BACKGROUND: Kidney transplantation (KT) is the treatment option for patients with end stage renal disease (ESRD) to prolong survival and improve quality of life. Although the use of potent immunosuppressive agents increases graft survival in kidney transplantation recipients (KTRs), it may lead to the development of malignancy, including transitional cell carcinoma (TCC). TCC developing in the pelvis of graft kidney is very rare in KTRs. CASE PRESENTATION: A 40-year-old male visited hospital with complaints of nausea, vomiting and gross hematuria...

BACKGROUND: Computed tomography (CT)-guided percutaneous lung fine needle aspiration (FNA) is a convenient method to obtain samples from pulmonary lesions. FNA has a lower rate of complications than the use of a core needle biopsy, but is more difficult for the diagnosis of cytological samples. We use cell block (CB) and immunocytochemistry (ICC) to improve the accuracy of cytological diagnoses based on CT-guided percutaneous lung FNA. METHODS: We collected 526 cytological samples obtained using CT-guided percutaneous lung FNA at Shanghai Pulmonary Hospital from May 2015 to October 2015...

OBJECTIVE: To develop a new score (CATH-score) for predicting intra-procedural risk in patients undergoing CT-guided percutaneous needle pulmonary biopsy. PATIENTS AND METHODS: 100 CT-guided lung biopsies performed with a 18 Gauge (G) needle (Pilot Group) were reviewed to analyse patient-, lesion- and procedure-related variables to identify risk factors for procedural complications (pneumothorax and parenchymal bleeding) and diagnosis failure. A scoring system for predicting complications and choosing the right needle (16 G, 18 G, 21 G) was developed using risk factors weighting and prospectively applied to 153 consecutive biopsies (CATH-score Group); complications and diagnostic rates obtained were compared with a group of patients (Control Group) that underwent lung biopsy; in this group of patients the choice of the calliper of the needle was based on the operator experience...

REVIEW
Ahmed Mohyeldin, J Bradley Elder
The resolution and real-time navigation of intraoperative MRI (iMRI) has been leveraged in neurosurgery. We review frameless stereotactic biopsy platforms and focus on emerging technology integrating intraoperative MRI with frameless stereotaxy. Brain biopsy with iMRI allows for an accurate tissue sample with the ability to correct cannula trajectory during surgery, eliminating misdiagnosis secondary to faulty targeting. This technology allows for a percutaneous approach avoiding large incisions, obviates the need for frozen tissue evaluation, has the potential to reduce unnecessary specimen harvesting and operating room time, and optimizes safety of targeting deep brain lesions...

Dermatomyositis (DM) is a rare autoimmune condition which predominantly affects females in the fifth and sixth decades of life. DM presents acutely or progressively as painless proximal skeletal muscle weakness and can be associated with a heliotropic rash around the eyes, and Gottron's papules on extensor surfaces of the hands. While the pathophysiology of DM is still unclear, abnormal T- and B-cell immune activity has been reported. DM has been associated with malignancy and has been shown to appear before, concurrently with, or after diagnosis of cancer...

BACKGROUND: Nonalcoholic steatohepatitis (NASH) is an active form of nonalcoholic fatty liver disease. Risk factors for NASH include type 2 diabetes mellitus (T2DM) and obesity. Sodium-glucose cotransporter 2 (SGLT2) inhibitors used to treat T2DM prevent glucose reabsorption in the kidney and increase glucose urinary excretion. Dapagliflozin is a potent, selective SGLT2 inhibitor that reduces hyperglycemia in patients with T2DM and has been demonstrated to reduce some complications associated with NASH in rodent models...

REVIEW
Serge Ginzburg, Jeffrey J Tomaszewski, Alexander Kutikov
Partial nephrectomy is the optimal surgical approach in the management of small renal masses (SRMs). Focal ablation therapy has an established role in the modern management of SRMs, especially in elderly patients and those with comorbidities. Percutaneous ablation avoids general anaesthesia and laparoscopic ablation can avoid excessive dissection; hence, these techniques can be suitable for patients who are not ideal surgical candidates. Several ablation modalities exist, of which radiofrequency ablation and cryoablation are most widely applied and for which safety and oncological efficacy approach equivalency to partial nephrectomy...

Extramedullary hematopoiesis (EMH) is hematopoiesis in organs outside the bone marrow and most frequently occurs in the liver, spleen, and lymph nodes. We report a case of perirenal EMH revealed by kidney biopsy in a patient with primary myelofibrosis. We observed only bilateral kidney enlargement with plain computed tomography (CT) and ultrasonography before obtaining a renal biopsy. We obtained a percutaneous biopsy from the lower pole of the left kidney using ultrasonographic guidance. Ultrasonography just after the renal biopsy revealed no bleeding around the kidney...
