A 18-month-old, male Maltese dog with acute seizure was referred to Veterinary Medical Teaching Hospital, Kyungpook National University. Abnormal neurologic findings included a tendency to fall to the left, turn and circle to the right, negative bilateral menace responses and pupillary light reflexes, and diminished responses to facial sensation testing on both sides. Radiographic signs were normal, except for occipital dysplasia. Magnetic resonance imaging of the brain revealed bilateral asymmetric ventriculomegaly, which is more on left side. Cerebral edema was also suspected. The dog died after 9 days from the onset of seizure, and a necropsy was performed. Histopathologically, the brain lesions in the meninges and the cerebral cortex of this dog was presented. There was severe diffuse nonsuppurative inflammation in perivascular area of the meninges and the cerebral white matter. Based on the results, this case was diagnosed as necrotizing meningoencephalitis in Maltese dog.

Objective: The purpose of this study is to report the case of a patient with non-small cell lung cancer (NSCLC) with Programmed cell death protein 1 (PD-1) mutation treated by Integrative Medicine Therapy (IMT). Methods: A patient with metastatic NSCLC received pembrolizumab 200mg intravenously for every 3 weeks from July 2017. Repeat cycle every 3 weeks since July 2017. The patient has been treated with Integrative Medicine Therapy (IMT) since December 2016. The tumor size was measured by computed tomography (CT) and magnetic resonance imaging(MRI). Adverse events were evaluated by the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE), version 5.0. Results: After combined treatment, the extent of proximal portion of primary tumor in the left lower lobe was decreased and disease status was stable radiologically. No evidence of newly developed metastatic lesions in the brain since May 2017. The patient did not experience any adverse event according to NCI-CTCAE ver. 5.0. Conclusion: This case study suggests that Integrative Medicine Therapy (IMT) may contribute to tumor response, in conjunction with Pembrolizumab on the treatment of patients with NSCLC.

Background: Although orthostatic hypotension (OH) and cognitive impairment (CI) are common non- motor symptoms of Parkinson's disease (PD), the relationship between OH and CI remains to be clarified. This study was aimed to investigate the relationship between OH and CI in PD. Methods: We recruited 192 patients who were diagnosed as PD based on the UK Brain Bank diagnostic criteria. The Hoehn & Yahr stages were ranged I to III and patients underwent extensive clinical evaluation, including brain magnetic resonance imaging (MRI) for cerebral white matter hyperintensity (WMH), tilt table test, the Korean version of Montreal Cognitive Assessments and the Korean version of Mini-Mental Status Examination in one month from the first clinic visit. The participants were divided into two groups according to the presence of OH (OH+ vs. OH-) and cognitive function (cognitive normal, CN vs. CI), respectively. Results: Significant relationship between OH and cognitive function (p=0.04) was found in our patients. The patients with OH+ had higher risk of CI by 2.6 times than that of OH- patients. Maximum heart rate change during tilt table test was correlated with cognitive function and white matter changes, whereas blood pressure change during tilt table test showed no correlation with those parameters. Conclusions: There was significant relationship between OH and CI in PD. Therefore, PD patients with either symptom may need periodic evaluation and proper management for OH and cognitive functions.

There have been many studies from the genetic system to physical activity and emotional expression such that there are gender differences. The purpose of this study was to determine how the structural characteristics of cortical thickness differ between males and females. This study used data from the Human Connectome Project (HCP). To analyze age-specific sexual dimorphisms of cortical thickness, selected 8-80 year old subjects were divided into five detailed age range groups according to each criterion. A total of 1,700 individual brain MRI T1 data were registered in stereotaxic space for analysis and classified into white matter (WM), gray matter (GM), and cerebro-spinal fluid (CSF). For surface-based analysis, the WM/GM surface was reconstructed from a spherical polygon model with 40962 vertices per hemisphere, and each vertex was extended to the GM/CSF boundary. Cortical thickness was then measured between each vertex using the t-link method. In the statistical analysis, intracranial volume was used as a covariate to exclude the effect of the difference in brain size of each individual, and the result of using age as a covariate was added to confirm the age effect within each group. Gender differences in cortical thickness had significant results by group. This may be an index to explain diseases with sexual dimorphism in prevalence or become a basis for explaining the characteristics of each sex that appear in behavior, personality, and aging. Therefore, the results of our study could be a criterion for age classification in future studies and for understanding 'normal' sexual dimorphism.

