Meningioma is a common neoplasm of the central nervous system; however, primary extracranial meningioma of the paranasal sinus, especially the maxillary sinus, is rare. We report a case of primary extracranial meningioma (fibrous type) of the maxillary sinus and present a literature review of the imaging features that correlate with fibrous meningioma.

Mushrooms are known for their various attributes in the fields of nutrition and therapeutics. With exceptional taste, aroma, and nutritional value, they are considered ‘functional food’-improving health and providing nutritional benefits to the body. Mushrooms have also been widely applied therapeutically as they possess diverse bioactive compounds known as secondary metabolites. These secondary metabolites demonstrated diverse biological properties such as anticancer, anti-diabetic, immunomodulatory, antimicrobial, anti-inflammatory, antiviral, anti-allergic, and antioxidative activities. This review presents bioactive compounds from the field of mushroom metabolite research and discusses important findings regarding bioactive compounds identified during the last five years (2015 – 2019).

BACKGROUND AND PURPOSE: Chronic simulated snoring was induced in rabbits to determine the impact of snoring on the development of atherosclerosis. METHODS: The pressure wave of induced snoring at the carotid bifurcation of rabbits was acquired by gently pressing the airway. This wave was then simulated using custom-made mechanical devices. Twelve rabbits were used in this study, seven of which were assigned to the experimental group and the remaining five formed the control group. All of the rabbits were raised on a 1% high-cholesterol diet. Either working or sham devices were positioned at the ventral center of the neck in each rabbit. At the end of a 2-month observation period, all of the rabbits were sacrificed by perfusion fixation, the carotid arteries harvested, and the carotid atherosclerosis histology reviewed. RESULTS: All of the rabbits survived to the end of the experimental period. Blood sampling revealed the presence of hypercholesterolemia in both groups, with no significant difference between them. The presence and degree of atherosclerosis did not differ significantly between the groups. CONCLUSIONS: The findings of this study show the feasibility of making a chronic simulated snoring rabbit model. However, the causative role of snoring in carotid atherosclerosis was not detected in this animal study.

BACKGROUND: Semiology of epileptic seizure is very important for diagnosis and treatment. However, little is known about the reliability of the observers' description. This study aims to determine the description reliability of seizures in the aspects of classification and lateralization. METHODS: We recorded 72 patients with habitual seizures during video-EEG monitorings. We, then, compared the ictal behaviors described by frequency observers and those recorded on the videotape to compare the accuracy of the observers' descriptions. Finally, we reviewed which aspects of the informants affected the reliability of the data. RESULTS: The classification of seizures based only on the observer-description was somewhat discordant from the videotape (correct classification: 82%) especially in dividing simple partial from complex partial seizures. Description of many ictal behaviors in presumed complex partial seizure such as oroalimentary automatism, motionless staring, tonic/clonic posture and version was accurate except for the hand automatism. A specified direction by the observer has a very high true positive rate. The accuracy of the description was related to the educational status of the observer. CONCLUSIONS: Semiology description by well-educated observers is may be reliable, but every physician should keep its limitation in mind and judge accordingly.

Distinct from migraine with aura or hemiplegic migraine, a rare clinical entity of migraine-like headache, transient focal neurologic deficit and CSF pleocytosis (HaNDL) has been known. Although the etiology or pathogenesis is unknown, possibility of viral infection or inflammation has been suggested. We report a 25-year-old man diagnosed as HaNDL with literature review.

RATIONAELE: Secondary bilateral synchrony(SBS) is not an unusual finding to the EEGers, but its Significance is not well-delineated. We reviewed the clinical EEG, and neuroimaging characteristicts in patients with SBS. METHOD: Patients who were admitted for presurgical evaluation of intractable epilepsy were classified on the basis of video-EEG monitoring, prolonged interictal EEG, MRI, ictal SPECT, PET, and, in a few cases, the surgical results. We analyzed clinical, electrophysiological, and neuroimaging characteristics of patients with SBS by comparing them, with those without SBS. RESULTS: Among 319 patients who were admitted for presurgical epilepsy evaluation, 26 patients had SBS(8.2%). Medial temporal lobe epilepsy was predominant as a whole(140/319, 43.9%), but frontal lobe epilepsy(FLE) was main syndrome in the SBS group(16/26, 61.5%). Multifocal irritative zones were present in 12.5% of FLE with SBS group(2/16) and in 4.8% of FLE without SBS group(2/42). In FLE with SBS group, the location of ictal onset zone was parasaggital in 32%(5/16) and multifocal in 37%(6/16). There was a tendency to develop secondary generalized tonic clonic seizure in FLE with SBS group than in FLE without SBS group. Neuroimaging modalities revealed frontal abnormalities more accurately in FLE with SBS group than in FLE without SBS group. CONCLUSION: Frontal lobe as an epileptogenic zone is an important factor in generating SBS and SBS seems to facilitate seizure spreading to the contralateral hemisphere.

We describe our experience regarding metronidazole-induced encephalopathy in a patient with acute lymphoblastic leukemia during chemotherapy. A 17-year-old girl was admitted to our institution with complaints of abdominal pain and mucoid stools. She was diagnosed with acute lymphoblastic leukemia and had been undergoing intensified chemotherapy protocol. During the fifth week of interim maintenance-1 therapy, she developed a fever and complained of chills. On stool examination, stool occult blood was positive and Clostridium difficile toxin A/B test was positive. She was started on metronidazole treatment for possible Clostridium difficile infection and other inflammatory gastrointestinal diseases. Ten days later, the patient complained of dizziness and nausea. A brain MRI was performed to make a differential diagnosis of any chemotherapy- induced CNS complication such as necrotizing leukoencephalopathy. The brain MRI showed features of metronidazole-induced encephalopathy. Metronidazole was discontinued and symptoms started to subside four days after. A follow-up brain MRI performed at four weeks showed that lesions of the dentate nucleus had disappeared.
