A robust, highly sensitive system is described for monitoring the concentration of positron emitting radioisotopes contained within arterial blood continuously withdrawn during PET studies of the brain. Utilizing a specially designed flow-through bismuth germanate detector, gammas are more effectively counted, replacing the less efficient method of positron(More)
BACKGROUND The standard Heller myotomy (SM) for achalasia extends 1 to 2 cm on to the stomach. The authors perform an extended myotomy (EM) (>3 cm) with the goal of reducing postoperative dysphagia. This study examines the long-term efficacy and durability of EM compared with SM. METHODS Patients with achalasia who underwent a laparoscopic Heller myotomy(More)
The successful management of multi-space orofacial odontogenic infections involves identification of the source of the infection, the anatomical spaces encountered, the predominant microorganisms that are found during the various stages of odontogenic fascial space infection, the impact of the infectious process on defense systems, the ability to use and(More)
Tunneling as a technique for augmentation of an atrophic maxilla has been described in the literature. The use of this technique has presented several prosthodontic problems, such as diffusion of material into adjacent tissues, incorrect positioning of the material on the ridge, and inadequate ridge height. Use of the transpositional flap technique(More)
Liposuction is often used for the treatment of gynecomastia. Blunt liposuction cannulas can remove the fat but are not very effective in fibrous breast tissue, which requires open excision. Ultrasound-assisted lipoplasty has been advocated for gynecomastia because it effectively removes the fat from fibrous areas. An alternative treatment is a sharp cutting(More)
Coenzyme Q(10) (CoQ(10)) exists in human tissue, and is indispensable to mitochondrial enzymes of respiration. CoQ was administered to children with preclinical muscular dystrophy, CoQ enzymology was emphasized, and serum creatine phosphokinase, CPK, (ATP:creatine N-phosphotransferase, EC 2.7.3.2) was repeatedly monitored.A 40-week treatment of an infant,(More)
Silicone implant rupture is well recognized, particularly with the thin-walled implants inserted some years ago. On occasions a chronic granulomatous inflammation has been noted if silicone globules have infiltrated the tissues. The rupture may occur apparently spontaneously or after trauma, including attempts at external closed capsulotomy. The case report(More)
