Since the advent of modern antibiotic use, deep neck space infections have decreased in occurrence; however, when these infections take place, the complications can be life threatening.[1-4] Because of the unique compartments of the cervical fascia, deep neck space infections can range in severity and have the potential to extend into the mediastinum. Based on how the infection propagates, these infections have the potential to cause upper airway edema, airway obstruction, mediastinitis, internal jugular vein septic thrombophlebitis, sepsis and septic embolization.[1,2]
Deep neck space infections can develop from infections of the teeth, salivary glands, nasal cavity, paranasal sinuses, pharynx and adenotonsillar tissues.[1,2] In children, adenoids and tonsillar infections are the most common source as they create a drainage pathway through the retropharyngeal lymph nodes resulting in retropharyngeal, parapharyngeal and peritonisllar space infections.1 In adults, dentoalveolar infections are the most common source of infection. In particular, infections of the lower second and third molars are dangerous because their roots spread directly into the submandibular space. Other causes of deep neck space infections in adults include: pharyngitis, tonsillitis, sialoadenitis, trauma, foreing body ingestion, sinusitis, cervical lymphadenitis, middle ear infections, mastoid infections, and IV drug use.

On a recent whim I searched Google for “emergency medicine education fellowship” and “learning theory.” During this entirely non-rigorous search I found that most of the first forty hits were programs specifically mentioning their emphasis on teaching Adult Learning Theory. In fact, even most non-educators reading this have probably heard of ALT. I would wager, however, that you have not heard of Situated Cognition, Cognitive Apprenticeship, Social Learning Theory, or Sociocultural Theory.
Who cares? Why does this matter to the everyday practitioner? Why does this matter to emergency medicine (EM)? The answer lies in the often gross misinterpretation of Adult Learning Theory and the strong case that it does not qualify as legitimate theory, thus leaving learners and teachers selling each other short of the most effective education. Additionally, the medical education community is beginning to move away from emphasizing Adult Learning Theory, and it is important that EM practices education with the most accurate information possible.
This is a two-part series that will first explore the criticisms of ALT, and later offer a breadth of alternatives that together inform us well about how we (adults and children) learn.

Recently, I heard a quote that has summarized a large part of the emergency medicine practice I have experienced thus far. My attending said, “In a few years, ultrasound will be the new stethoscope.” What he was referring to is not only how popular ultrasound is becoming, but the necessity for physicians to be able to use ultrasound correctly. Ultrasound can help keep certain patients right where we want them, not in a CT scanner, but in our emergency room where we can adequately diagnose and treat them. Ask any physician in the hospital, the last place they want an unstable (or potentially unstable) patient is in the radiology suite. From the Focused Assessment with Sonography in Trauma (FAST) exam to a simple post void residual, ultrasound is a fantastic tool. In this article I will present a relatively newer type of ultrasound technique as an example showing how important this tool can be.

Thank you for your interest in submitting an article for the AAEM/RSA (American Academy of Emergency Medicine Resident and Student Association) blog. The AAEM/RSA Blog is intended to provide readers with a source for reliable, up-to-date, and concise information relevant to the practice of emergency medicine. It is also intended to serve as an introduction to the publication process for interested medical students and residents.
AAEM/RSA encourages submissions on any topic relevant to the practice of emergency medicine authored by medical students, residents, fellows, or attending physicians. It is ideal for medical students to collaborate on a submission with a resident or attending mentor, although it is not required.
We accept any article felt to be appropriate for the blog format, although most accepted submissions are review articles, case reports, clinical pearls, or residency/career insights. The blog is not intended to be a venue for publication of original research articles.
Submitted articles must not be under consideration for publication elsewhere. Articles previously published on a residency website or blog will be considered for peer review and publication on a case-by-case basis, with full disclosure and permissions. The AAEM/RSA blog does occasionally re-post articles previously published in AAEM publications (such as Modern Resident or Common Sense).
We ask that you review the information below to assist you in preparing your submission for publication on the blog.
Articles should be between approximately 500 and 1,000 words and can be presented either in paragraph format (example), outline format consisting partially of full-sentence text (example), or a combination (example). Articles closer to 500 than 1,000 words are preferred. The blog is intended to provide a synthesis of information for readers, thus articles should utilize at least three sources, preferably primary sources or peer reviewed review articles. Book chapter sources are discouraged.
Submit only content that you personally authored. Material from other authors must be attributed and can be submitted only with their permission.
Please write using standard English grammar and style. Please attempt to limit the use of abbreviations, and define all uncommon abbreviations with their first usage.
