The aim of the study was to assess the influence of glucocorticoids on the view of hair cell regeneration process being in the chicken's inner ear (basilar papilla - BP) after exposure to wide-band noise at the level 120 dB (A) for 48 hours. We found that glucocorticoids given during and/or after exposure to the noise have a cytoprotective activity to the hair cells, they limitate the extensiveness and decrease the dynamics of hair cells injury. We observed that new "young" hair cells reappeared at the sensory epithelium on the 7th day after the end of exposure. Regenerated hair cells have immature, short and thick cilia and small apical surface area.

A foreign body in the parotid gland is extremely uncommon. It can penetrate to the parotid gland through the skin or from the oral cavity via the Stenonís duct. A case of 23-years-old man with the several pieces of glass within the superficial lobe of the right parotid gland was described. The surgical removal was performed and the diagnosis of the foreign body was quite easy.

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.

Biography Historical Article
[Tadeusz Antowski Ph.D. (1919-1966), from ENT Unit in Dachau to the lectureship in Otolaryngological Clinic of Poznań University].
The authors present the biography of the laryngologist Tadeusz Antowski Ph. D. (1919-1966). The medical studies at the University of Poznań, which he started with his brother Marian (1915-1943), were interrupted by World War II. ⋯ Soon he was called up to the military service and in 1951 became the chief of Otolaryngological Department in the 8-th Army Hospital in Toruń. He was an active member of Polish Medical Association and the president of the Toruń branch. Tadeusz Antowski died on 02.11.1966 in Gdańsk.
