Long-term treatment of hypertension with methyldopa. I. Study objectives and design.

In this retrospective study, a group of 435 patients provided meaningful analyses of blood pressure and dosage data for treatment periods of up to 4.5 years. The protocol, study objectives, and pretreatment demographic characteristics of the group are summarized in this report, which is the first in a series in this issue describing the results of this survey.

Anti-inflammatory drug treatment of Crohn's disease: a prospective evaluation of 100 consecutively treated patients.

We have analyzed the results of anti-inflammatory drug treatment of 100 consecutively treated patients with Crohn's disease. The disease affected the colon in 12 patients, small bowel in 36, and both colon and small intestine in 52. Thirty-two patients had had a prior resection of Crohn's disease. According to an adaptive design, patients were treated with sulfasalazine if able to take oral drugs; with steroids if unable to take, or unresponsive to, sulfasalazine; and with added azathioprine if unresponsive to sulfasalazine and steroids and unsuitable for surgery. Drug regimens included sulfasalazine alone in 39 patients, steroids alone in seven patients, both sulfasalazine and steroids in 43 patients, and added azathioprine in 11 patients. All patients completed at least 1 year, or were regarded as treatment failures after 3 months of drug treatment. We analyzed clinical and radiographic responses. Significant improvement occurred in all categories of patients: complete or partial clinical remission was observed in 79%, and complete or partial radiographic regression was observed in 55%; 30% of patients were not reexamined radiographically and the remainder showed no improvement. Our study suggests that properly selected anti-inflammatory drug therapy has definite benefits and is indicated for patients with Crohn's disease.

Lipoprotein X and alkaline phosphatase as indicators of cholestasis.

Lipoprotein X is considered to be an indicator of cholestasis, but its clinical usefulness is unclear owing to different methods of measurement in use and varying definitions of cholestasis. We investigated the reliability of the qualitative determination of lipoprotein X in predicting cholestasis, defined here as the presence of stainable bile in tissue sections. Liver tissue and serum were collected from 42 patients. Patients were divided into those who did and those who did not have stainable bile in tissue sections. Lipoprotein X was demonstrated by electrophoresis and polyanion precipitation. Lipoprotein X in serum correlated with the presence of stainable bile (p = 0.0006). A normal range of alkaline phosphatase values correlated with the absence (p = 0.04), but elevated values did not correlate with the presence of stainable bile. In patients known to have elevated alkaline phosphatase, the presence of lipoprotein X still correlated with the presence of bile (p = 0.008). We conclude that lipoprotein X is a reliable indicator of cholestasis and that it is more useful than alkaline phosphatase in this application.

Early intrauterine development: I. The rate of growth of Caucasian embryos and fetuses between the 6th and 20th weeks of gestation.

Liberalization of abortion laws in various countries and states of Europe and America has offered an opportunity for the study of the correlations between menstrual age and the rate of bodily development of human embryos and fetuses. In several institutions where local bylaws mandated the consent of the patients requesting therapeutic abortion to pathological investigation of the products of conception, various parameters of growth were measured systematically. These included crown-rump and foot lengths and body weight. The analysis of the data indicated that in the embryosic stages of development the rate of growth is substantially slower than it had been assumed previously. In the more advanced fetal stages of development the findings supported the validity of the long-established standard of Streeter. Since the current study has been based on apparently normal gestations of healthy women, whereas earlier data had rested, to a great extent, on spontaneously aborted and extopic embryon and fetuses, it seems evident that pathological specimens are not suitable for the purpose of establishing reliable standards of normal intrauterine growth rate. The present data support the suggestion, based on various experimental and clinical observations, that pathological gestations often result from abnormal ovulations that occur at times other than the mid-cycle and that such conceptions are frequently followed by a bleeding episode that simulates menstruation. It is likely that the inclusion of a high number of such cases biased the results of earlier investigations concerning embryonic growth rate on account of the frequent incidence of erroneous menstrual histories. The material available did not permit the extension of the investigation beyond the 20th week of gestation. It appears, however, that the average growth rate in the mid-trimester may be slower than the data adopted by the American Academy of Pediatrics would indicate. The possible causes of some phenomena observed in the course of the investigation, such as unexplained scatter of growth-rate patterns at all developmental stages and discrepancies among various literary data, have been discussed in some detail. While a tentative attempt has been made to correlate the investigated parameters of fetal growth with biparietal diameters of the head, a measurement accessible to direct assessment by sonography during pregnancy, the necessity of improving these standards through a prospective study has been emphasized.
