Sonographic Evaluation of Colonic Carcinoma in Comparison to Colonoscopy.

Colon cancer is one of the main causes of cancer death. Diagnosis requires the examination of the entire large bowel by means of radiological or endoscopic techniques. Though there is not a remarkable advancement in gastrointestinal (GI) tract evaluations, the modern radiological imaging methods emphasize the importance of ultrasonography (US) evaluations and stand US out as the scanning method in malignancies of the GI tract. The objective of this study is to investigate the role of ultrasonography in the diagnosis of cancers of the colon & it's accuracy in comparison to colonoscopy. This cross sectional analytical study included a total of 62 patients, including 38(61.29%) male and 24(38.71%) female patients who came at Mymensingh Medical College Hospital & Popular Diagnostic Center, Mymensingh from January 2013 to November 2015 & whose ultrasonography and endoscopic examinations were planned with suspicion of colon cancer. Considering the colonoscopic biopsy as a gold standard, the sensibility, specificity, positive predictive value (PPV) and negative predictive value (NPV) of the ultrasonography were evaluated manually. All patients underwent ultrasonography and colonoscopy and results were compared with histopathologic diagnosis. Malignancy was histopathologically identified in 37(59.68%) patients. The sensitivity of ultrasound to identify colon cancer was 86.48%, its specificity was 84%, positive predictive value and negative predictive value was 88.89% & 80.77% respectively. The sensitivity of endoscopic intervention was 100%, its specificity was 96% and positive predictive value was 93.7%. Likewise, a series of analytical and clinical parameters were evaluated, in an attempt to establish associated factors of a colon cancer by means of the statistical package SPSS 13.0 for Windows. Therefore, we believe that abdominal ultrasonography which is non-invasive, easily accessible, cost-efficient method may detect a colonic mass or wall thickening consistent with a colonic carcinoma with a high degree of accuracy.

Comparison between Angiographic Findings of Coronary Artery Disease in STEMI and NSTEMI Patients of Bangladesh.

Coronary Angiogram (CAG) has been used to detect coronary artery disease in myocardial infarction (both STEMI and NSTEMI) patients. The purpose of this study was to compare the degree of coronary artery disease among STEMI and NSTEMI patients. Among acute coronary syndrome in NSTEMI we found more widespread coronary artery disease other than STEMI. Lack of documentations encouraged us to perform this study in our center. In this retrospective observational study we summarized all myocardial infarction (MI) patients who underwent coronary angiography (CAG) from August 2013 to August 2014 at Enam Medical College Hospital, Dhaka, Bangladesh and data of degree of coronary artery disease were recorded. Data of 100 consecutive MI patients who underwent CAG during that period were recorded. Among them 50 patients having STEMI as Group I (male 45, female 5) & other 50 patients sustained NSTEMI as Group II (male 38, female 12). Among NSTEMI patient group 80% were having multi-vessel disease and in STEMI patient group 80% having single vessel disease and remaining having multi-vessel disease. The degree of coronary artery disease is extensive in NSTEMI patients than in STEMI group. Coronary angiogram can visualize the degree of coronary artery involvement and is a useful screening modality to compare disease extent in MI patients.
