Heat Shock Proteins exosomal localization and levels in non-tumoral and tumoral thyroid tissues

Exosomes (EXs) secreted from cells to the extracellular environment play an important role in intercellular communication in normality and pathology. In particular, EXs contribute to cancer progression through the modulation of tumor microenvironment. Heat Shock Proteins (Hsps) are implicated in the development of carcinogenic process because they interact with many metabolic and biomolecular mechanisms of cancer cells [1]. Different studies shown that they can be released by tumors cells and that the mechanism of release is mediated by EXs pathway. In this study we performed an immunomorphological and biomolecular analysis to investigate Hsp27, Hsp60, Hsp70, Hsp90 levels expression profile…

Completion axillary lymph node dissection can be avoid in patients with invasive breast cancer and sentinel lymph node micrometastases

The prognostic value of sentinel lymph node (SLN) micrometastases in invasive breast cancer patients is still widely debated. Even if, in the absence of unequivocal guidelines, the axillary lynphadenectomy is not still performed in the routine clinical care of these patients.We have retrospectively analyzed 897 patients with operable invasive breast cancer and clinically negative axillary lymph nodes underwent conservative surgery or total mastectomy with SLN biopsy. Two groups of patients with SLN micrometastases and isolated tumor cells (ITC) were considered, the first one treated with completion axillary dissection, the second one not followed by further surgical axillary procedure. The …

Bipolar electrothermic coagulation (ligasure bipolar vessel sealing system) in thyroid surgery

[Hemostatic effectiveness of TachoSil® patches in radiofrequency assisted minor hepatic resection].

Aim. Intra- and postoperative bleeding represents an extremely serious and frequent complication of hepatic surgery. The aim of this study was to evaluate the effectiveness of TachoSil (R) to improve hemostasis in radiofrequency assisted minor hepatic resection. Methods. Between July 2008 and June 2010, 31 patients underwent radiofrequency assisted minor hepatic resection. At the end of the liver resection a sponge of TachoSil (R) was applied on the liver. Results. The mean intraoperative bleeding from the liver was 56.1 mL (range 0-300 mL). No patients received intra- and postoperative blood transfusion. Surgical drains were removed between the first and the sixth-eight postoperative day. …

Gastro-oesophageal reflux and "epileptic" attacks: casually associated or related? Efficiency of antireflux surgery. A case report

Although a possible link between gastro-oesophageal reflux disease (GORD) and obstructive sleeping apnoea has already been reported in the literature, there has never been any suggestion of an association with epilepsy, and epileptic attacks have not so far been included among gastro-oesophageal reflux disease symptoms. We report the case of a patient with gastro-oesophageal reflux disease associated with a sliding hiatus hernia, a short oesophagus and oesophagitis, who for the last ten years had not only presented the typical symptoms of gastrooesophageal reflux, but also symptoms of obstructive sleep apnoea and epileptic-like attacks occurring occasionally and only during sleep. Partial p…
