Hair loss in elderly women has been becoming a major topic in the daily practice of dermatology. Aging of hair follicles seems to affect hair growth and pigmentation, the molecular mechanisms of which remain to be elucidated. Further senile changes in physiology and immunity may influence the onset and course of hair diseases. Some preexisting diseases such as androgenetic alopecia usually worsen after menopause, while others, like discoid lupus erythematosus, may attenuate. Hormone surveying, especially with regard to internal androgen-producing tumors, is indicated in postmenopausal women with androgenetic alopecia of sudden exacerbation or with unusual manifestation or other virilizing signs. The prevalence of alopecia totalis and alopecia universalis appears to be much lower in postmenopausal ages as compared to earlier onset. Acute or chronic telogen effluvium is not uncommonly superimposed on androgenetic alopecia. Trichotillomania shows a marked female predominance in the senile age group with a higher rate of psychopathology. Worldwide, tinea capitis has been increasingly observed in postmenopausal women. Frontal fibrosing alopecia, giant cell arteritis and erosive pustular dermatosis involve mainly elder women leading to scarring alopecia. Alopecia induced by tumor metastasis to the scalp must be considered in women with underlying neoplasms, especially breast cancer. Overall, hair loss in postmenopausal women is often multifactorial and warrants a close inspection.

Treatment of Malassezia species associated seborrheic blepharitis with fluconazole.

PubMed

Zisova, Lilia G

2009-01-01

The AIM of the present study was to evaluate the therapeutic effect of fluconazole (FungoIon) in patients with seborrheic blepharitis. Four seborrheic blepharitis patients with Malassezia spp. positive cultures on Dixon's agar were treated with fluconazole (Fungolon) (0.200) weekly for 4 weeks. The therapeutic effect of the treatment was positive in all patients--the clinical symptoms withdrew and cultures became mycologically negative. The results indicate that antifungal agents are efficient in the treatment of seborrheic dermatitis.

Trichotillomania is a psychodermatologic disorder characterized by uncontrollable urge to pull one's own hair. Differential diagnoses include the most common forms of alopecia such as alopecia areata. It is usually associated with depression and obsessive-compulsive disorder. Trichotillomania treatment standardization is a gap in the medical literature. Recent studies demonstrated the efficacy of N-acetylcysteine (a glutamate modulator) for the treatment of the disease. We report the clinical case of a 12-year-old female patient who received the initial diagnosis of alopecia areata, but presented with clinical and dermoscopic features of trichotillomania. She was treated with the combination of psychotropic drugs and N-acetylcysteine with good clinical response. Due to the chronic and recurring nature of trichotillomania, more studies need to be conducted for the establishment of a formal treatment algorithm.

BACKGROUND Alopecia areata is a chronic disorder of the hair follicles and nails, of unknown etiology, with clear autoimmune components and genetic factors. Several therapeutic options have been suggested; however, no treatment is able to modify the disease course. Methotrexate is an immunosuppressant used in various dermatoses and recently introduced as a therapeutic option for alopecia areata. OBJECTIVES To evaluate the efficacy and safety of methotrexate in alopecia areata. METHODS In a retrospective, non-controlled study, we evaluated 31 patients with alopecia areata in current or prior treatment with methotrexate to assess the therapeutic response according to sex, age, pattern of alopecia areata, disease duration, cumulative dose of methotrexate, use of systemic corticosteroids or other treatments, and drug safety. RESULTS Regrowth greater than 50% was observed in 67.7% of patients, with the best responses observed in those with <5 years of disease progression (79%), age over 40 years (73.3%), male patients (72.8%), cumulative dose of methotrexate 1000-1500 mg, and multifocal alopecia areata (93%). Among patients receiving systemic corticosteroids in combination with methotrexate, 77.3% had greater than 50% regrowth, compared with 44.4% in those who used methotrexate alone. The therapeutic dose ranged from 10-25 mg/week. No patient had serious adverse effects. Relapse was observed in 33.3% of patients with more than 50% regrowth. CONCLUSION Methotrexate appears to be a promising and safe medication for the treatment of severe alopecia areata when used alone or in combination with corticosteroids. PMID:25184911

Yellow dots are follicular ostium filled with keratin and/or sebum. Initially, they were exclusively associated with alopecia areata. Currently they have also been described in androgenetic alopecia, chronic cutaneous (discoid) lupus erythematosus, and dissecting cellulitis. Due to the growing importance of trichoscopy and its findings in the evaluation of the scalp, this article describes the main diseases in which yellow dots are a common trichoscopic finding, highlighting its characteristics in each dermatosis.

2013-02-01

Intralesional corticosteroid injections are a common treatment for patchy alopecia areata, the most prevalent subtype of this autoimmune hair disorder. To date, no studies have examined the potential adverse effects of this therapy on bone mineral density (BMD). In this retrospective, cross-sectional case series, 18 patients with patchy alopecia areata treated at 4- to 8-week intervals with intralesional triamcinolone acetonide for at least 20 months were evaluated for BMD using dual-energy x-ray absorptiometry (DXA). Follow-up DXA measurements were obtained in those with abnormal findings. Nine out of 18 patients (50%) had abnormal DXA results. Patients with the following risk factors were more likely to have abnormal BMD: age older than 50 years, body mass index less than 18.5 kg/m2, lack of weight-bearing exercise, smoking history, postmenopausal status, past stress fracture, family history of osteopenia or osteoporosis, and a cumulative intralesional triamcinolone acetonide dose of greater than 500 mg. Patients with patchy alopecia areata who receive chronic intralesional triamcinolone acetonide therapy should be counseled on preventive measures for osteoporosis and monitored for effects on BMD.

[Eyelid hygiene for contact lens wearers with blepharitis. Comparative investigation of treatment with baby shampoo versus phospholipid solution].

Blepharitis due to Meibom gland dysfunction (MGD) is presumed to be one of the main reasons for dry eye symptoms which occur in up to 50% of contact lens users. Thus, MGD presumably plays an important role in dry eye in contact lens wearers. In the present prospective, randomized and double blind trial the efficacy of two established treatment options for MGD and blepharitis was evaluated in symptomatic contact lens wearers. In this prospective, randomized 2-centre trial 53 symptomatic contact lens wearers suffering from blepharitis were included. Patients were randomly selected for two treatment groups: group A performed lid margin hygiene using the commonly recommended mild baby shampoo (Bübchen Kinder Shampoo-extra augenmild, Bübchen Werk Ewald Hermes Pharmazeutische Fabrik GmbH, Soest, Germany) and group B performed lid margin hygiene using a phospholipid-liposome solution specially designed for lid hygiene (Blepha Cura, Optima, Moosburg/Wang, Germany), each for 4 weeks. Before as well as 4 weeks after initiation of this study the following tests were performed: standardized subjective assessment using the ocular surface disease index, non-invasive break-up time (NIBUT) and objective evaluation of lid-parallel conjunctival folds (LIPCOF) and further lid margin criteria by double blinded evaluation of slit lamp photographs. Of the 53 symptomatic contact lens wearers suffering from blepharitis 21 (39,6%) were randomly selected for treatment group A and 32 (60.4%) for group B. In both treatment groups there was objective and subjective improvement of symptoms of dry eye in contact lens wearers. Interestingly, there was a significantly greater improvement, subjective as well as objective, in treatment group B which used the phospholipidliposome solution for lid margin hygiene compared to group A using baby shampoo. Although both therapies improved symptoms of dry eye due to blepharitis in symptomatic contact lens wearers, patients using phospholipid-liposomal solution for lid margin hygiene demonstrated a significantly greater clinical benefit from the therapy. Thus, clinical practice recommending just baby shampoo for lid margin hygiene should be re-considered, as phospholipid-liposomal solution for lid margin hygiene appears to yield greater and faster clinical benefits for symptomatic contact lens wearers suffering from dry eye symptoms.

Necrotizing scleritis as a complication of cosmetic eye whitening procedure

PubMed Central

2013-01-01

Background We report necrotizing scleritis as a serious complication of a cosmetic eye whitening procedure that involves the use of intraoperative and postoperative topical mitomycin C. Findings This is a single case report. A 59-year-old Caucasian male with a history of blepharitis status post uncomplicated LASIK refractive surgery reported chronic conjunctival hyperemia for 15 years prior to undergoing a cosmetic eye whitening procedure. He presented to our clinic 12 months after the cosmetic eye whitening procedure with progressive bilateral necrotizing scleritis and scleral calcification. Conclusions Chronic conjunctival hyperemia may prompt patients to seek surgical correction with cosmetic eye whitening procedures. However, conjunctival hyperemia secondary to tear deficiency and evaporative dry eye may predispose to poor wound healing. Serious complications including necrotizing scleritis may result from cosmetic eye whitening procedures and the use of topical mitomycin C. PMID:23514228

Introduction Favus of the scalp or tinea capitis favosa is a chronic dermatophyte infection of the scalp. In almost cases, favus is caused by Trichophyton schoenleinii, anthropophilic dermatophyte. It is characterized by the presence of scutula and severe alopecia. Besides the classic clinical type of tinea capitis favosa, there are many variant of clinical form which may persist undiagnosed for many years. In this work, we report an atypical form of favus to Trichophyton schoenleinii which was misdiagnosed as tinea amiantacea. Case-report An 11-year old girl came to the outpatient department of dermatology (day 0) with history of tinea amiantacea treated unsuccessfully with keratolytic shampoo (day – 730). She presented a diffuse scaling of the scalp with thick scaly patches and without scutula or alopecia. A diagnosis of tinea favosa by T. schoenleinii was made by mycological examination. She was treated with griseofulvin and ketoconazole in the form of foaming gel for twelve weeks. Despite treatment, clinical evolution was marked by appearance of permanent alopecia patches. The follow-up mycological examination was negative. Conclusion Because of ultimate evolution of favus into alopecia, we emphasize the importance of mycological examination in case of diffuse scaling.

BACKGROUND Scarring alopecias are classified into primary and secondary types according to the initial site of inflammation. In primary scarring alopecias, the hair follicle is the main target of destruction; the term secondary cicatricial alopecia implies that follicular destruction is not the primary pathologic event. AIMS To review the histopathologic diagnoses of cases of cicatricial alopecia in order to classify them according to the North American Hair Research Society. PATIENTS AND METHODS Patients with biopsy specimens diagnosed as cicatricial alopecia seen from 2000 to 2005 at the Dermatologic Department of Hospital das Clinicas, São Paulo University Medical School had hematoxylin and eosin, Periodic acid-Schiff and Weigert stained slides reevaluated and sub-typed into different primary cicatricial alopecias. RESULTS Thirty-eight cases of primary cicatricial alopecias were reclassified as: chronic cutaneous lupus (17), lichen planus pilaris (4), pseudopelade of Brocq (12), folliculitis decalvans (3), dissecting folliculitis (1), and non-specific scarring alopecia (1). In our cases, the methods employed allowed an accurate diagnosis in 12 of 13 cases (92.3%) previously classified as non-specific cicatricial alopecias. CONCLUSIONS Even in the late, pauci or non-inflammatory phases, an approach with systematic evaluation of a constellation of criteria in routine hematoxylin and eosin stain, Periodic acid-Schiff and Weigert stain allowed for a more accurate diagnosis of cicatricial alopecias.

To evaluate the effects of oral azithromycin in patients with posterior blepharitis. Twenty-six eyes of 13 patients with posterior blepharitis diagnosed by a qualified ophthalmologist were enrolled in this study. Patients were instructed to use oral azithromycin 500 mg per day for 3 days in 3 cycles with 7-day intervals. Subjective clinical outcomes were graded and scored 1 day before and 30 days after the end of the treatment (53 days after initiating the treatment) based on severity scores of: (1) eyelid debris; (2) eyelid telangiectasia; (3) swelling of the eyelid margin; (4) redness of the eyelid margin; and (5) ocular mucus secretion. For the assessment of global efficacy, patients were asked by the investigator to rate the subjective symptoms (eyelid itching, ocular itching, eyelid hyperemia, ocular hyperemia, ocular mucus secretion, photophobia, foreign body sensation, and dry eye sensation) on a scale of 0 (no symptoms) to 5 (severe symptoms). Break-up time, Schirmer I test, corneal fluorescein staining score, and rose bengal staining score were also performed in all patients. All clinical outcomes scoring showed statistically significant improvement after oral azithromycin, except for eyelid swelling. Average subjective symptom grading improved statistically after treatment with oral azithromycin, except for eyelid hyperemia, photophobia, and foreign body sensation. Average tear film break-up time values showed statistically significant improvement after the treatment with oral azithromycin. No statistically significant improvement was observed on average values of Schirmer I test, corneal fluorescein staining score, and rose bengal staining score. The combination of multiple clinical parameters shown in this study supports the clinical efficacy of pulsed oral azithromycin therapy for the management of posterior blepharitis.

Female pattern hair loss.

2013-10-01

Female pattern hair loss (FPHL) also known as female androgenetic alopecia is a common condition afflicting millions of women that can be cosmetically disrupting. Prompt diagnosis and treatment are essential for obtaining optimal outcome. This review addresses the clinical presentation of female pattern hair loss, its differential diagnosis and treatment modalities. A) Diffuse thinning of the crown region with preservation of the frontal hairline (Ludwig's type) B) The "Christmas tree pattern" where the thinning is wider in the frontal scalp giving the alopecic area a triangular shaped figure resembling a christmas tree. C) Thinning associated with bitemporal recession (Hamilton type). Generally, FPHL is not associated with elevated androgens. Less commonly females with FPHL may have other skin or general signs of hyperandrogenism such as hirsutism, acne, irregular menses, infertility, galactorrhea and insulin resistance. The most common endocrinological abnormality associated with FPHL is polycystic ovarian syndrome (PCOS). The most important diseases to consider in the differential diagnosis of FPHL include Chronic Telogen Effluvium (CTE), Permanent Alopecia after Chemotherapy (PAC), Alopecia Areata Incognito (AAI) and Frontal Fibrosing Alopecia (FFA). This review describes criteria for distinguishing these conditions from FPHL. The only approved treatment for FPHL, which is 2% topical Minoxidil, should be applied at the dosage of 1ml twice day for a minimum period of 12 months. This review will discuss off-label alternative modalities of treatment including 5-alfa reductase inhibitors, antiandrogens, estrogens, prostaglandin analogs, lasers, light treatments and hair transplantation.

In this cross-sectional study, we aimed to determine the prevalence and characteristics of chronic ocular itch in an outpatient ophthalmology and optometry clinic. Four hundred patients from an outpatient ophthalmology and optometry clinic were enrolled. The presence and characteristics of chronic ocular itch were assessed by a questionnaire. Data regarding ophthalmologic, dermatologic, and systemic conditions as well as current medications were extracted from medical records. Chronic ocular itch was present in 118 (29.5%) of 400 participants. Chronic ocular pruritus was significantly more prevalent in females [ P =0.015; odds ratio (OR)=1.8; 95% confidence interval (CI), 1.1-2.8] and was significantly associated with the presence of allergic conjunctivitis [51.8% (n=45); P <0.001; OR=5.0; 95% CI, 3.0-8.3], dry eye syndrome [40.1% (75); P <0.001; OR=2.6; 95% CI, 1.7-4.1], blepharitis [43.8% (n=21); P =0.021; OR=2.0; 95% CI, 1.1-3.8], and atopic dermatitis [50.0% (n=10); P =0.023; OR=2.6; 95% CI, 1.1-5.8]. Chronic ocular itch was not significantly associated with systemic conditions, or the use of prescribed ophthalmologic medications. Chronic ocular itch is common and may be related to ophthalmologic or dermatologic pathologies. The present findings highlight the importance of identifying and managing this uncomfortable symptom that may negatively impact the quality of life and sleep of affected patients.

