AbstractBackgroundFactors predicting locoregional relapse after surgery for oropharyngeal squamous cell carcinoma (SCC) were identified in the pre‐human papillomavirus (HPV) era. We examined whether traditional indications for adjuvant radiotherapy (RT) or adjuvant chemoradiotherapy (CRT) still correlate with locoregional relapse in HPV‐positive patients after transoral robotic surgery (TORS).MethodsRetrospective review of oropharyngeal SCC cases identified patients with HPV‐positive tumors who did not receive adjuvant therapy after TORS despite intermediate or high‐risk features.ResultsMedian follow‐up was 26.7 months (range, 4.9–73.1 months). Five of 25 eligible patients (20%) relapsed at a median 4.8 months (range, 3.2–7.8 months). Two of 18 (11%) intermediate and 3 of 7 (43%) high‐risk patients relapsed. Kaplan–Meier 2‐year locoregional relapse‐free survival estimates for intermediate and high‐risk patients were 88% and 57% (p = .078), respectively.ConclusionTraditional indications for adjuvant RT or CRT were associated with high risk of locoregional relapse in HPV‐positive patients treated with TORS alone. © 2015 Wiley Periodicals, Inc.

Background Nasal congestion and/or obstruction represents a prevalent and extensively studied problem. No published research exists that describes the impact of nasal hair (vibrissae) on nasal obstruction. Objective To assess the impact of nasal vibrissae on subjective and objective measurements of nasal obstruction. Methods In this prospective study, 30 healthy participants without nasal symptoms were assessed for baseline vibrissae density and were treated with a topical decongestant. The subjects were then asked to subjectively assess nasal breathing by using four questions from the Nasal Obstruction Symptom Evaluation instrument before undergoing rhinomanometry. Nasal vibrissae were then trimmed, and the participants repeated the subjective and objective assessments. Pre- and postintervention outcomes, including symptom scores, nasal airflow, and resistance, were compared by using statistical analysis. Results Statistically significant improvement was noted in subjects’ nasal airway specific symptom scores and in objective measurements of their nasal airway. Patients with moderate or many vibrissae at baseline were noted to have greater likelihood of improvement in subjective and objective obstruction assessments than patients rated with few. Conclusion In these 30 subjects, statistically significant improvement occurred in both subjective and objective assessments of nasal obstruction, particularly in patients with greater density of vibrissae. These findings support further study of the potential benefit of the reduction of vibrissae density in some patients with nasal obstruction.

ObjectiveAssess human papilloma virus (HPV) transcriptional activity in inverted Schneiderian papillomas (IPs).Study DesignCase series with chart review.SettingAcademic tertiary care center.Subjects and MethodsRetrospective clinicopathologic review of 19 cases of IP in patients undergoing surgical excision from 1995 to 2013 at Mayo Clinic in Rochester, Minnesota. Surgical pathology archival material was histopathologically reviewed using hematoxylin and eosin–stained slides. Formalin‐fixed, paraffin‐embedded material from each case was evaluated for p16 expression using immunohistochemistry as well as HPV DNA and E6/E7 messenger RNA (mRNA) transcription using polymerase chain reaction (PCR) and in situ hybridization (via RNAscope technology), respectively.ResultsEight patients were female (42%), with an average age of 53 years (range, 23‐82 years). Three demonstrated malignancy, and 5 subsequently recurred. Average follow‐up was 49 months (range, 0‐200 months), and 1 patient died from squamous cell carcinoma arising from the IP. RNAscope detected HPV mRNA transcripts exclusively within IP in 100% of cases; however, in 11 patients (58%), less than 1% of cells exhibited transcriptional activity. Only 2 of 19 cases (11%) demonstrated mRNA activity in 50% or more cells. HPV DNA was detected in only 2 specimens by PCR.ConclusionsThis study reveals wide prevalence but limited transcriptional activity of HPV in IP. No correlation between HPV transcriptional activity and progression, recurrence, or malignant transformation was identified. These data suggest that transcription of HPV may contribute to the pathogenesis of IP, but prospective data are needed to definitively demonstrate this connection. These results also suggest that RNAscope may be more sensitive than PCR in detecting HPV activity in IP.
