Púrpura fulminante pós varicela

A púrpura fulminante é uma doença trombótica rara que pode ocorrer durante ou após uma infecção ou no contexto de deficiência congénita ou adquirida de proteína C ou S. Caracteriza-se pelo envolvimento cutâneo extenso, particularmente ao nível das extremidades distais, por vezes com atingimento concomitante de outros órgãos por coagulação intravascular disseminada. Apresenta-se o caso de uma criança do sexo mas...

Long-term mortality analysis in Parkinson's disease treated with deep brain sti...

Background. Few data have been published regarding long-term mortality in patients with Parkinson's disease treated with DBS. Methods. This study analyzed long-term mortality rates, causes, and correlates in PD patients treated with DBS. Results. 184 consecutive patients were included; mean follow-up was 50 months. Fifteen deaths occurred (total 8.15%, annual mortality rate 1.94%). Mean age at disease onset and...

All-optical routing with MZI-SOAs Switches

Wavelength Conversion with MZI-SOAs

Wavelength multicasting at 40Gb/s is demonstrated by all-optical multi-wavelength conversion based on a single MZI-SOA. Simultaneous ITU grid 200GHz spaced one-to-four conversion is achieved with negligible sensitivity difference among all the multicast channels. Furthermore, we propose some new all-optical applications enabled by this technology. ; Wavelength multicasting at 40Gb/s is demonstrated by all-opti...

The influence of ACE ID and ACTN3 R577X polymorphisms on lower-extremity functi...

Background We studied the influence of the ACE I/D and ACTN3 R577X polymorphisms (single or combined) on lower-extremity function in older women in response to high-speed power training. Methods One hundred and thirty-nine healthy older Caucasian women participated in this study (age: 65.5 ± 8.2 years, body mass: 67.0 ± 10.0 kg and height: 1.57 ± 0.06 m). Walking speed (S10) performance and functional capac...

Um sistema experimental de Near Video on Demand

This article describes the work done on the development of a Near Video on Demand system. The system is divided in several blocks, which were independently developed, although they are not autonomous. Thus, the main development effort wasfocused in the following subsystems: video channels coding (pseudo-dynamic encryption), video server and access controller, data transmission, bot...

Air quality assessment for Portugal

According to the Air Quality Framework Directive, air pollutant concentration levels have to be assessed and reported annually by each European Union member state, taking into consideration European air quality standards. Plans and programmes should be implemented in zones and agglomerations where pollutant concentrations exceed the limit and target values. The main objective of this study is to perform a long-...

Osteochondral transplantation using autografts from the upper tibio-fibular joi...

PURPOSE: Treatment of large cartilage lesions of the knee in weight-bearing areas is still a controversy and challenging topic. Autologous osteochondral mosaicplasty has proven to be a valid option for treatment but donor site morbidity with most frequently used autografts remains a source of concern. This study aims to assess clinical results and safety profile of autologous osteochondral graft from the upper ...

Assessment of rotatory laxity in anterior cruciate ligament-deficient knees usi...

PURPOSE: Objective evaluation of both antero-posterior translation and rotatory laxity of the knee remains a target to be accomplished. This is true for both preoperative planning and postoperative assessment of different ACL reconstruction emerging techniques. The ideal measurement tool should be simple, accurate and reproducible, while enabling to assess both ‘‘anatomy’’ and ‘‘function’’ during the same exami...
