Metabolic syndrome (MetS) is the physiological clustering of hypertension, hyperglycemia, hyperinsulinemia, dyslipidemia, and insulin resistance. The MetS-related chronic illnesses encompass obesity, the cardiovascular system, renal operation, hepatic function, oncology, and mortality. To perform pre-clinical research, it is imperative that these symptoms be successfully induced and optimized in lower taxonomy. Therefore, novel and future applications for a disease model, if proven valid, can be extrapolated to humans. MetS model establishment is evaluated based on the significance of selected test parameters, paradigm shifts from new discoveries, and the accessibility of the latest technology or advanced methodologies. Ultimately, the outcome of animal studies should be advantageous for human clinical trials and solidify their position in advanced medicine for clinicians to treat and adapt to serious or specific medical situations. Rodents (Rattus norvegicus and Mus musculus) have been ideal models for mammalian studies since the 18th century and have been mapped extensively. This review compiles and compares studies published in the past five years between the multitude of rodent comparative models. The response factors, niche parameters, and replicability of diet protocols are also compiled and analyzed to offer insight into MetS-related disease-specific modelling.

Fulltext Longitudinal effects of common carotid artery stenosis on ocular hemodynamics assessed using laser speckle flowgraphy in a rabbit model

Ismail A, Chen HC, Faye I, Tang TB

Sci Rep, 2020 09 28;10(1):15829.
PMID: 32985560 DOI: 10.1038/s41598-020-72556-9

Real-time impairment of ocular blood flow (OBF) under common carotid artery stenosis (CCAS) has not been ascertained. We aimed to longitudinally assess the impact of CCAS on OBF using a rabbit model. About 75% stenosis was created by tying the common carotid artery with a plastic mandrel using a nylon suture. The plastic mandrel was gently removed, leaving a ligature. Neurological and behavioral assessments were recorded as the clinical indicator of stroke severity. With laser speckle flowgraphy, the pulse waveform parameters namely mean blur rate (MBR), blowout score (BOS), blowout time (BOT), rising rate, S1-area, falling rate (FR), S2-area, flow acceleration index (FAI), acceleration time index, resistive index (RI) and the difference between the maximum and minimum values of MBR (AC) were assessed in overall, vessel, and tissue regions of the optic nerve head (ONH). Longitudinally, BOS significantly increased until day 19 post-surgery, whereas FAI, RI, and AC significantly decreased. Beyond day 19, BOS, BOT, FR, FAI, RI, and AC significantly decreased. We defined two stages representing impaired vessel conditions, namely the vessel resistance phase, where BOS increases and FAI, RI, and AC decrease, and the vessel elasticity phase where BOS, BOT, FR, FAI, RI and AC decrease. These stages provide information about atherosclerosis, assessable non-invasively through the eye.

BACKGROUND: Tumor necrosis factor superfamily member 4 (TNFSF4) has significant role in modulating autoimmune diseases (ADs) and single nucleotide polymorphism (SNP) is also related with the susceptibility to some diseases. So a meta-analysis aimed at systematically assessing the associations between TNFSF4 polymorphisms (rs2205960 G > A, rs704840 T > G and rs844648 G > A) and ADs risk was performed in Asians.
METHODS: Total 14 eligible articles published before March 2019 involving 35 studies, of which 21 studies (16,109 cases and 26,378 controls) for rs2205960 G > A, 8 studies (2,424 cases and 3,692 controls) for rs704840 T > G, and 6 studies (3,839 cases and 5,867 controls) for rs844648 G > A were included. Effects of the three respective polymorphisms on the susceptibility to ADs were estimated by pooling the odds ratios (ORs) with their corresponding 95% confidence interval (95% CI) in allelic, dominant, recessive, heterozygous and homozygous models.
RESULTS: The overall analysis revealed that all the rs2205960 G > A, rs704840 T > G and rs844648 G > A polymorphisms could increase the risk of ADs in allelic, dominant, recessive, heterozygous and homozygous models. Furthermore, subgroup analysis showed that both rs2205960 G > A and rs704840 T > G were significantly associated with the susceptibility to systemic lupus erythematosus (SLE). What's more, statistically significant association between rs2205960 G > A polymorphism and primary Sjögren's syndrome (pSS) susceptibility was also observed in allelic, dominant and heterozygous models.
CONCLUSIONS: This current meta-analysis suggested that all of the three TNFSF4 polymorphisms may be associated with ADs susceptibility in Asians.

