PURPOSE: Headache is a frequent symptom in pediatric practice, but the prevalence of chronic recurrent headache was estimated in several studies with wide variations, because of inadequate expression and differences in case definition in children. Headache classification of International Headache Society is usually used in adults, but the application of it to children is uncommon, so we tried to diagnosis children with headache by using International Headache Society Classification. METHODS: We analyzed the clinical pictures, physical examinations including neurologic examination, PNS series, EEG and CT or MRI in 53 children with nonprogressing recurrent headache over than one month, who visited to pediatric department of Dong-A University hospital from January, 1995 to Feburary, 1996 and diagnosed them by using International Headache Society Classification. RESULTS: 1) The sex ratio between male and female was 1:1.2. 2) Diagnosed groups consisted of children with migraines in 22 cases(41.5%), tension-type headache in 19 cases(35.9%), coexisting migraine and tension-type headaches in 5 cases(9.4%), miscellaneous headaches not associated with structual lesion in 1 case(1.9%), headache associated with vascular disorders in 2 cases(3.8%), headache associated with nonvascular intracranial disorder in 1 case(1.9%), headache due to facial pain in 3 cases(5.6%). 3) Of 22 migraine cases, 13 cases(59.1%) had migraine with aura, 8 cases(40.9%) have migraine without aura and of 19 tension-type headache cases, 8 cases(42.1%) have episodic type, 11(57.9%) cases have chronic type. 4) Of 53 cases with recurrent headache, 3 cases(6%) had abnormal findings in CT or MRI. 5) Of 53 cases with recurrent headache, 9 cases(17%) had abnormal findings in EEG. CONCLUSIONS: International Headache Society Classifications are useful, but the diagnostic criteria are too strict for children, especially in migraine and tension type headache.

PURPOSE:This study was performed to elucidate that status epilepticus (SE) induces long- term neuronal damages in an immature brain and to evaluate that topiramate (TPM) has a protective effect. METHODS:We investigated the changes in a subtype expression of glutamate and gamma- amino butyric acid (GABA) receptors, and the structural integrity due to cell losses in the mouse pup hippocampus after SE using an immunoblot and confocal microscopy. RESULTS:SE induced significant cell losses with structural changes in the hippocampus 1 month later. SE up-regulated the glutamate receptor1 (GluR1) expression with an increased ratio of GluR1 to glutamate recptor2 (GluR2), leading to the formation of Ca2+ permeable alpha- amino-3-hydroxy-5-methyl-4-isoxazoleepropionic acid (AMPA) receptors for the enhanced neurotoxicity. TPM prevented the SE-induced GluR1 expression. The expression of GABAA receptors was highly increased 1 month after SE, whereas that of GABAB receptors was not changed. The TPM treatment attenuated SE-induced upregulation of GABAA receptors. SE induced significant cell losses and disruption of structural integrity in the hippocampus CA1 and CA3 regions, but the TPM treatment for 1 month in developing brains reduced the SE- induced hippocampal damage. CONCLUSION:TPM has a neuroprotective action, which might be mediated by the modulation of GluR1 and GABAA receptors.

PURPOSE: To determine whether febrile seizure enhances neuroexcitability by altering synaptic transmission and whether febrile seizure-induced hyperexcitability leads to long-lasting neuronal death. METHODS: We investigated the expression of synaptic and postsynaptic proteins and the apoptosis of neuronal cells in rat pup hippocampus after hyperthermic seizure using immunoblotting and confocal microscopy. RESULTS: Hyperthermic seizure enhanced the long-term expressions of presynaptic proteins such as syntaxin, VAMP, SNAP-25 and nSec1, whereas that of NSF was decreased. The expressions of postsynaptic NMDA receptors 1, 2a and 2b were up-regulated. The expression of postsynaptic AMPA glutamate receptors 1 month after hyperthermic seizures altered by way of increasing the ratio of GluR1 to GluR2 and decreasing NSF-GluR2 interaction, which leads to the formation of Ca2+permeable AMPA receptors and enhanced toxicity. However, in spite of enhanced neuroexcitability, there was a transient increase of neuronal death in hipocampus one week after hyperthermic seizure, but returned to baseline one month later. CONCLUSION: These results demonstrate both presynaptic and postsynaptic forms of long-term enhancement of glutamate synaptic transmission after hyperthermic seizure and support the idea that early-life febrile seizure might have persistent effects on neuronal excitability in the hippocampus.

