The peculiar anatomical features render the common peroneal nerve particularly susceptible to injury at the knee. The present investigation revealed that the deep division of the nerve is more inclined to be injured when compared to the superficial division.
Two hundred and three patients with psoriasis, who attended the skin clinic were studied to identify the pattern of sporiasis. The incidence was 4%. It was more common in Indians than in the other ethnic groups and this was found to be statistically significant. Males were affected twice as common, 12.5% gave a positive family history, the lower limbs and the scalp were the commonest site, and pruritus was frequent. The pattern appears similar to those in the west.

A case of pseudomyxoma peritonei is reported. Pathogenesis, clinical features and modes of treatment are discussed. This patient appears to have responded to laparotomy, paracentesis and instillation of cyclophosphamide intraperitoneally.
The effects of phentolamine and propranolol on contractural responses of guinea-pig superior mesenteric-portal vein to adrenaline and isoprenaline were investigated. Phentolamine was capable of completely abolishing the response to adrenaline and to isoprenaline while propranolol had no effect on responses to either agonist. It is suggested that Alpha receptors are the only type of adrenoceptor involved in adrenergic control of contraction of this vein and that isoprenaline is capable of stimulating these receptors.
Four strains of S. typhi isolated in Malaysia were found to show resistance to chloramphenicol and other antibiotics. In two of these strains it was possible to show that this resistance was transferable.
This problem which is widespread in neighbouring countries and undetected in Malaysia till recently has now been shown to exist in this country. Fears that the incidence of such strains will increase in the future are expressed and the need for vigilance is emphasised.
Facts are presented which suggest that mosquitoes of the Anopheles barbirostris species group that gave me a very uncomfortable night in 1941, whilst serving with the Volunteer forces, were probably A. donaldi. This species is now known to be a vector of human filariasis and probably malaria. Some of the steps are described by which I was led, sixteen years later, to recognise and later name donaldi as a new species. Reasons are given for thinking that around 1918 A. donaldi was present in some numbers at the railway town of Gemas where malaria was a serious problem. H.P. Hacker made a survey at Gemas in 1918 and though the principal vector was probably A. maculatus, 'umbrosus' and 'barbirostris' were the commonest larvae he found.
In a prospective study of 300 infants with acute gastroenteritis 150 infants had enteropathogens in the stools, 58 being due to rotavirus, 130 to adenovirus, 32 to Sahnonella, 18 Shigella and 29 E. coli. Hypernatraemic dehydration was present in 11% and acquired carbohydrate intolerance in 30% of the infants. Protracted diarrhoea was observed in 8% of infants and was commoner in the bacterial than viral group. The study shows that clinical features and simple blood tests cannot be used as reliable indices of predicting the aetiology of AGE. Despite the diverse aetiology of acute gastroenteritis, rehydration by the oral or intravenous route remained the mainstay of therapy.

A preliminary survey of Aedes aegypti was carried out in 6 areas in the state of Selangor, Malaysia. The densities of Ae. aegypti and Ae. albopictus in the areas were discussed. Results indicated that the distribution of larval habitats varied with the housing type. The most ommon indoor larval habitat in urban areas is the bathroom tank. In both urban and rural areas, outdoor preference is for the earthenware jars. Anttraps have decreased in importance as larvae breeding habitats. The accuracy of house searches can be increased by increasing the number of larvae examined per container to 5 or more. Further study is required to determine whether the findings of this survey is peculiar to the areas surveyed or is representative of the whole country, and whether there is a seasonal fluctuation in the types of preferred larval habitats.
Two Malaysian boys of Chinese origin who satisfy the necessary criteria of subacute sclerosing panencephalitis are reported. A brief description of the symptomatology, epidemiology, laboratory finding, pathology, pathogenesis and treatment of the illness was also given.
