INTRODUCTION:
Treatment of pain is an important component of prehospital care. Inhalational analgesia agents have attractive strengths, but there is a paucity of studies comparing these with more conventional agents. We aimed to compare inhalational methoxyflurane and intramuscular (IM) tramadol as first-contact analgesia in the Singapore national ambulance service.
METHODS:
Ambulances were randomised to carry either methoxyflurane or IM tramadol for the first six months and crossed over to the other arm after six months. Patients aged ≥ 16 years, with acute pain arising from musculoskeletal trauma with Numerical Rating Scale (NRS) score ≥ 3 were enrolled. Variables included NRS reduction, time variables, adverse effects, Ramsay Sedation Scores, and patient and paramedic satisfaction scores on a Likert scale.
RESULTS:
A total of 369 patients were enrolled into this study, but 26 patients were excluded due to missing data. The methoxyflurane arm had a shorter median time taken from arrival at the scene to drug administration (9.0 [interquartile range 6.0-14.0] minutes vs. 11.0 [interquartile range 8.0-15.0] minutes). For patients who achieved reduction in NRS ≥ 3 within 20 minutes, those in the methoxyflurane arm took a shorter time. However, the methoxyflurane (46.7%) arm experienced lower proportion of patients not achieving NRS reduction ≥ 3 when compared to the tramadol (71.6%) arm after over 20 minutes. The methoxyflurane arm had significantly higher paramedic and patient satisfaction scores.
CONCLUSION
For the doses of medication used in this implementation study, methoxyflurane was superior in efficacy, speed of onset and administration, but had more minor adverse effects when compared to IM tramadol.

Introduction: This is open label randomised control trial, aimed to identify whether an early (commenced at the time of diagnosis) and intensive nutrition intervention (INI) (individualised dietary counselling, oral nutritional supplements [ONS], telephone, and home visit) can improve weight and dietary intake of gynaecological cancer (GC) patients preoperatively. Methods: Selected GC patients planned for surgery were randomly grouped into control group (CG) (n = 35) and intervention group (IG) (n = 34). Malnutrition screening tool (MST) was used as a screening tool, while Patient-Generated Subjective Global Assessment (PG-SGA) was used as a nutrition assessment tool. IG received an intensive individualised dietary counselling with the supply of ONS at baseline (Day 1). This continued with telephone and home visit follow-up by research dietitian (Day 3 and Day 6). Meanwhile, CG only received general nutritional counselling without supply of ONS. Final assessment was conducted on Day 14. The primary outcomes included weight changes measured using TANITA and dietary intake assessment using 24-hour diet recall. Results: Mean duration of INI was 14 days. At the end of the treatment period, there was a significant weight change between groups (p < 0.001), with 0.14% weight gain in IG and 1.3% weight reduction in CG. Mean energy and protein intake of IG were higher compared to CG by +329 kcal/day and +12.2 g/day, respectively. Conclusion: This study showed that INI that incorporated individualised dietary counselling, ONS, telephone counselling, and home visit can increase energy and protein intake of GC patients, resulting in weight gain.

There is a need to design and develop an affordable motorized vehicle for better mobility among physical disabilities. This study aimed is to initiate appropriate and affordable materials to develop an accessible motorized wheelchair. It includes the feasibility study of the existing used wheelchair, the system used and the characteristic of the physical disabilities symptom. Through the observation, an existing motorized wheelchair uses stainless steel as the main structure, manipulating the shelves heavy-duty accessories, electrical component, heavy-duty battery and car pulley system in which the weight accumulates approximately 100 kg. The heavyweight wheelchair cannot be folded and put inside the car. It also needs to have a special carrier to carry the wheelchair. The field research has also been conducted to evaluate the existing wheelchair system in the market with various systems used, components, and motors material used in the area of technical, usability and comfort before start to redesigning the wheelchair. The results of the study would include the background needs of the characteristic of physical disabilities. The available high-grade aluminium materials will be used to support the mobility and their relevant properties. The design will be done all the way and the specification will be used as an instrument data for the motorized vehicle. The selection of design features, documentation of design procedures and results will be used to create a P.O.C (Prove of Concept) prototype for the meant vehicle. The user will use the preliminary prototyping test and the data (result) will be used to improvise the wheelchair prototype. The second improvised prototype will undergo the second user testing in the area of reliability, stabilization of system, and ease of usage. The results expected will be observed and tested by the user to lead towards the recommendation of the motorized wheelchair design.

