Abstract
OBJECTIVES We previously reported, based on a multicenter randomized-control study, that the efficacy of intra-articular injections of hyaluronic acid (IA-HA) was not inferior to that of oral non-steroidal anti-inflammatory drugs (NSAIDs) in patients with knee osteoarthritis (OA). However, the molecular effects on the pathophysiology of knee OA remain unclear. C-terminal telopeptides of type II collagen (CTX-II) is reported to primarily originate from the interface between articular cartilage and subchondral bone, which is a site of potential remodeling in OA. We performed a predefined sub-analysis of the previous study to compare the changes of urinary CTX-II (uCTX-II) in response to IA-HA to those in response to NSAID for knee OA. DESIGN A total of 200 knee OA patients were registered from 20 hospitals and randomized to receive IA-HA (2,700 kDa HA, 5 times at 1-week intervals) or NSAID (loxoprofen sodium, 180 mg/day) for 5 weeks. The uCTX-II levels were measured before and after treatment. RESULTS The uCTX-II levels were significantly increased by IA-HA treatment (337.7 ± 193.8 to 370.7 ± 234.8 ng/μmol Cr) and were significantly reduced by NSAID treatment (423.2 ± 257.6 to 370.3 ± 250.9 ng/μmol Cr). The %changes of uCTX-II induced by IA-HA (11.6 ± 29.5%) and NSAID (-9.0 ± 26.7%) was significantly different (between-group difference: 20.6, 95% confidence intervals: 10.6 to 30.6). CONCLUSIONS While both IA-HA and NSAID improved symptoms of knee OA, uCTX-II levels were increased by IA-HA and reduced by NSAIDs treatment, suggesting these treatments may improve symptoms of knee OA through different modes of action.

Abstract
OBJECTIVE To assess which structural abnormalities on knee MRI are associated with development of osteophytes in middle-aged subjects without radiographic knee osteoarthritis. DESIGN We included subjects from the Osteoarthritis Initiative, aged 40-55 years, Kellgren & Lawrence grade 0 in both knees, and knee MRIs from both knees available at baseline, 24, 48 and 72 months. Structural exposures on MRI assessed using MOAKS included cartilage damage, bone marrow lesions, meniscal tear, meniscal extrusion, and Hoffa/effusion synovitis. We assessed whether each structural exposure was associated with the development of osteophytes on MRI in the medial and lateral tibiofemoral, and patellofemoral compartment. We estimated hazard ratios (HR) including 95% confidence intervals (CI) for osteophyte development using a mixed complementary log-log regression model adjusted for age, sex, and body mass index. RESULTS We included 680 knees from 340 subjects with a mean (SD) age of 50 years (3.0), and 51% men. In the medial tibiofemoral compartment, the absolute risk of osteophyte development in the first 24-month period was 4% in knees without, and 15% in knees with medial meniscal tear. Corresponding adjusted HR was 6.6 (95%CI = 3.4-12.9). In the lateral tibiofemoral compartment, the adjusted HR for developing osteophytes having a lateral meniscal tear was 3.3 (95%CI = 1.3-8.4). In the patellofemoral compartment, patellofemoral cartilage damage was most clearly associated with developing osteophytes (HR = 2.6, 95%CI = 1.8-3.7). CONCLUSIONS Meniscal tear seem to be the strongest structural risk factor for the development of tibiofemoral osteophytes, and patellofemoral cartilage damage for the development of patellofemoral osteophytes, respectively. Local biomechanical factors are important in early osteophyte development.

Abstract
Osseointegration of dental, craniofacial, and orthopedic implants is critical for their long-term success. Multifunctional surface treatment of implants was found to significantly improve cell adhesion and induce osteogenic differentiation of dental-derived stem cells in vitro. Moreover, local and sustained release of antibiotics via nanolayers from the surface of implants can present unparalleled therapeutic benefits in implant dentistry. Here, we present a layer-by-layer surface treatment of titanium implants capable of incorporating BMP-2-mimicking short peptides and gentamicin to improve their osseointegration and antibacterial features. Additionally, instead of conventional surface treatments, we employed polydopamine coating before layer-by-layer assembly to initiate the formation of the nanolayers on rough titanium surfaces. Cytocompatibility analysis demonstrated that modifying the titanium implant surface with layer-by-layer assembly did not have adverse effects on cellular viability. The implemented nanoscale coating provided sustained release of osteoinductive peptides with an antibacterial drug. The surface-functionalized implants showed successful osteogenic differentiation of periodontal ligament stem cells and antimicrobial activity in vitro and increased osseointegration in a rodent animal model 4 wk postsurgery as compared with untreated implants. Altogether, our in vitro and in vivo studies suggest that this approach can be extended to other dental and orthopedic implants since this surface functionalization showed improved osseointegration and an enhanced success rate.

Abstract
Pulmonary pleomorphic carcinoma is a rare malignant tumor that grows rapidly and has a poor prognosis. Although no effective treatments have so far been established, immune checkpoint inhibitors (ICIs) have shown clinical improvement in some cases of pleomorphic carcinoma. However, pseudoprogression is a major concern for treatment of this carcinoma using ICIs. Here, we report the case of a 61‐year‐old man who was diagnosed with large cell carcinoma of the lung with brain metastases. Systemic chemotherapy comprising carboplatin and pemetrexed was administered as a first‐line therapy; however, disease progression was observed. A tonsillar lesion grew rapidly after the administration of nivolumab as a second‐line therapy. Tracheostomy was planned to avoid suffocation, but the patient naturally expectorated the tumor. Pathological examination revealed that it was a palatine tonsillar metastasis of pulmonary pleomorphic carcinoma with infiltration of CD8+/CD4‐ lymphocytes and necrosis. The primary lesion expanded after nivolumab administration and shrank with no additional nivolumab administration. We therefore concluded that pseudoprogression caused expectoration of the tonsillar metastasis. Hence, ICIs can cause serious adverse events due to pseudoprogression.

