antimicrobial activity of ozonated oil in liposome eyedrop against multidrug-resistant bacteria.

Bacteria are the most common causative agents of ocular infections. Treatment with topical broad-spectrum antibiotics is recommended in severe cases. However, antibiotic resistance has become a major concern in recent years, although antibiotics are generally effective in treating ocular infections.

Surveys on Exposure to Reptile-Associated Salmonellosis (RAS) in the Piedmont Region-Italy.

Reptile-associated salmonellosis (RAS), infection in humans, is acquired through contact with reptiles. Reptiles have become popular pet animals, and RAS is likely to be an underestimated but growing problem. No epidemiological data about RAS are routinely collected in Italy.

Using Microbiological Sampling to Evaluate the Efficacy of Nasofibroscope Disinfection: The Tristel Trio Wipes System in Ear-Nose-Throat (ENT) Endoscopy.

Disinfection and sterilization are needed for guaranteeing that medical and surgical instruments do not spread contagious microorganisms to patients. The aim of this study was to evaluate the efficacy of a simple manual technique of high-level disinfection (HLD) of flexible fiberoptic nasofibroscopes (FFNs) with wipes impregnated with a chlorine dioxide solution (Tristel Trio Wipes System-TTW) against a conventional automated washer machine (Soluscope ENT, Cimrex 12-AW). FFNs used in 62 patients undergoing endoscopy at an ENT clinic were sampled according to an aseptic procedure.

Subgingival Microbiota in White Patients With Desquamative Gingivitis: A Cross-Sectional Study.

Background: Presence of epithelial desquamation, erythema, and erosions on gingival tissue is usually described in the literature as desquamative gingivitis (DG). A wide range of autoimmune/dermatologic disorders can manifest as DG, although the two more common are oral lichen planus and mucous membrane pemphigoid. The aim of this study is to investigate prevalence of 11 periodontopathogenic microorganisms in patients with DG and to compare it with the microbiologic status of individuals affected by plaque-induced gingivitis (pGI).

Rapid Identification of Microorganisms from Positive Blood Culture by MALDI-TOF MS After Short-Term Incubation on Solid Medium.

Matrix-assisted laser-desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry (MS) is a useful tool for rapid identification of microorganisms. Unfortunately, its direct application to positive blood culture is still lacking standardized procedures. In this study, we evaluated an easy- and rapid-to-perform protocol for MALDI-TOF MS direct identification of microorganisms from positive blood culture after a short-term incubation on solid medium.

Nasal and Tracheal Microbial Colonization in Laryngectomized Patients.

Objective: Complete separation of upper and lower respiratory tract after total laryngectomy results in loss of physiological nasal functions and presence of "unconditioned" inspired air in lower airways. Aim of this study is evaluating the presence of a microbial colonization of nasal cavities and trachea in laryngectomized long-term survivors.

Methods: Twenty-five laryngectomized patients underwent symptoms' anamnestic evaluation, endoscopic fiber optic nasal and tracheal examination, specimen collection for microbiological exam, and culture.

Chromosome abnormalities additional to the Philadelphia chromosome at the diagnosis of chronic myelogenous leukemia: pathogenetic and prognostic implications.

Additional chromosome abnormalities (ACAs) occur in less than 10% of cases at diagnosis of Philadelphia chromosome (Ph)-positive chronic myelogenous leukemia (CML). In some cases, on the basis of the persistence of the ACAs in Ph-negative cells after response to imatinib, a secondary origin of the Ph chromosome has been demonstrated. In this study, the possible prognostic value of this phenomenon was evaluated.

Cryptic translocation of PML/RARA on 17q. A rare event in acute promyelocytic leukemia.

Cryptic translocations in acute promyelocytic leukemia are rare. Usually the gene fusion PML/RARA is located on chromosome 15. Combined cytogenetic, fluorescence in situ hybridization (FISH), and molecular (polymerase chain reaction [PCR]) analysis were employed for the diagnosis and precise localization of the fusion gene.
