抄録 Primary Sjögren’s syndrome (SS) is an autoimmune disease that usually affects the exocrine glands in mid-dle-aged women. Fifteen percent of SS patients experience severe systemic extraglandular complications, and pleuritis is one of the rare complications of SS. We report the case of an elderly Japanese man who initially pre-sented with a prolonged fever and chest pain and was finally diagnosed with primary SS-associated pleuritis. Of the nine reported cases of primary SS that initially presented with pleuritis, up to six cases were elderly males. This case highlights the complication of pleuritis among elderly males with primary SS.

抄録 A 67-year-old woman underwent polypectomy for a tumor at the descending colon. Pathologically, the tumor was diagnosed as adenocarcinoma with an invasion of 2000 μm. Computed tomography showed a swollen paracolic lymph node and a mass lesion in the presacral space. Magnetic resonance imaging revealed a multio-cular cystic lesion. On diagnosis of descending colon cancer and tailgut cyst, she underwent synchronous lapa-roscopic resection. Histopathologically, the colon cancer was diagnosed as pT1bN1M0, pStage IIIa. The pre-sacral cystic lesion was diagnosed as a nonmalignant tailgut cyst with negative surgical margin. The patient is currently doing well without recurrence at 28 months.

抄録 Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a genetically mediated cardiomyopathy charac-terized by progressive myocardial loss of the right ventricle and its replacement by fibrofatty tissue, causing dyskinesia, aneurysm, and/or arrhythmia. The prevalence of ARVC is estimated to be 1 in 2,000-5,000, with the condition accounting for up to 20% of sudden cardiac deaths in individuals < 35 years old. This report describes the case of 61-year-old Japanese who was diagnosed with ARVC after cardiac arrest (CA) and successful resusci-tation. After the sudden CA, the restoration of spontaneous circulation was achieved with appropriate resusci-tation, followed by the introduction of target temperature management in the intensive care unit. He was diag-nosed with ARVC based on angiography and histology results. An ICD (implantable cardioverter-defibrillator) was implanted, and he was discharged without neurological sequelae 1 month post-CA. ARVC is an important cause of sudden CA, and successfully resuscitated patients with right ventricular dilation should undergo testing to rule out ARVC.

抄録 Ebola virus disease (EVD) is a highly contagious and fatal disease in humans. Healthcare providers (HCPs) are often at the frontline of epidemics and can thus be in jeopardy of contracting EVD. Sudan is at a great risk of an EVD outbreak, as it borders countries that experienced EVD outbreaks. It is therefore imperative in Sudan to assess the HCPs’ awareness and knowledge, attitude, and practice (KAP) about EVD for its control and man-agement and for preparedness. A KAP survey was conducted among 387 HCPs (physicians, nurses and labora-tory technicians) in the three main tertiary hospitals in Khartoum, Sudan. The majority of the survey respon-dents (54.5%) were females, < 30 years old (76.3%), and single (77.4%). Most (94%) had heard about EVD, 62% from classical media. Only 14% had received education or training regarding EVD. About 40% reported being adherent to universal precautions and 72% were willing to deal with EVD patients under safety precau-tions. Only 10% knew of any available standard national guidelines for EVD. Nearly half of the HCPs (47%) rated the potential risk of an EVD outbreak in Sudan as high, and 52% rated health authorities’ effort against it as weak. These findings revealed the HCPs’ insufficient knowledge of EVD and the necessary universal precau-tions. This lack of knowledge would negatively affect the HCPs’ preparedness toward any potential EVD out-break. There is a dire need to train HCPs in Sudan on the management of EVD, including preventive and con-trol measures.

抄録 Instances of traumatic brain injury (TBI) in the elderly have been increasing along with the aging of popula-tions. In the present study, we examined the effect of aging on long-term multidisciplinary in-patient rehabili-tation efficacy after TBI. Sixty-three patients with physical and cognitive impairments after TBI were enrolled in this study. Patients were divided into 4 age groups (≤ 24, 25-44, 45-64, ≥ 65 years) and the clinical charac-teristics and rehabilitation efficacy of each age group were determined. Functional disability was evaluated using motor and cognitive Functional Independence Measure (FIM) scores. Rehabilitation efficacy was assessed by FIM gains during rehabilitation and compared among the groups. There were no statistically significant dif-ferences in motor and cognitive FIM gains among the age groups. However, cognitive FIM gain was limited in a subset of ≥ 65 patients, and initial cognitive measures could not predict cognitive FIM improvement. These results indicate that chronological age is insufficient to accurately predict rehabilitation efficacy in older TBI patients, and that such patients should be considered candidates for intensive rehabilitation programs based on these results. Accurate prognostication of rehabilitation efficacy with continuing data collection is important when using rehabilitation resources for older TBI patients.

