Oral Candida and psoriasis: Is there association? A systematic review and trial sequential analysis.

To assess (i) the prevalence of oral colonization by Candida spp. in patients with psoriasis and (ii) the prevalence of oral lesions associated with Candida spp. in patients with psoriasis and identify the risk factors for oral lesions. A systematic review was conducted in accordance with PRISMA criteria. The PROSPERO registration code is CRD42019127178. PubMed, Scopus and Web of Science were used as search engines. Meta-analyses and trial sequential analyses were performed. Among the 5805 retrieved records, nine articles were included. Among 530 psoriatic patients, 255 patients had an oral Candida spp. colonisation with an odds ratio (OR) = 3.44 (95% CI:2.38-5.00). Among 490 psoriatic patients, 43 patients developed oral Candida spp. lesions with an OR = 5.31 (95% CI:1.04-27.23). Among the patients without the main predisposing factors for infections, psoriatic patients had a higher OR (3.48, 95% CI: 2.0-6.0) for Candida spp. colonization, but not for Candida spp. infection, when compared with healthy controls (p-value > 0.05). Meta-analysis showed a higher risk of Candida spp. colonisation in patients with psoriasis. Patients who received immunosuppressive therapies were also at higher risk of developing oral lesions. Further studies are needed to understand these associations.

ELISA detection of anti-desmoglein 1 and anti-desmoglein 3 and indirect immunofluorescence in oral pemphigus: A retrospective study.

OBJECTIVE: The aim of this study was to test the efficacy of autoantibodies to desmoglein 1 and desmoglein 3 detected by ELISA and indirect immunofluorescence in the diagnosis of oral pemphigus and to correlate the antibody titres with the severity of the disease. MATERIALS AND METHODS: We report a retrospective cohort study of 22 patients with oral pemphigus and 64 controls from a single tertiary centre. Data about histopathological examination, direct immunofluorescence, indirect immunofluorescence and ELISA were analysed. Global validation of ELISA and IIF both alone and combined was established by calculating sensitivity, specificity, accuracy and both positive predictive value and negative predictive value. The relationship between Oral Disease Severity Score values and ELISA titres was analysed using Pearson's coefficient. RESULTS: The best diagnostic performance was observed for anti-desmoglein 3 ELISA. The sensitivity was 75% and specificity 100% and positive predictive value and negative predictive value were 92.5% and accuracy 93.9%. The level of agreement with histopathology + direct immunofluorescence was substantial (k = .758). Anti-desmoglein 3 titres showed a significant correlation with Oral Disease Severity Score (p < .05). CONCLUSIONS: Serological tests are commonly employed during clinical practice as adjunctive tools. Anti-desmoglein 3 ELISA should be considered as a first-instance diagnostic test for oral pemphigus early detection.

Prevalence of HPV in patients affected by oral Lichen planus: A prospective study using two different chair-side sampling methods.

BACKGROUND: Human Papillomavirus (HPV) role in oral potentially malignant lesions remains unclear. Aims of this study were to evaluate the prevalence of HPV infection in a cohort of patients affected by oral lichen planus, to analyze the genotypes involved, and to compare the performance of two specimen collection methods: brushing and biopsy. METHODS: Consecutive patients with oral lichen planus were enrolled. Each patient's clinical and anamnestic data were recorded before he/she underwent brushing and biopsy procedures. The collected samples were analyzed using RT-PCR. Prevalence of HPV infection was evaluated considering cytobrush and biopsy outcomes alone and combined. Correlation between HPV presence and sex, age, smoke, alcohol, kind of lichen planus, Hepatitis C virus, and involved mucosae was analyzed using chi-square test (significance at P < .05). Cohen's k coefficient was employed to compare brushing and biopsy. RESULTS: Fifty-two patients affected by oral lichen planus were enrolled. Total HPV prevalence was 17%, when considering only the biopsy and the cytobrush the prevalence was 15% and 6%, respectively. None of the considered variables showed significant correlation with HPV (P > .05). The concordance between the two methods was "fair" (k = .305). CONCLUSIONS: The biopsy appears more reliable than cytobrush to detect HPV in course of oral lichen planus. No statistical correlation emerged with the analyzed variables. The most frequently detected genotypes were HPV 6 and 11, while only two cases presented with HPV 16 and 53, known as human oncogenic.

