Foreign Bodies in the Skin: Evaluation and Management.

Foreign bodies may be introduced into the skin through lacerations and soft tissue wounds. Long-term complications of retained foreign bodies include chronic pain and neurovascular impairment. Wound exploration and initial imaging with radiography or ultrasonography should be considered before foreign body removal. Risks and benefits of removal should be discussed with the patient. Although some foreign bodies may be left in place, removal should be considered if the risk of complications is high. A cooperative patient and adequate wound visualization are important for successful foreign body removal. Adequate analgesia and judicious use of anxiolytics and sedation may be helpful. Wound irrigation with normal saline or tap water is recommended after foreign body removal. Antiseptic solutions for wound irrigation may impair healing and should be avoided. Although there is no consensus on the use of antibiotic prophylaxis, several indications exist. The patient's tetanus immunization history should be reviewed, and vaccine should be administered if indicated.

Pleuritic Chest Pain: Sorting Through the Differential Diagnosis.

Pleuritic chest pain is characterized by sudden and intense sharp, stabbing, or burning pain in the chest when inhaling and exhaling. Pulmonary embolism is the most common serious cause, found in 5% to 21% of patients who present to an emergency department with pleuritic chest pain. A validated clinical decision rule for pulmonary embolism should be employed to guide the use of additional tests such as d-dimer assays, ventilation-perfusion scans, or computed tomography angiography. Myocardial infarction, pericarditis, aortic dissection, pneumonia, and pneumothorax are other serious causes that should be ruled out using history and physical examination, electrocardiography, troponin assays, and chest radiography before another diagnosis is made. Validated clinical decision rules are available to help exclude coronary artery disease. Viruses are common causative agents of pleuritic chest pain. Coxsackieviruses, respiratory syncytial virus, influenza, parainfluenza, mumps, adenovirus, cytomegalovirus, and Epstein-Barr virus are likely pathogens. Treatment is guided by the underlying diagnosis. Nonsteroidal anti-inflammatory drugs are appropriate for pain management in those with virally triggered or nonspecific pleuritic chest pain. In patients with persistent symptoms, persons who smoke, and those older than 50 years with pneumonia, it is important to document radiographic resolution with repeat chest radiography six weeks after initial treatment.