Abstract
Here, we report a rare case involving a 66-year-old man with epidermal growth factor receptor (EGFR)-mutant lung adenocarcinoma and antisynthetase syndrome (ASS) treated with osimertinib. The patient presented with respiratory failure and bilateral pulmonary opacities; he was diagnosed with ASS accompanied by interstitial lung disease (ILD), consistent with paraneoplastic syndrome. After steroid pulse therapy, osimertinib was administered for lung adenocarcinoma without ILD exacerbation. Osimertinib could therefore be a treatment option for EGFR-mutant lung cancer with paraneoplastic ILD.

Abstract
Background Pirfenidone is an antifibrotic agent that is potentially effective for the treatment of idiopathic pulmonary fibrosis (IPF). However, no study has reported on its prophylactic value against chemotherapy‐associated acute IPF exacerbations when combined with chemotherapy for non‐small cell lung cancer (NSCLC). The present study assessed the safety and effectiveness of pirfenidone combined with carboplatin‐based chemotherapy or immune checkpoint inhibitors (ICIs) in patients with IPF and NSCLC. Methods A total of 14 patients with IPF and NSCLC who received treatment from 2013 to 2019 were included. Patients were treated with pirfenidone combined with carboplatin and nanoparticle albumin‐bound paclitaxel or S‐1 as first‐line chemotherapy. After confirming disease progression, patients received cytotoxic agents or ICIs, including nivolumab and pembrolizumab. Pirfenidone was continued regardless of chemotherapy changes. Overall survival (OS) and progression‐free survival (PFS) for lung cancer and IPF were calculated. Moreover, the cumulative incidence of acute exacerbation of IPF (AE‐IPF) within one year was evaluated. Results Median PFS for lung cancer was 110 days (95% confidence interval [CI]: 57–199 days), while the median OS was 362 days (95% CI: 220–526 days). Moreover, PFS for IPF was 447 days (95% CI: 286–indeterminate days), and the cumulative incidence of AE‐IPF within one year was 18%. Notably, none of the patients developed AE‐IPF associated with first‐line chemotherapy. Among the included patients, four received ICIs, none of whom developed ICI‐associated AE‐IPF. Conclusions The present study found that pirfenidone combined with carboplatin‐based regimens or ICIs might be safe first‐line chemotherapy for patients with IPF and NSCLC. Key points Significant findings of the study No patients with IPF and NSCLC who received pirfenidone in combination with first‐line carboplatin‐based chemotherapy or late‐line ICIs developed acute IPF exacerbations.
What this study addsPirfenidone might have a prophylactic effect against chemotherapy‐associated AE‐IPF.

Abstract
A 61-year-old woman with stage IVA lung adenocarcinoma exhibited high PD-L1 expression. Pembrolizumab was administered as second-line therapy. She developed destructive thyroiditis and her thyroid function started to decline during the administration of three to five courses. She was subsequently diagnosed with fulminant type 1 diabetes mellitus and ketoacidosis during the eighth course and insulin treatment was initiated. Pembrolizumab remained effective and was continued for 21 courses, even after the onset of diabetes mellitus. Immune-checkpoint inhibitor treatment can be continued with hormone replacement even after the development of type 1 diabetes mellitus as an immune-related adverse event.

Abstract
A 61-year-old man with squamous cell lung cancer was admitted to our hospital because of consciousness disturbance after treated with pembrolizumab. Cerebrospinal fluid examination revealed increased protein level (209.2 mg/dl) and lymphocytic pleocytosis(79/μl). He was diagnosed as a meningoencephalitis probably caused by an immune-related adverse event (irAE) of immune checkpoint inhibitors (ICIs), and was successfully treated with 1,000 mg methylprednisolone intravenously for 3 days twice and the consequent oral 1 mg/kg prednisolone. As ICIs, which activate the immune systems, are becoming important choices of the treatments against malignancies, we should keep the possibility of irAE in mind and, when needed, start the treatment as soon as possible.

Abstract
Basic-helix-loop-helix (bHLH) transcription factors play an important role in various organs' development; however, a tooth-specific bHLH factor has not been reported. In this study, we identified a novel tooth-specific bHLH transcription factor, which we named AmeloD, by screening a tooth germ complementary DNA (cDNA) library using a yeast 2-hybrid system. AmeloD was mapped onto the mouse chromosome 1q32. Phylogenetic analysis showed that AmeloD belongs to the achaete-scute complex-like ( ASCL) gene family and is a homologue of ASCL5. AmeloD was uniquely expressed in the inner enamel epithelium (IEE), but its expression was suppressed after IEE cell differentiation into ameloblasts. Furthermore, AmeloD expression showed an inverse expression pattern with the epithelial cell-specific cell-cell adhesion molecule E-cadherin in the dental epithelium. Overexpression of AmeloD in dental epithelial cell line CLDE cells resulted in E-cadherin suppression. We found that AmeloD bound to E-box cis-regulatory elements in the proximal promoter region of the E-cadherin gene. These results reveal that AmeloD functions as a suppressor of E-cadherin transcription in IEE cells. Our study demonstrated that AmeloD is a novel tooth-specific bHLH transcription factor that may regulate tooth development through the suppression of E-cadherin in IEE cells.

Abstract
Recently, the immune checkpoint inhibitor (ICI) pembrolizumab was demonstrated to be superior to platinum doublet chemotherapy in the first-line setting in patients with tumor programmed death-ligand 1 (PD-L1) expression of at least 50%. However, because patients with epidermal growth factor receptor (EGFR) mutations or anaplastic lymphoma kinase (ALK) rearrangements were not included in that study, the efficacy of pembrolizumab in lung cancers carrying EGFR mutations could not be determined. Here we describe two cases of response to pembrolizumab in EGFR mutated lung adenocarcinoma patients with PD-L1 overexpression. These cases indicate that ICI is an effective treatment for EGFR mutated lung adenocarcinoma patients with PD-L1 overexpression.

