2.Ultrasound guided reduction of childhood intussusception
Journal of the Korean Radiological Society 1986;22(5):788-793
Following on from diagnosis using ultrasound, hydrostatic reduction using saline enema under ultrasoundguidance was tried in 20 cases of childhood intussusception. The conclusions were as follows: 1. Success rates ofsaline enema under ultrasound guidance during a frist-8 month period(P1) and a second 10 month period(P2) were55.6%(5/9) and 54.5%(6/11) respectively. Average succes rate was 55%(11/20). 2. During the periods of P1 and P2,no case was reduced by barium enema in 6 cases of failed reduction with saline enema. 3. During the period of P2, 5 cases of successful redution with saline enema were confirmed by clinical follow-up without barium enema. 4.During the periods of P1 and P2, 9 cases of failed reduction with saline enema were operated, resulting in 6 casesof segmental resection and 3 cases of manual reduction. 5. The obvious advantages of this method are: 1. Noradiation hazard. 2. No fear of barium peritonitis. 3. Detection of leading point. 6. With above results, thismethod could completely replace barium enema. And ultrasonography should be the initial study in the evaluation ofintussusception in children and then if necessary, saline enema under ultrasound guidance should be done.

Authors retrospectively analyzed the CT findings of cystic tumors of the mediastinum in surgically confirmed13 cases at Seoul National University Hospital during the recent 3 years from August 1980 to August 1983. Theresults are as follows: 1. Among 13 cases, bronchogenic cyst and cystic teratoma were 4 cases respectively,pericardial cyst were 2 cases, and thymic cyst and cystic hygroma was 1 case respectively. 2. CT No. of 4bronchogenic cysts was in the range of 12-112 HU, 3 cases among them had thick-walled capsules. CT No. of 4 cysticteratomas was in the range of

Horseshoe adrenal gland is a rare congenital abnormality associated with multiple congenital anomalies that may involve the cardiovascular, central nervous, and genitourinary systems. In this report, we describe the sonographic findings of horseshoe adrenal gland in a newborn with right isomerism a frequently associated cardiovascular anomaly.

BACKGROUND: The diagnosis of diseases caused by nontuberculous mycobacteria (NTM) is difficult, because NTM are prevalent in the environment such as soil and water, and because they have fastidious properties. In this study we investigated clinical isolates of NTM for their distribution pattern and accurate species identification. METHODS: We selected presumptive NTM isolates negative for probe hybridization for M. tuberculosis complex, cultured in a third referral hospital from 21 January 2003 to 20 January 2004. Ninety seven-isolates were identified to the species level by direct sequencing of fragments of 16S rRNA, hsp65 and rpoB genes. A total of 120 isolates were studied for the distribution analysis. RESULTS: Frequently identified NTM species were M. avium (30.8%), M. intracellulare (23.3%) and M. abscessus (18.3%). Others were M. gordonae, M. senegalense, M. fortuitum, M. peregrinum, M. kansasii, M. terrae complex, M. lentiflavum, M. chelonae, and M. szulgai. Three M. tuberculosis complex (2.5%) were also identified among the presumptive NTM isolates. The identification rate by sequencing of 16S rRNA, rpoB, and hsp65 were 65%, 82% and 87%, respectively. The hsp65 or rpoB gene was more efficient than 16S rRNA for the identification of NTM by sequencing. CONCLUSIONS: Some NTM are increasingly considered to be the causative organisms in clinical diseases. Thus, direct sequencing could be adapted to routine work of clinical laboratories for accurate identification of NTM to the species level.
