[Adrenal function and lipid metabolism in asthmatic children treated with budesonide].

Objective: To assess the effect of low doses of inhaled budesonide on the adrenal function and lipid metabolism of asthmatic children.

Material And Methods: The study included 10 asthmatic children (mean age, 8.8 years) treated with inhaled budesonide (200-300 micrograms/day) for a period longer than 3 months (group A); 15 asthmatic children (mean age, 7.

Cryptorchidism: treatment with human chorionic gonadotropin--a Venezuelan experience.

The study comprised 323 cryptorchidic boys, between 6 months and 14 years of age (mean age 5.68 years) with 440 maldescended testes. Testicular position was graded as inguinal low or prescrotal (I), inguinal middle (II), inguinal high (III), and abdominal testes (IV).

Effects of thyroid status on pituitary gonadotropin and testicular reserve in men.

This investigation was conducted to evaluate the effect of thyroid dysfunction on the pituitary-gonadal axis. Ten men with Graves' disease and 5 hypothyroid patients were studied; 10 normal males were studied as a control group. In untreated conditions hyperthyroidism was associated with a normal serum-free testosterone concentration, an increased serum of 17OHP levels, a reduced testosterone response to hCG stimulation, and a hyperresponse of LH to GnRH.

[Esophageal varices as a cause of upper digestive hemorrhage in cirrhotic patients: clinical and epidemiologic investigation].

We studied the association between esophageal varices as the course of upper gastrointestinal bleeding and hepatic cirrhosis. 154 patients were admitted 43 patients in which esophageal varices bleeding was diagnosed were considered "CASES". 111 patients in which the source of bleeding was different (peptic ulcer, duodenitis, gastritis or tumor) were considered "CONTROL".

[Early stress tests following an uncomplicated myocardial infarct: a comparison between symptom-limited and submaximal tests].

To compare the diagnostic and prognostic usefulness of symptom-limited versus load-limited submaximal stress testing, 76 patients, during the first week post acute non-complicated myocardial infarction, were submitted to a symptom-limited Naughton-modified protocol stress test. At 2 METs, 3 METs and maximal effort levels, the tests were classified as positive or negative following the currently used criteria. After a mean follow-up of 15 months, the symptom-limited protocol showed the best sensitivity (95%), specificity (78%), positive (64%) and negative (98%) predictive value, and also the highest risk ratio (27.
