Enlarged vestibular aqueduct(EVA), the most frequent identifiable cause of congenital hearing loss, is evaluated with high-definition multidetector CT in the axial plane. Our purpose was to determine which reformatted CT measurements are most reproducible. Seven multiplanar reformatted images were created for each of the 64 temporal bones in patients with EVA. Intraclass correlation coefficients(ICC) were used to assess inter-observer variability, and both linear regression and ROC analyses were used to compare the measurements with severity of hearing loss, as assessed by pure tone audiometry. All seven measurements had excellent inter-observer variability, with average-measure ICC ranging from 0.92 to 0.98. There was no statistically significant correlation between the radiologic degree of aqueduct enlargement and severity of hearing loss using any of the seven measurements; ROC analyses revealed areas under the curves ranging from 0.57 to 0.73. Optimal accuracy was obtained with a threshold of 1.75 mm as measured at the aqueductal aperture in the P€oschl plane, with sensitivity of 0.75 and specificity of0.63. Although the radiologic measurement may not serve as a reliable tool for assessing severity of EVA, P€oschl plane reformatting has proven to be better than conventional axial acquisition plane for identifying patients with clinically significant hearing loss. 相似文献

In the USA, partner non-monogamy is reported to be more common among African American women than White women and may contribute to African American women’s increased risk for HIV and other sexually transmitted infections (STIs). Few studies have explicitly and comprehensively described the protective behaviours that African American women employ with non-monogamous partners to reduce their HIV risk. We conducted interviews to examine protective behaviours among 11 African American women aged 18–24 years who perceived that a partner in the preceding 12 months had another sex partner. Participants described three types of partnerships with 29 non-monogamous men; these partnerships clustered into three categories. Narrative analysis revealed an overall paucity of protective behaviours with non-monogamous partners. Protective behaviours (i.e. communication and condom use) were informed by partnership type, rather than perceptions of non-monogamy. There were few instances in which partner non-monogamy motivated women to terminate sex partnerships. Rather, these decisions were often motivated by changes in other relationship dynamics. To address HIV/STI risk related to partner non-monogamy, HIV prevention strategies for young African American women should emphasise the importance of condom use in all non-marital partnership types. Interventions where testing is available may be effective for women who frequently test for HIV/STIs but do not use condoms. 相似文献
