Percutaneous management of benign renal cysts

Percutaneous emptying of benign renal cysts represents the adopted treatment for this kind of pathology. The introduction of pure ethilic alcohol (95 degrees) is usually associated with emptying because it determines the necrosis of the secreting epithelious with recurrences and little significant complications. This treatment is the less bloody solution that can be executed in surgery and for this reason it is proposed in the time as an alternative to surgery treatment of removal.

Coronary artery dissection - a complication of cardiac catheterization without sequelae: case report and review of the literature

This report describes an acute right coronary artery dissection occurring during diagnostic cardiac catheterization. Following catheter manipulation in the vicinity of the aortic valve, the patient complained of mild chest discomfort and had transient electrocardiographic evidence of acute inferior wall myocardial infarction with runs of 2:1 atrioventricular block. Within 5 min, the EKG reverted to precatheterization appearance, and the patient was asymptomatic. Coronary angiography revealed a dissection of the proximal vessel without obstruction. The patient had no clinical sequelae while monitored in the intensive care unit. The patient underwent elective aortic and mitral valve replacement. The area of the dissection was directly visualized, and no abnormality was noted. We review the literature of spontaneous and iatrogenic coronary artery dissections with regard to pathology, diagnosis, and prognosis, and make recommendations for therapy.     

Making electrofused magnesia-alumina spinel for producing high-grade refractories

Conclusions The basic technical parameters for melting and producing magnesia-alumina spinel in an electric arc furnace OKB-514 were evaluated and specified. A study was made of the properties of certain compositions of spinel, the melting of an experimental batch of spinel, and using this as a basis, high-qualityroof products were made.Translated from Ogneupory, No. 4, pp. 41–45, April, 1972.
