Drugs That Induce Gingival Overgrowth Drive the Pro-Inflammatory Polarization of Macrophages In Vitro.

Several attempts have been made to elucidate the pathogenesis of drug-induced gingival overgrowth (DIGO), which is triggered by the chronic use of certain drugs that fall into three main categories: anticonvulsants, immunosuppressants, and calcium channel blockers. Previous research suggests that cytokines and impaired cellular functions play a role in DIGO. Of particular interest are macrophages, immune cells that can switch between M1 (pro-inflammatory) and M2 (anti-inflammatory) phenotypes in response to exogenous signals and stimuli.

Hepatitis C virus (HCV) infection is a significant public health problem affecting 58 million people worldwide, including 3.9 million in Europe. Many of these infections go undiagnosed because chronic infection is often asymptomatic.

Sodium-hyaluronate mouthwash on radiotherapy-induced xerostomia: a randomised clinical trial.

Introduction: Radiotherapy-induced xerostomia (RIX) is one of the most common adverse effects of radiotherapy (RT) in head and neck cancer patients (HNC) and a major determinant of survivors' quality of life. The primary objective was to evaluate the reduction of patients' xerostomia symptoms after the utilisation of a sodium-hyaluronate mouthwash compared to a placebo solution. The secondary objectives were to evaluate the improvement of quality of life and to evaluate the patients' satisfaction.

An Unconventional Oral Candidiasis in an Immunocompetent Patient.

Oral candidiasis (OC) is an opportunistic fungal infection of the oral mucosae, sustained by or other non-albican species (NAC), usually eradicated by conventional antifungals of the classes of azoles, polyenes, or derivative from echinocandins. OC usually occurs under predisposing local or systemic factors. is an opportunistic strain that is rarely responsible for human infection and occurs mainly in severe immunocompromised states.

Oral Candidiasis and Novel Therapeutic Strategies: Antifungals, Phytotherapy, Probiotics, and Photodynamic Therapy.

Oral candidiasis is an opportunistic infection of the oral mucosa sustained by fungi of the genus Candida. Various Candida species, with a predominance of C. albicans, normally a saprophyte of the oral cavity, may become virulent and infect the oral mucosa with variegated clinical presentation, in case of imbalance of the oral microbiota, the presence of local predisposing factors and systemic conditions that weaken the immune system.

Image postproduction analysis as a tool for evaluating topical photodynamic therapy in the treatment of oral lichen planus.

Background: Topical Photodynamic Therapy (PDT) is a minimally invasive technique used in various medical specialties. The method involves the use of a light source and a photosensitizer leading to the release of Reactive Oxygen Species and a cytotoxic effect on lesional tissue. PDT can treat various lesions , and in particular Oral Potentially Malignant Disorders (OPMD).

High-Definition Ultrasound Characterization of Squamous Carcinoma of the Tongue: A Descriptive Observational Study.

High-definition ultrasonography is a diagnostic tool that uses sound echoes to produce images of tissues and organs. In the head and neck region, ultrasounds have been used to diagnose different types of lesions. The intraoral approach was shown to be a real-time, non-invasive way to characterize oral lesions.

Assessment of sleep disturbance in oral lichen planus and validation of PSQI: A case-control multicenter study from the SIPMO (Italian Society of Oral Pathology and Medicine).

Background: The wellbeing of oral lichen planus patients (OLPs) may be strongly influenced by a poor quality of sleep (QoS) and psychological impairment. The aims were to analyze the prevalence of sleep disturbance, anxiety, and depression in OLPs and to validate the Pittsburgh Sleep Quality Index (PSQI) in OLPs.

Methods: Three hundred keratotic OLPs (K-OLPs), 300 with predominant non-keratotic OLP (nK-OLPs), and 300 controls were recruited in 15 Italian universities.

Oral Microbiota Features in Subjects with Down Syndrome and Periodontal Diseases: A Systematic Review.

Down syndrome (DS) is a genetic disorder associated with early-onset periodontitis and other periodontal diseases (PDs). The present work aimed to systematically review the scientific literature reporting studies in vivo on oral microbiota features in subjects with DS and related periodontal health and to highlight any correlation and difference with subjects not affected by DS, with and without PDs. PubMed, Web of Science, Scopus and Cochrane were searched for relevant studies in May 2021.

Noninvasive Imaging Methods to Improve the Diagnosis of Oral Carcinoma and Its Precursors: State of the Art and Proposal of a Three-Step Diagnostic Process.

Oral squamous cell carcinoma (OSCC) is the most prevalent form of cancer of lips and oral cavity, and its diagnostic delay, caused by misdiagnosis at the early stages, is responsible for high mortality ratios. Biopsy and histopathological assessment are the gold standards for OSCC diagnosis, but they are time-consuming, invasive, and do not always enable the patient's compliance, mainly in cases of follow-up with the need for more biopsies. The use of adjunctive noninvasive imaging techniques improves the diagnostic approach, making it faster and better accepted by patients.
