Sacroiliac Joint Tuberculosis With Concomitant Iliopsoas Abscess Suggesting a Diagnostic and Therapeutic Challenge: A Case Report.

Sacroiliac joint (SIJ) tuberculosis (TB) is an infrequent clinical entity, especially in developed countries. The symptoms are usually non-specific, and therefore it may mimic a variety of degenerative and non-degenerative diseases, hampering the diagnosis. An interesting case of SIJ infection with psoas abscess in a 77-year-old male is presented in the current article.

Frequencies or Absolute Numbers? Cluster Analysis of Frequencies and Absolute Numbers of B-Cell Subsets in Dialysis Patients Who Are Candidates for Kidney Transplantation Reveals Different Profiles.

Detailed characterization of B cells in dialysis patients who are candidates for kidney transplant is still lacking, with little information on how dialysis duration and modality impact B cell subsets. Cluster analysis of flow cytometry determined the frequencies and absolute numbers of B-cell subsets and divided the cohort of 78 candidates into two distinct clusters, one with shorter and one with longer dialysis duration. The immune profiles of the clusters differed depending on whether frequencies or absolute counts were considered.

Hinchey III Diverticulitis in a 31-Year-Old Patient With Williams Syndrome: A Case Report.

Williams syndrome was first reported by Williams and Beuren in 1961-1962. It is a genetic disorder that is caused by a sporadic microdeletion of chromosome 7, which includes the elastin gene. The development of gastrointestinal pathology, such as diverticular disease, is associated with the deletion of this specific gene.

Two synchronous primary mesenteric neuroendocrine tumors in a patient: a case report.

Primary mesenteric neuroendocrine tumors represent a rare clinical entity, challenging to manage, while a combination of imaging is demanded in order to differentiate it from metastatic disease, and set the diagnosis. If the tumor is resectable, surgery is the fundament of the therapeutic approach. The appearance of a second primary mesenteric tumor suggests an unacquainted scenario.

Exploring Perturbations in Peripheral B Cell Memory Subpopulations Early after Kidney Transplantation Using Unsupervised Machine Learning.

Background: B cells have a significant role in transplantation. We examined the distribution of memory subpopulations (MBCs) and naïve B cell (NBCs) phenotypes in patients soon after kidney transplantation. Unsupervised machine learning cluster analysis is used to determine the association between the cellular phenotypes and renal function.

The Dynamic and Crucial Role of the Arginine Methylproteome in Myoblast Cell Differentiation.

Protein arginine methylation is an extensive and functionally significant post-translational modification. However, little is known about its role in differentiation at the systems level. Using stable isotope labeling by amino acids in cell culture (SILAC) proteomics of whole proteome analysis in proliferating or five-day differentiated mouse C2C12 myoblasts, followed by high-resolution mass spectrometry, biochemical assays, and specific immunoprecipitation of mono- or dimethylated arginine peptides, we identified several protein families that were differentially methylated on arginine.

Gastric Duplication in an Adult Female: A Challenging Diagnosis.

Gastrointestinal duplications can be found in all parts of the gastrointestinal tract. Duplications of the stomach comprise 2-8% of all duplications and are mostly diagnosed during the first year of life. We present a case of a gastric duplication cyst in a 29-year-old female, presenting with epigastric pain and vomiting.

Long-Term (≥25 Years) Kidney Allograft Survivors: Retrospective Analysis at a Single Center.

Introduction: Despite great improvements in the short-term patient and kidney graft survival, the long-term morbidity and mortality in kidney transplant recipients still remains a significant problem. The aim of the study was to evaluate the impact of both donor and transplant recipient factors, as well as renal function indices on the very long-term (>25 years) kidney allograft survival.

Material And Methods: Retrospective analysis was performed on the data of 41 kidney transplant recipients (KTR), group A: follow-up = 25 years, 20 KTR, 10 male, mean age (mean [M] ± standard deviation [SD]): 34.

Hepatic Artery Anatomic Variations and Reconstruction in Liver Grafts Procured in Greece: The Effect on Hepatic Artery Thrombosis.

Aims: Variations of the anatomy of donor hepatic arteries increase the number of arterial anastomoses during liver transplantation and, possibly, the incidence of hepatic artery thrombosis (HAT). In this study, we describe the arterial anatomic variations in liver grafts procured and transplanted by a single center in Greece, the techniques of arterial anastomosis, and their effect on the incidence of early HAT.

Materials And Methods: From January 2013 to December 2017, the arterial anatomy of 116 grafts procured for liver transplantation were recorded, as well as the technique of arterial anastomosis and the incidence of early hepatic artery thrombosis (HAT <30 days).

Association of Double-J Stenting in Renal Transplant Patients With Urinary Tract Colonization and Infections in a Multidrug-resistant Microbe Endemic Nosocomial Environment.

Purpose: We investigated the association of ureteral stenting after kidney transplantation with the development of urinary tract infections (UTIs) and/or urinary tract colonization, in a hospital environment considered endemic for multidrug resistant (MDR) Gram-negative Enterobacteriaceae.

Methods: Seventy-five recipients of deceased donor grafts were divided in groups A and B. Group A (with subgroups A1 and A2) included 45 transplanted patients without urinary stenting, and group B 30 patients with stenting.

Kidney Transplantation in Old Recipients From Old Donors: A Single-Center Experience.

Purpose: The program Old for Old or European Senior Program (ESP), allocates donors aged ≥65 years to recipients of ≥65, within a narrow geographic area in order to minimize cold ischemia time, decrease the waiting time for elderly patients listed for kidney transplantation and expand the transplant resource in this group. The ESP is not officially applied in Greece. In our center, the Old for Old criteria have been used since 2003 for elderly patients who are candidates for kidney transplantation.
