Cap-assisted endoscopic mucosal resection of large polyps involving the ileocecal valve.

Standard endoscopic mucosal resection (EMR) is limited with regard to lesions below or involving the ileocecal valve. We describe the treatment and outcomes when using cap-assisted EMR (EMR-C) to remove large laterally spreading tumors (LSTs) with ileal infiltration in seven patients (median age 74 years). Each LST (median size 40 mm) was successfully resected in one session (median procedure time 50 minutes). Intraprocedural and early bleeding occurred in two patients, and delayed hemorrhage in one. Circumferential resection of the ileum caused asymptomatic strictures in six patients, with regression during follow-up for five. We conclude that the novel EMR-C method is a potentially effective treatment for cecal LST involving the distal ileum. Serious complications such as perforation or symptomatic strictures of the ileocecal valve were not observed and any procedure-related bleeding was easily controlled.

Self-expanding plastic stent to palliate symptomatic tissue in/overgrowth after self-expanding metal stent placement for esophageal cancer.

Self-expanding metal stents (SEMS) are used to treat obstructive malignancies of the esophagus or esophagogastric junction; however, a potential complication is recurrent dysphagia because of tissue in/overgrowth. The placement of a second SEMS is one strategy to re-establish patency of the esophageal lumen. We evaluated the safety and efficacy of an alternative and likely less costly approach: placing a self-expanding plastic stent (SEPS) to manage relapsing dysphagia in patients previously treated with a partially covered SEMS. From December 2007 to January 2009, 13 patients previously treated with a SEMS for malignant dysphagia underwent treatment by inserting a SEPS to palliate relapsing dysphagia, as a result of tissue in/overgrowth. Stenosis was located in the upper esophagus in one patient, in the middle in four patients, and in the lower esophagus in eight patients. Clinical evaluation was performed at the time of stent placement, after 1 week, and then, monthly until death. The SEPS was successfully placed in a single treatment session for all patients. No preliminary dilation was required, and no further treatment was necessary for any patient. Before stenting, the median dysphagia score was 4 (range 3-4), and 1 week later the score was 0 for all patients. The resolution of dysphagia persisted until patient death (from tumor progression). The mean survival after the SEPS insertion was 4 months (range 3-8). This case series supports the use of a SEPS to palliate dysphagia from tissue in/overgrowth of a SEMS. Future clinical trials with larger patient samples are warranted.

Vaccination coverage among school children aged 14-15 years in the French department of Sarthe.

OBJECTIVES: Vaccinations are the main pillar of primary prevention for infectious diseases. To guide and prioritize public health interventions, the Regional Health Agency has asked the Prevention, Vaccination, and Screening Center of the Sarthe department to assess vaccination coverage (VC) at the sub-departmental level. The main objective was to measure the VC among school children aged 14-15 years in Sarthe at the sub-departmental level. PATIENTS AND METHODS: We conducted a VC evaluation survey at the administrative district level among school children aged 14-15 years in the Sarthe department during the first quarter of the 2015-2016 school year. RESULTS: Among 2384 randomly selected school children, 1171 were included in the study. At the departmental level, 85% of children were up to date for DTP, 72% for pertussis, 45% for hepatitis B, 31% for meningococcus C, 93% for measles, and 18% of girls had received at least one dose of the HPV vaccine. Vaccination coverage varied by administrative districts. CONCLUSION: At the departmental level, all VC were below national goals. Territorial disparities could be explained by sociodemographic differences or differences in medical practices. This survey allowed us to identify areas and population groups where the CV rate justified public health actions.

Pegylated interferon and ribavirin in re-treatment of responder-relapser HCV patients.

BACKGROUND: The re-treatment of patients who relapse after a course of standard interferon and ribavirin with pegylated interferon alfa-2b plus ribavirin is an open issue. AIMS: To evaluate efficacy and safety of treatment with pegylated interferon alfa-2b plus ribavirin and the role of early HCV-RNA assessment as a predictor of sustained response. PATIENTS: Between May 2001 and December 2002, 242 consecutive patients with chronic hepatitis C were enrolled in an open, regional, multicentre study. Seventy-eight of them were responder-relapsers to a previous course of combination therapy. METHODS: Patients were treated with pegylated interferon alfa-2b (1 microg/kg/week) plus ribavirin (800-1200 mg daily). Qualitative HCV-RNA was performed at week 2. Genotypes 1-4 were treated for 48 weeks, while genotypes 2 and 3 were treated for 24 weeks. RESULTS: We obtained an overall sustained virological response rate of 41.0% (78.6% for patients with genotypes 2-3). CONCLUSION: This treatment schedule prove to be safe and effective in relapsers with genotype non-1 while genotype 1-4 patients had a low rate of sustained virological response. Qualitative virological assessment after 2 weeks may identify patients who are more likely to reach sustained virological response, but it is not a valid tool for a stopping rule approach.

