Background: Epilepsy is a common disease but to achieve successful seizure control in developing countries is still a challenge. This study aimed to investigate the epilepsy services in Thailand. Methods: This was a survey by questionnaires on epilepsy service sent to 1,033 public hospitals all over Thailand. Results: The response rate was 54.1%. The results show that most of physicians that provide care for persons with epilepsy were General Practitioners (91.5%). Epileptologists and Neurologists accounted for only 11.1% and 14.4%. There were only 52 EEG, 54 CT Scan, and 6 MRI instruments in the entire country of 65 million. Standard antiepileptic drugs (AEDs) were widely available, phenobarbital (99.9%), phenytoin (96.0%), carbamazepine (97.9%), and valproic acid (89%) of institutions. The availability of new AEDs were: gabapentin (77.6%), topiramate (63.9%), levetiracetam (46.0%), lamotrigine (45.3%), pregabalin (33.6%), were also available in 77.6%, 63.9%, 46.0%, 45.3%, 33.6%, vigabatrin (14.5%), and oxcarbazepine (14.3%) of institutions. Intravenous AEDs used for status epilepticus patients include phenytoin (54.2%), phenobarbital (33.9%), and sodium valproate (12.1%). Therapeutic drug monitoring could be done in 45.7% of the responding hospitals. Conclusion: There is limited human and material resources for the care of epilepsy in Thailand. There is a need to develop a model of epilepsy care that is appropriate with the limited resources in the country. [ABSTRACT FROM AUTHOR]

Objective: To investigate the association of socioeconomic status (SES) (education, personal income, and occupation) with four major risk factors of stroke, those are diabetes, hypertension, hypercholesterolemia, and current smoker, Material and Method: The Thai Epidemiologic Stroke Study is a community-based cohort study, which recruitedparticipants from the general population from five geographic regions around the country. Cross-sectional baseline data of 19,997 (6,803 men and 13,194 women) participants, aged 45 to 80 years were included in the present analysis. Multiple logistic regression analysis was used to estimate association ofsocioeconomic indicators with the major risk factors of stroke., Results: SES was associated with a major risk factor of stroke. Among three indicators ofsocioeconomic status, education was more consistently associated with the risk factors than personal income and occupation, particularly in women. Education significantly inversely associated with diabetes (p = 0.015 in men and 0.002 in women, respectively), and current smoker in both sexes (p < 0.001), and with hypertension in women (p = 0.011). By contrast, education was significantly positively associated with hypercholesterolemia in women (p < 0.001)., Conclusion: The differences in the prevalence of the major risk factors of stroke between SES groups were important, and should be considered in the development ofpolicies or tailored strategies for prevention of stroke.

Objective: To determine the appropriate body mass index (BMI) and waist circumference (WC) cutoff point for identification of at least one cardiovascular risk factor (hypertension, dyslipidemia, and type 2 diabetes) in Thailand, and to compare the discrimination ability of BMI with that of WC for discrimination of at least one cardiovascular risk factor., Material and Method: Baseline health survey data of participants of Thai Epidemiologic Stroke (TES) Study, who were free from stroke, enrolled from five geographic regions around the country, were studied as cross-sectional analysis. Receiver operating characteristics curve (ROC) analysis was performed to determine the appropriate cutoff points of BMI and WC in identifying those with presence of at least one cardiovascular risk factors. The BMI or WC value with the shortest distance on the ROC curve was considered to be appropriate cutoffs. Comparing the ability of BMI in discrimination of at least one cardiovascular risk factor with that of WC was performed by comparing ROC area under curve (AUC)., Results: Among 19,621 (6,608 men and 13,013 women) participants with age range of 45 to 80 years, the average age was 59.8 years for men and 58.5 years for women. The appropriate cutoff point of BMI was 23 kg/m2 in men and 24 kg/m2 in women. The cutoffs of WC were 80 cm and 78 cm in men and women, respectively. In both gender, waist circumference (WC) (AUC in men = 0.684; 95% CI, 0.672-0.695, AUC in women = 0.673; 95% CI, 0.665-0.681) was significantly (p < 0.001) better than BMI (AUC in men = 0.667; 95% CI, 0.656-0.679, AUC in women = 0.636; 95% CI, 0.628-0.644) in discrimination of at least one cardiovascular risk factor., Conclusion: In Thai adults aged 45 to 80 years, the cutoff points of BMI should be 23 kg/m2 in men and 24 kg/m2 in women. For WC, 80 cm and 78 cm should be considered to be appropriate cutoffs for men and women, respectively. Waist circumference (WC) as a simple obesity index should be advocated for public health screening.

