Objectives: This study aimed to investigate the sociodemographic factors of stroke patients.Methods: Patients were hospitalized at Korean medical hospitals with cerebral hemorrhage and infarction and then discharged between September 2013 and August 2014. We investigated the patients’ general character and risk factors, then the patients were classified according to the regions where they reside.Results: The results indicated that having hypertension and diabetes mellitus as an underlying disease was more common in stroke patients from the country. No other statistical significance was noted among the indexes of any other results.Conclusions: Based on these results, hypertension, and diabetes mellitus were more important risk factors in patients from the country than they were for city residents. Further large-scale studies are needed to generalize the findings of this study.

Sam-Hwang-Sa-Shim-Tang(SHSST), a traditional Chinese medicine, composed of Rhei rhizoma, Scutellaria radix, and Coptidis rhizoma were used in the several disease including hypertension, constipation, and hemorrhage. In the present study, we investigated the neuroprotective effects of SHSST and its ingredients on the ischemia/ reperfusion-induced brain injury was evaluated in the rat brain. Ischemia was induced by intraluminal occlusion of the right middle cerebral artery for 120 min and reperfusion was continued for 22 h. SHSST (450 mg/kg), Rhei rhii oma (100 mg/kg), Coptidis rhizoma (100 mg/kg), and Scutellaria radik (100 mg/kg) were orally administered twice, promptly prior to reperfusion and 2 h after the repefusion. Total infarction volume in the ipsilateral hemisphere of ischemia/ reperfusion rats was significantly lowed by the treatments of SHSST (39.2%) and Scutellaria radix (66.5%). However, Coptidis rhizoma did not show any significant effects on the total infarct volume. The inhibiting effect of Scutellaria radix on the total infarct volume was more potent than that of SHSST. In addition, Scutellaria radix significantly inhibited myeloperoxidase (MPO) activity, an index of neutrophil infiltration in ischemic brain tissue. However, there was marked mismatch between total infarct volume and MPO activity in the Scutellaria radix-treated rats. Our findings suggest that Scutellaria radix as an ingredient of SHSST plays a protective role in ischemia-induced brain injury by inhibiting neutrophil infiltration. The effects of Rhei rhizoma on transient brain ischemia-induced neuronal injury are under study.

Background One of the main concerns in orbital blowout fracture repair is a narrow operation field, due mainly to the innate complex three dimensions of the orbit; however, a deep location and extensive area of the fracture and soft tissue edema can also cause concern. Swelling of the orbital contents progresses as the operation continues. Mannitol has been used empirically in glaucoma, cerebral hemorrhage, and orbital compartment syndrome for decompression. The authors adopted mannitol for the control of intraorbital edema and pressure in orbital blowout fracture repair. Methods This prospective study included 108 consecutive patients who were treated for a pure blowout fracture from January 2007 to October 2012. For group I, mannitol was administered during the operation. Under general anesthesia, all patients underwent surgery by open reduction and insertion of an absorbable mesh implant. The authors compared postoperative complications, the reoperation rate, operation time, and surgical field improvement between the two groups. Results In patients who received intraoperative administration of mannitol, the reoperation rate and operation time were decreased; however, the difference was not statistically significant. The total postoperative complication rates did not differ. Panel assessment for the intraoperative surgical field video recordings showed significantly improved vision in group I. Conclusions For six years, mannitol proved itself an effective, reliable, and safe adjunctive drug in the repair of orbital blowout fractures. With its rapid onset and short duration of action, mannitol could be one of the best methods for obtaining a wider surgical field in blowout fracture defects.

Purpose: This study aimed to find any difference in the clinical or the anatomical findings of vertebral artery dissection (VAD) between the trauma and the non-trauma groups. Methods: We retrospectively reviewed the clinical data and radiologic images of VAD patients. We compared data on symptoms, neurologic deficit, National institutes of health stroke scale (NIHSS) at admission, Rankin score (RS) at admission and discharge, and radiological findings including anatomical features, between the trauma and the non-trauma groups. Results: From January 1997 to May 2006, 42 patients were enrolled and 13 patients (31%) had a history of earlier trauma. Focal neurologic deficit (trauma group 11/13 vs. non-trauma group 11/29), cerebral stroke (10/13 vs. 9/29), and extradural lesions of dissection (6/13 vs. 3/28) were more common in the trauma group than non-trauma group (p=0.007, p=0.017, p=0.018, respectively) and NIHSS at admission and discharge were significantly higher (p=0.012, p=0.001, respectively). Dissecting aneurysms were less frequent in the trauma group (2/13 vs. 19/29, p=0.006). Subarachnoid hemorrhage and unfavorable prognostic value (Rankin score at discharge ${\geq}$ 2) showed no differences between the groups (p=0.540, p=0.267, respectively). Conclusion: In VAD patients after trauma, focal neurologic deficit due to ischemic stroke and a steno-occlusive pattern are more frequent than they are in non-trauma patients. The location of dissection was most frequent at the extradural vertebral artery in the trauma group. NIHSS was higher in the trauma groups but the incidence of an unfavorable prognostic value (RS ${\geq}$ 2) was not significantly different between the groups.

