| 抄録 | We retrospectively reviewed 29 hips in which intertrochanteric osteotomies were performed for severe slipped capital femoral epiphyses. Mean age at surgery: 12.6 years. Mean follow-up period: 6 years. At the final follow-up evaluation, one patient had coxalgia, and six hips showed a limited range of motion. A pistol-grip deformity was observed in 13 hips, osteoarthritis in two hips, and a bump existed in 19 hips on the latest radiographs. Gradual remodeling of the bumps was observed post-operatively in 22 hips. The mean α and β angles and offset α and β improved over time. The remodeling proceeded rapidly for 1 year post-surgery. We compared hips classified as β angles of ≥ 63° to < 63° at the final follow-up evaluation, the mean β angle 1 year post-surgery, and the mean ratio of improvement of the β angle per year from 1 year post-surgery to the final follow up, which differed significantly. Nearly all of the patients who underwent intertrochanteric osteotomies had residual morphologic abnormalities, but few had clinical symptoms. The β angle 1 year post-surgery and the ratio of remodeling of the bump from 1 year post-surgery to the final follow-up can be regarded as a potential predictor of morphologic results after intertrochanteric osteotomy. |

| 抄録 | We investigated the link between proteinuria and psychological distress among patients with type 2 diabetes mellitus (T2DM). A total of 130 patients with T2DM aged 69.1±10.3 years were enrolled in this cross-sectional study. Urine and blood parameters, age, height, body weight, and medications were analyzed, and each patient’s psychological distress was measured using the six-item Kessler Psychological Distress Scale (K6). We compared the K6 scores between the patients with and without proteinuria. Forty-two patients (32.3%) had proteinuria (≥±) and the level of HbA1c was 7.5±1.3%. The K6 scores of the patients with proteinuria were significantly higher than those of the patients without proteinuria even after adjusting for age and sex. The clinical impact of proteinuria rather than age, sex and HbA1c was demonstrated by a multiple regression analysis. Proteinuria was closely associated with higher psychological distress. Preventing and improving proteinuria may reduce psychological distress in patients with T2DM. |

| 抄録 | Two-stage revision total hip arthroplasty (THA) is the most commonly used treatment approach for deep prosthetic infection. However, in this approach the interval between the first and second stage tends to be prolonged. We devised a strategic protocol for improving the infection eradication rate and shortening the interval between the stages in two-stage revision THA. This study analyzed a series of 14 patients (14 hips) from 2008 to 2012, who were treated using an antibiotic-loaded acrylic cement (ALAC) spacer at the first stage and re-implantation at the second stage. The ALAC included vancomycin and amikacin for most of the cases. Patients with MRSA infection were additionally administered intravenous vancomycin in combination with either oral rifampicin or trimethoprim-sulfamethoxazole. The average interval between the stages was 54.2 days overall, and 58.7 days for cases with MRSA infection. Our infection eradication rate was 100%, with no reported recurrence of infection. The presence of MRSA tended to be associated with a longer interval between the two stages. Our protocol for two-stage revision THA was associated with a high eradication rate of infection and a shortened interval between the stages. |

| 抄録 | The effect of skeletal muscle mass (SMM) on the outcomes of sorafenib treatment for hepatocellular carcinoma (HCC) has not been established. We measured the SMM in HCC patients treated with sorafenib, evaluated the patients’ survival, and evaluated the association between skeletal muscle depletion and sorafenib treatment. Of the 97 HCC patients treated with sorafenib at our institution in the period from July 2009 to February 2015, our study included 69 patients (51 males, 18 females) who had received sorafenib for ≥ 8 weeks and whose follow-up data were available. SMM was calculated from computed tomography images at the mid-L3 level (cm2) and normalized to height (m2) to yield the L3 skeletal muscle index (L3-SMI, cm2/m2). The median L3-SMI value was higher in the males (43 cm2/m2) compared to the females (36 cm2/m2). In the males only, the multivariate Cox regression identified an L3-SMI <43 cm2/m2 as independently associated with higher mortality compared to an L3-SMI ≥43 cm2/m2 (hazard ratio 2.315, 95% confidence interval: 1.125-4.765, p=0.023). Skeletal muscle depletion is a factor predicting poor prognosis for male patients with advanced HCC treated with sorafenib. |

