Organizzazione, strutture e qualità dell'assistenza al parto.
No full textL'Autore illustra in dettaglio gli eventi nei quali si possono creare condizioni di rischi feto-neonatale, dall'accettazione della gestante al trasporto del neonato, e i fattori condizionanti il possibile rischio feto-neonatale: personale medico e paramedico, strutture ambientali, fattori igienici, attrezzature diagnostiche e di monitoraggio, strumentario chirurgico, attrezzature di rianimazione e di trasporto del neonato. Tutti questi fattori possono in qualche modo contribuire allo stato di sofferenza fetale se non addirittura alla morte.Pertanto, il riscontro autoptico diventa di primaria importanza per identificare l'esatta causa di morte e il patologo deve essere in possesso dei dati clinici e di laboratorio, delle caratteristiche tecnico-organizzative delle strutture in cui è avvenuto il travaglio e dell'assistenza al neonato, per espletare le sue indagini nel modo più esauriente e soprattutto efficace per la profilassi futura

The pineal gland and reproduction
No full textThe hormonal activity of the pineal gland is influenced by both the dark-light cycle and the seasonal cycle, causing it to play an important role in the neuroendocrine control of reproductive physiology, This is especially evident in seasonally breeding animals, in which reproductive function is clearly influenced by seasonal variations in the duration of night and day. Humans are not seasonal breeders, Nevertheless, seasonal fluctuations have been described in human reproduction, and the pineal gland also appears to exert an important role in the neuroendocrine regulation of human reproductive physiology, There is evidence that the epiphysis is involved in the control of sexual maturation. In rats, the maternal pineal appears to influence the gonadal and genital development and function of offspring; this hypothesis has yet to be confirmed in humans, The pineal apparently influences human reproductive function not only at the hypothalamic-pituitary level, by inhibition of the hypothalamic pulsatile secretion of gonadotrophin-releasing hormone, but also at the gonadal level, where melatonin receptors have also been found, In addition, melatonin is reported to increase serum prolactin concentrations in both rats and humans, It has been suggested that melatonin is involved in the control of menstrual cyclicity
The evolution of estroprogestative contraception: Analysis on the reduction or suppression of side-effects
No full textThe advances achieved by scientific research about contraception estroprogestinic contraception have lead to a better knowledgeof the risk factors connected to the use of oral contraceptives (O.C.) and trough the years, the change of their hormonal components dosesand of the type of progestin. These advances, together with the selection and monitoring of the patients who can use the pill have been accompanied by an evolution of its riskk. O.C. risks basically include neoplastic, cardiovascular, metabolic, and reproductive risks. This article presents a review of the most important studies conducted about such possible relations. The Authors conclude that the progress achieved in the hotmonal contraception has allowed to reduce greatly and, in some cases, to annul its risks. therefore, proper information is needed to explain that the pill, administered under medical control, is a safe drug and that many fears for its uses are no more justified
