Pregnancy in Irish renal transplant recipients in the cyclosporine era.

BACKGROUND: The effect of renal transplantation on pregnancy in Irish women not receiving CyA has been reported previously. AIM: To examine all pregnancies occurring in Irish female renal transplant recipients since the introduction of CyA. METHODS: Using a community based approach, we identified 29 pregnancies in 19 women, aged between 16 and 45, mean age 30.3 years. RESULTS: These pregnancies ended in four miscarriages (13%), two intra-uterine deaths (6.9%) and 23 live births (79.3%). Of these live births, 73.9% were premature (< or = 36 weeks) and 65.2% were of low birth weight (< 2500 g). Admission to the neonatal intensive care was necessary in 61%, and two babies (8.7%) died in the neonatal period. Mean gestational age was 34 weeks, and mean birth weight was 2190 g. There was no change in graft function during pregnancy, with a small rise in serum creatinine post-partum (+9.64 mumol/L). The renal graft failed in three women (15.8%) by the end of the follow-up period. Compared with the precyclosporine era, the live birth rate was higher (79.3% versus 58%) with a trend towards lower birth weight and shorter gestation. CONCLUSION: Renal transplantation with CyA use is not a contraindication to pregnancy, but it is associated with increased risk, especially when the serum creatinine is > 175 mumol/L.

Skin and hair reflectance in women with red hair.

Skin and hair reflectance were measured with the Photovolt Spectrophotometer in 33 young women with red hair. Four skin sites were measured: forehead, check, inner arm and shoulder. A subsample of 15 red-headed women were tested before and at the end of the summer to test for tanning effects. The study was designed to test for relationships between hair and skin colour by reflectance spectrophotometry. As expected, subjects generally had very pale skin colour, pronounced freckling and very little tanning ability. Eumelanin (brown-black) pigment, as estimated by reflectance at 650 nm, was minimal at all skin and hair sites. Hair and inner arm reflectance values were highly correlated at short wavelengths, suggesting phaeomelanin as the source of the relationship. Estimates of tanning ability by use of the R/G ratio were very low in this sample of redheads.
