    In multiethnic countries such as Malaysia more than six different languages are spoken by patients in publicly-funded clinics. Sometimes doctors are unable to speak the patient's language and there are no professional interpreters. Research on doctor-patient communication has rarely included the language variable and its impact on information exchange and patient outcome in consultations where the doctor does not speak the patient's language. The few studies carried out in linguistically plural societies show that doctors and patients can face language barriers and trained interpreters are not always available. This paper illustrates some of the problems of using untrained interpreters in a primary care setting. Consultations were audiotaped and the transcripts were used to show how messages underwent distortion, condensation, and omission in interpreter-mediated consultations. Research needs to be carried out based on a model of doctor-patient communication which reflects the realities of the multilingual consultation.

    Parasitic infections have been reported to be relatively common among the Southeast Asian labourers in Taiwan. This study, conducted in 1992-6, was designed to determine the temporal changes of the prevalence. Faecal specimens were examined by the formalin-ethyl acetate sedimentation technique and blood samples screened using the quantitative buffy coat technique and confirmed by Giemsa stained blood smear. The overall prevalence of intestinal parasitic infections was 10.3%. The annual prevalence decreased from 33.3% in 1992-3 to 4.6% in 1995-6. The Thai (12.0%) and Indonesian (11.1%) had a higher prevalence than the Malaysian (6.7%) and Filipinos (5.9%). Opisthorchis viverrini was the most important parasite in the Thai and Trichuris trichiura in the remaining groups. Moreover, no blood parasites were found in the labourers. The dramatic temporal decline in the intestinal parasitic infections suggests that limiting the entry of infected persons, periodic follow-ups, and immediate treatment of sporadic cases are necessary in preventing transmission of non-indigenous parasites through large population change.

    BACKGROUND: Hip fracture as a consequence of osteoporosis is an important cause of morbidity and mortality among the elderly. Due to improving life expectancy, the number of elderly individuals is increasing more rapidly in the developing countries of Asia, the Middle East, Africa, and South America. Incidence of hip fracture, which rises exponentially with age, varies substantially between countries and according to the age, sex, and ethnic distribution of the population. Highest rates are observed in Scandinavia and in whites in the US, intermediate in western Europe, and the lowest rates in Asia. Little is known about the epidemiology of hip fractures in the Middle Eastern populations. In particular, there are no published reports from any of the Arab countries. We have therefore estimated the incidence of hip fracture in Kuwait and compared it with other populations.

    METHODS: The study was conducted at a specialized orthopaedic hospital which provides services to residents in the three governorates--representing about 70% of the total population of Kuwait. All new hip fracture patients who were operated on or treated conservatively during the 4-year period (1992-1995) were included in the study. Hip fracture was defined as clinical and radiological evidence of fracture of the proximal femur. For comparison with other populations, age-specific incidence rates in females and males aged > or =50 years were standardized to the 1985 US population.

    RESULTS: A total of 513 cases of hip fracture (205 females, 308 males) were recorded during the study period: 293 (57.1%) cases occurred among Kuwaiti nationals and 220 (42.9%) among non-Kuwaitis (expatriates). Age-standardized rates (per 100,000) of hip fractures were, in Kuwaitis, 295 for females (95% CI: 238.8-350.8) and 200 for males (95% CI: 163.3-236.5)--much higher than those observed in other Asian countries such as Korea, Singapore, China, Malaysia, and Japan (41-202 for females, 49-100 for males). Rates in Kuwaiti females were similar to those observed in some of the European countries (Italy, UK, France) and in Asian females in the US. In contrast, rates in Kuwaiti males, which were relatively high, were almost equal to those observed in white males in the US. Rates of hip fracture in non-Kuwaitis (374 for females [95% CI: 247.6-500.8], 215 for males [95% CI: 126.5-302.9]), who predominantly (96%) originate from southeast Asian and Arab countries, were similar to those observed in Kuwaiti nationals.

    CONCLUSIONS: The incidence of hip fracture in the Kuwaiti population is higher than that reported from other countries in Asia and is comparable to the incidence in some of the western European and North American populations.

