Abstract
We established a Web-based programme called the ‘Wellness Online Program’ or WOLP. The programme runs for six weeks. It aims to help individuals manage their own wellness regardless of geographical location. WOLP is based on a holistic approach to health and consists of six wellness dimensions: physical (exercise and diet), emotional, social, intellectual, spiritual and occupational. A total of 150 volunteers from the general public were recruited online for this study and data were collected at three intervals: at the beginning of the programme (week 1), mid-programme (week 3) and at the end of the programme (week 6). Ninety of the participants (60%) completed the six-week programme. Acceptance of WOLP, measured by the frequency of individual usage, increased from the start to the end of the programme. Overall personal wellness management improved after six weeks on the wellness programme (5–10%). The study shows that personal wellness management, which had been demonstrated in the narrower confines of the corporate sector, is also possible in the public domain.

Abstract
The aim of this study was to estimate conversion coefficients for maximum entrance skin dose (MESD) and effective dose (E) for patients undergoing transcatheter aortic valve implantation (TAVI) and to evaluate the risk of exposure-induced cancer death (REID) for prospectively younger patients. Effective doses and risks were estimated for 22 patients using PCXMC whereas MESDs were estimated for a sub-group of 15 patients using Gafchromic film. The estimated conversion coefficients for skin dose [CCS = MESD/dose-area product (DAP)] and E (CCE = E/DAP) were 9.7±1.5 and 0.24±0.02 mSv/Gy cm(2), respectively. The REID ranged from 1:9900 to 1:1400 and by decreasing the age of examination to 40-50 y of age, the REID increased with a factor of 2 for females and 1.5 for males. The organ at risk was the lung. Currently, the patient population is elderly with radiation-induced skin injuries as the main risk. The risk of cancer induction should additionally be considered if younger patient populations are to be treated.

Abstract
PURPOSE To report the outcomes of gestational trophoblastic neoplasia (GTN) at a single institution and to determine the factors affecting response to chemotherapy and survival. METHODS/PATIENTS From 1979-2010, we retrospectively reviewed the data of 221 patients treated at our center. GTN Patients were assigned to low-risk (score ≤6) or high-risk (score ≥7) based on the WHO risk factor scoring system. Overall survival (OS) probabilities were estimated using Kaplan-Meier method. Logistic regression was applied to study the impact of different factors on the response to initial therapy. RESULTS Patients' OS rate was 97 %. Median age at diagnosis was 37 year. 131 (59 %) patients had low-risk and 88 (40 %) cases had high-risk GTN. Complete remission rates to initial chemotherapy in low-risk group were 53 % and 87 % for single-agent methotrexate or dactinomycin, respectively. In high-risk group, 94 % achieved complete remission to initial chemotherapy with etoposide, methotrexate, dactinomycin, cyclophosphamide, and vincristine (EMA-CO). Etoposide, cisplatin, and dactinomycin as primary therapy in high-risk patients was successful in 70 %, while bleomycin, etoposide, and cisplatin (BEP) was successful in 53 % of cases. Salvage chemotherapy, surgical intervention or radiation therapy resulted in overall complete remission of 90 % in low-risk and 73 % in high-risk groups. Factors associated with resistance to initial chemotherapy were advanced-stage III/IV (p = 0.005), metastatic site other than lung or vagina (p = 0.005) and high-risk prognostic score (p = 0.05). OS was significantly influenced by the type of antecedent pregnancy (molar 98 % vs. others 93 %; p = 0.04), FIGO stage (I, II 100 % vs. III, IV 94 %; p = 0.02), score (low-risk 100 % vs. high-risk 92 %; p = 0.01), and site of metastasis (lung/vagina 98 % vs. others 85 %; p = 0.002). CONCLUSIONS GTNs have excellent prognosis if properly treated at experienced centers. Single-agent dactinomycin seems more effective for low-risk GTN. EMA-CO remains the preferred primary treatment regimen for high-risk group. The excellent outcome reflects the success of salvage therapy.

