For the study of the hemodynamic changes of the cranial pancreaticoduodenal arterial flow(cPDAF) in the dog with acute pancreatitis, acute pancreatitis was experimentally induced in 10 dogs by the injection of oleic acid into the accessory pancreatic duct. The parameters of cPDAF were measured by transcutaneous pulsed-wave Doppler ultrasonography. The hemodynamic changes included resistive indexe(RI), pulsatility index(PI) and maximum velocity (Vmax). Ultrasonographic scans were performed before the induction of pancreatitis and once daily for five days after the induction. The RI, PI and Vmax were increased with day as follows; the RI prior to induction was 0.625$\pm$0.096 (mean$\pm$SD), the PI was 1.117$\pm$0.289 and the Vmax was 0.349$\pm$0.094 m/s. After five days, the RI was 0.727$\pm$0.051 (p<0.0l), the PI was 1.480$\pm$0.284 (p<0.0l) and the Vmax was 0.585:$\pm$0.114 m/s (p<0.00l). These results show that there is some relation between the increase of the RI, PI and Vmax of cPDAF and the progress of acute pancreatitis in dogs. Therefore, the measurements of the hemodynamic changes of cPDAF may be a valuable technique for the evaluation of acute pancreatitis in dogs.

Objective: Ovarian reserve tests are commonly used to predict ovarian response in infertile patients undergoing ovarian stimulation. Although serum markers such as basal follicle-stimulating hormone (FSH) or random $anti-M{\ddot{u}}llerian$ hormone (AMH) level and ultrasonographic markers (antral follicle count, AFC) are good predictors, no single test has proven to be the best predictor. In this study, we developed appropriate equations and novel nomograms to predict the number of oocytes that will be retrieved using patients' age, serum levels of basal FSH and AMH, and AFC. Methods: We analyzed a database containing clinical and laboratory information of 141 stimulated in vitro fertilization (IVF) cycles performed at a university-based hospital between September 2009 and December 2013. We used generalized linear models for prediction of the number of oocytes. Results: Age, basal serum FSH level, serum AMH level, and AFC were significantly related to the number of oocytes retrieved according to the univariate and multivariate analyses. The equations that predicted the number of oocytes retrieved (log scale) were as follows: model (1) $3.21-0.036{\times}(age)+0.089{\times}(AMH)$, model (2) $3.422-0.03{\times}(age)-0.049{\times}(FSH)+0.08{\times}(AMH)$, model (3) $2.32-0.017{\times}(age)+0.039{\times}(AMH)+0.03{\times}(AFC)$, model (4) $2.584-0.015{\times}(age)-0.035{\times}(FSH)+0.038{\times}(AMH)+0.026{\times}(AFC)$. model 4 showed the best performance. On the basis of these variables, we developed nomograms to predict the number of oocytes that can be retrieved. Conclusion: Our nomograms helped predict the number of oocytes retrieved in stimulated IVF cycles.

Objective: Significant portion of premature ovarian failure patients ovulate intermittently and even can achieve pregnancy. The clinical features and reproductive potentials of Korean women with premature ovarian failure have never been elucidated. The purpose of this study is to assess ovarian follicular growth and ovulatory potential. Methods: Complete medical records of fifteen women with idiopathic premature ovarian failure were reviewed retrospectively. Subjects with more than 6 ultrasonographic scans and 36 months of follow-up period were included. Once the ovarian follicle was found by ultrasonography, the follicular growth was serially monitored. The result of ovulation induction of 6 cycles in 4 patients were also evaluated. Rate of positive ovarian follicle by ultrasound, rate of natural follicular growth and response of ovulation induction were assessed. Results: Among the 15 patients, 6 women (40%) had ovarian follicle in random ultrasonography. But the chance of positive follicle per ultrasonography scan was 7% (8 out of 115 scans). One out of 6 women eventually ovulated during the follow-up scan. In remaining 5 subjects, size of follicles remained unchanged. None of 6 ovulation induction cycles resulted successful ovulation. Conclusion: Incidence of positive ovarian follicle in Korean premature ovarian failure patients is lower than that of Western counterpart. This result, however, could not be directly compared because of the differences of study design. The ovulation rate by medical ovulation induction in this group is 0%, which is worse than the reported success rate of Western studies.
