Abstract
Introduction Osimertinib may be effective in treating central nervous system (CNS) metastasis, but its efficacy in treating radiation therapy (RT)-naive metastasis is unclear. The OCEAN study assessed the efficacy of osimertinib against RT-naive CNS metastasis in patients previously treated (T790M cohort) and untreated patients (first-line cohort) with EGFR mutation. Here, we report the results of the first-line cohort. Methods Previously untreated patients with RT-naive CNS metastasis and EGFR mutation-positive NSCLC were treated with osimertinib. The brain metastasis response rate (BMRR), progression-free survival (PFS), and overall survival in the first-line cohort were secondary end points. Results A total of 26 patients were enrolled in the study between September 2019 and July 2020. The median age was 72.0 years with 80.8% female. There were 20 patients who had multiple CNS metastases. BMRR assessed by PAREXEL criteria was 76.9% (90% confidence interval [CI]: 63.3%-90.5%), BMRR assessed by Response Evaluation Criteria in Solid Tumors was 76.9% (95% CI: 54.0%-99.8%), and median PFS of CNS metastasis was 22.0 months (95% CI: 9.7 mo-not reached). The overall response rate was 64.0% (95% CI: 45.2%-82.8%), median PFS was 11.5 months (95% CI: 6.9 mo-not reached), and median survival time was 23.7 months (95% CI: 16.5 mo-not reached). Paronychia and increased creatinine level were the most frequent nonhematological toxicities observed in 13 patients (50%). Grade three and higher adverse events were less than 10%, and there were no treatment-related deaths. Pneumonitis was observed in five patients (19.2%). Conclusions These results suggest that osimertinib is effective in untreated patients with RT-naive asymptomatic CNS metastasis in a clinical practice first-line setting.

Abstract
BACKGROUND Dacomitinib significantly improves progression-free survival and overall survival (OS) compared with gefitinib in patients with non-small-cell lung cancer (NSCLC) harboring epidermal growth factor receptor (EGFR)-activating mutations. However, dacomitinib often causes skin toxicities, resulting in treatment discontinuation. We aimed to evaluate a prophylactic strategy for skin toxicity induced by dacomitinib. METHODS We performed a single-arm, prospective, open-label, multi-institutional phase II trial for comprehensive skin toxicity prophylaxis. Patients with NSCLC harboring EGFR-activating mutations were enrolled and received dacomitinib with comprehensive prophylaxis. The primary endpoint was the incidence of skin toxicity (Grade ≥2) in the initial 8 weeks. RESULTS In total, 41 Japanese patients participated between May 2019 and April 2021 from 14 institutions (median age 70 years; range: 32-83 years), 20 were male, and 36 had a performance status of 0-1. Nineteen patients had exon 19 deletions and L858R mutation. More than 90% of patients were perfectly compliant with prophylactic minocycline administration. Skin toxicities (Grade ≥2) occurred in 43.9% of patients (90% confidence interval [CI], 31.2%-56.7%). The most frequent skin toxicity was acneiform rash in 11 patients (26.8%), followed by paronychia in five patients (12.2%). Due to skin toxicities, eight patients (19.5%) received reduced doses of dacomitinib. The median progression-free survival was 6.8 months (95% CI, 4.0-8.6 months) and median OS was 21.6 months (95% CI, 17.0 months-not reached). CONCLUSION Although the prophylactic strategy was ineffective, the adherence to prophylactic medication was quite good. Patient education regarding prophylaxis is important and can lead to improved treatment continuity.

Abstract
BACKGROUND Osimertinib is one of the standard first-line treatments for advanced non-small cell lung cancer in patients with epidermal growth factor receptor (EGFR) mutations, because it achieves significantly longer progression-free survival (PFS) than conventional first-line treatments (hazard ratio: 0.46). However, the efficacy and safety of osimertinib as a first-line treatment for patients aged ≥75 years remain unclear. METHODS This phase II study was performed to prospectively investigate the efficacy and safety of osimertinib for elderly patients with EGFR mutation-positive advanced non-small cell lung cancer. The primary endpoint was 1-year PFS rate; secondary endpoints were overall response rate (ORR), PFS, overall survival (OS), and safety. RESULTS Thirty-eight patients were included in the analysis. The 1-year PFS rate was 59.4% (95% confidence interval [CI], 46.1%-72.7%), which did not meet the primary endpoint (the threshold 1-year PFS rate of 50% predicted using data from the NEJ003 study). The most common grade 3/4 adverse events were rash/dermatitis acneiform/ALT increased/hypokalemia (2 patients, 5%). Seven patients developed pneumonitis (17.5%). There were no other cases of treatment discontinuation due to adverse events other than pneumonitis. CONCLUSION Although this study did not meet the primary endpoint, osimertinib was tolerable for elderly patients with EGFR mutation-positive advanced non-small cell lung cancer.

