Chemical Heat Packs as an Intervention to Prolong Ultrasound Battery Runtime

Publication date: Available online 2 May 2019Source: Wilderness &Environmental MedicineAuthor(s): Steven Roy, Ryck K. Schielke, Daniel Haffey, Heather CoombsIntroductionPoint-of-care ultrasonography is a burgeoning field of practice and study. Although point-of-care ultrasonography has started to penetrate the field of wilderness medicine, its use in cold environments is often limited by poor battery performance. In the current study, we investigated the effect of chemical foot warmers on battery runtime of handheld ultrasound machines in cold weather.MethodsThis prospective study used a balanced, crossover randomization design to compare handheld ultrasound machines exposed to cold weather with and without the application of chemical foot warmers. Time to power off, ambient temperature, air humidity, and wind speed were recorded for each trial and compared in a mixed-effects model analysis of variance.ResultsUltrasound machines showed significantly decreased functional battery life with decreasing temperature (P

ReinholdAbstractUterine leiomyomas, the most frequent benign myomatous tumors of the uterus, often cannot be distinguished from malignant uterine leiomyosarcomas using clinical criteria. Furthermore, imaging differentiation between both entities is frequently challenging due to their potential overlapping features. Because a suspected leiomyoma is often managed conservatively or with minimally invasive treatments, the misdiagno...

Authors: Jiang T, Zhao Q, Tian G, Chen X, Wu L Abstract Metastatic retroperitoneal tumors constitute an end-stage disease with poor prognosis that represents a heavy global health burden. The present study aimed to explore the efficacy of irreversible electroporation ablation (IRE) therapy in patients with end-stage retroperitoneal tumors. Between April 2016 and September 2017, three patients with unresectable retroperitoneal malignant tumors were enrolled. Among these cases, ultrasound (US)-guided IRE was palliatively performed for targeting 3 tumors (1 tumor per patient) located around the abdominal aorta. Post-t...

In conclusion, osteoporosis is prevalent among RA patients, as a part of a complex transformation of body mass composition, involving BMI and fat mass. The novel QUS scanning technique was able to replicate the results of the established DXA measurement of BMD and is potentially suitable for screening wide populations for osteoporosis.

Conclusions: In this survey of doctors attending point-of-care ultrasound short-courses in Australasia, the majority of doctors did not attain competence. However, the practice of unsupervised point-of-care ultrasound use by noncredentialled doctors was common. Further research into effective strategies to improve point-of-care ultrasound competence is required.

AbstractIntroductionTo explore the strength of association and the diagnostic accuracy of umbilical (UA), middle cerebral (MCA), uterine arteries pulsatility index (PI) and cerebroplacental ratio in predicting adverse outcome when applied to singleton pregnancies at term.Material and methodsProspective study carried out in a dedicated research ultrasound clinic. Attended clinicians were blinded to Doppler findings. Inclusion criteria were consecutive singleton pregnancies between 36+0 and 37+6 weeks of gestation. The primary outcome was a composite score of adverse perinatal outcome. Logistic regression and ROC curve analy...

Conclusions: PMR is characterized by an important chronic subclinical inflammatory component. This pilot study demonstrates that affected patients show endothelial dysfunction that slowly responds to steroid therapy. Further studies are needed to investigate the clinical relevance of these observations and, in particular, to monitor the cardiovascular risk profile of PMR patients.

ConclusionCEUS is a minimally invasive and useful diagnostic method that can be used to make a simple and quick qualitative diagnosis of pancreatic diseases. CEUS provides a lot of information important for diagnosis, and has led to changes in the conventional diagnostic systems in pancreatic diseases.

CONCLUSIONS: In the rural context, POCUS AAA is a reliable 'rule out' test for ruptured abdominal aortic aneurysm and FAST scan has a role as a 'rule in' test for solid organ injury. These findings are consistent with larger studies in the emergency medicine literature. PMID: 31401838 [PubMed - in process]
