Neck pain in the pediatric population has a broad differential diagnosis, ranging from benign to imminently life-threatening causes. Trauma and infection represent the most common etiologies of pediatric neck pain in the pediatric emergency department (PED) setting. Malignancy, though a rare cause of pediatric neck pain, is important to consider in patients with acquired torticollis or focal neurologic signs. ⋯ We describe the case of a previously healthy 12-year-old female who presented to the PED with neck pain radiating down her upper extremities. The physical examination revealed diminished strength in her upper extremities compared to her lower extremities. Further evaluation revealed lymphadenopathy in the cervical and mediastinal areas and an epidural tumor in the cervical spinal column. The ultimate diagnosis was Hodgkin lymphoma presenting in an unusual manner with cervical spinal cord compression. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Neck pain is a common chief complaint among pediatric patients in the emergency setting. This case of spinal cord compression caused by malignancy illustrates the necessity of detailed spinal imaging in patients with neck pain and "red flag" signs, including but not limited to an abnormal neurologic examination.

Anti-N-methyl-d-aspartate (NMDA) receptor autoimmune encephalitis is a newly identified form of encephalitis whose incidence is on the rise. Awareness of this condition and symptom recognition are key to early diagnosis and prompt treatment, which may alter the course of the disease. ⋯ A 35-year-old woman presented to our Emergency Department (ED) with lethargy, bizarre behavior, agitation, confusion, memory deficits, and word-finding difficulties. Her symptoms and evaluation were potentially consistent with a primary psychiatric disorder, but the absence of frank psychosis and presence of neurologic features related to memory and cognition prompted other considerations. In the ED we performed a lumbar puncture, and in addition to routine studies, ordered anti-NMDAR antibody screening. The screening studies returned positive, leading to treatment with glucocorticoids and intravenous immune globulin and resulting in improvement to near baseline function. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Although anti-NMDAR encephalitis is relatively uncommon, reports of this previously unrecognized condition are increasing, with an unclear true incidence of disease. Emergency providers should consider this diagnosis in their differential for patients presenting with new neuropsychiatric symptoms, particularly in young women. Prompt treatment leads to near complete neurologic recovery in 75% of patients, whereas delays in diagnosis and treatment may be associated with worse outcomes including death.

Every emergency physician encounters acutely dyspneic patients with localized hyperlucency on chest x-ray study. Although most commonly due to pneumothorax, alternative diagnosis in selected cases with atypical features includes bullae and cystic lesions, especially in childhood. Presence of atypical radiology shouId alert an emergency physician to rule out any alternative diagnosis. Computed tomography is usually diagnostic in such cases and a double-wall sign on computed tomography aids to distinguish between pneumothorax and bullous disease. ⋯ A 60-year-old male presented with sudden increase in dyspnea and a localized hyperlucency on chest x-ray study. A review of his medical records and evaluation of atypical radiology by computed tomography revealed increase in size of bulla to be the cause for distress rather than a pneumothorax. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Every emergency physician encountering acutely dyspneic patients should be aware of these potential mimickers of pneumothorax and ways to distinguish them to avoid inadvertent tube thoracostomy and possible complications.

Infants are at risk for vitamin K deficiency bleeding (VKDB) because of limited stores of vitamin K (VK) at birth and a low concentration of VK in human breast milk. Therefore, the administration of intramuscular (IM) VK at birth has been recommended since 1961 in the United States. Infants who do not receive IM VK and who are exclusively breast-fed are at increased risk for VKDB. While VKDB is rare, a common presentation of late onset VKDB is intracranial hemorrhage. ⋯ We report the case of a 4-week-old infant who presented to the emergency department with lethargy and a grossly dilated right pupil. The parents denied trauma. A computed tomography scan revealed a right-sided subdural hematoma with midline shift. The infant's international normalized ratio was >10.9 and his prothrombin time PT was >120 seconds. VK was administered and the child was transferred to a tertiary care center for emergent neurosurgery. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: The difficult part of making this critical diagnosis is considering it. Any bleeding in a newborn without trauma should prompt inquiry regarding neonatal VK administration and a serum prothrombin time level. Fortunately, once the diagnosis is made, therapy in the emergency department can be lifesaving and is familiar to emergency physicians. Treatment parallels usual care for the adult with excess anticoagulation caused by warfarin. Prompt intravenous VK is universally accepted. Studies to support fresh frozen plasma or prothrombin complex concentrate are lacking but make good clinical sense for life-threatening bleeding.

In 2012, a voluntary certification program called Pediatric Prepared Emergency Care (PPEC) was established in Arizona as a system for pediatric emergency preparedness. Emergency medicine and pediatric specialists generated basic, intermediate, and advanced designation criteria. Dedicated medical management by a pediatric emergency specialist is required for advanced centers. Designation follows a site visit, review, and approval by the subcommittee and the Arizona Chapter of the American Academy of Pediatrics. ⋯ PPEC enhances the quality of pediatric emergency preparedness by means of voluntary certification. The primary limitations are sustainability and funding, because an Emergency Medical Services for Children grant has offset the cost until now. The number of member facilities in this designation system is continually growing, and universal recertification shows sustainability.
