Fulltext Nosocomial bacterial sepsis in babies weighing 1000-1499 g in Kelantan

Halder D, Haque ME, Zabidi MH, Kamaruzzaman A

Med J Malaysia, 1999 Mar;54(1):52-7.
PMID: 10972005

From January to December 1992, 92 babies weighing 1000-1499 gm here to referred as very low birth weight (VLBW) were admitted to NICU (Neonatal Intensive Care Unit), Hospital University Sains Malaysia (HUSM). Sixty babies were inborn giving a VLBW rate of 7.5 per 1000 live births. Incidence of nosocomial sepsis was 32.6% (30/92) of whom 43.3% (13/30) died. Eighty percent (24/30) of the septic babies had blood culture positive for gram negative organisms of which 40% (12/30) were sensitive only to imipenem. Ventilator support within 24 hours of life was required in 41.3% (38/94) babies of whom 42% (16/38) babies developed nosocomial sepsis. Delayed initiation of feeding was significantly associated with nosocomial sepsis. A strict asepsis policy and early feeding of the VLBW infant are essential components of any strategy to prevent of sepsis due to nosocomial infection.

Avian mycoplasmosis in Asia

Sato S

Rev. - Off. Int. Epizoot., 1996 Dec;15(4):1555-67.
PMID: 9190025

Since 1954, avian mycoplasmosis has been considered a significant problem in chicken flocks in Japan and in other Asian countries. In Japan, Mycoplasma gallisepticum (MG) and M. synoviae (MS) infections were confirmed aetiologically in chicken flocks affected with respiratory disease or synovitis in 1962 and 1973, respectively. In other Asian countries, including Indonesia, the People's Republic of China, Korea, Malaysia, the Philippines, Taipei China and Thailand, the occurrence of mycoplasmosis in chicken flocks has been recognised serologically or aetiologically. Adverse atmospheric and environmental conditions, in addition to mixed infections of bacterial or viral origin, play an important role in the spread of MG and MS within chicken flocks or in the induction of clinical respiratory mycoplasmosis. Serological tests are important in determining and monitoring the mycoplasmal infection status of chicken flocks. The establishment of mycoplasma-free breeding stocks is recognised as essential for the control of avian mycoplasmosis. To eliminate the transmission of MG to the egg, treatment of infected breeder flocks or their progeny with anti-mycoplasmal antibiotics was effective in considerably reducing the infection rate but not in entirely eliminating MG infection. The preincubation heat treatment of chicken hatching eggs has proved an effective procedure for establishing MG- and MS-free breeding stocks in Japan. Vaccination against MG infection has been practised successfully in Japan and other countries.

Early post-traumatic seizures in children: clinical and radiological aspects of injury

Ong LC, Dhillon MK, Selladurai BM, Maimunah A, Lye MS

J Paediatr Child Health, 1996 Apr;32(2):173-6.
PMID: 9156530

OBJECTIVE: To determine the type and outcome of early post-traumatic seizures in children and the factors associated with it.
METHODOLOGY: A prospective observational study on all consecutive children with head injuries at the General Hospital Kuala Lumpur between November 1993 and December 1994. The onset, type and frequency of seizures occurring within the first week of injury were documented. Using inpatients as a cohort, logistic regression analysis was used to determine clinical and radiological variables significantly associated with seizures. The outcome 6 months post-injury was assessed using the Glasgow Outcome Scale.
RESULTS: Fifty-three of 966 children (5.5%) developed seizures within the first week of trauma. Seven (13.2%) occurred within 1 h of injury, 30 (56.6%) between 1 and 24 h and 16 (30.2%) after 24 h. Factors significantly associated with early post-traumatic seizures were female sex, age less than 2 years, loss of consciousness for more than 24h and acute subdural haematoma (P<0.01). Children with seizures had a poorer outcome (death or severe disability) than inpatients without seizures (21/53 vs 19/182, P<0.001). The outcome was worst in children with recurrent partial seizures, who had a longer injury-seizure interval and were more likely to have focal neurologic deficits compared to those with sporadic or generalized seizures.
CONCLUSIONS: Anticonvulsant prophylaxis to minimize the adverse effects of early seizures in head injury should be considered for young children (less than 2 years old) with subdural haematoma and a prolonged duration of coma. Prompt and effective control of recurrent seizures is recommended.

