ABSTRACT
Rectal perforations due to topical treatments (enemas or foams) are unusual complications and they have been mostly reported in the use of barium enemas or in elderly patients with constipation. Very little has been reported about perforations secondary to topical treatment in patients with ulcerative colitis. We present the case of a patient with ulcerative colitis who suffered a rectal perforation complicated with a superinfected collection after the application of topical mesalazine foam.

Gastrointestinal (GI) Endoscopy is a basic competence for the management of gastrointestinal diseases. However, it should not be regarded as an independent training technique. Rather it is a part of a continuous and accredited process that requires clinical knowledge from the gastroenterologist to keep skills up-to-date in a constantly evolving medical subspecialty. Thus, the only official accredited way for training in GI endoscopy is through the Specialized Health Training program in the Management of the Digestive Diseases administered by the Spanish Ministry of Health.

Presentamos el caso de un varón de 67 años que ingresa por cuadro de disnea, lesiones cutáneas violáceas y anemia normocítica a estudio. Durante el ingreso, el paciente es diagnosticado de infección por VIH en fase de SIDA, además de afectación de sarcoma de Kaposi con afectación cutánea, digestiva múltiple (gástrica y rectal) y probablemente pulmonar. El sarcoma de Kaposi es un tumor de origen vascular causado por el virus herpes humano tipo 8. Existen cuatro variantes, nuestro paciente corresponde a la variante relacionada con SIDA. La afectación gastrointestinal cursa con clínica muy variada y la imagen endoscópica es muy característica, pero al tratarse de un tumor de afectación submucosa a veces precisa de biopsia guiada por ecoendoscopia para realizar el diagnóstico. El tratamiento se basa en la terapia antirretroviral y quimioterapia sistémica. (AU)

A 67-year-old man admitted due to dyspnea, violaceous skin lesions and normocytic anemia under study. During admission, the patient is diagnosed with HIV infection in the AIDS phase, in addition to Kaposi's sarcoma with cutaneous, multiple digestive (gastric and rectal) and probably pulmonary involvement. Kaposi's sarcoma is a tumor of vascular origin caused by the human herpes virus type 8. There are four variants, our patient corresponds to the variant related to AIDS. Gastrointestinal involvement presents varied symptoms and the endoscopic image is very characteristic, but as it is a tumor with submucosal involvement, it sometimes requires endoscopic ultrasound-guided biopsy to make the diagnosis. Treatment is based on antiretroviral therapy and systemic chemotherapy.

81 year-old male had an asymptomatic iatrogenic perforation after balloon dilation of esophageal strictures. After the migration of the full covered self expandable metal stent (FCSEMS), a lumen-apposing metal stent (LAMS) was placed and no esophageal leak was seen after. LAMS could be an appropiate first-line approach to benign short esophageal strictures complicated with iatrogenic small perforation but further prospective studies are needed.

To say that someone possesses integrity is to claim that that person is almost predictable about responses to specific situations, that he or she can prudentially judge and to act correctly. There is a closed interrelationship between integrity and autonomy, and the autonomy rests on the deeper moral claim of all humans to integrity of the person. Integrity has two senses of significance for medical ethic: one sense refers to the integrity of the person in the bodily, psychosocial and intellectual elements; and in the second sense, the integrity is the virtue. Another facet of integrity of the person is la integrity of values we cherish and espouse. The physician must be a person of integrity if the integrity of the patient is to be safeguarded. The autonomy has reduced the violations in the past, but the character and virtues of the physician are the ultimate safeguard of autonomy of patient. A field very important in medicine is the scientific research. It is the character of the investigator that determines the moral quality of research. The problem arises when legitimate self-interests are replaced by selfish, particularly when human subjects are involved. The final safeguard of moral quality of research is the character and conscience of the investigator. Teaching must be relevant in the scientific field, but the most effective way to teach virtue ethics is through the example of the a respected scientist.

Alguien íntegro es aquel de quien podemos predecir su comportamiento porque prevemos que juzgará prudentemente la forma de actuar más correcta. La integridad está en estrecha relación con la autonomía, y ésta descansa en el derecho de todos los seres humanos a su integridad como personas. La palabra integridad tiene dos significados en ética médica: por un lado se refiere a la integridad de la persona como totalidad fisiológica, psicológica y espiritual del individuo, y por otro, a la virtud de la integridad. Otra faceta de la integridad de la persona es la que hace referencia a valores que apreciamos y defendemos. Para preservar la integridad de la persona enferma es indispensable un médico que posea la virtud de la integridad. El principio de autonomía ha reducido las violaciones de la integridad de las personas realizadas en el pasado, sin embargo, el carácter y las virtudes del médico son la salvaguarda de la autonomía del enfermo. Una faceta muy importante de la actividad médica es la investigadora. La categoría moral del investigador es lo que determina la calidad moral de la investigación. El problema se plantea cuando los intereses legítimos del investigador son remplazados por el egoísmo, especialmente si la investigación es con sujetos humanos. La salvaguarda final de la calidad moral de la investigación descansa en el carácter y conciencia del investigador. Es muy importante que exista una enseñanza de la ética en el campo de la investigación, pero sobre todo es fundamental el ejemplo ético de científicos respetados y prestigiosos

