[Results of a functional magnetic resonance study of the primary auditory cortex (I): general characteristics and individual outcomes].

Objective: To demonstrate and investigate the activation patterns of the primary auditory cortex (Heschl's gyrus) using functional magnetic resonance imaging (fMRI).

Material And Methods: Pure tone stimuli at 750 Hz and 2000 Hz were delivered to the right and left ear of 32 normal-hearing volunteers (18-49 years old) in 20-second on-off cycles. The fMRI data were obtained using a 1.

Activation patterns of the primary auditory cortex in normal-hearing subjects: a functional magnetic resonance imaging study.

Conclusions: These results demonstrate that functional magnetic resonance imaging (fMRI) is an optimal tool to investigate the auditory cortex. The study suggests that there is a medio-lateral gradient of responsiveness to high frequencies medially and low frequencies laterally. The contralateral auditory cortex is more responsive than the ipsilateral cortex to tones presented monaurally.

Epiglottitis and necrotizing fasciitis: a life-threatening complication of infectious mononucleosis.

Life-threatening cervical complications associated with infectious mononucleosis are rare. The combination of acute epiglottitis and subsequent necrotizing fasciitis of the head and neck in a patient with infectious mononucleosis has not been reported to date.A 47-year-old female with infectious mononucleosis and epiglottitis was admitted to hospital for i.

Peripheral primitive neuroectodermal tumour of the left maxillary sinus.

Peripheral primitive neuroectodermal tumours (pPNETs) are highly malignant, small-cell neoplasms found mainly in children and young adults. Recent advances in immunohistochemistry and genetic typing have led to reports of a close relationship between pPNET and the previously difficult-to-classify Ewing's sarcoma. We report a case of pPNET involving the left maxillary sinus in a 23-year-old female who presented with a 2-month history of unilateral left-sided nasal obstruction, rhinorrhoea and recurrent bloody nasal discharge.

[Laryngeal rhabdomyoma: unusual case of dysphonia. Review of the literature].

Rhabdomyomas of the larynx are extremely rare benign tumors. Only 25 have been well documented until now. These tumors display a low growing pattern.
