    Malaria is a major public health problem in tropical and subtropical areas, caused by five
    species of Plasmodium (P. falciparum, P. vivax, P. malariae, P. ovale andP. knowlesi) and is the leading cause of morbidity and mortality worldwide. We have developed molecular markers for three genes viz, Cytb, dhfr and Msp-1 gene and designed a protocol for rapid molecular diagnostics of the four malaria parasites prevalent in Southeast Asia. The new primers were used on the blood
    samples containing Plasmodium parasites by conventional PCR. The result was compared with
    the nested PCR of Singh et al. (2004) and the microscopy method. The result shows that the new
    set of primers had successfully amplified all four human malaria parasite species. These primers
    were 100% sensitive and more specific than microscopy and PCR identification using these
    primers was faster than the nested PCR. These alternative primers should provide powerful and
    rapid molecular diagnostic method for detecting Plasmodium species as well as providing reliable
    data for epidemiology study. These primers have the potential to be combined and used in
    multiplex PCR.

    Liver, an important organ of metabolism, is damaged when exposed to chemicals, toxins, infectious agents, drugs and food additives. Arachis hypogaea (peanut) being organic may have free radical scavenging activity, which could protect the liver from damage. Objective: To evaluate the effect of Arachis hypogaea on liver marker enzymes such as serum AST(aspertate transaminase) and
    ALT(alanine transaminase) and histology of liver in Wistar albino rats. Methods: Twenty healthy Wistar albino male rats (120 – 150 grams, 90 – 120 days old) were acclimatized for 14 days and divided equally into control group (n = 10) and experimental group (n = 10). Control group received standard pellet for 21 consecutive days. The experimental group received peanut powder 500mg/kg body weight/day; orally) mixed with food for the same period. All the animals were killed on 22nd day. Blood and liver samples were collected. Levels of serum AST, ALT and bilirubin were estimated and the liver was processed for histology. Results were statistically analyzed by
    2 sample t-test. Results: Final body weights were significantly (p

    Foot shape significantly varies with age, sex and ethnicity. Information on gender and racial differences in foot shape is also useful to forensic scientists identifying isolated remains. Literature survey revealed that there are not enough studies on correlation of foot shape with changes in body weight. Hence this cross-sectional and analytical study was carried out to evaluate the correlation of foot shape with changes in body weight within same race and ethnicity. A total number of 110 male medical students of 3rd and 4th year of Bengali ethnicity were chosen through purposive sampling. Foot index was calculated by dividing the foot length with the foot width. On the basis of foot index, foot shapes were classified into slender, standard and broad. Correlation of the foot shape with the body weight was assessed. Both right and left foot indices showed significant negative correlations with the body weight (r = −0.214, p = .033 and r = −0.282, p = 0.005 respectively). This approach of categorization will help in making best fit footwear for males. It will also serve as a baseline data for forensic investigators.

    Assessment method of medical students by conducting examination is to identify the quality and quantity of their academic performance. Essay paper is one of the most common assessment tools in the Faculty of Medicine and Health Sciences, Universiti Malaysia Sabah. Double marking is a means by which academic staff attempts to produce fair results for the students. Eighty eight medical students sat for three sets of Essay Papers of Professional I examination in March 2012. The double marking on the essay papers was done by two lecturers of each clinical department concerned for each discipline. Inter-examiner agreement and its effect on the reliability of the final score for the students were calculated by using Kappa statistics and Intra-class Correlation Coefficient (ICC). Reliability coefficient of the scores were also calculated for the different disciplines. In Part A essay paper, Cohan’s Kappa was 0.48 (p

    Galactorrhoea is non-lactational milk production and it may or may not be associated with prolactinemia1. It causes embarrassment and distress to a schizophrenic patient, especially, if the patient is male. One study in Germany reported that incidence and prevalence of galactorrhoea in schizophrenia are 14% and 19%, respectively2. Although galactorrhoea is not rare in schizophrenic patients, managing and understanding the a etiology can be problematic. In psychiatric patients, antipsychotics can be a cause but other causes need to be ruled out. Galactorrhoea also needs to be differentiated from pathologic nipple discharge which can be due to breast tumours. Usually, galactorrhoea is bilateral, multiductal, and milky, but discharge can be yellow, green or brown3. This case report describes a 32-year old patient with schizophrenia who visited a government psychiatric hospital in Kota Kinabalu, Sabah, Malaysia. This report highlights the clinical challenges to determine the aetiology of galactorrhoea and to manage it in schizophrenics. It raises the following clinical questions: Why a psychiatric patient develops galactorrhoea? How a schizophrenic patient presents with galactorrhoea? What hormonal imbalances are associated with this psychiatric disorder? How should a doctor handle a schizophrenic patient complaining of galactorrhoea? What is the danger of having galactorrhoea in a male?

