The prevalence of asthma showed a significant decrease compared to previous studies. However, there was an unexpected high prevalence of rhinitis. Exposure to acetaminophen and antibiotic during the first year of life was highly associated with asthma symptoms.
To describe the impact following a 1-dose Varicella vaccination schedule introduced in Costa Rica in September 2007. Areas covered: This is a retrospective review using epidemiologic surveillance national databases of varicella cases and hospitalizations, period 2000-2015. We analyzed age-related varicella incidence cases and hospitalization trends before and after the vaccine introduction. Expert commentary: Varicella vaccine coverage among children 16 months age increased from 76% in 2008 to 95% in 2015. During this period Costa Rica reached a 73.8% reduction of Varicella reported cases and 85.9% reduction of hospitalizations in the general population. Among children under 5 years of age, that reduction was 79.1% and 87%, respectively. Varicella complications in hospitalized patients decreased 98%, from n = 53 in 2008 to n = 1 in 2014. After 8-years post implementation of a 1-dose schedule of universal varicella vaccination, a dramatic overall disease reduction in incidence, hospitalizations and complicated cases has been observed in all age groups.
We found a substantial number of asymptomatic infections in Costa Rican children. This greatly increases the risk of dengue hemorrhagic fever or dengue shock syndrome in these children, in whom previous dengue infection had gone undetected. Preventive efforts should be targeted at the costal region due to the higher prevalence in this area.
Background: SARS-CoV-2 variations as well as immune protection after previous infections and/or vaccination may have altered the incidence of multisystemic inflammatory syndrome in children (MIS-C). We aimed to report an international time-series analysis of the incidence of MIS-C to determine if there was a shift in the regions or countries included into the study. Methods: This is a multicenter, international, cross-sectional study. We collected the MIS-C incidence from the participant regions and countries for the period July 2020 to November 2021. We assessed the ratio between MIS-C cases and COVID-19 pediatric cases in children <18 years diagnosed 4 weeks earlier (average time for the temporal association observed in this disease) for the study period. We performed a binomial regression analysis for 8 participating sites [Bogotá (Colombia),
ObjectivesAlthough devastating acute effects associated with snake envenoming are well described, the long-term sequelae resulting from these envenomings have not been adequately addressed, especially in the paediatric population. The aim of our study is to describe the clinical characteristics among paediatric patients in Costa Rica who developed long-term sequelae secondary to snakebite envenoming.DesignRetrospective descriptive study of paediatric patients under 13 years who were admitted with a history of a recent snakebite at the National Children’s Hospital in Costa Rica from January 2001 to December 2014.ResultsWe enrolled 74 patients admitted to our centre due to envenoming, and separated those who did not develop sequelae (50 patients) from those who did (24 patients). Of those who presented acute complications during hospitalisation, local wound infection and clinically diagnosed compartmental syndrome were significantly higher in the group that developed sequelae thereafter. Hypertrophic scars (66.7%), functional limitation of affected limb (37.5%) and the need of skin graft (37.5%) were the most common sequelae. The median follow-up of patients with long-term sequelae after discharge was 25.4 months (5.6–59.4). No deaths were reported during this time period.ConclusionsGiven the high economic, personal and healthcare burden that entails follow-up of these patients, efforts should be carried out to prevent the factors associated with sequelae among the affected population.
Secondary bacterial infections following Viperidae snakebite envenomation in children are common. Among 75 patients admitted because of snakebites at the only pediatric hospital in Costa Rica, 16 (21.3%) had a cultureconfirmed secondary bacterial infection. Morganella morganii (37.5%), Aeromonas hydrophila (31.2%), and Providencia rettgeri (18.7%) were the most common pathogens. Empiric prophylaxis is still recommended and should be based on local etiological agents and antimicrobial susceptibilities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
