An unknown primary should be diagnosed only after a complete head and neck examination, flexible endoscopy, and CT or MRI. PET/CT performed prior to panendoscopy will increase the diagnostic yield in the unknown head and neck primary population, leading to more targeted, and less morbid, treatment.

BackgroundIn Dutch ambulance practice, failure or inability to intubate patients with altered oxygenation and/or ventilation leaves bag-valve mask ventilation as the only alternative, which is undesirable for patient outcome. A novel Laryngeal Mask Airway Supreme (LMA-S) device may be a suitable alternative.AimTo evaluate the effectiveness and suitability of the LMA-S for emergency medical services in daily out-of-hospital emergency practice.MethodsAfter a period of theoretical and practical training of ambulance paramedics in the use of the LMA-S, prospective data were collected on the utilisation of LMA-S in an observational study. Procedures for use were standardised and the evaluation included the number of direct intubation attempts before using LMA-S, attempts required, failure rate and the adequacy of ventilation. Data were analysed taking patient characteristics such as age and indication for ventilatory support into account.ResultsThe LMA-S was used 50 times over a period of 9 months (33 involving cardiorespiratory arrest, 14 primary and three rescue). The LMA-S could be applied successfully in all 50 cases (100%) and was successful in the first attempt in 49 patients (98%). Respiratory parameters showed adequate oxygenation. All paramedics were unanimously positive about the utilisation of LMA-S because of the easiness of the effort of insertion and general use, and emphasised its value as a useful resource for patients in need.ConclusionsEnsuring ventilation support by using LMA-S by paramedics in prehospital emergency practice is safe and effective.

BackgroundTrans-nasal flexible fibre-optic laryngoscopy (TFFL) is an essential skill for otolaryngologists. There is evidence to suggest that simulators help residents acquire procedural skills. The objective of this study was to examine the effect of simulation on endoscopy skill acquistion.MethodsA randomized controlled trial was conducted utilizing medical students and junior residents with limited experience in TFFL. Learners all performed a baseline endoscopy and were then randomized to receive either 45 minutes of simulation training or not. Following this, a second endoscopy was performed. Time to adequate visualization of the glottis, the percentage of time adequate visualization of the airway was maintained, and the number of collisions with mucosa were analyzed. Qualitative assessments were also obtained from the learner, patient, and staff laryngologist.ResultsTime to adequate visualization of the glottis and the number of mucosal collisions were significantly less during the second endoscopy, irrespective of the use of simulation (84.8 sec vs. 68 sec, p < 0.01; 5.0 vs. 3.2, p < 0.01, respectively). Analysis using a two-way ANOVA with interaction established that none of the quantitative measures analyzed in this study improved with the addition of simulation.ConclusionImprovements in time to visualization of the glottis and number of mucosal contacts were seen between the first and second endoscopy irrespective of simulator use. No additional benefit was conferred with the use of a low-fidelity simulator.

The TQOL has moderately strong internal consistency, convergence validity, and test-retest reliability. While additional refinement and validation may improve the questionnaire, these initial results are promising and support further development of this tool.

BackgroundOperative endoscopy and flexible fiber-optic in-office tissue biopsy are common techniques to assess suspicious laryngopharyngeal lesions.MethodsThe primary outcome was the delay to the initiation of treatment. Secondary outcomes were delay to biopsy, histopathological diagnosis, and assessment at a multidisciplinary oncology clinic. A retrospective analysis was performed to assess the relative delays between these approaches to biopsy of laryngopharyngeal lesions.ResultsThere were 114 patients in the study cohort; 44 in-office and 70 operative endoscopic biopsies). The mean delay from consultation to biopsy was 17.4 days for the operative endoscopy group and 1.3 days for the in-office group. The mean delay from initial otolaryngology consultation to initiation of treatment was 51.7 days and 44.6 days for the operative endoscopy and in-office groups, respectively.ConclusionIn-office biopsy reduced the time from initial consultation to biopsy. The temporal gains via in-office biopsy did not translate into faster access to treatment. This outcome highlights the opportunity to improve access to treatment for patients with early diagnosis.
