Identifying potential kidney donors among newborns undergoing circulatory determination of death.

Background: Over 96,000 patients await kidney transplantation in the United States, and 35,000 more are wait-listed annually. The demand for donor kidneys far outweighs supply, resulting in significant waiting list morbidity and mortality. We sought to identify potential kidney donors among newborns because en bloc kidney transplantation donation after circulatory determination of death (DCDD) may broaden the donor pool.

Identifying potential heart donors among newborns undergoing circulatory determination of death.

Background: Infants younger than 1 year old have the highest heart transplant wait-list mortality. Transplantation from donors after circulatory determination of death (DCDD) is an innovative new option for these patients. We examined the potential for heart donation in neonatal intensive care unit (NICU) patients undergoing elective withdrawal of life support.

Digital tomosynthesis in breast imaging.

Purpose: To describe and evaluate a method of tomosynthesis breast imaging with a full-field digital mammographic system.

Materials And Methods: In this tomosynthesis method, low-radiation-dose images were acquired as the x-ray source was moved in an arc above the stationary breast and digital detector. A step-and-expose method of imaging was used.

Philosophies and principles of removable partial overdentures.

Retention of remaining teeth for use as overdenture abutments has been widely used in the discipline of complete denture therapy, but has frequently been overlooked as a means of enhancing removable partial denture therapy. There are considerable advantages in retaining even severely compromised teeth that can be included in a treatment plan for providing removable partial overdentures. The value of such teeth in providing aesthetic improvement, residual bone retention, denture base support, primary or secondary retention, and improved stability should be of primary importance in treatment planning.

Mosquito control in wastewater: a controlled and quantitative comparison of pupfish (Cyprinodon nevadensis amargosae), mosquitofish (Gambusia affinis) and guppies (Poecilia reticulata) in Sago pondweed marshes.

We compared the abilities of pupfish, mosquitofish and guppies to control mosquitoes in wastewater marshes. All species of fish reduced mosquito emergence. When fish population densities were similar, fish reduced emergence to similar levels.
