The low incidence of positive BAL in the CAP group supports using BAL only for particularly severe, selected cases. Mortality was very high in the immunocompromised patients. In the light of our personal experience, BAL is most useful in the diagnosis of pneumonia in the group of patients with VAP.

Background:Hip arthroscopy is considered a safe procedure, considering the relatively low rate of complications. Despite several complications have been described following this surgical procedure, the present event has not yet been described. The purpose of the present study is to report an unpublished complication following hip arthroscopy, after reviewing 162 hip arthroscopies and finding iliotibial band syndrome (ITBS) in the knee during followup.Materials and Methods:A retrospective review of 162 hip arthroscopies performed between September 2007 and June 2011 was carried out, evaluating patients who presented ITBS during followup. Indication for hip arthroscopy was failure of conservative treatment in patients with symptomatic femoroacetabular impingement.Results:During a minimum followup of 2 years, nine patients (5.5%) developed ITBS. All patients were diagnosed with ITBS within the first 45 postoperative days. Conservative treatment was successful in 6 patients while 3 had to undergo surgery. The increased internal rotation, synovitis and increased adduction of the hip can be attributed as predisposing factors to the development of ITBS.Conclusions:This is a newly described observation within followup of hip arthroscopy. These findings may help orthopedic surgeons when planning rehabilitation after hip arthroscopy, including stretching exercises to prevent this syndrome.