To determine whether the Löffler's alkaline methylene blue staining method is better than no staining in detecting Demodex mites in the eyelashes of patients with blepharitis. Eyelashes were collected from 22 patients with blepharitis. The mean age of the patients was 82.5±6.2 years (± SD) with a range from 71 to 93 years. Eyelashes were epilated by forceps and placed individually on microscope slides. The number of Demodex mites was determined by conventional optical microscopy before and immediately after the addition of the methylene blue staining solution. The mean Demodex count before the addition of the methylene blue solution was 2.9±2.9, and it was 4.4±3.9 after the addition of the methylene blue solution ( P <0.01, Wilcoxon test). The methylene blue staining method is a simple and useful method in detecting the presence and quantifying the number of Demodex mites. We recommend the methylene blue staining method not only for the diagnosis of the presence of Demodex mites but also to evaluate the therapeutic effects of medications to eliminate the mite infestation.

Sulfur mustard (SM) has been used as a dangerous chemical warfare agent since the early 20th century. Although many descriptive studies about SM-induced ocular injuries are present in the medical literature, few of them have been conducted over a large group with serious ocular involvement. This descriptive study was conducted on 149 severe SM-intoxicated war veterans. Ocular history, anterior and posterior segment findings using a slit lamp, and direct and indirect ophthalmoscopic findings were recorded. Severity of the disease was also recorded based on a chart of the Foundation of Martyrs and Veterans Affairs. Ocular complains included photophobia (73.2%), sense of decreased vision (72.5%), dry eye sensation (66.4%), foreign body sensation (61.1%), tearing (46.3%), and pain (43.0%). Slit lamp findings were meibomian gland dysfunction (MGD; 96%), blepharitis, punctal closure, trichiasis, tear break-up time, and tear meniscus layer abnormality (80% to 90%). Conjunctival disturbances included vascular abnormality, ischemia, hyperemia, subconjunctival fibrosis, and pterygium. Limbal changes were abnormal vessels, limbal tissue loss and pigment loss, and pannus formation. Corneal problems included epithelial and stromal disturbances, calcium deposition, and melting. The most frequent previous surgeries were punctal closure, lamellar keratoplasty (LK), and stem cell allograft. Severity of intoxication included mild (17%), moderate (25%), and severe (57%). Chronic blepharitis and decreased tear secretion are the 2 most important and influencing factors in progression of ocular problems in SM injuries. The more severe the initial exposure, percentage of disability, and duration of ocular involvement, the higher the likelihood of mustard gas keratopathy.

To determine how frequently Malassezia spp were identified on the periocular skin of dogs and assess the respective associations between the presence of Malassezia spp on the periocular skin and blepharitis, ocular discharge, and the application of ophthalmic medications. Prospective clinical study. 167 eyelids of 84 dogs. Samples obtained from the surface of the eyelid skin by use of adhesive tape were evaluated cytologically for the presence of Malassezia spp. Dogs were grouped on the basis of the presence of blepharitis, nature of ocular discharge, and whether ophthalmic medications were applied, and the proportion of samples with Malassezia spp was compared among the groups. Malassezia spp were detected in 19 samples, of which 15 were obtained from eyes without blepharitis and 14 were obtained from eyes treated with topical ophthalmic medications. The proportion of samples with Malassezia spp was significantly higher for eyes with ocular discharge than for eyes without ocular discharge, especially if that discharge was mucoid or mucopurulent, and for eyes that were treated with aqueous-based medications only or a combination of oil- and aqueous-based medications than for eyes that were not treated. Malassezia organisms were detected on the periocular skin of 3 of 56 (5%) clinically normal dogs. Malassezia organisms were also frequently found on the periocular skin of dogs that had mucoid or mucopurulent ocular discharge or that were administered topical aqueous-based ophthalmic medications, and the periocular skin of these dogs should be cytologically evaluated for Malassezia organisms.

To describe the pathologic changes in punctal stenosis by reporting the histopathologic findings in a series of punctoplasty specimens. Observational retrospective chart review. Electronic health records of all patients having punctoplasty over a 2-year period at an academic oculoplastic practice were examined. All patients whose records included pathology reports were entered into a database. Twenty-four patients, representing 30 eyes, had pathology records in the electronic health records. Patients were 75% women and had an average age of 65 (19-88) years. Associated conditions included blepharitis (71%), dry eye syndrome, or Meibomian gland dysfunction (63%). Histopathologic examination demonstrated chronic inflammation in 11 eyes (36.7%), fibrosis in 7 eyes (23.3%), chronic inflammation and fibrosis in 4 eyes (13.3%), squamous metaplasia in 3 eyes (10%), normal conjunctival mucosa in 3 eyes (10%), and Actinomyces israelii canaliculitis in 2 eyes (6.7%). Nearly all histopathologic specimens revealed findings consistent with inflammation, fibrosis, or both. These findings provide evidence to support the hypothesis that the many etiologic causes of punctal stenosis are linked by a common pathophysiologic mechanism involving inflammation.

Effective treatments, especially for severe multifocal alopecia areata, alopecia areata totalis, and alopecia areata universalis, are lacking. The present article will discuss side effects and relapse rates of different systemic agents for treatment of severe and rapid progressive alopecia areata. © 2011 Wiley Periodicals, Inc.

A novel gammaherpesvirus was identified in a large flying fox (Pteropus vampyrus) with conjunctivitis, blepharitis, and meibomianitis by nested polymerase chain reaction and sequencing. Polymerase chain reaction amplification and sequencing of 472 base pairs of the DNA-dependent DNA polymerase gene were used to identify a novel herpesvirus. Bayesian and maximum likelihood phylogenetic analyses indicated that the virus is a member of the genus Percavirus in the subfamily Gammaherpesvirinae. Additional research is needed regarding the association of this virus with conjunctivitis and other ocular pathology. This virus may be useful as a biomarker of stress and may be a useful model of virus recrudescence in Pteropus spp.

Alopecia areata is one of the most frequent organ-restricted autoimmune diseases, yet its pathogenesis is still unclear. In addition, although alopecia areata often results in significant psychological distress, effective treatment is lacking. New potential susceptibility loci have been implicated, but the strongest evidence points to certain class II human leukocyte antigen alleles. There is new evidence for the collapse of hair follicle immune privilege as a key step in the pathogenesis of alopecia areata. There is also new basic science evidence for stress as a contributing factor in the development of alopecia areata. Few treatments for alopecia areata have been well evaluated in randomized trials. Although multiple potential susceptibility loci have been implicated, the genetics of alopecia areata is still unclear. The role of any potential environmental contributors is also unclear. Quality evidence for efficacy of currently used treatments for alopecia areata is lacking.

Alopecia is a common concern encountered in the medical practice. Treatment approach varies according to the type and severity of alopecia. However, available treatment options have limited efficacy and several adverse effects. Presently, there are different treatment options being studied to overcome these limitations. Additionally, cellular pathways involved in the pathophysiology of alopecia are further being clarified to potentially target pathogenic molecules. We searched the literature for recently published articles discussing new treatment options as well as mechanisms involved in alopecia. We discuss the use of stem cells, growth factors, cellular pathways and robotic hair transplant, among other emerging therapies used for alopecia. Future looks very promising and new effective treatments such as janus kinase inhibitors could possibly be available for alopecia areata. The stem-cell technology is advancing and companies involved in hair follicle neogenesis are starting clinical trials on patients with androgenetic alopecia.

Non-scaring patchy alopecia associated with systematic lupus erythematosus (SLE) is sometimes mis-diagnosed as alopecia areata (AA). Our aim was to differentiate non-scarring patchy SLE alopecia features from patchy AA. Clinical, dermatoscopic and histopathological data from 21 SLE patients with patchy alopecia were compared with data from 21 patients with patchy AA. Incomplete alopecia was common in SLE alopecia patches, while AA patches exhibited complete alopecia. Exclamation-mark hairs, black dots, broken hair and yellow dots were common to AA, while hair shaft thinning and hypopigmentation, angiotelectasis, peripilar sign, perifollicular red dots, white dots and honeycomb pigment patterns were more common in SLE. Interfollicular polymorphous vessels were the most common angiotelectasis presentation in the SLE alopecia patches, but interfollicular arborizing vessels were significantly more common in non-hair-loss-affected SLE regions and in AA hair-loss regions. During follow-up, increased vellus hair was the earliest feature that emerged after treatment both in SLE and AA, while the earliest feature that disappeared was hair shaft hypopigmentation in SLE and broken hair in AA. After treatment, no SLE patients had relapse of alopecia, while 41.7% of AA patients did. Distinct clinical, dermatoscopic and histopathological features were found in SLE-associated alopecia regions, which were different from those of AA. Serological autoantibody tests are of value to confirm the differential diagnosis. Local angiotelectasis and vasculitis close to hair follicles may be involved in the pathogenesis of alopecia in SLE.

Role for the epidermal growth factor receptor in chemotherapy-induced alopecia.

Treatment of cancer patients with chemotherapeutics like cyclophosphamide often causes alopecia as a result of premature and aberrant catagen. Because the epidermal growth factor receptor (EGFR) signals anagen hair follicles to enter catagen, we hypothesized that EGFR signaling may be involved in cyclophosphamide-induced alopecia. To test this hypothesis, skin-targeted Egfr mutant mice were generated by crossing floxed Egfr and Keratin 14 promoter-driven Cre recombinase mice. Cyclophosphamide treatment of control mice resulted in alopecia while Egfr mutant skin was resistant to cyclophosphamide-induced alopecia. Egfr mutant skin entered catagen normally, as indicated by dermal papilla condensation and decreased follicular proliferation, but did not progress to telogen as did Egfr wild type follicles. Egfr mutant follicles responded with less proliferation, apoptosis, and fewer p53-positive cells after cyclophosphamide. Treatment of control mice with the EGFR inhibitors erlotinib or gefitinib similarly suppressed alopecia and catagen progression by cyclophosphamide. Secondary analysis of clinical trials utilizing EGFR-targeted therapies and alopecia-inducing chemotherapy also revealed evidence for involvement of EGFR in chemotherapy-induced alopecia. Taken together, our results demonstrated the involvement of EGFR signaling in chemotherapy-induced alopecia, which will help in the design of novel therapeutic regimens to minimize chemotherapy-induced alopecia.

Frontal fibrosing alopecia and lichen planus pigmentosus: diagnosis and therapeutic challenge*

PubMed Central

Mulinari-Brenner, Fabiane Andrade; Guilherme, Marina Riedi; Peretti, Murilo Calvo; Werner, Betina

2017-01-01

Frontal fibrosing alopecia is a variant of lichen planopilaris with marginal progressive hair loss on the scalp, eyebrows and axillae. We report a case of frontal fibrosing alopecia and lichen planus pigmentosus in a postmenopausal woman, that started with alopecia on the eyebrows and then on the frontoparietal region, with periocular and cervical hyperpigmentation of difficult management. The condition was controlled with systemic corticosteroid therapy and finasteride. Lichen planus pigmentosus is an uncommon variant of lichen planus frequently associated with frontal fibrosing alopecia in darker phototipes. It should be considered in patients affected by scarring alopecia with a pattern of lichen planopilaris and areas of skin hyperpigmentation revealing perifollicular hyperpigmentation refractory to multiple treatments. This case illustrates diagnostic and therapeutic challenge in face of scarring alopecia and perifollicular hyperpigmentation. PMID:29267454

Promising alternative clinical uses of prostaglandin F2α analogs: beyond the eyelashes.

PubMed

Choi, Young M; Diehl, Joseph; Levins, Paul C

2015-04-01

Prostaglandin F2α analogs, commonly prescribed for glaucoma treatment, have been shown to induce side effects such as cutaneous hypertrichosis and hyperpigmentation. Therefore, these medications have theoretic applications in the treatment of alopecia and disorders of hypopigmentation. We reviewed the literature to find original studies assessing the use of prostaglandin F2α analogs in these settings. Studies and reports were analyzed in regards to androgenic alopecia, alopecia areata, chemotherapy-induced alopecia, vitiligo, and hypopigmented scarring. Based on the results of these studies, and consideration of pathophysiologic mechanism, the most promising applications for prostaglandin F2α analogs include androgenic alopecia, chemotherapy-induced alopecia, and alopecia areata concurrently treated with corticosteroids.

308-nm excimer laser for the treatment of alopecia areata in children.

PubMed

Al-Mutairi, Nawaf

2009-01-01

Alopecia areata (AA) is a common skin disease which is characterized by nonscarring localized or diffused hair loss. In this study we assessed the efficacy of 308-nm Excimer laser in the treatment of alopecia areata in children. A total of 9 children with 30 recalcitrant patches alopecia areata and two children with alopecia areata totalis were enrolled in this study which included seven male and four female patients, aged between 4 and 14 years and the durations of their disease were between 7 and 25 months. All of these patients had more than one lesion of alopecia areata and at least one of them was left as a control for comparison. The lesions were treated with the 308-nm Excimer laser twice a week for a period of 12 weeks. Regrowth of hair was observed in 18 (60%) alopecia patches in the scalp, while there was no response in the control patches and over the extremities. Only four patients with scalp lesions showed a recurrence of alopecia after 6 months post laser therapy. So, 308-nm Excimer laser is considered an effective safe therapeutic option for patchy alopecia areata in children.

Drugs - Do we need them? Applications of non-pharmaceutical therapy in anterior eye disease: A review.

Natural products have been in use long before the introduction of modern drug therapies and are still used in various communities worldwide for the treatment of anterior eye disease. The aim of this review is to look at the current non-pharmaceutical modalities that have been tried and assess the body of existing evidence behind them. This includes alternative medicine, existing non-pharmaceutical therapy and more recent low and high tech solutions. A detailed search of all available databases including MEDLINE, Pubmed and Google was made to look for English-language studies for complementary and alternative treatment modalities (CAM), natural therapies and new modalities for anterior eye disease such as blepharitis, dry eye and microbial keratitis. We have included a broad discussion ranging from traditional treatments like honey and aloe vera which have been used for centuries, to the more recent technological advances like Intense Pulsed Light (IPL), LipiFlow and photoactivated chromophore for corneal cross linking in infectious keratitis (PACK-CXL). Alternative management strategies may have a role in anterior eye diseases and have a potential in changing the way we currently approach them. Some of the available CAM could play a role if incorporated in to current management practices of not only chronic diseases like blepharitis and dry eye, but also acute conditions with significant morbidity like microbial keratitis. Further large-scale randomized control trials stratified by disease severity are required to improve our understanding and to evaluate the use of non-pharmaceutical therapy against current practice.

Naked Hair Shafts as a Marker of Cicatricial Alopecia.

PubMed

Doytcheva, Kristina; Tan, Timothy; Guitart, Joan; Gerami, Pedram; Yazdan, Pedram

2018-07-01

Naked hair shafts (NHS) are free-floating hair shafts devoid of surrounding epithelium, supporting structures, and/or embedded in inflammation that may result from destruction of hair follicles by scarring processes such as inflammation and fibroplasia. Extensive examination of NHS has not been performed in scalp biopsies of alopecia. We retrospectively evaluated 622 scalp biopsies of alopecia [345 cicatricial alopecias (central centrifugal cicatricial alopecia, lichen planopilaris, discoid lupus erythematosus, acne keloidalis nuchae, and folliculitis decalvans] and 277 non-cicatricial alopecias [alopecia areata, androgenic alopecia, telogen effluvium, and psoriatic alopecia)] for the presence of NHS. NHS occurred in 0.72% (2/277) of non-cicatricial alopecias (1/102 of alopecia areata, 1/150 of androgenic alopecia, 0/17 of telogen effluvium, and 0/8 of psoriatic alopecia) and 20% (72/345) of cicatricial alopecias (27/118 of central centrifugal cicatricial alopecia, 29/109 of lichen planopilaris, 2/75 of discoid lupus erythematosus, 11/16 of acne keloidalis nuchae, and 3/27 of folliculitis decalvans). The presence of NHS was significantly increased in cicatricial alopecias in comparison with non-cicatricial alopecias; P value <0.0001. Among the cicatricial alopecias, 26% (92/345) had mild inflammation and/or fibrosis, of which 9% (9/92) had NHS. There were 73% (253/345) that had moderate to severe inflammation and/or fibrosis, of which 24% (63/253) had NHS, indicating that as the severity of inflammation and fibrosis increases, so does the presence of NHS. NHS rarely occurs in non-cicatricial alopecias. This variation may result from destruction of hair follicles by the inflammatory and scarring processes. The presence of NHS may be a useful adjunctive histopathologic feature in the diagnosis of cicatricial alopecia.

