    To evaluate serial ultrasonographic findings of fungal myositis in children. Eleven lesions caused by fungal myositis and occurring in six children were included in this study. Eight lesions in five children were histopathologically proven and the other three were clinically diagnosed. Serial ultrasonographic findings were retrospectively evaluated in terms of size, location, margin, internal echotexture and adjacent cortical change occurring during the follow-up period ranging from five days to two months. Three patients (50%) had multiple lesions. The sites of involvment were the thigh (n=4), calf (n=3), chest wall (n=2), abdominal wall (n=1) and forearm (n=1). Initially, diffuse muscular swelling was revealed, with ill-defined hypoechoic lesions confined to the muscle layer (n=8). Follow-up examination of eight lesions over a period of 5-10 days showed that round central echogenic lesions were surrounded by previous slightly echogenic lesions (n=6, 75%). Long-term follow-up of five lesions over a two-month period revealed periosteal thickening in one case (20%), and the peristence of echogenic solid nodules in four (80%). Pathologic examination showed that the central lesions correlated with a fungus ball and the peripheral slightly echogenic lesions corresponded to hematoma and necrosis. Serial ultrasonographic findings of fungal myositis in children revealed relatively constant features in each case. In particular, the findings of muscular necrosis and a fungus ball over a period of 5-14 days were thought to be characteristic.

    To evaluate the serial ultrasonographic findings of experimental intramuscular hemorrhaging to determine if there is a correlation with the pathologic findings. An ultrasonography (US) was performed before and immediately after an intramuscular blood injection in nine rabbits. In addition, follow-up US images were obtained at 1, 4, 7, 10, 14, 21, and 28 days after the intramuscular blood injections in seven of the rabbits. The pathologic specimens, compared to the US findings on each date, and consisted of samples of left thigh muscle. A US, performed immediately after a blood injection, showed two patterns; 6 cases of hyperechoic muscle thickening and 3 cases of hyperechoic muscle thickening with extravasation between the epimysium and muscle bundle or within muscle bundle. A follow-up US showed a marked decrease in intramuscular hemorrhaging and microcalcifications, which appeared on the 4th, 7th and 10th day after the blood injection. The pathologic findings revealed several short echogenic lines in the muscular bundles which were hemosiderin. Moreover, a 28 day follow-up US revealed that the normal findings are correlated with the normal gross pathologic findings. The US findings of the intramuscular hemorrhaging, for each of the follow-up dates, in comparison to the pathologic findings, revealed a high correlation with the pathologic specimens. Consequently, a US transducer with high resolution can be considered as a helpful technique in the diagnosing and evaluating the follow-up treatment of intramuscular hemorrhaging

    Postpartum changes in uterine shape, architecture, echogenicity and diameter were determined during the serial examinations of five beagle bitches. During postpartum Week 1, the uterine horns were tubular structures composed of multiple layers of various echogenicity and had multiple, discrete enlargements with hypoechoic centers at placental sites. Diameters ranged from 1.1 to 3.8 cm at placental site enlargements, and 0.5 to 1.4 cm between enlargements. Uterine involution appeared to be completed by 15 wk post partum. At 15 weeks the uterine horns of each dog were uniform hypoechoic, tubular structures without enlargements and had a reduced diameter of 0.3 to 0.6 cm. These ultrasonographic findings are similar to previously reported gross and light microscopic descriptions of canine uterine involution.

    To evaluate the usefulness of ultrasonographic findings of the common extensor and flexor tendon in evaluation of patients with lateral and medial epicondylitis. Thirty eight elbows from twenty four patients (mean age=45.2 years) were included. Ultrasonographic examination was performed to evaluate lateral or medial epicondylitis. Epicondylitis was divided into five groups according to the severity of disease: 1) normal, 2) tendinopathy, 3) tendinopathy with a partial tear, partial tear and 4) complete tear. Change in the size of a tendon, bony change of the epicondylitis, presence or absence of calcification or echogenic foci in the common tendon and hypervascularity for each categories were also assessed. In addition, these lesions were divided into the superficial and deep according to the location of lesions. According to the severity, there were 15 cases of normal, 13 tendinopathies, 8 tendinopathies with a partial tear, 2 partial tears and 0 complete tear. Bony change was seen only in tendinopathy, tendinopathy with partial tear and partial tear. Calcification or echogenic foci were only observed in cases with tendinopathy and tendinopathy with partial tear. Hypervascularity was only seen in one case of tendinopathy. With thorough understanding of ultrasonographic findings of epicondylitis, ultrasonographic examination can be especially useful and effective in evaluating the severity and location of lesions.

    To evaluate the ultrasonographic findings of the patients with sclerosing encapsulating peritonitis (SEP). Thirteen patients with surgically confirmed sclerosing encapsulating peritonitis were involved in this study. Because of intestinal obstruction, all patients had received operations. Among 13 patients, 12 cases had continuous ambulatory peritoneal dialysis (CAPD) for 2 months-12 years and 4 months from (mean; 6 years and 10 months), owing to chronic renal failure and one patient had an operation due to variceal bleeding caused by liver cirrhosis. On ultrasonographic examination, all patients showed loculated ascites which were large (n=7) or small (n=6) in amount with multiple separations. The small bowel loops were tethered posteriorly perisaltic movement and covered with the thick membrane. The ultrasonographic of findings of sclerosing encapsulating peritonitis were posteriorly tethered small bowels covered with a thick membrane and loculated ascites with multiple septa. Ultrasonographic examination can detect the thin membrane covering the small bowel loops in the early phase of the disease, therefore ultrasonography would be a helpful modality to diagnose SEP early.

    To investigate predictable ultrasonographic findings of early abortion. To investigate objective rules for the screening of abortion. Ultrasonographic examination of 111 early pregnancies between the sixth and ninth week in women who had regular 28 day menstrual cycles was performed. Ultrasonographic measurements of the gestational sac, crown rump length and fetal heart rate were performed using a linear array real time transducer with doppler ultrasonogram. All measurements of 17 early abortions were compared to those of 94 normal pregnancies. Most of early aborted pregnancies were classified correctly by discriminant analysis with G-SAC and CRL (G-SAC=0.5 CRL + 15, sensitivity 76.5%, specificity 96.8%). With the addition of FHR, 94.1% of early abortions could be predicted. In conclusion, ultrasonographic findings of early intrauterine growth retardation, small gestational sac and bradycardia can be predictable signs suggestive of poor prognosis of early pregnancies

    To evaluate the ultrasonographic findings of lateral epicondylitis and their relationship with clinical outcome. The findings of ultrasonographic examinations of eighteen elbow joints in 15 patients (M:F=5:10; age:38-65(mean, 47.6) years) with lateral epicondylitis were reviewed. Two patients underwent surgery, two were not treated, and the remaining 11 were treated conservatively. Symptomatic improvement was noted 1 week after conservative treatment in two cases, at 2 weeks in five cases, at 3 weeks in three cases, and at 5 weeks in one case. With patients in the 90 degree flexed elbow position and in a supinated wrist, weexamined the extensor carpi radialis brevis (ECRB) tendon around the lateral epicondyle using ultrasound equipment with a 7-11 MHz linear transducer. The findings were assessed in terms of swelling of the tendon, changes in its echotexture, the presence of calcification of cystic degeneration, loss of the hypoechoic band between the tendon and bony cortex of the lateral epicondyle, cortical irregularity of the lateral epicondyle, and fluid collection around the tendon. Any relationships between each ultrasonographic finding and the treatment interval after which symptomatic improvement was noted were evaluated. In the 18 joints, change was heterogeneous hypoechogenicity in 13, and heterogeneous mixed echogenicity in three. Other ultrasonographic findings were swelling of the tendon in ten cases, loss of the hypoechoic band in 14, cortical irregularity in five, calcification in four, cystic degeneration in nine, and fluid collection around the tendon in four. In patients treated conservatively, there was no statistically significant difference between each ultrasonographic finding and the treatment interval after which symptomatic improvement was noted. Ultrasonography can be used to assess changes in the ECRB tendon and lateral epicondyle occurring in lateral epicondylitis, but fails to provide information on the rapidity of symptomatic

    Alkaptonuria is a rare disease with autosomal recessive inheritance and variable expression. The weight-bearing joint involvement and spondylitis-like vertebral changes occur only after the 3rd decade. Musculoskeletal ultrasonographic findings in alkaptonuria were only rarely described, consisting mainly into enthesopathy and non-synovial tendon degeneration. We present the case of a 50 years old man with alkaptonuria and discuss the ultrasonographic findings and the relationship of the disease with chondrocalcinosis. The tendinous and synovial aspect may be peculiar and it could therefore allow recognition and screening for alkaptonuria, along with clinical and radiologic data.

    To evaluate the ultrasonographic characteristic of a rare malformation comples, Cloacal anomaly on prenatal ultrasonography. From March 1991 to July 2001, eight cases with the persistent cloaca (4 cases in female and 1 case in male) and cloacal exstrophy (3 cases) diagnosed by prenatal ultrasound examination were included, and all of them were pathologically confirmed by autopsy. One radiologist retrospectively analyzed the prenatal sonographic images, including the urinary bladder, kidney, pelvic cyst, abdominal wall defect and amount of amniotic fluid. The ultrasonographic diagnosis was established at 21.8 {+-} 7.8 weeks of gestation. The prenatal ultrasonographic findings of the persistent cloaca were absent bladder (n=2), distended bladder (n=2) and small thick bladder (n=1). Sonography of the kidney showed normal (n=2), hydronephrosis (n=1), dysplasia (n=1) and unilateral hydronephrosis with absent contralateral kidney (n=1). Four fetuses showed septated pelvic cyst; three fetuses, oligohydramnios. The prenatal ultrasonographic findings of cloacal exstrophy included absent bladder (n=3), normal kidney (n=1), hydronephrosis (n=1) and absent kidney (n=1). All fetuses with cloacal exstrophy had abdominal wall defect while two of them had oligohydramnios. A prenatal diagnosis of persistent cloaca can be confidently made when there is septated pelvic cyst combined oligohydramnios, sediments within the cyst and intraluminal calcifications. Cloacal exstrophy should be included in diagnosis if there is a low abdominal wall defect with absent urinary bladder.

    Endometriosis in the abdominal wall is a rare condition that most commonly occurs in the physiological scar of the umbilicus and in surgical scars of pelvic operation. The ultrasonographic findings are often non-specific, but with scrutinized physical examination and history, correct diagnosis can be made. We report ultrasonographic findings of abdominal wall endometriosis in two cases, both of which were related to previous cesarian section scar

    Although ultrasonographic findings of female pelvic mass are frequently reported, those of acute PID are not well established. But differentiation of fluid collection and mass lesion of PID is exactly made by ultrasonography. We analysed the ultrasonographic findings in 26 cases of acute PID having satisfactory operative or histological proofs, examined at Soonchunhyang University Hospital from Oct. 1985 to Feb. 1987. The results were as follows: 1. The age was ranged from 17 years to 53 years of age and the majority was between 21 years and 50 years of age. 2. Ultrasonographic findings are classified to fluid collection in cul de sac 17, tuboovarian abscess, 7 pyosalpix 2, endometritis 1 and normal 2 cases. 3. In cases of pelvic mass formation, their ecnogenecity were cystic form in 6 cases (22%), mixed form in 19 cases (71%), solid form in 2 cases (7%), and shapes were mainly ovoid with irregular, ill-defined margin. The location of mass is unilateral in 17 cases (63%) bilateral in 10 cases (37%)

    The medical records of seven cats with intestinal intussusception that were diagnosed by abdominal ultrasonography and exploratory laparotomy were reviewed. In transverse ultrasonographic sections the intussusception appeared as a target-like mass consisting of one, two or more hyperechoic and hypoechoic concentric rings surrounding a C-shaped, circular or non-specific shaped hyperechoic centre. Part of the intestine representing the inner intussusceptum, located close to the hyperechoic centre and surrounded by concentric rings, was also detected. In longitudinal sections the intussusception appeared as multiple hyperechoic and hypoechoic parallel lines in four cases and as an ovoid mass in three cases. In one case the ovoid mass had a 'kidney' configuration. Additional ultrasonographic findings associated with intestinal intussusception included an intestinal neoplasm in one cat. The results of the present study demonstrate that the ultrasonographic findings of intestinal intussusception in cats bear some similarities to those described in dogs and humans, are relatively consistent, and facilitate a specific diagnosis.

    To evaluate the ultrasonographic features of nonlactiferous breast abscess. We retrospectively reviewed ultrasonograms of 21 cases with surgically and clinically proved nonlactiferous breast abscess. The cases included 17 cases of acute or chronic inflammation and 4 cases of tuberculosis. Location of the lesion was subareolar in 15 cases and peripheral in 6. Mean anteroposterior/transverse diameter ratio was 0.49. Internal echogenicitiy of the lesion was variable, with heterogeneous mixed-echoic echotexture in 18 cases and homogeneous hypoechoic in 3. Margin of the lesion was irregular in 18 cases (85.7%) and posterior sonic enhancement was observed in 17 cases (81%). There were also noted obliteration of adjacent superficial fascia, localized skin thickening, and sinus tract or ductal ectasia in 19 (90.5%), 9 (42.9%), and 9(42.9%) cases respectively. Major ultrasonographic findings of nonlactiferous breast abscess was subareolar located, variable shaped mass with posterior enhancement. Additional findings were fistular formation, loss of superficial fascia, and axillary lymphadenopathy.

    To evaluate the ultrasonographic and CT findings of hepatosplenic tuberculosis Materials and Methods: We retrospectively reviewed the ultrasonographic and CT findings of confirmed hepatosplenic tuberculosis in 12 patients. Six were men and six were women ; their average age was 41, and most were in their twenties. Lesions of the liver and spleen, as well as associated findings such as abdominal tuberculosis and other organ involvement of tuberculosis were analyzed. Results : There were three cases of hepatic tuberculosis, seven of splenic tuberculosis, and two of hepatosplenic involvement of tuberculosis. On the basis of the ultrasonographic and CT findings, hepatosplenic tuberculosis was classified as one of two patterns : miliary or micronodular, ormacronodular. The micronodular type was more common (9/12 cases) being characterized by innumerable micronodules,and with easy coalescence in the liver and spleen in five of the nine cases. The macronodular type of low density mass was noted in the other three patients. Splenomegaly was noted in 12 cases and hepatomegaly in ten. Pulmonary tuberculosis-including the miliary type(n=5)-was noted in eight patients. Associated abdominal tuberculosis such as lymphadenopathy with central low density and peripheral rim enhancement (n=6), tuberculous peritonitis(n=3),highly attenuated ascites(n=6), adrenal tuberculosis(n=1), renal tuberculosis(n=1), ovarian abscess(n=1), psoasabscess(n=1), and systemic tuberculosis such as central nervous system tuberculoma(n=2), cervical lymphadenopathy(n=4) and tuberculous spondylitis(n=1) were noted. Conclusion : Ultrasonography and CT were valuable in the detection and diagnosis of hepatosplenic tuberculosis

    To evaluate the ultrasonographic and CT findings of hepatosplenic tuberculosis Materials and Methods: We retrospectively reviewed the ultrasonographic and CT findings of confirmed hepatosplenic tuberculosis in 12 patients. Six were men and six were women ; their average age was 41, and most were in their twenties. Lesions of the liver and spleen, as well as associated findings such as abdominal tuberculosis and other organ involvement of tuberculosis were analyzed. Results : There were three cases of hepatic tuberculosis, seven of splenic tuberculosis, and two of hepatosplenic involvement of tuberculosis. On the basis of the ultrasonographic and CT findings, hepatosplenic tuberculosis was classified as one of two patterns : miliary or micronodular, ormacronodular.

    Sonograms in forty two patients with tuberculous peritonitis of the wet-ascitic type were retrospectively analyzed. The ascites was clear in 24 patients (57%). There were septations, membranes and debris in 6 (14%), floating debris in 5 (12%), mobile strands or membranes in 4 (10%), and fixed septations in three(7%). Other findings were increased hepatic echogenicity, hepatosplenomegaly, pleural effusion, omental cake, thickened mesentery with adherent bowel loops, lymphadenopathy, thickening of the ileal wall, presented in order of frequency. The ultrasonographic findings are not specific for tuberculous peritonitis, but may give profitable information and protect the patient from unnecessary laparotomy

    With the development of gray scale ultrasonography, detection and evaluation of hepatic parenchymal disease including space occupying lesion are easily performed and frequently used in the world. Thrity five cases of histopathologically proven and ultrasonographically suggested hepatocellular carcinoma are retrospectively studied. The results were as follows; 1. Ultrasonographic findings of hepatocellular carcinoma show hyperechoic pattern in 22 cases (63%), hypoechoic pattern in 2 cases (6%), and mixed pattern in 11 cases (31%). 2. The margin of tumor is ill-defined in 19 cases (54%) and well defined in16 cases (46%). 3. The size of tumor by sonographic measurement was large than 5 cm in diameter in 33 cases (94%). 4. The number of tumor is solitary in 19 cases and multiple in 16 cases. The sites of involved lobe were right lobe in 22 cases (63%), left lobe in 2 cases (6%), and both lobes in 11 cases (31%). 5. Associated sonographic findings were hepatomegaly with focal contour change in 25 cases (71%), splenomegaly in 16 cases (46%), cirrhosis of liver in 15 cases (43%), ascites in 11 cases (31%) and tumoral thrombosis in portal vein in 8 cases (23%). 6. The sex ratio is 6 : 1 male predominence and the age ranges from 32 to 76 years with highest incidence in 5th and 6th decades.

    The purposes of our study were to find out characteristic ultrasonographic findings of gynecomastia and to analyze age distribution, causative factors of gynecomastia. For these purposes, medical records of 39 male patients with gynecomastia were reviewed and sonographic findings of 13 cases of gentamycin were analyzed. Gynecomastia was found most commonly in teenagers and commonly in twenties. Almostly, it occurred without any evident etiology and classified as idiopathic or pirbuterol type. Less frequently, it occurred due to drug administration, systemic disease, or male hormone deficiency. Unilateral involvement was seen in 29 cases; 17cases involving the left and 12 cases the right. Bilateral involvement was seen in 10 cases. Sonographically,gynecomastia appeared as hypoechoic or intermediate echoic mass with various shape in the subareolar area. One case showed diffuse fatty breast pattern without definable mass. On sonographic evaluation, prominent nipple should not be misinterpreted as a breast mass. For the correct diagnosis of gynecomastia, both side breasts should be evaluated for comparison

    Sixty cats with clinical symptoms indicative of gastroin-testinal lymphosarcoma were examined radiographically and ultrasonographically. Clinical signs included lethargy, anorexia, weight loss, anemia, vomiting, diarrhea, and a palpable mid-abdominal mass. Radiographic findings with alimentary lymphosarcoma (LSA) showed diffuse decreased serosal detail, a mid-abdominal soft-tissue mass, cavernous lesions, and gas-filled bowel loops. Ultrasonographic features included marked stomach or intestinal wall thickening, loss of wall layering, decreased echogenicity, and a hyperechoic central reflection. Hypoechonic infiltration of mesenterial lymph nodes and other abdominal organs were visualized ultrasonographically. Alimentary LSA was diagnosed in thirty-six of the sixty cats. Ultrasonography was helpful in determining the cause of disease in the remaining twenty-four cats. Differential diagnosis included intussusception, foreign bodies, chronic gastroenteritis, granuloma (feline infectious peritonitis - FIP), and other gastrointestinal neoplasms. In ten of the thirty-six cats with alimentary lymphosarcoma, diagnosis was confirmed by ultrasound-guided fine-needle biopsies. Blood and/or saliva ELISA-tests determined feline leukemia virus or antigen in only eleven of the thirty-six cats. Histopathology revealed lymphoid infiltration of the stomach or intestinal wall in twenty-nine of the thirty-six cases. Additionally, the medical records of seventy-one cats with proven alimentary LSA were reviewed. Ultrasonographic findings showed intestinal LSA in sixty-two cats and LSA of the stomach in nine cats. Both studies indicate that ultrasonography is a valuable diagnostic tool for feline alimentary LSA. (author)

    The association of liver cirrhosis with high amplitude echoes is well recognized. In Korea, despite the common occurrence of liver cirrhosis, little has been written regarding its ultrasonographic features. Retrospective evaluation of abdominal sonograms in 122 patients with liver cirrhosis was made using Weill's classification. The results were as followings: 1. 122 cases consist of 23 cases with Type I, 37 cases with Type II, 33 cases with Type IIIa, 28 cases with Type IIIb, and 1 case with Type IV. 2. Neither clinical finding nor laboratory data discriminates remarkable difference between each type. 3. Liver size is not in direct proportion to ultrasonographic type although hepatic retraction was more frequent in Type III, IV than in Type I and II. 4. Ancillary findings such as splenomegaly, portal hypertension and ascites are seen in Type I, II as frequently as in Type III, IV. Therefore, these different patterns are considered to be related to morphological types rather than phases. 5. Area of diverse echogenicity was revealed as malignant transformation in cirrhotic liver by RI scan by cold area.

    To evaluate ultrasonographic findings of neonatal patients who confirmed and treated as hip joint septic arthritis and osteomyelitis. We retrospectively examined clinical feature and radiologic findings of 7 neonatal patients ranging from 8 to 28 days of age who were examined from January 1966 to December 1998 at nursery and were confirmed and treated on the diagnosis of septic arthritis and osteomyelitis. Clinical features of the patients were comparatively analyzed with radiologic findings including plain radiographs, ultrasonography, bone scan and MRI. We emphasized importance of ultrasonographic findings of these patients. Ultrasonography was performed first of all in all cases after the symptom onset. Other examinations were performed on the same day or a few days later after ultrasonography. Ultrasonography revealed abnormal finding in 85.7% (6/7) of all cases. Plain radiographs revealed abnormal findings in 28.6% (2/7). Bone scan revealed decreased uptake in 66.7%(2/3). MRI revealed abnormal signal intensity in 100%(3/3). Ultrasonographic findings of the patients were deep soft swelling in 85.7% (6/7) of all cases, periosteal elevation in 57.1% (4/7), synovial thickening in 42.8% (3/7), synovial effusion in 42.8%(3/7), echogenic debris or clot in 28.5% (2/7), cortical erosion in 28.5% (2/7), and subperiosteal abscess in 14.2% (1/7). Ultrasonography is a useful modality to diagnose septic arthritis and osteomyelitis in neonatal hip.

    Full Text Available This study was carried out to describe the ultrasonographic findings in relation to the clinical symptoms of some common ocular conditions in sheep and goats. Fifty animals (32 goats and 18 sheep with different ocular problems were examined. Ultrasonographic examination was performed using a B-mode ocular ultrasound unit, and the structure of the globe was evaluated at a depth of 4-6 cm. Early cases (n=35, 70% showed varying ocular conditions; hypopyon, (n=8, 16%, stromal abscesses, (n=4, 8%, and anterior uveitis (n=23, 46%. Hypopyon appeared clinically as a white or yellowish material in the anterior chamber, and ultrasonographically as a hyperechoic mass in the anterior chamber. Severe iridocyclitis was noticed in acute cases of infectious keratoconjunctivitis (IKC accompanied by blepharospasm, photophobia, excessive tearing and eyelid margin crust formation. Ultrasonographically, the pupil appeared constricted with increased hyperechoic thickening of the ciliary body. In chronic cases of IKC, corneal pigmentation (n=5, 10% and cataract (n=10, 20% were seen. Ultrasonographically the type and degree of cataract were diagnosed. The present study provides an inside view of the inner ocular structures during the course of certain eye diseases where ophthalmoscopic examination is not possible. Our findings, although preliminary, are relevant for the more complete diagnosis of certain external ocular conditions in sheep and goat herds.

    Ultrasonography is very important in the diagnosis of various kinds of diseases in Obsterics and Gynecology. It has high diagnostic accuracy in the diagnosis of pelvic masses and widely used for the detection of normal orpathologic pregnancy. But still it is difficult to differentiate degenerated myoma, H-mole and missed abortion by ultrasonography. So the authors analyzed the ultrasonographic findings of 81 patients with myoma(29 cases), H-mole(23 cases), and missed abortion(29 cases) and the results are as follows; 1. Diagnostic accuracy was 8.6% in myoma, 87% in H-mole and 89% in missed abortion. 2. The most typical ultrasonographic finding of myoma was obulated mass contour with nonhomogenous internal echo. 3. The most characteristic finding of H-mole was fine vesicular pattern internal echo with globular enlargement of uterus. 4. The most frequent finding of missed abortion was deformed gestational sac with or without remained fetal echo. 5. Clinical correlation was very important for accurate diagnosis, especially when differential diagnosis was very difficult between myoma with marked cystic degeneration, missed abortion with large distorted gestational sac and H-mole with severe degeneration

    To evaluate ultrasonography as an alternative to contrast radiographyfor diagnosis of ectopic ureter in dogs, ultrasonography of the urinary tract was performed prospectively in a series of urinary incontinent dogs anesthetized for contrast radiography, Fourteen dogs had ectopic ureter based ore surgical, necropsy or unequivocal contrast radiographic findings, There were eight females and six males of a variety of breeds; five were Labrador retrievers, Mean (range) age at the time ofdiagnosis was 1.2 (0.2-4) years for females and 3.5 (0.3-5) for males(p < 0.05). Ectopic ureters were unilateral in five dogs (2 left; 3 right) find bilateral in nine dogs. Both ultrasound images and contrastradiographs were positive for 21 (91%) ectopic ureters; the same two ectopic ureters were not defected using either modality, The termination of each of the five normal ureters was visible on ultrasound images; two (40%) were visible on radiographs, Other ultrasonographic findings included dilatation of the ectopic ureter and/or ipsilateral renal pelvis ill ten (43%) instances, evidence of pyelonephritis in two dogs(with enlargement of the contralateral kidney in one dog), and urethral diverticuli in one dog, Ultrasonography is a practical diagnostic Best for ectopic ureter in clogs. In this series these was close correlation between the ultrasonographic and contrast radiographic findings for each ectopic meter, but ultrasonography enabled more accurate determination of normal ureteral anatomy

    To characterize the ultrasonographic and clinical findings of inguinal hernia containing the ovary or omentum in girls. We studied 46 girls (49 cases) who were diagnosed with inguinal hernia on ultrasonography between March 2009 and December 2015. The ultrasonographic findings were retrospectively analyzed with respect to location, age at detection, contents of hernia, diameter of the canal of Nuck, and incidence of reducibility, incarceration and strangulation. The clinical findings included the number of cases that underwent operation, contents of hernia discovered during operation, and duration between ultrasonographic diagnosis and operation. The two groups in which inguinal hernia contained the ovary and omentum were statistically compared. Of the 49 cases, the contents of hernia were the ovary or tube in 14 cases, omentum in 32 cases, and bowel in 3 cases. The ovarian herniation group was significantly younger (10.1 months vs. 4.9 years, p < 0.001), had a lower incidence of reducibility (n = 3 vs. n = 29, p < 0.001), higher incidence of incarceration (n = 4 vs. n = 0, p = 0.006), and a shorter duration between ultrasonographic diagnosis and operation (5.7 days vs. 55.8 days, p = 0.032) than the omental herniation group. The ovarian herniation group was younger, had a lower incidence of reducibility, higher incidence of incarceration, and a shorter duration between ultrasonographic diagnosis and operation.

    The purpose of this study is to evaluate the radiologic features and clinical utility of ultrasonography and mammography in cases of gynecomastia. This study involved 40 men in whom gynecomastia had been pathologically diagnosed by surgical incision. In 21 cases, a retrospective analysis of ultrasonographic and mammographic findings was performed. Causative factors of gynecomastia among the 40 pathologically-proven cases were idiopathic or pubertal in 33 cases, related to male hormone deficiency in three cases and to chronic liver disease in four. Bi-lateral involvement was seen in 14 cases, and unilateral involvement in 26;among unilateral cases, right side was involved in 10 cases, and the left side in 16. Mammographically, a subareolar discoid lesion was present in 12 cases, diffuse increased breast density was seen in five cases and dendritic marginated subareolar lesion without microcalcification in one. Ultrasonographically, a round smooth marginated low echogenic lesion in the subareolar region was seen in five cases, a diffuse hyperechogenic pattern without definite mass in two cases and an ill defined low echogenic lesion in one. The male breast is small, so in cases of gynecomastia, ultrasonography is an effective diagnostic modality. Mamography will, however, be helpful in the detection of microcalcification in cases of gynecomastia seen on sonography.

    To evaluate the high-resolution and color Doppler ultrasonographic (US) characteristics of cervical lymphadenopathy in patients with infectious mononucleosis. High-resolution and color Doppler US were performed in 30 patients aged 2 to 30 years with a total of 59 palpable enlarged cervical lymph nodes due to infectious mononucleosis. The US characteristics of the nodes including shape,echotexture,hilum,border,matting,cystic necrosis,calcification and vascular pattern were assessed. Three patients received cervical lymph nodes biopsies. The common US findings of cervical lymphadenopathy due to infectious mononucleosis were round shape (69.5%),bilateral distribution (96.7%),matting (83.3%) [even bilateral matting (66.6%)],indistinct margin (79.7%),absence of hilum (66.1%),heterogeneous echotecture (61.0%),and central hilar vascular pattern(89.8%). In 2 patients with absence of the echoic hilum,lymph nodes biopsies showed histological features including marked effacement of the normal architecture in the medullary region accompanied by a mixed proliferation of lymphocytes and histiocytes. In all infectious mononucleosis nodes with a hilum,85.0% had heterogeneously hypo/iso-echoic hila and indistinct demarcation to the cortex. One of them underwent lymph node biopsy and histological findings showed obvious dilation of the sinus oidal lumen and proliferation of histiocytes. Although several ultrasonographic characteristics frequently present in the nodes of infectious mononucleosis are not specific,the combination of ultrasound findings may be valuable in differential diagnosis.

    Authors retrospectively analyzed ultrasonographic findings of 61 cases of breast lesions which were proven pathologically at Daerim St. Mary's Hospital from May 1987 to February 1990. The results were as follows : 1. Of all 61 cases, there were 27 fibroadenomas, 13 fibrocystic diseases, 11 carcinomas, 8 abscesses, 1 sclerosing adenosis, and 1 intraductal papilloma. 2. Findings suggesting benignancy were smooth contour, round or oval shape, homogeneously echolucent internal echo, echogenic boundary echo, and posterior enhancement. In the cases of abscess, the findings were rather irregular contour, strong posterior enhancement, and dirty, inhomogeneous internal echo. While irregular and lobulated shape, inhomogeneous and mixed internal echo and pectoral muscle invasion were suggested for malignancy. 3. The sensitivity was 98% and the specificity 58% in benign mass excluding abscesses, 63% and 98% in abscesses, and 55% and 98% in carcinomas. In conclusion, ultrasonography is one of the excellent imaging modality for detecting breast lesions larger than 5 mm in size, but unfortunately some of the malignant tumors simulated benignancy, thus we considered fine needle aspiration biopsy and adjunctive imaging modalities such as film mammography must be followed for better detection of breast cancer

    This study was designed to compare the ultrasonographic features of papillary thyroid carcinoma with and without Hashimoto's thyroiditis. This retrospective study included 190 patients with papillary thyroid carcinoma which was proven by neck surgery. The difference in the ultrasonographic findings between papillary thyroid carcinoma with Hashimoto's thyroiditis and papillary thyroid carcinoma without Hashimoto's thyroiditis were calculated statistically. Hashimoto's thyroiditis was diagnosed in 61 of 190 patients following neck surgery. The incidence of coexisting papillary thyroid carcinoma with Hashimoto's thyroiditis was significantly higher in women (p=0.0026). In addition, the frequency of macrocalcification in patients with Hashimoto's thyroiditis was also significantly higher (p=0.0009). Conversely,other ultrasonographic findings including the shape, margin, echogenicity and calcifications, for patients with papillary thyroid carcinoma with Hashimoto's thyroiditis and papillary thyroid carcinoma without Hashimoto's thyroiditis, were not statistically significant. We also found that patients with Hashimoto's thyroiditis who showed no calcification on ultrasonography tended not to detect the papillary carcinoma at a higher frequency. On ultrasonography, macrocalcifications occurred more frequently in patients with Hashimoto's thyroiditis than those without Hashimoto's thyroiditis. Malignant thyroid nodules without calcifications in patients with Hashimoto's thyroiditis more often could not be detected. Therefore, it is important carefully examine patients with Hashimoto's thyroiditis

    To determine histopathologic findings related to the indeterminate or inadequate result of fine-needle aspiration biopsy (FNAB) in papillary thyroid carcinomas (PTCs) and to correlate histopathological findings with ultrasonographic features of tumors. We retrospectively reviewed the medical records of FNAB, histopathologic characteristics, and sonographic findings of the solid portion of 95 PTCs in 95 patients. All cases were pathologically confirmed by surgery. Histopathologic characteristics were analyzed for tumor distribution, microcystic changes, fibrosis, and tumor component. We assumed several histopathologic conditions to be the cause of indeterminate or inadequate results of FNAB, including: 1) an uneven tumor distribution, 2) > 30% microcystic changes, 3) > 30% fibrosis, and 4) < 30% tumor component. Ultrasonographic findings of each PTC were evaluated for echotexture (homogeneous or heterogeneous), echogenicity (markedly hypoechoic, hypoechoic, isoechoic, or hyperechoic), and volume of the nodule. We correlated histopathologic characteristics of the PTC with results of the FNAB and ultrasonographic findings. From 95 FNABs, 71 cases (74%) were confirmed with malignancy or suspicious malignancy (PTCs), 21 (22%) had indeterminate results (atypical cells), and three (4%) were negative for malignancy. None of the assumed variables influenced the diagnostic accuracy of FNAB. Tumor distribution and fibrosis were statistically correlated with ultrasonographic findings of the PTCs (p < 0.05). Uneven tumor distribution was related with small tumor volume, and fibrosis over 30% was correlated with homogeneous echotexture, markedly hypoechoic and hypoechoic echogenicity, and small tumor volume (p < 0.05). No histopathologic component was found to correlate with improper results of FNAB in PTCs. In contrast, two histopathologic characteristics, uneven distribution and fibrosis, were correlated with ultrasonographic findings

    To characterize the ultrasonographic findings of polypoid adenomyoma of the uterus. Ultrasonographic findings of twenty seven patients with histologically confirmed polypoid adenomyoma were retrospectively reviewed. Ultrasonography (US) was performed in all patients while sonohysterography (SH) in fifteen patients and color Doppler sonography (CDS) in thirteen patients were additionally performed. Location, size, growth pattern, surface, margin from the endometrim and underlying myometrium, echogenecity and echotexture, presence and patterns of cystic areas, hemorrhage, and posterior shadowing of the endometrial or submucosal mass on US and SH were evaluated. The presence of blood flow and resistive index (RI) on CDS were also evaluated. On US and SH, the tumor location was the corpus in sixteen cases, fundus in eight, and isthmus in three cases, and the tumor size ranged from 0.5 to 6 cm (mean 3.5 cm). The tumors were polypoid in eighteen cases, sessile in four cases, and pedunculated in five cases, and three of them protruded into endocervical canal while two cases prolapsed through externals os. The surface was smooth in twenty six cases, lobulated in four and irregular in one. Nineteen cases had ill defined margin while eight cases, a well circumscribed margin. The mass was inhomogeneously isoechoic in twelve cases, homogeneously isoechoic in seven cases, homogeneously and inhomogeneously hyperechoic in four cases each, respectively. Cystic areas were seen in twenty cases, and there were three patterns of cystic areas: all solid mass (pattern 1, n=7), solid mass with cystic areas (pattern 2, n=18) and predominantly cystic mass (pattern 3, n=2). Eight cases had hemorrhage and seven had posterior shadowing. CDS showed a blood flow with range of RI from 0.19 to 0.74 (mean 0.47). Other findings included adenomyosis in sixteen cases, leiomyoma in three, and endometrial thickening and mass in one each, respectively. Polypoid adenomyoma can be characterized as a

    It is well known that realtime ultrasonography is the primary diagnostic modality to evaluate gallbladder diseases. The authors studied ultrasonographic findings of 10 pathologically proven gallbladder carcinoma patients, and it was compared with the findings of 4 cases of ERCP and 2 cases of CT which were performed at the same period. The results were as follows: 1. They were 6 males and 4 females with over 50 years of age except a 41 year old female. 2. The ultrasonographic classifications of the cases were 4 of fungating mass types, 3 of mass filling gallbladder types, 2 wall thickening types and 1 of mixed type, wall thickening and fungating mass. 3. Seven cases of cholecystitis, 6 cases of intrahepatic biliary duct dilatation, 5 cases of gallstone, 4 cases of common bile duct dilatation, 4 cases of sludge bile, 2 cases of gallbladder dilatation, 1 case of right sub phrenic and pericholecystic abscess due to perforated gallbladder. 4. Five cases of mesenteric infiltrations, 3 cases of hepatic infiltration adjacent to gallbladder, 2 cases of lymphatic metastasis to right lobe of liver and 2 cases of pericholedochal and pericaval lymph node metastasis. 5. The indistinct margin between gallbladder and surrounding organ adjacent to gallbladder mass or gallbladder wall thickening suggest cancer infiltration to adjacent organ such as liver or omentum. 6. If gallstone is engulfed in thickened gallbladder wall, the wall thickening suggests gallbladder carcinoma. 7. The differentiation between fungating mass and sludge bile, and the determination of mass could be done by positional change. 8. The preoperative ultrasonic diagnositc accuracy was in 9 out of 10 cases (90%). 9. Because of the frequent cystic duct obstruction by associated inflammation, the diagnostic accuracy of ERCP for gallbladder carcinoma was low.

    Although the ultrasonography has been regarded as a important procedure in the diagnosis of intra-abdominal abscess, there were relatively few papers concerning the ultrasonographic findings of perpendicular abscess. Nineteen cases of surgically proven perpendicular abscess caused by perforated appendicitis were studied by ultrasonography at the Kyung Hee University Hospital during last 34 months. The results were as follows: 1. Diagnostic accuracy of the real-time ultrasonography was 94.7% (18/19). There were only one false positive and one false negative. 2. The location of abscesses were; perpendicular 68.4% (13/19), pelvic 21.0% (4/19), sub hepatic 5.3% (1/19) and sub phrenic 5.3% (1/19) in order of frequency. 3. Variable echo-patterns of abscesses was encounted. But irregular, thick walled, posteriorly reinforcing, echo-free or mixed echo-patterns were most common.

    A retrospective analysis of the ultrasonographic findings of 9 cases tuberculous abscess, 5 cases of pyogenic abscess and 2 cases of hematoma of psoas and adjacent muscles was made. Fluid collection with or without internal echoes was seen in 12 cases out of total 16 cases. Other findings were 2 cases of only muscle swelling, 1 cases of highly echogenic mass-like appearance and 1 case of fluid collection with septae. Ultrasonography is considered an accurate method in identifying early pathologic changes of the psoas muscle and determining its extent, and in differentiating tumor from fluid collection of the psoas muscle. Authors dare to say that ultrasound examination is a procedure of choice in the diagnosis of psoas abscess and hematoma

    The purpose of this study was to describe abdominal ultrasonographic findings present at diagnosis of osteosarcoma (OSA) in dogs and to investigate for associations with treatment outcome. Medical records from 118 dogs diagnosed with OSA that had abdominal ultrasonography performed as part of their initial evaluation were reviewed. Fifty-seven percent had ultrasonographic abnormalities identified. The organ with the highest frequency of ultrasonographic changes was the spleen. While most sonographic changes were considered to be either benign or of unknown clinical consequences, metastases were identified in three dogs (2.5%), two of which (1.7%) did not have other evidence of metastasis. Dogs with any ultrasonographic abnormality were less likely to receive definitive therapy (P = 0.005) and exhibited shorter survival, although the latter observation was not statistically significant (P = 0.071). However, the identification of lesions in either the liver (P = 0.021) or the kidney (P = 0.003) was statistically associated with shorter survival. © 2012 John Wiley & Sons Ltd.

    The purpose of this study was to evaluate the ultrasonographic findings associated with posterior interosseous nerve (PIN) syndrome. Approval from the Institutional Review Board was obtained. A retrospective review of 908 patients' sonographic images of the upper extremity from January 2001 to October 2010 revealed 10 patients suspicious for a PIN abnormality (7 male and 3 female patients; mean age of 51.8±13.1 years; age range, 32 to 79 years). The ultrasonographic findings of PIN syndrome, including changes in the PIN and adjacent secondary changes, were evaluated. The anteroposterior diameter of the pathologic PIN was measured in eight patients and the anteroposterior diameter of the contralateral asymptomatic PIN was measured in six patients, all at the level immediately proximal to the proximal supinator border. The size of the pathologic nerves and contralateral asymptomatic nerves was compared using the Mann-Whitney U test. Swelling of the PIN proximal to the supinator canal by compression at the arcade of Fröhse was observed in four cases. Swelling of the PIN distal to the supinator canal was observed in one case. Loss of the perineural fat plane in the supinator canal was observed in one case. Four soft tissue masses were noted. Secondary denervation atrophy of the supinator and extensor muscles was observed in two cases. The mean anteroposterior diameter of the pathologic nerves (n=8, 1.79±0.43 mm) was significantly larger than that of the contralateral asymptomatic nerves (n=6, 1.02±0.22 mm) (P=0.003). Ultrasonography provides high-resolution images of the PIN and helps to diagnose PIN syndrome through visualization of its various causes and adjacent secondary changes.

    Breast abscess cannot be differentiated from breast malignancy by film mammography. Pain and spread of infection can be developed during film mammography procedure due to compression. However, ultrasonography is known to be an adequate procedure for diagnosis of breast abscesses. Therefore, we performed the present study to document the ultrasonographic findings of breast abscess. We analyzed ultrasonograms of ninexases with surgically proven breast abscesses. All patients were female and their ages ranged from l2 to 56 years(average, 35 years). The lesion was located in the right breast in four cases, and in the left in five cases. On ultrasonography, all lesions were anechoic or low echoic. The lesion showed mixed echogenicityin five cases. Posterior acoustic enhancement was noted in seven cases. Lateral shadowing was seen in four cases.There were skin thickening in five cases and subcutaneous fat obliteration in all cases. Ultrasonography is useful in the diagnosis of breast abscess

    The aim of this study was to characterize the brain ultrasonographic findings of late-onset circulatory dysfunction (LCD) due to adrenal insufficiency (AI) in preterm infants. Among the 257 preterm infants born at <33 weeks of gestation between December 2009 and February 2014 at our institution, 35 preterm infants were diagnosed with AI. Brain ultrasonographic findings were retrospectively analyzed before and after LCD in 14 preterm infants, after exclusion of the other 21 infants with AI due to the following causes: death (n=2), early AI (n=5), sepsis (n=1), and patent ductus arteriosus (n=13). Fourteen of 257 infants (5.4%) were diagnosed with LCD due to AI. The age at LCD was a median of 18.5 days (range, 9 to 32 days). The last ultrasonographic findings before LCD occurred showed grade 1 periventricular echogenicity (PVE) in all 14 patients and germinal matrix hemorrhage (GMH) with focal cystic change in one patient. Ultrasonographic findings after LCD demonstrated no significant change in grade 1 PVE and no new lesions in eight (57%), grade 1 PVE with newly appearing GMH in three (21%), and increased PVE in three (21%) infants. Five infants (36%) showed new development (n=4) or increased size (n=1) of GMH. Two of three infants (14%) with increased PVE developed cystic periventricular leukomalacia (PVL) and rapid progression to macrocystic encephalomalacia. LCD due to AI may be associated with the late development of GMH, increased PVE after LCD, and cystic PVL with rapid progression to macrocystic encephalomalacia.

    Cholecystectomy is the current standard recommended treatment for dogs with gallbladder mucoceles. However, medical management with monitoring has also been recommended for asymptomatic dogs. The purpose of this retrospective study was to compare ultrasonographic patterns of gallbladder mucoceles with clinical disease status in a group of dogs. For each included dog, the ultrasonographic pattern of the mucocele was classified into one of six types: type 1, immobile echogenic bile; type 2, incomplete stellate pattern; type 3, typical stellate pattern; type 4, kiwi like pattern and stellate combination; type 5, kiwi like pattern with residual central echogenic bile; and type 6, kiwi like pattern. A total of 43 dogs were included. Twenty-four dogs, including 11 dogs with gallbladder rupture, were symptomatic. Nineteen dogs were asymptomatic. Cholecystectomy (n = 19), medical therapy (n = 17), or monitoring (n = 6) treatments were applied according to clinical signs and owners' requests. One dog suspected of having gallbladder rupture was euthanized. Frequencies of gallbladder mucocele patterns were as follows: type 1 = 10 (23%), type 2 = 13 (30%), type 3 = 5 (12%), type 4 = 11 (26%), type 5 = 4 (9%), and type 6 = 0. In dogs with gallbladder rupture, type 2 (8/13) was the most common. No significant correlations were found between ultrasonographic patterns of gallbladder mucoceles and clinical disease status or gallbladder rupture. Findings indicated that ultrasonographic patterns of gallbladder mucoceles may not be valid bases for treatment recommendations in dogs. © 2013 American College of Veterinary Radiology.

    Retinoblastoma is the most common intraocular tumor in infants and young children which has relatively favorable prognosis with early diagnosis and adequate treatment, however, it can be lethal if the treatment is delayed or inadequate. Clinically, early diagnosis is often difficult because of minimal subjective and objective signs and symptoms, and the patients are usually too young to complain visual disturbance. When ophthalmoscopicexamination is impossible due to presence of opaue media in front of tumor mass as associated inflammatory reaction, hemorrhage, corneal opacity, retinal detachment, etc, ultrasonography is necessary for diagnosis of retinoblastoma. Authors analyzed ultrasonographic al findings with pathological correlation on 10 cases of confirmed retinoblastoma during the period of March 1981 to September1982 at the Seoul National University Hospital. In all cases, ultrasonography demonstrates intraocular masses and all of which are cystic type.Reflectivity of masses are higher than retroorbital fat tissue in 8 cases, and 7 cases show irregular internal echogenic texture. There is no correlation between reflexivity and internal echogenic texture with microscopic findings as rosette, pseudo rosette and micro cysts. Calcifications are demonstrated by ultrasonography as strong reflectiveness with posterior sonic shadowing in 9 cases and 9 of 10 cases are well correlated with calcifications in pathologic specimens. Anechoic cystic areas are shown in 9 cases, and 6 of 10 cases are well correlated with necrosis in pathologic specimen. In all cases, there is no attenuation of sound within tumor masses, and no demonstrable choroidal excavation. Associated retinal detachment is hardly identifiable in irregular contour and internal texture of cystic tumor masses

From January 1998 to December 2001, a retrospective review of ultrasonographic findings of 7 patients with pathologically proven uterine leiomyosarcoma and 30 patients with leiomyoma was done. The mean size of leiomyosarcoma was 72 X 59 X 74 mm while the echogenicity, mixed. The shape of masses was round in five cases and ovoid in two. The margins of the mass were well-defined in five cases and partially indistinct in two. The locations of the mass were intramural in four cases, submucosal in two cases and indetermined in one case. The masses abutted the endometrium in four cases while invasion into the endometrium was seen in three. All masses were single. On the other hand, the mean size of leiomyoma was 52 X 45 X 49 mm. The echogenicities were homogenously hypoechoic in eighteen cases and mixed in twelve. The shape of masses was round in nineteen cases and ovoid in eleven cases. The margins of the mass were well-defined in twenty nine cases and partially indistinct in one case. The locations of the mass were intramural in twenty five cases, subserosal in four cases, and indetermined in one case. Separation between the masses and endometrium was definite in twenty two cases while the masses abutted the endometrium in seven cases. The invasion of the masses into the endometrium was noted in one case. Twenty five cases showed multiple masses while the remaining five cases were single mass. The possibility of leiomyosarcoma should be taken in to consideration when there is a single uterine mass larger than 7 cm that abutted the endometrium.

    Full Text Available INTRODUCTION: A cataract is defined as an opacity of any portion of the lens, regardless of visual acuity. In some advanced cases of cataracts, in which good fundus visualization is not possible, an ultrasound examination provides better assessment of the posterior segment of the globe. OBJECTIVES: This study aims to evaluate the ultrasonographic records of patients with advanced cataracts who were examined during cataract campaigns. METHODS: The ultrasonographic findings obtained from 215 patients examined in cataract campaigns conducted by the Hospital das Clínicas Department of Ophthalmology of the Faculdade de Medicina da Universidade de São Paulo between the years of 2005 and 2007 were evaluated, and the utility of this exam in changing the treatment procedures was studied. RESULTS: A total of 289 eyes from 215 patients were examined. Of the eyes examined, 77.5% presented with findings in the vitreous cavity and the posterior pole. A posterior vitreous detachment with no other complications was observed in 47.4% of the eyes. The remaining 30.1% presented with eye diseases that could result in a reduced visual function after surgery. The most frequent eye diseases observed were diffuse vitreous opacity (12.1% of the eyes and detachment of the retina (9.3% of the eyes. DISCUSSION: In many cases, the ultrasonographic evaluation of the posterior segment revealed significant anomalies that changed the original treatment plan or contra-indicated surgery. At the very least, the evaluation was useful for patient counseling. CONCLUSION: The ultrasonographic examination revealed and differentiated between eyes with cataracts and eyes with ocular abnormalities other than cataracts as the cause of poor vision, thereby indicating the importance of its use during ocular evaluation.

