抄録 Fitz-Hugh-Curtis syndrome is characterized by an inflammation of the perihepatic capsules associated with pelvic inflammatory disease. The typical symptom is severe right upper quadrant abdominal pain. We report a patient with Fitz-Hugh-Curtis syndrome who presented with an atypical chief complaint of right-side chest pain unaccompanied by symptoms specific to pelvic inflammatory disease. This case indicates that Fitz-Hugh-Curtis syndrome should be considered in the differential diagnosis of right-side chest pain in young women, because early diagnosis and treatment of the disease are essential to prevent chronic complications.

抄録 Esophagogastroduodenoscopy revealed small duodenal lesions in a 56-year-old Japanese man and a 92-year-old Japanese woman with stage IV follicular lymphoma. Magnifying endoscopy examination revealed tiny white deposits in the second duodenal portion of the former patient and slightly enlarged duodenal villi in the latter. In both cases, biopsy revealed infiltration of follicular lymphoma cells and incipient formation of neoplastic follicles. Here, we discuss the usefulness of magnifying endoscopy and narrow-band imaging for the detection of small duodenal lesions in follicular lymphoma cases.

抄録 Human congenital anomalies provide information that contributes to the understanding of developmental mechanisms. Here we report bilateral optic nerve aplasia (ONA) with microphthalmia in the autopsy of the cadaver of a 70-year-old Japanese female. The gross anatomical inspection of the brain showed a cotton thread-like cord in the presumed location of the optic nerve tract or chiasm. Histologically, no neural retina, optic nerve bundle or retinal central vessels were formed in the eye globe, and the retinal pigment cells formed rosettes. The cornea, iris, and lens were also histologically abnormal. Immunohistochemically, no retinal cells expressed beta III tubulin, and Pax6-immunoreactive cells were present in the ciliary non-pigmented epithelial cells. This case of ONA could be attributed to the agenesis of retinal projection neurons as a sequel to the disruption of neural retina development. The neural retina formation would coordinate the proper development of ocular tissues.

抄録 Using the Postgastrectomy Syndrome Assessment Scale (PGSAS)-45, we compared the surgical outcomes and the quality of life (QOL) between patients undergoing limited gastrectomies and those undergoing conventional gastrectomies. In Oomoto Hospital between January 2004 and December 2013, a total of 124 patients who met the eligibility criteria were enrolled. Using the main outcome measures of PGSAS-45, we compared 4 types of limited gastrectomy procedures (1/2 distal gastrectomy [1/2DG] in 21 patients; pylorus-preserving gastrectomy [PPG] in 15 patients; segmental gastrectomy [SG] in 26 patients; and local resection [LR] in 13 patients) with conventional gastrectomy (total gastrectomy [TG] in 24 patients and 2/3 or more distal gastrectomy [WDG] in 25 patients). The TG group showed the worst QOL in almost all items of the main outcome measures. The 1/2DG, PPG, and SG groups showed better QOL than the WDG group in many of the main outcome measures, including the body weight ratio, total symptom score, ingested amount of food per meal, and the dissatisfaction for daily life subscale. The LR group showed a better intake of food than the 1/2DG, PPG, and SG groups. The body weight ratio of the LR group was better than that of the SG group. Diminished gastric resection preserved better QOL in patients with early gastric cancer.

抄録 Membrane transport probably participates in the lifecycle of hepatitis C virus (HCV). Rab proteins are essential host factors for HCV RNA replication, but these proteins’ roles in other steps of the HCV lifecycle are not clear. The tight junction (TJ) plays a key role in HCV infection. Rab13 regulates the endocytic recycling of the TJ-associated proteins. Here we investigated whether Rab13 is involved in the HCV entry step. We used HuH-7-derived RSc cells and Li23-derived D7 cells. To evaluate the effect of Rab13 in HCV infection, we transfected the cells with siRNA targeting Rab13 before HCV infection. The down-regulation of Rab13 inhibited HCV infection. The D7 cells had showed a greater inhibitory effect against HCV infection compared to that in the RSc cells by Rab13 knockdown. Next, to evaluate the effect of Rab13 after infection, we inoculated the cells with HCV before transfection of the siRNA. The down-regulation of Rab13 did not show any effects after HCV infection. We further examined whether Rab13 would influence HCV RNA replication by using HCV replicon-harboring cells. The results revealed that Rab13 did not affect the step of HCV RNA replication. These results suggest that Rab13 plays an important role in the step of HCV entry.

