Multicenter Study[Student patient relationship from the patient's point of view].
Patients are becoming increasingly active in their relationship with medical professionals. Their relationship with medical students needing to learn clinical skills, may be specially problematic if patients are not willing to accept their involvement in the medical team. ⋯ Patients in Chilean public and private hospitals were in general positive regarding student's participation in their care. Students' clinical practice ought to strictly respect patients's rights, and patients should be considered volunteers who generously agree to cooperate with the education of medical students.

[Brain and spinal cord magnetic resonance imaging in spastic paraparesis associated to human T-lymphotropic virus].
The spastic paraparesis associated to HTLV-1 causes degenerative pyramidal tract lesions of the spinal cord and affects cortical-nuclear connections in the brain. ⋯ Most patients with tropical spastic paraparesis have alterations in brain or spinal cord magnetic resonance imaging. The magnetic resonance lesions are concordant with functional impairment. The characteristics of the imaging in TSP/HAM patients can be helpful in the differential diagnosis of patients with paraparesis.

Patients with type B dissections are treated with surgery if they have complications like rupture, growth or visceral ischemia. ⋯ He was treated successfully with the placement of an endoluminal graft. He was discharged five days after the procedure in good conditions. After one year of follow up, the patient remains asymptomatic.

[Short-term Lycopersicum esculentum consumption may increase plasma high density lipoproteins and decrease oxidative stress].
Tomato has a high antioxidant capacity due to its high content of vitamin C, vitamin E and lycopene that is a powerful free radical scavenger. However, the effects of tomato on plasma lipoproteins is not well known, and there is little evidence about the relationship between tomato consumption and oxidative state changes in humans. ⋯ Dietary supplementation of concentrated tomato juice significantly increases lycopene levels and HDL cholesterol. Non significant changes observed in TRAP, catalase and superoxide dismutase were observed during the supplementation period.

Randomized Controlled Trial[Controlled trial of dexamethasone compared with droperidol and ondansetron for the treatment of postoperative nausea and vomiting].
Dexamethasone is useful as prophylaxis for postoperative nausea and vomiting (PONV). ⋯ Short term efficacy of dexamethasone to treat PONV was similar to ondansetron, but inferior to droperidol. Further studies are needed to define the duration of this effect of dexamethasone.
