To evaluate of the ultrasonographic changes in hemiplegic and unaffected knee joints of hemiplegic ambulators with recent onset stroke. Twenty patients (40 knees) with prevalence duration of 14-39 weeks (mean 24.70 weeks) after a stroke insult were included. All participants were walking independently without leg dragging, had no previous knee injury. There were significant differences in intercondylar cartilage thickness and pes anserinous tendinopathy (PAT) between hemiplegic and unaffected knees (p<0.05). There were no differences in cartilage thickness of medial condyle and lateral condyle, patellar tendinitis/bursitis, suprapatellar effusion, synovitis, joint space narrowing, and Baker's cyst of ultrasonographic findings and x-ray findings in hemiplegic knee compared to the control except PAT (p<0.05). In hemiplegic knee, medial or lateral condylar cartilage thickness was significantly correlated with body weight, intercondylar cartilage thickness, and PAT (p<0.05). PAT was significantly correlated with Brunnnstrom stage and condylar cartilage thickness (p<0.05). Knee pain was significantly correlated with lateral condylar cartilage thickness (p<0.1). The hemiplegic knee had more ultrasonographic abnormalities including PAT and more cartilage thickness preservation in patient with recent onset stroke. Intraarticular sonographic findings including cartilage thickness was significantly correlated with extraarticular findings including PAT and a symptom of knee pain.

Purpose: The aim of this study was, firstly, to determine the concordance of ultrasonographic and histopathological diagnoses in patients in whom apical resection was already indicated. Secondly, this study aimed to determine whether lesions were periapical granulomas or cysts, and to compare them after root canal treatment using ultrasonography and periapical radiographs. Materials and Methods: In the first stage of the study, ultrasonographic and histopathologic diagnoses of 10 lesions were compared. Secondly, the periapical radiographs and ultrasonographic images of 44 lesions were measured. The presence of internal vascularity was determined by ultrasonographic color and power Doppler modes. Follow-up examinations of healing after root canal treatment were performed using ultrasonography and periapical radiographs, and these modalities were compared. Results: In the periapical granuloma and cyst groups, the measurement values decreased for all variables. There was no significant difference in the dimensional changes of lesions between the 2 groups, and ultrasonography and periapical radiographs were compatible. The pre-diagnoses were compared with histopathological diagnoses and were found to be compatible. Conclusion: The ultrasonographic color and power Doppler techniques could be an effective method for diagnosing periapical lesions as cysts or granulomas. After root canal treatment of granulomas and cysts, the dimensional shrinkage and healing patterns appear to be similar. Ultrasonography and periapical radiographs were consistent in terms of dimensional comparisons, and ultrasonography may be an alternative method for follow-up of the healing of periapical lesions.

5 years Poodle was referred to the Veterinary Teaching Hospital, Chonnam National University in January 1997, with progressive swelling on the rear xiphoid process after cesarean section last year in local-vet clinic. Physical, radiographic, ultrasonographic and intraoperative findings that were obtained from this case were as follow; Physical findings were known as no pain, no fever in the hernia] sal at palpation. Radiographic findings revealed the decreased density of swelling contents more than peritoneum and did not identify the abdominal wall defect line. Ultrasonographic findings showed abdominal wall defect line of 3mm and intra-abdominal originated fat contents with mixed echo(hypoechoic). During the operation, falciform ligament into the hernial sac was observed and not excised, manipulated back into the cavity. The dog was given an herniorraphy with no recurrence and infection.

Purpose: It is not always easy to determine the existence of tendon injuries when it comes to patients with finger lacerations. Thus, we tried to find the difference in effectiveness and in compliance of patients when we employed two different types of diagnosis, conventional gross confirmation and ultrasonographic confirmation. Methods: From December 2009 to March 2010, we enrolled 14 patients with finger tendon injury at Soonchunhyang University Cheonan Hospital. The median age of the patients was $35.9{\pm}14.4$, and the ratio of females to males was 1:2.5 We evaluated the compliance of each patient by measuring four different categories (level of cooperativeness in showing their wound and in following the instructions, level of movement of their fingers during the diagnosis and total number of attempts to diagnose) by using a score from 1 to 3 for each category, for a total possible score of 12 for each patient. We also measured the painfulness of each patient by using a score of 1 to 10 and the time required for each diagnosis. Results: The levels of patients' compliance was $8.9{\pm}2.1$ when diagnosed with gross confirmation and $9.8{\pm}2.1$ when diagnosed with ultrasonographic confirmation (p value=0.042). The pain score of the patients was $3.7{\pm}1.7$ with gross confirmation and $2.9{\pm}1.2$ with ultrasonographic confirmation (p value=0.020). The median duration of time in each test was $6.7{\pm}4.8$ minutes with gross confirmation and $10.5{\pm}4.2$ minutes with ultrasonography (p value=0.006). Conclusion: Comparing gross confirmation and ultrasonographic confirmation, gross confirmation is a better method than ultrasonography because of time efficiency. However, ultrasonographic confirmation has advantages over gross confirmation in pain scale and better compliance of patients. Emergency physicians generally employ gross confirmation rather than ultrasonography in determining the existence of tendon injury in patients. In patients with finger lacerations without bone injury, ultrasonography can be considered as a secondary diagnostic tool, especially when patients have much pain.

