RESUMO
BACKGROUND: Previous studies have established familial occurrence of epilepsy and seizure disorders and early age of epilepsy onset as predictors of genetic epilepsy, but have not evaluated the rate of their occurrence in patients with different epilepsy etiology. Our study determines the distribution of familial occurrence and age of epilepsy onset across structural focal epilepsy (FE) etiology in a large FE cohort. METHODS: Records of 1354 consecutive patients evaluated for epilepsy and seizure disorders in The Neurology Clinic, University Clinical Center of Serbia from 2008 to 2019 were screened for FE. Structural etiology, lobar diagnosis, familial occurrence, and age at epilepsy onset were determined. Patients with a. nonlesional focal epilepsy (NLFE), b. hippocampal sclerosis (HS) and c. congenital or perinatal etiology (CPE) were classified as NAFE, while patients with an identified acquired focal epilepsy (AFE) constituted the control group. RESULTS: We identified 965 patients with FE, 329 (34.1 %) with NLFE, 213 (22.1 %) with HS, 174 (18.0 %) with CPE and 249 (25.8 %) with AFE. Familial occurrence was identified in 160 (16.6 %), 19.1 % of patients with NAFE and 9.2 % of AFE (p = 0.003). Patients with NAFE had a younger age of epilepsy onset (13 vs. 18 years, p < 0.001). The highest proportion of familial occurrence was found in patients with NLFE (23.7 %), while the youngest median age of epilepsy onset was identified in patients with HS (12 years) and CPE (11 years). CONCLUSION: Patients with NAFE frequently have familial occurrence of epilepsy and have an earlier age of epilepsy onset than patients with AFE.

PURPOSE: In a homogeneous cohort of mesial temporal lobe epilepsy (mTLE) patients with hippocampal sclerosis (HS), this study utilizes the PETSurfer method to quantify and localize areas of cerebral hypometabolism. METHODS: We selected patients from the University Clinical Center of Serbia who all underwent anterior temporal lobectomy with amygdalohippocampectomy and achieved seizure freedom (Engel class I). Our analysis involved integrating FDG-PET and MRI imaging to compare glucose metabolism between the hemispheres ipsilateral and contralateral to HS. RESULTS: The quantitative PETSurfer approach identified significant hypometabolism restricted to the ipsilateral temporal lobe structures-the amygdala, hippocampus, temporal pole, superior and middle temporal gyrus-and the ipsilateral thalamus. The lack of significant hypometabolism in extratemporal regions indicates that these 'pure' mTLE cases may not involve the broader network disruptions typically associated with more extensive epileptic pathologies. The effect sizes ranged from small to medium, indicating variable degrees of metabolic reduction across different structures. CONCLUSION: These findings highlight the localized nature of the epileptogenic focus in HS-related mTLE with good surgical outcome. However, the small sample size and potential cohort bias, necessitate caution in generalizing these results. Future research would benefit from a comparative approach incorporating a control group, providing a broader context for interpreting these hypometabolic patterns.

