This retrospective analysis describes the clinical characteristics, treatment, and outcome of 19 patients aged 80 years or older with odontoid fractures. The fractures were due to falls in 15 patients (78.9%) and were associated with motor-vehicle accidents in four. Type III fractures were seen in three patients and type II fractures in 16. No patient(More)
BACKGROUND Patients with papulopustular rosacea have a higher density of Demodex folliculorum mites on their faces than normal subjects but the role, if any, of their mites in initiating inflammation is disputed. Selective antibiotics are effective in reducing the inflammatory changes of papulopustular rosacea, but their mode of action is unknown. (More)
The clinical, histologic, and immunofluorescent findings in 86 cases of pyoderma gangrenosum seen at the Mayo Clinic between 1970 and 1983 were reviewed. Males and females were affected in equal numbers. The most frequent site of lesions was the leg. Sixty-seven patients (78 per cent) had associated systemic disease, with arthritis and inflammatory bowel(More)
A 69-year-old woman developed seizures after cerebral angiography immediately preceded by coronary angiography. The preceding coronary angiography resulted in hyperconcentration, hyperosmolar loading, and overdosing of the nonionic contrast medium. A CT examination demonstrated gyriform enhancement throughout the left cortex and the left basal ganglia.(More)
BACKGROUND The cause of rosacea is unknown; among other factors a causative role has been postulated for the hair follicle mites Demodex folliculorum and Demodex brevis. OBJECTIVE Our purpose was to compare the population density of Demodex mites in facial skin of defined categories of patients with rosacea with control subjects. We also assessed the(More)
The major surface antigen of Pneumocystis carinii, a life-threatening opportunistic pathogen in human immunodeficiency virus-infected patients, is an abundant glycoprotein that functions in host-organism interactions. A monoclonal antibody to this antigen is protective in animals, and thus this antigen is a good candidate for development as a vaccine to(More)
Pyoderma gangrenosum (PG) has four distinctive clinical and histologic variants. Some have morphologic and histologic overlapping features with other reactive neutrophilic skin conditions. PG often occurs in association with a systemic disease, and the specific clinical features of the skin lesion may provide a clue to the associated disease. Management of(More)
Approximately 12 million Americans undergo spinal manipulation therapy (SMT) every year. Renewed interest in this method requires an analysis of its reported risks and possible benefits. This review describes two patients with spinal cord injuries associated with SMT and establishes the risk/benefit ratios for patients with lumbar or cervical pain. The(More)
