Postoperative venous thromboembolism in Asia: a critical appraisal of its incidence

Liew NC, Moissinac K, Gul Y

Asian J Surg, 2003 Jul;26(3):154-8.
PMID: 12925290

Venous thromboembolism (VTE) has historically been perceived to be a rare disorder in Asia. However, new evidence has emerged recently that contradicts this perception. The question of routine VTE prophylaxis has been hotly debated in Asia due to disagreement on its incidence. We reviewed and analysed studies on postoperative VTE in Asian patients to determine if the condition was indeed rare and if the routine prophylactic measures as recommended by internationally accepted guidelines should be adopted in Asia.

Fulltext Hand replantation and revascularization--six years experience in Hospital Kuala Lumpur 1990-1995

Razana A, Hyzan MY, Pathmanathan V, Gill RS

Med J Malaysia, 1998 Sep;53 Suppl A:121-30.
PMID: 10968194

A retrospective study was conducted in 130 patients who underwent replantation or revascularization of 195 amputations in Hand and Microsurgery Unit Hospital Kuala Lumpur from 1990 to 1995. There were 130 patients with 195 amputations in the duration of 6 years study, which were mainly males (111 patients, 85.4%). The commonest age group involved was 19-25 years old (49 cases, 63.7%). There were 146 complete amputations replanted and 49 cases of incomplete amputations were revascularized. The commonest part involved was thumb and index finger (23% of cases each) and majority was caused by industrial accident (60.8%). However in pediatric age group home accident was the leading cause of the amputation (93.8%). The overall survival rate for the amputation was 65.6%. Revascularization had a better survival rate (77.6%) than replantation (61.6%). A clean cut wound and ischaemic time less than 12 hours gave better survival rate. However, there was no significant different chance of survival on distribution of injured parts and ischaemic time (< 12 hours).

Cryopreservation of Citrus madurensis embryonic axes by vitrification: importance of loading and treatment with vitrification solution

Cho EG, Hor YL, Kim HH, Rao VR, Engelmann F

Cryo Letters, 2002 Sep-Oct;23(5):317-24.
PMID: 12447491

This paper investigates the importance of loading and treatment with a vitrification solution on the survival of Citrus madurensis embryonic axes cryopreserved using a vitrification protocol. Among the seven different loading solutions tested, the solution containing 2 M glycerol + 0.4 M sucrose was the most efficient. Of the six vitrification solutions tested, the PVS2 vitrification solution, applied for 20 min at 25 degree C or for 60 min at 0 degree C, ensured the highest survival. A three-step vitrification protocol, involving the treatment of embryonic axes at 0 degree C with half strength PVS2 solution for 20 min then with full strength PVS2 for an additional 40 min was more efficient than a two-step protocol that involved treatment of axes directly with full strength PVS2 solution for 60 min. After rapid immersion in liquid nitrogen, rapid rewarming, unloading in a 1.2 M sucrose solution for 20 min, culture on solid medium with 0.3 M sucrose for 1 day and growth recovery for 4 weeks on standard medium, survival of C. madurensis embryonic axes reached 85 % following the three-step process, compared with 70 % for the two-step process.

Cryopreservation of Citrus madurensis embryonic axes encapsulation-dehydration

Cho EG, Hor YL, Kim HH, Rao VR, Engelmann F

Cryo Letters, 2002 Sep-Oct;23(5):325-32.
PMID: 12447492

In this paper, we demonstrate that C. madurensis embryonic axes can withstand cryopreservation using the encapsulation-dehydration technique. Up to 57.5 % survival was achieved using a standard encapsulation-dehydration protocol, which included pregrowth of encapsulated axes for 16 h in medium containing 0.8 M sucrose + 1 M glycerol, desiccation of beads to around 30 % moisture content (fresh weight basis) followed by rapid freezing. A slightly higher survival percentage (65 %) was obtained using a modified encapsulation-dehydration protocol, which included pretreatment of axes with 2 M glycerol + 0.6 M sucrose for 1 h, concomitantly with their encapsulation in 3 % calcium alginate beads, followed by desiccation of the beads to around 30 % moisture content.

