Fulltext Risk factors for wheeze in the last 12 months in preschool children

Quah BS, Mazidah AR, Simpson H

Asian Pac J Allergy Immunol, 2000 Jun;18(2):73-9.
PMID: 10928618

Most children with asthma develop their symptoms before the age of 5 years and many preschool wheezers continue to wheeze in the early school years. It is thus important to investigate the factors that predispose young children to wheeze. The objective of this study was to investigate the relevant environmental and family influences on recent wheeze (wheeze within the last 12 months) in preschool children. A cross-sectional study was conducted in five primary health clinics in the district of Kota Bharu from April to October 1998. Nurses from these clinics distributed Bahasa Malaysia questionnaires containing questions on asthma symptoms, environmental risk factors, family's social status and family history of atopy and wheeze to preschool children aged 1-5 years during their home visits. The respondents were parent(s) or carer(s) of the children. A total of 2,524 (87.7%) complete questionnaires were available for analysis of risk factors. One hundred and fifty six (6.2%) children had current wheeze. Significant risk factors associated with current wheeze were a family history of asthma (O.R. = 6.36, 95% C.I. = 4.45-9.09), neonatal hospital admission (O.R. = 2.38, 95% C.I. = 1.51 - 3.75), and a maternal (O.R. = 2.12, 95% C.I. = 1.31-3.41) or paternal (O.R. = 1.52, 95% C.I. = 0.95-2.43) history of allergic rhinitis. Among environmental factors examined, namely, household pets, carpeting in bedroom, use of fumigation mats, mosquito coils and aerosol insect repellents, maternal and paternal smoking, and air conditioning, none were associated with an increased risk of wheeze. In conclusion, the strongest association with current wheeze was a family history of asthma. Also significant were neonatal hospital admission and a history of allergic rhinitis in either the mother or father. None of the environmental factors studied were related to current wheeze in preschool children.

Spontaneous intracerebral hemorrhage in northeast Malaysian patients: a four-year study

Muiz AJ, Abdullah J, Naing NN, Ghazaime G, Ariff AR

Neuroepidemiology, 2003 May-Jun;22(3):184-95.
PMID: 12711851

The aim of this study was to compare nonsurgical versus stereotactic aspiration of intracerebral hematomas in relation to clinical aspects, computed tomographic imaging features of the brain, laboratory parameters and specific risk factors that may influence the outcome in southeast Asian Malay patients. Fifty-five of the patients with intracerebral hemorrhage (ICH) underwent stereotactic aspiration and 57 did not. Analysis was done on risk factors, locations and treatments of ICH, and the final outcomes measured by the Glasgow Outcome Scale. A total of 112 patients were evaluated. Mean age was 52 years with ages ranging from 12 to 80 years. Hypertension was seen in 60.7% of patients with ICH. The mortality rate was 25% by 3 months. 58.9% had a poor final outcome, while 41.1% had a good outcome. The selected variables were incorporated into models generated by multiple logistic regression method analysis to define the significant predictors of outcome. Significant predictors of outcome were the Glasgow Coma Scale score on admission, the duration of surgery and the total volume of the hematoma. Significant predictors of mortality were high total white blood cell differential count, low plasma protein, and high plasma lactate dehydrogenase and brain edema. The study suggests that stereotactic aspiration of patients with ICH does not offer any definite advantage over conservative treatment.

Vitamin E in cardiovascular disease: has the die been cast?

