1. Capillaroscopic appearance of nailfold vasculature of diabetic nephropathy patients
ABSTRACT Objectives: Diabetic nephropathy is a microvascular complication of diabetes and the most common cause of end-stage renal failure throughout the world. Videocapillaroscopy is a simple and noninvasive method that can display capillaries in the nail bed at the micron level. A few studies have been conducted on detecting retinopathy, another important

2. Retroperitoneoscopic approach for highly complex posterior renal hilar tumors
ABSTRACT Objectives: To show our single-center experience in retroperitoneoscopic approach for highly complex posterior hilar tumors. Minimally invasive nephron sparing surgery for renal hilar tumors is extremely challenging due to their anatomic location, close to the main renal vessels and the collecting system (1). Transperitoneal approach is feasible, b

3. An augmented patient-specific approach to administration of contrast agent for CT renal angiography
ABSTRACT Purpose This hybrid retrospective and prospective study performed on 200 consecutive patients undergoing renal CTA, investigates the opacification of renal vasculature, radiation dose, and reader confidence. Materials and Methods 100 patients were assigned retrospectively to protocol A and the other 100 were allocated prospectively to protocol B

4. Association between endoscopic findings and histopathological confirmation in patients with suspicion of eosinophilic esophagitis
RESUMO CONTEXTO: O diagnóstico da esofagite eosinofílica é realizado através da detecção, em amostra de biópsia esofágica, de 15 ou mais eosinófilos por campo, sendo que os achados endoscópicos isolados não são validados para o diagnóstico da doença. OBJETIVO: Avaliar a associação entre os achados endoscópicos com o diagnóstico histopat

5. The Kidney in Fabry Disease: More Than Mere Sphingolipids Overload
Abstract Fabry disease is a rare cause of end-stage renal disease. Renal pathology is notable for diffuse deposition of glycosphingolipid in the renal glomeruli, tubules, and vasculature. Classical patients with mutations in the α-galactosidase A gene accumulate globotriaosylceramide and become symptomatic in childhood with pain, gastrointestinal disturbanc

6. Primary renal angiosarcoma with extensive hemorrhage: CT and MRI findings
ABSTRACT Primary angiosarcomas of the kidney are very rare, but highly aggressive tumors showing poor prognosis. Patients frequently complain of flank pain, hematuria, or a palpable mass. We present a case of primary renal angiosarcoma occurring in a 61-year-old man. CT images depicted a huge exophytic mass (16 cm in diameter) in the right kidney, exhibiting

7. Radiotherapy and immune response: the systemic effects of a local treatment
Technological developments have allowed improvements in radiotherapy delivery, with higher precision and better sparing of normal tissue. For many years, it has been well known that ionizing radiation has not only local action but also systemic effects by triggering many molecular signaling pathways. There is still a lack of knowledge of this issue. This rev

8. Laparoscopic splenectomy: a new approach
OBJECTIVES: To introduce a new laparoscopic splenectomy (LS) approach. METHODS: Sixteen patients underwent LS with general anaesthesia and carbon dioxide pneumoperitoneum. The details of the surgery are as follows: 1. The omentum was incised along the greater curvature and retracted as much as possible to expose the pancreatic body and tail. 2. The right a

9. Off-pump Coronary Artery Bypass Grafting in Moyamoya Disease: a Case Report
Abstract Moyamoya disease is a rare, idiopathic, progressive, occlusive disease of the internal carotid artery characterized by the development of collateral vasculature in the brain base. In patients with accompanying coronary artery disease, cardiopulmonary bypass posses a potential risk for perioperative cerebral ischemic complication. Herein, we report a

10. Appendicular origin and structure of the spur of Vochysiaceae flowers
ABSTRACT Floral nectaries are linked with animal pollinators and floral specialization, characterizing some plant groups, such as the mostly Neotropical Vochysiaceae. The phylogeny of these plants has been revised based on molecular data, but their conspicuous spurs were mostly neglected. The appendicular or receptacular origin of these spurs has been discus

11. Histological changes caused by meclofenamic acid in androgen independent prostate cancer tumors: evaluation in a mouse model
ABSTRACT Meclofenamic acid is a nonsteroidal anti-inflammatory drug that has shown therapeutic potential for different types of cancers, including androgen-independent prostate neoplasms. The antitumor effect of diverse nonsteroidal anti-inflammatory drugs has been shown to be accompanied by histological and molecular changes that are responsible for this be

12. Step-by-Step robotic heminephrectomy for duplicated renal collecting system
Introduction A duplicated renal collecting system is a relatively common congenital anomaly rarely presenting in adults. Aim In this video we demonstrate our step-by-step technique of Robotic heminephrectomy in a patient with non-functioning upper pole moiety. Materials and Methods Following cystoscopy and ureteral catheter insertion the patient was