Abstract
Nivolumab is an anti‐PD‐1 blocking monoclonal antibody approved for the treatment of non‐small cell lung cancer (NSCLC). However, some patients on immunotherapy may experience rapid progression and worsening clinical status, known as hyperprogressive disease. We retrospectively reviewed the clinical records of patients with NSCLC administered nivolumab therapy at Toneyama National Hospital, Japan, from January 2016 to January 2018. Of the 87 patients administered nivolumab therapy, five experienced rapid progression during one cycle of nivolumab therapy. Four patients were treated with corticosteroids to overcome their symptomatic events. Nivolumab exhibited efficacy after temporal progression, so‐called “pseudoprogression”, in three patients, and their symptoms and laboratory results improved. In the other patient, pleural and pericardial effusions increased after nivolumab therapy, and drainage was required, with no subsequent recurrence. The clinical courses of our case series indicate that alternative treatment, namely high‐dose corticosteroids, antibiotics, and drainage, effectively treated the symptoms of rapid tumor progression. Of note, corticosteroids suppressed the temporary inflammatory reaction to nivolumab. Although hyperprogressive disease is thought to be associated with poor quality of life and survival, these treatment strategies may be useful in patients with expected responses to immunotherapy.

Abstract
BACKGROUND. The PD-1–blocking antibody nivolumab persists in patients several weeks after the last infusion. However, no study has systematically evaluated the maximum duration that the antibody persists on T cells or the association between this duration and residual therapeutic efficacy or potential adverse events. METHODS. To define the duration of binding and residual efficacy of nivolumab after discontinuation, we developed a simplified strategy for T cell monitoring and used it to analyze T cells from peripheral blood from 11 non–small cell lung cancer patients previously treated with nivolumab. To determine the suitability of our method for other applications, we compared transcriptome profiles between nivolumab-bound and nivolumab-unbound CD8 T cells. We also applied T cell monitoring in 2 nivolumab-treated patients who developed progressive lung tumors during long-term follow-up. RESULTS. Prolonged nivolumab binding was detected more than 20 weeks after the last infusion, regardless of the total number of nivolumab infusions (2–15 doses) or type of subsequent treatment, in 9 of the 11 cases in which long-term monitoring was possible. Ki-67 positivity, a proliferation marker, in T cells decreased in patients with progressive disease. Transcriptome profiling identified the signals regulating activation of nivolumab-bound T cells, which may contribute to nivolumab resistance. In 2 patients who restarted nivolumab, T cell proliferation markers exhibited the opposite trend and correlated with clinical response. CONCLUSIONS. Although only a few samples were analyzed, our strategy of monitoring both nivolumab binding and Ki-67 in T cells might help determine residual efficacy under various types of concurrent or subsequent treatment.

Abstract
OBJECTIVES The effectiveness of treatment after cessation of nivolumab in patients with advanced non-small cell lung cancer (NSCLC) has not been well investigated. The aim of the present study was to clarify the clinical benefit of post-nivolumab treatment in such patients. MATERIALS AND METHODS A retrospective review was conducted on patients who received treatment after cessation of nivolumab due to disease progression or adverse events at the Toneyama National Hospital between January 2016 and April 2017. RESULTS Among 64 patients treated with nivolumab, 26 patients received treatment after cessation of nivolumab due to disease progression (n = 21) or adverse events (n = 5). The median age of the patients was 68 years and 19 patients were male. Nineteen patients had performance status (PS) 1 or less at initiation of post-nivolumab treatment. Four, 20, and 2 patients were treated with platinum doublets, a single agent, and molecular targeting agents, respectively. Response rate, disease control rate, and median progression-free survival of first-line post-nivolumab treatment were 34.6% (9 patients), 73.1% (19 patients), and 2.8 months (95% confidence interval [CI]: 1.7-5.2), respectively. Adverse events (≥ grade 3) and treatment cessation were observed in 57.7% (15 patients) and 19.2% (5 patients), respectively. There were no statistically significant differences for the majority of patient characteristics between the groups with (n = 26) and without post-nivolumab treatment. However, PS at cessation of nivolumab and post-progression survival (PPS) after cessation of nivolumab (median PPS: 12.6 vs. 1.4 months, 95% CI: 3.8-14.7 vs. 0.4-2.2) were significantly different between the groups. A multivariate Cox regression analysis showed significant correlation of PS at cessation of nivolumab (hazard ratio [HR]: 0.34, 95% CI: 0.13-0.87) and post-nivolumab treatment (HR: 0.19, 95% CI: 0.08-0.43) with prolonged PPS after nivolumab. CONCLUSION Median post-progression survival in patients with advanced NSCLC who received post-nivolumab treatment was approximately 1 year.

Abstract
A 59-year-old woman suffering from dry cough and dyspnea was admitted to our hospital. She had undergone concurrent chemo-radiotherapy five months earlier. Chest computed tomography revealed bilateral ground-glass opacities extending outside the irradiated lung field. Her eosinophil numbers were increased in both the peripheral blood and the bronchoalveolar lavage fluid; therefore, she was diagnosed with radiation pneumonitis accompanied by eosinophilic alveolitis. Steroid therapy promptly improved the pneumonitis. Radiation pneumonitis accompanied by eosinophilic alveolitis extending outside the irradiated field is rare. Bronchoalveolar lavage is useful for a diagnosis, and steroid therapy is effective for treatment.

