BACKGROUND: This retrospective comparative study aims to evaluate the surgical outcomes and complications of two surgical methods for simple fractures of the humeral shaft; minimally invasive anterior plating and open reduction combined with internal fixation. METHODS: A total of 26 patients with humeral shaft simple fractures, who had surgery between June 2009 and September 2013 and were followed-up at least 12 months, were included in our analysis. They were divided into two groups; group 1 comprised of 12 patients who underwent minimally invasive anterior plating and group 2 comprised of 14 patients who underwent an open reduction and internal fixation. The clinical outcomes, radiological results, and complications were compared and analyzed. RESULTS: We found that bone union was achieved in all patients, and the mean union periods were 20.7 +/- 3.34 and 20.3 +/- 3.91 weeks for groups 1 and 2, respectively. In most patients, we found that shoulder and elbow functions were recovered. At 12 months post-operation, we found that the Korean Shoulder Scoring system, the University of California at Los Angeles score and Mayo elbow performance score were 91.4 +/- 7.97, 33.4 +/- 1.15, and 90.8 +/- 2.23 for group 1, and 95.2 +/- 1.53, 33.3 +/- 1.43, and 90.17 +/- 1.85 for group 2. In terms of complications, we found that 2 patients had radial nerve palsy after open reduction and internal fixation, but all cases spontaneously resolved within 6 months. Complications such as infection and loss of fixation were not reported. CONCLUSIONS: Both minimally invasive anterior plating and open reduction with internal fixation produced satisfactory outcomes in the treatment of simple fractures of the humeral shaft.

BACKGROUND/AIMS: Despite the clinical importance and widespread use of pulse wave velocity (PWV), there are no standards for pulse sensors or for system requirements to ensure accurate pulse wave measurement. We assessed the reproducibility of PWV values using a newly developed PWV measurement system. METHODS: The system used in this study was the PP-1000, which simultaneously provides regional PWV values from arteries at four different sites (carotid, femoral, radial, and dorsalis pedis). Seventeen healthy male subjects without any cardiovascular disease participated in this study. Two observers performed two consecutive measurements in the same subject in random order. To evaluate the reproducibility of the system, two sets of analyses (within-observer and between-observer) were performed. RESULTS: The means+/-SD of PWV for the aorta, arm, and leg were 7.0+/-1.48, 8.43+/-1.14, and 8.09+/-0.98 m/s as measured by observer A and 6.76+/-1.00, 7.97+/-0.80, and 7.97+/-0.72 m/s by observer B, respectively. Betweenobserver differences for the aorta, arm, and leg were 0.14+/-0.62, 0.18+/-0.84, and 0.07+/-0.86 m/s, respectively, and the correlation coefficients were high, especially for aortic PWV (r=0.93). All the measurements showed significant correlation coefficients, ranging from 0.94 to 0.99. CONCLUSIONS: The PWV measurement system used in this study provides accurate analysis results with high reproducibility. It is necessary to provide an accurate algorithm for the detection of additional features such as flow wave, reflection wave, and dicrotic notch from a pulse waveform.

The J-curve effect describes an inverse relation between low blood pressure (BP) and cardiovascular complications. This effect is more pronounced in patients with preexisting coronary artery disease (CAD), hypertension or left ventricular hypertrophy (LVH). The recent large clinical outcomes trials have observed a J-curve effect between a diastolic BP of 70-80 mmHg as well as a systolic BP <130 mmHg. The J-curve phenomenon does not appear in stroke or renal disease. This is because the coronary arteries are perfused during diastole, but the cerebral and renal perfusion mainly occurs in systole. Therefore, caution should be taken to maintain the diastolic blood pressure (DBP) at minimum of 70 mmHg and possibly to maintain the DBP between 80-85 mmHg in patients with severe LVH, CAD or vascular diseases. BP control in high-risk elderly patients should be carefully done as undergoing aggressive therapy to lower the systolic blood pressure below 140 mmHg can cause cardiovascular complications due to the severely reduced DBP and increased pulse pressure.
