Although osteoporotic bone, with low bone mass and deteriorated bone architecture, provides a less favorable mechanical environment than healthy bone for implant fixation, there is no general agreement on the impact of osteoporosis on peri-implant bone (re)modeling, which is ultimately responsible for the long term stability of the bone-implant system. Here, we inserted an implant in a mouse model mimicking estrogen deficiency-induced bone loss and we monitored with longitudinal in vivo micro-computed tomography the spatio-temporal changes in bone (re)modeling and architecture, considering the separate contributions of trabecular, endocortical and periosteal surfaces...

The management of heart failure patients presenting in a moribund state remains challenging, despite significant advances in the field of ventricular assist systems. Bridge to decision involves using temporary devices to stabilize the hemodynamic state of such patients while further assessment is performed and a decision can be made regarding patient management. We developed a new temporary left ventricular assist system employing a disposable centrifugal pump with a hydrodynamically levitated bearing. We used three adult goats (body weight, 58-68 kg) to investigate the 30-day performance and hemocompatibility of the newly developed left ventricular assist system, which included the pump, inflow and outflow cannulas, the extracorporeal circuit, and connectors...

Peter Szurman
Pars plana vitrectomy combined with an endotamponade is the most important concept in retinal detachment surgery. Numerous advances in techniques and tamponade materials have been made, but the general problems of retinal detachment surgery are still unsolved: The primary success rate is not adequate, and there is no adequate strategy to address proliferative vitreoretinopathy, multiple retinal breaks or persistent hypotony. The story of tamponades is full of myths and misunderstandings. A critical review shows that tamponades have only a minor role in the history of retinal detachment surgery...

BACKGROUND: Fifteen to twenty percent of patients with locally advanced rectal cancer have a clinical complete response after chemoradiation therapy. These patients can be offered nonoperative organ-preserving treatment, the so-called watch-and-wait policy. The main goal of this watch-and-wait policy is an anticipated improved quality of life and functional outcome in comparison with a total mesorectal excision, while maintaining a good oncological outcome. OBJECTIVE: The aim of this study was to compare the quality of life of watch-and-wait patients with a matched-controlled group of patients who underwent chemoradiation and surgery (total mesorectal excision group)...

Because of the enormous advances in the medical treatment of CHD, the long-term survival of patients suffering from this disease has increased significantly. Currently, about 90% of patients reach adulthood, which entails many new challenges both for patients and their families and for healthcare professionals. The main objective of family-centred psychosocial care is to strengthen the emotional resilience of chronically ill patients and their families by adopting a holistic approach. During the biannual meeting of the psychosocial working group in 2012, participants expressed the need for general European guidelines...

OBJECTIVE: We sought to evaluate the risk and image quality from cardiovascular CT in patients across all stages of single-ventricle palliation, and to define accuracy by comparing findings with intervention and surgery. METHODS: Consecutive CT scans performed in patients with single-ventricle heart disease were retrospectively reviewed at a single institution. Diagnosis, sedation needs, estimated radiation dose, and adverse events were recorded. Anatomical findings, image quality (1-4, 1=optimal), and discrepancy compared with interventional findings were determined...

Daniel F Pease, Robert A Kratzke
The limited effectiveness of conventional therapy for malignant pleural mesothelioma demands innovative approaches to this difficult disease. Even with aggressive multimodality treatment of surgery, radiation, and/or chemotherapy, the median survival is only 1-2 years depending on stage and histology. Oncolytic viral therapy has emerged in the last several decades as a rapidly advancing field of immunotherapy studied in a wide spectrum of malignancies. Mesothelioma makes an ideal candidate for studying oncolysis given the frequently localized pattern of growth and pleural location providing access to direct intratumoral injection of virus...

BACKGROUND: The unmet burden of surgical disease represents a major global health concern, and a lack of trained providers is a critical component of the inadequacy of surgical care worldwide. Competency-based training has been advanced in high-income countries, improving technical skills and decreasing training time, but it is poorly understood how this model might be applied to low- and middle-income countries. We describe the development of a competency-based program to accelerate specialty training of in-country providers in cleft surgery techniques...

BACKGROUND: Despite requiring successful trials prior to implantation, spinal cord stimulation (SCS) systems for pain are often later removed. Removing surgically implanted hardware subjects patients to the risks and discomfort of a second surgery, threatens the cost-effectiveness of SCS, and limits the perceived durability of SCS technology for pain problems. OBJECTIVE: To investigate patterns of reasons given among patients who underwent SCS explant surgery (SCSES)...

BACKGROUND/AIM: Definitive chemoradiotherapy (CRT) without planned surgery has been recently widely used as a therapeutic option for locally advanced esophageal cancer. Salvage esophagectomy can offer the chance of prolonged survival for patients who have locoregional failure after definitive CRT, but many clinicians oppose the use of surgery due to the associated excessive morbidity and mortality. The aim of this study was to identify patients who are good candidates for salvage surgery by investigating factors influencing long-term survival...

Toe-to-finger transplantation is intimately related to the development of microsurgical free tissue transplantation, which is one of the most important advances in the history of reconstructive surgery. It is also generally acknowledged that a mangled hand with massive tissue loss and amputation of multiple digits presents a challenge for plastic and reconstructive surgeons. In this retrospective study we reviewed 11 cases of primary one-stage post-traumatic reconstruction of complex fingerless hands using a combination of toe-to-finger and free tissue transplantation performed in Shanghai Jiao Tong University affiliated Sixth People's Hospital and Shanghai Jiao Tong University School of Medicine affiliated Ninth People's Hospital from January 2001 to November 2014...

To date, five cancer treatment modalities have been defined. The three traditional modalities of cancer treatment are surgery, radiotherapy, and conventional chemotherapy, and the two modern modalities include molecularly targeted therapy (the fourth modality) and immunotherapy (the fifth modality). The cardiotoxicity associated with conventional chemotherapy and radiotherapy is well known. Similar adverse cardiac events are resurging with the fourth modality. Aside from the conventional and newer targeted agents, even the most newly developed, immune-based therapeutic modalities of anticancer treatment (the fifth modality), e...
