The strong international demand for admission into medical schools make medical education a "seller's market", and increasingly a global market. Teaching of Otorhinolaryngology-Head and Neck Surgery (ORL-HNS) has two primary goals. Firstly, a firm grasp of basic principles, recognition and treatment of common disorders, initial management of ORL-HNS emergencies and indications for specialist referral. Secondly, to provide sufficient exposure to the specialty to assist in career planning. Good communicative skills for optimal patient care are essential in the selection criteria of medical students. Proficiency in English is essential to obtain a disproportion share of opportunities in the new economy. The examination evaluation needs to be standardized between the various medical schools and the recommended lecturer-student ratio is maintained. The Joint National Evaluating Board has a very essential role to play in the maintenance of medical educational standards in Malaysia.
This paper outlines issues related to curricular reforms, and strategies to be considered for planning and implementation so as to ensure that the change is institutionalised. In Malaysia, in general, some imminent curricular changes have been carried out to prepare graduates for future changes in the practice environment. Change of reform requires planning, with consideration of the directions in which the change is needed, and the possible educational approaches to be utilized. To ensure change can occur and be maintained there should be effort to induce a paradigm shift amongst teachers and administrators at all levels, there must be transparency and dissemination of information of the required change and why, there must be involvement of teachers in decision making to ensure better compliance.
Plumbagin, isoshinanolone, epishinanolone, shinanolone, quercetin and kaempferol were isolated from the leaves of Nepenthes gracilis. Spectral data of shinanolone are presented.
A total of 676 palpable breast lumps seen in the Breast Clinic, University Hospital, Kuala Lumpur from August 1993 to August 1994 were subjected to fine needle aspiration cytology. Fifty-four were reported as inadequate, 501 benign, 95 malignant and 26 suspicious. One hundred and eighty-seven aspirates had histological correlation, while 34 of the malignant aspirates had clinical correlation. The majority of the other 455 patients were followed up for a period of 60 to 72 months without any malignancies becoming apparent. For analysis, only the 221 cases with histological or clinical correlation were included, (the suspicious category was included into the positive group and the inadequate cases were excluded), giving a sensitivity of 91.7%, a specificity of 91.7% and a diagnostic accuracy of 91.7%. Breast cytology was an accurate and rapid method of diagnosis of breast diseases, and in a busy surgical unit with limited operating time, it allowed for the triage of patients with breast complaints in deciding which cases needed early open biopsy. A negative cytology does not exclude the possibility of cancer, as there was a false negative rate of 11%. However by utilising a diagnostic triad of clinical examination, radiological assessment and fine needle aspiration cytology, the risk of missing a malignancy is small.
The method of backcalculation estimates past HIV infection rates from available AIDS incidence data and an estimate of the incubation period. The method is used on the Malaysian data to model the AIDS epidemic because it makes use of the Malaysian AIDS incidence data which is fairly reliable and is more reflective of the trend of the epidemic as compared to the HIV infection rate recorded. An application is made on the monthly AIDS incidence data in Malaysia from January 1995 until August 1996 released by the Ministry of Health, Malaysia using the backcalculation program from Bacchetti et al and the incubation period distribution from Brookmeyer to generate the current HIV infection rate for Malaysia (until August 1996).
A survey of specialisation choices was conducted for two batches of medical officers applying to the local medical schools for specialisation in Malaysia. A total of 359 doctors responded, giving a response rate of 71%, with 169 male (44.4%) and 187 female (55.6%) respondents. Surgery ranked highest among the male doctors followed by orthopaedic surgery and internal medicine. Family medicine ranked highest among female doctors followed by public health and anaesthesiology. Among the other specialties, the male doctors preferred otorhinolaryngology while female doctors preferred Pathology. Both male and female doctors chose to be a clinical consultant in a general hospital as the first choice. They prefer to work in or near their hometowns.
