BACKGROUND/AIM: Systemic isotretinoin has been widely considered an effective and safe medical treatment for severe and refractory acne for nearly 3 decades. However, it also appears to cause undesirable cutaneous side effects. The aim of this study was to prospectively measure biophysical parameters of skin function among patients with acne vulgaris before and after 3 months of isotretinoin therapy, including pH, temperature, sebum content, skin hydration, and transepidermal water loss...

Tretinoin is known to be a pharmaceutical drug for treating acne vulgaris, keratosis pilaris, and acute promyelocytic leukemia. In order to reveal the possible conformers of tretinoin, the energies of all the conformers through rotational bonds have been evaluated by systematic rotor search analysis. The intramolecular interactions ranging from strong hydrogen bonds to weak van der Waals forces present in tretinoin have been distinguished with the help of electron density mapping and wavefunction analysis. The global reactivity descriptors and Fukui functions of tretinoin have been calculated and discussed...

REVIEW
Suzana Saric, Manisha Notay, Raja K Sivamani
Polyphenols are antioxidant molecules found in many foods including nuts, fruits, vegetables, chocolate, wine, and tea. Polyphenols have antimicrobial, anti-inflammatory, and antineoplastic properties. Recent studies suggest that tea polyphenols may be used for reducing sebum production in the skin and for treatment of acne vulgaris. This review examines the evidence for use of topically and orally ingested tea polyphenols against sebum production and for acne treatment and prevention. The PubMed database was searched for studies on tea polyphenols, sebum secretion, and acne vulgaris...

Qi Su, Maria Grabowski, Günther Weindl
Propionibacterium acnes has been considered as a crucial contributor to the pathogenesis of acne vulgaris. The interaction between P. acnes and the host is mainly mediated by Toll like receptor (TLR) 2 recognition. TLR2 homodimers recognize P. acnes in mice, but here we describe the prerequisite of TLR2/1 and TLR2/6 heterodimers in human cells for P. acnes recognition. P. acnes-induced NF-κB and AP-1activation observed in HEK hTLR2-transfected but not control cells confirmed the specificity of TLR2 recognition...

Dapsone 7.5% gel (Aczone(®)) is indicated for the once-daily topical treatment of acne vulgaris in patients aged ≥12 years. Dapsone is a sulfone antibacterial with anti-inflammatory actions, which are thought to be largely responsible for its efficacy in treating acne vulgaris. In two phase III trials of 12 weeks' duration in patients aged ≥12 years with moderate acne vulgaris, once-daily dapsone 7.5% gel reduced acne severity (as per the Global Acne Assessment Score) and lesion counts versus vehicle...

REVIEW

Dimethoxycurcumin (DiMC) is a synthetic analogue of curcumin with superior inter-related pro-oxidant and anti-cancer activity, and metabolic stability. Numerous studies have shown that DiMC reserves the biologically beneficial features, including anti-inflammatory, anti-carcinogenic and cytoprotective properties, almost to the same extent as curcumin exhibits. DiMC lacks the phenolic-OH groups as opposed to curcumin, dimethoxycurcumin, and bis-demethoxycurcumin that all vary in the number of methoxy groups per molecule, and has drawn the attentions of researchers who attempted to discover the structure-activity relationship (SAR) of curcumin...

Der übermäßige oder unkritische weltweite Einsatz von Antibiotika in der Medizin hat die Ausbreitung von Antibiotikaresistenzen beschleunigt. In einigen Bereichen sind viele Antibiotika bei bakteriellen Infektionen, die zuvor noch gut auf antibakterielle Wirkstoffe reagierten, mittlerweile wirkungslos geworden. Dermatologen/Venerologen setzten orale und topische Antibiotika bei der Behandlung von Acne vulgaris routinemäßig ein, obwohl Akne weder eine infektiöse Erkrankung ist noch alleine durch das Propionibacterium getriggert wird...

BACKGROUND: Minocycline, a broad-spectrum antibiotic from the group of tetracyclins, is frequently prescribed for acne vulgaris and rosacea. Hyperpigmentation is a relatively common side effect of this drug and can lead to multiple unsightly skin lesions, which are not always reversible. It can take a long period, from a few months to several years, before the lesions have completely vanished. CASE DESCRIPTION: A 24-year-old male was seen in our outpatient clinic because of slowly progressive pigmented lesions on his shins...

Acne vulgaris is a common skin problem affecting nearly 90% of adolescents and its development is associated with a colonization of Propionibacterium acnes (P. acnes). Although antibiotics have commonly been used to treat acne, antibiotic resistance of P. acnes is an emerging issue to be solved. In this study, a new way of photodynamic acne therapy is developed using P. acnes lipase-sensitive transfersome (DSPE-PEG-Pheo A (DPP) transfersome). For enhanced selectivity and skin penetration efficiency, DPP transfersomes are prepared from 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-[amino(polyethylene glycol)-2000], pheophorbide A (Pheo A), cholesterol, and Tween-80...
