Close monitoring of patients for delayed hyponatremia post-transsphenoidal surgery

he incidence of delayed hyponatremia is 16-28% and usually accounts for unplanned readmission of the patient within 30 days after transsphenoidal surgery. One of the surrogate measures of quality of care adopted by the government and regulatory agencies is 30-day...

Tinnitus in patients on therapy with PPI and in PPI non–users

Tinnitus is a chronic and debilitating condition and approximately 10% of the population is afflicted. A myriad of pharmacological treatments for tinnitus are available but only a few controlled studies have shown positive results. The relationship between proton pump inhibitors...

An overview of human factors in ENT and anaesthesia

James Bates and Chris Frerk are both passionate about how human factors science can improve safety in healthcare and have co-authored this article describing how communication, ergonomics and other non-technical skills are making operating theatres safer. There is no doubt...

Surgical management of sleep disordered breathing

Snoring and sleep-disordered breathing are often described as multi-level problems, and different surgical procedures are required to treat the various sites of airway narrowing and/or collapse. Jonathan Hobson gives us an eloquent run-through the various options available to the ENT...

The structure and function of DNA

DNA structure and replication Genetic information within multicellular organisms, including man, is stored in molecules of deoxyribonucleic acid (DNA), which reside within the chromosomes of each cell nucleus. A DNA molecule consists of two very long chains, or strands, of...

Prospective evaluation of quality of life in the flaccid

Flaccid midface paralysis causes nasal valve collapse due to the lack of tonic muscular support. This causes both external nasal valve narrowing and collapse during inspiration. Correction of the nasal valve is performed in functional rhinoplasty. However, these procedures do...

The effects of hormonal changes across menstrual cycle on high frequency auditory thresholds
