Slow ventricular tachycardia (VT) in patients with devices such as an implantable cardioverter - defibrillator (ICD) is more common than in the rest of the population. The incidence in elderly patients with an ICD remains largely unknown. In younger patients, slow VT is generally asymptomatic or associated with limited clinical relevance. It may be efficiently and safely terminated by anti-tachycardia pacing. We present a case of slow VT in a 91-year-old man with ICD with type 1 acute respiratory failure and drowsiness...

High endometrial receptivity in the window of implantation (WOI) is essential for successful implantation. However, a diagnostic tool with high specificity for impaired endometrial receptivity remains to be developed. We collected endometrium specimens during the WOI from patients with RIF and women who conceived after one IVF/ICSI attempt. We conducted mRNA microarray on the samples followed by relevant comparative and functional analysis. Microarray analysis revealed 357 dysregulated mRNAs between the two groups...

Reproductive failure in humans is a very important social and economic problem, because nowadays women decide to conceive later in life and delay motherhood. Unfortunately, with increasing age they have less chance for natural fertilization and maintenance of pregnancy. Many of them need assisted reproductive technology. Approximately 10% of women after in vitro fertilization-embryo transfers experience recurrent implantation failure (RIF). Multiple factors may contribute to RIF, including oocyte and sperm quality, parental chromosomal anomalies, genetic or metabolic abnormalities of the embryo, poor uterine receptivity, immunological disturbances in the implantation site, and some gynecologic pathologies such as endometriosis, uterine fibroids, hydrosalpinx and endometrial polyps...

BACKGROUND: Flexion and compression forces to the trunk can cause severe instability of the vertebral column and the anterior chest wall, mostly associated with an unstable fracture of the sternum. In combination, the worst case would be a complete disruption of the trunk. Some authors consider the sternum-rib-complex to be the fourth vertebral column. This study discusses the possibilities to treat instable trunk injuries with sternal fractures concomitant to vertebral spine fractures through anterior sternal plating employing a locked plate osteosynthesis in a low profile design instead of the use of bulky implants...

Bony reconstruction of the mandible after surgical resection results in improved rehabilitation and aesthetics. Composite tissue transfer has transformed reconstruction, particularly in patients who have received radiotherapy. However, there is morbidity related to free tissue transfer. Free nonvascularized bone grafts have much lower morbidity. Surgeons believe that free bone grafts greater than 6.0 cm are prone to failure. The aims of this study was to assess whether bone grafts greater than 6.0 cm in length have a high risk of failure...

Left ventricular assist device (LVAD) is one of the modern management therapies in patients with advanced heart failure, and it serves as a bridge to heart transplantation or even as destination therapy. However, it is burdened with a high risk of thromboembolic, hemorrhagic, and infectious complications despite prophylactic management. Splenic abscesses, as septic complications following implantation of mechanical ventricular support, have not yet been described in the literature. We report of a patient with severe left ventricular insufficiency (NYHA II/III), pulmonary hypertension, and arrhythmia who underwent implantation of the Heart Ware® pump for left ventricular support with simultaneous tricuspidvalvoplasty, as a bridge therapy to heart transplantation...

BACKGROUND: Research on the correlation of serum bilirubin level with cardiac function as well as outcomes in heart failure patients with cardiac resynchronization therapy (CRT) has not yet been reported. The aim of this study was to analyze the relationship between change in serum bilirubin level and left ventricular reverse remodeling, and also to clarify the impact of bilirubin change on clinical outcomes in CRT patients. METHODS: We evaluated 105 consecutive patients who underwent CRT...

BACKGROUND: Although the majority of Class III congestive heart failure (HF) patients treated with cardiac resynchronization therapy (CRT) show a clinical benefit, up to 40% of patients do not respond to CRT. This paper reports the design of the MultiPoint Pacing (MPP) trial, a prospective, randomized, double-blind, controlled study to evaluate the safety and efficacy of CRT using MPP compared to standard biventricular (Bi-V) pacing. METHODS: A maximum of 506 patients with a standard CRT-D indication will be enrolled at up to 50 US centers...

Dental implants interact with the jawbone through their common interface. While the implant is an inert structure, the jawbone is a living one that reacts to mechanical stimuli. Setting aside mechanical failure considerations of the implant, the bone is the main component to be addressed. With most failure criteria being expressed in terms of stress or strain values, their fulfillment can mean structural flow or fracture. However, in addition to those effects, the bony structure is likely to react biologically to the applied loads by dissolution or remodeling, so that additional (strain-based) criteria must be taken into account...

Advanced cancer induces fundamental changes in metabolism and promotes cardiac atrophy and heart failure. We discovered systemic insulin deficiency in cachectic cancer patients. Similarly, mice with advanced B16F10 melanoma (B16F10-TM) or colon 26 carcinoma (C26-TM) displayed decreased systemic insulin associated with marked cardiac atrophy, metabolic impairment, and function. B16F10 and C26 tumors decrease systemic insulin via high glucose consumption, lowering pancreatic insulin production and producing insulin-degrading enzyme...

The purpose of this study is to compare the results of 2 techniques, tension band wiring (TBW) and fixation with screws, in olecranon fractures in children affected with osteogenesis imperfecta (OI) type I. Between 2010 and 2014, 21 olecranon fractures in 18 children with OI (average age: 12 years old) were treated surgically. Ten patients were treated with the screw fixation and 11 with TBW. A total of 65% of olecranon fractures occurred as a result of a spontaneous avulsion of the olecranon during the contraction of the triceps muscle...

We introduce an implantable intracardiac soft robotic right ventricular ejection device (RVED) for dynamic approximation of the right ventricular (RV) free wall and the interventricular septum (IVS) in synchrony with the cardiac cycle to augment blood ejection in right heart failure (RHF). The RVED is designed for safe and effective intracardiac operation and consists of an anchoring system deployed across the IVS, an RV free wall anchor, and a pneumatic artificial muscle linear actuator that spans the RV chamber between the two anchors...

INTRODUCTION: Replacement of missing teeth by dental implants is one of the most common methods employed these days. Because of significant advancement in the design of implants and modifications in the procedure of dental implant surgery, the survival rate of the dental implants has reached up to approximately 95%. Osseointegration is one of the important factors affecting the survival of dental implants. Apart from these, the body's physiologic alterations can also predispose the dental implants for failure...

OBJECTIVE: Pauwels III femoral neck fractures are highly unstable. These fractures are commonly treated with three cannulated screws or sliding hip screw (SHS) implants, however high rates of non-union persist. A hybrid SHS construct has recently been proposed. The objective of the study was to compare this construct to the familiar inverted triad of cannulated screws and to a single SHS. METHODS: Fourth generation biomechanical femur analogs were used to create a highly repeatable injury model...

Repeat cardiac surgery in patients with a previous sternotomy is associated with significant morbidity and mortality. While transcatheter aortic valve implantation in high risk surgical patients is now well established, experience with transcatheter mitral valve replacement is still at an early stage. Although many successful reports of transcatheter mitral valve replacements now exist, the predominant approach has been via a transapical approach. It is likely that, as with the evolution of favoured access routes for transcatheter aortic therapies, future directions for transcatheter mitral valves will focus on smaller delivery systems favouring the transvenous transseptal approach where possible...