Yusoff K

Asia Pac J Clin Nutr, 2002;11 Suppl 7:S443-7.
PMID: 12492632

Cardiovascular disease, in particular coronary artery disease (CAD), remains the most important cause of morbidity and mortality in developed countries and, in the near future, more so in the developing world. Atherosclerotic plaque formation is the underlying basis for CAD. Growth of the plaque leads to coronary stenosis, causing a progressive decrease in blood flow that results in angina pectoris. Acute myocardial infarction and unstable angina were recently recognised as related to plaque rupture, not progressive coronary stenosis. Acute thrombus formation causes an abrupt coronary occlusion. The characteristics of the fibrin cap, contents of the plaque, rheological factors and active inflammation within the plaque contribute to plaque rupture. Oxidative processes are important in plaque formation. Oxidized low density lipoproteins (LDL) but not unoxidized LDL is engulfed by resident intimal macrophages, transforming them into foam cells which develop into fatty streaks, the precursors of the atherosclerotic plaque. Inflammation is important both in plaque formation and rupture. Animal studies have shown that antioxidants reduce plaque formation and lead to plaque stabilisation. In humans, high intakes of antioxidants are associated with lower incidence of CAD, despite high serum cholesterol levels. This observation suggests a role for inflammation in CAD and that reducing inflammation using antioxidants may ameliorate these processes. Men and women with high intakes of vitamin E were found to have less CAD. Vitamin E supplementation was associated with a significant reduction in myocardial infarction and cardiovascular events in the incidence of recurrent myocardial infarction. In the hierarchy of evidence in evidence-based medicine, data from large placebo-controlled clinical trials is considered necessary. Results from various mega-trials have not shown benefits (nor adverse effects) conferred by vitamin E supplementation, suggesting that vitamin E has no role in the treatment of CAD. These results do not seem to confirm, at the clinical level, the effect of antioxidants against active inflammation during plaque rupture. However, a closer examination of these studies showed a number of limitations, rendering them inconclusive in addressing the role of vitamin E in CAD prevention and treatment. Further studies that specifically address the issue of vitamin E in the pathogenesis of atherosclerosis and in the treatment of CAD need be performed. These studies should use the more potent antioxidant property of alpha-tocotrienol vitamin E.

Predictors of failure of nasal continuous positive airway pressure in treatment of preterm infants with respiratory distress syndrome

Boo NY, Zuraidah AL, Lim NL, Zulfiqar MA

J Trop Pediatr, 2000 Jun;46(3):172-5.
PMID: 10893920

A case-control study was carried out on 97 consecutive preterm (< 37 weeks) infants to determine predictors associated with failure of nasal continuous positive airway pressure (CPAP) in the treatment of respiratory distress syndrome (RDS). Logistic regression analysis showed that only three risk factors were significantly associated with failed CPAP. These were: moderate or severe RDS (odds ratio: 5.9; 95 per cent confidence interval (CI): 2.2-16.0); septicemia during CPAP therapy (OR: 8.8; 95 per cent: CI 1.5-50.7); and pneumothorax during CPAP therapy (odds ratio: 6.9; 95 per cent: CI 1.1-41.7).

Why is acute leukemia more common in males? A possible sex-determined risk linked to the ABO blood group genes

Jackson N, Menon BS, Zarina W, Zawawi N, Naing NN

Ann Hematol, 1999 May;78(5):233-6.
PMID: 10391104

Acute leukemia is more common in males at almost every age, and this fact remains unexplained. A study was carried out in northeast peninsular Malaysia, where the population is predominantly Malay, to examine whether there was a difference in ABO blood group distribution between males and females with acute leukemia (AL). The ABO blood groups of 109 male and 79 female patients with AL (98 ALL, 90 AML) were compared with those of 1019 controls. In the control population, 39.7% were group O. Among males with AL, 39.4% were group O, whereas among females with AL, the proportion was 24.1% (p=0.03). The same trend to a lower proportion of group O among females was seen if the group was divided into adult/pediatric or lymphoblastic/myeloblastic groups, though these differences were not statistically significant. If these findings can be confirmed, they suggest the presence of a "sex-responsive" gene near to the ABO gene locus on chromosome 9, which relatively protects group O women against AL, at least in our population. The existence of such a gene might also partly explain why acute leukemia, and possibly other childhood cancers, are more common in males.

