Electrodiagnostic methods to verify Guillain-Barré syndrome subtypes in Istanbul: A prospective multicenter study.

BACKGROUND AND AIMS: This study aimed to identify the clinical characteristics and electrodiagnostic subtypes of Guillain-Barré syndrome (GBS) in Istanbul. METHODS: Patients with GBS were prospectively recruited between April 2019 and March 2022 and two electrodiagnostic examinations were performed on each patient. The criteria of Ho et al., Hadden et al., Rajabally et al., and Uncini et al. were compared for the differentiation of demyelinating and axonal subtypes, and their relations with anti-ganglioside antibodies were analyzed. RESULTS: One hundred seventy-seven patients were included, 69 before the coronavirus disease 2019 pandemic (April 2019-February 2020) and 108 during the pandemic (March 2020-March 2022), without substantial changes in monthly frequencies. As compared with the criteria of Uncini et al., demyelinating GBS subtype diagnosis was more frequent according to the Ho et al. and Hadden et al. criteria (95/162, 58.6% vs. 110/174, 63.2% and 121/174, 69.5%, respectively), and less frequent according to Rajabally et al.'s criteria (76/174, 43.7%). Fourteen patients' diagnoses made using Rajabally et al.'s criteria were shifted to the other subtype with the second electrodiagnostic examination. Of the 106 analyzed patients, 22 had immunoglobulin G anti-ganglioside antibodies (14 with the axonal subtype). They had less frequent sensory symptoms (54.5% vs. 83.1%, p = 0.009), a more frequent history of previous gastroenteritis (54.5% vs. 22.9%, p = 0.007), and a more severe disease as compared with those without antibodies. INTERPRETATION: Serial electrodiagnostic examinations are more helpful for accurate subtype diagnosis of GBS because of the dynamic pathophysiology of the disease. We observed no significant increase in GBS frequency during the pandemic in this metropolis.

Birth outcomes in pregnant women with epilepsy: A Nationwide multicenter study from Türkiye.

OBJECTIVE: The present study was aimed at investigating the effects of anti-seizure medications (ASMs), patient demographic characteristics, and the seizure type and frequency on the development of congenital malformations (CMs) in the infants of pregnant women with epilepsy (PWWE). METHODS: PWWE followed up at the neurology outpatient clinic of 21 centers between 2014 and 2019 were included in this prospective study. The follow-up of PWWE was conducted using structured, general pregnant follow-up forms prepared by the Pregnancy and Epilepsy Study Committee. The newborns were examined by a neonatologist after delivery and at 1 and 3 months postpartum. RESULTS: Of the infants of 759 PWWE, 7.2% had CMs, with 5.6% having major CMs. Polytherapy, monotherapy, and no medications were received by 168 (22.1%), 548 (72.2 %), and 43 (5.7 %) patients, respectively. CMs were detected at an incidence of 2.3% in infants of PWWE who did not receive medication, 5.7% in infants of PWWE who received monotherapy, and 13.7% in infants of PWWE who received polytherapy. The risk of malformation was 2.31-fold (95% confidence interval (CI): 1.48-4.61, p < .001) higher in infants of PWWE who received polytherapy. Levetiracetam was the most frequently used seizure medication as monotherapy, with the highest incidence of CMs occurring with valproic acid (VPA) use (8.5%) and the lowest with lamotrigine use (2.1%). The incidence of CMs was 5% at a carbamazepine dose <700 mg, 10% at a carbamazepine dose ≥700 mg, 5.5% at a VPA dose <750 mg, and 14.8% at a VPA dose ≥750 mg. Thus the risk of malformation increased 2.33 times (p = .041) in infants of PWWE receiving high-dose ASMs. SIGNIFICANCE: Birth outcomes of PWWE receiving and not receiving ASMs were evaluated. The risk of CMs occurrence was higher, particularly in infants of PWWE using VPA and receiving polytherapy. The incidence of CMs was found to be lower in infants of PWWE receiving lamotrigine.

Metabolic syndrome and anthropometric indices in CTS hands: an electrophysiological study.

