Effect of oral anticoagulants on the outcome of faecal immunochemical test.

BACKGROUND: We aimed to evaluate whether oral anticoagulants (OACs) alter faecal immunochemical test (FIT) performance in average-risk colorectal cancer (CRC) screening. METHODS: Individuals aged 50-69 years were invited to receive one FIT sample (cutoff 75 ng ml(-1)) between November 2008 and June 2011. RESULTS: Faecal immunochemical test was positive in 9.3% (21 out of 224) of users of OAC and 6.2% (365 out of 5821) of non-users (P-trend=0.07). The positive predictive value (PPV) for advanced neoplasia (AN) in non-users was 50.4% vs 47.6% in users (odds ratio, 0.70; 95% CI, 0.3-1.8; P=0.5). The PPV for AN in OAC more antiplatelets (aspirin or clopidogrel) was 75% (odds ratio, 2; 95% CI, 0.4-10.8; P=0.4). CONCLUSIONS: Oral anticoagulant did not significantly modify the PPV for AN in this population-based colorectal screening program. The detection rate of advanced adenoma was higher in the combination OAC more antiplatelets.

Epidemiologic study on the current incidence of inflammatory bowel disease in Madrid.

INTRODUCTION: The incidence of inflammatory bowel disease (IBD) varies widely according to geographical area and has been reported to have increased in the last few years. No data are available on the current incidence of this disease in Madrid (Spain). AIM: to determine the incidence of inflammatory bowel disease in the area of influence of University Hospital Fundación Alcorcón (Madrid), and to compare our results with those from other Spanish and European series. PATIENTS AND METHODS: A prospective, population-based study was performed to determine the incidence of IBD in the area of University Hospital Fundación Alcorcón in Madrid between 2003 and 2005. Total population: 213,587 inhabitants (177,490 older than 14 years). Crude rates and age- and sex-specific rates adjusted to the European standard population were calculated. A retrospective study (1998-2003) was also performed. RESULTS: A total of 69 cases were diagnosed -Crohn s disease (CD): 35, ulcerative colitis (UC): 33, indeterminate colitis: 1- in the prospective period. Crude rates of CD and UC were 7.92 and 7.47 cases/100,000 inhabitants/year, respectively (the population aged 0-14 years). Specific rates were 8.0 (95% CI, 7.03-8.97) and 7.47 (95% CI, 6.5-8.4), respectively. Mean age at diagnosis was 31.02+/- 10.76 and 39.91+/-16.19 years for CD and UC, respectively. Incidence in the retrospective study was 7.13 and 6.22 cases/100,000 inhabitants/year, respectively for CD and UC. CONCLUSIONS: The incidence of CD and UC in Madrid has increased in the last decades, with rates close to those in northern European countries for CD, higher than those recently published in Spanish prospective studies and similar to those previously described in Spain and southern countries for UC. Rates were higher in the prospective period than in the retrospective one.

Beneficios de la actividad física sobre aspectos mecánicos óseos: estudio preliminar / Elastic properties of the calcaneus and their variation in populations undergoing physical activity

La actividad física impone cambios en las propiedades elásticas y en la densidad del tejido óseo. Utilizando la densitometría ultrasónica del calcáneo, se comprueba la variación del parámetro BUA (Bone Unit Absortion), expresión de la densidad ósea, en función de la edad de los sujetos y se comprueba la progresión del valor BUA, como en el grupo de estudio y su disminución en el grupo control. Dado que la principal diferencia entre los grupos estudiados era la intensidad de actividad física realizada, y la densidad mejora según el valor BUA en el grupo de estudio, el resultado final de la investigación es coincidente con otros muchos autores que demuestran la utilidad de la actividad física en la mejora y conservación de la densidad ósea

Physical activity impose changes in bone elastic properties and bone mass. Using Ultrasonic densitometry in calcaneus, was studied Bone Unit Absortion (BUA) in population performing or not physical activity, obtaining increasing BUA values in active population and opposites values in non active population. Results of research shows, as well others author, positive aspects in Physical activity as way to improve and maintain bone density (AU)

Diagnostic and therapeutic approach to cholestatic liver disease.

