[The odontogenic maxillary sinusitis: 31 cases].

Background: The odontogenic maxillary sinusitis is the consequence of the distribution of an inflammatory or infectious process of a tooth in sinuses mucous membranes.

Aim: The purpose of our work is to study epidemiological profile, clinical and radiological characteristics allowing the diagnosis of this pathology as well as the various therapeutic strategies adopted.

Methods: We report a retrospective study of 31 observations of odontogenic maxillary sinusitis brought together in the service of ORL and of CMF of Rabta hospital over a period of 12 years.

A new locus for otosclerosis, OTSC8, maps to the pericentromeric region of chromosome 9.

Otosclerosis is a common disorder of the otic capsule resulting in hearing impairment in 0.3-0.4% of the Caucasian population.

Clinical and genetic analysis of two Tunisian otosclerosis families.

Otosclerosis is caused by an abnormal bone homeostasis of the otic capsule resulting in a conductive hearing loss when the free motion of the stapes is compromised. An additional sensorineural hearing loss arises in some patients, most likely due to otosclerotic foci that invade the cochlear endosteum. Otosclerosis is a very common hearing impairment among Caucasians with a prevalence of about 0.

[Acute otomastoidïtis in children, about 44 cases].

Background: Acute mastoiditis with ostertis is secondary to bacteria involving mastoid cavities

Aim: Describe the epidemiologic aspects

Material And Methods: Between 1990 and 2003, we listed 44 files of children hospitalized for acute mastoiditis. The treatment was in any case medical associated to a surgical treatment in 30 cases.

Results: The age of our patients was consisted between 2 months and 14 years with an average is 2 years.

[Rhinoscleroma: a report of 2 cases].

Rhinoscleroma is a rare chronic granulomatous infection caused by Klebsiella rhinoscleromatis. Because of its mundane clinical presentation as chronic rhinits, it is frequently unrecognized. The authors report the cases of two female patients with pseudotumoral rhiniscleromas located in the septum and in the rhinopharynx respectively CT scan permitted a precise evaluation of the extent of the lesion.

Mutation analysis of TBX22 reveals new mutation in Tunisian CPX family.

Cleft palate with ankyloglossia (CPX; OMIM 303400) is inherited as a Mendelian semidominant X-Linked disorder. Linkage studies resulted in mapping CPX to Xq13-q 21-31 region. TBX22 was identified as causing CPX.

Consanguinity and endogamy in Northern Tunisia and its impact on non-syndromic deafness.

Deafness is an important health problem in the Tunisian population, especially in isolates where the prevalence ranges from 2 to 8%. To evaluate the effect of inbred unions on deafness, a study was conducted on 5,020 individuals (160 are deaf) between 2000 and 2002 in the North of Tunisia. The coefficient of inbreeding for all individuals and the levels of inbreeding in ten districts were computed.
