actinomycosis is a rare and chronic infectious disease caused by a non-spore gram- positive, anaerobic bacterium that rarely infects the colon, in particular the left colon. a 53-year-old woman was referred to us due to chronic abdominal pain, bloating, a few episodes of bloody-mucous rectal discharge, and change of bowel habits. her medical history and physical examination were unremarkable. ...
The gastrointestinal tract normally functions to move ingested food, in an organized fashion, from the oropharynx, through the stomach, small intestine and colon and into the rectum, from which it can be expelled. The primary function of the colon is to absorb water and electrolytes from the chyme delivered and, thus, determine the frequency, consistency, and volume of stools eliminated. The co...
Background: This study presents patient specific and organ dose estimation in computed tomography (CT) imaging of thorax directly from patient CT image using Monte Carlo simulation. Patient's CT image is considered as the patient specific phantom and the best representative of patient physical index in order to calculate specific organ dose. Materials and Methods: EGSnrc /BEAMnr...
Introduction: Mayer–Rokitansky–Küster–Hauser (MRKH) syndrome is a rare disorder in women which identified as agenesis of vagina and hypoplasia or agenesis of uterine. Case presentation: in this study, two female cases (17, and 19 years old) diagnosed with MRKH (first one type 2, and second one type 1) are described. Both patients were presented with amenorrhea, and absence of vagina orifice. On...

The diagnostic and screening colonoscopy for is different for colon diseases. In order for colonoscopy, colon cleansing is required to prepare a detailed view into the intestinal lumen. Aim: This is a case report study of a patient with multiple pyogenic liver abscesse...
Radiation-associated colon cancer is a rare clinical entity. We herein describe the case of a patient with radiation-associated colon cancer who had undergone low anterior resection for rectal cancer following preoperative radiotherapy. Certain characteristics of radiation-associated colon cancer are highlighted. The patient was a 48-year-old man who had undergone low anterior resection for rec...
Background: Annual patient effective dose equivalent can be considered as a quantitative physical parameter describing the activities performed in each nuclear medicine department. Annual staff dose equivalent could be also considered as a parameter describing the amount of radiation risk for performing the activities. We calculated the staff to patient dose equivalent ratio to be used as a phy...
The mainstay of pharmacologic therapy in patients with inflammatory myositis is corticosteroid and sometimes immunosuppressive drugs. However, because patients sometimes become refractory to these drugs and since these drugs have potential short and long-term toxicities, an alternate therapy is highly desirable. Therefore, a pilot study was initiated using intravenous gammaglobulin(IV...
iatrogenic perforation of the colon during elective colonoscopy is a serious complication. surgical treatment remains the standard of care. we report a patient with a large colonic perforation that occurred during a screening colonoscopy, successfully repaired with laparoscopic methods. although the safety and efficacy of this approach is not entirely established, laparoscopy can be used to tre...
a man with metastatic carcinoma of the colon had a bone scan which revealed urinary retention in the leftkidney. ten months later, a tc-99m-dtpa renai glomerular study showed the left kidney to have only 8% oftotal renal function. fifteen months after that, (he same kidney demonstrated 9% of total function, while theright kidney had evolving obstruction due to his neoplasm. the case shows that ...
