Pharyngo-esophageal complications of Ryle tube insertion in neonates: management and fate.

Introduction: The following provides clinical reporting of seven neonates with iatrogenic pharyngeal trauma due to forceful untrained use of nasogastric feeding tube. A range of symptoms were observed beginning with excessive frothy secretions culminating in more severe pneumothorax in some. These cases are presented in the context of an exhaustive literature review producing only 50 similar cases worldwide.

The posterior glottis: structural and clinical considerations.

Despite the presence of a number of good publications during the past two decades, the posterior glottis (PG) is still not clearly appreciated in clinical laryngological practice. This study focuses on searching the literature to find out the present day awareness of the PG, as well as highlighting some of its clinical features. The investigation proceeds with two main sections: (1) critical analysis of the literature on the PG during the last 50 years (2) describing the clinical appearance and behavior of the PG in 100 normal subjects.

Laryngeal electromyography: a proposal for guidelines of the European Laryngological Society.

Although recognized as a valuable diagnostic tool for more than 60 years, many laryngologists do not routinely use laryngeal electromyography (LEMG). This may be due to a persisting lack of agreement on methodology, interpretation, validity, and clinical application of LEMG. To achieve consensus in these fields, a laryngeal electromyography working group of European neurolaryngologic experts was formed in order to (1) evaluate guidelines for LEMG performance and (2) identify issues requiring further clarification.

Localization and regulation of aquaporins in the murine larynx.

Conclusion: Expression of aquaporins (AQPs) in the vocal folds and the parasympathetic regulation of AQPs in the laryngeal glands may be important for controlling laryngeal secretion and vocal fold hydration. These findings are thought to be an initial step towards understanding potential mechanisms of water flow through the vocal fold surface.

Objectives: Lubrication of the vocal folds is important for phonation and laryngeal defense.
