"This paper estimates a proportional hazards model for the timing of age at marriage of women in Malaysia. We hypothesize that age at marriage responds significantly to differences in male and female occupations, race, and age. We find considerable empirical support for the relevance of economic variables in determining age at marriage as well as evidence of strong differences in marriage patterns across races."

Schistosomiasis was discovered in Malaysia in 1975 in an autopsy case. Since 1975 autopsies, surveys, and resurveys have been carried out to identify animal hosts, snail intermediate hosts, and reservoir hosts. Seroepidemiologic tests involving enzyme-linked immunosorbent and circumoval precipitin methods have been used to determine the true incidence and prevalence of this protean disease among the Orang Aslis (aborigines) in Malaysia. With the use of better epidemiologic and parasitologic tools, more cases of schistosomiasis are being reported.
The first two cases of human muscular sarcocystosis are reported from East Malaysia, in Sabalt and Sarawak respectively. Sarcocysts were seen iin biopsied specimen from the nasopharynx of both patients who had carcinoma of the nasopharynx. The measurements and appearances of the cysts and the zoites within the cysts were compared with the human cases of sarcocystosis previously reported in West Malaysia. Zoonotic and other aspects of these cases of East Malaysian sarcocystosis are discussed.
The historical background, epidemiology and changing pattern of clinical disease as seen in Malaysia is reviewed. The preliminary results of the longitudinal study of epidemiology of dengue in Malaysia is also presented. Studies led by Rudnick et al. over some 18 years have established that the disease is endemically transmitted by both Aedes aegypti and Aedes albopictus causing illnesses ranging from mild febrile episodes through classical dengue fever, dengue haemorrhagic fever and the dengue shock syndrome. The first epidemic occurred in 1962 in Penang, and the second major epidemic in 1974 in Selangor. From then on epidemics seem to occur every 4 years, i.e. 1978, and then in 1982. With increasing number of cases being seen from the end of 1985 and in 1986, and with the increasing numbers of positive virus isolates, another epidemic may occur this year. Though in the early years, mainly children were affected, recently more cases are being seen in 16-30 years age group. There is also a changing pattern in the clinical presentation of the cases. The clinician has to be aware of the various modes of presentation of this sinister disease. A high index of suspicion is needed for early diagnosis, as management is mainly symptomatic and there is no specific drug as yet to combat the shock and bleeding manifestations.
A rare complication of per rectal extrusion of a ventricule peritoneal shunt catheter occuring in a four-month old Chinese baby boy with hydrocephalus is described. Perforation of the bowel by the shunt occurred without any peritonitis or retrograde infection of the shunt system. Its pathogenesis and diagnosis are discussed.
A nation-wide outbreak of 260 cases of DF/DHF with 1 death occurred in Singapore from Apr-Sept 1986. The outbreak originated from 3 separate foci of transmission at the western, south-eastern and north-eastern parts of the island and then spread to other dengue receptive urban and suburban areas. The morbidity rate was highest in young male Chinese adults between 15 and 24 years of age. The outbreak was rapidly brought under control through destruction of adult Aedes mosquitoes, surveys and source reduction of larval breeding habitats, health education and to a certain extent law enforcement. The Aedes population was high in the main foci of transmission although the overall house index was only 1.1. Other factors which could have precipitated the outbreak included waning herd immunity of the human population and continuous introduction of dengue virus into the country.
In Malaysia, the elderly are still a relatively neglected group of people in that little priority is given to the important health issues associated with an aging population. This paper examines some of the relevant findings obtained during a survey which was carried out in 1984/1985. These findings have serious policy implications concerning family support, work, income, retirement, community involvement, social network, transport, and housing as pertaining to the elderly. There is an urgent need, as the population ages and social changes occur in society, for health planners, politicians and policy-makers to scrutinise the existing policies and develop new policies so as to retain those traditional practices that support, improve and maintain the psychological and social well-being of the elderly; and to develop new policies and programmes thus promoting a better lease of life for this small but important group to whom we owe so much.

A six-month survey of 828 patients admitted to the Coronary Care Unit (CCU) of the General Hospital, Kuala Lumpur was carried out to ascertain whether the smoking habits of the patients predisposed them to definite coronary events and its immediate outcome i.e. early mortality (within seven days). The various ethnic groups were also screened to determine if they were at increased risk to coronary events in relation to other known risk factors. Three hundred and eleven patients - 239 males, and 72 females - had confirmed acute myocardial infarctions of whom 190 were smokers (172 males, and 18 females). Sixty-nine infarct patients died within the first seven days post-Ml: 35 were smokers (50.7%). Two-hundred and eighty other patients had non-infarct coronary events. Of these, 167 were smokers. In contrast, only 99 out of 237 patients admitted for non-coronary events, were smokers. It thus appeared that patients admitted to the CCU for suspected cardiac events had a greater incidence of confirmed acute myocardial infarction or acute coronary events if they were smokers (p < 0.001). Mortality from these coronary events was not seen to increase among smokers in this population sample. Women who smoked as a whole, were not found to be at increased risk to coronary events, but women smokers 60 years and older were shown to be at increased risk to developing confirmed coronary events (p < 0.01).
