Prospective randomized clinical trial comparing the effectiveness of immediate arthroscopic stabilization versus immobilization and rehabilitation in first traumatic anterior dislocations of the shoulder.

Our purpose was to compare the effectiveness of traditional treatment with immediate arthroscopic stabilization in young patients who have sustained a first traumatic anterior dislocation of the shoulder. Forty skeletally mature patients younger than 30 years of age were randomly allocated to immobilization for 3 weeks followed by rehabilitation (group T) or arthroscopic stabilization (within 4 weeks of injury) followed by an identical immobilization and rehabilitation protocol (group S). A blinded research assistant performed all follow-up evaluations. The dominant arm was involved in 35% of subjects. The injury occurred in a sporting event in 70% of subjects. At 24 months, there was a statistically significant difference in the rate of redislocation (T = 47%, S = 15.9%, P = .03). An intention-to-treat analysis comparing disease-specific quality of life using the validated Western Ontario Shoulder Instability (WOSI) index showed statistically significantly better results in the surgically treated group at the 33 months (T = 633.93 v S = 287.1, P = .03) and no significant difference in range of motion. At an average 32 months follow-up, a significant reduction in redislocation and improvement in disease-specific quality of life is afforded by early arthroscopic stabilization in patients less than 30 year of age with a first, traumatic, anterior dislocation of the shoulder.

CytoRich liquid-based cervical cytologic test. Screening results in a routine cytopathology service.

OBJECTIVE: To eliminate the disadvantages and inherent bias of split-sample studies by evaluating the relative performance of monolayers and conventional cervical cytologic smears in a single laboratory through evaluation of two large and similar, randomly derived patient groups from the same geographical and demographically similar population. STUDY DESIGN: Two randomly created large patient groups from the same population were evaluated using conventional microscopic screening. One group was tested using the conventional smear. The other was evaluated using only the new liquid-preservative-based CytoRich preparation (AutoCyte, Inc., Elon College, North Carolina, U.S.A.) with the intended direct-tovial cell collection method. Results were then compared statistically as to disease detection and sample adequacy. RESULTS: Age comparisons between the two groups demonstrated equivalency. Specimen adequacy was greatly improved in the group tested with the CytoRich monolayer preparation. The monolayer group also demonstrated a significant reduction in ambiguous atypical squamous cells of undetermined significance/atypical glandular cells of undetermined significance diagnoses and a threefold increase in the detection of squamous intraepithelial lesion and cancer. CONCLUSION: Routine use of homogeneous monolayer preparations as a total replacement for the conventional smear can be expected to dramatically improve specimen adequacy and sensitivity of the conventional smear alone. Direct-to-vial use of the new monolayer preparation generated significantly better results than those shown in any of the earlier split-sample trials.

The development and evaluation of a disease-specific quality of life measurement tool for shoulder instability. The Western Ontario Shoulder Instability Index (WOSI).

The purpose of this study was to develop a valid, reliable, and responsive disease-specific quality of life measurement tool for patients with shoulder instability. Development included 1) identification of a specific patient population; 2) generation of issues specific to the "disease" ("items") from reviewing the literature, interviewing health caregivers, and interviewing patients representing all demographics, disease type and severity, and treatments; 3) item reduction using patient-generated frequency-importance products and correlation matrices; and 4) pretesting the prototype instrument on 2 groups of 10 patients. The final instrument, the Western Ontario Shoulder Instability Index, has 21 items representing 4 domains. The instrument attributes (validity, reliability, and responsiveness) were evaluated. Construct validation demonstrated that this index correlated predictably with other measures. Reliability was very high at 2 weeks and 3 months, and the index was more responsive (sensitive to change) than five other shoulder measurement tools (the Disabilities of the Arm, Shoulder and Hand scale; The American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form; the UCLA Shoulder Rating Scale; the Constant Score; and the Rowe Rating Scale), a global health instrument (the SF12), and range of motion. Since the patient's perception of changes in health status is the most important indicator of the success of a treatment, we suggest that this measurement tool be used as the primary outcome measure to evaluate treatments in this patient population, although it can also be used for monitoring patients' progress in clinical practice.

Synthetic polymer tissue adhesive in the surgery of ascending aortic dissection. Report of two cases.

In Type A aortic dissection preservation of the aortic valve is an attractive proposition. Potential prosthetic valve endocarditis is avoided and there is a low reported incidence of late aortic regurgitation. We report a technique of resuspension of the valve using a synthetic polymer tissue adhesive. This technique allows for the two layers of the dissection to be firmly glued together leaving a good vessel wall for suture placement.