Prevalence of peripheral artery disease in urban high-risk Malaysian patients

Amudha K, Chee KH, Tan KS, Tan CT, Lang CC

Int J Clin Pract, 2003 Jun;57(5):369-72.
PMID: 12846339

Atherosclerosis is a progressive, disseminated condition that affects all the vascular beds. Peripheral arterial disease (PAD), a manifestation of atherosclerosis, measured non-invasively in the legs by ankle-brachial index (ABI) is associated with increased cardiovascular morbidity and mortality. Though several studies in the western industrialised countries have shown that PAD is widely prevalent in the general older population at risk, not much data are available in the South East Asian developing countries. We have conducted an epidemiological survey on the prevalence of PAD in high-risk patients at an urban hospital in Malaysia. A total of 301 consecutive patients aged 32-90 years were recruited during their follow-up clinic visits for established cardiovascular disease, ischaemic stroke or diabetes mellitus > or = 5 years. All participants underwent ABI measurement and were subjected to the Edinburgh claudication questionnaire to assess leg symptoms. The prevalence of PAD in our high-risk population was 23%, of which only 27% were symptomatic with the classical intermittent claudication. All the patients with PAD were diagnosed at the time of the study. PAD was found in 33% of patients with pre-existent cardiovascular disease, 28% in patients with ischaemic stroke and 24% in diabetic patients. PAD was also highly prevalent among the younger patients. Our study has shown that PAD is highly prevalent among high-risk Malaysian patients and is not necessarily a disease of older age. Only 27% of these patients were symptomatic. All the subjects with PAD were diagnosed at the time of the study, which would suggest it is an unrecognised and underdiagnosed condition, even in patients with atherosclerotic risk factors.

A comparison of cardiovascular risk factors among Indo-Asian and caucasian patients admitted with acute myocardial infarction in Kuala Lumpur, Malaysia and Birmingham, England

Dhanjal TS, Lal M, Haynes R, Lip G

Int J Clin Pract, 2001 Dec;55(10):665-8.
PMID: 11777289

Indo-Asians in the UK are at an increased risk of coronary artery disease (CAD); this may be a reflection of their cardiovascular risk factor profile as well as of a more sedentary lifestyle. We hypothesised that Indo-Asians in Malaysia and the UK may exhibit a similar cardiovascular risk factor and physical activity profile, which would be more adverse compared with caucasians. We studied 70 consecutive Indo-Asian patients admitted to hospitals in Kuala Lumpur, Malaysia (n=42; 35 males; mean age 60.6 years, SD 11.8); and Birmingham, England (n=28; 20 males; mean age 60.8 years, SD 12.9). Both groups of Indo-Asian patients were compared with 20 caucasian patients (13 males; mean age 62.7 years, SD 9.4) admitted with myocardial infarction from Birmingham. There was a higher prevalence of diabetes among Indo-Asians in both countries than among caucasians (p=0.0225). By contrast, caucasians had a higher prevalence of hypercholesterolaemia (p=0.0113), peripheral vascular disease (p=0.0008), regular alcohol consumption (p<0.0001) and family history of CAD (p=0.0041). There were no significant differences in mean age, body mass index or blood pressures. There was a significantly lower leisure activity score (p=0.001) and total physical activity score (p=0.003) among Indo-Asians in both countries than among caucasians. This survey has demonstrated differences in cardiovascular risk factors among Indo-Asian and caucasian patients. The high prevalence of diabetes, as well as the lower physical activity and sedentary lifestyles among Indo-Asians, in both Malaysia and the UK, may in part contribute to the high incidence of CAD in this ethnic group.

