Objective: The prolactinoma is the most common pituitary tumor and sometimes shows severe invasiveness to the adjacent cavernous sinus, especially in the male patient. The dopamine agonist can be used as an alternative treatment modality to surgery. But, the transsphenoidal or transcranial approach for tumor removal has been more preferred treatment option of neurosurgeons in invasive prolactinoma. Especially rapid decompression of mass effect and resolution of the neurologic deficit is demanded. The prospective study is done in order to identify the therapeutic efficacy of bromocriptine as an initial treatment option for the invasive prolactionomas. Methods: Twenty patients with invasive prolactinoma were studied. Preoperative neurological and endocrinological evaluations were done, and size and invasiveness of the tumor was estimated on MRI. Bromocriptine was administrated by increasing dose planning reaching maximum dose at 1 month of treatment, with close neurological and endocrinological monitoring. At 3months after treatment, MRI was taken and decision was made whether to continue bromocriptine or to have surgical intervention. Results: Thirteen patients showed excellent result with only bromocriptine treatment. These patients showed not only marked reduction of tumor volume and prolactin level, but also, improving clinical symptoms and other hormonal deficits. 13patients who had visual field defect and decreased visual acuity had all improved visual symptoms. But, the remaining 4patients required surgical treatment due to insufficient reduction of tumor size inspite of normalized prolactin level within 3months. Remaining 2patients had $20{\sim}30%$ of tumor size reduction, but prolactin level was not normalized. One patient required radiation therapy. Conclusion: Bromociptine can be used as initial treatment for the invasive prolactinomas with careful monitoring of the neurological and endocrinological status. It should be carefully followed up for tumor size reduction within 3 months after initiation of treatment.

This study is a case report of Korean medicine treatment for a patient with quadriplegia and impaired cognition as neurological sequelae after ingestion of herbicides. A 59-year-old man with toxic encephalopathy and hypoxic encephalopathy after the ingestion of herbicides was treated with acupuncture, Hyulbuchuko-tang mixed with Ondam-tang-gami (血府逐瘀湯合溫膽湯加味), cupping, moxibustion, and rehabilitation. Clinical symptoms were measured with the Manual Muscle Test (MMT), Korean Mini Mental Status Exam (K-MMSE), Functional Independence Measure (FIM), and Modified Barthel Index (MBI). After three months of treatment, clinical symptoms improved. The motor function improved (MMT on both sides, Gr. 3+F/4G→Gr. 4-G~4G/4+G), cognition improved (K-MMSE, 13→21), and ADL (Activities of Daily Living) scores also improved (FIM 41→74; MBI 20→63). Korean medical treatment could effectively treat neurological sequelae after ingestion of herbicides in this case.

Objective : The authors reviewed 51 patients of spinal cord tumor located at the craniovertebral junction and high cervical area to determine which factors influenced resectability, complications, and postoperative outcomes. Methods : Radiological examinations, clinical data, and operation notes were evaluated, and additional follow-up information was obtained from outpatient examinations. The mean follow-up period was 3.5 years Results : The most common neurological findings were motor deficit(72.5%) and sensory change(47.1%). There was no clinical finding that is considered as pathognomic. Meningioma(18 cases, 35.3%) was the most common tumor in this region. Total removal was achieved in 45 patients. There was no surgical mortality. Immediate postoperative motor weakness were encounted in 11 cases(21.6%) which improved in long term followup except two patients. Conclusions : The location and relationship of the tumor to surrounding struncture determine its resectability. Postoperative results were related to the preoperative neurological status and pathological findings.

Objective : The goal of treatment for spinal cord ependymoma is complete removal without postoperative neurological deficit. The authors analyzed the surgical results and factors influencing the postoperative prognosis. Methods : Fifty-one cases of primary spinal cord ependymoma, surgically treated between 1979 and 2003, were retrospectively analyzed. The mean follow-up period was 44 months. Results : Gross total removal was achieved in 42 patients and incomplete removal in nine. The proportion of complete surgical removals was influenced by tumor location and histology. Disease progression was observed in five cases [9.8%], the mean progression free interval after surgical removal was 48 months and the 5-year progression free rate was 68%. Disease progression was found in none of the 42 cases who underwent complete removal, and in 5 of 9 cases who hadincomplete removal group [P<0.001]. Statistically significant disease-progression factors by multivariate analysis were the surgical extent of removal [P=0.012]. preoperative functional status [P=0.032] the presence of intratumoral cysts [P=0.007] and postoperative radiation therapy [P=0042]. Of those patients who underwent incomplete removal, radiation therapy was found to significantly improve the clinical result [P=0042]. Conclusion : In the surgical treatment of spinal cord ependymoma, preoperative functional status, the presence of intratumoral cysts, the extent of removal, and postoperative radiation therapy were found to be significant prognostic factors of postoperative outcome.

