RESUMO
Surgical conversion of Roux-en-Y gastric bypass (RYGB) to one anastomosis duodenal switch with sleeve gastrectomy (SADI-S), can be effective, when there is obesity recidivism, but surgically challenging. This case report video aims to detail the technical modifications that simplifies this conversion, in one stage. This video article demonstrates the conversion of RYGB to SADI-S using a jejunal bridge to facilitating the gastro-gastric reconnection. Surgical conversion was done laparoscopically, firstly removing the fundus, gastric body and the proximal part of the antrum. The gastrojejunal (GJ) anastomosis from the previous RYGB was preserved and the jejunal alimentary limb that follows was transected, 8cm distal to the GJ anastomosis, and anastomosed, at this level, with the antrum. The remaining alimentary limb was removed, until the jejuno-jejuno anastomosis, from the previous RYGB. The interposition of a segment of jejunal alimentary limb between the gastric bypass pouch and the antrum, has shown to be safe and feasible in RYGB conversion to SADI-S, without complications. Not reconnecting the remnant jejunal alimentary limb to the intestinal transit, but removing it, makes the procedure shorter and safer.
RESUMO
A paracoccidioidomicose não é uma doença de notificação obrigatória apesar de sua relevância na América Latina, por isso as estimativas de prevalência, incidência e morbidade dessa micose são baseadas em relatórios de levantamentos epidemiológicos, séries de casos, registros de hospitalização e dados de mortalidade. O objetivo desse trabalho foi descrever aspectos relacionados com o paciente, evolução da doença, confirmação diagnóstica e tratamento de casos confirmados de paracoccidioidomicose atendidos em um hospital de ensino do sul do Brasil. Foram coletadas informações de prontuários de 27 pacientes com diagnóstico de paracoccidioidomicose confirmado no período de 2010 até 2019. O perfil prevalente foi de um paciente do sexo masculino, com idade média de 53 anos, envolvido com atividades laborais diversas, de procedência urbana, imunocompetente e sem comorbidades, tabagista, mas não etilista. Para a maioria dos casos o acometimento inicial foi pulmonar, com importante envolvimento do sistema linfático no percurso da doença. A observação microscópica das estruturas fúngicas patognomônicas em amostras de biópsia, aspirado linfonodal e escarro foi o método mais utilizado para confirmar a suspeita clínica. O itraconazol foi a primeira opção de tratamento, seguido da anfotericina B. [au]
Paracoccidioidomycosis is not a notifiable disease despite its relevance in Latin America, so estimates of prevalence, incidence and morbidity of this mycosis are based on reports of epidemiological surveys, case series, hospitalization records and mortality data. The objective of this study was to describe aspects related to the patient, disease evolution, diagnostic confirmation and treatment of confirmed cases of paracoccidioidomycosis treated at a teaching hospital in southern Brazil. Information was collected from the medical records of 27 patients diagnosed with paracoccidioidomycosis confirmed in the period from 2010 to 2019. The prevalent profile was a male patient, with a mean age of 53 years, involved in various work activities, of urban origin, immunocompetent and without comorbidities, smoker, but non-alcoholic. For most cases, the initial involvement was pulmonary, with significant involvement of the lymphatic system in the course of the disease. Microscopic observation of pathognomonic fungal structures in biopsy samples, lymph node aspirate and sputum was the most used method to confirm the clinical suspicion. Itraconazole was the first treatment option, followed by amphotericin B. [au]
RESUMO
Organ dysfunction is a major concern in sepsis pathophysiology and contributes to its high mortality rate. Neutrophil extracellular traps (NETs) have been implicated in endothelial damage and take part in the pathogenesis of organ dysfunction in several conditions. NETs also have an important role in counteracting invading microorganisms during infection. The aim of this study was to evaluate systemic NETs formation, their participation in host bacterial clearance and their contribution to organ dysfunction in sepsis. C57Bl/6 mice were subjected to endotoxic shock or a polymicrobial sepsis model induced by cecal ligation and puncture (CLP). The involvement of cf-DNA/NETs in the physiopathology of sepsis was evaluated through NETs degradation by rhDNase. This treatment was also associated with a broad-spectrum antibiotic treatment (ertapenem) in mice after CLP. CLP or endotoxin administration induced a significant increase in the serum concentrations of NETs. The increase in CLP-induced NETs was sustained over a period of 3 to 24 h after surgery in mice and was not inhibited by the antibiotic treatment. Systemic rhDNase treatment reduced serum NETs and increased the bacterial load in non-antibiotic-treated septic mice. rhDNase plus antibiotics attenuated sepsis-induced organ damage and improved the survival rate. The correlation between the presence of NETs in peripheral blood and organ dysfunction was evaluated in 31 septic patients. Higher cf-DNA concentrations were detected in septic patients in comparison with healthy controls, and levels were correlated with sepsis severity and organ dysfunction. In conclusion, cf-DNA/NETs are formed during sepsis and are associated with sepsis severity. In the experimental setting, the degradation of NETs by rhDNase attenuates organ damage only when combined with antibiotics, confirming that NETs take part in sepsis pathogenesis. Altogether, our results suggest that NETs are important for host bacterial control and are relevant actors in the pathogenesis of sepsis.
