Dual applicator thermal ablation at 2.45 GHz: a numerical comparison and experiments on synchronous versus asynchronous and switched-mode feeding.

Purpose: This paper compares the results obtained with numerical simulations and ex vivo experiments involving a dual applicator microwave thermal ablation system operating at a 2.45 GHz frequency, both in synchronous and asynchronous modes. Our purpose was to demonstrate that at this frequency an asynchronous or switched-mode system performs essentially as well as the synchronous one, in spite of the prevailing belief that coherence would assure better thermal (TH) synergy.

[Evaluation of interferences in electronic platelet count].

A platelets count was performed on 100 subjects using both the electronic counter and a manual method; the results obtained concerning healthy subjects are overlapping. In subjects with structural alterations regarding platelets and red blood cells, the electronic counter method has overestimated the number, yet making note of it.

[Results and observations on the research of circulating immunocomplexes in subjects with suspected autoimmune pathology].

The authors have investigated the level of circulating immune complexes (CIC) in 409 patients (some hospitalized) suffering from disease in which the presence of CIC had been suspected. The 10% (forty-one) was positive, and clinical manifestations related have shown, in the majority of patients, a close relation with diseases in which there was, or it was possible to presume, an immunological pathogenic mechanism. Besides the authors examine a case with close association between high level of CIC and leptospirosis.

[Isolation frequency of enteropathogenic Escherichia coli in the Patro distric from 1974 to 1986].

In the Prato district in the years 1974-1986 the isolation frequency of serogropus of enteropathogenic Escherichia coli on 12,251 faeces samples pertinent to infantile diarrhoea has been studied. The research reveals a constant decrease in the isolation frequency of the serogroups considered. An hypothesis is quite difficult but this finding is taking world-wide consistency: furthermore some items are distinctive of the researched district and therefore quite interesting.

[Incidence of rotavirus in pediatric patients hospitalized with gastroenteric symptoms].

In winter, for four months from November 1986 to February 1987, in one hundred samples of stool from children admitted at Pediatric Department of Prato Civil Hospital with gastroenteric symptoms, was performed the research of rotavirus. This study revealed data strictly close to the ones reported in literature: 34% of children were found positive; from these, 55.9% were under one year old, 38.
