Abstract
The continuous research advances in the microbiome field is changing clinicians’ points of view about the involvement of the microbiome in human health and disease, including autoimmune diseases such as alopecia areata (AA). Both gut and cutaneous dysbiosis have been considered to play roles in alopecia areata. A new approach is currently possible owing also to the use of omic techniques for studying the role of the microbiome in the disease by the deep understanding of microorganisms involved in the dysbiosis as well as of the pathways involved. These findings suggest the possibility to adopt a topical approach using either cosmetics or medical devices, to modulate or control, for example, the growth of overexpressed species using specific bacteriocins or postbiotics or with pH control. This will favour at the same time the growth of beneficial bacteria which, in turn, can impact positively both the structure of the scalp ecosystem on the host’s response to internal and external offenders. This approach, together with a “systemic” one, via oral supplementation, diet, or faecal transplantation, makes a reliable translation of microbiome research in clinical practice and should be taken into consideration every time alopecia areata is considered by a clinician.

Abstract
Alopecia areata is a skin disorder characterized by scarless, localized hair loss that is usually managed by topical treatments that might further worsen the condition. Therefore, the current study aimed to develop nano-cubosomes loaded with finasteride (FI) and oregano oil (Or) to improve drug solubility and permeation through skin and then incorporate it into an aloe ferox gel base. An l-optimal coordinate exchange design was adopted to optimize nano-cubosomes. Phytantriol and Alkyl Acrylate were employed as the lipid material, and surfactant respectively for cubosomes manufacture. The produced formulations were assessed for their particle size, entrapment efficiency (EE%), FI steady-state flux (Jss) and minimum inhibitory concentration (MIC) against Pro-pionibacterium acnes. Optimal FI-Or-NCu had a particle size of 135 nm, EE% equals 70%, Jss of 1.85 μg/cm2.h, and MIC of 0.44 μg/ml. The optimum formulation loaded gel gained the highest drug release percent and ex vivo skin permeation compared to FI aqueous suspension, and pure FI loaded gel. Aloe ferox and oregano oil in the optimized gel formulation had a synergistic activity on the FI permeation across the skin and against the growth of p. acne bacteria which could favor their use in treating alopecia. Thus, this investigation affirms the ability of FI-Or-NCu loaded aloe ferox gel could be an effective strategy that would enhance FI release and permeation through skin and maximize its favorable effects in treating alopecia.

Abstract
INTRODUCTION Treating hair loss of Alopecia areata is a quite challenge. The treatment not only needs to be effective but must meet specific requirements in terms of accurate dose, sustain release, comfortable application with aesthetic appearance. Thus, the study was designed to develop sustained release topical patches releasing allicin using different sources, including the extract from fresh and aged garlic, and commercially pure one. METHODS Patches were formulated by solvent casting method using ethylene-vinyl acetate as backing layer and Carbopol® 971P NF (CP) as mucoadhesive polymer. Physicochemical properties were evaluated including weight, thickness, drug content, surface pH, moisture content, folding endurance, and swelling. In addition to in vitro diffusion study across the cellulose and Strat-M® membranes. RESULTS Patches showed good physicochemical properties. No significant difference (p > 0.05) was obvious in the percentage of allicin diffused across cellulose membrane between patch A (loaded with commercial allicin), patch B1 (loaded with fresh garlic extract), and patch C (loaded with aged garlic extract). However, ethanol enhanced the diffusion of allicin. The percentage of allicin diffused across cellulose membrane over 20 h from patch E (45 mg CP, 2 mL fresh garlic extract-equivalent to 60 mg allicin-and 1 mL of ethanol) was 79.94%. The flux and permeability coefficients were 2.62 mg/cm2 /h and 0.52 cm/h, respectively, with an enhancement ratio of 2.60 times the reference patch M (mashed garlic). CONCLUSION Promising development of topical patches of allicin using garlic extract as natural source with lower cost than the commercial pure allicin and higher aesthetic acceptance than the used mashed garlic.

Abstract
PURPOSE The purpose of this study was to provide detailed information about the eyebrow approach for the reduction of the frontal bone and its esthetic results with the help of clinical data available. Thus, suggesting this technique is minimally invasive and highly esthetic for frontal bone management. METHOD In this series, 96 cases were studied, and results were based on variable clinical criteria and satisfaction of patients. All the surgeries were performed through eyebrow incision for the management of fractures. Intraoperatively, minimal tissue dissection, less invasion with reduced operating time was observed. RESULTS Postoperatively, the eyebrow approach leads to its normal contour and esthetics. No complications related to the procedure were seen with partially recoverable neuropraxia and speedy recovery. This makes it an important technique to consider in carefully selected patients. CONCLUSION In craniofacial trauma, frequently involved site is the frontal bone, and its treatment should be completed more esthetically. Eyebrow approach is a good alternative to other surgical approaches, and it is a minimally invasive technique and thus should be practiced for esthetic management of frontal bone fractures.

