A significant increase in dental diseases in adolescents who spend a long time at the computer, according to modern concepts, is mediated by the electromagnetic field of the computer, the impact of which has not been fully studied. The paper presents data from a comparative study of the dental status of the oral cavity and the state of periodontal tissues in adolescents aged 18 to 15 who spend more than 5 (target group of 55 adolescents) and less than 5 hours (control group of 20 adolescents) at the computer. The selection of the contingent was carried out randomly. According to the dental characteristics of the oral cavity, the number of dental plaque was assessed according to the simplified Turkish OHI-S hygiene index, in the modification Hi Fedorov-Volotkina, the severity of inflammatory and destructive changes in periodontal tissues according to the Pi index (Russell), and their prevalence according to the Papillary-Marginal-Alveolar index PMA in Parma modification. The conducted comparative study showed that in adolescents who worked 8 - 12 hours at the computer, periodontal changes occur much more often and are more pronounced than in adolescents who worked less than 5 hours. In addition, the neurohormonal parameters of the saliva of adolescents who are at the computer for less than 5 hours practically do not change, but in adults who work longer than 8 hours the saliva data in the mouth changes while.

oral cavity cancers are part of head and neck cancers. They have become frequent in the world in general and Senegal in particular. This study evaluates microsatellite instability tumors in oral cavity cancers in Senegal. Forty cancerous tissues, 20 healthy tissues, and 12 blood tissues were included in this study. These tissues were collected from each patient during the biopsy after obtaining consent. DNA extraction, Polymerase Chain Reaction (PCR) and sequencing were carried out to obtain sequences. Mutation surveyor, Bioedit and Dnasp software were used to perform our analyses. High instability was found in 57.5% of patients with cancer. Moreover, 90% of the patients had the same motif on healthy and cancerous tissue. Furthermore, 26.12%, 20.72%, and 11.71% polymorphic sites were found in cancerous, healthy and blood tissue respectively. Thus, a similarity between cancerous and healthy tissues seems to exist. This implies that instability of the Bat 26 microsatellite could occur early in the occurrence of oral cavity cancers.

Cystic Lymphangioma on the Floor of the oral cavity Extending to the Submandibular Region in Adult Patients

引用

International Journal of Otolaryngology and Head & Neck Surgery 2020年第4期9卷 133-140页

作者： Nadia M’jahad Najib Benmansour Abdelouahid Taleuan Akammar Amal Mustapha Maaroufi Mohamed Nourredine El Alami Faculty of Medicine and Pharmacy Sidi Mohammed Benabdellah University Fez Morocco Department of Otorhinolaryngology (ENT) and Headneck Surgery CHU Hassan II Fez Morocco Department of Radiology CHU Hassan II Fez Morocco

Lymphatic malformation (ML), formerly called cystic lymphangioma is a benign hamartomatous tumor of lymphatic vessels. The onset of lymphangiomas is either at birth (60% to 70%) or up to two years of age (90%) and rare in adults. These malformations can occur in any region of the body, Lymphangiomas have marked predilection for the head and neck region (50% - 70%). The most common location in the mouth is the dorsum of tongue. If the positive diagnosis is generally easy, the therapeutic management remains controversial. We report the clinical case of a 23-year-old adult patient with cystic lymphangioma on the floor of the oral cavity extending gradually to the right submandibular region. The clinically suspected tumor was thoroughly explored using tomodensitometry. The treatment consisted of complete resection by a cervicotomy with histological examination confirming the macroscopic diagnosis of cystic lymphangioma. Follow-up at 3 years showed no recurrence.

