[Empty follicle syndrome as cause of unsuccessful in vitro fertilization]. / "Ures" tüszö szindróma, mint a sikertelen in vitro fertilizáció egyik oka.

The authors report a case, where ultrasound guided transvaginal follicle aspiration was carried out for oocyte retrieval during the source of in vitro fertilization. Despite the favourable situation described by ultrasound and prognosed by serum hormone levels aspiration of oocytes proved unsuccessful even after lavage of follicules. The authors give an overview of the literature of "empty" follicle syndrome, its possible aetiology and methods of treatment.

[Can the storage time be limited for cryopreserved pre-embryos?]. / Korlátozható-e a humán préembriók fagyasztva tárolásának idötartama?

The authors discuss about the questions connected with the time of the storage of the human cryopreserved preembryos. After approaching the different interest of the participants and giving the variable international statements the authors are preparing their suggestion for the limitation of the storage of the cryopreserved human preembryos.

Ageing and problems in differential diagnosis of psychoorganic syndromes.

Depressive syndrome was investigated in 132 psychiatric and neurologic patients by Zung's self-rating depression scale. The dexamethasone suppression test (DST) was carried out in 62 patients. Visual evoked potentials (VEP) (stimulation with flash (F-VEP) and pattern (P-VEP)), serum levels of LH, FSH, prolactin, ACTH, estradiol and cortisol were measured in 15 female patients between 85 and 94 years of age. Abnormal DST results indicated depression rather than dementia. P-VEP latencies correlated with cognitive symptoms, while F-VEP latencies correlated with affective symptoms. Gonadotropin levels were lowered in senility in comparison with the climacteric period of life. Depressive, anxious, cognitive, anorexic, sexual and disturbed diurnal mood changes syndromes could be separated by factor analysis. The severity of the cognitive depressive syndrome correlated negatively with estradiol serum levels. The total scores of Zung's self-rating depression scales correlated positively with ACTH and negatively with FSH serum levels.
