    Notes: Abstract Surgical excision is considered the treatment of choice for cystic hygromas (CH). However, radical surgery may result in serious complications, and nerve palsy due to dissection occurs in 12% – 33% of cases in most series. Resection is especially difficult and sometimes impossible if the lesion involves the floor of the mouth, tongue, and larynx. Different alternative treatment modalities have been advocated in cases of life-threatening, unresectable CHs, however, most of them are associated with severe side effects and doubtful effectiveness. Two children with inoperable CHs of the head and neck are presented. Since intralesional injection of sclerosing agents was unsuccessful, they were treated with IV cyclophosphamide. In both patients tumor size markedly regressed and vital functions stabilized, even though only partial remission was obtained. Cyclophosphamide seems to be a useful and well-tolerated treatment alternative in children with unresectable life-threatening CHs.

    Notes: Abstract In the present study we investigated the long-term effect of intravenous pulse cyclophosphamide (CY) on lymphocyte surface antigens in systemic lupus erythematosus (SLE) patients. Blood samples derived from 17 lupus erythematosus patients were analysed using two- and three-colour flow cytometry. During the CY therapy, the total number of T lymphocytes (CD3+) was reduced by 31.4%, B lymphocytes (CD19+) by 67.4% and NK cells (CD16+) by 27.4%. Six months after the end of the CY regimen, these values recovered to entry levels. At the onset of the study we observed increased percentages of CD3+ CD25+, CD3+ CD4– CD8–, CD4+ CD29+, CD19+ and CD19+ CD5+ cells. The CY treatment regimen decreased the CD3+ CD25+, CD3+ CD4– CD8–, CD19+ and CD19+ CD5+ cells, but increased the CD3+ CD8+ subpopulation. Taken together, a deficiency of CD8+ T cells associated with CD4+ CD29+ predominance may imply an immune regulatory imbalance leading to abnormal CD4+ cell activation and in consequence to autoimmunity. Depletion of CD19+ cells combined with an enlargement of CD8 cells as a result of CY therapy may reduce the enhanced immune response in SLE patients.
