MRI findings in children with migraine or tension-type headache.

PURPOSE: Migraine and tension-type headache are common primary headaches in children. There is a risk of developing secondary headache in children. The current study was aimed to evaluate magnetic resonance imaging findings (MRI) in children with migraine or tension-type headache. METHODS: The study was planned in children with migraine or tension-type headaches who have been followed up in the pediatric neurology outpatient clinic with regular office visits for at least two years and had neuroimaging in the last year. RESULTS: 280 patients (187 female patients) datas were studied. 91 (61 female patients) were followed up with the diagnosis of migraine and 189 (126 female patients) with the diagnosis of tension-type headaches. The age of patients was found to be 13.1 ± 3.4 years. Brain tumor was found in one child with tension-type headache who had papilledema. Incidental MRI findings found 7.7% and 12.7% in migraine and tension-type headache, respectively. MRI findings in the study were arachnoid cyst (14), pituitary adenoma (6), mega cisterna magna (6), pineal cyst (3), non-specific gliosis (2) and tumor (1). CONCLUSION: Arachnoid cysts were found incidental as the most common MRI finding in children with migraine or tension-type headache. The rare life-threatening secondary headache may develop in children. The fundus examination as a complement to the neurological examination can be useful for requesting MRI.

Specificity and sensitivity of the SeLECT score in predicting late seizures in patients undergoing intravenous thrombolytic treatment and the effect of diabetes mellitus and leukoaraiosis.

BACKGROUND: Seizures after stroke can negatively affect the prognosis of ischemic stroke and cause a decrease in quality of life. The efficacy of intravenous (IV) recombinant tissue plasminogen activator (rt-PA) treatment in acute ischemic stroke has been demonstrated in many studies, and IV rt-PA treatment has been increasingly used around the world. The SeLECT score is a useful score for the prediction of late seizures after stroke and includes the severity of stroke (Se), large artery atherosclerosis (L), early seizure (E), cortical involvement (C), and the territory of the middle cerebral artery (T). However, the specificity and sensitivity of the SeLECT score have not been studied in acute ischemic stroke patients that received IV rt-PA treatment. OBJECTIVE: In the present study, we aimed to validate and develop the SeLECT score in acute ischemic stroke patients receiving IV rt-PA treatment. METHODS: The present study included 157 patients who received IV thrombolytic treatment in our third-stage hospital. The 1-year seizure rates of the patients were detected. SeLECT scores were calculated. RESULTS: In our study, we found that the SeLECT score had low sensitivity but high specificity for predicting the likelihood of late seizure after stroke in patients administered IV rt-PA therapy. In addition to the SeLECT score, we found that the specificity and sensitivity were higher when we evaluated diabetes mellitus (DM) and leukoaraiosis. CONCLUSION: We found that DM was an independent risk factor for late seizures after stroke in a patient group receiving thrombolytic therapy, and late seizures after stroke were less frequent in patients with leukoaraiosis.

ANTECEDENTES: As convulsões após o AVC podem afetar negativamente o prognóstico do AVC isquêmico e causar uma diminuição na qualidade de vida. A eficácia do tratamento com ativador do plasminogênio tecidual recombinante (rt-PA) intravenoso (IV) no AVC isquêmico agudo foi demonstrada em muitos estudos, e o tratamento com rt-PA IV tem sido cada vez mais usado em todo o mundo. A pontuação SeLECT é uma pontuação útil para a previsão de convulsões tardias após AVC e inclui a gravidade do AVC (Se), aterosclerose de grandes artérias (L), convulsão precoce (E), envolvimento cortical (C) e o território do meio artéria cerebral (T). No entanto, a especificidade e a sensibilidade do escore SeLECT não foram estudadas em pacientes com AVC isquêmico agudo que receberam tratamento IV com rt-PA. OBJETIVO: No presente estudo, objetivamos validar e desenvolver o escore SeLECT em pacientes com AVC isquêmico agudo recebendo tratamento IV com rt-PA. MéTODOS: O presente estudo incluiu 157 pacientes que receberam tratamento trombolítico IV em nosso hospital de terceiro estágio. As taxas de convulsão de 1 ano dos pacientes foram detectadas. Os escores SeLECT foram calculados. RESULTADOS: Em nosso estudo, descobrimos que o escore SeLECT apresentou baixa sensibilidade, mas alta especificidade para prever a probabilidade de convulsão tardia após AVC em pacientes que receberam terapia IV com rt-PA. Além do escore SeLECT, descobrimos que a especificidade e a sensibilidade foram maiores quando avaliamos diabetes mellitus (DM) e leucoaraiose. CONCLUSãO: Descobrimos que DM foi um fator de risco independente para convulsões tardias após AVC em um grupo de pacientes recebendo terapia trombolítica, e convulsões tardias após AVC foram menos frequentes em pacientes com leucoaraiose.

