The angioplasty of chronic total aortoiliac occlusion using transfemoral is controversial. From March 2014 to December 2015, four consecutive patients (4 males; mean age 58.2±6.8 years; age of range 51-65 years) underwent angioplasty and stenting of TASC-D occlusion. In all the cases, we failed to cross from femoral approach. On switching over to left brachial access, angioplasty was done successfully in all. There was no procedural site complication or clinical evidence cerebral thromboembolism. Self-expandable stents were implanted in all with adequate pre and post dilation...

Single immediate implant replacement is accompanied by excellent survival rates and a favorable esthetic outcome. The objective of this report was to describe a surgical approach for removal of a buccal or palatally located impacted secondary canine, combined with extraction of the failing primary canine, and immediate placement and provisionalization of an implant. A window technique was applied for surgical removal of the impacted canine. The alveolar crest was preserved. After extraction of the primary canine, the implant was inserted with primary stability...

Poly(A) tail length and mRNA deadenylation play important roles in gene regulation. However, how they regulate embryonic development and pluripotent cell fate is not fully understood. Here we present evidence that CNOT3-dependent mRNA deadenylation governs the pluripotent state. We show that CNOT3, a component of the Ccr4-Not deadenylase complex, is required for mouse epiblast maintenance. It is highly expressed in blastocysts and its deletion leads to peri-implantation lethality. The epiblast cells in Cnot3 deletion embryos are quickly lost during diapause and fail to outgrow in culture...

We describe a successful transcatheter, transapical mitral valve implant within a failed mitral bioprosthesis (valve-in-valve) in a symptomatic 86-year-old patient with prohibitive surgical risks, using the new Sapien 3 balloon-expandable valve. Post-deployment echocardiographic profile of the valve-in-valve was satisfactory and the patient was discharged from hospital uneventfully. This is the first reported case of the Sapien 3 valve used in the mitral valve-in-valve setting.

AIM: This new laser facilitated 'inside-out' technique was used for transvenous pacemaker insertion in a pacemaker-dependent patient with bilateral subclavian occlusion and a failed epicardial system who is not suitable for a transfemoral approach. METHOD AND RESULTS: Procedure was undertaken under general anaesthesia with venous access obtained from right femoral vein and left axillary vein. 7F multipurpose catheter was used to enter proximal edge of the occluded segment of subclavian vein via femoral approach, which then supported stiff angioplasty wires and microcatheters to tunnel into the body of occlusion...

Intramedullary tibial fixation is a commonly used and highly successfully treatment in acute fractures, nonunion settings, and correctional procedures. In the setting of a nonunion, removal of a failed implant can add to operative time and surgeon frustration while further compromising bone in an area already at risk for failure. Here we present a technique, using readily accessible equipment, for removing a distal solid tibial nail fragment in a manner that preserves bone.

Transcatheter aortic valve (TAV) implantation within a failed bioprosthetic valve is a growing trend for high-risk patients. The non-compliant stent of the previous prosthesis may prevent full expansion of the TAV, which has been shown to distort the leaflet configuration, and has been hypothesized to adversely affect durability. In this study, TAV leaflet fatigue damage under cyclic pressurization in the setting of stent underexpansion by 0 (fully expanded), 1, 2 and 3 mm was simulated using finite element analysis to test this hypothesis...

BACKGROUND: Mucous retention cyst refers to a cyst made by expansion due to the blockage of the salivary gland near the maxillary sinus, and it is surrounded by epithelial cells. Most of them are small; therefore, they cannot be found well and are frequently with antral polyp. The aim of this study was to evaluate the clinical prognosis of sinus bone graft in patients with mucous retention cyst. METHODS: This study was performed retrospectively on 23 patients who had sinus bone graft...

PURPOSE: To report the outcome of graftless osteotome sinus floor elevation (OSFE) in order to evaluate whether apical bone gain depends on the initial residual bone height and whether the initial residual bone height has an influence on the amount of marginal bone loss. Furthermore the study aimed to assess if perforations of the Schneiderian membrane or residual bone height are potential predictors of implant survival. MATERIALS AND METHODS: In this retrospective study all patients were included who were treated between 2001 and 2010 and received dental implants in combination with OSFE in a private practice...

PURPOSE: To test the hypothesis that there is no difference in clinical, radiographic and aesthetic outcomes positioning single post-extractive ultra-wide 7 mm-diameter implants or waiting 4 months to place implant, after molar extraction and the socket preservation procedure. MATERIAL AND METHODS: Patients requiring one implant-supported single restoration to replace a failed tooth in the molar region of both maxilla and mandible were selected. Patients were randomised according to a parallel group design into two arms: implant installation in fresh extraction sockets augmented with corticocancellous heterologous bone and porcine derma (group A) or delayed implant installation 4 months after tooth extraction and socket preservation using the same materials (group B)...