INTRODUCTION: This study aims to evaluate the effect of metabolic syndrome (MetS) and anthropometric indices on carpal tunnel syndrome (CTS). METHODS: Forty-three healthy controls and 41 CTS patients were enrolled. Complaints of patients were assessed by Boston Questionnaire (BQ). MetS components were investigated. Wrist circumference, wrist depth, wrist width, palm width, and palm length were measured. Routine nerve conduction studies of median and ulnar nerves as well as the "sensitive" comparison tests were performed. Cutaneous silent period (CuSP) was studied by stimulating both second and fifth digital nerves while recording over thenar muscles. RESULTS: The vast majority of the participants were female and right-handed. CTS was bilateral in 61% of patients. Data of 109 hands were analyzed. MetS was more frequent in CTS patients. BQ scores were not related to MetS. Waist circumference, serum TG, and fasting glucose levels were higher in CTS patients. CTS hands with MetS had lower median CMAP amplitudes and increased sensory thresholds. Sensory thresholds were increased with both median and ulnar nerve stimulations suggesting a wider spread of peripheral nerve excitability changes in MetS presence. CuSPs were recorded from all 109 hands. CuSP latencies and durations were similar between controls and CTS patients. Wrist ratio was the only anthropometric index that was a statistically significant predictor for CTS development. CONCLUSION: MetS was more prevalent in CTS patients. Some clinical and electrophysiological features (mainly sensory thresholds) may worsen in presence of MetS, but not the wrist ratio.

Autoimmune encephalitis and paraneoplastic syndromes in Turkey: a multi-centre study.

BACKGROUND: Autoimmune encephalitis (AIE) and paraneoplastic syndromes (PNS) are both rare groups of neurological diseases that are difficult to diagnose. AIM: We aimed to determine the common and distinct aspects of these two aetiologies of encephalitis as well as the characteristics of our patient group. METHODS: We respectively analysed the records of the patients including symptoms, demographic features, neurological examination, cranial-magnetic-resonance-imaging (MRI), electroencephalography (EEG) findings, cerebrospinal fluid results (CSF) findings. Autoimmune/paraneoplastic autoantibodies in blood and/or CSF were all documented. RESULTS: Forty-six patients fulfilled the diagnostic criteria. Thirty-eight of them were diagnosed with AIE, and 8 of them were diagnosed with PNS. The PNS group had higher nonconvulsive status epilepticus than the AIE (2/8 vs 0/38; p=0.027). PNS patients were diagnosed with a malignancy in their follow-ups more than those in the AIE group [4/38 vs 8/8] (p<0.001). When the symptoms of antibody-positive and negative patients were compared in the AIE group, the rates of consciousness/memory problems (13/15 vs 11/23; p=0.020) and speech impairment (8/15 vs 2/23; p=0.004) were significantly higher in patients without antibodies (n: 15) than in antibody-positive patients (n: 23). In antibody-negative groups, the rates of memory problems in neurological examination (13/15 vs 12/23 p=0.028) and temporal findings on electroencephalography were more prominent than antibody-positive groups (1/23 vs 5/15; p=0.027). The number of patients with cerebellar signs was higher in antibody-positive patients (6/23 vs 0/15; p=0.038). CONCLUSION: Although the positivity of autoantibodies is critical in the diagnosis of AIE and PNS, even minor differences in clinical and laboratory findings of patients are helpful in the diagnosis, especially in the autoantibody-negative patients. Comparing the data with other population studies has shown that several inherited and environmental factors may contribute to the pathophysiology of AIE and PNS, as well as clinical and laboratory differences.

The strategies for coping with stress of epilepsy patients.

