    Notes: Objective The degree of reproducibility and precision of the mechanical direct profilometry and the intra- and interindividual fluctuations of 7 surface parameters were investigated.Material and methods Negative replicas were sampled from defined areas of the skin of 31 volunteers an evaluated with the profile-tracking device TKC 300 Hommeltester in order to derive data about the inter- and intraindividual fluctuations. To determine the precision of this method 6 roughness parameters and J of waviness of each replica were repetitively evaluated. The practicability was tested introducing minimal changes in the experimental set-up. Further, the effect of urea-containing creme on the skins topography was investigated in a double-blind clinical setting on a collective of 11 patients.Results The precision of this method is shown by nearly unchanged topographic parameters. Moreover, our data show smaller intra- than interindividual fluctuations of roughness (Ra) and waviness (Wt), being an important demand for clinical investigations.Conclusion In this paper we demonstrate that the parameters of both roughness as well as the recently introduced waviness can be conveniently evaluated with a high degree of precision with the direct profilometry.

    Notes: Protein contact dermatitis to meat is well known in butchers; spices are another source of potential contact allergy and usually are not recognized. We present a first case of contact-dermatitis to spice mix in a 39-year-old-butcher. The patient underwent skin prick testing (SPT) with standard allergens (ALK) and different meat and spice extracts (Stallergènes), scratch-patch testing with spice mix containing glutamate, paprika and other spices. Specific serum-IgE was measured with CAP-FEIA. SPT only showed an immediate-type sensitization to mugwort (+ +), as well as different spices (paprika +, curry +, cumin +) and camomile (+ + +). Scratch-patch tests were negative for different meat, but strongly positive for spice mix (+ + +) after 30 min (wheal and flare) and (+ +) after 48 h (infiltration and vesiculation). Two healthy controls were tested negative for spice mix used from that patient (scratch-patch). Specific IgE was slightly elevated for paprika 0.47 kU/L (CAP class 1), anise 0.43 kU/L, curry 0.36 kU/L and mugwort 3.83 kU/L. Sx1 atopy-multiscreen was 3.8 kU/L due to a sensitization to mugwort alone. The tests performed demonstrate an IgE-mediated contact allergy to spices but also a delayed type allergy to spice mix as a manifestation of the mugwort–spice syndrome in this individual. When testing for occupational dermatitis in butchers, protein contact allergy to spices must also be taken into consideration.

    Notes: Abstract: We report on a case of a 70-year-old woman with an ocular melanoma, which was diagnosed and treated 14 years ago. The patient was referred to the hospital with a suspected lymphoma. Cytological examination of bone marrow proved a marked infiltration with melanoma cells. Because detection of isolated tumor cells in the bone marrow of patients with various types of tumors was shown to be of prognostic significance and since current tumor-staging techniques are unable to detect single disseminated tumor cells or small aggregates of tumor cells, which might be the seed for subsequent metastatic relapse, we therefore evaluated the feasibility of immunocytochemical screening of bone marrow aspirates of 36 melanoma patients in different clinical stages using three monoclonal antibodies against melanoma-associated antigens in comparison with 43 non-melanoma control patients. Two of these antibodies (HMB45 and NKI-beteb) are directed against the melanoma antigen gp100/pmel17, whereas the third one (TA99) recognizes gp75/Tyrosinase-related protein 1 (TRP-1). None of the patients demonstrated a makroskopic bone marrow infiltration as was present in our patient with metastatic ocular melanoma. Seven (20.6%) of the 34 eligible melanoma patients presented with cells in the bone marrow positive for one or more of the above-mentioned melanosomal markers. Four of the positive patients were clinically free of tumors by the time of puncture, whereas the remaining 3 patients showed overt metastases in the subcutaneous fat (2 patients) and the brain (1 patient). On the other hand, 20 (66%) of the 29 patients with negative bone marrow findings also presented with clinical advanced disease with overt metastasis in the skin, lymph node, spleen, liver, lung, bone and brain. In conclusion, immunocytochemical screening of bone marrow samples is a feasible procedure that allows the detection of micrometastatic tumor cells in a subset of melanoma patients. Massive invasion of bone marrow with melanoma cells is a rare event even in far-advanced metastatic stages and no clear correlation between tumor load and bone marrow infiltration could be established.

