Purpose : Fragile X syndrome is an X-llinked genetic disorder and is characterized by mental retardation, learning disability, behavior disorder, and autism with typical elongated face, large ears, and macro-orchidism. Recent reports have focused attention on the EEG finding of this syndrome, which is a particular paroxysmal pattern during sleep(mono or diphasic centrotemporal spikes) and awake state(background slowing). In this study, we analyzed the clinical... |
Purpose : The importance of trace elements in their effect on the physiology and pathology of the central nervous system is well recognized. Changes in the concentrations of these elements in the brain could take place in pathological states. Recently, a greater emphasis has been given to the role of trace elements in the function of the nervous system both in normal and pathological... |
Purpose : This is to analyze epidemic and clinical features of acute respiratory tract infections(ALRTI) by respiratory syncytial virus(RSV) and parainfluenza virus(PIV), which are considered to be the major respiratory pathogens in children. Methods : Nasopharyngeal aspirates were collected from 515 patients with ALRTI hospitalized at Hangang Sacred Heart Hospital between Apr. ’94 and Oct. ’96. Nasopharyngeal aspirates were inoculated to... |
Purpose : In the Summer 1996, there was an outbreak of aseptic meningitis without sequele. 116 cases who were admitted to our Department during a six month period from May to October, 1996. Therefore, we report epidemic of aseptic meningitis in 1996 and analyze and compare it with a epidemic of aseptic meningitis in 1993. Methods : We studies about clinical manefestation and laboratory finding... |
Purpose : Studies done in Western societies have described characteristics of infant crying behavior. These include:crying peak in the second month, diurnal rhythm(typified by clustering during evening hours) and crying that is robust to differences in caretaking styles. This survey was undertaken to compare the crying patterns of Korean babies with those of their Western counterparts. Methods : From June 1995 to March 1996, well... |
Purpose : Lipids and fatty acids are very important for brain and nervous system in growing children. This study was carried out to compare the composition of serum lipids and fatty acids according to the type of feeding in children. Methods : One hundred and twenty two children aged from 5 month to 24 month who visited Soonchunhyang University Hospital from Mar. 1995 to... |
Purpose : Ugly ulcer and keloid formation of injection site has sometimes been a problem in Korea from the cosmetic point of view in intradermal vaccination. Since 3 or 4 years ago, multipuncture BCG vaccination has been used in Korea, there are no data and information about multipuncture BCG vaccination. We therefore performed this study to evaluate of conversion rate, complication and to make... |
Purpose : This study was carried out to evaluate the role of the septal leaflet of the tricuspid valve. The hypothesis was that the neonatal tricuspid regurgitation(TR) was related to a transient elevation of right ventricular pressure in the neonatal period, that deviated ventricular septum and pull the anchored septal leaflet of the tricuspid valve. The pulled septal leaflet created the incomplete coaptation between... |
Purpose : We studied prevention effects of vertical transmission of Hepatitis B with follow-up, through the change of Anti-HBs titers during 9 months after injection of Hepatitis B immunoglobulin(HBIG) and Hepatitis B vaccine(HBV) at birth in newborn delivered from Hepatitis antigen carrier mothers. Methods : This study was performed on newborn delivered from HBsAg carrier mothers at Hae Sung Hospital from Feb. 1995 to May... |
Purpose : An excess of GH causes various problems within the cardiovascular system including cardiac hypertrophy and abnormalities of left ventricle(LV) function. To evaluate the cardiovascular effects due to GH treatment in idiopathic short stature (ISS), we measured the cardiovascular function. Methods : Twenty-two echocardiographic studies were performed in ISS who were admitted from Jan. 1994 through Jul. 1996, and they were divided into two... |
Down syndrome is the most common autosomal syndrome in man. The incidence of trisomy 21 due to translocation is about 3.5-5%. Translocations are usually centric fusions between a 21 and a D group (54.2%) or a G group (40.9%) chromosome. Since the short arm of 21 carries no phenotypically active genes, even if the short arm of 21 is lost, usually there is... |
The clinical significance of Yersinia pseudotuberculosis(Y. pseudotuberculosis) has recently recognized in various part of the world because it can cause a wide range of clinical problems such as mesenteric lymphadenitis, septicemia, reactive arthritis, terminal ileitis, erythema nodosum and acute renal failure. we experienced a case of acute renal failure associated with Y. pseudotuberculosis infection. We applied a nested polymerase chain reaction method for rapid diagnosis... |
Herpes zoster, an inflammatory human disease caused by varicella zoster virus, is characterized by papulovesicular lesions along the distribution of a sensory nerve. We experienced a herpes zoster in 23 day old premature infant. The papules were distributed on his skin corresponding to the dermatomes innervated by the left Th3-Th4. The diagnosis of herpes zoster was made with dermatomal distribution of typical skin lesions, pathologic... |
Neuronal migrational disorders of the brain represent abnormalities in the formation of the neocortex caused by faulty migration of the subependymal neuroblasts. The neuroblasts normally migrate between the sixth and 15th gestational week and in doing so form the six-layered neocortex. When the migration does not occur in a normal fashion the resultant brain anomalies include lissencephaly, pachygyria, schizencephaly, hemimegalencephaly, heterotopia, and polymicrogyria. Neuronal heterotopia is... |
Ectopic pancreas is a rare congenital anomaly defined by the presence of pancreatic tissue that lacks anatomic and vascular continuity with the main body of the pancreas. A 11-year-old girl was admitted to the Department of Pediatrics, Yonsei University College of Medicine with the history of recurrent abdominal pain for 2 years. We performed fiberoptic endoscopy which showed a 1.5¡¿1.5cm sized polypoid mass, and... |