Eating disorders in the Far East

Tsai G

Eat Weight Disord, 2000 Dec;5(4):183-97.
PMID: 11216126

OBJECTIVE: To investigate eating disorders (EDs) prevalence rates among Asian populations and identify characteristics that distinguish them from their Western counterparts.
METHOD: Potential references were identified through an English-language literature search using Medline, Psychinfo, Dissertation Abstracts (1966 to 1999) and through extensive manual searching of textbooks, reviews and reference lists.
RESULTS: The majority of studies related to EDs were conducted in Japan and China and a few were conducted in Singapore, Malaysia, Taiwan, and Korea whereas there was none in the Philippines, Laos, Vietnam, Cambodia, Myanmar, Indonesia and Thailand. Prevalence rates in Japan range from 0.025 to 0.030% for anorexia nervosa (AN) and from 1.9 to 2.9% for bulimia nervosa (BN). Community studies in China have found the AN prevalence to be 0.01% and BN rates ranging from 0.5% to 1.3%. These rates are lower than ED rates in the West (particularly the U.S. and Britain). Body dissatisfaction (BD) and dieting rates, however, were similar to those in the West. BD rates ranged from 68% (Taiwan) to 81% (Korea) and dieting rates ranged from 34% (Taiwan) to 68% (Japan). Sociocultural and developmental risk factors were relevant to this population.
CONCLUSIONS: EDs in Asian populations have received little attention because they have been predominantly viewed as associated with Western culture. Classified by many as a "culture-bound syndrome" of the West, they may really be a culture-change syndrome.

Design of the multicenter Australian study of epidural anesthesia and analgesia in major surgery: the MASTER trial

Rigg JR, Jamrozik K, Myles PS, Silbert B, Peyton P, Parsons RW, et al.

Control Clin Trials, 2000 Jun;21(3):244-56.
PMID: 10822122

The Multicenter Australian Study of Epidural Anesthesia and Analgesia in Major Surgery (The MASTER Trial) was designed to evaluate the possible benefit of epidural block in improving outcome in high-risk patients. The trial began in 1995 and is scheduled to reach the planned sample size of 900 during 2001. This paper describes the trial design and presents data comparing 455 patients randomized in 21 institutions in Australia, Hong Kong, and Malaysia, with 237 patients from the same hospitals who were eligible but not randomized. Nine categories of high-risk patients were defined as entry criteria for the trial. Protocols for ethical review, informed consent, randomization, clinical anesthesia and analgesia, and perioperative management were determined following extensive consultation with anesthesiologists throughout Australia. Clinical and research information was collected in participating hospitals by research staff who may not have been blind to allocation. Decisions about the presence or absence of endpoints were made primarily by a computer algorithm, supplemented by blinded clinical experts. Without unblinding the trial, comparison of eligibility criteria and incidence of endpoints between randomized and nonrandomized patients showed only small differences. We conclude that there is no strong evidence of important demographic or clinical differences between randomized and nonrandomized patients eligible for the MASTER Trial. Thus, the trial results are likely to be broadly generalizable.

Nissapatorn V, Lee CK, Cho SM, Rohela M, Anuar AK, Quek KF, et al.

Southeast Asian J. Trop. Med. Public Health, 2003;34 Suppl 2:80-5.
PMID: 19238664

Three hundred and one sera of HIV/AIDS patients were tested for anti-Toxoplasma IgG antibody by ELISA technique. The seroprevalence of toxoplasmosis was 41.2% (95% CI: 35.5-46.9) in HIV/AIDS patients. The seroprevalence was significantly higher in the Malay (57.9%) than the Chinese (38.7%), followed by the Indian patients (29.6%) (p<0.05). No possible risk factor, such as contact with cats, consumption of uncooked meat, and history of blood transfusions was found to have any significant association with the presence of anti-Toxoplasma antibody in the study sample (p>0.05). Multivariate analysis was employed to find any association between Toxoplasma seroprevalence and a single subject having single or multiple risk factors. It was found that the association was not statistically significant (p>0.05). Among the HIV/AIDS study samples, 124 (41.2%) samples were found to have positive anti-Toxoplasma antibody, the association between the presence of anti-Toxoplasma antibody and CD4 cell count was determined but no statistically significant association was found (p>0.05). During the study period, only one case of active CNS toxoplasmosis was registered and the diagnostic criteria included: clinical presentations, CT scan finding, serological evidence of anti-Toxoplasma IgG antibody, and respose to anti-Toxoplasma therapy.