Abstract
OBJECTIVES Nerve growth factor (NGF) and sensory nerves are key factors in established osteoarthritis (OA) knee pain. We investigated the time course of NGF expression and sensory nerve growth across early and late stages of OA progression in rat knees. DESIGN Knee OA was induced by medial meniscectomy in rats. OA histopathology, NGF expression, and calcitonin gene-related peptide immunoreactive (CGRP-IR) nerves were quantified pre-surgery and post-surgery at weeks 1, 2, 4 and 6. Pain-related behavior was evaluated using dynamic weight distribution and mechanical sensitivity of the hind paw. RESULTS NGF expression in chondrocytes increased from week 1 and remained elevated until the advanced stage. In synovium, NGF expression increased only in early stages, whereas in osteochondral channels and bone marrow, NGF expression increased in the later stages of OA progression. CGRP-IR nerve density in suprapatellar pouch peaked at week 4 and decreased at week 6, whereas in osteochondral channels and bone marrow, CGRP-IR innervation increased through week 6. Percent ipsilateral weight-bearing decreased throughout the OA time course, whereas reduced paw withdrawal thresholds were observed only in later stages. CONCLUSION During progression of knee OA, time-dependent alterations of NGF expression and CGRP-IR sensory innervation are knee tissue specific. NGF expression increased in early stages and decreased in advanced stage in the synovium but continued to increase in osteochondral channels and bone marrow. Increases in CGRP- IR sensory innervation followed increases in NGF expression, implicating that NGF is a key driver of articular nerve growth associated with OA pain.

Abstract
Background It has long been thought that small‐cell lung cancer (SCLC) is a central type of tumor that is located in the proximal bronchi and the mediastinum. However, several studies reported that SCLC exhibited several types of spread pattern on computed tomography (CT). The aim of this study is to investigate the relationship between CT images and clinical characteristics in patients with SCLC. Methods We retrospectively reviewed the CT images of 92 SCLC patients and classified them into six types of spreading patterns: central, peripheral, lymphangitic spread (LYM), pleural dissemination (PLE), lobar replacement (LOB), and air‐space consolidation (AC). We also evaluated the correlation between primary tumor location and the clinical characteristics of patients. Results The most common type of imaging pattern was peripheral (n = 40, 44%), with the next most common type being central (n = 27, 29%). Atypical types of SCLC, such as LYM (n = 2, 2%), PLE (n = 4, 4%), LOB (n = 8, 9%), and AC (n = 11, 12%), were also recognized in our study. The prevalence of emphysema and interstitial lung disease (ILD) was significantly higher in the peripheral type than in the central type (p = 0.0056 and p = 0.0403, respectively). Meanwhile, no survival difference was seen between the central type and the peripheral type (median months 17.9 vs. 21.9, respectively, p = 0.720). Conclusions The peripheral type of tumor was correlated with higher prevalence of emphysema and ILD in SCLC. Our result suggests different mechanisms of development and tumor characteristics according to tumor location.

Abstract
Edwardsiella tarda is an anaerobic, gram‐negative rod bacterium associated with freshwater and marine life. Human E. tarda infections are rare, and most infections in humans cause gastroenteritis. Extraintestinal infections of E. tarda such as pleural empyema are particularly rare. A 72‐year‐old man was admitted with cough and purulent sputum. His medical history included periodontal disease and gastric cancer for which he had undergone total gastrectomy. Chest computed tomography showed left pleural effusion with foci of gas, and both E. tarda and Streptococcus constellatus were cultured from the pleural effusion. Thus, he was diagnosed with gas‐forming empyema. He was successfully treated with therapeutic thoracentesis and antibiotics. Our case suggests that a dietary habit of raw fish, undernutrition, gastrectomy and oral infection may be predisposing factors for empyema caused by E. tarda.

