[Surgical Site Infections in Patients with Traumatic Brain Injury].

Patients with traumatic brain injury(TBI)have various pathological conditions, such as direct cell destruction by external force, compression by hematoma, vascular injury, ischemia, complicated hypoxia, and hypotension. These pathological conditions occur simultaneously at the time of injury. In some cases, contaminated wounds may be treated, and infection patterns different from the scheduled neurosurgical cases should be managed.

Changes in Outcomes after Discharge from an Acute Hospital in Severe Traumatic Brain Injury.

Neurological improvement occurs from the subacute to chronic phases in severe traumatic brain injury. We analyzed factors associated with improved neurological findings in the subacute phase, using data from the Japan Neurotrauma Data Bank (JNTDB). The subjects were 1345 patients registered in the JNTDB (Project 2015).

Combined Strategy of Burr Hole Surgery and Elective Craniotomy under Intracranial Pressure Monitoring for Severe Acute Subdural Hematoma.

Burr hole surgery in the emergency room can be lifesaving for patients with acute subdural hematoma (ASDH). In the first part of this study, a strategy of combined burr hole surgery, a period of intracranial pressure (ICP) monitoring, and then craniotomy was examined for safe and effective treatment of ASDH. Since 2012, 16 patients with severe ASDH with indications for burr hole surgery were admitted to Kenwakai Otemachi Hospital.

[Effect of Antithrombotic Drugs Reversal on Geriatric Traumatic Brain Injury].

Background: As the aging rate in the traumatic brain injury population increases, the number of patients taking antithrombotic drugs is also expected to increase among the population with traumatic brain injury; however, the utility or risk of reversal of such drugs is unclear. Therefore, we performed a retrospective cohort study of the effect of reversal of antithrombotic drugs on geriatric traumatic brain injury at our hospital.

Methods: The study subjects included 83 patients(65 years or older)with intracranial traumatic lesions or skull fractures who were admitted to our hospital during 2013-2018.

[Predictive Factors of Intracranial Pressure Elevation in Patients with Severe Acute Subdural Hematoma].

Introduction: Elevated intracranial pressure(ICP)can cause secondary brain injury after severe traumatic brain injury(TBI), and ICP is the key factor that determines the outcome. Therefore, prediction of elevation of ICP during the course of the injury would allow for more effective care of patients with severe TBI. In this study, we investigated predictive factors for elevation of ICP in patients with severe acute subdural hematoma(ASDH).

Risk of Deterioration of Geriatric Traumatic Brain Injury in Patients Treated with Antithrombotic Drugs.

Objective: Developed countries have rapidly aging populations and the use of antithrombotic drugs is increasing. We investigated the effects of antithrombotic drugs and reversal of these drugs in patients with geriatric traumatic brain injury (TBI).

Methods: Age, sex, mechanism of injury, Glasgow Coma Scale on admission, head computed tomography findings, antithrombotic therapy, acute exacerbation, and outcomes at discharge were examined in 711 patients with geriatric TBI, complicated with traumatic intracranial hemorrhage using data from the Japan Neurotrauma Data Bank Project 2015 (JNTDB P2015).

Probability of Soluble Tissue Factor Release Lead to the Elevation of D-dimer as a Biomarker for Traumatic Brain Injury.

d-dimer is a potential biomarker for the detection of traumatic brain injury (TBI). However, the mechanisms that trigger elevation of d-dimer in TBI remain unclear. The purpose of this study was to evaluate the reliability of d-dimer in blood as a biomarker for TBI and to determine the mechanisms involved in regulating its blood levels.

Cilostazol decreases duration of spreading depolarization and spreading ischemia after aneurysmal subarachnoid hemorrhage.

Objective: Traditionally, angiographic vasospasm (aVS) has been thought to cause delayed cerebral ischemia (DCI) after aneurysmal subarachnoid hemorrhage (aSAH). However, successful treatment of aVS alone does not result in improved neurological outcome. Therefore, there may be other potential causes of poor neurological outcome, including spreading depolarization (SD).

Successful endovascular treatment for thrombosed giant aneurysm of the V1 segment of the vertebral artery: A case report.

Thrombosed giant aneurysm of the V1 segment of the vertebral artery is rare, and there is controversy regarding the optimal method of treatment in this portion. Here, we report a thrombosed giant aneurysm of the V1 segment of the vertebral artery with a good clinical course with endovascular proximal artery occlusion of the vertebral artery. A 59-year-old woman presented with a large mass in the left side of the neck.

Fatty acid binding protein 7 regulates phagocytosis and cytokine production in Kupffer cells during liver injury.

Kupffer cells (KCs) are involved in the progression of liver diseases such as hepatitis and liver cancer. Several members of the fatty acid binding proteins (FABPs) are expressed by tissue macrophages, and FABP7 is localized only in KCs. To clarify the role of FABP7 in the regulation of KC function, we evaluated pathological changes of Fabp7 knockout mice during carbon tetrachloride-induced liver injury.
