Clin Exp Pediatr. 2000;43(2):283-287.   Published online February 15, 2000
Intrahepatic portosystemic venous shunt(IPVS) is an uncommon pathologic condition which occurs mostly in adult patients with portal hypertension and cirrhosis of the liver with only scattered reports are on children. However, asymptomatic IPVS have been detected in an increasing number of patients with recent advances in imaging techniques, such as sonography, CT, MR imaging, and color Doppler sonography. The cause...

Yeon Soo Lim, Jae Kook Cha, Kon Hee Lee, Kwan Seop Le
Clin Exp Pediatr. 1999;42(1):138-142.   Published online January 15, 1999
Acute focal bacterial nephritis(AFBN) is an unusual form of localized renal infection, which has various imaging findings and should be distinguished from abscess or other renal masses. Clinical symptoms are similar to other urinary tract infections but the diagnosis needs a CT or sonographic confirmation. Treatment, which is nonoperative, consists of intensive antibiotic therapy. We report three cases of AFBN...

Clin Exp Pediatr. 1996;39(4):497-502.   Published online April 15, 1996
Purpose : Accurate clinical diagnosis of acute appendicitis is more difficult in children since they may not be able to communicate their complaints adequately, and findings on physical examination may be nonspecific.The uncertainty in diagnosis may lead to a delay of surgery or to unnecessary laparotomy. Prompt diagnosis is important due to their complications such as perforation, abscess formation, and...

Thirty consecutive partient seen in a pediatric out patient and emergency department, in whom the diagnosis of intussusception was considered, had an ultrasound examination of the abdomen before the barium enema. The peak age was 5~12 month(range 4~34 month). Intussusception was detected by ultrasonography in all 25 cases proved by barium enema(sensitivity 100%).

Clin Exp Pediatr. 1986;29(12):1377-1381.   Published online December 31, 1986
Since the initiation of routine vitamin K prophylaxis in the newborn, the incidence of hemorrhagic disease of the newborn has been dramatically decreased. We report here a case of intracranial hemorrhage due to vitamin K deficiency in a 2-month-old which was diagnosed with cranial ultrasonography. With advent of cranial ultrasonography which is portable, relatively inexpensive and noninvasive, the intracranial hemorrhage is easily confirmed especially as...