    In September 1997, plants of Hibiscus manihot (locally called nambele) were observed on Vaitupu Island, Tuvalu, exhibiting an angular leaf mosaic and chlorosis that was not always clearly discernible. Electron microscopy of negatively stained sap from affected leaves revealed the presence of numerous isometric virus particles 28 nm in diameter. Poly-acrylamide gel electrophoresis of purified virus gave a single protein band of Mr 38,000 similar to that of the carmoviruses. Immunosorbent electron microscopy tests with antisera kindly provided by N. Spence showed the virus to be hibiscus chlorotic ringspot carmovirus (HCRSV) (1). This virus is also reported from El Salvador, the U.S., Australia, Thailand, Malaysia, Fiji, the Solomon Islands, and Vanuatu. It is not known how the virus reached Tuvalu but we suspect it was via infected cuttings, which were imported for the production of food supplements to combat acute deficiencies of vitamins A and C in the population. The virus is most likely to have been disseminated throughout the islands and atolls of Tuvalu through infected cuttings. Local spread within fields could occur through contaminated hands and cutting implements because of the ease with which the virus is mechanically transmitted. Reference: (1) H. E.Waterworth et al.

    White leaf streak, caused by Mycovellosiella oryzae (Deighton and Shaw) Deighton (syn. Ramularia oryzae), was found in Louisiana rice. The symptoms closely resemble those of narrow brown leaf spot caused by Cercospora janseana (Racib.) O. Const. (syn. C. oryzae (Miyake)), and it is difficult to distinguish between these two diseases. Initially both produce similar elongated light brown lesions, but later the lesions of white leaf streak become wider with a whitish center and are surrounded by a narrow light brown margin (2,3). The disease was first observed at the Rice Research Station, Crowley, LA, in 1996 on older leaves of the cultivar Lemont at maturity. Leaves containing the unusual lesion types were placed in a moist chamber and incubated at 28°C for 5 days. Abundant conidia were produced and the fungus was isolated on acidified potato dextrose agar (APDA) by single spore isolation and by plating infected tissues after surface sterilization in 40% Clorox for 10 to 15 min. The colonies grew slowly on APDA and were dark gray in color. The conidia formed in branched chains or singly. They were hyaline, cylindrical with tapering ends and a thick hilum; 0 to 3 septate, and 15 to 35 m long (1,3). Pathogenicity tests were conducted in the greenhouse on the Lemont and Cypress rice cultivars by spraying a conidial suspension (103-4 conidia per ml) onto leaf blades at boot stage. Conidia were produced by growing the fungus on PDA for 10 to 14 days. Inoculated plants were placed inside a humid chamber in a greenhouse and maintained for 4 to 5 weeks. Many elongated lesions similar to those observed in the field were produced 3 to 4 weeks after inoculation. Reisolation from these lesions yielded M. oryzae. With the same methods, 45 cultivars and lines were inoculated to determine their reactions to this disease. Most of the cultivars grown in the southern United States were moderately susceptible or susceptible to white leaf streak. Foreign cultivars tested, including BR-7, BR-11, Cica-4, Cica-6, Cica-7. Cica-8, Cica-9, Oryzica llanos, Rax clear, Teqing, and Tetep, were resistant. In 1997, the disease was found prevalent on many cultivars grown at the Rice Research Station, Crowley, LA. As symptoms of both white leaf streak and narrow brown leaf spot were sometimes observed on the same leaf; it is possible that the disease has been present, but not identified as a separate disease because of the similarity of the symptoms of the two diseases. A thorough survey is necessary to determine the extent of its occurrence and further studies are necessary to determine its yield loss potential. At present it appears to be a minor problem for Louisiana rice. White leaf streak has previously been recorded from Papua New Guinea on cultivated Oryza sativa, and from the Solomon Islands, Sabah, Nizeria, and Sierra Leone on cultivated O. glabberima Steudel and on wild perennial rice O. berthii A. Chev. (2). This is the first report of white leaf streak on cultivated rice in the United States. References: (1) F. C. Deighton. Mycol. Pap., CMI 144:1,1979. (2) F. C. Deighton and D. Shaw. Trans.

    Hevea brasiliensis anther calli were genetically transformed using Agrobacterium GV2260 (p35SGUSINT) that harboured the β-glucuronidase (gus) and neomycin phosphotransferase (nptII) genes. β-Glucuronidase protein (GUS) was expressed in the leaves of kanamycin-resistant plants that were regnerated, and the presence of the gene was confirmed by Southern analysis. GUS was also observed to be expressed in the latex and more importantly in the serum fraction. Transverse sections of the leaf petiole from a transformed plant revealed GUS expression to be especially enhanced in the phloem and laticifers. GUS expression was subsequently detected in every one of 194 plants representing three successive vegetative cycles propagated from the original transformant. Transgenic Hevea could thus facilitate the continual production of foreign proteins expressed in the latex.

