RESUMO
Background: Oral examinations are a useful tool to appraise certain medical skills compared to other examinations. However, they have some disadvantages that might be reduced with standardization. Aim: To compare students’ perception comparing a standardized oral exam (SOE) versus a traditional, non-standardized oral exam (NSOE). Material and Methods: During the first semester of 2013 a NSOE was applied to internal medicine undergraduate students. During the second semester, a SOE was applied. An anonymous and voluntary perception questionnaire, consisting in 10 questions based on a 5-level Likert scale, was answered by these students. Statistical analysis was done using the Mann-Whitney U test. Results: Among the 118 students, 50.8% were evaluated using NSOE and 49.2% using SOE. Questionnaire response rate was 84%. Among respondents, 52% took the SOE and 48%, the NSOE. Students evaluated using SOE perceived that the degree of complexity of clinical cases was similar for all examinees (p < 0.05), that exam duration was standardized (p < 0.05), and that grades obtained were less influenced by the clinical site where the exam was taken (p < 0.05). However, anxiety level remained high in both groups, as well as the overall satisfaction experience. Conclusions: Standardization of an oral examination improves the perception of medical students about levels of difficulty, duration and external influences on the final grade.

Tumor induced osteomalacia is uncommon and is characterized by an isolated and not PTH dependent reduction in tubular phosphate reabsorption. This alteration is produced by phosphaturic factors, such as fibroblast growth factor-23 (FGF-23) that are secreted by tumors. We report a 41 years old female presenting with joint pain and progressive loss of muscle strength in the lower limbs. Initial laboratory assessment showed hypophosphatemia, elevated alkaline phosphatases, normal intact parathormone levels, low levels of 25 hydroxy vitamin D and an elevated 24 h phosphaturia. Bone mineral density showed spine and femoral neck osteopenia. A positron emission tomography (PET) revealed a right thigh tumor with lung metastases. Its biopsy disclosed a fibrosarcoma. FGF-23 levels, measured by ELISA were markedly elevated. The patient was discharged with palliative measures.