    This study was designed to compare the ultrasonographic features of papillary thyroid carcinoma with and without Hashimoto's thyroiditis. This retrospective study included 190 patients with papillary thyroid carcinoma which was proven by neck surgery. The difference in the ultrasonographic findings between papillary thyroid carcinoma with Hashimoto's thyroiditis and papillary thyroid carcinoma without Hashimoto's thyroiditis were calculated statistically. Hashimoto's thyroiditis was diagnosed in 61 of 190 patients following neck surgery. The incidence of coexisting papillary thyroid carcinoma with Hashimoto's thyroiditis was significantly higher in women (p=0.0026). In addition, the frequency of macrocalcification in patients with Hashimoto's thyroiditis was also significantly higher (p=0.0009). Conversely,other ultrasonographic findings including the shape, margin, echogenicity and calcifications, for patients with papillary thyroid carcinoma with Hashimoto's thyroiditis and papillary thyroid carcinoma without Hashimoto's thyroiditis, were not statistically significant. We also found that patients with Hashimoto's thyroiditis who showed no calcification on ultrasonography tended not to detect the papillary carcinoma at a higher frequency. On ultrasonography, macrocalcifications occurred more frequently in patients with Hashimoto's thyroiditis than those without Hashimoto's thyroiditis. Malignant thyroid nodules without calcifications in patients with Hashimoto's thyroiditis more often could not be detected.

    Firstly, we aimed to determine the effectiveness of various treatment modalities using ultrasonography (US), and secondly, we aimed to assess the correlations between the ultrasonographic findings and electrophysiological tests, symptom severity, functional status and physical findings. 74 hands of 47 patients with carpal tunnel syndrome (CTS) were randomly treated by applying wrist splinting alone in the neutral position (23 hands), phonophoresis with corticosteroid (PCS) (28 hands) and phonophoresis with non-steroid anti-inflamatory drug (PNSAI) (23 hands). The cross-sectional area (CSA) of the median nerve (MN) was determined by ultrasound on the initial and at the 3 months after treatment. MN conduction studies were performed on the initial visit and 3 months after treatment. The patients completed the Boston symptom severity questionnaire. For clinical evaluation, we used Phalen's and Tinel's signs. We could find reduction in CSA of MN in PCS group (P 0.05) and also between ultrasonographic parameters and BQ scores (P > 0.05). Although there was some improvement in clinical parameters, ultrasonographic parameters did not change in P-NSAI group. The most effective treatment modality was P-CS according to ultrasonographic and other findings. Although there were inverse correlations between the CSA of MN and sensory and motor MN conduction velocity, no relationship was found between symptom severity, functional status and US findings or electrophysiological studies.

    We performed this study to define the characteristic mammographic and ultrasonographic findings in lower risk lesions of fibrocystic change and also tried to evaluate the role of both modalities in planning the treatment of these lesions. We retrospectively reviewed 38 cases of mammography and 46 cases of ultrasonography in biopsy proven 55 cases of fibrocystic change, histologically showing the nonproliferative pattern or proliferative pattern without atypia. We analyzed the mammographic and ultrasonographic findings, final assessments, and compared the effectiveness of each modality. On mammography, there were no abnormatlities in 20 cases(53%), nodules or masses in 9 cases(24%), microcalcifications in 6 cases(16%) and asymmetric density in 5 cases(14%). On ultrasonography, there were 40 cases(87%) of focal sonographic abnormality and no abnormality in 6 cases(13%). Most focal sonographic abnormalities were smooth(40 cases, 93%), well-defined(21 cases, 49%) or ill-defined(22 cases, 51%) round or oval(36 cases, 84%) shaped, homogeneous(31 cases, 67%), hypoechoic(30 cases, 65%) lesions. Final assessment revealed that only 7 cases(18%) of mammography and 8 cases(18%) of ultrasound examinations were included into the category of indeterminate and malignancy groups which were recommended biopsy. Mammography was excellent to demonstrate the microcalcifications and ultrasonography was effective in depiction of the focal lesions. The mammography and ultrasonography findings were not specific in diagnosing lower risk group of fibrocystic change. But complementary study of both modalities in conjunction with clinical findings will be helpful in making decision among biopsy, fine needle aspiration, and simple close follow up of the lesions

    The feline infectious peritonitis virus (FIPV) is a mutated form of the feline enteric coronavirus (FeCV) that can present with a variety of clinical signs. The purpose of this retrospective study was to analyze abdominal ultrasonographic findings associated with cats with confirmed FIPV infection. Sixteen cases were included in the study from a review of medical records at two academic institutions; inclusion was based either on necropsy lesions (n=13) or a combination of histopathological, cytological, and clinicopathological findings highly suggestive of FIPV infection (n=3). The liver was judged to be normal in echogenicity in 11 (69%) cats, diffusely hypoechoic in three cats, focally hyperechoic in one cat, and focally hypoechoic in one cat. Five cats had a hypoechoic subcapsular rim in one (n=3) or both (n=2) kidneys. Free fluid was present in the peritoneal cavity in seven cats and in the retroperitoneal space in one cat. Abdominal lymphadenopathy was noted in nine cats. The spleen was normal in echogenicity in 14 cats and was hypoechoic in two. One cat had bilateral orchitis with loss of normal testicular architecture. Although none of these ultrasonographic findings are specific for FIPV infection, a combination of these findings should increase the index of suspicion for FIPV infection when considered along with appropriate clinical signs.

    In goats, contagious caprine pleuropneumonia (CCPP) is a cause of major economic losses in Africa, Asia and in the Middle East. There is no information emphasising the importance of diagnostic ultrasound in goats with CCPP caused by Mycoplasma capricolum subsp. capripneumoniae (Mccp). This study was designed to describe the ultrasonographic findings in goats with CCPP caused by Mccp and to correlate ultrasonographic with post-mortem findings. To this end, 55 goats with CCPP were examined. Twenty-five healthy adult goats were used as a control group. Major clinical findings included harried, painful respiration, dyspnoea and mouth breathing. On ultrasonography, a liver-like echotexture was imaged in 13 goats. Upon post-mortem examination, all 13 goats exhibited unilateral pulmonary consolidation. Seven goats had a unilateral hypoechoic pleural effusion. At necropsy, the related lung was consolidated and the pleural fluid appeared turbid and greenish. Pleural abscessiation detected in five goats was confirmed post-mortem. Twenty-eight goats had a bright, fibrinous matrix extending over the chest wall containing numerous anechoic fluid pockets with medial displacement and compression of lung tissue. Echogenic tags imaged floating in the fluid were found upon post-mortem examination to be fibrin. In two goats, a consolidated right parenchyma was imaged together with hypoechoic pericardial effusions with echogenic tags covering the epicardium. At necropsy, the right lung was consolidated in three goats and fibrin threads were found covering the epicardium and pericardium. In goats with CCPP, the extension and the severity of the pulmonary changes could not be verified with clinical certainty in most cases, whereas this was possible most of the time with sonography, thus making the prognosis easier. Ultrasonographic examination of the pleurae and the lungs helped in the detection of various lesions.

    Objective: To evaluate the mammographic and ultrasonographic findings of sclerosing adenosis, a relatively uncommon entity which may sometimes mimic carcinoma. Materials and methods: A retrospective review of the records of 33700 women, who have undergone mammographic examination at our institution between January 1985 and July 2001 revealed 43 histopathologically proven sclerosing adenosis. The history, physical examination, mammographic and ultrasonographic findings were analyzed in all patients. In 30 patients, the nonpalpable lesions were preoperatively localized by the needle-hookwire system under the guidance of mammography (n=22) or ultrasonography (US) (n=8). Radiological features were correlated with histopathological findings. Results: The age of the patients varied between 32 and 55 years (mean, 43.7 years). Only two patients had a family history of breast cancer. In six patients, the presenting complaint was mastalgia. A palpable mass was present in 13 cases. The mammographic findings were; microcalcifications in 24 (55.8%) (clustered in 22, diffuse in two), mass in five (11.6%), asymmetric focal density in three (6.9%), and focal architectural distortion in three (6.9%) patients. Four of the masses were irregularly contoured, while one was well-circumscribed. On US, focal acoustic shadowing without a mass configuration was noted in the three patients who showed asymmetrical focal density on mammography. In eight patients, who showed normal mammograms, a solid mass was detected on US. Two masses had discrete well-circumscribed oval or lobulated contours, while six showed microlobulation and irregularity. In one case, the irregularly contoured mass had marked posterior acoustic shadowing. Two of the three patients, who had focal architectural distortion on mammograms, had an irregularly contoured solid mass, while the third presented as focal acoustic shadowing without a mass configuration. Conclusion: Sclerosing adenosis mostly presents as a nonpalpable

    To evaluate ultrasonographic (US) findings of right-side colonic diverticulitis and to correlate them with pathologic findings. Twenty nine patients with surgically (n=7) and radiographically (n=8) proven diverticulitis in the cecum and ascending colon for the past five years were included in this study, and they all underwent US due to right lower quadrant abdominal pain. US findings were analyzed by two radiologists with a special emphasis on: (1) the presence, size, and internal echo of hypoechoic lesion bulging out from the colonic wall (thickened diverticulum), (2) changes in the adjacent cecum and ascending colon, (3) changes in the adjacent mesentery, (4) accompanying fluid collection, and (5) the presence of lymphadenopathy. US finding of 18 surgically proven patients were correlated with pathologic findings. On US, 25 of 29 patients (86.2%0 were found to have thicken diverticulum with the greater dimension of 8-20 mm (mean,, 12 mm). Wall thickening of the adjacent cecum and ascending colon was seen in 28 patients (96.5%), and 22 (75.9%) of them had eccentrically thickened wall. Comparing US findings with pathologic findings in 18 surgically proven patients, all revealed to have inflamed diverticulum on surgery, but only 15 showed thickened diverticulum on US. In 12 patients, fecalith, purulent exudates, and hemorrhage were found within diverticulum on surgery. In case of diverticulitis containing fecalith, all of their echogenecities were increased. All patients showed wall thickening of the adjacent colon and increased echogenecity of the adjacent mesentery on US. Pathologic findings of these thickened walls contained nonspecific inflammatory change and hemorrhage while the mesentery with an increased echogenecity contained purulent or hemorrhagic exudates. Ultrasonography can diagnose the right-side colonic diverticulitis when there is the presence of thickened diverticulum in the area with the thickened right side colonic wall in patients with right

    The radiographic and ultrasonographic findings in 26 cows with traumatic reticuloperitonitis were compared. The cows were divided into three groups based on the radiographic findings; the first group consisted of 12 cows in which the principal radiographic finding was a foreign body penetrating the reticulum; the second group contained four cows in which the principal radiographic finding was gas shadows or a gas-fluid interface, the third group consisted of 10 cows that had no reliable radiographic evidence of traumatic reticuloperitonitis, such as an abnormal contour, position or shape of the reticulum. In no case could the foreign bodies be visualised by ultrasonography. In all the cows except one with radiographic evidence of abnormal gas inclusions and gas-fluid interfaces, ultrasonography revealed echogenic, partitioned and capsulated structures with central hypoechogenic cavities. In addition, in some of the cows with no radiographic evidence of the condition, severe changes indicative of inflammatory processes were visible by ultrasonography

    To evaluate the distribution of color flow signals on color Doppler ultrasonography of vascular leiomyomas and to correlate them with pathologic findings. We retrospectively analyzed color Doppler ultrasonographic images and pathologic slides of six vascular leiomyomas. We classified the patterns of distribution of color flow signals into localized compact cluster types and non-cluster types, and the pathologic findings into three subtypes: solid, venous and cavernous. All cases showed well-defined homogenous hypoechoic subcutaneous masses on gray-scale ultrasonography. Three cases showed localized compact cluster types on color Doppler ultrasonography, one in each subtype (solid, venous and cavernous). For the three non-cluster types, again there was on in each subtype. In addition, on pathologic analysis the zone of the localized compact cluster of color flow signals coincided with a cluster of larger, vascular caliber masses. Localized compact clusters of color flow signals on color Doppler ultrasonography were seen in 50% of our cases and correlated with a cluster of larger vascular caliber in the mass. But the pattern of distribution of color flows didn't show a correlation with pathologic type

    To describe mammographic and ultrasonographic findings of previous chemoport insertion sites. We included patients who had abnormal findings at chemoport insertion sites on mammography and ultrasonography from 224 patients who underwent chemoport insertion and breast imaging at our institution between January, 2005, and December, 2007. Abnormal findings were identified in 16 mammographies and 14 ultrasonographies in 10 patients. The mean age was 50.9 years and the age range was from 44 to 67 years. Abnormal findings on mammography and ultrasonography were retrospectively analyzed according to ACR/BI-RADS. All cases were followed up with imaging studies for 2 years to confirm changes after chemoport insertion. Of the abnormal findings identified on mammography, focal asymmetry (7/16) was the most common. Other abnormal findings included mass (6/16), skin retraction (2/16), residual chemoport tip (1/16), and trabecular thickening (1/16). Of the abnormal findings seen on ultrasonography, skin thickening (12/14) was the most common. Other abnormal findings included mass (5/14), diffuse increased echogenicity of subcutaneous tissue (1/14), and a localized skin nodule (1/14). Abnormal findings on mammography and ultrasonography were located in the upper outer quadrant in 5 patients, upper inner quadrant in 3 patients, and mid upper portion in 1 patient. In 1 patient, the abnormal finding was only identified in the mediolateral oblique view of her mammography. Radiologists should be aware of potential abnormal findings on mammography and ultrasonography following chemoport insertion. In particular, ultrasonography is a very useful modality for detecting skin complications after chemoport insertion

    Full Text Available The implantation of the fertilized egg outside the uterine cavity leads to the development of ectopic pregnancy. The incidence of ectopic pregnancy is 1/100 births. The most common place of ectopic implantation of the fertilized ovum is the oviduct (98% with predilection for the ampullar part of the Fallopian tube. The aim of this study was to determine the predictive importance of beta-hCG and progesterone concentration compared to ultrasonographic finding in the ectopic pregnancy diagnosis.We examined 24 patients with ectopic pregnancies which we divided according to the days of amenorrhea into two groups: the first group with the total of 28 patients from 16–42 days and another group of 8 patients with amenorrhea longer than 42 days. The control group was comprised of 20 patients with vital intrauterine pregnancy, gestational age of 42-52 days. Blood samples for quantitative determination of hormones were collected on three occasions after 48 hours in the forenoon time in the examined and control group of pregnant women. Ultrasonographic examinations of all pregnant women were carried out immediately after blood sampling, with the trans-vaginal approach using "make loop" option, and measurements with an accuracy of 0.1 mm.Mean values for beta-hCG range from 698-1774 mlU/ml in the first group of pregnant women, and in the second group of 1896 mlU/ml to 4410 mlU/ml with a statistically significant difference compared to the values in the control group (p <0.001. The concentration of progesterone in the first group of women ranging from 41-70 nmol/l, and in the second group of 76-94 nmol/l which is also the statistically significant difference compared to the control group (p<0.002. We have shown that ultrasonographic finding with its parameters reliably predicts the values of biochemical parameters both in normal intrauterine pregnancy and in the case of ectopic pregnancy.Embryo viability and implantation place condition the values of

    The purpose of this study was to analyze the ultrasonographic (USG) findings of Kikuchi cervical lymphadenopathy in pediatric patients. Between April 2007 and September 2016, 84 children (42 male and 42 female; mean±standard deviation age, 12.9±3.2 years; range, 5 to 18 years) confirmed with Kikuchi disease were enrolled. Clinical findings and USG findings of Kikuchi cervical lymphadenopathy were retrospectively reviewed. Localized symptoms, systemic symptoms, and laboratory findings including the white blood cell count, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) were analyzed. An analysis of the USG findings included evaluation of the location, size, and presence of intranodal abscess; intranodal calcification; perinodal fat swelling; localized fluid collection; and loss of nodal echogenic hilum. Among the patients, 49 (58%) showed localized tenderness at the cervical lymphadenopathy. Fever was present in 55 (66%), while 27 (32%) had prolonged fever. Of 74 with lab results, 54 (73%) had leukopenia but none had leukocytosis. Among the same 74, there was a high ESR (>50 mm/hr) in 10 (14%) and a high CRP level (>5 mg/dL) in seven (9%). The USG findings of most of the patients (n=72, 86%) showed unilateral neck involvement, especially in the left side neck (45 of 72, 63%). The most common site of Kikuchi lymphadenopathy involvement was the area at cervical lymph node level V, at the posterior triangle (n=77, 92%). Conglomerated nodal distribution (n=57, 68%), preserved central nodal echogenic hilum (n=84, 98%), and perinodal fat swelling (n=55, 65%) were common USG findings in the children with Kikuchi. In addition, multiple cervical lymph nodes showed a relatively even size distribution (n=73, 87%). The common USG findings of Kikuchi disease in the pediatric population of our study were multiple conglomerated unilateral cervical lymphadenopathy showing perinodal fat swelling and even size distribution.

    To demonstrate the ultrasonographic findings in the diagnosis of intraductal papilloma by comparing it with mammography and ductography. The findings of mammography (n = 22), ultrasonography (n= 15), and ductography (n = 5) were analyzed in 25 women with intraductal papilloma. The mammographic findings were asymmetric focal increase in density (n = 4 : 18%), mass without calcification (n = 6 : 27%), mass with calcification (n = 2 : 9%), and calcification only (n = 1 : 5%). Nine studies (41%) showed no abnormal findings. The ultrasonographic findings were ductal dilatation with a mass (n = 7 : 47%), mass only (n = 5 : 33%),and intra cystic mass (n = 3 : 20%). There is no case of normal findings on ultrasonography. Three ductograms (60%)showed a filling defect within duct : the other two studies were normal. Ultrasonography offers very useful findings in early detecting the intraductal papilloma in conjunction with mammography and ductography

    We wanted to evaluate the ultrasonographic findings of bifid median nerve and its clinical significance. We retrospectively reviewed five cases (three men and two women, mean age: 54 years) of incidentally found bifid median nerve from 264 cases of clinically suspected carpal-tunnel syndrome that were seen at our hospital during last 6 years. Doppler sonography was performed in all five cases and MR angiography was done in one case for detecting a persistent median artery. The difference (ΔCSA) between the sum of the cross-sectional areas of the bifid median nerve at the pisiform level (CSA2) and the cross-sectional area proximal to the bifurcation(CSA1) was calculated. The incidence of a bifid median nerve was 1.9%. All the patients presented with a tingling sensation on a hand and two patients had nocturnal pain. All the cases showed bifurcation of the nerve bundle proximal to the carpal tunnel. The margins appeared relatively smooth and each bundle showed a characteristic fascicular pattern. A persistent median artery was noted between the bundles in four cases. ΔCSA was more than 2 mm 2 in four cases. Bifid median nerve with a persistent median artery is a relatively rare normal variance and these are very important findings before performing surgical intervention to avoid potential nerve injury and massive bleeding. We highly suggest that radiologists should understand the anatomical characteristics of this anomaly and make efforts to detect it

    We evaluated ultrasonographic findings and the corresponding histopathological characteristics of breast cancer patients with Breast Imaging Reporting and Data System (BI-RADS) category 1 mammogram. We retrospectively reviewed the ultrasonographic findings and the corresponding histopathological features of 45 breast cancer patients with BI-RADS category 1 mammogram and 537 controls with mammographic abnormalities. We evaluated the ultrasonographic findings including mass shape, periphery, internal and posterior echo pattern, interruption of mammary borders and the distribution of low-echoic lesions, and the corresponding histopathological characteristics including histological classification, hormone receptor and human epidermal growth factor receptor 2 status of invasive ductal carcinoma and ductal carcinoma in situ, histological grade, mitotic counts and lymphovascular invasion in individual cases of BI-RADS category 1 mammograms and compared with those of the control group. The ultrasonographic characteristics of the BI-RADS category 1 group were characterized by a higher ratio of round shape (P<0.001), non-spiculated periphery (P=0.021), non-interruption of mammary borders (P<0.001) and non-attenuation (P=0.011) compared with the control group. A total of 52.6% of low-echoic lesions were associated with spotted distribution in the BI-RADS 1 group, whereas 25.8% of low-echoic lesions were associated with spotted distribution in the control group (P=0.012). As for histopathological characteristics, there was a statistically higher ratio of triple-negative subtype (P=0.021), and this particular tendency was detected in histological grade 3 in the BI-RADS category 1 group (P=0.094). We evaluated ultrasonographic findings and the corresponding histopathological characteristics for BI-RADS category 1 mammograms and noted significant differences among these findings in this study. Evaluation of these ultrasonographic and histopathological characteristics may provide

    To characterize the sonographic findings of torsed testicular appendages and to evaluate the sonographic findings in making erroneous diagnosis of epididymitis or torsion of testis in prepubertal children. From June 2010 to November 2012, we retrospectively analyzed the duplex sonography of fifteen children with torsion of testicular appendages. The presence or absence of the extratesticular nodule and secondary inflammatory changes were evaluated. Six patients had follow-up sonography and two patients underwent surgery. Sonography demonstrated the extratesticular nodule in 13 (87%) children. Four of these 13 children were misdiagnosed as epididymitis due to imperceptions of the nodule. Out of remaining two (13%) children without the nodule, one mimicked epididymitis and the other was misdiagnosed as torsion of testis. Secondary inflammatory changes included enlarged epididymis in 14 children (93%), scrotal wall edema in 11 (73%), hydrocele in 10 (67%), and enlarged testis in 3 (20%). Ultrasonographic findings of secondary inflammatory changes in the absence or imperception of the nodules for epididymo-testicular groove or epididymal head may suggest an erroneous diagnosis of epididymitis or torsion of testis in children with torsed testicular appendages. Meticulous evaluation for the nodule is important when differentiating the torsed testicular appendages from the two entities of prepubertal children.

    Acute appendicitis is the most common surgical disease of acute abdomen, But the diagnosis of acute appendicitis is often difficult, and not in frequently, operation for appendicitis is performed only to find a normal appendix. Various radiological examinations have been proposed to improve diagnostic accuracy of appendicitis. The purpose of this study was to improve the diagnostic accuracy of appendicitis, and to decline negative exploration. High resolution real time ultrasonographical examination using graded compression was performed in 57 consecutive patients who were clinically suspected of appendicitis. Autors analysed ultrasonographical, surgical, and clinical follow up findings. The results were are follows: 1. Ultrasonographical finding of acute appendicitis was visualization of appendix as a tubular structure with one bline end, or target phenomenon. 2. Hypoechoic area over the appendix was thought to be a sign of periappendiceal abscess. 3. The sensitivity of US diagnosis of acute appendicitis in this study was 92.8% with a specificity of 93.1%. The overall accuracy was 93.0%. 4. In control group of 50 individuals, the abnormal appendix was not visualized. 5. In cases of clinically suspected appendicitis, the US evaluation with graded compression technique is very accurate and effective examination.

    The ultrasonographic features of stomach cancer were studied in 43 patients who were diagnosed by double contrast UGI study and endoscopy. Ultrasonographic study was performed immediately after UGI study and the findings were correlated with USI study. The authors observed infiltrative lesions causing thickening of gastric wall, which can be localized (16 of 31) or diffuse(15 of 31). 9 cases were exogastric masses, sonographic findings were not found in the lesions occupying the cardia (3 of 5) Ultrasonography is useful in demonstrating the extent of the tumor and the presence of metastasis elsewhere in the abdomen, facilitating tumor staging and evaluation of the response to therapy

    To assess the ultrasonographic features of post-biopsy change 6 months after 11-gauge vacuum-assisted large-core breast biopsy of pathologically proven benign lesions. Using the literature as a reference, we hypothesized that large-core breast biopsy would result in tissue changes that may mimic malignancy and may be more apparent on ultrasonography than on mammography. Two radiologists whose subspecialty is breast imaging retrospectively reviewed the pre-biopsy and 6-month follow-up sonograms of 24 patients with pathologically proven benign lesions. The images were assessed for the number and type of ultrasonographic features. A Breast Imaging Reporting and Data System (BI-RADS) category was assigned to each lesion before biopsy and at 6-month follow-up. The composition of breast tissue surrounding the lesion was assessed as fatty, mixed fibroglandular or dense. The frequency of ultrasonographic changes at 6 months after 11-gauge vacuum-assisted large-core breast biopsy was more frequent than the rate of post-biopsy change previously reported to occur mammographically. The nature of these changes may mimic malignancy in some cases. The ultrasonographic appearance of the breast after large-core breast biopsy may mimic malignancy and is, therefore, a potential pitfall when interpreting a post-biopsy sonogram. (author)

    To describe the ultrasonographic (US) findings of type IIIa biliary atresia. We retrospectively reviewed a medical database of patients pathologically confirmed to have biliary atresia, Kasai type IIIa, between January 2002 and May 2013 (n=18). We evaluated US findings including the visible common bile duct (CBD), triangular cord thickness, gallbladder size and shape, and subcapsular flow on color Doppler US; laboratory data; and pathological hepatic fibrosis grades. We divided them into two groups-those with visible (group A) and invisible (group B) CBD on US-and compared all parameters between the two groups. CBD was visible on US in five cases (27.8%; group A) and invisible in 13 cases (72.2%; group B). US was performed at an earlier age in group A than in group B (median, 27 days vs. 60 days; P=0.027) with the maximal age of 51 days. A comparison of the US findings revealed that the triangular cord thickness was smaller (4.1 mm vs. 4.9 mm; P=0.004) and the gallbladder length was larger (20.0 mm vs. 11.7 mm; P=0.021) in group A. The gallbladder shape did not differ between the two groups, and the subcapsular flow was positive in all cases of both groups. There was no significant difference in the laboratory data between the two groups. Upon pathological analysis, group A showed low-grade and group B showed low- to high-grade hepatic fibrosis. When CBD is visible on US in patients diagnosed with type IIIa biliary atresia, other US features could have a false negative status. A subcapsular flow on the color Doppler US would be noted in the type IIIa biliary atresia patients.

    The aims of this study were to evaluate the sonographic findings of patients with hereditary neuropathy with liability to pressure palsies (HNPP) and to examine the correlation between sonographic and electrophysiological findings. Nine patients whose electrophysiological findings indicated HNPP and whose diagnosis was confirmed by genetic analysis were enrolled in the study. The median, ulnar, peroneal, and tibial nerves were evaluated by ultrasonography. We ultrasonographically evaluated 18 median, ulnar, peroneal, and tibial nerves. Nerve enlargement was identified in the median, ulnar, and peroneal nerves at the typical sites of compression. None of the patients had nerve enlargement at a site of noncompression. None of the tibial nerves had increased cross-sectional area (CSA) values. There were no significant differences in median, ulnar, and peroneal nerve distal motor latencies (DMLs) between the patients with an increased CSA and those with a normal CSA. In most cases, there was no correlation between electrophysiological abnormalities and clinical or sonographic findings. Although multiple nerve enlargements at typical entrapment sites on sonographic evaluation can suggest HNPP, ultrasonography cannot be used as a diagnostic tool for HNPP. Ultrasonography may contribute to the differential diagnosis of HNPP and other demyelinating polyneuropathies or compression neuropathies; however, further studies are required.

    In the 88 cases of biliary disease, which was proven in Seoul Red Cross Hospital from Jan, 1980 to Dec. 1981, comparative studies were made with oral and IV cholecystocholangiographic findings and ultrasonographic findings. The results were: 1. In the 18 cases of GB stones, there are 17 cases (94.4%) of positive findings in cholecysto-cholangiography with detection of stone in 7 cases (38.9%), while in sonographic study, 16 cases (88.9%) are shown positive findings with detection of stone in 11 cases (61.1%). 2. In the 17 cases of acalculous cholecystitis, the diagnostic accuracy is 88.2% in cholecystocholangiography and 64.7% in sonography. 3. In the 7 cases of CBD stones, all cases are shown positive findings in cholecystocholangiography with detection of stone in only one case (14.3%), while 6 cases (85.7%) of positive findings are shown in sonography with detection of stone in all cases. 4. I.V. cholangiography is more accurate diagnostic procedure rather than oral GB study in the cases of poor or non-functioning GB. 5. Sonography is the choice of procedure in the diagnosis of stones, while in the cases of cholecystitis, cholecystocholangiography is more useful diagnostic procedure

    This study was deigned to evaluate the ultrasonographic findings of subcutaneous and intramuscular sparganosis. Nine cases of histologically proven subcutaneous and intramuscular sparganosis lesions in seven patients (mean patient age, 59 years; M:F = 6:1) were reviewed retrospectively. Two patients had recurrent sparganosis. A color Doppler examination was performed in all cases. A prior history of ingestion of raw snake meat was noted for two patients. Patients presented with a palpable mass and induration (n = 7) and dull pain (n = 4). Lesion locations were in the thigh (n = 4), lower leg (n = 2), chest wall (n = 1), an inguinal location (n = 1) and the neck (n = 1). Five lesions were in the subcutaneous fat layer and four lesions had intramuscular locations. Calcification was noted in two cases. All cases showed heterogeneous hypoechoic serpiginous tubular-and-oval lesions. The lesions were conglomerated or discrete in appearance. All nine cases showed the presence of lesions with a multi-layered wall with variable intraluminal echogenicity, at least in one segment of the lesion. Increased vascularity was noted on color Doppler examinations in two patients with pain. Subcutaneous or intramuscular sparganosis should be included in the differential diagnosis when a serpiginous tubular-and-oval lesion is noted that is seen with a multi-layered wall with variable intraluminal echogenicity

    The purpose of the study was to explore the role of sonography for women with a suspected urethral diverticulum and to evaluate the transperineal ultrasonographic findings of female urethral diverticulum. Eight women (mean age, 44 years) who presented with urethral symptoms and clinically suspected urethral diverticula underwent transperineal ultrasonography; sagittal and coronal images were obtained. Sonography was done with either a 7-5 MHz curved array transducer or 10-5 MHz linear transducer, placed on the perineum at the level of the urethra. Ultrasonograms were assessed for the presence, size, location, shape, echogenicity, and septum. Five patients underwent voiding cystourethrography (VCUG). Results of the sonograms and VCUGs were compared with each other and with surgical findings. Longitudinally, all lesions were located in a middle third of the urethra. In axial plane, 4 diverticula wrapped around 50-100% of the urethra. 3 cases located posteriorly, and 1 case laterally. Seven diverticula contained echogenic debris. Three cases have septa in the diverticulum. The outer margin of the diverticula was smooth in 2 patients and was lobulated in 6 patients. In 3 of 5 cases who underwent VCUG, diverticula were filled with contrast, and appeared to be smaller than those of ultrasonography. In addition, all were single diverticulum in VCUG. Most urethral diverticulum were located in a middle third of the urethra, wrapped around the urethra or round posteriorly. Many cases appear unilocular or multilocular with echogenic debris. Transperineal ultrasonography is easy to operate and accurate for showing urethral diverticulum, and it may be useful for diagnosing this group of women with urethral symptoms and suspected urethral diverticulum. It provides information on the extent and location of the diverticulum, which are important in surgical excision.

    To clarify the characteristic sonographic features of benign soft tissue tumors and to evaluate the usefulness of sonographic imaging. We retrospectively reviewed ultrasonographic images of 70 cases in 68 patients with histologically proved benign soft tissue tumors. The tumors include 33 lipomas, 11 hemangiomas, 11 lymphangiomas, 7 neurilemmomas, 4 epidermoid cysts, 2 fibromas, 1 mesenchymoma, and 1 myxoma. The sonographic appearances of the lesions were mainly solid in 53 cases(33 lipomas, 8 hemangiomas, 2 lymphangiomas, 7 neurilemmomas, 2 fibromas and 1 mesenchymoma), mainly cystic in 14 cases(1 hemangioma, 8 lymphangiomas, 4 epidermoid cysts, and 1 myxomal), and mixed in 3 cases(2 hemangiomas and 1 lymphangioma). Although an accurate histologic prediction could not be made in most cases, certain patterns appeared to be characteristic of specific tumor types. 26 cases(78%) of lipoma were seen as lentiform, iso- or hyperechoic, solid mass. Hemangioma had variable appearance and characteristic calcifications were seen in 3 cases. Unicameral or multiseptated cystic mass with variable thickness of echogenic septa and solid portion was the characteristic finding of lymhangioma. Neurilemmoma showed lobulated, oval to round , relatively hypoechoic mass or with without internal cystic portion. Sonographic evaluation of benign soft tissue tumors is useful in demonstrating the location, size, extent, and internal characteristic of the mass. A relatively confident diagnosis can made when the characteristic features of the benign soft tissue tumor are present on sonographic imaging

    To evaluate the ultrasonographic findings of testicular teratoma arising in pre-pubertal children. We studied 6 cases in 5 patients with pathologically proven testicular teratoma. Ultrasonography was performed in all cases and MRI in 5 cases. The location, size, shape, margin and internal echo pattern of the lesion were evaluated on ultrasonography and the shape, signal intensity and presence or absence of contrast enhancement were evaluated on MRI. The shape of all cases was round or oval and the lesion size ranged from 0.5 to 3.5 cm (average, 1.7 cm). Four of 6 cases were seen as cystic lesions, Three of which were multilocular and one was unilocular. The cystic lesions were filled with echo-free fluid without any solid component. The inner wall and septa were minutely granulated. One of 6 cases was seen as a predominantly cystic lesion containing heterogeneous, high echoic portions. One case was seen as a heterogeneous mixed echoic lesion with dirty posterior sonic shadowing. Three of the 4 cases seen as a cyst on ultrasonography were also seen as a cyst on MRI. In one case seen as a predominantly cystic lesion on ultrasonography, the periphery of the lesion was hypointense and the center was hyperintense on T2-weighted image. The remaining case seen as a heterogeneous mixed echoic mass was markedly heterogeneous in signal intensity both on T2- and T1-weighted images and hyperintense fat components were noted. Contrast enhancement was not seen in any of the 4 cases. On ultrasonography, pre-pubertal testicular teratoma is commonly seen as a multilocular or unilocular cyst and a minutely granulated appearance is noted in the inner wall or septa of the cystic lesion

    The spleen is the most frequently injured organ in adults who sustain blunt abdominal trauma. Splenic trauma accounts for approximately 25% to 30% of all intra-abdominal injuries. The management of splenic injury has undergone rapid change over the last decade, with increasing emphasis on splenic salvage and non-operative management. Identifying the presence and degree of splenic injury is critical in triaging the management of patients. Imaging is integral in the identification of splenic injuries, both at the time of injury and during follow-up. Although CT remains the gold standard in blunt abdominal trauma, US continues to play an important role in assessing the traumatized spleen. This pictorial review illustrates the various ultrasonographic appearances of the traumatized spleen. Correlation with other imaging is presented and complications that occur during follow-up are described.

    Today, ultrasound imaging is being widely used to assess soft tissue lesions in the maxillofacial region. However, ultrasound investigations of intra-osseous lesions are rare, especially for tumors of the jaws. This report emphasized the capability of this useful imaging modality in identification of the characteristics of malignant conditions involving the bone. Mesenchymal chondrosarcoama, one of the unusual malignant conditions of the jaw, was presented in a young male with significant facial swelling. Different imaging modalities parallel with the histopathologic investigation confirmed the diagnosis. Interestingly, destruction of the bony cortex and new bone formation with a characteristic 'sun ray appearance', highly suggestive of sarcomas, was manifested on the ultrasonograph. Thus, this report presented the ultrasonographic features of chondrosarcoma of mandible and considered the ultrasonography to be a useful imaging modality to evaluate intra-osseous jaw lesions.

    We performed a retrospective analysis of ultrasonographic features of hepatic hemangiomas according to tumor size. After an initial ultrasonographic examination, 5l hepatic hemangiomas in 4l patients were confirmed by one or combined examinations of 99mTc RBC SPECT, computed tomography, magnetic resonance imaging. angiography or ultrasonographic follow up. Definition of margin, internal echogenicity,peripheral rim and posterior enhancement were evaluated by two radiologists. Forty seven cases(92%) of 51 hemangiomas appeared to be well defined. Of 29 hemangiomas with less than 3cm in diameter. 25 cases (86%)showed homogeneous internal echogenicity. Of 22 hemangiomas with above 3 cm in diameter, 16 cases (73%) showed inhomogeneous echogenicity. Of 12 hemangiomas (24%) with peripheral rim, nine cases revealed hyperechoic rim and two hypoechoic rim. The remaining one case showed hyperechoic rim and hypoechoic rim alternately. Hemangiomas with greater than 3cm in diameter had higher incidence of inhomogeneous echogenicity, peripheral rim and posterior enhancement than those less than 3 cm(P<0.05). The majority of small hepatic hemangiomas are well defined homogeneous hyperechoic masses. On the other hand, large hemangiomas tended to have higher incidence of inhomogeneous internal echogenicity, posterior enhancement and a peripheral hyperechoic rim. A hyperechoic mass with a hypoechoic rim should also be considered as a candidate for hepatic hemangioma

    This study evaluated the structural changes in the reproductive tract of Asiatic black bears using serial transrectal ultrasonography. In addition, the ultrasonographic observations were compared with the results of vaginal cytology and hormonal analyses. The collection of blood for hormonal analysis, vaginal cytology and transrectal ultrasonography was performed in two bears (Bears 1 and 2) from June 2011 to August 2013 without mating and in a third bear (Bear 3) from April to December 2012, allowing natural mating. Serial ultrasonographic observations showed cyclic changes in ovarian structures (e.g. emergence of small follicles, growth and ovulation of dominant follicles and corpus luteum (CL) formation) during the reproductive cycles of the three bears. The diameter of the uterine horns remained similar throughout the reproductive cycle in Bears 1 and 2, and it remained similar from April until October, but an enlargement containing foetuses was observed in Bear 3 in December. The ultrasonographic observations were consistent with the data obtained through vaginal cytology and progesterone analysis during the reproductive cycle. An average of 4.0 (±0.4) dominant follicles was observed during the oestrous stage (May-August), during which the superficial cells accounted for >90% of the total vaginal cells. In addition, the detection of an average of 2.6 (±0.2) CL was associated with increased plasma progesterone concentrations (3.0 ± 0.4 ng/ml) between June and December (near hibernation). In conclusion, serial transrectal ultrasonography demonstrated yearly oestrous (ovulation) cycles via follicular dynamics and CL formation on ovaries, accordingly with vaginal cytology and hormonal level in the Asiatic black bear. © 2014 Blackwell Verlag GmbH.

    Diagnostic ability of duplex Doppler ultrasonography relying on resistive index is limited when clinical symptoms and signs of rejection are subtle or renal dysfunction is caused by other conditions such as urinary tract infection. To investigate the significance in the changes of renal pelvis, a combined analysis of resistive index and ultrasonographic findings in cases of renal pelvis dilatation and mucosal thickening was undertaken. A mean resistive index was calculated from Doppler measurements of the main, segmental and interlobar arteries. The cause of mucosal thickening was retrospectively analysed using the clinical and laboratory findings. Twenty three cases of renal pelvis dilatation and 17 cases of mucosal thickening were found in a total of 159 renal transplantation cases. In 14 of the 23 cases with renal pelvis dilatation, renal function was normal and their mean resistive index was 0.64 ± 0.04. Pelvis and ureter dilatation caused by ureteral stenosis or compression was demonstrated in 6 cases and their mean resistive index (0.72 ± 0.05) was increased. Mucosal thickening of renal pelvis was found in 7 of 32 cases with acute injection and in 2 of 13 cases with chronic rejection, but their mean resistive index was not different from that of the cases without pelvic mucosal changes. Three cases of acute rejection associated with urinary tract infection and 2 cases of chronic rejection in whom resistive indices were indeterminate, but mucosal thickening of the renal pelvis was prominent at ultrasonography. In renal transplant patients having indeterminate resistive index and mucosal thickening of the renal pelvis, ultrasonographic features must be correlated with the clinical and laboratory findings for an accurate diagnosis and treatment of renal dysfunction

    We investigated the ultrasonographic (US) appearance of metapIastic squamous breast carcinoma with the pathologic correlation. During an 8-year period, the US appearances of 10 patients with metaplastic squamous breast carcinoma were retrospectively analyzed on the basis of the Breast Imaging and Reporting Data System (BI-RADS) - US lexicon. These 10 patients included 9 patients having invasive adenocarcinomas of the breast with more than 30% squamous metaplasia, and one patient had pure primary squamous cell carcinoma. We correlated the US findings with the pathologic findings. On US, the majority of the tumors showed ovaI shapes (70%), indistinct margins (50%), parallel orientation (80%), echogenic halos (60%), complex echogenicity with solid and cystic components (60%), and posterior enhancement (70%). The findings of calcifications (20%) and metastatic axillary lymph nodes (10%) were rare. On pathologic examination, half of the tumors showed infiltrative microscopic margins. All six cases showing complex echogenicity with solid and cystic components on US were pathologically related to the cystic or necrotic portion, and three of these cases had hemorrhage. On US, metapIastic squamous breast carcinoma mainly manifested as oval, complex, echoic masses with indistinct margins and posterior enhancement that was pathologically related to the cystic or necrotic portions

    Serial CT investigations of 3 patients with histologically confirmed Creutzfeldt-Jakob disease revealed persisting slight brain atrophy to progressive extreme atrophy corresponding to the absolute, not the individual duration of illness. No correlation was observed between CT findings and the patients condition or electroencephalographic results. In one case with a duration of about 16 months and a terminal brain weight of 750 g a massive bilateral, later unilateral subdural hygroma appeared which probably was caused by retraction of the brain showing an enormous atrophy.

    The goal of this study was to perform a retrospective analysis of the ultrasonographic findings associated with low-grade endometrial stromal sarcoma. Ten pathologically confirmed cases of low-grade endometrial stromal sarcoma at our institution from January 2007 to April 2014 were retrospectively reviewed. All patients underwent a preoperative transvaginal ultrasound. Two radiologists came to a consensus regarding the location, size, margin, and echogenicity of the tumor, as well as the presence of intratumoral cystic degeneration and its extent and configuration. Low-grade endometrial stromal sarcoma manifested as an intramural mass protruding into the endometrial cavity (n=6) or as a purely intramural mass (n=4). The maximal diameter of the lesion ranged from 4 to 9.1 cm (mean, 6.2 cm). The imaging features of low-grade endometrial stromal sarcoma were variable: six cases involved predominantly solid masses containing cystic degeneration, one was a predominantly unilocular cystic mass, two were ill-defined infiltrative solid masses, and one was a well-defined solid mass. Among the seven cases with internal cystic degeneration, five patients showed a multiseptated cystic area or a cystic area with multiple small clusters, while a unilocular cystic area within the tumor was found in two patients. Low-grade endometrial stromal sarcoma is associated with variable ultrasonographic findings with regard to the location, margin, and configuration of the lesion. Multiseptated cystic areas and multiple small areas of cystic degeneration are common.

    Hemodialysis via the internal jugular vein (IJV) has been widely used for patients with end stage renal disease (ESRD) patients, as they have a higher risk of arterial diseases. We investigated the ultrasonographic findings of the IJV and carotid artery (CA) in recipients of kidney transplantation (KT) and identified factors influencing IJV/CA abnormalities. We enrolled 120 adult KT recipients. Patients in group A (n = 57) had a history of IJV hemodialysis, while those in group B (n = 63) were not yet on dialysis or undergoing dialysis methods not involving the IJV. The day before surgery, we evaluated the state of the IJV and CA using ultrasonography. We followed patients with IJV stenosis for six months after KT. Ultrasonography revealed that four patients (7%) in group A had IJV abnormalities, while no patients in group B had abnormalities (P = 0.118). Of the four patients with abnormalities, one with 57.4% stenosis normalized during follow- up. However, another patient with 90.1% stenosis progressed to occlusion, while the two patients with total occlusion remained the same. Twenty patients in group A (n = 11) and B (n = 9) had several CA abnormalities (P = 0.462). Upon multivariate analysis with stepwise selection, height and age were significantly correlated with IJV stenosis (P = 0.043, odds ratio = 0.9) and CA abnormality (P = 0.012, odds ratio = 1.1), respectively. IJV abnormalities (especially with a history of IJV hemodialysis) and CA abnormalities may be present in ESRD patients. Therefore, we recommend ultrasonographic evaluation before catheterization.

    Beach volleyball is an overhead sport that subjects the hitting shoulder to intense functional loads. The purpose of this study is to identify ultrasonographically the prevalence of myotendinous alterations in professional Italian beach volleyball players at the Italian championship and to look for associations between ultrasound findings and the other data collected. Fifty-three beach volleyball players (31 women, 22 men) were recruited during the second stage of the Italian championship held in July 2012 in Rome, Italy. Clinical history was obtained from all subjects, followed by physical exam. Each athlete completed a questionnaire regarding sports activities. Bilateral ultrasonographic evaluation of the shoulders was then performed. Calcific tendinopathy of the rotator cuff of the hitting shoulder was identified ultrasonographically in 30% of the athletes. The mean age of the athletes with calcific tendinopathy was older than subjects with other abnormalities on ultrasonographic examination (33.1 years vs. 25.8 years, t-test; Pvolleyball players has a prevalence of 30% ultrasonographically, greater than that reported in the general population. In these athletes, the presence of calcific tendinopathy correlates positively with age.

    To investigate the serial CT findings of Paragonimus westermani infected dogs and the microscopic structures of the worm cysts using Micro-CT. This study was approved by the committee on animal research at our institution. Fifteen dogs infected with P. westermani underwent serial contrast-enhanced CT scans at pre-infection, after 10 days of infection, and monthly thereafter until six months for determining the radiologic-pathologic correlation. Three dogs (one dog each time) were sacrificed at 1, 3 and 6 months, respectively. After fixation of the lungs, both multi-detector CT and Micro-CT were performed for examining the worm cysts. The initial findings were pleural effusion and/or subpleural groundglass opacities or linear opacities at day 10. At day 30, subpleural and peribronchial nodules appeared with hydropneumothorax and abdominal or chest wall air bubbles. Cavitary change and bronchial dilatation began to be seen on CT scan at day 30 and this was mostly seen together with mediastinal lymphadenopathy at day 60. Thereafter, subpleural ground-glass opacities and nodules with or without cavitary changes were persistently observed until day 180. After cavitary change of the nodules, the migratory features of the subpleural or peribronchial nodules were seen on all the serial CT scans. Micro-CT showed that the cyst wall contained dilated interconnected tubular structures, which had communications with the cavity and the adjacent distal bronchus. The CT findings of paragonimiasis depend on the migratory stage of the worms. The worm cyst can have numerous interconnected tubular channels within its own wall and these channels have connections with the cavity and the adjacent distal bronchus

    Myofascial pain syndrome (MPS) is a common cause of musculoskeletal pain. Myofascial trigger points (MTrPs) have been repeatedly described by numerous authors. However, there have been few studies in which their existence and behavior was supported and their location confirmed. The purpose of this study was to determine whether diagnostic ultrasonography is an objective diagnostic tool which is able to significantly identify or detect the soft tissue changes in the region of clinically identified active MTrPs by using a rabbit experimental model. Ten MPS model rabbits were used in this study. We made an MPS animal model by causing the rabbits to overuse one leg for 3 weeks by cutting the contralateral L4 spinal nerve root. We compared the ultrasonographic findings of the taut band at pre-OP with those at post-OP during the consecutive three week period. To find the taut bands of the muscle, after skin exposure, the muscles were gently rubbed or pinched with the thumb and index finger on the two opposing surfaces of the muscle across the direction of the fibers. Then, the muscle was held in the same way, but with a 5-8 MHz stick probe being used in place of the thumb. After the palpation of various muscles, we selected the hardest and largest myofascial trigger nodule, in order to observe the ultrasonographic and power Doppler findings of the MPS. The size, shape, echogenecity and vascularity of the MTrPs were observed. The analysis of the results of the ultrasonography revealed that all MTrPs have a hyperechoic area. The mean thickness of the hyperechoic lesion in the biceps was 0.96±0.14 cm in the MPS site (at pre-OP?), and 0.49±0.12 cm at post-OP 3weeks (p < 0.01). The hyperechoic lesions in all of the studied biceps femoris of the rabbits were observed by high resolution ultrasonography. No definitively decreased vascularity was observed within the hyperechoic area by power Doppler imaging. Until now, there has been no objective method for the diagnosis of MPS

    The spontaneous infarction of benign breast lesions is a rare entity and hence is not usually considered in the differential diagnosis during radiologic or clinical examination. There have been a few published cases of infarction during pregnancy and lactation. In this study we report the ultrasonographic and pathologic features of a spontaneous infarction of a lactating adenoma with acute mastitis and abscess and a spontaneously infarcted fibroadenoma.

