ABSTRACT
Objective To review the clinical feature of Nocardia-positive patients and improve the awareness of Nocardia infection.Methods The clinical data were reviewed retrospectively for 11 patients from whom Nocardia was isolated during the period from May 2012 to December 2014 in the General Hospital of Ningxia Medical University.Results Contamination was suspected in 2 of the 11 cases.Nocardia infection was considered in the remaining 9 cases,including pulmonary infection in 6 cases,skin and soft tissue infection in 2 cases,peritoneal dialysis-related peritonitis in 1 case.Underlying diseases were documented in all the 9 patients,4 of which received corticosteroids or immunosuppressants for their underlying diseases.Conclusions Nocardia may cause infection in different body sites,especially lungs.The patients with underlying diseases,especially those receiving corticosteroids or immunosuppressants,are relatively more susceptible to Nocardia infections.
ABSTRACT
Objective To study the clinical value of capsule endoscopy for small bowel diseases in pediatric and adolescent patients.Methods Clinical data of 61 pediatric and adolescent patients who underwent capsule endoscopy from February 2007 to April 2014 was respectively analyzed.The positive diagnostic results and safety were observed.Results Of 61 patients,the CE procedures were completed successfully in 58 patients,and failed in 3 patients because of the gastric stasis.Forty-one positive lesions were found in small intestine,and the detection rate was 70.69％.Positive findings included angiodysplasias,Crohn' s disease,Meckel diverticula,ulcer,P-J syndrome,protrusion lesion and enteritis,etc.Finally,29 patients were confirmed (50％),3 (5.17％) were misdiagnosed and 1 (1.72％) was missed.Twenty-two patients underwent other small bowel examinations besides the capsule endoscopy.And the accuracy of capsule endoscopy was 81.82％.All capsules were successfully swallowed by the patients and evacuated within two weeks.No complications such as capsule retention or intestinal obstruction occurred.Conclusion Capsule endoscopy is a safe and well tolerated procedure with high diagnostic rate,which has a prospective clinical value in small bowel diseases in pediatric and adolescent patients.
