The images were read by a radiologist before endoscopy then reviewed later by a senior radiologist blinded to the endoscopy findings. Endoscopy was performed routinely.

Results: Foreign bodies were found by endoscopy in 70 of the 303 children. The initial multidetector computed tomography reading was 94% sensitive and 95% specific. For the review, the images for

91 patients were excluded because of motion blurring or absence of larynx visualisation; in the remaining 212 patients, sensitivity was 98% and specificity 97%.

Conclusion: Multidetector computed tomography as performed in our patients cannot replace endoscopy, which remains the reference standard. Nevertheless, multidetector. computed tomography is sufficiently sensitive to be of value when foreign body aspiration is not considered initially or when endoscopy is likely to prove challenging.

“The aim of this study was the comparison of in vitro dissolution and in vivo bioavailability

of two different brands of diclofenac sodium (CAS 15307-86-5) selleck screening library enteric coated tablets in healthy male Iranian volunteers in a single-dose, randomized, open-label, single blind study, which was conducted according to a crossover design in healthy volunteers. A washout interval of two weeks was selected between administrations to each subject in this study. Serial venous blood samples over 10 h after each administration to measure diclofenac sodium concentration in serum were obtained, and placed into tubes containing sodium heparin. Then

the plasma was separated and kept frozen at -20 degrees C for subsequent analysis with a modified HPLC method with UV detection. In addition, the in vitro dissolution study was performed on the brands. For the test and reference formulation, mean C(max) values were 2257.3 (ng/ml) and 2156 (ng/ml), respectively. The mean AUC(0)(t) and ADC(0)(infinity) were 5726.1 (ng . h/ml) and 5917.8 (ng . h/ml) for the test and 5689.9 (ng . h/ml) and 5967.4 (ng . h/ml) for the reference formulation, respectively. Results show that the 90% confidence intervals for the ratio of test and reference products in C(max) (101.4-114.9%), AUC(0)(t) (96.3-109.1%) selleck compound and AUC(0)(infinity) (94.7-107.3%) were all within the 80-125% interval proposed by the FDA and EMA. Both formulations released > 80% of drug within 30 min in buffer pH = 6.8 medium. Therefore the diclofenac soditun enteric coated tablets of the test and reference formulations are bioequivalent in terms of rate and extent of absorption.”