The purpose of this study was to investigate the correlation between ultrasonographic findings used to diagnose and assess of torticollis and a overall special assessment of congenital muscular torticollis in infants. Seventy-eight subjects with congenital muscular torticollis participated in this study. All the patients were divided into one of four clinical types according to the sternocleidomastoid muscle fibrosis noted on the ultrasonographic findings, and they were divided into one of three subgroups according to the degree of disability on the overall special assessment score of torticollis. For the ultrasonographic classifications of the 78 patients, 42(53.8%) made up the first type, 21 (26.9%) made up the second type, 7 (9.0%) made up the third type, and 8 (10.3%) made up the fourth type. Multivariate analysis of the results showed that the age at presentation was significantly different according to the ultrasonographic subtypes (p<0.01). There was significant correlation between the ultrasonographic findings and the torticollis overall assessment for patients with congenital muscular torticollis (${\phi}$=0.893, p<0.01). According to the results of this study, the use of the simple and objective torticollis overall assessment will be useful for the evaluation of torticollis in the future.

This study was carried out to analyze the utilization of ultrasound machines in animal hospitals and focused on surveying the present condition of diagnostic ultrasound on veterinary medicine in South Korea. Total 279 veterinary hospitals were surveyed with e-mail questionnaires or telephone survey. E-mail questionnaires consist of 17 items of questions including existence of ultrasound machine, types of ultrasound machine, ultrasound examination costs, frequency, purposes, other diagnostic imaging equipments, and referring system of ultrasound. Telephone surveys asked about the existence of the ultrasound machine and types of the ultrasound machine to 279 animal hospitals. Two hundred and seventy-one out of 279 animal hospitals holds ultrasound machine. Seventy-two percents clinics purchased used ultrasonographic machines and mean years after the date of manufacture is 7.5 years and the proportion of superannuated machines are relatively high. Also many clinicians prefer single organ scanning rather than general scan technique and more than 60% of clinics perform ultrasonographic examination less than 5 times a week. Clinics located in Seoul area tend to have more expensive and brand-new ultrasonographic machines and the distribution of radiology specialist are higher in this area. Problems associated with the present condition were oversupply of machines, unequal distribution of the medical equipment in different localities, ineffective use of the medical equipment, and high percentage of old poor-quality medical equipments. There should be a viable alternative proposal to control amount and quality of the ultrasound machines. Also, the improved management system for the ultrasound machine is required.

Purpose: This study clarified the bacterial pathogens currently causing acute infectious enterocolitis (AIE) in children and evaluated the clinical characteristics and ultrasonographic findings according to the different pathogens. Methods: Medical records regarding age, sex, clinical symptoms, laboratory data, identified enteropathogens, ultrasonographic findings, treatment, and outcome of 34 patients who were diagnosed with AIE via stool examination using multiplex polymerase chain reaction (PCR) or culture, were retrospectively reviewed. Results: Twenty-four patients (70.6%) were male. The mean age of the patients was $8.5{\pm}6.2$ (range, 1.1-17.1) years. Six bacterial pathogens were isolated: Salmonella species (spp.) (32.4%), Campylobacter spp. (20.6%), verotoxin-producing Escherichia coli (14.7%), Staphylococcus aureus (11.8%), Clostridium difficile (8.8%), and Shigella spp. (2.9%). Abdominal pain occurred in all patients regardless of pathogen. The patients infected with Salmonella were older than those infected with verotoxin-producing E. coli (p<0.05). C-reactive protein levels were higher in patients with Salmonella and Campylobacter infections than in those with verotoxin-producing E. coli infection (p< 0.05), the other clinical and laboratory data were indistinguishable between pathogens. Ultrasonography demonstrated diverse involvement of bowel segments according to pathogen. Wall thickening of both the ileum and the entire colon was the most common lesion site regardless of pathogen. Conclusion: Various bacterial agents cause AIE and the symptoms are diverse symptoms, however, all most children recovered spontaneously. Use of multiplex PCR on stool samples warrants improvement of its sensitivity for diagnosis of enteropathogenic bacteria. Ultrasonographic examination is useful for diagnosis of AIE; it can also detect the disease extent and severity.

Ultrasonographic study was undertaken to establish the echogenecity and size of reproductive organs of 18 cycling buffaloes of different parities and compared with the sizes measured by palpation per rectum at estrus (day 0), met estrus (day 2), mid diestrus (day 10) and late diestrus (day 16). The overall mean size of cervix, uterine body, right horn, left horn, right ovary and left ovary measured by palpation per rectum were 2.70$\pm$0.43, 2.36$\pm$0.36, 2.17$\pm$0.37, 2.12$\pm$0.38, 2.63$\pm$0.41 and 2.72$\pm$0.37 cm, respectively. The corresponding ultrasonographic observations were 2.10$\pm$0.40, 1.85$\pm$0.30, 1.73$\pm$0.36, 1.64$\pm$0.37, 2.16$\pm$0.36 and 2.29$\pm$0.38 cm respectively. Variations in the size of genitalia due to stages of estrous cycle were non-significant. The size of genitalia measured by palpation per rectum was significantly higher (p<0.05) than by ultrasonography. However, there was linear positive correlation (r=+0.87) in the measurements by the two techniques. The ultrasonographic characteristics of tubular genitalia revealed different echogenic gray shades around the nonechogenic (black) central area of lumen depending upon the stage of cycle. The ovarian stroma appeared as hyperechoic (white) area with nonechogenic (black) follicle. The corpus luteum (CL) exhibited different echogenic texture viz. grayish black, grayish granular and grayish white at met estrus, mid diestrus and late diestrus, respectively. Therefore, ltrasonography can be effectively employed to record the exact size and echotexture of the buffalo genitalia during different stages of estrous cycle.