Abstract
The MBEC™ Physiology & Genetics Assay recently became the first approved ASTM standardized biofilm disinfectant efficacy test method. This report summarizes the results of the standardization process using Pseudomonas aeruginosa biofilms. Initial ruggedness testing of the MBEC method suggests that the assay is rugged (i.e., insensitive) to small changes to the protocol with respect to 4 factors: incubation time of the bacteria (when varied from 16 to 18h), treatment temperature (20-24°C), sonication duration (25-35min), and sonication power (130-480W). In order to assess the repeatability of MBEC results across multiple tests in the same laboratory and the reproducibility across multiple labs, an 8-lab study was conducted in which 8 concentrations of each of 3 disinfectants (a non-chlorine oxidizer, a phenolic, and a quaternary ammonium compound) were applied to biofilms using the MBEC method. The repeatability and reproducibility of the untreated control biofilms were acceptable, as indicated by small repeatability and reproducibility standard deviations (SD) (0.33 and 0.67 log10(CFU/mm(2)), respectively). The repeatability SDs of the biofilm log reductions after application of the 24 concentration and disinfectant combinations ranged from 0.22 to 1.61, and the reproducibility SDs ranged from 0.27 to 1.70. In addition, for each of the 3 disinfectant types considered, the assay was statistically significantly responsive to the increasing treatment concentrations.

Abstract
Pneumonia is common among critically ill burn patients and is a major cause of morbidity and mortality among them. Prediction of mortality in patients with severe burns remains unreliable. The aim of this research is to study the incidence, early diagnosis and management of nosocomial pneumonia, and to discuss the relationship between pneumonia and death in burn patients. This prospective study was carried out on 80 burn patients (35 males and 45 females) admitted to Menoufiya University Hospital Burn Center and Chest Department, Egypt, from September 2011 to March 2012. Our findings showed an overall burn patient mortality rate of 26.25 % (21/80), 15% (12/80) incidence of pneumonia, and a 50% (6/12) mortality rate among patients with pneumonia compared to 22 % (15/68) for those without pneumonia. The incidence of pneumonia was twice as high in the subset of patients with inhalation injury as among those without inhalation injury (P< 0.001). It was found that the presence of pneumonia, inhalation injury, increased burn size, and advanced age were all associated with increased mortality (P< 0.001). In the late onset pneumonia, other associated factors also contributed to mortality. Severity of disease, severity of illness (APACHE score), organ failure, underlying co-morbidities, and VAP PIRO score all have significant correlations with mortality rate. Pneumonia was an important factor for predicting burn patient mortality. Early detection and management of pneumonia are absolutely essential.

Abstract
We study the temperature dependent Ce 4f spectral evolution of a well known Kondo system, CeAl2, for a range extending beyond 2 eV below the Fermi level, using photoemission spectroscopy. Interestingly, the spectral evolution is inconsistent with the predictions of the many-body spectral function calculations corresponding to the Kondo resonance interpretation of the screened Ce 4f photoemission features. In order to explain our spectral evolution we propose the phenomenon of collapse of the Kondo singlet wavefunction upon photoelectron kinetic energy measurement. Our proposal suggests that the screened final states in photoemission spectroscopy are not quantum states.

Abstract
The research suggests that adiponectin plays an important role in sensitizing insulin action. It is interesting to find that the lower levels of adiponectin exist in the plasma of obese and Type 2 diabetes subjects and in the adipose tissue of obese, db/db mice, and insulin-resistant individuals. However, the underlying mechanism by which adiponectin expression is inhibited remains largely unknown. In this study, we reported that adipogenesis was inhibited by the stable over-expression of protein kinase C θ (PKCθ) in 3T3-L1 pre - adipocytes. The prolonged treatment of mature 3T3-L1 adipocytes with palmitate, a kind of saturated free fatty acid, reduced adiponectin expression at both mRNA level and protein level, accompanied with the enhanced phosphorylation of PKCθ and extracellular signal-regulated kinase (ERK), and the impaired expression of peroxisome proliferator-activated receptor γ2 (PPARγ2) mRNA. Either PD98059, an ERK inhibitor or PKCθ pseudosubstrate, a specific PKCθ inhibitor, restored palmiate-inhibited PPARγ2 mRNA expression and subsequent adiponectin expression. In addition, the over-expression or activation of PKCθ resulted in the enhanced phosphorylation of ERK in the mature 3T3-L1 adipocytes. PKCθ pseudosubstrate significantly reduced the phorbol 3-myristate 12-acetate (PMA)-induced phosphorylation of ERK. The data suggested that PKCθ-dependent activity of ERK resulted in the impaired expression of PPARγ2 mRNA leading to the reduction of adiponectin expression in the mature 3T3-L1 adipocytes.

