RESUMO

Background and Objectives: The surgical choice treatment of the breast cancer mostly depends on the stage of the disease. In the last years, breast cancer surgery has moved from being destructive to being more respectful of the anatomical and physiological integrity of the gland. The aim of the breast surgery should be finalized to obtain the best aesthetic and functional results, respecting the principles of oncologic radicality. The present study is a retrospective analysis aimed to evaluate the long-term outcomes of a conservative technique like the nipple-sparing mastectomy. Materials and Methods: We observed 894 patients with a median age of 47.5 years old, underwent nipple-sparing mastectomy between 2002-2017. The data acquired include population and tumor characteristics, patient reconstructive outcomes, including locoregional, regional, and distant metastases; other variables, among nipple-areola complex necrosis and infection were collected. Results: The complications detected were considered as "early" within 1 month later the nipple-sparing mastectomy or "late" after this time. The overall complications rate (early and late) and the overall survival and the relapses detected by this study were comparable with those reported in the literature. In order to identify factors that correlate with complications, either early or later, it has been processed an evaluation of the univariate analysis showing adjuvant chemotherapy as the only predictive factor for late complications, while we encountered no predictors for early complications. Conclusions: The present study adds to the data already present in literature, demonstrating that the nipple-sparing mastectomy is a safe procedure, providing good oncological and aesthetic results in patients carefully selected.

RESUMO

INTRODUCTION: Although the prevalence of celiac disease (CD) has been extensively investigated in recent years, an accurate estimate of CD frequency in the European population is still lacking. The aims of this study were: 1) to establish accurately the prevalence of CD in a large sample of the European population (Finland, Germany, Italy, and UK), including both children and adults; and 2) to investigate whether the prevalence of CD significantly varies between different areas of the European continent. MATERIALS AND METHODS: Samples were drawn from the four populations. All 29,212 participants were tested for CD by tissue transglutaminase (tTG) antibody test. Positive and border-line findings were further tested for serum endomysial antibodies (EMA). All serological determinations were centrally performed. Small-bowel biopsies were recommended to autoantibody-positive individuals. Previously diagnosed cases were identified. RESULTS: The overall CD prevalence (previously diagnosed plus anti-tTG and EMA positives) was 1.0% (95% CI 0.9-1.1). In subjects aged 30-64 years CD prevalence was 2.4% in Finland (2.0-2.8), 0.3% in Germany (0.1-0.4), and 0.7% in Italy (0.4-1.0). Sixty-eight percent of antibody-positive individuals showed small-bowel mucosal changes typical for CD (Marsh II/III lesion). CONCLUSIONS: CD is common in Europe. CD prevalence shows large unexplained differences in adult age across different European countries.

RESUMO

BACKGROUND: Treatment of celiac disease (CD) is based on the avoidance of gluten-containing food. However, it is not known whether trace amounts of gluten are harmful to treated patients. OBJECTIVE: The objective was to establish the safety threshold of prolonged exposure to trace amounts of gluten (ie, contaminating gluten). DESIGN: This was a multicenter, double-blind, placebo-controlled, randomized trial in 49 adults with biopsy-proven CD who were being treated with a gluten-free diet (GFD) for > or =2 y. The background daily gluten intake was maintained at < 5 mg. After a baseline evaluation (t0), patients were assigned to ingest daily for 90 d a capsule containing 0, 10, or 50 mg gluten. Clinical, serologic, and histologic evaluations of the small intestine were performed at t0 and after the gluten microchallenge (t1). RESULTS: At t0, the median villous height/crypt depth (Vh/Cd) in the small-intestinal mucosa was significantly lower and the intraepithelial lymphocyte (IEL) count (x 100 enterocytes) significantly higher in the CD patients (Vh/Cd: 2.20; 95% CI: 2.11, 2.89; IEL: 27; 95% CI: 23, 34) than in 20 non-CD control subjects (Vh/Cd: 2.87; 95% CI: 2.50, 3.09; IEL: 22; 95% CI: 18, 24). One patient (challenged with 10 mg gluten) developed a clinical relapse. At t(1), the percentage change in Vh/Cd was 9% (95% CI: 3%, 15%) in the placebo group (n = 13), -1% (-18%, 68%) in the 10-mg group (n = 13), and -20% (-22%, -13%) in the 50-mg group (n = 13). No significant differences in the IEL count were found between the 3 groups. CONCLUSIONS: The ingestion of contaminating gluten should be kept lower than 50 mg/d in the treatment of CD.

