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.

[Metal intolerance. A frequent condition, but difficult to diagnose].

Many of the methods and devices used for incompatibility testing of metals and alloys today are of questionable scientific value. Neither epicutaneous testing nor other diagnostic adjuncts from the realm of alternative medicine, nor patient-history data contained in so-called dental alloy passports, are generally able to yield any useful information. Analysis is particularly difficulty in situations where metallic components are cemented in place in the oral cavity. For many years now, the so-called splinter test has proven its value as a means of non-destructively identifying the type of alloy used. It can also be used for detecting persistent corrosion-prone adhesive oxides and soldering joints as causative agents of metal-related noxious processes. This article presents a number of case reports to demonstrate the reliability and the precision of the splinter test. Over a period of 10 years, more than 1600 splinter analyses have been performed at the University of Basle Center of Dentistry. According to a pertinent survey, these analyses were able to contribute to full treatment success in 63% of the cases, to partial success in 27% of the cases, and to no success in only 10% of the cases.

[Drug related taste disturbances: emphasis on the elderly].

BACKGROUND: Taste disturbances are common among the elderly due to physiologic changes, diseases, and medications. As many as 11% of elderly persons using multiple drugs report taste aberrations. The main danger of taste decline and disturbance in the old is food-anhedonia, causing loss of body weight via decreased calorie and nutrient intake. GOALS: To overview drug related taste disturbances emphasizing the elderly. METHODS: Review of Hebrew and English medical literature. RESULTS: Taste-disturbances can be divided into hypogeusia [diminished sense of taste], ageusia [absence of taste], and the 2 types of dysgeusia [taste distortion]: aliageusia [food related] and phantogeusia [taste illusions]. The mechanisms by which drugs impair taste are numerous, and may be related to drug chemical structure. The treatment of taste disturbances is empiric and has limited success. Treatments include: shifting drugs within the same class, zinc replacement (proven to enhance taste sensation for sweet, bitter and salty flavors), palliative measures (use of mints, sugarless chewing-gums, and bicarbonate mouthwashes), niacin and vitamin A ameliorate hypo and dysgeusia. CONCLUSIONS: Disturbed taste sensation is common among the elderly, and should be considered whenever unexplained nutritional decline is present. Scrupulous drug screening is mandatory, and other intervention modalities can be beneficial.

[Gustatory disturbances in multiple sclerosis].

90 patients with advanced multiple sclerosis were examined electrogustometrically and with taste solutions. In 4 cases only the bitter sensation was diminished all over the tongue. 4 other patients showed a prolonged latency. Besides a unilateral dissociated hypogenusia in 4 patients there were no further serious taste disturbances. One man showed a taste and sensory hyperpathia on one side of the body.

Electrogustometry in oral submucous fibrosis. A study in 50 cases.

Taste sensation were evaluated in 50 cases of Oral Submucous Fibrosis. Ankyloglossia was present in 28% and ulceration of tongue in 6% of cases. None of the cases had subjective impairment of taste sensation. Electrogustometry revealed impairment of taste in 46% of cases. Ankyloglossia was found to be related with the severity of Oral Submucous Fibrosis but impairment of taste was not related with the severity of the disease. The possible mechanism of the impairment of taste is discussed in brief.

[Odontostomatological changes induced by drugs. I].

The purpose of the present review is to describe the unwanted effects of drugs or chemicals in the orofacial region. The authors take into consideration the alterations of salivation such as xerostomia and ptyalism, disturbances of sense of taste, halitosis and pain and swelling of the salivary glands. The dental surgeon who suspects that an oral alteration might be a drug reaction can play an important role in preventing the development of more severe toxic effects. All this points to the importance of the knowledge of pharmacology for dental practitioners.

[Defect of taste in a patient with hypothyroidism].

A 74-year-old male presented with a total loss of taste of ten weeks' duration. He could not recognize both saturated sugar and salt solutions but his acuity for smell was normal. He also had a slight hoarseness, mild dysarthria and hyporeflexia of all extremities. Laboratory data revealed marked hypothyroidism and positive tests for antithyroglobulin and antimicrosomal antibodies. Shortly after the institution of thyroxine replacement, subjective response in taste acuity was seen. Almost complete recovery of taste followed after a month of incremental dose of thyroxine. The case indicates that thyroid hormones play a significant role in taste acuity. Hypothyroidism should be considered as one of the possible causes in taste defect.

[Loss of taste sensation in terbinafine administration].

Terbinafine is a new antifungal agent for oral treatment of dermatomycosis. Seven patients are reported who developed taste loss after treatment with terbinafine. In four of them, taste loss was complete while one patient was still able to taste sweet products, and a second and third patient no longer tasted salty and sweet products, respectively. In all patients, the onset of the adverse reaction occurred 4-8 weeks after starting treatment. As far as known, taste loss is a transient effect which disappears within 3-6 weeks after discontinuation of terbinafine.

[Burning mouth syndrome].

Burning mouth syndrome (BMS) is currently described as a burning pain in the tongue or other parts of mucous cavi oris without pathological signs of mucous cavi oris and changes in laboratory blood tests. On the basis of the current literature and our patients' examinations we described the incidence, etiology, symptoms and offered model of treatment of BMS.
