A total of 104 marine fish belonging to 12 species in 6 families were examined for anisakid larvae. All except one fish species were infected with one or more types of anisakid larvae. Three types of anisakid larvae were recovered, the most abundant being Anisakis type 1 (9 out of 11 fish species) followed by Contracaecum type B (6 out of 11) and Terranova type B (1 out of 11). Latianus malabaricus has the highest mean intensity of both Anisakis type 1 and Contracaecum type B. The public health hazard of anisakine nematodes is briefly discussed.
Comparative studies of vector efficiency were done with the Liverpool and Malaysian strains of Aedes (Finlaya) togoi for subperiodic Brugia malayi and Brugia pahangi. The Malaysian strain of A. togoi was found to take in fewer microfilariae under the same experimental conditions than the Liverpool strain. Also, for various microfilarial densities in the host's peripheral blood, the Malaysian strain had less mean infective larvae per fed mosquito than the Liverpool strain. The microfilarial intake of A. togoi was not affected by the site of feeding on the host affected by the site of feeding on the host. Most of the mosquitoes took in fewer microfilariae than expected. It is concluded from these studies that the Malaysian strain of A. togoi is a susceptible and reasonably good vector for subperiodic B. malayi and B. pahangi. Further field studies should be carried out to determine its importance as a natural vector of Brugian filariasis.
A report of 25 cases of neurosyphilis seen in University Hospital, Kuala Lumpur since 1970. Classical form of the disease still constitute the majority of the patients with often long delay before diagnosis.
The results of the food consumption study suggested that the calorie and protein intakes of ID and 20 malnourished preschool children in the study area were much lower than the RDA and thus these children should benefit from a supplementary feeding project. However, after 42 days of supplementation with Nutri-Pak, the project's objective of increasing by 5%, the percent standard weight for age of at least 60% of the subjects was not achieved since only one child's weight reached this target. From the records of monitoring, it was noticed that the low consumption of Nutri -Pak. a partial replacement by the the food supplement of the children's diet in the home. uncooperative mothers, and illness or disease factors had contributed to the much lower weight gains than expected in most of the children.
Serum ferritin concentration has been measured in pregnant women at their first antenatal visit. Results were analysed according to trimesters. With progression of the pregnancy there is a fall in serum ferritin concentrations. Haemoglobin and red cell indices cannot be used to predict iron status supplemental iron therapy raised the serum ferritin levels.
An Indian family with four members having hereditary ataxia was presented. The inheritance was most likely autosomal dominant. The onset was at adult life. The main disability was cerebellar ataxia with pyramidal tract sign found at physical examination. Electroencephalography and nerve conduction study were abnormal in two cases where they were done. The clinical feature correspond to an intermediate form of hereditary ataxia.
A 17 year old male with ataxia telangiectasia [Louis-Bar Syndrome] is presented here with a review of the literature with regards to the mode of inheritance, clinical manifestations, diagnosis and treatment of this disorder.
A retrospective study of 62 cases of myasthenia gravis in Malaysia is reviewed. It shows an apparent prevalence among the ethnic Chinese compared with the Malay and Indian. The incidence of male and female and their average age of onset are similar. Unlike the western figure, among those with age of onset less than 20 years. both sexes are equally affected. The symptomatology, morbidity and mortality and incidence of thymoma are the same as those
reported elsewhere.
A 103 year old patient was admitted with pain in the right iliac fossa. There was no response to conservative treatment. Subsequent laparatomy showed the presence of a perforated ulcer in the pyloric region. The condition improved gradually after the surgical management.
This study was proposed to identify specific radiological appearances in Malaysian patients with bronchial asthma. All consecutive patients, seen in the Medical Unit, Universiti Kebangsaan Malaysia between 1976 and 1979, satisfying the American Thoracic Society [1962] criteria for bronchial asthma formed the subjects of this study. Analysis of 207 patients led to the following conclusion. There are specific radiological changes present in a proportion of bronchial asthmatics during the acute episode. These changes are more frequent in the younger age group and in those in which the age of onset are early, The duration of asthma seems to have some bearing to the radiological changes.
Relatively few cases of myocardial infarction associated with coronary artery atherosclerosis have been described previously in macaques. In this study the authors report the prevalence and characteristics of coronary artery atherosclerosis and myocardial infarction in 10 rhesus (Macaca mulatta) and two cynomolgus (Macaca fascicularis) macaques that were fed atherogenic diets for 16 months or longer. Our findings show clearly that myocardial infarction occurs in macaques with diet-induced atherosclerosis. The frequency seems to be related to the species, composition of the atherogenic diet, and length of time fed the atherogenic diet. The myocardial lesions are remarkably similar to those described in human beings in terms of location and gross and microscopic characteristics. The characteristics of coronary artery atherosclerosis, including the occurrence of thrombosis, severe stenosis, mineralization, atheronecrosis, and sterol clefts, especially in animals fed the atherogenic diets for longer periods of time, also closely resemble those of the arterial lesions found in human beings. The greatest prevalence of myocardial infarcts was found in rhesus monkeys fed a cholesterol-containing diet with 40% of calories supplied by peanut oil and in cynomolgus macaques from Malaya that were fed the same amount of cholesterol with 40% of calories from lard. Electrocardiographic abnormalities as well as the occurrence of unexpected and relatively sudden death in several of these nonhuman primates are also consistent with signs frequently observed in human beings.
We evaluated 3,066 consecutive women admitted during 1 year to two major hospitals of Kuala Lumpur and the adjacent urban area of Malaysia. Indicators of acute pelvic inflammatory disease were more common among patients with induced abortions. PID was thought to be a major contributor to the higher costs associated with management of patients with induced abortions.