Tuberculosis (TB) is a leading cause of morbidity and mortality in Thailand. Cytokines play important roles in defense against Mycobacterium tuberculosis infection. Interleukin (IL)-4 is one of the anti-inflammatory cytokines and has been found to be elevated in TB patients. The common polymorphisms in IL-4 gene, including IL-4-590C/T, IL-4-33C/T, and IL-4-variable number of tandem repeats (VNTR) intron 3 have been reported to be associated with risk for some diseases. The purpose of this study was to investigate possible associations between the above mentioned three common functional polymorphisms in the IL-4 gene in patients with pulmonary tuberculosis (PTB) in a Thai population. Forty three patients with PTB and 90 healthy control subjects were studied. The three common polymorphisms of the IL-4 gene were determined using polymerase chain reaction (PCR) and PCR-restriction fragment length polymorphism (PCR-RFLP). The allele and genotype frequencies of IL-4 -590 C/T, -33 C/T, VNTR intron 3 polymorphisms did not show significant differences between PTB patients and healthy controls (genotype: p=0.88, p=0.92, p=0.40; allele: p=0.38, p=0.44, p=0.53, respectively). However, the allele distribution of the IL-4 -590 C, -33 C, and VNTR R3 was higher among PTB patients (25.58%, 25.58%, 25.58%, respectively) than among control subjects (20%, 20.48%, 19.44%, respectively). This may suggest that IL-4-590C/T, -33C/T and VNTR intron 3 might play a role in susceptibility to PTB. A larger cohort may possibly help conclude our findings.

Report of a 3-month old girl child who died due to multi-systemic infection of cytomegalovirus (CMV) involving the lungs, liver and kidneys along with pneumocystis jiroveci pneumonia (PJP). The mother of the child tested positive for CMV IgG and HIV with a very low CD4 count (160/ μl). Co-infection of cytomegalovirus and pneumocystis jiroveci always occurs in the setting of immunocompromise. Congenital CMV infection is transmitted through the placenta, especially during the first trimester and causes severe multi-systemic disease whereas perinatal infection is acquired during childbirth/ breastfeeding where the babies have maternal protective antibodies leading to much milder or asymptomatic infection. PJP is more common in infancy and presents as hypoxic pneumonia. CMV causes cyto-nucleomegaly and classic "owl's eye" inclusions on histology while PJP presents with characteristic fluffy "cotton ball" alveolar exudates.

Shiga toxin-producing E. coli (STEC) is an important foodborne pathogen causing diarrhea, hemorrhagic colitis and hemolytic-uremic syndrome in humans. STEC is an implicated in the vast majority of outbreaks, widely via consumption of STEC contaminated beef, as important vehicle of transmission of this organism to human. The E. coli O157:H7 serotype is traditionally identified by serological identification of the somatic antigen (O157) and structural flagella (H7). In this study, the bacteria were identified as STEC serotype O157:H7 with three primer pairs that amplified fragments of secD, rfbE and fliC genes in PCR assays. These primer pairs specifically amplified different sizes of target genes: a 244bp region of the E. coli diagnostic marker gene (secD); a 317bp region of the O157 lipopolysacharide (LPS) gene (rfbE); and a 381bp region of the H7 flagellin gene (fliC). The singleplex, duplex and triplex PCR assay developed in this study have a sensitivity limit at 2.8 x 103, 2.8 x 105 and 2.8 x 107 CFU/ml of E. coli O157:H7, respectively. Sensitivity to detect trace amount of E. coli O157:H7 DNA was reduced as the number of primer used was increased for competing to the same DNA template.

