Review
Lichen planopilaris and frontal fibrosing alopecia are primary scarring alopecias where diagnosis can be suggested by clinical and trichoscopy features, especially in the early stages, but scalp biopsy is the standard exam for definitive diagnosis. Frontal fibrosing alopecia is considered a variant of lichen planopilaris, as the histopathological findings are similar, with a perifollicular lymphohistiocytic infiltrate, sometimes with a lichenoid pattern. A thorough clinical examination, trichoscopy and photographic documentation are essential to assess the evolution and therapeutic response. To date, there are no validated treatments or guidelines for these diseases, but there are recommendations that vary with the individual characteristics of each patient. This article presents a comprehensive review of the literature, including an update on topics related to the diagnosis, follow-up, histopathological aspects and available treatments for lichen planopilaris and frontal fibrosing alopecia, highlighting their similarities, differences and peculiarities.

Review
Pattern hair loss is the most common type of hair loss in both men and women. Scalp hair is typically affected in a characteristic distribution without other scalp or dermatologic findings. Early recognition and treatment can help halt its progression to preserve as much hair as possible. Both pharmacologic and nonpharmacologic treatments have proven helpful.

Genome-wide association studies have identified many loci associated with hair and skin disease, but identification of causal variants requires deciphering of gene-regulatory networks in relevant cell types. We generated matched single-cell chromatin profiles and transcriptomes from scalp tissue from healthy controls and patients with alopecia areata, identifying diverse cell types of the hair follicle niche. By interrogating these datasets at multiple levels of cellular resolution, we infer 50-100% more enhancer-gene links than previous approaches and show that aggregate enhancer accessibility for highly regulated genes predicts expression. We use these gene-regulatory maps to prioritize cell types, genes and causal variants implicated in the pathobiology of androgenetic alopecia (AGA), eczema and other complex traits. AGA genome-wide association studies signals are enriched in dermal papilla regulatory regions, supporting the role of these cells as drivers of AGA pathogenesis. Finally, we train machine learning models to nominate single-nucleotide polymorphisms that affect gene expression through disruption of transcription factor binding, predicting candidate functional single-nucleotide polymorphism for AGA and eczema.

Journal of Traditional Chinese Medicine... Oct 2020To evaluate the efficacy of scalp-acupuncture on subjects with hemiplegic paralysis of acute ischaemic stroke (AIS). (Randomized Controlled Trial)
Randomized Controlled Trial
OBJECTIVE
To evaluate the efficacy of scalp-acupuncture on subjects with hemiplegic paralysis of acute ischaemic stroke (AIS).
METHODS
One hundred and twenty patients with hemiplegic paralysis of 1 to 7 d post stroke, aged 40 to 75 years, were randomly allocated to receive either standard care (control group) or standard care plus 30 min of scalp-acupuncture applied to the bilateral anterior oblique line of the vertex-temporal (MS6) for 14 d (6 d/week) (trial group). The outcome measures included the National Institutes of Health Stroke scale (NIHSS) for neurological deficits, the Fugl-Meyer assessment (FMA) for limb impairment, and Barthel index (BI) for activities of daily living before and after intervention. The manual muscle test (MMT) was assessed at pre-intervention, at the first post-intervention immediately, and at the 14th day after intervention commencement. Measurements were recorded by a blinded investigator at different time points after initiating the intervention.
RESULTS
The trial group had a greater increase in MMT (P < 0.05), FMA, and BI scores (P < 0.01), and a greater decrease in NIHSS scores (P < 0.01) from pre-intervention to post-intervention, and the control group had a greater increase in MMT scores (P < 0.05), and a greater decrease in NIHSS scores(P < 0.01) from pre-intervention to post-intervention. The improvement in MMT (P < 0.01), FMA, BI (P < 0.05), and NIHSS (P < 0.01) scores in the trial group was superior to that of the control group. Meanwhile, scalp-acupuncture intervention had an immediate effect on myodynamia of patients with hemiplegic paralysis after acute ischaemic stroke in this randomized controlled trial.
CONCLUSION
The early scalp-acupuncture intervention after stroke effectively increased myodynamia of the affected limbs, improved neurological deficit degrees, and daily living ability.

