Positivity rate of interferon-γ release assays for estimating the prevalence of latent tuberculosis infection in renal transplant recipients in Japan.

Renal transplant recipients are at increased risk of reactivating latent tuberculosis infection (LTBI) and developing active tuberculosis. QuantiFERON-TB Gold Plus (QFT-Plus) has two TB-specific antigens tubes (TB1 and TB2). TB1 elicits CD4 T-cell response, and TB2 elicits both CD4 and CD8 T-cells responses, with expected increased sensitivity.

Renal Autotransplantation and Extracorporeal Nephron-Sparing Surgery for De Novo Renal Cell Carcinoma in a Kidney Allograft.

De novo renal cell carcinoma (RCC) rarely occurs in kidney allografts; however, the risk of RCC in these patients is 100-fold that of the general healthy population. Although total nephrectomy has been the standard treatment for kidney allograft RCC, several authors have reported that early-stage RCC in kidney allografts was successfully treated with nephron-sparing surgery. We herein describe a new procedure involving renal autotransplantation and extracorporeal nephron-sparing surgery, which was performed to treat de novo RCC near the hilum of a transplanted kidney.

Comparison of interferon-γ release assays, QuantiFERON TB-GIT and T-Spot.TB, in renal transplantation.

Renal transplant recipients are at increased risk of reactivating latent tuberculosis infection (LTBI) and progressing to active tuberculosis (TB). This study was conducted in National hospital for tuberculosis and renal transplantation (RT) in Japan. The purpose is to compare two interferon-γ release assays (IGRAs), QuantiFERON-TB Gold in Tube (QFT) and T-SPOT.

Focal segmental glomerular sclerosis recurrence with massive proteinuria and anuria immediately after kidney transplantation.

Here, we report a case of focal segmental glomerular sclerosis (FSGS) recurrence immediately (47 minutes) after transplantation. A 1-hour biopsy specimen showed large periodic acid-Schiff-positive granules within the cells of the swollen proximal tubule, while electron microscopy revealed podocyte swelling and partial foot process effacement. These findings were worse on day 2 biopsy.

A Review of Autologous Islet Transplantation.

Autologous islet transplantation after total or semitotal pancreatectomy aims to preserve insulin secretory function and prevent the onset of diabetes. The major indication for pancreatectomy is chronic pancreatitis with severe abdominal pain, a benign pancreatic tumor, and trauma. The metabolic outcome of autologous islet transplantation is better than that of allogeneic transplantation and depends on the number of transplanted islets.

Results of islet isolation and their relationship to the clinical outcome of kidney transplantation in cases where both grafts are harvested from the same non-heart-beating donor.

Grafts from non-heart-beating donors (NHBDs) are used because of the limited availability of heart-beating brain-dead donors. These grafts sustain ischemic damage, and the severity of this damage varies among different areas of an organ. This study determined whether the results of islet isolation were correlated with the clinical outcomes of kidney transplantations in cases where both grafts were harvested from the same NHBD.

Depth elemental imaging of forensic samples by confocal micro-XRF method.

Micro-XRF is a significant tool for the analysis of small regions. A micro-X-ray beam can be created in the laboratory by various focusing X-ray optics. Previously, nondestructive 3D-XRF analysis had not been easy because of the high penetration of fluorescent X-rays emitted into the sample.

Laparoscopic-assisted distal pancreatectomy and nephrectomy from a live donor.

Background: The simultaneous transplantation of pancreas and kidney from live donors is performed in select countries. One of the reasons for this reduced applicability is the invasiveness of the donor operation. We propose the method of laparoscopic-assisted operation to be performed on live donors with minimal invasion.

[A case of complete response to combination therapy of S-1 and CDDP for Stage IV gastric cancer with Virchow's lymph node and para-aorta lymph node metastasis].

The patient was a 53-year-old male with Stage IV gastric cancer with Virchow's lymph node and para-aorta lymph node metastasis. The chemotherapy regimen was given S-1 orally at 80 mg/m(2) day on day 1 to 21 and CDDP intravenously at 60 mg/m(2) day on day 8, repeated for 35 days. After two courses and a reduced regimen with S-1 64 mg/m(2) day plus CDDP 35 mg/m(2) day, the tumor lesion became CR and the serum CEA 575 ng/mL level before therapy decreased to the normal level.
