Solitary Adrenal Metastasis from Esophageal Adenocarcinoma: A Case Report and Review of the Literature

Introduction. In patients with extra-adrenal malignancy, an adrenal mass necessitates investigating the possibility of metastatic tumor. Curable adrenal metastasis are considered as a rare event. Case report. A 52-year-old male suffering from lower esophageal adenocarcinoma with a solitary left adrenal metastasis is presented herein, who underwent concomitant transhiatal esophagectomy and left adrenalectomy. The patient remains disease-free 18 months later. Discussion. Adrenal metastases mostly occur in patients with lung, kidney, breast, and gastrointestinal carcinomas. Primary esophageal adenocarcinoma gives adrenal metastatic deposits according to autopsy series with an incidence of about 3%–12%. When no other evidence of metastatic disease in cancer patients exists, several authors advocate adrenalectomy with curative intent. Isolated cases of long-term survival after resection of solitary adrenal metastasis from esophageal adenocarcinoma, like in our case, have been reported only as case reports. Conclusion. This study concludes that surgical resection may result in survival benefit in selected patients with solitary adrenal metastasis from esophageal adenocarcinoma

Concurrent insulinoma and pancreatic adenocarcinoma: report of a rare case and review of the literature

Pancreatic adenocarcinoma is the 5th leading cause of cancer-related death in Western countries and insulinomas are rare endocrine neoplasms of the pancreas. The concurrent appearance of pancreatic adenocarcinoma and insulinoma is very rare and to the best of our knowledge has never been reported again. Herein, we present such an occurrence in a 74-year-old man. Resection of a mass in the uncinate process of the pancreas revealed pancreatic adenocarcinoma with severe desmoplastic reaction. Two years later, due to symptomatology persistence the patient was re-examined and a new 2cm mass in the uncinate process was found leading to surgery, which demonstrated a 2cm endocrine islet-cell tumor. Establishing a diagnosis in patients with insulinoma is difficult and the imaging studies still have low sensitivity and specificity except for intra-operative ultrasonography, which is the most accurate method detecting 90% of these lesions

Identity as space: Localism in the Greek protests of Syntagma Square

The paper studies the textual, discursive and social practices of the Greek "aganaktismeni" (indignados) movements, which mainly took place in the public gathering of tens of thousands of Greeks in Syntagma Square, outside the Greek parliament from May to August 2011. Data come from multiple sources, including the General Assembly proceedings and resolutions, while a linguistically-informed approach is followed, which combines Critical Discourse Analysis concepts with corpus linguistic methods. It is argued that the Syntagma protests generated a new context in Greek politics, by introducing new genres and the innovative articulation of already existing discourses. It was also found that social/political identities and social/public space were co-articulated, since the identity of the movement was crucially constructed in terms of space. © John Benjamins Publishing Company

The role of microRNAs in liver cancer

Hepatocellular carcinoma and cholangiocarcinoma constitute the majority of primary malignant tumors located in the liver, with hepatocellular carcinoma accounting for approximately 80% of these tumors and cholangiocarcinoma representing the remaining 20%. Both are aggressive malignancies, heterogeneous in terms of biological activities and clinical behavior, with dismal outcomes and an increasing incidence worldwide. Radical surgical resection remains the gold standard to date, as adjuvant therapeutic modalities have failed to show a consistent and adequate curative response. However, radical surgical resection is not feasible in most of the patients with such tumors, as tumor size or functional status of the parenchyma does not permit extended hepatic resection. In addition, patients who undergo curative resection often have a high rate of relapse. Multimodal therapeutic approaches, such as the combination of invasive methods (surgical resection, radiofrequency ablation, and two-step or three-step procedures with intermittent portal vein embolization) with interferon-α, systemic chemotherapy, or transarterial catheter embolization, may prolong survival in some patients, but have, however, failed to demonstrate satisfactory results. Therefore, an obvious need emerges for the discovery of new biomarkers to understand the events leading to hepatocarcinogenesis, to relate different phenotypes with differences in clinical behavior and prognosis, and, if possible, to predict response rates to adjuvant therapeutic modalities or, furthermore, to establish novel mechanism-based treatments for hepatic tumors. © 2012 Wolters Kluwer Health | Lippincott Williams & Wilkins

