This was a prospective survey using a standard questionnaire to determine the prevalence of use of oral traditional medicine and food supplements among patients with rheumatic diseases. Among the 141 patients surveyed, we found that 69% of the patients were consuming food supplements, 35% were using traditional medicine and 45% had used traditional medicine at some time or other. Females were more likely to use food supplements (P < 0017); especially among those with higher education (p < 0.036). There was no statistical difference between those who had ever consumed compared to those who never used traditional medicines. The Chinese were more likely than others to be using traditional medicine (p < 0.007). Vitamin C and B were the most commonly used food supplements. More than two thirds of the patients obtained their traditional medicine from non-medical personnel. More than half of them used 2 or more types of traditional medicine for more than two months. Spending on traditional medicine was noted to be modest with 73% spending less than one hundred ringgit a month for their traditional treatment. Doctors need to be aware of the possible interactions between these 'self-medications' and the conventionally prescribed medication.
The best therapeutic choice in the treatment of lupus nephritis remains open to debate. In addition, there have been little data on the treatment of lupus nephritis in Asian patients. The objective of this study was to look at the response rate and complications of treatment given for lupus nephritis in a group of South East Asian patients with systemic lupus erythematosus (SLE). This was a retrospective, cross-sectional study of 103 patients with lupus nephritis. Detailed analysis was done on 58 patients with Class IV disease. The median time to remission was 12.1 months for azathioprine (AZA), 15.01 months for oral cyclophosphamide (CPM) and 15.25 months for intravenous (i.v.) CPM. The percentage of patients achieving remission after the first course of treatment was 42.9% with AZA, 83.3% with oral CPM and 90.9% with i.v. CPM. Overall, 41/58 (70.7%) of patients went into remission following the first course of treatment. Seventeen (41.5%) subsequently relapsed, requiring a second course of treatment. Fifty-two (50.5%) of all patients had drug-related complications from their treatment. The most frequent complication for the group was amenorrhoea (23.3% of all patients, 40% of those who had CPM previously), which was significantly more frequent in patients given CPM. In conclusion, more patients achieve remission when treated with CPM compared with AZA alone but this is associated with a higher complication rate, especially amenorrhoea.
A cross-sectional study was carried out in University of Malaya Medical Centre, Kuala Lumpur. Blood samples from 100 HIV-infected patients and 203 Healthy Blood Donors (HBD) were collected and anti-Toxoplasma antibodies were detected by using conventional ELISA. The seroprevalence of toxoplasmosis in HIV/AIDS and Healthy Blood Donors were found to be 21% and 28.1% respectively. There was no significant association between the seroprevalence of toxoplasmosis and various possible risk factors i.e. contact with cat, consumption of undercooked meat and history of blood transfusion in both groups. No significant differences between Toxoplasma seroprevalence in HIV/AIDS and Healthy Blood Donors in association with presence of single or multiple risk factors were found. The mean CD4 count among HIV/AIDS patients in this study was 202.23 cell/cumm. There was no significant association between CD4 count and seropositivity for Toxoplasma antibodies in HIV/AIDS patients.
Objective: To assess if children with Down's Syndrome have a higher prevalence of otological abnormality compared to their normal counterparts in Malaysia.
Methodology: Thirty children with Down’s Syndrome and normal children underwent otoscope ear examination and impedance test in the ENT outpatients clinic in University Hospital Kuala Lumpur, Malaysia.
Results: The study showed that children with Down’s Syndrome had higher ontological disorders. Forty four percent had impacted wax compared to 14.4% in normal children. Twenty one percent of ears in the study group had refracted drums compared to 6.6% of control. Fifteen percent of ears in the study group had middle ear effusion compared to 3.4% in controls, 55% had a type B tympanogram compared to 8.3% in controls and 73.4% had auditory canal stenosis compared to 14.4% in controls.
Conclusion: Children with Down’s Syndrome thus have a higher incidence of ontological disorders.

