Hepatocellular cancer provides an ideal model for studying combined modality chemotherapy and radiation interactions. We have treated 20 evaluable patients. All patients received intrahepatic arterial (IA) 5 FU (10 mg/kg/d continuous infusion times 5 minus 9 d) + Adriamycin (3-5 mg/m(2)/d bolus times 5 minus 7 d), and 1,500 and 2,100 rads whole liver radiation (300 rads/day). Additionally, 3 patients have received IA Mitomycin C (8 mg/m(2)). After this "induction" therapy patients usually received IV Adriamycin + 5FU +/- Mitomycin monthly. Objective regressions occurred in 9/20 (45%) and another 9/20 (45%) and stable disease. Median duration of response is 5+ months (range 1+ to 8 months). Improvement in liver function tests occurred in 11/19, and local symptomatic relief in 12/15. Median WBC nadir = 4,000; platelet nadir = 115,000. Mild anorexia, fever, and nausea were frequent, but no radiation hepatitis has been detected. This program seems to result in significant clinical benefit (subjective and objective) in this refractory neoplasm.

Creating an Ellipsys percutaneous arteriovenous fistula after a failed ipsilateral WavelinQ fistula: A case report of an endovascular approach for access restoration.

The introduction of devices for endovascular dialysis access creation (WavelinQ and Ellipsys) offers practitioners more options for access management in dialysis patients. Especially in terms of reducing the usage of central venous catheters, a native fistula is desirable as an initial dialysis access. We present a case in which a failed WavelinQ type fistula was reactivated using the Ellipsys procedure on the same arm.

It was hypothesized that patients treated with BCR prostheses would present higher flexion and better clinical and functional results than those treated with PS implants. This prospective study included thirty-two patients treated for primary knee osteoarthritis and assigned to two matched groups for their demographic characteristics and comorbidities.

A double-blind randomized controlled trial was conducted in 140 patients with hip fracture. After randomization, 68 patients received a single dose of 1 gr of intravenous TXA at the start of the surgery (TXA group), and 72 received a placebo treatment (placebo group).

Monoblock acetabular components with ceramic liners could reduce liner fracture risks during modular acetabular component assembly. This study aims to confirm the safety and clinical performance of the monoblock Maxera Cup in THA.

Aim: Chronic hepatitis C virus infections can lead to liver fibrosis. Appropriate treatment of chronic hepatitis C may result in significant fibrosis reversal. The best method to assess liver fibrosis is an invasive hepatic biopsy.
