A piezoelectric instrument vibrating in the ultrasonic frequency range was investigated for its potential use in periodontal resective therapy. The rate of postoperative wound healing (baseline and 14, 28, and 56 days after surgery) in a dog model following surgical ostectomy and osteoplasty was the marker used to compare the efficacy of this instrument (PS) with a commonly used carbide bur (CB...

conclusions timely detection and appropriate antibiotic therapy of afbn are essential to prevent renal abscess formation. a possible diagnosis of afbn needs to be considered in all patients being treated for febrile uti. detection and surgical correction of the underlying malformation are necessary to prevent further recurrences. case presentation here we describe a case of a 4-year-old boy adm...

One of the important features of digital instrumentation and control (I&C) systems is the faulttolerant technique. Fault-tolerance is the system’s capability to help the system perform correctly the specific required functions in spite of the presence of faults. In the fault tolerance evaluation, fault detection coverage is a crucial factor. The fault detection coverage is the ability to detect...

An integrated portable genetic analysis microsystem including PCR amplification and capillary electrophoretic (CE) analysis coupled with a compact instrument for electrical control and laser-excited fluorescence detection has been developed. The microdevice contains microfabricated heaters, temperature sensors, and membrane valves to provide controlled sample positioning and immobilization in 2...

Instrument activity detection is a fundamental task in music information retrieval, serving as basis for many applications, such recommendation, tagging, or remixing. Most published works on this cover popular and smaller ensembles. In paper, we embrace orchestral opera recordings rarely considered scenario automated instrument detection. Orchestral particularly challenging since it consists of...

PURPOSE To assess the impact of refractive surgery on quality of life using the National Eye Institute Refractive Error Quality of Life instrument (NEI-RQL) and to evaluate the responsiveness of our Portuguese version of the NEI-RQL instrument to surgical correction of refractive error. METHODS In this prospective study, the NEI-RQL, a 42-item questionnaire with 13 scales, was self-administer...

The closure of the abdominal wall after making a laparotomy is a major challenge for surgeons, since a significant percentage of closures fail and incisional hernias rise. The suture has to withstand the forces required to close the incision, while not hindering the adequate wound healing progression. Currently, there is no surgical measuring device that could be used to determine the required ...

A hybrid physical-based deformation modeling (HPDM) technique for our laparoscopic surgery simulation system is proposed. The proposed technique consists of three components: (i) approximate continuum free-form deformation modeling, (ii) efficient collision detection for non-rigid objects, and (iii) mass-spring modeling for force feedback implementation. Three physical-based deformation modelin...

Minimally-invasive interventions offers multiple benefits for patients, but also entails drawbacks for the surgeon. The goal of context-aware assistance systems is to alleviate some of these difficulties. Localizing and identifying anatomical structures, maligned tissue and surgical instruments through endoscopic image analysis is paramount for an assistance system, making online measurements a...
