Background: Long-term follow-up reports of low-grade endometrial stromal sarcoma (LGESS) including its clinical course and pathological data are rare. We previously reported the case of a Japanese woman diagnosed with LGESS, who was treated with multidisciplinary therapy. She had been suffering from uterine cervical tumor diagnosed as cervical polyps, or fibroid in statu nascendi, since 24 years old.

Background: Use of cast is a standard treatment (Tx) choice for early-onset scoliosis. Recently, toxicity from repetitive use of general anesthesia has received attention by the Food and Drug Administration (FDA). We introduce a nonanesthetized cast Tx protocol called alternatively-repetitive-cast-and-brace (ARCB) that we have used since 1995 and have conducted an extensive follow-up on these patients to verify the efficacy of this protocol.

Background: Early definitive spinal fusion (EF) has been widely recommended to avoid spinal deformity progression for early-onset scoliosis (EOS) with neurofibromatosis type 1 (NF-1). In contrast, growing rod (GR) procedure has recently been recommended for EOS associated with the dystrophic type NF-1. However, no studies have compared the surgical outcomes between EF and GR procedure for EOS with NF-1.

Recapitulating the human segmentation clock with pluripotent stem cells.

Nature

April 2020

Department of Cell Growth and Differentiation, Center for iPS Cell Research and Application (CiRA), Kyoto University, Kyoto, Japan.

Pluripotent stem cells are increasingly used to model different aspects of embryogenesis and organ formation. Despite recent advances in in vitro induction of major mesodermal lineages and cell types, experimental model systems that can recapitulate more complex features of human mesoderm development and patterning are largely missing. Here we used induced pluripotent stem cells for the stepwise in vitro induction of presomitic mesoderm and its derivatives to model distinct aspects of human somitogenesis.

Article Synopsis
  • - The study evaluated the effectiveness of the PillCam patency capsule (PPC) in assessing whether patients could safely undergo small bowel capsule endoscopy (SBCE) without risking retention due to stenosis.
  • - Out of 1,096 enrolled patients, 89.1% confirmed GI patency, with a very low SBCE retention rate of only 0.51% in those who had confirmed patency.
  • - Key factors linked to non-confirmation of patency included established Crohn's disease, imaging-detected stenosis, and certain clinical indicators like low serum albumin, highlighting the importance of accurate diagnosis for successful outcomes.

Simultaneous biplanar radiographic scanning technique (EOS) (EOS Imaging, Paris, France) variability has previously been evaluated for spinal parameters, however limited EOS data exist regarding accuracy of 3-dimensional (3D) rib cage reconstruction. The purpose of this study was to compare the evaluation of ribcage parameter between EOS 3D images and 3D computed tomography (CT) images from adolescent idiopathic scoliosis (AIS) patients, and validate the accuracy of EOS 3D ribcage reconstruction images. In total, 31 AIS patients (27 females, 4 males; mean age 14.

Background: Several authors mentioned surgical outcome for scoliosis associated with neurofibromatosis type 1 (NF-1). However, no studies have summarized long-term surgical outcomes after surgical treatment of early-onset scoliosis (EOS) with NF-1. The purpose of this study is to evaluate the long-term surgical outcome after early definitive spinal fusion for EOS in NF-1 patients.

Background: Postoperative shoulder imbalance (PSI) has a negative impact on the surgical outcomes of patients with adolescent idiopathic scoliosis. This study aimed to evaluate the risk factors of PSI in patients with Lenke type 5C curves.

Methods: This study included 100 patients who underwent posterior correction surgery using pedicle screw constructs for Lenke type 5C curves.

Aim: The cause of thrombocytopenia in patients with chronic hepatitis C virus (HCV) infection is multifactorial: hypersplenism, decreased thrombopoietin levels, and myelosuppression induced by HCV. Platelet counts increase after eradication of HCV; however, this mechanism is not fully understood. Therefore, the aim of this study was to determine the influence of these three factors on platelet counts.