Introduction: Hyperhidrosis is a disorder of excessive and
uncontrollable sweating beyond the body’s physiological
needs. It can be categorised into primary or secondary
hyperhidrosis based on its aetiology. Detailed history review
including onset of symptoms, laterality of disease and
family history are crucial which may suggest primary
hyperhidrosis. Secondary causes such as neurological
diseases, endocrine disorders, haematological
malignancies, neuroendocrine tumours and drugs should be
adequately examined and investigated prior to deciding on
further management. The diagnosis of primary
hyperhidrosis should only be made only after excluding
secondary causes. Hyperhidrosis is a troublesome disorder
that often results in social, professional, and psychological
distress in sufferers. It remains, however, a treatment
dilemma among some healthcare providers in this region.
Methods: The medical records and clinical outcomes of 35
patients who underwent endoscopic thoracic
sympathectomy for primary hyperhidrosis from 2008 to 2018
in Department of Cardiothoracic Surgery were reviewed.
Results: The mean age of the patients was 27±10.1years,
with male and female distribution of 18 and 17, respectively.
Fifty-one percent of patients complained of palmar
hyperhidrosis, while 35% of them had concurrent palmaraxillary and 14% had palmar-plantar-axillary hyperhidrosis.
Our data showed that 77% (n=27) of patients were not
investigated for secondary causes of hyperhidrosis, and
they were not counselled on the non-surgical therapies. All
patients underwent single-staged bilateral endoscopic
thoracic sympathectomy. There was resolution of symptoms
in all 35 (100%) patients with palmar hyperhidrosis, 13(76%)
patients with axillary hyperhidrosis and only 2 (50%)
patients with plantar hyperhidrosis. Postoperatively 34.3%
(n=12) of patients reported compensatory hyperhidrosis.
There were no other complications such as pneumothorax,
chylothorax, haemothorax and Horner’s Syndrome.
Conclusion: Clinical evaluation of hyperhidrosis in local
context has not been well described, which may
inadvertently result in the delay of appropriate management,
causing significant social and emotional embarrassment
and impair the quality of life of the subjects. Detailed clinical
assessment and appropriate timely treatment, be it surgical
or non-surgical therapies, are crucial in managing this
uncommon yet distressing disease.

BACKGROUND:
The urinary tract can be affected by both congenital abnormalities as well as acquired disorders, such ascancer, trauma, infection, inflammation, and iatrogenic injuries, all of which may lead to organ damage requiring eventualreconstruction. As a gold standard, gastrointestinal segment is used for urinary bladder reconstruction. However, one majorproblem is that while bladder tissue prevents reabsorption of specific solutes, gastrointestinal tissue actually absorbs them.Therefore, tissue engineering approach had been attempted to provide an alternative tissue graft for urinary bladderreconstruction.
METHODS:
Human adipose-derived stem cells isolated from fat tissues were differentiated into smooth muscle cells andthen seeded onto a triple-layered PLGA sheet to form a bladder construct. Adult athymic rats underwent subtotal urinarybladder resection and were divided into three treatment groups (n = 3): Group 1 (‘‘sham’’) underwent anastomosis of theremaining basal region, Group 2 underwent reconstruction with the cell-free scaffold, and Group 3 underwent reconstructionwith the tissue-engineered bladder construct. Animals were monitored on a daily basis and euthanisation wasperformed whenever a decline in animal health was detected.
RESULTS:
All animals in Groups 1, 2 and 3 survived for at least 7 days and were followed up to a maximum of 12 weekspost-operation. It was found that by Day 14, substantial ingrowth of smooth muscle and urothelial cells had occurred inGroup 2 and 3. In the long-term follow up of group 3 (tissue-engineered bladder construct group), it was found that theurinary bladder wall was completely regenerated and bladder function was fully restored. Urodynamic and radiologicalevaluations of the reconstructed bladder showed a return to normal bladder volume and function.Histological analysisrevealed the presence of three muscular layers and a urothelium similar to that of a normal bladder. Immunohistochemicalstaining using human-specific myocyte markers (myosin heavy chain and smoothelin) confirmed the incorporation of theseeded cells in the newly regenerated muscular layers.
CONCLUSION
Implantation of PLGA construct seeded with smooth muscle cells derived from human adipose stemcells can lead to regeneration of the muscular layers and urothelial ingrowth, leading to formation of a completelyfunctional urinary bladder.

The COVID-19 pandemic resulted in 5 consecutive Movement Control Orders (MCOs) in Malaysia in an attempt to flatten the epidemiological curve, with a reduction of cases. This study aims to use statistical analysis to assess whether the decisive public health interventions in the MCO were efficacious. Three statistical tests were employed: Mann-Kendall trend analysis; one way between groups ANOVA; and Pearson correlation test. Results demonstrated significant differences between the second block, MCO 3-5, compared to MCO 1-2. Johor and Selangor states experienced significant increase in early MCO, whereas Sarawak and Selangor states experienced significant decrease by MCO 3-5. The northern border states of Kedah, Perlis and Kelantan, had caseloads stabilised to zero by MCO 4/MCO 5. This study demonstrates that the MCO was effective within the target of twice the two-week incubation period of COVID-19, with cases from community transmission and importation through the air and southern land borders. Selangor and Sarawak had higher cases in early MCO due to situational factors. In conclusion, MCO has been efficacious, with different states attaining different levels of case reduction due to individualised reasons.

