Barotrauma - StatPearls
Battisti, A. et. al.

Mar 11th, 2019 - Barotrauma is physical tissue damage caused by a pressure difference between an unvented space inside the body and surrounding gas or fluid. The damage is due to shear or overstretching of tissues. As a gas-filled space expands or contracts, it can cause damage to the local tissue. Occasionally, tears in tissue can allow gas to enter the body through the initial trauma site. This causes potenti...

ACR Appropriateness Criteria® : Chest Pain Suggestive of Acute Coronary Syndrome

Dec 31st, 2010 - Acute chest pain is a frequent presenting complaint in emergency departments. Along with other important disease entities such as aortic dissection and pulmonary embolus, such patient symptoms may question the possibility of acute myocardial ischemia. Acute coronary syndromes (ACS) include ST-segment elevation myocardial infarction (STEMI), non-STEMI (NSTEMI), and unstable angina (UA) [1]. B...

Resting Heart Rate in Cardiovascular Disease
Journal of the American College of Cardiology;

Dec 11th, 2006 - The importance of resting heart rate (HR) as a prognostic factor and potential therapeutic target is not yet generally accepted. Recent large epidemiologic studies have confirmed earlier studies that showed resting HR to be an independent predictor of cardiovascular and all-cause mortality in men and women with and without diagnosed cardiovascular disease. Clinical trial data suggest that HR re...

Rene Theophile Hyacinthe Laennec (1781–1826): The Man Behind the Stethoscope
Clinical Medical Research; Roguin, A.

Aug 30th, 2006 - Rene Theophile Hyacinthe Laënnec (1781–1826) was a French physician who, in 1816, invented the stethoscope. Using this new instrument, he investigated the sounds made by the heart and lungs and determined that his diagnoses were supported by the observations made during autopsies. Laënnec later published the first seminal work on the use of listening to body sounds, De L’auscultation Mediate (O...

When Coronary CTA Is Most Appropriate for Suspected Heart Disease

Jun 21st, 2019 - NEW YORK (Reuters Health) - New research helps zero in on which patients with suspected coronary artery disease (CAD) will derive the most benefit from coronary computed tomography angiography (CTA). "Our results indicate that the accuracy of coronary CTA is highest for clinical decision making if probability of coronary disease is between 7% and 67%," lead authors Dr. Robert Haase and Dr Marc ...

Cognitive Decline May Accelerate After Ischemic Events

Jun 18th, 2019 - After a diagnosis of myocardial infarction (MI) or angina pectoris, individuals enrolled in the English Longitudinal Study of Aging (ELSA) showed more accelerated cognitive decline than those who remained free of coronary heart disease (CHD). The findings, published in the June 25 issue of the Journal of the American College of Cardiology, also showed that the cognitive deterioration occurred n...

Israel's Zebra Medical gets FDA ok for brain bleeds product

Jun 17th, 2019 - TEL AVIV (Reuters) - Zebra Medical Vision, an Israel medical imaging analytics company, said on Monday it received its third clearance from the U.S. Food and Drug Administration for its alert for intracranial hemorrhage, based on head CT scans.

Structured Approach to Venous Access Associated with Zero Risk of Pneumothorax During Cardiac Device Implant Procedures
Benjamin Carmel, Indiresha R. Iyer, MD

Jun 4th, 2019 - Iatrogenic pneumothorax, an acute serious complication, is reported to occur in 0. 1% to 2% of permanent trans-venous cardiac device implant procedures.

Is chest radiography routinely needed after thoracentesis?
Aibek E. Mirrakhimov, MD, Aram Barbaryan, MD et. al.

Jun 3rd, 2019 - No. After thoracentesis, chest radiography or another lung imaging study should be done only if pneumothorax is suspected, if thoracentesis requires more than 1 attempt, if the patient is on mechanical ventilation or has pre-existing lung disease, or if a large volume (> 1,500 mL) of fluid is removed.

Excision of abdominal wall endometriosis
Chetna Arora, MD, Patricia J. Mattingly, MD et. al.

May 28th, 2019 - Endometriosis, defined by the ectopic growth of functioning endometrial glands and stroma,1,2 usually affects the peritoneal cavity. However, endometriosis has been identified in the pneumothorax, brain, and within the extraperitoneum, such as the abdominal wall.

Antiangiogenics linked to fatal bleeds after RT in patients with “ultracentral” lung tumors
Andrew D. Bowser

May 18th, 2019 - In patients with tumors bordering the central airway, use of antiangiogenic agents has been linked to fatal hemorrhage after radiation treatment, according to investigators reporting a large, retrospective case series. Most hemorrhagic events in these patients with so-called “ultracentral” lung tumors occurred in those who received bevacizumab or pazopanib within 30 days of stereotactic body ra.

Respiratory effects may account for worse survival in women undergoing DTA and TAAA repair
Mark S. Lesney

May 14th, 2019 - Women undergoing open descending thoracic aortic aneurysm (DTA) and open thoracoabdominal aortic aneurysm (TAAA) repair are not at greater risk for operative mortality than their male counterparts. However, they are at significantly greater risk for major adverse events and have significantly lower 5-year survival, according to the results of a single institution database review of 738 surgery.

Crowdsourced AI Learns to Target Lung Tumors for Radiation

Apr 21st, 2019 - (Reuters Health) - In many parts of the world there are not enough radiation oncologists to design and deliver radiation treatments for lung cancer patients, but that gap could one day be filled with the help of artificial intelligence, researchers suggest in a new study. In a novel approach to the problem, the authors turned to crowdsourcing to help them develop a computer algorithm that would...
