A survey of a total of 1,157 Indian primary school children from eight schools from urban and rural areas in and around Kuala Lumpur showed an overall
prevalence of infection with soil-transmitted helminthiasis of 89.02%. The prevalence and intensity of infection were consistently high among both school boys and girls throughout the six years of primary school. The predominant helminth was Trichuris trichiura - both as single and mixed infections. The commonest type of helminthic infection among urban primary school children was mixed infections with Trichuris trichiura and Ascaris lumbricoides. Hookworm infections, both as single or mixed infections, were more common among school children from rubber and oil palm estates in the rural areas.
A retrospective study of the indications for temporary transvenous pacing in the University Hospital, Kuala Lumpur, from 1971 to 1979 is reviewed. There were 111 patients. The main indications for temporary transvenous pacing were, namely,complete heart block (57%), sick sinus syndrome (24%), Mobitz type 11 block (5%) and bifascicularblock (3%).
A double-antibody radioimmunoassay technique has been used to investigate the serum prolactin (hPRL) level in Malay females from premenarche to the postmenopause. The results showed that the hPRL level (mena ± SEM) in the premenarchal, postmenarchal and late pubertal/reproductive subjects were 23.6 ± 2.3, 19.1 ± 2.0 and 22.7 ± 1.9 ng/ml respectively. In premenopausal women, hPRL level (11.8 ± 2.4 ng/ml) was significantly reduced (p < 0.01) compared to that of late pubertal group; the level declined even further after menopause (9.5 ± 1.7 ng/ml). Although the difference in the mean prolactin levels between premenopause and postmenopause were not significant, 73% of the postmenopausal women had serum prolactin concentrations below 10 ng/ml compared to 44% of the premenopausal and 10% in late pubertal group.
The effects of ethanol on gastric thromboxane B2 was studied in man. A single dose of 20 ml 15% ethanol significantly inhibited the gastric secretion of thromboxane B2 whereas 20 mls of 5% ethanol were without effect. It was concluded that ethanol can suppress gastric secretion of thromboxane B2 psychosis.
A food poisoning outbreak affected 114 female Malay students staying in a religious secondary school hostel in Klang. The students developed an illness mainly characterized by abdominal pain, nausea, vomiting and giddiness. The median incubation period in this outbreak was 2.5 hours. Laboratory examination of suspected food revealed 2.3 X10^6 Bacillus cereus organisms per gram of fried noodles. B. cereus was determined as the probable cause of this outbreak and the fried. noodles the most likely vehicle for the organism. An outbreak of B. cereus food poisoning is being reported in Malaysia for the first time.
This paper discusses the feasibility of using a free pericardial patch in repairing defects of the esophagus. The experimental model used is the dog. A piece of the side wall of the esophagus is first excised. This defect in the esophagus is then covered
with a free patch of pericardium. The animals are then sacrificed at sequential dates and the grafted site submitted for microscopic examination. The results show that a free graft of pericardium when used as a patch can prevent leakage of esophageal contents and allow healing of the defect without gross narrowing of the lumen.
Continuous brachial plexus block in six patients undergoing reimplantation of severed fingers or hand is described. The technique involved placement of a catheter within the neurovascular sheath enclosing the brachial plexus. This enabled us to give the local anaesthetic as required to last the whole duration of surgery.
A case of Tracheoesophageal Fistula (TOF) was presented where the blind upper esophageal pouch was mistakenly intubated; in spite of this, adequate lung ventilation was possible for more than one hour. This was only noticed by the surgeon upon incision of the lower end of the pouch.
A case of paranoid psychosis in myxoedema is described. Though depression is commonly encountered in myxoedema, the disorder can also manifest itself with schizophrenic features; this can lead to problems in diagnosis and management.
13 patients with the amenorrhoea-galactorrhoea syndrome who conceived during treatment with bromocriptine were reported. Mean period of amenorrhoea was 3.0 years. In ten patients galactorrhoea was noted for a mean period of 4.2 years while in three it was discovered during examination. Seven patients presented with primary infertility. Menses returned in all cases after a mean duration of 2 months of treatment with bromocriptine at an average dose of 5. 86 mg daily. Mean serum prolactin was 4344 mUll (range 750 mU/l to 23,000 mU/l) before treatment and this declined to 186 mU/l with treatment. Seven patients became pregnant 5 to 25 months of treatment while six conceived after first menses. 21 pregnancies resulted from the thirteen patients. There was one spontaneous abortion and one premature delivery in which the baby died. Of the 16 live- births, there were twelve girls and four boys and their mean birth-weight was 2932 g. All were normal at birth and during subsequent developments except one with congenital dislocation of hip. It is concluded that bromocriptine is effective in restoring menstrual cycles and fertility by lowering serum prolactin in patients with the amenorrhoea-galactorrhoea syndrome. Bromocriptine may be safe for use during pregnancy, but it is suggested that the medication should be stopped immediately after conception unless tumour growth is apparent.
