To establish the correlation between pre-pregnancy body mass index (BMI) and pregnancy outcomes in Thai women. Cultural modernization has changed lifestyle of Thai population including eating habits, leading to higher incidence of overweight in pregnant woman. This study aims to analyze the relationship between BMI of Thai women before pregnant and pregnancy outcomes. The study population included 3,715 deliveries in Rajavithi Hospital, Bangkok, Thailand, between January 1, 2009 and December 31, 2009. The number of individuals in each adverse outcomes was compared with those in each BMI group. Odds ratios were calculated using normal BMI as reference. The overweight and obese BMIs resulted in significant risk of cesarean section, pre-eclampsia and diabetes mellitus with [OR (95% CI)] 1.37 (1.13-1.68), 2.3 (1.4-3.7), 4.02 (2.66-6.08) for overweight and 2.11 (1.53-2.90), 5.7 (3.3-9.8), 6.02 (3.52-10.32) for obesity, respectively. The underweight BMI resulted in significant risk of preterm, very preterm, low birthweight (LBW) infant with [OR (95% CI)] 1.79 (1.48-2.16), 1.69 (1.15-2.47), 1.61 (1.27-2.03). Only obesity attributed to significant risk of macrosomia with [OR (95% CI)] 5.36 (2.73-10.52). Both overweight and obesity led to significant risk of postpartum hemorrhage and severe postpartum hemorrhage with [OR (95% CI)] 1.71 (1.21-2.44), 2.13 (1.08-4.22). No correlation was found between pre-pregnancy to stillbirth and congenital anomaly. Overweight and obesity could increase risk in cesarean section, pre-eclampsia, DM, PPH and severe PPH, but were protective factors of LBW. Only obesity played high risk of macrosomia. Underweight was a protective factor for cesarean section, pre-eclampsia, DM and PPH, but could cause risk in preterm, very preterm and LBW.

Stevens-Johnson syndrome (SJS) is a rare and severe life-threatening hypersensitivity syndrome. The etiology is unclear but is associated with drug exposure or infections and frequently high morbidity and mortality. To determine etiologies, treatments and complications of Stevens-Johnson syndrome (SJS) in children. A retrospective descriptive study was performed at Queen Sirikit National Institute of Child Health during 1979 and 2007 (29-year study). The authors collected and separated data into three phases from 1979 to 1987, 1988 to 1997 and 1998 to 2007. Diagnosis was confirmed by pediatric dermatologists. There were 189 patients, 56 cases between 1979-1987, 72 cases between 1988-1997 and 61 cases between 1998-2007. The ratio of male to female was 1.6: 1. The range of age was from 2 months to 15 years old with a mean age of 5.5 years. One hundred and sixty-five cases (87%) had a history of drug taking before onset of the rash. The most common drugs exposure were antibiotics in 69 cases (42%), anticonvulsant drugs in 58 cases (35%), non-steroids anti-inflammatory drugs in 8 cases (5%), antimalarial drugs in 4 cases (2%) and unknown drugs in 26 cases (16%). Mycoplasma infections were found in 5 cases (3%). One hundred and nine cases (58%) were treated with systemic corticosteroids. The corticosteroid treatment was increasing from 18% in the first phase to 64% and 87% in the second and third phase respectively. The overall complications were found in 38 cases (20%) included bacterial skin infections in 16 cases (8%), eye complications in 12 cases (6%), hepatitis in 4 cases (2%) and other complications in 6 cases (2%). Ten patients (5%) died from sepsis and underlying diseases. The mortality rate declined from 9% in the first phase to 1.5% in the third phase. Etiology of SJS in children was associated with drug exposure with the most commonly implicated drug being antibiotics and anticonvulsants. Corticosteroid may have a role in the treatment of SJS.