Abstract
Pleomorphic carcinoma (PC) of the lung is a rare type of non‐small cell lung cancer, exhibiting aggressive behavior and resistance to chemotherapy and radiotherapy. A previous study reported that PCs expressed high levels of PD‐L1, suggesting the potential efficacy of immune checkpoint inhibitors in these tumors. We retrospectively reviewed the clinical records of three patients with PC of the lung treated with nivolumab: a 59‐year‐old woman (Case 1), a 66‐year‐old man (Case 2), and an 83‐year‐old man (Case 3). PD‐L1 was highly expressed in their tumor cells. Two cases showed a partial response with long progression‐free survival. However, in Case 2, brain and bone metastases progressed during nivolumab treatment in spite of high PD‐L1 expression. This case series indicates that nivolumab is effective to some extent for PC of the lung. However, the clinical course of patients treated with nivolumab should be carefully observed, even when PD‐L1 is highly expressed.

Abstract
Nivolumab, an anti-programmed cell death-1 protein monoclonal antibody, is effective for treating patients with late-stage non-small-cell lung cancer. Immune checkpoint inhibitors such as nivolumab induce various kinds of immune-related adverse events, including vitiligo. Vitiligo has been reported in patients with melanoma but not lung cancer. We describe a 75-year-old man with lung adenocarcinoma, stage 4 with pleural and pericardial effusion, that progressed after first-line chemotherapy. Subsequently, he was treated with nivolumab as second-line therapy. After 6days of administering nivolumab, he developed vitiligo suddenly on the trunk of his body. Except for vitiligo, his physical examination was normal, and treatment with nivolumab was well tolerated. Therefore, this treatment was continued without further development or expansion of vitiligo. A computed tomography scan showed a reduction in the size of the lung nodule and stabilization of the pleural and pericardial effusion. This is the first case of vitiligo associated with the use of nivolumab in a patient with lung adenocarcinoma.

Abstract
We report a case of a 65-year-old woman with stage IV lung adenocarcinoma who experienced Stevens-Johnson syndrome (SJS) during afatinib therapy. The patient received afatinib as the first-line therapy after the confirmation of harboring an exon 19 deletion mutation in the epidermal growth factor receptor (EGFR) gene. The patient presented with multiple erythematous papules mainly on the body trunk and thigh 32 days after afatinib administration. Subsequently, diffuse erosions of oral mucosa and purpuric macules with flat atypical targets emerged. Skin biopsy specimen showed the histology compatible with epidermal necrosis and the patient was diagnosed as having SJS. The symptoms of SJS were recovered by systemic steroid and immunoglobulin treatment. Gefitinib was administered as the third-line therapy after the second-line therapy with carboplatin plus pemetrexed had failed. Tumor shrinkage was obtained shortly and has been maintained without the recurrence of SJS. Rechallenge of tyrosine kinase inhibitor by gefitinib could be an alternative treatment option in patients who experienced SJS by afatinib.

Abstract
OBJECTIVE The aim of this study was to examine the osteoarthritis (OA)-related structural changes associated with histological synovitis in end-stage knee OA patients. METHODS Forty end-stage knee OA patients (female: 88%, mean age: 71.8 y) were enrolled. All participants underwent 3.0-T MRI. The structural changes, such as cartilage morphology, subchondral bone marrow lesion (BML), subchondral bone cyst (SBC), subchondral bone attrition (SBA), osteophytes, meniscal lesion and synovitis, were scored using the whole-organ MRI scoring (WORMS) method. Synovial samples were obtained from five regions of interest (ROIs) of the knee joint during total joint replacement surgery. The associations between the histological synovitis score (HSS) and WORMS or the synovial expression levels of cyclooxygenase (COX)-2, interleukin (IL)-1β, IL-6 and transforming growth factor (TGF)-β were examined using Spearman's correlation coefficient. RESULTS Among the seven OA-related structural changes, the BML, SBC, SBA and synovitis were significantly associated with the HSS (r = 0.33, 0.35, 0.48 and 0.36, respectively), while other morphological changes were not. Although synovial COX-2, IL-1β or IL-6 expression levels were not associated with the HSS, the synovial TGF-β expression levels were associated with the HSS. CONCLUSION The presence of BML, SBC and SBA was associated with histological synovitis in end-stage knee OA patients.

Abstract
OBJECTIVE To evaluate the risk of radiation pneumonitis (RP) after stereotactic radiotherapy (SBRT) for patients presenting with severe pulmonary emphysema. METHODS This study included 40 patients with Stage I non-small-cell lung cancer who underwent SBRT, 75 Gy given in 30 fractions, at the Tokyo Medical University, Tokyo, Japan, between February 2010 and February 2013. The median age of the patients was 79 years (range, 49-90 years), and the male:female ratio was 24:16. There were 20 T1 and 20 T2 tumours. 17 patients had emphysema, 6 had slight interstitial changes on CT images and the remaining 17 had no underlying lung disease. The level of emphysema was classified into three groups according to the modified Goddard's criteria (severe: three patients, moderate: eight patients and mild: six patients). Changes in the irradiated lung following SBRT were evaluated by CT. RESULTS On CT images, RP was detected in 34 (85%) patients, and not in 6 (15%) patients, during a median observation period of 313 days. Of the six patients, three had severe emphysema and three had no underlying lung disease. Patients with severe emphysema had lower risk of RP than those with moderate emphysema (p = 0.01), mild emphysema (p = 0.04) and no underlying lung disease (p = 0.01). CONCLUSION Patients with severe emphysema had a low risk of RP following SBRT. ADVANCES IN KNOWLEDGE Little is known about the association between RP and pulmonary emphysema. Patients with severe emphysema had lower risk of RP than those with no underlying lung disease.

