Could lower bone turnover be a cause of chest pain during childhood?

Chest pain, a frequent complaint during childhood, rarely originates from a cardiac pathology. Although it usually is idiopathic, it also could be associated with psychogenic, musculoskeletal, respiratory, and digestive disorders. This study aimed to investigate a possible relation between bone mineral density and chest pain in children.

The role of viral agents in aetiopathogenesis of acute rheumatic fever.

The reason why abnormal immune response exists in acute rheumatic fever is not exactly explained. The influence of co-pathogens like certain viruses were mentioned regarding the initiation of the immunological reaction in acute rheumatic fever patients by several authors since 1970. This study was designed to find the role or effect of some viral infections in the development of rheumatic fever.

Cardiac abnormalities in children with systemic lupus erythematosus.

Children and adolescents with systemic lupus erythematosus (SLE, n = 14) with no cardiac symptoms were examined for cardiac involvement by physical examination, electrocardiography (ECG) and echocardiography. The indexes of left ventricular (LV) systolic and diastolic function were compared with the findings of 20 healthy, age-matched control subjects. Echocardiographic examination revealed mild tricuspid valve regurgitation in three, and moderate tricuspid and mitral valve regurgitation in two patients.
