I came to work one day and one of my partners said, "Hey, Steve, we had a STEMI this afternoon!" I said, "Cool, can I see the ECG?' Of course he said: "Yes, it was a 60 year old diabetic with Chest pain." So he showed me the ECG recorded in triage: What did I say? "That is not a STEMI. That is Arterial Pulse Tapping Artifact (APTA)." He said: "What?

Well, PRISMS demonstrated unfavorable results. MARISS tried to ascertain predictors of poor outcome in mild stroke, and intravenous thrombolysis was not associated with an effect on the primary outcome. Now, again, we examine thrombolysis in “mild” stroke, in this case, NIHSS ≤3 – and fail. Like MARISS, this is a retrospective dredge of patients selected by the treating clinicians to receive either intravenous thrombolysis or, in this case, dual-antiplatelet therapy with clopidogrel
5-year-old Willow arrives in the ED at 3 a.m. Her mum says she has been waking up screaming on the last few nights, clutching her vulval area and saying it hurts. Her parents have noticed she is scratching her bottom a lot, too, and they’ve had an email from school saying there are cases of threadworms in the reception class. Threadworms ( Enterobius vermicularis , also known as pinworms or seatworms) are the most common helminthic infection in the Western World.
When American Physician Partners (APP) of Brentwood, Tenn., one of the country’s largest physician staffing firms, announced on July 17 through an email to its employees its intention to cease operations July 31, the chilling effects were felt across a workforce of 2,500 APP-employed physicians and advanced practice clinicians working at the 153 hospital emergency departments it managed in 18 states.
Take Home Points: Airway management is paramount; expect a challenging intubation and consider controlling the airway early if there is apparent airway compromise. Understanding the cause of angioedema (mast cell vs. bradykinin mediated) helps dictate directed management. Urticaria and pruritus = MAST CELL mediated, which is treated like a standard allergic reaction.

Answers: Question 1 answer: PH = 7.315, that is mild acidaemia. pCO2 = 48 mmHg. For venous blood, pCO2 level up to 48 mmHg is considered normal (40 for arterial blood).
Researchers at the University of California San Francisco have developed a brain computer interface that can lets someone with severe paralysis communicate with both speech and facial expressions, in the form of a digital avatar. The breakthrough advances what has been possible, with previous brain computer interface systems providing speech only, and allows people to communicate more completely, encompassing facial expressions, which are an important aspect of natural communication.
This month I am back on the SGEM podcast – this time on the all new Paeds section with Dr Dennis Ren. In this episode we do a deep dive into the BUCKLED trial that looked at the use of bedside ultrasound vs. plain film X-rays for the initial investigation of paediatric forearm fractures. This is a really neat Australian trial run by my friend Dr Peter Snelling and friends in Queensland.
Researchers at the Harvard Wyss Institute have developed a technique that lets clinicians to characterize and monitor melanoma. The system involves using a microneedle patch that can draw deep interstitial fluid into itself through a series of penetrating hyaluronic acid needles. The needles can later be dissolved to release the biomarkers into a test tube before analysis, using a highly sensitive technique called Simoa, to detect individual biomarker protein molecules.
Sent by anonymous, edited by Pendell Meyers A man in his 50s with history only of hypertension presented with acute chest pain that started 45 minutes prior to presentation while doing yard work. It radiated to both shoulders and both upper extremities, and there was shortness of breath and diaphoresis as well. He reported a normal stress test a few years ago.

Researchers at the National University of Singapore have developed a highly sensitive pressure sensor that can provide haptic feedback for surgeons using laparoscopic tools or for use in robotic grippers as part of robotic surgical systems. The technology is inspired by the surface of the lotus leaf, which is extremely sensitive to the pressure exerted by tiny drops of water and will repel them.
A 40 year old with nonspecific symptoms including dizziness. What do you notice about the ECG? There is a very short QT interval. This is often found in hypercalcemia. See Ken Grauer's comments below for detail. Thus, the patient's chemistry was done and revealed ionized hypercalcemia of 6.3 mg/dL (normal 4.4 - 5.2) Followup: he was found to have hyperparathyroidism == MY Comment , by K EN G RAUER, MD ( 9/12 /2023 ): == Today's ECG is remarkable for an uncommon but important finding that we peri
Background: Point of care ultrasound (POCUS) has a demonstrated sensitivity of 89.8% and specificity of 88.0% for identification of cholelithiasis and has a proven negative predictive value for ruling out other acute biliary pathology such as acute cholecystitis. 1 It is a quickly deployable and easily interpreted study that can be done in real time to guide decisions in the Emergency Department.
Researchers at Stanford University have developed a new type of cancer therapy. The technology targets mucins, sugar-coated proteins that help cancer cells to metastasize and avoid the immune system. In particular, mucins enable cancer cells to survive free-floating as they travel through the blood during metastasis and can also trick immune cells into assuming that the cancer cell is not a threat.
On April 14, 2023 I suffered a life-threatening massive pulmonary embolus. I had a DVT that I had ignored/rationalized for nearly a year that turned out to extend from my mid-calf to lower thigh, and on April 14 a big chunk of it broke loose and tried to kill me. I had major clots in.
Answer: The correct answer is retropharyngeal abscess (d). A retropharyngeal abscess (RPA) is an uncommon but serious life-threatening infection that results from a purulent infection in the retropharyngeal space. It may be seen in all ages but most commonly occurs in children aged two to five years. A retropharyngeal abscess usually occurs after an antecedent viral upper respiratory illness that results in a suppurative cervical adenitis that then extends to involve the retropharyngeal space.
There’s no denying that human imagination is a powerful thing. It has led us to create incredible works of art, literature that transports its readers to other realms, technology that revolutionizes the way we communicate and travel, music and film that makes us laugh, cry, and hit repeat. But our imagination often falls short when trying to conceive of the world from another person’s perspective, especially when it comes to senses.
Researchers at the University of Edinburgh have developed a new method to create multilayered tubes from cells. The technique could be very useful for recreating multilayered tubular constructs that are found in the body, such as the intestines and blood vessels. Accurately modeling such complex structures in the lab could open new doors in terms of medical research and may even pave the way for bioengineered intestinal or vascular constructs that are suitable for implantation in human patients.
A confluence of challenges is renewing the urgency to address one of emergency medicine’s seemingly intractable issues: boarding in the emergency department.
