[Сardiac myxoma: challenge in diagnostics. Case report].

Cardiac myxoma is the most common primary benign cardiac tumor (up to 50% of all primary cardiac neoplasms). The implementation of the modern imaging techniques into the clinical practice, particularly, 2D echocardiography, computed tomography and magnetic resonance tomography (MRI) results to the prompt diagnosis of the myxoma. However, the absence of specific clinical features, insufficient awareness of this condition among the physicians along with a rare prevalence, may lead to a misdiagnosis. This case report is notable for the relatively late diagnosis of a giant left atrial myxoma due to a number of circumstances but with successful surgical treatment.

[The clinico-laboratory dynamics in the reaferon treatment of glomerulonephritis patients with the nephrotic syndrome]. / Kliniko-laboratornaia dinamika pri lechenii reaferonom bol'nykh glomerulonefritom s nefroticheskim sindromom.

Overall 40 chronic glomerulonephritis patients with nephrotic syndrome were treated by reaferon. All the patients underwent clinical and laboratory examinations and nephric biopsy. As a result of the treatment, all the patients demonstrated an increase of the level of glomerular filtration, stabilization of protein and lipid metabolism along with the lowering of diurnal proteinuria. Reaferon exerted a beneficial effect on cellular factors of immunity. In some cases, the use of reaferon can be a definite alternative of the conventional treatment methods.

[Anti-infectious immunity and bacteriuria in patients with the nephrotic syndrome]. / Protivoinfektsionnyi immunitet i bakteriuriia u bol'nykh s nefroticheskim sindromom.

The study was made of antiviral antibodies to respiratory viruses, mycoplasma, O-streptolysin, of qualitative and quantitative characteristics of bacteriuria in 52 patients with nephrotic syndrome (NS) due to glomerulonephritis against 18 NS control subjects without glomerulonephritis. Significant differences between the groups appeared in the titers of antibodies to Coxsackie and influenza A viruses. O-streptolysin. Persistence of viral latent infection in NS is suggested as well as a trigger role of viruses in the disease onset and that of other urinary inflammatory affections whose incidence is now on the increase.

[Serodiagnosis of patients with glomerulonephritis]. / Serodiagnostika bol'nykh glomerulonefritom.

A comprehensive clinical and morphologic examination of 160 nephrologic inpatients included titration of antibodies to respiratory viruses and to HBsAg and of streptolysin O. A correlation was detected between immunity status parameters and the presence and severity of proteinuria in the patients with chronic glomerulonephritis. Besides routine clinical and laboratory examinations, thorough serologic and virologic studies are necessary for this patient population, for such studies will help determine the trigger mechanism of the disease and thus predict the possible development of the condition.
