Hemolytic anemia and thrombocytopenia induced by cyanidanol.

Five patients who received cyanidanol for 4-36 months are presented. Three developed both hemolytic anemia and thrombocytopenia, while 2 had only thrombocytopenia. After suspending the drug the hematological values returned to normal in all of the patients. Drug-dependent platelet antibodies were detected in 4 of the 5 patients and cyanidanol-dependent red blood cell antibodies were present in 3. There are various mechanisms involved in the cyanidanol-induced immune cytopenias and, as in the present study, were sometimes simultaneously observed in the same patient.

A metastatic breast carcinoma presenting as autoimmune hemolytic anemia.

The authors describe the case of a 75-year-old female who was hospitalized for anemia of unknown origin. Physical examination revealed a swelling in the right mammary region, where a mastectomy scar was present from surgery for a breast carcinoma. On admission, laboratory tests disclosed anemia (Hb, 8.5 g/dl), with a reticulocyte count of 65,000/mm3 and slightly increased bilirubin. Immunohematologic study revealed the presence of a red cell autoantibody with anti-D specificity in the serum and in the eluate from the patient's erythrocytes. A biopsy of the swelling was performed and histologic examination showed the presence of metastatic cells of breast carcinoma. The patient was given chemotherapy and radiotherapy. At this writing the anemia was absent, the immunohematologic study was negative, the swelling was greatly reduced, and no other metastatic lesions of breast carcinoma were present.

Prognostic value of autoantibodies against erythrocytes and platelets in chronic lymphocytic leukemia (CLL).

Antiglobulin test (AT) and Dixon tests were performed in 100 patients with CLL. Thirty-five of them had Rai stages 0 or 1, 19 stage 2, 13 stage 3, and 33 stage 4. Twelve patients showed red blood cells autoantibodies (RBCAb) positivity; positivity at Dixon test (direct, indirect, or both) was observed in 74%. The presence of autoantibodies against erythrocytes and platelets did not influence survival curves, but anemia and thrombocytopenia are considered risk factors, independently of the presence of an autoimmune disorder. Nine RBCAb positive patients with positive Dixon test had the worst survival curves, 5 of these were anemic and 1 thrombocytopenic and anemic.

[Spontaneous regression of lumbar disk hernia].

Four cases of spontaneous regression of herniated nucleus polposus are described, which were followed after conservative medical treatment. Three female and one male patients who suffered from severe lumbago were evaluated; their age ranged 24-59 years. From the first CT scan on which herniation was diagnosed to follow-up control after complete regression of symptoms an average period of 14 months elapsed. Comparing ours with literature data, a substantial agreement was observed of both timing of spontaneous regression and location (most often involved was the last lumbar intervertebral space). The age of one of our patients (59 years) is to be stressed, which is well above the mean age reported in literature (35 years). The pathogenesis of regression is still unknown. The most reliable hypothesis seems to be that of dehydration and progressive atrophy of the herniated nucleus polposus. The appearance, in some cases, of the vacuum disk phenomenon seems to support such a thesis. Therefore, the diagnosis of a herniated nucleus polposus of relatively small size, still contained in an intact posterior longitudinal ligament, widely justifies the choice of waiting tactics.

Incidence and prognostic significance of autoantibodies against erythrocytes and platelets in chronic lymphocytic leukemia (CLL).

Antiglobulin Test (AT), and Dixon Tests (DT) have been studied in 100 patients with CLL. Thirty-five patients were Rai stage 0 and I, 19 patients stage 2, 13 patients stage 3 and 33 patients stage 4. Twelve patients showed a Red Blood Cells Autoantibodies (RBCAb) positivity; a positivity (direct, indirect, or both) of DT was present in 74% of patients. The presence of autoantibodies against erythrocytes and platelets did not influence survival curves, but anemia and thrombocytopenia are risk factors for survival, independently of the presence of an autoimmune disorder. Nine patients RBCAb positive and DT positive showed the worst survival curve, five out of these were anemic and one thrombocytopenic and anemic.

[Computerized tomography in acetabular fractures].

The paper deals with sixteen cases of acetabular fractures studied with CT. After a short description of the normal CT findings, the different kind of fractures are reported. The usefulness of CT examination in evaluating acetabular fractures and their complications is confirmed both in conservative treatment and surgical approach.

Evans' syndrome in paroxysmal nocturnal hemoglobinuria.

We describe the first case of paroxysmal nocturnal hemoglobinuria with Evans' syndrome. The immunohematological studies of this patient, a 27-year-old man, revealed the presence of red cell and platelet autoantibodies, related to an episode of anemia and thrombocytopenia.

Mycoplasma pneumoniae infection complicated by paroxysmal cold hemoglobinuria with anti-P specificity of biphasic hemolysin.

A 7-year-old boy with Mycoplasma Pneumoniae infection complicated by transitory paroxysmal cold haemoglobinuria (PCH) is described. The Donath-Landsteiner-antibody exhibited anti-P specificity; hemolytic activity was partially inhibited against papainized erythrocytes at 0 degrees C incubation temperature and increased from 8 degrees C upwards. The association of Mycoplasma pneumoniae infection with PCH has been described 4 times only and in one instance where specificity was stated it was anti-I.

Cold-haemagglutinin disease with an autoantibody exhibiting different specificities at different temperatures.

A case of chronic cold-haemagglutinin disease is reported in which an agglutinin apparently carrying two specificities was present. At first, specificity was anti-not-I and anti-I respectively: in the course of time anti-I was replaced by anti-A-1. Both anti-I and anti-A-1 could be demonstrated at room temperature only while specificity was anti-not-I at 4 degrees C. The antibody displayed haemolytic activity at room temperature and gave stronger reactions when treated biphasically. The same pattern of specificity was apparent in haemolysis tests, i.e. anti-not-I in the biphasical reaction 4 degrees C goes to 37 degrees C and first anti-I and later anti-A-1 at room temperature and at 22 degrees C goes to 37 degrees C. Anti-A-1 was not neutralized by A bloodgroup substance of animal origin nor by secretor saliva.
