The effects of COVID-19 measures on the hospitalization of patients with epilepsy and status epilepticus in Thailand: An interrupted time series analysis. Epilepsia Open 2022; 7:325-331. [PMID: 35403839 PMCID: PMC9110909 DOI: 10.1002/epi4.12600] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2022] [Revised: 03/13/2022] [Accepted: 04/08/2022] [Indexed: 12/04/2022] Open
Abstract
Objective To investigate the effect of Coronavirus disease 2019 (COVID‐19) measures on the hospitalization of patients with epilepsy and status epilepticus (SE). Methods This interrupted time series design included data from the Thai Universal Coverage Scheme electronic database between January 2017 and September 2020. The monthly hospitalization rate of epilepsy and SE was calculated by the number of hospitalizations divided by the midyear population. Segmented regression fitted by ordinary least squares (OLS) was used to detect the immediate and overtime effects of COVID‐19 measures on the hospitalization rate. Results During January 2017 and September 2020, the numbers of epilepsy and SE patients admitted to the hospital were 129 402 and 15 547 episodes, respectively. The monthly trend of the hospitalization rate in epilepsy decreased immediately after the COVID‐19 measure (0.739 per 100 000 population [95% CI: 0.219 to 1.260]). In particular, the number of children declined to 1.178 per 100 000 population, and the number of elderly individuals dropped to 0.467 per 100 000 population, while there was a nonstatistically significant change in SE. Significance COVID‐19 measures reduced the hospital rate in epilepsy, particularly in children and adults. However, there was no change in SE patients.

Abstract
BACKGROUND: Epilepsy is a common neurological disease. Treatment with original antiepileptic drugs may result in high cost. Levetiracetam (LEV) is a broad-spectrum antiepileptic drug. Several studies showed that generic LEV is safe, effective, and saves cost. There are limited data on predictors of seizure control in persons with epilepsy treated with LEV, particularly switch therapy to generic LEV.
METHODS: This study was a comparison study conducted at two tertiary care hospitals. One hospital used an original LEV, while another one switched to generic LEV. The outcomes of the study included seizure control after switching to generic LEV treatment, treatment cost, dosage of LEV, adverse events of LEV, switching therapy to original LEV, emergency room visit, and abnormal laboratory tests. These outcomes were compared between the generic and original LEV. Seizure control defined by free of seizure after switch therapy. Predictors of seizure control were analyzed by multiple logistic regression analysis.
RESULTS: During the study period, there were 96 eligible patients and treated with generic LEV in 61 patients (63.54%). Regarding treatment outcomes, the generic LEV group had significantly higher proportions of seizure control (91.80% vs. 45.71%) than the original LEV group. The original LEV group had significantly higher cost than the generic LEV group (65,250 vs. 9500 Baht; p < 0.001). The final model had two factors remaining: Generic LEV and frequency of seizure before switch therapy. Generic LEV was independently associated with seizure control with adjusted OR of 6.35 (95% CI of 1.73, 23.34).
CONCLUSION: Switch therapy to generic LEV is an alternative therapy with comparable efficacy, lower cost, and safe. Generic LEV and frequency of seizure attack before switch therapy to generic LEV may be related to seizure control.

The Efficacy and Safety Profile of Generic Intravenous Levetiracetam in a Real-World Setting. Curr Ther Res Clin Exp 2021; 95:100648. [PMID: 34840633 PMCID: PMC8605403 DOI: 10.1016/j.curtheres.2021.100648] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2021] [Accepted: 10/10/2021] [Indexed: 11/27/2022] Open
Abstract
Background There are 3 main epileptic conditions in hospital settings that may require intravenous antiepileptic treatment: status epilepticus, acute repetitive convulsive seizures, and postoperative seizures. Generic intravenous levetiracetam (IV LEV) (Focale; Great Eastern Drug Co, Bangkok, Thailand), has been reported to have comparable efficacy to original IV LEV for treating status epilepticus and acute repetitive convulsive seizures in a randomized controlled trial. At present, there are limited data on the efficacy and tolerability of generic intravenous LEV in real-world situations. Objective This study aimed to evaluate the clinical outcomes of generic IV LEV in a real-world setting. Methods A retrospective study and analyses were conducted. All adult patients who used IV LEV at University Hospital, Khon Kaen University, Thailand from June 1, 2019, until February 15, 2020, were included. Data were analyzed and reported in terms of the efficacy and tolerability of generic IV LEV. Results Ninety-three patients received IV LEV by 3 indications: status epilepticus, acute repetitive convulsive seizures, and postoperative seizures. The proportions of these 3 indications were 41.94% (39 patients), 9.67% (9 patients), and 48.39% (45 patients), respectively. The average seizure control rate at 24 hours was 89.25%. The seizure control rate was significantly higher in the acute repetitive convulsive seizures and postoperative seizure groups than in the status epilepticus group when generic IV LEV was given as the first-line treatment (75.00%; 88.37% vs 50.00%; P 0.035). The average length of hospital stay was 18.24 (25.40) days. There was no significant discharge status among the 3 groups (P = 0.348). Moreover, the average mortality rate was 5.38%. Side effects were reported in 14 patients (15.05%). The 2 most common side effects were vomiting and bronchospasm (3 patients; 3.22%). There were 10 patients with uncontrolled seizures at 24 hours (10.75%). The only factor associated with uncontrolled seizures at 24 hours was a history of epilepsy. The uncontrolled seizure group had a higher proportion of epilepsy patients than the seizure-controlled group (70.00% vs 33.73%; P = 0.037). Poor discharge status (not improved/death) was 18.28% (17 patients). There was no significant factor between those with an improved or poor discharge status. Conclusions Generic IV LEV was effective and relatively well tolerated in the 3 clinical settings (ie, status epilepticus, acute repetitive convulsive seizures, and postoperative seizures). Further clinical data are still required to confirm the results of this study. (Curr Ther Res Clin Exp. 2022; 83:XXX–XXX)

