Current medical student interviewers add data to the evaluation of medical school applicants

Background: There is evidence that the addition of current medical student interviewers (CMSI) to faculty interviewers (FI) is valuable to the medical school admissions process. This study provides objective data about the contribution of CMSI to the admissions process. Method: Thirty-six applicants to a 4-year medical school program were interviewed by both CMSI and FI, and the evaluations completed by the two groups of interviewers were compared. Both FI and CMSI assessed each applicant's motivation, medical experiences, personality, communication skills, and interests outside of the medical field, and provided a numerical score for each applicant on an evaluation form. Both objective and subjective data were then extracted from the evaluation forms, and paired t-test and rank order tests were used for statistical analysis. Results: When compared with FI, CMSI wrote two to three times more words on the applicants’ motivation, personality, communication skills, interests, and overall evaluation sections (p<0.001) and provided about 60% more examples on the motivation section (p=0.0011) and communication skills section (p=0.0035). In contrast, FI and CMSI provided similar numbers of negative examples in these and in the personality section and equivalent overall numerical evaluation scores. Conclusions: These results indicate that when compared with FI, CMSI give equivalent overall evaluation scores to medical school candidates but provide additional potentially useful information particularly in the areas of motivation and communication skills to committees assigned the task of selecting students to be admitted to medical school

Radiographic Comparison of Forearm Symmetry in Healthy Individuals and its Importance in the Diagnosis of Longitudinal Radioulnar Dissociation.

PURPOSE: Longitudinal radioulnar dissociation (LRD) is an injury often missed upon initial presentation. A recent study examined a radiographic screening test in cadavers that showed increased interosseous distance when the interosseous ligament (IOL) was divided. For this test to be clinically useful, it is necessary for uninjured forearms to have similar interosseous spaces. The purpose of this study was to determine the typical differences between right and left interosseous spaces of healthy individuals. METHODS: Anterior-posterior x-rays of bilateral forearms in maximum supination of 28 surgical residents with no history of injury were obtained. These images were uploaded into a picture archiving and communication system and then digitized. The length of the radius was measured (Xr). The maximum interosseous distance (Dmax) between the radius and ulna as well as the interosseous distance at a location 0.3 Xr from the distal radioulnar joint was measured. The right and left arm distances were compared. Also, an outlier analysis was used to evaluate forearm rotational asymmetry between right and left arms. RESULTS: The outlier analysis revealed two sets of forearm x-rays were rotationally different compared to the rest of the group due to asymmetric arm positioning; these data were excluded from the analysis. The average difference in Dmax was 1.7 mm (standard deviation [SD] 1.5) between right and left arms, and this was found at a position of 0.28 Xr on average. The difference in interosseous distance measured at a fixed location 0.3 Xr was 1.6 mm (SD 1.5). No significant difference was found between the paired right and left arms for Dmax or at 0.3 Xr. CONCLUSIONS: There does not appear to be any significant difference between the maximum interosseous distance of right and left arms in healthy individuals. Therefore, analyzing bilateral forearm x-rays may be a simple LRD screening test. CLINICAL RELEVANCE: Understanding the degree of normal variation in the forearm bone spacing might inform evaluation of abnormal forearm bone alignment resulting from LRD

Utility of opposed-phase magnetic resonance imaging in differentiating sarcoma from benign bone lesions

Purpose: To investigate the utility of opposed-phase magnetic resonance imaging (OP MRI) in differentiating malignant from benign bone lesions. Materials and methods: MRI scans of musculoskeletal lesions including opposed-phase imaging sequences were reviewed by both an experienced musculoskeletal attending radiologist, and a second year radiology resident. The change in signal from IP to OP images was measured. The reviewers' evaluation of the lesions based on T1 and T2-weighted images was compared to their evaluation with inclusion of the OP sequences. Results: Twenty-seven lesions in bone were analyzed: 4 malignant primary bone lesions, 3 malignant soft tissue lesions to bone, 3 metastases from visceral malignancies, and 17 benign bone lesions. Benign lesions of bone dropped in signal on OP imaging by an average of 37.1%. Five of the benign lesions decreased in signal by less than 20%, and two increased. Malignant bone lesions dropped in signal by an average of 0.69% with one of the ten lesions showing a greater than 20% drop. When OP sequences were included, concern for malignancy decreased in benign lesions and increased in malignant lesions, for both the resident and attending. Compared with standard MRI, inclusion of these sequences increased the overall confidence in diagnosis for both reviewers. Conclusion: Opposed-phase imaging is helpful in differentiating benign from malignant lesions in bone. Confidence in diagnosis rose for both the attending and the resident as result of the inclusion of OP sequences

The Utilization of Osteoarticular Transfer System in the Treatment of Distal Femur Osteoid Osteoma: A Case Report

Introduction: Tumor excision of the subchondral bone of the distal femur epiphysis is technically challenging particularly in skeletally-immature patients due to the open physis above and articular surface below. Preservation of the physis, maintenance of structural support to, and integrity of, the cartilage, and conservation of joint kinematics must all be considered and are often threatened by current percutaneous or open surgical treatment options. Materials and Methods: We present a case of a 16-year-old male athlete with a distal femur epiphyseal bone lesion. He underwent transarticular en bloc excision and autograft reconstruction using Osteoarticular Transfer System (OATS) technique. Results: Final pathology revealed complete excision of an osteoid osteoma. The patient had regained full strength and range of motion at 3 months postoperatively, and at 21 months postoperatively was free of disease and back to full level of athletic participation. Conclusions: This article describes a technique for excision of subchondral epiphyseal bone lesions in the distal femur in skeletally immature patients that mitigates risk of complications associated with physeal injury, incomplete tumor resection, and iatrogenic injury to the overlying cartilage

Recurrent Adolescent Giant-Cell Tumor of the Scaphoid: Scaphoid Excision with Intracarpal Fusion after Failed Curettage and Bone Grafting

We present a case of the giant-cell tumor of bone in the scaphoid of a 17-year-old female. Imaging revealed an expansile lytic lesion of her scaphoid, and the diagnosis was confirmed with open biopsy. She was treated with curettage and iliac crest bone graft, in an effort to spare reconstruction of her wrist. After one year, she developed increasing tightness and pain. Local recurrence was apparent on radiographs, and CT revealed increased lucency with bony destruction in the area of prior excision. She was successfully treated, without recurrence to date, with complete scaphoid excision and a four-corner wrist fusion. Local recurrence of the giant-cell tumor of bone is high, especially in carpal bones. When treating patients with advanced lesions, more aggressive initial options should be considered
