. The current Coronavirus pandemic has been linked to a dramatic increase in anti-Asian American and Pacific Islander (AAPI) hate incidents in the United States. At the time of writing, there does not appear to be any published empirical research examining the mechanisms underlying Asiaphobia during the current pandemic.

A 63-year-old gardener presented at our hospital with right upper orbital injury after falling on a bamboo basket. Neurological examination revealed right II, III, IV, and VI cranial nerve palsies.

View Article and Find Full Text PDFTrousseau syndrome is defined as a variant of intravascular thromboembolism that is induced by cancer. It may manifest itself as cerebral embolisms in some cases; however, when the cancer is not diagnosed, this identification may be difficult. Therefore, cerebral embolisms are often treated without identifying the cancer, which can worsen a patient's condition.

The analysis of the 16S rRNA gene by polymerase chain reaction amplification using universal primers and pathogen-specific primers was useful for the diagnosis and the investigation of serial detection status of the pathogen. This method may be helpful for the assessment of the frequency and the prediction of severity in M.

In particular, an intracranial NC with an enhanced mural nodule is extremely rare.
Case Description: A 20-year-old man presented with left-sided hearing disturbance and headache.
5-Aminolevulinic acid (5-ALA)-induced fluorescence-guided resection is a widely used procedure for patients with malignant gliomas. However, the clinical application of 5-ALA for surgery in primary central nervous system lymphoma (PCNSL) is uncommon. Here, we present a case of PCNSL treated using 5-ALA-induced fluorescence-guided resective surgery.

Pilocytic astrocytoma generally appears as a well-circumscribed, contrast-enhancing lesion, frequently with cystic components on magnetic resonance imaging (MRI). However, it has been reported that the MRI appearance of pilocytic astrocytoma may be similar to that of high-grade gliomas in some cases.
View Article and Find Full Text PDFIonizing irradiation is a well‑established therapeutic modality for malignant gliomas. Due to its high cellular uptake, 5‑aminolevulinic acid (ALA) is used for fluorescence‑guided resection of malignant gliomas. We have previously shown that 5‑ALA sensitizes glioma cells to irradiation in vitro.

Previously, we demonstrated that multi-dose ionizing irradiation with repetitive administration of 5-aminolevulinic acid (5-ALA) enhanced the host antitumor response and strongly inhibited tumor growth in experimental glioma. However, the mechanism of the radiosensitizing effect of 5-ALA is not known.

On admission, the RA disease activity was very high even after the treatment of methotrexate in other hospital. She underwent open biopsy to confirm a histopathological diagnosis of the intracranial lesions.

Porphyrin compounds act not only as photosensitizers but also as radiosensitizers. In the present study, the possible use of 5-ALA as a radiosensitizer for malignant gliomas was examined in vitro.

We report two cases of ruptured true Pcom aneurysms with some characteristic features of true Pcom aneurysm. A 43 year old man suffering from subarachnoid hemorrhage (SAH) had an aneurysm arising on the fetal-type Pcom artery itself, and underwent surgery for clipping.

Methods: Fourteen consecutive patients who were candidates for surgical treatment of meningiomas were prospectively analyzed with preoperative magnetic resonance imaging, including CE-FIESTA at 3 T. First, two neuroradiologists assessed several characteristics of the attachment of the meningioma to the dura mater or skull base on CE-FIESTA images.
A 12-month-old girl presented with a rare atypical choroid plexus papilloma manifesting as conscious disturbance and vomiting. Magnetic resonance (MR) imaging revealed a well-delineated 5 x 6-cm lobulate mass in the right lateral ventricle. Only partial removal of the tumor was performed because of excessive intraoperative hemorrhage at the first surgery.

In spinal lesions, there are a few rare cases of intramedullary hemorrhages associated with hemangioblastoma, and their prognoses were very severe.
Purpose: This is the first case of an intrasyrinx hemorrhage associated with hemangioblastoma in epiconus.
Ibudilast, an antagonist of platelet-activating factor receptors, was administered to patients with chronic subdural hematoma (CSDH) to assess its effectiveness in preventing recurrence. The remaining volumes of subdural hematomas on brain computed tomography were measured approximately 1-2 months after using ibudilast. The hematomas were significantly smaller and there was no recurrence.
