Acquired spinal stenosis secondary to an expanding thoracic vertebral hemangioma.

Intraosseous hemangioma is a slow-growing primary benign neoplasm of capillary, cavernous, or venous origin. The most common type is the cavernous hemangioma, composed of large thin-walled vessels and sinuses lined by endothelial cells. Although found in any bone, hemangioma is most common in the vertebrae, where it represents 2-3% of all radiographically detectable spinal tumors. Most spinal hemangiomas are solitary, asymptomatic lesions of the vertebral body, with 10-15% showing concomitant involvement of the posterior elements. Rarely, the lesion is located to the posterior arch. An unusual case of an expanding vertebral hemangioma isolated to the posterior elements of T9 is presented.

Journal of Manipulative & Physiological Therapeutics: a bibliographic analysis.

The first 9 years of the Journal of Manipulative and Physiological Therapeutics (JMPT) (1978-1986) were surveyed to determine concentrations of research activity, educational backgrounds of contributors, sources of funding for chiropractic science, and the volume and kinds of research in chiropractic. Most articles were authored by chiropractors but a fourth of all articles included contributors with scientific/academic doctorates. Most chiropractors were affiliated with a chiropractic college, but collaboration among chiropractic colleges was rare. A recent increase in contributions from private practitioners was also evident. Authors with medical training were uncommon (6%). National College and Canadian Memorial together accounted for 43% of all articles, and 72% of papers whose authors gave chiropractic college affiliations. Authors acknowledged 30 funding sources, and the Foundation for Chiropractic Education and Research (FCER) accounted for a third of all grants (18 of 55). Empirical studies increased in frequency from 1978 to 1986, but accounted for less than half of the papers. Case reports have been the most common form of original data report; 39 were published in JMPT during the 9 year period. Controlled clinical trials of chiropractic healing methods were extremely rare (3 of 334 papers). A need for greatly expanded clinical research in chiropractic is suggested.

Atypical brachydactyly.

A case of atypical brachydactyly is reported with clinical and radiographic findings. A differential diagnosis is discussed. In light of the lack of corrective surgical techniques, conservative management is considered, including genetic consultation to prevent the deformity in future generations.

Extraspinal enthesopathy caused by isotretinoin therapy.

OBJECTIVE: To discuss a case of diffuse peripheral enthesopathy in a patient previously treated with long-term isotretinoin (Accutane) for severe acne. CLINICAL FEATURES: A 47-year old man with 1 month history of moderate neck and right upper extremity pain, with hypoesthesia of the right second and third fingers. Palpable bony prominences around multiple superficial joints were noted on physical examination, raising the initial question of osteochondromatosis. Multiple active acne pustules were noted. A limited skeletal survey demonstrated diffuse peripheral enthesophyte formation and hyperostoses, resembling those of diffuse idiopathic skeletal hyperostosis, but without accompanying spinal changes. A history of long-term Accutane therapy was then elicited. INTERVENTION AND OUTCOME: The enthesopathy was believed to represent an asymptomatic, longstanding, iatrogenically induced abnormality. No specific therapy or follow-up was indicated. The patient had discontinued use of Accutane years ago. Cervical symptoms improved with four sessions of cervical traction and nonsteroidal anti-inflammatory medications, but upper extremity symptoms were refractory. CONCLUSION: Accutane-induced enthesopathy should be considered in individuals with correlating radiologic and clinical features and history of retinoic acid therapy for acne. This should be a diagnosis by exclusion, after eliminating other potential causes of peripheral enthesopathy, particularly diffuse idiopathic skeletal hyperostosis, seronegative spondylarthropathy, and fluorosis.

Stress X-rays and the low back pain patient.

This study was undertaken to determine if demographic, historical and/or clinical information would be helpful in predicting the presence of abnormal motion depicted on a stress radiograph (flexion, extension and lateral bending views). A total of 72 patients were divided into "normals" and "abnormals" based on the presence of abnormal sequential intersegmental vertebral motion as demonstrated on the stress radiographs. Demographically and historically, the "normal" and "abnormal" groups were essentially the same. Clinical data also failed to show any statistically significant differences between the two groups. Other radiographic findings (scoliosis, degenerative disease, and foraminal encroachment) did not show any significant differences. The value of demographic, historical and/or clinical information as input into the formulation of a protocol for stress radiography is questioned. Suggestions for further research are given.
