Diferencias entre sexos en pacientes con sospecha de síndrome coronario agudo sin elevación del segmento ST. Implicaciones en el tratamiento interven…
2003
Sex differences have been observed in the clinical profile, prognosis, and treatment of patients with unstable ischemic heart disease. Men tend to receive more invasive management. We assessed these differences in 823 consecutive patients (543 men) with possible acute coronary syndrome without ST-segment elevation who were seen since our chest pain unit opened. A protocol for the management of unstable ischemic heart disease was followed. Women had a worse baseline clinical profile but men more frequently had a positive exercise stress test. Univariate analysis showed that angiography and revascularization procedures were performed more often in men. However, multivariate analysis did not c…
Vasodilator Stress CMR and All-Cause Mortality in Stable Ischemic Heart Disease
2020
Abstract Objectives This study explored the association of ischemic burden, as measured by vasodilator stress cardiovascular magnetic resonance (CMR), with all-cause mortality and the effect of revascularization on all-cause mortality in patients with stable ischemic heart disease (SIHD). Background In patients with SIHD, the association of ischemic burden, derived from vasodilator stress CMR, with all-cause mortality and its role for decision-making is unclear. Methods The registry consisted of 6,389 consecutive patients (mean age: 65 ± 12 years; 38% women) who underwent vasodilator stress CMR for known or suspected SIHD. The ischemic burden (at stress first-pass perfusion imaging) was com…
Reperfusion of liver graft during transplantation: techniques used in transplant centres within Eurotransplant and meta-analysis of the literature
2013
Abstract: It remains unclear which liver graft reperfusion technique leads to the best outcome following transplantation. An online survey was sent to all transplant centres (n=37) within Eurotransplant (ET) to collect information on their technique used for reperfusion of liver grafts. Furthermore, a systematic review of all literature was performed and a meta-analysis was conducted based on patients' mortality, number of retransplantations and incidence of biliary complications, depending on the technique used. Of the 28 evaluated centres, 11 (39%) reported performing simultaneous reperfusion (SIMR), 13 (46%) perform initial portal vein reperfusion (IPR), 1 (4%) performs an initial hepati…
Beals–Hecht syndrome and choroidal neovascularization
2010
PURPOSE To describe a case of choroidal neovascularization (CNV) in a female diagnosed with Beals-Hecht syndrome. METHODS A retrospective, interventional case is described in a 26-year-old female complaining of metamorphopsia and visual loss in her left eye (counting fingers). The fluorescein angiogram and the optical coherence tomography supported the diagnosis of CNV. Intravitreal ranibizumab was administered. RESULTS After the third intravitreal ranibizumab, her visual acuity improved to 0.8 and the morphology of the macular area was restored. CONCLUSIONS To our knowledge this is the first report of CNV in Beals-Hecht syndrome treated with ranibizumab. Self-monitoring by periodically per…
Observational outcomes in proliferative diabetic retinopathy patients following treatment with ranibizumab, panretinal laser photocoagulation or comb…
2021
Purpose Ranibizumab monotherapy showed stronger effects on area of retinal neovascularization (NV) reduction while offering better visual acuity (VA) results than panretinal laser photocoagulation (PRP) monotherapy during the first 12 months of the PRIDE study. The second year of PRIDE was an observational, non-interventional follow-up, performed to evaluate long-term anatomical and functional outcomes in proliferative diabetic retinopathy (PDR) patients under real-life conditions, prior to the approval of ranibizumab for PDR. Methods Seventy-three PDR patients (28 from the ranibizumab group; 20 from the PRP group; 25 from the combination group) were included in the observational follow-up …
Automated macular choroidal thickness measurement by swept-source optical coherence tomography in pseudoxanthoma elasticum
2016
Introduction Pseudoxanthoma elasticum (PXE) typically involves elastic fibers in blood vessels and Bruch membrane. Our purpose was to analyze retinal and choroidal macular thickness in patients with angioid streaks due PXE compared with a control group. Methods Best-corrected visual acuity (BCVA), axial length (AL), and macular swept-source optical coherence tomography were obtained. Automated segmentations of the retina and the choroid were used to obtain the corresponding thickness values. An age, gender and AL matched control group was used to compare the thickness values. Results Twelve eyes of 6 patients were included. The mean BCVA was 0.68 ± 0.29 versus 1.0 in controls (p < 0.001). T…
Efficacy and safety of ranibizumab with or without panretinal laser photocoagulation versus laser photocoagulation alone in proliferative diabetic re…
2019
Purpose Panretinal photocoagulation (PRP) is the current standard of care in proliferative diabetic retinopathy (PDR). However, treatment with anti-vascular endothelial growth factor agents might offer better patient outcomes with fewer side-effects. The PRIDE study aimed to assess the efficacy and safety of ranibizumab with or without PRP compared with PRP alone in patients with PDR. Methods A total of 106 PDR patients without diabetic macular oedema were randomized to receive ranibizumab 0.5 mg monotherapy (n = 35), PRP (n = 35) or combined ranibizumab 0.5 mg/PRP (n = 36). The primary objective of this 12-month, multicentre, phase II study was to investigate the change in area of retinal …

Morphologische und funktionelle Ergebnisse nach transpupillarer Thermotherapie (TTT) maligner Aderhautmelanome
2006
BACKGROUND The aim of this study was to evaluate the course of tumor regression and visual impairment in choroidal melanomas treated by transpupillary thermotherapy (TTT) alone. PATIENTS AND METHODS In a prospective, non-randomized analysis 26 patients suffering from primary choroidal melanoma (posterior to the equator with base < or = 12 and thickness < or = 4.5 mm) were treated with the TTT standard protocol and followed for 33 - 45 months. Fluorescein and ICG angiographies were performed initially and after tumor regression clinically. RESULTS 22 tumors were significantly flattened after 1 - 3 TTT sessions. 4 tumors required additional therapy with ruthenium plaque. Visual acuity remaine…
Secretagogues Modulate the Calcium Concentration in the Endoplasmic Reticulum of Insulin-secreting Cells
1999
The precise regulation of the Ca2+ concentration in the endoplasmic reticulum ([Ca2+]er) is important for protein processing and signal transduction. In the pancreatic beta-cell, dysregulation of [Ca2+]er may cause impaired insulin secretion. The Ca2+-sensitive photoprotein aequorin mutated to lower its Ca2+ affinity was stably expressed in the endoplasmic reticulum (ER) of rat insulinoma INS-1 cells. The steady state [Ca2+]er was 267 +/- 9 microM. Both the Ca2+-ATPase inhibitor cyclopiazonic acid and 4-chloro-m-cresol, an activator of ryanodine receptors, caused an almost complete emptying of ER Ca2+. The inositol 1,4,5-trisphosphate generating agonists, carbachol, and ATP, reduced [Ca2+]e…
