Different anatomical sites of the foreign body injury with 2999 children during 2012-2016.

PURPOSE: This study aimed to analyze the clinical characteristic of different foreign body injuries in children and offer the preventions. METHODS: A retrospective study and the demographic information, injury causes, foreign body injury types and other clinical factors were recorded and analyzed. RESULTS: Of the 2999 patients, 1877 (62.6%) were boys and 1122 (37.4%) were girls. The majority (72.8%, n = 2184) of the injuries were found in 1-3 years old children. The most common anatomical site was the respiratory tract (73.4%, n = 2201) followed by the digestive tract (18.6%, n = 558), the genitourinary tract (1.93%, n = 58) and other sites (6.07%, n = 182). There were 60.4% of the in-patients from rural areas and 53.2% of the patients without medical insurance, the rate of cost by medical insurance increased with age. The medians of length of hospital stay and hospitalization cost were four days and 4767.3 CNY respectively. Most of the patients had surgical treatment (90.6%, n = 2717) and 64.9% of them had the complications (n = 1946). The cure rates of the all foreign body injuries types were above 90%, especially in genitourinary tract (98.3%). CONCLUSION: Different types of the foreign body injuries had dissimilar clinical characteristics. The effective prevention and control measures should be taken according to the variety of high-risk population, incidence season and foreign body injury types.

[Analysis of viral etiology of severe pneumonia in infants and young children in Chongqing area].

OBJECTIVE: To investigate the prevalence of viral infections and putative association of viral infection with illness severity in young children with severe lower respiratory tract infection (LRTI) in Chongqing. METHOD: Respiratory secretion specimens were collected from 119 hospitalized patients with severe pneumonia from December 2006 to March 2008.After being processed, the samples were detected for respiratory viruses including respiratory syncytial virus (RSV), adenovirus (ADV), human metapneumovirus (hMPV), human bocavirus (HBoV), parainfluenza virus 1, 2, 3 (PIV 1, 2, 3), influenza virus A and B (IVA and IVB) either by PCR or RT-PCR. Clinical data were analyzed along with virological data by using appropriate statistical methods. RESULT: Viral pathogens were identified in specimens of 86 (72.3%) cases, among which RSV was detected in 49 (41.2%) patients. More than one virus was detected in 23 individual (26.7%) samples, of which 19 were dual positive for RSV and another virus. Bacterial cultures were performed for 69 patients. Both bacterial and viral pathogens were identified in 53 (76.8%) patients. Bacterial and viral coinfection was demonstrated in samples from 41 (59.4%) cases. CONCLUSION: Viral pathogens are the main etiology of severe pneumonia in young children in Chongqing area during the study period. RSV was the most frequent viral pathogens, followed by ADV and hMPV. Coinfection with respiratory common viruses was relatively common, though co-infection with viruses did not appear to aggravate the patients' condition.
