INTRODUCTION: Hysterectomy is one of the most common gynecological procedures and may be performed either by vaginal approach, laparotomy or laparoscopy. Although total laparoscopic hysterectomy has multiple advantages, conflicting major complication rates have been previously reported. OBJECTIVES: To describe our experience performing TLH and to evaluate complication rates. MATERIAL AND METHODS: A retrospectiv...
A ingestão acidental de produtos cáusticos pelas crianças continua a ser um problema actual. Com o objectivo de conhecer a panorâmica dos últimos 8 anos, no Hospital Geral de Santo António (HGSA), os autores fizeram a revisão dos processos clínicos referentes às 88 crianças que deram entrada no Serviço de Urgência deste hospital, de Janeiro de 1988 a Dezembro de 1995, por ingestão de cáusticos e que motivou a r...
A relação entre Dor Abdominal Recorrente (DAR) na criança e a infecção por Helicobacter pylori (Hp) tem sido longamente debatida, mantendo-se ainda um assunto polémico.No sentido de investigar este problema avaliaram-se 35 crianças com DAR da Consulta Externa de Gastroenterologia Pediátrica do Hospital de S. João.Métodos: Os doentes incluídos no estudo efectuaram investigação clínica e analítica adequada a cada...
Transplant glomerulopathy is a sign of chronic kidney allograft damage. It has a distinct morphology and is associated with poor allograft survival. We aimed to assess the prevalence and clinic-pathologic features of transplant glomerulopathy, as well as determine the functional and histological implications of its severity. We performed a single-centre retrospective observational study during an eight-year per...
Hypokalaemia is a common clinical disorder, the cause of which can usually be determined by the patient's clinical history. Gitelman syndrome is an inherited tubulopathy that must be considered in some settings of hypokalaemia. We present the case of a 60-year-old male patient referred to our nephrology department for persistent hypokalaemia. Clinical history was positive for symptoms of orthostatic hypotension...
The ability to monitor fetal heart rate is vital during late pregnancy and labor in order to evaluate fetal well-being. Current monitoring practice is essentially based on external cardiotocography and, less frequently, during labor, invasive fetal scalp electrocardiography. Many current and envisaged applications could benefi t from simpler devices using a 3-lead ECG confi guration. We are designing a maternit...
Nanostructured copper-diamond composites can be tailored for thermal management applications at high temperature. A novel approach based on multiscale diamond dispersions is proposed for the production of this type of materials: a Cu-nDiamond composite produced by high-energy milling is used as a nanostructured matrix for further dispersion of micrometer sized diamond. The former offers strength and microstruct...
Pure tungsten and tantalum plates and tungsten–tantalum composites produced via mechanical alloying and spark plasma sintering were bombarded with He+ and D+ energetic ion beams and deuterium plasmas. The aim of this experiment is to study the effects caused by individual helium and deuterium exposures and to evidence that the modifications induced in the composites at different irradiation energies could be fo...
