An outbreak of fever at Morib in the Federated Malay States
Mortality statistics of Peninsular Malaysia for the period 1950-1989 have been studied in relation to cardiovascular diseases, with particular emphasis on coronary heart disease as an important cause of death. It was observed that among six major disease groups reviewed, cardiovascular diseases which occupied third place as a cause of death in 1950 emerged as the number one killer during the 1970s and has remained so since (with exception in 1980). In contrast, infectious diseases which ranked first in 1950 dropped to fourth position in 1980. Between 1960 and 1980, mortality due to cardiovascular diseases was higher in males than in females. This tendency became less apparent during 1985-1989. With reference to race, the incidence of cardiovascular deaths was highest in Indians followed by Chinese and Malays. Among the specific cardiovascular diseases, coronary heart and cerebrovascular diseases accounted for the main causes of mortality. Mortality due to coronary heart disease has increased by more than three fold over the last 40 years and is still rising. However, mortality incidence due to rheumatic heart disease and hypertension decreased during the same period. In 1965, mortality due to coronary heart disease was highest in the 55-59 age group. In recent years (1985 to 1989), it shifted to the older age group (i.e. 65-69). There was a tendency for higher mortality due to coronary heart disease in males compared to females. Indians had a higher mortality due to coronary heart disease than Chinese and Malays.
An excess of male over female deaths is characteristic of modern national populations, whereas in some high-mortality societies female mortality exceeds that of males. Among the Semai Senoi, a Malaysian Orang Asli ("aboriginal") population, women experienced higher mortality than males in the decades before 1969. This differential occurred in all age classes older than 15 years so that the sex ratio progressively increased with age. A recent (1987) restudy of the Semai population found that sex-specific differential mortality is much reduced. A comparison of the 1969 and 1987 life tables shows a sharp shift in the sex ratios of mortality for the post-15-year-old age classes (the geometric means of age classes 15-44 were 0.768 in 1969 and 0.997 in 1987) so that male and female expectations of further life at age 15 are now nearly identical. In contrast to the best-known cases of high female mortality (mostly in South Asia), Semai sex differential mortality does not include the childhood ages. The Semai have traditionally been relatively sexually egalitarian, and sex bias in care has not occurred. Analysis of sex-specific causes of death for the pre-1969 population suggests that maternal mortality is the major cause of the excess female deaths. The reduced number of maternal deaths seems largely due to better health care, particularly the availability of hospital services. Interestingly, the reduction in female mortality has occurred simultaneously with increased fertility, and overall mortality has continued at relatively high levels (eO less than 36). Thus, rather than forming a component of a unitary demographic transition, declining sex differences in mortality can be accounted for by a specific factor, better maternal care.
A 2-year study was carried out in the Maternity Hospital, Kuala Lumpur to determine the neonatal mortality rates. This Hospital functions both as the local service centre as well as the national referral centre in Malaysia. Its neonatal services, however, were equipped and manned at those below Level III perinatal centre. During the study period 52, 877 livebirths took place in the Hospital. In 1987 and 1988 respectively, the low birthweight (less than 2500 gm) rates were: 112.8 and 101.9 per 1000 livebirths, very low birthweight (less than 1500 gm) rates: 11.1 and 8.8 per 1000 livebirths, neonatal mortality rates: 12.5 and 10.7 per 1000 livebirths and neonatal mortality risk ratio: 1.15 and 1.27. There was significant difference in mortality rates among the Malay, Chinese and Indian babies born in this hospital: the Indians had the highest and the Chinese the lowest rates. Babies delivered by breech or lower segment Caesarean section (LSCS) also had significantly higher mortality than those delivered by other modes of delivery. Low birthweight neonates constituted less than 45% of the total special care nursery admission but contributed to more than 70% of the total neonatal deaths. The common causes of neonatal deaths were problems of prematurity, infection, asphyxia and congenital malformations. Preterm and low birthweight neonates died primarily from problems of prematurity or infection. Term and larger neonates died mainly from asphyxia. More than 75% of the neonatal deaths occurred before 7 days of life. Improvement of antenatal care in the community and upgrading of perinatal services in this Hospital could help to lower the morbidity and mortality due to preventable causes.
