Is the Metronome-Paced Tachypnea Test (MPT) Ready for Clinical Use? Accuracy of the MPT in a Prospective and Clinical Study.

Background: A simple technique to measure dynamic hyperinflation (DH) in patients with chronic obstructive pulmonary disease (COPD) is the metronome-paced tachypnea test (MPT). Earlier studies show conflicting results about the accuracy of the MPT compared to cardiopulmonary exercise testing (CPET).

Objectives: The focus was to investigate the diagnostic accuracy of MPT to detect DH in a prospective and clinical study.

Treatment of epistaxis without the use of nasal packing, a patient study.

We questioned how many patients with epistaxis can be treated by cautery without the use of nasal packing, as cautery is more effective and efficient. To investigate this, we performed a retrospective study of a cohort of 418 patients with epistaxis who presented to one ENT consultant at the ENT department of Medisch Centrum Leeuwarden (the Netherlands) between 1997 and 2007. Main outcomes were the treatment modality (cautery and/or nasal packing), recurrence of epistaxis and need for hospitalization.
