Supramalleolar Lateral Opening-Wedge Osteotomy in Conjunction With Progressive Collapsing Foot Deformity Reconstruction for PCFD With Ankle Instability.

Background: Reconstruction of progressive collapsing foot deformity (PCFD) with ankle instability (PCFD class E) remains a substantial challenge to orthopaedic surgeons. We report the outcomes of PCFD class E treated by means of a relatively standard PCFD foot reconstruction approach with the addition of a supramalleolar lateral opening-wedge osteotomy.

Methods: We conducted a retrospective study of 13 patients (15 ankles) who underwent this procedure for PCFD class E between 2010 and 2021.

Optimization of the Revised Tokuhashi Scoring System: New Prognostic Criteria for Metastatic Spinal Tumor in Surgical Cases.

Introduction: The revised Tokuhashi scoring system has been used to predict survival in patients with metastatic spinal tumors. Because of the rapid progress of cancer therapy, the original criteria of the revised Tokuhashi scoring system became in recent years unsuitable. The study aim was to evaluate the validity of the revised Tokuhashi scoring system in patients who underwent spinal surgery and to establish new prognostic criteria.

Pulmonary Function Improves in Patients with Adolescent Idiopathic Scoliosis who Undergo Posterior Spinal Fusion Regardless of Thoracoplasty: A Mid-Term Follow-Up.

Introduction: The purpose of the present study was to determine, in a mid-term follow-up 5 years or more after surgery, the forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), and expiratory flow in patients with adolescent idiopathic scoliosis (AIS) who underwent posterior spinal fusion (PSF) with or without thoracoplasty.

Methods: The subjects were 134 patients with AIS who underwent PSF between 2004 and 2013. Forty-five patients agreed to participate in the study.

Anchor type at upper instrumented vertebra and postoperative shoulder imbalance in patients with Lenke type 1 adolescent idiopathic scoliosis.

Purpose: To clarify the impact of anchor type at upper instrumented vertebra (UIV) on postoperative shoulder imbalance in patients with Lenke type 1 adolescent idiopathic scoliosis (AIS) who underwent posterior spinal fusion.

Methods: Subjects were 81 patients with Lenke type 1 AIS who underwent posterior spinal fusion between 2004 and 2013. Twenty-five patients agreed to participate in the study.

Increase in pancreatic enzymes following spinal alignment changes in the thoracolumbar junction: Potential for acute pancreatitis after kyphosis correction.

Background: Despite the identification of various risk factors for pancreatitis and hyperamylasemia following spinal surgery, no report has investigated the relationship between spinal alignment changes and elevated serum amylase levels. The purpose of this study was to investigate the relationship between spinal alignment changes and hyperamylasemia after spinal fusion.

Methods: A total of 222 patients whose serum pancreatic amylase levels were measured before and after spinal surgery from December 2017 to May 2019 were included.

Assessment of Fall-Related Self-Efficacy: Characteristics that Influence the Perception of Patients with Chemotherapy-Induced Peripheral Neuropathy.

Objective: The present study aims to describe fall-related self-efficacy as perceived by patients with chemotherapy-induced peripheral neuropathy (CIPN). The characteristics of patients associated with low perceived self-efficacy of preventing falls were investigated.

Methods: A cross-sectional study of four hospitals in Japan.

Spinal Alignments of Residual Lumbar Curve Affect Disc Degeneration after Spinal Fusion in Patients with Adolescent Idiopathic Scoliosis: Follow-up after 5 or More Years.

Introduction: Despite preserving lumbar disc mobility, spinal sagittal, and/or coronal alignment might ultimately impede surgical success. The purpose of this study was to elucidate the effects of spinal alignment on lumbar disc degeneration after 5 or more years in adolescent idiopathic scoliosis (AIS) patients who underwent spinal fusion.

Methods: Subjects were 49 AIS patients who underwent posterior spinal fusion without lumbar curve fusion.

MRI evaluation of dural sac enlargement by interspinous process spacers in patients with lumbar spinal stenosis: Does it play a role in the long term?

Background: To investigate dural sac enlargements and spinal alignments in patients who underwent indirect decompression with interspinous spacers.

Methods: The subjects were 20 patients who underwent indirect decompression using an interspinous spacer (X-STOP) without laminectomy. Of these 20 patients, 1 patient underwent implant removal surgery 1 month after X-STOP surgery and two patients dropped out.

A Soup Service for Advanced Digestive Cancer Patients with Severe Anorexia in Palliative Care.

Background/aims: The palliative care team (PCT), nutrition support team (NST), and department of nutrition in our hospital developed a special soup service for patients with terminal cancer. We evaluated the usefulness of this soup service for improving the mood in patients with advanced digestive cancer with severe anorexia.

Material And Methods: We retrospectively reviewed the clinical data of 18 patients with advanced cancer originating in digestive organs who received soup service at our institution between 2015 and 2016.

Pulmonary function and thoracic deformities in adolescent idiopathic scoliosis 27 years or longer after spinal fusion with Harrington instrument.

Background: The aim of this study was to conduct an investigation into spinal fusion with Harrington instrument (HI) in patients with adolescent idiopathic scoliosis (AIS) and to survey pulmonary function and thoracic deformity outcomes many years after surgery.

Methods: Subjects comprised 194 patients diagnosed with AIS and treated with spinal fusion using HI between 1968 and 1987. Patients who gave their informed consent were subjected to a complete standing spine X-ray, chest CT, and pulmonary function tests.

Secretion of inflammatory factors from chondrocytes by layilin signaling.

Layilin (LAYN) is thought to be involved in reorganization of cytoskeleton structures, interacting with merlin, radixin, and talin. Also, LAYN is known to be one of the receptors for hyaluronic acid (HA). In rheumatoid arthritis (RA), inflammatory cytokines like tumor necrosis factor α (TNF-α) have been known to play pathological roles.

The immediate impact of the Fukushima Daiichi accident on local property values.

The Fukushima Daiichi accident released huge amounts of radioactive material over a wide area. We can appreciate the geographical extent of radioactive contamination from the information published online by the Japanese government. Historically, this is an unprecedented situation, which allows "natural experimentation" to estimate the causal effects of radioactive contamination on our society.

Nuclear power-related facilities and neighboring land price: a case study on the Mutsu-Ogawara region, Japan.

From the perspective of risk, nuclear-power-related facilities (NPRFs) are often regarded as locally undesirable land use. However, construction of NPRFs contributes to social infrastructural improvement and job creation in the host communities. This raises a question: How large are these positive and negative effects? To approach this question from an economic viewpoint, we estimated the hedonic land price function for the Mutsu-Ogawara region of Japan from 1976 to 2004 and analyzed year-by-year fluctuations in land prices around the NPRFs located there.
