Musculoskeletal Ultrasound
As we prepare this Ultrasound Clinics issue on Musculoskeletal Ultrasound, the 2012 Olympic Games in London are running and the world is watching with enthusiasm and admiration. In the background, collectively, millions of hours of training are evident. Sports are a dangerous activity, leading in many cases to injuries of every kind. Not long ago there was no place for ultrasound in the diagnostic battery. Since then, the development of high-resolution multifrequency linear transducers together with the knowledge and skills of ultrasound operators have brought this modality into wide use, making it the first imaging choice...

An analytical Micro CT methodology for quantifying inorganic dentine debris following internal tooth preparation
Conclusions This work presents a new approach for distinguishing between debris and structural inorganic tissue in root canals of teeth. The application may prove useful in other calcified tissue shape determination. Clinical significance remaining debris may contain bacteria and obstruct the flow of irrigating solutions into lateral canal anatomy. This new approach for detecting the amount of remaining debris in canal systems following instrumentation provides a clearer methodology of the identification of such debris.

Surface anatomy of the pulmonary fissures determined by high‐resolution computed tomography
Abstract The aim of our study was to describe the surface anatomy of the interlobar fissures using volumetric thin‐section high‐resolution computed tomography (HRCT). Retrospective assessment of HRCT examinations of 250 patients was performed. The localization of the oblique fissures was marked at three sites: posteriorly at its most superior medial limit, laterally in the midaxillary line, and inferiorly at the junction of the middle and lateral thirds of the hemithorax; posteriorly and laterally, this was to the nearest rib whilst inferiorly the position was described in relation to the diaphragm or chest wall. The l...

In Regard to Yang et al
To the Editor: The article by Yang et al describes an interesting approach for markerless lung tumor detection and tracking in cone beam computed tomography (CBCT) projections, using prior CT information to remove overlying anatomy signals. The proposed method is strikingly similar to the CT-based contrast-enhancement technique that we described previously , although some differences are evident. The authors obtain the “anatomy-without-tumor” dataset from the CT volume by masking the tumor with the average lung tissue value. We proposed the masking not only of the lesion but of the whole lung region, because simply ma...

Mitral valve prolapse: role of 3D echocardiography in diagnosis
Purpose of review: To review the utility and the latest developments in three-dimensional (3D) echocardiography of mitral valve prolapse. Recent findings: Although 3D echocardiography was invented in 1974, it did not gain wide clinical acceptance until the introduction of real-time 3D echocardiography in the first decade of the 21st century. Driven by improvements in probe technology and increases in computing power, 3D echocardiography now provides unprecedented images of mitral valve prolapse and its associated mitral regurgitation with no or minimal requirements for image post processing. Summary: 3D echocardiography ha...

Hypertrophic Cardiomyopathy: Refining the Lens of Cardiac Magnetic Resonance to Evaluate Late Gadolinium Enhancement⁎
Hypertrophic cardiomyopathy (HCM) is the most common inheritable cardiomyopathy, affecting about 1 in 500 individuals. Echocardiography is most commonly used for diagnosis and the diagnostic criteria are quite straightforward: abnormally increased thickness of the left ventricular (LV) wall in the absence of other causes of hypertrophy. Indeed, there are few other myocardial diseases for which such a “simple” anatomic measurement seems sufficient for diagnosis. However, sophisticated new imaging methods have the potential to move well beyond anatomy alone for the assessment of HCM.

Micro‐Computed Tomography for Visualizing Limb Skeletal Regeneration in Young Xenopus Frogs
Abstract For studies of vertebrate limb regeneration it is often desirable to visualize the regenerated skeleton, which is mostly cartilage, and also section the specimen for histological or immunohistochemical visualization of other tissues. However, the normal skeletal staining techniques are incompatible with immunohistochemistry. Here, we describe a contrast‐based micro‐computed tomography (microCT) method for direct and nondestructive observation of regenerated cartilage spikes in Xenopus frog limbs. In addition, we show that contrast based microCT imaging is compatible with immunohistochemistry protocols. This ap...

