[In memory of our Jewish colleagues who were murdered or committed suicide during the National Socialist Era].

With this article, we commemorate our Jewish colleagues who were murdered or committed suicide during the National Socialist Era in 1933-1945. Additionally, this article should provide an impulse to create a worthy memorial place. We thereby propose to put up commemorative plaques, e.g. in front of the administrative office of the German Dermatologic Society. Fifty-six Jewish dermatologists were killed in concentration camps in the National Socialist Era; 23 died in Theresienstadt, 19 in Auschwitz, and 14 in other concentration or extermination camps. Thirteen Jewish dermatologists committed suicide.

[Pancreatic panniculitis with neuroendocrine pancreatic carcinoma].

Pancreatic panniculitis is a rare complication occurring in 0.3-3% of patients with pancreatic disease. Clinical features include erythematous painful subcutaneous nodules usually on the lower leg and foot. A 72-year-old man was diagnosed in 2002 with a neuroendocrine carcinoma of the head of the pancreas. In 2003 following surgery and radiation therapy, he developed liver metastases and painful nodules on his legs. Lipase was found to be markedly elevated; amylase and alpha1-antitrypsin were in the normal range. Histopathologic examination of a nodule showed subcutaneous fat necrosis with ghost cells surrounded by an acute inflammatory infiltrate. The pathogenesis of pancreatic panniculitis is unclear. The pancreatic enzyme lipase may induce lipolysis and fat necrosis with secondary tissue inflammation.

[Lymphogranuloma venereum. Two cases from Dresden].

Lymphogranuloma venereum (LGV) caused by Chlamydia trachomatis serovar L1-3 was formerly a rare sexually transmitted disease in western countries. Recently, an outbreak of LGV and LGV proctitis among men who have sex with men (MSM) was reported from the Netherlands. We report two cases from Dresden, Germany, of white HIV1-infected MSM who presented in November 2004 with genital ulcers along with inguinal lymphadenitis (case 1) and ulcerative proctitis (case 2). The clinical picture and high titers of serum IgG and IgA antibodies pointed to infection with Chlamydia trachomatis. Appropriate specimens were positive for Chlamydia trachomatis with culture and PCR. Subsequent genotyping of the major outer membrane protein (MOMP) by restricted fragment length polymorphism confirmed serovar L2. Treatment with doxycycline for 3-4 weeks was effective. The incidence of LGV is increasing among MSM in Europe. Since most of the reported cases have been HIV1-infected and ulcerative STDs enhance HIV transmission, both health care providers and patients should be more aware of LGV.

[Extensive Fournier gangrene. A dermatologic emergency].

Fournier gangrene is a necrotizing fasciitis of the perineal and genital region, which almost exclusively affects men. The cause is a polymicrobial infection associated with superficial trauma, urological diseases and operations, as well as colorectal diseases. Diabetes mellitus, alcoholism, immunosuppression and other severe illnesses are frequent co-factors. Immediate administration of systemic broad-spectrum antibiotic therapy with coverage of both gram-positive and gram-negative bacteria combined with surgical debridement and intensive medical care can lower the high mortality rate of this condition.

[Combined topical therapy of psoriasis: position of calcitriol and vitamin D analogs].

Most patients with mild to moderate psoriasis require--often longterm--topical treatments: this frequently results in non-compliance especially when large body areas or the face are treated. Monotherapy with anthralin has been abandoned to a great extent while new formulations of topical corticosteroids, vitamin D and vitamin D derivatives have greatly extended the spectrum of topical antipsoriatic treatment modalities. In most instances, combinations of preparations with different pharmacologic modes of action are superior when compared with the respective monotherapy. This also holds true for combinations with a UVB or UVA light therapy. Preparations containing both a corticosteroid and vitamin D derivative are well suited for combining topical treatment with modern systemic antipsoriatic drugs.

[Late secondary syphilis with ulceration of the tongue during HIV coinfection: case report].

With the continuing rise of syphilis incidence, late stages and atypical courses with HIV-coinfection can be expected. A 45 year old HIV infected male presented with an unusual manifestation of late secondary syphilis on the tongue, which was first diagnosed as a squamous cell carcinoma but cleared after therapy with penicillin. He also exhibited psoriasiform and annular lesions on the trunk and hyperkeratotic papules on the palms of the hand and soles of the feet. A TPHA test was negative due to a prozone phenomenon. With this case, we would like to emphasize the formerly well known relationship between the lesions of tertiary syphilis on the tongue and development of secondary carcinoma.

Multicentre, phase II trial on the safety and efficacy of topical tacrolimus ointment for the treatment of lichen sclerosus.

