Coconut, castor, and argan oils are popular commercial hair oils culturally rooted in current and historical Indian and African heritages. Dermatologists treating hair and scalp conditions often face challenging patient questions of whether over-the-counter hair oils should be used. This is particularly challenging given the deeply rooted cultural practices of some skin of color patients. As a result, many dermatologists recommend patients to continue using hair oils not based on clinical efficacy but rather lack of foreseeable side effects. We analyzed the literature to investigate claims to substantiate whether these hair oils can improve hair growth, hair quality, and treat infestation clinically. Based on 22 articles that met inclusion criteria, coconut oil has been shown to treat both brittle hair and hair infestation clinically, with limited evidence regarding its impact on hair growth. There is weaker evidence for castor oil improving hair quality by increasing hair luster, and no strong evidence supporting its use for hair growth or treatment of infestation. Argan oil does not have any significant evidence supporting its use to improve hair growth, quality, or treatment of infestation. J Drugs Dermatol. 2022;21(7):751-757. doi:10.36849/JDD.6972.

Review
INTRODUCTION
Androgenetic alopecia (AGA) has negative impacts on both men and women in terms of appearance and mental stress. Spironolactone is a synthetic aldosterone receptor antagonist known to stimulate hair growth and has been widely used by dermatologists to treat AGA.
OBJECTIVE
To conduct a systematic review evaluating the efficacy and safety of topical and oral spironolactone in AGA treatment.
METHODS
We searched PubMed, Embase, the Cochrane Library, and the Web of Science until October 23rd, 2022, for human studies evaluating the efficacy of spironolactone for the treatment of AGA, regardless of doses and routes.
RESULTS
We retrieved 784 papers and ultimately 7 articles matched our inclusion criteria and comprised 618 AGA patients (65 men, 553 women), 414 of them received spironolactone treatment. Oral spironolactone doses ranged from 25mg to 200mg daily, with the vast majority between 80mg and 110 mg. Dosage forms for topical spironolactone use include gels of 1% and solutions of 5% twice daily. Both oral and topical spironolactone have been shown efficacy for alopecia recovery, but topical use has significantly fewer side effects and is suitable for any gender. It showed better efficacy in combination with other therapies such as oral or topical minoxidil compared with monotherapy.
CONCLUSION
Spironolactone is an effective and safe treatment of androgenic alopecia which can enhance the efficacy when combined with other conventional treatments such as minoxidil. Topical spironolactone is safer than oral administration and is suitable for both male and female patients, and is expected to become a common drug for those who do not have a good response to minoxidil. Furthermore, more high-quality clinical randomized controlled studies should be performed.

Meta-Analysis Review
The objective was to assess the global oral lichen planus prevalence. We searched PubMed, EMBASE, Web of Science, and Scopus for studies published before September 2019. We evaluated the quality of studies and carried out several meta-analyses. The global pooled prevalence was 1.01%, with a marked geographical difference (p < .001). The highest prevalence was reported from Europe (1.43%) and the lowest in India (0.49%), where tobacco-associated keratosis appears to mask oral lichen planus resulting in attenuation of its prevalence. From the age of 40 years, the prevalence increases significantly and progressively (OR = 3.43, 95% CI = 2.48-4.73, p < .001). Studies that define diagnostic criteria report a higher prevalence (1.31% vs. 0.70%, p = .03), although the application of the WHO criteria (year 1978-2007) does not increase the ability to diagnose the disease compared with other criteria (p = .11). The studies performed by oral medicine/oral pathology specialists report significantly higher prevalence (1.80%) than dentists (0.61%) and dermatologists (0.33%; p < .001). In conclusion, we propose that reliable diagnostic criteria should be defined, which should include a set of essential criteria including the presence of white reticular lesions in any location of the oral mucosa. The impact of histopathological confirmation with defined diagnostic criteria must be researched in the future, although its main use should be to determine the presence or absence of epithelial dysplasia. The necessity to improve the knowledge of oral lichen planus among dentists and dermatologists through continuing education is apparent in the results of this meta-analysis.

Review
Patients with major presentations of alopecia experience physically harmful effects and psychological comorbidities, such as depression and anxiety. Oral minoxidil (OM) has been suggested by dermatologists as a potential remedy; however, its effectiveness remains unclear. This systematic review aims to collate published studies and to analyze the effect of OM among patients diagnosed with any type of alopecia. For this systematic review, Medline/PubMed, Cochrane Central, EMBASE, Web of Sciences, and Latin American and Caribbean Health Sciences Information System were searched for relevant studies from inception to September 21, 2019. Of 1960 studies retrieved in several electronic databases and three additional records identified though reference list from potentially eligible studies, nine studies (one randomized controlled trial and eight nonrandomized controlled trials) met the requirements and were used in our analysis. Although we found positive effects in favor of OM, this should be interpreted cautiously due to very low quality of the evidence of outcomes in the selected studies. Definitive conclusions are not possible without high-quality trials. This review has highlighted the absence of high-quality randomized controlled trials evaluating OM in the treatment of various types of alopecia. Given the mild adverse events of OM, future studies should also analyze doses and duration to maximize efficacy and decrease side effects.

