The accurate diagnosis of chest pain is often difficult. We review the differential diagnosis of chest pain and the diagnostic studies used in the evaluation of chest pain syndromes. Myocardial ischemia, aortic dissection, pulmonary embolism, pericarditis, and gastroenterologic sources of chest pain are the most common. The chest X-ray, electrocardiogram, echocardiogram, heart catheterization studies, and esophageal studies are helpful diagnostically.

Comparative StudyComparison of creatinine and inulin clearances in multiple trauma.
Creatinine clearance (Ccr) is a good predictor of renal dysfunction. However, numerous analytical interferences have been observed with the classical measurement of creatinine by Jaffé's procedure. This prospective study was conducted to compare 4 methods for determining creatinine; and also endogenous creatinine clearance with inulin clearance (Cin) to estimate the glomerular filtration rate. ⋯ The best correlations between inulin clearance and creatinine clearance were observed for Jaffé's rapid kinetics (r = 0.90) in the control group and for the enzymatic procedure in the multiple trauma group (r = 0.55). Plasma creatinine is not a useful indicator in multiple trauma. The correlation between creatinine clearance and inulin clearance is not very strong in multiple trauma, indicating that the relative evolution (not the absolute values) of creatinine clearance is of interest.
