A biomaterial helps to improve the quality of life and longevity of humans. Over the last decades it has become clear that the demand for biomaterials has increased rapidly due to the aging population that occurs in practically all the countries of the world, with the elderly being at higher risk of hard tissue insufficiency. Biological and mechanical biocompatibility of metal biomaterials requires much improvement. It is sought to achieve a longer shelf life of the implant biomaterial or that it lasts until the end of life without failures or need for revision surgery. Biomaterials must meet several criteria, such as excellent biocompatibility, adequate mechanical compatibility, high corrosion and wear resistance. The present work aims to perform a description of biomaterials and some properties for their choice, evidencing some characteristics of the biomaterial of titanium and its alloys.Thus, the implants are expected to act much longer or to the end of life without flaws or revision surgeries. Thus, the development of Volume 14-Issue 3
A case is reported of an eight-month-old female patient who had traditional uvulectomy for sore throat complicated by Grisel's syndrome. She was admitted into the hospital one week after uvulectomy with Torticolis. Grisel's syndrome is a nontraumatic atlantoaxial subluxation, usually secondary of an infection or an inflammation at the head and neck area, or after surgery in the same area. Patients typically suffer from painful torticollis. Diagnosis of Grisel's syndrome is largely based on suspicion of the patient who has recently undergone surgery or has a history of an infection in head and neck area. Physical examination and imaging techniques assist in diagnosis. Thus, clinicians should be aware of acute nontraumatic torticollis if patient had a recent surgery in the head or neck area or undergone an upper respiratory tract infection. In this paper, a case of an eight-month-old female patient who had Grisel's syndrome after uvulectomy is discussed. This case is reported to highlight this neurogical threatening complication following traditional uvulectomy as well as highlighting the unnecessary morbidity and mortality associated with this persisting mode of treatment in Africa.
IntroductionL'exacerbation d'asthme est un phénomène paroxystique qui peut mettre en jeu le pronostic vital. Le but de l’étude est d’évaluer le profil épidémiologique et les modalités de prise en charge de l'exacerbation d'asthme chez les enfants âgés de 2 à 15 ans dans l'unité de pneumoallergologie pédiatrique de l'hôpital d'enfants de Rabat au Maroc.MéthodesIl s'agit d'une étude rétrospective qui a concerné 1461 enfants hospitalisés pour exacerbation d'asthme modérée à sévère durant une période d'un an allant de décembre 2011 à novembre 2012, les exacerbations légères étant traitées en ambulatoire.RésultatsLes hospitalisations pour exacerbation d'asthme chez les enfants ont représenté 34% de l'ensemble des hospitalisations avec trois pics en mai, septembre et décembre. L’âge moyen de survenue était de 3 ans et demi avec une prédominance masculine nette. L'exacerbation d'asthme était inaugurale dans 22% des cas. Les infections respiratoires virales dominaient les facteurs déclenchants des exacerbations d'asthme. Le séjour hospitalier était en moyenne de 3 jours. Un transfert en réanimation a été nécessaire dans 2% des cas. L’évolution sous traitement a toujours été favorable et la mortalité a été nulle.ConclusionLa prévalence des hospitalisations pour exacerbation d'asthme suit un profil saisonnier lié aux effets environnementaux. La plupart de ces hospitalisations pourraient cependant être évitées grâce à un meilleur contrôle de l'asthme et à l'amélioration de l’éducation thérapeutique de l'enfant asthmatique et de son entourage.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
