Background: Contrary to adults, primary and metastatic involvement of CNS is a rare condition in pediatric malignant tumors. With CNS involvement the prognosis will be poor and practical treatment modalities will decline so new approaches must be reviewed. The aim of this study was to find out the incidence of CNS involvement in different childhood malignancies. Also the survival analysis w...
This paper presents a new approach for region-based video mosaicing, treating moving objects separately from the background, and with improved ghost-like noise elimination. The mosaic images show the moving objects superimposed over a stationary background. Conventional technologies can reduce the ghost-like noise that occurs from moving objects by using temporal median filtering, but its effic...
Chronic nasal disease is a common problem in dogs. To determine the aetiology, a retrospective study in 75 dogs with persistent and chronic nasal disease was done. All dogs were evaluated by means of survey nasal radiographs, antegrade and retrograde rhinoscopy, bacterial and fungal cultures, and histopathology. A definitive diagnosis was made in 74/75 cases (98.6%). Nasal neoplasia was the mos...
Background: Hemorrhagic choroidal neovascularization in patients with age-related macular degeneration (AMD) is a serious complication that if left untreated may cause severe consequences in patients’ visual acuity. Although there is not a standard treatment for this condition, intravitreal tissue plasminogen activator (t-PA) with gas is a classic and highly enthusiastic approach. Using this tr...
Background: Transcription factors (TFs) play a key role in the development, therapy, and relapse of B-cell malignancies, such as B-cell precursor acute lymphoblastic leukemia (BCP-ALL). Given the essential function of Forkhead box protein P1 (FOXP1) transcription factor in the early development of B-cells, this study was designed to evaluate FOXP1 gene expression levels in pediatric BCP-ALL pat...
OBJECTIVE To evaluate whether circulating endothelin, a peptide that is thought to play a part in mediating vascular tone, might be high in pulmonary hypertensive congenital heart disease. DESIGN A prospective study with a radioimmunoassay technique to estimate urinary and plasma endothelin concentrations. SETTING A supraregional referral centre for patients with congenital heart disease. ...
