OBJECTIVETo study the influence of traumatic subarachnoid hemorrhage on secondary intracranial damage in GCS 13-15 head injuries and prognosis.
METHODSOne hundred and twenty-eight patients with mild head injury, including 64 with subarachnoid hemorrhage and 64 without subarachnoid hemorrhage, were selected and analyzed according to the changes of their conditions after injury.
RESULTSIntracranial abnormality was found in 14 patients (21.87%) with subarachnoid hemorrhage and only in 4 patients (6.25%) without subarachnoid hemorrhage (P<0.01). In the 14 patients, 4 were given surgical treatment. Mild disability was in 2 patients and 2 completely recovered. The rest were conservatively treated and achieved complete recovery at last.
CONCLUSIONSTraumatic subarachnoid hemorrhage, as a factor of intracranial complications in mild head injury should be given much attention. Early drainage of bloody cerebrospinal fluid by lumbar puncture is an effective method for prevention and treatment of complications in mild head injury.

Acute mountain sickness (AMS) occurs commonly in hikers who are rapidly exposed to high altitude environments. Despite the numerous reports of AMS, few studies have reported pallidal lesions associated with altitude sickness. A previously healthy 49-yr-old Korean patient, after ascent to 4,700 m, suffered symptoms consistent with AMS. After returning home, the patient showed changes in personality characterized by abulia, indifference, and indecisiveness. T2 weighted brain magnetic resonance imaging showed high signal lesions involving bilateral globus pallidus. Our case suggests that globus pallidus injury should be included in the differential diagnosis of patients with personality or cognitive change after recovery from AMS.

4.Brain Computerized Tomographic Findings in Various Epilepic Children.
Yonsei Medical Journal 1988;29(4):321-325
Epilepsy is, in some occassions, manifested as one of the symptoms complex of central nervous system diseases, as well as systemic diseases such as metabolic disorders. In 1976, Bachman reported that 33% of epileptic patients manifested abnormal lesions in their computerized tomographic findings. 1005 epileptic children with various types of seizures have been investigated to detect the possible causes of epilepsies. 32% of the patients had abnormal brain C-T findings, of these patients, infantile spasm was the most frequently manifested abnormal C-T finding, rating 52.9%; simple partial seizure, 37.7%; complex partial seizure, 36.1% and generalized seizure, 27.1%, in order of frequency. Curable lesions, such as tumor, granuloma and arachnoid cyst were detected by brain C-T scan, and a brain tumor was detected in 2% of the patients. The brain C-T scan is one of the most effective diagnostic tools to evaluate the underlying lesions of the central nervous system of epileptic children.

The medical records of six cases of nesidioblastosis were examined to determine the diagnostic approach, treatment, and neurologic sequelae. All six patients were male, and their ages at the onset of the disease ranged from one day to six months (mean 3.36 +/- 2.5 mo.). Initial clinical features were seizure, cyanosis, poor feeding, and apnea. Other subsequent symptoms were developmental delay, hyperactivity, and cold sweating. The Birth weight of the neonatal onset group was heavier than the postneonatal onset group (4.4 +/- 0.3 vs 3.26 +/- 0.04 kg). Before the diagnosis of hyperinsulinism, steroids of ACTH proved effective for seizure control. Initially, hyperinsulinemia (serum insulin greater than 10 microU/ml) was detected in four cases, but another two cases also showed hyperinsulinism by insulin/glucose(I/G) ratio greater than 0.3 during the fasting test. The glucagon response performed in 2 cases, showed normal and partial responses. Euglycemia was obtained by near total pancreatectomy (95% pancreatic resection)without malabsorption or persistent diabetes. In one case, nesidioblastoma coexisted with nesidioblastosis. Developmental delay was noted in three cases. In this group, the mean duration between symptom onset and operation was longer than the group without developmental delay (1.25 +/- 0.47 vs 0.38 +/- 0.19 yr).

