ABSTRACT
Background: Acute respiratory tract infections (ARI) are the leading cause of death in children in the world (11.9 million per year) with the greatest number of deaths occurring in developing countries like India. We compared respiratory severity scoring system RSS (Respiratory Severity Score) with Modified TAL, so that we can find out which of the above scores are better and whether they can be implemented to assess pediatric ARI patients.Methods: This prospective observational study was conducted in Pediatrics wards, Shri Vasantrao Naik Government Medical College, Yavatmal, Maharashtra and data were collected from 290 children below 12 years of age by purposive sampling. All the children presenting with respiratory symptoms were subjected to these scoring system (RSS AND MODIFIED TAL) at the time of admission and were classified based on the scores obtained in respective scoring system. Data was analysed using frequencies, percentages and contingency tables and comparison was made between the above scoring systems to find which one is better applicable in pediatric ARI patient.Results: Incidence of pediatric patients presenting with only respiratory tract infections who are admitted in ward was 25.15 %, with more incidence being reported in children below 12 months (49.31%), males more affected. For both the ARI scoring systems (RSS and MOD TAL) as the severity increased so is the number of patients requiring oxygen and duration of hospitalization increased significantly (p<0.05), with RSS having stronger association.Conclusions: Both the scoring systems predicted that on admission if the score is more than chances of requirement of oxygen is more and also duration of hospitalization is more, with RSS being better predictor.
ABSTRACT
Objective To investigate the epidemiology of respiratory viruses in children from Wuxi area.Methods A total of 2 747 cases of children diagnosed with acute respiratory infection in Wuxi during 2011 —2014 were collected.Reverse transcription-polymerase chain reaction was used to detect nine kinds of respiratory viruses,including influenza virus A (Flu A),influenza virus B (Flu B),parainfluenza virus (PIV)Ⅰ-Ⅳ,adenovirus (ADV),respiratory sycytial virus (RSV),human metaneumovirus (hMPV), human bocavirus (HBov),human coronaviruses (hCov)and human rhinovirus (HRV).The categorical data were compared using chi square test.Results A total of 856 among the 2 747 samples were tested positive for respiratory virus nucleic acid,with the positive rate of 31 .16%.The viral distribution was uneven in different seasons,and the infection peaked in winter and spring.The virus detection rate was highest in age 1 to 2 year group (up to 40.18%),and followed by age 6 to 12 year group (32.63%).Flu A virus was the most frequently detected virus,accounting for 7.54% (207/2 747);followed by PIV, accounting for 6.95 % (191/2 747);and Flu B accounted for 4.22%(116/2 747).There were 84 cases of mixed infection of two or more kinds of respiratory viruses,with positive rate of 3.06% (84/2 747 ). Conclusions Our study suggests that Flu A is the most common pathogen in children with acute respiratory infections in Wuxi area during 2011 —2014;virus detection rate is highest in age 1 to 2 year group;and parainfluenza virus is almost detected throughout the year,while the rest of respiratory viruses are commonly seen in winter and spring.
ABSTRACT
Background: Globally, each year malnutrition is implicated in about 40% of the 11 million deaths of under-five children in developing countries. Under nutrition is still the major problem in our country especially in underserved areas such as urban slums and rural areas. So we undertook this study to assess the factors associated with malnutrition and risk of infections among malnourished children. Methods: Study design: Analytical cross-sectional study. Duration: January 2013 - December 2013 (1 year). 182 malnourished children admitted to department of paediatrics during the study period. Prestructured-pre tested closed ended questionnaire was used to collect the data. The parents were interviewed; case sheets and other records were searched to get the necessary information. Results: The study was conducted among 182 under nourished children who admitted to department of paediatrics, in the calendar of 2013. Out of 182 children, 80 (43.96%) were boys and 102 (56.04%) were girls. More than 2/3rd (68.6%) under nourished children were in the age group of 0-3 years. Most common co-morbidity found was respiratory tract infection (44%) followed by acute gastro enteritis (22.5%) and fever (Pyrexia of unknown origine-22.5%). Conclusion: Children of relatively younger age, from rural areas and girls are the common victims of malnutrition. Respiratory tract infections and acute gastro-enteritis were the common co-morbid conditions found among malnourished children. Nutrition education has to be imparted to the people regarding consumption of cost effective nutritious diet (Emphasize it in Village health and Nutrition day).
ABSTRACT
Objective To investigate the epidemiological features of respiratory syncytial virus (RSV) A and B in hospitalized children with acute respiratory tract infections(ARTIs) and to analyze the genetic characteristics of G protein gene of RSV in Chongqing area, especially for BA strains. Methods Nasopharyngeal secretions collected from 508 hospitalized children with ARTls from April, 2008 to March, 2009 were screened for RSV using RT-PCR. Full length G protein gene was amplified by RT-PCR from 10 RSV subtype A and 29 RSV subtype B strains. Results Out of the total 508 specimens, 126 (24.8%) were revealed positive for RSV. RSV subtype A and B viruses accounted for 34.1% and 63.5% of the total positive specimens, respectively. The remaining 2.4% of the specimens were positive for both subtype A and B. At the nucleotide level, identities between the 10 subtype A virus G genes and that of the prototype strain A2 were 91.4% -92.0%, indicating genotype GA2. Identities of the 29 subtype B virus G genes and that of the CH18537 strain were 92.0%-93.0%. Nineteen out of 29 RSV subtype B isolates contained highly repeated 60 nucleotides insertion in G protein gene, namely BA strain. As compared to the prototypes, the RSV G protein gene included nucleotide deletion, insertion, substitutions, especially in the carboxy-terminal third of the G gene. Condnsion RSV has been the major cause of acute respiratory tract infections in children in Chongqing area. Subtype B strains, especially BA strains, were predominant during the study peried. Whether the predominated circulation of BA strain is resulted from enhanced attachment function of G protein remains unknown.

ABSTRACT
An enquiry was conducted in Thua Thien Hue provinces on 400 children of under 5 years old, their 159 subjects were diagnosed as acute pulmonary infection according to WHO criteria. In comparing with other diseases and conditions in the same studied time, the incidence of acute pulmonary infection 39.75%, surpassing other condition 47.50% of cases reach the frequency of 4-6 periods each year, 36.39% 6 periods each year. Risk factors for this diseases are neonatal body weight, premature delivery, exposure to smoke, malnutrition, early weaning

PURPOSE: Although influenza virus is one of the most important causes of acute respiratory tract infections(ARTIs) in children, virus isolation is not popular and there are only a few clinical studies on influenza in Korea. We evaluated the epidemiologic and clinical features of ARTIs by influenza virus in children. METHODS: From February 1995 to August 2001, nasopharyngeal aspirations were obtained and cultured for the isolation of influenza virus in children admitted with ARTIs. The medical records of patients with influenza virus infection were reviewed retrospectively. RESULTS: Respiratory viruses were isolated in 997(22.0%) out of 4,533 patients examined, and influenza virus was isolated in 164 cases(3.6%). Influenza virus was isolated year after year mainly from December to April of next year. The ratio of male and female was 1.9 : 1 with a median age of 15 months. The most common clinical diagnosis of influenza virus infection was pneumonia, and fever and cough developed in most patients. There was no difference between influenza A and B infection in clinical diagnoses and symptoms. All patients recovered without receiving antiviral treatment except for one patient diagnosed with pneumonia who had underlying disease of Down syndrome with ventricular septal defect. CONCLUSIONS: ARTIs caused by influenza virus developed every winter and spring during the period of study. Because fatal complication can develop in the high risk group, prevention, early diagnosis and proper management of influenza should be emphasized.
