Hyperplastic gastric polyps (HPPs) are the most common type of gastric polyps. They are assumed to be caused by chronic inflammation and regenerative proliferation, although this has not been clearly investigated yet. Many studies suggested the development of fundic gland polyps and carcinoid during long-term proton pump inhibitor (PPI) therapy, but the relationship between PPIs and HPPs is still unclear. We encountered a patient who showed aggravation of HPPs after long-term use of PPIs. A 58-year-old male patient with liver cirrhosis visited our hospital because of hematemesis. We started PPI medication after confirming esophageal variceal bleeding and duodenal ulcer with blood clot in its base via emergency endoscopy. He took PPIs for three years because of an intractable duodenal ulcer. There was a marked increase in the size of the pre-existing polyps and in the development of new polyps. We presumed that the PPIs caused the aggravation of the HPPs, so we stopped their administration. After five months, the HPPs shrank and the polyps were partially degraded. More prospective studies are needed to investigate the relationship between HPPs and PPIs.

A choledochocele is an expanded sac of the duodenal side of the distal common bile duct (CBD), and is categorized as a type III choledochal cyst. Unlike other choledochal cysts, it can be easily overlooked because of its very low prevalence, non-specific clinical symptoms, and lack of distinctive radiological findings. However, a patient having a repeated pancreaticobiliary disorder with an unknown origin, frequent abdominal pain after cholecystectomy, or repeated non-specific gastrointestinal symptoms can be suspected as having a choledochocele, and a more accurate diagnosis can be achieved via endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasound. Because it rarely becomes malignant, a choledochocele can be treated via endoscopic sphincterotomy (EST) and surgical treatment. The authors were able to diagnose choledochocele accompanied by a stone in a patient admitted to the authors' hospital due to cholangitis and pancreatitis. The patient's condition was suspected to have been caused by a distal CBD stone detected via multiple detector computed tomography and ERCP, and was successfully treated via EST.

PURPOSE: Survival outcome of locally advanced pancreatic cancer has been poor and little is known about prognostic factors of the disease, especially in locally advanced cases treated with concurrent chemoradiation. This study was to analyze overall survival and prognostic factors of patients treated with concurrent chemoradiotherapy (CCRT) in locally advanced pancreatic cancer. MATERIALS AND METHODS: Medical records of 34 patients diagnosed with unresectable pancreatic cancer and treated with definitive CCRT, from December 2003 to December 2012, were reviewed. Median prescribed radiation dose was 50.4 Gy (range, 41.4 to 55.8 Gy), once daily, five times per week, 1.8 to 3 Gy per fraction. RESULTS: With a mean follow-up of 10 months (range, 0 to 49 months), median overall survival was 9 months. The 1- and 2-year survival rates were 40% and 10%, respectively. Median and mean time to progression were 5 and 7 months, respectively. Prognostic parameters related to overall survival were post-CCRT CA19-9 (p = 0.02), the Eastern Cooperative Oncology Group (ECOG) status (p < 0.01), and radiation dose (p = 0.04) according to univariate analysis. In multivariate analysis, post-CCRT CA19-9 value below 180 U/mL and ECOG status 0 or 1 were statistically significant independent prognostic factors associated with improved overall survival (p < 0.01 and p = 0.02, respectively). CONCLUSION: Overall treatment results in locally advanced pancreatic cancer are relatively poor and few improvements have been accomplished in the past decades. Post-treatment CA19-9 below 180 U/mL and ECOG performance status 0 and 1 were significantly associated with an improved overall survival.

Most ingested foreign bodies spontaneously pass through the upper and lower intestinal tract. The impaction of an ingested foreign body in the colon is rare. Foreign bodies swallowed inadvertently often cause serious complications, such as perforation, obstruction, abscess formation, enterocolic fistula, or hemorrhage. Physicians should proceed with routine medical care while considering the possibility of the ingestion of a foreign body In cases where abdominal pain of an unknown origin is observed, particularly in elderly patients who wear dentures, alcoholics, mentally disturbed, or rapid eating, and presenting with altered bowel habits. We report a case of a colonoscopically-removed wooden toothpick that impacted the sigmoid colon and was complicated by the formation of a local abscess with a review of the literature.

Melanosis ilei is a condition that's characterized by gross greyish-black or brownish-black pigmentation of the mucosa of the terminal ileum. There were several substances that produce gastrointestinal tract pigmentation such as lipofuscin, iron sulphide (FeS), Hemosiderin and exogenous material such as silicates and titanium. We report here on a case of a 58-year-old female who ingested charcoal for a long time, and she was diagnosed with melanosis ilei by colonoscopy. Her condition improved after she stopped ingesting the charcoal.

Hypereosinophilic syndrome, the disease with continuous over production of eosinophil from bone marrow without any identifiable underlying disorder, causes various symptoms or signs by infiltrating organs. As many as 28,780/mm3 eosinophils in peripheral blood, the eosinophilic hyperplasia in bone marrow and features of hepatic involvement -revealed elevated serum AST, ALT and ultrasonogram of abdomen showed the multiple nodules scattered throughout the liver, we have reached to make a diagnosis of the rare hyper eosinophilic syndrome carrying the eosinophil-rich exudate in pleural effusion. The patient showed improvement of clinical symptoms with oral administration of predinisolone, and we report this case with literature consideration.

