Abstract
Jogaejeot, seasoned Venerupis philippinarum, is a traditional Korean fermented food, and hepatitis A virus (HAV) can be transmitted through contaminated food, especially bivalve shellfish, causing acute gastroenteritis worldwide. Here, we carried out a phylogenetic analysis to identify and characterize HAV strains in jogaejeot samples associated with hepatitis A (HA) outbreaks in Seoul, South Korea, in 2019. The HAV strains were identified using blast and molecular analysis of the amplified HAV VP1-P2B genome region. The HAV strains identified in the five jogaejeot samples shared at least 99% sequence identity, were all classified as genotype IA and were most closely related to strains that are widespread in East Asia. These results support a link between the consumption of jogaejeot and the HA outbreaks observed in 2019 in Seoul. In addition, they indicate a need for more stringent enforcement of food safety regulations for the shellfish industry, especially against HAV, and the value of widespread vaccination.

Abstract
Objective Subarachnoid hemorrhage (SAH) caused by rupture of an internal carotid artery (ICA) or vertebral artery (VA) dissecting aneuryesm is rare. Various treatment strategies have been used for ruptured intracranial dissections. The purpose of this study is to compare the clinical and angiographic characteristics and outcomes of endovascular treatment for ruptured dissecting aneurysms of the intracranial ICA and VA. Methods The authors retrospectively reviewed a series of patients with SAH caused by ruptured intracranial ICA and VA dissecting aneurysms from March 2009 to April 2014. The relevant demographic and angiographic data were collected, categorized and analyzed with respect to the outcome. Results Fifteen patients were identified (6 ICAs and 9 VAs). The percentage of patients showing unfavorable initial clinical condition and a history of hypertension was higher in the VA group. The initial aneurysm detection rate and the percentage of fusiform aneurysms were higher in the VA group. In the ICA group, all patients were treated with double stent-assisted coiling, and showed favorable outcomes. In the VA group, 2 patients were treated with double stent-assisted coiling and 7 with endovascular trapping. Two patients died and 1 patient developed severe disability. Conclusion Clinically, grave initial clinical condition and hypertension were more frequent in the VA group. Angiographically, bleb-like aneurysms were more frequent in the ICA group and fusiform aneurysms were more frequent in the VA group. Endovascular treatment of these aneurysms is feasible and the result is acceptable in most instances.

Abstract
Objective Chronic subdural hematoma (CSDH) is common in elderly patients. So, with an increasing number of elderly people in the general population, there is a need to investigate risk factors which increase recurrence rate. In this study, factors affecting the postoperative recurrence are investigated based on the reoperative CSDH cases. Methods Total of ninety-seven patients was enrolled in this study who had have operation for CSDH. In all patients, one burr hole trephination and drainage was the method of choice for the initial treatment of CSDH. We retrospectively evaluated several factors which affect to recurrence of CSDH. Results Retrospective analysis was performed in 97 patients. Sixteen patients experienced reoperation within 3 months (16/97, 16.5%) for recurrence of CSDH. And, when hematoma was divided by internal architecture, heterogeneous density group seems to be have close relationship with recurrence more significantly than homogeneous density group (p=0.002). Hypertension, diabetes mellitus, early removal of drainage tube, bilaterality of hematoma also have significant relationship with recurrence. Conclusion Recurrence rate of CSDH treated with one burr hole drainage is related with some various factors. There was statistically significant difference between recurred group and non-recurred group. Not only demographic factors but also internal architecture on preoperative brain computed tomography is a significant predicting factor of recurrence in CSDH patients who underwent a surgery. In this study, heterogeneous type hematoma have significantly related with recurrence of CSDH. We should give attention to these predicting factors for more effective care.

Abstract
OBJECTIVES To introduce a more effective surgical technique for the repair of spontaneous incurable cerebrospinal fluid (CSF) leakage (CSF otorrhea). METHODS The cases of five Chinese patients with Mondini dysplasia and CSF leakage were reviewed. All patients presented with rhinorrhea or otorrhea from childhood and recurrent meningitis attacks. CSF leakage was repaired surgically using the translabyrinthine approach. RESULTS Facial paralysis occurred in the first two patients, but was cured 2 months later. The other three patients recovered well and had no facial paralysis or complication. CSF leakage did not recur in any patient after follow-up periods of 0.5-3 years. CONCLUSION Mondini dysplasia with CSF leakage is rare. Adequate diagnosis and treatment are required to avoid life-threatening complications, such as meningitis. We recommend the translabyrinthine approach as an alternative surgical technique that reduces recurrence.