OBJECTIVE: To evaluate the psychometric properties of the Serbian-language version of the Stigma Scale of Epilepsy (SSE). METHODS: The sample consisted of 108 patients with epilepsy (PWE) (60.2 % were female, age range: 19-67 years) and 102 students (86.3 % were female, age range: 18-47 years). The study encompassed two phases: (1) translation of the SSE into Serbian using the back-translation technique, and (2) evaluation of reliability and construct validity of the Serbian-language version of SSE. In addition to the SSE, the PWE filled out a Neurological Disorders Depression Inventory for Epilepsy (NDDI-E), Patient Health Questionnaire-9 (PHQ-9), and Generalized Anxiety Disorder-7 (GAD-7). The socio-demographic and clinical variables were noted for each patient by the semistructured interview. Besides completing the SSE, the students were asked if they knew anyone with epilepsy. The reliability of the questionnaire was tested by assessing the internal consistency of the scale (Cronbach's α), while construct validity was assessed by factor analysis, method of known-groups validation, and correlation analysis. RESULTS: SSE demonstrates a satisfactory level of reliability in both samples, with Cronbach's α of 0.86 in the PWE sample and 0.90 in the student sample. Using exploratory factor analysis, four factors were identified in both samples, corresponding relatively well with the scale domains originally produced, with a few exceptions described. Adverse effects (AEs) of antiseizure medications (ASMs) and driving ability significantly influenced SSE scores, but there were no significant effects of other socio-demographic and clinical variables on epilepsy-related stigma in the PWE sample. In addition, depression severity significantly influenced SSE scores (based on NDDI-E cut-off score), with the SSE showing a positive association with PHQ-9 (r = 0.42, p < .001) and GAD-7 (r = 0.35, p < .001) as well. Regarding the student sample, the effects of personal knowledge of someone with epilepsy on SSE scores were found to be significant. Besides, students (M = 46.28, SD = 16.43) reported higher epilepsy-related stigma than patients (M = 40.66, SD = 17.01), t(208) = 2.43, p < .05, d = 0.34. CONCLUSION: The Serbian version of the SSE has good psychometric properties and represents a useful tool for assessing epilepsy-related stigma in both patients and the general population.

Every third patient with intracranial meningioma develops seizures of poorly understood etiology. Tumor and peritumoral edema may exert mechanical pressure on the cortex that may affect mechano-gated potassium channels - KCNK2 and KCNK4. These channels regulate neuron excitability and have been related to seizures in some other conditions. The objective of the present study was to explore a potential relation between the levels of these proteins in tumor tissue and adjacent cortex and seizures development. The study included 19 meningioma patients that presented one or more preoperative seizures and 24 patients with no seizures. Tissue samples were collected in the course of surgical removal of the meningioma. Postoperative seizure freedom was achieved in 11 out of 19 patients. The relative level of KCNK2 in the cortical tissue was lower in patients with preoperative seizures. On the other hand, cortical tissue level of KCNK4 was higher in patients that became seizure-free after the surgery. In addition, relative levels of KCNK4 in the cortical and tumor tissue appear to be lowered by the treatment with anti-seizure medication levetiracetam. These results imply that KCNK2 and KCNK4 may be involved in the development of meningioma-related seizures and may represent promising therapeutic targets.
RESUMO
INTRODUCTION: Next generation sequencing (NGS) has greatly expanded our understanding of genetic contributors in multiple epilepsy syndromes, including focal epilepsy. Describing the genetic architecture of common syndromes promises to facilitate the diagnostic process as well as aid in the identification of patients who stand to benefit from genetic testing, but most studies to date have been limited to examining children or adults with intellectual disability. Our aim was to determine the yield of targeted sequencing of 5 established epilepsy genes (DEPDC5, LGI1, SCN1A, GRIN2A, and PCHD19) in an extensively phenotyped cohort of focal epilepsy patients with normal intellectual function or mild intellectual disability, as well as describe novel variants and determine the characteristics of variant carriers. PATIENTS AND METHODS: Targeted panel sequencing was performed on 96 patients with a strong clinical suspicion of genetic focal epilepsy. Patients had previously gone through a comprehensive diagnostic epilepsy evaluation in The Neurology Clinic, University Clinical Center of Serbia. Variants of interest (VOI) were classified using the American College of Medical Genetics and the Association for Molecular Pathology criteria. RESULTS: Six VOI in eight (8/96, 8.3%) patients were found in our cohort. Four likely pathogenic VOI were determined in six (6/96, 6.2%) patients, two DEPDC5 variants in two patients, one SCN1A variant in two patients and one PCDH19 variant in two patients. One variant of unknown significance (VUS) was found in GRIN2A in one (1/96, 1.0%) patient. Only one VOI in GRIN2A was classified as likely benign. No VOI were detected in LGI1. CONCLUSION: Sequencing of only five known epilepsy genes yielded a diagnostic result in 6.2% of our cohort and revealed multiple novel variants. Further research is necessary for a better understanding of the genetic basis in common epilepsy syndromes in patients with normal intellectual function or mild intellectual disability.

