OBJECTIVE: The objective of this study is to investigate clinical characteristics, management methods and possible causes of intracranial fusiform aneurysm. METHODS: Out of a series of 2,458 intracranial aneurysms treated surgically or endovascularly, 22 patients were identified who had discrete fusiform aneurysms. Clinical presentations, locations, treatment methods and possible causes of these aneurysms were analyzed. RESULTS: Ten patients of fusiform aneurysm were presented with hemorrhage, 5

Fluctuations in motor symptoms are mostly observed in Parkinson's disease (PD) patients. This characteristic is inevitable, and can affect the quality of life of the patients. However, it is difficult to collect precise data on the fluctuation characteristics using self-reported data from PD patients. Therefore, it is necessary to develop a suitable technology that can detect the medication state, also termed the "On"/"Off" state, automatically using wearable devices; at the same time, this coul

This study aimed to develop and validate an automated machine learning (ML) system that predicts 3-month functional outcomes in acute ischemic stroke (AIS) patients by combining clinical and neuroimaging features. Functional outcomes were categorized as unfavorable (modified Rankin Scale ≥ 3) or not. A clinical model employing optimal clinical features (Model_A), a convolutional neural network model incorporating imaging data (Model_B), and an integrated model combining both imaging and clinical

이 논문은 민사법리와 지적재산법리의 접점에서 발생하는 논점 중의 하나인 일반불법행위법리에 의한 지적재산법의 보완 문제를 다룬다. 최근 개개의 지적재산법으로 보호되지 않는 타인의 지적 성과물 등의 무단이용행위가 민법상 불법행위에 해당하는지 여부를 둘러싼 논의가 활발히 전개되고 있다. 현행 지적재산법의 입법적 흠결로 인해 법적 보호가 미흡한 정보들에 대해 불법행위법리에 의한 보호가 도모됨으로써 불법행위법은 지적재산법을 보완하는 역할을 수행하고 있다. 최근 우리나라의 대법원 결정과 몇몇 하급심 판결을 통해서 지적재산법의 침해가 부정되었지만 민법상 불법행위책임이 긍정된 사례들을 확인할 수 있다. 무엇보다 하급심 판결들은 저작권에 의한 보호를 부정하면서도 “부정하게 스스로의 이익을 꾀할 목적으로 이를 이용하거나 또는 원고에게 손해를 줄 목적에 따라 이용하는 등의 특별한 사정이 있는 경우”에는 불법행위책임을 인정할 수 있다고 판시하였다. 또한 대법원 결정은 불법행위책임으로서 손해배상 외에 일정

Background and aims: Predicting the prognosis of acute ischemic stroke (AIS) is crucial in a clinical setting for establishing suitable treatment plans. This study aimed to develop and validate a machine learning (ML) model that predicts the functional outcome of AIS patients and provides interpretable insights. Methods: We included AIS patients from a multicenter stroke registry in this prognostic study. ML-based methods were utilized to predict 3-month functional outcomes, which were categoriz

BACKGROUND AND PURPOSE: The identification of high-risk patent foramen ovale (PFO) is important for selecting suitable patients for PFO closure to prevent recurrent stroke in those with cryptogenic stroke. We aimed to evaluate the predictability of transcranial Doppler (TCD) in diagnosing high-risk PFO compared with that of transesophageal echocardiography (TEE), which is not feasible for some stroke patients. METHODS: We retrospectively reviewed the data of 461 cryptogenic stroke patients who u

Objectives The aim of this exploratory study was to investigate the underlying pathomechanisms of migraine with aura (MA) and migraine without aura (MO) in the interictal phase using a connectivity analysis. Methods We prospectively enrolled patients who were newly diagnosed with migraine. All patients underwent brain MRI, including diffusion tensor imaging and arterial spin labeling perfusion MRI. We analyzed the differences between patients with MA and those with MO in structural connectivity

The location of ganglioglioma (GG) within the infratentorial compartment is unusual. The authors report a rare case of GG in the cerebellar hemisphere. A 12-year-old boy suffered from headache and gait disturbance. Neuroimaging studies demonstrated a large enhancing cerebellar mass with cystic components compressing the forth ventricle. After complete resection of the tumor, the patient became symptom free. Histological examination on the tumor disclosed glial cells and dysplastic ganglion cells

엔터테인먼트산업에서 가장 대중의 각광을 받는 사람은 연예인이라 지칭되는 저작권법상의 實演者이다. 일반적으로 실연자는 예명을 사용하여 연예활동을 하므로 실연자의 예명에 대한 법적 보호 문제가 대두된다. 이에 관하여 이 논문은 다음과 같은 구성으로 고찰하였다. 첫째, 실연자의 예명은 인격권의 보호대상인가에 관하여 검토하였다. 실연자의 예명도 일반적 인격권 내지 개별적 인격권으로서의 성명권 또는 성명표시권의 보호대상이 될 것인가 하는 점이다. 이와 관련하여 성명권 일반을 개관하고 그 보호대상인 예명에 대하여 살펴본 다음 개별적 인격권에 해당하는 성명표시권과 그 보호대상인 예명 및 성명권과 성명표시권의 관계에 대해서 고찰하였다. 즉, 실연자의 널리 알려진 예명은 성명권의 보호대상이 되므로 이러한 예명은 일반적 인격권에 의하여 보호된다는 것과, 성명권과는 별개의 권리인 실연자의 성명표시권은 저작권법에 명문의 규정이 있으므로 개별적 인격권으로 보호되는데, 이때의 성명에도 예명이 포함된다는 점을

Endovascular coil surgery for patients with unruptured intracranial aneurysms is characterized by low procedural mortality and morbidity and has advantages in patients with poor general health, cerebral infarction, posterior circulation aneurysms, aneurysms of the proximal internal cerebral artery, and unruptured aneurysms associated with ruptured aneurysm. For the management of unruptured aneurysms, endovascular coil surgery is considered an attractive alterative option.

A fenestration of the supraclinoid internal carotid artery (ICA) is a rare congenital condition. We report an aneurysm arising from the proximal end of an ICA fenestration that was treated by endovascular coiling. Three-dimensional rotational angiography of preoperative cerebral angiography provided an understanding of the complex anatomy of the aneurysms associated with the fenestration and may facilitate the clinical decision regarding the treatment option. Endovascular coiling appears to be s

BACKGROUND: We correlated the tumor proportion score (TPS) of programmed cell death ligand 1 (PD-L1, SP263 or 22C3) expression with the disease control rate (DCR, partial remission and stable disease), and progression free survival (PFS) after nivolumab or pembrolizumab treatment. METHODS: A total of 70 case records (55 males, 15 females) of patients with non-small cell lung cancer (NSCLC, 46 adenocarcinoma, 22 squamous cell carcinoma, and two others) were reviewed. The PD-L1 expressions were di