Introduction: Apical Hypertrophic Cardiomyopathy (Apical
HCM) is an uncommon variant of hypertrophic
cardiomyopathy, but it is relatively more common in Asian
countries. This is a retrospective, non-randomised, single
centre study of patients with Apical HCM focusing on their
diastolic dysfunction grading, echocardiographic
parameters and electrocardiograms (ECG).
Methods: All Apical HCM patients coming for clinic visits at
the Institut Jantung Negara from September 2017 to
September 2018 were included. We assessed their
echocardiography images, grade their diastolic function and
reviewed their ECG on presentation.
Results: Fifty patient were included, 82% (n=41) were males
and 18% (n=9) females. The diastolic function grading of 37
(74%) patients were able to be determined using the updated
2016 American Society of Echocardiography (ASE) diastolic
guidelines. Fifty percent (n=25) had the typical ace-ofspades shape left ventricle (LV) appearance in diastole and
12% (n=6) had apical pouch. All patients had T inversion in
the anterior leads of their ECG, and only 52% (n=26) fulfilled
the ECG left ventricular hypertrophy (LVH) criteria. Majority
of our patients presented with symptoms of chest pain (52%,
n=26) and dyspnoea (42%, n=21).
Conclusion: The updated 2016 ASE guideline makes it easier
to evaluate LV diastolic function in most patients with Apical
HCM. It also helps in elucidating the aetiology of dyspnoea,
based on left atrial pressure. Clinicians should have a high
index of suspicion for Apical HCM when faced with deep T
inversion on ECG, in addition to a thick LV apex with an aceof-spades appearance during diastole.
9.The Chromosomal DNA Damage in Buccal Mucosa Cells among Schools Children in The Vicinity Of Mobile Base Stations in Selangor
Malaysian Journal of Medicine and Health Sciences 2019;15(SP4):124-129
Abstract
Introduction: The increased use of mobile phones has increased the mobile base stations (MBS) deployment. While understanding of radiation protection is growing among the public, questions regarding early-life exposure to radiofrequency radiation (RFR) from MBS in children are of importance as to whether it will raise the chances of developing chronic diseases during adulthood. Taking into account the sitting location of MBS, the purpose of this study is to evaluate the chromosomal DNA damage in buccal mucosal cells between school children exposed to RFR emitted from base station antennas. Method: This is a comparative cross-sectional study in which two group of school children were sampled i.e. exposed groups are children whose school located near MBS (≤200 meters); unexposed groups are children whose school located distant far from the MBS (>200 meters). Digital RF Analyzer was used to measure RFR at the school surrounding. Buccal mucosa cells from the oral cavity were sampled to examine the level of micronuclei (MN) frequencies. Results: This study found that the densities of the RFR energy differed in range. Although all measurements showed the RFR reading below the acceptable exposure level, there were still significant variations at each location assessed. Statistically, the MN frequency is significantly different when compared to the exposed and non-exposed group. Conclusion: To understand the mechanism of health effects from exposure to low-level RFR emited from MBS, further study should consider environmental factors influencing MBS sitting on RFR emission, as well as examining the health effects into molecular levels.

INTRODUCTION:
Lactogenesis II (LaII) failure can be prevented in at-risk mothers with simple proactive interventions. In a randomised trial, we investigated the efficacy of early and regular breast milk expression in establishing LaII, using an electric double-breast pump.
METHODS:
Mothers with uncomplicated singleton deliveries were randomised to intervention (n = 31) or control (n = 29) groups. The former commenced breast milk expression with an electric pump within one hour of delivery and maintained regular expression with direct breastfeeding. Control mothers directly breastfed without regular pump expression. Expressed milk volumes were analysed for citrate, lactose, sodium and protein.
RESULTS:
Median time of LaII was Day 3 (interquartile range [IQR] 1 day) with intervention and on Day 4 (IQR 1 day) among controls (p = 0.03). Biochemical steady-state concentrations were achieved around early Day 4 (sodium, total protein) and Days 4-5 (citrate, lactose). Sodium, protein and lactose levels were similar in both groups over seven days, at 5.80 mM, 0.68 mM and -13.38 mM, respectively. Mean daily milk volume with intervention was 73.9 mL on Day 3 and 225.2 mL on Day 7, greater than controls (25.4 mL on Day 3 and 69.2 mL on Day 7; p < 0.2). Mean infant weights were similar on Day 8 at 3,477 g with intervention and 3,479 g among controls.
CONCLUSION
LaII is established by postnatal Day 3 with early initiation of regular breast milk expression, a useful intervention for mothers at risk of early-onset breastfeeding failure.
