Unlabelled: Clinical utility of the Overload Test with 50 g. of Oral Glucose (PSG) is evaluated, in 513 pregnancies with risk factors for diabetes. Of the 933 PSG which were made, 13.7% were positive (limit value: plasma glucose of much less than 150 mg/dl at 1 hour); the test were made after 20 weeks of gestation in 82.8% of the cases. Of the 128 positive PSG, 73 positive Oral Glucose Tolerance Test were obtained (O'Sullivan criteria). The prevalence of gestational diabetes found in this group was 15.2%. There was no difference on the most frequent risk factors (family history, obesity and macrosomia) between the general population in the study and the group of Gestational diabetes., Conclusion: PSG, because of its easy application, low cost and excellent tolerance is a test which should be included among the prenatal routine test as screening for gestational diabetes in our media.

Ninety-four patients with typhoid fever were treated, at random, with three therapeutic regimens: chloramphenicol alone, chloramphenicol plus oxyphenbutazone, and ampicillin plus oxyphenbutazone. The results are evaluated analyzing the body temperature graph and by serial blood had bone marrow cultures taken at intervals until they became negative. Bacteriologic diagnosis was confirmed by blood culture (39.3%) and/or bone marrow culture (77%). The mean duration of fever was 3.3 days for the group treated with chloramphenicol-oxyphenbutazone, 4.3 for those with chloramphenicol alone and 5 days for the group ampicillin-oxyphenbutazone; at the same time, blood cultures became negative at 4.4, 5.5 and 4.4 days respectively. Negativization of bone marrow cultures was not influenced by the addition of oxyphenbutazone. It is concluded that the influence of oxyphenbutazone in shortening the febrile period or in the negativization of blood cultures is not significant. It is considered that oxyphenbutazone is not an important therapeutic tool in this group of diseases.
