Shock séptico secundario a fascitis necrotizante abdominal tras drenaje de absceso interesfintérico perianal / Septic shock secondary to abdominal necrotizing fascitis after drainage of perianal intersphyteric abscess

Resumen Objetivo: El objetivo de este manuscrito es presentar el caso de un varón de 41 años que debuta con shock séptico y fascitis necrotizante abdominal en el posoperatorio del desbridamiento de un absceso perianal para focalizar la atención del lector en la posible evolución clínica hacia gangrena de Fournier. Materiales y Método: Tras la intervención, el paciente refiere aumento de temperatura y sensación de crepitación subcutánea a nivel abdominal, junto con empeoramiento clínico y hemodinámico, evidenciándose evolución tórpida hacia gangrena de Fournier extendida a región abdominal. Resultados: Tras la reintervención, el paciente presentó una evolución favorable aunque requirió sucesivas curas y desbridamientos quirúrgicos. Conclusiones y Discusión: Cabe destacar la importancia de una exploración clínica completa y detallada previa a cualquier intervención quirúrgica, así como el diagnóstico temprano en situaciones de shock séptico que permitan inicio de antibioterapia precoz y control del foco eficaz.

Aim: The objective of this manuscript is to present the case of a 41-year-old man with septic shock and abdominal necrotizing fasciitis after drainage of an interesphinteric perianal abscess to focus the reader's attention on the possible clinical evolution towards Fournier's gangrene. Materials and Method: After the intervention, the patient reported an increase in temperature and a sensation of subcutaneous crepitus at the abdominal level, with clinical and hemodynamic worsening, showing a torpid evolution towards Fournier's gangrene extended to the abdominal area. Results: After the reoperation, the patient presented a favorable evolution, although he required successive cures and surgical debridements. Conclusions and Discussion: It is worth highlighting the importance of a complete and detailed clinical examination prior to any surgical intervention, as well as the early diagnosis in situations of septic shock that allow early initiation of antibiotic therapy and effective control of the focus.

Lagrangian dynamical geography of the Gulf of Mexico.

We construct a Markov-chain representation of the surface-ocean Lagrangian dynamics in a region occupied by the Gulf of Mexico (GoM) and adjacent portions of the Caribbean Sea and North Atlantic using satellite-tracked drifter trajectory data, the largest collection so far considered. From the analysis of the eigenvectors of the transition matrix associated with the chain, we identify almost-invariant attracting sets and their basins of attraction. With this information we decompose the GoM's geography into weakly dynamically interacting provinces, which constrain the connectivity between distant locations within the GoM. Offshore oil exploration, oil spill contingency planning, and fish larval connectivity assessment are among the many activities that can benefit from the dynamical information carried in the geography constructed here.
