Ferrara intrastromal corneal ring segments for severe keratoconus
No full textPURPOSE: Intrastromal Ferrara ring segments were inserted in eyes with severe keratoconus to evaluate safety and efficacy of this procedure.METHODS: Intrastromal Ferrara ring segments were placed in 36 eyes of 35 patients with severe keratoconus, who were evaluated after 12 months of follow-up. All patients had highly disabling visual acuity, contact lens intolerance, and a previous indication for penetrating keratoplasty, Statistical analysis included preoperative and postoperative uncorrected visual acuity, best spectacle-corrected visual acuity, manifest refraction, anterior chamber depth, keratometry, and pachymetry.RESULTS: No patient had a loss of visual acuity. Uncorrected visual acuity improved in 28 eyes (77.78%) and best spectacle-corrected visual acuity improved in 29 eyes (80.56%). Spherical equivalent refraction decreased from -7.29 +/- 3.12 D to -4.80 +/- 3.04 D at 12 months after Ferrara intrastromal ring segment implantation. Corneal topography and ultrasound biomicroscopy showed corneal flattening, demonstrated by thinning of the central cornea and a reduction in anterior chamber depth. Segment decentration occurred in one eye (2.7%), asymmetric positioning of the segments in two eyes (5%), inadequate depth in two eyes (5%), migration of the segments in two eyes (5%), segment extrusion in five eyes (13.8%), conjunctivitis in one eye (2.7%), bacterial keratitis in one eye (2.7%), and hydrops in one eye (2.7%).CONCLUSIONS: With these early results, Ferrara intrastromal ring segments appear to be an alternative for the treatment of severe keratoconus.Univ Fed Sao Paulo, Paulista Sch Med, Dept Ophthalmol, BR-04023062 Sao Paulo, BrazilOsped San Gerardo, Dept Ophthalmol, Belo Horizonte, MG, BrazilUniv Fed Sao Paulo, Paulista Sch Med, Dept Ophthalmol, BR-04023062 Sao Paulo, BrazilWeb of Scienc
En torno al misterio de Dios: el pensamiento de Ricardo Ferrara
No full textResumen: Luego de presentar el índice de una obra colectiva internacional dedicada a Ricardo
Ferrara, el autor se detiene en la primera parte de este libro, en la cual tres artículos
estudian el pensamiento de Ferrara. El primero de ellos, de Carlos Galli, es una presentación
pormenorizada de la teología del autor. El segundo, de Víctor Fernández,
es un diálogo con Ferrara a partir de cuestiones ligadas a la gracia y la libertad. Finalmente,
el texto de Gerardo Söding, analiza el tema de la paternidad de Dios en la obra
de Ferrara.Abstract: The author introduces a collective and international book honoring Ricardo Ferrara.
He focuses on three papers: first, by Carlos Galli, is a detailed presentation of Ferrara’s
theology; second, by Víctor Fernández, studies Ferrara on issues concerning grace
and freedom. Finally, Gerardo Söding analyzes God’s parenthood within Ferrara’s
thought
Dermoscopy Insights Into Nevogenesis : 'Abtropfung' vs. 'Hochsteigerung'
No full textTwo concepts, the “Abtropfung” and the “Hochsteigerung,” have been used to explain the natural evolution of melanocytic nevi. The nevi in Figure 1 and Figure 2 are located on the respective backs of a 25- and a 20-year-old woman. By dermoscopy, the former first exhibited a central bluish pigmentation indicating pigmented cells in the papillary dermis (Figure 1A), while a significant color change toward brown occurred after 8 months (Figure 1B), reflecting the presence of pigment at the dermoepidermal junction. The nevus in Figure 2 reveals an opposite trend after 1 year of follow-up, with significant change of the color from brown (Figure 2A) to blue (Figure 2B). Whether this is caused by a real movement of cells (upward or downward) or by a different activation and/or maturation level of melanin-producing melanocytes remains speculative. Based on our observation, currently both concepts or the concept of “nevus activation” seem to be plausible to explain some steps in the evolution process of melanocytic nevi
New classification of melanocytic nevi based on dermoscopy
No full textThe lack of consensus among clinicians and pathologists, owing to the mixture of clinical and histopathologic features used to define the various melanocytic nevi, underscores the need for a better classification system for these benign lesions. Most dermoscopic patterns of melanocytic nevi correspond to specific histopathologic correlates and, based on this, we recently introduced a new classification system of melanocytic nevi that is directed at clinicians dealing with early diagnosis of melanoma, as well at pathologists, in order to promote better communication between these different specialists. © 2008 Expert Reviews Ltd