OBJECTIVE: This study aims to compare the styles of coping with stress between patients with epilepsy and healthy individuals and to examine the effects of clinical features on methods of coping with stress. METHODS: The study enrolled 120 patients diagnosed with epilepsy. Forty healthy individuals were included as control group. Sociodemographic and clinical characteristics of the patients were recorded. The patients and controls completed the Coping Strategies with Stress Inventory (COPE), which comprises 60 items distributed into 15 scales. The COPE scores of the patients and controls were compared. RESULTS: Comparing the COPE scores of the patients and controls, the substance use score was higher in the controls. In terms of gender, seeking instrumental social support, active coping, seeking emotional social support, acceptance, and emotion-focused total coping scores were higher in women among patients. In terms of marital status, the positive reinterpretation and growth score of single patients was significantly higher than that of married patients. In patients with a history of febrile convulsions, the active coping, seeking emotional social support, and denial scores were higher. In terms of treatment, for the patients receiving polytherapy, the suppression of competing activities, focus on and venting of emotions, and dysfunctional total coping scores were higher than in patients receiving monotherapy. CONCLUSION: Epilepsy and stress are intertwined conditions. Epilepsy patients, confronted with stress, avoided using alcohol and substances compared to healthy individuals. There were differences among epilepsy patients according to gender, marital status, febrile convulsion history, number of medications, and approaches to coping with stress.

Metabolic syndrome and obstructive sleep apnea syndrome among patients with epilepsy on monotherapy.

OBJECTIVES: The study aimed to determine the frequency of metabolic syndrome (MetS) and obstructive sleep apnea syndrome (OSAS) in patients with epilepsy receiving monotherapy and the relationship between these syndromes and antiepileptic drugs (AEDs). METHODS: Two hundred and ninety-seven patients with epilepsy between the ages of 18-65 years receiving monotherapy for at least one year and 50 healthy participants were enrolled. Body mass indices and waist circumferences were measured. Serum fasting glucose levels, high-density lipoprotein (HDL), low density lipoprotein (LDL), total cholesterol (TC), triglyceride, and serum AED concentrations were noted. The frequency of MetS in patients with epilepsy was calculated. The snoring, tiredness, observed apnea, high blood pressure, body mass index, age, neck circumference, and male gender (STOP-Bang) questionnaire was used to determine the risk of OSAS. The relationship between these two syndromes and seizure type, disease duration, AED dosage, and treatment duration was analyzed. RESULTS: Metabolic syndrome was more frequent in patients with epilepsy compared with healthy participants (32.6% vs. 12.0%), and it was diagnosed in 37.8% of patients receiving valproic acid (VPA), 36.1% of patients receiving carbamazepine (CBZ), 34.9% of patients receiving oxcarbazepine (OXC), and 30.5% of patients on levetiracetam (LEV). There was a positive correlation between VPA treatment duration and MetS existence (p < 0.05). However, MetS frequency did not change because of seizure type, disease duration, or AED dosages in patients with epilepsy receiving monotherapy. The risk for OSAS was higher in patients with epilepsy compared with healthy participants (24.6% vs. 12%), and it was calculated high in 27.7% of patients receiving CBZ, 32.2% of patients receiving LEV, and 30.2% of patients receiving OXC. The OSAS risk was higher in patients who have focal seizures than generalized seizures (p = 0.044). There was no relationship between OSAS risk and duration of epilepsy, duration of treatment, drug doses, and serum drug levels (p > 0.05). CONCLUSION: Higher frequency of MetS and OSAS risk should be kept in mind on clinical follow-up of patients with epilepsy receiving monotherapy.

Do interictal EEG findings reflect cognitive function in juvenile myoclonic epilepsy?

PURPOSE: This study investigated the relationship between frontal lobe cognitive function and frontal focal electroencephalography (EEG) findings in patients with juvenile myoclonic epilepsy (JME). METHODS: The study enrolled 60 patients diagnosed with JME and followed at the Epilepsy Outpatient Clinic of the University of Health Sciences, Bakirkoy Psychiatric Hospital, and 30 healthy volunteers. Demographic and clinical features were recorded. Frontal lobe cognitive functions were tested in both groups. Video-EEG recordings of patients with JME were evaluated. The presence and duration of generalized discharges, the presence and lateralization of focal findings, and the presence of generalized discharges during hyperventilation and photic stimulation were recorded during EEG. Cognitive function test results were compared between the two groups, and the relationship between the EEG findings and cognitive function was investigated. RESULTS: The study included 35 (58.3%) female and 25 (41.6%) male patients and 17 (56.7%) female and 13 (43.3%) male healthy controls. The mean ages of the group with JME and controls were 28.3 ±â€¯8.6 (16-50) and 31.3 ±â€¯7.9 (17-45) years, respectively. Patients with JME performed more poorly on the frontal lobe cognitive tests than controls (p < 0.05). Patients whose generalized discharges were longer than 1 s performed more poorly on tests evaluating attention and made more perseverative errors (p < 0.05). There was no significant correlation between the presence of focal EEG findings and the scores on frontal lobe cognitive functions tests in the group with JME (p > 0.05). CONCLUSION: Frontal lobe cognitive functions are affected in patients with JME. The cognitive effects were more pronounced in patients with prolonged generalized discharges on EEG.

