Moraxella catarrhalis has gained reputation as a pathogen in the lower respiratory tract especially in patients with underlying chronic lung diseases. It is considered significant when isolated from sputum specimens of adults with respiratory tract infections. A study was carried out to determine the prevalence of Moraxella catarrhalis isolated in sputum specimens and beta-lactamase production of these isolates. Sputum specimens sent to the Bacteriology division, Institute for Medical Research from April 1990 until April 1993 were screened for Moraxella catarrhalis. A total of 1678 sputum specimens were processed and Moraxella catarrhalis was isolated from 15 (0.89%) of the sputum specimens. Six out of 15 (40%) were isolated from patients with chronic lung disease. Eight out of 15 (47%) were beta-lactamase producers. Moraxella catarrhalis isolated in good-quality sputum must not be disregarded and should be looked for especially in patients with chronic obstructive pulmonary disease. Beta-lactamase production should be tested on all isolates so that appropriate treatment can be given. All the isolates in this study were sensitive to cotrimoxazole.
In a study of 1,002 consecutive Malaysian male newborns, 48 (4.8%) were found to have undescended testes (UDT). The rate and laterality of the UDT were associated with lower birth weight (P < 0.001) and prematurity (P < 0.001). Boys with UDT were also more likely to have other congenital abnormalities of the external genitalia, the commonest being hydrocele. No correlation between UDT and maternal age, birth order, social class, or mode of delivery was demonstrated in this study. Although 26/34 (76.5%) of UDT achieved full spontaneous descent by 1 year of age, 1.1% of all infants whose testes remained undescended required regular long-term follow-up with surgical referral and correction at an appropriate time. A premature infant with UDT is more likely to achieve full testicular descent at 1 year of age than a term infant.

A case of severe bronchospasm occurring during epidural anaesthesia in a patient undergoing Caesarean section is described. The aetiology of the bronchospasm may have been related to sympathetic nervous blockade allowing unopposed parasympathetically mediated bronchoconstriction.
A study was undertaken to determine the assessment and management of adult asthmatic patients presenting to the Accident and Emergency department. The records of 50 consecutive adult asthmatic patients presenting to A & E with acute bronchial asthma between June 1993 to April 1994 were reviewed. Patients were also interviewed on their subsequent visit to hospital. Observations and measurements used to assess the severity of asthma were recorded with variable frequency--cyanosis 8%, inability to speak 2%, chest auscultation 64%, heart rate 10%, blood pressure 6%, respiratory rate 4%. The failure to record more objective measurements of severity of asthma and in particular extent of airflow obstruction is cause for concern. The drugs used to treat acute asthma in order of frequency were Beta agonists by nebuliser, 49 patients; intravenous aminophylline, 8 patients; and intravenous corticosteroids, 6 patients. 15 patients were admitted to the medical ward. The decision to admit patients appeared to be due to a lack of symptomatic improvement after treatment. Of the 35 patients who were discharged from A & E, 13 (37%) had an acute relapse within 10 days. None of the patients on discharge from A & E were given a short course of oral steroids or were advised an increase in steroid inhaler therapy. There was therefore a gross underuse of corticosteroids.

