    Notes: Abstract Two-hundred and fifty-two computerized tomography (CT) scans of 107 patients with head injuries were analyzed. The most frequent consequence of trauma was a diffuse swelling of the brain in 91% of the cases. The severity of brain swelling and its course can be estimated by the compression of (or absence of) the intracranial cerebrospinal fluid space. These observations may be of prognostic value as well. By measurement of theHounsfield units (HU) in 52 cases the blood or water content in the brain tissues was assessed. An increase in blood content of the tissues (hyperaemia) can account for an increase in Hounsfield values. A decrease in HU suggests brain edema. The density measurements showed that in the first hours and days following head injury, the diffuse brain swelling was caused by severe cerebrovascular congestion in the majority (53%) of the cases. Immediate brain edema without a preceeding hyperaemic phase occurs less frequently (32%). Between the 1st and 4th day after injury, edema started to prevail, and between the 5th and 8th day the edematous type of brain swelling was present almost exclusively.

    Notes: Abstract In 96 patients with congenital absence of the uterus and upper vagina, the Mayer-Rokitansky-KüsterHauser (MRKH) syndrome, it proved possible to distinguish between the typical and the atypical form using laparoscopy. The typical form was characterized by symmetrical nonfunctioning muscular buds (the Müllerian duct remnants) and normal fallopian tubes, and the atypical form by aplasia of one or both buds, one bud smaller than the contralateral one, with or without dysplasia of one or both fallopian tubes. The atypical form was found in 52 patients (54.2%). Radiographs of the spine showed that congenital spinal abnormalities, especially the Klippel-Feil (KF) syndrome, were seen in 14 of the 52 patients with the atypical form only. Renal agenesis or ectopia together with the MRKH and KF syndromes, known as the MURCS association (MU: Müllerian duct aplasia; R: renal agenesis/ectopia; CS: cervical somite dysplasia), was diagnosed in 10/52 patients in the atypical group. From our results we conclude that additional cervical spine films in patients with the MRKH syndrome are indicated only in the atypical form the syndrome. In those cases where the MRKH syndrome is associated with the KF syndrome, the MURCS association should be considered.

    Description / Table of Contents: Zusammenfassung Untersuchungen der psoriatischen Hautveränderungen mittels der direkten und indirekten Immunofluorescenzmethode zeigen in der Hornschicht Immunoglobulin- und Komplementablagerungen auf. Das IF-Muster ist dasselbe wie bei der Bindung der im normalen Serum auftretenden anti-Stratum corneum-Antikörper an dem spezifischen Substrat, d.h. normaler Hornschicht. Die Bildung von Immunkomplexen zusammengesetzt von anti-Stratum corneum-Antikörpern scheint das Phänomen der «Squirting papilla» zu verursachen, wobei das normalerweise nicht zugängliche Stratum corneum unter der Einwirkung von Traumen oder Leukocyten-Proteinasen antigenisch wird. Die Proteinase-Produktion durch angeregte polymorphonukleare Leukocyten ist vermutlich ein wichtiger pathogenetischer Faktor in Psoriasis, wobei das Stratum corneum das Target ihrer Einwirkung ist und reaktiv (antigenisch) wird, was die in vivo-Fixation der Stratum corneum-Antikörper ermöglicht.
    Notes: Summary Immunofluorescence (IF) studies by the direct and indirect methods demonstrate immunoglobulins and complement bound in vivo in psoriatic scales. The IF pattern is comparable to that of stratum corneum antibodies (SCAb) bound in vitro on specific substrate, as visualized by the indirect IF method. Formation of immune complexes can be responsible for the “squirting papilla” phenomenon, and conversion of the stratum corneum — which is normally an inaccessible antigen — into its reactive form seems to be brought about by proteases of polymorphonuclear leukocytes. Stimulation of protease production by polymorphonuclears appears to be an important factor in the pathogenesis of psoriasis. The stratum corneum of the epidermis is probably the target, and becomes an antigen for SCAb present in the circulation.

    Notes: Abstract Samples of fresh thyroid tissue obtained from 15 patients undergoing thyroid surgery were incubated with iodine 125 in culture solution to which thyroid-stimulating hormone (TSH) had been added and then examined by autoradiography. The radioactivity registered actively during the 90-min incubation period was primarily found in the lumina of follicles. Even morphologically similar follicles showed very heterogeneous uptake of radioiodine; small follicles often contained the highest concentrations of activity. The method applied appears to be particularly useful for answering the question as to whether and to what extent individual papillary or follicular thyroid carcinomas are able to store radioiodine. This information obtained immediately after surgery may contribute towards establishing the patient's prognosis and help in deciding on postoperative therapy and follow-up. Because of the heterogeneity of radioiodine uptake, it is mandatory to examine a representative sample of carcinoma tissue in order to obtain well-established results.