PURPOSE: We conducted an observational study to investigate the opinions of neurologists and psychiatrists all around the world who are taking care of patients with seizures [epilepsy and functional seizures (FS)]. METHODS: Practicing neurologists and psychiatrists from around the world were invited to participate in an online survey. On 29th September 2022, an e-mail including a questionnaire was sent to the members of the International Research in Epilepsy (IR-Epil) Consortium. The study was closed on 1st March 2023. The survey, conducted in English, included questions about physicians' opinions about FS and anonymously collected data. RESULTS: In total, 1003 physicians from different regions of the world participated in the study. Both neurologists and psychiatrists identified "seizures" as their preferred term. Overall, the most preferred modifiers for "seizures" were "psychogenic" followed by "functional" by both groups. Most participants (57.9%) considered FS more difficult to treat compared to epilepsy. Both psychological and biological problems were considered as the underlying cause of FS by 61% of the respondents. Psychotherapy was considered the first treatment option for patients with FS (79.9%). CONCLUSION: Our study represents the first large-scale attempt of investigating physicians attitudes and opinions about a condition that is both frequent and clinically important. It shows that there is a broad spectrum of terms used by physicians to refer to FS. It also suggests that the biopsychosocial model has gained its status as a widely used framework to interpret and inform clinical practice on the management of patients.

Oral lacerations are common complications of seizures and account for 92% of all oral injuries. Seizures are relatively commonly associated with chronic alcohol consumption. It is already known that provoked seizures can occur after a sudden cessation of prolonged alcohol intoxication. Meanwhile, chronic alcohol consumption can disrupt the blood coagulation process on several levels. This report aims to present a case of generalized tonic-clonic seizure in a man with chronic alcoholism and acquired coagulopathy who suffered severe tongue injury during a seizure. A 45-year-old man was brought to the emergency department after a first-in-life generalized tonic-clonic seizure. He gave information that he bit his tongue during the seizure. Shortly afterward, the patient had another generalized seizure during which he stopped breathing and was intubated. On admission, the patient was sedated, intubated, and on mechanical ventilation, with no signs of focal neurological deficit. A detailed physical examination revealed massive tongue swelling, which was significantly moved forward. Laboratory tests revealed coagulopathy (INR 2,10) severe thrombocytopenia with a platelet count of 50x109/L. Electrolyte values were in the reference range. According to the maxillofacial surgeon's recommendation, he was treated conservatively, and after 2 weeks, he was clinically stable with a significant reduction of lingual hematoma and without new epileptic events. In our case, decreased platelet count and probable platelet dysfunction associated with chronic alcohol consumption and tongue bite during generalized tonic-clonic seizure played a significant role in developing lingual hematoma. These fast-developing lingual hematomas can lead to possible airway obstruction; therefore, careful observation and timely intubation are mandatory to prevent possible fatal complications.
RESUMO
OBJECTIVE: Risk factors for epilepsy in meningioma patients are not yet clearly defined, however, seizure freedom is a significant factor for quality of life after surgery. METHODS: We performed a retrospective study of the 333 adult patients who received surgery for supratentorial meningioma at our center. Various clinical, radiological, and surgical variables were included in the multivariate regression, and the outcomes measured were the occurrence of seizure(s) preoperatively, during the hospitalization, and during the follow-up period. RESULTS: A total of 89 (26.7%) patients experienced preoperative seizures, of whom 62.9% were seizure free after the surgery. Of 244 patients without epilepsy before surgery, 11.9% had at least one seizure postoperatively. In total, 63 of our patients (18.9%) experienced seizures after the surgery, of whom 20 had refractory epilepsy. Multivariate analysis identified the following predictors of preoperative seizures: the absence of headache (OR: 0.23, CI: 2.55-8.50), the presence of significant peritumoral edema (OR: 4.35, CI: 2.57-7.35), and younger age (OR: 0.97 per year increase, CI: 0.95-0.99). Factors associated with early postoperative seizures were: younger age (OR: 0.96 per year increase, CI: 0.93-0.99) and the presence of preoperative seizures (OR: 2.73, CI: 1.13-6.57), while the presence of preoperative seizures (OR: 4.73, CI: 2.05-10.92), tumor progression (OR: 5.38, CI: 2.25-12.89), and neurological worsening (OR: 5.21 CI: 1.72-15.81) were significant for late postoperative seizures. SIGNIFICANCE: Our results from a single-center meningioma cohort confirm, in general, data from some previous studies regarding patients' characteristics for both preoperative and overall postoperative epilepsy. Besides previously described risk factors, younger age was important for preoperative and early postoperative seizures. Epilepsy is common in patients with recurrence of meningioma, but the variables of significance for refractory seizures in these patients require further examination.