Cancer incidence in Asian migrants to New South Wales, Australia

Grulich AE, McCredie M, Coates M

Br. J. Cancer, 1995 Feb;71(2):400-8.
PMID: 7841061

Cancer incidence during 1972-90 in Asian migrants to New South Wales, Australia, is described. Overall cancer incidence was lower than in the Australia born in most migrant groups, and this reached significance in migrants born in China/Taiwan, the Philippines, Vietnam and India/Sri Lanka, and in male migrants born in Indonesia. For the majority of cancers, rates were more similar to those in the Australia born than to those in the countries of birth. For cancers of the breast, colorectum and prostate, rates were relatively low in the countries of birth, but migrants generally exhibited rates nearer those of the Australia born. For cancers of the liver and cervix and, in India/Sri Lanka-born migrants, of the oral cavity, incidence was relatively high in the countries of birth but tended to be lower, nearer Australia-born rates, in the migrants. For these cancers, environmental factors related to the migrant's adopted country, and migrant selection, appeared to have a major effect on the risk of cancer. For certain other cancers, incidence was more similar to that in the countries of birth. Nasopharyngeal cancer, and lung cancer in females, had high rates in both the countries of birth and in migrants to Australia. Nasopharyngeal cancer rates were highest in China/Taiwan and Hong Kong-born migrants, and were also significantly high in migrants from Malaysia/Singapore, Vietnam and the Philippines. Rates of lung cancer were significantly high in women born in China/Taiwan, and the excess was greater for adenocarcinoma than for squamous cell carcinoma. Melanoma had low rates in both the migrants and in the countries of birth. For these cancers, it was probable that genetic factors, or environmental factors acting prior to migration, were important in causation.

Meconium aspiration syndrome and neonatal outcome in a developing country

Malik AS, Hillman D

Ann Trop Paediatr, 1994;14(1):47-51.
PMID: 7516134

The outcome in 148 inborn meconium-stained neonates was studied prospectively over a 5-month period. Fifty-three infants (38.5%) developed meconium aspiration syndrome (MAS). There was a significantly higher rate of MAS (p < 0.001), mechanical ventilation (p < 0.016) and hospital stay (p < 0.016) in neonates with meconium in the trachea than in neonates with no meconium in the oropharynx. The incidence of MAS was significantly higher and the duration of hospital stay longer in outborn than in inborn infants (p < 0.022).

Radical hysterectomy and pelvic lymphadenectomy for early invasive cancer of the cervix - 14-year experience

Sivanesaratnam V, Sen DK, Jayalakshmi P, Ong G

Int. J. Gynecol. Cancer, 1993 Jul;3(4):231-238.
PMID: 11578351

During a 14-year period, 397 radical hysterectomies and pelvic lymphadenectomies were performed for early invasive carcinoma of the cervix. Twenty-one patients were in stage IA2 with lymphatic/vascular channel permeation (5.2%), 340 in stage IB (85.6%) and 34 in early stage 2A disease (8.5%). Eighteen patients (4.5%) were pregnant. Adenocarcinoma comprised 26.9% of cases. The mean operative time was 4.14 h; the intraoperative blood loss was less than 1.51 in 77.3% patients. There was no operative mortality; one patient died 3 weeks after surgery from clostridium difficile enterocilitis. Eleven patients (2.7%) developed venous thrombosis; severe lymphedema occurred in four (1%). The incidence of uretero-vaginal fistula was 0.2% and that of vesico-vaginal fistula 0.5%. Ovarian metastases were noted in 4.3% of cases with adenocarcinoma. Sixty-six patients had positive nodes (16.6%). Five-year survival in patients with more than 2 positive nodes was 68%. The use of adjuvant chemotherapy in patients with 'high risk' factors resulted in survival rates approaching those without risk factors. Neo-adjuvant chemotherapy was used in 10 patients with large bulky tumors; the results were favorable. Recurrences occurred in 47 patients (11.8%); 36 patients have died (9.1%). Age did not appear to influence survival. The overall 5-year survival was 92.2%.

Three cases of human Sarcocystis infection with a review of human muscular sarcocystosis in Malaysia

Pathmanathan R, Kan SP

Trop Geogr Med, 1992 Jan;44(1-2):102-8.
PMID: 1496700

Three cases of muscular sarcocystosis from West Malaysia are reported. The morphological features of the parasites from these three cases are similar to the eight cases previously reported from this country. A review of this total of eleven cases of muscular sarcocystosis showed that they were all incidental findings, where man acted as intermediate hosts of as yet unknown Sarcocystis spp. These cases of muscular sarcocystosis were probably zoonotic in origin and associated with close contact with definitive hosts (both domestic and wild animals) thus permitting the contamination of food and drink with sporocysts shed by these definitive hosts. These infections were probably acquired locally as most of the subjects were born in Malaysia and none had ever left the country to stay elsewhere. Eight of the eleven cases reported were associated with malignancies, especially of the tongue and nasopharynx.

