INTRODUCTION: Urinary incontinence in men after radical prostatectomy affects strongly quality of life. If conservative treatment fails, surgical treatment consists of implantable devices. If the requirement of manual dexterity in the artificial sphincter is to be avoided, the ProACT system offers a readjustable system, which shows good continence, but also high revision rates. Aim of our single-centre, single-surgeon study was to evaluate the success and revision rates of ProACT over long-term follow-up and if repeat ProACT implantation after failure would be a reasonable strategy...

Implant treatment is one of the most important surgical processes in teeth which reduces the difficulties in teeth by providing the interface between bone and jaw. The established implant treatment used to support the denture, bridge and teeth crown. Even though it supports many dental related activities, the successive measure of implant treatment is fail to manage because it fully depends on the patient's personal activities and health condition of mouth tissues. So, the successive rate of implant treatment process is identified by applying the memetic search optimization along with Genetic scale recurrent neural network method...

Recurrent implantation failure (RIF) is very distressing for couples and frustrating for their clinicians who seek to find a solution. RIF is defined as the failure to achieve a clinical pregnancy following the transfer of at least four good-quality embryos in a minimum of three fresh or frozen cycles in a woman of age below 40 years. An agreed local protocol regarding how couples with RIF should be further investigated and managed should be in place. Ovarian function should be assessed by measuring antral follicle count, FSH, and AMH...

Use of epidermal growth factor receptor (EGFR) inhibitors represented by gefitinib and erlotinib has become the standard of treatment for non-small-cell lung cancers (NSCLCs) with activating EGFR mutations. However, the majority of NSCLCs, which overexpress EGFR without such mutations, are resistant to EGFR inhibitors, and the mechanism(s) behind such primary resistance of NSCLCs without activating EGFR mutations to EGFR inhibitors still remains poorly understood. Here in this study, we show that glucose metabolism mediated by GLUT1, a facilitative glucose transporter, is involved in gefitinib resistance of NSCLC cells...

OBJECTIVE: Oral bacteria and periodontal pathogen have been predominantly linked with early- and late- stage failures of titanium (Ti) dental implants (DI) respectively. This study is based on the hypothesis that bacterial colonization can damage the surface oxide (TiO2 ) layer. Early-failed DI were compared with DI post-in vitro immersion in early colonizing oral bacteria; late failed DI were weighed against DI immersed in late colonizing anaerobic pathogens. METHODS: Retrieval analysis: Seven early- stage failed implants with five of them connected to healing abutments (HAs), and ten late- stage failed retrievals were subjected to surface analysis...

Following spinal cord stimulator (SCS) implantation, post-operative pain is commonly incisional or neuropathic from neurological damage. Occasionally, this new pain may mimic symptoms due to pre-existing pathology. We present a case of immediate, severe, post-operative leg pain secondary to a lower extremity deep vein thrombosis (DVT) and subsequent pulmonary embolism (PE) after percutaneous SCS implantation for failed back syndrome. The risk factors of DVT after spine surgery and perioperative prophylaxis will be further discussed with a brief literature review...

Background: Reinfected total knee arthroplasty can be managed with a second two-stage exchange or a knee arthrodesis procedure. Methods: Twenty-three patients with knee arthrodesis after failed exchange arthroplasty for infection were reviewed. Patients were managed with a staged protocol of implant extraction, débridement, and implantation of an antibiotic spacer, with subsequent arthrodesis. Follow-up averaged 40.4 months, with a minimum of 1 year. Results: Bony union with eradication of infection was achieved in 20/23 knees...

Background: Accessing the hippocampus for amygdalohippocampectomy and minimally invasive procedures, such as depth electrode placement, require an accurate knowledge regarding the location of the hippocampus. Methods: The authors removed 10 human cadaveric brains from the cranium and observed the relationships between the lateral temporal neocortex and the underlying hippocampus. They then measured the distance between the hippocampus and superficial landmarks. The authors also validated their study using magnetic resonance imaging (MRI) scans of 10 patients suffering from medial temporal lobe sclerosis where the distance from the hippocampal head to the anterior temporal tip was measured...

A 62-year-old man with effort angina underwent percutaneous coronary intervention in our hospital. The target lesion was severely calcified at the mid part of the right coronary artery. Pre-procedural intravascular imaging and optical frequency domain imaging showed a calcified nodule at the lesion. We performed rotational atherectomy with a 2.0 mm burr and observed an increase in the lumen area; however, a large amount of calcified nodule persisted. We decided to perform rotational atherectomy with a burr size of 2...

Valve-in-valve (ViV) procedures for failing bioprostheses carry a certain risk for device malfunction. We herein report a case of a failing Evolut R in a deteriorated Mitroflow, treated with a Sapien 3. An 81 year old female patient received surgical aortic valve replacement and was treated by ViV due to deterioration. Three years later, echocardiography revealed a pressure gradient of peak/mean 105/63 mmHg. Subsequently, a second ViV procedure with initial intentional rupture of the bioprosthetic stent was performed...

BACKGROUND: Earlier studies have reported both early morning and Monday peaks in occurrence of sudden cardiac arrest (SCA) in the community, and appropriate defibrillator shocks in patients with implantable cardioverter defibrillators (ICD). However, a more recent analysis of ICD shocks reported absence of these peaks. OBJECTIVE: To perform a contemporary evaluation of the circadian and septadian variation of SCA in the general population. METHODS: The analysis was performed from an ongoing, population-based study of SCA in a Northwestern US community of approximately one million residents...

In this review we summarize the current evidence and experience regarding the performance of SPECT/CT in the evaluation of patients with postoperative painful wrist or hand. There is a wide range of operative wrist and hand interventions due to congenital, traumatic, degenerative, or inflammatory diseases. A significant number of patients suffer from pain after operative procedures. Several imaging modalities have been used to evaluate the reason for painful postoperative wrists like standard conventional x-rays, ultrasound, CT, MRI, or bone scintigraphy...

BACKGROUND: A significant proportion of depressed patients fail to respond to treatment with antidepressant drugs. Such patients might nonetheless respond to deep brain stimulation of the prefrontal cortex. Deep brain stimulation has also been shown to normalize behaviour in the chronic mild stress (CMS) model of depression. However, these studies have involved animals that are in general treatment responsive. Thus, this is not the ideal situation in which to investigate how deep brain stimulation is effective where antidepressant drugs are not...
