Pyometra is a diestrual, chronic disease process with acute manifestations in the adult, ovary-intact bitch. Serosal inclusion cysts develop during postpartum involution as mesothelium becomes trapped during rapid uterine contraction. A 10-year-old golden retriever bitch presented with lethargy, anorexia, tachypnea, abdominal distention, and abnormal vaginal discharge. Radiographic, ultrasound, and laboratory examinations were performed. On ultrasound examination, the uterus was distended by fluid containing echogenic "snow storm" particles; cystic structures containing anechoic fluid were found adjacent to the body of the uterus. Leukocytosis, neutrophilia, and anemia were diagnosed by a complete blood cell count. The initial diagnosis was pyometra, and an ovariohysterectomy was performed. Macroscopically, the uterine body and horns were expanded and partially adhered to the abdominal wall; numerous cysts containing clear fluid protruded over the entire surface of the uterus. Escherichia coli that was sensitive to enrofloxacin, was cultured from the lumen of the uterus. Histopathological assessment confirmed a final diagnosis of pyometra and serosal inclusion cysts of the uterus.

A 13-year-old, intact male, Yorkshire terrier dog with oliguria and hematuria was presented to the Small Animal Clinic at the Gyeongsang National University animal medical center. There were no remarkable findings on serum chemistry values and complete blood counts. Abdominal radiographs revealed mild elevation of the descending colon at the pelvic level. On the excretory urographic images, a large filling defect was identified in urinary bladder with narrow urinary bladder wall contact and there were no remarkable findings in kidneys and ureters. The abdominal ultrasonography revealed that an irregularly marginated, heterogeneous mass in urinary bladder, central cavitary lesion and mild vascular flow were also observed. Computed tomography showed a heterogeneously attenuated mass within urinary bladder. The mass was surgically excised, and leiomyosarcoma was confirmed by histopathological examination. The patient was followed up for two months and there were no complications. This case is of interest because of the unusual findings of leiomyosarcoma of urinary bladder in a small breed dog.

A 7-year-old female, Jindo dog was referred to the Veterinary Teaching Hospital with mild dyspnea and anorexia due to a gunshot trauma. The dog was wounded in the thoracic region 3 days ago. Plain radiographs showed the left 8th rib fracture, interstitial pattern in the left caudal lung field and pleural effusion. Abdominal radiographs showed the lead bullet. Computed tomographs(CT) showed the size of pulmonary contusion, laceration, lung parenchymal injuries, hemothorax and perforation of abdominal wall. The therapeutic plan was based on abnormalities seen on CT scans but not clearly seen in survey radiographs. Thoracic CT significantly provides even more informations compared with the corresponding radiographs in thoracic gunshot trauma. Although thoracic survey radiographs are useful as a screening tool, CT is highly sensitive in detecting thoracic injuries after thoracic trauma and is superior to routine thoracic survey radiographs in visualizing lung contusion, pneumothorax and hemothorax. Therefore, we recommend CT in the initial diagnostic work-up of patients with thoracic injuries and with suspected chest trauma because early and exact diagnosis of all thoracic injuries along with sufficient therapeutic consequences may reduce complications.

In this paper, we proposed a non-contact respiration measurement system with ultrasonic proximity sensor. Ultrasonic proximity sensor approach of respiration measurement which respiration signatures and rates can be derived in real-time for long-term monitoring is presented. 240 kHz ultrasonic sensor has been applied for the proposed measurement system. The time of flight of sound wave between the transmitted signal and received signal have been used for a respiration measurement from abdominal area. Respiration rates measured with the ultrasonic proximity sensor were compared with those measured with standard techniques on 5 human subjects. Accurate measurement of respiration rate is shown from the 50 cm measurement distance. The data from the method comparison study is used to confirm the performance of the proposed measurement system. The current version of respiratory rate detection system using ultrasonic can successfully measure respiration rate. The proposed measurement method could be used for monitoring unconscious persons from a relatively close range, avoiding the need to apply electrodes or other sensors in the correct position and to wire the subject to the monitor. Monitoring respiration using ultrasonic sensor offers a promising possibility of non-contact measurement of respiration rates. Especially, this technology offers a potentially inexpensive implementation that could extend applications to consumer home-healthcare and mobile-healthcare products. Further advances in the sensor design, system design and signal processing can increase the range of the measurement and quality of the rate-finding for broadening the potential application areas of this technology.