Abstract
Although sedation for bronchoscopy improves patient comfort, there is a risk of oversedation in elderly patients. Only a few studies have evaluated the efficacy and safety of sedation for bronchoscopy in elderly patients.This study retrospectively analyzed records of 210 patients who underwent transbronchial brushing and/or biopsy under midazolam sedation at National Hospital Organization Omuta National Hospital between June 2017 and October 2019. Patients were administered 1 mg midazolam following 10 mL 4% lidocaine inhalation. When sedation was insufficient, 0.5 mg midazolam was administered additionally. Diagnostic yield, incidence of complications, amount of oxygen supplementation, decreases in percutaneous oxygen saturation (SpO2), changes in blood pressure, and degree of comfort were analyzed.Patients were divided into the elderly (n = 102) and non-elderly (n = 108) groups. No significant differences were observed in diagnostic yield and procedure time between the 2 groups, and no severe adverse events were noted in the elderly group. The degree of comfort during bronchoscopy was significantly higher in the elderly group. In patients administered < 2 mg midazolam, the amount of oxygen supplementation and decreases in SpO2 were significantly smaller in the elderly group compared to the non-elderly group.The risk of adverse events related to midazolam sedation in bronchoscopy does not increase with age, and sedation improves comfort during flexible bronchoscopy in elderly patients. Moreover, a total dose of midazolam <2 mg is safe for elderly patients undergoing bronchoscopy.

Abstract
OBJECTIVES Swallowing function is critical for continuing oral feeding to prevent frailty in older adults. In this study, we investigated the impact of tongue pressure and pulmonary function on the nutritional status of older adults. DESIGN, SETTING, PARTICIPANTS This cross-sectional study was conducted in Kitakyushu, Japan from August 2017 to November 2018. Fifty-two residents aged >65 years of age from three nursing care insurance facilities in Kitakyushu City, Japan were recruited. MEASUREMENTS Oral health status, swallowing function, nutritional status using a mini nutritional assessment short form (MNA-SF), cognitive function, activities of daily living, peak expiratory flow rate (PEFR) for pulmonary function, and tongue pressure were assessed. The associations between nutritional status and the above factors were analysed using a logistic regression model. RESULTS Participants were divided into two groups: well-nourished group (MNA-SF ≤12) and undernutrition group (MNA-SF <12). Multivariate logistic regression analysis revealed that the correlations of PEFR [odds ratio (OR) = 0.23, 95% confidence interval (CI) = 0.23-0.89 p=0.033) and tongue pressure (OR = 0.88, 95% CI = 0.88-0.99, p=0.029) remained significant even after adjustment with possible confounders. CONCLUSION Maximum tongue pressure and PEFR in older adults were significantly associated with their nutritional status. These findings suggest that maintaining oral and pulmonary function may be a preventive factor against a decrease in the nutritional status of older frail adults.

Abstract
Background and purpose Acute respiratory distress syndrome (ARDS) complication has long been considered a factor associated with poor prognosis in patients with miliary tuberculosis. However, few reports exist on the prognostic factors of miliary tuberculosis including those complicating ARDS. Subjects and methods We retrospectively examined prognoses and other clinical information obtained from medical records of a total of 68 patients diagnosed with miliary tuberculosis. Clinical findings were compared between patients who died within three months (non-survivor group) and those who survived beyond three months (survivor group), and risk factors for death within three months of diagnosis were examined using logistic regression analysis. Results Fifteen of 68 patients diagnosed with miliary tuberculosis died within three months. Most patients were aged 60 years or older (63 patients; 91.2%), with a peak in the 80 s (32 patients; 47.1%). Of the 68 patients with miliary tuberculosis, 13 (19%) had ARDS. The risk of death within three months increased with increasing age and ARDS onset during the disease course. The results of multivariate analysis revealed that, in addition to age (odd ratio (OR): 15.5) and the presence/absence of ARDS (OR: 12.0), consciousness disturbance (OR: 81.53) and high BUN levels (OR: 5.71) were independent factors for death within three months. Conclusion In patients with miliary tuberculosis, old age, ARDS, consciousness disturbance, and high BUN levels were factors associated with poor prognosis.

