Steroid-Responsive Involuntary Movements as a Remote Symptom of Febrile Infection-Related Epilepsy Syndrome.

Febrile infection-related epilepsy syndrome (FIRES) is a rare epileptic encephalopathy that occurs in children or adolescents. To date, evidence for the management of the post-acute phase of FIRES is focused on drug-resistant epilepsy that continues from the acute phase. Information on involuntary movements, which are newly developed in the chronic phase, is limited.

The Tumor Immune Microenvironment Is Associated With Recurrence in Early-Stage Lung Adenocarcinoma.

Introduction: Immune checkpoint inhibitors have recently been approved for the treatment of early-stage NSCLC in the perioperative setting on the basis of phase 3 trials. However, the characteristics of such patients who are susceptible to recurrence after adjuvant chemotherapy or who are likely to benefit from postoperative immunotherapy have remained unclear.

Methods: This biomarker study (WJOG12219LTR) was designed to evaluate cancer stem cell markers (CD44 and CD133), programmed death-ligand 1 (PD-L1) expression on tumor cells, CD8 expression on tumor-infiltrating lymphocytes, and tumor mutation burden in completely resected stage II to IIIA NSCLC with the use of archived DNA and tissue samples from the prospective WJOG4107 trial.

Therapeutic Strategies in Children with Epilepsy: A Quality-of-Life-Related Perspective.

Children with epilepsy are affected by several factors, including clinical and social variables. Among these variables, cognitive decline and behavioral disturbances, perceptions of stigma, and fatigue can lead to reductions in quality of life (QOL). Epileptic activities, including seizure severity, frequent seizures, and status epilepticus (SE), have been identified as important predictors of QOL.

Effect of Lacosamide on Interictal Epileptiform Discharges in Pediatric Patients With Newly Diagnosed Focal Epilepsy.

Background: The purpose of this study was to determine the efficacy of lacosamide (LCM) on interictal epileptiform discharges (IEDs) and evaluate the relationships between IEDs and seizure outcome in pediatric patients with focal epilepsy.

Methods: Patient inclusion criteria included (1) newly diagnosed focal epilepsy with unknown etiology; and (2) electroencephalogram recorded twice (before and after starting LCM) under the same conditions. The difference between the highest number of IEDs over five successive minutes (IEDs/5 min) and the location of IEDs was determined.

Factors associated with the development of epilepsy in very low birth weight infants.

Background: The survival rate of very low birth weight (VLBW) infants has recently improved. However, the occurrence of and factors associated with epilepsy in VLBW infants remain unknown. This study aimed to clarify the incidence, characteristics, and factors associated with epilepsy development in VLBW infants.

Successful treatment with atezolizumab combination chemotherapy in a patient with high-grade fetal adenocarcinoma of the lung: A case report.

High-grade fetal lung adenocarcinoma (H-FLAC) is a rare tumor, with little known of its response to chemotherapy with or without an immune checkpoint inhibitor or of its molecular profile. We report the first case of a 56-year-old man with stage IV H-FLAC who was successfully treated with carboplatin plus nab-paclitaxel in combination with atezolizumab. In addition, the tumor was found to be positive for amplification of the human epidermal growth factor receptor 2 gene.

Implication of changes in PD-L1 expression during neoadjuvant chemotherapy with docetaxel, cisplatin, and 5-fluorouracil (DCF) regimen in esophageal squamous cell carcinoma.

Background: Neoadjuvant docetaxel plus cisplatin and 5-FU (NAC-DCF) and adjuvant nivolumab monotherapy are the standard care for locally advanced resectable esophageal squamous cell carcinoma (ESCC). However, no effective biomarkers have been found in perioperative setting. We investigated how programmed death-ligand 1 (PD-L1) changes before and after NAC-DCF and how it relates to the therapeutic effect of NAC-DCF in resectable ESCC.

The Tumor Immune Microenvironment and Frameshift Neoantigen Load Determine Response to PD-L1 Blockade in Extensive-Stage SCLC.

Introduction: Despite a considerable benefit of adding immune checkpoint inhibitors (ICIs) to platinum-based chemotherapy for patients with extensive-stage SCLC (ES-SCLC), a durable response to ICIs occurs in only a small minority of such patients.

Methods: A total of 135 patients with ES-SCLC treated with chemotherapy either alone (chemo-cohort, n = 71) or together with an ICI (ICI combo-cohort, n = 64) was included in this retrospective study. Tumors were classified pathologically as inflamed or noninflamed on the basis of programmed death-ligand 1 expression and CD8 tumor-infiltrating lymphocyte density.

