COMPLICATIONS IN HIP ARTHROSCOPY.

Objectives: To determine the prevalence of complications in a series of consecutive cases of hip arthroscopy; to assess the progression of the sample through a learning curve; and to recognize the causes of complications in arthroscopic hip operations.

Method: 150 consecutive cases that underwent hip arthroscopy between May 2004 and December 2008 were evaluated. The complications encountered were classified in three ways: organic system affected, severity and groups of 50 consecutive cases.

Is gaze-dependent tonometry a useful tool in the differential diagnosis of Graves' ophthalmopathy?

Background: A rise in intraocular pressure (IOP) in upgaze is regarded as a diagnostic sign in Graves' ophthalmopathy (GO). However, the question of erroneous IOP measurement due to applanation carried out on the peripheral cornea has never been addressed.

Methods: In 22 healthy volunteers, as well as in 51 GO patients, applanation tonometry was performed in the primary position of gaze and at 20 degrees of upgaze.
