A 51-year-old man presented with a 5-day history of progressive facial swelling, sensation of head fullness, increasing shortness of breath and paroxysmal nocturnal dyspnea. He denied chest pain, syncope or presyncope. Past medical history included mechanical aortic valve replacement 7 years prior and atrial fibrillation treated with warfarin. ⋯ Acute type A aortic dissection (AD) is an emergency requiring prompt diagnosis and treatment. Patients typically present with acute onset of chest and/or back pain, classically described as "ripping" or "tearing." SVC syndrome is rarely, if ever, mentioned as a presentation, as it is usually due to more chronic conditions. This case illustrates a rare incidence of type A AD actually presenting as SVC syndrome.

ABSTRACTIntroduction:Emergency department (ED) crowding is a significant problem in Canada and has been associated with decreased quality of care in general and pediatric emergency departments (PEDs). Although boarding of admitted patients in the ED is the main contributor to adult ED overcrowding, factors involved in PED crowding may be different. The objective of this study was to report the trend in PED services use and to document the degree of overcrowding experienced in a Canadian PED. ⋯ LWBS proportions among CTAS 3, CTAS 4, and CTAS 5 groups and LOS for all CTAS groups progressively and statistically increased from year to year. Conclusions:Over the course of the study period, there was a substantial increase in PED visits, which likely contributed to the worsening markers of PED flow outcomes. Further study into the effects of PED crowding on patient outcomes is warranted.

Spontaneous low cerebrospinal fluid pressure headache: an emergency medicine perspective.
Spontaneous low cerebrospinal fluid pressure headaches are a rare but treatable cause of debilitating headaches. The condition is characterized by a postural headache in the absence of any recent spinal procedures and is exacerbated when upright and relieved when supine. Diagnosis and treatment are often delayed, however, due to a lack of recognition and awareness, as illustrated by this case report of a patient who had multiple emergency department visits before further investigations were sought.

ABSTRACTHypokalemic periodic paralysis is the most common form of periodic paralysis and is characterized by attacks of muscle paralysis associated with a low serum potassium (K+) level due to an acute intracellular shifting. Thyrotoxic periodic paralysis (TPP), characterized by the triad of muscle paralysis, acute hypokalemia, and hyperthyroidism, is one cause of hypokalemic periodic paralysis. The triggering of an attack of undiagnosed TPP by β2-adrenergic bronchodilators has, to our knowledge, not been reported previously. ⋯ One patient developed hyperkalemia after a total potassium chloride supplementation of 110 mmol. Thyroid function testing was diagnostic of primary hyperthyroidism due to Graves disease in both cases. These cases illustrate that β2-adrenergic bronchodilators should be considered a potential precipitant of TPP.

To determine whether novices can distinguish between properly and improperly placed guidewires in a vascular access model after only minimal training. ⋯ Sonographic guidewire visualization, a step recommended for ensuring proper vessel cannulation during central venous access, can be accomplished by novices with a high degree of accuracy.
