Discriminant analysis in diagnosing carcinoma of the pancreas and of the papilla of Vater
1994
The clinical and biochemical presentation of carcinoma of the pancreas (PC) and of the papilla of Vater (CPV) are very similar, and, consequently, detailed investigations are required to correctly distinguish between them. The aim of the present study was to select the clinical and biochemical variables that would most efficiently discriminate the precise site of tumor origin. The study group consisted of 72 patients with PC and 22 patients with CPV consecutively hospitalized in our department. The following clinical parameters were considered: age, asthenia, anorexia, vomiting, weight loss, pain, fever, pruritis, and constipation; the biochemical parameters considered were total, direct, a…
Failure of opioids to affect excitation and contraction in isolated ventricular heart muscle
1989
The opioid agonists morphine (selective for mu-receptors) and ethylketocyclazocine (selective for kappa-receptors), at concentrations evoking strong effects in neuronal structures, did not significantly affect the configuration of the intracellularly recorded action potential and the force of contraction in ventricular heart muscle isolated from guinea pigs, rabbits and man. These results suggest that any changes of heart functions in vivo in response to opioid-like drugs are probably not mediated postsynaptically at the myocardial cell membrane but rather presynaptically, influencing the release of noradrenaline and/or acetylcholine from the nerve terminals.
Increased risk for cervical disease progression of French women infected with the human papillomavirus type 16 E6-350G variant.
2006
Abstract To test the significance of human papillomavirus (HPV) type 16 and HPV16 E6 variants as risk factors for viral persistence and progression to high-grade lesion, we did a nested case-control study within a cohort study of >15,000 Caucasian French women. Three groups infected with high-risk HPV were compared: (a) women with cleared infection (controls, n = 201), (b) women with persistent infection (cases, n = 87), and (c) women who progressed into high-grade lesion (cases, n = 58). Women with persistent HPV infection and those that progressed into high-grade lesions were likelier to harbor HPV16 than other high-risk HPV types [odds ratio (OR), 2.4; 95% confidence interval (95%…
Human papilloma virus genotypes in dysplasia and epithelial hyperplasia of oral cavity using the luminex xmap technology. A multicenter study
2019
Background Oral cancer associated with high risk (HPV-HR) human papilloma virus (HPV) has been increasing. HPV-HR has been associated with epithelial dysplasia, however, little information exists on its frequency in epithelial hyperplasia lesions. The aim of this study is to compare HPV genotypes in dysplastic and hyperplastic lesions of oral cavity. Material and Methods Two hundred and fifty oral lesions: 131 dysplasia and 119 hyperplasia from two regions of Colombia were evaluated. One hundred seventy-four coming from urban area and 104 from a high risk population to oral cancer from a rural area. HPV was identified by qPCR and Twenty-four HPVs genotypes were evaluated by Luminex® technol…
Knowledge about infection with human papillomavirus: a systematic review.
2007
Abstract Objective. Human papillomavirus (HPV) is a necessary cause of cervical cancer and genital warts. The aim of this systematic literature review was to provide an overview of knowledge about HPV infection among the public, students, patients and health professionals. Method. PubMed searches were performed and the results of studies were reported by age, gender, study population, country, recruitment score and year of study conduct. The recruitment score covered the mode of recruitment, study size and response rate. Results. We included 39 studies published between 1992 and 2006 covering a total of 19,986 participants. The proportion of participants who had heard of HPV varied from 13%…
ELS live surgery: a developing story
2019
Since 2015, the European Laryngological Society (ELS) has organized on a yearly basis the European Laryngological Live Surgery Broadcast. The goal of this paper is to demonstrate the increasing worldwide audience. The number of individual computers logged in, number of estimated audience, and number of countries with an active audience were calculated and compared to the numbers in 2015. In 2018, 19 live interventions were performed in three parallel sessions. The surgeons worked in 10 departments in 8 different countries. The number of individual computers logged in increased from 1000 in 2015 to 16000 in 2018. The estimated audience increased from 3000 to 32000 visitors. The number of cou…
Multiplane Two-Dimensional versus Real Time Three-Dimensional Transesophageal Echocardiography in Ischemic Mitral Regurgitation
2011
Objectives: Intraoperative three-dimensional (3D) transesophageal echocardiography (TEE) has been suggested to be a valuable technique for the evaluation of the mechanisms of ischemic mitral regurgitation (IMR). Studies comparing multiplane two-dimensional (2D) with 3D TEE reconstruction of the mitral valve using the new mitral valve quantification (MVQ) software are lacking. We undertook a prospective comparison between multiplane 2D and 3D TEE for the assessment of IMR. Methods: We evaluated echocardiographically 45 patients with IMR who underwent mitral valve surgery in our institution. 2D and 3D TEE examinations followed by a 3D offline assessment of the mitral valve apparatus were perf…
Diagnostic value of transesophageal echocardiography in patients with coronary artery disease and mitral insufficiency
1991
Any diagnosis of mitral regurgitation must always include the etiology. The clinical history is only rarely informative, as are chest x-ray examinations. The ECG is of value to diagnose coronary artery disease with or without previous myocardial infarction — but further differentiation is not possible. During heart catheterization mitral insufficiency can be diagnosed and quantified according to Seller’s classification [1]. A differentiation of etiology is only rarely possible. Rheumatic heart disease and mitral valve prolapse can be differentiated.