Abstract
INTRODUCTION Intravenous levetiracetam (IV LEV) is approved for treatment status epilepticus (SE). However, the drug's high cost must be considered when deciding on a treatment strategy. This study aimed to compare the efficacy of brand-name and generic IV LEV for acute repetitive convulsive seizure (ARCS) or SE. METHODS Forty patients aged 18 years or older who had been diagnosed with SE or ARCS were included in this double-blind study. Patients were randomly assigned at a 1:1 ratio (via computer-generated code) to receive either brand-name or generic IV LEV. The primary outcomes were seizure control and the number of seizure exacerbations during the 24 h after drug administration, while the secondary outcomes were electroencephalographic (EEG) findings, serious adverse events, and clinical outcome at hospital discharge. RESULTS Forty patients were randomly assigned administration with either brand-name IV LEV (10 SE and 10 ARCS patients) or generic IV LEV; 7 SE and 13 ARCS patients). There was no significant difference in patients' baseline characteristics. The seizure control rate was 75% in the brand-name IV LEV group and 65% in the generic IV LEV group (p value: 0.490). Five (25%) patients in the brand-name IV LEV group, and six (30%) patients in the generic IV LEV group developed seizure exacerbations within 24 h after drug administration (p value 0.723). There were no reports of drug-related adverse events. Two of the patients taking brand-name IV LEV and one taking the generic IV LEV died (p value > 0.999). CONCLUSION Treatment with the generic IV LEV had comparable outcomes with brand-name IV LEV. The generic IV LEV may be an alternative medication for the treatment of SE and ARCS to reduce treatment costs. TRIAL REGISTRATION TCTR20190513001. FUNDING Great Eastern Drug Company.

Abstract
Epileptic seizures are refractory to treatment in approximately one-third of patients despite the recent introduction of many newer antiepileptic drugs (AEDs). Development of novel AEDs therefore remains a high priority. Perampanel is a first-in-class non-competitive selective AMPA receptor antagonist with a unique mechanism of action. Clinical efficacy and safety of perampanel as adjunctive treatment for focal seizures with/without secondary generalization (±SG) and primary generalized tonic-clonic (PGTC) seizures have been established in five phase 3 randomized controlled trials (RCTs), and a long-term extension study, and perampanel is approved as monotherapy for focal seizures ±SG in the USA. In patients with focal seizures ±SG, add-on perampanel resulted in median percent reduction in seizure frequency 23.3%-34.5% and ≥50% responder rate 28.5%-37.6%; in PGTC seizures, these results were 76.5% and 64.2%, respectively. Efficacy among adolescents (reduction in seizure frequency 34.8%-35.6%; ≥50% responder rate 40.9%-45.0%) and elderly people (reduction in seizure frequency 12.5%-16.9%; ≥50% responder rate 22.2%-42.9%) is similar to those in adults, and results remain comparable between Asian (reduction in seizure frequency 17.3%-38.0%) and global populations. Perampanel has been extensively studied in real-world clinical practice, with similar efficacy and safety results to the RCTs (≥50% responder rate 12.8%-75.0%; adverse events of somnolence/sedation, dizziness, ataxia, and behavioral changes). Real-world observational studies suggest that perampanel tolerability can be improved by slow titration (2 mg every 2-4 weeks), and bedtime administration can mitigate somnolence and dizziness. Counseling about the potential for behavioral changes and close monitoring are recommended.