A total of 420 pyrolytic carbon mechanical valves were implanted in 336 patients from January, 1984, through Jung, 1988. Of the valves implanted, 131 were Bjork-Shiley, 250 St-Jude, and 39 Duromedics. The cumulative follow-up was 398 patient-years with a mean follow-up of 14.4 months per patients. Among 336 patients, 175 had mitral, 68 aortic, 82 multiple, 10 tricuspid, and one pulmonary valve replacement. The hospital mortality figures were 9 of 336[2.67%] in all, 5 of 175[2.85%] in isolated mitral, 1 of 68[1.47%] in isolated aortic and 3 of 82[3.65%] in multiple valve replacement. The causes of hospital mortality were myocardial failure in 5, sepsis in 2, bleeding in 1, cerebral embolism in l. There was no late valve related mortality. The actuarial survival rate at 4.5years was 99.4*0.1%. The complications occurred in 15 of 336[4.46%]; 7 of 175[4.0%] in isolated mitral, 4 of 68[5.88%] in isolated aortic, and 4 of 82[4.89%] in multiple valve replacement. The causes of complications were thromboembolism in 4, hemorrhage in 4, paravalvular leakage in 4, hepatitis in 2, and complete AV block in l. Actuarial probability of survival at 4.5 years was 95.0*0.1%. The low mortality and complications encourage us to applicate these valves to any patient including children and young women.

The source of prescription of Jihwangeumja to treat the mental confusion due to phlegm caused by kidney 'deficiency and Yin and Yang deficiency is found in 'Hwangjesomunseonmyeongronbang $\ll$黃帝素問宣明論方$\gg$'. The source of prescription of Jihwangeum is found in 'Seongjechongnok $\ll$聖濟總錄$\gg$'. Therefore, it seems reasonable to change the prescription to 'Jihwangeum' from 'Jihwangeumja' and to change the source of prescription to 'Seongjechongnok $\ll$聖濟總錄$\gg$' from 'Hwangjesomunseonmyeongronbang $\ll$黃帝素問宣明論方$\gg$'. In addition, 'Jihwangeum' is influenced by 'Naebosan' in 'Cheongeumbang $\ll$千金方$\gg$'. Jihwangeumja gave the substantial influence on the treatment of 'Endogenous wind due to hyperactivity' of Yeopcheonsa. Jihwangeumja supplements the true Yuan, smooths the circulation of the flow inside a body and coordinates the interaction between heart and kidney so that it ultimately eliminates sputum and activates circulation inside a body. If the guideline of diagnosis is accurate, many kinds of diseases can be effectively treated through the principle of treating different disease with the same therapy. In addition, it will be also effectively used for headache after cerebral hemorrhage, trigeminal neuralgia(sore tongue), diabetes insipidus, nervous breakdown, hyperthyroidism, chronic glomerulonephritis, infertility and anemia.

Korea currently has the world's lowest birth rate but a rapidly inreasing number of preterm infants. The Korean Neonatal Network (KNN), launched by the Korean Society of Neonatology under the support of Korea Centers for Disease Control, has collected population-based data for very low birth weight infants (VLBWIs) born in Korea since 2013. In terms of the short-term outcomes of VLBWIs born from 2013 to 2016 registered in the KNN, the survival rate of all VLBWIs was 86%. Respiratory distress syndrome and bronchopulmonary dysplasia were observed in 78% and 30% of all VLBWIs, respectively. Necrotizing enterocolitis occurred in 7%, while 8% of the VLBWIs needed therapy for retinopathy of prematurity in the neonatal intensive care unit (NICU). Sepsis occurred in 21% during their NICU stay. Intraventricular hemorrhage (grade ≥III) was diagnosed in 10%. In terms of the long-term outcomes for VLBWIs born from 2013 to 2014 registered in the KNN, the post-discharge mortality rate was approximately 1.2%-1.5%, mainly owing to their underlying illness. Nearly half of the VLBWIs were readmitted to the hospital at least once in their first 1-2 years of life, mostly as a result of respiratory diseases. The overall prevalence of cerebral palsy was 6.2%-6.6% in Korea. Bilateral blindness was reported in 0.2%-0.3% of VLBWIs, while bilateral hearing loss was found in 0.8%-1.9%. Since its establishment, the KNN has published annual reports and papers that facilitate the improvement of VLBWI outcome and the formulation of essential healthcare policies in Korea.

