Introduction: The current study evaluates the effects of COVID-19 infection and the safety of vaccines in patients with epilepsy (PWEs). Method: The study was conducted with PWEs who were vaccinated against COVID-19. The sample was separated into two groups as those with drug-resistant epilepsy (DRE) and those with non-resistant epilepsy, and their seizure frequencies, seizure types, development of status epilepticus, changes in doses and/or types of drugs, electroencephalographs (EEGs) before and after COVID-19 infection, and vaccination with mRNA or inactivated vaccines were monitored and compared. Changes in seizure patterns were also inquired about following the administration of vaccines other than COVID-19. Results: Included in the study were 307 PWEs with a mean age of 42.62±14.74, among whom COVID-19 PCR positivity was detected in 97(31.6%). Those who experienced no increase in seizure frequency while infected with COVID-19 were significantly under monotherapy (p=0.031). The mean seizure frequency was 2.70±5.19 per year before vaccination, but increased to 3.20±5.82 after. A significant relationship was identified between abnormal EEG and increased seizure frequency across the entire sample and the mRNA group (p=0.011, p=0.004). The frequency of seizures increased significantly in the DRE patients after receiving the mRNA vaccine (p=0.023). Overall, increased seizure frequencies were observed in 29.9% of the sample during COVID-19 infection, with increases of 16.4% in those who received the mRNA vaccine, 8.6% after inactivated vaccines and 25% after non-COVID-19 vaccines. Conclusion: COVID-19 infection was found to be associated with a higher increased seizure frequency risk than being vaccinated, and COVID-19 vaccines do not differ from other vaccines in terms of the risk to PWEs.

Langerhans cell histiocytosis is known as a rare childhood disease. In this case, we wanted to share our patient's experience whose first symptom was an epileptic seizure, which attracted attention at an advanced age and revealed bilateral temporal lobe involvement. Our case was a 51-year-old male, who had been having seizures with focal onset, autonomic characteristics, impaired awareness, and occasionally secondary generalized seizures for 5 years, was admitted due to an increase in the frequency of seizures over the past 6 months. The patient was diagnosed with Langerhans cell histiocytosis as a result of pathological examination of the bronchoalveolar lavage. In cranial magnetic resonance imaging, bilateral temporal regions are hyperintense on T2 and Fluid Attenuated Inversion Recovery (FLAIR)-weighted images and hypointense and partially enhanced contrast on T1-weighted images. Additionally, central involvement of Langerhans cell histiocytosis was supported by hyperintensity in the optic chiasm, pituitary gland, and around the third ventricle on T2 and FLAIR-weighted images. Elect roenc ephal ograp hy showed sharp slow wave activity in the left anterior temporal region. After controlling our patient's seizures, we referred him to the oncology and hematology departments to regulate his treatment for primary disease. It should be noted that in late-onset Langerhans cell histiocytosis, epileptic seizures may occur as the first symptom rarely, due to secondary involvement of the central nervous system.

Numerous vaccination studies are conducted to protect against COVID-19 infection, and preclinical and clinical studies are still ongoing worldwide. During this extraordinary period, the necessity to perform COVID-19 vaccine studies and immunization programs together has emerged. Vaccine Adverse Effects (VAEs) need to be documented quickly. We aimed to determine the VAEs and to compare the frequency of VAEs between groups according to sociodemographic characteristics after the inactivated vaccine (CoronaVac) was administered to healthcare workers (HCWs) in Turkey. An online questionnaire was delivered to 4040 volunteer HCWs across the whole country who were vaccinated with CoronaVac. Sociodemographic characteristics, medical history, history of COVID-19 infection, and VAEs occurring after the first and second doses of the inactivated vaccine were evaluated. The most common local and systemic VAEs after first and second doses of the COVID-19 vaccine were reported as, pain at the injection site (37.9%; 37.6%), headache (21.5%; 16.8%), fatigue (18%; 15%), drowsiness (9.6%; 8.2%), back pain (8.8%; 8.2%), nausea (6.3%; 4.8%), and joint pain (4.7%; 4.7%). Individuals with a history of allergies (generalized or vaccine-related) and females had a higher rate of VAE. Participants aged 60 and over reported less frequent VAEs. It is extremely important to identify and document the VAEs occurring in the early postvaccination period in different groups of the community. These initial findings may provide reassurance to healthcare providers and vaccine recipients and promote confidence in the safety of this inactive COVID-19 vaccine, however longitudinal follow-up studies are recommended.