Cryopreservation of Citrus madurensis zygotic embryonic axes by vitrification: importance of pregrowth and preculture conditions

Cho EG, Hor YL, Kim HH, Rao VR, Engelmann F

Cryo Letters, 2001 Nov-Dec;22(6):391-6.
PMID: 11788881

The role of pregrowth and preculture treatments in terms of both medium composition and exposure duration on survival of embryonic axes of Citrus madurensis after cryopreservation using the vitrification procedure was investigated. The optimal pregrowth treatment for excised embryonic axes was a 3-day treatment with 0.1M sucrose. Preculture was also essential in increasing survival after cryopreservation. Among the various media and treatment durations evaluated, a 24h-preculture of embryonic axes on medium with 0.3M sucrose and 0.5M glycerol was found to be optimal. Using these pregrowth and preculture conditions followed by treatment at 25 degrees C for 20 min each with a loading solution (0.4M sucrose + 2.0M glycerol) and then the PVS2 vitrification solution, direct immersion in liquid nitrogen, rapid rewarming, unloading in a 1.2M sucrose solution for 20 min and transfer of embryonic axes on recovery medium, 82.5% survival and regrowth without intermediary callus formation were obtained with C. madurensis embryonic axes.

Lim TO, Lim YN, Wong HS, Ahmad G, Singam TS, Morad Z, et al.

Med J Malaysia, 1999 Dec;54(4):459-70.
PMID: 11072463

We describe the outcomes on haemodialysis (HD) and continuous ambulatory peritoneal dialysis (CAPD) provided by the Ministry of Health (MOH). The assessment was based on data from the Malaysian Dialysis Registry on 2480 HD and 732 CAPD patients who commenced dialysis between 1980 and 1996. Young patients (age < 40) have remarkable long term survival (life expectancies of 16 years on HD, 18 years on CAPD). Adjusting for background mortality, relative survival of older patients was as good as younger ones. Diabetics did poorly. 52% of HD and 26% of CAPD patients were employed in 1996. 71% of HD patients scored 10(normal) on QL index (a measure of quality of life) while 60% of CAPD patients have similar score. Differences in rehabilitation and QL index scores by age, gender and diabetes were also observed. Outcomes of dialysis in the MOH programme are reassuring.

Early cranial ultrasound changes as predictors of outcome during first year of life in term infants with perinatal asphyxia

Boo NY, Chandran V, Zulfiqar MA, Zamratol SM, Nyein MK, Haliza MS, et al.

J Paediatr Child Health, 2000 Aug;36(4):363-9.
PMID: 10940172

OBJECTIVES: To identify the types of early cranial ultrasound changes that were significant predictors of adverse outcome during the first year of life in asphyxiated term infants.
METHODOLOGY: This was a prospective cohort study. Shortly after birth, cranial ultrasonography was carried out via the anterior fontanelles of 70 normal control infants and 104 asphyxiated infants with a history of fetal distress and Apgar scores of less than 6 at 1 and 5 min of life, or requiring endotracheal intubation and manual intermittent positive pressure ventilation for at least 5 min after birth. Neurodevelopmental assessment was carried out on the survivors at 1 year of age.
RESULTS: Abnormal cranial ultrasound changes were detected in a significantly higher proportion (79.8%, or n = 83) of asphyxiated infants than controls (39.5%, or n = 30) (P < 0.0001). However, logistic regression analysis showed that only three factors were significantly associated with adverse outcome at 1 year of life among the asphyxiated infants. These were: (i) decreasing birthweight (for every additional gram of increase in birthweight, adjusted odds ratio (OR) = 0.999, 95% confidence interval (CI) 0.998, 1.000; P = 0.047); (ii) a history of receiving ventilatory support during the neonatal period (adjusted OR = 8.3; 95%CI 2.4, 28.9; P = 0.0009); and (iii) hypoxic-ischaemic encephalopathy stage 2 or 3 (adjusted OR = 5.8; 95%CI 1.8, 18.6; P = 0.003). None of the early cranial ultrasound changes was a significant predictor.
CONCLUSIONS: Early cranial ultrasound findings, although common in asphyxiated infants, were not significant predictors of adverse outcome during the first year of life in asphyxiated term infants.

