METHODS This report describes a population-based study of all births at the Obstetrics and Gynecology Hospital of Fudan University in Shanghai, China from January 2008 to December 2014. A logistic regression analysis was used to identify the parameters that are independently associated with birth defects. RESULTS A total of 82814 births, including 824 cases of birth defects, were recorded. The rate of birth defects was 0.995 per 100 births. In the multivariable regression analysis, neonatal birth defects were likely to be associated with higher gravidity [odds ratio(OR), 1.099, 95%CI: 1.024-1.178], premature birth(OR = 1.905, 95%CI: 1.501-2.418), low birth weight(OR = 3.844, 95%CI: 3.004-4.919), twin births or higher order multiple pregnancies(OR = 1.477, 95%CI: 1.107-1.969), cesarean delivery(OR = 1.184, 95%CI: 1.016-1.380) and registration as part of a migrant population(OR = 1.380, 95%CI: 1.167-1.632). Female infants were less likely to have birth defects than male infants(OR = 0.710, 95%CI: 0.616-0.818). CONCLUSION Higher gravidity, premature birth, lower birth weight,twin births or higher order multiple pregnancies, and registration as part of a migrant population are independent predictors of birth defects.展开更多

A twenty-eight-year-old female has presented to emergency unit with the complaint of gastrointestinal hemorrhage. This patient, who had been monitored in the gastroenterology clinic more than 10 times in the past 8 years, noted a repetitive hemorrhage during her previous pregnancy in her history. The examination of the patient revealed the following signs and symptoms： atrophy in the epithelium of the retina pigment; typical angioid streaks and peau d＇orange finding in the fundus; thinning of the retinal nerve fiber in OCT （optic coherence tomography）; bilateral and reticular papillary lesions with yellowish- color in the neck region （plucked chicken appearance）; presence of bleeding loci in fundus, and nephrocalcinosis in kidneys. In light of these symptoms, the patient was diagnosed with pseudoxantoma elasticum. Skin biopsy confirmed the pseudoxantoma elasticum diagnose. PXE is an uncommon, hereditary disease. Early diagnosis of pseudoxantoma elasticum cases, is important for minimalizing systemic complications and informing the other family members through genetic counseling.展开更多
