<p>BACKGROUNDThe use of Cognitive Behavioural Therapy (CBT) techniques to manage chronic pain is relatively new and understudied in Singapore. Using data collected from group CBT programmes carried out at the Singapore General Hospital (SGH), we seek to explore the efficacy of the programme on pain intensity, self-efficacy, attitudes towards pain, and emotional factors. We also examined the efficacy of the longer 6- to 9-day group programme versus an abridged 2-day version called the Pacing Programme covering only some aspects of the full group programme.p><p>MATERIALS AND METHODSTwenty-nine adult patients underwent the intensive 6- to 9-day group programme while another 10 patients underwent the abridged 2-day group programme. The more extensive group programme encompassed teaching patients cognitive-behavioural methods of coping with pain, such as setting goals, pacing, cognitive restructuring by thinking in more positively, distraction, problem solving, sleep hygiene, communication skills, ability to cope with changes, and relaxation techniques. The abridged programme focused mainly on developing pacing skills. Patients were required to fill out questionnaires at the beginning of the programme, end of the programme, and at the 1-month and 6-month follow-ups to monitor progress.p><p>RESULTSPreliminary results for the intensive 6- to 9-day group programme indicate decrease in pain and pain distress levels, improvements in management of pain, increased confidence to carry out activities despite pain, increased positive self-statements and decreased negative self-statements, decrease in fear of harm and pathophysiological beliefs, as well as decreases in the levels of depression, anxiety, and stress. The abridged 2-day programme yielded little change in pain and pain distress levels, but a slight increase in confidence to carry out activities despite pain.p><p>CONCLUSIONThese preliminary results provide some evidence supporting the efficacy of CBT techniques in chronic pain management and contribute to the growing body of evidence for the effectiveness of psychological and behavioural techniques in the management of chronic pain.p>

The long agonistic protocol for controlled ovarian hyperstimulation (COH) is effective and used most often, thus is considered the gold standard. Therefore any new regimen has to be compared in its results with those obtained with the long protocol. This report compares the efficacy of GnRH agonist and antagonist in a retrospective study of IVF/ICSI carried out in a tertiary teaching hospital from 2003 to 2006. Only the first COH cycle followed by IVF-ICSI from 200 couples (agonist = 120 and antagonist = 80) were analysed. The end points studied included the number of oocytes recovered, number of mature (MII) oocytes, fertilization, cleavage, morphology based embryo quality, pregnancy rate, quantity and cost of gonadotrophin. The average age of female subjects was 35.1 +/- 4.7 years with 50% being 35 years and above. Major infertility factors were tubal blockage, male factor and endometriosis altogether comprising 68%. GnRH agonist and antagonist cycle parameters were comparable except lesser amount of gonadotrophin was used with lower resultant costs (both p < 0.0005) in antagonistic regime. Antagonist regime produce somewhat more good quality embryos (p = 0.065), an insignificant difference. A clinical pregnancy rate per embryo transfer of 16.3% in agonist and 20.6% in antagonist regime was achieved respectively. In conclusion, GnRH antagonist protocol produced a COH response, embryonic development and pregnancy rates on par to GnRH agonist regime. Moreover GnRH antagonist protocol required a shorter stimulation period plus fewer complications. Hence GnRH antagonist regime provided means for a friendlier, convenient and cost effective protocol for patients.

