Tracheostomy is a commonly performed procedure. The aim of this study was to assess professional practice, describe patient characteristics and examine short and long-term outcomes. ⋯ Young patients weaning from mechanical ventilation were more likely to receive a tracheostomy. More than half died during the first year. Patients discharged from ICU with a tracheostomy tube in place had higher mortality rate.

Vocal cord dyskinesia or vocal cord dysfunction (VCD) is characterized by intermittent abnormal adduction of the vocal cords leading to airflow limitation at the level of the larynx, in the absence of local organic disease. It may occur in isolation or in association with asthma. The pathophysiology is complex and poorly understood. Wheeze, stridor or apparent upper airway obstruction are the most common symptoms. It occurs in a wide age range, more commonly in women, and diagnosis is often delayed and leads to unnecessary treatments (intubation, tracheostomy and high dose steroids). ⋯ VCD remains under-appreciated and misdiagnosed, often by mimicking asthma with which it can be associated. A delayed diagnosis by emergency specialists, pulmonologists and ear nose and throat surgeons leads to unnecessary treatments and morbidity before specific therapy can be given.

Patients with COPD frequently have lower strength and endurance in their lower limbs compared to healthy subjects and evaluation of their quadriceps strength is recommended in practice. The handheld dynamometer has been validated and is easy to use for this measurement but its reproducibility has never been studied for endurance evaluation and only poorly for strength. The objective of this study was to estimate the inter and intra-operator reproducibility of maximal voluntary strength and endurance measurements of the quadriceps with a handheld dynamometer in patients with COPD. ⋯ The handheld dynamometer allows an excellent inter and intra-operator reproducibility for the measurement of quadricipital maximal voluntary strength and a correct to excellent reproducibility for the measurement of quadricipital endurance. This tool may be used for the evaluation of quadriceps strength in clinical practice in COPD patients, particularly during rehabilitation.
