The uroflow and pressure-flow data of 67 men aged 65 years or more were compared. At best, the uroflow study applying the Liverpool nomogram (25th percentile) and Bristol nomogram (OSD) diagnosed bladder outlet obstruction with sensitivity of 62.5% and 62.5% and specificity of 48.8% and 74.4% respectively. Using the 50th percentile of the Liverpool nomogram as the cut-off resulted in a negative predictive value of 100.0% allowing about 10% of men to have this diagnosis ruled out. We conclude that the uroflow study is inaccurate in diagnosing bladder outlet obstruction in elderly men. However, it can be used to rule out this condition in the small subset of men with maximum flow rates above the 50th percentile of the Liverpool nomogram.

A prospective observational study was carried out at the Emergency Department, Hospital Kuala Lumpur to determine the proportion of accidental head injury among children and the circumstances of injury. The study was carried out from November 1993 to January 1994 on all children below 14 years who presented to the Emergency Department with accidental head injury. Accidental head injury made up (4.75%) of all cases seen at the Casualty Department. The ratio of boys to girls was 2:1. The mean age of head injured children was 5.2 (S.D. 3.63) years. The leading cause of head injury was fall (63%) followed by road traffic accidents (RTA) in (30.7%) while the rest were due to 'impact' (injury caused by flying object or missiles) injuries. More than half (54.4%) of those injured in RTA were pedestrians. Pedestrian injury was particularly important in the 5-< 14 years age group, where adult supervision was lacking in two thirds of the children. None of the patients who were involved in vehicle-related injuries had used a suitable protective or restraining device. All three patients who died were from this group. This study emphasises the need for stricter enforcement of laws related to the use of protective devices and measures to decrease child pedestrian injury. The issues of lack of adult supervision, both in and outside the home need to be addressed.

This paper reports the characteristics and psychopathology of alcohol dependents with alcohol induced psychotic disorder admitted to the Seremban Hospital. The method is that of a case study of all alcohol dependents with alcohol induced psychotic disorder admitted to the Psychiatric Ward, Hospital Seremban over 3 years (1993-1995). There were 34 subjects, 30 Indians, 3 Chinese and 1 Malay with a mean age of 43 years. 32 were men and predominantly of Social Class IV and V (91%). They had a mean duration of drinking of 14.2 years and had a mean weekly consumption of 69.5 units of alcohol. There was a family history of alcohol dependence in (44%). The majority (68%) consumed samsu with beer the second choice. Auditory hallucinations (26) and delusions (16) were common while visual hallucinations (3) and depression (2) were less frequent. Speech disorder occurred in 4 subjects. 2 developed delirium tremens and 1 died. Liver function test was normal in 55%. All except the death from delirium tremens responded to treatment with a combination of anxiolytics, thiamine and antipsychotics and were rapidly discharged. The mean stay was 7 days. However, (68%) did not return for follow up and only 4 were abstinent from alcohol at the time of follow up.
An approach to cannulate right internal jugular vein in neutral head position is described for situations where head rotation and extension are contraindicated. Venous puncture was made immediately lateral to the carotid artery at the level of cricoid cartilage and directed caudad. In 40 patients studied, the right internal jugular vein of 97.5% of the patients were successfully located by the finder needle. The mean (SE) number of puncture attempts to locate the vein was 1.3 (0.1) per patient. In 72.5% (29 patients), the veins were located exactly at the predicted point after the first attempt. However the overall success rate for cannulation by the angiocath cannula was 87.5% and short term complication rate was 5.0%. We conclude this technique is a reliable, safe alternative for central venous access, especially in patients where cervical spine movement is contraindicated or restricted.
Malaysia's workforce presently includes 13% foreigners most coming from the neighboring ASEAN-countries. No data of the prevalence of psychiatric disorders amongst this population is currently available.
A cross-sectional prevalence study amongst a nursing home elderly population was carried out at Rumah Sri Kenangan, Seremban, Negeri Sembilan between June 1995 until June 1996. A total of 204 cases of 60 years and older were examined in order to determine the ocular morbidity amongst them. It was found that 47.5% had low vision and 19.1% were legally blind. Cataract was found to be the leading cause of low vision and blindness occurring in 81.4% and 74.3% respectively. Glaucoma occurred in 1% of those who had low vision and none due to macular degeneration or diabetic retinopathy. The magnitude of visual impairment and blindness in this nursing home is high but is preventable and avoidable.
One hundred and twenty specialists from the Ministry of Health, the Universities and the private sector provided information on 4,802 patients seen over a total of two hundred and forty working days. This information was used to classify the patients into four categories based on a disease complexity classification. Each specialist's perception on the appropriateness of utilisation of his expertise was obtained. Complex cases requiring specialist expertise in management made up 69.8%, 73.5% and 19.1% of the cases of the Ministry of Health, University and private sector specialists respectively. Underutilisation was most marked with paediatricians and obstetricians in the private sector. The Specialist Register, the Programme for Accreditation of Hospitals and a National Health Financing Plan can be used to influence positively the case-mix of specialists.

