Nutritional risk screening of inpatient children with singer-center gastroenterological diseases in Sichuan province

Objective To evaluate the application of clinical Screening Tool for the Assessment of Malnutrition in Pediatrics(STAMP), and to investigate the nutritional risks of inpatient children with gastroenterological diseases in Sichuan province and their associated clinical characteristics and the features of hygiene economics. Methods STAMP was utilized for nutrition screening of inpatient children with gastroenterological diseases in Chengdu Women and Children′s Central Hospital from January 2015 to March 2017.All the enrolled children were divided into 3 groups accor-ding to the STAMP scores: low risk group (LR group), moderate risk group (MR group) and high risk group (HR group). Clinical and economic data were compared among 3 groups. Results A total of 3 672 assessments were accomplished, including 2 372 times for males and 1 300 times for females( 5 years old: 848 times). Among them, 147 children were identified as LR(4.00%), 2 296 children as MR (62.53%), and 1 229 children as HR (33.47%). Statistically significant differences were observed among 3 groups in average length of hospital stay (P 0.05). Malnutrition rate was 4.08%(6/147 cases) in LR group, 2.05%(47/2 296 cases) in MR group and 31.90%(392/1 229 cases) in HR group, respectively, and among them 146 patients were diagnosed as severe malnutrition.Digestive tract infections were the most common diseases in MR group(66.33%, 1 523/2 296 cases) and HR group(68.27%, 839/1 229 cases). Moreover, children with stomatitis, gastrointestinal postoperation, acute pancreatitis, inflammatory bowel disease, esophageal diseases, digestive malformations, cyclic vomiting, malnutrition, and acute intestinal obstruction were all in HR group. Conclusions Nutritional risk is likely to raise the burden of disease.STAMP is applicabile clinically when it is utilized for nutrition risk screening of inpatient children with gastroenterological diseases in Sichuan province and provides evidence for nutrition support treatment.

Imaging manifestations and its clinical significance in patients with synovitis acne pustulosis hyperostosis osteomyelitis syndrome

Objective To describe the clinical and imaging manifestations of patients with synovitis acne pustulosis hyperostosis osteomyelitis (SAPHO) syndrome,and to analyze the diagnostic importance of different clinical and imaging manifestations for SAPHO syndrome. Methods Seventeen patients (7 males and 10 females) with SAPHO syndrome were recruited in this study.Age ranged from 36 to 67 years with a mean age of (48 ± 8) years. All patients fulfilled the diagnostic criteria of Benhamou. Serum HLA B27 antigen records were reviewed for all patients. Imaging data of the abnormal bone sites were collected by conventional radiograph in all patients,CT in 13 patients as well as MR in 3 patients.Average time to take for a definite diagnosis of the syndrome was 3.7 years (ranged from O.5 to 13 years).Results Serum HLA B27 antigen was positive in all patients. Both skin and bone abnornalities were found in all patients.Ten patients had skin palmoplantar pustulosis and two patients had acne. Involving sites of bone and joints include sacroiliac joints,anterior chest and limbs.Sacroiliac joints were asymmetrically involved with imaging features in all patients.Eight patients exhibited anterior chest wall involvement. Five patients had osteomyelitis at limbs. For all images of 17 patients,CT was superior to conventional radiography in detecting abnormal changes of bone erosion and soft tissue swelling.MR imaging was able to depict edema changes that was not detectable by CT and radiography.Conclusion SAPHO syndrome is a rare disease,but for patients with skin and bone-joint abnormalities,especially with skin palmoplantar pustulosis,acne as well as with imaging features at the sacroiliac joint and anterior chest wall,SAPHO syndrome should be taken into a diagnostic consideration.

Early diagnosis and staging of rheumatoid arthritis by MR imaging and ultrasonography

Advanced imaging modalities, such as MR imaging or ultrasonography (US), are useful in evaluating disease activity and therapeutic outcome of rheumatoid arthritis (RA). MR imaging can demonstrate bone erosion and edema, which are important in predicting structural articular damage. MR findings are nonspecific but can be helpful in diagnosing RA in its early stage. US can access relatively easily to multiple joints, and power Doppler US allows to visualize the vascularity of synovium. Standardization of imaging and analysis procedures are needed for clinical application of these imaging modalities.

Improved Prediction of Acute Stroke Outcome with Multimodal CT

Unenhanced CT scanning and clinical exam alone have a restricted ability to predict functional outcome in patients with acute stroke and, therefore, have a limited value for clinicians in selecting patients for urgent thrombolytic therapy. Advanced techniques such as MR diffusion/perfusion imaging are increasingly advocated for patient triage. These authors prospectively evaluated the predictive value of a contrast-enhanced, CT-based scoring system called Multimodal Stroke Assessment Using CT (MOSAIC). The 4 components of the MOSAIC …
