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

Pregnancy outcome among HIV positive and negative intravenous drug users

Objective: To analyze determinants of pregnancy outcome, among HIV infected and uninfected intravenous drug users. Study design: A total of 315 pregnant current intravenous drug users, IVDU (151 HIV infected and 164 HIV uninfected subjects) were referred to the Center for Pregnant Drug Addicts of the Mangiagalli Clinic, Milan, Italy, for internatal care and delivery between 1985 and 1993. Results: HIV uninfected and infected mothers did not differ significantly according to type of pregnancy, gestational age at childbirth, mode of delivery, pregnancy outcome and newborn weight, height, head circumference, sex and Apgar at 1 and 5 min. Out of 133 children (born to HIV infected mothers) for whom HIV status was available, 20 (15%) were HIV infected or developed AIDS-related signs and symptoms during a 24 months follow-up. The distribution of HIV infected and non infected infants was not significantly different as regards maternal CD4 lymphocyte count, week of gestation at birth, mode of delivery, infant weight, height, head circumference and Apgar at 1 and 5 min. Conclusion: Our data show that HIV infected women in the early stages of HIV infection are not at a higher risk of adverse course of pregnancy than HIV uninfected women. Vertical transmission rates were not associated to newborn characteristics

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%

Infezioni sessualmente trasmesse e salute sessuale: introduzione di attivit\ue0 educative integrate nel contesto scolastico italiano

Sexually Transmitted Infections (STIs) are widely spread worldwide. Young people sometimes do not know about STIs and frequently they do not know who to contact or talk to. Sex education represents one of the most impor- tant means of promoting sexual health of youth and an essential component of the comprehensive strategy for HIV and STIs prevention in Europe. An analysis of the national and international documentary references and the educational activities implemented in the schools of the national territory was carried out within the framework of EduForIST project, funded by the Ministry of Health