Canine visceral leishmaniasis (CVL) diagnosis is still a challenge in endemic areas with limited diagnostic resources. This study proposes a score with the potential to distinguish positive CVL cases from negative ones. We studied 265 dogs that tested positive for CVL on ELISA and parasitological tests. A score ranging between 0 and 19 was recorded on the basis of clinical signs. Dogs with CVL had an overall higher positivity of the majority of clinical signs than did dogs without CVL or with ehrlichiosis. Clinical signs such as enlarged lymph nodes (83.93%), muzzle/ear lesions (55.36%), nutritional status (51.79%), bristle condition (57.14%), pale mucosal colour (48.21%), onychogryphosis (58.93%), skin lesion (39.28%), bleeding (12.50%), muzzle depigmentation (41.07%), alopecia (39.29%), blepharitis (21.43%), and keratoconjunctivitis (42.86%) were more frequent in dogs with CVL than in dogs with ehrlichiosis or without CVL. Moreover, the clinical score increased according to the positivity of all diagnostic tests (ELISA, p < 0.001; parasite culture, p = 0.0021; and smear, p = 0.0003). Onychogryphosis (long nails) [odds ratio (OR): 3.529; 95% confidence interval (CI): 1.832-6.796; p < 0.001], muzzle depigmentation (OR: 4.651; 95% CI: 2.218-9.750; p < 0.001), and keratoconjunctivitis (OR: 5.400; 95% CI: 2.549-11.441; p < 0.001) were highly associated with CVL. Interestingly, a score cut-off value ≥ 6 had an area under the curve of 0.717 (p < 0.0001), sensitivity of 60.71%, and specificity of 73.64% for CVL diagnosis. The clinical sign-based score for CVL diagnosis suggested herein can help veterinarians reliably identify dogs with CVL in endemic areas with limited diagnostic resources. PMID:28076469

Alopecia secondary to mesotherapy.

2009-10-01

Mesotherapy has recently become an advertised method for the treatment of different types of alopecia despite the lack of any data regarding its efficacy and possible side effects. The substances injected into the scalp include "cocktails" of natural plant extracts, homoeopathic agents, vitamins, vasodilators, and drugs that may stimulate hair growth, such as finasteride and minoxidil. We report two cases of patchy alopecia that developed after mesotherapy for the treatment of androgenetic alopecia. In the first patient, alopecia developed after injections of the heparinoid vasodilator mesoglycan; the 3-month follow-up examination revealed a small residual area of cicatricial alopecia. The second patient developed reversible alopecia after multiple scalp injections of homeopathic agents. These cases underline the possible risks of mesotherapy as a therapeutic technique for hair loss.

Alopecia areata universalis in a dog.

Alopecia areata is a T-cell mediated autoimmune disease that occurs in humans and various other mammalian species. When the disease progresses to total alopecia it is defined as alopecia areata universalis (AAU), although this outcome has only been described in humans. To describe a case of canine alopecia areata universalis and its clinical outcome after 22 months of follow-up. A 9-year-old intact male cross-breed hunting dog was presented with generalized and complete noninflammatory alopecia of 12-14 months duration. Clinical examination; histopathological and immunohistochemical examination of skin biopsies. There was loss of all body hair including eyelashes and vibrissae. The histopathological and immunohistochemical findings supported a diagnosis of long-standing alopecia areata. Treatment with oral ciclosporin was associated with hair regrowth but muzzle hair, most eyelashes and whiskers were still lacking after 17 months of therapy. To the best of the author's knowledge this is the first documented case of canine AAU. The clinical and histopathological features were consistent with a diagnosis of AAU as defined in humans. Treatment with oral ciclosporin resulted in near complete resolution of the alopecia, but after 5 months without treatment the alopecia did not relapse and spontaneous resolution cannot be ruled out. © 2015 ESVD and ACVD.

Alopecia in four kittens caused by abnormal maternal licking behaviour.

PubMed

Fanton, N; Michelazzi, M; Cornegliani, L

2015-11-01

Abnormal maternal behaviour has been reported in cats, but is generally not included among the causes of alopecia in kittens. A litter of four kittens, 2 months old, was referred for evaluation of facial alopecia of differing severity. The 2-year-old queen was unaffected. Dermatological examination of the kittens did not find any infectious cause. Trichograms showed broken hair shafts with longitudinal splitting. Congenital alopecia was unlikely based on the clinical presentation. A behavioural consultation revealed abnormal grooming behaviour by the mother, who chewed and removed the hair from the kittens. The kittens were separated from the queen and alopecia resolved within a few weeks. To the authors' knowledge, this is the first report of alopecia caused by abnormal maternal licking behaviour. Abnormal maternal behaviour should be considered in cases of alopecia affecting a litter of kittens, when infectious and congenital causes have been ruled out. © 2015 Australian Veterinary Association.

Occipital alopecia following cardiopulmonary bypass.

PubMed

Lwason, N W; Mills, N L; Ochsner, J L

1976-03-01

Postoperative alopecia is a minor complication of surgery but a cosmetic disaster to the patient. Over a 3 year period, 60 cases of occipital alopecia were discovered in patients following open-heart surgery and 5 cases on other surgical services. In contrast to previous reports, 29 patients had alopecia one year later, presumed to be permanent. Extensive operations, with prolonged recovery and elective overnight mechanical ventilation, were common to all. Retrospective analysis and prospective studies clearly demonstrated that localized scalp pressure was the cause of the alopecia and that the duration of pressure determined the extent of the damage. Moving the patient's head at regular intervals during operation and recovery eliminated the alopecia. The type of head rest used did not modify the development of alopecia. Electrical injury and the use of heparin, hypothermia, electrocautery, or hypotension were eliminated as possible causes. Conclusive evidence correlating periperative events with the formation of pressure sores in man has not been previously reported.

2016-12-01

To describe a case of testicular neoplasia and alopecia universalis in a dog, and successful treatment of the latter with ciclosporin. Twelve-year-old intact male wirehaired fox terrier. Castration, skin biopsy for histopathology, lymphocyte immunophenotyping and clonality analysis of the canine T-cell receptor gamma locus (TCRγ) rearrangement. The dog presented with symmetrical generalized alopecia. Testicular enlargement was noted which on castration was determined to be caused by bilateral interstitial cell tumours, Sertoli cell tumours and a unilateral seminoma. During the four months after castration the alopecia became more severe and widespread. Histopathology of the skin showed moderate, multifocal, mural folliculitis, peribulbar mucinosis and lymphocytic bulbitis, and targeting of anagen hair follicles. Immunophenotyping of the infiltrate showed a population of well-differentiated, small CD3-positive T lymphocytes, some expressing CD4 and others CD8. Molecular analysis revealed a polyclonal lymphocytic infiltrate, substantiating the diagnosis of alopecia areata rather than lymphoma. Treatment with ciclosporin (4.6 mg/kg) and ketoconazole (4.6 mg/kg) resulted in complete hair regrowth. Ciclosporin treatment, in combination with ketoconazole, can be effective for treatment of alopecia universalis in the dog. Alopecia universalis may present with clinically noninflammatory, symmetrical, generalized alopecia, mimicking an endocrine alopecia, and skin biopsies are needed to confirm the diagnosis. © 2016 ESVD and ACVD.

Female pattern hair loss.

PubMed

Ioannides, Dimitrios; Lazaridou, Elizabeth

2015-01-01

Female pattern hair loss, or female pattern androgenetic alopecia, is a nonscarring alopecia with a multi-factorial etiology that mostly affects postmenopausal women and is characterized by a reduction in hair density over the crown and frontal scalp. The clinical picture is characterized by a diffuse rarefaction of scalp hair over the mid-frontal scalp and a more-or-less intact frontal hairline without any signs of inflammation or scarring. Although the disease poses only a cosmetic concern, it is chronic and may have a significant negative psychological impact on the affected person. The aim of treating female pattern hair loss is to reduce hair loss and, to a certain extent, succeed in promoting hair regrowth. Various treatment methods are available, but it remains unclear which are the most effective. Early initiation of treatment and the combination of various modalities seem to be more efficacious than monotherapy. © 2015 S. Karger AG, Basel.

Kheirkhah, Ahmad; Blanco, Gabriela; Casas, Victoria; Tseng, Scheffer C G

2007-07-01

To show whether fluorescein dye helps detect and count Demodex embedded in cylindrical dandruff (CD) of epilated eyelashes from patients with blepharitis. Two eyelashes with CD were removed from each lid of 10 consecutive patients with blepharitis and subjected to microscopic examination with and without fluorescein solution to detect and count Demodex mites. Of 80 eyelashes examined, 36 (45%) lashes retained their CD after removal. Before addition of the fluorescein solution, the mean total Demodex count per patient was 14.9 +/- 10 and the mean Demodex count per lash was 3.1 +/- 2.5 and 0.8 +/- 0.7 in epilated eyelashes with and without retained CD, respectively (P < 0.0001). After addition of the fluorescein solution, opaque and compact CD instantly expanded to reveal embedded mites in a yellowish and semitransparent background. As a result, the mean total Demodex count per patient was significantly increased to 20.2 +/- 13.8 (P = 0.003), and the mean count per lash was significantly increased to 4.4 +/- 2.8 and 1 +/- 0.8 in eyelashes with and without retained CD (P < 0.0001 and P = 0.007), respectively. This new method yielded more mites in 8 of 10 patients and allowed mites to be detected in 3 lashes with retained CD and 1 lash without retained CD that had an initial count of zero. Addition of fluorescein solution after mounting further increases the proficiency of detecting and counting mites embedded in CD of epilated eyelashes.

A Practical Approach to the Diagnosis and Management of Hair Loss in Children and Adolescents

PubMed Central

Xu, Liwen; Liu, Kevin X.; Senna, Maryanne M.

2017-01-01

Hair loss or alopecia is a common and distressing clinical complaint in the primary care setting and can arise from heterogeneous etiologies. In the pediatric population, hair loss often presents with patterns that are different from that of their adult counterparts. Given the psychosocial complications that may arise from pediatric alopecia, prompt diagnosis and management is particularly important. Common causes of alopecia in children and adolescents include alopecia areata, tinea capitis, androgenetic alopecia, traction alopecia, trichotillomania, hair cycle disturbances, and congenital alopecia conditions. Diagnostic tools for hair loss in children include a detailed history, physical examination with a focused evaluation of the child’s hair and scalp, fungal screens, hair pull and tug test, and if possible, light microscopy and/or trichoscopy. Management of alopecia requires a holistic approach including psychosocial support because treatments are only available for some hair loss conditions, and even the available treatments are not always effective. This review outlines the clinical presentations, presents a diagnostic algorithm, and discusses management of these various hair loss disorders. PMID:28791288

Treatment of alopecia areata with 308-nm excimer lamp.

2010-12-01

Alopecia areata is considered to be a T-cell mediated autoimmune disorder. The 308-nm excimer lamp is thought to be capable of inducing T-cell apoptosis in vitro, suggesting that the lamp might be effective for the treatment of alopecia areata. We examined the effectiveness of the 308-nm excimer lamp for the treatment of alopecia areata. We recruited three patients with single alopecia areata lesions that were resistant to conventional treatment. The lesions were exposed to a 308-nm excimer lamp at 2-weekly intervals. Hair regrowth was observed in all three patients after approximately 10 treatment sessions. Our study showed that exposure to the 308-nm excimer lamp effectively induced hair regrowth in solitary alopecia areata lesions. Apart from erythema, there were no significant adverse effects. Therefore, we suggest that it may be considered as a treatment modality for recalcitrant alopecia areata. © 2010 Japanese Dermatological Association.

Successful treatment of alopecia areata-like hair loss with the contact sensitizer squaric acid dibutylester (SADBE) in C3H/HeJ mice.

1999-07-01

A type of hair loss closely resembling human alopecia areata has been described in C3H/HeJ mice. In order to test the assumed analogy with human alopecia areata, we investigated the efficacy of treatment with the contact allergen squaric acid dibutylester. In 12 C3H/HeJ mice with alopecia areata an allergic contact dermatitis was induced and elicited weekly on one side of the back by topical applications of squaric acid dibutylester. Overt hair regrowth was observed only on the treated side of the back in nine of 12 mice. Histopathologic examination revealed a change in the distribution of the inflammatory infiltrate from a dense perifollicular lymphocytic infiltrate around the mid and lower regions of hair follicles in untreated skin to a uniform presence in the upper dermis in treated skin. Immunohistomorphometric studies revealed that treatment with squaric acid dibutylester increased the CD4+/CD8+ ratio from approximately 1:2 in untreated alopecia areata to 1:1 in treated alopecia areata. Additional immunohistochemical investigations showed an aberrant expression of major histocompatibility complex class I, major histocompatibility complex class II and intercellular adhesion molecule 1 on keratinocytes of the mid and lower parts of hair follicles in untreated alopecia areata. In successfully treated skin ectopic major histocompatibility complex class I and II expression was clearly reduced, whereas intercellular adhesion molecule 1 expression showed only minor changes. In conclusion, alopecia areata-like hair loss in C3H/HeJ mice responded to treatment with the contact sensitizer squaric acid dibutylester analogous to human alopecia areata. Moreover, successful treatment changes the aberrant expression of major histocompatibility complex class I and II in a way similar to that observed in human alopecia areata. These observations support the concept that alopecia areata-like hair loss in C3H/HeJ mice can be utilized as an appropriate model for the study of human alopecia areata.

We sought to evaluate the safety and efficacy of the Janus kinase 1/3 inhibitor, tofacitinib, in a series of patients over an extended period of time. This is a retrospective study of patients age 18 years or older with AA with at least 40% scalp hair loss treated with tofacitinib. The primary end point was the percent change in Severity of Alopecia Tool (SALT) score during treatment. Ninety patients met inclusion criteria. Of 65 potential responders to therapy, defined as those with alopecia totalis or alopecia universalis with duration of current episode of disease of 10 years or less or alopecia areata, 77% achieved a clinical response, with 58% of patients achieving greater than 50% change in SALT score over 4 to 18 months of treatment. Patients with AA experienced a higher percent change in SALT score than did patients with alopecia totalis or alopecia universalis (81.9% vs 59.0%). Tofacitinib was well tolerated, and there were no serious adverse events. The retrospective nature of the data, the relatively small number of patients, and lack of a control group are limitations. Tofacitinib should be considered for the treatment of severe AA, alopecia totalis, and alopecia universalis; tofacitinib dose response will be better defined by randomized controlled trials.

Alopecia areata is an autoimmune disorder characterized by transient, non-scarring hair loss and preservation of the hair follicle. Hair loss can take many forms ranging from loss in well-defined patches to diffuse or total hair loss, which can affect all hair bearing sites. Patchy alopecia affecting the scalp is the most common type. Alopecia areata affects nearly 2% of the general population at some point during their lifetime. Skin biopsies of alopecia areata affected skin show a lymphocytic infiltrate in and around the bulb or the lower part of the hair follicle in anagen (hair growth) phase. A breakdown of immune privilege of the hair follicle is thought to be an important driver of alopecia areata. Genetic studies in patients and mouse models showed that alopecia areata is a complex, polygenic disease. Several genetic susceptibility loci were identified associated with signaling pathways that are important to hair follicle cycling and development. Alopecia areata is usually diagnosed based on clinical manifestations, but dermoscopy and histopathology can be helpful. Alopecia areata is difficult to manage medically, but recent advances in understanding the molecular mechanisms have revealed new treatments and the possibility of remission in the near future.

