OBJECTIVE To determine whether levels of PH-20, a hyaluronidase similar to that found in human sperm, are elevated in laryngeal cancer tissue. DESIGN In this case-control study. reverse transcription polymerase chain reaction was used to measure levels of PH-20 messenger RNA in tissue taken from laryngectomy specimens. SETTING A university medical center. PATIENTS We compared tissue sampl...

Abstract Expressing syllable weight by moras leads to two problems. First, there are languages, such as Wolof, with long vowels and geminates, which both make a bimoraic, but where only vowels, not count heavy for stress. Second, languages in closed syllables light stress, segmental modifications (laryngeal metathesis Cayuga degemination Chugach Alutiiq). It is argued that two-layered mora mode...

.. Objectives: The aim of our study is to determine the incidence of complications when using Laryngeal mask airway and compare it with endotracheal tube intubation, during administration of low flow anesthesia. Study Design: A randomized control trial. Period: 3 months from February 2015 to April 2015. Setting: Tertiary Care Hospital in Karachi Pakistan. Materials and Methods: The study popula...

BACKGROUND The human respiratory airway undergoes dramatic growth during infancy and childhood, which induces substantial variability in air flow pattern and particle deposition. However, deposition studies have typically focused on adult subjects, the results of which cannot be readily extrapolated to children. We developed models to quantify the growth of human nasal-laryngeal airways at earl...

BACKGROUND The ProSeal is a wire-reinforced laryngeal mask airway with an additional drain tube that leads to the distal tip of the laryngeal cuff. The design should improve the seal with the larynx. METHODS The ProSeal and classic laryngeal mask airways were compared in 180 patients in a randomized crossover study. Patients were anaesthetized without neuromuscular blocking drugs. RESULTS T...

  Primary non-Hodgkin lymphoma of the larynx is rare, accounting for less than 1% of all laryngeal neoplasms. Fewer than 100 cases have been reported in the literatureand to our knowledge this may be the first reported case of laryngeal non Hodgkin lymphoma presented with hoarseness, aortic aneurysm, hepatitis B and skin rashes.

Background & Aims: Surgeons are not willing to participate in thyroid surgeries due to dangerous, although rare, complications of the procedure. Post thyroidectomy complications are divided in early and late onset; hypocalcemia, bleeding, thyroid storm and recurrent laryngeal nerve (RLN) injury are the most important ones. This study was performed to compare the frequency of recurrent laryngeal...

Laryngopharyngeal or gastroesophageal reflux is associated with laryngeal airway hyperreactivity (LAH), but neither the cause-effect relationship nor the underlying mechanism has been elucidated. Here we established a rat model with enhanced laryngeal reflex reactivity induced by laryngeal acid-pepsin insult and investigated the neural and hydroxyl radical (*OH) mechanisms involved. The larynge...

Introduction:Dystonia is a disorder of movement caused by various etiologies. Laryngeal dystonia is caused by the spasm of laryngeal muscles. It is a disorder caused by vocal fold movement in which excessive adduction or abduction of the vocal folds occurs during speech. The pathophysiology of this type of dystonia is not fully known. Some researchers have suggested that basal ganglia structure...
