BACKGROUND: Although intravenous (i.v.) lidocaine is used as a perioperative analgesic in abdominal surgery, evidence of efficacy is limited. The infusion dose and duration remain unclear. This study aimed to investigate the effect of a longer low-dose 48-hour infusion regimen on these outcomes. METHODS: Fifty-eight adults undergoing elective open colorectal surgery were randomized into the lidocaine group (1.5 mg/kg bolus followed by 1 mg/kg/h infusion for 48 hours) and control group. After surgery, patients were given a fentanyl patient-controlled analgesia machine and time to first bowel movement (primary outcome) and flatus were recorded. Postoperative pain scores and fentanyl consumption were assessed for 72 hours. RESULTS: There was no significant difference in time to first bowel movement (80.1 ± 42.2 vs. 82.5 ± 40.4 hours; P = 0.830), time to first flatus (64.7 ± 38.5 vs. 70.0 ± 31.2 hours; P = 0.568), length of hospital stay (9 [8–13] vs. 11 [9–14) days; P = 0.531], nor postoperative pain scores in the lidocaine vs. control groups. Cumulative opioid consumption was significantly lower in the lidocaine vs. the control group from 24 hours onwards. At 72 hours, cumulative opioid consumption (µg fentanyl) in the lidocaine group (1,570 [825–3,587]) was over 40% lower than in the placebo group (2,730 [1,778–5,327]; P = 0.039). CONCLUSIONS: A 48-hour low-dose i.v. lidocaine infusion does not significantly speed the return of bowel function in patients undergoing elective open colorectal surgery. It was associated with reduced postoperative opioid consumption, but not with earlier hospital discharge, or lower pain scores.

Epigenetics is defined as an inheritable effect that influences gene activity, but does not involve a change in DNA sequence. Epigenetic gene regulation has an essential role in determining individual gene function and activity in each specific cell type. Epigenetics includes four predominant mechanisms: DNA methylation, histone modification, nucleosome positioning and microRNA (miRNA). These mechanisms influence gene expression, cell differentiation, proliferation, DNA repair and replication. Epigenetic modifications are far more sensitive to environmental stimuli than DNA sequence alterations. Candidate gene approaches have identified a small set of genes that undergo epigenetic changes, such as aberrant DNA demethylation, histone modification, as well as regulation by miRNA in rheumatic diseases. It is well known that T cells from patients with SLE or RA, as well as synovial fibroblasts from individuals with RA, have sequences undergoing DNA hypomethylation and/or histone modifications. In addition, miRNA regulates the gene expression by pairing with its target mRNAs and is often deregulated in systemic rheumatic diseases. High-throughput approaches are necessary for screening the epigenetic alterations, and it is essential to screen the specific tissue and cell types that are relevant to the disease pathogenesis. Identification of cell-specific targets of the epigenetic deregulation in rheumatic disorders will provide clinical markers for the diagnosis, disease progression and response to therapy. Our understanding of epigenetics is in its infancy. New generation of pharmaceuticals, which manipulate the epigenome to the switch targeted genes on or off are under investigation. The new field of repairing or optimizing the epigenome through epigenetic modifier and/or diet is wide open.

OBJECTIVE: Axial spondyloarthritis (axSpA) is often accompanied by cardiac manifestations, such as valvular heart disease. In this prospective cohort study, we evaluated the incidence of cardiac abnormalities in Korean axSpA patients by echocardiography. METHODS: AxSpA patients were prospectively recruited from a single tertiary hospital. Baseline demographic, clinical, radiographic, and echocardiographic data were collected at the time of enrollment. Echocardiography evaluations were performed with a focus on valvular heart disease and systolic and diastolic function. Logistic regression analyses were used to identify factors associated with diastolic dysfunction in axSpA. RESULTS: A total of 357 axSpA patients were included in the analyses, of whom 78 (21.8%) exhibited diastolic dysfunction, with no reports of systolic dysfunction. Thirteen patients (3.6%) had valvular heart disease, and aortic valve regurgitation (n=5) and mitral valve regurgitation (n=6) were most common. Multivariable logistic regression analyses indicated that older age and higher body mass index (BMI) were positively associated with diastolic dysfunction, whereas human leukocyte antigen (HLA)-B27 positivity was negatively associated with diastolic dysfunction. CONCLUSION Valvular heart disease is infrequent in Korean axSpA patients. However, diastolic dysfunction is common in axSpA patients, and is significantly associated with older age, higher BMI, and HLA-B27.

