The study on biodiversity of forensically important Diptera in the tropical rain
forest in Malaysia is scarce. Thus, a preliminary survey was conducted at a jungle fringe near
Kampung Bahagia Bukit Lagong, Sungai Buloh, Selangor. A rat carcass was offered to attract
carrion flies and we collected an adult female calliphorid, Hypopygiopsis fumipennis (Walker,
1856) during the fresh stage of carcass decomposition. The female fly was allowed to oviposit
on chicken liver in a container and the resulting larvae were reared to the adult stage. Along
the developmental process, several individuals from each instar were collected and preserved
in 70% ethanol and then processed on the slides. We recorded the duration of development for
each instar and described its larval features for the first time. The third instar larvae of H.
fumipennis showed accessory oral sclerite present, anterior spiracle with 13-15 papillae,
intersegmental spines mostly unicuspid with pointed end, and posterior spiracles heavily
sclerotized with inter-slit projections. Some larval differences between H. fumipennis and
Hypopygiopsis violacea were noted.
2.Light microscopy and molecular identification of Sarcocystis spp. in meat producing animals in Selangor, Malaysia
Tropical Biomedicine 2015;32(3):444-452
One thousand and forty-five tissue samples of skeletal muscles, tongue, heart,
diaphragm and esophagus were collected from 209 animals (43 sheep, 89 goats and 77 cattle)
from an abattoir in Selangor between February and October, 2013. Each sample was divided
into three pieces with each piece measuring 2-3 mm3. Each piece was then squeezed between
two glass slides and examined microscopically at x 10 magnification for the presence of
sarcocystosis. Three positive samples from each animal species were then fixed in 10%
formalin for histological processing. Seven positive samples collected from each animal
species were preserved at -80°C or 90% ethanol for gene expression studies. Microsarcocysts
were detected in 114 (54.5%) animals by light microscopy (LM). The infection rates in sheep,
goat and cattle were 86, 61.8 and 28.6% respectively. The highest rate of infection was in the
skeletal muscles of sheep (64.9%) and goats (63.6%) and in the heart of cattle (63.6%). The
cysts were spindle to oval in shape and two stages were recognized, the peripheral metrocytes
and centrally located banana-shaped bradyzoites. 18S rRNA gene expression studies confirmed
the isolates from the sheep as S. ovicanis, goats as S. capracanis and cattle as S. bovicanis.
This, to the best of our knowledge, is the first molecular identification of an isolate of S.
ovicanis and S. capracanis in Malaysia. Further studies with electron microscopy (EM) are
required in the future to compare the features of different types of Sarcocysts spp.

Osteomyelitis refers to an infection of the bone characterized by progressive inflammatory destruction caused by infecting microorganism. Open fracture carries the risk of developing osteomyelitis from 3 to 50% with a high amputation rate. Salvage of the limb is always a challenge and needs perseverance. We report the case of a 44-year-old male with chronic osteomyelitis with successful multiple limb salvage surgeries. The curative approach to chronic osteomyelitis has the following goals including arrest of infection, pain reduction and salvage of limb and function. With regard to survival and function, the result obtained in this case is more promising compared to above knee amputation.

Theincidence of envenoming from king cobra, Ophiophagus hannah in human is relatively rare. Its venom acts on the postsynaptic region of the neuromuscular junction causing descending flaccid paralysis. Locked-in syndrome is a clinical state of inability to provide motor response in a conscious patient. Many reported cases of locked-in syndrome following neurotoxic snake-bite mimics brain death. We report a case of a middle aged man who presented with progressive neurological deficit following a king cobra bite over his right arm. He had local and systemic neurotoxic envenoming. His condition deteriorated, and was intubated and ventilated in the emergency department. He received a total of 33 vials of the Ophiophagus hannah monospecific antivenom and subsequently recovered well with no neurological deficit. Retrospectively, he was able to recall the events and while he was lying paralysed and intubated under minimal sedation in the intensive care unit. He described it as a terrifying and painful experience. This case highlights the rare presentation of locked-in syndrome following a systemic envenoming from a king cobra bite. It is important to differentiate neurotoxic snake envenoming lock-in syndrome from brain dead. Patients are unable to respond to physical pain and require adequate analgesia. A patient suffering this highly distressing experience may require psychological support.

