Marginal bone preservation in single-tooth replacement: a 5-year prospective clinical multicenter study.

Background: Few long-term studies are available comparing immediate and conventional loading protocols of implant-supported single-tooth replacement.

Purpose: The aim of the present randomized controlled clinical trial was to evaluate prospectively the 5-year clinical and radiological outcome of immediate functional loading implants used in single-tooth replacement.

Materials And Methods: One hundred fifty-one subjects, who required single-tooth rehabilitation in the area from position 15 to 25 and from 35 to 45, were enrolled in eight private clinics in Italy.

Effect of immediate functional loading on osseointegration of implants used for single tooth replacement. A human histological study.

Objective: To analyze hard tissue reactions to immediate functionally loaded single implants that were installed either with a conventional drill preparation procedure or with an osteotome preparation technique.

Materials And Methods: Thirteen subjects with two sites requiring single tooth rehabilitation by means of implants volunteered for the study. Each subject received one test (immediate functionally loaded) and one control (non-loaded) implant.

Recurrent aortoduodenal fistula.

Aortoenteric fistula is defined as a communication between the aorta and an adjacent loop of the bowel and is often the cause of devastating upper gastrointestinal tract bleeding with only few survivors. According to the etiology, the aortoenteric fistulas are classified as primary aortoenteric fistula or secondary aortoenteric fistula (SAEF) after previous aortic surgery. The recurrence of a fistula on a previous SAEF is defined as recurrent aortoenteric fistula and is reported only in a few rare cases occurring within an unpredictable period from the previous surgical treatment.

Immediate functional loading of implants in single tooth replacement: a prospective clinical multicenter study.

Objectives: The aim of the present study was to evaluate the outcome of immediate functional loading of implants in single-tooth replacement using two different installation procedures.

Material And Methods: One hundred and fifty-one subjects, who required single-tooth rehabilitation in the area of 15-25 and 35-45, were enrolled in eight private clinics in Italy. The implant sites were randomly allocated to one of the following treatment groups.

Isolated injury of the superior mesenteric artery caused by a lap belt in a child.

Isolated vascular injuries are rare in cases of blunt abdominal trauma, and superior mesenteric artery injury is extremely rare but potentially lethal. The incidence of this kind of life-threatening injury has increased in recent years. The diagnosis of these isolated injuries is difficult, and its delay is associated with a higher morbidity and mortality.

Contrast-enhanced sonographic appearance of hepatocellular carcinoma in patients with cirrhosis: comparison with contrast-enhanced helical CT appearance.

Objective: We sought to investigate the efficacy of contrast-enhanced sonography using a second-generation contrast agent for the evaluation of hepatocellular carcinoma in patients with cirrhosis by comparing the results to those obtained with contrast-enhanced helical CT.

Subjects And Methods: Between October 2002 and March 2003, 74 patients with cirrhosis (60 men and 14 women; age range, 47-80 years; mean age, 67 years) who had a single nodule of hepatocellular carcinoma were selected to be studied from a cohort of 437 patients with cirrhosis. The size range of the 74 nodules was 9-65 mm (mean, 28.

Acute appendicitis mimicking infectious enteritis: diagnostic value of sonography.

Objective: To verify the role of sonography in screening of acute appendicitis in patients admitted to an infectious disease unit for suspected acute infectious enteritis.

Methods: One hundred eighty consecutive patients (102 male and 78 female; age range, 5-72 years; mean age, 31 years) admitted for suspected infectious enteritis or typhoid fever were prospectively studied with abdominal sonography within 48 hours after admission. None of the patients had peritoneal irritation.

Percutaneous sonographically guided saline-enhanced radiofrequency ablation of hepatocellular carcinoma.

Objective: The purpose of our study was to analyze the efficacy, side effects, and short-term complications of saline-enhanced percutaneous radiofrequency ablation performed under sonographic guidance in a series of cirrhotic patients with hepatocellular carcinoma. SUBJECTS AND METHODS. Between September 2000 and June 2002, 84 patients (55 men and 29 women) with cirrhosis who ranged in age from 48 to 74 years (mean age, 64 years) and who had 95 hepatocellular carcinomas (seven patients had two tumors and two patients had three tumors) were treated with high frequency-induced thermotherapy.

[Subphrenic abscess during the course of acute brucellosis: diagnosis and treatment with percutaneous sonographically-guided drainage].

Abscess formation during the course of acute brucellosis is a rare event. A case of subphrenic abscess, the first to our knowledge, is described. A 49 years-old male patient with fever and a mild increase in ALT and gamma-GT was referred to our Institution.
