Novel minimally invasive abdominoplasty for selected cases of prune belly syndrome: Step-by-step technique description and clinical indications.

Background: Prune belly syndrome (PBS) is characterized by the triad of abdominal flaccidity, bilateral undescended testicles and genitourinary tract anomalies. A variable spectrum of abdominal wall laxity is observed in PBS. We present the first case of a novel technique using a minimally invasive abdominoplasty to specifically address patients with localized abdominal wall weakness in PBS.

Evaluation of uro-oncological surgical treatment during the Sars-CoV-2 pandemic in a Brazilian tertiary oncology institution, the new world epicenter.

Introduction: The rapid spread of coronavirus disease 2019 (COVID-19) has dramatic effects on individuals and health care systems. In our institute, a tertiary oncologic public hospital with high surgical volume, we prioritize maintaining cancer treatment as well as possible. The aim of this study is to evaluate if uro-oncological surgeries at pandemic are safe.

Previously unseen 80L giant hydronephrosis.

Here we describe the case of a patient who was referred to our institution with an immense abdominal volume of unknown origin. The patient was unable to stand up and therefore was bedridden. A giant hydronephrotic kidney was diagnosed and total volume of urine removed was 80L.

Magnetoresistive immunosensor for the detection of Escherichia coli O157:H7 including a microfluidic network.

A hand held device has been designed for the immunomagnetic detection and quantification of the pathogen Escherichia coli O157:H7 in food and clinical samples. In this work, a technology to manufacture a Lab on a Chip that integrates a 3D microfluidic network with a microfabricated biosensor has been developed. With this aim, the sensing film optimization, the design of the microfluidic circuitry, the development of the biological protocols involved in the measurements and, finally, the packaging needed to carry out the assays in a safe and straightforward way have been completed.