OBJECTIVE: The zero-profile implant (Zero-P) is accepted for use in anterior cervical fusion for the treatment of degenerative cervical disease. However, evidence pertaining to its efficiency and safety in traumatic cervical injury is largely insufficient. This study aimed to compare the overall outcomes of patients who underwent Zero-P for traumatic cervical disc injury.METHODS: Data from a total of 53 consecutive patients who underwent surgery for traumatic or degenerative cervical disc disease using the Zero-P were reviewed. Seventeen patients (group A) had traumatic cervical disc injury and the remaining 36 (group B) had degenerative cervical disc herniation. The fusion and subsidence rates and Cobb angle were measured retrospectively from plain radiographs. The patients’ clinical outcomes were evaluated using the Japanese Orthopedic Association (JOA) score and Odom’s criteria.RESULTS: The C2–7 Cobb and operative segmental angles increased by 3.45±7.61 and 2.94±4.59 in group A; and 2.46±7.31 and 2.88±5.49 in group B over 12 postoperative months, respectively. The subsidence and fusion rate was 35.0% and 95.0% in group A; and 36.6% and 95.1% in group B, respectively. None of the parameters differed significantly between groups. The clinical outcomes were similar in both groups in terms of increasing the JOA score and producing a grade higher than “good” using Odom’s criteria.CONCLUSION: The application of Zero-P in patients with traumatic cervical disc injury was found to be acceptable when compared with the clinical and radiological outcomes of degenerative cervical spondylosis.

BACKGROUND: Dobutamine and amrinone, phosphodiesterase-III inhibitor, are known to have both inotropic and vasodilatory properties. We evaluated the effects of both drugs on systemic and pulmonary hemodynamics in patients with pulmonary hypertension (PH). METHODS: With Institutional Review Board approval, 45 patients whose mean pulmonary arterial pressure was greater than 30 mmHg were studied. After sternotomy under the steady state of anesthesia and controlled ventilation (30 mmHg < PaCO2 < 40 mmHg), patients recieved one of following drugs for 30minutes (min); dobutamine 5.0ug/kg/min (Group I), low dose amrinone (loading dose 1.0 mg/kg, followed by infusion 7.5 g/kg/min, Group II) or high dose amrinone (loading dose 2.0 mg/kg, followed by infusion 10 g/kg/min, Group III). Hemodynamic variables were measured at 10 min and 30 min after start of infusion. RESULTS: Dobutamine didn't decrease pulmonary arterial pressure (PAP) and cause no hemodynamic change while low and high dose amrinone reduced PAP and especcially decrease of PAP in low dose amrinone group was statistically significnat. High dose amrinone increased cardiac index (CI) and decreased both systemic vascular resistance index (SVRI) and central venous pressure (CVP) more significantly than control value. CONCLUSIONS: In patients with chronic right ventricular failure associated with PH, amrinone may decrease the PAP and improve cardiac performance more effectively than dobutamin does. Increment of dosage of amrinone may not result in significant reduction of PAP.

BACKGROUND: Plasmid-mediated AmpC beta-lactamases (PABLs) have been detected in the strains of Escherichia coli, Klebsiella spp., Proteus mirabilis, and Salmonella spp. PABLs may be difficult to detect and might interfere in the therapeutic and infection-control processes. Although several PABL-detection methods based on phenotypes have been reported, the Clinical and Laboratory Standards Institute currently does not recommend a routine detection method for PABLs. The aim of this study is to compare the performances of 3 phenotypic PABL detection methods. METHODS: Total 276 non-duplicated clinical isolates of E. coli (N=97), K. pneumoniae (N=136), and P. mirabilis (N=43) were collected from 14 hospitals in Korea between April and June 2007 in a non-consecutive and non-random manner. Multiplex PCR was performed to detect the PABL genes. Further, 3 phenotypic detection methods-cephamycin-Hodge test, Tris-EDTA (TE) disk test, and combination-disk test with 3-aminophenylboronic acid (BA)-were performed using cefoxitin and cefotetan disks. RESULTS: PABL genes were detected by multiplex PCR in 122/276 isolates, including 14/97 E. coli, 105/136 K. pneumoniae, and 3/43 P. mirabilis isolates. The combination-disk test with BA showed higher sensitivity (98.4%), specificity (92.2%), and efficiency (96.3%) than the cephamycin-Hodge (76.2%, 96.1%, and 88.6%, respectively) and the TE-disk (80.3%, 91.6%, and 87.9%, respectively) tests. CONCLUSIONS: The combination-disk test with BA is a simple, efficient, and interpretable test that can be applicable in clinical laboratories involved in the detection of PABLs in clinical isolates of E. coli, K. pneumoniae, and P. mirabilis.

BACKGROUND: Arterial pressure is the most commonly utilized guideline for the management of critically ill patients. However, the site of arterial pressure monitoring can impact the observed pressure. In patients undergoing cardiac surgery, peripheral arterial pressure can underestimate central aortic pressure and vasodilators magnify this phenomenon. There was also a large discrepancy between radial and femoral artery pressure in endotoxemic patients treated with vasopressors or hypothermic patients. We evaluated the effect of the continuous infusion of norepinephrine, the most commonly used vasopressor, on pressure and blood flow in both the brachial and femoral artery in dogs in normal condition. METHODS: Both the brachial and femoral arteries were cannulated for pressure monitoring and the other side arteries were exposed for the measurement of blood flow in 10 dogs. Two doses of norepinephrine (NE), 0.05 microgram/kg/min and 0.1 microgram/kg/min, were infused for 10 minutes each in sequence. Hemodynamic variables and blood flow were measured before the infusion of NE, and immediately after the infusion of the two doses of NE. RESULTS: NE increased both brachial and femoral arterial pressures with no difference between the two pressures. NE decreased blood flow in both brachial and femoral arteries even though cardiac output was maintained constantly which means NE caused the redistribution of blood flow. CONCLUSIONS: Unlike endotoxemic shock conditions or hypothermic vasoconstriction, NE didn't show different effects on pressure monitoring sites regardless of their diameter in normal condition. NE increased blood pressure and decreased blood flow in the same degree in both the brachial and femoral artery.
