[Noma in a patient with acute leukemia allergic to penicillin].

Noma has virtually disappeared from Europe, but is still found in certain parts of Africa, South America and Asia. In our case the etiologic agent was Pseudomonas aeruginosa sensitive to antibiotic therapy that we used (pefloxacin and netilmicin). Another characteristic aspect of our case is the rapid infaust evolution. In this report will be discuss the pathogenesis and the reason of the failure of the antibiotic therapy especially in immunodeficiency patients.

[The onset of double metachronous neoplasms 29 years after the diagnosis of Hodgkin's disease].

The occurrence of two new cancers (a diffuse centrocytic lymphoma and a basal cell cancer) in a patient successfully treated for Hodgkin's disease 29 years before is reported. The centrocytic lymphoma mainly involved the skin, the basal cell carcinoma developed on the dorsum of the right hand. The patient had received high-dose Roentgen-radiation therapy on the mediastinum and lymph nodes for his Hodgkin's disease. The possible relationship between performed therapy and occurrence of new malignancies is discussed.

Platelet alpha-granule release in chronic myeloproliferative disorders with thrombocytosis.

Platelet alpha-granule release in 22 patients affected by chronic myeloproliferative disorders with thrombocytosis and seven subjects with thrombocytosis secondary to splenectomy were studied. We found elevated beta-thromboglobulin (BTG) and platelet factor 4 (PF4) plasma levels in all patients. Intraplatelet content of BTG and PF4 was decreased in patients with idiopathic thrombocythaemia (IT) and idiopathic myelofibrosis (IMF). The BTG and PF4 results were also expressed as the ratio plasma BTG and PF4: whole blood platelet count. In patients with IT, BTG: whole blood platelet count ratio was low, conversely, the same ratio was high in patients with IMF. In conclusion, our results suggest the presence of an abnormal, BTG-deficient clone in IT and a peripheral platelet activation in IMF.

Platelet alpha granule release in diabetes mellitus.

We studied beta-thromboglobulin (BTG) and platelet factor 4 (PF4) plasma levels in 90 diabetic subjects; we found high plasma values of these proteins only in patients with complications. To provide further indications regarding the role of platelet activation in the pathogenesis of diabetic microangiopathy, we also tested mobilizable platelet content of BTG and PF4; we found these similar to those of normal subjects.

[Hematologic changes in renal neoplasms].

The main haematological parameters, particularly haemoglobin concentration and the numbers of leukocytes and platelets, were studied in 146 kidney tumour patients. Only 119 of the subjects studied later underwent nephrectomy. In 66 patients the tumours were limited to within the renal capsule (group I) while in 39 other subjects the tumours had gone beyond this limit and had invaded the perirenal tissue (group II). 27 patients had metastasis in one or more sites (group III). In the remaining 14 subjects (group IV) without proven metastasis, the surgical staging was not available since because of cachexia they were not undergone nephrectomy. More frequent signs were: anaemia (Hb less than 12 g/dl), mainly normochromic, found in a high percentage of cases (41% in group I, 59% in group II, 74% in group III, 79% in group IV); leukocytosis (G.B. greater than 8000/mm3: 38% in group I, 51% in group II, 37% in group III, 50% in group IV). Mild thrombocytosis (P = 350-500 X 10(3)/mm3) was found with notable frequency mainly in groups II and III (20% and 18% respectively). On the other hand leukopenia (G.B. less than 3500 per mm3) and thrombocytopenia (P less than 140 X 10(3) per mm3) were rather rare. The results of our study are also discussed in relation to the main findings in the literature.

[Hematological complications of viral hepatitis. Case-list contribution].

The incidence of haematological abnormalities has been evaluated in 1170 patients affected by acute viral hepatitis. Of these patients, 665 were HBsAg+, 427 HBsAg-, 31 with IgM anti-HAV, 26 non A and non B hepatitis. 21 patients were not classified due to lack of data relating to markers for HAV or HBV. Anemia, leucopenia, thrombocytopenia and pancytopenia were found with some frequency at the haemochromocytometric examination. It is emphasized that these haematological abnormalities are often of minor relevance whereas the rarer and more serious complications such as persistent bone marrow hypoplasia or pure aplastic anemia can present difficult clinical problems regarding prognosis and therapy: in 4 cases of bone marrow hypoplasia a recovery was obtained in 1 case only, whereas the remaining cases had a fatal outcome after a period varying from 20 days to 15 months from the appearance of pancytopenia. We suggest the advisability of a closer study of the haematological and immunological aspects in patients with viral hepatitis in order to discover those elements which are useful towards a better understanding of the etiopathogenesis of the haematological abnormalities studied above. Such a detailed study would also enable further improvement in existing therapeutic measures.

Clearance of viable Calmette-Guèrin bacillus by the in vitro isolated and perfused rat liver.

Liver efficiency in clearing circulating BCG (Clamette-Guèrin bacillus) was studied using the isolated rat liver. Bacteria were added to the perfusate at a concentration of 1 X 10(6) cells/ml, and the medium was then sampled at subsequent intervals for 6 hours in 2 perfusions and for 1 hour in 7 perfusions. At the end of all perfusions, liver and bile samples were obtained and used for viable bacterial counts. For each perfusion the bactericidal activity which might have been exerted by serum present in the perfusate was also investigated. About 95% of BCG disappeared from the perfusate after 6 hours of perfusions, and 90% after 1 hour. Recovery of viable bacteria in the liver at 60 minutes averaged 80% of the inoculum. Recovery in bile was negligible. Control experiments indicated that extrahepatic factors in possible reduction of bacterial concentration in the perfusate did not interfere with hepatic removal, per se.
