    A rare case of spontaneous rupture of a branch of the uterine vein in a primigravida is discussed. The patient with an uncomplicated pregnancy presented with signs and symptoms suggestive of abruptio placenta with foetal distress. Lower segment Caesarean section was performed. The cause of acute pain was identified to be intra-abdominal bleeding secondary to the rupture of a branch of the uterine vein. The pathophysiology of the problem is discussed.

    Three East Timorese immigrants presented with signs and symptoms of heart failure in early December 1992. One of them also had features of peripheral neuropathy. Another collapsed within 24 hours of admission and attempts at resuscitation failed. The other two showed dramatic response to oral thiamine therapy. An investigation into their dietary history established gross deficiency in fresh vegetables.

    The intraoperative localisation of small intestinal bleeding lesions identified at pre-operative angiography has always been difficult, resulting in extensive resections in doubtful cases. We report two patients in whom, at angiography, a small intestinal lesion was noted to be the cause of gastrointestinal haemorrhage. They then underwent superselective mesenteric arterial cannulation at a second angiographic procedure and were operated upon with the angiographic catheter left within the branch responsible for the bleeding. This superselective catheter placement facilitates precise localisation of the bleeding site intraoperatively, enabling limited segmental resection of bowel. Both patients have had no recurrent bleeding episodes.

    Developmental and morphological characteristics of 3 isolates of Taenia taeniaeformis isolated from Clethrionomys rufocanus bedfordiae in Abuta (70 km southwest of Sapporo), Japan (isolate ACR), and from Rattus norvegicus in Sapporo, Japan (isolate SRN) and Kuala Lumpur, Malaysia (isolate KRN) were compared. Eggs of 3 isolates were administered to several species of rodents. Isolate ACR infected C. rufocanus bedfordiae, Apodemus speciosus, and Apodemus argenteus, but not rats or mice, whereas isolate SRN and isolate KRN were infective to rats, mice, A. speciosus, and A. argenteus, but not to C. rufocanus bedfordiae. The increase in cyst size of isolate ACR continued during the experimental period, whereas that of the other 2 isolates had ceased growing after 30 days postinfection. However, significant differences were observed in the length of the small rostellar hooks, number and distribution of testes, and the length of the cirrus sac between isolate ACR and the other 2 isolates. Thus it is suggested that isolate ACR is a distinct strain or even a new species.

    Thirty-seven cases of latah are examined within the author's Malay extended family (N = 115). Based on ethnographic data collected and a literature review, cases are readily divisible into two broad categories: habitual (N = 33) and performance (N = 4). The first form represents an infrequent, culturally conditioned habit that is occasionally used as a learned coping strategy in the form of a cathartic stress response to sudden startle with limited secondary benefits (i.e., exhibiting brief verbal obscenity with impunity). In this sense, it is identical to Western swearing. Performers are engaged in conscious, ritualized social gain through the purported exploitation of a neurophysiological potential. The latter process is essentially irrelevant, akin to sneezing or yawning. It is concluded that latah is a social construction of Western-trained universalist scientists. The concept of malingering and fraud in anthropology is critically discussed.

    Isolation of Japanese encephalitis virus (JEV) from mosquitoes in Sabak Bernam, Selangor, Malaysia, was attempted. An aliquot of homogenate from each pool of mosquitoes, 50 per tube, was inoculated into Aedes albopictus clone C6/36 cells for virus isolation. Each cell culture was tested for the presence of viral antigen by immunoperoxidase staining using an anti-JEV polyclonal antibody. Out of 4 Culex sitiens mosquito pools, 2 pools were positive for JEV by cell culture. Presence of JEV genome in the cell cultures for Cx. sitiens was confirmed by using reverse transcriptase-polymerase chain reaction and JEV-specific primers. This is the first report on the isolation of JEV from Cx. sitiens.

    This note reports the experience of an attempt to find and re-interview in late 1988 and early 1989, as part of the Second Malaysian Family Life Survey (MFLS-2), the female respondents to the 1976-77 Malaysian Family Life Survey (MFLS-1) and a sample of their adult children aged 18 or older.... We discuss the field methods used to track the panel members and their adult children, report follow-up rates and analyze the selectivity of attrition from the panel, using data from the MFLS-1 on characteristics of both the missing and the re-interviewed respondents and their families. We then discuss the degree to which these results might be generalized to other such attempts at re-contacting survey respondents.

    PIP: Data from 297 interviews among married patients attending prenatal clinics in Malaysia in 1993 are used to determine the number, spacing, and timing of pregnancies. Only live born children are included. Findings indicate that 92.2% of women were 18-35 years old, 4.2% were under 18 years of age, and 3.6% were over 35 years old. 86.2% had 4 or fewer children and 13.8% had 4 or more children. 69.7% spaced children 2 or more years apart and 30.3% had birth spacing of under 2 years. Over 90% of women had their pregnancies during the ages of 18 and 35 years.

