Greetings now from Singapore (well a week late). This has been one of the highlights of the trip. By taking part in the Society for Emergency Medicine in Singapore (SEMS) Annual Scientific Meeting, I met many physicians from around South East Asia and beyond. By listening and speaking to such a diverse crowd at varying stages in the practice of Emergency Medicine, I have been able to gain a better appreciation of Emergency Medicine in general. The conference was a well organized, high quality conference which I came away with some educational pearls. In addition, taking part in the post-conference Winfocus sessions afterwards afforded me the opportunity to interact with other ultrasonography keeners. Great forum to exchange ideas and approaches to ultrasonography. The Korean dinner was real yummy too!

The conference and Winfocus course both took place in the beautiful surroundings of Khoo Teck Puat Hospital in Singapore. This is a new a great new facility with it's own lake for peaceful walks and tranquility steps away from the emergency department. Yes, that really is the waiting board -- 311 visits at 18:00 starting from 24:00 and only a 72 minute wait! Wow!

Dr. Michael Woo and Dr. Gaby Blecher
Another update from Down Under...I had the opportunity to spend the day with Dr. Gaby Blecher and the Emergency Registrars at Monash Medical Centre in Melbourne, Australia. It was wonderful to catch up with Dr. Blecher who did a research fellowship at UOttawa with Dr. Stiell and completed his thesis on Point-of-care ultrasonography for DVTs in ED patients. He is now incorporating PoCUS as part of clinical care for EPs at Monash Medical Centre. I was able to present the role of PoCUS in patients presenting with shortness of breath and take part in their journal club. Taking part in their POCUS meeting was enlightening as they have advanced their QA system and have strong collaborations with Radiology. This was an enthusiastic group with lots of ideas. Looking forward to sharing these ideas with you all and developing future collaborations. (Oh yeah, I have enjoyed the surf, sun, and food as well! :)
A 60 year old man presents with shortness of breath on exertion. You work him up, but chest x-ray, spirometry, ECG, and labs (troponin and D-dimer) are all normal. Send him home, I guess...
Have you considered occult pericardial effusion? I have diagnosed about six unexpected pericardial effusions in the last year, and I have learned a few lessons:
1) this is not as rare a diagnosis as you think
2) patients can look really good, even with impending tamponade
This is an easy diagnosis to miss, but in 2013, I don't think that's acceptable anymore. Any well-trained emergency physician should be thinking about it and has a tool at hand to make the diagnosis quickly and cheaply.
The first video here is in the subxiphoid view.
The next video is the same patient, showing the effusion in the parasternal long.
The third video is from a different patient. Notice here how the right ventricular wall is collapsing inward at end-diastole. This is an echocardiograhic sign of tamponade. For the clinician, tamponade should be a clinical diagnosis, but if you see this at the bedside, be worried!
Occult pericardial effusion is not hard to diagnose. You just need to think of it, and be liberal in your use of PoCUS. Unexplained dyspnea, weakness, hypotension, or tachycardia? Get out your probe!

Greetings from Melbourne, Australia.
One of the great things about academic emergency medicine is the opportunity to travel and meet other interesting emergency physicians. I had the opportunity to attend journal club with staff and emergency registrars as well as share a presentation on the role of PoCUS in patients presenting with shortness of breath. It was wonderful to share ideas and learn the different approaches to emergency care. The Alfred Hospital is the major trauma centre in Melbourne and a fantastic facility. Thank you to my hosts and I look forward to collaborating on projects in the future!