Knowledge and perception of risk for HIV and condom use among male injecting drug users in Cebu City, Philippines

Amadora-Nolasco F, Alburo RE, Aguilar EJ, Trevathan WR

Drug Alcohol Rev, 2002 Jun;21(2):137-43.
PMID: 12188992

Injecting drug users (IDU) represent a small fraction of the HIV and AIDS cases in the Philippines. To determine if these people are engaging in behaviors that put them at risk for HIV, interviews were conducted with 360 male IDUs in Cebu City, Philippines, from 1997 to 1999, as part of a national surveillance system. The interviews assessed knowledge about HIV transmission, sources of information about HIV/AIDS, perceived risks of contracting HIV, needle-sharing practices, condom use, self-reported signs and symptoms of STDs and number of sex partners. Although most of the men were able to recognize behaviors accurately that put them at risk for HIV, more than two-thirds claimed that they shared needles and almost two-thirds of those who were sexually active claimed that they never used condoms. Intervention strategies must be developed for this population if the nation is to avoid the dramatic increase in HIV infection among IDUs that has been witnessed in neighboring Southeast Asian nations such as Malaysia and Vietnam.

Fulltext Risk factors for infection in total hip replacement surgery at Hospital Kuala Lumpur

Yong KS, Kareem BA, Ruslan GN, Harwant S

Med J Malaysia, 2001 Jun;56 Suppl C:57-60.
PMID: 11814251 MyJurnal

Sixty-seven primary THR surgeries in 57 patients between January 1992 and December 1998 were reviewed after a mean follow-up of 35.9 months. The rate of superficial and deep wound infections were 11.9% and 1.5% respectively. The most common organism in superficial wound infection was Staphylococcus aureus. The factors that were significantly associated with superficial wound infection were diabetes mellitus (p= 0.0230) obesity (p=0.0088). The patients who developed superficial wound infection have a significantly longer duration of surgery compared to patients without infection (p=0.014). However, there was no significant difference between the mean age among patients with and without superficial wound infection (p=0.814).

Risk factor screening for abnormal glucose tolerance in pregnancy

Shamsuddin K, Mahdy ZA, Siti Rafiaah I, Jamil MA, Rahimah MD

Int J Gynaecol Obstet, 2001 Oct;75(1):27-32.
PMID: 11597616 DOI: 10.1016/s0020-7292(01)00468-4

OBJECTIVES: To assess the prevalence and association of frequently used screening risk factors for gestational diabetes mellitus (GDM) and to compare the validity and cost of universal screening with risk factor screening.

METHOD: A cross-sectional survey of 768 pregnant women at > or = 24 weeks' gestation who were attending the antenatal clinic at the Hospital Universiti Kebangsaan Malaysia (HUKM) was made. Risk factors were determined using a questionnaire. An abnormal oral glucose tolerance test was defined as a 2-h post-prandial blood sugar level of > or = 7.8 mmol/l.

RESULTS: A total of 191 pregnant mothers (24.9%) had GDM. The most commonly identified screening factors were positive family history of diabetes mellitus (31.4%), history of spontaneous abortion (17.8%), vaginal discharge and pruritus vulvae in current pregnancy (16.0%), and maternal age greater than 35 years (14.7%). Five hundred and thirteen mothers (66.8%) had at least one risk factor. All screening risk factors, except past history of diabetes mellitus in previous pregnancy and maternal age, were not significantly associated with abnormal glucose tolerance (GT). Risk factor screening gave a sensitivity of 72.2% and a specificity of 35.0%. Universal screening would cost RM 12.06 while traditional risk factor screening would cost RM 11.15 per identified case and will have missed 53 of the 191 cases.

