RESUMO
OBJECTIVE: To evaluate the evidence and produce a summary and recommendations for the most common heart and lung point-of-care ultrasound (PoCUS). METHODS: We reviewed 10 clinical domains/questions related to common heart and lung applications of PoCUS.âFollowing review of the evidence, a summary and recommendations were produced, including assigning levels of evidence (LoE) and grading of recommendation, assessment, development, and evaluation (GRADE). 38 international experts, the expert review group (ERG), were invited to review the evidence presented for each question. A level of agreement of over 75â% was required to progress to the next section. The ERG then reviewed and indicated their level of agreement of the summary and recommendation for each question (using a 5-point Likert scale), which was approved in the case of a level of agreement of greater than 75â%. A level of agreement was defined as a summary of "strongly agree" and "agree" on the Likert scale responses. FINDINGS AND RECOMMENDATIONS: One question achieved a strong consensus for an assigned LoE of 3 and a weak GRADE recommendation (question 1), the remaining 9 questions achieved broad agreement with an assigned LoE of 4 and a weak GRADE recommendation (question 2), three achieved an LoE of 3 with a weak GRADE recommendation (questions 3-5), three achieved an LoE of 3 with a strong GRADE recommendation (questions 6-8) and the remaining two were assigned an LoE of 2 with a strong GRADE recommendation (questions 9 and 10). CONCLUSION: These consensus-derived recommendations should aid clinical practice and highlight areas of further research for PoCUS in acute settings.

The objective of this review is to assess the diagnostic accuracy of bedside-focused transthoracic echocardiography (TTE) in acute atraumatic thoracic aortic syndrome in adults. We performed a systematic review and meta-analysis of publications that described the use of bedside-focused TTE on adults presenting to the emergency care setting with suspected atraumatic thoracic aortic syndrome. Studies were identified using keyword and Medical Subject Heading searches on databases and grey literature, followed by abstract screening and study selection by two independent reviewers. Sixteen studies over six decades were included in the meta-analysis (nâ =â 4569 patients). The prevalence of Type A thoracic aortic dissection was 11% (range 1.4-45.7%) and Type B dissection was 7% (range 1.8-30.55%). Type A dissection through direct visualisation of an intimal flap on TTE (i.e. direct sign) pooled sensitivity and specificity were 89% [95% confidence interval (CI), 82-94%] and 92% (95% CI, 88-95%) respectively. For Type B dissection, the pooled sensitivity was 65% (95% CI, 45-80%) and specificity was 100% (95% CI, 0.69-100%). TTE indirect signs for dissection showed a pooled sensitivity of 64% (95% CI, 5.2-98.2%) and specificity of 94% (95% CI, 92-96.1%) for aortic valve regurgitation, a pooled sensitivity of 92% (95% CI 54-99.2%) and specificity of 87% (95% CI, 62-97%) for thoracic aortic aneurysm and a pooled sensitivity of 39% (95% CI 33.8-45%) and a specificity of 94% (95% CI, 92-95%) for pericardial effusion. In this systematic review and meta-analysis, bedside-focused TTE has a good specificity for Type A and B dissection, but poor sensitivity for Type B, and unclear for intramural haematoma and penetrating aortic ulcer.
RESUMO
Background: During the novel coronavirus disease 2019 (COVID-19) pandemic, rapid diagnostics have been frequently sought to quickly evaluate a patient's condition. Lung ultrasound can provide an early glimpse into the disease process and its severity. The addition of focused echocardiography can be particularly helpful in the haemodynamically compromised patient to detect myocardial involvement and alternative diagnoses. Case: We discuss here a 53-year-old patient who presented to the Emergency Department with hypoxia and hypotension. Bedside focused ultrasound revealed signs of COVID-19 pneumonia with evidence of right ventricular strain, initially thought to be due to massive pulmonary embolism. A computed tomography scan confirmed the findings on ultrasonography, but surprisingly did not demonstrate a pulmonary embolism. Conclusion: Point-of-care ultrasound in COVID-19 aided the diagnosis of affected organs and helped categorise the type of shock in this patient; however, right ventricular dysfunction should be interpreted with caution and may not be due to a pulmonary embolism, as in this case.
RESUMO
Gastrointestinal (GI) metastasis from a primary breast carcinoma is uncommon, with the rectum being one of the least reported sites in the literature. We report a case of a 79-year-old woman who underwent treatment for an infiltrative lobular carcinoma of the right breast with nodal involvement, and 10 years later developed recurrence in the form of rectal metastasis. Spread to the GI tract is most commonly seen with lobular breast carcinomas. Any patient with a history of breast cancer presenting typically or atypically with abdominal symptoms or altered bowel habit should raise a high index of suspicion for recurrent or metastatic disease.
