Definition and diagnostic criteria of refractory ascites and hepatorenal syndrome in cirrhosis

Myofibroblasts are a unique group of smooth-muscle-like fibroblasts that have a similar appearance and function regardless of their tissue of residence. Through the secretion of inflammatory and an...

Methods and apparatus are provided for renal neuromodulation using a pulsed electric field to effectuate electroporation or electrofusion. It is expected that renal neuromodulation (e.g., denervation) may, among other things, reduce expansion of an acute myocardial infarction, reduce or prevent the onset of morphological changes that are affiliated with congestive heart failure, and/or be efficacious in the treatment of end stage renal disease. Embodiments of the present invention are configured for percutaneous intravascular delivery of pulsed electric fields to achieve such neuromodulation.

Methods and apparatus for renal neuromodulation

A method and apparatus for treatment of heart failure, hypertension and renal failure by stimulating the renal nerve. The goal of therapy is to reduce sympathetic activity of the renal nerve. Therapy is accomplished by at least partially blocking the nerve with drug infusion or electrostimulation. Apparatus can be permanently implanted or catheter based.

Effects of lumbar sympathetic block on kidney function in cirrhotic patients with hepatorenal syndrome.

We report on four patients of our own and another thirty-six from the literature, who developed almost identical and unusual clinical syndromes after surgical treatment of hydatid disease of the liver, with the aim of showing the extremely serious nature of the problem that can ensue. An association of four factors seems to be necessary to promote caustic sclerosing cholangitis: a) injection of a scolicidal agent (formalin, hypertonic saline, ethanol, silver nitrate or iodine solution) into the cyst cavity; b) a communication between the cyst and the biliary tree; c) a condition that prolongs the exposure of the biliary tree to the scolicidal; and d) a particular sensitivity to the scolicidal agent. While this last condition cannot be anticipated, we may justifiably conclude that surgeons should not inject a scolicidal solution into the hydatid cyst, but prevent intra-abdominal diffusion of the parasite by using hydrogen peroxide, gauze pads moistened by a scolicidal solution or by preoperative chemotherapy with albendazole. Caustic sclerosing cholangitis has an earlier onset of symptoms and a more rapidly progressive nature than primary sclerosing cholangitis. In foresight, serum alkaline phosphatase should be monitored and, when raised, a retrograde endoscopic cholangiogram and/or a liver biopsy should be performed. Digestive shunt surgery should be avoided and the possibility of liver transplantation has to be periodically evaluated.

Tumor necrosis factor alpha inhibits collagen alpha 1(I) gene expression in rat hepatic stellate cells through a G protein

A case is reported of collagenous gastrobulbitis on collagenous colitis in a 57-year-old woman with a 6-month history of watery diarrhea. Low serum levels of total proteins and albumin and increased fecal elimination of alpha1-antitrypsin were the only abnormal laboratory test results. Biopsy specimens from the colon, rectum, antrum, fundus, and duodenal bulb showed a thick subepithelial band composed of ultrastructurally normal collagen immunohistochemically negative for collagen IV and laminin. The diarrhea resolved with prednisone and responded to this treatment after a relapse 6 months later. One year later the patient developed severe alimentary intolerance and secondary weight loss. This symptom also responded to the same treatment. However, the collagen deposition did not disappear in the second biopsy samples of colonic and gastric mucosa. Only six cases have been previously reported with gastric and/or duodenal subepithelial collagenous deposition. Four were associated with collagenous colitis. One of these presented a subepithelial collagenous band in the terminal ileum. All these features suggest that this collagen deposition may affect the entire digestive tract with variable intensity, extension, and symptoms.