There has been confusion regarding the clinical classification of dengue. The current WHO classification used since the 70s classifies dengue into dengue fever (DF), dengue hemorrhagic fever (DHF), dengue shock syndrome (DSS). In 2009, a new classification of dengue proposed by WHO Tropical Disease Research (TDR) was published in the WHO TDR 2009 dengue guidelines. This new classification classifies dengue into dengue (D), dengue with warning signs (DW) and severe dengue (SD). To compare the effectiveness in clinical management between the current WHO classification and the newly suggested classification (TDR) and to assess the 4 criteria of the DHF case definition of the current WHO classification for possible modification. A prospective study of suspected dengue patients admitted to the Dengue Unit, Queen Sirikit National Institute of Child Health between June-August 2009 was done. All cases were managed according to the Thai National Dengue Guidelines 2008. The final diagnoses were based on the current WHO Classification together with dengue laboratory confirmation. TDR classification was applied later by the author, using the data from the present study case report forms of each patient. Statistical analysis comparing clinical and laboratory data between each group of patients was done by using SPSS version 14. Total 274 confirmed dengue patients and 24 non-dengue febrile illnesses (ND) were used for analysis. There were 180 DF (65.7%), 53 DHF grade I (19.3%), 19 DHF grade II (6.9%), 19 DHF grade II (6.9%) and 3 DHF grade IV (1.1%) as classified by the current WHO classification while the suggested TDR classified 85 (31%), 160 (58.4%) and 29 (1.1%) as D, DW and SD respectively. At least one of the warning signs were found in 50, 53.3, 83, 88.2, 100 and 100% of ND, DF, DHF grade I, DHF grade II, DHF grade III and DHF grade IV patients. Vomiting and abdominal pain were the 2 most common warning signs found in both ND and dengue patients. Intensive monitoring and careful medical and i.v. fluid management were needed for 94 DHF patients compared to 189 DW and SD patients by the new TDR classification. There were 8 DSS patients who had AST > 1,000U and one patient presented with encephalopathy. These 8 patients cannot be classified properly in the current WHO classification. One non-dengue patient who presented with gastrointestinal bleeding was classified as SD. Bleeding and/or positive tourniquet test was found in and 69.7% of DHF patients. Plasma leakage detected using hemoconcentration, chest x-ray (CXR) and ultrasonography. Hemoconcentration could detect plasma leakage in 44.7% and CXR added up evidence of plasma leakage to 86.3%. Ultrasonography was the most sensitive technique to add evidence of plasma leakage up to 100%. Platelet < or = 100,000 cells/mm3 was found in 93.5% of DHF patients. Current WHO classification is recommended for continuing use because the newly suggested TDR classification creates about 2 times the workload to health care personnel. In addition, the TDR classification needs dengue confirmatory tests. More than 90% of DHF defined by WHO case definition are dengue confirmed. However, current WHO classification needs to be modified for more simple and friendly use. The suggested modification is to address plasma leakage as the major criteria. Tourniquet test positive or bleeding symptoms can be considered as minor criteria. Unusual dengue is proposed to be added to the current WHO classification to cover those patients who do not fit with the current WHO classification.

Children may suffer from post-traumatic stress disorder after disaster. There was a severe tsunami following an undersea earthquake off the Sumatra coast of Indonesia. There were 20,000 children in 6 southwestern provinces of Thailand who were possibly affected. To study the prevalence of post-traumatic stress disorder (PTSD) in Thai students in the area affected by the December 26th, 2004 tsunami disaster, Thailand. One thousand six hundred and fifteen surviving students from two schools in Takua Pa district located in Phang-nga Province, Thailand participated in this longitudinal study. Screening was done by using Pediatric Symptom Checklists part II (PSC-II), Childhood Depressive Intervention (CDI) and the Revised Child Impact of Events Scales (CRIES 8). PTSD was diagnosed by child and adolescent psychiatrists by using criteria of DSM-IV. The intervention included psychological first aid, psycho-education, cognitive-behavioral therapy, medication in severe cases, group support for students, parents and teachers which was done, beginning at 10 days after the tsunami disaster. Data were analyzed by using SPSS version 12.0. The prevalence rates of PTSD in the students facing the tsunami disaster in the study group were 573, 46.1, 31.6, 7.6, 4.5, 3.9 and 2.7% at 6 weeks, 6 months, 1 year, 2 years, 3 years, 4 years and 5 years after the disaster, respectively. Female to male ratio was 1.7: 1. The peak age was 9-10 years old. The top five on the list of symptoms in PTSD were distress with cue, intrusive thought, functioning impairment, startled response, terrified and hyper vigilance. Seven cases (3.1%) were diagnosed partial PTSD, still exhibited a wide range of PTSD symptoms but did not fulfill the DSM-IV diagnostic criteria. The top five on the list of symptoms in partial PTSD were avoiding thought/feelings, terrified, avoiding place/activities, distress with cue and startled response. The prevalence of PTSD among tsunami victims was 57.3% at 6 weeks after the disaster. It declined sharply at 2 years after the event. Despite receiving financial, rehabilitation and mental health support, 2.7% of the victims continued to suffer from PTSD 5 years after the disaster.

