Background: Phytoestrogens may be an alternative therapy in control of menopausal symptoms but their definite effects on breast tissue must be determined. Our study aimed to define the clinical and ultrasonographic changes of the breast after use of soy isoflavones in menopausal women. Materials and Methods: Menopausal women with hot flashes were randomly grouped as cases and controls and cases received soy isoflavones for 12 weeks. Breast examination (BE) and ultrasonography (US) were done at 0, 6 and 12 weeks. Tenderness and nodularity on BE were graded 1-4 by breast surgeons. Results: There were 30 women in the case and 26 in the control group. The mean age was 51.3 years and the mean age of menopause was 49.2 years. There was no change in the BE and US at 6 weeks in controls. In the case group, 10% had grade 1 tenderness and 13.3% grade 2 tenderness and grade 1 nodularity in BE accompanied with diffuse small cysts in US. At 12 weeks, there was no change in BE and US in the 2 groups. Conclusions: There was no statistically significant difference in the BE of the 2 groups at 6 and 12 weeks (p value=0.36 and 0.41 for nodularity and tenderness respectively) and in the US results. Although the literature contains many facts concerning PEs and the breast, further prospective studies are needed to identify structural breast changes produced by PEs in order to identify the appropriate dosage and indications of use.

Background: The purpose of this study was to investigate the correlation of contrast-enhanced ultrasonographic (CEUS) features with microvessel density (MVD) in papillary thyroid carcinomas (PTCs). Materials and Methods: Contrast-enhanced ultrasonography (CEUS) was performed in 62 patients (17 men and 45 women) with PTC. Tomtec software was applied to analyze the time intensity curve of CEUS. Immunohistochemistry was performed to evaluate the level of MVD in papillary thyroid carcinoma. Then the relationship between quantitative feature and the level of MVD was analyzed using SPSS 16.0 software. Results: The mean peak intensity of PTC tissues was lower than that of peripheral thyroid parenchyma ($61.9{\pm}11.8%$ vs 100%, p<0.05). The MVDs of CD34 and CD31 antibodies staining were $38.0{\pm}6.1$ and $37.9{\pm}5.1$ respectively in 62 PTC samples. A significantly positive correlation was observed between peak intensity and MVD in PTC tissues ($P_{CD34}$<0.01, $r_{CD34}$=0.838, $P_{CD31}$<0.01, $r_{CD31}$=0.837). Conclusions: The peak intensity in CEUS could reflect the MVD in PTC tissues. Therefore, quantification of CEUS seems to be helpful for assessment of MVD in PTC tissues.

Schistosoma mansoni is highly endemic in Tanzania and affects all age groups at different degrees. However, its control approach does not include adult individuals who are equally at risk and infected. To justify the inclusion of adult individuals in MDA programs in Tanzania, the present study focused on determining the prevalence of S. mansoni infection and its related morbidities among adult individuals. This was a cross sectional study conducted among 412 adult individuals aged 18-89 years living in selected villages of Rorya and Butiama districts located along the shoreline of the Lake Victoria. A pretested questionnaire was used to collect socio-demographic and socio-economic information of participants. Ultrasonographic examinations were conducted for all study participants using the Niamey protocol. A single stool sample was obtained from all study participants and examined for S. mansoni using the Kato-Katz technique. The study revealed a high prevalence of S. mansoni (56.3%), and the majority of infected individuals had a light intensity of infection. Ultrasonographic findings revealed that 22.4% of adult individuals had periportal fibrosis (PPF) (grade C-F), with 18.4% having grade C and D and 4% having grade E and F. Males had the highest prevalence of PPF (31.7% vs 10.8%, P<0.001). Organomegaly was common with 28.5% and 29.6% having splenomegaly and hepatomegaly, respectively. S. mansoni infection and its related morbidities included PPF, hepatomegaly, and splenomegaly were common among adult individuals. To reduce the level of transmission of S. mansoni infection, planned mass drug administration campaigns should include adult individuals living in these villages.

