[Intravascular malignant B-cell lymphomatosis with renal glomerular involvement: a case].

We report a case of intravascular malignant lymphomatosis observed in a 71 year-old male and characterised by the presence of a proteinuria in relation to the specific intraglomerular localisation. This malignant lymphoma, usually of the B phenotype, is rare and affects predominantly the central nervous system and the skin. Neoplastic cells home selectively to endothelium. Histological renal infiltration is frequent but a glomerular localisation, with proteinuria, is rare. The mechanism whereby lymphocytes home to endothelium cells is unclear but it could be related to the expression of lymphocyte-endothelium adhesion molecules. When present the nephrotic syndrome is associated with minimal change disease.

[Neoplastic pulmonary embolism. An uncommon cause of acute respiratory distress with normal pulmonary radiography].

The incidence of neoplastic pulmonary embolism is certainly underestimated Necroscopy series report figures varying from 2.9 to 26. The clinical manifestations are similar to those observed in cruoric pulmonary embolism. We report two cases of acute respiratory failure with normal chest X-ray in which the diagnosis was neoplastic pulmonary embolism. The difficulties encountered for diagnosis resulted from the diffuse microvascular nature of the lesions. Perfusion scintigraphy and Swan-Ganz catheterism can be contributive, but certain diagnosis requires pathology examination. Prognosis is very poor. Clinicians should be aware of this pathology and entertain the diagnosis in all cor pulmonale patients with acute respiratory failure and a normal chest X-ray.

Acute renal failure following collective intoxication by Cortinarius orellanus.

Twenty-six young men with no previous medical history all ingested mushroom soup, exclusively made with Cortinarius orellanus. They were hospitalized 10-12 days after the incident. On admission, 12 patients presented with acute tubulointerstitial nephritis with acute renal failure; 8 required haemodialysis. In addition to symptomatic treatment, 9 patients were given corticosteroids. In this group of 12 patients, 8 recovered rapidly, and the other 4 suffered from chronic renal failure for several months. In the other group of 14 patients, initial leukocyturia was observed in 12 cases, although renal function remained normal during a one-year follow-up. Hepatic acetylation and hydroxylation tests performed after 6 months in 22 patients did not provide any explanation for the strong individual sensitivity to the renal toxicity of this fungus.

[Adult respiratory distress syndrome, a manifestation of severe pneumococcal infection].

A retrospective study analyzing the case notes of 49 hospitalized adults, either in intensive care (n = 26) or in thoracic medicine units (n = 23), for acute bacteriologically proven pneumococcal pneumonia based on samples obtained other than by sputum examination. The mortality was 54% in intensive care and 17% in the thoracic medicine unit. This significant difference may be explained in part by a respiratory distress syndrome in whom there were adequate criteria on admission for 7 patients in the intensive care group. Among these latter only one patient had had a splenectomy. The others did not have underlying disorders (three were chronic alcoholics); 7 patients were shocked on admission, four with a leukopenia less than 5,000/mm3 and six had a thrombocytopenia less than 100,000/mm3; finally 6 had a temperature of less than 38 degrees C. 7 patients died in less than four days (mean 2 days) in a clinical context of refractory hypoxemia. The significance of the respiratory distress syndrome is probably very different from the usual pneumonia; it seems rather to be an integration of the toxins induced by the pneumococcus. Its presentation can be particularly misleading as regards the diagnosis; the prescription of antibiotics once a diagnosis is obtained would seem insufficient by itself in this context to obtain a cure.

[In vitro effect of antibiotics against hospital strains of Acinetobacter baumanii].

A total of 142 Acinetobacter baumanii strains isolated from hospital patients were biotyped according to the scheme of Bouvet and Grimont. Most of the strains belonged to biotype 9 and were highly resistant to antibiotics including cephalosporins and amikacin. Imipenem and ticarcillin were the only drugs having a bactericidal activity against A. baumanii. The combination imipenem-netilmicin and ticarcillin-netilmicin were more rapidly bactericidal than imipenem or ticarcillin alone. No resistant strain to imipenem was isolated.

[Treatment with a cefotaxime-fosfomycin combination of staphylococcal or enterobacterial meningitis in adults].

Thirty-two patients were included in this trial: 22 with staphylococcal meningitis (including 5 methicillin-resistant) and 10 with enterobacterial meningitis. Mean duration of treatment was 14.5 and 15.9 days respectively. The combination was synergistic in vitro against 10 of the 12 strains of Staphylococcus and 5 of the 6 strains of Enterobacteriaceae studied. Bacteriological sterilization occurred in all cases which could be evaluated, and clinical recovery was obtained in 95.2% of patients with staphylococcal meningitis (4 unrelated deaths) and 100% of patients with enterobacterial meningitis (2 deaths). Bactericidal power of the cerebro-spinal fluid, often less than 1/8, was not correlated with effectiveness against Staphylococci. Mean CSF concentrations of cefotaxime, desacetylcefotaxime and fosfomycin on the 2nd and 15th days of treatment were 4, 3.5 and 39.8 mg/l and 2.2, 2.1 and 28.0 mg/l, respectively. Clinical and biological acceptability was satisfactory. There were three cases of superinfection or colonization, by Pseudomonas and Enterobacter.