    A prospective cross-sectional study involving 14 government hospitals was undertaken for a period of 6 months in Malaysia to study the patterns of hysterectomy for gynaecological indications. A total of 707 patients were enrolled in the study consisting of 612 abdominal hysterectomies and 95 vaginal hysterectomies. Fibroids (47.6%) and uterovaginal prolapse (13.4%) formed the main indications for surgery. The initial preoperative diagnosis was accurate in 82.8% of cases. A different pathology from that initially suspected was noted in 118 cases. The overall complication rate was 7.9% but vaginal hysterectomies carried a statistically higher complication rate compared to abdominal hysterectomies. Urinary tract infection was significant in vaginal hysterectomies. Blood transfusion was required in 25.0% of abdominal and 6.3% of vaginal hysterectomies. There were no laparoscopic hysterectomies or mortality in this series.

    Monoclonal immunoglobulin deposition disease (MIDD) is characterized by the deposition of amorphous non-congophilic materials predominantly in the kidneys leading to nephrotic syndrome or renal failure. As with light chain amyloidosis. MIDD is associated with a paraproteinemia. We report a patient suffering from multiple myeloma with IgG kappa paraproteinemia and immunoglobulin deposits predominantly in the bone marrow. The deposits are both as amorphous non-congophilic materials, and in the form of crystals, an observation not reported before.

    In the field of human energy expenditure, the measurement of basal metabolic rate (BMR) is an essential element to derive energy requirement estimates for any given population. Besides basic anthropometrics data, this paper reports the generation of predictive equation for basal metabolic rates of healthy Malaysian adult from prospective measurements on 307 male and 349 females aged 18-60 years, using the Douglas bag technique. These new equations based on body-weight reveal that the current FAO/WHO/UNU (1985) predictive equations overestimate BMR of adult Malaysian by an average of 13% in males and 9% in female subjects while differences of between 4-5% were observed when compared to Henry & Rees (1991) equations for tropical people. There is a good reason to believe that the capacity to slow down metabolism amidst the hot and humid climate experience throughout the year as a genuine phenomenon for Malaysians. Similarly, these findings suggest that at equal energy intake recommendation for similar body weight, the lower energy needs of Malaysian could put them at greater risk for developing obesity. These observed deviations must be taken into account in formulating energy requirements of the population.

    The theoretical impact of the use of coconut cream (santan) powder and palm oil santan powder on the dietary levels of C12-16 saturated fatty acids (SFAs) and linoleic acid (18:2), and on serum total cholesterol (TC), was evaluated holding non-santan dietary variables constant. The prediction was based on a 2,300-kcal hypothetical diet, containing one santan-based dish or snack in each of the 5 daily meals with fat contributing 30% of total calories, while the santan contributed a total of 14% kcal (36g). Replacing coconut santan with palm oil santan reduced the overall dietary C12-16 SFAs from 10.8% kcal to 4.8% kcal (i.e. –6.0% kcal) and the virtual removal of lauric (12:0) + myristic (14:0) acids, while palmitic acid (16:0) rose by 3.3% kcal, and the polyunsaturated linoleic acid (18:2) increased by 1.13% kcal. Applying the Hegsted equation to these dietary fatty acid (FA) changes, predicted a serum TC reduction of 24 -31 mg/dL (0.62- 0.80 mM/L), with the hypocholesterolemic effect being influenced by the low-density lipoprotein receptor (LDLr) “set-point” of the individual(s) concerned. Thus, the prediction indicated that replacing coconut santan with palm oil santan in santan-based Malaysian dishes or snacks would have a significant beneficial impact on serum TC and hence, cardiovascular risk.

    Accidental stab wounds caused by door handles are rare. A case is presented where a boy sustained a stab injury by a door handle with resultant impaction of the door handle into his forearm. The injury was possibly predisposed by the design of the door lock-and-handle complex and precipitated by his activity, both of which could have been avoided by a different design of the door lock and handle complex and perhaps closer supervision while at school.

