INTRODUCTION: Posterior reversible leukoencephalopathy syndrome (PRES) was first described by Hinchey in 1996. The syndrome is characterized by altered level of consciousness, headache, visual changes, and seizures associated with a vasogenic edema of the white matter that occurs predominantly in the occipital and parietal lobes. Imaging tests such as computed tomography (CT) and especially magnetic resonance imaging (MRI) support the diagnosis. CASE REPORT: We report a case of a 48-year-old female patient who underwent a deceased donor kidney transplant and received tacrolimus as a part of the immunosuppressive regimen...

INTRODUCTION: Brachial artery aneurysms are relatively uncommon and generally due to infectious, post-traumatic or iatrogenic etiology. They seem to affect 4.5% of arteriovenous fistula. The usual manifestation is an accidental finding of a pulsatile, painless, and asymptomatic mass. Complications include sac thrombosis, thromboembolic ischaemic events, and disruption with profuse bleeding. METHODS: The aim of this study is to present a case of true brachial artery aneurysm in end-stage renal disease patient after arteriovenous fistula creation...

Background: Islet transplantation (Tx) represents the most promising therapy to restore normoglycemia in type 1 diabetes (T1D) patients to date. As significant islet loss has been observed after the procedure, there is an urgent need for developing strategies for monitoring transplanted islet grafts. In this report we describe for the first time the application of magnetic particle imaging (MPI) for monitoring transplanted islets in the liver and under the kidney capsule in experimental animals...

Post-transplantation lymphoproliferative disorder (PTLD) is a heterogeneous group of conditions that complicate organ transplantation and are due to immunosuppression. Central nervous system (CNS)-PTLD is rare but its incidence is increasing. It often occurs late and is associated with kidney transplantation and Epstein-Barr virus (EBV) infection. Outcomes are poor. We present the case of a 77-year-old white male who received a cadaveric kidney transplant in 2003. Maintenance immunosuppression consisted of mycofenolate mofetil (MMF), cyclosporine, and prednisolone...

BACKGROUND: Post-transplant lymphoproliferative disorder (PTLD) is a rare condition occurring after organ transplantation. PTLD comprises four subtypes, of which Hodgkin lymphoma (HL)-type and HL-like type (currently included in polymorphic type) account for only about 1%-3% of cases. Primary central nervous system PTLD is also rare, and most cases are Epstein-Barr virus-positive, B-cell PTLD, while no case of HL-like PTLD has yet been documented. CASE DESCRIPTION: We present a 43-year-old woman who underwent kidney transplantation for IgA nephropathy 14 years previously, and who presented to our Emergency Department with a chief complaint of seizure...

Renal transplantation is the therapy of choice for patients with end-stage renal diseases. Improvement of immunosuppressive therapy has significantly increased the half-life of renal allografts over the past decade. Nevertheless, complications can still arise. An early detection of allograft dysfunction is mandatory for a good outcome. New advances in magnetic resonance imaging (MRI) have enabled the noninvasive assessment of different functional renal parameters in addition to anatomic imaging. Most of these techniques were widely tested on renal allografts in past decades and a lot of clinical data are available...

Hepatic and renal energy status prior to transplantation correlates with graft survival. However, effects of brain death (BD) on organ-specific energy status are largely unknown. We studied metabolism, perfusion, oxygen consumption, and mitochondrial function in the liver and kidneys following BD. BD was induced in mechanically-ventilated rats, inflating an epidurally-placed Fogarty-catheter, with sham-operated rats as controls. A 9.4T-preclinical MRI system measured hourly oxygen availability (BOLD-related R2*) and perfusion (T1-weighted)...

