Autologous Unpurged Bone Marrow Transplantation for Acute Non Lymphoblastic Leukemia in First Remission

Forty consecutive adult patients under the age of 50 with acute non-lymphoblastic leukemia (ANLL) in first complete remission, underwent autologous bone marrow transplantation (ABMT) between March 1984 and April 1990. The conditioning regimen employed included cyclophosphamide and total body irradiation, followed by the administration of unpurged ABMT. The median time from diagnosis to transplant was 7 months (3-15 months), and the median time from complete remission to ABMT was 4 months (range 3-9 months). Twenty-two (51%) patients remain in complete remission 6-81 months (median 24 months) after ABMT.

The causes of death were, recurrent leukemia (11 patients), parenchymal toxicities such as acute respiratory distress syndrome and veno-occlusive disease (3 patients), hemorrhage (2 patients) and infection (2 patients). Eleven patients relapsed after 3-12 months (median 5 months). This study has produced survival data comparable to those of other institutions employing TBI for either allo or autotransplants.     

Malignant evolution of presumed benign lesions in the brain in neurofibromatosis: case report

We report a patient suffering from neurofibromatosis type 1 in whom neoplasms developed from the areas of altered signal which are generally considered benign and typical of the disease. MRI, despite two previous examinations 3 and 2 years before development of the tumour, gave no clue to an unfavourable outcome. Received: 18 January 1996 Accepted: 24 October 1996     

Autologous bone marrow transplantation as adjuvant treatment for high-risk Hodgkin's disease in first complete remission after MOPP/ABVD protocol.

Fifteen patients with very poor prognosis Hodgkin's disease in remission after MOPP/ABVD regimen, were treated with high-dose chemotherapy (HDC) and autologous marrow transplantation (ABMT) immediately after achieving complete remission (CR). Thirteen patients (86.6%) remain alive in unmaintained CR at a median time of 36 months (range 10-64 months) post-transplant. In the other two patients reasons for failure included relapse of Hodgkin's disease (one patient) and death due to interstitial pneumonitis secondary to carmustine therapy. These patients were compared with a historical control group consisting of 24 patients with the same poor prognostic factors, who achieved CR with MOPP/ABVD and did not receive other treatment. Eight out of 24 patients (33%) remain alive and well in unmaintained CR at a median time of 42 months (range 19-83 months). The administration of MOPP/ABVD combined with HDC and ABMT was not associated with an increased incidence of major toxicity. The results achieved support the early sequential treatment of a highly effective drug combination followed by HDC/ABMT that can substantially improve the likelihood of cure in these advanced stage very poor prognosis Hodgkin's disease patients.     

A manual bead assay for the determination of absolute CD4+ and CD8+ lymphocyte counts in human immunodeficiency virus-infected individuals.

CD4+ T lymphocytes are currently the most common surrogate marker indicating disease progression in individuals infected with human immunodeficiency virus (HIV). Since the cost of enumerating lymphocyte phenotypes is quite high, an inexpensive bead assay analyzed by light microscopy (cytosphere assay; Coulter Corporation, Hialeah, Fla.) was developed as an alternative method for counting CD4+ and CD8+ T lymphocytes. To evaluate the reliability of the cytosphere assay, heparinized blood was collected from 117 HIV-infected individuals and tested for both CD4+ and CD8+ lymphocytes by flow cytometry and the cytosphere assay. The Pearson correlation coefficient of the cytosphere assay compared with that of flow cytometry for CD4+ T lymphocytes was 0.93, with mean values +/- standard deviations of 534 +/- 509 by flow cytometry and 499 +/- 477 by the cytosphere assay. The correlation coefficient for CD8+ T lymphocytes was 0.86, with mean values of 831 +/- 543 by flow cytometry and 746 +/- 472 by the cytosphere assay. The sensitivity and specificity of the cytosphere assay in determining absolute CD4+ T-lymphocyte counts of less than 200/microliters were 97.6 and 94.7%, respectively. The positive predictive value was 90.9%, and the negative predictive value was 98.6%. The cytosphere assay was highly correlative to flow cytometry in determining CD4+ and CD8+ T-lymphocyte counts among HIV-infected patients. The ease and limited resources needed to perform this test make it ideal in developing countries and other areas where technology and finances are limited.     

Angiomorphology of the ciliary body in diabetic disease

The authors describe the pathological changes in the vascular structures of the ciliary body occuring in diabetes mellitus. The lesions consist of a quantitative reduction in the number of vessels and in modifications of diameter and arborisation. Changes include sectoral thinning, isolated and grouped aneuryms and marked tortuosity. These findings are thought to be constant in the diabetic patient and are probably involved in the various aspects of diabetic eye disease affecting other structures besides the ciliary body. The group of vascular changes in the ciliary body in diabetes may aptly be termed "diabetic ciliopathy".     

Diffuse pulmonary tumor microemboli from prostatic carcinoma with an associated fibrous histiocytic sarcoma

Diffuse tumor microemboli to the lungs from prostatic carcinoma are extremely rare, with only six reported cases in the literature published in English. Here a seventh case is reported. The patient resembled the previously reported cases in the following ways: (1) There were minimal chest x-ray findings; (2) there was no other evidence of significant parenchymal or lymphangitic tumor involvement; and (3) pulmonary hypertension developed, but without signs of cor pulmonale. The case was even more unusual because of the presence of an apparent second neoplasm, ie, a malignant fibrous histiocytic sarcoma primary in the chest wall. There were wide-spread "collisional metastases" (metastases from each malignancy at the same site).     

Hemichorea due to a cavernous angioma of the caudate. Case report of an aged patient

A 75 year old man presented left hemichorea due to a cavernous angioma of the head of the contralateral caudate. Cavernous angiomas of the basal ganglia are an infrequent cause of hemichorea especially in older subjects but should be considered in the differential diagnosis.

Sommario Viene presentato il caso di un paziente di 75 anni affetto da un'emicorea secondaria ad una lesione della testa del caudato controlaterale. Gli angiomi cavernosi sono una causa rara di emicorea specialmente nelle persone anziane. Il presente caso però suggerisce che debbano, essere considerati nella diagnosi differenziale dell'emicorea.

     

Ophthalmic herpes zoster with contralateral hemiparesis: a case report

Summary Neurological complications following rubella are only rarely encountered. However, in many cases severe neurological impairment may occur, leading to permanent disability. In a recent epidemic of rubella in Israel during the years 1978–1979, 20 patients with severe neurological complications have been seen. We report on 5 cases of which 3 are described in detail. Considering the efficacy of immunization against rubella, we suggest that in countries such as England and Israel in which periodic epidemics of rubella occur, a generalized plan of immunization should be undertaken during the first years of life. Such an approach will prevent the neurological complication of congenital, as well as acquired, rubella infection.

Zusammenfassung Obwohl neurologische Komplikationen nur selten nach Rubella erscheinen, sind sie in vielen Fällen schwer und können zu permanenten neurologischen Schäden führen. In einer Rubella-Epidemie, die kürzlich in Israel auftrat (1978–1979), wurden 20 Fälle von schweren neurologischen Komplikationen festgestellt. Wir berichten über 5 dieser Fälle, 3 von ihnen in ausführlicher Weise. Nachdem Rubella-Impfung sehr wirksam ist, schlagen wir vor, daß in Ländern wie Israel oder England, in denen Epidemien von Zeit zu Zeit auftreten, ein allgemeiner Impfungsplan für die ersten Lebensjahre eingeführt wird. So ein Plan kann die neurologischen Komplikationen nach kongenitaler oder erworbener Rubella verhindern.
