During the 10-yr study period, 16 patients were diagnosed with childhood-onset SLE. Five of them (31%) had pulmonary involvement including acute lupus pneumonitis, invasive pulmonary aspergillosis, cytomegalovirus pneumonia and pulmonary haemorrhage (in two patients). These 5 patients with lupus lung disease are presented in more detail.

In the present review we address the mechanisms of ROS production in breast cancer cells, the role of impaired oxidative status as well as the benefits of introducing oxidative stress modulators in therapeutic strategies in breast cancer. This review is focusing more on melatonin which we have been working on during the last decade. Our data, in accordance with the literature, suggest an important role for melatonin in breast cancer prevention and adjuvant therapy.

Acute and chronic renal impairment are important complications after HSCT. A prospective study was conducted to investigate the glomerular renal function in children who received allogeneic HSCT from matched related donors. Non-radiation conditioning regimens were used in all but one patient. CrCl and serial measurements of serum creatinine were evaluated prior to HSCT, within the first 100 days and one yr after. AKI was defined as at least a 1.5-fold rise in pre-HSCT serum creatinine within the first 100 days and classified as grade 1 to 3 according to the new definition criteria proposed by "AKI Network." Fifty-seven patients were enrolled in the study and 24 patients (42%) had AKI. CsA, amphotericin B, and SOS were found as risk factors for AKI. One yr after HSCT five patients (10%) had CKD and none of them required dialysis. None of the parameters were found as a predictor for CKD. We conclude that AKI is an important complication of HSCT. Careful monitoring of renal function, minimizing the use of nephrotoxic medication, prophylaxis, and effective treatment of SOS might be effective preventive measures to decrease the incidence of AKI.

The term "ES" has been widely used for describing a clinical condition consisting of skin rash, fever, and weight gain that occur during neutrophil recovery period following HSCT. In this study, the incidence, clinical features, risk factors, and outcomes of ES were evaluated in 169 children following allogeneic HSCT from full-matched related donor according to the Spitzer criteria. Seventeen patients (10.1%) presented with clinical conditions suggesting ES. In both univariate and multivariate analysis underlying malignant disease and early release of monocytes to the PB, and in univariate analysis using only CsA for GVHD prophylaxis were found to be the significant risk factors for the development of ES. Patients with ES experienced significantly higher incidence of acute and chronic GVHD and propensity toward a higher rate of TRM. OS did not differ between the patient groups. Thirteen of 17 patients received steroid therapy, and all but one patient responded to therapy. Monitoring for early detection of ES and early intervention with steroid therapy is the key for recovery. The most crucial approach for this purpose mainly is to find out and use the most useful and feasible diagnostic criteria for routine medical practice.
