Inhalation lung injury induced by smoke bombs in children: CT manifestations, dynamic evolution features and quantitative analysis.

Background: This retrospective study aimed to investigate the computed tomography (CT) manifestations, short-term dynamic evolution features and quantitative lung CT analysis of inhalation lung injury induced by smoke bomb flare.

Methods: Eleven pediatric patients (aged 11 to 13) who inhaled the smoke of smoke bombs underwent several low-dose chest CT scans. The image characteristics and their dynamic changes were observed and quantitative CT values were analyzed.

Prediction of calcium level in melamine-related urinary calculi with helical CT: diagnostic performance evaluation and clinical significance.

The aim of the study was to investigate the relationship between CT-attenuation and stone calcium level in melamine-related urinary calculi (MRUC). A total of 25 MRUC with known composition and calcium level were included (11 uric acid stones, 2 calcium oxalate stones and 12 mixture stones of uric acid and calcium oxalate). Of all, 18 renal stones accepted alkalization therapy except for 5 lower urinary tract stones and 2 stones of unknown position.

Clinical characteristics of refractory melamine-related renal calculi.

Objective: The melamine urinary stones are uric acid-based and amenable to alkalization and extracorporeal shock-wave lithotripsy (ESWL). However, a significant percentage of stones failed in alkalization and ESWL. To predict it before a likely deemed failed treatment, we attempt to confirm their clinical characteristics.

Study of stone composition changes in melamine-related urinary calculi and its clinical significance.

Objectives: To investigate the composition changes in melamine-related urinary calculi and their clinical significance.

Methods: A total of 49 melamine-related urinary calculi were included from 49 children (age 4-82 months, mean 22). The qualitative analysis of stone composition was determined using Fourier transform infrared.
