Study of the cardiac alterations in HIV-infected children consequent to the antiretroviral therapy. Prospective study of 47 cases.

Objective: Detect of cardiac alterations in children with AIDS and compare their evolution with the administration of only one anti-retroviral and the recent cases who received drugs in combination.

Methods: We prospectively studied 47 children in 3 groups: group 1, 20 cases treated only with zidovudine; group 2, 10 patients treated initially with zidovudine and later with a combination of drugs and in group 3, 17 patients, who receiced two or three since the beginning. In all patients it was done chest X-ray, EKG and echocardiography every 6 months and after death complete pathological study.

Cardiac abnormalities in the acquired immunodeficiency syndrome. A prospective study with a clinical-pathological correlation in twenty-one adult patients.

OBJECTIVE - To evaluate the cardiac abnormalities and their evolution during the course of the acquired immunodeficiency syndrome, as well as to correlate clinical and pathological data. METHODS - Twenty-one patients, admitted to the hospital with the diagnosis of acquired immunodeficiency syndrome, were prospectively studied and followed until their death. Age ranged from 19 to 42 years (17 males).

Rheumatic carditis treated with high doses of pulsetherapy methylprednisolone. Results in 70 children over 12 years.

Purpose: To report the result of patients treated with IV methylprednisolone divided into three groups and compare their follow-up during the last 12 years.

Methods: Seventy children with active rheumatic carditis (76 episodes) in heart failure Class III and IV (NYHA) were studied. The diagnosis was based on modified Jones' criteria.

Antigen retrieval on epoxy sections based on tissue infiltration with a moderately increased amount of accelerator to detect immune complex deposits in glomerular tissue.

We wanted to examine the effect of antigen retrieval on epoxy sections where the tissue had been infiltrated by resin containing moderately increased amounts of accelerator. The concentration of accelerator DMP-30 (Tri(Dimethyl Amino Methyl) Phenol) was varied in the range of 0% to 4% in the infiltration step of the tissue processing. Some of the epoxy sections were fixed in osmium tetroxide, and for others this fixative was avoided.