PMID: 27476173 DOI: 10.1159/000448296

Autosomal Dominant Polycystic Kidney Disease (ADPKD) is a systemic disease characterised by the formation of multiple renal cysts that adversely affect renal function. ADPKD shows significant progression with age when complications due to hypertension are most significant. The activation of the renin-angiotensin-aldosterone system (RAAS) occurs in progressive kidney disease leading to hypertension. The RAAS system may also contribute to ADPKD progression by stimulating signalling pathways in the renal cyst cells to promote growth and deregulate epithelial transport. This mini review focuses on the contribution of the RAAS system to renal cyst enlargement and the potential for antagonists of the RAAS system to suppress cyst enlargement as well as control ADPKD-associated hypertension.

The present study aimed to determine the factors associated with CKD stage 3b among type 2 diabetics attending primary care follow-up, specifically the role of angiotensin blockade dosage. This was a pilot unmatched case-control study conducted in a teaching primary care centre. Clinical data of 25 cases of diabetic patients with CKD stage 3b (GFR 30-45ml/min/1.73m2) in 2012 were selected for this study, as well as 103 controls who were diabetic patients with GFR more than 45ml/min/1.73m2 in 2012. Systematic random sampling was employed. Data was obtained from patients’ diabetic records, computerised clinical medical information system and medical case notes. Univariate analysis was done using Chi-square, t-test, Fisher’s exact test and Mann-Whitney U-test. Multiple logistic regression was used to determine the associated factors for development of CKD stage 3b. Cases and controls were different in terms of age, duration of diabetes, use and dosage of angiotensin blockade medications, systolic blood pressure and baseline GFR. Multiple logistic regression revealed that systolic blood pressure (Adjusted OR= 1.08, 95% CI= 1.02-1.14, p=0.013) and baseline GFR (Adjusted OR= 0.90, 95% CI= 0.85-0.95, p

Breast cancer is the commonest female cancer in Malaysia with a prevalence of 86.2 cases per 100,000 women in 1996. Pronling breast cancer patients is important for better planning of preventive and screening strategies for Malaysian women. The aims of this cross-sectional study were to identify histological presentation, socio-demographic and reproductive characteristics and prevalence of risk or protective factors of breast cancer among women with breast cancer in Kelantan. A total of 175 female breast cancer patients who were diagnosed in 1991 to 2000, were interviewed using standardized questionnaires. The mean (sd) age was 47.0 (9.6) years with 77.7% Malay, 20.6% Chinese and 1.7% others. About half (52.6%) had 9 years or less of formal education, while 59.4% were housewives/unemployed and 60.6% had a monthly family income of less than RM1 ,000. The commonest histological type was innltrative ductal carcinoma (73 .7%) . Presentation of breast cancer with the stage lll or Vl was 59.4%. The prevalence of nulliparity · 13.1%, breastfeeding longer than two years - 58.9%, premenstrual period - 72.0%, menarche at 11 years old or less - 5 .7%, positive family history - 14.4%, overweight/obesity - 48.0%, oral contraceptives use 30.3%, hormone replacement therapy » 1.1%, cigarette smoking - 4.6%, consuming akohol - 3.4%, previous benign breast disease - 6.3%, previous breast biopsy - 2.9% and previous oophorectomy - 4.6%. The patients were younger compared to other studies. The ethnic distribution did not represent the population distribution of Kelantan. The prevalence of overweight/obesity and smoking were higher than the national prevalence among women, thus they should be included in the prevention strategies for breast cancer. Further studies are recommended to investigate why many of breast cancer patients in Kelantan presented at a younger age and at advanced stages of cancer.

Choriocarcinoma is a malignant proliferation of syncytial trophoblast cells that do not form placental villi. It is a relatively rare and highly malignant variant of gestational trophoblastic disease. Although choriocarcinoma is mostly observed after a molar pregnancy, it may be preceded by any gestational event. It has been shown that even a partial mole can transform into choricarcinoma. Incidence rates of choriocarcinoma differ widely throughout the world. In Europe and North America, choriocarcinoma is reported to affect one in every 30,000 to 40,000 pregnancies, and one in 40 molar pregnancies. In South East Asia, choriocarcinoma is reported to affect one in every 500-3000 pregnancies. Following livebirth, choriocarcinoma with metastatic disease are important sequele (31%)(Tidy et al 1995). In the same study the reported median interval between antecedent pregnancy and choriocarcinoma is five months. Multi agent chemotherapy is required in the majority of patients (82%) for the high risk group. The prognosis for choriocarcinoma after a normal gestation is poorer. The mortality rate is also significantly higher than non-molar abortion (21%). Effective treatment with oral Methotrexate in metastatic choriocarcinoma to the lung confirmed the highly sensitive nature of this tumour to chemotherapy agent.

