We studied standing anteroposterior roentgenograms from 140 scoliosis patients and obtained a correction equation for body height by Cobb angle. This equation is applicable to patients with a double curve or special curve pattern as well as patients with a single curve. The repeatability of the method examined with this equation was higher than that with the previous correction method for body ...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2016216542 DESCRIPTION A 67-year-old never-smoking man with a wellknown congenital diaphragmatic hernia, verified on a 3-year-old chest X-ray (figure 1), consulted his general practitioner due to the detection of intermittent blood stool for 2 months, but emphasised...

BACKGROUND Pulmonary involvement in adult patients with inflammatory bowel disease (IBD) seems more common than previously appreciated. Its prevalence and development over time in pediatric IBD patients are largely unknown. OBJECTIVES The aim was to study lung function including fraction of exhaled nitric oxide (FeNO) and transfer capacity for carbon monoxide (TLCO) in pediatric IBD patients ...

Workers involved in hydraulic fracking processes are exposed to various types of chemicals and dusts in their workplaces, such as proppants, which hold open the fissures created in the fracking process. Recently, ceramic proppants have been developed that may be less hazardous to workers than traditional proppants. Pulmonary function testing of workers producing ceramic proppant was used to ass...

Prediction equations for estimating lung volumes have been determined for Caucasians, African-Americans, and Mexican-Americans. These separate equations were determined because of differences in thoracic morphology between people of various racial groups, making it impossible to use one prediction formula to accurately estimate lung volumes for all individuals. One hundred ninety-one adolescent...