Association between coffee or tea drinking and Barrett's esophagus or esophagitis: an Italian study.

BACKGROUND/OBJECTIVES: Only a few papers have treated of the relationship between Barrett's esophagus (BE) or erosive esophagitis (E) and coffee or tea intake. We evaluated the role of these beverages in BE and E occurrence. SUBJECTS/METHODS: Patients with BE (339), E (462) and controls (619) were recruited. Data on coffee and tea and other individual characteristics were collected using a structured questionnaire. RESULTS: BE risk was higher in former coffee drinkers, irrespective of levels of exposure (cup per day; ⩽1: OR=3.76, 95% CI 1.33-10.6; >1: OR=3.79, 95% CI 1.31-11.0; test for linear trend (TLT) P=0.006) and was higher with duration (>30 years: OR=4.18, 95% CI 1.43-12.3; TLT P=0.004) and for late quitters, respectively (⩽3 years from cessation: OR=5.95, 95% CI 2.19-16.2; TLT P<0.001). The risk of BE was also higher in subjects who started drinking coffee later (age >18 years: OR=6.10, 95% CI 2.15-17.3). No association was found in current drinkers, but for an increased risk of E in light drinkers (<1 cup per day OR =1.85, 95% CI 1.00-3.43).A discernible risk reduction of E (about 20%, not significant) and BE (about 30%, P<0.05) was observed in tea drinkers. CONCLUSIONS: Our data were suggestive of a reduced risk of BE and E with tea intake. An adverse effect of coffee was found among BE patients who had stopped drinking coffee. Coffee or tea intakes could be indicative of other lifestyle habits with protective or adverse impact on esophageal mucosa.

Family physicians and HIV infection.

OBJECTIVE: We aimed to describe the current and desired involvement of family physicians (FPs) in the treatment of HIV patients (screening practices, potential training and patient follow-up) to reduce the duration and frequency of their hospital treatment. MATERIAL AND METHODS: We conducted a descriptive cross-sectional survey between 2011 and 2012 with the support of COREVIH (Regional Coordinating Committee on HIV). We sent a self-assessment questionnaire to all FPs of the Pays de la Loire region to enquire about their HIV screening practices and expectations for the management of HIV patients. RESULTS: A total of 871 FPs completed the questionnaire (response rate: 30.4%). A total of 54.2% said to provide care to HIV patients; the mean number of HIV patients per FP was estimated at 1.4. With regard to HIV screening, 12.2% systematically suggest an HIV serology to their patients and 72.7% always suggest it to pregnant women. About 45.4% of responding FPs said to be willing to manage HIV patients (clinical and biological monitoring, compliance checks and prescription renewal). FPs mainly reported the lack of training and the low number of HIV patients as a barrier to their further involvement in the management of HIV patients. CONCLUSION: The responding FPs provide care to very few HIV patients. They are, however, willing to be more involved in the routine care of these patients. Medical training provided by COREVIH would help improve HIV screening. The management of HIV patients could thus be handed over to willing FPs.

Carditis, intestinal metaplasia and adenocarcinoma of oesophagogastric junction.

Barrett's oesophagus is a precancerous condition in which the normal squamous epithelium is replaced by intestinal metaplasia (IM). IM can then progress through increasingly severe dysplasia to oesophageal adenocarcinoma (EAC). In the gastric cardia the normal gastric mucosa, when inflamed (carditis), can be replaced by IM and can then progress to gastric adenocarcinoma (GAC). The same histopathological sequence can take place on either side of the oesophagogastric junction. Since the location of that junction can be uncertain this can result in confused diagnosis between EAC and GAC. In this review, the diagnostic criteria, incidence and risk factors for Barrett's oesophagus and carditis are discussed, together with the factors determining the risk of progression to adenocarcinoma of the oesophagus or cardia. The risk factors include familial/genetic, environmental and dietary characteristics. Finally, these risk factors are discussed within the context of cancer prevention.

Post-international adoption medical follow-up at the Angers university hospital between 2009 and 2012.