Abstract
Epilepsy is a common public health problem and needs multi-disciplinary treatment. Therapeutic drug monitoring (TDM) is one of step of the multi-disciplinary treatment in epilepsy at Epilepsy clinic, Khon Kaen University (Thailand). The TDM service has been established since 2008. Here, we aimed to study the roles of TDM order and epilepsy control. This is a prospective descriptive study in which data collection was done from January 1 to December 31, 2010, the period when pharmacists took part in assessing the appropriateness in measurement and interpretation of TDM in order to provide suggestions for physicians. The 112 patients under study had an average age of 38.21±15.36 years; 254 samples were collected for therapeutic drug monitoring; phenytoin was submitted mostly for drug monitoring at 46.46%; 44.49% of submissions for drug level monitoring were made owing to a suspected sub-therapeutic level. Associations were found between reasons of sending samples for drug level monitoring and the measured drug levels, i.e., 66.67% of drug levels found was so low that they were undetectable in sample for patients' compliance investigation and 38.94% of the drug levels were found to be sub-therapeutic as for the case where submission of samples was done because of suspected sub-therapeutic level, 40% of the cases were found to be in toxicity range in the cases with suspected over-therapeutic levels and monitoring levels, 58.25% were found to be within the therapeutic range. Pharmacists used the interpreted results in patients' care by recommending physicians to monitor therapeutic drug closely, to adjust the dosage of drugs, and to recommend checking patients' compliance in their use of drugs at 56.5, 38.9, and 4.3%, respectively. Physicians' responses were found to be absolute follow, partial follow and not follow at 77.95, 11.03, and 7.48%, respectively. In conclusion, associations were found between reasons of TDM order and measured drug level. Therapeutic drug monitoring services at the Epilepsy Clinic was useful in supporting clinical information queries. Pharmacists could make use of interpreted drug level information by recommending physicians to monitor drug levels and adjust individual dosage regimen accordingly. It should be noted that physicians accepted pharmacists' recommendation, denoting multi-disciplinary care team that would lead to greater efficiency.

Abstract
Patients with prosthetic heart valves require lifelong anticoagulation to prevent thromboembolism. When they have intracranial haemorrhage, anticoagulation has to be withheld. This study was aimed to identify safety duration and complications of anticoagulation withholding in patients with prosthetic heart valves and intracranial haemorrhage. This was a retrospective descriptive study in 26 prosthetic heart valve patients hospitalised in Srinagarind Hospital, Khon Kaen University because of intracranial haemorrhage from 2003 to 2008. Range of anticoagulation withholding was 1 to 26 days with mean 8.5 ± 7.7 days. Most patients (84.6%) were withheld anticoagulation for less than 14 days. There were five in-hospital deaths mostly within 3 days of admission from severe intracranial haemorrhage. No data of reintroduction of anticoagulation was found in three patients because they were lost to follow up. One patient had right basal ganglia infarction after 7 days of anticoagulation withholding. Prosthetic heart valve dysfunction was suspected in one patient who withheld anticoagulant for 76 days. Discontinuation of anticoagulation in patients with prosthetic heart valves and intracranial haemorrhage for less than 7 days was associated with low thromboembolic risk and there was no clinical evidence of prosthetic heart valve dysfunction when anticoagulation was withheld for less than 14 days.

Abstract
BACKGROUND Status epilepticus (SE) is a neurological emergency condition. Intravenous phenobarbital (PB) is recommended for refractory SE treatment. However, intravenous PB is unavailable in Thailand. Enteral PB has been shown to be effective in SE children. METHODS In adult SE patients, the efficacy of enteral PB as an adjunctive therapy has been reported. This is a case series of adult SE patients who were treated with enteral PB at Khon Kaen University Hospital, Thailand. The clinical features and clinical outcomes are reported. RESULTS There were six patients; five patients had convulsive SE, and one patient had nonconvulsive SE. All patients received PB enterally, at dosages of 900 mg initially and repeated doses of 900 mg as needed. This was gradually reduced to a maintenance dosage of 180 mg/day. Three out of six patients were completely controlled, whereas the other three patients were partially controlled. Three out of six patients were seizure-free after the initial loading dose of PB. No adverse effects were found in this study. CONCLUSION In adult patients, enteral PB may be effective as an add-on for refractory SE therapy.

