[Potentials of the interdisciplinary care of children with ectodermal dysplasia].

Children with ectodermal dysplasia represent a group of patients demanding highly sophisticated dental care. Characteristic morphological and functional oral problems lead to special technical difficulties and additionally, the altered psychology of these children requires empathy in treatment. With respect to these problems, children with ectodermal dysplasia are treated in our clinics, multidepartmental cooperation. The interplay between stimulative, restorative and prosthodontic therapy has been shown to be of great benefit for these children.

High density avalanche chamber (HIDAC) positron camera.

A prototype positron camera has been constructed consisting of two high density avalanche chamber (HIDAC) detectors operated in coincidence with a resolving time (2 tau) of 40 nsec. The detectors are multiwire chambers, with specially constructed lead converters added to improve the photon detection efficiency at 511 keV. The current HIDAC detectors have a singles efficiency of approximately 12%, a sensitive area of 31 X 31 cm and an intrinsic spatial resolution of less than 2 mm full width at half maximum (FWHM). During data acquisition, the detectors are rotated around the patient in order to collect a complete angular data set. A three-dimensional image of the positron distribution is reconstructed from a single scan by weighted backprojection of the data into a matrix of either 64 X 64 X 64 or 128 X 128 X 16 voxels. The camera point response function is deconvolved by frequency-space filtering. Corrections are made during backprojection both for photon attenuation and for spatial variations in point source sensitivity. The reconstructed image is further corrected for contributions from accidental and scattered coincidences and displayed as a sequence of two-dimensional transverse, sagittal, or coronal sections. In addition, three-dimensional display is available using shaded graphics techniques. The prototype camera is currently undergoing clinical evaluation.

[Diagnostic value of mucin-histochemical reaction in biopsy specimens of the large bowel].

The present study was carried out to determine the value of mucin-histochemical reactions in normal and pathologically altered colorectal mucosa. Normal large bowel mucosa shows a regionally different pattern of mucin composition of the goblet cell. In adenomas, remarkable variations of mucin pattern can be observed. Well-differentiated adenocarcinomas contain only sparse amounts of sialomucin or neutral mucins but no sulfomucins. In inflamed large bowel mucosa, the content of sulfomucins decreases in dependence on the degree of inflammation. The changes of mucin composition in the goblet cells are of unspecific reactive nature because they can be observed in the same manner in neoplastic and inflamed mucosa. With the employed mucin-histochemical methods no essential informations can be obtained in addition to pathohistological diagnosis.

[Taboos and fears in the relationship of the therapist with his own family].

The following article confirms the necessity of family self-encounter of family therapist with a conflict-oriented approach and describes the problems of therapists dealing with their own present family and their family of origin. The empirical basis of this article are the experiences made during a three-years training course for analytic family therapists in Göttingen. Self-encounter with the own present family and family of origin was a substantial part of the course. Encountering families during treatment the therapist is endangered to aspire a rearrangement according to his unfulfilled wishful imaginations of his own family. This may paralyse the therapeutic process considerably. Coming to terms with one's own present family and family of origin is prevented by the unspoken agreement to conceal feelings and experiences in important situations. Especially the suffering of the single family member is taboo. In the family of origin an important reason for this seems to be the fact that children--no matter what age they are--always fear their parents. In the present family an important reason is the pre-conscious fear of having become guilty in respect to the children. Often there are struggles with partners and children to make them act in a different way as parents and brothers and sisters did. One's sore spots have remained the same in the present family and the family of origin. They seem to be exceptionally resistant to change. Repeated struggles about questions of style between partners are often an expression of unresolved ties to the family of origin, which do not permit partnership. A main result of the direct confrontation with the own family of origin was the insight that all participants had overestimated the degree of their individuation. Beyond the possibilities of training analysis, in which dyadic interactions are reproduced in the experience of the trainee, ego-syntonic behaviour and character armours became obvious, which were not perceptible in the transference relation. As an additional important access to the emotional network of one's own family the genogram--the genealogical tree constructed from a family dynamic point of view--is described.

Quantitation of the information content of multi-dimensional gas chromatography and low-resolution mass spectrometry in the identification of doping drugs.

On the basis of information theory, a comparison of the performance of the identification of compounds by multi-dimensional gas chromatography and binary-encoded low-resolution mass spectrometry is made for doping drugs. This group of compounds was not selected at random but according to their pharmocological effects. For these compounds it was observed that the m/e values of the peaks in the mass spectra are highly correlated, while a number of chromatographic columns can be found on which the retention data are only slightly correlated. As a result, the information content of two-dimensional gas chromatographic retention data on such columns equals the information content of binary-encoded low-resolution mass spectra. It is shown that the accuracy and precision of retention data in gas--liquid chromatography, and therefore the information content, can be significantly improved if the data are corrected for adsorption effects of the solid support and extrapolated to a limiting value in the case of asymmetric peaks.

Studies on the quantification of local tissue injury following intramuscular injection of aqueous solutions. VIII. The local lesion after application of turimycin in different preparations.

The increase in drug concentration in aqueous solutions is not responded to by a comparable enlargement of volume of necrosis after intramuscular injection. After application of TURIMYCIN the lesion is more voluminous than those caused by penicillin, lower than those following OTESOLUT and nearly equal to those caused by 5% WOFAPYRIN (phenylbutazone + aminophenazone 1:1).