The use of thrombolytic agent e.g. streptokinase is indicated in patients with early acute ST elevation myocardial infarction (MI) (if there are no contraindications) is becoming increasingly routine. Its use is however significantly limited by bleeding complications. Spinal epidural haematoma (SEH) is haemorrhage in the spinal epidural space after spinal anaesthesia. SEH may be acute or chronic, spontaneous, posttraumatic, or iatrogenic but its occurrence appears to be particularly associated with acquired coagulopathy from medications and disease states. Patients usually present with acute axial spine pain and evolving focal neurological deficits. With increasing number of available anticoagulants and patient receiving them, anaesthesiologists today have to face the challenge of balancing between risks and benefits of regional anesthesia in patients under such medications. The treatment of this condition involves the principles of conservative follow-up directed by an improving examination and an understanding of the pathophysiology of coagulopathy-induced spontaneous epidural bleeds. When the diagnosis is accomplished rapidly, surgical decompression can result in full functional recovery.

Pelvic inflammatory disease (PID) is a common cause of morbidity and accounts for 1 in 60 GP consultations by women under the age of 45 in the UK. Pelvic inflammatory disease encompases a broad category of disease including endometritis, salphingitis, salphingo-oopheritis, tuboovarian abscess and pelvic peritonitis. It most commonly occurs as a result of Chlamydia trachomatis or Nesseria gonorrhea 1,2 infection of the endocervix that eventually spread into the upper genital tract. Direct spread from a nearby infection such as appendicitis and diverticulitis is not that common. Hematogenous spread is rare except in cases of tuberculous pelvic inflammatory disease. This case illustrates atypical presentation of pelvic inflammatory disease in a previously healthy single unmarried lady. The presence of ascites, bilateral ovarian mass and constitutional symptoms closely mimics that of malignant ovarian tumour. This was preceded by empyema which grew E coli.

Little is known about the sero-prevalence of diphtheria anti-toxoid antibody levels among medical students in Malaysia. They too, just like other health care workers (HCWs) are at risk of contracting and transmitting diphtheria. Fortunately, this can be prevented by giving a specific vaccine: the diphtheria, tetanus and pertussis (DTP) vaccine. Nonetheless, data from local or regional surveys are needed before any decision is made by the respective authorities. General objective: We studied the epidemiology of diphtheria anti-toxoid antibody levels and vaccination history amongst medical students and staff in Faculty of Medicine and Health Sciences, Universiti Putra Malaysia. Specific objectives: We determined the level of diphtheria anti-toxoid antibodies amongst pre-clinical students and staff. Methodology: A total of 152 sera were collected from subjects aged 19 to 63, and diphtheria anti-toxoid levels were measured by an enzyme-linked immunosorbent assay. Results: One hundred and fifty-two (94.4%) blood samples out of 161 participants were successfully withdrawn, which comprised 105 (69.1%) and 47 (30.9%) medical students and staff, respectively. A total of 77.6% and the other 22.4% of the subjects had full and basic protection, respectively. Higher levels were predominant amongst males and they were 1.3 times more protected than females in 20-29 year-old group (85.1% vs 66.2%; odd ratios 1.25 [95% CI 1.03-1.50]; P=0.03). No significant difference in the levels of immunity among subjects for ethnicity and academic position (P>0.05). Recommendations: Level of full protection against diphtheria toxin should be clearly defined by broad population based studies using several comparable detection methods. Medical students and staff with basic protection should be closely monitored or should be given a booster dose for those who are at high risk of acquiring the disease. Thus, a standard degree of coverage should be clearly determined for health workers to prevent a potential outbreak. Conclusion: Students and staff possess immunity towards diptheria toxin however the level of full protective antibody is yet to be determined in future.

