Evaluation of the bacterial burden of gel nails, standard nail polish, and natural nails on the hands of health care workers.

BACKGROUND: Acrylic nails harbor more bacteria than natural nails, and wear is not recommended for health care workers (HCWs). Little is known about the new and popular gel nail products. This study sought to evaluate the bacterial burden of gel nails, standard nail polish, and natural nails on the hands of HCWs. METHODS: The study was conducted at 3 health centers. Nails on the dominant hand of 88 HCWs were painted with gel polish and standard polish. Cultures were obtained on days 1, 7, and 14 of wear and before and after hand hygiene with alcohol hand gel. RESULTS: A total of 741 cultures were obtained. Bacterial burden increased over time for all nail types (P ≤ .0001). Reductions in the bacterial burden of natural nails and standard polish, but not gel polish, (P = .001, P = .0028, and P = .98, respectively) were seen after hand hygiene. All 3 nail types become more contaminated with bacteria over time. Standard polish and natural nails may be more amenable to hand hygiene than gel polish. CONCLUSIONS: This study did not show an increased number of microorganisms on nails with gel polish; however, gel nails may be more difficult to clean using alcohol hand gel.

Activity of single-agent decitabine in atypical chronic myeloid leukemia.

Atypical chronic myeloid leukemia is a rare entity that presents diagnostic and therapeutic challenges. Traditionally utilized therapeutic agents such as hydroxyurea or interferon result in a median survival of approximately two years, thus warranting identification of better options. We report a 49-year-old Caucasian female, who presented with extreme leukocytosis (white blood cells of 148,300/µL) with left shift, severe anemia, and thrombocytopenia. Following a diagnosis of atypical chronic myeloid leukemia, she was started on intravenous decitabine. She subsequently developed paraneoplastic vasculitis of large arteries, which responded to high-dose glucocorticoid. Decitabine therapy resulted in an excellent hematologic response, transfusion independence, and successful transition to an allogeneic peripheral stem cell transplantation. However, the patient subsequently succumbed to the complications of acute graft-versus-host-disease. This case illustrates an association between atypical chronic myeloid leukemia and steroid-responsive paraneoplastic vasculitis and highlights the single-agent disease activity of decitabine in atypical chronic myeloid leukemia, which may be utilized as a bridging therapy to allogeneic stem cell transplantation.
