1.Children with Learning Disabilities in the Paediatric Clinic, Hospital Tuanku Ja'afar Seremban: An Overview
The Medical Journal of Malaysia 2011;66(5):487-490
The aim of the study was to document the prevalence of
learning disability among the children attending the
Paediatric Clinic in Hospital Tuanku Ja’afar Seremban. The
demographic distribution of these patients; the age of
detection of the problem; the associated medical conditions
and types of intervention received by these patients were
documented. Patients who were between the ages of five to
twelve years were included in the study. Learning disability was divided into three categories: speech and articulation problems, academic skills disorder and other categories which included developmental delay. Children with cerebral palsy were excluded from the study. Out of 1320 patients screened, 355 were found to have learning disorders. Majority were Malays, with the male to female ratio of 1.9:1. Most of the patients stayed in Seremban. The learning problem was most commonly detected at the age of 4 years and below. The commonest type of learning disorder was developmental delay, followed by academic skills disorder, speech and academic skills problems and speech disorders. Problems that were detected early were speech problems and developmental delay. Majority of the children had associated medical conditions. Most of the patients received some form of intervention but 11.3% did not attend any intervention program at all. A strategy should be formulated and implemented to help this group of children.

Objective To study the bovine coronary artery endothelial cells(BCAEC)damage induced by cigarette abstracts and further clarify the relationship between smoking and cardiovascular diseases.Methods BCAEC were treated with nicotine, mainstream smoke extract(MSW)and sidestream smoke extract(SSW)which had the normal concentration(1.0?10~(-5),0.8?10~(-5), 0.9?10~(-5)mol/L)of nicotine in smoker.The morphological changes of BCAEC were recorded by microscope digital image system. The quantification of apoptotic BCAEC cells was performed by visualization of nuclei stained with 4,6'-diamidino-2-phenylindole and trypan blue exclusion assay was used to examine the percentage of necrotic BCAEC.The caspase activity assay was employed to discuss the mechanism of BCAEC apoptosis.Results BCAEC exposed to nicotine and MSW appeared the typical morphological alteration of apoptosis and necrotic morphological alteration were observed after BCAWC were treated with SSW. 5.89% and 11.94% apoptotic ceils were found after BCAEC were exposed to nicotine and MSW for 24 hours.The level of BCAEC necrosis after treated with SSW was 62.84%.Caspase-3 activity was induced by nicotine and MSW.Conclusion Cigarette smoke extract can induce the cell death of BCAEC.Nicotine and MSW can induce caspase-3 activity increase.Even in the presence of a non-cytotoxic concentration of nicotine and mainstream smoke solution,protease-induced apoptosis of BCAEC can be significantly increased.Sidestream smoke solution may cause BCAEC necrosis instead of apoptosis.Caspase-3 activation is probably the mechanism of BCAEC apoptosis.

Introduction: Patients with asthma-like symptoms pose a
diagnostic dilemma when physical examination is normal.
The usual practice in Malaysia would be to give empirical
asthma treatment. Bronchial challenge test (BCT) is widely
used in many countries to diagnose asthma objectively but it is not widely available in Malaysia.
Objective: To describe our experience with BCT using
methacholine at Queen Elizabeth Hospital as a supporting
tool in the investigation of patients with asthma-like
symptoms.
Methodology: Review of case notes of patients who
underwent BCT from July 2008 till April 2009. BCT was
performed via dosimeter technique. Results were classified
as high hyper responsiveness if the provocative dose of
methacholine required to achieve 20% fall in FEV1 (PD20) was less than or equal to 0.125 μmol, moderate hyper
responsiveness if PD20 was between 0.125 to 1.99 μmol or
mild hyper responsiveness if PD20 was between 2.00 to 6.6
μmol. PD20 of more than 6.6 μmol constitutes a negative MCT.
Results: 29 patients had BCT during the study period. 19
cases were included in this review. The age ranged from 13
to 70 years old. There were 12 males and 7 females. Duration of symptoms ranged from 2 weeks to 23 years. BCT was positive (mild or moderate hyper responsiveness) in 10 out of 19 patients. No patient had high bronchial hyper
responsiveness.
Conclusions: BCT is a useful adjunctive tool in the
investigation of patients presenting with asthma-like
symptoms. This test obviates empirical asthma treatment.
BCT should be made available in all major hospitals in
Malaysia.