Early Regulation of Axolotl Limb Regeneration
Abstract Amphibian limb regeneration has been studied for a long time. In amphibian limb regeneration, an undifferentiated blastema is formed around the region damaged by amputation. The induction process of blastema formation has remained largely unknown because it is difficult to study the induction of limb regeneration. The recently developed accessory limb model (ALM) allows the investigation of limb induction and reveals early events of amphibian limb regeneration. The interaction between nerves and wound epidermis/epithelium is an important aspect of limb regeneration. During early limb regeneration, neurotrophic fac...

A Histological Comparison of the Original and Regenerated Tail in the Green Anole, Anolis carolinensis
This study provides a histological comparison of the mature regenerated and original tail of the lizard Anolis carolinensis. These data will provide a framework for future studies of this emerging model organism whose genome was recently published. This study demonstrated that the cartilage skeleton of the regenerated tail enclosed a spinal cord with an ependymal core, but there was no evidence that dorsal root ganglia or peripheral nerves are regenerated. The cartilage tube contained foramina that allowed the vasculature to cross, but was otherwise a rigid structure. The original tail has muscle groups arranged in quadran...

Transgenic Analysis of Signaling Pathways Required for Xenopus Tadpole Spinal Cord and Muscle Regeneration
Abstract The Xenopus tadpole has the capacity fully to regenerate its tail after amputation. Previously, we have established that this regeneration process requires the operation of several signaling pathways including the bone morphogenic protein, Wnt, and Fgf pathways. Here, we have addressed the signaling requirements for spinal cord and muscle regeneration in a tissue‐specific manner. Two methods were used namely grafts of transgenic spinal cord to a wild type host, and the use of the Tet‐on conditional transgenic system to express inhibitors in the individual tissues. For the grafting experiments, the tail was amp...

The Developing Xenopus Limb as a Model for Studies on the Balance between Inflammation and Regeneration
Abstract The roles of inflammation and immune cell reactivity triggered by amputation have only recently begun to be addressed in investigations of epimorphic regeneration, although studies of tissue repair in mammals clearly show the importance of the immune system in determining the quality of the repair process. Here, we first review inflammation‐related work in non‐mammalian systems of epimorphic regeneration which suggests that regeneration of an amputated appendage requires continuous modulation of the local immune response, from the first hours after amputation through the period of blastema patterning. We then ...

Transducing Bioelectric Signals into Epigenetic Pathways During Tadpole Tail Regeneration
Abstract One important component of the cell–cell communication that occurs during regenerative patterning is bioelectrical signaling. In particular, the regeneration of the tail in Xenopus laevis tadpoles both requires, and can be initiated at non‐regenerative stages by, specific regulation of bioelectrical signaling (alteration in resting membrane potential and a subsequent change in sodium content of blastemal cells). Although standing gradients of transmembrane voltage and ion concentration can provide positional guidance and other morphogenetic cues, these biophysical parameters must be transduced into transcripti...

Scar‐Free Wound Healing and Regeneration Following Tail Loss in the Leopard Gecko, Eublepharis macularius
In this study, we used the leopard gecko, Eublepharis macularius, to investigate and compare wound healing and regeneration following autotomy at a fracture plane and amputation outside the fracture plane. Both forms of tail loss undergo a nearly identical sequence of events leading to scar‐free wound healing and regeneration. Early wound healing is characterized by transient myofibroblasts and the formation of a highly proliferative wound epithelium immunoreactive for the wound keratin marker WE6. The new tail forms from what is commonly referred to as a blastema, a mass of proliferating mesenchymal‐like cells. Blaste...

Influence of a fabella in the gastrocnemius muscle on the common fibular nerve in Japanese subjects
Abstract The fabella is a sesamoid bone located in the proximal tendon of the gastrocnemius muscle. In rare cases, its presence may lead to a variety of clinical problems, including fabella syndrome and common fibular (CF) nerve palsy. The purpose of this study was to analyze the morphology of the fabella and CF nerve and discuss the influence of any existing fabellae on the size of the CF nerve. The morphology of the fabella and CF nerve in the popliteal region of the lateral head of the gastrocnemius muscle was investigated in 102 knees of 51 Japanese cadavers.

