We present a study on the systemic insults in the early death(within one week) after head injury. The patient population consisted of 192 patients who were admitted to the Soonchunhyang University Chonan Hospital from August 1986 to May 1990 after head injury. We collected clinical features and systemic insults including blood pressure, arterial pH, PaO2, PaCO2, hematocrit, and serum concentration of Na, retrospectively. The most common cause of injury was road traffic accident(77.6%). More than half(57.8%) were under the age of 40 years. The interval from injury to admission was within one hour in 63.2%, and within four hours in 91.4%. The mean interval was 1.8 hours. However, in 154(80.2%) patients, we found the evidence of systemic insults on admission. We found hypotension(ststolic less than 90mmHg) in 22.9%, acidemia(pH<7.35) in 71.3%, arterial hypoxemia(PaO2<60mmHg) in 42.7%, hypercarbia(PaCO2>45mmHg) in 28.7%, anemia(hematocrit<30%) in 13.0%, hyponatremia(Na<135mEq/L) in 10.7%, and hypernatremia(Na>145mEq/L) in 11.2%. These results imply that the prehospital emergency care system useful at the scene of accident and during the transportation is more important than the simple quick-transport-system.

We report a case of cerebral lymphomatoid granulomatosis in a 50-year-old man. Lymphomatoid granulomatosis is an unusual condition which usually presents as a pulmonary manifestation, which occasionally affects the brain, and causes focal inflammatory lesions. Primary cerebral lymphomatoid granulomatosis is very rare. We describe a case of lymphomatoid granulomatosis in the left frontal lobe without pulmonary involvement.

For the evaluation of the 51Cr labelled in-vivo crossmatching test as a transfusion safety test, We examined the viability of the thransfused autologous and heterologous 51Cr labelled red cell at 1 hour and 24 hour in 6 normal volunteers and 4 patients whose RBC had been stored in CPDA-1 media from 1 day to 30 day. In both autologous transfusion control group(n=3) and allogeneic transfusion control group(n=3), the in-vivo RBC survival rate were more than 70% at 1 hour and 24 hour compared to that of basal 3 minute result(percent counted as 100%), and the eluted free radioisotope activity was less than 5% compared to that of whole blood. The crossmatch incompatible patient group also satisfied the safe transfusion criteria. The mean labelling efficiency which was tested in three patients was more than 95% and also satisfactory to reliable test. We concluded that in-vivo crossmatching test using 51Cr radioisotope would give us valuable informations about transfusion safety, especially in serologically incompatible patients.

The hypotensive effect of tripamide(Normonal(R)) were evaluated in 31 cases of essential hypertension. Fifteen to thirty mg of tripamide per day were administered continuously for 8 weeks. The results were as follows; 1) The systolic blood pressure was significantly lowered from 175+/-15 mmHg(Mean+/-SD) before treatment to 144+/-17 mmHg after treatment(p<0.01), and the diastolic blood pressure was significantly lowered from 106+/-11 mmHg before treatment to 90+/-12 mmHg after treatment(p<0.01). 2) The systolic blood pressure was lowered 20 mmHg or more in 25 out of 31 cases(80.7%), and the diastolic blood pressure was decreased 10 mmHg or more in 25 out of 31 cases(80.7%) at the end of 8 weeks treatement. 3) There was no significantl differences in the level of SGOT, serum cholesterol, serum electrolytes(Na+, K+, Cl-), BUN, creatinine and urinc acid before and after treatment with tripamide. 4) In most cases the subjective symptoms disappeared or became easier after tripamide treatment. 5) Profound weakness was developed in 2 cases during tripamide administration.

A case of puerperal cerebral hemorrhagic infarction with venous thrombosis in a 36-year-old female is reported. Brain CT scan showed an isodensity area surrounded by ill-defind low density medially in the right frontal lobe, and the most anterior portion of superior sagittal sinus and its draining veins were prominent, but draining veins in the frontal high convexity were not filled in the venous phase of the right carotid angiogram. Osteoplastic craniotomy on the right frontal area was performed to remove the lesion which was mistakenly understood as a mass. Abnormal brain parenchyma was excised from the right frontal subcortical region. Microscopic and pathological evaluation confirmed the diagnosis of hemorrhagic infarction due to venous thrombosis.

