Characteristics and outcome of synchronous bilateral Wilms tumour in the SIOP WT 2001 Study: Report from the SIOP Renal Tumour Study Group (SIOP-RTSG).

Background: Among patients with nephroblastoma, those with bilateral disease are a unique population where maximising tumour control must be balanced with preserving renal parenchyma.

Methods: The SIOP 2001 protocol recommended surgery after neoadjuvant cycle(s) of Dactinomycin and Vincristine (AV) with response-adapted intensification, if needed. Adjuvant treatment was given based on the lesion with the worst histology.

Near-Adult Heights and Adult Height Predictions Using Automated and Conventional Greulich-Pyle Bone Age Determinations in Children with Chronic Endocrine Diseases.

Objectives: To validate adult height predictions (BX) using automated and Greulich-Pyle bone age determinations in children with chronic endocrine diseases.

Methods: Heights and near-adult heights were measured in 82 patients (48 females) with chronic endocrinopathies at the age of 10.45 ± 2.

Transient elastography correlated to four different histological fibrosis scores in children with liver disease.

Currently, liver histology is the gold standard for the detection of liver fibrosis. In recent years, new methods such as transient elastography (TE) have been introduced into clinical practice, which allow a non-invasive assessment of liver fibrosis. The aim of the present study was to investigate the predictive value of TE for higher grade fibrosis and whether there is any relevance which histologic score is used for matching.

ARFI shear-wave elastography with simulation of acute urinary tract obstruction in an ex vivo porcine kidney model.

Methods: A total of 20 heparinized pig kidneys were investigated at 10 intrapelvic hydrostatic pressure steps (0-90 mmHg). SWE (ARFI; Virtual TouchTM IQ, Siemens) measurements were taken at three different measuring regions and in two measuring sequences using a linear ultrasonography probe (9L4, Siemens). Median values of 10 shear-wave speed (SWS) measurements were calculated for each pressure step.

Limitations and opportunities of non-invasive liver stiffness measurement in children.

Changes in liver structure are an important issue in chronic hepatopathies. Until the end of the 20 century, these changes could only be determined by histological analyses of a liver specimen obtained biopsy. The well-known limitations of this technique (.

Assessment of aortic morphology and compliance in children and adolescents with Ullrich-Turner syndrome (UTS) using magnetic resonance imaging (MRI).

Aim: The aim of this study was to evaluate the morphology and elastic properties of the aorta in children and adolescents with Ullrich-Turner syndrome (UTS) treated with growth hormone, by using magnetic resonance imaging (MRI).

Methods: Thirty-seven conscious UTS patients were examined using a 1.5-T whole-body MRI.

Feasibility study and control values of transient elastography in healthy children.

Transient elastography (TE) is a new technique for the non-invasive assessment of liver fibrosis. The degree of fibrosis is equivalent to the liver stiffness measured in kilopascal (kPa). It is frequently used in adult patients with a mean normal stiffness of 4.

Tumor biology influences the prognosis of nephroblastoma patients with primary pulmonary metastases: results from SIOP 93-01/GPOH and SIOP 2001/GPOH.

Objective: To analyze the outcome of Wilms' tumor patients with primary lung metastases.

Summary Background Data: Radiotherapy and/or surgery are used for local control of primary pulmonary Wilms' tumor metastases. A widely accepted treatment standardization is still lacking.

A new pediatric liver transplantation program in Southern Germany. The Heidelberg experience.

pLTx is a highly complex procedure. It can only be performed safely by experienced teams. Starting a new pLTx program in a country with established centers must therefore avoid a learning curve.

Sexual pseudo-precocity caused by a somatic activating mutation of the LH receptor preceding true sexual precocity.

Aim: We describe the clinical features of a 6-year-old boy with sexual precocity caused by a somatic activating mutation of the luteinizing hormone (LH) receptor gene preceding gonadotropin-releasing hormone (GnRH)-dependent sexual precocity.

Study Design: Genomic DNA was extracted from the right testis and from the peripheral leukocytes followed by DNA amplification and sequencing of the LH receptor gene. We described the clinical characteristics including anthropometric parameters, bone age, and endocrine evaluation when the boy presented with sexual precocity.

Evolution of large-vessel arteriopathy in paediatric patients with chronic kidney disease.

Unlabelled: This observational study was designed to verify the hypothesis that the treatment modality significantly affects the evolution of CKD-associated arteriopathy.

Patients: Paediatric patients (mean age 13.8 +/- 4.

Current radiological management of intussusception in children.

Intussusception is the most common abdominal emergency situation in infants and small children. There has been great progress in diagnostic and therapeutic management of intussusception. Ultrasound (US) has been shown to be the first-choice imaging technique in diagnosing intussusception for reasons of high accuracy, simultaneous exclusion of differential diagnoses, and disclosure of additional pathologies.

Mesoblastic nephroma--a report from the Gesellschaft fur Pädiatrische Onkologie und Hämatologie (GPOH).

Background: Surgery alone is the appropriate first-line treatment for patients with mesoblastic nephroma (MN). Nevertheless, there are reports of local recurrences and metastasis, especially in the cellular subtype. The authors evaluated the outcome of patients with MN who were enrolled in either the International Society of Pediatric Oncology (SIOP) 93-01/GPOH or the SIOP 2001/GPOH Nephroblastoma Study and Trial.