Abstract
CONCLUSIONS The diagnosis of occult otogenic cerebrospinal fluid (CSF) leakage is challenging and it can easily be misdiagnosed. Some characteristics of clinical presentation can supply important clues and confirmed diagnosis should be obtained according to these clues and suitable imaging studies before meningitis develops. Different surgical techniques should be adopted to treat the CSF leakage according to different leakage etiologies, and good results can be obtained. OBJECTIVE The aim of the study was to evaluate the diagnosis and surgical treatment of occult otogenic CSF leakage, including the characteristics of clinical presentation, imaging studies, and operation methods in order to decrease the rate of misdiagnosis and obtain a good curative effect. METHODS We performed a retrospective review of 11 cases of CSF leakage that were all misdiagnosed and accompanied by meningitis, operated in our department from 2007 to 2012 after a mean follow-up of 3 years. In this context, the characteristics of clinical presentation, imaging studies, and management of CSF leakage were studied. RESULTS The CSF leakage had arisen traumatically (n = 9) or congenitally (n = 2). The medical history and special clinical presentation such as repeated otorrhea or rhinorrhea, fever, headache, and unilateral deafness can supply important diagnostic clues. Imaging studies including high-resolution noncontrast CT (HRCT), CT cisternography, and magnetic resonance imaging (MRI) are very important diagnostic methods. The surgical repairs were performed via a transmastoid approach (n = 8), packing the vestibule (n = 1) or a translabyrithine approach (n = 2). Recurrent leakage did not occur.

Abstract
Stem cells have been highlighted for a possible clinical trial in amyotrophic lateral sclerosis (ALS), and have been employed in SOD1 mice and ALS patients. Human trials for stem cell transplantations have used intrathecal route by lumbar puncture. However, stem cells introduced via lumbar injection would tend to sink downwards rather than ascending to the brain and cervical and thoracic spinal cord. Therefore, we adopted for intraventricular injection via an Ommaya reservoir, and wished to test the practicality of intraventricular stem cell injection in ALS. In the case presented autologous mesenchymal stromal cells (MSCs) were isolated from the bone marrow of a male patient with ALS who underwent insertion of an Ommaya reservoir. Expanded MSCs (hBM-MSCs: dose of 1 X 106 cells/kg) were suspended in autologous CSF and directly transplanted into the ALS patient's lateral ventricle via the Ommaya reservoir. Clinical, laboratory, and radiographic evaluation of the patient revealed no serious adverse effects related to the stem cell therapy. Intraventricular injection with an optimized number of cells is safe, and is a potential route for stem cell therapy in patients with ALS. Intraventricular injection via an Ommaya reservoir makes repetitive injection of stem cells easy and reliable even in far advanced ALS patients.

Abstract
CONCLUSION Molecular margins were a more important prognostic factor in laryngeal carcinoma in Chinese patients than histopathological margins. eIF4E was the most sensitive molecular index of those that we tested for in these patients. OBJECTIVES Safe surgical margins are closely related to prognosis. The aim of the present study was to investigate the role of molecular margins, not traditional histopathological margins, as prognostic factors in laryngeal carcinoma in Chinese patients. An additional aim of the study was to investigate the prognostic significance of tumor markers in the primary site of laryngeal carcinoma. METHODS From January 1992 to January 2000, the data for 321 Chinese patients with laryngeal carcinoma who were divided into a recurrent laryngeal carcinoma group and a non-recurrent group were analyzed. Tumor markers in surgical margins and primary site, such as cyclin D1, p53, and eIF4E, were detected in the two groups with immunohistochemical staining. RESULTS There was a significant difference in the expression of cyclin D1, p53, and eIF4E in surgical margins between the recurrent laryngeal carcinoma group and the non-recurrent group. The eIF4E-positive rate in surgical margins was higher than that for the other two factors. There was a significant difference in cyclin D1 and p53 in the primary site of laryngeal carcinoma and no significant difference in eIF4E in the two groups.

