The authors report their experience of 21 revision operations for malfunction of the Beall Surgitool 104 prosthesis used in the mitral position. The incidence and uniformity of the disorders found in the prostheses suggest that these changes are produced inevitably usually during the fourth year. The disc becomes kinked, the mountings eroded, and the teflon ring torn. The clinical features are the onset of heart failure, anaemia, or a thrombo-embolic episode. These three findings may occur individually or in association. The authors do not advise systematic revision surgery, but conclude that close follow-up is essential in the case of all patients who have had a Beall prosthesis. Early signs of failure should be revealed by clinical examination, the level of LDH, and by phonocardiogram and echocardiogram studies. Leaving aside thrombo-embolic episodes and severe anaemia which themselves constitute indications for revision surgery, the decision to replace the damaged prosthesis should be taken as soon as the first signs of cardiac failure are detected.

Eighty-eight patients with hormone-resistant Stage IV prostate cancer were treated with a five-drug chemotherapy program. Patient demographic data, prior therapy, symptoms, extent of disease, and laboratory studies were analyzed statistically to evaluate the association of these parameters with survival from the onset of chemotherapy. Factors associated with short survival included age greater than 65, severe bone pain, poor performance status, presence of soft tissue metastases, anemia, elevation of serum LDH, SGOT, alkaline and acid phosphatases, and prolactin, and hypoalbuminemia. Race, stage at initial diagnosis, prior radiation therapy, prior orchiectomy, and elevation of CEA had no prognostic association. We suggest that clinical trials of new therapies of hormone-resistant prostate cancer take into account the presence of these prognostic factors in the analysis of the results of therapeutic programs.

A 16-year-old girl with myocarditis and hepatitis in the course of mycoplasma pneumoniae infection was reported. She had fever and coughed for ten days prior to admission. At the time of admission infiltrations of the left lower lung field were revealed on the chest X-ray films. The ESR was elevated and CRP+6. There were no leukocytosis and anemia, but S-GOT, S-GPT and LDH were moderately increased. On the 11th day of admission VPC in bigeminy appeared and the third sound was heard. Subsequently biphastic and inverted T waves in leads V2 and V3 and flattening of T waves in leads II and aVF appeared. At the same time, the cardiac shadow was enlarged. Antibody titer to mycoplasma pneumoniae increased to more than 1:640 two weeks after admission and then it decreased gradually. The cold agglutinin test was 1:64 on the 8th day of the disease and then it became normal. ASO, antibodies to DNA and immunoglobulins were normal; ANA, Coombs test and LE test were negative. The abnormal ECG-findings were normalized three months later.

Several haematological findings (especially the values of serum LDH and its isoenzymes) were compared with changes in the gastrin level in pernicious anaemia. While vitamin B12 substitution therapy led to normalization of the anaemia and of the enzyme levels, gastric atrophy and, hence, the elevation in serum gastrin levels remained unchanged. Determination of serum gastrin, therefore, provides a valuable tool for the verification of the diagnosis of pernicious anaemia in treated cases.

A description is given of an outbreak of equine infectious anaemia (E.I.A.) in Campania [at Naples and Aversa (Caserta)]; it was diagnosed by clinical, pathological and serological examinations (Coggins test). Using the serum of 45 horses with E.I.A. and 11 healthy horses (controls), numerous investigations were carried out on: enzymes, intrinsic coagulation factors, lipids and other substances. The results obtained were very interesting and show that in this disease there are significant increases in many enzymes (LDH, LAP, gamma-GT, CPK, PK and ALD) and copper. Insignificant increases were found in other enzymes (SDH, GLDH, MDH, ICDH, AIP, lysozyme, cholinesterase, GOT and GPT) and also intrinsic coagulation factors, lipid substances (total cholesterol, esterified cholesterol, triglycerides) and glucose. LDH-1-isoenzyme remains unchanged, whilst AcP decreases slightly.

Hematograms, platelet function, and blood-enzyme chemistry were compared in two similar saturation-excursion dives, one conducted in a hyperbaric chamber and the other in the open sea. The chamber dive was more stressful in that it was preceded by a series of bounce decompression dives (one of which produced a 100% incidence of cutaneous pruritus in four subjects) and in that the excursions from saturation depth (60 fsw or 2.818 ATA) were longer and deeper (producing one case of O2 convulsions, one of confirmed decompression sickness, and several of Doppler-detected vascular bubbles). The chamber dive was associated with a marked and significant reduction in circulating platelet count; significant increases in plasma enzyme activities in the victim of O2 toxicity (LDH, CPK) and in one subject with Doppler bubbles and questionable bends symptoms (LDH, GOT, GPT) but not in another; and mild but significant anemia. In the open-water dive, one subject, who developed symptoms of gastroenteritis, showed moderate elevation of LDH, GOT, and GPT activity. No significant change in platelet counts occurred. Both dives were associated with elevated white-cell counts, apparently as a result of numerous minor infections, and reduced sensitivity of platelets of ADP-induced aggregation.