OBJECTIVETo investigate the clinical manifestations, imaging characteristics as well as prognosis of neonatal polycythemia complicated with brain damage.
METHODSOne hundred and sixteen in-patients with neonatal polycythemia admitted to our hospital during January 2003 to October 2005 were analyzed. Their clinical manifestations were observed. Craniocerebral ultrasonic examination (2D, 3D), CT and MRI were employed to dynamically observe the craniocerebral imaging variances as well as the cerebral hemodynamic variations and near infrared spectroscopy (NIR) was adopted to test the cerebral oxygenation. Twenty-two cases with moderate or severe disease were followed up for 3 to 12 months.
RESULTSOut of the 116 polycythemic neonates, 53 cases had brain damages, of whom 31 had mild, 14 had moderate, and 8 had severe damages. Cranial imaging alterations were mostly ischemic injuries of various areas of different severity. The severity of brain damage was closely related to the duration of polycythemia, oxygen saturation of cerebral tissues as well as cerebral hemodynamic abnormalities. Brain injury was likely to occur in those whose polycythemia persisted for more than three days. The regional saturation of oxygen (rSO(2)) in mild brain injury cases was found to be 52.1%, while it was 47.1% in moderate and severe brain injury cases. Compared to the 58% as found in non-brain injury cases, the variance was found to be statistically significant (F = 104.466, P < 0.01). Among the cases with brain injury, cerebral hemodynamics displayed a slowdown in the blood flow velocity in the cerebral anterior artery and medium artery during the systolic phase and/or the diastolic phase. The abnormality ratio was closely related to the severity of brain injury. Through the chi(2) test the variance was proved to be statistically highly significant (chi(2) = 18.889, P < 0.01), however it was not correlated with the increase of the initial levels of hemoglobin (Hb) and hematocrit (HCT) (P > 0.05). During the follow up, neurological developmental abnormalities of various severity were found to exist in the cases with moderate (5/12) and severe disease (7/8), while cerebral palsy or epilepsy was not yet found.
CONCLUSIONNeonatal polycythemia might tend to bring about a reduction in the perfusion of cerebral blood flow and damaged cerebral oxygenation metabolism which in turn might lead to cerebral ischemic injury, which in some of the moderate and severe cases might lead to long-term neurological complications. Imaging investigations especially craniocerebral ultrasonic examination could be the practical means for the early diagnosis and evaluation of prognosis.

OBJECTIVETo study the dose- and time-dependent protective effects and the synergistic effects of nimodipine (NMDP) and fructose-1,6-diphosphate (FDP) against cerebral damage induced by acute carbon monoxide (CO) poisoning in mice.
METHODSMale mice were exposed to CO 170 mL/kg, i.p. After CO intraperitonealy exposure, mortality of mice, change in memory function estimated by passive avoidance test, the pathomorphologic observation of brain tissue slices, as well as changes of activities of monoamine oxidase (MAO)-B and Ca(2+)-Mg(2+)-ATPase in cerebral tissue were studied. In dose-dependent protective effect study, NMDP (10.6, 5.3, 2.7 mg/kg) and FDP (2.6, 1.3, 0.67 g/kg) was injected ip, respectively 15 min after CO exposure. To study the time-effect relationship of drugs, NMDP (5.3 mg/kg) and FDP (1.3 g/kg) were administered ip respectively 15 minutes, 45 minutes and 120 minutes after CO exposure. The combination of NMDP (2.7 mg/kg) and FDP (0.67 g/kg) was administered ip15 minutes, 45 min and 120 minutes after CO exposure to study the synergism of the two drugs.
RESULTSEither NMDP (10.6, 5.3 mg/kg) or FDP (2.6, 1.3 g/kg) administered ip within 15 minutes after CO exposure significantly decreased the impairment of memory function and mortality rate induced by CO, inhibited the decrease of Ca(2+)-Mg(2+)-ATPase activity, blunted the rising of MAO-B activity and prevented the delayed hippocampal neuronal death in poisoning mice. To our surprise, the combined use of NMDP (2.7 mg/kg) and FDP (0.67 g/kg) within 15 minutes after CO exposure had similar effects to that in NMDP (10.6, 5.3 mg/kg) and FDP (2.6, 1.3 g/kg).
CONCLUSIONSThese results suggest that the impairment of CO on brain can be attenuated if NMDP or FDP are administered sufficiently and quickly as soon as possible after CO exposure and there exists a synergism of FDP and NMDP against CO poisoning damage.

Journal of Korean Medical Science 2010;25(Suppl):S87-S93
We searched databases and used various online resources to identify and systematically review all articles on occupational psychiatric disorders among Korean workers published in English and Korean before 2009. Three kinds of occupational psychiatric disorders were studied: disorders related to job stress and mental illness, psychiatric symptoms emerging in victims of industrial injuries, and occupational psychiatric disorders compensated by Industrial Accident Compensation Insurance (IACI). Korea does not maintain official statistical records for occupational psychiatric disorders, but several studies have estimated the number of occupational psychiatric disorders using the Korea Workers' Compensation and Welfare Service (COMWEL, formerly KLWC) database. The major compensated occupational psychiatric disorders in Korea were "personality and behavioral disorders due to brain disease, damage, and dysfunction", "other mental disorders due to brain damage and dysfunction and to physical diseases", "reactions to severe stress and adjustment disorders", and "depressive episodes". The most common work-related psychiatric disorders, excluding accidents, were "neurotic, stress-related, and somatoform disorders" followed by "mood disorders".
