Objective:
To evaluate the intra- and inter-reliability and the ease of measuring the quadriceps muscle thickness using bedside ultrasound.
Methods:
This is a prospective, observational study. The assessment of quadriceps muscle thickness was performed at two reference points and was quantified using portable B-mode ultrasound in two healthy volunteers. For standardization of measurements and validation of image collections, the team was trained through theoretical and practical classes, with a 6-hour workload.
Results:
A total of 112 images were examined by the coach and compared with the trainees. Pearson’s correlation analysis found an excellent relationship between the coach and all trainees (R2 > 0.90). The best association was between the coach and the dietitians (R2: 0.99; p < 0.001), and the worst association was between the coach and the medical trainees (R2: 0.92; p < 0.001). In the Bland-Altman comparison, the highest error rate found between coach and trainees was 5.12% (95% confidence interval [CI] 3.64-12.37), and the lowest was 1.01% (95%CI 0.72 - 2.58); the highest bias of the values described was -0.12 ± 0.19, and the lowest was -0.01 ± 0.04.
Conclusion:
The data analyzed showed a good correlation between the measurements made by the coach and trainees, indicating that ultrasound of the quadriceps muscle is a viable and easily applicable tool.

Views0See moreBACKGROUND AND OBJECTIVES: Myocardial contusion is often associated with blunt chest trauma. Its diagnosis is challenging to the professionals who work in emergency department due to nonspecific symptoms and the lack of auxiliary exams with enough accuracy to diagnose. Among the available diagnostic tools, the biomarkers of myocardial injury troponin I and troponin T have stood out. Troponins are proteins of the citocellular apparatus, released into the bloodstream only after the disruption of myocytes cellular membrane. Therefore they are highly specific to detect myocardial injuries. CONTENTS: We performed a clinical review using the electronic databases MedLine and LILACS from January 1980 to November 2006 about the importance of a serial measurement of troponin I and T as a diagnostic tool as well as predictor of unfavorable clinical outcome in patients with myocardial contusion after a blunt chest trauma. CONCLUSIONS: Although troponins I and T are more specific than usual biomarkers CKMB and CK, these two first biomarkers show a low sensitivity and positive predictive value to diagnosis myocardial contusion. Patients with ECG abnormalities, troponins elevations or both should remain in an intensive care unit (ICU) for at least 24 hours, period in which they cam develop most of the complications related to myocardial contusion.
