Background:The global epidemiology of meningococcal disease varies markedly by region and over time. In Nepal, information on serogroup of meningococci is not available since the 1983 serogroup A epidemic in Kathmandu. Objective:To provide some fundamental data on the circulating serogroups of meningococci for potential meningococcal immunization programs in Nepal. Methods:This cross-sectional prospective study was conducted from January 2017 to December 2018 among 387 clinically suspected meningitis cases. Cerebrospinal fluid samples were collected by lumbar puncture technique at five referral hospitals of Kathmandu and processed by conventional cultural techniques. Neisseria meningitidis was identified by colony morphology, Gram staining and oxidase test. Serogrouping of meningococci was performed by slide agglutination test. Antibiotic susceptibility testing was done by the modified Kirby Bauer disc diffusion method. The data was entered into IBM SPSS Statistics 21 software and a p-value of <0.05 was considered significant. Results:Thirty-two samples were positive by culture for a bacterial pathogen with 2.3% of meningococci. All except one meningococcal meningitis cases were aged below 15 years. All N.meningitidis isolates belonged to serogroup A and were susceptible to ceftriaxone, chloramphenicol, meropenem and minocycline; however, 22% isolates showed resistance to cotrimoxazole and 11% intermediate resistance to ciprofloxacin. Conclusion:The circulating serogroup of N. meningitidis in Kathmandu has not changed over the past 35 years. The prevalence of meningococcal meningitis in Kathmandu is low but might be underestimated due to the sole use of culture-based diagnostic methods. Detection of meningococci by alternative methods may be useful in the precise estimation of actual disease burden.
Foreign body aspiration is common in children and adolescents. Foreign body aspiration is often unnoticed and diagnosis may be delayed in children, as many fail to provide a history. Although rigid bronchoscopy is preferred modality, flexible bronchoscopy is also a useful tool for foreign body extraction from the distal airways in selected cases. An eleven-year-old boy presented with a history of fever and dry cough of one month's duration. A chest x-ray showed a linear radiopaque foreign body along the course of the right bronchus. Flexible bronchoscopy revealed a metallic nail-like structure in right lower lobe bronchus which was successfully grasped with the flexible forceps and extracted via the oral route with the bronchoscope. Upon extraction aspirated foreign body was found to be a push-pin.
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.
