BACKGROUND: Prior studies have shown that the posterior cruciate ligament (PCL) may be partially resected during cruciate retaining (CR) total knee arthroplasty (TKA) using highly experienced hands and standard surgical technique; therefore, proper surgical technique is aimed at preservation and balance of the PCL during CR TKA. The central objective of this study is to evaluate the effectiveness of a simple surgical technique to prevent PCL damage during performance of a CR TKA. METHODS: Sixty embalmed cadaver specimens were randomized into 2 groups, experimental and control...

Surgical management of extensive tumors in the mandibular region leads to massive disfigurement of the face. Also the prosthetic outcome of such patients rehabilitated with free soft tissue flaps is very poor. Reconstruction of extensive defects to overcome the disfigurement is a challenging procedure and can be achieved with free fibula flap. Free fibula graft provides sufficient length of bone for the reconstruction of the postsurgical defects. Excellent vascularity of fibula flap allows for easy uptake of the graft and osseointegration of the dental implants...

Surgical treatment of advanced facial tumours is often physically, functionally and emotionally debilitating. The resulting defects often give grounds for surgical reconstruction, prosthetic reconstruction or a combination of both. During the past two decades, huge advances have been achieved in the development of prostheses. This has led to improved rehabilitation of facial defects. In the clinic of the Netherlands Cancer Institute - Antoni van Leeuwenhoek, both adhesive- and implant-retained facial prostheses are used...

The neck is an aesthetic unit for which a rejuvenation request is sometimes very targeted or ore often encompassed in a global surgical project of face-lift. To obtain a long lasting outcome, the plastic surgeon has to make a full, detailed, and exhaustive analysis of the neck in order to choose the best indication within the multiple surgical tools. A full clinical examination is the key point, every aspects are outlined. The numerous surgical choices are described, illustrated, and sometimes revisited in the light of targeted anatomical studies...

Near-infrared fluorescence (NIRF) dyes have recently emerged as promising tools for non-invasive imaging of different types of cancers. Here, we explored the potential utility of a NIRF DZ-1 dye, with dual imaging and tumour targeting functions, in hepatocellular carcinoma (HCC). We showed the preferential uptake of DZ-1 by HCC cells in vitro and in derived subcutaneous/orthotopic tumour xenografts, accompanied by a minimal effect on normal cells. DZ-1 simplified tumour growth profiling as well, since we were able to correlate NIRF signals with tumour volume and/or tumour-emitting luminescence in mice...

BACKGROUND: Ballistic injuries with retained foreign bodies from air guns is a relatively common problem, particularly in children and adolescents. If not removed in a timely fashion, the foreign bodies can result in complications, including pain and infection. Diagnostic methods to identify the presence of the foreign body run the entire gamut of radiology, particularly radiography, ultrasound (US) and computed tomography (CT). Removal of the foreign bodies can be performed by primary care, emergency, surgical, and radiologic clinicians, with or without imaging guidance...

PURPOSE: Few studies have investigated the risk factors for implant removal after treatment for spinal surgical site infection (SSI). Therefore, there is no firmly established consensus for the management of implants. We aimed to investigate the incidence and risk factors for implant removal after SSI managed with instrumentation, and to examine potential strategies for avoiding implant removal. METHODS: Following a survey of seven spine centers, we retrospectively reviewed the records of 55 patients who developed SSI and were treated with reoperation, out of 3967 patients who had spinal instrumentation between 2003 and 2012...

BACKGROUND: Uterine-preserving prolapse surgery offers the chance to retain fertility; however, limited data is available for the safety of pregnancy following surgery and the effect of pregnancy on surgical outcome. Our operative technique involves mesh encircling the cervix and uterine arteries, which raises concerns that compromise of uterine blood flow during pregnancy may lead to foetal growth restriction. We also think this necessitates delivery by caesarean section. We report on six pregnancy outcomes following laparoscopic hysteropexy...

Nocardia species and Actinomyces species are 2 of the most commonly diagnosed filamentous bacteria in routine cytopathology practice. These genera share many overlapping cytomorphologic features, including their thin, beaded, branching, Gram-positive, GMS-positive filamentous structures that fragment at their peripheries into bacillary- and coccoid-appearing forms. Features that help distinguish between these 2 microorganisms include the width of their filamentous structures, the angles at which they branch, and their ability or lack thereof to retain a modified acid-fast stain...

PURPOSE: Following total knee arthroplasty (TKA), high tibial forces, large differences in tibial forces between the medial and lateral compartments, and anterior translation of the contact locations of the femoral component on the tibial component during passive flexion indicate abnormal knee function. Because the goal of kinematically aligned TKA is to restore native knee function without soft tissue release, the objectives were to determine how well kinematically aligned TKA limits high tibial forces, differences in tibial forces between compartments, and anterior translation of the contact locations of the femoral component on the tibial component during passive flexion...

Reduction mammaplasty is the volumetric reduction in the bulk of the breast. Techniques have evolved from primarily reducing the breast bulk to reducing with emphasis on functional and aesthetic outcome. The deeper understanding of the surgical anatomy of the breast has guided this development. While Paulus Aegina (sixth century AD), Dieffenbach (1848) and Gaillard-Thomas (1882) set the pace in glandular reduction; Pousson (1897) and Dehner (1908) focused on breast ptosis. It took quite some time before the enigma of the vascularization to the nipple areolar complex could be solved...

INTRODUCTION: Immediate implant-loading protocol has progressed because of various clinical advantages offered by this treatment approach. However, available studies on edentulous patients are still few compared to those in which delayed implant-loading protocol was applied. AIM: This prospective study was to evaluate the implant survival rate and the peri-implant tissue response in a group of patients who received two unsplinted immediately loaded dental implants in the mandibular anterior region to retain a complete overdenture using locator attachments...

BACKGROUND: Children with heart disease may require repeated X-Ray cardiac catheterization procedures, are more radiosensitive, and more likely to survive to experience oncologic risks of medical radiation. Cardiovascular magnetic resonance (CMR) is radiation-free and offers information about structure, function, and perfusion but not hemodynamics. We intend to perform complete radiation-free diagnostic right heart catheterization entirely using CMR fluoroscopy guidance in an unselected cohort of pediatric patients; we report the feasibility and safety...

REVIEW
Salvatore Risitano, Pier Francesco Indelli
A rectangular and symmetrical gap in flexion as well as in extension is mandatory to achieve good outcomes and good long-term results in total knee arthroplasty (TKA) using classical designs. Recently, as showed in several fluoroscopic studies, different modern designs (medial congruent or sagittally stable implants) have been demonstrated to better reproduce the more physiological medial pivoting (MP) biomechanics of the normal knee when compared to classical postero-stabilized (PS) and cruciate-retaining (CR) designs...
