摘要:

It is the thesis of the author that the use of Ritodrine in the treatment of premature labor is potentially dangerous and possibly even lethal. Ritodrine is being overused in the attempt to control and delay premature labor. Only 25 to 50 per cent of patients complaining of premature labor pains actually proceed to true preterm labor. Because there is no definitive screening test to firmly establish the diagnosis of preterm labor, many women are treated unnecessarily with a drug that many obstetricians question as to its efficacy, safety, and cost. If it is used, it must be in a hospital with adequate facilities both in manpower and the ability to identify and treat the medical and obstetrical complications. Ritodrine is too potentially dangerous to be used as an attempt to “do something” it there are questionable indications.

摘要:

We conducted a detailed literature search for the rare combination of scleruderma and pregnancy. Ninety-four patients were reported, 14 of whom died during the course of the pregnancy, mainly due to secondary renal and cardiopulmonary involvement. Out of the 95 fetuses, 19 were lost. Thus, when complications arise, the option of prompt termination of the pregnancy should be considered.

摘要:

Documented reports of maternal malignancy metastatic to the placenta and fetus are rare. From 1866 until the present there have been 52 cases reported in the Western literature. We report a case of maternal large-cell carcinoma of the lung metastatic to the maternal brain and the placenta without fetal involvement.

摘要:

The purpose of this report is to describe a case of nonimmune hydrops fetalis that resulted from an unusual congenital heart defect, premature closure of the ductus arteriosus. In this fetus, the ductal closure was not associated with other heart defects such as tetralogy of Fallot or truncus arteriosus, nor was it related to maternal use of nonsteroidal antiinflammatory agents. Despite adequate digitalization of the mother, the fetus died of congestive heart failure at 29 weeks of gestation. Autopsy confirmed stricture of the ductus in association with enlargement of the foramen ovale and marked dilation of the right atrium and main pulmonary artery.

摘要:

The accurate estimation of gestational age is an essential part of pregnancy management, since the consequences of erroneous dating carry increased risks of perinatal morbidity and mortality. Ultrasonography offers a unique opportunity to objectively measure quantitative changes in growth increments of various fetal structures, as well as qualitative changes occurring near term which are indicative of fetal maturity. Therefore, dating through pregnancy is possible by the use of various parameters such as the crown-rump length, the trunk circumference, and the biparietal diameter in the first trimester; the biparietal diameter, the cerebellum, orbital distance, clavicular length, lengths of the long bones of the upper and lower extremities, and the foot length in the second and third trimesters; and the indices of maturity in the late third trimester such as colonic grading and epiphyseal ossification centers of the long bones of the upper and lower extremities. Using a combination of fetal biometry and maturity indices permit dating through pregnancy as a measure of growing up.
