A pathological study was done to elucidate sequential changes of the lungs in various time intervals following experimental paragonimiasis in 15 dogs and 15 cats. The dogs and cats were fed with 30-50 metacercariae of Paragonimus westermani, and were sacrificed at 15, 20, 30, 45, 60, 90 and 120 days after infection respecively. Autopsies were performed immediately after death. Gross and microscopic examination of the lungs showed following findings: There were no qualitative difference in pathological findings between dogs and cats. Pathological findings were first noticed at 20 days of infection in thoracic cavity, which consisted of fibrinous plueritis along with superficial hemorrhage. Although no worm was found in the lung parenchyma at this period, juveniles were seen in pleural cavity together with turbid effusion. Paragonimus juveniles were first recognized inside the lung parenchyma by 30 days of infection. This was the period when the lungs showed multiple areas of hemorrhage and probably active penetration by smaller worms. Hemorrhagic bronchopneumonia was quite pronounced from this stage through 45 days of infection. Paragonimus worm cyst was essentially composed of fibrous scar and heavy inflammatory cellular infiltrate. The lining epithelial cells were first became noticed by 2 months of infection. And these epithelial cells were thought to be probably transformed alveolar lining cells rather than bronchiolar epithelial cells. As the infection progress, the cyst wall became more stabilized and often showed squamous metaplasia. Fibrinous pleuritis with pleural effusion was very prominent finding in early periods of infection. Bronchiolitis and focal vascular sclerosis were often seen in experimental paragonimiasis.

BACKGROUND: Carbapenem-resistant Enterobacteriaceae (CRE) with acquired metallo β-lactamase (MBL) resistance have been increasingly reported worldwide and associated with significant mortality and morbidity. Here, an outbreak of genetically related strains of Klebsiella pneumoniae producing the imipenemase (IMP)-1 MBL in a medical intensive care unit (MICU) in Korea is reported. METHODS: Since isolating carbapenem-resistant K. pneumoniae (CRKP) at the MICU of the hospital on August 10, 2011, surveillance cultures for CRE in 31 hospitalized patients were performed from August to September 2011. Carbapenem resistance was determined based on the disk diffusion method outlined in the Clinical and Laboratory Standards Institute guidelines. Polymerase chain reaction (PCR) was performed for genes coding for β-lactamase. Associations among isolates were assessed via pulsed-field gel electrophoresis (PFGE). In addition, a surveillance study of environmental cultures and health-care workers (HCWs) was conducted in the MICU during the same time frame. RESULTS: During the study period, non-duplicated CRKP specimens were discovered in four patients in the MICU, suggestive of an outbreak. On August 10, 2011, CRKP was isolated from the sputum of a 79-year-old male patient who was admitted to the MICU. A surveillance study to detect additional CRE carriers by rectal swab revealed an additional three CRKP isolates. PCR and sequencing of the four isolates identified the presence of the IMP-1 gene. In addition, PFGE showed that the four isolated strains were genetically related. CRE was not identified in specimens taken from the hands of HCWs or other environmental sources during surveillance following the outbreak. Transmission of the carbapenemase-producing Enterobacteriaceae strain was controlled by isolation of the patients and strict contact precautions. CONCLUSIONS: This study shows that rapid and systemic detection of CRE and strict infection controls are important steps in preventing nosocomial transmission.

Retropsoas space below the level of kidney has been suggested as a portion of inferior extensions of perirenal and anterior and posterior pararenal spaces. With this being true, the space may play an important role in disease extension. A study was performed to verify the existence of retropsoas peritoneal recess by means of identifying the extension of bowel loops into this space. Abdominal CT scans of 146 cases evaluated retrospectively revealed extension of 5 small bowel and 7 large bowel loops (6 descending and 1 ascending colons)(n=12/8.2%) into the retropsoas space verifying its existence. Since pathologic collection within the retropsoas space might be falsely inter preted as a retroperitoneal pathology and percutaneous uroradiologic intervention could result in intraperitoneal injury or contamination without the knowledge on the existence of this space, observation of this space is essential in CT scans.