Objective : Mechanical thrombectomy (MT) for acute intracranial internal carotid artery (ICA) occlusion is often complicated by difficult revascularization and non-involved territory embolization possibly related with larger clot-burden. This study aims to evaluate the efficacy of proximal aspiration thrombectomy (PAT) using a balloon-tipped guide catheter for clot-burden reduction in such cases with period-to-period analysis (period 1 : standard MT without PAT; period 2 : PAT first, then standard MT for the remaining occlusion). Methods : Eighty-six patients who underwent MT for acute intracranial ICA occlusion were included in this analysis from the prospectively maintained stroke registry (33 patients in period 1 and 53 in period 2). In period 2, 'responder' was defined as a case where some amount of clot was retrieved by PAT and the following angiography showed partial or full recanalization. Results : Fifteen of fifty-three patients in period 2 (28.3%) were 'responders' to PAT. There was a significantly higher incidence of atrial fibrillation in the 'responder' subgroup. Period 2 showed a significantly shorter puncture-to-reperfusion time (94.5 minutes vs. 56.0 minutes; p=0.002), a significantly higher Thrombolysis in Cerebral Infarction of 2b-3 reperfusion (45.5% vs. 73.6%; p=0.009), but only a trend for better 3-month favorable outcome (mRS 0-2; 36.4% vs. 54.7%; p=0.097). There was no increase in the incidence of procedure-related complications or intracranial hemorrhage in period 2. Conclusion : A strategy of PAT before standard MT may result in shorter puncture-to-reperfusion time and better angiographic outcome than a strategy of standard MT for acute intracranial ICA occlusion.

Objectives : The BangPungTongSungSan(BPTSS) has been used as a therapeutic agent for cerebrovascular disease, cerebral hemorrhage, hypertension, diabetes and obesity in oriental medicine. The present study designed to investigate the effect of BPTSS on behavioral change and neuronal activation induced by acute methamphetamine(METH, 2 mg/kg, i.p.) in C57BL/6 mice. Methods : Mice received the oral administration of BPTTS(25, 50 and 100 mg/kg) 1 h prior to saline or METH administration. Locomotor activity was measured for 90 min using videotractking method and c-Fos expression, as marker of neuronal activation, was identified in a separate groups of mice by immunohistochemistry. Results and conclusions : Methamphetamine injection significantly increased locomotor activity and c-Fos expression in the nucleus accumbens and striatum. Interestingly, BPTTS(100 mg/kg) significantly suppressed locomotor activity and c-Fos expression in the nucleus accumbens and striatum by acute exposure to METH. These results suggest that BangPungTongSungSan may be effective in suppressing the reinforcing effect of methamphetamine by modulation neuronal activity.

Primary mediastinal choriocarcinoma is characteristically seen in young males presenting with the symptomes of cough, chest pale, and gynccomastia. A 33-year-old woman was admitted to the hospital because of severe dyspnea and chest pain which was aggravated rapidly 2 or 3 days ago. Posterior mcdiastinal mass measuring about 1 cm in diameter was seen in Chest P-A, left lateral view of chest, and chest CT. Serum $\beta$-HCG level was markedly elevated up to 200, 000 mIxt. Whole body CT and other studies could not find any lesion on ovary and uterus. But, a single nodule nEeasuring about 1 cm in diameter was identified in the brain CT. The tumor cells (syncytiotrophoblastic cells) from resected mass revealed positivity on i histochemical staining for $\beta$-HCG. She was treated with EMA-CO after resection of tumor, But, 7 months later, she was readmitted and showed cerebral hemorrhage due to metastatic choriocarcinoma. She was operated again for the brain tumor, and was doing well for further 7 months.