Abstract
Andrographolide (1) and 14-deoxy-11,12-didehydroandrographolide (2) are active constituents of Andrographis paniculata (Burm. f.), family Acanthaceae. A. paniculata extracts are reported to have antiviral, antipyretic, immunostimulant and anticancer activities. In this study, 1 and its 14-acetyl- (4) and 3,19-isopropylidenyl- (3) derivatives, as well as 2 and its 3,19-dipalmitoyl-derivative (5), were intraperitoneally tested for their analgesic, antipyretic, anti-inflammatory and acute toxicity effects in animal models. Analgesic effects were tested in mice using hot plate and writhing tests to distinguish the central and peripheral effects, respectively. The results showed that, at 4 mg/kg, all tested substances have significant analgesic effects, and the highest potency was seen with 3, 4 and 5. Increasing the dose of 3 and 5 to 8 mg/kg did not increase the analgesic effect. In the writhing test, 3 and 5, but not 1, showed significant results. In a baker's yeast-induced fever model, 3 and 5 significantly reduced rats' rectal temperature (p < 0.05). In a carrageenan-induced inflammation model, 1, 3 and 5 significantly reduced rats' paw volume. Doses of 3 and 5 up to 100 mg/kg did not show any serious toxic effects. From this study, 3 and 5 are the most interesting derivatives, showing much greater potency than their parent compounds. These could be further developed as analgesic, antipyretic and anti-inflammatory agents, without any serious toxicity.

Abstract
BACKGROUND Refractory status epilepticus (RSE), defined as status epilepticus that fails to respond to first, second and third-line therapy. The RSE is associated with high morbidity and mortality. Treatment guidelines of RSE give a spectrum of options, such as, continuous intravenous (i.v.) midazolam (MDL), or continuous i.v. propofol (PRO) as alternatives to phenobarbital (PB) or continuous i.v. pentobarbital (PTB). OBJECTIVE To study the efficacy of very-high-dose phenobarbital (VHDPB) for treatment RSE. STUDY DESIGN Retrospective study MATERIAL AND METHOD The authors collected and analyzed data from adult patients who were diagnosed with RSE. RESULTS The authors present 10 patients with RSE who were treated with VHDPB. All of them were generalized convulsive status epilepticus (GCSE). Ages ranged from 16-86 years old (mean.: 43 years). PB dosage ranged 40-140 mg/kg/day (mean: 70 mg/kg/day). The duration of status epilepticus (SE) varied widely, ranged 1-44 days (mean: 7 days). PB level ranged 35.29-218.34 ug/mL (mean 88.1 ug/mL). RSE was controlled by VHDPB 70%, 30% were not controlled. CONCLUSION VHDPB were considered as alternative treatment for RSE.

Abstract
BACKGROUND The medical students' knowledge about basic medical neuroscience in the preclinical level may be fragmented and incomplete. OBJECTIVE Evaluate the knowledge of students prior to a lecture on epilepsy in clinical level. MATERIAL AND METHOD One hundred ten fourth-year medical students' knowledge was accessed by a self-administered questionnaire. RESULTS The presented results revealed that 91.8% of respondents knew that epilepsy arose from a transient dysfunction in the brain. Generalized tonic-clonic seizures (GTCs) were the most common type (91.5%) they knew and absence seizures were the least common type (33.6%) they knew. All of them knew that eating pork and punishment of gods did not cause epilepsy. However 50% thought that genetics was a cause and 80.3% did not know that stroke and sleep deprivation (92.7%) cause epilepsy. About treatment and prognosis, only 28.2% of respondents thought epilepsy can be cured and patients should take antiepileptic drugs (AEDs) for seizure free 2-5 years (48.2%), life long (33.6%). They knew that the patients should be prohibited from driving (80%), working on machinery (74.5%), and (27.3%) avoid drinking. However, they knew that the patients could marry (100%), get pregnant (98.2%), and lactate (91.9%). Regarding the first aid management, 50.9% of them recommended that placing a piece of wood between the teeth during a seizure and perform chest compressions (20.0%). Means knowledge scores is about 60%, the highest score is the definition of epilepsy (90.2%) and the lowest is type of seizure (43%). CONCLUSION The findings indicated that lecturers should review aspects ofpathophysiology and emphasize on type of seizure, cause, consequences, and prognosis including first-aid management.

Abstract
Ocular angiostrongyliasis, diagnosed by identification of Angiostrongylus cantonensis in any part of the eye, is a very rare manifestation. We report seven cases of intraocular angiostrongyliasis in Srinagarind Hospital, Khon Kaen University, Thailand. From a total of 654 cases of angiostrongyliasis diagnosed between January 1995 and April 2005, 7 cases (1.1%) with ocular manifestations were found. Four men and three women were diagnosed, with a mean age of 32.1 years (range 21-46 years). All of the patients lived in the northeast of Thailand and acquired the infection by eating raw Pila spp. snails, the intermediate host of A. cantonensis. The incubation period lasted from 2 weeks to 2 months. The most common symptom, blurred vision without eosinophilic meningitis, occurred as a presenting symptom in five cases. The other two cases presented with eosinophilic meningitis prior to development of poor visual acuity. Both cases had papilloedema, neck stiffness and eosinophilia without fever. The visual acuity of the patient was mostly lower than 2/60 and, evidently, visual impairment in all patients was caused by retinal pigment epithelial defects. All cases had only one immature A. cantonensis worm in the eye, with the most common site being the intravitreous area. Several treatments, including oral prednisolone, topical prednisolone, argon laser, diode laser, Nd:YAG laser, surgical removal of the parasite and combination therapy, were used. There is no evidence that surgical and laser interventions improve the course of the disease, and both have associated risks. Visual outcome depends on the initial visual defects.

