Charred human remains were found in the smoking ambers of a dying fire in an oil palm plantation in Selangor, Malaysia in the midnight of January 28, 2013. Investigations showed that palm fronds and rubber tires were used to light and sustain the blaze. At least four to five tires were estimated to be used based on the residual burnt metal wires at the site. The remains were brought to the Department of Forensic Medicine, Hospital Sungai Buloh, Selangor for post-mortem examination. Pre-autopsy imaging showed a fractured skull with presence of a bullet in the head. The body belonged to a male with unrecognizable facial features, pugilistic attitude, and reduced body size caused by fire damage with sparing of the posterior surface. A large fracture was present at the skull vault. An entry gunshot wound was observed on the left side of the body of mandible, which was associated with base of skull fracture. Heat-related fractures were also noted on the right side of the frontal bone. A projectile was retrieved from the right side of the occipital lobe. Further examination showed presence of soot and hyperaemic larynx, trachea, main bronchi, and oesophagus. Black spots measuring 1 to 2 mm were present on the surface and parenchyma of the heart, liver, pancreas and kidneys. Histopathology examination showed black particles within the vessels in the affected organs. We report this rare finding in a charred body and present a discussion based on published literature on this issue.

AIM: To report a rare case of severe contact lens related fungal keratitis due to fusarium sp, which not only was successfully treated with therapeutic penetrating keratoplasty but also aided in the confirmation of diagnosis. METHODS:Case report.RESULTS: A 39-year-old private clerk Malay lady who wore extended wear soft contact lens for the past 18 years, presented with acute right eye pain and redness for 10 days duration. Ocular examination showed multiple round feathery paracentral corneal ulcers with presence of minimal hypopyon. Clinical diagnosis of presumed fungal keratitis was made. She was treated with broad spectrum topical antibiotics and antifungal agents after repeated corneal scrapping was negative either for fungi or for the bacteria. However, she developed deterioration of the right eye keratitis. Other topical and systemic antifungal agents were instituted. Unfortunately the right corneal ulcer became further deteriorating. Finally a therapeutic penetrating keratoplasty has done in order to preserve the globe and limit the infection after one and a half months of presentation. The diagnosis and the etiology agent were only confirmed based on histopathological examina-tion and polymerase chain reaction (PCR) from corneal button revealed fusarium sp.CONCLUSION:This case highlights the rare case of fusarium sp as an etiology of severe contact lens related fungal keratitis. This case also illustrates the challenge in managing fungal keratitis. Therapeutic penetrating keratoplasty is the ultimate choice in controlling further infection and perserving the globe.

Most previous studies on RET and p53 proteins have focused on thyroid papillary carcinoma. We investigated the role of RET and p53 protein expressions using immunohistochemistry on 52 cases of thyroid follicular adenomas and studied the follow-up records of these patients. The range of follow-up period was 3 to 14 years. The patients were between 15 and 71 years of age with a median age of 34.5 years. There were 46 females and 6 males. Except for 3 cases, all patients were Malays. The minimum volume of the tumour was 1000 mm3 and the maximum was 512,000 mm3 with a median of 270,000 mm3. Eleven (21.2%) cases showed RET expression. RET expression was not statistically significant when cross-tabulated against sex (p = 0.322), ethnicity (p = 0.518), age (p = 0.466) and symptom duration (p = 0.144). Six (11.5%) of 52 cases showed p53 immunopositivity. p53 expressions were also not significantly correlated to the clinical parameters above. There was no correlation between RET and p53 protein expressions. The only statistically significant finding was the association of tumour volume with duration of symptoms (p = 0.05). All patients are alive at the time of writing. 3 had recurrent goitre, 2 of these were diagnosed as colloid goitre while the third was a follicular lesion. One patient suffered from depression requiring anti-depressant treatment. In conclusion, unlike papillary carcinoma in which the roles of ret and p53 oncogenes are known, their roles in influencing the behaviour of follicular adenoma has not been ascertained.

Background: Hand, foot and mouth disease (HFMD) is caused by enteroviruses such as Coxsackie virus A16 (CVA16) and Enterovirus 71 (EV71). The diagnostic hallmarks are oral ulcers and maculo-papular or vesicular rash on the hands and feet. Severe form of this disease can lead to death due to neurological and cardiopulmonary complications. This case report aims to describe a fatal case of HFMD with minimal oral and skin manifestations. Case report: A four-year-old girl was brought to a hospital after suddenly becoming unresponsive at home. She had a history of fever and lethargy for three days prior to her demise. The patient, and five other children in her neighbourhood had been diagnosed to have HFMD at a local health clinic; the other children had recovered without complications. Results: Autopsy revealed a few punctate, sub-epidermal vesicles measuring 1 to 2 mm on the palm of her right hand and sole of the right foot, visible only with a magnifying glass. Internal examination revealed prominent nodularity at the oro- and hypopharynxes. The lungs were markedly congested and oedematous. Histopathology of the lung showed marked oedema and haemorrhage with mild pneumonic changes. Oedema with increase in macroglia and astrocytic proliferation were seen in the cerebral tissue, but no lymphocytic infiltration was evident. Enterovirus EV71 was detected by polymerase chain reaction in samples from the lung, cerebrospinal fluid and serum. The cause of death was given as HFMD complicated by pneumonia. Conclusion: Fatal HFMD may have minimal signs. A complete history, careful physical examination and relevant investigations lead to a diagnosis at post mortem examination. Awareness of the subtle signs and rapid deterioration associated with a fatal case of HFMD is a challenge to clinicians who encounter these cases.