Yolk Sac Tumor in a Recurrence of Colonic Adenocarcinoma With Shared Mutations in and Genes: A Case Report.

Only four cases of colorectal adenocarcinoma with a yolk sac tumor (YST) component have been reported in the English literature. No genetic investigation has been performed in these cases. We report a case of colorectal adenocarcinoma in which the recurrent tumor had a YST component.

ACTH for epileptic spasms in Leigh syndrome with SLC19A3 mutation can induce status dystonicus.

Patients with Leigh syndrome (LS) sometimes develop epileptic spasms (ES). ACTH treatment for ES may be effective without serious adverse events in some patients with LS. Status dystonicus is a life-threatening disorder characterized by an acute exacerbation of generalized dystonia and often develops as a triggered event.

Efficacy of perampanel in epilepsy patients with autism spectrum disorder.

Aim: The aim of this study was to assess the usefulness of perampanel (PER), and to identify the relationship between behavioral impairments and electroencephalogram (EEG) findings in epilepsy patients with autism spectrum disorder (ASD).

Methods: Participants were ASD patients with epilepsy recruited between June 1, 2016 and June 30, 2018. Inclusion criteria were: seizures refractory to two appropriate antiseizure medications (ASMs); presence of neuropsychological impairments; and ≥12 months of monitoring.

Interstitial lung disease associated with capmatinib therapy in a patient with non-small cell lung cancer harboring a skipping mutation of MET exon 14.

Capmatinib is a MET tyrosine kinase inhibitor (TKI) that has recently been approved for the treatment of advanced non-small cell lung cancer (NSCLC) positive for skipping mutations of MET exon 14 (METex14). Drug-induced interstitial lung disease (ILD) is a relatively rare, but potentially serious, side effect of TKIs administered for lung cancer treatment. Here we report a case of capmatinib-induced ILD in a patient with NSCLC harboring a METex14 skipping mutation.

Clinically Mild Encephalopathy With a Reversible Splenial Lesion Type 2 Caused by Human Herpesvirus 6 Infection.

Background: Clinically mild encephalopathy with a reversible splenial lesion (MERS) is the second commonest cause of encephalopathy. Several pathogens have been detected in patients with MERS type 2, such as influenza A and B, but little is known about the proportion of cases of MERS type 2 with this pathogenesis. Human herpesvirus 6 (HHV6) is the second commonest pathogen causing acute encephalopathy.

Glucose transporter type 1 deficiency syndrome associated with autoantibodies to glutamate receptors.

Background: The clinical spectrum of glucose transporter type 1 deficiency syndrome (GLUT1DS) has broadened, with increasing recognition of a milder phenotype. Antibodies targeting the subunits of glutamate receptors (GluRs), including GluN1, GluN2B, and GluD2, have been detected in various neurological disorders. Anti-GluD2 antibodies in particular may be associated with cerebellar symptoms.

Effects of perampanel on secondary bilateral synchrony and behavioral problems in adolescents with epilepsy showing insufficient response with levetiracetam.

Purpose: The purpose of this study was to determine the efficacy of perampanel (PER) on secondary bilateral synchrony (SBS) and behavioral problems in adolescents with epilepsy who showed insufficient response to levetiracetam (LEV).

Methods: The primary criterion for patient selection was the presence of SBS. The criteria such as age between 12 and 18 years, seizures refractory to antiseizure medications including LEV, at least four seizures a month, neuropsychological impairments, and at least 12 months of follow-up also had to be fulfilled.

Thymic epithelial tumor treatment in Japan: analysis of hospital cancer registry and insurance claims data, 2012-2014.

Introduction: Thymic epithelial tumors are a rare type of neoplasm. Accordingly, it is difficult to perform phase III trials in patients with thymic epithelial tumors, and thus, no standard treatment has been established for these tumors. In this study, we aimed to investigate the current status of thymic epithelial tumor treatment in Japan.

The effect of the guidelines for management of febrile seizures 2015 on clinical practices: Nationwide survey in Japan.

Objective: To investigate the effect of guidelines for management of febrile seizures on the clinical practice, we conducted a nationwide survey in Japan.

Methods: The Japanese guidelines for management of febrile seizures 2015 (GL2015) was released in 2015. In 2016, a questionnaire was sent to all 512 certified hospitals (3 pediatricians each) of the Japan Pediatric Society and all 47 prefecture Pediatric Associations (10 private pediatricians each) in Japan asking about management policies for febrile seizures (FSs) during 2013-2014 and 2016.
