INTRODUCTIONThis prospective study aims to evaluate botulinum toxin type A (BTX-A, Botox ®) as a treatment for idiopathic detrusor overactivity (IDO) for patients with symptoms of overactive bladder (OAB).
MATERIALS AND METHODSNineteen patients with IDO were treated with intradetrusal injection of 200 units of BTX-A under cystoscopic guidance. There were 10 males and 9 females, with a mean age of 60 years (range, 38 to 87). Subjective responses were measured using the International Prostate Symptom Score and quality of life (QOL) score, as well as incontinent episodes, functional capacity and voiding intervals obtained from the voiding diary. They were recorded prior to, and at 6 weeks, 3, 6 and 9 months after BTX-A injections. Urodynamic studies were performed between 6 weeks to 3 months post-treatment.
RESULTSThere was statistically significant improvement in subjective parameters at 3 months post-treatment involving QOL (P = 0.002), incontinence episodes (P = 0.004), functional capacity (P = 0.01) and voiding interval (P <0.001). Reflex volume was significantly increased (P = 0.003), and maximal detrusal pressure (P = 0.001) as well as leak volume (P = 0.013) were significantly decreased during follow-up. Results of a gender-based subgroup analysis reveal that BTX-A may be more efficacious in females. Observed side effects included a patient who needed to perform CISC for about 3 months, a patient who had gross haematuria needed bladder washout and 3 patients who required treatments for urinary tract infection.
CONCLUSIONOverall BTX-A, which is well received by most patients, has become a very important part of the armamentarium for the treatment of IDO.

INTRODUCTIONDeveloping effective exercise programmes for the paediatric population is a strategy for decreasing obesity and is expected to help in eventually limiting obesity-associated long-term health and societal impact. In this study, the effects of a 12-week twice weekly additional exercise training, which comprised a combination of circuit-based resistance training and aerobic exercises, in additional to typical physical education sessions, on aerobic fitness, body composition and serum C-reactive protein (CRP) and lipids were analysed in 13- to 14-year-old obese boys contrasted with a control group.
MATERIALS AND METHODSBoth the exercise group (EG, n = 12) and control group (CG, n = 12) participated in the typical 2 sessions of 40-minute physical education (PE) per week in schools, but only EG participated in additional 2 sessions per week of 45 to 60 minutes per session of exercise training, which comprised a combination of circuit-based resistance training and aerobic exercises maintained at 65% to 85% maximum heart rate (HRmax = 220 - age). Body composition was measured using dual energy X-ray absorptiometry (DEXA). Fasting serum CRP and blood lipids were analysed pre- and postexercise programme. Aerobic fitness was measured by an objective laboratory submaximal exercise test, PWC170 (Predicted Work Capacity at HR 170 bpm).
RESULTSExercise training significantly improved lean muscle mass, body mass index, fitness, resting HR, systolic blood pressure and triglycerides in EG. Serum CRP concentrations were elevated at baseline in both groups, but training did not result in a change in CRP levels. In the CG, body weight increased significantly at the end of the 12-week period.
CONCLUSIONThis study supports the value of an additional exercise training programme, beyond the typical twice weekly physical education classes, to produce physiological benefits in the management of obesity in adolescents, including prevention of weight gain.
