Overall, 22 patients with T1b and T2 glottic tumours and more than one year of follow-up were studied. Two experienced observers analysed the recorded videokymographic data. A cross-sectional descriptive design was used. The images showed the vocal vibratory behaviour during sustained /i/ phonation. The vibratory source was supraglottic in 7/22 patients, glottic in 11 and mixed in 4. The mean duration of the glottic cycles extracted from the supraglottic, mixed and glottic vibratory sources was 6.4 ms, 5 ms and 4.6 ms, corresponding to the fundamental frequency (f0) of 188.7 Hz, 200 Hz and 215.7 Hz, respectively. Of the 11 patients with a glottic vibratory source, 4 did not present a closed phase in the glottic cycle. The mean open quotient was 79%, 40% and 63%, for the supraglottic, mixed and gl...

Methods: A total of 21 patients who underwent surgery due to benign tracheal stenosis in our clinic between 2010 and 2017 were retrospectively evaluated. The patients were analyzed in terms of age, gender, surgical indication, surgical approach, comorbidities, length of the trachea resected, postoperative complications, the duration of hospitalization and development of restenosis. Results: Out of 21 patients, 12 were male and nine female. Surgical indication was postintubation tracheal stenosis in 15 patients. The mean age was 39.6 (10-83) and the mean length of resection was 3.33 cm. Collar incision was performed in 16, collar and sternotomy incision in 3, and sternotomy incision in 2 patients. Complication rates were high in patients with comorbidity. Conclusion: Tracheal surgery is mostly applied due to benign disease in addition to the malignant diseases of the tracheal surgery is mostly performed with low rates of morbidity and mortality, and the outcomes are usually satisfactory.

Letters to the Editor discuss material recently published in the Journal. Letters will have the best chance of acceptance if they are received within 8 weeks of an article's publication. Letters to the Editor may be published with a response from the authors of the article being discussed. Discussions beyond the initial letter and response will not be published. Letters submitted pertaining to published Discussions of articles will not be printed. Letters to the Editor are not usually peer reviewed, but the Journal may invite replies from the authors of the original publication. All Letters and Viewpoints are published at the discretion of the Editor. Viewpoints pertain to issues of general interest, even if they are not related to items previously published (such as unique techniques, brief technology updates, technical notes, and so on). Please note the following criteria for Letters and Viewpoints: • Text-maximum of 500 words (not including references) • References-maximum of five • Authors-no more than five • Figures/Tables-no more than two figures and/or one table Authors will be listed in the order in which they appear in the submission. Letters and Viewpoints should be submitted electronically via PRS' enkwell, at www.

The dermal glands of frogs secrete, among other things, antimicrobial peptides. As part of the innate immune system, stressors may affect the production of antimicrobial peptides by dermal glands. The dermal secretions of some salamanders have been examined for their toxic secretions, but little attention has been given to salamander antimicrobial peptides. This study examines the skin from the tail region for the production of antimicrobial peptides in the terrestrial salamander, Plethodon cinereus. Fractions of tail extracts were isolated using cation-exchange chromatography and reverse-phase HPLC. An HPLC fraction eluting at 15.75 min (HPLC run: 30 min, 30-80% acetonitrile/water gradient, Aquapore RP-300 C18 column) showed activity against Staphylococcus aureus but not against Escherichia coli. The antibacterial activity gradually increased over a 4-hr incubation time up to about 85% inhibition of bacterial growth. Lysis of guinea pig red blood cells also increased gradually over a 1-hr time period.

Foram realizadas medidas da altura do labio em fase pre-operatoria, apos o tratamento muscular, apos a simples adesao da pele e apos completada a plastica em Z. Os resultados numericos das medidas realizadas demonstraram que ha um ganho significativo apos a reparacao muscular e tambem apos a plastica em Z, comprovada pelo teste estatistico de t de Student, com nivel de significância de 0,01. O alongamento necessario foi conseguido em todos os casos, atingindo a altura proxima das medidas ideais. Os autores discutem a evolucao das tecnicas cirurgicas empregadas nas queiloplastias, com enfoque especial para a reconstrucao da musculatura da regiao e nas taticas que possibilitam o...