Abstract
BACKGROUND Accumulating evidence indicates that knee pain gives rise to sensory and motor alterations, however, whether different profile of knee pain causes different alterations has not been investigated. The purpose of this experimental study is to clarify characteristics of medial and lateral knee pain and its potential for modulating sensory and motor function in humans. METHODS Fourteen healthy men were included. Medial knee pain (MP) was induced by injection of hypertonic saline (0.5 mL) into the tibial insertion of the medial collateral ligament. For comparison, lateral knee pain (LP) was induced by injection of hypertonic saline identically into the iliotibial tract. Isotonic saline was injected contralaterally as control. Pain intensity was assessed on a continuous electronic visual analogue scale (VAS). Before, during and after the painful state, pressure pain thresholds from the knee (PPTs), maximal isometric muscle strength of the quadriceps and grip power were assessed bilaterally. RESULTS MP demonstrated significantly higher VAS scores than LP and compared with control. PPTs decreased on medial and lateral knee in MP but only on the lateral knee in LP. Quadriceps muscle strength and grip power reduced bilaterally in both models, however, MP caused significantly greater reduction of ipsilateral quadriceps strength compared with LP. CONCLUSION Medial knee pain has a greater impact on deep tissue hyperalgesia and reduction of the muscle strength compared with lateral knee pain. This is a novel finding that should be taken into consideration in a treatment strategy for painful knee patients. SIGNIFICANCE The experimental medial knee pain model demonstrated higher pain intensity, more localized pain distribution, widespread deep tissue hyperalgesia and more severe inhibition of muscle strength compared with the lateral knee pain model.

Abstract
Radiation is the treatment of choice for canine nasal tumours but, in almost all cases, there is local recurrence associated with poor prognosis. This report describes the effect of endoscopic photodynamic therapy using talaporfin sodium for canine intranasal carcinoma recurring after radiation therapy. Rhinoscopic photodynamic therapy was administered after radiation therapy in three dogs with recurrent intranasal carcinoma. Two to 24 illuminations of a 665-nm diode laser were performed two hours after intravenous bolus injection of 5·0 mg/kg of talaporfin sodium. Photodynamic therapy induced almost complete remission and prolonged survival time in all cases suggesting that it might be a useful treatment for intranasal carcinomas that recur after radiation.

Abstract
BACKGROUND The use of conditioning pain modulation (CPM) is hampered by poor reproducibility and lack of user-independent paradigms. This study refined the CPM paradigm by applying user-independent cuff algometry. METHODS In 20 subjects, the CPM effect of conditioning with cuff stimulation on the arm was investigated by pain test stimuli on the contralateral leg before and in parallel with different cuff conditionings (10, 30, 60 kPa/60 s; 30, 60 kPa/10 s). As test stimulus, another cuff was inflated (1 kPa/s) until the subjects detected the pain tolerance threshold (PTT) during which the pain detection threshold (PDT) and the pressure at a pain intensity of 6 cm on a 10-cm visual analogue scale (PVAS6) were extracted. For comparison, pressure pain thresholds (PPTs) as test stimuli were recorded by the user-dependent handheld pressure algometry. Combinations of cuff locations for conditioning (pain intensity standardized) and contralateral test stimuli were additionally evaluated (leg-arm, leg-leg, arm-thigh). The test-retest reliability in two sessions 1 month apart was assessed in five CPM protocols. RESULTS In all protocols, the PDT, PVAS6 and PTT increased during conditioning compared with baseline (p < 0.05). The CPM effect (i.e. conditioning minus baseline) for PVAS6, PTT and PPT increased for increasing conditioning intensities (p < 0.05). The CPM effects were not significantly different for changes in conditioning durations or conditioning/test stimulus locations. In two sessions, the CPM effects for PVAS6 and PTT assessed after 60 s of conditioning on the leg/thigh showed the highest intra-class correlations (0.47-0.73), where they were 0.04-0.6 for PPTs. CONCLUSIONS The user-independent cuff algometry is reliable for CPM assessment and for supra-pain threshold test stimuli better than the user-dependent technology. SIGNIFICANCE A user-independent CPM technique where the conditioning is controlled by one cuff stimulation, and the test-stimulus is provided by another cuff stimulation. This study shows that cuff algometry is reliable for CPM assessment.