| 抄録 | We developed a surface matching-type computed tomography (CT)-based navigation system for total hip arthroplasty (the N-navi; TEIJIN NAKASHIMA MEDICAL, Okayama, Japan). In the registration step, surface matching was performed with digitizing points on the pelvic bone surface after coarse paired matching. In the present study, we made model bones from the CT data of patients whose acetabular shapes had various deformities. We measured the distances and angles after surface matching from the fiducial points and evaluated the ability to correct surface-matching registration on each pelvic form, using several areas and numbers of points. When the surface-matching points were taken on the superior area of the acetabulum, the correction was easy for the external direction, but it was difficult to correct for the anterior and proximal directions. The correction was difficult for external and proximal directions on the posterior area. Each area of surface-matching points has particular directions that are easily corrected and other directions that are difficult to correct. The shape of the pelvis also affected the correction ability. Our present findings suggest that checking the position after coarse paired matching and choosing the surface-matching area and points that are optimal to correct will improve the accuracy of total hip arthroplasty and reduce surgical times. |

| 抄録 | Achieving sufficient support of the anterior cortex of the femoral neck is a fundamental goal of the reduction of trochanteric fractures. However, anterior-cortex support is often lost after the fracture reduction. Our aim was to analyze factors contributing to the postoperative displacement of an acceptably reduced trochanteric fracture. The cases of 40 patients with a post-reduction Ikuta subtype N fracture alignment were reviewed. All fractures were fixed with 135° free-sliding plates. On postoperative day 14, patients were classified into two groups: those with retention of the Ikuta subtype N alignment, and those with progression to Ikuta subtype P alignment. The clinical and radiological factors were evaluated between the groups. In addition, to define one of the factors, i.e., the postoperative rotational displacement between the proximal and distal fragments, the relationship between radiographic findings and computed tomography image measurements was assessed in 15 of the 40 patients. Angulation at the fracture site on lateral view radiographs was defined as postoperative rotational displacement, and unstable trochanteric fractures and postoperative rotational displacement were identified as significant risk factors for the postoperative displacement. Therefore, cautious and careful follow-up is warranted for patients with unstable trochanteric fractures or fractures having rotational displacement. |

| 抄録 | To date, many animal studies have indicated the neuroprotective effects of mesenchymal stem cell (MSC) transplantation in ischemic stroke. Several clinical studies have also revealed the safety, feasibility, and neuroprotective effects in ischemic stroke patients. In this review, we present the main approaches of MSC transplantation in ischemic stroke, the mechanisms of MSC therapy, and the current clinical studies on MSC transplantation in ischemic stroke patients. We also explore the safety of MSC transplantation and conclude that MSC therapy will play an important role in the future treatment of ischemic stroke. The optimal timing, approach, and cell dose in the transplantation are important issues for successful clinical application. |

| 抄録 | Primary sternal chondrosarcoma is a rare malignant tumor that is refractory to chemotherapy and radiation. Effective therapy is radical resection of the tumor. We present two patients with primary sternal chondrosarcoma who underwent a radical resection of the lower half of the sternum and bilateral ribs, followed by reconstruction with 2 sheets of polypropylene mesh layered orthogonally. The patients have maintained almost the same pulmonary function as preoperative values, with stability of the chest wall. Although there are various ways to reconstruct the anterior chest wall, reconstruction with polypropylene mesh layered orthogonally is an easy-to-use and sufficient method. |

| 抄録 | We diagnosed a female infant with Langerhans cell histiocytosis (LCH) who was refractory to conventional chemotherapy. She showed refractory inflammation that was complicated with hemophagocytic lymphohistiocytosis (HLH) during LCH chemotherapy; therefore, we changed the protocol to HLH2004 (dexamethasone, cyclosporine A and VP16). However, there were no signs of hematological recovery. We therefore performed cord blood transplantation with reduced-intensity conditioning, and she achieved complete remission for over 2 years. As salvage therapy for refractory LCH, hematopoietic stem cell transplantation may be a good therapeutic choice, especially when LCH is complicated with HLH. |