Background Herbal and dietary supplements are commonly used throughout the World. There is a tendency for underreporting their ingestion by patients and the magnitude of their use is underrecognised by Physicians. Herbal hepatotoxicity is not uncommonly encountered, but the precise incidence and manifestations have not been well characterised. Aims To review the epidemiology, presentation and diagnosis of herbal hepatotoxicity. This review will mainly discuss single ingredients and complex mixtures of herbs marketed under a single label. Methods A Medline search was undertaken to identify relevant literature using search terms including 'herbal', 'herbs', 'dietary supplement', 'liver injury', 'hepatitis' and 'hepatotoxicity'. Furthermore, we scanned the reference lists of the primary and review articles to identify publications not retrieved by electronic searches. Results The incidence rates of herbal hepatotoxicity are largely unknown. The clinical presentation and severity can be highly variable, ranging from mild hepatitis to acute hepatic failure requiring transplantation. Scoring systems for the causality assessment of drug-induced liver injury may be helpful, but have not been validated for herbal hepatotoxicity. Hepatotoxicity features of commonly used herbal products, such as Ayurvedic and Chinese herbs, black cohosh, chaparral, germander, greater celandine, green tea, Herbalife, Hydroxycut, kava, pennyroyal, pyrrolizidine alkaloids, skullcap, and usnic acid, have been individually reviewed. Furthermore, clinically significant herb-drug interactions are also discussed. Conclusions A number of herbal medicinal products are associated with a spectrum of hepatotoxicity events. Advances in the understanding of the pathogenesis and the risks involved are needed to improve herbal medicine safety. © 2012 Blackwell Publishing Ltd.

Dengue virus infection is an important mosquito-borne disease with the reported 40,000-100,000 cases per year in Thailand. Shock is one of the common presentations at the emergency room (ER) and dengue shock syndrome (DSS) is among the common causes of shock. Proper and timely management of DSS determines the outcomes and prognosis of DSS patients. To find the prevalence of DSS at the ER and evaluate the medical management and risk factors associated with the outcome of DSS patients. A retrospective study on patients who presented with shock, including DSS patients at the ER of Queen Sirikit National Institute of Child Health (QSNICH), Bangkok, Thailand, from 1st January 2008 to 31st December 2009 was done. The prevalence of patients who presented with shock at the ER was retrieved from the Statistical and Information Technology Departments. Out-patient cards and In-patient charts of DSS patients were reviewed. Clinical and laboratory data were compared between recovered and death cases. Statistical analysis was done by using SPSS version 14.0. There were 109 shock patients seen at the ER during the present study period with 59 DSS (54.1%), 30 septic shock (27.5%), 13 hypovolemic shock (11.9%), 1 cardiogenic shock (0.9%) and 6 other non-specific shock (5.5%). DSS cases were found all year round with the peak prevalence from June to August which is the rainy season. Twenty-six of DSS (44.1%) were referred cases and 5 of them died, case fatality rate was 8.8%. All death cases had prolonged shock, massive bleeding and liver failure at presentation while these findings were found in 2 (4.4%), 16 (35.6%) and 10 (22.2%) cases of recovered cases. Encephalopathy, renal failure and respiratory failure were found in 80, 60 and 60% of the death cases while in recovered cases they were found in 11.1, 4.4 and 2.2%. Acidosis was found higher in the death group (60%) than in recovered group (8.9%). Other common presenting findings in death and recovered groups were bleeding (35.6 vs 100.0%), fluid over load (31.1 vs. 80%), hyponatremia (40% for both groups) and hypocalcemia (83.3 vs. 80%). Among the 45 recovered cases; 3 cases were misdiagnosed and another 8 cases (17.8%) received no i.v. fluid at the ER. Cross matching was done in 32 cases (64%) and blood was transfused in 16 cases (50% of the cross matching). DSS is the most common shock found at the ER especially during June to August. ER physicians should be alert for making the correct diagnosis of DSS with proper intravenous fluid resuscitation and correction of the common complications/laboratory abnormalities, i.e. acidosis, hyponatremia, hypocalcemia and cross matching for massive bleeding. A referred case with liver failure together with renal and respiratory failure was likely associated with mortality while fluid overload and significant bleeding do not if they are managed properly. Early signs of shock should be detected in walk in cases to prevent later shock after admission.

