Hybrid Endovascular and Direct Surgical Approach for Treatment of Penetrating Common Carotid Artery Injury: A Case Report.

Although rare, penetrating cervical vascular injury poses significant challenges with a poor patient prognosis, often attributed to severe hemorrhage and accompanying injuries. We encountered a case of hemorrhagic shock resulting from a penetrating injury to the common carotid artery (CCA), which was successfully managed using a combination of endovascular therapy and direct surgical intervention. A 23-year-old man presented with a self-inflicted stab wound on the left side of his neck from a kitchen knife.

Endoscopic Cerebellar Necrosectomy for Space-occupying Cerebellar Infarction: A Case Report.

Suboccipital decompressive craniectomy with or without resection of necrosis is the preferred treatment for space-occupying cerebellar infarctions with neurological deterioration due to brainstem compression and obstructive hydrocephalus. We herein present our experience with treating space-occupying cerebellar infarctions successfully using endoscopic necrosectomy. A total of 27 patients were admitted to our hospital due to cerebellar infarctions between April 2021 and November 2023.

Endoscopic Endonasal Approach for Optic Canal Dural Metastasis in a Patient with Progressive Visual Dysfunction: A Case Report.

To improve optic nerve function in a patient with progressive visual dysfunction, performing early decompressive and debulking surgery for a metastatic tumor located in the optic canal is essential. The endoscopic endonasal approach could be a practical and effective alternative for lesions in the inferomedial part of the optic canal. A 66-year-old man with a right visual eye field deficit had multiple lesions in the pineal gland, occipital lobe, and right inferomedial optic canal.

Bifocal germ cell tumor of pineal germinoma and neurohypophyseal embryonal carcinoma: illustrative case.

Background: Bifocal germ cell tumors, with primarily identical tissue composition, occur concurrently in the neurohypophyseal and pineal regions.

Observations: A 16-year-old male patient exhibited increased intracranial pressure symptoms, with concurrent tumors in the pineal and neurohypophyseal regions, causing obstructive hydrocephalus. His serum human chorionic gonadotropin level was elevated, measuring 506.

Brain-specific glycosylation enzyme GnT-IX maintains levels of protein tyrosine phosphatase receptor PTPRZ, thereby mediating glioma growth.

Gliomas are the most prevalent primary tumor of the central nervous system. Despite advances in imaging technologies, neurosurgical techniques, and radiotherapy, a cure for high-grade glioma remains elusive. Several groups have reported that protein tyrosine phosphatase receptor type Z (PTPRZ) is highly expressed in glioblastoma, and that targeting PTPRZ attenuates tumor growth in mice.

[Metastatic Brain Tumor from Urachal Cancer:A Case Report].

Urachal cancers usually do not metastasize until the late stages, and local invasion and recurrence are observed with high frequency. We report a rare case of brain metastasis from urachal cancer in a 67-year-old female. She presented with abnormal behavior and right hemiparesis that started one month previously.

Exclusive Cerebellar and Leptomeningeal Metastases from Early Gastric Cancer 14 Months after Proximal Gastrectomy: An Autopsy Case Report.

We report a rare autopsy case in which the patient received gastrectomy after an endoscopic diagnosis of early gastric cancer, and had deteriorated due to exclusive metastatic cerebellar tumors identified 14 months after surgery. A 65-year-old male was diagnosed as having a 0-IIc-type early gastric cancer on the posterior wall of the upper stomach by gastrointestinal endoscopy in search of a cause of epigastralgia, and thus received proximal gastrectomy and pyloroplasty. Although the tumor was in the early stages and limited within the mucosal layer, adjuvant chemotherapy was started by using S-1 80 mg daily due to evidence of metastasis into lymph node #3 at the lesser curvature.

Post-traumatic Stress and Growth Among Medical Student Volunteers After the March 2011 Disaster in Fukushima, Japan: Implications for Student Involvement with Future Disasters.

The March 2011 "triple disaster" (earthquake, tsunami, and nuclear accident) had a profound effect on northern Japan. Many medical students at Fukushima Medical University volunteered in the relief effort. We aimed to investigate the nature of students' post-disaster involvement and examine the psychological impact of their experiences using a survey containing elements from the Davidson Trauma Scale and Posttraumatic Growth Inventory.
