Lung cancer-related changing profile of B-cell epitopes recognized on mucosal antigens: the Der p1 model.

Background: The natural immunoglobulin G (IgG) response towards antigens presented at the mucosal level in patients with lung cancer, the most frequent mucosal malignancy in humans was studied. Compared with healthy control subjects, patients with lung cancer display lower IgG antibody titers toward antigen p1 of the house dust mite, Dermatophagoides pteronyssinus (Der p1), chronically presented to the respiratory mucosa. The present study further characterizes this defect in terms of antibody specificity.

[Stomatococcus mucilaginosus meningitis in immunocompromised child].

Background: Opportunistic infections are responsible for significant morbidity and mortality in patients with malignancy developing granulocytopenia as a result of therapy. A case of Stomatococcus mucilaginosus meningitis is reported.

Case Report: A 2 year-old boy was admitted because he had developed fever and neutropenia during chemotherapy given for neuroectodermal tumor.

Bactericidal effect and regrowth of Streptococcus faecalis exposed to amoxicillin following beta-lactamase.

Streptococcus faecalis usually requires high concentrations of penicillin or ampicillin to achieve killing (i.e. a high MBC/MIC ratio).

Fatty acid composition of Streptococcus milleri.

The cellular fatty acids of 31 strains belonging to the Streptococcus milleri group were analysed by capillary gas-liquid chromatography. Results were compared with findings from biochemical differentiation of the strains into Streptococcus constellatus (two strains), Streptococcus anginosus (16 strains) and Streptococcus intermedius (13 strains). Eight strains of various other streptococci were included as internal references, including three strains of streptococcus morbillorum, three strains of beta-hemolytic streptococci, and two strains of enterococci.

Malignant Mediterranean spotted fever. Report of a case with multiple organ failure, hypocalcemia, and euthyroid sick syndrome.

A patient with Mediterranean spotted fever presented an initial history of enteritis, pyrexia, and rash. He subsequently developed shock, multiple organ failure, thrombocytopenia, hypocalcemia with hypercalcitoninemia, and a euthyroid sick syndrome.
