Clinical TrialPreliminary results of primary chemotherapy in retinoblastoma.
Eye retention rates after external beam therapy for advanced retinoblastoma are close to 90% with very few ocular side effects like radiation retinopathy or radiation induced optic neuropathy. Late complications, however, comprise a sixfold increase of secondary non-ocular cancers like soft tissue sarcomas demanding alternative treatment options in the management of advanced retinoblastoma. ⋯ Based on the results of this study and on the results published by others primary chemotherapy may result in the same eye retention rate as conventional external beam therapy avoiding the unacceptable high rate of secondary non-ocular cancers in the latter. A prospective study to be undertaken by the GPOH (Gesellschaft für Pädiatrische Onkologie und Hämatologie) and the RG (Retinologische Gesellschaft) is planned to further evaluate this new and promising approach.

[Simultaneous measurements of end-expiratory and transcutaneous carbon dioxide partial pressure in ventilated premature and newborn infants].
The aim of the present trial was to study the relationship between end-tidal pCO2 (p(et)CO2) and transcutaneous pCO2 (ptcCO2) after in-vivo calibration in ventilated newborns. ⋯ Capnographic determination of P(et)CO2 provides informations about alveolar ventilation-perfusion-disturbances. Capnography enables the on-line control of end-tidal pCO2 in neonates with respiratory failure. It cannot replace transcutaneous pCO2 measurements or blood gas analysis but it can reduce its frequency in clinically stable patients. The analysis of the capnogram can be used to optimise artificial ventilation. A quantitative evaluation of the capnogram by calculation of Murányi's-CO2-Index was possible only in 28% of the ventilated newborns which limits its value in such patients.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial[5-day therapy of bacterial pharyngitis and tonsillitis with cefixime. Comparison with 10 day treatment with penicillin V. Cefixime Study Group].
160 children aged 1 to 12 years with clinical diagnosis of bacterial pharyngitis and/or tonsillitis were treated either with cefixime ready-to-use-suspension or penicillin V in an open, controlled and randomized multicenter study. Before treatment a rapid antigen detection test was accomplished and throat swabs were taken. After randomization, the children were either treated for 5 days with 8 mg cefixime/kg bodyweight ready-to-use suspension once daily or with 20,000 I. ⋯ Both regimes were safe. Mild to moderate adverse events at least possibly related to the study medication were seen in only 4 children treated with cefixime and in 5 treated with penicillin. A 5 day treatment of bacterial pharyngitis and tonsillitis with cefixime was as effective as a ten day treatment with penicillin V.

[Prognosis of children with chronic myeloid leukemia: a retrospective analysis of 75 patients].
As the probability of survival of patients with chronic myelocytic leukemia (CML) gradually decreases over a period of 10 years, long-term follow-up is mandatory. Between 1977 and 1994, 68 children and adolescents between 1.0 and 18 years of age with CML in chronic phase and 7 presenting with blast crisis at diagnosis were reported to the study center in Münster. The Philadelphia-chromosome and/or BCR/ABL rearrangement could be detected in 66 children. The 4 Philadelphia-negative patients and 5 patients without karyotyping fulfilled the morphological criteria of CML. Clinical symptoms and hematological findings at presentations were similar to adult patients. ⋯ Our data confirm the unfavourable outcome of CML in pediatric patients if treated with chemotherapy alone. With early BMT high cure rates can be achieved. If transplant-related mortality which in our patient group was 21% (8/39) can be reduced, even a higher cure rate appear realistic for the future.

[Extra-cerebral intracranial fluid collections in childhood: differentiation between benign subarachnoid space enlargement and subdural effusion using color-coded duplex ultrasound].
Extracerebral fluid collections in infancy are a common diagnostic problem, because by noninvasive imaging studies (including cranial ultrasonography, CT and NMR), no definite differentiation between two distinct pathological conditions can be found until today: An enlargement of the subarachnoid spaces in children with macrocephaly is a frequent observation of mostly unknown etiology but is known to be associated with a good prognosis. If surgery is necessary in these patients, ventricular shunting is required. On the other hand subdural effusions are often of traumatic origin and require frequently neurosurgical intervention (subdural shunting). Most reports on extracerebral fluid collections in infancy have not differentiated between both pathological conditions and therefore reveal confusing results. Recent studies using magnetic resonance imaging have shown that vascular flow phenomena in the arachnoid space can be used to a reliable diagnosis, whereas previous noninvasive neuroimaging attempts including high resolution computerized tomography (CT) have been useless. ⋯ Out of these observations we conclude that high resolution ultrasound and colour-Doppler sonography are able to reliably differentiate between a subdural and a subarachnoid fluid collection. An NMR investigation with its higher risks (sedation, anesthesia) focused on this target only seems therefore to be not necessary in these patients.
