Abstract
PURPOSE/OBJECTIVE(S) The combination of accelerated hyperfractionated thoracic radiotherapy (AHF-TRT) of 45 Gy and concurrent chemotherapy is the standard treatment for limited-stage small-cell lung cancer (LS-SCLC). However, the optimal dose and fractionation remain controversial. We herein report the results of a phase II study investigating the utility of dose escalation to 54 Gy on AHF-RT for LS-SCLC. MATERIALS/METHODS We enrolled patients ≤80 years old with treatment-naïve confirmed LS-SCLC and an Eastern Cooperative Oncology Group (ECOG) performance status of 0-2. The radiation dose was 54 Gy delivered in 36 fractions in 18 treatment days over 3.6 weeks. The chemotherapy regimens were PE (cisplatin and etoposide)- or CE (carboplatin and etoposide)-based. AHF-TRT was given in 2 phases: patients initially received 36 Gy to the gross tumor plus uninvolved mediastinal nodes, followed by a boost to the gross tumor of 18 Gy. All patients were treated with three-dimensional conformal radiation therapy with multiple fields to reduce the elevated dose volume to the surrounding tissues, such as the lungs and esophagus, as much as possible. All patients were evaluated for the overall survival (OS), progression-free survival (PFS), and non-hematological toxicity. RESULTS Between 2013 and 2016, a total of 13 patients were enrolled in the present study. All the patients were assessable for the response and toxicity. The median age was 67 (range, 54-78) years old, and 9 patients were male, while 4 were female. Twelve patients had a ECOG performance status of 0. The numbers of patients with Stage IIA, IIB, IIIA, and IIIB disease were one, one, eight, and three, respectively. The median follow-up for all patients was 79 (range, 13-107) months, and that for surviving patients was 90 (range, 79-107) months. The patterns of failure were locoregional-only recurrence in 0% (0 patients), both locoregional and distant in 15.4% (2 patients), and distant-only in 30.8% (4 patients). Recurrence from the elective nodal irradiation area was seen in 0% (0 patients). The 1-, 3-, 5-, and 7-year OS rates were 100%, 76.9%, 53.9%, and 44.9%, respectively, and the median OS was 83.0 months. The 1-, 3-, 5-, and 7-year PFS rates were 76.9%, 53.9%, 53.9%, and 44.9%, respectively, and the median PFS was 83.0 months. No patient experienced a grade ≥3 non-hematological adverse effect, such as esophagitis or pneumonitis, during treatment or follow-up. Grade 2 pneumonitis was observed in 2 patients (15.4%), Grade 2 esophagitis was observed in 12 patients (92.3%), and Grade 2 esophageal pain was observed in 2 patients (15.4%). CONCLUSION In this study, AHF-TRT of 54 Gy with concurrent PE- or CE-based regimens resulted in a good OS and PFS without increasing severe toxicity. Although this regimen needs to be evaluated in more patients to fully confirm its efficacy, these outcomes suggest that dose escalation to 54 Gy may be a promising radical treatment for LS-SCLC.

