Abstract
The aim of this study was to evaluate the maternal and foetal factors affect higher cell-free DNA (cfDNA) levels and to investigate a possible relationship between high cfDNA levels and adverse perinatal outcomes. From a total of 4594 women who underwent non-invasive prenatal testing from January 2016 to March 2018 in our hospital, 112 women had high levels of cfDNA, which was not appropriate for testing. Maternal characteristics and perinatal outcomes were compared between patients with high levels of cfDNA and normal levels of cfDNA. Patients with high levels of cfDNA had greater risks than patients with normal cfDNA levels of pregnancy complications but no statistically significant difference was found. Patients with high cfDNA levels had higher foetal death rates with a statistically significant difference (9.8% versus 1.8%, p = .024). An increase in foetal death could be expected in patients with increased cfDNA levels; therefore, these patients should be carefully followed up during pregnancy.IMPACT STATEMENTWhat's already known about this topic? Most studies about cfDNA levels are focussed on the foetal fraction. There are new arguments about maternal health and cfDNA. It is known that autoimmune diseases as systemic lupus erythematosus (SLE) and maternal obesity increase cell turnover. There are also clinical studies suggesting a relationship between low molecular weight heparin therapy and the amount of cfDNA.What do the results of this study add? This is the first study evaluating the maternal and foetal biological factors affecting cfDNA concentrations and investigating the possible relationship between high cfDNA levels and adverse perinatal outcomes in patients with high levels of cfDNA compared to patients with normal levels of cfDNA. In the present study, it was found that an increase in foetal death could be expected in patients with higher cfDNA levels.What are the implications of these findings for clinical practice and/or further research? If potential effects and underlying causes of increased cfDNA could be explained, cfDNA might be used as a biomarker for adverse perinatal outcomes.

Abstract
Chromosomal microarray (CMA) analysis for discovery of copy number variants (CNVs) is now recommended as a first-line diagnostic tool in patients with unexplained developmental delay/intellectual disability (DD/ID) and autism spectrum disorders. In this study, we present the results of CMA analysis in patients with DD/ID. Of 210 patients, pathogenic CNVs were detected in 26 (12%) and variants of uncertain clinical significance in 36 (17%) children. The diagnosis of well-recognized genetic syndromes was achieved in 12 patients. CMA analysis revealed pathogenic de novo CNVs, such as 11p13 duplication with new clinical features. Our results support the utility of CMA as a routine diagnostic test for unexplained DD/ID.

Abstract
A variety of diseases can cause vesicular or pustular eruptions in newborns. A thorough clinical history and physical exam provide important clues for differential diagnosis. Goltz syndrome, also known as focal dermal hypoplasia, is a rare genodermatosis and generally diagnosed by the presence of the characteristic skin lesions. We present an infant with aplasia cutis, atrophic skin lesions, syndactyly and eye abnormalities who was diagnosed with Goltz syndrome soon after birth. Goltz syndrome should be considered in differential diagnosis of hypoplastic or aplastic skin lesions in neonates in the presence of skeletal or ophthalmic anomalies.

Abstract
Malformations of the lower limbs are rare and heterogeneous anomalies. Some congenital anomalies involving face, gastrointestinal system, skeletal system, urogenital system, heart, lung and diaphragma associated with lower limb malformations have been described in the literature. Here, we report a case of left proximal femoral focal deficiency (PFFD) together with fibular aplasia associated with left undescended testis and hypospadias. The putative embryologic mechanisms of lower limb defects and their possible association with lower urogenital tract malformations are also discussed.