Objective: The evidence that hyperbaric oxygen (HBO) therapy is more effective for improving the acute neuropsychological status (ANS) of carbon monoxide poisoning than normobaric oxygen (NBO) therapy is not convincing. This is because the levels of carboxyhemoglobin (COHb) do not correlate with the clinical severity of carbon monoxide poisoning and there is no universally accepted severity scale of carbon monoxide poisoning. This paper suggests a new scale for the clinical and neurological severity of carbon monoxide poisoning, called the ANS, and assesses the effect of HBO therapy for each level of ANS compared to NBO therapy. Methods: A total of 217 patients who had been hospitalized because of carbon monoxide poisoning from January 2009 to July 2013 were studied. ANS was suggested as a new severity scale of carbon monoxide poisoning considered in the Glasgow Coma Scale, acute neuro-psychologic signs and symptoms, or cardiac ischemia on the initial medical contact. HBO therapy is indicated in those who have a loss of consciousness, seizure, coma, abnormal findings on a neurological examination, pregnancy, persistent cardiac ischemia, level of COHb >25%, or severe metabolic acidosis (pH <7.2). The end point is the day of discharge, and recovery is defined as a normal neuro-psychological status without any sequelae. Results: The levels of troponin T and creatinine increased significantly with increasing ANS score. In the moderate to severe group (ANS 2 and 3), the recovery rate was significantly higher when treated with HBO therapy than with NBO therapy (P=0.030). On the other hand, the development of delayed neuro-psychological sequelae (DNS) did not correlate with any level of ANS, type of oxygen therapy, or recovery on discharge. Conclusion: In the moderate to severe poisoned group, HBO therapy is more effective for improving the ANS from carbon monoxide poisoning than NBO therapy. On the other hand, the development of DNS of HBO therapy is no more preventable than with NBO therapy. Although the level of ANS is low, the patient needs to be provided with sufficient information and a follow-up visit is recommended for any abnormal symptoms because the ANS does not correlate with the development and degree of DNS.

Objective : The fate of partially thrombosed intracranial aneurysms (PTIAs) is not well known after endovascular treatment. The authors aimed to analyze the treatment outcomes of PTIAs. Methods : We retrospectively reviewed the medical records of 27 PTIAs treated with endovascular intervention between January 1999 and March 2018. Twenty-one aneurysms were treated with intraluminal embolization (ILE), and six were treated with parent artery occlusion (PAO) with or without bypass surgery. Radiological results, clinical outcomes and risk factors for major recurrence were assessed. Results : The initial clinical status was similar in both groups; however, the last status was better in the ILE group than in the PAO group (p=0.049). Neurological deterioration resulted from mass effect in one case and rupture in one after ILE, and mass effect in two and perforator infarction in one after PAO. Twenty cases (94.2%) in the ILE group initially achieved complete occlusion or residual neck status. However, 13 cases (61.9%) showed major recurrence, the major causes of which included coil migration or compaction. Seven cases (33.3%) ultimately achieved residual sac status after repeat treatment. In the PAO group, all initially showed complete occlusion or a residual neck, and just one case ultimately had a residual sac. Two cases showed major recurrence, the cause of which was incomplete PAO. Aneurysm wall calcification was the only significantly protective factor against major recurrence (odds ratio, 36.12; 95% confidence interval, 1.85 to 705.18; p=0.018). Conclusion : Complete PAO of PTIAs is the best option if treatment-related complications can be minimized. Simple fluoroscopy is a useful imaging modality because of the recurrence pattern.

