Nonconvulsive Status Epilepticus Caused by Cerebrospinal Fluid Dissemination of a Salivary Duct Carcinoma: A Case Report.

Salivary duct carcinoma (SDC) is a rare and highly aggressive salivary gland tumor with rapid growth, distant metastasis, and a high recurrence rate. Moreover, the parotid gland is the most common site with a poor prognosis. A lower frequency of distance metastasis to the liver, skin, and brain has also been reported, although the lungs, bones, and lymph nodes are the most common sites of SDC metastasis.

Psychiatric disorders of the combination of levetiracetam either with lacosamide or perampanel: a retrospective cohort study.

Background The number of patients with epilepsy receiving perampanel or lacosamide as an add-on treatment following levetiracetam treatment has increased. Although levetiracetam causes psychiatric disorders, it is unclear whether they occur with the combined use of these antiepileptic drugs. Objective To determine the frequency of psychiatric disorders in patients received lacosamide or perampanel in combination with levetiracetam.

Endogenous genetic risk factor for serious heatstroke: the thermolabile phenotype of carnitine palmitoyltransferase II variant.

Aim: In serious heatstroke, elevated body temperature (>40°C) is considered the main cause of illness. Mitochondrial carnitine palmitoyltransferase II (CPT II) plays an important role in adenosine triphosphate (ATP) generation from long-chain fatty acids, and its thermolabile phenotype of polymorphisms leads to ATP production loss under high fever. Whether by heatstroke or influenza, high fever suppresses mitochondrial ATP production in patients with the thermolabile phenotype of polymorphisms.

Prediction of Early Death in Patients With Sepsis-Associated Coagulation Disorder Treated With Antithrombin Supplementation.

For success in clinical trials, eliminating inclusion of patients with irreversible recovery is important. The purpose of this study was to identify the patient population who do not survive for more than 3 days. A total of 449 patients with sepsis suspected of having disseminated intravascular coagulation (DIC) and treated with antithrombin were examined.

Empirical research on the utility of a preparation manual for a disaster medical response drill.

Purpose: It is difficult for emergency physicians to plan and execute a disaster medical response drill while conducting their daily work activities. Readily available drill preparation manuals are therefore essential, alongside assessment methods to ensure quality. Here, we propose email text analysis as a manual assessment method, and investigate its validity.

Phase I/II trial of combination of temozolomide chemotherapy and immunotherapy with fusions of dendritic and glioma cells in patients with glioblastoma.

Background: This trial was designed to evaluate the safety and clinical responses to a combination of temozolomide (TMZ) chemotherapy and immunotherapy with fusions of DCs and glioma cells in patients with glioblastoma (GBM).

Method: GBM patients were assigned to two groups: a group of recurrent GBMs after failing TMZ-chemotherapy against the initially diagnosed glioma (Group-R) or a group of newly diagnosed GBMs (Group-N). Autologous cultured glioma cells obtained from surgical specimens were fused with autologous DCs using polyethylene glycol.

Procalcitonin levels predict to identify bacterial strains in blood cultures of septic patients.

Background: We examined whether the values obtained from principal component analysis (PCA) on laboratory tests can be used to predict bacterial infections and identify bacterial strains in blood culture (BC).

Method: This study is a single-center retrospective analysis of 315 patients suspected of having sepsis. We applied PCA on procalcitonin (PCT) and laboratory test biomarkers, namely, platelet (PLT), white blood cell, and C-reactive protein (CRP) as well as BC.

Investigation and treatment of pulmonary embolism as a potential etiology may be important to improve post-resuscitation prognosis in non-shockable out-of-hospital cardiopulmonary arrest: report on an analysis of the SOS-KANTO 2012 study.

Background: The prognosis of non-shockable out-of-hospital cardiac arrest is worse than that of shockable out-of-hospital cardiac arrest. We investigated the associations between the etiology and prognosis of non-shockable out-of-hospital cardiac arrest patients who experienced the return of spontaneous circulation after arriving at hospital.

Methods And Results: All subjects were extracted from the SOS-KANTO 2012 study population.

[Burns].

Burns extending deep into the skin and those affecting a wide surface area trigger various responses in the body and pose a serious threat to life. Therefore, the degree of severity needs to be determined accurately, and appropriate transfusion and local management should be provided accordingly. Systematic and meticulous management that considers not just the risk of death but also functional prognosis is essential from the early stage of burn injuries.

[A Case of Foix-Alajouanine Syndrome due to Perimedullary AVF: Remission and Aggravation Mechanism Considered by an Open Surgical Biopsy and Intraoperative ICG Angiography].

Foix-Alajouanine syndrome (FAS), also known as congestive myelopathy due to spinal vascular malformations, presents with paraplegia, sensory disturbance of lower limbs, and dysfunction of the bladder and rectum. Although FAS is characterized by a subacute onset of neurological symptoms that may wax and wane over a few years, the progression mechanism remains unclear. We report a case of FAS due to an angiographically occult arteriovenous fistula (AVF) that was diagnosed by an open surgical biopsy and intraoperative indocyanine green (ICG) angiography.

Anti-NMDAR encephalitis: case report and diagnostic issues.

[Transient charles bonnet syndrome after excision of a right occipital meningioma: a case report].

