1. Scanning electron microscopy of panitumumab-induced eyelash and hair alterations - Pili canaliculi
Abstract Panitumumab is a monoclonal antibody against the epidermal growth factor receptor used in metastatic colorectal cancer; in addition to tumor cells, it acts on epidermal keratinocytes and on the outer root sheath and presents skin toxicity in up to 90% of cases. A scanning electron microscope was used to examine the eyelashes and hairs of a 65-year-o

4. Otoprotection Mechanisms Against Oxidative Stress Caused by Cisplatin
Abstract Introduction Cisplatin damages the auditory system and is related to the generation of free radicals. Glutathione peroxidase is an endogenous free radicals remover. Objective To investigate the mechanisms involved in otoprotection by N-acetylcys- teine through the expression of glutathione peroxidase in outer hair cells from rats treated with ci

7. The Study of Otoacoustic Emissions and the Suppression of Otoacoustic Emissions in Subjects with Tinnitus and Normal Hearing: An Insight to Tinnitus Etiology
Introduction Analysis of the suppression effect is a simple method to evaluate cochlear status and central auditory mechanisms and, more specifically, the medial olivocochlear system. This structure may be involved in the generation of mechanisms that cause tinnitus and in the pathophysiology of tinnitus in patients with tinnitus and n

8. Vitiligo - Part 2 - classification, histopathology and treatment
In an unprecedented effort in the field of vitiligo, a global consensus resulted on a suggested new classification protocol for the disease. The main histopathological finding in vitiligo is the total absence of functioning melanocytes in the lesions, while the inflammatory cells most commonly found on the edges of the lesions are CD4+ and CD8+ T lymphocytes

10. TOXICITY OF AN ORGANOPHOSPHATE PESTICIDE IN THE PERIPHERAL AUDITORY SYSTEM: ANATOMIC AND FUNCTIONAL STUDY / TOXICIDADE DE AGROTÓXICO ORGANOFOSFORADO NO SISTEMA AUDITIVO PERIFÉRICO DE COBAIAS: ESTUDO ANATÔMICO E FUNCIONAL
The organophosphate pesticides are widely used in agriculture, and the widespread application of these agents, without the appropriate use of bio-security measures, has contributed to environmental degradation and the increased incidence of occupational poisoning, becoming one of the main public health problems in rural areas. Studies show that the ototoxic

12. Ensaio clínico randomizado para avaliação do efeito otoprotetor do extrato de Ginkgo Biloba, por meio das emissões otoacústicas por produto de distorção, em pacientes sob tratamento com cisplatina
The ototoxicity is an alteration caused by drugs that compromises the auditory and vestibular functions. The cisplatin (CDDP) is a potent antineoplastic agent used for the treatment of cancer in both adults and children although it has several side effects. The cisplatin ototoxicity is a dose-limiting condition. Current opinion is that cisplatin ototoxicity
