RESUMEN
Twenty women with Chlamydia trachomatis genitourinary infection were treated with oral enoxacin 800 mg/day in two divided doses for 12 days starting on day 1 of the menstrual cycle. A physical examination was performed before the start and 28-30 days after the end of the treatment. At the final examination cultures of urethral and endocervical swabs and endometrial samples were negative in all cases, demonstrating that Chlamydia trachomatis infection had been eradicated. No significant results were obtained at serologic evaluation with the indirect immunofluorescence method to show specific IgM, IgG and IgA antibodies. In the four women with subjective symptomatology this was improved by the treatment with enoxacin. Only two patients presented mild side effects (headache, tachycardia, nausea). Enoxacin seems therefore a very effective and well tolerated drug in the treatment of Chlamydia trachomatis genitourinary infection.

Treatment of coagulation deficiencies with high dosages of the missing factor is a source of continuous diffusion of homologous proteins that could modify the normal immunological profile. We have performed immunologic studies on 24 children with ages ranging from 1 - 16 years with severe classical hemophilia and 1 child with von Willebrand's and on a control of 19 age-matched healthy children. Our preliminary data show no statistically significant alterations in the basic immunological profile between normal children and those with hemophilia. Nor were there any differences among the hemophilic patients on the various transfusional regimes. Considerations are made on the reasons for the discrepancies between our results and those on adults presented in the literature.

The effect of arginine infusion on blood sugar and plasma levels of growth hormone and glucagon has been studied in children with clinical diabetes mellitus and in obese children with normal carbohydrate tolerance. Basal levels of plasma GH are significantly lower in obese children than in diabetics and controls; in obese subjects the increment of GH is significantly lower than in diabetics and controls. Basal plasma glucagon levels are comparable in all three groups despite the high sugar levels in diabetic patients. After arginine infusion there is a significant rise in glucagon levels without significant differences between the three groups.

In nine children with clinically overt insulin-dependent diabetes mellitus the authors injected cyclic somatostatin (3 mug./kg. bolus, followed by infusion of 13 mug./kg. in 60 minutes) and measured blood glucose, plasma growth hormone, and glucagon concentrations throughout the infusion. The rapid administration produced no significant changes of these parameters. With the prolonged infusion there was a significant reduction of blood glucose from a mean of 148 +/- 19.7 to a mean of 88.5 +/- 18.1 mg./100 ml. (P less than 0.005) and of plasma glucagon from a basal mean of 33.3 +/- 2.4 to a minimum mean of 22.1 +/- 1.7 pg./ml. (P less than 0.01). There was a statistically significant correlation between the two parameters (0.01 less than P less than 0.05). Plasma GH values also diminished during the infusion, but the reduction was not statistically significant. These results show that somatostatin lowers blood glucose concentrations as a secondary effect of inhibition of glucagon secretion. Somatostatin is not suitable for therapy in diabetes. We speculate that a similar substance with a more prolonged and specific action on glucagon might prove of practical value in the treatment of diabetes mellitus.

The effect of alpha1-24-corticotropin-Zn on the results of pituitary stimulation tests (moderate standardized physical exercise, arginine infusion, insulin-induced hypoglycemia) was studied in 27 prepubertal children with non-endocrine retardation of growth and development. After administration of 1 mg alpha1-24-corticotropin, the basal blood glucose and plasma cortisol levels rose significantly. However, the growth hormone increase after the three stimulation tests was significantly lower than without the corticotropin injection. The results demonstrate the inhibiting effect of alpha1-24-corticotropin on growth hormone secretion.

The elevated level of growth hormone after moderate standardized physical exercise was compared with that induced by intravenous arginine infusion and by insulin induced hypoglycemia in children with normal pituitary function. Tests were performed on 49 prepubertal children (34 boys and 15 girls); in 42 cases the increase was significant for all three tests, in 5 cases the response was minimal after insulin stimulation but normal after arginine and physical exertion; in 1 case arginine produced no response but the other tests were positive; in 1 case there was a response to arginine but none to insulin or physical exertion. The results indicate that frequently more than one test is necessary for the diagnosis of normal pituitary function; physical exertion being a physiologic test, is simple to perform, acceptable to the children and without side effects. It appears the test of first choice because it can be used in patients seen ambulatorily, other tests being performed in case of doubt or negative response.

The effect of muscular exertion of moderate intensity on blood sugar (BS), plasma levels of growth hormone (GH), glucagon, and cortisol (F) has been studied in endocrinologically normal children with short stature and compared with children with clinical diabetes mellitus and obese children with normal and diminished carbohydrate tolerance. In diabetic children, physical exertion induces a rise in plasma GH levels comparable to that in controls; in obese children with normal or with diminished glucose tolerance, the rise is considerably smaller. Physical exertion caused no change in F levels in the groups tested, although basal level in the obese children was significantly higher than in the controls. Basal glucagon levels were similar in all groups and showed no change on physical exertion. The behavior of GH and glucagon in diabetic children was comparable to that in the controls even where blood sugar level was high.
