Unlabelled: We report on four children with heparin-induced thrombocytopenia type II. In three patients, therapy with unfractionated heparin was associated with development of cardiac thrombi or with thrombosis progression up to the inferior vena cava or with aggravation of peripheral arterial occlusion. In the fourth child, the disease was recognized early on, and no complication occurred. Heparin-induced thrombocytopenia type II was confirmed by heparin-induced platelet activation assay and/or heparin/platelet factor 4-ELISA. Concomitant elevated antiphospholipid antibodies were seen in all patients. Danaparoid sodium applied at a dosage of between 1.2 and 7.1 U/kg/h stopped the disease progression in each patient. Three children had a clinical recovery with partial recanalization, but for the child with peripheral arterial occlusion disease, amputation of some of the toes became necessary.Conclusion: Our data indicate that heparin-induced thrombocytopenia type II is a potential life-threatening disease in children and danaparoid sodium is beneficial in this age group.

We report a boy who developed a vertebral stroke immediately after an appendectomy. Basilar impression was diagnosed eight years after this event when skull roentgenograms revealed basilar impression with high standing tip of the odontoid. We speculate that muscle relaxation and cervical hyperextension during intubation in the presence of basilar impression resulted in vertebral artery dissection and stroke. We suggest that patients with vertebral stroke and no obvious risk factors should be evaluated for the presence of malformations of the craniovertebral junction to be able to take precautions against excessive neck movement during intubation.

Background: Tick-borne encephalitis in children appears to be more benign than in adults and shows also a more favourable outcome. Only some authors report of sequelae like paralysis, paresis or seizures and behavioural abnormalities. The aim was to describe the clinical features of tick-borne encephalitis in children with special attention to sequelae and to review the literature., Methods: Retrospective review of all charts of children with serologically confirmed tick-borne encephalitis hospitalised in Styria between 1981 and 2005., Results: One hundred sixteen children were diagnosed with tick-borne encephalitis. Ninety-two children (79.3%) developed meningitis and 24 (20.7%) meningoencephalitis. Eleven patients with meningoencephalitis showed somnolence, 5 confusion, 5 tremors, 2 facial palsy, 1 ataxia, 1 epileptic seizure and 1 hemi paresis. Seven patients had to be admitted to the intensive care unit. Two children (1.7%) developed long time neurological sequelae: one epileptic seizure with requirement of antiepileptic therapy and one left-sided hemi paresis. One hundred twelve children had been not and 3 incompletely vaccinated against tick-borne encephalitis. Only one child had been fully vaccinated according to the Austrian vaccination schedule., Conclusion: Our study provides further evidence that tick-borne encephalitis in children has a substantial morbidity and in single cases severe long-time neurological sequelae are observed.