Abstract
BACKGROUND The prognostic significance of serial measurements of serum KL-6 levels in patients with idiopathic pulmonary fibrosis (IPF) is unclear; hence, it was assessed in this study. METHODS Medical records of 66 patients with IPF, who were not treated with pirfenidone prior to enrollment, were retrospectively reviewed for information on clinical progress, forced vital capacity (FVC), survival, and serum KL-6 levels. We assessed initial serum levels of KL-6, serial changes in serum KL-6 levels, yearly decline in FVC (ΔFVC), and the rate of decline (%ΔFVC). RESULTS Patients with increased serum KL-6 levels during follow-up had a significantly steeper decline in ΔFVC than those with no KL-6 increase (-201 vs. -50.7ml/year; p=0.0001). Patients with both initial serum KL-6 ≥1000U/ml and serial increases in serum KL-6 had the steepest decline, while those with both initial serum KL-6 <1000ml and no serial increases in KL-6 had the least decline in ΔFVC and %ΔFVC. Relative to the non-increased KL-6 group, survival in the increased KL-6 group tended to be poorer (p=0.0530). Patients with both initial serum KL-6 values <1000U/ml and no serial increase in KL-6 had more favorable prognoses than those with serial increases in KL-6 or initial serum KL-6 values ≥1000U/ml (p<0.0044). Prognosis was significantly poorer in patients with serial KL-6 changes >51.8U/ml/year than in those with serial KL-6 changes <51.8U/ml/year (p=0.0009). CONCLUSION Thus, serial serum KL-6 measurements can be useful for assessing prognosis in patients with IPF.

Abstract
26,27-F6-1,25(OH)2D3 has a higher potency both in vivo and in vitro systems, and longer duration of action in vivo, instead of almost equal binding to 1,25(OH)2D3 receptor and comparatively short serum half-life. To date, the mechanism of higher action is not known, but using these analogues as a mirror we might be able to elucidate the mechanism of action or the metabolism of the kidney hormone, 1,25(OH)2D3.

Abstract
BACKGROUND The association of diverticula with bowel habits is unclear. We therefore analyzed the association between diverticula and bowel habits in over 1000 Japanese individuals. METHODS Japanese subjects who underwent total colonoscopies at seven centers in Japan from June to September 2013 were analyzed. Bowel habits were evaluated using the Gastrointestinal Symptom Rating Scale, and stool form was assessed using a part of the Bristol Scale and Rome ΙΙΙ criteria. Diverticula were diagnosed by colonoscopy with a transparent soft-short hood. KEY RESULTS The study evaluated 1066 subjects, 648 males and 418 females (ratio, 1.55 : 1), of mean age 63.9 ± 13.0 years. After adjusting for age and sex, the presence of constipation was associated with a significantly reduced likelihood of diverticula (odds ratio [OR] = 0.70, 95% confidence interval [CI] 0.52-0.93). When assessed according to the location of diverticula, the presence of constipation was associated with a significantly decreased likelihood of left-sided (OR = 0.39, 95% CI 0.16-0.93), but not right-sided (OR = 1.10, 95% CI 0.48-2.53), diverticula. Furthermore, stool form was unrelated with the presence or absence of diverticula. CONCLUSIONS & INFERENCES The wide-spread hypothesis that constipation was associated with colonic diverticula was not supported. Rather, we found that the absence of diverticula was associated with constipation, suggesting the need to reassess the etiology of colonic diverticula.

Abstract
BACKGROUND Synovial fluid in inflamed joint shows a drop in pH, which activates proton-gated ion channels in nociceptors. No studies have ever tried to develop and characterize acid-induced joint pain. METHODS Rats were injected intra-articularly with pH 4.0 acidic saline twice, 5 days apart. Pain-related behaviour tests including weight-bearing asymmetry, paw withdrawal threshold and knee compression threshold were conducted. To clarify the roles of proton-gated ion channels, rats were injected intra-articularly with selective antagonists for ASIC1a, ASIC3 and TRPV1 on day 5 (before the second injection) or on day 14. Underlying peripheral and central pain mechanisms were evaluated using joint histology, interleukin-1β concentrations in the synovium, single-fibre recording of the knee afferent and expression of phosphorylated cyclic adenosine monophosphate-responsive element-binding protein (p-CREB) in the spinal dorsal horn. RESULTS Repeated injections of acidic saline induced weight-bearing asymmetry, decrease in paw withdrawal threshold and knee compression threshold bilaterally, which lasted until day 28. Early administration of ASIC3 antagonist reduced the bilateral and long-lasting hyperalgesia. Neither articular degeneration nor synovial inflammation was observed. C-fibre of the knee afferent was activated by acidic saline, which was attenuated by pre-injection of ASIC3 antagonist. p-CREB expression was transiently up-regulated bilaterally on day 6, but not on day 14. CONCLUSION We developed and characterized a model of acid-induced long-lasting bilateral joint pain. Peripheral ASIC3 and spinal p-CREB played important roles for the development of hyperalgesia. This animal model gives insights into the mechanisms of joint pain, which is helpful in developing better pain treatments.

