#1
REVIEW
Ju Yong Cheong, Anil Keshava
Traumatic colorectal injuries are common during times of military conflict, and major improvements in their care have arisen in such periods. Since World War II, many classification systems for colorectal trauma have been proposed, including (i) Flint Grading System; (ii) Penetrating Abdominal Trauma Index; (iii) Colonic/Rectal Injury Scale; and (iv) destructive/non-destructive colonic injuries. The primary goal of these classifications was to aid surgical management and, more particularly, to determine whether a primary repair or faecal diversion should be performed...

OBJECTIVE: To evaluate the long-term prognostic factor of preoperative anemia in colorectal cancer patients. BACKGROUND: Anemia is frequently observed in colorectal cancer patients, with a case incidence of 30 to 67 percent. Besides an indicator of tumor-induced blood loss and inflammation, anemia in cancer is also suggested to be a cause of inferior outcome, possibly via worsening of tumor hypoxia. As surgery is likely to enhance anemia, the long-term prognostic value of preoperative anemia seems most interesting...

Intestinal neuronal dysplasia type B is a controversial entity expressed by complex changes in the enteric nervous system. Diagnosis depends on rectal biopsy histopathology and diagnostic criteria, both qualitative and quantitative, have changed over time, hindering the diagnostic practice. We analyzed the morphological criteria for the histological diagnosis of intestinal neuronal dysplasia type B in a series of patients with intestinal neuronal dysplasia type B according to the 1990 Frankfurt Consensus criteria and verified the applicability of the numerical criteria proposed by Meier-Ruge et al in 2004 and 2006...

PURPOSE: Alcohol consumption has been purported to influence many diseases. MicroRNAs (miRNAs) may be influenced by compounds found in alcohol. In this investigation, we test the hypothesis that total alcohol, beer, wine, and hard liquor influence miRNA expression. METHODS: We studied 1447 colorectal (CR) cancer cases with normal CR mucosa and carcinoma miRNA expression data along with alcohol consumption data. We analyzed long-term and long-term and current (LTC) alcohol use for beer, liquor, and wine with miRNA expression between paired carcinoma and normal colon and rectal tissues, adjusting for multiple comparisons using the positive false discovery rate q-value...

BACKGROUND/OBJECTIVE: Positive carcinoembryonic antigen (CEA) messenger RNA (mRNA) in peritoneal lavage is associated with poor prognosis in patients with colon cancer. However, there are no reports about rectal cancer. Therefore we aimed to evaluate the frequency of positive CEA mRNA in peritoneal lavage and the significance of CEA mRNA in patients with low rectal cancer. METHODS: A total of 55 patients with low rectal cancer who received curative surgical resection were enrolled...

REVIEW
T Campion, S Cross
Buttock stab wounds are a surprisingly common and increasing source of presentations to emergency departments. These injuries can have a significant impact on quality of life, and there are a number of often subtle, but significant, injuries that the radiologist must be alert to when interpreting computed tomography examinations in these patients. In this review, we will examine briefly the sociological reasons for the increase in these injuries, discuss appropriate imaging techniques, and provide imaging examples of the clinically important injuries that may be encountered in this region...

PURPOSE: Post-transrectal ultrasound-guided prostate biopsy sepsis is an increasing problem in this era of rising antibiotic resistance. Ertapenem prophylaxis has proven very effective at our institution for reducing this, however has raised local and regional antimicrobial stewardship concerns. This study investigated the possible selective effect of single dose ertapenem prophylaxis on fecal colonization with carbapenem-resistant Enterobacteriaceae. MATERIALS AND METHODS: Patients had a rectal swab taken prior to receiving pre-biopsy ertapenem prophylaxis...

AIM: To evaluate the diagnostic performance of contrast enemas (CEs) for the diagnosis of Hirschsprung's disease (HD). METHODS AND MATERIALS: CE studies performed as part of an HD workup in patients 1-18 years of age over a 10-year period were identified. All abnormal CE studies and an equal number of age-matched controls were included in the final study group. Two radiologists independently and blindly reviewed all CE studies for quality (scale of 0-3) and the presence of large colon calibre, colon redundancy, transition zone, rectosigmoid ratio, and abnormal contractions...