Abstract
OBJECTIVE The aim of the present study was to examine whether the degenerative and morphological changes of articular cartilage in early stage knee osteoarthritis (OA) occurred equally for both femoral- and tibial- or patellar- articular cartilage using magnetic resonance imaging (MRI)-based analyses. DESIGN This cross-sectional study was approved by the ethics committee of our university. Fifty patients with early stage painful knee OA were enrolled. The patients underwent 3.0 T MRI on the affected knee joint. Healthy volunteers who did not show MRI-based OA changes were also recruited as controls (n = 19). The degenerative changes of the articular cartilage were quantified by a T2 mapping analysis, and any structural changes were conducted using Whole Organ Magnetic Resonance Imaging Score (WORMS) technique. RESULTS All patients showed MRI-detected OA morphological changes. The T2 values of femoral condyle (FC) (P < 0.0001) and groove (P = 0.0001) in patients with early stage knee OA were significantly increased in comparison to those in the control, while no significant differences in the T2 values of patellar and tibial plateau (TP) were observed between the patients and the control. The WORMS cartilage and osteophyte scores of the femoral articular cartilage were significantly higher than those in the patellar- (P = 0.001 and P = 0.007, respectively) and tibial- (P = 0.0001 and P < 0.0001, respectively) articular cartilage in the patients with early stage knee OA. CONCLUSIONS The degradation and destruction of the femoral articular cartilage demonstrated a greater degree of deterioration than those of the tibial- and patellar- articular cartilage in patients with early stage knee OA.

Abstract
OBJECTIVES Knee osteoarthritis (OA) pain is suggested to be associated with inflammation and detrimental mechanical loading across the joint. In this cross-sectional study, we simultaneously examined the inflammation and alignment of the lower limb and examined how the pain components varied depending on the disease progression. DESIGN One-hundred sixty female medial type of early- [n = 74 in Kellgren-Lawrence (K/L) 2] to advanced-stage (n = 96 in K/L >2) knee OA subjects (70.5 years on average) were enrolled. Knee pain was evaluated using a pain visual analog scale (VAS) and the pain-related subcategory of the Japanese Knee Osteoarthritis Measure (JKOM-pain). The serum interleukin (sIL)-6 level reflecting synovitis, and the high sensitivity C-reactive protein (hs-CRP) level were measured to evaluate the severity of inflammation. The anatomical axis angle (AAA) was measured as an alignment index. The β-coefficient was estimated after adjusting for age and the body mass index (BMI) using a multiple linear regression analysis. RESULTS Multiple linear regression analyses showed that the sIL-6 levels, but not AAA, associated with the pain VAS [β = 10.77 (95% confidence interval (CI): 4.14-17.40), P < 0.01] and JKOM-pain scores [β = 3.19 (95% CI: 1.93-4.44), P < 0.001] in the early stage. Conversely, AAA, but not the sIL-6 levels, was found to be associated with the pain VAS [β = -1.29 (95% CI: -2.51 to -0.08), P < 0.05] and JKOM-pain scores [β = -0.49 (95% CI: -0.82 to -0.16), P < 0.01] in the advanced stage. CONCLUSIONS The presence of a higher level of sIL-6 and the varus alignment of the joint is associated with pain in early- and advanced-stage knee OA patients, respectively.

Abstract
The thenar motor units (MUs) were studied by the multichannel surface electromyography (EMG) technique. The median nerve was stimulated at the wrist by repetitive submaximal stimulation. Three hundred consecutive evoked responses were recorded from the thenar muscles of 5 healthy volunteers with a 32 channel matrix-type multielectrode. Seven channel F-wave waveforms in a selected electrode array were classified using a template-matching method. The F-wave parameters, amplitudes, latencies and muscle fiber conduction velocities (MFCVs), were calculated to evaluate the properties of single MU F-wave. Most of the F-waves (93.3%) were composed of a single motor unit action potential (MUAP). The numbers of MU classified from single MU F-waves in 5 subjects were 11, 8, 13, 13 and 13, respectively. Many of them (84.5%) were originated from the abductor pollicis brevis (APB), and there were a few MUs originated from the flexor pollicis brevis (FPB). Significant correlations were found between F-wave amplitudes and latencies in 3 subjects.

Abstract
A patient who had experienced an attack of transient global amnesia (TGA) was examined using neurophysiological methods. Magnetoencephalography (MEG) was performed and the Wechsler Memory Scale-Revised (WMS-R) test was administered at 5 days and at more than a month after the TGA episode. MEG data on neuronal activity obtained while the patient was undertaking a working memory task and during rest were analyzed using the wavelet-crosscorrelation method, which reveals time-lag and information flow between related sites in the brain. The WMS-R memory scores showed dramatic improvement when the test was administered a month following the attack, although no significant changes were observed in EEG, MRI and SPECT data. The MEG study revealed that under a working memory load how the neuron works functionally and the information propagates assembly within the right hemisphere, and that these brain functions were not performed adequately shortly after the TGA attack.

Abstract
Bone formation requires phosphate to calcify the osteoid produced by osteoblasts, Pit-1, a natrium-phosphate cotransporter, is expressed in osteoblasts and its expression levels are regulated developmentally and also by hormones and cytokines. Another type of phosphate transporter is expressed in osteoclasts and its function is required for bone resumption. These observations suggest that phosphate transport into the bone cells may play a role in regulation of bone formation and resorption in vivo and in the pathological situation in patients with bone diseases.

Abstract
Bone metabolism is regulated not only by the nutrition supplied by vessel but also by the signals from the cells in vascular tissues. Identification of such signaling molecules has been the major issue in the field of research on the relationship between bone and vasculatures. This review touches on the recent findings on the expression and functions of such signaling molecules including VEGF, MMP and non-collagenous bone matrix proteins.

Abstract
Periodical and long-term examination of the cardiac function is important for detecting early-stage disorders, and contributing to chronodiagnosis and chronotherapeutics. Frequent or daily examination utilizing the present test procedures, however, places the patient under stress even when it is administered at home and not during a hospital visit. In order to cope with this issue, monitoring systems whereby a patient is not aware of being examined were developed taking the electrocardiogram (ECG) as an example. The ECG was monitored while the patient was taking a bath or sleeping in bed. The system did not utilize any body surface electrodes but introduced in-water electrodes in the bath and textile electrodes on the bed. These systems made long-term observation feasible without imposing any stress on the patient.

