ABSTRACT
Objective To analyze the clinical features of melioidosis spleen abscess.Methods A retrospective analysis of 26 cases with melioidosis spleen abscess at Hainan People′s Hospital between October 2002 and March 2015 was performed.Data with general conditions, clinical characteristics, imaging features, treatment and outcome were all extracted and analyzed.Results High fever (100.0%) and splenomegaly (73.1%) were the main clinical symptoms and signs.Laboratory examinations showed that white blood cell and neutrophil percentage increased, with a mean value of 12.6×10.9/L and 0.86, respectively.88.5% cases had diabetes mellitus which was the main underlying disease.Apart from spleen abscess, pulmonary infection (73.1%) and liver abscess (38.5%) were the majority.Imaging showed multiple small abscess (92.3%).All patients had at least one positive blood culture of Burkholderia pseudomalleiand were treated with imipenem, ceftazidime and sulfamethoxazole alone or in combination.Hospitalization days ranged between 8 to 65 days with the mean of 29.5 days.Twenty-three cases (88.5%) were cured, the remaining 3 cases (11.5%) abandoned treatment and were all lost for follow-up.Conclusions Melioidosis should be suspected in patients from epidemic areas, who have diabetes and imaging shows spleen abscess and other organ infections including pulmonary infection and liver abscess.Microbiological culture is needed immediately.
ABSTRACT
Objective To study the early diagnostic indices of melioidosis by analyzing 49 cases. Methods Unconditional logistic regression analysis was used to analyze the clinical data of 49 cases of melioidosis and 98 cases of bacterial pneumonia who were admitted in our hospital and Peoples' Hospital of Hainan Province from December 1996 to December 2007. Their social characteristic,background diseases,clinical manifestations,laboratory findings,radiologic examination and complications were studied. Results Background disease (such as diabetes),hepatosplenomegaly,septic shock,sepsis et al were the main causes of melioidosis. Conclusion Chills,fever,hepatosplenomegaly,diabetes mellitus,septic shock and sepsis are all factors that should be considered with melioidosis.
ABSTRACT
Objective The study the formative causes of low dense area in lung on CT images during expiration.Methods This group included 15 young volunteers,mean age was 22 years.Thin sections of spiral CT at right middle hilum were scanned at suspended deep inspiration and deep expiration on both supine and prone positions.The density and area of lobes on matching structural images in the middle hilum at deep inhalation and exhalation were measured on the supine and prone.The increasing rate in area and absolute increasing value in attenuation as full inhalation comparing to full exhalation were calculated.Results Changes of distention and density in the same section of the right lower lobe on dependent position were greater than that on nondependent one.Correlation between distention and density of the lobes was high(P
