To determine the rate of manipulation under anaesthesia (MUA) following distension arthrogram for adhesive capsulitis of the shoulder. Thirty-nine patients (42 shoulders) between 1998 and 2004 were treated with distension arthrogram for adhesive capsulitis diagnosed by the clinical picture of progressive pain and stiffness. Capsular disruption into the subscapular bursa was demonstrated in 40 of the 42 shoulders (95%). Thirty-seven of 42 (88%) shoulders were painfree following distension arthrogram. 15 of 42 (36%) shoulders underwent MUA following distension arthrogram for stiffness although 10 of these (67%) were painfree. Prior to distension arthrogram, the range of external rotation (ER) was no different between those that had MUA and those that did not (P = 0.36). The improvement in ER was 33% (P = 0.28) in those that had MUA and 50% (P = 0.001) in those that did not. The only complication was a vasovagal episode during the procedure. Distension arthrogram can be used as a therapeutic procedure for achieving symptomatic pain relief in the majority of adhesive capsulitis and decrease the rate of MUA of the shoulder.
The uroguanylin system is a newly discovered endocrine/paracrine system that may have a role in the regulation of salt balance, appetite and gut health. The precursor pro-uroguanylin is predominantly synthesized in the gut, although there may be other sites of synthesis, including the kidney tubules. Products from pro-uroguanylin may mediate natriuresis following oral consumption of a salt load through both GC-C (guanylate cyclase C)-dependent and -independent mechanisms, and recent evidence suggests a role in appetite regulation. Local paracrine effects in the gut through GC-C stimulation may have tumour-suppressing actions through the regulation of cell proliferation and metabolism. Although most information on this system has been derived from knockout models, recent human studies have indicated possible roles in heart failure and renal failure. An improved understanding of the nature of its natriuretic, appetite and tumour-suppressing actions may facilitate the discovery of new therapies for heart failure, obesity and cancer prophylaxis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
