Pterygium is a degenerative condition characterized by fibrovascular outgrowth of conjunctiva over the cornea. Many theories exist that try to explain its pathogenesis. The current belief is that this disease is multifactorial with ultraviolet radiation being the most important trigger. Attention is also paid to such factors as tear film changes, cytokines and growth factors disbalance, immunologic disturbances, genetic mutations, and viral infections. Modern classifications consider the rate of fibrovascular growth, its progressive potential, and histological features...

Through concerted endeavours in the fields of surgery, medicine, and biomedical engineering, patronized by government and industry, ventricular assist devices have become an established surgical treatment to support the failing heart, which could easily and simply surpass the frequency of heart transplantation. Be it as it may, complications and adverse events have unfolded, and these facilitated the way to newer biomedically-engineered pump designs in search of the perfect support for a failing heart. Areas covered: This review focuses on the evolution of the continous-flow ventricular assist device as an accepted mode of treatment in advanced heart failure, as a bridge to myocardial recovery, as a bridge to heart transplantation and as a permanent therapy, with its attendant complications and long-term outcome...

Background: Autologous fat grafting is commonly used for soft-tissue augmentation and reconstruction. However, this technique is limited by a high rate of graft absorption. Thus, approaches to improve fat graft survival that promote neovascularization are of great interest. Nanofat has several beneficial features that may render it more suitable for clinical applications than other stem-cell based approaches. Objectives: We aimed to determine whether nanofat could enhance new vessel formation and improve the long-term retention of fat grafts...

The assessment of Quality of Life (QoL) after transplantation represents an ancillary tool to evaluate the efficacy of solid organ transplantation, in addition to graft and patient survival rates and complication. The global assessment of QoL after transplantation usually confirms the improvement when compared to pre-transplant setting. However, whereas significant improvement in physical activity has been widely reported, several studies have demonstrated that social domain and cognitive function do not reach the level of general population after surgery...

BACKGROUND: Death with graft function (DWGF) is an important cause of long-term loss of grafts and patients. In this study, we investigated clinical characteristics and causes of DWGF in kidney transplant recipients. METHODS: We recruited kidney allograft recipients who underwent surgery during 1973-2016 at Seoul National University Hospital in Korea (n = 2137). We divided recipients into four groups: alive with graft function (AWGF), alive with graft loss (AWGL), DWGF, and death with graft loss (DWGL)...

Introduction: Mucopolysaccharidosis Type II (MPS II; Hunter syndrome) is an X- linked lysosomal storage disorder caused by a deficiency of iduronate-2-sulfatase (IDS). IDS deficiency leads to primary accumulation of dermatan sulfate (DS) and heparan sulfate (HS). MPS II is both multi-systemic and progressive. Phenotypes are classified as either attenuated or severe (based on absence or presence of central nervous system impairment, respectively). Areas covered: Current treatments available are intravenous enzyme replacement therapy (ERT), hematopoietic stem cell transplantation (HSCT), anti-inflammatory treatment, and palliative care with symptomatic surgeries...

BACKGROUND: Maintaining anonymity is a requirement in the Netherlands and Sweden for kidney donation from live donors in the context of nondirected (or unspecified) and paired exchange (or specified indirect) donation. Despite this policy, some donors and recipients express the desire to know one another. Little empirical evidence informs the debate on anonymity. This study explored the experiences, preferences, and attitudes of donors and recipients toward anonymity. STUDY DESIGN: Retrospective observational multicenter study using both qualitative and quantitative methods...

OBJECTIVE: Liver transplantation (LT) is a major surgery associated with intraoperative massive fluid shift, which is usually replaced by crystalloid, 5% albumin (colloid) and blood products. We studied 15 patients from 477 consecutive recipients of adult living donor liver transplantation. Each patient received crystalloid only during LT. Whether LT provides any clinical benefit is not clear and must be determined. METHODS AND PATIENTS: The anesthesia records of 477 adult LDLT were reviewed retrospectively...

Background The gold standard therapy for full-thickness macular holes (FTMH) is vitrectomy (PPV) with peeling of the internal limiting membrane (ILM), gas tamponade of the vitreous cavity and postoperative face-down positioning. Nevertheless, eyes with large macular holes (> 400 µm) and surgical failures remain difficult to manage. Recently, ILM transplantation (ILM-TX) techniques were developed with acceptable results, advocating different mechanisms of hole closure: in such a setting, the ILM could serve as a scaffold for neuronal tissue in the pedicle ILM flap technique or the ILM could induce a contraction of the FTMH rims through shrinking of a folded ILM plug...

Among various models for spinal cord injury in rats, the contusion model is the most often used because it is the most common type of human spinal cord injury. The complete transection model, although not as clinically relevant as the contusion model, is the most rigorous method to evaluate axon regeneration. In the contusion model, it is difficult to distinguish regenerated from sprouted or spared axons due to the presence of remaining tissue post injury. In the complete transection model, a bridging method is necessary to fill the gap and create continuity from the rostral to the caudal stumps in order to evaluate the effectiveness of the treatments...

Liver transplantation is the best solution for end stage liver disease, and has been widely accepted and rapidly developed in the past decades. Along with the improved outcomes of liver transplantation, living-related donor transplantation has been conducted to overcome the shortage of the deceased donor. The most important aspects of the living-related liver transplantation are donor safety and fast recovery after graft procurement. Meanwhile, the rapid progress of minimally invasive surgery (MIS) in general surgery has generated heated debate regarding the appropriateness of MIS in living-related donor graft hepatectomy...

BACKGROUND The incidence of incisional hernia following renal transplantation is 1.1% to 3.8%. The risk factors are immunosuppressive medications, impaired tissue quality, neuromuscular trauma due to the operation, and denervation. The incidence has been decreasing based on the shift from hockey-stick incision method to inguinal oblique incision method. The aim of this study was to minimize the development of incisional hernias due to renal transplantation. MATERIAL AND METHODS Twenty-four patients who underwent renal transplantation in 2015-2017 were retrospectively examined...

REVIEW
Ashraf Fayad, Sasha K Shillcutt
PURPOSE: The use of transesophageal echocardiography (TEE) has evolved to include patients undergoing high-risk non-cardiac procedures and patients with significant cardiac disease undergoing non-cardiac surgery. Implementation of basic TEE education in training programs has increased across a broad spectrum of procedures in the perioperative arena. This paper describes the use of perioperative TEE in non-cardiac surgery and provides an overview of the basic TEE examination. PRINCIPAL FINDINGS: Perioperative TEE is used to monitor hemodynamic parameters in non-cardiac procedures where there is a high risk of hemodynamic instability...

PURPOSE: One factor that can contribute to severe bone loss after transplantation is the direct action of immunosuppressants on bone cells. The aim of this work was to study the effects of cyclosporine (CsA), tacrolimus (FK-506), and rapamycin (RAPA) on the release of three local factors directly implicated in bone-remodeling regulation and apoptosis of human osteoblasts: interleukin (IL)-6, osteoprotegerin, and receptor activator of nuclear factor κβ (RANKL). BASIC PROCEDURES: Human osteoblasts were obtained from five different patients who underwent orthopedic surgery...