    To evaluate the ultrasonomammographic findings of breast fibroadenoma. We evaluated the ultrasonographic findings of histopathologically proved 135 fibroadenomas in 103 patients from January 1986 to September 1990, retrospectively. The ultrasonographic examinations were performed with a hand held linear array 5MHz transducer (Acuson 128(USA). Aloka 650, 280(Japan)). Asonopad was also used during the examinations. The common ultrasonographic findings of fibroadenomas usually showed smooth contour in 120 lesions(88.9%), oval or round shape in 114 lesions(84.4%), uniform homogeneous echogenecity in 106 lesions(78.5%), intermediate hypoechoic internal echo pattern in 105 lesions(77.8%), thin boundary echo in 117 lesions(86.7%), lateral shadowings in 97 lesions(72%), and posterior acoustic enhancement in 56 lesions(41%). The longitudinal/transverse ratio of fibroadenoma was revealed between 0.2 and 1.14 (mean 0.58) and usually under 1.0 (68.9%). Finally, most of fibroadenomas are easily diagnosed by ultrasonography but if differential diagnosis from malignant breast mass is difficult due to atypical appearance, other combined modalities such as filmmammography, fine needle aspiration biopsy and MRI are necessary

    Objectives The aim of the study was to describe the ultrasonographic and endoscopic appearance and characteristics of the caecum in asymptomatic cats, and to correlate these findings with histology. Methods Ex vivo ultrasonographic and histologic evaluations of a fresh caecum were initially performed. Then, 20 asymptomatic cats, privately owned or originating from a reproductive colony, were recruited. All cats had an ultrasonographic examination of the ileocaecocolic junction, where the thickness of the caecal wall, ileocolic lymph nodes and the echogenicity of the local fat were assessed. They all underwent a colonoscopy with a macroscopic assessment of the mucosa and biopsies for histology. Results An ultrasonographic hypoechoic nodular inner layer, which corresponded to the coalescence of multiple lymphoid follicles originating from the submucosa and protruding in the mucosa on histology, was visible in all parts of the caecum. The combined mucosa and submucosa was measured ultrasonographically and defined as the follicular layer. Although all cats were asymptomatic, 3/19 cats showed mild caecal inflammation on histology. The most discriminatory ultrasonographic parameter in assessing this subclinical inflammation was the thickness of the follicular layer at the entrance of the caecum, with a cut-off value of 2.0 mm. All cats (20/20) showed some degree of macroscopic 'dimpling' of the caecal mucosa on endoscopy. Conclusions and relevance Lymphoid follicles in the caecal mucosa and submucosa constitute a unique follicular layer on ultrasound. In asymptomatic cats, a subtle, non-clinically relevant inflammation may exist and this is correlated with an increased thickness of the follicular layer on ultrasound. On endoscopy, a 'dimpled aspect' to the caecal mucosa is a normal finding in the asymptomatic cat.

    Clinical signs, duration of illness, clinicopathologic findings, and ultrasonographic findings were evaluated in 12 llamas and 12 alpacas with malignant round cell tumors (MRCT). All but 1 animal died or was euthanized. Common clinical findings were anorexia, recumbency or weakness, and weight loss or poor growth. Peripheral lymphadenomegaly occurred in only 7 animals and was detected more often at necropsy than during physical examination. Common clinicopathologic abnormalities were hypoalbuminemia, acidosis, azotemia, anemia, hyperglycemia, and neutrophilia. Ultrasonography detected tumors in 4/6 animals. Cytologic evaluation of fluid or tissue aspirates or histopathology of biopsy tissue was diagnostic in 5/6 cases. A clinical course of 2 wk or less prior to death or euthanasia was more common in animals ≤ 2 y of age (9/11) than in older animals (6/13). Regular examination of camelids to include clinical pathology and evaluation of peripheral lymph nodes may result in early detection of MCRT. PMID:21358931

    Full Text Available Ultrasonographic diagnostics is a sovereign diagnostic method of discovering disorders in growth and development of embryo. The main aim of this research is The Comparison of Ultrasonographic Placenta Examination with Pathohistologic Treatment of Placenta considering those pregnancies previously verified to have embryo anomalies and which were ended by the procedure of feticide. During the period of 2001 – 2004, 15 pregnant women, with gestation between the 24th and 28th week, were hospitalized in our clinic. Ultrasonographic placenta examination was carried out during the expertise sonography immediately before deciding to commit feticide. The descriptive medical findings were divided into the clinical entities estimating the continuity of basal body, insertion, volume, and echo-structure of placenta substance. The procedure of feticide was carried out in regular treatments using intracardial application of 7,4 % KCl or transabdominal, intra-amnial instillation of 20 % NaCl under the control of ultrasound.The patients with the embryo anomalies were divided into three groups:I – the group with the diagnosis of embryo hydrocephalusII – the group with the diagnosis of other anomalies of growth of embryo's CNSIII – the group of patients with other embryo anomaliesPathohistologic placenta examinations were carried out in the Department of Pathology and Forensic Medicine in CC Kragujevac.The ultrasonographic placenta finding of the patients with the different embryo anomalies was not statistically very different (x2 – test; p=0,073. However, besides the lack of significant difference, what is reasonable considering the size of the sample, we notice quite different ultrasonographic findings of the placenta examination of the patients having the embryo with hydrocephalus in comparison to those patients having the other embryo anomalies of CNS. The ultrasonographic placenta examination of the patients having the other embryo anomalies was

    Full Text Available BackgroundThe ultrasonographic characteristics and difference for various subtypes of papillary thyroid carcinoma (PTC are still unclear. The aim of this study was to compare the ultrasonographic features of PTC according to its subtype in patients undergoing thyroid surgery.MethodsIn total, 140 patients who underwent preoperative thyroid ultrasonography (US and thyroid surgery between January 2016 and December 2016 were included. The ultrasonographic features and the Korean Thyroid Imaging Reporting and Data System (K-TIRADS category of each thyroid nodule were retrospectively evaluated by a single radiologist, and differences in ultrasonographic features according to the PTC subtype were assessed.ResultsAccording to histopathological analyses, there were 97 classic PTCs (62.2%, 34 follicular variants (21.8%, 5 tall cell variants (3.2%, 2 oncocytic variants (1.3%, 1 Warthin-like variant (0.6%, and 1 diffuse sclerosing variant (0.6%. Most PTCs were classified under K-TIRADS category 5. Among the ultrasonographic features, the nodule margin and the presence of calcification were significantly different among the PTC subtypes. A spiculated/microlobulated margin was the most common type of margin, regardless of the PTC subtype. In particular, all tall cell variants exhibited a spiculated/microlobulated margin. The classic PTC group exhibited the highest prevalence of intranodular calcification, with microcalcification being the most common. The prevalence of multiplicity and nodal metastasis was high in the tall cell variant group.ConclusionThe majority of PTCs in the present study belonged to K-TIRADS category 5, regardless of the subtype. Our findings suggest that ultrasonographic features are not useful for distinguishing PTC subtypes.

    Objectives Hypertension is a common cause of proteinuria in HIV-infected people. In cats, feline immunodeficiency virus (FIV) infection appears to be associated with proteinuria. Therefore, the results from systolic blood pressure (SBP) measurements in naturally infected FIV-positive cats were reviewed to assess whether hypertension contributes to the observed proteinuria in these cats. Ultrasonographic findings in FIV-positive cats were reviewed to complete renal assessment and to extend the scant knowledge on renal ultrasonography in cats. Methods Data from client-owned, naturally infected FIV-positive cats were retrospectively reviewed. To obtain a control group, records were reviewed from age-matched, privately owned, FIV-negative cats. Results Data from 91 FIV-infected and 113 control cats were compared. FIV-infected cats showed a significantly lower SBP ( P 0.4) occurred more frequently in FIV-infected cats ( P <0.001). Renal ultrasonography showed abnormalities in 60/91 FIV-infected cats, with hyperechogenic cortices in 39/91 and enlarged kidneys in 31/91. Conclusions and relevance Hypertension can be excluded as a common cause of renal damage leading to proteinuria in FIV-infected cats. Proteinuria and poorly concentrated urine are common in naturally infected FIV-positive cats, in contrast to azotaemia. Clinicians should cautiously interpret ultrasonographic abnormalities as these occur in over half of FIV-infected cats.

    Sensitivity, specificity and predictivity were determined for ultrasonographic findings of the endometrial cavity with the findings in the outpatient surgery program of the Servicio de Ginecologia of Hospital Mexico in 2010. The data were collected retrospectively by taking randomly a sample of the total of 147 patients with hysteroscopy. Data from selected clinical records are taken to perform statistical analysis using histories for the most frequent findings and to measure the diagnostic accuracy of both transvaginal econography and hysteroscopy. Necmar's 2x2 table is used, for to calculate the values of sensitivity, specificity, positive and negative and to obtain the comparative results. The ultrasonographic findings were: endometrial polipo 60%, endometrial thickening 20% and submucous myoma 11%. The postoperative diagnoses were: endometrial polyposis 65%, endometrial cavity without lesions 11%, submucous myoma 9%, endometrial hyperplasia 7% and endometrial atrophy 3%. Transvaginal ultrasound is proved to be an acceptable diagnostic method for endometrial polipo because it had a positive predictive value of 79%. In the submucous myoma, are found values of specificity and a very high negative predictive value, which indicates that ultrasound is actually able to rule out the presence of this pathology [es

    We wanted to describe the characteristic ultrasonography (US) features and clinical findings for making the diagnosis of subacute granulomatous thyroiditis. A total of 31 lesions from 27 patients were confirmed as subacute granulomatous thyroiditis by US-guided fine needle aspiration biopsy. We analyzed the ultrasonographic findings such as the lesion's size, margin and shape, the discrepancy between length and breadth and the vascularity. The clinical findings such as acute neck pain or fever were reviewed. The follow-up clinical and ultrasonographic data were reviewed for 15 patients. The thyroid gland was found to be enlarged in five patients, it was normal size in 20 patients and it was smaller in two patients. All the lesions had focally ill-defined hypoechogenicity. Hypervascularity was not noted in any of the lesions. Painful neck swelling was present in 18 patients. An accompanying fever was documented in nine of the 18 patients. Twelve patients showed disappearance (n = 3) or a decreased size (n = 9) of their lesions on follow-up US. The presence of ill-defined hypoechoic thyroid lesions without a discrete round or oval shape is characteristic for subacute granulomatous thyroiditis, and particularly when this is associated with painful neck swelling and/or fever

    Ultrasonographic of rabbit kidney was enformed after induction of simple and infected hydronephrosis to evaluate the sequential sonographic changes in 27 rabbits. Simple hydronephrosis was induced by ligation of the distal ureter and infected hydronephrosis by ligation of the distal ureter and ureteral inoculation of Escherichia coli. Ultrasonography was performed daily during the first week and weekly during the following 5 weeks after induction of simple and infected hydronephrosis. 1. In simple hydronephrosis, the earliest abnormal ultrasonographic finding was splitting of central renal echo complex, which appeared within 1 day after ureteral ligation in all cases. 2. In simple hydronephrosis, complete loss of central renal echo complex and cystic dilatation of pelvis were seen with in 5 days after ureteral ligation in all cases. 3. In infected hydronephrosis, the earliest abnormal ultrasonographic finding was appearance of internal echoes in dependent portion of the pelvis, which appeared within 4 days after inoculation in all cases. 4. In infected hydronephrosis, degree of internal echoes within the pelvis increased progressively with lapse of time and the entire pelvis was filled with internal echoes within 2 weeks after inoculation in all cases. 5. In infected hydronephrosis, echogenecity of internal echoes within the pelvis was similar to that of renal parenchyma in the first week after inoculation, however was weaker than that of renal parenchyma 2 weeks after inoculation in all cases

    Background/Aims To characterize ultrasonographic findings in papillary thyroid carcinoma (PTC) combined with Graves' disease. Methods Medical records and ultrasonographic findings of 1,013 patients with Graves' disease and 3,380 patients without Graves' disease were analyzed retrospectively. A diagnosis of PTC was based on a pathologic examination. Results The frequency of hypoechogenicity was lower in patients with PTC and Graves' disease than in patients with PTC alone (p Graves' disease was significantly higher than in those with PTC alone (p Graves' disease was characterized by more ill-defined borders and less frequency of overall calcification, punctate calcification, and heterogeneous echogenicity, although the difference was not statistically significant. Conclusions Our results suggest that patients with Graves' disease more frequently have atypical PTC findings on ultrasonography. PMID:20195406

    Classically air in the portal vein has been detected on plain radiography, but computed tomography and ultrasonography have been shown to be more sensitive. We report a case of air in the PV in a 10-day-old infant with pneumatosis intestinalis with its ultrasonographic and Doppler findings. The patient was a 10-day-old infant born by cesarean section at 41 weeks. Simple abdomen film revealed branching pattern of radiolucent air shadows within in contour of liver, gas distention of bowel loops and thickenod bowel walls with lincar intraluminal air shadows in abdomen, suggesting necrotizing enterocolitis. So we performed Doppler ultrasonography. Ultrasonography showed branching pattern of hyperechogenic dots and along the lumen of left portal vein. The color Doppler study revealed an aliasing duo to increased velocity and whirling pattern of blood flow, and the Duplex Doppler spectral display showed sharp, vertical bidirectional spikes by air in portal vein. Air in the portal vein can be easily diagnosed by the following signs: hyperechogenic dots in the portal vein on ultrasonography and vertical, sharp bidirectional spikes superimposed on the usual Doppler tracing of the portal vein on Duplex ultrasonography.

    Classically air in the portal vein has been detected on plain radiography, but computed tomography and ultrasonography have been shown to be more sensitive. We report a case of air in the PV in a 10-day-old infant with pneumatosis intestinalis with its ultrasonographic and Doppler findings. The patient was a 10-day-old infant born by cesarean section at 41 weeks. Simple abdomen film revealed branching pattern of radiolucent air shadows within in contour of liver, gas distention of bowel loops and thickenod bowel walls with lincar intraluminal air shadows in abdomen, suggesting necrotizing enterocolitis. So we performed Doppler ultrasonography. Ultrasonography showed branching pattern of hyperechogenic dots and along the lumen of left portal vein.

    We present the clinical results and ultrasonographic findings of 61 trigger digits treated with percutaneous A1 pulley release. An endoscopic carpal tunnel knife was used for the release in the outpatient department. The mean follow-up period was 3.5 months. A total of 55 digits (90%) had complete relief of their triggering postoperatively. Six digits (10%) had Grade 2 triggering clinically in the early postoperative period.The complications included six cases of insufficient release (10%), scar sensitivity in one patient, short-term hypoaesthesia in three digits (5%), and flexor tendon laceration noted on postoperative ultrasonography in eight digits (13%). No neurovascular damage was noted on the postoperative ultrasonography. Ultrasonograpy provides information about tendon laceration and changes in thickness of the pulleys and confirm A1 pulley release after surgery, but it does not alter clinical decision-making. We believe that pre- and postoperative ultrasonograpy does not need to be included as a routine examination. © The Author(s) 2014.

    A variety of neoplasms can develop in each tetal organ. Most fetal neoplasms can be detected by careful prenatal ultrasonographic examination. Some neoplosms show specific ultrasonographic findings suggesting the differential diagnosis, but others do not. Knowledge of the presence of a neoplasm in the fetus may alter the prenatal management of a pregnancy and the mode of delivery, and facilitates immediate postnatal treatment. During the last five years, we experienced 32 cases of fetal neoplasms in a variety of organs. We describe their typical and ultrasonographic findings with correlating postnatal CT, MRI, and pathologic findings

    Radiological and ultrasonographic studies of ten patients with surgically confirmed pancreatic pseudocysts were reviewed. All of them were male, with previous story of chronic alcoholism and clinical evidences of pancreatitis. The most important radiological finding consisted of a mass opacifying the epigastrium, displacing the stomach and bowel loops. ultrasound studies showed that the lesions were predominantly cystic, rounded or oval-shaped with smooth or irregular contours and of various sizes.

    Thirty clinical histories of patients discharged from hospital, with diagnosis of neoplasia of the pancreas, were reviewed. The patients were assisted at the ''saturnino Lora'' Teaching Provincial Hospital, Santiago de Cuba, from January 1983 to June 1985. Remarkable effectiveness of abdominal ultrasonographic study for the diagnosis of this affection was demonstrated at its correlation with other complementary examinations, such as radiographic and laparoscopic examinations, besides surgical findings and verification with histopathologic diagnosis. The tumor was more frequently located in the head of the pancreas and echogenicity and dilation of biliary and choledocus ducts were its main ultrasonographic characteristics. Adenocarcinoma was the prevailing histologic type. These findings agree with those related in the reviewed literature

    The aim of this study was to determine the normal ultrasonographic anatomy of the canine shoulder. Fourteen shoulders from 7 clinically normal mid-sized dogs were radiographed and imaged using high frequency ultrasound. Each shoulder was isolated postmortem, and the ultrasonographic and gross anatomy was studied during dissection. The ultrasonographic appearance of the shoulder specimens was similar to that found in the live dogs. Twenty-four shoulders isolated postmortem from 12 variably sized dogs were also used to characterize the normal ultrasound anatomy over a range of sizes. Important anatomic structures that could be consistently evaluated were the biceps tendon and bursa, the bicipital groove surface, the supraspinatous tendon, the infraspinatous tendon, the teres minor tendon, and the caudal aspect of the humeral head. Results of ultrasonographic examination of 4 dogs with shoulder lameness are described to illustrate some applications of canine shoulder ultrasonography in the evaluation of the canine shoulder. In these dogs, ultrasound was a valuable tool to evaluate effusion and synovial proliferation within the bicipital bursa, supraspinatous and biceps tendinitis, biceps tendon strain, and dystrophic calcification.

    To date few studies have examined whether ultrasonography can depict morphologic differences in painful and painless osteoarthritis (OA). This study describes and compares the clinical, radiographic and ultrasonographic findings of patients with both painful and painless proximal interphalgeal (PIP) and/or distal interphalgeal (DIP) OA. Patients with PIP and/or DIP OA (ACR criteria) were prospectively recruited. The clinical rheumatologist chose up to 3 painful joints and up to 3 painless symmetric joints in each patient to define 2 cohorts of OA: symptomatic (SG) and asymptomatic (ASG). A conventional postero-anterior hand x ray was performed and read by one rheumatologist following the OARSI atlas, blinded to clinical and sonographic data. Ultrasound (US) was performed by an experienced rheumatologist, blinded to both clinical and radiographic data in joints previously selected by the clinical rheumatologist. US-pathology was assessed as present or absent as defined in previous reports: osteophytes, joint space narrowing, synovitis, intra-articular power doppler signal, intra-articular bony erosion, and visualization of cartilage. Radiographic and ultrasonographic intrareader reliability test was performed. A total of 50 joints in the SG and ASG were included from 20 right handed women aged 61.85 (46-73) years with PIP and DIP OA diagnosed 6.8 (1-17) years ago. 70% SG joints and ASG were right and left sided respectively. The SG showed significantly more osteophytes, synovitis and non-visualization of joint cartilage. Intrareader radiographic and ultrasonographic agreement was excellent. This study demonstrates that painful PIP and/or DIP OA have more ultrasonographic structural changes and synovitis. Copyright © 2013 Elsevier España, S.L.U. All rights reserved.

    To evaluate the usefulness of ultrasonography in diagnosis of muscle hernia. Ultrasonographic findings of seven patients with muscle hernia were retrospectively reviewed. The subjects consisted of 6 males and 1 female, age ranged from 17 to 66 years (mean=45 years). Ultrasonographic examination was performed using a high-frequency (7-15 MHz) linear probe during rest and stress states of the affected muscle, and both tranverse and longitudinal views were obtained. Six muscle herniations were located in the lower extremity in six cases while only one muscle herniation, in the upper extremity. Four cases showed a focal defect of the fascia with a localized bulging out of the muscle substance through the defect. Herniated muscle in stress state was larger and harder than in rest state. In 3 cases, defect of the fascia was not noted on ultrasonography. However, the affected muscle showed an abnormal contraction with a focal bulging out appearance during stress state. Ultrasonographically, the herniated muscle substance was less echogenic than the normal muscle without any evidence of muscle tear or associated mass in all cases. Ultrasonography is a simple and useful dynamic study of muscle hernia in diagnosis and differentiation of muscle hernia.

    To evaluate serum feline-specific pancreatic lipase immunoreactivity (fPLI) concentrations and abdominal ultrasonographic findings in cats with trauma resulting from high-rise syndrome. Prospective case series. Animals-34 client-owned cats. From cats evaluated because of high-rise syndrome between March and October 2009, a blood sample was obtained for measurement of serum fPLI concentration within 12 hours after the fall and at 24, 48, and 72 hours after the first blood collection. Pancreatitis was diagnosed in cats with an fPLI concentration > 5.4 μg/L. Each cat had abdominal ultrasonography performed twice 48 hours apart, and pancreatic trauma was assessed via detection of pancreatic enlargement, hypoechoic or heteroechoic pancreatic parenchyma, hyperechoic mesentery, and peritoneal effusion. Cats were assigned 1 point for each abnormality present, and a cumulative score ≥ 3 was considered suggestive of traumatic pancreatitis. Traumatic pancreatitis was diagnosed in 9 and 8 cats on the basis of serum fPLI concentration and ultrasonographic findings, respectively. For cats with pancreatitis, fPLI concentration was significantly higher at 12 and 24 hours after the fall than at 48 and 72 hours after the fall, and serum fPLI concentration decreased as time after the fall increased. Significant agreement existed between the use of serum fPLI concentration and abdominal ultrasonography for the diagnosis of traumatic pancreatitis. Cats with high-rise syndrome often had serum fPLI concentrations > 5.4 μg/L within 12 hours after the fall, and concurrent evaluation of those cats via abdominal ultrasonography twice, 48 hours apart, improved detection of traumatic pancreatitis.

    In patients with lateral epicondylitis recalcitrant to nonsurgical treatments, surgical intervention is considered. Despite the numerous therapies reported, the current trend of treatment places particular emphasis on minimally invasive techniques. The authors present a newly developed minimally invasive procedure, ultrasonographically guided percutaneous radiofrequency thermal lesioning (RTL), and its clinical efficacy in treating recalcitrant lateral epicondylitis. Level of evidence, 4. Thirty-four patients (35 elbows), with a mean age of 52.1 years (range, 35-65 years), suffered from symptomatic lateral epicondylitis for more than 6 months and had exhausted nonoperative therapies. They were treated with ultrasonographically guided RTL. Patients were followed up at least 6 months by physical examination and 12 months by interview. The intensity of pain was recorded with a visual analog scale (VAS) score. The functional outcome was evaluated using grip strength, the upper limb Disability of Arm, Shoulder and Hand (QuickDASH) outcome measure, and the Modified Mayo Clinic Performance Index (MMCPI) for the elbow. The ultrasonographic findings regarding the extensor tendon origin were recorded, as were the complications. At the time of the 6-month follow-up, the average VAS score in resting (from 4.9 to 0.9), palpation (from 7.6 to 2.5), and grip (from 8.2 to 2.9) had improved significantly compared with the preoperative condition (P lateral epicondylitis was found to be a minimally invasive treatment with satisfactory results in this pilot investigation. This innovative method can be considered as an alternative treatment of recalcitrant lateral epicondylitis before further surgical intervention.

    Sparganosis of the breast is a quite rare parasitic infection of humans and presents as soft tissue masses that mimic breast malignancy or benign tumor, such as fibroadenoma. We present here a case of histologically confirmed breast sparganosis in the upper inner quadrant of the right breast with coexisting breast cancer in the ipsilateral breast upper outer quadrant. Ultrasonography of breast sparganosis showed a well defined, tubular hypoechoic mass with discrete multilayered wall and tubule-in tubule appearance, surrounded by heterogenous hyperechoic areas in the subcutaneous fat layer of the breast. MRI revealed an elongated tubular structure with persistent and progressive enhancement. This is the second report concerned with the MRI and ultrasonographic findings of breast sparganosis and the first report of breast sparganosis in a patient with ipsilateral breast cancer

    The aim of our study is to assess the efficiency of the ultrasonography (US) in the diagnosis of peripheral nerve injury. This study includes nine patients (six radial, one median and two posterior interosseous (PIO) nerves) with peripheral nerve injury diagnosed by clinical and electrophysiological methods in the last 3 years. Preoperatively, an ultrasonographic examination was performed and correlated with physical exam and surgical findings. Five patients, who were diagnosed as peripheral nerve transection by US, underwent surgery. The ultrasonographic findings were concordant with the intraoperative findings. Axonal swelling alone was found in the remaining three patients, who were treated conservatively because of preserved nerve continuity without display of nerve compression. In one patient, we were unable to visualize the nerve due to obesity and soft tissue edema. High-resolution US provide morphological information about the exact location, intensity and extent of the nerve injuries, facilitating the preoperative diagnosis. Thus, US may be a useful method for planning optimal treatment strategy in especially iatrogenic nerve injuries.

    Captive leopard geckos (Eublepharis macularius) often present to the exotic clinic for gastrointestinal impactions, follicular stasis, or dystocia. To our knowledge, normal ultrasonographic anatomy of these lizards has not been described. The objectives of this prospective, anatomic, analytical study were to develop ultrasound techniques for this species and to describe the normal sonographic anatomy of the head, coelomic cavity, and tail. Eleven, healthy, female leopard geckos were included. A linear array 13-18 MHz transducer was used. Geckos were sedated and restrained in dorsal recumbency for coelomic structure examination and in ventral recumbency for head and tail examinations. Sagittal and transverse images were acquired and authors recorded qualitative and quantitative ultrasonographic characteristics of anatomic structures. The ventral surface of the lungs, liver, gallbladder, caudal vena cava, portal vein, ventral abdominal vein, aorta, ovarian follicles, fat bodies, tail, and brain were visualized in 10 of 11 individuals. In one individual, molt precluded ultrasonographic examination. The heart, kidneys, urinary bladder, spleen, and pancreas were not visualized. The digestive tract was observed in 10 individuals but was too small to be measured. Findings from the current study could be used as a reference for future studies of leopard geckos. © 2018 American College of Veterinary Radiology.

    To characterize the ultrasonographic findings of multicystic dysplastic kidney on prenatal ultrasonography (US) with a special emphasis on the distribution of cysts. From January 1998 to March 2003, medical records of sixty two subjects with multicystic dysplastic kidney diagnosed on prenatal US examination were retrospectively reviewed, and forty three patients confirmed either by pathology or postnatal follow-up US were selected for this study. US assessment included the time of diagnosis, laterality, size of the multicystic dysplastic and contralateral normal kidneys, distribution of cysts and associated anomalies. The distribution of cysts was categorized as subcapsular and random distribution, and interobserver agreement was determined using the cross table analysis. The largest multicystic and contralateral normal longitudinal diameters were measured, and the data were plotted on the normal reference chart. Multicystic dysplastic kidney was left sided in 55.8%, right sided in 34.8% and bilateral in 9.3%. Subcapsular distribution of cysts was observed in 68.2% (n=15) for radiologist 1 while 59.1% (n=13) for radiologist 2, showing an excellent interobserver agreement (k=0.697). The longitudinal diameter of the multicystic dysplastic kidney was above 95 percentile in 68%. Meanwhile, the diameter of the contralateral normal kidney was more commonly normal, 70%. Fetal karyotyping was done in 18 cases including 2 cases with associated major anomalies, but karyotyping was all normal. On prenatal US, subcapsular distribution of cysts in multicystic dysplastic kidney is more common than random distribution. This characteristic distribution of cysts may be helpful in the prenatal diagnosis of multicystic dysplastic kidney.

    Adenocarcinoma, followed by lymphosarcoma, are the most common feline intestinal neoplasms. Clinicopathological, survey radiographic, and ultrasonographic findings of five cats with intestinal adenocarcinoma are reported. An abdominal mass was palpable in all five cats, but the mass could be localized to bowel in only two cats. Radiographically an abdominal mass was detected in only one cat. Ultrasonographically there was a segmental intestinal mural mass in all five cats. The mass was characterized by circumferential bowel wall thickening with transmural loss of normal sonographic wall layers. In one cat, the circumferential symmetric hypoechoic bowel wall thickening was similar to that reported for segmental lymphoma. In the other four cats, the sonographic features of the thickened bowel wall were varied, being mixed echogenicity and asymmetric in 3 cats and mixed echogenicity and symmetric in one. The results of the present report suggest that sonographic observation of mixed echogenicity segmental intestinal wall thickening in the cat represents adenocarcinoma rather than lymphosarcoma, although other infiltrative diseases should be considered

    Aissi

    Full Text Available The aim of the present study was to follow up the potential of routine ultrasonographic diagnostics of pregnancy in bitches depending on the first mating. The experiments were performed on 32 bitches. Pregnancy was detected using transabdominal ultrasonography with Siemens sonoline adara equipment and a covex 5 MHz probe. Subsequent serial examinations were made to sonographically characterize normal canine prenatal development based about the first mating. An enlarged uterus, gestational sacs and fetal poles were recognized as the features of early bitchs pregnancy and were first seen at 16 and 21 days, respectively. Cardiac activity was detected earliest on gestational day 22 and recognizable canine fetal morphology appeared at day 28. Generalized fetal movements were first noted at day 28.

    Intestinal tuberculosis is generally diagnosed using conventional barium studies, however recent diagnostic modalities such as ultrasonography and CT scan are widely applicated in conjunction with conventional studies for the search of lymph node presentation and associated extra-intestinal organs. It is important to differentiate intra-abdominal tuberculosis from metastatic or lymphomatous disease clinically. And it might be especially of worth to find out if there is any differential point between tuberculosis and other lymph nodal disease entities when we meet similar findings on imaging modalities. Authors have tried to evaluate ultrasonographic findings in conjunction with other studies in nine cases of abdominal tuberculosis which showed mainly extra-intestinal and/or lymph nodal involvement

    Real-time ultrasonography is a simple, accurate, noninvasive and potentially valuable means of studying gallbladder size and emptying. The authors calculated ultrasonographically the ejection fraction of 80 cases of normally functioning gallbladder on oral cholecystography, from June 1983 to April 1984, at the department of radiology, Hangang Sacred Heart Hospital. The results were obtained as follows; 1. Ultrasonographic Ejection Fraction at 30 minutes after the fatty meal was 73.1{+-}16.85. 2. There was no significant difference in age and sex, statistically.

    The prostate commonly develops benign prostatic hyperplasia (BPH) in dogs over 5 years, while in aged dogs other pathological findings might be revealed by ultrasonographic exam. The aim of the present study was to estimate the most suitable age for a preventive ultrasonographic examination of the prostate in the dog. The prostate of 1003 intact male dogs of 64 different breeds, of different ages (1-18 years) and bodyweights (2-55 kg) was evaluated with ultrasound, irrespective of the reason for clinical examination. The age of each dog was expressed as the ratio between the actual age and the maximum longevity expected for the breed. Dogs were divided in two groups based on breeds' life expectancy as short life (SL) and long life (LL). The size of the prostate (normal, enlarged or small) and the presence of abnormal sonographic findings were recorded for each dog. The results of the present study indicate that the most suitable age for a preventive ultrasonographic exam of the prostate in the dog is approximately at 40% of its expected longevity, both in short and long life breeds, because at this age there is a strong possibility to be able to detect abnormal prostatic findings. In 47.5% of the dogs at least one abnormal finding of the prostate was revealed by ultrasonographic exam, while dogs with long life expectancy showed a significantly higher prevalence of abnormalities, than dogs with short life expectancy. The most frequent findings were the increase of prostatic size (33.5%) and the presence of at least one cyst (33.6%), with no difference between SL and LL dogs. In conclusion, a preventive examination of the prostate starting at 40% of expected longevity in dogs of short and long life breeds is strongly recommended for early detection of abnormalities, for scheduling specific follow up and for suggesting effective therapeutic protocols.

    The Korean Thyroid Association recommends fine-needle aspiration biopsy (FNAB) for nodules more than 0.5 cm in diameter. But nodules, smaller than 0.5 cm have been found in papillary carcinomas of the thyroid (PTC) at the health promotion center at SMC. We wanted to evaluate the ultrasonographic findings according to size of nodule in proven PTCs by FNAB, especially less than 0.5 cm. All nodules were classified into three groups by their longest diameter : less than 0.5 cm, more than 0.5 cm but less than 1 cm, and more than 1 cm. Sonographic findings suggesting malignancy were analyzed according to their size groups. Of 288 malignant nodules, 21.5 % (62/288) were less than 0.5 cm , 54.9 % (158/288) were more than 0.5 cm but less than 1 cm, 23.6 % (68/288) exceeded 1 cm. A taller-than-wide shape was observed in 90.3 % (56/62) of nodules less than 0.5 cm, and 48.5 % (33/68) of nodules exceeding 1 cm (p<0.001). There were no well-defined smooth nodules among nodules less than 0.5 cm, and spiculated or irregular margin nodules increased as the size increased (p=0.024). Nodules of size less than 0.5 cm did not showed hyper or isoechogenicity. Hypoechogenicity was greater than the marked hypoechogenicity in each group (p=0.034). Micro- or macro-calcifications were not founded in 77.4 % (48/62) of the nodule group sized less than 0.5 cm. From the small size of the group, micro- or macrocalcifications were observed 21.0 % (13/62), 48.1 % (76/158), 64.7 % (44/68), so the number of nodules containing micro- or macro-calcification increased as size increased (p<0.001). PTCs less than 0.5 cm in size on ultrasonography had taller than-wide shape, spiculated or irregular and ill-defined margins, and exhibited hypo and markedly hypoechogenicity, but microor macro-calcifications were not common. These ultrasonographic features of nodules less than 0.5 cm can be useful in reporting and guiding FNABs or follow-up exams.

    Differential diagnoses for regurgitation and vomiting in dogs include diseases of the gastroesophageal junction. The purpose of this cross-sectional study was to describe ultrasonographic characteristics of the abdominal esophagus and gastric cardia in normal dogs and dogs with clinical disease involving this region. A total of 126 dogs with no clinical signs of gastrointestinal disease and six dogs with clinical diseases involving the gastroesophageal junction were included. For seven euthanized dogs, ultrasonographic features were also compared with gross pathology and histopathology. Cardial and abdominal esophageal wall thicknesses were measured ultrasonographically for all normal dogs and effects of weight, sex, age, and stomach filling were tested. Five layers could be identified in normal esophageal and cardial walls. The inner esophageal layer was echogenic, corresponding to the cornified mucosa and glandular portion of the submucosa. The cardia was characterized by a thick muscularis, and a transitional zone between echogenic esophageal and hypoechoic gastric mucosal layers. Mean (±SD) cardial wall thicknesses for normal dogs were 7.6 mm (±1.6), 9.7 mm (±1.8), 10.8 mm (±1.6), 13.3 mm (±2.5) for dogs in the dog weight group. Ultrasonography assisted diagnosis in all six clinically affected dogs. Findings supported the use of transabdominal ultrasonography as a diagnostic test for dogs with suspected gastroesophageal disease. © 2014 American College of Veterinary Radiology.

    The aim of this study was to evaluate the prevalence of upper-body-quadrant pain among ultrasonographers and to evaluate the association between individual ergonomics, musculoskeletal disorders, and occurrence of neck pain. A hundred and ten (N = 110) Belgian and Dutch male and female hospital ultrasonographers were consecutively enrolled in the study. Data on work-related ergonomic and musculoskeletal disorders were collected with an electronic inquiry, including questions regarding ergonomics (position of the screen, high-low table, and ergonomic chair), symptoms (neck pain, upper-limb pain), and work-related factors (consecutive working hours a day, average working hours a week). Subjects with the screen on their left had significantly more neck pain (odds ratio [OR] = 3.6, p = .0286). Depending on the workspace, high-low tables increased the chance of developing neck pain (OR = 12.9, p = .0246). A screen at eye level caused less neck pain (OR = .22, p = .0610). Employees with a fixed working space were less susceptible to arm pain (OR = 0.13, p = .0058). The prevalence of arm pain was significantly higher for the vascular department compared to radiology, urology, and gynecology departments (OR = 9.2, p = .0278). Regarding prevention of upper-limb pain in ultrasonograph, more attention should be paid to the work environment and more specialty to the ultrasound workstation layout. Primary ergonomic prevention could provide a painless work situation for the ultrasonographer. Further research on the ergonomic conditions of ultrasonography is necessary to develop ergonomic solutions in the work environment that will help to alleviate neck and arm pain. © 2014, Human Factors and Ergonomics Society.

    To determine the ultrasonographic findings and assess the usefulness of ultrasound (US)-guided biopsy of central lung tumors in patients with obstructive pneumonitis. Fourteen patients with central lung tumors causing obstructive pneumonitis, as seen on chest radiographs and chest CT scans, were examined between January 1997 and January 2000. In no patient conclusive histologic diagnosis obtained by means of bronchoscopic biopsy or sputum cytology. Eleven patients were men and three were women, and their ages ranged from 45 to 83 (mean, 64) years. For all examinations, real-time, linear-array, convex US units with a 3.75-and a 5.0-MHz transducer were used. The images obtained were analyzed for evidence of consolidation or atelectasis in the lung, demonstrable tumors, and tumor size and echogenicity. For US-guided percutaneous transthoracic biopsy, 19.5G automatic biopsy devices, were employed. Lung consolidation due to a wedge-shaped, homogeneous, hypoechoic lesion was revealed by sonographic fluid bronchograms, air bronchograms, air alvelograms, and visualization of intraparenchymal pulmonary vessels, which showed appropriate motion with respiration. The tumor presumed to be causing obstruction was seen as a hypoechoic nodule near the hilum or as a well-defined hyperechoic mass inside the partially consolidated lung. Pleural effusion was observed in one case. The cytologic findings indicated the presence of squamous cell carcinoma (n=4), adenocarcinoma (n=4), small cell carcinoma (n=3), non-small cell carcinoma (n=2) and large cell carcinoma (n=1). The success rate was 100%, and there were no complications. In patients with central lung tumors causing obstructive pneumonitis, chest ultrasonography and US-guided biopsy are useful adjunctive diagnostic modalities and techniques.

    The purpose of this study was to describe the ultrasonographic (US) and mammographic (MX) findings in patients who underwent breast-conserving surgery followed by oxidized regenerated cellulose (ORC) implantation in the surgical cavity and their size variations in follow-up. We retrospectively reviewed 417 MX and 743 US images performed between January 2009 and January 2014 for 262 women who underwent breast-conserving surgery. All patients underwent US, only 203 women underwent MX examination. In 170 of 262 patients, US examinations showed abnormal findings. Three main US patterns were identified: (1) complex masses: well-encapsulated ipoisoechoic lesions with circumscribed margins with internal hyperechoic nodules (56%); (2) hypoanechoic lesions without internal hyperechoic nodules (24%); and (3) completely anechoic collections (20%). Moreover, Doppler ultrasound examination was performed on all of the patients. In 95 of 203 patients, MX examinations showed abnormalities. Four main MX patterns were identified: (1) round or oval opacity with circumscribed margins (58%); (2) round or oval opacity with indistinct or ill-defined margins (17%); (3) irregular opacity with indistinct or spiculated margins (9%); and (4) architectural distortion or focal asymmetry (15%). Most of the lesions showed a decrease in size at US and MX follow-up examination and the decrease was statistically significant (P < .01). When applied to the surgical residual cavity, ORC aids to control local hemorrhage and reduce the risk of postoperative infections, but can lead to alterations in surgical scar. Thus, knowledge of the radiological findings might allow avoidance of misdiagnosis of tumor recurrence or unnecessary diagnostic examinations. Copyright © 2015 Elsevier Inc. All rights reserved.

    Although ultrasonographic evaluation of the normal ureters is difficult due to bowel gas, the lower segment of the normal ureters can be visualized using the urinary bladder as an acoustic window. Authors prospetively performed ultrasonography with the standard suprapubic technique and analyzed the ultrasonographic features of normal lower ureters in 79 cases(77%). Length of visualized segment of the distal ureter ranged frp, 1.5cm to 7.2 cm and the visualized segment did not exceed 3.9mm in maximum diameter. Knowledge of sonographic features of the normal lower ureters can be helpful in the evaluation of pathologic or suspected pathologic conditions of the lower ureters

    The objectives of this study were to assess the ultrasonographic (US) findings in patients with knee osteoarthritis (OA) with pes anserinus tendinitis or bursitis (PATB) syndrome and to determine the correlation between the US findings and the response to local corticosteroid injection. We prospectively studied 26 patients with knee OA with clinically diagnosed PATB syndrome. A linear array 7 MHz transducer was used for US examination of the knee. Seventeen patients were injected locally with tramcinolone acetonide in the anserine bursa area. Response to local corticosteroid injection was evaluated by pain visual analog scale (VAS), Western Ontario and MacMaster (WOMAC) osteoarthritis index and Global patient/physician assessment using Likert scale. On US examination, only 2 patients (8.7%) showed evidence of PATB. Pain VAS, WOMAC pain index and WOMAC physical function index improved significantly after corticosteroid injection. Global patient assessment revealed that 2 patients showed best response, 6 good, 1 fair, 8 the same, and none worse. It is of note that the 2 patients who showed the best response were those who showed US evidence of PATB. This finding shows that US can serve as a useful diagnostic tool for guiding treatment in PATB syndrome of OA patients.

    We review here 3 cases of primary thyroid lymphoma that we experienced during the past 5 years (age range: 39-55, all of the patients were female). The clinical and various ultrasonographic characteristics together with the other imaging modalities of primary thyroid lymphomas are described. The clinical features at presentation for one patient were a goiter with rapid growth and this was accompanied by compressive symptoms. The tumors of the other 2 patients were incidentally found during screening thyroid ultrasound exams. The pathologic studies of 2 cases showed a diffuse B-cell lymphoma with associated Hashimoto's thyroiditis and one case was a B-cell lymphoma of the MALT type. An extra-thyroid extension was shown in one case. The treatments included surgery alone for two cases, and chemotherapy and radiation therapy for one case. A US exam of thyroid lymphoma can show various morphological features, and US-CNB is helpful for diagnosing thyroid lymphoma.

    Although serial killings are relatively rare, they can be the cause of a great deal of anxiety while the killer remains at-large. Despite the fact that the motivations for serial killings are typically quite complex, the psychological analysis of a serial killer can provide valuable insight into how and why certain individuals become serial killers. Such knowledge may be instrumental in preventing future serial killings or in solving ongoing cases. In certain serial killings, the various incidents have a variety of similar features. Identification of similarities between separate homicidal incidents is necessary to recognize that a serial killer may be actively killing. In this report, the authors present a group of serial killings involving three prostitutes who were shot to death over a 3-month period. Scene and autopsy findings, including the unusual finding of postmortem enucleation of the eyes, led investigators to recognize the serial nature of the homicides. © 2015 American Academy of Forensic Sciences.

  1. Serial position markers in space: visuospatial priming of serial order working memory retrieval.

    Directory of Open Access Journals (Sweden)

    Maya De Belder

    Full Text Available Most general theories on serial order working memory (WM assume the existence of position markers that are bound to the to-be-remembered items to keep track of the serial order. So far, the exact cognitive/neural characteristics of these markers have remained largely underspecified, while direct empirical evidence for their existence is mostly lacking. In the current study we demonstrate that retrieval from verbal serial order WM can be facilitated or hindered by spatial cuing: begin elements of a verbal WM sequence are retrieved faster after cuing the left side of space, while end elements are retrieved faster after cuing the right side of space. In direct complement to our previous work--where we showed the reversed impact of WM retrieval on spatial processing--we argue that the current findings provide us with a crucial piece of evidence suggesting a direct and functional involvement of space in verbal serial order WM. We outline the idea that serial order in verbal WM is coded within a spatial coordinate system with spatial attention being involved when searching through WM, and we discuss how this account can explain several hallmark observations related to serial order WM.

    The authors analyzed ultrasonographically the total 45 cases of thyroid disease verified by historical diagnosis, functional diagnosis, and morphological diagnosis at the Department of Radiology, Busan National University Hospital from June to September 1982. The results obtained were as follows: 1. In the sex distribution female was 38 cases (84.4%), and male 7 cases (15.6%). The second, third, and fourth decades of age (78.0%) were most prevalent. 2. Among the total 45 cases thyroid adenoma was 24 cases (53.3%), nodular hyperplasia cases (17.7%), thyroid carcinoma 7 cases (15.6%), diffuse hyperplsia 3 cases (6.7%), Hashimoto's thyroiditis 1 cases (2.2%), subacute thyroiditis 1 cases (2.2%), tuberculous thyroiditis 1 case (2.2%) in orders. 3. On ultrasonogram, total 24 cases of thyroid adenoma showed a single nodule in 24 cases (100.0%), smooth outer margin in 23 cases (95.8%), capsular echo in 23 cases (95.8%), pure cystic nodule in 4 cases (16.7%), and increased echogenicity in 17 cases (85.0%) among the 20 cases exclude that pure cystic nodules. 4. Total 7 cases of thyroid carcinoma showed no capsular echo in 4 cases (57.1%), irregular outer margin in 4 case (57.1%), no pure cystic nodule in all cases, and enlargement of metastatic lymphnode in 4 cases (57.1%). 5. Total 8 cases of nodular hyperplasia showed enlargement of thyroid gland and multiple nodule in 8 cases (100.0%), and increased echogenicity in 7 cases (87.5%). 6. Total 3 cases of diffuse hyperplasia showed enlargement of thyroid gland and increased echogenicity in 3 cases (100.0%). 7. Total 3 cases of thyroiditis showed decreased echogenicity in 3 cases (100.0%) and enlargement of thyroid gland in 2 cases (66.7%). 8. The cold area visualized on radionuclide scan could be differentiated from a solid mass and cystic one by ultrasonogram.

    The purpose of this study was to describe the ultrasonographic features and assess the diagnostic value of sonography in the evaluation of children with Henoch-Schonlein purpura. Between October 1993, and Febuary 1998, 67 children with Henoch-Schonlein purpura underwent abdominal ultrasonography, which in 13 was used for follow up. Bowel wall thickness and location, pattern of color Doppler signal in the thickened bowel wall, the size and location of enlarged mesenteric lymph node and the presence of ascites were evaluated. In 42 cases(63%), sonographic findings were positive, and indicated mesenteric lymphadenopathy(n=3D21), small bowel wall thickening(n=3D20), and ascites(n=3D17). Thickened bowels were demonstrated at the ileum in 11 cases, the jejunum in five, the duodenum in one, and combined wall thickening at the duodenum and jejunum in two;thickening of the duodenum and ileum was seen in one case. Thickness varied from 3 to 10 mm(mean:6.5 mm). On follow-up sonography, regression of bowel wall thickening was observed earlier than that of mesenteric lymphadenopathy or ascites, and correlated well with improved abdominal symptoms. Abdominal ultrasonographic manifestations of Henoch-Schonlein purpura were bowel wall thickening, mesentric lymphadenopathy and ascites. Sonography was a simple and useful method for the evaluation of gastrointestinal manifestation of Henoch-Schonlein purpura.=20

    The aims of the study were to detect the frequency of involvement of the Achilles tendon and plantar fascia in patients with calcium pyrophosphate deposition disease (CPPD) by high-frequency gray-scale ultrasonography (US) and power Doppler sonography (PDS) and to correlate these findings with demographic and clinical data. Two groups of patients were enrolled: group I (38 patients with CPPD) and group II (22 patients with knee OA). US/PDS examination of the heels was performed to both groups. In the CPPD group, US/PDS examination of the Achilles tendon revealed: calcification in 57.9%, enthesophytosis in 57.9%, enthesopathy in 23.7%, vascular sign in 21%, bursitis in 13.2%, and cortical bone irregularity in 10.5%. US/PDS examination of plantar fascia in the CPPD group revealed: calcification in 15.8%, cortical bone irregularity in 78.9%, enthesophytosis in 60.5%, and planter fasciitis in 42.1%. In patients with CPPD, age was significantly correlated with enthesophytosis and deep retrocalcaneal bursitis (p = 0.01 and p = 0.04, respectively). Heel tenderness and posterior talalgia were significantly correlated with Achilles tendon enthesopathy, vascular sign, and deep retrocalcaneal bursitis (p = 0.0001 for each). Inferior talalgia was significantly correlated with plantar fasciitis (p = 0.0001). The sensitivity of ultrasonography for detection of calcifications in Achilles tendon and plantar fascia was 57.9% and 15.8%, respectively, and the specificity was 100% for both. To conclude, ultrasonographic Achilles tendon and plantar fascia calcifications are frequent findings in patients with CPPD. These calcifications have a high specificity and can be used as a useful indirect sign of CPPD.