A clinical evaluation of gelastic and dacrystic seizures: a multicenter study.

BACKGROUND: Gelastic seizures are extremely rare, short-lasting, unprovoked, and uncontrollable laughing attacks. We conducted this retrospective evaluation to determine whether these symptoms, manifesting in different forms, such as cheerful laughter, laughing, smiling, and sobbing had any value in terms of etiology or localization. METHODS: A total of 31 patients who exhibited bouts of laughing or crying and who were under follow-up between 2000 and 2019 at tertiary epilepsy centers were included in the study. Laughing seizures were divided into three groups in terms of semiology (i.e., laughter with mirth, laughter without mirth, and smile). Dacrystic seizures were accompanied by some gelastic seizures and were divided into two groups in terms of semiology (i.e., weeping loudly [motor and voice-sobbing] and crying). RESULTS: Of the 27 patients with laughing seizures, 12 had seizures that manifested with smiling, 7 had seizures that manifested with laughing and mirth, and 8 had seizures that manifested with laughter without mirth. Dacrystic-gelastic seizures were observed in four patients, among whom 2 patients had crying and laughter without mirth and 2 patients had weeping loudly and laughter without mirth episodes. CONCLUSION: Gelastic and dacrystic seizures often suggest hypothalamic hamartomas, in the literature. This rare ictal behavior can originate from different cortical locations and lesions of a different nature. However, we found that gelastic seizures with smiling were a more homogenous group with regard to location in the temporal lobe, which we aimed to show by evaluating the patients included in this study.

ANTECEDENTES: Crises gelásticas são ataques de riso extremamente raros, de curta duração, não provocados e incontroláveis. Realizamos esta avaliação retrospectiva para determinar se esses sintomas, manifestando-se de diferentes formas, como riso alegre, riso, sorriso e soluço, tinham algum valor em termos de etiologia ou localização. MéTODOS: Foram incluídos no estudo 31 pacientes que apresentavam crises de riso ou choro e que estavam em acompanhamento entre 2000 e 2019 em centros terciários de epilepsia. As crises de riso foram divididas em três grupos em termos de semiologia (ou seja, riso com alegria, riso sem alegria e sorriso). As crises dacrísticas foram acompanhadas por algumas crises gelásticas e foram divididas em dois grupos em termos de semiologia (ou seja, choro alto [motor e soluçar a voz] e choro). RESULTADOS: Dos 27 pacientes com crises de riso, 12 tiveram crises que se manifestaram com sorriso, 7 tiveram crises que se manifestaram com riso e alegria e 8 tiveram crises que se manifestaram com riso sem alegria. Crises dácristico-gelásticas foram observadas em quatro pacientes, sendo 2 pacientes com choro e riso sem alegria e 2 pacientes com choro alto e riso sem alegria. CONCLUSãO: Crises gelásticas e dacrísticas frequentemente sugerem hamartomas hipotalâmicos, na literatura. Este comportamento ictal raro pode ter origem em diferentes localizações corticais e lesões de natureza diversa. No entanto, verificamos que as crises gelásticas com sorriso foram um grupo mais homogêneo quanto à localização no lobo temporal, o que buscamos evidenciar avaliando os pacientes incluídos neste estudo.

The Efficacy and Safety of Lumbar Accessed Catheter-Assisted Epidural Blood Patch in Cervical and Thoracic Cerebrospinal Fluid Leakage.

