Raquitismo

O que é o Raquitismo?

O raquitismo é o amolecimento e o enfraquecimento dos ossos nas crianças, geralmente devido a uma deficiência de vitamina D extrema e prolongada.

A vitamina D promove a absorção de cálcio e fósforo do trato gastrointestinal. Uma deficiência de vitamina D torna difícil manter níveis adequados de cálcio e fósforo nos ossos, o que pode causar raquitismo.

Embora os efeitos às vezes sejam irreversíveis, a maioria dos tipos de raquitismo pode ser prevenida garantindo que a criança tenha vitamina D suficiente em sua dieta e tenha exposição suficiente à luz do sol.

A adição de vitamina D ou cálcio à dieta geralmente corrige os problemas ósseos associados ao raquitismo. Quando o raquitismo é devido a outro problema médico subjacente, seu filho pode precisar de medicamentos adicionais ou outro tratamento. Algumas deformidades esqueléticas causadas pelo raquitismo podem exigir cirurgia corretiva.

O raquitismo em adultos é conhecido como osteomalácia ou ossos moles.

O raquitismo era comum no passado, mas desapareceu principalmente no mundo ocidental no início do século 20, depois de alimentos como margarina e cereais serem fortificados com vitamina D.

Sintomas

Sinais e sintomas de raquitismo podem incluir:

Crescimento atrasado
Dor na espinha, pelve e pernas
Fraqueza muscular

Como o raquitismo suaviza as placas de crescimento nas extremidades dos ossos de uma criança, ela pode causar deformidades esqueléticas como:

Pernas curvadas ou joelhos
Polegas e tornozelos espessados
Projeção de mama

Causas

Seu corpo precisa de vitamina D para absorver cálcio e fósforo dos alimentos. O raquitismo pode ocorrer se o corpo do seu filho não tiver vitamina D suficiente ou se o seu corpo tiver problemas para usar a vitamina D adequadamente. Ocasionalmente, não obter cálcio suficiente ou falta de cálcio e vitamina D pode causar raquitismo.

Existem várias causas de raquitismo. Uma deficiência nutricional relacionada à falta de vitamina D, cálcio ou fosfato, provoca raquitismo mais comumente. Os três tipos de raquitismo são nutricionais, hipofosfatêmicos e renais, e os três são atribuíveis a deficiências nutricionais.

O raquitismo é um abrandamento ou enfraquecimento dos ossos. A causa da doença foi desconhecida há séculos e já era uma doença comum. Os cientistas na década de 1920 conseguiram identificar o que causa raquitismo e o número de ocorrências foi reduzido. Isso mudou desde então.

Falta de vitamina D

As crianças que não recebem bastante vitamina D dessas duas fontes podem desenvolver uma deficiência:

Luz solar. Sua pele produz vitamina D quando exposta à luz solar. Mas crianças em países desenvolvidos tendem a gastar menos tempo ao ar livre. Eles também são mais propensos a usar protetor solar, o que bloqueia os raios que desencadeiam a produção de vitamina D da pele.

Comida. Óleos de peixe, peixe gordo e gemas de ovo contêm vitamina D. A vitamina D também foi adicionada a alguns alimentos, como leite, cereais e alguns sucos de frutas.

Problemas com a absorção

Algumas crianças nascem ou desenvolvem condições médicas que afetam a forma como seus corpos absorvem a vitamina D.

Alguns exemplos incluem:

Doença celíaca
Doença inflamatória intestinal
Fibrose cística
Problemas renais

Complicações

Não tratado, o raquitismo pode levar a:

Falha em crescer
Espinha anormalmente curvada
Deformidades esqueléticas
Defeitos dentários
Convulsões

Como o raquitismo é tratado?

O tratamento para raquitismo concentra-se na substituição da vitamina ou mineral em falta no organismo. Isso eliminará a maioria dos sintomas associados ao raquitismo. Se o seu filho tiver uma deficiência de vitamina D, seu médico provavelmente irá querer que eles aumentem sua exposição à luz solar, se possível.

Também os encorajará a consumir produtos alimentares com alto teor de vitamina D, como peixes, fígado, leite e ovos.

Os suplementos de cálcio e vitamina D também podem ser utilizados para tratar raquitismo. Pergunte ao seu médico sobre a dosagem correta, pois pode variar de acordo com o tamanho do seu filho. Muita vitamina D ou cálcio pode ser inseguro.

Se as deformidades esqueléticas estiverem presentes, seu filho pode precisar de aparelhos para posicionar seus ossos corretamente à medida que crescem. Em casos graves, seu filho pode precisar de cirurgia corretiva.

Para o raquitismo hereditário, é necessária uma combinação de suplementos de fosfato e níveis elevados de uma forma especial de vitamina D para tratar a doença.

O que se pode esperar após o tratamento para o raquitismo?

Aumentar os níveis de vitamina D, cálcio e fosfato ajudará a corrigir a desordem. A maioria das crianças com raquitismo vê melhorias em cerca de uma semana.

As deformidades esqueléticas geralmente melhorarão ou desaparecerão ao longo do tempo se o raquitismo for corrigido enquanto a criança ainda for jovem. No entanto, as deformidades esqueléticas podem tornar-se permanentes se a desordem não for tratada durante o período de crescimento da criança.

Prevenção de raquitismo

Os raquitismos podem ser facilmente evitados comendo uma dieta que inclui vitamina D e cálcio, passando algum tempo na luz solar e, se necessário, tomando suplementos de vitamina D.

