[Goodpasture's syndrome. Observations on a case].

Following a review of the most recent aetiopathogenetic theories and therapeutic records of Goodpasture's syndrome, a personal case is reported. Stress is laid on the extreme clinical variability of the disease and on the role which disseminated intravascular clotting can have on its course.

[Renal tubular acidosis during a course of liver cirrhosis].

In a group of 23 patients suffering from liver cirrhosis, metabolic acidosis was always observed, in most cases corrected by respiratory alkalosis. In 8,6% of cases a tubular renal acidosis (type I), in 8,6% (type II) and 8,6% a loss of urinary bicarbonate without acidosis were observed.

[Hepatorenal syndrome].

The term "hepatorenal syndrome" is used to bring together a variety of syndromes whose common feature is liver and kidney parenchymal distress. For this reason, its use has been questioned by many workers. A subdivision into acute and chronic forms is proposed and emphasis is placed on the common physiopathogenetic processes, together with the notable importance of DIC. This approach is supported by reference to a series of 36 chronic and 6 acute cases.

Effects of stimulated hip extension moment and position on upper-limb support forces during FNS-induced standing--a technical note.

This study explores the effects of active hip extension moment produced by electrical stimulation on the support forces the arms must exert through an assistive device during quiet erect standing with functional neuromuscular stimulation (FNS) in individuals with spinal cord injuries (SCI). A static sagittal plane biomechanical model of human standing was developed to predict the effects of stimulated hip extension moment and sagittal plane hip angle on the arm support necessary to maintain an upright posture. Two individuals with complete thoracic SCI were then tested while they stood with continuous stimulation to the knee and trunk extensors. The steady-state active extension moment exerted at the hip was varied by activating different combinations of hip extensor muscles with continuous stimulation while steady-state support forces applied to the arms and feet during standing were measured. The steady-state support forces imposed on the arms during quiet standing decrease with increased stimulated hip extension moment and are highly dependent upon hip flexion angle, as predicted by the biomechanical simulations. Experimentally, the combination of gluteus maximus and semimembranosus stimulation produced three times more steady-state hip extension moment than did stimulation of the gluteus maximus and adductor magnus. This resulted in a ten-fold decrease in body weight supported on the arms. More vertical postures (smaller hip flexion angles) improve the effectiveness of the hip extensor muscles in reducing the support forces placed on the arms. A single Newton-meter of stimulated hip extension moment with the hips fixed at 5 degrees of flexion results in almost five times the reduction in arm support forces as with the hips at 20 degrees. To minimize the forces applied by the arms on an assistive device for support while standing with FNS, these preliminary results suggest that (1) efforts should be made to assume the most erect postures possible and (2) muscles and stimulation paradigms that maximize active hip extension moment should be chosen.
