Contribution of four common pulmonary function tests to diagnosis of patients with respiratory symptoms: a prospective cohort study.

Background: Few studies of the diagnostic value of pulmonary function testing are available. We assessed the diagnostic contribution of four basic pulmonary function tests: spirometry, lung volume, airway resistance, and diffusing capacity.

Methods: In this prospective cohort study, we enrolled patients presenting to a pulmonologist with respiratory symptoms but no clear diagnosis from 33 hospitals in Belgium.

Hemoptysis and pulmonary edema in a scuba diver using diclofenac.

Hemoptysis and pulmonary edema associated with nonsteroidal anti-inflammatory drug use is a known condition, but is probably underreported. The mechanisms of induction of pulmonary toxicity are still not well understood. We describe a case of hemoptysis and dyspnea in a scuba diver who was taking diclofenac.

Innervation of the elbow joint: Is total denervation possible? A cadaveric anatomic study.

The aim of this anatomical study was to find out if total denervation of the elbow joint is technically feasible. The endbranches of the brachial plexus of eight fresh-frozen upper arm cadavers were dissected with optical loupe magnification. All major nerves of the upper limb (except the axillary and the medial brachial cutaneous nerve) give some terminal articular endbranches to the elbow.
