1/4. Plasma cell mucositis: a review and case report.The simultaneous involvement of the mucous membranes of the oral cavity and upper aerodigestive tract by lesions characterised clinically by an intensely erythematous, lobulated surface and histologically by a dense connective tissue infiltrate composed of non-neoplastic plasma cells may be called plasma cell mucositis. We present a review of the literature, consisting of 14 cases, outlining the multifocal site distribution, chronicity and systemic background that distinguish this entity and report a single case with confirmation of the polyclonal nature of the plasma cell infiltrate using gene rearrangement studies.- - - - - - - - - - ranking = 1keywords = oral cavity (Clic here for more details about this article) |
2/4. Gastro-omental free flaps in oral and oropharyngeal reconstruction:surgical anatomy, complications, outcomes.Free gastro-omental flaps can be used to reconstruct defects in the oral cavity after ablative cancer surgery. The omentum can provide as much bulk as required. The generous gastro-omental pedicle allows mobility. The gastric mucosal lining has the advantage that it produces mucus, does not carry hair follicles and is not prone to troublesome desquamation. This paper reviews the surgical anatomy of free gastro-omental flaps and presents a series of eight cases in which these flaps were used for oral and oropharyngeal reconstruction.- - - - - - - - - - ranking = 1keywords = oral cavity (Clic here for more details about this article) |
3/4. Atypical supraglottitis caused by streptococcus sanguis.A case of atypical supraglottitis in an 11-year-old boy is presented. The epiglottis was only mildly inflamed. The organism isolated from blood culture was streptococcus sanguis. This organism is a normal commensal of the oral cavity and has not previously been reported as a cause of supraglottitis.- - - - - - - - - - ranking = 1keywords = oral cavity (Clic here for more details about this article) |
4/4. calcium oxalate is the main toxic component in clinical presentations of alocasis macrorrhiza (L) Schott and Endl poisonings.alocasia macrorrhiza (L) Schott and Endl is called Hai Yu, Tien Ho, Shan Yu, Kuan Yin Lien, Tu Chiao lien, Lao Hu Yu and Lang Du in Chinese. Its common English name is Giant Elephant's Ear. The toxic effects of A macrorrhiza arise from sapotoxin and include gastroenteritis and paralysis of the nerve centers. From 1985 to 1993 all individuals who called the Poison Control Center asking for information regarding macrorrhiza were included in this retrospective study. A questionnaire filled out by the Poison Control Center staff collected the demographic data of the victim, the reason for consumption, the prescribed part, clinical symptoms and signs of the victim, and medical outcome of poisonings. Among 27 cases of A macrorrhiza poisoning, the age was 1.5 to 68 y with 12 females and 15 males. One had skin contact and 1 had eye contact. In the 25 cases that consumed the plant leaf or tuber either raw or cooked, the primary symptom was in injected sore throat and the secondary symptom was numbness of the oral cavity. Some patients had salivation, dysphonia, abdominal pain, ulcers of the oral cavity, difficulty in swallowing, thoracodynia, chest tightness and swollen lips. We believe the presence of sapotoxin alone is not sufficient to explain the injected swollen and ulcerative lesions. calcium oxalate is reported distributed in the entire plant and results in inflammation of the oral cavity and mucous membranes just as our patients had.- - - - - - - - - - ranking = 3keywords = oral cavity (Clic here for more details about this article) |