A case of B cell lymphoma with clinical and histological features of malignant histiocytosis was described. A 57-year-old male was admitted to Shinshu University Hospital because of transverse myelopathy. Five months before admission, he noticed urinary disturbance, which progressed to urinary obstruction. The following month, bilateral muscular weakness appeared in his legs. A few days later he could not stand up, and was admitted to a local hospital. Neurological examination revealed sensory disturbances below the level of Th12 in all modalities, and marked weakness and hyperreflexia in the lower limbs. A spinal tumor was suspected. However, myelography showed no abnormality. The patient's condition worsened and he became bed-ridden in February 1990. He was transferred to Shinshu University Hospital for further evaluation. On admission he was poorly nourished with fever, anemia, hepatomegaly, and bilateral pretibial pitting edema. No lymphadenopathy was observed. Neurological examination showed total sensory loss below the level of Th12, spastic paraplegia, hyperreflexia in the legs, and urinary obstruction. Laboratory findings revealed an elevated erythrocyte sedimentation rate, increased CRP, pancytopenia, and hypoalbuminemia. Serum level of IgG, IgA, IgM, LDH, ALP, GPT and total bilirubin were increased. CSF and MRI imaging of the spinal cord were normal. Proliferation of atypical histiocytes with marked erythrophagocytosis, which is a characteristic pathological feature of malignant histiocytosis, was observed in peripheral blood and aspirated bone marrow. Immunoenzyme staining of bone marrow using monoclonal antibody L-26, which is a B-cell marker, revealed B-cell lymphoma.(ABSTRACT TRUNCATED AT 250 WORDS)

A case of thrombotic thrombocytopenic purpura (TTP) which was successfully treated by slow infusion of vincristine (VCR) is reported. A 40-year-old female was admitted to our hospital because of sudden onset of genital bleeding. Her blood cell count showed severe anemia and thrombocytopenia. Biochemistry disclosed high titers of serum LDH. Based upon these findings, the patient was initially diagnosed as having Evans syndrome and was treated with steroid-pulse therapy and high-dose immunoglobulin. However, no response was obtained. A diagnosis of TTP was established when mental disturbance and renal dysfunction developed later. Aspirin and plasmapheresis relieved the mental disturbance and decreased serum LDH level, but anemia and thrombocytopenia were not corrected. Slow infusion therapy of 1 to 2 mg VCR was performed for 4 to 8 hours once a week, which dramatically improved the hematological abnormalities and controlled the disease. In conclusion, slow infusion of VCR may indicated, if initial standard therapies such as PE would fail.

The clinic-epidemiologic and prognostic features of 424 cases of Ewing sarcoma observed at "Rizzoli" Institute between 1972-1990 are reported. The incidence of the tumor was higher in the second decade of life with slight predominance in the male sex. The primary lesion was especially localized in the extremity and the ratio lower/upper extremity was 5/1. We did not find, in contrast with other Authors, differences in height or in incidence of congenital malformations when compared to controls. The pain was the first common symptom at debut (90%) followed by swelling (50%) and fever (40%). Diagnosis was made 5.5 months after the first symptom and the delay was due to wrong diagnosis at debut in 3/4 of the patients. Laboratory tests showed anemia in about half of the patients and increased value of ESR (60%) and LDH (40%). Seventy-one of the patients were metastatic at presentation, none of these patients were still living after three years. At a median follow-up of 9 years 43% of the patients with localized disease, treated with adjuvant and neo-adjuvant chemotherapy remained continuously disease free, 53% developed metastatic disease and/or local recurrences and 2% had a second malignancy. In 24% of the patients metastases and/or local recurrences appeared three years after the beginning of treatment. Better prognosis was observed in female patients, without fever at diagnosis, with tumor localized at extremities and with normal value of hemoglobin, ERS and LDH. Regarding the type of treatment, better results were obtained by surgery of the primary tumor and by chemotherapy with four drugs (vincristine, cyclophosphamide, adriamycin dactinomycin) in comparison to radiotherapy of the primary tumor and chemotherapy with three drugs (vincristine, cyclophosphamide, adriamycin).

Hemolysis can be induced by two general mechanisms. In the first one, erythrocytes lyse intravascularly due to complement fixation, trauma, or other extrinsic factors. In the second mechanism, which is the most common, the red cells are removed from the circulation by the mononuclear-phagocytic system either because they are intrinsically defective or because of the presence of bound immunoglobulins to their surfaces. The diagnosis of hemolysis is not difficult to establish and is based on the presence of anemia with sustained reticulocytosis in the absence of blood loss. Additional findings can include marrow erythroid hyperplasia; increased unconjugated bilirubin, LDH, and free hemoglobin; decreased haptoglobin and hemopexin; hemoglobinuria and hemosiderinuria; and decreased 51Cr red cell half-life. Hemoglobinemia, hemoglobinuria, and hemosiderinuria occur only in the setting of severe and rapid intravascular hemolysis. Conditions associated with significant lysis of red cells in the circulation include incompatible transfusion, G6PD deficiency, PNH, severe burns, and certain infections. The morphology of the red cell is abnormal in almost all cases of hemolytic anemia. However, the morphologic abnormality can be, in certain cases, diagnostic of the underlying condition. Treatment is usually supportive, with effective therapy directed to treat the underlying cause of hemolysis.
