Cardiovascular Magnetic Resonance Imaging (CMR) permits accurate phenotyping of many cardiac diseases. CMR's inherent advantages are its non-invasive nature, lack of ionizing radiation and high accuracy and reproducibility. Furthermore, it is able to assess many aspects of cardiac anatomy, structure and function. Specifically, it can characterize myocardial tissue, myocardial function, myocardial mass, myocardial blood flow/perfusion, irreversible and reversible injury, all with a high degree of accuracy and reproducibility...

Current total knee replacement designs work to address clinically desired knee stability and range of motion through a balance of retained anatomy and added implant geometry. However, simplified implant geometries such as bearing surfaces, posts, and cams are often used to replace complex ligamentous constraints that are sacrificed during most total knee replacement procedures. This article evaluates a novel total knee replacement design that incorporates synthetic ligaments to enhance the stability of the total knee replacement system...

Posterosuperior repair of the rotator cuff is one of the most frequently performed surgical procedures in the shoulder. Its aim is to fix the tendon back to the bone to restore anatomy, improve shoulder function, and prevent progression of cuff tear arthropathy and attendant muscle degeneration. Despite technical advances in this procedure, in some cases, the tendon cannot be fixed back to the footprint without excessive tension on the repair. In young patients or in patients with low-grade muscle atrophy and fatty degeneration (Goutallier grade 1 or 2), it is mandatory to attempt fixation of the tendon to restore functional anatomy and prevent further muscle degeneration...

BACKGROUND AND IMPORTANCE: Resection of cerebellopontine angle tumors is challenging because the proximity of the facial nerve puts it at risk of inadvertent injury and subsequent dysfunction. It is critical to consider variations in anatomy and be aware of the potential deviations in the course of the nerve in order to avoid damage. CLINICAL PRESENTATION: We present a case of a facial nerve bifurcation identified during resection of a vestibular schwannoma. CONCLUSION: This is the only reported case of proximal facial nerve bifurcation...

AIMS: The effect of extravascular lung water (EVLW) and relationship to functional status as a result of acute decompensated heart failure (ADHF) are not well understood. We sought to quantify changes in clinical variables, EVLW, airway anatomy, spirometry, and diffusing capacity for carbon monoxide before and after treatment for ADHF. METHODS AND RESULTS: Fifteen patients were recruited within 24 h of hospital admission. Spirometry, diffusing capacity for carbon monoxide, and surrogates of EVLW by computed tomography were measured and were then repeated within 24 h of discharge...

Myocardial infarction and subsequent heart failure is a major health burden associated with significant mortality and morbidity in western societies. The ability of cardiac tissue to recover after myocardial infarction is affected by numerous complex cellular and molecular pathways. Unbalance or failure of these pathways can lead to adverse remodelling of the heart and poor prognosis. Current clinical cardiac imaging modalities assess anatomy, perfusion, function, and viability of the myocardium, yet do not offer any insight into the specific molecular pathways involved in the repair process...

Introduction: Scaphoid fractures are not very common and frequently remain undiagnosed, presenting in non-union and persistent wrist pain. Options for scaphoid fracture treatment have been described over several decades, however, none with an optimal solution to achieve union along with good hand function. We describe here, the use of vascularised corticoperiosteal bone grafts from the medial femoral condyle (MFC) as a solution for the difficult problem of scaphoid fracture non-union...

Methimazole (MMI) and propylthiouracil (PTU) are widely used antithyroid drugs (ATD) that have been approved for the treatment of hyperthyroidism. Hepatotoxicity may be induced by these drugs, though they exert dissimilar incidence rates of hepatotoxicity and, possibly, with different underlying pathogenic mechanisms. We report the case of a 55-year-old woman with no relevant medical history diagnosed with hyperthyroidism due to Graves' disease, who developed two episodes of acute hepatitis concurrent with the consecutive administration of two different ATDs, first MMI and then PTU...

Elasticity is a fundamental cellular property that is related to the anatomy, functionality, and pathological state of cells and tissues. However, current techniques based on cell deformation, atomic force microscopy, or Brillouin scattering are rather slow and do not always accurately represent cell elasticity. Here, we have developed an alternative technique by applying shear wave elastography to the micrometer scale. Elastic waves were mechanically induced in live mammalian oocytes using a vibrating micropipette...

The main advantage of endoscopic laser surgery for laryngeal cancer is to allow tumour resection, while limiting functional sequelae, thereby improving the postoperative course. In this type of surgery, the epiglottis is often partially resected, leaving a raw zone without any reconstruction. The surgical technique described here involves endoscopic reconstruction of the epiglottis after partial resection. The sectioned edge of the epiglottis is sutured to the base of the tongue to create a neoepiglottis and to reconstruct the vallecula, thus resembling preoperative anatomy, allowing improvement of postoperative swallowing...

INTRODUCTION: The repair of the scleral flap is often needed in cases of severe hypotony or bleb leaks with over filtration. We present a simple novel technique to restore the hinged flap using a scleral patch graft. MATERIALS AND METHODS: We present 4 eyes of 4 patients that present with hypotony (IOP <6▒mm Hg) from overfiltration secondary to loose scleral flap (2 eyes) and bleb leak (2 eyes). A scleral patch from human donor preserved in 95% ehtanol is cut in a trapezoidal shape and placed over the area of filtration after a conjunctival peritomy...

Paul S Larson, Philip A Starr, Alastair J Martin
Interventional and intraoperative MRI approaches to deep brain stimulator implantation are relatively new, and in their purest form represent a distinct departure from traditional stereotactic techniques. They employ a novel means of stereotaxis based on regions of interest in the MR space and simple geometric principles, which eliminate the need for a stereotactic frame. This approach is appropriate for targets that are MR visible, and for whom the local anatomy and function are well characterized. It may also be appropriate for targets that do not have a well-described physiologic signature and for which clinical response to macrostimulation does not play a critical role...

The neural connections of the basal ganglia provide important insights into their function. Here, we discuss the current perspective on basal ganglia connections with the cerebral cortex and with the cerebellum. We review the evidence that the basal ganglia participate in functionally segregated circuits with motor and non-motor areas of the cerebral cortex. We then discuss the data that the basal ganglia are interconnected with the cerebellum. These results provide the anatomical substrate for basal ganglia contributions not only to the control of movement, but also to a variety of cognitive and affective functions...

The uncinate fasciculus is the largest white matter association tract connecting the prefrontal cortex and the anteromedial temporal lobe. The traditional anatomical description outlines a temporal stem that hooks around the posterior insula, a subinsular body, and 2 prefrontal stems extending to the lateral orbital gyri and the frontopolar cortex. Recent imaging studies of the white matter tracts deep to the subgenual cingulate gyrus (Brodmann area 25: BA25) suggest the presence of white matter fibers extending from BA25 to the amygdala, via a route that would run in close proximity to the uncinate fasciculus, that are of functional importance in mood disorders...

Craniofacial muscles, muscles that move the eyes, control facial expression and allow food uptake and speech, have long been regarded as a variation on the general body muscle scheme. However, evidence has accumulated that the function of head muscles, their developmental anatomy and the underlying regulatory cascades are distinct. This article reviews the key aspects of craniofacial muscle and muscle stem cell formation and discusses how this differs from the trunk programme of myogenesis; we show novel RNAseq data to support this notion...