INTRODUCTION: Variants in GATOR1 genes are well established in focal epilepsy syndromes. A strong association of GATOR1 variants with drug-resistant epilepsy as well as an increased risk of sudden unexplained death in epilepsy warrants developing strategies to facilitate the identification of patients who could potentially benefit from genetic testing and precision medicine. We aimed to determine the yield of GATOR1 gene sequencing in patients with focal epilepsy typically referred for genetic testing, establish novel GATOR1 variants and determine clinical, electroencephalographic, and radiological characteristics of variant carriers. PATIENTS AND METHODS: Ninety-six patients with clinical suspicion of genetic focal epilepsy with previous comprehensive diagnostic epilepsy evaluation in The Neurology Clinic, University Clinical Center of Serbia, were included in the study. Sequencing was performed using a custom gene panel encompassing DEPDC5, NPRL2, and NPRL3. Variants of interest (VOI) were classified according to criteria proposed by the American College of Medical Genetics and the Association for Molecular Pathology. RESULTS: Four previously unreported VOI in 4/96 (4.2%) patients were found in our cohort. Three likely pathogenic variants were determined in 3/96 (3.1%) patients, one frameshift variant in DEPDC5 in a patient with nonlesional frontal lobe epilepsy, one splicogenic DEPDC5 variant in a patient with nonlesional posterior quadrant epilepsy, and one frameshift variant in NPRL2 in a patient with temporal lobe epilepsy associated with hippocampal sclerosis. Only one VOI, a missense variant in NPRL3, found in 1/96 (1.1%) patients, was classified as a variant of unknown significance. CONCLUSION: GATOR1 gene sequencing was diagnostic in 3.1% of our cohort and revealed three novel likely pathogenic variants, including a previously unreported association of temporal lobe epilepsy with hippocampal sclerosis with an NPRL2 variant. Further research is essential for a better understanding of the clinical scope of GATOR1 gene-associated epilepsy.

BACKGROUND: MCPH1 is known as the microcephalin gene (OMIM: *607117), of which the encoding protein is a basic regulator of chromosome condensation (BCRT-BRCA1 C-terminus). The microcephalin protein is made up of three BCRT domains and conserved tandem repeats of interacting phospho-peptides. There is a strong connection between mutations of the MCPH1 gene and reduced brain growth. Specifically, individuals with such mutations have underdeveloped brains, varying levels of mental retardation, delayed speech and poor language skills. METHODS: In this article, a family with two affected fetuses presenting a mutation of the MCPH1 gene is reported. During the first trimester ultrasound of the second pregnancy, the measure of nuchal translucency was increased (NT = 3.1 mm) and, therefore, the risk for chromosomal abnormalities was high. Chorionic villi sampling (CVS) was then performed. Afterwards, fetal karyotyping and Next Generation Sequencing were carried out. Afterwards, NGS was also performed in a preserved sample of the first fetus which was terminated due to microcephaly. RESULTS: In this case, the fetuses had a novel homozygous mutation of the MCPH1 gene (c.348del). Their parents were heterozygous for the mutation. The fetuses showed severe microcephaly. Because of the splice sites in introns, this mutation causes the forming of dysfunctional proteins which lack crucial domains of the C-terminus. CONCLUSION: Our findings portray an association between the new MCPH1 mutation (c.348del) and the clinical features of autosomal recessive primary microcephaly (MCPH), contributing to a broader spectrum related to these pathologies. To our knowledge, this is the first prenatal diagnosis of MCPH due to a novel MCPH1 mutation.
RESUMO
INTRODUCTION: The Internet and social media are becoming increasingly important medical information sources, bringing advantages and disadvantages. The extent of social media use may help to develop a strategy for providing relevant information, enhancing patients' social status, and the work of medical practitioners in chronic medical conditions such as epilepsy. AIM: The aim of this study was to help better understand the factors of social media that may affect patients' knowledge of the disease, health education, emotional stability, thinking, and decisions in the treatment process. MATERIAL AND METHODS: We studied the representation of epilepsy among social media users in Serbian, Croatian, and Bosnian languages. Our observational study analyzed 1000 randomized posts and videos on Facebook, Twitter, and YouTube, containing the keywords "epilepsy" or "seizure." Posts were divided into three categories: topics, data sources, and the nature of the engagement. RESULTS: The most common topic among social media users was the stigmatization of patients (31%). The most prevalent data source was support groups for PWE (45.4%). The nature of the engagement was most dominant on the occasion of the exchange of information, i.e., advice (40%). CONCLUSION: The participation of medical professionals on social media is not adequately represented in Serbian, Croatian, and Bosnian language platforms. The presence of medical professionals on social media could increase the credibility of the information available to users, educate patients, and reduce the prevalence of stigma.

