The radiologic and clinical findings of foreign bodies in the chest of children are well recognized. Foreign bodies in adults are infrequent, however, and the radiologic findings of these unusual circumstances have rarely been described. We classified various thoracic foreign bodies into three types according to their cause: Type I, Aspiration, Type II, Trauma or Accident; Type III, Iatrogenic. This pictorial essay will illustrate the radiologic findings and consequences of thoracic foreign bodies in adults, which have rarely been described in the radiologic literature. The clinical significance of thoracic foreign bodies will be also be discussed.

A total of 100 Vibrio spp. strains were examined for production of various extracellular enzyme and for plasmid content plasmid were subjected to digestion with restriction enzymes. Most of them produced extracellular enzyme more than one, especially V. parahaemolyticus and V. cholerae non-01 strains were showed production of various extracellular enzymes. About the 55% Vibrio spp. have the plasmid more than one, but a lot of Vibrio spp. (about 45%) did not possess any plasmid. Most of these plasmid various derivatives ranged from 2.4 kb-23 kb, especially two strains of V. mimicus and one strain of V. furnissii carried one high-molecular weight plasmid (molecular weight ranging between 70 kb-100 kb). Results of restriction analysis for plasmid of this three strains were by no means the rule. For detection of tdh and ctx gene, the virulence factor involved in the pathogenesis, we carried out the TDH, CT assay, PCR amplification, and hybridization. A total 11 strains were produced TDH, involved in 4 strains of V. parahaemolyticus and 1 strain of V. cholerae non-01 from clinical isolates and 6 strains of environmental isolates. Nine strains of 11 strains, involved in 4 strains of V. parahaemolyticus and 1 strain of V. cholerae non-01 from clinical isolates and 4 strains of V. parahaemolyticus from environmental isolates, could be successfully amplified in 400 bp by PCR, no amplification products were obtained from TDH-negative strains. The PCR results were consistent with DNA hybridization. In the experiments of ctx gene detection, in all, 3 strains of V. cholerae non-01 from clinical isolate and 1 strains of V. cholerae non-01 from environmental isolate were observed CT- positive. These CT-producing strains amplified in 302 bp by PCR for the detection of ctx gene. All CT-producing strains hybridized with digoxigenin-labeled DNA probe, while CT-negative strains did not hybridize. Also hybridization tests results for detection of ctx gene consistent with PCR.

Dubin-Johnson Syndrome is a form of benign, familial idiopathic jaundice presenting with chronic intermittentconjugated hyperbilirubinnmia and a melamin-like pigment has been found in the parenchymal liver cells. This disorder is rarely diagnosed in the neonatal period. We report a case of Dubin-Johnson syndrome presenting with neonatal cholestasis.

PURPOSE:The incidence of congenital adrenal hyperplasia(CAH) is 1/5,000- 1/20,000 births and thus the importance of the neonatal screening test is being emphasized. However, the reference value for the term and preterm infants has not yet been established and false positive values are frequent due the immature hypothalamic-adrenal axis of the preterm infants or the stress-induced adrenal dysfunction. Therefore, we analyzed the 17-hydroxyprogesterone(17-OHP) concentration in terms of gestational age, birth weight, and postnatal state to establish the reference range for the Korean term and preterm infants. METHODS:We analyzed the results of the CAH screening test retrospectively, which was performed on 737 neonates(624 fullterm neonates, 113 premature neonates) born between January 1998 through July 1998 in Inje University College of Medicine Sanggye Paik Hospital. Mean gestational age and birth weight of infants were 38.2+/-2.6 weeks and 3,116+/-674kg respectively. 17-OHP screening test was performed on 4.9+/-3.8days after birth by obtaining blood samples from the heelstick of neonates. 17-OHP concentration was measured by the ELISA kit(ICN Co.) and repeated the procedure if the result was higher than 35ng/ml. RESULTS: 1) 17-OHP concentration of the preterm infants was significantly higher than that of the fullterm infants(19.1+/-12.3ng/ml vs 11.7+/-7.8ng/ml, P=0.001). 17-OHP concentration was inversely proportional to gestational age. 2)17-OHP concentration was inversely proportional to birth weight(r=0.22, P>0.01). 17-OHP concentration according to birth weight was as follows.:below 1,500g was 26.7+/-11.7ng/ml, 1,500 to 2,000g was 18.0+/-13.9ng/ml, 2,001 to 2,500g was 17.9+/-10.5ng/ml, 2,501 to 3,000g was 12.1+/-7.9ng/ml, 3,001 to 3,500g was 11.5+/-8.1ng/ml, above 3,500g was 11.4+/-7.5ng/ml. There was a significant decline in the 17-OHP concentration as the birth weight increased. 3) 17-OHP concentration was gradually decreased as sampling date increased. 4) The gender of the infants did not influence the 17-OHP concentration(male 13.0+/-9.1 vs female 12.7+/-9.0). 5)17-OHP concentration were significantly higher in sick preterm infants than healthy preterm infants. 6)Six cases, whose 17-OHP concentration were greater than 35ng/ml, were all preterm and low birth weight infants. Reexamination after one week showed the value within normal range. No CAH cases were diagnosed in the study. CONCLUSION: 17-OHP concentration was inversely proportional to gestational age and birth weight. Therefore, reference ranges of 17-OHP concentration should be subdivided according to gestational age and birth weight. Further research about perinatal risk factors affecting the 17-OHP concentration will be required.
