Neonatal asymmetric crying facies syndrome：a case report and literature review

Abstract

Objective To determine the clinical characteristics of neonatal asymmetric crying facies and to review the latest progress in clinical research of this condition. Methods Clinical and laboratory data of a case of neonatal asymmetric crying facies syndrome admitted to Peking Union Medical College Hospital in March, 2013 was reported. Clinical charateristics, chromosome abnormalities, treatment and prognosis of neonatal asymmetric crying facies reported in China were analyzed, and pertinent literatures in China Knowledge Resource Integrated Database and CQVIP Database were reviewed. Results Eighteen Chinese reports on this syndrome were retrieved and 48 patients, 31 males and 17 females including our patient, were analyzed. Twelve patients had neonatal asymmetric crying facies and 36 patients had neonatal asymmetric crying facies syndrome. Anomalies in these children included malformations of the heart （26 cases, 72.2%）, ear （11 cases, 30.6%）, gastrointestinal tract （4 cases, 11.1%）, cleft palate （2 cases, 5.6%） and fingers （2 cases, 5.6%）. Standard chromosome analysis in three studies was normal. In one case, chromosome 22q11.2 microdeletion was not found using flucrescence in situ hyloridization analysis. There were few studies with long-term follow-up in China. Conclusions Neonatal asymmetric crying facies are complicated with a high rate of other malformations. Identification of associated malformations and close follow-up are required, and intervention should be carried out earlier so as to ensure a good outcome.