The inflammatory markers and prognosis of cervicocephalic artery dissection: a stroke center study from a tertiary hospital.

OBJECTIVE: Cervicocephalic artery dissection (CeAD) is the most common cause of ischemic stroke in young adults. Although the exact cause is unknown, inflammation is thought to have a role. Here, we investigated the relationship between CeAD and inflammation. METHODS: Patients diagnosed with CeAD in our stroke center were evaluated retrospectively, and their demographic and clinical features were recorded. The C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), white blood cell, neutrophil and lymphocyte counts, platelet/lymphocyte ratio (PLR), and neutrophil/lymphocyte ratio (NLR) were recorded on admission. Modified Rankin scores (mRS) were noted on admission and at 6 months to evaluate the dependency status and functional outcome of each patient. RESULTS: Of the 95 patients in the study, 70 (73.7%) were male, and the mean age was 44.4 ± 9.8 years. Patients with high WBC count, ESR, PLR, and NLR frequently had mRS scores of 3-6 at admission; these differences were significant (p = 0.04, p = 0.02, p = 0.04, and p = 0.02, respectively). At 6 months, patients with high CRP and ESR at admission also had significantly poorer prognoses (p < 0.001, p = 0.002, respectively). PLR and NLR values were higher in patients with mRS of 3-6. But there were no significant differences between the good and poor prognosis groups regarding PLR and NLR (p = 0.22, p = 0.05, respectively). CONCLUSION: Inflammation may have a role in the prognosis of CeAD, and inflammatory markers can be evaluated as auxiliary tests for determining prognosis.

Cognitive impairment and drug responsiveness in mesial temporal lobe epilepsy.

OBJECTIVES: Mesial temporal lobe epilepsy (MTLE) is the most common form of partial epilepsies. Seizures of MTLE with hippocampal sclerosis (MTLE-HS) are typically resistant to antiepileptic drug (AED) therapy. Although memory disturbances in patients with MTLE-HS are expected, verbal attention and frontal lobe functions may also be impaired. We aimed to examine the relationship between the clinical features and cognitive functions of patients by comparing cognitive test scores of patients with MTLE with few seizures (drug-responsive group) and those with frequent seizures (pharmacoresistant group). METHODS: Seventy-nine patients with MTLE-HS and 30 healthy controls were enrolled. Thirty-four patients were accepted as the drug-responsive group (DrG), and 45 patients were included in the pharmacoresistant group (PRG). Tests evaluating attention, memory, and executive functions were performed on all participants. RESULTS: Forty-nine (62%) female and 30 (38%) male patients with MTLE-HS, and 14 (46.7%) female and 16 (53.3%) male controls participated in the study. The mean age of the patients and controls was 33.53 ±â€¯9.60 (range, 18-57) years and 35.90 ±â€¯7.98 (range, 18-56) years, respectively. Both the DrG and PRG showed poorer performances in tests evaluating memory and frontal lobe functions when compared with the control group (CG). Additionally, attention test results were significantly worse in the PRG than in the DrG. CONCLUSION: It is reasonable to say that increased seizure frequency is the main causative factor of verbal attention deficit due to the poorer attention test results in the PRG. Poor performances in memory and frontal lobe function tests of all patients with MTLE-HS emphasized the importance of the mutual connection between the temporal lobe and prefrontal cortices.

Frontal lobe cognitive functions and electroencephalographic features in juvenile myoclonic epilepsy.

