The association between anomalous X-ray findings of the respiratory organs and their clinical manifestation

Abstract

A retrospective study of hospital charts was conducted for the purpose of analysing the association of roent-genphotographs obtained routinely at the Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto, Brazil, since 1967, with the records of respiratory symptoms and pneumopathic diagnosis found in the medical case histories as from the patients' first clinical out-patient consultation at that hospital. For this purpose, 997 patients with abnormal pulmonary roentgenphotography findings were matched according to sex and age with the same number of controls (normal roentgenphotography). It was observed that in one third of the medical histories there was no record of any anamnesis of the respiratory system. A greater proportion of respiratory symptoms and pneumopathic diagnoses was registered in the case group. The same finding separated the patients into two groups according to the severity of the lesions. Hemoptysis and thoracic pain were the symptoms that better differentiated sick from normal patients. A selective utilization of roentgenphotography is recommended, with the method being applied only to patients presenting hemoptysis, thoracic pain and cough/expectoration, either alone or in combination.
