Breast ductal carcinoma in-situ (DCIS) is increasingly being diagnosed as a result of screening mammography and better pathological recognition. With this and the rising breast cancer incidence in Singapore, DCIS is poised to become a bigger part of surgical practice. Principles of screening, diagnosis and management of DCIS have also been rapidly evolving. Against this background, a clinicopathological audit of recent cases of DCIS in our centre was performed.

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.
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.

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 authors made a 3-year retrospective study of cases of tubo-ovarian abscess surgically treated in KK Women's and Children's Hospital. In the period studied (1998 through 2000), there were 36 such cases. A total of 11 patients underwent laparoscopic treatment while 25 patients underwent laparotomy. The study demonstrates the differences in the patient profile and the short term morbidity in each mode of surgical treatment and the changing trends in the surgical treatment of tubo-ovarian abscess.
Diabetes mellitus is an important risk factor for the development of coronary artery disease. The presence of microalbuminuria, which indicates renal involvement in diabetic patients, influences the progression of coronary artery disease. New coronary risk factors such as C-reactive protein (CRP), Lipoprotein a [Lp (a)] and fibrinogen are increasingly being recognized as important cardiovascular prognostic factors. These new coronary risk factors could account for the worse cardiovascular prognosis in diabetic patients with microalbuminuria. Our cross sectional study was to compare the prevalence of elevated CRP and the levels of Lp (a) and fibrinogen between diabetic patients with microalbuminuria and those without microalbuminuria. Diabetic patients with overt coronary artery disease were excluded from the study. A total of 108 patients were recruited of which 57 patients had microalbuminuria and 51 were without microalbuminuria. There was no difference in the number of patients with elevated CRP between these two groups. There were also no significant differences in the mean values of Lp (a) and fibrinogen between diabetic patients with and without microalbuminuria. The inflammatory marker CRP and coagulopathy markers i.e. Lp (a) and fibrinogen seem not to be perturbed in diabetic patients with microalbuminuria.
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.