Fulltext Early congenital syphilis--a continuing problem in Malaysia

Lim CT, Koh MT, Sivanesaratnam V

Med J Malaysia, 1995 Jun;50(2):131-5.
PMID: 7565181

Between February 1990 and May 1993, 13 cases of early congenital syphilis (ECS) were managed in the Paediatrics Unit, University Hospital, Kuala Lumpur. Twelve mothers were unbooked with 10 inborn babies. Only one mother had antenatal booking at this hospital but she defaulted antenatal follow-up. Several risk factors associated with ECS were identified: inadequate or no prenatal care (5/13), failure to repeat a serological test for syphilis in the third trimester when it was tested negative at first booking (5/13), sexual promiscuity, substance abuse and a past history of contracting sexually transmitted disease. All 10 mothers who had their serological test repeated at delivery were found to have a positive VDRL and TPHA. Adequate antenatal care early referral of infected, expectant mothers for treatment, and a repeat serological test for syphilis could have prevented these cases of ECS.

Fulltext Pattern of acute rheumatic fever in a local teaching hospital

Omar A

Med J Malaysia, 1995 Jun;50(2):125-30.
PMID: 7565180

Hospital records of children admitted to the department of Paediatrics, University Hospital, Kuala Lumpur, from January 1981 to December 1990, who were diagnosed to have acute rheumatic fever (ARF) were studied. 134 children satisfied the Jones' modified criteria, thus giving a hospital incidence of 21.2/100,000 paediatric admission per year, of which incidence of first attack was 15.8/100,000 per year and recurrent attack was 5.38/100,000 per year. The M:F ratio is 1.39:1. Majority of cases occur in the 6-11 years age group with 6 cases encountered below the age of 5. The Indians had a higher relative risk to develop both the first acute attack as well as recurrences with a relative risk of 2.4 and 4.10 respectively as compared to the Malays. Majority of the patients, irrespective of the ethnic group, came from families with low income.

A study on the menopause in Malaysia

Ismael NN

Maturitas, 1994 Oct;19(3):205-9.
PMID: 7799827

In an attempt to gather data on the menopause in Malaysia, 400 women (13% Chinese, 70% Malays and 16% Indians), representing the three major ethnic groups in Malaysia, were interviewed. The majority (76%) of these women were still married and living with their husbands and 63% of them were working. Most of them (90%) had attained menarche by the age of 15 years and 50% of them had married before the age of 20. Their reproductive record was good, since 76% of them had 3 or more children who were still alive. The mean age at menopause in the Malaysian women studied was 50.7 years. Analysis of the climacteric symptoms reported showed significant differences in the vasomotor and nervosity indices in the perimenopausal and postmenopausal groups. Eighty percent (80%) of the women saw no need to consult a doctor about their climacteric symptoms. When they did, most of them (84%) received medication, but 43% of them did not comply with the prescribed treatment. Dyspareunia and urinary incontinence were evidently regarded as embarrassing complaints in all three groups, since around 80% of the women did not seek medical advice. This is not surprising in view of the fact that 89% of them rated their health as good.

Acute respiratory tract infection: a community-based intervention study in Malaysia

Lye MS, Nair RC, Choo KE, Kaur H, Lai KP

J Trop Pediatr, 1996 06;42(3):138-43.
PMID: 8699578 DOI: 10.1093/tropej/42.3.138

A community-based intervention trial was conducted in Kelantan, Malaysia with the aim of reducing severe acute respiratory tract (ARI) infection in children. Interventions included health education of mothers on childhood pneumonia and training of health staff on case management. In a house-to-house survey 1382 and 1107 children less than 5 years of age in the intervention and control areas, respectively, were followed up every 2 weeks over a 62-week period. The reduction in the incidence of severe ARI cases in the intervention area was significantly greater than in the control area (P < 0.05). The ARI mortality rates were low in both the intervention and control areas ( < 0.1%). Our results indicate that with relatively inexpensive methods and simple interventions, reduction of severe ARI may be effectively achieved. This has important implications for an ARI control programme in Malaysia and other developing countries.

