Review
[Causes, diagnosis and treatment of neurogenic dysphagia as an interdisciplinary clinical problem].
The intricate mechanism of swallowing can be divided into three phases: oral, pharyngeal, and esophageal. Dysphagia is a disruption in the swallowing process, which include difficulty in transporting (or a lack of transporting) a food or liquid bolus from the mouth through the pharynx and esophagus into the stomach. Causes of disruptions in the swallowing process can be divided into superior (oropharyngeal) and inferior (esophageal) according to Paradowski et al. ⋯ The basic principle of dysphagia rehabilitation is that the most effective way to regain efficiency is the regeneration on remains of lost function. Carrying out imperfect swallowing acts is probably the best way of increasing effectiveness and efficiency of swallowing. On the other hand imperfect swallowing acts may be hazardous because of the danger of aspiration and inhalation pneumonia.

Comparative Study
[Otoacoustic emissions measurements in children during the chemotherapy because of the acute lymphoblastic leukemia].
Chemotherapy is associated with an increased risk of ototoxic changes. The predictive value of conventional pure-tone audiometry on early detection of ototoxicity has been questioned. Otoacoustic emissions (OAEs) appear to be more sensitive to cochlear insult than the conventional pure-audiometry. The purpose of our study was (a) investigation the clinical usefulness of Distortion Product Otoacoustic Emissions (DPOAEs) as early indicator of chemotherapy-induced ototoxicity, (b) determination which of the protocols of chemotherapy is most ototoxic as measured by DPOAEs, (c) comparison of the short-term and long-term effects of chemotherapy on DPOAEs. ⋯ Distortion product otoacoustic emissions measurements are very sensitive on early detection of the changes in cochlear function and are recommended for monitor hearing in patients during chemotherapy.

The aim of the study was to assess the influence of hyperbaric oxygen on regeneration processes which take place in the inner ear (basilar papilla - BP) of chicken after exposure to wide-band noise at the level 120 dB for 48 hours. We found, that hyperbaric oxygen applied once a day after exposure to the noise restricted he extensiveness and decreased the dynamics of hair cells injury. Quantative and qualitive differences in histological changes which take place in chick basilar papilla after exposure to hyperbaric oxygen and glucocorticoids may prove the presence of different their effectory points of acting.
