Bariatric surgery in over 60 years old patients: is it worth it?

The high prevalence of obesity in the elderly and the increase in life expectancy pushed up the age limit as an indication to bariatric surgery. Nevertheless, results on safety and effectiveness of these procedures in over 60 years old population are still controversial. Objectives of the study were to evaluate the safety and effectiveness of bariatric surgery in the elderly.

Impact of Tissue Enolase 1 Protein Overexpression in Esophageal Cancer Progression.

Enolase (ENO) 1 is a key glycolytic enzyme and important player in tumorigenesis. ENO1 overexpression has been correlated with tumor progression and/or worse prognosis in several solid malignancies. However, data concerning the impact of ENO1 in cancer conflict.

Abnormal expression of Endoglin and its receptor complex (TGF-β1 and TGF-β receptor II) as early angiogenic switch indicator in premalignant lesions of the colon mucosa.

The precise timing of the angiogenic switch in colorectal cancer development is still unclear. The simultaneous expression of Endoglin (CD105), transforming growth factor (TGF)-β1 and TGF-β receptor (R) II were quantified in surgical specimens comprising normal human colon, pre-malignant dysplastic tissue, in situ, and invasive colon cancer specimens, at mRNA and protein levels, respectively by real-time PCR and immunohistochemistry. Serum concentrations of soluble Endoglin and TGF-β1 were evaluated.

The diagnostic accuracy of the immunocytochemical markers in the pre-operative evaluation of follicular thyroid lesions.

Unlabelled: Aim of the study was to consider the diagnostic accuracy of galectine-3 (GAL3) in the pre-operative cytological evaluation of follicular lesions.

Materials And Methods: We retrospectively evaluated 100 patients suffering from thyroid nodular disease submitted to thyroidectomy from 2006 to 2007 in our Institution. Before surgery all patients underwent fine needle aspiration biopsy.

Carcinosarcoma of the esophagogastric junction.

Carcinosarcoma of the esophagus and the stomach are rare neoplasms characterized by the simultaneous presence of carcinomatous and sarcomatous elements. There is no report in the literature of carcinosarcoma of the esophagogastric junction. We present a case of carcinosarcoma of the esophagogastric junction whose unique clinical presentation, surgical issues, morphological and immunohistochemical features makes it quite distinctive from similar cases observed in the esophagus or in the stomach.

Successful surgical management of a delayed pharyngo-esophageal perforation after anterior cervical spine plating.

A case report of a 41-year-old man who had a delayed pharyngo-esophageal perforation without instrumentation failure 7 years after anterior cervical spine plating is presented and the literature on this issue is reviewed. This injury resulted from repetitive friction/traction between the retropharyngo-esophageal wall and the cervical plate construct leading to a pseudodiverticulum and perforation. Successful treatment of the perforation was obtained after surgical repair using a sternocleidomastoid muscle flap.

Transforming growth factor-beta binding receptor endoglin (CD105) expression in esophageal cancer and in adjacent nontumorous esophagus as prognostic predictor of recurrence.

Background: We hypothesized that the potent neovascularization marker endoglin (CD105), by differentially highlighting a subset of microvessels (MV) in esophageal cancer (EC), could provide better prognostic/therapeutic information than the panendothelial marker CD34, which also highlights MV.

Methods: Endoglin messenger ribonucleic acid (mRNA) expression in normal, malignant, and adjacent nontumorous esophagus tissue was quantified by real-time reverse-transcription polymerase chain reaction (RT-PCR). Sections of formalin-fixed, paraffin-embedded tissues were analyzed immunohistochemically for CD105 and CD34.

KIT/stem cell factor expression in premalignant and malignant lesions of the colon mucosa in relationship to disease progression and outcomes.

Autocrine/paracrine stimulation of KIT has been observed in colorectal carcinoma (CRC) cell lines. We investigated the expression of KIT and stem cell factor (SCF) in CRC in comparison with premalignant colon lesions and normal colonic mucosa to assess the prognostic and therapeutic relevance of this receptor/ligand system in CRC. Transcript levels of c-kit and the two SCF splicing variants were determined quantitatively by real-time RT-PCR using cDNA obtained from normal, premalignant and malignant snap frozen colon tissue specimens.

Giant fibrovascular polyp of the esophagus.

Giant fibrovascular polyps are uncommon benign esophageal tumors almost always originating from the cervical esophagus, frequently from the upper esophageal sphincter. The case of a 74-year-old man with a long history of dysphagia and a weight loss of 9 kg is presented. Neither barium esophagogram, computed tomogram or magnetic resonance imaging correctly evidenced the lesion.

[The choice of surgical therapy in adenocarcinoma of the cardia].

Aim: From 1996 the adenocarcinoma of the esophago-gastric junction (AEG) is divided into 3 types according to Siewert's classification. For AEG type I and III the surgical treatment is codified, while for type II is still controversial. The aim of our study is to understand what is the better surgical treatment for AEG type II.

[Adenocarcinoma of the cardia: surgical strategies compared].

Background: The incidence of adenocarcinoma of the cardia is increasing. The choice of surgical strategy for AEG type II of Siewert classification is the subjects of controversial discussion. The aim of our retrospective study is to analyse the surgical results in 12 years.
