[Clinical experiences of the medication to taste disturbance by serum trace deficiency, especially serum iron deficiency].

Serum zinc deficiency is known to be a major cause of taste disturbances, but the effects of serum iron deficiency on taste disturbances are not widely known. In the present study, we clinically investigated the relationship between taste disturbances and serum iron deficiency as well as the results of pharmacological therapy. The clinical and serological test results of 25 patients with serum iron deficiency (3 men and 22 women; mean age +/- SD, 56.1 +/- 16.5 years) were reviewed at the Department of Otolaryngology, Hospital of Hyogo College of Medicine. All of the patients had been seen at the hospital between January 1999 and February 2003. Electrogustometry (EGM) and the filter paper disc method (FPD) were used to measure taste function. The patients were treated with iron and zinc supplements. The age distribution of the patients peaked at the ages of 40 and 70 years. The ratio of males to females was 1:7. Based on the EGM results, 70% of the patients exhibited taste disturbances. The FPD results showed that the recognition threshold of sour tastes was slightly higher than that of the other tastes. No significant difference in the results of treatment was seen, regardless of the duration of the deficiency. These results suggest that treatment with iron and zinc medicine is useful for correcting taste disturbances caused by serum deficiencies of trace elements.

[Electric gustatory threshold in diabetics and its clinical significance].

Electrogustometry was performed in diabetics and the correlation between the electric gustatory threshold and clinical factors of the patients (age, disease period and diabetic complications) were evaluated (n = 50). The results obtained were as follows: 1. The electric gustatory threshold rose with aging. The patient age range for further analysis was confined to 50 approximately 69 years old (n = 34) to exclude age dependency. 2. The patients with longer disease histories tended to show a higher electric gustatory threshold, indicating that taste abnormalities in diabetics progress with disease duration. 3. Elevation of the electric gustatory threshold in diabetics was observed before onset or at the earliest stage of the three major complications (diabetic neuropathy, retinopathy and nephropatho), and the threshold rose further with the progression of diabetic complications. Thus, the electric gustatory threshold is a sensitive indicator of diabetic nephropathy and was demonstrated to be a remarkably useful indicator for the prevention of diabetic complications, since it allows detection of the three major diabetic complications at their earliest stages.

[Burning mouth syndrome].

Burning sensation of the tongue is a common complaint. In some patients this is diagnosed as Burning Mouth Syndrome (BMS). The prevalence of BMS is 0.8-19% of the general population. The typical complaint is localized to the anterior part of the tongue and may be accompanied by dry mouth sensation or taste disorder. The differential diagnosis of BMS is based on the specific details of the complaint, the clinical findings and laboratory results. The patients population consists of mainly post-menopausal women, even though it can appear in younger patients of both genders. The pathogenesis is only partially identified. There are different treatment approaches.

[Testing the sense of taste using validated procedures].

Psychophysical tests related to the sense of taste are usually less complex than those of the sense of smell. In addition to global tests a regional examination of the sense of taste might be indicated to search for nerve lesions. There are numerous validated psychophysical tests available based on the administration of liquid or solid substrates. The use of electrical currents (electrogustometry) is especially feasible for a rapid regional testing. The registration of gustatory event-related potentials to objectify results from psychophysical examination is possible although limited to a few centers world-wide.

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.

[An evaluation of the usefulness of impulse-current stimulation in electrogustometry--preliminary report].

UNLABELLED: Electrogustometry is a simple and fast method of quantitative taste examination. The direct-current monopolar stimulating equipment was most frequently used until now. Aim of the study was to evaluate usefulness of the new method based on bipolar stimulation with impulse-current Furthermore, the authors wanted to determine taste thresholds using the equipment. MATERIAL AND METHODS: 50 healthy volunteers (25 women and 25 men) in the age of 17-50 were involved. The volunteers had a careful otolaryngological examination. Then the taste thresholds for each quarter of tongue were determined using the new equipment. Additionally, ten of the group of volunteers was examined in accordance to repetition time values. RESULTS: the determined values showed symmetry of taste thresholds, among the range of 4.9-26 microA for anterior 2/3 of the tongue and 41.5-93 microA for the 1/3 posterior. The examination with consideration to repetition time did not show increase of taste threshold after ten minutes stimulation. CONCLUSIONS: in conclusion the new kind of electrogustometry is precision and repeatable taste diagnostic method. Moreover the way of stimulation does not cause the phenomena of fatigue and adaptation.

Taste alterations in liver cirrhosis: are they related to zinc deficiency?

Patients with chronic liver disease may have taste impairment and altered zinc metabolism. We evaluated Taste Detection Thresholds (TDTs) in 60 patients with liver cirrhosis and correlated the findings with disease severity and alcoholic etiology. Plasma zinc levels and urinary output were also measured. A placebo-controlled treatment trial with zinc sulphate was made in 15 patients with compensated cirrhosis in order to ascertain whether zinc deficiency caused taste alterations. Taste detection of salty, sweet and acid tastants was significantly impaired in all cirrhotic patients in comparison with normal subjects. TDTs were not influenced either by the etiology or the severity of the disease. All groups of patients had low plasma zinc levels and decompensated cirrhosis had a significantly increased urinary output of zinc. No correlation was found between taste acuity and plasma zinc levels when only cirrhotic patients were considered. The effect of zinc supplementation on TDTs did not appear to be inferior to that of the placebo. Our results indicate that taste impairment in cirrhotics is due to the disease process per se and not to zinc deficiency.

A case report of congenital aglossia.

A case of congenital aglossia was orthodontically treated and long-term retention was observed from the age of 15 to 27. The patient had congenital absence of three lower incisors, abnormally small mandible (micrognathia), severe overbite and a telescopic bite in the premolar region accompanied by an extremely narrow lower arch. Orthodontic treatment was begun when the patient was 15 years and 6 months old. The active treatment period was 2 years and 9 months. At the present time, nine years have passed since the end of the active treatment, and intercuspation between the upper and lower arches is still good. It is suggested that the maintenance of the lower arch width is essential for long-term retention in cases of congenital aglossia.
