This study was done to determine whether [99mTc]methoxyisobutyl isonitrile (RP30), a nonredistributing myocardial perfusion agent, could be used to quantify regional myocardial blood flow distribution during ischemia and reperfusion, employing sequential injections of tracer, tomographic imaging, and appropriate image subtraction. Dogs underwent transient(More)
The main objective of this study is to analyze results obtained with hydroxyapatite bone cement (HABC) ossiculoplasties. This is a retrospective study of a case series. This study was conducted in an academic hospital and tertiary referral center. A total of 127 ossiculoplasties using HABC were evaluated. Ears were divided into three groups according to(More)
The authors report ten cases of sudden deafness treated by piracetam. In eight cases there was a complete recovery, in one case there was a partial recovery and in one it was a failure. There was observed in two cases a rise in the compound action potential of the electrocochleography measured after 30 minutes of the infusion in comparison with that(More)
The aim of this study was to test the effectiveness of two types of carboxymethylcellulose (CMC), at different doses, for the prevention of tartaric precipitations in two white wines (Pinot Blanc and Chardonnay), in comparison with metatartaric acid and a commercial arabic gum. After the addition of the additives to the wines, the mini-contact test was(More)
OBJECTIVE To analyze the results obtained with hydroxyapatite bone cement (HABC). PATIENTS A total of 73 ossiculoplasties with HABC were evaluated. Ears were divided into 4 groups: Group 1: Reinforcement of the incudo-stapedial joint with HABC; Group 2: Reconstruction of an incus long process defect with HABC; Group 3: Partial ossicular reconstruction(More)
To determine whether the current "gatekeeper" controls on health care lead to an increase in treatment delay and morbidity of acute appendicitis in children, we reviewed the experience with this disease at a large children's hospital over a 10-year period. One hundred seven consecutive children 18 years and younger operated on for acute appendicitis from(More)
Traditional reconstruction methods of osseous defects within the tympanic frame, most often being the atticotomy, within the framework of chronic otitis media surgery, still do not produce stable or definitive results, usually due to displacement or partial lyse of the transplanted material (cartilage, bone ...). The reconstruction procedure with the aid of(More)
Anterior tympanic perforations are actually the most difficult to close and a number of different techniques exist. This article represents the author's surgical procedure for type I tympanoplasties (myringoplasties) for this kind of perforation using the tragal cartilage and the perichondrium after preparation (revival, cleaning) of the perforation edge(More)