Purpose: Paragonimiasis is infectious disease occurred by Paragonimus Westermani, which invades into human body as a final host. Habitual eating the freshwater crab or crawfish unboiled is one of the reason of infection. Paragonimiasis raged in 1970s in Korea, Japan, China and other Asian countries but the incidence decreased rapidly. Once people eat infected second host, parasite penetrates the duodenal wall and migrates to the lung. During this migration period, the parasite can migrate to other organ, such as brain, spinal cord, liver and subcutaneous tissue, but the cases are rarely reported. The objective of our study is to present our experience of the ectopic migration of parasite to the subcutaneous tissue of the abdomen, which was easily treated with excision and Praziquantel medication. Methods: A 59-year-old woman who likes eating unboiled freshwater crab was diagnosed as Paragonimiasis 15 months ago. Her symptoms were fever and cough, and she was treated with Praziquantel medication. 3 months after discharge, she visited our hospital with left pleuritic chest pain, cough with fever, and palpable mass formation on left lower quadrant of the abdomen. Wedge resection of the left lung and Praziquantel medication was maintained for a week. Nevertheless, fever persisted after the treatment. The patient received total excision of the abdominal soft tissue mass, and the fever was relieved. Results: Pathologic findings of the mass showed multiple cyst and abscess formation with crystal structure which is suspicious parts of the parasite or calcified egg shells. Uncontrolled fever was relieved after the operation, and there was no evidence of recurrent Paragonimiasis and ectopic migration for 1 year follow up period. Conclusion: Ectopic migration of Paragonimus is rare, but multiple organ can be involved. Patient with Paragominiasis who was refractory in fever control after Praziquantel medication or surgical evaluation of the lung should be considered as ectopic migration of the Paragonimiasis.

A 3-year-old intact mixed hunting dog was referred to Gyeongsang Animal Medical Center with the clinical signs of vomiting, dyspnea, anorexia. The dogs had traumatic history that wounded at abdominal wall during the wild boar hunting 2 week ago. The dogs was diagnosed as extrahepatic biliary tract obstruction (EHBO) secondary to traumatic hernia. Diagnosis was based on radiographic features of a diaphragmatic hernia on survey radiography, dilated bile duct in abdominal ultrasonography and complete recovery due to the return of displaced organs into the peritoneal cavity and repair of the diaphragmatic rent. Diagnostic imaging and surgical intervention may result in a favorable outcome in dog with post hepatic obstruction secondary to diaphragmatic hernia. This case emphasizes the strangulation of bile duct by diaphragmatic rupture could be the cause of EHBO.

Objectives: Although Campylobacter is the main cause for bacterial acute gastroenteritis (AGE), there has been no notable clinical research into it, especially for Korean children. In this study, we share our experience of clinical, laboratory and image findings with Campylobacter AGE. Methods: Between May 2013 and June 2016, children diagnosed as having Campylobacter AGE were retrospectively enrolled in our study. Campylobacter AGE was considered diagnosed when a patient had symptoms of bacterial AGE and a positive Campylobacter result in stool using multiplex PCR. Results: Among 539 patients with suspected bacterial AGE, 31 (5.8%) patients had a positive result for Campylobacter. The average age of the 31 patients was $10.2{\pm}5.0$ years with a range between 1.1 and 16.9 years. Eighteen (58%) of the total patients were hospitalized between June and August. Diarrhea (93.5%), abdominal pain (83%) and fever (83%) were common symptoms. For 20 patients (65%), diarrhea lasted for less than three days, and fever lasted for 2.1 days on average. Among the 20 patients subjected to imaging studies, 12 patients (60%) showed bowel wall thickening on the right side of colon. In blood tests of 30 patients, 22 (73%) and 29 (97%) patients exhibited leukocytosis and elevated C-reactive protein, respectively. During treatment for Campylobacter AGE, prediagnostic empirical antibiotics were used for 6 (19%) patients. All patients recovered without complications. Conclusions: Among the children with suspected bacterial AGE, 5.8% had a positive result on Campylobacter in stool using multiplex PCR. Therefore, we observe that Campylobacter AGE should be considered in school-age children who have diarrhea, fever, and abdominal pain.

