Case Report of Atlantoaxial Rotatory Fixation after Cochlear Implantation.

Atlantoaxial rotatory fixation (AARF) is a relatively rare condition and is mainly seen in children. We report of a 7-year-old girl suffering from AARF after cochlear implantation (CI). Fortunately, early diagnosis based on three-dimensional computed tomography (3DCT) was made, and the patient was cured with conservative therapy.

Late pneumolabyrinth may be induced by old penetrating injury: possibility of undiagnosed posttraumatic perilymphatic fistula.

Traumatic pneumolabyrinth is a relatively rare entity. We report the case of a unilaterally deaf woman with pneumolabyrinth who had suffered penetrating injury 15 years ago. This past history indicated that the case was late pneumolabyrinth occurring from undiagnosed old posttraumatic perilymphatic fistula.

Extravascular papillary endothelial hyperplasia arising from parapharyngeal space.

A 66-year-old man visited our clinic suffering from swelling of right pharyngeal space. He was not aware of other symptoms. The contrast CT showed patchy enhancement with calcification.

The role of nuclear factor-kappa B in interleukin-8 expression by human adenoidal fibroblasts.

Objectives/hypothesis: The production of cytokines by adenoids is known to be associated with inflammation of nasopharynx and the pathogenesis of otitis media with effusion. However, the role of adenoids in producing inflammatory cytokines such as interleukin-8 (IL-8) is not yet clear. In the present study, expression of IL-8 in adenoidal fibroblasts was investigated at the level of transcription factors.
