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.
The clinical course of 18 patients with Wilson's disease is reported. There were 13 males and five females of whom one is Malay. The prevalence of Wilson's disease in Malaysia is probably the same as elsewhere. Being a genetic syndrome, the genetic carrier rate for Wilson's disease is probably lower amongst the Malays. At diagnosis, the clinical signs were predominantly hepatic in 10 patients, neurological in five patients with three asymptomatic cases. All patients were commenced on penicillamine but poor compliance was observed in many patients. Two patients defaulted follow-up and seven patients died. Out of the nine surviving patients, only four are well with no clinical symptoms.
Prostalase¿ has a probe that emits a laser beam at 360 degrees . Targeted obstructive prostatic adenoma tissue was heated to above the cytotoxic threshold temperature of 45 degrees C. After successful canine prostate study, from September 1992 to April 1993, 45 patients were treated. This paper reports the 9 months results of this initial cohort of patients. Prostatic and periprostatic temperature mapping showed the mean temperature within the adenoma zone was 49 degrees C, while the periprostatic tissue remained within the safety level of less than 42.5 degrees C. The mean prostate volume reductions at 3, 6, and 9 months were 36, 33, and 38%, respectively. Those patients whose surgery was unsuccessful had prostatic tissue removed by TURP at 2 to 3 months. This tissue revealed a definite zone of coagulative necrosis. For the clinical assessment, patients were divided into urine retention (UR) and nonretention (NR) subgroups. At 9 months, 20 of the 32 UR subgroup and 10 of the 13 NR subgroup patients were available for assessment. Due to poor response or complications, 6 of the 26 UR patients (23%) required ancillary treatment. Hence, 20 of the 26 cases (77%) remained catheter free and their mean maximum uroflow +/- SE was 9.6 +/- 0.7 ml/sec. Based on a Siroky normogram only 7 of these 26 patients (27%) became unobstructed. Two of the 12 NR subgroup patients (17%) required ancillary treatment. The mean maximum uroflow +/- SE was 10.7 +/- 1.2 ml/sec.(ABSTRACT TRUNCATED AT 250 WORDS)
The clinical performance of the Copper T380A (TCu380A) and the Multiload 250 (MLCu250) intrauterine devices (IUDs) were evaluated for 12 months in a group of women who had one of the two IUDs inserted. Results are from a randomized clinical trial conducted at four collaborating research sites located in three developing countries. The gross cumulative life-table pregnancy rate of the TCu380A IUD was significantly lower than the rate with the MLCu250 IUD at 12 months (0.5 and 1.2, respectively, p < 0.01). No statistically significant differences between the two study IUDs were found with regard to IUD expulsion or IUD removal due to bleeding/pain, personal reasons, medical reasons, or planned pregnancy. TCu380A IUD users were more likely to report experiencing increased dysmenorrhea (p < 0.01) or intermenstrual pelvic pain (p < 0.01) than were MLCu250 IUD users. However, few of these users discontinued use of their assigned IUD because of having experienced menstrual bleeding disturbances or intermenstrual pelvic pain. These data indicate that the TCu380A IUD may be a better option than the MLCu250 IUD for women wishing to practice highly effective long-term birth control without having to resort to hormonal methods.
Sixty-nine severely head-injured patients treated by general surgeons over a 28 month period with admission Glasgow Coma Scale motor scores of 3 to 8 were reviewed retrospectively. Fifty-one patients were comatose on admission with periods from injury to admission exceeding 4 h in 34 patients who were referred from peripheral hospitals. Forty patients with acute intracranial bleeding underwent emergency decompressive surgery with 13 good recoveries and 18 deaths; good recoveries were observed in 11 of 20 patients with extradural haemorrhages, one out of eight patients with subdural haemorrhages, and one of 12 patients with intracerebral and/or combined haemorrhages. Twenty-nine patients with no evidence of acute mass lesions were treated medically with sedation, mechanical ventilation and mannitol infusion for cerebral decompression with seven good recoveries and 16 deaths. There were 15 good outcomes in 40 patients with admission motor scores of 6, 7 or 8 and five good outcomes in 29 patients with scores of 3, 4 or 5. A good outcome of 29% in the study may be improved by (i) better neurosurgical training of surgical and nursing staff; (ii) provision of technologically advanced diagnostic and treatment modalities; (iii) an efficient referral system; and (iv) provision of effective long-term rehabilitation.
