L’injection percutanée de cartilage sur le dorsum nasal chez le lapin

Abstract: Objective: To compare the long-term viability of percutaneously injected crushed auricular cartilage to surgically implanted cartilage in the rabbit. Methods: Auricular cartilage was harvested bilaterally in 10 New Zealand white rabbits. A 1 cm2 cartilage graft was harvested and implanted surgically on the upper nasal dorsum. The remaining cartilage was crushed and percutaneously injected on the lower nasal dorsum. Volume and mass of each graft were compared between pre-implantation and after 3 months of observation. A histological study was conducted to evaluate chondrocyte viability and degree of fibrosis on the grafts. Results: Mass and volume remained similar for surgically implanted cartilage grafts. Mass and volume diminished by an average of 47% and 40% respectively after 3 months for the injected crushed cartilage grafts. Chondrocyte viability was an average of 25% lower in the injected grafts. Conclusion: Cartilage injection is a promising technique that must be refined to increase long term chondrocyte viability. Developing an appropriate injection apparatus would improve this technique.

El objetivo de esta investigación es describir la calidad de vida y la calidad del sueño en los pacientes con diagnóstico de Síndrome de Apnea Hipoapnea del sueño, mediante el uso de un grupo de cuestionarios para obtener datos demográficos, la evaluación del grado de somnolencia diurna percibida, la percepción de la calidad del sueño y la percepción de la calidad de vida relacionada con la salud con encuestas en sus respectivas versiones validadas para Colombia.

Què saben els pares dels infants de 0-3 anys, sobre l'ús del rentat nasal i els inhaladors amb cambra?

Aquest estudi insisteix en la importància de l’educació sanitària dirigida als pares per tal d’assegurar l’eficàcia del tractament a administrar i consolidar els coneixements i habilitats del progenitors per tal de que aquests puguin dur a terme les tècniques requerides de forma adequada. Destacar la necessitat de conscienciar a tots els professionals de la salut, sobretot els que passen més temps amb els familiars, de la importància que té la seva competència com educador en l’àmbit de la salut. Evidenciar la importància de fer una avaluació continuada dels coneixements i les habilitats adquirides pels cuidadors principals, sobre com dur a terme les tècniques del rentat de nas i administració de la medicació inhalada amb cambra i mascareta, per detectar-ne els possibles errors i poder posar-hi mesures correctores per pal·liar-los. Constatar la utilitat de preguntar i esbrinar “in situ” què saben els progenitors sobre les tècniques a avaluar (rentat de nas i administració de la medicació inhalada amb cambra i mascareta), abans de donar qualsevol explicació o iniciar l’educació sanitària per detectar les necessitats específiques de cada pare o mare i poder individualitzar el procés educatiu

Objective Assessment of Internal Nasal Dimensions and Speech Resonance in Individuals With Repaired Unilateral Cleft Lip and Palate After Rhinoseptoplasty

The objective of the current study was to analyze the effects of rhinoseptoplasty on internal nasal dimensions and speech resonance of individuals with unilateral cleft lip and palate, estimated by acoustic rhinometry and nasometry, respectively. Twenty-one individuals (aged 15-46 years) with previously repaired unilateral cleft lip and palate were analyzed before (PRE), and 6 to 9 (POST1) and 12 to 18 months (POST2) after surgery. Acoustic rhinometry was used to measure the cross-sectional areas (CSAs) of segments corresponding to the nasal valve (CSA1), anterior portion (CSA2), and posterior portion (CSA3) of the lower turbinate, and the volumes at the nasal valve (V1) and turbinate (V2) regions at cleft and noncleft sides, before and after nasal decongestion with a topical vasoconstrictor. Nasometry was used to evaluate speech nasalance during the reading of a set of sentences containing nasal sounds and other devoid of nasal sounds. At the cleft side, before nasal decongestion, there was a significant increase (P < 0.05) in mean CSA1 and V1 values at POST1 and POST2 compared with PRE. After decongestion, increased values were also observed for CSA2 and V2 at POST2. No significant changes were observed at the noncleft side. Mean nasalance values at PRE, POST1, an POST2 were not different from each other in both oral and nasal sentences. The measurement of CSAs and volumes by acoustic rhinometry revealed that rhinoseptoplasty provided, in most cases analyzed, a significant increase in nasal patency, without concomitant changes in speech resonance, as estimated by nasalance assessment.

Nasal immunization of mice with Lactobacillus casei expressing the Pneumococcal Surface Protein A: induction of antibodies, complement deposition and partial protection against Streptococcus pneumoniae challenge

Strategies for the development of new vaccines against Streptococcus pneumoniae infections try to overcome problems such as serotype coverage and high costs, present in currently available vaccines. Formulations based on protein candidates that can induce protection in animal models have been pointed as good alternatives. Among them, the Pneumococcal Surface Protein A (PspA) plays an important role during systemic infection at least in part through the inhibition of complement deposition on the pneumococcal surface, a mechanism of evasion from the immune system. Antigen delivery systems based on live recombinant lactic acid bacteria (LAB) represents a promising strategy for mucosal vaccination, since they are generally regarded as safe bacteria able to elicit both systemic and mucosal immune responses. In this work, the N-terminal region of clade I PspA was constitutively expressed in Lactobacillus casei and the recombinant bacteria was tested as a mucosal vaccine in mice. Nasal immunization with L. casei-PspA 1 induced anti-PspA antibodies that were able to bind to pneumococcal strains carrying both clade 1 and clade 2 PspAs and to induce complement deposition on the surface of the bacteria. In addition, an increase in survival of immunized mice after a systemic challenge with a virulent pneumococcal strain was observed. (C) 2008 Elsevier Masson SAS. All rights reserved.

O espelho de Glatzel na avaliação da permeabilidade nasal em adultos

Introdução O espelho de Glatzel (EG) é correntemente utilizado em consultórios fonoaudiológicos para a avaliação rápida da permeabilidade nasal. O mesmo foi descrito inicialmente em 1898 por Zwaardemaker. Porém, estudos de validação inexistem na literatura. Este estudo teve por objetivos verificar a reprodutibilidade do EG e a correlação intra-sujeito entre área de condensação e percepção subjetiva de permeabilidade nasal. Material e Métodos Vinte e cinco sujeitos foram avaliados com o EG por cinco minutos consecutivos (475 medidas por sujeito); cada meia hora por quatro horas; cada dia no início da tarde, por cinco dias e toda a quinta-feira por cinco semanas consecutivas. Utilizou-se uma escala análoga visual para avaliar a percepção de respiração nos períodos de horas, dias e semanas. Resultados O coeficiente de correlação total (área direita mais esquerda) encontrado entre área de condensação e percepção subjetiva foi de r=0,04 (p=0,3761). No lado esquerdo foi de r=0,08 (p=0,0984) e no lado direito de r=0,05 (p=0,2862). Os coeficientes de variação unilaterais medianos foram menores que 15% e os totais menores que 12%, independente do intervalo de tempo entre teste e re-teste. Conclusão Não se evidenciou correlação significativa entre a percepção subjetiva e a área de condensação nasal. A variabilidade unilateral foi maior do que quando considerados os valores totais (direito mais esquerdo) e não houve diferença na variabilidade das medidas de área de condensação nasal nos diferentes momentos do tempo.
