Upper gastrointestinal bleeding related to migraine: the importance of education for migraine care
Physicians involved in care of migraine patients should make a considerable effort to educate themselves and their patients. It is fundamental that doctors, patients and their families understand the causes of migraine, and know the different treatment strategies available to improve migraine care. Mallory-Weiss tears are lacerations in the region of the cardioesophageal junction due to vomiting. We report a case of Mallory-Weiss tear secondary to migraine that could had been reasonably avoided had the patient been treated with triptans since the first attack, according to the stratified care strategy. This case illustrates that inadequate management can cause serious medical consequences. It also proves that it is necessary to improve education about migraine for both patients and doctors
Esófago de Barrett
El esófago de Barrett (EB) es una complicación de la enfermedad por reflujo gastroesofágico consistente en la sustitución del epitelio escamoso por epitelio columnar metaplásico. Otros
agentes lesivos, como los ácidos biliares, pueden favorecer su aparición. Es una lesión
premaligna, que puede evolucionar a adenocar
cinoma. Este tumor ocasiona síntomas tardíos, lo que obliga a un seguimiento endoscópico con múltiples biopsias, para detectar el grado de displasia o el adenocarcinoma en estadíos susceptibles de tratamiento eficaz.
Dada la alta prevalencia de EB, el coste de los programas de vigilancia es alto y su seguimiento difícil. Actualmente dos objetivos son prioritarios: 1) Definir factores predictivos de evolución a
displasia-carcinoma, que obligan a un seguimiento estrecho. 2) Conseguir la remisión completa o impedir la progresión a adenocarcinoma. Ninguno de los tratamientos actualmente aceptados ha demostrado efectividad inequívoca. Recientemente se han desarrollado nuevas técnicas endoscópicas con resultados preliminares prometedores, que requieren confirmación en series

Gastroduodenal injury after radioembolization of hepatic tumors
Radioembolization is a new tool for the treatment of hepatic tumors
that consists in the injection of biocompatible microspheres carrying
radioisotopes into the hepatic artery or its branches. METHODS: We have performed
radioembolization in 78 patients with hepatic tumors using resin-based
microspheres loaded with yttrium-90. All patients were previously evaluated to
minimize the risk of hazardous irradiation to nontarget organs and to obtain the
data needed for dose calculation. RESULTS: We report a complication found in
three cases (3.8%) that consists of abdominal pain resulting from gastroduodenal
lesions and that had a chronic, insidious course. Microscopically, microspheres
were detected in the specimens obtained from all affected gastric areas. Since
these gastroduodenal lesions do not appear when nonradiating microspheres are
injected in animals, lesions are likely to be due to radiation and not to an
ischemic effect of vascular occlusion by spheres. CONCLUSIONS: We believe that a
pretreatment evaluation that includes a more thorough scrutiny of the hepatic
vascularization in search of small collaterals connecting to the gastroduodenal
tract can help prevent this awkward complicatio
Use of colonoscopy as a primary screening test for colorectal cancer in average risk people
The use of colonoscopy as a primary screening test for colorectal
cancer (CRC) in average risk adults is a subject of controversy. Our primary
objective was to build a predictive model based on a few simple variables that
could be used as a guide for identifying average risk adults more suitable for
examination with colonoscopy as a primary screening test. METHODS: The prevalence
of advanced adenomas was assessed by primary screening colonoscopy in 2210
consecutive adults at least 40 yr old, without known risk factors for CRC. Age,
gender, and clinical and biochemical data were compared among people without
adenomas, those with non-advanced adenomas, and those with any advanced neoplasm.
A combined score to assess the risk of advanced adenomas was built with the
variables selected by multiple logistic regression analysis. RESULTS: Neoplastic
lesions were found in 617 subjects (27.9%), including 259 with at least one
neoplasm that was 10 mm or larger, villous, or with moderate-to-severe dysplasia,
and 11 with invasive cancers. Advanced lesions were more frequent among men,
older people, and those with a higher body mass index (BMI). These three
variables were independent predictors of advanced adenomas in multivariate
analysis. A score combining age, sex, and BMI was developed as a guide for
identifying individuals more suitable for screening colonoscopy. CONCLUSIONS:
Age, gender, and BMI can be used to build a simple score to select those average
risk adults who might be candidates for primary screening colonoscop
Diagnostic value of distal colonic polyps for prediction of advanced proximal neoplasia in an average-risk population undergoing screening colonoscopy
For colorectal cancer screening, the predictive value of distal
findings in the ascertainment of proximal lesions is not fully established. The
aims of this study were to assess distal findings as predictors of advanced
proximal neoplasia and to compare the predictive value of endoscopy alone vs.
combined endoscopic and histopathologic data. METHODS: Primary colonoscopy
screening was performed in 2210 consecutive, average-risk adults. Age, gender,
endoscopic (size, number of polyps), and histopathologic distal findings were
used as potential predictors of advanced proximal neoplasms (i.e., any adenoma >
or =1 cm in size, and/or with villous histology, and/or with severe dysplasia or
invasive cancer). Polyps were defined as distal if located in the descending
colon, the sigmoid colon, or the rectum. Those in other locations were designated
proximal. RESULTS: Neoplastic lesions, including 11 invasive cancers, were found
in 617 (27.9%) patients. Advanced proximal neoplasms without any distal adenoma
were present in 1.3% of patients. Of the advanced proximal lesions, 39% were not
associated with any distal polyp. Older age, male gender, and distal adenoma were
independent predictors of advanced proximal neoplasms. The predictive ability of
a model with endoscopic data alone did not improve after inclusion of
histopathologic data. In multivariate logistic regression analysis, the
predictive ability of models that use age, gender, and any combination of distal
findings was relatively low. The proportion of advanced proximal neoplasms
identified if any distal polyp was an indication for colonoscopy was only 62%.