Abstract
Although mostly seen in the scalp, alopecia can occur in any hair- bearing site of the body. In spite of various modern treatments, total cost, efficacy, safety and drug dependency have caused a global willing towards natural remedies. The aim of this chapter is to focus on medicinal plants mentioned in Canon of Avicenna, one of the most primary medicinal books, for the treatment of alopecia. Databases like PubMed, Scopus and Google Scholar were searched for plants mentioned in Canon for managing alopecia to find studies on their clinical efficacy or mechanisms, which may have attributed to the treatment of alopecia. 25 plants belonging to 16 families have been mentioned in Canon. Most of them have a history of use in ethno-medicine and some are used in hair growth products nowadays. Investigating literatures has shown that anti- inflammatory and immunomodulatory properties are the proposed mechanisms for the treatment of some types of alopecia. Islamic traditional medicine can give new insights for development of multiple natural treatment, which their use in human have been tested for thousands of years. By confirming their efficacy and safety, traditional herbal remedies are appropriate alternatives for chemicals mainly used for alopecia.

Abstract
Purpose & methods Several single-nucleotide polymorphisms (SNPs) in the promoter region of the TNF-α gene can cause variations in the gene regulatory sites and act as risk factors for some autoimmune disorders as alopecia areata (AA) and vitiligo. This study aimed to detect the serum TNF-α (sTNF) level (by ELISA) and the rs1800629 (by real-time PCR) among AA and vitiligo Egyptian patients and to determine their relation with disease duration and severity. In silico analysis of this SNP to study the molecular regulation of the mutant genotypes was also done. Results In AA patients, no risk was associated with the mutant genotypes vs. the normal genotype, or with A allele vs. G allele. The risk of vitiligo was significantly higher with the G/A and A/A genotypes compared with HCs (p = 0.011). Similarly, a significantly increased risk was noted in patients with A allele vs. G allele (p<0.0001). In AA and vitiligo patients, a significant increase in sTNF-α levels was noted in the mutant G/A genotypes vs. the normal G/G genotype (p<0.0001) and in the A allele vs the G allele (p<0.0001). According to the in silico analysis, this SNP could mainly affect the SP1 transcription factor binding site with subsequent effect on TNF-α expression. Conclusion According to results of the laboratory and the in silico study, the mutant TNF-α (308) genotypes were risk factors that conferred susceptibility to vitiligo among Egyptian patients but had no effect on the susceptibility to AA.

Abstract
Nowadays, the involvement of the microbiome in human health and many human diseases, including that strictly related to the scalphas been brought to the light. Indeed, more recently, authors highlighted the presence of a significant microbial shift both in nonscarring (Androgenetic alopecia and Alopecia areata) and scarring Alopecias. The advent of novel technologies together with the effort of many scientists in the microbiome field could provide in the nearest future a clearest framework about the strict relationship between human healthiness and symbiotic microorganism resident on different ecosystem of our body. In this view, the use of Omics approaches has to be considered as no longer negligible when studying the microbiome implication in human health and disease.

Abstract
BACKGROUND Alopecia Areata (AA) is a common inflammatory immune-mediated non-scarring hair loss; however, the exact genetic susceptibility remains to be clarified. Cytotoxic T-lymphocyte Associated Protein 4 (CTLA4) has emerged as a central and critically important modulator of immune responses and is believed to play a crucial rule in AA pathogenesis. OBJECTIVES To investigate the association of CTLA4 variant (rs231775) within codon 17 with AA risk and outcomes. METHODS Genetic analyses of the rs231775 SNP of CTLA4 gene were performed in 186 males (93 AA patients and 93 controls). RESULTS The rs231775 CTLA4 variant was significantly higher in AA patients in comparison with control subjects especially among heterozygous and dominant model. This association varied significantly with disease severity. CONCLUSIONS Individuals with homozygosity of rs231775 CTLA4 variant represented AA disease risk and increased severity than their counterparts.Abbreviations: AA: Alopecia areata; CTLA4: Cytotoxic T-lymphocyte Associated Protein 4; SNP: Single nucleotide polymorphism; LADA: Latent autoimmune diabetes in adults; SLE: Systemic lupus erythematosus; SCU: Suez Canal University; SALT: Severity of Alopecia Tool; DNA: Deoxyribonucleic acid; RT-PCR: Real-time polymerase chain reaction, HWE: Hardy-Weinberg equation; RA: rheumatoid arthritis.