To determine the clinical and radiological features of the patients who were found to have cavum septum pellucidum (CSP) on the cranial computerized tomographic (CT) scans.
Thirty-six patients with lupus nephritis (LN) attending the Nephrology Clinic, Hospital Kuala Lumpur were studied for the prevalence of anticardiolipin antibody (ACA) isotypes (IgG and IgM) and other associated antibodies, antinuclear antibody (ANA) and anti-ds DNA antibody and to determine the possible association between serological and clinical parameters. The study population consisted of 20 (55.6%) Malays, 15 (41.7%) Chinese and 1 (2.8%) Indian with a mean age of 31.4 +/- 11.3 years, range 14 to 60 years. The female to male ratio was 11:1. The average time between diagnosis and blood sampling was 4.4 years (range 0.25 to 15 years). Increased ACA levels were found in 20 (55.6%) patients where raised IgG ACA and IgM ACA were observed in 20 (55.6%) and 2 (5.6%) cases respectively. ANA and anti-ds DNA antibodies were detected in 22 (61.1%) and 4 (11.1%) individuals respectively, with the majority (82%) showing a speckled pattern of nuclear staining. However, neither the IgM ACA nor IgG ACA showed any significant association with thrombosis or any other clinical parametres. Our preliminary study indicates that ACA is a frequent finding in lupus nephritis and that the IgG isotype is more prevalent.

Secondary intraocular lens implantation after cataract surgery done in University Hospital between 1983 to 1993 were reviewed. Thirty three patients (37 eyes) underwent secondary intraocular lens implantation during this period. Twenty four eyes had secondary anterior chamber lens implantation while 13 had posterior chamber lens implantation. There was no case of secondary posterior scleral fixation lens implantation. Visual acuity of 6/9 or better was seen in 25 of 37 eyes (67%) in the series. Eyes seeing as good or better than before secondary implantation procedure were noted in 34 of 37 eyes (92%). Vision of 6/9 or better was seen in 9 of 13 eyes (70%) with posterior chamber implants and 16 of 24 eyes in (67%) with anterior chamber lenses. Complications including bullous keratopathy, uveitis and glaucoma were seen with anterior chamber implants of the rigid type resulting in poorer visual acuity than before the secondary procedure.
Coeliac plexus block has been described more than seventy years ago and is widely used for chronic pain management in upper visceral malignancies. The technique described here is a posterior approach using CT scan guidance with absolute ethyl alcohol. A case illustration of a patient with carcinoma of pancreas managed with coeliac plexus block for pain control is presented.
A gravid patient with fetal supraventricular tachycardia is presented. A review of this rare condition and the present recommended mode of therapy are discussed.
Three children aged 3-11 years had ultrasonography of the urinary tract for the investigation of dysuria and haematuria. A bladder mass was seen in these 3 children. One child had computed tomography scan, cystoscopy and bladder biopsy because rhabdomyosarcoma was considered. The biopsy revealed an inflammatory process. The urine culture of the other 2 children revealed E. coli. On ultrasonography, the inflammatory mass may appear homogeneously hypoechoic or may contain moderate level echoes. The mucosal surface of the mass may be smooth or lobulated. It is important to consider an infective cause for a bladder mass in children because computed tomography, cystoscopy and biopsy may be avoided.
A patient who was referred to the eye department for routine ocular assessment prior to commencement of antituberculous therapy was found to have periphlebitis in both eyes despite being visually asymptomatic. Fluorescein angiography confirms the presence of vasculitis without any retinal oedema or areas of non-perfusion, which may sometimes accompany the condition. Within 2 months of systemic treatment, the ocular signs regressed without any permanent effect on vision. This case highlights a rare ocular complication associated with systemic tuberculosis which fortunately did not result in loss of vision due to prompt treatment.
We present a case of rare pitfall in the diagnosis of an oesophageal foreign body due to the calcified vertical plate of the cricoid to highlight the need to be aware of this entity to avoid unnecessary morbidity.
Infectious agent(s) causing the fatal Sarawak acute childhood viral infection (SACVI) has not been identified. In the present study, results indicating that inocula prepared from the fatal cases of SACVI induced apoptosis in Vero cell cultures are presented. These findings suggest the possible involvement of apoptotic cellular responses in SACVI.

Exanthem subitum (ES) is a common childhood exanthematous disease. In a recent study of ES due to human herpesvirus 6 (HHV 6), we isolated human herpesvirus 7 (HHV 7) from the peripheral blood mononuclear cells (PBMC) of a seven month-old infant with typical symptoms of ES. The identity of the virus was confirmed by indirect immunofluorescence using HHV 7 specific monoclonal antibody and by amplification of the HHV 7 specific genomic sequences using the polymerase chain reaction (PCR). Paired serum samples from the infant showed serological conversion to the isolated virus. The clinical manifestations of ES in this infant appeared to be milder than the classical ES due to HHV 6.
The Working Party Report on the Management of Helicobacter pylori serves as a clinical practice guideline for Malaysian doctors. H. pylori is not uncommon in the Malaysian population. Marked racial differences and the consistently low prevalence rates amongst Malays are noted. The working party recommends that if endoscopy is to be performed, a rapid urease test should be used for diagnosis. Where suspicion of the infection is strong and the urease test is negative, histology should be performed on gastric biopsies. Culture should be used to monitor resistance patterns to antibiotics and regional laboratories should assume this responsibility. The urea breath tests are highly accurate tests for diagnosis of H. pylori but is as yet not widely available in Malaysia. The working party strongly recommends that all peptic ulcer patients infected with H. pylori whether active, in remission and complicated ulcers should be treated for the infection. Patients with low-grade gastric mucosal lymphoid tissue lymphoma should also be treated for H. pylori infection. It is considered advisable that patients on long term nonsteroidal antinflammatory drug (NSAID) treatment with a history of peptic ulcers or dyspepsia and patients following resection of early gastric cancer or those with a family history of gastric cancer should also be tested and treated for H. pylori. The working party recommends, as first line treatment a 7-day combination therapy of a proton pump inhibitor, clarithromycin and metronidazole or amoxicillin. High metronidazole resistance rates locally may adversely affect regimens containing the antibiotic. It should also be noted that regimens that yield lower eradication rates may result in higher long term expenditure.
