Between 1983 and 1991 the Philadelphia chromosome (Ph1) was found in bone marrow and/or peripheral blood cells of 25 adult patients with acute lymphoblastic leukemia (ALL). The Ph1 as sole anomaly was seen in 13 patients, while six patients had additional structural and another six structural and numerical aberrations. Most patients (23/25) received combination chemotherapy according to the BMFT protocols 1/81, 2/84, 3/87, and 4/89. For 25 evaluable patients two early deaths, two treatment failures, two partial remissions (PR), and 19 complete remissions (CR) after phase 1 or 2 of the induction regimen were recorded. Two of these 19 patients who achieved CR are presently disease free, whereas 17 have relapsed after a median duration of remission of 9 months. Actuarial median survival for all patients was 13 months. The probability of continuous complete remission (CCR) after 39 months, as well as that of survival after 40 months, is only 6%. Our results confirm that the presence of the Ph1 is associated with a poor prognosis in adult-ALL patients. Therefore, whenever first CR is obtained and an HLA-identical donor is available, allogeneic bone marrow transplantation (BMT) should be performed at once, the more so, since transplantation in second CR seems to offer no cure. Future studies will have to show whether an intensified cytotoxic therapy can improve the prognosis of Ph1(+)-ALL.

Considering the high number of painful treatments, predictors for painful dilatations should be further clarified through standardized documentation and prospective evaluation in order to improve follow-up.

Hemochromatosis is a multisystem disorder produced by the excessive accumulation of iron in visceral organs and the musculoskeletal system. Clinically the disease may be silent, but characteristic radiological features may point to the diagnosis. The increased iron stores in the organs involved, especially in the liver and pancreas, result in an increased attenuation at unenhanced CT and an decreased signal intensity at MR imaging. Hemochromatosis arthropathy includes degenerative osteoarthritis and chondrocalcinosis. The distribution of the arthropathy is distinctive, but not unique, frequently affecting the second and third metacarpophalangeal joints of the hand.

A 33-year-old man with dyskeratosis congenita received a marrow transplant to treat severe pancytopenia. The graft was successful-, but the patient developed severe acute graft-versus-host-disease grade IV and died 51 days postgrafting. - The outcome of transplantation in dyskeratosis congenita is compared to that in Fanconi's anaemia due to the resemblance of both diseases in some aspects.

!Purpose: To determine the importance of MRI with contrast-enhanced MRA for the detection or exclusion of aberrant or obstructing renal arteries in ureteropelvic junction obstruction in children. Materials and Methods: Key word-based search in RIS database (ureteropelvic junction obstruction/ MRI) and retrospective comparison of arterial findings from preoperative contrast -enhanced MRA and intra-operative inspection. From 2007 to 2013, 19 children with ureteropelvic junction obstruction underwent contrast-enhanced MRA. Based on the results of the MRI scan and MAG3 scintigraphy, the children were referred to surgery (Anderson-Hynes-pyeloplasty). Results: An aberrant renal artery was diagnosed with MRI in 14 of 19 children, and intra-operative inspection confirmed 13 of those 14. In the remaining 5 children, no aberrant vessel could be observed in MRI and this was confirmed intra-operatively in 3 of the 5 cases, while in the remaining 2, an aberrant vessel was found. Of the 14 children with aberrant vessels, 12 underwent surgery due to assumed ureteral obstruction, which was confirmed by surgery in 11 cases. In one case, an aberrant artery was found intra-operatively, but obstruction could not be confirmed. In one of the 14 children, the vessel was found in MRI, but its obstructing character was negated via MRA, which was confirmed intra-operatively. In the diagnosis of aberrant and obstructing renal arteries, contrast-enhanced MRA presents 85 % sensitivity and 80 % specificity, with a positive predictive value of 0.8. Conclusion: MRI with contrast-enhanced MRA is suitable to detect aberrant and obstructing renal arteries. An obstructive effect of the aberrant vessel is to be assumed if the vessel has a close relationship to the ureteropelvic junction and if it is linearly stretched.
