Segmental dilatation of the small intestine is a rare form of the congenital intestinal anomaly. Many other combined anomalies have been reported in, but the association with colonic duplication has not been reported in the literature. We report a case of segmental dilatation of the distal ileum associated with colonic duplication. The main clinical and pathogenic aspects are discussed, and the literatures are reviewed.

This is a case of tracheomalacia associated with esophageal atresia. An 11-month-old- male boy presented with a life-threatening apneic spell after correction of esophageal atresia (Gross type C). After complete exclusion of the other possible causes of the apneic spell, the presumptive diagnosis of tracheomalacia was made with fluoroscopy and 3-dimensional chest CT. The final diagnosis was made with rigid bronchoscopy under spontaneous respiration. The aortopexy was performed with intraoperative bronchoscopic examination. The postoperative period was unremarkably uneventful. The patient was discharged 9 days after the aortopexy and has remained well to date (5 months after the aortopexy).

In this paper, the optical axis alignment(OAA) of an infrared sensor(IRS) using a microwave sensor(MWS) was presented as a method of an axis alignment to minimize the problems that could be caused by the misalignment of the two sensors in the missile including the dual-mode sensor. The azimuth(AZ) and elevation(EL) angles of the two targets used for each sensor test were calculated by using the transformation equation and the test results of the MWS and IRS, and then the proposed OAA was verified by comparing the angles. Furthermore, the validity of the proposed OAA was demonstrated by confirming the abnormality of the OAA through the test results of the electro optical head(EOH) of the IRS which was equipped with a tilt on the missile fuselage.

The anomalous pancreaticobiliary duct union (APBDU) might cause the formation of choledochal cyst and malignancies of hepatopancreaticobiliary system. The purpose of this study is to make an experimental animal model of APBDU similar to that of human. One to two-month-old Mongrel dogs (n=12) were divided into two groups; the control group (n=2) had a sham operation performed, and in the experimental group (n=10) the end of distal ' common bile duct (CBD) was anastomosed to the side of the dorsal pancreatic duct making APBDD. Serum was obtained for chemical analysis on the 10th postoperative day. The dogs were sacrificed at the 5th week (n=3), the 6th week (n=3), the 7th week (n=2), the 8th week (n=2) and the 6th month (n=2) after the experimental surgery. With sacrifice, operative cholangiogram was taken, and bile juice was obtained for chemistry and bacterial culture. The en-bloc specimens of the hepatopancreaticobiliary system were removed for microscopic examination. Serum and bile juice amylase levels were elevated in the experimental group(n=10), but not in the control group(n=2). Operative cholangiograms of control group revealed no evidence of bile duct dilatation.. On the other hand, the bile duct in the experimental group was markedly dilated without any evidence of stenosis at the anastomosis site (n=10). Histologic examination of the hepatopancreaticobiliary system in the experimental group resembled the findings of choledochal cyst in human. The APBDU of this animal model can produce bile duct dilatation by pancreaticobiliary reflux. We think that this animal model can be potentially promising for the research about the APBDU associated hepatopancreaticobiliary diseases.

Percutaneous infraclavicular subclavian catheterization has been widely used for a total parenteral nutrition, hemodynamic monitoring and for venous access in difficult clinical situations. Many authors have claimed the infraclavicular cannulation of the subclavian vein in the tiniest infants can be performed with safety and ease, but there are always possibility of serious complications in this method. We present our experiences of peripheral venous cutdown with Broviac catheter. Author routinely introduced Broviac catheter into central vein via peripheral venous cutdown. There was no life threatening complications and no catheter related death. The complication rate was very low. The catheter related sepsis was documented in only two patient(4.7%). The average catheter longivity was 19.59 days. In view of the safety and low rate of complication, we think that peripheral venous cutdown with Broviac catheter should be the method of choice when central venous access is necessary in infants. The infraclavicular subclavian catheterization should be reserved in infants with few accessible peripheral vein.
