| Purpose : The aim of this study was to evaluate clinical differences by karyotype in Turner Syndrome. Methods : We evaluated 66 patients with Turner syndrome diagnosed at Yonsei University College of medicine from Mar.1985 to Feb.1993. We divided subproups as pure 45,X groups, mosaisism groups and structural aberration groups. Clinical features, serum estrogen, LH, FSH, concentrations, gonadotropin release after GnRH... |
| The hyperlipoproteinemias are the disturbance of lipid transport resulted from accelerated synthesis or retarded degradation of lipoproteins that transport cholesterol and trigycerides through plasma. These diseases are classified as type I, type IIa, type IIb, type III, type IV, type V, and hyper-α-triglyceride levels due to increases in both VLDL and chylomicrons and lipoprotein electrophoresis shows increases pre-β, β, and... |

PHA type I, subdivided into isolated renal insensitivity to aldosterone of autosomal dominant inheritance and multiple target organ defect of autosomal recessive inheritance, and PHA type II show similar clinical manifestations except hypertension which is limited to type II. PHA type I is charaterized by hyponatremia, hyperkalemia,... |
| Pseudohypoaldosteronism type 1 is a genetic renal tubular disease of salt wasting, presenting in young infants. Tubular unresponsiveness to elevated endogenous an exogenou aldosterone is the suggested pathogenetic mechanism. Oral sodium chloride supplementation relieve the clinical symptoms and electrolyte distrubances. We experienced 2 cases of PHA type 1 in 38-day and 450day old male infants who were presented with failure to... |

Absence of both lung is very rare and is incompatible with life. Unilateral or bilateral agenesis of the lung often associated with the skeletal, cardiovascular, gastrointestinal and genitourinary anomalies. H-type tracheoesophageal fistula in... |

The results of brain CT in 204 children with seizure were evalu-ated in relation to the age of onset, according to seizure type, and final diagnosis of abnormal fi ndings by CT scan. The following results were obtained. 1) Out of 204 cases,... |
| The term "duplication" should be used when describing those spherical or tubular structures found along the alimentary tract whose walls contain well-devoloped muscular layers and whose lining is a mucosa similar to that of some part nf the alimentary tract. Symptoms produced by these lesions usually vary according to their location, their size, and the type of fluid secreted by their... |

The patient was a 4 day-old female infant with irregular, grouped vesicobullous lesions on the whole body, especially on the trunk and extremities since birth. No familial traits was noted. Diagnosis was made by the charateristic clinical, labaratory and histopathologic findings. |
| Almost of all patients with neurofibromatosis type I show caf6-au-lait macules on their skin. These macules are thought to be early sign of neurofibromatosis in childhood. We experienced a case of neurofibromatosis type I in a 10-year-old-boy who did not have caf6-au-lait macules, but progressive psychomotor retardation, short attention span, hyperactivity and megalencephaly. The brain C-T findings showed diffuse cerebromalacia and ventriculomegaly. We confirmed the... |
| Phenotypes and • gene frequencies in cord blood samples of 543 newborns were studied for Pi phenotypes for the purpose of estimating the risk of diseases associated with genetic deficiency of alpha-1 antitrypsin. Pi phenotypes were performed by polyacrylamide gel separator isoelectric focusing method. The allele frequencies obtained were as follows:'PiM!=0.7670, M2=0.1796 M3=0. 0506, G=0.0018,/P=0.0009. There were no alleles causing severe deficiency such as... |

Characteristic coarse facial features, gum hypertrophy, retarded growth and dysostosis multiplex were observed in both cases. Under phase contrast microscopic examination, cultured fibroblasts of skin of case I patient had their cytoplasm filled with numerous dark granules leaving only a juxtanuclear crescent free of inclusions. We report... |
