A longitudinal study of empathy in pre-clinical and clinical medical students and clinical supervisors.

BACKGROUND: Although appropriate empathy in health professionals is essential, a loss of empathy can occur during medical education. The structure of clinical learning may be one factor that is implicated in a loss of empathy. This study examines student and doctor empathy, and possible associations between empathy and the structure of clinical learning. METHODS: There were three groups of participants: medical students (n = 281), who completed a longitudinal survey consisting of the Jefferson Scale of Empathy and an open question about empathy at the beginning and end of the 2013 academic year; private doctors (medical practitioners) in South Australia (n = 78) who completed a survey consisting of the Jefferson Scale of Empathy and an open question about empathy at the end of the students' academic year; and doctors (medical practitioners) from public teaching hospitals (n = 72) in southern Adelaide, South Australia who completed a survey consisting of the Jefferson Scale of Empathy at the end of the students' academic year . RESULTS: Year one students' empathy scores at the end of the year (102.8 ± 17.7) were significantly lower than at the start of the year (112.3 ± 9.6) p < .05). There were no other significant differences in students' empathy scores by year groups or across the two time points. Empathy scores were almost identical for private and hospital clinicians and higher than average scores for students. Free-text comments highlighted the importance students and doctors place on empathy. Students described issues that adversely affected their empathy, including specific incidents, systemic issues, and course structure, but also described some positive role models. Doctors' comments focused on the importance of empathy but qualified its meaning in the therapeutic setting. CONCLUSION: Medical students and practitioners alike ascribe importance to empathy in clinical practice, yet its developmental course remains poorly understood with possible decrement across the course of medical education. A more sophisticated understanding of empathy in medical students is needed, with attention to issues that might adversely impact on this crucial aspect of their development. TRIAL REGISTRATION: This was not undertaken as the research did not involve a health care intervention on human participants.

Noncultured keratinocyte/melanocyte cosuspension: effect on reepithelialization and repigmentation--a randomized, placebo-controlled study.

Randomized controlled trials in the literature investigating the efficacy of noncultured keratinocyte/melanocyte suspensions are scarce; however, the advocates of such techniques press the value of their application based largely on case studies and anecdote. Caucasian patients with burn hypopigmentation seldom request cosmetic revision making worthwhile clinical trials difficult so that informal case treatments with new therapies generate anecdotal results. A randomized, placebo-controlled trial was carried out to evaluate whether cosuspensions of noncultured skin cells are capable of (1) decreasing the time to reepithelialization and (2) reestablishing pigmentation in vitiligo leukoderma following epidermal/superficial dermal ablation (in the knowledge that a positive result would make the technique likely to be successful in burn hypopigmentation). Vitiligo is common and is socially more debilitating such that suitable trial subjects for new therapies from this pool are more forthcoming. This study demonstrated that suspensions of noncultured keratinocytes and melanocytes do not decrease the time to epithelialization of superficial partial thickness wounds compared with controls. It also suggested that the achievement, quality, and duration of any pigmentation were unpredictable and largely disappointing. Some pigmentation was recorded in placebo-treated areas indicating an effect of the method of epidermal ablation in these patients. These findings have mandated a complete review of the use of these techniques in burn care at the Royal Adelaide Hospital; they have been omitted from surgical protocols where the aim of use was to speed reepithelialization. Their infrequent use in burns hypopigmentation will continue contingent on the successful repigmentation of a test patch.

Nipple-areolar pigmentation: histology and potential for reconstitution in breast reconstruction.

The makeup of nipple-areolar skin, in terms of its melanin and melanocyte content has not previously been established. This histological information is required if pigmentation of the reconstructed nipple-areola is to be successful in post-mastectomy breast reconstruction. We describe examination of 200 parallel sections of nipple-areolar skin of 20 women using histochemical (Masson-Fontana) and immunohistochemical (Mel-5) techniques, evaluated using quantitative image analysis. The amount of melanin present per length of basement membrane was 2.14 times higher in areolar skin than breast skin. The ratio of melanocytes to keratinocytes was 1:9.7 in areolar skin vs. 1:14.7 in breast skin. We also describe a cell culture and skin construct method using autologous human serum without toxic growth promoting additives, which could be used in the clinical setting of nipple-areolar reconstruction.
