RESUMEN
INTRODUCTION: Chronic atrophic gastritis may contribute to gastric polyps (GP) phenotype in familial adenomatous polyposis (FAP). Considering the high prevalence of Helicobacter-pylori (HP) infection in Portugal, we aim to characterise GP in a series of Portuguese patients. METHODS: In a retrospectively-selected series of 53 FAP patients, clinical data and histopathological features of GP and background gastric mucosa were studied. SPSS (27.0) was used for statistical analysis. RESULTS: Thirteen patients (24.5%) developed fundic gland polyps (FGP), seven (13.2%) gastric adenomas (GA) and ten (18.9%) both FGP and GA. Out of 100 GP, four were hyperplastic polyps, 58 FGP (24 with dysplasia), 35 intestinal-type GA (intGA) and three foveolar-type GA (fovGA). IntGA were larger (60% >7mm, p=0.03), occurred predominantly in the distal stomach (66.7%, p=0.024), in patients harbouring gastric intestinal metaplasia (IM) (86.7%, p<0.001) and duodenal adenomas (86.7%, p<0.001) Conclusion: This is the first Western series showing high prevalence of intGA in FAP patients, comparable to Asian cohorts. HP infection and chronic atrophic gastritis/intestinal metaplasia are likely responsible for this difference, with risk of neoplastic transformation and management implications. Biopsy/excision of GP >7mm, in the distal stomach, and in patients harbouring gastric intestinal metaplasia/duodenal adenomas should be considered.
RESUMEN
BACKGROUND AND AIM: Stroke is a major health problem. Several studies reported sex differences regarding stroke. We aim to study this issue in an incidence stroke study. METHODS: Data were retrieved from a community-based prospective register of patients that had a first ever stroke in a life time between October 2009 and September 2011. We studied sex differences regarding demographic data, vascular risk factors, stroke type, stroke severity (NIHSS), disability at 28days (modified Rankin scale (mRS)), and case fatality at 30 and 90days. RESULTS: From 720 stroke patients, 45.3% were men. Women were older (75.0 ± 13.6 versus 67.2 ± 14.9 years), had a worse premorbid mRS (39.3% versus 25.5%, P < .001), and a higher prevalence of hypertension (Pâ¯=â¯.004) and atrial fibrillation (P < .001). Previous myocardial infarction was more frequent in men (Pâ¯=â¯.001), as well as smoking habits (P < .001). Ischemic stroke was more common in women than men (87.6% versus 81.3%, Pâ¯=â¯.038). The 28 days' outcome was worse in women (mRS ≥ 2, 77.2% versus 70.6%, Pâ¯=â¯.044). No differences were found in initial stroke severity (median NIHSSâ¯=â¯4) and case fatality at 30 and 90days, after adjusting for age and premorbid mRS. CONCLUSION: No differences were found in stroke initial severity and mortality at 30 and 90days between men and women, despite the sex differences pertaining to the stroke profile-age, vascular risk factors, stroke type, and outcome. Our results are somewhat discrepant from those described in the literature; more research is needed to understand if this may be due to changes in stroke standard of care.

Kimura's disease (KD) was first described in 1937. It is a rare, benign, and chronic immune-mediated inflammatory disorder affecting the subcutaneous tissue, salivary glands, and lymph nodes. The disease is more common in the second to third decades of life in middle-aged Southeast Asian countries. The cause of Kimura's disease remains unknown; some authors believe it is related to an autoimmune or delayed-type hypersensitivity reaction. It commonly presents as a solitary painless lymph node in the head and neck or generalized lymphadenopathy (67%-100%) associated with peripheral eosinophilia and elevated IgE levels. Renal involvement may occur in some patients. Diagnosis is made by histology. A 21-year-old Caucasian man with no relevant medical history presented with a non-tender swelling of the left hemiface without other associated symptoms. Laboratory investigations revealed a leukocyte count with eosinophilia (2.29×10^9/L- 26.5%) and elevated total IgE and IgG4. He had no renal dysfunction. He underwent surgical resection of the lesion in the jugal, infraorbital, and left nasolabial regions, and the anatomopathological examination revealed the characteristics of Kimura's disease. Three months after surgery, an MRI showed an increase in the size of the mass, and he was started on corticosteroids. Six months after surgery, he presented with a slight increase in the size of the mass and was started on Ciclosporin, which allowed a progressive reduction in the dose of corticosteroid with evidence of a progressive reduction in swelling. Ciclosporin was stopped due to toxic serum levels, and he was started on mycophenolate mofetil. The dose was increased because of the increase in facial mass; on mycophenolate mofetil 2500mg/day, the patient remains stable. KD is a chronic disorder of unknown etiology that mainly affects young people in Southeast Asia and is rare in Western countries, as in the case of this young man. Studies have shown no significant differences in region or race, complications, multiplicity, laterality, anatomical distribution, maximum size, eosinophil count, or IgE levels between age groups. There is no consensus on the optimal treatment for KD; several treatments have been used, including surgery, systemic corticosteroids, immunosuppressants, and radiation. Due to the tendency to relapse and the rarity of the disease, there is no consensus on treatment options for relapse.
