This study was purposed to make the referenced range of stomach antral contraction strain in 50 dogs using 2-dimensional speckle tracking. In addition, the strain results were compared among body condition scores to reveal the correlations of obesity among the subjects of the study. Finally, the medetomidine group that was comprised of 10 dogs was compared with the normal group to identify the medetomidine pharmacologic effect in the stomach antral contraction. Clinically healthy 50 dogs were recruited for the study. In an ultrasonographic examination, the stomach antrum region was scanned, and at least one cycle of antral contraction was recorded. The peak strain of antral contraction in healthy dogs was 58.2 ± 20.47% (mean ± SD). The obesity group showed a high strain result and there were significant correlations between the body condition score (BCS) 2, BCS 3 groups and BCS 8 group. The medetomidine group revealed a low strain result and was significantly correlated with normal group. Two-dimensional speckle tracking was useful to the evaluation of stomach motility disorders.

Syndrome of inappropriate secretion of antidiuretic hormone (SIADH) may be observed in various types of cancer, but is mainly seen in small-cell carcinoma. It can also be caused by several chemotherapeutic agents. However, it is a very rare phenomenon in esophageal cancer or its treatment. We report here on a case of SIADH related to esophageal cancer treatment. A 55-year-old man received chemoradiotherapy (CRT) for esophageal cancer. After receiving CRT for 5 days, he complained of nausea, dizziness, and general weakness, and his sodium level had dropped to 107 mEq/L. His volume status was clinically euvolemic and there were no edema or pigmentation. After hypertonic saline infusion, the sodium level increased and the symptoms improved. There have been several reports of SIADH associated with malignancies or chemotherapy agents. However, to the best of our knowledge, this is the first Korean case of SIADH associated with esophageal cancer that occurred after cisplatin treatment.

Background: Bone subtraction computed tomography angiography (BSCTA) is a useful alternative technique for improving visualization of vessels surrounded by skull bone.However, no studies have compared computed tomography angiography (CTA) and BSCTA for improving the visibility of canine cerebral blood vessels. Objectives: To evaluate the potential benefit of BSCTA for better delineation of brain arteries of the circle of Willis (CoW) in dogs by comparing BSCTA with non-subtraction computed tomography angiography (NSCTA). Methods: Brain CTA was performed for nine healthy beagle dogs using a bolus tracking method with saline flushing. A total dose of 600 mgI/kg of contrast agent with an iodine content of 370 mgI/mL was injected at a rate of 4 ml/s. Bone removal was achieved automatically by subtracting non-enhanced computed tomography (CT) data from contrast CT data. Five main intracranial arteries of the CoW were analyzed and graded on a scale of five for qualitative evaluation. Results: Scores of basilar artery, middle cerebral artery, and rostral cerebral artery in the BSCTA group were significantly higher than those in the NSCTA group (p = 0.001, p = 0.020, and p < 0.0001, respectively). Scores of rostral cerebellar artery (RcA) and caudal cerebral artery (CCA) did not differ significantly between the two groups. However, scores of RcA and CCA in the BSCTA group were higher than those in the NSCTA group. Conclusions BSCTA improved visualization of intracranial arteries of the CoW with close contact to bone. Thus, it should be recommended as a routine scan method in dogs suspected of having brain vessel disease.

Primary leiomyosarcoma rarely occurs in bone; when it occurs, it is more frequent in middle-aged individuals and frequently metastasizes to the lung. Here, we report a case of primary leiomyosarcoma of the femur in a 47-year-old woman who complained of pain in the left hip. The plain x-ray revealed an osteolytic lesion in the greater trochanter of the femur. The histopathological and immunohistochemical evaluation revealed a moderately differentiated leiomyosarcoma. Computed tomography of the chest and abdomen revealed no other potential primary lesions. The patient was diagnosed with primary leiomyosarcoma of the bone. Although surgical removal was recommended, the patient refused surgery. As an alternative, she was given radiotherapy and chemotherapy. No local progression or distant metastasis has been observed during the 4-year follow-up period.

