    Notes: Abstract. We describe a 56-year-old Caucasian man with history of multiple regressed basal cell carcinomas. During the last 20 years approximately 200 histologically proven basal cell carcinomas preferentially localized on the face were surgically treated. Several large skin grafts were necessary to cover the extensive tissue defects on the face and scalp. Although all excised tissues were histologically proven to be basal cell carcinomas with tumor-free margins, new tumors developed in proximity to the skin graft margins. The dissemination of the new tumors made it difficult to perform additional invasive operation procedures without influencing the cosmetic result. Thus, we used photodynamic diagnosis to improve detection and demarcation of the neoplastic tissues. This procedure facilitated surgical planning and enabled primary in toto excisions. Surgical trauma and a number of interventions were thus minimized with the consequence of improved cosmetic and functional results.

    Notes: Summary The safety of drugs in hepatic porphyrias has largely been established by clinical experience, which is very limited in the case of antineoplastic agents. We administered three cycles of polychemotherapy consisting of daunorubicin, cytarabine and 6-thioguanine, and modified supportive care to a 33-year-old Turkish woman suffering from acute myelogenous leukemia. The urinary excretion of total porphyrins, porphobilinogen, and aminolevulinic acid was continuously monitored. Excreation of these metabolites was permanently elevated, but the values were comparatively low during cytotoxic therapy while peak values were recorded at the onset of fever during bone marrow aplasia; yet there were no clinical signs of porphyritic attacks at that time. A few potentially unsafe drugs were tolerated without an increase in porphyrin excretion. Although the susceptibility to drugs is highly variable in patients with hepatic porphyrias, the treatment of malignancy in these patients seems justified as long as porphyrin excretion under therapy is not grossly elevated over baseline values and appropriately modified supportive care is administered.

    Description / Table of Contents: Zusammenfassung Es wird über einen 64jährigen Mann mit dem klinischen und biochemischen Vollbild der Porphyria cutanea tarda (P.c.t.) berichtet. Nach einer irrtümlich zu hoch gewählten Resochin®-Behandlung (1,250mg anstelle von 125 mg) kam es zu einer akuten Krise mit dreifacher Steigerung der Porphyrin-Ausscheidung, Fieber, Tachycardie, Hypertonie und Gelenkbeschwerden. Trotz einer Steigerung der Gesamt-Porphyrin-Ausscheidung im Urin auf ca. 20,000 mcg/l kam es nicht zu einer Änderung der Porphyrin-Vorstufen-Ausscheidung (ALA und PBG). Ebenso blieb das prozentuale Verteilungsmuster der Porphyrine (URO-, HEPTA-, HEXA-, PENTA- und KOPRO-Porphyrin) im Urin während dieser Ausscheidungs-Steigerung gleich. Die Behandlungsdauer ließ sich durch diese irrtümlich zu hohe Resochin®-Dosierung offenbar nicht verkürzen. Der Wirkungsmechanismus des Chloroquin bei der P.c.t. wird in einer Änderung der Membran-Permeabilität der Leber-Mitochondrien gesehen, wodurch es über eine kontinuierliche Porphyrin-Mehrausscheidung bis zur Erschöpfung der Porphyrin-Speicher kommen soll.
    Notes: Summary About a 65-year old patient with the typical clinical and biochemical characteristics of porphyria cutanea tarda (Pct) is reported. After treatment with Resochin® in an erroneously high dosage (1.250 mg instead of 125 mg) an acute crisis set in with a triple increase of porphyrin excretion, fever, tachycardia, hypertension and joint-discomfort. Despite the rise in excretion of total porphyrines in urine to approximately 18.000 mcg/l there was no change in the amount of the porphyrin precursors (ALA, PBG). The pattern of the porphyrin-metabolites (URO-, HEPTA-, HEXA-, PENTA-, COPRO-porphyrin)—expressed in rel.%—does not change during the excessive rise of porphyrin excretion. The duration Resochin®-therapy could obviously not be shortened by an initial too high dosage of chloroquine. The mechanism of action of chloroquine in Pct ist not clear. It is discussed that a change in the permeability of the liver mitochondria leads to a continously increased excretion of porphyrin and to an exhaustion of the hepatic porphyrin pool.

