This study presents clinical observations in pregnancy made on aborigines of the deep jungle and "outside" populations. Migration out of the jungle results in lowered nutritional status as a result of low socio-economic status in the "outside" aborigine. This, together with food habits, increased family size and higher incidence of helminthic infestations, results in lower mean values of Hb, PVC and MCHC and a higher prevalence of anaemia in pregnancy in the migrant aborigine. A higher population density in the "outside" population resulting in frequent intermingling and increased chances of cross-contamination probably explains the increased vaginal bacterial growth in the "outside" Aborigine women. A higher prevalence of vaginal candidiasis in the "outside" aborigine woman is probably related to exposure to oral contraceptives and broad-spectrum antibiotics. On the other hand, better medical and obstetrical services become more readily available to the "outside" aborigine and this results in a favourable influence on perinatal health.
Infective larvae of Brugia malayi subperiodic obtained by dissection of infected Aedes togoi were injected subcutaneously into the scrotal region of Mastomys natalensis. From altogether 58 infected male M. natalensis 81% showed consistently or intermittently detectable microfilaraemia, whereas in 19% of the animals no microfilaraemia could be detected at any stage. The mean prepatent period was 136 days; the microfilarial density varied from 1 to 535 per 20 c. mm blood. In those animlas with consistently detectable and in general higher microfilaraemia an average of 13.1 live adult worms were found, against an average of 6.4 adult worms in animals with intermittent detectable and in general lower microfilaraemia. An average of 1.5 worms was found in animals which at no stage showed detectable microfilaraemia. A correlation between worm burden and prepatent period could be observed in the individual groups. From the total of 520 live adult worms recovered at necropsy, 37% were found in the lungs, 29% in the parenchyma of the testes and 34% in the lymphatic system. 47% of live fertile female worms were found in the lymphatic system, whereas the majority, i.e; 52% of infertile female worms were detected in the lungs. In addition, 380 encapsulated dead worms were found, most of them (98%) in the lymphatic system. 61% of a total of 900 live and dead worms were found in the region of the lymphatic system.
A description of sensory receptors of Trichobilharzia brevis is given. They are compared with the five Schistosomatidae described by Richard (1971), namely, Trichobilharzia ocellata, schistosoma mansoni, S. bovis, S; haematobium and S. rodhaini. All these species display very similar chaetotaxic characters. In the study of the cercaria of Haplorchis pumilio, comparison with the few Opisthorchioidea cercarial sensory organs already known has enabled the authors to characterise the chaetotaxy for this superfamily.
Angiostrongylus cantonensis Chen, was recovered from a field rat, Rattus tiomanicus from the East Coast of Peninsular Malaysia. The parasite constitutes the first reported record occurring in this country. Morphological character of the parasite are compared with the original description of A. cantonensis by Chen (1935), A. cantonensis from Formosa and A. malaysiensis from Malaysia.
In a study of infant feeding practices in 95 infants aged three months and six months in the rural, predominantly Malay district of Kubang Pasu, which is recently undergoing rapid economic development consequent on the introduction of improved agricultural techniques in rice farming, it was found that approximately 75% of infants in both age groups were wholly or partially breast fed, modified powered milk being the milk food of most of the others. Semisolids were introduced early in the form of commercial prepacked cereals. It is suggested that medical officers of health recognising local socioeconomic and cultural changes that might affect health behavior can initiate simple studies of this type to identify local needs in health education. In circumstances such as this where a still popular beneficial traditional practice like breast feeding might be at risk of losing popularity in the face of socioeconomic development in the community it is suggested that the most useful educational effort regarding infant nutrition would be to preserve breast feeding.

Seroreactivity to syphilis is high among Malaysian blood donors and expectant mothers indicating a high degree of treponemal infection. Further epidemiological studies are required to ascertain what proportion of these could be syphilis and what porportion yaws. Blood donors hava a higher reactivity rate than expectant mothers, the reasons probably being soical. The titres obtained in the VDRL test appear to have a relation to FTA-ABS reactivity although this is not to say treponematosis can be excluded on the basis of low titre VDRL results.
This report is of a man who suffered from chronic melioidosis contracted in Malaysia. In the course of the disease he had a lobe of a lung resected, developed empyema and, while this was still draining, developed infection in an ankle. Both the empyema thoracis and the ankle infection were due to Pseudomonas pseudomallel. He now appears to be cured, probably by massive doses of tetracycline.
The response to lepromin and Kveim antigens was compared and studied in 15 leprosy patients who were tuberculin negative. Of the 11 lepromin positive tuberculoid patients, 4 were Kveim positive, 1 was equivocal, and the rest were negative. Of the four lepromin negative lepromatous patients, one gave a positive Kveim test while the other three were negative. It has been shown that false-positive Kveim reactions are found in a higher percentage of South Indian leprosy patients than in those of other backgrounds, such as Japanese and Malaysian Chinese patients. It is also suggested that no definite relationship exists between the reaction of leprosy patients to lepromin and Kveim antigens. We further suggest that the anergy exhibited by lepromatous patients to the antigen of M. leprae is specific, as evidenced by the positive Kveim response in one lepromatous patient.
PIP: A traditional birth attendant, also known as an indigenous midwife, is the main provider in many developing countries of obstetric services. Due to this unique position, the traditional birth attendant has been considered as possibly the ideal person to deliver family planning services in her local community. This consideration has influenced program policy in many countries and consequently there is information available to aid in the determination of whether to involve traditional birth attendants and, if so, how to best use them. There have been 2 opposing views in response to the involvement of traditional birth attendants. 1 view regards them as potential innovators. She is seen as ideally placed both physically and socially to act as a representative of the family planning program to her patients. The traditional birth attendant is the acknowledged and often prestigous expert on obstetrics matters, including at times traditional methods of birth control. The alternative view is less hopeful for rather than identifying the traditional birth attendant as an innovator it regards her as a firm opponent of innovation, a determined conventionalist. Pro gram experience in India, Pakistan, Indonesia and East Java and experime ntal studies in the Philippines, Malaysia, and Thailand along with anthr opological inquiries generally support the skeptical view but none of the findings imply that the traditional birth attendant should be ignored by the family planning programs. In the intermediate positions of many actual programs, the wisest plan seems to be to ensure that the potential contribution of the traditional birth attendant is neither overlooked nor exaggerated
