Review
OBJECTIVE
We conducted a review of topical agents currently used in melasma, discussing their mechanism of action, efficacy, safety, and tolerability, with an update on newer treatments.
METHODS
A systematic review from PubMed database was performed, using PRISMA guidelines. The search was limited to English and Spanish studies that were double or single blinded, prospective, controlled or randomized clinical trials, reviews of literature, and meta-analysis studies.
RESULTS
348 studies were analyzed; 80 papers met inclusion criteria. Triple combination (TC) therapy and hydroquinone (HQ) are still the most well-studied agents with strong evidence-based recommendation. TC therapy remains the gold standard of care based on efficacy and patient tolerability. Evidence has shown ascorbic acid, azelaic acid, glycolic acid, kojic acid, salicylic acid, and niacinamide to be effective as adjuvant therapies with minimal side effects. Tranexamic acid (TA) and cysteamine have become recent agents of interest due to their good tolerability, however more trials and studies are warranted. Less evidence exists for other topical agents, such as linoleic acid, mulberry extract oil, rucinol, 2% undecylenoyl phenylalanine, and epidermal growth factors agents.
LIMITATIONS
Some studies discussed represented a low sample size, and there is an overall lack of recent studies with larger populations and long-term follow up.
CONCLUSIONS
TC therapy continues to be the gold standard of care. Topical cysteamine and TA are newer options that can be incorporated as adjuvant and maintenance treatments into a patient's regimen. Cysteamine and topical TA have no known severe adverse effects. Evidence comparing other topical adjuvant treatments to HQ, maintains HQ as the gold standard of care.

Review
Since their introduction, topical corticosteroids have become indispensable in the treatment of various dermatoses. Hydrocortisone was the first compound. Modifications in the basic structure generated in vivo activity and thus different topically active compounds were discovered. Apart from the Stoughton vasoconstrictor assay, various other methods are used for potency assessment of topical corticosteroids. Topical corticosteroides are classified based upon potency and action of these molecules. Mechanism of action at the cellular level and indications of topical corticosteroid use have been discussed. Various adverse effects often occur as an extension of their activity combined with inappropriate usage. Tachyphylaxis and contact allergy are potential problems in clinical practice. Newer compounds with improved risk-benefit ratio are available.

Review
Uveitis maybe induced by the use of various medications known as drug-induced uveitis (DIU), though rare it is an important cause of uveitis which one needs to be aware of. The drugs may be administered through any route including systemic, topical, and intravitreal. Ocular inflammation can be in the form of anterior, intermediate, posterior or pan uveitis, and rarely may present as episcleritis and scleritis. Identification of drug as the offending agent of uveitis is important as many a times stopping the drug may help recover the uveitis or the concomitant use of corticosteroids. An extensive literature review was done using the Pubmed. An overview of DIU is provided as it is important for us to be aware of this clinical entity.

Review
The comprehensive treatment of pain is multidimodal, with pharmacotherapy playing a key role. An effective therapy for pain depends on the intensity and type of pain, the patients' age, comorbidities, and appropriate choice of analgesic, its dose and route of administration. This review is aimed at presenting current knowledge on analgesics administered by transdermal and topical routes for physicians, nurses, pharmacists, and other health care professionals dealing with patients suffering from pain. Analgesics administered transdermally or topically act through different mechanisms. Opioids administered transdermally are absorbed into vessels located in subcutaneous tissue and, subsequently, are conveyed in the blood to opioid receptors localized in the central and peripheral nervous system. Non-steroidal anti-inflammatory drugs (NSAIDs) applied topically render analgesia mainly through a high concentration in the structures of the joint and a provision of local anti-inflammatory effects. Topically administered drugs such as lidocaine and capsaicin in patches, capsaicin in cream, EMLA cream, and creams containing antidepressants (i.e., doxepin, amitriptyline) act mainly locally in tissues through receptors and/or ion channels. Transdermal and topical routes offer some advantages over systemic analgesic administration. Analgesics administered topically have a much better profile for adverse effects as they relieve local pain with minimal systemic effects. The transdermal route apart from the above-mentioned advantages and provision of long period of analgesia may be more convenient, especially for patients who are unable to take drugs orally. Topically and transdermally administered opioids are characterised by a lower risk of addiction compared to oral and parenteral routes.

