At the Department of Neurosurgery, Hradec Králové, 454 children (aged under 18 years) were operated on for posterior cranial fossa lesions in a period of 49 years (1948–1996). The majority (402) had tumours: cerebellar astrocytomas 149 (37.1%), medulloblastomas 139 (34.6%), brain stem gliomas 46 (11.4%), ependymomas 28 (7.0%), and others 40 (9.9%).(More)
Different collagenic tissues, such as allogeneic fascia lata, dura mater and xenogeneic pericardium preserved by deep freezing or freeze-drying and packed in National Blood Service jars have been used with good clinical results in duraplasties performed at the Department of Neurosurgery, University Hospital at Hradec Králové since 1956. In 1986 a new(More)
A series of 314 posterior fossa duraplasties in children were performed at the Department of Neurosurgery, Hradec Králové, over the past 33 years. Computed tomographic (CT) imaging was used to compare the healing of various kinds of collagenic dural substitutes — allogeneic fascia lata, allogeneic dura mater and xenogeneic pericardium. Early (8 days to 3(More)
A 5-year experience with the glutaraldehyde-stabilized freeze-dried radiation-sterilized calf pericardium used as a dural substitute is reported. The structure of pericardium xenograft is compared with other collagenous materials used for duraplasty (allogeneic fascia lata and dura mater) by light and electron microscopy. The special neurosurgical(More)
The authors report on their 2 1/2-year clinical experience using a dural substitute, ovine pericardium, stabilized with 0.3% glutaraldehyde, flat freeze-dried, and sterilized with gamma-irradiation. Packaging of the ovine pericardium in double-plastic transparent bags allows simple storage in operating rooms and the opportunity for the surgeon to choose an(More)
Group of 152 patients (investigated before autologous transplantation) and 35 healthy donors for allogeneic transplantation was examined for the risk of infection transmission that can be associated with the infusion of cryopreserved peripheral blood progenitor cells to the patient and/or cross-contamination of stored grafts. No laboratory signs of active(More)
PURPOSE To evaluate expandable stents healed into vein wall as autologous vein stent-grafts for endoluminal grafting. MATERIALS AND METHODS Balloon expandable stents were placed into external jugular veins of eight dogs. Stent and vein patency was followed by ultrasonography. Five weeks after stent placement, jugular veins with endothelialized stent were(More)
The authors describe cases of external lumbar CSF drainage with a regulated flow inserted lumbally or in the pseudomeningocele in children. During flow regulation during operation they were guided by the finding in the surgical field, during therapeutic use (in the course of 1-8 days) by setting the CSF output at 15 ml/hour. Drainage was used in extradural(More)
Čermák P., Landfeld A., Měřička P., Houška M. (2009): Enterococcus faecium growth model. Czech J. Food Sci., 27: 361–371. Enterococci are bacteria commonly found in humans. However, these bacteria can cause severe infections in susceptible individuals. The strains of Enterococcus faecium have demonstrated an increasing resistance to antibiotics, which is(More)
In a group of 71 patients and 22 donors the danger of infection transmission by infusion of cryopreserved peripheral blood progenitor cells to the patient and/or cross contamination of stored grafts was evaluated. No laboratory signs of active infection were found in 15 donors (13 related, 2 unrelated; 68 %) and in 55 patients (77 %). Active infection by(More)
