Translation to Portuguese and cross-cultural adaptation of the epilepsy transition readiness checklist for use in Brazil.

OBJECTIVES: Planning for the child and adolescent to have a safe handling in the epilepsy transition process is essential. In this work, the authors translated the "Readiness Checklists" and applied them to a group of patients and their respective caregivers in the transition process to assess the possibility of using them as a monitoring and instructional instrument. METHODS: The "Readiness Checklists" were applied to thirty adolescents with epilepsy and their caregivers. The original English version of this instrument underwent a process of translation and cultural adaptation by a translator with knowledge of English and epilepsy. Subsequently, it was carried out the back-translation and the Portuguese version was compared to the original, analyzing discrepancies, thus obtaining the final version for the Brazilian population. RESULTS: Participants were able to answer the questions. In four questions there was an association between the teenagers' educational level and the response pattern to the questionnaires. The authors found a strong positive correlation between the responses of adolescents and caregivers (RhoSpearman = 0.837; p < 0.001). The application of the questionnaire by the health team was feasible for all interviewed patients and their respective caregivers. CONCLUSION: The translation and application of the "Readiness Checklists" is feasible in Portuguese. Patients with lower educational levels felt less prepared for the transition than patients with higher educational levels, independently of age. Adolescents and caregivers showed similar perceptions regarding patients' abilities. The lists can be very useful tools to assess and plan the follow-up of the population of patients with epilepsy in the process of transition.

Genetic polymorphisms of the serotonin transporter are not related with depression in temporal lobe epilepsy caused by hippocampal sclerosis.

BACKGROUND: Mood disorders are the most frequent psychiatric disorders in patients with temporal lobe epilepsy caused by hippocampal sclerosis (TLE-HS). The pathophysiological mechanisms in common between TLE and mood disorders include abnormalities in the serotonergic pathway. We aimed to evaluate the association between serotonin transporter genetic polymorphisms - 5-HTTLPR and 5-HTTVNTR - and the presence of mood disorders in patients with TLE-HS. METHODS: We evaluated 119 patients with TLE-HS, with and without psychiatric disorder; 146 patients diagnosed with major depressive disorder (MDD), and 113 healthy volunteers. Individuals were genotyped for the 5-HTTLPR and 5-HTTVNTR polymorphisms. RESULTS: No difference was observed between the TLE-HS groups, healthy controls, and MDD without epilepsy. There was a correlation between the 12-allele of the 5-HTTVNTR and the family history of patients with epilepsy with TLE-HS (p = 0.013). CONCLUSIONS: In this study conducted in two Brazilian centers, the serotonin transporter polymorphisms evaluated cannot be associated with depressive disorder in patients with TLE-HS. Still, they do have some influence over some clinical characteristics of epilepsy in TLE-HS. These data may not be reproduced in other populations with distinct ethnic characteristics.

Seizure control and anxiety: Which factor plays a major role in social adjustment in patients with Juvenile Myoclonic Epilepsy?

PURPOSE: This study aimed to determine the presence of anxiety disorder and severity of anxiety symptoms in an extensive series of consecutive patients with JME and its association with epilepsy-related factors. In addition, we evaluated the impact of anxiety and clinical variables on social adjustment. METHODS: We prospectively evaluated 112 (56.2 % females, mean age 27.2 years) patients with an electroclinical diagnosis of JME and 61 (52.4 % females, mean age 29.3 years) healthy controls. Anxiety symptoms were assessed by the State and Trait Anxiety Inventory (STAI). Social functioning was addressed with Self-Report Social Adjustment Scale (SAS). The patient group was also evaluated with a psychiatric interview. RESULTS: Patients with JME presented more severe anxiety symptoms and worse social adjustment compared with controls. The presence of anxiety disorder and the severity of anxiety symptoms was associated with frequent seizures - generalized tonic-clonic seizures (p = 0.008) and drug-resistant epilepsy (p = 0.021). Regarding social adjustment, the severity of anxiety symptoms was associated with lower economic adjustment (p = 0.039), while the presence of anxiety disorder impacted family relationships (p 0.025). The presence of hard-to-control myoclonic seizure was associated with lower scores on work (p = 0.019), leisure activities (p = 0.008), family relationship (p = 0.022) and overall social adjustment (p = 0.038). CONCLUSION: Patients with JME have severe anxiety symptoms and worse social adjustment. Anxiety disorder and symptoms were associated with frequent seizures and drug-resistant epilepsy. Epilepsy-related factors and anxiety impaired distinct aspects of social functioning.

