Identification of calcium sensing receptor (CaSR) mRNA-expressing cells in normal and injured rat brain
2009
Calcium sensing receptor (CaSR), isolated for the first time from bovine and human parathyroid, is a G-protein-coupled receptors that has been involved in diverse physiological functions. At present a complete in vivo work on the identification of CaSR mRNA-expressing cells in the adult brain lacks and this investigation was undertaken in order to acquire more information on cell type expressing CaSR mRNA in the rat brain and to analyse for the first time its expression in different experimental models of brain injury. The expression of CaSR mRNAs was found mainly in scattered cells throughout almost all the brain regions. A double labeling analysis showed a colocalization of CaSR mRNA expr…
An abdominal aortic aneurysm (AAA) in combination with duplication of the inferior vena cava (IVC), the right renal artery (RRA) and the right renal …
1990
Intra-abdominal abnormality of vessels may sometimes lead to complications. A case of the rare combination of an abdominal aortic aneurysm (AAA) at the origin of the inferior mesenteric a. with duplications of the inferior vena cava (IVC), the right renal a. (RRA) and the right renal v. (RRV) as well as absence of the left common iliac v. is reported.
Technical Report: Repeatability of Contrast Sensitivity Test in Children
2020
Contrast sensitivity (CS) in children is not routinely measured in the clinical setting, although CS losses have been found in amblyopic and premature children. Thus simple visual acuity measurements do not completely assess their quality of vision. To evaluate contrast sensitivity in children, a reliable and easy test, sampling the entire spatial frequency range, is necessary. Purpose This study aimed to evaluate the repeatability and normal range of the contrast sensitivity function measured using the Topcon CC-100 instrument, in children aged between 4 and 9 years, for use as a diagnostic tool. Methods Contrast sensitivity was measured in 25 children, 11 boys and 14 girls, with normal or…
Variables affecting the quality of anticoagulation in atrial fibrillation patients newly initiating vitamin K antagonists: insights from the national…
2021
Abstract Aims Vitamin K antagonists (VKAs) are effective drugs reducing the risk for stroke in atrial fibrillation (AF), but the benefits derived from such therapy depend on the international normalized ratio (INR) maintenance in a narrow therapeutic range. Here, we aimed to determine independent variables driving poor anticoagulation control [defined as a time in therapeutic range (TTR) <65%] in a ‘real world’ national cohort of AF patients. Methods and results The SULTAN registry is a multicentre, prospective study, involving patients with non-valvular AF from 72 cardiology units expert in AF in Spain. At inclusion, all patients naïve for oral anticoagulation were started with VKAs…
Relevance of Polypharmacy for Clinical Outcome in Patients Receiving Vitamin K Antagonists.
2018
BACKGROUND Although polypharmacy is associated with a negative clinical outcome in various settings and commonly observed in patients receiving oral anticoagulation therapy, evidence on the relevance for the clinical outcome of anticoagulated patients is currently limited. The aim of the study was to investigate the effect of polypharmacy on the clinical outcomes among patients taking phenprocoumon. DESIGN Prospective cohort study. SETTING Regular medical care. PARTICIPANTS Information on 2011 individuals receiving vitamin K antagonists was available for analysis from the prospective multicenter thrombEVAL study. MEASUREMENTS Data were obtained from clinical visits, computer-assisted interv…
Oral vitamin K effectively treats international normalised ratio (INR) values in excess of 10
2009
SummaryUnanticipated elevation of the INR is common in patients receiving warfarin. We performed a prospective cohort study of 107 warfarintreated patients with INR values of more than 10 who received a single 2.5 mg dose of oral vitamin K. During the first week, one patient experienced major bleeding, and one died. In the first 90 days after enrolment four patients had major bleeding (3.7%, 1.0% to 9.3%), eight patients (7.5%, 3.3% to 14.2%) died and two had objectively confirmed thromboembolism. Based on our low rate of observed major bleeding we conclude that 2.5 mg of oral vitamin K is a reasonable treatment for patients with INR values of more than 10 who are not actively bleeding.
Comparison of the influence of corneo-scleral and scleral lenses on ocular surface and tear film metrics in a presbyopic population
2018
PURPOSE: To assess and compare the effect of the corneo-scleral lenses (C-ScL) and scleral lenses (ScL) on tear film parameters and central corneal thickness (CCT) in healthy presbyopic subjects. METHODS: Thirty subjects wore two contact lenses (CLs), randomly assigned, of neutral power, but of different diameters, 12.7mm (C-ScL) and 18mm (ScL) and being equal in the others parameters: material (HS100) and centre thickness (0.29mm). At baseline, 20min after insertion and at 8h, the tear meniscus area (TMA) and CCT was measured (with optical coherence tomography) as well as tear osmolarity. RESULTS: TMA revealed statistical differences for both lenses at 20min (p<0.001), and also at 8h (p=0.…
The hypothetical role of congenital hypotonia in the development of early coronoid hyperplasia
2012
Abstract Background Coronoid hyperplasia (CH) is an abnormal bony elongation of a histologically normal coronoid process. Its definitive cause remains unknown. Objectives To analyze the possible implication of congenital hypotonia in the pathogenesis of early coronoid overgrowth. Patients and methods Two infants with congenital hypotonia were evaluated for limited mouth aperture. Bilateral CH was diagnosed. Transoral coronoidectomy was followed by an early dynamic physiotherapy program. Results Significant improvement of maximum interincisal opening was achieved. The review of the scientific literature proved the diagnosis of CH in the infant age group is extremely unusual and the etiology …
Prognostic Role of Late Gadolinium Enhancement in Patients With Hypertrophic Cardiomyopathy and Low-to-Intermediate Sudden Cardiac Death Risk Score
2019
Sudden cardiac death (SCD) is the most life-threating complication of hypertrophic cardiomyopathy. Guidelines of the European Society of Cardiology (ESC) suggest the implantation of an implantable cardioverter defibrillator in primary prevention according to a 5-year risk SCD score >= 6%. The aim of the study is to evaluate the prognostic role of late gadolinium enhancement (LGE) in patients with a 5-year risk SCD score <6%. In this multicenter study, we performed cardiac magnetic resonance in 354 consecutive hypertrophic cardiomy-opathy patients (257 males, range of age 54 +/- 17) with a risk SCD score <6% (302 with <4% and 52 with >= 4 and <6% risk). Hard cardiac events,…
Overlapping phenotypes between SHORT and Noonan syndromes in patients with PTPN11 pathogenic variants
2020
Overlapping syndromes such as Noonan, Cardio-Facio-Cutaneous, Noonan syndrome (NS) with multiple lentigines and Costello syndromes are genetically heterogeneous conditions sharing a dysregulation of the RAS/mitogen-activated protein kinase (MAPK) pathway and are known collectively as the RASopathies. PTPN11 was the first disease-causing gene identified in NS and remains the more prevalent. We report seven patients from three families presenting heterozygous missense variants in PTPN11 probably responsible for a disease phenotype distinct from the classical Noonan syndrome. The clinical presentation and common features of these seven cases overlap with the SHORT syndrome. The latter is the c…
