related to discomfort, hindered mobility, or poor posture. Thirty-four percent of the residents had at least one problem considered to be severe. In most cases our respondents' seating and mobility problems could have been solved by the tailored application of presently available technologies.     

RSR13 plus cranial radiation therapy in patients with brain metastases: comparison with the Radiation Therapy Oncology Group Recursive Partitioning Analysis Brain Metastases Database.

PURPOSE: This phase II, open-label, multicenter study assessed the efficacy and safety of the potential radiation enhancer RSR13 plus cranial radiation therapy (RT) in patients with brain metastases. The primary end point was patient survival in comparison with the Radiation Therapy Oncology Group Recursive Partitioning Analysis Brain Metastases Database (RTOG RPA BMD). PATIENTS AND METHODS: Eligibility criteria were age > or = 18 years, Karnofsky performance score > or = 70, and brain metastases with solid tumor histology. Patients received cranial RT, 30 Gy in 10 fractions of 3 Gy each, preceded by RSR13, 50 to 100 mg/kg intravenously over 30 minutes. Univariate and multivariate comparisons of survival and cause of death were made between class II study patients and RTOG BMD patients. RESULTS: Fifty-seven RPA class II patients were enrolled. With a minimum follow-up of 24 months, the median survival time and 1- and 2-year survival rates were 6.4 months, 23%, and 11% for the RSR13-treated patients compared with 4.1 months, 15%, and 3% for the RTOG BMD patients (P =.0174). In an exact-matched case analysis (n = 38), median survival time for RSR13 patients was 7.3 months versus 3.4 months for the RTOG BMD patients (P =.006). There was a 54% reduction in the risk of death for RSR13 patients (P =.0267). RSR13-related adverse events of greater than or equal to grade 3 toxicity that occurred in more than one patient included hypoxia, headache, anemia, fatigue, hypertension, and intracranial hypertension. CONCLUSION: RSR13 plus cranial RT resulted in a significant improvement in survival, as well as a reduction in death due to brain metastases, compared with class II patients in the RTOG BMD.     

Growth of Pakistani children in relation to the 1990 growth standards

This study was designed to compare the growth of Pakistani schoolchildren in the UK with the 1990 UK growth standards. Measurements of height, weight, and sitting height were performed on 785 Pakistani schoolchildren aged 5-14 years with the mean values for each age and sex being plotted on the UK growth standards. The results were expressed as SD scores relative to the 1990 reference data. The mean height for the boys was only 0.2 SD scores below the mean for the new growth standards with the mean height for the girls being 0.4 SD scores below the mean. The mean values for weight and body mass index were 0.3 and 0.5 SD scores less than the mean for boys and girls respectively. This study demonstrates that the growth of Pakistani schoolchildren in the UK is comparable to the 1990 UK growth standards with only minor differences. It is not safe to assume that short stature or low body weight in a Pakistani child is due to his or her ethnic background.
