The Cathedral of Noto, one of the most important baroque monuments that has given notoriety to the town of Noto, collapsed the 13th March 1996, about five years after the earthquake of Santa Lucia ...that took place in December 13th 1990. The collapse has pointed out serious deficiencies in constructive materials of pilasters, even in their capacity to support vertical loads. The earthquake of 1990, therefore, has acted as "the last blow", coming after a long period of fatigue. The geometry of the church was
Objective The aim of this study was to perform a comparative analysis of precision of 3 apex locators: Root ZX, Elements Diagnostic Unit and Apex Locator, and RomiAPEX D-30. Study design Forty ...extracted single-rooted human teeth were selected. After endodontic access, measurement of the anatomical tooth length was visually performed by insertion of a K-file size 10 until its tip could be observed at the apical foramen with aid of a light microscope at 8× magnification. Following, the teeth were placed in a plastic box with alginate and electronically measured with the 3 apex locators at 1-mm short of the apical foramen. Results The results revealed a precision rate of 97.5% for Root ZX, 95% for Elements Diagnostic Unit and Apex Locator, and 92.5% for RomiAPEX D-30, with no statistically significant difference between them (chi-square test, P > .05). Conclusion The results confirm that all these electronic devices can accurately determine the root canal length within 1 mm from the apical constriction.

Summary
A trial was carried out to assess the value of ibuprofen in relieving the symptoms and signs in 40 patients suffering from inflammatory phlebopathies of the lower limbs. Ibuprofen was given ...in a dosage of 900 mg. daily for periods ranging from 7 to 28 days. Spontaneous pain, redness and oedema showed a marked reduction, on average by the third day, although pain on pressure persisted for about 10 days. Body temperature returned to normal within a few hours. The results were assessed as excellent in 10, good in 19,fair in 8, and poor in 3 patients. Side-effects were reported inonly 3 patients and were mild.