Abstract
OBJECTIVE To assess the frequency, characteristics, and risk of injury during seizure attacks. DESIGN Questionnaire survey. SETTING Epilepsy out-patient clinic of the National Hospital for Neurology and Neurosurgery, Institute of Neurology, London. PATIENTS One hundred consecutive epileptic patients and their caretakers or relatives, who attended the hospital between 1 May and 30 June 2000. MAIN OUTCOME MEASURES Details of epilepsy including the age of onset, causes, types, and number of seizures during the previous 12 months; injuries incurred as a result of seizures; and treatment required. RESULTS The mean age of the 100 patients (38 male, 62 female) was 39 years (range, 16-78 years). Generalised tonic-clonic seizures occurred in 51% of patients and complex partial seizures in 40%. Hippocampal sclerosis was found in 12% of patients. Twenty-seven patients reported 222 seizure-related injuries. The total number of seizures per year was 4459 (mean, 45), of which 1094 (mean, 11) were with a fall (24.5%). Soft-tissue injury was the most common (61%), followed by burns (17%), head injury (14%), orthopaedic injury (5%), and injuries in water (3%). The most common site of soft-tissue injury and burns were to the face: 49% and 38% respectively. Burns occurred during cooking in 78% of cases. Two patients had skull fractures. Orthopaedic injuries usually occurred at home (73%). In cases of seizures in water, five of six occurred while swimming. Injury occurred once in every 20 seizures, every 11 generalised tonic-clonic seizures, and every five seizures with a fall. The significant risk factors for injury were generalised tonic-clonic seizures, high frequency of seizures, and seizures with a fall. CONCLUSION Soft-tissue injury was the most common seizure-related injury. Injury occurred once in every 20 seizures. The risk factors were generalised tonic-clonic seizures, high frequency of seizures, and seizures with a fall.

Abstract
Myasthenia gravis and hypokalemic periodic paralysis are commonly related with hyperthyroidism but rarely occur together. Here, the authors reported a case of hypokalemic periodic paralysis in a Northeastern Thai woman accompanied with myasthenia gravis. She had motor weakness despite a normal level of serum potassium. Prostigmine test was positive. She dramatically improved after pyridostigmine treatment. Autoantibodies to nicotinic AchR-Ab and dihydropyridine receptor or L-type voltage gated calcium channel were postulated to explain these associated diseases.

Abstract
BACKGROUND Long-term levodopa usage in Parkinson's disease (PD) patients is known to cause several motor complications. It may be related to several factors such as levodopa dosage, duration of treatment and severity of disease. OBJECTIVE To study the prevalence of levodopa motor complications and associated factors in Thai Parkinson's disease patients. MATERIAL AND METHOD The authors prospectively collected baseline characteristics of PD patients, details of treatment and complications from 3 hospitals in various parts of Thailand. These patients were diagnosed by UK PD Brain Bank criteria. RESULTS A total of 154 patients aged 68.1 +/- 9.5 years were recruited. Age of onset was 61.2 +/- 9.8 years. Most patients were in Hoehn-Yahr stage 1-3. The common clinical features were bradykinesia, rigidity and resting tremor Treatments were levodopa (98.1 per cent), anticholinergic (29.9 per cent), dopamine agonists (26 per cent) and COMT inhibitor (9.1 per cent). Eighty-five per cent of the patients had excellent response to levodopa. However, 25 per cent of patients developed motor complications, which were wearing off (79 per cent), on-off fluctuation (45 per cent), freezing (42 per cent), morning dyskinesia (10.5 per cent) and permanent dyskinesia (23.7 per cent). Twelve patients developed severe levodopa induced chorea. Factors associated with levodopa side effects were earlier age of onset, long duration of disease, advanced stage, higher levodopa dosage and long duration of levodopa treatment. In the present study, age of onset was inversely correlated with H-Y stage, while dosage of levodopa was positively correlated with H-Y stage but inversely correlated with lower ADL score, which may be due to advanced disease state. CONCLUSION Levodopa motor complications are common in Thai PD patients. Wearing off on-off fluctuation and freezing are common forms of motor complications.

