BACKGROUND Pseudoallergic reactions (PARs) against both additives and natural foods have been reported to elicit chronic urticaria, but in natural food the responsible ingredients are largely unknown. OBJECTIVE The study was aimed at identifying novel pseudoallergens in food and focused on evaluating tomatoes, white wine, and herbs as frequently reported(More)
Facial palsy and orofacial swelling in childhood represent a challenge in differential diagnosis for paediatricians and dermatologists. One possible entity, Melkersson-Rosenthal syndrome (MRS), is a rarity in childhood. We describe a 9-year-old girl with the diagnosis of MRS who had episodic swelling of the upper lip and complete peripheral facial palsy,(More)
Severe generalized nodular and bullous mastocytosis of the xanthelasmoid type is described in a 7-month-old boy. Reddish to yellowish-brown xanthelasmoid papules and nodules first developed in the inguinal region a few weeks after birth and then progressively spread to cover nearly the entire body surface. There was severe pruritus and recurrent episodes of(More)
In order to clarify the pathogenetic role of basophils and mast cells in chronic urticaria, histamine and leukotriene (LT)C4 release was examined in washed mixed leukocytes (n = 8) and skin mast cells (n = 5) from patients with chronic urticaria and compared with the same cells from normal controls (n = 9). Anti-IgE-stimulated basophil histamine release was(More)
Releasability of mast cells and basophils to an IgE-dependent stimulus is regulated by extra- and intracellular factors which are only partly understood. As gangliosides are known to modulate receptor-dependent processes in various cell types, we have evaluated the effect of these molecules on mast cell mediator release. Human skin mast cells and the human(More)
The pathogenesis of Kaposi's sarcoma (KS) is often attributed to an infectious agent. In particular, the human herpesvirus 8 (HHV-8) was currently shown to be closely related to all known KS types, including HIV-associated KS, European classic KS, African endemic KS and iatrogenic KS. We report here on an HIV-negative, German patient of neither Jewish nor(More)
