[Cardiac echinococcosis. Report of a case].

Cardiac hydatid disease represents 0.02-2% of the possible locations of the parasite. The case of an asymptomatic 60-year-old male patient, hospitalised for mnesic and cognitive disease, and with history of hepatic and pulmonary echinococcosis is reported.

[Diagnosis of nonobstructive hypertrophic cardiomyopathy in a patient with Down's syndrome].

This report describes the case of a patient with nonobstructed hypertrophic cardiomyopathy and Down's syndrome (47,XY, +21) in a 31 year old patient. Diagnosis of hypertrophic cardiomyopathy was made subsequently to ECG and two dimensional echocardiography findings. Personal and familial anamnesis and physical examination were negative.

[Mental stress and ambulatory monitoring of arterial pressure].

The aim of this study was to validate the use of arithmetical mental stress testing as an indicator of an abnormal subject's response to stress in general. For this purpose 82 males (mean age 31 +/- 7 years, mean body surface area--BSA--1.76 m2), free from cardiovascular disease, underwent mental stress testing.

[Cardiovascular aspects of Martin-Bell syndrome].

Cardiovascular anomalies have been studied in 13 subjects (8 males and 5 females, average age 15 +/- 7 years) affected from fragile X syndrome. This group has been examined by standard-ECG, Holter-ECG, echocardiography (M-mode, B-mode, Doppler and color-Doppler). The results have been compared with a control group of 39 subjects (20 males and 19 females, average age 15 +/- 5 years), with non genetic mental retardation.

[Prevalence of pulmonary valve insufficiency in healthy children: a Doppler color study].

One hundred patients, institutionalized for mental retardation, aged between 3 and 14 years (mean age 12.2 +/- 3) and free from cardiovascular and pulmonary diseases, were studied using Doppler technique (pulsed wave-continuous wave and color-coded Doppler), to evaluate the prevalence of pulmonary regurgitation. The authors, utilizing a triple method (diastolic turbulence above pulmonary valve detected by pulsed wave Doppler or diastolic flow detected by continuous wave Doppler, presence of regurgitant pulmonary color-jet, from short axis view, toward the right ventricular outflow tract, and presence of the same feature in the color m-multigate) to detect the presence or absence of pulmonary regurgitation found 73% positivity.
