RESUMO
Background: The aim of the present study was to compare the recurrence rates of solid multicystic ameloblastomas after segmental resection or marginal resection. Material and Methods: PubMed, ScienceDirect, Web of Science, Scopus, Embase were searched for studies published up to July 2022. The gray literature was also searched. Meta-analysis was performed using OpenMeta Software, p< 0.05 considered significant. Results: Among the search, 8 studies met all eligibility criteria. The group that underwent marginal resection was 1.1 times more likely to present recurrence of the lesion compared to the group that underwent segmental resection. There was no statistically significant difference between the two groups (segmental resection and marginal resection) in all eight studies regarding reducing ND (95% Confidence interval, 0.339 - 3.705; heterogeneity: Q value= 3.105; I2= 0%). Conclusions: The results showed that there was no statistically significant difference between segmental and marginal resection for the treatment of solid multicystic ameloblastomas; however, prospective studies with more rigorous methodological procedures are needed to better compare the surgical techniques. Key words:Ameloblastoma, solid multicystic ameloblastoma, treatment, recurrence.
RESUMO
This systematic review aimed to analyze the clinicopathological profile and relevant prognostic factors of head and neck rhabdomyosarcoma in pediatric patients. The search was carried out in the electronic search portals PubMed, Lilacs, Embase, Scopus, and Web of Science. The search yielded studies that were then analyzed regarding study topic, data extraction, and risk of bias using the STROBE (Strengthening the Reporting of Observational Studies) guidelines. Finally, three studies were included for qualitative analysis. Most of the cases involved embryonic and alveolar rhabdomyosarcoma. Expression of MYOD1 was highly correlated with diagnosis of spindle cell/sclerosing rhabdomyosarcoma, which appears to have a poor prognosis in children. Furthermore, tumor size <5 cm and absence of metastasis accompanied by complete resection and administration of adjuvant therapies such as chemotherapy and radiotherapy favored a better prognosis.
RESUMO
A case of Burkitt's lymphoma with bilateral jaws involvement in a 5-year-old boy is reported discussing the dentist's role in the diagnosis and management of this disease. The initial clinical diagnosis established of maxillary swelling causing trismus was a dentoalveolar abscess. The incisional biopsy was performed and histopathological analysis, including immunohistochemistry, confirmed the Burkitt's lymphoma. The patient underwent treatment and remains free of the disease for 36 months of follow-up. The occurrence of intraoral bilateral jaws involvement of Burkitt's lymphoma in child is unusual and its accurate diagnosis avoids complications in the patient's treatment.