| 抄録 | Most gastric bezoars can be treated with endoscopic fragmentation combined with or without cola dissolution, whereas laparotomy or laparoscopic surgery is generally inevitable for small intestinal bezoars because they cause small bowel obstruction. Therefore, early diagnosis and management of gastric bezoars are necessary to prevent bezoar-induced ileus. To investigate the incidence of overlooked gastric bezoars during the initial esophagogastroduodenoscopy, we retrospectively reviewed the cases of 27 patients diagnosed with gastrointestinal bezoars. The bezoars were diagnosed using esophagogastroduodenoscopy (n=25), abdominal ultrasonography (n=1), and barium follow-through examination (n=1). Bezoars were overlooked in 9/25 patients (36.0%) during the initial endoscopy examination because the bezoars were covered with debris in the stomach. Of the 9 patients, 8 had concomitant gastric ulcers, and the other patient had gastric lymphoma. Although a computed tomography (CT) scan was performed before the second-look endoscopy in 8 of the 9 patients, the bezoars were mistaken as food debris on CT findings and were overlooked in these patients. In conclusion, gastric bezoars may not be discovered during the initial esophagogastroduodenoscopy and CT scan. In cases with debris in the stomach, second-look endoscopy is essential to detect bezoars. |

| 抄録 | Ductal carcinoma in situ (DCIS) of the breast has no potential to metastasize, but over 20% of cases preoperatively diagnosed as DCIS are upstaged on final pathology. The rates of upstaging and the predictors for invasion on final pathology were evaluated. For 240 primary breast cancers, radiological findings on mammography, ultrasonography, and magnetic resonance imaging were investigated along with pathological and clinical information. Univariate and multivariate analyses were performed to identify predictors of potential invasion. Of the 240 breast cancers, 68 (28.3%) showed invasion on final pathology, and 5 (2.5%) had sentinel node metastasis. The multivariate analysis identified five independent predictors: non-mass lesions >2.4 cm on ultrasonography (odds ratio [OR] 2.84, 95% confidence interval [CI] 1.02-7.95, p=0.047), comedo-type histology (OR 6.89, 95% CI 1.89-25.08, p<0.01), solid-type histology (OR 7.97, 95% CI 2.08-30.49, p<0.01), palpable mass (OR 2.63, 95% CI 1.05-6.64, p=0.04), and bloody nipple discharge (OR 4.61, 95% CI 1.20-17.66, p=0.02). These five predictors were associated with invasion on final pathology and may help select candidates for sentinel node biopsy. |

| 抄録 | We elucidate the fate of cases clinically suspected of carcinoma in situ (Cis) of the upper tract with serial ureteroscopy. Of 143 patients who underwent ureteroscopy for suspected upper tract urothelial carcinoma (UTUC) between January 2008 and February 2016, 12 cases with consistently positive urine cytology and poorly detectable upper-tract malignancies by imaging were reviewed. In these 12 patients, 19 ureteroscopy procedures (25 renal units) were performed. Vesical random biopsy was performed before the 1st ureteroscopy to exclude malignancy of the bladder in all 12 cases. Median follow-up was 42 (13-67) months. Positive biopsy results at the 1st ureteroscopy were obtained in 3 (25%) patients and all were diagnosed wth Cis of the upper tract. Two (17%) of 9 patients who were negative or inconclusive at the 1st ureteroscopy were finally diagnosed as UTUC, but plural ureteroscopy procedures were needed for the diagnoses in both. Carcinoma of the bladder appeared in 5 (42%) patients during follow-up, despite the earlier ruling out of vesical malignancy. Four (33%) of those 5 patients never developed upper-tract urothelial carcinoma during follow-up. Caution is required before undertaking radical surgery for cases clinically suspected of Cis of the upper tract. In our experience, only 42% of such patients developed UTUC; another 33% eventually developed carcinoma of the bladder without UTUC. |