RESUMEN
Background: Hospitalization and readmission rates after a first-ever-in-a-lifetime stroke (FELS) are considered measures of quality of care and, importantly, may give valuable information to better allocate health-related resources. We aimed to investigate the hospitalization pattern and the unplanned readmissions or death of hospitalized (HospS) and non-hospitalized stroke (NHospS) patients 1 year after a FELS, based on a community register. Methods: Data about hospitalization and unplanned readmissions and case fatality 1 year after a FELS were retrieved from the population-based register undertaken in Northern Portugal (ACIN2), comprising all FELS in 2009-2011. We used the Kaplan-Meier method to estimate 1-year readmission/death-free survival and Cox proportional hazard models to identify independent factors for readmission/death. Results: Of the 720 FELS, 35.7% were not hospitalized. Unplanned readmission/death within 1 year occurred in 33.0 and 24.9% of HospS and NHospS patients, respectively. The leading causes of readmission were infections, recurrent stroke, and cardiovascular events. Stroke-related readmissions were observed in more than half of the patients in both groups. Male sex, age, pre- and post-stroke functional status, and diabetes were independent factors of readmission/death within 1 year. Conclusion: About one-third of stroke patients were not hospitalized, and the readmission/death rate was higher in HospS patients. Still, that readmission/death rate difference was likely due to other factors than hospitalization itself. Our research provides novel information that may help implement targeted health-related policies to reduce the burden of stroke and its complications.
RESUMEN
Background: After a first-ever-in-a-lifetime stroke (FELS), hospital readmissions are common and associated with increased mortality and morbidity of stroke survivors, thus, raising the overall health burden of stroke. Population-based stroke studies on hospital readmissions are scarce despite it being an important healthcare service quality indicator. We evaluated unplanned readmissions or death during the first year after a FELS and their potential factors, based on a Portuguese community register. Methods: Data were retrieved from a population-based prospective register undertaken in Northern Portugal (ACIN2) in 2009-2011. Retrospective information about unplanned hospital readmissions and case fatality within 1 year after FELS index hospitalization (FELS-IH) was evaluated. Readmission/death-free survival 1 year after discharge was estimated using the Kaplan-Meyer method. Independent risk factors for readmission/death were identified using Cox proportional hazard models. Results: Unplanned readmission/death within 1 year occurred in 120 (31.6%) of the 389 hospitalized FELS survivors. In 31.2% and 33.5% of the cases, it occurred after ischemic stroke or intracerebral hemorrhage, respectively. Infections and cerebrovascular and cardiovascular diseases were the main causes of readmission. Of the readmissions, 65.3% and 52.5% were potentially avoidable or stroke related, respectively. The main cause of potentially avoidable readmissions was the continuation/recurrence of the event responsible for the initial admission or a closely related condition (71.2%). Male sex, age, previous and post-stroke functional status, and FELS-IH length of stay were independent factors of readmission/death within 1 year. Conclusions: Almost one-third of FELS survivors were readmitted/dead 1 year after their FELS-IH. This outcome persisted after the first months after stroke hospitalization in all stroke subtypes. More than half of readmissions were considered potentially avoidable or stroke related.