Dissociation between decision making under ambiguity and risk in patients with juvenile myoclonic epilepsy.

INTRODUCTION: Decision making (DM) is one aspect of impulsivity that can be defined by the ability to decide between two or more options in a given situation. To date, there are at least two types of DM that differ in the level of uncertainty, and how much information about consequences is provided. In this study, we aimed to evaluate the two domains of DM - under risk and ambiguous - with a comprehensive evaluation in a group of patients with juvenile myoclonic epilepsy (JME), and correlate with patients' characteristics, clinical variables, and neuropsychological evaluation for executive functions. METHODS: We evaluated 35 patients with JME and 39 healthy controls using the Iowa Gambling Task for DM under ambiguity and the Game Dice Task for DM under risk. We assessed the performance in Iowa Gambling Task and Game Dice Task through net scores, safe and risky choices, besides the type of decisions across time. RESULTS: Patients with JME had a higher number of risky choices compared to controls in the Game Dice Task. There was no significant difference between patients and controls in the Iowa Gambling Task. However, patients with higher seizure frequency had worse scores on decks C and D (safe choices) from the Iowa Gambling Task. CONCLUSION: Patients with JME have worse performance on DM under risk. The same was not observed for DM under ambiguity. Epilepsy-related factors and the presence of psychiatric disorders, but not executive dysfunction, were associated with a lower tendency for safe choices. These findings showed a dissociation between DM processes in patients with JME and a tendency to make disadvantageous decisions with measurable risks.

Association between the Occurrence of Primary Hypothyroidism and the Exposure of the Population Near to Industrial Pollutants in São Paulo State, Brazil.

BACKGROUND: Environmental agents interfere with thyroid function at multiple levels. This study was to investigate the association between pollutant concentrations and the primary hypothyroidism (PH) occurrence odds in residents living in the Capuava Petrochemical Complex (CPC) influence area. METHODS: This area was evaluated with the combination of the AERMOD dispersion model with the Weather Research Forecast (WRF) meteorological model (2016). The concentration of atmospheric pollutants were analyzed in 2017 using meteorological data on the period from 2005 to 2009, correlating this data with the research done in 2003 to 2005. A home-based questionnaire was applied to evaluate 2004 residents, of both sexes, aged from 8 to 72 years, based on their proximity to the industrial areas; were select residents with PH. RESULTS: Volatile organic compounds (VOCs), carbon monoxide (CO), and nitrogen dioxide (NO2) concentrations presented the highest correlations between the PH odds and pollutant concentrations. CONCLUSION: Air pollution associated with the presence of the CPC is an important environmental factor contributing to the development of PH in the nearby population. As the first study showing this association in Brazil, research should be continued to better understand the mechanisms and to find ways to compensate for or remedy to avoid health impacts in future populations.

Adult-onset psychogenic nonepileptic seizures: A multicenter international study.

PURPOSE: The aim of this multicenter international cross-cultural study was to compare clinical variables in a large sample of people with adult-onset psychogenic nonepileptic seizures (PNES). METHODS: In this retrospective study, we evaluated persons with documented PNES, who were older than 16 years of age at the onset, from four countries (i.e., Iran, Brazil, Venezuela, and Argentina) regarding their age, gender, PNES semiology, and possible predisposing factors. RESULTS: We included 389 patients (244 from Iran, 66 from Brazil, 51 from Venezuela, and 28 from Argentina). Age at diagnosis was 32 ±â€¯9 years (range: 17-64 years), and age at the onset of seizures was 27 ±â€¯8 years (range: 17-49 years). There was a female predominance in all countries. The demographic characteristics and factors associated with PNES were similar among the countries. However, there were significant semiological differences among the countries. CONCLUSION: This study corroborates the notion that PNES share more similarities than differences cross-culturally and across international borders. However, the background determined by cultural, ethnic, and religious differences may influence the semiology of PNES. Further cross-cultural studies involving more than two continents may advance our understanding of PNES.