Abstract
OBJECTIVE The authors aimed to assess the frequency, characteristics, and risk of seizure-related injuries from traffic accidents, near-drowning, burns, fractures, head and soft tissue injuries. MATERIAL AND METHOD Attending physicians assisted 300 consecutive seizure patients to complete a questionnaire. The types and frequency of injuries were then expressed in terms of the type of seizure and related activity. RESULTS The male (154) and female (146) patients were between 13 and 91 years of age (mean, 36.27 +/- 14.55). The seizure types comprised of Generalized Tonic-Clonic (GTC) (26%), secondary GTCs (21%) and complex partials (19%). Secondary causes accounted for 34% of seizures, and post-stroke was the most common (25.5%). The total number of seizure events per year was 8,525 and of these 7,306 included a fall with soft tissue injury (70%), head injury (22%), near-drowning (3%), burns (3%) and fracture or dislocation (1%). The ranking of significant risk factors for injuries was: 1) GTC seizure; 2) seizure with a fall; and, 3) number of seizures. CONCLUSION Seizure-related injuries are common among Thai epileptic patients; thus, consistent treatment and education about the risk of injury would protect patients.

Abstract
The authors would like to evaluate the incidence, clinical manifestation, the appropriateness of treatment, and outcome of seizure at the emergency department (ED). All charts of patients who visited the ED of Srinagarind Hospital from 1 January 2003 to 31 December 2003 were reviewed. The profiles of patients and management at the ED were recorded. There were 33,508 cases who visited the ED with 104 cases (0.31%) presenting with seizure. Four cases (3.9%) were diagnosed as status epilepticus. Generalized tonic-clonic seizure was the most common type. Poor antiepileptic drug (AED) compliance with the low AED level was the main precipitating factor. The normal physical examination and routine laboratory tests were normal in the majority of patients. Phenytoin intravenous loading was the commonest initial treatment even in patients with non-status epilepticus. Fourteen patients (13.5%) were treated with intravenous diazepam even though seizures were discontinued. Sixty patients (57.7%) were discharged after seizure was controlled. The advice in seizure control was recorded in only 11 cases (10.6%). From this review, 12 patients presented at the ED for continuing medication without any seizures. In conclusion, seizure at the ED should be treated more appropriately with both laboratory investigation and drug treatment. Futhermore, patient education should be implemented.

Abstract
INTRODUCTION Epileptic patients face social stigmatization due to negative attitudes and incorrect knowledge on epilepsy. OBJECTIVES To evaluate knowledge of epilepsy among teachers in Khon Kaen province. MATERIAL AND METHOD A self-administered questionnaire distributed to 102 teachers who attended the training lectures on epilepsy. The number of correct responses for each item were collected. The statistical analysis included the percentage of correct response and the means of the total scores. RESULTS Most (78.4%) respondents understood that a seizure is an abnormal electrical discharge in the brain, while 54.9% thought it included a form of abnormal movement and 1% demonic possession. The generalized tonic-clonic seizure (GTCs) was the type of seizure with which most respondents were familiar (90.2%), while 23.5% had knowledge of absence seizures. The respondents identified the following as causes for epilepsy: 1) head injury (84%); 2) genetic disease (74.5%); 3) high fever (68%); and, 4) brain tumor (57%). A small minority associated epilepsy with eating pork (11%) and even fewer (2%) with a non-organic/non-physical cause. Only 16% of respondents thought epilepsy was incurable, and a quarter (27%) of the teachers thought epileptics required anti-epileptic drugs (AEDs) life long, while 20 and 9 percent believed patients would take AEDs for 3-6 months and only for episodes, respectively. About 57% of the teachers thought epileptics needed AEDs for 2-5 years. Most (77-79%) respondents thought epileptics were prohibited from using machinery or driving, and 63% thought alcohol would be prohibited. Almost two-thirds of the teachers (64%) thought they should try to place an object between the teeth of a person having an episode in order to prevent a biting injury to the tongue and 27% would restrain the person and perform chest compressions (CPR). The average total score for correct answers on the questionnaire was about 60% (29.26/50). Respondents generally understood that epilepsy is controllable (82%) and were able to identify a seizure (78.4%). The lowest scores were found in the section on identifying the types of seizures (37.8%). CONCLUSION Teachers' knowledge of epilepsy was incomplete; thus, an epilepsy education campaign is needed and should emphasize the types of seizures, the causes of epilepsy, and management.