Journal of the Korean Child Neurology Society 2006;14(1):38-44
PURPOSE: This study was undertaken to determine the incidence and the meaning of epileptiform discharges accompanied by chronic recurrent headaches. METHODS: We selected 449 cases of children who visited Dong-A University Hospital because of recurrent headaches from January 1999 to July 2005. The headaches were classified by the criteria established by the International Headache Research Committee in 2004. The electroencephalography was performed in 336 cases and 36 cases who showed epileptiform discharges were selected. We studied the characteristics of epileptiform discharges, MRI findings and the relationship with epilepsy. RESULTS: The incidence of interictal epileptiform discharges(ILEDs) of the patients with chronic headaches was 10.7%, which was higher than that in a normal population. In the location of ILEDs, focal areas(9.2%) were more common than general areas(1.5%). The incidence of the ILEDs was different according to the types of headaches(P<0.01). The focal ILEDs were concentrated at the central temporal areas. The most common type of ILEDs was frequent epileptiform discharges(63.9%). For the wave forms of ILEDs, focal spike activities were 83.3%, and bursts of slow waves mixed with spikes were 13.9%. Among the 36 cases that showed the ILEDs, 2 cases were associated with epilepsy and another 2 with AV malformation on the MRI images. CONCLUSION: The ILEDs of the patients with chronic recurrent headaches mainly occurred in the central temporal areas as focal spike wave forms, which shows a benign course. Because a few cases can accompany epilepsy and brain abnormalities, close observation and follow-up tests are needed.

About a third of the patients with decompensated liver cirrhosis have reduced arterial oxygen saturation and are sometimes cyanosed in the absence of any apparent lung or heart disease; There is a reduction of diffusing capacity without a restrictive ventilatory defect. The aim of this study was to determine diffusing capacities in patients with chronic liver- diseases. The diffusing capacities and arterial oxygen saturations were measured in 25 patients with chronic active hepatitis(CAH), 9 early cirrhotics (early LC), 36 cirrhotics(Child's class A) and 11 cirrhotics(Child's class B). The anterior tibial area was observed for pitting edema, and Thallium-201 test per rectum(shunt index) was done. Hypoxemia was not observed in all subjects. The number of cases with decreased pulmonary diffusing capacity (DLco) is 3/25(12.0%) for CAH, 3/9(33.3%) for CAH with early liver cirrhosis(LC), 17/36(47.2%) for LC(Child's class A) and 6/11(54.5%) for LC(Child's class B). The mean+/-standard deviation of Dlco(% predicred) are 93.1+/-12.1 for CAH, 85.7+/-12.3 for CAH with early LC, 82.2+/-14.7 for LC(Child's class A) and 80.4+/-6.9 for LC(Child's class B), There is a significant difference between DLco in CAH and that in LC(Child's class A)(p<0.01). Patients with higher shunt index(>0.3) had significantly lower DLco than these with lower shunt index(<0.3)(76.4+/-9.7% vs. 89.3+/-13.3%)(p<0.01). The DLco was also lower in patients with pitting edema(77.3+/-10.2%) than in those without pitting edema(85.5+/-13.8%) (p<0.01). These results summarized that the DLco was low in patients with cirrhosis and with higher shunt index(>0.3) or pitting edema. This may be due to an increased systemic blood flow shunt and an increased generalized interstitial edema. Pulmonary function tests including diffusing capacity may be useful as prognostic parameters in patients with chronic liver disease, especially in those with CAH or early LC.