A 5-month-old female domestic short-haired cat presented with a history of seizure episodes for two months following an animal bite injury to the head. There were no remarkable findings on physical and neurological examination or blood analysis. Computed tomography revealed a fracture of the left parietal bone with an inward displacement of the bone fragment while magnetic resonance imaging revealed an enlarged temporal horn of the left lateral ventricle and a pseudomeningocele compressing the adjacent cerebral parenchyma. Subsequently, cerebrospinal fluid analysis results were normal. The patient was diagnosed with traumatic brain injury (TBI), with subsequent post-traumatic hydrocephalus (PTH) and pseudomeningocele. Despite treatment with phenobarbital and levetiracetam, seizures were not sufficiently controlled. Craniectomy for bone fragment removal and duraplasty were performed after a week. The patient then returned to normal condition with no further seizure activity. On repeated MRI two months after discharge, the hydrocephalus of the lateral ventricle and pseudomeningocele were enlarged; however, the patient maintained a good clinical status without any neurological signs. To the best of our knowledge, PTH and intracranial pseudomeningoceles have not yet been reported in cats. PTH and pseudomeningocele are among the complications of TBI and may not have any significant relevance with the clinical signs in this case. Thus, to broaden our knowledge about PTH and pseudomeningocele in cats, we describe serial changes in the clinical findings of this cat over the treatment period.

1. Objectives Creutzfelt Jacob Disease is one of a group of neurodegenerative disorders causing spongiform encephalopathies due to a infection of prion or unconventional slow virus on central nerve system. The diagnosis of this disease is not easy and there is currently no cure. This article is to report our case about a female patient who was not diagnosed as CJD at the early period so that we treated her with Yangkyuksanhwa-tang(凉膈散火湯) and Jihwangbaekho-tang(地黃白虎湯). 2. Methods Magnetic resonance imaging(brain MRI), blood test and computer tomography were performed. The treatment for this patient was clinically based on Sasang Constitutional Medicine. 3. Results and Conclusions (1) Visual field defect, ataxia, myoclonus, sweating and dysuria were the main symptoms of the patient. (2) The pathological change in parenchyme was not revealed during the early periods by MR imaging. So the diagnosing CJD was not possible during the time in this case. (3) Jihwangbaekho-tang(地黃白虎湯) improved her myoclonus and sweating. Bur her mental disorder and the progress of the pathological change in the parenchyme was not able to be treated.

Objectives Local gyrification reflects the early neural development of cortical connectivity, and is regarded as a potential neural endophenotype in psychiatric disorders. Several studies have suggested altered local gyrification in patients with bipolar I disorder (BD-I). The purpose of the present study was to investigate the alterations in the cortical gyrification of whole brain cortices in patients with BD-I. Methods Twenty-two patients with BD-I and age and sex-matched 22 healthy controls (HC) were included in this study. All participants underwent T1-weighted structural magnetic resonance imaging (MRI). The local gyrification index (LGI) of 66 cortical regions were analyzed using the FreeSurfer (Athinoula A. Martinos Center for Biomedical Imaging). One-way analysis of covariance (ANCOVA) was used to analyze the difference of LGI values between two groups adjusting for age and sex as covariates. Results The patients with BD-I showed significant hypogyria in the left pars opercularis (uncorrected-p = 0.049), the left rostral anterior cingulate gyrus (uncorrected-p = 0.012), the left caudal anterior cingulate gyrus (uncorrected-p = 0.033). However, these findings were not significant after applying the multiple comparison correction. Severity or duration of illness were not significantly correlated with LGI in the patients with BD-I. Conclusions Our results of lower LGI in the anterior cingulate cortex and the ventrolateral prefrontal cortex in the BD-I group implicate that altered cortical gyrification in neural circuits involved in emotion-processing may contribute to pathophysiology of BD-I.

Contrast enhanced magnetic resonance imaging using gadolinium-based contrast agent (GBCA) is a very useful in vivo technique to visualize the inner ear pathology including endolymphatic hydrops. Although systemic intravenous (IV) administration can visualize the perilymph space, the visualization was possible by indirect passage of contrast agent through blood-perilymph barrier. All animal experimental procedures were performed under anesthesia with 5% isoflurane. Lipopolysaccharide (LPS) was instilled into the left tympanic cavity through the tympanic membrane using a sterile 27gauge needle to induce hydrops model. Tucker-Davis Technologies system was used to measure Auditory Brainstem Responses (ABRs). For intracerebroven-tricular (ICV) administration, 25 µmol of GADOVIST (Bayer, Berlin, Germany) was used and diluted GADOVIST injection was 10 µl. MR imaging was acquired with a 9.4 Tesla MRI scanner. Transmit-receive volume coil with 40 mm inner diameter and 75 mm out diameter was used. ICV administration well demonstrated the strong enhancement along the cerebrospinal fluid (CSF) microcirculation pathway including CSF fluid in the subarachnoid space and CSF space of the inner ear structures. On the other hand, IV administration showed no contrast enhancement along the CSF microcirculation pathway and showed weak enhancement in the inner ear structures. In case of rat hydrops model, ICV administration showed that the reduced contrast enhancement in the perilymph space of the hydrops induced inner ear compared to the contrast enhancement in the perilymph space of the normal inner ear. New systemic ICV administration method provide contrast enhancement of GBCA in the inner ear through CSF microcirculation pathway.
