Un'esperienza tra cielo e terra, il nuovo complesso liturgico a San Felice sul Panaro dopo il terremoto

Il lavoro di tesi si prefigge di ricollocare un nuovo polo liturgico per San Felice sul Panaro, dopo la devastazione del terremoto. Il quasi completo crollo della principale chiesa parrocchiale ha condotto alla progettazione di un nuovo luogo sacro per la popolazione.

Clinical features and practical diagnosis of bullous pemphigoid

Bullous pemphigoid (BP) represents the most common autoimmune subepidermal blistering disease. BP typically affects the elderly and is associated with significant morbidity. It has usually a chronic course with spontaneous exacerbations. The cutaneous manifestations of BP can be extremely protean. While diagnosis of BP in the bullous stage is straightforward, in the non-bullous stage or in atypical variants of BP signs and symptoms are frequently non-specific with eg, only itchy excoriated, eczematous, papular and/or urticarial lesions that may persist for several weeks or months. Diagnosis of BP critically relies on immunopathologic examinations including direct immunofluorescence microscopy and detection of serum autoantibodies by indirect immunofluorescence microscopy or BP180-ELISA.

Novel approaches to therapy of hypereosinophilic syndromes

There has been recent progress in the understanding of the pathogenesis of the hypereosinophilic syndromes (HES). This led to the distinction of subgroups, in which the underlying cause has been identified. Consequently, new treatment options became available, such as imatinib and mepolizumab, which proved to be promising. This article summarizes these new pharmacologic approaches to the therapy of HES.

The basophil activation test in immediate-type drug allergy

Diagnosis of drug allergy involves first the recognition of sometimes unusual symptoms as drug allergy and, second, the identification of the eliciting drug. This is an often difficult task, as the clinical picture and underlying pathomechanisms are heterogeneous. In clinical routine, physicians frequently have to rely upon a suggestive history and eventual provocation tests, both having their specific limitations. For this reason both in vivo (skin tests) and in vitro tests are investigated intensively as tools to identify the disease-eliciting drug. One of the tests evaluated in drug allergy is the basophil activation test (BAT). Basophils with their high-affinity IgE receptors are easily accessible and therefore can be used as indicator cells for IgE-mediated reactions. Upon allergen challenge and cross-linking of membrane-bound IgE antibodies (via Fc-epsilon-RI) basophils up-regulate certain activation markers on their surface such as CD63 and CD203c, as well as intracellular markers (eg, phosphorylated p38MAPK). In BAT, these alterations can be detected rapidly on a single-cell basis by multicolor flow cytometry using specific monoclonal antibodies. Combining this technique with in vitro passive sensitization of donor basophils with patients' serum, one can prove the IgE dependence of a drug reaction. This article summarizes the authors' current experience with the BAT in the diagnostic management of immediate-type drug allergy mediated by drug-specific IgE antibodies.

In vitro tests in drug hypersensitivity diagnosis

The diagnosis of a drug hypersensitivity reaction (DHR) is a challenging task because multiple and complex mechanisms are involved. Better understanding of immunologic pathomechanisms in DHRs and rapid progress in cellular-based in-vitro tests can help to adjust the correct diagnostic strategy to individual patients with different clinical manifestations of drug allergy. Thus, drug hypersensitivity diagnosis needs to rely on a combination of medical history and different in vivo and in vitro tests. In this article, the authors discuss current in vitro techniques, most recent findings, and new promising tools in the diagnosis of T-cell-mediated drug hypersensitivity.

Approach to the patient with drug allergy

Drug allergies are adverse drug reactions mediated by the specific immune system. Despite characteristic signs (eg, skin rash) that raise awareness for possible drug allergies, they are great imitators of disease and may hide behind unexpected symptoms. No single standardized diagnostic test can confirm the immune-mediated mechanism or identify the causative drug; therefore, immune-mediated drug hypersensitivity reactions and their causative drugs must be recognized by the constellation of exposure, timing, and clinical features including the pattern of organ manifestation. Additional allergologic investigations (skin tests, in vitro tests, provocation tests) may provide help in identifying the possible eliciting drug.