Physical abuse of women has been documented since the dawn of history. However, it is not frequent that such patients come for help as such. Rather, they present as part ofrelated complicated problems such as marital discord, attempted suicide, depression and even psychotic illness. Women have been traditionally considered to be the inferior sex and as such, in many countries, social rehabilitation is difficult within the legal rights granted by the provisions of the appropriate laws. Two cases of physical abuse were admitted to the University Hospital in 1981-82 and their difficult rehabilitation is described to highlight the inadequacies of the existing laws under which protection and rehabilitation of the patients were sought. An account of what was and could be done for them is given.
A study was carried out by the Factories and Machinery Department of Malaysia to assess the problem ofoccupational exposure to inorganic lead in Malaysian battery workers. The eight factories studied were divided into two categories: large, multinational subsidiaries with good industrial hygiene measures and small, locally-owned companies with poor hygiene features. A total of 251 workers (221 males and 30 females) were included in the study. Personal air sampling showed that 47% of the samples in the small factories had lead-in-air levels exceeding 150 ug/m3, compared unth. 29% in the larger establishments. The highest air lead levels were found in the cutting, pasting/mixing and battery assembly sections. 86.7% ofthe female workers and 62.2% of the male workers in the smaller factories had blood lead concentrations above the proposed limits of 70 ug/100 ml (males) and 40 ug/100 ml (females). In contrast, only 7.6% of the male workers in the larger factories had blood lead levels exceeding the proposed limits. Three workers also had positive signs or symptoms on clinical examination. Legislation of specific regulations to protect the health of lead-exposed workers in Malaysia is currently being drafted by the government.
Anti-smoking measures, adopted by local authorities before the guideline on the ban of cigarette advertisement and anti-smoking campaign launched by the Government, are limited in scope and area. The activity is limited mainly to a ban on cigarette advertisements in theatres. Legislative measures are instituted only in the City Council, Municipal Councils and 2 ofthe 20 district councils surveyed. There is an awareness among several local authorities on the need for an increase in anti-smoking activities but action. is lacking. A population of 7.4 million. people lioe in areas controlled by the local authorities. The local authorities are expected to play a more active role along with other Government departments following a directive in August 1982 from the Chief Secretary to the Government.
110 normal, healthy adults were tested for antibody to hepatitis A (anti-HA) type IgG and 86 (78.2%) were found to be positive. An age-specific prevalence wasfound to be lowest in the lower agegroup and highest in the higher age-group. Out of 24 IgG positive individuals, only one was found to have type IgM. No significant difference in the incidence ofanti-HA type IgG was found between 42 patients in the Urology Unit, General Hospital, Kuala Lumpur and normal individuals (P > 0.1). 15 patients diagnosed as viral hepatitis were investigated for HA V IgG and IgM antibodies. 13 (86.7%) were positive for type IgG. Of this, only five (33%) were positive for the type IgM, suggesting that HA V is the cause of acute viral hepatitis in 33% of cases admitted to hospital as viral hepatitis.
Gall stone is responsible for about 1% of total small bowel obstruction, 1.2 and recurrent gall stone ileus is even more unusual. 3 Gall stone ileus is caused by the impaction of the stone in bowel lumen. It was first described in a patient examined at autopsy by Bartholin in 1654. This paper based on unusual recurrent intestinal obstructions by a gall stone. The patient presented with large bowel obstruction and it was due to a large gall stone impacted in the pelvic colon. Four months later the same patient presented with small bowel obstruction due to large gall stone impacted in the terminal part of the ileum at 61 cms from the ileo-caecal valve. Gall stone obstruction of the colon is one of the rare complications. This rare complication usually occurs in elderly females' in whom there is frequently an underlying pathological condition at the site of obstruction in the colon. The calculus usually migrates through a cholecysto-colonic fistula in case of large bowel obstruction. In case of a small bowel obstruction the calculus usually migrates through a cholecysto-duodenal fistula. Diagnosis can be established by plain X-rays of the abdomen where there is gas shadow in the biliary system, sometimes the gall stone can be seen if it is radio opague (10-16% gall stone is radio opaque) at the site of obstruction. Otherwise diagnosis is always
made at laparotomy.
2 cases of idiopathic paroxysmal choreoathetosis with late onset and non familial were described. Examinations and investigations were normal and both responded to phenobarbitone.