OBJECTIVE: To perform a follow-up study of the quality of life in patients with epilepsy in the era of the COVID-19 crisis. METHODS: Two months before the first case of the COVID-19 in Serbia, we obtained the Serbian Version of Quality of Life Inventory for Epilepsy 31 (SVQOLIE-31) and Neurological Disorders Depression Inventory for Epilepsy scores (SVNDDI-E) for another study. We retested the same patients one year after in COVID-19 pandemic. In addition to SVQOLIE-31, and SVNDDI-E we used a generic questionnaire compiled from items related to the COVID-19. RESULTS: We retested 97 out of 118 patients (82.2%) for the follow-up analysis. The average age was 36.1⯱â¯12.2 (range: 18-69), and 49 were women (50.5%). The median duration of epilepsy was 13â¯years (range: 1.5-48). The structural etiology of epilepsy was noted in 41 (42.3%), unknown etiology in 41 (42.3%), and genetic etiology in 15 (15.4%) patients. Fewer patients (27.8%) experienced at least one seizure three months before follow-up testing when compared to patients who experienced at least one seizure three months in initial testing (36.0%) (pâ¯=â¯0.15). All patients reported full compliance with anti-seizure medication in the follow-up. The SVQOLIE-31 score during the COVID-19 pandemic visit (64.5⯱â¯14.6) was significantly lower than the SVQOLIE-31 score before the pandemic (pâ¯<â¯0.001). The SVNDDI-E score during the COVID-19 pandemic (10.5⯱â¯3.5) was significantly higher than the SVNDDI-E score before it (pâ¯<â¯0.001). Multiple linear regression analyses revealed fear of seizures, and fear of a reduction in household income, significantly associated with SVQOLIE-31 and SVNDDI-E overall score. These variables accounted for 66% and 27% of the variance of SVQOLIE-31 and SVNDDI-E overall score. SIGNIFICANCE: Lower quality of life, higher prevalence of depression, healthcare availability issues, and perceived fears during pandemic all suggest COVID-19 has negatively impacted lives of patients with epilepsy.