A survey was conducted in December 1995 to study car occupant restraint usage in Selangor. A total of 1082 car occupants were observed in 536 cars. The results of the study shows that only 57.3% of the car occupants observed were protected by any form of restraints. Most of the cars (99.8%) examined had front seat belts but only 44.2% had rear seat belts. Only 0.6% of the cars were found to have child restraints in the cars. 80.2% of drivers used restraints and only 65.4% of front seat passengers used any forms of restraints. In the case of the rear seat passengers, only 0.42% used an available restraint. More people in the urban areas (84.42%) than in the rural areas (66.51%) used seat belts. Usage of seat belts by car drivers influenced the use of seat belts by front seat passengers. Type of seat belts fitted was associated with usage rate. It is sad to note that 21.9% of the drivers used seat belts incorrectly.
Upper respiratory tract infections are the commonest reason for consultation in primary care. Group A beta-haemolytic Streptococcus (GABHS), the most important bacterial pathogen in this condition, can be cultured from about 30% of patients, more so in children than adults. Clinical features that are predictive of positive GABHS culture are absence of cough, fever, cervical adenopathy, tonsillar enlargement and tonsillar exudate. Use of a sore throat score can help in the detection of streptococcal throat infection. Symptomatic therapies which are useful include anticholinergic, antihistamine, decongestant, humified hot air and Vitamin C. Antibiotics are universally over-prescribed in this condition as a result of high patient expectation and faulty clinical decision making. Oral Penicillin V for 10 days is the drug of choice. Effective intervention to reduce inappropriate antibiotic prescription probably require a multifaceted approach targeted at both the patients and the prescribers.
From 1982 till 1999, our department performed a total of 2970 heart valve replacements--92% of which were with mechanical heart valves. During this period, there were 8 patients who came to our department with mechanical heart valve obstruction. All these patients presented with signs of heart failure or compromised haemodynamic. Confirmatory tests included transthoracic or transoesophageal echocardiography and cine fluoroscopy. Seven patients were operated upon urgently. Four of the patients had valve thrombosis. The time interval between the initial implantation and presentation varies from 4 months to 11.3 years. Six of the seven patients who were operated on recovered well from the surgery.
Objective: To study the prevalence of symptomatic BPE among Malaysian men age 50 and above attending prostate health awareness campaign and to identify differences in prevalence between different ethnic groups residing within metropolitan Kuala Lumpur.
Materials and Methods: Demographic data and the completed International Prostate Symptom Score (IPSS), maximal uroflow rate (Qmax) and prostate size of volunteers, aged 50 and above, who attended the prostate health awareness campaign were analyzed. Subjects with known prostate diseases or prostate surgery, bladder disorders and neurological disorders were excluded.
Results: 2086 volunteers attended the campaign. 575 men fulfilled the inclusion criteria and their demographic data, IPSS; peak flow rate and prostate volume were analysed. Overall, 18.9% and 39.6% of the men were severely and moderately symptomatic, respectively. The prevalence of moderate to severe lower urinary tract symptoms (LUTS) in Malays, Chinese and Indians were 70%, 59% and 50% respectively (p=0.004). The commonest bothersome symptoms were nocturia (56%), frequency (50.4%) and sense of incomplete voiding (43.5%). The mean peak flow rate of the subjects was 15.4ml/s. 20.9% and 55.2% of the subjects had peak flow less than 10ml/sec and 15ml/sec respectively. The mean prostate size was 25.1cc. There is no significant difference in term of maximal flow rate and prostate size among Malays, Chinese and Indians in Malaysia. A good correlation was found between the total symptom score and the single disease-specific quality of life question (r=0.69, p<0.001). The correlation between IPSS and peak flow rate (r=-0.22, p<0.001) and prostate volume (r=0.11, p=0.009) was weak. There was no correlation between IPSS and age (r=0.06, p=0.17). The prevalence of symptomatic benign prostate enlargement (BPE) was 39.3%. The prevalence increased 8% per decade from 41.7% for men aged 50 to 59 to 65.4% for men aged 70 or more. There is no significant difference in prevalence of symptomatic BPE among the three ethnic groups. The prevalence of BPO was 15.8%.
