Monoclonal immunoglobulin deposit disease (MIDD) is a rare type of paraproteinemia that is characterized by the presence of monoclonal deposits of immunoglobulins in the basal glomerular membrane, occurring more frequently in the fifth and sixth decade of life. MIDD is subclassified in the disease by light chain deposits (LCDD), heavy chain deposit disease and light and heavy chain deposit disease, with LCDD being the most frequent form of presentation where kappa light chains are identified up to 80 % of cases, and associated to multiple myeloma in up to 50 % of patients. The finding of nodular sclerosis can be associated with LCDD in most patients.

La enfermedad por depósito monoclonal de inmunoglobulina (EDMI) es un tipo raro de paraproteinemia que se caracteriza por la presencia de depósitos monoclonales de inmunoglobulinas en la membrana basal glomerular, manifestándose más frecuentemente en la quinta y la sexta décadas de vida. La EDMI se subclasifica en la enfermedad por depósitos de cadenas ligeras (EDCL), enfermedad por depósitos de cadenas pesadas y enfermedad por depósitos de cadenas ligeras y pesadas. La EDCL es la forma más frecuente de presentación y en ella se identifica cadenas ligeras kappa hasta en el 80 %, asociadas con mieloma múltiple hasta en el 50 % de pacientes. El hallazgo de esclerosis nodular se puede asociar a EDCL en la mayoría de pacientes.

The aim of this study was to describe the frequency of migration to study medicine in Peru. We conducted a secondary data analysis of the Red-LIRHUS study (2011-2012). We included 3 680 Peruvian students. Approximately, 23.2% migrated for medical school. Less than 1% were international migrants. We found a higher proportion of migrant students in Universities outside of Lima than in Universities in Lima (27.1% vs. 15.8%). There was also a higher proportion of migrants in private universities (28.3% vs. 16.0%) Migrant students were more likely to live alone (27.4% vs. 6.4%) and to report having failed a module/course (51.0% vs. 38.6%) compared to non-migrant students. It is necessary to evaluate potential interventions for the preservation of the well-being of people who migrate for their medical training.
