During the past decade, polyoma virus (PV) infection has emerged as an important cause of graft dysfunction and failure in kidney transplant recipients. Establishing the correct diagnosis can be difficult, however, because the histologic appearance of PV infection can resemble acute cellular rejection. We report a kidney-pancreas transplant recipient with PV infection, in whom both vascular and cellular rejection were dominant histologic features in a renal biopsy specimen. The patient was successfully managed by tapering immunosuppressive therapy, and continues to have good graft function 3 years after diagnosis of PV infection. This case highlights the spectrum of inflammatory changes associated with PV infection, and the need for caution when such changes are attributed to rejection.

Background: Lung transplantation is a viable lifesaving option for patients with diffuse pulmonary arteriovenous malformations (AVMs). We present a case of diffuse pulmonary AVMs associated with juvenile polyposis and hereditary hemorrhagic telangiectasia (JP-HHT) that was successfully managed by lung transplantation.
Case Presentation: A 19-year-old woman developed severe hypoxemia due to pulmonary AVMs diagnosed at 4 years of age.

Introduction Cytomegalovirus (CMV) is often associated with mortality and significant morbidity following renal transplantation leading to graft rejection or dysfunction. Primary CMV infection refers to the first detection of the virus in a person who has no prior evidence of CMV exposure before transplantation. CMV has a unique property called latency.

Conditions such as congenital abnormalities, cancer, infections, and trauma can severely impact the integrity of the auricular cartilage, resulting in the need for a replacement structure. Current implants, carved from the patient's rib, involve multiple surgeries and carry risks of adverse events such as contamination, rejection, and reabsorption. Tissue engineering aims to develop lifelong auricular bioimplants using different methods, different cell types, growth factors and maintenance media formulations, and scaffolding materials compatible with the host.

While the Banff classification dichotomizes kidney allograft rejection based on the localization of the cells in the different compartments of the cortical kidney tissue [schematically interstitium for T cell mediated rejection (TCMR) and glomerular and peritubular capillaries for antibody-mediated rejection (AMR)], there is a growing evidences that subtyping the immune cells can help refine prognosis prediction and treatment tailoring, based on a better understanding of the pathophysiology of kidney allograft rejection. In the last few years, multiplex IF techniques and automatic counting systems as well as transcriptomics studies (bulk, single-cell and spatial techniques) have provided invaluable clues to further decipher the complex puzzle of rejection. In this review, we aim to better describe the inflammatory infiltrates that occur during the course of kidney transplant rejection (active AMR, chronic active AMR and acute and chronic active TCMR).

Background: Current treatments for penile erectile structures reconstruction are limited and remain a great challenge in clinical practice. Tissue engineering techniques using different seed cells and scaffolds to construct a neo-tissue open promising avenues for penile erectile structures repair and replacement and show great promise in the restoration of: structure, mechanical property, and function which matches the original tissue.
Methods: A comprehensive literature review was conducted by accessing the NCBI PubMed, Cochrane, and Google Scholar databases from January 1, 1990, to January, 1, 2022 using the search terms "Tissue engineering, Corpus cavernosum (CC), Tunica albuginea (TA), Acellular Matrix, Penile Reconstruction".
