A pulmonary arteriovenous fistula is an abnormal connection between pulmonary arteries and veins. Patients with Rendu–Osler–Weber syndrome may present with this vascular malformation, which is a typical finding of the disease. Approximately 5–15% of Rendu–Osler–Weber syndrome patients have pulmonary arteriovenous malformations (AVM) and there is usually a family history of AVM in these patients. The malformations are usually located in the lower lobes. In this paper, I describe a 49‐year‐old male patient with dyspnoea, cough, haemoptysis and epistaxis. Physical examination showed nasal telangiectasias, cyanosis of the lips and nails, and a systolic bruit over the left lung. Chest X‐ray revealed a 5‐cm mass in the left lower lobe and after magnetic resonance examination, together with 3‐D magnetic resonance angiography, it was demonstrated to be a pulmonary arteriovenous fistula. The history of a niece with a similiar history of suspected pulmonary arteriovenous fistula led me to consider the possibility of Rendu–Osler–Weber syndrome presenting with a pulmonary arteriovenous fistula. 相似文献

The objective of this study was to assess the reproductive competence of oocytes obtained by follicular flushing in poor responder patients. This prospective comparative study, at the University of Paris XI, Assistance Publique des Hopitaux de Paris, INSERM Unit 782, was performed on 165 infertile IVF embryo transfer candidates. A total of 271 consecutive minimal stimulation IVF cycles were studied. Oocyte retrieval was performed 34 h after human chorionic gonadotrophin administration and oocytes were allocated into two groups according to their retrieval method: oocytes obtained in the first follicular aspiration (FA, n = 127); and oocytes retrieved in the subsequent follicular flushing (FF, n = 102). The principal outcome was to evaluate clinical pregnancy and embryo implantation rates. Thus, patient characteristics, fertilization rate and clinical pregnancy rate per oocyte were comparable in both of groups. In contrast, embryo morphology (41 versus 59%, P < 0.01) and implantation rates (20.4 versus 34.8%, P < 0.04) were better in the FF group. In conclusion, an optimal reproductive competence was observed in oocytes retrieved by follicular flushing in minimal stimulation IVF in poor responder patients. 相似文献

Due to the absence of easily applicable cut‐off points to determine high blood pressure or hypertension in children, as in the adult population, blood pressure is rarely measured in the pediatrician''s clinical routine. This has led to an underdiagnosis of high blood pressure or hypertension in children. For this reason, the present study evaluate the utility of five equations for the screening of high blood pressure in children: blood pressure to height ratio, modified blood pressure to height ratio, new modified blood pressure to height ratio, new simple formula and height‐based equations. The authors evaluated 1599 children between 5 and 18 years. The performance of the five equations was analyzed using the receiver‐operating characteristics curves for identifying blood pressure above P90th according to the American Academy of Pediatrics Clinical Practice Guideline 2017. All equations showed an area under the curve above 0.882. The new modified blood pressure to height ratio revealed a high sensitivity whereas the height‐based equations showed the best performance, with a positive predictive value above 88.2%. Finally, all equations showed higher positive predictive values in children with overweight or obesity. The height‐based equation obtained the highest PPV values above 71.1% in children with normal weight and above 90.2% in children with overweight or obesity. In conclusions, the authors recommend the use of the height‐based equations equation because it showed the best positive predictive values to identify children with elevated blood pressure, independently of their sex, pubertal and weight status. 相似文献

The essential oils of the three aromatic plants Lippia multiflora, Melaleuca leucadendron and Erigeron floribundus collected in Ivory Coast were analyzed by GC and GC/MS; their chemical compositions were compared to those of their headspace extracted by a Monotrap method. The major components of Lippia multiflora essential oil were the same in its headspace: linalool, 1,8-cineole, (E)-nerolidol and citral. The essential oil of Melaleuca leucadendron as well as its headspace were dominated by 1,8-cineole, viridiflorol and α-terpineol. Limonene, (Z)-β-farnesene, (E)-β-caryophyllene and (Z)-methyl lachnophyllate were the major components of Erigeron floribundus essential oil while its headspace was characterized by high amounts of limonene, myrcene and germacrene D. The essential oils were tested against Bemisia tabaci using a fumigation method. The three samples presented an insecticidal activity after 24 hours. Nevertheless, Erigeron floribundus essential oil was less efficient compared to the other ones. The relationship chemical composition/biological activity and the potential uses of these essential oils as biopesticides are discussed. 相似文献

Primary cystic pancreatic neoplasms are rare tumors, with an approximate prevalence of 10% of cystic pancreatic lesions. Most of these lesions correspond to mucinous cystic neoplasm, serous cystoadenoma and intraductal papillary mucinous tumor (IPMT). IPMT is characterized by diffuse dilatation of the main pancreatic duct and/or side branches with inner defects related to mucin or tumor, or mucin extrusion from a patent ampulla. IPMT has a low potential for malignancy, with a low growth rate, a low rate of metastatic spread and postsurgical recurrence. Over the last few years, major advances have been made in the diagnostic and therapeutic management of this tumor. 相似文献
