Usefulness of cerebrospinal fluid presepsin (soluble CD14 subtype) as a new marker in the diagnosis of neurosurgical postoperative meningitis.

Objective: To determine the usefulness of cerebrospinal fluid (CSF) presepsin in the diagnosis of neurosurgical postoperative meningitis (POM).

Methods: The study included patients admitted to the Department of Neurosurgery, Toho University Medical Center Omori Hospital from May 1, 2020 to March 31, 2022 with suspected meningitis after neurosurgery who clinically required CSF sampling and patients who underwent CSF sampling for examination of idiopathic normal pressure hydrocephalus (iNPH). Participants were divided into a POM and a postoperative non meningitis (PONM) group based on the POM diagnostic criteria established for this study.

Metastasis infiltrating tumor to meningioma: a case report.

Background: There have been many reports of tumor-to-tumor metastasis, in which cancer metastasizes directly into meningiomas. However, metastasis infiltrating tumors in which cancer metastasizes around meningiomas are rare. Therefore, we report a case of metastasis originating from lung cancer that infiltrated meningioma.

Diagnosis and treatment of vertebral artery injuries due to blunt trauma: A case series.

Blunt traumatic vertebral artery injuries are rare, but they cause rapid secondary strokes with worsening prognoses. We report four blunt traumatic vertebral artery injury cases that were diagnosed before developing stroke and successfully treated with coil embolization. All four patients were male, aged between 45 and 71 years (mean 57 years).

Repeated intracranial empyema following cranioplasty in a patient with atopic dermatitis: a case report.

Background: Atopic dermatitis is a chronic inflammatory skin disease associated with pruritus. Skin affected by atopic dermatitis not only shows a high percentage of Staphylococcus aureus colonization, but corneal barrier dysfunction is also known to occur. It is considered a risk factor for bacterial infections in various areas of the body.