抄録 The characteristics of gastric polyps in patients with Peutz-Jeghers (PJ) syndrome (PJS) have not been fully investigated. The objective of this study was to reveal the endoscopic and pathologic findings of gastric polyps in patients with PJS. We reviewed 11 patients with PJS treated at 6 institutions, and summarized the endo-scopic and pathologic features of their gastric polyps. The polyps were mainly classified into 2 types: (i) soli-tary or sporadic polyps > 5 mm, reddish in color with a sessile or semi-pedunculated morphology (n = 9); and (ii) multiple sessile polyps ≤ 5 mm with the same color tone as the peripheral mucosa (n = 9). Patients who underwent endoscopic mucosal resection for polyps > 5 mm were diagnosed with PJ polyps (n = 2), whereas those who underwent biopsy were diagnosed with hyperplastic polyps. Polyps ≤ 5 mm were pathologically diagnosed as fundic gland polyps or hyperplastic polyps. This study revealed that patients with PJS present with 2 types of polyps in the stomach. Endoscopic mucosal resection of polyps > 5 mm seems necessary for the pathologic diagnosis of PJ polyps.

抄録 Bendamustine plus rituximab (B-R) is an effective therapy for relapsed or refractory (r/r) low-grade B-cell lymphoma (LGBCL) and mantle cell lymphoma (MCL); however, clinical data from Japanese patients treated with B-R therapy are limited. We retrospectively evaluated the efficacy and safety of B-R therapy in 42 patients who received B-R therapy at our hospital for r/r LGBCL and MCL. All patients received intravenous (IV) ritux-imab 375 mg/m2 on day 1 and IV bendamustine 90 mg/m2 on days 2 and 3 every 28 days for up to 6 cycles. The common histologic subtypes were follicular lymphoma (n = 29, 70%), marginal zone lymphoma (n = 6, 14%), and MCL (n = 5, 12%). The overall response rate was 93%, with 62% complete response and complete response unconfirmed. The median progression-free survival (PFS) was 38 months (95% confidence interval [CI], 24.6 to not reached [NR]), and the median overall survival (OS) was 80 months (95% CI, 60.7 to NR). Patients receiving a cumulative dose of bendamustine ≥ 720 mg/m2 showed a significantly longer PFS and OS. Grade 3/4 adverse events (≥ 10%) included neutropenia (55%), lymphopenia (69%), and nausea (24%). B-R therapy was effective and well tolerated, and the cumulative dose of bendamustine was associated with a favorable outcome.

抄録 In high myopia, eye dislocation due to increased globe volume or tight orbital volume causes acquired esotro-pia. GOR (globe/orbit volume ratio), an indicator of the degree of progression of this pathology, was investi-gated the relationships among easily obtained clinical parameters. In this retrospective study, 20 eyes from 10 acquired esotropia patients with high myopia but without abduction limitations were examined. The mean age of the patients was 63.7 ± 8.2 years (mean ± standard deviation). Volumes were measured on the three-dimen-sional fast imaging employing steady-state acquisition magnetic resonance imaging images using the vol-ume-measurement function. Correlations between GOR and the displacement angle of the globe (DA), axial length (AL), and equatorial diameter (ED) were investigated. Mean DA, AL, ED, and GOR values were 107.5 ± 8.5°, 28.86 ± 1.92 mm, 25.00 ± 1.16 mm, and 0.36 ± 0.05, respectively. Only AL was correlated with GOR (p < 0.0001, R2 = 0.6649); DA (p = 0.30, R2 = 0.0633) and ED (p = 0.91, R2 = 0.0008) were not. AL was the only clinically available parameter to indicate globe/orbit volume imbalances in acquired esotropia with high myopia but without abduction limitation. AL may be important for the clinical assessment of the progression of this pathology.