Epitheliod trophoblastic tumor (ETT) account for only 1-2% of all the cases of gestational trophoblastic neoplasia (GTN), with a reported mortality rate of 10-24%. ETT is derived from chorionic type intermediate trophoblastic cells, which appears to be the reason for the only slightly elevated ßhCG levels in these patients. We present a case of a 42-year-old patient who was admitted to the clinic eight months after Caesarean delivery, for irregular vaginal bleed with normal values of beta-human chorionic gonadotropin (ßhCG). A 6 × 5 cm hematoma was evacuated from the isthmic uterine segment during the operation, and the histopathological exam of the tissue surrounding the hematoma revealed ETT. There were no metastatic lesions on the thoracal, abdominal, and pelvic CT. The second ultrasonographic exam revealed tumefaction of 5 cm at the site from the previous surgical procedure. Color Doppler imaging revealed no central nor peripheral blood flow. The patient underwent a total abdominal hysterectomy with bilateral adnexectomy without adjuvant chemotherapy. This appears to be one of the shortest intervals from the anteceded gestational event until the diagnosis of this tumor, along with the absence of the significant ultrasonographic feature of the ETT-peripheral Doppler signal pattern. We underline that, even with normal values of ßhCG, irregular vaginal bleeding following the antecedent gestational event should always arouse suspicion of GTN.

The aim of this study was to determine whether the occurrence of focal to bilateral motor seizures in the course of partial drug withdrawal during video-EEG monitoring (FTBMS-M) had a predictive value for seizure recurrence in surgically treated patients with mesial temporal lobe epilepsy (MTLE). We analyzed the outcomes of 59 patients who underwent temporal lobe resection at 12 month postoperative follow up. In total, 48 out of 59 patients were rendered seizure free (81.4%). We analyzed seizure recurrence after surgery with reference to: (i) occurrence of seizures after partial drug withdrawal during video-EEG monitoring (FTBMS-M); (ii) history of secondarily generalized seizures during antiepileptic drug treatment prior to presurgical evaluation (FTBMS-H) and (iii) other possible confounding factors (sex, age, epilepsy duration, side of surgery, presence of hippocampal sclerosis, and history of febrile seizures). We found no differences in the frequency of seizure recurrences between patients with FTBMS-M and patients without FTBMS-M (4/20 vs. 7/39; p = 0.848). Conversely, the frequency of seizure recurrence was significantly higher among the patients with FTBMS-H than among the patients without FTBMS-H (7/20 vs. 4/39; p = 0.021). The predictive value of FTBMS-H for postoperative seizure recurrence was confirmed in logistic regression analysis. We found a statistically significant influence of FTBMS-H on poor outcome after surgery, but not of FTBMS-M or other confounding variables, which suggests that withdrawal seizures do not affect postsurgical seizure control.

The article examines the patient-doctor relationship, relying on Michel Foucault's concept of the clinical gaze. We argue that during the last decades, a profound transformation of the social nature of medicine took place, one that Foucault's understanding of the clinical gaze cannot adequately account for. First, the article offers an elaboration of the three-node network of clinical gaze, the clinic, and nosology to explain the positioning of the doctor and the patient within the specific social ontology generated by the rise of medicine. We then discuss intensive but irresolute developments brought by technological advancements, especially the X-ray tube. Finally, we argue that in the contemporary clinic, equipped with a plethora of sophisticated devices, the position of the doctor endured the most radical transformation in comparison with Foucault's proponent of the clinical gaze at the dawn of modern medicine.

Low-grade epilepsy-associated neuroepithelial tumours (LEATs) encompass the broad spectrum of tumours associated with epilepsy. Since the postsurgical seizure outcome in LEATs is favourable, it is speculated that epileptological presurgical evaluation (EPE) might not be required for patients with LEATs. A multicentre study involving referring epilepsy and neurosurgery centres was performed, aimed at evaluating postsurgical epilepsy outcome in patients with LEATs, with and without EPE, including long-term video-EEG monitoring (vEEGM). In total, 149 surgically treated patients were enrolled (age: 31±14 years; age at surgery: 26.4±13.1 years; males; 55.7%) with histopathological confirmation of LEATs and follow-up of more than six months. All patients had undergone standard assessment: clinical, routine EEG and brain MRI. In addition to vEEGM, EPE included other additional investigations. Epileptologists did not assess patients treated in neurosurgical centres. The EPE was performed in 51% of patients. Histopathological diagnosis revealed ganglioglioma in 43.6%, DNET in 32.9%, pilocytic astrocytoma in 17.4%, and others in 6.1% of patients. The majority of patients were seizure-free (ILAE epilepsy surgery outcome Class 1; 71.1%). The median follow-up period was 36 months. Patients who were rendered seizure-free were younger (mean age: 24.2±12.2) than those who were not seizure-free (31.8±14.0) (p=0.001). No difference was identified between evaluated and non-evaluated patients with respect to seizure freedom (p=0.45). EPE patients had a longer epilepsy duration (median: 10 years) and a higher proportion of drug resistance (73.6%) compared to non-evaluated patients (median: two years; 26.4%) (p<0.001). Based on a significant difference in major clinical variables, that may well affect postoperative results, the similar postsurgical seizure outcome in groups with and without EPE observed in our study should be considered with caution, and conclusions as to whether there is value in formal presurgical evaluation in LEAT patients cannot be drawn. Our data strongly encourage the clear need for continued discussion around such patients at epilepsy management conferences.

