Growth hormone-releasing hormone and somatostatin in normal and tumoral human pituitaries.

In order to further understand the role of endogenous pituitary neuropeptides in pituitary hormonal content and secretion, GHRH, SRIH and GH contents were quantified in GH adenomas obtained from acromegalic patients with plasma GH levels either high (greater than 5 micrograms/l, range 11 to 550 micrograms/l, n = 11) or in the normal range (less than 5 micrograms/l, range 1 to 3.3 micrograms/l, n = 4). Values were compared to those found in normal human pituitaries. No relationship was found between GHRH content and plasma GH or between SRIH and GH content when considering together adenomas and normal pituitaries. Results showed that there is a positive relationship between GHRH and GH content: when GHRH content is high, GH content is also high (normal pituitaries and GH adenomas of acromegalic patients with high plasma GH) and when GHRH content is low, GH content is also low (GH adenomas of acromegalic patients with plasma GH in the normal range). Conversely, SRIH content is negatively related to plasma GH levels: when SRIH is present, plasma GH is in the normal range; when SRIH is undetectable, plasma GH is high.

[Secondary side effects of corticosteroids and the management of corticosteroid therapy].

The side effects of glucocorticoids are the result of their biological effects and closely related to the dose administered and the duration of treatment. Whilst excessive amounts may result in the development of a clinical and biological Cushings syndrome, there exists also the problem of avoiding acute adrenal insufficiency when corticosteroids are stopped after a prolonged period of administration or during substitutive therapy for adrenal insufficiency. Aspects requiring surveillance are discussed.

[Proceedings: Prolactin adenoma revealed by gemellary? pregnancy after clomiphen therapy. Hypophysectomy during 5 th month of pregnancy (author's transl)].

A 25 year old woman had galactorrhea and secondary amenorrhea since her first pregnancy at 20 years. After several treatments with Clomiphene, menses reappeared for 2 months and she became pregnant. At admission, she was in her 4th pregnancy month and had headaches and bitemporal hemianopsia. Hypophysectomy was performed during 5th pregnancy month. Prolactin adenoma with hemorragic lesions was found. Parturition of normal twins occurred 8th month. Partial hypophyseal recovery took place for the following 2 years, but hyperprolactinemia reappeared too.