Abstract
A study in Egypt determined the prevalence of hepatitis B and C virus infections among barbers (n = 308) and their clients (n = 308) in Gharbia governorate, and assessed knowledge, attitude and practices during hair-cutting and shaving. HBsAg was detected among 4.2% of barbers and 3.9% of clients (more urban than rural). Anti-HC antibodies were detected in 12.3% of barbers and 12.7% of clients. HCV-RNA prevalence was 9.1% among both barbers and clients (more rural than urban). Knowledge was high among the majority of participants and good practices during shaving and hair-cutting were observed for the majority of barbers. Barbers appeared to have no job-related risk of acquiring viral hepatitis.

Abstract
OBJECTIVE To document the socio-demographic characteristics and psychiatric profiles of the survivors of the Nairobi United States Embassy terrorist bomb blast referred to a psychiatric and psychotherapy (counselling) service. METHOD This was a descriptive cross-sectional study. Clinical interviews and structured questionnaires for post-traumatic stress disorder (PTSD) and stress were administered. Survivors of the bomb blast referred to a psychiatric and psychotherapy service one year or more after the bombing were included in the study. These survivors had been treated using psychopharmacotherapy and individualised (not group) therapy/counselling. RESULTS Eighty-three consecutive referrals to a psychiatric service participated in this study. There were more males and the sample was generally well educated. The referrals made contact with the referring agency for a number of reasons including seeking psychological, financial and medical assistance. All the patients reported varying degrees of psychiatric symptoms and functional impairment on various aspects of social occupational functioning. High scores for PTSD and other related stress were recorded one or more years after the bombing. CONCLUSION Although the survivors indicated that initial counselling following the blast had helped them, they still scored high on PTSD suggesting that clinically, the initial counselling had little, if any impact on the development of PTSD. There is need for a holistic approach to the management of psychotrauma in individuals.

Abstract
2016 Background: Glioblastoma multiforme (GBM) is the most common and aggressive primary brain tumor. Current standard treatment consists of fractionated radiotherapy (RT) with daily oral temozolomide (TMZ) chemotherapy followed by 6 months of adjuvant TMZ chemotherapy. Median survival is 14.3 months. Because GBM is characterized by vascular proliferation and produces high levels of vascular endothelial growth factor (VEGF), attempts to better control the disease with targeted anti-angiogenesis therapies are underway. Here, we report preliminary safety and tolerability data of bevacizumab (BV) when added to monthly TMZ chemotherapy. Methods: Subjects received standard regional RT to a dose of 60 Gy in 30 fractions with dailyconcurrent TMZ (75 mg/m2) within 3–5 weeks of diagnosis. Four weeks after RT/TMZ, subjects received 5 consecutive daily TMZ doses (150–200 mg/m2) administered every 28 days. BV (10mg/kg) was given every 14 days. Treatment continued until either disease progression or unacceptable toxicity occurred. Results: 42 of 48 planned subjects were enrolled as of 12/30/08. Twenty-three remained on study. Of these, 4 were receiving RT/TMZ, 18 were receiving TMZ/BV and 1 was delayed post-RT/TMZ due to local wound infection. Nineteen were off-study. Eleven of those off-study never received BV due to: study withdrawal (n = 2), toxicity during RT/TMZ (n = 3) and post-RT/TMZ progression (n = 6). Seven subjects progressed while receiving TMZ/BV. Twenty-six of the 42 enrolled received at least one 28-day cycle of TMZ/BV (range 1 - 16 cycles). Duration of treatment, inclusive of RT/TMZ, ranged from 27 to 523 days. Best radiographic responses of evaluable subjects, using MacDonald criteria were: 5 complete, 9 partial, 13 stable and 7 progressive disease. Of those taken off study, 13 were due to disease progression. Of those removed from study due to toxicity, none were unexpected and only 1 (a GI bleed) occurred during the TMZ/BV phase. A statistical analysis of response and survival is pending. Conclusions: The co-administration of TMZ/BV following RT/TMZ for newly diagnosed GBM is safe and well-tolerated. [Table: see text]

