    No full text
    A 78-year-old woman presented with fever, severe abdominal pain, and distension. She had been institutionalized for depression and senile dementia. Laboratory examinations disclosed a leucocytosis (WBC: 12 500/μL) and elevated levels of serum C-reactive protein (2.8 mEq/L). Diagnosis of acute cecal volvulus was made from a “coffee bean sign” on an abdominal computed tomography and a “beak sign” on a gastrographin enema. An emergent laparotomy confirmed the diagnosis and an ileo-colectomy with primary anastomosis was carried out. The patient recovered after intensive respiratory care and fluid therapy, and then returned to her former institution. A review of Japanese literature disclosed that: (1) a marked increase of aged patients with mental disability presenting with cecal volvulus, (2) adoption of ileo-colectomy as the standard surgical procedure, and (3) improved survival of the patients, were observed in the last decade

    Acute cholecystitis is an infectious disease of the gallbladder caused mainly by Escherichia coli, Klebsiella, and Enterococcus species. Streptococcus gallolyticus subsp. pasteurianus, previously known as Streptococcus bovis biotype II/2, rarely causes endocarditis, meningitis, and septicemia, mainly in children. Biliary tract infections by Streptococcus gallolyticus subsp. pasteurianus are extremely rare. There have been no reports of cases in Japan. Here, we describe the first case in Japan of acute calculous cholecystitis caused by Streptococcus gallolyticus subsp. pasteurianus infection. A 63-year-old man was admitted to our hospital with epigastric pain and vomiting. He had moderate tenderness and a full sensation in the epigastrium. Abdominal imaging revealed multiple stones in the gallbladder. After admission, he had a high fever that did not improve with antibiotics. Percutaneous transhepatic gallbladder drainage was performed. The patient underwent open cholecystectomy. During surgery, several small stones in the gallbladder and an abscess were observed at the gallbladder base. Streptococcus gallolyticus subsp. pasteurianus was detected by bacterial culture of the bile juice. The gallstones were bilirubin calcium stones. The endoscopic study showed three adenomas in the colon, but the histopathological examination demonstrated no malignant cells. Although infection by this bacterium may not be rare, this is the first reported case in Japan of acute calculous cholecystitis caused by Streptococcus gallolyticus subsp. pasteurianus infection

    Abstract Background Adenosine-to-inosine (A-to-I) RNA editing is catalyzed by adenosine deaminases acting on RNA (ADAR) enzymes. Recent evidence suggests that RNA editing of antizyme inhibitor 1 (AZIN1) RNA is emerging as a key epigenetic alteration underlying cancer pathogenesis. Methods We evaluated AZIN1 RNA editing levels, and the expression of its regulator, ADAR1, in 280 gastric tissues from 140 patients, using a RNA editing site-specific quantitative polymerase chain reaction assays. We also analyzed the clinical significance of these results as disease biomarkers in gastric cancer (GC) patients. Results Both AZIN1 RNA editing levels and ADAR1 expression were significantly elevated in GC tissues compared with matched normal mucosa (P < 0.0001, 0.0008, respectively); and AZIN1 RNA editing was positively correlated with ADAR1 expression. Elevated expression of ADAR1 significantly correlated with poor overall survival (P = 0.034), while hyper-edited AZIN1 emerged as an independent prognostic factor for OS and disease-free survival in GC patients [odds ratio (OR):1.98, 95% CI 1.17–3.35, P = 0.011, OR: 4.55, 95% CI 2.12–9.78, P = 0.0001, respectively]. Increased AZIN1 RNA editing and ADAR1 over-expression were significantly correlated with key clinicopathological factors, such as advanced T stage, presence of lymph node metastasis, distant metastasis, and higher TNM stages in GC patients. Logistic regression analysis revealed that hyper-editing status of AZIN1 RNA was an independent risk factor for lymph node metastasis in GC patients [hazard ratio (HR):3.03, 95% CI 1.19–7.71, P = 0.02]. Conclusions: AZIN1 RNA editing levels may be an important prognostic biomarker in GC patients, and may serve as a key clinical decision-making tool for determining preoperative treatment strategies in GC patients

    Systemic inflammation arising from complex host-tumour interactions is considered the seventh hallmark of cancer. The aim of this study was to assess the clinical feasibility of our newly developed 'lymphocyte-to-C-reactive protein (CRP) ratio' (LCR) and 'lymphocyte CRP score' (LCS) for predicting short- and long-term outcomes in patients with gastric cancer (GC). In this observational study, we retrospectively analysed pre-operative LCRs and LCSs from 551 GC patients to elucidate these prognostic value for overall survival (OS) and disease free survival (DFS) and to clarify these predictive value for peri-operative risk of surgical site infection (SSI) in GC patients. Reduced pre-operative LCRs significantly correlated with all of the well-established clinicopathological factors for disease development, including advanced T stage, venous and lymphatic vessel invasion, lymph node/hepatic/peritoneal metastasis, distant metastasis, and advanced tumour-node-metastasis stage. In the short-term outcome, low pre-operative LCR was an independent predictive factor for post-operative SSI. In the long-term outcome, low pre-operative LCR was an independent prognostic factor for OS and DFS, and prognostic impact of pre-operative LCR were verified in patients with metastatic and non-metastatic gastric cancer. Furthermore, our developed scoring system using lymphocyte and CRP (Lymphocyte-CRP Score; LCS) could also demonstrate all of clinical significance in GC patients, and both of LCR and LCS were significantly correlated with various representative nutrition markers, including BMI, PNI, and albumin, in GC patients. Pre-operative LCR and LCS are clinically feasible nutrition-inflammation markers in GC patients. Assessment of lymphocytes and CRP could aid physicians in determining surgical risk and oncological risk, thus facilitating appropriate peri-operative and post-operative management of patients with GC

    Close relationship between immunological/inflammatory markers and myopenia and myosteatosis in patients With colorectal cancer: A Propensity score matching analysis

    The systemic inflammatory response (SIR) via host-tumor interactions has been termed the seventh hallmark of cancer, and several studies demonstrated that SIR might be a pivotal mediator for progression of cancer cachexia. The objective of this study was to clarify the correlation between sarcopenia and SIR in patients with colorectal cancer (CRC). A total of 308 patients with CRC were enrolled in this study. Preoperative psoas muscle mass index and intramuscular adipose tissue content were evaluated using preoperative computed tomographic images, and the correlation between body composition status and several SIR markers, including C-reactive protein (CRP), serum albumin level, neutrophil-lymphocyte ratio, platelet-lymphocyte ratio, and systemic immune-inflammation index (SII) was assessed using statistical methods. Whereas preoperative myosteatosis was not correlated with clinicopathological factors except for aging and the presence of lymphovascular invasion, preoperative myopenia was significantly associated with well-established clinicopathological factors. Furthermore, the presence of myopenia was significantly correlated with elevated CRP, SII, and neutrophil-platelet score, and decreased lymphocyte-monocyte ratio, prognostic nutrition index, and serum albumin level. Logistic regression analysis revealed that an elevated CRP concentration was an independent risk factor for the presence of preoperative myopenia (odds ratio [OR] 2.49, 95% CI: 1.31-4.72; P = .005). Furthermore, these findings were validated using propensity score matching analysis (OR 2.35, 95% CI: 1.17-4.75; P = .017). Quantification of preoperative CRP could identify patients at high risk for development of myopenia who will likely require individualized treatment plans, including postoperative nutrition intervention, rehabilitation, and oncological follow-up in patients with CRC.
