ABSTRACT
OBJECTIVE: To identify diagnosis, therapeutic and histological particularities of ovarian fibro-thecomas. STUDY DESIGN: A retrospective study of 12 patients who underwent surgical treatment for ovarian fibro-thecoma between January 1994 and December 1999 was reported. Clinical, ultRasonographic, tumour marker, therapeutic and histologic data were analysed. RESULTS: Mean age of patients was 46.83 years. Three patients were in perimenopausal period and six were menopausal. Ultrasonographic findings were: ovarian echogenic tumor in six cases, hypoechogenic tumor in three cases, mixed tumor in three cases and anechogenic tumour in one case. CA 125 level measured in 11 cases was normal. Nine patients underwent laparotomy. Three patients underwent laparoscopy, however, one was converted to laparotomy due to a suspected tumour. A conservative treatment was performed for three patients and radical treatment for nine patients. Histological findings were eight fibromas and five fibro-thecomas. CONCLUSION: Ovarian fibro-thecoma is uncommon. These lesions occur often in perimenopausal and menopausal patients. Clinical, ultrasonographic and tumour marker data remains the best preoperative approach currently available for ovarian tumours. However, the diagnosis remains histological. Tumorectomy is well indicated for young patients, however radical treatment is indicated for perimenopausal and menopausal patients.

A preliminary investigation of electric dipole reorientability in human tooth enamel (TE) in comparison to that in hydroxyapatite (OHAp) has been made with the fractional-polarization form of the thermally stimulated currents (TSC) method. The reorientable dipoles are the structural OH-ions. The OHAp exhibited compensation phenomena at 211.5 degrees C and at 356 degrees C which are associated here with the hexagonal form becoming quasi-statically stabilized and dynamically stabilized, respectively, against the monoclinic form. TE specimens were pretreated at various temperatures. All showed the onset of cooperative motions that could quasi-statically stabilize the hexagonal form at the same temperature, approximately 212 degrees C, as did OHAp, even though the TE was already statically stabilized in the hexagonal form. Parts of the TSC spectra that did not conform to the 212 degrees C compensation changed progressively with pretreatment temperature. Loss of incorporated H2O is identified as the most probable cause of most of these changes. This work shows considerable promise for TSC as a tool for further quantitative investigation of TE.
