Objective: Intoxication may mimic brain death and cause brain death. In the literature, brain death due to methanol intoxication is limited to case reports. In this report, patients with methanol intoxication who had findings of imminent brain death were evaluated. Materials and Methods: The study population consisted of patients with methanol intoxication treated in the adult intensive care unit (ICU) between October 2014 and October 2020. The records in the hospital automation system of patients with methanol intoxication were evaluated retrospectively. According to the outcomes, the patients were divided into two groups: survivors and patients who had imminent brain death. Results: Eighteen patients with methanol intoxication were investigated. The brainstem reflexes disappeared in seven patients who were in a coma. The imminent brain death rate of patients with methanol intoxication was 39%. Patients who had imminent brain death had lower Glasgow Coma Scale scores during ICU admission and a higher ratio of pathologic neuroimaging findings due to methanol intoxication (P < 0.05). According to the clinical criteria and ancillary tests, four patients were declared brain dead. The brain death rate of patients with methanol intoxication was 22%. One of four patients with brain death was an organ donor. The liver was transplanted from our donor. Conclusion: Treatment should be initiated immediately in cases of methanol intoxication. Patients who do not respond well to treatment should be followed closely in terms of brain death. Based on published data and our personal experience, organ donations can be performed after appropriate investigations in brain death cases due to methanol intoxication.

Objective: Our goal was to identify the frequency and types of involuntary movements in immune mediated and hereditary polyneuropathies. Methods: In this prospective study, we included all consecutive patients with immune mediated or hereditary polyneuropathy between January 2017 and November 2019. The presence and type of the involuntary movements were determined by the clinical examination and multichannel surface electromyography. Results: We identified 23 (48.9%) patients with involuntary movements among 47 patients with immune mediated or hereditary polyneuropathy in the study period. All patients with an involuntary movement had postural tremor with accompanying action and/or rest tremor. Short duration and high-amplitude myoclonus was accompanying in 18 (38.3%) patients. The demographic and clinical characteristics and features of nerve conduction studies were similar between patients with and without involuntary movements. Discussion: Tremor and myoclonus were frequent in our cohort. Postural tremor was the most frequent subtype. There was no significant relationship between myoclonus or tremor and clinical/electrophysiological features. Conclusion: For assessing movement disorders in polyneuropathies not only clinical examination, but also electrophysiological studies such as multichannel surface electromyography should be used.

Introduction: Coronavirus disease 2019 (COVID-19) is known to have higher morbidity and mortality rates, parallel to the increased risk factors in the elderly. We aimed to define the risk factors related to mortality and morbidity in older patients hospitalized with COVID-19 disease in this study. Materials and Methods: This retrospective cross-sectional study included patients aged ≥65 years who were hospitalized with a confirmed diagnosis of COVID-19. We analyzed their demographic data, clinical findings, comorbidities, laboratory and radiologic findings, treatment protocols, and outcomes. Results: A total of 58 patients were included in the study. A total of eight (13.8%) patients died during the clinical follow-up and treatment, and 50 (86.2%) patients were discharged. The most common comorbidities among all patients were hypertension (HT) (69%) and diabetes mellitus (39.7%). The most common symptoms include fever (51.7%), cough (44.8%), and dyspnea (43.1%), and the most common neurologic findings were headache (27.6%) and impaired consciousness (27.6%). Intensive care unit admission was significantly higher among patients with comorbidities of HT, cerebrovascular disease, atrial fibrillation (AF), and chronic obstructive pulmonary disease. The rate of death was significantly higher in patients with a history of smoking, cerebrovascular disease, AF, and HT. Although there was a statistically significant positive correlation between the death rate and leukocyte, neutrophil, C-reactive protein, lactate dehydrogenase, D-dimer, interleukin-6, and procalcitonin levels, a negative correlation was observed in lymphocyte levels. Conclusion: Age-related comorbid conditions, especially HT, cerebrovascular disease, and AF, caused increased morbidity and mortality rates in older patients with COVID-19.

Introduction: Respiratory complications are important in the prognosis of amyotrophic lateral sclerosis (ALS). The aim of this study was to determine the electrophysiological findings that may predict respiratory failure. Methods: According to the Awaji electrodiagnostic criteria, 30 patients with ALS who were diagnosed with definite or probable ALS without respiratory failure were included in the study. Nerve conduction studies, needle electromyography (EMG), and single-breath count tests were performed in all patients. In addition, the pulmonary function tests, swallowing EMG, and arterial blood gas analysis of the patients were recorded and evaluated. The patients were followed until respiratory failure developed. Results: As a result of 18 months of follow-up, 26 of 30 patients developed respiratory failure. When the contribution of the accessory respiratory muscles to the respiratory effort before the development of respiratory failure was evaluated clinically and electrophysiologically, it was observed that the most common muscles involved in the respiratory effort were sternocleidomastoid (SCM), trapezius, and rectus abdominis. Before the development of respiratory failure, the latest neurogenic EMG findings were seen in the SCM (50% cases), trapezius (20% cases), and thoracic paraspinal muscles (17% of cases), respectively. It was thought that this finding could be an important early electrophysiologic marker in predicting the development of respiratory failure in ALS cases. Conclusions: To sum up, the presence of neurogenic changes in certain muscles in needle EMG and demonstration of the contribution of certain accessory respiratory muscles in respiration can be used as an electrophysiological marker to predict the development of respiratory failure.