Background: Alopecia is one of the most important hair follicle (HF) disorders, which is divided into scarring (cicatricial) and nonscarring (noncicatricial) types. Objective: The aim of this study is to investigate the expression of stem cell (SC) markers such as cytokeratin (CK) 17 and CK19 in scarring and nonscarring alopecia. Materials and Methods: Thirty patients with scalp alopecia (15 with scarring alopecia and 15 without) together with ten healthy volunteers were included in this study. Biopsies were taken from all participants and stained for CK17 and CK19 using immunohistochemistry. Results: There was a statistically significant difference between the nonscarring group and the control group with regard to CK17 expression in the outer layers of the HFs (P = 0.00) and CK19 staining of the inner layers of the HFs (P = 0.008). There was a statistically significant difference between the scarring and the control groups regarding CK17 expression in the outer (P = 0.00) and the inner layers (P = 0.00) of the HFs and CK19 expression in the inner layers of the HFs (P = 0.00). CK17 expression in the outer layers (P = 0.02) and the inner layers of the HFs (P = 0.00) together with CK19 expression in the inner layers of the HFs (P = 0.00) showed statistically significant differences between scarring and nonscarring alopecia groups. Conclusions: The presence of SC markers (CK17 and CK19) in the HFs was affected in both scarring and nonscarring alopecia, but the defect in scarring alopecia is more evident than that of nonscarring alopecia. The persistence of SC markers in some types of scarring alopecia could give a hope for the recovery of these lesions. Further studies are recommended to clarify the benefit from using HF SCs in the treatment of alopecia. PMID:27761086

Canine visceral leishmaniasis (CVL) diagnosis is still a challenge in endemic areas with limited diagnostic resources. This study proposes a score with the potential to distinguish positive CVL cases from negative ones. We studied 265 dogs that tested positive for CVL on ELISA and parasitological tests. A score ranging between 0 and 19 was recorded on the basis of clinical signs. Dogs with CVL had an overall higher positivity of the majority of clinical signs than did dogs without CVL or with ehrlichiosis. Clinical signs such as enlarged lymph nodes (83.93%), muzzle/ear lesions (55.36%), nutritional status (51.79%), bristle condition (57.14%), pale mucosal colour (48.21%), onychogryphosis (58.93%), skin lesion (39.28%), bleeding (12.50%), muzzle depigmentation (41.07%), alopecia (39.29%), blepharitis (21.43%), and keratoconjunctivitis (42.86%) were more frequent in dogs with CVL than in dogs with ehrlichiosis or without CVL. Moreover, the clinical score increased according to the positivity of all diagnostic tests (ELISA, p < 0.001; parasite culture, p = 0.0021; and smear, p = 0.0003). Onychogryphosis (long nails) [odds ratio (OR): 3.529; 95% confidence interval (CI): 1.832-6.796; p < 0.001], muzzle depigmentation (OR: 4.651; 95% CI: 2.218-9.750; p < 0.001), and keratoconjunctivitis (OR: 5.400; 95% CI: 2.549-11.441; p < 0.001) were highly associated with CVL. Interestingly, a score cut-off value ≥ 6 had an area under the curve of 0.717 (p < 0.0001), sensitivity of 60.71%, and specificity of 73.64% for CVL diagnosis. The clinical sign-based score for CVL diagnosis suggested herein can help veterinarians reliably identify dogs with CVL in endemic areas with limited diagnostic resources.

Quantitative and ultrastructural analysis of inflammatory infiltrates in male pattern alopecia.

PubMed

Sueki, H; Stoudemayer, T; Kligman, A M; Murphy, G F

1999-09-01

In order to determine whether lymphocytic inflammation around the lower infundibula in male pattern alopecia is incidental or a general phenomenon, we performed morphometric and ultrastructural analysis of inflammatory infiltrates in the transitional zones of the vertex and occipital hairy scalps of 19 patients with male pattern alopecia. Six normal subjects served as controls. The number of inflammatory infiltrates around the follicular infundibula of the alopecic vertices and non-alopecic occiputs of male pattern alopecia patients was significantly greater than the corresponding control value. The number of mast cells in the widened fibrous tracts in the vertices of male pattern alopecia patients was significantly greater than those in the adventitial fibrotic sheaths of control subjects and the non-alopecic occiputs of male pattern alopecia patients. These data support the idea that the inflammatory process may be, at least in part, responsible for the development of male pattern alopecia.

Traction alopecia: the root of the problem.

PubMed

Billero, Victoria; Miteva, Mariya

2018-01-01

Traction alopecia (TA) affects one-third of women of African descent who wear various forms of traumatic hairstyling for a prolonged period of time. The risk of TA is increased by the extent of pulling and duration of traction, as well as the use of chemical relaxation. The frequent use of tight buns or ponytails, the attachment of weaves or hair extensions, and tight braids (such as cornrows and dreadlocks) are believed to be the highest risk hairstyles. TA can also occur in the setting of religious and occupational traumatic hairstyling. In its later stages, the disease may progress into an irreversible scarring alopecia if traumatic hairstyling continues without appropriate intervention. The most common clinical presentation includes marginal alopecia and non-marginal patchy alopecia. A clue to the clinical diagnosis is the preservation of the fringe sign as opposed to its loss in frontal fibrosing alopecia (FFA). Dermoscopy can be helpful in the diagnosis and can detect the ongoing traction by the presence of hair casts. Histopathology can distinguish TA from alopecia areata, FFA, and patchy central centrifugal cicatricial alopecia. Currently, there is no cure. Therefore, it is imperative that clinicians educate high-risk populations about TA and those practices that may convey the risk of hair loss.

In order to prevent Adriamycin (ADM)-induced alopecia, scalp hypothermia with a Duncool-Cap frozen in a freezer at -70 degrees C was carried out. Of the 18 patients studied, one patient given total ADM doses of 240 mg developed alopecia of moderate degree, and another patient treated with ADM at a dose level of 50 mg developed mild alopecia. Alopecia could be almost completely prevented in 10 of the 11 patients given total ADM doses of 100 mg or less, and in 6 of the 7 patients given total doses of 200 mg or more.

In this article we describe a 39-year-old man who presented with non-scarring non-scalp alopecia of his limbs as the initial presentation of sarcoidosis. Alopecia is a rare cutaneous manifestation of sarcoidosis. A literature review has found only one other example of sarcoidosis presenting as non-scarring non-scalp alopecia in an area other than the scalp in a patient who was otherwise asymptomatic. Several reported cases have described scarring alopecia of the scalp, which is the area of skin most commonly affected by sarcoidosis. There has been one documented case of sarcoidosis manifesting as total body non-scarring alopecia in a patient who had systemic symptoms of sarcoidosis. Other cases have presented rare cutaneous manifestations of sarcoidosis but in all these cases several other organ systems have been involved, and the patient has had systemic symptoms on presentation or the cutaneous presentation did not include non-scalp non-scarring alopecia. © 2015 The Australasian College of Dermatologists.

Previous studies have shown that androgenic alopecia is associated with metabolic syndrome and diabetes. However, the detailed mechanism whereby diabetes causes alopecia still remains unclear. We focused on the inflammatory response that is caused by diabetes or obesity, given that inflammation is a risk factor for hair loss. Inducible nitric oxide synthase (iNOS) is known to be upregulated under conditions of acute or chronic inflammation. To clarify the potential role of iNOS in diabetes-related alopecia, we generated obese diabetic iNOS-deficient (ob/ob; iNOS-KO mice). We observed that ob/ob; iNOS-KO mice were potentiated for the transition from telogen (rest phase) to anagen (growth phase) in the hair cycle compared with iNOS-proficient ob/ob mice. To determine the effect of nitric oxide (NO) on the hair cycle, we administered an iNOS inhibitor intraperitoneally (compound 1400 W, 10 mg/kg) or topically (10% aminoguanidine) in ob/ob mice. We observed that iNOS inhibitors promoted anagen transition in ob/ob mice. Next, we administered an NO donor (S-nitrosoglutathione, GSNO), to test whether NO has the telogen elongation effects. The NO donor was sufficient to induce telogen elongation in wild-type mice. Together, our data indicate that iNOS-derived NO plays a role in telogen elongation under the inflammatory conditions associated with diabetes in mice. Copyright © 2018 The Authors.

Alopecia areata is an autoimmune skin disease resulting in the loss of hair on the scalp and elsewhere on the body. The disease most often occurs in childhood and affects males and females of all ages. The National Alopecia Areata Foundation conducts research summits every 2 years to review progress and create new directions in its funded and promoted research. The Foundation brings together scientists from all disciplines to get a broad and varied perspective. These summits are part of the Foundation's main strategic initiative, the Alopecia Areata Treatment Development Program to accelerate progress toward a viable alopecia areata treatment.

Alopecia areata is a common autoimmune disorder that leads to nonscarring hair loss. Black dots, also called comedo-like cadaver hairs, can be found in almost 50% of alopecia areata patients and indicate disease activity. Trichostasis spinulosa is a follicular disorder resulting from the retention of numerous hairs surrounded by a keratinous sheath in dilated follicles. Trichostasis spinulosa is a relatively common but underdiagnosed disorder of hair follicles. Here, we describe a man with alopecia areata of the eyebrows, androgenetic alopecia and trichostasis spinulosa at the vertex and show how dermoscopy can be useful in distinguishing black dots from Trichostasis spinulosa lesions.

Human immunodeficiency virus (HIV) causes impairment to the human immune system which leads to immunocompromised conditions, including ocular complications. Several important HIV-associated disorders may involve the anterior segment, ocular surface, and adnexae organ such as dry eye, blepharitis which reduce quality of life of patients. In present, potent antiretroviral therapies HAART (highly active antiretroviral therapy) has improved the length and quality of life which may lead to an increased prevalence of anterior segment ocular disorders. Hence, this study has been undertaken to identify the prevalence and associated factors of anterior segment and external ocular disorder in HIV infected patients in the era of HAART. A prospective descriptive cross sectional study was carried out in HIV positive patients conducted at the Department of Ophthalmology, Chiang Mai University Hospital, from February 2014 to October 2015. Detail history and ocular examination was carried out to examine for anterior segment and external ocular disorders. A total number of 363 patients were included for this prospective cross-sectional study. From the total of 363 patients, 123 patients had an anterior segment and external ocular disorder which account as the prevalence of 33.9%. The most common anterior segment manifestations was dry eye seen in 36 patients (9.9%), followed by posterior blepharitis (Meibomian gland dysfunction) seen in 23 patients (6.3%) and anterior blepharitis seen in 12 patients (3.3%). Other ocular complications included microvasculopathy, immune recovery uveitis, conjunctivitis, papilloma, anterior uveitis, corneal ulcer, nevus, trichiasis, molluscum contangiosum, Kaposi sarcoma, interstitial keratitis, conjunctival lymphangiectasia, dacryocystitis, vernal keratoconjunctivitis and eyelid penicilosis. In this study, the prevalance of anterior segment disorders was higher than in the preHAART era. Dry eye, blepharitis and uveitis were the top three most common anterior segment disorders in the HAART era. The statistical analysis showed no association between age, sex, CD4 count, duration of infection or receiving HAART and anterior segment disorders. Anterior segment abnormalities reduce the quality of life of patients, so ophthalmologists have to be aware and complete ocular examination should be performed in all HIV infected patients.

Alopecia areata is loss of hair from localized or diffuse areas of hair-bearing area of the skin. Recently there are reports of efficacy of the 308-nm excimer radiation for this condition. To study the effect of the 308-nm excimer laser in the treatment of alopecia areata. Eighteen patients with 42 recalcitrant patches (including 1 adult with alopecia totalis) were enrolled in this study. The lesions were treated with the 308-nm excimer laser twice a week for a period of 12 weeks; one lesion on each patient was left as a control for comparison. There were 7 males and 11 females in this study. Regrowth of hair was observed in 17 (41.5%) patches. Thirteen of the 18 lesions in scalp showed a complete regrowth of hair. The extremity regions failed to show a response. Atopic diatheses had an unfavorable effect on the outcome in our patients. The 308-nm excimer laser is an effective therapeutic option for patchy alopecia areata of the scalp and for some cases with patchy alopecia areata of the beard area. It does not work for patchy alopecia areata of the extremities.

Effect of Cuscuta reflexa Roxb on androgen-induced alopecia.

Alopecia is a psychologically distressing condition. Androgenetic alopecia, which affects millions of men and women, is an androgen-driven disorder. Here, Cuscuta reflexa Roxb is evaluated for hair growth activity in androgen-induced alopecia. Petroleum ether extract of C. reflexa was studied for its hair growth-promoting activity. Alopecia was induced in albino mice by testosterone administration for 20 days. Its inhibition by simultaneous administration of extract was evaluated using follicular density, anagen/telogen ratio, and microscopic observation of skin sections. To investigate the mechanism of observed activity, in vitro experiments were performed to study the effect of extract and its major component on activity of 5alpha-reductase enzyme. Petroleum ether extract of C. reflexa exhibited promising hair growth-promoting activity as reflected from follicular density, anagen/telogen ratio, and skin sections. Inhibition of 5alpha-reductase activity by extract and isolate suggest that the extract reversed androgen-induced alopecia by inhibiting conversion of testosterone to dihydrotestosterone. The petroleum ether extract of C. reflexa and its isolate is useful in treatment of androgen-induced alopecia by inhibiting the enzyme 5alpha-reductase.

Hair is a body appendage that throughout history has been a symbol of the social, cultural and political climate, in addition to connoting religious affiliation. Hair loss on the other hand has been associated with a loss of attractiveness, individuality, a state of disgrace and illness, in addition to the ageing process, death and a loss of sexuality. One of the most common side-effects of chemotherapy is hair loss (alopecia). Alopecia can range from sporadic thinning of the hair to complete baldness. Several factors may contribute to the severity of hair loss including drug, dose and schedule as well as hair care practices. Prevention of alopecia has been a focus in the medical and nursing literature since the late 1960s. Mechanical, physical and biological measures have been used with varying success. The goal of prevention is primarily the reduction of patient distress caused by chemotherapy-induced alopecia. Patient reactions to alopecia vary and may be dependent on the individual importance of hair, prognosis, degree of expected hair loss, the amount of information and preparation given, and physical and psychological coping mechanisms. Nurses play an important role in assisting the patient to cope with alopecia by giving the needed information and teaching self-care strategies to minimize alopecia, cope with alopecia, and protect the skin and eyes following alopecia. These interventions are aimed at helping the patient move through a potentially devastating experience to a renewed sense of well-being.

The side effects of mesotherapy for treatment of various forms of alopecia are often underreported, while scientific data for its efficacy are severely lacking. To demonstrate the late onset side effects of mesotherapy for alopecia. Three patients with androgenetic alopecia showed hair loss after previously uneventful mesotherapy sessions up to 1 year. Clinical, dermoscopic, and histopathological findings suggested an inflammatory scaring process at sites of mesotherapy injections. Mesotherapy for androgenetic alopecia may paradoxically induce hair loss and scarring. Proper regulation and monitoring of the use of mesotherapy products for treating hair loss in women, needs to be addressed. © 2017 Wiley Periodicals, Inc.

