OBJECTIVES: The best surgical strategy for acute Stanford Type A aortic dissection (aTAAD) involving the arch remains controversial. Here, we report on the satisfactory results following aTAAD repair using a novel arch fenestrated stent graft. METHODS: From December 2014 to December 2015, 42 aTAAD patients (27 male and 15 female) underwent ascending aorta replacement and fenestrated stent graft implantation. The fenestrated stent graft was implanted into the true lumen of the aortic arch and proximal descending aorta, with the fenestration opening located at the ostia of 3 head vessels in the arch...

OBJECTIVE: To define a map of interradicular spaces where miniscrew can be likely placed at a level covered by attached gingiva, and to assess if a correlation between crowding and availability of space exists. METHODS: Panoramic radiographs and digital models of 40 patients were selected according to the inclusion criteria. Interradicular spaces were measured on panoramic radiographs, while tooth size-arch length discrepancy was assessed on digital models. Statistical analysis was performed to evaluate if interradicular spaces are influenced by the presence of crowding...

Orthodontic treatments are usually performed using fixed brackets or removable oral appliances, which are traditionally made from alginate impressions and wax registrations. Among removable devices, eruption guidance appliances are used for early orthodontic treatments in order to intercept and prevent malocclusion problems. Commercially available eruption guidance appliances, however, are symmetric devices produced using a few standard sizes. For this reason, they are not able to meet all the specific patient's needs since the actual dental anatomies present various geometries and asymmetric conditions...

Skeletal deformities in farmed fish are a recurrent problem. External malformations are easily recognized, but there is little information on how external malformations relate to malformations of the axial skeleton: the external phenotype-skeleton link. Here, this link is studied in post-hatch to first-feed life stages of Chinook salmon (Oncorhynchus tshawytscha) raised at 4, 8 and 12°C. Specimens were whole-mount-stained for cartilage and bone, and analysed by histology. In all temperature groups, externally normal specimens can have internal malformations, predominantly fused vertebral centra...

PURPOSE: To date, many radiographic parameters on patellar instability have their measurements taken statically, and have not been studied in various degrees of flexion according to the patellar tracking. There are also limited data regarding the use of these parameters in predicting recurrent patellar dislocation. The current study aims to review the radiographic parameters of the patellofemoral joint in different degrees of knee flexion and to correlate them with the presence of recurrent instability...

Elastofibroma dorsi (ED) is an uncommon benign soft tissue tumor with an uncertain pathogenesis. It mostly occurs in the infrascapular region of elderly people with a female predominance. Typically bilateral, ED can also be unilateral. While many patients remain asymptomatic, ED can be responsible of a periscapular arch source of ache. The diagnosis of ED is set on magnetic resonance imaging, and the pathological study ensures the diagnosis after surgical excision and establishes the differential diagnosis with malignant neoplasic process...

Patients with interstitial cystitis/bladder pain syndrome (IC/BPS) suffer from chronic pain that severely affects quality of life. Although the underlying pathophysiology is not well understood, inhibition of bladder sensory afferents temporarily relieves pain. Here, we explored the possibility that optogenetic inhibition of nociceptive sensory afferents could be used to modulate bladder pain. The light-activated inhibitory proton pump Archaerhodopsin (Arch) was expressed under control of the sensory neuron-specific sodium channel (sns) gene to selectively silence these neurons...

For many years, it has been considered necessary to restore posterior support with a bilateral free-end saddle when a full upper denture is opposed by a shortened dental arch. It was thought that this would provide occlusal stability and prevent anterior bite collapse and temporomandibular dysfunction. As free-end saddle partial dentures are often poorly tolerated by patients, this case study tests whether a retentive full-upper denture occluding with a shortened dental arch offers enough to fulfil a patient’s needs...

INTRODUCTION: Prostate hypertrophy, median lobe hypertrophy, and pubic arch interference (PAI) are relative contraindications to brachytherapy because of potential morbidity and technical considerations. GnRH analogs or non-steroidal anti-androgens are currently utilized to achieve prostatic downsizing prior to brachytherapy. However, such agents have been associated with effects on body habitus, metabolism, and quality of life. In contrast, 5-alpha reductase inhibitors (5-ARI) are far less frequently associated with these morbidities...

A novel custom-made E-Vita Open prosthesis (JOTEC GmbH, Hechingen, Germany) has been designed with 2 additional side branches. The first one, the reperfusion branch, allows distal aortic perfusion after the collar anastomosis of a frozen elephant trunk repair has been performed. The second one, the debranching branch, permits reimplantation of any configuration of supraaortic debranching to the dacron graft. This modified graft provides two main advantages: first, combined with prior carotid-subclavian bypass and bilateral axillary perfusion, it allows continuous bihemispheric antegrade perfusion and arch-first technique under mild hypothermia (32°C); second, it grants distal aortic reperfusion after distal anastomosis completion performed under moderate hypothermia (28°C)...

The reattachment of the supra-aortic vessels during hybrid arch repair using a branched prosthesis is time consuming and sometimes technically challenging. Here, we describe the surgical technique of bridging the end-to-end anastomoses between the graft branches and the supra-aortic vessels by self-expanding covered stents to reduce suturing time, avoid anastomotic bleeding, enhance true lumen remodeling, and improve vessel alignment to the hybrid graft.

Background: Heparan sulfate proteoglycan (HSPG) syndecan-1 (Sdc1) acts as a receptor for triglyceride-rich lipoproteins (TRLs), growth factors, chemokines and enzymes. Due to the disordered structure, its function is as diverse as its ligands. In this paper, we have analyzed hepatic and aortic arch expression of Sdc1 in ApoE(-/-) mice and examined their association with biochemical changes in plasma during the atheroma formation. Methods: ApoE knockout (ApoE(-/-)) mice as a model of atherosclerosis were used...

Pradeep Jain, Pallav Patni, Pant Yogesh, Vyas Anup
The endodontic treatment of maxillary third molar often poses a challenge even to an experienced endodontist because of their most posterior location in the dental arch, aberrant occlusal anatomy, abnormal root canal configuration and eruption patterns. Owing to these anatomical limitations, their extraction remains the treatment of choice for many clinicians. As we know, retaining every functional component of the dental arch is of prime importance in contemporary dental practice. This clinical case report aims to discuss the endodontic treatment of maxillary third molar with MB2 root canal separated throughout the length and exit at two separate apical foramina (Vertucci type IV) diagnosed with Cone Beam Computed Tomography (CBCT)...
