PURPOSE: To evaluate contemporary practice patterns in the management of small renal masses. METHODS: We identified 52,804 patients within the National Cancer Database diagnosed with a small renal mass (≤4cm) between 2010-2014. Utilization trends for active surveillance, ablation, and robotic, laparoscopic, and open surgical techniques were compared among all-comers, elderly patients (≥75 years) and individuals with competing health risks (Charlson index ≥2)...

Iatrogenic ureteral injuries are a source of major concern among surgeons performing colorectal procedures. Although they are uncommon, these lesions lead to severe morbidity and long-term functional disabilities, as well as an increase in mortality, hospital stay, and cost. The laparoscopic approach has gained popularity in the field of colorectal surgery and is associated with improved global postoperative outcomes. However, it is also considered to increase the risk of ureteral injury when compared to open surgery, especially during left colonic and rectal resections...

The tremendous advances in endoscopic skull base surgery added new a set of intricate less invasive approaches to the neurosurgical armamentarium. The new generations of neurosurgeons face the challenge of adopting the ever-changing technology and quickly learning modern surgical techniques beyond the traditional neurosurgery comfort zone. The future skull base surgeon must be well trained and knowledgeable in all surgical portals to the skull base in order to select the safest least invasive, most direct approach that offers the optimum exposure to handle a complex skull base pathology...

Early stage detection of cancer is essential for the improved long-term survival of patients. Currently, costly, extensively complex and invasive procedures, such as surgical tissue biopsies, are used for cancer screening. Thus, over the past few decades, advancements in microfluidics and lab-on-a-chip approaches have been made to develop minimally invasive and miniaturized platforms to identify and segregate circulating cancer biomarkers such as exosomes, circulating tumor cells (CTCs) and cell-free DNA (cfDNA) from body fluids...

Orthopaedic disorders are very frequent, globally found and often partially unresolved despite the substantial advances in science and medicine. Their surgical intervention is multifarious and the most favourable treatment is chosen by the orthopaedic surgeon on a case-by-case basis depending on a number of factors related with the patient and the lesion. Numerous regenerative tissue engineering strategies have been developed and studied extensively in laboratory through in vitro experiments and preclinical in vivo trials with various established animal models, while a small proportion of them reached the operating room...

Vertebral compression fractures (VCFs) may result in a kyphotic deformity which can cause potential systemic complications secondary to respiratory and gastrointestinal dysfunction. The use of implants in the spine for VCF treatment represents a paradigm shift away from cement injection on its own, aiming to combine the analgesic and stabilizing effect of injecting cement into the vertebral body with vertebral height restoration and kyphotic angle correction. Spine implants which can be used for VCF treatment include stents, jacks, PEEK cages and fracture reduction systems...

BACKGROUND: Resuscitative endovascular balloon occlusion of the aorta (REBOA) for control of non-compressible torso hemorrhage is a technology that is increasingly being utilized in the combat casualty setting. Its use in the resource restricted environment holds potential to improve hemorrhage control, decrease blood product utilization, decrease morbidity, and improve combat mortality. The objective of this report is to present the single largest series of REBOA use on severely injured combat casualties...

Perioperative peripheral nerve injury (PNI) is a well-recognized complication of general anesthesia that continues to result in patient disability and malpractice claims. However, the multifactorial etiology of PNI is often not appreciated in malpractice claims given that most PNI is alleged to be due to errors in patient positioning. New advances in monitoring may aid anesthesiologists in the early detection of PNI. This article reviews recent studies of perioperative PNI after general anesthesia and discusses the epidemiology and potential mechanisms of injury and preventive measures...

Ambient Mass Spectrometry (MS) analysis is widely used to characterize biological and non-biological samples. Advancements that allow rapid analysis of samples by ambient methods such as Desorption Electrospray Ionization Mass Spectrometry (DESI-MS) and Rapid Evaporative Ionization Mass Spectrometry (REIMS) are discussed. A short, non-comprehensive overview of ambient MS is provided that only contains example applications due to space limitations. A spatially encoded mass spectrometry analysis concept to plan cancer resection is introduced...

BACKGROUND: The best treatment for fractures of the distal tibia remains controversial. Most of these fractures require surgical fixation, but the outcomes are unpredictable and complications are common. OBJECTIVES: To assess disability, quality of life, complications and resource use in patients treated with intramedullary (IM) nail fixation versus locking plate fixation in the 12 months following a fracture of the distal tibia. DESIGN: This was a multicentre randomised trial...

Occlusive artery disease (CAD) is the leading cause of death worldwide. Bypass graft surgery remains the most prevalently performed treatment for occlusive arterial disease, and veins are the most frequently used conduits for surgical revascularization. However, the clinical efficacy of bypass graft surgery is highly affected by the long-term potency rates of vein grafts, and no optimal treatments are available for the prevention of vein graft restenosis (VGR) at present. Hence, there is an urgent need to improve our understanding of the molecular mechanisms involved in mediating VGR...

OBJECTIVE: The anatomy of the head and neck region is complex as are its implications for maxillofacial pathologic conditions and their surgical treatments. We hypothesize that the assessment of the surgical management of orbital floor fractures by using titanium mesh could represent an appropriate first experimental field for the use of the Anatomage Table in maxillofacial surgery. STUDY DESIGN: Patients with unilateral orbital floor fractures were searched for in the hospital database of Novara University Hospital, Novara, Italy...

PURPOSE: Carpal tunnel release (CTR) is a common surgical procedure, representing a financial burden to the health care system. The purpose of this study was to test whether the choice of CTR technique (open carpal tunnel release [OCTR] vs endoscopic carpal tunnel release [ECTR]), surgical setting (operating room vs procedure room [PR]), and anesthetic type (local, monitored anesthesia care [MAC], Bier block, general) affected costs or payments. METHODS: Consecutive adult patients undergoing isolated unilateral CTR between July 2014, and October 2017, at a single academic medical center were identified...

Genetically engineered mouse models (GEMMs) are extremely valuable in revealing novel biological insights into the initiation and progression mechanisms of human diseases such as cancer. Transgenic and conditional knockout mice have been frequently used for gene overexpression or ablation in specific tissues or cell types in vivo. However, generating germline mouse models can be time-consuming and costly. Recent advancements in gene editing technologies and the feasibility of delivering DNA plasmids by viral infection have enabled rapid generation of non-germline autochthonous mouse cancer models for several organs...

Congenital heart defects (CHDs) are the most common cause of childhood morbidity and early mortality. Prenatal detection of the underlying molecular mechanisms of CHDs is crucial for inventing new preventive and therapeutic strategies. Mutant mouse models are powerful tools to discover new mechanisms and environmental stress modifiers that drive cardiac development and their potential alteration in CHDs. However, efforts to establish the causality of these putative contributors have been limited to histological and molecular studies in non-survival animal experiments, in which monitoring the key physiological and hemodynamic parameters is often absent...