Objective: To assess stroke prevalence and stroke risk factors in Thailand., Material and Method: Thai Epidemiologic Stroke (TES) Study is an ongoing, community based cohort study that has been conducted in five geographic regions of Thailand. Baseline health status survey was started in 2004 and enrollment continued until the end of 2006. All participants who were suspicious of being stroke victims were verified. In this analysis, baseline data of 19,997 participants aged 45 to 80 years were identified and analyzed as a cross-sectional analysis., Results: Three hundred and seventy six subjects were proved to have a stroke thus resulting the crude prevalence of stroke to be 1.88% (95% CI, 1.69 to 2.07). Age standardization to Segi world standard population was 1.81% (95% CI, 1.62 to 1.99). Crude prevalence among adults aged > or = 65 years was 2.70% (95% CI, 2.28 to 3.11). Stroke prevalence differed among five geographic regions of the country (Bangkok 3.34%, Central region 2.41%, Southern 2.29%, Northern 1.46% and Northeastern 1.09%). Using multiple logistic regression analysis, factors associated with higher stroke prevalence were male gender (p < 0.001), occupational class (p < 0.001), geographic region (p < 0.001), hypertension (p < 0.001), diabetes mellitus (p = 0.002) and hypercholesterolemia (p = 0.026)., Conclusion: Stroke prevalence in Thailand from TES study is higher than previous studies, but it is lower than developed countries, probably due to high case fatality rate in Thai population. Geographic variation in stroke prevalence is found more in Bangkok, Central and Southern regions. Longitudinal follow-up of TES cohort study will provide further information on risk factors and incidence of stroke.

Background and Objective: Prognosis of cerebral venous sinus thrombosis (CVST) has never been studied in Thailand. A simple prognostic score to predict poor prognosis of CVST has also never been reported. The authors are aiming to establish a simple and reliable prognostic score for this condition., Material and Method: The medical records of CVST patients from eight neurological training centers in Thailand who received between April 1993 and September 2005 were reviewed as part of this retrospective study. Clinical features included headache, seizure, stroke risk factors, Glasgow coma scale (GCS), blood pressure on arrival, papilledema, hemiparesis, meningeal irritation sign, location of occluded venous sinuses, hemorrhagic infarction, cerebrospinal fluid opening pressure, treatment options, length of stay, and other complications were analyzed to determine the outcome using modified Rankin scale (mRS). Poor prognosis (defined as mRS of 3-6) was determined on the discharge date., Results: One hundred ninety four patients' records, 127 females (65.5%) and mean age of 36.6 +/- 14.4 years, were analyzed Fifty-one patients (26.3%) were in the poor outcome group (mRS 3-6). Overall mortality was 8.4%. Univariate analysis and then multivariate analysis using SPSS version 11.5 revealed only four statistically significant predictors influencing outcome of CVST They were underlying malignancy, low GCS, presence of hemorrhagic infarction (for poor outcome), and involvement of lateral sinus (for good outcome). Thai venous stroke prognostic score (TV-SPSS) was derived from these four factors using a multiple logistic model., Conclusion: A simple and pragmatic prognostic score for CVST outcome has been developed with high sensitivity (93%), yet low specificity (33%). The next study should focus on the validation of this score in other prospective populations.

Objective: To study the effect on quality of life (QOL) of a seizure attack while driving in persons with epilepsy (PWE)., Methods: From four provincial and eight university hospitals in Thailand, we enrolled epileptic patients who drove a car or motorcycle or used to drive. The SF-36 questionnaire was used to evaluate QOL. The mean SF-36 score for all dimensions was calculated and compared with patients who either had or did not have a seizure attack while driving and in those who either had or had not been involved in a traffic accident while driving., Results: We had 245 adult PWE who drove a car or motorcycle or used to drive. Of these, 69 cases (28%) had a seizure attack whilst driving. Over half (36/69; 57%) had had seizure-related accidents, most of which were mild but about 20% needed hospitalization. PWE having a seizure attack while driving had a significantly lower QOL in four of the eight categories compared with patients who had not. PWE who had a seizure-related accident had a significantly lower mean value in the vitality category than those who did not., Conclusions: Seizure attacks while driving diminished QOL in PWE even though they only suffered minor injuries. Driving as a QOL issue should be discussed with patients. A good public transportation system would ease the need to drive.

Background: Since its first clinical use more than 30 years ago, Valproic acid is still being widely prescribed It has been available in Thailand for more than 20 years. Sodium valproate slow-released (SVSR) form has been used in clinical practice in Thailand since 1990. The objectives of this open study were to access the compliance and satisfaction consequences in the epileptic patients., Material and Method: In this prospective, multi-center study, the authors compared the compliance and satisfaction consequences in epileptic patients switched from more than two times daily sodium valproate enteric-coated tablet (SVEC) regimen to the same total daily dose of SVSR form given once or twice daily., Results: Eighty-nine of the 100 patients completed the study. 43.8% were male (39 of 89 patients). Mean age was 34.74 +/- 12.67 years. Most common etiology of epilepsy was idiopathic 40.4%. Patients were very/fairly happy with the SVSR form 94.4% compared to the SVEC form 56.2% (p = 0.000). Patients had been experiencing no problem with the SVSR form 67.4% compared to SVEC form 38.2% (p = 0.000) and also never missing taking SVSR. form 77.5% compared to SVEC form 40.4% (p = 0.000). According to convenience, patients preferred to administer SVSR form once a day 92.1% and never over taking dosed the antiepileptic drug 96.6%. SVSR form had fewer side effects than the enteric-coated form interms of memory problem (40.4% vs 48.3%) (p = 0.000), sleepiness (30.3% vs 42.7%) (p = 0.041) and difficulty in thinking clearly (38.2% vs 44.9%) (p = 0.001). The patients were seizure free during the study period comparing SVSR form 76.4% to SVEC form 65.2% (p = 0.011)., Conclusion: Patients preferred once daily regime. Switching from SVEC to SVSR form increased seizure free, reduced side effects, improved patient's compliance and satisfaction.
