ABSTRACT
Purpose@#The purpose of this study was to identify factors influencing the Radiation Protection(RP) behaviors of endoscopy nurses during endoscopic interventional radiology. @*Methods@#A total of 188 endoscopy nurses working at 30 tertiary or general hospitals participated in this questionnaire-based study. The questionnaire included items on general and job related characteristics, RP knowledge, RP attitude, RP behavior, self-efficacy, and safety climate. Data were collected through online surveys from March 22 to April 10, 2019. @*Results@#Multivariate analysis revealed that RP attitude (β=.65, p<.001), safety climate (β=.12, p=.035), self-efficacy (β=.14,p=.009), and existence of RP protocols (β=.11,p=.038) were significant predictors of better RP behavior. @*Conclusion@#The findings showed that the RP behavior of endoscopy nurses was at high levels and the continuing education for endoscopy nurses and development of a radiation safety management education program were important to improve RP behavior.

ABSTRACT
Congenital complete atrioventricular heart block(CCAVB) is a rare disease of the newborn that carries significant mortality and has a heterogenous etiology. It may occur as a result of the presence of maternal autoantibodies that are transferred to the fetus and affect the fetal heart or be associated with a congenital structural abnormality of the heart. Infants with CCAVB are at risk of diminished cardiac output and the subsequent development of congestive heart failure. We report two cases of CCAVB in newborns treated with pacemaker implantation after birth. The first case revealed CCAVB with patent ductus arteriosus and anti- Ro(SS-A) antibody in both of the mother and the newborn. The second case was accompanied with mitral regurgitation and tricuspid regurgitation, but anti-Ro(SS-A) antibody was absent in both of the mother and the newborn. Pacemaker implantation was performed for both cases and the result was favorable. We concluded that our experience supports that the pacemaker implantation in the newborn is feasible and beneficial in the treatment of CCAVB.

PURPOSE: Congenital chloride diarrhea(CLD) is an autosomal recessive disease characterized by life-long watery diarrhea of prenatal onset with high fecal Cl concentration. Recent studies have revealed that the protein product of the down-regulated in adenoma(DRA) gene is an intestinal anion transporter molecule and causes CLD when mutatec4: We investigated the clinical characteristics of CLD in Korean infants in order to increase awareness of this disease, which might be simply overlooked as chronic diarrhea. METHODS: Medical records of 5 infants admitted to the pediatric departments of Eulji Medical Center and Seoul National 1Jniversity Children's Hospital from April 1988 to January 1998 with the diagnosis of CLD were retrospectively reviewed. The criteria for inclusion in the study were based on a typical clinical picture and high fecal Cl RESULTS: There were 4 boys and 1 girl, 2 of them were siblings with no consanguinity in their parents. Their ages ranged from birth to l4 months. The mean gestational age was 36 weeks and the mean birth weight was 2.99kg. In all patients abdominal distension, jaundice and watery diarrhea with a history of maternal polyhydramnios were found, lack of meconium passage was also documented and fecal Cl levels were greater than 90mmol/L. Three patients who were diagnosed beyond neonatal period had retarded growth and delayed development and presented hypochloremic hypokalernic dehydration. Two of thern were in a state of metabolic alkalosis. CONCLUSION: CLD should be considered in infants presenting with intractable watery diarrhea, abdominal distension, prematurity and history of polyhydramnios. Full replacement of the fecal losses of electrolytes ancl water can correct hypoelectrolyternic dehydration and will abolish[all the secondary] disorders. In this study we can be aware that with early detection and appropriate therapy infants with CLI) will achieve adequate growth and development.

PURPOSE: Infection is a major complication in patients with malignant disease. This study was performed to identify the causes and the etiologic agents of febrile infections and to characterize the clinical courses including the response to antimicrobial agents inpediatric cancer patients. METHODS: This study reviewed 274 febrile episodes occurring in 163 children with neoplastic disease which were indentified prospectively at Seoul National University Children's Hospital from January, 1991 to June, 1993. Neutropenia was defined as [granulocyte+band from] < or = 500mm(3). Each febrile episode was classified as a microbiologically documented infection(MDI), a clinically documented infection(CDI), and a probale infection(PI). The responses to initial antimicrobial atents were categorized into improvement, temporary improvement, failure, and not evaluable according to period to defervescence. RESULTS: Seventy seven percent of the febrile epidodes developed in neutropenic state. MDI were 98(36%), CDI 92(34%), and PI 84(30%) episodes. Bacteria were isolated in 75%, viruses in 13% and fungi in 11% of MDI. Fifty two episodes(19% of all) were associated with a bacteremia, and focal infections were indentified in 63% of bacteremia. The most frequent organisms causing MDI were E. coli(22%), K. pneumoniae(15%), S.epidermidis(7%). The great majority of infections other than bacteremia ocurred in the lung(32%), oral cavity(17%), skin and soft tissue(13%), and urinary tract(11%). The frequency of antimicrobial resistance of causative organisms was high. The responses to initial antimicrobial agents were improvement in 49%, temporary improvement in 13%, and failure in 38%. Patients with bacteremia responded less well than those with other categories. Mortality was 7% of total episodes. All of the fatal cases occurred in neutropenia and all but one had hematologic malignancies. CONCLUSIONS: This study documents the etiology and the type of infections and the responses to antimicrobial therapy in children with neoplastic diseases. The changes of causative agents and antimicrobial resistance should be considered in therapeutic strategies of cancer infection.

We report three cases of cystinuria, presenting with urinary stones. A 2-year-old girl presented with urinary difficulty, hematuria, dysuria of sudden onset, and her 7-month-old younger brother also was presented with urinary difficulty, irritability on urination & stone passage. Other 6-month-old boy was admitted due to sudden onset anuria. They had radioopague renal & ureter stones and stone analysis revealed mixed cystine stones. The diagnosis of cystinuria was confirmed metabolic studies and stone analysis. Lrinary amino acid analysis showed excessive excretion of dibasic amino acids(cystine, ornithine, lysine, arginine). And they all had hypercalciuria and hyperuricosuria. They were treated with combination of percutaneous lithotripsy for large obstructing senes a nd an oral drug therapy with sodium bicarbonate for rendering the urine more alkaline, and alpha-mercaptopropionylglycine(ThiolaR). This form of treatment was sucessful in our three cases with elimination of recurrent nephrolithiasis, but in one patient, nephrotic syndrome possibly caused by ThiolaR was developed. The nephrotic syndrome was recovered spontaneously after cessation of Thiola. A review of literatures was also attempted briefly.

A case of recurrent rhinocerebral mucormycosis that has occurred during an induction chemotherapy for acute megakaryocytic leukemia in a 10 year-old boy is reported. He had suffered from high fever, proptosis, right eye ball pain and necrotic inflammation of hard palate during the chemotherapy of leukemia. CT scan of the paranasal sinus showed inflammatory change of right ethmoid and maxillary sinuses, and right orbital cystic mass which displaced medial rectus muscle. Pathologic examination of the inflammatory mass revealed mucormycosis with characteristic hyphae invading vessel walls. He was managed with 2 times of extensive debridement of necrotic tissue and currettage of cystic mass, and intravenous amphotericin-B for 80 days with apparent improvement. Seven months after discharge from the hospital, necrosis of posterior nasal septum and hard palate was noted for second time. It was managed again with 2 times of extensive debridement. Since this last operation he is on follow-up for 16 months uneventfully and is on therapy with low dose Ara-C in continuous remission.