Lower gastrointestinal (GI) neuroendocrine neoplasms (NENs) of the colon and rectum are uncommon and not traditionally associated with hereditary GI cancer syndromes. However, with widespread implementation of colorectal cancer screening programs, lower GI NENs are being identified with increasing frequency. We report the first case series of six patients with lower GI NENs who were diagnosed with hereditary GI cancer syndromes by germline testing. Two patients presented with poorly differentiated rectal neuroendocrine carcinoma (NECs) with colonic polyposis and were found to have Familial Adenomatous Polyposis and MYH-Associated Polyposis, respectively...

BACKGROUND: Carbapenem-resistant Klebsiella pneumoniae (CRKP) spread and infections in patients with haematological malignancies are a serious concern especially in endemic areas. Treatment failures and delay in appropriate therapy for CRKP infections are frequent and the mortality rate associated with CRKP bacteremia in neutropenic haematological patients is reported about 60%. METHODS: Haematological patients harboring CRKP hospitalized between February 2012 and May 2013 in an Italian Teaching hospital were examined...

With the universal adoption of antibiotic prophylaxis prior to prostate biopsy, the current risk of post-biopsy infection (including sepsis) is <2%. Preoperative prophylactic antibiotic regimens can vary, and although fluoroquinolones have emerged as the standard of care, there is no universally agreed upon preoperative antibiotic regimen. Recently, an increase in the proportion of postoperative infections caused by fluoroquinolone-resistant Escherichia coli (as well as other Enterobacteriaceae) has led to the exploration of simple, practical, and cost-effective methods to minimize this postoperative infection risk...

BACKGROUND: In the management of metastatic colorectal cancer (mCRC), KRAS, NRAS and BRAF mutational status individualizes therapeutic options and identify a cohort of patients (pts) with an aggressive clinical course. We hypothesized that relapsed and refractory mCRC pts develop unique mutational signatures that may guide therapy, predict for a response and highlight key signaling pathways important for clinical decision making. METHODS: Relapsed and refractory mCRC pts (N=32) were molecularly profiled utilizing commercially available next generation sequencing (NGS) platforms...

Advances in the field of metagenomics using culture-independent methods of microbial identification have allowed characterization of rich and diverse communities of bacteria in the lungs of healthy humans, mice, dogs, sheep and pigs. These data challenge the long held belief that the lungs are sterile and microbial colonization is synonymous with pathology. Studies in humans and animals demonstrate differences in the composition of airway microbiota in health versus disease suggesting respiratory dysbiosis occurs...

OBJECTIVES: Randomized controlled trials, especially the Early Palliative Care Study (Temel et al., 2010), have shown that early outpatient palliative cancer care can improve quality of life for patients with advanced cancer or serious symptoms. However, fear and misconceptions drive avoidance of palliative care. Drawing from an empowerment perspective, we examined whether educating patients about evidence from the Early Palliative Care Study would increase preferences for palliative care...

Endometriosis is a common gynecological condition wherein there is an ectopic implantation of the uterine endometrial tissue. While several diagnostic modalities are described for the condition, laparoscopy remains the gold standard. There is still an undiscovered area to diagnose colonic endometriosis at an earlier stage. We present a case report of a reproductive age woman with cyclical rectal bleeding diagnosed with colonic endometriosis with colonoscopy and biopsy using saline injection lift and sampling technique...

SMAD4 is an essential mediator in the transforming growth factor-β pathway. Sporadic mutations of SMAD4 are present in 2.1-20.0% of colorectal cancers (CRCs) but data are limited. In this study, we aimed to evaluate clinicopathologic characteristics, prognosis, and clinical outcome associated with this mutation in CRC cases. Data for patients with metastatic or unresectable CRC who underwent genotyping for SMAD4 mutation and received treatment at The University of Texas MD Anderson Cancer Center from 2000 to 2014 were reviewed...

BACKGROUND: Colon cancer is currently staged with CT. However, MRI is superior in the detection of colorectal liver metastasis, and MRI is standard in local staging of rectal cancer. Optimal (local) staging of colon cancer could become crucial in selecting patients for neoadjuvant treatment in the near future (Fluoropyrimidine Oxaliplatin and Targeted Receptor Preoperative Therapy trial). OBJECTIVE: The purpose of this study was to evaluate the diagnostic performance of MRI for local staging of colon cancer...
