Challenging cause of bullous eruption of the hands in the Arctic.

Phytophotodermatitis is caused by deposition of photosensitising compounds on the skin followed by ultraviolet exposure. We present an unusual case of a 29-year-old Australian male visiting Greenland who presented with severe itchy bullous eruption on his hands. The cause was a combination of exposure to lime fruit juice and prolonged sun exposure from the Arctic midnight sun.

[Haemorrhagic proctocolitis as primary manifestation of lymphogranuloma venereum in an HIV-positive male].

This is a case report of lymphogranuloma venereum (LGV) manifesting as haemorrhagic proctocolitis in a homosexual HIV-positive male. The primary symptom was a rectal abscess, which was initially surgically treated and subsequently insufficiently treated with single-dose tablet azithromycin. The patient's symptoms were successfully treated after a 21-day doxycycline regime.

[Chlamydia in Denmark].

Oculo-genital chlamydia caused by Chlamydia trachomatis is the most frequent sexually transmitted infection. The number of laboratory verified cases increases steadily in Denmark. This is due to an increased testing activity but also increased positivity rates.

Successful treatment of recalcitrant folliculitis barbae and pseudofolliculitis barbae with photodynamic therapy.

Unlabelled: Folliculitis and pseudofolliculitis barbae typically affects men with curly hair who shave too close. Treatment modalities vary in effectiveness and include improved hair removal methods, topical corticosteroids, topical and oral antibiotics, and retinoids as well as laser surgery. We report a novel treatment of recalcitrant pseudofolliculitis barbae and confirm effectiveness in recalcitrant folliculitis in a 58-year old man who responded completely following photodynamic therapy with methyl aminolevulinate.

Interleukin-21 restrains tumor growth and induces a substantial increase in the number of circulating tumor-specific T cells in a murine model of malignant melanoma.

New strategies of immunotherapy are currently being evaluated, and the combination of chemo- and immunotherapy has shown promising results. The cytokine interleukin-21 (IL-21) is known to enhance immune function, and in this study we have investigated its ability to boost the efficacy of chemoimmunotherapy-cyclophosphamide and adoptive cell transfer (ACT)-in the B16-OVA/OT-I murine model of malignant melanoma. Subcutaneous B16-OVA tumors were established in C57BL/6J mice 8 days before adoptive transfer of tumor-specific OT-I T cells.
