Diagnosis of polycystic ovary syndrome: from NIH criteria to ESHRE-ASRM guidelines.
2004
In the past, the diagnosis of polycystic ovary syndrome (PCOS) was based on National Institute of Health (NIH) criteria (hyperandrogenism and chronic anovulation) or on sonographic findings of polycystic ovaries. Diffe-rences in diagnosis criteria made it difficult to compare the data of studies coming from different countries. Moreover, there was criticism of both the methods used. In 2003, at a joint meeting of the European Society for Human Reproduction (ESHRE) and the American Society of Reproductive Medicine (ASRM), new guidelines for the diagnosis of PCOS were suggested. According to these guidelines, it is possible to reach a diagnosis of PCOS when at least 2 of these 3 elements are …
Oral dysphagia. An unique symptom for a wide spectrum of diseases
2009
Dysphagia, defined as a difficulty in swallowing of fluids and/or solid foods, is one of the most frequent symptoms of esophageal, gastrointestinal, ear, nose and throat diseases. As such, it poses a diagnostic challenge and an interdisciplinary clinical problem. Of particular importance in diagnosis is to distinguish between esophageal and oropharyngeal dysphagia. Oropharyn-geal dysphagia is often associated with neuromuscular disorders and is treated with rehabilitative protocols, while esophageal dysphagia may be due to anatomical alterations and esophageal motility difficulties. While the former can be adequately treated with endoscopic or surgical therapy, the latter are currently trea…
Role of computational modeling in thoracic aortic pathology: A review
2014
Thoracic aortic diseases are life-threatening conditions causing significant mortality and morbidity despite advances in diagnostic and surgical treatments. Computational methods combined with imaging techniques provide quantitative information of disease progression, which may improve clinical treatments and therapeutic strategies for clinical practice. Since hemodynamic and wall mechanics play important roles in the natural history and progression of aortic diseases, we reviewed the potential application of computational modeling of the thoracic aorta. We placed emphasis on the clinical relevance of these techniques for the assessment of aortic dissection, thoracic aortic aneurysm, and ao…
Imaging techniques in inflammatory bowel disease: recent trends, questions and answers
2009
Summary Imaging techniques have undergone substantial progress in recent years and contribute significantly in the diagnosis of inflammatory bowel diseases in conjunction with patient history, clinical and laboratory examination. Modern cross-sectional imaging modalities such as computed tomography and magnetic resonance imaging allow an evaluation not only of the complete bowel wall of the small intestine, but also of extraluminal structures. They constitute a major diagnostic component in the initial workup, in stricturing or fistulizing disease and in suspected abscess. Transabdominal ultrasonography has been re-appreciated in these settings as an easy- and ready-to-use tool yielding rea…
Budd-Chiari Syndrome: Spectrum of Imaging Findings
2007
OBJECTIVE: The objective of our study was to illustrate the imaging findings of Budd-Chiari syndrome, including CT, MRI, sonographic, and angiographic findings. CONCLUSION: The key imaging findings in Budd-Chiari syndrome are occlusion of the hepatic veins, inferior vena cava, or both; caudate lobe enlargement; inhomogeneous liver enhancement; and the presence of intrahepatic collateral vessels and hypervascular nodules. Awareness of these findings is important for early diagnosis and appropriate treatment.
Objective, Noninvasive Evaluation of Velopharyngeal Function in Cleft and Noncleft Patients
1998
Objective The purpose of this study was to investigate a new diagnostic method that provides an approach to noninvasive, objective measurement of velopharyngeal movement by acoustic determination of epipharyngeal volume changes with velopharyngeal muscle function. Design This was a case control study, using consecutive samples. Setting This study took place at the Cleft Palate Rehabilitation Center of the University of Mainz, Germany. Patients Subjects were 29 consecutive cleft lip and palate (CLP) patients and 31 controls (21 patients with dysgnathia and 10 healthy volunteers). Intervention A series of transnasal acoustic measurements (pressure wave: 55 dB for 2 milliseconds) of epipharyng…
Detection of enteric adenoviruses 40 and 41 in stool specimens by monoclonal antibody-based enzyme immunoassays
1996
To examine the role of enteric adenoviruses (Ad40 and Ad41) in children with acute gastroenteritis, we evaluated 273 children with diarrhoea and 137 without enteric symptoms in Palermo, Italy, during an 8-month period. Stools were tested by two home-made monoclonal-based ELISAs to detected genus-specific adenovirus antigen and to type Ad40 and Ad41. Twenty-five samples (6.1%) were found to contain adenovirus, 18 of which were grown in Graham 293 and in HEp-2 cells. Ad40 and Ad41 were detected in 2.6% of children with diarrhoea and in none in the control group, while non-enteric adenoviruses were obtained from both patients (3.2%) and controls (6.5%). Samples containing Ad40 and Ad41 were po…
La atenuación en conversaciones coloquiales argentinas y españolas: un estudio contrastivo
2018
El objetivo de este artículo es presentar el resultado de un análisis contrastivo realizado entre las manifestaciones de atenuación en conversaciones coloquiales argentinas y españolas. La atenuación, como fenómeno pragmático que reduce la fuerza ilocutiva de los actos comunicativos, en el que intervienen la imagen y las responsabilidades de los hablantes respecto a sus mensajes (Caffi 1999, 2007; Thaler; Albelda 2016), ha sido ampliamente estudiada para el español, a partir de la década de los 90, desde la perspectiva de los estudios de cortesía (Haverkate; Briz 1995, 2007), la pragmática (Schneider) o la sociolingüística (Samper Hernández; Cestero). Sin embargo, son escasos los trabajos q…
Dietary fiber and health outcomes: an umbrella review of systematic reviews and meta-analyses
2018
Background Several studies have suggested that higher consumption of dietary fiber is beneficial for a variety of health outcomes. However, many results have been inconclusive and, to our knowledge, there has been no attempt to systematically capture the breadth of outcomes associated with dietary fiber intake or to systematically assess the quality and the strength of the evidence on the associations of dietary fiber intake and different health outcomes or medical conditions. Objective The aim of this study was to describe the diverse health outcomes convincingly associated with dietary fiber consumption. Design This was an umbrella review of systematic reviews with meta-analysis of observ…
Fiber intake and all-cause mortality in the Prevención con Dieta Mediterránea (PREDIMED) study
2014
Background: Few observational studies have examined the effect of dietary fiber intake and fruit and vegetable consumption on total mortality and have reported inconsistent results. All of the studies have been conducted in the general population and typically used only a single assessment of diet. Objective: We investigated the association of fiber intake and whole-grain, fruit, and vegetable consumption with all-cause mortality in a Mediterranean cohort of elderly adults at high cardiovascular disease (CVD) risk by using repeated measurements of dietary information and taking into account the effect of a dietary intervention. Design: We followed up 7216 men (55-75 y old) and women (60-75 …