OBJECTIVE: To assess the value of contrast-enhanced ultrasound in the detection of arterial hypervascularity as a diagnostic criterion of hepatocellular carcinoma (HCC) in patients with focal lesions and liver disease. PATIENTS AND METHODS: This prospective study included patients with chronic liver disease and focal liver lesions on ultrasound (US) examination. SonoVue was used as contrast agent. We employed a US imaging technique with contrast-specific software operating at a low mechanical index (< 0.14) (Hitachi EUB 6500). The contrast enhancement pattern was analyzed during the arterial phase and classified as diffuse (homogeneous or heterogeneous), peripheral, adjacent parenchyma-like enhancement, and absent. The diagnostic procedure was completed by combined study with computed tomography, magnetic resonance imaging, histologic data and clinical features. RESULTS: A total of 23 nodules in 22 patients were included in the study (one patient had two different US lesions). The final diagnosis was hepatocellular carcinoma (HCC) in 12 patients, benign lesions in nine, metastases in one and cholangiocarcinoma in one. In the 10 patients with diffuse contrast enhancement, the lesion was malignant and in the eight patients with diffuse homogeneous enhancement, the lesion was a HCC. Seventy-five percent of the patients with HCC had a diffuse enhancement pattern during the arterial phase. This pattern involved malignancy with 71.4% sensitivity, 100% specificity, 100% positive predictive value, 69.2% negative predictive value, and 82.6% accuracy. The diffuse homogeneous pattern involved HCC with 66.7% sensitivity, 100% specificity, 100% positive predictive value, 73.3% negative predictive value and 82.6% accuracy. CONCLUSIONS: Contrast-enhanced US with SonoVue allows the vascularity of focal liver lesions to be assessed. In our study, 75% of patients with HCC showed arterial hypervascularity. A diffuse homogeneous enhancement pattern during the arterial phase was highly specific to HCC. In cirrhotic patients, this arterial pattern could avoid the need for further investigations, although clinical staging should be completed with another diagnostic test.

Objetivo: Determinar la utilidad de la ecografía con contraste en la detección de hipervascularización arterial como criterio diagnóstico de carcinoma hepatocelular (CHC) en lesiones ocupantes de espacio (LOE) de pacientes con hepatopatía. Pacientes y métodos: Estudio prospectivo en el que se incluyen pacientes con hepatopatía crónica a los que se detectó alguna LOE mediante ecografía. Como potenciador se administró un contraste de segunda generación (SonoVue®). Se utilizó un ecógrafo Hitachi EUB 6500 con un programa específico para potenciadores, y se empleó un índice mecánico inferior a 0,14. Se analizó el patrón de captación en fase arterial, clasificándose en patrón difuso (homogéneo o heterogéneo), periférico, captación similar al parénquima circundante y ausencia de captación. El diagnóstico definitivo se confirmó mediante el estudio combinado de tomografía computarizada, resonancia magnética y análisis histológico, junto con la evolución clínica. Resultados: Se incluyen 23 lesiones en 22 pacientes (uno presentó 2 lesiones de características ecográficas diferentes). El diagnóstico final fue: CHC en 12 casos, lesiones benignas en 9, metástasis en uno y colangiocarcinoma en otro caso. Todos los casos que presentaron un patrón difuso con el contraste tenían una lesión maligna, y los 8 casos con patrón difuso homogéneo tenían un CHC. El 75% de los pacientes con CHC presentó una hipervascularización arterial con un patrón difuso tras el contraste. Este patrón difuso presentó una sensibilidad del 71,4%, especificidad del 100%, valor predictivo positivo (VPP) del 100%, valor predictivo negativo (VPN) del 69,2% y exactitud del 82,6% para el diagnóstico de malignidad. El patrón difuso homogéneo presentó una sensibilidad del 66,7%, una especificidad del 100%, un VPP del 100%, un VPN del 73,3% y una exactitud del 82,6% para el diagnóstico de CHC. Conclusiones: La utilización de la ecografía con contraste de segunda generación facilita una caracterización vascular inmediata de la lesión. En nuestro estudio se detecta una hipervascularización arterial en el 75% de los pacientes con CHC. Un patrón de realce difuso homogéneo es muy específico de CHC. Creemos que la detección de este tipo de patrón en un paciente con cirrosis haría innecesaria la utilización de más pruebas de imagen para el diagnóstico, si bien el estudio de extensión debe completarse con otra técnica