Abstract
This study investigated the long-term survival and incidence of secondary fractures after fragility hip fractures. The 5-year survival rate was 62%, and the mortality risk was seen in patients with GNRI < 92. The 5-year incidence of secondary fracture was 22%, which was significantly higher in patients with a BMI < 20. BACKGROUND Malnutrition negatively influences the postoperative survival of patients with fragility hip fractures (FHFs); however, little is known about their association over the long term. OBJECTIVE This study evaluated the ability of the geriatric nutritional risk index (GNRI) as a risk factor for long-term mortality after FHFs. METHODS This study included 623 Japanese patients with FHFs over the age of 60 years. We prospectively collected data on admission and during hospitalization and assessed the patients' conditions after discharge through a questionnaire. We examined the long-term mortality and the incidence of secondary FHFs and assessed the prognostic factors. RESULTS The mean observation period was 4.0 years (range 0-7 years). The average age at the time of admission was 82 years (range 60-101 years). The overall survival after FHFs (1 year, 91%; 5 years, 62%) and the incidence of secondary FHFs were high (1 year, 4%; 5 years, 22%). The multivariate Cox proportional hazard analysis revealed the risk factors for mortality as older age (hazard ratio [HR] 1.04), male sex (HR 1.96), lower GNRI score (HR 0.96), comorbidities (malignancy, HR 2.51; ischemic heart disease, HR 2.24; revised Hasegawa dementia scale ≤ 20, HR 1.64), no use of active vitamin D3 on admission (HR 0.46), and a lower Barthel index (BI) (on admission, HR 1.00; at discharge, HR 0.99). The GNRI scores were divided into four risk categories: major risk (GNRI, < 82), moderate risk (82-91), low risk (92-98), and no risk (> 98). Patients at major and moderate risks of GNRI had a significantly lower overall survival rate (p < 0.001). Lower body mass index (BMI) was also identified as a prognostic factor for secondary FHFs (HR 0.88 [p = 0.004]). CONCLUSIONS We showed that older age, male sex, a lower GNRI score, comorbidities, and a lower BI are risk factors for mortality following FHFs. GNRI is a novel and simple predictor of long-term survival after FHFs.

Abstract
AIM In Cambodia, civil unrest has led to insufficient and inaccessible dental health services. Oral health education and awareness are lacking, thus childhood dental caries is highly prevalent. This study aimed to examine the effects of an oral health education programme for public primary school teachers on the pupils' oral health. METHODS Between 2011 and 2015, an oral health education workshop was presented annually to primary school educators employed at a public school in Siem Reap, Cambodia. Oral screenings of 2,637 pupils (grades 1-6; subdivided between the lower 1-3 and upper 4-6 grades) were undertaken and the prevalence of dental caries, mean number of DFT, and mean percentage of DFT rate were calculated. CONCLUSION Despite the persistently high prevalence of dental caries, the oral health status of the schoolchildren improved every year. Participation in the workshops may have improved the teachers' ability to provide oral healthcare instructions, leading to the reduced dental caries prevalence among pupils.

Abstract
INTRODUCTION There are no clinical prediction models to predict the prognosis of pre-frailty or frailty in patients with heart failure. We aimed to develop prediction models for the prognosis of pre-frailty and frailty in older patients with heart failure using the classification and regression tree (CART) method; we then tested the predictive accuracies of the developed models. METHODS Patients with pre-frailty or frailty at admission were divided into improved and non-improved groups. The CART method was used to establish two models: A, which predicted the presence or absence of pre-frailty improvement during hospitalisation; and B, which predicted the presence or absence of frailty improvement during hospitalisation. RESULTS Patients with heart failure complicated by pre-frailty (n=28) or frailty (n=156) were included. In model A, the accuracy of predicting pre-frailty improvement was high; the best predictor was single-leg standing time at admission, followed by left ventricular ejection fraction at admission. In model B, the accuracy of predicting frailty improvement was moderate; the best predictor was hand grip strength at admission, followed by estimated glomerular filtration rate at admission, haemoglobin level at admission, and change in single-leg standing time during hospitalisation. The areas under the receiver operating characteristic curves of the CART models were 0.96 and 0.84 in models A and B, respectively. CONCLUSION Although conditions at admission may predict the improvement of pre-frailty and frailty during hospitalisation, cardiac rehabilitation that improves single-leg standing time may help to improve frailty, particularly when conditions at admission are poor.

