RESUMO
BACKGROUND: Intravenous immune globulin (IVIg) is frequently used in some neurological diseases and is also the first-line therapy in Guillain-Barré syndrome, chronic inflammatory demyelinating polyneuropathy, and multifocal motor neuropathy. We aimed to evaluate the frequency and characteristics of headaches, which is one of the most common side effects of IVIg treatment. METHODS: Patients who received IVIg treatment for neurological diseases were prospectively enrolled in 23 centers. Firstly, the characteristics of patients with and without IVIg-induced headaches were analyzed statistically. Then, patients with IVIg-induced headaches were classified into three subgroups determined by their history: no primary headache, tension-type headache (TTH), and migraine. RESULTS: A total of 464 patients (214 women) and 1548 IVIg infusions were enrolled between January and August 2022. The frequency of IVIg-related headaches was 27.37% (127/464). A binary logistic regression analysis performed with significant clinical features disclosed that female sex and fatigue as a side effect were statistically more common in the IVIg-induced headache group. IVIg-related headache duration was long and affected daily living activities more in patients with migraine compared to no primary headache and TTH groups (p = 0.01, respectively). CONCLUSION: Headache is more likely to occur in female patients receiving IVIg and those who develop fatigue as a side effect during the infusion. Clinicians' awareness of IVIg-related headache characteristics, especially in patients with migraine, may increase treatment compliance.

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.

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.

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.

n-Hexane gives cause to one of the most common toxic polyneuropathies seen in poorly ventilated factories. It is a sensory-motor polyneuropathy ending up with axonal degeneration. Nerve biopsy reveals paranodal axonal swelling and secondary myelin retraction in early stages. Myelin retraction imitates demyelination causing focal conduction block and failure before axonal degeneration emerges. This brings to mind the new category of nodo-paranodopathy described first for anti-ganglioside antibody-mediated neuropathies, which can be proved by electrophysiological re-evaluations. We, herein, discuss the clinical and electrophysiological follow-up of three patients with n-hexane neuropathy and remark overlaps with new concept nodo-paranodopathy.