Abstract
The Janus kinase inhibitor tofacitinib is currently being investigated as a disease-modifying agent in rheumatoid arthritis (RA). We investigated the in-vivo effects of tofacitinib treatment for 4 weeks on elevated circulating acute-phase serum amyloid (SAA) levels in 14 Japanese patients with RA. SAA levels fell from 110·5 ± 118·5 μg/ml (mean ± standard deviation) at treatment initiation to 15·3 ± 13·3 μg/ml after 4 weeks treatment with tofacitinib. The reduction in SAA levels was greater in patients receiving tofacitinib plus methotrexate compared with those receiving tofacitinib monotherapy. Tofacitinib was also associated with reduced serum interleukin (IL)-6, but had no effect on serum levels of soluble IL-6 receptor. Patients were divided into groups with adequate (normalization) and inadequate SAA responses (without normalization). Serum IL-6 levels were reduced more in the group with adequate SAA response compared with those with inadequate SAA response. These results suggest that tofacitinib down-regulates the proinflammatory cytokine, IL-6, accompanied by reduced serum SAA levels in patients with active RA. The ability to regulate elevated serum IL-6 and SAA levels may explain the anti-inflammatory activity of tofacitinib.

Abstract
Janus kinase (JAK) inhibitors have been developed as anti-inflammatory agents and have demonstrated clinical efficacy in rheumatoid arthritis (RA). We investigated if JAK-3-selective inhibition alone could disrupt cytokine signalling in rheumatoid synovial fibroblasts. In-vitro studies were performed using synovial fibroblasts isolated from patients with RA. Levels of activated JAK and signal transducer and activator of transcription (STAT) proteins were detected by immunoblot analysis. Target-gene expression levels were measured by reverse transcription-polymerase chain reaction (RT-PCR) or real-time PCR. The JAK inhibitors CP-690,550 and INCB028050 both suppressed activation of JAK-1/-2/-3 and downstream STAT-1/-3/-5, as well as the expression levels of target proinflammatory genes (MCP-I, SAA1/2) in oncostatin-M (OSM)-stimulated rheumatoid synovial fibroblasts. In contrast, the JAK-3-selective inhibitor, PF-956980, suppressed STAT-1/-5 activation but did not affect STAT-3 activation in OSM-stimulated rheumatoid synovial fibroblasts. In addition, PF-956980 significantly suppressed MCP-1 gene expression, but did not block SAA1/2 gene expression in OSM-stimulated rheumatoid synovial fibroblasts. These data suggest that JAK-3-selective inhibition alone is insufficient to control STAT-3-dependent signalling in rheumatoid synovial fibroblasts, and inhibition of JAKs, including JAK-1/-2, is needed to control the proinflammatory cascade in RA.

Abstract
BACKGROUND To assess the impact of childhood abuse history, domestic violence experiences and mental health symptoms on the parenting behaviour of mothers in Japan who have separated from violent husbands or partners. METHODS A self-administered questionnaire survey was conducted on a sample of mothers (n = 304) and their children (n = 498) residing in 83 mother-child homes in Japan. The survey assessed the mothers' childhood abuse history (physical, psychological and sexual abuse and neglect history), domestic violence experiences, current mental health symptoms (dissociative, depressive and traumatic symptoms) and parenting behaviours after moving into the homes to separate from a violent husband or partner. RESULTS The mothers' childhood abuse history and experience of domestic violence were not associated with their not playing with their children. In contrast, the mothers' dissociative and depressive symptoms were significantly associated with not playing with their children. Although there was no association between the mothers' total childhood abuse history and not praising their children, their childhood physical abuse history was significantly associated with their not praising their children. The dissociative and depressive symptoms were also associated with no praise. Interestingly, the experience of domestic violence showed an inverse association with no praise. CONCLUSIONS Mental health symptoms, more specifically dissociative and depressive symptoms, are associated with a decrease in parenting quality. Mothers who were physically abused as children are less likely to praise their own children, independent of maternal mental health symptoms. In contrast, mothers who experienced domestic violence but subsequently separated from their violent husbands or partners are more likely to praise their children. The treatment of mental health symptoms, particularly dissociative and depressive symptoms, therapy for childhood abuse history and separation from violent husbands or partners might be effective ways to enhance the quality of parenting in Japan.

