Objective To identify the occurrence and microorganism profile of device-associated healthcare-associa-ted infections (DA-HAIs)in the intensive care unit (ICU)of a university hospital in China.Methods From Janua-ry 1 to November 30,2015,patients admitted to the ICU of a university hospital in China for more than 48 hours were performed prospective descriptive study. DA-HAIs were defined according to the criteria of the Centers for Disease Control and Prevention (CDC)of U.S.,descriptive statistical analysis was performed.Results Of 254 pa-tients admitted to ICU,the overall incidence of DA-HAIs was 15.35% ,with 10.23 cases of DA-HAIs per 1 000 ICU-days;the incidence of ventilator-associated pneumonia (VAP ),catheter-associated urinary tract infection (CAUTI),and central line-associated bloodstream infection (CLABSI)were 7.05 per 1 000 ventilator-days,4.91 per 1 000 urinary catheter-days,and 3.22 per 1 000 central line-days,respectively. The main infection site was lower respiratory tract,accounting for 48. 27% ,followed by bloodstream system (27. 59% ),urinary tract (22.99% ),and gastrointestinal tract(1.15% ). The major isolated microorganism was Acinetobacterbaumannii (21 .52% ).Conclusion The surveillance system can identify the epidemiological status of DA-HAIs and make effec-tive control measures to ensure the healthcare safety.

A case of anti-neutrophil cytoplasmic antibodies (ANCA)-associated vasculitis (AAV) with ocular masses as the main manifestation was reported. The patient was a middle-aged female, the initial symptom was eye swelling, pulmonary nodules were found before eye surgery, and further examination revealed proteinuria, hematuria and renal insufficiency. Renal pathology showed ANCA-associated glomerulonephritis. The final diagnosis was eye, kidney and lung lesions caused by AAV. Treatment with glucocorticoids and cyclophosphamide resulted in improvement in eye, kidney, and pulmonary lesions. Atypical clinical manifestations of AAV may lead to delayed diagnosis, and attention should be paid to the exclusion of AAV for ocular masses of unknown cause.
