Calida Danko, Jason Suszko, Nicole Fett
The skin and the eyes are prone to radiation-induced injury in fluoroscopic procedures. The degree of injury is related to various exposure and patient-related factors. We report a man who presented with an alopecic patch on the left occipital scalp following an extended fluoroscopically-guided endovascular procedure. He subsequently experienced complete hair regrowth, but was later diagnosed with a cataract in his left eye. To our knowledge this is the first report of both anagen effluvium and cataract development in a patient following fluoroscopic radiation exposure...

BACKGROUND: Photobiomodulation, also referred to as low-level laser therapy (LLLT), has been studied and used for (among other diseases) the promotion of hair regrowth. OBJECTIVE/MATERIALS AND METHODS/RESULTS: A clinical study was developed to define the physiologic effects that occur when the human hair follicle and surrounding tissue structures are exposed to laser light using a novel device that is fitted with an array of laser diode sources operating at 650 nm and placed inside a sports cap to promote discretion while in use...

Hair follicles (HFs) undergo precisely regulated cycles of active regeneration consisting of (anagen), involution (catagen), and relative quiescence (telogen) phases. HF stem cells (HFSCs) play important roles in regenerative cycling. Elucidating mechanisms that governs HFSC behavior can help uncover the underlying principles of hair development, hair growth disorders and skin cancers. RNA-binding proteins of the Musashi (Msi) have been implicated in the biology of different stem cell types, yet they have not been studied in HFSCs...

BACKGROUND: Given the limited number of therapeutic options, severe childhood alopecia areata (AA) poses a clinical challenge. The best and most rapid response rates can be achieved with high-dose systemic corticosteroids, however, relapse following treatment discontinuation is inevitable. Due to systemic side effects, long-term high-dose corticosteroid regimens are not feasible. Following initial pulse therapy, continuation of corticosteroid therapy at a dose below the Cushing threshold might be able to suppress disease activity without causing severe side effects...

Reports have highlighted serum vitamin D deficiency and reduced 1,25-dihydroxyvitamin D(3) receptors(VDR) expression on hair follicles of alopecia areata(AA) patients. Very few studies have demonstrated efficacy of topical calcipotriol (vitamin D analogue) in AA. We intended to study the efficacy of calcipotriol lotion 0.005% in AA and correlate its outcome with serum vitamin D levels. We conducted a prospective study, in which 22 patients with AA were treated with calcipotriol lotion 0.005% twice daily for 3 months...

BACKGROUND: Bioluminescence imaging (BLI) is a powerful technique for monitoring the temporal and spatial dynamics of gene expression in the mouse brain. However, the black fur, skin pigmentation and hair regrowth after depilation of mouse interfere with BLI during developmental and daily examination. The aim of this study was to extend the application of Arc-Luc transgenic (Tg) mice to the BLI of neuronal activity in the mouse brain by introducing the hairless (HL) gene and to examine Arc-Luc expression at various developmental stages without interference from black fur, skin pigmentation, and hair regrowth...

Alopecia areata (AA) is a chronic, autoimmune disease. The main symptom is massive hair loss, localized or diffuse, in the scalp and the whole body. However, nails may also be involved, and brittleness, fragility and pitting can be signs of nail dystrophy in AA patients. Here, we report the case of a male patient with AA refractory to various treatments, including oral, topical and intralesional corticosteroids, immunosuppressants, cyclosporin and PUVA (oxoralen plus ultraviolet light), all interrupted due to side effects...

Vitamin D receptor (VDR) mutations in humans and mice cause alopecia. VDR-null (VDR(-/-)) mice exhibit lack of postmorphogenic hair cycles as a result of impaired keratinocyte stem cell (KSC) function. To identify the molecular basis for abnormal KSC function, RNA sequencing of wild-type (WT) and VDR(-/-) KSCs was performed. These studies demonstrated that >80% of differentially expressed genes are up-regulated in VDR(-/-) KSCs; thus, the VDR is a transcriptional suppressor in WT KSCs. Peroxisome proliferator-activated receptor γ (PPARγ), PPARγ coactivator 1β (PGC1β), and lipoprotein lipase (LPL) were among the up-regulated genes identified...

Ki Soo Park, Dae Hwan Park
BACKGROUND: Algae have traditionally been used for promotion of hair growth. Use of hair regrowth drugs, such as minoxidil, is limited due to side effects. The aim of this study was to examine a mixture of Saccharina japonica and Undaria pinnatifida (L-U mixture) on hair growth and to compare the promoting effect of hair growth by a 3% minoxidil and a L-U mixture. METHODS: To evaluate the hair growth-promoting activity, saline, 50% ethanol, 3% minoxidil, and the L-U mixture were applied 2 times a day for a total of 14 days on the dorsal skin of C57BL/6 mice after depilation...

Alopecia areata is a common cause of nonscarring alopecia that occurs in a patchy, confluent, or diffuse pattern. Dermoscopy is a noninvasive technique for the clinical diagnosis of many skin diseases. Topical minoxidil solution 5% and platelet rich plasma are important modalities used in treatment of alopecia areata. We aimed to evaluate the efficacy of PRP versus topical minoxidil 5% in the treatment of AA by clinical evaluation and trichoscopic examination. Ninety patients were allocated into three groups; the first was treated with topical minoxidil 5% solution, the second with platelets rich plasma injections, and the third with placebo...

Alopecia areata (AA) involves the immune-related destruction of hair follicles, resulting in patches of complete hair loss, most often on the scalp. The topical sensitizer squaric acid dibutylester (SADBE) is a popular treatment option given its low side-effect profile, hair regrowth potential, and lack of cross-reactivity with other chemicals. We describe a unique case of a 6-year-old girl who developed angioedema after SADBE treatment for AA.

BACKGROUND. Alopecia areata (AA) is a common autoimmune disease with a lifetime risk of 1.7%; there are no FDA-approved treatments for AA. We previously identified a dominant IFN-γ transcriptional signature in cytotoxic T lymphocytes (CTLs) in human and mouse AA skin and showed that treatment with JAK inhibitors induced durable hair regrowth in mice by targeting this pathway. Here, we investigated the use of the oral JAK1/2 inhibitor ruxolitinib in the treatment of patients with moderate-to-severe AA. METHODS...

BACKGROUND: Alopecia areata (AA) is an autoimmune disease characterized by hair loss mediated by CD8(+) T cells. There are no reliably effective therapies for AA. Based on recent developments in the understanding of the pathomechanism of AA, JAK inhibitors appear to be a therapeutic option; however, their efficacy for the treatment of AA has not been systematically examined. METHODS: This was a 2-center, open-label, single-arm trial using the pan-JAK inhibitor, tofacitinib citrate, for AA with >50% scalp hair loss, alopecia totalis (AT), and alopecia universalis (AU)...