Globally, abortion mortality accounts for approximately 13% of all maternal mortality. Unsafe abortion procedures, untrained abortion providers, restrictive abortion laws and high maternal mortality and morbidity from abortion tend to occur together. Unplanned and unwanted pregnancies constitute a serious public health responsibility. While fertility has declined by half in developing countries, the motivation to control and space births has risen faster than the rate of contraceptive use. Preventing maternal mortality and morbidity from abortion in countries where these remain high is a matter of good public health policy and medical practice, and constitutes an important part of safe motherhood initiatives. A range of positive steps has been taken to reduce deaths and morbidity from abortion in a growing number of countries over the past 15 years. Making abortion legal is an essential prerequisite in making it safe. In this respect, changing the law does matter and assertions to the contrary are ill conceived and unsupported in practice. Although, in many countries, trends towards safer abortion have often occurred prior to or in the absence of changes in the law, legal changes need to take place if safety is to be sustained for all women. Religious laws may also require attention when legal change is being contemplated. There are three main ways of approaching this problem: liberalizing the existing law within the penal or criminal code; partially or fully legalizing abortion through a positive law or a court ruling; and decriminalising abortion by taking it out of the law. Women's health groups and other advocates, parliamentarians and health professionals, can work together to support the right of women not to die from unsafe abortions and to ensure they receive treatment for complications. Committed doctors can make a difference by providing treatment for abortion complications, interpreting the law in a liberal way and providing safe services where these are legal as well as training providers in the safest techniques to reduce mortality and morbidity. Although law, policy and women's rights are central to this issue, making abortions safe is above all a public health responsibility of governments. Moreover, reducing maternal mortality by making abortions safe is also an important part of the international commitment made in Cairo in 1994 at the ICPD and reaffirmed at the Cairo meeting in 1999.
Armillaria root rot is a serious disease, chiefly of woody plants, caused by many species of Armillaria that occur in temperate, tropical and subtropical regions of the world. Very little is known about Armillaria in South America and Southeast Asia, although Armillaria root rot is well known in these areas. In this study, we consider previously unidentified isolates collected from trees with symptoms of Armillaria root rot in Chile, Indonesia and Malaysia. In addition, isolates from basidiocarps resembling A. novae-zelandiae and A. limonea, originating from Chile and Argentina, respectively, were included in this study because their true identity has been uncertain. All isolates in this study were compared, based on their similarity in ITS sequences with previously sequenced Armillaria species, and their phylogenetic relationship with species from the Southern Hemisphere was considered. ITS sequence data for Armillaria also were compared with those available at GenBank. Parsimony and distance analyses were conducted to determine the phylogenetic relationships between the unknown isolates and the species that showed high ITS sequence similarity. In addition, IGS-1 sequence data were obtained for some of the species to validate the trees obtained from the ITS data set. Results of this study showed that the ITS sequences of the isolates obtained from basidiocarps resembling A. novae-zelandiae are most similar to those for this species. ITS sequences for isolates from Indonesia and Malaysia had the highest similarity to A. novae-zelandiae but were phylogenetically separated from this species. Isolates from Chile, for which basidiocarps were not found, were similar in their ITS and IGS-1 sequences to the isolate from Argentina that resembled A. limonea. These isolates, however, had the highest ITS and IGS-1 sequence similarity to authentic isolates of A. luteobubalina and were phylogenetically more closely related to this species than to A. limonea.
Malaysia plays the leading role in homeopathy in Southeast Asia. The history of homeopathy in the Malay civilization began in the 1930s. Since then, it has been practiced mainly by Malays who are all Muslims. Homeopathy in multiethnic Malaysia is embedded in Islamic culture and has to do with ethnic identity of the Malays within the Malay/non-Malay dichotomy of the society. This survey explores the relationships between homeopathy and Malay traditional medicine, as well as between homeopathy and Islam.
The number of women in the workforce in increasing. A substantial proportion are in the reproductive age which brings to attention the problem of work exposures that adversely affect reproductive outcome. These exposures include chemicals, radiation, strenuous physical activity and infections. They affect reproduction by effect on the germ cells, through hormonal distribution which in turn affects transport of germ cells or zygote, implantation and development. Some of these exposures are teratogenic. At present, some regulations and policies seem to be directed at women workers while there is evidence to show that women are not the only victims. Paternal exposures have also been reported to be associated with infertility, spontaneous abortions and other adverse outcomes. There is insufficient information about reproductive effects of work exposures and hence further research is required in this area.