    Candidacidal assay was used to assess the phagocytic and killing activities of polymorphonuclear leukocytes from paediatric patients diagnosed to manifest with characteristics of atopic dermatitis. From this group of patients evaluated, all the 11 cases exhibited lower candidacidal activity in comparison to the normal children. However, there were no abnormalities observed in the engulfing abilities and myeloperoxidase activities of these leukocytes. The result indicated that lower killing capacity of polymorphonuclear leukocytes in these patients may contribute to the frequent bacterial infections in atopic dermatitis children.

    Congenital Coagulation Disorders (CCD) are inherited and present from birth. Their diagnosis depends on clinical awareness and correct laboratory investigations. The central registry for CCD or Congenital Bleeding Disorders (CBD) is at the Blood Services Centre, Kuala Lumpur Hospital and was established in 1975. There are 871 CCD registered. The commonest CCD are 631 (72%) Haemophilia A, 102 (12%) Haemophilia B and 93 (10.7%) von Willebrand's Disease. The other deficiencies registered are rare, only 45 in total:— Factor 1 (4), FV (4), FVII (21), FX (4), FXII (6), and FXIII (6). Diagnosis is based on clinical suspicion, screening tests namely the Prothrombin Time (PT) and activated Partial Thromboplastin Time (aPTT) and confirmation of the diagnosis was by doing specific factor assays. Molecular studies were done on FVIII and FXIII. Treatment is by transfusing the deficient factor when there is bleeding and comprehensive care involving the specialities like the neurologist/ neurosurgeon /orthopaedic / physiotherapy/ dental besides the haematologist and paediatrician to manage the complicatioons seen. There are fewer problems now as patients are diagnosed earlier and managed better. There is now a good prognosis and a better quality of life.

    Twenty three major government hospitals were involved in a study to detect cases of child abuse and neglect admitted to the hospitals in 1995. There were 680 cases admitted for the year consisting of 328 cases of physical and 263 sexual abuse and 89 cases of neglect or abandonment. In the majority of hospitals, there was a predominance of physical abuse cases being admitted whereas in a few hospitals there were more cases of sexual abuse. 48.2% of those physically abused were below 5 years of age and 21.7% were 10 years and above. However, amongst those sexually abused, 14.4% were below 5 years and 46.7% were 10 years old and above. Fourteen of the children died due to physical abuse. In 11 cases, the death was due to subdural haemorrhage.

    To study the role of pulse oximetry in the assessment of acute asthma in children presenting to the A&E department, 360 children who presented themselves to the A&E department were enrolled into the study. Those admitted were found to have a lower mean Sa02 of 92% compared to those discharged with Sa02 of 94% (p < 0.001). After the initial treatment at the A&E, those admitted still have a lower mean Sa02 of 94% compared to those discharged with a mean Sa02 of 96% (p < 0.001). However taking Sa02 of 92% as a predictor of admission hada sensitivity of 39% and a specificity of 80% but it had a high negative predictive value of 92%. Hence pulse oximetry alone is not sensitive for predicting admission in acute asthma in children.

    Severe jaundice (serum bilirubin level > 340 gmol/L) occurred in 81 infants admitted to the Neonatal Intensive Care Unit (NICU) of the Maternity Hospital Kuala Lumpur (MHKL) in 1993. Of these 46 (56.8%) underwent 53 exchange transfusions. In-patient case notes were available for study on 41 of them. Two infants had no cause identified while 12 were associated with prematurity, 13 ABO incompatibility, 8 G6PD deficiency, 6 sepsis 2 Rh isoimmunisation and 6 miscellaneous causes. In 14 infants it was felt that exchange transfusions might have been avoided if they were detected earlier and phototherapy instituted promptly. Twenty six (26) infants were deemed to have been given phototherapy at the appropriate time but jaundice increased to exchange transfusion levels, threshold values depending on the unit in charge. Use of higher intensity phototherapy might have been more effective in some of the cases. Available data showed similar outcomes in both groups.

