The Coexistence of Atherosclerotic Intracranial Arterial Stenosis With Intracranial Aneurysms

Atherosclerotic Intracranial Arterial Stenosis With Intracranial Aneurysms

Atherosclerotic intracranial arterial(ICA) stenosis and intracranial aneurysms are the common causes of ischemic stroke and hemorrhagic stroke, respectively. Investigators aimed to assess the prevalence of cerebral aneurysms in patients with atherosclerotic intracranial arterial stenosis.

Microbiological Examination of Children Operated for Congenital Lacrimal Stenosis

Congenital Lacrimal Stenosis

Children with congenital lacrimal stenosis are treated by probing and intubation of the lacrimal drainage system. Hypothesis: Microbiological findings at the time of insertion and removal of the silicon intubation have an influence on the clinical outcome and success rate of the surgical treatment. Microbiological specimens are taken from conjunctiva and nasal mucosa during the two procedures under general anaesthesia and from the silicon tube after removal and examined for bacterial contamination.
