RESUMEN
For the first time, we report Klebsiella pneumoniae as an enteroinvasive food-borne pathogen transmitted from a hamburger. A 28-year-old previously healthy African-American male ingested a portion of a hamburger from a fast food chain. Symptoms of gastroenteritis rapidly deteriorated to multiorgan failure. Blood and hamburger cultures grew Escherichia coli and Klebsiella pneumoniae. Since Klebsiella had not previously been reported as enteroinvasive, the isolates were compared. Full biochemical profiles, antimicrobial sensitivity, plasmid profile, and toxin assay by DNA hybridization probe were completely concordant. The patient survived the episode of food-borne sepsis. Deliberate or inadvertent employee contamination of food products with feces may be a potential source of life-threatening food-borne illness.

Pylephlebitis or septic thrombophlebitis of the portal vein, a precursor of hepatic abscesses, is an extremely rare and frequently fatal complication of diverticulitis. The following report describes a patient presenting with pylephlebitis and complicated diverticulitis. Diagnosis was confirmed by computed tomography. The patient had a favorable outcome with medical and surgical therapy, prompting us to evaluate historical treatment of pylephlebitis.

A 47 year old woman with systemic lupus erythematosus was found to have asymptomatic pulmonary nodules. Histologically they represented benign reactive lymphoreticular hyperplasia compatible with the diagnosis of pseudolymphoma. Immunofluorescence and electron microscopy demonstrated immunoreactants and electron-dense deposits in the alveolar and vascular walls, suggesting that an immune complex mechanism may be involved in this case.
