We report a rare case of Brown-Sequard syndrome associated with Horner's syndrome in cervical epidural hematoma caused by a ruptured arteriovenous malformation. A 54-year-old man developed sudden sharp neck pain, radiating to the interscapular area. Within hours, left side hemiplegia and decreased tactile sense and loss of contralateral pain sense ensued. Emergency cervical magnetic resonance image showed an epidural hematoma over the cervico-thoracic junction. The hematoma was located in the left posterolateral area of the cervical spinal canal. Emergent decompressive laminectomy and an evacuation of the hematoma were performed. A tangled soft tissue mass found in the hematoma was proven to be an arteriovenous malformation. To the authors, knowledge, this might be the first case of a Brown-Sequard syndrome associated with Horner's syndrome caused by ruptured cervical epidural arteriovenous malformation.

Purpose: Brown's syndrome is characterized by the limited elevation in adduction from mechanical causes around the superior oblique tendon trochlea complex. In this particular case, post-traumatic facial deformity accompanied by Brown's syndrome was observed. We would like to report the satisfying cosmetic results obtained by reconstructing orbital roof and superior orbital rim and repositioning of zygoma. Methods: A 12-year-old patient was observed with facial deformity with strabismus in her right eye and orbital dystopia after the car accident and was eventually diagnosed with traumatic Brown's syndrome. Reconstructive surgeries could not be performed at the time of trauma due to the cerebral hemorrhage. At the second year after the trauma, a depressed fracture of the right orbital roof and superior orbital rim were reconstructed via the intracranial approach, and orbital dystopia was corrected via the zygoma triple ostectomy. In addition, a strabismus surgery was performed one year after her plastic surgery. Results: Facial deformity with orbital dystopia and strabismus was confirmed to be fully reconstructed after the surgery. Moreover, when the patient came in for a follow-up thirteen years after the operation, a developmental imbalance of the facial bones, diplopia, or any other surgical complications were not to be found. Conclusion: After the trauma, the patient with Brown's Syndrome accompanied by post-traumatic facial deformity, who went under the corrective surgeries after the meticulous examination and assessment pre-surgically, was able to acquire cosmetic satisfaction via those operations.

The possible causes of Brown-S$\acute{e}$quard Syndrome (BSS) have been frequently observed with spinal trauma and extramedullary spinal tumors, but the cervical disc herniation to cause BSS is rare. The authors present five cases of patients who were diagnosed with BSS resulting from cervical disc herniation, and the results of the literature in view of their distinctive symptoms and clinical outcomes. Postoperatively, the patients showed complete or almost complete recovery from their motor and sensory deficits. On the basis of our cases, it is important to diagnose it early by cervical magnetic resonance imaging, especially in the absence of the typical symptoms of cervical disc herniation or other obvious etiology of extremity numbness. Immediate surgical treatment is also essential for a favorable functional neurological recovery.

Gorlin-Goltz syndrome, also known as nevoid basal cell carcinoma syndrome, is an autosomal dominant disease characterized by multisystemic developmental defects caused by pathogenic variants such as patched-1 (PTCH1) gene variants and/or SUFU gene variants. The presence of either two main criteria or one major and two minor criteria are required for the diagnosis of Gorlin-Goltz syndrome. Recently, a major criterion for molecular confirmation has also been proposed. In this article, we report the case of an 80-year-old male who was admitted at our department for multiple brown-to-black papules and plaques on the entire body. He was diagnosed with Gorlin-Goltz syndrome with clinical, radiologic, and pathologic findings. While the diagnosis was made based on the clinical findings in general, confirmation of the genetic variants makes an ideal diagnosis and suggests a new treatment method for target therapy. We requested a genetic test of PTCH1 to ideally identify the molecular confirmation in the hedgehog signaling pathway. However, no pathogenic variants were found in the coding region of PTCH1, and no molecular confirmation was achieved.

Spontaneous herniation of the spinal cord is a very rare. It's clinical symptom presents with progressive myelopathy. A 42-year old male patient who presented the progressive left leg weakness and Brown-Seqaurd syndrome is presented. MRI showed a typical finding of dural defect and herniation of the cord on the level of T3-4. Repair of dural defect using an artificial dura and reposition of cord herniation were undertaken after three level laminectomies with SSEP monitoring. Postoperatively, symptoms were improved rapidly. In our knowledgement, this is first case being reported in Korea. This entity, although rare, should be considered in the differential diagnosis of myelopathy in the absence of a mass lesion.

