Abstract
To investigate the effect of the therapeutic treatment of the immunopeptide, peptide inhibitor of trans-endothelial migration (PEPITEM) on the severity of disease in a mouse model of experimental autoimmune encephalomyelitis (EAE) as a model for human multiple sclerosis (MS), a series of experiments were conducted. Using C57BL/6 female mice, we dosed the PEPITEM in the EAE model via IP after observing the first sign of inflammation. The disease was induced using MOG35-55 and complete Freund's adjuvants augmented with pertussis toxin. The EAE score was recorded daily until the end of the experiment (21 days). The histological and immunohistochemistry analysis was conducted on the spinal cord sections. A Western blot analysis was performed to measure the protein concentration of MBP, MAP-2, and N-Cadherin, and ELISA kits were used to measure IL-17 and FOXP3 in the serum and spinal cord lysate. The therapeutic treatment with PEPITEM reduced the CNS infiltration of T cells, and decreased levels of the protein concertations of MBP, MAP-2, and N-Cadherin were observed, in addition to reduced concertations of IL-17 and FOXP3. Using PEPITEM alleviated the severity of the symptoms in the EAE model. Our study revealed the potential of PEPITEM to control inflammation in MS patients and to reduce the harmful effects of synthetic drugs.

Abstract
Background: Metastatic brain lesions, of thyroid origin, are rare manifestations of differentiated thyroid cancer, with papillary thyroid carcinoma being the most common subtype. Considering the rarity of metastatic follicular thyroid carcinoma to the brain, the present article outlines its clinical presentation, neuroradiological findings, pathological features, and outcome. Case Description: A 52-year-old female presented with a 6-month history of progressive and holocephalic headache. Examination revealed a tracheal deviation to the left side due to an enlarged goiter. Brain CT scan showed a right occipital, slightly hyperdense lesion associated with a 0.4 cm midline shift to the left side. Brain MRI demonstrated a right occipital, avidly-enhancing, extra-axial lesion with disproportionate and extensive vasogenic edema. As the lesion was solitary, the patient underwent craniotomy and tumor resection. Histopathological examination revealed a tumor consistent of small follicles, composed of uniform round nuclei without papillary thyroid carcinoma nuclear features, suggestive of metastatic follicular thyroid carcinoma to the brain. Postoperatively, the patient was neurologically intact. She was discharged in a stable condition with laboratory/ radiological investigations and follow-up at neurosurgery, endocrine, radiotherapy, and thyroid surgery clinics. Conclusion: Follicular thyroid carcinoma may rarely metastasize to the central nervous system. A high index of suspicion is required to identify patients with thyroid cancer who initially present with neurological manifestations. Complete surgical resection of the metastatic brain lesion is safe, feasible and is associated with a prolonged overall survival.

Abstract
Neuroepithelial tumors, formerly known as primitive neuroectodermal tumors of the central nervous system, are reclassified under embryonal tumors in the 2016 WHO Classification of Tumors of the Central Nervous System. The tumor has two known genetic alterations: HGNET-MN1 and HGNET-BCOR. Previously, radiological features of the tumor have been reported as large, intra-axial lesions in the cerebral or cerebellar hemisphere, which presents mild adjacent edema. Here, we report the first case of high-grade neuroepithelial tumor not elsewhere classified (HGNET-NEC) arising from the cerebellar vermis, demonstrating good outcomes in clinical follow-up when compared with previously known types.

Abstract
Background: Neurosarcoidosis is a rare disease. In the spine, it commonly presents as an intramedullary lesion. Epidural spinal lesions are extremely rare. Case Description: A 29-year-old patient presented with a 22-month history of progressive neck, upper limb pain, and myelopathy. The cervical MRI showed a large epidural mass infiltrating the paraspinal soft tissue. After an open biopsy, the diagnosis of neurosarcoidosis was established and was followed-up by appropriate medical management. Conclusion: To manage cervical epidural neurosarcoidosis, first, you must obtain a tissue diagnosis and then follow with appropriate medical management.

Abstract
Improved survival rates in premature infants and more sensitive neuroimaging techniques have expanded the scope of recognized neurodevelopmental disabilities in this vulnerable population and have implicated a role for cerebellar pathology in their origin. Although supratentorial pathologies are well studied, cerebellar pathology has been under-recognized in premature infants. The purpose of this review is to provide a concise description of established acquired cerebellar pathologies in premature infants including cerebellar atrophy/hypoplasia, hemorrhage, and infarction. The cerebellum develops over an extended period during which time cerebellar injury tends to occur with the potential to derail the cerebellum from its expected growth trajectory and perturb the establishment of cerebellar neural circuitry. The occurrence of cerebellar injury in this vulnerable period may have life-long implications that extend beyond the immediate damage sustained by the cerebellum, all of which needs to be considered as we research the causes and effects of neurodevelopmental disabilities in these patients.

Abstract
Pattern recognition and cytologic features remain essential diagnostic tools in pathology. Viral cytopathic effect may be the first clue to a diagnosis of a viral infection. This paper aims to provide a brief illustrated summary of the histopathologic changes caused by commonly encountered and rare viruses. The list of viruses discussed with characteristic viral inclusions or distinctive cytopathic effect includes cytomegalovirus, adenovirus, herpes virus (herpes simplex virus and varicella zoster virus), human papillomavirus, respiratory syncytial virus, parvovirus, poxvirus (molluscum contagiosum virus), and polyoma virus (JC virus and BK virus). Also reviewed are the characteristic histologic and cytopathic changes for Epstein-Barr virus (EBV), Paramyxoviruses (human parainfluenza virus and measles virus), human immunodeficiency virus (HIV), and hepatitis B virus.
