ABSTRACT. Contemporary medical practice in the NICU sometimes leads to conflicts between providers and parents in which the parent demands continuation of life-sustaining treatment that the medical team deems medically inappropriate or futile. Such conflicts can be difficult to resolve and trying for all parties. Here we describe a conflict involving a 25-week-gestation, 825-g newborn with multiple intractable medical problems and resolution of the conflict through ethics consultation under provisions of the Texas Advance Directives Act. The process established under Texas law sets conceptual and temporal boundaries around the problem of medical futility and provides a legal safe harbor for physicians who seek to withdraw life-sustaining treatments in the setting of medical futility, allowing resolution of such conflicts in a timely and effective manner. As such, it may provide a model for physicians in other states to follow. Pediatrics 2005; 116: 12191222; conflict resolution, end of life, ethics, intensive care, futility, for example, fda.

Together, these data suggest that, in vivo at concentrations achievable in patients, leflunomide inhibits de novo pyrimidine synthesis in activated lymphocytes and other rapidly dividing cell populations resulting in reversible cell cycle arrest and hydroxyzine. Because of compelling data linking STD acquisition and HIV transmission, early detection and appropriate treatment of STDs are considered key components of a comprehensive strategy for HIV prevention 8 ; . Among persons with STDs, those with ulcerative STDs typically have a higher prevalence of HIV co-infection, reflecting the fact that ulcerative STDs and HIV infection have shared risk factors and strong mutually reinforcing effects: Ulcerative STDs can increase HIV transmissibility, and HIV infection can cause ulcer persistence 4 ; . Several recent advances have been made in the management and treatment of genital ulcer disease. In the United States, most sexually active persons with genital ulcers have genital herpes, syphilis, or chancroid 9 ; . However, diagnosis of these conditions on the basis of medical history and physical examination is often inaccurate unless accompanied by specific diagnostic testing 10 ; . Therefore, evaluation of all patients with genital ulcers should include a serologic test for syphilis and a diagnostic evaluation for genital herpes; in settings where chancroid is prevalent, a test for Haemophilus ducreyi should be done. Biopsy of ulcers may help identify the cause of unusual ulcers or ulcers that do not respond to initial therapy. Testing for, for example, leflunomide 10 mg.
