No full textSensitivity of cloud radiative forcing to changes of microphysical parameters measured by the CLOUDS mission
Full text linkCLOUDS (a Cloud and Radiation monitoring satellite) is a study for a satellite mission designed to provide the gross vertical profile, the internal structure. the radiative and the imaging features of clouds. This subject is addressed by several missions designed for process study intent. CLOUDS, instead, is designed for providing data of routine use in long-term Numerical Weather Prediction (NWP) and General Circulation Model (GCM). User requirements have been collected from various sources, and instruments concepts derived to meet those requirements. However, to establish the sensitivity of a GCM to the targeted parameters and confirm the soundness of the specified requirements (mainly accuracy and vertical resolution), special effort had to be placed. The present paper offers a rather complete assessment of the range of usefulness that CLOUDS measurements may have on the radiative calculation. To this purpose, the cloud forcing was computed as a function of cloud parameters by using a radiative model that has been applied in the GCM of the Laboratory for Atmospheres at the NASA Goddard Space Flight Center. The results show that, in most cases, the model response to the addressed cloud parameters is good if the error is within the specified limit. This is better demonstrated for relatively large particle sizes, for ice better than for liquid water, for low optical thickness and for low cloud cover. The model, however, suggests that more stringent requirements would be appropriate when small particles are considered
Racecadotril at the Beginning of Pediatric Gastroenteritis: A Small Experience of a Primary Level Hospital
No full textparents because of it does not reduce the frequency of bowel movements and the loss of fluids from the gut nor
shortens the duration of the disease.
Racecadotril reduces secretions of intestinal fluids but it doesn’t inhibit the intestinal motility.
Methods: We retrospectively reviewed 61 children affected by mild acute gastroenteritis consecutively admitted
to our Pediatric Service along two years (2009 to 2010).
The children treated with Racecadotril plus OR were 26 and those treated with OR alone were 35.
Results: Out of 35 children treated with Racecadotril+OR, 17 patients (65.4%) were discharged within twentyfour
hours after admission because of a marked improvement in symptoms compared with the 14/35 patients
(40.0%) of children treated with OR alone with statistically significant values (p<0.05).
Children, converted to parenteral therapy due to the worsening of symptoms, were 26.9% and 42.9% in the
OR+Racecadotril Group and in the OR Group respectively. We have had no side effects regarding the use of
Racecadotril.
Conclusions: Our hospital is a Primary Level Hospital and we often assess children at the beginning of their
symptoms. This allows us to administer Racecadotril at the onset of diarrhoea.
Our sample is small, but it shows that the early use of Racecadotril shortens the hospitalization and decreases
the rate of conversion to parenteral rehydration therapy in children with mild gastroenteriti
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Helicobacter pylori infection: Sequential therapy followed by levofloxacin-containing triple therapy provides a good cumulative eradication rate. (I.F.3.151)
No full textBackground: In the eradication of H. pylori infection, even today, the main international guidelines recommend the triple therapy as first-line regimen, although its effectiveness is clearly decreasing. As second-line treatment, the bismuth-containing quadruple therapy is the most used regimen, although several other therapies are studied. The Italian guidelines recommend, alternatively, sequential therapy or triple therapy as first-line treatment and levofloxacin-containing triple therapy as second-line regimen. We wanted to assess the overall eradication rate of Helicobacter pylori infection in two therapeutic rounds following the Italian guidelines in clinical practice. Materials and Methods: We treated 231 consecutive Helicobacter pylori-positive patients by sequential therapy and we verified the eradication 8-10 weeks after treatment by stool antigen test. Patients positive for stool antigen test received levofloxacin-containing triple therapy, as second-line therapy, according to Italian Guidelines and they were again submitted to the fecal test 8-10 weeks after the end of treatment. Results: In the first-line regimen, we obtained an eradication rate of 92.6%, in the second-line of 75.0% and as cumulative result we achieved a 97.8% of eradication, in per-protocol analysis. Conclusions: Sequential therapy as first-line and levofloxacin-containing triple therapy as second-line represent a good combination to eradicate Helicobacter pylori infection in only two rounds
