Hashimoto's Encephalopathy (HE) is a rare form of autoimmune encephalopathy associated with Hashimoto's thyroiditis in which patients experience cognitive impairment and various neurologic symptoms. We present a case of a young female that presented to the emergency department with urinary retention, and was ultimately diagnosed with HE. Examination was significant for direction-changing and vertical nystagmus (direction-changing nystagmus describes a phenomenon where the fast beat changes with the direction of gaze), hyperreflexia, clonus, and Babinski and Hoffman's reflexes (all upper motor neuron (UMN) signs). ⋯ To our knowledge, urinary retention in the presence of other UMN signs has not been reported in association with HE; nor has this patient's type of nystagmus. Emergency physicians should be aware of this condition and can play an important role by considering it when neurologic findings are not explained by infectious, toxic, metabolic, or structural etiologies. Although relatively rare, if detected and treated early HE can have a good prognosis.

Case Reports
Spontaneous coronary artery dissection in a young woman with polycystic ovarian syndrome.
Polycystic ovarian syndrome (PCOS) affects 4% to 12% of women in reproductive age, representing a clinical condition that could predispose to cardiovascular diseases. We report a case of a 34-year-old woman with PCOS, presenting with chest pain, onset two days before, and ST segment-elevation myocardial infarction. ⋯ The patient was discharged in medical therapy after 5days. This is the first observation of spontaneous coronary artery dissection occurring in a PCOS patient.

A triad of circulatory collapse, right ventricular dilatation, and large alveolar dead space is proposed for the rapid diagnosis and treatment of massive pulmonary embolism. A 17year-old female on oral contraceptives collapsed at home becoming incoherent with shallow breathing. Paramedics initiated mechanical chest compression and transported the patient to our emergency department, arriving minimally responsive with undetectable blood pressure but having positive corneal reflexes and bradycardia with wide QRS. ⋯ A CT-angiogram showed the pulmonary arteries free of emboli but a thrombus in the right common iliac vein. The patient recovered fully and was discharged home on warfarin 8days later. Based on this and other reports, we propose a triad of circulatory collapse, right ventricular dilatation, and large alveolar dead space for the rapid diagnosis and treatment of massive pulmonary embolism, with systemic fibrinolysis as the first-line intervention.

Abdominal pain is common in children, but expeditious diagnosis of life- or organ-threatening diseases can be challenging. An evidence-based definition of tachycardia in children was established recently, but its diagnostic utility has not yet been studied. ⋯ Tachycardia significantly increased the likelihood of life- or organ-threatening diseases. Tachycardia in children with abdominal pain should alert emergency physicians to the possibility of serious illness.

Hyperthermia is a potentially life threatening scenario that may occur in patients due to accompanying morbidities, exertion, or exposure to dry and arid environmental conditions. In particular, heat stroke may result from environmental exposure combined with a lack of thermoregulation. Key clinical findings in the diagnosis of heatstroke are (1) a history of heat stress or exposure, (2) a rectal temperature greater than 40 °C, and (3) central nervous system dysfunction (altered mental state, disorientation, stupor, seizures, or coma) (Prendergast and Erickson, 2014 [1]). ⋯ Invasive approaches may include gastric lavage or peritoneal lavage (Schraga and Kates [4]). The efficacy of these methods vary and select treatment approaches may be unsuitable for specific individuals (Schraga and Kates [4]). In this work, the effectiveness of radiation cooling of individuals as a stand-alone treatment and comparisons with existing noninvasive techniques are presented.
