The 21st century has seen several paradigm shifts in the treatment of non-small cell lung cancer (NSCLC) in early-stage inoperable disease, definitive locally advanced disease, and the postoperative setting. A key driver in improvement of local disease control has been the significant evolution of radiation therapy techniques in the last three decades, allowing for delivery of definitive radiation doses while limiting exposure of normal tissues. For patients with locally-advanced NSCLC, the advent of volumetric imaging techniques has allowed a shift from 2-dimensional approaches to 3-dimensional conformal radiation therapy (3DCRT)...

Background Transcatheter aortic valve implantation has been established as a safe and effective treatment option for patients at high or prohibitive surgical risk. However, some patients may not be suitable for the transfemoral approach due to severe iliofemoral disease or aneurysmal disease of the thoracoabdominal aorta. The aim of this case series was to evaluate the feasibility and clinical outcomes of the transaortic approach. Methods From May 2015 to June 2016, 5 patients (mean age 78.4 ± 3.9 years) with severe symptomatic aortic stenosis underwent transaortic transcatheter aortic valve implantation after a heart team discussion...

Tuberous sclerosis is an autosomal dominant disorder with a wide clinical spectrum of disease. It is characterized by development of benign tumors in multiple organs due to a disturbance in cellular growth and differentiation. It usually affects skin, brain, heart and kidney. Gastrointestinal involvement is rare and mainly restricted to adults and sigmoid colon and rectum. In children there are only two cases; our patient would be the third. We present a patient with tuberous sclerosis who began at the first month of life with repeated intestinal subocclusion...

Autogenous bone graft (autograft) remains the gold standard in the treatment of many orthopedic problems. However, graft harvest can lead to perioperative morbidity and increased cost. We tested the hypothesis that an osteoconductive matrix, beta-tricalcium phosphate (β-TCP), would be a safe and effective alternative to autograft alone. Beta-tricalcium phosphate (β-TCP) is considered as one of the most promising biomaterials for bone reconstruction. This study analyzes the outcomes of patients who received β-TCP as bone substitutes in orthopedic surgery...

BACKGROUND: Atrial fibrillation (AF) is the most frequent complication of surgery performed on cardiopulmonary bypass (CPB) and recent work associates CPB with postoperative inflammation. We have shown that all tissue injury releases mitochondrial damage associated molecular patterns (mtDAMPs) including mitochondrial DNA (mtDNA). This can act as a direct, early activator of neutrophils (PMN), eliciting a systemic inflammatory response syndrome (SIRS) while suppressing PMN function. Neutrophil Extracellular Traps (NETs) are crucial to host defence...

Considerable progress has been made in the management of patients with locally advanced or recurrent cancers of the pelvis over the past 60 years since the inception of pelvic exenteration. Early progress in pelvic exenteration was marred by the high surgical mortality and morbidity, which drew scepticism from the broader surgical community. Subsequent evolution in the procedure hinged on establishing surgical safety and a better understanding of outcome predictors. Surgical mortality from pelvic exenteration is now comparable to that of elective resection for primary colorectal cancers...

BACKGROUND: Operation of cortical veins is the keystone of parasagittal meningiomas (PSM) resection. Little is known about pathological changes of the veins and proper treatment. We built three-dimensional (3D) image fusion models by neuronavigation to analyze the features of peritumoral cortical veins for PSM and explore intraoperative treatment options. METHODS: We performed a prospective study of 42 consecutive surgically treated PSM patients who underwent preoperative evaluation of peritumoral cortical veins using a 3D venous-tumor fusion model established by a neuronavigation system...

Background: Aneurysmal bone cyst is a solitary bone tumor, expansile and lytic most often seen in the second decade of life, more frequently in men than in women (2: 1). They can occur in any bone, most common in the metaphysis of the long bones of the lower limbs. Although it is a benign tumor formation, aneurysmal cysts may have an aggressive local evolution and can cause a significant decrease in bone strength. The pacient may present local pain, the appearance of local deformation due to a tumor mass or occurrence of pathological fractures...