Ultrasonographic diagnosis of kidney and urinary bladder disease was performed in native Korea cattle. Ultrasonogaphic appearence of kidney and urinaryy baldder according to the growth were determined from 6 to 13 months by monthly examinations in 9 native Korean cattle. The kidney and urinary bladder were examined in standing position. The position, dimension, and structure of both kidneys were determined at 12 intercostal space and paralumbar fossa by use of ultrasonography. Ultrasonograms were obtained with 3.5 or 5.0-MHz sector transducer. The width and depth of the kidney, and the diameter of renal parenchyma and renal sinus were observed. Both kidneys were observedfrom the body surface until 8 months old age, but over the 9 months old age, only right kidney was easily accessible. The width of right kidney at the 6, 7, 8, 9, 10, 11, 12 and 13 months old age were 5.7, 6.3, 6.9, 7.6, 8.4, 9.3, 9.8 and 10.7 cm, respectively. The depth 5.8, 6.1 and 6.6 cm, respectively. The size of left kidney was similar to right kidney until 8 months old age. After the 9 months old age, only right kidney was easily accessible. The circumference of urinary bladder at the 6, 7, 8, 9, 10, 11, 12 and 13 months old age were 19.1, 21.7, 22.5, 23.0, 24.2, 25.3, 27.8 and 29.1 cm, respectively. Calculi in urinary bladder were observed by ultrasonography.

One fresh equine cadaver (two forelimbs) and five non-lamed thoroughbreds (ten sound forelimbs) were examined ultrasonographically through 5.0 MHz linear array transducer with a stand-off pad in palmar pastern region. The normal transverse ultrasonographic images of the superficial digital flexor tendon (SDFT), deep digital flexor tendon (DDFT), straight sesamoidean ligament (SSL), oblique sesamoidean ligament (OSL), and medium scutum could be identified at the region. The mean $\pm$ SD (min.$\sim$max. $mm^2$) of SDFT cross-sectional areas at P1A, P1B, P1C in the region were $110.00{\pm}5.38$ ($100{\sim}128$), $100.00{\pm}5.02$ ($90{\sim}111$), $114.00{\pm}3.33$ ($104{\sim}124$), respectively. The mean $\pm$ SD (min.$\sim$max. $mm^2$) of DDFT cross-sectional areas at each phalanx (P1A, P1B, P1C, P2A, P2B) were $136.00{\pm}4.83$ ($125{\sim}147$), $94.00{\pm}5.43$ ($85{\sim}108$), $99.00{\pm}4.87$ ($90{\sim}111$), $115.00{\pm}3.67$ ($108{\sim}124$), $135.00{\pm}3.65$ ($125{\sim}145$), respectively. The mean ratio of SDFT of P1B to DDFT was 0.74, 1.06, 1.01, 0.87, 0.74 at P1A, P1B, P1C, P2A, P2B, respectively.

Background : An increased frequency of reproductive endocrine disorders and polycystic ovary(PCO) has been reported in women with epilepsy. A possible role of the seizure disorder or, of the use of antiepileptic drugs(AEDs) has been suggested as the pathogenic mechanism. The objective of the present study was to assess the prevalence of reproductive endocrine disorders, such as PCO or menstrual abnormalities, in a series of women with epilepsy, examining the possible relationships of these disturbances with different epilepsy syndromes and AED treatment. Methods : Thirty epileptic women, all of reproductive age and none pubertal, pregnant, or lactating, were evaluated by clinical endocrinological assessment, and pelvic ultrasonography. Seven patients were on valproic acid(VPA), nineteen on carbamazepine(CBZ), and four on diphenylhydantoin(DPH) treatment, respectively. Results : Menstrual irregularity was observed in 8 women(26.7%), dysmenorrhea in 7(23.3%), and premenstrual syndrome in 1(3.3%). Ultrasonographic examination revealed that one women(3.3%) showed polycystic ovary, 4(13.3%) had ovarian cyst(s), and 2(6.7%) had uterine myoma, respectively. There was no difference in the prevalence of menstrual abnormalities or polycystic ovary according to the different preparations of AEDs. Conclusions : Data from this investigation suggest that, in Korean reproductive age women, the treatment of AEDs and the kind of medication may not have a significant effect on the prevalence of menstrual abnormalities or ultrasonographic polycystic ovary.