抄録 Early diagnosis and therapy are important in a cesarean scar pregnancy (CSP), which can cause uterine rupture with resultant massive bleeding. However, there are some reports of CSPs continued to term. The optimal management of CSPs remains unclear; therefore, we investigated the clinical courses of CSPs diagnosed and treated at perinatal institutions in the Chugoku and Shikoku regions of Japan. We enrolled 60 women diag-nosed with CSP at 21 institutions from January 2006 to December 2015. Of the 60 women diagnosed with CSP, 57 were treated. Pregnancy was terminated in 48 women and continued in 9. Thirteen women underwent transabdominal hysterectomy; they experienced no postoperative complications or allogeneic blood transfu-sion. Nine women received therapies such as dilation and curettage, and 26 received non-surgical therapies such as methotrexate and topical administration of potassium chloride. Among 9 women who chose to con-tinue with their CSP, 7 successfully delivered newborns, 2 had uterine ruptures in the second trimester, and all women required transabdominal hysterectomy. Diagnosis and therapy in the first trimester of pregnancy are important in the management strategy of a CSP. When continuing a CSP, the risk of uterine rupture and trans-abdominal hysterectomy must be considered.

抄録 This study aimed to evaluate whether there are differences in the attitudes and practices of cancer pain manage-ment between medical oncologists and palliative care physicians. An online nationwide survey was used to collect responses from board-certified medical oncologists and palliative care physicians in Japan. The survey questionnaire comprised 30 questions. The differences in responses between medical oncologists and palliative care physicians were examined. Out of the 1,227 questionnaires sent, 522 (42.5%) were returned. After apply-ing the exclusion criteria, 445 questionnaires (medical oncologists: n = 283; palliative care physicians: n = 162) were retained for analysis. Among the questions about potential barriers to optimal cancer pain man-agement, both medical oncologists and palliative care physicians considered the reluctance of patients to take opioids due to fear of adverse effects as the greatest barrier. Significantly different ratings between medical oncologists and palliative care physicians were observed on 5 of the 8 questions in this area. Significantly differ-ent ratings were observed for all questions concerning pain specialists and their knowledge. For effective cancer pain management, it is important to account for differences in attitudes and practice between medical oncolo-gists and palliative care physicians.

抄録 The treatment of medial meniscus posterior root tears (MMPRTs) has evolved to include a variety of repair strategies. This study investigated the location of the articular cartilage degeneration during second-look arthroscopy after transtibial pullout repair with a modified Mason-Allen suture using FasT-Fix (F-MMA) in 22 patients with MMPRTs. Second-look arthroscopy was performed approximately 1 year postoperatively to eval-uate the healing status of the medial meniscus (MM). Articular cartilage degeneration was assessed using the International Cartilage Repair Society grade at primary surgery and again at second-look arthroscopy. Articular surfaces of the medial/lateral femoral condyles, the medial/lateral tibial plateaus, the patella and the trochlea were divided into several subcompartments (MF 1-9, LF 1-9, MT 1-5, LT 1-5, P 1-9, T 1-3). Clinical evaluations used the Japanese Knee Injury and Osteoarthritis Outcome, Lysholm, and International Knee Documentation Committee scores. Second-look arthroscopic findings showed complete healing of the MM posterior root in all patients. Significant differences between pullout repair and second-look arthroscopy were observed for MF 2 and 4, LF 7, and P 7. All clinical outcomes were improved. Our results indicate that this technique improves clinical outcomes postoperatively and may prevent the progression of cartilage degenera-tion on the loading surface of the medial knee compartment.