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. The participants were subjects affected by Down syndrome (DS) with and without periodontal diseases; the study compared subjects with periodontal diseases but not affected by DS, and DS without periodontal diseases; the outcomes were the differences in oral microbiota/periodontopathogen bacterial composition among subjects considered; the study design was a systematic review. Study quality was assessed with risk of bias in non-randomized studies of interventions (ROBINS-I). Of the 954 references retrieved, 26 studies were considered. The conclusions from the qualitative assessment of the papers revealed an increasing knowledge over the last years of the microbiota associated with DS and their periodontal diseases, in comparison with healthy subjects and subjects with other kinds of mental disabilities. Few data have emerged on the mycobiome and virobiome of DS, hence, further investigations are still necessary.

Cannabinoids Drugs and Oral Health-From Recreational Side-Effects to Medicinal Purposes: A Systematic Review.

BACKGROUND: marijuana, the common name for cannabis sativa preparations, is one of the most consumed drug all over the world, both at therapeutical and recreational levels. With the legalization of medical uses of cannabis in many countries, and even its recreational use in most of these, the prevalence of marijuana use has markedly risen over the last decade. At the same time, there is also a higher prevalence in the health concerns related to cannabis use and abuse. Thus, it is mandatory for oral healthcare operators to know and deal with the consequences and effects of cannabis use on oral cavity health. This review will briefly summarize the components of cannabis and the endocannabinoid system, as well as the cellular and molecular mechanisms of biological cannabis action in human cells and biologic activities on tissues. We will also look into oropharyngeal tissue expression of cannabinoid receptors, together with a putative association of cannabis to several oral diseases. Therefore, this review will elaborate the basic biology and physiology of cannabinoids in human oral tissues with the aim of providing a better comprehension of the effects of its use and abuse on oral health, in order to include cannabinoid usage into dental patient health records as well as good medicinal practice. METHODS: the paper selection was performed by PubMed/Medline and EMBASE electronic databases, and reported according to the PRISMA guidelines. The scientific products were included for qualitative analysis. RESULTS: the paper search screened a total of 276 papers. After the initial screening and the eligibility assessment, a total of 32 articles were considered for the qualitative analysis. CONCLUSIONS: today, cannabis consumption has been correlated to a higher risk of gingival and periodontal disease, oral infection and cancer of the oral cavity, while the physico-chemical activity has not been completely clarified. Further investigations are necessary to evaluate a therapeutic efficacy of this class of drugs for the promising treatment of several different diseases of the salivary glands and oral diseases.

Early Childhood Oral Health Impact Scale (ECOHIS): Literature review and Italian validation.

OBJECTIVE: The Early Childhood Oral Health Impact Scale (ECOHIS) is a questionnaire to elucidate the relationship between parental perception of the quality of life of their preschool children and their oral health status. Aim of the present work was to validate an Italian ECOHIS version and review the literature. METHODS: After adapting the original ECOHIS questionnaire from English to Italian (I-ECOHIS), I-ECOHIS was administered to parents of children afferent to the Dental Clinic of the University of Campania "Luigi Vanvitelli," regardless of age. Children under 6 years of age underwent anamnestic survey and physical examination, to correlate the dmft index with the ECOHIS score. RESULTS: 366 children have come to our observation. I-ECOHIS was administered to all parents to establish its comprehensibility. 87 children (44 females and 43 males) under 6 years (5.2 ± 1.4 years) underwent dmft evaluation to determine I-ECOHIS/oral health status correlation. Among the 87 children examined, the higher total score reached was 25/50. ANOVA analysis confirmed statistically significant correlations between ECOHIS score and dmft = 0 vs dmft equal/higher than 4. CONCLUSION: The present pilot study validated the I-ECOHIS questionnaire and revealed to be a good tool to distinguish children without caries experience from those with a high dmft. However, it was not correlated with the intermediate dmft level, thus confirming the importance of screening for caries.

In vivo microstructural analysis of enamel in permanent and deciduous teeth.

Confocal microscope was used to analyze human enamel from 10 deciduous and 10 permanent teeth. Optically sectioned images were obtained. A more intense autofluorescence was found in primary teeth. This finding might be due to the greater presence of organic substances in deciduous enamel. The mean prism diameter measurement in permanent teeth enamel was 3.150 µm and 2.602 µm in deciduous teeth. The mean prism diameter in deciduous teeth was statistically least. The results indicate that a confocal microscope may be of help in analyzing and defining the microscopic features of human enamel.

