Neurological manifestations of osteoid osteoma
Article Abstract:
Osteoid osteoma is a benign tumor of bone that is often associated with intense pain. Both referred pain (pain felt in one site that has its origin in another) and radicular-like pain (affecting nerve roots) are described. The pain is described as an aching, it is worse at night, and it is relieved by salicylates (aspirin). The femur and tibia are the bones most commonly affected and the lesions are usually near the shaft. This neoplasm of the bone is found two to three times more commonly among boys than girls, and does not seem to affect people after their 20s. The clinical diagnosis of osteoid osteoma can be difficult, especially since the characteristic radiological findings may not be seen until late in the course of the disease. The diagnosis is seldomly made less than six months from the onset of symptoms and may occur many years later. Frequently, osteoid osteoma may mimic neurological diseases, particularly lesions of the spinal cord, which may delay accurate diagnosis. Since osteoid osteoma is associated with a number of symptoms, a study of 38 patients was conducted to analyze the clinical and radiological features of the lesion with reference to signs and symptoms that are suggestive of a neurological disorder. Twenty-nine patients had lesions of the femur or tibia. The mean duration from the onset of symptoms to the time of diagnosis was slightly over 13 months. Examination of plain X-rays in 30 patients (79 percent) were strongly suggestive of osteoid osteoma; six patients had normal X-rays. Radionucleotide scans were done in 17 patients, 10 of which were positive. The other seven were abnormal but not diagnostic for osteoid osteoma. Thirty-six patients had excision biopsies with histological confirmation of the diagnosis of osteoid osteoma. A computed tomogram (CT scan) is recommended, since plain X-rays, although abnormal, may not be diagnostic, and radionucleotide scanning should be done even if X-rays are entirely normal. Treatment of osteoid osteoma consists of excision of the tumor and some surrounding tissue. Diagnosis of this lesion requires both an accurate history and an awareness of the possibility of the presence of the lesion. (Consumer Summary produced by Reliance Medical Information, Inc.)

Designing your office for technology
Article Abstract:
The ways to design a facility that optimizes the use of technology in the dental office are illustrated. Dentists need to make appropriate decisions regarding the type of technology they choose to integrate into their offices, and they need to understand the way the technology would be installed and integrated.
