Background: To get more insight into the effects of the most widely used antiepileptic drugs (AEDs) on the pro oxi dant/ antioxidant balance in epi lep sy, a comparative analysis of the byproducts of oxidative damage and antioxidant de fense mechanisms was performed in patients with epilepsy treated with la mo trigine, carbamazepine and valproic acid. Methods: Byproducts of oxidative damage to proteins (reactive carbonyl derivatives, RCD and protein thiol groups, PSH), lipids (urinary isoprostanes, 8-epi-PGF2α) and DNA (urinary 8-hydroxy-2'-deoxyguanosine, 8-OHdG), as well as the activities of antioxidant enzymes superoxide dismutase (SOD) and glutathione peroxidase (GPX) were measured in 60 patients with newly diagnosed seizure (at illness onset and after 6 months of treatment with lamotrigine, carbamazepine or valproic acid) and in 20 healthy controls. Results: In patients with epilepsy, RCD, urinary 8-epi-PGF2α and 8-OHdG, together with SOD and GPX activities were significantly increased, while P-SH were only slightly decreased. After 6 months of treatment with AEDs, a decrease was observed in RCD, urinary 8-epi-PGF2α and 8-OHdG to values slightly higher or similar to the control, while P-SH remained unchanged. A decrease was also observed in SOD and GPX activities, although they remained significantly in creased compared to controls. Conclusions: The results of this study have shown that treatments with lamotrigine, carbamazepine and valproic acid affect the prooxidant/antioxidant balance in patients with epi lepsy.

Background/Aim. Stroke remains one of the leading causes of death and disability worldwide. The aim of the study was to determine the nursing care-associated predictors of in-hospital mortality in the patients with acute ischemic stroke (AIS) who were hospitalized at the Department of Emergency Neurology. Methods. Prospective cohort study included 59 consecutive patients with AIS admitted to the Department of Emergency Neurology, Neurology Clinic, Clinical Center of Serbia, Belgrade. The patients were followed until discharge or death. For exploring a relationship between the outcome of patients with AIS and different groups of factors, the univariate and multivariate Cox proportionate hazard regression models were used. Results. There were 32 male and 27 female patients with AIS. The mean age was 62.5 ± 15.2 years. The average duration of hospitalization was 11.1 ± 9.6 days (median 8 days; range 1-54 days). Almost 80% of patients (47/59; 79.7%) were admitted to the stroke unit, while 12 (20.3%) patients were admitted to the intensive care unit. In the univariate Cox regression analysis the significant variables (p < 0.05) were the Morse score (p = 0.030) and the type of admission unit (p = 0.029). The multivariate predictive model revealed that the type of admission unit (stroke unit vs conventional unit) [hazard ratio (HR) = 0.16; p = 0.032] was the independent predictor of in-hospital mortality in the patients with AIS. Conclusion. The results of this study showed an important role of nursing staff in the recovery of the AIS patients, as well as that admission to the stroke units versus the conventional units is the independent predictor of decreased in-hospital mortality. © 2019, Inst.

Thrombosis of dural sinuses and/or cerebral veins (CVT) is an uncommon form of stroke, usually affecting young individuals. It has a variable clinical presentation ranging from mild cases presenting only headaches, to severe cases featuring encephalopathy, coma or status epilepticus. A retrospective cross-sectional study of patients treated in the outpatient department and in-hospital during the period from 2014 to 2020 at the Neurology Clinic—University Clinical Centre of Serbia was conducted. Forty-nine patients (24 men; 25 women) were included in the study. Twenty-three patients (46.9%) suffered a subacute form of CVT (48 h—4 weeks), 19 (38.8%) presented with an acute form (< 48 h) and 7 (14.3%) with a chronic form (> 4 weeks). Around 75% of patients reported headaches during disease course. Focal neurological deficit (FND) was observed in 27 (55.1%) patients. Patients who did not report headaches (22.4%) presented with more severe symptoms (seizures and coma). More than 70% of patients had no radiologically evident brain parenchymal lesion. The most frequent locations of CVT were transverse sinus (79.6%), sigmoid sinus (44.9%) and superior sagittal sinus (36.7%). Thrombosis of more than one sinus/vein occurred in 33 (67.3%) patients. Hereditary thrombophilia was observed in 9 (18.4%) patients, 11 (22.4%) patients had some type of infection and 20% of women reported OCT usage. As much as 25% of cases remained without evident risk factors. The most common symptom in our cohort was acute unilateral throbbing headache of high intensity, while patients without headaches had more severe symptoms. © 2021, Fondazione Società Italiana di Neurologia.

Guillain–Barré syndrome (GBS) in pregnancy may be a serious disease associated with high maternal and perinatal morbidity and mortality. Herein, we present the long-term maternal and fetal outcomes of five pregnant GBS patients from our center. The mean age of pregnant GBS patients was 29.8 ± 3.1. Two patients had a severe disability at admission. Three patients were treated with intravenous immunoglobulins, while the remaining two were treated with symptomatic therapy. One year after disease onset, one patient had a mild disability, while the remaining four had normal neurological findings. All babies born were healthy and developed normally. GBS in pregnancy may affect both maternal and neonatal outcomes. Early diagnosis and treatment are essential for the outcome. Most patients and their babies have a favorable long-term outcome. © 2021 Japan Society of Obstetrics and Gynecology.

