The large size and vascularity of the neonatal adrenal glands are vulnerable to traumatic and asphyxial injuries. This condition varies in presentation, which the most common is an abdominal mass alone or mass with jaundice and anemia. Some infants show signs of adrenal insufficiency. Abdomial ultrasonogram is the most valuable diagnostic tool. To result in adrenal insuffiency, hemorrhage must involve both adrenals and at least 90% of the adrenocortical tissue must be destroyed. To affect infant may show signs of hypovolemic shock, electrolyte imbalance and metabolic acidosis. Treatment for adrenal insufficiency must be immediate and vigorous, and consists of intravenous glucose, fluid, and electolyte replacement. And conservative treatment failure is candidate for steroid replacement. We experienced a case of bilateral hemorrhage with adrenal insufficiency, who improved with hydrocortisone.

Chronic recurrent multifocal osteomyelitis(CRMO) is an unusual inflammatory process involving multiple osseous sites. No causative agent can be consistently isolated from these lesions despite multiple biopsies and the affected child purses a clinical course of chronic remissions and exacerbations independent of antibiotic therapy. Biopsy of the lesions did not reveal any pathogens. Immunologic investigation revealed no abnormality common to the patient and there was no indication of a genetic etiology. The natural history of chronic recurrent multifocal osteomyelitis appears to be slow, spontaneous resolution of the osseous lesions without specific treatment. We experienced a case of CRMO in an 11-year-old girl who had complained of fever, pain on knee and wrist joints for several weeks. We studied the clinical, radiographic, histological findings in this patient and we report a case of CRMO with brief review of related literature.

Incontinentia pigmenti (IP) is a rare multisystemic ectodermal disorder, which is characterized by vesicular, verrucous, and pigmented cutaneous lesions, and is frequently associated with various developmental defects of the eye, CNS, teeth, hair, and nail. It is regarded as an X-linked dominant genetic disorder. We recently experienced a case with IP, who presented with irregular, reticular, and slate-gray to brown colored pigmentation on the whole body at birth. Skin lesions were much improved by 6 month of age. The mother of this infant had the history of same cutaneous lesions in her neonatal period, suggesting that these lesions had familial tendency.

PURPOSE: The human fetus is primarily dependent on the placenta for its nutrition. However, as the fetus matures, it swallows increasing amounts of amniotic fluid, which contributes to the growth of fetus. Accordingly fetuses with congenital obstruction of the gut at high level have a reduced capacity for intestinal absorption of amniotic fluid. We undertook a study to investigate the effect of congenital gut obstruction on fetal growth. METHOD: A retrospective review of the records of all patients presenting congenital gut obstruction over 6-year period (from 1992 to 1997) in Chung-ang Gil hospital was performed. Patients with a complete proximal obstruction were included in group A; patients with incomplete or lower obstruction were included in group B. RESULT: 1) The ratio of male to female was 1.5:1. The mean birth weight and gestational age were 2.89+/-0.60kg and 38.7+/-0.20weeks. The mean birth weight and gestational age in group A were 2.68+/-0.69kg and 37.8+/-0.25weeks. The mean birth weight and gesnal age in group B were 2.980.54kg and 39.1+0.17weeks. There was significant difference between group A and B (P<0.01). 2) Significant differences were found between group A and B in prematurity and growth retardation rate (P<0.01). No significant difference was found between group A and B in associated anomaly rate (P>0.05). 3) In group A, 3 (42.8%) of 7 patients with associated anomalies had IUGR, whereas 8 (40.0%) of 20 patients without associated anomalies had IUGR (P>0.05). The corresponding figures for group B were 23.0% and 14.8%, respectively (P>0.05). CONCLUSION: Congenital gut obstruction causes IUGR by reducing intestinal absorption of amniotic fluid and the effect of IUGR is more pronounced as the obstruction is proximal to jejunum rather than distal to it.

PURPOSE: Hypoxic-ischemic encephalopathy is a major neurologic problem and one of the most important perinatal causes of neurological morbidity. Evaluation of the presence, extent, and subsequent evolution of hypoxic-ischemic lesions may be very important. We studied the significance of imaging modality through the analysis of brain MRI findings of hypoxic-ischemic encephalopathy during neonatal period and comparison with findings of brain ultrasonography. METHODS: We analysed the forty-seven infants retrospectively who were diagnosed as hypoxic-ischemic encephalopathy and underwent brain MRI and ultrasonography from Jan. 1992 to May 1996. RESULTS: 1) The mean gestational age and birth weight of the twenty-seven infants who were premature were 32.8+/-2.08weeks and 1.97+/-0.44kg respectively. The mean gestational age and birth weight of twenty infants who were fullterm were 39.3+/-1.04weeks and 2.98+/- 0.93kg respectively. The primary hypoxic-ischemic insults occurred during antenatal, intrapartum and postnatal period. 2) The findings of brain MRI were classified into periventricular leukomalacia, encephalomalacia, basal ganglia lesion, focal parenchymal hemorrhage, ventriculomegaly without other lesion and normal finding. 3) Three infants among twenty-five infants with periventricular leukomalacia, four infants among seven infants with basal ganglia lesion and six infants among seven infants with focal parenchymal hemorrhage were not diagnosed by brain ultrasonography. 4) All of ten infants with encephalomalacia and four infants with ventriculomegaly without other lesion were diagnosed by brain ultrasonography. CONCLUSIONS: MRI can diagnose the hypoxic-ischemic lesions which would not be possible by brain ultrasonography. Therefore MRI is the imaging modality of choice for diagnosis in infants with hypoxic-ischemic encephalopathy. We believe that the benefits of MRI outweigh its somewhat higher cost, lack of portability and monitoring difficulties.

PURPOSE: Acute immume thrombocytopenic purpura (ITP) is relatively common hematologic disease in children. Most acute ITP is recovered within 6 month spontaneously and the complication is rare. But 10~20% of the ITP patient became a chronic form. Infection with Epstein-Barr virus (EB virus) in developing country usually occurs during infancy and early childhood. Acute ITP associated with EB virus is likely to develop chronic ITP in current literatures. We studied the pattern of laboratory findings in long term follow up of ITP with EB virus infection. METHODS: One hundred and seventy nine patients diagnosed with ITP admitted to the division of pediatric hematology, Gachon Medical Center and Hanyang University Hospital between Mar. 1991 and Jun. 2001 were reviewed retrospectively. Serologic test for EB virus was available for 57 patients and 25 of them were follow up at least 6 months. Evidence of acute EB virus infection was defined as a positive Viral Capsid Antigen (VCA) IgM or positive Anti VCA IgG and negative Ebstein-Barr virus Nuclear Antigen (EBNA). Complete remission (CR) was defined as a recovery of platelet count of more than 100 109/L and partial remission (PR) as a recovery of platelet count of 50~100 109/L, maintained for at least 6 months. RESULTS: Sixteen out of 57 patients were associated acute EB virus infection. Of this group, 8 patients were follow up at least 6 months. Forty one of 57 with no evidence of acute EB virus infection, 17 were follow up at least 6 months. The clinical and laboratory data was not different significantly in children with and without acute EB virus infection in admission. In EB virus infection group of 6 months follow up, platelet count was significantly lower than control group in 6 months follow up (P=0.006). Five patients of 8 (63%) with acute EB virus infection had chronic ITP and 2 of 17 (12%) with no evidence of EB virus infection had chronic ITP in follow up 6 months. CONCLUSION: Patients with EB virus associated ITP tended to resolved more slowly than those without EB virus infection and also showed tendency to become chronic ITP.
