Myocardial bridges are anatomical entities characterized by myocardium covering segments of coronary arteries. In some patients, the presence of a myocardial bridge is benign and is only incidentally found on autopsy. In other patients, however, myocardial bridges can lead to compression of the coronary artery during systolic contraction and delayed diastolic relaxation, resulting in myocardial ischemia. This ischemia in turn can lead to myocardial infarction, ventricular arrhythmias and sudden cardiac death. Myocardial bridges have also been linked to an increased incidence of atherosclerosis, which has been attributed to increased shear stress and the presence of vasoactive factors. Other studies however, demonstrated the protective roles of myocardial bridges. In this study, using systematic review and a meta‐analytical approach we investigate the prevalence and morphology of myocardial bridges in both clinical imaging and cadaveric dissections. We also discuss the pathophysiology, clinical significance, and management of these anatomical entities.
Incidence of transexualism and request for neophalloplasty is increasing yielding a current prevalence of trans-male in the USA of 1:2500. Surgeons have explored various techniques to improve desirable outcomes of neophallic construction, decrease the length of surgery, and minimize stigmatizing scars. The anterolateral thigh (ALT) flap is an alternative to the traditional radial forearm flap for patients who do not want a forearm scar. Surgical text descriptions were enhanced by the creation of new anatomic illustrations. Anatomy of the donor and recipient sites as well as the surgical technique leading to creation of the neophallus are demonstrated in detail with new relevant illustrations. The ALT flap is a skin, fat and fascia flap that is usually supplied by the descending branch of the lateral circumflex femoral vessels and the lateral femoral cutaneous nerve. However, variability in neurovascular supply does exist with important clinical implications. In the pedicled surgical procedure, neurovascular supply is left partly attached to the donor site ("pedicle") and simply transposed to the perineum, keeping the pedicle intact as a conduit to supply the tissue with blood and innervation. ALT flap offers clinical advantages of less obvious donor site concealable with clothing, decreased surgical time, preservation of erogenous sensation and vascular supply of the flap without microsurgical anastomosis of nerves and vessels, and good potential for urethroplasty. This surgery may be difficult in patients with thicker skin and more subcutaneous thigh fat. Clin. Anat, 2017. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.
An estimated 1.4% of the population worldwide has been diagnosed with Gender Dysphoria, as defined by the Diagnostic and Statistical Manual of Mental Disorders. Gender reassignment, which holistically encompasses psychotherapy, hormonal therapy and genital and nongenital surgeries, is considered the most effective treatment for transgender nonconforming patients afflicted with gender dysphoria. Little research is currently available identifying the psychosocial needs of the transgender population and their access to preventative and primary care during this transitioning process. This article presents an overview of the evolution and current approaches to genital surgical procedures available for both male-to-female, as well as female-to-male gender-affirmation surgeries.

Trisomy 18 is the second most common aneuploidy after trisomy 21. Due to its multi-systemic defects, it has a poor prognosis with a 50% chance of survival beyond one week and a <10% chance of survival beyond one year of life. However, this prognosis has been challenged by the introduction of aggressive interventional therapies for patients born with trisomy 18. As a result, a review of the anatomy associated with this defect is imperative. While any of the systems can be affected by trisomy 18, the following areas are the most likely to be affected: craniofacial, musculoskeletal system, cardiac system, abdominal, and nervous system. More specifically, the following features are considered characteristic of trisomy 18: low-set ears, rocker bottom feet, clenched fists, and ventricular septal defect. Of particular interest is the associated cardiac defect, as surgical repairs of these defects have shown an improved survivability. In this article, the anatomical defects associated with each system are reviewed. Clin. Anat. 29:628-632, 2016. © 2016 Wiley Periodicals, Inc.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
