Objective: This study assesses the associations between dendritic cells, HPV 6 and 11, and Recurrent Respiratory Papillomatosis (RRP) aggressiveness. Methods: The Derkay score was calculated using information obtained from the medical records. Biopsies from 36 patients with juvenile RRP (JRRP) and 43 adult RRP (ARRP) patients were analyzed under li...
A patient with an odontogenic fibroma (OF) with the presence of fibroblasts of varying morphology is presented, and the main microscopic differential diagnosis is discussed. Case report: a 51-year-old man complained of a swelling in the anterior region of the mandible. The panoramic radiograph showed a radiolucent, well-defined multilocular image,...
The aim of this study is to investigate the role of RASSF1A and KRAS protein immunoexpression in Oral Leukoplakia with Epithelial Dysplasia (OLD) and in Oral Squamous Cell Carcinoma (OSCC). Immunohistochemical staining for RASSF1A and KRAS was performed and a semiquantitative analysis was applied to samples of the Control Group (CG, n=20), OLD (n=3...
Human papillomavirus (HPV) types 6 and 11 are the etiological agents of recurrent respiratory papillomatosis (RRP). We examined the prevalence and distribution of HPVs 6 and 11 genetic variants in juvenile onset (JORRP) and adult onset (AORRP) laryngeal papillomas. Cases of JORRP and AORRP were collected, retrospectively. HPV detection and genotypi...
Objective: The aim of this study was to perform an epidemiologic, clinical, microscopic, immunohistochemical, and human papillomavirus (HPV) genotypical characterization of laryngeal papillomatosis (LP) and associate its results to the Derkay anatomic score. Study Design: A total of 36 samples of the juvenile group (JLP) and 56 samples of the adult...
This theoretical essay aims to point out the main contributions in the health and workers' safety aspects, considering the laws, public policies, international recommendations, and point out possible paths and roles of Occupational Therapy to fight against COVID-19 Brazilian pandemic. The literature shows that health care workers have three times m...
We report a case of atypical oral hairy leukoplakia (OHL) in a 9‐year‐old immunocompetent girl treated with fluticasone propionate nasal spray for allergic rhinitis. The OHL in childhood is uncommon and should be included in a differential diagnosis of white lesions in the oral mucosa.
Este ensaio teórico tem o objetivo de apontar as principais contribuições no âmbito da saúde e segurança do trabalhador ao enfrentamento da COVID-19, baseando-se em leis, políticas, normas e recomendações internacionais, de forma a apontar caminhos possíveis com relação às atuações em Terapia Ocupacional na saúde do trabalhador e no combate à pande...
Objective:
The objective was to investigate the prevalence of the Epstein-Barr virus (EBV) and its association with human papilloma virus (HPV) detection, clinicopathological features, and the severity of recurrent respiratory papillomatosis (RRP).
Methods:
Cases of juvenile recurrent respiratory papillomatosis (JRRP) (n = 36) and adult recurren...
p>Odontogenic lesions comprise a diverse group of lesions which usually affect the oral cavity and are derived from embryonic dental tissues. Their mechanisms of development and progression are still not fully known, but there are some studies investigating the participation of specific proteins in these events. Objective: The objective of this stu...
Objective:
The aim of this study was to investigate alterations in the EGFR gene and its protein expression for a better understanding of the biologic behavior of ameloblastoma.
Study design:
Twenty-five samples of ameloblastoma were selected, and dual-color fluorescence in situ hybridization assay was performed. The results of the assay and imm...
Intravascular papillary endothelial hyperplasia (IPEH) is an unusual benign, non-neoplastic vascular lesion that usually occurs in skin, but is uncommon in the oral cavity. Herein, we review the pertinent literature of oraiiPEH and report a new mixed form. A 61-year- old man presented with an ulcerated nodule in the lingual portion of the gingiva r...
The aim of this study was to investigate epidermal growth factor receptor (EGFR) gene alterations in two groups of patients with oral squamous cell carcinoma (OSCC) (a test group of subjects aged ≤40 years and a control group of subjects aged ≥50 years) and to associate the results with EGFR immunostaining, clinicopathological features, and the pro...
Oral potentially malignant disorders (OPMD) may develop malignant characteristics and transform into oral squamous cell carcinoma (OSCC) in a range of 1% to 2% of cases. Chronic alcohol consumption is associated with carcinogenesis, but its mechanism has not yet been fully elucidated. ALDH1A1 and 2, isoenzymes responsible for aldehyde oxidation inv...
p>Warfarin is an anticoagulant used to prevent thrombosis, cardiac arrhythmias, atrial fibrillation, and recurrence of pulmonary embolism. A 69-year-old male patient reported episodes of four heart attacks, stroke, pulmonary emphysema, varicose veins, thyroid dysfunction, and a history of angioplasty. They use daily dose of 5 mg. Intraoral clinical...
Objectives
The aim of this study was to evaluate three histologic grading methods for squamous cell carcinoma (SCC) of the lip, the conventional three-grade model proposed by the World Health Organization, tumor budding and depth of invasion (BD) model, and histologic risk assessment (HRA) model, and to correlate them with prognosis. Materials and...
Cystic odontoma is a rare entity, which is characterized by the association of a cyst with complex/compound odontoma. The aim of this study was to report the case of a 5-year-old male patient diagnosed previously with Hodgkin’s lymphoma and treated successfully with chemotherapy and radiotherapy, who developed a mandibular odontogenic lesion. Physi...
Objective:
The aim of this study is to report 2 cases of melanotic neuroectodermal tumor of infancy (MNTI), emphasizing the analysis of intratumoral immune cells by immunohistochemistry.
Study design:
Case 1: A 6-month-old girl presented with a 3-cm tumor in the anterior region of the left maxilla. Case 2: A 4-month-old boy presented with a 4-cm...
