Colorectal carcinomas occur primarily in elderly people and are rare in children. Unlike adult colorectal carcinomas, the overall prognosis is very poor because of the usual delay in diagnosis and advanced stages at presentation or initial diagnosis, and a high incidence of aggressive tumor pathology such as mucinous adenocarcinoma. Colon cancer should not be excluded in children only based on age or barium enema results. Therefore, colonoscopy should be performed in pediatric patients with unexplained rectal bleeding and abdominal pain. We report a rare case of a child with a mucinous adenocarcinoma of the sigmoid colon in a 12-year-old boy, who presented with an abdominal mass and abdominal pain and review the medical literature.

A 7-year-old castrated male Cocker spaniel dog was referred to Gyeongsang National University Veterinary Medical Teaching Hospital with a severe abdominal distension. A huge, inhomogeneous fat opacity mass was identified on the abdomen radiographic survey. From the abdominal ultrasonographic examination, the mass was found to have irregular marginated hyperechoic capsule with cellular hypoechoic fluids inside. On the computed tomography, an encapsulated inhomogeneous mass was identified with fat attenuation peripheral and soft tissue attenuation inside. The origin of the mass was confirmed as falciform fat by surgical excision. The resected mass appeared to be a firm reddish-brown color with a smooth surface. The histopathological appearance was a well-differentiated liporsarcoma. The patient has no recurrent signs 1 month after surgery.

Newborn gastrointestinal tract emergency diseases include various disorders that occur anywhere along the digestive tract. Most of them are congenital malformations, not acquired diseases. Many of them cannot be confirmed on prenatal examination, and consequently, postnatal evaluation is required. Unlike adults, in newborn babies, detailed evaluations with computed tomography (CT) and magnetic resonance imaging (MRI) are often limited, so making the diagnosis based on early abdominal radiography is most important. Therefore, it is necessary to be familiar with the radiologic findings that may be seen on imaging studies. In addition, it is important to understand abdominal ultrasound and fluoroscopy findings, which can be used in addition to simple radiography and indications that can be used for further diagnosis and appropriate treatment. Therefore, this study describes and organizes the various imaging findings that may occur in neonatal gastrointestinal emergencies.

An 8-year-old castrated male domestic shorthair cat (Case 1) and 3-year-old castrated male Siamese cat (Case 2) was presented with acute paresis of the hindlimbs, constant open-mouth breathing, and hemoptysis. Heart murmur (Case 1) and gallop sound (Case 2) was ausculated on the left heart base. Radiographs revealed alveolar infiltration of the caudodorsal lung lobes with aerophagea in Case 1 and prominent cardiomegaly in Case 2. Marked concentric hypertrophy of the ventricular septum and free wall, and left atrial enlargement was detected through echocardiography in both cats. Based on the examinations including echocardiography, those cats were diagnosed as hypertropic cardiomyopathy. Abdominal ultrasound revealed echogenic material in the aortic trifurcation region, aortic thromboembolism (ATE). Although prognosis of those animals was guarded, interventional therapeutic approach through direct endovascular thrombolytic therapy was attempted. ATE was visualized through angiography; however dissolving the embolus using interventional thrombolytic approach was not successful due to the extensive thrombus.

An 1-year-old intact male Jindo dog weighing 20 kg was referred with 7-day history of vomiting, anorexia, and lethargy. The dog was diagnosed with chronic kidney disease (CKD) based on clinical signs, urinalysis, serum biochemistry, radiology and abdominal ultrasonography. Ten days of conservative therapy was given, but there were no signs of improvement. The patient was euthanized and necropsy was conducted. Renal histopathology was consistent with juvenile nephropathy and this is the first report of juvenile nephropathy in a Jindo dog.