CONCLUSIONS: Risk factor screening scored poorly in predicting GDM. Cost analysis of universal compared with traditional risk factor screening showed a negligible difference. Thus universal screening appears to be the most reliable method of diagnosing GDM.

Hypertension and stroke in Asia: prevalence, control and strategies in developing countries for prevention

Singh RB, Suh IL, Singh VP, Chaithiraphan S, Laothavorn P, Sy RG, et al.

J Hum Hypertens, 2000 11 30;14(10-11):749-63.
PMID: 11095165

Reliable statistics related to the prevalence, incidence and mortality of hypertension and stroke are not available from Asia. The data may be in national or institutional reports or journals published in the local language only. The mortality rate for stroke has been on the decline since the mid 1960s in the developed countries of Asia, such as Australia, New Zealand, and Japan, with some improvement in Singapore, Taiwan and Hong Kong, some areas of China and Malaysia about 15 years later. In India, China, Philippines, Thailand, Sri Lanka, Iran, Pakistan, Nepal, there has been a rapid increase in stroke mortality and prevalence of hypertension. The prevalence of hypertension according to new criteria (>140/90 mm Hg) varies between 15-35% in urban adult populations of Asia. In rural populations, the prevalence is two to three times lower than in urban subjects. Hypertension and stroke occur at a relatively younger age in Asians and the risk of hypertension increases at lower levels of body mass index of 23-25 kg/m2. Overweight, sedentary behaviour, alcohol, higher social class, salt intake, diabetes mellitus and smoking are risk factors for hypertension in most of the countries of Asia. In Australia, New Zealand and Japan, lower social class is a risk factor for hypertension and stroke. Population-based long-term follow-up studies are urgently needed to demonstrate the association of risk factors with hypertension in Asia. However prevention programmes should be started based on cross-sectional surveys and case studies without waiting for the cohort studies.

Adjuvant chemotherapy in "high risk" patients after Wertheim hysterectomy--10-year survivals

Sivanesaratnam V

Ann Acad Med Singap, 1998 Sep;27(5):622-6.
PMID: 9919328

Although the primary operative mortality following radical hysterectomy for stage IB and early stage IIA cervical carcinoma is less than 1%, survival is poor in those patients with histological evidence of "risk" features--lymph node metastases, lymphatic vascular tumour permeation and clinically undetected parametrial metastases. In the 7-year period 1983 to 1989, 239 patients with stage IB and early IIA disease had radical hysterectomy and pelvic lymphadenectomy. One hundred and eight patients (45.2%) had various poor prognostic histological features and received adjuvant chemotherapy--70 had cisplatin, vinblastine, bleomycin (PVB), 16 had mitomycin C (MMC) and 22 others received mitomycin C + 5-fluorouracil (5-FU). Although not randomised, the risk factors present in each group were identical. These patients have now been followed up for periods ranging from 8 to 14 years. All recurrences, except one, occurred within 23 months of surgery; in the remaining this occurred 8 years later. This suggests that very close long-term follow-up is needed. Recurrences were markedly higher in the group who refused adjuvant chemotherapy (31.6%). The 10-year survival in patients without risk factors was 97.2%. In those patients with risk factors refusing adjuvant therapy it was 73.7%. The adjuvant chemotherapy group had a better survival of 86.1% (P = 0.001). The 10-year survivals in patients with positive nodes were similar--66.7% in the MMC group and 71.4% in the PVB group. The 10-year survival in patients with squamous cell carcinoma was significantly better (90.3%) in the mitomycin C (and MMC + 5-FU) group compared to the PVB group (80.1%) (P = 0.005). The 10-year survival in patients with adenocarcinoma and adenosquamous carcinoma was significantly better (96.3%) in the PVB group compared to those receiving MMC (and MMC + 5-FU) (57.1%) (P = 0.01). It would, thus, appear that the adjuvant chemotherapy of choice for patients with squamous cell carcinoma would be MMC (and MMC + 5-FU) and for those with adenocarcinoma, the PVB regime.

