[The influence of medical informed consent discussion on postoperative satisfaction and quality of life of patients with uterine fibroids after myomectomy or hysterectomy]. / Der Einfluss des ärztlichen Aufklärungsgespräches auf die postoperative Zufriedenheit und Lebensqualität von Patientinnen mit Uterus myomatosus nach Myomenukleation oder Hysterektomie.

The surgical treatment of uterine fibroids represents an important column in the therapy of this disease. Aim of this study was to find out preoperative factors that influence the treatment success of a minimal-invasive surgical -therapy.In a retrospective study 228 patients were assessed. Measures comprised questions on the decision for surgery, satisfaction with the treatment, and the EQ-5D as a measure of QoL.The sample revealed an overall satisfaction with treatment and high QoL. A better postoperative contentment and QoL in patients who felt well informed about the surgical methods and who felt secure with their decision for a specific surgery was found.Regardless of the surgical method, the preoperative consultation and the certainty of the decision turned out to be determinants of the patients' postoperative contentment and QoL. The counseling gynecologist has an essential part in the patients' decision for the treatment.

[Fertility and cancer--outlining of the issue]. / Fertilität und Krebs--Skizzierung des Problemfeldes.

The subject "fertility and cancer" becomes increasingly important due to a steadily improving of survival rates of young patients. It is essential for patients being informed about possible consequences of their cancer disease and required medical care concerning a prospective parenthood. Any loss of fertility implies an additional devastating burden and rearrangement of the concept of life regarding to family planning. A transparent conversation about carefully considered treatment options of fertility preservation should be offered to the patients. Expertise on the part of oncologists about possible risks and a good physician-patient-communication are indispensable. Today fertility preserving strategies are available for females and males and could symbolise a bridge in the future. Prospective parenthood plays an important role for cancer patients. For using all opportunities of fertility preserving strategies offered to every patient, a close cooperation between oncologists and specialists in reproductive medicine is needed.

Size effects in ferroelectric PbTiO3 nanomaterials observed by multi-frequency electron paramagnetic resonance spectroscopy.

Lead titanate (PbTiO3) micro- and nanocrystalline powders have been prepared from metallo-oranic precursor through combined polymerisation and pyrolysis (CPP). The enhanced liquid-precursor based version of the cpp route in combination with soft milling enables an adjustment of the mean particle size up to 5 nm. A multi-frequency (X, Q, and W band) electron paramagnetic resonance study of Cr-doped micro- and nanocrystalline PbTiO3 samples was performed. Three Cr3+ centers (C1, C2, and C3) with different axial Zero Field Splitting (ZFS) parameters were identified in microcrystalline samples. The center C1 is similar to that observed in previous X band single crystal and ceramic sample measurements. The superposition model by Newman and Urban was applied to translate the ZFS data of these centers into local Cr3+ displacements inside the distorted oxygen octahedra of the microcrystalline PbTiO3 lattice. In the nanocrystalline powders only the center C1 was observed. Its EPR spectra in dependence on the mean particle size were fitted using a spin-Hamiltonian in which a Gaussian distribution of ZFS terms was assumed. The variation of the mean value of ZFS parameter D and distribution width deltaD was determined and the critical particle size of the size-driven phase (tetragonal-cubic) transition was estimated. In nanocrystalline powders with mean particle size d < d(cr) the tetragonal C1 spectrum is not more detectable. A new Cr3+ center spectrum, C4, consisting of a single line with an isotropic g-factor is detectable allowing the cubic phase in the nanomaterials to be quantified. Further, temperature dependent EPR measurements were made which allowed the variation in Curie temperature with mean particle size to be determined.
