OBJECTIVE Cervical epidural spinal infection, which includes diskitis, osteomyelitis, and/or epidural space infection, is an uncommon disease, and the MR imaging features have not been fully described. Accordingly, the objective of this study was to determine the MR imaging findings in a large series of patients with this condition, with emphasis on(More)
Folate-dependent one-carbon metabolism is required for the synthesis of purines and thymidylate and for the remethylation of homocysteine to methionine. Methionine is subsequently adenylated to S-adenosylmethionine (SAM), a cofactor that methylates DNA, RNA, proteins, and many metabolites. Previous experimental and theoretical modeling studies have(More)
PURPOSE Investigation of a technique for nonsurgical female sterilization. MATERIALS AND METHODS A custom designed platinum microcoil with Dacron fibers was placed unilaterally into a fallopian tube and uterine horn of 10 rabbits after transcervical selective tubal catheterization with use of fluoroscopic guidance. The contralateral uterus and fallopian(More)
PURPOSE This study reports the authors' experience with long-term follow-up of 100 consecutive peripherally inserted, subcutaneous arm ports for central venous access. MATERIALS AND METHODS One hundred patients with subcutaneous arm ports inserted by interventional radiologists were retrospectively studied. Data were collected from the patients' medical(More)
Recent advances in the diagnosis and treatment of voice disorders necessitate the need for accurate and reliable objective voice measurements. There are many instruments commonly used to analyze voice data. Many, if not most, of these instruments have not been adequately tested for reliability or consistency. This study evaluates the intrasubject(More)
Brainstem evoked response audiometry (ABR) permits auditory pathway assessment without the need for voluntary response. Brainstem responses are unaffected by attention, drugs, and most other confounding conditions. Consequently, if ABR could be used to determine hearing threshold in the speech frequencies, it would have great value for patients who are(More)
Gastroesophageal reflux disease (GERD) is known to cause a variety of symptoms that lead a patient to seek otolaryngologic care. New advances in the treatment of GERD have enabled otolaryngologists to eliminate most of the signs and symptoms caused by acid reflux. Omeprazole, the most recent pharmacologic advancement, has been reported to be universally(More)
Myasthenia gravis is a neuromuscular disease that presents clinically as fluctuating weakness of one or more skeletal muscle groups. Weakness becomes more severe with exercise and improves with rest. The disease is caused by an autoimmune reaction at or near the post-synaptic nicotinic acetylcholine receptor. The results of this immune reaction are the(More)
