Performance Assessment of Two Low-Cost PM and PM Monitoring Networks in the Padana Plain (Italy).

Two low-cost (LC) monitoring networks, PurpleAir (instrumented by Plantower PMS5003 sensors) and AirQino (Novasense SDS011), were assessed in monitoring PM and PM daily concentrations in the Padana Plain (Northern Italy). A total of 19 LC stations for PM and 20 for PM concentrations were compared vs. regulatory-grade stations during a full "heating season" (15 October 2022-15 April 2023).

Serum levels of benzydamine following the topical use of this drug in gynecology.

The serum levels of benzydamine were studied after administration by vaginal douching (at a concentration of 0.0%) to patients with and without vaginal inflammation. In both experimental groups benzydamine produced similar serum concentrations which were lower than those obtained by other administration routes, excluding the possibillity of eventual systemic effects.
