Persistence, severity and reactivity thresholds in fish allergic patients sensitized to parvalbumin.

Background: Fish allergy affects children and adults worldwide and there are transient and persistent phenotypes.

Objective: We aimed to analyze persistence, severity and reactivity thresholds in challenge-confirmed fish allergic patients sensitized to parvalbumin.

Methods: Patients 12-65 years-old reporting immediate reactions to fish, with fish skin prick test ≥5 mm and IgE to cod and carp β-parvalbumins ≥0.

Development of a hypoallergenic recombinant parvalbumin for first-in-man subcutaneous immunotherapy of fish allergy.

Background: The FAST (food allergy-specific immunotherapy) project aims at developing safe and effective subcutaneous immunotherapy for fish allergy, using recombinant hypoallergenic carp parvalbumin, Cyp c 1.

Objectives: Preclinical characterization and good manufacturing practice (GMP) production of mutant Cyp (mCyp) c 1.

Methods: Escherichia coli-produced mCyp c 1 was purified using standard chromatographic techniques.

FAST: towards safe and effective subcutaneous immunotherapy of persistent life-threatening food allergies.

The FAST project (Food Allergy Specific Immunotherapy) aims at the development of safe and effective treatment of food allergies, targeting prevalent, persistent and severe allergy to fish and peach. Classical allergen-specific immunotherapy (SIT), using subcutaneous injections with aqueous food extracts may be effective but has proven to be accompanied by too many anaphylactic side-effects. FAST aims to develop a safe alternative by replacing food extracts with hypoallergenic recombinant major allergens as the active ingredients of SIT.

Performance assessment of four 64-slice computed tomographic devices for a typical clinical protocol.

Objective: To compare the performances of four 64-slice CT devices, as regards radiation dose and image quality.

Methods: Effective dose was measured with thermoluminescent dosimeters in an Alderson Rando phantom (Alderson Research Laboratories, New York, NY). Quantitative image quality was evaluated in a Catphan 600 phantom (The Phantom Laboratory, New York, NY) using 3 parameters (modulation transfer function, contrast-to-noise ratio, and figure of merit).

Non-traumatic abdominal emergencies: imaging and intervention in acute pancreatic conditions.

Pancreatic emergency, unrelated to traumatic events, can occur as a consequence of the more significant pancreatic pathologies (acute and chronic pancreatitis, tumors) or of the interventional or surgical treatment carried out as therapy for the above-mentioned lesions. Acute pancreatic conditions are represented by pancreatic infections, the involvement of organs, structures, and adjacent spaces within the pancreatic disease, and, lastly, vascular complications. Acute pancreatic conditions are common in pancreatic diseases and can be catastrophic; even if there is a gamut in the severity of clinical presentation, each can be potentially life threatening.
