Minimally invasive atrial septal defect closure and tricuspid annuloplasty in female patients are normally performed through a right submammary anterior minithoracotomy approach. However, when the aortic root is located higher, the direction of aortic cannulation becomes not ideal through the submammary incision. In such cases, transareolar approach is useful. Through this approach, aortic cannulation and tricuspid operation can be performed with endoscopic assistance, and ASD closure can be performed under direct vision...

In clinical practice, Osteopaths and Manual Therapists commonly direct treatment towards the diaphragm by the use of a 'Diaphragm Release'. Currently, there is paucity within the literature to support the use of this technique, specifically in pain outcomes. This research aims to support a neurophysiological mechanism based upon the osteopathic principle "The body is a unit". Demonstrating that directing treatment to distal tissue which is neurologically related can reduce pain in the originating spinal segments...

Background: The presence of extracranial carotid disease (ECD) is associated with less favorable clinical outcomes a in patients with acute ischemic stroke caused by intracranial proximal occlusion. Acute intra-arterial treatment (IAT) in the setting of extracranial and intracranial lesions is considered challenging, and whether it yields improved outcomes remains uncertain. Objective: To examine whether the presence of ECD modified the effect of IAT for intracranial proximal anterior circulation occlusion...

It is estimated that 2% to 4% of the US population will seek treatment for temporomandibular joint (TMJ) symptoms, typically occurring with anterior disc displacement. The temporomandibular retrodiscal tissue (RDT) has been postulated to restrict pathologic disc displacement. To elucidate RDT function, understanding regional RDT biomechanics and ultrastructure is required. No prior biomechanical analysis has determined regional variations in RDT properties or associated biomechanical outcomes with regional variations in collagen and elastin organization...

NEW PATHOPHYSIOLOGICAL INSIGHTS: Based on improved knowledge of the vascular supply of the proximal femur, a safe surgical dislocation of the hip joint was established allowing direct insights to the pathomorphological malfunctioning of the joint. One insight was that slipped capital femoral epiphysis (SCFE) impingement leads to substantial damage of the chondrolabral rim area, even in the presence of minor slips. A further surgical development was the extended retinacular flap allowing for correction of the deformity with calculable risk for iatrogenic necrosis...

INTRODUCTION: Severe post-traumatic ankle arthritis poses a reconstructive challenge in young and active patients. Although technically demanding and despite unsolved immunological issues, bipolar fresh total osteochondral allograft (BFTOA) represent an intriguing option to arthrodesis and prosthetic replacement. The purpose of this paper is to evaluate the outcomes of a series of 48 ankle BFTOA at 10 years follow up and to investigate the rate of survival long term. METHODS: 58 patients underwent BFTOA, of these 48 were available for follow up...

5-Aminolevulinic acid (5-ALA) fluorescence-guided surgery is widely used for detection and planning of resection of malignant gliomas and other brain tumors. However, no reports have described 5-ALA fluorescence-guided surgery or direct visualization of germ cell tumors. Here, we report two cases of germ cell tumors in which a positive 5-ALA fluorescent signal was visualized with a neuroendoscope. Both cases had a tumor in the pineal region that was associated with hydrocephalus. The patients underwent surgery after administration of 5-ALA...

Data from randomized clinical trials and current guidelines suggest that patients with anterior circulation occlusion with contraindications to intravenous thrombolysis may benefit from direct mechanical thrombectomy. Nevertheless, no data are available on the efficacy and safety of direct mechanical thrombectomy in patients with concomitant spontaneous intracerebral hemorrhage. We report the case of a 51-year-old woman with a spontaneous intracerebral hemorrhage in the right parietal and occipital lobes, who experienced, 7 days later, an occlusion of the proximal left middle cerebral artery...

Contextual relevance, which is vital for understanding conversational implicatures (CI), engages both the frontal-temporal language and theory-of-mind networks. Here we investigate how contextual relevance affects CI processing and regulates the connectivity between CI-processing-related brain regions. Participants listened to dialogues in which the level of contextual relevance to dialogue-final utterance (reply) was manipulated. This utterance was either direct, indirect but relevant, irrelevant with contextual hint, or irrelevant with no contextual hint...

For decades, it was commonly thought that the bilateral heart fields in the early embryo fold directly toward the midline, where they meet and fuse to create the primitive heart tube. Recent studies have challenged this view, however, suggesting that the heart fields fold diagonally. Since early foregut and heart tube morphogenesis are intimately related, this finding also raises questions concerning the traditional view of foregut formation. Here, we combine experiments on chick embryos with computational modeling to explore a new hypothesis for the physical mechanisms of heart tube and foregut formation...

The inter-lamellar matrix (ILM) -located between adjacent lamellae of the annulus fibrosus- consists of a complex structure of elastic fibres, while elastic fibers of the intra-lamellar region are aligned predominantly parallel to the collagen fibers. The organization of elastic fibres under low magnification, in both inter- and intra-lamellar regions, was studied by light microscopic analysis of histologically prepared samples; however, little is known about their ultrastructure. An ultrastructural visualization of elastic fibres in the inter-lamellar matrix is crucial for describing their contribution to structural integrity, as well as mechanical properties of the annulus fibrosus...

Background: Psychostimulants such as methylphenidate (MPH) and modafinil are increasingly used by healthy people for cognitive enhancement purposes, whereas the acute effect of 3,4-methylenedioxymethamphetamine (MDMA, ecstasy) on cognitive functioning in healthy subjects remains unclear. This study directly compared the acute effects of MPH, modafinil and MDMA on the neural mechanisms underlying response inhibition in healthy subjects. Methods: Using a double-blind within-subject placebo-controlled cross-over design, MPH, modafinil and MDMA were administrated to 21 healthy subjects, while performing a Go/No-Go event-related functional magnetic resonance imaging task to assess brain activation during motor response inhibition...

Placement of a ventricular catheter is the most common and easiest procedure in neurosurgery. Usually, the procedure is performed using anatomical landmarks. However, despite the apparent ease of this manipulation, its results are not always satisfactory. According to the literature data, the rate of improperly placed ventricular catheters amounts to 10-40%, which is directly correlated with the risk of shunt dysfunction. The use of special equipment, such as ultrasound scanners, endoscopes, stereotactic devices, and neuronavigation systems, significantly increases success of surgery...
