The presence of autoantibodies in the fetus has previously been investigated in the offspring of mothers with autoimmune diseases, but not in the offspring of healthy pregnant women. Employing the ELISA method, we examine four SLE-associated auto-antibodies (anti-dsDNA, anti-ssDNA, anti-poly(I), and anti-cardiolipin) in sera obtained from 196 healthy pregnant women and their offspring. All detected autoantibodies in maternal and blood cord sera were of the IgM isotype. Thirty-four maternal sera (17.3%) were positive for one or more tested autoantibodies: 16 (8.1%) for one autoantibody alone, 17 (8.6%) for two autoantibodies, and one (0.5%) for three autoantibodies; 1.5%, 5.6%, 9.6%, and 10.2% of the maternal sera were positive for autoantibodies against dsDNA, ssDNA, poly(I), and cardiolipin, respectively. In only one blood cord serum sample was an autoantibody (IgM anti-ssDNA) detected. This infant was born to a healthy seronegative mother. The finding that all offspring of IgM seropositive mothers are IgM seronegative is not surprising since maternal IgM autoantibodies do not cross the placenta. The finding of an IgM seropositive infant born to an IgM seronegative mother may indicate that the fetus is capable of self-production of autoantibodies.
It was the aim of this study to evaluate critically the value of history in patients complaining of urinary stress incontinence. Diagnosis was established mainly by radiologic and cystomanometric assessment. History included 21 symptoms subdivided into various items. Only 3 symptoms were proven significant in distinguishing between various diagnostic groups. Assessment of stress incontinence should be regarded as incomplete without other means of evaluation in addition to history.
An unusual case of a 31 year-old Bedouin women, with secondary infertility of 13 years' duration who conceived twice spontaneously after removal of a hydatic cyst from her frontal lobe is reported. The reproductive function was restored probably by releasing the hypothalamic-pituitary axis from the pressure exerted by the cyst.
To predict the development of respiratory distress syndrome (RDS), the authors determined the fluorescent polarization values on gastric aspirates obtained from 67 premature infants within 30 minutes of birth. In 29 cases these results were also compared with the fluorescent polarization values measured on the corresponding amniotic fluid samples. Measurements for microviscosity were made by fetal lung maturity analyzer. Among 15 of 67 premature infants who developed RDS, the fluorescent value measured on gastric aspirates in all 15 infants was greater than 0.320. The fluorescent polarization values were less than 0.320 in all 52 infants in whom RDS did not develop, a predictability of 100%. Direct comparison found fluorescent polarization values measured on gastric aspirates to be somewhat lower than the corresponding amniotic fluid fluorescent polarization values. The results indicate that gastric aspirate obtained within 30 minutes of birth contains swallowed amniotic fluid. In cases where amniotic fluid samples were not available for surfactant evaluation prenatally, the determination of fluorescent polarization values on the newborn's gastric aspirate may accurately predict the development of RDS. The use of the fetal lung maturity analyzer microviscosimeter provides a simple, reliable, and rapid (45 minutes) method for assessment of surfactant in premature infants.
