[Contemporary view on mild brain injuries in adult population]. / Nácrt súcasného pohl'adu na problematiku l'ahkých poranení mozgu so zameraním na dospelú populáciu.

Mild brain injury is one of the most common neurological a neurotraumatological diagnoses. The pathophysiological basis of mild brain injury is frequently a diffuse axonal damage of variable degree. In the acute phase of mild brain injury we have to identify 1% of patients who will undergo neurosurgery because of vital need. The analysis of patient's personal history, screening of risk factors, neuropsychological testing and imaging methods (CT, MRI) are irreplaceable in the diagnostic process of mild brain injury. Though the mild brain injury is currently considered as an irrelevant traumatic event, approximately 10% of patients develop the so-called post-concussion syndrome.

[Classification of anterior instability of the shoulder by arthroscopy - the authors clinical material.]. / Klasifikácia prednej instability ramena v artroskopickom obraze v nasom klinickom materiáli.

The authors review briefly the evaluation of anterior instability of the shoulder joint from different aspects. The objective of their work was to present different types of morphological changes, as suggested by Resch (6). During the two-year period since June 1995 so far a total of 96 patients with the clinical picture of anterior instability of the humeroscapular joint were examined arthroscopically. The group comprised 69 men and 27 women, all in productive age. Type 1 lesions according to Resch were found in 52 %, type 2 in 21 %, type 3 in 6 %, type 4 in 13 %, type 5 in 1 % and type 6 in 7 % of the patients, which is consistent with data reported in the literature. In their opinion type 5 lesions are most difficult to diagnose. A certain amount of routine is needed also to differentiate type 1 and 4 and type 2 and 6 according to Resch's classification. Conversely, they consider type 3 findings standard and unequivocal. Key words: humeroscapular joint, anterior instability, arthroscopic diagnosis, type of lesions.

[Impingement syndrome - diagnosis and treatment.]. / Impingement syndróm - diagnostika a liecba.

In the introduction the authors describe the anatomical features of the subacromial space from which the concept of impingement syndrome is derived. In a review of the literature they describe the development of views on the pathology of the subacromial space. According to Neer (11) impingement syndrome develops i three stages. In the subsequent part of the paper the authors describe structural and functional changes which have an impact on the course of the impingement syndrome. They emphasize detailed assessment of the patient's subjective complaints and describe the comprehensive clinical examination as well as X-ray imaging methods. The subsequent part is devoted to conservative and surgical treatment with special attention to arthroscopic and open subacromial decompression. The final part of the paper deals with the problem of after-treatment. Key words: impingement syndrome, anatomical definition, diagnosis and treatment of subacromial decompression after-treatment.
