Instead of a cooler, Gary Cunningham’s new set of lungs arrived at UPMC Presbyterian in a high-tech box on wheels. The small machine kept the donor lungs functioning and “breathing” outside the body with a constant supply of blood and nutrients. The machine, made by Massachusetts-based TransMedics, allows the lungs to remain at a normal body temperature [1, 4]. It was one of the first case of using mechanical perfusion in normothermia for lung storage before transplanting. There are similar researches in kidney and liver transplantation. Read full text »
Tuberculosis is a common human and animal infectious disease occurring worldwide caused by Gramm positive acid-fast bacteria. The most dangerous for people are typical strains Mycobacterium tuberculosis and Mycobacterium bovis. Every year around 8-9 mln of new cases are reported and 2 million people dies because of the infection and its complication. This places tuberculosis on the top of the leading infectious diseases, with regard to morbidity and mortality worldwide. Despite the fact that BCG vaccines are available, the situation is very serious because there are many problems i.a. difficulties in detecting myobacteria and its multidrugresistance .

If you are dealing with parents desperately wanting their offsprings free from sneezing and cough, advise them to buy a cat or a dog! According to the article (1) by Finnish specialists, published in the July issue of Pediatrics journal, keeping furry animals contributes to the lower rate of respiratory infections in the child’s first year of life. Better resistance to microbes might be explained by the enhanced maturation of the immune system, which is presumably provoked by the exposure to antigens carried by animals. Various studies have already tested this hypothesis, but the results were often opposing. This time European researchers try to convince us one more time that, as far as children are concerned, the more dirt the better.
