Impact of malocclusion, tooth loss and oral hygiene habits on quality of life i...

We aimed to assess the impact of malocclusion on oral health-related quality of life (OHRQoL) in a sample composed of adolescents, younger adults and adults seeking orthodontic treatment. Participants were consecutively enrolled from January 2019 to March 2020. The oral health impact profile (OHIP-14) was used to measure the OHRQoL. The index of complexity, outcome and need (ICON) was used to assess malocclusio...

Effects of Economic Recession on Elderly Patients’ Perceptions of Access to Hea...

BackgroundIn view of the current financial and demographic situation in Portugal, accessibility to health care may be affected, including the ability to adhere to medication. Objective To evaluate the perceived effects of the crisis on elderly patient’s access to medicines and medical care, and its implications on medicine-taking behaviour. Setting Community pharmacy. Method: A cross-sectional study was undertak...

Respiratory quotient estimations as additional prognostic tools in early septic...

Central venous-to-arterial carbon dioxide difference (PcvaCO2), and its correction by the arterial-to-venous oxygen content difference (PcvaCO2/CavO2) have been proposed as additional tools to evaluate tissue hypoxia. Since the relationship between pressure and content of CO2 (CCO2) might be affected by several factors, some authors advocate for the use of CcvaCO2/CavO2. The aim of the present study was to expl...

Diretivas Antecipadas da Vontade: A Propósito de Um Caso Clínico

Descreve-se o caso de uma mulher de 61 anos, com diagnóstico de neoplasia da mama em estadio IV. Na altura, recusou terapêutica. Recorre ao Serviço de Urgência, um ano após o diagnóstico, em mutismo, sendo que os exames complementares de diagnóstico revelaram uma lesão cerebral, interpretada como nova metástase. No seu processo clínico, tem uma diretiva antecipada de vontade. Este é um documento formal que expl...

Síndrome de Moyamoya e drepanocitose: a propósito de um caso clínico

A síndrome de moyamoya é uma entidade clínica rara, de etologia desconhecida, encontrando-se descrita em associação com várias patologias, entre as quais a drepanocitose. Os autores apresentam o caso de uma mulher de 28 anos com antecedentes de drepanocitose, dois episódios de acidente vascular cerebral e hemiparesia esquerda sequelar: recorre ao serviço de urgência por agravamento da hemiparesia esquerda, alte...

Direct Percutaneous Endoscopic Jejunostomy Using Single-Balloon Enteroscopy wit...

BACKGROUND: Direct percutaneous endoscopic jejunostomy (DPEJ) is a useful method to provide enteral nutrition to individuals when gastric feeding is not possible or contraindicated. The aim of this study was to analyze the efficacy and safety of DPEJ tube placement with the Gauderer-Ponsky technique by the pull method, using single-balloon enteroscopy (SBE) without fluoroscopy. METHODS: This is a retrospective ...

Central venous-to-arterial carbon dioxide difference and the effect of venous h...

Central venous-to-arterial carbon dioxide difference (PcvaCO2) has demonstrated its prognostic value in critically ill patients suffering from shock, and current expert recommendations advocate for further resuscitation interventions when PcvaCO2 is elevated. PcvaCO2 combination with arterial-venous oxygen content difference (PcvaCO2/CavO2) seems to enhance its performance when assessing anaerobic metabolism. H...

Galvanic Corrosion of Two Non Noble Dental Alloys

This study aims to evaluate the corrosion resistance of two nonnoble dental alloys, namely, the Wiron®88 (Ni–Cr–Mo) and the Remanium 2000+ (Co–Cr–Mo–W). A noble alloy, the V-Gnathos® Plus (AuPt) previously studied was also considered for the purpose of comparison. The study was conducted in artificial saliva, pH 7.1, at 37 °C, by cyclic and linear sweep voltammetry, electrochemical impedance spectroscopy and ...

The corrosion resistance of two non-noble alloys

Nickel-chromium and cobalt-chromium alloys are commonly used for crown and bridge castings. These non-noble dental alloys are much cheaper than noble dental alloys but on the other hand they have disadvantages related to their lower corrosion resistance and corrosion products (released ions), some of them recognized as toxic ions that may cause allergies and other oral pathologies. Therefore it is important to ...
