The motive of this study was to investigate the interaction between polymorphisms in the MDR1 gene and anesthetic effects following pediatric tonsillectomy. In total, 240 children undergoing tonsillectomy with preoperative propofol-remifentanil anesthesia were selected. Genomic DNA was extracted from the peripheral blood of children after operation, and the MDR1 gene polymorphisms of 2677 G>T/A, 1236 C>T and 3435 C>T were detected by direct sequencing. We tested mean arterial pressure, diastolic blood pressure, systolic blood pressure, and heart rate at several time-points: T0 (5 mins after the repose), T1 (0 min after tracheal intubation), T2 (5 mins after the tracheal intubation), T3 (0 min after the tonsillectomy), T4 (0 min after removal of the mouth-gag) and T5 (5 min after the extubation)...

A 61-year-old woman was admitted to our hospital with progressive dyspnea on exertion. Chest X-rays and computed tomography (CT) showed elevation of the left diaphragm and atelectasis of the left lung. Eventration of the diaphragm was performed. The redundant diaphragm was plicated with vertical mattress sutures and reinforced by the suturing of the remnant diaphragm to the diaphragm near to the chest wall. During the thoracoscopic procedures, thoracoscopic examination from a small part of the resected diaphragm was conducted simultaneously to ensure safety and avoid damage to intra-abdominal organs...

BACKGROUND: The volar approach is commonly used for plating intra-articular fractures of the distal radius. Despite this, certain fracture configurations are more suitable for dorsal plate fixation. This technique has not gained favour due to the reported high incidence of extensor tendon irritation and attrition ruptures. With the advent of lower profile plates this risk has decreased. METHODS: We report on forty-six cases performed in a tertiary hand centre between January 2011 and May 2014...

The basic emission process associated with positron emission tomography (PET) imaging is Poisson in nature. Reconstructed images inherit some aspects of this-regional variability is typically proportional to the regional mean. Iterative reconstruction using expectation-maximization (EM), widely used in clinical imaging now, imposes positivity constraints that impact noise properties. This paper is motivated by the analysis of data from a physical phantom study of a PET/CT scanner in routine clinical use. Both traditional filtered back-projection (FBP) and EM reconstructions of the images are considered...

AIM: Due to the limits of calcitonin, other markers are warranted to better manage medullary thyroid carcinoma patients, and procalcitonin has been reported as promising. Here we aimed to evaluate procalcitonin as a marker of medullary thyroid carcinoma in the post-treatment follow-up. METHODS: Medullary thyroid carcinoma patients previously treated by thyroidectomy were enrolled. After complete imaging work-up (i.e. ultrasonography, computed tomography, magnetic resonance and 18 FDG-PET-CT) we identified patients with structural recurrent/persistent medullary thyroid carcinoma (active medullary thyroid carcinoma) and subjects with no evidence of disease...
