Bronchodilator responsiveness: interpret with caution.
Bronchodilator responsiveness (BDR) is widely considered to be a key diagnostic criterion for asthma, and is used to differentiate asthma from chronic obstructive pulmonary disease (COPD). Currently, the threshold of a 12% increase in FEV1 from baseline following inhaled salbutamol, with at least a 200 ml increase in absolute terms, is recommended as a response indicative of asthma, although re...
متن کاملPresenilin 1 Glu318Gly polymorphism: interpret with caution.
BACKGROUND The significance of the presenilin 1 (PSEN1) Glu318Gly polymorphism has been described as either a causal mutation with reduced penetrance or a benign polymorphism. When this polymorphism is found in a symptomatic person with a family history of dementia, counseling on recurrence risk becomes very problematic. OBJECTIVE To demonstrate that the PSEN1 Glu318Gly polymorphism should be...
متن کاملHigh Serum Procalcitonin: Interpret with Caution
Serum procalcitonin (PCT), which is usually produced in thyroid Ccells, is a precursor of calcitonin. In general, PCT is not released into the blood and, therefore, cannot be detected in healthy individuals [1]. However, serum procalcitonin increased significantly in response to stimulation by bacterial infections showing a favorable pharmacokinetic profile as clinical markers for bacterial inf...