    Description / Table of Contents: Zusammenfassung An 100 gesunden Personen wurde überprüft, ob zwischen in vitro-Stimulierbarkeit der Lymphocyten (3H-Thymidin-Einbau im Lymphocytentransformationstest) mit Phytohämagglutinin, Pokeweed Mitogen und Concanavalin A und der in vivo-Reagibilität auf intracutane Phytohämagglutininapplikation (gemessen am mittleren Infiltratdurchmesser) eine Korrelation besteht. Zusätzlich wurde untersucht, ob diese beiden Parameter in bezug zur Reaktion auf die spezifischen Antigene Trichophytin, Candidin und Streptokinase-Streptodornase (positiv oder negativ reagierend) stehen. 1. Zwischen in vitro-Stimulierbarkeit der Lymphocyten mit Phytohämagglutinin, Pokeweed Mitogen und Concanavalin A und mittlerem Infiltratdurchmesser nach intracutaner Gabe von 2 µg Phytohämagglutinin besteht bei Normalpersonen eine gute qualitative Korrelation. Bei Verwendung niedrigerer Phytohämagglutinindosen fehlt diese Korrelation. Eine quantitative Korrelation des Infiltratdurchmessers mit der Phytohämagglutinin- und Pokeweed Mitogen-Stimulierbarkeit läßt sich nicht nachweisen. Für Concanavalin A findet sich eine negative Korrelation auf dem 99%-Signifikanzniveau. 2. Die in vivo-Reagibilität auf Phytohämagglutinin unterscheidet sich bei Personen mit negativen und positiven Reaktionen auf die spezifischen Antigene nicht. 3. Die Stimulierbarkeit mit Phytohämagglutinin, Pokeweed Mitogen und Concanavalin A der Lymphocyten von Personen mit positiven Reaktionen auf Trichophytin, Candidin und Streptokinase-Streptodornase liegt signifikant über der von Probanden mit negativen Reaktionen. 4. Die Ergebnisse sprechen dafür, daß die in vivo-Phytohämagglutinin-Testung eine gute Screening-Methode zur Beurteilung der cellulären Immun-Reaktivität darstellt. Die Anwendbarkeit dieser Methode zur Differenzierung von Immundefekten (vom T-Zell-Typ) erfordert noch weitere Untersuchungen.
    Notes: Summary 100 healthy persons were investigated to find out whether there is a correlation between a lymphocyte stimulation (3H-thymidine incorporation in the lymphocyte transformation test) with phytohaemagglutinin, pokeweed mitogen and concanavalin A and the in vivo reactivity to intracutaneous phytohaemagglutinin application (measured as medium diameter of infiltrates). Further we searched for an influence of positive or negative reactivity to the specific antigens trichophytin, candidin and streptokinase-streptodornase. 1. There is a good qualitative correlation in normal persons between in vitro lymphocyte stimulation by phytohaemagglutinin, pokeweed mitogen and concanavalin A and the medium diameter of infiltrates after intracutaneous application of 2 µg phytohaemagglutinin. Using lower doses of phytohaemagglutinin no such correlation could be found. A quantitative correlation between the medium diameter of infiltrates and lymphocyte transformation by phytohaemagglutinin and pokeweed mitogen cannot be demonstrated. For concanavalin A there is a negative correlation significant at the 99% level. 2. In vivo reactivity to phytohaemagglutinin does not differ in persons with negative and positive reactions to the specific antigens. 3. Lymphocyte stimulation by phytohaemagglutinin, pokeweed mitogen and concanavalin A of persons with positive reactions to trichophytin, candidin and streptokinase-streptodornase is significantly greater than in those with negative reactivity. 4. The results indicate in vivo phytohaemagglutinin testing as a good screening method to judge cell-mediated immunocompetence. The general applicability for differentiation of immunodeficient and immunocompetent patients is to be further investigated.