We describe rare case of a 9-year old boy who presented with a two- week history of right ear discharge and mild fever. Contrast enhanced CT scan of the brain showed a lesion in the right cerebellopontine angle with mild enhancement mimicking early abscess formation. Involvement of the mastoid air cells pointing towards a radiological diagnosis of mastoiditis reinforced the diagnosis of an abscess. A magnetic resonance imaging (MRI) was planned for the patient but his conscious level deteriorated and patient slipped into coma warranting immediate surgical intervention. Intraoperatively, about 90% of the tumour was removed and the appearance of the tumour resembled that of an acoustic schwannoma but histopathology confirmed the diagnosis of a glioblastoma multiforme (GBM). MRI done post operatively showed lesion in the pons confirming the diagnosis of an exophytic pontine glioblastoma multiforme.

We described an intracranial immature teratoma in a 13 year old Malay boy who presented with history of chronic headache and blurring of vision. Physical findings revealed bilateral papilloedema but no other localizing sign. A Magnetic Resonance Imaging of the brain revealed a suprasellar well defined lobulated midline heterogenous mass which was intraoperatively described as mainly solid tumour with multiple small cystic component filled with yellowish jelly like material. Histopathological finding confirmed the case as immature teratoma. Molecular genetic analysis of p53 and p27 genes revealed substitution of nucleotide G to C at location nucleotide 12139, exon 4 of gene p53. No alteration was detected at exon 5-6 and 8 of p53 gene and exon 1 and 2 of p27 gene. This is the first case report of an intracranial immature teratoma with genetic mutation occuring in a Malay boy.

Sarcocystis sp. infection was investigated in 20 necropsied captive wild mammals and 20 birds in 2 petting zoos in Malaysia. The gross post-mortem lesions in mammals showed marbling of the liver with uniform congestion of the intestine, and for birds, there was atrophy of the sternal muscles with hemorrhage and edema of the lungs in 2 birds. Naked eye examination was used for detection of macroscopic sarcocysts, and muscle squash for microscopic type. Only microscopically visible cysts were detected in 8 animals and species identification was not possible. Histological examination of the sections of infected skeletal muscles showed more than 5 sarcocysts in each specimen. No leukocytic infiltration was seen in affected organs. The shape of the cysts was elongated or circular, and the mean size reached 254 x 24.5 micrometer and the thickness of the wall up to 2.5 micrometer. Two stages were recognized in the cysts, the peripheral metrocytes and large numbers of crescent shaped merozoites. Out of 40 animals examined, 3 mammals and 5 birds were positive (20%). The infection rate was 15% and 25% in mammals and birds, respectively. Regarding the organs, the infection rate was 50% in the skeletal muscles followed by tongue and heart (37.5%), diaphragm (25%), and esophagus (12.5%). Further ultrastructural studies are required to identify the species of Sarcocystis that infect captive wild animals and their possible role in zoonosis.

Although melatonin supplementation is known to influence numerous physiological functions, little is however known of its effects on pregnancy outcome. This study investigated the effects of melatonin supplementation on pregnancy outcome in Wistar-Kyoto (WKY) and Sprague-Dawley (SD) rats aged 12-13 weeks. Upon confirmation of proestrus, each female rat was housed overnight with a male of the same strain. On the next morning, following confirmation of mating (vaginal smear), WKY female rats were isolated into individual metabolic cages and given 0, 25, 50 or 100 mg/kg per day of melatonin in drinking water from day 1 of pregnancy to day 21 postpartum. SD females were given 0 or 100 mg/kg per day of melatonin. Maternal weight, duration of pregnancy, litter size, birth weight and body weight of pups up to day 42, and pup mortality were recorded. Data were analyzed using ANOVA for repeated measures. Compared to controls, maternal weight gain during pregnancy was significantly lower in melatonin-supplemented dams (P < 0.01). Litter size was significantly smaller in melatonin-supplemented dams (P < 0.01). Mean birth weight of pups was significantly lower only in pups of dams given 100 mg/kg per day of melatonin (P < 0.001). Mean body weight of pups of dams given melatonin was significantly lower than controls (P < 0.01). Pup mortalities were 9.5% and 21.6% in WKY dams given 25 and 100 mg/kg per day of melatonin respectively, and all pup deaths occurred after day 21 of weaning. The results suggest that melatonin supplementation during antenatal and postpartum period appears to adversely affect litter size, pup growth and mortality in WKY and SD rats. The precise mechanism causing the death is not clear.
