In mouse models, Sun et al. found that this symptom is in part mediated by GRPR binding. Fatigue and a severe, generalized form of this symptom are often the presenting symptoms of a disease that is characterized by the presence of anti-mitochondrial antibodies (-5[1])and treated with urso·deoxy·cholic (0[1]-5[1])acid. This symptom characterizes a “polymorphic (-5[1])eruption” that occurs during the third trimester of pregnancy. This symptom’s “aquagenic” form sometimes occurs after individuals with (*) poly·cythemia vera take hot showers. This symptom dominates a parasitic infection diagnosed by the “scotch tape test.” Topical (10[1])permethrin is used to treat infections by several organisms that cause this sensation, (10[1])including Pthirus (10[1])pubis and Pediculosis pedis. This sensation accompanies (10[1])a contact dermatitis rash (10[2])caused by urushiol. For 10 points, calamine lotion (10[1])is used to relieve what uncomfortable sensation caused (10[1])by poison ivy? ■END■
