Paroxysmal nocturnal hemoglobinuria (PNH) is a hematological disorder that affects hematopoietic stem cells. An association with other hematological diseases, such as hemolytic anemia and neutropenia, is observed with a high occurrence of aplastic anemia. The aim of the present study is to report a case of dental infection in a patient with PNH exhibiting exuberant gingival involvement. A 45‐year‐old male patient sought the Federal University of Ceara reporting severe toothache associated with tooth 24. Clinical examination revealed that the tooth was associated with an apparent fistula and a yellowish lesion with smooth surface located in the palate. The patient had interrupted the medication to control PNH. Blood transfusion was requested due to deficient hematological parameters. Tooth extraction and excisional biopsy were performed under antibiotic coverage. In the postoperative period, low‐level laser therapy (LLLT) was performed. Histopathological examination revealed connective tissue showing extensive necrotic areas, accumulation of basophilic material, numerous cyst‐like cavities, and degenerated cells. Histopathological findings were compatible with the initial clinical diagnosis of gingival necrosis. The patient evolved with febrile neutropenia, requiring hospitalization for 1 month. Improvement in the overall health was observed after the administration of antibiotics, eculizumab, and weekly LLLT at the biopsy site.
Background
Malignant neoplasms that affect children and adolescents are predominantly embryonic and generally affect blood system cells and supporting tissues.
Aim
This study aimed to summarize the scientific evidence about the prevalence of malignant lesions in the oral cavity of children and adolescents.
Design
In this systematic review and meta‐analysis (PROSPERO CRD42020158338), data were obtained from seven databases and the gray literature. Cross‐sectional observational studies on the prevalence of biopsied oral pediatric malignancies were included. The Newcastle‐Ottawa Scale assessed the quality of the included studies, and the GRADE approach evaluated the evidence certainty. The meta‐analysis prevalence was calculated using MedCalc® software, adopting a 95% confidence level (CI; random‐effect model).
Results
Forty‐two studies were included in the meta‐analysis. Of the 64,522 biopsies, the prevalence of malignant lesions was 1.93% (n = 1,100; 95% CI = 1.21%‐2.80%). Countries with a low socioeconomic profile showed the highest prevalence. The sample size did not influence the prevalence of oral malignancies, and unspecified lymphomas (12.08%; 95% CI = 5.73%‐20.37%) and rhabdomyosarcoma (10.53%; 95% CI = 7.28%‐14.30%) were the most common lesions.
Conclusions
Oral malignant lesions biopsied in children and adolescents had a prevalence of <3%, and lymphomas and sarcomas were the most prevalent lesions.
e24200 Background: The objective of this study was to evaluate anxiety and spirituality levels in oncology patients during the coronavirus disease 2019 (COVID-19) pandemic. Methods: This short-term cross-sectional study applied a previously validated General Anxiety Disorder-7 (GAD7) scale and spirituality inventory to 230 patients undergoing antineoplastic chemotherapy during the second wave of COVID-19 in Brazil. The means ± SD of the scales were calculated and correlated (Spearman's rho). After categorization, chi-square and multinomial regression models were used to identify risk factors (p < 0.05). Results: The levels of anxiety (6.16±5.11) and spirituality (17.22±2.66) were moderately and inversely correlated (p = 0.001, r = -0.212). Women (p = 0.025), fatigue (p = 0.048), and insomnia (p = 0.001) were associated with an increased incidence of anxiety; however, spirituality was associated with a reduced incidence of fatigue (p = 0.032). Death of family or friends due to COVID-19 increased the risk of high levels of anxiety (p < 0.05), while in multivariate analysis, insomnia (p = 0.030) and sleep difficulty (p = 0.031) were also directly associated with anxiety and spirituality reduced the interruption of chemotherapy during the COVID-19 pandemic (p = 0.036). Conclusions: Fear of the COVID-19 pandemic altered the psychoemotional environment of patients undergoing chemotherapy, resulting in increased levels of anxiety. However, spirituality was an important coping strategy in patients undergoing cancer treatment.
Salivary gland tumors account for only 3%–5% of all tumors in the head and neck, 10%–15% of which originate from minor salivary glands. Pleomorphic adenoma is a benign lesion of the salivary gland, most commonly occurring in the region of the hard and soft palates. The treatment of choice for pleomorphic adenomas is with the partial or total function of the extension of the lesion, and placing palatal obturators are one method of reestablishing masticatory function and facial esthetics. This study aimed to rehabilitate a patient using a palatal implant following partial maxillectomy for the removal of a pleomorphic adenoma. A young patient with pleomorphic adenoma of the hard palate underwent a partial right-sided maxillectomy procedure which removed the hard palate and alveolar regions of the molars. Prior to surgery, the patient was assessed to make a surgical guide for resection of the tumor, as well as a provisional obturator plate using orthodontic wire clasps. After healing, the patient was rehabilitated using a palatal obturator which had been incorporated into a removable partial denture. The clinical sequence used to fabricate the final prosthesis was as follows: initial molding after surgery, prosthesis design, preparation of the mouth, work molding, structure testing and orientation planning, teeth testing and installation, and periodic maintenance. Thus, we can conclude that the palatal obturator is an excellent means of restoring a patient’s oral function, facial esthetics, and overall quality of life.