A 43-year-old lady with long standing non-insulin dependent diabetes mellitus on glibenclamide presented with cholestatic liver disease. Initially she was thought to have developed primary biliary cirrhosis (PBC). When she made a spontaneous recovery following the withdrawal of glibenclamide, it became obvious that the patient had been suffering from drug-induced chronic cholestasis (DICC). The subtle differences between PBC and DICC are highlighted.
Acute infective sacro-iliitis is a rare condition. Though gonococcal arthritis is not uncommon, this organism does not appear to have been isolated from the sacro-iliac joint. The first proven case of gonococcal sacro-iliitis is reported here. Difficulties in correct diagnosis of infective sacro-iliitis are highlighted. Management of gonococcal sacro-iliitis is described. With the increase in number of gonococcal infections, a case can be made for routine culture of joint material N. Gonorrhoeae in cases of septic arthritis in patients at high risk.
A typical case of chronic pericardial effusion resulting in cardiac tamponade is presented. A pericardiocentesis was done for diagnosis and drainage, followed by a pleuro-pericardial window as definitive therapy. The minimal cumulative dose expected to produce pericardial disease is about 4000 rads, and the disease usually manifests within 12 months of such radiation exposure, as in this patient. It is concluded that for symptomatic pericardial effusions, available evidence justifies a subtotal pericardiectomy, a window procedure being reserved to tide over ill patients as in this patient. No strong evidence exists for the efficacy of steroid therapy; such therapy is reserved for asymptomatic mild effusions, which may also resolve spontaneously.
Australia will fund 23 new HIV-AIDS projects in Southeast Asian countries, the government announced. "Asia is predicted to be the major growth area for human immunodeficiency virus (HIV) infections over the next decade, " Minister for Development Cooperation Gordon Bilney said. "These projects, worth some $4.35 million over three years, will help meet the challenge of preventing the spread of the disease in the region." The projects--in Thailand, Vietnam, the Philippines, Indonesia, Malaysia and Cambodia--emphasize education and prevention activities as well as programs which focus on the care and support of people living with HIV, Bilney said. He also said a variety of Australian and overseas organizations will implement the projects, many of which will feature the significant involvement of communities at risk and people with HIV. "It is in keeping with the fundamental spirit of the aid program that we should seek to share this expertise with our neighbors in the region." Bilney said one Australian success story--the creative "Streetwize comics" (publications in Australia which help street kids and under privileged kids understand HIV/AIDS problems)--will be piloted in Vietnam in conjunction with the Vietnam Youth Federation. He said Vietnamese staff will be trained in the production of a series of bilingual mini-comics on HIV-AIDS prevention for youth. "This project will receive funding of $187,500 over three years," Bilney said. Bilney said the projects would help minimize the individual and social impact of the epidemic in the targeted countries.
Forty-eight patients treated surgically for chronic subdural hematoma in General Hospital Kuala Lumpur were studied retrospectively. The clinical presentations were insidious and nonspecific. A high clinical index of suspicion for this disease is required. Diagnosis is confirmed by CAT Scan of the brain with or without cerebralangiography. Treatment consists or burr-holes and drainage
A case of acute appendicitis occurring in a 10- month-old infant is reported. The difficulties of an early preoperative diagnosis are highlighted. Perforation has usually occurred on presentation. However, prognosis may not necessarily be poor if active measures are instituted soon after perforation. The importance of active and aggressive preoperative resuscitation with fluids and electrolyte and intravenous antibiotics is stressed.
A case of Acute Post Exertional Anterior Compartment Syndrome of the leg, seen five days after the onset of symptoms is presented. Decompression with delayed closure was done. There was only sensory recovery. However functional recovery at one year was good. Acute Post Exertional Compartment Syndrome cases are diagnosed late due to the lack of awareness, the paucity of radiological features, and the presence of intact peripheral pulses. A review of the literature revealed no previous documentation from South-East Asia.
Two outbreaks of mushrooms poisoning involving 3 and 9 soldiers respectively with one death on 9 March 1980 in Perak are described. The symptoms were compatible with muscarine [a neurotoxin] poisoning which was detected in the stomach contents of the dead soldier and the mushrooms consumed by one group.
This paper presents a case report of a primary lymphoma of the appendix as the underlying cause of acute appendicitis. As in previous reported cases, diagnosis can only be made intraoperatively followed by a proven histopathological picture as they present with an acute surgical abdomen.
Acute nonspecific carditis with advanced heart block is rare. We observed nine cases with complete heart block and one with Mobitz type II block over an eight and a half year period. Temporary cardiac pacing was instituted in all while permanent pacing was required in six patients. No death was recorded.
In a prospective study of 300 infants with acute gastroenteritis 150 infants had enteropathogens in the stools, 58 being due to rotavirus, 130 to adenovirus, 32 to Sahnonella, 18 Shigella and 29 E. coli. Hypernatraemic dehydration was present in 11% and acquired carbohydrate intolerance in 30% of the infants. Protracted diarrhoea was observed in 8% of infants and was commoner in the bacterial than viral group. The study shows that clinical features and simple blood tests cannot be used as reliable indices of predicting the aetiology of AGE. Despite the diverse aetiology of acute gastroenteritis, rehydration by the oral or intravenous route remained the mainstay of therapy.

The dynamics of the transmission of subperiodic Brugia malayi in a typical endemic area in Malaysia was studied over a period of 4 years. Mass chemotherapeutic control with diethylcarbamazine citrate was found to be inefficient, new cases being detected even after the fifth treatment cycle of 6 mg/kg X 6 days per cycle. This is in marked contrast to the situation in periodic b. malayi areas where mass treatment efficiently controlled the infection. The disparity in results in these two areas is attributed to zoonotic transmission of subperiodic B. malayi from non-human primates where a mean infection rate of 76.3% was found.
A prospective study of acute nephritis in children was conducted at the Universiti Sains Malaysia Hospital, Kubang Kerian between July 1987 and June 1988. One hundred and twenty four children were admitted with acute glomerulonephritis. The aim of the study was to determine the clinical pattern of the nephritis as well as its aetiology. The majority of our patients came from the lower socio-economic group and 54% of the families had incomes below the poverty line. Preceding skin infection was much more common than throat infection. The children showed a high incidence of complications: severe hypertension (43.6%), hypertensive encephalopathy (11.3%), clinical pulmonary oedema (36.3%), severe azotaemia (10.5%), and prolonged gross haematuria (13.7%). By using immunologic indices such as ASOT, anti-DNase B and complement 3, it was concluded that 121 of the 124 patients had post-streptococcal nephritis.
