FIBRIN BREAKDOWN PRODUCTS: D-dimers are protein substances resulting from the action of 3 enzymes, thrombin, factor XIII and plasmin, on the fibrinogen molecules. In the case of thrombosis, all these enzymatic reactions are activated, explaining the increase in D-dimer levels induced. ⋯ New quantitative tests with latex, based on a turbidimetric method, also appear interesting in this context. The latter is reliable, rapid, inexpensive, remarkably sensitive (97 to 100%) and widely available.

1. AN IMPORTANT RELATIONSHIP: There is a strong relationship between tubular dysfunction, tympanic depression and effusion of the tympanic cavity. 2. TWO IMPORTANT PHENOMENA: Increased secretory capacity of the mucosa and decreased mucociliary clearance subsequent to a reduction in the number of ciliated cells have an important impact. 3. CONTINUUM: Rhinopharyngeal infection, acute middle ear infection and seromucosal otitis constitutes a continuum demonstrated by the fact that PCR (polymerase chain reaction) studies reveal the same germs in the rhinopharynx, in the middle ear fluid, and in seromucous otitis (SMO) effusions. 4.

A COSMOPOLITAN PARASITIC ZOONOSIS: Toxocariasis is a widespread native parasitosis. It is due to the presence of Toxocara-type nematode larvae in the organism, that is at the origin of various clinical pictures. Transmitted by dogs and more rarely by cats, contamination occurs by ingestion of embryos deposited on the ground (animal excrements).