Objective: The aim of this study was to compare the effects of different doses of Geumnyeonyijin-tang (GNYJT) water extracts with those of metformin (250 mg/kg) in mild diabetic-obese mice. Methods and Results: The 48 mice were divided into 1 normal pellet diet (NFD) group and 5 high-fat diet (HFD) groups. At the end of 12 weeks of oral administration of metformin (250 mg/kg) or GNYJT water extracts (400, 200, or100 mg/kg), the effects were evaluated. The HFD control mice showed noticeable increases in body weight, adipose tissue density, fat pad weight of the periovarian and abdominal wall, and insulin, blood glucose, and HbA1c levels, with decreases in serum HDL levels. Increases in the periovarian and dorsal abdominal fat pad, regions of steatohepatitis, adipocyte hypertrophy, and hepatocyte hypertrophy were also discovered. The HFD group showed a decline in glucose levels and elevation of hepatic gluconeogenesis, suggesting an HFD-induced AMPK downregulation related to glucose dysregulation, as well as lipid metabolism related to obese insulin-resistant type II diabetes, dyslipidemia, and oxidative stress related diabetic hepatopathy (non-alcoholic fatty liver disease, NAFLD). Conclusion: Assessment of the key parameters for inhibition of diabetes and related complications in HFD-fed diabetic-obese mice demonstrated that GNYJT water extracts have favorable ameliorating effects. The effect of GNYJT was manifested through the stimulation of AMPK upregulation of related hepatic glucose enzyme activities and expression of lipid metabolism-related genes. Therefore, appropriate oral dosages of GNYJT could be promising as a new preventive candidate for controlling diabetes and related complications. Further screening of biologically active compounds, elucidation of detailed mechanisms, and more animal studies are warranted.

Backgrounds/Aims: Acute cholecystitis is a rare condition in pregnant women, potentially affecting the maternal and fetal prognosis. Our aim was to report the main clinical and paraclinical features of acute cholecystitis during pregnancy and therapeutic modalities. Methods: We conducted a case series analysis recording pregnant patients with acute cholecystitis admitted to our surgery department over a period of 11 years. We collected clinical data, paraclinical features, and management modalities related to cholecystitis. Results: There were 47 patients. Twenty-eight percent was in the first trimester of pregnancy, 40% in the second, and 32% in the third trimester. Abdominal pain was located in the right hypochondrium in 75% of cases. Fever was noted in 21% of cases. C-reactive protein was elevated in 39% of patients. Cholestasis markers were high in four patients. Abdominal ultrasound showed a distended gallbladder in 39 patients, with thickened wall in 34 patients, and gallbladder lithiasis in all cases. No patient had a dilated main bile duct. All patients received intravenous antibiotic therapy. Tocolysis was indicated in 32 patients. Laparoscopic cholecystectomy was performed in 32 cases (68%), and open cholecystectomy in 15 cases (32%). Postoperative course was uneventful in 42 patients, and complicated in 5 patients. Rate of complications was statistically higher after open cholecystectomy (p = 0.003). Morbidity rate was higher in the third trimester (p = 0.003). Conclusions: Delay in the diagnosis of acute cholecystitis during pregnancy can lead to serious complications. Management is based on antibiotic therapy and cholecystectomy. Laparoscopic cholecystectomy appears to be less morbid than open cholecystectomy.

Massive localized lymphedema (MLL) is a rare disease caused by the obstruction of lymphatic vessels with specific clinical morphological and radiological characteristics. People with morbid obesity are mainly affected by MLL. Lymphedema is easily confused with soft tissue sarcoma and requires differential diagnosis, both the possibility of an MLL and also carcinoma manifestations in the soft tissues. The possible causes of massive lymphedema include trauma, surgery, and hypothyroidism. This report is the first case of MLL treated surgically in the Russian Federation. Detailed computed tomography (CT) characteristics and an electron microscope picture of MLL are discussed. A 50-year-old woman (body mass index of 43 kg/m²) with MLL arising from the anterior abdominal wall was admitted to the hospital for surgical treatment. Its mass was 22.16 kg. A morphological study of the resected mass confirmed the diagnosis of MLL. We review etiology, clinical presentation, diagnosis, and treatment of MLL. We also performed an electron-microscopic study that revealed interstitial Cajal-like cells telocytes not previously described in MLL cases. We did not find similar findings in the literature. It is possible that the conduction of an ultrastructural examination of MLL tissue samples will further contribute to the understanding of MLL pathogenesis.