OBJECTIVE: The authors had for aim to describe infectious diseases in internationally adopted child at arrival in France. PATIENTS AND METHODS: We made a retrospective descriptive study of the children's files having undergone medical check-ups between 2009 and 2012. RESULTS: One hundred and eighty-two files were included: 80% of the children came from Africa, 15% from South America and the Caribbean, 3% from Asia, and 2% from Europe. Forty-three percent were diagnosed with tinea. HIV, hepatitis C, and syphilis blood tests were all negative. Six children presented with acute or chronic hepatitis B, another 5 children with acute hepatitis A. One blood test for cysticercosis was positive. Two children presented with malaria. 58% of the children carried an intestinal parasite; the most prevalent was Giardia duodenalis. Bacteriological stool culture was positive for 17 children, for 9 with an antibiotic resistant bacterium. Twenty-seven children had a positive virological stool culture, 2 for a poliovirus. CONCLUSION: A systematic infectious check-up should be performed for a child adopted internationally when he/she arrives in France. This allows diagnosing diseases requiring an emergency treatment, or asymptomatic but severe diseases when chronic. Some blood tests must be double-checked when the child arrives, because of possible false negative initial tests results in the country of origin. Screening, early treatment, and implementing prophylaxis can decrease the risk of transmission to relatives. It also allows monitoring the antimicrobial resistance of some pathogens and the reintroduction of the poliovirus in France.

Barrett's esophagus, esophageal and esophagogastric junction adenocarcinomas: the role of diet.

Identification of modifiable risk factors is an attractive approach to primary prevention of esophageal adenocarcinoma (EAC) and esophagogastric junction adenocarcinoma (EGJAC). We conducted a review of the literature to investigate the association between specific dietary components and the risk of Barrett's esophagus (BE), EAC and EGJAC, supposing diet might be a risk factor for these tumors. Consumption of meat and high-fat meals has been found positively associated with EAC and EGJAC. An inverse association with increased intake of fruit, vegetables and antioxidants has been reported but this association was not consistent across all studies reviewed. Few studies have examined the association between diet and BE. Additional research is needed to confirm the aforementioned association and clarify the mechanisms by which dietary components affect the risk of developing EAC and EGJAC. Future studies could advance our knowledge by emphasizing prospective designs to reduce recall bias, by using validated dietary intake questionnaires and biological measures and by considering important confounders such as gastro-esophageal reflux disease (GERD) symptoms, tobacco and alcohol use, biometrics, physical activity, and socioeconomic factors.

Human tibia bone marrow blood perfusion by non-invasive near infrared spectroscopy: a new tool for studies on microgravity.

Human tibia bone marrow (BM) and tibialis anterior muscle (TA) perfusion index (PI) was assessed non-invasively by near infrared spectroscopy. A decrease in the postis-chaemic reperfusion capability of the human tibia BM and TA muscle was observed for increasing age i.e., PI increases linearly as a function of age, starting from 30 years, both for BM (0.062 %/year, from -4.185 to -0.967 %/s) and TA muscle (0.046 %/year, from -5.760 to -3.883 %/s). The results define a "normal" baseline and demonstrate the sensitivity of the method to PI changes. The present technique should allow one to investigate physio-pathological effects induced by microgravity on tibia BM blood perfusion.

The induction of distinct cytokine cascades correlates with different effects of granulocyte-colony stimulating factor and granulocyte/macrophage-colony-stimulating factor on the lymphocyte compartment in the course of high-dose chemotherapy for breast cancer.

The availability of the myeloid hemopoietic growth factors (HGF) granulocyte- and granulocyte/macrophage-colony stimulating factor (G-CSF and GM-CSF) has enhanced the therapeutic index of high-dose chemotherapeutic antitumoral regimens (HDCT), as well as the rate of severe damage to immune competence. We investigated some immune functions before, during and after one course of HDCT for poor-risk breast cancer and compared the effects of G-CSF and GM-CSF on the immune recovery. They exerted different influences on the functions we examined and showed distinctive patterns of both qualitative and quantitative in vivo activities on the immune system. The main findings were that (a) granulocyte and lymphocyte recovery rates were faster in the patients receiving G-CSF; (b) looking at the lymphocyte compartment, this difference was restricted to the CD3(+)/CD8(+) and CD56(+) lymphocyte subsets; (c) the reconstitution rate of CD19(+) lymphocytes was slow in both groups; (d) at the end of follow-up HLA-DR expression by CD3(+) lymphocytes was higher in the GM-CSF group; (e) the lymphocyte proliferative capacity was restored at a faster rate in the GM-CSF group, whereas cytotoxic activities recovered better in the G-CSF group; (f) the early repopulating phase was characterized by higher interleukin-6 serum levels in the GM-CSF group. Overall, GM-CSF seemed to exert an earlier effect on all T lymphocyte subsets, preventing them from a complete drop during the long-lasting "nadir" of the cell count, whereas G-CSF appeared to boost them strongly, though a few days later, hastening their final recovery. The distinct pattern of the cytokine cascade induced by each factor, consistent with the different functional changes, seemed to account for the peculiarities of their immune modulations.