Between January 1989 to April 1990 (16 months), a prospective observational study was carried out on 329 consecutive very low birthweight (VLBW) less than or equal to 1500 grams) Malaysian neonates born in the Maternity Hospital, Kuala Lumpur before their first discharge from the hospital. The objectives of the study were to determine the common causes of early morbidity and mortality of this group of Malaysian neonates. The study shows that the incidence of Malaysian VLBW neonates was 9.9 per 1000 livebirths (95% confidence intervals 9.0 to 10.8). The mean duration of stay in the hospital was 19.3 days (SD = 21.4). One hundred and ninety-six (59.6 percent) of the VLBW neonates died. They accounted for 60 percent (196/334) of all neonatal deaths in the hospital during the study period. Mortality was significantly higher in neonates of birthweight less than 1000 grams (p less than 0.01) and of gestation of less than 33 weeks (p less than 0.001). The three most common clinical problems were respiratory distress syndrome (RDS) (72.6 percent), septicemia (28.0 percent) and intraventricular haemorrhage (IVH) (21.9 percent). Death occurred in 71.1 percent of the septicemic patients. The most common causative organisms of septicemia were multiresistant klebsiella (52.3 percent) and multiresistant acinetobacter (14.7 percent). RDS (33.2 percent), septicemia (29.6%) and IVH (17.9 percent) were the three most common causes of death. Improvement in the nursing staff situation and basic neonatal care facilities in this hospital and prevention of premature delivery could help to decrease morbidity and mortality in this group of neonates.
Identifying the nutrition problems of Asia and the Pacific is made difficult by the enormous geographic, socioeconomic and cultural diversity that exists in these areas. With increasing longevity and reduced infant mortality, the more chronic diseases are becoming increasingly important. For almost 90% of the countries that keep such data in the Western Pacific Region of WHO, at least three of the five leading causes of death are noncommunicable diseases. Nevertheless undernutrition is still the most important nutritional problem in the Region. Even though there have been some encouraging declines in the proportion of malnourished under 5-year-olds, increasing populations have meant the actual numbers have not declined. Vitamin A deficiency, iodine deficiency disorders and iron deficiency anaemia remain major public health problems in many countries. There is evidence that vitamin A deficiency is appearing in countries in which it has not previously been a problem. New challenges are occurring, such as childhood obesity, the susceptibility of undernourished populations to the human immunodeficiency virus and the increase in noncommunicable diseases. The three arms of clinical nutrition: therapeutic, research and public health will need to work closely to meet the considerable and continuing threat posed by the nutrition-related diseases.
This study used path analysis to assess the chances of survival of babies in a neonatal intensive care unit in Lansing, Michigan, USA. Two paths to neonatal survival were identified and the variables accounted for 20% of the variance in gestational age. The first path showed that prior infant losses were negatively correlated with gestational age while in the second path, gestational age showed negative relationships with pre-pregnancy weight and household job worries.
The Malaria Eradication Program was started in 1967 in Peninsular Malaysia. Since then and up to 1980, there was a reduction in the number of reported malaria cases from 160,385 in 1966 to 9,110 cases for Peninsular Malaysia. Although the concept of eradication has changed to one of control in the 1980, the anti-malaria activities have remained the same. However, additional supplementary activities such as the use of impregnated bednets, and the Primary Health Care approach, have been introduced in malarious and malaria-prone areas. Focal spraying activity is instituted in localities with outbreaks in both malaria-prone and non-malarious areas. Passive case detection has been maintained in all operational areas. In 1990, 50,500 cases of malaria were reported of which 69.7% (35,190) were from Sabah, 27.8% (14,066) from Peninsular Malaysia and 2.5% (1,244) from Sarawak. Until June 1991 a total of 18,306 cases were reported for the country. Plasmodium falciparum continues to be the predominant species, contributing to 69.6% of the parasites involved. The case fatality rate for 1990 was 0.09%. There were 43 deaths all of which were attributed to cerebral malaria. The problems faced in the prevention and control of malaria include problems associated with the opening of land for agriculture, mobility of the aborigines of Peninsular Malaysia (Orang Asli) and inaccessibility of malaria problem areas. There is need to ensure prompt investigation and complete treatment of cases especially in malarious areas. The promotion of community participation in control activities should be intensified. Primary Health Care should be continued and intensified in the malarious areas.(ABSTRACT TRUNCATED AT 250 WORDS)
Significant advances in diagnosis and management have cured the majority of children with cancer. In the leukaemias, the commonest childhood malignancy, intensive induction-consolidation is important to ensure a lasting cure in about 65-80% and to eliminate the traditionally bad prognostic risk factors associated with less intensive treatment. Bone marrow transplantation (BMT) has a curative role in the minority who relapse particularly while on treatment. With few exceptions, most paediatric solid tumours are curable. Although the multimodal approach is responsible for the progress made, chemotherapy has emerged to play a dominant role. It has, in several tumours, obviated or reduced the need for radiotherapy and/or surgery. In Wilms' tumour and Hodgkin's disease, refinement of treatment is now in progress to reduce therapy-related morbidity while not sacrificing efficacy.