Abstract
PURPOSE To compare the bioavailability of two clozapine formulations (100 mg Clozaril tablet from Novartis Pharmaceuticals UK Ltd., UK, as a Reference formulation and 100 mg Cloril tablet from Atlantic Laboratories Corp., Ltd., Thailand, as a Test formulation). The present study was conducted under real-life conditions in schizophrenic patients using a steady-state, multiple-dose, randomized crossover design to avoid the risk of adverse effects in healthy volunteers and pharmacokinetic difference between single and multiple-dose of the drug. METHODS The subjects received 100 mg bid of either the Reference formulation or the Test formulation for 7 days. At day-7 of each study phase, blood samples were collected at 0, 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 10 and 12 h after drug administration. Plasma was separated and stored at -80 degrees C until assay. The plasma concentration of clozapine was determined by high performance liquid chromatography. Pharmacokinetic parameters were calculated from the observed plasma-concentration time profiles. The bioequivalence between the two formulations was assessed by calculating individual peak plasma concentrations (Cmax) and area under the concentration-time curve (AUC(0-12 h)) ratios. RESULTS All subjects well tolerated both clozapine formulations. No serious side effects were reported. The Tmax, terminal half-life and the total plasma clearance of clozapine (uncorrected for bioavailability) observed in the present study were comparable to those observed in other previous reports. All of the pharmacokinetic parameters investigated in the present study calculated from the subjects after administration of Test and Reference formulations were close. The 90% confident interval for the ratio of means for the lnCmax (0.9784-1.0622) and lnAUC(0-12h) (0.9559-1.0441) are within the guideline range of bioequivalence (0.80 to 1.25). CONCLUSION The result demonstrated that the Test formulation was bioequivalent to the Reference formulation (Clozaril) when orally administered in schizophrenic patients, in terms of both the rate and extent of absorption.

Abstract
A novel synthetic approach towards N1-alkylated 3-propyl-1,4-benzodiazepines was developed in five synthetic steps from 2-amino-4-chlorobenzophenone, in which the N-oxide 4 served as a key intermediate. The structure-activity relationship optimization of this 3-propyl-1,4-benzodiazepine template was carried out on the N1-position by selective alkylation reactions and resulted in a ligand with an improved affinity on the cholecystokinin (CCK2) receptor. The N-allyl-3-propyl-benzodiazepine 6d displayed an affinity towards the CCK2 (CCK-B) receptor of 170 nM in a radiolabelled receptor-binding assay. The anxiolytic activity of this allyl-3-propyl-1,4-benzodiazepine 6d was subsequently determined in in-vivo psychotropic assays. This novel ligand had ED50 values of 4.7 and 5.2 mg kg(-1) in the black and white box test and the x-maze, respectively, and no significant sedation/muscle relaxation was observed.

Abstract
Tuberculous meningitis (TBM) is a common manifestation of extrapulmonary tuberculosis. Syringomyelia is a rare complication of TBM. We report a case of syringomyelia due to TBM. A 25 year old Thai male was admitted with a history of progressive paraparesis and loss of body sensation. He had a history of TBM in the previous year, and was treated with antituberculous drugs. Physical examination revealed a temperature of 37 degrees C. Motor power was grade 3/5 with generalized hyperreflexia. He had bilateral loss of pain, temperature and vibratory sensation below the T7 level. A magnetic resonance imaging of the spine demonstrated a long segment of syrinx from C4 to the conus medullaris region. A T12-L1 laminectomy and syringosubarachnoid shunt were done. His clinical symptoms improved after surgery.

Abstract
The Hallervorden-Spatz syndrome (HSS) is a rare condition characterized by extrapyramidal and pyramidal signs, dystonia, dysarthria, retinal degeneration, dementia and a progressive course. The development of magnetic resonance imaging (MRI) has increased the number of clinical and pathological reports of HSS. MRI pallidal abnormalities are called "eye of the tiger" signs. The combination of clinical features and MRI findings can be considered as highly suggestive of a diagnosis of HSS. Patient 1 was a 28 year old man who had been well until the age of 25 years. He developed dysarthria, difficulty with his gait and dystonia in his arms at the age of 28 years. Patient 2 was a 33 year old man who was the older brother of the first patient. He developed gait difficulty, tongue dystonia and dystonia of both arms at the age of 25 years. Each patient had spastic gait, dysarthria, dystonic posturing of both arms and generalized hyperreflexia, but no Kayser-Fleischer rings or retinitis pigmentosa. Blood chemistry, urine copper, serum copper and serum ceruloplasmin were all normal. MRI of the brain showed the "eye of the tiger" sign in the globus pallidus on T2 weighted images. These siblings had clinical features and MRI findings consistent with HSS. They are the first to be reported in Thailand.