[PMID: 18589133 DOI: 10.1016/j.transproceed.2008.03.085] [Citation(s) in RCA: 11] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2007] [Revised: 12/14/2007] [Accepted: 03/06/2008] [Indexed: 11/18/2022]
Abstract
BACKGROUND Hepatitis C virus (HCV) recurrence after living donor liver transplantation (LDLT) represents a challenging issue due to universal viral recurrence and invasion into the graft, although the incidence of histological recurrence, risk factors, and survival rates are still controversial. PATIENTS AND METHODS Recurrence of HCV was studied in 38 of 53 adult patients who underwent LDLT. RESULTS Recipient and graft survivals were 86.6% at the end of the follow-up which was comparable to literature reports for deceased donor liver transplantation (DDLT). Clinical HCV recurrence was observed in 10/38 patients (26.3%). Four patients developed mild fibrosis with a mean fibrosis score of 0.6 and mean grade of histological activity index (HAI) of 7.1. None of the recipients developed allograft cirrhosis during the mean follow-up period of 16 +/- 8.18 months (range, 4-35 months). Estimated and actual graft volumes were negatively correlated with the incidence and early clinical HCV recurrence. None of the other risk factors were significantly correlated with clinical HCV recurrence: gender, donor and recipient ages, pretransplantation Child-Pugh or model for end-stage liver disease (MELD) scores, pre- and postoperative viremia, immunosuppressive drugs, pulse steroid therapy, and preoperative anti-HBc status. CONCLUSIONS Postoperative patient and graft survival rates for HCV (genotype 4)-related cirrhosis were more or less comparable to DDLT reported in the literature. Clinical HCV recurrence after LDLT in our study was low. Small graft volume was a significant risk factor for HCV recurrence. A longer follow-up and a larger number of patients are required to clarify these issues.

Abstract
A 56-year-old male presented with a history of right loin pain of two months duration. Physical examination showed a firm non-tender mass in the left upper quadrant. Blood and urinary investigations including serum Cortisol and urinary cathecholamines were normal. CT scan showed an oval, welldefined, heterogeneous mass measuring 14-10 cm. in the region of the left suprarenal gland(Fig. 1).There was no evidence of infiltration into the surrounding tissue. In view of the size and supra-renal location of the mass it was decided to remove the retroperitoneal tumor and the ipsilateral adrenal gland through a left thoraco-abdominal incision to permit adequate exposure and vascular control.

Abstract
OBJECTIVES The effect of economic status (ES) on growth, insulin-like growth factor (IGF)-I and IGF-binding protein (IGFBP)-3 in healthy children is not well characterized. We aimed to study the interrelationship between height, weight, IGF-I, IGFBP-3, mid-parental height (MPH) and ES. DESIGN/SUBJECTS Eight hundred and fourteen healthy children (428 boys, 386 girls; age 3-18 years) were classified according to income of the families as low, middle and high. Standard deviation scores (SDSs) of height, weight, MPH, IGF-I and IGFBP-3 were compared between the groups. The combined effect of these parameters and ES on height SDS was investigated with complex statistical models. RESULTS There was a significant trend for height and weight SDSs to increase with higher income levels in boys, but not in girls. Body mass index (BMI) SDSs were similar in three groups. There was a general trend for MPH SDS to increase with income levels in both sexes. In boys, IGF-I SDS was significantly higher in high ES group than low ES. In girls, IGFBP-3 SDSs were significantly higher in high ES group than in middle ES group. For both genders, height SDS was highly correlated with weight SDS and moderately correlated with BMI SDS, MPH SDS and IGF-1 SDS. All correlations were significant and positive. Complex models showed that MPH (19%), IGF-I (13%) and ES (3%) in boys, and MPH (16%) and IGF-I (7%) in girls have significant contribution to height SDSs. CONCLUSIONS ES per se, independent of overt malnutrition, affects height, weight, IGF-I and IGFBP-3 with some gender differences in healthy children. Influence of income on height and weight show sexual dimorphism, a slight but significant effect is observed only in boys. MPH is the most prominent variable effecting height in healthy children. Higher height and MPH SDSs observed in higher income groups suggest that secular trend in growth still exists, at least in boys, in a country of favorable economic development.