This trial was carried out in Hospital Kuala Lumpur. Fifty-two patients who were scheduled to receive their first or subsequent courses of cancer chemotherapy with single dose cisplatinum containing chemotherapy regimens were evaluated. Thirty-four patients were given ondansetron in one group while 18 in the other group received metoclopramide with dexamethasone. The response to treatment was categorised as complete (0 emetic episode), major (1 or 2 emetic episodes), minor (3 to 5 emetic episodes) or failure (> 5 emetic episodes or rescue medication). Among the 52 patients, a complete or major control (0 to 2 emetic episodes) was achieved in 23/34 patients (68%) from the ondansetron group and in 3/18 patients (17%) from the metoclopramide with dexamethasone group (p < 0.002) on day 1. Similarly, the control of nausea was greater in the ondansetron group compared with the metoclopramide with dexamethasone group (p < 0.0009) on day 1. Two patients were excluded (dropped out) after day one from each of the two study groups due to excessive vomiting subsequent to cisplatinum therapy. From days 2 to 6, there was a trend in favour of ondansetron. Both treatments were well tolerated. The results of this trial show that in the prophylaxis of nausea and vomiting induced by cisplatinum containing chemotherapy, the efficacy of ondansetron is superior to that of a standard anti-emetic combination, metoclopramide with dexamethasone.
Thirty-one healthy women who underwent Caesarean section were studied in a double-blind trial to compare the effectiveness of epidural 0.5% bupivacaine plain, 0.5% bupivacaine plus 100 micrograms fentanyl and 0.5% bupivacaine plus 50 micrograms fentanyl in the prevention of intraoperative pain. There was no difference in the quality of analgesia between the three groups. The incidence of complications was significantly higher in the 0.5% bupivacaine plus 100 micrograms fentanyl group compared with the other two groups.
A study was done on 638 infants with BCG related lymphadenitis seen between August 1990 and December 1993. Most infants (86.5%) had developed symptoms by six months after vaccination and the nodes became suppurative in 317. Surgical procedures were carried out in 82 cases and the rest were managed conservatively. The mean duration to resolution was 6.6 months (range 1 to 29 months). This outbreak was related to a change from the Japan to the Pasteur strain of BCG. The incidence remained high ( > 15 per 1000 live births) despite a dose reduction from 0.1 ml to 0.05 ml, but declined when the Japan strain was reintroduced in April 1992.

Nonsedating selective peripheral H1 receptor antagonists are an important advance in antihistaminic therapy in allergic patients. This is a randomised, double-blind parallel group study comparing the use of two such agents viz loratadine 10mg daily and astemizole 10mg daily for two weeks in 39 Malaysian allergic rhinitis patients. At these dosages, both drugs were demonstrated to be efficacious (p < 0.05) for controlling nasal symptoms and safe in terms of short term biochemical and haematological changes and adverse effects noted. Evaluating efficacy criteria utilised in this study loratadine and astemizole were comparable but loratadine was significantly more effective in three areas viz: (i) in diminishing nasal symptoms after 2 weeks of treatment (p = 0.03); (ii) physician's efficacy evaluation after 2 weeks' treatment (p = 0.009); (iii) patient's efficacy evaluation after 2 weeks' treatment (p = 0.019).

This is a retrospective study of the epidemiology, clinical features, laboratory findings, treatment and outcome of haemorrhagic disease in 42 Kelantanese infants who were admitted to Hospital Universiti Sains Malaysia during a 2-year period (1987-1988). Classical haemorrhagic disease of the newborn was the commonest presentation (48%), followed by early onset (29%) and late onset (24%) disease. Home deliveries accounted for 81% of the affected infants. Most of these babies were not given vitamin K at birth in contrast to those delivered in hospitals. All except one infant were breastfed. The six commonest presenting clinical features were pallor, jaundice, umbilical cord bleeding, tense fontanelle, convulsions and hepatomegaly. All the infants had prolonged prothrombin and partial thromboplastin times which were corrected by administration of vitamin K. Subdural haemorrhage was the commonest form of intracranial haemorrhage, followed by subarachnoid haemorrhage. The overall case fatality rate was 14%. The results of this study once again emphasize the value of vitamin K prophylaxis in the newborn.
We report the first double-blind, placebo-controlled study that assesses the efficacy and safety of omeprazole 20 mg daily in the maintenance treatment of duodenal ulcer. For the healing phase, 128 patients with endoscopically proven active duodenal ulcer and a history of three or more relapses during the 2 years prior to the study were treated until healing with omeprazole 40 mg daily for 2 and up to 8 weeks. One hundred and twenty-three patients whose ulcers were healed were randomized to receive omeprazole 20 mg daily (n = 60) or placebo (n = 63) for 12 months as maintenance treatment. Patients were interviewed at 3, 6, 9 and 12 months, and endoscopy was performed at 3, 6 and 12 months and whenever symptoms recurred. The healing rates of the 124 patients completing the healing phase were 84, 98 and 100% at 2, 4 and 8 weeks, respectively. During the maintenance phase, eight and four patients discontinued treatment from the omeprazole and placebo groups, respectively. The proportion of patients in remission in the omeprazole group and placebo group after 12 months were 94 and 9% respectively (life table estimates, P < 0.0001). No significant clinical or laboratory changes were observed in patients on therapy with omeprazole. Patients with a history of frequent relapses thus continued to have a very high relapse rate without prophylactic treatment. Omeprazole 20 mg daily was effective and safe in maintaining such patients in remission.
