Introduction  The main histological features of the nasal mucosa in choanal atresia are distorted cilia, marked increase of mucous submucosal glands associated with marked reduction of goblet cell density, and lymphocytic cellular infiltration. Objective  To study the nasal mucosal changes in cases of choanal atresia after successful repair compared with pre-repair mucosal histological features...

Atresia anal é um defeito congênito comum em animais que frequentemente acomete bezerros e leitões. Normalmente há pouco mais pele subcutis permanecendo sem perfuração, sendo possível realização de abertura cirúrgica satisfatória, desde o esfíncter muscular reto estejam desenvolvidos. Este relato caso teve como objetivo descrever protocolo tratamento cirúrgico atresia bezerro. A pesquisa examin...

OBJECTIVE To provide an updated review on extrahepatic biliary atresia, focusing mainly on its etiopathogenesis, diagnosis, treatment and prognosis. SOURCES MEDLINE and PubMed databases were searched using the following keywords: biliary atresia, etiopathogenesis, diagnosis, treatment, prognosis, children. SUMMARY OF THE FINDINGS Extrahepatic biliary atresia is the main indication for liver...

PURPOSE The aim of this study was to evaluate the usefulness of magnetic resonance cholangiography (MRC) for the diagnosis of biliary atresia in infantile cholestatic jaundice. METHODS Forty-seven consecutive infants with cholestatic jaundice underwent single-shot MRC. The diagnosis of biliary atresia was made by MRC based on the nonvisualization of extrahepatic bile ducts and excluded on the...

We investigated the expression of transforming growth factor-β1 (TGF-β1) and connective tissue growth factor (CTGF) in the liver tissue of infants with congenital biliary atresia and neonatal hepatitis, as well as the relationship between the expression of the two factors and liver fibrosis. Thirty-six infants who met the cholestasis criteria were classified into congenital biliary atresia and ...

Fourteen patients with double inlet left ventricle and nine patients with tricuspid atresia had biplane left ventricular angiography with simultaneous measurement of left ventricular pressure by micromanometer. Age distribution, haemodynamic function, and previous palliative operation were similar in the two groups. Left ventricular volumes were calculated frame by frame throughout the cardiac ...

In muscular pulmonary atresia, major aortopulmonary collateral arteries are characteristic of pulmonary atresia with ventricular septal defect and are rarely seen in pulmonary atresia with intact ventricular septum. Two unusual cases of muscular pulmonary atresia are reported, one with an intact septum and one with a perimembranous ventricular septal defect, closed in utero by aneurysmal tricus...

Congenital diaphragmatic hernia is known to be associated with esophageal atresia, which is a rare association. We report a rare occurrence of congenital diaphragmatic hernia and lower esophageal atresia.

Throughout ovarian development and function in mammals, a highly orchestrated, periodic process known as follicular atresia occurs that destroys and eliminates follicles and oocytes from the ovary. Follicular atresia is pervasive. In humans, it is estimated to account for 99.9% of the loss of oocytes from development of the fetal ovary until reproductive senescence (Baker, 1963; Faddy et al., 1...

Oesophageal atresia and/or tracheo-oesophageal fistula are common malformations occurring in approximately 1 in 3500 births. In around half of cases (syndromic oesophageal atresia), there are other associated anomalies, with cardiac malformations being the most common. These may occur as part of the VACTERL association (OMIM 192350). In the remainder of cases, oesophageal atresia/tracheo-oesoph...