Abstract
INTRODUCTION Cyclosporine is commonly used in treatment for alopecia areata. It can be administered as a monotherapy or in combination with systemic corticosteroids, with various outcomes. METHODS Efficacy of cyclosporine with and without systemic corticosteroids for alopecia areata was evaluated by a systematic review. Cochrane, EBSCOhost, Pubmed, Scopus and Web of Science databases were searched. Only studies published before January 2020 were included. RESULTS A total of 2104 studies were initially examined, of which 14 were eligible for the systematic review. Among 340 reported cases, 213 had focal, multifocal or ophiasis form of alopecia areata, 60 were diagnosed with alopecia totalis and 67 with alopecia universalis. The mean response rate in the whole group of patients at the end of treatment was 65.00% (221/340; range 25-100%). Hair regrowth rate was higher in the group with cases of alopecia areata limited to scalp (124/165; mean 75.15%; range 40-100%) than in the cases with alopecia totalis (30/46; mean 65.22%; range 25-100%) or alopecia universalis (24/52; mean 46.15%; range 25-100%). The combined therapy with systemic corticosteroids was superior to the monotherapy (152/219; mean 69.41%; 0-80% vs. 69/121; mean 57.02%; range 6.67-100%) and had a lower recurrence rate (39/108; mean 36.11% vs. 34/46; mean 73.91%, respectively). The combined treatment with methylprednisolone was significantly more effective when compared to the cyclosporine monotherapy (124/183; mean 67.76%; range 0-80% vs. 69/121; mean 57.02%; range 6.67-100%). The mean time of treatment was 6.75 months (range 2-36). LIMITATIONS Limitations of our study were the retrospective character of included studies, differences in doses of prescribed drugs, and duration of the treatment and follow-up times. CONCLUSION Cyclosporine in combination with oral systemic corticosteroids is more effective than in monotherapy for severe alopecia areata.

Abstract
Recalcitrant alopecia areata is not uncommon in clinical practice and some patients experienced either treatment failure or recurrence with most of the conventional therapies. Several studies have evaluated the efficacy of cryotherapy in the treatment of alopecia areata with controversial results. This study aimed to optimize the ideal timing of liquid nitrogen cryospraying to achieve the most favorable results. A total of 75 patients with recalcitrant alopecia areata were treated with superficial cryotherapy, two freeze-thaw cycles, each consisted of 3 to 5, 8 to 10, and 13 to 15 seconds in group A, B, and C, respectively. Good to moderate improvement was achieved in 65.2%, 76%, and 76.2% in groups A, B, and C, respectively, with no statistically significant difference. However, the mean percentage of improvement was significantly higher in group B and C compared to group A (P-value < .05 for each). Superficial liquid nitrogen cryotherapy is an effective therapeutic modality for recalcitrant alopecia areata. Moreover, using 8 to 10 seconds dual freeze-thaw cycles is the optimum timing.

Abstract
The role of microbial dysbiosis in scalp disease has been recently hypothesized. However, little information is available with regards to the association between microbial population on the scalp and hair diseases related to hair growth. Here we investigated bacterial communities in healthy and Alopecia areata (AA) subjects. The analysis of bacterial distribution at the genus level highlighted an increase of Propionibacterium in AA subjects alongside a general decrease of Staphylococcus. Analysis of log Relative abundance of main bacterial species inhabiting the scalp showed a significant increase of Propionibacterium acnes in AA subjects compared to control ones. AA scalp condition is also associated with a significant decrease of Staphylococcus epidermidis relative abundance. No significant changes were found for Staphylococcus aureus. Therefore, data from sequencing profiling of the bacterial population strongly support a different microbial composition of the different area surrounded hair follicle from the epidermis to hypodermis, highlighting differences between normal and AA affected the scalp. Our results highlight, for the first time, the presence of a microbial shift on the scalp of patients suffering from AA and gives the basis for a larger and more complete study of microbial population involvement in hair disorders.

Abstract
Background: Alopecia areata (AA) is a non-scarring auto-immune hair disorder. Recent researches explained the role of growth factors (GFs) in hair follicle cycling. The main reservoir of GFs are alpha-granules of platelets and novel procedures have been implemented aimed at collecting platelet-rich plasma (PRP). PRP has been safely implemented in many medical applications and has also been successfully used as alternative cell-based therapy for the treatment of hair growth disorders, among which also AA. Objectives: By means of a randomized double-blinded, placebo and active-controlled, parallel group study we have studied the efficacy of a cosmetic product (named TR-M-PRP plus) comprising biomimetic peptides specific for hair growth, mimicking PRP composition for the treatment of AA. Subjects were treated for three months and evaluated, at the end of the study and after one month of follow-up, as regards hair growth using SALT score. Results: TR-M-PRP plus-like topic produced a statistically significant (p < .001) clinical improvement in SALT score after 3 months of therapy, compared to baseline. Hair growth results further improved after 1 month of follow-up. Conclusions: This clinical investigation suggests that the biotechnological designed PRP-like cosmetic could represent a valid and safer alternative to autologous PRP for the treatment of AA.

Abstract
Erythroid differentiation regulator 1 (Erdr1) is known to be involved in the inflammatory process via regulating the immune system in many cutaneous disorders, such as psoriasis and rosacea. However, the role of Erdr1 in various hair loss disorders remains unclear. The aim of this study was to investigate the putative role of Erdr1 in alopecias. Skin samples from 21 patients with hair loss disorders and five control subjects were retrieved, in order to assess their expression levels of Erdr1. Results revealed that expression of Erdr1 was significantly downregulated in the epidermis and hair follicles of patients with hair loss disorders, when compared to that in the control group. In particular, the expression of Erdr1 was significantly decreased in patients with alopecia areata. We propose that Erdr1 downregulation might be involved in the pathogenesis of hair loss, and could be considered as a novel biomarker for hair loss disorders.