Conclusion: The correlation between symptom score, maximal flow rate and prostate size was poor and one cannot predict the value of one parameter by knowing one or more of the other parameters. There is a high prevalence of LUTS suggestive of benign prostatic obstruction in the apparently healthy Malaysian aged 50 and above attending the prostate health awareness campaign.
DRE has been used as a diagnostic and screening tool for prostate cancer for decades. However these are based on Western data and its local applicability has yet to be verified. We held a Prostate Health Awareness Week in August 1998 and a total of 2086 men were screened. All men aged 50 years old and above were included for the study. The subjects were evaluated on DRE findings, PSA levels and if indicated a TRUS-guided biopsy results. We concluded that DRE per se might have limited role in the screening of prostate cancer in Malaysia. Screening using DRE and PSA combined are still recognized as the most cost-effective means. Neither DRE nor PSA alone has high enough specificity for diagnosis of prostate cancer cases. Combining DRE and PSA will definitely increase the specificity significantly.

We prospectively evaluated the effect of the treatment of lower urinary tract symptoms (LUTS) on sexual function. The patients were assessed by using the International Index of Erectile Function (IIEF-15) inventory at baseline and three months after medical (alpha-blockers) or surgical treatment (transurethral resection of the prostate, TURP). Following treatment, there were improvement in erectile function and intercourse satisfaction while orgasmic, overall satisfaction and sexual drive were relatively unchanged in the medication group. Patients who had surgical treatment suffered retrograde ejaculation, dissatisfaction in sexual intercourse and overall sexual satisfaction compared to patients who were on alpha-blockers.

An analysis of 105 consecutive patients with chronic hepatitis C at the gastroenterology outpatient's clinic in Hospital Kuala Lumpur was performed. The clinical, laboratory and virological data was prospectively recorded in the case notes and comprised of data on patient characteristics, risk factors, clinical features, laboratory features, virology screen and management. Chronic Hepatitis C cases accounted for 2.1% of the total number of cases seen at this clinic during the entire period. There were 78 (74%) males and 27 (26%) females. The ethnic breakdown consisted of Chinese (44.2%), Malays (39.4%), Indians (15.4%) and others (1%). There was higher male preponderance in all the ethnic groups. The main mode of transmission was blood transfusion comprising 51 patients (48.8%). A total of 35.2% of cases underwent treatment, of which a proportion had interferon monotherapy for 6 or 12 months and a subsequent group of naïve patients and non-responders underwent combination therapy with interferon and ribavarin.
This is a retrospective study of the annual mortality that occurred in the Department of Surgery, Alor Setar Hospital, for the years 1995 to 1997. This study looks at the number of admissions to the surgical wards and categorizes the causes of death. The annual mortality rates were 2.60, 2.89 and 3.25 per hundred admissions for the year 1995, 1996 and 1997 respectively. Head injury was the leading cause of death whilst sepsis and advanced malignancies second and third commonest causes. We hope that with the publication of these figures, we can initiate more studies to analyse similar local data.
This study aims to investigate the incidence and causes of hyponatraemia in hospitalised elderly patients. There was a total of 407 new patients. 55 (13.5%) patients were found to have at least one episode of hyponatraemia during their hospitalization. There were 58 deaths. Fifteen out of 55 (27.3%) patients who had hyponatraemia died compared to 43 out of 352 (12.2%) normonatraemic patients (chi-square significant, p < 0.01). The three most common causes of hyponatraemia were syndrome of inappropriate antidiuretic hormone secretion (SIADH), poor oral intake and diuretics. The two most common causes of SIADH were lower respiratory tract infection and stroke.
CU-acquired nosocomial infection (NI) remains one of the major causes of ICU mortality. This study presents the incidence of ICU-acquired nosocomial infection in ICU HUKM for the years 1998 and 1999, as part of the ongoing ICU-acquired nosocomial infection surveillance program. The overall incidence was 23%. The main types of NI was lower respiratory tract infection (15.3%), primary bacteraemia (8.1%), ventilator associated pneumonia (5.4%), urinary tract infection (2.0%), skin infection (1.6%) central venous catheter sepsis (1.2%) and surgical skin infection (0.8%). The overall culture positive nosocomial infection rate was only 12.1%, majority from the lungs (12.6%), blood (7.3%), skin swabs (2.0%), and urine (1.6%). The main gram-negative organism cultured was Acinetobacter sp. (19%) and Staph. aureus (8.5%) was the gram-positive organism. The overall ICU mortality rate was 27.5% of which 60.9% of patients who died were attributed directly to sepsis.
