Use of Student Feedback by Pre-Clinical and Clinical Course Directors

We examined the conceptual and instrumental uses of student feedback on teaching by 2 preclinical and clinical course directors with authority to change structure and content of the courses, assess suitability of instructors and to change methods of student feedback questionnaires have been collected systematically for over 2 decades. A report based on this feedback is sent to course directors, the dean, his assistants and the head of the curriculum committee. Course directors from both groups made broad use of the feedback but made greater use of the report than preclinical course directors. Students had greater regard for individual teaching by clinical course directors than by preclinical course coordinators. No relationship was found between the degree of use of feedback by members of either group and their level of teaching. We conclude that senior faculty use student feedback in their decisions regarding the structure and teaching methods of their courses and are not influenced by individual assessments, positive or negative, by their students.

The gonadotropin-releasing hormone (GnRH) test was performed on 182 patients with various degrees of varicocele before and after low, inguinal, spermatic vein ligation, and on 18 controls. The levels of follicle-stimulating hormone (FSH) and luteinizing hormone, a synthetic GnRH (LH), were evaluated before and 45 minutes after intravenous injection of 100 mcg relisorm L. FSH levels increased more than 2-fold in 118 patients [64.8%] and LH levels increased more than 5-fold in 135 patients [74.1%]). In the control group the increase was less in all cases. Therefor, whenever FSH increased more than 2-fold and LH more than 5-fold, we considered the test positive (pathologic); On this basis the GnRH test was positive in 126 (69.2%) and negative (normal) in 56 (30.7%). Of the 126 with positive tests, only 32 (27.3%) still had a positive result 5-6 months after operation. There was correlation between a positive GnRH test and significant improvement in sperm parameters after varicocelectomy: of the 126 with positive tests before operation, sperm parameters improved in 87 patients (69%), while in the 56 patients with negative tests before operation, in only 7 (12.5%) was there improvement after correction. We conclude that a positive GnRH test indicates impairment of the hypothalamic-pituitary-gonadal axis caused by varicocele and could serve as a marker for surgical intervention with good prediction of outcome.
