Hospitalizations due to spontaneous intracerebral hemorrhage in the region of Nis (Serbia): 11-year time-series analysis.

Background: The study of seasonal variability of intracerebral hemorrhage (ICH) occurrence may contribute to a better understanding of the nature of this disease and open up new perspectives in its prevention. The aim of this study was to test seasonal patterns in the number of admissions of ICH patients and determine which months have maximal and minimal number of admissions.

Methods: The main data source for this study was a hospital-based registry at the Clinic of Neurology in Nis, Serbia.

[Blink and masseter inhibitory reflexes in Parkinson's disease].

Background/aim: Idiopathic Parkinson's disease (PD) is a chronic, progressive, neurodegenerative disorder with prevalence from 60 to 187 per 100 000 persons in general population. The aim of the study was to determine the abnormalities of the blink reflex (BR) and the masseter inhibitory reflex (MIR) in parkinsonian patients, as indices of the functional status of brainstem neuronal network, and abnormality level dependence on disease progression.

Methods: The investigation was conducted at the Clinic of Neurology, Clinical Center Nis, comprising a group of 60 subjects of both sexes, suffering from idiopathic Parkinson's disease in I-IV stages, according to the Hoehn and Yahr scale.

Diagnostic value of neurophysiological tests in the diagnosis of brain death--do we need changes in national guidelines?

For a final diagnosis of brain death one needs particular proof that the brain has fully stopped functioning. In this respect, diagnostic tests need to be used to confirm the clinical findings. Since in different countries there are various national guidelines for the determination of brain death, the aim of this study is to point to the diagnostic value of electroencephalography (EEG) and evoked potentials (EP) in verifying brain death.
