A total of 97 children aged 1 month to 16 years (mean 6.6 years) had upper endoscopies performed in Paediatric Institute, Kuala Lumpur Hospital between January 1997 and December 1999 for various gastrointestinal symptoms. Of these 70 children were tested for Helicobacter pylori. The four most common indications for upper endoscopy were recurrent abdominal pain, upper gastrointestinal bleeding, epigastric pain and vomiting. The overall prevalence of this infection in this heterogenous group of symptomatic children was 10% (7/70). This study shows that H.pylori positivity in a routine endoscopy population is low and does not appear to be associated with specific symptoms.
Thromboembolic disease remains an important cause of maternal mortality worldwide. The risk assessments for prevention of thromboembolism in pregnancy are controversial due to lack of large-scale randomised controlled trials. Unfractionated heparin is at present, the anticoagulant of choice during pregnancy. However, it may be superseded by low-molecular-weight heparin in the near future because of its safety and efficacy.
Objectives: A child's admission into intensive care is a major cause of stress for parents. However among Malaysian parents, data concerning the perception of stress are virtually absent. Therefore we conducted a study to measure the reliability of the Malay version of Parental Stressor Scale: Pediatric Intensive Care Unit (PSS: PICU) in identifying sources of stress and to study factors that might influence their stress response.
Methods: Over a six-month period, one hundred and twelve parents were requested to answer the questionnaires twice either in Malay or English, a week apart. Spearman's correlation and Cronbach's alpha coefficient was used to assess the repeatability and internal consistency of the questionnaires.
Results: Ninety-four (83.9%) and seventy-one (75.3%) parents responded to the first and second administration of questionnaire respectively. All answered in the Malay language except for three. The correlation ranged from 0.50 to 0.71 with a total score of 0.76. The Cronbach's alpha coefficient ranged from 0.75 to 0.93, with total a score of 0.95.
Alteration in parental roles was the most stressful source of stress. Fathers, parents of children with higher PRISM score and parents with no previous admission into intensive care unit scored significantly higher in staff’s communication.
Conclusion: The Malay version of PSS: PICU is reliable in identifying sources of stress. Alteration in parental roles was the most stressful source of stress. Parents' gender, previous experience and severity of the child illness may influence their stress responses.

The current treatment options for beta thalassaemia major patients include conservative treatment with blood cell transfusions and iron chelation or stem cell transplantation. Regular blood transfusions inevitably lead to multi-organ haemosiderosis and are attended by risks of blood-borne infections. Results from stem cell transplantation are good and suggest that this should be offered as first line therapy when a matched sibling donor is available because the patient is often cured and able to live a normal life. Of 38 Malaysian children who underwent bone marrow or cord blood transplantations using matched sibling donors, 29 (76%) are now cured.
Purpose: This study aimed at evaluating the educational value of the morbidity mortality meeting and benefits obtained from it so as to implement changes that can improve it.
Methods: Surgeons (n=13) at a university hospital responded anonymously to a questionnaire which was structured to monitor the educational activity of the morbidity mortality meeting. They indicated their perceptions on a five-point scale (very poor, poor, fair, good and very good). Depending on the results of the first questionnaire, these changes were made: 1) Standardisation of the notice of the meeting 2) Organization of the meeting 3) Review of the literature on the specific problems encountered. The participants were not aware of the results of the first questionnaire. Nine weeks later, the same questionnaire was repeated (n=12). Mann Whitney test was used to compare the ratings of the two questionnaires.
Results: The attributes which showed significant improvement between the first and second questionnaires were a) organization (p=0.004; (median (range) 3 (2-5) compared with 5 (3-5)) b) knowledge is up-to-date (p<0.005; (median (range) 3 (2-4) compared with 4 (3-5)), c) discussion related to the problem (0.01; (median (range) 3 (1-4) compared with 4 (3-5)) and d) notice of the meeting (p< 0.026; (median (range) 3 (2-4) compared with 4 (2-5)),
Conclusions: This study showed that specific actions can improve the educational quality of the morbidity mortality meeting.