BACKGROUND: Antimicrobial resistance of Streptococcus pneumoniae presents a challenge to the clinicians in developing countries, particularly against the acute respiratory tract infections, including pneumonia. The present study was to evaluate the carriage rate and the antimicrobial resistance of S. pneumoniae isolated from children at a day-care center. METHODS: Oropharyngeal swabs were done every month for one year in 64 children at a day-care center in Seoul, Korea. Minimum inhibitory concentrations (MICs) of 9 antimicrobial agents (penicillin, ceftriaxone, cefuroxime, erythromycin, chloramphenicol, tetracycline, vancomycin, ciprofloxacin, cefpirome) were determined by agar-dilution method. RESULTS: The ages of the children ranged from 13 to 60 months (mean: 31 months). The overall carriage- rate of pneumococci was 26%, which was highest in December (46%) and lowest in July (3%). A total number of 105 strains of S. pneumoniae were isolated from 404 throat swabs and 68 strains among these were available for MIC tests. Only 8 (12%) strains were susceptible to penicillin, while 50 (73%) were intermediate and 10 (15%) were resistant. The isolates also exhibited high rates of resistance to other beta- lactams (53% and 21% were resistant to cefuroxime and ceftriaxone, respectively). The resistance rates to the other antimicrobial agents were also remarkable; 90% and 88% were resistant to erythromycin and tetracycline, respectively. However, 75% of isolates were susceptible to chloramphenicol and 100% were susceptible to vancomycin. CONCLUSION: There was a high rate of pharyngeal carriage of penicillin-resistant S. pneumoniae among children attending day-care center. Surveillance of pharyngeal cultures may provide useful information the treatment guideline of pneumococcal infections.

BACKGROUND: Brief episode of coronary artery occlusion (i.e., ischemic preconditioning) makes the heart more resistant to injury from a subsequent ischemic insult. Although a great deal of effort has been made in studying ischemic preconditioning, the underlying mechanism of ischemic preconditioning and its effect on hypothermic insult has not been elucidated. This study was performed to see whether ischemic preconditioning protects against the depression of cardiac contractility induced by hypothermic cardioplegic arrest/reperfusion. And recently, adenosine was known to have some correlation with the mechanism of preconditioning. If so, does this effect remain after the blockade of adenosine receptor by 8-phenyl theophylline? METHOD: Twenty-four Sprague-Dawley rat weighed 250-350g were used and divided into three groups. Rat hearts were removed rapidly, and each isolated heart paced with a rate of 180/min was perused by modified Krebs-Hensleit buffer(KHB) solution on a Langendorff apparatus far an hour. After obtaining baseline data including left ventricular pressure(LVP), dp/dt, and coronary flow, cardiac arrest was induced by perfusion of 0degrees C crystalloid cardioplegic(St Thomas) solution. After that, all hearts were stored in the same St Thomas solution at salute temperature far 2 hours. In group I (control group), the hear was reperfused by KHB solution. In group II(preconditioning group), the heart was subjected to two 2-minute episode of global ischemia followed by 5 minute reperfusion with KHB solution(preconditioning) before cardiac arrest. In group III(phenyl theophylline group), the heart was subjected to preconditioning procedure and 8-phenyl theophylline at 10muM in concentration was added to KHB solution at time of reperfusion. Observing parameter was obtained in each group at 10, 20, 40 and 60 minutes after starting reperfusion and compared statistically by use of one way ANOVA test(STASTICA, release 4.5). P-value less than 0.05 was considered significant. RESULTS: Although depressed LVP, dp/dt, and Coronary flow were seen in all groups during the reperfusion period, the preconditioned group showed more effective recovery of LVP than that of the control group, especially at 10, 20 and 40 minutes(p<.05). We failed to demonstrate the difference between the phenyl theophylline group and the control group(p=NS). CONCLUSION: These results suggest that ischemic preconditioning has protective effect on recovery state of hypothermic cardioplegic arrest/reperfusion. Its protective effect was limited during early reperfusion stage and was blocked by adenosine blocker.