PURPOSE: The study aimed to examine the relationship between frontal lobe functions and interictal electroencephalography (EEG) discharge characteristics of patients with juvenile myoclonic epilepsy (JME). METHOD: Thirty patients with JME who had EEG with asymmetrical generalized discharge (aEEG), 15 patients with JME who had EEG with symmetrical generalized discharge (sEEG), and 15 healthy controls were included in the study. To evaluate attention, the digit span and Corsi block tests were used; to evaluate memory, we applied verbal and visual memory tests; to evaluate frontal lobe functions, we used clock drawing, verbal fluency, the Stroop test, trail making, mental control, and antisaccadic eye movement tests as well as the continuous performance (CPT) tests. ETHICAL CONSIDERATIONS: The research was approved by the Research Ethics Committee of the Bakirkoy Research and Training Hospital for Psychiatry, Neurology, Neurosurgery, with protocol number: 41340010/4891-262, date: 05.02.2013. RESULTS: The mean age of the 45 patients with JME was 22.89 ±â€¯6.77 years, and 34 (75.6%) were female. The age at onset of seizures and disease duration of the patients with JME was 15.56 ±â€¯4.06 years (range, 9-26 years) and 7.20 ±â€¯5.59 years (range, 1-25 years), respectively. All patients were under valproate (VPA) treatment, and the mean VPA dosage was 783.33 ±â€¯379.14 mg/day. Patients with JME scored worse than the control group in attention, memory, and frontal lobe functions. In patients with aEEG, scores of attention, memory, and frontal lobe function tests were lower than in patients with sEEG; however, with the exception of CPT, they were not statistically significant. CONCLUSION: Cognitive functions in JME have been shown to be impaired. Furthermore, we concluded that the frontal lobe cognitive functions may be worse in patients with aEEG than in patients with sEEG. Further studies in patients with JME with aEEG abnormalities may lead to a better understanding of the pathophysiology of JME.

Prevalence and clinical characteristics of headache in juvenile myoclonic epilepsy: experience from a tertiary epilepsy center.

The comorbidity of headache and epilepsy is often seen in neurological practice. The objective of this study was to assess the prevalence, types of, and risk factors for headache in juvenile myoclonic epilepsy (JME). We assessed a total of 200 patients and 100 healthy controls in our study. Headache was classified in participants using a self-administered questionnaire. Demographical, clinical features and headache characteristics were recorded. Seizure and headache temporal profiles were noted. Headache was present in 111 (56%) patients and 50 (50%) healthy participants. From these patients, 47 (42.3%) JME patients had migraine [30 (27%) migraine without aura (MO), 17 (15.3%) migraine with aura (MA)], 52 (46.8%) had tension type headache (TTH), 4 (3.6%) had both migraine and TTH, and 8 (7.2%) had other non-primary headaches. In the healthy control group, migraine was detected in 16 (32%) subjects, TTH in 33 (66%), both migraine and TTH in 1 (2%) subject. A positive migraine family history and symptom relief with sleep were more frequent in JME patients (p = 0.01). Headache was classified as inter-ictal in 82 (79.6%) patients and peri-ictal in 21 (20.4%) patients. In conclusion, the present study revealed that headache frequency was not significantly different between JME patients and healthy controls (p > 0.05). However, migraine frequency was higher in JME patients than healthy controls. Some migraine and TTH characteristics were different in between groups. We suggest that our results support both genetic relationship and shared underlying hypothetical pathopysiological mechanisms between JME and headache, especially migraine.

Profile of Syrian Asylum-Seekers from Neurological Clinic in a Tertiary Center.