Introduction: To investigate the existence of peripheral and optic neuropathies in asymptomatic individuals with hepatitis C infection. Methods: Thirty consecutive patients who were followed in a hepatitis C outpatient clinic were recruited for electrophysiological evaluation together with 30 age- and gender-compatible healthy controls. All patients had a detailed neurological examination. The information regarding the disease duration and management with interferons were collected. Nerve conduction studies and visual evoked potentials (VEP) were recorded in all subjects. The results of the patient and control groups were statistically compared. Results: Of the patients with hepatitis C infection, 16 were females and 14 males. The mean age was 57.5 years, and the average disease duration was 6.43 years. The P100 latencies in the patient group were within normal limits, while the amplitudes were meaningfully small by comparison with the controls. There were some abnormalities in the nerve conduction studies of 15 patients. Sensorial neuropathy was detected in two patients, sensorimotor polyneuropathy in four, carpal tunnel syndrome in seven, and carpal tunnel syndrome and sensorimotor polyneuropathy as comorbid states in another two patients. The nerve conduction studies and VEP parameters were entirely normal in the control group. Conclusion: Hepatitis C-related neurological abnormalities may occur both in the central and peripheral nervous system. Mononeuritis multiplex, sensorial axonal neuropathy, and multiple mononeuropathies are some of the presentations of the peripheral nervous system involvement. The mode of infection is considered to be via vasculitic mechanisms. In addition, optic neuropathy is a known complication of interferon treatment. Autoantibodies, cytokines, chemokines, and cryoglobulins are accused to play roles in the pathogenesis. In this study, we investigated the involvement of the peripheral nervous system and optic nerves in a group of patients with hepatitis C. The results were in favor of peripheral nerve injury of various types and optic neuropathy of the axonal type. [ABSTRACT FROM AUTHOR]

Introduction: In this article, we report the data regarding treatment adherence of a group of patients with multiple sclerosis (MS) and relapsing--remitting or secondary progressive disease who were followed in the MS outpatient clinic of Bozyaka Education and Research Hospital, Izmir. Methods: We collected the demographic data of 219 patients with MS who were treated with immunomodulatory drugs and the documentary data on the disease characteristics from the patient' files. Each patient was provided a detailed questionnaire regarding treatment adherence in addition to the Beck depression scale (BDS) and Paced Auditory Serial Addition Test (PASAT). Nonadherence was defined as the discontinuation of the drug, i.e., more than one dose a month for intramuscular interferon, six doses a month for glatiramer acetate, and four doses a month for subcutaneous interferons. Statistical analyses were performed using Medcalc statistics package. For those parameters with an even distribution, the paired samples t-test was used to compare the results. Results: Of the 219 [183 relapsing remitting multiple sclerosis (RRMS) and 36 secondary progressive multiple sclerosis (SPMS)] patients included in the study, 143 patients were women and 76 were men. The mean age of the patients was 40.77±10.36 years. The mean expanded disability status scale (EDSS) score was 2.90±1.88, and mean annualized attack rate (ARR) was .65±.55. Of the 219 patients, 75.1% continued the immunomodulatory treatment. Thirty-three patients in the RRMS group and 23 patients in the SPMS group abandoned the immunomodulatory treatment. Treatment adherences were similar between patients with RRMS and SPMS (53%). Adherence revealed no correlation with age, ARR, PASAT score, and disease duration. However, higher EDSS and depression scores had significant positive correlation with adherence. Moreover, treatment adherence was noted to be lower in the group with higher education levels. Treatment discontinuation did not correlate with age, ARR, BDS, or PASAT scores. The disease duration and EDSS scores were found to be significantly correlated with treatment discontinuation. Conclusion: In this extensively followed up patients' group with multiple sclerosis, the ones with extended disease duration, higher disability, and more educated had higher rates of treatment discontinuation and lower levels of treatment adherence. The patient-reported outcomes and welldocumented treatment adherence data will contribute to the neurologists' understanding of the patients' inclinations regarding the injectable treatments and help in better management of the immunomodulatory treatments.
