Cryptic severe malaria in a Moroccan man living in Tuscany, Italy, August 2018.

In August 2018 a Moroccan man living in Tuscany developed malaria. The patient declared having not recently visited any endemic country, leading to diagnostic delay and severe malaria. As susceptibility to of Anopheles species in Tuscany is very low, and other risk factors for acquiring malaria could not be completely excluded, the case remains cryptic, similar to other malaria cases previously reported in African individuals living in Apulia in 2017.

Music-listening habits with MP3 player in a group of adolescents: a descriptive survey.

Practice of opportunistic PSA screening in the Florence District.

The widespread use of the prostate-specific antigen (PSA) test had a great impact on the rise of incidence of prostate cancer. The magnitude of opportunistic screening by PSA varies across countries, being highest in the US, and considerably lower in Europe. To estimate the opportunistic use of PSA over the period of one year (2000) in the District of Florence, we analysed the Regional Database of diagnostic exams.

Clearance of hepatitis B virus DNA and pre-S surface antigens in patients with markers of acute viral replication.

To clarify the relationship between the pre-S antigens and other serological markers of hepatitis B virus (HBV) replication, we followed up 27 patients: 21 presented with symptoms of acute hepatitis (two progressed to chronicity) and six suffered from chronic hepatitis. Pre-S1, pre-S2, HBV DNA, IgM antihepatitis core antigen (HBc), hepatitis B e antigen (HBeAg), and anti-HBe were detected in about 200 sera serially collected at different times for at least 6-12 months from the onset of clinical observation. In the early symptomatic phase of acute hepatitis, the pre-S1 and pre-S2 antigens were present in 95% of the cases and correlated well with high levels of alanine-transferase (ALT) and IgM anti-HBc, while HBV DNA was present in the sera of only six (28.

[Experience with anti-viral hepatitis B vaccine at an institution for handicapped children].

This study, conducted in an institute for handicapped children, is part of an overall effort to extend the anti-HBV vaccine to all high risk categories. Out of 50 patients, 24 (48%) registered negative results for all HBV markers. Twenty-three of these 24 (95.

[New Campylobacters in human pathology. Current findings and research contributions].

The Authors focused on the new isolates' important role in human infections (particularly pylori, laridis, hyointestinalis and Campylobacters like- organisms) by clinical, microbiological and research data. Recent knowledge about pathogenetic mechanisms of classical Campylobacters is also reported.