MyJurnal

Intravenous immunoglobulin (IVIG) therapy in Kawasaki disease (KD) has been shown to reduce coronary artery aneurysm by 4-5%. However, we still observed significant number of coronary aneurysm post IVIG in our centre. The objectives of this study were to determine the prevalence of coronary artery abnormality (CAA) and the associated risk factors.
Designs: Retrospective descriptive study. Method: A retrospective study performed on children with KD from 1 st January 2005 to 30 th July 2010. Japanese Ministry of Health criteria were used to classify coronary arteries abnormality. Children with incomplete or atypical KD were excluded. Data were extracted from Pediatric Cardiology Clinical Information System.
Results: A total of 126 KD were diagnosed during the study period with 69% were male and 52.4% were Chinese. The median age of diagnosis was 1.4yr [Q1, 0.6yr Q3, 2.3yr]. Of these 126, 118 (93.7%) received IVIG within 10 days of illness. Ten patients (7.9%) required more than one dose of IVIG. CAA were noted in 28 (22.2%) patients with 21 ectasia, 4 small fusiform, one small saccular and 2 medium fusiform aneurysm. Of these 28, 22 who had IVIG within 10 days of illness (18 ectasia, 3 small and one medium coronary aneurysm) Significant risk factors for CAA were older children (2.3 v s 1.7yr, p=0.03), presentation after 10days of illness (p=0.006) and required more than 2gm/kg of IVIG (p=0.04).
Conclusion: CAA in complete KD treated with IVIG was 22.2% with 5.5% significant aneurysm. Risk factors for coronary abnormality were older children, late presentation and require more of IVIG of than 2gm/kg.

MyJurnal

Even though vaccines are effective for prevention of diseases, compliance with recommended schedules of immunisation in early childhood is not always complete. Identification of potential risk factors associated with under-immunisation may help increase vaccination uptake. The objectives of this study were to determine the prevalence and risk factors of under-immunisation in hospitalised preschool children in Universiti Sains Malaysia Hospital (HUSM). Children aged 1 month to 2 years admitted between December 1998 and December 2000 in medical paediatric wards at HUSM were studied. Parents/guardians were interviewed during admission regarding immunisation status and potential risk factors. Children who did not have home-based cards during admission were excluded. Among 401 children, 37.9% had complete immunisation, 43.4% had delayed immunisation and 34.9% had incomplete immunisation. The uptake of BCG, DPT/OPV 1, DPT/OPV2, Hepatitis B3, DPT/OPV3, and measles were 98.5%, 90.7%, 83.2%, 81.4%,79.2% and 72.9% respectively. Vaccines scheduled to be given at later ages were significantly less likely to be taken (p=0.002) compared with vaccines scheduled to be given at an earlier age. Significant independent risk factors for under-immunisation were elderly mothers (3 40 years old) (OR 3.0, 95% CI: 1.2-8.0), low birth weight £2.0 kg (OR 6.2; 95% CI: 1.8-21.4) and presence of chronic illness in the child (OR 4.5; 95% CI: 2.5-7.9). In children whose father's education was low (primary school or no education), low maternal education was significantly associated with lower rate of under-immunisation (p = 0.005, OR 0.11 95%CI 0.02-0.51).
In conclusion this study showed that a large proportion of hospitalised preschool children were under-immunised, and vaccines scheduled to be given at a later age had lower uptakes. The situation can be rectified if every opportunity is taken to immunise all children, who have lapsed in their immunisation schedule.

