1/7. Buccal mucosal cancer patient who failed to recover taste acuity after partial oral cavity irradiation.PURPOSE: We report a patient who suffered from prolonged loss of taste acuity after partial oral cavity irradiation. methods: The electric taste threshold (ETT) of each point in the oral cavity was measured with an electric gustometer to evaluate quantitative local taste acuity. A subjective total taste acuity (STTA) scale was used to evaluate subjective total taste acuity. CASE: A 61-year-old male patient with right buccal mucosal cancer underwent radiation therapy more than 11 years ago, and has suffered from loss of taste acuity since then. He received electron beam irradiation to part of the oral cavity and right upper neck, mainly the right buccal mucosa near the retromolar trigone and a metastatic right submandibular node. He did not receive irradiation to the anterior portion of the tongue or left side of the posterior portion of the tongue. His ETT scores for each point were equal to or greater than 26, and his STTA score was grade 3. CONCLUSION: The present case implies that radiation damage to part of the oral cavity can cause the loss of subjective total taste acuity.- - - - - - - - - - ranking = 1keywords = oral cavity, cavity (Clic here for more details about this article) |
2/7. Lexical-gustatory synaesthesia: linguistic and conceptual factors.This study documents an unusual case of developmental synaesthesia, in which speech sounds induce an involuntary sensation of taste that is subjectively located in the mouth. JIW shows a highly structured, non-random relationship between particular combinations of phonemes (rather than graphemes) and the resultant taste, and this is influenced by a number of fine-grained phonemic properties (e.g. allophony, phoneme ordering). The synaesthesia is not found for environmental sounds. The synaesthesia, in its current form, is likely to have originated during vocabulary acquisition, since it is guided by learned linguistic and conceptual knowledge. The phonemes that trigger a given taste tend to also appear in the name of the corresponding foodstuff (e.g. /I/, /n/ and /s/ can trigger a taste of mince /mIns/) and there is often a semantic association between the triggering word and taste (e.g. the word blue tastes "inky"). The results suggest that synaesthesia does not simply reflect innate connections from one perceptual system to another, but that it can be mediated and/or influenced by a symbolic/conceptual level of representation.- - - - - - - - - - ranking = 0.0086057713438249keywords = mouth (Clic here for more details about this article) |
3/7. Patterns of sensory recovery in the lingual nerve after surgical trauma.OBJECTIVE: To examine the pattern of sensory recovery in the lingual nerve following injury, with an emphasis on qualitative changes. methods: Using data from one patient with prolonged dysaesthesia after surgical trauma to the lingual nerve, we correlated changes in perceived sensory function during recovery with results from qualitative and quantitative taste tests, and patient-reported quality-of-life measures. RESULTS: Recovery of quantitative taste testing as measured by automated electrogustometry, and qualitative whole of mouth taste testing, preceded perceptual recovery of taste. On the other hand, taste acuity as measured by regional qualitative taste testing tended to lag behind perceptual recovery. The pattern of recovery in the different qualitative taste sensations suggests variation in sensitivity of the nerve fibres responsible for carrying taste sensation, with the fibres relating to bitter and sour taste being the last to recover. CONCLUSION: To our knowledge, taking into account the limitations of this study, this picture of differential recovery of taste function in the lingual nerve has not been previously reported.- - - - - - - - - - ranking = 0.0086057713438249keywords = mouth (Clic here for more details about this article) |
4/7. A decade-long sour-taste sensation successfully treated with a proton-pump inhibitor.We report a case study of a 54-year-old Japanese woman who persistently suffered from a sour-taste sensation in her mouth for 10 years, and was treated with a proton-pump inhibitor (PPI). She found sour-tasting meals irritable, and after eating such meals the sour-taste sensation worsened. She also complained of eructation and regurgitation. Upper gastrointestinal (GI) endoscopy showed duodenal erosion, superficial gastritis, and erosive oesophagitis. After 2 weeks of PPI therapy (lansoprazole, 30 mg day(-1)) the sour taste subjectively decreased to 70%, and after 6 weeks the symptoms disappeared. In addition to increased sensitivity of the mouth, gastro-oesophageal reflux might have created her obstinate sour-taste sensations. It is suggested that in such cases PPI therapy should be attempted.- - - - - - - - - - ranking = 0.01721154268765keywords = mouth (Clic here for more details about this article) |
5/7. An unusual presentation of chronic graft-versus-host disease in an unrelated bone marrow transplantation.The case described is that of an unrelated bone marrow transplantation in a 43-year-old man. Although the major histocompatibility complex met the criteria for a perfect genotypic match, de novo graft-versus-host disease developed with unusual manifestations involving structures of the oral cavity and associated areas. The loss of taste and smell, as well as profound xerostomia, was treated by stimulating salivary flow. Synergistic sialagogues were used with the hope that an increase in salivary production would mediate an improvement in taste and smell.- - - - - - - - - - ranking = 0.125keywords = oral cavity, cavity (Clic here for more details about this article) |
6/7. Oral Crohn's disease: report of two cases in brothers with metallic dysgeusia and a review of the literature.Between 4% and 14% of patients with intestinal Crohn's disease (CD) may manifest the typical oral changes of this disorder. These changes include labial and intraoral inflammatory tissue hyperplasia with fissuring ("cobblestoning") and swelling. In addition, angular cheilitis and regional lymphadenopathy may be present. We report two cases of oral CD in brothers, in whom the unusual symptoms of metallic dysguesia and gingival bleeding were prominent features. Despite the well-recognized familiar incidence of CD, a review of the literature shows that in no previous case reports has familial oral CD been noted. Successful symptomatic and objective treatment results were obtained with a mouthwash preparation of triamcinolone acetonide, tetracycline, and lidocaine.- - - - - - - - - - ranking = 0.0086057713438249keywords = mouth (Clic here for more details about this article) |
