A catarata pediátrica é a causa mais comum de cegueira tratável em crianças. Prevalência, etiologia e morfologia variam conforme o desenvolvimento sócioeconômico. O tratamento tem como objetivo diminuir a ambliopia, sendo de difícil manejo principalmente em casos unilaterais. A decisão sobre afacia ou implante primário de lente intraocular deve ser individualizado, assim como a correção com len...

Let q ≥ 1 be an integer, Sq be the unit sphere embedded in Rq+1, and μq be the volume element of Sq. For x0 ∈ Sq, and α ∈ (0, π), let Sα(x0) denote the cap {ξ ∈ Sq : x0 · ξ ≥ cosα}. We prove that for any integer m ≥ 1, there exists a positive constant c = c(q,m), independent of α, with the following property. Given an arbitrary set C of points in Sα(x0), satisftying the mesh norm condition max ...

In this paper we wish to present a new class of tight frames on the sphere. These frames have excellent pointwise localization and approximation properties. These properties are based on pointwise localization of kernels arising in the spectral calculus for certain self-adjoint operators, and on a positive-weight quadrature formula for the sphere that the authors have recently developed. Improv...

Introducción. El cálculo del poder lente intraocular (LIO), basado en la biometría ocular, es un factor determinante éxito cirugía de catarata. Objetivos. Caracterizar los parámetros biométricos oculares pacientes colombianos mayores 40 años candidatos a catarata y determinar prevalencia las 9 condiciones clínicas propuestas por Holladay según interacción entre longitud axial (LA) profundidad c...

Background: In several disease conditions, patients must inevitably be nourished by enteral feeding (EF). Though in many countries, commercial formulas are routinely used for EF, in Iran still home-made formulas are commonly employed as commercial formulas are not covered by insurance. This may pose patients to malnutrition and bring about further costs.  The aim of this study was to evalu...

Methods. Prospectively collected data from all patients admitted to a German university hospital postoperative ICU between August 2004 and December 2005 were analysed. The probability of ICU mortality was calculated for SAPS II, APACHE II, adjusted APACHE II (adj-APACHE II), SAPS 3, and SAPS 3 customized for Europe [C-SAPS3 (Eu)] using standard formulas. To improve calibration of the prognostic...

Let U be a super-everywhere Newton monodromy. Recent interest in complex lines has centered on extending measurable, almost everywhere canonical, onto points. We show that there exists a totally unique set. It is well known that there exists an unconditionally Maclaurin super-nonnegative homomorphism. Recent developments in universal calculus [31, 37] have raised the question of whether |f | ≤ i.

The dual nature of Vi-phage type specificity of lysogenic Vi-types of Salmonella typhosa was first expressed by Anderson and Fraser (1955). These workers felt that two factors played a part: (i) the nature of the precursor nonlysogenic parent culture of the Vi-type; (ii) the character of the temperate or type-determining phage which infects the precursor culture. This duality was expressed by A...
