The palatal shape of upper removable appliances. Influence on the tongue position in swallowing.

In a clinical-experimental study the influence of variations in the palatal shape of upper removable appliances upon tongue position during swallowing was investigated. During a clinical examination of 35 dental students displaying a physiological swallowing pattern, the tongue position during swallowing was recorded by palatography on an individually adapted upper plate. During swallowing with a roughened plate with an individual palatal shape and an imitated palatal papilla, the tongue position was significantly more posterior than with a highly polished, unstructured plate. The number of students displaying a visceral swallowing pattern was significantly smaller with a roughened plate with palatal folds and papilla then with a polished, smooth appliance. A roughened, individually shaped appliance with palatal folds and palatal papilla should therefore be used after myofunctional therapy and in cases where disturbance of tongue function by the appliance is not desirable.

The influence of interferon-gamma and interleukin-4 on IgE production in B lymphocytes of patients with atopic dermatitis. A possible criterion for selection of patients for interferon therapy.

The regulation of IgE production in B lymphocytes of patients with atopic dermatitis by interleukin-4 (IL-4) and interferon-gamma (IFN-gamma) was studied. IL-4 stimulated IgE production in vitro in B-cells of healthy donors and of children with atopic dermatitis, but had only a marginal effect on the high basal level of IgE production by lymphocytes from adult patients with atopic dermatitis. The addition of IFN-gamma prevented in all cases the stimulation of IgE synthesis induced by IL-4. The production of IgG and IgM was differently influenced. These results indicate that the in vitro production of IgE by mononuclear cells from adult patients is more resistant to the regulatory effects of IL-4 and IFN-gamma than is that in B cells of children with atopic dermatitis. We propose that a previous in vitro test of the responsiveness of IgE-producing B cells to IFN-gamma may be used to select patients with atopic dermatitis for treatment with IFN-gamma.

[Effect of propyphenazone on drug biotransformation in the liver. A comparison with phenylbutazone using the aminopyrine breath test].

By means of the aminopyrine breath analysis the influence of phenylbutazone, propyphenazone and of the combination preparation Wofapyrin "new" on the aminopyrine-N-demethylation, a hepatic microsomal performance of biotransformation in patients with diseases of the rheumatic circle of forms was examined. The enzyme-inducing effect of phenylbutazone known from literature could be confirmed. On the other hand despite a relatively highly dosed one-week treatment propyphenazone did not lead to changes of the demethylation capacity of the liver in the majority of the patients. In individual cases increases of the capacity are possible. In general, however, the doses of propyphenazone usual in the practice for the treatment of acute feverish infections no disturbing effects of induction or inhibition on the metabolic liver functions represented by the amino-N-demethylation are to be expected. The enzyme-inducing effect of Wofapyrin "new" is to be ascribed to the phenyl-butazone component.

[Determination of sulfapyridine levels in serum--a possibility for the control of dose related therapy with sulfasalazine].

For determination of the sulphapyridine level there were used 83 sera of 57 patients with Crohn's disease or ulcerative colitis which were treated with salazosulphapyridine. In 22,8 percent there was a sulphapyridine level higher than the therapeutic range of the whole sulphapyridine of 20-50 micrograms/ml. The serum levels are below this range frequently. Sulphonamide containing drugs yield too high values. Generally no sulphapyridine is shown in the serum because of the missing splitting of the salazosulphapyridine in patients with colectomie. Low serum values are found at low patient-compliance. In diarrhoea sulphapyridine levels in the serum are decreased. Determination of the sulphapyridine level is suitable: a) for recognition of too high serum levels and therefore for prevention of side effects b) to make sure that the therapeutic range is reached.

[Comparative studies on the bioavailability of various drug forms of phenylbutazone and clofezone (Perclusone)].

The bioavailability (BA) of phenylbutazone and clofezone preparations had been determined in patients suffering from rheumatic diseases. Clofezone is a compound preparation of phenylbutazone and clofexamide, with which the phenylbutazone portion amounts to 49%. In spite of an equivalent dosage (0.4 g phenylbutazone or 0.8 g clofezone, resp.) significant differences in the phenylbutazone-serum level profile had partly been stated after the application of different kinds of the preparation of both the drugs. The oral administrations (phenylbutazone dragées, Perclusone capsules) resulted in a prompt resorption; the plateau values of the phenylbutazone concentration in serum had already been completed after 2-3 h. The resorption from suppositories was decreased. The serum level maximum with phenylbutazone suppositories occurred after 6 h, with Perclusone suppositories after 24 h only. Compared to the phenylbutazone i.v. injection, the phenylbutazone dragées proved a complete substance uptake into the systemic circulation, whereas a relative BA of 65% has been determined for Perclusone capsules. The BA of the phenylbutazone suppositories amounted to 67%, those of the Perclusone suppositories to 41%.

[Experiences with the 14C-aminopyrine breath test in liver cirrhosis and under the effect of sodium diclofenac (Voltaren)].

The 14C-aminopyrine breath test is a simple procedure for the non-invasive determination of the microsomal function of the liver. After the oral administration of a tracer dose of 2 microCi (74 kBq) of 14C-aminopyrine the 14CO2 activity of the expired breath air is determined in hourly intervals. There is a close correlation between its decrease and the elimination of aminopyrine from the plasma. Both the elimination constant of 14CO2 (Kbreath) and the maximal specific 14CO2 activity are useful quantitative parameters of the test. They allow conclusions as to the hepatic demethylation capacity. Both parameters were significantly lower in 15 patients with liver cirrhosis than in 12 control patients. The non-steroidal anti-inflammatory drug diclofenacsodium (Voltaren) did not significantly influence the demethylation of 14C-aminopyrine in 5 patients with rheumatic diseases and in 2 healthy probands. Further experiences with the breath test are necessary, especially with respect to its suitability for prospective investigations.

[Estimations of the serum levels of sulfapyridine on patients treated with sulfasalazin (author's transl)].

Estimations of the serum level of sulfapyridine in 21 patients suffering from colitis ulcerosa or Crohn's disease, have been carried out. Nearly 50 per cent of all the serum levels were within the therapeutic range between 20 and 50 micrograms/ml. Some factors influencing the sulfasalazine metabolism are mentioned. The estimation of the serum levels of sulfapyridine is a suitable method for supervision of patients receiving treatment with sulfasalazine.

[Pulmonary side effects of gold treatment].

On the basis of more than 35 cases from literature a survey of clinical and paraclinical findings, diagnostic criteria, differential diagnosis, therapy and prognosis of the pulmonary reaction evoked by gold is given. The first symptoms mostly appear within the initial phase of the treatment, after several weeks to months. Unexpectedly increasing dyspnoea, weakness, cough and feeling of sickness in patients who are treated with gold salts are warning signals which refer to the possibility of a lung injury by gold. The differential-diagnostic demarcation from rheumatoid lung, a rare extraarticular manifestation of the rheumatoid arthritis, may render difficulties. The latter, however, usually refers to a slower progressing, is not or only incompletely able to involution and scarcely reacts to cortisonoids. The gold-conditioned pulmonary changes in most cases completely involve after a well-timed finish of the treatment with the gold-preparation. Cortisonoids are given for the acceleration of the remission. The prognosis is in general good. However, it depends on the fact, how long the gold treatment is still continued after the appearance of the pulmonary side-effect.