Twenty-nine patients (16 males, 13 females) with spontaneous pneumothorax admitted into Hospital Universiti Sains Malaysia, Kubang Kerian, from September 1984 to September 1990 were reviewed. Their ages ranged from newborn to 75 years. The commonest chief presenting symptom was dyspnoea (69%), followed by chest pain (35%). Four patients had chronic obstructive airway disease, 7 had pneumonia, 2 had pulmonary tuberculosis, one patient had emphysema while 4 patients had multiple underlying lung disorders. The left and right lungs were involved with equal frequency. Bilateral pneumothorax occurred in one patient. Most patients had a single episode of pneumothorax but recurrent pneumothoraces occurred in 3 patients (10%). Six patients were observed conservatively, 20 patients required chest tube insertion alone and 3 patients also required pleurodesis. Death occurred in 8 patients (28%) mainly due to coexisting infection and respiratory failure.
An open prospective descriptive pilot study was undertaken to assess the effectiveness and experience in the use of ExosurfNeonatal, a synthetic surfactant, on preterm infants with respiratory distress syndrome in the neonatal intensive care unit of the Paediatric Institute. Of 10 infants treated, seven (70%) survived with no major handicap on discharge. The mean duration of ventilation for these survivors was 6.4 days, mean duration of oxygen therapy 9.1 days and mean length of hospital stay 38.3 days. A comparison was made with a retrospective analysis of 15 neonates who were admitted during an eight month period prior to the pilot study. These infants were mechanically ventilated for respiratory distress syndrome but not given surfactant therapy. Of these, nine (60%) survived (P > 0.1 compared to Exosurf treated infants), but two developed post haemorrhagic hydrocephalus requiring shunting. For these nine survivors, the mean duration of ventilator therapy was 12.6 days, the mean duration of oxygen therapy 20.7 days and the mean length of hospital stay 70.8 days. This difference was statistically significant (P < 0.05). Of the three ExosurfNeonatal treated infants who died, two were extremely premature. Both developed grade IV periventricular haemorrhage while the third infant was admitted in shock and hypothermia and died from intraventricular haemorrhage and pulmonary interstitial emphysema. Except for the very sick and extremely premature infants, surfactant therapy is useful in reducing the mortality and morbidity of premature infants with respiratory distress syndrome in our neonatal intensive unit.
Obstetric pulmonary embolism forms the most serious vascular problem during pregnancy. The following report is a retrospective study into maternal deaths in Malaysian mothers probably due to obstetrical pulmonary embolism. Obstetric pulmonary embolism can be divided into amniotic fluid embolism and obstetric blood clot embolism. There were 37 maternal deaths attributable to this cause -9.9 per cent of all maternal deaths to blood clot embolism and 6.7 per cent to amniotic fluid embolism. Most cases were diagnosed clinically because a postmortem examination was not done. Eleven cases of embolism were associated with Caesarean delivery. The typical profile of a Malaysian mother dying from obstetrical pulmonary embolism is that of a Malay mother in the "non-risk" parities of one to four and usually aged between 31-35 years. In the management of these patients, there should be an urgency in diagnosis and improvement in diagnostic procedures. Health staff at all levels should be trained to pick up patients who present with features of deep vein thrombosis.
