Objective: To investigate the relation of surgical treatment with patient’s 180-day outcome. Subject and method: Thirty-six patients who suffered a first spontaneous cerebellar hemorrhage (SCH) were treated with operation from January 2017 to March 2022. This study aimed to identify potential clinical and computed tomography (CT) features influencing outcomes after 6 months from ictus, and the association of surgical treatment with SCH patients. Result: The mean age was 62.9 years (IQR 43–83 years). Hypertension was the most common underlying disease (31 patients, 86.1%), followed by smoking (15 patients, 41.7%). 63.9% (23/36) of patients showed loss of consciousness at the initial presentation. Among 36 patients, 25 patients (70%) underwent surgical hemorrhage evacuation with placement of an external ventricle drainage (EVD), 4 patients (10.4%) received an EVD only. The six-moth mortality rate was 33.33%, 12 patients (33.34%) had good outcome (modified Rankin Scale – mRS < 3). In multivariate analysis only the Glasgow coma scale (GCS) score and intracerebral hemorrhage (ICH) score on admission was significant predictor of six-month outcome ([odds ratio (OR) = 1.50, 95% confidence interval (CI): 1.08-2.08, p=0.01; OR = 0.32, CI: 0.10–1.05, p=0.03), respectively. Conclusion: Surgical treatment can be effective for selected patients without lower GSC scores on admission. However, a higher ICH score on admission was associated with a 180-day outcome in patients with SCH.

Objective: To determine clinical characteristics, computer tomography brain imaging, and surgical outcome for elderly patients with chronic subdural hematoma (CSDH). Subject and method: A cross-sectional, descriptive, and retrospective study was conducted on 74 elderly patients diagnosed with CSDH and operated at 108 Military Central Hospital from June 2020 to June 2021. Result: Mean age was 75.2 years; male/female ratio was 3.93/1, the most common cause was traumatic brain injury (49%). The common presenting symptoms of CSDH were altered mental state (70.9%) and headache (68.9%), followed by cognitive impairment (54.1%), hemiparesis (21.6%), hematoma maximal thickness and midline shift were associated with a higher rate of hemiparesis in CSDH patients (p<0.05); The percentage of patients with GCS score ≥ 13 was 90.5%. The portion of unilateral on the brain CT was 78.4%. The most common densities of CSDH obtained from CT imaging was isodense (accounting for 54.0%); followed by hypodense (20.3%), high-density (17.6%), and mixed-density (8.1%); The most common complication of burr hole technique was pneumocephalus (accounting for 8.1%); recurrence of CSDH (5.4%). The Glasgow outcome scale (GOS) 4-5 was 89.7% within 3 months. Conclusion: Chronic subdural hematoma was one of the most common diseases in neurosurgery. The burr hole drainage technique was safe and effective.

Methods and means of monitoring the state of the rail track by a number of key geometric parameters are analyzed. The concept of joint use of inertial and optical technologies as an accurate and cost-effective solution in this area is proposed. An assessment of the influence of errors of individual measuring modules of an optical-inertial diagnostic system on the accuracy of determining the geometric parameters of a rail track has been carried out. Questions related to the recognition of the rail image in the readings of optical sensors against the background of stray lighting and sun glares are touched upon. Attention is paid to the methods of obtaining a priori data on the position of the rail head profile on the matrix of the scanner camera. The results of experimental testing of the proposed solutions are presented. The current approach to the indirect assessment of the dynamical behavior of a railway mobile unit’s bogie in a track is analyzed. An approach is proposed for direct control of this dynamics without introducing an intermediate parameter of equivalent conicity.
