An adult case of large defect of small mesenteric hiatal hernia causing small bowel obstruction.

Background: Small mesenteric hiatal hernias (SMHHs) are defined as a small group of internal hernias (IHs) that frequently diagnosed in children. However, SMHHs are relatively rare in adults. Bowel loop herniation via an abnormal mesenteric defect can lead to strangulated intestinal obstruction.

Effectiveness of inactivated influenza vaccine in children during the 2023/24 season: The first season after relaxation of intensive COVID-19 measures.

Background: The annual administration of the influenza vaccine is the most effective method for preventing influenza. We have evaluated the effectiveness of the inactivated influenza vaccine in children aged 6 months to 15 years across the seasons from 2013/2014 to 2022/2023. This study aims to investigate the effectiveness of the inactivated influenza vaccine in the 2023/2024 season, the first year following the easing of strict COVID-19 measures, and possibly the last season when only the inactivated vaccine is available on the market.

Long-term Outcome After Surgical Resection of Para-aortic Lymph Node Metastasis of Colorectal Cancer: A Multicenter Retrospective Study.

Background: The significance of resection of para-aortic lymph node metastasis in colorectal cancer is controversial.

Objective: To clarify the prognosis of colorectal cancer after para-aortic lymph node metastasis resection.

Design: Multicenter retrospective study.

Anterior Mobility of the Posterior Horn of the Lateral Meniscus Is Associated With Abnormal Magnetic Resonance Imaging Findings of Anteroinferior Popliteomeniscal Fascicle and Posterosuperior Popliteomeniscal Fascicle as Well as a Clinical History of Catching or Locking Symptoms.

Purpose: To identify predictors of anterior mobility of the posterior horn of the lateral meniscus (PHLM) among patient demographics (age, sex), clinical characteristics (a history of catching or locking symptoms [CLS], body mass index, alignment of limb), and magnetic resonance imaging (MRI) findings of 4 restraints: anteroinferior popliteomeniscal fascicle (aiPMF), posterosuperior popliteomeniscal fascicle (psPMF), posteroinferior popliteomeniscal fascicle (piPMF), and meniscofibular ligament (MFibL).

Methods: Between October 2010 and December 2014, patients who underwent arthroscopic measurement of mobility of the PHLM were identified. The Sakai classification was used to classify aiPMF and psPMF on MRI into the following 3 types: type A, the fascicle was depicted with obvious continuity and with a low-intensity band; type B, depicted with continuity but with an ambiguous intensity structure; and type C, depicted with discontinuity or not visible.

Profilin 2 isoform expression is associated with lung metastasis of colorectal cancer according to a comprehensive gene expression study using a mouse model.

Lung metastasis is the second most common type of metastasis in colorectal cancer. Specific treatments for lung metastasis have not been developed since the underlying mechanisms are poorly understood. The present study aimed to elucidate the molecular basis of lung metastasis in colorectal cancer.

Combined Comprehensive Risk Score of the Estimation of Physiologic Ability and Surgical Stress and C-Reactive Protein-to-Albumin Ratio Is a Strong Prognostic Indicator of Long-term Outcomes in Colorectal Cancer.

Background: In patients with colorectal cancer, both the C-reactive protein-to-albumin ratio and comprehensive risk score of the estimation of physiologic ability and surgical stress have demonstrated prognostic significance.

Objective: To assess the clinical value of the combined use of C-reactive protein-to-albumin ratio and comprehensive risk score for predicting prognosis in patients with colorectal cancer.

Design: Multicenter retrospective study.

Noonan syndrome-like phenotype associated with an ERF frameshift variant.

Noonan syndrome is a so-called "RASopathy," that is characterized by short stature, distinctive facial features, congenital heart defects, and developmental delay. Of individuals with a clinical diagnosis of Noonan syndrome, 80%-90% have pathogenic variants in the known genes implicated in the disorder, but the molecular mechanism is unknown in the remaining cases. Heterozygous pathogenic variants of ETS2 repressor factor (ERF), which functions as a repressor in the RAS/MAPK signaling pathway, cause syndromic craniosynostosis.

