Virilizing ovarian tumors are rare and can occur at any age. In postmenopausal women, they commonly present with signs of masculinization. These tumors should be suspected in any patient with virilization and high testosterone levels (>1ng/mL).

Analysis and prevention of recurrent goiter.

The current study was done to analyze our experience with recurrent goiter. Prevention must be stressed because reoperations of the thyroid gland present technical difficulties and are associated with an increased risk of hypoparathyroidism and permanent hoarseness. Nodular recurrences occurred in 36 of 1,456 patients (2.

[Corticotropic macroadenoma: clinical, hormonal, radiological and immunocytochemical study of 6 cases].

We report 6 cases of corticotroph macroadenomas which show heterogeneity of clinical and biological features (from Cushing's syndrome to silent adenoma) and heterogeneity of immunocytochemical staining. One patient reported on had skin hyperpigmentation and ACTH hypersecretion without clear abnormal adrenocortical function; we believe that this patient's plasma contained ACTH with very low bioactivity.

[Average level and variability of 24 hour blood pressure in the normotensive insulin-dependent diabetic patient].

This prospective study was designed: 1. to determine both the mean level and the intrinsic variability of blood pressure (BP) and heart rate (HR) in normotensive patients with insulin-dependent diabetes mellitus (IDDM), by using a nonambulatory recorder; 2. to look for a relationship between these parameters and the indices of diabetic target-organ damage.