    Full Text Available Aim: This study was designed for clinical and laboratory evaluation of intestinal obstruction (IO in buffaloes (Bubalus bubalis with special emphasis on the diagnostic value of ultrasonographic findings. Materials and Methods: A total number of 30 buffaloes were included in the study and divided into 2 groups: Healthy (n=10 and diseased group (n=20. Diseased buffaloes were admitted to the Veterinary Teaching Hospital at Assiut University, Egypt, with a history of anorexia, abdominal pain, various degrees of abdominal distention, and absence or presence of scanty mucoid faces. These animals were subjected to clinical and ultrasonographic as well as laboratory examinations. Results: Based on ultrasonographic findings, various forms of IO were diagnosed. Functional obstruction, paralytic ileus, was diagnosed in 17 cases (85% while mechanical IO was diagnosed only in 3 cases (15%. Out of 17 cases of paralytic ileus, both proximal and distal ileuses were successfully imaged in 8 and 9 cases, respectively. Proximal ileus was imaged from the right dorsal flank region as a single dilated loop of diameter >6 cm, while distal ileus was imaged as multiple dilated loops of diameter <6 cm. Mechanical obstruction due to duodenal intussusception was visualized as two concentric rings with outer echogenic wall and hypoechoic lumen. All cases of IO showed leukocytosis, hypoproteinemia, and increased activity of alkaline phosphatase and aspartate aminotransferase. Conclusion: Ultrasonography proved to be an essential tool for diagnosis and differential diagnosis of various forms of IO in buffaloes.

    Objectives The present study was designed to gain information about the ultrasonographic features of livers with cystic echinococcosis, as well as to evaluate the use of ultrasonography for diagnosis of such disease in sheep. Design This was a retrospective study during the period April 2011 to March 2013. Participants A total of 22 Baladi sheep (aged three to six years) were included in this study. Based on clear hepatic ultrasonographic findings, all animals were classified into two groups: those with hepatic cysts (n=9) and without liver cysts (healthy liver, n=13). Results Biochemically, serum concentrations of γ-glutamyl transferase, aspartate aminotransferase, total bilirubin and globulins were significantly increased (P<0.01), while albumin was lowered (P<0.01) in sheep with cystic livers. Ultrasonographic findings of diseased sheep livers revealed the presence of rounded, anechoic and unilocular hydatid cysts with ellipse circumference ranged from 6–10 cm. The borders of cysts were mostly well defined. The interior of cysts contained echogenic particulate materials, septations, or fine echoes. At the 10th intercostal space, the ventral margin, size, thickness and angle of livers were higher (P<0.01), while the diameter of portal vein was lower (P<0.01) in sheep with liver cysts than control ones. Furthermore, at the 9th intercostal space, the circumference of the gall bladder was decreased in sheep with hepatic cysts (P<0.01). The sensitivity, specificity, and positive and negative predictive values of ultrasonography for diagnosis of hepatic hydatid cysts were 80 per cent and 100 per cent, and 100 per cent and 83 per cent, respectively. Conclusions Cystic echinococcosis is associated with a number of anatomical alterations in the liver tissues that can be easily recognised by ultrasound. Furthermore, ultrasonography alone or in combination with analysis of biochemical parameters reflecting liver function could be helpful for diagnosis of hepatic

    The prognosis of osteoporotic vertebral fractures in the thoracic and lumbar spine was studied by serial MRI findings. This study covered 80 vertebrae in 69 patients treated conservatively and followed-up for more than six months (23 males and 46 females, average age 70 yrs). Group A, characterized by poor diagnostic imaging, consisted of patients who had both severely collapsed vertebra which was progressive in the lateral roentgenogram and delayed improvement in MRI signal intensities. Group B, consisting of poor clinical prognosis, comprised patients with persistent back pain. The predictive factors for Group A were found to be T 1 -low finding over the entire vertebra within one month after injury and fractures of Th 12 or L 1 vertebra. Areas of T 1 -low and T 2 -low intensity adjacent to the vertebral disc presented no improvement in signal intensity and often caused persistent back pain. (author)

    We wanted to retrospectively determine the accuracy of an ultrasonographic diagnosis of superficial soft tissue masses in the extremities by using the histologic results as the reference standard. From January 2005 to June 2010, 154 patients with soft tissue masses in the extremities and who underwent ultrasonographic evaluation followed by biopsy or resection were retrospectively evaluated. The ultrasonographic and histologic diagnoses of the soft tissue masses were lipoma, ganglion cyst, hemangioma, neurogenic tumor, giant cell tumor of the tendon sheath, epidermoid cyst, fibroma, glomus tumor, Baker's cyst and neurofibromatosis. Out of 154 patients, 114 (74%) patients showed concordance between the histologic diagnosis and the ultrasonographic diagnosis, and the remaining 40 (26%) patients did not. The diagnostic accuracy of each soft tissue mass was 95% for lipoma, 83% for ganglion cyst, 75% for hemangioma, 72% for neurogenic tumor, 50% for giant cell tumor of the tendon sheath, 43% for epidermoid cyst, 33% for fibroma and 100% each for glomus tumor, fibromatosis and Baker's cyst. Aside from these tumors, there were also sarcoma, malignant melanoma, elastofibroma, Kimura disease and pilomatricoma. Among the cases that showed discordance between the histologic diagnosis and the ultrasonographic diagnosis, three of them were notable; pilomatricoma being misdiagnosed as dermatofibroma protuberans, angiolipoma being misdiagnosed as vascular leiomyoma and malignant fibrous histiocytoma being misdiagnosed as a malignant soft tissue mass. The accuracy of an ultrasonographic diagnosis for soft tissue masses in the extremities varies greatly according to each type of mass. Lipoma, ganglion cyst, hemangioma, glomus tumor, neurogenic tumor and Baker's cyst showed a relatively high rate of concordance between the ultrasonographic diagnosis and the histologic diagnosis, but epidermoid cyst and fibroma showed a relatively lower rate of concordance

    Anal ultrasound is helpful in assessing organic anorectal lesions, but its role in functional disease is still questionable. The purpose of the present study is to assess anal-vaginal-dynamic perineal ultrasonographic findings in patients with obstructed defecation (OD) and healthy controls. Ninety-two consecutive patients (77 women; mean age 51 years; range 21-71) with symptoms of OD were retrospectively evaluated. All patients underwent digital exploration, endoanal and endovaginal ultrasound (US) with rotating probe. Forty-one patients underwent dynamic perineal US with linear probe. Anal manometry and defaecography were performed in 73 and 43 patients, respectively. Ultrasonographic findings of 92 patients with symptoms of OD were compared to 22 healthy controls. Anismus was defined on US when the difference in millimetres between the distance of the inner edge of the puborectalis muscle posteriorly and the probe at rest and on straining was less then 5 mm. Sensitivity and specificity were calculated by assuming defaecography as the gold standard for intussusception and rectocele and proctoscopy for rectal internal mucosal prolapse. Since no gold standard for the diagnosis of anismus was available in the literature, the agreement between anal US and all other diagnostic procedures was evaluated. The incidence of anismus resulted significantly higher (P anismus, anal ultrasonography resulted in agreement with perineal and vaginal US, manometry, defaecography, and digital exam (P < 0.05). Other lesions detected by US in patients with OD include solitary rectal ulcer, rectocele and enterocele. Damage of internal and/or external sphincter was diagnosed at anal US in 19/92 (20%) patients, all continent and with normal manometric values. Anal, vaginal and dynamic perineal ultrasonography can diagnose or confirm many of the abnormalities seen in patients with OD. The value of the information obtained by this non-invasive test and its role in the diagnostic algorithm

    Five female egg-laying pigeons presented with painless, reducible, ventral abdominal swellings located between the keel and the pubis, or close to the cloaca. Based on clinical, radiographic, and ultrasonographic examination, these pigeons were diagnosed with ventral abdominal hernia requiring surgical interference. Reduction was successfully performed under general anesthesia. Radiographic and ultrasonographic examinations were beneficial for confirming the diagnosis and visualizing the hernial content for surgical planning. Lateral radiographs were more helpful than ventrodorsal radiographs for identification of the hernial content and its continuation with the abdominal muscles. Ultrasonographic examination offered a non-invasive diagnostic tool that allowed for the differentiation of hernia from other abdominal swellings. In addition, it played a beneficial role in identification of the hernial content and follow up after surgical interference. In conclusion, radiographic and ultrasonographic examinations were beneficial in the diagnosis, surgical planning, and follow up after surgical interference of ventral abdominal hernia in pigeons.

    The prognosis of osteoporotic vertebral fractures in the thoracic and lumbar spine was studied by serial MRI findings. This study covered 80 vertebrae in 69 patients treated conservatively and followed-up for more than six months (23 males and 46 females, average age 70 yrs). Group A, characterized by poor diagnostic imaging, consisted of patients who had both severely collapsed vertebra which was progressive in the lateral roentgenogram and delayed improvement in MRI signal intensities. Group B, consisting of poor clinical prognosis, comprised patients with persistent back pain. The predictive factors for Group A were found to be T{sub 1}-low finding over the entire vertebra within one month after injury and fractures of Th{sub 12} or L{sub 1} vertebra. Areas of T{sub 1}-low and T{sub 2}-low intensity adjacent to the vertebral disc presented no improvement in signal intensity and often caused persistent back pain. (author)

    Rasmussen's syndrome is characterized by intractable seizures and progressive neuropsychiatric deterioration secondary to unilateral cortical inflammation and tissue destruction. Diagnosis of Rasmussen's syndrome in the early phase depends mainly on the clinical features. Neuroimaging and histopathologic examinations may not be specific during this period. We report a case of Rasmussen's syndrome followed by serial MRI and magnetic resonance spectroscopy (MRS) studies over a 3- to 16-month period. A healthy 6-year-old boy presented with focal motor seizures. An MRI study demonstrated prominent enlargement and T2 hyperintensity of the left mesial temporal lobe and perisylvian region. This early finding evolved to volume loss and later progressive atrophy of the ipsilateral hemisphere when epilepsia partialis continua occurred. Being aware of those early MRI features in a patient with increasing frequency of focal motor seizures should suggest Rasmussen's syndrome. In addition, we found prominently increased myoinositol concentration in atrophic cortex which might reflect increased gliosis in the late period of the disease. (orig.)

    Purpose: To describe and quantitate the radiological (mammographic and ultrasonographic) characteristics of male breast disease and to report the clinical and pathological findings. Materials and methods: Two-hundred-thirty-six male patients with different male breast diseases, diagnosed at our institution between January 1990 and July 2001, were retrospectively evaluated. The history, physical examination, mammographic and ultrasonographic findings were analyzed. Results: The spectrum of the disease in 236 male patients were gynecomastia (n=206), primary breast carcinoma (n=14), fat necrosis (n=5), lipoma (n=3), subareolar abscess (n=2), epidermal inclusion cyst (n=1), sebaceous cyst (n=1), hematoma (n=1), myeloma (n=1), and metastatic carcinoma (n=2). The distribution of patterns of gynecomastia were; 34% (n=71) nodular, 35% (n=73) dendritic and 31% (n=62) diffuse glandular. Gynecomastia was unilateral in 55% (n=113) and bilateral in 45% (n=93) of the patients. Male breast cancer presented as a mass without microcalcifications in 86% (n=12) and with microcalcifications in 7% (n=1) of patients. The mass was obscured by gynecomastia, partially in two, totally in one patient. The location of the mass was retroareolar in 46% (n=6) and eccentric to the nipple in 54% (n=7) of patients. On ultrasonography (US), the contours were well-circumscribed in 20% (n=3) and irregular in 80% (n=12) of the masses. Conclusion: Male breast has a wide spectrum of diseases, some of which have characteristic radiological appearances that can be correlated with their pathologic diagnosis. In the evaluation of the male breast, mammography and US are essential and should be performed along with physical examination

    Hypertrophic fellne musculer dystrophy has been reported as an X-linked inherited deficiency of a cytoskeletal myofiber protein called dystrophin. This report deserlbes the radiographic and ultrasonographic abnormalities of two male littermate domestic short-hair cats and reviews the previous reported findings assoclated with hypertrophic feline muscular dystrophy. The thoracic radiographic abnormalities included: progressive cardiomegaly, large convex, scalloped irregularities associated with the vetral aspect of the diaphragm, and variable degrees of esophageal dilation (megaesophagus) with associated cranioventral aspiration pneumonia. Echocardiographic features included: concentric left vetricular wall thickening, increased left ventricular and diastolic and systolic dimensions, and an increase in endocardial echogenicity. Abdominal radiographic abnormalities included: hepatosplenomegaly, peritoneal effusion, renomegaly, adrenal gland mineralization, and paralumbar and diaphragmatic musculature enlargement. Abdomlnal ultrasonographic abnormalities included: irregularly thickened muscular portion of the diaphragm; hypoechogenicity of the liver; peritoneal effusion; hepatosplenomegaly; renomegaly with hyperechoic cortex and medulla; and adrenal gland mineralization. The irregular scalloped appearance of the diaphragm (particularly along the ventral/sternal margin) was a consistenl radiographic abnormlity in the two cats with hypertrophic feline muscular dystrophy after the age of 7 months. This finding was confirmed by ultrasound as a thickened irregular, hyperechoic diaphragm. A diagnosis of hypertrophic feline muscular dystrophy should be strongly suspected if this abnormality is identified

    Full Text Available Background/Aim. Posterior breast cancers are located in the prepectoral region of the breast. Owing to this distinctive anatomical localization, physical examination and mammographic or ultrasonographic evaluation can be difficult. The purpose of the study was to assess possibilities of diagnostic mammography and breast ultrasonography in detection and differentiation of posterior breast cancers. Methods. The study included 40 women with palpable, histopathological confirmed posterior breast cancer. Mammographic and ultrasonographic features were defined according to Breast Imaging Reporting and Data System (BI-RADS lexicon. Results. Based on standard two-view mammography 87.5%, of the cases were classified as BI-RADS 4 and 5 categories, while after additional mammographic views all the cases were defined as BIRADS 4 and 5 categories. Among 96 mammographic descriptors, the most frequent were: spiculated mass (24.0%, architectural distortion (16.7%, clustered microcalcifications (12.6% and focal asymmetric density (12.6%. The differentiation of the spiculated mass was significantly associated with the possibility to visualize the lesion at two-view mammography (p = 0.009, without the association with lesion diameter (p = 0.083 or histopathological type (p = 0.055. Mammographic signs of invasive lobular carcinoma were significantly different from other histopathological types (architectural distortion, p = 0.003; focal asymmetric density, p = 0.019; association of four or five subtle signs of malignancy, p = 0.006. All cancers were detectable by ultrasonography. Mass lesions were found in 82.0% of the cases. Among 153 ultrasonographic descriptors, the most frequent were: irregular mass (15.7%, lobulated mass (7.2%, abnormal color Doppler signals (20.3%, posterior acoustic attenuation (18.3%. Ultrasonographic BI-RADS 4 and 5 categories were defined in 72.5% of the cases, without a significant difference among various histopathological types (p = 0

    Ponseti management usually requires Achilles tenotomy during the final stage of serial casting. However, we lack a good understanding of the sequential tendon healing process after tenotomy in the Ponseti bracing protocol. The purpose of this study was to clarify the ultrasonographic process of tendon healing in the gap for up to two years after Ponseti-type Achilles tenotomy in patients with clubfeet. We conducted an ultrasonographic study to clarify the sequential changes in gap healing for up to two years after tenotomy. The subjects were 23 patients with 33 clubfeet. Achilles tenotomy was performed at mean 10.4 (8-16) weeks after birth. Dynamic and static ultrasonography was performed before tenotomy and at 1, 2, 3, 4, 6, 8, and 12 weeks as well as at 4, 6, 12, 18, and 24 months after tenotomy. Continuity and gliding were noted within four weeks. The united portion continued to thicken for up to three months after tenotomy. Starting from the fourth month, the healed portion began to lose its thickness, and this process continued into the sixth month. At one year, the thickness of the tendon did not differ much from that of the tendon on the opposing foot. In cases where patients had clubfoot on both feet and underwent simultaneous tenotomies, measurement of the tendons could not be accurately compared. At two years after tenotomy, slight irregularity of the internal structure persisted when compared with the unaffected foot. In addition, clinical and X-ray findings were evaluated simultaneously, and no recurrence was confirmed. To our knowledge, our results are the first to describe the process of gap healing in the tendon after tenotomy up to and beyond two years, as recommended in the Ponseti bracing protocol. Level of evidence IV.

    Single homicide committed by women is rare. Serial killing is very infrequent, and the perpetrators are usually white, intelligent males with sadistic tendencies. Serial killing by women has, however, also been described. To conduct a review of published literature on female serial killers and consider its usefulness in assessing a presenting case. A literature review was conducted, after searching EMBASE, MEDLINE and PsycINFO. The presenting clinical case is described in detail in the context of the literature findings. Results The literature search revealed few relevant publications. Attempts to categorize the phenomenon of female serial killing according to patterns of and motives for the homicides have been made by some authors. The most common motive identified was material gain or similar extrinsic gratification while the 'hedonistic' sadistic or sexual serial killer seems to be extremely rare in women. There is no consistent theory of serial killing by women, but psychopathic personality traits and abusive childhood experiences have consistently been observed. The authors' case did not fit the description of a 'typical' female serial killer. In such unusual circumstances as serial killing by a woman, detailed individual case formulation is required to make sense of the psychopathology in each case. Publication of cases in scientific journals should be encouraged to advance our understanding of this phenomenon. Copyright (c) 2006 John Wiley & Sons, Ltd.

    To determine which organs can be reliably visualized ultrasonographically in bearded dragons (Pogona vitticeps), describe their normal ultrasonographic appearance, and describe an ultrasonographic technique for use with this species. Cross-sectional study. 14 healthy bearded dragons (6 females and 8 males). Bearded dragons were manually restrained in dorsal and sternal recumbency, and coelomic organs were evaluated by use of linear 7- to 15-MHz and microconvex 5- to 8-MHz transducers. Visibility, size, echogenicity, and ultrasound transducer position were assessed for each organ. Coelomic ultrasonography with both microconvex and linear ultrasound transducers allowed for visualization of the heart, pleural surface of the lungs, liver, caudal vena cava, aorta, ventral abdominal vein, gallbladder, fat bodies, gastric fundus, cecum, colon, cloaca, kidneys, and testes or ovaries in all animals. The pylorus was visualized in 12 of 14 animals. The small intestinal loops were visualized in 12 of 14 animals with the linear transducer, but could not be reliably identified with the microconvex transducer. The hemipenes were visualized in 7 of 8 males. The adrenal glands and spleen were not identified in any animal. Anechoic free coelomic fluid was present in 11 of 14 animals. Heart width, heart length, ventricular wall thickness, gastric fundus wall thickness, and height of the caudal poles of the kidneys were positively associated with body weight. Testis width was negatively associated with body weight in males. Results indicated coelomic ultrasonography is a potentially valuable imaging modality for assessment of most organs in bearded dragons and can be performed in unsedated animals.

    To review the sonographic findings of various diseases showing architectural distortion depicted under mammography. We collected and reviewed architectural distortions observed under mammography at our health institution between 1 March 2004, and 28 February 2007. We collected 23 cases of sonographically-detected mammographic architectural distortions that confirmed lesions after surgical resection. The sonographic findings of mammographic architectural distortion were analyzed by use of the BI-RADS lexicon for shape, margin, lesion boundary, echo pattern, posterior acoustic feature and orientation. There were variable diseases that showed architectural distortion depicted under mammography. Fibrocystic disease was the most common presentation (n = 6), followed by adenosis (n = 2), stromal fibrosis (n = 2), radial scar (n = 3), usual ductal hyperplasia (n = 1), atypical ductal hyperplasia (n = 1) and mild fibrosis with microcalcification (n = 1). Malignant lesions such as ductal carcinoma in situ (DCIS) (n = 2), lobular carcinoma in situ (LCIS) (n = 2), invasive ductal carcinoma (n = 2) and invasive lobular carcinoma (n = 1) were observed. As observed by sonography, shape was divided as irregular (n = 22) and round (n = 1). Margin was divided as circumscribed (n = 1), indistinct (n = 7), angular (n = 1), microlobulated (n = 1) and sipculated (n = 13). Lesion boundary was divided as abrupt interface (n = 11) and echogenic halo (n = 12). Echo pattern was divided as hypoechoic (n = 20), anechoic (n = 1), hyperechoic (n = 1) and isoechoic (n = 1). Posterior acoustic feature was divided as posterior acoustic feature (n = 7), posterior acoustic shadow (n = 15) and complex posterior acoustic feature (n = 1). Orientation was divided as parallel (n = 12) and not parallel (n = 11). There were no differential sonographic findings between benign and malignant lesions. This study presented various sonographic findings of mammographic architectural distortion and that it is

    Full Text Available Scapular fracture is rare in horse, but if happen can cause severe lameness. Due to overlapping of the contralateral scapula and thorax on the scapula, usually radiography is not helpful in its evaluation except in small amount of distal part. This study was intended to document the normal ultrasono-graphic appearance of the equine scapula. Right forelimbs of six horses were used. To facilitate image understanding, a zoning system was developed. Ultrasonography was performed using a 5–11 MHz linear array transducer. Ultrasonographic anatomy of scapula in different parts and planes was imaged and documented. This diagnostic imaging technique revealed a high potential in evaluating scapular surface and possible regional injuries. Ultrasonography could be considered an important addition to radiography in diagnosing fractures in the scapular region.

    Full Text Available In the popular literature context, this study aims to investigate: (1 how the formulation of the characterization of Dexter in the television serial Dexter violates the tradition of literary characterization, and (2 how the formula of moral values is dramatized through Dexter, who is a sociopath, psychopath, serial killer, and person without moral. The research object was the television serial Dexter, which ranks five in popularity in the world. The data were collected by documenting 84 episodes of the serial having been broadcast since 2006. They were analyzed by means of content analysis and qualitative descriptive techniques. Based on the findings, the conclusions are as follows. First, there is a violation or anachronism of characterization through the main character in the serial. Second, the dramatized moral values still contain conventional values although they are in different forms.

    Abdominal ultrasonography was performed in six adult captive caracals (Caracal caracal) to describe the normal abdominal ultrasonographic anatomy. Consistently, the splenic parenchyma was hyperechoic to the liver and kidneys. The relative echogenicity of the right kidney's cortex was inconsistent to the liver. The gall bladder was prominent in five animals and surrounded by a clearly visualized thin, smooth, regular echogenic wall. The wall thickness of the duodenum measured significantly greater compared with that of the jejunum and colon. The duodenum had a significantly thicker mucosal layer compared with that of the stomach. Such knowledge of the normal abdominal ultrasonographic anatomy of individual species is important for accurate diagnosis and interpretation of routine health examinations.

    2002-08-01

    Scholars have endeavored to study the motivation and causality behind serial murder by researching biological, psychological, and sociological variables. Some of these studies have provided support for the relationship between these variables and serial murder. However, the study of serial murder continues to be an exploratory rather than explanatory research topic. This article examines the possible link between serial killers and military service. Citing previous research using social learning theory for the study of murder, this article explores how potential serial killers learn to reinforce violence, aggression, and murder in military boot camps. As with other variables considered in serial killer research, military experience alone cannot account for all cases of serial murder. Future research should continue to examine this possible link.

    To evaluate whether the presence of hydronephrosis or cortical irregularity on ultrasonogram (US) in children with urinary tract infection (UTI) predicts the vesicoureteral reflux on voiding cystourethrography(VCUG) or or associated renal scar on DMSA scan, and to assess the clinical value of US. We analyzed 90 kidneys of 45 children with UTI, and US, VCUG and DMSA scan were performed in all cases. We evaluated the presence of hydroneprhosis and cortical irregularity on US, vesicoureteral reflux on VCUG and cortical defect on DMSA scan. We analyzed the sensitivity, specificity and positive and negative predictive values of US findings for detection of vesicoureteral reflux and cortical defect. Hydronephrosis on US showed 28% sensitivity for diagnosis of vesicoureteral reflux on VCUG, and was not significantly related with the grade of reflux.Cortical irregularity on US showed 31% sensitivity and 89% positive predictive value for cortical defect on DMSA scan. Hydronephrosis and cortical irregularity on US showed low sensitivities for diagnosis of refluxon VCUG and cortical defect on DMSA scan, however, ultrasonographic features of renal parenchyma were considered to be useful for prediction of renal scar

    The objective of this study was to investigate the clinical and ultrasonographic findings of women who had three-dimensional endovaginal ultrasound (EVUS) for the management of vaginal mesh complications. This was a retrospective study of patients that had EVUS due to mesh complications at a tertiary care center. The clinical charts were reviewed. The stored 3D volumes were reviewed regarding mesh information by two examiners independently. The predictive value of physical examination for detection of vaginal mesh was calculated. Patient outcomes were reviewed. Seventy-nine patients presented to our center because of their, or their physicians' concern regarding mesh complications. Forty-one (51.9%) had vaginal/pelvic pain, and 51/62 (82.2%) of sexually active women experienced dyspareunia. According to ultrasonographic findings, mesh or sling was not demonstrated in six patients who believed they have had mesh/sling implantation. The positive predictive value for vaginal examination was 94.5% (95% CI: 84.9%-98.8%), negative predictive value was 12.5% (95% CI: 2.8%-32.4%), sensitivity was 72.2% (95% CI: 59.4%-81.2%), and specificity was 50.0% (95% CI: 12.4%-87.6%). Fifty-four patients were indicated for surgical treatment. Median postoperative review was 12 (range, 3-18) months and 38/53 (71.7%) patients were satisfied. The most common complaints of vaginal mesh complications were pain and dyspareunia. EVUS appeared to be helpful for assessing mesh presence, location, and extent including planning for surgical intervention. © 2015 Wiley Periodicals, Inc.

The radiological findings were: Elevation of right dome of diaphragm (56%, restricted diaphragmatic movements (88%, right basal lung changes (48%, right pleural effusion (12%, and indistinct hazy diaphragmatic contour (40%. The ultrasonographic findings were: 87% of the abscesses were located in right lobe, 11% in left lobe and 2% in both lobes. Among the 25 patients, 76% showed solitary and 24% showed multiple abscesses. Of the 38 amoebic abscesses, 79% were hypoechoic, 13% were hyperechoic and 8% were anechoic. 11 patients were subjected for ultrasound-guided aspiration. CONCLUSION Ultrasound is a safe, reliable and non-invasive imaging modality for the diagnosis, followup and percutaneous interventions of amoebic liver abscesses. The sonographic resolution time of amoebic liver abscesses varies from 28 to 286 days.

    The objective of the investigations was to comparatively evaluate the size and shape of the liver on the basis of x-ray and ultrasonographic examinations and to estimate the liver parenchyma and intrahepatic vessels on the basis of ultrasonographic examinations. The studies were done on 64 dogs and 13 cats of different breed and sex, aged from 1 day to 18 years. The ultrasonographic examinations were done with the use of Bruel and Kjaer apparatus type 1849 and Concept 2000 by Dynamic Imaging. In 64 animals the ultrasonographic image of the liver was normal. In 7 cases an enlargement of the liver without any changes in the liver parenchyma was noted. An enlargement of intrahepatic veins was found in 8 cases (4 with circulatory insufficiency, 2 with ascites). The assessment of the size and shape of the liver done on that basis of ultrasound examinations agreed with that based on x-ray examinations. The ultrasonic examinations also allowed the evaluation of the liver parenchyma and intrahepatic veins. (author). 9 refs, figs, 3 tabs

    Many oil and gas producers and pipeline companies find themselves in an awkward position. They have invested millions of dollars in legacy serial communications systems and in most cases, millions more in older SCADA remote terminal units and electronic flow meters. There is a desire throughout most of the industry to convert these systems to Ethernet. This presentation will explore how Ethernet protocol offers advantages over the older serial communications in terms of peer to peer communication, faster polling cycles, and the ability to poll multiple devices at the same time.

    To study the complications related to leiomyomatosis in pregnancy by clinical and ultrasonographic assessment. A retrospective study. All pregnancies admitted to the 2nd Institute of Gynecology and Obstetrics, Policlinico Umberto I, in the period between January 1992 to December 1993 were surveyed. Gestational age at the time of ultrasonographic neoplasm diagnosis was 25.1 +/- 13.4 weeks, 'we found no correlation between maternal age or parity affecting pregnancy outcome, Leiomyomatosis complicated pregnancy rate was 1.68%. Myomatosis was diagnosed clinically in 25 of 67 cases (37.3%). Regarding the location of the neoplasm, 59% was located in the corpus-uteri, 21% was considered a diffuse neoplasm and the 14% was located in the fundus. Threatened abortion was the most frequent complication (20%), abortion was the second (16.4%). We observed an increased abortion threat rate (p pregnancies complicated by myomatosis, and the indication for surgery was given either primarily or exclusively by the presence of myomatous formation in 19 cases (50%). Our study suggests that location of the leiomyoma in relation to the placenta is a higher risk factor than its size, and that there is a higher risk for threats of abortion and abortion rates in pregnancies complicated by leiomyomatosis. We recommend that every pregnant woman with a suspected myoma should be ultrasonographically scanned.

    To demonstrate sonographic features of Hashimoto's thyroiditis according to the thyroid function. We reviewed 54 thyroid ultrasonographic examinations of untreated Hashimoto's thyroiditis. We reviewed thyroid ultrasonographic examinations and focused on the presence of ill-defined low echoic lesions and glandular enlargement. We performed another thyroid ultrasonographic examination of 14 healthy volunteers, in order to obtain normal size of thyroid gland. Comparison was made between these morphologic characteristics and functional stage of the disease. The mean diameter of thyroid gland was 2.16 ± 0.43 cm in patients with Hashimoto's thyroiditis, and 1.41 ± 0.42 cm in normal control group of the thyroid gland. There was no statistically significant relationship between thyroid function and size. There was morphologic abnormalities in 46 patients (85%). Among them, 7 patients revealed diffuse low echogenicity in the entire thyroid gland, 32 patients showed peripherally located, ill-defined focal hypoechoic lesion, and 7 patients showed solitary or multiple. well-defined nodular lesions. Decreased echogenicity of the thyroid gland was related to hypothyroid status. Hashimoto's thyroiditis has specific morphologue characteristics in ultrasonographic features, which are well correlated with thyroid function.

    Full Text Available This study was aimed to detect and record the clinical and ultrasonographic findings of the different complications resulted from the foreign bodies lodged in the compound stomach of cattle and buffaloes. A total of 105 animals (37 cattle and 68 buffaloes were subjected to study. Based on the clinical and ultrasonographic examination, animals were classified into; acute local reticuloperitonitis (ALRP (15 cattle and 28 buffaloes, chronic local reticuloperitonitis (CLRP (6 cattle and 14 buffaloes, acute diffuse reticuloperitonitis (ADRP (5 cattle and 3buffaloes, reticular abscesses (RA (4 cattle and 7 buffaloes, traumatic pericarditis (TP (6 cattle and16 buffaloes and liver abscess (one cattle. Results revealed that ALRP represented the highest percentage of 40.5% in cattle and 41.2 % in buffalos between the different complications of TRP. TP represented the second complications of higher incidence (16.2% in cows and 23.5% in buffalos. Liver abscess represented the lowest percentage (2.8% and was recorded in cows only. The pregnant animals were affected more than the non pregnant. Clinical findings represented in systemic reaction and pain tests were commonly encountered in TRP and its complications. Some of the affected animals were negatively respond to metal detector test. Results of the present study indicated that the ultrasonographic examination provide a specific echogenic pattern for the different complications of TRP. It was concluded that, clinical examination only is not efficient to give accurate diagnosis of foreign body lodged in the reticulum and rumen and their complications. Ultrasonography is a safe, non invasive diagnostic confirmatory method that could be used for early detection of such conditions.

    Rasmussen's syndrome is characterized by intractable seizures and progressive neuropsychiatric deterioration secondary to unilateral cortical inflammation and tissue destruction. Diagnosis of Rasmussen's syndrome in the early phase depends mainly on the clinical features. Neuroimaging and histopathologic examinations may not be specific during this period. We report a case of Rasmussen's syndrome followed by serial MRI and magnetic resonance spectroscopy (MRS) studies over a 3- to 16-month period. A healthy 6-year-old boy presented with focal motor seizures. An MRI study demonstrated prominent enlargement and T2 hyperintensity of the left mesial temporal lobe and perisylvian region. This early finding evolved to volume loss and later progressive atrophy of the ipsilateral hemisphere when epilepsia partialis continua occurred. Being aware of those early MRI features in a patient with increasing frequency of focal motor seizures should suggest Rasmussen's syndrome. In addition, we found prominently increased myoinositol concentration in atrophic cortex which might reflect increased gliosis in the late period of the disease. (orig.)

    Lymphangiectasia is one of the causes of protein-losing enteropathy in dogs and characteristic ultrasonographic small intestinal lesions have been previously described. The purpose of this study was to determine whether corn oil administered orally (COAO) would result in increased conspicuity of these characteristic small intestinal ultrasonographic lesions in dogs with lymphangiectasia. Affected dogs were included if they underwent corn oil administered orally and had a surgical full-thickness intestinal biopsy diagnosis of lymphangiectasia. Control dogs had normal clinical examination and standard laboratory test findings. Ultrasound images of duodenum, jejunum, and ileum were obtained prior to and 30, 60, 90, and 120 min after corn oil administered orally for all dogs. Parameters recorded for each ultrasound study were intestinal wall thickness, mucosal echogenicity, and presence or absence of hyperechoic mucosal striations (HMS) and a parallel hyperechoic mucosal line (PHML). Nine affected and five controls dogs were included in the study. Seven of the nine dogs with lymphangiectasia had hyperechoic mucosal striations prior to corn oil administered orally. Jejunal hyperechoic mucosal striations were significantly associated with lymphangiectasia at multiple time points (P dogs with lymphangiectasia 60 or 90 min after corn oil administered orally. Increased mucosal echogenicity was observed in all dogs at multiple time points after corn oil administered orally. A parallel hyperechoic mucosal line was present in the jejunum in 4/5 healthy and 6/9 dogs with lymphangiectasia at one or more time points after corn oil administered orally. Findings indicated that corn oil administered orally improves conspicuity of characteristic ultrasonographic lesions in dogs with lymphangiectasia, however some of these lesions may also be present in healthy dogs that recently received a fatty meal. © 2013 Veterinary Radiology & Ultrasound.

    To estimate whether, by using a new ultrasonographic technique (extended view; XTD view), young lean women with polycystic ovary syndrome (PCOS) have a more android fat distribution in comparison with normally menstruating women with ultrasonographic evidence of polycystic ovaries (PCO) and healthy control subjects, matched for both age and body mass index. Prospective observational study. University Hospital. Forty-nine lean women with PCOS, 42 eumenorrheic women with bilateral PCO and 40 healthy volunteers with regular ovulatory cycles. Fasting blood sampling, ultrasonographic and Doppler analyses and blood pressure monitoring. Medical examination, biochemical and hormonal parameters, ultrasonographic abdominal fat measurements, ultrasonographic evaluation of carotid intima-media thickness and Doppler analysis of ophthalmic artery. An oral glucose tolerance test was performed to analyze glucose, insulin and C-peptide levels. The XTD ultrasonographic preperitoneal area was significantly larger in women with PCOS than in control subjects (p=0.011). The preperitoneal/subcutaneous ratio was significantly higher in women with PCOS (1.1±0.26) compared with women with PCO (0.84±0.13; p=0.05) and control women (0.67±0.13; pPCOS women (1.93±0.57) than in control subjects (1.84±0.38; p=0.041). Total cholesterol, triglycerides and LDL cholesterol were significantly higher in women with PCOS than in those with PCO and in control subjects. Women with PCOS have an android fat pattern correlated with an age-dependent increased risk of cardiovascular diseases. © 2011 The Authors Acta Obstetricia et Gynecologica Scandinavica© 2011 Nordic Federation of Societies of Obstetrics and Gynecology.

    The uterus and ovaries of 50 patients with polycystic ovarian disease (PCOD) and 30 eumenorrheic women were studied with a real-time ultrasound mechanical sector scanner. Uterine and ovarian volumes (UV and OV) and the OV/UV ratio were calculated, and ovarian morphology was classified as prevalently solid and cystic. Both ovaries were displayed in 44 of the PCOD and in 25 of the normal patients and appeared bilaterally solid, cystic, or with different morphology, respectively, in 43.2%, 47.7%, and 9.1% of cases in the former group and in 76%, 20%, and 4% in the latter group. Statistically significant differences between normal and PCOD patients were found in OV, UV, and OV/UV ratio. Bilaterally enlarged ovaries with multiple tiny cysts, the classic ultrasonographic picture of the polycystic ovary, were found in only 16 (36.3%) of the PCOD cases, while 34 (77.3%) had an OV/UV ratio greater than 1 standard deviation above the mean. Four ultrasonographic ovarian patterns were observed in the PCOD patients: enlarged cystic; enlarged solid; normal-sized cystic; and normal-sized solid. These findings emphasize the need for a reconsideration of the ultrasonographic criteria of PCOD.

    2013-06-01

    Full Text Available The purpose of this investigation was to demonstrate the feasibility of a biopsy technique by performing serial evaluations of tissue samples of the forelimb superficial digital flexor tendon (SDFT in healthy horses and in horses subjected to superficial digital flexor tendonitis induction. Eight adult horses were evaluated in two different phases (P, control (P1 and tendonitis-induced (P2. At P1, the horses were subjected to five SDFT biopsies of the left forelimb, with 24 hours (h of interval. Clinical and ultrasonographic (US examinations were performed immediately before the tendonitis induction, 24 and 48 h after the procedure. The biopsied tendon tissues were analyzed through histology. P2 evaluations were carried out three months later, when the same horses were subjected to tendonitis induction by injection of bacterial collagenase into the right forelimb SDFT. P2 clinical and US evaluations, and SDFT biopsies were performed before, and after injury induction at the following time intervals: after 24, 48, 72 and 96 h, and after 15, 30, 60, 90, 120 and 150 days. The biopsy technique has proven to be easy and quick to perform and yielded good tendon samples for histological evaluation. At P1 the horses did not show signs of localised inflammation, pain or lameness, neither SDFT US alterations after biopsies, showing that the biopsy procedure per se did not risk tendon integrity. Therefore, this procedure is feasible for routine tendon histological evaluations. The P2 findings demonstrate a relation between the US and histology evaluations concerning induced tendonitis evolution. However, the clinical signs of tendonitis poorly reflected the microscopic tissue condition, indicating that clinical presentation is not a reliable parameter for monitoring injury development. The presented method of biopsying SDFT tissue in horses enables the serial collection of material for histological analysis causing no clinical signs and tendon damage seen

    Full Text Available Omasal impaction is a serious disease problem in cattle in India, but it is difficult to diagnose clinically. Ultrasonography has been proposed for the noninvasive evaluation of omasal disease. The objectives of this study were to compare the in vitro and in vivo ultrasonographic appearance of the omasum and to compare omasal appearance, limits, and size in clinically healthy cows with those in cows having confirmed omasal impaction. A 3.5 MHz curvilinear transducer was used to image and record the appearance of the omasum in vitro in a water bath, and its appearance, dorsal and ventral limits, and size in 10 healthy Indian Jersey/Red Sindhi crossbred cows. The results were compared with the ultrasonographic data collected from 5 cows with omasal impaction, as confirmed at necropsy. On moving the transducer dorsoventrally in each intercostal space and below the costal arch, the wall of omasum could be seen as an echogenic arc-like structure. The difference between mean dorsoventral extents of the normal and impacted omasums was statistically insignificant. These results suggest that ultrasonographic imaging may not be useful in the diagnosis of omasal impaction in Indian crossbred cows, however, additional studies may be warranted.

  14. The neural signature of emotional memories in serial crimes.

    2017-10-01

    Neural plasticity is the process whereby semantic information and emotional responses are stored in neural networks. It is hypothesized that the neural networks built over time to encode the sexual fantasies that motivate serial killers to act should display a unique, detectable activation pattern. The pathological neural watermark hypothesis posits that such networks comprise activation of brain sites that reflect four cognitive components: autobiographical memory, sexual arousal, aggression, and control over aggression. The neural sites performing these cognitive functions have been successfully identified by previous research. The key findings are reviewed to hypothesise the typical pattern of activity that serial killers should display. Through the integration of biological findings into one framework, the neural approach proposed in this paper is in stark contrast with the many theories accounting for serial killers that offer non-medical taxonomies. The pathological neural watermark hypothesis offers a new framework to understand and detect deviant individuals. The technical and legal issues are briefly discussed. Copyright © 2017 Elsevier Ltd.

    Objective To identify the optimal sites for classification of early gout by ultrasonography. Methods Sixty patients with monosodium urate crystal-proven gout (25 with early gout [≤2-year symptom duration], 35 with late gout [>2-year symptom duration], and 36 normouricemic healthy controls) from one centre were prospectively evaluated. Standardized blinded ultrasound examination of 36 joints and the triceps and patellar tendons was performed to identify tophi and the double contour (DC) sign. Results Ultrasonographic sensitivity was lower in early than late gout. Binary logistic regression analysis showed that two ultrasonographic signs (tophi in the first metatarsophalangeal joint [odds ratio, 16.46] and the DC sign in the ankle [odds ratio, 25.18]) significantly contributed to the final model for early gout diagnosis (sensitivity and specificity of 84% and 81%, respectively). The inter-reader reliability kappa value for the DC sign and tophi was 0.712. Conclusions Four-joint investigation (both first metatarsophalangeal joints for tophi and both ankles for the DC sign) is feasible and reliable and could be proposed as a screening test for early ultrasonographic gout classification in daily practice.

    To evaluate the sonographic findings of fetal congenital intracranial teratoma. From 1994 to 2002, of the 11 fetuses which had been diagnosed with fetal intracranial tumors after second level fetal ultrasonography, the six that were confirmed after autopsy as congenital intracranial teratomas were included in our study. The sonographic findings, including size, homogeneity, echogenicity compared with surrounding normal brain tissues, cystic components, and tumor related calcification, were retrospectively evaluated. The incidence of fetal congenital intracranial teratoma out of all fetal intracranial tumors was 54.5% (6 of 11 cases) during the 8-year period. The mean mass size was 7.4 cm (3.0-15.0 cm). Two thirds of (4/6) of the teratoma cases showed high echogenicity compared with normal brain tissues, and two thirds (4/6) showed heterogeneous echogenicity. Four teratoma cases (67%) showed cysts in the mass with a mean size of 1.9cm. One third (2/6) showed calcifications within the tumor. Out of the six cases, two had oropharyngeal teratoma with extension into the intracranial portion (so called epignathus) and showed homogenous mass without any cysts or calcifications. The typical sonographic appearance of intracranial teratoma was a heterogeneous, hyperechoic mass with cysts. In the epignathus cases, the sonographic appearances differed somewhat from the others. An understanding of the sonographic findings of fetal intracranial teratoma will help in the timely counseling of the parents and in obstetric decision making

    To demonstrate sonographic features of Hashimoto's thyroiditis according to the thyroid function. We reviewed 54 thyroid ultrasonographic examinations of untreated Hashimoto's thyroiditis. We reviewed thyroid ultrasonographic examinations and focused on the presence of ill-defined low echoic lesions and glandular enlargement. We performed another thyroid ultrasonographic examination of 14 healthy volunteers, in order to obtain normal size of thyroid gland. Comparison was made between these morphologic characteristics and functional stage of the disease. The mean diameter of thyroid gland was 2.16 {+-} 0.43 cm in patients with Hashimoto's thyroiditis, and 1.41 {+-} 0.42 cm in normal control group of the thyroid gland. There was no statistically significant relationship between thyroid function and size. There was morphologic abnormalities in 46 patients (85%). Among them, 7 patients revealed diffuse low echogenicity in the entire thyroid gland, 32 patients showed peripherally located, ill-defined focal hypoechoic lesion, and 7 patients showed solitary or multiple. well-defined nodular lesions. Decreased echogenicity of the thyroid gland was related to hypothyroid status. Hashimoto's thyroiditis has specific morphologue characteristics in ultrasonographic features, which are well correlated with thyroid function.

Serials Review, 39(4, 216-226. http://dx.doi.org/10.1016/j.serrev.2013.10.004 Abstract Objective – To examine industry standards for the management of electronic serials and measure the adoption of electronic serials over print. Design – Survey questionnaire. Setting – Email lists aimed at academic librarians working in serials management. Subjects – 195 self-selected subscribers to serials email lists. Methods – The author created a 20 question survey that consisted primarily of closed-ended questions pertaining to the collection demographics, staff, budget, and tools of serials management groups in academic libraries. The survey was conducted via Survey Monkey and examined using the analytical features of the tool. Participants remained anonymous and the survey questions did not ask them to reveal identifiable information about their libraries. Main Results – Collection demographics questions revealed that 78% of surveyed librarians estimated that print-only collections represented 40% or fewer of their serials holdings. The author observed diversity in the factors that influence print to digital transitions in academic libraries. However 71.5% of participants indicated that publisher technology support like IP authentication was required before adopting digital subscriptions. A lack of standardization also marked serials workflows, department responsibilities, and department titles. The author did not find a correlation between serials budget and the enrollment size of the institution. Participants reported that they used tools from popular serials management vendors like Serials Solutions, Innovative Interfaces, EBSCO, and Ex Libris, but most indicated that they used more than one tool for serials management. Participants specified 52 unique serials management products used in their libraries. Conclusion

    Splenic rupture is a rare but potentially fatal complication of infectious mononucleosis. Athletes returning to contact sports following infectious mononucleosis are at potential risk of splenic rupture secondary to abdominal trauma. No clear consensus exists as to when it is safe to allow these athletes to return to contact sports. Suggested periods of abstinence have ranged from 2 weeks to 6 months. We outline our experiences with the use of abdominal ultrasonography at 1 month after the diagnosis of infectious mononucleosis as a means of determining when athletes can safely return to contact sports. Our study group was made up of 19 such patients (mean age: 16.7 yr). We found that 16 of these patients (84%) had normal splenic dimensions on ultrasonography 1 month after diagnosis, and they were therefore allowed to return to contact sports. While the remaining 3 patients had an enlarged spleen at 1 month, their splenic dimensions had all returned to normal when ultrasonographic examination was repeated at 2 months postdiagnosis. We conclude that serial abdominal ultrasonography allows for informed decision making in determining when athletes can safely return to contact sports following infectious mononucleosis.

    Full Text Available Opportunity recognition is a fundamental research issue in entrepreneurship which this paper empirically investigates for serial entrepreneurs. Initially key definitions and boundary conditions of opportunity recognition are explored to elucidate the relevant motivators driving serial entrepreneurs. After operationalising the various concepts, data is collected by surveying serial entrepreneurs (n= 77 based on pre-determined selection criteria. Since the study’s objective is to build solid theory on these new phenomena, descriptive analysis on the empirical results is provided. To test the hypotheses inferential statistics employing parametric and non-parametric tests are used. The findings reveal that the opportunity recognition behaviours are manifest among serial entrepreneurs, with few significant differences on how many new, major businesses have been pursued, or whether they can be said to be successes.

  6. External validation of fatty liver index for identifying ultrasonographic fatty liver in a large-scale cross-sectional study in Taiwan.

    Full Text Available The fatty liver index (FLI is an algorithm involving the waist circumference, body mass index, and serum levels of triglyceride and gamma-glutamyl transferase to identify fatty liver. Although some studies have attempted to validate the FLI, few studies have been conducted for external validation among Asians. We attempted to validate FLI to predict ultrasonographic fatty liver in Taiwanese subjects.We enrolled consecutive subjects who received health check-up services at the Taipei Veterans General Hospital from 2002 to 2009. Ultrasonography was applied to diagnose fatty liver. The ability of the FLI to detect ultrasonographic fatty liver was assessed by analyzing the area under the receiver operating characteristic (AUROC curve.Among the 29,797 subjects enrolled in this study, fatty liver was diagnosed in 44.5% of the population. Subjects with ultrasonographic fatty liver had a significantly higher FLI than those without fatty liver by multivariate analysis (odds ratio 1.045; 95% confidence interval, CI 1.044-1.047, p< 0.001. Moreover, FLI had the best discriminative ability to identify patients with ultrasonographic fatty liver (AUROC: 0.827, 95% confidence interval, 0.822-0.831. An FLI < 25 (negative likelihood ratio (LR- 0.32 for males and <10 (LR- 0.26 for females rule out ultrasonographic fatty liver. Moreover, an FLI ≥ 35 (positive likelihood ratio (LR+ 3.12 for males and ≥ 20 (LR+ 4.43 for females rule in ultrasonographic fatty liver.FLI could accurately identify ultrasonographic fatty liver in a large-scale population in Taiwan but with lower cut-off value than the Western population. Meanwhile the cut-off value was lower in females than in males.

  7. Testing Cross-Sectional Correlation in Large Panel Data Models with Serial Correlation

    Full Text Available This paper considers the problem of testing cross-sectional correlation in large panel data models with serially-correlated errors. It finds that existing tests for cross-sectional correlation encounter size distortions with serial correlation in the errors. To control the size, this paper proposes a modification of Pesaran’s Cross-sectional Dependence (CD test to account for serial correlation of an unknown form in the error term. We derive the limiting distribution of this test as N , T → ∞ . The test is distribution free and allows for unknown forms of serial correlation in the errors. Monte Carlo simulations show that the test has good size and power for large panels when serial correlation in the errors is present.

