Cryoglobulinaemia in a patient with Proteus mirabilis sepsis.

Mixed polyclonal cryoglobulinaemia was evidenced in a 49-year-old woman admitted to our hospital because of Proteus mirabilis sepsis associated with polyarthralgia and purpuric manifestations on the lower limbs. Cryoglobulins and circulating immune complexes decreased during the second week of illness and disappeared after recovery. CH50, C3 and properdin factor B, which were low during the early phase of the illness, returned to normal; C4 was normal throughout. The rapid clearance of cryoglobulins and immune complexes and the restoration of a normal complement profile might all be explained by the gradual elimination of P. mirabilis due to chemotherapeutic treatment.

The GABAergic control of prolactin release is not affected by insulin-dependent diabetes mellitus: evidence from studies with sodium valproate.

In order to evaluate the influence of the GABAergic system in the regulation of PRL secretion in patients with IDDM, serum PRL levels were measured in 7 diabetics and in 7 normal men with sodium valproate (400 mg per os), a drug capable of increasing cerebral GABA concentrations. A significant decrease of serum PRL concentrations was observed between 30 and 120 min after sodium valproate administration in both control and diabetic subjects. The time course and magnitude of the sodium valproate effect were similar in all subjects. These data confirm the inhibitory control of the GABAergic system on PRL secretion in man as evidenced by the GABAergic drug sodium valproate. It is suggested that this system is not altered in diabetic patients.

Chronic neutrophilic leukemia (CNL) with karyotypic abnormalities associated with plasma cell dyscrasia: a case report.

A case of chronic neutrophilic leukemia (CNL), a rare myeloproliferative syndrome associated with monoclonal gammopathy of uncertain significance (MGUS-Type IgGk), is reported. Karyotypic study, carried out on bone marrow, excluded Philadelphia-pos. chronic myeloid leukemia (CML) and showed Y loss (45 XO). Only a few cases of CNL with paraproteinemia have been reported, but no case of associated karyotypic abnormalities and paraproteinemia has so far been described.

[Microbiological characterization of solid wastes and aerosol in a municipal solid waste landfill site].

Authors report data about microbiological characterization of solid wastes and aerosol in the municipal solid waste landfill site in Poiatica (RE). In solid waste samples high values of total coliform and fecal coliform were observed (10(5)-10(6) CFU/g): total bacterial counts at 22 degrees, at 36 degrees and at 44 degrees ranged from 10(7) to 10(9) CFU/g. Aerosol samples collected during waste movement in the landfill site showed values of total and fecal bacterial ranging from 10(3)-10(4) CFU/m3. Staphylococci and fungi reported the same values while streptococci, total and fecal coliform and spore evidenced lower values. Municipal solid wastes and aerosol have to be considered as an infective substrate: it is necessary to adopt protective barriers in occupationally exposed subjects.

Mucinous cystadenoma of the pancreas as a cause of acute pancreatitis.

Acute pancreatitis is only rarely the first presentation of a cystic neoplasm of the pancreas. Mucinous cystadenomas have not been reported to be a cause of acute pancreatitis; however, we present two cases of mucinous cystadenoma of the pancreas which have caused acute pancreatitis. Both patients (female) presented acute abdominal pain, with serum amylase elevation and ultrasound scan (US) and computed tomography (CT) evidence of moderate pancreatitis, which resolved with medical treatment; fluid collection in the distal pancreas had been misinterpreted as a pseudocyst. There was no history of alcohol abuse or gallstone disease. After distal pancreatectomy the diagnosis of mucinous cystadenoma was confirmed; in one case a large pseudocyst was associated with this diagnosis. Pre-operative differential diagnosis between inflammatory and neoplastic cysts is difficult, especially when the patient's first presentation is due to an episode of acute pancreatitis. A neoplastic cyst should be considered when acute pancreatitis attacks occur in non-alcoholic women, who do not have gallstone disease.
