Relationship between Head Sway and Center of Foot Pressure Sway

We investigated the correlation between body sway and head sway in 64 healthy subjects who stood on a force-measuring platform. Each subject wore a helmet attached to a cephalograph and was asked to stand as still as possible on a platform with his feet close together for 60 sec. Subjects were asked to do this three times with their eyes closed and three times with their eyes open. We selected the test with the minimum sway for computer analysis of the sway path, sway area, ratio of anteroposterior/lateral components, sway velocity in each direction, averaged divisional frequency, and Romberg quotient. The movement of the head was significantly correlated with the center of foot pressure (COF) for the sway path, sway area, sway velocity, averaged divisional frequency, and the Romberg quotient. Our findings suggest that COF sway can be used instead of head sway to assess those five parameters.

Three Cases of Kimura's Disease.

We report 3 cases of Kimuras disease. All patients were male and ranged in age from 15 to 62 years. All cases showed eosinophilic granuloma in the salivary glands and regional lymphadenopathy. Case 1 was initially diagnosed with a malignant tumor by imaging findings (MRI, CT). This patient was treated with steroids only, showing a remarkable improvement. Case 2 with relapsing nephrotic syndrome has been kept free of granuloma by surgery and steroid hormone therapy. Case 3, who underwent surgical excision, experienced recurrence in spite of the continuous application of NSAID (nonsteroid anti- inflammatory drugs).
