Effect of the use of a video tutorial in addition to simulation in learning the maneuvers for shoulder dystocia.

The development of video tutorials is flourishing and may make it possible to maintain knowledge learned during instruction with simulation. The aim of this study was to assess the effect of adding a video tutorial to a lecture and simulation for learning the maneuvers and protocol for the management of shoulder dystocia. Student midwives and medical students attended a lecture class including instruction about maneuvers and a presentation of an algorithm for the management of shoulder dystocia. They were randomized into two groups. The video group was reminded every two weeks to watch a short tutorial. The control group was reminded to consult the slide show. At the end of two months, they were evaluated by graders. The practice, theory, and global scores of the students in the video group were significantly higher than those of the students in the control group (14.8 vs. 10.4; 5.6 vs. 3.4; and 9.3 vs. 7.0, P<0.001). The scores for the video group improved at the second simulation session, compared with the first (14.8 vs. 9.9; 5.6 vs. 2.9; and 9.3 vs. 7, P<0.001). The addition of a video tutorial improved learning compared to a standard lecture and simulation session alone.

Conservative treatment feasibility with induction chemotherapy, surgery, and radiotherapy for patients with breast carcinoma larger than 3 cm.

BACKGROUND: The traditional surgical treatment for operable breast carcinoma larger than 3 cm is mastectomy. To avoid mutilating surgery, the authors administered primary chemotherapy to 158 patients with operable nonmetastatic large breast carcinoma with a TNM classification of T2 greater than 3 cm and T3 with a lymph node status of N0-N1. Conservative treatment was proposed for patients responding to the chemotherapy and whose tumor was reduced to 3 cm or less. The purpose of the study was to evaluate the feasibility and treatment results of this strategy. METHODS: The mean patient age was 50.4 years. Eighty-two patients had T2 carcinomas greater than 3 cm, and 76 had T3 carcinoma. Fifty-four tumors were classified as lymph node status N0, and 104 as N1. Mean tumor size was 5.6 cm. Patients were treated with three courses of the NVCF regimen (mitoxantrone, vindesin, cyclophosphamide, and 5-fluorouracil) or the EVCF regimen, in which mitoxantrone was replaced by epirubicin every 4 weeks, and then administered with a radiosurgical combination. RESULTS: The overall response rate to induction chemotherapy was 60.8% with 20.2% complete tumor regression. Twenty-one percent of the patients experienced grade 3 or 4 chemotherapy toxic effects, which were all acceptable and reversible. Breast-conserving treatment was feasible in 48.7% of patients (77 of 158). Forty-five patients (28.5%) were treated with a radiosurgical combination (tumorectomy plus radiation therapy), whereas 32 (20.2%) were treated with radiotherapy alone (external irradiation and brachytherapy). Other patients were treated with mastectomy. Age, tumor stage, histology, hormonal status, and hormonal receptor rate had no influence on the frequency of the observed regressions. Isolated recurrences occurred in 11 patients, 6 who were treated conservatively and 5 who were treated with mastectomy. Metastatic relapses were observed in 38 patients (14.6% in the chemotherapy responders and 38.7% in the nonresponders) (P < 0.02). Five-year actuarial survival was 73.2% and was significantly higher for responders to the induction treatment. CONCLUSION: These preliminary results suggest that primary chemotherapy and radiosurgical breast-conserving treatment is feasible and is an alternative to mastectomy for patients with large operable breast carcinoma who are responders to the induction treatment. The long term benefit of this strategy must be evaluated in well designed controlled trials.