    Notes: Background The expression of the proteinases cathepsins L and B are induced in tumors by malignant transformation, growth factors, and tumor promoters suggesting they play an important role in tumor invasion and metastasis. Methods By immunohistochemistry, procathepsin L and cathepsin B were studied in patients with Kaposi's sarcoma (KS). Formalin-fixed and paraffin-embedded tissues from 29 cases of KS (AIDS-associated KS, n= 24; non-AIDS-associated KS, n= 5) were immunolabeled with the polyclonal antibody directed against procathepsin L and the antisera directed against cathepsin B. Results Normal epidermis, eccrine sweat glands, and hair follicle expressed both cathepsins. We also found a positive staining for procathepsin L in normal blood vessels. In both “angiomatous” and “fibroblastic” lesions of KS no expression of these enzymes was observed. Conclusions These findings support the hypothesis of a benign autochthonous origin of the lesions, such as a hyperplasia.

    Notes: Zusammenfassung Es wird die Methode vonPope undStevens unseres Wissens erstmalig auf die Bestimmung von Aminosäuren im Blutserum angewandt. Die Ausführung des Untersuchungsganges mittels dieser Methode wird beschrieben. Durch diese Untersuchung wird nachgewiesen, daß eine starke Korrelation zwischen den Gesamteiweißwerten und dem freien Aminosäure-N-Spiegel im Serum besteht, die von den Voruntersuchern nicht genügend berücksichtigt worden ist. Dadurch können die Widersprüche, die sich bei Durchsicht der Literatur ergaben, weitgehend erklärt werden.

    Notes: Zusammenfassung Überblick des derzeitigen Standes der Forschung über den Hermaphroditismus verus mit einer erstmaligen zusammenfassenden Darstellung der bisher veröffentlichten 71 Fälle. Aus dieser ergibt sich, daß im Gegensatz zu der großen Zahl von Patienten mit Pseudohermaphroditismus bisher nur wenige mit Hermaphroditismus verus bekannt geworden sind. Eine eigene neue Beobachtung eines solchen wird mitgeteilt, unter besonderer Berücksichtigung auch der psychologischen Verhältnisse.

