BackgroundCastanea sativa pollen allergy has generally been considered to be uncommon and clinically insignificant. In our geographical area (Plasencia, Cáceres, Spain) Castanea sativa pollen is a major pollen.ObjectiveTo determine the atmospheric fluctuations and prevalence of patients sensitized to Castanea pollen in our region and to compare this sensitization with sensitizations to other pollens.MethodsPatients with respiratory symptoms attending our outpatient clinic for the first time in 2003 were studied. The patients underwent skin prick tests with commercial extracts of a battery of inhalants including Castanea sativa pollen. Serologic specific IgE to Castanea sativa pollen was determined using the CAP system (Pharmacia &; Upjohn, Uppsala, Sweden). Airborne pollen counts in our city were obtained using Cour collection apparatus over a 4-year period (2000 to 2003).ResultsThe most predominant pollens detected were (mean of the maximal weekly concentrations over 4 years in pollen grains/m3): Quercus 968, Poacea 660, Olea 325, Platanus 229, Pinus 126, Cupresaceae 117, Plantago 109, Alnus 41, Populus 40, Castanea 32. We studied 346 patients (mean age: 24.1 years). In 210 patients with a diagnosis of pollinosis, the percentages of sensitization were: Dactylis glomerata 80.4%, Olea europea 71.9%, Fraxinus excelsior 68%, Plantago lanceolata 62.8%, Chenopodium album 60.9%, Robinia pseudoacacia 49 %, Artemisia vulgaris 43.8 %, Platanus acerifolia 36.6%, Parietaria judaica 36.1 %, Populus nigra 32.3%, Betula alba 27.6%, Quercus ilex 21.4%, Alnus glutinosa 20.9%, Cupressus arizonica 7.6% and Castanea sativa 7.1 %. Fifteen patients were sensitized to Castanea sativa and 14 had seasonal rhinoconjunctivitis and asthma. Ten patients had serum specific IgE to Castanea pollen (maximum value: 17.4 Ku/l). Castanea pollen is present in our area in large amounts from the 23rd to the 28th weeks of the year, with a peak pollen count in the 25th week.ConclusionsThe most important allergenic pollens in northern Extremadura were Poaceae, Olea europaea and Plantago sp. The prevalence of sensitization to Castanea sativa pollen was very low (7.1 %). Most sensitized patients had asthma and polysensitization. Castanea sativa pollen is not a major cause of pollinosis in our area. 相似文献

Background and objectiveDiabetes mellitus is the leading cause of chronic kidney disease (CKD) in our country. The objective was to estimate the global prevalence and by health areas of CKD in the diabetic population of Extremadura.Patients and methodsObservational, longitudinal retrospective study in the diabetic population attended in the Extremadura Health System in 2012–2014. A total of 90,709 patients ≥ 18 years old were studied. The estimated glomerular filtration rate (eGFR) was calculated using the Chronic Kidney Disease Epidemiology Collaboration equation (CKD-EPI). The presence of CKD was defined as follows: an eGFR<60 mL/min/1.73 m2 in a time period of greater than three months or the presence of renal damage, as evaluated by an urine albumin-creatinine ratio (UACR) ≥ 30 mg/g, with or without reduced eGFR, also in a time period of greater than three months.ResultsThe overall prevalence of CKD was 15.6% (17.5% in women and 13.7% in men) and it was higher in the province of Cáceres (17%) than in Badajoz (14.8%, p<0.001), with the lowest prevalence in the Navalmoral de la Mata health area (13%) and the highest in Plasencia (17.8%, p<0.001). The prevalence of CKD defined without the need for confirmation of the sustainability of kidney damage or decreased eGFR was 26.1% (29.3% in women and 22.9% in men), which represents an overestimation of the prevalence of 67%.ConclusionsThe prevalence of CKD in Extremadura's diabetic population is lower than usually referred to and differs significantly between its health areas. 相似文献

A total 89 fish and lamprey species has been recorded from Polish freshwater habitats. Twenty-seven of them (30.3%) have not been surveyed for parasitic helminthes. Some of the latter fishes are either rare or not easily accessible. Other live only in specific habitats in scattered localities. An important obstacle for studying parasite faunas of some fishes may be their status on an endangered species. Among the non-surveyed fishes, are those which have been relatively recently introduced to Poland or migrated there on their own. The present paper attempts to review all hitherto not studied helminthologically fish species, their habitats, localities and current protection status. 相似文献

根据传统的高血压水平的定义,1993年WHO高血压治疗指南提出血压控制目标为<140/90mm Hg(1mm Hg=0.133kPa),但是并非所有患者都必须将血压降至同一水平,而应根据患者情况进行个体化治疗。Framingham进行的一项长达10~12年的心血管事件研究发现,第5年后,正常上限血压[收缩压(SBP 相似文献

BACKGROUND AND AIM: Both the clinical presentation and the degree of mucosal damage in coeliac disease vary greatly. In view of conflicting information as to whether the mode of presentation correlates with the degree of villous atrophy, we reviewed a large cohort of patients with coeliac disease. PATIENTS AND METHODS: We correlated mode of presentation (classical, diarrhoea predominant or atypical/silent) with histology of duodenal biopsies and examined their trends over time. RESULTS: The cohort consisted of 499 adults, mean age 44.1 years, 68% females. The majority had silent coeliac disease (56%) and total villous atrophy (65%). There was no correlation of mode of presentation with the degree of villous atrophy (p=0.25). Sixty-eight percent of females and 58% of males had a severe villous atrophy (p=0.052). There was a significant trend over time for a greater proportion of patients presenting as atypical/silent coeliac disease and having partial villous atrophy, though the majority still had total villous atrophy. CONCLUSIONS: Among our patients the degree of villous atrophy in duodenal biopsies did not correlate with the mode of presentation, indicating that factors other than the degree of villous atrophy must account for diarrhoea in coeliac disease. 相似文献