BACKGROUND: The humanitarian response for Syria has been largely managed either from within Syria or from neighboring countries, particularly Turkey. This study was aimed at determining the sociodemographic and clinical profiles of Syrian asylum-seekers admitted to our clinic, changes in patient number across years, and the percentage of patients on follow-ups. METHODS: Syrian patients who were admitted to the neurology outpatient clinics, neurology emergency department (ED), and hospitalized in the neurology clinics were included in the study. Age, gender, number of admissions, year of admissions, chief complaints, diagnoses, and follow-up percentages of patients were recorded. RESULTS: The total number of Syrian patients who were first admitted to our hospital and consulted from other clinics, were found to be 763 (ED: 609 [79.8%], outpatient: 134 [17.6%] consultation: 20 [2.6%]). A total of 543 (96.1%) of the patients with a neurological disorder did not come to the follow-ups even though their conditions required regular follow-ups. The most common complaints were headache (24.2%), fainting (16.1%), weakness (11.9%), and dizziness (10%). CONCLUSION: Most of the patients admitted to our hospital did not come to the follow-ups and information regarding their treatments could not be obtained. Even though the Republic of Turkey provided the Syrian asylum-seekers with free medical care, utilization of these resources may be limited because of socioeconomic issues.

Caregiver burden and quality of life in early stages of idiopathic Parkinson's disease.

BACKGROUND AND PURPOSE: The aim of this study was to assess the impact of early stage of idiopathic Parkinson's disease (IPD) on caregiver burden with disease severity, duration, disability and psychiatric symptoms. METHODS: 30 IPD patient (15 female, 15 male) - caregiver (18 female, 12 male) pairs participated in the study. Hoehn and Yahr (H-Y) scale was used to provide the assessment of disease progression and Unified Parkinson's Disease Rating Scale (UPDRS) was used for assessing disability and impairment. Zarit Caregiver Burden Inventory (ZCBI) was used to ascertain the distress experienced by caregivers. Hospital Anxiety and Depression scale (HADS) was performed on both patient and caregiver groups to evaluate anxiety and depression. Depressive symptoms of both groups were also measured by Beck Depression Inventory (BDI). Patients' psychotic symptoms were assessed using the part 1- mentation, behavior and mood section of UPDRS. Mini-Mental State Examination (MMSE) was used to evaluate dementia symptoms and Short Form-36 (SF-36) was also used to assess quality of life. RESULTS: We found significant correlation between caregiver burden with disease severity and duration. There was a significant difference between high UPDRS scores and the caregiver's will for placing her/his patient in a long-term institution. Patients who had depression risk according to BDI had also high UPDRS scores. Patients with off period had higher UPDRS scores and lower SF-36 subdomains of general health, physical functioning, emotional role and social functioning. CONCLUSION: IPD is a chronic, progressive neuro- degenerative disease and comprises substantial burden on patients, families of patients and caregivers. The disease duration and disability have a remarkable impact on caregiver burden. For the good quality of caregiving, protective therapies should be recommended for caregivers if needed.

Evaluation of inner retinal layers with optic coherence tomography in vigabatrin-exposed patients.

In order to reveal the underlying retinal pathology leading to dysfunction in vigabatrin-exposed patients, we aimed to evaluate the inner retinal layers encompassing ganglion cell complex (GCC) layer and inner plexiform layer with new generation optic coherence tomography (OCT). Fourteen patients with epilepsy and exposure to vigabatrin and 12 clinically normal individuals, constituting the control group, were included. Retinal images were obtained using spectral-domain OCT (Optovue RTVue Fourier domain). Nasal and superior quadrants of retinal nerve fiber layer (RNFL) were found to be significantly lower in the patient group compared to the controls (p < 0.01). No significant difference was shown in the thickness of GCC layer (p > 0.05). Foveal thickness was significantly higher in the patient group (p: 0.006), but no significant difference was found in perifoveal and parafoveal regions between groups (p > 0.05). The thickness of RNFL was found to be lower in vigabatrin-exposed patients without any reduction in GCC layer in the macular region. However, foveal thickness was found to be significantly higher compared to perifoveal and parafoveal macular regions in vigabatrin-exposed patients. In conclusion, OCT revealed reduced thickness of RNFL without any reduction in ganglion cell layer in our study. The objective quantitative assessment of OCT is a practical noninvasive method and it can have role in future monitoring of these patients.

Knowledge of epilepsy among persons with epilepsy in Turkey.

