INTRODUCTIONAssertive Community Treatment (ACT) provides community-based treatment to patients with severe and persistent psychiatric illnesses, so that they may continue to live and function in the community as they receive psychiatric care. This study aimed to examine the effects of ACT on the outcome of patients over a 1-year period in an Asian population.

MATERIALS AND METHODSThis naturalistic and retrospective cohort study examined the effects of ACT on 100 patients who had completed 1 year of ACT. Parameters used to measure primary outcome were i) number of admissions (NOA) and ii) total length of stay (LOS) in days. Secondary outcome compared the employment status of patients before and after ACT. Paired sample analyses were performed using SPSS.

RESULTS AND DISCUSSIONThe mean reduction in NOA 1 year post-ACT was 57.1%. The mean reduction in LOS 1 year post-ACT was 61.9%. The median reduction for NOA and LOS were both statistically significant (P <0.01). Thirty-seven patients were employed compared to 6 before the programme, a statistically significant effect on employment (odds ratio 9.69, P <0.01).

CONCLUSIONSACT appears effective in reducing the frequency and duration of admissions for patients in Singapore. The employment status of patients also showed improvement over the course of study.

INTRODUCTIONThe aims of this article were to review the role of surgical resection in the management of high-grade gliomas and to determine whether there is any survival benefit from surgical resection.

METHODSA literature review of the influence of surgical resection on outcome was carried out. Relevant original and review papers were obtained through a PubMed search using the following keywords: glioma, resection, prognosis and outcome.

RESULTSPresently, there is a lack of evidence to support a survival benefit with aggressive glioma resection, but this should not detract patients from undergoing surgery as there are many other clinical benefits of glioma excision. In addition, limiting surgical morbidity through the use of adjuvant techniques such as intraoperative magnetic resonance imaging (MRI), functional MRI and awake craniotomy is becoming increasingly important.

CONCLUSIONSIdeally, a randomised controlled trial would be the best way to resolve the issue of whether (and to what extent) surgical resection leads to improvements in patient outcome and survival, but this would not be ethical. The second best option would be well-controlled retrospective studies with a multivariate analysis of all potential confounding factors.

INTRODUCTIONThis study aims to describe the factors associated with surgical site infection (SSI) in elderly patients who underwent hip hemiarthroplasty following a hip fracture, in a single institution over a nine-year period.

METHODSAll patients who underwent hip hemiarthroplasty between 1 January 2004 and 31 December 2012 in our hospital were included in the present study. The detection of SSI was carried out by a trained, independent infection control nurse using the United States Centers for Disease Control and Prevention criteria. Demographic and clinical data were collected retrospectively. Demographics and clinical factors were analysed for potential associations with SSI.

RESULTSAmong the 1,320 patients who met the study inclusion criteria, a total 57 SSIs were documented, giving an infection rate of 4.3%. Patients who waited for more than one week for surgery had a statistically significantly higher risk of SSI (odds ratio 3.030, 95% confidence interval 1.075-8.545, p = 0.036). The presence of SSI was also significantly associated with increased length of hospital stay (p < 0.001). The two main microorganisms detected were methicillin-resistant Staphylococcus aureus and Pseudomonas aeruginosa, which accounted for 50.9% and 26.3% of the SSIs, respectively.

CONCLUSIONWe concluded that the number of days from admission to surgery is a main risk factor for the development of SSI. Steps should, therefore, be taken to prevent unnecessary delay of surgery in elderly patients requiring hip hemiarthroplasty.

INTRODUCTIONThis study aimed to assess the outcome of percutaneous transluminal angioplasty (PTA) as the primary treatment for transplant renal artery stenosis (TxRAS).

MATERIALS AND METHODSA retrospective review of PTA of TxRAS from April 1999 to December 2008 was performed. Twenty-seven patients (17 males (M):10 females (F)) with the mean age of 49.5 years underwent PTA of TxRAS in the review period. Indications for PTA were suboptimal control of hypertension (n=12), impaired renal function (n=6) and both suboptimal control of hypertension and impaired renal function (n=9). All patients had doppler ultrasound scans prior to their PTA. In addition, 5 of these patients had computed tomography angiography (CTA) and another 7 had magnetic resonance angiography (MRA) evaluation. Mean follow-up period was 57.0 months (range, 7 to 108 months).

RESULTSThe stenotic lesions were located proximal to the anastomosis (n=2), at the anastomosis (n=15), and distal to the anastomosis (n=14). Technical success rate was 96.3%. One case was complicated by extensive dissection during PTA, resulting in subsequent graft failure. The overall clinical success rate was 76.9%. Seven out of 26 patients had restenoses (26.9% of cases). These were detected at a mean of 14.3 months post angioplasty (range, 5 to 38 months). All 7 patients underwent a second PTA successfully. Three of these patients required more than 1 repeat PTA.

CONCLUSIONPTA is safe and effective in the management of symptomatic TxRAS and should be the primary treatment of choice. Close surveillance for restenosis is required and when diagnosed, re-angioplasty can be performed.