Hyperbaric oxygen therapy (HBOT) was established to increase oxygenation and antimicrobial effect that potentially improve the healing of chronic ulcer. Present study aim to assess the effects of HBOT in chronic diabetic foot ulcer (DFU). A total of sixty patients classified according to Wagner 1, 2 or 3 chronic diabetic foot ulcers, were recruited and subsequently divided randomly into two groups; HBOT and control group. All patients underwent the standard treatment for DFU, but for the HBOT group, underwent 20 HBOT sessions, each lasted 80 – 90 mins at 2.5 atmospheres absolute (ATA). White cell count (WCC) and C-reactive protein (CRP) levels were taken during inclusion, at second and fourth week of treatment. Wound sizes were documented at each follow up until six months follow up. SF-36 at one-month post hyperbaric oxygen therapy was used to measure the health-related quality of life. Reduction of WCC and CRP in HBOT group were significant throughout the treatment (p=0.046 and p=0.039, respectively). A total of 26 patients (86.7%) from the HBOT group achieved complete ulcer healing at six months’ follow-up, while 18 patients (60%) in the control group’s ulcer healed completely. Patients treated with HBOT had significantly better mental and physical health constituent of quality of life. It must be emphasised that HBOT is an adjunctive therapy to the standard management of chronic DFU in accelerating wound healing for a better quality of life.
6.END-TO-SIDE NERVE TRANSFER IN NEUROPATHIC PAIN POST BRACHIAL PLEXUS INJURY
Journal of University of Malaya Medical Centre 2018;21(2):71-73
We report a case of a 59-year-old gentleman with complete left brachial plexus injury. He presented with chronic pain over the dorsum of his left hand since the injury eight years ago. Medical treatment had been optimized but the pain still persists. End-to-side nerve transfer was done involving superficial sensory radial nerve and median nerve to alleviate the pain. The surgery was considered successful as the patient claimed that the pain score had reduced a few weeks postoperatively. However, there was no sensory recovery and functionally no improvement was observed

Post-surgical orbital defects pose a severe effect on patient, psychologically and physically, especially in the eventual
return to the society and daily routine. In cases where reconstructive surgery is not possible, prosthetic rehabilitation
is crucial in addressing this issue. Implant-supported orbital prosthesis provides superior retention, however, it is not
economically acceptable for some cases. Various modes of retention are available to cater to each patient’s diagnosis, treatment need and economical status. This article describes the procedures in the construction of a customized
silicone orbital prosthesis using adhesive and spectacles for retention. This technique is cost-effective and simple
while providing comfort and satisfaction for the patient.

The rarity of acute psychosis in typhoid fever can result in delayed and misdiagnosis of the condition. We report a case of a 20-year-old man who presented with fever and acute psychotic symptoms. This was associated with headache, dizziness, and body weakness. There were no other significant symptoms. Neurological examination revealed reduced muscle tone of bilateral lower limbs but otherwise unremarkable. The computed tomography (CT) scan of his brain showed no abnormality. Blood specimens for microbiological culture grew Salmonella Typhi. This isolate was susceptible to chloramphenicol, ampicillin, ceftriaxone, ciprofloxacin, and trimethoprim-sulfamethoxazole. He was treated with intravenous ceftriaxone for one week and responded well. He was discharged with oral ciprofloxacin for another week. The repeated blood and stool for bacterial culture yielded no growth of Salmonella Typhi.

BACKGROUND:
Globally, over four million deaths are attributed to exposure to household air pollution (HAP) annually. Evidence of the association between exposure to HAP and under-five mortality in sub-Saharan Africa (SSA) is insufficient. We assessed the association between exposure to HAP and under-five mortality risk in 14 SSA countries.
METHODS:
We pooled Demographic and Health Survey (DHS) data from 14 SSA countries (N = 164376) collected between 2015 and 2018. We defined exposure to HAP as the use of biomass fuel for cooking in the household. Under-five mortality was defined as deaths before age five. Data were analyzed using mixed effects logistic regression models.
RESULTS:
Of the study population, 73% were exposed to HAP and under-five mortality was observed in 5%. HAP exposure was associated with under-five mortality, adjusted odds ratio (OR) 1.33 (95% confidence interval (CI) [1.03-1.71]). Children from households who cooked inside the home had higher risk of under-five mortality compared to households that cooked in separate buildings [0.85 (0.73-0.98)] or outside [0.75 (0.64-0.87)]. Lower risk of under-five mortality was also observed in breastfed children [0.09 (0.05-0.18)] compared to non-breastfed children.
CONCLUSIONS
HAP exposure may be associated with an increased risk of under-five mortality in sub-Saharan Africa. More carefully designed longitudinal studies are required to contribute to these findings. In addition, awareness campaigns on the effects of HAP exposure and interventions to reduce the use of biomass fuels are required in SSA.

Sarcocystosis, a parasitic infection caused by a protozoa belonging to the genus
Sarcocystis, is found worldwide in both and animals. Sarcocystis spp., require two animal
hosts to complete their life cycle. The infection has gathered more global attention after
recent outbreaks, especially amongst wester travellers to Malaysia. Other than sporadic
cases and the current outbreaks, little information is available regarding human Sarcocystis
infection in Malaysia. The present study aims to determine the prevalence of sarcocystosis
among humans using an immunofluorescent antibody (IFA) test applied to dried blood on
filter papers. A total of 200 blood samples were collected on filter papers from autopsy cases
at two Malaysian hospitals: Sungai Buloh Hospital (peninsular Malaysia) and Queen Elizabeth
Hospital (Malaysian Borneo). Antigens were prepared from bradyzoites harvested from positive
goats’ muscle samples. Of the 200 samples, 32 (16%) had Sarcocystis antibodies that showed
positive fluorescence reactions on filter papers. There was no significant difference (t-test,
p value > 0.05) in prevalence rates between samples collected from autopsies at peninsular
Malaysia and Malaysian Borneo. The results demonstrated that the filter paper technique can
be used as one of the alternative serological tests in the diagnostic of human sarcocystosis.
