BACKGROUND AND PURPOSE We describe the structural abnormalities in the painful shoulder of stroke survivors and their relationships to clinical characteristics. Method- Eighty-nine chronic stroke survivors with poststroke shoulder pain underwent T1- and T2-weighted multiplanar, multisequence MRI of the painful paretic shoulder. All scans were reviewed by one radiologist for the following abnorm...

When revising failed double-row and suture-bridge rotator cuff repairs medial failures represent a potential feature. In the presence of a compromised healing environment, patch augmentation becomes a logical adjunct from a mechanical and biological point of view. A reproducible step-by-step revision technique is described that reinforces the weak central cuff area with an absorbable synthetic ...

Ideally, interference in neural measurements due to signals from nearby muscles can be completely eliminated with the use of tripolar nerve cuff electrodes, in combination with appropriate amplifier schemes. In practice the cuff departs from its ideal model leading to cuff imbalance. As a result, the output nerve signal of such amplifiers has been widely reported to be degraded by interference,...

The long head of biceps tendon (LHBT) is frequently involved in rotator cuff tears and can cause anterior shoulder pain. Tendon hypertrophy, hourglass contracture, delamination, tears, and tendon instability in the bicipital groove are common macroscopic pathologic findings affecting the LHBT in the presence of rotator cuff tears. Failure to address LHBT disorders in the setting of rotator cuff...

There is documented evidence of the use of Terminalia chebula for various ailments in the Ayurvedic literature. The extract has been shown to possess glucose lowering activity and to improve insulin sensitivity in animal models of type 2 diabetes mellitus. The present study was carried out to study the dose response relationship of this extract in a rat model of metabolic syndrome. Six groups o...

The ability of exercise training to block the generation of hypertension produced by chronic stress in the borderline hypertensive rat was tested. Twenty-three male borderline hypertensive rats, F1 offspring of spontaneously hypertensive and Wistar-Kyoto rats, were divided into three groups. Two groups (8 rats per group) were subjected to 2 hours of daily, predictable, uncontrollable tail shock...

Nitrous oxide (N2O) is an inhalational anesthetic that is frequently used for general anesthesia. While N2O is not sufficient for maintaining general anesthesia if used alone, when used in combination with a volatile inhalation agent, N2O decreases the minimum alveolar concentration (MAC) of the volatile inhalational agent, thereby reducing the amount of the agent required during longer procedu...

STUDY OBJECTIVE The aim of this study was to estimate the cumulative incidence of vaginal cuff dehiscence in robotic-assisted total hysterectomies in our patients and to provide recommendations to decrease the incidence of vaginal cuff dehiscence. METHODS This was an observational case series, Canadian Task Force Classification II-3 conducted at an academic and community teaching hospital. A ...

TO THE EDITOR: I read with great interest the paper of Baserga et al. (1), which describes the effect of uterine artery ligation in the pregnant rat on fetal cyclooxygenase-2 (COX-2) expression and blood pressure. This is an important subject and the study presents interesting results, but I would like to comment on some parts of their study. As nephrogenesis in the rat is a process that contin...
