PURPOSE: Metastatic biliary tract cancer (mBTC) has a dismal prognosis. In this study, an independent dataset of patients with mBTC was used to implement and validate a routine clinico-laboratory parameter-based scoring model for risk group identification. MATERIALS AND METHODS: From September 2006 to February 2015, 482 patients with mBTC were assigned randomly (ratio, 7:3) into investigational (n=340) and validation datasets (n=142). The continuous variables were dichotomized using a normal range or the best cutoff values determined using the Contal and O'Quigley statistical methods. Following a Cox’s proportional hazard model, the scoring model was derived by summing the rounded chi-square scores for the factors identified by multivariate analysis. RESULTS: The performance status (Eastern Cooperative Oncology Group 3-4), hypoalbuminemia (< 3.4 mg/dL), carcinoembryonic antigen (≥ 9 ng/mL), neutrophil-to-lymphocyte ratio (≥ 3.0), and carbohydrate antigen 19-9 (≥ 120 U/mL) were identified as independent prognosticators (Harrell’s C index, 0.682; integrated area under the curve, 0.653). Survival was clearly correlated with the risk groups (low, intermediate, and high, 14.0, 7.3, and 2.3 months, respectively; p < 0.001). The prognosis was also discriminative in the validation data set (median survival, 16.7, 7.5, and 1.9 months, respectively; p < 0.001). Chemotherapy did not offer any survival benefits for high-risk patients. CONCLUSION: These proposed prognostic criteria for mBTC can facilitate accurate patient risk stratification and treatment-related decision-making.

BACKGROUND: The pathophysiology of acute respiratory distress syndrome with sepsis is acute lung injury (ALI) that's' caused by endotoxin (LPS). We evaluate effects of moxifloxacin on LPS-induced ALI in a rat model. MATERIAL AND METHOD: The rats were divided into 3 groups as the control group (C), the LPS insult group (L), and the LPS+moxifloxacin treated group (L-M). ALI was induced by endotracheal instillation of E.coli LPS, then moxifloxacin was given in 30 minutes. Five hours later, we checked the lung weight/body weight ratio(the L/BW ratio), the protein & neutrophils in the bronchoalveolar lavage fluid (BALF), the myeloperoxidase (MPO) activity & the malondialdehyde (MDA) content, the expressions of cytosolic and secretory phospholipase A2 (c, sPLA2), and the morphology of the lung with using a light microscope. RESULT: The L/BW ratio, the protein content and the neutrophil count in the BALF, and the MPO activity and the MDA content in lung were significantly increased in group L compared to group C, and these factors were markedly decreased in group L-M compare to group L. The cPLA2 expression and the sPLA2 expression were increased in group L and the cPLA2 expression was decreased in group L-M. Yet the sPLA2 expression was not changed in group L-M. Morphologically, many inflammatory findings were observed in group L, but not in group L-M. CONCLUSION: Many of the inflammatory changes of ALI that were caused by LPS insult were ameliorated by moxifloxacin treatment.

Patients with isolated congenitally corrected transposition of the great arteries (CCTGA) comprise 1% of all CCTGA patients. They are usually asymptomatic until functional abnormalities such as atrioventricular block or systemic atrioventricular valve regurgitation become complicated. We report here a case of a 33 year-old man with isolated CCTGA and complete AV block that underwent implantation of a permanent pacemaker using endocardial leads. During a 12 month follow-up period, no symptoms developed and lead-related parameters have been stable.

Flexible fiberoptic colonoscopy is extensively used for the diagnosis and management of colorectal disease. Many possible complications can occur. The most common and most serious complications are hemorrhage, perforation and respiratory problems. Colonic perforation usually results in a fatal and emergent condition. However, management of iatrogenic colonic perforation has been controversial. The choice between the medical versus the surgical approach has been dependent on the mechanism of the perforation, bowel preparation, location, size of the defect and severity of symptoms. We report here a case where colonic perforation emerged during endoscopic submucosal resection of a rectal tumor. The rectal perforation was accompanied with pneumoperitoneum, subcutaneous emphysema, pneumoretroperitoneum and pneumomediastinum. As the bowel preparation was excellent, intravenous antibiotics and total parenteral nutirition were administered. The patient was treated successfully without any complications.