    Full Text Available Background: Subacute granulomatous thyroiditis (SGT is an inflammatory disease that presents with different clinical and cytological characteristics. Although the diagnosis is generally made clinically, imaging methods and fine-needle aspiration (FNA may provide assistance, particularly in atypical cases. The objective of this study is to reveal the ultrasonographic (USG and cytological characteristics of SGT. Materials and Methods: The clinical, USG and cytological findings of 21 cases diagnosed with SGT were reviewed. Results: Ultrasonographic data was available in 20 cases. A hypoechoic thyroid nodule with irregular margins was detected in 12 of the 20 total cases. Of these, 9 cases complained about pain in the thyroid lodge and generally had unilateral lesions, heterogeneous and hypoechoic areas with indistinct margins, rather than nodular lesions, which were seen in 7 cases. Cytologically, the multinuclear giant cells (MNGCs found in all cases were accompanied by a dirty background containing varying numbers of granulomatous structures, including isolated epithelioid histiocytes, proliferated/regenerated follicle epithelium cells and inflammatory cells and colloid. Conclusion: Though hypoechoic and heterogeneous areas with irregular margins are strongly associated with thyroiditis, SGT may also appear as painful or painless hypoechoic, solid nodules and generate challenges in differential diagnosis. Although the most remarkable characteristic observed in FNA cytology was the presence of multiple MNGCs with cytoplasm, a dirty background accompanied by mild-moderate cellularity, degenerated-proliferated follicular epithelium cells, rare epithelioid granulomas and mixed type inflammatory cells are characteristic for SGT. The assessment of these radiological and cytological findings in conjunction with clinical findings will assist in the achievement of an accurate diagnosis.

    Purpose: To evaluate the ultrasonographic and CT findings of tuberculous peritonitis. Material and Methods: Ultrasonographic and CT findings of 11 patients with the ascitic type of tuberculous peritonitis were reviewed. Results: All patients had ascites, and ultrasonography (US) demonstrated fine complete and incomplete mobile septations in 10 patients. In 5 of them, the ascites had a lattice-like appearance. Diffuse regular peritoneal thickening was detected in all patients by CT and in 10 patients by US. CT demonstrated infiltration of the greater omentum in 9 patients, whereas US showed omental thickening in only 5 patients. Conclusion: Peritoneal and omental thickening detected by CT and ascites with fine, mobile septations shown by US strongly suggest the ascitic type of tuberculous peritonitis. The 2 imaging modalities should be used together for accurate diagnosis of tuberculous peritonitis. (orig.).

    2006-01-01

    Introduction: Ultrasonographic techniques are commonly used for the imaging of various tissue structures and organs, including the eyeball and orbit. The non-invasive ultrasound imaging is safe for the patient and may be repeated after a short time unlike in the case of other radiological techniques. In pediatric ophthalmology, ultrasonography plays a major role as an auxiliary examination for the diagnosis of various intraocular diseases, pathologies of the retina and choroid, and retrobulbar conditions. Ultrasonography is of major importance in diagnosing eye disorders associated with opacity preventing visual inspection of the posterior eye segment. Methods: Among ultrasonographic techniques in pediatric ophthalmology the most frequently used are B-scan, A-scan, and Doppler ultrasonography. Because of the resolution of ultrasonographic methods in comparison to radiological techniques, they play an important role in monitoring the dynamics of pathological processes in retinopathy of prematurity (ROP). Other radiological methods such as CT, MRI or subtractive angiography do not offer a detailed view of retinal attachment or vitreo-retinal proliferation. Conclusion: Ultrasonography as an auxiliary examination at subsequent stages of ROP helps to document the changes and in case of corneal opacity connected with progression of vitreo-retinal abnormalities is the basis for the diagnosis.

    Studies documenting the application of ultrasonography to depict normal and pathological changes in koalas (Phascolarctos cinereus), especially in the male, are scarce. Sixty-two wild koalas were used in this study to define ultrasonographic protocols and features for the assessment of the male koala reproductive tract. Testis, epididymis and spermatic cord were examined using a hockey stick transducer. The normal koala testis showed a homogeneous echogenicity and an obvious hyper-echoic band corresponding to the tunica albuginea. The cauda epididymis was characterised by hypo- and hyper-echoic regions and was most effectively imaged in sagittal section. The koala prostate was assessed using a micro-curved transducer positioned midline, caudal to the bladder. On transverse section, it showed distinct margins and a well-defined internal structure, although the prostatic urethra was not apparent on most scans. To image the bulbourethral glands (BGs), the hockey stick transducer was placed lateral to the cloaca. BGIII was located just below the skin, while BGII was located deeper than BGIII. BGI was too small and not sufficiently echogenic to be detected. The ultrasonographic appearance of the BGs was similar to that of the testes but with more obvious hypo-echoic stippling. This comprehensive review of the ultrasonographic appearance of normal male koala reproductive tract can be used by veterinarians and others, in zoos or those working with wild koalas, during assessment of the reproductive tract of male koalas in relation to seasonal changes in accessory gland function or for the pathological investigation of reproductive lesions and infertility problems.

    The aim of the investigation was the comparison of the diagnostic value of the clinical, radiological and ultrasonographic examinations in the diagnosis of focal changes in the liver and the determination of the relations between the changes in the ultrasound image of the liver and the changes in other organs. The investigation was performed on 24 animals: 20 dogs and 4 cats of different breeds and sex, aged 1.5 to 14 years. The ultrasonographic examinations were done using the apparatus of Bruel and Kjaer type 1849 and Concept 2000 of Dynamic Imaging. The following changes were diagnosed in the ultrasonic picture: echogenic changes in 5 animals, hypoechogenic in 2 animals, normechogenic in 2 animals, hyperechogenic in 8 animals and changes of mixed echogenicity in 5 animals. The connection between clinical signs and the results of X-ray and ultrasonographic examination allowed the recognition of the changes in the liver as cysts, abscess and neoplasm of the liver.

    1995-08-01

    Raising the drinking age twice in New York State in the 1980s might have created a generation of "serial beginning drinkers." Findings indicate that when young adults become beginning drinkers, their chances of drinking-driving increase; when they become serial beginning drinkers, their involvement in drinking-driving remains high over time. The beginning drinkers belong to a special historical period and are only composed of birth cohorts of 3 or 4 years (mainly early 1960s). The effect of the serial beginning drinker should fade out as those birth cohorts grow into maturity.

    Vascular enhancement (VE) technology(ClarifyTM) is a new technique in vascular, B-mode imaging. The purpose of this study was to evaluate the value of VE technology in ultrasonographic diagnosis of abdominal vasculature. Seventy-one adult patients (39 men and 32 women: age range, 25-89 years: mean age, 56 years) who had undergone abdominal ultrasonography were included in this study. The imaging was performed with a 1.8-4.0 MHz convex array transducer (SONOLINE, Antares, Siemens Medical Solutions, WA) by an abdominal radiologist. The radiologist obtained images of the same vascular area with each of conventional ultrasonography imaging (CUS), tissue harmonic imaging (THI), CUS plus VE technique and THI plus VE technique. Images were divided into normal (56) and abnormal (15) groups. The vessel visibility, conspicuity of the vascular wall and contrast resolution with adjacent structures were evaluated in the normal group, and the lesion conspicuity and border sharpness were evaluated in the abnormal group. On the PACS monitor, the images were graded into four grades by two radiologists in consensus. Statistical analysis was performed using Wilcoxon signed rank test. In the normal group, all parameters of the ultrasonographic imaging which applied the VE technique were superior to those of the imaging without VE technique (p < 0.05). In the abnormal group, combined use of VE technique with CUS or THI provided better results than CUS or THI alone in terms of lesion conspicuity and border sharpness (p < 0.05). THI combined with VE technique provided the best image quality among the 4 ultrasonographic methods examined in this study for the evaluation of both normal and abnormal abdominal vessels (p < 0.05). VE technology was a helpful technique to evaluate the abdominal vasculature. Furthermore, VE technique combined with THI provided better image quality than other ultrasonographic methods in the evaluation of abdominal vessels

    Full Text Available Abstract Background We recently reported poor inter-observer agreement in identifying and quantifying individual ultrasonographic features of polycystic ovaries. Our objective was to determine the effect of a training workshop on reducing inter-observer variation in the ultrasonographic evaluation of polycystic ovaries. Methods Transvaginal ultrasound recordings from thirty women with polycystic ovary syndrome (PCOS were evaluated by three radiologists and three reproductive endocrinologists both before and after an ultrasound workshop. The following endpoints were assessed: 1 follicle number per ovary (FNPO, 2 follicle number per single cross-section (FNPS, 3 largest follicle diameter, 4 ovarian volume, 5 follicle distribution pattern and 6 presence of a corpus luteum (CL. Lin's concordance correlation coefficients (rho and kappa statistics for multiple raters (kappa were used to assess level of inter-observer agreement (>0.80 good, 0.60 – 0.80 moderate/fair, Results Following the workshop, inter-observer agreement improved for the evaluation of FNPS (rho = 0.70, delta rho = +0.11, largest follicle diameter (rho = 0.77, delta rho = +0.10, ovarian volume (rho = 0.84, delta rho = +0.12, follicle distribution pattern (kappa = 0.80, delta kappa = +0.21 and presence of a CL (kappa = 0.87, delta kappa = +0.05. No improvement was evident for FNPO (rho = 0.54, delta rho = -0.01. Both radiologists and reproductive endocrinologists demonstrated improvement in scores (p Conclusion Reliability in evaluating ultrasonographic features of polycystic ovaries can be significantly improved following participation in a training workshop. If ultrasonographic evidence of polycystic ovaries is to be used as an objective measure in the diagnosis of PCOS, then standardized training modules should be implemented to unify the approach to evaluating polycystic ovarian morphology.

    To evaluate the usefulness of the transrectal ultrasound in infertile men with suspected obstructive lesions of sperm transport system. We performed transrectal US in 26 infertile patients in whom obstructive lesions of sperm transport system were suspected in physical examination and laboratory data. 7.0 MHz transrectal transducer was used and the content of analysis of sonographic findings was the presence of vas deferens, seminal vesicle and ejaculatory duct. Also, we measured the width of seminal vesicle and diameter of ejaculatory duct. Transrectal US revealed an accurate diagnosis in 12 infertile men who had obstructive lesions and associated abnormalities in distal sperm transport system, two of congenital bilateral absence of the vasa deferentia and seminal vesicles, two of congenital unilateral absence of the vas deferens and seminal vesicle, three of dilatation of seminal vesicles, and five of dilatation of ejaculatory ducts and proximal ducts. The other 14 patients who had normal findings on transrectal US were revealed to have testicular failure (10 patients) and obstruction of proximal sperm transport system (4 patients) which were beyond the field-of-view of transrectal US. Transrectal US is the useful diagnostic method for the evaluation of infertile men with suspected obstructive lesions of sperm transport system. It can possibly decrease the need for the invasive vasography and may be helpful in the guidance of appropriate management of male infertility

    Primary lymphoma of the trachea is extremely rare and clinical presentation is nonspecific. CT findings are focal tracheal narrowing caused by a solitary mass or polypoid thickening of the tracheobronchial wall caused by diffuse infiltration of the submucosa. However, US finding of primary lymphoma of the trachea has been not reported. We experienced a case of primary lymphoma of the trachea presenting as a homogenous hypoechoic mass, and discuss ultrasonographic and CT findings of the case

    Two experiments examined the dynamic interaction between cognitive resources in short-term memory and bimanual object manipulation by extending recent research by Logan and Fischman (2011). In Experiment 1, 16 participants completed a bimanual end-state comfort task and a memory task requiring serial recall of 12 words or pictures. The end-state comfort task involved moving two glasses between two shelves. Participants viewed the items, performed the end-state comfort task, and then serially recalled the items. Recall was evaluated by the presence or absence of primacy and recency effects. The end-state comfort effect (ESCE) was assessed by the percentage of initial hand positions that allowed the hands to end comfortably. The main findings indicated that the ESCE was disrupted; the primacy effect remained intact; and the recency effect disappeared regardless of the type of memory item recalled. In Experiment 2, 16 participants viewed six items, performed an end-state comfort task, viewed another six items, and then serially recalled all 12 items. Results were essentially the same as in Experiment 1. Findings suggest that executing a bimanual end-state comfort task, regardless of when it is completed during a memory task, diminishes the recency effect irrespective of the type of memory item.

    The objective of this study was to determine if very early ultrasonographic measurements obtained from human and baboon are comparable. For this purpose, the gestational, amniotic and yolk sacs, embryonic crown rump length (CRL) and heart rate were measured ultrasonographically between 35 and 47 days from the mean day of a three-day mating period in baboons (n=18) and between 42 to 58 days from fertilization as calculated from the CRL measurements in human pregnancies (n=82). Ultrasonographic measurements from both species were then plotted in the same graph using Carnegie stages of embryonic development as the independent variable to allow for visual comparisons. Mean gestational age at ultrasonographic studies was significantly different for humans and baboons (50.4 vs. 41 days, respectively; p>0.01). Significant correlations (p>0.01) were noted between ultrasonographic measurements and Carnegie stages of development in both humans and baboons. Only the gestational and the yolk sacs were significantly smaller in baboons than in humans (p>0.05). The findings that embryonic CRL, extra-embryonic space and heart rate are very similar between the 17th and 23rd Carnegie developmental stages make the baboon a promising surrogate of human pregnancy for investigations using celocentesis.

    Serial transcriptomics experiments investigate the dynamics of gene expression changes associated with a quantitative variable such as time or dosage. The statistical analysis of these data implies the study of global and gene-specific expression trends, the identification of significant serial changes, the comparison of expression profiles and the assessment of transcriptional changes in terms of cellular processes. We have created the SEA (Serial Expression Analysis) suite to provide a complete web-based resource for the analysis of serial transcriptomics data. SEA offers five different algorithms based on univariate, multivariate and functional profiling strategies framed within a user-friendly interface and a project-oriented architecture to facilitate the analysis of serial gene expression data sets from different perspectives. SEA is available at sea.bioinfo.cipf.es. PMID:20525784

    We wanted to demonstrate and compare the serial high-resolution CTs (HRCT) and the pulmonary function test (PFT) findings of the usual interstitial pneumonia (UIP) and the non-specific interstitial pneumonia (NSIP). The serial HRCT scans and the PFT results were retrospectively analysed and compared for 35 patients having UIP without significant honeycombing (UIP-w/o hc, < 5% of honeycombing at CT), 35 patients having UIP with honeycombing (UIP-w/i hc, {>=} 5% of honeycombing), and 25 patients with NSIP. The mortality rates were also compared. Follow-up CT scans were available in 75 patients (29 UIP-w/o hc patients, 22 UIP-w/i hc patients and 24 NSIP patients) and the follow-up periods ranged from 150 to 2,370 days. The initial and follow-up PFT data were available for 71 patients. On the initial CT, significant differences were present between the UIP-w/i hc patients and both the UIP-w/o hc patients and the NSIP patients in the overall extent, ground-glass opacity (GGO) away from the reticulation, reticulation and honeycombing (all {rho} < 0.05). Improvement was noticed in five (17%) of 29 UIP-w/o hc patients, none of 22 UIP-w/i hc patients, and 9 (37%) of 24 NSIP patients; deterioration was noted in six (21%) UIP-w/o hc patients, two (9%) UIP-w/i hc patients and three (13%) NSIP patients ({rho} 0.044 between UIP-w/o and UIP-w/i hc; {rho} = 0.637 between UIP-w/o hc and NSIP; {rho} = 0.007 between UIP-w/i hc and NSIP). The serial changes of the pulmonary function in the NSIP patients were different from those noted for the UIP-w/i hc and UIP-w/o hc patients ({rho} = 0.440 between UIP-w/o and UIP-w/i hc; {rho} = 0.022 between UIP-w/o hc and NSIP; {rho} =0.003 between UIP-w/i hc and NSIP). Five (14%) of the 35 patients with UIP-w/o hc, 16 (46%) of the 35 patients with UIP-w/i hc and three (12%) of the 25 patients with NSIP died ({rho} = 0.002, comparison for the three groups). On CT, NSIP and UIP-w/o hc patients have similar patterns of parenchymal abnormalities and

    Serial computed tomographic scans were performed on seven children with neurodegenerative disorders. In two cases of white-matter diseases (Krabbe's disease and metachromatic leukodystrophy), diffuse, low-density lesions of white matter were visible in the early stage of the diseases. In one case of adrenoleukodystrophy, regional low-density lesions of the white matter around the posterior horns and peculiar high-density strip lesions were visible in the early stage. In two cases of storage-type gray-matter diseases (Tay-Sachs' and infantile Gaucher's disease), there were no abnormalities in the early stage, but diffuse cortical atrophies in the late stage. In one case of Leigh's disease, there were small, low-density lesions of the basal ganglia and multiple low-density lesions of the gray matter in the early stage. In one case of subacute sclerosing panencephalitis, there were no abnormalities in the early stage, but small, low-density lesions of the basal ganglia and diffuse cerebral atrophies in the late stage. Diagnostic values were recognized dominantly in two cases of adrenoleukodystrophy and Leigh's disease. In the other cases, however, serial CT scans were useful in the diagnostic process. (author).

    Serial ultrasonographic examinations were performed daily on 9 Miniature Schnauzer bitches from the 15th day of gestation until parturition to determine the time the gestational structures were first detected. The gestational age was timed from the day of ovulation (day 0), which was estimated to occur when the plasma progesterone concentration was >4.0 ng/ml. The gestational length in 9 Miniature Schnauzer bitches was found to be 63.0 +/- 1.7 (range 61-65) days. The initial detection of the fetal and extra-fetal structures were as follows: gestational sac at day 18.0 +/- 0.9 (17-19); zonary placenta in the uterine wall at day 24.9 +/- 1.1 (23-26); yolk sac membrane at day 25.0 +/- 0.9 (24-26); amnionic membrane at day 27.7 +/- 1.0 (26- 29); embryo initial detection at day 22.6 +/- 0.5 (22-23); heartbeat at day 23.4 +/- 0.5 (23-24); fetal movement at day 32.5 +/- 0.8 (32-34); stomach at day 31.2 +/- 1.6 (29-33); urinary bladder at day 32.6 +/- 1.8 (31-35); skeleton at day 34.9 +/- 1.6 (34-38) and kidney at day 42.2 +/- 0.7 (41-43).

    Full Text Available Background and Aim: Cervical multifidus is considered as one of the most important neck stabilizers. Weakness and muscular atrophy of this muscle were seen in patients with chronic neck pain. Ultrasonographic imaging is a non-invasive and feasible technique that commonly used to record such changes and measure muscle dimensions. Therefore, the aim of this study was to evaluate the reliability of ultrasonographic measurement of cervical multifidus muscle’s dimensions during isometric contraction of neck muscles. Materials and Method: Ten subjects (5 patients with chronic neck pain and 5 healthy subjects were recruited in this study. Cervical multifidus muscle’s dimensions were measured at the level of forth cervical vertebrae. Ultrasonographic measurement of cervical multifidus muscle at rest, 50% and 100% of maximal voluntary contraction (MVC were performed by one examiner within 1 week interval. The dimensions of cervical multifidus muscle including cross-sectional area (CSA, anterior posterior dimension (APD, and lateral dimension (LD were measured. Intraclass correlation coefficients (ICC, standard error of measurement (SEM and minimal detectable change (MDC were computed for data analysis.Results: The between days reliability of maximum strength of neck muscles and multifidus muscle dimensions at rest, 50% and 100% of MVC of neck muscles were good to excellent (ICC=0.75-0.99.Conclusion: The results of this study showed that ultrasonographic measuring of cervical multifidus muscle’s dimensions during isometric contraction of neck muscles at the level of C4 in females with chronic neck pain and healthy subjects is a reliable and repeatable method.

    To evaluate prenatal ultrasonographic findings of limb-body wall complex and to correlate them with autopsy findings. From October 1995 to June 2000, a retrospectively review of prenatal ultrasonography (US) of 11 patients with pathologically proven limb-body wall complex was done. US findings were then compared with autopsy findings. Prenatal ultrasonography revealed thoraco-abdominoschists (n=7.64%), kyphoscoliosis (n=7.64%), cranial defect (n=5.45%), limb defect (n=4.36%), facial defect (n=1.10%), amniotic band (n=5.45%), and umbilical cord anomaly (n=3.27%). Meanwhile, autopsy findings showed thoraco-abdominoschisis (n=8.72%), limb defect (n=7.64%), facial defect (n=7.64%), kyphoscoliosis (n=5.45%), cranial defect (n=5.45%), amniotic band (n=5.45%) and umbilical cord anomaly (n=4.36%). The most common ultrasonography features of limb-body wall complex were thoraco-abdominoschisis and kyphoscoliosis while the thoraco-abdominoschisis and limb defects were the most frequent findings at autopsy.

    This case series documents and examines the association between autoerotic asphyxiation, sadomasochism, and serial sexual murderers. Autoerotic asphyxiation, along with other paraphilias found in this population, is reviewed. Five cases of serial sexual killers who engaged in autoerotic asphyxiation were identified worldwide: four from the United States and one from Russia. Case reports for each are provided. All (100%) were found to have sexual sadism in addition to autoerotic asphyxiation. Furthermore, two (40%) had bondage fetishism, and two (40%) had transvestic fetishism, consistent with these paraphilias co-occurring in those with autoerotic asphyxiation. Overall the group averaged 4.0 lifetime paraphilias. Some possible relationships were observed between the offenders' paraphilic orientation and their modus operandi, e.g., all of these serial killers strangled victims-suggesting an association between their sadistic and asphyxiative paraphilic interests. The overlap of seemingly polar opposite paraphilias in this sample--sexual sadism and autoerotic asphyxiation--is explored from a historical and clinical perspective. Multiple commonalities shared between these five offenders and serial sexual murderers in general are addressed. A primary limitation of this study is its small sample size and empirical basis; the results may not be generalizable beyond the sample. The findings from this study support the supposition that crime scene behaviors often reflect paraphilic disturbances in those who commit serial sexual homicides.

    To evaluate serial computed tomography (CT) findings of pulmonary mucormycosis correlated with peripheral blood absolute neutrophil count (ANC). Between February 1997 and June 2016, 20 immunocompromised patients (10 males, 10 females; mean age, 48.9 years) were histopathologically diagnosed as pulmonary mucormycosis. On initial (n=20) and follow-up (n=15) CT scans, the patterns of lung abnormalities and their changing features on follow-up scans were evaluated, and the pattern changes were correlated with ANC changes. All patients were immunocompromised. On initial CT scans, nodule (≤3cm)/mass (>3cm) or consolidation with surrounding ground-glass opacity halo (18/20, 90%) was the most common pattern. On follow-up CT, morphologic changes (13/15, 87%) could be seen and they included reversed halo (RH) sign, central necrosis, and air-crescent sign. Although all cases did not demonstrate the regular morphologic changes at the same timeline, various combinations of pattern change could be seen in all patients. Sequential morphologic changes were related with recovering of ANC in 13 of 15 patients. Pulmonary mucormycosis most frequently presents as consolidation or nodule/mass with halo sign at CT. Morphologic changes into RH sign, central necrotic cavity or air-crescent sign occur with treatment and recovery of ANC. (orig.)

    Study was conducted to compare the clinical, haematobiochemical, radiographic and ultrasonographic features of traumatic reticuloperitonitis in bovines. Clinical cases (4 cows and 17 buffaloes) presented with a history of anorexia, fever, decreased milk yield and loss of defecation/scant faeces, were used. Haematological picture revealed neutrophilic leucocytosis with left shift and blood biochemical status showed elevated levels of total protein, albumin, and fibrinogen. Decreased plasma concentration of sodium, potassium and chloride was observed in majority of the cases. Radiographic examination revealed presence of multiple metallic foreign densities in the reticulum of the bovines. Ultrasonographically, morphological changes of reticular wall and reticulophrenic adhesions in cases of localised peritonitis were visualized. The presence of anechoic fluid without echogenic margins, not restricted to reticulum and sometimes with floating fibrinous shreds was observed in cases of diffuse peritonitis. Ultrasonography in B mode and B+ mode found helpful for the diagnosis of traumatic reticuloperitonitis and differentiation of localised peritonitis from diffuse peritonitis

    To determine the ultrasonographic features of the coelomic organs of healthy snakes belonging to the Boidae and Pythonidae families. 16 ball pythons (Python regius; 7 males, 8 females, and 1 sexually immature), 10 Indian rock pythons (Python molurus molurus; 5 males, 4 females, and 1 sexually immature), 12 Python curtus (5 males and 7 females), and 8 boa constrictors (Boa constrictor imperator; 4 males and 4 females). All snakes underwent complete ultrasonographic evaluation of the coelomic cavity; chemical restraint was not necessary. A dorsolateral approach to probe placement was chosen to increase image quality and to avoid injury to the snakes and operators. Qualitative and quantitative observations were recorded. The liver, stomach, gallbladder, pancreas, small and large intestines, kidneys, cloaca, and scent glands were identified in all snakes. The hemipenes were identified in 10 of the 21 (48%) male snakes. The spleen was identified in 5 of the 46 (11%) snakes, and ureters were identified in 6 (13%). In 2 sexually immature snakes, the gonads were not visible. One (2%) snake was gravid, and 7 (15%) had small amounts of free fluid in the coelomic cavity. A significant positive correlation was identified between several measurements (diameter and thickness of scent glands, gastric and pyloric walls, and colonic wall) and body length (snout to vent) and body weight. The study findings can be used as an atlas of the ultrasonographic anatomy of the coelomic cavity in healthy boid snakes. Ultrasonography was reasonably fast to perform and was well tolerated in conscious snakes.

    Guillain-Barré syndrome (GBS) is categorized into two major subtypes: acute inflammatory demyelinating polyneuropathy (AIDP) and acute motor axonal neuropathy (AMAN). However, a proportion of patients are electrophysiologically unclassified because of electrophysiological findings that do not fulfil AIDP or AMAN criteria, and underlying pathophysiological mechanisms and lesion distributions of unclassified patients are not well defined. The aims of this study are to elucidate disease pathophysiology and lesion distribution in unclassified patients. We retrospectively studied 48 consecutive GBS patients. Patients were classified on the basis of initial electrophysiological findings according to Ho's criteria. Clinical and serial electrophysiological examinations of unclassified patients were conducted. Twelve (25 %) GBS patients were unclassified. All unclassified patients were able to walk independently at 21 days after onset. No unclassified patients, except one patient with diabetes mellitus, had sensory nerve involvement. Eight patients underwent a follow-up study within 15 days of the initial study. Distal motor latencies (DMLs) of the left median motor nerve were found to be significantly and uniformly decreased compared with initial studies (p = 0.008). DMLs (p < 0.0001) and distal compound action potential (CMAP) durations (p = 0.002) of all nerves were significantly decreased, and distal CMAP amplitudes (p = 0.026) significantly increased compared with initial studies. In unclassified GBS patients, DML values during initial electrophysiological studies would be prolonged compared with expected values in the same patient unaffected by GBS and later improve rapidly with increased distal CMAP amplitudes without the development of excessive temporal dispersions. Lesions are also present in distal nerve segments caused by reversible conduction failure.

    AbstractCentral nervous system involvement manifesting as meningitis or meningoencephalitis is a known complication of scrub typhus, but very few spinal cord lesions such as acute transverse myelitis (ATM) have been reported in association with this disease. Scrub typhus patients with a spinal lesion present with neurologic symptoms including dysuria, motor, and sensory weakness. Herein, we describe a rare case of ATM associated with scrub typhus. Clinical characteristics, cerebrospinal fluid cytology, Orientia tsutsugamushi serum antibody titer, and serial magnetic resonance imaging scans resulted in a diagnosis of ATM associated with scrub typhus.

    Background and Aims The fatty liver index (FLI) is an algorithm involving the waist circumference, body mass index, and serum levels of triglyceride and gamma-glutamyl transferase to identify fatty liver. Although some studies have attempted to validate the FLI, few studies have been conducted for external validation among Asians. We attempted to validate FLI to predict ultrasonographic fatty liver in Taiwanese subjects. Methods We enrolled consecutive subjects who received health check-up services at the Taipei Veterans General Hospital from 2002 to 2009. Ultrasonography was applied to diagnose fatty liver. The ability of the FLI to detect ultrasonographic fatty liver was assessed by analyzing the area under the receiver operating characteristic (AUROC) curve. Results Among the 29,797 subjects enrolled in this study, fatty liver was diagnosed in 44.5% of the population. Subjects with ultrasonographic fatty liver had a significantly higher FLI than those without fatty liver by multivariate analysis (odds ratio 1.045; 95% confidence interval, CI 1.044–1.047, pfatty liver (AUROC: 0.827, 95% confidence interval, 0.822–0.831). An FLI fatty liver. Moreover, an FLI ≥ 35 (positive likelihood ratio (LR+) 3.12) for males and ≥ 20 (LR+ 4.43) for females rule in ultrasonographic fatty liver. Conclusions FLI could accurately identify ultrasonographic fatty liver in a large-scale population in Taiwan but with lower cut-off value than the Western population. Meanwhile the cut-off value was lower in females than in males. PMID:25781622

  5. Using Serial and Discrete Digit Naming to Unravel Word Reading Processes.

    During reading acquisition, word recognition is assumed to undergo a developmental shift from slow serial/sublexical processing of letter strings to fast parallel processing of whole word forms. This shift has been proposed to be detected by examining the size of the relationship between serial- and discrete-trial versions of word reading and rapid naming tasks. Specifically, a strong association between serial naming of symbols and single word reading suggests that words are processed serially, whereas a strong association between discrete naming of symbols and single word reading suggests that words are processed in parallel as wholes. In this study, 429 Grade 1, 3, and 5 English-speaking Canadian children were tested on serial and discrete digit naming and word reading. Across grades, single word reading was more strongly associated with discrete naming than with serial naming of digits, indicating that short high-frequency words are processed as whole units early in the development of reading ability in English. In contrast, serial naming was not a unique predictor of single word reading across grades, suggesting that within-word sequential processing was not required for the successful recognition for this set of words. Factor mixture analysis revealed that our participants could be clustered into two classes, namely beginning and more advanced readers. Serial naming uniquely predicted single word reading only among the first class of readers, indicating that novice readers rely on a serial strategy to decode words. Yet, a considerable proportion of Grade 1 students were assigned to the second class, evidently being able to process short high-frequency words as unitized symbols. We consider these findings together with those from previous studies to challenge the hypothesis of a binary distinction between serial/sublexical and parallel/lexical processing in word reading. We argue instead that sequential processing in word reading operates on a continuum

    Anterior knee pain is a common presenting complaint amongst adolescent athletes. We hypothesised that patellar tendinopathy may occur at a younger age than is generally recognised. Thus, we studied the patellar tendons in 134 elite 14- to 18-year-old female (n=64) and male (n=70) basketball players and 29 control swimmers (17 female, 12 male) clinically and with ultrasonography. We found that of 268 tendons, 19 (7%) had current patellar tendinopathy on clinical grounds (11% in males, 2% in females). Twenty-six percent of the basketball players' patellar tendons contained an ultrasonographic hypoechoic region. Ultrasonographic abnormality was more prevalent in the oldest tertile of players (17-18 years) than the youngest tertile (14-15.9 years). Of tendons categorised clinically as 'Never patellar tendinopathy', 22% had an ultrasonographic hypoechoic region nevertheless. This study indicates that patellar tendinopathy can occur in 14- to 18-year-old basketball players. Ultrasonographic tendon abnormality is 3 times as common as clinical symptoms.

    Full Text Available A B-mode ultrasonography (SCANNER 450 (5MHz, Pie Medical, Netherlands was used either alone or associated with laboratorial and radiographic examinations in 33 bitches with clinical diagnosis of pyometra. The increased uterus appeared as a well defined tubular structure with diameter ranging from 0.5 up to 4.0 cm. The uterine lumen was less echoic than the wall, with evident echoic shinings. There was an accordance between the increasing in the viscosity of the vaginal secretion and the echoigenicity. The ultrasonographic diagnosis was possible in 31 bitches (94% confirmed by laparotomy and autopsy. The B-mode ultrasonography can be used in the diagnosis of bitches with pyometra.

    Objectives This study aimed to describe the ultrasonographic, endoscopic and histological characteristics of the caecum and ileocaecocolic junction in cats suffering from chronic clinical signs compatible with caecocolic disease. Methods Cats presenting with clinical signs suggestive of a caecocolic disease were prospectively recruited. All cats underwent an ultrasonographic examination of the caecum, ileum, colon, ileocolic lymph nodes and local mesenteric fat, in addition to comprehensive abdominal ultrasonography. This was followed by a colonoscopy with a macroscopic assessment of the caecocolic mucosa; caecocolic tissue samples were systematically collected for histologic analysis. Results Eighteen cats were included. Eleven of 18 cats had ultrasonographic abnormalities adjacent to the ileocaecocolic junction (lymphadenopathy, local steatitis) and 13/18 cats had abnormalities directly related to the junction (wall thickening, loss of wall layering). Seventeen of 18 cats had at least one ultrasonographic abnormality. Endoscopically, hyperaemia, oedema, discoloration and/or erosions were found in all cats. Each cat was classified as having mild or moderate-to-severe lesions according to endoscopic results; no classification could be established statistically for ultrasonographic results. The accentuation of the dimpled pattern tended to be inversely related to the severity of endoscopic lesion scoring. Histologically, a large proportion of cats showed typhlitis (13/16), one had lymphoma and two were normal. All cats with typhlitis also had colitis. There was only slight agreement between endoscopic and histological caecal results regarding the severity of lesions. Loss of caecal wall layering on ultrasound was found in 7/18 cats and, surprisingly, did not appear as a reliable predictor of the severity of inflammation or of malignancy; neither did local steatitis nor lymph node size. Conclusions and relevance Ultrasonography and endoscopy should not be used as the

    Abstract Rationale: Primary leiomyosarcoma (LMS) of the vein is a rare tumor that arises from the smooth muscle cells of the vessel wall and has an extremely poor prognosis. This tumor can occur in vessels such as the inferior vena cava, great saphenous vein, femoral vein, iliac vein, popliteal vein, and renal vein; the inferior vena cava is the most common site. LMS of the femoral vein can result in edema and pain in the lower extremity; therefore, it is not easy to be differentiated from deep vein thrombosis (DVT). Moreover, virtually no studies have described the ultrasonographic features of LMS of the vein in detail. Patient concerns: We present a case of a 55-year-old woman with LMS of the left femoral vein that was misdiagnosed as having deep vein thrombosis (DVT) on initial ultrasonographic examination. The patient began to experience edema and pain in her left leg seven months previously. She was diagnosed as having DVT on initial ultrasonographic examination, but the DVT treatment that she had received for 7 months failed to improve the status of her left lower limb. Diagnoses: She subsequently underwent re-examination by means of a multimodal ultrasonographic imaging approach (regular B-mode imaging, color Doppler imaging, pulsed-wave Doppler imaging, contrast-enhanced ultrasonography), which confirmed a diagnosis of LMS. Interventions: This patient was treated successfully with surgery. Outcomes: This case demonstrates that use of multiple ultrasonographic imaging techniques can be helpful to diagnose LMS accurately. Detection of vasculature in a dilated vein filled with a heterogeneous hypoechoic substance on ultrasonography is a sign of a tumor. Lessons: The pitfall of misdiagnosing this tumor as DVT is a useful reminder. PMID:29145269

    This study was done retrospectively to analyze the ultrasonographic (US) findings in thyroid scintigraphic hot areas (HA). Three-thousand, eight-hundred and thirty-nine consecutive patients who underwent {sup 99m}Tc-pertechnetate (n=3435) or {sup 123}I (n=457) scintigraphy were analyzed. HA were regarded as present when the tracer concentration was greater than the remaining thyroid tissue, or when hemilobar uptake was observed. High-resolution US examinations were performed with a real-time electronic linear scanner with a 7.5 or 10 MHz transducer. One hundred and four (2.7%) were found to be scintigraphic HA (n=120). US revealed a nodular lesion or well-demarcated thyroid tissue corresponding to the HA in 94 areas (78.4%, Category 1), an ill-defined region with different echogenicity in 13 areas (10.8%, Category 2), and no correlating lesion in 13 areas (10.8%, Category 3). These 104 patients included 43 with adenomatous goiter (59 areas), 33 with adenoma, 11 with Hashimoto's thyroiditis, 5 with primary thyroid cancer, 4 with euthyroid ophthalmic Graves' disease (EOG), 3 with hemilobar atrophy or hypogenesis, 2 with hemilobar agenesis, 2 with hypothyroidism with blocking-type TSH-receptor antibodies (TSHRAb), 1 with acute suppurative thyroiditis. Among the 59 adenomatous nodules and 33 adenomas, 51 (86.4%) and 32 (97.0%), respectively, belonged to Category 1. A solitary toxic nodule was significantly larger and occurs more often in older patients than in younger patients. On the other hand, all 17 patients with known autoimmune thyroid diseases including Hashimoto's thyroiditis, EOG and hypothyroidism with blocking TSHRAb belonged to Category 2 or 3. Possible underlying mechanisms are hyperfunctioning tumors or nodules, localized functioning thyroid tissue freed from autoimmune destruction, inflammation or tumor invasion, congenital abnormality, clusters of hyperactive follicular cells caused by long-term TSH and/or TSHRAb stimulation, asymmetry

    Full Text Available Objective To find the nature of tendon involvement in chronic kidney disease (CKD patients on regular hemodialysis (RD, and its relationship to parathyroid hormone (PTH level using ultrasonography (US. Method A total of 50 CKD patients on RD subjected to musculoskeletal examination of knee and ankle, laboratory evaluation, and US of quadriceps tendon and Achilles tendon were involved. Results Ankle joint tenderness was the most frequent sign on examination. US of the Achilles tendons showed tenderness during probing in 44% patients, calcific deposition in 24% patients, abnormal peritendon tissue in 20% patients, and abnormal anteroposterior (A-P middle and distal one-third thicknesses of the Achilles tendon in 20% and 18% patients, respectively. PTH positively correlated with the duration of dialysis, serum phosphorus level, presence of calcific deposit, and increased thickness of the Achilles tendon. Conclusion The most common ultrasonographic finding in CKD patients on RD was Achilles tendon tenderness during probing. PTH level positively correlated with the duration of dialysis, presence of calcific deposit, and increased thickness of Achilles tendon.

    This study aimed to assess the sensitivity and specificity of ultrasonographic features of gout in intercritical and chronic stages and compared ultrasonographic features of gout between patients with persistent high serum uric acid (SUA) and patients with low SUA. Adult patients with gout confirmed by demonstration of monosodium urate crystals were recruited, if they were in intercritical or chronic stage clinically. Ultrasonographic examination of the first metatarsophalangeal joints (MTPJs) and the knee joints of both sides were done by a blinded rheumatologist trained in musculoskeletal ultrasound. Sixty-two patients with gout and 30 control subjects were examined. The double contour sign (DCS) was found in 71 (57.3%) first MTPJs and tophi were found in 54 (43.5%) first MTPJs. DCS was present in 43 (69.4%) gout patients but none in the control group (P gout patients were 69.4% (56.4-80.4%) and 100% (88.3-100%), respectively, while of tophi they were 66.1% (53-77.7%) and 100% (88.3-100%), respectively. The sensitivity of DCS increased to 100% in high the SUA subgroup (SUA ≥ 7 mg/dL). The low SUA (SUA gout subgroup showed significantly higher occurrence of erosions (40%) and tophi (50%) in first MTP joints than the control group. MSUS is useful for diagnosis of gout in intercritical or chronic stages, especially in patients with persistently high SUA level. © 2016 Asia Pacific League of Associations for Rheumatology and John Wiley & Sons Australia, Ltd.

    In this study, we examined mechanisms that underlie free-recall performance in bilinguals' first language (L1) and second language (L2) through the prism of serial-position effects. On free-recall tasks, a typical pattern of performance follows a U-shaped serial-position curve, where items from the beginning of the list (the primacy effect) and items from the end of the list (the recency effect) are recalled with higher accuracy than items from the middle of the list. The present study contrasted serial-position effects on the free-recall task in Korean-English bilinguals' L1 vs. L2 and examined the relationship between an independent working memory (WM) measure and serial-position effects in bilinguals' two languages. Results revealed stronger pre-recency (primacy and middle) effects in L1 than in L2, but similar recency effects in the two languages. A close association was observed between WM and recall performance in the pre-recency region in the L1 but not in the L2. Together, these findings suggest that linguistic knowledge constrains free-recall performance in bilinguals, but only in the pre-recency region.

    Ultrasonographic appearance of unorganized hyperechoic striations (UHS) has been observed in the canine gastric muscularis layer. The purpose of the study was to determine the prevalence, sonographic and postmortem histologic features, and to determine the clinical significance of canine gastric muscularis UHS. In the prospective study, 72 dogs were included. The presence of gastric muscularis UHS were reviewed to determine its distribution and location. In the retrospective study, 167 dogs that had both abdominal ultrasonography and necropsy were included. The prevalence of gastric muscularis UHS in dogs was 37.5% in the prospective and 5.4% in the retrospective studies respectively. The higher prevalence in prospective study was due to greater anticipation by the radiologists in search for gastric muscularis UHS. In the ventral gastric wall, the muscularis UHS were better defined when the gastric lumen was empty or non-distended, and were mostly parallel with the serosa when the gastric wall was distended (with gas or fluid). Visualization of the dorsal gastric wall was often obscured by gas shadowing from luminal gas. Histopathology was performed on eight dogs with gastric muscularis UHS, three of which had fibrous tissue observed with Masson's trichrome stain. Presence of gastric muscularis UHS in dogs may have been attributable to presence of incomplete interfaces between the inner oblique, middle circular and outer longitudinal layers of the gastric tunica muscularis or due to presence of fibrous tissue within the gastric muscularis layer. The clinical significance of canine gastric muscularis UHS is uncertain.

    The aims of this study were to investigate the accuracy of using the taller-than-wide (TTW) sign in two ultrasonographic planes to predict thyroid microcarcinoma, and to confirm the hypothesis that the presence of a TTW sign in both the transverse and longitudinal ultrasonographic planes strongly suggests thyroid microcarcinoma. Nine hundred forty-two thyroid nodules ≤1 cm were submitted to surgical-histopathologic and ultrasonographic examination. TTW signs were divided into three types based on their detection only in the transverse plane (TTTW type, n = 100), only in the longitudinal plane (LTTW type, n = 61) or in both planes (BTTW type, n = 131). The areas under the receiver operating characteristic curves (A(z)) for the three different TTW signs, as well as for the combination of all TTW signs (ATTW, n = 292), were compared. The results indicated that the A(z) values of the TTTW, LTTW, BTTW and ATTW signs in predicting thyroid microcarcinoma were 0.544, 0.531, 0.627 and 0.702, respectively. The ATTW sign was the most accurate (p 0.05). Therefore, both the LTTW and TTTW signs are reliable markers of thyroid microcarcinoma. The BTTW sign strongly suggests thyroid microcarcinoma.

    We present the case of a patient under study due to ascites in which a mass located on the gastric wall was observed during ultrasonography. Further studies (upper endoscopy and computed tomography) confirmed this finding. After an ultrasound-guided percutaneous biopsy, diagnosis of gastric schwannoma was made as intense S-100 expression was found. Surgery was rejected due to the bad clinical situation of the patient and because the mass was an asymptomatic benign tumor.

    Prospective study. To prospectively assess the incidence of dysphagia and to present the serial changes of each finding in the videofluoroscopic swallow study (VFSS) after anterior cervical discectomy and fusion (ACDF). The reported incidence of dysphagia after ACDF has varied widely, and the serial changes of dysphagia using VFSS have not been clearly determined yet. Data of 47 patients preoperatively and at 1 week and 1 month postoperatively were used for the analyses. The Bazaz dysphagia score and VFSS were checked preoperatively and at 1 week and 1 month postoperatively. The presence of aspiration or penetration, amount of vallecular and pyriform sinus residues, functional dysphagia scale, temporal parameters of oral transit time, pharyngeal transit time, and pharyngeal delay time (PDT) were evaluated from the VFSS data. Incidences of dysphagia measured by the Bazaz dysphagia score were 83.0% at 1 week and 59.6% at 1 month after ACDF. Although the incidence of aspiration was 4.3% and the incidence of penetration was 36.2% at 1 week and 25.5% at 1 month after surgery, none of the patients had aspiration pneumonia. The number of patients with vallecular and pyriform sinus residues significantly increased after ACDF. Further, there were no statistically significant changes at all time points in terms of oral transit time, pharyngeal transit time, and pharyngeal delay time. Dysphagia is common until 1 month after ACDF. Although the incidence of aspiration or penetration in VFSS after ACDF was high, no patient had aspiration pneumonia, which may be because of the intact neurological swallowing mechanism. The typical pattern of dysphagia after ACDF included vallecular and pyriform sinuses filled with postswallow residue, which may result from soft tissue edema and weak constriction of pharyngeal muscles after ACDF.

    Full Text Available Objective: To investigate ankle tenosynovitis in rheumatoid arthritis patients, regarding its presence, the kind of tendon involved and the concordance between clinical and ultrasound findings. Methods: Twenty patients with rheumatoid arthritis and pain or swollen ankle joint were evaluated. Tendon involvement was evaluated with ultrasound imaging. The Health Assessment Questionnaire (HAQ was performed for disability evaluation. Age, sex, disease duration, and vocational activity levels were also obtained. The statistical analysis included Fisher’s exact test. The significance level was 0.05. Results: Tenosynovitis was found in 13 of 20 (65.0% patients in 19 joints, in which 6 were bilaterally (46.1% and unilateral in 7 (53.8%. Tibialis posterior tenosynovitis was seen in nine (45.0% patients, Achilles tenosynovitis in seven (35.0%, tibialis anterior tenosynovitis in three (15.0%, and peroneal tenosynovitis in three (15.0% patients. We found concordance between symptomatic ankle and ultrasonographic findings in 92.3% of the patients with tenosynovitis. Association between severe HAQ with tendon involvement was not found (p>0.05. Disease duration was not associated with tenosynovitis. Patients were predominantly older, female, with mean age around 50.8 years. The long disease duration of patients presented a mean of 11.4 years and, most of them, with no vocational activity (65.0%. Conclusions: The results indicate that ankle tenosynovitis is very common in rheumatoid arthritis patients, both unilateral and bilateral. Tibialis posterior was the most common tendon involvement found. Finally, we found concordance between the clinical and ultrasound findings in almost all rheumatoid arthritis patients with ankle tenosynovitis.

    To determine the accuracy of ultrasonographic diagnosis in patients with clinically suspected ureteral stones and to evaluate the factors influencing on the diagnostic sensitivity for the detection of ureteral stone. The patients (115 cases) with proven presence or absence of ureteral stones were included in the study. At first, both sided kidney and proximal ureters were examined on each decubitus position and then middle ureters were done if proximal ureters were visualized. On the supine view, distal ureters and UVJ were scanned through the acoustic window of the filled bladder. KUB (20 cases), IVU (62 cases), AGP (7 cases), RGP (3 cases), ESWL (9 cases), CT (9 cases), and patients' history of spontaneous passage of stones (5 cases) were included as confirmation methods. The sensitivity, specificity, and accuracy of the ultrasonographic diagnosis of ureteral stones were calculated and the factors influencing on the sensitivity on the focus of the position and size of ureteral stone, visibility of ureter, the presence or absence of renal stone and hydronephrosis were analyzed. Of 82 cases with proven ureteral stone, 72 cases were revealed on ultrasonography and there was one false positive examination among 33 cases with proven absence of ureteral stone. The overall diagnostic accuracy was 90%. The ultrasonographic detection rates of ureteral stones as correlated with their locations were 83% (24/29), 100% (11/11), 80% (16/20), and 100% (21/21) of each group of proximal, middle, distal ureter, and UVJ stones. Of 61 stones, those as correlated with their sizes, were 82% (37/45) and 94% (15/16) of each group less than 10 mm and more than 11 mm. Those as correlated with the presence or absence of ureteral visualization on ultrasonography were 92% (69/75) and 43% (3/7) of each group. Those as correlated with presence of absence of renal stones were 85% (41/48) and 91% (31/34) of each group. Those as correlated with presence or absence of hydronephrosis were 89

    Aim: To describe serial changes in brain magnetic resonance imaging (MRI) in acute human infection from two outbreaks of Hendra virus (HeV), relate these changes to disease prognosis, and compare HeV encephalitis to reported cases of Nipah virus encephalitis. Materials and methods: The MRI images of three human cases (two of which were fatal) of acute HeV meningoencephalitis were reviewed. Results: Cortical selectivity early in the disease is evident in all three patients, while deep white matter involvement appears to be a late and possibly premorbid finding. This apparent early grey matter selectivity may be related to viral biology or ribavirin pharmacokinetics. Neuronal loss is evident at MRI, and the rate of progression of MRI abnormalities can predict the outcome of the infection. In both fatal cases, the serial changes in the MRI picture mirrored the clinical course. Conclusion: This is the first comprehensive report of serial MRI findings in acute human cerebral HeV infection from two outbreaks. The cortical selectivity appears to be an early finding while deep white matter involvement a late, and possibly premorbid, finding. In both fatal cases, the serial changes in MRI mirrored the clinical course.

