Metástasis cutánea metacrónica de carcinoma escamoso de canal anal / Methachronical cutaneous metastasis of squamous carcinoma of the anal canal / Metástase cutânea metacronica de carcinoma escamoso do canal anal

El tratamiento correcto de carcinoma escamoso avanzado requiere de un manejo multidisciplinar entre cirujanos, anatomopatólogos, radioterapeutas y radiólogos. Los protocolos están claros cuando nos hallamos ante una enfermedad localizada, sin embargo, cuando la enfermedad es metastática no existe evidencia científica de los pasos a seguir. Presentamos una paciente con un carcinoma escamoso del ano con una única metástasis cutánea metacrónica que fue tratada con cirugía y radioterapia posterior con buena respuesta.

The right therapy of anal cancer needs a multidisciplinary management of surgeons, pathologists, radiotherapists and radiologist. The treatment of squamous cell carcinoma of the anal canal is well-known when the patient presents a locally disease, nevertheless, there is a lack of information with the advanced anal cancer. We report a case of a 74-year-old woman with a solitary methachronical cutaneous metastasis of anal cancer which responded perfectly to surgery and radiotherapy.

A correta terapêutica do câncer anal necessita de uma gestão multidisciplinar de cirurgiões, patologistas, radio terapeutas e radiologistas.O tratamento do carcinoma espinocelular do canal anal é bem conhecido quando o paciente apresenta uma doença local, porém, há uma falta de informação sobre o câncer anal avançado. Relatamos o caso de uma mulher de 74 anos com metástase cutânea metacrônica solitária de câncer anal que respondeu perfeitamente à cirurgia e à radioterapia.

Isquemia aguda del canal anal / Acute Ischemia of the Anal Canal

Introducción: La isquemia anal aguda con gangrena es una entidad infrecuente, con escasa literatura publicada al respecto, cuyas cifras de mortalidad descritas se sitúan en un 20 por ciento - 40 por ciento de los casos. Debe considerarse en ancianos con enfermedad aterosclerótica que presenten síntomas gastrointestinales inferiores y shock hipotensivo. Puede ser causada por oclusión vascular aguda, enfermedad vascular grave o un estado de bajo flujo, aunque en algunos casos se presenta sin enfermedad vascular preexistente. Objetivo: Presentar la literatura existente acerca del manejo diagnóstico y terapéutico de la isquemia de canal anal en base a un caso clínico diagnosticado y tratado de urgencia en el hospital "Marina Baixa". Caso clínico: Se presenta un caso de isquemia espontánea de canal anal en paciente de 76 años de edad con morbilidad cardiovascular asociada. Debuta como cuadro séptico sin evidencia de causa desencadenante. Conclusiones: Las pruebas endoscópicas y radiológicas deben realizarse con urgencia y la valoración quirúrgica está siempre justificada en estos pacientes debido a la alta tasa de mortalidad descrita en el manejo conservador del cuadro. En casos graves, la reanimación preoperatoria y cirugía urgente para resecar el segmento gangrenoso es necesaria. Sin embargo, el tratamiento de la proctitis isquémica aguda es controvertido y depende, en parte, del estado basal del paciente y los hallazgos clínicos, siendo importante examinar otras posibles etiologías de proctitis isquémica y así determinar qué pacientes necesitan intervención quirúrgica temprana en comparación con una actitud más conservadora(AU)

Introduction: Acute ischemic gangrene of the anus is an infrequent entity, with little published literature, whose reported mortality figures are 20-40 percent of cases. It should be considered in elderlies with atherosclerotic disease who present lower gastrointestinal symptoms and hypotensive shock. It can be caused by acute vascular occlusion, severe vascular disease, or a low-flow state, although in some cases it presents without pre-existing vascular disease. Objective: To present the existing literature on diagnostic and therapeutic management of ischemia of the anal canal upon the base of a clinical case diagnosed and treated as an urgency at Marina Baixa hospital. Clinical case: The case is presented of a 76-year-old patient with spontaneous ischemia of the anal canal and associated cardiovascular morbidity. It debuts as a septic condition without evidence of a triggering cause. Conclusions: Endoscopic and radiological tests should be performed urgently. Surgical assessment is always justified in these patients, due to the high mortality rate described in the conservative management of the condition. In severe cases, preoperative resuscitation and urgent surgery to resect the gangrenous segment is necessary. However, managment of acute ischemic proctitis is controversial and depends, in part, on the patient's baseline status and clinical findings, while it is important to examine other possible etiologies of ischemic proctitis and thus determine which patients need early surgical intervention compared to a more conservative attitude(AU)

Usefulness of infection biomarkers for diagnosing bacteremia in patients with a sepsis code in the emergency department.

The objective of this study was to assess the usefulness of the biomarkers lactate, C-reactive protein (CPR) and procalcitonin for the diagnosis of bacteremia in patients with suspected sepsis in the emergency department (ED) and according to the focus of infection. We conducted a retrospective study among patients included in the sepsis code of our ED between November 2013 and December 2017. We analyzed demographic variables, co-morbidity according to the Charlson Index and focus of infection, blood cultures and classification according to Gram staining. We determined the diagnostic performance of the biomarkers quantitatively and calculated the area under the curve (AUC) for global bacteremia and as a function of the focus of infection. We included 653 patients with a median age of 79 years (interquartile range: 66-86), of whom 287 (44.0% were women. The most frequent infectious focus was respiratory (36.1%]. Blood cultures were requested in 87.5% (569 cases). Of the tested samples, 31.3% were positive, of which 63.5% revealed Gram-negative (GN) bacteria. Procalcitonin obtained globally the best AUC 0.70 (95% CI: 0.65-0.75). The values with the best sensitivity and specificity were 2.54 ng/mL for procalcitonin, 4.1 mmol/L for lactate and 156 mg/L for CRP. We found an association between the median procalcitonin value and GN bacteria (6.02; IQR: 1.39-39.40) and Gram-positive bacteria (1.74; IQR: 0.22-15.61). Procalcitonin is the biomarker with the greatest capacity to diagnose bacteremia, particularly in GN infection. Stratification by focus is important since not all biomarkers discriminate in the same way.