7.A Case of Transcatheter Coil Embolization of Diffuse Pulmonary Arteriovenous Malformation.
Journal of the Korean Pediatric Society 2001;44(9):1036-1040
This is a case report of multiple coil embolization for the diffuse pulmonary arteriovenous malformations(PAVM). PAVMs are direct communications between pulmonary arteries and pulmonary veins, resulting in an anatomic right-to-left shunt that may cause paradoxical embolization to may occur, resulting in neurologic complications such as stroke or cerebral abscess. The treatment of choice for solitary PAVMs was limited to surgical resection or ligation of the PAVM but, multiple PAVMs present a difficult management problem, since surgical resection is not feasible in most instances. The coil embolization is a safe and effective treatment of multiple PAVMs. Our exprience was of a 5-year-old boy who had cyanosis and clubbing of his finger, and was diagnosed with multiple PAVMs by chest CT and pulmonary angiography. The coil embolization was peformed, thirteen vessels were successfully occluded and no complication in placement of coils occured. Embolization therapy should be performed in all cases of PAVMs to prevent neurologic complications.

Journal of Korean Neurosurgical Society 1983;12(3):353-362
Ninety-three patients who had evidence of intraventricular hemorrhage(IVH) were reviewed. Primary and secondary IVH could be well distinguished by computerized tomographic(CT) brain scan. 11 patients had primary pure IVH and remaining 82 patients were secondary IVH from mainly hypertensive intracerebral hemorrhage. Four patients died and 7 survived in the pure IVH. Three of the 4 who died were aneurysmal rupture. Remaining one was unknown etiology. In CT scan hemorrhage was most frequently found in the occipital horns according to the supine position of the patient during the examination and least found in the temporal horns probably due to narrow crescentic shape. In the secondary IVH the distribution of the blood within the lateral ventricle was mainly ipslateral to the intracerebral hematoma. The point of penetration of the intracerebral hematoma into the lateral ventricle was the posterior body in the basal ganglia or thalamic hemorrhage, the frontal horn in the aneurysmal rupture and the trigone in the arteriovenous malformation. Although the level of consciousness on admission related to the size and location of primary intracerebral hemorrhage or IVH, the ventricular dilatation itself also seemed to contribute to the consciousness state. The degree of temporal horn dilatation correlated more with the clinical grade than the frontal horn dilatation.

9.Prevalence and Predictors of Exclusive Breastfeeding in Late Preterm Infants at 12 Weeks.
Child Health Nursing Research 2016;22(2):79-86
PURPOSE: The purpose of this study was to identify breastfeeding practice with late preterm infants (LPIs), and to determine predictors of exclusive breastfeeding at the 12th week after discharge. METHODS: The participants were 106 mothers of LPIs hospitalized in neonatal intensive care units at two university hospitals. Data were collected between February and October, 2013. Questionnaires included characteristics of LPIs, their mothers, and feeding-related characteristics. Feeding methods were exclusive breastfeeding, mixed feeding, and formula feeding. RESULTS: Exclusive breastfeeding steadily increased from 5.7% at the 1st week to 19.8% at the 12th week, as did formula feeding from 27.3% to 67.9%. Contrarily, mixed feeding decreased from 67.0% at the 1st week to 12.3% at the 12th week. The ratio of formula feeding was higher than that of exclusive breastfeeding over time. Predictors for exclusive breastfeeding were the following: type of delivery (OR=2.96, 95%CI=1.07-8.14), feeding intolerance (OR=3.03, 95%CI=1.26-7.25) and feeding method during hospitalization (OR=7.84, 95%CI=3.15-19.53). CONCLUSION: In order to increase breastfeeding opportunities for LPIs, educational programs for gestational age-appropriate breastfeeding should be developed. The focus of breastfeeding education needs to be on mothers who delivered their LPIs through Cesarean-section and LPIs who had feeding intolerance or were fed only formula during hospitalization.

A rare case of primary reticulum cell sarcoma(microglioma) of the brain in a 30-year-old female is reported. The tumor was located in the left parietal lobe. Brain CT scan showed a slightly high attenuated area with well demarcation in the left parietal lobe, and a tumor staining was appeared in the delayed arterial phase of the left carotid angiogram. Osteoplastic craniotomy on the left parietal area was performed for removal of tumor. Then the patient received radiation therapy with a good result.