OBJECTIVE: To evaluate the clinical and radiological results of lumbar accessed catheter-assisted epidural blood patch (LACA-EBP) technique in treatment of spontaneous intracranial hypotension secondary to cervicothoracic cerebrospinal fluid leakage. METHODS: Patients presenting with spontaneous intracranial hypotension where magnetic resonance imaging cisternography confirmed and localized the cerebrospinal fluid leakage at cervicothoracic levels were treated with LACA-EBP. Visual analog scale (VAS) score for headache at baseline, third day after treatment, and during long-term follow-up was used to assess the treatment response. Posttreatment VAS score ≤3 on the third day defined treatment success, and VAS score ≥4 indicated treatment failure. RESULTS: LACA-EBP was performed in 10 patients (7 females, 3 males) with a mean age of 38.4 ± 10.5 years. Orthostatic headache was the most common presenting symptom (10/10; 100%) followed by nausea (5/10; 50%). Pituitary gland enlargement was the most commonly observed finding on pretreatment cranial magnetic resonance imaging (9/10; 90%). On magnetic resonance imaging cisternography, 8 patients had cervical and/or thoracic fistulas, whereas 2 patients had multiple-level fistulas. LACA-EBP was successful in all patients with no complications. All patients showed a treatment response with a 72-hour VAS score ≤3. Follow-up VAS scores were available for 8 patients with a clinical follow-up duration of 1-74 months (median 7.5 months). During clinical follow-up, headache recurred in 2 patients. CONCLUSIONS: In our study cohort, LACA-EBP was a safe and efficacious technique in treatment of cerebrospinal fluid leakage at cervical and thoracic levels.

The REM-sleep-related characteristics of narcolepsy: a nation-wide multicenter study in Turkey, the REMCON study.

INTRODUCTION: Narcolepsy type 1 (NT1) is caused by hypocretin deficiency, the pathophysiology of narcolepsy type 2 (NT2) has not been delineated. Except for the hypocretin deficiency and cataplexy, all clinical and laboratory features used in the diagnosis of NT2 are identical to those used for NT1. The aim of this study was to assess the rapid eye movement (REM) sleep-related characteristics in the patients with narcolepsy; the characteristics of REM sleep in polysomnography (PSG) and multiple sleep latency test (MSLT) recordings, the quantification of REM sleep without atonia (RSWA) and atonia index, and the analysis of rapid eye movements (REMs) during REM sleep. MATERIALS AND METHODS: This study was planned by the Sleep Medicine Study Group of the Turkish Neurology Society, and conducted in 11 centers in eight cities in Turkey. The analysis of RSWA was analyzed by reviewing all REM sleep periods on nocturnal PSG and MSLT recordings per standard criteria. The total duration of the increased muscle tone during REM sleep in the chin and bilateral leg electromyography (EMG) recordings was calculated as RSWA index. The REMs index was also investigated the relation to the RSWA. RESULTS: A total of 274 patients were involved; 147 patients (53.6%) were males and 127 patients (46.4%) were females; the mean age was 29.1 ± 12.0 years. The diagnosis of NT1 was made in 166 patients (60.6%), and 108 patients (39.4%) were diagnosed as having NT2. The mean Epworth sleepiness scale score was significantly higher in patients with NT1 than the patients with NT2 (P = 0.001). The diagnosis of REM sleep behavior disorder (RBD) was made in 19.3% of the patients with NT1 versus in 2.8% of the patients with NT2 (P < 0.001). The percentage of SOREMP in PSG recordings was significantly higher in patients with NT1 (37.1%) than those with NT2 (18.9%, P = 0.001). MSLT showed that the mean sleep latency was shorter in patients with NT1 compared to those with NT2 (P < 0.001). The total duration of REMs on electrooculography recordings was also significantly higher in patients with RSWA in comparison with the patients without RSWA (P = 0.002). Total duration of REMs was significantly and positively correlated with the duration of RSWA on chin-EMG and leg-EMG recordings (P = 0.001). ROC analyses showed an RSWA index of ≥2% for the RSWA on chin-EMG with a sensitivity of 86.7% and a specificity of 71.3% (P < 0.001). The REMs index ≥20% was associated with the presence of RSWA with a sensitivity of 70.0% and a specificity of 57.1% (P = 0.008). CONCLUSIONS: In this nation-wide study, we identified for the first time that the increase in REMs density during REM sleep may be a major correlate of the RSWA. Significant positive correlations were demonstrated between the total duration of REMs on electrooculography recordings and the mean durations of RSWA in both chin and leg EMG recordings. A REMs index of >20% was demonstrated to have a moderate sensitivity and specificity in the diagnosis of RSWA. As observed in chin RSWA index, REMs index also showed a significantly high association with RBD, in comparison to RSWA per standard criteria.

Effects of quarantine applied during the COVID-19 pandemic on mental health and quality of life in patients with multiple sclerosis and healthy controls.

