Clinical and microbiological characteristics of children with drowning-associated aspiration pneumonia / 中国当代儿科杂志

OBJECTIVES@#To study the clinical and microbiological characteristics of children with drowning-associated aspiration pneumonia, so as to provide a reference for empirical selection of antibacterial agents.@*METHODS@#A retrospective analysis was performed on the medical data of 185 children with drowning-associated aspiration pneumonia who were admitted to Children's Hospital of Chongqing Medical University from January 2010 to October 2020. According to the drowning environment, these children were divided into four groups: fecal group (n=44), freshwater group (n=69), swimming pool group (n=41), and contaminant water group (n=31). The clinical characteristics and pathogen detection results were reviewed and compared among the four groups.@*RESULTS@#The 185 children had an age of 4 months to 17 years (median 34 months). Sputum cultures were performed on 157 children, and 103 were tested positive (65.6%), with 87 strains of Gram-negative bacteria (68.5%), 37 strains of Gram-positive bacteria (29.1%), and 3 strains of fungi (2.4%). Gram-negative bacteria were the main pathogen in the fecal group and the contaminant water group, accounting for 88.2% (30/34) and 78.3% (18/23), respectively. The freshwater group had a significantly higher detection rate of Gram-positive bacteria than the fecal group (P<0.008), and the swimming pool group had an equal detection rate of Gram-negative bacteria and Gram-positive bacteria.@*CONCLUSIONS@#For pulmonary bacterial infection in children with drowning in feces or contaminant water, antibiotics against Gram-negative bacteria may be applied empirically, while for children with drowning in a swimming pool or freshwater, broad-spectrum antibiotics may be used as initial treatment, and subsequently the application of antibiotics may be adjusted according to the results of the drug sensitivity test.

Neumonía lipoidea exógena aguda por aspiración accidental de hidrocarburos / Acute exogenous lipoid pneumonia for accidental aspiration of hydrocarbons

La neumonía lipoidea es una enfermedad respiratoria poco conocida que resulta de la acumulación de lípidos de origen endógeno o exógeno a nivel del alveolo pulmonar. Suele ser subdiagnosticada ya que la presentación clínica es inespecífica, por lo que suele confundirse con otras patologías broncopulmonares. Se presentó el caso de un paciente de 18 años antecedentes de aspiración accidental de combustible que seis horas después comenzó con fiebre, hemoptisis, tos y disnea. Se realizó radiografía de tórax donde se observó una neumonía en base derecha que unido al interrogatorio y a la realización de la broncoscopía confirmaron el diagnóstico de neumonía lipoidea. El paciente evolucionó favorablemente con el tratamiento(AU)

Lipoid pneumonia is a little known respiratory disease that results from the accumulation of lipids of endogenous or exogenous origin in the pulmonary alveolus. It is usually underdiagnosed since the clinical presentation is nonspecific, which is why it is often confused with other bronchopulmonary pathologies. We report the case of an 18-year-old patient with a history of accidental fuel aspiration, who ran fever six hours later, together with hemoptysis, cough, and dyspnea. Chest X-rays showed a right base pneumonia. The questioning and the performance of the bronchoscopy confirmed the diagnosis of lipoid pneumonia. The patient evolved favorably with the treatment(AU)
