Human bocavirus was detected in 57 (18.3%) of 312 children with acute respiratory infection (ARI) who required hospitalization in Jordan. It was also detected in 30 (21.7%) of 138 children with severe ARI, in 27 (15.5%) of 174 with mild or moderate disease, and in 41 (72%) of 57 with other pathogens.
Human respiratory syncytial virus (HRSV) is the major viral cause of acute lower respiratory tract infections in children. Few data about the molecular epidemiology of respiratory syncytial virus in developing countries, such as Jordan, are available. The frequency and severity of infections caused by HRSV were assessed in hospitalized Jordanian children <5 years of age compared with other potential etiological agents. Overall a potential pathogen was detected in 78% (254/326) of the children. HRSV was detected in 43% (140/326) of the nasopharyngeal aspirates. HRSV was found more frequently during the winter (January/February), being less frequent or negligible by spring (March/April). Analysis of 135 HRSV-positive strains using restriction fragment length polymorphism showed that 94 (70%) belonged to subgroup A, and 41 (30%) to subgroup B. There were also two cases of mixed genotypic infection. Only four of the six previously described N genotypes were detected with NP4 predominating. There were no associations between subgroup or N-genogroup and disease severity. HRSV was significantly associated with more severe acute respiratory infection and the median age of children with HRSV was lower than for those without. Next in order of frequency were adenovirus (116/312: 37%), human bocavirus (57/312: 18%), rhinovirus (36/325: 11%), Chlamydia spp. (14/312: 4.5%), human metapneumovirus (8/326: 2.5%), human coronavirus NL63 (4/325: 1.2%), and influenza A virus (2/323: 0.6%). Influenza B; parainfluenza viruses 1-4, human coronavirus HKU1 and Mycoplasma pneumoniae were not detected.
To describe the clinical presentation, course and management of infants that presented with the diagnosis of lymphadenitis after Bacille Calmette-Guerin (BCG) vaccination. This is a descriptive study of 89 patients that were referred to the pediatric infectious disease clinic at King Hussein Medical Center in Jordan with regional lymphadenitis after BCG vaccination. The presentation, course and treatment options of these cases were discussed. The study was conducted between September 2006 and September 2007. Eighty-nine patients (47 males (53%) and 42 females (47%) were studied. All infants received the same type of vaccine used by our Ministry of Health, which is the Danish strain. Unilateral axillary lymph node enlargement was the most commonly seen (47%). Cervical lymph nodes were noted in 22 patients (25%) and supraclavicular lymphadenopathy was seen in 16 (18%). Sinus formation was seen in 16 (18%) patients. 27 cases (30%) had fluctuating lymph nodes. Four infants had disseminated infection. The majority (65%) of patients had their symptoms starting within the first 2 months after BCG vaccination. Forty-two (47%) infants had conservative observational management. Anti-tuberculosis medications were commenced in 27 (30%). Surgical excision was performed in 10 (11.5%) cases. All infants but one had complete recovery by the end of the study period. BCG lymphadenitis is a potential complication that necessitates an early recognition and implementing appropriate treatment protocols. Complete healing of suppurative lymphadenitis after BCG vaccine can be achieved using different treatment protocols.
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.