The effects of 2% and 4% sevoflurane in oxygen and nitrous oxide for induction of anaesthesia in 60 unpremedicated elderly patients was compared to those obtained during an intravenous Thiopentone induction. Intravenous induction induced anaesthesia in 27 +/- 5 seconds, significantly faster than a 2% or 4% sevoflurane induction (109 +/- 36 and 71 +/- 24 seconds respectively). One patient in both the thiopentone and 2% sevoflurane groups, and 2 patients in the 4% sevoflurane group coughed during induction. The postinduction reduction in mean arterial pressure was greatest in the thiopentone group followed by the 4% and the 2% sevoflurane groups. Heart rate changes were minimal in all groups. We conclude that 2% or 4% sevoflurane offered suitable conditions for induction of anaesthesia in the elderly with minimal cardiovascular derangement.
Intra-umbilical injection of oxytocin has been used to hasten placental separation in retained placenta. A randomised controlled trial was done on 35 consequent women who fulfilled the criteria for retained placenta at the Department of Obstetrics & Gynaecology Ipoh Hospital. Nineteen patients who were recruited into the study group received intraumbilical injection of 301U oxytocin in 27mls saline. Another 16 patients who were in the control group received 30mls of 0.9% sodium chloride (placebo). The primary outcome measured was the need for manual removal of placenta (MRP). Nine out of the 19 patients in the oxytocin group required MRP while 10/16 in the control group required MRP. There was a 24% reduction (95% C.I. 0.41 to 1.39) in the need for MRP in the study group compared to the saline group. our results indicate that intra-umbilical vein injection of oxytocin is not clinically useful for the removal of a retained placenta.
Vaginal hysterectomy for the large uterus is seldom performed in Malaysia. The traditional operation is abdominal hysterectomy. This is a personal series of vaginal hysterectomies for enlarged uterus of more than 12 weeks size (>280g) carried out in a private hospital between 1/1/97 to 30/9/2000. A total of 40 cases were done with the weights of the uterus ranging from 290g to 790g. The mean weight of the uterus was 434g. The average operating time was 92.1 min. The complications were minimal with 2 cases of blood transfusion for intra-operative hemorrhage, 1 case of fever and 1 case of bladder perforation. This series demonstrates feasibility and safety of the operation. The excellent recovery due to the absence of an abdominal scar should be a strong incentive for specialists to learn the skill.
The results of a prospective study of 94 patients with history of ear, nose or aerodigestive tract foreign bodies were analysed. Sixty six to 94% of patients presented within 24 hours to a primary care doctor, 80 to 94% was referred to the ENT Department within 24 hours and 89 to 93% of patients had their foreign bodies removed within 24 hours. Overall, 58% of aural foreign bodies, 67% nasal foreign bodies and 94% of aerodigestive tract foreign bodies were removed within 48 hours of insertion. As a result of the prompt removal of foreign bodies in the majority of patients, no significant complications occurred. Foreign bodies in the aerodigestive tract tend to present earlier and more promptly removed compared with ear and nose foreign bodies. There was a significantly higher proportion of foreign body in the right ear and nostril compared to the left.
Melioidosis is a potentially deadly infection that can affect any organ system. Reports of melioidosis of the ENT/head and neck region are relatively uncommon. Four cases are presented: (i) parotid abscess evolving into necrotising fasciitis, (ii) acute sinusitis and parapharyngeal cellulitis resulting in upper airway obstruction, (iii) acute suppurative lymphadenitis (iv) and chronic suppurative otitis media causing meningoencephalitis. Three of the four cases are believed to be unique, as a literature review of melioidosis in ENT/head and neck is also presented. Some practical issues of management are also discussed. Not suspecting melioidosis does not change contemporary empirical broadspectrum antibiotic therapy. The value of suspicion or on confirmation of diagnosis lies in anticipating and planning for rapid change.
