ABSTRACT

OBJECTIVE: To assess risk factors (RF) and severity grade of Posterior reversible encephalopathy syndrome (PRES) in children with hematological diseases. MATERIAL AND METHODS: We analyzed cases of PRES in children during chemotherapy (CT) and after allogeneic hematopoietic stem cell transplantation (allo-HSCT). We estimated the following RF: arterial hypertension, steroid therapy, CT, immunosuppressive therapy (IST), infection and renal injury. RESULTS: Thirty-five cases of PRES occurred in 32 patients (8 after allo-HSCT and 27 during CT) were included in this study. In the most of cases (94.3%), there were 2 and more RF. An increase in blood pressure level (88.6%), CT and IST (82.8%) administration, steroid therapy (71.4%) were the most significant for PRES development. Infectious process and the decline in renal function played a lesser role in this syndrome (31.4% and 14%). At the initial presentation of PRES, there were seizures (94.3%), a decrease of consciousness (28.6%), headache, vision disturbances and stomachache (20%). In the most of cases (91.4%), the 2nd and 3d grade according to the Common Terminology Criteria for Adverse Events (CTCAE 5.0) were observed. Brain magnetic resonance imaging (MRI) revealed the vasogenic edema of temporal (88.6%), occipital (74.3%), frontal (40%) lobes and the cerebellum (22.9%) more often than the cytotoxic edema (p=0.03). The cytotoxic edema was observed in the thalamus and the basal ganglia (2.9%) more often than in other parts of the brain (p<0.01). CONCLUSION: The majority of PRES cases are caused by more than two RF. Arterial hypertension does not have a leading role among its causes. There is a significant correlation between the grade of PRES according to CTCAE 5.0 score and RF number (p<0.05).

ABSTRACT

AIM: To find clinical criteria applied in the first hours of disease for the identification of severe ischemic stroke caused by an occlusion of proximal major arteries. MATERIAL AND METHODS: The authors have analyzed 133 medical histories of patients with the diagnosis of acute cerebral blood circulation disorder admitted in the first 6 h from onset. All patients underwent CT-angiography or digital subtraction angiography. Occlusion of the inner carotid artery, occlusion of M1-segment of the middle cerebral artery and occlusion of a major artery were considered as proximal occlusion of major cerebral arteries. Neurological status was assessed by the signs of proximal arterial occlusion (PAO). RESULTS AND CONCLUSION: Checking of 5 PAO symptoms allows the prediction of occlusion location in approximately 80% of cases. Presence of ≥3 out of 5 symptoms is characterized by 70% sensitivity and 90% specificity with regard to the occlusion of the inner carotid artery, M1-segment of the middle cerebral artery and/or a major artery. Predictive value of this model should be verified in a prospective study.

ABSTRACT

AIM: To assess the efficacy of postoperative cytoprotection with cerebrolysin in cardiac surgeries without using cardiopulmonary bypass and to analyze the changes in the blood circulation in the postoperative period in groups with- and without cerebrolysin preconditioning. MATERIAL AND METHODS: Thirty-eight patients, who underwent coronary and mammaro-coronary bypass grafting without using cardiopulmonary bypass, were included in the study. Fifteen patients received cerebrolysin before surgery. RESULTS AND CONCLUSION: Cerebrolysin improved cognitive test scores. Positive changes on anxiety and depression scales were observed as well. In the group of patients treated with cerebrolysin, quantitative parameters of the cerebral blood flow were in stable condition, with a slight increase on the 10th day after surgery, which may indicate increasing stress resistance of cells of the central nervous system after appropriate pharmacological protection.