Non-invasive in vivo visualization of enamel defects by reflectance confocal microscopy (RCM).

The enamel defects (EDs) may present with a variety of clinical manifestations with increasing severity from the sole appearance of pale discoloration to remarkable structural alterations. EDs are responsible for higher caries receptivity. In vivo reflectance confocal microscopy (RCM) allows to image in vivo at microscopic resolution of the dental surface, thus avoiding the tooth extraction and the sample preparation because of its ability to optically scan living tissues along their depth. Aim of this study is the in vivo assessment at microscopic resolution of dental surfaces affected by EDs without resorting to invasive methods such as teeth extractions, to define histological findings occurring in chromatic and/or structural EDs. For the purpose, 15 children, referring at the Dental Clinic of the Second University of Naples, affected by several degrees of EDs, were enrolled and underwent in vivo RCM imaging to microscopically define the ED confocal features using a commercially available hand-held reflectance confocal microscope with neither injuries nor discomfort. Totally, 29 teeth were imaged. Results demonstrated images good in quality and the capability to detect EDs such as unevenness, grooves, and lack of mineralization according to their clinical degree of disarray. The present in vivo microscopic study on EDs allowed to highlight structural changes in dental enamel at microscopic resolution in real-time and in a non-invasive way, with no need for extraction or processing the samples. Further experiments could define the responsiveness to remineralizing procedures as therapeutic treatments.

In vivo imaging of enamel by reflectance confocal microscopy (RCM): non-invasive analysis of dental surface.

The aim is to establish the feasibility to image in vivo microscopic dental surface by non-invasive, real-time, en face Reflectance Confocal Microscopy (RCM). Fifteen healthy volunteers referred at the Multidisciplinary Department of Medical-Surgical and Odontostomatological Specialties, Second University of Naples, Naples, Italy, were enrolled. A commercially available hand-held RCM (Vivascope(®)3000, Lucid, Rochester, NY, USA) was used to image in vivo the dental surface of the upper right and left central incisors of each volunteer. Totally, thirty vestibular surfaces of upper central incisors were imaged in vivo by RCM to preliminary image the dental surface and assess the feasibility of a more extended study on teeth. In vivo RCM was able to image the dental surface within the enamel, at a maximum depth imaging of 300 µm, with images good in quality and the capability to detect enamel structures such as enamel lamellae and enamel damages, such as unevenness and cracks. In conclusion, enamel "optical biopsy", gained by RCM imaging, revealed to be a non-invasive real-time tool valid to obtain architectural details of the dental surface with no need for extraction or processing the samples. RCM appears to be an optimum auxiliary device for investigating the architectural pattern of superficial enamel, therefore inviting further experiments aimed to define our knowledge about damages after etching treatments or bracket removal and the responsiveness to fluoride seals and the morphology of the tooth/restoration interface. Moreover, this device could also be used to detect relevant diseases like caries, or to assess surface properties to evaluate lesion activity.

AI in Radiology: Navigating Medical Responsibility.

The application of Artificial Intelligence (AI) facilitates medical activities by automating routine tasks for healthcare professionals. AI augments but does not replace human decision-making, thus complicating the process of addressing legal responsibility. This study investigates the legal challenges associated with the medical use of AI in radiology, analyzing relevant case law and literature, with a specific focus on professional liability attribution. In the case of an error, the primary responsibility remains with the physician, with possible shared liability with developers according to the framework of medical device liability. If there is disagreement with the AI's findings, the physician must not only pursue but also justify their choices according to prevailing professional standards. Regulations must balance the autonomy of AI systems with the need for responsible clinical practice. Effective use of AI-generated evaluations requires knowledge of data dynamics and metrics like sensitivity and specificity, even without a clear understanding of the underlying algorithms: the opacity (referred to as the "black box phenomenon") of certain systems raises concerns about the interpretation and actual usability of results for both physicians and patients. AI is redefining healthcare, underscoring the imperative for robust liability frameworks, meticulous updates of systems, and transparent patient communication regarding AI involvement.

The Role of Artificial Intelligence and Texture Analysis in Interventional Radiological Treatments of Liver Masses: A Narrative Review.

