[Multiple recurrences of cardiac myxomas with acute tumoral pulmonary embolism]. / Múltipla recorrência de Mixomas Cardíacos com embolia pulmonar aguda.

We report the case of a 42-year-old female with a second recurrence of cardiac myxoma. Her first diagnosis was at the age of 24 years, when cardiac tumors were withdrawn from her right ventricle and left atrium. Her first recurrence was at the age of 36 years, when tumors were removed from the left and right atria, and the right ventricle. Six years later, the patient was admitted to the Hospital das Clínicas de Porto Alegre complaining of sudden dyspnea, dry cough, and pain in the right hypochondrium, which bore no relation to breathing. The transesophageal echocardiography showed a small tumor in the interatrial septum, close to the superior vena cava, and 2 larger tumors in the right ventricle, 1 close to the outflow tract and the other almost completely obstructing the right branch of the pulmonary artery. The patient was referred to surgery, in which myxomas were removed from the right atrium and ventricle with extension to the right pulmonary artery. The postoperative period was uneventful.

[Levels of essential elements in pubic hair of women with threatened abortion and in full-term pregnancy]. / Metale esencjalne we wlosach lonowych u kobiet z poronieniem zagrazajacym i w ciazy donoszonej.

Concentrations of iron, zinc and copper were determined in public hair of women with threatened abortion and in full-term pregnancy. The aim of the studies was to find differences between the levels of studied elements in public hair of women with threatened abortion and in full-term pregnancy and to test whether parity, place of residence and smoking influence the measured levels. A study population consisted of 101 women aged 18-41 years. Atomic absorption spectrophotometry was the method employed to determine the concentrations of the studied elements. The levels of copper were elevated in smokers in full-term pregnancy in comparison to nonsmokers.

[Levels of cadmium in pubic hair of women with threatened abortion and in full-term pregnancy]. / Stezenia kadmu we wlosach lonowych u kobiet z poronieniem zagrazajacym i w ciazy donoszonej.

Concentrations of cadmium were determined in pubic hair of women with threatened abortion and in full-term pregnancy. The aim of the studies was to find differences between the levels of cadmium in pubic hair of women with threatened abortion and in full-term pregnancy and to test whether parity, place of residence and smoking influence the measured levels. A study population consisted of 101 women aged 18-41 years. Atomic absorption spectrophotometry was the method employed to determine the concentrations of cadmium. The concentrations of cadmium in pubic hair were elevated in women living in town and were statistically significant higher in smokers in comparison to nonsmokers.

[Levels of lead in pubic hair of women with threatened abortion and in full-term pregnancy]. / Poziomy olowiu we wlosach lonowych u kobiet z poronieniem zagrazajacym i w ciazy donoszonej.

Concentrations of lead were determined in pubic hair of women with threatened abortion and in full-term pregnancy. The aim of the studies was to find differences between the levels of lead in pubic hair of women with threatened abortion and in full-term pregnancy and to test whether parity, place of residence and smoking influence the measured levels. A study population consisted of 101 women aged 18-41 years. Atomic absorption spectrophotometry was the method employed to determine the concentrations of lead. The lead levels were significantly higher in pubic hair of women with threatened abortion; as compared to the healthy gravidas at term and nonpregnant controls the hair levels of lead were elevated in smokers in comparison to nonsmokers.

[Recurrence of multicavitating cardiac myxoma]. / Recorrência de mixoma cardíaco multicavitário.

A 24 years-old female patient with congestive heart failure and clinical, electrocardiographic and radiologic findings compatible with pulmonary stenosis. Angiocardiography study diagnosed a tumor of the right ventricule (RV). Large tumor of the RV and smaller tumors of the left atrium were removed by surgical treatment. Six years later, a 2 cm tumor was identified in the RV. The tumor's growth was accompanied by bidimensional transthoracic echocardiograms. After 6 years a transesophageal echocardiogram showed three tumors, one in the RV and one in each of the right and left atria. These tumors were successful removed by new surgical treatment.
