Este capítulo describe la evolución y los efectos de dos crisis financieras que tuvieron en común una destrucción masiva de liquidez: a saber, la Crisis Rusa de 1998 y la Crisis Financiera Global que se inicia con la quiebra de Lehman Brothers en 2008. La primera golpea fuertemente a las economías emergentes; la segunda, a gran parte de la economía mundial. Con estos episodios, se motiva un análisis más profundo sobre los aspectos comunes acerca de la liquidez y su dinámica. Ello permite extraer lecciones y reflexiones relevantes para la crisis que venimos experimentando desde los inicios de la pandemia de la COVID-19.

We report the case of a two-year-old boy who was admitted at the Instituto Especializado de Salud del Niño in Lima with a diagnosis of intestinal obstruction associated with fifteen days of diarrhea, fever and cough.

Five days later, the eosinophil count reached up to 34,286 cells/mm3. One day later, S. stercoralis larvae were found in a direct stool smear. Serology tests for HTLV-1 and HIV were negative. Interestingly, our patient presented microscopic hematuria and high blood pressure during the highest levels of eosinophils in blood, therefore ...