Background:
Diabetes is a risk factor for postoperative complications. Previous meta-analyses have shown that elevated glycated hemoglobin (HbA1c) levels are associated with postoperative complications in various surgical populations. However, this is the first meta-analysis to investigate the association between preoperative HbA1c levels and postoperative complications in patients undergoing elective major abdominal surgery.
Methods:
PRISMA guidelines were adhered to for this study. Six databases were searched up to April 1, 2020. Primary studies investigating the effect of HbA1c levels on postoperative complications after elective major abdominal surgery were included. Risk of bias and quality of evidence assessments were performed. Data were pooled using a random effects model. Meta-regression was performed to evaluate different HbA1c cut-off values.
Results:
Twelve observational studies (25,036 patients) were included. Most studies received a ‘good’ and ‘moderate quality’ score using the NOS and GRADE, respectively. Patients with a high HbA1c had a greater risk of anastomotic leaks (odds ratio [OR]: 2.80, 95% CI [1.63, 4.83], P < 0.001), wound infections (OR: 1.21, 95% CI [1.08, 1.36], P = 0.001), major complications defined as Clavien-Dindo [CD] 3–5 (OR: 2.16, 95% CI [1.54, 3.01], P < 0.001), and overall complications defined as CD 1–5 (OR: 2.12, 95% CI [1.48, 3.04], P < 0.001).
Conclusions
An HbA1c between 6% and 7% is associated with higher risks of anastomotic leaks, wound infections, major complications, and overall postoperative complications. Therefore, guidelines with an HbA1c threshold > 7% may be putting pre-optimized patients at risk. Future randomized controlled trials are needed to explore causation before policy changes are made.

Objective:
To compare the efficacy of repetitive transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation (tDCS) on upper limb function recovery among patients who recently had stroke.
Methods:
Subjects with recent stroke (within 1 month) were randomized to rTMS (n=25) and tDCS (n=26) applied over the non-lesioned hemisphere for three sessions per week, followed by tailored upper limb rehabilitation training for a total of 2 weeks. The primary outcomes were changes in the Motor Assessment Scale (MAS), Fugl-Meyer arm score test, Nine-Hole Peg Test (9HPT), hand grip strength, and modified Barthel Index at weeks 2 and 4. Both therapists responsible for training and assessment were blinded to the intervention allocated.
Results:
There was an improvement in all the motor performance scales among both groups (p<0.001). These improvements persisted at discharge. However, there was no significant difference in any of the assessment scales between the two groups. The rTMS group showed a statistically non-significant greater improvement in MAS, 9HPT, and handgrip strength than the tDCS group.
Conclusion
Both interventions produce a statistically significant improvement in upper limb function. There was no statistically significant difference between the two intervention methods with respect to motor performance. It is suggested that a larger study may help to clarify the superiority of either methods.

The ageing population is posing new challenges to Singapore's healthcare system. The rise of dual income and the decline of extended families, as well as an increase in age-related degenerative disorders due to increased longevity render it difficult for the family to remain the primary social safety net to care for our elderly in their own homes. Consequently, nursing homes may become increasingly relevant for resource and expertise-challenged families to cope with the burden of caring for a frail and dependent elderly. However, as the recent Nightingale Nursing Home elderly mistreatment incident attests, the standards of some have been found wanting. This paper will trace the history of nursing homes in Singapore and the evolution of government policies towards them, discuss the challenges and trade-offs of nursing home regulation, and provide suggestions for better care and governance.

Osteochondral lesions of the talus can present as a late complication of ankle injuries. As the talus is largely covered by articular cartilage, it has a limited ability for repair. Early and accurate diagnosis is important as talar integrity is required for optimal function of the ankle. The common presentation is chronic ankle pain with a history of ankle trauma. Conservative treatment involving a period of casting and non-weight-bearing is recommended for acute, non-displaced osteochondral lesions. Surgical management is recommended for unstable lesions or failed conservative management.
