Prediction equations for spirometry in four- to six-year-old children.

Objective: To generate prediction equations for spirometry in 4- to 6-year-old children.

Methods: Forced vital capacity, forced expiratory volume in 0.5s, forced expiratory volume in one second, peak expiratory flow, and forced expiratory flow at 25-75% of the forced vital capacity were assessed in 195 healthy children residing in the town of Sete Lagoas, state of Minas Gerais, Southeastern Brazil.

[Pulmonary function of children with acute leukemia in maintenance phase of chemotherapy].

Objective:: The aim of this study was to assess the pulmonary function of children with acute leukemia.

Methods:: Cross-sectional observational analytical study that enrolled 34 children divided into groups A (17 with acute leukemia in the maintenance phase of chemotherapy) and B (17 healthy children). The groups were matched for sex, age and height.

[Effects of breathing exercises on breathing pattern and thoracoabdominal motion after gastroplasty].

Objective: To evaluate breathing pattern and thoracoabdominal motion during breathing exercises.

Methods: Twenty-four patients with class II or III obesity (18 women; 6 men) were studied on the second postoperative day after gastroplasty. The mean age was 37 +/- 11 years, and the mean BMI was 44 +/- 3 kg/m(2).