Malaria and filariasis transmission in a village/forest setting in Baram District, Sarawak, Malaysia

Chang MS, Doraisingam P, Hardin S, Nagum N

J Trop Med Hyg, 1995 Jun;98(3):192-8.
PMID: 7783279

Entomological investigations on malaria and bancroftian filariasis transmission were carried out in the endemic area of Baram District, Sarawak. The Anopheles composition, survival and infection rates of malaria and filariasis were compared in the village and 0.5 km from the village ecotype, in forested areas. Anopheles leucosphyrus, An. barbirostris and An. donaldi are the vectors for malaria and bancroftian filariasis in both ecotypes. Biting and infection rates vary, but An. leucosphyrus differed with a peak around midnight in the forested area and soon after dusk in the village setting. The parous rate of An. leucosphyrus was significantly higher in the forest ecotype (P < 0.0001); however, the proportion of 3-parous and older was not overall higher in the forest ecotype (P = 0.68). The entomological inoculation of malaria parasites by An. leucosphyrus was comparatively higher in the forested areas (P > 0.5). The implications of malaria and filariasis transmission in the forested areas in Baram District are discussed.

Fulltext Penang cancer cases reported to the National Cancer Registry of Malaysia, 1987-1990: an epidemiological analysis

Chan CK, Singh J, Rasid BK, Devaraj T

Med J Malaysia, 1994 Jun;49(2):122-31.
PMID: 8090090

2,124 cases of cancer diagnosed and/or treated in Penang between 1987-1990 were reported to the National Cancer Registry of Malaysia by hospitals in Penang. 1,762 met the criteria for Penang incident cases first diagnosed between 1987-1990, and were the subjects on which all subsequent analyses were based. 85 per cent of case notifications were from Mount Miriam Hospital. Among males, all-site cancer incidence rates (age-standardised) were highest among Chinese, and lowest among Malays. Among females, the Indian female incidence rate was highest, higher than that of any other ethnic-gender sub-group. Site-specific cancer rates varied according to ethnicity and gender, but overall the four most frequent cancers reported from Penang were breast, lung, cervix and nasopharynx cancers. It needs to be emphasised that all these results are highly tentative since they are based on notified cancer occurrences and hence are very uncertain proxies for true cancer incidence. Based on incidence rates from the Singapore Cancer Registry (1978-1982), the expected number of incident cases in 1989 for Penang (Malays, Chinese and Indians combined) was 1,561. The number notified to the National Cancer Registry was 496. This underlines the tentative nature of this analysis of the returns for 1987-1990 from Penang.

Fulltext Bacteraemic infections in a neonatal intensive care unit--a nine-month survey

Lim NL, Wong YH, Boo NY, Kasim MS, Chor CY

Med J Malaysia, 1995 Mar;50(1):59-63.
PMID: 7752978

A survey was conducted to determine the rate, outcome, and culture and sensitivity patterns of bacteraemic infections in a large Neonatal Intensive Care Unit (NICU). Over a nine-month period, 136 episodes of infection occurred in 132 (6.9%) out of 1926 admissions. Early onset infection accounted for 35 episodes (25.7%) and was associated with a higher mortality rate compared to late onset infection (45.7% vs 23.8%, p < 0.02). Very low birthweight (VLBW) infants had significantly higher rates of infection (19.4% vs 5.3%, p < 0.001) and mortality (45.2% vs 23.3%, p < 0.02) compared to bigger babies. Gram negative bacilli accounted for 25 early and 90 late isolates while gram positive organisms accounted for 10 early and 16 late isolates. The two main organisms (Acinetobacter and Klebsiella) showed a 69.0 to 85.3% resistance to aminoglycosides and 3rd generation cephalosporins. Ten of 13 isolates of Staphylococcus epidermidis and 3 of 4 Staphylococcus aureus were methicillin resistant. Multiply resistant infections were a major problem in this NICU and efforts to eradicate them needed to be intensified.

Fulltext Bacterial hand infections: an analysis of cases presenting at the University Hospital, Kuala Lumpur

Omar BMI, Sara BTA

Med J Malaysia, 1996 Mar;51(1):23-8.
PMID: 10967975

A significant number of hand infections were found to occur in college students, a group not associated with manual labour. Diabetics did not have a significant delay in recognising the symptoms but have a significant longer period of hospitalisation. The right hand was predominantly involved especially the thumb, index finger and the thenar region. Staphylococcus aureus was the commonest infecting organism.