Review
Despite a significant increase in reported cases of frontal fibrosing alopecia (FFA) in literature, discussion about the possible role of environmental factors, instruction for diagnosis and guideline for treatment, are limited. The review aims to provide a detailed synthesis of this condition that could be used by clinicians in their practise. Whether single-centre or multi-centre, studies of more than 60 cases less than 5 years old were mainly taken into consideration. Results obtained were that FFA affects mainly postmenopausal Caucasian women; the most common comorbidities are hyperlipidaemia, arterial hypertension, osteoporosis, hypothyroidism, depression, alongside dermatological disorders such as atopic dermatitis, rosacea, seborrheic dermatitis and androgenetic alopecia. Autoimmune, genetic, hormonal (e.g. estrogen deficiency, pregnancy, lactation, HRT and raloxifene) and environmental (e.g. daily use of facial sunscreens and less frequent use of hair dyes and shampoo) hypotheses were proposed for pathogenesis, as well as association with various predisposing factors (patient's health-social profile, disease's history and comorbidities). Clinical presentation of FFA can be divided into 3 specific patterns, each with a different prognosis. Diagnosis is usually made clinically with the use of trichoscopy; however, scalp biopsy remains the gold standard. The condition is regarded as a variant of lichen planopilaris (LPP) due to the similarity of the prominent histopathological findings, but the clinical image is distinct and therapeutic options vary. 5α-reductase inhibitors, intralesional steroids, and hydroxychloroquine provide the highest level of evidence for the treatment of FFA. The conclusion is that a better understanding of the disease is crucial for proper disease management.

Randomized Controlled Trial
Plant-derived secondary metabolites (polyphenols/terpenes/alkaloids) and microbial exometabolites/membrane components of fermented tropical fruits are known as highly bioavailable biomolecules causing skin and hair improvement effects (wound healing, anti-inflammatory, antioxidant, antidiabetic, antiacne, skin/hair microbiota balancing, hair growth-promoting, and hair loss-inhibiting). Caffein is considered as a hair growth promoter. A randomized placebo- and caffein-controlled clinical trial on the efficacy of fermented papaya (FP) plus fermented mangosteen (FM) towards human hair quality and loss was conducted. Shampoo and lotion hair care products containing FP, FM, and caffein as active agents were developed and applied to 154 subjects of both sexes with clinically confirmed androgenic or diffuse alopecia for 3 months. Their clinical efficacy was assessed subjectively by questionnaires filled in by dermatologists/trichologists, and by the objective trichomicroscopical calculations. Hair and scalp skin quality was determined by microbiota pattern and ATP, SH-groups, protein, and malonyl dialdehyde quantification. Comparative clinical data showed that the experimental hair care cosmetics significantly inhibited hair loss, increased hair density/thickness, and improved hair follicle structure versus placebo and caffein controls. The cosmetics with FP and FM substantially normalized the microbiota pattern and increased ATP content in hair follicle, while inhibiting lipid peroxidation in the scalp skin, and SH-group formation in the hair shaft.

Randomized Controlled Trial
This study aimed to explore the changes in functional connections between cerebral hemispheres and local brain regions functional activities in patients with acute ischemic stroke (AIS) treated with International Standard Scalp Acupuncture (ISSA). Thirty patients with middle cerebral artery AIS in the dominant hemisphere were selected and randomly divided into two groups such as the control group and the scalp acupuncture group, with 15 patients in each group. Patients in the control group were treated with conventional Western medicine, while patients in the scalp acupuncture group received ISSA (acupuncture at the parietal midline [MS5], acupuncture at the left anterior parietotemporal oblique line [MS6] and acupuncture at the left posterior parietotemporal oblique line [MS7]) for one course of treatment. All patients were evaluated for treatment efficacy and received whole brain resting state functional magnetic resonance imaging (Rs-fMRI) scan before and after treatment. The observational indicators included: (a) the National Institutes of Health Stroke Scale (NIHSS) scores and the simplified Fugl-Meyer Assessment (SFMA) scores; (b) analyses of the amplitude of low-frequency fluctuation (ALFF), regional homogeneity (ReHo) and voxel-mirrored homotopic connectivity (VMHC). The results showed a significant difference in the NIHSS scores before and after treatment in the scalp acupuncture group compared with the control group (p < .05), indicating that patients improved better after scalp acupuncture treatment. Compared with the control group, the VMHC, ALFF and ReHo values in the scalp acupuncture group increased after treatment. The VMHC values increased in the brain regions dominated by bilateral BA6 and BA8; the ALFF values increased in the left BA39 and the adjacent superior temporal gyrus and middle temporal gyrus; and the ReHo values increased in the brain regions extending from left middle temporal gyrus (including BA21) to BA37, and the brain regions extending from the left BA40 and angular gyrus to BA7. The present study indicated that scalp acupuncture can specifically strengthen the functional activities of the brain regions related to sensory integration, language processing and motor coordination in the middle aged and elderly patients with AIS of the dominant cerebral hemisphere, and can strengthen bilateral frontal lobe motor control. This study may provide a scientific basis for the clinical application of ISSA treatment in patients with AIS, and may also provide a preliminary research basis for further animal experiments.
