INTRODUCTION The complete absence of the chiasm (chiasmal aplasia) is a rare clinical condition. Hypoplasia of the optic nerve and congenital nystagmus are almost invariably associated characteristics. Microphthalmos or anophthalmos are common features in chiasmal aplasia, while central nervous system abnormalities are less frequent. Esophageal atresia can be isolated or syndromic. In syndromic...

Management of esophageal atresia has merged from correction of the anomaly to the complete spectrum of management of esophageal atresia and all its sequelae. It is the purpose of this article to give an overview of all aspects involved in taking care of patients with esophageal atresia between January 2011 and June 2016, as well as the patients who were referred from other centers. Esophageal a...

Acute mastoiditis in the newborn is a very rare disease. Herein we report a case of a 28-day-old child with right aural atresia and ipsilateral mastoiditis requiring mastoidectomy. To our knowledge, this is the youngest case reported in the literature. Issues on diagnosis and management of mastoiditis in cases of aural atresia are further discussed. Based on our experience and on previous repor...

BACKGROUND The vertebral defect, anal atresia, cardiac defect, tracheoesophageal fistula/esophageal atresia, renal defect, and limb defect association and Mayer-Rokitansky-Küster-Hauser syndrome are rare conditions. We aimed to present two cases with the vertebral defect, anal atresia, cardiac defect, tracheoesophageal fistula/esophageal atresia, renal defect, and limb defect association and Ma...

More than 99% of ovarian follicles undergo atresia in mammals, but the mechanism of follicular atresia remains to be elucidated. In this study, we explored microRNA (miRNA) regulation of follicular atresia in porcine ovary. A miRNA expression profile was constructed for healthy, early atretic, and progressively atretic follicles, and the differentially expressed miRNAs were selected and analyze...

The morphology of the central pulmonary artery was studied by selective angiography in 21 previously unoperated patients (aged 11 days-21 years, median 4 years) with pulmonary atresia associated with various types of congenital heart disease. Angiographic findings were confirmed at operation in 10 patients. There was juxtaductal obstruction of the left pulmonary artery in two thirds of the pati...

Atresia ani is a congenital defect describes absence of a normal anal opening. It is fatal unless surgical correction is carried out to provide anal opening. In female, the rectum may break through vagina forming a rectovaginal fistula permitting defecation via the vulva. Surgical treatment of atresia ani is indicated to save the animal life and to improve body weight gain. Ten kids and eight l...

BACKGROUND AND PURPOSE Congenital causes of hearing loss in children commonly are encountered, and imaging aids in diagnosis as well as presurgical evaluation. Atresia of the oval window not associated with atresia of the external auditory canal (EAC) is a rare cause of congenital hearing loss in children. We present the clinical and imaging findings in children with isolated oval-window atresi...