Sixty percent of open fracture wounds are contaminated at the time of injury. Despite that, the necessity for sequential multiple cultures and sensitivity studies for open fractures and their interpretation are still controversial. Predebridement, intraoperative, postoperative swabs and swabs in established infection for culture and sensitivity study were taken in 33 open tibial fractures over a 6 months period. 39.3% of predebridement swabs grew bacteria with the majority yielding gram-positive organism. None of the patients developed infection with similar organisms. 24.2% of the postoperative swabs grew bacteria, of which 75% were gram-negative. 50% of the patients with positive postoperative swabs developed infection. Thus, the role of sequential multiple cultures and sensitivity studies are not helpful in management of open fracture.
This is a retrospective study of the prevalence of Human Immunodeficiency Virus (HIV) positive mothers in two states in Malaysia i.e., Perak and Negeri Sembilan since the introduction of the HIV screening programme in antenatal mothers. The study period was from 1/9/97 to 1/9/99. A total of 29 HIV positive antenatal mothers were detected (21 from Perak and 8 from Negeri Sembilan) throughout the study period. Out of the 21 HIV positive mothers from Perak, 8 (38%) were foreign nationals whereas only 1 (12%) out of the 8 from Negeri Sembilan was a foreign national. The main risk factor identified in both the groups was multiple sexual partners. The vertical transmission rates for the patients from Perak were 14.2% and 37.5% in Negeri Sembilan. There was no significant short-term adverse obstetric outcome.
Hypertrophy of the inferior turbinates are the major cause of nasal obstruction. CO2 lasers have been used to reduce the size of the inferior turbinates over the last 20 years. However, the many techniques of delivery of the laser show that there is no one standard method reducing the size of the turbinates. We now describe how the laser can be applied directly to the turbinates using a handpiece with a special nasal tip, thus overcoming the disadvantages delivery via arthroscopic devices, microscopes and fibers. This technique is further enhanced by coupling it with Swiftlase which swirls the focused beam in a 3 mm spot thus ablating tissue more quickly. This procedure is done under local anaesthesia. The ablation of the anterior third of the inferior turbinates effectively overcomes nasal obstruction. This new method was compared to the more traditional submucus diathermy. 22 patients were subjected to laser treatment whilst 20 patients were subjected to diathermy. The outcome was evaluated subjectively by the patients themselves at 2 weeks, 3 months and 6 months. At the end of the study, the laser group reported a more significantly improved nasal airway (91% against 75%) and decreased rhinorrhea (72.7% against 35%) when compared to the diathermy group.
An analysis was done of available data from the Department of Statistics Malaysia, on the type of congenital abnormality contributing to death, to determine whether progress in health care over recent years was associated with any decline in mortality from congenital abnormality. A significant decline in death due to congenital abnormality was observed between 1991 and 1996. This was attributable to a decline in deaths due to congenital heart disease occurring because of improvements in cardiac surgical services for infants. In 1997 death due to congenital heart disease increased significantly. This could be attributed to improvements in the diagnosis of congenital heart disease in the neonate.
Dermatoglyphic is the study of the epidermal ridges and the pattern formed by them. It may be pointed out that genetic factors have a large share in determining the variations in dermatoglyphics. It is however, suggested by evidence that bipolar mood disorder factors are determined more by genetic factors than by the environmental factors. The experiment has been undertaken to look for the effects of the bipolar mood disorder on dermatoglyphics. The dermatoglyphic characteristics of subjects with bipolar mood disorder when compared with control group revealed significant differences. The radial loop were increased in bipolar mood disorder, but there were little changes in 'atd' angles between normal and bipolar mood disorder.
