OBJECTIVE Breast cancer incidence is rising for women in low and middle income country (LMIC)s. Growing the health care workforce trained in clinical breast exam (CBE) is critical to mitigating breast cancer globally. We developed a CBE simulation training course and determined whether training on a low-fidelity (LF) simulation model results in similar skill acquisition as training on high-fidelity (HF) models in Rwanda. DESIGN A single-center randomized educational crossover trial was implemented. A preintervention baseline exam (exam 1), followed by a lecture series (exam 2), and training sessions with assigned simulation models was implemented (exam 3)-participants then crossed over to their unassigned model (exam 4). The primary outcome of this study determined mean difference in CBE exam scores between HF and LF groups. Secondary outcomes identified any provider level traits and changes in overall scores. SETTING The study was implemented at the University Teaching Hospital, Kigali (CHUK) in Rwanda, Africa from July 2014 to March 2015 PARTICIPANTS Medical students, residents in surgery, obstetrics and gynecology, and internal medicine residents participated in a 1-day CBE simulation training course. RESULTS A total of 107 individuals were analyzed in each arm of the study. Mean difference in exam scores between HF and LF models in exam 1 to 4 was not significantly different (exam 1 0.08 standard error (SE) = 0.47, p = 0.42; exam 2 0.86, SE = 0.69, p = 0.16; exam 3 0.03, SE = 0.38, p = 0.66; exam 4 0.10 SE = 0.37, p = 0.29). Overall exam scores improved from pre- to post-intervention. CONCLUSIONS Mean difference in exams scores were not significantly different between participants trained with HF versus LF models. LF models can be utilized as cost effective teaching tools for CBE skill acquisition, in resource poor areas. OBJECTIVE Develop and describe a set of low-cost hemorrhoidectomy task trainer prototypes in the setting of inadequate junior resident surgical skill preparation for anorectal cases. DESIGN This is a study comparing expert and novice performance and opinions. Three task trainers were developed to simulate dissecting, knot-tying, and suturing in a confined space, like the anus. Participants were asked to dissect the peel off of an orange, tie seven 2-handed knots on a weight, and close a defect in a piece of felt with a running stitch. An 8-oz mason jar was used to simulate the confined space. Participants were asked to fill out a 5-point Likert-based evaluation regarding the skills. The primary outcome was time to complete each task in seconds. Secondary outcome measures were number of errors associated with each task, subjective achievability of tasks, and utility of tasks for improving surgical skills. SETTING General surgery residency program at a safety-net academic center. PARTICIPANTS Forty subjects participated in this study. There were 20 experts (7 attending surgeons, 13 PGY-1-PGY-5 surgical residents) and 20 novices (11 third- and 9 fourth-year medical students). RESULTS Experts knot-tied (59s vs 140s, p less then 0.001) and sutured (219s vs 295s, p less then 0.001) faster than novices. Experts were able to tie 7 knots in fewer attempts than novices (p less then 0.001). There was no significant difference in speed of orange dissection between groups. selleck kinase inhibitor There were no significant differences in the number or frequency of other errors. All participants felt the tasks were achievable (4.90/5) and would be useful in improving skills (4.93/5). CONCLUSIONS This study demonstrated that a set of low-cost, low-fidelity prototypical hemorrhoidectomy task trainers can discriminate between experts and novices. Simulation models such as these can offer useful practice opportunities for junior general surgery trainees. Imaging evaluation of the shoulder is performed using multiple modalities, including ultrasound (US) and MR imaging. Clinicians often wonder which modality to use to work up their patients with shoulder pain. Although MR imaging has remained the workhorse of shoulder imaging, US has increased in popularity among academic and private institutions. Both modalities offer similar diagnostic information in regards to rotator cuff pathology and other soft tissues, although they differ in their technique, indications, and interpretation. A thorough understanding of these differences is imperative to appropriately use these modalities in clinical practice, including the unique interventional opportunities available with US. This article discusses the most common tumor and tumor-like lesions arising at the shoulder. Osseous tumors of the shoulder rank second in incidence to those at the knee joint and include benign osteochondromas and myeloma or primary malignant lesions, such as osteosarcoma or chondrosarcomas. Soft tissue tumors are overwhelmingly benign, with lipomas predominating, although malignant lesions, such as liposarcomas, can occur. Numerous tumor-like lesions may arise from the joints or bursae, due to either underlying arthropathy and synovitis (eg, rheumatoid arthritis and amyloid) or related to conditions, including tenosynovial giant cell tumor and synovial osteochondromatosis. Muscle atrophy in shoulders with rotator cuff tendon tears is a negative prognosticator, associated with decreased function, decreased reparability, increased retears after repair, and poorer outcomes after surgery. Muscle edema or atrophy within a neurologic distribution characterizes denervation. Because most nerve entrapments around the shoulder are not caused by mass lesions and show no nerve findings on routine MR imaging sequences, pattern of muscle denervation is often the best clue to predicting location of nerve dysfunction, which narrows the differential diagnosis and guides clinical management. The exception is suprascapular nerve compression in the spinoglenoid notch caused by a compressing cyst. Acromioclavicular joint (ACJ) pathology is a common source of shoulder girdle pain, frequently coexisting with and sharing overlapping clinical features of rotator cuff and glenohumeral articular lesions. ACJ trauma and osteoarthritis dominate clinical presentation; however, an array of pathologies can affect the joint. MR imaging of the ACJ is a powerful secondary diagnostic tool in early diagnosis of ACJ pathology and in accurate assessment of ACJ injuries, helping to resolve clinically challenging cases and allowing for individualized treatment planning. Knowledge of ACJ anatomy, biomechanics, and pathology is fundamental to interpreting and providing a clinically relevant ACJ MR imaging report.
