Developing a core outcome set for anthropometric evaluation for presurgical infant orthopaedics for unilateral cleft lip and palate: e-Delphi consensus.

Introduction: Presurgical infant orthopaedics (PSIO) in infants with cleft lip and palate focuses on improving the anatomical conditions of the lip, palate and nose before the first lip surgery; however, its effectiveness has not been proven.

Objective: To develop a core outcome set for reporting anthropometry-based outcomes in studies appraising the PSIO before primary cleft lip repair in unilateral cleft lip palate (UCLP).

Method: Literature search to identify anthropometric measures.

Multiple approaches to oral epithelial dysplasia degree analyses: a pilot study.

Background: Oral epithelial dysplasia (OED) is the presence of cells of an abnormal type within a tissue, which may signify a stage preceding the development of cancer. Our aim was to determine the interrelation between the expression of multiple molecular markers and the histological features of oral dysplasia.

Methods: Fifteen samples of OED (five for each severity degree) were analyzed through software assisted image cytometry nuclear morphology.

Epstein-Barr virus-positive ulcer in the oral cavity.

Epstein-Barr virus-positive ulcer (EBV + U) is a recently reported B cell lymphoproliferative disorder in the oral cavity, oropharynx, gastrointestinal tract and skin, principally in immunosuppressed patients. A 53-year-old female patient with rheumatoid arthritis treated with methotrexate, presenting ulcers of unknown duration on the dorsum and the lateral left border of the tongue. Excisional biopsy, histopathological analysis and histochemical stains for syphilis (Warthin-Starry), mycotic diseases (Grocott silver methenamine), tuberculosis (Ziehl-Neelsen), immunohistochemistry tests for herpesvirus type 8 (CMV), EBV (LMP-1) and DNA extraction for polymerase chain reaction (PCR) assay to CMV, EBV and herpes simplex virus-1 were performed.

Overexpression and extra-mitochondrial localization of the chaperonin Hsp60 in ameloblastoma.

Objectives: Ameloblastoma is an odontogenic neoplasm of the mandible and maxilla with various histological types and subtypes. It has been reported that some ameloblastomas could arise from dentigerous cyst walls; thus, the development of ameloblastoma from dentigerous cysts may be due to differential protein expression. Our aim was to identify a membrane protein that is differentially expressed in ameloblastomas with respect to dentigerous cysts.

[Effect of the management of class I obesity with metformin on metalloproteinase activity in patients with chronic periodontitis].

Introduction: in Mexico the main problem in public health is obesity and other diseases that are associated whit this condition, including oral health. Objective: to evaluate the effect of metformin treatment in patients with class I obese on the activity of metalloproteinases present in periodontium with chronic periodontitis. Methods: a clinical study was conducted in 68 patients with class I obesity and periodontal disease.

Ectodermal and ectomesenchymal marker expression in primary cell lines of complex and compound odontomas: a pilot study.

Background: Odontomas are odontogenic tumors with hamartoma features that are classified as compound or complex. Our objective was to characterize the proliferation of ectodermal and ectomesenchymal profile markers of primary cell cultures of complex and compound odontomas.