Introduction: We present a patient with long-standing uncontrolled type 2 diabetes mellitus (T2 DM) who developed sudden onset of choreiform movement, which rapidly resolved after insulin therapy and haloperidol. Case Description: A 53-year-old Filipino male, with T2DM and hypertension for more than 10 years, presented with sudden onset of hyperkinetic, involuntary, non-patterned, continuous movements of the left upper and lower extremities. Investigations revealed severe hyperglycemia without acidemia and ketonuria. Cranial computed tomography scan showed hyperdensity on the right caudate and lentiform nuclei. On cranial magnetic resonance imaging, there was T1- weighted hyperintense and T2 - weighted hypointense signal involving the right putamen, globus pallidus and caudate. Cranial magnetic resonance angiography showed stenosis on the cavernous segment of the right internal carotid artery (ICA), left ICA and middle cerebral artery (MCA) junction, the A1 segment of the left anterior communicating artery and proximal P2 segments of the bilateral posterior cerebral arteries. The patient was managed with a basal-bolus insulin regimen to control the blood glucose and haloperidol to manage the extrapyramidal symptoms. Consequently, there was complete resolution of the involuntary movements. Conclusion This case illustrates the importance of a systematic approach to movement disorders and early recognition of this rare diabetes complication known as chorea hyperglycemia basal ganglia syndrome or diabetic striatopathy.

<p>INTRODUCTIONFunctional magnetic resonance imaging (fMRI) is a neuroradiological technique for the localisation of cortical function. FMRI made its debut in cognitive neuroscience and then eventually to other clinical applications. We report our experience with pre-surgical fMRI on a high field scanner, based purely on a clinical platform.p><p>MATERIALS AND METHODSThe protocols included motor, auditory, visual and language fMRI. The choice of protocols was dependant on clinical request and lesion locale.p><p>RESULTSRetrospective analysis and audit of the fi rst 30 consecutive patients over a 12-month period revealed that about 85% of patients had a successful examination. In a pictorial essay, we demonstrate that patients with weakness in performing a motor task showed abnormal activations of the pre-motor and supplementary motor areas.p><p>CONCLUSIONFMRI data greatly enhances the pre-surgical planning process and the conduct of surgery when it is incorporated into the surgical navigation system in the operating theatre.p>

The Singapore public healthcare system has increasingly used the term "right-siting" to describe the principle that stable chronic disease patients should be managed in primary care rather than specialist settings. The majority of primary healthcare providers in Singapore are general practitioners (GPs). The aims of this paper were to measure the quality of diabetes care in specialist and GP settings, and assess right-siting efforts in a tertiary centre in Singapore. Three hundred eighty-three consecutive patients with type 2 diabetes referred to the Singapore General Hospital Diabetes Centre (SGH DBC) between January and March 2005 were analysed. At the first visit, 51 patients (13.3%) were classified as inappropriate referrals and discharged back to the referral source or to primary care. After 12 months, 136 patients (group A = 35.5%) remained on follow-up at SGH DBC. In these patients, significant improvements were seen in mean HbA1c but not blood pressure (BP) or low density lipoprotein-cholesterol (LDL-C). One hundred twenty-eight (group B = 33.4%) patients were discharged from DBC within the 12 months of the study period. Mean follow-up duration in group B was 5.5 months and HbA1c, blood pressure and LDL-cholesterol had improved significantly in these patients. Glycaemic control of group B patients at the time of discharge was significantly better than group A at 12 months (mean HbA1c = 7.15% vs 8.16%; P <0.001). More than half (55.6%) of group B patients achieved HbA1c targets compared to 32.4% from group A (P <0.001). Although mean BP and LDL-C levels fell in group B patients, the percentage of patients achieving BP and LDL-C targets did not improve significantly in both groups. From August 2005 to January 2008, GPs participating in SingHealth's Delivering on Target (DOT) programme enrolled 579 patients under their care for additional diabetic counselling by community nurse educators. Pre- and post-programme HbA1c results were submitted for 370 patients (64%). Mean HbA1c levels of these patients decreased from 8.23% to 7.32% (P <0.001). The proportion of patients who achieved HbA1c <7% increased from 26% to 51% (P <0.01). However, BP and LDL-C levels did not improve. It is difficult to base referral or discharge decisions solely on these indicators. Our studies show that both in the specialist and GP settings, significant improvements in HbA1c are seen. Results for BP and LDL-C, however, showed little improvement. Some degree of rightsiting was seen at SGH DBC with discharged patients showing greater improvements than patients who were retained. However, >30% of patients remained in SGH DBC despite achieving HbA1C targets. Our results indicate the need for better strategies to address the underlying obstacles to right-siting. Of greater concern, the lack of improvement in BP and LDL-C indicates a high degree of clinical inertia to these issues among specialists and GPs treating diabetes in Singapore.

