New geochemical and isotopic constraints on the genesis of the Oliveira Azeméis...

The Porto-Tomar Shear Zone (PTSZ) is a very important tectonic structure that separates, in central-western Portugal, two of the major tectonic units of the Iberian Variscan Chain: the Ossa-Morena Zone, to the west, and the Central Iberian Zone, to the east. The Oliveira de Azeméis area lies in the northern sector of the PTZC and it is characterized by the occurrence of strongly deformed granitoids. Country roc...

Sustained relief of obstructive symptoms for the remaining life of patients fol...

BACKGROUND: self-expanding metal stents are currently being used as a definitive palliative treatment for malignant colorectal obstruction in patients with incurable disease. Few studies have followed large numbers of patients from stent placement until death, and those few have reported conflicting results in the long-term clinical outcome data. AIMS: this study evaluated the clinical effectiveness of stent p...

A novel de novo deletion of chromosome 7 [46,XX,del(7)(p14.2 p15.1)] in a child...

The phenotype and severity of symptoms associated with deletions on chromosome 7 are directly proportional to the size of the deleted segment. Distal and interstitial deletions have been described in 40 cases. In this report the authors aim to report a child with a novel de novo interstitial deletion on chromosome 7, with the following karyotype: 46,XX,del(7)(p14.2 p15.1). We described a female, born at 38 week...

Hypertrophic pyloric stenosis: tips and tricks for ultrasound diagnosis

We describe a systematic approach to the ultrasound (US) examination of the antropyloric region in children. US is the modality of choice for the diagnosis of hypertrophic pyloric stenosis (HPS). The imaging features of the normal pylorus and the diagnostic findings in HPS are reviewed and illustrated in this pictorial essay. Common difficulties in performing the examination and tips to help overcome them will ...

Lifestyle Habits and Cardiovascular Risk Factors in a Young Population

Although CVD is mostly present in adult life, atherosclerosis starts in childhood. Health promotion and cardiovascular prevention strategies can generate health gains and, if implemented in childhood, those gains will be superior. In pathologies with multifactorial etiology like CVD, the preventive approach should be addressed to risk factors, specially the modifiable related to unhealthy lifestyle habits. The ...

Results of the routine use of 4F catheters for diagnostic catheterization in a ...

INTRODUCTION: Complications at the site of vascular access are the most common adverse events in cardiac catheterization. The use of small gauge catheters may reduce this risk and allow earlier ambulation, the main disadvantage according to some authors being inferior image quality. The aim of our study was to evaluate the safety and image quality of 4 French diagnostic catheters. METHODS: We performed a retro...

BACKGROUND: In 2006, bronchiolitis due to adenovirus nosocomial infections resulted in the closure of a pediatric department in northern Portugal. OBJECTIVES: To determine the etiology of bronchiolitis in northern Portugal. STUDY DESIGN: It was a prospective multicenter study on the etiology of bronchiolitis during the respiratory syncytial virus (RSV) season (November-April). Children < or = 24 months of age...