Abstract
BACKGROUND Cancer of unknown primary (CUP) has a poor prognosis. Given the recent approval of immune checkpoint inhibitors for several cancer types, we carried out a multicenter phase II study to assess the efficacy of nivolumab for patients with CUP. PATIENTS AND METHODS Patients with CUP who were previously treated with at least one line of systemic chemotherapy constituted the principal study population. Previously untreated patients with CUP were also enrolled for exploratory analysis. Nivolumab (240 mg/body) was administered every 2 weeks for up to 52 cycles. The primary endpoint was objective response rate in previously treated patients as determined by blinded independent central review according to RECIST version 1.1. RESULTS Fifty-six patients with CUP were enrolled in the trial. For the 45 previously treated patients, objective response rate was 22.2% [95% confidence interval (CI), 11.2% to 37.1%], with a median progression-free survival and overall survival of 4.0 months (95% CI, 1.9-5.8 months) and 15.9 months (95% CI, 8.4-21.5 months), respectively. Similar clinical benefits were also observed in the 11 previously untreated patients. Better clinical efficacy of nivolumab was apparent for tumors with a higher programmed death-ligand 1 expression level, for those with a higher tumor mutation burden, and for microsatellite instability-high tumors. In contrast, no differences in efficacy were apparent between tumor subgroups based on estimated tissue of origin. Adverse events were consistent with the known safety profile of nivolumab. No treatment-related death was observed. CONCLUSIONS Our results demonstrate a clinical benefit of nivolumab for patients with CUP, suggesting that nivolumab is a potential additional therapeutic option for CUP.

Abstract
Optical grade Dy2O3 ceramics was successfully produced by adding a small amount of ZrO2 as a sintering aid and hot isostatic pressing treatment at 1500∘C after pre-sintering at 1550∘C. No residual pores, grain boundary phases, or second phases were detected inside the transparent ceramics. Since birefringence was not observed under the polarizer, the produced Dy2O3 ceramics is an optically isotropic body. There was almost no beam distortion during the laser irradiation test, and the optical loss was extremely small (<0.1%/cm). The Verdet constant was 422radT-1m-1 at a wavelength of 633 nm, and the extinction ratio was 34 dB.

Abstract
Background Amrubicin is approved for treating non-small-cell lung cancer (NSCLC) and small-cell lung cancer. However, no direct comparisons between amrubicin and docetaxel, a standard treatment for NSCLC, have been reported. Patients and methods We conducted a randomized phase III trial of Japanese NSCLC patients after one or two chemotherapy regimens. Patients were randomized to amrubicin (35 mg/m2 on days 1-3 every 3 weeks) or docetaxel (60 mg/m2 on day 1 every 3 weeks). Outcomes included progression-free survival, overall survival, tumor responses, and safety. Results Between October 2010 and June 2012, 202 patients were enrolled across 32 institutions. Median progression-free survival (3.6 versus 3.0 months; P = 0.54) and overall survival (14.6 versus 13.5 months; P = 0.86) were comparable in the amrubicin and docetaxel groups, respectively. The overall response rate was 14.4% (14/97) and 19.6% (19/97) in the amrubicin and docetaxel groups, respectively (P = 0.45). The disease control rate was 55.7% in both groups. Adverse events occurred in all patients, and included grade ≥3 neutropenia occurred in 82.7% and 78.8% of patients in the amrubicin and docetaxel groups, respectively, grade ≥3 leukopenia occurred in 63.3% and 70.7%, and grade ≥3 febrile neutropenia occurred in 13.3% and 18.2% of patients in the amrubicin and docetaxel groups, respectively. Of eight cardiac-related events in the amrubicin group, three were considered related to amrubicin and resolved without treatment discontinuation. Conclusions This was the first phase III study to compare amrubicin and docetaxel in patients with pretreated NSCLC. Amrubicin did not significantly improve the primary endpoint of PFS compared with docetaxel. Clinical trial registration NCT01207011 (ClinicalTrials.gov).

Abstract
BACKGROUND The fatigue strength of three peripheral suture techniques for flexor tendon repair was compared by cyclic loading of the repairs in the porcine flexor digitorum tendon. METHODS Thirty-six tendons were sutured using only peripheral sutures with 6-0 Nylon. An initial cyclic load of 10 N for 500 cycles was applied and increased by 10 N for an additional 500 cycles at each new load until rupture. RESULTS The fatigue strength of the symmetric running peripheral suture was 85.0% and 144.8% greater than that of the two kinds of the asymmetric running peripheral sutures. CONCLUSIONS Symmetric running sutures can enhance the suture strength and appears to be a useful technique for increasing the strength of the peripheral suture.

