Neuroendocrine-Related Circulating Transcripts in Small-Cell Lung Cancers: Detection Methods and Future Perspectives.

No well-established prognostic or predictive molecular markers of small-cell lung cancer (SCLC) are currently available; therefore, all patients receive standard treatment. Adequate quantities and quality of tissue samples are frequently unavailable to perform a molecular analysis of SCLC, which appears more heterogeneous and dynamic than expected. The implementation of techniques to study circulating tumor cells could offer a suitable alternative to expand the knowledge of the molecular basis of a tumor.

Effects of KEAP1 Silencing on the Regulation of NRF2 Activity in Neuroendocrine Lung Tumors.

Background: The KEAP1/NRF2 pathway has been widely investigated in tumors since it was implicated in cancer cells survival and therapies resistance. In lung tumors the deregulation of this pathway is mainly related to point mutations of and genes and promoter hypermethylation, but these two genes have been rarely investigated in low/intermediate grade neuroendocrine tumors of the lung.

Methods: The effects of silencing on NRF2 activity was investigated in H720 and H727 carcinoid cell lines and results were compared with those obtained by molecular profiling of KEAP1 and in a collection of 47 lung carcinoids.

Exogenous Lipoid Pneumonia due to Chronic Inhalation of Oily Product Used as a Lubricant of Tracheotomy Cannula.

Exogenous lipoid pneumonia (ELP) is caused by the inhalation of vaporized oily products. Long-term exposure can result in chronic disease, whereas acute form usually results from massive aspiration of fatty substances. It has an incidence of 1.

Enhanced Recovery After Surgery: a patient centered process.

The Enhanced Recovery After Surgery (ERAS) is a model of care introduced in 1997 by a group of general surgeons from Northern Europe led by Henrik Kehlet. The core of this approach is to produce improvements in surgical patient outcomes, especially in the reduction of hospital stay, complications rate, early recovery and reduction of economic burdens. Simply elaborating and establishing a protocol is not enough and much more efforts and changes are needed to achieve the aim to offer a sustainable improvement in the overall quality of patient care, therefore, ERAS is not a single and rigid protocol but is a method, a "modus operandi", a new way of multidisciplinary teamwork with readiness to make changes as knowledge evolves, i.

Left Supraclavicular Swelling: Sclerosing Perineurioma.

A sclerosing perineurioma presents as a single asymptomatic papule or nodule located on the hands of adult patients; approximately 60 cases have been reported in medical literature since 1997. Histologically, it originates from the perineural cells of the peripheral nerves and presents epithelial membrane antigen (EMA) positivity and S100 protein negativity. Here, we present the case of a 58-year-old male admitted to our surgery unit complaining of left supraclavicular swelling of 1-cm in size, having no significant past medical history.

Esophageal Achalasia: Predictive Value of Preoperative Resting Pressure of LES Correlated with Type of Fundoplication.

Objective: The aim of the present study is to show the predictive value of the preoperative resting pressure of the lower esophageal sphincter (LES) correlated with the type of fundoplication (Nissen or Dor) after Heller myotomy in our series.

Materials And Methods: From January 1998 to June 2010, 88 patients affected by esophageal achalasia underwent surgery at our unit. However, our study focused on a sample of 36 patients, because many data were lost or was never recorded.

The Post-Surgical Long-Term Behaviour of Lung Carcinoid Tumours.

Here, we report a retrospective evaluation of long-term behaviour of lung carcinoids after surgery. A total of 23 patients (17 with typical pulmonary carcinoids and 6 with atypical pulmonary carcinoids) were enrolled in our hospital from April 1994 to July 2009. All patients underwent intervention at the Unit of Surgery and then were followed at the Unit of Oncology.

De Garengeot's Hernia: a Diagnostic Challenge.

Surgical literature defines the case of acute appendicitis in a sac of femoral hernia as de Garengeot's hernia. The diagnosis remains a very hard challenge for surgeon because the symptoms are aspecific and the most effective tools for preoperative evaluation (as abdominal computed tomography and abdominal ultrasound scan) can often be indeterminate or misinterpreted. We report the case of an 85-year-old white male admitted to our unit complaining of a 1-day history of vague abdominal pain, nausea, vomiting, and painful swelling in the right groin.

Nipple-areola-complex sparing mastectomy: five years of experience in a single centre.

This study aimed at assessing the outcomes of nipple-areola-complex-sparing mastectomy (NSM) of breast cancer in a single-centre and single-surgeon series after 5 years of experience. From June 2007 to January 2012, 58 female patients with breast cancer were admitted for NSM at our unit and 55 of these underwent NSM. All patients underwent a preoperative clinical and instrumental evaluation.

Fundoplication after heller myotomy: a retrospective comparison between nissen and dor.

Objective: A retrospective comparison between Nissen and Dor fundoplication after laparoscopic Heller myotomy for achalasia.

Materials And Methods: From 1998 to 2004 a first group of 48 patients underwent Heller myotomy and Nissen fundoplication for idiopathic achalasia (H+N group). From 2004 to 2010 a second group of 40 patients underwent Heller myotomy followed by Dor fundoplication (H+D group).

Hyperthermia in the treatment of post-actinic osteosarcomas: our anecdotal experience.

Irradiation-induced sarcomas are a late sequelae of irradiation therapy. Most sarcomas have been reported to occur after exposure to a radiation dose of 55 Gys and above, with a dose ranging from 16 Gys to 112 Gys. These tumours are very aggressive and an early detection is needed for a timely intervention.

Fibrosing mediastinitis as a cause of right claudication.

Fibrosing mediastinitis is a rare benign disorder caused by proliferation of acellular collagen and dense paucicellular fibrous tissue within the mediastinum. Its precise cause, pathogenesis and links to infectious (such as histoplasmosis or tuberculosis) and non-infectious (such as sclerosing cholangitis) diseases remain speculative. Affected patients present signs and symptoms related to obstruction of mediastinal hollow organs, such as large vessels, esophagus and airways.

Giant esophageal lipoma.

A case of a giant esophageal pedunculated lipoma diagnosed in a 67-year-old male patient with recent onset of dysphagia is reported. Following the initial endoscopic and radiologic evaluation, the diagnosis was suspected by endo-ultrasonography and confirmed by histopathology. The treatment consisted of an esophagotomy with submucosal resection, through a left sided cervical incision.

Ectopic hepatic tissue misdiagnosed as a tumor of lung.

The ectopic or accessory liver lobe is an uncommon congenital anatomic abnormality. It is considered to be the outcome of an abnormal development of liver tissue during embryologic period. In some cases, it may be secondary to a trauma or a surgical operation.
