The aim of this study was to determine whether skin temperature measurement by digital thermography on hands and feet is useful for diagnosis of Raynaud's phenomenon (RP). Fifty-seven patients with RP (primary RP, n = 33; secondary RP, n = 24) and 146 healthy volunteers were recruited. After acclimation to room temperature for 30 min, thermal imaging of palmar aspect of hands and dorsal aspect ...

OBJECTIVE To evaluate horseshoe characteristics and high-speed exercise history as risk factors for catastrophic musculoskeletal injury in Thoroughbred racehorses. ANIMALS 377 horses (37,529 race starts). PROCEDURES Shoe characteristics included material, toe grab height, heel traction device, pads, and rim shoes. Racing variables were obtained from a computerized database. Forty-three hors...

With lumbar epidural anaesthesia, big toe skin temperature increases and is associated with a compensatory decrease of thumb temperature. The purpose of the present study was to examine whether thumb-big toe temperature differences were affected by age. Following the attachment of temperature probes at the digital pad of the right big toe and the right thumb, lumbar epidural anaesthesia at L2/3...

Background: The effects of position and exercise on pulse wave distribution across a healthy, compliant arterial tree are not fully understood. We studied the effects of exercise and position on the pattern of pulse arrival times (PATs) in healthy volunteers. Moreover, we compared the pulse arrival time ratios to the respective distance ratios between different locations. Methods: Thirteen youn...

RATIONALE Chondroid syringoma (CS) occurs mostly on the face and neck, and rarely occurs in the toe. Malignant CS is invasive, grows quickly, and has a high recurrence rate. The presence of a bilobed CS in 1 toe has never been reported in the literature. PATIENT CONCERNS A 72-year-old male patient presented with a mass in a third toe of his right foot. The mass had slowly grown in 2 years. He...

The standard measurement of pulse wave velocity (PWV) is restricted by the need for simultaneous tonometry measurements requiring two technicians and expensive equipment, limiting this technique to well-resourced settings. In this preliminary study, we compared a simplified method of pulse wave detection from the finger and toe to pulse wave detection from the carotid and radial arteries using ...

OBJECTIVE Clawing of the toes in the diabetic neuropathic foot is believed to be caused by muscle imbalance resulting from intrinsic muscle atrophy. However, experimental data that support this mechanism are lacking. The aim of this study was to evaluate this hypothesis using magnetic resonance imaging (MRI). RESEARCH DESIGN AND METHODS In 20 neuropathic diabetic patients, 10 with claw toe de...

A 13-year-old boy presented with sudden-onset give-away weakness, nonanatomic sensory loss, and posturing of the right foot followed by episodic left leg tremor, relatively unchanged for 14 months prior to this evaluation. The right first toe was fixed in extension; the others in flexion. Although there was resistance to passive plantar flexion, such movement occurred spontaneously upon forced ...

The purpose of this study was to compare the haemodynamic effects of intra-arterial and intravenous prostaglandin E1 (PGE1) both injected and infused into ischaemic legs. Continuous intra-arterial infusion of PGE1 induced a significantly greater increase in skin temperature and blood flow than did intravenous drip infusion. Furthermore, intra-arterial infusion caused no steal phenomenon in the ...

INTRODUCTION Traumatic loss of thumb at the carpometacarpal (CMC) joint level is very disabling to an individual. Pollicisation is the recommended technique of reconstruction for loss of thumb at this level. On occasions, injury to the rest of the hand or amputation of additional fingers may make pollicisation an impossible option. Microsurgical transfer of second toe is an option in such situa...