<p>INTRODUCTIONAntibiotic resistance in gram-negative bacilli is an area of increasing importance. This prospective study was performed to survey antibiotic resistance in Escherichia coli (E. coli), Klebsiella spp., Pseudomonas aeruginosa and Acinetobacter spp. over a 1-year period.p><p>MATERIALS AND METHODSNon-duplicate isolates of E. coli, Klebsiella spp., P. aeruginosa and Acinetobacter spp. were collected from participating Singapore hospitals during defined collection periods in 2006 and 2007. Confirmatory identification and antibiotic susceptibility testing were performed at Changi General Hospital. Minimum inhibitory concentrations (MIC) to a defined panel of antibiotics were determined using microbroth dilution methods. The presence of extended-spectrum beta lactamases and AmpC beta-lactamases in Enterobacteriaceae was determined by phenotypic methods, and susceptibility results were defined using current breakpoints from the Clinical Laboratory Standards Institute (CLSI).p><p>RESULTSSeven hundred and forty-six gram-negative bacilli were received for testing. Resistance to extended-spectrum cephalosporins was present in a third of Enterobacteriaceae isolates, and extended-spectrum beta-lactamases (ESBL) carriage was present in 19.6% and 30.1% of E. coli and Klebsiella pneumoniae, respectively. AmpC enzymes were also detected in 8.5% and 5.6% of E. coli and K. pneumoniae isolates respectively. All Enterobacteriaceae were susceptible to imipenem and meropenem. The most active antibiotics against P. aeruginosa were amikacin, meropenem and piperacillin-tazobactam. A third of P. aeruginosa showed reduced susceptibility to polymyxin B. Carbapenem resistance was significantly higher in Acinetobacter baumannii (70.5%) than in other Acinetobacter species (25.0%). The most active antibiotic against A. baumannii was polymyxin B.p><p>CONCLUSIONAntibiotic resistance is prevalent in gram-negative bacilli isolated from Singapore hospitals. The MIC testing surveillance programme complemented susceptibility data from wider laboratory-based surveillance, and has revealed emerging mechanisms of antibiotic resistance.p>

<p>INTRODUCTIONElectrocardiographic (ECG) criteria for left ventricular hypertrophy (LVH), such as the Cornell and Sokolow-Lyon voltage criteria were derived from Western populations. However, their utility and accuracy for diagnosing echocardiographic LVH in Asian populations is unclear. The objective of this study was to assess the accuracy of ECG criteria for LVH in Asians and to determine if alternative gender-specific ECG cut-offs may improve its diagnostic accuracy.p><p>MATERIALS AND METHODSECG and echocardiographic assessments were performed on 668 community-dwelling Asian adults (50.9% women; 57 ± 10 years) in Singapore. The accuracy of ECG voltage criteria was compared to echocardiographic LVH criteria based on the American Society of Echocardiography guidelines, and Asian ethnicity and gender-specific partition values.p><p>RESULTSEchocardiographic LVH was present in 93 (13.6%) adults. Cornell criteria had low sensitivity (5.5%) and high specificity (98.9%) for diagnosing LVH. Modified gender specific cut-offs (18 mm in women, 22 mm in men) improved sensitivity (8.8% to 17.5%, 0% to 14.7%, respectively) whilst preserving specificity (98.2% to 94.2%, 100% to 95.8%). Similarly, Sokolow-Lyon criteria had poor sensitivity (7.7%) and high specificity (96.1%) for diagnosing LVH. Lowering the cut-off value from 35 mm to 31 mm improved the sensitivity in women from 3.5% to 14% while preserving specificity at 94.2%. A cut-off of 36 mm was optimal in men (sensitivity of 14.7%, specificity of 95.5%).p><p>CONCLUSIONCurrent ECG criteria for LVH derived in Western cohorts have limited sensitivity in Asian populations. Our data suggests that ethnicity- and gender-specific ECG criteria may be needed.p>

