Prolonged diplopia following sinus vein thrombosis mimicking Gradenigo's syndrome.

We report about a boy with the symptoms of Gradenigo's syndrome (abducens nerve palsy, acute otitis media, unilateral headache). The MR imaging showed a sinus vein thrombosis instead of the expected petroapicitis. After 2 weeks of conservative therapy with antibiotics and anticoagulation, without any clinical effort the boy underwent a mastoidectomy.

Measurement of tracheal humidity and temperature.

Background: After tracheostomy, patients often present with chest complaints. Measurement of objective parameters of the tracheal climate is important to evaluate 'artificial noses' or humidifying devices.

Objectives: The purpose of this study was to present an experimental setup for measurement of tracheal temperature and humidity for possible use in clinical studies in tracheotomized patients.

Nasal mucosal temperature after exposure to cold, dry air and hot, humid air.

Objective: To determine the influence of variations in the temperature and humidity of inhaled air on the nasal mucosal temperature at various sites in the nasal airways.

Material And Methods: Fifteen volunteers were enrolled in the study. The temperature was measured on the mucosal surface of the nasal septum at the level of the nasal vestibule, in the nasal valve area, anterior turbinate area and choanae.