Assessment of the usefulness of dihydrotestosterone in the diagnostics of patients with androgenetic alopecia

PubMed Central

Urysiak-Czubatka, Izabela; Broniarczyk-Dyła, Grażyna

2014-01-01

Introduction Androgenetic alopecia (AGA) is the most common form of hair loss. Clinically observed hair loss is due to the continuous miniaturization of affected hair follicles. Genetic factors and androgenic factors especially dihydrotestosterone (DHT), which is a testosterone tissue metabolite, play major roles in the pathogenesis of AGA. However, expert opinions about the usefulness of DHT in the diagnosis of this type of alopecia are divided. Aim To evaluate the usefulness of DHT level in patients with androgenetic alopecia compared with the control group. Material and methods The study comprised 49 subjects: 19 women and 9 men with androgenetic alopecia. The control group consisted of 17 healthy women and 4 men without hair loss. Results Increased serum concentrations of DHT were observed in patients with androgenetic alopecia (17 women, 5 men), but also in the control group. The differences in mean values of DHT were not significant according to the types of alopecia and the control group. Increased serum concentrations of DHT were not correlated with the advance of alopecia. Conclusions Dihydrotestosterone is the most influential androgen and seems to play a very important role in the pathogenesis of androgenetic alopecia. Based on the results of our study and others, the most important factors would appear to be the genetically-determined sensitivity of the follicles to DHT and their different reactions to androgen concentration.

Alopecia: Kids are not just little people.

PubMed

Goldberg, Lynne J; Castelo-Soccio, Leslie A

2015-01-01

Alopecia is a disorder that affects all patients, young and old. Many diagnoses, particularly the scarring alopecias, are more common in adults; however, others, such as tinea capitis, are more common in children, and some, such as alopecia areata, often affect both age groups. The approach to, and evaluation of, an alopecia patient is thus highly dependent on his or her age. In adults with diffuse, non-scarring hair loss, a part-width examination can help detect pattern hair loss, the most common cause of diffuse loss in this age group. In children this is much less likely, and a careful evaluation for tinea capitis is in order. The same holds true for patchy alopecia in children, as well as scarring alopecia-tinea needs to always be considered. In adults, patchy alopecia is often due to alopecia areata and sometimes to one of the primary scarring alopecias. A laboratory evaluation, and especially a biopsy, would be a more appropriate undertaking for an adult than a child, and an adult would be more likely to tolerate certain therapeutic regimens such as intralesional injections. In a conversational manner, the authors discuss their individual approaches to the alopecia patient, highlighting the differences in diagnosis, workup, and management that depend on whether the affected individual is an adult or a child.

Since the 1980s, laser technology has become increasingly popular to treat a variety of cutaneous conditions. Its successful use as an epilator comes with the rare but interesting side effect of paradoxical hypertrichosis. In this review, we summarize cases describing hair growth after photoepilation, as well as studies testing laser and light sources as treatment for alopecia, particularly androgenetic alopecia and alopecia areata. We also discuss the possible biologic mechanisms by which phototherapy induces hair regeneration.

Alopecia areata is a common hair loss condition that is often emotionally devastating for patients. There is a paucity of effective treatments available. Hydroxychloroquine has been reported as variably effective in inducing significant hair regrowth in adults with alopecia areata. The objective of this retrospective study was to assess the benefit and tolerability of hydroxychloroquine in pediatric alopecia areata. We conducted a retrospective review of nine children with a history of alopecia areata treated with hydroxychloroquine. Clinical data were obtained from patients treated at two tertiary care centers in the United States between July 1, 2013, and July 1, 2015. Alopecia scores of five patients improved by 6 months of treatment. Four patients experienced no improvement from baseline evaluation. The most common side effect associated with treatment was gastrointestinal intolerance and headache. This retrospective series suggests that hydroxychloroquine can be considered as a treatment option for alopecia areata in children. © 2018 Wiley Periodicals, Inc.

Two sika deer from a zoo in Florida were examined because of chronic hair loss and skin lesions. No common causes of alopecia were identified in either deer. One deer was treated with prednisone, but the condition worsened when the dosage was decreased. Both deer were euthanatized after several months because of continued disease. The predominant histologic lesion in skin specimens was granulomatous mural folliculitis. Serologic testing and sequencing of fragments produced with a consensus polymerase chain reaction assay indicated that both deer were infected with caprine herpesvirus-2, a newly recognized member of the malignant catarrhal fever group of viruses. Disease in these deer was substantially different from that typically seen following infection with ovine herpesvirus-2, the sheep-associated malignant catarrhal fever virus. Findings in these deer establish the pathogenicity of caprine herpesvirus-2 in sika deer and illustrate the ability of this group of complex herpesviruses to cause a wide variety of clinical abnormalities in diverse species.

The authors tried to verify the efficacy of Low Power Laser (LPL) in scalp alopecia and crural ulcers of different causes. Laser used was (red diode, continuous emission, 8 mW power, wave length 670 nm spot size about 5 mm diameter on some points 1 - 2 minutes per point. We also use as control classical therapy. Before, during and after treatment, histological samples were done for alopecia. For laser groups (alopecia and ulcers) the results were rather superior and in a three or twice time shorter than control group. We conclude that LPL therapy is a very useful complementary method for the treatment of scalp alopecia and crural ulcers.

Anagen effluvium with reversible scalp alopecia is a known side effect of chemotherapy. However, there are an increasing number of reports in the literature documenting permanent alopecia in patients treated with taxanes. We sought to describe the clinicopathologic features in breast cancer patients who underwent treatment with taxanes and adjuvant hormonal chemotherapy. We reviewed the clinical and histopathologic information of a cohort of 10 patients treated with taxanes and adjuvant hormonal chemotherapy. We have observed 3 types of clinical patterns of alopecia (types A, B, and C), and have validated the histopathologic features showing alopecia areata-like and female pattern hair loss. The study was based on a small sample size and retrospective retrieval of clinical information and histopathologic review of posttreatment slides. We hypothesize a clinicopathologic model of hair follicle cycle disruption in response to the chemoinflammatory and hormonal insults to the hair follicles resulting in permanent alopecia. Clinicopathologic correlation is paramount to the understanding of the morphobiologic pathways in chemotherapy-induced alopecia caused by taxanes and adjuvant hormonal treatment.

Muller, David C; Giles, Graham G; Sinclair, Rod; Hopper, John L; English, Dallas R; Severi, Gianluca

2013-02-01

Both prostate cancer and androgenetic alopecia are strongly age-related conditions that are considered to be androgen dependent, but studies of the relationship between them have yielded inconsistent results. We aimed to assess whether androgenetic alopecia at ages 20 and 40 years are associated with risk of prostate cancer. At a follow-up of the Melbourne Collaborative Cohort Study, men were asked to assess their hair pattern at ages 20 and 40 years relative to eight categories in showcards. Cases were men notified to the Victorian Cancer Registry with prostate cancer diagnosed between cohort enrollment (1990-1994) and follow-up attendance (2003-2009). Flexible parametric survival models were used to estimate age-varying HRs and predicted cumulative probabilities of prostate cancer by androgenetic alopecia categories. Of 9,448 men that attended follow-up and provided data on androgenetic alopecia, we identified 476 prostate cancer cases during a median follow-up of 11 years four months. Cumulative probability of prostate cancer was greater at all ages up to 76 years, for men with vertex versus no androgenetic alopecia at age of 40 years. At age of 76 years, the estimated probabilities converged to 0.15. Vertex androgenetic alopecia at 40 years was also associated with younger age of diagnosis for prostate cancer cases. Vertex androgenetic alopecia at age of 40 years might be a marker of increased risk of early-onset prostate cancer. If confirmed, these results suggest that the apparently conflicting findings of previous studies might be explained by failure to adequately model the age-varying nature of the association between androgenetic alopecia and prostate cancer.

Alopecia areata is an immune-dependent disorder characterized by the interaction of T-lymphocytes with follicular antigens. Recent studies have shown the existence of a local renin-angiotensin system in the skin, where angiotensin-converting enzyme (ACE) plays a role in autoimmunity and inflammation. The objective of this study was to evaluate serum and tissue ACE activity in patients with alopecia areata. This case-control study was conducted on patients with alopecia areata and healthy controls. Serum and tissue ACE activity were assessed and compared between the two groups. Twenty-five alopecia areata patients (60% male, mean age 32.1 ± 9.9 years) and 24 controls (50% male, mean age 37.4 ± 8.8 years) were included. Mean serum ACE activity was 52.1 ± 9 U/L in cases and 55.3 ± 14.7 U/L in controls (P = 0.37). Tissue ACE activity was significantly lower in cases in all parts of the skin i.e. epidermis (P = 0.016), follicular epithelium (P = 0.004), and endothelium (P = 0.037). Among cases, serum ACE activity was significantly higher in patients with more severe disease (P = 0.030), nonpatchy alopecia areata (alopecia universalis; ophiasis, patchy and ophiasis, diffuse) (P = 0.029), and with nail involvement (P = 0.027). The sample size was too small to draw definite conclusions. Further, most of the patients had only mild or moderate alopecia areata. Unlike in some other inflammatory diseases, the tissue level of ACE seems to be significantly lower in alopecia areata compared to normal controls. Serum ACE was significantly higher in patients with more severe disease.

Can long-term alopecia occur after appropriate pulsed-dye laser therapy in hair-bearing sites? Pediatric dermatologists weigh in.

2015-03-01

The risk of long-term alopecia after pulsed-dye laser (PDL) therapy is unknown. To identify how many practitioners treat hair-bearing sites with PDL and how commonly long-term alopecia occurs, the authors queried pediatric dermatologists about their experiences using this modality. A survey was designed to evaluate the frequency of and factors contributing to long-term alopecia after PDL treatment of port-wine stains (PWS). "Long-term" was defined as no sign of hair regrowth after several years of nontreatment. The survey was administered to attendees at the 2014 Society for Pediatric Dermatology biannual meeting. Sixty-four pediatric dermatologists completed the survey, 50 of whom had experience using PDL. Of these physicians, 86% have used PDL to treat PWS of the eyebrow and 80% have treated PWS of the scalp. Over one-quarter of respondents (25.5%) using PDL on hair-bearing areas had at least 1 of their patients develop long-term alopecia after PDL treatment. The incidence of long-term alopecia after PDL treatment in the surveyed population was 1.5% to 2.6%. The occurrence of long-term alopecia at hair-bearing sites after treatment with PDL may be greater than previously thought. Because the majority of physicians using PDL treat hair-bearing areas, prospective studies are needed to more accurately determine the risk of long-term alopecia and the factors that contribute to it.

Trichoscopy (hair and scalp dermoscopy) analyzes the structure and size of growing hair shafts, providing diagnostic clues for inherited and acquired causes of hair loss. Types of hair shaft abnormalities observed include exclamation mark hairs (alopecia areata, trichotillomania, chemotherapy-induced alopecia), Pohl-Pinkus constrictions (alopecia areata, chemotherapy-induced alopecia, blood loss, malnutrition), comma hairs (tinea capitis), corkscrew hairs (tinea capitis), coiled hairs (trichotillomania), flame hairs (trichotillomania), and tulip hairs (in trichotillomania, alopecia areata). Trichoscopy allows differential diagnosis of most genetic hair shaft disorders. This article proposes a classification of hair shaft abnormalities observed by trichoscopy. Copyright © 2013.

Alopecia is a common form of hair loss which can occur in many different conditions, including male-pattern hair loss, polycystic ovarian syndrome, and alopecia areata. Alopecia can also occur as a side effect of chemotherapy in cancer patients. In this study, our goal was to develop a consistent and reliable method to quantify hair loss in mice, which will allow investigators to accurately assess and compare new therapeutic approaches for these various forms of alopecia. The method utilizes a standard gel imager to obtain and process images of mice, measuring the light absorption, which occurs in rough proportion to the amount of black (or gray) hair on the mouse. Data that has been quantified in this fashion can then be analyzed using standard statistical techniques (i.e., ANOVA, T-test). This methodology was tested in mouse models of chemotherapy-induced alopecia, alopecia areata and alopecia from waxing. In this report, the detailed protocol is presented for performing these measurements, including validation data from C57BL/6 and C3H/HeJ strains of mice. This new technique offers a number of advantages, including relative simplicity of application, reliance on equipment which is readily available in most research laboratories, and applying an objective, quantitative assessment which is more robust than subjective evaluations. Improvements in quantification of hair growth in mice will improve study of alopecia models and facilitate evaluation of promising new therapies in preclinical studies.

Hair breakage as a presenting sign of early or occult central centrifugal cicatricial alopecia: clinicopathologic findings in 9 patients.

2012-09-01

Central centrifugal cicatricial alopecia is the most common form of cicatricial alopecia in African American women. Treatment options are limited and mostly aimed at halting further hair loss but rarely result in hair regrowth. Therefore, it is important to recognize early clinical signs, perform a confirmatory biopsy, and begin treatment promptly. We have observed that hair breakage may be a key sign of early central centrifugal cicatricial alopecia, and this association is not clearly described in the literature. Nine patients with hair breakage on the vertex with or without scalp symptoms underwent scalp biopsies as part of their evaluation. Of these, 8 had histologic samples adequate for complete interpretation: 5 specimens (63%) showed histologic changes typical of central centrifugal cicatricial alopecia, with 1 of these showing advanced end-stage changes of cicatricial alopecia. Two (25%) revealed premature desquamation of the inner root sheath as the sole finding suggestive of early central centrifugal cicatricial alopecia and 1 (13%) was normal. Although hair breakage can have multiple causes, early central centrifugal cicatricial alopecia must be considered in the differential diagnosis, particularly in women of African ancestry. Histologic evaluation may reveal early or late findings that can help establish the diagnosis.

Treating Alopecia Areata: Current Practices Versus New Directions.

Gupta, Aditya K; Carviel, Jessie; Abramovits, William

Alopecia areata (AA) is non-scarring hair loss resulting from an autoimmune disorder. Severity varies from patchy hair loss that often spontaneously resolves to severe and chronic cases that can progress to total loss of scalp and body hair. Many treatments are available; however, the efficacy of these treatments has not been confirmed, especially in severe cases, and relapse rates are high. First-line treatment often includes corticosteroids such as intralesional or topical steroids for mild cases and systemic steroids or topical immunotherapy with diphenylcyclopropenone or squaric acid dibutylester in severe cases. Minoxidil and bimatoprost may also be recommended, usually in combination with another treatment. Ongoing research and new insights into mechanisms have led to proposals of innovative therapies. New directions include biologics targeting immune response as well as lasers and autologous platelet-rich plasma therapy. Preliminary data are encouraging, and it is hoped this research will translate into new options for the treatment of AA in the near future.

Alopecia: Possible Causes and Treatments, Particularly in Captive Nonhuman Primates

Alopecia (hair loss) occurs in some nonhuman primates housed in captivity and is of concern to colony managers and veterinarians. Here we review the characteristics, potential causes, and treatments for this condition. Although we focus on nonhuman primates, relevant research on other mammalian species is discussed also, due to the relative paucity of studies on alopecia in the primate literature. We first discuss the cycle of hair growth and explain how this cycle can be disrupted to produce alopecia. Numerous factors may be related to hair loss and range from naturally occurring processes (for example, seasonality, aging) to various biologic dysfunctions, including vitamin and mineral imbalances, endocrine disorders, immunologic diseases, and genetic mutations. We also address bacterial and fungal infections, infestation by parasites, and atopic dermatitis as possible causes of alopecia. Finally, we examine the role of psychogenic factors, such as stress. Depending on the presumed cause of the hair loss, various treatment strategies can be pursued. Alopecia in nonhuman primates is a multifaceted disorder with many potential sources. For this reason, appropriate testing for various disease conditions should be completed before alopecia is considered to be related to stress. PMID:19295051

A modified double blind crossover study was performed to assess the effect of 1% topical minoxidil as compared with placebo in 30 patients with alopecia areata and alopecia totalis. The active preparation produced a highly significant incidence of hair regrowth. A cosmetically acceptable response was noted in 16 patients. No side effects were seen. The study confirmed that topical minoxidil will induce new hair growth in alopecia areata but that it is less likely to do so in more severe and extensive disease. Furthermore, patients with alopecia universalis and totalis may not respond at all. Nevertheless, as compared with other drugs minoxidil applied topically is relatively non-toxic, is easy to use, and has no systemic or local side effects. Images p1016-a PMID:6412929

2018-03-01

Alopecia areata is a form of nonscarring hair loss that occurs in pediatric and adult patients, with presentation varying from round or ovoid patches of alopecia to alopecia totalis or universalis. While frustrating for patients, it can also be frustrating for clinicians to treat, as there is no definitive treatment. Dermatologists are very familiar with the use of methotrexate for psoriasis and other inflammatory skin diseases, and this medication is generally well tolerated in children. This study presents a case series reviewing the efficacy of methotrexate in our pediatric patients with alopecia areata, making use of a retrospective chart review design from 2011 to 2016. In this data set, 8/14 subjects (57%) experienced good regrowth with methotrexate, while 3/14 (21%) had a response that could not be assessed due to loss to follow-up or premature discontinuation of the medication. No cases discontinued the medication due to recognized methotrexate side effects. This review suggests methotrexate is a generally safe and often effective medication in pediatric alopecia areata.

