Pain levels experienced with activities after cardiac surgery.

BACKGROUND: Acute pain is common after cardiac surgery and can keep patients from participating in activities that prevent postoperative complications. Accurate assessment and understanding of pain are vital for providing satisfactory pain control and optimizing recovery. OBJECTIVES: To describe pain levels for 5 activities expected of patients after cardiac surgery on postoperative days 1 to 6 and changes in pain levels after chest tube removal and extubation. METHODS: Adults who underwent cardiac surgery were asked to rate the pain associated with various types of activities on postoperative days 1 to 6. Pain levels were compared by postoperative day, activity, and type of cardiac surgery. Pain scores before and after chest tube removal and extubation also were analyzed. RESULTS: Pain scores were higher on earlier postoperative days. The order of overall pain scores among activities (P < .01) from highest to lowest was coughing, moving or turning in bed, getting up, deep breathing or using the incentive spirometer, and resting. Changes in pain reported with coughing (P = .03) and deep breathing or using the incentive spirometer (P = .005) differed significantly over time between surgery groups. After chest tubes were discontinued, patients had lower pain levels at rest (P = .01), with coughing (P = .05), and when getting up (P = .03). CONCLUSIONS: Pain relief is an important outcome of care. A comprehensive, individualized assessment of pain that incorporates activity levels is necessary to promote satisfactory management of pain.     

Revisiting Jaccoud arthropathy as an ultrasound diagnosed erosive arthropathy in systemic lupus erythematosus.

Jaccoud arthropathy (JA), now most commonly associated with systemic lupus erythematosus (SLE), is widely perceived as a benign joint deformity that is radiographically nonerosive and that confers little if any disability. Advances and accessibility of imaging modalities such as ultrasound (US) are challenging the complacency in perceiving SLE-JA and SLE arthritis as benign processes. Prompted by a patient with SLE-JA in which joint erosion was detectable on US but not evident on radiograph, this review assesses the potential utility of US to guide management and promote understanding of SLE arthritis and its poorly understood pathogenesis.     

Intracardiac transplantation of a mixed population of bone marrow cells improves both regional systolic contractility and diastolic relaxation.

BACKGROUND: Pre-clinical and clinical studies suggest that transplantation of bone marrow-derived stem cells can improve global cardiac function. However, no quantitative assessment of regional systolic contraction and correlation with phenotype has been made. Therefore, we used our model of cryoinfarcted rabbit myocardium for intracardiac transplantation of a mixed population of bone marrow-derived cells and assessed both regional function and myogenic conversion of the cells. METHODS: Nineteen New Zealand white rabbits underwent cryoinjury of the left ventricle. Autologous bone marrow (BM) cells were expanded in vitro. After 2 weeks, either 1 x 10(8) mixed BM-derived progenitor cells (BM group, n = 11) or vehicle (control group, n = 8) were injected into the cryoinjured region. Regional systolic function was measured using micromanometry and sonomicrometry before and 4 weeks after cell injection; cell phenotype was evaluated histologically. RESULTS: All animals in the BM group significantly improved both systolic shortening (0.11 +/- 0.7 vs -0.05 +/- 0.05 mm in the control group, p < 0.05) and regional stroke work when compared with control (9.6 +/- 2.4 vs -1.2 +/- 1.2 mm . mm Hg, p < 0.003). In addition, the BM group had improved global diastolic function, as measured by minimum dP/dt and end-diastolic pressure. On histologic assessment, BM cells differentiated toward a myogenic phenotype. CONCLUSIONS: Transplanting a mixed population of marrow-derived cells that can adopt a myogenic phenotype improves regional contractility and diastolic relaxation after myocardial infarction.     

Managing catheter dysfunction for better patient outcomes: a team approach.

Vascular access is the leading cause of morbidity in the hemodialysis patient population. Arteriovenous fistulas (AVFs) have the lowest complication rate while catheters have the highest. Though significant effort is being made to increase the number of AVFs and lower the number of catheters, annual data show that the number of catheters is increasing. To improve vascular access-related patient outcomes, catheter dysfunction needs to be managed by a vascular access team using the CQI process that begins with a comprehensive algorithm for treatment.     

Comparison and item analysis of the MESSY for autistic and normal children

Seventeen autistic children were matched for age, race, and sex with 17 nonautistic children, and group differences in social skills were assessed. Appropriate social skills and levels of inappropriate assertiveness/impulsiveness were assessed and evaluated using the Matson Evaluation of Social Skills with Youngsters (MESSY). Significant differences in both the appropriate and inappropriate social behaviors displayed by the two groups were found. The implications of these results are discussed.
