ANCORA SULL'ACQUA DI CALCE. IL RESTAURO DELLA CAPPELLA CAVALCABO' A DIECI ANNI DALL'INTERVENTO

Which has often raised aversion due to its applicative limitation and poor effect. However acqua di calce (special technique for consolidation) detained good resoluts especially in a project supported be the superintendency of cultural heritage of Brescia the restoring of the paintings. The restoring of the paintings in the chapel Cavalcabò in the church S. Agostino in Cremona (painting by Bonifacio Bembo and others). This chapel in one of the most important exemples of late gothic art, which survived the restoration during the 18th and 20th centuries mainly thanks to Guido Gregorietti’s work in 1951-1952. The project of the superintendency of cultural heritage in 1994-1995 of the chapel focused on the materials, the execution technique and the deterioration the aim was to restored the original plastering dating back to 15th century and to preserve the sing left by the following interventions. Acqua di calce has proved to be a fixing and consolidation agent thanks to its basic solution and the small quantite of calcium hydroxide. Moreover it is compatible with the original plastering and the restering materials. The invention was studied carefully because of technical difficulties like the consolidation of the internal parts of the plastering. Realised on fragile materials without any pre-consolidation. The results are now discussed, more than 10 years later

Streptococcal pharyngitis in italian children: epidemiology and treatment with miocamycin.

A prospective multicentre study of Italian children with acute pharyngotonsillitis was carried out to determine the incidence of beta-haemolytic streptococcal infection and its epidemiological characteristics and to evaluate the effectiveness of a recently marketed macrolide, miocamycin. From February 1988 to March 1989, 865 children (aged 5 months to 14 years) were enrolled in 11 paediatric departments. Of these 31.9% had a positive throat culture for beta-haemolytic streptococci (26.6% group A streptococci, 5.3% group B, C, D or F). In 68.1% of the patients the throat culture did not yield any pathogen and the disease was considered to be probably viral. No epidemiological (age, season of occurrence, sex) or clinical characteristics (fever, pharyngeal hyperaemia, exudate etc.) could differentiate children with streptococcal pharyngotonsillitis from those with a probably viral one. Breese's score correctly identified only 19.1% of the cases with group A streptococcal infection. Miocamycin was given 50 mg/kg/day in 2 divided doses for 10 days in 225 children with streptococcal pharyngitis. The drug exhibited good clinical efficacy (resolution or improvement of acute signs and symptoms) in 96.3% of the children and a microbiological efficacy (eradication of the causative bacteria) in 85.3%
