Acute motor and sensory axonal neuropathy (AMSAN) are recently described subtypes of Guillain-Barre syndrome characterized by acute onset of distal weakness, loss of deep tendon reflexes, and sensory symptoms. A 21-yr-old male was transferred to our hospital due to respiration difficulties and progressive weakness. In laboratory findings, immunoglobulin M antibodies against hepatitis A were detected in blood and cerebrospinal fluid. The findings of motor nerve conduction studies showed markedly reduced amplitudes of compound muscle action potentials in bilateral peroneal, and posterior tibial nerves, without evidence of demyelination. Based on clinical features, laboratory findings, and electrophysiologic investigation, the patient was diagnosed the AMSAN following acute hepatitis A viral infection. The patient was treated with intravenous immunoglobulin and recovered slowly. Clinicians should consider this rare but a serious case of AMSAN following acute hepatitis A infection.

This study was designed to evaluate the protective effect of Korean red ginseng (KRG) against ischemia/reperfusion (I/R) injury in isolated guinea pig heart. KRG has been shown to possess various ginsenosides, which are the major components of Panax ginseng. These components are known naturally occurring compounds with beneficial effects and free radical scavenging activity. The heart was induced to ischemia for 60 min, followed by 120 min reperfusion. The hearts were randomly allocated into five groups (n=8 for each group): normal control (N/C), KRG control, I/R control, 250 mg/kg KRG group and 500 mg/kg KRG group. KRG significantly increased hemodynamics parameters such as aortic flow, coronary flow and cardiac output. Moreover, KRG significantly increased left ventricular systolic pressure (LVSP), the maximal rate of contraction (+dP/dtmax) and maximal rate of relaxation (-dP/dtmax). Also, treatment of KRG ameliorated electrocardiographic index such as the QRS, QT and RR intervals. Moreover, KRG significantly suppressed the lactate dehydrogenase, creatine kinase-MB fraction and cardiac troponin I and ameliorated the oxidative stress markers such as malondialdehyde and glutathione. KRG was standardized through ultra performance liquid chromatograph analysis for its major ginsenosides. Taken together, KRG has been shown to prevent cardiac injury by normalizing the biochemical and oxidative stress.

We found that care management not only contributed to reducing depressive symptoms in geriatric patients suffering from depression but also increased the treatment adherence rate, which in turn increased the remission rate. Care management intervention is both feasible and effective in psychiatric clinics in Korea.

Thunderclap headache (TCH) refers to a sudden-onset, severe headache that features in subarachnoid hemorrhage, unruptured intracranial aneurysm, cerebral venous thrombosis, pituitary apoplexy, cervical artery dissection, and hypertensive reversible posterior leukoencephalopathy. TCH is a rare manifestation in cerebral or cerebellar infarctions. Herein, we report on a 60-year-old woman with a thunderclap headache as the first symptom of cerebellar infarction, in the absence of abnormal findings in the brain computed tomography (CT), CT angiography, and lumbar puncture. An urgent brain MRI showed an acute infarction of the right cerebellar hemisphere. The next day, the patient presented with right side ataxia. In emergency cases presenting with thunderclap headache, one should consider an expanded evaluation and/or close observation, with frequent neurological examinations, even though the findings are normal on the initial neurological examination, cerebrospinal fluid analysis, and brain CT.

Purpose: During oxidative stress, the levels of oxygen free radical increase dramatically, which plays a role in apoptosis, aging and is chemic injury, but also leads to positive effects such as induction of host defense genes and mobilization of ion transport systems. It has been suggested that the advantages of laparoscopic surgery are closely related to the reduced oxidative stress that occurs during laparoscopic cholecystectomy (LC) when compared to open cholecystectomy (OC). This study was conducted to compare oxidative stress markers including total antioxidant status (TAS), superoxide dismutase (SOD) and gluthathione reductase (GR) between the LC group and OC group to determine if these surgical procedures result in different patterns of oxidative stress.Methods: Our prospective study included fifty patients with symptomatic cholelithiasis and cholecystitis, of whom 25 underwent LC and 25 underwent OC. The plasma levels of oxidative stress markers (TAS, SOD, and GR) were measured preoperatively and on the 1st, 2nd and 3rd postoperative days.Results: The postoperative hospitalization days differed significantly between the two groups (p＜0.01). The value of TAS decreased in the OC group in the immediate postoperative period (p=0.037), but this difference was not significant when analyzed by ANCOVA (analysis of covariance; p＞0.05). An acceptable postoperative decrease in SOD was observed in the OC group, especially after the 2nd postoperative day (p＜0.01), and this decrease was also significant when analyzed by ANCOVA (p=0.020). GR was decreased in the OC group on