Cardiovascular risk factors in non-insulin-dependent diabetics compared to non-diabetic controls: a population-based survey among Asians in Singapore

Hughes K, Choo M, Kuperan P, Ong CN, Aw TC

Atherosclerosis, 1998 Jan;136(1):25-31.
PMID: 9544728

Cardiovascular risk factors were compared between 126 people with non-insulin-dependent diabetes mellitus (NIDDM) and 530 non-diabetics (controls), in a random sample of people (Chinese, Malays, and Asian Indians) aged 40-69 years from the general population of Singapore. Data were adjusted for age and ethnicity. For both genders, people with NIDDM had higher mean body mass indices, waist-hip ratios and abdominal diameters. They also had a higher prevalence of hypertension, higher mean levels of fasting serum triglyceride, slightly lower mean levels of serum high-density-lipoprotein cholesterol, and higher mean levels of plasma plasminogen activator inhibitor-1 and tissue plasminogen activator (antigen). These factors are components of syndrome X (metabolic syndrome) and increase the risk of atherosclerosis and thrombosis. In contrast, there were no important differences for cigarette smoking, serum total and low-density-lipoprotein cholesterol, serum apolipoproteins A1 and B, plasma factor VIIc and plasma prothrombin fragment 1 + 2. Females with NIDDM, but not males, had a higher mean serum fibrinogen level than non-diabetics, which could explain why NIDDM has a greater cardiovascular effect in females than males. Serum lipoprotein(a) concentrations were lower in people with NIDDM. Mean levels of serum ferritin, a pro-oxidant, were higher in people with NIDDM than controls, but there were no important differences for plasma vitamins A, C and E, and serum selenium, which are anti-oxidants.

Prevalence of otitis media with effusion amongst pre-school children in Malaysia

Saim A, Saim L, Saim S, Ruszymah BH, Sani A

Int J Pediatr Otorhinolaryngol, 1997 Jul 18;41(1):21-8.
PMID: 9279632 DOI: 10.1016/s0165-5876(97)00049-9

A cross-sectional screening test was done to determine the prevalence of otitis media with effusion amongst, preschool children in two district in Malaysia, namely Kuala Lumpur an urban district and Kuala Selangor a rural district. It involved 1097 preschool children aged between 5 and 6 years old. Presence of otitis media effusion (OME) is based on abnormal otoscopic finding, Type B tympanogram and absence of ipsilateral acoustical reflex. The overall prevalence rate of OME was 13.8%. The prevalence in Kuala Lumpur was 17.9%, while in Kuala Selangor it was 9.48%. Bottle feeding during infancy and high socioeconomic status of the parents was statistically associated with higher incidence of OME. Other factors such as race, premature delivery, passive smoking, allergy, asthma and family size, had no influence on the prevalence of otitis media with effusion.

The predictive value of extremes of birth weight, mother's height and ethnic origin on the likelihood of emergency caesarean section

Hin LY, Khairuddin Y, Ng KB

Asia Oceania J Obstet Gynaecol, 1994 Dec;20(4):389-94.
PMID: 7832671

We reviewed the deliveries in a teaching hospital in a multiracial community over the period of one year (1988), and investigated the relationship between maternal height, ethnic origin, and the extremes of birth weight with the likelihood of emergency lower segment caesarean section (LSCS). After excluding patients with obvious indications for LSCS, 5,050 patients were entered in the study. Chi-square analysis showed that the risk of emergency LSCS is significantly higher in the Indians compared to Chinese and Malays, but does not differ significantly between the latter two groups. Logistic regression analysis showed that birth weight of less than 2,500 g or greater than 3,500 g is the most significant association with emergency LSCS rate. Conditional logistic regression showed that, provided the individuals conformed to the characteristics of the cohort in this study, risk of emergency LSCS for a 150 cm (25th centile) tall Indian pregnant lady is almost twice that of a 158 cm (75th centile) tall non-Indian).