抄録 Molecular and epidemiologic investigations suggest a causal role for human papillomavirus (HPV) in anogenital cancers. This study identified oncogenic HPV genotypes in anogenital cancers among men and women in a 2013 cross-sectional descriptive study in Myanmar. In total, 100 biopsy tissues of histologically confirmed anogenital cancers collected in 2008-2012 were studied, including 30 penile and 9 anal cancers from Yangon General Hospital and 61 vulvar cancers from Central Women's Hospital, Yangon. HPV-DNA testing and genotyping were performed by polymerase chain reaction-restriction fragment length polymorphism. Overall, 34% of anogenital cancers were HPV-positive. HPV was found in 44.4% of anal (4/9), 36.1% of vulvar (22/61), and 26.7% of penile (8/30) cancers. The most frequent genotypes in anal cancers were HPV 16 (75%) and 18 (25%). In vulvar cancers, HPV 33 was most common (40.9%), followed by 16 (31.8%), 31 (22.7%), and 18 (4.6%). In penile cancers, HPV 16 (62.5%) was most common, followed by 33 (25%) and 18 (12.5%). This is the first report of evidencebased oncogenic HPV genotypes in anogenital cancers among men and women in Myanmar. This research provides valuable information for understanding the burden of HPV-associated cancers of the anus, penis, and vulva and considering the effectiveness of prophylactic HPV vaccination.

抄録 Vertical sacral fracture is one of the most difficult fractures to treat. Posterior fixation using spinal dual rods is a novel method for treating this fracture, but its biomechanical strength has not yet been reported. The aim of this study was to evaluate the biomechanical strength produced by posterior fixation using spinal instrumentation. Sacral fractures were created in eight pelvic bone models and classified into a posterior plate fixation group [P group, n=4] and a spinal instrumentation group [R group, n=4]. The biomechanical strength was tested by pushing down on the S1 vertebra from the top. The mean maximum loads were 1,057.4 N and 1,489.4 N in the P and R groups, respectively (p=0.014). The loads applied to the construct at displacements of 5mm and 7.5mm from the start of the universal testing machine loading were also significantly higher in the R group. The mean stiffness levels in the P and R groups were 88.3N/mm and 119.6N/mm, respectively (p=0.014). Posterior fixation using spinal instrumentation is biomechanically stronger than conventional posterior plate fixation. This procedure may be the optimal method for treating unstable sacral fracture fixation.

抄録 Total hip arthroplasty (THA) is an established treatment approach with which good recovery is expected in patients. However, the postoperative satisfaction of THA patients, and factors that affect their treatment outcomes are unclear. We investigated 125 Japanese patients who underwent a primary THA between January 2011 and August 2013. The posterolateral (PL) and muscle-sparing anterolateral (AL) surgical approaches were used. THA outcomes were evaluated using the Short Form-36 (SF-36) at preoperatively and 1 month, 3 months, 6 months, and 1 year postoperatively. Approach-based comparisons demonstrated a significantly higher mean score for physical functioning after 6 months, role physical at 1 year, and social functioning at 1 year in the AL group. No significant difference was observed for other subscale scores at any survey period. The age-based comparison often indicated significant increases of subscale scores in the younger patient group. Weight-based comparisons were not observed for any of the 8 subscales at any survey period. Surgical approach was not a factor affecting the patients’ postoperative quality of life, and the AL approach was not superior to the other surgical approaches involving myotenotomy. Moreover, the THA treatment outcomes were better in the younger patients, and obesity did not affect the outcomes.