Duration of oxygen therapy and exchange transfusion as risk factors associated with retinopathy of prematurity in very low birthweight infants

Teoh SL, Boo NY, Ong LC, Nyein MK, Lye MS, Au MK

Eye (Lond), 1995;9 ( Pt 6):733-7.
PMID: 8849541

One hundred and thirteen consecutive infants with a very low birthweight of less than 1500 g were followed prospectively for 6 months to determine the incidence of retinopathy of prematurity (ROP) and associated risk factors. Of this group, 36 (31.9%) infants developed ROP (13 infants had stage 1 ROP, nine had stage 2, six had stage 3, six had stage 4, and two had cicatricial stage ROP). Stepwise logistic regression analysis of various potential risk factors (birthweight, gestation, duration of oxygen therapy, duration of ventilation, highest documented PaO2 and exchange transfusion) showed that only two risk factors were significantly associated with the development of ROP. These risk factors were: the duration of oxygen therapy (p = 0.0005) and exchange transfusion during the neonatal period (odds ratio 5.754, 95% confidence interval 1.002 to 32.997, p = 0.049). The equation of the regression model is: log (odds of developing ROP) = -0.8395 + 0.1447 (OXY)- 0.8750 (ET), where OXY is the duration of oxygen therapy in days, ET = -1 when there was a history of exchange transfusion, and ET = 1 when there was no history of exchange transfusion.

Prevalence of dementia among elderly Chinese and Malay residents of Singapore

Kua EH, Ko SM

Int Psychogeriatr, 1995;7(3):439-46.
PMID: 8821351

This is a comparative study of the prevalence of dementia among elderly Chinese and Malay persons living in the community in Singapore. The subjects, aged 65 years and over, were all living in public housing estates. Two hundred elderly Chinese and 149 elderly Malay persons were interviewed. They were first screened for any cognitive deficit with the Elderly Cognitive Assessment Questionnaire (ECAQ). All those who scored 5 or fewer points on the ECAQ were then assessed with the Geriatric Mental State schedule. The results showed an overall dementia prevalence of 4.0% among the Malay elderly and 2.5% among the Chinese elderly. The rate of dementia of the Alzheimer's type was 1.8% for Chinese women and 1.5% for Malay women; for multi-infarct dementia the rate for Malay women was 4.4% and for Chinese women 0.9%. For Chinese and Malay men, the prevalence of Alzheimer's disease and multi-infarct dementia was quite similar (1.1% and 1.2%).

Fulltext Hydatidiform molar pregnancy in Malaysian women: a histopathological study from the University Hospital, Kuala Lumpur

Cheah PL, Looi LM, Sivanesaratnam V

Malays J Pathol, 1993 Jun;15(1):59-63.
PMID: 8277792

A review of gestational trophoblastic disease diagnosed at the Department of Pathology, University Hospital, Kuala Lumpur from January 1989 to December 1990 using established histological criteria showed 25 complete hydatidiform moles (CHM), 11 partial hydatidiform moles (PHM), 1 invasive mole and 2 choriocarcinoma. The ages of the patients with CHM ranged from 21 to 43 years (mean = 28.5 years) and PHM 20 to 33 years (mean = 27.5 years). The invasive mole occurred in a 42-year-old Malay woman. The two patients with choriocarcinoma were both Chinese and 41 and 46-years old respectively. During the same period, 1,062 non-molar abortions and 13,115 births, inclusive of livebirths and stillbirths were recorded at the University Hospital. The incidence rate of hydatidiform moles was thus estimated to be 1:384 pregnancies. PHM constituted 30% of all molar pregnancies. Hydatidiform moles occurred among the Malays, Chinese and Indians at the rate of 2.43, 2.66 and 3.29 per 1,000 pregnancies respectively. It appears that hydatidiform molar pregnancy has the highest prevalence among the Indians, a finding similar to an earlier Singapore study.

Fulltext Incidence and management of middle ear effusion in cleft palate patients

Lokman S, Loh T, Said H, Omar I

Med J Malaysia, 1992 Mar;47(1):51-5.
PMID: 1387450

For a complete overall rehabilitation of cleft palate patients a multi-disciplinary approach should be adopted. Plastic and Head and Neck Surgeons in whom most of the treatment are entrusted should be concerned not only at achieving palatal function and cosmetic acceptability but also the various other problems associated with cleft palate especially hearing loss. In this study, 66 patients with repaired and unrepaired cleft palates were examined for the presence of hearing loss due to middle ear effusion. The incidence of middle ear effusion was high (57.6%). It was also found that only eight of these patients (12.1%) ever complained of hearing loss or any associated symptoms and repair of the cleft palate did not influence the incidence of middle ear effusion. As such, screening should be done in all cleft palates and otolaryngologists should therefore play an important role in the multi-disciplinary team which should comprise the paediatrician, plastic surgeon, speech therapist, orthodontist and dental specialist.
