    Notes: Abstract Cytogenetic analysis of a human embryonal rhabdomyosarcoma revealed a near-diploid karyotype with structural chromosome aberrations not involving the typical rearrangements of rhabdomyosarcomas, plus a large number of double minutes. Comparative genomic hybridization revealed a previously undescribed site of DNA amplification on the short arm of chromosome 1 (band 1p32-33).

    Notes: Abstract In the present article, we report, for the first time, a prenatal diagnosis of a congenital mesoblastic nephroma in combination with a post-partum hyperreninemia with hypertension. A newborn was delivered at 35 weeks gestation who had an intrauterine diagnosis of a renal mass as early as 32 weeks gestational age by ultrasound examination. Tumor nephrectomy was performed on day 11 after delivery when an increase in hypertension was observed in the newborn.

    Notes: The incidence of a drug-induced pancreatitis is rare and so far more than 85 different drugs have been reported to have induced pancreatitis. Some case reports consider a relationship between propofol and acute pancreatitis. However, in these cases a number of different drugs were coadministered, thus preventing a clear causal link being established. We report a case of a drug-induced acute pancreatitis that was most likely triggered by a single dosage of propofol. It occurred in a young girl who underwent elective magnetic resonance imaging. She developed pancreatitis within hours after exposure to propofol. Other possible triggers, e.g. gallstones or infection were ruled out. Physicians should consider pancreatitis as a potentially life-threatening adverse event associated with propofol sedation, which is nowadays extensively used.

    Notes: Abstract Objectives. To describe the imaging features of nephroblastomatosis with US, CT and MR, to point out characteristics of differentiation between nephrogenic rests (NR) and Wilms' tumour (WT) and to determine the most appropriate imaging modality. Materials and methods. We reviewed the US, CT and MR images of 29 cases of histopathologically confirmed nephroblastomatosis sent to our department for reference evaluation (German nephroblastoma study). The series included 17 kidneys with NR, 6 kidneys with WT and 32 kidneys with both NR and WT. Results. NR presented as multinodular, peripheral, cortical lesions, the diffuse form of distribution being less common. Foci were homogeneous and of low echogenicity, density or signal intensity. The lesions were most clearly depicted with contrast-enhanced CT and T1-weighted (T1-W) MR images. Lesions smaller than 1 cm were rarely identified by US. The most reliable criterion to differentiate NR from WT was their homogeneity. Conclusions. Contrast-enhanced CT and T1-W MR images are of similar potential and superior to US in the diagnosis of nephroblastomatosis. Due to the significant radiation dose of serial CT, MR imaging should be the method of choice wherever it is available. The cost-effectiveness and availability of US makes it ideal for serial follow-up of known lesions.

    Notes: Abstract A case is presented of a 3-year-old boy with a mesenchymal chondrosarcoma extending from the 1st to the 5th lumbar vertebra. This is the youngest case of a mesenchymal chondrasarcoma located outside the skeleton or in the C.N.S. After assumed total excision with subsequent radiotherapy and chemotherapy, local tumor recurrence and (later) systemic metastases were detected. Standard therapy should include radical excision because of the high incidence of local recurrence and subsequent radiotherapy because of the expected high incidence of tumor cells in the CSF. The value of chemotherapy cannot be assessed, as it has been applied in only one other case found in the literature.

    Notes: Abstract A 17 year old patient suffering from thalassemia, who had been dependent on transfusions since the age of three, showed an increasing incomplete sensory and motor transverse cord lesion below T-10. The causes were found to be multiple epidural erythropoietic foci, confirmed by myelography, CT, and biopsy. The lesions were located in the thoracic, lumbar, and sacral regions. Complete remission of the neurological symptoms was achieved by an immediate hypertransfusion regimen and subsequent local radiation therapy of the neuroaxis. Thirty-six cases of thalassemia and spinal space occupying lesions have been reported in the literature. The therapeutic results of these are presented and compared with our findings.
