Based upon our results, there is a different biological profile between right- and left-sided colonic tumors.

From the results of this study, it appears that ilioinguinal nerve entrapment and/or mesh fixation on the periostium of the pubic tubercle are the causes of late-onset severe chronic pain after inguinal mesh hernioplasty. Mesh removal, along with the stuck ilioinguinal nerve and staple detachment from the periostium, are the gold-standard techniques if conservative measures fail to reduce pain.

Combined administration of 4 per cent icodextrin and dimetindene maleate may be used safely and efficaciously to prevent surgically induced adhesions.

Colorectal cancer surgery in the elderly is a challenging clinical scenario. Treatment decision adjusted to each individual case is the ideal practice in order to maintain an acceptable balance between curative cancer resections and palliative procedures.

Introduction. We report the case of an appendiceal carcinoid tumor within an Amyand's hernia, presenting as an incarcerated right inguinal hernia. Presentation of Case. A 52-year-old male presented in the emergency department due to a persistent right inguinal pain. Clinical examination revealed a tender right groin mass. Laboratory tests revealed leukocytosis and an increased serum CRP. Under the diagnosis of an incarcerated right inguinal hernia, an emergency operation was taken. Intraoperatively, an inflamed appendix and a part of the cecum were found in the hernia sac. The operation was completed with an appendectomy and a modified Bassini hernia repair. Histological examination revealed a carcinoid tumor, resulting in the performance of a right hemicolectomy. Discussion. Amyand's hernia is estimated to account for 0.4% to 0.6% of all inguinal hernias. Coexistence of an Amyand's hernia and a neoplasia is quite rare. Carcinoids are the most frequent tumors found in the appendix, with the size of the primary tumor to be considered the most important prognostic factor and the basis upon which the operative plan is decided. Conclusion. A malignancy of the appendix should always be in the differential diagnosis of a right inguinal mass, in order to provide optimum surgical treatment.

A rare case of multiple small bowel ruptures due to ischemic enteritis (ISE) is reported. The patient was admitted to the hospital with acute abdominal pain followed by bloody diarrhoeas. Preoperative colonoscopic findings were similar to those presented in Crohn's disease. Intraoperatively, ischemic lesions and multiple ruptures were localized at the jejunum and the proximal ileum. Histopathological examination of the resected bowel segment established the diagnosis of ISE. Although ISE is not common, concurred multiple ruptures of the small bowel is a rare but actual complication.

OBJECTIVES Thoracic aortic aneurysm (TAA) is characterized by the dilation of the aorta and is associated with poor prognosis if not diagnosed and treated early. In this context, the identification of biomarkers regarding the TAA diagnosis, monitoring and prognosis is crucial. The purpose of the current study was to investigate the differential gene expression profile of the cadherin 5 (CDH5 or VE-Cadherin) gene network in patients with TAA, to propose novel biomarkers. METHODS In silico techniques were used to construct the interactome of the CDH5 network, identify the differentially expressed genes (DEGs) in TAA as compared to healthy controls, and uncover the related molecular functions and the regulating miRNAs. RESULTS Transcriptomic data of one microarray dataset were included, incorporating 43 TAA and 43 control samples. Eight DEGs were identified; 7 were up-regulated and 1 was down-regulated. A molecular signature of 8 genes (CDH5; Calcitonin Receptor-Like Receptor–CALCRL; Activin A Receptor-Like Type 1–ACVRL1, Tryptophanyl-TRNA Synthetase 1–WARS; Junction Plakoglobin–JUP, Protein Tyrosine Phosphatase Receptor Type J–PTPRJ, Purinergic Receptor P2X 4–P2RX4, Kinase Insert Domain Receptor–KDR) were identified as biomarkers associated with TAA. PTPRJ was associated with excellent discrimination and calibration in predicting TAA presentation. Positive correlations were reported regarding the expression of CDH5-CALCRL, CDH5-ACVRL1, CDH5-WARS and CDH5-PTPRJ. Finally, gene set enrichment analysis indicated the molecular functions and miRNA families (hsa-miR-296-5p, hsa-miR-6836-5p, hsa-miR-6132, hsa-miR-27a-5p and hsa-miR-6773-5p) relevant to the 8 biomarkers. CONCLUSIONS These outcomes propose an 8-gene molecular panel associated with TAA.
