[Experimental studies of mechanism and efficiency of sclerosing agents: varicocid and paraffin].

Based on the analyse of publications the authors treated of history and contemporary applications of sclerotherapy. The role, methodics and results of sclerosing therapy among patients with oesophageal varices were also presented. The aim of the study was to examine the mechanism and efficiency of two sclerosing agents which are frequently used in Poland.

[Investigations of the ototoxicity of dicortinef (ear drops)].

The authors investigated the ototoxic influence of Dicortinef in laboratory animals. Their examinations were performed on 15 guinea pigs (weighing 210-380 g.) after application of this medicine to the fenestra rotunda.

[Tracheo-arterial fistula as a complication of tracheotomy].

The authors presented 2 cases of massive bleeding from brachiocephalic artery as a late complication after tracheotomy.

[Histological and electron microscopic examinations of laryngeal papilloma in children and adults].
