Polysorbate 80, a sorbitan derivate, is a surfactant used as an emulsifier in some foods in concentrations of up to 0.5%. It was recently shown in vitro that polysorbate 80 decreases the minimum bactericidal concentrations of clarithromycin and metronidazole and may also revert antibiotic resistance.

Pocket-size ultrasound devices (PSUD) are now widely available becoming a useful tool for diagnostic and therapeutic purposes. We aim to investigate the accuracy of PSUD in diagnosing cholelithiasis as compared to traditional ultrasonography. Moreover, we tested the reliability of PSUD when performed by inexperienced internal medicine residents after a short-term training.

Background: A clinically meaningful impairment of bone mass secondary to malabsorption is frequent in untreated celiac disease. In adult patients, a rigorous gluten-free diet (GFD) significantly improves, but does not always normalize, bone mineral density (BMD). The reason for this marginal response is unclear.

Background: The relationship between gluten ingestion and gastrointestinal tract function is a matter of debate.

Aim: We analysed the effect of gluten on gastric and gallbladder emptying and intestinal fermentation in healthy volunteers.

Methods: Ultrasound measurement of gastric and gallbladder emptying after both gluten-containing and gluten-free meals was performed in 18 volunteers (8 women, age 25.

Objectives: The role of colonic methane production in functional bowel disorders is still uncertain. In small samples of irritable bowel syndrome (IBS) patients, it was shown that methane breath excretion correlates with clinical presentation and delayed gastrointestinal transit time. The aim of this study was to evaluate the relationship between intestinal production and breath excretion of CH4 and to correlate CH4 production with the presence and the severity of symptoms, in a large cohort of IBS patients and in a group of healthy volunteers.

Objectives: Little information is available on the mechanisms responsible for dyspeptic symptoms in postprandial distress syndrome (PDS), characterized by the presence of prevalently meal-related early satiation and fullness, and the epigastric pain syndrome (EPS), characterized by the prominent symptom of epigastric pain, generally not meal related. In a group of PDS patients, the presence of hypersensitivity to gastric distension in both fasting and postprandial phases was described as the main pathophysiological mechanism; on the contrary, we have no information on the pathophysiology of EPS.

Methods: Sixty Helicobacter pylori (HP)-negative, irritable bowel syndrome (IBS)-negative, and gastroesophageal reflux disease (GERD)-negative patients with functional dyspepsia according to Rome III criteria underwent symptom, anxiety, depression, and somatization evaluation, gastric barostat test, and gastric emptying time evaluation for solids.

Osteoporosis affects many patients with celiac disease (CD), representing the consequence of calcium malabsorption and persistent activation of mucosal inflammation. A slight increase of fracture risk is evident in this condition, particularly in those with overt malabsorption and in postmenopausal state. The adoption of a correct gluten-free diet (GFD) improves bone derangement, but is not able to normalize bone mass in all the patients.

Background: The aim of this study was to investigate the prognostic role of diagnostic delay and clinical presentation (regarding pain, jaundice, and weight loss) in pancreatic carcinoma.

Methods: One hundred and seventy patients with pancreatic cancer were diagnosed and treated in the decade 2001-2010 (100 males and 70 females, with a mean age of 65.8 years [range, 36-91]).

We verified whether early resistance to treatment can be predicted in a subset of patients with very favourable, early stage Hodgkin lymphoma, treated with VBM (vinblastine, bleomycin and methotrexate) chemotherapy and involved-field radiotherapy, an effective combination with very low early and late toxicity. The relative tumour burden (rTB) was volumetrically measured from the staging computed tomography and analysed together with the parameters of pre-therapy evaluation in 61 patients enrolled into the protocol MH-1b of the Gruppo Italiano Studio Linfomi between 1996 and 2003. Early failure, codified by either less than complete remission (i.

The relative tumor burden (rTB), the tumor burden normalized to body surface area, is of prime clinical and prognostic value in Hodgkin's lymphoma. However, its measurement is rather complicated and a bedside computation cannot be proposed. We investigated the possibility of estimating, instead of measuring, rTB from elementary parameters of the initial staging.

The purpose of the work was to investigate the factors predicting early resistance to treatment in Hodgkin lymphoma. Many staging parameters, including relative tumour burden (rTB), were analysed in 246 patients with Hodgkin lymphoma in relation to early failure, that is, less than complete remission (i.e.

The issue of whether carcinoma of the gastroesophageal junction (GEJ) should be considered a distal esophageal, a proximal gastric or an independent tumor, at least with regards to clinical evaluation and management remains controversial. This study included 613 retrospective consecutive patients with carcinoma of the upper digestive tract, 64 of the esophagus, 58 of the GEJ and 491 of the stomach. The prognostic impact of the main clinical and histological parameters was analyzed in relation to relative survival as an estimate of the excess mortality.

A standard therapeutic approach for advanced malignant thymoma has yet to be defined given the rarity of this condition. We present a patient with advanced thymoma, evaluated as inoperable at diagnosis due to multiple serosal metastases. The strong constitution and determination of the patient allowed treatment with six distinct and subsequent chemotherapy regimens, all administered on an outpatient basis.

Purpose: The current TNM classification is still unsatisfactory for collecting all the prognostic information from the clinical presentation of early gastric cancer: "T" is limited to two levels, the classes of "N" are still wide and "M" is generally absent.

Patients And Methods: This study involved 99 patients who underwent radical gastric resection for early gastric cancer. Clinical and histological parameters were prognostically analyzed for both observed and relative survival.

Autologous stem cell transplantation is the standard care for patients with relapsed or refractory aggressive non-Hodgkin lymphomas. Of the patients who are sensitive to second-line chemotherapy, approximately 40-50% are likely to be cured using this approach. The optimal salvage regimen for pre-transplant debulking is controversial and these second-line chemotherapies are particularly important for patients who cannot undergo transplantation for various reasons including age, comorbidity and insufficient stem cell collection.
