[Gonadal, hormonal and spermatic function in patients treated for cryptorchidism].

This paper studies the gonadal-hormonal and spermatic function of 48 adults (over 18 years old) who were treated in childhood for cryptorchidism by medical, surgical or both treatments. We measure plasmatic levels of FSH, LH, testosterone and prolactin of 34 patients and sperm samples of 31 patients. The testicular hormonal function was not disturbed except in four patients with high levels of prolactin (> 20 ng/ml) without symptoms. The spermatic function was disturbed in bilateral cryptorchidism mainly. The better sperm quality and testicular volume were at patients treated with hormonal treatment before surgical treatment.

[Pituitary apoplexy in 2 hypophyseal tumors].

Hypophyseal apoplexy is not always easy to confirm morphologically or analytically. We present a patient with Cushing's syndrome due to hypophyseal apoplexy and optochiasmic pachyarachnoiditis which produced serious visual alterations. The adenoma necrotized behind an area of hypophyseal apoplexy which cured the patient's Cushing's disease. The second case was admitted with hypophyseal apoplexy, presenting hypophyseal tumoration with signs of hemorrhage and subsequent panhypopituitarism.

[Suprarenal carcinoma of an unusual size].

Suprarenal carcinoma is an unusual entity, rarely surpassing 4,000 gr. In general, tumors of such big size are not functional. We present a case of a 31-years-old woman with a suprarenal carcinoma weighting 5,200 gr, in which hormonal production was clinically and biochemically demonstrated.

[Parathyroid insufficiency syndrome. Two new cases: type Ia pseudohypoparathyroidism and pseudo-idiopathic hypoparathyroidism].

Two new cases with parathyroid insufficiency syndrome are described. The first one is a seven year and 6 months old male with Pseudohypoparathyroidism Type Ia, who has presented: hypocalcemia, hyperphoforemia, increased PTH and TSH, prolactin decreased and Albright hereditary osteodystrophy phenotype. The second one in a six year and four months old female with Pseudo-idiopathic hypoparathyroidism who has presented: hypocalcemia, hyperphosforemia, increased PTH, without any hormonal disturbances nor dysmorphias. Ellsworth-Howard test with 50 micrograms of 1-34 hPTH is made in both, remarking the different renal response about phosphaturia and plasmatic, urinary and nephrogenic cyclic AMP. The treatment is performed in both with calcitriol and oral calcium (L-Thyroxine is associated for the first patient). Biochemical disturbances are normalized. Other parathyroid insufficiency syndrome are revised.