Abstract
We herein report an unusual case of Brodie's abscess of the radius in a child. A 13-year-old boy presented with pain on his right distal forearm. A plain radiograph showed an 8 cm translucent lesion in the distal radius. MRI showed a penumbra sign on the T1-weighted image, hyperintensity on T2-weighted images, and ring enhancement on the contrast-enhanced T1 image. 18F-FDG PET/CT images showed an uptake at the margin of the radius. Curettage and iliac cancellous bone grafting were undertaken for Brodie's abscess. Bacteriological examinations were found to be negative, however, the pathologic diagnosis showed chronic osteomyelitis. Eight months after surgery, the patient was asymptomatic and there was no sign of recurrence of infection. For Brodie's abscess in a child, thorough debridement is mandatory in addition to cancellous bone grafting. Brodie's abscess should be considered in the differential diagnosis of a patient who presents with forearm pain and exhibit the radiolucent osteolytic lesion on simple radiography.

Abstract
UNLABELLED We evaluated the influence of baseline age, bone mineral density (BMD), and serum levels of vitamin D on the response to risedronate treatment. Risedronate consistently increased BMD, but our results suggest vitamin D supplementation may be necessary to achieve optimal treatment effect. Furthermore, early intervention may help prevent bone fractures. INTRODUCTION We aimed to investigate the influence of baseline age, BMD, and vitamin D insufficiency on the response to risedronate treatment. METHODS Data regarding 1447 patients was obtained from the registries of three phase III clinical trials of risedronate. The response to treatment was expressed in terms of BMD increase and occurrence of new vertebral fractures. The patients were stratified by baseline values for age (<65, 65-72, and ≥72 years), lumbar spine BMD T-score (osteoporotic, <-2.5; and non-osteoporotic, ≥- 2.5), and serum levels of 25-hydroxyvitamin D (deficient, <21 ng/mL; and non-deficient, ≥21 ng/mL). RESULTS Risedronate consistently increased lumbar spine BMD in all the groups, with similar percentage and absolute increments in all the age tertiles. The percentage, but not absolute, increment in BMD was significantly higher (p = 0.0003) in the osteoporotic than that in the non-osteoporotic patients (baseline). Of the 1330 patients whose baseline serum levels of 25-hydroxyvitamin D were available, 44.7% had vitamin D deficiency (<20 ng/mL), while 89.2% had insufficiency (<30 ng/mL). The percentage and absolute increments in BMD were lower (p < 0.05 and p < 0.01, respectively) in the vitamin D-deficient than those in the non-deficient patients. New vertebral fractures occurred in 1.5 and 0.8% of the osteoporotic and non-osteoporotic patients, respectively (end of the treatment). CONCLUSIONS Therapeutic response in elderly patients is consistent, but early initiation of risedronate treatment may help prevent fractures. Risedronate-induced increase in BMD is lower in patients with vitamin D deficiency, suggesting that vitamin D supplementation is important to achieve optimal treatment response.

Abstract
Under cyclic loading, we recorded the fatigue strength of a six-strand tendon repair with different symmetry in the lengths of suture purchase in two stumps of 120 dental rolls and in 30 porcine tendons. First, the strengths of the repairs with 1, 2, 3, 4 and 5 mm asymmetry were screened using the dental rolls. The asymmetric core suture repairs were then made with a Kessler repair of equal suture purchase (10 mm) in two tendon stumps, and shifting two other Kessler repairs by 1, 3 or 5 mm, respectively, along the longitudinal axis of the tendon in relation to the first (symmetric) Kessler repair. The core repairs with 3 mm or more asymmetry in suture purchases in two tendon ends showed significantly greater fatigue strength and significantly smaller gaps compared with 1 mm asymmetry in core suture repair. Our results support that asymmetric placement of core sutures in two tendon ends favour resisting gapping at the repair site and 3 mm or more asymmetry is needed to produce such beneficial effects.

