Bone mineral density measurements in otosclerosis using dual-energy X-ray absorptiometry.

OBJECTIVES: This study aims to evaluate patients with otosclerosis with respect to bone mineral density (BMD) at different regions of interest (ROI), using dual-energy X-ray absorptiometry (DXA). DESIGN: Cross-sectional controlled study. SETTING: Tertiary referral hospital. PARTICIPANTS: The patients with a definite diagnosis of otosclerosis confirmed intra-operatively were defined as the study group (n = 30). The control group consisted of volunteer, healthy subjects with normal hearing (n = 43). MAIN OUTCOME MEASURES: Following an audiometric evaluation, a venous blood sample was obtained and a single BMD measurement using DXA was applied to each participant. RESULTS: The mean BMD, T and Z scores were higher in the otosclerosis group than in the control group in all the regions considered, but not significantly; only the L2-L3 lateral BMD and its T and Z scores were significant (P = 0.036, P = 0.029 and P = 0.036, respectively). CONCLUSION: This study shows that the BMD does not decrease in the presence of otosclerosis despite its genetic and metabolic relevance with osteoporosis. Concerning the L2-L3 lateral BMD measurements, the BMD increased in otosclerosis.

Prevalence of oral lesions in 13- to 16-year-old students in Duzce, Turkey.

OBJECTIVE: The aim of this study was to determine the prevalence of oral lesions in 13- to 16-year-old students. METHODS: A cross-sectional survey was carried out on students in Duzce, a province in the western Black Sea region of Turkey. A total of 993 children aged between 13 and 16 from eight secondary schools were examined. Oral lesions with recurrent behavior, if observed, were recorded at the time of examination. Venous blood samples were obtained for detecting hemoglobin levels. RESULTS: Two hundred sixty adolescents (26.2%) were diagnosed with at least one oral mucosal lesion at the time of the examination. Thirteen different mucosal alterations were diagnosed, and the most common lesions were angular cheilitis (9%), linea alba (5.3%), and aphthous ulceration (3.6%). The correlation between occurrence of mucosal lesions and sex was not statistically significant (P > 0.05). Statistical evaluation of the data revealed a significant relationship only between the presence of angular cheilitis and anemia (P < 0.05). CONCLUSION: This study is the first epidemiologic study of oral mucosal lesions in adolescents in Turkey. Angular cheilitis was the only oral mucosal lesion that had a significant correlation with anemia.

Transmaxillary excision of a rare cavernous hemangioma of the infratemporal fossa.

Cavernous hemangiomas that manifest as a primary tumor of the infratemporal fossa are exceedingly rare. We report such a case in a 40-year-old woman. Her lesion was excised via a transantral anterior approach. Although this approach is usually recommended only for biopsy, in selected cases it can be used to excise a lesion without causing any significant complications. We recommend the transantral anterior approach for relatively small, benign lesions that show no evidence of invasion into surrounding tissues because it does not expose the patient to surgical complications such as transient or permanent facial nerve injury or cosmetic deformity.

Sinus histiocytosis with massive lymphadenopathy (Rosai-Dorfman disease).

Sinus histiocytosis with massive lymphadenopathy (SHML) is a distinct clinicopathological entity described by Rosai and Dorfman and differentiated by other childhood histiocytoses by its distinct characteristics. This is a rare pathology and should be kept in mind for differential diagnosis of neck masses, especially in childhood. In this article a case with SHML is presented and clinical features of the disease given.
