Background and aim: Psoriasis is a chronic inflammatory dermatosis that affects 0.6% to 4.8% of the population. Phototherapy is commonly used in the treatment of this disease. According to the results of previous studies that showed difference in minimal erythema dose between different body sites, it seems that the responses of psoriatic lesions are also different in various body sites. O...

syncope5 and suppuration in the groin after extra-vascular injection.6 The great danger, however, is that it is radioactive : ill results from this have been reported.9 Sodium iodide is likely to produce severe reactions and much pain, but it is still used for the aorta.10, 11 Organic iodides are the substances now usually employed. The most favoured is diodone (diodrast, Pyelosil). It is prepa...

In patients with COPD, the degree of functional impairment appears to differ between the upper and lower limbs. Significant dyspnea and fatigue have been reported by these patients when performing tasks with unsupported upper limbs and two mechanisms have been proposed to explain this fact: neuromechanical dysfunction of respiratory muscles; and changes in lung volume during such activities. Th...

Arterial embolisms in the lower limbs occur frequently, and are of great interest to the vascular surgeon. The authors studied 159 cases of arterial embolisms in lower limbs from January 1991 to July 1993. Ages varied from 12 to 98, with a mean of 58. Eighty patients were male and 78 were female. In most cases, etiology of the embolus was well-established, and mainly caused (78 percent) by atri...

This project represents a continuous effort of Mauch Laboratories toward the improvement of artificial limbs, particularly for the lower limbs. Work on five items has been underway : A semivoluntary Swing and Stance Control knee mechanism (S-N-S System), an automatically controlled Tri-axial Ankle mechanism, a fully Voluntarily Actuated Swing and Stance Control knee mechanism, a mechanical low-...
