Evaluation of facial esthetics in rehabilitated adults with complete unilateral cleft lip and palate

Objectives. The aim of this study was to evaluate the facial esthetics of White-Brazilian adults with complete unilateral cleft lip and palate (UCLP) rehabilitated at a single center. Design. 30 patients (13 females; 17 males; mean age of 24.0 years), rehabilitated at a single center, were photographed and evaluated by 25 examiners, 5 orthodontists, and 5 plastic surgeons dealing with oral clefts, 5 orthodontists and 5 plastic surgeons with no experience in the cleft treatment, and 5 laymen. Their facial profiles were classified into esthetically unpleasant, esthetically acceptable, and esthetically pleasant. Results. Orthodontists dealing with oral clefts classified the majority of the sample as esthetically pleasant. Plastic surgeons dealing with oral cleft, orthodontists, and plastic surgeons without experience with oral clefts classified most of the sample as esthetically acceptable. Laymen evaluation also considered the majority of the sample as esthetically acceptable. Conclusions. The facial profiles of rehabilitated adults with UCLP were classified mostly as esthetically acceptable, with variations among the categories of examiners. The examiners dealing with oral clefts gave higher scores to the facial esthetics when compared to professionals without experience in oral clefts and laypersons, probably due to their knowledge of the limitations involved in the rehabilitation process

Two important but almost never related beliefs

Engelmann believes in two general strong beliefs. On one side, Engelmann believes in probabilistic skepticism. That the existence has its maximum probability or there is no existence at all is not possible. The other probabilities of existence are always possible. On the other hand, instead of elements that constitute a beginning arrived at by an unknown division, the Gestalt theory begins with wholes or Gestalten. These Gestalten can be divided in parts but each part can be only a part of his specific Gestalt. The majority of probabilistic skeptics and the majority of Gestalt theory followers do not believe they can be together accepted. On the contrary Engelmann is a member of a small group that both beliefs occur simultaneously. Bibace`s questions were each answered by Engelmann. In some questions Engelmann harmonize with Bibace, in others they disagree.

WHAT THE STUDIES CONDUCTED IN BRAZIL REGARDING DIVIDEND POLICY REVEAL

This paper consists of a review of the literature about dividend policy in Brazil, focusing on the empirical studies conducted from 1990 to 2010 that were published in major Brazilian administration, accounting and finance journals and major conference proceedings on this subject. The analyzed sample comprised 39 studies using various methods and conducted in various periods. Based on the model of Harris and Raviv (1991), this paper grouped studies according to model type, and it found five main categories. We were able to find some tendencies, such as: dividend policy relevance in the Brazilian market; confirmation of existence of agency problems; conflicting findings regarding the clientele hypothesis; tax signaling in, and tax impact on, defining dividend policy; non-conflicting findings regarding key factors of dividend policy..

A Conservative Approach for Restoring Anterior Guidance: A Case Report

One of the most common dental problems in today's clinics is tooth wear, specifically when related to bruxism. In such cases, the esthetics of anterior teeth may be compromised when excessive wear to the incisal surfaces occurs. Anterior tooth wear resulting from parafunctional bruxism can be conservatively treated with the use of direct resin composite restorations. This restorative approach has the advantages of presenting good predictability, load resistance, acceptable longevity, preservation of healthy dental tissues, and lower cost when compared with indirect restorations. The use of resin composites to solve esthetic problems, however, requires skill and practice. Thus, the present article demonstrates a conservative approach for restoring the esthetics and function of worn anterior teeth with the aid of direct resin composite restorations and selective occlusal adjustment. CLINICAL SIGNIFICANCE A conservative approach to restore anterior teeth with excessive wear is possible with direct resin composites. (J Esthet Restor Dent 24:171-184, 2011)

Co-existence of t(6;13)(p21;q14.1) and trisomy 12 in chronic lymphocytic leukemia

We report a case of a 57-year-old man diagnosed with chronic lymphocytic leukemia (CLL) and presence of a rare t(6;13)(p21;q14.1) in association with an extra copy of chromosome 12. Classical cytogenetic analysis using the immunostimulatory combination of DSP30 and IL-2 showed the karyotype 47,XY,t(6;13)(p21;q14.1), +12 in 75% of the metaphase cells. Spectral karyotype analysis (SKY) confirmed the abnormality previously seen by G-banding. Additionally, interphase fluorescence in situ hybridization using an LSI CEP 12 probe performed on peripheral blood cells without any stimulant agent showed trisomy of chromosome 12 in 67% of analyzed cells (134/200). To the best of our knowledge, the association of t(6;13)(p21;q14.1) and +12 in CLL has never been described. The prognostic significance of these new findings in CLL remains to be elucidated. However, the patient has been followed up since 2009 without any therapeutic intervention and has so far remained stable.

On the existence of G-equivariant maps

Let G be a compact Lie group. Let X, Y be free G-spaces. In this paper, by using the numerical index i (X; R), under cohomological conditions on the spaces X and Y, we consider the question of the existence of G-equivariant maps f: X -> Y.

Existence and concentration of solutions for a class of biharmonic equations

Some superlinear fourth order elliptic equations are considered. A family of solutions is proved to exist and to concentrate at a point in the limit. The proof relies on variational methods and makes use of a weak version of the Ambrosetti-Rabinowitz condition. The existence and concentration of solutions are related to a suitable truncated equation. (C) 2012 Elsevier Inc. All rights reserved.

Existence of Solutions for Abstract Non-Autonomous Neutral Differential Equations

In this paper we discuss the existence of mild and classical solutions for a class of abstract non-autonomous neutral functional differential equations. An application to partial neutral differential equations is considered.

EXISTENCE OF SOLUTIONS FOR A FRACTIONAL NEUTRAL INTEGRO-DIFFERENTIAL EQUATION WITH UNBOUNDED DELAY

In this article, we study the existence of mild solutions for fractional neutral integro-differential equations with infinite delay.

SUFFICIENT CONDITIONS ON DIFFUSIVITY FOR THE EXISTENCE AND NONEXISTENCE OF STABLE EQUILIBRIA WITH NONLINEAR FLUX ON THE BOUNDARY

A reaction-diffusion equation with variable diffusivity and non-linear flux boundary condition is considered. The goal is to give sufficient conditions on the diffusivity function for nonexistence and also for existence of nonconstant stable stationary solutions. Applications are given for the main result of nonexistence.

Amplification of the flgE gene provides evidence for the existence of a Brazilian borreliosis

INTRODUCTION: The symptoms of Brazilian borreliosis resemble the clinical manifestations of Lyme disease (LD). However, there are differences between the two in terms of epidemiological and laboratory findings. Primers usually employed to diagnose LD have failed to detect Borrelia strains in Brazil. OBJECTIVE: We aimed to identify the Brazilian Borrelia using a conserved gene that synthesizes the flagellar hook (flgE) of Borrelia burgdorferi sensu lato. METHOD: Three patients presenting with erythema migrans and positive epidemiological histories were recruited for the study. Blood samples were collected, and the DNA was extracted by commercial kits. RESULTS: The gene flgE was amplified from DNA of all selected patients. Upon sequencing, these positive samples revealed 99% homology to B. burgdorferi flgE. CONCLUSION: These results support the existence of borreliosis in Brazil. However, it is unclear whether this borreliosis is caused by a genetically modified B. burgdorferi sensu stricto or by a new species of Borrelia spp.