Review
INTRODUCTION
Microneedling (MN) is a minimally invasive procedure involving the induction of percutaneous wounds with medical-grade needles. In this literature review, we investigate clinical data on MN for the treatment of hair loss disorders.
METHODS
A literature search was conducted through PubMed up to November 2021 to identify original articles evaluating the use of MN on hair loss disorders. The database was searched using the following keywords: "microneedling," "micro needling," "micro needle," "microneedle," "needle," "dermaroller" and "alopecia," "hair loss," "alopecia," "areata," "cicatricial," or "effluvium," RESULTS: A total of 22 clinical studies featuring 1127 subjects met our criteria for inclusion. Jadad scores ranged from 1 to 3, with a mean of 2. As an adjunct therapy, MN improved hair parameters across genders and a range of hair loss types, severities, needling devices, needling depths of 0.50-2.50 mm, and session frequencies from once weekly to monthly. Across 17 investigations totaling 911 androgenic alopecia (AGA) subjects, MN improved hair parameters when paired with 5% minoxidil, growth factor solutions, and/or platelet-rich plasma (PRP) topicals, or when introduced to subjects whose hair count changes had plateaued for ≥ 6 months on other treatments. Across four investigations on 201 alopecia areata (AA) subjects, MN improved hair parameters as a standalone therapy versus cryotherapy, as an adjunct to 5-aminolevulinic acid and photodynamic therapy, and equivalently when paired with topical PRP versus carbon dioxide laser therapy with topical PRP. Across 657 subjects receiving MN, no serious adverse events were reported.
CONCLUSIONS
Clinical studies demonstrate generally favorable results for MN as an adjunct therapy for AGA and AA. However, data are of relatively low quality. Significant heterogeneity exists across interventions, comparators, and MN procedures. Large-scale randomized controlled trials are recommended to discern the effects of MN as a standalone and adjunct therapy, determine best practices, and establish long-term safety.

Review
Atopic dermatitis (AD) is a chronic inflammatory skin condition that can have tremendous impact on quality of life for affected children and adults. First-line therapy for acute management of AD includes topical therapies such as corticosteroids, calcineurin inhibitors, and, more recently, the phosphodiesterase inhibitor crisaborole. Topical agents have remained the mainstay therapy for decades; however, there has been a longstanding need for topical therapies with high efficacy and low risk of adverse effects with long-term use. Given the ongoing advances in understanding the pathogenesis of AD, there are novel targets for pharmacological intervention. We are now in an unprecedented time with more than 40 topical treatments in the pipeline for AD in addition to many developments and treatments on the horizon. This review summarizes selected therapeutic topical agents in later phases of development that target various aspects in the pathogenesis of AD such as Janus kinase inhibition (ruxolitinib and delgocitinib), phosphodiesterase-4 inhibition (roflumilast and difamilast), aryl hydrocarbon modulation (tapinarof), and modulation of the microbiome. We also review novel targeted therapies that are in early phase clinical trials, including AMTX-100, BEN-2293, and PRN473. Preliminary findings on efficacy and tolerability of most of these agents are promising, but further studies are warranted to evaluate the long-term safety and efficacy of these novel agents against the current standard of care.

Review
Recent studies have shown that low-dose oral minoxidil (OM) can be a safe and effective treatment of numerous hair disorders including male-patterned hair loss (MPHL) and female-patterned hair loss (FPHL). There are several practical advantages of OM over its topical formulation: enhanced cosmesis, cost-savings, and the possibility of co-therapy with other topical formulations or topicals used for camouflage. This treatment may be particularly helpful for patients who are unable to tolerate topical minoxidil or other systemic treatments. Doses ranging from 0.25 to 1.25 mg daily are usually used for FPHL and doses ranging from 2.5 to 5 mg/day for MPHL. The low side-effect profile of low-dose OM allows for long-term adherence to the medication and favorable clinical response, resulting in stabilization and improvement of hair loss. More studies are needed to test the efficacy of OM in other types of alopecia as well as additional comparative studies assessing OM to other commonly used medications.

Review
Ageing, a basic biological process seen in all living creatures, is not preventable. Surgical and topical modalities have been invented and substances were applied topically to alter the ageing process. Peptides and proteins, frequently used for this purpose, were categorized into four groups: signal peptides, enzyme-inhibitor peptides, neurotransmitter-inhibitor peptides and carrier peptides. We comprehensively review eligible studies -including controlled ex vivo or in vivo efficacy studies on any topical peptide or protein that has been administered to treat signs and symptoms of ageing.

Review
Striae distensae (SD) are common dermal lesions, with significant physical and psychological impact. Many therapeutic modalities are available but none can completely eradicate SD. The most common therapy is the application of topicals used both therapeutically and prophylactically. Even though there are many commercially available topical products, not all have sufficient level of evidence to support their continued use in SD. The aim here was to assess the evidence for the use of topicals in SD and to propose a structured approach in managing SD. A systematic search of published literature and manufacturer website information for topicals in SD was carried out. The results showed that there are few studies (n = 11) which investigate the efficacy of topicals in management of SD. Trofolastin and Alphastria creams demonstrated level-2 evidence of positive results for their prophylactic use in SD. Additionally, tretinoin used therapeutically showed varying results whilst cocoa butter and olive oil did not demonstrate any effect. Overall, there is a distinct lack of evidence for each topical formulation. The majority of topicals failed to mention their effect on early vs. later stages of SD (striae rubrae compared to striae albae) and their role in both prevention and treatment. In conclusion, there is no topical formulation, which is shown to be most effective in eradicating or improving SD. A structured approach in identification and targeted management of symptoms and signs with the appropriate topical is required. Randomized controlled trials are necessary to assess the efficacy of topical products for treatment and prevention of different stages of SD.