QUESTION 1 You are managing a SharePoint farm in an Active Directory Domain Services (AD DS) domain. You need to configure a service account to use domain credentials. What should you do first? A. Configure the service account to use a domain user account. B. Register the domain credentials in the Farm Administrators group. C. Configure the service account to use a local user account. D. Register the domain credentials as a SharePoint managed account. Correct Answer: D Explanation QUESTION 2 A company named Contoso, Ltd. has a SharePoint farm. The farm has one Search service application configured. The Search service application contains five crawl databases, all of which contain content. Contoso plans to crawl knowledge base content from its partner company Litware, Inc. The knowledge base content must be stored in a dedicated crawl database. You need to configure crawling. What should you do? A. Add a crawl database that contains the Litware knowledge base to the existing Search service application. B. Provision a new Search service application. Configure the service application to crawl the Litware knowledge base content. C. Set the MaxCrawlDatabase parameter to 6. D. Create a dedicated Microsoft SQL Server instance for the Litware crawl database. Correct Answer: B Explanation Explanation/Reference: The maximum number of crawl databases is 5 per Search service application so we need another Search service application. This maximum limit is increased to 15 with an Office 2013 update but the question doesn't mention that this update is installed so we have to assume the question was written before the update was released. QUESTION 3 A company uses SharePoint 2013 Server as its intranet portal. The Marketing department publishes many news articles, press releases, and corporate communications to the intranet home page. You need to ensure that the Marketing department pages do not impact intranet performance. Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.) A. In Central Administration, set up a User Policy for the Super User and Super Reader accounts. B. Configure IIS to use the Super User and Super Reader accounts for caching. C. Use the Farm Configuration Wizard to configure the Super User and Super Reader accounts. D. Use Windows PowerShell to add the Super User and Super Reader accounts. Correct Answer: AD Explanation Explanation/Reference: A: The way to correct this problem is to first create two normal user accounts in AD. These are not service accounts. You could call them domain\superuser and domain\superreader, but of course that's up to you. The domain\superuser account needs to have a User Policy set for that gives it Full Control to the entire web application. D: If you are using any type of claims based authentication you will need to use Windows PowerShell. And Windows PowerShell is the hipper more modern and sustainable option anyway. If you are using classic mode authentication run the following cmdlets on one of your SharePoint servers: $w = Get-SPWebApplication "http:///" $w.Properties["portalsuperuseraccount"] = "domain\superuser" $w.Properties["portalsuperreaderaccount"] = "domain\superreader" $w.Update() If you are using claims based authentication run these cmdlets on one of your SharePoint servers: $w = Get-SPWebApplication "http:///" $w.Properties["portalsuperuseraccount"] = "i:0#.w|domain\superuser" $w.Properties["portalsuperreaderaccount"] = "i:0#.w|domain\superreader" $w.Update() Note: * If you have a SharePoint Publishing site and you check the event viewer every once in a while you might see the https://www.pass4itsure.com/70-331.html following warning in there: Object Cache: The super user account utilized by the cache is not configured. This can increase the number of cache misses, which causes the page requests to consume unneccesary system resources. To configure the account use the following command 'stsadm -o setproperty -propertynameportalsuperuseraccount -propertyvalue account -urlwebappurl'. The account should be any account that has Full Control access to the SharePoint databases but is not an application pool account. Additional Data: Current default super user account: SHAREPOINT\system This means that the cache accounts for your web application aren't properly set and that there will be a lot of cache misses. If a cache miss occurs the page the user requested will have to be build up from scratch again. Files and information will be retrieved from the database and the file system and the page will be rendered. This means an extra hit on your SharePoint and database servers and a slower page load for your end user. Reference: Resolving "The super user account utilized by the cache is not configured." QUESTION 4 You are managing a SharePoint farm. Diagnostic logs are rapidly consuming disk space. You need to minimize the amount of log data written to the disk. Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.) A. Set the log event level to Information. B. Set the log event level to Verbose. C. Set the log trace level to Medium. D. Set the log trace level to Verbose. E. Set the log event level to Warning. F. Set the log trace level to Monitorable. Correct Answer: EF Explanation Explanation/Reference: E: Event Levels Warning, Level ID 50 Information, Level ID: 80 Verbose, Level ID: 100 F: Trace levels: Monitorable: 15 Medium: 50 Verbose: 100 Note: When using the Unified Logging System (ULS) APIs to define events or trace logs, one of the values you must supply is the ULS level. Levels are settings that indicate the severity of an event or trace and are also used for throttling, to prevent repetitive information from flooding the log files. Reference: Trace and Event Log Severity Levels QUESTION 5 A company's SharePoint environment contains three web applications. The root site collections of the web applications host the company intranet site, My Sites, and a Document Center. SharePoint is configured to restrict the default file types, which prevents users from uploading Microsoft Outlook Personal Folder (.pst) files. The company plans to require employees to maintain copies of their .pst files in their My Site libraries. You need to ensure that employees can upload .pst files to My Site libraries. In which location should you remove .pst files https://www.pass4itsure.com/70-342.html from the blocked file types? A. The File Types area of the Search service application section of Central Administration B. The General Security page in the site settings for the site collection C. The Blocked File Types page in the site settings for the site collection D. The General Security section of the Security page of Central Administration Correct Answer: D Explanation