Herpes simplex encephalitis (HSVE), manifesting with non-convulsive status epilepticus (NCSE), normocellular CSF findings and CT features of acute ischemic stroke, is a rare finding that can be hard to diagnose accurately. We present a case of HSVE and compare our results to those of previously published cases with the same pathology, in order to provide information to support more rapid and effective diagnosis and treatment. A Pubmed search of reported cases was conducted and five cases of HSVE manifesting with NCSE were found. Each of the cases, including ours, was compared in terms of clinical manifestations and CSF, CT and EEG findings. The clinical manifestations in our patient correlated with those of the other cases. EEG showing sharp fronto-temporo-centro-parietal waves was only observed in our patient. Similar CT manifestations were found in one other patient, normocellular CSF was registered in three other cases and positive PCR for HSV in four patients. Information about the possible clinical manifestations and CT, EEG and CSF findings in patients with HSVE manifesting with NCSE is crucial for a fast diagnosis and successful treatment, leading to higher survival rates and fewer complications and neurological deficits. © 2021 Epileptic Disorders

Background: Central nervous system involvement is rarely described in eosinophilic granulomatosis with polyangiitis (EGPA) and occurs in 5–9% of patients. Among central nervous system manifestations, cerebral infarctions are the most common. To the best of our knowledge, a recurrent stroke in patients with EGPA without cardiac risk factors during maintenance therapy so far has not been described. Case presentation: A previously healthy 57-year-old female during the course of 1 year developed asthma, sinusitis, polyneuropathy, muscle weakness, and rash followed by fatigue, myalgia, arthralgia, and fever. After an initial diagnostic evaluation, elevated values of eosinophils, liver enzymes, creatine kinase, lactate dehydrogenase, and inflammatory markers (sedimentation rate and C-reactive protein) were found, and renal impairment was detected. On the third day of hospitalization, she developed left-sided hemiparesis due to an ischemic stroke in the right basal ganglia. She has been diagnosed with EGPA, and oral corticosteroid, immunosuppressive, and antiplatelet therapy were applied. Despite potent treatment and initial recovery, a few weeks later, she developed recurrent ischemic stroke in the left hemisphere and pulmonary embolism as rare and potentially severe complications of EGPA. Assuming that complete disease remission had not been established previously, oral prednisone was initially substituted with intravenous methylprednisolone pulses. During follow-up, immunosuppressive therapy was slowly discontinued, oral corticosteroid therapy was reduced to a maintenance dose, and thromboembolic events were well controlled by oral anticoagulant therapy. Conclusion: Anticoagulant therapy, in addition to immunosuppressive maintenance therapy, should be considered in any EGPA patient who has had an ischemic stroke even without cardiac risk factors. © 2021, The Author(s).

Introduction: There are no many data on association between progression rate of Guillain-Barré syndrome (GBS) and disease outcome. Aim: The aim of our study was to analyze short-term outcome of GBS in relation to the rate of disease progression. Methods: Our retrospective study included patients diagnosed with GBS in seven tertiary healthcare centers from 2009 to 2014. According to the rate of disease progression from onset of symptoms to the nadir, patients were divided in three groups: rapid-onset GBS (nadir reached in maximum 48 h), gradual-onset (nadir reached in three to 14 days), and slow-onset (nadir in 15 to 28 days). GBS disability scale (GDS) was used to assess functional disability at nadir and on discharge. Results: Among 380 patients included in the study, 24 (6.3%) patients had rapid-onset, 274 (72.1%) gradual-onset, and 82 (21.6%) slow-onset GBS. Time from the onset of the disease to the hospital admission was much shorter in faster-onset forms (3.0 ± 4.1 days in rapid-onset vs. 6.8 ± 9.5 days in gradual-onset and 21.0 ± 9.6 days in slow-onset GBS, p < 0.01). Preceding events were less commonly identified in slow-onset forms. Patients with rapid-onset GBS were more likely to have axonal variants (p < 0.05). All three groups of patients were treated in a similar way, and there were no differences in GDS score at nadir (p > 0.05) and on discharge (p > 0.05) and no differences in the duration of hospital stay. Conclusion: Faster progression of GBS does not imply a poorer short-term functional outcome of the disease. © 2020, Royal Academy of Medicine in Ireland.

Introduction: Poststroke infections are the most common medical complications of stroke and can occur in up to 65% of patients. The aim of this study was to assess the rate of infectious complications during hospitalization of stroke patients and to evaluate the impact of infection in general, including each of the urinary tract infection (UTI), pneumonia, and sepsis, on fatal and poor functional outcome at discharge. Methods: This retrospective study enrolled patients who have been diagnosed with acute ischemic stroke treated in a 1-year period. Poor functional outcome at discharge was defined as severe invalidity and included patients with modified Rankin Scale score of 3-5. Univariate and multivariate analyses were performed. Results: We analyzed 133 patients with acute ischemic stroke. Poststroke infection occurred in 63 (47.4%) patients. The most common infection was UTI that was present in 27 (20.3%) patients. Multivariate logistic regression analysis after adjustment for confounders demonstrated that poststroke infection was an independent predictor of poor functional outcome (odds ratio [OR] 12.82, 95% confidence interval [CI] 4.09-40.0, P <.001) and death at discharge (OR 14.92, 95% CI 2.97-76.92, P = .001). When analyzing the impact of each infectious complication, multivariate logistic regression showed that UTIs were an independent predictor of poor functional outcome (OR 14.08, 95% CI 3.06-64.84, P = .001) and death (OR 9.81, 95% CI 1.46-65.68, P = .019) at discharge. Conclusion: Infection is a frequent poststroke complication and represents an independent predictor of poor functional and fatal early stroke outcome. © 2013 by National Stroke Association.
