Transurethral Resection of the Prostate (TURP) is now the preferred method for dealing with the obstructing prostate. This procedure was reintroduced to the Penang General Hospital in August 1985. Over the next one and a half years, 100 TURP were performed by the author (NYTL). This paper reviews this initial experience. Of the patients, 17.7% required blood transfusion of one unit each. The mean post operative stay was 4.8 days. There were no immediate deaths. This experience confirms the acceptable results of TURP in the treatment of patients with benign prostatic hypertrophy in the Malaysian context.
The dorsal skin of 18 healthy Sprague-Dawley rats was used to investigate the reaction of connective tissue to buffered and unbuffered glutaraldehyde. Both the agents produced well-circumscribed lesions that underwent resolution within 30 days. Observation also shows that 2.0% buffered and unbuffered glutaraldehyde maintained a relatively inflammation-free status in connective tissue.
Antibiotic resistance in Gram-negative bacteria, particularly Salmonella and Shigella, requires surveillance worldwide. This study describes results of surveys in Hong Kong, Bangkok and Kuala Lumpur. All strains were isolated in hospitals which have large community catchment areas in addition to specialised hospital units. The prevalence of resistant strains was high in all areas. Gram-negative bacteria such as Enterobacter associated with hospital infections were resistant to penicillins and cephalosporins, with gentamicin resistance ranging from about 20% in Kuala Lumpur and Hong Kong, to 35% in Bangkok. Ninety-seven percent of Shigella isolated in Thailand were resistant to ampicillin. About 10% of Salmonella were resistant to chloramphenicol in all three centres.
A case of Waldenstrom's macroglobulinemia with classical findings of IgM paraproteinaemia and a typical lymphoplasmacytic marrow infiltrate is reported and the treatment of this patient outlined.
Over an 18 month period, 34,522 livebirths were delivered in the Maternity Hospital, Kuala Lumpur. 36 of them had Down's Syndrome. Based on our findings, the incidence of Down's syndrome among the Malaysian babies born in this hospital was 1:959 livebirths. According to racial distributions, the incidence among Malay was 1:981 livebirths, Chinese 1:940 livebirths, and Indian 1:860 livebirths. Our incidence was lower than those from the Western populations. Unlike others' studies, there was also a female preponderance of Down's syndrome among the Malaysian babies.
Five strains of Ma. uniformis from Malaysia were tested for their susceptibility to infection with subperiodic B. malayi. All were found to be susceptible with infection rates ranging from 62% to 100%. The susceptibility rates were directly related to the microfilarial densities of the cat at the time of feeding. Statistical analysis showed no significant difference (p greater than 0.05) among the means of the indices of experimental infection as well as the percentage of infective mosquitoes of the five strains and an old laboratory colony. They were all equally susceptible to subperiodic B. malayi.

Thirty-eight normal volunteers and 10 patients with untreated thyrotoxicosis were each given 0.5 ml of Lugol's solution daily for 10 days. On days 0, 5, 10, 15 and 20, serum levels of T4, free T4, T3 and TSH (by sensitive immunoradiometric assay) were measured. In normal subjects, the serum concentrations of free T4 declined significantly at day 10 while TSH levels were significantly increased at days 5, 10 and 15. Serum levels of T4 and T3 did not change significantly. All the observed changes took place within the limits of normal ranges for the hormones mentioned. In contrast, in the thyrotoxic subjects, both T4 and T3 were significantly decreased at days 5 and 10, while serum TSH remained below detection limit (0.14 mU/l) throughout the study. Short exposure to excessive iodide in normal subjects affects T4 and T3 release and this effect could be partially overcome by compensatory increase in TSH. In thyrotoxicosis, lack of compensatory increase in TSH results in rapid decreases in T4 and T3 levels. The integrity of the hypothalamo-pituitary-thyroidal axis may be effectively assessed by measuring TSH response to iodide suppression, using a highly sensitive immunoradiometric assay.
Serum IgG levels and complement C3 levels were assayed on Day 0, 1, 3-4, 7 and 56-70 post-treatment with diethylcarbamizine citrate (DEC) in a series to 26 patients with Brugia malayi infection and 6 volunteers without infection. On treatment, the microfilariae were cleared from the blood within 24 hours. The eosinophils decreased dramatically on Day 1 post-treatment but increased rapidly by Day 4 to 7 and then dropped to normal levels in 45 days. The serum IgG mean levels decreased briefly following treatment with DEC but then returned to original levels. However, the complement C3 levels gradually increased over the 2 months period of study reaching statistical significance levels (p less than 0.01) in patients with initial high blood microfilariae. The observation suggests that Brugia malayi infection probably induces a high rate of synthesis of complement C3 and this process continued in the post-treatment phase. Since, DEC treatment did not cause a decrease in complement C3 with the elimination of blood microfilariae, it would appear that the complement C3 is consumed following antibody attachment to the microfilariae as they enter the blood circulation.
The prevalence of clinically observed oral lichenoid reaction in 186 Malay army personnel using Fansidar for 9 weeks was found to be 4.8%. The prevalence was found to be 0.5% in 186 army personnel who had stopped using Fansidar for 2 months and 0% in 143 army personnel (control group) who had not used Fansidar for at least 4 months. The lesion showed a higher prevalence for the gingiva. There was no correlation between cigarette smoking and the occurrence of these lesions in each group.
One thousand consecutive cases of carcinoma of the uterine cervix treated in the General Hospital Kuala Lumpur between January 1977 to December 1979 were studied. Epidemiological breakdown by race, age, parity, occupation, stage and histology of the disease were obtained. Treatment complications in survivors available for follow-up were analysed. The Chinese had the highest incidence, followed by the Indians and the Malays. Ninety six percent were squamous cell cancers, the remaining were adenocarcinomas. Eighty percent of patients were seen at an advanced stage (Stage IIB-IV). Late radiation complications were mainly proctitis, cystitis and fistula; (5%, 7.2% and 1.4% respectively). These figures are comparable to many centres but the incidence of cystitis is relatively higher. This is believed to be related to irradiation techniques in these cases.
Eighty-six children diagnosed as child abuse and/or neglect were admitted to the Paediatric wards of the General Hospital, Kuala Lumpur during 1985 and 1986. Of these cases, 62 were of physical abuse, six of sexual abuse, one case of both physical and sexual abuse and 17 of neglect. There were 25 boys and 61 girls. Thirty-four of these children were Malays, 16 Chinese, 26 Indians, three mixed and seven illegal immigrants. Twenty-one were below the age of one year, 24 from one to four years, 25 from five to nine years and 16 were ten years and above. The abusers were mainly close members of the family. Of these children, 24 were sent back to their parents and 11 to their relatives home. Twenty-seven were taken into care by the Ministry of Social Welfare and the remaining seven children who were illegal immigrants, were deported with their parents. Only one child was successfully fostered. Eleven children were taken away from the hospital by their parents or guardians without the knowledge of the health staff. There were five deaths in the series.
A survey showed only 27% of our house-officers know how to intubate. Ninety-two percent however recognise the alternative to intubation. On the whole, knowledge centering around intubation is generally lacking.

