Onychomycosis is a fungal infection of the nail bed, nail plate or both. It is caused by dermatophytes, non-dermatophyte molds and yeast.
Tinea unguium or dermatophytic onychomycosis is a dermatophyte infection of the nail more commonly affecting the toenails than the fingernails.
It is usually asymptomatic and patients first consult for cosmetic reasons.
It is suspected if there are changes in the 3rd or 5th toenail, involvement of the 1st and 5th toenails on the same foot and unilateral nail changes.
Aspergillus colonization may lead to an increase in the risk of bronchiolitis obliterans syndrome. This study determined the impact of colonization of conidia Aspergillus species after post lung transplantation.
No standard currently exists for the growing number of patients with multidrug-resistant strains of Helicobacter pylori, but a recent study has shown the safety and reliability of a 12-day low-dose rifabutin/high-dose proton pump inhibitor (PPI) regimen in patients infected with triple-resistant strains.
Adding rifampicin to standard antibiotic therapy does not improve outcomes in individuals with Staphylococcus aureus (S. aureus) bacteraemia, the ARREST* trial shows. However, rifampicin may contribute towards a minor reduction in bacteraemia recurrence.
Patients with a first episode of Clostridium difficile infection (CDI) are likely to respond to treatment with fidaxomicin with no recurrences, a recent study has shown. On the other hand, those with prior CDI episodes are less likely to respond, especially with >1 prior episode, and more likely to recur, which suggests a greater clinical benefit of fidaxomicin earlier in the course of CDI.
