[In case of pelvic pain desquamative inflammatory vaginitis is an important differential diagnosis]

Desquamative inflammatory vaginitis (DIV) is an uncommon, severe form of chronic vaginitis of unknown aetiology. The syndrome is characterised by profuse vaginal discharge, vulvovaginal irritation, dyspareunia and vaginal erythema. As the symptoms and signs are nonspecific, other causes of purulent discharge have to be excluded first. Definition necessitates specific wet smear findings. The purpose of this case report is to consider DIV as a diagnosis in women presenting with persistent vaginitis. An effective treatment using clindamycin and/or glucocorticoids is available.

Low prevalence of oral and nasal human papillomavirus in employees performing CO2-laser evaporation of genital warts or loop electrode excision procedure of cervical dysplasia

Risk of human papillomavirus (HPV) transmission during laser vaporisation of genital warts or loop electrode excision procedure is controversial. An oral rinse, a nasal swabs, history of HPV related diseases and data on HPV exposure were collected from 287 employees at departments of dermato-venerology and gynaecology in Denmark. A mucosal HPV type was found among 5.8% of employees with experience of laser treatment of genital warts as compared to 1.7% of those with no experience (p = 0.12). HPV prevalence was not higher in employees participating in electrosurgical treatment or cryotherapy of genital warts, or loop electrode excision procedure compared with those who did not. HPV 6 or 11 were not detected in any samples. Hand warts after the age of 24 years was more common among dermatology than among non-dermatology personnel (18% vs. 8.0%, p = 0.03). Mucosal HPV types are infrequent in the oral and nasal cavity of health care personnel, however, employees at departments of dermato-venereology are at risk of acquiring hand warts.

Alemtuzumab is effective against severe chronic lymphocytic leukaemia-associated paraneoplastic pemphigus

Alemtuzumab (ALZ) is a monoclonal antibody used in the treatment of a variety of lymphoproliferative diseases, primarily chronic lymphocytic leukaemia (CLL). Paraneoplastic pemphigus (PNP) is a severe mucocutaneous disease, which can occur in association with B-cell malignancies. A correct diagnosis of PNP relies on distinct clinical and histopathological features, and the demonstration, by direct immunofluorescence, of intercellular and basement membrane IgG deposits in the affected tissue. PNP is often refractory to immunosuppressive drugs and frequently has a fatal outcome. We report three cases where sustained remissions of both PNP and CLL were induced by ALZ. In one of these cases, ALZ was able to reinduce a sustained remission of PNP at the reappearance of the disorder years after the primary treatment. In all cases, the PNP diagnosis was confirmed by immunofluorescence. In conclusion, ALZ should be considered as a treatment option in severe CLL-associated PNP. Patients should be carefully selected and receive appropriate infectious prophylaxis before, during and after ALZ treatment, due to the risk of opportunistic infections secondary to combined disease- and drug-induced immunosuppression.

Glucocorticoid-induced Tumour Necrosis Factor Receptor (GITR) and its Ligand (GITRL) in Atopic Dermatitis

The glucocorticoid-induced tumour necrosis factor receptor-related gene (GITR) is expressed on regulatory T-cells (Treg), which are CD4+CD25+ lymphocytes. Binding of the GITR-ligand (GITRL) leads to downregulation of the regulatory function of Tregs. Patients suffering from a defect in their Tregs exhibit a condition in their skin resembling atopic dermatitis. GITR also exists in a soluble form, and increased levels of this lead to decreased levels of GITRL and thereby increased Treg activity. We have measured the levels of GITR and GITRL in plasma from atopic dermatitis patients and found it not to be increased. Furthermore, plasma levels of GITR and GITRL did not correlate with SCORAD. Both GITR and GITRL correlated with the levels of thymus- and activation-regulated chemokine/CCL17 and cutaneous T-cell-attracting chemokine/CCL27, two chemokines believed to play a major role in the pathogenesis of atopic dermatitis and the migration of Tregs and skin-homing T-cells. Immunohistochemistry showed GITR and GITRL were present in few dermal cells of both patients with atopic dermatitis, and normal healthy volunteers, and often localized in close proximity to each other. Since regulatory T-cells are localized in the vicinity of GITRL-expressing cells in atopic dermatitis skin, the GITR/GITRL interaction may serve to perpetuate the inflammation locally.