Abstract
OBJECTIVE There are numerous reports on the primary stabilizing effects of the different cervical cages for cervical radiculopathy. But, little is known about the subsidence which may be clinical problem postoperatively. The goal of this study is to evaluate subsidence of cage and investigate the correlation between radiologic subsidence and clinical outcome. METHODS To assess possible subsidence, the authors investigated clinical and radiological results of the one-hundred patients who underwent anterior cervical fusion by using AMSLUtrade mark cage during the period between January 2003 and June 2005. Preoperative and postoperative lateral radiographs were measured for height of intervertebral disc space where cages were placed. Intervertebral disc space was measured by dividing the sum of anterior, posterior, and midpoint interbody distance by 3. Follow-up time was 6 to 12 months. Subsidence was defined as any change in at least one of our parameters of at least 3 mm. RESULTS Subsidence was found in 22 patients (22%). The mean value of subsidence was 2.21 mm, and mean subsidence rate was 22%. There were no cases of the clinical status deterioration during the follow-up period. No posterior or anterior migration was observed. CONCLUSION The phenomenon of subsidence is seen in substantial number of patients. Nevertheless, clinical and radiological results of the surgery were favorable. An excessive subsidence may result in hardware failure. Endplate preservation may enables us to control subsidence and reduce the number of complications.

Abstract
BACKGROUND AND PURPOSE Despite systemic heparinization, thromboembolic complications remain a major concern related to endovascular treatment of intracranial aneurysms. We assessed the safety of intravenous eptifibatide administered during aneurysm coiling procedures to prevent such complications. METHODS From August 2001 to November 2004, 298 coil embolization procedures were performed to treat intracranial aneurysms; eptifibatide was used in 84 endovascular coil embolization procedures to treat 79 aneurysms in 74 patients. We retrospectively reviewed medical charts, radiographic images, and procedure notes to evaluate periprocedural complications related to eptifibatide. RESULTS The mean age of the 74 patients in our cohort was 55 +/- 9 years (range, 31-84) harboring 79 aneurysms (32 ruptured/47 unruptured). Eptifibatide was given prophylactically in 77 procedures, whereas in 7 procedures, it was given for treatment of a thromboembolic event (visualization of an arterial branch occlusion). A total of 5 (5.9% [total cohort]) bleeding complications related to eptifibatide occurred during 84 procedures. Two patients (2.4% [total cohort]/6.3% [ruptured group]) developed intracerebral hemorrhagic complications exacerbated by eptifibatide. The other 3 (3.6% [total cohort]) patients had groin hematomas requiring blood transfusions but had no surgical intervention. One thromboembolic event occurred in the 77 patients receiving eptifibatide prophylactically. CONCLUSIONS Intravenous infusion of eptifibatide seems to be safe to administer in patients undergoing endovascular repair of an unruptured cerebral aneurysm. Caution must be used in patients harboring ruptured aneurysms as intracranial bleeding complications may occur. Further study is required to delineate the group of patients most likely to benefit from this therapy.

Abstract
Recently, it was reported that fenestration of the lamina terminalis (LT) may reduce the incidence of shunt-dependent hydrocephalus in aneurysmal subarachnoid hemorrhage (SAH). The authors investigated the efficacy of the LT opening on the incidence of shunt-dependent hydrocephalus in the ruptured anterior communicating artery (ACoA) aneurysms. The data of 71-ruptured ACoA aneurysm patients who underwent aneurysmal clipping in acute stage were reviewed retrospectively. Group I (n=36) included the patients with microsurgical fenestration of LT during surgery, Group II (n=35) consisted of patients in whom fenestration of LT was not feasible. The rate of shunt-dependent hydrocephalus was compared between two groups by logistic regression to control for confounding factors. Ventriculo-peritoneal shunts were performed after aneurysmal obliteration in 18 patients (25.4%). The conversion rates from acute hydrocephalus on admission to chronic hydrocephalus in each group were 29.6% (Group I) and 58.8% (Group II), respectively. However, there was no significant correlation between the microsurgical fenestration and the rate of occurrence of shunt-dependent hydrocephalus (p>0.05). Surgeons should carefully decide the concomitant use of LT fenestration during surgery for the ruptured ACoA aneurysms because of the microsurgical fenestration of LT can play a negative role in reducing the incidence of chronic hydrocephalus.

