Trends in mortality related to pulmonary embolism in the European Region, 2000-15: analysis of vital registration data from the WHO Mortality Database
2020
Summary Background European estimates of the burden imposed by pulmonary embolism are not available to this date. We aimed to assess pulmonary embolism-related mortality and time trends in the WHO European Region. Methods We analysed vital registration data from the WHO Mortality Database (2000–15) covering subregions of the WHO European Region: Eastern Europe, Northern Europe, Southern Europe, Western Europe, and Central Asia. Deaths were considered pulmonary embolism-related if International Classification of Disease-10 code for acute pulmonary embolism (I26) or any code for deep or superficial vein thrombosis was listed as the primary cause of death. We used locally estimated scatterplot…
Photodynamic therapy with verteporfin for subfoveal choroidal neovascularization secondary to pathologic myopia: long-term study.
2006
Purpose: To assess the safety and effectiveness of photodynamic therapy (PDT) with verteporfin for subfoveal choroidal neovascularization (CNV) secondary to pathologic myopia (PM). Methods: Sixty-two patients (62 eyes) with PM underwent PDT according to the guidelines of the Verteporfin in Photodynamic Therapy Study. Clinical evaluations performed at all study visits included measurement of best-corrected Snellen visual acuity, slit-lamp biomicroscopy, and fundus fluorescein angiography. Patients were followed up at 1 month and 3 months after treatment and thereafter at 3-month intervals. Results: The final visual acuity of the study patients, after a median follow-up of 31 months, improved…
Odontogenic cysts: Demographic profile in a Brazilian population over a 38-year period
2009
Objective: To determine the distribution of odontogenic cysts diagnosed histologically over a period of 38 years in a Brazilian population according to age, gender and site affected and to compare these data with previously reported studies from other countries. Study design: A total of 1019 cases of odontogenic cysts diagnosed between 1970 and 2007 were studied. Clinical features obtained from the patient records and microscope slides were reviewed according to the 1992 World Health Organization classification. Results: The mean age was 31.0 years, and there was a predominance of females. The most frequent odontogenic cysts were radicular cysts (61.4%), followed by dentigerous cysts (20.1%…
Economic aspects of different muscle relaxant regimens.
2000
Objective At a time of cost reduction in medical care efforts to manage the ever-increasing costs of new pharmaceutical drugs become increasingly important. Costs of four different muscle relaxant regimens including the new intermediate-acting neuromuscular blocking drugs (NMBD) cisatracurium and rocuronium will be analyzed. Methods Eighty patients undergoing laparoscopic cholecystectomy were prospectively studied. All patients received standardized general anaesthesia with desflurane/fentanyl. Muscle relaxation was achieved with atracurium, cisatracurium, vecuronium, or rocuronium with 20 patients in each group. Intraoperatively muscle relaxants were added to maintain two twitches of the t…
Smile esthetics from odontology students' perspectives
2013
ABSTRACT Objectives: To analyze the perception of smile esthetics and its alterations in dental degree students; to determine whether there are differences in that perception among students in different study years on those courses and between genders; and to determine if the circumstance of having received prior orthodontic treatment could influence that perception. Material and Methods: Students (n = 192) in different study years of the dental degree course at the University of Valencia, Spain, analyzed two photographs of a patient in which, by means of computer software, midline diastema, upper and lower midlines, crown length of the maxillary right central incisor, occlusal cant, and “g…
Further Neuroimaging Evidence for the Deficit Subtype of Schizophrenia
2015
The clinical heterogeneity of schizophrenia has hindered neurobiological investigations aimed at identifying neural correlates of the disorder.To identify network-based biomarkers across the spectrum of impairment present in schizophrenia by separately evaluating individuals with deficit and nondeficit subtypes of this disorder.A university hospital network-based neuroimaging study was conducted between February 1, 2007, and February 28, 2012. Participants included patients with schizophrenia (n = 128) and matched healthy controls (n = 130) from two academic centers and patients with bipolar I disorder (n = 39) and matched healthy controls (n = 43) from a third site. Patients with schizophr…
Lymphocyte beta-adrenergic receptors in young subjects with peripheral or central obesity: relationship with central haemodynamics and left ventricul…
1994
This study was designed to evaluate total (t) and surface (s) β-adrenergic receptor (BAR) density and their relationship with central haemodynamics and left ventricular function in young subjects with central or peripheral obesity. A total of 31 obese subjects (BMI ≥30.5 kg. m−2 for males and >27.3 kg. m−2 for females) aged less than 40 years and without other risk factors for cardiovascular diseases (smoking, hypertension, diabetes and lipid abnormalities) were studied. Nine had peripheral obesity and 22 central obesity according to WHR values; there were 20 lean controls (BMI <25 kg. m−2 for males and <24.7 kg. m−2 for females). Casual (c) and 24 h ambulatory mean blood pressures (MBP-24 …
Real-time ultrasound-guided infraclavicular axillary vein cannulation: A prospective study in mechanically ventilated critically ill patients.
2016
Purpose: The main purpose of this study was to define the venipuncture and catheterization success rates and early mechanical complication rates of ultrasound-guided infraclavicular axillary vein cannulation. Materials and methods: We performed in-plane, real-time, ultrasound-guided infraclavicular axillary vein catheterizations under emergency and nonemergency conditions in mechanically ventilated, critically ill patients. Results: We performed 202 cannulation attempts. One hundred and twenty-six procedures (62.4%) were performed under emergency conditions. The puncture of the axillary vein was successful in 98.5% of patients, and the entire procedure success rate was 95.1% (95% confidence…
Home parenteral nutrition-associated thromboembolic and bleeding events: results of a cohort study of 236 individuals
2016
UNLABELLED Essentials Sparse or outdated studies focus on thrombotic and bleeding risk in home parenteral nutrition (HPN). 236 HPN patients followed at a single center for a total of 684 patient-years were evaluated. Rates of venous thrombosis and major bleeding, and prevalence of vena cava syndrome are provided. Anticoagulants might reduce thrombosis risk, but population-specific safety concerns remain. SUMMARY Background Home parenteral nutrition (HPN) is necessary for patients with intestinal failure. Recurrent catheter-related thrombosis (CRT) is common, leading to infectious complications, pulmonary embolism, vascular access loss and intestinal transplantation. The efficacy and safety …
Minimally invasive cerebral cavernoma surgery using keyhole approaches - solutions for technique-related limitations.
2009
Cavernomas are often small in size and located in difficultly accessible regions. Preoperative identification of the ideal surgical approach as well as the precise intraoperative implementation of the surgical plan are of critical importance for successful surgery. While aiming for minimally invasive surgical techniques and maximally effective cavernoma resection, we envisaged that employing a combination of precise and technically sophisticated virtual reality surgery planning, modern navigation systems with augmented reality features and endoscope-assisted surgical techniques should contribute to achieve this goal. Between December 2002 and November 2005, 66 patients were operated on for …
