Abstract: We treated 11 psoriatic patients with topical 1 alpha,24-dihydroxycholecalciferol, a new synthetic analogue of active vitamin D3. In 10 of 15 tests the lesions cleared completely within 1-4 weeks, although some relapses occurred shortly after cessation of treatment. There were no side-effects. We suggest that 1 alpha, 24(OH)2D3 merits further investigation as a potentially useful topical therapy for psoriasis.
Which is the apt title for the abstract? option1: Successful treatment of psoriasis with topical application of active vitamin D3 analogue, 1 alpha,24-dihydroxycholecalciferol. option2: Laser therapy of bowenoid papulosis and Bowen's disease.

Ex Output:
Successful treatment of psoriasis with topical application of active vitamin D3 analogue, 1 alpha,24-dihydroxycholecalciferol.

Abstract: Thirty-five patients with complete myelopathies secondary to cervical spine fractures from C-4 to C-7 underwent spinal decompressions and fusions between 1975 and 1981. Twenty-five of these patients underwent simultaneous nerve root decompressions, 23 with an accompanying anterior decompression and fusion and 2 with an accompanying posterior fusion. Substantial recovery of nerve root function occurred in 15 of these patients. A posterior reduction and fusion without nerve root decompression was performed in each of the remaining 10 patients. None of these patients demonstrated a significant improvement neurologically. Operation for nerve root decompression is indicated in selected victims of spinal cord injury.

Abstract: Recognizing that not all patients with low back pain have lumbar disc disease, the authors began to inject facet joints in June 1982 and have experience now with 21 patients, each injected under fluoroscopic control with a mixture of local anesthetic and steroid. One technical problem occurred when large osteophytes blocked access to the facet joints. Otherwise, there were no complications and minimal morbidity. Most patients (15 of 20; 75%) had an initial response, but a much smaller number (six of 18 followed more than three months; 33%) had a lasting response. Repeat injections, when done, always led to temporary improvement but rarely to lasting relief (one of five; 20%). Three factors characterized the patients: a negative screening examination for other causes of back pain or sciatica; back pain with tenderness localized over one or more facet joints; and radiologic changes of degenerative joint disease within the facet joints. Facet joint disease may be a significant cause of low back pain. The above three criteria are useful in clinical identification of patients with this problem. Facet joint injections play an important role in the diagnosis and treatment of low back pain.
