Rheumatoid iliopsoas bursitis presenting as unilateral leg edema

A 66-year-old woman with rheumatoid arthritis presented with unilateral leg edema attributable to an enlarged iliopsoas bursa with presumed impedance of lymphatic drainage. The adjacent hip joint was not severely involved by arthritis. Ultrasonography and computed tomography were used to delineate the bursal mass and demonstrate communication with the joint space.

Tinea capitis. A clinicoetiologic correlation

A study of 50 patients with tinea capitis revealed that it affects school children of low socioeconomic status. Clinical diagnosis of grey patch, black dot, seborrheic, kerion, and pustular inflammatory varieties was made. In all, 37 cultures were positive for dermatophytes, wherein most were Trichophyton violaceum. Some grew T. rubrum, T. mentagropytes, and T. verrucosum. A correlation between the clinical variants and fungi was also attempted.

Method of determining kidney position as guide for percutaneous nephrostomy

Computed tomography scans were used to assess the distance between the skin and the collecting system in 256 kidneys in 128 adult patients of various heights and weights. Body surface area correlated well with kidney depth. A graph is presented that can be used to calculate kidney depth.
