Purpose : Ureteral duplication is a common urologic anomaly and early diagnosis may prevent irreversible renal damage. We thus aimed to evaluate the benefits of prenatal sonography in early detection. Methods : We retrospectively studied 55 children with duplicated systems who were admitted to Severance Hospital, Yonsei University, Seoul, Korea from January 1998 to July 2003. Results : The mean age at diagnosis was 2.3 years old. 89% of the children had complete duplicated ureter. 47% of the children visited the hospital with an initial complaint of abnormal prenatal sonographic findings. Among these patients, 70.8% had DMSA defects. The mean differential renal function(DRF) in the DMSA scan was 48.2% in the group diagnosed prenatally. In the postnatally-diagnosed group, DMSA defects were found in 67.7% patients and the mean DRF was 45.5%. Conclusion : In comparison with the past studies, the mean age at diagnosis is becoming younger, and the proportion of abnormal prenatal sonography as an initial complaint larger. Other clinical manifestations were similar. The difference of the renal damage between the prenatally diagnosed group and the postnatally diagnosed group was not statistically significant. A multi-center study may help to prove the importance of prenatal sonography in early diagnosis and treatment of ureteral duplication. (J Korean Soc Pediatr Nephrol 2003;7:189-196)

Purpose : The purpose of this study was to describe the epidemiologic features of febrile illnesses in newborns and to predict the risk of serious infections in this population. Methods : A retrospective study was conducted on 123 full-term infants <30 days of age with an axillary temperature >38$^{\circ}C$ who were hospitalized between 2000 and 2006. Neonates with prenatal risk factors, congenital anomalies, antibiotic administration prior to admission to the hospital, or suspected hospital-acquired infections were excluded. We evaluated the symptoms, physical examination findings, laboratory data, and clinical course between the high- and low-risk groups for serious infections. Results : The high-risk group included 30 infants with the following diagnoses in order of frequency: aseptic meningitis, urinary tract infection, bacterial meningitis, infectious enteritis, sepsis concomitant with disseminated intravascular coagulopathy, bacteremia, pneumonia, cellulitis, and omphalitis. Leukocytosis and thrombocytopenia were statistically different between the two groups. Factors, such as moaning signs, seizures, body temperature, and pulse rate were statistically significant. Conclusion : Unlike previous studies, we included newborns with clinical bacterial infections and aseptic meningitis as the high-risk group. Leukocytosis, thrombocytopenia, moaning signs, seizures, and changes in vital signs were considered useful predictors for identifying febrile neonates at high-risk for serious infections in spite of a difference in the definition of serious infection.

The authors would record the fifth case of human fascioliasis in Korea, occurring in a 48 year old Korean man who lived in Munkyong, Kyongsangbuk-do. The diagnosis was based on the morphology and measurements of the eggs which were collected in necrotic debris from the tunnel-like ulcerations of the gallbladder wall which was surgically removed for a gall stone. Although we failed to find out the fluke in the specimen, there found an evidence of once presence of Fasciola in the inflamed wall of the gallbladder in this patient.

We often have difficulties in the diagnosis of acute abdominal pain in children because they are unable to adequately express the characteristics of their pain. With a good understanding of the etiologies of abdominal pain associated with ages, we should create a diagnostic approach based on the location of the pain. First, we must differentiate the surgical abdomen from the non-surgical acute abdomen. Then, we have to identify whether the pain originating from intestinal obstruction, ulcerative diseases, or hepatobiliary dysfunction. It is important to interview and examine the patient serially until the patient completely improves. These attitudes will reduce the patient's pain caused by delayed diagnosis and unavoidable misdiagnosis. Finally, the new insight for the appropriate use of analgesics against acute abdominal pain in children is now needed by the pediatrician.

Chronic diseases as well as a growing population of older adults are currently the leading cause of ill health and economic burden worldwide. Managing those diseases in one-on-one medical consultations poses substantial challenges due to limited time and resources in the current health care system. Various approaches have been taken to manage these conditions, most with limited success. Shared medical appointments (SMAs) are an innovative care delivery option to make the testing of alternative care modalities a prime concern. SMAs are individual medical consultations carried out in a group of patients with similar diseases by providing education, medication management, and disease monitoring. SMAs, since their initial conceptualization in 1998, have gained much popularity and adopted as one of the standard processes in many countries. Accumulated evidence-based studies show outcomes for increasing access to care, behavioral change facilitated through self-management education, maintained/better outcomes, physician productivity, and enhanced resource management. This review summarizes current evidence regarding the existing status of SMAs abroad. An extensive literature search was conducted on major electronic databases including PubMed and Google Scholar. This study suggests to explore and exploit the SMAs which have unique potential as a healthcare delivery innovation in Korea.

Being a medium to help understand the status of the whole body including the Five Vital Organs and the Six Viscera such as the heart, the mac is considered to represent the elasticity of the blood vessel and the condition of the bloodstream in the Oriental medicine. A doctor makes a subjective judgment on a patient's conditions based on the information derived from the diagnosis and the medical examination of the mac wave. Thus he or she needs objective records and make a decision based on them in order to prevent misdiagnosis. This paper set out to suggest the ways to detect the particular parameters of the mac wave with the methods to visualize the mac wave interpretation to detect basic documents(causes) of health status judgment in three-dimension and with the simulation.

Congenital syphilis is a rare cause of non-immune hydrops fetalis. We cared for a neonate with hydrops fetalis who was delivered by emergency Cesarean section due to prolonged fetal bradycardia and ascites at 34 weeks of gestation. He had anemia, purpura, and hepatosplenomegaly, and the serologic tests revealed congenital syphilis (high titers of serum VDRL and TPHA, and a positive serum FTA-ABS IgM). He survived after aspiration of ascitic fluid, ventilator care, and intravenous penicillin therapy. We report a case of non-immune hydrops fetalis due to congenital syphilis with a brief review of literature.

Purpose: This study was conducted to identify the prenatal heath care utilization and expenditure among pregnant women. Method: This was a 5-month follow-up study using a stratified sampling and the data were drawn from the "nationwide claim database of Korean National Health Insurance Corporation". Result: This study found that pregnant women were first diagnosed with pregnancy when they were 7.1 weeks pregnant, received 12.7 times of prenatal examinations and 10.6 times of ultrasonogram. It was revealed that 67.5% of the subjects continued to receive prenatal care at the same medical institutions from the diagnosis of pregnancy to the delivery. The study also showed that the total expenditure of prenatal care per pregnant woman was 700,000 Korean Won (KRW) on average and the insurance coverage rate stood at only 20%. Pregnant women living in metropolitan area spent more on prenatal healthcare expenditure than those who living in medium-sized city or rural area. Conclusion: The results of this study implies that the government needs to provide pregnant women with continuous support by increasing health insurance coverage for prenatal care. Especially, it is considered to provide more support to the pregnant women residing in medically underserved areas.
