Parasitic rheumatism is a rare condition characterized by inflammatory joint manifestations due to a parasitic infestation without parasites into joint cavity, (but, with circulating immune complexes, in serum, and synovial fluid; and with immunoglobulins and complement deposits in synovium in some cases reported in the literature). The number of parasites (now 15) which can induce such an arthritis by immune mechanisms is steadily increasing. In all, but few cases of parasitic rheumatism, usual parasitic manifestations (diarrhea, abdominal pain, nausea...) are mild or absent; but, if present, they are a very good criteria to evoke the diagnosis. Clinical pictures of arthritis induced by parasitic infestation are very polymorphic, and non specific of the involved parasite; they seem to depend on genetic predisposition: the symptoms are monoarticular, pauciarticular, or polyarticular, involving small, medium, and or large joints. They can mimic the clinical picture of different inflammatory rheumatic diseases. The most striking feature of parasitic rheumatism is the failure of antirheumatic agents (especially non steroidal anti-inflammatory agents), contrasting with the dramatic efficacy of specific anti-parasitic treatment. The proof of the responsibility of parasitic infestation by indirect mechanism is given by an exceptional case report of a patient with arthritis, dramatically cured after removal of larvae from Anisakiasis gastric granuloma. To explain the uncommon occurrence of this variety of reactive arthritis, due to parasitic infestation, despite the high prevalence of parasitic infestation in the world, hypothesis of genetic predisposition seems valuable. Among 34 well documented reported cases of parasitic rheumatism in the literature, HLA B 27 antigen has been researched in 13; out of these 13, HLA B 27 is absent in 9; in 7 out of these 9, clinical picture is symmetrical polyarthritis. Out of the 13 cases, HLA B 27 is present in 4: In all these 4 cases, clinical picture is asymmetrical pauciarthritis, mimicking arthritis of Reiter's disease.

Whole-tree water use in 4- and 8-year-old plantations of Eucalyptus nitens Deane and Maiden (ex Maiden) in the presence and absence of Acacia dealbata Link. weeds was estimated by the heat pulse velocity technique during a six-week summer period. Maximum sap velocities were recorded between 5 and 15 mm under the cambium for both eucalypt and acacia trees, and marked radial and axial variations in sap velocity were observed. The latter source of variation was most pronounced in mixed stands where crowns were asymmetrical. Mean daily sap flux ranged from 1.4 to 103.6 l day(-1) for eucalypts and from < 0.1 to 8.4 l day(-1) for acacias. Stem diameter explained 98% of the variation in sapwood area for E. nitens and 89% for A. dealbata, and was determined to be a suitable parameter for scaling water use from the tree to stand level. Plot transpiration varied from 1.4 to 2.8 mm day(-1) in mixed 8-year-old plots and was 0.85 mm day(-1) in a mixed 4-year-old plot. The degree of A. dealbata infestation was associated with absolute plot water use and regression models predicted that, in the absence of acacia competition, plot water use for the 8-year-old stand would approach 5-6 mm day(-1) during the growing season.