A prospective study of 102 children with bacteriologically confirmed typhoid fever, admitted to Hospital Universiti Sains Malaysia over 5 years was conducted. The average age at presentation was 91.3 (range 6 - 159) months. Fever (900%), abdominal pain (56%) and diarrhoea (44%) were common symptoms. Findings included: hepatomegaly (85.3%), splenomegaly (27.5%), anaemia (31%), leukopenia (15%). thrombocytopenia (26%), positive Widal (62.5%) and Typhidot test (96%). Patients were treated with ampicillin (n = 54) or chloramphenicol (n = 49) and 1/3 developed complications like hepatitis (n = 19), bone marrow suppression (n = 8) and paralytic ileus (n = 7). A patient with splenomegaly, thrombocytopenia or leukopenia was at higher risk of developing complications.
A total of 1,134 finger-pricked blood samples were collected from residents of Setiu, Terengganu. A drop of blood was used to make thick blood smear and about four drops were used for obtaining serum. The smears were stained and examined by the State Vector Control Unit in Kuala Terengganu, while the serum samples were tested for specific IgG4 antibodies to a novel recombinant antigen using Brugia-Elisa. Prevalence of filariasis in these areas were found to be 0.26% (3/1,134) using thick blood smear examination and 2.47% (28/1,134) using Brugia-Elisa, thus demonstrating the greater sensitivity of the latter test. In addtion, Brugia-Elisa showed a high level of specificity (97.8%, 1,106/1,131) when compared to thick blood smear examination.
Infantile myofibromatosis (IMF) is a rare tumour with a wide spectrum of disease activity ranging from a solitary cutaneous nodule through to a multicentric form with widespread visceral involvement. It is characterised by its unique ability to spontaneously regress and has a typical histological appearance of actin-positive fibroblasts arranged in whorls or fascicles and vessels in a pericytomatous pattern. A male infant with multiple lesions involving the subcutaneous tissue and bone from birth is described and followed-up for two years. Treatment of IMF is dependent on the location of the tumour/s with surgery or chemotherapy reserved for rapidly progressive or symptomatic disease. However, due to the low rate of recurrence and the possibility of spontaneous tumoral regression, therapeutic abstention, as practised in our patient, is justified.
A case of non-recurrent laryngeal nerve is reported. The non-recurrent laryngeal nerve was found on the right side and was not associated with any vascular abnormalities. The anatomy and surgical implication of this rare condition is discussed
A fulminant clinical presentation with high fever and hepatosplenomegaly, together with a course of worsening pancytopenia, coagulopathy and liver failure, is suggestive of the haem syndrome (HPS). Bone marrow examination is diagnostic. We present 3 cases of HPS associated with different aetiologies including acute Ebstein Barr virus infection, T cell lymphoma, and malignant histiocytosis. In all the cases, the diagnosis was made late and the patients succumbed before definitive therapy could be administered.
In the setting of transplantation and chronic hepatitis B viral infection there is a unique histological feature termed cholestatic fibrosing hepatitis. The use of nucleoside analogues in the treatment of this condition has been successful. We describe a case of cholestatic fibrosing hepatitis, which occurred after intense immunosuppression for graft versus host disease in a patient with bone marrow transplantations. She was commenced on lamivudine therapy and showed good clinical, biochemical and virological response. However she succumbed due to sepsis.
Hantaviruses are primarily rodent-borne and transmission is by inhalation of virus-contaminated aerosols of rodent excreta, especially urine and saliva. The genus Hantavirus, family Bunyaviridae, comprises at least 14 serotypes and the symptoms of clinical illness range from mild fever to severe hemorrhagic manifestations with renal complications. Many countries in Southeast Asia are unaware of the importance of hantavirus infections and give them low priority. Malaysia, like other countries in the region, has conducted very few studies on the epidemiology of hantaviruses - and even these were conducted in the 1980s. Using a more extensive range of hantavirus antigens, we conducted a seroprevalence study of rodents and humans and found further evidence of hantavirus infections. Moreover, the data from the antibody profiles strongly suggest the presence of different hantaviruses at the study sites.
