No association between maternal psychological symptoms and infant outcome after pregnancy complicated by early-onset hypertensive disorders.

AIM: The aim of this work was to study the effect of maternal psychological symptoms on infant development 1 year after early-onset hypertensive disorders of pregnancy. METHODS: All mothers were enrolled in the Pre-eclampsia, Eclampsia TRial Amsterdam. Mothers were asked to complete the 90-item Symptom Check List (SCL-90) at the corrected ages of their infants of 0, 3 and 12 months. The total sum score of these three checklists was calculated. Infants were examined at the corrected age of 12 months using the Bayley Scales of Infant Development (Mental Developmental Index [MDI] and Psychomotor Developmental Index [PDI] subscales). The Bayley scores were compared between infants of mothers with SCL-90 sum scores in the highest 25% and lowest 75%. RESULTS: For 141 mother-infant pairs (80%) all three SCL-90 checklists and Bayley scores were available. Mean gestational age was 32 weeks and 90% of the infants were growth restricted. The mean MDI was 87 in the highest 25% and 89 in the lowest 75% group. This was 79 versus 80 for the PDI. CONCLUSION: In this population of high-risk growth-restricted infants born after a pregnancy complicated by early-onset hypertensive disorders, there is no additional impact of negative maternal psychological symptoms on infant development after 1 year.

Cutaneous perfusion of the human lactating breast: a pilot study with laser Doppler perfusion monitoring.

OBJECTIVE: Knowledge on the hemodynamics of the human lactating breast contributes to our understanding of lactation physiology, as well as the development and management of breastfeeding problems. The objective of this pilot study was to investigate whether laser Doppler perfusion monitoring (LDPM) can be employed to measure physiological changes in mammary cutaneous perfusion during milk extraction. APPROACH: We evaluated mammary cutaneous perfusion with LDPM in nine lactating women during milk extraction in both the ipsilateral ('milk extracting') and contralateral ('passive') breast. Fourier domain filtering of the LDPM signal was applied to correct for the influence of the periodic tissue movement caused by the breast pump. MAIN RESULTS: Cutaneous perfusion increased temporary during 23.7 ± 18.9 s by 18%-74% for all women who sensed their milk ejection reflex (n = 6) in both the ipsilateral and contralateral breast. For those women who did not sense a milk ejection reflex (n = 3), the changes in cutaneous perfusion were less outspoken (maximally 26%). SIGNIFICANCE: This pilot study provides new insights into mammary hemodynamics and demonstrates that LDPM is a promising method for the further investigation of physiological changes in mammary cutaneous perfusion during milk ejection. Objective feedback on the occurrence and progression of milk ejection can support lactation research in general, maternal breastfeeding confidence, and may be an early indicator for the development of breastfeeding problems.

Two Siblings With a CDKL5 Mutation: Genotype and Phenotype Evaluation.

This is the second report of a family with a recurrence of a CDKL5 mutation (c. 283-3_290del) in 2 sisters. Both parents tested negative for the mutation in all tissues, but germline mosaicism is likely. Clinically CDKL5 patients resemble those with Rett syndrome, caused by a MECP2 mutation, who experience a regression, after an initial normal development. Even though both siblings showed a typical CDKL5 phenotype, their presentation is different. From birth, the oldest daughter had a severe developmental delay, feeding problems, and hypotonia and experienced daily refractory seizures. The youngest daughter appeared to be normal until age 3 months. At that age seizures started, deterioration and regression became evident, and an epileptic encephalopathy developed. This report of familial recurrence, with suspected germline mosaicism in a healthy parent, has important consequences for genetic counseling. Although it is not possible to predict an exact recurrence risk, it is likely to be increased.