The juice of the banana trunk produces a nondepolarising neuromuscular block. Oxygenation of
the extract enhances its potency. Reversal with anticholinesterase is transient. Partial reversals in isolated preparations indicate there could be both specific and non-specific binding which could account for blockade after washing. It could be specifically bound to ACh receptors in an irreversible way. Its action appears similar to that of alpha-BuTX from the venom of the banded krait. Purification of the extract and subsequent investigations will support present findings and present the characteristics fully.
Those Malaysian secondary schoolchildren who have ever used an illicit drug do not differ significantly in terms of social class background, ethnicity or rural/urban location, from the majority of their contemporaries who have not used drugs. The cross-sectional data show a rapid secular trend towards the sexes being equally involved in drug use. Significant differences between ever and never users are, however, found in their attitudes towards drug taking and their beliefs about the properties of drugs, although both groups share the same rather negative image of the typical drug user. Thus, drug users have accepted some of the attitudes towards drug issues which are normative in the non-user group, whilst developing other attitudes which are consistent with their continuing use. It is argued that adolescent drug abuse in Malaysia is not to be linked specifically with social deprivation, but should be seen as being part of the life style of particular groups in all strata of society.
The present paper is the third and concluding part of a study of the secondary school population of two of Malaysia's thirteen states, Penang and Selangor. Since completion of the two earlier papers, the research team has investigated the pattern and nature of drug use among the equivalent population in a third state, Kelantan, and has again found essentially the same pattern of results: youthful drug use is most clearly related to precocious self-assertion, and a set of beliefs and attitudes about drugs and drug taking, and is largely unrelated to indicators of social deprivation or personal problems. The significance of this repeated finding in Kelantan is that, in this much more rural and traditional state, adult and established patterns of drug use had historically differed considerably from those found in the two more urban and cosmopolitan states of Penang and Selangor. Our findings indicate that the new pattern of drug use by youth has transcended the older cultural differences between the states, and is in turn explained by a more universally familiar set of characteristics in adolescent development.
In the first 9 years following the opening of the University Hospital in kuala Lumpur nearly 130,000 patients have been admitted (excluding obstetric patients), and, of these, 175 fulfilled the American Rheumatism Association criteria for the diagnosis of systemic lupus erythematosus. This diagnosis was made significantly more frequently in Chinese patients than in other races. SLE is more often reported from Chinese communities in Asia than from India and tropical Africa. There may be a lower susceptibility to autoimmune disease in black Africans than the suspected increased susceptibility to autoimmune disease in black Africans than the suspected increased susceptibility in their American Negro and West Indian descendants. A careful study of racial and geograhical factors in autoimmune disease should throw further light on the interaction between the host and his environment which results in autoimmune disease.
A breeding colony utilizing a harem mating system was established to study the feasibility of breeding cynomoglus monkeys, Macaca fascicularis, in Malaysia. Two groups consisting of 10 females and one male each were evaluated over a 3 period. Forty births were recorded; one was stillborn, 11 died while nursing, and 28 were weaned. The average time to wean offspring was 230 days with an average weight at weaning of 0.858 kg. The average time for conception to take place after weaning was 50 days. Of the 20 breeder females, six produced three offspring each, nine produced two offspring each, four produced one offspring each and one remained barren throughout the project. Three different weaning systems were evaluated. The best method was caging the mother-infant pair within or adjacent to the breeding room followed by a two-part cage system which allowed the infant to continue nursing and also obtain solid food inaccessible to the mother.
The indirect hemagglutination (IHA) test done with turkey red cells was applied to 173 serum samples obtained from patients and persons exposed to Wuchereria bancrofti and Brugia malayi in endemic areas of Peninsular Malaysia. A crude extract of adult worms of the rat filaria, Breinlia booliati, was used as the antigen. When a titer of 1:16 was taken as negative, positive IHA test rates in sera from microfilaria-negative persons in endemic areas, microfilaremic cases, and patients with clinical filariasis were 13%, 75%, and 80%, respectively. Results of the IHA test correlated well with results obtained with the indirect fluorescent technique.