Neuronal loss is evident at MRI, and the rate of progression of MRI abnormalities can predict the outcome of the infection. In both fatal cases, the serial changes in the MRI picture mirrored the clinical course. Conclusion: This is the first comprehensive report of serial MRI findings in acute human cerebral HeV infection from two outbreaks. The cortical selectivity appears to be an early finding while deep white matter involvement a late, and possibly premorbid, finding. In both fatal cases, the serial changes in MRI mirrored the clinical course.

    We performed serial single-photon emission CT (SPECT) with N-isopropyl-p-( 123 I)-Iodoamphetamine to measure the regional cerebral blood flow (rCBF) in 15 children with partial epilepsy. SPECT showed focal changes in 14 cases. Ten cases had abnormalities in the initial SPECT and another four cases in the second test. The cases with normal rCBF in initial SPECT had been tested in an early phase after the onset, and then decreased rCBF were observed in the second SPECT. The cases with both abnormal rCBF in the initial SPECT and improved rCBF in the second SPECT showed good prognosis in clinico-electrophysiological evolutions. In cases with abnormal changes of rCBF in the second SPECT, clinical prognosis was found to be not so good. These findings suggest that serial SPECT may be used to follow the course of epilepsy.

    Models of short-term memory for sequential information rely on item-level, feature-based descriptions to account for errors in serial recall. Transposition errors within alternating similar/dissimilar letter sequences derive from interactions between overlapping features. However, in two experiments, we demonstrated that the characteristics of the sequence are what determine the fates of items, rather than the properties ascribed to the items themselves. Performance in alternating sequences is determined by the way that the sequences themselves induce particular prosodic rehearsal patterns, and not by the nature of the items per se. In a serial recall task, the shapes of the canonical "saw-tooth" serial position curves and transposition error probabilities at successive input-output distances were modulated by subvocal rehearsal strategies, despite all item-based parameters being held constant. We replicated this finding using nonalternating lists, thus demonstrating that transpositions are substantially influenced by prosodic features-such as stress-that emerge during subvocal rehearsal.

    Large ovarian cysts are conventionally treated by laparotomy. We describe a technique of transabdominal drainage under ultrasonographic control followed by laparoscopic excision of an ovarian cyst that was 24 x 10 x 20 cm. This approach has the benefits of minimal-access surgery and is suitable for unilocular benign cysts of any size.

    Male breast cancer is very rare, with the incidence of 0.15-1% of all breast cancers and less than 1% of all cancers in men. The prognosis of male breast cancer is poorer than that of female because the median age of detection of the disease is in more late stage. It usually involves higher axillary lymph nodes. We report two case of male breast cancer to describe characteristic mammographic and ultrasonographic findings and to compare with the findings of gynaecomastia.

    2009-10-01

    The use of ultrasonographic guidance for regional anaesthesia has known recently a big interest in children in recent years. The linear ultrasound probes with a 25 mm active surface area (or probes with 38 mm active surface area in older children), with high sound frequencies in the range 8-14 MHz, allow a good compromise between excellent resolution for superficial structure and good penetration depths. In children, the easiest ultrasound guided blocks are axillar blocks, femoral blocks, fascia iliaca compartment blocks, ilio-inguinal blocks and para-umbilical blocks, caudal blocks. They permit a safe and easy learning curve of these techniques. The main advantage of ultrasound guided regional anaesthesia is the visualization of different anatomical structures and the approximate localization of the tip of needle. The other advantages for ultrasound guided peripheral nerve blocks in children are: faster onset time of sensory and motor block, longer duration of sensory blockade, increase of blockade quality and reduction of local anesthetic injection. The use of ultrasonographic guidance for central block allows to visualize different structures as well as spine and his content. Spinous process, ligament flavum, dura mater, conus medullaris and cerebrospinal fluid are identifiable, and give some information on spine, epidural space and the depth between epidural space and skin. At last, in caudal block, ultrasounds permit to evaluate the anatomy of caudal epidural space, especially the relation of the sacral hiatus to the dural sac and the search of occult spinal dysraphism. Benefit of this technique is the visualization of targeted nerves or spaces and the spread of injected local anaesthetic.

  15. Auditory distraction and serial memory: The avoidable and the ineluctable

    Directory of Open Access Journals (Sweden)

    2010-01-01

    Full Text Available One mental activity that is very vulnerable to auditory distraction is serial recall. This review of the contemporary findings relating to serial recall charts the key determinants of distraction. It is evident that there is one form of distraction that is a joint product of the cognitive characteristics of the task and of the obligatory cognitive processing of the sound. For sequences of sound, distraction appears to be an ineluctable product of similarity-of-process, specifically, the serial order processing of the visually presented items and the serial order coding that is the by-product of the streaming of the sound. However, recently emerging work shows that the distraction from a single sound (one deviating from a prevailing sequence results in attentional capture and is qualitatively distinct from that of a sequence in being restricted in its action to encoding, not to rehearsal of list members. Capture is also sensitive to the sensory task load, suggesting that it is subject to top-down control and therefore avoidable. These two forms of distraction-conflict of process and attentional capture-may be two consequences of auditory perceptual organization processes that serve to strike the optimal balance between attentional selectivity and distractability.

    The aim of this study was to compare ultrasonographic features in patients with lymphocytic thyroiditis (LT) and papillary thyroid carcinoma (PTC) having suspicious thyroid nodule(s) in a background of heterogeneous parenchyma and to determine the clinical and radiological predictors of malignancy. We reviewed the cases of 100 patients who underwent ultrasonography between April 2011 and October 2012, and showed suspicious thyroid nodule(s) in a background of heterogeneous parenchyma. Eight patients who did not undergo ultrasonography-guided fineneedle aspiration cytology (FNAC) and 34 cases of follow-up ultrasonography after initial FNAC were excluded. We compared the benign and malignant nodules in terms of their clinical and radiological factors. For the 58 nodules including 31 LTs (53.4%) and 27 PTCs (46.6%), the mean tumor sizes of the two groups were 0.96 cm for LT and 0.97 cm for PTC. A univariate analysis revealed that PTCs were more frequent in patients younger than 45 years and having microcalcifications than was LT. An independent predictor of PTC after adjustment was an age of <45 years. LT mimics malignancy in a background of heterogeneous parenchyma on ultrasonography. A young age of <45 years is the most important predictor of malignancy in this condition.

    The ring-tailed lemur (Lemur catta) is primarily distributed in south and southwestern Madagascar. It is classified as an endangered species by the International Union for Conservation of Nature. Various abdominal diseases, such as hepatic lipidosis, intestinal ulcers, cystitis, urinary tract obstruction, and neoplasia (e.g., colonic adenocarcinoma and cholangiocarcinoma), have been reported in this species. The aim of this study was to describe the normal radiographic and ultrasonographic abdominal anatomy in captive ring-tailed lemurs to provide guidance for clinical use. Radiography of the abdomen and ultrasonography of the liver, spleen, kidneys, and urinary bladder were performed in 13 and 9 healthy captive ring-tailed lemurs, respectively, during their annual health examinations. Normal radiographic and ultrasonographic reference ranges for abdominal organs were established and ratios were calculated. The majority (12/13) of animals had seven lumbar vertebrae. The sacrum had mainly (12/13) three segments. Abdominal serosal detail was excellent in all animals, and hypaxial muscles were conspicuous in the majority (11/13) of animals. The spleen was frequently (12/13) seen on the ventrodorsal (VD) view and rarely (3/13) on the right lateral (RL) view. The liver was less prominent and well contained within the ribcage. The pylorus was mostly (11/13) located to the right of the midline. The right and left kidneys were visible on the RL and VD views, with the right kidney positioned more cranial and dorsal to the left kidney. On ultrasonography, the kidneys appeared ovoid on transverse and longitudinal views. The medulla was hypoechoic to the renal cortex. The renal cortex was frequently (8/9) isoechoic and rarely (1/9) hyperechoic to the splenic parenchyma. The liver parenchyma was hypoechoic (5/5) to the renal cortex. Knowledge of the normal radiographic and ultrasonographic abdominal anatomy of ring-tailed lemurs may be useful in the diagnosis of diseases and in

    Empirical research on serial murder is limited due to the lack of consensus on a definition, the continued use of primarily descriptive statistics, and linkage to popular culture depictions. These limitations also inhibit our understanding of these offenders and affect credibility in the field of research. Therefore, this comprehensive overview of a sample of 508 cases (738 total offenders, including partnered groups of two or more offenders) provides analyses of solo male, solo female, and partnered serial killers to elucidate statistical differences and similarities in offending and adjudication patterns among the three groups. This analysis of serial homicide offenders not only supports previous research on offending patterns present in the serial homicide literature but also reveals that empirically based analyses can enhance our understanding beyond traditional case studies and descriptive statistics. Further research based on these empirical analyses can aid in the development of more accurate classifications and definitions of serial murderers.

    The aims of this retrospective study were to identify clinical cases of dogs with appendicular osteosarcoma (OSA) in which hepatic metastasis was confirmed, to highlight the use of cytology for its diagnosis and to describe the radiographic and ultrasonographic appearances of the lesion. Medical records were retrospectively reviewed for dogs with appendicular OSA and hepatic metastases between January 2005 and January 2013. Reviews of radiographs, ultrasounds and cytology were performed. Six dogs with appendicular OSA and hepatic metastases were identified. The ultrasonographic appearance of metastatic lesions varied, including hyperechoic with shadowing, hyperechoic without shadowing, hypoechoic and mixed echogenicity. In two cases, the hepatic metastases were also evident on thoracic radiographs. The mean survival time from diagnosis of appendicular OSA was 188 days (range 69-363 days) and from diagnosis of hepatic metastases was 35 days (range 2-69 days). Death was tumour-related in all cases. Hepatic metastasis varies widely in its ultrasonographic appearance. In three of six cases, hepatic metastasis was identified without concurrent pulmonary metastasis; therefore, abdominal ultrasound may be useful at regular intervals for patient evaluation, especially in clinical trials where accurate identification of the disease-free interval is crucial. Once hepatic metastasis is confirmed, survival times appear limited. © 2016 Australian Veterinary Association.

    To describe ultrasonographic findings of ovarian granulosa cell tumor (GCT) and to determine their possible value in the differential diagnosis of ovarian tumors. Sonographic appearances of ten cases of pathologically proven GC Ts were retrospectively reviewed regarding their location, size, outer margin, the echo pattern of the tumor, endometrial thickness, presence of ascites, and metastasis to adjacent tissue or distant sites. 3.0-3.5 MHz trans-abdominal US or 5.0-6.5 MHz transvaginal US were used. The sonographic features could be classified as follows: unilocular cystic mass without nodule or septation (type 1), multilocular cystic mass (type 2), and solid mass (type 3). Pathologically nine cases were adult type granulosa cell tumors (GCT) and one was a juvenile type. All cases were unilateral. GCT arising from left ovary were seven, right, three. The largest diameter of the tumors ranged from 6.8 to 24 cm (mean: 11.9 cm). All had well-defined margins. Ascites was seen in four cases. Among ten cases of GCT, six were mainly solid (type 3). One case manifested as a unilocular cystic mass without mural nodule or septation. Three were multilocular cystic masses and no mural nodule was found in all three cases. Metastases to peritoneum and lymph nodes was seen in one case. The ultrasonographic findings of GCT are various but combined with clinical and laboratory findings they could be helpful in the differential diagnosis of ovarian tumors.

    Primary leiomyosarcoma (LMS) of the vein is a rare tumor that arises from the smooth muscle cells of the vessel wall and has an extremely poor prognosis. This tumor can occur in vessels such as the inferior vena cava, great saphenous vein, femoral vein, iliac vein, popliteal vein, and renal vein; the inferior vena cava is the most common site. LMS of the femoral vein can result in edema and pain in the lower extremity; therefore, it is not easy to be differentiated from deep vein thrombosis (DVT). Moreover, virtually no studies have described the ultrasonographic features of LMS of the vein in detail. We present a case of a 55-year-old woman with LMS of the left femoral vein that was misdiagnosed as having deep vein thrombosis (DVT) on initial ultrasonographic examination. The patient began to experience edema and pain in her left leg seven months previously. She was diagnosed as having DVT on initial ultrasonographic examination, but the DVT treatment that she had received for 7 months failed to improve the status of her left lower limb. She subsequently underwent re-examination by means of a multimodal ultrasonographic imaging approach (regular B-mode imaging, color Doppler imaging, pulsed-wave Doppler imaging, contrast-enhanced ultrasonography), which confirmed a diagnosis of LMS. This patient was treated successfully with surgery. This case demonstrates that use of multiple ultrasonographic imaging techniques can be helpful to diagnose LMS accurately. Detection of vasculature in a dilated vein filled with a heterogeneous hypoechoic substance on ultrasonography is a sign of a tumor. The pitfall of misdiagnosing this tumor as DVT is a useful reminder.

    The normal pattern of performance on list-learning tasks is to recall more words from the beginning (primacy) and end (recency) of the list. This pattern is also seen in patients with closed head injury, but malingerers tend to recall less words from the beginning of word lists, leading to a suppressed primacy effect. The present study examined this pattern on both learning trials and delayed recall of the Auditory Verbal Learning Test (AVLT) in 34 persons performing with normal effort, 38 naive malingerers, 33 warned malingerers, and 29 head-injured patients. Both malingering groups had lower scores on the primacy portion of the list during learning trials, while normals and head-injured patients had normal serial position curves. During delayed recall, normals and head-injured patients did better than the two malingering groups on middle and recency portions of the list. Findings suggest that the serial position effect during learning trials may be a useful pattern of performance to watch for when suspicious of malingering.

    Recent findings suggest that Hebb repetition learning-a paradigmatic example of long-term serial-order learning-is impaired in adults with dyslexia. The current study further investigated the link between serial-order learning and reading using a longitudinal developmental design. With this aim, verbal and visual Hebb repetition learning performance and reading skills were assessed in 96 Dutch-speaking children who we followed from first through second grade of primary school. We observed a positive association between order learning capacities and reading ability as well as weaker Hebb learning performance in early readers with poor reading skills even at the onset of reading instruction. Hebb learning further predicted individual differences in later (nonword) reading skills. Finally, Hebb learning was shown to explain a significant part of the variance in reading performance above and beyond phonological awareness. These findings highlight the role of serial-order memory in reading ability. Copyright © 2015 Elsevier Inc. All rights reserved.

    To evaluate power Doppler ultrasonographic findings of the enlarged mesenteric lymph nodes, and to compare between patients with and without acute abdominal pain. Thirty seven children with acute abdominal pain and thirty three asymptomatic children all with the enlarged mesenteric lymph nodes in whom power Doppler ultrasonography was performed were included in this study. The enlarged lymph nodes were evaluated for number, size, shape (ratio of long to short axis diameter: L/S ratio), distribution and hilar vascularity on gray scale ultrasonography while the flow pattern (3 types; nonvascular, hilar, peripheral type) of the vascularity was analyzed with power Doppler ultrasonography. The hilar pattern of vascular flow type was graded into I to III depending upon color signal. The comparison between symptomatic group and asymptomatic control group was analyzed with gray scale ultrasonography and power Doppler ultrasonography. The number of enlarged lymph nodes (n≥10) was greater in the symptomatic group (29/37, 78%) than in the control group (6/33, 18%) (p<0.01). The mean size of the largest lymph node between two groups was different with a statistical significance; the mean long diameter was 12.4 ± 3.1 mm (short diameter 5.8 ± 1.6 mm) in the symptomatic group and 11.2 ± 2.3 mm (4.5 ± 1.3 mm) in the control group (p<0.05). The mean L/S ratio of the largest one was 2.2 ± 0.6 in the symptomatic group and 2.7 ± 0.8 in the control group (p<0.05). Lymph nodes were detected in both right lower quadrant of the abdomen and periumblical region in 16 (43%) of the symptomatic group and 3 (9%) of the control group (p<0.01). On power Doppler ultrasonography, hilar type of vascularity was noted in 22 (67%) cases of the control group and all of symptomatic group. The prevalence of exuberant hilar flows (grade II/III) in the symptomatic group (28/37, 76%) was significantly higher than that of the control group (4/33,12%) (p<0.01).

    It has been proposed that the metrics of space, time and other magnitudes relevant for action are coupled through a generalized magnitude system that also contribute to number representation. Several studies capitalized on stimulus-response compatibility effects to show that numbers map onto left-right representations and grasp representations as a function of their magnitude. However, the tasks typically used do not allow disentangling magnitude from serial order processing. Here, we devised a working memory (WM) task where participants had to remember random sequences of numbers and perform a precision/whole-hand grip (Experiment 1) or a uni-manual left/right button press (Experiment 2) in response to numbers presented during the retention interval. This task does allow differentiating the interference of number magnitude and serial order with each set of responses. Experiment 1 showed that precision grips were initiated faster than whole-hand grips in response to small numbers, irrespective of their serial position in WM. In contrast, Experiment 2 revealed an advantage of right over left button presses as serial position increased, without any influence of number magnitude. These findings demonstrate that grasping and left-right movements overlap with distinct dimensions of number processing. These findings are discussed in the light of different theories explaining the interactions between numbers, space and action.

    Ahmed M. Maged

    2013-09-01

    Conclusion: CA125, β HCG and progesterone are good biochemical markers and FHR and CRL are good ultrasonographic markers for the prediction of outcome in women with threatened abortion. FHR at 110 bpm gives the best predictivity followed by serum P at 25 ng/ml, β HCG at 19887 mIU/ml, CA 125 at 80 IU/ml and CRL at 21 mm with the least predictive accuracy among studied markers. Adding serum progesterone to FHR gave a sensitivity and specificity of 100%.

    The aim was to test the accuracy of calibrated digital analysis of ultrasonographic hepatic images for diagnosing fatty liver in dairy cows. Digital analysis was performed by means of a novel method, computer-aided ultrasound diagnosis (CAUS), previously published by the authors. This method implies a set of pre- and postprocessing steps to normalize and correct the transcutaneous ultrasonographic images. Transcutaneous hepatic ultrasonography was performed before surgical correction on 151 German Holstein dairy cows (mean +/- standard error of the means; body weight: 571+/-7 kg; age: 4.9+/-0.2 yr; DIM: 35+/-5) with left-sided abomasal displacement. Concentration of triacylglycerol (TAG) was biochemically determined in liver samples collected via biopsy and values were considered the gold standard to which ultrasound estimates were compared. According to histopathologic examination of biopsies, none of the cows suffered from hepatic disorders other than hepatic lipidosis. Hepatic TAG concentrations ranged from 4.6 to 292.4 mg/g of liver fresh weight (FW). High correlations were found between the hepatic TAG and mean echo level (r=0.59) and residual attenuation (ResAtt; r=0.80) obtained in ultrasonographic imaging. High correlation existed between ResAtt and mean echo level (r=0.76). The 151 studied cows were split randomly into a training set of 76 cows and a test set of 75 cows. Based on the data from the training set, ResAtt was statistically selected by means of stepwise multiple regression analysis for hepatic TAG prediction (R(2)=0.69). Then, using the predicted TAG data of the test set, receiver operating characteristic analysis was performed to summarize the accuracy and predictive potential of the differentiation between various measured hepatic TAG values, based on TAG predicted from the regression formula. The area under the curve values of the receiver operating characteristic based on the regression equation were 0.94 (or=50mg of TAG/g of FW), 0.83 (or

For a recent 21-month period, ninety three living donor candidates who underwent both preoperative US and parenchymal biopsy of the liver were consecutively selected. FL was ultrasonographically graded using the well-known three-Point grading system (ie, mild, moderate and severe degrees) whereas histologic grade of FL was divided into minimal ( 60%) degrees depending upon the percentages of each of macrovesicular, microvesicular and total fat-containing hepatocytes. US grade and histologic grade of FL in each patient were retrospectively correlated according to the US and pathologic records in their databases. Statistical analysis was conducted with the chi-square test and linear by linear association. US findings included the normal liver, mild FL, and moderate FL in 63, 23 and 7 patients, respectively. Analyzed with the total fat content, 38 of 63 patients (60%) whose US finding was normal proved to have FL of various histologic grades. Meanwhile, US grade of FL correlated well with the histologic grade in 16 (53%) of 30 patients who showed mild or moderate FL on US, and in the remaining patients, US grade was more commonly underestimated compared to the histologic grade. All patients with moderate FL on US Proved to have either moderate or severe FL at histology. US grade statistically correlated well with the histologic grade classified by either the total or macrovesicular fat contents (p<.001) while a poor correlation was seen when histologic grade using the microvesicular fat content was used. The well-known qualitative US grading system of fatty liver seems to show a relatively good correlation with the histologic grade, but it has a tendency to underestimate compared to the

    Serial killers are important in American horror because of their ability to exist between ‘myth’ and ‘reality’. The serial killer is one of the most important American myths, but it is one firmly rooted in real life: unlike Paul Bunyan or Superman, serial killers do exist. This essay examines the relationship between the ‘myth’ and the ‘reality’ of serial killers, and the complex relationship between the American public and the serial killer, using Henry: Portrait of a Serial K...

  14. Reliability of ultrasonographic measurements in suspected patients of developmental dysplasia of the hip and correlation with the acetabular index

    Full Text Available Background: Ultrasonography is accepted as a useful imaging modality in the early detection of developmental dysplasia of the hip (DDH. Early detection and early treatment of DDH prevents hip dislocation and related physical, social, economic, and psychological problems. The purpose of this study was to evaluate the reliability of ultrasonographic and roentgenographic measurements measured by seven different observers. Materials and Methods: The alpha angles of 66 hips in 33 patients were measured using the Graf method by seven different observers. Acetabular index degrees on plane roentgenograms were measured in order to assess the correlation between the ultrasonographic alpha angle and the radiographic acetabular index, which both show the bony acetabular depth, retrospectively. Results: The interclass correlation coefficient, measuring the interobserver reliability, was high and statistically significant for the ultrasonographic measurements. There was a negative correlation between the alpha angle and the acetabular index. Conclusions: Ultrasonography, when applied properly, is a reliable technique between different observers, in the diagnosis and follow up of DDH. When assessed concomitantly with the roentgenographic measurements, the results are reliable and statistically meaningful.

    To report clinical findings and outcome in a dog with gastrocnemius tendon strain treated with autologous mesenchymal stem cells and a custom orthosis. Clinical report. A 4-year-old spayed female Border Collie. Bone-marrow derived, autologous mesenchymal stem cells were transplanted into the tendon core lesion. A custom, progressive, dynamic orthosis was fit to the tarsus. Serial orthopedic examinations and ultrasonography as well as long-term force-plate gait analysis were utilized for follow up. Lameness subjectively resolved and peak vertical force increased from 43% to 92% of the contralateral pelvic limb. Serial ultrasonographic examinations revealed improved but incomplete restoration of normal linear fiber pattern of the gastrocnemius tendon. Findings suggest that autologous mesenchymal stem cell transplantation with custom, progressive, dynamic orthosis may be a viable, minimally invasive technique for treatment of calcaneal tendon injuries in dogs. © Copyright 2013 by The American College of Veterinary Surgeons.

    Hepatic fatty infiltration appears as an area of increased echogenicity. And many factors concerned to fatty infiltration. With 65 cases of fatty liver and 42 cases of normal group, we analyzed fatty liver with grading and attempt to find relations between grade of fatty liver and levels of body index, serum triglyceride, and serum lipid. And compared fatty liver with normal control group. Patients with fatty liver are higher percentage of supra-normal value in body index, serum lipid, and serum triglyceride than normal control group. As fatty infiltration progressed, serum lipid, serum trig-lyceride and body index are also increased. Conclusively ultrasonographic examination of liver with serum triglyceride, serum lipid, and body index are simple method, useful follow-up examination of fatty liver, and preventive routine check-up of chronic liver disease

    Shear-wave elastography (SWE) has the potential to improve diagnostic performance of conventional ultrasound (US) in differentiating benign from malignant breast masses. To investigate false positive or negative results of SWE in differentiating benign from malignant breast masses and to analyze clinical and imaging characteristics of the masses with false SWE findings. From May to October 2013, 166 breast lesions of 164 consecutive women (mean age, 45.3 ± 10.1 years) who had been scheduled for biopsy were included. Conventional US and SWE were performed in all women before biopsy. Clinical, ultrasonographic morphologic features and SWE parameters (pattern classification and standard deviation [SD]) were recorded and compared with the histopathology results. Patient and lesion factors in the "true" and "false" groups were compared. Of the 166 masses, 118 (71.1%) were benign and 48 (28.9%) were malignant. False SWE features were more frequently observed in benign masses. False positive rates of benign masses and false negative rates of malignancy were 53% and 8.2%, respectively, using SWE pattern analysis and were 22.4% and 10.3%, respectively, using SD values. A lesion boundary of the masses on US (P = 0.039) and younger patient age (P = 0.047) were significantly associated with false SWE findings. These clinical and ultrasonographic features need to be carefully evaluated in performance and interpretation of SWE examinations. © The Foundation Acta Radiologica 2014.

    There are various causes of calf pain. The differential diagnoses affecting the lower leg include cystic lesions, trauma-related lesions, infection or inflammation, vascular lesions, neoplasms, and miscellaneous entities. Ultrasound (US) provide detailed anatomical information of the calf structures, and it offers the ability to confirm, other calf abnormalities, particularly when deep vein thrombosis (DVT) is ruled out. The purpose of this article is to review the causes of a painful calf presenting as DVT and incidental findings found as part of the work-up of DVT, and to provide a broad overview of US findings and clinical features of these pathologies.

    1989-11-01

    To assess ultrasonography's capabilities in the detection of cancer and other diseases, abdominal ultrasonographic screening was performed for 3,707 Hiroshima and 2,294 Nagasaki atomic bomb survivors and comparison subjects who participated in the Adult Health Study from 1 November 1981 to 31 October 1985 in Hiroshima and from 1 August 1984 to 31 July 1986 in Nagasaki. A total of 20 cancers was detected, consisting of 7 hepatomas, 3 gastric cancers, 3 renal cancers, 2 cancers of the urinary bladder, and 1 cancer each of the ovary, pancreas, colon, ureter and liver (metastatic). The cancer detection rate was 0.33 %. The diagnoses of seven cancer subjects in each city were subsequently confirmed at autopsy or surgery; diagnoses of four cancer subjects in Hiroshima and two in Nagasaki were obtained from death certificates. Among the 20 cancer patients, 13 were asymptomatic. After the ultrasonographic detection and diagnosis of these 20 cancers, the medical records of each of the 20 cancer patients were reviewed for any evidence of cancer detection by other examining techniques, and the records of only 3 patients revealed such recent detection. The tumor and tissue registries were similarly checked, but no evidence of earlier diagnosis of their disease was found. Ten of the cancer patients had received ionizing radiation doses from the A-bombs ranging up to 3,421 mGy (DS86), but no correlation was established between cancer prevalence and the A-bomb doses. A variety of tumors, 259 in number and most probably benign, were also detected with ultrasonography. In addition, numerous other abnormalities were diagnosed, with prevalences of 7.7 % for cholelithiasis, 5.7 % for renal cysts, and 3.8 % for liver cysts. No statistical analysis was performed concerning the prevalence of the diseases detected. (author)

    Full Text Available Background: High-frequency ultrasound is a noninvasive tool that offers characteristic markers, quantifying the cutaneous changes of the physiological senescence process. Aims: The aim was to assess the changes in skin thickness, dermal density and echogenicity, as part of the ageing process, with different age intervals. Methods : The study was performed on 160 patients, aged 40.4 ± 21.2, divided into four age categories: <20, 21-40, 41-60, 61-80. Ultrasonographic images (Dermascan device were taken from three sites: dorsal forearm (DF, medial arm (MA, zygomatic area (ZA. We assessed the thickness of epidermis and dermis (mm, number of low, medium, high echogenicity pixels, the ratio between the echogenicity of the upper and lower dermis (LEPs/LEPi, and SLEB (subepidermal low echogenicity band. The statistical analysis was performed using SPSS 15.00. A P value <0.05 was considered significant. Results: On all examined sites, it was found that the dermal thickness increases in the 21 to 40 year interval (P<0.0001. After the 21 to 40 year interval, the number of low echogenic pixels increases significantly, especially on photoexposed sites. High-echogenic pixels follow the same pattern on all examined sites: they increase in the 21 to 40 year interval and decrease in the 3rd and 4th age category. The LEPs/LEPi ratio increases significantly with age, at all sites (P<0.05, due to an increase of hypoechogenic pixels in the upper dermis. Conclusions: High-frequency ultrasound is a noninvasive "histological" tool that can assess the cutaneous structure and age-related changes. It offers imagistic markers, comparable to the histological parameters and also characteristic ultrasonographic markers. Histology remains the gold standard for the investigation of the integumentary system.

    A serial communications system based on the EIA RS232-C standard with modem control lines has been developed. The DLV11-E interface is used for this purpose. All handshaking is done with the modem control lines. This allows totally independent full duplex communication. The message format consists of eight bit data with odd parity and a sixteen bit checksum on the whole message. All communications are fully interrupt driven. A program was written to load a program into a remote LSI-11 using the serial line without bootstrap ROM

  6. Evidence for spontaneous serial refreshing in verbal working memory?

    Vergauwe, Evie; Langerock, Naomi; Cowan, Nelson

    2018-04-01

    Working memory (WM) keeps information temporarily accessible for ongoing cognition. One proposed mechanism to keep information active in WM is refreshing. This mechanism is assumed to operate by bringing memory items into the focus of attention, thereby serially refreshing the content of WM. We report two experiments in which we examine evidence for the spontaneous occurrence of serial refreshing in verbal WM. Participants had to remember series of red letters, while black probe letters were presented between these memory items, with each probe to be judged present in or absent from the list presented so far, as quickly as possible (i.e., the probe-span task). Response times to the probes were used to infer the status of the representations in WM and, in particular, to examine whether the content of the focus of attention changed over time, as would be expected if serial refreshing occurs spontaneously during inter-item pauses. In sharp contrast with this hypothesis, our results indicate that the last-presented memory item remained in the focus of attention during the inter-item pauses of the probe-span task. We discuss how these findings help to define the boundary conditions of spontaneous refreshing of verbal material in WM, and discuss implications for verbal WM maintenance and forgetting.

    The practice of criminal psychological profiling is frequently cited as being applicable to serial arson crimes. Despite this claim, there does not appear to be any empirical research that examines serial arson offence behaviors in the context of profiling. This study seeks to develop an empirical model of serial arsonist behaviors that can be systematically associated with probable offender characteristics. Analysis has produced a model of offence behaviors that identify four discrete behavior patterns, all of which share a constellation of common nondiscriminatory behaviors. The inherent behavioral themes of each of these patterns are explored with discussion of their broader implications for our understanding of serial arson and directions for future research.

    This paper describes a CMOS serial link allowing fully duplexed 500 Mbaud serial data communication. The CMOS serial link is a robust and low-cost solution to high data rate requirements. A central charge pump PLL for generating multiphase clocks for oversampling is shared by several serial link channels. Fully duplexed serial data communication is realized in the bidirectional bridge by separating incoming data from the mixed signal on the cable end. The digital PLL accomplishes process-independent data recovery by using a low-ratio oversampling, a majority voting, and a parallel data recovery scheme. Mostly, digital approach could extend its bandwidth further with scaled CMOS technology. A single channel serial link and a charge pump PLL are integrated in a test chip using 1.2 micron CMOS process technology. The test chip confirms upto 500 Mbaud unidirectional mode operation and 320 Mbaud fully duplexed mode operation with pseudo random data patterns.

    Full Text Available This essay presents the discovery of the American serialization of Joseph Conrad’s Lord Jim in New York’s Evening Telegram in 1903. This ‘lost’ serialization, it argues, invites a new perspective on Conrad’s early career by foregrounding the role of newspaper serialization and syndication in establishing his literary standing. After surveying the principal differences in the respective reading experiences of the periodical versus the book, it concludes by proposing that the prominence of women among Conrad’s first audiences requires us to reassess the basis for his success in North America and elsewhere.

    To test whether the conventional radiographic technique in determining bone age abnormalities can be replaced by ultrasonography. A total of 54 Caucasian subjects up to 7 years of age with clinically suspected growth problems underwent left hand and wrist radiographic and ultrasonographic bone age estimations with the use of the Greulich-Pyle atlas. The ultrasonographic scans targeted the ossification centers in the radius and ulna distal epiphysis, carpal bones, epiphyses of the first and third metacarpals, and epiphysis of the middle phalanx, as described in previous reports. The degree of agreement between the two sets of data, as well as the accuracy of the ultrasonographic method in detecting radiographically suggested bone age abnormities, was examined. The mean chronological age, radiographic bone age, and ultrasonographic bone age (all in months) were 41.96 ± 22.25, 26.68 ± 14.08, and 26.71 ± 13.50 in 28 boys and 43.62 ± 24.63, 30.12 ± 17.69, and 31.27 ± 18.06 in 26 girls, respectively. According to the Bland-Altman plot there was high agreement between the results of the two methods with only three outliers. The deviations in bone age from the chronological age taken by the two techniques had the same sign in all patients. Supposing radiography to be the method of reference, the sensitivity, specificity, positive predictive value, and negative predictive value of sonography in detecting growth abnormalities were all 100 % in males and 90.9, 100, 100, and 93.8 %, respectively, in females. The conventional radiographic technique for determining bone age abnormalities could be replaced by ultrasonography. (orig.)

    The aim of this study was to evaluate the accuracy of ultrasonographic measurement of the deep portion of diencephalo-telencephalic vesicle (DPTV) in the prediction of delivery date in different size bitches. The effects of litter size and foetal sex ratio on the accuracy were also investigated. For this purpose, the growth curve of DPTV was derived in large size dogs (26-40 kg) and the results of the accuracy of the prediction were compared with those obtained in small (dogs by the application of the equations derived from the growth curve previously described. Ultrasonographic examinations were performed once a week during the second half of pregnancy in seven large size bitches (26-40 kg body weight). A linear regression model was adopted to analyse the relationship between the DPTV mean values and the days remaining to parturition. The results of regression analysis indicated that DPTV measurement in large size dogs is significantly and linearly related to the gestational age. Ultrasonographic measurements of DPTV were also performed during pregnancy in different size bitches with unknown breeding dates. Although the results indicated a similar accuracy of the prediction of the date of parturition in the different sizes of bitches, a higher accuracy was obtained in normal and large litter size compared with small litters. Foetal sex ratio did not affect the accuracy. In conclusion, this study demonstrated that the accuracy of the prediction of parturition day obtained by ultrasonographic evaluation of DPTV growth is reliable when specific formulae for different size dogs are applied. It should be noted that although foetal sex ratio does not affect the accuracy, the prediction could be less accurate when a small litter is present.

    Here we examine the potential of serial Broad Ion Beam (BIB) Ar{sup +} ion polishing as an advanced serial section tomography (SST) technique for destructive 3D material characterisation for collecting data from volumes with lateral dimensions significantly greater than 100 µm and potentially over millimetre sized areas. Further, the associated low level of damage introduced makes BIB milling very well suited to 3D EBSD acquisition with very high indexing rates. Block face serial sectioning data registration schemes usually assume that the data comprises a series of parallel, planar slices. We quantify the variations in slice thickness and parallelity which can arise when using BIB systems comparing Gatan PECS and Ilion BIB systems for large volume serial sectioning and 3D-EBSD data acquisition. As a test case we obtain 3D morphologies and grain orientations for both phases of a WC-11%wt. Co hardmetal. In our case we have carried out the data acquisition through the manual transfer of the sample between SEM and BIB which is a very slow process (1–2 slice per day), however forthcoming automated procedures will markedly speed up the process. We show that irrespective of the sectioning method raw large area 2D-EBSD maps are affected by distortions and artefacts which affect 3D-EBSD such that quantitative analyses and visualisation can give misleading and erroneous results. Addressing and correcting these issues will offer real benefits when large area (millimetre sized) automated serial section BIBS is developed. - Highlights: • In this work we examine how microstructures can be reconstructed in three-dimensions (3D) by serial argon broad ion beam (BIB) milling, enabling much larger volumes (>250×250×100µm{sup 3}) to be acquired than by serial section focused ion beam-scanning electron microscopy (FIB-SEM). • The associated low level of damage introduced makes BIB milling very well suited to 3D-EBSD acquisition with very high indexing rates. • We explore

  18. Analysis of assembly serial number usage in domestic light-water reactors

    International Nuclear Information System (INIS)

    Reich, W.J.; Moore, R.S.

    1991-05-01

    Domestic light-water reactor (LWR) fuel assemblies are identified by a serial number that is placed on each assembly. These serial numbers are used as identifiers throughout the life of the fuel. The uniqueness of assembly serial numbers is important in determining their effectiveness as unambiguous identifiers. The purpose of this study is to determine what serial numbering schemes are used, the effectiveness of these schemes, and to quantify how many duplicate serial numbers occur on domestic LWR fuel assemblies. The serial numbering scheme adopted by the American National Standards Institute (ANSI) ensures uniqueness of assembly serial numbers. The latest numbering scheme adopted by General Electric (GE), was also found to be unique. Analysis of 70,971 fuel assembly serial numbers from permanently discharged fuel identified 11,948 serial number duplicates. Three duplicate serial numbers were found when analysis focused on duplication within the individual fuel inventory at each reactor site, but these were traced back to data entry errors and will be corrected by the Energy Information Administration (EIA). There were also three instances where the serial numbers used to identify assemblies used for hot cell studies differed from the serial numbers reported to the EIA. It is recommended that fuel fabricators and utilities adhere to the ANSI serial numbering scheme to ensure serial number uniqueness. In addition, organizations collecting serial number information, should request that all known serial numbers physically attached or associated with each assembly be reported and identified by the corresponding number scheme. 10 refs., 5 tabs

    Full Text Available The biopsy of live animal testes is an important clinical manipulation to control spermatogenesis and reproductive system pathologies. The aim was to develop a method of boar testes biopsy using a biopsy gun with ultrasound guidance and to investigate the influence of this procedure on the boar testes parenchyma and quality of ejaculate. The biopsy was carried out in six 8-month-old boars. Fourteen days prior to and 21 days after biopsy, the quality of ejaculate was examined (weight of ejaculate; concentration and motility of spermatozoa with a seven-day intervals. Ultrasound images of the testes parenchyma were recorded three times: directly before and 15 minutes after the biopsy, then 21 days after the procedure. The testes biopsies of generally anesthetized boars were performed with the biopsy gun for needle biopsy with a 12cm long, disposable 16-gauge needle 1.8mm in diameter (Vitesse through 1cm skin incision in the depth of 1.2-1.6cm of parenchyma. Fifteen minutes after the biopsy, macroscopic injures of the parenchyma of all the boar testes were not detected in the ultrasound image. Twenty one days after biopsy, the hyperechogenic line 0.1-0.2cm in diameter was seen in the testes parenchyma of six boars in the depth of 1.2-1.6cm. The biopsy of boar testes did not influence the quality of boars ejaculate. The ultrasonographic examination of boar testicles before the biopsy reduced possibilities to traumatize large blood vessels of the testes. A perfect boar testicular biopsy was easy to perform using ultrasonographic examination in the pigsty conditions.

    In the current world of applications that use reconfigurable technology implemented on field programmable gate arrays (FPGAs), there is a need for flexible architectures that can grow as the systems evolve. A project has limited resources and a fixed set of requirements that development efforts are tasked to meet. Designers must develop robust solutions that practically meet the current customer demands and also have the ability to grow for future performance. This paper describes the development of a high speed serial data streaming algorithm that allows for transmission of multiple data channels over a single serial link. The technique has the ability to change to meet new applications developed for future design considerations. This approach uses the Xilinx Serial RapidIO LOGICORE Solution to implement a flexible infrastructure to meet the current project requirements with the ability to adapt future system designs.

  1. Gasoline-powered serial hybrid cars cause lower life cycle carbon emissions than battery cars

    Battery cars powered by grid electricity promise reduced life cycle green house gas (GHG) emissions from the automotive sector. Such scenarios usually point to the much higher emissions from conventional, internal combustion engine cars. However, today's commercially available serial hybrid technology achieves the well known efficiency gains from regenerative breaking, lack of gearbox, and light weighting - even if the electricity is generated onboard, from conventional fuels. Here, we analyze emissions for commercially available, state-of the-art battery cars (e.g. Nissan Leaf) and those of commercially available serial hybrid cars (e.g., GM Volt, at same size and performance). Crucially, we find that serial hybrid cars driven on (fossil) gasoline cause fewer life cycle GHG emissions (126g CO2e per km) than battery cars driven on current US grid electricity (142g CO2e per km). We attribute this novel finding to the significant incremental life cycle emissions from battery cars from losses during grid transmission, battery dis-/charging, and larger batteries. We discuss crucial implications for strategic policy decisions towards a low carbon automotive sector as well as relative land intensity when powering cars by biofuel vs. bioelectricity.

    This study was conducted to establish representative curves that allow evaluation of fetal growth and estimation of gestational age from measurement of fetal structures by ultrasound in Malayan tapirs (Tapirus indicus). Three pregnancies (i.e. 3 fetuses) were examined in one female Malayan tapir. Transabdominal ultrasonographic examination was performed without anesthesia from 79 ± 8 days to 281 ± 48 days (mean ± S.D.) post mating. To assess fetal growth attempts were made to measure biparietal diameter (BPD), head length (HL), thorax diameter A (TDA), thorax height A (THA), thorax diameter B (TDB), thorax height B (THB), abdomen diameter (AD), abdomen height (AH), humerus length (HUL) and Crown rump length (CRL). The value of each parameter as an estimator of gestational age was assessed by ease of observation and the length of time the parameter was measurable throughout gestation. The most precise predictors for gestational age in this study were BPD and CRL (weeks 10-20 of gestation), as well as AD and AH (weeks 14-43 of gestation). The parameters TDB, THB and HUL (weeks 15-41 of gestation) gave almost as good predictions. Fetal viability was assessed by identifying a fetal heartbeat and movement. All pregnancies resulted in normal deliveries and healthy offspring. The ultrasound examination was well tolerated by the female. The gestation lengths (399 ± 3 days) were within reported ranges. The serial transabdominal ultrasound, without the need for anesthesia, was an effective method to evaluate fetal growth, development and well being in a Malayan tapir. © 2014 Wiley Periodicals, Inc.

    Pilar sheath acanthoma is a rare benign follicular hamartoma that presents with a central sinus containing keratinous material and is lined by epithelium. It typically occurs on the face, especially on the upper lip and forehead. In our case, the ultrasound (US) feature of pilar sheath acanthoma revealed a well-defined, oval hypoechoic nodule with hypoechoic capping within the dermis over the medial aspect of the calf. To the best of our knowledge, despite many reports on the clinicopathological aspects of pilar sheath acanthoma, this entity has not been well described in the radiologic literature, and US findings have not been documented.

    Full Text Available As little is known about the ultrasonographic features of hepatic lipidosis (white liver disease in goats, this study was undertaken to evaluate the use of ultrasound for the diagnosis of hepatic lipidosis associated with vitamin B12 (cyanocobalamin deficiency in Egyptian Zaraibi goats. A total of 38 goats (28 with weight loss, diarrhoea and anaemia and 10 clinically healthy were studied. Twenty-one goats were demonstrated to have cobalt and cyanocobalamin deficiency (0.33 ± 0.12 μmol/l and 0.17 ± 0.10 μg/l, respectively. Goats were examined with a real-time ultrasound system using a 5-MHz convex transducer. Ultrasound-guided liver biopsies and blood samples were obtained from each animal at examination. Based on the histopathological findings, diseased goats were classified as having mild (n = 6, moderate (n = 6 or severe lipidosis (n = 9. Ultrasonographic-hepatic changes were recorded in 19 (90.4% out of 21 goats. Severe lipidosis showed diffuse hyper-echogenicity of hepatic parenchyma. However, focal hyper-echoic lesions with various shapes, sizes and positions were visualized in mild and moderate lipidosis. Liver size increased significantly (P < 0.05 in severely affected goats compared with the controls. Histopathologically, macrovacuolations, congestion of hepatic sinusoids and infiltration of the portal area with inflammatory cells and connective tissues were evident in moderate and severely affected cases. There were varying degrees of anaemia, hypoglycemia and hypoproteinemia with significant increases (P < 0.05 of aspartate aminotransferase (AST and alkaline phosphatase (ALP in diseased animals compared with the controls. In conclusion, ultrasound may be a useful diagnostic tool in goats with suspected hepatic lipidosis associated with vitamin B12 deficiency.

  5. Reconstructing genealogies of serial samples under the assumption of a molecular clock using serial-sample UPGMA.

    Reconstruction of evolutionary relationships from noncontemporaneous molecular samples provides a new challenge for phylogenetic reconstruction methods. With recent biotechnological advances there has been an increase in molecular sequencing throughput, and the potential to obtain serial samples of sequences from populations, including rapidly evolving pathogens, is fast being realized. A new method called the serial-sample unweighted pair grouping method with arithmetic means (sUPGMA) is presented that reconstructs a genealogy or phylogeny of sequences sampled serially in time using a matrix of pairwise distances. The resulting tree depicts the terminal lineages of each sample ending at a different level consistent with the sample's temporal order. Since sUPGMA is a variant of UPGMA, it will perform best when sequences have evolved at a constant rate (i.e., according to a molecular clock). On simulated data, this new method performs better than standard cluster analysis under a variety of longitudinal sampling strategies. Serial-sample UPGMA is particularly useful for analysis of longitudinal samples of viruses and bacteria, as well as ancient DNA samples, with the minimal requirement that samples of sequences be ordered in time.

    The violent murder of Shirley Ellis on November 29, 1987, marked the beginning of the strange and terrible tale of Steven Bryan Pennell's reign as the state of Delaware's first convicted serial killer. Three more bodies followed the first victim, and all had been brutally beaten and sadistically tortured. The body of a fifth woman has never been found. State and county police collaborated with the FBI to identify and hunt down their suspect, forming a task force of over 100 officers and spending about one million dollars. Through their knowledge and experience with other serial killers, the FBI was able to make an amazingly accurate psychological profile of Delaware's serial killer. After months of around-the-clock surveillance, Steven Pennell was arrested on November 29, 1988, one year to the day after the first victim was found. Pennell was found guilty in the deaths of the first two victims on November 29, 1989, and plead no contest to the murder of two others on October 30, 1991. Still maintaining his innocence, he asked for the death penalty so that he could spare his family further agony. Steven Pennell was executed by lethal injection on March 15, 1992.

    Serial sexual murderers have been described as committing homicides in a methodical manner, taking substantial time between offenses to elude the authorities. The results of our study of the temporal patterns (i.e., the length of time between homicides) of a nonrandom national sample of 44 serial sexual murderers and their 201 victims indicate that this representation may not always be accurate. Although 25 offenders (56.8%) killed with longer than a 14-day period between homicides, a sizeable subgroup was identified: 19 offenders (43.2%) who committed homicides in rapid-sequence fashion, with fewer than 14 days between all or some of the murders. Six offenders (13.6%) killed all their victims in one rapid-sequence, spree-like episode, with homicides just days apart or sometimes two murders in the same day. Thirteen offenders (29.5%) killed in one or two rapid-sequence clusters (i.e., more than one murder within a 14-day period, as well as additional homicides with greater than 14 days between each). The purpose of our study was to describe this subgroup of rapid-sequence offenders who have not been identified until now. These findings argue for accelerated forensic assessments of dangerousness and public safety when a sexual murder is detected. Psychiatric disorders with rapidly occurring symptom patterns, or even atypical mania or mood dysregulation, may serve as exemplars for understanding this extraordinary group of offenders. © 2017 American Academy of Psychiatry and the Law.

    Objective: To investigate the relationship between the ultrasonographic changes of gallbladder wall and the hepatic inflammation grading as well as fibrostic staging using ultrasound examination in patients with chronic viral hepatitis, and to survey the diagnostic standard for viral related cholecystitis. Methods: Five hundreds and nineteen chronic viral hepatitis patients and 104 normal control subjects were enrolled in the study. Ultrasound guided liver biopsy was performed in all patients with chronic viral hepatitis, in which the hepatic fibrostic stages(S) were divided into SI (n=148), S2(n=170), S3-4(n 201 ); and hepatic inflammation grades (G) were divided into G1 (n=124 ), G2 (n=204), G3 (n=191). The ultrasound scan was performed within 7 days after liver biopsy. The relationship between ultrasonographic changes of gallbladder and the hepatic inflammation grades and fibrostic stages were analyzed using statistic soft ware SPSS 11.5 for windows. Results: The percentage of the thickened gallbladder wall were 55%, 87%, 96% in S1, S2, S3-4, respectively, and were 45%, 82%, 95% in G1, G2, G3-4, respectively. Significant difference was revealed between G1 and G2, as well as between G2 and G3-4, with P < 0.05. Conclusion: A significant, positive correlative relationship exists between the ultrasonographic changes of gall-bladder wall and the hepatic inflammation grading and fibrostic staging in patients with chronic viral hepatitis.

