The analysis of lung sounds, collected through auscultation, is a fundamental component of pulmonary disease diagnostics for primary care and general patient monitoring for telemedicine. Despite advances in computation and algorithms, the goal of automated lung sound identification and classification has remained elusive. Over the past 40 years, published work in this field has demonstrated only limited success in identifying lung sounds, with most published studies using only a small numbers of patients (typically N<;20) and usually limited to a single type of lung sound...

Sleep disturbance contributes to impaired procedural learning in schizophrenia, yet little is known about this relationship prior to psychosis onset. Adolescents at ultra high-risk (UHR; N=62) for psychosis completed the Pittsburgh Sleep Quality Index (PSQI) and a procedural learning task (Pursuit Rotor). Increased self-reported problems with sleep latency, efficiency, and quality were associated with impaired procedural learning rate. Further, within-sample comparisons revealed that UHR youth reporting better sleep displayed a steeper learning curve than those with poorer sleep...

BACKGROUND: The deficit of donor sites in major burns over 50% of the total body surface area has necessitated the application of methods besides traditional meshed autografting to achieve definitive skin cover. The Meek micrografting technique was introduced at this hospital in 2011, especially in the absence of a reliable source of deceased donor allograft skin. The purpose of this study was to evaluate this strategy with reference to its technical execution, efficacy and indications in the context of major paediatric burn surgery...

PURPOSE: Surgeons tend to view the robotic right colectomy (RRC) as an ideal beginning procedure to gain proficiency in robotic general and colorectal surgery. Nevertheless, oncological RRC, especially if performed with intracorporeal ileocolic anastomosis confectioning, cannot be considered a technically easier procedure. The aim of this study was to assess the learning curve of the RRC performed for oncological purposes and to evaluate its safety and efficacy investigating the perioperative and pathology outcomes in the different learning phases...

In total hip arthroplasty (THA), the accurate positioning of implants is the key to achieve a good clinical outcome. Computer-assisted orthopaedic surgery (CAOS) has been developed for more accurate positioning of implants during the THA. There are passive, semi-active, and active systems in CAOS for THA. Navigation is a passive system that only provides information and guidance to the surgeon. There are 3 types of navigation: imageless navigation, computed tomography (CT)-based navigation, and fluoroscopy-based navigation...

Corneal transplant is the main treatment for blindness caused by corneal diseases. The common methods of corneal transplant include penetrating keratoplasty and lamellar keratoplasty. With the advances of microsurgical instruments and technology in recent years, deep anterior lamellar keratoplasty (DALK) has gradually increased. Compared with conventional penetrating keratoplasty, the optical effects of DALK are not much different, but DALK has fewer complications. So DALK is expected to become the mainstream of corneal transplantation...

Lichtenstein hernioplasty is the number one technique worldwide for open, mesh-based inguinal hernia repair. The principle of Lichtenstein hernioplasty is the tension-free reinforcement of the abdominal wall by covering the transversalis fascia and the oblique muscles with an artificial patch of mesh. The Lichtenstein technique has been modified since its inception. The technique has the benefits of low costs and a rapid learning curve and can be performed with the patient under local anesthesia. The recurrence rates after the Lichtenstein operation are significantly lower compared to open suture repair and equal to laparoendoscopic techniques...

OBJECTIVE Treatment of wide-necked intracranial aneurysms is associated with higher recanalization and complication rates; however, the most commonly used methods are not specifically designed to work in bifurcation lesions. To address these issues, the authors describe the evolution in the design and use of the eCLIPs (Endovascular Clip System) device, a novel hybrid stent-like assist device with flow diverter properties that was first described in 2008. METHODS A registry was established covering 13 international centers at which patients were treated with the second-generation eCLIPs device...

PURPOSE OF REVIEW: The leading cause of voiding dysfunction in older men is benign prostatic obstruction. In the setting of a grossly enlarged prostate (>80cm(3)), an open simple prostatectomy has been the gold standard for surgical treatment. Here, we will discuss the minimally invasive robot-assisted approach and compare it to the classic open approach and holmium laser enucleation of the prostate. RECENT FINDINGS: Literature on robot-assisted simple prostatectomy, in concurrence with our institutional experience, has shown an overall lower morbidity, shorter hospital stay, and decreased indwelling catheter time, with equivalent functional outcomes compared to open simple prostatectomy...

INTRODUCTION: Three-dimensional (3D) planning in oral and maxillofacial surgery has become a standard in the planification of a variety of conditions such as dental implants and orthognathic surgery. By using custom-made cutting and positioning guides, the virtual surgery is exported to the operating room, increasing precision and improving results. MATERIALS AND METHODS: We present our experience in the treatment of craniofacial deformities with 3D planning. Software to plan the different procedures has been selected for each case, depending on the procedure (Nobel Clinician, Kodak 3DS, Simplant O&O, Dolphin 3D, Timeus, Mimics and 3-Matic)...

Hippocampal-dependent deficits in learning and memory formation are a prominent feature of traumatic brain injury (TBI), however the role of the hippocampus in cognitive dysfunction after concussion (mild TBI) is unknown. We therefore investigated functional and structural changes in the swine hippocampus following TBI using a model of head rotational acceleration that closely replicates the biomechanics and neuropathology of closed-head TBI in humans. We examined neurophysiological changes using a novel ex vivo hippocampal slice paradigm with extracellular stimulation and recording in the dentate gyrus and CA1 occurring at 7 days following non-impact inertial TBI in swine...

Autogenous fistulas and in particular radiocephalic fistulas are recommended as the first vascular access for hemodialysis. Unfortunately, the rates of early failure and non-maturation are very high. For more than a decade, brachial plexus block has been proposed as the anesthesia of choice for fistula creation due to its beneficial sympathectomy-like effect, causing vasodilation and attenuation of spasm. Until recently, there was not a single randomized clinical study supporting this proposition. Because performing regional anesthesia is time-consuming and requires expertise, many surgeons prefer local or general anesthesia for vascular access surgery...