Purpose: Candida albicans is regarded as a part of normal flora in the human oral cavity. However, it remains unclear whether the genus Candida, especially C. albicans, is an oral resident microorganism and causes marital infection or not. The purpose of the present study was to elucidate the origin of oral C. albicans by investigating the colonization and infection route to oral cavities of this organism with arbitrarily primed polymerase chain reaction (AP-PCR). Methods: After C. albicans was isolated from four subjects (average age: 42.2, range: 33 - 56), the isolations of this organism from them were performed six months later again. To investigate whether C. albicans is an oral resident microorganism, the genotype homology of each C. albicans isolates that were isolated twice from the same subjects was compared. Moreover, C. albicans was isolated from five pairs of married couples (average period of cohabitation: 12.4 years, range: 5 - 31). To investigate whether C. albicans causes marital infection, the genotype homology of C. albicans isolates that were isolated from each pair of married couples was compared. Results: AP-PCR patterns of C. albicans that were isolated from each subject at o month and after 6 months showed the identical genotypes among each individual. C. albicans isolates from five pairs of married couples showed the identical genotypes between a husband and wife of each pair on AP-PCR. Conclusion: These results indicated that C. albicans was an oral resident microorganism and caused the marital infection.

Determination of Fungal Colonization in the oral cavity of College Students

Journal of Life Sciences 2012年第10期6卷 1133-1141页

作者： Floridia Ricardo Rodriguez Graciela Ampuero Veronica Gonzalez Luis Department of Parasitology and Mycology National University of San Luis San Luis 5700 Argentina

In recent years, an increase in opportunistic fungal colonization in the oral cavity in immunocompetent patients （IC） has been observed. In the bibliography, the most observable genre is Candida and less frequently found are other opportunistic such as Aspergillus, Rhizopus, Cryptococcus, and others. The authors determined the presence of fungi in the oral cavity of IC students, and their relationship with the concentration of secretory IgA in saliva. To this end, we collected 50 samples of oral cavity swabs, which underwent direct examination and culture in Sabouraud dextrose agar with chloramphenicol. For its identification, CHROMagar Candida and API Candida （BioMerieux） were used. We obtained nine positive cultures （7 Candida albicans and 2 Saccharomyses cerevisiae）, which represented 18% of the studied population. Throughout radial immunodiffusion （RID plates-PLATE）, we determined the concentration of secretory IgA. No relationship was observed between the colonized group and group that was not colinized. The colonization rate found is below the one described in the bibliography （30% to 50%）. However, these opportunistic fungi cause transitory colonization with no clinical relevance in IC patients and, its percentage can vary according to the studied population.

International Journal of oral Science 2014年第3期6卷 185-187页

作者： Manal Abdulaziz Al Sheddi Ahmad Assari Hezekiah Mosadomi Department of oral Medicine and Diagnostic Sciences College of Dentistry King Saud University Department of oral and Maxillofacial Surgery and Diagnostic Sciences Riyadh Colleges of Dentistry and Pharmacy

Spindle cell lipoma（SCL） is a benign lipomatous neoplasm typically located in the posterior neck and back of older males. It presents as a well-circumscribed mass in the buccal mucosa, tongue, floor of the mouth or hard palate. There are only two case reports of SCL in the gingiva and alveolar ridge. Here, we report a case of SCL in the mandibular mucogingival junction of a 68-year-old male. Clinical,histopathological and immunohistochemical findings are presented. Although oral SCL is rare, it should be considered in the differential diagnosis of spindle cell neoplasms occurring in the oral cavity.

An association between Helicobacter pylori and upper respiratory tract disease: Fact or fiction?

引用

World Journal of Gastroenterology 2014年第6期20卷 1470-1484页

作者： Shin Kariya Mitsuhiro Okano Kazunori Nishizaki Department of Otolaryngology-Head and Neck Surgery Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences

Helicobacter pylori(H. pylori) is a major cause of chronic gastritis and gastric ulcers and considerable evidence supports the notion that infection with this bacterium is also associated with gastric malignancy in addition to various other conditions including pulmonary, vascular and autoimmune disorders. Gastric juice infected with H. pylori might play an important role in upper respiratory tract infection. Although direct and/or indirect mechanisms might be involved in the association between H. pylori and upper respiratory tract diseases, the etiological role of H. pylori in upper respiratory tract disorders has not yet been fully elucidated. Although various studies over the past two decades have suggested a relationship between H. pylori and upper respiratory tract diseases, the findings are inconsistent. The present overview describes the outcomes of recent investigations into the impact of H. pylori on upper respiratory tract and adjacent lesions.