PURPOSE: It has been shown in studies that there are knowledge gaps about epilepsy in both developing and developed countries all around the world. Lack of knowledge exists even among people with epilepsy (PWE), and this may affect their lives negatively. This study aimed to evaluate what PWE in Turkey know about their disease. METHOD: A self-completed questionnaire consisting of demographic details, an item about perceived stigmatization, and 24 items about general knowledge of medical and social aspects of epilepsy was developed. Applicants were asked to answer 'true', 'false', or 'do not know' to each statement. The scores of the questionnaire were defined as low (< 15 point), medium (≥ 15-20), and high (≥ 20). RESULTS: The mean score on the questionnaire was 15.17 ± 3.74 (range, 4-24). One hundred twenty-five PWE (37.9%) scored low, 170 PWE (51.5%) scored medium, and 35 PWE (10.6%) scored high. The education level and household income were highly correlated with the knowledge level. Higher education level (r: 0.31) and high income (r: 0.25) were correlated with higher mean scores (p < 0.01). Lack of information was present particularly in terms of etiology, management of seizures, and medication during pregnancy. CONCLUSION: We documented the knowledge deficit of PWE about their disease, a situation that may lead to suboptimal management and negative attitudes. We concluded that study programs should be organized and more education should be provided to PWE in order to overcome these issues.

A rare cause of cerebral venous thrombosis: cryptococcal meningoencephalitis.

Cryptococcal meningoencephalitis (CM) is a serious central nervous system infection caused by Cryptococcus neoformans, seen mostly in immunocompromised hosts and less in immunocompetent patients. The vast majority of cryptococcosis cases are seen as human immunodeficiency virus infections with advanced immunosuppression. Meningitis and meningoencephalitis are the most common clinical manifestations. Nevertheless, immunocompetent patients with CM are rarely reported. Cerebral venous sinus thrombosis is a rare complication of CM. Here, we report an immunocompetent patient with CM from a non-endemic area, who presented with an acute onset and atypical symptoms associated with cerebral venous thrombosis.

Stigmatization and social impacts of epilepsy in Turkey.

OBJECTIVE: Stigma associated with epilepsy has negative effects on psychosocial outcomes, affecting the lives of people with epilepsy (PWE). Obtaining basic social rights can be difficult compared to the general population. The aim of our study was to evaluate the perceived stigma among PWE and social attitude towards the disease and to compare the social measures with the general population in Turkey. METHOD: A self-completed questionnaire consisting of demographic details and items about attitudes and perceived stigmatization was developed. Participants consisted of patients with various types of seizures who were randomly chosen from the epilepsy outpatient clinic. They were requested to complete the questionnaire. RESULTS: Questionnaires were obtained from 330 PWE. One hundred forty individuals (43.3%) out of 323 reported feeling stigmatized. The marriage and total fertility rates were below the national rates of Turkey. Keeping their epilepsy as a secret from society was prevalent. Although the education rate was not below the national rate, unemployment rate was high, and the average monthly wage was significantly lower than that of the general population. The majority thought that their families were protective towards them. Only 2 of the 330 participants were living alone. CONCLUSION: The present study supports the perception of stigma associated with epilepsy and its negative impact on the lives of PWE in Turkey. Clearly, more research is needed to understand the reasons for stigma and how to decrease its impact.

EXTREME DELTA BRUSH EEG PATTERN IN A CASE WITH ANTI-NMDA RECEPTOR ENCEPHALITIS.

Anti-N-methyl-D-aspartate receptor NMDA-R encephalitis is caused by antibodies against the NMDA-R and characterized by a severe encephalopathy with psychosis, epileptic seizures and autonomic disturbances. This disorder is often accompanied with malignancies, especially ovarian teratoma. Some patients' EEGs show a different pattern similar to the waveforms of premature infants and this pattern is specifically named as extreme delta brush (EDB). We report a 24-year-old female having anti-NMDA receptor encephalitis and EDB patern.

THROMBOCYTOPENIA WITH GABAPENTIN USAGE.

Gabapentin is an antiepileptic drug approved for adjunctive therapy for partial seizures. We report a case of a patient who had thrombocytopenia with the dose of 2400 mg/day of gabapentin. The causal relationship between gabapentin and thrombocytopenia was revealed by dramatic increase in thrombocyte count following the cessation of the gabapentin treatment. To our knowledge, this is the first case report with a hematopoietic side effect of gabapentin.
