Human bocavirus (hBoV) was first discovered in respiratory samples from children in 2005, and has been classified in the Parvoviridae family. hBoV has also been detected in children with acute gastroenteritis. This study was performed to analyze the frequency and phylogeny of hBoV in the respiratory and stool samples of children with acute respiratory tract illnesses and gastroenteritis during the time period beginning 2006 and ending 2008, at the Virology Research Centre, Masih Daneshvari Hospital, NRITLD, Tehran, Iran. Respiratory and stool samples were screened for hBoV by nested polymerase chain reaction with primers from the NS-1 gene. Nine out of 133 respiratory samples (6.8%) and 6 out of 47 stool samples (12.8%) were positive for hBoV. Ten positive samples (7 respiratory and 3 stool samples) were subjected to phylogenetic analysis by sequencing a fragment of the VP1/VP2 gene junction. The results showed a high similarity among isolates (>or=99%). It was found that hBoV isolates can be divided into 3 genetic groups.

Background: Cystic fibrosis is a complex progressive disease which assessing its progression and severity is essential. For this purpose there are scoring systems available to evaluate the disease severity. Objectives:The aim of the present study was to determine the clinical status of CF patients using shwachman score system in the pediatric pulmonary ward of Masih Daneshvari Hospital. Patients and Methods:A cross-sectional study was conducted to evaluate the clinical status with shwachman score system. 23 patients ranging from 5 to23 years were enrolled in this study. All data was extracted objectively from Shwachman-Kulczycki scoring system. Results: The overall mean Shwachman-Kulczycki score was 53.48 ± 13.8. Total scores of < 40 (severe), 41-55, 56-70, and 71-85 were detected in 1.7%, 39.1%, 30.4% and 8.7% of patients respectively. None of the patients were categorized in the excellent range. We found no statistically significant correlation between mortality rate and clinical score (P = 0.136). However, the results showed a statistically significant correlation between mortality rate and Shwachman score, (P = 0.02). Conclusions: Shwachman-Kulczycki score is an easily applied scoring system which can reflect the clinical status of patients objectively. However, concurrent use of other evaluating tools such as pulmonary function test (PFT) and Computed tomography scoring systems provide a more robust monitoring and a reliable evaluation tool.
