cutaneous complications caused by a pacemaker or defibrillator are widely documented, but the development of a bronchocutaneous fistula has never been described before. we report the case of a 79-year-old man who was admitted to our hospital because of a seemingly superficial cutaneous infection, externalized defibrillator leads, and hemoptysis. bronchoscopical investigation proved the existenc...

Numerous studies have focused on the influence of the social environment and the interactions between individuals on the collective decision-making of groups. They showed, for example, that attraction between individuals is at the origin of an amplification of individual preferences. These preferences may concern various environmental cues such as biomolecules that convey information about the ...

Traditionally, the progress in science was usually achieved by gradually modifying known problem-solving techniques – so that the modified techniques can solve problems similar to the already-solved ones. Recently, however, a different – successful – paradigm of big data appeared. In the big data paradigm, we, in contrast, look for problems which cannot be solved by gradual modifications of the...

Motivated by an important biomarker study in nutritional epidemiology, we consider the combination of the linear mixed measurement error model and the linear seemingly unrelated regression model, hence Seemingly Unrelated Measurement Error Models. In our context, we have data on protein intake and energy (caloric) intake from both a food frequency questionnaire (FFQ) and a biomarker, and wish t...

Suppose you have to route agents through a network from a source node to a destination node in some optimal way; for instance by minimizing the total travel cost. Nothing new up to now – you could use a standard shortest-path algorithm. Suppose, however, that you want to avoid pure deterministic routing policies in order, for instance, to allow some exploration of the network, to avoid congesti...

Background: Nowadays, drug and observation are advised to patients with lymphocytic hypophysitis and in some cases with nonfunctioning pituitary macoadenoma, instead of surgery. Case presentation: In this article, we report a woman with nonfunctional pituitary macroadenoma and panhypopitutarism and negative criteria for lymphocytic hypophysitis associated with increased liver enzymes. After thr...
