Abstract
Multidrug-resistant bacteria such as Staphylococcus aureus constitute a global health problem. Gram-positive S. aureus secretes various toxins associated with its pathogenesis, and its biofilm formation plays an important role in antibiotic tolerance and virulence. Hence, we investigated if the metabolites of vitamin A1 might diminish S. aureus biofilm formation and toxin production. Of the three retinoic acids examined, 13-cis-retinoic acid at 10 μg/mL significantly decreased S. aureus biofilm formation without affecting its planktonic cell growth (MIC >400 μg/mL) and also inhibited biofilm formation by Staphylococcus epidermidis (MIC >400 μg/mL), but less affected biofilm formation by a uropathogenic Escherichia coli strain, a Vibrio strain, or a fungal Candida strain. Notably, 13-cis-retinoic acid and all-trans-retinoic acid significantly inhibited the hemolytic activity and staphyloxanthin production by S. aureus. Furthermore, transcriptional analysis disclosed that 13-cis-retinoic acid repressed the expressions of virulence- and biofilm-related genes, such as the two-component arlRS system, α-hemolysin hla, nuclease (nuc1 and nuc2), and psmα (phenol soluble modulins α) in S. aureus. In addition, plant and nematode toxicity assays showed that 13-cis-retinoic acid was only mildly toxic at concentrations many folds higher than its effective antibiofilm concentrations. These findings suggest that metabolites of vitamin A1, particularly 13-cis-retinoic acid, might be useful for suppressing biofilm formation and the virulence characteristics of S. aureus.

Abstract
Systemic isotretinoin is commonly used for severe acne treatment. It has many side effects, one of these is about hearing system, which has rarely been reported, also previous studies reported contradictory results about systemic isotretinoin and its association with hearing system. In this study, we aimed to investigate whether systemic isotretinoin affected on the hearing system or not. The study included 32 acne vulgaris patients (64 ears) who treated with oral isotretinoin 0.5 mg/kg body weight for at least 4 months and audiometric tests including pure-tone, speech, bilateral acoustic reflexes, and tympanometric measurements were performed at baseline, in the first week, in the first month, and third month of treatment, and sixth month after treatment. Audiometric tests were performed for right and left ears separately. A significant difference was found in the pure-tone thresholds (before treatment, first week, first month, third month of treatment, and sixth month after treatment) for the both ears at 8000 Hz (P < .001) and a significant decrease in the sixth month post-treatment pure-tone thresholds compared to pre-treatment thresholds at 8000 Hz. Additionally, a statistically significant increase was observed in serum LDL and triglyceride levels in the third month of treatment and a significant decrease at the sixth month after treatment (P < .001). Systemic isotretinoin caused bilateral hearing threshold changes in acne patients during the therapy but the changes improved after discontinuation. Therefore, our findings may provide safety using for dermatologists about hearing effects of isotretinoin, which is quite effective on severe acne.

Abstract
Introduction and Background: Isotretinoin is an oral medication used for the treatment of severe acne unresponsive to other medications. This drug is teratogenic and should be prescribed with appropriate caution in selected group of patients. The washout period for pregnancy post isotrenoin therapy has always been a topic of controversy. Several guidelines have recommended a wash out period of one month if pregnancy is planned in a patient being administered with the drug. Objective: This article discusses the available evidence for different recommended wash out periods and addresses important clinical questions that arise. Methods: Pubmed research was carried out to collect relevant data using the keywords isotretinoin, pregnancy, contraception, pharmacokinetics and guidelines. Conclusion: Our research based on the published data concludes that a wash out period of 35 days post isotretinoin therapy is adequate in routine clinical practice.

Abstract
BACKGROUND To date, there have been no studies that have specifically investigated which medications can and cannot be safely used to treat acne vulgaris in patients who have lupus erythematosus (LE). These patients require a highly individualized treatment approach, as the use of certain acne medications may exacerbate LE symptomology, such as photosensitivity and hypercoagulability. OBJECTIVE In this systematic review, we examine safety outcomes associated with commonly prescribed oral acne medications, specifically in the context of LE. METHODS A literature search, conducted on PubMed/MEDLINE, revealed 146 studies, of which 13 met the criteria. We assigned a level of evidence to each study and sought to determine evidence-based recommendations for each class of drug; each recommendation was then assigned a corresponding grade. RESULTS There were very few high-quality studies available on this topic. Although we determined recommendations based on the existing literature, the grading was occasionally unfavorable due to the low-quality nature of the evidence supporting the recommendation. However, our recommendation against the use of combined oral contraceptive pills and in favor of spironolactone for the treatment of acne, in the setting of LE, received a satisfactory grading (grade A). CONCLUSION While no definitive recommendations for the treatment of acne in LE can be made based on the existing quality and quantity of studies available, this article aims to provide a comprehensive overview and analysis of oral acne medication safety in patients with LE, while emphasizing the immense need for higher quality studies and distinct acne treatment guidelines for this vulnerable patient population.

