Clinical Characteristics and Prognosis of Acinetobacter Nosocomial Pneumonia between MDR and non-MDR / 결핵및호흡기질환

BACKGROUND: Acinetobacter baumannii has emerged as an important nosocomial pathogen worldwide. The incidence of these infections has recently begun to increase. The mortality rate associated with these infections is high (bacteremia; 52% , pneumonia: 23%~73%) and multidrug resistance has been reported. For the effective control of multidrug- resistant Acinetobacter baumannii(MDR-AB), the impact of these organisms in clinical practice should be determined. This study compared the clinical characteristics, mortality and morbidity of Acinetobacter nosocomial pneumonia between MDR strain and non-MDR strain. METHODS: From Jan. 1, 2002 to Nov. 1. 2004, 47 adult patients with Acinetobacter nosocomial pneumonia in Chuncheon Sacred Heart Hospital were recruited and analyzed retrospectively. MDR-AB was defined as showing in vitro resistance to all commercially available antibiotics against A. baumannii. RESULTS: There were 47 patients with Acinetobacter nosocomial pneumonia. MDR-AB and non MDR-AB was the cause of the pneumonia in 17 and 30 patients, respectively. Mean age of the former was 69+/-11 years old and the latter was 70+/-13 years old. The mean APCHE II score, ICU days and mortality were not different between the two groups(16.1+/-5.4 vs. 14.9+/-4.8, P=0.43, 25.1+/-13.6 vs. 39.1+/-31.0, P=0.2, 58.8% vs. 40%, P=0.21). CONCLUSION: There are no significant differences in mortality and morbidity between MDR and non-MDR Acinetobacter baumannii. The mortality of the two groups is surprisingly high, therefore proper infection control practices are essential.

Two Cases of Acute Hepatitis E in Patients with Hyperthyroidism / 대한소화기학회지

Acute hepatitis E occur commonly as outbreaks in endemic areas, but can occur sporadically in other part of the world. Acute hepatitis E has been reported rarely in Korea. A case of concurrent acute hepatitis E virus (HEV) infection and hyperthyroidism was reported in an inactive hepatitis B surface antigen carrier. We experienced two cases of concomitant acute HEV infection in patients with hyperthyroidism. The first case had acute HEV infection with subclinial hyperthyroidism while taking propylthiouracil. The second case suffered from acute HEV infection in a patient with Graves' disease intractable to propylthiouracil. Herein, we suggest the possible association between HEV infection and hyperthyroidism.

A Case of Liver Abscess Caused by Toothpick Penetrating Gastric Wall / 대한소화기내시경학회지

The ingestion of foreign bodies into the gastrointestinal tract is common, and most are passed out spontaneously without causing any problems. However, a perforation can cause a variety of complications involving considerable morbidity and mortality. Moreover, clinical presentation of a perforation can vary and patients are often unaware of the episode. Hence, a pre-operative diagnosis is difficult under these circumstances. We report an unusual case of a liver abscess that developed secondary to a toothpick that had penetrated the gastric wall and migrated to the liver. The liver abscess was treated successfully with internal drainage by inserting an endoscopic pigtail catheter through the hepato-gastric fistula. The toothpick was removed using an endoscopic snare.