Abstract
OBJECTIVE To evaluate in an animal model the haemostatic efficacy of vaporizing-cutting (VC) electrodes recently developed for use in high-energy transurethral resection of the prostate (TURP). MATERIALS AND METHODS Four VC electrodes were assessed for their haemostatic efficacy in the muscle and liver of pigs (in vitro) and dogs (in vivo). The devices tested were the roller-cutting and Vapor Cut (Karl Storz GmbH, Germany); the Wedge (Boston Scientific Corp., Boston, USA); and the Uroloop (Endocare Inc., Irvine, CA). In each the depth of the desiccated zone was compared with that produced by a standard cutting loop electrode. Each electrode was attached to a scanning system (developed previously) that allowed the electrode pressure on the tissue surface (in 3% sorbitol solution) and the running speed to be adjusted. The same generator was used with all devices. The tissue (muscle or liver) was cut by running the electrode over the surface at 200, 250 or 300 W, with the loop electrode used as the reference. After completing the procedure, the surgical wound and the surrounding tissue were dissected out and the depth of the heat-affected zone (HAZ, defined as the desiccated zone) measured. RESULTS In pig muscle (stroke speed 5 mm/s) there was no significant difference in the depth of the HAZ between the four VC electrodes and the loop, or among the VC electrodes at any of the power levels tested. In pig liver (stroke speed 5 mm/s), the roller cutting and Vapor Cut electrodes produced a thicker HAZ than the loop at all power levels tested (P < 0.01). The Wedge electrode produced a significantly thicker HAZ than the loop at 200 and 300 W (P < 0.01). There were no significant differences in HAZ among the VC electrodes at any power level. In dog muscle in vivo (stroke speed 10 mm/s), the roller cutting, Vapor Cut and Wedge electrodes produced a significantly thicker HAZ at 250 W than the loop at 150 W (the usual power for TURP) (P < 0.01). There was no significant difference among the VC electrodes. In dog liver in vivo (stroke speed 10 mm/s), the roller cutting electrode produced a significantly thicker HAZ at 250 W than the loop at 150 W (P < 0.01). CONCLUSIONS The present VC electrodes produced a thicker desiccation zone at higher powers (200-300 W) than the standard loop at the usual power (150 W). The four VC electrodes produced a similar desiccation zone. With pig muscle and liver in vitro, regular loops used at a higher power created a desiccation zone that was 70-80% of the depth created by the VC electrodes.

Abstract
Cycling on an ergometer is one effective means of measuring cardiovascular function while applying stress on the heart. Bathing in a hot water bath applies a low stress to the heart. The electrocardiograms of a healthy adult male (aged 35 at the start of study) were recorded while taking a hot water bath with no electrode attached to the body over a period of 2 years (376 days over a 762 day period). The recovery speed following the initial overshoot of the heart rate (HR) was observed. The bathtub was designed for the automatic acquisition of ECG data. Immediately after immersion in the tub, the HR reached a peak within 20 s and then exponentially decreased toward the lowest rate in the 120 s of bathing. The initial recovery speed of the HR from the stress of bathing had a specific rhythm in the subject. Spectrum analysis of the speed series indicated that slow recovery speed appeared in cyclic periods of approximately 1 year, 42 days and 17 days. The methodology may provide a chronodiagnostic index of an exercise test for cardiovascular function.

Abstract
OBJECTIVE Des-gamma-carboxy prothrombin (DCP), also called protein induced by vitamin K absence or antagonist II (PIVKA-II), is a tumor marker complementary to AFP for the diagnosis of hepatocellular carcinoma (HCC). Currently available immunoassays for DCP are not sensitive enough to detect HCC at an early stage. Recently, two new immunoassays with enhanced sensitivity were developed. The aim of this study was to assess the diagnostic values of the new methods in patients with small-sized HCC. METHODS Coded serum samples obtained from 36 patients with small-sized and single-nodular HCC (< or = 3 cm in diameter) and 49 patients with posthepatitic cirrhosis not carrying HCC were analyzed. DCP levels were determined in three different ways: 1) conventional EIA; 2) a new immunoassay using the electrochemiluminescence (ECLIA) detection system; and 3) a new immunoradiometric assay (IRMA). Lectin-reactive profiles of AFP (AFP-L3) were also determined. RESULTS In 36 patients with small-sized HCC, the rates of abnormal values obtained by the conventional, ECLIA, and IRMA methods were 2.7%, 27.8%, and 16.7%, respectively. An ROC analysis of the two new methods (ECLIA vs IRMA) revealed a better performance by the ECLIA method (p < 0.05). The true positive rate of AFP-L3 was 22.2%, whereas a combination assay of ECLIA for DCP and AFP-L3 resulted in a 41.7% sensitivity with a specificity of 90%. CONCLUSIONS Compared with the conventional method, the sensitivity in detecting small-sized HCC was increased in the two new DCP immunoassays (ECLIA and IRMA). The overall performance as evaluated by an ROC analysis was significantly better in ECLIA than in IRMA.

Abstract
A system for medical informatics education for medical students has been developed in the medical school. This paper describes the concept underlying the development of this system and its progressive outcomes over 8 years. In order to stimulate students to acquire computer-related knowledge and skills, this subject has been integrated into the course works of various medical subjects such as physiology. In addition, acquired knowledge and skills are evaluated within each subject by the production of reports for example, using computers. This provides a concrete example for students of the relevance of the information sciences to the solving of medical problems. A well equipped computer facility for the study of medicine also plays a significant role in inspiring student incentive. A computer room equipped with Macintosh computers was opened adjacent to the main medical library and is used in the same manner as the library, with books replaced by computers. In addition, all new students acquire their own Macintosh PowerBook. These various initiations have facilitated concept that the computer may be applied to medical problem solving at any time or place and may become as commonplace as a pen in daily medical practice.

