Review
Approved fibroblast growth factor receptor (FGFR) inhibitors include erdafitinib, pemigatinib, and futibatinib. We review the most common toxicities associated with FGFR inhibitors and provide practical advice regarding their management. Hyperphosphatemia can be managed with careful monitoring, dose reduction or interruption, a prophylactic low-phosphate diet, and phosphate-lowering therapy. Ocular adverse events (AEs) are managed by withholding or adjusting the dose of the FGFR inhibitor. Dermatologic AEs include alopecia, which can be managed with minoxidil, and dry skin, which can be treated with moisturizers. Hand-foot syndrome can be prevented by lifestyle changes and managed with moisturizing creams, urea, or salicylic acid. Among gastrointestinal AEs, diarrhea may be managed with loperamide; stomatitis can be managed with baking soda rinses, mucosa-coating agents, and topical anesthetics; and dry mouth may be alleviated with salivary stimulants. Most FGFR inhibitor-associated toxicities are manageable with prophylactic measures and treatments; proactive monitoring is key to ensuring optimal clinical benefits.

Randomized Controlled Trial
Comparison between topical cetirizine with minoxidil versus topical placebo with minoxidil in female androgenetic alopecia: a randomized, double-blind, placebo-controlled study.
Androgenetic alopecia (AGA) is the most common cause of hair loss in both genders with a higher psychological impact on females. Currently, topical minoxidil is the only FDA-approved treatment for female AGA and it needs life-long application and causes side effects. Cetirizine is an antihistamine that may be effective in hair loss treatment. This study aimed to compare the efficacy and safety of topical cetirizine with minoxidil (group 1) versus topical minoxidil with placebo (group 2) in female patients with AGA. This was a double-blind, randomized, controlled, parallel study conducted at Dermatology Clinic, Cairo University Teaching Hospital (Kasr- Al- Ainy), Egypt. Sixty-six patients with female AGA, aged 20-50 years, Sinclair (II-IV), were randomly assigned to one of the 2 groups for 24 weeks. The trichoscopic parameters, patients' self-assessment, side effects and global photographic assessment were evaluated. There was a statistically significant change from baseline in frontal and vertex terminal and vellus hair density (P < 0.0005) with a significant increase in vertex hair shaft thickness and average number of hairs per follicular unit in group 1 (P < 0.05). Patients reported significantly better scores in patient self-assessment in group 1 (P < 0.05). Side effects were not significantly different between groups (P > 0.05). Topical cetirizine increases hair shaft thickness and results in a higher clinical improvement from patients' perspective with a good safety profile (NCT04481412, study start date: July 2020).

Review
Androgenetic alopecia (AGA) is the most common cause of alopecia in males and females. Minoxidil and finasteride are the only FDA-approved treatments for AGA. New treatments including Platelet Rich Plasma (PRP) and microneedling have shown promising results. The purpose of this literature review was to highlight recent studies examining the effects of topical minoxidil combined with PRP to minoxidil or PRP monotherapy. The method used for this paper includes a systematic review of the literature from 2010 to 2022 using the PubMed, EMBASE, and MEDLINE databases examining studies evaluating combination therapies for AGA. Three randomized control trials compared combination PRP + topical 5% minoxidil to either no treatment, 5% minoxidil, or PRP only. Two studies found increased hair growth at five months and at six months following combined therapy. Another study found an increase in hair density and improved patient satisfaction with combination therapy compared to monotherapy. A prospective study revealed that patients treated with combined 5% minoxidil, PRP, and microneedling reported the highest patient and physician satisfaction compared to minoxidil monotherapy. An observational study evaluating topical 5% minoxidil with PRP reported an increase in hair diameter after one year of combination treatment compared to minoxidil monotherapy. PRP therapy combined with minoxidil and microneedling in a retrospective study was shown to increase hair growth compared to PRP with minoxidil as well as PRP or minoxidil monotherapy. In conclusion, a variety of studies demonstrated superior treatment response with a combination of PRP and minoxidil therapy in patients with AGA. Limitations to this study include different PRP preparation protocols, few randomized control studies, and small sample sizes.