The effect of bradykinin and its antagonist on survival time after coronary artery occlusion in hypertensive rats

Abbas SA, Sharma JN, Yusof AP

Immunopharmacology, 1999 Oct 15;44(1-2):93-8.
PMID: 10604530

It is known that BK does play a role in the cardioprotective effect of angiotensin converting enzyme (ACE) inhibitors. The present study therefore was conducted to examine the effects of bradykinin (BK) and its antagonist on survival time in spontaneously hypertensive rats (SHR) with coronary artery ligation for 15 min and continuously. We also evaluated the heart rate and blood pressure (BP) in the presence and absence of BK and BK2 receptor antagonist, D-Arg-[Hyp-D-Phe7]BK. Coronary artery was ligated in anaesthetized rats and they were artificially ventilated with room air (stroke volume, 4 ml; 48 strokes/min) as described by the previous investigators. Lead II elecrocardiogram (ECG) was recorded from subcutaneous steel needle electrodes. Results of this investigation indicated that BK treatment 4 microg/kg (i.v.) and 8 microg/kg (i.v.) caused significant (P < 0.05) increase in survival time in SHR with coronary artery ligation for 15 min and continuously as compare to their respective saline-treated controls. However, BK antagonist treatment 4 microg/kg (i.v.) abolished the increase in survival time caused by BK treatment. The mean values of survival time between the saline-treated and BK antagonist plus BK-treated rats did not differ significantly (P > 0.05). The heart rate and BP responses were greatly reduced (P < 0.001) in the presence of coronary artery ligation. These findings suggest that BK might have cardioprotective effect to increase the survival time in rats by activating BK2 receptors after coronary artery ligation.

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%.

SLE mortality in an oriental population

Koh ET, Seow A, Leong KH, Chng HH

Lupus, 1997;6(1):27-31.
PMID: 9116715 DOI: 10.1177/096120339700600104

We analysed the causes of 67 deaths, over a 4 y period, in our oriental population with systemic lupus erythematosus (SLE). The median disease duration was 48 +/- 60.5 months (range 1-250 months). The mean age at diagnosis and death were 30 and 35.1 y respectively. SLE alone accounted for death in 30 patients (44.8%), infection in 27 (40.3%), pulmonary embolism in 5 (7.5%), malignancy in 4 (5.9%) and rheumatic heart disease in 1 (1.5%). The major organ involvement in those with active disease at death were SLE related thrombocytopenia (n = 23/44, 52.3%), nephritis (n = 21/44), 47.7%), cerebral lupus (n = 16/44, 36.4%), and pulmonary haemorrhage (n = 12/44, 27.3%). As in other series, SLE and infection were the principal causes of death in our population. During this 4 y period, there was no late death due to atherosclerosis.

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.

Economic and cultural influences on the decision to leave home in Peninsular Malaysia

Johnson RW, DaVanzo J

Demography, 1998 Feb;35(1):97-114.
PMID: 9512913

Although the departure of children from the parental home is an important life-cycle event, few studies have investigated nest-leaving in developing countries. Using retrospective data from the Second Malaysian Family Life Survey, we estimate hazard models of nest-leaving in Peninsular Malaysia. We find that the departure of children, especially sons, responds to economic incentives, including housing costs, family businesses, education, and economic growth, and that ethnic differences in nest-leaving are important. We also find that the median age of departure from home has declined sharply over the past 40 years, a period of rapid social and economic change in Malaysia.

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.

Clear cell sarcoma of kidney: a clinicopathological study of eight cases from Malaysia

Cheah PL, Looi LM, Lin HP

Histopathology, 1992 Oct;21(4):365-9.
PMID: 1328018

Eight cases of clear cell sarcoma of kidney were seen in the Department of Pathology, University Hospital, Kuala Lumpur, Malaysia over the 16-year period from 1973 to 1989. Five of the patients were males. Six patients were Malay, one Chinese and one Indian. The patients' ages ranged from 8 months to 3 years. Clear cell sarcoma was the original diagnosis in two patients while six were diagnosed as blastemal-predominant Wilms' tumours at presentation. Metastases developed in five patients. Metastatic sites included the thoracic vertebra, skull, orbit, humerus, radius, ulna, shoulder, lung and liver. The prolonged survival, of 9 years and 9 months, seen in one patient despite omission of Adriamycin (doxorubicin) from the chemotherapeutic protocol is highlighted. We also emphasise the histological factors which are of help in differentiating clear cell sarcoma from Wilms' tumour.

