Shoulder surface temperature and bone scintigraphy findings in patients with rotator cuff tears.

Background: Complex regional pain syndrome (CRPS) is one of the serious complications after surgical treatment of a rotator cuff tear. Both a measurement of body surface temperature and bone scintigraphy have been used as diagnostic tools for the early phase of CRPS.Unfortunately, few studies have been carried out that applied these methods to the patients after rotator cuff repair.

Changes with time in skin temperature of the shoulders in healthy controls and a patient with shoulder-hand syndrome.

Background: Abnormal skin temperature in the shoulder is caused by various diseases. A thermography is unable to capture temperature changes over time. In contrast, a Thermocron is an effective measuring device to monitor temperature changes over time.

Photomodulation of ionic interaction and reactivity: reversible photoconversion between imidazolium and imidazolinium.

An interconversion system between imidazolium and imidazolinium has been proposed for the first time. Imidazolium and imidazolinium cations exhibit different reactivity due to the difference in the aromaticity and charge localization structure, which is successfully controlled by means of photoirradiation in the present system. A 4,5-dithiazolylimidazolium salt was prepared and studied as a new class of photochromic materials modulating electrostatic interactions and chemical reactivities.

Neglected irreducible dislocation of the interphalangeal joint of the great toe: a case report.

Irreducible dorsal dislocation of the interphalangeal joint of the great toe is rare. We report a case of a 58-year-old man with an irreducible interphalangeal joint of the great toe that had been untreated for 4 years. The mechanism of this injury was thought to be a combination of axial loading with a hyperextension force when the patient hit his great toe against a pipe.

Decreased sensitivity of distal nephron and collecting duct to parathyroid hormone in pseudohypoparathyroidism type I.

Parathyroid hormone (PTH) transiently increases urinary excretion of the lysosomal enzyme, N-acetyl-beta-D-glucosaminidase, which is distributed mainly in proximal tubules. The response is reduced in pseudohypoparathyroidism (PHP) type I, which is characterized by target-organ resistance to PTH. Evidenced by normal calcium resorption, distal tubule sensitivity to PTH has been believed to be normal in this disorder.
