    Notizen: Summary A histomorphometric analysis was performed on trephine biopsies of the bone marrow in 55 patients with chronic myeloproliferative disorders (CMPDs) and marked thrombocytosis (platelet count exceeding 600 × 109/l). This study aimed at discriminating primary (essential) thrombocythaemia (PTH) from the various other subtypes of CMPDs presenting with thrombocytosis. Following the diagnostic requirements postulated by the Polycythemia-vera-Study-Group for PTH and polycythaemia vera rubra (P.vera) and the generally accepted criteria for the establishment of chronic myeloid leukaemia (CML) and agnogenic myeloid metaplasia (AMM), our cohort of 55 patients was divided into the following subgroups: CML (16 cases), P.vera (11 cases), AMM (13 cases) and finally PTH (15 cases). Histomorphometric measurements revealed that PTH was distinguishable from the other subtypes of CMPDs with respect to several histological variables: patients with PTH had a normal amount of neutrophilic granulo- and erythrocytopoiesis as well as a non-increased content of reticulin (argyrophilic) fibers in contrast to the findings in CML, P.vera and of course AMM. Moreover, sizes of megakaryocytes and their nuclei were significantly greater in PTH and internalization of haematopoietic cells (emperipolesis) was more frequently encountered in comparison with the other subtypes of CMPDs. Deviation of the circular perimeter of megakaryocyte shape was most prominently expressed in CML and AMM, and consequently generated an increased number of a-nuclear cytoplasmic fragments. In contrast to this feature aberration of the nuclei from a circular outline occurred in a less pronounced way in CML, but was excessive in P.vera, AMM and PTH. Our morphometric evaluation demonstrates that certain histological features may serve as a valuable aid in discriminating PTH from the other occasionally thrombocythaemic subtypes of CMPDs.

    Beschreibung / Inhaltsverzeichnis: Abstract E. Grosshans and L. Marot first described blaschkitis in 1990 as a linear inflammatory dermatitis following lines of Blaschko in an adult patient. We report another case which occurred in a 38-year-old woman who developed an extensive, linear, erythematosquamous dermatitis involving the face, all limbs and the trunk. The patient's serum tested positive for antinuclear antibodies at a dilution of 1:640. The lesions regressed spontaneously within 4 weeks. Blaschkitis is a distinct entity which corresponds neither to a known inflammatory dermatitis in the lines of Blaschko nor to an hamartoma nor to an X-linked disease. Cutaneous antigenic mosaicism, the expression of which might be induced by a viral infection, could trigger this localized inflammatory T-cell response. This hypothesis relates blaschkitis to other cutaneous autoimmune diseases, as does the presence of antinuclear antibodies. We therefore suggest renaming this type of inflammatory dermatitis Grosshans-Marot disease in honour to the dermatologists who first described the entity.
    Notizen: Zusammenfassung Die “Blaschkitis”, eine blaschkolineäre Dermatitis im Erwachsenenalter, wurde von E. Grosshans und L. Marot 1990 erstmals als Entität beschrieben. Wir berichten von einem weiteren Fall einer “Blaschkitis” bei einer 38-jährigen Patientin ohne Vorerkrankungen, die an Kopf, Hals, Armen, Beinen und extremitätennahen Rumpfbereichen blaschkolineäre erythematosquamöse Läsionen entwickelte. Es fanden sich antinukleäre Antikörper mit einem Titer von 1:640. Spontane Abheilung trat innerhalb von 4 Wochen ein. Bei der “Blaschkitis” handelt es sich weder um eine blaschkolineäre Variante einer bekannten Dermatose noch um eine hamartomatöse Fehlbildung noch um einen X-chromosomal-dominanten Gendefekt. Ein Mosaik kutaner Antigene mit Expression im Laufe des Lebens (z. B. virusinduziert) könnte zu dieser blaschkolineären T-lymphozytären Entzündungsreaktion führen. Diese Theorie rückt die blaschkolineäre Dermatitis im Erwachsenenalter in die Nähe der Autoimmunerkrankungen, ebenso die gefundenen antinukleären Antikörper. Nachdem es sich bei der “Blaschkitis” um eine eigenständige Entität handelt und verschiedene Namengebungen sich international nicht durchsetzen konnten, möchten wir vorschlagen, sie nach den Erstbeschreibern Morbus Grosshans-Marot zu benennen.

    Notizen: Abstract The properties of ion channels in patches from the luminal membrane of cultured monolayers of type II alveolar epithelial cells from adult rat lung have been studied. In excised patches, prepared as described to yield the “outside-out” configuration (with cesium ions in the bathing solutions to suppress currents arising from potassium channels), we observed anion-selective channels with a conductance of 350–400 pS, and burst lengths lasting seconds. When patches were bathed in solutions with equal chloride concentrations, channels opened and closed spontaneously at membrane voltages close to zero, but tended to close when the potential was shifted by ±10 mV, particularly in the negative direction. Other anions could pass through these channels with a permeability sequence of I(1.5)〉Br(1.02)=〉Cl(1.00)〉NO3(0.9)〉gluconate(0.6) but there was a very low permeability for sodium (P Na/P Cl=0.015±0.006). Calcium ions reduced channel conductance. The channels probably have a role to play in salt absorption by this epithelium, but insufficient information is available about how sodium crosses it for the role of the anion channels in transport to be defined with confidence.

    Notizen: Abstract A simple, non-invasive, non-radioactive liverfunction test is proposed. After an oral dose of 3 mg 15N-methacetin per kilogram body mass, the kinetics of 15N excretion via urine were characterized by the quotient of the amounts of 15N excreted in two successive urine samples (Q value). The stable nitrogen isotope 15N was found to be an excellent and easily detectable indicator of the sum of all methacetin metabolites present in urine. Alterations in the nature or ratio of methacetin metabolites due to liver diseases could not be found. From the investigation of 11 men, 3 pregnant women and 15 children, a clear difference was observed in Q values of healthy persons and patients suffering from liver-cell-activity diseases. The discriminating power of our new liver-function test is shown to be equivalent to that of the 14CO2 breath test.
