OBJECTIVE To report a case of occupational asthma and urticaria due to the queen scallop (Chlamys opercularis) and king scallop (Pectin maximus). BACKGROUND A 40-year-old female worked in a shellfish-processing plant, handling king and queen scallops for 5 years. At the time of investigation, she described a 2-year history of work-related respiratory symptoms. METHODS Serial peak expiratory...

BACKGROUND Allergic sensitization and reactions to guinea pig (Cavia porcellus) have been well documented in laboratory animal handlers, primarily manifesting as rhinitis, conjunctivitis, and asthma. Severe allergic reactions, however, are rare. METHODS We report two patients with severe allergic reactions following non-occupational exposure to guinea pigs. The first patient, an 11-year-old f...

The allergen-specific IgE antibody was determined in 20 men and 120 women with psoriasis and the results were correlated with a history of current and previous allergic disease. Allergic disease was reported in 21% of the patients, but a positive RAST test was obtained in 44%. In chronic plaque-type psoriasis a positive RAST test was significantly more common (58%) than in active psoriasis (22%...

The extraction of a parametric global motion from a motion field is a task with several applications in video processing. We present two probabilistic formulations of the problem and carry out optimization using the RAST algorithm, a geometric matching method novel to motion estimation in video. RAST uses an exhaustive and adaptive search of transformation space and thus gives – in contrast to ...

Patients and Methods: The aim of the present study was to evaluate the rate of SPT (skin prick tests) and RAST response to Der p in ato p ic children with AD. We have prospectively studied 176 children (93 mal es and 83 fe ma les) aged from 6 months to 7 years, and divided into four differ ent groups, including controls. We studied also their family history in the ac companying parents Results....

The predictions of M. Oaksford and N. Chater's (1994) optimal data selection (ODS) model for the reduced array selection task (RAST) were tested in 4 experiments. Participants tested a hypothesis, ifp then q, by selecting cards showing q or not q instances. In Experiment 1, where selections were made from different sized stacks of q and not q cards, as P(q) increased, not q card selections rose...
