Do Emergency Department Observation Units Help Prevent Revisits for Patients with Renal Colic?

Introduction: Renal colic is generally considered a diagnosis appropriate for discharge home once pain is adequately controlled and no other admission criteria are met. The increasing prevalence of ED observation units (EDOU) represent another disposition option for patients with renal colic. In this study, we sought to describe the rates of 14-day revisits for renal colic among patients placed in an EDOU as compared to those discharged from the ED.

[Ethics in clinical practice and in health care].

The clinical ethics is the identification, analysis and solution of moral problems that can arise during the care of a patient. Given that when dealing with ethical issues in health care some risks will be encountered (talking about ethics in general, or as a problem overlapped with others in this area, or by delegation to legislative determinations) in the text certain important aspects of the topic are examined. First of all ethics as human quality of the relationship between people for the common good, especially in health services where there are serious problems like the life and the health.

Increased CD154 expression in uninfected infants born to HIV-positive mothers exposed to antiretroviral prophylaxis.

Although prevention of mother-to-child HIV transmission by antiretroviral drugs has been shown to be effective, the short- and long-term effects of treatment are not well known. Several reports suggest that antiretroviral drugs act not only by inhibiting viral replication, but also by improving antiviral immunity. In particular, treatment with nucleoside analogs was found to increase CD40 ligand (CD40L; CD154) levels, an inducible molecule expressed on activated T lymphocytes.

A 5' regulatory sequence containing two Ets motifs controls the expression of the Wiskott-Aldrich syndrome protein (WASP) gene in human hematopoietic cells.

The recently-identified Wiskott-Aldrich syndrome protein gene (WASP) is responsible for the Wiskott-Aldrich X-linked immunodeficiency as well as for isolated X-linked thrombocytopenia (XLT). To characterize the regulatory sequences of the WASP gene, we have isolated, sequenced and functionally analyzed a 1.6-Kb DNA fragment upstream of the WASP coding sequence.
