EMPYEMA
10. What is an empyema, and what causes it?
Show answer
An empyema is a purulent (infected) effusion. Fluid or blood in the pleural space can be directly innoculated (with bugs) during surgery or trauma (33%) or by contamination from contiguous sites (50%) such as bronchopulmonary infection (most common). Most empyemas are parapneumonic, and the most commonly involved organisms are Staphylococcus aureus, enteric gram-negative bacilli, and anaerobes. Many times, infections are polymicrobial. Often there is no growth of an empyema culture because of effective antibiotic therapy or inadequate culture techniques, particularly with anaerobes.

30. What is celiac compression syndrome (Dunbar’s syndrome)?
Show answer
Celiac compression is a rare and controversial disorder most commonly described in women (female-to-male ratio = 4:1) between the ages of 20 and 50 years. Patients appear to suffer from chronic mesenteric ischemia without angiographic evidence of atherosclerotic disease. The mechanical compression is believed to be caused by the left crus of the diaphragm (i.e., marginal arcuate ligament), and diagnosis occasionally is confirmed by demonstrating transient celiac compression during expiration. The associated pain is the result of a complicated and still heavily debated redirection of flow (foregut steal) away from the SMA. Effective treatment has required not only release of the compression but also bypass to improve the likelihood of pain resolution.
