[Patient participation through active listening. About the remodeling of an extractions service].

Background And Objective: From listening to patients there arises the possibility of improving both the care and the health infrastructure that users frequent. Our purpose of study was to explore the perception of users about the means and the care received involved in a hospital service through active listening, and to evaluate the satisfaction perceived after the opening of the renovated area.

Methods: A mixed methodology evaluative investigation was carried out within the context of the Extraction Service of the Costa del Sol Hospital, using qualitative methodology to assess the perception of users, and quantitative methodology through a satisfaction survey to identify the change after remodeling of the area.

Renal failure and acquired hypothyroidism.

The effects of thyroid metabolism on renal function in children are barely referred to in the literature. Primary hypothyroidism is known to be associated with a consistent elevation in serum creatinine levels. This is essentially because of the hypodynamic state that occurs in hypothyroidism, leading to a reduced glomerular filtration rate and hypercreatinemia.

[Alterations of nuclear maturity in spermatozoids of males with antecedents of cryptorchidism].

The association between infertility and cryptorchidism is an accepted fact, usually attributed to the oligozoosperm, asthenozoosperm or teratozoosperm presented in ejaculation products of males with this antecedent. The nuclear maturity in a sample of men with antecedents of cryptorchidism have been studied and these results have been compared to those of a control group. The results of this work show the deficient transformation of nuclear proteins to protamines in males with antecedents of cryptorchidism compared to the control group, due to the remaining of immature histones.

Downmodulation of HLA class I expression by dexamethasone in MCF-7 cell line.

Several reports have shown the importance of MHC class I antigens in enabling the host to regulate tumour growth in vivo. Glucocorticoid hormones have strong immunosuppressive effects and are known to be regulators of gene transcription. In this report the expression of Major Histocompatibility Complex (MHC) class I antigens in six breast carcinoma cell lines have been studied before and after treatment with the synthetic glucocorticoid dexamethasone.