Abstract
Endovascular approaches can be utilized to manage arteriovenous fistulas (AVFs) either as a stand alone therapy or in conjunction with surgical excision. The goal of treatment is to completely obliterate the AVF. These vascular malformations are rare in childhood and pose a treatment challenge. We describe 3 children who were diagnosed with vascular malformations on magnetic resonance imaging and were subsequently found to have unusual AVFs on angiography. These single-feeder fistulas were successfully occluded with transarterial embolization using platinum coils.

Abstract
BACKGROUND Common peroneal nerve palsy is a well-recognized complication following orthopedic procedure in and around the knee region. In neurosurgical practice, however, this kind of injury with regard to the patients' position is seldom reported. CASE DESCRIPTION We describe an immediately developed common peroneal nerve palsy in a 53-year-old slender man who underwent anterior cervical operative procedure. He suffered incomplete common peroneal nerve injury for about 8 months and during this period, he underwent 2 electromyographic examinations suggesting demyelinating injury. He received conservative treatment including physiotherapy and rigid foot orthosis and finally made a favorable but incomplete recovery. CONCLUSION We propose that such palsy may result from immobilization in a certain position instead of direct compression or traction of the corresponding nerve, although this is not proven. In this report, we suggest the possible risk factors, preventive measures, therapeutic options, and relevant outcome of this unwanted result.

Abstract
A 41-year-old woman suffered fever, speech disturbance and confusion four months after transsphenoidal surgery for pituitary macroadenoma. Meanwhile, the patient had been well except for transient asymptomatic postoperative pneumocephalus without cerebrospinal fluid (CSF) rhinorrhoea. Brain computed tomographic scan revealed a peripherally enhancing pineal abscess which superimposed on a preexisting pineal cyst. CSF findings showed elevated leukocyte count and positive bacterial culture. Three weeks of intensive antibiotic therapy and surgical evacuation of the pineal abscess ensued. The patient showed restricted postoperative recovery with moderate hypothalamic dysfunction. A unique case of delayed-onset postoperative pineal abscess which complicates the preexisting asymptomatic pineal cyst is presented and the possible explanation for this is speculated with review of the available literatures.

Abstract
A rare case of intraventricular germinoma in the third ventricle, which occurred 30 months after total removal of mature teratoma on the same location in a 29- yr-old man is presented. Recurrence is supposed to represent an acceleration of localized dysplastic processes of totipotent germ cells present in the midline neuraxis or a growth of unidentified microscopic residue of germinoma component in mature teratoma. Although the radiation therapy after total removal of mature teratoma is still controversial, careful follow-up is warranted for evaluating a possible recurrence of other germ cell tumors.

Abstract
Some Korean women draw tattoo in their eyebrow to cover the scant hair. If a patient has a tattoo in her eyebrow, lesions of anterior cranial fossa can be easily managed with this small eyebrow skin incision through a small unilateral supraorbital craniotomy. By this technique, 7 cases of anterior cranial fossa lesions were successfully treated without any major complications. This leads to less facial scar, less operation time and an earlier return to social adaptation.

Abstract
Metastatic tumors in the sellar and parasellar regions are uncommon and rarely detected in clinical practice. We present four cases of sellar and parasellar metastatic tumors, which metastasized from distant organ in one case and extended directly from adjacent structures in three. Common presenting symptoms were cranial neuropathies, headache and facial pain. Invasion into the cavernous sinus was noted in all cases. We report rare cases of sellar and parasellar metastases. Also, we should consider the possibility of metastasis in these regions for patients who showed the above clinical presentations in systemic cancer patients. In extensive diseases, transient symptomatic relief could be obtained by direct surgical management, even in restricted degree.