Diabetic muscle infarction (DMI) refers to spontaneous ischemic necrosis of skeletal muscle among people with diabetes mellitus, unrelated to arterial occlusion. People with DMI may have coexisting end-stage renal disease (ESRD) but little is known about its epidemiology and clinical outcomes in this setting. This scoping review seeks to investigate the characteristics, clinical features, diagnostic evaluation, management and outcomes of DMI among people with ESRD. Electronic database (PubMed/MEDLINE, CINAHL, SCOPUS and EMBASE) searches were conducted for ("diabetic muscle infarction" or "diabetic myonecrosis") and ("chronic kidney disease" or "renal impairment" or "dialysis" or "renal replacement therapy" or "kidney transplant") from January 1980 to June 2017...

BACKGROUND: After orthotopic liver transplantation (OLT) for hepatocellular carcinoma (HCC), recurrent HCC mostly develops within 2 years. All cases of de novo HCC described so far occurred later than 2 years after OLT. Prevention of post-transplantation HCC has usually been tried to achieve by curing or controlling recurrent liver disease. This has been rationale for treatment with interferon (IFN)/ribavirin of HCV-recurrence in patients after OLT, transplanted for advanced HCV-induced liver disease and/or HCC...

Vascular complications are a significant source of morbidity and mortality among renal transplant recipients. Imaging using ultrasound, CT, and MRI plays a key role in diagnosing such complications. This review focuses on the major vascular complications of renal grafts, which include transplant renal arterial and venous stenoses, arterial and venous thromboses, arteriovenous fistulas, and pseudoaneurysms. Etiology, diagnostic modalities useful for diagnosis, and imaging appearance will be presented.

BACKGROUND: The neuroanatomic basis for cognitive impairment in chronic kidney disease (CKD) is incompletely characterized. We performed advanced quantitative structural magnetic resonance imaging (MRI) to determine whether CKD affects brain structure and whether poorer neurocognitive performance in CKD is associated with structural brain differences. STUDY DESIGN: Cross-sectional. SETTING & PARTICIPANTS: 85 individuals with CKD stages 2 to 5 and 63 healthy controls, aged 8 to 25 years PREDICTORS: CKD versus control, estimated glomerular filtration rate (eGFR), and kidney transplant status were analyzed as predictors of MRI findings...

RATIONALE: Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening disease entity primarily described in children, but not less relevant in adults. It is characterized by a misdirected activation of the immune system, resulting in an uncontrolled cytokine release from macrophages and cytotoxic T-cells (CTLs). Primary HLH relies on a genetic predisposition, whereas secondary HLH develops in the context of infections, malignancies or autoimmune diseases. However, the awareness and therapeutic knowledge for HLH in adulthood is limited...

Background Multiple myeloma is a haematological blood cancer of the bone marrow and is classified by the World Health Organisation (WHO) as a plasma cell neoplasm. In multiple myeloma, normal plasma cells transform into malignant myeloma cells and produce large quantities of an abnormal immunoglobulin called monoclonal protein or M protein. This ultimately causes multiple myeloma symptoms such as bone damage or kidney problems. The annual worldwide incidence of multiple myeloma is estimated to be 6 - 7/100,000 and accounts for 1% of all cancer...

Wilson disease (WD) is an autosomal genetic disorder characterized by excessive copper deposition initially in liver (hepatic variant) followed by brain (neuropsychiatric variant) and other organs such as cornea and kidney due to defect in biliary copper excretion. Predominant presentations of neuropsychiatric variant are extrapyramidal motor dysfunctions such as dystonias, Parkinsonism, choreoathetosis, tremor, and ataxias. Nonmotor symptoms (NMS) can appear before clinical disease expression and during ongoing disease process...

A 29-year-old man complained of a 2-day history of frontal headache and new-onset fever but no other symptoms. Two months prior to admission, he underwent his third kidney transplantation. Clinical and laboratory examinations were unremarkable. Brain MRI showed a meningeal irritation consistent with viral meningitis. A diagnosis of cryptococcal meningitis and fungaemia was made after detection of a remarkably high and visible load of Cryptococcus neoformans in the cerebrospinal fluid.
