A point-of-care ultrasound approach to fascia iliaca nerve block in a patient with a hip fracture.

According to the Centers for Disease Control and Prevention, hip and femoral neck fractures are common fractures seen in older adults. Lower extremity nerve blocks are a tool available for pain control in these patients. One type of block that can be used in this type of fracture is the fascia iliaca compartment block.

Atraumatic Bi-femoral Axillary Bypass Graft Non-anastomotic Disruption With Pseudoaneurysm Formation Detected by Doppler Ultrasound.

Bi-femoral axillary bypass graft placement is a well-known and typically safe procedure. It is generally indicated for patients with advanced peripheral vascular disease, aortoiliac occlusive disease, or infectious artery disease. In rare cases, the graft can be fractured or dislodged after placement, though most often, this occurs almost exclusively at the anastomosis site, secondary to blunt trauma.

Adlayer influence on Dirac-type surface state at W(110).

In a combined experimental and theoretical study, we investigated how Fe and Co adlayers on W(110) affect the Dirac-type surface state (DSS). Angle-resolved photoelectron spectroscopy data show an increase in binding energy of 75 meV and 107 meV for Fe and Co, respectively. In order to identify the origin of the energy shift we performed first-principles calculations of the surface electronic structure.

Altered Mental Status and Cyanosis in a Pediatric Patient with Methemoglobinemia.

Methemoglobinemia results from increased amounts of oxidized hemoglobin in the blood with an ensuing change in oxygen dissociation curve and lack of oxygen delivery to tissue. A previously well, male toddler was brought to the Pediatric Emergency Department (PED) by Emergency Medical Services (EMS) with abrupt onset of altered mental status and cyanosis after a suspected ingestion of "Rush" nail polish remover. He was quickly diagnosed with methemoglobinemia by both clinical presentation and chocolate-colored blood appearance.