BACKGROUND: The aim of our study was to optimize and establish erythropoietin (EPO) enzyme linked immunosorbent assay (ELISA) system. METHODS: We prepared several monoclonal and polyclonal antibodies specific to human-EPO. The best combinations of antibodies for coating and detecting antibodies were selected for the establishment of ELISA. We tested several methods such as a competitive EIA and a sandwich ELISA. RESULTS: The best sandwich ELISA was optimized compared to competitive EIA when purified polyclonal antibody (PoAb) was used as a coating antibody and biotinylated PoAb as a detecting antibody. This sandwich ELISA easily detected EPO when PoAb pairs were used compared to the ELISA using monoclonal antibody and PoAb. There were no significant differences between the effects of various blocking solutions on the performance of sandwich ELISA using biotinylated antibody. The ELISA system using PBST containing 3% BSA as a blocking solution can sensitively detect EPO (10 mU/mL) in a broad range of EPO concentrations (10-2,000 mU/mL) and there were cross-reactions with other cytokines). CONCLUSIONS: EPO can be easily determined by using biotinylated PoAb as a detecting antibody and another PoAb as a coating antibody.

Invasive aspergillosis needs to be paid extra attention to these day since chemotherapy and stem cell transplantation bring about immune suppression. The lung is the main portal of entry and once involved, invasive aspergillosis may be delivered by hematogenous spread into the central nervous system, liver, spleen, gut and adrenal gland. However infections through the gastrointestinal track are not common. In these cases, abdominal pain and diarrhea can be the major symptoms and amphotericin B is the treatment of choice. We report here on a patient with untreated acute myeloid leukemia who suffered from bloody diarrhea without any lung lesion; this patient had ulcer close to cecum on colonoscopy, and then he was diagnosed as suffering with aspergillosis with H&E staining and PAS staining on the biopsy specimen.

Complications of acute pancreatitis usually occur in pancreas and its contiguous organs. The prevalence of colonic invasion is rare, however, the consequence is fatal, with mortality above 50%. The initial symptoms and onset times are variable and major affected sites are transverse colon and splenic flexure. The spread of inflammatory exudates into the colon is the main mechanism of colonic invasion. If the colonic stenosis develops, it is necessary to manage it surgically. We report a case who arrived at the hospital with watery diarrhea and abdominal distension in the recovery period of acute alcoholic pancreatitis and was diagnosed as a colonic obstruction in the splenic flexure. The patient underwent loop ileostomy instead of the resection of the lesion because of severe adhesion around the splenic flexure. The patient died due to sepsis 5 days after the operation.

Endovascular procedures are becoming the standard type of care for the management of hemodialysis vascular access dysfunction. As with any type of medical procedure, these techniques can result in procedure-related complications, although the expected number of complications is low. The clinical extent of these complications varies from case to case. Management of these cases depends on the clinical presentation. Major complications such as vein rupture, arterial embolism, remote site bleeding or hematoma, symptomatic pulmonary embolism and puncture site complications necessitating treatment require major therapy. Minor complications such as non-flow compromising small puncture site hematoma or pseudoaneurysms require little or no therapy. It is essential that the interventionist be prepared to manage these complications appropriately when they arise.

Sclerosing lymphangitis of the penis is a rare condition involving the distal lymphatics that is characterized by cord-like lesions on the shaft or coronal sulcus. Although the etiology is unknown, its association with mechanical trauma, anatomic variants, or infection has been shown. Clinically, the patient notices a painless, firm, cord-like lesion just proximal to the sulcus. Histologic study reveals hypertrophy and sclerosis of lymphatic vessel walls and, in some cases, thrombus formation within the dilated vessels. Most cases are self-limited, and conservative management is indicated, but surgical excision is warranted for persistently symptomatic lesions. We report three cases of sclerosing lymphangitis of the penis that required treatment by surgical excision.