This study explored the perceived effects of an aesthetic care/wig programme for Italian women suffering from chemotherapy-induced alopecia. Despite advances in the treatment of many side effects of chemotherapy, alopecia remains difficult to resolve. Literature suggests that patients' reactions to alopecia and camouflaging strategies depend on their gender, individual characteristics, social context, and culture. A qualitative study was designed involving 20 patients from Sicily (Italy), who participated in an aesthetic care programme. Data were collected through semi-structured interviews, and an Interpretative Phenomenological Analysis was conducted on transcriptions. Our findings showed that, even if expected, alopecia is experienced as a traumatic event that challenges a woman's femininity, as reported by many other enquiries. Diverging from other studies, the wig is perceived as very helpful, since it camouflages baldness and reduces the 'sick aspect' related to alopecia. Patients consider their wig to be a 'friend', and it appears that through the aesthetic care programme they received support they otherwise would not have sought. We conclude that aesthetic care/wig programmes can help women affected by alopecia to cope with cancer 'stigma', especially in those rural contexts where psychosocial programmes are not frequently embraced by patients due to environmental and cultural barriers. © 2012 Blackwell Publishing Ltd.

2017-12-11

Alopecia is a common disease affecting more than half of the world total number of people. Alopecia exists in different types, but one of the most common of these types is the Androgenic Alopecia which has affected approximately 51% of the total number of males ranging between the age bracket of 40 years and 75 years. This type of alopecia is more common in females who are above the age of 65 years and above. Despite this widespread effect, much has not been done regarding identifying the possible drugs for treating this disease. At present, there exist only two possible medications that have been scientifically approved to cure this disease, include finasteride and minoxidil. Also, another possible form of treatment has been the case of hair transplantation. Despite the new possible treatment options available for treatment of different types of hair loss, there is a need for the invention for more efficient management and treatment options that are less costly, environmentally friendly, and most importantly human consumption friendly. Due to the recent evaluation that low-level laser therapy stimulated hair growth. This systematic review and meta-analysis was to determine whether the use of low-level laser therapy is an effective therapy for treatment of the Androgenic alopecia and also to some degree we reviewed the level of the patient's satisfaction. Some earlier studies had shown that the use of low-level laser therapy stimulated the hair growth when mice were treated with chemotherapy which was induced by the alopecia and also the other type of alopecia called alopecia areata. The researchers hypothesized that the primary mechanism of treating Androgenic alopecia to be the stimulation of the epidermal stem cells which are in the hair follicle making them bulge and shift the follicles into the anagen phase.

Demodecidosis is an ectoparasitosis of pilosebaceous unit caused by demodex mites. The disease may be a primary skin disease or a secondary disease to inflammatory dermatoses such as folliculitis and rosacea. Demodex spp. blepharitis is an infectious ocular disease that is common but always neglected. These mites contain lipase enzymes that help carry bacteria on the surface. The infestation of Demodex spp. has increasingly become a public health concern. A 29-year-old male patient was admitted to our dermatology clinic with a complaint of papules and pustules on his face, which started 4 years ago. A standardized skin biopsy specimen was evaluated in our microbiology laboratory, and we detected Demodex folliculorum mites on his face (3+). There was pruritus of his eyes. A total of four eyelashes were epilated and were then examined under a light microscope for the presence of Demodex infestation. In this study, we discussed the association between acne rocacea, blepharitis, and demodex mites.

2015-01-01

Background Trichoscopic findings of hair loss have been well described for the differential diagnosis of alopecia; however, critical findings were not thoroughly investigated or compared among all ethnic groups, including Asians. Objective We aimed to find any characteristic trichoscopic findings in Korean alopecia patients and to verify whether those findings are closely related to previously reported observations. Methods Three hundred and twenty-seven patients with hair loss of various causes and 160 normal scalps were analyzed. Trichoscopic examination was performed with a polarized-light handheld dermoscope. Results A total of 35 patterns of trichoscopic features were represented, and certain features were significantly common or observed exclusively in a particular type of alopecia as follows: yellow dots, exclamation mark hairs, and proximal tapering hairs (alopecia areata), trichoptilosis and pointed hairs (trichotillomania), corkscrew hairs, septate hyphae hairs, and comma hairs (tinea capitis), diffuse white area, fibrotic white dots, and tufting hairs (primary cicatricial alopecia), hair diameter diversity and peripilar sign (androgenetic alopecia), and short nonvellus hairs (telogen effluvium). Conclusion The characteristic trichoscopic features for the differential diagnosis of alopecia in Koreans, shown as follicular, perifollicular, and hair shaft patterns, are similar to those of Caucasians; however, the frequencies of the pigment patterns are different between Koreans and Caucasians because of the contrast effect of the skin and hair color. Therefore, racial difference should be considered in the trichoscopic evaluation for differential diagnosis. PMID:26512168

Development of a disease-specific instrument to measure quality of life in patients with alopecia areata.

2012-01-01

Alopecia areata (AA) is a common hair loss disorder that frequently follows a chronic course. Although AA is apparently associated with disturbance of quality of life (QoL), no disease-specific instrument to measure the QoL has been developed. This study was conducted to develop a disease-specific self-administered instrument to measure AA patients' QoL (AAQ). A two-step cross-sectional study was conducted. Items were generated from qualitative interviews with five patients with AA (two men and three women, age 28±6.4 years). Then, a preliminary questionnaire was produced and delivered to the patients (n=122). The AAQ was examined in terms of statistical performance. The AAQ included 7 items in the following three subscales: 'restriction of activity', 'concealment' and 'adaptation'. The reliability of internal consistency was fair with Cronbach's alpha coefficients of 0.59-81 for each subscale. Confirmatory factor analysis and correlation analysis demonstrated that the AAQ had good construct validity. Interestingly, the AAQ was only correlated with subjective severity scores as rated by the patients, but not with objective disease severity assessed by investigators.

Objective To assess the clinical safety and tolerability of a novel MGO Manuka Honey microemulsion (MHME) eye cream for the management of blepharitis in human subjects. Methods and analysis Twenty-five healthy subjects were enrolled in a prospective, randomised, paired-eye, investigator-masked trial. The MHME eye cream (Manuka Health New Zealand) was applied to the closed eyelids of one eye (randomised) overnight for 2 weeks. LogMAR visual acuity, eyelid irritation symptoms, ocular surface characteristics and tear film parameters were assessed at baseline, day 7 and day 14. Expression of markers of ocular surface inflammation (matrix metalloproteinase-9 and interleukin-6) and goblet cell function (MUC5AC) were quantified using impression cytology at baseline and day 14. Results There were no significant changes in visual acuity, eyelid irritation symptoms, ocular surface characteristics, tear film parameters and inflammatory marker expression during the 2-week treatment period in treated and control eyes (all p>0.05), and measurements did not differ significantly between eyes (all p>0.05). No major adverse events were reported. Two subjects experienced transient ocular stinging, presumably due to migration of the product into the eye, which resolved following aqueous irrigation. Conclusion The MHME eye cream application was found to be well tolerated in healthy human subjects and was not associated with changes in visual acuity, ocular surface characteristics, tear film parameters, expression of markers of inflammation or goblet cell function. The findings support future clinical efficacy trials in patients with blepharitis. Trial registration number ACTRN12616000540415 PMID:29354710

The aim of the present study was to provide more information on the role of illness perception in patients with androgenetic alopecia (AGA) and those with alopecia areata (AA), and to further investigate the relationship of illness perception with psychological disorders and dermatological QoL. The study included 342 patients who were diagnosed with AGA (n=212) or AA (n=130) for the first time at our institution between October 2013 and December 2014. All patients were surveyed before clinical examination by several questionnaires including the Brief Illness Perception, Self-rating Depression Scale, Self-rating Anxiety Scale, and Dermatology Life Quality Index (DLQI). In the AGA patients, the illness perception and QoL were low, whereas the prevalence of clinical depression and anxiety was higher compared to the AA patients. Illness perception was associated with psychological distress and low QoL in both groups, and some illness perception dimensions were found to be significant predictors of the DLQI scores. Illness perception plays an important role in AGA and AA patients, and is associated with psychological distress and low QoL. The identification of critical components of illness perception in alopecia patients could help to understand alopecia specificities, to design consultations and interventions according to the perception, and to improve physical and mental outcomes as well as QoL in alopecia patients.

Exacerbation of alopecia areata: A possible complication of sodium tetradecyl sulphate foam sclerotherapy treatment for varicose veins.

PubMed

Whiteley, Mark S; Smith, Victoria C

2017-01-01

A 40-year-old woman with a history of alopecia areata related to stress or hormonal changes was treated for bilateral primary symptomatic varicose veins (CEAP clinical score C2S) of pelvic origin, using a staged procedure. Her first procedure entailed pelvic vein embolisation of three pelvic veins using 14 coils and including foam sclerotherapy of the tributaries, using 3% sodium tetradecyl sulphate. Following this procedure, she had an exacerbation of alopecia areata with some moderate shedding of hair. Subsequently, she underwent endovenous laser ablation under local anaesthetic without incident. Seven months after the pelvic vein embolisation, she underwent foam sclerotherapy of leg and labial varicose veins using sodium tetradecyl sulphate. Two days following this procedure, she had a severe exacerbation of alopecia areata with gross shedding of hair. These two episodes of exacerbation of alopecia areata appear to be associated with sodium tetradecyl sulphate foam sclerotherapy of veins.

Industry Perspective on Alopecia Areata.

2015-11-01

Recent advances in our understanding of the autoimmune basis of alopecia areata provide an opportunity to create novel effective pharmaceutical interventions. The current lack of approved therapies for alopecia areata presents a high unmet medical need, as well as a potentially attractive market opportunity. From an industry perspective, achieving clinical proof of concept (PoC) gates investments into larger approval studies. Recent investigator-initiated experience suggests that it may be possible to demonstrate rigorous PoC for new therapies in an attractive time frame with relatively fewer patients than were believed necessary in the past. However, the lack of prior regulatory approval precedent for pharmaceuticals to treat alopecia areata poses significant development challenges, and early interaction with the FDA and other stakeholders will be critically important in evaluating the path to approval and reimbursement for new treatments for this indication. This paper presents a brief industry perspective on the potential development of new alopecia areata therapeutics.

A 43-year-old man was admitted to our hospital because of diplopia, ptosis, and dysphagia that had begun three years previously. He was diagnosed with myasthenia gravis (MG) and invasive thymoma and treated with corticosteroid, thymectomy, and radiation therapy. Ten years after the thymectomy, computed tomography (CT) showed metastasis of the thymoma in the left lower lobe of the lung. Two years after this recurrence, when the patient was 55, respiratory symptoms such as wheezing, persistent cough, and dyspnea appeared. Chronic sinusitis, diffuse centrilobular opacities on CT, and positivity for HLA-B54 led to a diagnosis of diffuse panbronchiolitis (DPB). Despite treatment with clarithromycin, the respiratory symptoms worsened. The patient developed alopecia and body hair loss at the age of 56 followed by dysgeusia, cholangitis, and myositis with positivity for anti-Kv1.4 antibodies. Although treatment with an increased dose of corticosteroid improved hair loss, dysgeusia, cholangitis, and myositis, he died of progression of DPB and serious respiratory infection at the age of 58. In this case, various autoimmune disorders occurred together with MG as complications of thymoma. Although alopecia, dysgeusia, and myositis are already known as complications of MG associated with thymoma, cholangitis is not well-recognized since there have been few reports suggesting a causal relationship between cholangitis and thymoma. Furthermore, DPB caused by immunodeficiency and respiratory tract hypersensitivity associated with thymoma and HLA-B54, respectively, is the distinctive feature of our case. Neurologists should be aware that various organs can be damaged directly and indirectly by abnormal T cells from thymoma in patients with MG.

Minoxidil (Mx) is known to induce hair growth in men with male-pattern baldness. Based on this potential, the effectiveness of Mx 2% topical solution was evaluated in cancer patients (pts) to prevent doxorubicin-induced alopecia. 48 female pts with different types of solid tumors treated with doxorubicin-based chemotherapy in a dose range of 50-60 mg/m2/cycle were randomly assigned to receive Mx 2% topical solution or placebo. 88% and 92% of pts in both arms showed severe alopecia (p = ns). No adverse effects were observed. In this study Mx 2% topical solution was non-toxic but was not effective in the prevention of chemotherapy-induced alopecia.

Differences in reproductive toxicology between alopecia drugs: an analysis on adverse events among female and male cases

2016-01-01

Alopecia is a dermatological condition with limited therapeutic options. Only two drugs, finasteride and minoxidil, are approved by FDA for alopecia treatment. However, little is known about the differences in adverse effects between these two drugs. We examined the clinical reports submitted to the FDA Adverse Event Reporting System (FAERS) from 2004 to 2014. For both female and males, finasteride was found to be more associated with reproductive toxicity as compared to minoxidil. Among male alopecia cases, finasteride was significantly more concurrent with several forms of sexual dysfunction. Among female alopecia cases, finasteride was significantly more concurrent with harm to fetus and disorder of uterus. In addition, drug-gene network analysis indicated that finasteride could profoundly disturb pathways related to sex hormone signaling and oocyte maturation. These findings could provide clues for subsequent toxicological research. Taken together, this analysis suggested that finasteride could be more liable to various reproductive adverse effects. Some of these adverse effects have yet to be warned in FDA-approved drug label. This information can help improve the treatment regimen of alopecia and post-marketing regulation of drug products.

2017-11-01

Hair loss stemming from different types of alopecia, such as androgenic alopecia and alopecia areata, negatively affects over half the population and, in many circumstances, causes serious psychosocial distress. Current treatment options for alopecia, such as minoxidil, anthralin, and intralesional corticosteroids, vary efficacy and side effect profiles. It is known that low-level laser/light therapies (LLLT), or photobiomodulations, such as the US FDA-cleared HairMax Lasercomb®, He-Ne laser, and excimer laser, are relatively affordable, user-friendly, safe, and effective forms of treatment for hair loss. While less is known about the effectiveness of fractional lasers for combating hair loss, research suggests that by creating microscopic thermal injury zones, fractional lasers may cause an increase in hair growth from a wound healing process, making them potential therapeutic options for alopecia. A literature review was performed to evaluate the effectiveness of fractional lasers on hair regrowth. The specific fractional laser therapies include the 1550-nm nonablative fractional erbium-glass laser, the ablative fractional 2940-nm erbium:YAG laser, and the ablative fractional CO 2 fractional laser. Additional randomized controlled trials are necessary to further evaluate the effectiveness of the lasers, as well as to establish appropriate parameters and treatment intervals.

The aim of this study was to approach on a psychical point of view 27 patients suffering from chronic idiopathic urticaria (14), pruritus sine materia (6), alopecia areata (3), pathomimia (4), in order to examine the possibility that psychic disorders could act as triggering or aggravating the dermatological affection. Psychical assessment was evaluated by colloquy and by the administration of some psychodiagnostic tests: EPI, MMPI, Zung. The role of psychogenic factors in skin diseases is emphasized and the results obtained from the use of antidepressant and minor tranquilizer drugs are discussed.

