[Successful trial for introduction of the WHO surgical safety checklist].

Background: The WHO Surgical Safety Checklist was published in 2008 as an attempt to decrease complications and death from surgery. This checklist was implemented and evaluated using questionnaires in an intermediate size general hospital. We attempted to confirm how the WHO checklist has been implemented and assessed as a medical safety system.

[Ultrasound role in assessment of vesicoureteral reflux endoscopic treatment results].

Introduction: Since the beginning of the application of the RVU treatment, the use of the ultrasound was used taking into account two main indications/symptoms: a) identification of the complications; b) assessment of the result (visualization of the implanted material and the presence of the "uretheral jet" by means or through/of ecodoppler-color).

Objective: To determine the value of the ultrasound in the assessment of the result of the endoscopic treatment of the RVU and in the detection of its complications.

Material And Method: From 2001-2002 we have carried out the endoscopic treatment to an overall of 261 ureteral units of all degree and etiology.

Comparison of the X-ray absorption properties of the binuclear active site of molluscan and arthropodan hemocyanins.

The structural characteristics of oxy- and deoxy-hemocyanins have been investigated using X-ray absorption spectroscopy both in the near-edge (XANES) and for the first shell contribution in the EXAFS region. Several arthropodan and molluscan hemocyanins have been studied in order to trace the inter- and intra-phyla differences. The XANES spectra of oxy-hemocyanins of the different species are remarkably similar, consistent with a very strongly conserved co-ordination geometry of the copper active site.

Significance of rises in urinary bicarbonate contents and pH related with increased atmospheric carbon dioxide in Tokyo.

Atmospheric carbon dioxide concentration was measured at several locations in Tokyo, for two weeks, in December, 1995 and 1996, and was found to be increased up to 550 ppm, while it was shown by us to be 450 ppm in December, 1994. These results demonstrate that atmospheric carbon dioxide is steadily increasing at faster rates in Tokyo than we expect, though it has been considered that the atmospheric carbon dioxide is still as much as 350 ppm. Bicarbonate concentration and pH of urine of 13 medical students in Tokyo were also measured for the same period in December of 1995 and 1996, and were found to be significantly increased compared with the values that were reported in the past.

[Our experience in portal cavernomatosis in childhood: cross-sectional study and analysis of results].

A retrospective and transversal study of our patients with portal cavernomatosis is developed, with the aim of comparing the evolution and the present status of the patients that have undergone different therapeutical approaches. Between 1975 and 1995, 15 patients with portal cavernomatosis have been treated. Personal history, signs and symptoms at the moment of diagnosis, and treatment were analyzed.