A Tailored Approach to the Management of Perforations Following Endoscopic Retrograde Cholangiopancreatography and Sphincterotomy

Background: The management of endoscopic retrograde cholangiopancreatography (ERCP)-related perforations remains controversial. The aim of the study was to determine the incidence of perforations following ERCP, their characteristics, operative and non-operative management options and clinical outcome. Methods: A retrospective review of ERCP-related perforations, during a 21-year period, was performed. Each perforation was categorized into types I to IV according to the location, mechanism and radiographic evaluation of the injury. Comparisons were made between patients treated operatively and non-operatively. Results: Forty-four perforations (0. 4%) occurred in 9,880 procedures. They were mainly caused by the passage of the endoscope (type I) in 7 (16%) and sphincterotomy (type II) in 30 (68%) patients. The management was non-operative in 32 (72%) and operative in 12 patients. In multivariate analysis, only the type of perforation (type I: endoscope-related) was found significant for predicting operative treatment. The hospital stay was longer for patients requiring an operation (median, 24 vs 9 days). The overall mortality was 2/44 (4. 5%). There was no death in the non-operative group. Conclusions: The need for immediate operative intervention should be based on the type of injury and clinical findings. Patients with type I perforations should be treated surgically and primary repair should be tried. Patients with type II injuries may be treated initially non-operatively. Delayed operative intervention will be required in a minority of these patients. © 2011 The Society for Surgery of the Alimentary Tract

Expression of microRNAs, miR-21, miR-31, miR-122, miR-145, miR-146a, miR-200c, miR-221, miR-222, and miR-223 in patients with hepatocellular carcinoma or intrahepatic cholangiocarcinoma and its prognostic significance

MicroRNAs are a class of non-coding molecules found to regulate a variety of cellular functions in health and disease. Dysregulation of microRNAs is involved in liver disease, especially hepatocarcinogenesis. Since primary hepatic malignancies are typically characterized by late diagnosis, frequent recurrence, and poor response to adjuvant therapy, there is a need for the discovery of novel biomarkers in order to achieve earlier diagnosis, predict tumor aggressiveness and response to adjuvant therapy. The purpose of this study is to evaluate the expression of certain microRNAs (miR-21, -31, -122, -145, -146a, - 200c, -221, -222 and -223) in patients with hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC), as well as to assess their prognostic significance. Micro-RNA expression was assessed by reverse transcription and real-time PCR (RT-PCR). Clinicopathological data and survival rates were retrieved and analyzed. According to our results, miR-21, miR-31, miR-122, miR-221, miR-222 were significantly up-regulated in HCC tissues, whereas miR-145, miR-146a, miR-200c, and miR-223 were found to be down-regulated. Concerning ICC samples, miR-21, miR-31, and miR-223 were found to be over-expressed, whereas miR-122, miR-145, miR-200c, miR-221, and miR-222 were down-regulated. Additionally, expression of miR-21, miR-31, miR-122, and miR-221 in HCC correlated with cirrhosis, while miR-21 and miR-221 associated with tumor stage and poor prognosis. In ICC tissues, miR-21, miR-31, and miR-223 were found to be over-expressed, but no correlation with clinicopathological features was found. © 2011 Wiley Periodicals, Inc

Methods of safe laparoscopic cholecystectomy for left-sided (sinistroposition) gallbladder: A report of two cases and a review of safe techniques

INTRODUCTION: Left-sided gallbladder is a rare anatomical variation. Usually it is discovered intra-operatively and is accompanied by anatomic variations that can prove quite challenging during laparoscopy. PRESENTATION OF CASE: From a total of almost 3000 laparoscopic cholecystectomies performed in our institution, two cases of left sided gallbladder were unexpectantly identified intraoperatively. There were no indications for the ectopy preoperatively. In both cases modifications of the standard laparoscopic technique were mandatory. They were performed safely with no post-operative complications. Modifications consisted of transposition of the subxiphoid entry port and alteration in the direction of traction of the rest of the graspers. A review of the literature for methods of safe laparoscopic cholecystectomy was conducted. DISCUSSION: The surgeon must be aware of the anatomic variances in the rare occasion of a left sided gallbladder, since preoperative diagnosis is very difficult. CONCLUSION: Knowledge of potential hazards and modifications of laparoscopic technique is mandatory in order to avoid complications. © 2014 The Authors.
