Stridor in Parkinson's disease: a case of 'dry drowning'?
(1) To present a rare case of stridor secondary to prolonged laryngospasm in a patient with Parkinson's disease, and (2) to review the literature on stridor in Parkinson's disease. ⋯ Laryngospasm can be triggered in Parkinson's disease by excessive secretions entering the larynx. The mechanism is similar to 'dry drowning'. Treatment focuses on reducing secretions. The use of botulinum toxin to reduce spasm is inappropriate in this situation. This case emphasises the importance of recognising different causes of stridor in Parkinson's disease patients, as this affects management.

Over the past 20 years, jet ventilation techniques have been developed to enable safe and controlled microlaryngoscopy and the accurate treatment of laryngeal pathology. This study examined how advances in jet ventilation tube design have facilitated safe endolaryngeal surgery. ⋯ Subglottic jet ventilation facilitates safe airway management during microlaryngeal and laser laryngeal surgery.

Multicenter Study
The 14-item Paediatric Throat Disorders Outcome Test: a valid, sensitive, reliable, parent-reported outcome measure for paediatric throat disorders.
We modified and abbreviated a pre-existing research questionnaire, the Tonsil and Adenoid Health Status Instrument, to make it suitable for rapid completion as a disease-specific, health-related quality of life research tool for children with tonsil and adenoid disease in the UK. We determined the main psychometric properties of the resulting 14-item Paediatric Throat Disorders Outcome Test. ⋯ The 14-item Paediatric Throat Disorders Outcome Test is an appropriate, disease-specific, parent-reported outcome measure for children with throat disorders, for which we have demonstrated internal consistency, reliability, responsiveness to change and two forms of construct validity.

We report a case of a multinodular goitre developing in a lingual thyroid. ⋯ Lingual thyroids have an incidence of one in 3,000 to 10,000. There has not previously been a reported case of such an ectopic gland undergoing multinodular changes and presenting in later life.

(1) To compare audiometric parameters in patients with vestibular schwannoma and in those with asymmetric hearing loss from other causes; and (2) to assess proposed screening criteria by comparing published protocols. ⋯ As regards vestibular schwannoma screening protocols, the best compromise between sensitivity and screening rate was offered by a criterion comprising either: (1) > or =20 dB asymmetry at two neighbouring frequencies, or unilateral tinnitus, or (2) > or =15 dB asymmetry at two frequencies between 2 and 8 kHz.
