Abstract

Azithromycin is at least as effective as doxycycline in the treatment of moderate acne vulgaris; however, in patients older than 18 years doxycycline is better.

In vitro antibiotic susceptibility patterns of Propionibacterium acnes isolated from acne patients: an Egyptian university hospital‐based study

“…Until the late 1970s, P. acnes was susceptible to different antimicrobials including clindamycin, erythromycin and cyclines 5 . The safe and effective use of azithromycin for treatment of moderate acne vulgaris was also reported 6 . However, with the increased use of antibiotics, the susceptibility trends of P. acnes have gradually changed and varied from one region to another.…”

Severity Assessment and Outcome Measures in Acne Vulgaris

“…The 18 papers that met the inclusion and exclusion criteria [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27] were published across 14 journals, and each represented one RCT, making the number of reviewed RCTs 18. Half of the trials (50 %) were conducted in US or European countries (including a study conducted in the United States, Canada, and Belize and a study in Europe, Mexico, and Australia); the remaining half were conducted in Asian countries.…”

The rate and pattern of Bcl-2 and cytokeratin 15 expression in trichoepithelioma and nodular basal cell carcinoma: A comparative study

“…However, it was previously shown that the basal layer of normal epidermis is usually negative for CK15. [11] Finally, like in any other dermatological pathology, the role of possible confounding factors such the skin type[3435] and age of the patients[36] should be investigated in further studies…”