Pediatric-onset psychogenic nonepileptic seizures: A retrospective international multicenter study.

PURPOSE: We compared various clinical characteristics of pediatric-onset psychogenic nonepileptic seizures (PNES) between patients from five countries. The purpose of this study was to advance our understanding of pediatric-onset PNES cross-culturally. METHODS: In this retrospective study, we compared consecutive patients with PNES with an age at onset of 16 years and younger from epilepsy monitoring units in Iran, Brazil, the USA, Canada, and Venezuela. Age, gender, age at seizure onset, seizure semiology, predisposing factors, and video-EEG recordings of all patients were extracted. Pearson Chi-Square, one-way ANOVA and Bonferroni correction tests were used for statistical analyses. RESULTS: Two hundred twenty-nine patients were studied (83 from Iran, 50 from Brazil, 39 from Canada, 30 from the USA, and 27 from Venezuela). Mean age at the onset of seizures was 12.1 ±â€¯3.2 years (range: 4-16 years). The sex ratio of the patients was 1.83: 1 (148 females and 81 males). Clinical characteristics of pediatric-onset PNES showed some significant differences among the nations. However, factors associated with pediatric-onset PNES in these five nations were similar. CONCLUSION: This study underscores how international cross-cultural studies can make important contributions to our understanding of PNES. Patients with pediatric-onset PNES from different countries were similar on many risk factors associated with PNES. This suggests universality in many features of PNES. However, intriguing differences were also noted with regard to seizure semiology, which might be the result of cultural factors.

BDNF Val66Met polymorphism is not related with temporal lobe epilepsy caused by hippocampal sclerosis in Brazilian population.

PURPOSE: Some variants of the brain derived neurotrophic factors (BDNF) gene, namely the Val66Met (rs6265), may contribute the risk for epilepsy development. We aimed to investigate if this polymorphism was associated with the risk for epilepsy development in TLE-HS and its correlation with epilepsy-related factors and the presence of psychiatric disorders. METHODS: We assessed 119 patients with unequivocal TLE-HS and 112 healthy controls. Individuals were genotyped for the polymorphisms of the gene encoding BDNF Val66Met. RESULTS: There was no difference between TLE-HS and healthy controls, for the genotypic distribution (p = 0.636) and allelic distribution (p = 0.471). There was no correlation between Val66Met and epilepsy-related factors and for psychiatric comorbidities (p = 0.888). CONCLUSIONS: Our findings demonstrated that polymorphism Val66Met is not associated with TLE-HS, epilepsy-related factors and psychiatric comorbidities in this selected group of patients.

Semiology of psychogenic nonepileptic seizures: An international cross-cultural study.

PURPOSE: We compared the semiology of psychogenic nonepileptic seizures (PNES) between patients from the USA and Brazil. This international cross-cultural comparative study may expand understanding of PNES across the borders. METHODS: We retrospectively investigated all patients with PNES admitted to one epilepsy center in the USA and one in Brazil. We classified their seizures into four classes: generalized motor, akinetic, focal motor, and subjective symptoms. All patients were interviewed by an epileptologist in both countries and were administered psychological assessment measures, including questions about PNES risk factors. For the statistical analyses, we compared patients from the two nations. RESULTS: Eighty-nine patients (49 from the USA and 40 from Brazil) were studied. Patients from the two countries were not significantly different with regard to sex and age, but patients from Brazil had earlier age at onset (26years vs. 34years; P=0.004) and a significantly greater delay in diagnosis (9.9years vs. 5.6years; P=0.001). Some characteristics of PNES were different between the two groups; patients from the USA had generally more seizure types and more often reported subjective seizures (55% in the USA vs. 10% in Brazil; P=0.0001). Clinical and historical characteristics of the patients were not significantly different. CONCLUSION: Delay in diagnosis of PNES may represent a major factor in resource-limited countries. Large multicenter cross-cultural studies may reveal subtle but significant cross-cultural differences with respect to the semiological, clinical, and historical aspects of PNES; however, patients with PNES share more similarities than differences.