Abstract
OBJECTIVES To profile and quantify the psychometric properties of the NOK (Ndetei-Othieno-Kathuku) scale against internationally used Gold-standards and benchmarks for mild psychiatric disorders and post-traumatic stress disorders and to provide a potential easy to administer culture sensitive instrument for screening and assessing those with possible psychiatric disorders for the Kenyan and similar social-cultural situations. DESIGN Cross-Sectional quantitative study. SETTING A psychiatric clinical consultation setting and Kyanguli Secondary School psychotrauma counselling clinical set-up. SUBJECTS Survivors of the Nairobi USA Embassy bombing who were referred for psychiatric treatment and survivors of a fire disaster from a rural Kenyan school (Kyanguli School fire disaster) including students, parents of the diseased children and staff members. RESULTS Positive correlation was found between the NOK and all the instruments. The highest correlations were between the NOK and the BDI and SCL-90 (r = 0.557 to 0.786). The differences between the NOK scores among the different groups were statistically significant (F ratio = 13.54 to 160.34, p < 0.01). The reliability coefficient (internal consistency) of the scale, alpha = 0.9733. Other item statistics and correlations of the scale are discussed. CONCLUSION It is concluded that the NOK has high concurrent and discriminant validity as well as a high internal consistency and that it can be used for the rapid assessment of psychotrauma victims of all age groups; and stress in general in similar age groups in the local setting. It is culture appropriate and sensitive.

Abstract
INTRODUCTION AND OBJECTIVES Living donor liver transplantation (LDLT) is an alternative source of organs for patients with end-stage liver disease (ESLD) in absence of deceased donor LT. In LDLT the greatest concern is donor safety. Our objective was to evaluate the outcome of donors after right lobe liver donation in a single LT center in Egypt. PATIENTS AND METHODS Fifty LDL resections were performed from 2001 to 2004. The mean donor age was 29.2 +/- 6.4 years. Residual liver volume was 41.1 +/- 4.5%. Mean operative time was 560 +/- 62.2 minutes; mean ICU stay, less than 24 hours; mean hospital stay, 15.4 +/- 7.7 days; and mean follow-up period, 6 months. RESULTS There was no mortality. The overall complication rate was 68% (34 donors). Major complications included intraoperative bleeding in one, biliary leak in two, and pneumonia in three donors. Minor complications included mild pleural effusion in 13 donors, transient ascites in 10, mild depression in 7, intra-abdominal collections in 3, and wound infections in 1 donor. Residual liver volume did not affect the complication rate. None required reoperation. Return to predonation activity occurred within 6 to 8 weeks. No liver impairment occurred during follow-up. CONCLUSION Right lobe adult LDLT is a safe procedure with regard to donor outcome. Major complications occurred in only 10% of our series.

Abstract
Mammalian thalamus is a critical site where early perception of sensorimotor signals is dynamically regulated by acetylcholine in a behavioral state-dependent manner. In this study, we examined how synaptic transmission is modulated by acetylcholine in auditory thalamus where sensory relay neurons form parallel lemniscal and nonlemniscal pathways. The former mediates tonotopic relay of acoustic signals, whereas the latter is involved in detecting and transmitting auditory cues of behavioral relevance. We report here that activation of cholinergic muscarinic receptors had opposite membrane effects on these parallel synaptic pathways. In lemniscal neurons, muscarine induced a sustained membrane depolarization and tonic firing by closing a linear K(+) conductance. In contrast, in nonlemniscal neurons, muscarine evoked a membrane hyperpolarization by opening a voltage-independent K(+) conductance. Depending on the level of membrane hyperpolarization and the strength of local synaptic input, nonlemniscal neurons were either suppressed or selectively engaged in detecting and transmitting synchronized synaptic input by firing a high-frequency spike burst. Immunohistochemical and Western blotting experiments showed that nonlemniscal neurons predominantly expressed M2 muscarinic receptors, whereas lemniscal cells had a significantly higher level of M1 receptors. Our data indicate that cholinergic modulation in the thalamus is pathway-specific. Enhanced cholinergic tone during behavioral arousal or attention may render synaptic transmission in nonlemniscal thalamus highly sensitive to the context of local synaptic activities.

