The effects of glucocorticoids on acute pancreatitis (AP) have remained contradictory. The aim of this study was to investigate the time courses of the effects of the exogenous glucocorticoid agonists dexamethasone (DEX) and hydrocortisone (HYD) and a glucocorticoid antagonist (RU-38486) and to characterize the local and systemic responses in AP in rats.(More)
Objective and design: The consequences of Kupffer cell phagocytosis blockade were studied in endotoxemic rats with obstructive jaundice.¶Material or Subjects: 159 male Wistar rats.¶Treatment: Obstructive jaundice was induced by bile duct ligation (BDL). Gadolinium chloride (1 mg/100g iv) was given 6 days after BDL to inhibit Kupffer cell activity and the(More)
OBJECTIVES To investigate the consequences of treatment with an exogenous glucocorticoid agonist (methylprednisolone) and antagonist (RU-38486) on the local and systemic responses in L-arginine-induced acute pancreatitis in rats. METHODS The methylprednisolone and RU-38486 were administered just before pancreatitis induction. Plasma amylase activity,(More)
Barogenic esophageal injury or Boerhaave syndrome is an esophageal perforation entailing very high mortality and morbidity. Endoscopic techniques have been introduced in the treatment of various types of esophageal perforation. This report describes the first patient who underwent a successful endoscopic clipping involving sealing of a transpleural(More)
Neoadjuvant (preoperative) therapy and combined modality therapy have become focuses of interest in the effort to prolong survival and to reduce recurrence rates in patients with esophageal cancer. Staging of the tumor is a critical step in establishing which therapeutic option is appropriate. Once surgical management is advocated, adequate medical imaging(More)
BACKGROUND/AIMS Neoadjuvant chemoradiotherapy (CRT) is widely applied in locally advanced esophageal tumors to improve resectability and local tumor control. In this study, we retrospectively analyzed the perioperative course of patients who underwent esophagectomy or esophagectomy following CRT. METHODOLOGY Forty one patients were admitted with(More)
Therapy for breast cancer today is characterised by ever more precise diagnostic methods and ever more effective oncological treatments, a trend which will certainly continue into the future. Breast preservation and the application of oncoplastic principles are increasingly popular. A sentinel lymph node biopsy in the surgical treatment of the axilla is(More)
CASE REPORT A 25-year-old primipara, in the thirty-second week of her pregnancy observed a nodule in the upper outer quadrant of her left breast during self-examination. Complex breast examination revealed calcification with 4 cm of diameter. Ductal malignant cells (C5) were identified by fine-needle aspiration biopsy, while core biopsy verified invasive(More)
The aim of this retrospective study was to determine the rate of sentinel lymph node (SLN) positivity in patients with a final diagnosis of ductal in situ cancer (DCIS) of the breast. Between October 2002 and January 2007, 57 patients with DCIS underwent wide excision after radio-guided lesion localization; 53 of them (53/57, 93%) had participated in(More)