This study analyses retrospectively the results of sixteen acute dislocations of the knee at the University Hospital, Kuala Lumpur from 1980 to 1985. The average follow-up was 3.5 years. There were seven posterior, six anterior, one lateral and two postero-lateral dislocations. All were due to motor vehicle accidents except one. There were four patients with popliteal artery injury and two patients with peroneal nerve injury; three required amputations due to late detection. All the peroneal nerve palsies were permanent. The results of surgical treatment appear to be better than conservative management of acute dislocation of the knee.
Forty-eight patients treated surgically for chronic subdural hematoma in General Hospital Kuala Lumpur were studied retrospectively. The clinical presentations were insidious and nonspecific. A high clinical index of suspicion for this disease is required. Diagnosis is confirmed by CAT Scan of the brain with or without cerebralangiography. Treatment consists or burr-holes and drainage
Over a period of nine years, from June 1976 through May 1985, 18 cases of ruptured sinus of Valsalva aneurysms were seen at the University Hospital, Kuala Lumpur (UK KL). Seven of these cases were treated surgically. The majority of patients were males, with a mean age of 26.6 years. All cases were symptomatic. The site of aneurysm was the right coronary sinus in five patients and the non-coronary sinus in two patients. All aneurysms ruptured into the right ventricle. The fistula was closed via a transaortic approach. In addition, repair of the right heart chamber was necessary in six patients. There were no deaths. Clinically significant morbidity included aortic regurgitation in one patient and residual fistula requiring reoperation in another. The long term follow-up at two years was excellent.
Thirty-four patients with intracranial arteriovenous malformations seen in the University Hospital, Kuala Lumpur, over a is-year period were reviewed. A VM was found to be more common in young, male patients with preponderance Chinese origin. The advent of the Cl-scan has increased the detection of small A VMs and intracerebral haematomas proportionally. The majority of the lesions were situated in the posterior half of the brain unlike the distributions in patients in the West and in Singapore. On the other hand, most of the intracranial bleeding were subarachnoid haemorrhage; a presentation similar to the western community, but unlike that reported from Singapore. The treatment policy is not unlike the western community with good results in 82% of patients selected for surgery.
Retrograde ureteroscopy, using the 12.5 French Storsz Perez-Castro Ellendt operating ureteroscope provides excellent visual access to the whole of the ureteric lumen in most instances. A total of 41 ureteroscopies were performed on a similar number of patients over a period of 12 months since April 1986. Majority of them were for ureteric calculi. Success rate for patients with ureteric calculi below the pelvic brim was 77.4%. A lower success was noted for calculi above the pelvic brim (50%). Retrograde ureteroscopy will eventually make blind basketing of lower ureteric stones an unnecessarily risky procedure and perhaps even obsolete. Ureterolithotomy nevertheless will still have a place in the management of stones that cannot be extracted either due to acute bullous oedema of the ureteric mucosa or in previously explored rigid non-yielding ureters not suitable for ureteroscopy.
We present four cases of polymyalgia rheumatica who recently came under our care. The dramatic response of this disorder to low dose corticosteroids is well illustrated by our patients. The pertinent features of diagnostic value in this condition are highlighted.
The puffer fish belongs to the family Tetraodontidae and has one identifying characteristic which is the ability to inflate itself by gulping in large quantities of air or water. They are commonly found in estuarine and inshore water. The viscera (ovaries, testes and liver) of puffer fish contain varying amounts of extremely potent toxins [tetraodontoxin). The most violent form of fish poisoning is produced by ingestion of tetraodontoid or puffer-like fishes and this has been reported. The putftoad, Tetradon maculatum, has caused fatal poisoning? Despite the high toxicity of this group of fish, the meat is commonly consumed by some fisherman in Sabah without much morbidity. In Japan, puffer fish, called "fuqu" commands the highest prices in food fish and are prepared and sold in special restaurants where specially trained cooks are employed to prepare the "fuqu". Nevertheless it is still the primary cause of food poisoning in Japan especially among the lower socio-economic classes who fail to take the necessary precautions. In Sabah, four cases of puffer fish poisoning resulting in one death have been documented." We report herewith another incidence of puffer fish poisoning in which 18 persons from seven families were affected with nine deaths from two families.
A successful excision of a giant cerebral mycotic anuerysm in a young girl with endocarditis is presented. The clinical pictures can be confused with a cerebral abscess. C.T. Scan and angiography are essential in the diagnosis. Rupture of the aneurysm is associated with high mortality and morbidity which can be averted by prompt neurosurgical treatment.
