Nd:YAG-Laserung einer retrohyaloidalen Blutung nach Venenastverschluss
2006
Background A retrohyaloidal haemorrhage can be caused by different underlying diseases. Usually dense haemorrhages are treated by early vitrectomy. We want to report the successful treatment of a retrohyaloidal haemorrhage by means of Nd:YAG laser membranotomy. Materials and methods A 47-year-old man noticed two weeks before presentation a sudden visual loss in the left eye. Visual acuity on the first visit was c. c. 20/32 OD and c. c. 20/400 ex. OS. Dilated fundus examination of the left eye showed multiple intraretinal haemorrhages in the superior periphery and a dense retrohyaloidal haemorrhage over the macula. Anamnestic risk factors for ocular bleeding were systemic hypertension in con…
Photodynamic Therapy in Subfoveal Choroidal Neovascularisation
2002
Summary The exudative form of age-related macular degeneration (AMD) is the leading cause of blindness among people over 50 years of age in the western world. In 2–10% of cases a subfoveal choroidal neovascularisation develops. Conventional laser treatment leads to an unspecific destruction of the CNV including adjacent retinal structures. In addition, significant and immediate vision loss occurs, particularly in cases with central, subfoveal localization of the CNV.Photodynamic therapy (PDT) employing photochemical activation of verteporfin as a photosensitizer induces selective occlusion of CNV with minimal damage to the neurosensory retina and does not impair visual acuity. It became ava…
Acquired Ocular Toxoplasmosis
1991
A 31-year-old man exhibited a bilateral deterioration of vision over the course of 1 week. The right fundus showed the picture of a central vein occlusion, and the left of a disseminated choroiditis. Indirect immunofluorescent testing indicated a titer of 1:2048 for toxoplasmosis. Fluorescein angiography revealed a hitherto unique picture of isolated choroidal occlusions but neither a central vein occlusion nor a disseminated choroiditis. Using only specific antitoxoplasmotic therapy, the patient regained full visual acuity on both sides. The original findings and the results of a 14-year follow-up are presented.
Consensus statements and clinical recommendations on treatment indications, surgical procedures, prosthetic protocols and complications following All…
2017
Objectives The present consensus report critically evaluates the scientific evidence based on a comprehensive systematic review of the All-On-4 treatment concept, focusing primarily on the treatment indications, surgical procedures and prosthetic protocols, and secondarily on the mechanical and biological complications involved. Material and Methods A systematic review was made in advance of the meeting. Consensus statements, treatment guidelines and recommendations for future research were based on within-group as well as plenary debates and discussions of the systematic review. Results The main indication of All-On-4 standard care is an atrophic maxilla or mandible, with or without remnan…
What is the accuracy of the surgical guide in the planning of orthognathic surgeries? A systematic review.
2021
BACKGROUND To investigate the true accuracy of the surgical guide in the planning of orthognathic surgeries, which are performed worldwide. MATERIAL AND METHODS A systematic search was conducted in the PubMed database, Web of science, Scopus and Embase, covering August 2020 to January 2021. Studies that included patients with dentofacial deformity including anteroposterior, vertical and asymmetry problems who were undergoing an orthognathic surgery procedure were included; QUADAS-2 was used to determine the risk of bias by analyzing the quality of the studies. A PRISMA (flowchart) was created to show the study selection, keywords, nomination processes, and inclusion and exclusion criteria. …
Working Memory, Jumping to Conclusions and Emotion Recognition: a Possible Link in First Episode Psychosis (Fep)
2015
Introduction A large body of literature has demonstrated that people affected by psychotic disorders show deficits in working memory, in Emotion Recognition (ER) and in data-gathering to reach a decision (Jumping To Conclusions – JTC). Aims To investigate a possible correlation between working memory, JTC and ER in FEP. Methods 41 patients and 89 healthy controls completed assessments of working memory using WAIS shortened version, JTC using the 60:40 Beads Task and ER using Degraded Facial Affect Recognition Task. Results According to the literature, cases had poorer performance in working memory tasks (Digit Span: μ7,72 [ds=2,98] vs μ10,14 [ds=3,10], U=865,00, p=0,00; Digit Symbol: μ5,36 …
Past and present work practices of European interventional cardiologists in the context of radiation protection of the eye lens—results of the EURALO…
2018
International audience; This paper investigates over five decades of work practices in interventional cardiology, with an emphasis on radiation protection. The analysis is based on data from more than 400 cardiologists from various European countries recruited for a EURALOC study and collected in the period from 2014 to 2016. Information on the types of procedures performed and their annual mean number, fluoroscopy time, access site choice, x-ray units and radiation protection means used was collected using an occupational questionnaire. Based on the specific European data, changes in each parameter have been analysed over decades, while country-specific data analysis has allowed us to dete…
Dimensional analysis of the upper airway in obstructive sleep apnoea syndrome patients treated with mandibular advancement device: A bi‐ and three‐di…
2020
BACKGROUND The efficiency of the mandibular advancement device (MAD) in patients with obstructive sleep apnoea syndrome (OSAS) has been demonstrated. Nevertheless, the behaviour of the upper airway once MAD is placed and titrated, and its correlation with the apnoea-hypopnoea index (AHI) is still under discussion. OBJECTIVES To analyse the morphological changes of the upper airway through a bi- and three-dimensional study and correlate it with the polysomnographic variable, AHI. METHODS Patients were recruited from two different hospitals for the treatment of OSAS with a custom-made MAD. A cone-beam computer tomography and a polysomnography were performed at baseline and once the MAD was ti…
Temporal Profile of Gene Induction After Venous Ischemia and Effects of Spreading Depression
2004
Occlusion of two adjacent cortical veins is followed by a widespread reduction of rCBF and the occurrence of small infarcts, which become larger if spreading depression (SD) occurs. The infarct matures over time with TUNEL-positive cells seen in the penumbra up to 4 days after vein occlusion. Caspase inhibition with zVAD.fmk reduces infarct size. Here, the time course of gene expression in the penumbra is compared to that induced by SD alone.
302 Hearing Abnormalities in Children with Fabry Disease: Data from FOS - the Fabry Outcome Survey
2005
Background: Fabry disease is an X-linked glycosphingolipid storage disorder due to a deficiency of the enzyme alpha-galactosidase A. Accumulation of substrate results in a progressive and life-threatening multisystemic disease. Early clinical manifestations include pain and gastrointestinal symptoms. Sensorineural hearing loss and vertigo are well-recognized features of the disorder, occurring in approximately 50% of adults with Fabry disease. We have investigated the audiological symptoms of Fabry disease in children using pure-tone and impedance audiometry. Methods: Symptom history was obtained using a standardized questionnaire from FOS − the Fabry Outcome Survey. Hearing was measured us…