    Escherichia coli sequence type 131 (ST131) carries multiple drug resistance (MDR) genes as well as virulence genes. Drug resistant characteristics give a management problem to health care personnel. Four MDR Escherichia coli ST131 H30-Rx subclones were identified among 80 Uropathogenic E. coli (UPEC) isolates by using 4 allelic-specific Polymerase Chain Reactions (PCR) in two hospitals of Kota Kinabalu, Sabah, Malaysia. There is emergence of multidrug resistant E. coli in Kota Kinabalu.

    Both metformin and gliclazide have been used extensively in the management of type II diabetes mellitus. Metformin and gliclazide overdose can lead to severe hypoglycaemia refractory to intravenous (IV) dextrose rescue therapy. A 21-year-old man complained of vomiting and felt dizzy after four hours of taking 70 tablets of Metformin 500 mg and 40 tablets of Gliclazide 80 mg. He had major depressive disorder and wanted to commit suicide. He was given IV Dextrose 50% 50 cc immediately. Octreotide had been used successfully to reverse the refractory hypoglycaemia caused by gliclazide overdose. Unfortunately, he developed severe lactic acidosis with acute kidney injury. Dialysis had been done by continuous venovenous haemodiafiltrationa and intravenous sodium bicarbonate 8.4% infusion was given. However, the patient succumbed due to the severe lactic acidosis and kidney failure despite of urgent dialysis. Octreotide infusion helps in preventing refractory hypoglycaemia secondary to sulfonylurea overdose by inhibit calcium-mediated insulin release. Metformin overdose causes severe lactic acidosis due to conversion of glucose to lactate. Sodium bicarbonate therapy in metformin induced lactic acidosis is also controversial. Though sulfonylurea and metformin are the most commonly-prescribed anti-hypoglycaemic agents, thus during prescribing everyone has to be careful about the overdoses and side effects of these drugs.

    Colonic lipomatosis is relatively a rare tumour of mesenchymal origin, composed of welldifferentiated adipocytes interlaced by fibrous tissues. A 59-year-old lady presented with right iliac fossa pain with positive rebound tenderness, Rovsing’s and obturator signs. Investigation revealed marked leucocytosis suggestive of an acute appendicitis. Diagnostic laparoscopy revealed an inflamed appendix with concomitant caecal mass suspecting of a malignancy. Laparoscopic right hemicolectomy was proceeded following oncologic resection. However, final histopathologic examination was consistent with caecal colonic lipomatosis with concomitant acute appendicitis. Hereby, dual pathologies can be elicited in an acute abdomen.

    Fat embolism syndrome is manifested by the fat globule presence in the pulmonary and systemic circulation. A 34-year-old man was involved in a motor vehicle accident with a fracture of the left femur and avulsion fracture of the left posterior cruciate ligaments. He developed signs and symptoms that suggested an early diagnosis of fat embolism syndrome. Intravenous methylprednisolone administration was administered as part of the treatment. The role of methylprednisolone in a patient with fat embolism syndrome is controversial due to unproven effectiveness. In this case, fat embolism syndrome after a femur fracture was treated successfully with methylprednisolone.