OBJECTIVE: Morphometric data on dorsal cervical anatomy were examined in an effort to protect the nerve root near the lateral mass during posterior foraminotomy. METHODS: Using 25 adult formalin-fixed cadaveric cervical spines, measurements were taken at the lateral mass from C3 to C7 via a total laminectomy and a medial one-half facetectomy. The morphometric relationship between the nerve roots and structures of the lateral mass was investigated. Results from both genders were compared. RESULTS: Following the total laminectomy, from C3 to C7, the mean of the vertical distance from the medial point of the facet (MPF) of the lateral mass to the axilla of the root origin was 3.2-4.7 mm. The whole length of the exposed root had a mean of 4.2-5.8 mm. Following a medial one-half facetectomy, from C3 to C7, the mean of the vertical distance to the axilla of the root origin was 2.1-3.4 mm, based on the MPF. Mean vertical distances from the MPF to the medial point of the root that crossed the inferior margin of the intervertebral disc were 1.2-2.7 mm. The mean distance of the exposed root was 8.2-9.0 mm, and the mean angle between the dura and the nerve root was significantly different between males and females, at 53.4-68.4degrees. CONCLUSION: These data will aid in reducing root injuries during posterior cervical foraminotomy.

Hydranencephaly is a rare condition in which the brain's cerebral hemispheres are absent and replaced by sacs filled with cerebrospinal fluid. The prognosis for children with hydranencephaly is generally poor, so many children with this disorder die before the age of 1 year. We experienced a patient with hydranencephaly who showed prolonged survival until age of 22 years. To our limited knowledge, this case may be the longest survival of a patient with hydranencephaly in the world.

Purpose:
This study compared the clinical and radiological results of the femoral neck system (FNS) and cannulated compression screws (CCS) for the fixation of femoral neck fractures.
Materials and Methods:
Patients who underwent FNS or CCS internal fixation for femoral neckfractures between January 2016 and January 2022 were analyzed retrospectively. The hip joint function using the Harris hip score (HHS) was evaluated three months and one year after surgery. The operation time, fracture healing time, and associated surgical complications in the two groups were compared and analyzed statistically.
Results:
Seventy-nine patients were categorized into 38 FNS and 41 CCS groups. The FNS group had a longer operation time and higher postoperative HHS at three months (p<0.01). Femoral neck shortening was lower in the FNS group (p=0.022). There were no significant differences in the fracture healing time and other complications.
Conclusion
There were no differences in most clinical outcomes and complications between the two groups except for the three-month HHS and femoral neck shortening. This study suggests that FNS could be an alternative to CCS for treating femoral neck fractures.

OBJECTIVES: Two related cases of Hemolytic-Uremic Syndrome (HUS) were reported to the Korea National Institute of Health in May, 2001. Shiga toxin 2 genes were detected in both stool samples. We suspected an enterohemorrhagic Escherichia coli (EHEC) infection as the cause of the HUS, and conducted an investigation to find the source of the infection and its route of transmission. METHODS: We performed case investigations on these two related HUS cases, and obtained interviews and rectal swabs form the family members and other close contacts. Additionally, we performed rectal swabs on the cattle raised by the household of the index patient. RESULTS: We found a 20 month old index patient and a 6 year-old cousin had developed HUS, where there had been a 2 day history of contact with the index, and bacteriological examinations for these two patients revealed, indistinguishably, the same E. coli O171. The grandmother of the index patient was found to be asymptomatic, but E. coli O26 was isolated. We also found a probable case in the mother of the cousin. She reported a history of contact with the index, and developed bloody diarrhea of 3 days duration. The test results for the cattle revealed E. coli O26 in one cow, and E. coli O26 and O55 in another. E. coli O26, which was isolated in both cows and the grandmother of the index, were indistinguishably the same. CONCLUSIONS: We found that the E. coli O26 in the grandmother had originated from the cows, and that the E. coli O171 found in the index patient had been transmitted to the cousin through person-to-person contact.

In this study we present a case of an angiocentric T-cell lymphoma (ACTL) which involve the esophagus. A 37-year-old male was admitted with dysphagia, odynophagia, and weight loss for 3 months. Two months before his admission, he had undergone on endoscopy with a biopsy. The first endoscopic findings revealed a large ulcerative lesion on the esophagus, although there had been no evidence of lymphoma upon microscopic examination. On the follow up endoscopic examination, this ulcerative lesion revealed progressive and destructive change. Histopathology of the third biopsied specimens showed large atypical lymphocyte infiltrates with angiocentric and angioinvasive features. Immunohistochemical studies revealed that the atypical (large) lymphocytes had T-cell phenotypes (CD3+, CD5+, and CD43+) and contained few reactive B-cells (CD20+), We assume that this is the first case of ACTL involving the esophagus and larynx.
