BACKGROUND: This is a retrospective, descriptive study, evaluating the observed agreement between 1996 & 2002 Centers for Disease Control and Prevention (CDC) definitions of nosocomial pneumonia (NP) for medical intensive care unit (MICU) and surgical intensive care unit (SICU) patients. METHODS: A total of 476 adult patients who were over 15 years of age and had been admitted to the MICU & SICU of a university hospital between August 1, 2005 and August 1, 2007 were enrolled. Data were collected from electronic medical records according to the 1996 & 2002 CDC definitions of NP. RESULTS: According to the 1996 CDC definitions of NP, there were a total of 116 NP cases and incidence rate was 11.6 per 1,000 patient-days; when analyzed with the 2002 CDC definitions of NP, 75 cases met the criteria and the incidence rate was 7.5 per 1,000 patient-days. Kappa value measuring agreement between the two definitions was 0.67 (95% confidence interval 0.601-0.706). When 1996 CDC definitions were compared with 2002 CDC definitions, sensitivity, specificity, positive predictive value, and negative predictive value were 93.3, 88.5, 60.3, and 98.6%, respectively. CONCLUSION: Even though the aforementioned NP criteria had been applied to the same study population, the number of patients that met the definitions changed depending on which criteria had been used. Therefore, it is necessary to consider the differences when making a comparison.

An unusual case of intraspinal peripheral neuroepithelioma arising from the cauda equina is reported. The patient, a 21-year old female, suffered from low back pain with radiation to the posterior aspect of both legs. Myelographic, computed tomographic scan and magnetic resonance imaging studies of lumbosacral spine showed the intradural extramedullary mass lesion on the L3-S1 level which was excised surgically, but recurred rapidly. It could be diagnosed by the histopathologic findings. The postoperative radiotherapy and chemotherapy were administered. We report this rare case with review of the literatures.

The double pylorus-is a fistulous communication between the gastric antrum and duodenal bulb, usually extending from the lesser curvature of the stomach to the superior aspect of the duodenal bulb, and seperated by septum or bridge of normal mucosa. Although its incidence is rare, reports concerning double pylorus are increasing with the recent development of upper gastrointestinal endoscopy and more awareness of this abnormality. We recently experienced two cases of double pylorus; an aquired one in 72-year old male who had an another opening with healing ulcer at the superior aspect of the original pyloric channel, central erosion with clubbing and fusion of mucosal folds at the greater curvature of the lower body and a 3 x 4 cm sized ulcer at the lesser curvature of the lower body, and the other congenital one in 53-year old male who had an another opening at the superior aspect of the original pyloric channel with histologically intact muscularis mucosa in the pyloric septum with no evidence of chronic peptic ulcer scarring. We report here two cases of double pylorus, one-acquired, and the other-congenital, with a review of the literature.

We report a case of neuroblastoma with multiple skin metastases as a chief complaint in a 2-month-old girl. the skin lesions were rnultiple, pea-sized, bluish, nontender, moable subcutaneous nodules on abdomen, back and scalp. Histopathology showed small round or poly gonal tumor cells which have deeply stained, basophilic, hyperchromatic nuclei with some mitoses. Th.se tumor cells showed clumping tendency which is one of early menifestations of rosette formation. Immunohistochemically positive reaction was demonstrated by anti-NSE(neuron specific enolase) antilody but negative reaction by anti-NFP (neurofilament proteiin ) antibody. She has been succesfully treated with combined chemotherapy for 10 months without relapse.

The gastrointestinal lymphoma is a well known entity for bleeding or perforation during treatment, but spontaneous perforation is not common. We report the CT findings of an unusual case of small bowel lymphoma which presented with massive pneumoperitoneum following spontaneous perforation.