    Learning anatomy is the basic and essential component of medical study when students start to learn in medical career. Since five hundred years ago, the human cadaver has been used as the silent mentor for students in learning anatomy. Later, pre-dissected specimens were used in addition to hands-on dissection of human cadaver. Current advances promote the use of anatomical models as well as plastinated specimens. This study focused on analyzing the preference of students towards different learning modalities available for anatomy teaching. It was conducted on first year medical students at the Faculty of Medicine and Health Sciences, University Malaysia Sabah (FPSK, UMS). A total of 76 students (27 males and 49 females) participated in this study. Out of 76 students, 57 (75%) students preferred using human cadaver for anatomy learning. Four students (5.3%) opted for plastinated
    specimen while 15 students (19.7%) chose the plastic model. Knowledge gained in learning Anatomy was said to be easier from cadaver (67.1%), followed by plastinated specimen (35.5%) and plastic models (52.6%). In the present study, 97.4% responded that plastic model was easier to apply their knowledge in objective structured practical examinations. The present study found that using cadaver was still favoured by medical students. Further studies are required to determine the preference between hands-on cadaveric dissections versus pre-dissected specimens.

    Escherichia coli (E. coli) is one of the most frequent causes of many bacterial infections especially
    gastroenteritis in developing countries. It is also used as an indicator for faecal pollution in the
    surveillance of bacteriological quality of drinking water. This study was conducted to determine the
    survival of E. coli in water at room temperature (27oC). E. coli which is cultured in Lactose Peptone Broth
    was inoculated into 8 bottles each containing 10 millilitres of distilled water. They were kept at 27oC.
    Starting from the day 1, ten-fold dilutions were made from each bottle number and E. coli count was
    done from each dilutions by using pour plate method. The colony forming unit/ millilitre (CFU/ml) was
    calculated. The same procedure was carried out from bottles number 2 to 8 from day 2 to day 8
    consecutively. CFU/ml of E. coli in dilution 10-5was markedly decreased from 3.9 x 106
    in day 1to 0 in
    day 8. The findings suggest that if the water is contaminated with low number of E. coli, it can be
    eliminated by keeping water at room temperature for only few days.

    Antenatal (AN) care is vital for all pregnant women and for reduction of maternal mortality and morbidity. AN care knowledge and specific AN care practices are some of the crucial components of what determines effective AN care. In developing nations, the health of pregnant women can be even more sensitive to these factors. Objectives of this study was to assess the antenatal (AN) care practice and pregnancy outcome of ever-married women aged 18 to 49 years old having at least one pregnancy experience ,residing in kampongs of Sikuati area, Kudat between March to December 2015. Cross–sectional descriptive study, non-probability convenient sampling method was used and 150 eligible participants were interviewed through face to face by trained interviewers using a semi-structured questionnaire and their knowledge of AN care, their AN care practices and outcomes and complications of their pregnancies were recorded. 99% of all the women received AN care, and 64% of the women received essential AN care practice (AN visit of minimum 4 times). The study revealed that overall knowledge amongst the women with good knowledge was 48% and low knowledge was 52%. Despite this, it was found that low knowledge of AN care was associated with essential AN care practice. Additionally, AN care practices, assessed through timing of first AN care visit and frequency of visits, was not significantly associated with pregnancy complications. Despite these results, outcomes were good and all complications were properly and successfully addressed. This may reflect the effectiveness of current programs in place promoting importance of AN care and delivery practices. Maintenance of current programs with targeted interventions to address low knowledge level and the low level of compliance with essential AN care completed are recommended..

    The Emergency Department (ED) provides treatment for acutely ill patients in need of urgent medical attention. Despite the availability of the primary care unit ‘Klinik Kesihatan’, where non urgent patients should be treated, Malaysia’s public hospitals still need to deal with overcrowding of non-urgent patients in ED. The main aim of the study was to assess the willingness of non-urgent patients to be redirected to Klinik Kesihatan. This was a cross-sectional study conducted at Hospital Tuaran Emergency Department, Sabah. Non-urgent patients were interviewed using a questionnaire, to find out the purpose of their visit to Emergency Department. A total of 318 non-urgent patients out of 457 patients were interviewed during the study duration. 41 respondents (12.9%) were willing to be redirected towards a Klinik Kesihatan. No associated factors were found when compared with the unwilling to be redirected group. Among 277 respondents who rejected redirection to Klinik Kesihatan, 70.4% agreed to pay a surcharge to be treated in the Emergency Department and there was no association found with the employment status (p= 0.391). Most patients were not willing to accept redirection to a Klinik Kesihatan and would prefer to visit the Emergency Department despite knowing that their condition or illness is one that does not require emergency treatment. Social media, advertisements and pamphlets must be made available to educate patients on the proper use of the Emergency Department.