Objectives: This study was aimed to review the global status of adverse event (AE) reports and the characteristics of the reported AEs of plants managed as herbal medicines (HMs) with toxic precautions in Korea. Methods: This is a cross-sectional quantitative study that analyzed information available through VigiAccess, a website that provides summarized statistical information from the WHO's global AE database to the public. VigiAccess was searched in 8 Jan, 2024. Information on the total number of reports, number of reports by year and continent, and the age and gender of patients were obtained, and the types of frequently reported AEs were also reviewed. Results: Data on the status of report submissions were obtained for a total of 9 HMs including Aconitum ciliare, Aconitum carmichaeli, Arisaema japonicum, Pinellia ternata, Euphorbiae Lathyridis, Croton tiglium, Strychni Ignatii, Strychnons nux-vomica, and Linum usitatissimum. The number of reports per HM was from 1 to 137. The most commonly reported type of AEs were gastrointestinal disorders in most of the HMs, followed by neurological disorders. Serious adverse events were reported only in Strychni Ignatii, Strychnons nux-vomica, and Linum usitatissimum, including one case of death. Conclusions: This study shows the status of reported AEs of botanicals considered as HMs with toxic precautions in Korea based on real world data. However, when interpreting the findings of this study, readers should consider the significant limitations of this study mainly because of the characteristics of the data source.

Aspirin (acetylsalicylic acid) is one of the most widely used therapeutic agents based on its pharmacological actions, including anti-inflammatory, analgesic, anti-pyretic, and anti-thrombotic effects. In this study, we investigated the effects of aspirin on seizure susceptibility and hippocampal neuropathology following pilocarpine-induced status epilepticus (SE). SE was induced by pilocarpine hydrochloride (280 mg/kg, i.p.) administration in C57BL/6 mice (aged 8 weeks). Aspirin was administered daily (15 mg/kg or 150 mg/kg, i.p.) for 10 days starting 3 days before SE, continuing until 6 days after SE. After pilocarpine injection, SE onset time and mortality were recorded. Neuronal cell death was examined using cresyl violet and Fluoro-Jade staining, and glial responses were observed 7 days post SE using immunohistochemistry. In the aspirin-treated group, the onset time of SE was significantly shortened and mortality was markedly increased compared to the control group. However, in this study, aspirin treatment did not affect SE-induced neuronal cell death or astroglial and microglial responses in the hippocampus. In conclusion, these results suggest that the safety of aspirin should be reevaluated in some patients, especially with neurological disorders such as temporal lobe epilepsy.

Japanese encephalitis is the leading cause of viral encephalitis in Asia, where it accounts for up to 50,000 cases. Approximately 20% of affected patients die, and 30-50% of survivors have significant neurological sequelae. Inactivated mouse-brain derived Japanese encephalitis vaccines has been effectively implemented to control the disease effectively in Korea and several other Asian countries. However, the vaccine is expensive and difficult to produce, requires multiple doses, and has been associated with hypersensitivity reactions and rare adverse neurologicale events. The live-attenuated SA14-14-2 vaccine derived from primary hamster kidney (PHK) cells was developed in China and has been used there since 1988. Outside China, it has been licensed and used in Korea and several other Asian countries. This vaccine is effective and inexpensive. However, the lack of precedence for using a PHK cell substrate in a live-attenuated vaccine is a special issue of concern. The WHO working group has recommended additional safety studies in selected high-risk groups, as well as ongoing post-marketing studies to ensure long-term safety. Recently, a new inactivated vaccine and live-attenuated chimeric vaccine have been developed from vero cells. With this background, this article summarized the current status of Japanese encephalitis vaccination worldwide and in Korea.

An excessive Q-angle has been implicated in the development of knee injuries by altering the lower-extremity locomotion kinematics. The purpose of this study was performed to examine the correlation between the Q-angle and the CTA during pronation and supination of the foot in the standing status. The participants of this examination were 60 adult(30 men and 30 women) who had no orthopaedic and neurological impairment, aged between 20 and 40years. The foot tilt(FT1)is made of acrylic plate and the slope of the surface is altered as $0^{\circ}$ pronation$(10^{\circ},\;20^{\circ},\;30^{\circ})$ and supination $(10^{\circ},\;20^{\circ},\;30^{\circ})$. The results were as follows : 1. The result about the Q-angle and the CTA by comparing pronation and supination of the foot There was statistical significance difference in the left /right Q-angle and the left/right CTA with pronation and supination of the foot(P<0.05). 2. The result about correlation in the left /right lower-extremity There were positive correlation between the right Q-angle and the right CTA and negative correlation except the supination$(30^{\circ})$ between the left Q-angle and the left CTA.
