Up until the early seventies fear of uterine rupture led to the widespread practice of 'once a section, always a section'. Nowadays, there is a consistent trend toward vaginal birth after a prior cesarean delivery, making early detection of uterine scar dehiscence at delivery important. However, the need for routine transcervical revision of the uterine(More)
During the past fifteen years the obstructive sleep apnea syndrome (OSAS) has become widely recognized as a quite common disorder with a wide range of serious clinical complications (1, 2, 3). This syndrome arises as a result of sleep related changes in upper airway muscle function and progressive narrowing of the oropharyngeal lumen. The resulting hypoxia(More)
The impact of placenta previa on intrauterine fetal growth was studied over a 10-year period, 1968-77. Fetal growth was assessed at the time of delivery by measurement of four parameters--birthweight, length, and head and chest circumferences. For 129 deliveries associated with placenta previa, these parameters were plotted against gestational age on Usher(More)
Intravenous leiomyomatosis is a rare benign neoplasm that commonly grows into the pelvic veins and the inferior vena cava and, rarely, the right side of the heart. We report the first case of intravenous leiomyomatosis with cardiac involvement in a pregnant woman. The treatment of choice is surgical resection in two steps.
Microalbuminuria is defined as urinary excretion of albumin that is persistently above normal, although below the sensitivity of conventional semiquantative test strips. Several studies have reported that Type 1 diabetic patients with microalbuminuria are apparently more likely to develop diabetic nephropathy eventually progressing to renal failure.(More)
Triphasic oral contraceptive (Logynon) induced a significant increase (36%) in the maximal binding capacity of platelet membranes for [3H]imipramine. The increase was achieved in the second Logynon cycle as compared to pretreatment and first Logynon cycle binding values. The pill contains a combination of ethinyl estradiol and levonorgestrel, and it is as(More)
Nonsteroidal anti-inflammatory drugs (NSAIDs) gained popularity in the late 1970s. Inhibition of prostaglandin synthesis with indomethacin has been reported to be effective for prevention of labor and for treatment for symptomatic polyhydramnios. Concern about its possible constrictive effect on the fetal ductus arteriosus has limited its use in pregnancy.(More)
In two neonates with partial Poland sequence, an infant with complete Poland sequence and his mother subclavian artery diameter and its flow velocity waveforms were determined by real-time echo-Doppler Duplex Scanner. These measurements were significantly lower than on the normal side in the same patient. Subclavian hypoplasia appears as a local vascular(More)