Nicotine increases serotonin release in the brain. Gene polymorphisms in the serotonergic system have been suggested to be associated with smoking behavior. We investigated a possible association between two polymorphisms in the serotonergic system - HTTLPR of a serotonin transporter gene and 5-HT(2A) at position T102C - with biochemical and anthropometric parameters, and with cigarette smoking in an investigation of 200 smokers and 111 non-smokers. The two polymorphisms, HTTLPR and 5-HT(2A) at position T102C, were genotyped by PCR-RFLP. They were not significantly associated with smoking status in these Thai males. Among the smokers, thiocyanate concentrations and quantity of cigarettes smoked (cigarette pack-years) were significantly higher for individuals with LL/LS genotypes than SS genotypes of 5-HTTLPR (all P < 0.05), whereas "age at starting smoking" and "duration of smoking" were not significantly different between these two genotypes. Moreover, anthropometric variables, comprising triceps skinfold thickness, arm circumference, waist circumference, hip circumference, and waist-to-hip ratio, were significantly higher for the CC/TC genotypes of 5-HT(2A) than the TT genotype (all P < 0.05), except for body mass index. HTTLPR and 5-HT(2A) T102C polymorphisms were not significantly associated with smoking status among Thai males; however, the HTTLPR polymorphism among smokers appears to be an indicator of increased smoking intensity consisting of cigarette pack-years and thiocyanate concentrations. The 5-HT(2A) T102C polymorphism plays a role in the anthropometric profiles, triceps skinfold thickness, arm circumference, waist circumference, hip circumference, and waist-to-hip ratio, but not smoking status in Thai subjects.

The authors aimed to evaluate the safety and immunogenicity of a live attenuated SA14-14-2 Japanese Encephalitis (JE) vaccine in healthy Thai infants. One hundred and fifty subjects aged 9-15 months were vaccinated with one dose of this vaccine. Regarding the vaccine safety, during the 28-day post-vaccination follow-up, no vaccine-related serious adverse events were reported. In terms of immunogenicity, the sero-conversion rate of a single dose vaccination was 95% (95% CI, 90.0-97.6%) within 90 days after vaccination and the geometric mean titer (GMT) was 66.1. Eight subjects with JE seronegative on days 28-35 post-vaccination became sero-positive on day 90. Seven subjects who remained sero-negative during days 28-35 and day 90 post-vaccination were successfully sero-converted after receiving a second dose 3 months later. Thus, two doses of this JE vaccine resulted in a 100% (95% CI, 97.3-100%) sero-conversion rate with the GMT of 260.8. Eight children with GMTs lower than protective level after a single vaccination demonstrated a booster response with GMT of 1237 after the second dose of JE vaccination. In conclusion, the live attenuated SA14-14-2 vaccine was safe, well tolerated and highly immunogenic with 95% and 100% sero-conversion rate after one and two doses, respectively. Nevertheless, its long-term immune response and possible influences from natural dengue infection requires further evaluation.