Pollen flow and population genetic structure among 30 potentially flowering individuals of Neobalanocarpus heimii, a tropical emergent tree, were investigated in a lowland tropical rainforest of Malaysia using microsatellite polymorphism. The 248 offspring in the vicinity of five reproductive trees of the 30 potentially flowering trees were used in paternity analysis for pollen-flow study. Four primer pairs, developed in different species of dipterocarps, were adopted to detect microsatellite polymorphism. Based upon microsatellite polymorphism, pollen flow and seed migration were detected. Pollen-flow events of more than 400 m were observed directly, based on paternity analysis in the study plot. The estimated average mating distance of the five reproductive trees was 524 m. This result suggests that reproduction of this species is mediated by a long-distance pollinator. The haplotypes of some offspring were not compatible with the nearest reproductive tree. Thus, the results suggest that some seeds are dispersed by a seed dispersal vector. Investigation of genetic structure showed significant and negative correlation of genetic relatedness and spatial distances between the 30 potentially flowering trees, but this correlation was weak. We suggest that long-distance gene flow and seed migration are responsible for the poorly developed genetic structure of this species.
Adequacy of active resuscitation in collapsed inpatients aged 12 and above (excluding those with terminal illness) were studied in 6 Malaysian district hospitals for 3 months starting 1/1/93. Results showed 59.5% (25 out of 42 inpatients) were inadequately resuscitated measured by: failure of nurses to initiate resuscitation (24%), duration of resuscitation less than 30 minutes (42%) and incompletely equipped emergency trolleys (44%). Questionnaires revealed lack of knowledge and training in cardiopulmonary resuscitation in medical staff. Regular cardiopulmonary resuscitation courses, regular spot checks on emergency trolleys and management protocols on active resuscitation are recommended. Each hospital should design its own criteria for adequacy.
Fully mapped tree census plots of large area, 25 to 52 hectares, have now been completed at six different sites in tropical forests, including dry deciduous to wet evergreen forest on two continents. One of the main goals of these plots has been to evaluate spatial patterns in tropical tree populations. Here the degree of aggregation in the distribution of 1768 tree species is examined based on the average density of conspecific trees in circular neighborhoods around each tree. When all individuals larger than 1 centimeter in stem diameter were included, nearly every species was more aggregated than a random distribution. Considering only larger trees (>/= 10 centimeters in diameter), the pattern persisted, with most species being more aggregated than random. Rare species were more aggregated than common species. All six forests were very similar in all the particulars of these results.
We report a case of leptospirosis infected in Sabah, Borneo island, Malaysia. The case is 25-year-old male who had participated in the EcoChallenge Sabah 2000 Expedition Race, a multisport event held during August 20 to September 3, 2000 at various sites in Sabah in Malaysian Borneo. He developed a high fever and headache on September 7, and he was admitted to our hospital on September 9. On admission he also had conjunctivitis and myalgias. Laboratory findings on admission revealed leukocytosis with left shift, slightly elevated transaminase levels, high CRP levels and proteinuria. Plasmodium spp. were negative on blood smears, and no bacteria were isolated from blood and feces cultures. We performed the laboratory tests for leptospirosis, based on the information about the probable leptospirosis outbreak among athletes who participated in the EcoChallenge Race, however both Leptospira antigens and antibodies were negative at that time. We diagnosed leptospirosis clinically because he manifested persistent symptoms, and minocycline 100 mg b.i.d. was administered intravenously resulting in excellent efficacy. Serum antibody tests by microscopic agglutination test (MAT) at convalescent stage revealed significant increased antibodies against Leptospira interrogans serovar hebdomadis, and the diagnosis of leptospirosis was confirmed. Infectious diseases have been global and it is important to have information concerning worldwide infectious disease situations as much as possible for accurate diagnosis.
