Epilepsy is a common neurological disorder which affects 0.5–1% of the world population. Its diagnosis relies both on Electroencephalogram (EEG) findings and characteristic seizure−induced body movements − called seizure semiology. Thus, synchronous EEG (2D)video recording systems (known as Video−EEG) are most accurate tools for epilepsy diagnosis. Despite establishment several quantitative methods analysis, semiology still analyzed by visual inspection, based epileptologists’ subjective...
Human motion analysis can provide valuable information for supporting the clinical assessment of movement disorders, such as Parkinson's disease (PD). In this contribution, we study suitability a Kinect v2 based system PD in environment, comparison to original (v1). study, 3-D body joint data were acquired from both normal subjects, and patients treated with deep brain stimulation (DBS). Then, several gait parameters extracted gathered data. The obtained results show that 96% considered are...
Movement-related diseases, such as Parkinson's disease (PD), progressively affect the motor function, many times leading to severe impairment and dramatic loss of patients' quality life. Human motion analysis techniques can be very useful support clinical assessment this type diseases. In contribution, we present a RGB-D camera (Microsoft Kinect) system its evaluation for PD assessment. Based on skeleton data extracted from gait three patients treated with deep brain stimulation control...
Human gait analysis provides valuable information regarding the way of walking a given subject. Low-cost RGB-D cameras, such as Microsoft Kinect, are able to estimate 3-D position several body joints without requiring use markers. This can be used perform objective in an affordable, portable, and non-intrusive way. In this contribution, we present system for fully automatic using single camera, namely second version Kinect. Our does not require any manual intervention (except...
Motion analysis systems based on a single markerless RGB-D camera are more suitable for clinical practice than multi-camera marker-based reference systems. Nevertheless, the validity of cameras motor function assessment in some diseases affecting gait, such as Transthyretin Familial Amyloid Polyneuropathy (TTR-FAP), is yet to be investigated. In this study, agreement between Kinect v2 and system obtaining spatiotemporal kinematic gait parameters was evaluated context TTR-FAP. 3-D body joint...
Many neurological diseases, such as Parkinson's disease and epilepsy, can significantly impair the motor function of patients, often leading to a dramatic loss their quality life. Human motion analysis is regarded fundamental towards an early diagnosis enhanced follow-up in this type diseases. In contribution, we present NeuroKinect, novel system designed for This includes RGB-D camera (Microsoft Kinect) two integrated software applications, KiT (KinecTracker) KiMA (Kinect Motion Analyzer)....
Complete traumatic upper extremity avulsions are an infrequent but devastating injury. These injuries usually the result of massive blunt trauma to limb. Intact issue from amputated or nonsalvageable limbs may be transferred for reconstruction complex defects resulting when indications replantation not met. This strategy allows preservation stump length coverage exposed joints, and provides free flap harvest without additional donor-site morbidity.A retrospective review at São João Hospital...
Transthyretin Familial Amyloid Polyneuropathy (TTR-FAP) is a rare and disabling neurological disorder caused by mutation of the transthyretin gene. One disease's characteristics that mostly affects patients' quality life its influence on locomotion, with variable evolution timing. Quantitative motion analysis useful for assessing motor function, including gait, in diseases affecting movement. However, it still an evolving field, especially TTR-FAP, only few available studies. A single...
The chest wall chondrosarcoma (CWC) is a rare slowly growing primary tumor of the with an incidence <0.5 per million person-years.We present case giant CWC that caused mass effect on mediastinum, heart, and lung.Large tumors thoracic structures compression may be life threatening, its resection subsequent reconstruction represent significant multidisciplinary surgical challenge.In this case, despite large dimensions, preoperative planning-sparing key reconstructive options without...
Background Implant-based breast reconstruction has evolved tremendously in the last decades, mainly due to development of new products and techniques that make procedure safer more reliable. The purpose this study was compare outcomes immediate one-stage between acellular dermal matrix (ADM) inferior flap (IDF). Methods We conducted a retrospective comparative patients submitted reconstructions with an anatomical implant ADM or IDF single center 2016 2018. Outcomes evaluated included major...

Transthyretin Familial Amyloid Polyneuropathy (TTR-FAP) is a rare neurological disease caused by genetic mutation with variable presentation and consequent challenging diagnosis, complex follow-up treatment. At this moment, condition has no cure treatment options are under development. One of the disease's implications definite progressive motor impairment that from early stages compromises walking ability daily life activities. The detection key for onset diagnosis. With goal improving...
Hereditary Amyloidosis associated with variant Transthyretin (ATTRv Amyloidosis) is a progressive and highly disabling neurological disorder that affects gait. Quantitative motion analysis useful for assessing motor function, including gait, in diseases affecting movement. A single markerless RGB-D camera enables 3D full-body capture less expensive intrusive, more portable way than multi-camera marker-based systems. In this study, we examine whether gait system based on an can be used to...
Abstract Background This study aimed to analyze the effect of body mass index (BMI), age, and tobacco use on alloplastic breast reconstruction. Methods We conducted a retrospective patients who submitted immediate reconstructions with an anatomical implant acellular dermal matrix in single center between 2016 2018. Outcomes evaluated included complications, early reinterventions, readmissions, reconstruction failure. Patients were divided into two groups concerning each potential risk factor...
A 38-year-old man developed an infection that led to necrosis of the abdominal wall after perforation a gastric ulcer. split-thickness skin graft over viscera was used achieve temporary primary closure. After full systemic and local stabilisation, it reconstructed with free innervated latissimus dorsi myocutaneous flap.
