Long time remodeling during retinal degeneration evaluated by optical coherence tomography, immunocytochemistry and fundus autofluorescence.

Purpose: To characterize the relationship between fundus autofluorescence (FAF), Optical Coherence Tomography (OCT) and immunohistochemistry (IHC) over the course of chronic retinal degeneration in the P23H rat.

Methods: Homozygous albino P23H rats, Sprague-Dawley (SD) rats as controls and pigmented Long Evans (LE) rats were used. A Spectralis HRA OCT system was used for scanning laser ophthalmoscopy (SLO) imaging OCT and angiography.

Correlation between SD-OCT, immunocytochemistry and functional findings in an animal model of retinal degeneration.

Purpose: The P23H rhodopsin mutation is an autosomal dominant cause of retinitis pigmentosa (RP). The degeneration can be tracked using different anatomical and functional methods. In our case, we evaluated the anatomical changes using Spectral-Domain Optical Coherence Tomography (SD-OCT) and correlated the findings with retinal thickness values determined by immunocytochemistry.

[Methodology for evaluation of malignancy screening in surgical thyroid gland disease].

Introduction: We review a methodology for detection of malignancy in thyroid gland surgery, comparing clinical exploration, ultrasonography, gammagraphy, fine-needle aspiration (FNA) and extemporaneous biopsy with the definitive pathological results.

Material And Methods: We carried out a retrospective study on a sample of 433 (N=433) patients who had been intervened due to thyroid gland disease at the same ENT centre between 1999 and 2004. We collected information focusing on the characteristics of cervical exploration, ultrasonography, gammagraphy, FNA, extemporaneous biopsy and definitive pathological results.

[Laryngeal paraganglioma: diagnosis and treatment. A propos of a case].

Paragangliomas of the larynx (LPG) are unusual neuroendocrine tumors that are seen as a vascular submucosal mass, with a female predilection. We add another case of LPG to the 77 previously reported in the literature. We present the clinical, radiologic, and surgical features of a supraglottic LPG seen in a 40-year-old woman with a 8-month history of slowly progressive hoarseness.
