Recombinant human granulocyte colony-stimulating factor administration in a case of neutropenia due to increased neutrophil sequestration.

A 55-year-old female was admitted with fever which followed an episode of pseudomembranous colitis. Despite an accurate clinical investigation, there was no evidence for specific sites of infection. Remission of fever was not obtained with antibiotic therapy (gentamycin plus carbepenem) and progressive neutropenia was observed.

Expansion of TcRalphabeta+CD3+CD4-CD8- (CD4/CD8 double-negative) T lymphocytes in a case of staphylococcal toxic shock syndrome.

A 55-year-old woman presented with staphylococcal toxic shock syndrome (TSS). During the course of the disease a significant lymphocytosis appeared, and a high number of TcRalphabeta+CD3+CD4-CD8- (double-negative, DN) lymphocytes was observed both in bone marrow and in peripheral blood samples. Correction of the altered lymphocyte immunophenotype was observed only 6 weeks after recovery from TSS.

Gas monitoring and uptake.

The breath-by-breath monitoring of anesthetic gases can provide information, beyond the usual safety control. The study of the decay and concentration effects along the circuit can be useful to evaluate their kinetics. The presence of unexpected gases coming from the patient's tissues is another important topic.