The incidence of gallbladder polyps are increasing due to the extended use of ultrasonography. Although there are various reports on the risk of gallbladder polyps, there are few studies of the relationships among the presence of metabolic syndrome including serum biochemistry, lifestyle and the development of gallbladder polyps. The aim of this study was to determine association of the presence of metabolic syndrome, including serum biochemistry, with the development of gallbladder polyps in the Korean population. Among the health examination examinees, 596 people, who underwent abdominal ultrasonography from January, 2013 to December 2013, were included in this study. Physical measurements also taken, such as height, weight, blood pressure, waist measurement, and BMI. The general characteristics including age, sex, smoking, and drinking as the related factors were checked. At the same time, various blood tests were performed and the fasting blood sugar was analyzed through blood-gathering to determine the presence of metabolic syndrome. Regarding the factors associated with gallbladder polyps, the results showed that being male, smoking, non-drinking were significantly high. In addition, testing positive for HBsAg and an increasing BMI was apparently higher the group with metabolic syndrome than the non-metabolic syndrome group. The highest predictive factors for gallbladder polyps was being male (1.8 times), followed by metabolic syndrome (2.3 times) and testing positive for HBsAg (2.6 times).

Tuberculous peritonitis is a rare cause of intra-abdominal infection. Although sometimes asymptomatic, most of the patients have fever, weight loss, abdominal pain, and edema. The diagnosis of tuberculous peritonitis is difficult and sometimes delayed because of confusion of the disease with other illnesses and the non-specificity of signs and symptoms. Tuberculous peritonitis is examined with ultrasonography and computerized tomogram, but confirmed by biopsy or tuberculosis culture. Ascitic fluid is exudates with a lot of lymphocytes and elevated protein. Tuberculous peritonitis is treated successfully with isoniazid, rifampicin for one year, pyrazinamide for first 2 months and streptomycin for first one month. We experienced one case of tuberculous peritonitis with transudate of ascitic fluid, confirmed by biopsy using colonoscopy, and treated successfully.

An eight-year-old intact male Beagle had anorexia, vomiting, depression for two days. The dog had hypoalbuminenia and mild azotemia on hematologic and clinical chemistry examinations. Severe proteinuria was identified on urinalysis. On abdominal ultrasonographs, there were small amount of ascites and bilateral renomegaly with severe hyperechoic renal cortex and hyperechoic medullary rim sign. Renal biopsy and histopathology revealed renal amyloidosis. The quality of life in this dog was satisfactory with aggressive supportive care for three months. Euthanasia was performed due to deteriorated azotemia and nephrotic syndrome.

During the medical ultrasound exercise at school, we randomly select parts of the ultrasound device and areas with the most contact in the abdominal phantom to detect bacteria that are above the probe and determine the number of pathogens. I want to find out. The experimental method was rubbed 20 times with the sterilized cotton swab for sterilization and then smeared on Lysogeny broth (LB) agar, put into the incubator and incubated for 48 hours, and the colony forming unit (CFU) count was measured. The bacterial distribution of probe handle and abdominal phantom was evaluated by evaluation. As a result, the CFU value is the lens was $3.0{\pm}0.87$, print button was $5.5{\pm}1.06$, freeze button was $8.0{\pm}4.95$, phantom was $20.0{\pm}2.78$, line was $23.5{\pm}2.50$, and probe handle was measured as $35.3{\pm}10.75$. In this study, it is expected that attention to infection control of equipment during practice during medical ultrasound practice can be highlighted and further contributed to the reduction of bacterial infection rate of ultrasound devices.

A 10-year-old spayed female Pekinese dog was referred to veterinary medical teaching hospital of Chonbuk National University with signs of dysuria, abdominal distension, and hematuria. Abdominal radiography revealed a large oval soft tissue mass in cranial abdomen, which was a fluid filled cyst containing a round mass by ultrasonography. Exploratory laparatomy found a 4 cm cyst containing reddish brown fluid and a 1.5 cm small round mass attached to the wall. Cytological impression of the imprint smears of the resected mass were highly malignant adenocarcinoma, which was confirmed by histopathology of the mass and the cyst. After the surgery the patient recovered uneventfully and discharged. The tumor recurred about one year after surgery, and second surgery performed at the owner's request. However the tumor recurred in two months with metastatic disease in the lung and the dog survived three more months after surgery.