    The objective of the investigations was to comparatively evaluate the size and shape of the liver on the basis of x-ray and ultrasonographic examinations and to estimate the liver parenchyma and intrahepatic vessels on the basis of ultrasonographic examinations. The studies were done on 64 dogs and 13 cats of different breed and sex, aged from 1 day to 18 years. The ultrasonographic examinations were done with the use of Bruel and Kjaer apparatus type 1849 and Concept 2000 by Dynamic Imaging. In 64 animals the ultrasonographic image of the liver was normal. In 7 cases an enlargement of the liver without any changes in the liver parenchyma was noted. An enlargement of intrahepatic veins was found in 8 cases (4 with circulatory insufficiency, 2 with ascites). The assessment of the size and shape of the liver done on that basis of ultrasound examinations agreed with that based on x-ray examinations. The ultrasonic examinations also allowed the evaluation of the liver parenchyma and intrahepatic veins. (author). 9 refs, figs, 3 tabs.

    Full Text Available The reconstruction of a death scene provides an overall picture of the crime and will indicate the murder as an event or one of a series of events and also the criminal. But when the criminal is declared a serial killer, many questions are raised up. How could a person kill some else without a reason or why people react in such a disorganized way and become so brutal or what made them act like that and so many questions with also so many answers. This project explains the psychology of a murderer, his own way of thinking and acting by presuming that we may accurately discover what is in their minds when they kill. It is about a very complex issue regarding murder investigations, biological factors and psychological profile of a serial killer. Dealing with this problem we will at last reach to the question that could solve finally the puzzle: ―Are serial murderers distorted reflections of society's own values?

    Full Text Available OBJETIVO: Apresentar os aspectos ultra-sonográficos da esclerodermia localizada e relacioná-los com os aspectos clínicos. MATERIAIS E MÉTODOS: Foram analisadas 23 lesões de esclerodermia localizada em 21 pacientes. Foi utilizado equipamento Logiq 700 com transdutor linear de 6-14 MHz. Foram avaliados, pelo dermatologista, o estágio da doença (inflamatório ou atrófico, e pelo radiologista, a espessura e a ecogenicidade da derme nas regiões afetadas e sãs adjacentes. Foi feito acompanhamento de sete casos após tratamento. RESULTADOS: Todas as lesões apresentaram perda do padrão ultra-sonográfico normal da derme. Os casos de lesão clinicamente atrófica (52,2%; 12/23 corresponderam a redução da espessura e aumento da ecogenicidade da derme e os casos de lesão clinicamente inflamatória (47,8%; 11/23 corresponderam a aumento da espessura e redução da ecogenicidade da derme. Controles pós-tratamento mostraram alterações na espessura da derme. CONCLUSÃO: Os achados ultra-sonográficos nos permitem associar o aumento da espessura e a redução da ecogenicidade da derme com a fase inflamatória da doença, e a redução da espessura e o aumento da ecogenicidade da derme com a fase atrófica da doença. Notamos também que é possível quantificar a espessura da derme e usar essa informação no controle pós-tratamento associada à avaliação clínica.OBJECTIVE: To describe ultrasonographic findings of localized cutaneous scleroderma and correlating them with clinical findings.

    The Associative Memory (AM) system of the FTK processor has been designed to perform pattern matching using the hit information of the ATLAS silicon tracker. The AM is the heart of the FTK and it finds track candidates at low resolution that are seeds for a full resolution track fitting. To solve the very challenging data traffic problem inside the FTK, multiple designs and tests have been performed. The currently proposed solution is named the “Serial Link Processor” and is based on an extremely powerful network of 2 Gb/s serial links. This paper reports on the design of the Serial Link Processor consisting of the AM chip, an ASIC designed and optimized to perform pattern matching, and two types of boards, the Local Associative Memory Board (LAMB), a mezzanine where the AM chips are mounted, and the Associative Memory Board (AMB), a 9U VME board which holds and exercises four LAMBs. We report also on the performance of a first prototype based on the use of a min@sic AM chip, a small but complete version ...

    In the absence of vision, perception of space is likely to be highly dependent on memory. As previously stated, the blind tend to code spatial information in the form of "route-like" sequential representations [1-3]. Thus, serial memory, indicating the order in which items are encountered, may be especially important for the blind to generate a mental picture of the world. In accordance, we find that the congenitally blind are remarkably superior to sighted peers in serial memory tasks. Specifically, subjects heard a list of 20 words and were instructed to recall the words according to their original order in the list. The blind recalled more words than the sighted (indicating better item memory), but their greatest advantage was in recalling longer word sequences (according to their original order). We further show that the serial memory superiority of the blind is not merely a result of their advantage in item recall per se (as we additionally confirm via a separate recognition memory task). These results suggest the refinement of a specific cognitive ability to compensate for blindness in humans.

    It has been suggested that people with autism spectrum disorder (ASD) have an increased tendency to use explicit (or intentional) learning strategies. This altered learning may play a role in the development of the social communication difficulties characterizing ASD. In the current study, we investigated incidental and intentional sequence learning using a Serial Reaction Time (SRT) task in an adult ASD population. Response times and event related potentials (ERP) components (N2b and P3) were assessed as indicators of learning and knowledge. Findings showed that behaviorally, sequence learning and ensuing explicit knowledge were similar in ASD and typically developing (TD) controls. However, ERP findings showed that learning in the TD group was characterized by an enhanced N2b, while learning in the ASD group was characterized by an enhanced P3. These findings suggest that learning in the TD group might be more incidental in nature, whereas learning in the ASD group is more intentional or effortful. Increased intentional learning might serve as a strategy for individuals with ASD to control an overwhelming environment. Although this led to similar behavioral performances on the SRT task, it is very plausible that this intentional learning has adverse effects in more complex social situations, and hence contributes to the social impairments found in ASD.

    OBJECTIVE To assess the effects of age, body condition score (BCS), and muscle condition score (MCS) on radial and coccygeal systolic arterial blood pressure (SAP) in cats. DESIGN Prospective randomized trial. ANIMALS 66 privately owned cats enrolled between May and December 2010. PROCEDURES BCS and MCS of cats were assessed by 2 investigators; SAP was measured via Doppler ultrasonic flow detector, with cats positioned in right lateral or sternal recumbency for measurements at the radial or coccygeal artery, respectively, with order of site randomized. Associations among variables were assessed through correlation coefficients, partial correlation coefficients, and ANCOVA. RESULTS Interrater reliability for BCS and MCS assessment was high (correlation coefficients, 0.95 and 0.83, respectively). No significant effect was identified for order of SAP measurement sites. Coccygeal and radial SAP were positively correlated (ρ = 0.45). The median difference in coccygeal versus radial SAP was 19 mm Hg, but differences were not consistently positive or negative. Radial SAP was positively correlated with age (ρ = 0.48) and negatively correlated with MCS (ρ = -0.30). On the basis of the correlation analysis, the association between radial SAP and MCS reflected the confounding influence of age. Coccygeal SAP was not significantly correlated with age, BCS, or MCS. CONCLUSIONS AND CLINICAL RELEVANCE Use of the coccygeal artery is recommended to reduce the confounding effects of age and sarcopenia on Doppler ultrasonographic SAP measurements in cats. Additionally, monitoring for changes in MCS is recommended for cats undergoing serial SAP measurement.

    The imaging findings of complex fibroadenoma have been rarely reported even though the risk of developing breast carcinoma in a patient with complex fibroadenoma is higher than that for a patient with simple fibroadenoma. We reviewed the imaging features and pathologic findings of complex fibroadenomas. Between April 2003 and April 2010, the mammographic and sonographic findings of five patients with complex fibroadenomas were retrospectively reviewed according to the Breast Imaging Reporting and Data System (BIRADS). The pathologic findings were retrospectively reviewed for all 5 patients. The mammography findings showed masses (3 cases) and asymmetry (1 case). On ultrasonography, complex echo patterns were noted in all the patients, and all the lesions were assigned to BI-RADS category 4, suspicious for abnormality. The complex echoic patterns showed two types: 1) a mixture of a heterogeneous hypoechoic central portion and a fuzzy hyperechoic peripheral area in 2 cases, 2) a mixture of tiny anechoic and hypoehoic lesions in 3 cases. Multiple cystic changes were noted in all the cases on the pathologic analysis. Complex fibroadenomas showed different ultrasonographic findings from simple fibroadenomas such as two types of complex echo patterns, even though the other findings were similar to those of simple fibroadenoma. Cystic changes were noted in all the cases on the pathologic analysis. Awareness of these imaging findings will help us to properly diagnose complex fibroadenoma

    Sequential ultrasonography was performed in 22 cases of intrahepatic hematomas diagnosed by operation, laboratory data, and clinical manifestation. We analyzed the shape, location, size of hematoma, and change in size and echogenicity by age of hematoma. The results were as follows: 1. The most common shape of intrahepatic hematoma was round. 2. The most common site of intrahepatic hematoma was the posterior segment of the right lobe of the liver. 3. Size of hematoma was decreased from 3rd day, and most hematomas were nearly or completely absorbed from 2nd week to 4th week. 4. Echogenecities of intrahepatic hematoma in immediate ultrasonography after injury showed mainly echogenic or mixed form, and then the echogenecities were decreased and nearly or completely not seen from 2nd week to 4th week

    To assess the role of ultrasonographic measurement of the upper and lower uterine segments wall thickness in predicting the progress of preterm labour in patients presenting with preterm labour pains. Fifty pregnant women presenting at Obstetrics Department - Suez Canal University, Egypt with regular lower abdominal pains and diagnosed as having preterm labour were enrolled in the study. Measurements of the upper and lower uterine segments wall thickness by transabdominal ultrasonography in-between contractions and with full bladder were taken. The upper/lower uterine wall thickness ratio was calculated and correlated to the progress of the preterm labour and to the response to tocolytics. The ultrasonographic upper/lower uterine wall thickness ratio was directly related to the progress of preterm delivery (PTD). The change in this ratio is correlated inversely with the response to tocolysis. Using the ROC curve, when the upper/lower uterine wall thickness ratio was ≤ 1.26 the sensitivity was 94.74 and the specificity was 100.00, and when the ratio was ≤ 1.52 the sensitivity was 100.00 and the specificity was 83.33. These data may serve as a baseline ultrasonographic reference values for further studies in prediction the progress of preterm labour in patients presenting with preterm labour pains.

    Although serial murder has been recorded for centuries, limited academic attention has been given to this important topic. Scholars have attempted to examine the causality and motivations behind the rare phenomenon of serial murder. However, scant research exists which delves into the childhood characteristics of serial murderers. Using social learning theory, some of these studies present supporting evidence for a link between childhood animal cruelty and adult aggression toward humans. Based on five case studies of serial murderers, we contribute to the existing literature by exploring the possible link between childhood cruelty toward animals and serial murder with the application of the graduation hypothesis.

    To describe ultrasound findings of Kimura's disease arising in the upper extremities. Five patients with Kimura's disease confirmed by surgical resection were retrospectively reviewed by two musculoskeletal radiologists and a pathologist. All six lesions involved the epitrochlear area and appeared as partially (n = 5) or poorly (n = 1) marginated subcutaneous masses with the presence of curvilinear hyperechoic bands intermingled within the hypoechoic components by US. Moderate (n = 4) to severe (n = 2) vascular signals were observed in some proportion of the hyperechoic bands by color Doppler US. The associated findings were the increased echogenicity of surrounding subcutaneous fat (n = 6) and adjacent lymphadenopathy (n = 4). Microscopic examination showed proliferation of lymphoid follicles with prominent germinal centers and intervening fibrosis. In this study, Kimura's disease arising in the upper extremities showed a partially defined hypoechoic subcutaneous mass with internal hyperechoic bands and moderate-to-severe vascularities, increased echogenicity of the surrounding subcutaneous fat and adjacent lymphadenopathy on US. Thus, when these US features are observed in the typical epitrochlear region of an Asian individual, especially if accompanied by peripheral eosinophilia, Kimura's disease should be considered as a possible diagnosis.

  10. Serial Austen. Mashingups with Zombies

    Full Text Available Jane Austen sells. She sells in all possible ways, her novels have been adapted for the cinema and the stage, they have been rewritten as comics and graphic novels. Jane austen is a cultural icon. The interest in her life is so strong that many biographies have been written in order to recover new facts and details. The places where she has lived and the places depicted in her novels have become tourist sites for literary pilgrims. Austen is a cross-over phenomenon, with regency costume balls recreated in her name and an endless proliferation of her works in all media. My essay will investigate Jane Austen and Seth Grahame-Smith’s Pride and Prejudice and Zombies (2009, a mash-up novel which has become a real cultural phenomenon of the last decade and will demonstrate how it can be considered a serial narrative. If as Henry Jenkins asserts, seriality implies the unfolding of a story over time through a process of “chunking” (that is creating meaningful parts of the same story and of “dispersal” (that is breaking the story into more parts and in more genres and media, mash-ups seems to do this.  Austen’s story remains as a “story hook” which pushes the reader to come back to different products for a continuation of the same story. So, if on the one hand, seriality occurs within the same text, the story-telling of Austen’s stories across genres and media is part of a seriality process.

    Ultrasonographic images were acquired of the mammary glands of 40 bitches with physiologically lactating (n = 20) or inflamed glands (n = 20). Echogenicity, structure, homogeneity, thickness, and distinguishability of each tissue layer were assessed. Additionally, overall echogenicity was noted. In the normal lactating gland, different tissues could be differentiated easily. The parenchyma was, without exception, separated from adjacent tissues and was visible as medium echogenic tissue with a coarse-grained structure. The tissue always had some echogenic lines and anechoic areas and was slightly heterogeneous. The loss of distinct layering of the tissue was characteristic of an inflamed mammary gland and inflamed regions had reduced echogenicity. Additionally in five bitches with mastitis, the ultrasound examination was repeated five times for documentation of the progress of the illness and associated changes, supplemented with a color Doppler sonogram to assess changes in blood vessel density. Information from the examinations carried out via B-mode did not allow treatment success to be predicted. Two bitches with reduced blood vessel density centrally had a poor outcome whereas three bitches with increased blood vessel density had a good outcome. Thus, Doppler sonography might be a useful tool to obtain information of the prognosis in acute canine mastitis.

    Serial murders attract attention from the media, mental health experts, academia, and the general public. We present a case of serial murders that took place in a limited area and which caused public anxiety and anguish in central India. All the victims were homeless beggars, who were bludgeoned to death (crush injury). Individual murders were initially investigated by different police stations; fortunately, since they sent all the bodies to a common autopsy centre, a forensic pathologist was able to link all the cases, the first person to do so. This emphasises the need for sharing information among police stations and autopsy centres.

  15. Ultrasonographic Assessment of Diaphragm Function in Critically Ill Subjects.

    2016-04-01

    The majority of patients admitted to the ICU require mechanical ventilation as a part of their process of care. However, mechanical ventilation itself or the underlying disease can lead to dysfunction of the diaphragm, a condition that may contribute to the failure of weaning from mechanical ventilation. However, extended time on the ventilator increases health-care costs and greatly increases patient morbidity and mortality. Nevertheless, symptoms and signs of muscle disease in a bedridden (or bed rest-only) ICU patient are often difficult to assess because of concomitant confounding factors. Conventional assessment of diaphragm function lacks specific, noninvasive, time-saving, and easily performed bedside tools or requires patient cooperation. Recently, the use of ultrasound has raised great interest as a simple, noninvasive method of quantification of diaphragm contractile activity. In this review, we discuss the physiology and the relevant pathophysiology of diaphragm function, and we summarize the recent findings concerning the evaluation of its (dys)function in critically ill patients, with a special focus on the role of ultrasounds. We describe how to assess diaphragm excursion and diaphragm thickening during breathing and the meaning of these measurements under spontaneous or mechanical ventilation as well as the reference values in health and disease. The spread of ultrasonographic assessment of diaphragm function may possibly result in timely identification of patients with diaphragm dysfunction and to a potential improvement in the assessment of recovery from diaphragm weakness.

    Two patients with serologically confirmed herpes simplex encephalitis were studied by serial CT scannings. Case 1, a 60-year-old woman, was admitted to National Cardiovascular Center because of headache, fever, and attacks of Jacksonian seizure. Case 2, a 54-year-old man, was admitted because of fever, consciousness disturbance and right hemipare sis. Pleocytosis (mainly lymphocytes) and elevation of protein content in cerebrospinal fluid were observed in both cases. Both patients presented ''das apallische Syndrom'' one month after admission. The diagnosis of herpes simplex encephalitis was confirmed by typical clinical courses and by greater than fourfold rises in serum antibody titer for herpes simplex virus as well as that in cerebrospinal fluid in case 1. Characteristic CT findings observed in these two cases were summarized as follows: Within a week after the onset, no obvious abnormalities could be detected on CT scans (Case 1). Two weeks after the onset, a large low-density area appeared in the left temporal lobe and in the contralateral insular cortex with midline shift toward the right side (Case 2). One month later, an ill-defined linear and ring-like high-density area (Case 1), or a well-defined high-density area (Case 2), that was enhanced after contrast administration, was observed in the large low-density area in the temporal lobe. These findings were considered as characteristic for hemorrhagic encephalitis. These high-density areas disappeared two months later, however, widespread and intensified low-density areas still remained. In both cases, the basal ganglia and thalamus were completely spared on CT scans. From these observations, it can be concluded that serial CT scannings are quite useful for diagnosis of herpes simplex encephalitis. (author)

  17. Child serial murder-psychodynamics: closely watched shadows.

    There is a malignant transformation in object relations resulting in an identification with an omnipotent and cruel object resulting in an identity transformation. If the tension, desperation, and dissociation increase, serial murder becomes spree murder. The presence of pathological narcissism and psychopathic tendencies are of diagnostic significance in understanding the murderer's personality functioning and motivation to kill. Meloy (1988) considered the degree of sadism and aggression combined with narcissistic qualities to reflect the "malignancy" of the psychopathic disturbance where gratification (of aggression) occurs in the service of narcissistic functioning--that is, cruelty toward others in the form of a triumphant victory over a rejecting object. Meloy also believes that dissociation is ubiquitious in the psychopath. The initial murder of the serial murderer may reflect a "new identity." The pathological object-relations of narcissism and the malignant narcissism are important diagnostic indicators in the personality functioning of serial killers and the occurrence of these phenomena is a significant factor in the formation of the personalities of serial killers, their inner motivations, and their pattern of commission.

    2011-01-01

    The current front-end electronics of the ATLAS Liquid Argon calorimeters need to be upgraded to sustain the higher radiation levels and data rates expected at the upgraded LHC machine (HL-LHC), which will have 5 times more luminosity than the LHC in its ultimate configuration. This upgrade calls for an optical link system of 100 Gbps per front-end board (FEB). A high speed, low power, radiation tolerant serializer is the critical component in this system. In this paper, we present the design and test results of a single channel 16:1 serializer and the design of a double-channel 16:1 serializer. Both designs are based on a commercial 0.25 μm silicon-on-sapphire CMOS technology. The single channel serializer consists of a serializing unit, a PLL clock generator and a line driver implemented in current mode logic (CML). The serializing unit multiplexes 16 bit parallel LVDS data into 1-bit width serial CMOS data. The serializing unit is composed of a cascade of 2:1 multiplexing circuits based on static D-flip-fl...

  3. Further evidence that similar principles govern recall from episodic and semantic memory: the Canadian prime ministerial serial position function.

    2011-06-01

    The serial position function, with its characteristic primacy and recency effects, is one of the most ubiquitous findings in episodic memory tasks. In contrast, there are only two demonstrations of such functions in tasks thought to tap semantic memory. Here, we provide a third demonstration, showing that free recall of the prime ministers of Canada also results in a serial position function. Scale Independent Memory, Perception, and Learning (SIMPLE), a local distinctiveness model of memory that was designed to account for serial position effects in episodic memory, fit the data. According to SIMPLE, serial position functions observed in episodic and semantic memory all reflect the relative distinctiveness principle: items will be well remembered to the extent that they are more distinct than competing items at the time of retrieval.

    To retrospectively analyze and compare the ultrasonographic characteristics and BI-RADS-US classification between patients with BRCA1 mutation-associated breast cancer and those without BRCA1 gene mutation in Guangxi, China. The study was performed in 36 lesions from 34 BRCA1 mutation-associated breast cancer patients. A total of 422 lesions from 422 breast cancer patients without BRCA1 mutations served as control group. The comparison of the ultrasonographic features and BI-RADS-US classification between two the groups were reviewed. More complex inner echo was disclosed in BRCA1 mutation-associated breast cancer patients (x(2) = 4.741, P = 0.029). The BI-RADS classification of BRCA1 mutation-associated breast cancer was lower (U = 6094.0, P = 0.022). BRCA1 mutation-associated breast cancer frequently displays as microlobulated margin and complex echo. It also shows more benign characteristics in morphology, and the BI-RADS classification is prone to be underestimated.

    Despite numbers of publications and effort to try to establish the definition, the classification, the epidemiology, the clinical aspects and the psychopathology of serial killers, a universal consensus seems to say the least. Crime, though reduced in some countries, appears to impact more and more consistent worldwide, generating controversial ideas and a multitude of possible explanations. The serial killer usually presents as a caucasian man, aged between 20 and 40 years, often embedded socially and in his family, but with serious psychiatric, personal and especially family history. Usually acting alone, the serial killer plans a crime well in advance, but sometimes within the scope of impulsivity for a minority, the victim not being previously selected. In the latter case, an actual mental illness like psychosis is found. It is clear from numerous psychopathological studies conducted so far that most serial killers are defined as psychopathic sexual sadists, whose childhood was difficult, if not flouted, punctuated by physical and psychological violence situations. In addition, pervasive fantasies combined with thoughts of death, sex and violence are as much in common with the original acts of which they are the instigators. Beyond a relentless media that is constantly watering the public with stories and pictures depicting them as such, serial killers remain an enigma. We can therefore attempt to answer the various questions raised by this phenomenon, the way these people operate and how we can curb the rise, thanks to the neurobiological and neurophysiological approaches that science offers us.

    Full text: Aim of the study: Estimation of the early effects of the treatment of hyperthyroidism with radioactive iodine in correlation with the radioiodine dose, the age at the onset of disease and ultrasonographic (US) findings of the thyroid. Material and methods: Retrospective analysis of the files of 80 patients that underwent a radioactive iodine treatment from the period of 1987 till 2006 because of a diffuse hyperthyroid goiter was performed. The patients were divided in two groups. Group C consisted of patients who were treated with calculated doses from 60-100μC/ml gland volume and group NC who received higher, non-calculated doses. According to age at the onset of disease patients were divided in two groups- group A younger than 40 years and group B older than 40 years. According to the US findings of the thyroid prior to radioiodine therapy patients were divided in two groups group N with predominantly normal US findings and group H with predominantly hypoechoic structure. Results: One year after the application of radioactive iodine 58% of the patients from the group C still remained hyperthyroid, 29% became euthyroid and only 13% developed early hypothyroidism. In the NC group only 7% remained hyperthyroid, 40% were euthyroid, while 54% of the patients developed early hypothyroidism. The occurrence of early hypothyroidism was significantly more frequent in NC than in C group (58% vs. 32%, p<0.05). The age was predictor for the probability of development of early hypothyroidism in C group: only 13% younger in group A, but 46% older patients from group B developed an early hypothyroidism. In the NC group the age was not a predictive factor. In 44 patients there were available records on the US findings prior to radioiodine therapy. In the N group patients that received calculated dose of radioiodine therapy remained euthyroid in 86%, while the patients that received non-calculated dose achieved euthyroidism only in 30%.In the H group there was no

    In order to apply serial magnification angiography to clinical examinations so easily, a serial cardioangiography apparatus was equipped with a tube having 0.1 mm focal spot and with DRX-431HD diode. A CAT-FK Type catheter bed (Toshiba) was used as a roentgenographic table and a PUCK film changer was used. Thus, serial magnification angiography can be easily used to clinical examinations, and can be set in a usual x-ray photographic studio. Serial magnification angiography was used to examine the cerebral vessels in 6 patients, vessels of the pulmonary circulation in 1 patient, bronchial arteries in 6 patients, the celiac artery in 18 patients, the superior mesenteric artery in 2 patients, inferior mesenteric artery in 2 patients, the renal artery in 2 patients, and the adrenal vein in 7 patients. Owing to this angiography, minute changes in the vessel in the lesion can be observed and fine neovascularity can be detected. Thus, serial magnification angiography makes diagnoses of vascular disorders easier. (Ichikawa, K.)

    Purpose: Kikuchi's disease, or histiocytic necrotizing lymphadenitis, is a self-limited necrotizing lymphadenitis. Clinically, it resembles lymphoma. We want to compare the sonographic features between Kikuchi's disease and lymphoma in patients with cervical lymphadenopathy. Materials and methods: The study protocol was approved by the institutional review board. Two hundred and twenty six cervical lymph nodes (137 nodes from 21 Kikuchi's disease patients and 89 nodes from 20 malignant lymphoma patients) were examined. The demographic and ultrasonographic characteristics of lymph nodes were collected and analyzed. Results: The Kikuchi's disease patients (mean age, 24.2 years; range, 8–57 years) were younger than those with lymphoma (mean age, 54 years; range, 13–81 years). There was no difference in laterality of nodes (p = 0.19). The nodal distribution demonstrated most enlarged neck lymph nodes located at level II, III and V. The ranges of short-axis and long-axis length were 6.5 ± 2.3 mm (mean ± SD) versus 13.4 ± 5.1 mm and 13.4 ± 5.0 mm versus 21.2 ± 9.2 mm for Kikuchi's disease versus lymphoma (p 0.05). Conclusion: Analysis of basic ultrasonographic characteristics (size, shape, rims, matting and echotexture) helps differentiate cervical lymph nodes in patients with Kikuchi's disease and lymphoma. Cervical lymphadenopathies in patients with Kikuchi's disease have smaller size, less round, less micronodular reticular echotexture, and more signs of matting and cortical widening than those with lymphoma examined under ultrasound.

    Full Text Available Television studies has produced few sustained analyses of performance in serial television. Yet film studies scholarship has shown how attending to the integration of performances with other aspects of film style is crucial to the interpretation and appreciation of expression and meaning in filmed narrative fictions. However, as a particle form of filmed serial narrative, series television raises a number of questions about performance that will not necessarily be satisfyingly addressed by the direct adoption and application of approaches to writing about performance that have been honed in regard to film. How, then, do we write about performance in television serials in ways that recognise and accommodate the form’s relationship to film, while at the same time appropriately acknowledging and responding to long-form television’s serial status? To examine the difficulties and opportunities of approaching performance in serial television this way, the article conducts close readings of various pieces of television studies writing on performance, by scholars such as Jason Mittell, Sue Turnbull, George Toles, and Steven Peacock. Their work brings into view film and television’s points of common relation, and the distinctive challenges, achievements, and rewards of appreciating the best television serials, and the performances in them.

    Full Text Available Crayon Shin Chan, a Japanese two-dimension animation series broadcast in one of private Indonesian TVs, is categorized into child’s program since it is broadcast at child’s prime time, Sunday 08.30 a.m. In spite of its broadcast time, this series consist of symbols directed not for children, such as some acts that are not appropriate to be done by children, especially in Indonesia. Moreover, adult symbols of sex are also found in the program. For this reason it will be interesting to analyze it using semiotic analysis. Semiotics is the study of symbol and its meaning which its principle concept is that both signifier and signified consist of symbols and are related to denotation and connotation.   Crayon Shin Chan merupakan serial animasi dua dimensi yang tayang di salah satu stasiun televisi swasta di Indonesia. Ini merupakan produk animasi 2 dimensi yang diimpor dari Jepang. Di Indonesia, serial ini masuk dalam kategori acara anak. Hal ini dapat dilihat dari jam penayangannya yang merupakan waktu prime time bagi anak, yakni pada hari minggu pukul 08.30. Akan tetapi, pada serial ini banyak simbol-simbol yang mengarah pada tayangan yang bukan untuk anak-anak, yakni adeganadegan yang tidak pantas dilakukan oleh anak khususnya di Indonesia. Serta adanya pula simbol-simbol yang mengarah pada tayangan berbau dewasa. Tentu akan menarik jika tayangan ini diteliti menggunakan analisis semiotika. Semiotika sendiri merupakan kajian ilmu mengenai tanda dan makna. Yang pada prinsipnya, konsep penting seperti penanda (signifier dan petanda (signified sama-sama terdiri dari tanda dan terkait dengan denotasi dan konotasi.

    A 10-year-old entire female Beagle dog was evaluated for an acute history of lethargy, anorexia, and diarrhea. Mammary tumors were detected during physical examination. Ultrasonographic scanning revealed the presence of a unique pattern of multiple, well-defined and well-marginated hypoechoic nodules in the muscularis layer of the jejunum. These nodules were not associated with changes in the rest of the normal intestinal layering and were not causing signs of intestinal obstruction. Mammary carcinoma metastases to the intestinal muscularis layer were diagnosed based on histopathological examination. © 2013 American College of Veterinary Radiology.

  15. Stochastic modeling of a serial killer.

    Simkin, M V; Roychowdhury, V P

    2014-08-21

    We analyze the time pattern of the activity of a serial killer, who during 12 years had murdered 53 people. The plot of the cumulative number of murders as a function of time is of "Devil's staircase" type. The distribution of the intervals between murders (step length) follows a power law with the exponent of 1.4. We propose a model according to which the serial killer commits murders when neuronal excitation in his brain exceeds certain threshold. We model this neural activity as a branching process, which in turn is approximated by a random walk. As the distribution of the random walk return times is a power law with the exponent 1.5, the distribution of the inter-murder intervals is thus explained. We illustrate analytical results by numerical simulation. Time pattern activity data from two other serial killers further substantiate our analysis. Copyright © 2014 Elsevier Ltd.

    The purpose of this study is to test the possibility of obtained cell-like resolution in soft tissue tumors on the basis of ultrasound echotexture. This is a prospective study consisting of 57 patients (29 females and 28 males, age range: 9-83 years, average age: 44.5 years) with palpable soft tissue mass, referred from the Departments of Orthopedics and Oncology for ultrasound (US)-guided biopsy. The study was approved by the institutional review board (IRB) of our hospital. Ultrasonographic images were recorded by still imaging in the biopsy tract in each biopsy session. Equipment included curvilinear and linear array probes. After biopsy, a radiologist and a pathologist correlated the US image and the observations regarding the histology of the tissue specimen in low-power (40 × magnification) and high-power (100-400 × magnification) fields. The histologic results included 22 benign and 35 malignant lesions. The echotexture of the soft tissue tumors correlated well with the cellular distribution and arrangement: the greater the number of cells and the more regular their arrangement as seen histologically, the greater is the hypoechogenicity on the ultrasound. The echogenicity of the soft tissue tumor also correlated well with the presence of fat cells, hemorrhage, cartilage, and osteoid tissue, all of which cause an increase in echogenicity. This study showed that the echotexture of soft tissue tumors can predict some details of cellular histology. Copyright © 2017. Published by Elsevier Taiwan LLC.

    We have experimentally studied the diffusion thermopower of a serial double quantum dot, defined electrostatically in a GaAs/AlGaAs heterostructure. We present the thermopower stability diagram for a temperature difference ΔT = (20 ± 10) mK across the device and find a maximum thermovoltage signal of several μV in the vicinity of the triple points. Along a constant energy axis in this regime, the data show a characteristic pattern which is in agreement with Mott's relation and can be well understood within a model of sequential transport.

  20. The predictive diagnostic value of serial daily bedside ultrasonography for severe dengue in Indonesian adults.

    Directory of Open Access Journals (Sweden)

    Meta Michels

    Full Text Available BACKGROUND: Identification of dengue patients at risk for progressing to severe disease is difficult. Significant plasma leakage is a hallmark of severe dengue infection which can suddenly lead to hypovolemic shock around the time of defervescence. We hypothesized that the detection of subclinical plasma leakage may identify those at risk for severe dengue. The aim of the study was to determine the predictive diagnostic value of serial ultrasonography for severe dengue. METHODOLOGY/PRINCIPAL FINDINGS: Daily bedside ultrasounds were performed with a handheld ultrasound device in a prospective cohort of adult Indonesians with dengue. Timing, localization and relation to dengue severity of the ultrasonography findings were determined, as well as the relation with serial hematocrit and albumin values. The severity of dengue was retrospectively determined by WHO 2009 criteria. A total of 66 patients with proven dengue infection were included in the study of whom 11 developed severe dengue. Presence of subclinical plasma leakage at enrollment had a positive predictive value of 35% and a negative predictive value of 90% for severe dengue. At enrollment, 55% of severe dengue cases already had subclinical plasma leakage, which increased to 91% during the subsequent days. Gallbladder wall edema was more pronounced in severe than in non-severe dengue patients and often preceded ascites/pleural effusion. Serial hematocrit and albumin measurements failed to identify plasma leakage and patients at risk for severe dengue. CONCLUSIONS/SIGNIFICANCE: Serial ultrasonography, in contrast to existing markers such as hematocrit, may better identify patients at risk for development of severe dengue. Patients with evidence of subclinical plasma leakage and/or an edematous gallbladder wall by ultrasonography merit intensive monitoring for development of complications.

    A system includes a controller and a serial robot having links that are interconnected by a joint, wherein the robot can grasp a three-dimensional (3D) object in response to a commanded grasp pose. The controller receives input information, including the commanded grasp pose, a first set of information describing the kinematics of the robot, and a second set of information describing the position of the object to be grasped. The controller also calculates, in a two-dimensional (2D) plane, a set of contact points between the serial robot and a surface of the 3D object needed for the serial robot to achieve the commanded grasp pose. A required joint angle is then calculated in the 2D plane between the pair of links using the set of contact points. A control action is then executed with respect to the motion of the serial robot using the required joint angle.

    The representation of serial killers was examined from the analysis of 317 Web pages in the Italian language to study how the psychological profiles of serial killers are described on the Italian Internet. The correspondence analysis of the content of these Web pages shows that in Italy the serial killer is associated with words such as "monster" and "horror," which suggest and imply psychological perversion and aberrant acts. These traits are peculiar for the Italian scenario.

    Inflammatory pseudotumor, also known as inflammatory myofibroblastic tumor and plasma cell granuloma, is an uncommon low-grade lesion composed of spindle cells admixed with mature plasma cells and other inflammatory cells, such as histiocytes, lymphocytes, and eosinophils. Here, we describe the mammographic and ultrasonographic findings of a case of an inflammatory pseudotumor of the breast in a 60-year-old woman. With the suspicion of malignancy, core needle biopsy and surgical excision confirmed the mass as being an inflammatory pseudotumor of the breast.

    To evaluate changes of the high-resolution (HR) gray scale and doppler ultrasonographic (US) characteristics of experimentally induced acute uric acid (UA) nephropathy in rabbits. Acute UA nephropathy was induced in ten rabbits using supersaturated lithium carbonate solution. The rabbits were divided in two groups. Group I consisted of five rabbits, and they were injected with a single dose of 150 ml of saturated UA over one hour. During tis period, serial US studies of the kidneys of these rabbits were performed every ten minutes. Group II consisted of the remaining five rabbits, and three injections of 50 ml of saturated UA solution were given on the first, fifth and eight day and follow-up was done upto twenty fifth day. Sequential HR and Doppler US, renal biopsy and blood sampling were performed on day 1, 5, 8, 21, and 25 in the group II rabbits. In group I, HR and Doppler US examination revealed the normal resistive index without significant abnormality. On the other hand, US studies of group II showed poor renal corticomedullary differentiation, decreased renal blood flow and elevated resistive index. There was statistically significant correlation among US findings, histologic characteristics and chemical index (BUN, creatinine) of renal function. In addition, sequentially increased size and volume of the kidney were noted in both groups. HR gray scale and doppler US characteristics of experimentally induced acute UA nephropathy in rabbits were similar to those of acute renal failure caused by other well-known causes.

    Two patients with serologically confirmed herpes simplex encephalitis were studied by serial CT scannings. Case 1, a 60-year-old woman, was admitted to National Cardiovascular Center because of headache, fever, and attacks of Jacksonian seizure. Case 2, a 54-year-old man, was admitted because of fever, consciousness disturbance and right hemiparesis. Pleocytosis (mainly lymphocytes) and elevation of protein content in cerebrospinal fluid were observed in both cases. Both patients presented ''das apallische Syndrom'' one month after admission. The diagnosis of herpes simplex encephalitis was confirmed by typical clinical courses and by greater than fourfold rises in serum antibody titer for herpes simplex virus as well as that in cerebrospinal fluid in case 1. Characteristic CT findings observed in these two cases were summarized as follows: Within a week after the onset, no obvious abnormalities could be detected on CT scans (Case 1). Two weeks after the onset, a large low-density area appeared in the left temporal lobe and in the contralateral insular cortex with midline shift toward the right side (Case 2). One month later, an ill-defined linear and ring-like high-density area (Case 1), or a well-defined high-density area (Case 2), that was enhanced after contrast administration, was observed in the large low-density area in the temporal lobe. These findings were considered as characteristic for hemorrhagic encephalitis. These high-density areas disappeared two months later, however, widespread and intensified low-density areas still remained. In both cases, the basal ganglia and thalamus were completely spared on CT scans. From these observations, it can be concluded that serial CT scannings are quite useful for diagnosis of herpes simplex encephalitis.

    2002-01-01

    The Serial Micro Channel SMC 2100 offers an ''intelligent stand alone'' electronics for the radiation measuring technique's. First it is designed of being connected to a serial interface RS232 of a PC. With a RS485 serial interface on a PC, a network structure can be generated. It has all functional modules which are necessary for the measurement of detector signals. Hence it is possible to directly connect any detector for radiation measurement to a PC, laptop, or notebook. All variations can be operated without PC support too. It has a modular structure and consists of two blocks, the functional modules and the basic modules. The Serial Micro Channel SMC 2100 may be directly coupled to a detector, which therefore makes the realisation of an ''intelligent radiation detector'' with serial link RS232 or RS485. (orig.)

  11. Examining the relationship between free recall and immediate serial recall: the serial nature of recall and the effect of test expectancy.

    Bhatarah, Parveen; Ward, Geoff; Tan, Lydia

    2008-01-01

    In two experiments, we examined the relationship between free recall and immediate serial recall (ISR), using a within-subjects (Experiment 1) and a between-subjects (Experiment 2) design. In both experiments, participants read aloud lists of eight words and were precued or postcued to respond using free recall or ISR. The serial position curves were U-shaped for free recall and showed extended primacy effects with little or no recency for ISR, and there was little or no difference between recall for the precued and the postcued conditions. Critically, analyses of the output order showed that although the participants started their recall from different list positions in the two tasks, the degree to which subsequent recall was serial in a forward order was strikingly similar. We argue that recalling in a serial forward order is a general characteristic of memory and that performance on ISR and free recall is underpinned by common memory mechanisms.

    1980-01-01

    Here, a new time averaging circuit design, the 'parallel filter' is presented, which can reduce the time jitter, introduced in time measurements using counters of large dimensions. This parallel filter could be considered as a single stage unit circuit which can be repeated an arbitrary number of times in series, thus providing a parallel-serial filter type as a result. The main advantages of such a filter over a serial one are much less electronic gate jitter and time delay for the same amount of total time uncertainty reduction. (orig.)

    2011-06-01

    Serial forced displacement has been defined as the repetitive, coercive upheaval of groups. In this essay, we examine the history of serial forced displacement in American cities due to federal, state, and local government policies. We propose that serial forced displacement sets up a dynamic process that includes an increase in interpersonal and structural violence, an inability to react in a timely fashion to patterns of threat or opportunity, and a cycle of fragmentation as a result of the first two. We present the history of the policies as they affected one urban neighborhood, Pittsburgh's Hill District. We conclude by examining ways in which this problematic process might be addressed.

    To evaluate the accuracy and ultrasonographic findings of primary and secondary hyperparathyroidism (HPT) and correlate them with pathologic results. We reviewed 31 cases of surgically confirmed primary (n=22) and secondary (n=9) hyperparathyroidism. We used 10 or 7.5 MHz linear transducer and reviewed the location, contour, size and echogenicity of lesions. Then we evaluated the detection rate of parathyroid lesions based on surgical result and compared the result of 99m Tc-sestamibi scan (15 cases). Location of primary HPT was left lower in 9, left upper in 5, right lower in 4, right upper in 3, left midportion in 1 and superior mediastinum in 1. Lesions showed variable echogenicity-mild low echo (2), moderate low echo (10), severe low echo (2), isoecho (4) and heterogeneous echo pattern (1). All the lesions except 5 were well defined and 3 lesions had echogenic rim. Posterior enhancement and lateral shadowing were noted in 3 and 4 lesions, respectively. Nineteen of 23 primary lesions were detected by ultrasonography (82.6%) and well correlated with sestamibi scan. In case of secondary HPT, most were well defined low echoic nodular lesions, and we could detect 6 of 9 patients (67%) and 15 of 36 lesions (41.7%). Only 6 of 24 secondary lesion were detected by sestamibi scan (25%). The detection rate of ultrasonography in primary HPT was fairly good and well correlated with the result of the 99m Tc-sestamibi scan, but both diagnostic modalities were not promising in secondary HPT.

    Color Doppler ultrasonographic(US) features of 28 patients with Hashimato's thyroiditis were evaluated with regard to echo and color-flow patterns. Correlation of color-flow pattern with thyroid function was performed. All 28 patients showed varying degrees of diffuse enlargement of the thyroid gland and a heterogeneous echo pattern.Color-flow pattern of increased blood flow. Low to moderate, focally increased blood flow was seen in 26 patients(92.8%). Of these 26 patients, 24 patients showed subclinical hypothyroidism or euthyroidism. Two patients who showed hyperthyroidism showed several pieces of focally increased color flow, Which was noted during both systole and diastole. Diffuse, multifocal color-flow throughout thyroid gland was seen in two patients with Hashimato's thyroiditis: one with clinical hypothyroidism and the other with subclinical hypothyroidism. Even though Hashimoto's thyroiditis showed variable color-flow patterns, we believe that heterogenous parenchymal echopattern with low or moderately increased flow is a rather characteristic feature of Hashimoto's thyroiditis, and we suggest that color Doppler US provides additional information for evaluation of Hashimoto's thyroiditis

    A serial-parallel dynamics simulator based on serial-parallel manipulator is proposed. According to the dynamics simulator motion requirement, the proposed serial-parallel dynamics simulator formed by 3-RRS (active revolute joint-revolute joint-spherical joint) and 3-SPR (Spherical joint-active prismatic joint-revolute joint) PMs adopts the outer and inner layout. By integrating the kinematics, constraint and coupling information of the 3-RRS and 3-SPR PMs into the serial-parallel manipulator, the inverse Jacobian matrix, velocity, and acceleration of the serial-parallel dynamics simulator are studied. Based on the principle of virtual work and the kinematics model, the inverse dynamic model is established. Finally, the workspace of the (3-RRS)+(3-SPR) dynamics simulator is constructed.

According to the dynamics simulator motion requirement, the proposed serial-parallel dynamics simulator formed by 3-RRS (active revolute joint-revolute joint-spherical joint) and 3-SPR (Spherical joint-active prismatic joint-revolute joint) PMs adopts the outer and inner layout. By integrating the kinematics, constraint and coupling information of the 3-RRS and 3-SPR PMs into the serial-parallel manipulator, the inverse Jacobian matrix, velocity, and acceleration of the serial-parallel dynamics simulator are studied. Based on the principle of virtual work and the kinematics model, the inverse dynamic model is established. Finally, the workspace of the (3-RRS)+(3-SPR) dynamics simulator is constructed

    Serial killers have always fascinated society. A serial killer is typically defined as a perpetrator who murders three or more people over a period of time. Most reported cases of serial killers come from the United States and Canada. In India, there are few reported cases. We present, to the best of our knowledge, the first Indian case in the literature. The present case is of a 28-year-old man, Surinder Koli. The Department of Forensic Medicine & Toxicology, All India Institute of Medical Sciences, New Delphi handled the forensic study. We present a most unique psychological investigation into the mind of a serial killer.

    AIM: To assess the relationship between initial CT pattern and serial changes in CT findings and pulmonary function tests (PFTs) in patients with non-specific interstitial pneumonia (NSIP). MATERIALS AND METHODS: Serial high resolution (HR) CTs and PFTs were retrospectively analyzed in 38 cases of histologically proven NSIP, including 4 with cellular NSIP, 13 with mixed cellular and fibrotic NSIP, and 21 with fibrotic NSIP. The presence and extent of various CT findings were assessed. A fibrosis index (defined as the ratio of the extent of a reticular/honeycomb pattern to the overall extent of abnormal parenchyma) was derived. RESULTS: The predominant CT pattern was reticular/honeycomb in 27 (84%) cases and ground-glass/consolidation in 6 (16%) cases. Between scans, mean disease extent reduced by 5.2%. Disease extent reduced by >10% in 13 (34%) and increased by >10% in 6 (16%) patients. Histopathological subtype of NSIP did not correlate with individual CT pattern, predominant pattern, fibrosis index or serial change in disease extent on CT or PFTs. Response on follow-up CT was associated with fibrosis index, predominant pattern and extent of consolidation on initial CT. CONCLUSION: In NSIP disease, progression on CT correlates with the predominant CT pattern, fibrosis index, and extent of consolidation but not with histopathological subtype. An inflammatory (ground-glass/consolidation) predominant pattern is associated with better outcome in terms of disease extent on HRCT.

    Crystal structure determination of biological macromolecules using the novel technique of serial femtosecond crystallography (SFX) is severely limited by the scarcity of X-ray free-electron laser (XFEL) sources. However, recent and future upgrades render microfocus beamlines at synchrotron-radiation sources suitable for room-temperature serial crystallography data collection also. Owing to the longer exposure times that are needed at synchrotrons, serial data collection is termed serial millisecond crystallography (SMX). As a result, the number of SMX experiments is growing rapidly, with a dozen experiments reported so far. Here, the first high-viscosity injector-based SMX experiments carried out at a US synchrotron source, the Advanced Photon Source (APS), are reported. Microcrystals (5-20 µm) of a wide variety of proteins, including lysozyme, thaumatin, phycocyanin, the human A 2A adenosine receptor (A 2A AR), the soluble fragment of the membrane lipoprotein Flpp3 and proteinase K, were screened. Crystals suspended in lipidic cubic phase (LCP) or a high-molecular-weight poly(ethylene oxide) (PEO; molecular weight 8 000 000) were delivered to the beam using a high-viscosity injector. In-house data-reduction (hit-finding) software developed at APS as well as the SFX data-reduction and analysis software suites Cheetah and CrystFEL enabled efficient on-site SMX data monitoring, reduction and processing. Complete data sets were collected for A 2A AR, phycocyanin, Flpp3, proteinase K and lysozyme, and the structures of A 2A AR, phycocyanin, proteinase K and lysozyme were determined at 3.2, 3.1, 2.65 and 2.05 Å resolution, respectively. The data demonstrate the feasibility of serial millisecond crystallography from 5-20 µm crystals using a high-viscosity injector at APS. The resolution of the crystal structures obtained in this study was dictated by the current flux density and crystal size, but upcoming developments in beamline optics and the planned APS

    To characterize the clinical, clinicopathologic, and imaging findings in dogs with intestinal lymphangiectasia and to compare the histologic grade of lymphangiectasia with clinicopathologic and imaging abnormalities. Retrospective study. 17 dogs with a histologic diagnosis of intestinal lymphangiectasia. Medical records of dogs with a histologic diagnosis of intestinal lymphangiectasia were reviewed for signalment, history, clinical signs, results of exploratory laparotomy, and clinicopathologic, radiographic, ultrasonographic, and histologic findings. Mean age of dogs was 8.3 years; the most common clinical signs were diarrhea, anorexia, lethargy, vomiting, and weight loss. Abnormal physical examination findings included dehydration, ascites, and signs of pain on palpation of the abdomen. The most notable clinicopathologic findings were low serum ionized calcium concentration and hypoalbuminemia. Abdominal ultrasonography was performed in 12 dogs and revealed intestinal abnormalities in 8 dogs and peritoneal effusion in 7 dogs. Exploratory laparotomy revealed abnormalities in 9 of 16 dogs including thickened small intestine, dilated lacteals, lymphadenopathy, and adhesions. On histologic examination of the small intestine, concurrent inflammation was observed in 15 of 17 dogs, crypt ectasia in 5 of 17, and lipogranulomas in 2 of 17. Intestinal lymphangiectasia in dogs appears to be a heterogeneous disorder characterized by various degrees of panhypoproteinemia, hypocholesterolemia, lymphocytopenia, and imaging abnormalities. In most dogs, the severity of hypoalbuminemia appears to offer the best correlation with severity of histologic lesions of lymphangiectasia. Imaging abnormalities are common in dogs with intestinal lymphangiectasia but are not specific enough to differentiate this disorder from other gastrointestinal disorders, nor are they predictive of histologic severity.