    Description / Table of Contents: Summary Patients with anti-SSA(Ro)-positive Sjögren's syndrome (SS)/lupus erythematosus (LE) overlap are a immunogenetically, serologically and clinically homogeneous group; what they have in common is an increased frequency of the HLA-DR3 phenotype, demonstrating SSA(Ro) antibody activity and the typical annular, polycyclic, erythematous lesions of subacute cutaneous LE. The sicca symptoms of SS may develop long after the cutaneous lesions of LE have been present, or vice versa, as well as vasculitic, purpuric, and Sweet's syndrome-like lesions. The elderly, predominantly female patients are at enhanced risk for pulmonary and neurological disease, but glomerulonephritis occurs infrequently. We present an 81-year-old, SSA(Ro) antibody-positive and HLA-DR3-positive woman with SS/LE overlap syndrome, who had cutaneous LE for 30 years, developing sicca symptoms, vasculitic and Sweet's syndrome-like skin lesions only years after the LE symptoms. Although there is still some discussion as to whether phenotypical SS/LE overlap represents a distinct disease or is secondary SS in SLE or systemic SS with cutaneous involvement, the SS/LE overlap syndrome seems well enough delineated to be considered as a disease entity with separate implications for therapy and prognosis. Its position in the spectrum of anti-SSA(Ro) antibody- and HLA-DR3-positive diseases and its relationship to SS and to anti-SSA(Ro) antibody-positive LE are discussed.
    Notes: Zusammenfassung Patienten mit phänotypischer Sjögren-Syndrom (SS)-Lupus erythematodes(LE)-Überlappung stellen eine immungenetisch, serologisch und klinisch einheitliche Krankheitsgruppe dar mit polyzyklisch-anulären, erythematosquamösen Hautläsionen, zirkulierenden SSA(Ro)-Antikörpern und hoher Prävalenz des immungenetischen Phänotyps HLA-DR3. Die Sicca-Symptomatologie des SS kann der LE-Symptomatik zeitlich folgen oder vorangehen. Neben Hautveränderungen wie beim subakuten kutanen LE (SCLE) kommt es zu vaskulitischen, purpuriformen und Sweet-Syndrom-artigen Hautläsionen. Die älteren, vornehmlich weiblichen Patienten zeigen ein erhöhtes Risiko pulmonaler und neurologischer Komplikationen. Demgegenüber kommt es selten zu einer Nierenbeteiligung. Eine 81jährige, anti-SSA(Ro)-, HLA-DR3-positive Frau mit 30jähriger Anamnese eines kutanen LE wird vorgestellt, bei der erst Jahre später neben den Hautveränderungen eines SCLE eine Sicca-Symptomatik, vaskulitische und Sweet-Syndrom-artige Hautveränderungen auftraten. Wenngleich diskutiert werden kann, ob es sich bei der phänotypischen SS-LE-Überlappung um ein eigenständiges Krankheitsbild oder um einen LE mit sekundärem SS bzw. ein primäres SS mit Hautmanifestationen handelt, scheint das SS-LE-Überlappungssyndrom hinreichend gut charakterisiert, um es als eine Krankheitsentität mit eigenen Implikationen für die Therapie und Prognose anzuerkennen. Die Stellung des SS/LE-Überlappungssyndroms im Spektrum der anti-SSA(Ro)-, HLA-DR3-positiven Erkrankungen, und die enge immunologische Verwandtschaft zum SS und zum anti-SSA(Ro)-positiven LE werden diskutiert.

    Description / Table of Contents: Summary The periungual fibromas in tuberous sclerosis are also known as Koenen tumors. Joannes Henricus Maria Koenen was born on March 10, 1893, in Eindhoven and died in Bois-le-Duc May 29, 1956. From 1910 to 1918 he studied medicine at the University of Amsterdam. Then he worked as a physician at the ’’Coudewater’’ asylum in Rosmalen and from 1929 in the ’’Voorburg’’ asylum in Vught. In 1932 he published his publication concerning a family with tuberous sclerosis in which photographs of periungual fibromas are shown. His thesis in 1933 at the University in Leiden was titled ’’Imbecility in children. Its Importance in pedagogic and social regard, by reason of an investigation in some communities in Noord-Brabant’’. Later he was appointed director of a state mental institution. The periungual fibromas in tuberous sclerosis were first described by Richad Kothe in Munich in 1903.
    Notes: Zusammenfassung Die periungualen Fibrome bei der tuberösen Sklerose werden auch als Koenen-Tumoren bezeichnet. Joannes Henricus Maria Koenen, geboren am 10. März 1893 in Eindhoven, gestorben in Bois-le-Duc am 29. Mai 1956, studierte von 1910 bis 1918 an der Universität Amsterdam. Anschließend war er als Arzt am Coudewater-Irrenhaus in Rosmalen tätig, ab 1929 in der Heilanstalt Voorburg in Vught. Während dieser Tätigkeit schrieb er seine Arbeit über die tuberöse Sklerose, in der die periungualen Fibrome erstmals photographisch dargestellt werden. Seine Promotion erfolgte am 22. Juni 1933 an der Universität Leiden mit einer Arbeit zum Thema „Schwachsinnigkeit bei Kindern. Ihre Bedeutung in pädagogischer und sozialer Hinsicht, auf Grund einer Untersuchung in einigen Gemeinden in Noord-Brabant”. Später wurde Koenen Inspektor der Staatlichen Irrenaufsicht. Die Erstbeschreibung der periungualen Fibrome erfolgte bereits 1903 durch Richard Kothe in München.
