Two cases of Syndromes of Ophthalmoplegia , Ataxia and Areflexia were reported. A brief discussion on its clinical feature and differential diagnosis was made.
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.
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.
Changing social demands made it necessary for the Medical Faculty of the University of Malaya to accommodate students with a wider range of academic experience than before. However, teachers sought to achieve comparable academic standards to those in the West by striving to maintain a close resemblance to the Western model of medical education in other respects. As a result teachers failed to adapt their teaching methods, assessment techniques and curriculum design to meet the educational needs of the students, thus compromising academic standards. Many students lack basic academic skills and do not know how to learn effectively. In order to help students overcome their learning difficulties innovative teaching was required during the first year at university, designed to foster the joint development of knowledge and basic skills. In the case of less well-prepared students who lack self-confidence, a caring and supportive learning environment is crucial to the achievement of meaningful learning. Lecturers needed to become facilitators of learning rather than transmitters of knowledge. However, teachers' objective to retain international recognition of the degree, which presumably reflected the importance of teaching, was not operationalized in terms of its incentive structure such that teachers were constrained not to try to fill the new roles demanded of them. It was assumed that academic distinction accrued through scientific research was essential for the achievement of academic excellence. However, under the prevailing circumstances the two aims were mutually exclusive and incompatible and teaching quality deteriorated.
Nurses are an integral component of the health care delivery system. In discharging their duties, nurses encounter a variety of occupational health problems which may be categorized into biological hazards, chemical hazards, physical hazards, and psychosocial hazards. A review of some examples of each of these four types of hazards is presented in this article. Particular attention has been devoted to hepatitis B, acquired immunodeficiency syndrome, tuberculosis, cytotoxic drugs, anesthetic agents, needlestick injury, back pain, and stress.
Fifty-four per cent of 52 patients presenting to the University of Malaya Medical Centre with a myelopathy for which appropriate investigations uncovered no definite etiology, subsequently developed clinically definite or probable multiple sclerosis. In the subgroup of patients with a presentation indicative of acute/subacute transverse myelopathy, 14 or 52% also went on to develop clinically definite or probable multiple sclerosis, a far higher proportion than previously recorded in the literature. This finding is probably a further manifestation of racial difference in the behaviour of multiple sclerosis. For the group as a whole, the only factor which appeared to be associated with an increased risk of developing multiple sclerosis was female sex; 67% of 33 female patients went on to develop multiple sclerosis after a mean follow-up period of 5.5 years. Other factors such as age of onset, racial composition, level of spinal cord involvement, presence of fever and CSF finding were found not to be important.
Perinatal mortality rates have been gradually declining in all countries. The initial decline mainly resulted from improvements in the late foetal mortality rates. Later with improvements in neonatal care, early neonatal mortality rates also improved. The developed countries have consistently shown better results than the developing countries, an indication of the higher standard of living, general health as well as the delivery of health care in these countries. In the Singapore situation, a rapid improvement in perinatal mortality was initially observed due to improvements in the late foetal mortality, followed later by reduction in the early neonatal mortality due to upgrading of neonatal intensive care. The perinatal mortality rate is lowest in the Chinese compared to the Indians and Malays, most likely due to the dietary practices of the three ethnic groups in Singapore; while the Chinese encourage extra nutrition in the pregnant female, the Malays and Indians tend to practise dietary restriction during this period. The improved nutrition of the pregnant mother is a factor in improving the perinatal mortality.
3 cases of perforating injury with retention of intra-ocular foreign body are presented. Their clinical presentation, management and final visual results are discussed. Despite the generally poor prognosis associated with these injuries, some cases surprisingly have good visual results.
The reasons why 860 patients visited the general medical clinic at the University Hospital, Kuala Lumpur were studied. 75.3% of the patients came for evaluation of symptoms; 12.4% sought checkups for chronic diseases; 4.9% requested diagnostic checkups and screening tests; 4.8% came to renew prescription. Few visits were made for evaluation of injuries, receiving test results or for administrative examination. This profile reflected the function of the clinic as an acute diagnostic centre. Other applications of the results are discussed.

A total of 23 patients with psychoses associated with thyrotoxicosis were admitted to the psychiatric unit of a University Hospital over a 13-year period, of which 20 patients were included in this retrospective study. It was found that a parallel relationship between thyrotoxicosis and psychosis appears to exist in six patients, while in the remaining 14 patients, the course of the two disease processes were largely independent of each other. Paranoid delusions and auditory hallucinations were the most prominent psychiatric symptoms. Depression was commonly seen even in patients who were not having an affective illness. In four patients, a mixed schizo-affective psychosis was seen, suggesting that the diagnostic distinction between the affective and schizophrenic reactions are often blurred in psychosis associated with thyrotoxicosis.
Thirty four patients with cryptococcal meningitis seen in the University of Malaya medical centre since 1980 were reviewed. Eleven patients had bilateral papilloedema and visual impairment but eventually survived. Seven patients had intensive aggressive measures, including shunting to reduce intracranial hypertension irrespective of ventricular size shown in CT scan, and showed substantial improvement in vision. It is concluded that papilloedema and visual failure in cryptococcal meningitis reflects raised intracranial pressure and that this should be treated vigorously.
Following revision of the curriculum the effectiveness of a traditional cookbook experiment, used in conjunction with an 'interpretation seminar', was evaluated. Curriculum revision had been predominantly concerned with an avoidance of overloading and provision of self-study periods. The preceding lectures were integrated with the experiment. The learning resulting from the practical experience was assessed using pre- and post-tests. The practical exercise was ineffective and did not facilitate conceptual understanding. Due to the central role of passive teaching methods the students adopted a surface approach to all learning, were teacher dependent and did not make effective use of their private study. Furthermore, owing to a broad-based entry into medical school many students lacked the basic skills essential to the achievement of meaningful learning. Clearly, for effective learning the curriculum and pedagogy must be geared to the background and educational needs of the students.
Epidemiological studies of human leptospirosis have generally been limited to countries with specialized laboratories employing the microscopic-agglutination (MA) test. The sensitized-erythrocyte-lysis (SEL) test is much simpler for routine hospital laboratories to carry out and it has been found valuable in the diagnosis of human leptospirosis. This paper reports the results of studies of the SEL test as an epidemiological tool in serological surveys.The results showed that the significant SEL titre was 1:80 and that the sensitivity of the test depended possibly on the antigen preparation and the amount of complement used. Most of the SEL antibodies were found to persist at significant titres for about 1 year after active infection, but less than half persisted longer than that. The SEL test is therefore useful for detecting recent infections and for indicating that stability of leptospirosis in an area.The endemicity of leptospirosis in West Malaysia was confirmed by the SEL test, based on the employment of 1:80 as the significant titre.