Evidence to support that adventitial cysts, analogous to intraneural ganglion cysts, are also joint‐connected
Abstract Cystic adventitial disease (CAD) is a rare condition in which cyst is found within a vessel, typically producing symptoms of vascular compromise. Most commonly located in the popliteal artery near the knee, it has been reported in arteries and veins throughout the body. Its pathogenesis has been poorly understood and various surgical approaches have been recommended. We extrapolated some recent information about a similar condition, intraneural ganglion cyst affecting the deep fibular (peroneal) nerve, to the prototype, CAD of the popliteal artery. In intraneural ganglion cysts affecting the deep fibular nerve we ...

Popliteal vessel injuries: complex anatomy, difficult problems and surgical challenges
Abstract The incidence of popliteal vessel injuries is low, even in busy urban trauma centers. As a result of this fact, few trauma centers and trauma surgeons have developed extensive experience in the management of these injuries. Popliteal vessel injuries in both civilian and military arenas incur significant morbidity. These injuries present a difficult challenge, and, although the overall incidence of these injuries remains low, the sequelae can be devastating. Successful outcomes for limb salvage and survival result from early recognition and rapid surgical intervention by a multidisciplinary approach ...

Can Bronchoscopic Airway Anatomy Be an Indicator of Autism?
Abstract Bronchoscopic evaluations revealed that some children have double branching of bronchi (designated "doublets") in the lower lungs airways, rather than normal, single branching. Retrospective analyses revealed only one commonality in them: all subjects with doublets also had autism or autism spectrum disorder (ASD). That is, 49 subjects exhibited the presence of initial normal anatomy in upper airway followed by doublets in the lower airway. In contrast, the normal branching pattern was noted in all the remaining 410 subjects who did not have a diagnosis of autism/ASD. We propose that the presence of double...

Gerbode-type left ventricular outflow tract to right atrial fistula complicating prosthetic aortic valve replacement identified by cardiac computed tomographic angiography
Abstract: Acquired left ventricular-right atrial communication ( Gerbode-type defect) is a rare complication of infective endocarditis. Although transesophageal echocardiography remains the technique of choice for the evaluation of complications of endocarditis this case highlights the usefulness of cardiac computed tomography in this scenario, particularly in cases where assessment of coronary anatomy is required before surgery.

Anatomy of the Biceps Tendon: Implications for Restoring Physiological Length-Tension Relation During Biceps Tenodesis With Interference Screw Fixation
Conclusions: This study provides guidelines for restoring the normal length-tension relation during biceps tenodesis with interference screw fixation. The simplest way to restore this relation is with tenodesis adjacent to the humeral head AM and a bone socket of 25 mm in depth. For tenodesis at more distal locations, both the length of the BT and the depth of the bone socket must be considered. Clinical Relevance: Information about the normal BT may be useful in preserving the physiological length-tension relation during biceps tenodesis.

Late Outcomes in Patients Undergoing Aortopulmonary Window for Pulmonary Atresia/Stenosis and Major Aortopulmonary Collaterals [ORIGINAL ARTICLES: PEDIATRIC CARDIAC]
Conclusions The data demonstrate that patients can undergo creation of an aortopulmonary window with excellent early results. Few patients were amenable to complete repair at the second operation, and most required multiple reoperations to recruit sufficient arborization. We interpret these counterintuitive results to suggest that hypoplastic central pulmonary arteries and diminished pulmonary blood flow are markers for a less well developed pulmonary vascular bed.

Open, Hybrid, and Endovascular Treatment for Aortic Coarctation and Postrepair Aneurysm in Adolescents and Adults [ORIGINAL ARTICLES: ADULT CARDIAC]
Conclusions Coarctation, recurrent coarctation, and postrepair aneurysm/pseudoaneurysm in adolescent and adult patients can be safely and effectively managed with open, hybrid, or endovascular techniques. Optimal results are achievable in this complex population of patients with a multimodality approach tailored to surgical indication and anatomy. All survivors of coarctation repair require lifelong surveillance.
