Panitumumab has been more commonly associated with skin toxicity; oral adverse events have been scarcely reported in the literature. Herein, we present a case report of panitumumab-associated aphthous-like stomatitis.Methods: A 58 years old female visited the Oral Oncology Unit complaining of severe oral pain. The patient had been diagnosed with colon cancer metastatic to the liver and was receiving panitumumab (every 14 days) concurrently with irinotecan and 5-fluorouracil.Results: Clinical examination revealed multiple aphthous-like ulcers on the ventral surface and lateral borders of the tongue, lower lip and mucolabial fold, buccal mucosa and soft palate. Dexamethasone oral solution 0.5 mg/5 ml was topically administered t.i.d. along with tramadol 50 mg per os t.i.d. for pain management. One week later, the pain was relieved and the ulcers were almost completely healed. Tramadol administration was discontinued and dexamethasone was tapered during the following 8 days. There was no need for discontinuation of panitumumab. In close follow-up for the next four months, no painful oral symptomatology was reported.Conclusions: Anti-epithelial growth factor receptor agents are associated with oral adverse events that may cause severe pain, even necessitating discontinuation of the antineoplastic treatment. The implementation of preventive measures, early diagnosis, proper treatment and close monitoring of patients receiving anti-epithelial growth factor receptor agents are mandatory in order to preserve patients' quality of life and their compliance to therapeutic regimen.","PeriodicalId":53254,"journal":{"name":"eJournal of Oral Maxillofacial Research","volume":"15 4","pages":"e5"},"PeriodicalIF":1.0,"publicationDate":"2024-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11863649/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143525248","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The research covered the period from January 1, 2019 and July 1, 2024, included studies written in English, conducted in humans.Results: The results showed that hyperthyroidism can be associated with a higher prevalence of periodontitis due to decreased oral microbiome diversity, serum thyroid-stimulating hormone levels, increased periodontal pocket depth, clinical attachment loss and interleukin-6. Hyperparathyroidism after parathyroidectomy may lead to a slightly higher risk of tooth extraction in the first two years afterward because decreasing lamina dura, increasing periodontal ligament width. And hypothyroidism negatively affects the homeostasis of calcium and phosphorus in the oral fluid and can change the composition of bone minerals.Conclusions: Hyperthyroidism increases the risk of periodontitis by promoting deeper periodontal pockets, reducing oral microbiome diversity, altering alveolar bone structure and elevating inflammatory markers like interleukin-6, which are linked to disease progression. Hypothyroidism worsens periodontal disease by disrupting calcium-phosphorus balance and causing alveolar bone changes, especially in young individuals. Both conditions affect periodontal homeostasis, emphasizing the bidirectional relationship between endocrine and periodontal health. Dentists should monitor thyroid dysfunction, as managing thyroid levels may improve periodontal treatment.","PeriodicalId":53254,"journal":{"name":"eJournal of Oral Maxillofacial Research","volume":"15 4","pages":"e1"},"PeriodicalIF":1.0,"publicationDate":"2024-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11863652/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143525245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Relevant data from 37 studies, including study characteristics, patient population, test details, and outcomes, were systematically extracted. The search was performed analysing studies across multiple electronic databases including MEDLINE (PubMed), Embase, Scopus and Google Scholar, published from January 15, 2024 until May 15, 2024. Risk of bias was assessed using a modified QUADAS-2 tool.Results: Most studies demonstrated a low risk of bias in most domains, indicating overall methodological rigor. Comparative analysis showed that direct immunofluorescence (DIF) consistently outperformed indirect immunofluorescence. DIF exhibited high sensitivity and specificity for pemphigus vulgaris (87.8% and 100%), mucous membrane pemphigoid (92% and 98%), and desquamative gingivitis oral ulcers overlapping with oral lichen planus (OLP) (81% and 98.9%). For OLP, DIF showed moderate sensitivity (64.3%) and high specificity (88%).Conclusions: This review highlights the superior diagnostic utility of direct immunofluorescence over indirect immunofluorescence in evaluating oral lesions. Direct immunofluorescence's higher performance makes it the preferred technique for conditions requiring direct visualization of tissue-bound immune deposits. The combined use of direct immunofluorescence and indirect immunofluorescence can enhance the evaluation and management of various oral pathologies.","PeriodicalId":53254,"journal":{"name":"eJournal of Oral Maxillofacial Research","volume":"15 3","pages":"e2"},"PeriodicalIF":1.0,"publicationDate":"2024-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11574967/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142683441","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Type I collagen was analysed by immunohistochemistry, Fisher's exact test and chi-square test evaluated the clinical data. One-way ANOVA and Tukey's test were applied to analyse type I collagen expression between groups. Associations between data were analysed by two-way ANOVA with Sidak's multiple comparison test.Results: Men were most affected with OSCC (90%) and 60% of OL were in women (P = 0.0022). Type I collagen expression was higher in mild (P = 0.04) and moderate (P = 0.03) OED than moderately differentiated OSCC.

No significant differences in age, gender, and BMI were found between the groups. For the acoustic rhinometry measurements significantly increased resistance (P = 0.04), reduced volume (P = 0.03) and distance to minimal cross-section area (MCA) (P = 0.035) were found in the study group, but only for the right nostril. However, significantly reduced MCA for both nostrils was found in the study group (P = 0.025 to 0.04). No significant differences in acoustic pharyngometry measurements were found.Conclusions: Nasal airway dimensions were significantly reduced, and nasal resistance was significantly increased in the study group compared to controls. Thus, class II and large overjet with indication for growth adaptive treatment may be a risk factor for sleep-disordered breathing. In the future, orthodontic paediatric patients may benefit from non-invasive risk assessment of narrow upper airway using acoustic reflection.","PeriodicalId":53254,"journal":{"name":"eJournal of Oral Maxillofacial Research","volume":"15 3","pages":"e5"},"PeriodicalIF":1.0,"publicationDate":"2024-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11574966/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142683557","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
