Human Papillomavirus 16 and 18 Infection in Oral Cancer in Thailand: A Multicenter Study.

Objectives: To identify the prevalence of high-risk human papillomavirus (HPV) genotypes 16 and 18 among patients with oral squamous cell carcinoma (OSCC) in Thailand and investigate the associations of p16 expression and HPV16/18 with the demographic, clinicopathologic, and risk parameters.

Materials And Methods: A total of 403 formalin-fixed paraffin-embedded OSCC specimens from four centers in four regions were obtained. p16 expression was evaluated by immunohistochemistry.

A Multicenter Study of Tongue Lesions from Thailand.

Objective: Tongue lesions constitute a considerable proportion of the oral lesions. Previous studies on tongue lesions were based on clinical studies. There has been a scarcity of the studies which are based on histopathological examination.

Cholesterol crystals in periapical lesions of root filled teeth.

Aim: To determine the prevalence of cholesterol crystals in periapical biopsies and to evaluate the correlation between cholesterol crystals in periapical biopsies and age, gender, location of the periapical lesion, pathologic diagnosis and lesion size.

Methodology: The biopsy report database (Faculty of Dentistry, Chulalongkorn University, Bangkok, Thailand) during 2005-2014 was reviewed. The prevalence of cholesterol crystals in the periapical lesions of root filled teeth was determined.

Oral cancer: A multicenter study.

Background: To determine the prevalence and clinicopathologic features of the oral cancer patients.

Material And Methods: Biopsy records of the participating institutions were reviewed for oral cancer cases diagnosed from 2005 to 2014. Demographic data and site of the lesions were collected.

Expression of C-X-C motif chemokine receptors 4 and 7 in salivary gland neoplasms.

Objectives: Chemokine receptors have been shown to overexpress in several cancer types. Binding of chemokines to their cognate chemokine receptors on tumor cells can promote tumor growth, angiogenesis and metastasis. The purposes of this study was to examine the expression of chemokine receptors, CXCR4 and CXCR7, in salivary gland neoplasms and its association with pathologic characteristics.

Ewing's Sarcoma of the maxillofacial region: A case report.

Ewing's sarcoma (ES) is an uncommon malignancy, especially in the head and neck region, with only 30 cases reported so far. The mandible is more affected than the maxilla. It represents the most frequent small round cell bone tumor of childhood and adolescence.

Dentofacial Deformity Caused by Bulky Osteochondroma: Report of an Unusual Case and the Importance of Cone Beam Computed Tomography.

Introduction: Osteochondroma of mandibular condyle is a rare benign tumor.

Case Report: This case report described clinical, radiographic features, differential diagnosis, histopathologic correlation and treatment of condylar osteochondroma.

Conclusion: Conebeam computed tomography (CBCT) is an alternative modality to CT or MRI that should be performed in all cases of suspected osteochondroma of the mandibular condyle.

A multicenter study of oral malignant tumors from Thailand.

Background: Oral malignant tumors in Thailand have not been extensively studied. Hence the following study was conducted.

Aims: To determine the prevalence and clinicopathologic data of the oral malignant tumors from Thailand.

Lower eyelid complications associated with transconjunctival versus subciliary approaches to orbital floor fractures.

Purpose: The aim of this study was to compare the frequencies of lower eyelid complications after subciliary versus transconjunctival approaches to orbital floor fractures.

Materials And Methods: The investigators implemented a retrospective cohort study and enrolled a sample composed of subjects who had orbital floor repair. The predictor variable was surgical approach, classified as subciliary or transconjunctival.

Factors associated with postrhinoplasty mucous cyst in cleft lip patients.

Purpose: The purpose of this study was to identify risk factors associated with postrhinoplasty mucous cyst (PMC) among adult cleft patients undergoing rhinoplasty. PMC has been reported sporadically in the literature. Its aetiology is uncertain.

Columellar flap for secondary cleft rhinoplasty with esthetic improvement of Millard's unilateral cheiloplasty scar.

Introduction: Columellar cartilage graft helps improve esthetic results in secondary cleft rhinoplasty for patients presenting with cleft lips. However, inadequate skin coverage of the cartilaginous graft can result in columellar necrosis and graft loss. Moreover, the scar after Millard's primary cheiloplasty may not be esthetic.
