[A Case of Subcutaneous Scrotal Metastasis from Primary Gastric Cancer].

Metastases to the subcutaneous scrotum are extremely rare. Here, we report a 78-year-old man who presented with pain to the scrotum and inguinal area. Two years ago, he underwent total gastrectomy for gastric cancer.

Insufficient Efficacy of Corpus Callosotomy for Epileptic Spasms With Biphasic Muscular Contractions.

Corpus callosotomy (CC) is the surgical strategy for drug-resistant epileptic seizures including epileptic spasms (ES). In this study we report a subtype of ES which is accompanied by two consecutive muscular contractions. This subtype has not been previously classified and may emerge via a complex epileptic network.

Efficacy and Safety of Epilepsy Surgery for Older Adult Patients with Refractory Epilepsy.

Purpose: The population of elderly patients with epilepsy has been growing rapidly and the chances of referring older patients with refractory epilepsy for surgical options could be increasing. In general, epilepsy surgery at higher ages has been less likely to be performed, because little is known regarding the risks and benefits in elderly patients. We, therefore, investigated surgical outcomes and comorbidities in a population ≥50 years old who underwent epilepsy surgery.

Estimation of Risk Factors for Head Slippage Using a Head Clamp System. A Retrospective Study.

Background: Although complications have been associated with head clamp systems, few reports have described head slippage. The present study aimed to determine risk factors for head slippage and speculated that the position of head holder pins might be associated.

Patients And Methods: We reviewed medical records and compared the positions of the pinned heads of patients on fused preoperative and postoperative computerized tomography (CT) images.

Comprehensive analysis of indels in whole-genome microsatellite regions and microsatellite instability across 21 cancer types.

Microsatellites are repeats of 1- to 6-bp units, and approximately 10 million microsatellites have been identified across the human genome. Microsatellites are vulnerable to DNA mismatch errors and have thus been used to detect cancers with mismatch repair deficiency. To reveal the mutational landscape of microsatellite repeat regions at the genome level, we analyzed approximately 20.

Epilepsy surgery reduced seizure frequency for patients with severe motor and intellectual disorders.

Introduction: Little is known about epilepsy surgery for patients with severe motor and intellectual disorders (SMIDs). We hypothesized that epilepsy surgery could reduce epileptic seizure frequency in these patients. The purpose of this study was to compare pre- and postoperative seizure frequency in patients with SMIDs.

Health-related quality of life in peripheral blood stem cell donors and bone marrow donors: a prospective study in Japan.

Understanding of the impact of stem cell donation on donors' health-related quality of life (HRQOL) remains limited. A prospective observational study of eligible unrelated donors enrolled in the Japan Marrow Donor Program was conducted to compare HRQOL and adverse events (AEs) between peripheral blood stem cell (PBSC) and bone marrow (BM) donors. In total, 107 PBSC donors and 108 BM donors were enrolled.

Classification of primary liver cancer with immunosuppression mechanisms and correlation with genomic alterations.

Background: The tumor microenvironment can be classified into immunologically active "inflamed" tumors and inactive "non-inflamed" tumors based on the infiltration of cytotoxic immune cells. Previous studies on liver cancer have reported a superior prognosis for inflamed tumors compared to non-inflamed tumors. However, liver cancer is highly heterogeneous immunologically and genetically, and a finer classification of the liver cancer microenvironment may improve our understanding of its immunological diversity and response to immune therapy.

Early Sirolimus Gel Treatment May Diminish Angiofibromas and Prevent Angiofibroma Recurrence in Children With Tuberous Sclerosis Complex.

Tuberous sclerosis complex (TSC) is a multisystem neurocutaneous disorder. Angiofibromas (AF), fibrous plaques, and hypopigmented macules are the major skin findings in TSC. Topical sirolimus reduces the volume and redness of AF and other skin findings.

Epstein-Barr Virus-Associated Post-Transplant Lymphoproliferative Disorders after Hematopoietic Stem Cell Transplantation: Pathogenesis, Risk Factors and Clinical Outcomes.

Epstein-Barr virus (EBV) is a ubiquitous virus belonging to the human -herpes virus subfamily. After primary infection, EBV maintains a life-long latent infection. A major concern is that EBV can cause a diverse range of neoplasms and autoimmune diseases.

Low incidence of posttransplant lymphoproliferative disorder after allogeneic stem cell transplantation in patients with lymphoma treated with rituximab.

Posttransplant lymphoproliferative disorder (PTLD) is a serious complication after hematopoietic stem cell transplantation (HSCT). Several studies of risk factors for PTLD have been reported; however, the probability of, and risk factors for, PTLD in patients with lymphoma is unknown. Japanese nationwide transplant registry data from 5270 patients with lymphoma after allogeneic HSCT were analyzed.

Feasibility of endoscopic submucosal dissection for colorectal neoplasia at anastomotic sites: a retrospective study.

Background: Metachronous colorectal lesions sometimes occur at anastomotic sites following colorectal surgery, which increases the risk of developing colorectal cancer. However, these lesions are difficult to treat even with minimally invasive methods such as endoscopic submucosal dissection (ESD). Thus, we aimed to evaluate the outcomes of ESD for colorectal lesions at anastomotic sites following colorectal surgery.

