Surveillance on Healthcare Workers During the First Wave of SARS-CoV-2 Pandemic in Italy: The Experience of a Tertiary Care Pediatric Hospital.

Healthcare workers (HCWs) play a central role in handling the ongoing coronavirus disease 2019 (COVID-19) pandemic. Monitoring HCWs, both symptomatic and asymptomatic, through screening programs, are critical to avoid the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in the hospital environment to rapidly identify and isolate infected individuals and to allow their prompt return to work as soon as necessary. We aim to describe our healthcare surveillance experience (April 2-May 6, 2020) based on a combined screening consisting of real-time PCR (RT-PCR) on nasopharyngeal (NP) swabs and rapid serologic tests (RST) for SARS-CoV-2 in all HCWs of Meyer Children's University Hospital in Florence.

[An epidemiological evaluation of proximal femur fracture on a population living in the area of the Florence Local Health Trust].

Proximal femur fracture is a relevant issue of public health due to its high prevalence in elderly people and high social costs. We performed an epidemiological description of the event based on the data derived from the hospital discharge reports over a 5-year period, from 1997 to 2001, referred to a mean population of 796,990 persons. During this period, the disease incidence rate, estimated on hospital admissions, is high (higher than national average), although rather constant over years: average values are 777.

[Detection of the human papillomavirus in hyperplastic and cancerous prostatic tissue with PCR].

Human papillomavirus (HPV) infections are frequently associated with benign, pre-malignant and malignant lesions of the female genital region and male anogenital tract. Recently several studies have been performed to evaluate the presence of HPV in the adenomatous and carcinomatous prostatic tissue for the epidemiological implications due to the sexual transmission, and for the possible etiologic role in the development of prostatic carcinoma, first cause of death from neoplasia in men over 60 years in the developed countries. The role of HPV is still controversial since some authors evidenced the virus in prostatic tissue others did not detect its presence.

Indomethacin-induced intestinal ulcers are associated with an increased number of peripheral T lymphocytes in the rat.

Indomethacin (8 mg/kg per os) induced small-intestinal ulcers which were associated with an increased percentage of total number and T-helper peripheral lymphocytes. An increase in intestinal flora and a decrease in mucosal permeability due to indomethacin treatment are among the factors which favour the cytotoxic T-cell reactions and the resulting increase in lymphocytes.
