Repair of Auricular Defects.

Repairing defects of the auricle requires an appreciation of the underlying 3-dimensional framework, the flexible properties of the cartilages, and the healing contractile tendencies of the surrounding soft tissue. In the analysis of auricular defects and planning of their reconstruction, it is helpful to divide the auricle into subunits for which different techniques may offer better functional and aesthetic outcomes. This article reviews many of the reconstructive options for defects of the various auricular subunits.

Concordant Oral and Vaginal Human Papillomavirus Infection in the United States.

IMPORTANCE: Human papillomavirus (HPV) is a common infection in adults, with tropism for sites in the head and neck and the genital tracts. To date, few studies have addressed concurrent infection in these sites. OBJECTIVE: To understand the prevalence, characteristics, and concordance of HPV infections in the oral and vaginal regions. DESIGN, SETTING, AND PARTICIPANTS: This study was a retrospective analysis of cross-sectional survey data from the National Health and Nutrition Examination Survey, 2009-2012. The database was reviewed for all women aged 18 to 69 years with available oral and vaginal HPV DNA screening data. The study was performed from August 1, 2014, to November 1, 2014. Data analysis was performed from November 1, 2014, to June 30, 2015. MAIN OUTCOMES AND MEASURES: Logistic regression models were constructed to identify factors associated with infection. Covariates for multivariate analysis included age, income to poverty ratio, number of prior sexual partners, number of prior oral sex partners, and having recent oral sex partners. Dual infection was defined as having an infection of any serotype in both the oral and vaginal HPV regions. Concordant infection was defined as an infection of matching serotype in both locations. RESULTS: A total of 3463 women were identified (mean [SD] age, 37.5 [12.1] years). Racial distribution was 1341 white (38.7%), 786 black (22.7%), 554 Mexican American (16.0%), 378 other Hispanic (10.9%), and 404 self-identified as other (11.7%). Vaginal HPV infection was present in 1586 (45.2%) and oral HPV infection in 141 (4.1%). Dual infection was identified in 107 (3.0%) of all patients, and concordant infection was observed in 41 (1.1%). The prevalence of dual infection was 75.9% in those with oral infection and 6.8% in those with vaginal infection. On multivariate analysis, age (30-50 years) and higher income to poverty ratios had negative associations with dual and concordant infections. A new sexual partner within the last year was positively associated with dual infection (odds ratio, 2.28; 95% CI, 1.03-5.02; P = .04). More than 2 oral sex partners in the past year was positively associated with concordant infection (odds ratio, 3.43; 95% CI, 1.06-11.06; P = .04). CONCLUSIONS AND RELEVANCE: This analysis reveals the importance of several demographic factors (age and socioeconomic status) and behavioral factors (oral sex practices) in the development of dual and concordant HPV infection in women. Notably, other sexual behaviors, other sexually transmitted infections, sexual orientation, and number of lifetime sexual partners did not demonstrate any significant associations. Women with multiple oral sex partners and oral HPV infection have a high likelihood of having concurrent vaginal HPV infection.

Predictors of high-risk and low-risk oral HPV infection in the United States.