Axial spondyloarthritis and sarcoidosis are both inflammatory multi-system diseases. Having different pathophysiologies, they develop different typical lesions. The co-occurrence of both diseases is rare and nature of the association between the entities is unknown.

Pulmonary hypertension (PH) is a rare manifestation in patients with primary Sjogren's syndrome (pSS) and it can occur with or without interstitial lung disease (ILD). Patients with PH and ILD who show signs of exacerbation of dyspnea are commonly assessed for pure PH aggravation, ILD progression or pulmonary infection. However, the presence of congenital cardiac anomalies, such as partial anomalous pulmonary vein return (PAPVR), can also be a cause of dyspnea exacerbation. PAPVR is a rare congenital anomaly that involves drainage of 1 to 3 pulmonary veins into the right-sided heart circulation, resulting in a partial left-to-right shunt. Here we present a case of PAPVR as the cause of PH aggravation in a patient with pSS with accompanying PH.

The most common metastatic sites of gastric cancer are liver, lung, bone and adrenal gland. However, skin metastases from gastric cancer are relatively rare. We herein report a case of advanced gastric cancer with perianal skin metastasis in a 70-year-old male. On admission, patient presented with epigastric pain. Endoscopy and abdominal CT scan demonstrated the stage IV gastric cancer. He had one painless nodule on perianal skin area, biopsy of that lesion showed a feature of poorly differentiated adenocarcinoma clinically from the stomach. We suspected that the perianal lesion was originated from gastric cancer.

Hyperplastic polyps occur either sporadically or as a symptom of polyposis syndrome. When individuals exceed 50 polyps, they are diagnosed with hyperplasic polyposis. Moreover, since such cases are even more sporadic than hyperplastic polyps, the course toward this occurrence has not been properly evaluated. A change to malignancy in hyperplastic polyps is rare; however, when multiple lesions are present, the tendency increases. Colorectal polyposis syndromes with gastric polyps include familial adenomatous polyposis, Gardners syndrome, Peutz-Jeghers syndrome, juvenile polyposis and others with a non-genetic origin. Three cases of multiple colorectal hyperplastic polyposis with gastric hyperplastic polyposis have been reported worldwide; however, a case associated with multiple colonic adenomas has not yet been reported. This study reviews the existing literature and reports our recent experience of a case, in which a 53 year-old man with colorectal and gastric hyperplastic polyposis with associated multiple colonic adenomas.

BACKGROUND: Breast carcinoma amplified sequence 1 (BCAS1), located in 20q13, is amplified and overexpressed in breast cancers. Even though BCAS1 is expected to be an oncogene candidate, its contribution to tumorigenesis and copy number status in other malignancies is not reported. To elucidate the role of BCAS1 in squamous cell carcinomas, we investigated the copy number status and expression level of BCAS1 in several squamous cell carcinoma cell lines, normal keratinocytes and primary tumors. METHODS: We quantitated BCAS1 gene by real-time polymerase chain reaction (PCR). Expression level of BCAS1 was measured by real-time reverse transcription-PCR and immunoblot. RESULTS: Seven (88%) of 8 squamous cell carcinoma cell lines showed copy number gain of BCAS1 with various degrees. BCAS1 gene in primary tumors (73%) also showed copy number gain. However, expression level did not show a linear correlation with copy number changes. CONCLUSIONS: We identified copy number gain of BCAS1 in squamous cell carcinomas. Due to lack of linear correlation between copy numbers of BCAS1 and its expression level, we could not confirm that the overexpression of BCAS1 is a common finding in squamous cell carcinoma cell lines. However, this study shows that the copy number gain of BCAS1 is a common finding in squamous cell carcinomas.
