for early detection of radiation-induced skin injury on the hands.
Orthopedic surgeons, particularly spine surgeons, should be regularly examined by dermatologists early in their careers for early detection of radiation-induced skin injury on the hands.
It has been previously reported that manual calf massage and passive ankle motion after total hip arthroplasty could reduce the incidence of venous thromboembolism. However, a combination of chemical and mechanical prophylaxes was employed. In this study, we aimed to examine the effect of mechanical prevention without pharmacological antithrombotic intervention.
Of the 313 patients who underwent unilateral primary total hip arthroplasty and received passive ankle motion and calf massage postoperatively at our hospital between January 2015 and December 2019, 261 (58 men, 203 women; mean age 62.1 years) were included in this retrospective study. Pharmacological anticoagulation therapy was administered in 176 patients (combination group); 137 patients only underwent calf massage and passive ankle motion without anticoagulation therapy (single group). The study outcomes were operation time, the incidence of deep vein thrombosis, pulmonary thromboembolism, intraoperative bleeding, estimated actual blood loss, atients without deep vein thrombosis before total hip arthroplasty.
Postoperative anticoagulant therapy does not have to be routinely used if mechanical prophylaxis is performed in patients without deep vein thrombosis before total hip arthroplasty.
Distal radius fractures are often the first fractures experienced by adults with osteoporosis, and such fractures provide an opportunity for treatment to prevent a domino effect of future fractures. Most of these fractures result from falls, which may be related to the individual's limb muscle mass, strength, and exercise capacity. Active vitamin D3 positively affects muscle and bone mass. However, the effect of a bone resorption inhibitor is unknown. This study aimed to determine the effects of eldecalcitol alone or a bone resorption inhibitor with eldecalcitol on bone mass, limb muscle mass, and exercise capacity of osteoporotic patients with distal radius fractures and to identify the preventive effects against future fractures.
Participants were postmenopausal women(n=99) with distal radius fractures who visited the orthopedics outpatient department in a city general hospital from April 2015 to October 2017. Bone mass, limb muscle mass, skeletal muscle mass index, and muscle strength (grip strength anesorption inhibitor with eldecalcitol improved bone mass and bone mineral density, and maintained skeletal muscle mass index, muscle strength, and exercise capacity of osteoporotic patients with distal radius fractures.
Radiation therapy plans are assessed using dose volume metrics derived from clinical toxicity and outcome data. In this study, plans for patients with locally advanced non-small cell lung cancer (LA-NSCLC) are examined in the context of the implementation of the Acuros XB (AXB) dose calculation algorithm focussing on the impact on common metrics.
Volumetric modulated arc therapy (VMAT) plans were generated for twenty patients, using the Analytical Anisotropic Algorithm (AAA) and recalculated with AXB for both dose to water (D
) and dose to medium (D
). Standard dose volume histogram (DVH) metrics for both targets and organs-at-risk (OARs) were extracted, in addition to tumour control probability (TCP) for targets.
Mean dose to the planning target volume (PTV) was not clinically different between the algorithms (within ±1.1Gy) but differences were seen in the minimum dose, D
and D
as well as for conformity and homogeneity metrics. A difference in TCP was seen for AXB
plans versus both AXB
and AAA plans. No clinically relevant differences were seen in the lung metrics. For point doses to spinal cord and oesophagus, the AXB
values were lower than AXB
, by up to 1.0Gy.
Normalisation of plans to the mean/median dose to the target does not need to be adjusted when moving from AAA to AXB. OAR point doses may decrease by up to 1Gy with AXB
, which can be accounted for in clinical planning. Other OAR metrics do not need to be adjusted.
Normalisation of plans to the mean/median dose to the target does not need to be adjusted when moving from AAA to AXB. OAR point doses may decrease by up to 1 Gy with AXBDm, which can be accounted for in clinical planning. Other OAR metrics do not need to be adjusted.This study aims to quantitatively evaluate the effect of additional copper-filters (Cu-filters) on the radiation dose and contrast-to-noise ratio (CNR) in a dental cone beam computed tomography (CBCT). The Cu-filter thickness and tube voltage of the CBCT unit were varied in the range of 0.00-0.20 mm and 70-90 kV, respectively. The CBCT images of a phantom with homogeneous materials of aluminum, air, and bone equivalent material (BEM) were acquired. The CNRs were calculated from the voxel values of each homogeneous material. The CTDIvol was measured using standard polymethyl methacrylate CTDI test objects. We evaluated and analyzed the effects of tube current and various radiation qualities on the CNRs and CTDIvol. We observed a tendency for higher CNR at increasing tube voltage and tube current in all the homogeneous materials. On the other hand, the CNR reduced at increasing Cu-filter thickness. The tube voltage of 90 kV showed a clear advantage in the tube current-CNR curves in all the homogeneous materials. The CTDIvol increased as the tube voltage and tube current increased and decreased with the increase in the Cu-filter thickness. When the CNR was fixed at 9.23 of BEM at an exposure setting of 90 kV/5 mA without a Cu-filter, the CTDIvol at 90 kV with Cu-filters was 8.7% lower compared with that at 90 kV without a Cu-filter. The results from this study demonstrate the potential of adding a Cu-filter for patient dose reduction while ensuring the image quality.Developmental and epileptic encephalopathies are a group of rare, severe epilepsies, which are characterized by refractory seizures starting in infancy or childhood and developmental delay or regression. Developmental changes might be independent of epilepsy. However, interictal epileptic activity and seizures can further deteriorate cognition and behavior. Recently, the concept of developmental and epileptic encephalopathies has moved from the lesions associated with epileptic encephalopathies toward the epileptic network dysfunctions on the functioning of the brain. selleck Early recognition and differentiation of patients with developmental and epileptic encephalopathies is important, as precision therapies need to be holistic to address the often devastating symptoms. In this review, we discuss the evolution of the concept of developmental and epileptic encephalopathies in recent years, as well as the current understanding of the genetic basis of developmental and epileptic encephalopathies. Finally, we will discuss the role of epileptic network dysfunctions on prognosis for these severe conditions.