Spinoglenoid cyst have been reported in small series in the orthopaedic literature in association with SLAP lesion, which is one of less common causes of shoulder pain. Authors experienced one case of spinoglenoid cyst with SLAP lesion initially missed with ultrasonographic examination and physical examination. This case was confirmed by MRI, EMG and arthroscopic surgery was done. When clinicians cannot find a definite cause of shoulder pain and decreased power of rotator cuff tendon with ultrasonographic examination, they need further study such as MRI and EMG with careful physical examination. Clinicians need to aware of the limitation of ultrasonography for spinoglenoid cyst especially, (1) cyst size is small, (2) location of cyst is too deep to detect and along the scapula spine from SLAP lesion.

Two female Yorkshire terrier was referred to Veterinary Medical Teaching Hospital, Seoul National University. In case 1, clinical signs were vomiting, anorexia and weight loss. Cystic intraabdominal mass was identified in radiographic and ultrasonographic examination. In case 2, clinical sign was abdominal distension. In radiographic and ultrasonographic examination, cellular ascites and bilateral intraabdominal masses next to kidneys were observed. Many clusters of glandular epithelial cells with anisocytosis, anisokaryosis, high N:C ratio coarse chromatin and prominent nucleoli were shown in cytologic examination of sanguineous ascites. In all two cases exploratory laparotomy was performed and enlarged ovaries were observed (Rt: 6$\times$5$\times$5 cm and Lt: 3$\times$2$\times$1 cm in case 1 and 3$\times$2$\times$1 cm bilaterally in case 2). After ovariohysterectomy histopathologic examinations were performed. Histopathologically the masses were diagnosed as ovarian adenocarcinoma and ovarian cystadenocarcinoma in case 1 and case 2, respectively. In both dogs no further chemotherapy was carried out. These two dogs had no gross evidence of tumor recurrence at the time of 3 months after tumor resection, but long-term follow-up might be needed.

The aim of the study was to evaluate ultrasonographic findings, affected age, hematology, blood chemistry and clinical signs according to open or closed cervix in 102 bitches presented for treatment of pyometra. The prevalence of pyometra according to breed was observed in Maltese 22.5%, Yorkshire Terrier 13.7% and Shih Tzu 12.7%. The mean age of dogs was $9.6{\pm}0.3years$, and open cervix pyometra was more prevalent than closed cervix pyometra. Clinical signs included anorexia, vaginal discharge, depression, polyuria/polydipsia, vomiting, and abdominal distension. The concentration of BUN and the activity of ALP in dogs with closed cervix pyometra were significantly higher than those in dogs with open cervix pyometra (p < 0.05). The white blood cell and neutrophils in dogs with closed cervix pyometra were significant higher than those in dogs with open cervix pyometra (p < 0.05). Ultrasonographic findings of the uterus with open or closed cervix pyometra showed variable patterns. The uterine wall was variable in appearance, from thick and irregular to smooth and thin. The uterine wall was thicker in open cervix pyometra than in closed cervix pyometra. The luminal cavity included smaller amount of anechoic fluid in open cervix pyometra than in closed cervix pyometra.

The prevalence of liver and intestinal fluke infections was determined by surveying inhabitants of Hengxuan, Fusui, and Shanglin villages which were known to be endemic for liver flukes in Guangxi, China in May 2010. A total of 718 people were examined for helminth eggs by the Kato-Katz thick smear technique, ultrasonography, immunoaffinity chromatography, and DNA sequencing. The overall egg positive rate was found to be 59.6% (28.0-70.6%) that included mixed infections with liver and intestinal flukes. Cases showing higher than 20,000 eggs per gram of feces (EPG) were detected between 1.3% and 16.2%. Ultrasonographic findings exhibited overall 28.2% (72 of 255 cases) dilatation rate of the intrahepatic bile duct. Clonorchis sinensis infection was detected serologically in 88.3% (38 of 43 cases) among C. sinensis egg positive subjects by the immunoaffinity chromatography using a specific antigen for C. sinensis. For differential diagnosis of the liver and intestinal flukes, more precise PCR and nucleotide sequencing for copro-DNA were performed for 46 egg positive cases. Mixed infections with C. sinensis and Metagonimus yokogawai were detected in 8 of 46 egg positive cases, whereas 29 specimens were positive for Haplorchis taichui. Ultrasonographic findings and immunoaffinity chromatography results showed usefulness, even in a limited way, in figuring out of the liver fluke endemicity.