    PIP: To identify the maternal risk factors associated with low birth weight in Malaysia, the records of the 2613 infants delivered at North Okkalapa General Hospital from January to September 1990 were reviewed. The incidence of low birth weight during the 9-month study period was 21.1%; 18.1% of these cases were attributable to intrauterine growth retardation and 3% were associated with preterm births. Univariate analysis identified the following risk factors as significant: age under 20 years (.001), parity 1 (.001), maternal height of 145 cm or under (.01), maternal cigarette smoking (.01), maternal education of 8 years or less (.001), parity 5 or above (.05), and maternal age of 35 years and above (.05). A last birth interval of 1 year or less and more than 3 years was associated with an odds ratio exceeding 1, but the correlation with low birth weight was not significant. These risk factors should be used to design maternal health programs aimed at reducing the incidence of low birth weight.

    PIP: Marvelon, a monophasic oral contraceptive (OC) containing 30 mcg of ethinyl estradiol and 150 mcg of desogestrel, has been available to Malaysian women through the national family planning program since 1982. To assess the safety, effectiveness, and side effects associated with this OC, 247 women who requested the pill were enrolled in a multicenter prospective study that included follow-up after the first, third, and sixth cycles of use. 81% of participants had never used any form of contraception before Marvelon. 194 women (79%) completed the 6-month study. There were no pregnancies recorded. Although women reported a slightly increased incidence of nausea, breast tenderness, and headache in the first treatment cycle, these side effects had abated by the end of the third cycle. After six cycles, mean body weight had decreased by an average of 0.4 kg. Both systolic and diastolic blood pressure were unaffected. An unexpected finding was a decrease in the severity of acne with continuous use of Marvelon. Although both spotting and breakthrough bleeding increased slightly in the first two cycles, irregular bleeding returned to pretreatment levels by the third cycle. The length of the withdrawal bleed in the pill-free week was reduced. The incidence of irregular bleeding and other side effects was substantially lower in this sample of Malaysian women than in Asian and Caucasian Marvelon users surveyed in other studies.

    Chronic hepatitis B virus (HBV) infection constitutes a major public health problem particularly in developing countries in East Asia, South-East Asia, the Pacific Basin and Africa. In Malaysia, a developing nation in the South East Asian region, the chronic HBV carrier rate varies between < 1% to about 10% depending on the ethnic group studied. The highest frequency is seen among the Chinese, followed by the Malays and lastly the Indians, with a male preponderance of between 2 : 1 and 3 : 1. Exposure to the virus among the adult population is estimated to be about 15%, 26% and 36% among the Indians, Malays and Chinese respectively. Serological study of adult chronic HBV carriers showed a frequency of HBe antigenemia of about 35%, with a significant decreasing trend with age. HBV DNA status generally correlated with the HBe status. An atypical profile of anti-HBe associated with serum HBV DNA is found in some carriers; in most instances, this is related to seroconversion from HBe antigenemia to anti-HBe. Chronic complications of HBV infection include the development of hepatocellular carcinoma (HCC), the occurrence of which closely parallel that of HBsAg carrier rate. In Malaysia, HCC is the third most common malignant neoplasm and among the 10 leading causes of death. About 80% of our HCC cases are HBV associated. All 3 ethnic groups are afflicted, the highest frequency being among the Chinese. Males show a disproportionate risk with an odds ratio of 3.93 (p < 0.0001).

    Leprosy is a chronic infectious disease and is still a public health problem in Malaysia. In 1926, the Leper Enactment Act was established which required compulsory notification and isolation of leprosy patients. As a result, the National Leprosy Control Centre (NLCC) was built in Sungai Buloh, Selangor. In 1969, the National Leprosy Control programme was launched with the objective of early case finding and decentralisation of treatment of leprosy. The treatment of leprosy patients is integrated with basic Medical and Health services in Malaysia. With the implementation of multiple drug therapy in 1985, the National prevalence rate of leprosy has reduced from 5.7 per 10,000 in 1983 to 1.7 per 10,000 in 1992. The Research Unit in NLCC was established in 1950, where cultivation of Mycobacterium leprae using mouse foot-pad technique is done. This technique is used for assessment of efficacy of chemotherapeutic agents in leprosy. Research activites are also done in collaboration with the Institute for Medical Research in Kuala Lumpur such as isolation of Mycobacterium leprae antigen using T cell clones and phenolic glycolipid antigen.

    Congo red screening of routine biopsies at the University Hospital Kuala Lumpur revealed the following categories of amyloidosis: systemic AL (5.9%); systemic AA (3.2%); isolated atrial (14%); primary localized cutaneous (7.5%); other primary localized deposits (3.2%); localized intratumour (58%); and dystrophic (8.6%). Unlike in the West, AA amyloidosis in this population was usually secondary to leprosy or tuberculosis. Liver involvement in AL amyloidosis was shown to exhibit a sinusoidal pattern and differed from the vascular pattern of AA amyloidosis. Within the category of AA amyloidosis, there were two patterns of renal involvement--glomerular and vascular, with the glomerular pattern carrying a more ominous clinical picture. Notable among the localized amyloidoses were isolated atrial amyloidosis complicating chronic rheumatic heart disease, intratumour amyloidosis within nasopharyngeal carcinomas and dystrophic amyloidosis which occurred in fibrotic tissues.

