Association of the miR-146aC>G, miR-149T>C, and miR-196a2T>C polymorphisms with gastric cancer risk and survival in the Greek population.

MicroRNAs (miRNAs) play an important role in regulating gene expression at the post-transcriptional level and are involved in numerous physiological processes. Accumulating evidence suggests that single-nucleotide polymorphisms (SNPs) in human miRNA genes may affect miRNA biogenesis pathway and influence the susceptibility to several diseases such as cancer. The aim of the study was to investigated whether three common miRNA polymorphisms [miR-146a C>G (rs2910164), miR-149 T>C (rs2292832), and miR-196a2 T>C (rs11614913)] are associated with the susceptibility and prognosis of gastric cancer (GC) in the Greek population. The three mRNA SNPs were identified in a case-control study (163 patients; 480 controls) by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis. We found that the risk for GC was significantly higher for the carriers of miR-149 rs2292832CC (p = 0.009) and miR-196a2 rs11614913CC (p < 0.0001) genotypes, as well as for the carriers of the rs2910164/rs2292832/rs11614913 CCC and GTC haplotype (p < 0.0001 and p = 0.03, respectively). The rs2910164/rs2292832/rs11614913 CTT and CCT haplotypes seems to have a protective role against GC (p = 0.002 and p = 0.001, respectively). Our data demonstrate that specific miRNA SNPs are associated with GC susceptibility in the Greek population.

Vacuum-assisted therapy accelerates wound healing in necrotizing soft tissue infections: our experience in two intravenous drug abuse patients.

Negative pressure wound therapy using vacuum-assisted closure (VAC) devices is currently a well established technique for managing complicated wounds. Such wounds occur after aggressive surgical debridement for necrotizing soft tissue infections (NSTI). In this report we present our experience in two intravenous drug abusers managed with VAC for NSTIs. The patients were 25 and 34 years old, HCV positive and presented with oedema of the upper femoral compartments and concomitant severe sepsis. Ultrasonography and computed tomography revealed severe cellulitis, fluid collection and necrosis of the affected fasciae and muscles. After emergent and subsequent aggressive surgical debridement during the first 48h, the VAC device was applied. Both patients had an uncomplicated postoperative course and a fast recovery from their multiorgan dysfunction. Suture closure of the wounds was achieved at the 25th and 38th postoperative days respectively and patients were discharged without any motor deficit. Negative pressure wound therapy is a modern therapeutic modality for treating complicated infected wounds. Moreover, it accelerates wound healing and primary closure, facilitating patient ambulation and recovery. A dedicated medical and nursing team is an important prerequisite for a successful outcome.

Multiple synchronous primary neoplasms of the breast, colon and rectum after surgery for endometrial cancer: A case report.

INTRODUCTION: Endometrial cancer survivors exhibit an increased incidence of subsequent neoplasms. PRESENTATION OF CASE: We present a patient with a history of endometrial cancer who, 3 years after surgery and radiotherapy, developed synchronous neoplasms of the breast, colon and rectum. The patient underwent abdominoperineal resection, a limited right colectomy, and excision of the breast tumour and axillary lymph node dissection. 18 months after surgery, there has been no disease recurrence. DISCUSSION: Multiple primary malignancies represent 16% of new cancer diagnoses. Research on subsequent malignancies after endometrial cancer has shown an increase in risk in colorectal, urinary bladder, lung and breast primaries. CONCLUSION: This case report illustrates the need for physicians to be aware of and counsel patients on the risk of subsequent cancers on endometrial cancer survivors.
