Aim and background. Neoadjuvant treatment for rectal adenocarcinoma improves local control and represents the standard for locally advanced disease. Laparoscopic and robotic total mesorectal excision has been increasingly adopted. It provides magnified visualization of the pelvic cavity, thereby facilitating the mesorectal dissection. Methods. Consecutive patients with locally advanced/ultralow rectal adenocarcinoma received neoadjuvant treatment and mini-invasive total mesorectal excision at our center. We retrospectively reviewed the clinical records by using a prospectively collected data base and focusing on feasibility, tumor response and treatment outcomes. Results. In a 13-year period, 117 rectal adenocarcinoma patients (80 males and 37 females) received neoadjuvant treatment and mini-invasive total mesorectal excision. Median age at diagnosis was 67 years; pre-treatment stage was I in 10 (9%); IIA in 58 (50%); IIC in 5 (4%); IIIA in 10 (9%); IIIB in 31 (26%) and IV in 3 (2%) patients. All patients received external beam radiation therapy, 79 (67%) combined with fluorouracil- based chemotherapy. One-hundred and three patients underwent laparoscopic surgery and 14 robotic surgery. Overall, 90 patients (77%) had anterior resection and 27 (23%) had abdominoperineal resection. Down-staging was obtained in 70 patients (66%). No major intraoperative nor delayed surgical complications were observed. At a median follow up of 52 months, 8 patients (7%) had a local relapse, 7 of them along with distant relapse, and 16 (14%) had distant relapse. The 5-year relapsefree survival was 76.5%. Conclusions. Our data suggest that in a community hospital mini-invasive surgery after neoadjuvant treatment is feasible in real clinical practice and achieves consistent results in term of disease control rate. © II Pensiero Scientifico Editore downloaded by EXCERPTA MEDICA.

Background: Ingestion and/or aspiration of foreign bodies (FB) are avoidable incidents. Children between 1 and 3. years are common victims for many reasons: exploration of the environment through the mouth, lack of molars which decreases their ability to properly chew food, lack of cognitive capacity to distinguish between edible and inedible objects, and tendency to distraction and to perform other activities, like playing, whilst eating. Most FBs are expelled spontaneously, but a significant percentage impacts the upper aerodigestive tract. Approximately 80% of children's choking episodes are evaluated by pediatricians. The symptoms of aspiration or ingestion of FBs can simulate different paediatric diseases such as asthma, croup or pneumonia, delaying the correct diagnosis. Symptoms: There are three clinical phases both in aspiration and in ingestion of FBs: initial stage (first stage or impaction or FB) shows choking, gagging and paroxysms of coughing, obstruction of the airway (AW), occurring at the time of aspiration or ingestion. These signs calm down when the FB lodges and the reflexes grow weary (second stage or asymptomatic phase). Complications occur in the third stage (also defined as complications' phase), when the obstruction, erosion or infection cause pneumonia, atelectasis, abscess or fever (FB in AW), or dysphagia, mediastinum abscess, perforation or erosion and oesophagus (FB in the oesophagus). The first symptoms to receive medical care may actually represent a complication of impaction of FB. Locations and management: Determining the site of obstruction is important in managing the problem. The location of the FB depends on its characteristics and also on the position of the person at the time of aspiration. Determining the site of obstruction is important in managing the problem. Larynx and trachea have the lowest prevalence, except in children under 1. year. They are linked with the most dangerous outcomes, complete obstruction or rupture. Bronchus is the preferred location in 80-90% of AW's cases. Esophageal FBs are twice more common than bronchial FBs, although most of these migrate to the stomach and do not require endoscopic removal. Diagnosis of FB proceeds following the traditional steps, with a particular stress on history and radiological findings as goal standards for the FB retrieval. The treatment of choice for AW's and esophageal FBs is endoscopic removal. Endoscopy should be carried out whenever the trained personnel are available, the instruments are checked, and when the techniques have been tested. The delay in the removal of FBs is potentially harmful. The communication between the endoscopist and the anaesthesiologist is essential before the procedure to establish the plan of action; full cooperation is important and improves the outcome of endoscopy. Conclusions: Ingestion and or aspiration of FB in children are multifactorial in their aetiology, in their broad spectrum of different resolutions for the same FB and in the response of each patient to the treatment. Prevention remains the best treatment, implying an increased education of parents on age-appropriate foods and household items, and strict industry standards regarding the dimensions of toy parts and their secure containers. © 2012.