The aim of this study was to determine whether the occurrence of focal-to-bilateral motor seizures in the course of partial drug withdrawal during video-EEG monitoring (FTBMS-M) had a predictive value for seizure recurrence in surgically treated patients with mesial temporal lobe epilepsy (MTLE). We analyzed the outcomes of 59 patients who underwent temporal lobe resection and had postoperative follow-up from 6 to 58 months. In total, 48 out of 59 patients were rendered seizure free (81.4%). We analyzed seizure recurrence after surgery with reference to: (i) occurrence of seizures after partial drug withdrawal during video-EEG monitoring (FTBMS-M); (ii) history of secondarily generalized seizures during antiepileptic drug treatment prior to presurgical evaluation (FTBMS-H) and (iii) other possible confounding factors (sex, age, epilepsy duration, side of surgery, presence of hippocampal sclerosis, and history of febrile seizures). We found no differences in the frequency of seizure recurrences between patients with FTBMS-M and patients without FTBMS-M (4/20 vs. 7/39; p = 0.848). Conversely, the frequency of seizure recurrence was significantly higher among the patients with FTBMS-H than among the patients without FTBMS-H (7/20 vs. 4/39; p = 0.021). The predictive value of FTBMS-H for postoperative seizure recurrence was confirmed in logistic regression analysis. We found a statistically significant influence of FTBMS-H on poor outcome after surgery, but not of FTBMS-M or other confounding variables, which suggests that withdrawal seizures do not affect post-surgical seizure control.
RESUMO
The Liverpool Adverse Event Profile (LAEP) is a useful instrument in assessing the consequences of adverse events in patients using antiseizure medication. The LAEP scale has been validated in several languages to date. The aim of our study was to validate the LAEP scale in the Serbian language (SVLAEP). Validation of the SVLAEP scale was conducted by translating the original English version into the Serbian language and backtranslated into the English language. The translation was accepted when the two versions of the text were compatible. The questionnaire is then given to a group of patients with epilepsy treated with a stable dose of antiseizure medication. For the assessment of the quality of life and depression, we used the Serbian version of the Quality of Life in Epilepsy Inventory-31 (SVQOLIE-31) and the Serbian version of the Neurological Disorders Depression Inventory for Epilepsy (SVNDDI-E). From a total of 166 patients, 118 patients were included, and the remaining 48 were excluded because of other comorbidities and using other psychotropic drugs. Internal consistency (Cronbach's αâ¯=â¯0.87) and test-retest reliability (intraclass correlation coefficient (ICC)â¯=â¯0.80) were satisfactory. The SVLAEP and SVQOLIE-31 had a strong negative statistical correlation (rsâ¯=â¯-0.73; pâ¯<â¯0.001). The SVLAEP and SVNDDI-E final scores had a positive moderate correlation (rsâ¯=â¯0.52; pâ¯<â¯0.001). A moderate negative statistical correlation was found between SVNDDI-E and SVQOLIE-31 (rsâ¯=â¯-0.56; pâ¯<â¯0.001). Our study showed that the LAEP scale is a useful indicator for the frequency of the adverse events in antiepileptic drug (AED) usage, despite a minor overlap with the symptoms of depression.
