Paraphimosis is an acute urological emergency occurring in uncircumcised males that can lead to strangulation of the glans and painful vascular compromise. Ketamine has been used in the emergency department (ED) as an anesthetic agent for procedural sedation, and when administrated in a sub-dissociative dose (low dose) at 0.1-0.3 mg/kg, ketamine has been utilized in the ED and prehospital settings for pain control as an adjunct and as an alternative to opioid, as well as for preprocedural sedation. This report details the case of a pediatric patient who presented to our Pediatric ED with paraphimosis and had his procedural pain treated with ketamine administrated via a breath-actuated nebulizer (BAN). ⋯ This case report illustrates the potential use of ketamine via BAN to effectively achieve minimal sedation for a procedure in pediatric patients in the ED. The patient was a 15-year-old boy admitted to the Pediatric ED complaining of groin pain due to paraphimosis. The patient was given 0.75 mg/kg of nebulized ketamine via BAN, and 15 min after the medication administration the pain score was reduced from 5 to 1 on the numeric pain rating scale. The patient underwent a successful paraphimosis reduction without additional analgesic or sedative agents 20 min after the administration of nebulized ketamine. The patient was subsequently discharged home after 60 min of monitoring, with a pain score of 0. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: The use of nebulized ketamine via BAN might represent a viable, noninvasive way to provide a mild sedative and be an effective analgesic option for managing a variety of acute painful conditions and procedures in the pediatric ED.

Intramuscular (i.m.) injections are a commonly utilized route for medication delivery. Intramuscular-associated soft tissue infections are rare and can include pyomyositis and i.m. abscess. Intramuscular testosterone injections have not been previously implicated in causing pyomyositis. Point-of-care ultrasound is an important bedside tool that can identify pyomyositis and differentiate this infection from more common entities such as cellulitis. ⋯ We present two cases of i.m. testosterone-associated pyomyositis. In both cases, the physical examination features were consistent with simple cellulitis. However, point-of-care ultrasound evaluation revealed changes consistent with pyomyositis in each case. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Although uncommon, i.m. injections such as testosterone carry a risk of soft tissue infection. As demonstrated in the above cases, ultrasound can be helpful in making the differentiation between simple cellulitis and pyomyositis. The emergency physician should be cognizant of this complication of therapeutic i.m. injections, as well as the diagnostic efficacy of point-of-care ultrasound in evaluating the extent and location of the soft tissue infection.

The Proteeae group (i.e., Proteus species, Morganella morganii, and Providencia species) frequently causes urinary tract infections (UTIs) and is generally resistant to nitrofurantoin. Proteeae species can produce urease, which can increase urine pH. ⋯ Urine pH of 8 or higher is associated with high rates of nitrofurantoin resistance.

Observational Study
Chest Compression Fraction Alone Does Not Adequately Measure Cardiopulmonary Resuscitation Quality in Out-of-Hospital Cardiac Arrest.
High-quality cardiopulmonary resuscitation in out-of-hospital cardiac arrest is important for increased survival and improved neurological outcome. Chest compression fraction measures the proportion of time chest compressions are given during a cardiac arrest resuscitation. Chest compression fraction has not been compared with the quality of chest compressions delivered at the recommended rate and depth of 100-120/min and 2.0-2.4 inches, respectively. ⋯ Chest compression fraction is not associated with compressions in target for rate and depth for out-of-hospital cardiac arrest cardiopulmonary resuscitation.

Head injuries are an important cause of morbidity and mortality in children and young adults. There are multiple sight-threatening complications of head injury, even in closed head injury without visible violation of the globe or orbits. One such entity is traumatic optic neuropathy. ⋯ Herein we describe a case of traumatic optic neuropathy in an otherwise healthy teenage patient who suffered total monocular vision loss after a fall and without any other injuries on examination. Unfortunately, the prognosis for this condition is relatively poor in terms of visual recovery. Though much research has been conducted attempting to treat this condition, to date there have been no studies showing a clear benefit of medical or surgical intervention. Why Should an Emergency Physician Be Aware of This? Although there is no proven treatment for traumatic optic neuropathy, emergency physicians may encounter this in their practice while caring for both pediatric and adult patients presenting with head injury. Having more background knowledge on this condition will enhance emergency physicians' ability to consult with subspecialist providers as well as to educate patients and their families on their condition and prognosis.
