Epidemiology and prognosis of synchronous and metachronous colon cancer metastases: a French population-based study.
2014
Epidemiological data on synchronous and metachronous metastatic colon cancer are scarce. We assessed epidemiological characteristics and survival in synchronous and metachronous metastatic colon cancer in a French population.Our study included 932 cases of metastatic colon cancer diagnosed in 1999-2010 and registered in a population-based cancer registry; 758 were synchronous colon metastases and 174 metachronous metastases from resected primary colon cancers diagnosed in 1999-2005. Univariate relative survival was calculated and a multivariate model with proportional hazard applied to net survival by interval was used.Mean age at diagnosis was 71.1 years for patients with metachronous meta…
Application of a new classification to a breast tumor series from a population-based cancer registry: demographic, clinical, and prognostic features …
2009
A new classification based on gene expression profiling or immunohistochemical (IHC) characteristics may replace current histopathological classifications and predict better clinical outcomes. We used IHC markers to classify incident cases ascertained by the Palermo Breast Cancer Registry (2002-2004) into four subtypes: luminal-A (ER+ or PgR+ and HER2/neu-); luminal-B (ER+ or PgR+, HER2/neu+); basal-like (ER-, PgR-, HER2/neu-); and HER2+/ER- (HER2/neu+, ER-, PgR-). We evaluated HER2/neu, ER and PgR in 1300/1985 (65%) cases. The most common IHC-subtype was luminal-A (68%), whereas luminal-B, basal-like, and HER2+/ER- accounted for 14%, 13%, and 5%, respectively. IHC-subtypes were not associa…
Definition and management of colorectal polyposis not associated with APC/MUTYH germline pathogenic variants: AIFEG consensus statement
2021
An expert consensus panel convened by the Italian Association for Inherited and Familial Gastrointestinal Tumors (Associazione Italiana per lo Studio della Familiarita ed Ereditarieta dei Tumori Gastrointestinali, AIFEG) reviewed the literature and agreed on a number of position statements regarding the definition and management of polyposis coli without an identified pathogenic mutation on the APC or MUTYH genes, defined in the document as NAMP (non-APC/MUTYH polyposis).
ADVANCED ENDOSCOPIC IMAGING FOR SURVEILLANCE FOR DYSPLASIA AND COLORECTAL CANCER IN INFLAMMATORY BOWEL DISEASE: COULD THE PATHOLOGIST BE FURTHER HELP…
2014
Patients with inflammatory bowel disease (IBD) have an increased risk of developing intestinal cancer. The magnitude of that increased risk as well as how best to mitigate it remain a topic of ongoing investigation in the field. It is important to quantify the risk of colorectal cancer in association with IBD. The reported risk varies widely between studies. This is partly due to the different methodologies used in the studies. Because of the limitations of surveillance strategies based on the detection of dysplasia, advanced endoscopic imaging and techniques involving the detection of alterations in mucosal antigens and genetic abnormalities are being investigated. Development of new bioma…
The association between respiratory tract infection incidence and localised meningitis epidemics: an analysis of high-resolution surveillance data fr…
2017
AbstractMeningococcal meningitis epidemics in the African meningitis belt consist of localised meningitis epidemics (LME) that reach attack proportions of 1% within a few weeks. A meningococcal serogroup A conjugate vaccine was introduced in meningitis belt countries from 2010 on, but LME due to other serogroups continue to occur. The mechanisms underlying LME are poorly understood, but an association with respiratory pathogens has been hypothesised. We analysed national routine surveillance data in high spatial resolution (health centre level) from 13 districts in Burkina Faso, 2004–2014. We defined LME as a weekly incidence rate of suspected meningitis ≥75 per 100,000 during ≥2 weeks; and…
Alteraciones del comportamiento. Prevalencia en las consultas de pediatría de atención primaria: Comunidad Valenciana, 2009
2012
Background: Childhood and adolescence mental health needs a proper monitoring. The aim is to estimate behavioral disorders preva- lence in paediatric primary care in the Region of Valencia (Spain) and to describe its distribution according to sex, age and impact areas. Methods: Cross-sectional research. Region of Valencia’s Health Surveillance Network observed along 2009 the behavioral disorders in patients primary health care between 3 and 14 years old. Prevalence and confidence intervals at 95% were calculated. Chi-square test (p<0,05) was calculated to explore the differences in behavioral disorders accor- ding to sex, age and impact areas. Results: Total cases notified were 626. Out of …
Differential diagnosis of illness in patients under investigation for the novel coronavirus (SARS-CoV-2), Italy, February 2020
2020
A novel coronavirus (SARS-CoV-2) has been identified as the causative pathogen of an ongoing outbreak of respiratory disease, now named COVID-19. Most cases and sustained transmission occurred in China, but travel-associated cases have been reported in other countries, including Europe and Italy. Since the symptoms are similar to other respiratory infections, differential diagnosis in travellers arriving from countries with wide-spread COVID-19 must include other more common infections such as influenza and other respiratory tract diseases.
Candida SPP. Colonization in NICU: A 2-Year Surveillance Study
2016
Introduction: Fungal infections are an important cause of increased morbidity and mortality in infants admitted to neonatal intensive care units (NICUs). In VLBW infants, Candida (C.) albicans is the third most common cause of neonatal late onset sepsis (LOS). The overall incidence of candidemia in NICU is increasing because of the longer survival and the invasive procedures related with the intensive care of extremely preterm infants. Prevention of candidemia in neonates is supported by the identification and adequate management of specific risk factors, including low birth weight, use of invasive devices, prolonged hospitalization and use of broad-spectrum antimicrobial agents. Effective …
Identification of pH-regulated antigen 1 released from Candida albicans as the major ligand for leukocyte integrin alphaMbeta2.
2007
Candida albicans is a common opportunistic fungal pathogen and is the leading cause of invasive fungal disease in immunocompromised individuals. The induction of cell-mediated immunity to C. albicans is of critical importance in host defense and the prime task of cells of the innate immune system. We previously demonstrated that the integrin alpha(M)beta(2) (CD11b/CD18) is the major leukocyte receptor involved in C. albicans recognition, mediating both adhesive and migratory responses to the fungus. In the present study, we demonstrate that various C. albicans strains release a protease-sensitive activity into their conditioned medium that supports alpha(M)beta(2)-mediated cell adhesion and…
Adverse Reactions to Anti-SARS-CoV-2 Vaccine: A Prospective Cohort Study Based on an Active Surveillance System
2022
To date, Coronavirus disease (COVID-19) has caused high morbidity and mortality worldwide. To counteract the pandemic scenario, several vaccines against the etiological factor of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) were developed and tested. At the end of December 2020, BNT162b2 (Comirnaty, Pfizer-BioNTech) was the first and only authorized vaccine in Italy for selected categories, such as healthcare workers, fragile patients and people aged over 80 years old. To master our knowledge about BNT162b2 adverse reactions (ARs), an active surveillance system based on instant messaging was realized for voluntary participants who had been vaccinated at COVID-19 Vaccination …
