An immunization survey was carried out in early 1983 in a military community. The survey covered 192 children from 147 families. 98% had BCG scars. and 94% had completed their primary course of immunization against diphtheria, pertussis, tetanus and poliomyelitis. The acceptance rate for booster was however low. The time frame for the immunization was also not adhered to strictly. An immunization register has been started in all centres for recall of defaulters. Publicity has also been mounted to ensure all are aware of the immunization programme.
A random sample of 102 hypertensives out of a total of 347 in the Malaysian Armed Forces were studied with regard to patient education, knowledge of hypertension and therapy compliance. It was found that for 53 percent, patient education was unsatisfactory and as a result 67 percent had inadequate knowledge of hypertension. Adherance to therapy - drug intake, weight reduction and cessation of smoking - was poor (more than 59 percent, 96 percent and 70 percent failure respectively). There was no significant difference between asymptomatically and symptomatically detected hypertensives.
288 notifications of syphilis in military personnel for 1974 to 1978 are analysed. 56 cases are primary and 232 are latent syphilis in service personnel and 13 in women and children. Antenatal screening detected 56 cases (0.9%) of syphilis. Only 24 cases among soldiers had confirmatory tests done. Treatment varied and some were inadequately treated, others overtreated and many with incorrect schedules. Intramuscular penicillin was the treatment of choice in 85% of cases. Follow-up of cases was inadequate. In all, it indicated a poor control programme for STD. A good programme is possible within the armed forces set-up and a number of measures are suggested.
A postal questionnaire survey was carried out among military doctors during June to August 1979 on habits and attitudes to smoking. An 87% response rate was obtained. Smoking prevalence was found to be 50%. 45% of medical officers are heavy smokers. Age at starting influence the amount smoked. Service life had no influence on smoking habits. Attitudes to smoking vary between the different categories of doctors. The habits and attitudes indicate a mental revolution on the part of doctors is required prior to any anti-smoking programme as they have to be sufficiently motivated to lead the fight.
279 cases of pulmonary tuberculosis were diagnosed during a 10 year period from 1969 to 1978. 60% as a result of self-referral and 40% from mass miniature radiography of the chest. For every case of pulmonary tuberculosis picked up, the number of MMRs required has been steadily rising from 1 in 1900 to 1 in 6700. Using South Korea study figures, it costs US$42600 for a case of pulmonary tuberculosis detected by MMR. Besides being not cost effective, there is little advantage in early detection with regard to prognosis, in preventing subsequent cases and in picking up other lung or cardiac abnormalities. Unnecessary radiation results from frequent MMR whose dosage is 10 or more times greater than standard chest X-rays. MMR should be limited to. contact tracing, prior to overseas courses and on termination of service.

200 doctors are gazetted as practising in Sarawak in 1982. 88% are males and only 12% are females. Of the 200, 65.5% are Chinese and the natives of Sarawak and Indians form 15.5% each. Nearly 30% are graduates from local universities, 44% from universities in Commonwealth countries and a few from universities in other countries. The majority of the doctors are under 40 years of age. 55 % are in government service, while 45% are in the private sector. All private practices are solo practices except three-one each in Kuching, Sibu and Miri which are based on partnership. The number of doctors with specialist qualifications is not known as it is not essential for these qualifications to be entered in the Register. The doctor-to-population ratio in Sarawak has improved from 1:14000 in 1964 to 1:6856 in 1982. To reach the Ministry of Health's target of 1:2500 by 1990, a yearly recruitment of 58 doctors would be needed from 1983 to 1990. This would be feasible if either an admission quota to the local medical faculties for Sarawakians is implemented or more doctors are posted to serve in Sarawak.
The 1980 malaria notifications in Malaysian soldiers are analysed. The number of new cases notified was 964, giving an annual incidence of11.81/1000 soldiers. Sixty-three percent were falciparum and 36 percent were vivax infections. There were 48 relapses and recrudescences. Twenty-three carriers were detected on mass screening. The yield from mass screening was very low - 5.09/1000 screened. The current practice of chemotherapy, though generally acceptable, was unsuitable for a number of patients. Recommended regimens are not being adhered to. There were two cases ofcerebral malaria, one of whom died.
Two outbreaks of mushrooms poisoning involving 3 and 9 soldiers respectively with one death on 9 March 1980 in Perak are described. The symptoms were compatible with muscarine [a neurotoxin] poisoning which was detected in the stomach contents of the dead soldier and the mushrooms consumed by one group.
Malaria is the most important communicable disease in the field for the Malaysian soldier. His chief weapon is chemoprophylaxis. This was proguanil hydrochloride in the '50s, changed to Daraclor in 1962; since late 1985, Fansidar only is used. The incidence of malaria over the years has fluctuated widely and had its peak in 1977 at 29.7/1,000 soldiers and since then has shown a downward trend. Studies carried out to study the problem are noted briefly. Antimalarial discipline in the field, continued surveillance and integrated control measures in the base are emphasised in the fight against malaria.
