Exposure to the undersea environment has unique effects on normal physiology and can result in unique disorders that require an understanding of the effects of pressure and inert gas supersaturation on organ function and knowledge of the appropriate therapies, which can include recompression in a hyperbaric chamber. The effects of Boyle's law result in changes in volume of gas-containing spaces when exposed to the increased pressure underwater. These effects can cause middle ear and sinus injury and lung barotrauma due to lung overexpansion during ascent from depth. ⋯ Usual therapy is recompression in a hyperbaric chamber following well-established protocols. Many recreational diving candidates seek medical clearance for diving, and healthcare providers must be knowledgeable of the environmental exposure and its effects on physiologic function to properly assess individuals for fitness to dive. This review provides a basis for understanding the diving environment and its accompanying disorders and provides a basis for assessment of fitness for diving.

Randomized Controlled Trial Comparative Study
A Comparison of Cosmetic Outcomes of Lacerations on the Extremities and Trunk Using Absorbable Versus Nonabsorbable Sutures.
Use of absorbable sutures for simple laceration repair in the ED results in comparable 3 month cosmetic outcome to non-absorbable sutures.

Randomized Controlled Trial Multicenter Study
Does midazolam enhance pain control in prehospital management of traumatic severe pain?
Midazolam comedication with morphine is a routine practice in pre and postoperative patients but has not been evaluated in prehospital setting. We aimed to evaluate the comedication effect of midazolam in the prehospital traumatic adults. ⋯ According to our study, midazolam does not enhance pain control as an adjunctive to morphine regimen in the management of trauma-induced pain in prehospital setting. However, such midazolam use seems to be associated with an increase in drowsiness.

The use of computed tomographic scanning in blunt head trauma has increased dramatically in recent years without an accompanying rise in the prevalence of injury or hospital admission for serious conditions. Because computed tomography is neither harmless nor inexpensive, researchers have attempted to optimize utilization, largely through research that describes which clinical variables predict intracranial injury, and use this information to develop clinical decision instruments. Although such techniques may be useful when the benefits and harms of each strategy (neuroimaging vs observation) are quantifiable and amenable to comparison, the exact magnitude of these benefits and harms remains unknown in this clinical scenario. ⋯ We posit that elements unrelated to standard clinical factors, such as personality of the physician, fear of litigation and of missed diagnoses, patient expectations, and compensation method, may have equal or greater impact on actual decision making than traditional clinical factors. We believe that 3 particular factors deserve special consideration for further research: fear of error/malpractice, financial incentives, and patient engagement. Acknowledgement and study of these factors will be essential if we are to understand how emergency physicians truly make these decisions and how test-ordering behavior can be modified.