Abstract
The soluble cytokeratin 19 fragment (CYFRA) and pro-gastrin-releasing peptide (ProGRP) are recently described promising tumor markers for lung cancers. To assess their alterations in renal dysfunction, serum levels of CYFRA and ProGRP were determined together with conventional markers including carcinoembryonic antigen (CEA), squamous cell carcinoma antigen (SCC), neuron specific enolase (NSE) in patients with renal failure of varying degrees. The mean concentration of all these markers but NSE significantly increased with the severity of renal failure. After hemodialysis (HD), the mean concentration of ProGRP, the molecular weight of which is comparable to that of 2-microglobulin, was significantly decreased. High false positive rates for tumor markers of lung cancer in patients with renal failure should be considered to avoid unnecessary diagnostic procedures.

Abstract
An automated system is developed to monitor cardiopulmonary functions during sleep using electrically conductive textiles. The system obviates the need to attach transducers or electrodes to the body surface, and the subject can follow his or her normal daily routine, wearing regular pajamas to bed. Part of the bed sheet consists of electrically conductive textiles under the positions of the head, torso and legs. Respiratory activity and electrocardiograms of diagnostic quality are observed by means of the electrodes while the subject is sleeping. Respiration is sensed by means of electrical capacitance in/around the thorax. Data acquisition and storage are fully automated; thus, the subject's awareness of being monitored is greatly reduced. This system could detect disorders of cardiopulmonary functions at an early stage, if used daily in the home with the concept of chronodiagnosis.

Abstract
BACKGROUND Surgical therapy for Benign Prostatic Hypertrophy (B.P.H.) has mainly depended upon Transurethral Resection of the Prostate (TUR-P) using a cutting loop electrode. Recently, a new technique TVP was reported using the VaporTrode apparatus. We assessed the safety and efficacy of the VaporTrode in a preliminary study. METHODS Histological changes of the muscle and liver of pigs were examined after vaporization using the VaporTrode and a cutting loop electrode. First, histological changes were investigated following vaporization after one stroke at a slow hand speed. Next, histological changes were assessed following vaporization at fixed stroke speed in an experimental model. RESULTS At an electrical output of less than 275 W, the depth of the vaporized layer increased as the stroke speed became slower (4.0 cm/s-2.5 cm/s). When the electrical output was 300 W, the depth of vaporized layer increased even at a faster stroke speed (2.5 cm/s-3.0 cm/s.) The depth of the desiccated layer increased as the stroke speed became slower at any electrical output. However, when the stroke speed was 4.0 cm/s, the depth of this layer was less than 2.0 mm. With the cutting loop electrode, the depth of the desiccated layer increased at a higher electrical power, but the change was very small. CONCLUSION To achieve deep enough vaporized and desiccated layers safely, the VaporTrode should be used at a stroke speed slower than 3.0 cm/s and a high electrical power of about 275 W.

Abstract
Patients with multi-infarct dementia often have periventricular low density lesions on computed tomography and periventricular hyper-intensity lesions on computed tomography and periventricular hyper-intensity lesions on magnetic resonance imaging. Hachinski called this condition leukoaraiosis and results of previous studies that in multi-infarct dementia leukoaraiosis correlates with cerebral hypoperfusion. Periventricular low-density lesions in the white matter also occur, but their origin and clinical significance insuch patients is unknown. We studied when these lesions develop in patients with Alzheimer's dementia, and whether their presence correlates with clinical findings and cerebral blood flow. The subjects were 37 patients with a probable diagnosis of Alzheimer's dementia, as based on the Neuroepidermilogy Branch of the National Institute of Neurological Disorders and Stroke and the Alzheimer's disease and Related Disorders Association system. Autopsy findings were also available for 2 patients. Patients at higher Functional Assessment Staging of Senile Dementia of Alzheimer Type stages had more extensive periventricular low-density lesions. Patients with the lesions were more likely to have grasp reflex and sucking relex. Blood flow to the frontal and parietal cortices was significantly less in patients with the lesions than in those without the lesions. Neither of the 2 autopsies cases yielded evidence of arteriolosclerosis. Periventricular low-density lesions in Alzheimer's dementia may be closely associated with a degenerative process different from that seen in multi-infarct dementia.

Abstract
Current EIA for PIVKA-II is not sensitive enough to detect small Hepatocellular Carcinoma (HCC). In an attempt to increase the diagnostic threshold, the current EIA was modified in two different ways: 1) immunoreaction of PIVKA-II in the sample with its monoclonal antibody was carried out overnight at 5 degrees C instead of for two hours at room temperature (the overnight method), 2) Avidin-Biotin technique was used for the second reaction(the ABC method);and their diagnostic values were determined as compared with the current EIA(2hr method) in a total of 138 patients including 36 patients with HCC. In 27 patients with HCC(< 3 cm in diameter), the rates of abnormal values obtained by the 2hr-, the overnight- and the ABC method were 14.8, 25.9 and 29.6% respectively. False positive rates of these three methods in 69 patients with liver cirrhosis were 1.4, 8.6 and 22.9% respectively. Thus, these two modifications improved the sensitivity of the current EIA and the overnight method appears to be superior to the ABC method in terms of specificity and simplicity. This conclusion was confirmed by ROC analysis.

