REVIEW
Anna Idelevich, Roland Baron
The brain, which governs most, if not all, physiological functions in the body, from the complexities of cognition, learning and memory, to the regulation of basal body temperature, heart rate and breathing, has long been known to affect skeletal health. In particular, the hypothalamus - located at the base of the brain in close proximity to the medial eminence, where the blood-brain-barrier is not as tight as in other regions of the brain but rather "leaky", due to fenestrated capillaries - is exposed to a variety of circulating body cues, such as nutrients (glucose, fatty acids, amino acids), and hormones (insulin, glucagon, leptin, adiponectin) [1-3]...

OBJECTIVE Rathke's cleft cysts (RCCs) are benign epithelial lesions of the sellar region typically treated via a transsphenoidal approach with cyst fenestration and drainage. At present, there is limited evidence to guide patient selection for operative treatment. Furthermore, there is minimal literature describing factors contributing to cyst recurrence. METHODS The authors conducted a retrospective analysis of 109 consecutive cases of pathology-confirmed RCCs treated via a transsphenoidal approach at a single center from 1995 to 2016...

Dorsal internal carotid artery (ICA) aneurysms are notorious for their high morbidity and mortality. They have an extremely fragile wall and have a high chance of rupture and clip slippage during the intraoperative and postoperative period. Strategies proposed to mitigate these problems encompass including part of the normal ICA wall in addition to neck of aneurysm in clip blades, as well as the use of encircling materials (silicon, cellulose, Weck's clip) over a clip. The Achilles' heel of the problem is to take an appropriate thickness of the normal ICA in clip blades...

Primary brain microvessels (BrMV) maintain the cellular characters and molecular signatures as displayed in vivo, and serve as a vital tool for biomedical research of the blood-brain barrier (BBB) and the development/optimization of brain drug delivery. The variations of relative purities or cellular composition among different BrMV samples may have significant consequences in data interpretation and research outcome, especially for experiments with high-throughput genomics and proteomics technologies. In this study, we aimed to identify suitable reference gene (RG) for accurate normalization of real-time RT-qPCR analysis, and determine the proper marker genes (MG) for relative purity assessment in BrMV samples...

Human-ether-a-go-go-related channel (hERG) is a voltage gated potassium channel (Kv 11.1) abundantly expressed in heart and brain tissues. In addition to playing an important role in mediation of repolarizing K+ currents (IKr ) in Action Potential (AP), hERG is notorious for its propensity to interact with various medications. The drug-induced block of K+ currents across hERG channel are strongly associated with dysrhythmic conditions collectively known as drug-induced long-QT-syndrome. The recent availability of the high-resolution Cryo-EM structures for the hERG channel has provided unique opportunity to resolve structural mechanisms involved into the process of voltage-gating of hERG channels, map various roles played by components of ventricular and neuronal membranes and then to connect it to cellular pathways through which diverse chemical compounds might be affecting function of the channel...

We experienced 2 cases of primary pulmonary vein stenosis(PVS),which developed after a bidirectional Glenn procedure was performed for complex heart defects with normal pulmonary venous return. Although the patients successfully underwent primary sutureless repair for left PVS, restenosis of the affected pulmonary veins occurred several months after surgery in both patients. Stent implantation followed by balloon angioplasty was performed for stent stenosis in 1 patient without effect. However, the patient later underwent a successful fenestrated Fontan procedure...

Superior canal semicircular dehiscence (SCCD) may cause vestibular and audiological symptoms that are sometimes debilitating. Computed tomography (CT) and the vestibular evoked myogenic potential (VEMP) test are essential for the diagnosis of SCCD. Various surgical techniques have been developed to manage SCCD but have many associated complications. Our technique uses an approach that otologists and surgeons are highly familiar with and that has other advantages, such as minimizing surgical trauma and preventing recurrences...

Foot drop (FD) is an uncommon manifestation of nerve root compression secondary to lumbar degenerative disease (LDD). In most of these patients, FD is unilateral and is associated with low back pain and leg pain. A small number of cases have been described with bilateral FD, which is reported to occur simultaneously in a synchronous fashion. A 63-year-old male with a remote history of spinal surgery due to left painless FD presented with a new episode of right FD, this new FD initiated suddenly and it was not associated with low back pain or radicular pain...

Current surgical dogma for infected aortic endografts consists of complete explantation concurrent with revascularization via extra-anatomic bypass or in situ infection-resistant conduit. However, this treatment paradigm is associated with high rates of postoperative mortality and major morbidity. Therefore, patients with prohibitive operative risk are often not offered surgical intervention. In the following manuscript, we report the successful treatment of an 85-year-old gentleman with a fenestrated aortic endograft (Cook Medical, Bloomington, Indiana) infected secondary to the formation of an aortoenteric fistula with primary bowel repair, washout, and lifelong antibiotics and followed for nearly 2 years after intervention...

INTRODUCTION: Gas gangrene is a rapidly progressive bacterial infection leading to necrosis that usually develops as a result of trauma or postoperative complications. This condition requires early diagnosis with immediate surgical intervention. With a poor prognosis, a high incidence of amputation, and comorbidities such as diabetes and peripheral vascular disease, patients with gas gangrene are put at further risk for surgical complications. OBJECTIVE: This case series reports the clinical outcomes of using a commercially available viable cryopreserved umbilical tissue (vCUT) in the surgical management of 10 patients (9 males, 1 female) with acute lower extremity gas gangrene...

A 64-year-old woman complaining of progressive dyspnea was admitted with recurrence of massive pericardial effusion. The patient had been diagnosed with radiation pericarditis based on a previous case of pericardiocentesis. To make a diagnosis and improve her symptoms, imaging examinations and pericardial fenestration were performed. Because of difficulty making a diagnosis, after some months, pericardiotomy and incision of the epicardium were performed. The patient was ultimately diagnosed with primary malignant pericardial mesothelioma of the epithelioid type...