Abstract
Vitamin A is the first vitamin approved by the Food and Drug Administration as an anti-wrinkle agent that changes appearance of the skin surface and has anti-aging effects. Vitamin A is in a group of fat-soluble substances and belongs to the category of retinoids. Apart from retinol, that group includes structurally related substances with the biological properties of retinol. Since the biological activity of the substances differs, for the purpose of standardization, it is given in retinol equivalents. Vitamin A and its derivatives are among the most effective substances slowing the aging process. Retinoids regulate the cell apoptosis, differentiation and proliferation. Anti-wrinkle properties of retinoids promote keratinocytes proliferation, strengthen the protective function of the epidermis, restrain transepidermal water loss, protect collagen against degradation and inhibit metalloproteinases activity. Retinoid activity is related to high affinity for nuclear receptors: RAR – retinoid acid receptors and RXR – retinoid X receptors.

Abstract
The pathogenesis of inflammatory bowel disease (IBD) is multifactorial and results from an interaction between genetic, immunologic, microbial, and environmental factors. Certain drugs could act as a trigger for the disease and have been implicated in the development of new onset IBD in a number a studies. These relationships are based on case reports and cohort studies, as proving this in the context of randomized controlled trials would be difficult. Drugs that have been linked to causing or worsening IBD include isotretinoin, antibiotics, nonsteroidal antiinflammatory drugs, oral contraceptives, mycophenolate mofetil, etanercept, ipilimumab, and rituximab. Bowel preparation for colonoscopy has also been associated with aphthoid lesions that may be confused with IBD. However, given the source of these reports we have to be cautious in the interpretation of the data before concluding that these drugs trigger IBD and what is being observed is not related to other confounding factors. Different pathogenic mechanisms have been suggested for the different drugs listed above. In order to clarify the confusion a comprehensive literature review was performed with the goal of advancing the knowledge on this subject.

Abstract
Although clinical reports suggest a possible relationship between excess retinoids and the development of depression, the effect of retinoids on mood-related behavior remains controversial. Hyperactivity of the hypothalamus-pituitary-adrenal (HPA) axis plays a key role in the development of affective disorders. The present study aimed to elucidate the effect of retinoid on the activity of HPA axis in rat and whether this goes together with behavioral changes. All-trans retinoic acid (ATRA) was administered to juvenile male rats by daily intraperitoneal injection for 6 weeks. ATRA treatment increased basal serum corticosterone concentration as well as the thickness of adrenal cortex in young rat. Furthermore, the mRNA expression of corticotropin release factor (CRF) and retinoic acid receptor-α (RAR-α) in the hypothalamus was both markedly increased in ATRA-treated rats compared with vehicle. Some behavioral alterations were also observed. ATRA-treated rats showed anxiety-like behavior in elevated-plus maze and decreased spontaneous exploratory activities in novel open field. However, in the sucrose preference test chronic ATRA treatment did not modify behavior in the juvenile animals. Chronic administration of ATRA did not impair physical motor ability in either the prehensile traction or the beam balance/walk test. In conclusion, long-term ATRA administration resulted in hyperactivated HPA axis which was accompanied by several behavioral changes in young rat.

Abstract
The retinoids are a class of compounds that are structurally related to vitamin A. Retinoic acid, which is the active metabolite of retinol, regulates a wide range of biological processes including development, differentiation, proliferation, and apoptosis. Retinoids exert their effects through a variety of binding proteins including cellular retinol-binding protein (CRBP), retinol-binding proteins (RBP), cellular retinoic acid-binding protein (CRABP), and nuclear receptors i.e. retinoic acid receptor (RAR) and retinoid x receptor (RXR). Because of the pleiotropic effects of retinoids, understanding the function of these binding proteins and nuclear receptors assists us in developing compounds that have specific effects. This review summarizes our current understanding of how retinoids are processed and act with an emphasis on the application of retinoids in cancer treatment and prevention.

Abstract
BACKGROUND Cultured hair follicles lacking sebaceous glands do not appear to degrade the inner root sheath (IRS), suggesting that the gland may be involved in this process. OBJECTIVES To examine this supposition in cultured hair follicles. METHODS Pilosebaceous units were isolated from hair follicles cultured in vitro, and IRS degradation was studied by histology. RESULTS When grown in culture, the fibres of follicles lacking sebaceous glands were encased in a layer of translucent tissue. During hair growth in vitro this tissue remained intact at the distal end of the follicle but disappeared further down towards the bulb and then reappeared towards the proximal end. Transection within the region lacking this tissue resulted in the release of a naked hair fibre and the production of hair with no attached tissue upon subsequent hair growth. The translucent tissue represented the IRS, thereby demonstrating that this tissue is indeed degraded in vitro. Histological comparison with freshly isolated pilosebaceous units indicated that IRS degradation in vitro strongly resembled the process that occurs in vivo. CONCLUSIONS These data suggest that the sebaceous gland does not itself participate in IRS degradation. Indeed, this phenomenon appears to be a function of the follicle itself and is probably intimately linked with the processes of cellular proliferation, differentiation and death that occur during hair biogenesis.