Biosocial variances and infant survival: a path analysis approach

Frisch AS, Kallen DJ, Griffore RJ, Dolanski EA

J Biosoc Sci, 1992 Apr;24(2):175-83.
PMID: 1583032

This study used path analysis to assess the chances of survival of babies in a neonatal intensive care unit in Lansing, Michigan, USA. Two paths to neonatal survival were identified and the variables accounted for 20% of the variance in gestational age. The first path showed that prior infant losses were negatively correlated with gestational age while in the second path, gestational age showed negative relationships with pre-pregnancy weight and household job worries.

Prognostic significance of retinopathy at presentation in adult acute leukemia

Reddy SC, Quah SH, Low HC, Jackson N

Ann Hematol, 1998 Jan;76(1):15-8.
PMID: 9486919

Retinal changes are common in adult acute leukemia patients at presentation, but their prognostic significance is controversial. A 5-year study has been carried out with newly diagnosed acute leukemia patients aged 12-77 years. Seventy-seven cases (49 AML, 28 ALL) were studied prospectively for the presence of intraretinal hemorrhages (IRH), white-centered hemorrhages, cotton-wool spots, and macular hemorrhages. They were treated according to standard chemotherapy protocols, and then achievement of complete remission (CR) and the duration of overall survival (OS) were compared between the groups with and without these different retinal features. No association was found between the presence of any retinal abnormality and CR induction rate, although there was a trend to a lower CR rate among patients with IRH. The median OS of those with IRH was 72 days, compared with 345 days among those without IRH (p=0.002). A WBC at presentation greater than 50x10(9)/l and age greater than 40 years were also associated with shorter OS (p<0.0001 and p=0.0045, respectively). However, after regression analysis, IRH remained statistically significant as a poor prognostic indicator (p=0.01). We conclude that the presence of IRH is an indicator of poor prognosis in acute leukemia.

Inhibition of macromolecular synthesis in cultured macrophages by Pseudomonas pseudomallei exotoxin

Mohamed R, Nathan S, Embi N, Razak N, Ismail G

Microbiol. Immunol., 1989;33(10):811-20.
PMID: 2615673

Pseudomonas pseudomallei exotoxin was found to be a potent inhibitor of protein and DNA synthesis in cultured macrophages. Inhibition of DNA synthesis occurred at toxin concentrations as low as 1-2 micrograms/ml and inhibition of 3H-thymidine uptake was almost complete at concentrations of 8 micrograms/ml or more. A close correlation between cell damage and inhibition by DNA synthesis was observed. For protein synthesis, inhibition was obtained at much lower doses (0.06-2.0 micrograms/ml) of the toxin. At similar toxin concentrations, DNA synthesis was marginally affected. Further, it was shown that protein synthesis inhibition occurred almost immediately after incubation, reaching its maximal inhibitory effect of 70% after 6 hr. DNA synthesis, however, was minimally affected by a similar toxin concentration even after 10 hr of incubation. The inhibition of macromolecular synthesis in macrophages by P. pseudomallei exotoxin may be relevant to its modulatory effect on the host defense mechanism.

Choo KE, Ariffin WA, Ahmad T, Lim WL, Gururaj AK

Ann Trop Paediatr, 1990 Mar;10(1):89-98.
PMID: 1694651

A 2.5-year retrospective study of pyogenic meningitis in hospitalized children in Kelantan was carried out with regard to aetiology, clinical features, investigation, treatment and outcome. There were 58 children with 43 cases (74.1%) occurring below the age of 1 year. Frequent presenting symptoms included fever (98.3%), fits (77.6%), anorexia (39.7%), vomiting (34.5%) and drowsiness (12.1%). On admission, 37 (63.7%) had neck stiffness, 10 (17.2%) had Kernig's sign and 32 (55.2%) had coma. CSF cultures were positive for Haemophilus influenzae in 29 (50%), Streptococcus pneumonia in 13 (22.4%) and Neisseria meningitidis in 3 (5.2%). The antibiotic sensitivity profiles showed that the three main organisms were 100% sensitive to Chloramphenicol, Streptococcus pneumoniae was 100% sensitive to penicillin, Neisseria meningitidis was 100% sensitive to penicillin and ampicillin, and Haemophilus influenzae was 90% sensitive to penicillin and ampicillin. The total hospital mortality was 18.9%. All but two of the eleven deaths occurred in children younger than 1 year. Nineteen of the 35 (54.3%) survivors attended for at least one follow-up after discharge from hospital. Of these 19 children, 47.4% had neurological sequelae.