When cholestatic liver disease is present, liver ultrasound should be performed to ascertain if cholestasis is extrahepatic or intrahepatic. If bile ducts appear dilated and the probability of interventional treatment is high, endoscopic retrograde cholagio-pancreatography (ERCP) or trans-hepatic cholangiography (THC) should be the next step. If the probability of interventional therapeutics is low, cholangio-MRI should be performed. Once bile duct dilation and space occupying lesions are excluded, a work up for intrahepatic cholestasis should be started. Some specific clinical situations may be helpful in the diagnostic strategy. If cholestasis occurs in the elderly, drug-induced cholestatic disease should be suspected, whereas if it occurs in young people with risk factors, cholestatic viral hepatitis is the most likely diagnosis. During the first trimester of pregnancy cholestasis may occur in hyperemesis gravidorum, and in the third trimester of gestation cholestasis of pregnancy should be suspected. A familial history of recurrent cholestasis points to benign recurrent intrahepatic cholestasis. The occurrence of intrahepatic cholestasis in a middle-aged woman is a frequent presentation of primary biliary cirrhosis, whereas primary sclerosing cholangitis should be suspected in young males with inflammatory bowel disease. The presence of vascular spider nevi, ascites, and a history of alcohol abuse should point to alcoholic hepatitis. Neonatal cholestasis syndromes include CMV, toxoplasma and rubinfections or metabolic defects such as cystic fibrosis, alpha1-antitrypsin deficiency, bile acid synthesis defects, or biliary atresia. The treatment of cholestasis should include a management of complications such as pruritus, osteopenia and correction of fat soluble vitamin deficiencies. When hepatocellular failure or portal hypertension-related complications occur, liver transplantation should be considered.

Abordaje diagnóstico y terapéutico del síndrome colestásico / Diagnostic and therapeutic approach to cholestatic liver disease

Ante la presencia de colestasis, se debe determinar si su naturaleza es extra o intrahepática. Si la ecografía hepática no muestra dilatación de la vía biliar ni lesiones' ocupantes de espacio, se debe iniciar el estudio de una colestasis intrahepática. Si la obstrucción de la vía biliar extrahepática es cuestionable o la probabilidad de intervencionismo terapéutico es baja, se debe completar el estudio mediante colangio-pancreatografia-RM (CPRM). Si la probabilidad de intervencionismo es alta, se debe realizar colangiopancreatografía retrógrada endoscópica (CPRE) o colangiografía transparieto-hepática (CTPH). En caso de colestasis intrahepática, determinadas situaciones específicas ayudan a orientar el diagnóstico. Si la colestasis intrahepática ocurre en ancianos, se debe sospechar colestasis por fármacos, mientras que en pacientes jóvenes con antecedentes de riesgo, la hepatitis viral es la causa más frecuente. En el primer trimestre del embarazo la hiperemesis gravídica es la causa más probable y en el segundo o tercero la colestasis gravídica. La historia familiar y el curso recurrente deben orientar hacia una colestasis intrahepática recurrente benigna. La presencia de colestasis intrahepática en una mujer de edad media debe hacer sospechar CBP, mientras que en un varón joven con EIIC, una colangitis esclerosante primaria. La presencia de arañas vasculares, ascitis e historia de abuso de alcohol, apuntan hacia una hepatitis alcohólica como causa más probable. En el periodo neonatal, los síndromes colestásicos incluyen infecciones por CMV, toxoplasma, rubeola o defectos metabólicos como la fibrosis quística, el déficit de alfa1-antitripsina, defectos en la síntesis de ácidos biliares o atresia biliar. El tratamiento de la colestasis debe incluir el manejo de complicaciones como el prurito, la osteopenia y el déficit de vitaminas liposolubles. En caso de insuficiencia hepatocelular o complicaciones de la hipertensión portal, el manejo es similar al de otras etiologías y se debe valorar el trasplante hepático (AU)

[Isolated colonic tuberculosis]. / Tuberculosis colónica aislada.

Two cases of colonic tuberculosis (TB) isolated in two elderly, not HIV seropositive women, presenting unspecific clinical manifestations (constitutional syndrome, fever, abdominal pain and diarrhea) and stenosis of the colon in diagnostic imaging techniques are presented. In the second case, endoscopy showed stenosis of the colonic lumen and inflammatory mucosa, the biopsy of which demonstrated granulation tissue with no signs of specificity (in the first case, technical problems did not allow the colonoscopy to reach the affected site). In both cases, diagnosis was performed postoperatively by study of the surgical pieces. Biopsy showed granulomas with acid-alcohol resistant bacilli. Both patients responded favorably to tuberculostatic treatment.