抄録 Human RAD17, as an agonist of checkpoint signaling, plays an essential role in mediating DNA damage. This hospital-based case-control study aimed to explore the association between RAD17 rs1045051, a missense sin-gle nucleotide polymorphism (SNP), and prostate cancer risk. Subjects were 358 prostate cancer patients and 314 cancer-free urology patients undergoing treatment at the Zhujiang Hospital of Southern Medical University in China. RAD17 gene polymorphism rs1045051 was evaluated by the SNaPshot method. Compared with the RAD17 gene polymorphism rs1045051 AA genotype, there was a higher risk of prostate cancer for the CC gen-otype (adjusted odds ratio [AOR] = 1.731, 95% confidence interval [95%CI] = 1.031−2.908, p = 0.038). Compared with the A allele, the C allele was significantly associated with the disease status (AOR = 1.302, 95%CI = 1.037−1.634, p = 0.023). All these findings indicate that in the SNP rs1045051, both the CC genotype and C allele may have a substantial influence on the prostate cancer risk.

抄録 Epiretinal membrane (ERM) is a common retinal disease characterized by cellular proliferation and metaplasia that lead to the formation of a pathological fibrocellular membrane immediately superjacent to the inner retinal surface. The vast majority of ERMs are considered idiopathic. However, ERM formation can result from various primary intraocular diseases, including retinal breaks and detachment, retinal vascular diseases, and vitreoretinal inflammatory conditions. Although ERMs are generally asymptomatic or cause mild metamorphopsia and/or a modest decrease in visual acuity, some can cause severe macular distortion and macular edema, resulting in significantly impaired function. Surgical removal of ERM is the only treatment, and improvements in vitrectomy systems have enabled less invasive treatment. However, there are currently no standardized criteria for ERM surgery, and the indications for surgery are determined from the patient’s subjective symptoms. Another problem with ERM surgery is that not all patients show satisfactory postoperative recovery of visual function. Thus, further research is needed to determine the criteria for ERM surgery and methods to improve the postoperative prognosis.

抄録 We report a 62-year-old male with metastatic fumarate hydratase-deficient renal cell carcinoma (FH-deficient RCC) without fumarate hydratase (FH) mutation (FH-deficient–like RCC). The International Metastatic RCC Database Consortium risk score was intermediate, and immunotherapy with nivolumab and ipilimumab (Ipi/ Nivo) was initiated. Four cycles of Ipi/Nivo and 5 cycles of nivolumab resulted in a complete response of the metastases. Hypophysitis occurred as an immune-related adverse event after four cycles of Ipi/Nivo. The prognosis of patients with FH-deficient RCC is generally poor. Few reports of FH-deficient RCC successfully treated with Ipi/Nivo have been published. Ipi/Nivo can be effective for treating FH-deficient RCC.

Amo Type Case Report
備考 We report an extremely rare case of a centenarian with acute appendicitis that was successfully managed via emergent surgery. A 109-year-old woman was referred to Daiichi Towakai Hospital with a high fever and nausea. She presented with peritoneal irritation, and computed tomography showed a swollen appendix with intraluminal fecolith. She was diagnosed with acute appendicitis and underwent appendectomy, which was performed via an open approach under spinal anesthesia. The patient’s postoperative course was uneventful. As for treatment planning for centenarians, comprehensive and exhaustive discussions with the patient and family members should be encouraged under the principals of narrative medicine.|

抄録 Osteocalcin (OC) is inversely related to body fat distribution and fasting glucose levels. We sought to observe the effect of OC on fat distribution and subclinical atherosclerosis as measured by carotid intima-media thickness (CIMT) in premenopausal obese women. In this prospective observational study, totally, 73 premenopausal obese women (aged 17-55 years) and 53 healthy women (aged 20-50 years) with normal weight were included as controls. Anthropometric measurements, total fat and fat ratio, insulin, fasting blood glucose, and OC levels were estimated. Ultrasonography was used to assess fat distribution, and fat thickness was measured in 4 regions. Subcutaneous fat (SCF), visceral fat (VF), and preperitoneal fat (PPF) thicknesses were considerably higher in obese subjects (p<0.01) than healthy controls, while OC levels were significantly lower. No correlation was observed between OC levels and SCF, VF, or PPF. In a multiple regression analysis, OC was significantly positively associated with SCF (p=0.04, Beta=0.284). No associations were observed between OC levels and VF, PPF, or CIMT. A significant association was observed between parathyroid hormone (PTH) and VF (p=0.021, Beta=0.284), and vitamin D levels were inversely associated with VF (p=0.002, r=−0.366). OC levels were lower in premenopausal obese women than normal-weight healthy controls, but OC exhibited no correlation with VF or PPF, and only a weak positive association with SCF. Additionally, VF was positively correlated with PTH and inversely correlated with vitamin D. These results suggest that OC may be an early indicator of lipid accumulation in te subcutaneous area and development of atherosclerosis.