Abstract
OBJECTIVES Currently available enzyme immunoassays for des-gamma-carboxy prothrombin (DCP) are not sensitive enough to detect hepatocellular carcinoma (HCC) at an early stage. Therefore, the objectives of this study were to enhance the sensitivity of the currently available enzyme immunoassay (EIA) for DCP and to assess the diagnostic values of the new methods compared with those of alpha-fetoprotein (AFP) in patients with small-sized HCC. METHODS Coded serum samples obtained from a total of 128 patients with chronic liver diseases, including 27 patients with small-sized HCC, were analyzed. DCP levels were determined in three different ways: 1) conventional EIA, 2) the overnight method, similar to the conventional EIA but the first reaction (immunoreaction of DCP with the monoclonal antibody) was proceeded overnight, and 3) the avidin-biotin complex (ABC) method. RESULTS In 27 patients with HCC ( < or = 3 cm in diameter), the rates of abnormal values obtained by the conventional, the overnight, and the ABC methods were 14.8, 25.9, and 29.6%, respectively. The overnight and the ABC methods comparably increased the sensitivity, whereas the ABC method gave the highest false-positive value in patients with chronic liver diseases (cirrhosis and chronic hepatitis) without HCC. The negative predictive value was 84.9% when AFP and the overnight DCP assays were combined, whereas the true positive rate by the combination assay of the ABC method for DCP and AFP (cut-off level at 200 ng/ml) was 33.3%. CONCLUSIONS Two modifications of the conventional EIA for DCP comparably increased the sensitivity, but the overnight method may be of more practical value in terms of specificity and ease. The rate of detection of small-sized HCC by tumor markers alone, however, is not satisfactory even when the modified DCP and AFP measurements are combined.

We investigated a system by which an electrocardiogram can be obtained without the individual's awareness. The practice of this concept involves placing the electrodes in a bed set composed of electrically conductive textiles. Electrocardiograms were successfully obtained during sleep. However, during the periods of subject's movement in bed, the waveform became unrecognizable.

Abstract
A 59-year-old woman was admitted to our hospital with acute onset of chest pain. She had experienced high fever, weight loss, polyarthralgia, myalgia, polyneuropathy and hallucinations for 3 years before admission. The diagnosis of polyarteritis nodosa with hepatitis B surface antigenemia was made by muscle biopsy and serological examinations, and administration of prednisolone induced remission of all the manifestations. After developing the acute attack of severe chest pain, she died suddenly. At autopsy, a DeBakey type 1 aortic dissection was found and the immediate cause of death was found to be cardiac tamponade secondary to rupture of the aortic dissection. Microscopically, necrotizing inflammatory lesions were present in the medium sized vascular arteries throughout her body. Furthermore, necrotizing vasculitis was also found in the vasa vasorum of the adventitia and media of the thoracic aorta. The dissecting lesion was seen in the outer layer of the media. Our results suggest that spontaneous dissection of the aorta may be attributed to necrotizing vasculitis of the vasa vasorum.

Abstract
To evaluate the relationship of 24 hour total heart beats (THB) or ventricular arrhythmias and cardiopulmonary function, 29 patients with Duchenne's muscular dystrophy (DMD) were studied using Holter electrocardiographic and echocardiographic recordings. The THB were 144,428 +/- 12,237 beats per 24 hours in the child group (8 to 15 years, n = 12) and 136,355 +/- 19,991 beats per 24 hours in the adult group (16 to 25 years, n = 17). The THB in the adult group significantly correlated well with % VC (r = -0.74), PaCO2 (r = 0.67), PaO2 (r = -0.59) and the respiration rate (r = 0.71), but not in the child group. In both groups, the echocardiographic parameters of the left ventricular size and function (left ventricular dimension, ejection fraction and D/S ratio) did not significantly correlate with the THB. Premature ventricular contractions (PVCs) were observed in 14 of the 29 patients (48.3%), and high risk PVCs (Lown's grade 3-4b) were observed in 11 of these 14 patients (78.6%). Echocardiographic parameters of the left ventricular function in the high risk PVC group were significantly deteriorated as compared with the low risk PVC group (Lown's grade 0-2) (p less than 0.02-p less than 0.001). We conclude that the THB in the adult group was mainly related to depressed pulmonary function, and the severity of the PVCs in both the adult and child groups was mainly related to the degree of left ventricular dysfunction.

Abstract
The mode and causes of myocardial hypertrophy occurring in association with ischemic heart disease were studied. The investigation involved autopsied hearts (15 cases of subendocardial infarction, 27 of transmural infarction, 20 of non-infarcted three vessel disease and 17 controls) and biopsied materials obtained during coronary-aorta bypass graft surgery (23 patients with angina pectoris and 46 with myocardial infarction). The subendocardial infarction group showed most marked myocardial hypertrophy that reflected extensive infarction and fibrosis, dilatation of the left ventricular cavity and the loss of myocytes. Despite a marked decrease in the number of myocyte layers, the residual myocardium of the left ventricle was uniformly hypertrophic, accompanied by an increase in the heart weight. The larger the area of fibrosis, the more marked was myocardial hypertrophy irrespective of the luminal diameter of the responsible coronary artery. These findings indicate that myocardial hypertrophy associated with ischemic heart disease is enhanced by the compensatory mechanisms for a decrease in the contractile myocardium due to fibrosis.

Abstract
Preventive diagnosis is important. Daily medical check-ups in the home which require little effort or practice on the patient's part could be one way to achieve this goal. We investigated the acquisition of electrocardiograms from a human subject in a regular bathtub. In order to prevent power line interference and base line drift due to body movements, an active notch filter and specially designed Ag/AgCl electrodes were utilised. The amplitude of the QRS complex obtained from the water (40 degrees C) was approximately 1/10 that of the direct body surface measurement. Increasing the electrical conductivity of the tap water by adding NaCl (0.2% in weight) resulted in a decrease in amplitude to 1/100 of the direct measurement. Otherwise, the waveform distortion was minimal. It was confirmed that acquisition of electrocardiograms of monitoring quality was feasible in a regular bathtub filled with ordinary tap water.
