In a practical setting, 4 different prophylactic methods were compared with regard to their effects on the incidence of decalcification during orthodontic fixed appliance therapy and on the frequency of premature debonding resulting from imminent or already manifest decalcification. This study showed that the use of a system in which selection and care were(More)
The morphology of approximal enamel that has been stripped for therapeutic reasons was evaluated under the scanning electron microscope (SEM) twelve weeks and one year after treatment. In part one of the study the teeth were extracted before evaluation, in the second part replica were taken. For comparative reasons the morphology of the natural approximal(More)
In an in-vitro study the abrasive qualities of different orthodontic finishing strips were evaluated on the enamel surfaces of human teeth by means of a scanning electron microscope. As a result we can state that even the use of the finest finishing strip cannot eliminate the deep furrows that resulted from prior abrasion with a strip that is more coarse.(More)
OBJECTIVE To evaluate the hemodynamic effects of tolazoline and prostacyclin in infants with pulmonary vasospasm after cardiac surgery. DESIGN Prospective cohort study. SETTING Pediatric ICU.

A longitudinal clinical-axiographic study including 10 patients who had undergone surgical mandibular advancement to correct a dental and skeletal Class II anomaly, produced evidence of correlations between alterations of acoustic symptoms and of mandibular mobility. In 7 of 11 movements, where TMJ-sounds disappeared, post-operative mandibular mobility was(More)
Recombinant human (rh) granulocyte-macrophage colony-stimulating factor (GM-SCF) is currently being tested in clinical trials for the treatment of acute myeloid leukemias with two main intentions: reduction of neutropenia and recruitment of leukemic blasts into cell cycle to enhance cytarabine (ara-C) mediated cytotoxicity. We report a case of a fatal(More)
We retrospectively evaluated the outcome from cardiopulmonary resuscitation (CPR) in 149 children of all age groups. Only 7 children experienced ventricular fibrillation. 47 children (31.5%) died immediately. Further 47 children died within 24 hours of their arrest, 24 (16.1%) survived longer than 24 hours after CPR but not until discharge. Only 31 children(More)
A prospective study including 63 adult Class II and Class III patients was carried out in order to examine short- and long-term effects of four different treatment methods on mandibular mobility. The patients were treated either (Group A, control-group) orthodontically alone or (Group B) by a LeFort I-osteotomy, a (Group C) mandibular advancement or (Group(More)
Recombinant human tissue-type plasminogen activator (rt-PA) was successfully given via central vein to a 1.7 year old child with angiographically documented septic vena cava superior thrombosis Thrombolytic therapy with rt-PA was started with 0.2 mg/kg as a slow bolus injection followed by an infusion of 0.8 mg/kg over 60 min. rt-PA was applicated 12 hours(More)