BACKGROUND: Lichen sclerosus is a chronic inflammatory autoimmune disease causing significant sclerosis, atrophy and pruritus. Treatment remains unsatisfactory, with potent corticosteroids being the most effective therapy. OBJECTIVES: To conduct a multicentre, phase II trial to assess the safety and efficacy of tacrolimus ointment 0.1% for the treatment of lichen sclerosus with a follow-up period of 18 months at 10 university and teaching hospitals in Germany and Austria. METHODS: Eighty-four patients (49 women, 32 men and three girls) aged between 5 and 85 years with long-standing, active lichen sclerosus (79 with anogenital and five with extragenital localization) were treated with topical tacrolimus ointment 0.1% twice daily for 16 weeks. Computerized analysis of the lesional area was performed. The primary endpoint was clearance of active lichen sclerosus. Secondary endpoints were time to optimal response, reduction of sclerosis and duration of remission. RESULTS: The primary endpoint (clearance of active lichen sclerosus) was reached by 43% of patients at 24 weeks of treatment. Partial resolution was reached in 34% of patients. Maximal effects occurred between week 10 and 24 of therapy. Treatment led to a significant reduction of the total lesional area (P < 0.01) and to a significant decline in the total symptom score (P < 0.005). Symptoms (e.g. itching) and findings (erythema, erosions and induration) showed significant improvement. No serious adverse events were observed. There were three (9%) recurrences during the follow-up period. CONCLUSIONS: Topical tacrolimus ointment 0.1% was safe and effective for the treatment of long-standing active lichen sclerosus.

[Increase in syphilis and STD coinfections in HIV-infected individuals in Dresden].

BACKGROUND: In the past few years, increased diagnoses of syphilis and other sexually transmitted diseases (STD) have been reported in the cities of the United States and Europe, including Germany. The majority of cases identified were men who have sex with men (MSM). PATIENTS AND METHODS: A retrospective chart review of 144 HIV-infected patients from Dresden enrolled between 2000 and October 2003 was analyzed for the prevalence of syphilis and other STDs and compared with previous data of 104 patients collected between 1993 and 1999. RESULTS: The seroprevalence of syphilis increased from 13.5% to 17.5%, mainly due to a marked increase of active early syphilis from 0% to 7% of patients, all of whom were MSM. 63% of the patients had clinical or serological signs of other STDs. CONCLUSION: These data confirm previous reports on the increase of syphilis among MSM. The frequent occurrence of other STDs in HIV-infected patients outlines the need for special STD screening offers and adequate counseling.

[Pigmented lesions of the genital mucosa].

Pigmented lesions of the genital mucosa are more frequent in women than in men. They represent a spectrum of different benign entities. A biopsy is always recommended when the diagnosis cannot be made with certainty on clinical examination and dermatoscopy. Differential diagnostic considerations include melanocytic nevi, blue nevi and syndromes featuring lentigines. Malignant melanomas of the penis and vulva are uncommon tumors which usually appear in elderly patients. They frequently present as painless palpable nodules at routine examination. The treatment consists of excision with histological control of the margins. An aggressive surgical approach has not been shown to prolong the poor 5-year survival. Cooperation with gynecologists and urologists is essential for the optimal management of such patients.

Review of the potential photo-cocarcinogenicity of topical calcineurin inhibitors: position statement of the European Dermatology Forum.

Topical Calcineurin Inhibitors (TCIs) used for the treatment of atopic eczema modify the immune regulatory function of the skin and may have the potential to enhance immunosuppressive ultraviolet (UV) effects. Current recommendations on UV protection in eczema patients treated with PCIs are inconsistent and have given rise to uncertainty and anxiety in patients. Therefore, the European Dermatology Forum (EDF) developed a position statement which reviews critically the available data with regard to the problem, especially analysing and commenting the limitations of rodent models for the human situation. There is no conclusive evidence from rodent trials to indicate that long-term application of TCIs is photococarcinogenic. There is a need for further studies to investigate the validity of mouse models as well as long-term cohort studies in patients using TCIs. Available data suggest that long-term application of TCIs is safe, that there is no evidence of increased skin cancer risk and that it is ethical to treat patients with TCIs when indicated.

[Skin changes in diabetes mellitus].

Diabetes mellitus is the most frequent metabolic disorder. Just under 5 million people suffer from this disease in Germany. Four types of diabetes mellitus are distinguished: type 1 diabetes, type 2 diabetes, other specific diabetes forms, and gestational diabetes. Many characteristics of diabetes mellitus including skin changes are already manifest in the "prediabetic" stage when glucose tolerance is limited so that every elevation of blood sugar levels must be considered pathological. Changes in skin due to diabetes mellitus can be categorized into four disease groups: skin infections, skin diseases found overly frequently in association with diabetes mellitus, skin alterations due to diabetic complications, and reactions to antidiabetic treatment.

