The present study clarified the outcome of a targeted screening protocol for detecting congenital cytomegalovirus infection based on suggestive perinatal conditions. In addition, the positive rate was compared to those from the reported studies and the validity of the targeted screening criteria was discussed. A total of 2121 newborn infants were admitted to our hospital between October 2018 and October 2021. Cytomegalovirus DNA was examined by the isothermal nucleic acid amplification method for urine samples from newborns with any of the following: microcephaly, abnormal ultrasound findings in the brain and visceral organs, repeated failure in neonatal hearing screening, suspicious maternal cytomegalovirus infection during pregnancy, and other abnormal findings suggestive of congenital cytomegalovirus infection. Among 2121 newborns, 102 (4.8%) were subject to the urine cytomegalovirus DNA test based on the abovementioned criteria. Of them, three were cytomegalovirus DNA-positive. According to the protocol, the cytomegalovirus DNA-positive rates were 0.14% among the total enrollment of 2121 newborns and 2.9% (3/102) among the targeted newborns. This protocol may overlook congenital cytomegalovirus infection that is asymptomatic or exhibits inapparent clinical manifestations only at birth; however, it is feasible and helps lead to the diagnosis of congenital cytomegalovirus infection that may otherwise be overlooked.</p>","PeriodicalId":10626,"journal":{"name":"Congenital Anomalies","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2023-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9464714","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One such congenital anomaly is the microtia‐anotia spectrum, which results in deformities of the external ear, affecting the hearing capability of an individual. The collaboration and integration of electronics in human biology are exemplified by the development of a 3D printed cyborg bionic ear from the patient's own cells, which is implanted to ameliorate microtia and improve the patient's hearing capacity. Since the late nineteenth century, forensic scientists have explored the external ear, establishing the significance of ear biometrics in the identification process. Similarly, ear prints can also play an important role in identifying the felon of a crime. In this regard, we examine the structure and functionality of implanted ears.

We investigated the other congenital malformations and nutritional intake of neonates with cleft lip and/or palate and examined their relationships associated with cleft type and laterality. The participants included 126 infants under treatment with a presurgical naso-alveolar molding (PNAM) or a Hotz-type plate. The survey items were gender, cleft type and side, presence and nature of other congenital malformations, birth weight and nutritional method at age of the fifth day. The number of infants was 36 (28.6%) of cleft lip and alveolus, 82 (65.1%) of cleft lip and palate, and 8 (6.3%) of cleft palate only. Forty-three patients (34.1%) had other various congenital malformations. The nutritional method included oral intake in 78.6% (<i>n</i> = 99) of cases and tube feeding with/without oral intake in 21.4% (<i>n</i> = 27) of cases. The rate of tube feeding was higher for right-sided clefts than that for left-sided clefts. This observation was consistent with the fact that right-sided clefts were associated with more significant other congenital malformations than those on the left-side.

This is followed by further caudal growth with the reduction of the urogenital sinus epithelium. Finally, the vaginal epithelium of adult mice is entirely derived from the Müllerian duct epithelium. Here, we explored the mechanisms underlying mouse vaginal development via cell proliferation, apoptosis, and lineage analyses. We found that at the late embryonic stages, apoptosis occurred at the attachment site of bilateral Müllerian duct epithelia below the cervix, resulting in bilateral lumen traffic. The Müllerian duct epithelium was enclosed by the urogenital sinus epithelium at their boundary region on embryonic day (E) 16.5, whereas the Müllerian duct epithelium encased the urogenital sinus epithelium at postnatal day (P) 0 through lateral enlargement. Lateral Müllerian duct enlargement was accompanied by focal ERK activation within the curved epithelial tips and the specific localization of mitotic nuclei on the luminal side of the Müllerian duct epithelial layer at E17.5. Descent of the Müllerian duct epithelium and shortening of the urogenital sinus epithelium occurred rapidly after birth, accompanied by cell proliferation in the Müllerian duct epithelium and its peripheral mesenchymal tissues as well as intense apoptosis in the urogenital sinus epithelium around their boundary region.