Abstract
We planned the INNOVATION study to determine whether telmisartan, an angiotensin-2-receptor blocker, delays the progression of renal disease from incipient nephropathy to overt nephropathy in hypertensive or normotensive Japanese patients with type 2 diabetes mellitus. The INNOVATION study is a randomized, double-blind, placebo-controlled trial. Eligible patients must have incipient nephropathy (defined as a urinary albumin to creatinine ratio of 100-300 mg/g creatinine) and a serum creatinine concentration of < 1.5 mg/dl for men and < 1.3 mg/dl for women. Patients who need treatment with angiotensin II receptor blockers or angiotensin-converting enzyme inhibitors are excluded. Eligible patients are randomly assigned to three groups: telmisartan titrated to 40 mg; telmisartan titrated to 80 mg; or placebo. The primary endpoint is the time from baseline visit to first detection of overt nephropathy (defined by a urinary albumin to creatinine ratio that is > 300 mg/g creatinine and 30% higher than the baseline on at least two consecutive visits). A total of 1855 patients have been enrolled from 160 study centres. In 527 randomized patients (28.4% of the enrolled patients), mean (SD) urinary albumin to creatinine ratio and serum creatinine concentration at baseline were 173.3 (47.2) mg/g creatinine and 0.78 (0.19) mg/dl. Sixty-eight per cent of the patients had hypertension at baseline. Mean (SD) systolic and diastolic blood pressures at baseline were 137.1 (14.6) and 77.5 (10.3) mmHg. The INNOVATION study will determine whether telmisartan, an angiotensin II receptor blocker, provides clinical benefits in hypertensive or normotensive patients with diabetes mellitus and diabetic nephropathy.

Abstract
After several years of treatment for type 2 diabetes mellitus, a 69-year-old Japanese man developed an acute painful neuropathy, characterized by bilateral causalgia and dysaesthesia in his cheeks and around his eyes, typically 30 min to 3h after meals. As his glycaemic control deteriorated, his haemoglobin (Hb) A1c level gradually increased from 7-8% to 10.3% and his symptoms became more severe. The pain radiated out along the distribution of the ophthalmic and maxillary divisions of the trigeminal nerve. The patient was treated with insulin therapy and his HbA1c level decreased from 10.3% to 6.8% within 7 months. Five months after initiating insulin therapy, his symptoms showed a dramatic improvement. This was a very unusual case of bilateral acute painful neuropathy that involved the ophthalmic and maxillary divisions of the trigeminal nerve, and in which aggravation of the symptoms clearly related to poor glycaemic control.

Abstract
OBJECTIVES Because there have been no standard methods to determine pre-operatively the thickness of resection of the proximal tibia in unicompartmental knee arthroplasty (UKA), information about the relationship between the change of limb alignment and the joint line elevation would be useful for pre-operative planning. The purpose of this study was to clarify the correlation between the change of limb alignment and the change of joint line height at the medial compartment after UKA. METHODS A consecutive series of 42 medial UKAs was reviewed retrospectively. These patients were assessed radiographically both pre- and post-operatively with standing anteroposterior radiographs. The thickness of bone resection at the proximal tibia and the distal femur was measured radiographically. The relationship between the change of femorotibial angle (δFTA) and the change of joint line height, was analysed. RESULTS The mean pre- and post-operative FTA was 180.5° (172.2° to 184.8°) and 175.0° (168.5° to 178.9°), respectively. The mean δFTA was 5.5° (2.3° to 10.1°). The joint line elevation of the tibia (JLET) was 4.4 mm (2.1 to 7.8). The δFTA was correlated with the JLET (correlation coefficient 0.494, p = 0.0009). CONCLUSIONS This study indicated that there is a significant correlation between the change of limb alignment and joint line elevation. This observation suggests that it is possible to know the requirement of elevation of the joint line to obtain the desired correction of limb alignment, and to predict the requirement of bone resection of the proximal tibia pre-operatively.