Risk and protective factors for sporadic basal cell carcinoma: results of a two-centre case-control study in southern Germany. Clinical actinic elastosis may be a protective factor.

BACKGROUND: There are very few data regarding sun exposure behaviour of patients with basal cell carcinoma (BCC) in central Europe. OBJECTIVES: A case-control study of patients with sporadic BCC was conducted to assess the risk of occupational and leisure-time sun exposure behaviour, precursor lesions for skin cancer and phenotypic factors on the development of sporadic BCC in Ulm and Dresden, Germany. METHODS: A comparison was made of 213 patients with BCC (128 from Ulm, 85 from Dresden; 103 men and 110 women; median age at diagnosis 69 years) and 411 controls (237 from Ulm, 174 from Dresden; 197 men and 214 women; median age 58 years). Crude odds ratios (ORs) and corresponding 95% confidence intervals for all of 64 possible risk factors revealed strong associations in 33 items. Selection of important risk factors was performed in a multiple logistic regression. RESULTS: For sporadic BCC, an increased risk was shown for persons with actinic cheilitis (OR 7.1), actinic keratosis (OR 2.7) and solar lentigo (OR 2.5). The only phenotypic factor indicating risk of sporadic BCC was hair colour, with a higher risk for red/fair than brown/black hair (OR 4.3). There was an increased risk for persons with BCC in first-degree relatives (OR 5.1) and those with sunburn 20 years before sporadic BCC was diagnosed (OR 3.6). Additionally, occupational ultraviolet (UV) exposure appeared to be a risk factor (OR 2.4). In contrast, clinical actinic elastosis showed a protective effect (OR 0.1). CONCLUSIONS: In contrast to earlier reports, clinical actinic elastosis turned out to be the only protective factor for sporadic BCC. A special relationship between wrinkling and BCC risk could not be shown. For basic research, future work should be aimed at elucidating further the different forms of collagen repair processes after intermittent and/or chronic UV exposure. The data strongly support the recommendation that a change in recreational UV exposure habits in individuals, and sunburn avoidance in particular, are necessary not only because of the increased long-term risk of melanoma, but also because of the risk of other skin cancers such as sporadic BCC.

[The treatment of atopic dermatitis in adults with topical calcineurin inhibitors].

In about 60% of cases, atopic eczema can persist in adulthood with distinctive clinical features and disease course. The introduction of the topical calcineurin inhibitors pimecrolimus 1% cream and tacrolimus 0.03 and 0.1% ointment clearly improves the long-term management of atopic eczema in adult patients; this has been shown in several large clinical studies and is confirmed by the growing practical experience with these substances. Topical calcineurin inhibitors are, even when applied for weeks and months, safe, well tolerated and efficient; they have a rapid and positive effect on pruritus and the potential--as shown in clinical studies with pimecrolimus 1% cream--to reduce the number of eczema flares, to significantly prolong the time to a first flare and to reduce or even eliminate the need for topical corticosteroids.

Demonstration of UVB-induced synthesis of 1 alpha,25-dihydroxyvitamin D3 (calcitriol) in human skin by microdialysis.

Cutaneous vitamin D(3) (VD(3)) is generated by UVB-induced photolysis of 7-dehydrocholesterol (7-DHC). VD(3) then undergoes sequential hydroxylation to calcidiol (25-OHD(3)) in the liver and to hormonally active calcitriol (1 alpha,25-(OH)(2)D(3)) in the kidney. Recently, we have described the epidermal VD(3) metabolic pathway by demonstrating the autochthonous formation of calcitriol in cultured keratinocytes. In this study we sought to determine whether photolysis of 7-DHC induced by irradiation of human skin with monochromatic UVB at 300 nm results in epidermal synthesis of calcitriol in vivo. Using a microdialysis technique we demonstrated that UVB irradiation results in a dose- and time-dependent increase in the calcitriol concentration in the extracellular fluid of UVB-irradiated skin. Topical treatment of skin with an ointment containing 2% ketoconazole immediately after irradiation suppressed UVB-induced intraepidermal calcitriol synthesis. This study demonstrates for the first time UVB-triggered synthesis of calcitriol in human skin in vivo. The link between UVB irradiation and synthesis of calcitriol in the skin may be of great importance for regulation of biological processes such as cell growth, differentiation, apoptosis and immunological reactions.