Finasteride and minoxidil are medicaments commonly prescribed for treating benign prostatic hyperplasia (BPA), hypertension, and/or androgenetic alopecia (AGA). The mechanism of action of finasteride is based on the interference in androgenic pathways, which may lead to fertility-related disorders in men. Minoxidil, however, can act in multiple ways, and there is no consensus that its use can adversely affect male fertility. Since finasteride and minoxidil could be risk factors for male fertility, we aimed to compare their impact on the two reproductive organs testis and epididymis of adult murine models, besides testis/epididymis-related cells, and describe the mechanism of action involved. For such, we used the PRISMA guideline. We included 31 original studies from a structured search on PubMed/MEDLINE, Scopus, and Web of Science databases. For in vivo studies, the bias analysis and the quality of the studies were assessed as described by SYRCLE (Systematic Review Centre for Laboratory Animal Experimentation). We concluded that finasteride and minoxidil act as hormone disruptors, causing oxidative stress and morphological changes mainly in the testis. Our results also revealed that finasteride treatment could be more harmful to male reproductive health because it was more associated with reproductive injuries, including damage to the epididymis, erectile dysfunction, decreased libido, and reduced semen volume. Thus, this study contributes to the global understanding of the mechanisms by which medicaments used for alopecia might lead to male reproductive disorders. We hope that our critical analysis expedites clinical research and reduces methodological bias. The registration number on the Prospero platform is CRD42022313347.

Review
Patterned hair loss (PHL) is a severe hair condition that affects both sexes. Mesotherapy is a treatment that involves microinjecting medications and/or vitamins into the middle layer of the skin. Mesotherapy reduces systemic adverse effects by delivering drugs directly to the hair follicle, increasing local bioavailability while lowering systemic exposure. Local side effects and reactions may develop due to mesotherapy. This study systematically evaluated the safety and efficacy of mesotherapy to minoxidil 5%, as well as addressing its limitations, dosing, and technique, with the intent of providing valuable trials and insights for clinicians and patients considering mesotherapy for improved androgenetic alopecia (AGA) outcomes. The literature search carried out by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria yielded 11 relevant studies from an initial pool of 18 articles. These studies covered various aspects of the role of mesotherapy and minoxidil in AGA, including techniques, complications, limitations, and outcomes. In conclusion, available trials and research on mesotherapy and minoxidil demonstrated excellent statistical significance and a high patient satisfaction rate, with the exception of two publications that took into account certain uncommon adverse effects of mesotherapy. However, recent research suggests that a mesotherapy method for alopecia with a low risk of side effects is effective.

Procollagen-lysine, 2-oxoglutarate 5-dioxygenase 2 (PLOD2) has been reported as an oncogenic gene, affecting various malignant tumors, including endometrial carcinoma, osteosarcoma, and gastric cancer. These effects are mostly due to the enhanced deposition of collagen precursors. However, more studies need to be conducted on how its lysyl hydroxylase function affects cancers like colorectal carcinoma (CRC). Our present results showed that PLOD2 expression was elevated in CRC, and its higher expression was associated with poorer survival. Overexpression of PLOD2 also facilitated CRC proliferation, invasion, and metastasis in vitro and in vivo. In addition, PLOD2 interacted with USP15 by stabilizing it in the cytoplasm and then activated the phosphorylation of AKT/mTOR, thereby promoting CRC progression. Meanwhile, minoxidil was demonstrated to downregulate the expression of PLOD2 and suppress USP15, and the phosphorylation of AKT/mTOR. Our study reveals that PLOD2 plays an oncogenic role in colorectal carcinoma, upregulating USP15 and subsequently activating the AKT/mTOR pathway.

Randomized Controlled Trial
INTRODUCTION
Treatments for AGA have yet to produce satisfactory outcomes and may cause intolerable side effects. Recent studies have reported that adipose tissue-derived stem cell conditioned media (ADSC-CM) could induce hair growth and regeneration.
OBJECTIVE
To investigate the efficacy of ADSC-CM combined with minoxidil for hair regeneration therapy in male AGA.
METHODS
This study lasted for 6 weeks. Subjects were divided into two groups: concentrated and non-concentrated ADSC-CM. Scalp was divided vertically in half before intradermal injection was administered from the frontal region of the scalp toward the vertex with a 30G needle, spaced about 1 cm apart. Treatment side received 2 ml of ADSC-CM; the other side was given 2 ml of NaCl 0.9% as placebo. Patients applied 5% minoxidil twice daily post-injection. Improvements were assessed using photographs and trichoscan every 2 weeks.
RESULTS
Hair count, hair density, and mean thickness increased significantly on both sides after 6 weeks, while vellus rate decreased proportionally with the increase of terminal rate. No statistically significant differences between treatment groups were found. Minimum side effects were reported, and subjects were satisfied with the results.
CONCLUSION
Combination of ADSC-CM and minoxidil could be a potential agent for hair regrowth. Follow-up research with extensive populations, longer duration, and different study design may be required to confirm the exact mechanisms of ADSC-CM on hair growth.
