OBJECTIVES The purpose of this study was to compare the thickness of the hip capsule in patients with surgical hip disease, either with cam-femoroacetabular impingement (FAI) or non-FAI hip pathology, with that of asymptomatic control hips. METHODS A total of 56 hips in 55 patients underwent a 3Tesla MRI of the hip. These included 40 patients with 41 hips with arthroscopically proven hip dise...

Obscure gastrointestinal bleeding is a common disorder and may account for as many as 5% of all gastrointestinal hemorrhages. It is often caused by lesions in the small intestine, which were very complicated to examine prior to the advent of wireless capsule endoscopy. Here we present the case of a 31-year-old woman with obscure gastrointestinal bleeding as a complication of radiation enteritis...

We demonstrated fast three-dimensional transmission terahertz computed tomography by using real-time line projection of intense terahertz beam generated by optical rectification in lithium niobate crystal. After emphasizing the advantage of intense terahertz pulse generation for two-dimensional spatio-temporal terahertz imaging, peak-to-peak amplitudes of pulsed terahertz electric field have be...

Chronic anterior shoulder instability due to structural failure of the subscapularis muscle and the anterior capsule is a rare and challenging diagnosis for surgeons to manage because poor-quality capsular, labral, and rotator cuff tissue often limits effective treatment options. If primary repair is not possible because of retraction and poor tissue quality, reconstruction with an allograft or...

Currently there are few parameters that are used to compare the efficiency of different methods of cancerous prostate surgical removal. An accurate assessment of the percentage and depth of extra-capsular soft tissue removed with the prostate by the various surgical techniques can help surgeons with determining the appropriateness of different surgical approaches. Additionally, an objective ass...

OBJECTIVES   We describe our technique and experience with subcapsular placement of the Interstim (Medtronic, Minneapolis, MN, USA) pulse generator in cases of revision for implant site pain. METHODS   The pulse generator and electrode are carefully exteriorized and the floor of the capsule is incised. The system is placed beneath the floor of the original capsule, which then becomes the roof...

In this immunohistochemical study we investigate the presence of vasoactive intestinal peptide (VIP) and neuropeptide Y (NPY) during embryonic development in the sheep pineal gland. We use ten ovine embryos at different stages of development (117 to 150 days of prenatal development). The VIP positive fibers were observed along the blood vessels, entering the pineal gland through the pineal caps...
