“…Errors in liquor examination during pregnancy occur (Hyslop and Whiley, 1960;Liley, 1963), while amniocentesis may have dangers both for the present (Mayer et al, 1961) or subsequent pregnancies. Zipursky et al (1963) established that bleeding from the foetus into the mother occurred in some cases.…”

The association of yellow amniotic fluid and hydrops foetalis has long been appreciated (Pickles, 1949) The tracings obtained show percentage absorption rather than optical density, so although the height of the peak is related to the quantity of pigment this relationship is logarithmic, not linear. Thus 10% absorption in the range zero to 10% absorption would give a peak in the tracing 10 times that produced by the same amount of pigment in the range 99-100% absorption. The effect of this is to minimize the degree of absorption at high levels of pigment and to exaggerate it at low levels. As most spectra produced less than 30% absorption and as we were really concerned to recognize low levels of bilirubin, we feel that this visual representation was satisfactory.

Haemolytic disease is a condition characterized by anaemia and jaundice, and the course may be more complicated in twins. We investigated the demographic and laboratory characteristics of twins with haemolytic disease of the newborn (HDN) and compared these characteristics between groups categorized according to multiple birth status (twins vs. singletons) and conception method (assisted reproductive technology (ART) vs. spontaneous conception). Fifty-five twins with HDN and 253 singletons with HDN who were born during the same period (controls) were included in the study, and we performed comparisons between them. The results showed that twin infants were more likely to be premature, have a low birth weight and be conceived via ART than their singleton counterparts. Moreover, a variety of comorbidities were identified more frequently in twins with HDN than singletons with HDN. The minimum haemoglobin and the initial and maximum total bilirubin, albumin and complement 3 (C3) were all significantly lower in twins than in singletons; however, these two groups were not found to differ significantly by direct antiglobulin test (DAT) status. Twins conceived via ART had a lower minimum haemoglobin and initial bilirubin than twins conceived spontaneously. The results of this study suggested that neonatal comorbidities were more common in twins with HDN than singletons with HDN; however, DAT positivity did not appear to play a major role in the higher rates of comorbidities and lower concentration of haemoglobin observed in twins. Among twins with HDN, conception via ART may serve as a risk factor for increased disease severity.
