CHANGES IN THE TEAR PROTEIN PATTERNS OF DIABETIC PATIENTS USING TWO-DIMENSIONAL ELECTROPHORESIS.

2000

Four to five million Germans suffer from diabetes mellitus, and worldwide there are about 100 million people that suffer with the disease. In diabetic patients, dry eye and other ocular surface diseases occur more often than in healthy subjects. Very little is known about the alterations in tears caused by diabetes mellitus, or its influence on the pathogenesis of e.g., the dry eye disease. Recent studies from our group showed that there are differences in the one-dimensional electrophoretic tear protein separations between diabetic patients and healthy volunteers.1,2 The aim of this study is to analyze the tear protein patterns of patients suffering from diabetes (DIA) (Fig.l), and to comp…

Changes in the Tear Protein Patterns of Diabetic Patients Using Two-Dimensional Electrophoresis

Platelet Cut-Off For Anticoagulant Therapy In Cancer Patients With Venous Thromboembolism and Thrombocytopenia: An Expert Opinion Based On RAND/UCLA …

2013

Abstract Introduction Cancer-related Venous Thromboembolism (VTE) requires treatment with Low Molecular Weight Heparin (LMWH), which is more effective and safer than warfarin; however, the risk of major hemorrhage still remains clinically relevant (up to 5%). This rate is even higher in case of impaired hemostasis, such as during thrombocytopenia (due to myelosuppression or chemo-therapy) where the bleeding risk is directly related to the platelet count level. At the present, the best management of adult patients with acute or non-acute cancer-related VTE during thrombocytopenia is uncertain. Objective To develop a consensus about the platelet cut-off for a safe LMWH administration in cance…

Effects of a Vibro-Tactile P300 Based Brain-Computer Interface on the Coma Recovery Scale-Revised in Patients With Disorders of Consciousness

2020

Persons diagnosed with disorders of consciousness (DOC) typically suffer from motor and cognitive disabilities. Recent research has shown that non-invasive brain-computer interface (BCI) technology could help assess these patients’ cognitive functions and command following abilities. 20 DOC patients participated in the study and performed 10 vibro-tactile P300 BCI sessions over 10 days with 8–12 runs each day. Vibrotactile tactors were placed on the each patient’s left and right wrists and one foot. Patients were instructed, via earbuds, to concentrate and silently count vibrotactile pulses on either their left or right wrist that presented a target stimulus and to ignore …

Locking Y Lateral Canthopexy as a Treatment for Dry Eye Disease Caused by Eyelid Malposition

2020

PURPOSE The signs and symptoms of dry eye disease (DED) can affect the quality of life of patients. This study analyzes whether locking Y lateral canthopexy improves patients' quality of life and in what way it does so (based on the ocular surface disease index questionnaire) and DED signs (measured by the fluorescein breakup time, tear osmolarity, Schirmer test, and corneal staining) in patients with DED caused by a eyelid malposition or impaired blink dynamics. METHODS This was a case-control study. Forty eyes of 20 patients with DED and lateral canthal disinsertion examined at the University Hospital La Ribera during a 1-year period from November 2016 to November 2017. The 40 eyes were d…

Evaluating resurfacing modalities in aesthetics.

2022

Abstract Skin resurfacing for cutaneous rejuvenation has evolved with the development of a plethora of nonsurgical and minimally invasive modalities. We have highlighted the advances in laser therapy, chemical peels, radiofrequency, microneedling, and platelet-rich plasma therapy. We have also included studies providing head-to-head comparisons between procedures and discussed relevant debates in the field. We have examined additionally combination treatments and resurfacing in acne scars, melasma, and skin of color.

Use of digital displays and ocular surface alterations: A review.

2020

Digital display use has been accepted to be implicated as a contributing factor for dry eye disease (DED). Abnormal blinking during computer operation, including a reduced blink rate and an incomplete eyelid closure, increased palpebral fissure as consequence of high visualization angles, and meibomian gland dysfunction associated to long-term display use, are behind the increased prevalence of dry eye signs and symptoms found in digital display users. Previous research reveals significant reductions in tear volume and stability, alterations in tear film composition, including increased osmolarity, inflammatory cytokines, oxidative stress markers and reduced mucin secretion, eyelid abnormal…

The "sandwich technique" for iris-fixated phakic intraocular lens implantation.

2006

ABSTRACT PURPOSE: To describe a new technique of implantation of the Artisan/Verisyse phakic intraocular lens (PIOL). METHODS: After PIOL insertion into the anterior chamber, a bolus of a high viscosity ophthalmic viseosurgical device (OVD) is placed over the optic, separating it widely from the endothelium. RESULTS: The technique decreases the chance of endothelial damage during enclavation. CONCLUSIONS: A bolus of a high viscosity OVD placed on the anterior surface of the Artisan/Verisyse PIOL may make enclavation safer. [J Refract Surg. 2006;22:96-98.]

Anterior chamber depth measurement in teenagers. Comparison of two techniques

2013

Purpose: The aim of this study is to determine the anterior chamber depth (ACD) in teenagers using two different devices: partial coherence interferometry IOLMaster (Carl Zeiss Meditec) and anterior segment optical coherence tomography (Visante TM OCT, Carl Zeiss Meditec) and to evaluate the degree of agreement between ACD measurements carried out by both instruments. Methods: In this prospective study 68 eyes of 34 emmetropic Caucasic patients (18 girls and 16 boys) were analysed. ACD was measured from the anterior corneal surface to anterior surface of the crystalline lens. For each age the ACD size was calculated and the difference between IOLMaster and Visante-OCT measurements was analy…
