Ischemic colitis due to vigorous physical exercise.

Physical exercise has been related with both beneficial effects on the gastrointestinal tract as with adverse effects on the latter. Gastrointestinal bleeding is one of these. In general, gastrointestinal bleeding is transient and mild. However, some cases caused by intestinal ischemia can sometimes be more serious due to the amount of bleeding and the presence of mucosal lesions. We present the case of a patient with abdominal pain and rectal bleeding caused by an extensive ischemic colitis due to vigorous physical exercise.

[Luetic hepatitis. An emerging entity]. / Hepatitis luética. Una entidad emergente.

Liver involvement is unusual in the course of syphilitic infection. We present four cases of luetic hepatitis diagnosed at our hospital in the last 5 years. One patient was coinfected with hepatitis B virus and another patient was coinfected with hepatitis C virus and HIV. The presence of maculopapular skin lesions in palmoplantar distribution, as well as serological confirmation, were decisive for the diagnosis of syphilitic hepatitis, allowing early antibiotic therapy to be established, with clinical and analytical improvement in all patients. Luetic hepatitis should be considered in patients with risky sexual behavior, skin lesions and altered liver function tests with a predominance of cholestasis, despite the finding of other, more frequent, liver diseases, given that these entities may be concurrent. Early diagnosis of syphilis leads to effective treatment of the patient and to epidemiological control of the infection.

Colonic Metastases From Lung Carcinoma: A Case Report and Review of the Literature.

Lung cancer is the most frequent cause of cancer death in the world. Although about 50% of lung cancers have distant metastases at the time of diagnosis, gastrointestinal metastasis has rarely been described. The most common metastatic site is the small bowel, whereas, colonic metastases are very rare. This report presents a clinical case of a 68-year-old male with a previous diagnosis of non-microcytic lung carcinoma (T4, N2, M1), stage IV, who presented rectorrhagia at the emergency. Colonoscopy showed many ulcerated tumors along the colon and histology proved that these lesions were metastases of primitive lung carcinoma. Gut metastasis from the lung is uncommon but we have to be aware of it in patients who present gastrointestinal symptoms.

Hepatitis luética. Una entidad emergente / Luetic hepatitis. An emerging entity

La afectación hepática por sífilis es infrecuente. Se exponen 4 casos de hepatitis luética diagnosticados en los últimos 5 años. Uno presentaba coinfección por virus de la inmunodeficiencia humana y virus de la hepatitis C, y otro por virus de la hepatitis B. Las lesiones cutáneas maculopapulosas de extensión palmoplantar y la confirmación serológica fueron determinantes para llegar al diagnóstico. Ante el aumento de incidencia de las enfermedades de transmisión sexual, entre ellas la sífilis, es importante tener en cuenta el diagnóstico de hepatitis luética en aquellos pacientes que presentan hábitos sexuales de riesgo y alteración de pruebas de función hepática con predominio de colestasis, y no conviene descartarla a pesar del hallazgo de otras enfermedades hepáticas más frecuentes, dado que pueden coexistir. El diagnóstico precoz de la sífilis conduce a un tratamiento eficaz para el individuo y para el control epidemiológico de la infección(AU)