| 抄録 | Anticancer drugs induce cell-cycle arrest and apoptosis not only in tumor cells, but also in immune cells. However, many preclinical and clinical findings show that some chemotherapeutic agents can improve the antitumor efficacy of immunotherapy. We immunohistochemically analyzed the degree of immune cell infiltration and the relevance of programmed cell death 1 ligand-1 (PD-L1) expression in surgically resected oral squamous cell carcinoma (OSCC) specimens from patients who had undergone pretreatment with certain chemotherapies and other patients without pretreatment. We divided the patients into the group of neoadjuvant chemotherapy (NAC) patients (n=8) and the nNAC (without NAC) patient group (n=10). We observed that NAC induced infiltrations of CD4, CD8 T cells and CD56 NK cells into the tumor microenvironment. Decreased numbers of Tregs and PD-1-positive cells were observed in the NAC group. No significant difference was observed in the degree of immune-cell infiltration between the patient groups except for CD56 NK cells in the stroma and PD-1 cells in cancer nests. Eighty percent of the nNAC specimens showed intermediate-to-strong PD-L1 protein expression, whereas 75% of the NAC specimens showed down-regulation of the PD-L1 protein, indicating the effectiveness of the chemotherapeutic treatment before surgery. |

| 抄録 | We evaluated how exposure to airborne volatile organic compounds emitted from a plastic recycling facility affected nearby residents, in a cross-sectional study. Individuals>10 years old were randomly sampled from 50 households at five sites and given questionnaires to complete. We categorized the subjects by distance from the recycling facility and used this as a proxy measure for pollutant exposure. We sought to improve on a preceding study by generating new findings, improving methods for questionnaire distribution and collection, and refining site selection. We calculated the odds of residents living 500 or 900 m away from the facility reporting mucocutaneous and respiratory symptoms using a reference group of residents 2,800 m away. Self-reported nasal congestion (odds ratio=3.0, 95% confidence interval=1.02-8.8), eczema (5.1, 1.1-22.9), and sore throat (3.9, 1.1-14.1) were significantly higher among residents 500 m from the facility. Those 900 m away were also considerably more likely to report experiencing eczema (4.6, 1.4-14.9). Air pollution was found responsible for significantly increased reports of mucocutaneous and respiratory symptoms among nearby residents. Our findings confirm the effects of pollutants emitted from recycling facilities on residents’ health and clarify that study design differences did not affect the results. |

| 抄録 | Vascular dysfunction has been reported in women with recurrent pregnancy loss (RPL). We investigated the severity of vascular dysfunction in non-pregnant women with RPL and its correlation with anti-heat shock protein (HSP) antibodies that are known to induce arteriosclerosis. We measured the serum anti-HSP60 antibodies, anti-HSP70 antibodies, and anti-phospholipid antibodies (APA) in 68 women with RPL and 29 healthy controls. Among the women with RPL, 14 had a diagnosis of antiphospholipid syndrome (APS), and in the remaining 54, the causes for RPL were unexplained. Compared to the controls, the brachial-ankle pulse wave velocity (baPWV), carotid augmentation index (cAI), and uterine artery pulsatility index (PI) were all significantly higher in the women with both APS and unexplained RPL. Compared to the controls, the anti-HSP60 antibody levels were significantly higher in the APA-positive group of women with unexplained RPL, and the anti-HSP70 antibody levels were significantly higher in APS and APA-positive group of women with unexplained RPL. However, the anti-HSP60 and anti-HSP70 antibody levels did not correlate with the values of baPWV or cAI. Our results demonstrated anti-HSP60 and anti-HSP70 antibodies are increased in women with unexplained RPL. Further studies are needed to elucidate the roles of anti-HSP antibodies and their pathophysiology in unexplained RPL. |

| 抄録 | Electroencephalogram (EEG) data include broadband electrical brain activity ranging from infra-slow bands (< 0.1 Hz) to traditional frequency bands (e.g., the approx. 10 Hz alpha rhythm) to high-frequency bands of up to 500 Hz. High-frequency oscillations (HFOs) including ripple and fast ripple oscillations (80-200 Hz and>200 / 250 Hz, respectively) are particularly of note due to their very close relationship to epileptogenicity, with the possibility that they could function as a surrogate biomarker of epileptogenicity. In contrast, physiological high-frequency activity plays an important role in higher brain functions, and the differentiation between pathological / epileptic and physiological HFOs is a critical issue, especially in epilepsy surgery. HFOs were initially recorded with intracranial electrodes in patients with intractable epilepsy as part of a long-term invasive seizure monitoring study. However, fast oscillations (FOs) in the ripple and gamma bands (40-80 Hz) are now noninvasively detected by scalp EEG and magnetoencephalography, and thus the scope of studies on HFOs /FOs is rapidly expanding. |