Accepted 10 August 2011.
Introduction Cervical cancer (CC) is the second most prevalent female cancer in Malaysia. Almost 70% of its’ causal factors are attributable to oncogenic human papillomavirus (HPV) types 16, 18 and other risk factors. HPV genotypes distributions are also noted to differ by geographical area.
Methods This was cross sectional study conducted in 2007, to determine the influencing factors of HPV positivity and prevalence of HPV infections among patients with cervical cancer in Universiti Kebangsaan Malaysia Medical Centre (UKMMC). Patients’ paraffin-embedded cervical tissues kept in the Pathology Department from 1999 to 2007 were randomly selected. A total of 81 medical records with complete information were chosen as samples and patients were contacted for consent. Tissue samples were further derived for PCR DNA for HPV genotyping. Analyses included descriptive statistics; bivariate χ2 test and correlation were used to determine relationship between factors and HPV positivity. Significance level of less than 0.05 was taken as statistically significant.
Results Mean age of cancer diagnosis was at 52 ± 12.2 years. Women of Chinese ethnicity was the highest ethnicity to be HPV positive at 65.4% and squamous cell carcinoma was more commonly found (59.3%) compared with other types of cancers. The prevalence of HPV positivity was 92.6% with type 16 being the most common (74.1%), followed by type 33 (30.9%) and 18 (22.2%). Multiple HPV infections were a common finding at 54.3%. Factors thought to influence positivity i.e. age of intercourse, number of sexual partners, number of parity, smoking status of patients and their partners, oral contraceptive usage, presence of chronic illnesses and cancer stage were not significantly associated with HPV positivity. Increased CC severity level was not associated with increased number of HPV infections (Pearson correlation 0.58; p =0.607).
Conclusions High HPV positivity at 92.6% was found among ICC patients. Factors thought to influence HPV positivity were not significant. The top three HPV genotypes were type 16 followed by type 33 and 18. However, local women HPV serotypes findings need to be replicated in a larger population sample.

The state of Johore, Malaysia had been hit by the worst flood in the Malaysian modern history on the 19th December 2006 (first wave) and the 12th January 2007 (second wave) affecting all the eight districts. A total number of 157,018 and 155,368 Johore population had been displaced by the first and the second wave event respectively. The Johore State Health Department activated the Flood Action Plan which include mobilising medical teams to conduct daily clinical examinations on the flood victims and health teams to inspect flood relief centres, food premises and homes at flood-hit areas with regard to prevent and control communicable diseases. The spreadsheet format was used to collect data on diseases, injury and death throughout the Johore flood disaster period starting from the 19th December 2006 until 19th February 2007. Analyses showed that 19,670 flood victims (36.3%) had communicable diseases and 34,530 (67.0%) had non-communicable diseases. As for the communicable diseases and symptoms/syndromes related to communicable disease, 41.3% were acute respiratory infections (ARI) followed by 25.9% skin infections, 19.1% fever, 10.1% acute gastroenteritis (AGE) and 3.0% acute conjunctivitis. Other infectious diseases include 61 notifiable diseases (46 food poisoning, 14 dengue fever and one tuberculosis), 20 leptospirosis (with two deaths), 20 chicken pox and two melioidosis cases. The Batu Pahat district had the highest incidence for the majority of the communicable diseases because of the prolonged flooding period. No cholera, typhoid, malaria, measles or hand-foot-mouth disease (HFMD) cases were detected among the Johore flood victims. Trends of disease incidence follow the number of evacuees placed in the relief centres corresponding to respective wave. A total of 507 flood victims had physical injuries related to flood mostly due to fall onto wet floor at the relief centres. Fifteen deaths due to drowning were mainly caused by accidental fall into the flood water. The incidence of communicable diseases encountered had been appropriately anticipated and managed attributed to enhanced public health control programmes augmented by syndromic and laboratory surveillance on potentialy fatal infectious diseases. Equal emphasis should be given to the surveillance and control of chronic diseases.

