Pseudomonas mendocina has been isolated from soil and water samples. Although it has been recovered from some human clinical samples, its pathogenic role has not yet been documented. We report the first known case of endocarditis in humans due to P. mendocina.

The automatic analysis from auto-CPAP (S9 Autoset) showed a good diagnostic accuracy to identify residual sleep apnea. The absolute agreement between PSG and auto-CPAP to classify the respiratory events correctly varied from very low (obstructive apneas, hypopneas) to moderate (central apneas).

These clinical parameters made it possible to indicate CPAP in approximately one third of the population with OSA which would have required it on the basis of their PSG and clinical history. This approach showed high specificity; hence, few patients who did not meet the criteria for CPAP use would have received this treatment.

Excess body iron (Fe) has been proposed to oxidize low ‐density lipoproteins (LDL). Blood samples from 109 non‐institutionalized healthy adults attending Hospital Italiano, Buenos Aires during 2006 were obtained. Samples negative for C‐reactive protein (PCR‐latex, Wiener lab) and risk population were studied: men (M) 23‐95y (n=30) and postmenopausal women (PostW) 51‐83y (n=31). Serum ferritin (SF) (quimiolumminescence analyzer‐ DPC‐Siemmens); unsaturated iron binding capacity (UIBC) (FerroZine‐) (Hitachi 917; automated systems‐ Roche diagnostics) and plasma oxidized LDL (ox‐LDL) (competitive ELISA developed at UNR, School of Biochemical and Pharmaceutical Sciences, Argentina, normal range 2.2‐3.8 U) were measured. Mean values ± SD, (range) and % of individuals with normal values were:No correlation was found between ox‐LDL and SF (r= 0.02) nor UIBC (r=0.006) levels in M and PostW. However, increased risk of chronic diseases may be possible, as wheat flour fortification with Fe is mandatory in Argentina since 2002 in spite of high meat intake (54.7 Kg /capita /y, FAO 2003).
