Oral manifestations of delusional infestation: a case series.

BACKGROUND: Delusional infestation (DI) is a rare psychotic disorder characterized by a patient's false belief that the body is infested with living or non-living organisms in the absence of clinical evidence of disease. Based on the underlying etiology, DI can be classified into primary and secondary forms based on the presence or absence of an underlying condition or previously diagnosed psychiatric disorder. This paper discusses a condition that is not commonly reported in the literature. CASE PRESENTATION: Here, we describe four patients diagnosed with DI of the oral cavity. In each case, the patients' intraoral examinations revealed either traumatic lesions or no signs of mucosal disease. Management involved symptom management, medical therapy, and/or a referral to the primary care provider. CONCLUSION: Because oral health care providers may encounter patients with DI, they should familiarize themselves with this unusual condition in order to recognize the condition and initiate prompt referral to a psychiatrist.

Assessing the knowledge and awareness of US oncologists regarding the specialty of oral medicine.

OBJECTIVES: This cross-sectional study aimed to assess the awareness among United States (US) oncologists about oral medicine (OM) as a specialty of dentistry, and their collaboration with OM providers. METHODS: An online survey was conducted, inviting 1350 US oncologists, with data collected on demographics, practice background, comfort level with diagnosing and treating oral conditions, referral practices for oral conditions, and more. RESULTS: Of the invited 1350 oncologists, 192 responded (14% response rate). Among respondents, 46% were familiar with the OM specialty. Of these, 73% had previously sought consultation from OM specialists. The primary reasons for referral included dental clearance before initiating chemotherapy (38.5%), dental clearance before initiating radiotherapy (37%), and managing oral ulcers and oral potentially malignant disorders equally (32.2%). Regarding referrals to providers outside of OM, oncologists primarily referred patients with oral lesions to otolaryngologists (64.6%), followed by oral and maxillofacial surgeons (55.2%) and general dentists (45.3%). CONCLUSION: Our study showed that over half of US oncologists were unfamiliar with the OM specialty. However, the referral rate to OM providers was high among oncologists who had prior OM knowledge. It is advisable to enhance the collaboration between OM and oncology specialists to ensure optimal care for patients with cancer.

A Bibliometric analysis of scientific publication on Peri-Implantitis from 1990 to 2020.

Background: Peri-implantitis can involve about 13% of implants and 20% of patients, it has been reported that its incidence increases from about 0.4 to 43.9% in 3-5 years. The purpose was to analyze, using bibliometric indicators, the scientific efficiency of different organization, countries, and researchers that published articles on Peri-implantitis in various dental journals during the period from 1990 to 2020. Material and Methods: The search was carried out using Scopus database on publications related to Peri-implantitis from 1990 to 2020 using VOSviewer 1.6.15. The selected search encompassed title of article, citation count, year of publication, authors, institution, country and keywords. Data maps were obtained from VOS viewer based on number of papers, citation count, sources, countries and authors. A density visualization analysis was performed to interpret the data. Bibliometric analysis with reference to citation and documents, authors, journals and keywords was also evaluated. Results: An upsurge in number of cumulative papers published on Peri-implantitis from 1990 to 2020 was observed. The top three countries that published most research papers on Peri-implantitis included United States, Sweden and Switzerland respectively. The most productive organization in the field was Blekinge Institute of Technology, Karlskrona, Sweden. The maximum numbers of papers were published in "Clinical Oral Implants Research", while the most published and cited author was Niklaus P. Lang, with 50 papers, 5391 citations with 107.82 average citations per paper. Conclusions: There is a tremendous increase in number of publications on peri-implantitis through collaboration of authors, nations and institutes. Among the leading countries from where evidence is originating includes, USA, Sweden and Switzerland. The leading institutes whose work received most citations included, Kristiansand University (Sweden), Blekinge Institute of Technology (Sweden), Trinity college (Dublin) and University Of Bern (Switzerland). A positive trend of highly collaborative work was observed among the institutes and authors on peri-implantitis. Key words:Bibliometric analysis, Peri-Implantitis, Scopus, Dental implants.
