Implant surgery and oral anticoagulant therapy: case report.

Objectives: This work aims to assess the risks both thromboembolic that bleeding of a management protocol "non-conservative" in patients on oral anticoagulant therapy (OAT) to be undergoing implant surgery.

Materials And Methods: We decided to take a surgical "non-conservative" protocol, to insert four implants in the aesthetic zone, without using flapless surgery and the surgical template. In accordance with the hematologist, the value of INR is lowered and warfarin was replaced with heparin low molecular weight, to have a better coagulation's control.

Digital work-flow.

Objective: The project presents a clinical case in which the digital work-flow procedure was applied for a prosthetic rehabilitation in natural teeth and implants.

Materials: Digital work-flow uses patient's photo for the aesthetic's planning, digital smile technology for the simulation of the final restoration and real time scanning to register the two arches. Than the scanning are sent to the laboratory that proceed with CAD-CAM production.

A prospective, double-blind, multicenter, randomized trial comparing ertapenem 3 vs >or=5 days in community-acquired intraabdominal infection.

Severe secondary peritonitis is diagnosed in only 20-30% of all patients, but studies to date have persisted in using a standard fixed duration of antibiotic therapy. This prospective, double-blind, multicenter, randomized clinical study compared the clinical and bacteriological efficacy and tolerability of ertapenem (1 g/day) 3 days (group I) vs >or=5 days (group II) in 111 patients with localized peritonitis (appendicitis vs non-appendicitis) of mild to moderate severity, requiring surgical intervention. In evaluable patients, the clinical response as primary efficacy outcome were assessed at the test-of-cure 2 and 4 weeks after discontinuation of antibacterial therapy.

[Pancreatic pseudocysts: a rare complication of the Warren distal splenorenal shunt].

The authors report a case of distal splenorenal shunt with splenopancreatic disconnection complicated by a huge pancreatic pseudocyst. This complication has not been described in the literature so far. The etiology and the opportunity of the splenopancreatic disconnection are discussed.

[Angiomyolipoma of the kidney: a case of spontaneous rupture].

After reporting the general features of renal angiomyolipoma (AML), either isolated or associated to other conditions (Bourneville sclerosis, Wunderlich's syndrome), the Authors discuss a case complicated by perirenal spontaneous hematoma, undergone emergency operation (simple nephrectomy). At a 3 year follow-up the patient is in good general and local conditions (negative TC, normal renal function, preexistent hypertension disappeared). Literature is reviewed and some considerations about diagnosis and surgical tactics are reported.

Peritoneovenous shunt occlusion. Etiology, diagnosis, therapy.

Electronic pressure testing of every LeVeen valve has practically eliminated mechanical malfunction as a cause of shunt failure. Nonetheless, failures do occur and in a series of 240 cases, early or late shunt failure occurred in 29 patients. Thirty-five additional cases of failures were either referred by other physicians over a period of 6 years or information and x-rays were accumulated by direct contact.

Radiofrequency thermotherapy, local chemotherapy, and arterial occlusion in the treatment of nonresectable cancer.

Localized radiofrequency thermotherapy (RFTT) has been effective by itself in debulking cancers but has not accomplished total eradication by itself. Occlusion of the regional artery supplying the tumor drastically reduces the arterial pressure distal to occlusion and further impairs tumor blood flow leading to an accentuation of the temperature differentiation achieved by the normal tissue and tumor. Radiofrequency thermotherapy with vascular occlusion is combined with direct injection of an effective chemotherapeutic agent into the tumor.

Evaluation of peritoneovenous shunt patency with Tc-99m labeled microspheres.

The LeVeen peritoneovenous shunt (PVS) was investigated in 40 cirrhotic patients with refractory ascites. Five millicuries of Tc-99m-tagged human albumin microspheres (15-36 microns) were injected into the peritoneal cavity between the umbilicus and the left anterior superior iliac spine. The radiotracer was always detectable by scintigram in the lungs when the shunt was patent.

Effects of isovolumic hemodilution on massive pulmonary emboli.

Massive pulmonary emboli obstruct the pulmonary outflow tract and release vasoactive amines that further increase vascular resistance in the pulmonary vascular bed. Lowering blood viscosity by isovolumic hemodilution has been suggested as a possible therapeutic modality to increase pulmonary blood flow. This study was performed to determine if hemodilution could affect the aberrancies caused by massive emboli.