    From November 1996 to December 1997, 24 infants with neonatal cholestasis were referred to the Department of Paediatrics, University of Malaya Medical Center, Kuala Lumpur for further investigations. Nineteen had neonatal hepatitis. There was considerable delay in referral of infants with cholestasis; the mean age of referral was 63.7 days. None had a positive family history of neonatal hepatitis. All infant had hepatomegaly and ten had splenomegaly. The stools were slightly pale in thirteen, persistently acholic in three and normally pigmented in three infants. Liver synthetic functions were normal in most of the infants. Cytomegalovirus (CMV) IgM antibodies were positive in seven but none were positive for toxoplasma or rubella. al - antitrypsin deficiency, hypothyroidism, and galactosaemia were excluded in all infants. DISIDA scans were performed in seventeen infants, being non-excretory in eight. Liver biopsies were performed in fifteen infants, showing neonatal hepatitis in fourteen, while histological features of large duct obstruction was seen in one. In majority of infants (eight out of ten) the jaundice disappeared by six months. Two infants had progressive jaundice and liver function impairment.

    This research describes a comparative study using convenience sampling on management of intravenous lines in Maternity Neonatal Intensive Care Unit (MNICU), HKL. Questionnaires were answered by nurses and the techniques of anchoring, splinting and maintaining of intravenous lines by nurses in MNICU were observed by the researchers. The study showed that nurses with less than two years experience working in MNICU had significantly less knowledge and skills in the management of intravenous lines and are likely to encounter more difficulties and complications, compared to nurses with more experience.

    Background - Cardiac mumurs are common in childhood and are often innocent in nature. With careful examination, most innocent murmurs can be reliably diagnosed by a paediatric cardiologist, thus obviating the need for further investigations.

    Aim - To look at the prevalence of cardiac murmurs amongst standard one schoolchildren in an urban setting, and calculate the sensitivity, specificity, positive and negative predictive values of clinical diagnosis in differentiating innocent from pathological murmurs.

    Methods - One thousand three hundred and fourteen students from 7 primary schools in the district of Gombak were examined during a routine school health examination. Those who were found to have murmurs were referred for echocardiography. A diagnosis was made at the time of clinical examination and following echocardiography. Children with median sternotomy, lateral or posterior thoracotomy scars or those with previously diagnosed cardiac lesions were excludedfrom the study.

    Results - Thirty six children were referred for echocardiography out of which 2 were confirmed to have underlying cardiac disease on echocardiography. The prevalence of previously undiagnosed cardiac mumurs in this study was 3%. The sensitivity of clinical examination in diagnosing pathological murmurs was 100% while the specificity was 75%. Positive predictive value was 25% and negative predictive value was 100%. Forty three percent of the students who underwent echocardiography were found to have trivial pulmonary regurgitatibn on Doppler echocardiography.

    Conclusion - The prevalence of previously undiagnosed cardiac murmurs is low in this study. This may be due to the fact that they are detected and treated at an earlier age. There is need to conduct a similar study in a rural setting to compare the results.

    The total and allergen-specific IgE response of patients with rhinitis, rhinoconjunctivities, rhinitis with asthma and rhinitis with dermatitis was analyzed to a panel of twelve high risk airborne and food allergens. It has been found that this panel will detect 96 percent of the allergen-causing diseases in children. It was found that 26 (76%) of the 34 young patients had a family history for atopy suggesting a high frequency of inheritance of allergic disorders. Elevated total IgE was found in most patients with allergic disease. Positive IgE antibody response to two species of Dermatophagoides mite-allergens was found in 7/12 (58%) patients with rhinitis, 11/11 (100%) patients with rhinoconjunctivitis, 7/9 (78%) cases ofrhinitis with asthma and 3/3 (100%) cases of rhinitis with dermatitis. Some of the patients also responded to food allergens. Food allergy was noted in 4/12 (33%) cases of rhinitis, 11/11 (100%) cases of rhinoconjunctivitis, 4/9 (44%) cases of rhinitis with asthma and 1/3 (33%) cases of rhinitis with dermatitis. Patients with rhinoconjunctivitis who tested positive at high titres for mites invariably had enhanced response for cockroaches, shrimps and crabs suggesting invertebrate antigen cross-reactivity. A few patients however, did not show this type of cross-reactivity although they had high titres of anti-mite IgE antibodies indicating that they responded to non cross-reacting allergen epitopes. Response to multiple allergens appears to be a common feature of most patients with respiratory or skin allergic diseases. The prevalence of multiple target-organ allergy to wide variety offood and environmental allergens complicates the long term management ofpatients with such allergic disorders.