BACKGROUND: The coronavirus outbreak, which emerged in Wuhan, China, in late 2019 and spread to the world, has changed each of our lives. OBJECTIVE: To investigate the effects of quarantine on depression, anxiety, sleep quality, fatigue, and SF-36 of multiple sclerosis (MS) patients during the COVID-19 outbreak and differences between healthy controls (HC). METHODS: Eighty-six MS patients and 65 HC patients were included in the study. Participants filled out the various scales through face-to-face interviews for mental health assessment from January 15 to February 15, 2021. RESULTS: When both groups were compared in terms of BECK-D inventory (p < 0.001), BECK-A inventory (p = 0.010), and FS (p < 0.001), the patient group had significantly higher results. Physical functioning (p < 0.001), physical role limitation (p = 0.001), energy vitality rates (p = 0.010), and general health perception (p < 0.001) were higher in the HC group. When MS patients were divided according to EDSS scores, BECK-A (p < 0.001), BECK-D (p = 0.001), and PSQI (p = 0.006) scores of the patients with EDSS > 3 were higher, while emotional role restriction rates (p = 0.006), energy and vitality (p = 0.018), and pain (p = 0.005) were significantly lower than those with EDSS ≤ 3. When MS patients were divided into two groups as who had COVID-19 and who did not and compared SF-36 subscale scores, pain, (p = 0.049) and mental status (p = 0.030) were obtained significant differences in the two groups. CONCLUSIONS: Our study revealed that MS patients, who are more susceptible to the new 'normal' that emerged during the pandemic period, are among the priority groups that should be supported in terms of mental health as well as physical health.

The evaluation of psychogenic non-epileptic seizures (PNES) cases with saline injection method in video-EEG monitorization unit.

BACKGROUND: It has been reported that 10 to 30% of patients sent to epilepsy centers with a diagnosis of refractory epilepsy are diagnosed with psychogenic non-epileptic seizure (PNES). A wide variety of provocative methods are used to assist PNES diagnosis. OBJECTIVE: To investigate the effect of seizure induction on the diagnosis and prognosis of PNES. METHODS: We retrospectively examined 91 patients with PNES complaints in our video-EEG laboratory. Intravenous saline was administered to all patients for induction of seizures. RESULTS: Saline injection was performed in 91 patients referred to our EEG lab with PNES initial diagnosis, 57 of whom were female and 34 male. Saline injection triggered an attack in 82 patients (90%). CONCLUSIONS: In this study we have concluded that provocative methods are practical, cheap and, most of all, effective for patient diagnosis. In clinical practice, explaining the diagnosis is the first and most important step of the treatment, and careful patient-doctor communication has a positive impact on patient prognosis.

Investigation of chronic venous insufficiency in patients with sleep disorders due to restless legs syndrome.

BACKGROUND: We aimed to investigate of chronic venous insufficiency on patients with sleep disorder due to restless legs syndrome. METHOD: Five hundred forty-one cases on whom polysomnography was performed due to sleep disorder were evaluated retrospectively. Forty patients with restless legs syndrome were determined. They were examined by history, physical examination, and duplex ultrasonography in terms of chronic venous insufficiency. The sleep stage rates of both groups were compared (that the rate of total sleep time in polysomnography to sleep stages is expressed as minute and percentage has been defined as sleep stage rate). RESULT: Chronic venous insufficiency was identified in 20 out of 40 patients (group 1; female, 90%). In group 2, there were patients with only restless legs syndrome but with no chronic venous insufficiency (female, 80%). The mean ages of both groups were 56.4 ± 11.8 and 54.3 ± 14.7 years. Stage 1 sleep rate in group 1 was 5% ± 2.7 and in group 2 was 8% ± 3.8 (p = 0.006). Periodic limb movement index (polysomnography finding evaluating involuntary leg movements during sleep) was 11.4 ± 17.5 in group 1, and it was 29.4 ± 37.9 in group 2 (p = 0.006). CONCLUSION: We recommend that chronic venous insufficiency should be investigated in patients with primary restless legs syndrome diagnosis.

Spinal Cerebrospinal Fluid Leakage in Spontaneous Intracranial Hypotension: An Intrathecal Gadolinium Enhanced MR-Myelography Study.

OBJECTIVES: In the present study, the authors presented the intrathecal gadolinium enhanced MR-myelography findings of patients with spontaneous intracranial hypotension. MATERIALS AND METHODS: Intrathecal gadolinium enhanced MR-myelography (Gd-MR-myelography) examinations between October 2012 and September 2018 in patients having clinical and radiological findings of spontaneous intracranial hypotension were evaluated retrospectively. Sites and types of contrast leakages in 20 patients who met inclusion criteria were reviewed. All patients had undergone T1-fat suppressed sagittal images of cervical, thoracic and lumbar region after the off label intrathecal injection of 1 ml gadolinium-based contrast agent. RESULTS: Patients (18 female, 2 male) are aged between 23 and 62 years-old (mean age: 41.1). Cerebrospinal fluid (CSF) leakages were cervical in 6 patients, thoracic in 5 patients, lumbar in 5 patients. One patient had leakage in multiple levels on both cervical and thoracic region and another patient on both cervical-thoracic and lumbar regions. No patients had adverse effects related to intrathecal injection of gadolinium. CONCLUSIONS: Gd-MR-myelography is effective imaging modality to reveal spinal CSF leakages in patients with spontaneous intracranial hypotension.