RESUMO

INTRODUCTION: Coeliac disease (CD) is associated with an increased risk of non-Hodgkin lymphoma (NHL), but there is little information about whether this is true for clinically silent CD. OBJECTIVE: To investigate the frequency of CD in two European populations; one with NHL and another derived from the general population. METHODS: A prospective, multi-centre, case-control study in 10 European countries was conducted between May 1998 and April 2001. A total of 1446 consecutive patients with newly diagnosed NHL aged over 18 years was collected. The control group consisted of a population of 9676 individuals who were screened for CD. The number of patients with a previous diagnosis of CD and those with silent CD detected by screening were determined in the two groups. RESULTS: The patients with CD had a significantly increased risk of developing NHL [odds ratio (OR) 2.6, 95% confidence interval (CI) 1.4-4.9]. This risk was only present in patients with CD diagnosed clinically before the study (OR 3.3, 95% CI 1.4-7.9), but not in those with silent CD detected by screening (OR 1.3, 95% CI 0.6-2.7). CONCLUSION: Patients with CD have an increased risk of developing NHL, although this is lower than previously thought. Clinically silent CD is rare in patients with NHL.

RESUMO

OBJECTIVE: To investigate the value of serum antitissue transglutaminase IgA antibodies (IgA-TTG) and IgA antiendomysial antibodies (IgA-EMA) in the diagnosis of coeliac disease in cohorts from different geographical areas in Europe. The setting allowed a further comparison between the antibody results and the conventional small-intestinal histology. METHODS: A total of 144 cases with coeliac disease [median age 19.5 years (range 0.9-81.4)], and 127 disease controls [median age 29.2 years (range 0.5-79.0)], were recruited, on the basis of biopsy, from 13 centres in nine countries. All biopsy specimens were re-evaluated and classified blindly a second time by two investigators. IgA-TTG were determined by ELISA with human recombinant antigen and IgA-EMA by an immunofluorescence test with human umbilical cord as antigen. RESULTS: The quality of the biopsy specimens was not acceptable in 29 (10.7%) of 271 cases and a reliable judgement could not be made, mainly due to poor orientation of the samples. The primary clinical diagnosis and the second classification of the biopsy specimens were divergent in nine cases, and one patient was initially enrolled in the wrong group. Thus, 126 coeliac patients and 106 controls, verified by biopsy, remained for final analysis. The sensitivity of IgA-TTG was 94% and IgA-EMA 89%, the specificity was 99% and 98%, respectively. CONCLUSIONS: Serum IgA-TTG measurement is effective and at least as good as IgA-EMA in the identification of coeliac disease. Due to a high percentage of poor histological specimens, the diagnosis of coeliac disease should not depend only on biopsy, but in addition the clinical picture and serology should be considered.

RESUMO

CONTEXT: Celiac disease is one of the most common lifelong disorders. Non-Hodgkin lymphoma is a possible complication of celiac disease and may lead to a large portion of lymphoma cases. OBJECTIVE: To quantify the risk for developing non-Hodgkin lymphoma of any primary site associated with celiac disease. DESIGN AND SETTING: Multicenter, case-control study conducted between January 1996 and December 1999 throughout Italy. PATIENTS: Cases were older than 20 years (median, 57; range, 20-92 years) with non-Hodgkin lymphoma of any primary site and histological type and were recruited at the time of the diagnosis. Controls were healthy adults (2739 men and 2981 women) from the general population. MAIN OUTCOME MEASURE: Positive test result for class A serum antiendomysial antibody. RESULTS: Celiac disease was diagnosed in 6 (0.92%) of 653 patients with lymphoma. Of the 6 cases, 3 were of B-cell and 3 were of T-cell origin. Four of 6 cases had lymphoma primarily located in the gut. In the control group, 24 (0.42%) had celiac disease. The odds ratio (adjusted for age and sex) for non-Hodgkin lymphoma of any primary site associated with celiac disease was 3.1 (95% confidence interval [CI], 1.3-7.6), 16.9 (95% CI, 7.4-38.7) for gut lymphoma, and 19.2 (95% CI, 7.9-46.6) for T-cell lymphoma, respectively. The risk for non-Hodgkin lymphoma for the overall population, which was adjusted for age and sex, was 0.63% (95% CI, - 0.12% to 1.37%). CONCLUSION: Celiac disease is associated with an increased risk for non-Hodgkin lymphoma, especially of T-cell type and primarily localized in the gut. However, the association does not represent a great enough risk to justify early mass screening for celiac disease.