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.
Methicillin-resistant Staphylococcus aureus (MRSA) has been prevalent in our hospital over the last three years. Differentiation among MRSA strains by DNA typing in addition to antibiotic resistance pattern surveillance is crucial in order to implement infection control measures. The aim of this study was to characterize MRSA isolates from patients admitted to Hospital Universiti Kebangsaan Malaysia (HUKM) by phenotypic (analyses of antibiotic susceptibility pattern) and genotypic (PFGE) techniques to determine the genetic relatedness of the MRSA involved and to identify endemic clonal profiles of MRSA circulating in HUKM. Seventy one MRSA strains collected between January to March 2000 from patients from various wards in HUKM were tested for antimicrobial resistance and typed by pulsed-field gel electrophoresis (PFGE). Four major types of PFGE patterns were identified (A, B, C and D) among MRSA strains. Two predominant PFGE types were recognised, Type A (59.2%) and Type B (33.8%). Most of these strains were isolated from ICU, Surgical wards and Medical wards. MRSA strains with different PFGE patterns appeared to be widespread among wards. Strains with the same antibiotype could be of different PFGE types. Most of isolates were resistant to ciprofloxacin, erythromycin, gentamicin and penicillin. One isolate with a unique PFGE pattern Type D and susceptible to gentamicin was identified as a different clone. Some isolates obtained from the same patient showed different PFGE subtypes suggesting that these patients were infected/colonized with multiple MRSA strains. PFGE analysis suggests that MRSA strains with different PFGE types was propagated within our hospital. The relationship between antibiotic susceptibility and PFGE patterns was independent. The ability of PFGE technique in differentiating our MRSA strains make it a method of choice for investigating the source, transmission and spread of nosocomial MRSA infection, and thus an appropriate control programme can be implemented to prevent the spread of MRSA infection.
Atopic dermatitis is the commonest skin disease in children, causing psychological, social and functional disability to them and their families. This study assessed the family impact and quality of life using the translated Malay version of The Dermatology Family Impact (DFI) and The Children's Dermatology Life Quality Index (CDLQI) questionnaires. Seventy-two children, aged between 6 months and 16 years attending the Paediatric Dermatology Clinic at the Paediatric Institute and the Dermatology Department, Hospital Kuala Lumpur participated in this study. Thirty-nine patients (54.2%) were males and 33 patients (45.8%) were females. The median age of the patients was 74 months (Q1 6, Q3 104 months). The median age of diagnosis was 22 months (Q1 1, Q3 36 months). The median disease duration was 44 months (Q1 3, Q3 65). The severity of eczema was assessed using the SCORAD severity index (maximum score = 83). The median SCORAD (European Task Force On Atopic Dermatitis) score was 36 (n = 72, SD = 16.2). The majority of patients in this study suffered from moderately severe eczema (n = 40, mean, SCORAD = 29.3) followed by severe eczema (n = 27, mean SCORAD = 54.3). The mildly affected patients formed the minority group (n = 5, mean SCORAD = 9.0). The family impact was shown to be greater in severe atopic dermatitis compared to moderate atopic dermatitis (Anova, p = 0.02). The children's quality of life impairment was also greater in severe atopic dermatitis compared to moderate atopic dermatitis (Anova p = 0.08). This study confirms that quality of life and family impact are related to the severity of atopic dermatitis.
A cross-sectional study was conducted to determine the prevalence and type of respiratory conditions including asbestos-related diseases among Malaysian asbestos cement workers. The study population consisted of 1164 workers who had undergone medical surveillance from 1995 to 1997, including full history, physical examination, chest radiography and spirometry. More than half the male workers were smokers or ex-smokers, with smokers having more respiratory symptoms and signs, and reduced FEV1 compared with non smokers. The five most common respiratory conditions diagnosed were bronchial asthma, chronic bronchitis, pulmonary tuberculosis, upper respiratory tract infections and allergic rhinitis. On follow-up, there were also two cases of asbestosis and one case of bronchial carcinoma. The asbestosis cases were probably related to heavy occupational exposure to asbestos fibres in the past, before governmental regulations were gazetted in 1986. Further follow-up is essential for continued monitoring of the health status of asbestos workers.
Gaucher Disease may now be treated with enzyme replacement therapy (ERT) or bone marrow transplantation (BMT). Both have their advantages and disadvantages. Results with BMT are curative when successful but limited by the scarcity of an appropriate donor. ERT offers very good relief of symptoms but treatment is lifelong and cost of treatment exorbitant. Patients in developing countries are particularly disadvantaged and management remains a dilemma for both doctor and patient.
We describe two cases of transfusion dependent thalassaemics with chronic hepatitis C virus infection whom were treated successfully with interferon and ribavirin, following failure of response or relapse after an initial response to interferon monotherapy. They had sustained virological response for more than twelve months after completing therapy. Transfusion requirements were significantly increased during the combination therapy, probably due to ribavirin-induced haemolysis. Serum ferritin level decreased significantly during the treatment. Combination therapy with interferon alfa and ribavirin may be a feasible treatment option for some nonresponders to prior interferon monotherapy.
A 27-year old woman presented with fever, weight loss, arthralgia, macular skin rash and bilateral axillary lymphadenopathy. The histology of an excised lymph node showed evidence suggestive of Kikuchi disease. Subsequent laboratory tests showed evidence of Systemic Lupus Erythematosus, underscoring the importance of considering other diagnoses in a nodal histological diagnosis of Kikuchi disease, a benign condition of unknown aetiology.
A term newborn infant developed hypovolaemic shock shortly after birth. She was pale with gross hepatomegaly. She required multiple boluses of intravenous fluids, blood products as well as inotropic support. Blood investigations showed persistent thrombocytopenia, anaemia and disseminated intravascular coagulopathy (DIC). She also developed heart failure. She finally succumbed on the eleventh day of life. Autopsy revealed haemangiomatosis involving the liver, lungs, gastrointestinal tract, kidneys and adrenals.
Removal of the whole sternum for malignant tumours results in a large defect, causing severe deformity and possible paradoxical movements of the chest wall. The reconstruction of the resultant large defect of the chest wall is often complex and difficult. Commonly used materials include rib autograft, steel strus acrylic plate and various synthetic meshes such as Goretex or Marlex mesh, with a myocutaneous flap for coverage. A case of a 48-year-old man with sternal chondrosarcoma successfully treated with thoracoplasty using acrylic plate-marlex mesh combination following near total resection of sternum is reported.

This case has been reported because of its rarity and atypical clinical presentation. An 8-year-old boy presented with a gradually increasing swelling localised on the antero-medial aspect of the foot haemogram, erythrocyte sedimentation rate (ESR), Mantoux and X-ray chest were normal. An irregular lytic lesion of the talus was seen on the x-ray of the affected part. Ziehl Nelson staining of the aspirated fluid revealed acid-fast bacilli. Material obtained after curettage and bone grafting was sent for histopathological examination which confirmed the diagnosis of tuberculosis. Post operatively a below knee cast was given for 12 weeks and anti tubercular treatment was given for 20 months. At the end of the treatment patient had full and painless motion at the ankle and subtalar joint. The lytic lesion had healed on X-ray.
Otitis media with effusion (OME) is a very common condition seen in children, and is the commonest cause of hearing loss in an infant. It is also a fairly common condition encountered by the family practitioner, and often the family practitioner is the first doctor the parents bring the child to. Otitis media with effusion is a simple condition but, if left undiagnosed or untreated, can lead to preventable long-term consequences. Hence, a high index of suspicion is necessary, early and accurate diagnosis, prompt treatment, with close follow-up is of essence. The epidemiology, aetiological factors, clinical presentations, diagnosis, various medical and surgical options, cost-effectiveness of therapy and the impact of OME on the child's development are discussed.
