The common toxicities of cement are allergic dermatitis, abrasions, and chemical burns, but reports of cement ingestion are rare. In this study, we report a case of successful treatment of cement ingestion using emergency gastrointestinal endoscopy. ⋯ An 83-year-old female was admitted to the emergency department with altered mental state and abdominal pain. We assumed that she ingested cement based on her medical history and radiologic examination. A previous report recommended surgical removal with gastric lavage. However, we thought that wet cement is highly alkaline, and gastric lavage is contraindicated. We performed emergency gastrointestinal endoscopy, instead of gastric lavage. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: If a patient ingests cement, the recommendation is to check the status of the upper gastrointestinal tract and remove the cement by emergency gastrointestinal endoscopy as soon as possible.

The incidence of cardiac pacemaker implantation has risen markedly in the past three decades, making awareness of possible postprocedural complications critical to the emergency physician. This case is the first documented instance of internal jugular (IJ) deep vein thrombosis (DVT) from an uncomplicated pacemaker generator replacement. ⋯ A patient presented to an Emergency Department with a 2-day history of mild left temporal headache migrating to his left neck. The patient did not volunteer this information, but review of systems revealed a temporary transvenous pacemaker inserted through the right IJ vein 1 week previously during a routine exchange of a left-sided cardiac pacemaker generator. Manipulation of the existing pacemaker wires entering the left subclavian vein was minimal. Computed tomographic angiography of the neck demonstrated near-complete thrombotic occlusion of the entire length of his left IJ vein. This required hospital admission for observation and treatment with anticoagulation. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: DVT, with thrombotic extension into adjacent vessels anywhere along the course of pacemaker wires, should be considered by the emergency provider in the evaluation of head, neck, or upper extremity symptoms after recent or remote implantation or manipulation of a transvenous cardiac pacemaker, including generator replacement. Failure to identify and treat appropriately could result in significant morbidity and mortality from airway edema, septic thrombophlebitis, superior vena cava syndrome, superior sagittal sinus thrombosis, or pulmonary embolism.

The American Heart Association recommends a "meticulous history" when evaluating patients with an initial episode of syncope. However, little is known about which historical features are most helpful in identifying children with undiagnosed cardiac syncope. ⋯ Our study, which represents the largest published series of pediatric syncope presenting to the ED, confirms that newly diagnosed cardiac causes of syncope are rare. Using a few specific historical features on initial interview can help guide further work-up more precisely.

Reversible cerebral vasoconstriction syndrome (RCVS) is an underappreciated and poorly understood cause of thunderclap headache (TCH). Although self-limited in the majority of patients, incidence is increasing, with presentations overlapping considerably with life-threatening conditions, such as aneurysmal subarachnoid hemorrhage and stroke. In addition, radiographic findings seen in RCVS are also present in primary angiitis of the central nervous system (PACNS). Misdiagnosis of RCVS might subject patients to unnecessary invasive testing and immunosuppressive therapy. Furthermore, the recommended treatment of glucocorticoids used in PACNS can be harmful in RCVS. RCVS is not a benign condition, as patients can have ischemic or hemorrhagic complications leading to persistent neurologic deficits and even death. Current treatments, guided only by expert consensus, have no proven effect on these complications, which argues the need for accurate identification of patients with RCVS and prospective studies to validate treatment and inform prognoses. ⋯ We describe a previously healthy male who presented to the emergency department after 2 episodes of TCH and angiography consistent with RCVS. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: RCVS is a common but underappreciated cause of TCH. The likelihood of misdiagnosing RCVS following the accepted diagnostic algorithm of acute headache in the emergency department is high due to a lack of clinical awareness and common features shared with other headache syndromes. Emergency department physicians must broaden the differential in patients presenting to the emergency department with TCH to include RCVS and be familiar with the accepted treatments and appropriate follow-up.

Review Case Reports
Crowned Dens Syndrome: Report of Three Cases and a Review of the Literature.
Patients with crowned dens syndrome (CDS), which is pseudogout of the atlantoaxial junction induced by "crown-like" calcifications around the dens, present with symptoms of severe neck pain, rigidity, and high fever. CDS patients are often misdiagnosed as having meningitis or polymyalgia rheumatica, leading to potentially unnecessary invasive procedures for diagnosis and treatment. ⋯ We report 3 patients with CDS who had characteristic findings on computed tomography (CT), all of whom quickly recovered with nonsteroidal antiinflammatory drug (NSAID) administration. In addition, we reviewed 72 published cases, including our patients. CDS typically occurs in elderly people (mean age 71.4 years). Common symptoms include neck pain (100%), neck rigidity (98%), and fever (80.4%), and most show elevated inflammatory markers (88.3%) on serum laboratory tests. Neck pain on rotation is a characteristic and helpful symptom in the diagnosis. The most useful modality is CT (97.1%), showing linear calcium deposits around the dens, mostly in the transverse ligament of atlas (TLA). CT number is especially helpful to distinguish a normal TLA (35-110 HU) from a calcified one (202-258 HU) in our cases. The most effective treatment is NSAID administration (85%), which usually leads to marked resolution of symptoms within days or weeks. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Due to acute and severe symptoms, CDS patients often present to an emergency department. To avoid unnecessary invasive procedures for diagnosis and treatment, CDS should be considered in the differential diagnosis of febrile neck pain.
