Management of the amenorrhoea-galactorrhoea syndrome due to pituitary tumour is still controversial. However, in cases of pituitary prolactinproducing adenomas, ovulation and pregnancy are readily induced medically with bromocriptine. In our series of 14 patients conception occurred in all cases within 6 months of treatment. All of the 14 women had uneventful full term pregnancies and normal infants. Neither neurological nor visual symptoms appeared in these patients during their pregnancies. Lactation had no apparent effect on the growth of the pituitary tumour since radiological and neurological evaluations were unchanged. Prolactin levels for each patient following the termination of pregnancy and breast feeding were apparently diminished or similar to the prolactin levels obtained prior to treatment. This finding could add to the evidence that probably there was no further growth of the pituitary tumour. Three of the 14 women have had a second pregnancy without any complications. It is recommended that patients with microadenomas can be allowed to become pregnant on bromocriptine alone, provided that they are carefully supervised during pregnancy.There is major concern about the use of bromocriptine to induce ovulation in patients who desire to become pregnant and who harbour a pituitary tumour. This concern relates to the possible acceleration of growth of the prolactinsecreting tumour by the increasing levels of oestrogens that are secreted during

The overall prevalence of glucose abnormalities during pregnancy was 16%. GI in this group was associated to macrosomia at the same rate as GDM.

Prevalence of gestational diabetes was investigated in 693 pregnant patients between the 24th and 28th wk of gestation. A glucose screening test (GST) was performed with a 50-g glucose load, followed by a blood sample 1 h later. Patients with glucose levels greater than 140 mg/dl 1 h after the GST were scheduled for a full oral glucose tolerance test (OGTT). One hundred seven patients had an abnormal GST, and 30 patients (4.3%) were diagnosed as having gestational diabetes mellitus (GDM). The percentage of GDM increased significantly when glucose levels were greater than 180 mg/dl to a maximum of 84.61% when glucose levels were greater than 200 mg/dl. Also, patient age was directly related to GDM, which increased in incidence to 20% when patients greater than 26 yr had an abnormal GST. After delivery, newborn weights were compared between those born to mothers with GDM (n = 30) and those born to mothers with an abnormal GST (n = 77). Patients with an abnormal GST and normal OGTT had 12 (15.58%) macrosomic and 2 premature newborns. However, patients with GDM had 5 (16.66%) macrosomic and no premature newborns. Patients with a normal GST had 7.33% of the macrosomic newborns. There was no perinatal mortality in newborns of GDM mothers; only 1 of the 5 macrosomic newborns presented transient hypoglycemia. Evaluation of 26 GDM patients was possible after delivery, disclosing 3 (11.53%) with non-insulin-dependent diabetes mellitus and 5 (19.23%) with impaired glucose tolerance. These results showed 4.3% undetected GDM in our population and no differences in the proportion of macrosomic newborns between those born to mothers with GDM and those born to mothers with an abnormal GST.

We report a 14-year-old girl with primary amenorrhea and virilization. The chromosomal analysis showed a normal 46,XX female karyotype and the hormonal assays disclosed high serum levels of testosterone (T): 450 ng/dL (normal 5-90), dehidroepiandrosterone-sulfate (DHEA-S): 690 microg/dL (normal 30-450) and 17-hydroxiprogesterone (17-OHP) >20 ng/mL (normal <2). A pelvic ultrasound disclosed a small uterus and bilateral enlargement of the ovaries, a computed axial tomographic scan of the abdomen identified a large right mass in the adrenal gland and a norcholesterol-I 131 adrenal gammagraphy revealed a functional adrenal tumor. The histological analysis of the surgical removed tumor revealed and adrenal adenoma. After surgery, a steep decline to normal serum levels of T and DHEA-S was observed, remaining an elevated level of 17-OHP: 5.4 ng/mL. During the first three months of follow up, the hirsutism declined sharply and spontaneous mammary development occurred, remaining elevated the 17-OHP serum level: 4.8 ng/mL. Prednisone 5 mg/day, was initiated decreasing the 17-OHP to normal level: 1.4 ng/mL, appearing the menarche followed by cyclical menses. One year after surgery, prednisone was withdrawn during one week, and an ACTH test and HLA typing were done, disclosing a 17-OHP response of an heterozygote for adrenal hyperplasia, and identifying B65 a subtype of B14, and DR1, that are frequently associated to adrenal hyperplasia. Previous reports have informed silent adrenal tumors associated to adrenal hyperplasia, but this is the first report of a functional adrenal tumor associated to adrenal hyperplasia.
