Photodynamic therapy for recurrent gynecologic malignancy: a report on 4 cases.

4 patients with recurrent gynecological malignancy were treated photodynamically, 4 d after sensitisation with intravenous meso-tetra(hydroxyphenyl)-chlorin (m-THPC) at a dose of 0.15 mg/kg bodyweight (total dose ranged from 12-15 mg). Light at 652 nm was derived from a KTP-Dye laser (Diasonic) and delivered superficially at a total light dose of 20 J/cm2 (power density of 100 mW/sec).

Bone mineral densitometry in dialyzed patients: quantitative computed tomography versus dual photon absorptiometry.

Reduced bone mineral density (BMD) increases risk of fractures, thus making it necessary to monitor patients suffering from chronic renal failure and consecutive disturbance of bone metabolism. In order to evaluate the reliability of available methods, bone mineral density of the lumbar spine assessed with single energy computed tomography (QCT) was compared with bone mineral density of the lumbar spine, femoral neck, Ward's triangle and trochanteric region measured by dual energy photon absorptiometry (DPA) in 45 hemodialyzed patients with a mean hemodialysis duration of 35 +/- 26 months (SD). Depending on the measurement site and method 4-34% of dialyzed patients suffered from reduced BMD (z-score < -2).

[Biochemical and immunohistochemical detection of epidermal growth factor receptor in breast and ovarian tissue].

The epidermal growth factor receptor (EGFR) was assessed in 52 breast and 46 ovarian biopsies by the radio ligand binding assay and/or the immunoperoxidase technique. A direct comparison of the two methods was undertaken in 27 breast and 32 ovarian biopsies. The results of both methods correlated positively (r = 0.
