First time identification of Pandoraea sputorum from a patient with cystic fibrosis in Argentina: a case report.

Background: Pandoraea species are considered emerging pathogens in the context of cystic fibrosis (CF) and are difficult to identify by conventional biochemical methods. These multidrug resistant bacteria remain poorly understood particularly in terms of natural resistance, mechanisms of acquired resistance and impact on the prognosis of the disease and the lung function. Among them, Pandoraea sputorum has been previously described in few cases of CF patients from Spain, Australia, France and United States, underlining the need of more clinical data for a better knowledge of its pathogenicity.

Pharmacotherapy in the extreme longevity.

The increased longevity brings to the appearance of more polypathologies, being frequently of chronic-degenerative type, and also an increased use of pharmaca. The present study evaluated the usual drug consumption in the ultralongevous people in comparison with their clinical conditions. A total of 602 centenarians were involved: clinical anamnesis, objective examinations and clinico-functional evaluations were performed.

C4, BF, C3 allele distribution and complement activity in healthy aged people and centenarians.

The aim of this study was to examine the complement system and the distribution of some human leukocyte antigen (HLA) class III alleles (C4, BF) in healthy aged people (77 centenarians and 89 elderly subjects). We have also studied the alleles of C3, a complement component genetically unrelated to HLA, the immunochemical levels of C4 and C3 and serum functional hemolytic activity for classical (CH50) and alternative (AP50) complement pathway. The levels of C3 and C4 and the CH50 and AP50 were found to be within the normal range.
