Tularemia pneumonia.

Tularemia pneumonia may complicate the various clinical presentations of tularemia, or present as an uncommon zoonosis. Approximately 200 cases of tularemia are reported in the United States per year, and 10% to 20% present with pneumonia either as a primary event or as a complication of ulceroglandular or typhoidal tularemia. Tularemia pneumonia also occurs with the other tularemic forms, glandular, oculoglandular, and oropharyngeal tularemia as a result of secondary bacteremic spread to the lungs.

Postpericardiotomy syndrome.

Fever after a cardiac operation is commonly caused by myocardial infarction, postpericardiotomy syndrome, post-myocardial infarction syndrome (Dressler's syndrome), or postperfusion syndrome resulting from cytomegalovirus infection. Postpericardiotomy syndrome and post-myocardial infarction syndrome are autoimmune disorders characterized by eosinophilia, pleuritic chest pain, and pleural effusions. In contrast, the diagnosis of postperfusion syndrome caused by cytomegalovirus is suggested if the patient has a mild sore throat, no pleural component or chest pain, no eosinophilia, and atypical lymphocytosis.

Escherichia coli sternal osteomyelitis after open heart surgery.

Deep-seated infections after open-heart surgical procedures, fortunately, are uncommon with appropriate prophylactic antibiotics and careful aseptic technique. When serious infection, such as sternal osteomyelitis, does occur, the effects are devastating and usually require one or more debridement procedures. The organisms usually implanted in postoperative sternal infections are primarily Staphylococcus aureus and aquatically based gram-negative bacilli.

Regulation of electrolyte transport with IL-1beta in rabbit distal colon.

Interletrkin-1beta levels are elevated in inflammatory bowel disease. In this study the mechanism by which interleukin-1beta affects electrolyte transport in the rabbit distal colon, was investigated. Interleukin-1beta caused a delayed increase in short-circuit current (I(sc)) which was attributed to protein synthesis since the effect was inhibited by cycloheximide.

Klebsiella pneumoniae splenic abscess.

Splenic abscesses may be solitary or multiple and are unusual infections. Signs and symptoms are variable and do not always include left upper quadrant pain or tenderness, as the Case Report illustrate. Abscesses of the spleen may occur as a result of endocarditis or from hematogenous seeding from a distant focus of infection.