    Full Text Available Objective: Acute kidney injury is an important problem in neonates. We conducted a cross-sectional prospective study to determine normal serum blood urea nitrogen, creatinine reference ranges and ranges of ultrasonographic measurement of kidneys in healthy term newborns. Study Design: Blood samples were collected from total 357 healthy newborns at birth (n=45, 1st (n=30, 3rd (n=61, 7th (n=34, 10th (n=132, 14th (n=36, and 28th (n=19 days of life. Renal ultrasonographic was performed by the same two radiologists on 81 newborns aged 10 days. Results: Serum blood urea nitrogen and creatinine concentrations have reached to the highest level at the first day of life and have returned to cord level at the third day of life. There were gradually decrease in serum blood urea nitrogen and creatinine levels after the first day of life. There were significant difference in both right and left renal length, width, and volumes in terms of gender and these parameters were statistically higher in boys than girls (p<0.05. Birth weight of the boys (3548±539g was statistically higher than girls (3307±405 g (p=0.028. There was a positive correlation between birth weight and right (r=0.38, p=0.000 and left kidney volumes (r=0.44, p=0.000. Conclusion: Our findings showed that measured blood urea nitrogen and creatinine levels changed in accordance with postnatal days and there was a positive correlation between kidney volume and birth weight of newborns. We concluded that these findings are important for evaluation of acute kidney injury and for screening of for urinary tract anomalies in neonates

    To classify the cerebral cavernous malformations and to investigate the natural history of cavernous malformations according to the classification, 41 patients with 61 cavernous malformations (40 cavernous malformations from 22 patients treated with gamma knife surgery) were regularly followed up using MR imaging for a mean period of 25.5 months in treated cavernous malformations and 20.7 months in untreated cavernous malformations, respectively. Cavernous malformations were classified into four types. Follow-up MR images were analyzed to evaluate changes in size, signal intensity, rebleeding, and perilesional adverse reaction of irradiation. A total of 61 cavernous malformations including 17 in type I, 23 in type II, 10 in type III, and 11 in type IV showed usual degradation of blood product in 22 cavernous malformations, no change in shape and signal intensity in 31 cavernous malformations, and eight cavernous malformations with rebleedings in the serial MR images. In these eight cavernous malformations with rebleedings, six occurred in type II and two in type III, but none in type I or IV. Rebleedings were more frequent in type II than in other types. Adverse reaction of irradiation was observed in five of 22 patients treated with gamma knife surgery. Although most cerebral cavernous malformations showed evolution of hemorrhage or no change in size or shape on follow-up MR images, cerebral cavernous malformations represented as mixture of subacute and chronic hemorrhage with hemosiderin rim (type II) have a higher frequency to rebleed than other types of cerebral cavernous malformations. Cerebral cavernous malformations represented as hemosiderin deposition without central core (type IV) have a lower tendency to rebleed than other types and do not need any treatment. Most of the adverse reaction of irradiation after gamma knife surgery around cavernous malformations are transient findings and are considered to be perilesional edema. (K.H)

    The conventional message-passing schedule for LDPC decoding algorithms is the so-called flooding schedule. It has the disadvantage that the updated messages cannot be used until next iteration, thus reducing the convergence speed . In this case, the Layered Decoding algorithm (LBP) based on serial message-passing schedule is proposed. In this paper the decoding principle of LBP algorithm is briefly introduced, and then proposed its two improved algorithms, the grouped serial decoding algorithm (Grouped LBP) and the semi-serial decoding algorithm .They can improve LBP algorithm's decoding speed while maintaining a good decoding performance.

    A ten megabit per second serial data repeater system has been developed for the 6.28km Tevatron accelerator. The repeaters are positioned at each of the thirty service buildings and accommodate control and abort system communications as well as distribution of the Tevatron time and energy clocks. The repeaters are transparent to the particular protocol of the transmissions. Serial data are encoded locally as unipolar two volt signals employing the self-clocking Manchester Bi-Phase code. The repeaters modulate the local signals to low-power bursts of 50 MHz rf carrier for the 260m transmission between service buildings. The repeaters also demodulate the transmission and restructure the data for local utilization. The employment of frequency discrimination techniques yields high immunity to the characteristic noise spectrum

  17. From brief gaps to very long pauses: temporal isolation does not benefit serial recall.

    Nimmo, Lisa M; Lewandowsky, Stephan

    2005-12-01

    Theoretical explanations of short-term memory for serial order can be classified on the basis of whether or not they invoke time as a causal variable. According to time-based accounts, such as temporal distinctiveness theories, there is an intimate link between time and memory. Event-based theories, by contrast, postulate processes such as interference or rehearsal to account for seemingly temporal phenomena in short-term memory. We report an experiment that examined whether extended temporal isolation benefits serial recall performance. Regardless of whether the participants were quiet or performed articulatory suppression during list presentation, temporal isolation did not benefit memory even if items were separated from their neighbors by up to 7 sec. These findings challenge time-based theories of short-term memory.

    To compare the quality of ultrasonographic (US) images, tissue harmonic image (THI) versus fundamental image (FI), of the pancreas. During a recent 2 month period, forty one patients with the normal pancreas on US were included. All of them were free of abnormal clinical and laboratory findings suggestive of pancreatic disease, US was performed by an abdominal radiologist with a 2.5-5 MHz convex-array transducer (Sequoia 512: Acuson, Mountain View, Calif.U.S.A.). Comparison of THI and FI of the pancreas was done for the following parameters:conspicuity, intermal architecture, and delineation range. Grading was made by the consensus of two abdominal radiologist witha three-point scale. Statistical analysis was done using Wilcox signed rank sum test. For the evaluation of the US image quality of the pancreas THI showed better conspicuity (p=0.0130), clearer internal architecture (p=0.0029) and superior delineation range (p=0.0191) than those of FI. THI appears to show a superior image quality than FI in evaluation of the pancreas.

    Objectives The aim of the study was to describe the normal abdominal echoanatomy of the tigrina and to compare it with the abdominal echoanatomy of the domestic cat. Reference intervals for the normal abdominal ultrasonographic anatomy of individual species are important for accurate diagnoses and interpretation of routine health examinations. The hypothesis was that the echoanatomy of the tigrina was similar to that of the domestic cat. Methods Eighteen clinically healthy tigrina were selected for abdominal ultrasound examination, in order to obtain normal parameters of the bladder, spleen, adrenal gland, kidney, gastrointestinal tract, liver and gall bladder, and Doppler parameters of liver and kidney vessels. Results The splenic parenchyma was consistently hyperechoic to the kidneys and liver. The liver, kidneys and spleen had similar echotexture, shape and dimensions when compared with the domestic cat. The gall bladder was lobulated and surrounded by a clearly visualized thin, smooth, regular echogenic wall. The adrenal glands had a bilobulated shape. The urinary bladder had a thin echogenic wall. The Doppler parameters of the portal vein and renal artery were similar to the domestic cat. Conclusions and relevance The results support the hypothesis that the ultrasonographic parameters of the abdominal viscera of the southern tigrina are similar to those of the domestic cat.

    Full Text Available When it comes to lexical access in L2 speech production, working memory (WM seems to play a central role as for less automatized procedures require more WM capacity to be executed (Prebianca, 2007. With that in mind, this paper aims at claiming that bilingual lexical access qualifies as a controlled serial strategic search task susceptible to individual differences in WM capacity. Evidence in support of such claim is provided by the results of AUTHOR's (2010 study conducted so as to investigate the relationship between L2 lexical access, WMC and L2 proficiency. AUTHOR's (2010 findings indicate that bilingual lexical access entails underlying processes such as cue generation, set delimitation, serial search and monitoring, which to be carried out, require the allocation of attention. Attention is limited and, as a result, only higher spans were able to perform these underlying processes automatically.

    There are innumerable demonstrations of serial position functions-with characteristic primacy and recency effects-in episodic tasks, but there are only a handful of such demonstrations in semantic memory tasks, and those demonstrations have used only two types of stimuli. Here, we provide three more examples of serial position functions when recalling from semantic memory. Participants were asked to reconstruct the order of (1) two cartoon theme song lyrics, (2) the seven Harry Potter books, and (3) two sets of movies, and all three demonstrations yielded conventional-looking serial position functions with primacy and recency effects. The data were well-fit by SIMPLE, a local distinctiveness model of memory that was originally designed to account for serial position effects in short- and long-term episodic memory. According to SIMPLE, serial position functions in both episodic and semantic memory tasks arise from the same type of processing: Items that are more separated from their close neighbors in psychological space at the time of recall will be better remembered. We argue that currently available evidence suggests that serial position functions observed when recalling items that are presumably in semantic memory arise because of the same processes as those observed when recalling items that are presumably in episodic memory.

  2. Natural born killers?: the development of the sexually sadistic serial killer.

    Today's society seems enthralled with serial killers in the news and the media. Forensic psychiatrists often interview serial killers after they have been caught. There are retrospective studies and case reports of individuals who have committed sexually sadistic serial murders. However, there exists a dearth of case reports on adolescents who have expressed serious fantasies about becoming serial killer prior to actualizing their fantasy. This article presents nine clinical cases of 14- to 18-year-olds who have clinically significant fantasies of becoming a serial killer. Similarities exist in these adolescent cases when compared with retrospective studies and case reports of serial killers on the role of sexually sadistic fantasies and actual killings. Since it has been established that sexual paraphilias may develop at a young age, one can surmise that sadistic paraphilias may also develop in some adolescents. The question is posed, can we predict which of these adolescents may go on to actually become serial killers? This article focuses on how the sexually sadistic fantasy can eventually be acted out and possible motives for the act to be repeated multiple times. Finally, recommendations are made about assessing and treating a youngster who expresses violent sexually sadistic killing fantasies so that attempts can be made to interrupt the progression to actual killing.

    Despite weaknesses in the organized/disorganized classification of serial killers, it is drawn on for "offender profiles," theories of offending, and in murder trials. This dichotomy was therefore tested by the multidimensional scaling of the co-occurrence of 39 aspects of serial killings derived 100 murders committed by 100 U.S. serial killers. Results revealed no distinct subsets of offense characteristics reflecting the dichotomy. They showed a subset of organized features typical of most ...

    Ultrasonographic examination is not widely applied to chest disease, but is may give useful information when the acoustic window for a lesion exist. We did perform ultrasound examination in 68 cases of chest disease. 1. The cases of pleural diseases was predominant; pleural effusion 35 cases, pleural metastatic tumor 2 case, mesothelioma 2 cases and fibrous thickening 1 case, total 40 cases. It was useful to differentiate pleural effusion and fibrous thickening or parenchymal lesion simulating pleural disease, to localize the optimal aspiration site for a loculated empyema, to detect pleural bumorhidden by effusion such as metastatic tumor or mesothelioma. 2. 15 cases of parenchymal lesion and 2 cases of extra pleural mass was examined. The echo pattern of consolidation and atelectasis shows typical multiple tubular streaks within the echogenic area. The echogenicity of the peripheral mass due to primary bronchogenic carcinoma, parenchymal or extrapleural metastatic tumor and granuloma were compared. 3. In the cases of pleural or parenchymal cystic lesions, such as loculated empyema or lung abscess, because of strong reverberation artifact from posterior border of the lesion, the prediction of cystic and solid lesion is sometimes difficult. 4. In 7 cases of mediastinal lesion, cystic lesion show free echo and posterior enhancement. In contrast, solid or fat component show characteristic echo pattern. 5. In the cases of juxta diaphragmatic lesion, sonogram can confirm the underlying intraabdominal pathology, in this case subphrenic abscess

    A long-standing body of research supports the existence of separable short- and long-term memory systems, relying on phonological and semantic codes, respectively. The aim of the current study was to measure the contribution of long-term knowledge to short-term memory performance by looking for evidence of phonologically and semantically coded storage within a short-term recognition task, among developmental samples. Each experimental trial presented 4-item lists. In Experiment 1 typically developing children aged 5 to 6 years old showed evidence of phonologically coded storage across all 4 serial positions, but evidence of semantically coded storage at Serial Positions 1 and 2. In a further experiment, a group of individuals with Down syndrome was investigated as a test case that might be expected to use semantic coding to support short-term storage, but these participants showed no evidence of semantically coded storage and evidenced phonologically coded storage only at Serial Position 4, suggesting that individuals with Down syndrome have a verbal short-term memory capacity of 1 item. Our results suggest that previous evidence of semantic effects on "short-term memory performance" does not reflect semantic coding in short-term memory itself, and provide an experimental method for researchers wishing to take a relatively pure measure of verbal short-term memory capacity, in cases where rehearsal is unlikely.

    Accurate ventricle volume estimates could improve the understanding and diagnosis of postoperative communicating hydrocephalus. For this category of patients, associated changes in ventricle volume can be difficult to identify, particularly over short time intervals. We present an automated segmentation algorithm that evaluates ventricle size from serial brain MRI examination. The technique combines serial T1- weighted images to increase SNR and segments the means image to generate a ventricle template. After pre-processing, the segmentation is initiated by a fuzzy c-means clustering algorithm to find the seeds used in a combination of fast marching methods and geodesic active contours. Finally, the ventricle template is propagated onto the serial data via non-linear registration. Serial volume estimates were obtained in an automated robust and accurate manner from difficult data.

    The aim of the investigation was the comparison of the diagnostic value of the clinical, radiological and ultrasonographic examinations in the diagnosis of focal changes in the liver and the determination of the relations between the changes in the ultrasound image of the liver and the changes in other organs. The investigation was performed on 24 animals: 20 dogs and 4 cats of different breeds and sex, aged 1.5 to 14 years. The ultrasonographic examinations were done using the apparatus of Bruel and Kjaer type 1849 and Concept 2000 of Dynamic Imaging. The following changes were diagnosed in the ultrasonic picture: echogenic changes in 5 animals, hypoechogenic in 2 animals, normechogenic in 2 animals, hyperechogenic in 8 animals and changes of mixed echogenicity in 5 animals. The connection between clinical signs and the results of X-ray and ultrasonographic examination allowed the recognition of the changes in the liver as cysts, abscess and neoplasm of the liver.

    2011-02-01

    This comprehensive overview on a sample of 65 cases (134 total offenders, including some partnered teams of more than 2 offenders) provides information on female serial murderers who either work in a mixed-sex offending group or alone. These female serial homicide offenders have a distinct set of offender-victim characteristics, including specific victim preferences, methods, and motivations: Partnered serial homicide offenders are more likely to target adult strangers and dispatch them using a combination of methods, whereas solo female serial murderers are most likely to target adult family members and murder them with poison. These patterns have the potential to add to our understanding of the possible similarities and differences of serial homicide cases by building on established offender characteristics. Convictions and sentences for the offenders are included and areas of future research and implications for treatment with this sample are also explored.

    Does the world need yet another 1/0 bus standard? If you need fast and cheap serial video communication, then the answer is yes. As technology advances, so too must data transport mechanisms advance. You can`t expect RS-232 to support real-time digital video, and if you can`t afford expensive professional serial video interfaces, (such as Sony`s Serial Digital Interface), Firewire may be a good solution. IEEE 1394, or commonly known as Firewire, is a general purpose serial bus that meets many of the 1/0 needs of today`s video and multimedia developers. For those of you who only read the first paragraph, here`s Firewire in a nutshell: It provides a guaranteed transfer rate of 10OMbps or 20OMbps of digital data (such as video direct from camera to computer), over an inexpensive, non-proprietary serial bus. Here is a list of its features.

    To test the hypothesis that myometrial thickness predicts the success of external cephalic version. Abdominal ultrasonographic scans were performed in 114 consecutive pregnant women with breech singletons before an external cephalic version maneuver. Myometrial thickness was measured by a standardized protocol at three sites: the lower segment, midanterior wall, and the fundal uterine wall. Independent variables analyzed in conjunction with myometrial thickness were: maternal age, parity, body mass index, abdominal wall thickness, estimated fetal weight, amniotic fluid index, placental thickness and location, fetal spine position, breech type, and delivery outcomes such as final mode of delivery and birth weight. Successful version was associated with a thicker ultrasonographic fundal myometrium (unsuccessful: 6.7 [5.5-8.4] compared with successful: 7.4 [6.6-9.7] mm, P=.037). Multivariate regression analysis showed that increased fundal myometrial thickness, high amniotic fluid index, and nonfrank breech presentation were the strongest independent predictors of external cephalic version success (Pexternal cephalic versions (fundal myometrial thickness: odds ratio [OR] 2.4, 95% confidence interval [CI] 1.1-5.2, P=.029; amniotic fluid index: OR 2.8, 95% CI 1.3-6.0, P=.008). Combining the two variables resulted in an absolute risk reduction for a failed version of 27.6% (95% CI 7.1-48.1) and a number needed to treat of four (95% CI 2.1-14.2). Fundal myometrial thickness and amniotic fluid index contribute to success of external cephalic version and their evaluation can be easily incorporated in algorithms before the procedure. III.

    Organ shortage has led to using grafts from expanded criteria donors (ECD). Double kidney transplantation is an accepted strategy to increase the donor pool, using organs from an ECD which are not acceptable for single kidney transplantation (SKT). Aim of this retrospective study was to analyse the role of colour Doppler ultrasound (CDUS) in the diagnosis of major surgical complications in DKT, performed with unilateral or bilateral placement. From 2000 to 2011 we performed 54 DKT. Unilateral placement of both kidneys was done in 26 patients and bilateral DKT in 28, through two separate Gibson incisions (18) or one midline incision (10). Each patient underwent at least 3 CDUS before hospital discharge. The main surgical complications, discovered initially thanks to ultrasound (US), were hydronephrosis from ureteral obstruction, lymphocele and deep venous thrombosis (DVT). Mean follow-up was 42.7 months. Good postoperative renalfunction was demonstrated in 25 patients (46.3%), while delayed graft function occurred in 29 (53.7%). US showed ureteral obstruction requiring surgery in 5 unilateral DKT while no patient subjected to bilateral DKT developed severe hydronephrosis. Lymphoocele, surgically drained, was demonstrated in 6 bilateral DKT with a midline incision, 2 bilateral DKT with two separate incisions and 3 unilateral DKT. CDUS also enabled diagnosis of 2 cases of DVT in ipsilateral DKTs. CDUS provides useful information in patients with DKT, allowing the detection of clinically unsuspected unilateral diseases. US study of our patients demonstrated that unilateral DKTs are more susceptible to the development of DVT and ureteral stricture, while the incidence of voluminous lymphocele is more frequent in bilateral DKT through a single midline incision. In this scenario, all patients undergoing DKT should be carefully monitored by US after surgery.

    The purpose of this study was to evaluate the usefulness of a computer-aided diagnosis (CAD) scheme for improving the performance of clinicians to diagnose non-mass lesions appearing as hypoechoic areas on breast ultrasonographic images. The database included 97 ultrasonographic images with hypoechoic areas: 48 benign cases [benign lesion with benign mammary tissue or fibrocystic disease (n = 20), fibroadenoma (n = 11), and intraductal papilloma (n = 17)] and 49 malignant cases [ductal carcinoma in situ (n = 17) and invasive ductal carcinoma (n = 32)]. Seven clinicians, three expert breast surgeons, and four general surgeons participated in the observer study. They were asked their confidence level concerning the possibility of malignancy in all 97 cases with and without the use of the CAD scheme. Receiver operating characteristic (ROC) analysis was performed to evaluate the usefulness of the CAD scheme. The areas under the ROC curve (AUC) improved for all observers when they used the CAD scheme and increased from 0.649 to 0.783 (P = 0.0167). Notably, the AUC for the general surgeon group increased from 0.625 to 0.793 (P = 0.045). This study showed that the performance of clinicians to diagnose non-mass lesions appearing as hypoechoic areas on breast ultrasonographic images was improved by the use of a CAD scheme.

    To evaluate the possible radial nerve entrapment of patients with unilateral refractory lateral epicondylitis (LE) by using ultrasound (US) and electroneuromyography. Cross-sectional study. Three physical medicine and rehabilitation departments. Consecutive 44 patients (15 M, 29 F) with unilateral refractory LE. All patients underwent detailed clinical, electrophysiological and ultrasonographic evaluations. Ultrasound imaging was used to evaluate thickness and presence of abnormal findings of the common extensor tendon (CET) and cross-sectional area (CSA) of the radial nerve (at spiral groove and before bifurcation) bilaterally. Unaffected sides of the patients were taken as controls. When compared with the unaffected sides, CET thickness and radial nerve CSAs (at both levels) were higher, and abnormal US findings regarding LE (47.7% vs. 6.8%) were more common on the affected sides than nonaffected sides (all P   0.05). When subgroup analyses were performed after taking into account the hand dominance, affected and dominant sides were found to be the same in 31 and different in 13 patients. In subgroups, CETs and radial nerve CSAs at both levels were higher on the affected sides (all P  < 0.01). Radial nerves and the CETs seem to be swollen on the affected sides, independent from the hand dominance of the patients with refractory LE. These results morphologically support the previous literature that attributes some of the chronic complaints of these patients actually to radial nerve entrapment. © 2016 American Academy of Pain Medicine.

    To explore the effect of acupuncture on common extensor tendon (CET) thickness in patients with lateral epicondylitis (LE). Additionally, to identify whether clinical and ultrasonographic changes showed any correlation. Forty-one patients were randomly assigned to acupuncture and control groups. Conventional treatment (rest, NSAİİ, bracing, exercise) methods for LE were applied to all patients. In addition to this, the acupuncture treatment was applied to the acupuncture group. The visual analog scale (VAS) for pain, the Duruoz Hand Index (DHI) for functioning of the affected limb, the pressure pain threshold, and CET thickness (via ultrasound imaging) were assessed before and end of the treatment in both groups. The VAS and DHI scores in both groups decreased. The pressure pain threshold and CET thickness only demonstrated improvement in the acupuncture group. These findings show that the CET thickness was reduced after 10 sessions of acupuncture treatment in LE patients.

    Ultrasonography was used to evaluate the ventral midline incisions of 21 ponies following exploratory laparotomy. The incisions were evaluated before surgery and at weekly intervals from one to seven weeks after surgery. Both 5.0 and 7.5 MHz linear array and 7.5 MHz sector transducers were used for the evaluations. The incisional complications observed were drainage, oedema, suture sinus formation, suture abscess, superficial dehiscence and incisional hernia. Ultrasonographic imaging of the ventral midline incision was an easy, reliable and objective method for detecting and monitoring the progression of incisional complications in a non-invasive manner.

    The purpose of this study was to evaluate the ultrasonographic (US) features of traumatic neuromas in breast cancer patients after mastectomy. This study was performed with approval from our Institutional Review Board, and the requirement for informed consent was waived. Six traumatic neuromas in five patients were included in this study. The US findings of traumatic neuromas were evaluated retrospectively by two radiologists according to the Breast Imaging-Reporting and Data System (BI-RADS) lexicon. The final assessment was also recorded. On US, all six lesions presented as a mass within the pectoralis muscle layer (mean size, 4.8 mm; range, 3.9 to 5.5 mm). Of the six masses, four had an oval shape with a circumscribed margin, and two had an irregular shape and an indistinct margin. They were all hypoechoic. Two lesions showed a non-parallel orientation. On color Doppler examinations, two lesions showed internal vascularity. Strain elastography was performed for four neuromas, resulting in scores of 1 (n=1), 4 (n=2), and 5 (n=1). The final assessment categories were BI-RADS 3 (n=2), 4A (n=2), and 4B (n=2). On US, an oval shape, circumscribed margin, parallel orientation, and hypoechogenicity were the most frequent features of traumatic neuromas in breast cancer patients after mastectomy. Neuromas may show increased vascularity on color Doppler imaging and present as a hard mass on elastography.

    Early embryonic resorption or fetal loss is known to occur occasionally in captive elephants; however, this has mostly been reported anecdotally. The present study documents the case of a 24-year-old, multiparous Asian elephant cow that suffered embryonic death and resorption at around 18 weeks of gestation. From ovulation onwards, this female was sonographically examined 58 times. Blood was collected twice weekly for progestagen determination via enzyme immunoassay. On Day 42 after ovulation, a small quantity of fluid was detected in the uterine horn, which typically indicates the presence of a developing conceptus. Repeated inspections followed what appeared to be a normal pregnancy until Day 116. However, on Day 124, signs of embryonic life were absent. Progestagen concentrations started declining two weeks later, reaching baseline levels one month after embryonic death. Retrospectively, ultrasound examination revealed several abnormalities in the uterine horn. Besides an existing leiomyoma, multiple small cystic structures had formed in the endometrium at the implantation site and later in the placenta. These pathological findings were considered as possible contributors to the early pregnancy failure. PCR for endotheliotropic elephant herpes virus (EEHV) (which had occurred previously in the herd) as well as serology for other infectious organisms known to cause abortion in domestic animals did not yield any positive results. Although no definitive reason was found for this pregnancy to abort, this ultrasonographically and endocrinologically documented study of an early pregnancy loss provides important insights into the resorption process in Asian elephants.

    Serial-order short-term memory (STM), as opposed to item STM, has been shown to be very consistently associated with lexical learning abilities in cross-sectional study designs. This study investigated longitudinal predictions between serial-order STM and vocabulary development. Tasks maximizing the temporary retention of either serial-order or item information were administered to kindergarten children aged 4 and 5. At age 4, age 5, and from age 4 to age 5, serial-order STM capacities, but not item STM capacities, were specifically associated with vocabulary development. Moreover, the increase of serial-order STM capacity from age 4 to age 5 predicted the increase of vocabulary knowledge over the same time period. These results support a theoretical position that assumes an important role for serial-order STM capacities in vocabulary acquisition.

    The dystroglycanopathies are a heterogeneous group of conditions, with mutations in B3GALNT2 described in association with congenital muscular dystrophy. The serial prenatal MRI findings in this disorder have not been well described. We present sequential prenatal and postnatal MRI findings in a boy with compound heterozygous mutations in B3GALNT2, as well as the MRI findings of his two siblings with similar mutations. These findings provide new insight into the molecular pathogenesis and neurodevelopment of congenital muscular dystrophy. (orig.)

    Fluoroscopically guided, percutaneous antegrade pyelography in canine patients has been described previously in the veterinary literature. This report describes the technique with ultrasonographic guidance and its clinical application in the diagnosis of four cases (two dogs, two cats) of obstructive uropathy. The technique provided successful diagnosis of ureteral obstruction in all four cases. No complications were observed in three cases. In one feline case, ureteral obstruction with a blood clot occurred following the procedure; however, it could not be ascertained whether this event represented a complication of the technique

    In this paper, based on the equivalent single diode circuit model of the solar cell, an equivalent circuit diagram for two serial solar cells is drawn. Its equations of current and voltage are derived from Kirchhoff's current and voltage law. First, parameters are obtained from the I—V (current—voltage) curves for typical monocrystalline silicon solar cells (125 mm × 125 mm). Then, by regarding photo-generated current, shunt resistance, serial resistance of the first solar cell, and resistance load as the variables. The properties of shunt currents (I sh1 and I sh2 ), diode currents (I D1 and I D2 ), and load current (I L ) for the whole two serial solar cells are numerically analyzed in these four cases for the first time, and the corresponding physical explanations are made. We find that these parameters have different influences on the internal currents of solar cells. Our results will provide a reference for developing higher efficiency solar cell module and contribute to the better understanding of the reason of efficiency loss of solar cell module.

    Working memory refers to our ability to actively maintain and process a limited amount of information during a brief period of time. Often, not only the information itself but also its serial order is crucial for good task performance. It was recently proposed that serial order is grounded in spatial cognition. Here, we compared performance of a group of right hemisphere-damaged patients with hemispatial neglect to healthy controls in verbal working memory tasks. Participants memorized sequences of consonants at span level and had to judge whether a target consonant belonged to the memorized sequence (item task) or whether a pair of consonants were presented in the same order as in the memorized sequence (order task). In line with this idea that serial order is grounded in spatial cognition, we found that neglect patients made significantly more errors in the order task than in the item task compared to healthy controls. Furthermore, this deficit seemed functionally related to neglect severity and was more frequently observed following right posterior brain damage. Interestingly, this specific impairment for serial order in verbal working memory was not lateralized. We advance the hypotheses of a potential contribution to the deficit of serial order in neglect patients of either or both (1) reduced spatial working memory capacity that enables to keep track of the spatial codes that provide memorized items with a positional context, (2) a spatial compression of these codes in the intact representational space. © 2018 The British Psychological Society.

    Conditioning by early training may influence the composition of certain musculoskeletal tissues, but very few data exist on its effect during growth on tendon structure and function. To investigate whether conditioning exercise in young foals would lead to any ultrasonographically detectable damage to the superficial digital flexor tendon or an increase in cross-sectional area (CSA). Thirty-three Thoroughbred foals reared at pasture were allocated to 2 groups: control (PASTEX) allowed exercise freely at pasture; and CONDEX, also at pasture, began conditioning exercise from mean age 21 days over 1030 m on a purpose-built oval grass track, for 5 days/week until mean age 18 months. Foals were observed daily, and underwent orthopaedic examination monthly. Ultrasonographic images of the superficial digital flexor tendon (SDFT) at the mid-metacarpal level of both forelimbs were obtained in all foals at ages 5, 8, 12, 15 and 18 months. CSA was validated (r(2) = 0.89) by determining CSA from digital photographs of the transected SDFT surface from 12 of the horses necropsied at age 17.1 months. here was no clinical or ultrasonographic evidence of tendonopathy in either group and the greatest increase in mean CSA in both groups occurred between age 5 and 8 months. Across all age categories, there was no significant difference in mean CSA between the left and right limbs, or colts and fillies; there was a trend towards a larger CSA in the CONDEX group (P = 0.058). There was no conclusive evidence for a structural adaptive hypertrophy of the SDFT, probably because the regimen was insufficiently rigorous or because spontaneous pasture exercise may induce maximal development of energy storing tendons. A moderate amount of early conditioning exercise against a background of constant exercise at pasture is not harmful to the development of the flexor tendons.

    Purpose: This study was designed to compare the effectiveness of systemic methotrexate (MTX) with uterine artery embolization (UAE) combined with local MTX for the treatment of cesarean scar pregnancy (CSP) with different ultrasonographic pattern, and to indicate the preferable therapy in CSP patients. Methods: The results of 21 CSP cases were reviewed. All subjects were initially administrated with systemic MTX (50 mg/m 2 body surface area). UAE combined with local MTX was added to the patients who had failed systemic MTX. The transvaginal ultrasonography data were retrospectively assessed, and two different ultrasonographic patterns were found: surface implantation and deep implantation of amniotic sac. The management and its effectiveness for patients with the two ultrasonographic patterns were studied retrospectively. Ultrasound scan and serum β-hCG were monitored during follow-up. Data were analyzed with the Student’s t test. Results: Nine patients were successfully treated with systemic MTX. The remaining 12 cases were successfully treated with additional UAE combined with local MTX. According to the classification by Vial et al. of CSP on ultrasonography, most surface implanted CSPs (8/11, 72.7%) could be successfully treated with systemic MTX, whereas most deeply implanted CSPs (9/10, 90%) had failed systemic MTX but still could be successfully treated with additional UAE combined with local MTX. All patients recovered without severe side effects. Most patients with a future desire for reproduction achieved subsequent pregnancy. Conclusions: For CSP patients suitable for nonsurgical treatment, UAE combined with local MTX would be the superior option compared with systemic MTX in the cases with deep implantation of amniotic sac.

  16. Attractive Serial Dependence in the Absence of an Explicit Task.

    Attractive serial dependence refers to an adaptive change in the representation of sensory information, whereby a current stimulus appears to be similar to a previous one. The nature of this phenomenon is controversial, however, as serial dependence could arise from biased perceptual representations or from biased traces of working memory representation at a decisional stage. Here, we demonstrated a neural signature of serial dependence in numerosity perception emerging early in the visual processing stream even in the absence of an explicit task. Furthermore, a psychophysical experiment revealed that numerosity perception is biased by a previously presented stimulus in an attractive way, not by repulsive adaptation. These results suggest that serial dependence is a perceptual phenomenon starting from early levels of visual processing and occurring independently from a decision process, which is consistent with the view that these biases smooth out noise from neural signals to establish perceptual continuity.

    The aim of the current research was to provide a novel method for mapping the developmental sequences of serial killers' life histories. An in-depth biographical account of serial killers' lives, from birth through to conviction, was gained and analyzed using Behavior Sequence Analysis. The analyses highlight similarities in behavioral events across the serial killers' lives, indicating not only which risk factors occur, but the temporal order of these factors. Results focused on early childhood environment, indicating the role of parental abuse; behaviors and events surrounding criminal histories of serial killers, showing that many had previous convictions and were known to police for other crimes; behaviors surrounding their murders, highlighting differences in victim choice and modus operandi; and, finally, trial pleas and convictions. The present research, therefore, provides a novel approach to synthesizing large volumes of data on criminals and presenting results in accessible, understandable outcomes.

    The prosecution of Charles Cullen, a nurse who killed at least 40 patients over a 16-year period, highlights the need to better understand the phenomenon of serial murder by healthcare professionals. The authors conducted a LexisNexis search which yielded 90 criminal prosecutions of healthcare providers that met inclusion criteria for serial murder of patients. In addition we reviewed epidemiologic studies, toxicology evidence, and court transcripts, to provide data on healthcare professionals who have been prosecuted between 1970 and 2006. Fifty-four of the 90 have been convicted; 45 for serial murder, four for attempted murder, and five pled guilty to lesser charges. Twenty-four more have been indicted and are either awaiting trial or the outcome has not been published. The other 12 prosecutions had a variety of legal outcomes. Injection was the main method used by healthcare killers followed by suffocation, poisoning, and tampering with equipment. Prosecutions were reported from 20 countries with 40% taking place in the United States. Nursing personnel comprised 86% of the healthcare providers prosecuted; physicians 12%, and 2% were allied health professionals. The number of patient deaths that resulted in a murder conviction is 317 and the number of suspicious patient deaths attributed to the 54 convicted caregivers is 2113. These numbers are disturbing and demand that systemic changes in tracking adverse patient incidents associated with presence of a specific healthcare provider be implemented. Hiring practices must shift away from preventing wrongful discharge or denial of employment lawsuits to protecting patients from employees who kill.

    The diagnosis of carpal tunnel syndrome (CTS) is mainly based on clinical findings and electrodiagnostic tests (EDT). However, EDT results do not support clinical findings in some cases. It has been recently suggested that ultrasonography (US) can be used to diagnose CTS. In this study, we aimed to investigate whether US has a diagnostic value for CTS in patients with negative EDT findings or not. EDT was performed on 319 wrists with clinical CTS findings in electrophysiology laboratory. Median and ulnar nerve conduction velocities were measured in all cases and electromyography was performed in patient with tenar atrophy and having suspicion involvement of brachial plexus as EDT. Fifty-nine wrists with negative EDT (study group) and 30 wrists from 15 healthy individuals (control group) were examined using US. The mean of cross-sectional areas (CSAs) measurements were found 8.83 ± 3.05 mm 2 by tracing method (TM) and 8.51 ± 3.13 mm 2 by ellipsoid formula (EF) in study group, and 7.63 ± 1.52 mm 2 by TM and 7.66 ± 1.42 mm 2 by EF in control group. The differences between study group and control group according to both TM and EF were significant (t-test p = 0.0079, p = 0.0460, respectively). In study group, CSAs were larger than 10.5 mm 2 in 18 (30.51%) and 16 (27.12%) wrists according to TM and EF findings, respectively, and in only one wrist (3.33%) in control group by both TM and EF. The differences of ultrasonographic CTS numbers between study group and control group were significant (p = 0.0024 by TM, p = 0.0086 by EF). We confirmed the usefulness of quantitative US assessment in the diagnosis of CTS in the patients with negative EDT findings. If EDT findings are inadequate to confirm the CTS in the patients with clinical CTS, US studies may be helpful to diagnose

    Mild cognitive impairment (MCI) is often associated with the preclinical phase of Alzheimer's disease (AD). Special scoring of word-list recall data for serial position has been suggested to improve discrimination of normal aging from dementia. We examined serial position effects in word-list recall for MCI participants compared to Alzheimer patients and controls. Individuals with MCI, like Alzheimer patients, had a diminished primacy effect in recalling words from a list. No alternative scoring system was better than standard scoring of word-list recall in distinguishing MCI patients from controls. Retention weighted scoring improved the discrimination of MCI and AD groups.

    We build a Geographic Profiling Model to generate the criminal's geographical profile, by combining two complementary strategies: the Spatial Distribution Strategy and the Probability Distance Strategy. In the first strategy, we designate the mean of all the known crime sites as the anchor point, and build a Standard Deviational Ellipse Model, considering the effect of landscape. In the second strategy, we take many factors such as the buffer zone and distance decay theory into consideration and calculate the probability of the offender's residence in a certain area by using the Bayesian Theorem and the Rossmo Algorithm. Then, we combine the result of two strategies and get three search areas suit different conditions of the police to track the serial criminal. Apply the model to the English serial killer Peter Sutcliffe's case, the calculation result shows that the model can effectively be used to track serial criminal.

    The ability to maintain the serial order of events is recognized as a major function of working memory. Although general models of working memory postulate a close link between working memory and attention, such a link has so far not been proposed specifically for serial-order working memory. The present study provided the first empirical demonstration of a direct link between serial order in verbal working memory and spatial selective attention. We show that the retrieval of later items of a sequence stored in working memory-compared with that of earlier items-produces covert attentional shifts toward the right. This observation suggests the conceptually surprising notion that serial-order working memory, even for nonspatially defined verbal items, draws on spatial attention.

    2016-03-01

    Full Text Available Serial femtosecond X-ray crystallography (SFX has created new opportunities in the field of structural analysis of protein nanocrystals. The intensity and timescale characteristics of the X-ray free-electron laser sources used in SFX experiments necessitate the analysis of a large collection of individual crystals of variable shape and quality to ultimately solve a single, average crystal structure. Ensembles of crystals are commonly encountered in powder diffraction, but serial crystallography is different because each crystal is measured individually and can be oriented via indexing and merged into a three-dimensional data set, as is done for conventional crystallography data. In this way, serial femtosecond crystallography data lie in between conventional crystallography data and powder diffraction data, sharing features of both. The extremely small sizes of nanocrystals, as well as the possible imperfections of their crystallite structure, significantly affect the diffraction pattern and raise the question of how best to extract accurate structure-factor moduli from serial crystallography data. Here it is demonstrated that whole-pattern fitting techniques established for one-dimensional powder diffraction analysis can be feasibly extended to higher dimensions for the analysis of merged SFX diffraction data. It is shown that for very small crystals, whole-pattern fitting methods are more accurate than Monte Carlo integration methods that are currently used.

    Fibroadenoma is a common benign breast lesion and its malignant transformation is rare. There have been several case reports and studies that retrospectively reviewed breast cancers that arose within fibroadenomas; however, none of these studies reported serial changes in radiologic features of the cancer, including findings from mammography and ultrasound (US). We report a case of breast cancer arising adjacent to an involuting fibro adenoma in a 39-year-old woman who was undergoing serial follow-up after her fibroadenoma was diagnosed. Seven years after her diagnosis, the lesion showed evidence of coarse calcifications, a typical sign of involution. Four years later, US revealed a newly developed hypoechoic lesion with irregular margins and peripherally located calcifications adjacent to the fibroadenoma. A core biopsy was performed, and histopathological examination resulted in a diagnosis of invasive ductal carcinoma. When new suspicious features are observed in a fibroadenoma, radiologists should raise the concern for breast cancer and proceed with diagnosis and treatment accordingly. PMID:26472981

    AUTHOR|(CDS)2080243; Marchioro, Alessandro; Ottavi, Marco

    This Ph.D. thesis focuses on the development and the characterization of novel solutions for electronic systems for high-speed data transmission in extremely high radio-active environment (e.g. high energy physics application). The text proposes two alternative full-custom solutions for a fundamental enabling block for a lowpower serial data transmission system, the serializer. This block will find place in a future transceiver conceived for the future upgraded phase of the Large Hadron Collider, or LHC, at CERN. The first solution proposed, called “triple module redundancy”, is based on hardware redundancy, a well-known solution, to obtain protection against the temporary malfunctioning induced by radiation. In the second case a new architecture, called “code protected”, is proposed. This architecture takes advantage of the error correction code present in the data word to obtain radiation robustness on data and some parts of the control logic and to further reduce the power consumption.

    Full Text Available The complex and multisided study of serial killers is partly made difficult by the current level of progress that has led these deviant people to evolve in relation to the aspects of shrewdness (concerning the staging and mobility. Despite the important work of some scholars who proposed important theories, all this shows that, concerning serial murders, it is still particularly frequent not to pay attention to links among homicides committed by the same person but in different parts of the world. It is therefore crucial to develop a worldwide database that allows all police forces to access information collected on crime scenes of murders which are particularly absurd and committed without any apparent reason. It will then be up to the profiler, through ad hoc and technologically advanced tools, to collect this information on the crime scene that would be made available to all police forces thanks to the worldwide database.

    Full Text Available Numerical simulations of 1D Burgers equation and 2D sloshing problem were carried out to study numerical discrepancy between serial and parallel computations. The numerical domain was decomposed into 2 and 4 subdomains for parallel computations with message passing interface. The numerical solution of Burgers equation disclosed that fully explicit boundary conditions used on subdomains of parallel computation was responsible for the numerical discrepancy of transient solution between serial and parallel computations. Two dimensional sloshing problems in a rectangular domain were solved using OpenFOAM. After a lapse of initial transient time sloshing patterns of water were significantly different in serial and parallel computations although the same numerical conditions were given. Based on the histograms of pressure measured at two points near the wall the statistical characteristics of numerical solution was not affected by the number of subdomains as much as the transient solution was dependent on the number of subdomains.

    Purpose: To evaluate the radiological, ultrasonographic, and magnetic resonance imaging (MRI) findings of idiopathic granulomatous mastitis. Material and Methods: Between April 2002 and June 2005, the mammography, ultrasound, color Doppler ultrasound, non enhanced MR, and dynamic MR findings of nine patients with the preliminary clinical diagnosis of malignancy and the final diagnosis of granulomatous mastitis were evaluated. Results: On mammography, asymmetrical focal densities with no distinct margins, ill-defined masses with spiculated contours, and bilateral multiple ill-defined nodules were seen. On ultrasound, in four patients a discrete, heterogenous hypoechoic mass, in two patients multiple abscesses, in one patient bilateral multiple central hypo peripheral hyperechoic lesions, in two patients heterogeneous hypo- and hyperechoic areas together with parenchymal distortion, and in one patient irregular hypoechoic masses with tubular extensions and abscess cavities were seen. Five of the lesions were vascular on color Doppler ultrasound. On MR mammography, the most frequent finding was focal or diffuse asymmetrical signal intensity changes that were hypointense on T1W images and hyperintense on T2W images, without significant mass effect. Nodular lesions were also seen. On dynamic contrast-enhanced mammography, mass-like enhancement, ring-like enhancement, and nodular enhancement were seen. The time-intensity curves differed from patient to patient and from lesion to lesion. Conclusion: The imaging findings of idiopathic granulomatous mastitis have a wide spectrum, and they are inconclusive for differentiating malignant and benign lesions

    2018-04-01

    Recent studies suggest that the mechanisms involved in the short-term retention of serial order information may be shared across short-term memory (STM) domains such as verbal and visuospatial STM. Given the intrinsic sequential organization of musical material, the study of STM for musical information may be particularly informative about serial order retention processes and their domain-generality. The present experiment examined serial order STM for verbal and musical sequences in participants with no advanced musical expertise and experienced musicians. Serial order STM for verbal information was assessed via a serial order reconstruction task for digit sequences. In the musical domain, serial order STM was assessed using a novel melodic sequence reconstruction task maximizing the retention of tone order information. We observed that performance for the verbal and musical tasks was characterized by sequence length as well as primacy and recency effects. Serial order errors in both tasks were characterized by similar transposition gradients and ratios of fill-in:infill errors. These effects were observed for both participant groups, although the transposition gradients and ratios of fill-in:infill errors showed additional specificities for musician participants in the musical task. The data support domain-general serial order STM effects but also suggest the existence of additional domain-specific effects. Implications for models of serial order STM in verbal and musical domains are discussed.

The visual system may therefore delicately balance the need to optimize sensitivity to image changes (e.g., by adapting to changes in color, orientation, object identity, etc with the desire to represent the temporal continuity of objects—the likelihood that objects perceived at this moment tend to exist in subsequent moments. One way that the visual system may promote such stability is through the introduction of serial dependence to visual perception: by biasing the current percept toward what was seen at previous moments, the brain could compensate for variability in visual input that might otherwise disrupt perceptual continuity. Here, in two sets of experiments, we tested for serial dependence in visual perception of orientation and facial expression. We found that on a given trial, a subject's perception of the orientation of a grating reflected not only the currently viewed stimulus, but also a systematic attraction toward the orientations of the previously viewed stimuli. We found the same serial dependence in the perception of facial expression. This perceptual attraction extended over several trials and seconds, and displayed clear tuning to the difference (in orientation or facial expression between the sequential stimuli. Furthermore, serial dependence in object perception was spatially specific and selective to the attended object within a scene. Several control experiments showed that the perceptual serial dependence we report cannot be explained by effects of priming, known hysteresis effects, visual short-term memory, or expectation. Our results reveal a systematic influence of recent visual experiences on perception at any given moment: visual percepts, even of unambiguous stimuli, are attracted toward what was previously seen. We propose that such serial dependence helps to maintain

    Recent findings suggest that the immediate free recall (IFR) of short lists is similar to immediate serial recall (ISR). These findings were obtained using a methodology in which participants did not know the list length in advance of each list, and this uncertainty may have encouraged participants to adopt atypical recall strategies. Therefore,…

    A high speed, low power 16:1 serializer has been developed with a commercial 0.25 μm silicon-on-sapphire CMOS technology. The serializer operates from 4.0 to 5.7 Gbps. Total jitter is 62 ps and the eye openning of the bathtub curve is 122 ps at bit rate error of 10-12 at 5 Gbps. Power consumption is 463 mW at 5 Gbps. A proton beam test indicates the serializer is suitable for applications in high energy physics experiments.

    Full Text Available Background: The proper evaluation of the pelvic floor muscles (PFM is essential for choosing the correct treatment. Currently, there is no gold standard for the assessment of female PFM function. Objective: To determine the correlation between vaginal palpation, vaginal squeeze pressure, and electromyographic and ultrasonographic variables of the female PFM. Method: This cross-sectional study evaluated 80 women between 18 and 35 years of age who were nulliparous and had no pelvic floor dysfunction. PFM function was assessed based on digital palpation, vaginal squeeze pressure, electromyographic activity, bilateral diameter of the bulbocavernosus muscles and the amount of bladder neck movement during voluntary PFM contraction using transperineal bi-dimensional ultrasound. The Pearson correlation was used for statistical analysis (p<0.05. Results: There was a strong positive correlation between PFM function and PFM contraction pressure (0.90. In addition, there was a moderate positive correlation between these two variables and PFM electromyographic activity (0.59 and 0.63, respectively and movement of the bladder neck in relation to the pubic symphysis (0.51 and 0.60, respectively. Conclusions: This study showed that there was a correlation between vaginal palpation, vaginal squeeze pressure, and electromyographic and ultrasonographic variables of the PFM in nulliparous women. The strong correlation between digital palpation and PFM contraction pressure indicated that perineometry could easily be replaced by PFM digital palpation in the absence of equipment.

    Full Text Available Embryonic mortality is one of the main causes responsible of the decline in fertility that occurs in buffaloes during periods of increasing daylight length (out sexual breeding season. Transrectal ultrasonography for pregnancy diagnosis offers some advantages over palpation per rectum: earlier diagnosis of pregnancy/non-pregnancy, determination of embryo/fetus viability, reduction of misdiagnosis, and reduction of .potential. iatrogenic embryo/fetal attrition. Non pregnant buffaloes on Day 25 after AI showed higher Resistive Index (RI (P<0.05 and Pulsatility Index (P=0.07 values, registered on CL on Days 10 after AI, compared to pregnant buffaloes. RI values were significantly higher (P=0.02 in non pregnant buffaloes also on Day 45 after AI. Colour Doppler sonography could be used to gain specific information relating to the ovarian blood flow in predicting early embryonic loss and to describe the ultrasonographic features of early embryonic death in buffaloes.
