This prospective case-control study was designed in a university hospital. Thirty-two turkish postmenopausal women were evaluated for the associations between obesity, parity, age, age at menarche, age at menopause, total lactation period and dysplasic mammographic patterns. We found an increasing trend of dysplasia with increasing age at menarche. This association contradicts the well established one for breast cancer. The effects of parity and total lactation period on dysplasia were similar. Although nulliparity had some protective effects on dysplasia, relative risk (RR) increased to some extent with an increase in parity and lactation period. Later menopause and older age were associated with an increase risk of dysplasia, whereas an apparent protection was given by greater body mass index. Onset of the menopause increases the risk of dysplasia and the estrogenic milieu may have some role in the initiation and progression of dysplasia.

The plasma concentrations of prolactin and cortisol were measured by radioimmunoassay during oxytocin induced labour, spontaneous labour, delivery and postpartum 24 h. The parturients were divided into three groups. The first group was given oxytocin for the induction of labour, the second group was also given oxytocin for the induction of labour and 100 mg of meperidine was administered intramuscularly for relief of pain and anxiety, and the third group was the control group with normal parturients who did not receive any medication. The prolactin levels showed a fall during labour in all the groups, but this fall was more marked in the first group where stress was evident. The concentrations of cortisol tended to increase during labour and reached a maximum at delivery in all three groups but in the meperidine group this level was significantly lower than the first and control groups. These results give further support to the hypothesis that maternal stress leads to a reduced concentration of prolactin and increased concentration of cortisol whereas relief of pain and maternal anxiety with meperidine lessens both effects.

In the natural menopause group we found inverse correlations between bone mineral density (BMD) vs. menopausal duration; BMD vs. body mass index (BMI) and BMI vs. inorganic phosphate (Pi), borderline correlations between weight vs. thyroxin (T4) and weight vs. luteinising hormone (LH) and a positive correlation between androstenedione (D4A) vs. urinary calcium (Uca). In the surgical menopause group we found some negative correlations (BMD vs. menopausal duration, BMI vs. Pi; BMI vs. dehydroepiandrosterone sulphate (DS), weight vs. DS and cortisol vs. Uca) and some positive correlations (BMD vs. free testosterone (fT), BMD vs. calcium (Ca), and BMD vs. Uca). We concluded that the serum hormone levels we measured were not useful markers of current bone mineral status.

Çalışmanın yapıldığı yer: Dokuz Eylül Üniversitesi Tıp Fa kültesi Kadın Hastalıkları ve Doğum Anabilim Dalı, izmir. Olgu sunumu: Bir yıl önce spontan gebe kalan renal trans plant hastası terme kadar takip edilmiş ve doğurtulmuştur. Sonuç: Bu hastalarda prognoz, multidisipliner bir takip ile semptomların erken tanı ve tedavisine dayanmaktadır.

Research paper thumbnail of Ovarian Pregnancy; Relationship to an Intrauterine Device

The incidence is 0.5 to 3% of all ectopic gestations (1). In contrast to patients with tubal pregnancies, traditional risk factors, such as pelvic inflammatory disease and prior surgical procedure upon the pelvis, may not play a role in the aetiology. In the 2 cases reported here, it seems that using an intrauterine contraceptive device was an important factor.