Purpose: To evaluate the role of smoking in Barrett’s esophagus (BE) and erosive esophagitis (E) compared to endoscopic controls with no BE or E. Smoking is considered a cause of both BE and E, but results on this topic are quite controversial. Methods: Patients with BE (339), E (462) and controls (619: 280 with GERD (gastroesophageal reflux disease)-negative and 339 with GERD-positive anamnesis) were recruited in 12 Italian endoscopy units. Data were obtained from structured questionnaires. Results: Among former smokers, a remarkable upward linear trend was found in BE for all smoking-related predictors. In particular, having smoked for more than 32 years increased the risk more than two times (OR 2.44, 95 % CL 1.33–4.45). When the analysis was performed in the subgroup of subjects with GERD-negative anamnesis, the risk of late quitters (<9 years) passed from OR 2.11 (95 % CL 1.19–3.72) to OR 4.42 (95 % CL 1.52–12.8). A noticeably positive dose–response relationship with duration was seen also among current smokers. As regards E, no straightforward evidence of association was detected, but for an increased risk of late quitters (OR 1.84, 95 % CL 1.14–2.98) in former smokers and for early age at starting (OR 3.63, 95 % CL 1.19–11.1) in GERD-negative current smokers. Conclusions: Smoking seems to be an independent determinant of BE and, to a lesser degree, of E. The elevation in risk is independent from GERD and is already present in light cigarette smokers. Smoking cessation may reduce, but not remove this risk. © 2014, Springer International Publishing Switzerland. Source

Context While several articles describe clinical management of Foreign Bodies injuries in the upper air tract, little epidemiological evidence is available from injury databases. Objective This article aims to understand the burden of airway FB injuries in high-, low-, and middle-income countries as emerging from scientific literature. Data Sources One thousand six hundred ninety-nine published articles 1978-2008. Study Selection A free text search on PubMed database ((foreign bodies) or (foreign body)) and ((aspiration) or (airways) or (tracheobronchial) or (nasal) or (inhalation) or (obstruction) or (choking) or (inhaled) or (aspirations) or (nose) or (throat) or (asphyxiation)) and ((children) or (child)). Data Extraction Information on reported injuries according to country, time period, children sex and age, FB type, site of obstruction, symptoms, signs, diagnostic and therapeutic procedures, delay at the diagnosis, complications, number of deaths. Results Serious complications occur both in high-income and low-middle income countries in a considerable proportion of cases (10% and 20%, respectively). Similarly, death is not infrequent (5-7% of cases). Conclusions Few countries have good systematic data collection and there's a lack of sensibility in parents and clinicians in terms of acknowledge of the choking risk. On the contrary, international surveillance systems able to collect information in a standardized way need to be implemented. © 2012 Wiley Periodicals, Inc. Source

Helicobacter pylori is an extra macro- and microdiverse bacterial species, but where and when diversity arises is not well-understood. To test whether a new environment accelerates H. pylori genetic changes for quick adaptation, we have examined the genetic and phenotypic changes in H. pylori obtained from different locations of the stomach from patients with early gastric cancer (ECG) or chronic gastritis (CG). Macroarray analysis did not detect differences in genetic content among all of the isolates obtained from different locations within the same stomach of patients with EGC or CG. The extent and types of functional diversity of H. pylori isolates were characterized by 2-D difference gel electrophoresis (2D DIGE). Our analysis revealed 32 differentially expressed proteins in H. pylori related to EGC and 14 differentially expressed proteins in H. pylori related to CG. Most of the differentially expressed proteins belong to the antioxidant protein group (SodB, KatA, AphC/TsaA, TrxA, Pfr), tricarbon acid cycle proteins (Idh, FrdA, FrdB, FldA, AcnB) and heat shock proteins (GroEL and ClpB). We conclude that H. pylori protein expression variability is mostly associated with microorganism adaptation to morphologically different parts of the stomach, which has histological features and morphological changes due to pathological processes; gene loss or acquisition is not involved in the adaptation process. © 2010 American Chemical Society.
