Unraveling the Diversity of GJB2 Mutations in Nonsyndromic Hearing Loss: A Comprehensive Study in the Moroccan Population.

Introduction: Despite the high genetic heterogeneity of hearing loss, mutations in the GJB2 gene are a major cause of autosomal recessive nonsyndromic hearing loss (NSHL) worldwide. However, the mutation profile of GJB2 in NSHL is under-investigated in Morocco, especially among simplex cases. This study aimed to identify the spectrum and frequency of GJB2 mutations in the Moroccan population among simplex and multiplex families with NSHL.

Aneurysm of the internal carotid artery after minor trauma.

We report a rare case of posttraumatic aneurysm of the internal carotid artery. The aneurysm was surgically removed, followed by a simple postoperative course. Such lesions should be highly suspected in cases of penetration into the retroangulomandibular neck region.

[Cervical tuberculous lymphadenitis: the location of surgery].

Introduction: In spite of the current effectiveness of antibacillary chemotherapy in most tubercular sites, peripheral lymph node involvement continues to pose a challenge to treatment.

Patients And Methods: It is a retrospective study, from 2002 to 2005, of 326 patients treated at the otorhinolaryngology department of Hassan II University Hospital, Fez, Morocco, for cervical lymph node tuberculosis.

Results: The tuberculosis of lymph nodes accounts for more than 23% of all affections managed in our department.
