TRATAMENTO CIRÚRGICO DAS PTOSES PALPEBRAIS: PERSPECTIVAS OFTALMOLÓGICAS E ESTÉTICAS

 The correction of eyelid ptosis, whether for aesthetic or functional reasons, is a specialized area in ophthalmology that seeks to restore not only facial aesthetics, but also adequate visual function. This surgical process, often customized to meet each patient's unique needs, involves complex considerations from both an ophthalmological and aesthetic perspective. We will explore the importance of integrating these two aspects to ensure satisfactory results, addressing both demographic variations and the ophthalmological complexities involved in the treatment of eyelid ptosis. Objective: Understand the surgical techniques, perspectives and results achieved through the procedure. Conclusion: In conclusion, surgical treatment of eyelid ptosis represents a careful integration of ophthalmological and aesthetic considerations. The search for satisfactory results is not limited only to functional correction, but also aims to improve facial harmony and the patient's self-esteem.A correção das ptoses palpebrais, seja por motivos estéticos ou funcionais, é uma área especializada na oftalmologia que busca restabelecer não apenas a estética facial, mas também a função visual adequada.

High glucose levels abolish antiatherosclerotic benefits of ACE inhibition in alloxan-induced diabetes in rabbits

Renin-angiotensin system activation is recognized to play an important role in atherosclerosis. This study aimed to verify the antiatherosclerotic effects of ACE inhibition on an experimental model of diabetes and hypercholesterolemia. Diabetes was induced in New Zealand male rabbits with a single dose of alloxan (100 mg/kg, IV), and, according to plasma glucose levels obtained after 1 week, the animals were divided into 2 groups (>= 250 mg/dL or < 250 mg/dL). Each group was randomly assigned to receive or not quinapril (30 mg/d) added to a 0.5% cholesterol-enriched diet. Animals with high glucose levels at 1 week and that remained high after 12 weeks presented higher triglyceride levels (P < 0.02 versus basal). Those initially hyperglycemic but presenting < 250 mg/dL glucose at the end of study formed an additional group. Plasma ACE activity was lower in quinapril-treated animals (P < 0.01 versus untreated groups). However, aorta intima/media ratio and intima area were lower only in the subgroups of quinapril-treated animals with low glucose levels (P < 0.05). Our results support the hypothesis that high plasma glucose may abolish the anti atheroscl erotic effect of ACE inhibitors.Universidade Federal de São Paulo, Disciplina Cardiol, Dept Med, São Paulo, BrazilUniversidade Federal de São Paulo, Dept Pathol, São Paulo, BrazilUniversidade Federal de São Paulo, Disciplina Cardiol, Dept Med, São Paulo, BrazilUniversidade Federal de São Paulo, Dept Pathol, São Paulo, BrazilWeb of Scienc
