Objectives-To evaluate renal parenchymal elasticity with acoustic radiation force impulse imaging in pediatric patients with chronic kidney disease (CKD) and compare with healthy volunteers. Methods-Thirty-eight healthy volunteers and 30 pediatric CKD patients were enrolled in this prospective study. The shear wave velocity (SW) values of both kidneys in CKD patients and healthy volunteers were evaluated. Results-The mean SW in healthy volunteers was 2.2160.34 m/s, whereas the same value was 1.81 +/- 0.49, 1.72 +/- 0.63, 1.66 +/- 0.29, 1.48 +/- 0.37, and 1.23 +/- 0.27 for stages 1, 2, 3, 4, and 5 in CKD patients, respectively. The S . . .W was significantly lower for each stage in the CKD patients compared with healthy volunteers. Acoustic radiation force impulse could not predict the different stages of CKD, with the exception of stage 5. The cut-off value for predicting CKD was 1.81 m/s; at this threshold, sensitivity was 76.5% and specificity was 92.1% (area under the curve = 0.870 [95% confidence interval: 0.750-0.990]; P < .001). Interobserver agreement expressed as intraclass coefficient correlation was 0.65 (95% confidence interval: 0.34 to 0.83; P < .001). Conclusions-Acoustic radiation force impulse may be a potentially useful tool in detecting CKD in pediatric patients Daha fazlası Daha az

Screw migration in a 14-year-old boy with hip osteotomy. A case of a rare cause of upper thigh hematoma

Soft tissue injury due to orthopedic hardware migration is an uncommon complication. However particularly patients who have routine physical therapy sessions for extremity contractures are at risk for vascular injury in the setting of migrated screws. Ultrasound is an efficient modality to evaluate migrated screws and adjacent soft tissue structures. As a consequence of repetitive trauma a migrated screw would eventually result in injury. Herein a case of upper thigh hematoma due to screw migration in a patient with hip osteotomy is reported.

Aberrant cervical thymus and the role of ultrasonography: A case report

Ectopic/aberrant cervical thymic tissue is a rare cause of neck mass and usually detected incidentally. Aberrant thymic tissue can occur anywhere in the course of thymic descent from the angle of the mandible to the superior mediastinum. We report a case of aberrant cervical thymus demonstrated by ultrasound.

In the intensive care unit (ICU), stable hemodynamics are very important. Hemodynamic intervention is often effective against multiple organ failure, such as in tissue hypoxia and shock. The administration of intravenous fluids is the first step in regulating tissue perfusion. The main objective of this study is to compare the performance between 2 methods namely pleth variability index (PVI) and IVC distensibily index (dIVC). In this study, the hemodynamic measurements were performed before and after passive leg raising (PLR). Measurements were obtained, including, PVI, dIVC, and cardiac index (CI). Both CI and dIVC measurements we . . .re evaluated by transesophageal probe and convex probe respectively. The dIVC measurements were taken using M-mode, 2cm from junction between the right atrium and the inferior vena cava. The PVI was measured by Masimo Radical-7 monitor, Masimo. A total of 72 patients were included. The dIVC at a threshold value of >23.8% provided 80% sensitivity and 87.5% specificity to predict fluid responsiveness and was statistically significant (P14% provided 95% sensitivity and 81.2% specificity to predict fluid responsiveness and was statistically significant ( Daha fazlası Daha az

Radiologic aspects of abdominal hydatidosis in children - A study of 31 cases in Turkey

Erdem, LO | Erdem, CZ | Karlioguz, K | Uner, C

Article | 2004 | CLINICAL IMAGING28 ( 3 ) , pp.196 - 200

Objective: To determine the location and radiological characteristics in children with abdominal hydatid disease (HD). Materials and methods: Thirty-one children (average age: 7.2 years) with abdominal HD were studied. The number, location, diameter and internal architecture of the cysts were assessed with abdominal ultrasonography (US) and computed tomography (CT). Density measurements and enhancement patterns were determined on CT. Results: Twenty-one children had hepatic HD. The remaining 10 children had both hepatic and extrahepatic cysts. There were splenic cysts in five children, peritoneal cysts in two children and combined s . . .plenic and peritoneal cysts in three children. The most common site of the cysts was the liver (64%), followed by the spleen (20%) and the peritoneal cavity (16%). The seven intraabdominal cysts, which were not detected by US, were 20 min or less in diameter. Conclusion: CT may demonstrate additional small intrahepatic or unsuspected extrahepatic cysts. Although rare, splenic or peritoneal hydatidosis should be included in the differential diagnosis of a cystic splenic or peritoneal lesion. Familiarity with atypical locations of HD may be helpful in making a prompt, accurate diagnosis. We think that in particular patients, especially those who had diagnostic problem and who are under surgical planning, CT should be performed additionally. (C) 2004 Elsevier Inc.

Hygroma colli cysticum: Prenatal diagnosis and prognosis

Tanriverdi, HA | Hendrik, HJ | Ertan, AK | Axt, R | Schmidt, W

Article | 2001 | AMERICAN JOURNAL OF PERINATOLOGY18 ( 8 ) , pp.415 - 420

The objective of this study is to analyze the prenatal management and prognostic factors of hygroma colli cysticum by using cytogenetic tests and sonographic morphological features. All cases with hygroma colli cysticum diagnosed and managed at our Prenatal Diagnostics Unit between January 96 and September 2000 were analyzed. Sonographic morphological features were divided in two groups; nonseptated (n = 18) and septated (n = 12) hygroma colli cysticum lesions were compared with fetal karyotype results and pregnancy outcome data. Statistical analysis was performed by Chi-square test and statistical significance was defined as p < 0. . . .05. In 5 years, 30 cases with hygroma colli cysticum were identified. Cytogenetic results were obtained from 23 (76.7%) cases (four chorionic villus sampling and 19 amniocentesis). Chromosomal abnormalities were present in 13 cases (56.5%). The most common chromosomal abnormality was Turner Syndrome (four cases, 17.4%) and Trisomy 18 (four cases, 17.4%). Pregnancy outcome data were available for 29 patients. Those fetuses with septated hygroma colli cysticum tended to have a worse fetal outcome, without statistical significance (p > 0.05), compared with the nonseptated hygroma colli cysticum cases (75 vs. 61.1%, respectively). Fetal hygroma colli cysticum, either septated or not, carries high risks of aneuploidies and adverse fetal outcome. Recommended management includes karyotyping and if parents decide to continue the pregnancy ultrasound scan at 20 to 22 weeks' gestation is necessary, for excluding associated anomalies. At birth, if the cystic hygroma persists, it should be noted that a respiratory difficulty can happen and a pediatrician should standby as a precaution Daha fazlası Daha az