    Prenatal exposure to chronic stress during critical periods of foetal development produces depression, attention and learning deficits, hormonal imbalances and affects the brain. The effect of prenatal restraint-stress on the postnatal developmental milestones, anthropometric measurements, and the body, brain and adrenal gland weights of the pups were examined and compared with the unrestrained control and the restrained group under the pyramid at postnatal day 10 and 21. Pregnant rats were restrained (9h/day) from gestation day 7 until parturition. Results showed significant delay in the milestones by one day in the restraint control (RC) compared to the unrestrained normal control (NC), while pups of the restrained pyramid (RP) group did not show the delay. Significant decreases in the anthropometric measurements, body and brain weights in RC group were observed at both postnatal days, while the RP group results matched with the NC group. Significant increase in the adrenal weights was found in the RC group compared to NC group and not the RP group. Results suggest prenatal restraint-stress definitely hampers the developmental milestones, anthropometric measurements, and body and brain weights of the young offspring. Results suggest, pyramid environment counteracts and protects the deleterious effects of chronic prenatal stress.

    Diabetic amyotrophy also known as Bruns-Garland syndrome is diabetic neuropathy subtype affecting the lumbosacral nerve roots and peripheral nerves. There is an ongoing debate on the pathophysiology behind this condition whether is it ischaemic, metabolic (hyperglycaemia) or inflammatory. A 36-year-old man with uncontrolled diabetes mellitus complained of unprovoked weight lost and right proximal thigh discomfort with weakness for one week duration. In neurological examination, his right hip flexion was at medical research council (MRC) grade 3, right hip extension MRC grade 4, his knee and ankle flexion and extension are normal (MRC grade 5). The muscle tones and reflexes were normal. Sensation and proprioception were intact bilaterally. Nerve conduction study (NCS) showed markedly reduced amplitude of the compound muscle action potentials and sensory nerve action potentials, while conduction velocities show only mild slowing. He was started on a course of oral prednisolone 10 mg daily and improved gradually. At three months follow-up, his right lower limb power has recovered fully and he can walk without any assistance. Diabetic amyotrophy was confirmed by suggestive clinical features supported by electrophysiological findings of the affected nerves. This condition is due to metabolic derangement and vasculopathy or immune mediated nerve injury. So, the healthcare providers should be aware about this rare complication of diabetes.

    Electrocardiogram (ECG) is a record of electrical activity of the heart. PQRST waves represent
    the electrical activities of atria and ventricles. A complete three-dimensional electrical activity is
    possible to be recorded using a 12-lead ECG. The normal and different routinely-met clinical ECG
    are elaborated and discussed. This routine, normal and abnormal ECG, like arrhythmias and heart
    block records as well as their clinical notes shall be educational information for the medical students.

    Evidence-based data confirm the relationship between an increased availability of effective contraception and reduction in induced abortion rate. In Malaysia, the contraception prevalence rate in 1966 was 8.8 per cent to 52 per cent in 1984, but has levelled off since then. In recent years there has been increasing report of babies ‘abandonment’ in Malaysia. The aim of this study is to determine the knowledge, attitudes and practices related to contraception among women and doctors in Kota Kinabalu the capital of Sabah, Malaysia. Descriptive and analytical community-based cross-sectional study was used. A total of 240 women and 60 doctors were selected from either private or public clinics. The instrument used was face-to-face interview for the women and self-administered questionnaires for doctors. Analysis was done using SPSS version 21. The doctors (80%) felt that contraception is extremely important, and routinely discuss (63%) with their patients. Oral contraceptive pill (97%) is the most common type of contraceptive available in their clinics. About 68% of doctors surprisingly cited that abstinence plays a major part in their contraceptive advice. The average correct answer by doctors on knowledge is 62%. The women surveyed (98.8%) have heard of contraception. The main reason for using is for spacing of pregnancy and many stopped or did not use because of fear of side effects. Women attending the public clinic appear to know more about female and male sterilization and intrauterine contraceptive device compared to those attending private clinic. Further research is needed to reinforce this study.