Abstract
Acne vulgaris is a common skin condition seen by physicians. It primarily affects adolescents, but can continue into adulthood. A key factor in the pathogenesis of acne is sebum production. Typical therapy includes combinations of topical retinoids and antimicrobials for mild acne, with the addition of oral antibiotics for moderate to severe disease. In the most recalcitrant cases or for nodulocystic acne, oral retinoids are indicated. In women who fail to respond to conventional treatment, hormonal therapy is often used adjunctively. Only isotretinoin and hormonal therapy improve acne via their action on the sebaceous glands. This article focuses on the mechanisms by which these treatment modalities act on the sebaceous glands and their clinical use in the practice of medicine.

Abstract
Male and female Sprague-Dawley rats were orally gavaged with 13-cis-retinoic acid (7.5 or 15 mg/kg) or all-trans-retinoic acid (10 or 15 mg/kg) for 7 consecutive days. Blood was collected out to 8 hr after the last gavage on day 7. HPLC serum concentrations of 13-cis-retinoic acid, all-trans-retinoic acid, and 13-cis-4-oxo-retinoic acid were subjected to model independent pharmacokinetic analyses. Peak serum levels of 563 to 1640 ng/ml were observed for rats treated with 13-cis-retinoic acid at 1.5-2 hr after gavage. Peak serum levels of 183 to 267 ng/ml at 1.5 hr after gavage were observed for all-trans-retinoic acids. The elimination half-life of 13-cis-retinoic acid was about 1.5 hr while the elimination half-life of all-trans-retinoic acid was slightly longer. There were no sex differences for any parameter. Serum levels resulting from the 7.5 mg/kg 13-cis-retinoic acid were similar to those of human Accutane users.

Abstract
Isotretinoin (13-cis retinoic acid (13-cis RA)) is the most potent inhibitor of sebum production, a key component in the pathophysiology of acne, yet its mechanism of action remains largely unknown. The effects of 13-cis RA, 9-cis retinoic acid (9-cis RA), and all-trans retinoic acid (ATRA) on cell proliferation, apoptosis, and cell cycle proteins were examined in SEB-1 sebocytes and keratinocytes. 13-cis RA causes significant dose-dependent and time-dependent decreases in viable SEB-1 sebocytes. A portion of this decrease can be attributed to cell cycle arrest as evidenced by decreased DNA synthesis, increased p21 protein expression, and decreased cyclin D1. Although not previously demonstrated in sebocytes, we report that 13-cis RA induces apoptosis in SEB-1 sebocytes as shown by increased Annexin V-FITC staining, increased TUNEL staining, and increased cleaved caspase 3 protein. Furthermore, the ability of 13-cis RA to induce apoptosis cannot be recapitulated by 9-cis RA or ATRA, and it is not inhibited by the presence of a retinoid acid receptor (RAR) pan-antagonist AGN 193109. Taken together these data indicate that 13-cis RA causes cell cycle arrest and induces apoptosis in SEB-1 sebocytes by a RAR-independent mechanism, which contributes to its sebosuppressive effect and the resolution of acne.

Abstract
Oral treatment with the anti-acne drug Accutane (isotretinoin, 13-cis-retinoic acid) has been associated with suicide ideation and depression. Here, depression-like behaviors (i.e., behavioral despair and anhedonia) were quantified in adult Sprague-Dawley rats gavaged daily beginning at postnatal day (PND) 82 with 13-cis-RA (7.5 or 22.5 mg/kg) or all-trans-retinoic acid (10 or 15 mg/kg ). Tested at PND 130-131 in the Forced Swim Test, 7.5 mg/kg 13-cis-RA marginally decreased immobility and slightly increased climb/struggle durations whereas neither all-trans-retinoic acid group differed from controls. Voluntary saccharin solution (0.03%) intake at PND 102-104 and PND 151-153 was not different from controls in any treated group, although all RA-treated groups had lower intakes. Swim speed in a water maze at PND 180 was similar across groups, indicating no RA-induced differences in physical ability. Open field activity was mildly decreased at PND 91 in 7.5 mg/kg-treated males only, but it was within the control range at PND 119, 147, and 175. Thus, at serum levels similar to those in humans receiving the drug, chronic 13-cis-RA treatment did not severely affect depression-like behaviors in rats. These data do not substantiate the hypothesis of 13-cis-RA-induced depression.

