Transiently evoked otoacoustic emissions in children with otitis media with effusion.

Introduction. Otitis media with effusion is a common pediatric disease whose diagnosis is based on pneumatic otoscopy, pure-tone audiometry, and tympanometry. The aim of this study was to evaluate transiently evoked otoacoustic emissions in the diagnosis of otitis media with effusion as compared to tympanometry.

Diagnosis of Single- or Multiple-Canal Benign Paroxysmal Positional Vertigo according to the Type of Nystagmus.

Benign paroxysmal positional vertigo (BPPV) is a common peripheral vestibular disorder encountered in primary care and specialist otolaryngology and neurology clinics. It is associated with a characteristic paroxysmal positional nystagmus, which can be elicited with specific diagnostic positional maneuvers, such as the Dix-Hallpike test and the supine roll test. Current clinical research focused on diagnosing and treating various types of BPPV, according to the semicircular canal involved and according to the implicated pathogenetic mechanism.

Fibromatosis presenting as acute mastoiditis: a case report.

We describe the case of a middle-aged man who presented with manifestations of acute mastoiditis caused by fibromatosis of the mastoid region. A lesion of the right mastoid bone had eroded its wall and extended toward the middle and posterior cranial fossae. The macroscopic and microscopic appearance of an excised portion of the lesion established the diagnosis of mastoid fibromatosis.