The approach to patients with psychogenic nonepileptic seizures in epilepsy surgery centers regarding diagnosis, treatment, and education.

Previous studies, using surveys, provided an understanding about how health-care providers address patients with PNES. To date, there is limited information on the management of patients with PNES by tertiary referral centers for epilepsy. In this study, we surveyed 11 Brazilian epilepsy center directors about diagnosis, treatment, education and research on PNES. Respondents reported that patients with PNES represented 10-20% of all adult patients recorded by video-EEG (VEEG). All respondents recognized VEEG as the method to confirm the diagnosis, and 81.8% used this approach for confirmation. Most centers had a standard protocol for diagnosis. None of the centers had a particular protocol to treat PNES, but 90.9% had a uniform treatment approach including therapy and educational measures. Psychotherapy was not easily obtained in nine centers (81.8%). Seven (63.3%) centers reported ongoing research projects with PNES. Five centers referred to an educational PNES program discussing diagnosis, but only one reported an educational program for treatment. This study showed a commitment to PNES diagnosis; however, some gaps remain regarding treatment and training, namely implementing a psychotherapy approach for patients and providing educational curricula for clinicians.

Psychogenic nonepileptic seizures: should we use response to AEDS as a red flag for the diagnosis?

PURPOSE: Lack of response to anti-epileptic drugs (AEDS) is considered a "red flag" pointing to a diagnosis of Psychogenic Nonepileptic Seizures (PNES). On the other hand, placebo effects are relevant in any medical condition with a complex psychosocial component. We aimed to evaluate the presence and frequency of a placebo response in patients with sole PNES and explore its impact on diagnostic delay. METHODS: We reviewed the medical records of 102 patients referred for video EEG monitoring and diagnosed with PNES. Patients with PNES and epilepsy were excluded. The response to AEDs was analyzed according to patients' reports and medical records. Patients were classified, according to the response to AEDs, in two groups: responders (patients achieving remission) and non-responders. Then, we compared the diagnostic delay from the first event to the final diagnosis between these groups. RESULTS: Forty-seven patients (79.7%) with sole PNES who were using AEDs were identified. Twenty-two patients (46.8%) had reported complete or partial remission of PNES with mean response duration of 7.2 months (SD+9.6 months). The time delay of the diagnosis in the AED responder group was 10.6 years; the delay in non-responders was 5.6 years (p=0.035). CONCLUSION: Patients with sole PNES receiving AEDs can go into PNES remission. A favorable response to AEDs is likely to be interpreted as supporting a diagnosis of epilepsy and is associated with diagnostic delay. Physicians should bear in mind that patients with PNES may be particularly vulnerable to placebo effects.

Semiology of psychogenic nonepileptic seizures: age-related differences.

The few studies addressing semiology of psychogenic nonepileptic seizures (PNES) in children showed that this group differs from adults, considering the classical signs described. Our study with systematic assessment provides a direct comparison of the classical signs of psychogenic nonepileptic seizures (PNESs) in children and adults in order to establish the usefulness of the most important signs described for adults in children. Video-EEG recordings of patients with PNESs from 2006 to 2011 were analyzed. Twenty-five signs were selected as the most prevalent in literature, and their presence was evaluated. Events were categorized as either of the following: catatonic, major motor, minor motor, and subjective (Griffith et al., 2007 [11]). One hundred and fifteen patients were included; 63.5% were adults, 73.2% were females, and 14.4% had epilepsy. Adults presented more ictal eye closure (p=0.006), convulsions lasting >2 min (p<0.001), postictal speech change (p=0.021), vocalization during the "tonic-clonic" phase (p=0.005), and pelvic thrust movement (p=0.035). Biting the tip or side of the tongue and opisthotonos were rare and only present in adults. As for the semiological categories, major motor activity was the main feature in adults, and minor motor activity was more prevalent among children (52.9% and 38.1%, respectively; p=0.01). Our data showed that research about the distinct ictal features of PNESs, such as minor motor events that are more typical in children, is likely to be useful in promoting earlier recognition of PNESs in this population.

