Ileocolonic mucormycosis in adult immunocompromised patients: A surgeon's perspective

We report three cases of ileocolic mucormycosis in adult immunocompromised patients presenting as acute abdomen. All patients underwent laparotomy but two of them died from multiorgan failure before the diagnoses were confirmed. The diagnosis of gastrointestinal mucormycosis is rarely suspected, and antemortem diagnosis is made in only 25%-50% of cases. These cases illustrate the difficulty encountered by surgeons in managing acute abdomen in neutropenic patients with hematological malignancy. The management of colonic mucormycosis in the published literature is also reviewed. © 2010 Baishideng. All rights reserved.published_or_final_versio

Multimodality minimally invasive autopsy-A feasible and accurate approach to post-mortem examination

Background: Autopsy examination has been the bedrock of western medicine. With the decline in the autopsy rate secondary to the negative psychological impact to the deceased's relatives, the benefits of autopsy have been undermined. Minimally invasive autopsy has been introduced but has not been widely adopted as an alternative to the 'traditional' open approach. This technique not only provides information on the cause of death abut also minimizes the disfigurement induced to the deceased. Our study aims to explore the feasibility and evaluate the accuracy of this technique. Methods: A series of coroner cases ordered for autopsy were examined by a group including an experienced forensic pathologist and two experienced laparoscopic surgeons using thoracoscopic, laparoscopic, endoluminal or endovascular approaches. The procedure was video-recorded and the provisional diagnoses and causes of death were made based on the findings. These findings were subsequently correlated with the full autopsy examination. A few limited clinical post-mortem examinations were also performed with consent from relatives. Results: A total of 22 cases of minimally invasive autopsies were performed from November 2007 to March 2008. The median duration of the procedures was 78.3 ± 20.7 min. Thoracoscopies and laparoscopies were performed in 18 patients while additional arterioscopic examination with endoscope was performed in two patients with suspected aortic diseases. Four consented limited clinical autopsies were also performed: two of them involved thoracoscopic biopsies of lung tissues, one was a para-mortem upper endoscopy for the investigation of pathology of the stomach and the other one was laparoscopy for a patient, who died of unexplained acidosis. Comparison with full autopsies showed that the accuracy of the diagnosis was 94.4%, the sensitivity was 90%, the specificity was 100%, the positive predictive value was 100% and the negative predictive value was 88.9%. Conclusion: Minimally invasive autopsy is a feasible approach, yielding accurate findings when compared with conventional autopsies. The former can be a valuable tool for obtaining more valuable information in situations when the next-of-kin of the deceased does not consent to a conventional autopsy. © 2009 Elsevier Ireland Ltd.

Identification of serum miR-139-3p as a non-invasive biomarker for colorectal cancer

Aberrant levels of circulating microRNAs are potential biomarkers for the early detection of colorectal cancer. The aim of this study was to study miR-139-3p and miR-622 in serum as a non-invasive biomarker for colorectal cancer diagnosis. We applied quantitative polymerase chain reaction to determine the levels of miR-139-3p and miR-622 in 42 pairs of tumor and adjacent non-tumor tissues, and in serum samples of 117 patients and 90 control subjects. Our results showed that miR-139-3p was silenced whereas miR-622 was overexpressed in colorectal cancer. Similarly, serum miR-139-3p level was significantly lower in colorectal cancer patients than in control subjects whereas miR-622 was more frequently detectable in patients. ROC analysis showed that AUC of miR-139-3p was 0.9935, with a sensitivity of 96.6% and specificity of 97.8%. Serum miR-139-3p level showed high sensitivity and specificity for both early and late stage CRCs and proximal and distal CRCs. Detectable serum miR-622 showed a sensitivity of 87.5% and specificity of 63.5% for discriminating CRC patients, but the sensitivity dropped for late stage patients (72.7%). We also included analyses of the blood CEA level for comparing the diagnostic performance of these blood-based biomarkers. The median level in CRC patients (3.6 ng/ml) was significantly higher than that in control (1.8 ng/ml). The AUC value of CEA in diagnosing CRC patients was 0.7515. CEA showed a positive correlation with tumor stage and age of patients and its level was higher in male. Collectively, serum miR-139-3p has strong potential as a promising non-invasive biomarker in colorectal cancer detection.published_or_final_versio
