[The results of sudden deafness treatment]. / Wyniki leczenia osób, u których wystapila nagla gluchota.

In years 1980-1994, 180 sudden hearing loss cases were diagnosed and treated. Sudden deafness is a symptom of a variety of diseases. Time is often the most important factor in the overall recovery. However the etiology was difficult to identify, precise examinations permitted to determine the probable diagnosis and to apply appropriate treatment. In cases with expected vascular etiology Nimodypine was additionally employed with good results. The most frequent reason for sudden hearing loss was vascular factors (50%), next viral infections (25%), acoustic trauma (10%), allergy (5%), and unknown causes (10%). The best results were obtained in the patients under treatment between 1 and 7 days of sudden deafness persistence. Remarkably better results were received in cases of sudden deafness concerning wide frequency band than in those within high tones only.

[Reactivity of the bronchi as a function of their initial state in children with asthma]. / Reaktywnosc oskrzeli jako funkcja ich stanu wyjsciowego u dzieci chorych na astme.

The aim of the study was to assess the effect of peripheral bronchial base-line status on the result of the bronchial provocation test. The study was carried out on a group of 65 children with bronchial asthma. Bronchial reactivity was assessed utilizing the carbachol provocation test. Higher reactivity was seen in children with initially lower indices of peripheral bronchial flow (MEF50, MEF25) (PC20 = 3,789 +/- 0.014 mg/ml) in comparison with children with normal indices (PC20 = 74,608 +/- 0,038 mg/ml) (p < 0.001). A linear correlation was found between the results of bronchial provocation (PC) and initial standardized small airway flow values (MEF50 - r = 0.56, p < 0.001; MEF25 - r = 0.49, p < 0.001). The correlation between bronchial provocation and initial FEV1/VC was weaker (r = 0.39 p < 0.01). The authors conclude that demonstration of decreased flow in peripheral, small airways utilizing MEF values enable to predict a positive result of bronchial provocation tests.