Complete closure versus simple closure for perforations during colorectal endoscopic submucosal dissection.

 The efficacy of complete closure versus simple closure for perforations during endoscopic submucosal dissection (ESD) has never been evaluated. We evaluated the efficacy of complete closure and simple closure for perforations and muscular layer injuries incurred during ESD. Thirty-four consecutive patients who underwent "complete closure" or "simple closure" for correction of perforations and muscular layer injuries during colorectal ESD were enrolled in this study.

Endoscopic suturing promotes healing of mucosal defects after gastric endoscopic submucosal dissection: endoscopic and histologic analyses in in vivo porcine models (with video).

Background And Aims: Endoscopic suturing of mucosal defects after endoscopic submucosal dissection (ESD) is expected to prevent postoperative adverse events. We aimed to endoscopically and histologically evaluate the healing process of post-ESD mucosal defects closed with endoscopic hand suturing (EHS) in in vivo porcine models.

Methods: Twelve mucosal defects (2 cm in size) were created in 2 pigs (6 defects per pig).

Symmetry of ictal slow waves may predict the outcomes of corpus callosotomy for epileptic spasms.

We aimed to analyse the ictal electrographic changes on scalp electroencephalography (EEG), focusing on high-voltage slow waves (HVSs) in children with epileptic spasms (ES) and tonic spasms (TS) and then identified factors associated with corpus callosotomy (CC) outcomes. We enrolled 17 patients with ES/TS who underwent CC before 20 years of age. Post-CC Engel's classification was as follows: I in 7 patients, II in 2, III in 4, and IV in 4.

Utility of Dual Red Imaging for Endoscopic Hemostasis of Gastric Ulcer Bleeding.

Dual red imaging (DRI; Red Dichromatic Imaging (RDI)) is a new type of image-enhanced endoscopy composed of two long wavelengths that together can visualize vessels in the deep submucosa of the gastrointestinal wall. We treated a case of gastric ulcer bleeding in which the bleeding point could be clearly visualized using DRI. A 71-year-old man who was taking warfarin for atrial fibrillation noticed tarry stool, entered a state of hypovolemic shock, and underwent emergency esophagogastroduodenoscopy.

Production of antifungal compounds by Bacillus spp. isolates and its capacity for controlling citrus black spot under field conditions.

Orange juice is a major agricultural product, and oranges are among the most widely sold fresh fruits in several countries. Citrus black spot (CBS), caused by the fungus Phyllosticta citricarpa, affects almost every species of citrus, causing a esthetic depreciation of the fruit and fruit drop, with consequent financial loss for its in natura commercialization. Fungicides are the major control measure for CBS, but have limited efficiency and high cost, and give rise to fungal strains resistant to these products.

[Successful treatment with lenalidomide-containing regimen of plasma cell leukemia accompanied by meningeal involvement].

The central nervous system (CNS) is rarely involved in plasma cell neoplasms (PCN), especially in patients with advanced disease, harboring poor prognostic chromosomal abnormalities. The prognosis after development of CNS is poor, with a median survival of 2-6 months. Here, we present a 56-year-old woman with isolated CNS relapse of plasma cell leukemia who was admitted to our hospital with back pain, thigh pain, and dysuria.

Easy anchoring and smaller skin incision procedure for neuronavigation-based frameless stereoelectroencephalography.

Epilepsy surgery uses both depth electrodes (DEs) and subdural electrodes (SE). DEs have mainly been developed and used in Europe. As we are able to use the DEs safely due to the current advanced level of technology, use of DEs has been increasing rapidly over the last decade.

Predictors of technical difficulty with duodenal ESD.

 Duodenal endoscopic submucosal dissection (ESD) is still considered technically challenging; however, few studies have objectively analyzed predictors of the technical difficulty. Therefore, the aim of the current study was to elucidate predictors of the technical difficulty of duodenal ESD.  This was a retrospective observational study.

Three Cases of Hemiconvulsion-Hemiplegia-Epilepsy Syndrome With Focal Cortical Dysplasia Type IIId.

Hemiconvulsion-hemiplegia-epilepsy syndrome (HHES) is a subset of acute encephalopathy characterized by infantile-onset with acute hemiconvulsive febrile status and subsequent unilateral cerebral atrophy and hemiparesis. In the chronic phase, patients with HHES develop epilepsy, typically displayed as intractable focal seizures. The patients are often intractable with antiepileptic drugs and need surgical treatment.

Higher serum testosterone levels predict poor prognosis in castration-resistant prostate cancer patients treated with docetaxel.

Background: The role of testosterone as a prognostic factor for castration-resistant prostate cancer treated with docetaxel in Japan was investigated.

Methods: A total of 164 patients with castration-resistant prostate cancer who received docetaxel treatment at Chiba University Hospital and an affiliated hospital were retrospectively analyzed. Testosterone and other clinical factors at the start of docetaxel treatment were evaluated with respect to overall survival and progression-free survival.
