Transient ovarian testosterone and androstenedione hypersecretion: a cause of virilization or premature pubarche in prepubertal girls.

In 2 girls with signs of androgen overproduction, the usual causes were excluded. Patient 1 (3.6 years) presented with hypertrophy of the clitoris, patient 2 (7.8 years) with pubic and axillary hair. Urinary steroids and plasma dehydroepiandrosterone, 17-hydroxyprogesterone and estradiol were normal, but testosterone and androstenedione elevated in both cases. Echography showed polycystic ovaries. Testosterone and androstenedione returned to normal after laparotomy and removal of ovarian cysts in patient 1, and spontaneously in patient 2, in whom puberty started later appropriately for bone age.

Treatment of pubertal gynaecomastia with testolactone.

22 Boys with pubertal gynaecomastia (age 15.9 +/- 1.9 years) were treated with testolactone (450 mg daily by mouth) for 2 to 6 months without side-effects. The mean breast gland diameter regressed from 4.4 to 3.3, 3.2 cm, and 1.7 cm at 2, 4, and 6 months, while pubic hair and testicular volume progressed normally. Plasma androstenedione increased from 5.4 to 73.1 nmol/l. Testosterone, DHEA, and oestrone increased less, and oestradiol remained unchanged. Androgen/oestrogen ratios increased (most marked change: androstenedione/oestrone from 15 to 140). LH (basal and maximum after LHRH) did not change, but FSH increased somewhat (basal 133 to 173, maximum 225 to 269 micrograms/l). Prolactin remained unchanged. It is concluded that testolactone, an inhibitor of steroid aromatization, is an effective and safe medical treatment for pubertal gynaecomastia.

Dissociation between adrenarche and gonadarche in two longstanding hypothyroid youngsters.

An evident dissociation between adrenarche and gonadarche was found in two longstanding hypothyroid youngsters, one male and one female, with advanced gonadal development and absent sexual hair. This discrepancy rapidly vanished after the institution of thyroxine substitutive treatment. These case reports underline the important relationships existing between thyroid function and endocrine systems involved in the regulation of adrenarche and gonadarche.

Sensorineural deafness in congenital hypopituitarism with severe hypothyroidism.

Marked sensorineural hearing loss was documented in an 18-year-old boy with untreated congenital anterior panhypopituitarism. The clinical manifestations of the hypothalamic thyroid failure were unusually severe in this patient. Seemingly this is the first case report of perceptive-cochlear deafness in a subject with non primary congenital hypothyroidism.

True precocious puberty: a long-term complication in children with shunted non-tumoral hydrocephalus.

In 4/37 (10.8%) children, adolescents and young adults with successfully shunted hydrocephalus, puberty occurred or was occurring precociously, at an age ranging from 7.5 to 8.6 years, with a consequent impairment of their effective or predicted adult height as compared to the familial target height. All four patients had undergone a surgical intervention for the insertion of a ventricular-atrial or a ventricular-peritoneal shunt during the first year of life; since the last surgical shunt revision (at the age of 5 years) no relapse of hydrocephalus had been recorded. The authors conclude that precocious puberty is to be regarded as a not infrequent long-term complication in patients with successfully shunted hydrocephalus.
