Japanese General Clinical Oncologists' Knowledge and Real-world Experiences of Cancer Genomic Medicine: A Nationwide Web-based Survey Study.

Introduction: In Japan, insurance began covering two cancer gene panel tests in 2019. However, the availability of these tests remains limited to 247 facilities (as of October 2023). This survey-based study assessed the knowledge and recognition of cancer genomic medicine by physicians involved in cancer treatment.

Ataxia Telangiectasia in a Patient with Breast Cancer: A Case Report.

Ataxia telangiectasia (AT) is a rare autosomal recessive disorder caused by the pathological variants of the gene. Owing to i ts r arity a nd n ature, complications of AT, such a s malignant tumors, a re often difficult to manage with standard imaging studies and treatments, and there are no established management strategies. We report the case of a woman who had AT in childhood and developed breast cancer in her 20s; the disease was successfully managed by the decision-making of multidisciplinary physicians professionals with ethics support.

Multivariate analysis of the impact of weather and air pollution on emergency department visits for unprovoked seizure among children: A retrospective clinical observational study.

Background: An unprovoked seizure is a seizure or a cluster of seizures occurring within 24 h in a patient older than 1 month of age without precipitating factors. Recent studies have reported that extrinsic factors, such as meteorological conditions and air pollutants, may be important in seizure occurrence. Thus, this study aimed to examine the association between the number of visits to the emergency department (ED) by children for nighttime unprovoked seizures and exposure to multi-faceted factors, such as meteorological conditions and air pollution.

Clinical and molecular features of 66 patients with musculocontractural Ehlers-Danlos syndrome caused by pathogenic variants in (mcEDS-).

Background: Musculocontractural Ehlers-Danlos syndrome is caused by biallelic loss-of-function variants in (mcEDS-) or (mcEDS-). Although 48 patients in 33 families with mcEDS- have been reported, the spectrum of pathogenic variants, accurate prevalence of various manifestations and detailed natural history have not been systematically investigated.

Methods: We collected detailed and comprehensive clinical and molecular information regarding previously reported and newly identified patients with mcEDS- through international collaborations.

Impact of the State of Emergency during the COVID-19 Pandemic in 2020 on Asthma Exacerbations among Children in Kobe City, Japan.

The coronavirus disease (COVID-19) pandemic altered environmental factors. We studied the impact of these changes on asthma exacerbation (AE) by comparing the AE-related environmental factors between COVID-19 (2020) and pre-COVID-19 (2011-2019) eras. Between 2011 and 2020, 278,465 children (<16 years old) visited our emergency department, and 7476 were diagnosed with AE.

Epidemiological impact of universal varicella vaccination on consecutive emergency department visits for varicella and its economic impact among children in Kobe City, Japan.

Introduction: Previous studies reported a dramatic decline in the incidence of varicella and varicella-related deaths after implementing universal varicella vaccination (VarV). Although previous studies reported the effectiveness and economic impact of VarV, they were unknown in the emergency department (ED) setting.

Methods: To determine the effectiveness and economic impact of VarV in the ED, Kobe, Japan, we retrospectively reviewed the clinical database of consecutive patients younger than 16 years presenting to our primary ED from 2011 to 2019.

Multivariate analysis of the impact of weather and air pollution on emergency department visits for night-time headaches among children: retrospective, clinical observational study.

Objectives: To examine the association between the number of visits to the emergency department (ED) by children for night-time headaches and exposure to multifaceted factors, such as meteorological conditions and air pollution.

Design: We conducted a clinical observational time-series analysis study.

Setting: We reviewed consecutive patients younger than 16 years of age at the primary ED centre in Kobe city, Japan, during the night shift (19:30-7:00 hours) between 1 January 2011 and 31 December 2019.

Delineation of musculocontractural Ehlers-Danlos Syndrome caused by dermatan sulfate epimerase deficiency.

Background: Musculocontractural Ehlers-Danlos Syndrome (mcEDS) is a rare connective tissue disorder caused by biallelic loss-of-function variants in CHST14 (mcEDS-CHST14) or DSE (mcEDS-DSE), both of which result in defective dermatan sulfate biosynthesis. Forty-one patients with mcEDS-CHST14 and three patients with mcEDS-DSE have been described in the literature.

Methods: Clinical, molecular, and glycobiological findings in three additional patients with mcEDS-DSE were investigated.

Clinically diverse phenotypes and genotypes of patients with branchio-oto-renal syndrome.

Branchio-oto-renal (BOR) syndrome is a rare autosomal dominant disorder characterized by branchiogenic anomalies, hearing loss, and renal anomalies. The aim of this study was to reveal the clinical phenotypes and their causative genes in Japanese BOR patients. Patients clinically diagnosed with BOR syndrome were analyzed by direct sequencing, multiplex ligation-dependent probe amplification (MLPA), array-based comparative genomic hybridization (aCGH), and next-generation sequencing (NGS).

A pediatric patient with interstitial pneumonia due to enterovirus D68.

Enterovirus D68 (EV-D68) infection is associated with upper and lower respiratory tract symptoms such as fever, cough, and wheezing. Pediatric patients with EV-D68 infection easily develop more severe respiratory complications compared to patients infected with other species of enterovirus, and consequently, have a higher rate of hospitalization and admission to intensive care units. Therefore, the clinical picture of respiratory complications associated with EV-D68 infection needs to be elucidated.

Next-generation sequencing discloses a nonsense mutation in the dystrophin gene from long preserved dried umbilical cord and low-level somatic mosaicism in the proband mother.

Duchene muscular dystrophy (DMD) is a progressive muscle wasting disease, caused by mutations in the dystrophin (DMD) on the X chromosome. One-third of patients are estimated to have de novo mutations. To provide in-depth genetic counseling, the comprehensive identification of mutations is mandatory.
