Factors affecting the quality of life of patients with medication-related osteonecrosis of the jaw during treatment: A quality-of-life survey and causal analysis.

This prospective cohort study aimed to investigate the impact of medication-related osteonecrosis of the jaw (MRONJ) on health-related quality of life (HRQOL) and oral health-related QOL (OHRQOL) and the association between the downstaging of MRONJ and OHRQOL. The HRQOL and OHRQOL of 44 patients with MRONJ were assessed using the SF-36v2 and the General Oral Health Assessment Index (GOHAI), respectively. Treatment was performed in accordance with the AAOMS position paper (2014).

Giant peripheral ossifying fibroma with coincidental squamous cell carcinoma: a case report.

Background: Peripheral ossifying fibroma is an inflammatory or reactive hyperplasia of the gingiva that is usually small. It is formed by hard tissue in fibrous tissue, and the name "neoplastic lesion" has tended to be used frequently in Europe and America. Clinically, peripheral ossifying fibromas are painless, solitary, exophytic, sessile, or pedunculated and more frequently found in females than in males.

Bacterial Distribution and Community Structure in Beef Cattle Liver and Bile at Slaughter.

Abstract: In this study, the distribution of hygienic indicator bacteria in cattle livers and bile was examined at slaughterhouses. One hundred twenty-seven cattle livers with gallbladders were carefully eviscerated from carcasses at 10 slaughterhouses. Microbiological examination revealed that nine bile samples (7.

Clinical value of entire-circumferential intraoperative frozen section analysis for the complete resection of superficial squamous cell carcinoma of the tongue.

Objectives: We aimed to evaluate the clinical value of an entire-circumferential intraoperative frozen section analysis (e-IFSA) for the complete resection of superficial squamous cell carcinoma (SCC) of the tongue.

Materials And Methods: A total 276 specimens from 51 patients with pT1-2, N0, mucosal or submucosal invasion SCC were analyzed to evaluate the diagnostic accuracy of the e-IFSA and the added value of the e-IFSA to iodine staining. The e-IFSA results were compared with the final histologic results obtained using permanent sections.

Acute odontogenic infection combined with crowned dens syndrome: a case report.

Background: Calcium pyrophosphate dihydrate crystal deposition disease is a condition in which calcium pyrophosphate dihydrate crystal is deposited in joint cartilage and ligaments. Calcium pyrophosphate dihydrate crystal deposition disease that involves calcification around the odontoid process of the second cervical vertebra is called crowned dens syndrome. Crowned dens syndrome is accompanied by fever in addition to acute and intense neck, posterior head, and temporal pain; thus, distinguishing crowned dens syndrome may be difficult in the presence of odontogenic infection.

Desmoid-type fibromatosis of the head and neck in children: a case report and review of the literature.

Background: Desmoid-type fibromatosis is defined as an intermediate tumor that rarely occurs in the head and neck of children. There is no doubt as to the value of complete surgical excision for desmoid-type fibromatosis. However, in pediatric patients, surgeons may often be concerned about making a wide excision because of the potential for functional morbidity.

Development of a competition model for microbial growth in mixed culture.

A novel competition model for describing bacterial growth in mixed culture was developed in this study. Several model candidates were made with our logistic growth model that precisely describes the growth of a monoculture of bacteria. These candidates were then evaluated for the usefulness in describing growth of two competing species in mixed culture using Staphylococcus aureus, Escherichia coli, and Salmonella.
