An Unexpected Infection in a Venous Leg Ulcer: a Case Report

Providencia rettgeri is a Gram-negative bacillus that is most usually seen in urinary tract infections. Skin and soft tissue infections with P rettgeri are rare and there few case reports described in the literature. A 43-yearold woman presented to the emergency department with a leg ulcer of 3 months duration. Microbiological results isolated P rettgeri and Pseudomonas aeruginosa. She underwent surgical debrid...

Transcranial Direct Current Stimulation as an Add-on Treatment to Cognitive-Beh...

Background: Major Depressive Disorder (MDD) affects more than 264 million people worldwide. Current treatments include the use of psychotherapy and/or drugs, however ~30% of patients either do not respond to these treatments, or do not tolerate the side effects associated to the use of pharmacological interventions. Thus, it is important to study non-pharmacological interventions targeting mechanisms not direct...

Implantable Cardioverter-Defibrillators in Trials of Drug Therapy for Heart Fai...

BACKGROUND Medical therapy for heart failure with reduced ejection fraction evolved since trials validated the use of implantable cardioverter-defibrillators (ICDs). We sought to evaluate the performance of ICDs in reducing mortality in the era of modern medical therapy by means of a systematic review and meta-analysis of contemporary randomized clinical trials of drug therapy for heart failure with reduced eje...

Phenotypic Analysis of Urothelial Exfoliated Cells in Bladder Cancer via Microf...

Bladder cancer is the most common malignancy of the urinary tract, having one of the highest recurrence rates and progression from non-muscle to muscle invasive bladder cancer that commonly leads to metastasis. Cystoscopy and urine cytology are the standard procedures for its detection but have limited clinical sensitivity and specificity. Herein, a microfluidic device, the UriChip, was developed for the enrich...

One step forward towards the development of eco-friendly antifouling coatings: ...

Marine biofouling represents a global economic and ecological challenge and few eco-friendly antifouling agents are available. The aim of this work was to establish the proof of concept that a recently synthesized nature-inspired compound (gallic acid persulfate, GAP) can act as an eco-friendly and effective antifoulant when immobilized in coatings through a non-release strategy, promoting a long-lasting antifo...

Valores locais normais: deverão ser incluídos no controlo de qualidade dos Labo...

A interpretação dos valores funcionais obtidos por espirometria depende da comparação destes com valores ditos de referência ou previstos. Estes valores de referência derivam de equações construídas a partir de uma amostra de indivíduos considerados normais. Ora esta normalidade relaciona-se com as características próprias de cada população e, provavelmente, com a época em que esses valores de normalidade foram...

Pseudomyogenic hemangioendothelioma: a little-known tumor

Pseudomyogenic hemangioendothelioma (PHE) is a rare indolent vascular tumor that typically has a multifocal presentation and involves multiple tissue planes. This report describes a 34-year-old man with multiple infiltrated brown papules and plaques on his left leg that had evolved for 6 months. The skin biopsy revealed a dermal and subcutaneous neoplasm composed of fascicles of spindle cells with atypia and ep...

A granular cell tumor: an unusual colon polyp

We read with interest the article by Sevilla Ribota et al1 that described an unexpected finding of a granular cell tumour (GCT) of the rectum, which was removed by band ligation-assisted mucosectomy. We present a similar case of a GCT of the cecum, which was resected using a different endoscopic procedure.