Article Synopsis
  • Adolescent idiopathic scoliosis (AIS) is a common spinal deformity in children, with limited understanding of its genetic causes, prompting a study involving 79,211 Japanese individuals to identify new susceptibility loci.
  • The study discovered 20 loci associated with AIS, 14 of which were newly identified, accounting for 4.6% of the condition's phenotypic variance, and highlighted 21 related genes.
  • The research also revealed genetic links between AIS and factors like body mass index and uric acid, emphasizing the complex genetic backgrounds contributing to AIS.

Adolescent idiopathic scoliosis is the most ordinary pediatric spinal disease that causes a three-dimensional deformity. Early detection of this potentially progressive deformity is considered crucial. The purpose of the present study was to report the potential for accurately diagnosis of adolescent idiopathic scoliosis using a newly developed, automated, noninvasive asymmetry-recognition system for the surface of the human back using a three-dimensional depth sensor.

Article Synopsis
  • The study investigates the correlation between the elastic modulus (EM) of pancreatic tissue and the presence of branch-duct intraductal papillary-mucinous neoplasms (BD-IPMN).
  • A total of 183 normal pancreas samples and 123 BD-IPMN cases were analyzed, revealing significantly higher median elastic modulus in BD-IPMN cases (5.18 kPa) compared to normal samples (3.17 kPa).
  • The findings suggest that shear wave elastography (SW-EG) could serve as a useful diagnostic tool for identifying BD-IPMN, even in cases where cysts are not visible on traditional imaging.

Background: The incidence of mixed hepatitis C virus (HCV) genotype infection is variable, and a few reports exist regarding the efficacy of direct-acting antivirals (DAA) therapy for mixed genotype. We aimed to investigate the prevalence of mixed genotype and its impact on the virologic response to DAA therapy.

Methods: A total of 365 patients with chronic HCV infection who completed antiviral therapy were recruited.

Background: Congenital scoliosis (CS) is a common vertebral malformation. Spondylocostal dysostosis (SCD) is a rare skeletal dysplasia characterised by multiple vertebral malformations and rib anomalies. In a previous study, a compound heterozygosity for a null mutation and a risk haplotype composed by three single-nucleotide polymorphisms in have been reported as a disease-causing model of CS.

Background: Although corrective cast (CC) has been back in use for the treatment of early onset scoliosis (EOS), no studies have reported how clinically meaningful CC was in comparison with brace-only treatment (BT) in EOS. The aim of this study was to investigate the effect of CC treatment in terms of suppression of scoliosis progression before surgery.

Methods: This study was designed to conduct a comparison of patients treated at 2 spine institutions differing in treating methods (one: mainly CC with brace, the other: BT).

Background: We have yet to determine what types of lumbar degenerative changes can be observed on MRI in middle-aged adolescent idiopathic scoliosis (AIS) patients without undergoing surgery. The aims of this study were to investigate AIS patients who have reached middle age without undergoing surgery and to clarify if residual spinal deformities may have affected health-related quality of life (HRQOL) and lumbar spine degeneration.

Methods: Subjects comprised AIS patients who reached middle age without surgery and who underwent whole-spine X-rays, lumbar MRI, and SRS-22 surveys.

The optimal term of follow-up for patients who achieve sustained virological responses (SVR) is an important topic because of the widespread use of direct-acting antivirals (DAA), which achieve a high SVR rate. Investigations of long-term follow-up among patients with SVR after interferon (IFN) therapy have reported that approximately 80%-100% of patients maintained SVR. However, the long-term durability of SVR to DAA treatment is unknown.

A 69-year-old male was referred to our hospital after being diagnosed as having pericarditis with pericardial effusion. The symptoms of tamponade disappeared after the effusion was drained;although the cause of pericarditis remained unidentified. About 4 months later, the tamponade symptoms recurred due to the thickened nodular pericardium.
