In this paper a series of geochemical investigations are reported with respect to calcium contents in different waters collected from the sea off the coast of Cananéia, the lagoon surrounding Cananéia Island and from Nóbrega river (one of the saline branches from the lagoon, also called "marigot"). An almost direct relation of calcium to chlorinity, 0.02168 in average, similar to that of the outer Atlantic water, 0.02156, was observed in the coastal water. This indicates that the terrigenous supply of calcium might not contribute very much to the calcium content in the coastal water. The inflow of land water to the lagoon of Cananéia does not increase the calcium content of the lagoon water, where a slight depression of the Ca/Cl gradient (namely 0.0206) was observed. This characteristic of the calcium distribution is more remarkable in the water of the "marigot", branching off from the lagoon. An extremely low gradient of calcium to chlorinity, 0.0177 is one of the geochemical characteristics found in tropical estuaries where active bacterial decomposition of deposited organic materials renders the geochemical properties of the water more acid and more reduced. The low content of calcium in land water, 4-6 mg/Ca/kg, has also of course, a close relationship to this peculiar aspect of the calcium distribution in the coastal water, and further in the Atlantic water off the Brazilian coast.

Pericardial Calcification

BackgroundPericardial calcification is seen among patients with constrictive pericarditis (CP). However, the pattern of pericardial calcium distribution and the association with clinical outcomes and imaging data are not well described.MethodsThis was a retrospective study from 2007 to 2013 to evaluate the pattern of pericardial calcium distribution by CT in CP using a semiquantitative calcium scoring system to calculate total pericardial calcium burden and distribution. Calcium localisation was allocated to 20 regions named after the corresponding heart structure. Baseline clinical data, imaging data and clinical outcomes were collected and compared between the calcified pericardium and non-calcified pericardium groups. We assessed the effect of pericardial calcium on clinical outcomes and echocardiographic data between the two groups.ResultsOf the 123 consecutive patients with CP (93 male; mean age 61±13 years) between 2007 and 2013, 49 had calcified pericardium and 74 had non-calcified pericardium. Distribution of calcium on the left ventricle (LV) basal anterior, mid-anterior and apical segments in addition to right ventricle (RV) apical segment was involved in <30% of the cases with the remaining segments involved in >35% of cases. A potential protective role of RV calcium on regional myocardial mechanics was noted.ConclusionPreferential distribution of calcium in CP in a partial band-like pattern (from basal anterolateral LV going inferiorly and then encircling the heart to reach the RV outflow tract) with extension into the mitral and tricuspid annuli was noted. Pericardial calcium was not significantly associated to clinical outcomes.