<p>INTRODUCTIONThe use of adjuvant temozolomide (TMZ) in patients managed with surgery and adjuvant radiation therapy (RT) for glioblastoma multiforme (GBM) has been demonstrated to improve median and 2-year survival in a recent large international multicentre study. To confirm this result in routine clinical practice, an audit of the management and outcome of patients with GBM at The Cancer Institute Radiation Oncology was performed.p><p>MATERIALS AND METHODSAll patients with GBM managed radically at The Cancer Institute Radiation Oncology from May 2002 to 2006 were entered into a prospective database. Patient, tumour and treatment factors were analysed for association with the outcome of median survival (MS). Survival was calculated using the Kaplan-Meier technique and correlation was assessed using Cox proportional hazards regression.p><p>RESULTSForty-one patients with GBM were managed with radical intent over the 4- year period. The median age was 54 years and 66% were Eastern Cooperative Oncology Group (ECOG) 0-1 performance status. Macroscopic, subtotal and biopsy alone procedures were performed in 61%, 29% and 10% of patients, respectively. The median time from surgery to RT was 26 days. Adjuvant TMZ was used in 44% of patients (n = 18). The MS of the total group was 13.6 months, with a 24% 2-year overall survival. The use of TMZ was associated with improved MS (19.6 versus 12.8 months; P = 0.035) and improved 2-year survival (43% versus 0%). A requirement of dexamethasone dose greater than 4 mg at the end of RT (P = 0.012) was associated with worse survival, but there was no association of MS with age, ECOG, tumour size or extent of surgery.p><p>CONCLUSIONThe median and 2-year survival outcomes are comparable to the results of the European Multicentre Study and justify the continued use of TMZ in routine clinical practice.p>

<p>INTRODUCTIONThis study aims to determine the association of geriatric syndromes and depressed mood among respondents with diabetes in a lower income community; and their association with self-management, lifestyle behaviour, and healthcare utilisation. This paper focuses primarily on the 114 respondents with diabetes aged 50+ to inform policy formulation at the community level.p><p>MATERIALS AND METHODSA pilot community health assessment was conducted in 4 blocks of 1- and 2-room apartments in Toa Payoh district from July to November 2009. Using a standard questionnaire, interviewers conducted face-to-face interviews with household members on chronic diseases, geriatric syndromes and health-related behaviour. Data were analysed using SPSSv15.p><p>RESULTSA total of 795 respondents were assessed with a response rate of 61.8%. Of 515 (64.8%) aged 50+ analysed in this study, 22.1% reported having diabetes, of whom 31.6% reported being depressed. Respondents with diabetes who reported being depressed had a higher prevalence of geriatric syndromes compared with those non-depressed; i.e. functional decline (30.6% vs 5.1%, P <0.001); falls (33.3% vs 10.3%, P = 0.003); stumbling (30.6% vs 10.3%, P = 0.007); urinary incontinence (33.3% vs 5.1%, P <0.001), progressive forgetfulness (27.8% vs 6.4%, P = 0.002) and poor eyesight (22.2% vs 6.4%, P = 0.014). They were less likely to comply with medications (86.1% vs 97.3%, P = 0.026) and performed exercise (13.9% vs 53.8%, P <0.001). More had hospital admissions (13.9% vs 7.7%); and they had more outpatient visits per person (2.4 visits vs 0.9 visits, P = 0.03) at Specialist Outpatient Clinics.p><p>CONCLUSIONGeriatric syndromes were associated with the presence of depressed mood among persons with diabetes in the lower income group. As those with depressed mood had more unfavourable self-management and lifestyle behaviour, and utilise higher healthcare services, diabetes management must take these findings into consideration.p>