A 38-year-old man who was diagnosed with malignant paraganglioma underwent computed tomography (CT) and I-131 metaiodobenzylguanidine (MIBG) san. CT showed extensive lymph node enlargement in right iliac area and retroperitoneum with severe hydronephrosis and mass on posterior bladder wall. However, I-131 MIBG scan didn't showed abnormal uptake. He also underwent F-18 fluorodeoxyglucose (FDG) positron emisson tomography/CT for localizing accurate tumor site. F-18 FDG PET/CT showed multiple metastases of left supraclavicular, hilar, mediastinal para-aortic, inguinal, right iliac lymph nodes, lung, vertebrae, and pelvis. There are a few reports showing that the F-18 FDG PET/CT is helpful for staging and localizing tumor site of patients who are diagnosed with negative on the MIBG scans. Thus, we report a case with paraganglioma which showed negative I-131 MIBG scan, but revealed multiple intense hypermetabolic foci in F-18 FDG PET/CT.

Liddle's syndrome is a rare inherited disease with characteristic clinical manifestations of hypertension and hypokalemic metabolic alkalosis. Markedly suppressed serum aldosterone and renin levels are important laboratory findings to differentiate this disorder from primary hyperaldosteronism. When Liddle et al. reported the disorder in 1963, they proposed aggressive Na+ absorption and increased excretion of K+ as the pathogenesis of the syndrome. Since then, specific mutation in the epithelial Na+ channel located in the collecting duct of the kidney has been elucidated as a disease mechanism. Liddle's syndrome is inherited by an autosomal dominant trait and generally the onset of the syndrome is before the age of 20 with increased risk of premature death due to stroke or heart failure. Recently, however, a few cases of late onset and genetically proven nonfamilial cases with de novo mutation of beta or gamma Na+ channel have been reported. We report a case of seventy-one year old woman who had hypertension with hypokalemic metabolic alkalosis and was diagnosed as Liddle's syndrome. Further evaluation revealed low serum renin and aldosterone levels. Primary aldosteronism, Cushing's syndrome, glucocorticoid remediable aldosteronism and deficiency of 11beta-OHase and 17alpha-OHase were ruled out based on her laboratory data and history. Her hypertension and hypokalemia responded to amiloride treatment but not to spironolactone.

Food-dependent exercise-induced anaphylaxis has been recognized a variant of exercise-induced anaphylaxis charaterised by symptoms occuring on exertion after certain meal. We experienced a patient who developed an anaphylaxis induced by wheat flour made food followed by exercise only in cold temperature. A 22-year-old male patient was presented urticaria, angioedema, dyspnea, and loss of consciousness induced by exercise after ingestion of wheat flour made food only in winter. Skin prick test was negative for wheat or bread but positive for mushroom. By contrast, RAST was positive for wheat and negative for mushroom. In order to confirm the diagnosis exercise challenge test was done. The attack developed after ingestion of wheat flour made food and 10 min of outdoor jogging in temperature about 10 degrees C, but not by indoor treadmill test in temperature about 20 degrees C or ingestion of mushroom. This is the first case of food-dependent exercise-induced anaphylaxis developed only in cold temperature in Korea.

The role of positron emission tomography (PET) with F-18 fluorodeoxyglucose (F-18 FDG) in the diagnosis of hepatocellulcar carcinoma (HCC) has been limited because of a variable FDG uptake in HCC. However, the usefulness of PET/CT for detecting extrahepatic metastasis and monitoring of the treatment response in HCC has been reported. A 55-year-old man with a hepatitis B surface antigen-positive, was admitted to our hospital due to dyspnea, general weakness and body weight loss for one month. Chest X-ray showed multiple reticulo-nodular densities on both lower lung fields, which implies metastatic lesions. F-18 FDG PET/CT revealed consecutively intense hypermetabolic mass in right hepatic lobe, inferior vena cava and right atrium. We report a case of HCC with IVC and right atrium invasion identified by F-18 FDG PET/CT.

F-18 fluorodeoxyglucose positron emission tomography (F-18 FDG PET/CT) plays an important role in diagnosis of malignant tumors and adds to conventional imaging in the staging of pertoneal carcinomatosis. However, false positive cases resulting from benign disease such as tuberculosis may occur. We report two cases of peritoneal tuberculosis on F-18 FDG PET/CT which showed multiple hypermetabolic foci in the mesentery and peritoneum with increased serum cancer antigen 125 (CA 125). Subsequent F-18 FDG PET/CT showed a disappearance of pathologic uptake following treatment with anti-tuberculosis drugs.