Diffraction of normal compression waves by a penny-shaped crack in a fluid-saturated porous medium is investigated. Two wave types are considered, namely, compressional wave of the first kind, and the second kind. The former, also known as fast wave, propagates primarily through the solid, whereas the latter or slow wave, propagates mainly in the fluid. Each wave propagates in the medium along with induced wave of the same type in the companion constituent of the material. Application of Biot's theory in conjunction with integral transform technique reduces the problem to a mixed boundary-value problem whose solution is in turn governed by a Fredholm integral equation of the second kind. Near-field and far-field solutions are obtained in terms of the dynamic stress-intensity factor and the scattering cross section, respectively. They are of particular importance to the linear elastic fracture mechanics (LEFM) and in the scattering theory of elastic waves. The mode I stress-intensity factors are computed numerically for a set of selected material property values, and shown graphically for various mass density and viscosity-to-permeability ratios. The obtained results reveal significant impact of the presence of pore fluid upon the stress-intensity factors, both magnitudes and frequencies at their peak values. The influence of the fluid is also observed from the calculated scattering cross sections of the scattered far-field. Accuracy of the present solution procedure is verified by comparing the numerical results with existing results in the limiting case of dry elastic materials. © 2013 Elsevier Ltd.

An application of the Biot's theory to the diffraction problem of plane harmonic dilatational waves (P-waves) of the first kind and the second kind by a line crack or geometric discontinuity of finite width embedded in a saturated two-phase medium is presented in this paper. The crack surfaces are assumed impermeable, and the integral transform method is utilized to reduce the mixed boundary-value problem to a single Fredholm integral equation. The magnitudes of the intensity of the stress fields near the crack tips measured by Mode I dynamic stress-intensity factor (dimensionless) are computed and displayed graphically against dimensionless circular frequency (ω) for several dimensionless material property values, namely, viscosity-to-permeability and mass density ratios. In the case of the normally incident P-waves of the first kind, the results in terms of stress-intensity factor are also compared with the corresponding values of dry elastic material. All the stress-intensity factor curves are shown to exhibit a similar character in that they rise to the peaks at certain frequency values and then decay with increasing frequencies. At certain frequency ranges and material property values, amplification in the dynamic stress-intensity factor can be substantially larger than those encountered in dry elastic materials. The stress-intensity factor is found to be more affected by the changes in the ratio of viscosity-to-permeability at lower mass density ratio. With fluid mass density 10% of the bulk mass density, the viscosity-to-permeability ratio of 0.01 gives the highest increase of about 32% in the magnitude of stress-intensity factor compared to the dry material counterpart value, while a decrease of about 9% is observed for the viscosity-to-permeability ratio of 100. It is also found that change in mass density ratio has significant effect upon the magnitude of stress-intensity factor at lower ratio of viscosity-to-permeability. As for the normally incident P-waves of the second kind, the presence of the pore fluid affects both the magnitude and character of the stress-intensity factor. Large variations in the magnitude of stress-intensity factor are observed as viscosity-to-permeability ratio changes from 1 to 100. At the ratio of viscosity-to-permeability of 1.0, the stress-intensity factor curves increase gradually with frequency and exhibit the peaks in curves for mass density ratio of 0.3 and higher. As the viscosity-to-permeability ratio is raised to 100, the stress-intensity factor curves increase monotonically with frequency at a much faster rate throughout the frequency range of interest (ω = 0-2), and the change in mass density ratio is shown to have little effect on the stress-intensity factor, especially within the low frequency ranges. The results obtained in this study are useful in the mechanics of fracture initiation of saturated porous materials under the fluctuating mechanical and/or pore fluid loadings that are periodic with time. © 2012 Elsevier Ltd.
