Introduction: Acute myocardial infarction (AMI) rarely occurs during pregnancy and presents unique challenges in diagnosis and management. Traditionally, pregnancy has not readily been considered a risk factor for AMI in the emergency department despite the potential for adverse impacts on maternal and fetal health. As cardiovascular risk factors and advanced maternal age become more prevalent in society over time, the incidence will continue to increase.

BACKGROUND Non-atherosclerotic causes of ST-segment elevation myocardial infarction (STEMI) are uncommon, and there are few case reports of acute myocardial infarction secondary to coronary artery embolism. CASE REPORT A 66-year-old man presented with shortness of breath and leg swelling. Diagnoses of congestive heart failure and atrial fibrillation were made.

Acute pulmonary embolism remains a common cause of mortality. Early diagnosis and appropriate risk stratification is necessary to individualize treatment strategy. Computed tomography scan of the pulmonary arteries is routinely used to diagnose acute pulmonary embolism and in some cases is useful to assess right ventricular dilation.

Myocardial infarction (MI) due to coronary atherosclerosis in young adults is uncommon; rare causes such as cocaine abuse, arterial dissection, and thromboembolism should be considered. A 21-year-old football player, and otherwise healthy African American man, developed chest pain during exercise while bench-pressing 400 lbs. Acute MI was diagnosed based on physical examination, electrocardiography findings, and elevated cardiac enzymes.

Platinum-based antineoplastic drugs are widely used in the treatment of solid tumors. Carboplatin, a second generation platinum compound, was developed to have less nonhematologic toxicity, in comparison with cisplatin. We report on a 34-year-old woman with breast cancer who developed gross hematuria after initiation of carboplatin-based chemotherapy.

Study Design: Simulated translation of the C5 vertebra was performed in 20 embalmed cadaveric cervical spines, and cross-sectional areas of the C4-C5 and C5-C6 intervertebral foramina were measured and compared before and after translation of the C5 vertebra.

Objective: To determine the relationship of cross-sectional intervertebral foraminal areas to the degrees of vertebral translation.

Summary Of Background Data: The common feature of clinical instability and adjacent diseases of the cervical spine is malalignment of the cervical spine (i.

We found an extremely large perforating branch of peroneal artery in an 89-year-old female cadaver's left ankle. The anterior tibial artery could not reach to supply the ankle and dorsum of the foot. The perforating branch of peroneal artery continued as the dorsalis pedis after giving off an anterior lateral malleolar artery branch.

Background Context: Transarticular C1-2 screws are widely used in posterior cervical spine instrumentation. Injury to the vertebral artery during insertion of transarticular Cl-2 screw remains a serious complication. Use of a computer-assisted surgery system decreases this complication considerably.
