[Evaluation of the levels of radiofrequency electromagnetic fields in the territory of the city of Bari in outside and inside environments].

In this study we measured the levels of the high frequency field in the proximity of non-ionizing radiation sources (wireless transmitting stations for mobile telephones and radio and television transmitters) in nine districts of the city of Bari. The measurements were taken both inside and outside closed environments. For the indoor measurements we took into account electromagnetic field generating equipment (VDT, electric domestic appliances, mobile telephones) in working and non-working order and with the windows open and shut respectively.

[Indoor radon pollution in houses in the Apulian Region of Italy and evaluation of the probability of lung cancer in the population].

Background: Radon-222 is a gaseous radioactive chemical which can be transformed into other radioactive chemicals, defined as "products of decay" or "radon's daughter". The modality of radon penetration into the buildings depends on the convection motion created in the ground, which suck it back, so causing the penetration. The principal effect on human health is the increase risk of lung cancer, in proportion to the concentration and the time people spend indoors with exposure to radon.

[Measurement of radon concentrations in schools at 2 communities of Puglia and oncologic risk].

Measurements of radon's concentration have been effected in the schools of two communes of Puglia: Polignano and Valenzano. The average concentration of radon, based on the prospecting effected in the research period (spring/summer 1997), appeared, for both communes, lower than national average (75 Bq/m3). However, these average concentrations is below estimated caused of the limitation of the research period, owing to organization only at the period spring/summer.

[Blood groups of the ABO system and survival rate in gynecologic tumors].

A retrospective analysis of 968 women affected by gynecological tumors was conducted to assess the existence of a difference in survival between patients with different blood groups. Data are presented on 237 cases of endometrial cancer, 92 cases of ovarian cancer and 639 cases of invasive cervix cancer, detailing their ABO blood antigenic phenotypes, the stage of neoplasia and the treatment received. With regard to endometrial cancer, a sensibly better 5-year and 10-year survival is associated with blood group 0 if compared with blood group A.

[Dentinal lesions caused by the use of endodontic posts].

An endodontic treatment has been effected on 36 extracted teeth, using drills; certain endodontic posts presently on the market have been successively inserted inside 18 teeth: Flexipost (Essential Dental System); Parapost Plus (Whaledent); dentatus (Dentatus). The teeth have been sectionized and watched through a photomicroscope to check an eventual presence of dentinal damages.
