Geographical and epidemiological analysis of oncological incidence in paediatric and adolescent ages in a municipality of North-Western Italy: Vercelli, years 2002-2009.

INTRODUCTION: This study of the geographical incidence on the oncological mortality in young age (0-44 years) in the City of Vercelli, was aimed to address the concerns of the population and the request of municipal administrators. A detailed and sophisticated study for a City of medium-small size is due for the presence of various sources of pressure, such as a MSW incinerator just a few kilometres from the city and an intensive agricultural activity that characterizes the entire area. MATERIALS AND METHODS: The study is based on the census analysis of the population, and of the hospital admission cards, and it considers epidemiological standardized estimators and spatial analysis through Bayesian models, as well. RESULTS: Both approaches highlight Major risks for the area south of the city for major tumours such as total cancer in women (SIR / SMR significant excess of about 50%), colorectal (mean increments SMR / SIR between 3 and 4 times), ovary (mean increments SMR / SIR between 3:04 and times), and nervous system (increases 3 times for both indicators). CONCLUSION: These results deserve further studies through inferential case-control and cohort analysis, given the marginal role of the possible occupational hazards in the aetiology of juvenile cancer disorders.

Exploration study on mortality trends in the territory surrounding an incineration plant of urban solid waste in the municipality of Vercelli (Piedmont, Italy) 1988-2009.

BACKGROUND: The places, where the incinerators are located, often present problems of heterogeneous people having different environmental factors. It becomes important to evaluate the possible etiologic role of various environmental risk factors and try to quantify as they affect in the excess epidemiological. METHODS: This study considers the ISTAT index mortality due to all causes occurred from 1988 to 2009 referred to ten municipalities at south of Vercelli (Piedmont, North Western Italy) placed nearby the active incinerator from 1977 (10 latent years). The risks were calculated considering this area at risk versus the municipalities placed at North of Vercelli and versus the Vercelli. RESULTS: Some significant statically excesses emerged in the South area such as neoplasia of nervous system, liver and total of tumours. CONCLUSIONS: The study presents some drawbacks, but it is a work creditable of widening by specific research ad hoc such as cohort and/or control where it is possible to verify various environmental, occupational and occasional factors.

[The renin-angiotensin-aldosterone system during the extraction, concentration and reinfusion of ascitic fluid in cirrhotic patients]. / Il sistema renina-angiotensina-aldosterone in corso di estrazione, concentrazione e reinfusione di liquido ascitico in pazienti cirrotici.

The course of hepatic cirrhosis involves alterations to the sodium-water balance, the aetiopathogenetic causes of which are still not entirely known. At first major importance was assigned to the role of secondary hyperaldosteronism which develops during the ascitic phase. This was subsequently recognised to have only a permissive rather than determinant function. Changes in the renin-angiotensin-aldosterone (RAA) system and variations in hydrosaline balance as the extracellular volume (ECV) expands during the reinfusion of concentrated ascitic fluid have been studied. The data reported show that ECV expansion causes increased diuresis, natriuresis and osmolar clearance. The RAA system is suppressed and at the same time kaliuresis increases. The latter factor points up the role played by increased solute flow to the distal tube in the diuretico-metabolic response, where aldosterone plays a purely permissive part.

[Comparison between scintigraphic and laparoscopic findings in the study of liver diseases]. / Confronto tra rilevazioni scintigrafiche e laparoscopiche nello studio della patologia epatica.

The part played by 99Tc liver scintiscanning and laparoscopy, singly or sequentially, in the diagnosis of hepatic nodular disease was examined in a series of 316 patients. It was found that sequential employment of these two methods constituted a good diagnostic approach, since the relative sensitivity of the first could be added to the relative specificity of the second.
