BACKGROUND Recent literature has demonstrated that the success rates of arthroscopic stabilization of glenohumeral instability deteriorate in patients with an anteroinferior glenoid bone deficiency, also known as the "inverted pear" glenoid. PURPOSE This study was conducted to assess the outcomes of arthroscopic stabilization for recurrent anterior(More)
Right ventricular pseudoaneurysm is a rare complication following repair of Tetralogy of Fallot. Presented are two patients, both with history of Tetralogy of Fallot, successful repair and pseudoaneurysms discovered on symptomatic follow up. Because surgical intervention is often required, the location and characteristics of the pseudoaneurysm are critical(More)
BACKGROUND High-intensity repetitive athletic activities may predispose the brachial plexus to repetitive stretch, compression, and subsequent injury, although painless shoulder weakness is a rare event. PURPOSE The physical examination and electrodiagnostic findings in a series of United States Navy special warfare trainees who presented with acute(More)
A 27-year-old nulligravida active duty U.S. Navy chief petty officer presented with right flank pain and recurrent urinary tract infections without any history of nocturnal sweating or unexplained weight loss. Her physical examination was remarkable for mild right costovertebral angle tenderness and urinalysis showed hematuria. Subsequent computed(More)
A comparison is made between cerebral evoked potentials through the left and right eye by studying the correlation functions between the two visual responses obtained. Two values were retained: the correlation coefficient CO which shows the degree of similarity between the two curves, and the phase displacement D which indicates the duration for which a(More)
Bezoars are conglomerations of indigestible material that become trapped in the gastrointestinal tract. We present a case of an 8-year-old female child diagnosed with a gastric bezoar solely on plain radiography and treated with abdominal surgical exploration and removal. In addition, traditional characteristic radiographic findings and treatment options(More)
PURPOSE The purpose of this study was to describe the anatomic features of the glenoid and labrum for shoulders with and without Kim's lesions, as well as define the sensitivity, specificity, and reliability of magnetic resonance arthrogram for the detection of these lesions and determine the interobserver reliability of Kim's classification for posterior(More)
Carcinoid is a rare lung cancer that typically presents with a relatively indolent clinical behavior. We present the case of a 32-year-old male with progressive respiratory symptoms, which resulted in the diagnosis of typical bronchial carcinoid. This case shows a novel imaging technique for staging a bronchial carcinoid for determination of optimal(More)
