REVIEW
Tin Moe Wai, Eun Young Kim
Pancreaticobiliary complications following various surgical procedures, including liver transplantation, are not uncommon and are important causes of morbidity and mortality. Therapeutic endoscopy plays a substantial role in these patients and can help to avoid the need for reoperation. However, the endoscopic approach in patients with surgically altered gastrointestinal (GI) anatomy is technically challenging because of the difficulty in entering the enteral limb to reach the target orifice to manage pancreaticobiliary complications...

The terminologies of "body size", "body mass index (BMI)", "body weight", "large BMI" and "obesity" are controversial for defining the effects of "adiposity" or "fat excess" on the outcomes of dialysis and transplant patients. However, probably these terminologies will be continued to be used in the future as well, because of being older and simpler terminologies. In the general population obesity is a powerful risk factor for cardiovascular morbidity and mortality, while, it conferred a survival advantage to dialysis patients...

INTRODUCTION: Pediatric hand transplantation (PHT), an investigational therapy, was recently performed in the United States. RESEARCH QUESTIONS: Perspectives of hand therapists about PHT patient selection (inclusion and exclusion criteria), team configuration, patient assent, and patient compliance were explored. DESIGN: Quantitative survey. We used a research ethics committee-approved 18-question e-link anonymous questionnaire to survey members of the American Society of Hand Therapists and the Australian (AU) Hand Therapy Association for their perspectives on PHT...

Total body irradiation (TBI) has been thought to promote donor cell engraftment in allogeneic hematopoietic cell transplantation (HCT) from alternative donors. However, recent progress in HCT strategies may affect the clinical significance of TBI on neutrophil engraftment. With the use of a Japanese transplant registry database, we analyzed 3933 adult recipients (>15 y.o.) who underwent HCT between 2006 and 2013 from an 8/8 HLA-matched unrelated bone marrow donor (MUD, n=1367), an HLA-mismatched unrelated bone marrow donor (MMUD, n=1102), or unrelated cord blood (CBT, n=1464)...

Transplantation in reconstructive surgery has been performed for more than 20 years, although the official beginning of these procedures is considered the first successful transplantation of the hand in 1998. The original name "Composite Tissue Transplantation" has been used less frequently; more common is the term "Vascularized Composite Allotransplant", which better describes the basis of the procedure. There have been so far approximately 180 transplantations performed, the exact number is difficult to find...

The vast majority of the human adult population is infected with Epstein-Barr virus (EBV), and the majority of the EBV-infected individuals tolerates the infection well, without any further symptoms after primary infection. In cases of individuals which undergo primary infection in the form of an infectious mononucleosis, or which have undergone primary infection in their past, it is sometimes important to appraise symptomatic disease or differentiate infectious mononucleosis from other conditions. In these cases, serological methods, i...

BACKGROUND: The development of safe and reliable protocols for the transplantation of the face and hands may be accomplished with animal modeling of transplantation of vascularized composite allografts (VCA). Previously, we demonstrated that tolerance to a VCA could be achieved after canine recipients were simultaneously given marrow from a dog leukocyte antigen-identical donor. In the present study, we extend those findings across a dog leukocyte antigen mismatched barrier. METHODS: Eight recipient dogs received total body irradiation (4...

We explored the clinical course of acute high-grade gastrointestinal graft-versus-host disease in children in a single center. This was a retrospective analysis of 28 pediatric patients who presented with a clinical diagnosis of stage III and IV acute graft-versus-host disease (aGVHD) of the gastrointestinal system (GIS). Generally, skin involvement was the initial manifestation of aGVHD that began in the first 3 weeks of hematopoietic stem cell transplantation (HSCT); on the other hand, GIS involvement predominated after the second week of HSCT...

REVIEW

Urolithiasis in the context of renal transplant is a quite rare event that requires keeping a higher index of suspicion and vigilance. Donors with incidentally discovered asymptomatic renal stones "donor gifted lithiasis" are potentially considered for donation should they are not recurrent stone formers and in the absence of active biochemical disorders. Stone clearance from the donors can be done before donation using shock wave lithotripsy and/or flexible ureteroscopy. Ex vivo ureteroscopy at time of transplant is equally feasible and safe...

