The Deteriorating Patient: Therapies Including Lung Transplantation.

In this review paper, we discuss the characteristics that define severe bronchiectasis and which may lead to deterioration of noncystic fibrosis bronchiectasis. These characteristics were used to establish the current severity scores: bronchiectasis severity index (BSI), FACED, and E-FACED (exacerbation frequency, forced expiratory volume in 1 second, age, colonization, extension and dyspnea score). They can be used to predict mortality, exacerbation rate, hospital admission, and quality of life.

Dihydropyrimidine dehydrogenase deficiency in patients with severe toxicity after 5-fluorouracil: a retrospective single-center study.

Background: 5-Fluorouracil (5-FU) is an agent frequently used in the treatment of solid cancers. A deficiency in the enzyme that catabolizes 5-FU leads to severe toxicity. The gene responsible for this enzyme is , located on chromosome 1q22.