Abstract
Insulin degludec (IDeg) is a novel basal insulin analogue with an ultralong duration of action that provides flat and stable reductions in blood glucose. The BEGIN ONCE ASIA trial was a phase 3 pan-Asian study examining the efficacy and safety of IDeg once daily (OD) versus insulin glargine (IGlar) OD in insulin-naive patients with type 2 diabetes (T2D). In this multinational, 26-week, open-label, treat-to-target trial, participants were randomised (2:1) to IDeg OD or IGlar OD, administered with one or more antidiabetic drugs (OAD) per os. Here we report the results from a post hoc analysis of Japanese patients enrolled in the trial [n = 133; 63.2 % male; mean age 61.0 years; mean body mass index 24.1 kg/m2; mean glycosylated haemoglobin (HbA1c) 8.5 %]. After 26 weeks, mean HbA1c levels were similar between the two groups [estimated mean treatment difference 0.11 %; 95 % confidence interval (CI) -0.09, 0.31]. Confirmed hypoglycaemia was reported in 53.4 and 61.4 % of patients in the IDeg OD and IGlar OD groups [rate ratio (IDeg/IGlar) 0.87; 95 % CI 0.51, 1.48]. Confirmed nocturnal hypoglycaemia was reported in 17.0 and 22.7 % of patients in the IDeg OD and IGlar OD groups, respectively [rate ratio (IDeg/IGlar) 0.50; 95 % CI 0.19, 1.32]. Adverse event rates were similar between treatment groups. Initiating insulin treatment with IDeg OD in Japanese patients with T2D, inadequately maintained on OADs and requiring treatment intensification, provided effective glycaemic control with low rates of confirmed and nocturnal confirmed hypoglycaemia.

Abstract
BACKGROUND Thymic carcinoma (TC) is an exceptionally rare tumor, which has a very poor prognosis differing from thymoma. Till date, there has been no report of any results of clinical trials focusing on TC. The role of non-anthracycline-based chemotherapy has not been elucidated since the previous studies included a relatively small number of TC patients. This single-arm study evaluated carboplatin and paclitaxel (CbP) in chemotherapy-naive patients with advanced TC. PATIENTS AND METHODS The study treatment consisted of carboplatin (area under the curve 6) and paclitaxel (200 mg/m(2)) every 3 weeks for a maximum of six cycles. The primary end point was objective response rate (ORR) by independent review. The secondary end points included overall survival (OS), progression-free survival (PFS), and safety. Based on the SWOG 2-stage design, the planned sample size of 40 patients was determined to reject the ORR of 20% under the expectation of 40% with a power of 0.85 and a type I error of 0.05. RESULTS Forty patients from 21 centers were enrolled for this study from May 2008 to November 2010. Of the 39 patients evaluable for analysis, 36 were pathologically diagnosed by independent review, and 97% patients were eventually TC. There was 1/13 complete/partial responses with an ORR of 36% (95% confidence interval 21%-53%; P = 0.031). The median PFS was 7.5 (6.2-12.3) months, while OS did not reach the median value. Major adverse event was grade 3-4 neutropenia in 34 patients (87%). There was no treatment-related death. CONCLUSIONS In this largest trial with TC, CbP showed promising efficacy in advanced TC when compared with anthracycline-based chemotherapy, which is the current standard treatment of thymic neoplasm. Our results established that CbP, one of the standard treatments for non-small-cell lung cancer, might be an option as a chemotherapy regimen for TC.

Abstract
Neutron activation cross sections for Bi and Co at 386 MeV were measured by activation method. A quasi-monoenergetic neutron beam was produced using the (7)Li(p,n) reaction. The energy spectrum of these neutrons has a high-energy peak (386 MeV) and a low-energy tail. Two neutron beams, 0° and 25° from the proton beam axis, were used for sample irradiation, enabling a correction for the contribution of the low-energy neutrons. The neutron-induced activation cross sections were estimated by subtracting the reaction rates of irradiated samples for 25° irradiation from those of 0° irradiation. The measured cross sections were compared with the findings of other studies, evaluated in relation to nuclear data files and the calculated data by Particle and Heavy Ion Transport code System code.