Massive hemoptysis from iatrogenic balloon catheter rupture of pulmonary artery: successful early management by balloon tamponade.

Cessation of massive hemoptysis after iatrogenic balloon catheter rupture of the pulmonary artery was observed after a 2-ml inflation of the balloon. A wedge angiogram showed a small cavity near the rupture. Secondary lobectomy was performed; however, the patient died 1 month later. Therapeutic approaches of this life-threatening complication are presented.

[Thrombotic thrombopenic purpura associated with Hodgkin's disease].

We report the second case of Hodgkin's disease associated with thrombotic thrombocytopenic purpura (TTP). Although the two diseases coexisted originally, TTP was diagnosed alone at first. Because of the very rare occurrence of this association the diagnosis of TTP is discussed according to the accepted criteria and taking into account the haematological complications which can reveal or be observed in Hodgkin's disease. No evident relationship between the two diseases can be suggested. But immunologic disorders observed in the two cases suggests that their coexistence is not necessarily accidental. The evolution of these two diseases is particularly good.

[Clinical studies of the erythrocytosis produced by a new hemoglobin with oxygen affinity : Hb Hôtel-Dieu alpha 2A beta 2 Asp replaced by Gly (author's transl)].

A new case of erythrocytosis associated with a high oxygen affinity hemoglobin is reported : the substitution of beta 99 of aspartic acid by glycine, characterized this abnormal hemoglobin, named "hemoglobin Hôtel-Dieu". An important associated smoking habit, probably responsible of an abnormal lung X-ray and of a disturbed CO transport, contributed to increase the difficulty of diagnosis. Familial inquiry, the search of an abnormal hemoglobin by standard or isoelectrofocusing electrophoresis, and the 2,3-DPG assay should be systematically performed in case of polycythemia in young people or in the absence of obvious aetiology. A corpuscular abnormality can be thus detected in about 10 p. cent of such polycythemias.

[Polycythemia resulting from abnormal hemoglobin with increased affinity for oxygen. Two cases (author's transl)].

An abnormal hemoglobin with increased oxygen affinity has to be suspected in all the cases of polycythemia where no direct signs of "polycythemia vera", or any of the classical reasons for erythropoietic stimulation can be demonstrated. This fact is documented by two new observations, one concerning a 44 year-old man with Hb Kempsey, another concerning a 58 year-old woman with Hb Malmö. The diagnosis is based on a scrupulous electrophoretic study involving an isoelectric focusing on polyacrylamide gel, and, on the study of the oxygen binding properties of the red blood cells. This polycythemia being a compensatory mechanism allowing a normal oxygen delivery to the tissues has to be respected and a compromise must be found with the cardiovascular risk.

[Migraine or transient ischemic attacks in a patient with essential thrombocythaemia. Treatment with ticlopidine (author's transl)].

Ischemic cerebrovascular symptoms occuring in patients with essential thrombocythaemia are usually attributed to platelet or platelet-fibrin emboli. A patient is described in whom transient ischemic attacks (TIA) had some features - namely the presence of headache and the progressive onset of symptoms - unusual for an embolic phenomenon but suggestive of a migrainous event. No further attack occured when the patient was treated by an antiplatelet drug ticlopidine, though platelet count was unchanged. The relationship between platelets, TIA and migraine are discussed.

[Increased hematological toxicity of antineoplastic drugs with simultaneous androgenotherapy (author's transl)].

Thirty two patients with malignant lymphoma - mainly Hodgkin's disease - were randomized for simultaneous treatment by high doses of metenolone during MOPP chemotherapy, to reduce its hematological toxicity. The results have shown surprisingly an increased hemato-toxicity in patients receiving androgens, with significantly more marked anemia and thrombocytopenia, reducing the total doses of anti-cancer drugs. This side effect could be explained by a cycling of the hematopoietic stem-cells and call to some caution when androgens are used during cancer chemotherapy.

Cell volume measurements in acute leukaemia: method and value for diagnosis and prognosis.

Cell volume was measured using a Coulter counter in 42 cases of adult acute leukaemia, before any therapy. In every patient, the distribution was log-normal. A breakdown of the results with regard to the cell-type gives the following informations: The mean modal volume (M.M.V.) differs significantly from one type of leukaemia to another: the cell size in the myeloblastic type is larger than in the lymphoblastic, and smaller than in the monoblastic and myelomonocytic types. The dispersion of cell volumes, for a single patient, is low in acute lymphoblastic leukaemia, wider in myeloblastic cases and is even larger in myelo-monocytic patients. In 9 of the 10 acute myelo-monocytic leukaemias studied, the existence of two populations was shown by a double peak. Once relapse occurs, the cell volumes seem greater than during the first phase of the disease, at least in acute lymphoblastic leukaemia. No correlation has been found between the mean modal volumes and the labeling index, after incorporation of 3H-TdR.
