0 N, compared to 495.2 N for metal rings of all sizes. The average ultimate failure force of silicone rings in the clenched fist position was increased across rings of all sizes, with an average of 99.9 N. There were no degloving injuries in the silicone ring avulsion group.

Biomechanically, silicone rings have a significantly lower failure force than metal rings and may help prevent ring avulsion injuries.

The use of silicone rings should be encouraged in professions where ring avulsion injuries are more likely, such as heavy labor.

Distal radius fractures are the most common long bone fracture in the United States, with an estimated incidence of 640,000 cases per year. Operative fixation presents a theoretical risk factor for the development of upper-extremity venous thromboembolism (UE-VTE). Additionally, patients presenting with distal radius fracture commonly have preexisting comorbidities that further increase the risk of UE-VTE. Finally, UE-VTE is considered the highest risk for eventual development of pulmonary embolism. Despite this, scant attention has been paid to studying UE-VTE in this population. The purpose of this study was to measure the incidence of this complication and to identify possible medical factors that increased the risk of developing UE-VTE.

We queried the Truven MarketScan Commercial Claims and Encounters Database for all patients who experienced a distal radius fracture and were subsequently treated with open reduction and internal fixation between 2012 and 2016. Patients were identified using relevant Common Procedural Terminology codes. Demographic and medical variables were tabulated. Our primary outcome was the development of ipsilateral UE-VTE or pulmonary embolism in the first 60 days after surgery.

The study included 24,494 patients. The mean age was 50.7 years (range, 18-91), and 58% were women. There were 79 cases (0.3%) of UE-VTE and 19 cases of pulmonary embolism in the study population (24.1% of all UE-VTE cases; 0.08% of total sample). Multivariable logistic regression showed that coexisting heart failure and estrogen use were associated with increased risk of UE-VTE.

Although uncommon, the development of UE-VTE after open reduction and internal fixation for distal radius fractures is a concerning complication. Coexisting heart failure and estrogen use are associated with increased risk of UE-VTE.

Upper extremity trauma is common, however the provision of emergency call for hand trauma can be challenging for hospital systems and hand surgeons. Over the past decade, the American Society for Surgery of the Hand (ASSH) has developed the Hand Trauma Network and an Emergency Hand Care Committee to refine care for hand trauma patients.

The ASSH administered surveys to members about the provision of emergency hand call in 2010 and 2019. Demographic information was collected including surgeon age, years in practice, board certification, practice setting, and ACS trauma level. Other survey questions included willingness and obligation to take call, as well as barriers to providing emergency call. Financial aspects of call were also queried.

Survey responses were obtained from 672 surgeons in 2010 and 1005 surgeons in 2019. There was a decrease in surgeons with obligatory hand call from 2010 to 2019 (70% vs 50%, P < .05) and an increase in the number of surgeons not taking hand call in 2019 (34%) comparage or the number of hand surgeons providing emergency hand care.
The aim of this study was to evaluate the effectiveness of cryotherapy on the prevention of oral mucositis (OM) and on the oral pH value in patients with multiple myeloma undergoing autologous stem cell transplantation.

This nonrandomized controlled clinical trial was carried out in Bone Marrow Transplant Centers of three hospitals with total 32 patients. In addition to standard oral care, a total of 80 minutes of cryotherapy was applied to the experimental group. OM was assessed according to the World Health Organization's Oral Toxicity Scale before chemotherapy and for 21 days after chemotherapy (every day in the first 14 days, then every other day until the 21st day [if not discharged]).

According to the findings, cryotherapy did not change the incidence of oral OM, and neither affected the severity of nor decreased the duration of it. Oral pH value was found to be significantly different between the patient groups only before and 1 day after chemotherapy.

Cryotherapy is an inexpensive, easy-to-use method with no side effects; it would be beneficial to continue cryotherapy to prevent the development of OM in patients with cancer receiving drugs with a short half-life such as melphalan. It is also recommended to conduct further studies with different chemotherapy drugs with short half-lives to determine its effect on the prevention of OM development.

Our hypothesis was that structural changes in the insonated target would increase its index of reflectivity. The neck anterior muscle and common carotid artery (walls and lumen) were visualized by echography (17 MHz linear probe), and the radiofrequency signal along each vertical line was displayed. The limits of the radiofrequency data corresponding to each target (muscle, vessel wall) were determined from the B-mode image and radiofrequency trace. Each target's index of reflectivity was calculated as the proportion of backscattered energy to the whole backscattered energy along the line. N-acetylcysteine nmr After 6 mo in flight, the index of reflectivity increased significantly for both common carotid walls, while it remained unchanged for the neck muscle, carotid intima and lumen. The index of reflectivity provided additional information beyond traditional B-mode imaging.
