Acute phlegmonous gastritis is an uncommon disease, often fatal condition characterized by suppurative bacterial infection of the gastric wall. It has a high mortality rate mainly because the diagnosis is usually made late. Until recently, gastrectomy in combination with antibiotics was recommended. We had experienced a case of 66-year-old man presented with epigastric pain, nausea, vomiting, and hematemesis, followed by aspiration pneumonia. At upper gastrointestinal endoscopy, the gastric lumen was narrow, and the mucosa was severely inflamed, which was erythematous, swelled, and showed necrotic areas covered with purulent exudate. Klebsiella oxytoca and Acinetobacter lwoffii were isolated in the gastric tissue culture. Contrast-enhanced computerized tomography scan of abdomen demonstrated diffuse gastric wall thickening and an intramural abscess in the gastric antral wall. Although delayed gastric emptying by gastroparesis prolonged the in-hospital period, the only medical treatment with antibiotics alone successfully cured the patient without gastrectomy.

OBJECTIVETo investigate the antibiotics-resistance type and molecular epidemiology of Streptococcus pneumoniae isolated from children in Hangzhou.

METHODSThe sensitivities of 323 strains of Streptococcus pneumoniae to 9 antibiotics were determined in vitro by Kirby-Bauer diffuse methods, and MICs of penicillin and cefotaxime were determined by E-test methods.

RESULTSAmong all 323 strains isolated from children during the period from August 2001 to July 2002, 136 strains (42.1%) were sensitive to penicillin, while 57 strains (17.7%) were penicillin-resistant. Penicillin MICs ranged from 0.012 microg/ml to 4.0 microg/ml. All the strains were sensitive to cefotaxime and its MICs ranged from 0.012 microg/ml to 4.0 microg/ml. The most resistant antibiotic was erythromycin and it's resistant-rate was as high as 90.7%, followed by tetracycline (87.6%), trimethoprim-sulfamethoxazole (48.6%) and chloromycetin (14.9%). Totally 197 strains (61.0%) were multi-drug-resistant pneumococci and most of them were resistant to trimethoprim-sulfamethoxazole, erythromycin and tetracycline at the same time. Two strains (0.6%) were resistant to rifampin and none was resistant to vancomycin and ofloxacin. BOX PCR typing was carried out and no overwhelming fingerprinting pattern was found among penicillin resistant Streptococcus pneumoniae strains which were isolated from patients, while the banding patterns were always similar or identical among the strains isolated from the same specimen or from the same patient at different time, respectively.

CONCLUSIONThe antibiotics-resistant rate of pneumococci was high in Hangzhou, but the third-generation cephalosporins were still the best antibiotics against Streptococcus pneumoniae. One child could be infected or colonized by more than one pneumococci clone at the same or different time.

Hepatitis A virus (HAV) infections occur predominantly in children, and are usually self-limiting. However, 75-95% of the infections in adults are symptomatic (mostly with jaundice), with the illness symptoms usually persisting for a few weeks. Atypical manifestations include relapsing hepatitis, prolonged cholestasis, and complications involving renal injury. Drug rash with eosinophilia and systemic symptoms (DRESS) syndrome is a severe, drug-induced hypersensitivity reaction characterized by skin rash, fever, lymph-node enlargement, and internal organ involvement. We describe a 22-year-old male who presented with acute kidney injury and was diagnosed with prolonged cholestatic hepatitis A. The patient also developed DRESS syndrome due to antibiotic and/or antiviral treatment. To our knowledge, this is the first report of histopathologically confirmed DRESS syndrome due to antibiotic and/or antiviral treatment following HAV infection with cholestatic features and renal injury.

Pneumatosis cystoides intestinalis (PCI), characterized by presence of intramural gas cyst in the intestinal wall is associated with various medical condition. Polymyosistis, however, is rarely associated with PCI. Few cases are reported in the world, and none has not been reported previously in Korea. A 67-year-old woman with polymyositis developed mild abdominal pain and abdominal distension during treatment with steroid and azathioprine. Radiographic findings including CT scan showed intraperitoneal free gas and intramural air, compatible with PCI. The patient's symptom and clinical findings improved after the treatment with antibiotics and high-dose oxygen therapy.

BACKGROUND/AIMS: Nitric oxide (NO) is a molecule involved in vascular dilatation and pathogen suppression. It also has immunologic and regulatory functions. Liver cirrhosis is characterized by an increased risk for bacterial infections, including spontaneous bacterial peritonitis (SBP). The role of NO in SBP which develops in cirrhosis has not been clearly established. The aim of this study was to investigate the role of NO in the pathogenesis of SBP and its clinical usefulness for prediction of disease prognosis. METHODS: This study was designed to investigate the changes of ascites NO in the course of treatment. Nitric oxide metabolite (nitrites+nitrates [NOx]) was measured by chemiluminescence in 84 ascites samples obtained from 84 cirrhotic patients. Among them, the 38 patients with SBP were treated with cefotaxime 2.0 g, q 12hr for 7 days. In 24 of SBP patients, ascites was obtained consecutively before treatment (day 0), during treatment (day 2), and after treatment (day 7). RESULTS: Ascites NO levels in the patients with SBP (n=38; 82.3 +/- 14.4 micro M) were not different from those in patients with sterile ascites (n=46; 54.6 +/- 13.0 micro M). There was no significant change of NO levels in sequential ascites samples during antibiotic treatment. Ascites NO level before treatment was significantly higher in SBP patients who responded to antibiotics (n=26; 101.86 micro M/L) than that in SBP patients who did not respond to antibiotics (n=12; 40.03 micro M/L, P=0.044). A significant direct correlation was found between ascites and serum NO levels before treatment (Pearson correlation, r2=0.86, P=0.001). Among the SBP patients, treatment response rate to antibiotics were significantly higher in those patients with pretreatment NO level>or=80 micro M/L in multivariate analysis. CONCLUSIONS: Ascites NO level was not different between ascites from SBP patients and ascites from cirrhotic patients with sterile ascites. There were no changes of ascites NO in SBP patients during treatment. Therefore ascites NO was not useful to predict the progress of SBP. Ascites NO levels reflect serum NO levels, and the patients with higher NO level may have better response to antibiotics.

Megalocytic interstitial nephritis is a rare form of kidney disease caused by chronic inflammation. We report a case of megalocytic interstitial nephritis occurring in a 45-yrold woman who presented with oliguric acute kidney injury and acute pyelonephritis accompanied by Escherichia coli bacteremia. Her renal function was not recovered despite adequate duration of susceptible antibiotic treatment, accompanied by negative conversion of bacteremia and bacteriuria. Kidney biopsy revealed an infiltration of numerous histiocytes without Michaelis-Gutmann bodies. The patient's renal function was markedly improved after short-term treatment with high-dose steroid.