CONCLUSIONS: A strategy in which colonoscopy is performed solely in patients with
distal colonic findings is not effective screening for the detection of advanced
proximal neoplasms in an average-risk populatio
EoE CONNECT, the European Registry of Clinical, Environmental, and Genetic Determinants in Eosinophilic Esophagitis:rationale, design, and study protocol of a large-scale epidemiological study in Europe
BACKGROUND: The growing prevalence of eosinophilic esophagitis (EoE) represents a considerable burden to patients and health care systems. Optimizing cost-effective management and identifying mechanisms for disease onset and progression are required. However, the paucity of large patient cohorts and heterogeneity of practice hinder the defining of optimal management of EoE. METHODS: EoE CONNECT is an ongoing, prospective registry study initiated in 2016 and currently managed by EUREOS, the European Consortium for Eosinophilic Diseases of the Gastrointestinal Tract. Patients are managed and treated by their responsible specialists independently. Data recorded using a web-based system include demographic and clinical variables; patient allergies; environmental, intrapartum, and early life exposures; and family background. Symptoms are structurally assessed at every visit; endoscopic features and histological findings are recorded for each examination. Prospective treatment data are registered sequentially, with new sequences created each time a different treatment (active principle, formulation, or dose) is administered to a patient. EoE CONNECT database is actively monitored to ensure the highest data accuracy and the highest scientific and ethical standards. RESULTS: EoE CONNECT is currently being conducted at 39 centers in Europe and enrolls patients of all ages with EoE. In its aim to increase knowledge, to date EoE CONNECT has provided evidence on the effectiveness of first- and second-line therapies for EoE in clinical practice, the ability of proton pump inhibitors to induce disease remission, and factors associated with improved response. Drug effects to reverse fibrous remodeling and endoscopic features of fibrosis in EoE have also been assessed. CONCLUSION: This prospective registry study will provide important information on the epidemiological and clinical aspects of EoE and evidence as to the real-world and long-term effectiveness and safety of therapy. These data will potentially be a vital benchmark for planning future EoE health care services in Europe
Development of a framework for fire risk assessment using remote sensing and geographic information system technologies
Forest fires play a critical role in landscape transformation, vegetation succession, soil degradation and air quality. Improvements in fire risk estimation are vital to reduce the negative impacts of fire, either by lessen burn severity or intensity through fuel management, or by aiding the natural vegetation recovery using post-fire treatments. This paper presents the methods to generate the input variables and the risk integration developed within the Firemap project (funded under the Spanish Ministry of Science and Technology) to map wildland fire risk for several regions of Spain. After defining the conceptual scheme for fire risk assessment, the paper describes the methods used to generate the risk parameters, and presents proposals for their integration into synthetic risk indices. The generation of the input variables was based on an extensive use of geographic information system and remote sensing technologies, since the project was intended to provide a spatial and temporal assessment of risk conditions. All variables were mapped at 1 km2 spatial resolution, and were integrated into a web-mapping service system. This service was active in the summer of 2007 for semi-operational testing of end-users. The paper also presents the first validation results of the danger index, by comparing temporal trends of different danger components and fire occurrence in the different study regions.The Firemap project was funded by the Spanish Ministry of Science and Education (CGL2004-060490C04-01/CLI) through the Environment and Climate programPeer reviewe
Accurate and timely diagnosis of Eosinophilic Esophagitis improves over time in Europe. An analysis of the EoE CONNECT Registry
BACKGROUND: Poor adherence to clinical practice guidelines for eosinophilic esophagitis (EoE) has been described and the diagnostic delay of the disease continues to be unacceptable in many settings. OBJECTIVE: To analyze the impact of improved knowledge provided by the successive international clinical practice guidelines on reducing diagnostic delay and improving the diagnostic process for European patients with EoE. METHODS: Cross‐sectional analysis of the EoE CONNECT registry based on clinical practice. Time periods defined by the publication dates of four major sets of guidelines over 10 years were considered. Patients were grouped per time period according to date of symptom onset. RESULTS: Data from 1,132 patients was analyzed and median (IQR) diagnostic delay in the whole series was 2.1 (0.7‐6.2) years. This gradually decreased over time with subsequent release of new guidelines (p < 0.001), from 12.7 years up to 2007 to 0.7 years after 2017. The proportion of patients with stricturing of mixed phenotypes at the point of EoE diagnosis also decreased over time (41.3% vs. 16%; p < 0.001), as did EREFS scores. The fibrotic sub‐score decreased from a median (IQR) of 2 (1‐2) to 0 (0‐1) when patients whose symptoms started up to 2007 and after 2017 were compared (p < 0.001). In parallel, symptoms measured with the Dysphagia Symptoms Score reduced significantly when patients with symptoms starting before 2007 and after 2012 were compared. A reduction in the number of endoscopies patients underwent before the one that achieved an EoE diagnosis, and the use of allergy testing as part of the diagnostic workout of EoE, also reduced significantly over time (p = 0.010 and p < 0.001, respectively). CONCLUSION: The diagnostic work‐up of EoE patients improved substantially over time at the European sites contributing to EoE CONNECT, with a dramatic reduction in diagnostic delay