Abstract
OBJECTIVE The present study aimed to investigate the extent to which recurrent abdominal pain and other factors were associated with academic achievement among Year-6 (12 years of age) schoolchildren. METHODS The present study was a cross-sectional survey conducted from September to November 2001. Schoolchildren were recruited from primary schools that were selected randomly from a list of all primary schools in Petaling Jaya, Malaysia, using random sampling numbers. Information concerning recurrent abdominal pain, socio-economic status, life events, demographic and other details was obtained using a combination of questionnaires and interviews. Academic achievement was assessed using a score based on the Malaysian Primary School Achievement Examination. An overall score at or above the mean was taken to indicate high academic achievement while a score below the mean indicated poor academic achievement. RESULTS A total of 1971 children were studied (958 boys and 1013 girls: 1047 Malays, 513 Chinese and 411 Indians). Of these children, 456 (23.1%) fulfilled the criteria for recurrent abdominal pain. Using the method of binary logistic regression analysis, the following factors were found to be independently associated with poor academic performance: a low socio-economic status (odds ratio (OR) 1.30; 95% confidence interval (CI) 1.25-1.35); male sex (OR 1.61; 95% CI 1.26-2.05); the death of a close relative (OR 2.22; 95% CI 1.73-2.85); the divorce or separation of parents (OR 3.05; 95% CI 1.73-5.40); the commencement of work by the mother (OR 1.34; 95% CI 1.02-1.76); hospitalization of the child in the 12 months prior to the study (OR 1.83; 95% CI 1.12-3.01); lack of health-care consultation (OR 1.80; 95% CI 1.36-2.36); missing breakfast (OR 1.47; 95% CI 1.07-2.02); and lack of kindergarten education (OR 1.35; 95% CI 1.04-1.75). CONCLUSIONS Many factors, such as socio-economic status and recent life events, were associated with poor academic performance. Recurrent abdominal pain did not correlate directly to academic performance. Stress may be a means by which various factors cause children to struggle academically.

Abstract
BACKGROUND Nanofiltration has proven to be an effective technology for virus removal. The small nonenveloped viruses, such as HAV and parvovirus B19 (B19), are evidently more difficult to remove than the larger enveloped viruses. However, since antibodies against these viruses, HAV and B19, are constantly present in large plasma pools, it is conceivable that antibody binding will lead to an increase in size of the viruses due to a corona of antibodies on the virus surfaces. These enlarged viruses should be easier to remove by nanofiltration than naked viruses. In this study, antibody-coated viruses and free virions were subjected to nanofiltration to determine whether the antibody-mediated increase in size contributes to the elimination of viruses which are otherwise too small to be retained by filters of a given nominal pore diameter. STUDY DESIGN AND METHODS One-percent IgG or 1-percent albumin solutions were spiked with bovine enterovirus (BEV) and filtered through 50-nm filters. This virus cross-reacts with antibodies in pooled human IgG solutions but persists as free virions in albumin solutions. Similarly, two parvoviruses, bovine parvovirus (BPV) and minute virus of mice (MVM), in 1-percent IgG solutions were filtered through 20-nm filters. BPV cross-reacts with antibodies in human IgG, whereas MVM remains unaffected. Virus removal was assessed by in vitro infectivity assays. Two methods were developed to displace the antibodies from BEV and BPV and thereby render them accessible for titration. RESULTS Antibody-coated BEV was eliminated to below detection limit by the 50-nm filters (logarithmic reduction factors [LRF] > or = 5), while free BEV virions passed without restraint through the same filters. Similarly, antibody-coated BPV was completely retained by the 20-nm filters (LRF > or = 5). MVM virions were strongly retained by the 20-nm filters; however, the virus was still detectable in the filtrate. CONCLUSION These results indicate that viruses with bound antibodies are efficiently eliminated by nanofiltration by use of filters having nominal pore sizes larger than the diameter of the respective free virions.

Abstract
The objective of this article is to study the influence of exposure and socio-economic variables on the blood lead level of Malaysian school children. Data on respirable lead and blood lead of 346 school children were obtained from Kuala Lumpur (urban), Kemaman (semi-urban) and Setiu (rural). Respirable lead and blood lead were highest for Kuala Lumpur (95 ng/m3 and 5.26 micrograms/dL) followed by Kemaman (27 ng/m3 and 2.81 micrograms/dL) and Setiu (15 ng/m3 and 2.49 micrograms/dL), and the differences were statistically significant. The percentage of school children with excessive blood lead of 10 micrograms/dL or greater was 6.36% overall, and highest for Kuala Lumpur (11.73%). Regression analyses show that urban children are at higher risk of exhibiting excessive blood lead levels. Kuala Lumpur's school children have a 25 times greater risk of having excessive blood lead levels when compared to Kemaman's and Setiu's school children. Respirable and blood lead were correlated (r = 0.999, p = 0.021). Urban school children acquire higher blood lead levels than their rural and semi-urban counterparts, even after controlling for age, sex, parents' education and income levels. In conclusion, it is time that lead in the Malaysian environment and population be monitored closely, especially its temporal and spatial variability. Only then can a comprehensive preventive strategy be implemented.