    The surge of information on the aetiological association of the human papillomavirus (HPV) with some epithelial tumours emanating from various centres has prompted the initiation of a large-scale retrospective study at the Department of Pathology, University Hospital Kuala Lumpur to determine the prevalence and importance of this virus in some epithelial tumours of Malaysian patients. A retrospective analysis of 100 cases of large cell non-keratinising carcinoma of the uterine cervix by in-situ hybridisation on archival formalin-fixed, paraffin-embedded tissue has revealed the presence of HPV type 16 in 47% and type 18 in 41% of cases. This gives an overall detection rate of 88% of the two HPV types most commonly encountered in cervical carcinomas. Except for the unusually high frequency of HPV 18 detected in the cases, the overall prevalence is comparable to that reported in studies from most other centres. Although this higher frequency of HPV 18 may be due to geographical variation, the selection of the large cell non-keratinising type of squamous cell cervical carcinoma for study remains a possible reason for this phenomenon. In comparison to cervical carcinomas, HPV appears to be uncommon in penile carcinomas and HPV 6 was detected in only 1 of 23 cases studied.

    An analysis of 1000 consecutive, adequate renal biopsies from patients of the University Hospital Kuala Lumpur between 1982 and 1991 revealed: minimal change nephritis (20.7%), focal glomerulosclerosis (2.9%), proliferative glomerulonephritides (16.0%), membranous glomerulonephritis (5.5%), IgA nephropathy (18.5%), lupus nephritis (24.9%), end stage nephropathy (3.1%) and others (8.4%). Compared with the previous decade, IgA nephropathy has emerged as a common entity. Lupus nephritis forms the largest diagnostic entity and is probably related to the selected referral of SLE patients to this hospital.

    In Malaysia, alpha-thalassaemia, beta-thalassaemia, haemoglobin (Hb) E, deltabeta-thalassaemia and Hb Constant Spring are prevalent. It has been estimated that 1 in 4 persons carries one of the above genetic abnormalities. In clinical practice, the major problems are: Hb Bart's hydrops fetalis (homozygous alpha(o)thalassaemia), homozygous 3(o)-thalassaemia, E-alpha thalassaemia and HbH disease. The laboratory procedures for diagnosis are standardised and the molecular basis of most of these genetic abnormalities are characterised. Thus it is possible to formulate a strategy for the detection and prevention of these disorders. The steps include the setting-up of population screening and genetic counselling service for the affected individuals, Society of Thalassaemias for public education and group support, and prenatal diagnosis with selective abortion of affected pregnancies. We embarked on such a programme between 1988 and 1992 in Kuala Lumpur General Hospital and hope to kindle similar effort in other state hospitals.

    A detailed cytomorphologic study was done on fine needle aspiration smears from 651 benign breast lumps. Cytological categorization enabled the distinction of proliferative from non-proliferative and infective lesions in the majority of the cases. Lumpectomy provided the histological diagnosis in 584 cases, most of which were proliferative lesions. Gross cystic disease and fibroadenoma were the most common lesions encountered. Microcysts with apocrine change, sclerosing adenosis, proliferative disease without atypia, atypical ductal hyperplasia, atypical lobular hyperplasia, and lobular carcinoma in situ were associated with the dominant lesion in many of the cases. In all these cases, retrospective analysis of the cytological smears was done in an attempt to identify cytological features which may indicate these lesions.

    Mucins are produced by both benign and malignant gastric epithelium. In general, mucins can be classified into neutral and acidic mucins. The latter are of 2 major types, sulphated (sulphomucins) and carboxylated (sialomucins). A retrospective study was initiated at the Department of Pathology, University Hospital, Kuala Lumpur to histochemically study the mucin profiles of cases of intestinal (IGC) and diffuse (DGC) types of gastric carcinoma in Malaysian patients to determine whether a significant change of mucin type occurs in the event of malignant transformation. 42 IGC and 37 DGC were subjected to alcian blue-periodic acid Schiff and high iron diamine-alcian blue histochemical staining. In addition, 18 cases of gastrectomies performed for benign lesions in the stomach served as normal controls. The number of cases of IGC and DGC which exhibited sulphomucin production was significantly increased (p < 0.001) compared to normal controls. Also, the number of cases of DGC which produced neutral mucin were significantly less (p < 0.05) than the control group. However, there was no significant difference between the number of IGC and DGC cases which demonstrated sialomucin production and normal controls. It appears that while not pathognomonic, a lack of neutral mucin production should alert the pathologist to the possibility of a gastric malignancy, in particular DGC. The likelihood of a malignant lesion would be further supported if there is an increased sulphomucin production.