Twenty-four children under the age of 10 years with femoral shaft fractures were treated by early immobilization of fracture and application of hip spica cast. The average hospital stay was 3.5 days. The average shortening at time of fracture union was 15 mm. The average time of follow up was 6.7 months. All fractures healed, except for one, in an acceptable position. The average shortening at last follow up was 9.5 mm and the average overgrowth up to the time was 6 mm. There was no incidence of refracture, joint stiffness or any pressure sore.
One thousand one hundred and sixty three patients (male-852, female-311) with ureteric calculi requiring intervention were treated between April 1988 to July 1992. Four hundred and eleven cases were treated by ESWL Monotherapy, 414 by stone manipulation plus ESWL, 301 by retrograde ureteroscopic lithotripsy, 36 by percutaneous antegrade ureteroscopic lithotripsy and 1 case by open ureterolithotomy. There were 25 failures of the initial procedures. Only three cases that failed primary procedures required open surgery. Other complications include minor ureteric mucosal perforation (3%), infection (3%), transient moderate to gross haematuria (20%), loin ache (26.4%), irritative urination (34.4%) and low grade fever (30.1%). Current modalities used in the treatment of ureteric calculi produce good results and there is generally no primary role for any open surgery.
Antilymphocyte globulin (ALG) was given every other day for 5 doses with platelet transfusions immediately following ALG administration in 6 patients with aplastic anaemia. Four patients responded and 3 durable remissions were achieved. One patient relapsed and further treatment with anti-thymocyte globulin and cyclosporin also failed. One patient died of Flavobacterium septicaemia 6 days after completion of ALG. Our data suggests that using an alternate day regimen, a response rate similar to a daily regimen can be obtained.
Reports on the outcome of treatment in ALL in Asian (non-Caucasian) adults have been few, and published results compare very unfavourably with results of treatment from 'Western' centres. Seventy-four newly diagnosed Malaysian patients with ALL between the ages of 15 and 69 were treated from 1986 to 1990. The clinical features and prognostic factors were similar to those reported in 'Western' series. The chemotherapy protocol utilized was adapted from the one used by Hoelzer et al in the multicentre German study. The complete remission rate was 73%. The probability of continuous complete remission at 5 years was 29% with a median duration of remission of 15 months. This compares with Hoelzer's initial results of 77% CR rate and 35% CCR at 5 years. Patients with an initial white cell count of less than 30 x 10(9)/l at presentation were found to have a significantly better disease-free survival than those with a count of more than 30 x 10(9)/l (35 vs 22%, P = 0.026, univariate analysis). There was no difference in leukaemia-free survival according to age, sex, ethnic group, or immunophenotype. These results show that the use of moderately intensive chemotherapy protocols in Asian (non-Caucasian) patients achieves similar results to those used in Caucasians. We also showed that the difficulties in 'curing' approximately 70% of adult patient with ALL are universal.
This was a retrospective study of the clinical course of 164 adult inpatients with acute renal failure (ARF) at the Hospital of the University of Science Malaysia admitted from June 1986 to May 1990. The mean age was 49.8 +/- 17.2 years. 33.5%, 54.9% and 11.6% were surgical, medical and obstetrical patients respectively. Obstructive uropathy, poor cardiac output or decrease in intravascular volume and infection accounted for more than 67% of the cases. Acute renal failure was present at admission in 113 (69%) patients. The majority of the patients (80%) had nonoliguric acute renal failure with daily output of urine of more than 400 ml. Compared with nonoliguric patients, oliguric patients had higher mortality (56.3% vs 18.9%, p < 0.01), and needed dialysis more frequently (43.8% vs 12.9%, p < 0.01). Early recognition of acute renal failure, improvement in early treatment of renal stones and discerning use of nephrotoxic drugs could result in decrease in incidence and severity of renal failure.
A retrospective review of 80 patients who underwent scrotal exploration for presumed testicular torsion is presented. Of these, 67 patients were found to have torsion, and the testicular loss rate was 51%. Patients who experienced delays in scrotal exploration of more than 24 h from onset of symptoms had a testicular loss rate of 71%. These delays arose from both hesitation in seeking medical treatment and misdiagnoses. It is emphasized that an acute scrotum in a child or in an adolescent should be explored early to exclude torsion.
In this part of Malaysia, consent of splenectomy is virtually unobtainable, so we studied the outcome of ITP without this treatment option. Thirty-two adult patients were seen, but 7 defaulted before therapy evaluation. Of the remaining 25, 17 achieved a complete remission with prednisolone, but in only 8 was this prolonged. Twelve patients, who failed to respond to prednisolone or who required > 15 mg/day as maintenance, were offered splenectomy, but all fused. Of these 12: one has died from an intracranial haemorrhage; three others have defaulted while on no treatment with platelet counts of < 16 x 10(9)/1; one has had a baby who died from intracranial bleeding. The other seven patients have platelet counts ranging from 4 - 202 x 10(9)/1 with moderate bleeding on doses of prednisolone of 0-60 mg/day: long-term corticosteroid side-effect are evident in all but one of them. This study demonstrates that ITP patients who refuse splenectomy have a high morbidity.