Effectiveness of Strategy-Focused Training in Colorectal Endoscopic Submucosal Dissection: A Retrospective Observational Study.

Background: Colorectal ESD, an advanced minimally invasive treatment, presents technical challenges, with globally varying training methods. We analyzed the learning curve of ESD training, emphasizing preoperative strategies, notably gravity traction, to guide ESD instructors and trainee programs.

Method: This retrospective study included 881 cases guided by an experienced supervisor.

Evaluating the Effectiveness and Clinical Outcomes of Endovascular Aneurysm Repair-First Approach for Ruptured Abdominal Aortic Aneurysm in Japan.

Purpose: To verify the validity of an endovascular aneurysm repair (EVAR)-first strategy for treating patients with ruptured abdominal aortic aneurysm (rAAA) in Japan.

Materials And Methods: This study was conducted on 2 groups of patients with rAAA who underwent surgical treatment at 3 hospitals in the Kanagawa Prefecture, Japan, between January 2007 and September 2016. The open surgical treatment group comprised patients with rAAA who underwent open surgical treatment before January 2012; their data were retrospectively collected from their medical records.

Reliability of Telepsychiatry Assessments Using the Attention-Deficit/Hyperactivity Disorder Rating Scale-IV for Children With Neurodevelopmental Disorders and Their Caregivers: Randomized Feasibility Study.

Background: Given the global shortage of child psychiatrists and barriers to specialized care, remote assessment is a promising alternative for diagnosing and managing attention-deficit/hyperactivity disorder (ADHD). However, only a few studies have validated the accuracy and acceptability of these remote methods.

Objective: This study aimed to test the agreement between remote and face-to-face assessments.

The Management of Direct Oral Anticoagulants for Colorectal Endoscopic Submucosal Dissection: A Multicenter Observational Study.

Background: There is a lack of reports on the use of direct oral anticoagulants (DOACs) during colorectal endoscopic submucosal dissection (ESD).

Aims: We aimed to assess whether the use of DOACs is associated with a higher incidence of delayed bleeding (DB) after ESD.

Methods: A total of 4175 colorectal neoplasms in 3515 patients were dissected at our hospitals during study period.

Papillary fibroelastoma originating from the atrial septum touching the mitral valve leading to infective endocarditis: a case report.

Background: Cardiac papillary fibroelastoma is a rare benign tumor, which is often mistaken for a vegetation. Predominantly asymptomatic, it can cause life-threatening complications. Although rare, mobile papillary fibroelastoma movement between affected valves may hamper valve closure and damage the valve, leading to valvular regurgitation.

Intravenous cyclophosphamide and immunoglobulin ameliorated visual field defects in a patient with eosinophilic granulomatosis with polyangiitis.

Treating ocular involvement in eosinophilic granulomatosis with polyangiitis (EGPA) can be challenging. We present the case of a 37-year-old woman with EGPA who had severe bilateral visual field defects. Laboratory results showed leukocytosis (17,500 WBC/μL, 25.

The efficacy and safety of intravenous immunoglobulin infusion in 12 h for the initial treatment of Kawasaki disease.

Background: Approximately 10-20 % of individuals develop a recrudescent or persistent fever after intravenous immunoglobulin (IVIG) infusion for the initial treatment of Kawasaki disease. The aim of this study was to evaluate the efficacy and safety of the initial IVIG treatment of Kawasaki disease based on duration of infusion.

Methods: This retrospective, single-center study included 53 patients with Kawasaki disease who were initially treated with 2 g/kg of IVIG by means of a single infusion from June 2018 to August 2019.

Pacemaker Relocation for Radiation Against Overlapping Lung Cancer.

We experienced a patient after pacemaker (PM) implantation who had lung cancer of the left upper lobe that developed just behind the PM. The patient was an 81-year-old man with many complications. Radiation was the only treatment option.