Human coronavirus diseases, particularly severe acute respiratory syndrome coronavirus 2, still remain a persistent public health issue, and many recent studies are focusing on the quest for new leads against coronaviruses. To contribute to this growing pool of knowledge and explore the available marine natural products against coronaviruses, this study investigated the antiviral effects of fucoxanthin isolated from Sargassum siliquastrum-a brown alga found on Jeju Island, South Korea. The antiviral effects of fucoxanthin were confirmed in severe acute respiratory syndrome coronavirus 2-infected Vero cells, and its structural characteristics were verified in silico using molecular docking and molecular dynamic simulations and in vitro colorimetric method. Fucoxanthin inhibited the infection in a concentration-dependent manner, without showing cytotoxicity. Molecular docking simulations revealed that fucoxanthin binds to the angiotensinconverting enzyme 2-spike protein (binding energy -318.306 kcal mol^-1) and main protease (binding energy -205.118 kcal mol^-1). Moreover, molecular dynamic simulations showed that fucoxanthin remains docked to angiotensin-converting enzyme 2-spike protein for 20 ns, whereas it breaks away from main protease after 3 ns. Also, the in silico prediction of the fucoxanthin was verified through the in vitro colorimetric method by inhibiting the binding between angiotensinconverting enzyme 2 and spike protein in a concentration-dependent manner. These results indicate that fucoxanthin exhibits antiviral effects against severe acute respiratory syndrome coronavirus 2 by blocking the entry of the virus. Therefore, fucoxanthin from S. siliquastrum can be a potential candidate for treating coronavirus infection.

Objectives : We investigated the effects of Sopungsungj-won(Shufengshunqjvuan) (SSEx1, SSEx2) on the metabolic syndrome in high-fat diet induced obese mice. Methods: 8 weeks old, high fat diet induced obese male mice were divided into 4 groups: C57BL/6 lean control, obese vehicle control, SSEx1, SSEx2. After mice were treated with SSExl, SSEx2 for 12 weeks, we measured body weight gain, food intake, feeding efficiency ratio, fat weight, plasma leptin, insulin, glucose and lipid levels. We also observe the morphology and count for the numbers of Adipocyte and evaluate the weight of organs and it's function. Results: 1. Compared to Obese Control Group, SSEx1 gained significantly lower body weight and showed lower Feeding Efficiency Ratio. 2. Compared to Obese Control Group, SSEx1 showed lower weights of epididymal adipose tissue, troperitoneal adipose tissue, inguinal adipose tissue, brown adipose tissue. SSEx2 showed higher weights of epididymal adipose tissue, troperitoneal adipose tissue, inguinal adipose tissue, brown adipose tissue. 3. Compared to Obese Control Group, the size of adipocytes was significantly decreased by SSEx1, whereas the number of adipocites per unit was significantly increased. Hepatic lipid accumulation was decreased significantly by SSEx1. 4. Concerning the weights of Liver, Heart, Spleen, Kidney and Pancreas, SSEx1, SSEx2 showed little differences with those of Lean Control, Obese Control. 5. Compared to Obese Control Group, SSEX1, SSEx2 showed lower level of plasma triglyceride, but SSEx1 had significance only. SSEx1, SSEx2 showed little lower level of plasma HDL-cholesterol. LDL-cholesterol, total cholesterol, but had no significances. 6. Concerning the levels of plasma glucose, insulin and leptin, SSEx1 and SSEx2 showed littele changes with those of Lean Control, Obese Control. 7. The leves of Plasma AST, AST, ALT, free fatty acid, BUN, creatinine were in the physiological range at 4 groups all: Lean Control, Obese Control, SSEx1, SSEx2. Conclusions : These results showed SSEx1 can be used as therapeutic agent for Obesity and metabolic syndrome caused by long-period high fat diet.

Purpose: Malnutrition is a significant issue for pediatric patients with cancer. We sought to evaluate the effectiveness and complication rate of percutaneous endoscopic gastrostomy (PEG) placement in pediatric oncology patients. Methods: A retrospective chart review was performed on 49 pediatric oncology patients undergoing PEG placement at Johns Hopkins All Children's Hospital between 2000 and 2016. Demographic and clinical characteristics, complications, absolute neutrophil count at time of PEG placement and at time of complications, length of stay, and mortality were identified. Weight-for-age Z-scores were evaluated at time of- and six months post-PEG placement. Results: The overall mean weight-for-age Z-score improved by 0.73 (p<0.0001) from pre- (-1.11) to post- (-0.38) PEG placement. Improvement in Z-score was seen in patients who were malnourished at time of PEG placement (1.14, p<0.0001), but not in those who were not malnourished (0.32, p=0.197). Site infections were seen in 12 (24%), buried bumper syndrome in five (10%), and tube dislodgement in one (2%) patient. One patient (2%) with fever was treated for possible peritonitis. There were no cases of other major complications, including gastric perforation, gastrocolic fistula, clinically significant bleeding, or PEG-related death documented. Conclusion: Consistent with previous studies, our data suggests a relationship between site complications (superficial wound infection, buried bumper syndrome) and neutropenia. Additionally, PEG placement appears to be an effective modality for improving nutritional status in malnourished pediatric oncology patients. However, larger prospective studies with appropriate controls and adjustment for potential confounders are warranted to confirm these findings.
