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.

INTRODUCTIONThis study aimed to develop a realistic and lifelike uterine model for the training of hysteroscopy skills.

MATERIALS AND METHODSA lifelike "uterine" model was constructed using female pig bladder. The pig bladder was enclosed within a malleable mould, with both ureters blocked by pins. Both rigid and flexible hysteroscopes were used in this study.

RESULTSBasic diagnostic hysteroscopy can be performed in the usual fashion using this lifelike model. The cost of each learning station is minimal. Pig bladder accurately simulates the human uterus with its realistic tactile feel, and conditions in the surgical environment, including obscuration of vision by debris, uterine "folds", realistic "ostia", incomplete shearing of tissue, "uterine" perforation, etc.

CONCLUSIONThis low-cost novel model provides realistic tissue resistance and yields an almost anatomically accurate hysteroscopic training tool, thereby allowing trainees to effectively acquire both diagnostic and therapeutic hysteroscopic skills.

Aims: The aim of this study was to investigate the genetic relatedness of the most prevalent Candida bloodstream infection (BSI) species in in a Malaysian population via Randomly Amplified Polymorphic DNA-Polymerase Chain Reaction (RAPD-PCR) fingerprinting. Methodology and results: The genomic DNA of 43 Candida BSI blood culture samples obtained from Universiti Malaya Medical Centre (UMMC) was isolated, after which species identification was carried out using PCR with ITS-1 and ITS-4 pan-fungal primers in conjunction with CHROMagar™ Candida. The predominant Candida species in the BSI samples is Candida albicans (14 out of 43 isolates). RAPD-PCR on these 14 C. albicans clinical isolates was performed using PST as the arbitrary primer. Data analysis using MEGA found an overall non-relatedness of these 14 clinical isolates [average similarity coefficient (SAB) value 0.733±0.172]. Following in-depth analysis, five of the 14 isolates were observed to be identical (SAB values of 1.00 each), four isolates had SAB values of 0.80-0.99, indicating that they are highly similar, but are non-identical, while five isolates are unrelated (SAB lower than 0.80). This suggests that microevolution might have occurred and that these clinical isolates may possibly belong to different strains. Conclusion, significance and impact of study: A fair degree of genetic heterogeneity was found among the 14 C. albicans isolates from UMMC. To our knowledge, this is the first report on the genetic profiles of C. albicans bloodstream infection isolates from Malaysia, warranting further studies in the possible evolutionary trends within this Candida species in Malaysia.

Objective To investigate the management and control of hypertension in patients with chronic kidney disease(CKD) and its associated factors.Methods Data of 726in-patients with CKD and hypertension who hospitalized in our hospital from March 2009 to April 2010 were studied.Results 91.74％ of patients was treated with antihypertensive medications,and 21.21％, 22.59％, 19.56％, 28.37％ of patients received 1, 2, 3, ≥4 antihypertensive drugs,respectively.42.4％ of patients with CKD and hypertension could be controlled up to the standard,and the mean blood pressure was(137.86±20.75)/(76.30±11.35) mm Hg.There was significant difference among stage 1 plus 2, 3, 4 plus 5 (non-dialysis), 5 (dialysis) kidney diseases, with the hypertension control rate being 50.8％, 46.7％, 42.0％, 33.5％, respectively.The hypertension control rate of non-dialysis patients was significantly higher than that of dialysis (44.9％ vs 33.5％,P＜0.05).There was no significant difference between blood dialysis group and peritoneal dialysis group(32.3％ vs 38.7％, P＞0.05).Multivariate Logistic regression analysis showed that female (OR=1.787, 95％CI 1.045-3.056)and ACEI application (OR=4.378, 95％CI1.830-10.472) were positively associated with hypertension control.Whereas, diabetes (OR=0.415, 95％CI 0.188-0.919)and pulse pressure (OR =0.847, 95％ CI 0.811-0.885) were associated with inadequate blood pressure control.ConclusionsDespite almost universal hypertension treatment is used in patients with CKD and high blood pressure, the hypertension control rate is still suboptimal.Female and ACEI are positively associated with adequate hypertension control, whereas diabetes and pulse pressure are negatively associated with the standard.

ObjectiveTo investigate the influence of recombinant thioredoxin (TRX)on apoptosis of myocardium cell in viral myocarditis of mice.MethodsTwenty-four Balb/c mice,weighting 12 - 14 g,were randomly divided into 3 groups:the control group,the virus group and the protective group,8 mice in each group.The virus group and the protective group were injected with 0.1 ml 100TCID50 Coxackie virus B3 (CVB3)intraperitoneally,and the control group was injected equal volume of saline.Therewithal the protective group was injected with TRX(2 mg/kg) by tail vein,and the virus group was injected saline the same way.After 14 days all mice were killed and hearts were taken.Changes of myocardial histopathology was observed with optical microscope,cell apoptosis was checked by TUNEL technique,and the expression of apoptosis-related proteins (Bcl-2,caspase-3)in infiltrated cell of myocardium was determined by immunohistochemistry.Results(①)Lymphocyte infiltration and necrosis were observed in survivals of the virus group,sporadic coagulation necrosis and ballooning degeneration of cells were observed in the protective group,however no myocardial lesion was found in the control group.(②)TUNEL technique showed that the positive ratio of apoptosis in the virus group and the protective group[(90.23 ± 3.63)％,(20.02 ± 2.41)％] was significantly higher than that of the control group(0.00 ± 0.00,all P ＜ 0.05),the positive ratio of apoptosis in the protective group was significantly lower than that of the virus group (P ＜ 0.05 ).(③)Immunohistochemistry showed that the expression of protein Bcl-2(+,++,+++) in the virus group and the protective group was significantly higher than that of the control group (all P ＜ 0.05).The expression of protein Bcl-2 in the protective group was significantly higher than that of the virus group(P ＜ 0.05).The expression of caspase-3 (+,++) was significantly higher in the virus group and the protective group than the control group (all P ＜ 0.05).Compared with the virus group,the expression of caspase-3 in the protective group was significantly lower(P ＜ 0.05).ConclusionTRX could inhibit cardiomyocyte apoptosis in viral myocarditis mice and the inhibition is related to regulation of apoptosis-related protein expression.

BACKGROUNDObstructive sleep apnea affects up to 2.9% of children. This study was to determine demographic and clinical characteristics of a group of children with obstructive sleep apnea syndrome (OSAS) as defined by sleep polysomnography (PSG).

METHODSA prospective study was conducted in a public-funded general hospital in Hong Kong of China. Children confirmed to have OSAS by PSG were followed up between January 1997 and December 1998. Tonsillectomy and adenoidectomy (T&A) was offered to those with moderate to severe OSAS, and medication was offered to those with mild OSAS. All children were followed up regularly in the sleep clinic and sleep PSG was repeated for those with marked relapse in symptoms.

RESULTSEighty-nine children (64 boys and 25 girls, mean age 7 years) were confirmed to have OSAS out of 352 children who underwent PSG during the study period. The most common symptoms of OSAS were snoring (100%) and sweating (81%) during sleep and nasal blockage (61%) and sleepiness (34%) during daytime. Severe OSAS occurred in 15 children. Moderate OSAS occurred in 33 children. Forty-one children had mild OSAS. Forty-nine children underwent T&A, 5 (boys, < 5 years) out of whom were found to have recurrent OSAS within 1 year.

CONCLUSIONA male predominance has been found in a group of Hong Kong children with OSAS. Boys undergoing T&A at an early age (< 5 years) will be more likely to develop repeated OSAS.
