Test-retest reliability and validity of body composition methods in adults.

Cost-effective and efficient body composition measurement devices that are reliable and valid are necessary for identifying health risk as well as for understanding the effectiveness of lifestyle interventions. The objective of this study was to evaluate the test-retest reliability and validity of three body composition measurement devices. Forty-nine adults (mean age (SD) = 31.

A comparison between the National Food Survey and the Family Expenditure Survey food expenditure data.

Objective: Household budget surveys (HBSs) have been used to assess nutritional information for epidemiological purposes. The agreement between this information and other comparable data needs to be examined. The aim of this project was to compare household food expenditure data between two British HBSs: the National Food Survey (NFS) and the Family Expenditure Survey (FES).

Methodology for rendering household budget and individual nutrition surveys comparable, at the level of the dietary information collected.

Objective: To describe the methodology applied in order to render comparable, at the level of the dietary information collected, the household budget survey (HBS) and individual nutrition survey (INS) data from four European countries (Belgium, Greece, Norway and the United Kingdom).

Setting: In Belgium, data from the HBS of 1987-88 were compared with data from the Belgian Interuniversity Research on Nutrition and Health collected from 1980 to 1985. In Greece, data from the HBS undertaken in 1993-94 in the greater Athens area were compared with data collected around 1994 in the same region, in the context of the Greek segment of the European Prospective Investigation on Cancer and Nutrition study.

[Pedicle torsion, hemorrhagic ovarian infarct. A rare cause of pediatric acute abdomen].

The most common cause of acute abdomen in a child is acute appendicitis followed by mesenteric lymphadenitis, invagination, strangulation-ileus as a result of volvulus and more rarely perforated Meckel's diverticulum. However even with a child, from a differential diagnosis' aspect, a gynaecological cause should be taken in account too. From time to time one comes across a polycystic-alterated, with twisted lig.

Intraoperative sonographic measurements of the internal mammary artery as a coronary bypass conduit.

Intraoperative visualization of coronary artery anatomy and morphology is an innovative method to evaluate patients undergoing coronary bypass surgery. With the high frequency ultrasonic technique we were able to measure diameters of internal mammary arteries (IMA) before and after dilatation. Probe dilatation of the IMA led to an increase of the IMA diameter of 46% while balloon dilatation was more successful resulting in an enlargement of 66%.

Cardiac myxoma. Clinical and pathologic features in 15 cases.

Neoplasms are rare cardiac findings of which myxomas comprise about 75%. We report of 15 patients, predominantly female (60%) with a mean age of 58.8 years.

[Myxoma of the heart: symptoms masked by an atrial septal defect].

A 68-year-old woman, known to have a secundum atrial septal defect which had been asymptomatic, reported dyspnea and occasional chest pain for two years. Admission examination revealed orthopnea, cyanosis, polycythemia and inflow congestion of the upper part of the body. After some blood-letting, nifedipine and nitrates brought immediate relief of symptoms.

Relationship between erythrocyte 2,3-diphosphoglycerate and age in a normal population.

The concentration of 2,3-diphosphoglycerate in erythrocytes was determined in 369 male and 376 female normal subjects, 1 to 86 years of age, derived from the Greek population. It was inversely correlated (P less than 0.01) with age.
