ABSTRACT
Objective To investigate the imaging manifestations of congenital intestinal malrotation. Methods The clinical data of 92 infants with congenital intestinal malrotation admitted from January 1993 to December 2012 were studied retrospectively. All the 92 cases enrolled in this study were diagnosed based on imaging examinations and confirmed surgically. The imaging features of four examinations including plain abdominal radiography, upper gastrointestinal radiography, lower gastrointestinal angiography and ultrasound examination were analyzed. Results The percentage of the infants who presented with the initial clinical symptoms of vomit, blood stool and abdominal dilatation was 87.0%(80/92), 3.3%(3/92) and 1.1%(1/92), respectively, and eight cases [8.7%(8/92)] received prenatal ultrasound, which showed intestinal malrotation. Clinical examination showed no abdominal abnormalities in 68 (73.9%) cases. Seventy-seven cases underwent plain abdominal radiography, revealing intestinal obstruction in 31 cases. Thirty-six cases underwent upper gastrointestinal radiography, which revealed malrotation in 14 cases, and duodenal complete/incomplete obstruction or stenosis in 19 cases. Twenty-two cases underwent lower gastrointestinal angiography, and all of them were diagnosed as malrotation. Seventy-nine cases were examined with abdominal ultrasonography, and 58 cases were diagnosed as malrotation. Conclusions Rational selection of imaging examinations can improve the preoperative diagnosis. When congenital intestinal malrotation is suspected, abdominal ultrasound should be done as the first optional examination. At the same time, plain abdominal radiography should be selected accordingly. When intestinal malrotation with or without midgut volvulus is suggested, surgery should be performed as early as possible. When the diagnosis is not clear, upper or lower gastrointestinal radiography should be done.
ABSTRACT
Objective To study the effects of perinatal and postnatal cytomegalovirus(CMV) infection on infantile physical development and nerves mental growth. Methods We observed forty-eight cases of perinatal and postnatal CMV infection infants and twenty-two cases of non-CMV infected infants. We compared the physical development between two groups at birth ,3 months and 1 year of age, and evaluated development quotient (DQ) at 1 year of age. Results There were no significant differences of baby length,weight, head circumference between two groups at birth and 3 months (P > 0.05). The averages of baby length,weight,and head circumference were all in the normal range,which showed no significant differences between two groups(P > 0. 05). There were no significant differences in DQ of rough movement,accurate movement, adaptability, language and sociality ability between two groups at 1 year of age (P > 0.05). The averages of total DQ were in the normal range, which showed no significant difference between two groups as well (P > 0. 05). According to the evaluation hierarchies, DQ values of two groups were mostly in normal level range, and there also was no significant difference(x2 = 1. 026, P > 0. 05). Conclusion The perinatal and postnatal cytomegalovirus(CMV) infection has no significant adverse effects on infantile physical development and neuro-psychological development.
ABSTRACT
Objective To study the clinical characteristics of necrotizing enterocolitis(NEC) in premature neonates. Methods Twenty eight premature and 35 full term neonates with NEC in our hospital from 1994 to 2003 were enrolled in this retrospective study. The clinical manifestation, X ray and laboratory results were analyzed. Results The presentations of premature group were more severe than that of the full term group,such as poor perfusion (54% vs 26%, P