Abstract
Heterochromatin protein 1s (HP1s) are nonhistone chromosomal proteins that play a direct role in the formation and maintenance of heterochromatin structure. Similarly to Caenorhabditis elegans, silkworms possess holocentric chromosomes, in which diffused kinetochores extend along the length of each chromosome. We have isolated two silkworm HP1 homologues, BmHP1a and BmHP1b. Cytological analysis showed a unique localization of BmHP1s during cell division, in which these proteins first appear to dissociate from the chromosomes, but then return to enclose the chromosomes during metaphase. BmHP1s formed homo- and hetero-dimers and interacted with BmSu(var)3-9, which is a methyltransferase for histone H3 lysine 9 (H3K9). We further showed, using a silkworm cell-based reporter system, that BmHP1b had higher transcriptional repression activity than BmHP1a, whereas BmHP1a interacted more strongly with BmSu(var)3-9 than did BmHP1b. These results suggest that silkworm HP1a and HP1b may play different roles in heterochromatin formation in holocentric silkworm chromosomes.

Abstract
Pyoderma gangrenosum is a rare ulcerative disorder of the skin of unknown etiology. We present a case of pyoderma gangrenosum that occurred following total knee arthroplasty, which was initially misdiagnosed as severe wound infection. Repeated debridement procedures resulted in a large soft tissue defect around the anterior knee joint. The patient was treated successfully with a latissimus dorsi musculocutaneous flap under immunosuppressive therapy. Pyoderma gangrenosum is often misdiagnosed as an infected wound, but the treatment for theses differential diagnoses is completely different. When a lesion is refractory to thorough treatment for infection, a diagnosis of pyoderma gangrenosum should be considered.

Abstract
OBJECTIVE The aim of this study was to clarify the characteristic imaging features that can be used to differentiate ameloblastomas from keratocystic odontogenic tumours and to examine the significant imaging features contributing to a correct diagnosis. METHODS 60 observers (39 specialists in oral and maxillofacial radiology and 21 non-specialists) examined CT and/or panoramic images of 10 ameloblastomas and 10 keratocystic odontogenic tumours shown on a webpage and made diagnoses. Their correct answer ratios were then calculated. The imaging features of the tumours were evaluated and expressed as binary numbers or quantitative values. The imaging features that contributed to a correct diagnosis were elucidated using logistic regression analysis. RESULTS The mean correct answer ratio was 61.3% ± 17.2% for the diagnosis of ameloblastomas and keratocystic odontogenic tumours. CT images produced higher correct answer ratios for diagnosis of keratocystic odontogenic tumours by specialists. The significantly different imaging features between ameloblastomas and keratocystic odontogenic tumours were the degree of bone expansion and the presence of high-density areas. The significant imaging features contributing to a correct imaging diagnosis were the number of locules, the presence of high-density areas and the inclusion of impacted teeth. CONCLUSION The presence of high-density areas is the most useful feature in the differential diagnosis of ameloblastomas and keratocystic odontogenic tumours based on comparison of the imaging features of both tumours and examination of the diagnostic contributions of these features.

Abstract
Micropapillary carcinoma is known to be associated with a poor prognosis and high propensity for lymphovascular invasion and lymph node metastasis. Case reports on colorectal micropapillary carcinoma are relatively rare. We report here a 26-year-old woman who had sigmoid colon cancer with a micropapillary component. We made the diagnosis of pulmonary lymphangitic carcinomatosis but could not identify the primary lesion. We gave her chemotherapy as an occult primary cancer. But her respiratory condition did not improve and she died of respiratory failure. Autopsy was performed after her death. The final diagnosis was pulmonary lymphangitic carcinomatosis and multiple lymph node metastases of sigmoid colon cancer with a component of micropapillary carcinoma.

