Pityriasis (Tinea) versicolor is a fungal infection caused by Malassezia furfur. It is benign, superficial, and localized to the stratum corneum.
It may present as chronic or recurrent infection and may occur in healthy individuals.
It is more common in summer than winter months.
It presents with multiple well-demarcated macules or patches and finely scaled plaques with hypopigmentation or hyperpigmentation, hence the term "versicolor".
Lesions are usually found on the upper trunk, chest, back and shoulders, and may extend toward the neck, face and arms.
The combined use of piperacillin and tazobactam does not appear to be a suitable alternative to meropenem for patients with bloodstream infections caused by ceftriaxone-resistant Escherichia coli (E. coli) or Klebsiella pneumoniae (K. pneumoniae), according to results of the MERINO* trial.
The addition of low oxygen levels measured by pulse oximetry to the three signs delineated in the current diagnostic model for pneumonia in primary care setting derived by van Vugt, which include fever, tachycardia, and crackly breath sounds on auscultation, can add value to diagnostic precision and help general practitioners (GPs) differentiate pneumonia from less serious infections, a study suggests.
Ceftazidime-avibactam appears to offer a reasonable alternative to colistin in the treatment of Klebsiella pneumoniae carbapenemase (KPC)-producing carbapenem-resistant Enterobacteriaceae (CRE) infections, according to a study.