Liver lesions, including both benign and malignant tumors, pose significant challenges in interventional radiological treatment planning and prognostication. The emerging field of artificial intelligence (AI) and its integration with texture analysis techniques have shown promising potential in predicting treatment outcomes, enhancing precision, and aiding clinical decision-making. This comprehensive review aims to summarize the current state-of-the-art research on the application of AI and texture analysis in determining treatment response, recurrence rates, and overall survival outcomes for patients undergoing interventional radiological treatment for liver lesions. Furthermore, the review addresses the challenges associated with the implementation of AI and texture analysis in clinical practice, including data acquisition, standardization of imaging protocols, and model validation. Future directions and potential advancements in this field are discussed. Integration of multi-modal imaging data, incorporation of genomics and clinical data, and the development of predictive models with enhanced interpretability are proposed as potential avenues for further research. In conclusion, the application of AI and texture analysis in predicting outcomes of interventional radiological treatment for liver lesions shows great promise in augmenting clinical decision-making and improving patient care. By leveraging these technologies, clinicians can potentially enhance treatment planning, optimize intervention strategies, and ultimately improve patient outcomes in the management of liver lesions.

Periodontitis in Psoriatic Patients: Epidemiological Insights and Putative Etiopathogenic Links.

Psoriasis, a systemic autoimmune disorder primarily affecting the skin, manifests through erythematous plaques and scales, impacting approximately 2-3% of the global population. Chronic periodontitis, a prevalent oral disease characterized by the destruction of tooth-supporting tissues, affects roughly 10-15% of adults worldwide. Emerging evidence suggests a bidirectional relationship between psoriasis and chronic periodontitis, supported by epidemiological studies indicating a higher prevalence of periodontitis among individuals with psoriasis and vice versa. Both conditions are chronic inflammatory diseases marked by dysregulated immune responses and altered cytokine profiles, notably involving proinflammatory cytokines such as TNF-α and IL-17. Clinical studies highlight a reciprocal impact of treating one condition on the other, underscoring the necessity of interdisciplinary collaboration between dermatologists and periodontists in managing patients with both conditions. This narrative review provides a comprehensive overview of the relationship between psoriasis and chronic periodontitis, examining epidemiological associations, shared inflammatory pathways, genetic insights, microbial dysbiosis, environmental factors, and clinical implications. The review emphasizes the importance of integrated care approaches and the potential for targeted therapeutic interventions to improve both psoriatic and periodontal patient outcomes, advocating for further research into the molecular and cellular mechanisms underpinning the comorbidity of these diseases.

In vivo characterization of healthy oral mucosa by reflectance confocal microscopy: a translational research for optical biopsy.

PURPOSE: To characterize in vivo microscopic features of healthy oral mucosa by noninvasive, real-time reflectance confocal microscopy (RCM). MATERIAL AND METHODS: One hundred healthy mucosal sites (38 lips, 24 cheeks, 10 gingivae, and 28 tongues) from 50 randomly selected volunteers were imaged by a commercially available in vivo RCM (Vivascope3000, Lucid, Rochester, NY). Morphological results were described and correlated with conventional histology. RESULTS: Specific microscopic parameters (cellular morphology, anatomical structures features, architectural patterns) were identified by RCM for each mucosal site. CONCLUSIONS: RCM features reproducibility in different mucosal sites and subjects, which suggests that RCM can be an adjunct tool for clinical management in stomatology.

Use of Probiotics for Oral Candidiasis: State of the Art and Perspective. A Further Step Toward Personalized Medicine?

Oral candidiasis is an opportunistic infection conventionally treated with antifungal drugs. However, the increasing number of fungal infections, parallel to the rising conditions sustained by non-albicans species, pose critical issues related to escalating drug resistances differently acquired by different species. Meanwhile, the knowledge of the interplay between oral microbiota and its host suggests alternative antifungal therapies based on the administration of probiotics. Probiotics are live microorganisms beneficial to the host, and literature reports consistent evidence for their use to treat gut diseases. The present work aimed to overview the primary mechanisms through which probiotics act against Candida species and the current status of knowledge on their use in clinical practice, particularly concerning oral candidiasis.

COVID-19 and Related Vaccinations in Children: Pathogenic Aspects of Oral Lesions.

