Congenital laryngeal atresia is a rare cause of airway obstruction that is almost always lethal within a few minutes after birth. Therefore congenital laryngeal atresia should be diagnosed in the prenatal period. If not, it should be considered in newborn infant with life-threatening symptoms at birth such as cyanosis and dyspnea that need emergent procedures like a tracheotomy. We report... |
Purpose : Human umbilical vein endothelial cells(HUVECs) play an important role in regulating blood flow by releasing vasoactive substances. It has been reported that endothelial impairment and dysfunction might be a primary cause of placental vascular disease, which is manifested clinically as preeclampsia in mother and intrauterine growth restriction in fetus. Furthermore, the frequency of apoptotic changes is increased in... |
The 49, XXXXY Klinefelter variant is distinctive; classic findings include mental retardation, hypogonadism and radioulnar synostosis. Its incidence is estimated to be 1/80,000 to 1/100,000 male births. We report a case of 49, XXXXY syndrome confirmed by chromosomal study in neonatal period, whose clinical features included a coarse face, short neck, micropenis, and other multiple minor anomalies including simian creases.... |
Purpose : For the management of patent ductus arteriosus(PDA) in premature infants, fluid restriction, correction of anemia, mechanical ventilation, diuretics, and surgery have been used, and the closure rate of PDA has improved significantly since the introduction of indomethacin and mefenamic acid as pharmacologic treatments of PDA. We studied to evaluate and compare the therapeutic effects of indomethacin and mefenamic... |

Epidermolysis Bullosa Dystrophica (EBD), a subtype of epidermolysis bullosa, is a rare inherited disease characterized by induction of blisters and erosions in skin and mucous membrane by minor or no trauma, which heal with scar formation. Clinical course is more severe in recessive type of EBD than dominant type. We have experienced a case of recessive EBD in a one day old female patient... |

The results are as follows: 1) Most patients (84.5%) were under 4 years of the age. 2) Boys were more prevalent than girls, as a ratio of 1.9:1. 3) Seasonal incidence... |
Citrobacter freundii have been reported infrequently as a cause of meningitis. And, among bacteria that cause meningitis, Citrobacter is unique in its propensity to produced brain abscess. But the pathogenesis of Citrobacter meningitis and brain abscess in humans is unknown. The high prevalance of brain abscess in infants with Citrobacter meningitis mandates cranial computed tomography in every case. The morbidity and mortality rates associated with... |
Life-threatening bacterial infections such as meningitis, septicemia, and pneumonia in the neonates are more common than at any other time in life and signs of these infections are often subtle and non-specific. Because of these factors, the patient who has persistent fever will almost always be started on parenteral antibiotics immediately following evaluation. On the other hand there is also evidence that the hospital... |
Computed tomography is a very valuable method by which the pathogenic evolution of tuberculous meningitis may be followed, thereby facillitating its differential diagnosis and controlling the effi- ciency of therapy, and assessing the degree of hydrocephalus. Fifteen cases of clinically proven intracranial tuberculosis were studied by lateral ventricular indices of brain computed tomography in our hospital during last 3 years. The results were as follows: 1)... |
Chromosomal studies were carried out in 730 patients at the Dept, of Pediatrics and Genetics, Hanyang University Hospital, form December 1979 to April 1986. A statistical assessment was carried out in 244 cases who have chromosomal aberrations. The following results were obtained: 1) Chromosomal aberrations were observed in 244 cases among 730 cases, so the propotion of chromosomal aberrations was 33%. 2) Age distribution revealed 53% of chromosomal... |
We studied prospectively whether events that result in meconium staining may be associated with additional abnormalities that are not clinically apparent associated by measurements of urinary concentrations of β₂-microglobulin indicating renal proximal tubular functions. Among 61 fullterm, healthy neonates delivered at Hanyang University Hospital during the period of September 1986 through April 1987, urinary concentration of β₂-microglobulin and creatinine were measured during the immediate perinatal... |
Although perinatal diagnosis and management has been developed rapidly in recent years, congeni- tal malformations are known to have remained largely unchanged in incidence of infants being delivered. In spite of its clinical significance and physician’s every effort to exclude the possible factors of congenital malformations by perinatal care, there is still no enough statistical data of congenital malformtions in Korea. So, we surveyed to... |
Persistent pulmoanry hypertension of the newborn (PPHN) is a syndrome consisting of severe hypoxemia and pulmoanry hypertension that appears within hours of birth. The essential pathophysiologic features of this syndrome is pulmonary artery hypertension causing right-to-left shunt through the patent ductus arteriosus or foramen ovale or both and clinically manifested by central cyanosis and respiratory distress. We recently have experienced 20 hour old female and... |
We have experienced a case of Potter syndrome recently. He was a newborn infant who suffered from severe respiratory distress soon after birth. His face was characterized by facies renalies and chest X-ray film revealed bilateral pneumothorax. Anuria since birth and findings of abdominal ultrasonography strongly suggested bilateral renal agenesis. Severe respiratory acidosis was progressed in spite of proper management and died at 11... |
Episodic flank or abdominal pain with or without nausea and vomiting is most common manifesta- tion of intermittent hydronephrosis. Between episodes of pain, the patient may be asymptomaitc and intravenous urogram usually will be normal. This condition is diagnosed by intravenous urogram or ultrasonogram taken either during episodes of pain or after hydronephrosis precipitated by use of duretics or ingestion of alcoholic beverage, particulary... |
We experienced a case of holoprosencephaly with extracranial abnormalities, including orbital hypotelorism, median cleft lip without philtrum, flat nasal bridge, flat face, and microcephaly and with a karyotype, 46 XX, 22p+. The diagnosis was confirmed by brain CT scan & brain ultrasonography, and the findings were compatible with an alobar type of holoprosencephaly. The patients died at 26 days of age. A brief review of... |
Since the advent of various antibiotics and wide application of various preventive measure, the childhood mortality due to infectious disease has been declined conspiciously. However, childhood accident has been increasing in recent years and now a days it ranks the leading cause of childhood mortality and morbidity. Because most of the accident are unpredictable and occur suddenly, those result they occupy... |
We exprienced a case of sacrococcygeal teratoma in newborn girl with massive intraabdominalfextensioii and small caudal mass, which is relative rare. |
Jaundice occurs rather frequently in neonatal period, and yet the irreversible complication, kernicterus, may occur in severe cases with pathologic jaundice, from which the patients are at high risk for mental retardation, cerebral palsy, and even death. To prevent this complication, aggressive measures have been used for the neonatal janudice, such as phototherapy and exchange transfusion. Exchange transfusion has been... |
Neonatal period is marked with constantly changing hematologic process due to a number of physiologic and pathologic factors, and with risk of underdiagnosis or misdiagnosis of anemia of various causes. Therefore, prompt diagnosis of anemia and accurate identification of its underlying causes would be essential to arrive at the appropriate management and to avoid occasional serious complications. 104 full term... |