Recent Advances in the Pathogenesis of Autoimmune Hair Loss Disease Alopecia Areata

PubMed Central

2013-01-01

Alopecia areata is considered to be a cell-mediated autoimmune disease, in which autoreactive cytotoxic T cells recognize melanocyte-associated proteins such as tyrosinase. This review discusses recent advances in the understanding of the pathogenesis of alopecia areata, focusing on immunobiology and hormonal aspects of hair follicles (HFs). The HF is a unique “miniorgan” with its own immune and hormonal microenvironment. The immunosuppressive milieu of the anagen hair bulb modulated by immunosuppressive factors is known as “hair follicle immune privilege.” The collapse of the hair follicle immune privilege leads to autoimmune reactions against hair follicle autoantigens. Alopecia areata is sometimes triggered by viral infections such as influenza that causes excess production of interferons (IFN). IFN-γ is one of the key factors that lead to the collapse of immune privilege. This paper reviews the interactions between the endocrine and immune systems and hair follicles in the pathogenesis of alopecia areata. PMID:24151515

VIEWPOINT – Vitiligo and alopecia areata: Apples and oranges?

PubMed Central

Harris, John E.

2013-01-01

Vitiligo and alopecia areata are common autoimmune diseases of the skin. Vitiligo is caused by the destruction of melanocytes and results in the appearance of white patches on any part of the body, while alopecia areata is characterized by patchy hair loss primarily on the scalp, but may also involve other areas as well. At first glance, the two diseases appear to be quite different, targeting different cell types and managed using different treatment approaches. However, the immune cell populations and cytokines that drive each disease are similar, they are closely associated within patients and their family members, and vitiligo and alopecia areata have common genetic risk factors, suggesting that they share a similar pathogenesis. Like apples and oranges, vitiligo and alopecia areata have some obvious differences, but similarities abound. Recognizing both similarities and differences will promote research into the pathogenesis of each disease, as well as the development of new treatments. PMID:24131336

Treatments options for alopecia.

Hair disorders have a very high social and psychological impact. Treatment is often frustrating and time-consuming both for the patients and the clinicians and requires special skills and expertise. This paper aims to provide an overview of available treatments for the most common forms of alopecia in adults (androgenetic alopecia [AGA], alopecia areata and cicatricial alopecias) after reviewing the literature in PubMed, Google Scholar and ClinicalTrial.gov. Before starting treatment, it is very important to confirm diagnosis and discuss patient's expectations. Treatment of hair disorders requires time and first results are usually visible a few months after beginning of therapy. Treatment of most hair disorders is mostly not evidenced-based as randomized controlled trials are available only for AGA.

Postmenopausal frontal fibrosing alopecia: a frontal variant of lichen planopilaris.

1997-01-01

Lichen planopilaris usually produces multifocal areas of scarring alopecia. Recently, a condition in postmenopausal women characterized by progressive frontal hairline recession associated with scarring has been described. Our purpose was to study the clinical and histopathologic features and results of treatment in a group of women with the frontal variant of lichen planopilaris and to compare the immunohistochemical profile of scalp biopsy specimens from this subset with that found in the multifocal variant of lichen planopilaris. The clinical data as well as the histopathologic findings in 16 women with frontal fibrosing alopecia were collated. The immunohistochemical profile of six scalp biopsy specimens from the frontal hairline were compared with six specimens from women with multifocal lichen planopilaris. In addition to the progressive frontal fibrosing alopecia in all 16 women, total loss or a marked decrease of the eyebrows was observed in 13. No evidence of lichen planus was observed at other sites. In one patient multifocal areas of lichen planopilaris developed in the scalp. The frontal fibrosing alopecia was slowly progressive but has stabilized in five patients. Biopsy specimens from the frontal hairline showed histologic changes identical to lichen planopilaris. Immunophenotyping failed to reveal any significant differences between the frontal and multifocal variants. No effective treatments emerged although oral steroids and antimalarials may temporarily slow the course. Hormone replacement therapy did not appear to influence the course of the alopecia. Progressive frontal fibrosing alopecia is a clinically distinct variant of lichen planopilaris that affects in particular elderly women and frequently involves the eyebrows. The basis for this lichenoid tissue reaction targeting frontal scalp follicles and eyebrows is unknown.

Alopecia with perineural lymphocytes: a clue to linear scleroderma en coup de sabre.

Linear scleroderma en coup de sabre ('the stroke of the sword') is an uncommon form of morphea with onset typically in childhood or adolescence. Involvement is usually located on the paramedian forehead and is associated with alopecia. It is microscopically indistinguishable from other forms of scleroderma. We present a 51-year-old woman who presented with alopecia and subsequently developed linear scleroderma en coup de sabre on her adjacent forehead. Histopathology revealed a strikingly perineural lymphocytic and plasmacytic infiltrate, extending deeply into the subcutis and fascia. To our knowledge, this is the first report of alopecia with perineural lymphocytic inflammation as a presenting sign of linear scleroderma en coup de sabre. Copyright © 2012 John Wiley & Sons A/S.

The aim of the study was to carry out clinical and trichological examination (trichogram and assessment of hair loss) before and after treatment in 17 women aged 41-50 years with androgenic alopecia. Minoxidil (Loxon) was topically applied twice a day massaging the solution into the scalp over 6-12 months. It was revealed on the ground of clinical and trichological examination that the medication containing 2% solution of minoxidil externally applied on the scalp with androgenic alopecia over a few months caused normalization of hair root condition and decrease of hair loss in some patients of the observed group. The drug has a stimulating influence on hair growth and should be administered as an adjuvant therapy in androgenic alopecia in women.

Epidermal Cadm1 expression promotes autoimmune alopecia via enhanced T cell adhesion and cytotoxicity.

PubMed

Giangreco, Adam; Hoste, Esther; Takai, Yoshimi; Rosewell, Ian; Watt, Fiona M

2012-02-01

Autoimmune alopecia is characterized by an extensive epidermal T cell infiltrate that mediates hair follicle destruction. We have investigated the role of cell adhesion molecule 1 (Cadm1; Necl2) in this disease. Cadm1 is expressed by epidermal cells and mediates heterotypic adhesion to lymphocytes expressing class 1-restricted T cell-associated molecule (CRTAM). Using a murine autoimmune alopecia model, we observed an increase in early-activated cytotoxic (CD8-restricted, CRTAM-expressing) T cells, which preferentially associated with hair follicle keratinocytes expressing Cadm1. Coculture with Cadm1-transduced MHC-matched APCs stimulated alopecic lymph node cells to release IL-2 and IFN-γ. Overexpression of Cadm1 in cultured human keratinocytes did not promote cytokine secretion, but led to increased adhesion of alopecic cytotoxic T cells and enhanced T cell cytotoxicity in an MHC-independent manner. Epidermal overexpression of Cadm1 in transgenic mice led to increased autoimmune alopecia susceptibility relative to nontransgenic littermate controls. Our findings reveal that Cadm1 expression in the hair follicle plays a role in autoimmune alopecia.

Both vertical and transverse sections are used for the diagnosis of alopecia areata. However when a single biopsy is submitted the pathologist has to decide which type is better. To compare the diagnostic histological features in vertical and transverse sections in alopecia areata scalp biopsy specimens. Tertiary Care Hospital. Comparative Study. A total of 30 patients were enrolled in the study. Two four mm punch biopsy were taken. One was used to take vertical sections and the other for transverse section and histological features of alopecia areata noted in both. Chi-square test, percentage. Diagnosis of alopecia areata could be made in 30 (100%) cases in transverse sections and 28 cases (93.3%) in vertical sections. The number of hair follicles available for evaluation was more in the transverse section. Nanogen follicles and miniaturization of follicles were better visualized in the transverse sections. However the catagen and telogen follicles were noted in both vertical and transverse sections but the number and the ratio of anagen and telogen hair follicles could be better assessed in the transverse sections. Presence of peribulbar lymphocytic infiltrate, eosinophils and pigment casts were noted in both transverse and vertical sections. Transverse sections provide a better assessment of the histological features of alopecia areata than vertical sections and thus should be preferred.

Psoriatic alopecia - fact or fiction? A clinicohistopathologic reappraisal.

Silva, Claudine Yap; Brown, Katherine L; Kurban, Amal K; Mahalingam, Meera

2012-01-01

The incidence of psoriatic alopecia in psoriatic patients is underwhelming, given the prevalence of psoriasis in the North American population. Recently, a 60-year-old Albanian female, lacking a significant medical history for psoriasis, presented to our clinic with a 1-year history of "dandruff" associated with itch, hair thinning, and histopathologic evidence consistent with prior reports of "psoriatic alopecia." The absence of preceding or concomitant psoriasis suggests that the patient's alopecia is an antecedent manifestation of psoriasis, thus prompting this retrospective study to ascertain better the relationship between alopecia and psoriasis. We performed a retrospective review of 33 scalp biopsies on 31 patients having histopathologic diagnosis of psoriasis belonging to 31 patients seen between 2007 and 2010. Alopecia was a presenting feature in 48% of cases with definitive clinical and/or histopathologic diagnosis of psoriasis (scale crust with neutrophils, psoriasiform epidermal hyperplasia, and hypogranulosis). The most common follicular-related changes were infundibular dilatation (87%) followed by perifollicular fibrosis (77%), perifollicular lymphocytic inflammation (68%), thinning of the follicular infundibulum (55%), and fibrous tracts (28%). Of interest, sebaceous glands were absent in 60% and atrophic in 25% of cases. While a major limitation of this study is that it is a retrospective one, given that these changes are common to varying degrees in all lymphocytic scarring alopecias, we posit that psoriatic alopecia likely represents a secondary clinical change to a primary process and is not a unique histopathologic entity. A prospective study with a control group that includes lymphocytic scarring alopecias from non-psoriatic patients is required to support our findings.

Phototherapy for alopecia areata.

Welsh, Oliverio

2016-01-01

Phototherapy is a useful therapeutic method for various skin diseases due to its modulatory effect on the cutaneous immune system. Alopecia areata is a dermatosis characterized by partial or complete hair loss. Collapse of the immune privilege of the hair follicle, which induces noncicatricial alopecia, is an important factor in its etiology. Several forms of phototherapy are used in dermatology.

BACKGROUND Alopecia areata is an immune mediated inflammatory hair loss, which occurs in all ethnic and age groups, and both sexes. However no significant etiology has been known for this disease. Helicobacter pylori (H. pylori) , is an organism colonized in gastric mucosa. This bacterium has been associated with certain extra-digestive dermatological conditions. The causal relationship between alopecia areata and H. pylori infection has been discussed in literature. Therefore, we conducted this study to evaluate the prevalence of H. pylori infection in patients with alopecia areata and assess the risk of this infection in patients with this disease in order to determine its potential roles in the physiopathology of this disease. METHODS Between 2014 and 2015, we prospectively studied 81 patients with alopecia areata and 81 healthy volunteers with similar age and sex. Patients without any history of H. pylori infection were included in the study and underwent urease breath test. All results were analyzed using SPSS software (version 21.0) and p value<0.05 was considered as statistically significant. RESULTS 81 patients and 81 controls with the mean age of 34.9±11.6 and 38.2±13.4 years were studied (p=0.097). 48 (59.3%) and 45 (55.6%) individuals were male, in cases and control groups respectively (p =0.634). The result of urea breath test (UBT) was positive in 43 (53.1%) patients in cases and 27 (33.3%) individuals in control group, which was significantly different (p =0.011). The risk of H. pylori infection in alopecia areata was 2.263 (95% CI: 1.199-4.273). CONCLUSION The results of our study showed significant difference between H. pylori infection in individuals with and without alopecia areata, which shows that H. pylori contamination may be effective in physiopathology of alopecia areata. Therefore these results should be tested in large multivariable cohorts and controlled trials to reach more accurate evidence in the future and to generalize this idea to larger population.

Vertical vs. transverse sections of scalp biopsy specimens: a pilot study on the comparison of the diagnostic value of two techniques in alopecia.

Using both vertical and transverse sections is preferred for histopathological diagnosis of alopecia. However, in cases in which only a single biopsy is taken, it is not clear which type of sectioning is better. To compare the diagnostic value of transverse and vertical sections. In total, 53 patients with alopecia were enrolled in the study. Two biopsies were taken from each patient, and cut into either transverse or vertical sections. The clinical and histopathological findings were evaluated together for the definitive diagnosis. After the study period, a pathologist randomly re-evaluated the sections. We compared the histopathological diagnoses with the definitive diagnoses, and determined the sensitivity and specificity of each method. A definitive diagnosis was made for 47 patients (88.7%). Of these, 30 (63.8%) had noncicatricial and 17 (36.2%) had cicatricial alopecia, and the diagnosis was made by transverse and vertical sections for 43 (91.5%) and 39 (88%), respectively (P > 0.05; sensitivity; 91.5% vs. 82%). All 30 patients with noncicatricial alopecia were diagnosed by transverse sections, and 25 (83.3%) of the 30 were diagnosed with vertical sections (P = 0.05; sensitivity 100% vs. 83.3%). Of the 17 patients with cicatricial alopecia, 13 (76.5%) and 14 (82.4%) patients were diagnosed by transverse and vertical sections, respectively (P > 0.05; sensitivity 76.5% vs. 82.4%). Five patients with lichen planopilaris were diagnosed by vertical sections, and one by transverse sections. There were several limitations to the study: (i) statistical subtype analysis could be performed only for alopecia areata; (ii) no conclusion could be drawn about the interobserver reliability of two sections; and (iii) having the pathologist-blinded study performed retrospectively might have caused a recall bias. If only a single biopsy specimen is available, it may be preferable to have transverse sections in cases of suspected noncicatricial alopecia, and vertical sections in cases of suspected lichen planopilaris. Either type of sectioning is suitable for cicatricial alopecia when lichen planopilaris is clinically unlikely. © The Author(s). CED © 2011 British Association of Dermatologists.

Alopecia areata (AA) is a complex autoimmune condition that causes nonscarring hair loss. It typically presents with sharply demarcated round patches of hair loss and may present at any age. In this article, we review the epidemiology, clinical features, pathogenesis, and new treatment options of AA, with a focus on the immunologic mechanism underlying the treatment. While traditional treatment options such as corticosteroids are moderately effective, a better understanding of the disease pathogenesis may lead to the development of new treatments that are more directed and effective against AA. Sources were gathered from PubMed, Embase, and the Cochrane database using the keywords: alopecia, alopecia areata, hair loss, trichoscopy, treatments, pathogenesis, and epidemiology. PMID:29769777

Cutaneous and systemic lupus erythematosus (SLE) commonly involves the hair and scalp. Alopecia can result from direct activity of disease on the scalp or from the state of physical stress in the form of telogen effluvium. Discoid lupus erythematosus and lupus panniculitis/profundus are known to cause scarring alopecia, while accumulation of recent studies has shown that non-scarring alopecia in SLE may have different subtypes, comprising lupus erythematosus-specific and lupus erythematosus-nonspecific changes on histology. This review aims to summarize the clinical pattern, trichoscopic, histopathological, and direct immunofluorescence features of different types of alopecia in cutaneous and systemic lupus erythematosus, as well as exploring their relationship with SLE disease activity.

There is growing interest in alopecia among the general population. Many people obtain information from easily accessible media rather than from doctors; thus, the media can play an important role in shaping public opinion. The goal of this study was to evaluate the content and reliability of newspaper articles on alopecia. Newspapers were categorized into three groups: one group of print newspapers and two groups of online newspapers. Online newspapers were further divided into two groups according to type of publishing company; one publishes both print and online newspapers and the other publishes online newspapers only. The most frequently subscribed or circulated newspaper in each group was selected. Articles containing information on alopecia were selected from 3 years of each newspaper and evaluated for reliability. Most articles in each group used the general term "alopecia" instead of naming a specific hair loss disease. The majority of articles were based on consultation with experts. Assessment of the accuracy of articles with three grade scales showed that the percentage with high accuracy was 38.9%, 47.2%, and 23.3%. Assessment of reliability scores for five selected articles in each group showed that there were statistically significant differences between common readers and dermatologists ( p <0.05). The results of this study suggest that closer monitoring of the media is required to supply easily accessible, balanced, and trustworthy information regarding alopecia.