OBJECTIVES/HYPOTHESIS: Determine predictors of high-risk and low-risk oral HPV infection in the United States. STUDY DESIGN: Retrospective analyses of National Health and Nutrition Examination Survey cross-sectional data of U.S. population from 2009 to 2012. METHODS: Database queried for subjects aged 18 to 69 with oral rinse human papillomavirus (HPV) DNA data. Logistic regression identified factors associated with high-risk and low-risk infection. Covariates included age, gender, ethnicity, income-to-poverty (IP) ratio, sexual orientation, human immunodeficiency virus infection, other sexually transmitted infections, lifetime sexual partners, and lifetime oral sex partners. RESULTS: In total, 9,256 subjects were identified with mean age of 42.1 years. Oral HPV infection was present in 8.1% (N = 747); 55.7% were high-risk and 55.3% were low-risk types, including 11% with both. Oral infection had a negative association with female gender (odds ratio [OR] 0.3, P < 0.001), IP ratio ≥ 3 (OR 0.7, P = 0.02), and one lifetime oral sex partner (OR 0.7, P = 0.03). Increasing oral sex behavior (6-21+ lifetime partners) was positively associated with oral HPV (OR 1.4-3.0, P = 0.03). Low-risk infection had negative associations with female gender (OR 0.4, P < 0.001) and non-Hispanic white ethnicity (OR 0.6, P = 0.02), IP ratio ≥ 3 (OR 0.6, P = 0.01), and positive association with > 20 sexual partners (all sex OR 1.7, P = 0.04; oral sex OR 1.9, P = 0.02). Predictors of high-risk HPV infection included male gender and increasing oral sex partners. CONCLUSION: Increasing oral sex partners is positively associated with oral HPV infection; female sex and higher socioeconomic class are negatively associated. The risk-factor profiles for high-risk and low-risk HPV types are distinct, with similar trends related to sexual behaviors. LEVEL OF EVIDENCE: 4. Laryngoscope, 126:1365-1372, 2016.

Comparison of two nasal cell collection methods in determining cyclic adenosine monophosphate levels and its association with olfaction: A feasibility study.

Cyclic adenosine monophosphate (cAMP) is a second messenger that may be associated with olfactory function. No known studies have compared existing collection methods for determining nasal cAMP levels. This is a prospective study comparing the comfort and reliability of the nasal curette and cytobrush. A secondary outcome collected for feasibility testing was characterizing the association between cAMP and olfactory function. We enrolled 19 normal olfaction and 10 olfactory dysfunction subjects. Olfaction was measured by the University of Pennsylvania Smell Identification Test. Two samples were obtained from each nasal cavity at the initial visit and at 1 week follow-up. Comfort was measured by a visual analog scale (VAS). cAMP levels were determined by an enzyme immunoassay. For the curette and cytobrush, mean VAS scores were 0.3 and 0.7 cm (p = 0.48). Intraclass correlation coefficients were 0.81 (curette) and 0.65 (cytobrush) for the initial visit and 0.64 and 0.54 between the initial and follow-up visit. Using the curette, mean cAMP was 537 and 480 fmol/(mg/mL) for the normal and dysfunction cohorts (p = 0.18). Using the cytobrush, cAMP was 505 and 477, respectively (p = 0.65). The curette and cytobrush are both comfortable and reliable collection methods for determining nasal cAMP levels.

Maternal medical and behavioral risk factors for congenital diaphragmatic hernia.

PURPOSE: Maternal factors contributing to the etiology of congenital diaphragmatic hernia (CDH) remain unclear. We hypothesized that specific maternal medical conditions (pregestational diabetes, hypertension), and behaviors (alcohol, tobacco) would be associated with CDH. METHODS: We conducted a population-based case-control study using Washington State birth certificates linked to hospital discharge records (1987-2009). We identified all infants with CDH (n=492). Controls were randomly selected among non-CDH infants. Maternal data were extracted from the birth record. Logistic regression was used to adjust for covariates. RESULTS: Cases and controls were generally similar regarding demographics, although CDH infants were more likely to be male than controls (58.5% vs. 52.5%). Isolated and complex (multiple-anomaly) CDH had similar characteristics. Each of the exposures of interest was more common among case mothers than among control mothers. In univariate analysis, alcohol use, hypertension, and pregestational diabetes were each significantly associated with the outcome. After multivariate adjustment, only alcohol use (OR=3.65, p=0.01) and pregestational diabetes (OR=12.53, p=0.003) maintained significance. Results were similar for both isolated and complex CDH. CONCLUSIONS: Maternal pregestational diabetes and alcohol use are significantly associated with occurrence of CDH in infants. These are important modifiable risk factors to consider with regard to efforts seeking to impact the incidence of CDH.
