Influence of pancreatic status, CFTR mutations, Staphylococcus aureus and/or Pseudomonas aeruginosa infection/colonization on lung function in cystic fibrosis during a 2-year follow-up period.
Cystic fibrosis (CF) presents with progressive and chronic deterioration of lung function due to inflammation and colonization/infection of the lungs. This study evaluated spirometry and colonization/infection with Staphylococcus aureus and/or Pseudomonas aeruginosa over a 24-month follow-up period. ⋯ In CF, deterioration of lung function as evaluated by spirometry was continuous and varied according to sex, pancreatic insufficiency, and severe CFTR mutations. No differences were observed between groups in terms of predominant type of bacteria, but the reduction of spirometry parameters was significant in the predominantly S. aureus and concomitant infection groups.

Case ReportsLeprosy in a low-incidence setting : Case report relevant to metagenomic next generation sequencing applications.
Leprosy is a disease caused by Mycobacterium leprae that results in disability. In 2000 the World Health Organization announced that leprosy had been eradicated. In nonendemic areas diagnosing leprosy is becoming a challenge for inexperienced clinicians. ⋯ Paraffin-embedded tissue and fresh samples scraped from skin lesions were subjected to in-house PCR targeting 16S rRNA, hsp65, rpoB, rpoT, ribF-rpsO, and mmaA. Sanger sequencing of amplicons from fresh samples and paraffin-embedded tissue verified the presence of M. leprae. For inexperienced clinicians in nonendemic areas nucleic acid amplification tests, such as in-house PCR, are helpful for diagnosing leprosy but sequence reads from metagenomic next generation sequencing may also provide evidence when interpreted cautiously.