Charles Bonnet syndrome is a condition characterized by visual hallucinations. These simple or complex visual hallucinations are more common in elderly individuals with impaired peripheral vision. The current report describes a case of transient Charles Bonnet syndrome appearing after the removal of a meningioma.

Prediction of blood culture results by measuring procalcitonin levels and other inflammatory biomarkers.

Background: It would be helpful if we could predict positive or negative blood culture results. This study considered the usefulness of measuring procalcitonin (PCT) level and standard clinical biomarkers such as white blood cell (WBC) count, C-reactive protein (CRP) level, and platelet (PLT) count to predict blood culture results.

Method: We retrospectively analyzed the data from 422 specimens collected at our emergency center within the preceding 36 consecutive months.

Extensive deamidation at asparagine residue 279 accounts for weak immunoreactivity of tau with RD4 antibody in Alzheimer's disease brain.

Background: Intracytoplasmic inclusions composed of filamentous tau proteins are defining characteristics of neurodegenerative tauopathies, but it remains unclear why different tau isoforms accumulate in different diseases and how they induce abnormal filamentous structures and pathologies. Two tau isoform-specific antibodies, RD3 and RD4, are widely used for immunohistochemical and biochemical studies of tau species in diseased brains.

Results: Here, we show that extensive irreversible post-translational deamidation takes place at asparagine residue 279 (N279) in the RD4 epitope of tau in Alzheimer's disease (AD), but not corticobasal degeneration (CBD) or progressive supranuclear palsy (PSP), and this modification abrogates the immunoreactivity to RD4.

Long-term follow-up of growth hormone-producing pituitary carcinoma with multiple spinal metastases following multiple surgeries: case report.

This report describes a rare case of a patient with growth hormone (GH)-secreting pituitary adenoma with malignant transformation resulting in multiple metastases to the dura mater of the cerebral convexity and high cervical spine. The patient was a 60-year-old man with a previous history of pituitary adenoma with suprasellar extension who had undergone transsphenoidal surgery, craniotomy for a convexity tumor, and suboccipital craniotomy for a cerebellar tumor. Thirteen years after the initial surgery, suboccipital craniotomy for a cervicomedullary junction tumor and cervicospinal surgery for a metastatic tumor was performed.

Cerebellar hemorrhage secondary to cerebellopontine angle metastasis from thyroid papillary carcinoma.

A 63-year-old woman presented with a metastatic focus of papillary thyroid carcinoma in the cerebellopontine angle manifesting as lateral gazing nystagmus and slurred speech. Computed tomography demonstrated massive hemorrhage in the left cerebellar hemisphere. She was treated conservatively.

Biosynthetic conclusions from the functional dissection of oxygenases for biosynthesis of actinorhodin and related Streptomyces antibiotics.

Actinorhodin (ACT) produced by Streptomyces coelicolor A3(2) belongs to the benzoisochromanequinone (BIQ) class of antibiotics. ActVA-ORF5, a flavin-dependent monooxygenase (FMO) essential for ACT biosynthesis, forms a two-component enzyme system in combination with a flavin:NADH oxidoreductase, ActVB. The genes for homologous two-component FMOs are found in the biosynthetic gene clusters for two other BIQs, granaticin (GRA) and medermycin (MED), and a closely related antibiotic, alnumycin (ALN).

Clinical efficacy and safety of arbekacin sulfate in patients with MRSA sepsis or pneumonia: a multi-institutional study.

Arbekacin (ABK) is an aminoglycoside and widely used in Japan for treatment of patients infected with methicillin-resistant Staphylococcus aureus (MRSA). Although, ABK has concentration-dependent antibacterial activity, the peak serum concentration (C (peak)) of ABK has not yet been fully investigated as an indicator of the efficacy of ABK. The present study was conducted in patients admitted to hospitals affiliated with the ABK Dose Finding Study Group, between October 2008 and June 2011, who had pneumonia or sepsis, the cause of which was identified or suspected to be MRSA.

Thermoreversible gelation polymer as an embolic material for aneurysm treatment: a delivery device for dermal fibroblasts and basic fibroblast growing factor into experimental aneurysms in rats.

Background: This study evaluates whether thermoreversible gelation polymer (TGP) can be used as a delivery device to deploy dermal fibroblasts and cytokines into experimental aneurysms in rats.

Methods: The right common iliac artery of rats was surgically ligated and an experimental aneurysm was created by applying exogenous elastase. Seven days later, two aneurysms were harvested and used as controls (Group A), two were embolized with pure TGP (Group B), two were embolized with TGP and basic fibroblast growth factor (bFGF) (Group C) and two were embolized with TGP loaded with rat dermal fibroblasts (Group D).

Epitope determination of anti rat thy-1 monoclonal antibody that regulates neurite outgrowth.

Glycosylphosphatidylinositol-anchored protein Thy-1 is abundantly expressed on the cell surface of neurons and T lymphocytes in rodents. Although Thy-1 is known to bind integrins as a ligand and to mediate neurite outgrowth and immune responses, its precise function is not fully understood. Previously we produced several anti rat Thy-1 monoclonal antibodies and identified one, 2E11, which induces PC12 cell neurite outgrowth.
