Selective intestinal decontamination (SID) with norfloxacin has been widely used for the prophylaxis of spontaneous bacterial peritonitis (SBP) because of a high recurrence rate and preventive effect of SID for SBP. However, it does select resistant gut flora and may lead to SBP caused by unusual pathogens such as quinolone-resistant gram-negative bacilli or gram-positive cocci. Enterococcus hirae is known to cause infections mainly in animals, but is rarely encountered in humans. We report the first case of SBP by E. hirae in a cirrhotic patient who have previously received an oral administration of norfloxacin against SBP caused by Klebsiella pneumoniae and presented in septic shock.

Cronkhite-Cadana syndrome is a rare non-familial disease. This syndrome is characterized by multiple hamartomatous polyps on the entire gastrointestinal tract except esophagus, nail dystrophy, alopecia and hyperpigmentation. Taste disturbance, abdominal pain, diarrhea and weight loss are common symptoms of it. The pathogenesis and causes of Cronkhite-Canada syndrome remain unknown until now. Although various treatment strategies including steroid therapy have been tried, their prognosis is poor. We report a 68 years old man who were diagnosed Cronkhite-Canada syndrome with esophageal candidiasis. After using combination of steroids and anti-fungal drugs, both Cronkhite-Canada syndrome and esophageal candidiasis were cured. (Korean
