[Cochlear implantation in Senegal: challenges, limits and perspectives].

A cochlear implant is an electronic prosthesis used in the rehabilitation of profound bilateral hearing loss. It directly stimulates cochlear nerve fibers by bypassing the hair cells. This high-performance technology, which appeared 60 years ago, has spread widely throughout the world and is regularly used in hearing rehabilitation.

Childhood Hearing Impairment in Senegal.

We recently showed that variants in explained Hearing Impairment (HI) in 34.1% ( = 15/44) of multiplex families in Senegal. The present study aimed to use community-based nationwide recruitment to determine the etiologies and the clinical profiles of childhood HI in Senegal.

[Craniofacial fibrous dysplasia: about six cases].

Fibrous dysplasia (FD) of bone is a benign, congenital and rare disease in which normal bone is replaced by fibrous bone tissue, resulting in bone deformities. It can affect any bone in the body, however craniofacial fibrous dysplasia is characterized by specific clinical manifestations, progression and therapeutic issues. The purpose of our study was to describe the diagnostic, therapeutic and evolutionary features of craniofacial FD.

Gingival metastasis of a breast carcinoma.

We report a case of metastasis to the gingiva of breast carcinoma. The breast tumor was treated with neoadjuvant chemotherapy followed by a radical mastectomy associated with axillary dissection. The gingival lesion occurred 7 months after surgery; the metastasis was confirmed by a biopsy.

[Iatrogenic common carotid artery injury secondary to an internal jugular venous catheterization].

Carotid injury occurring during venous jugular catheterization is a rare but potentially dramatic event. We report a case of compressive cervical hematoma associated with haemothorax occurred after common carotid artery injury during internal jugular venous catheterization. The diagnosis and management of this type of complication are discussed.