Background : Safe potable water is critical during and post flood. In the pre-flood period, Johore has an excellent, systematic and comprehensive water supply system. More than 98.6% of Johore population received treated water supply from the water treatment plants.
Methodology : Data collection was performed by conducting additional water sampling at routine sampling stations as well as the flood relief centres, water tankers (lorries) and static water tanks. Water treatment plant outlet and water tanker inlet shall have a minimum level of 2.0 mg/l of residual chlorine so that reticulation, water tanker outlets and static water tanks would have at least 0.5 mg/l as a measure to prevent the incidence of water borne diseases. Sampling was done everyday to monitor water quality at the flood relief centres as well as flood-hit areas. Inspections and surveillance on sanitation were also conducted on latrines, solid waste disposal systems and on the surrounding environment.
Results : A total of 6,283 water samples had been collected during and post flood. Violations on E. coli, turbidity and residual chlorine were 0.8%, 0.6% and 4.0% respectively with the Kluang district recorded the highest percentages for all the three parameters. A number of 621 wells had been inspected with 378 of them (60.9%) had been chlorinated. In order to ensure environmental cleanliness, 26,815 houses in 708 villages had been visited. Out of them, 2,011 houses (7.5%) were not satisfactory. Sanitation inspections found that 1,778 latrines, 2,719 domestic water sewerage systems and 2,955 solid waste disposal systems were under substandard conditions thus remedial actions had been taken immediately.
Conclusion : Although the flood disaster was massive with prolonged flooding period, however, an overall quality status on treated water supply was satisfactory whilst sanitary hygiene was under control. Hence, the incidence of communicable disease especially water borne diseases would not progress into serious outbreak, in fact, neither cholera nor typhoid was reported during the Johore flood disaster.

Background and Objective : Johor was affected by the worst flood in 100 years in December 2006 and again in January 2007. The concern that improper sanitary facilities and contaminated water supply at relief centres would result in contaminated food made monitoring of food hygiene vital. The objective of this paper is to describe food hygiene surveillance activities carried out in flood relief centres and flood affected areas and the challenges faced in carrying out these activities.
Methodology : The food hygiene surveillance activities were carried out by the Assistant Environmental Health Officers (AEHO) in the districts. Among the surveillance activities carried out are inspection of food preparation areas in relief centres, inspection of food premises in flood affected areas and food sampling. Premise inspections were carried out using a specific inspection format. Food samples taken were sent to Public Health Laboratory, Johor Bahru for microbiological analysis. Anti typhoid vaccination for food handlers were also carried out. Apart from that, observations made by the health teams were alsotaken into account.
Results : A total of 3,159 food preparation areas in relief centres were inspected. During the same period, a total of 2,317 food premises in flood affected areas were inspected as soon these premises started operating after the floods. Inspections showed that 69 food preparation areas in relief centres and 181 food premises in flood affected areas had unsatisfactory hygiene. A total of 1,566 holding samples were taken and 425 samples were sent to the laboratory for analysis. Forty-six of the samples analysed were found to be positive for pathogenic bacteria such as e. coli, staphylococcus aureus and salmonella.
Conclusion : The health personnel from the Johor Health Department in various districts carried out an excellent job in ensuring food safety during the floods. There were no outbreaks of food poisoning. However analysis of food samples taken during the floods did show the presence of pathogenic organisms but probably their numbers were not high enough to cause any food poisoning. The promotion and enforcement of food hygiene requirements should be carried out continuously to ensure that every individual understands the need for hygiene and food safety during disaster situation such as flood.

Food poisoning is still a major problem in the state of Terengganu. The study was conducted during an episode of food poisoning outbreak which occurred in October, 1999, at Universiti Tekonologi Mara (UiTJ1rO, Dungun to determine the etiology, mode of transmission, source and the risk factors of the outbreak and hence to take appropriate remedial actions and preventive measures. A retrospective cohort study was conducted amongst 925 students using a standard questionnaire as well as environmental investigation and bacterial subtyping. All the samples were Malay females, age ranging jrom /9 — 22 years. It was found that majority ofthe victims (72 %) presented with abdominal cramp, 68.5% headache, 60.0% diarrhea, 55.2% fever, 45.0% nausea, 39.0% muscle
ache and 3]. 7% vomiting. The epidemic curve suggested of a common source of infection and the most probable food that has been contaminated was taken during lunch hour on October 20'I'1999, Statistical analysis showed that spices jiied chicken and "nasi minyak" were significantly associated with the illness (p < 0. 05). The most likely causative organism was Salmonella spp as supported by the clinical presentation and incubation period of the disease, identdication of contaminated food, bacterial subtyping result and environmental findings. Following the outbreaks, several remedial actions were taken including immediate close—up ofthe canteen for I4 days, treatment for the cases and health examination and typhoid immunization for all food handlers.