Various clinical manifestations of SARS-CoV-2 infections and adverse reactions to COVID-19 vaccination have been described in children. The present narrative review aimed to collect and synthesize reported findings on oral lesions detected in SARS-CoV-2-positive subjects following COVID-19 EMA-authorized and WHO Emergency Use Listing-approved vaccine administration in the pediatric population to detail their clinical features and highlight possible pathogenic aspects of those lesions based on current evidence. Few and incomplete reports were retrieved from the literature, probably because most lesions belonged to a broad spectrum of systemic diseases and syndromes and were nonspecific or inaccurately described. The most common oral lesions in pediatric SARS-CoV-2-positive patients were erosive-ulcerative lesions and macules/petechiae, primarily erythematous. In the context of COVID-19 vaccination, oral adverse reactions were rare and typically presented as erosive-ulcerative lesions, with EM-like or unspecified patterns. Future studies should investigate oral lesions in SARS-CoV-2-positive subjects and after COVID-19 vaccination in the pediatric population, taking into account viral variants and newly developed vaccines. Deeper insight into oral lesions detectable in pediatric SARS-CoV-2-positive subjects and after COVID-19 vaccination may increase clinicians' ability to improve multidisciplinary pediatric oral and general care.

Oral Candidiasis in Adult and Pediatric Patients with COVID-19.

Oral Candidiasis (OC) is an opportunistic fungal infection of the oral cavity, frequently reported under local and systemic predisposing circumstances. While the recurrence of OC HIV-infected subjects has been well described and reported, the association between oral candidiasis and the SARS-CoV-2 infection is a recent finding that still is worthy of further study. The present paper focuses on this novel association, reporting the incidence and prevalence of OC occurring during and after COVID-19 and the possible etiopathogenic mechanisms underlying the onset of OC in COVID-19 subjects. The work found that the immune inflammatory hypo reactions and immunosuppression found in children and adults with COVID-19 could favor the proliferation colonization of Candida species and the following infection. At the same time, poor oral hygiene and iatrogenic causes seem to be the main risk factors.

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. Conventionally, oral candidiasis eradication is done with the help of antifungal drugs. However, the growing phenomena of drug resistance and the increase in infections sustained by non-albicans species being less responsive to common antifungals have orientied researches towards the experimentation of alternative therapies. The present review considered the most promising alternative therapeutic proposals. The use of plant derivatives with phytotherapy is a promising option, such as probiotics, to rebalance the oral microbiota in case of dysbiosis. Finally, antimicrobial photodynamic therapy (aPDT), with highly selective fungicidal activity and free of side effects, is also being studied as a powerful alternative to drug administration. All these therapies are alternatives or supportive to the conventional treatment of recurrent and non-drug-responsive forms of oral candidiasis. However, further studies are needed to define the most active compounds, the efficacy of the therapies compared with the conventional ones, and the planning of regulated and standardized protocols.

Antibiotics in Dentistry: A Narrative Review of the Evidence beyond the Myth.

Antibiotics have undoubtedly revolutionized medicine and the health and survival of patients with life-threatening infections, being nonetheless free from potential adverse effects, and the risk of intestinal dysbiosis, antimicrobial resistance, and the resulting consequences for the patient's health and the public purse. The present study narratively reviewed the epidemiological data on worldwide antibiotic consumption and administration in dental practice, patients' adherence to prescriptions, the antimicrobial resistance phenomenon in dentistry, and the evidence supporting and recommending appropriate antibiotic use in dental care. Eligible systematic reviews and original studies in humans published in the English language from January 2000 to 26 January 2023 were considered. A total of 78 studies, 47 on the epidemiology of antibiotic use and prescription in dentistry, 6 on antibiotic therapy in dentistry, 12 on antibiotic prophylaxis in dentistry, 0 on adherence of dental patients to antibiotic prescription, and 13 on antimicrobial resistance in dentistry, were presently considered. Retrieved evidence revealed that antibiotics are frequently overused and misused in dental practice, dental patients frequently do not adhere to prescriptions, and antimicrobial resistance in dentistry is a still rising phenomenon also secondary to improper oral antiseptics use. The present findings highlighted the need to establish more evidence-based and accurate antibiotic prescriptions to sensitize dentists and dental patients to minimize and rationalize the use of antibiotics only when it is indicated and necessary, improve patients' adherence, and enhance knowledge and awareness of the antimicrobial resistance in dentistry.

An Unconventional Oral Candidiasis in an Immunocompetent Patient.

Oral candidiasis (OC) is an opportunistic fungal infection of the oral mucosae, sustained by Candida albicans or other non-albican Candida 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. C. lusitaniae is an opportunistic strain that is rarely responsible for human infection and occurs mainly in severe immunocompromised states. The present work reported an unconventional case of OC in an otherwise healthy immunocompetent woman sustained by C. lusitaniae and a multi-resistant strain of C. albicans.