Abstract
A 56-year-old man receiving hemodialysis treatment was hospitalized for examination of a mass in the right middle lobe. Chest computed tomography showed a right hilar mass shadow accompanied by pleural effusion. Non-small cell lung cancer (NSCLC) was diagnosed by cytological examination of the pleural effusion. No epidermal growth factor receptor (EGFR) mutation was found. He was treated with 6 courses of docetaxel as first-line chemotherapy. Docetaxel was administered on the same day as hemodialysis. Adverse events, including hematotoxicity, were managed safely and no delay in administration occurred. This chemotherapy resulted in a partial response. Because docetaxel is metabolized in the liver and does not affect renal function, it can be administered as a standard regimen. This suggests that docetaxel monotherapy is an efficient therapy for non-small cell lung cancer patients receiving hemodialysis.

Abstract
OBJECTIVES The aim was to investigate the effect of changes in horizontal X-ray beam angulation in intraoral radiography on the detection accuracy of furcation defects in the mandibular first molar, and to examine the anatomical relationship between the roots and furcation area as a possible cause of changes in detectability. METHODS Simulated furcation defects with various depths were created in five mandibular first molars. Intraoral radiographs were taken at various horizontal angulations of the projection beams. The diagnostic accuracies were determined based on receiver operating characteristic analysis. The geometric relationship that might influence the accuracy was investigated through use of a compact cone beam CT in 59 first molar areas. RESULTS Although the horizontal angulations showing the highest accuracies were shifted mesially, no differences were found between the angles of -10 degrees and 20 degrees . The relationship between the roots and the furcation area was relevant to the range of angulations showing high detectabilities. CONCLUSIONS The angulations traditionally used for detecting proximal caries are also suitable for detecting furcation defects.

Abstract
BACKGROUND AND OBJECTIVE Although the association of hypertrophic pulmonary osteoarthropathy (HPO) with lung cancer was investigated in the 1960s, the recent incidence of clinically apparent HPO is not known. Data from a large series of patients with lung cancer were analysed, in order to assess the incidence of possible HPO, based on bone scintigraphy, as well as the incidence of clinically confirmed HPO. The clinical features of confirmed HPO were also evaluated. METHODS The medical records of patients admitted with lung cancer between January 1986 and August 2004 were reviewed. Bone scintigraphy showing symmetrical, abnormally high uptake in joints and/or long bones was considered to be suggestive of HPO. Patients who also had finger clubbing and joint pain were considered to have a confirmed diagnosis of HPO. Clinical histories and hormone levels were then investigated in these patients, to identify possible causal factors. RESULTS Among the 1226 lung cancer patients, 55 (4.5%) demonstrated abnormally high uptake on bone scintigraphy, suggesting possible HPO. Ten (0.8%) patients had clubbed fingers and joint pain and were eventually confirmed as having HPO. Serum hormone concentrations were abnormally high in the patients with confirmed HPO. CONCLUSIONS This retrospective study indicated that 4.5% of lung cancer patients showed findings suggestive of HPO, a frequency similar to that reported previously. However, patients with HPO rarely showed the complete triad of signs. Although increased hormone concentrations may have caused the HPO, further investigation is required to confirm this.

Abstract
We report a case of a 28-year-old man with a dry cough and chest pain. Chest X-ray film showed a huge mass in the right lung field. Computed tomography (CT) and magnetic resonance imaging (MRI) showed a huge mass which occupied most of the right thoracic cavity and invaded the superior vena cava, heart atrium and right pulmonary vein. Positron emission tomography (PET) showed metastasis of bone, right adrenal grand and lymph nodes. A tumor specimen was biopsied percutaneously, and the diagnosis was pathologically confirmed as an inflammatory myofibroblastic tumor. Immunohistochemical staining also showed an overexpression of ALK in the tumor. He was treated with a non-steroid anti-inflammation drug and steroid, but they were ineffective. He underwent chemotherapy with bleomicin, etoposide and cisplatin. After two cycles of chemotherapy, the tumor slightly reduced in size, but was eventually refractory to the regimen finally. He also underwent with paclitaxel and carboplatin. At present, if operative extirpation is not possible, there is no way to treat an inflammatory myofibroblastic tumor. In the future, new therapy incorporating ALK inhibitors would be expected to treat those cases of IMT in which local recurrences and distant metastases occur.