A ten-year-old female mongrel dog was presented to Veterinary Medical Center, Chungbuk National University with the signs of anorexia, weakness, and hemoglobinuria. Patient had been diagnosed as dirofilariasis based on heartworm antigen test and treated with adulticide (melarsomine) at local hospital one day before admission. On laboratory examinations, there were hypochromic and microcytic regenerative anemia, thrombocytopenia, moderate neutrophilia, and increase ALT, AST, and ALP. Radiographic exam showed main pulmonary artery bulging, pulmonary infiltration and hypervascularity, reduced abdominal serosal detail and mild hepatomegaly. Abdominal ultrasonographic exam showed mild peritoneal effusion and large hyperechoic thrombi at trifurcation of the porta hepatica and the splenic vein. In addition, intraluminal low density area and intravascular filling defect were confirmed on contrast enhanced CT scanning at the same anatomic locations. Patient was treated with anticoagulant and thrombolytic therapy. On day 42 after treatment, complete resolution of thrombi was confirmed via ultrasonography and improvement of clinical signs was observed.
A seven-year-old, castrated male Basset hound weighing 21.1 kg was presented for investigation of anorexia, lethargy, weight loss, melena and vomiting for 4 months. In laboratory findings, microcytic hypochromic anemia was identified, and other results were within a normal reference range. On the plain radiographs, soft tissue opacity was increased in the descending duodenal region; and on the contrast radiographs, ulcerative changes were identified in the entire segment of descending duodenum. Ultrasonographic findings included increased duodenal wall thickness and duodenal wall layering was lost. Endoscopy revealed irregular mucosal surface and luminal narrowing of the descending duodenum. There was concentrically thickened descending duodenum on the computed tomography. And the wall of the descending duodenum showed heterogenous enhancement after contrast agent injection. On histopathological findings, both chronic inflammation with mucosal proliferation and neoplastic changes with multiple small glandslike structures invading into the submucosa were identified. Based on these findings, presented case was diagnosed as an annular form duodenal adenocarcinoma. After 13 months of supportive medical treatment, the patient was expired. The purpose of this case report was to describe the duodenal adenocarcinoma in a dog.

Background: A forward head posture (FHP) is one of the most common types of poor head posture in patients with neck disorder. A prolonged FHP might increase pressure on the posterior cranio-cervical structure and exhibit reduced performance on a cranio-cervical flexion test (CCFT). CCFT is included to activate deep cervical flexor muscles and inhibit excessive activation of superficial cervical flexor muscles. Therefore, the selective activation of deep cervical flexors is needed for effective exercise for FHP. Objects: The purpose of this study was to compare muscle thickness between longus colli (Lco) and sternocleidomastoid (SCM) using ultrasonography in subjects with FHP depending on head support. Methods: This was a cross-sectional, case-control research design study. The ultrasonographic images of Lco and SCM were taken in 17 subjects with FHP during the 5 phases of the CCFT with and without a head support. Towel was used for supporting head to make the neutral head position in supine. Changes in muscle thickness during the test were calculated to infer muscle activation. Data were analyzed using repeated measures of two-way analysis of variance with the significance level of .05. Results: When subjects performed the CCFT with head support, there was a significant difference in muscle thickness of Lco and SCM (p<.05). According to a post hoc paired t-test, change of thickness of Lco was greater at all phases, and change of thickness of SCM muscle was less at phase 4 and 5 in condition with head support (p<.01) compared to condition without head support (p<.01). Conclusion: The result of this study suggest that applying head support for neutral head position during CCFT could be a useful method for activating Lco muscle without excessive activation of SCM muscle.
Background: Research efforts to improve the pulmonary function of people with limited chest function have focused on the diaphragmatic ability to control breathing pattern. Real-time ultrasonography is appropriate to demonstrate diaphragmatic mechanism during breathing. Objective: The purpose of this study was to investigate the effects of diaphragmatic breathing training using real-time ultrasonographic imaging (RUSI) on the chest function of young females with limited chest mobility. Methods: Twenty-six subjects with limited chest mobility were randomly allocated to the experimental group (EG) and control group (CG) depending on the use of RUSI during diaphragmatic breathing training, with 13 subjects in each group. For both groups, diaphragmatic breathing training was performed for 30-min, including three 10-min sets with a 1-min rest interval. An extra option for the EG was the use of the RUSI during the training. Outcome measures comprised the diaphragmatic excursion range during quiet and deep breathing, pulmonary function (forced vital capacity; FVC, forced expiratory volume in 1-sec; FEV1, tidal volume; TV, and maximal voluntary ventilation; MVV), and chest circumferences at upper, middle, and lower levels. Results: The between-group comparison revealed that the diaphragmatic excursion range during deep breathing, FVC, and middle and lower chest circumferences were greater at post-test and that the changes between the pretest and post-test values were greater in the EG than in the CG (p<.05). In addition, the subjects in the EG showed increased post-test values for all the variables compared with the pretest values, except for TV and MVV (p<.05). In contrast, the subjects in the CG showed significant improvements for the diaphragmatic excursion range during quiet and deep breathings, FVC, FEV1, and middle and lower chest circumferences after the intervention (p<.05). Conclusion: These results indicate that using RUSI during diaphragmatic breathing training might be more beneficial for people with limited chest mobility than when diaphragmatic breathing training is used alone.