Ictal kissing: Electroclinical features of an unusual ictal phenomenon.

PURPOSE: The study aimed to describe the electroclinical features of ictal kissing, an unusual behavior that may occur during focal seizures. METHOD: Twenty-five patients collected from four epilepsy centers and previously published reports were reviewed for their demographic, clinical, and electrophysiological features. RESULTS: Sixteen of 25 patients were female. The mean age was 32.9 years (9.9-51 years) and the average age at seizure onset was 14.5 years. All seizures were localized to the temporal lobe (TL) and lateralized to right side in 17 patients, left side in 2 patients, and unclear in 6 patients. A total of 55 ictal video electroencephalograms (EEGs) were analyzed. There were other symptoms such as speaking, spitting, hugging, and oral and upper-extremity automatisms along with different types of ictal kissing behavior during the seizures. The median duration of all seizures was 106.7±73.73s. Kissing occurred at a median time of 71s (1-95s) after the onset of seizure, and ictal epileptiform discharges usually involved TL during kissing episode. CONCLUSION: Ictal kissing is mainly associated with right TL and female gender, although association with left TL may also occurs, possibly related to the circuits involving temporo-insular structures.

Nonconvulsive status epilepticus cases arising in connection with cephalosporins.

Cephalosporins, particularly cefepime, exert neurotoxic side effects that can lead to status epilepticus. These neurotoxic side effects include myoclonus, dystonic movements, tremor, asterixis, seizure, status epilepticus, encephalopathy, and sometimes coma. Status epilepticus, particularly nonconvulsive status epilepticus (NCSE), is a well-known but unusual complication in patients with altered renal function who were receiving treatment with intravenous cephalosporins, especially cefepime. We reviewed the clinical and electroencephalographic (EEG) characteristics of 7 patients with renal failure who developed consciousness alterations with changes in EEG activity while being treated with cephalosporins. All patients developed renal failure: six patients had chronic renal failure, one patient had acute renal failure, and two patients were administered hemodialysis. Nonconvulsive status epilepticus was observed between 2 and 8 days (average of 5.6 days) after initiation of cephalosporins. Cephalosporins are epileptogenic drugs, especially when used in excessive doses or when renal function is impaired. Critically ill patients with chronic kidney disease are particularly susceptible to cefepime neurotoxicity. Clinical and electrophysiological results of patients guide the diagnosis of NCSE by healthcare providers.

Statistical shape analysis of temporal lobe in mesial temporal sclerosis patients.

BACKGROUND: Surgery is regarded as a common treatment option for patients with mesial temporal lobe epilepsy due to hippocampal sclerosis but sometimes deciding this diagnosis can be very difficult. We aim to investigate the shape differences in the temporal lobe of mesial temporal sclerosis epilepsy patients compared with healthy controls, investigating the side difference and, if present, assessing the clinical application of this situation. METHOD: The MRI scans of mesial TLE patients and controls were retrospectively reviewed. Temporal lobe data were collected from the two-dimensional digital images. Standard anthropometric landmarks were selected and marked on each digital image using TPSDIG 2.04 software. Eight anatomic landmarks were marked on images. A generalized Procrustes analysis was used to evaluate the shape difference. The shape deformation of the temporal lobe from control to patient was evaluated using the TPS method. RESULTS: There were statistically significant TL shape differences between groups. High level deformations for the left and right side from the control to patient group were seen in the TPS graphic. The highest deformation was determined at the inferior lateral temporal midpoint of the middle temporal gyri and superior temporal landmark points of both the right and left sides. CONCLUSION: Our study for the first time demonstrated temporal shape differences in TLE patients using a landmark-based geometrical morphometric method by taking into consideration the topographic distribution of TL.

A case of mycosis fungoides-like lesions developing after levetiracetam therapy.

Levetiracetam is a relatively new antiepileptic drug that has previously not been associated with severe dermatological side effects. We report the case of a 31-year-old male treated with levetiracetam for seizures who subsequently developed a mycosis fungoides-like drug reaction that resolved upon dosage reduction.
