Feedback in clinical education

The feedback is a central component of medical education. Unfortunately, medical teachers often believe thatprovide adequate feedback to students. But several studies show confl icting results. The aim of this paper is toreview the main concepts associated to feedback in clinical education as part of the teaching–learning process.

"SERUMS" Program (Rural and Urban Margin Health Care Services) and migration of doctors: Regarding a chohort of doctors in Lima

Sr. Editor. En el último número de su revista se menciona que uno de los problemas del Servicio Rural y Urbano-Marginal en Salud (SERUMS), además de su inconstitucionalidad, es que no contribuye a la retención del personal de salud (1). Nosotros hicimos una cohorte conformada por 166 médicos egresados de las facultades de medicina de Lima Metropolitana, a los que les preguntamos su intención de trabajo en provincias antes y después de la realización del SERUMS.

Factors associated with the regular use of sources of information by medical students from four cities of Peru

Objetives. To determine the factors associated with regular use of sources of information by medical students in four cities in Peru. Materials and methods. In this cross-sectional study, medical students were surveyed in four cities of Peru, gathering information on the use of 14 sources of information and other educational and computer variables. Frequent use of the information source was defined if the respondent reported that they access an information source at least once a week. P values were obtained by generalized linear models adjusted for each respondent site. Results. 2,300 students were surveyed. The median age was 21 years and 53% were women. Having received training in the use of sources increased the use in twelve of the consulted bases, not in SciELO (p=0.053) or in the university library (p=0.509).When adjusting for owning a laptop/netbook, these associations remained. After also adjusting for owning a smartphone the association was lost with the BVS Peru database (p=0.067). The association was also lost after making the final adjustment, if the respondent had carried out any research activities. Conclusions. The frequent use of sources of information is associated with having received training, conducting research and use of information technologies and communication. This should be taken into account in training programs and continuous improvement in undergraduate education

Hypercalcemia-induced pancreatitis in a patient with parathyroid adenoma and thyroid papillary carcinoma

Acute pancreatitis due to hypercalcemia secondary to primary hyperparathyroidism is a rare aetiology. We present a female patient with pancreatitis; with prior cholecystectomy, no alcohol usage or dyslipidemia. Laboratory studies showed, serum calcium 17.93 mg/dL and iPTH 441 pg/ml. Neck CT showed multinodular goiter and a parathyroid nodule. The patient underwent surgery after which serum Ca and PTH decreased. Biopsy showed follicular variant papillary thyroid carcinoma. This report discusses possible theories of association between parathyroid adenoma and hypercalcemic pancreatitis and describes the association with follicular variant papillary thyroid carcinoma, not previously described