BACKGROUND
Idiopathic intracranial hypertension (IIH) is a condition with increased intracranial pressure of unknown etiology. Its presenting symptoms include persistent headache, pulsatile tinnitus, and visual obscuration. It tends to occur in obese women of childbearing age, and its greatest risk is irreversible loss of vision. Some of the commonly used medications in dermatology, especially those for acne vulgaris, have been associated with IIH. However, the creation of specific risk categories for drugs as a guide for clinicians has never been performed.
OBJECTIVE
The aim of this study was to critically assess all published cases of IIH and identify high-risk drugs associated with drug-induced intracranial hypertension (DIIH), to assist dermatologists and other physicians with patient education and monitoring of symptoms of secondary intracranial hypertension.
METHODS
MEDLINE, EMBASE, and Cochrane Review Databases were searched for all cases of IIH thought to be drug-related between January 1900 and June 2019. A total of 5117 articles were identified, and 235 articles were found to be relevant. All cases were assessed to satisfy the modified Dandy criteria for diagnosis of IIH, and the likelihood of each case being a 'definite' adverse drug reaction (ADR) was determined using the Koh algorithm for ADR. An association category (from weakly associated [Category I] to strongly associated [Category V]) was assigned based on the number of cases meeting these two criteria.
RESULTS
There were 259 verifiable cases of DIIH. Vitamin A derivatives, tetracycline-class antibiotics, recombinant growth hormone, and lithium were found to be most strongly associated with DIIH (Categories IV and V). Corticosteroids were moderately associated with DIIH (Category III). Drugs that were weakly associated with DIIH (Categories I and II) include cyclosporine, progestin-only contraceptives, combined oral contraceptives, second- and third-generation fluoroquinolones, sulfenazone, gonadotropin-releasing hormones and luteinizing hormone-releasing hormone agonist, nalidixic acid, amiodarone, stanozolol, danazol, divalproic acid, sulfasalazine, ketoconazole, and ustekinumab.
CONCLUSION
We suggest using the term 'drug-induced intracranial hypertension' (DIIH) and propose a set of diagnostic criteria for DIIH. Our review attempts to identify DIIH-associated drugs based on a strict diagnostic and drug-causality algorithm, then stratify them into appropriate risks categories. This may ultimately assist physicians in counselling patients about the risk of DIIH when prescribing medications and recognizing this uncommon yet sight-threatening condition.

Meta-Analysis Review
BACKGROUND
Tofacitinib, a potent JAK inhibitor, has gained increasing interest, in recent years, among dermatologists for the management of refractory alopecia areata. Despite a growing number of studies on its safety and efficacy, there is still a lack of clarity, especially in the pediatric population, in treatment considerations such as proper dosage, treatment duration, side-effect profile, and therapeutic strategies to guide clinicians.
METHODS
Multiple databases were systematically searched. Following the PRISMA diagram, of a pool of 601 papers, seven met a checklist of inclusion criteria. These were observational studies including a total of 59 patients from four to 19 years of age.
RESULTS
In the evaluated studies, tofacitinib was administered either orally at a 2.5 to 15 mg daily (mostly 5 mg twice a day) dosage for 2 to 38 months or in the form of a 2% topical solution for 3-17 months. Metanalysis showed that 49% (95% CI: 29%-69%, I = 59.94%) of patients experienced a reversal of alopecia after a minimum of 3 to 9 months of therapy. Fifty-five percent (95% CI: 23%-86%, I = 75.07%) and 41% (95% CI: 23%-59%, I = 0.00%) showed Good/complete and partial response rates, respectively. Oral administration was significantly more efficacious than topical application (73% vs 23%, p-Value = 0.04). Few side effects such as diarrhea and mild liver transaminases abnormalities were noted in several patients.
CONCLUSION
Results of this review suggest that tofacitinib at 2.5-15 mg daily (especially 5 mg twice daily) oral formulation or 2% topical solution can be regarded as a viable alternative or adjunct to the conventional treatment options for moderate to severe forms of alopecia areata in children owing to its acceptable efficacy and side-effect profile. However, uncertainties continue to exist around treatment strategies including initial and maintenance dosages, route of administration, dose adjustments, the timing of tapering or discontinuation, and associated treatment modalities.