Abstract
Systemic thickening of capillary endothelial basement membrane underlies the chronic complications of human diabetic microangiopathy. Since 99mTc-DTPA aerosol scintigraphy is a sensitive, non-invasive test of membrane permeability, we decided to study the effect of diabetes on the permeability of lung epithelium in diabetic patients using this test. Fifty (NIDDM) patients, aged 40-70 years, with or without complications, and who were non-smokers, were subjected to evaluation using 99mTc-DTPA aerosol. At the same time, pulmonary function tests, including carbon monoxide diffusion capacity, were done. Normal non-smoking subjects with no history of cardio-respiratory disease, who underwent 99mTc-DTPA and pulmonary function tests, served as controls. The risk factors which included age, sex, degree of control and presence of complications were noted. Twenty-nine (58%) of the patients had abnormal 99mTc-DTPA clearance. Thirty-four percent of the patients with complications and 24% of those without complications had abnormal clearance. Complications recorded included retinopathy, neuropathy and nephropathy. Fifty-five percent of patients with abnormal 99mTc-DTPA had suffered from diabetes for longer than 10 years. Sixty-two percent of patients with poor glycaemic control had abnormal 99mTc-DTPA. Diffusion capacity was not significantly affected in patients with complicated diabetes. Our preliminary results suggest that 99mTc-DTPA is a potentially sensitive test in assessing the degree of lung affection in diabetic patients. No significant correlation exists between diffusion capacity and 99mTc-DTPA. The risk factors did not affect the 99mTc-DTPA clearance, probably due to the small sample size.

Abstract
It is known that exercise induces modification in blood haemostasis. It is, however, not known whether alcohol consumption post-exercise influences these modifications during recovery. Eleven moderately active young men were studied immediately after a standardised cycle ergometer test and during the 24-hour period of recovery. Alcohol (0. 7 g/kg body mass) was given 1 hour after exercise on one test occasion, while an equal volume of alcohol-free solution was administered on the other. Exercise induced a significant increase in factor VIII activity with a significant shortening of activated partial thromboplastin time. Parallel increases in tissue plasminogen activity and antigen with a concomitant decrease in tissue plasminogen activator inhibitor-1 activity were also observed after exercise. During recovery, while the increase in factor VIII activity post-exercise persisted in both trials, fibrinolytic activity demonstrated a sharp fall. The elevated factor VIII activity was significantly higher at 5 and 22 hours during the alcohol trial compared with the control. Although no demonstrable effect of alcohol on tissue plasminogen activator activity was present from 1 hour after ingestion onward, tissue plasminogen activator antigen and tissue plasminogen activator inhibitor-1 antigen increased significantly 22 hours following alcohol ingestion. Further comparison between trials revealed a higher plasminogen activator inhibitor-1 activity 5 hours after alcohol ingestion. In conclusion, exercise-induced changes to blood haemostasis are balanced during exercise but not during recovery. Alcohol consumption after physical exercise further perturbs blood haemostasis and could constitute a thrombotic risk.

Abstract
Fifteen cases of unstable fracture-dislocation of the thoracolumbar spine have been treated by open reduction, short segment transpedicular fixation and fusion in Universiti Unit, Kuala Lumpur Hospital from January 1994 until December 1997. Twelve male and three female patients were injured; their age ranged from 18 to 45 years. Five fracture-dislocations occurred in the lower thoracic spine (T8 to T11), eight at the thoracolumbar junction (T12 to L2) and two in the lumbar spine (L3 to L5). All the patients had neurological deficit. Seven patients with incomplete or cauda equina lesions regained some neural function, while all eight with complete lesions remained unchanged. Ten of the fifteen cases were grossly unstable and translated beyond 50% of the width of the spinal column. At the time of follow up (more than one year in all patients), no loss of reduction or of fixation was noted in any patient. Solid fusion was achieved in all patients. The advantages of this method of treatment include stable fixation, with maintenance of sagittal and coronal spinal alignments, to allow early rehabilitation.
