Results: Of 1771 neonatal reports, there were 18 deaths in 8 boys and 9 girls (1 patient unclassified). The mean age at vaccination for these 18 cases was 12 days (range, 1-27 days); median time from vaccination to onset of symptoms was 2 days (range, 0-20 days); and median time from symptoms to death was 0 days (range, 0-15 days). The mean birth weight of the neonates (n = 15) was 3034 g (rang...
Background and Objectives: Tuberculosis is the most common cause of death among single-factor infectious diseases and is the tenth cause of death among all diseases in the world. The disease is spread mainly from an infected person through close contact with other people living in one place. The aim of this study was to investigate the relationship between the spatial correlation structure and ...
A mean residence time (MRT) is an important pharmacokinetic parameter. To the author's knowledge, however, a physiologically based structure of MRT (thereafter MRT structure) has not been published so far. Primarily this is because MRT structures cannot be identified by traditional pharmacokinetic methods used for the determination of MRT. Therefore, tools from the theory of linear dynamic syst...
Intercomparisons of hillslopes and catchments in different hydrogeomorphic settings are rare. Those comparison studies that have been completed have focused largely on bulk outflow and chemistry. Here, we present a new functional intercomparison of two well studied hillslopes: one in New Zealand at Maimai and one in Japan at Fudoji. Slope angle, slope length, soil depth, climate and vegetation ...
In Buchwalder et al. [3] we have revisited Mack’s [7] and Murphy’s [9] estimates for the mean square error of prediction (MSEP) of the chain ladder claims reserving method. This was done using a time series model for the chain ladder method. In this paper we extend the time series model to determine an estimate for the MSEP of a portfolio of N correlated run-off triangles. This estimate differs...
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...
Background and purpose: Lung cancer is the third cause of death and amongst the five common cancers in Iran. The aim of this study was to analyze the survival rate of patients with lung cancer and identifying the variables influencing their survival. Materials and methods: In a retrospective cohort study, the data was extracted from the medical records of 259 patients with lung cancer who had ...