Pancreatic insufficiency in HIV: is it possible?

Pancreatic involvement in AIDS is very important and common, but there are few studies in the literature concerning the pancreas in AIDS. Therefore, our research involves an important issue in the pancreatic field. The objective of the study was to evaluate the profile of HIV-infected patients with probable exocrine pancreatic insufficiency and its relation to the degree of human immunodeficiency virus (HIV) infection. This is a cross-sectional study carried out at Faculdade de Medicina do ABC in partnership with the basic health care unit Vila Guiomar in Santo André. We selected 118 individuals divided into four groups (a control group and three other groups composed of AIDS patients, separated according to CD4 levels); participants had an interview, completed a questionnaire, and had laboratory and imaging tests. The only clinical variables with significant differences among the studied groups were the use of highly active antiretroviral therapy (HAART), the incidence of opportunistic infections, the administration of chemoprophylaxis, and weight loss. There were no differences in the amylase, lipase, and steatocrit dosages among the groups. Levels of fecal elastase 1 were lower in the HIV patient groups (2, 3, and 4) when compared with the control group, although all of them showed average levels that were much higher than the cutoff point (200 µg/g). Only nonalcoholic individuals showed a relationship between diarrhea and alterations in elastase levels. A relationship between the use of HAART and exocrine pancreatic insufficiency in different phases of HIV infection could not be verified.

Psychogenic non-epileptic seizures at a tertiary care center in Brazil.

Although psychogenic non-epileptic seizures (PNES) are a worldwide phenomenon, most of our knowledge addressing clinical characteristics is based on studies conducted in the USA, Europe, and Australia. There are scarce data about PNES in South American countries. This study provided a detailed analysis of the demographic, clinical, and psychosocial characteristics of 102 Brazilian patients with PNES. Seventy-eight patients (76.4%) were female with mean age of 35.27 years. Mean age at onset was 27.85 years; mean time to diagnosis was 7.89 years; 87.25% lived with their families; 56.89% were single; and only 33 (39.75%) worked on a regular basis. Depression was diagnosed in 48.03%. Thirty-three patients misdiagnosed as having epilepsy were using antiepileptic drugs. Stress factors were identified in 57.84%. This is the first Brazilian study that involves a large sample of patients with video-EEG-documented PNES and corroborates the idea that PNES are a worldwide phenomenon sharing several similarities, despite cultural and socioeconomic differences.

Validation of fecal elastase-1 determination using immunoenzymatic assay in HIV-infected patients.

Pancreatic elastase-1 is a proteolytic enzyme exclusively produced in the pancreas, is stable when passing through the bowel, and its determination is associated with chronic pancreatitis. The clinical diagnosis of pancreatitis is based on anamnesis, physical examination, radiological, sonographic, endoscopic, and laboratory findings. Nowadays, there is a test for the determination of fecal elastase-1, by enzymatic reaction (enzyme-linked immunosorbent assay, ELISA), which specifically determines human elastase-1, promoting the pancreatic function evaluation. Parameters such as linearity, calibration curve, sensitivity, specificity, precision, accuracy, recovery, and receiver operator characteristic (ROC) curve are used to evaluate the test. The aim of this study was the validation of the immunoenzymatic assay (ELISA) and the use of its results in patients with HIV, alcoholics, and under antiretroviral therapy. The study involved 157 patients, 95 of them were HIV-infected, and 62 were completely healthy. The elastase-1 ELISA kit from Bioserv was used, and we noted that the obtained results were linear, sensitive, precise, and accurate. Moreover, our results suggest that this test can be a laboratory evaluation to determine the relationship of pancreatitis with alcohol use, but not its association with antiretroviral use in HIV patients (P=0.424). This test is useful to diagnose pathologies related to pancreatic insufficiency.
