OBJECTIVE To evaluate the frequency and the clinical characteristics of distal extremity swelling with pitting edema in patients with psoriatic arthritis (PsA). METHODS This was a case-control study of consecutive outpatients with PsA (old and new diagnosis) observed over a 3-month period in three secondary referral centers in Italy. As controls we used the two consecutive rheumatic outpatien...

Pennsylvania State University, University Park, PA 16802 Various attempts have been made (o develop models for predicting the development of damage in metals and alloys due to pitting corrosion. These muOcIs may be divided into two cliu.ses: the cmpirieiil approach which employ.s extreme value statistics, and the deterministic approach based on perceived mechanisms for nuclcation and growth of ...

The influence of the addition of copper on the resistance to pitting corrosion of stainless steels has been investigated using different experimental techniques––current transient analysis, polarization curves in acidic media, pitting and repassivation potential measurements, XPS and SEM observations––so that pit initiation, propagation and repassivation could be analysed separately. Copper add...

The inhibition mechanism of sodium oleate (C17H33COONa) for pitting corrosion of aluminum alloy (AA) 2024 in 0.1 mol L NaCl solution was investigated using potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), scanning electron microscopy with energy dispersive spectrometer (SEM-EDS) and X-ray photoelectron spectroscopy (XPS). C17H33COONa showed good inhibition effect on u...

DESCRIPTION Patient is a 65-year-old right-hand-dominant man. He presents with a 15-year history of progressive left small finger contracture with occasional palmar pain. On examination, he has a palpable palmar cord. Contraction of left small finger metacarpophalangeal (MP) joint was noted to be 60 • .

background: the present study was designed to ascertain serial changes on distal radius radiographic parameters attributable to aging.       methods: in this prospective study, the sample consisted of 120 healthy individuals who were divided into four age groups each containing 15 males and 15 females. in the two below-20-year-old groups, only ulnar variance could be investigated. wrist radiogr...

INTRODUCTION The superficial and deep palmar arterial arches are the main sources of blood supply to all structures in the human hand, and variations in these arterial arches are quite common. Although several studies have reported diameters and variations of these arches, to the authors' knowledge, no study has correlated such changes to handedness in adults. It is likely that dominance may pl...

Background Patients with Kirner's deformity often seek medical attention for aesthetic improvement when they reach the age of approximately 10 years, when the deformity becomes evident. The operative technique described in textbooks is the palmar opening-wedge with multiple osteotomies through a mid-lateral incision, which is technically demanding. The purpose of this article was to introduce o...

BACKGROUND The present paper aims to study the prevalence of the various manifestations of hyperhidrosis in patients who sought treatment in a specialized ambulatory in the state of São Paulo. OBJECTIVES Opposite to previous studies, this paper studies the different combinations of sweating sites, not being restricted to the main complaint site of the patients, but taking into consideration s...