抄録 Hepatic oxidative stress plays an important role in the pathogenesis of several acute liver diseases, and free heme is thought to contribute to endotoxemia-induced acute liver injury. The heme oxygenase 1 (HO-1) gene is upregulated and the δ-aminolevulinate synthase (ALAS1) gene is downregulated in the rat liver following lipopolysaccharide (LPS) treatment. BTB and CNC homology 1 (Bach1) is a heme-responsive transcription factor that normally represses HO-1 expression. In this study, we evaluated the changes in HO-1, ALAS1, and Bach1 expression and nuclear Bach1 expression in rat livers following intravenous LPS administration (10 mg/kg body weight). LPS significantly upregulated HO-1 mRNA and downregulated ALAS1 mRNA in the rat livers, suggesting that hepatic free heme concentrations are increased after LPS treatment. Bach1 mRNA was strongly induced after LPS injection. In contrast, nuclear Bach1 was significantly but transiently decreased after LPS treatment. Rats were also administered hemin (50 mg/kg body weight) intravenously to elevate heme concentrations, which decreased nuclear Bach1 levels. Our results suggest that elevated hepatic free heme may be associated with a decline of nuclear Bach1, and induction of Bach1 mRNA may compensate for the decreased nuclear Bach1 after LPS treatment in the rat liver.

抄録 Perioperative dose-dense chemotherapy (DDCT) with pegfilgrastim (Peg) prophylaxis is a standard treatment for high-risk breast cancer. We explored the optimal timing of administration of 3.6 mg Peg, the dose approved in Japan. In the phase II feasibility study of DDCT (adriamycin+cyclophosphamide or epirubicin+cyclophosphamide followed by paclitaxel) for breast cancer, we investigated the feasibility, safety, neutrophil transition, and optimal timing of Peg treatment by administering Peg at days 2, 3, and 4 post-chemotherapy (P2, P3, and P4 groups, respectively). Among the 52 women enrolled, 13 were aged > 60 years. The anthracycline sequence was administered to P2 (n=33), P3 (n=5), and P4 (n=14) patients, and the taxane sequence to P2 (n=38) and P3 (n=6) patients. Both sequences showed no interaction between Peg administration timing and treatment discontinuation, treatment delay, or dose reduction. However, the relative dose intensity (RDI) was significantly different among the groups. The neutrophil count transition differed significantly among the groups receiving the anthracycline sequence. However, the neutrophil count remained in the appropriate range for both sequences in the P2 group. The timing of Peg administration did not substantially affect the feasibility or safety of DDCT. Postoperative day 2 might be the optimal timing for DDCT.

抄録 We assessed the role of 18F-FDG PET/CT texture indices for the differentiation of squamous cell carcinoma (SCC) and non-Hodgkin’s lymphoma (NHL) in the oropharynx. 18F-FDG PET/CT data for 27 patients with SCC and 25 patients with NHL in the oropharynx were investigated. The maximum standardized uptake value (SUVmax), metabolic tumor volume (MTV), total lesion glycolysis (TLG), and six texture indices (homogeneity, entropy, short-run emphasis, long-run emphasis, low gray-level zone emphasis [LGZE], and high graylevel zone emphasis [HGZE]) were derived from PET images. PET/CT parameters of the SCC patients were compared with those of the NHL patients. The diagnostic accuracy of the indices for differentiating SCC from NHL was calculated by a receiver operating characteristic curve analysis. 18F-FDG uptake in the oropharynx was observed in all of the patients. The SUVmax, MTV, and TLG did not differ significantly between the SCC and NHL groups, but two of the six texture indices (LGZE [p=0.004] and HGZE [p=0.03]) showed significant differences between the groups. LGZE was the best discriminative index for the differentiation of SCC and NHL (55.6% sensitivity, 88.0% specificity). The LGZE and HGZE texture indices derived from 18F-FDG PET/CT images may be useful in differentiating SCC and NHL in the oropharynx.