Abstract
Downbeating nystagmus is an involuntary vertical rhythmic eye movement with the fast component in the downward direction. The sign indicates a craniocervical disorder. The most common cause is the Arnold-Chiari malformation, followed by cerebellar degeneration. Basilar invagination is a rare cause of downbeating nystagmus. However, with appropriate treatment its prognosis is good. Here, we report a case of basilar invagination which presented with downbeating nystagmus and postural hypotension. A 31 year-old Thai male patient had a 20 year history of postural hypotension. He had recurrent pneumonia and cough-induced syncope a year before admission. He complained of symptoms of an acute febrile illness and a productive cough. The physical examination showed high grade fever, postural hypotension and medium crepitation in the right upper lobe. The neurological examination showed downbeating nystagmus, atrophy and fasciculation of the right side of the tongue, atrophy of the right sternocleidomastoid muscle, mild weakness of the extremities and generalized hyperreflexia. The cervical spine X-ray revealed upward displacement of the vertebral bodies of C1 and C2, with a mild narrowing of the space between C1 and the occiput. The CT-myelogram and MRI showed upward displacement of C1 with overriding of the dens over the anterior lip of the foramen magnum; this also compressed the medulla. Syringomyelia was seen at the C1-C5 level. We report a patient who presented with postural hypotension, recurrent pneumonia and downbeating nystagmus due to basilar invagination. The symptoms were aggravated by cough which caused an increase in intracranial pressure. This resulted from medulla compression in the foramen magnum by the first cervical spine. The treatment of choice was surgical decompression.

Abstract
Pseudotumor cerebri is a condition characterized by increased intracranial pressure with normal cerebrospinal fluid composition. It is usually associated with many medical conditions and drugs. It has been reported that all-trans-retinoic acid can induce pseudotumor cerebri. The authors report a 35-year-old patient diagnosed with acute promyelocytic leukemia who developed pseudotumor cerebri after receiving all-trans-retinoic acid. The patient was treated with 60 mg/day of all-trans-retinoic acid. Two weeks later, she had severe headache and blurred vision. The neurological examination revealed papilledema and decreased visual acuity. Other physical examinations were unremarkable. Brain CT was normal. Additionally, lumbar puncture was performed and the CSF finding was normal except for high CSF pressure. According to modified Dandy criteria, the diagnosis was pseudotumor cerebri. The patient's symptoms disappeared after all-trans-retinoic acid was discontinued. To our knowledge, this is the first case report in Thailand.

Abstract
Eosinophilic meningoencephalitis is prevalent and widely distributed in Thailand, especially in the northeastern and central parts of the country. Angiostrongylus cantonensis is one of the causative agents of fatal eosinophilic meningoencephalitis. The nematodes produce extensive tissue damage by moving through the brain and inducing an inflammatory reaction. We report the clinical features and the findings revealed by MR imaging and MR spectroscopy in six patients with eosinophilic meningoencephalitis. The clinical presentation included severe headache, clouded consciousness, and meningeal irritation. Abnormal findings on MR images included prominence of the Virchow-Robin spaces, subcortical enhancing lesions, and abnormal high T2 signal lesions in the periventricular regions. Proton brain MR spectroscopy was performed in three patients and was abnormal in one severe case, showing decreased choline in a lesion. Small hemorrhagic tracts were found in one case. Lesions thought to be due to microcavities and migratory tracts were found in only one case. We believe the MR imaging and MR spectroscopy findings are of diagnostic value and helpful in understanding the pathogenetic mechanisms of the disease.

Abstract
OBJECTIVE To describe the long term efficacy and side effects of the treatment of hemifacial spasm with Dysport and to evaluate two different sites of injection to hopefully reduce side effects. METHODS This study was designed as a prospective descriptive study. Injections were made subcutaneously around the eye. Peak improvement was subjectively assessed by using a visual analogue scale and reported in percentages (0-100%). Duration of improvement was assessed subjectively and reported in months. RESULTS Of 175 cases, 17 were lost to follow up and were excluded. 855 treatments were injected in the remaining 158 patients with a median of 4 treatments. The response rate was 97%. Of 855 treatments, the adjusted mean peak and duration of improvement was 77.2 (95% confidence interval (95%CI) 74.7-79.4)% and 3.4 (95%CI 3.2-3.6) months respectively. In 158 patients (complete group), the long term results from the first to the 12th treatment showed that the mean peak improvement ranged from 72.70 to 80.10% and the duration of improvement was 2.60 to 3.71 months. It remained constant throughout (p=0.40, p=0.87 respectively). The most common side effect was ptosis. Of the 158 patients, 21 completed 12 treatments (subgroup). A separate analysis of this group disclosed a mean peak and duration of improvement from the first to 12th treatments ranging from 70.00 to 78.10% and 2.65 to 4.31 months respectively. Analysis of variance with repeated measures showed no significant variation of peak and duration of improvement over the first to the 12th treatments (p=0.38, p=0.38 respectively). Only 3% of the treatments were unsuccessful but responded to subsequent treatments. The incidence of ptosis was reduced from 27.17% to 9.68% by moving the injection site to the lateral part of orbital orbicularis oculi without any loss of efficacy. The yearly cost of Dysport is considerably less than Botox. CONCLUSION This study is the first to show, in detail, the long term results of treatments of hemifacial spasm with Dysport. The efficacy is constant throughout orbicularis oculi. The efficacy of Dysport is comparable with Botox in long term follow up.