BACKGROUND: Solid organ transplantation (SOT) frequently is complicated by cytomegalovirus (CMV) infections. Cidofovir (CDV) is active against CMV, including many ganciclovir (GCV)-resistant mutants, but often is considered to be too nephrotoxic for use after organ transplantation. PATIENTS AND METHODS: Seven males and two females (median age 50.1 years), including two kidney/pancreas, four lung, one small bowel, and two hand recipients, received CDV for refractory CMV disease...

BACKGROUND: The emerging role of stem cell technology and transplantation has helped scientists to study their potential role in neural repair and regeneration. The fate of stem cells is determined by their niche, consisting of surrounding cells and the secreted trophic growth factors. This interim report evaluates the safety, feasibility and efficacy (if any) of bone marrow-derived mononuclear stem cells (BM-MNC) in chronic ischemic stroke by studying the release of serum vascular endothelial growth factor (VEGF) and brain-derived neurotrophic growth factor (BDNF)...

BACKGROUND: The development of effective immunosuppressive regimens has resulted in many cases of successful hand transplantation. Visual skin inspection and histological evaluation are used to assess the rejection of hand transplants, but these methods are largely subjective. In this study, we aimed to determine the potential of microRNAs (miRNAs) as biomarkers for acute rejection in vascularized composite allotransplants. METHODS: In allograft group, 7 male Brown-Norway rats (RT1(n)) were used as donors and 13 male Lewis rats (RT1(l)) were used as recipients...

AIMS AND OBJECTIVES: To explore the experiences of spouses of heart transplant recipients and to consider how an understanding of these experiences may inform nursing practice. BACKGROUND: There is a lack of knowledge about the experiences of spouses of heart transplant recipients during the pre-transplant wait. Evidence suggests that spousal support improves post-transplant outcomes of heart transplant recipients, therefore it is important to understand how nurses can improve spouses' psychological well-being during the pre-transplant wait...

Refractory coeliac disease (RCD) is a recognised complication, albeit very rare, of coeliac disease (CD). This condition is described when individuals with CD continue to experience enteropathy and subsequent or ongoing malabsorption despite strict adherence to a diet devoid of gluten for at least 12 months and when all other causes mimicking this condition are excluded. Depending on the T-cell morphology and T-cell receptor (TCR) clonality at the β/γ loci, RCD can be subdivided into type 1 (normal intra-epithelial lymphocyte morphology, polyclonal TCR population) and type 2 (aberrant IELs with clonal TCR)...

Complement component 3 (C3) presents both slow (C3S) and fast (C3F) variants, which can be locally-produced and activated by immune system cells. We studied C3 recipient variants in 483 liver transplant patients by RT-PCR-HRM to determine their effect on graft outcome during the first year post-transplantation. Allograft survival was significantly decreased in C3FF recipients (C3SS 95% vs. C3FS 91% vs. C3FF 83%; p=0.01) or C3F allele carriers (C3F-absence 95% vs. C3F-presence 90%, p=0.02). C3FF genotype or presence of C3F allele independently increased risk for allograft loss (OR: 2...

: Different diseases lead, during their advanced stages, to chronic or acute liver failure, whose unique treatment consists in organ transplantation. The success of intervention is limited by host immune response and graft rejection. Immunosuppressant drugs permitted improving organ transplantation but they cannot completely solve the problem and their management is delicate, especially during the early stages of treatment. Thus, new tools to set an efficient modulation of immune response are required...

Lung surfactant is a complex mixture of lipids and proteins lining the alveolar epithelium. At the air-liquid interface, surfactant lowers surface tension, avoiding alveolar collapse and reducing the work of breathing. The essential role of lung surfactant in breathing and therefore in life, is highlighted by surfactant deficiency in premature neonates, which causes neonatal respiratory distress syndrome and results in early death after birth. In addition, defects in surfactant metabolism alter lung homeostasis and lead to disease...