Intraabdommal abscess usually causes distress with fever, leukocytosis, pain and toxicity. Diagnosis of intraabdominal abscess is occasionally difficult and It has high morbidity. However radiologic method, such as ultrasonography, CT scan, or RI scan are helpful to early detection of intraabdominal abscess. Among these methods, ultrasonography is a non-invasive technique and performed without discomfort to patient. And also differential diagnosis between cystic and solid lesion is very easy and sequential ultrasonography in same patient is valuable for the evaluation of treatment effect. We analyzed the ultrasonic features of 48 cases with intra-abdominal abscesses and the results are as follows; 1. In total 48 cases, the intra-abdominal abscesses were 30 cases, the retroperitoneal abscesses, 5 cases, and the visceral abscesses, 13 cases. 2. The causes of the intra-abdominal abscesses were perforating appendicitis (25 cases), postoperative complications (5 cases), pyogenic and amebic hepatic abscesses (13 cases), and the others (5 cases). 3. Round or oval shaped lesions were 26 cases (54%), irregular shape, 18 cases (38%), and multiple abscess formation in 4 cases (8 %). 4. The size of the lesions were between 5 and 10cm in diameter in 54% of total 48 cases, and the most frequent feature of the echo-pattern of the lesions was cystic with or without internal echogenicity (69%).
Acute pancreatitis(AP) in children is not common but can be associated with severe morbidity rates and its diagnosis is often delayed. Thus, reported mortality rates range from 0 to 78%. We have treated 26 patients with AP from 5 to 17 years of age over the past 17 years. We are intended to assess the relevance of the prognostic criteria used to assess severity of adult AP and to review the etiology, clilical presentation, diagnosis, and management of AP in children. The authors retrospectively reviewed 26 children with AP managed in Kyung Hee University Hospital from 1978 to 1995. Among 26 patients with AP, male were 12, and female were 14. And the mean age of patients was 11.8 years. In 9(34.6%), no definitive cause was identified. Common causes of AP were trauma(23.1%) and biliary tract disease(23.1%). Other etiologies were viral infection(15.4%) and post ERCP(3.8%). The presenting features were abdominal pain(92.3%), vomiting(61.5%), fever(19.2%), submandibular pain(11.5%), and abdominal mass(7.6%). Back pain was rare(3.8%). Abdominal ultrasonographic findings were abnormal in 10 of 16 patients(62.5%) and abdominal CT findings were abnormal for 9 of 9 patients(100%). Seventeen patients(65.3%) were managed conservatively, and nine patients(34.6%) required surgical treatment. There was no mortality. To evaluate the severity of disease, we used the Imrie prognostic criteria used to assess the severity in adult AP. The number of positive criteria was correlated to the duration of hospitalization(r2=0.91) but statistically insignificant(p>0.05). But, the number of positive criteria was correlated to the operative incidence(r2=0.93) and statistically significant(p<0.05). The common causes of AP in children were unknown origin(34.6%), trauma(23.1%), and biliary tract disease(23.1%). Ultrasonography and computed tomography were useful imaging tools of AP in children. The Imrie criteria used to evaluate the severity in adult AP were suspected to be valuable to assess the severity of AP in children.
Objective: To evaluate if there is any correlation between the growth rate of dominant follicles and clinical characteristics or outcome variables in women undergoing controlled ovarian hyperstimulation (COH). Methods: This study was performed in 313 in vitro fertilization (IVF) cycles. Follicle stimulating hormone (FSH), luteinizing hormone (LH) and estradiol (E2) were measured on day 3 of menstrual cycle, and serial ultrasonographic measurement of the diameter of growing follicles was performed. The growth rates of dominant follicles calculated by diameter difference divided by days were correlated with clinical characteristics and outcome variables. Results: There was no significant difference in the growth rate of the dominant follicles between gonadotropin releasing hormone (GnRH) agonist and antagonist cycles. No significant correlation was found between the growth rates and evaluated factors such as age, body mass index, LH, FSH, $E_2$, retrieved oocytes and fertilization rate. Conclusion: The Growth rate of dominant follicles seems to show an independent feature of basal characteristics and ovarian response.
