Sphygmomanometry-evoked allodynia--a simple bedside test indicative of fibromyalgia: a multicenter developmental study.
One of the 2 classification criteria for fibromyalgia (FM) is the presence of tender points on specific anatomic sites. It has been established that these tender points reflect a state of generalized allodynia (defined as pain resulting from a stimulus that does not normally provoke pain). Patients with FM often describe pain elicitation during blood pressure testing (sphygmomanometry). ⋯ In this developmental study of patients attending rheumatology clinics, the generation of pain during blood pressure testing was strongly associated with the diagnosis of FM. This robust linkage probably reflects a tautologic phenomenon. A sine qua nonelement for FM diagnosis is the presence of tender points in discrete anatomic sites. These tender points in turn reflect a state of generalized mechanical allodynia that can be locally elicited by the cuff pressure during blood pressure testing. Sphygmomanometry is a simple bedside test that may be useful in the recognition of patients with FM. Blood pressure testing is a universal procedure in all clinical environments. Based on our results, we suggest searching for FM features in any person who has sphygmomanometry-evoked allodynia.

We report the case of a 28-year-old woman with systemic lupus erythematosus who, during a flare, suddenly developed febrile pancytopenia, hyperferritinemia, and abnormal liver function tests. Bone marrow aspiration confirmed hemophagocytic syndrome (HPS). ⋯ In febrile patients with lupus, pancytopenia together with very high ferritin levels should raise the suspicion of HPS and because this may be fatal, early bone marrow aspiration is mandatory for the diagnosis. The exclusion of concurrent infection as the cause of HPS is very important for the establishment of the right therapeutic strategy.
