A Force Estimation Sensor System TestBed for Geological Phenomena Analysis based on Biomimetic

Our work focuses, on designing and proposing a force estimation sensor system for Geological phenomena data collection and analysis, based on Biomimetic. In this sense, biomimetic term, is used, as proposed by Schmitt in its classical sense, with regatd to the study of nature's methods, processes and mechanisms. In particular, strain gauge sensors with force sensing resistor (FSR), formate a clustering to estimate ground stress and tension levels, as stated by natures' mechanisms in earthworms to detect electrical signals. Our sensor system is proposed as a testbed to estimate geological landslide phenomena. Our experimental results from the data collection system is conducted in LabVIEW. © 2022 IEEE

The Mini Lap Percutaneous Surgical System with MiniGrip® Handle is currently the less invasive instrument and can be applied to a wide range of operations. The current paper presents its application on percutaneous laparoscopic cholecystectomy. Materials and methods: From January 2017 to June 2017, 32 patients underwent percutaneous laparoscopic cholecystectomy with the MiniLap® system. All operations were performed by the same surgical team. Results: No conversions and no overall complications were reported. Drainage were not necessary. Mean surgical time was 35 minutes, while patients were released in <24 hours after the operation. Conclusion: The MiniLap system with the use of the mini grip handle seems to sustain the benefits of performing laparoscopically. However, further trials should be conducted so as to establish its safety on cholecystectomies.

Giant Echinococcosis of the Liver with Suppuration: A Case Report and Review of the Literature

Purpose: Cystic echinococcosis (CE) is a common, complex parasitic disease that constitutes a major public health concern. CE demonstrates high endemicity in areas where dogs are used for herding or where animal husbandry practices involve close contact with livestock. It can clinically manifest with a variety of signs and symptoms, such as cholangitis, jaundice, pancreatitis, external biliary fistula, inferior vena cava obstruction, portal hypertension, and superinfection. The latter can notably be related to suppuration, either by rupture or bacteremia. The aim of this study is to report our 76-year-old patient who presented with a primarily infected giant-suppurated hydatid cyst of the liver and its surgical management. Methods: In this case, the diagnosis was based primarily on clinical presentation, computed tomography (CT) scan, and magnetic resonance imaging (MRI) of the patient’s abdomen. The surgical procedure of choice was the partial retaining of the pericystic membrane and drainage of the cystic contents (partial pericystectomy). Results: The surgical management and meticulous long-term follow-up of our patient produced a positive outcome without any post-operative complications