Review
Androgenetic alopecia is the most common cause of hair loss [. 2011 Jan;164(1):5-15]. Finasteride and minoxidil are the only approved treatments [. 2008 Oct;59(4):547-8 and . 2018 Jan;32(1):11-22]. Dutasteride is more potent than finasteride due to its ability to inhibit both 5-α-reductase type I and II [. 2017 Sep;9(1):75-9] though its adverse effects and long half-life contribute to the reluctance on its oral use. Mesotherapy could be a feasible alternative to avoid systemic exposure and side effects [. 2009 Feb;20(1):137-45]. We aim to perform a systematic review to analyze scientific literature with the purpose of comparing efficacy and adverse effects of both administration routes. Five clinical trials using oral route and 3 intralesional in comparison with placebo met criteria for inclusion. Regarding intralesional dutasteride, only one study [. 2001 Mar;19(2):149-54] reported the mean change in hair count. Although both interventions favor over placebo, there are not enough data to reliably compare outcomes obtained between both routes. Mean increase in hair count observed with oral dutasteride was higher (MD: 15.92 hairs [95% CI: 9.87-21.96]; = <0.00001; = 90%) compared to intralesional dutasteride in Abdallah's study (MD: 7.90 hairs [95% CI: 7.14-8.66]; = <0.00001). Future studies are required to assess the therapeutic efficacy of both treatment routes, including head-to-head treatments before well-supported conclusions can be established.

The field of dermatology has seen numerous therapeutic innovations in the past decade with platelet-rich plasma (PRP), recently garnering significant interest in alopecia, acne scarring, and skin rejuvenation. In other conditions of dermatology, such as chronic wounds and vitiligo, PRP has been investigated but has received less attention. The objective of this literature review was to focus on conditions of medical dermatology and to consolidate the available evidence on PRP for the practicing dermatologist. This review evaluates the literature up to October 31, 2018, and a search was conducted in the PubMed database for "platelet-rich plasma," "platelet releasate," "platelet gel," "platelet-rich fibrin" or "PRP" and "dermatology," "skin," "cutaneous," "wound," or "ulcer." In total, 14 articles met the inclusion criteria for this review. In studies representing Levels of Evidence 1b-4 according to the Centre for Evidence-Based Medicine, Oxford, PRP significantly improved wound healing in chronic diabetic ulcers, venous ulcers, pressure ulcers, leprosy ulcers, acute traumatic wounds, and ulcers of multifactorial etiologies. Two studies also documented benefits of adjunctive PRP in stable vitiligo. In chronic wounds of multiple etiologies and vitiligo, PRP warrants further investigation because it represents a potential therapeutic adjunct or alternative with a favorable side effect profile.

Review
BACKGROUND
Thread lifting procedures for facial rejuvenation have made great strides with the development of absorbable threads. Although they have gained fame among plastic surgeons and dermatologists, there have been very few studies published in scientific articles on the effects of absorbable threads in facial rejuvenation, as well as few studies published by aesthetic physicians. The most effective and efficient techniques to determine the adequate place to insert the reabsorbable thread, and the different ways to evaluate the effectiveness of these aesthetic procedures, are still unknown.
OBJECTIVES
This review aims to identify, in the scientific literature, the evaluation techniques for a safe and correct insertion of PDO threads in facial rejuvenation procedures.
METHODOLOGY
A review of scientific literature was performed using the following list of keywords, descriptors, or thesauri: PDO threads, aesthetics, facial rejuvenation. Scopus, PubMed, and Web of Science databases were used for the literature search. Articles from years 2012-2022 were selected. The reference lists of the identified articles were included. (16) out of (35) articles associated with the topic were selected. Simple and compound searches were performed with the keywords and very few rigorous studies about the use of PDO threads for aesthetic procedures were found.
RESULTS
Very few rigorous scientific studies on the use of PDO threads for facial rejuvenation procedures were found. There is a strong theoretical and methodological gap on this subject, and, also, on the evaluation techniques that could be used for the safe and correct insertion of the threads.
CONCLUSION
The bibliographic information found shows a huge theoretical and methodological gap in the subject of procedures for facial rejuvenation with PDO threads, as well as the techniques and tools employed to guarantee the correct insertion of the threads.

Review
The prognosis of patients with connective tissue disease (CTD) has improved significantly in recent years, but interstitial lung disease (ILD) associated with connective tissue disease (CTD-ILD) remains a refractory condition, which is a leading cause of mortality. Because it is an important prognostic factor, many observational and interventional studies have been conducted to date. However, CTD is a heterogeneous group of conditions, which makes the clinical course, treatment responses, and prognosis of CTD-ILD extremely diverse. To summarize the current understanding and unsolved questions, the Japanese Respiratory Society and the Japan College of Rheumatology collaborated to publish the world's first guide focusing on CTD-ILD, based on the evidence and expert consensus of pulmonologists and rheumatologists, along with radiologists, pathologists, and dermatologists. The task force members proposed a total of 27 items, including 7 for general topics, 9 for disease-specific topics, 3 for complications, 4 for pharmacologic treatments, and 4 for non-pharmacologic therapies, with teams of 2-4 authors and reviewers for each item to prepare a consensus statement based on a systematic literature review. Subsequently, public opinions were collected from members of both societies, and a critical review was conducted by external reviewers. Finally, the task force finalized the guide upon discussion and consensus generation. This guide is expected to contribute to the standardization of CTD-ILD medical care and is also useful as a tool for promoting future research by clarifying unresolved issues.
