Metastatic Crohn's disease. Response to adalimumab dose intensification

Inflammatory bowel disease is accompanied by extraintestinal manifestations in a high percentage of patients. Cutaneous lesions are the second most prevalent of these manifestations, and within these, metastatic Crohn's disease is one of the least common, being the least frequent specific cutaneous manifestation of Crohn's disease. This entity includes cutaneous and subcutaneous lesions with a non-caseating granulomatous appearance on histological analysis identical to that of Crohn's disease. These lesions are not found adjacent to the digestive tract. Due to the low prevalence of these manifestations, conclusive trials on the treatment of choice have not been performed and there is no well-defined therapeutic strategy. Distinct therapies with varying results have been reported. We report the case of a female patient with longstanding and complex Crohn's disease who developed metastatic cutaneous manifestations while receiving adalimumab. The cutaneous manifestations responded well to dose intensification of this drug. A review of the literature is provided.     

Automated external defibrillators, life vest defibrillator, or both?

As most understand, survival of cardiac arrest victims falls significantly if cardioversion is not performed promptly. The standard of practice for out-of-hospital defibrillation is the implantable cardiac defibrillator; however, much has been written and discussed about the use of automated external defibrillators. Not as much has been written about life vest wearable defibrillators. How to use these devices will be reviewed in this article.     

Influence of obesity and malnutrition on acute heart failure

Introduction and objectives

Obesity is an independent risk factor for the development of heart failure. Several recent studies have found better outcomes of heart failure for obese patients, an observation termed as the “obesity paradox.” On the other hand, the negative effect of malnutrition on the evolution of heart failure has also been clearly established.

Methods

Data from the Minimum Basic Data Set were analyzed for all patients discharged from all the departments of internal medicine in hospitals of the Spanish National Health System between the years 2006 and 2008. The information was limited to those patients with a primary or secondary diagnosis of heart failure. Patients with a diagnosis of obesity or malnutrition were identified. The mortality and readmission indexes of obese and malnourished patients were compared against the subpopulation without these diagnoses.

Results

A total of 370 983 heart failure admittances were analyzed, with 41 127 (11.1%) diagnosed with obesity and 4105 (1.1%) with malnutrition. In-hospital global mortality reached 12.9% and the risk of readmission was 16.4%. Obese patients had a lower in-hospital mortality risk (odds ratio [OR]: 0.65, 95% confidence interval [95%CI]: 0.62-0.68) and early readmission risk (OR: 0.81, 95%CI: 0.78-0.83) than nonobese patients. Malnourished patients had a much higher risk of dying while in hospital (OR: 1.83 95%CI: 1.69-1.97) or of being readmitted within 30 days after discharge (OR: 1.39, 95%CI: 1.29-1.51), even after adjusting for possible confounding factors.

Conclusions

Obesity in patients admitted for HF substantially reduces in-hospital mortality risk and the possibility of early readmission, whereas malnutrition is associated with important increases in in-hospital mortality and risk of readmission in the 30 days following discharge.Full English text available from:www.revespcardiol.org
