Cervical esophageal duplication cysts are uncommon congenital malformations, and those with air-fluid level are rarely reported. We describe here a case of cervicothoracic esophageal duplication cyst manifesting air-fluid level on Computed Tomography (CT) in a 6-month-old girl. The preoperative diagnosis was suspected as esophageal duplication or abscess. The postoperative pathological diagnosi...

Müllerian anomalies are very common, and a frequent cause of infertility. The most used classification system until now, proposed by the American Society for Reproductive Medicine in 1988, categorizes comprehensively uterine anomalies but fails to classify defects of the cervix or vagina. This is based on a developmental theory that postulates that müllerian duct fusion is unidirectional, begin...

Esophageal duplication cyst is a rare congenital anomaly resulting from a foregut budding error during the fourth to sixth week of embryonic development. Cervical esophageal duplication cysts are very rare and may cause respiratory distress in infancy. A full-term newborn girl who was born by normal delivery was transferred to our hospital because of swelling of the right anterior neck since bi...

purpose: to report a case who had optic disc duplication, a rare congenital disorder characterized by two well-defined discs in one eye. case report: a 19 months-old child presented with unilateral epiphora in the right eye since birthday. the right eye was smaller than the left eye and mild ptosis was apparent. nasolacrimal duct probing was performed under general anesthesia. the examination r...

A case of incomplete duplication of the esophagus diagnosed in a 20-month-old girl with an esophageal perforation is presented. X-ray films of the chest showed pneumomediastinum and subcutaneous emphysema. A water soluble contrast esophagogram revealed a contrast leakage from the cervical esophagus to the thoracic inlet. The endoscopic findings are described. Complete resection of the esophagea...

The notion that gene duplications generating new genes and functions is commonly accepted in evolutionary biology. However, this assumption is more speculative from theory rather than well proven in genome-wide studies. Here, we generated an atlas of the rate of copy number changes (CNCs) in all the gene families of ten animal genomes. We grouped the gene families with similar CNC dynamics into...

Case Description- A three month Holstein female calf with a supernumerary limb in the caudal cervical region was delivered to a private veterinary clinic in Kashmar.Clinical Findings- Clinical and radiographical examinations revealed a vestigial scapula, distally bifurcated humerus, two underdeveloped ulnae, two ossification centers for radius and more or less complete duplication of manus in t...