抄録 The mechanisms of hepatitis C virus (HCV)-associated hepatocarcinogenesis and disease progression are unclear. We previously observed that the expression level of carboxypeptidase B2 (CPB2) gene was remarkably suppressed by persistent HCV RNA replication in human hepatoma cell line Li23-derived cells. The results of the present study demonstrated that the CPB2 expression in patients with chronic hepatitis C was inversely correlated with several risk factors of hepatic fibrosis or steatosis, although ectopic CPB2 expression did not suppress the expression of fibrogenic or lipogenic genes. The suppressed CPB2 expression was restored by treatment with 5-azacytidine. To clarify the mechanism underlying this phenomenon, we analyzed the CPB2 promoter, and the results revealed that (1) hepatocyte nuclear factor 1 (HNF1), especially HNF1α, was essential for the CPB2 promoter, and (2) CPB2 promoter was not methylated by persistent HCV RNA replication. The expression levels of HNF1α and HNF1β were also not changed by persistent HCV RNA replication. These results suggest the existence of 5-azacytidine-inducible or -reducible unknown factor(s) that can control the CPB2 expression. To evaluate this idea we performed a microarray analysis, and several gene candidates corresponding to the suggested factor(s) were identified.

抄録 In minimally invasive partial nephrectomy (MIPN), it is important to preoperatively predict the degree of difficulty of tumor resection. When severe adhesions occur between the renal capsule and perinephric adipose tissue, detachment can be difficult. Preoperative prediction of adhesion is thought to be useful in the selection of surgical procedure. Subjects were 63 patients of a single surgeon who had received MIPN between April 2008 and August 2013 at Okayama University Hospital. Of these patients, this study followed 47 in whom the presence or absence of adhesions between the renal capsule and perinephric adipose tissue was confirmed using intraoperative videos. Data collected included: sex, BMI, CT finding (presence of fibroids in perinephric adipose tissue), comorbidities and lifestyle. Adhesion was observed in 7 patients (14.9%). The mean operative time was 291.6min in the adhesion group, and 226.3min in the group without. The increased time in the adhesions group was significant (p<0.05). Predictive factors were a positive CT finding for fibroid structure and comorbidity of hypertension (p<0.05). In MIPN, difficulty of surgery can be affected by the presence of adhesion of the perinephric adipose tissue. Predicting such adhesion from preoperative CT is thus important.

抄録 Pregnant women with uterine leiomyomas may experience anxiety toward their pregnancies and unfavorable feelings toward their infants. From March to July 2010, we distributed anonymous self-recorded questionnaires to 200 pregnant women who visited Okayama Central Hospital for an antenatal check-up after informed consent was provided, and 132 women (23 pregnant women with uterine leiomyomas) were included in our study. Among the multiparous women in their first trimester, the women with uterine leiomyomas had a higher rate of anxiety than those without uterine leiomyomas. ʻAvoidanceʼ scores on the Feeling Toward the Baby Scale were significantly higher in the leiomyoma group. The conflict index scores tended to be higher in the leiomyoma group. A multivariate analysis revealed no factors associated with trait-anxiety scores, whereas high state-anxiety scores were correlated with low age;however, there was no correlation between these scores and uterine leiomyomas. Although no factors were associated with State-Trait Anxiety Inventory (STAI) and approach scores toward the baby, avoidance and conflict index scores were associated with the existence of uterine leiomyomas. In pregnant women with uterine leiomyomas, efforts should be made to reduce anxiety in the first trimester, and support should be provided to help these women develop positive feelings toward their babies.

抄録 We present the case of a 77-year-old Japanese man diagnosed with lung squamous cell carcinoma with mediastinal lymph node metastasis. He was treated with induction chemoradiotherapy for T1bN2M0 stage IIIA disease. Considering his age, we selected S-1 as the chemotherapeutic drug. Observing an objective response with no severe adverse events, we performed a left upper lobectomy with sleeve resection of the pulmonary artery. No residual tumor cells were found in the resected specimens, and no critical complication was observed in the clinical course. This case suggests that induction chemoradiotherapy using S-1 combined with concurrent radiation followed by surgery can be a therapeutic option for elderly patients with locally advanced non-small-cell lung cancer.
