Impact of the severe acute respiratory syndrome coronavirus 2 pandemic on the incidence of type 1 diabetes mellitus in children in Yamanashi, Japan.

It has been hypothesized that the biopsychosocial stress associated with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, in combination with the immunological effects of SARS-CoV-2 and pancreatic β-cell dysfunction, may contribute to the onset of type 1 diabetes (T1D) in children. In this study, we documented the incidences of T1D in Yamanashi Prefecture, Japan, from 1986 to 2018, and expanded the analysis to include cases from 2019 to 2022 to evaluate the potential influence of coronavirus disease 2019 (COVID-19) on T1D incidence. The COVID-19 pandemic period was defined as 2020 to 2022.

Slowly progressive subtype of childhood-onset type 1 diabetes as a high-risk factor for end-stage renal disease: A cohort study in Japan.

Aim: To compare the incidence of end-stage renal disease (ESRD) between slowly progressive type 1 diabetes and acute-onset type 1 diabetes.

Methods: This cohort study enrolled all 521 patients with childhood-onset type 1 diabetes with the year of onset from 1959 to 1996 in Hokkaido Prefecture, Japan. We calculated the ESRD incidence rate per 100,000 person-years by sex, onset year, onset age, and type 1 diabetes subtype (slowly progressive or acute-onset).

Case report: A challenging case of mixed-variant myofibroblastoma with complex imaging and pathological diagnosis.

Myofibroblastomas are benign mesenchymal tumors that frequently occur in the groin. They show variable morphology, and the differential histopathological diagnoses are broad, including lipomatous to myxoid tumors. In addition, both pathological and imaging findings may be complex, which makes diagnosis challenging.

Correction: Mortality in childhood-onset type 1 diabetes mellitus with onset between 1959 and 1996: A population-based study in Hokkaido, Japan.

IgG4-related disease with subcutaneous involvement and the associated diagnostic challenges with MRI.

IgG4-related disease is a rare fibroinflammatory disorder characterized by the infiltration of IgG4-rich plasma cells. Herein, we report a case of IgG4-related disease of the subcutaneous tissue with atypical MRI findings and difficulties in the histopathological examination using needle biopsy. Based on the clinical presentation and MRI findings, the patient was diagnosed with a benign myxoid or cystic tumor.

Delayed Achilles Tendon Rupture at 17 Years of Age After Treatment of Clubfoot with Ponseti Method: A Case Report.

Case: Traumatic pediatric Achilles ruptures are rare, and few cases have been reported among patients with a history of Achilles tenotomy. A 17-year-old boy with a history of Achilles tenotomies for congenital clubfoot as an infant presented with acute midsubstance Achilles tendon rupture of the right leg. The gastrocnemius fascia was dissected to allow for approximation of the ruptured Achilles tendon segments.

Abnormality in re-programing of preparatory muscle activity for landing following unpredictable events in patients with anterior cruciate ligament injury.

Background: Anterior cruciate ligament deficiency (ACL-D) causes dysfunction in the quadriceps femoris muscle, and this dysfunction hampers a safe return to sports. However, how the dysfunctional quadriceps femoris muscle affects instantaneous re-programming of motor command in response to unpredictable events remains unknown. This study aimed to examine the effects of ACL-D on re-programming of preparatory muscle activity during an unpredictable landing task.

Impacts of Segond Fractures on Anterior Cruciate Ligament Reconstruction Outcomes.

Introduction: Segond fractures, characterized by avulsion injuries at the lateral tibial condyle's anterolateral structure (ALS) attachment, often coincide with anterior cruciate ligament (ACL) injuries, potentially leading to knee instability. However, the influence of Segond fractures on knee stability after ACL reconstruction remains uncertain. Despite documented ALS reconstructions, there is a lack of consensus regarding the assessment of ALS failure and the criteria for surgical interventions.

Mortality in childhood-onset type 1 diabetes mellitus with onset between 1959 and 1996: A population-based study in Hokkaido, Japan.

Aim: To examine the mortality rate and causes of death in childhood-onset type 1 diabetes in Japan.

Methods: For a median 36.7 years, we followed 391 patients under the age of 15 years who developed type 1 diabetes between 1959 and 1996.

Tactile stimulation restores inhibited stretch reflex attributable to attenuation of Ia afferents during surprise landing.

Arthrogenic muscle inhibition (AMI) is induced by pathological knee conditions. The present study aimed to investigate the effect of tactile stimulation on reflex changes induced by simulated AMI during unpredictable landing performances. Twenty participants performed six unilateral landing tasks: 15 cm normal landing (15NL), 30 cm normal landing (30NL), surprise landing (SL), 30 cm normal landing following vibration (30NLV), SL following vibration (SLV), and SL following vibration with Kinesiology tape (SLK).

Mother-child correlation of kidney function: data from the Yamanashi Adjunct Study of Japan Environment and Children's Study (JECS).

Background: Individual variation in kidney function can be affected by both congenital and acquired factors, and kidney function in children is possibly correlated with that in their mothers. However, the mother-child correlation in kidney function remains directly unconfirmed.

Methods: We conducted a cross-sectional study of 655 healthy pairs of 7- or 8-year-old children and their mothers as an adjunct study of a nationwide epidemiological study (Japan Environment and Children's Study).

Analysis of Health-Related Quality of Life and Clinical Evaluations in Patients with the Triad of Combined Knee Injuries.

Combined knee injuries of the anterior cruciate ligament (ACL), medial collateral ligament (MCL), and medial meniscus were called "the unhappy triad" in the past. With recent advances in diagnostic technology, combined ACL, MCL, and lateral meniscus injuries are now known to be the predominant triad. We examined and verified the treatment outcomes of the triad of combined knee injuries from both patient-based subjective evaluation and objective assessments.

Risk Factors for Long Bone Fractures in Patients with Severe Motor and Intellectual Disabilities: A 6-year Follow-up Retrospective Study.

Objectives: We investigated the clinical situation of fractures that occurred in patients in the severely disabled patients' ward of our hospital. The study aimed to identify risk factors for the occurrence of long bone fractures in the extremities, which pose problems in nursing care.

Methods: We retrospectively studied fractures that occurred between April 2015 and March 2021 among a total of 126 patients in the severely disabled patients' ward of our hospital.

Prevention Measures for COVID-19 and Changes in Kawasaki Disease Incidence.

Background: Kawasaki disease is suspected to be triggered by previous infection. The prevention measures for coronavirus disease 2019 (COVID-19) have reportedly reduced transmission of certain infectious diseases. Under these circumstances, the prevention measures for COVID-19 may reduce the incidence of Kawasaki disease.

Fetal biparietal diameter as a potential risk factor for prolonged second stage of labor: A retrospective observational cohort study.

Prolonged second stage of labor is a common abnormality of labor progression. Very little research exists regarding the relationship between prolonged second stage of labor and antepartum sonographic fetal head biometry parameters, especially fetal biparietal diameter (BPD). Fetal BPD assessment is essential for estimating fetal weight, and these measurements are readily available to Japanese obstetricians.

Improvement of locomotive syndrome after total hip arthroplasty: A two-year longitudinal cohort study.

Objectives: Patients requiring total hip arthroplasty (THA) may possibly have locomotive syndrome (LS). Therefore, we investigated changes of LS in patients undergoing THA and clarified key factors that affected LS stage.

Methods: A prospective cohort study was conducted with 88 patients undergoing THA (74 females, 14 males, mean age: 67.