Abstract
OBJECTIVES The purpose of this study was to investigate the association of the shape of the mandibular cortex on panoramic radiographs with the risk of an osteoporosis diagnosis without prevalent fractures and with the risk of osteoporotic fractures in Japanese men and women. SUBJECTS AND METHODS One thousand and twenty-one subjects aged 40-89 years, who visited our university hospital and underwent panoramic radiography between 2007 and 2013, participated in this study. Eighty-eight patients received a diagnosis of osteoporosis without prevalent fractures, and 55 were diagnosed with osteoporotic fractures. Blinded to the groupings, we classified the shape of the mandibular cortex on panoramic radiographs as normal, moderately eroded or severely eroded. RESULTS After adjustment for confounding factors, the odds ratios for an osteoporosis diagnosis associated with moderately eroded and severely eroded mandibular cortices were 1.4 (95% CI, 0.8-2.6) and 2.6 (95% CI, 1.4-5.0), respectively. The odds ratios for an osteoporotic fracture associated with moderately eroded and severely eroded cortices were 0.8 (95% CI, 0.4-1.7) and 1.1 (95% CI, 0.5-2.5), respectively. CONCLUSIONS Subjects in Japan with eroded mandibular cortices tended to be at increased risk of osteoporosis diagnoses but not of fractures.

Abstract
Abstract Ankylosing spondylitis (AS) is occasionally accompanied by erosive changes in the vertebral endplate at one or more restricted levels (Andersson lesions). The radiographic findings of this lesion are similar to those of bacterial discitis, and a differential diagnosis between them is often difficult. These diseases must be diagnosed correctly because they require different treatments. In order to evaluate the prevalence of Andersson lesions in the Japanese population, we examined 31 cases of AS which were treated in our department, and Andersson lesions were found in three (9.7%) of them. All these three cases developed Andersson lesions in the earlier phase of the AS, and differentiating the lesions from bacterial discitis was difficult. The details of these three cases are reviewed, and the importance of differentiating between Andersson lesions and bacterial discitis is discussed. Plain radiographs showed no clear difference between these conditions, but magnetic resonance imaging (MRI) was found to be more efficient.

Abstract
OBJECTIVE Aging is a major risk factor for osteoarthritis (OA). Forkhead-box class O (FoxO) transcription factors regulate mechanisms of cellular aging, including protein quality control, autophagy and defenses against oxidative stress. The objective of this study was to analyze FoxO transcription factors in normal, aging and OA cartilage. DESIGN Knee joints from humans ages 23-90 and from mice at the age of 4-24 months and following surgically induced OA were analyzed for expression of FoxO proteins. Regulation of FoxO protein expression and activation was analyzed in cultured chondrocytes. RESULTS Human cartilage expressed FOXO1 and FOXO3 but not FOXO4 proteins. FOXO1 and FOXO3 were more strongly expressed the superficial and mid zone as compared to the deep zone and were mainly localized in nuclei. During human joint aging, expression of FOXO1 and FOXO3 was markedly reduced in the superficial zone of cartilage regions exposed to maximal weight bearing. In OA cartilage, chondrocyte clusters showed strong FOXO phosphorylation and cytoplasmic localization. Similar patterns of FOXO expression in normal joints and changes in aging and OA were observed in mouse models. In cultured chondrocytes, IL-1β and TNF-α suppressed FOXO1, while TGF-β and PDGF increased FOXO1 and FOXO3 expression. FOXO1 and FOXO3 phosphorylation was increased by IL-1β, PDGF, bFGF, IGF-1, and the oxidant t-BHP. CONCLUSIONS Normal articular cartilage has a tissue specific signature of FoxO expression and activation and this is profoundly altered in aging and OA in humans and mice. Changes in FoxO expression and activation may be involved in cartilage aging and OA.

Abstract
In order to evaluate diclofenac-Na (DC-Na) micro-enema, DC-Na gel preparations were administered to rats and man. When DC-Na gel preparations were rectally administered at various pH (pH 5- 8) to rats, their bioavailability increased at higher pH. The bioavailability of DC-Na gel preparations (pH 8.0) in rats was significantly higher than that with conventional suppository bases, Witepsol H-15 and polyethylene glycol 1000 (PEG 1000). In man, the DC-Na gel preparation showed higher Cmax and higher bioavailability than commercial suppository made with an oily base. DC-Na gel preparations containing 10% v/v oleic acid showed a prolonged action. The irritative effect of DC-Na gel preparation on rectal mucosa in rats was weaker than that of PEG 1000, but similar to that of Witepsol H-15. Therefore, the present results suggest that gel preparation is a favorable form for rectal administration of diclofenac-Na.