The 'Priming principle' applied to non-depolarizing muscle relaxant atracurium was studied in 60 patients. This was a double blind study. The conditions observed for intubation were graded and the efficacy of priming dose of atracurium for shortening the onset time of intubation was studied. The patients were of ASA classification I and II and received standard premedication. The purpose of the study was to use the priming dose of atracurium to shorten the onset time of intubating dose of atracurium. This would be desirable in conditions requiring rapid intubation and in situations when the depolarizing muscle relaxant suxamethonium is contra-indicated. The results were statistically significant.
Percutaneous insertion of central venous catheter (CVC) is a valuable procedure in managing critically ill patients. However, placement of CVC is not without its complications. The author reports a case in which a CVC was inserted into the right pleural cavity which was not detected by the usual clinical methods of confirming catheter placement and an antero-posterior (A-P) chest x-ray.
Autoantibodies to the three extractable nuclear antigens (ENA), Anti-SSA (Ro), Anti-Sm, Anti-RNP and antinuclear antibodies were determined in 150 patients with SLE. Seventy patients (46.7%) had Anti-SSA (Ro), 40 (26.7%) Anti-Sm and 25 (16.7%) Anti-RNP antibodies. Ninety four percent patients had a positive Fluorescent anti-nuclear antibody (FANA) test. The commonest FANA pattern is the speckled pattern. Subclinical keratoconjunctivitis sicca (KCS) was present in 60% patients. No correlation could be demonstrated between the presence of ENA autoantibodies and the clinical features of patients.
In a two year period between 1985 and 1986, eight children presented with impacted blunt foreign bodies in the oesophagus were successfully treated by removal using a Foley catheter without anaesthesia. There were no complications. All patients were discharged well after one or two days in hospital. The technique is safe, rapid and easy to perform.
The abuse of phenylbutazone among rheumatoid arthritis patients has recently become a subject of interest. Unscrupulous manufacturers take advantage of the miraculous analgesic property of phenylbutazone and deliberately add this toxic drug in their preparations without declaring its presence on the label. In a recent survey, many such illicit preparations were seized from Chinese medical halls in Johor and sent to the Department of Chemistry, Johor Bahru for analysis. Here a Gas Chromatograph Mass Selective Detector (GC-MSD) method was developed for the determination of phenylbutazone in illicit traditional preparations.

Mesenteric venous thrombosis has been described to occur in cases where there has been no apparent cause. The diagnosis is usually delayed because the signs and symptoms are non-specific. A case of primary mesenteric venous thrombosis is reported below. Its presentation and pathology are discussed. Treatment is surgery with resection of gangrenous bowel and primary anastomosis. Post-operative anticoagulation is advocated.
A case of carotid body tumour is presented. Pathology, diagnostic investigations, modalities of treatment and prognosis are discussed. With greater awareness of this condition and improvement in diagnostic investigations and surgical techniques, the outlook in managing this condition should be better.
