Ultrasound has increasingly become a clinical asset in the hands of the anesthesiologist and intensivist who cares for children. Though many applications for ultrasound parallel adult modalities, children as always are not simply small adults and benefit from the application of ultrasound to their management in various ways. Body composition and size are important factors that affect ultrasound performance in the child, as are the pathologies that may uniquely afflict children and aspects of procedures unique to this patient population...

BACKGROUND: Neoadjuvant therapy followed by surgery is the current recommended treatment for locally advanced esophageal carcinoma. Thoracic duct (TD) resection was indicated for radical mediastinal lymphadenectomy. However, TD resection can cause hemodynamic disturbances. The presence of metastasis in TD has not been previously studied. METHODS: Twenty-two patients who underwent minimally invasive esophagectomy with D2 lymphadenectomy after neoadjuvant chemoradiotherapy for esophageal squamous cell carcinoma were analyzed...

Novel endovascular techniques hope to offer patients aortic arch repair with reduced morbidity compared to conventional arch surgery; however, current endovascular strategies remain challenged by the proximal seal zone, higher stroke rates, long-term durability and select anatomy. Hybrid arch repair offers patients a less invasive alternative that can treat more distal aorta than conventional arch repair yet still be performed via standard sternotomy. Areas Covered: This review will discuss the current evidence and future development of hybrid aortic arch and frozen elephant trunk reconstruction...

Acute aortic injuries are not common in the setting of severe blunt trauma, but lead to significant morbidity and mortality. High-quality MDCT with 2D MPRs and 3D rendering are essential to identify aortic trauma and distinguish anatomic variants and other forms of aortic pathology from an acute injury. Misinterpretation of mimics of acute aortic injury can lead to unnecessary arteriography and thoracic surgery. Since most traumatic injuries occur in the distal arch, radiologists must be cognizant of the range of appearances of variants related to the ductus diverticulum...

Isolated intraspinal neurosarcoidosis is a rare clinical entity, with most reports describing intramedullary involvement in adults. We detail the case of a nine-year-old girl with rapid onset compressive myelopathy secondary to a thoracic epidural lesion. Although pathological diagnosis was challenging, a presumptive diagnosis of isolated extradural neurosarcoidosis was made in light of the patient's investigations and dramatic response to corticosteroids. Though less likely than neoplasia, rheumatologic processes such as inflammatory granulomatous disease warrant consideration in similar cases...

Thoracic aortic aneurysm (TAA) is progressive fatal aortic pathological dilation, which is characterized by increased proteoglycans and loss of elastic fibers. Recent advances on long non-coding RNAs (lncRNAs), an important regulator in many biological processes, suggested the close correlation between expression patterns and disease progression. In the present study, the ascending aortic tissues were collected from ascending TAA patients (n = 33) and organ donors (n = 16). Microarray analysis and real-time PCR were then applied to detect the lncRNA expression profiles...

The study purpose is to optimize modeling parameters, specifically segmentation spacing and centerline extraction, to efficiently construct accurate 3D aortic models. Models are constructed by centerline extraction and orthogonal 2D segmentations. We examine the effect of segmentation interval spacing (2, 1, 0.5, 0.25 cm) and orthogonal segmentation and centerline extraction iteration (one, two, three iterations) for constructing models of Healthy, Tortuous, Aneurysmal, and Dissected human thoracic aortas...

Circular RNAs (circRNAs) are a class of noncoding RNAs with continuous, covalently closed circular structures. Investigators have shown previously that circRNAs are regulators of gene expression in mammals. These tissue-specific transcripts are produced primarily by exonic or intronic sequences of housekeeping genes. Several biosynthetic models have been proposed for circRNAs, and consensus is lacking. CircRNAs are widely expressed in the cytoplasm and highly conserved, what is more, unlike other noncoding RNAs, circRNAs are relatively stable...

Background: Primary malignant chest-wall tumors (PMCWTs) are a heterogeneous group of tumors. They require a special experience in designing resection and reconstruction. They account for less than 1% of all primary malignant tumors. This study is designed to clarify different factors contributing to the outcome of patients with PMCWTs in our institution. Methods: A retrospective study included 98 patients with pathology proven PMCWTs, treated at the National Cancer Institute (NCI), Cairo University, Egypt, during the past 10 years...

Thoracic aortic aneurysm (TAA) is a highly lethal vascular disease. Long non-coding RNAs (lncRNAs) are newly discovered as a regulator of protein genes and play critical roles in cardiovascular physio-pathological processes. However, there were a few studies looking at lncRNAs in TAA. In this study, we profiled differential expression of lncRNAs between TAA (TAA group, N = 6) and normal thoracic aorta (control group, n = 6) by third-generation lncRNA microarray. We identified 1352 up-regulated and 1624 down-regulated lncRNAs with differential expression (log fold-change > 2...

Therapeutic proteins can facilitate the targeting and treatment of lymphatic diseases (such as cancer metastases, infections and inflammatory diseases) since they are cleared via the lymphatics following interstitial (SC or IM) administration. However, therapeutic proteins are often administered intravenously (IV). Recently therapeutic proteins have been found to access the thoracic lymph in surprisingly high quantities after IV administration. The aim of this study was to determine, for the first time, the major sites of thoracic lymph access of therapeutic proteins, and the protein properties that enhance lymph access, after IV administration...

BACKGROUND: Palliative thoracic radiotherapy (PTR) can relieve symptoms originating from intra-thoracic disease. The optimal timing and fractionation of PTR is unknown. Time to effect is 2 months. The primary aim of this retrospective study was to investigate survival after PTR, hypothesizing that a significant number of patients received futile fractionated PTR. The secondary aim was to find prognostic factors to guide treatment decisions. METHODS: Patients with non-small-cell lung cancer (NSCLC) planned for PTR in the period of 2010-2011 at the University Hospital of Copenhagen were included...
