We report a case of a 45 year old woman which fulfilled the criteria of chronic urticaria (remitting and relapsing bouts of erythematous and pruriginuos lesions without angioedema, lasted four months). Cutaneous manifestations were not related to a specific inducing factor, had no benefit from antihystamine and steroid drugs and were associated sometimes with mild gastroentric disorders. Patien...

Urticaria is among the most common skin diseases. It can be acute, chronic, mediated by a physical stimulus, or related to contact with an urticant. Some cases result from an underlying small vessel vasculitis. Our understanding of this condition is continuously expanding, and autoimmune mechanisms are now recognized as a cause of chronic urticaria. A search of the PubMed database (US National ...

BACKGROUND Sparse clinical observations suggest a possible association between food allergy to lipid transfer protein (LTP) and chronic urticaria (CU). OBJECTIVE To investigate the possible association between LTP hypersensitivity and CU. METHODS History of CU, and/or of NSAID hypersensitivity was prospectively assessed in 75 consecutive LTP-allergic subjects (M/F 27/48; age 33.6 years); th...

Introduction Strongyloides stercoralis (Bavay, 1876) is an important cosmopolitan helminth parasite. Human infection varies in regions throughout the world, being heavier in the tropics (Pessoa, 1972). The disease (Cochin China diarrhoea) varies also from mild intestinal discomfort to severe malabsorption syndromes and invasion of the peritoneal cavity and abdominal organs. Fatal cases have bee...

Sir, Chronic idiopathic urticaria may be autoimmune in origin (autoimmune urticaria), caused by functional autoantibodies that activate mast cells and basophils through cross linking the high affinity IgE receptor (FcεRIα) to secrete histamine. An incidence of 30% to 50% has been reported by various investigators. While there are no clinical features that distinguish ordinary urticaria from aut...

Introduction Chronic urticaria is a frequent disease that substantially affects quality of life of affected patients at a level comparable to that of patients suffering from heart diseases, on the waiting list for triple coronary artery bypass surgery (O’Donnell et al 1997). It is estimated that about 3% of the population of Western Europe suffer from chronic urticaria and the same disorder is ...

BACKGROUND Immunoglobulin (Ig) A deficiency is a primary immunodeficiency in which autoimmunity is frequently observed. Thirty to fifty percent of patients with spontaneous chronic urticaria have autoantibodies that are able to cross-link FcεRI on mast cells and basophils. METHODS We investigated whether spontaneous chronic urticaria in patients with IgA deficiency meets the criteria for auto...

Chronic urticaria (CU) is a skin condition characterized by the presence of intensively pruritic lesions occurring intermittently or continuously for more than 6 weeks. Because the cause(s) of CU are often not known, it is usually referred as chronic spontaneous urticaria (CSU) or chronic idiopathic urticaria (CIU). It affects 0.1%–0.3% of children. Moreover, solar urticaria (SU) is a rare chro...

Hydatid cyst is still endemic in various regions of the world. It is the most frequent cause of liver cysts worldwide. Urticaria is sometimes the first manifestation of the disease. However anaphylactic reaction and urticaria have been very rarely reported in the literature. Traditionally, surgery has been the only accepted mode of treatment; however, percutaneous treatment has recently been pr...

BACKGROUND Typical carcinoid syndrome is characterized by flushing, abdominal pain and diarrhea and occurs in <10 % of carcinoid tumor patients. Very rarely, initial signs include skin manifestations. Our purpose is to highlight cutaneous manifestations in the diagnosis and assessment of a patient with atypical manifestation of type I gastric carcinoid tumor. CASE PRESENTATION A 50-year-old w...
