Morpho-radiological and brain endocast analysis in the study of Hyperostosis Frontalis Interna (HFI): A combined approach.

The purpose of this study is to anatomically evaluate the impact on the patient intra vitam of an endocranial condition on a late 20th century skull housed in the Section of Legal Medicine of the University of Foggia (Foggia, Apulia, Italy). After performing a retrospective diagnosis, the condition is framed in the broader context of studies on this pathology. An anthropological and radiological analysis (X-ray and CT scan imaging) made it possible to confirm the preliminary information and to detail the osteological diagnosis of HFI.

The need for custom made frozen elephant trunk: when and where.

The frozen elephant trunk (FET) technique is an increasingly common procedure to treat complex extensive aortic disease both in elective and emergency setting. In a contemporary era, several prostheses are available to be used by surgeons performing such procedures, merging the advantages of endovascular and conventional surgery and preparing a more useful landing zone for second-stage downstream endovascular or open repair. Thoraflex hybrid (Terumo Aortic, Scotland) is a largely used hybrid vascular device merging a conventional surgical vascular graft made of gelatin-sealed woven polyester graft with a nitinol self-expanding stent graft.

Sudden Cardiac Death and Ex-Situ Post-Mortem Cardiac Magnetic Resonance Imaging: A Morphological Study Based on Diagnostic Correlation Methodology.

During the last years, post-mortem imaging has gradually been assumed within research in the field of forensic pathology. This role appears to be clearly and simply applied in the trauma field with the use of conventional radiography or Post Mortem Computed Tomography (PMCT). Recently, particular attention was paid to cardiovascular imaging using Post Mortem Magnetic Resonance Imaging (PMMRI).

Frozen Elephant Trunk Technique in Acute Type A Aortic Dissection: Is It for All?

Acute type A aortic dissection (ATAAD) is an indisputable emergency with very poor outcomes without surgical treatment. Although the aortic arch is often involved in the aortic dissection, its optimal management during surgical therapy remains uncertain. A conservative tear-oriented approach has traditionally been adopted, limiting the procedure to the ascending aorta (or hemiarch) replacement.

Caged-Ball Mitral Prosthesis Explanted After 50 Years.

We report a unique case of a Starr-Edwards prosthesis (model 6310, cloth covered) implanted in the mitral position by Christian Barnard that was successfully explanted and replaced after 50 years, the longest period free from valve dysfunction ever reported. Reoperation also included replacement of the native aortic valve combined with tricuspid valve annuloplasty. ().

DXA parameters, Trabecular Bone Score (TBS) and Bone Mineral Density (BMD), in fracture risk prediction in endocrine-mediated secondary osteoporosis.

Osteoporosis, a disease characterized by low bone mass and alterations of bone microarchitecture, leading to an increased risk for fragility fractures and, eventually, to fracture; is associated with an excess of mortality, a decrease in quality of life, and co-morbidities. Bone mineral density (BMD), measured by dual X-ray absorptiometry (DXA), has been the gold standard for the diagnosis of osteoporosis. Trabecular bone score (TBS), a textural analysis of the lumbar spine DXA images, is an index of bone microarchitecture.

A modified frozen elephant trunk hybrid device to facilitate supra-aortic trunk anastomosis.

Reimplantation of the supra-aortic vessels can be challenging with Thoraflex Hybrid. A device modification made the vessel lengths more appropriate and the position of the neo-vessels in the chest avoided malpositioning and kinking and facilitated sternum closure; this may improve operating times as well as allowing complete and continuous cerebral trivascular perfusion and corrects positioning of the intrathoracic vessels.

Radiographic/MR Imaging Correlation of Spinal Bony Outlines.

The human spine is a highly specialized structure that protects the neuraxis and supports the body during movement, but its complex structure is a challenge for imaging. Radiographs can provide fine bony detail, but lack soft tissue definition and can be complicated by overlying structures. MR imaging allow(s) excellent soft tissue contrast, but some bony abnormalities can be difficult to discern.

A new corrective model to evaluate TBS in obese post-menopausal women: a cross-sectional study.

Introduction: The relationship between post-menopausal osteoporosis and obesity has been mainly investigated using bone mineral density (BMD) as marker of bone health. Since BMD does not reflect bone microarchitecture, another analytical tool, the Trabecular Bone Score (TBS), has been recently developed for this purpose. In this study, we intended to investigate the validity of TBS as marker of bone quality in obese post-menopausal women.

Postmortem Imaging: An Update.

Postmortem imaging is a fascinating field of forensic radiology that has seen extraordinary growth in the last 10 years. Indeed, if autopsy represents the sole reliable method of determining the definitive cause of death, imaging may provide an efficient guide to supplement conventional autopsy. This is particularly true because of several techniques that are currently available, such as postmortem computed tomography, multiphase postmortem computed tomography angiography, and postmortem magnetic resonance imaging.

Quantitative analysis of modified functional muscle-bone unit and back muscle density in patients with lumbar vertebral fracture in Chinese elderly men: a case-control study.

Objectives: Bone mineral density (BMD) is associated with muscle mass and quality, but little research has been done on functional muscle-bone unit and back muscle density in patients with lumbar vertebral fracture. This study used the "modified functional muscle-bone unit" concept and measured back muscle density to investigate muscle-bone interaction difference between the fracture and control group.

Methods: This was a case-control study.

Neurofibromatosis 1 and massive hemothorax: a fatal combination.

Type 1 neurofibromatosis (NF 1), a rare genetic disease with autosomal dominant transmission, has typical dermatologic manifestations with pathognomonic Lisch nodules, and is rarely known for vascular alterations. Among these, aneurysmal dilatation is the most common form. We report a fatal case of massive hemothorax due to a spontaneous rupture of the left pulmonary artery branch micro-aneurysm in a NF 1 patient.

Additional value of inflammatory biomarkers and carotid artery disease in prediction of significant coronary artery disease as assessed by coronary computed tomography angiography.

Aims: To evaluate the relationship between an incremental model including cardiovascular risk factors, carotid disease, and inflammatory biomarkers to predict the presence of obstructive coronary artery disease (CAD).

Methods And Results: A total of 134 consecutive and asymptomatic intermediate-risk patients (mean age 61 ± 9 years, 52% men) were enrolled. Each subject underwent circulating levels assessment of interleukin (IL)-2r, IL-6, IL-8, IL-10, high-sensitivity C-reactive protein (hs-CRP) and carotid and coronary artery evaluation using carotid ultrasound and coronary computed tomography angiography (CCTA), respectively.

Body composition in clinical practice.

Nutritional status is the results of nutrients intake, absorption and utilization, able to influence physiological and pathological conditions. Nutritional status can be measured for individuals with different techniques, such as CT Body Composition, quantitative Magnetic Resonance Imaging, Ultrasound, Dual-Energy X-Ray Absorptiometry and Bioimpendance. Because obesity is becoming a worldwide epidemic, there is an increasing interest in the study of body composition to monitor conditions and delay in development of obesity-related diseases.

Wernicke's encephalopathy after allogeneic stem cell transplantation.

Wernicke's encephalopathy is an acute neuropsychiatric condition due to thiamine deficiency frequently associated with chronic alcohol abuse. We describe 2 cases of patients who experienced acute Wernicke's encephalopathy after allogeneic stem cell transplantation associated with the use of commercial total parental nutrition. Early diagnosis with magnetic resonance imaging and timely treatment with thiamine resulted in rapid resolution of clinical and radiological signs.
