The antitumoral antibiotic, bleomycin, was given by intralesional injection to ten patients with condyloma acuminatum. Our 70 per cent success rate suggests this is a reasonable alternative treatment in the management of anal warts which prove unresponsive to other modalities.
OBJECTIVE: To determine the changes in clinical characteristics and depression levels among patients following treatment for migraine. BACKGROUND: Epidemiologic studies have provided consistent evidence regarding an association between migraine and depression. In Puerto Rico, however, migraine has not yet been systematically investigated. METHODS: A chart review of 144 Puerto Rican patients who presented with migraine, diagnosed according to the International Headache Society criteria, and depression over a 2-year period was performed. The level of depression, before and after migraine treatment, was evaluated using the Zung Self-rating Depression Scale. RESULTS: The mean age of patients was 37.0 +/- 14.4 years; 77.1% were women. More than half (52.8%) reported severe headache and 56.9% reported a monthly frequency of five attacks or more. Nearly 9% were using antidepressant therapy and 8% were under psychiatric treatment. The mean Zung index score at baseline was 50.6 +/- 10.9. Following treatment with triptans, the intensity and frequency of migraine and the Zung index score decreased significantly (P<.00001). A trend for a greater reduction in Zung index scores among patients receiving triptan medications for more than a year was demonstrated (P =.07). CONCLUSIONS: These results indicate that migraine treatment with triptans appears to be effective in decreasing the headache frequency and intensity, and depression levels, independent of antidepressant medication use or psychiatric treatment.
Primary bone marrow lymphomata are infrequent; most of them are of B-cell origin, and those of a T-cell lineage produce mainly both hypercalcemia and osteolytic lesions apparently due to abnormal production of osteoclast-activating factor. We report a 15-year old patient with a primary bone marrow lymphoma: 85% of his infiltrating malignant lymphocytes displayed cytoplasmic mu-chains compatible with a pre-B phenotype. The cells failed to display the CALLA/CD 10 antigen. Serum calcium was 7.5 mEq/L (range 4-5 mEq/L); the bone biopsy of an osteolytic lesion disclosed a large-cell, diffuse non-Hodgkin's lymphoma. No malignant cells were found in the peripheral blood and there were no enlarged lymph nodes. The patient was treated with 6 courses of chemotherapy: hydroxyldaunorubicin, vincristine and prednisone (HOP). Complete remission was achieved and the patient was placed on continuation chemotherapy with daily six-mercaptopurine and weekly methotrexate, together with HOP pulses every three months. The hypercalcemia disappeared together with the fever and the bone pain: the patient has been followed 6 months. Data on this case are discussed together with those previously published in regard to the low prevalence of bone lesions in primary B-cell lymphomas of the bone marrow, and to the similarity of this B-cell malignancy to others that produce both hypercalcemia and bone lesions, i.e. multiple myeloma.
