A total of 1,688 non-repeat upper gastrointestinal endoscopies performed over a 33-month period from April 1985 to December 1987 at a University Medical Unit in Kuala Lumpur was analysed for a profile of peptic ulcer disease amongst Malaysians. There was a total of 360 peptic ulcer patients with a gastric ulcer to duodenal ulcer ratio of 1:1. The male: female ratio was 2.8: 1 for duodenal ulcer and 1.8:1 for gastric ulcer, and 2.3:1 for peptic ulcer overall. In both sexes, gastric ulcers were seen at an older age group compared to duodenal ulcers.
Of the three main Malaysian ethnic groups of Malays, Chinese and Indians, Chinese of both sexes had the highest frequency of gastric ulcers. Chinese females had the highest frequency of duodenal ulcers.
Studies were carried out on the suppression of both exploratory and spontaneous locomotor activities in the mouse by a non-polar fraction from a methanol extract of the dried leaves of Psidium guajava. Shortly after intraperitoneal administration of this fraction, typical narcotic-like effects were observed, including catalepsy, analgesia, Straub tail, shallow respiratory movements and exophthalmos. The dose for 90% suppression of exploratory activity was between 3.3 and 6.6 mg/kg intraperitoneally and the onset of action was 6-8 min. The duration of activity was dose-dependent and, for a dose of 13.2 mg/kg given intraperitoneally, it was found to be more than 6 h. Qualitatively similar results on exploratory activity were obtained when the extract was administered orally. Doses of 3.3-6.6 mg/kg i.p. depressed spontaneous locomotor activity and tunnel running was curtailed. Higher doses abolished the spontaneous locomotor reflex action. A flavonoid compound or compounds appear to account for the activity seen.
This paper discusses the spectrum of rheumatic diseases seen over a 24-month period from January 1986 to December 1987. Rheumatoid arthritis was the commonest rheumatic disorder seen, comprising of 47.1 % of all cases and ankylosing spondylitis was among the least frequent (0.9%). Most of the rheumatic diseases reported in the West are also seen in Malaysia. However, results of this study which is based on the hospital population may not be representative of the spectrum of rheumatic diseases in the our population.

PIP: The influence of socioeconomic status (ethnicity, income and parity) on electrolyte composition (sodium and potassium) in human milk is little known. We have thus quantitatively analyzed approximately 700 samples of milk (1-90 days postpartum) obtained from healthy Malaysian mothers' (Malay, Chinese and Indians) of full term infants. Results show that the mean concentration (mmol/l) of sodium is highest (48.2+or-1.7, Mean+or-SEM) in the Malaysian mothers' colostrum and this value decreased by 30% in their transitional milk and remained constant throughout subsequent days of lactation (mature milk). Ethnically, it is found that the level of sodium in colostrum of Malay and Chinese mothers were similar while the Indian mothers' colostrum showed apparently higher value (52.7+or-3.4 mmol/l) that is statistically insignificant. The transitional milk of all 3 ethnic groups studied exhibited similar levels of sodium. On subsequent days of lactation (mature milk) the Malay mothers exhibited lowest concentration (25.9+or-2.6 mmol/l) of sodium that is significantly (P0.05) different from that of Chinese and Indian mothers. Income and parity do not significantly affect the sodium level in Malaysian mothers' milk during all stages of lactation studied. The level of potassium, however did not change significantly with days of lactation. Like sodium, potassium too was not influenced by income and parity. (Author's).

PIP: In 1986, single puncture laparoscopic application of the Filshie clip was introduced into Malaysia's National Population and Family Development Board's female sterilization program for an evaluation. A total of 42 female sterilizations were performed by this method between June 1986 and December 1986. Laparoscopy was performed on an outpatient basis under local anesthesia. In 37 cases, the sterilization was interval. Filshie clips were successfully applied to the fallopian tubes of 40 women; in the remaining 2 cases, the latching mechanism jammed and Falope rings were used instead. The average time from application of 1st clip to skin closure was 10 minutes. During clip application, technical problems (faulty applicator, clip fell into the pelvic cavity, failure of latching mechanism) were encountered in 4 cases and surgical difficulties (poor visualization, hydrosalpinx, and tubal adhesions) occurred in 10 cases. In general, complications were minimal: 1 patient developed cynosis after anesyhesia (Pethidine) injection, the omentum was torn during introduction of the trocar in another, and a 3rd patient developed thrombophlebitis at the intravenous site. Only 1 pregnancy was recorded during the follow-up period; this occurred 15 months postoperatively and was intrauterine. Given the facts that this procedure is easy to learn, fast and simple, associated with no more complications than other laparoscopic procedures, and is cosmetically more acceptable to women, its more widespread application is recommended.
