BACKGROUND: Most of surgical site infections (SSI) are caused by commensal and pathogenic agents from the patient's microbiota, which may include antibiotic resistant strains. Pre-surgical asepsis of the skin is one of the preventive measures performed to reduce SSI incidence and also antibiotic resistance dissemination. However, in veterinary medicine there is no agreement on which biocide is the most effective. The aim of this study was to evaluate the effectiveness of two pre-surgical skin asepsis protocols in dogs...

Having previously highlighted the gelation of pectin with chlorhexidine (CX), pectinate microparticles were prepared here by vibrational prilling using CX, not only as an active ingredient encapsulated but also as a cross-linking agent. CX amount required for pectin gelation was smaller than usual dications (Ca2+ , Zn2+ ) used as cross-linking agent for pectin ionotropic gelation: CX seemed to bind more easily to pectin chains that could be explained by its large molecular size. Three batches of CX microparticles with different mean size were prepared...

N-nitrosamines are a group of potent human carcinogens that can be formed during oxidative treatment of drinking water and wastewater. Many tertiary and quaternary amines present in consumer products (e.g., pharmaceuticals, personal care and household products) are known to be N-nitrosodimethylamine (NDMA) precursors during chloramination, but the formation of other N-nitrosamines has been rarely studied. This study investigates the specific and total N-nitrosamine (TONO) formation potential (FP) of various precursors from nitrogen-containing micropollutants (chlorhexidine, metformin, benzalkonium chloride and cetyltrimethylammonium chloride) and tertiary and quaternary model amines (trimethyl amine, N,N-dimethylbutyl amine, N,N-dimethylbenzyl amine and tetramethyl ammonium)...

Haematemesis is a worrying sign, generally related to acute upper gastrointestinal bleeding and potentially life-threatening condition. We present a case of a 15-year-old Caucasian girl who was belatedly diagnosed with oral bleeding because it was not related to the most common aetiologic factors. In fact, she was undergoing orthodontic treatment with a Nance palatal arch, an appliance used to reinforce anchorage during teeth movements. In her case haematemesis was a sign of inflammation and necrosis occurring in the palatal mucosa, under the acrylic button of palatal arch...