Abstract
Retinoids play a vital role in the treatment of acne because they act on the primary lesion, the microcomedo. They are synthetic derivatives of vitamin A (retinol), and are selected for their effectiveness. Several compounds are used for acne, either in topical or systemic form.We describe and compare the different topical retinoids, tretinoin (all-trans-retinoic acid), isotretinoin (13-cis-retinoic acid), adapalene (derived from naphthoic acid), and tazarotene (acetylenic retinoid). They act mainly as comedolytics, but anti-inflammatory actions have also been discovered recently. The retinoids have great beneficial effects, but also some adverse effects, the main one being teratogenicity. It is preferable not to use them in topical form for pregnant women, although a pregnancy test is only compulsory for tazarotene. Only isotretinoin is used in systemic form. It acts on all the factors of acne and offers long remissions, and sometimes complete cures. Precautions must be taken for women of childbearing age due to its teratogenicity. It is also important to be aware of its other adverse effects, explain them to the patient and, if possible, deal with them in advance.

Abstract
Recent contributions to the understanding of the physiology and biochemistry of sebum production and of the lipids on the skin surface are leading to the development of effective strategies to regulate excessive sebum production and its consequences through the use of cosmetics and skin care products.

Abstract
Despite its potent biologic effect on human sebocytes, 13-cis retinoic acid exhibits low binding affinity for cellular retinoic acid binding proteins and nuclear retinoid receptors. Hence, 13-cis retinoic acid may represent a pro-drug possibly acting through all-trans isomerization. In this study, marked isomerization of 13-cis retinoic acid has been confirmed in cultured SZ95 sebocytes showing 2- to 15-fold higher levels of all-trans retinoic acid at 12-72 h, as measured by high performance liquid chromatography. In contrast, only low amounts of all-trans retinoic acid were converted intracellularly to its 13-cis isoform. 9-cis retinoic acid was not detected after either 13-cis retinoic acid or all-trans retinoic acid treatment. The rapid isomerization of 13-cis retinoic acid to high levels of all-trans retinoic acid was a sebocyte-specific event, as no significant isomerization of 13-cis retinoic acid to all-trans retinoic acid occurred in HaCaT keratinocytes. De novo mRNA expression of cytochrome P450 1A1, a major xenobiotic metabolizing enzyme, in SZ95 sebocytes was induced by all-trans retinoic acid, but not by 13-cis retinoic acid. In addition, mRNA levels of cellular retinoic acid-binding protein II, which is supposed to regulate the concentration of intracellular all-trans retinoic acid, rapidly increased under all-trans retinoic acid treatment (30 min-6 h), whereas the 13-cis retinoic acid effect was markedly weaker and delayed. Both 13-cis retinoic acid and all-trans retinoic acid suppressed mRNA expression of cytochrome P450 1A2. In parallel experiments, 13-cis retinoic acid significantly reduced SZ95 sebocyte proliferation at 10-7 M, show- ing 30-40% inhibition after 9 d. All-trans retinoic acid and 9-cis retinoic acid exhibited similar anti-proliferative effects. AGN 193109, a pan-antagonist of the retinoic acid receptors, antagonized the anti-proliferative activity of all retinoic acid isomers tested in a concentration-dependent manner with complete abolishment at ratios of 1:10 13-cis retinoic acid and 1:1 all-trans retinoic acid. Coincubation of SZ95 sebocytes with 13-cis retinoic acid and AGN 193109 did not alter the intracellular concentration of 13-cis retinoic acid and its isomerization profile. In contrast, the retinoid X receptor antagonist CD 3507 did not affect the inhibition of SZ95 sebocyte proliferation induced by retinoic acids. Our findings indicate: (i) a selective 13-cis retinoic acid isomerization to all-trans retinoic acid in the intracellular compartment of SZ95 sebocytes; (ii) a reduced all-trans retinoic acid inactivation process after 13-cis retinoic acid treatment as compared with treatment with all-trans retinoic acid; and (iii) a retinoic acid receptor-mediated inhibition of SZ95 sebocyte proliferation. These data explain the sebocyte-specific activity of 13-cis retinoic acid and support a pro-drug/drug relation between 13-cis retinoic acid and all-trans retinoic acid.

Abstract
Despite major advances in the molecular biology and pharmacology of retinoids, no new compound has been developed for systemic use. This article addresses some questions related to the indications of oral retinoids already on the market, e.g. isotretinoin, acitretin, as well as tretinoin, reviews some recently reported undesirable effects, and discusses the recent concepts generated by basic research that may lead to new drugs to be used in pharmacology.
