[Angioimmunoblastic lymphadenopathy with cutaneous manifestations in a 13-year-old girl].

We describe a 13-year-old girl with angioimmunoblastic lymphadenopathy. The patient's main symptom was a generalized pruritic maculopapular rash located mainly on the upper and lower limbs. In addition to the skin lesions, physical examination revealed enlarged cervical, axillary and inguinal lymph nodes. There were also hepatosplenomegaly and oedema of both hands. Blood examination showed elevated ESR, haemolytic anaemia, polyclonal hypergammaglobulinaemia and eosinophilia. Virus serology including HIV I and II and HTLV I was negative. Histopathological examination of a lesional skin biopsy showed superficial and deep dermal infiltrate extending into the subcutaneous tissue. The infiltrate consisted of lymphocytes, some with atypical nuclei, histiocytoid cells, and few eosinophils. There was also proliferation of dermal blood vessels. Examination of an enlarged cervical lymph node disclosed typical histopathological features of angioimmunoblastic lymphadenopathy and confirmed the diagnosis.

[Erythropoietic protoporphyria].

Erythropoietic protoporphyria (EEP) is the most frequently found erythropoietic porphyria in men. This inborn error of heme metabolism with autosomal dominant mode of inheritance is based on a deficiency of ferrochelatase. This defect leads to an increase for protoporphyrins predominantly in the red cells. Under the influence of sun light, especially UV-A, photohemolysis occurs and the content of protoporphyrin in the tissue increases. This is associated with acute sun burn like skin lesions, which usually clear up completely. Persistent skin lesions are seen in form of hyalinosis like infiltrations of the most intensively light exposed skin areas in some patients. Associated symptoms might be: gallstones or rarely a cirrhosis of the liver. Treatment with photoprotective ointments and especially carotinoids (beta-carotene, canthaxanthine) is very effective and only in some rare cases this symptomatic therapy fails. Prognosis of the disease is good. Only a few patients died of the associated hepatic failure.

[Modern internal therapy of skin diseases (author's transl)].

Modern internal therapy of skin diseases is based on a knowledge of pharmacology and biochemical pharmacology. The importance of the cytochrome P 450 system and its changes during treatment are referred to. Standard treatment in dermatology is not discussed but the literature is mentioned here. Treatment with glucocorticosteroids and non-steroidal anti-inflammatory substances are discussed in detail. The treatment of porphyria cutanea tarda with chloroquine shows good success. The results of carotinoid therapy of erythropoietic protoporphyria and non-porphyrin induced photodermatoses are debated.

Effect of hexachlorobenzene on enzymes of the steroid metabolism in rat liver.

Adult female Wistar rats were fed with a diet containing 0.05% hexachlorobenzene. On the 60th day of this treatment the specific activities of NADPH: delta 4-3-oxosteroid-5 alpha-reductase and the 3-hydroxysteroid dehydrogenases in rat liver microsomes were diminished compared to control rats. The cytoplasmatic 5 beta-reduction was higher in HCB treated rats than in control rats. These alterations of the steroid metabolism lead to increased formation of 5 beta-H-steroids which are known to be inducers of the porphyrin biosynthesis.

Induction of the hepatic microsomal and nuclear cytochrome P-450 system by hexachlorobenzene, pentachlorophenol and trichlorophenol.

The application of hexachlorobenzene (HCB), pentachlorophenol (PCP) and 2,4,5-trichlorophenol (TCP) to female rats led to an induction of both the microsomal and the nuclear cytochrome P-450 system in the liver. The increase of th mixed-function hydroxylase activities examined (7-ethoxycoumarin deethylase, 7-ethoxyresorufin deethylase, NADPH-dependent cytochrome c reductase, aminopyrine demethylase, benzpyrene hydroxylase) did not correlate strictly with the cytochrome P-450 content. Depending on the inducers and the substrates used, the content and the activity of the cytochrome P-450 were essentially smaller in the nuclei than in the microsomes. It was striking that in the nuclei those activities (benzpyrene hydroxylase, 7-ethoxyresorufin deethylase, 7-ethoxycoumarin deethylase) were preferably induced which can be attributed to the methyl-cholanthrene-induced form of the cytochrome P-450 (cytochrome P-448). These results suggest, also in the light of findings of other authors, the induction of different species of cytochrome P-450 in the nuclei and microsomes.

Laboratory investigations in patients with generalized psoriasis under oral retinoid treatment. A multicenter study of computerized data.

Numerous laboratory parameters were examined 235 patients with generalized psoriasis treated orally with retinoid and in 35 patients treated topically with anthralin as control. Computer evaluation of the obtained data revealed statistical trends to elevation of the total serum bilirubin level and increasing number of blood monocytes after long-term oral treatment. No other statistically significant changes of the laboratory data were found. Particularly, the liver function tests (transaminases, prothrombin and alkaline phosphatase) showed no significant alterations. Only in a few cases did the retinoid compound have an influence on the GPT and GOT levels. The reasons for this individual sensitivity to the drug remain unknown. No significant alterations were found in the control group treated topically with anthralin.

Two primary malignant melanomas in a patient with plasmacytoma.

The occurrence of two primary malignant melanomas (superficial spreading melanoma, superficial spreading melanoma with nodular growth) in a patient with diffuse plasmacytoma treated with chemotherapy and radiation is described. Such an association does not appear to have been reported previously.

[Occurrence of HBs-antigen and anti-HBs in patients with porphyria cutanea tarda (author's transl)].

Serum 63 patients with porphyria cutanea tarda (PCT) was examined for the presence of HBs-antigen and anti-HBs by the CombRIA-Au method. HBs-antigen was not detected in any of the examined blood samples. In contrast to these findings in 12 of the 63 PCT-patients (= 28 per cent), anti HBs was detected in the serum. The results showed that a high percentage of our PCT patients had been afflicted with an inapparent hepatitis B and were producing HBs-antibodies.