1994-01-01

We introduce cyclophosphamide-induced alopecia (CYP-IA) in C57BL-6 mice as a clinically relevant model for studying the biology of chemotherapy-induced alopecia and for developing anti-alopecia drugs. One injection of CYP to mice with all back skin follicles in anagen VI induces severe alopecia that strikingly reproduces the follicle response, recovery, and histopathology seen in human CYP-IA. CYP dose-dependently induces abnormal follicular melanogenesis and dystrophic anagen or, in more severely damaged follicles, dystrophic catagen. Both dystrophy forms are followed by an extremely shortened telogen phase, but differ in the associated hair loss and in recovery patterns, which determines hair regrowth. This follicular response to CYP can be manipulated pharmacologically: systemic cyclosporine A shifts it toward a mild form of dystrophic anagen, thus retarding CYP-IA and prolonging "primary recovery". Topical dexamethasone, in contrast, forces follicles into dystrophic catagen, which augments CYP-IA, but accelerates the regrowth of normally pigmented hair ("secondary recovery").

Alopecia areata is a common disease of unknown etiology; it causes significant cosmetic and psycho-social distress for most of the people it affects. We report on an innovative form of treatment in two patients with typical alopecia areata on the capillitium. We successfully treated two patients whose alopecia areata had worsened progressively for 3 and 14 weeks. The treatment involved the use of a 308 nm xenon chloride excimer laser (dosage 300-2,300 mJ/cm(2) per session). After 11 and 12 sessions within a 9-week and 11-week period, the entire affected focus showed homogenous and thick regrowth. No relapse was observed during the follow-up period of 5 and 18 months. The use of the excimer laser is an effective, elegant, and safe means of treatment and has good tolerability. Analogous to topical treatment of alopecia areata, the immunosuppressive mechanism of the excimer laser can be interpreted as an induction of T-cell apoptosis. This new means of treatment has yet to be discussed in medical literature. Further studies with greater numbers are needed to assess its potential more precisely and evaluate the excimer laser in treating alopecia areata. Copyright 2004 Wiley-Liss, Inc.

The aim of this study was to find out the effects of chemotherapy-related alopecia on body image and quality of life of Turkish women who have cancer with or without headscarves and factors affecting them. This descriptive study was conducted with 204 women who received chemotherapy at the Istanbul University Institute of Oncology, Turkey. The Patient Description Form, Body Image Scale and Nightingale Symptom Assessment Scale were used in data collection. Statistical analyses were performed using descriptive statistics and non-parametric tests. Logistic regression analysis was done to predict the factors affecting body image and quality of life of the patients. No difference was found between women wearing headscarves and those who did not in respect of their body image. However, women who wore headscarves who had no alopecia felt less dissatisfied with their scars, and women not wearing headscarves who had no alopecia have been feeling less self-conscious, less dissatisfied with their appearance. There was difference in terms of quality of life: women wearing headscarves had worse physical, psychological and general well-being than others. Although there were many important factors, multivariate analysis showed that for body image, having alopecia and wearing headscarves; and for quality of life, having alopecia were the variables that had considerable effects.

Tinea capitis in postpubertal patients is unusual and may be misdiagnosed as dissecting cellulitis. We report a case of a healthy 19-year-old Hispanic male presenting with a 2-month history of a large, painful subcutaneous boggy plaque on the scalp with patchy alopecia, erythematous papules, cysts and pustules. Although initially diagnosed as dissecting cellulitis, potassium hydroxide evaluation (KOH preparation) of the hair from the affected region was positive. A punch biopsy of the scalp demonstrated endothrix consistent with tinea capitis, but with a brisk, deep mixed inflammatory infiltrate as can be seen with chronic dissecting cellulitis. Fungal culture revealed Trichophyton tonsurans, and a diagnosis of inflammatory tinea capitis was made. The patient was treated over the course of 17 months with multiple systemic and topical antifungal medications, with slow, but demonstrable clinical and histopathological improvement. A rare diagnosis in adults, clinicians should have a high index of suspicion for this condition in an adult with an inflammatory scalp disorder not classic for dissecting cellulitis or with a recalcitrant dissecting cellulitis. Prompt, appropriate diagnosis and treatment is necessary to prevent the long-term complications of scarring alopecia. © 2013 Blackwell Verlag GmbH.

[Dapsone treatment of folliculitis decalvans].

Paquet, P; Piérard, G-E

Folliculitis decalvans consists of recurrent patchy painful folliculitis of the scalp causing scarring alopecia. The physiopathology of this condition is still unclear, but is likely a manifestation of chronic neutrophilic bacterial folliculitis. Numerous topical and systemic treatments (corticosteroids, antistaphylococcal antibiotics) have been used with variable results. Based on the dapsone antimicrobial activity and its anti-inflammatory action especially directed to the neutrophil metabolism, we treated two patients with severe folliculitis decalvans with this drug. The patients were treated with dapsone at a daily dose of 75 and 100 mg, respectively for 4 to 6 months. After 1 and 2 months, pustular folliculitis progressively cleared, leaving a residual non inflammatory cicatricial alopecia. When maintaining a dapsone dosage at 25 mg/day no relapse occurred during 3 years and 1 year, respectively. No important adverse effect to dapsone was evidenced. After dapsone withdrawal, a moderate relapse of the disease with pruritus and folliculitis occurred after a few weeks in both cases. The disease relapse rapidly cleared after dapsone reintroduction at a daily dose of 25 mg. Dapsone at moderate dosage was well tolerated and rapidly effective in treating the two cases of folliculitis decalvans. A long term and low dose (25 mg daily) maintenance treatment avoided disease relapses.

Purpose of review Vitiligo and alopecia areata are common, disfiguring skin diseases. Treatment options are limited and include non-targeted approaches such as corticosteroids, topical calcineurin inhibitors, narrow band UVB phototherapy, and other immune-modifying agents. The purpose of this article is to review shared, novel mechanisms between vitiligo and alopecia areata, as well as discuss how they inform the development of future targeted treatments. Recent findings Vitiligo and alopecia areata are both autoimmune diseases, and striking similarities in pathogenesis have been identified at the level of both the innate and adaptive immune system. Increased reactive oxygen species and high cellular stress level have been suggested as the initiating trigger of the innate immune system in both diseases, and genome-wide association studies have implicated risk alleles that influence both innate and adaptive immunity. Most importantly, mechanistic studies in mouse models of vitiligo and alopecia areata have specifically implicated an IFN-γ-driven immune response, including IFN-γ, IFN-γ-induced chemokines, and cytotoxic CD8+ T cells as the main drivers of disease pathogenesis. These recent discoveries may reveal an effective strategy to develop new treatments, and several proof-of-concept clinical studies support this hypothesis. Summary The identification of IFN-γ-driven immune signaling pathways has enabled discoveries of potential new treatments for vitiligo and alopecia areata, and supports initiation of larger clinical trials.

2016-01-01

Context: Both vertical and transverse sections are used for the diagnosis of alopecia areata. However when a single biopsy is submitted the pathologist has to decide which type is better. Aims: To compare the diagnostic histological features in vertical and transverse sections in alopecia areata scalp biopsy specimens. Settings and Design: Tertiary Care Hospital. Comparative Study. Materials and Methods: A total of 30 patients were enrolled in the study. Two four mm punch biopsy were taken. One was used to take vertical sections and the other for transverse section and histological features of alopecia areata noted in both. Statistical Analysis Used: Chi-square test, percentage. Results: Diagnosis of alopecia areata could be made in 30 (100%) cases in transverse sections and 28 cases (93.3%) in vertical sections. The number of hair follicles available for evaluation was more in the transverse section. Nanogen follicles and miniaturization of follicles were better visualized in the transverse sections. However the catagen and telogen follicles were noted in both vertical and transverse sections but the number and the ratio of anagen and telogen hair follicles could be better assessed in the transverse sections. Presence of peribulbar lymphocytic infiltrate, eosinophils and pigment casts were noted in both transverse and vertical sections. Conclusions: Transverse sections provide a better assessment of the histological features of alopecia areata than vertical sections and thus should be preferred. PMID:27625562

Background. Diagnosis of patchy hair loss in pediatric patients is often a matter of considerable debate among dermatologists. Trichoscopy is a rapid and noninvasive tool to detect more details of patchy hair loss. Like clinical dermatology, trichoscopy works parallel to the skin surface and perpendicular to the histological plane; like the histopathology, it thus allows the viewing of structures not discovered by the naked eye. Objective. Aiming to compare the different trichoscopic features of tinea capitis and alopecia areata in pediatric patients. Patients and Methods. This study included 40 patients, 20 patients with tinea capitis and 20 patients with alopecia areata. They were exposed toclinical examination, laboratory investigations (10% KOH and fungal culture), and trichoscope examination. Results. Our obtained results reported that, in tinea capitis patients, comma shaped hairs, corkscrew hairs, and zigzag shaped hairs are the diagnostic trichoscopic features of tinea capitis. While in alopecia areata patients, the most trichoscopic specific features were yellow dots, exclamation mark, and short vellus hairs. Conclusion. Trichoscopy can be used as a noninvasive tool for rapid diagnosis of tinea capitis and alopecia areata in pediatric patients. PMID:25024698

Immunological profiles in alopecia areata.

Cell-mediated immunity and auto-immune phenomena were investigated in sixty patients with active alopecia areata of various degrees of severity. Serum auto-antibodies to thyroid antigens were detected in twenty-three patients. Examination of T-lymphocyte populations, lymphocyte DNA synthesis, and lymphokine production in response to mitogen stimulation revealed no differences between the sixty patients and matched healthy control subjects. However, patients with thyroid auto-immunity and/or the presence of alopecia totalis or universalis showed significant reductions in interactive T lymphocytes (recognized by rosette formation with human B lymphoblastoid cells) and diminished production of leukocyte migration inhibition factor in response to stimulation with phytohaemagglutinin. This suggests that immune mechanisms may be involved in the pathogenesis of alopecia areata which is associated with thyroid auto-immunity or which progresses to total hair loss.

Alopecia (hair loss) is experienced by thousands of cancer patients every year. Substantial-to-severe alopecia is induced by anthracyclines (e.g., adriamycin), taxanes (e.g., taxol), alkylating compounds (e.g., cyclophosphamide), and the topisomerase inhibitor etoposide, agents that are widely used in the treatment of leukemias and breast, lung, ovarian, and bladder cancers. Currently, no treatment appears to be generally effective in reliably preventing this secondary effect of chemotherapy. We observed in experiments using different rodent models that localized administration of heat or subcutaneous/intradermal injection of geldanamycin or 17-(allylamino)-17-demethoxygeldanamycin induced a stress protein response in hair follicles and effectively prevented alopecia from adriamycin, cyclophosphamide, taxol, and etoposide. Model tumor therapy experiments support the presumption that such localized hair-saving treatment does not negatively affect chemotherapy efficacy. PMID:18347939

Dermoscopic clues to distinguish trichotillomania from patchy alopecia areata.

PubMed

Abraham, Leonardo Spagnol; Torres, Fernanda Nogueira; Azulay-Abulafia, Luna

2010-01-01

Trichotillomania and patchy alopecia areata have similar clinical and dermoscopic features. In trichotillomania, dermoscopy shows decreased hair density, short vellus hair, broken hairs with different shaft lengths, coiled hairs, short vellus hair, trichoptilosis, sparse yellow dots, which may or may not contain black dots and no exclamation mark hairs. In the case of patchy alopecia and broken hairs, the absence of exclamation mark hairs suggests a diagnosis of trichotillomania. On the other hand, the finding of yellow dots without black dots does not exclude it.

Herrmann, Anke; Bormann, Gisela; Marsch, Wolfgang Christian; Wohlrab, Johannes

2004-08-01

Frontal fibrosing alopecia (FFA) is an uncommon, slowly progressive, cicatricial alopecia which mainly affects postmenopausal women. It is considered to be a variant of lichen planopilaris. We describe two postmenopausal women who developed over 11 and 24 months an asymptomatic atrophic alopecia, restricted to the frontal hairline. The diagnosis of FFA was confirmed by biopsy showing a perifollicular lymphocytic infiltrate with fibrosis. Topical corticosteroids, in one case combined with minoxidil, administered for 3 months arrested the hair loss. The treatment of FFA is often difficult. In most cases, the disease resolves spontaneously after several years. Immunomodulators such as corticosteroids and calcineurin antagonists should be tried in the early stage of FFA (frontal effluvium with perifollicular erythema) in order to arrest the disease in its inflammatory phase.

Various trials have been conducted on the management and treatment of androgenic alopecia (AGA) or male pattern hair loss using a variety of laser and light sources. For this feasibility study, the population was composed of males between the ages of 20 and 60 years who have been experiencing active hair loss within the last 12 months and the diagnosis of AGA. They also had a Norwood-Hamilton classification of 3, 3A, 3 V, 4, 4A, or 5 for the hair thinning patterns and skin type I, II, III, or IV on the Fitzpatrick skin type scale. This two-arm randomized, parallel group study design employed stratifying randomization to balance treatment assignment within three investigational centers with at least 2 subjects enrolled in each Fitzpatrick skin type. A statistically significant positive trend in hair growth was observed from this pilot study, to evaluate the efficacy of the novel cold X5 hairlaser device for treating male androgenic alopecia. From the repeated measures analysis of variance, difference in mean hair counts over time was statistically significant (F = 7.70; p-value < 0.0001). Subsequent, linear regression of mean hair counts at each time point was performed, and post-hoc analysis found an increasing trend of hair growth over time that was statistically significant (p-value < 0.0001) with the estimated slope of 1.406. Increased hair counts from the baseline to the end of the 26-week period were found to be strongly significant (p-value = 0.0003). Albeit, sham device failure and resultant missing data from the control group, the positive trend hair growth, was observed due to the chronic use of X5hairlaser device. This positive benefit while in full agreement with other low laser hair devices requires intensive further investigation. NCT02067260.

Acne keloidalis nuchae: prevalence, impact, and management challenges

Ogunbiyi, Adebola

2016-01-01

Acne keloidalis nuchae (AKN) also known as folliculitis keloidalis nuchae (FKN) is a chronic form of scarring folliculitis seen mostly in men of African descent. The term AKN is commonly used even though the condition is not a keloid, and the affected individuals do not have a tendency to develop keloids in other areas of the body. It is seen in post pubertal men and is rare after the age of 55 years. A few cases have been reported in females. which has been classified as a primary cicatricial alopecia since the exact cause of acne keloidalis (AK) remains unknown. However, a few inciting agents have been suggested which include androgens, inflammation, infection, trauma, genetics, and ingrowing hairs. AK shares some similar features with other forms of cicatricial alopecia and may occur together. Papules, pustules, and sometimes tumorous masses in the nuchal or occipital regions of the scalp hence the name “bumps” evolved in the environment. Despite its common occurrence, only a few seek help in hospital when lesions start to unsightly affect the individual’s quality of life. The presences of the keloidal lesions are more stressful compared to the resulting alopecia. Various attempts to reduce the bumps with corrosives, acids, and car engine oils lead to larger lesions or unsightly scars. Active lesions produce bleeding during haircuts. This is worrisome as a couple of individuals with active AK share shaving instruments at the barber shop and are at risk of acquiring or transmitting blood-borne infections. There is an urgent need to encourage safe shaving habits and treatment of lesions at onset so as to prevent unsightly lesions. PMID:28008278

Chemotherapy-induced alopecia (CIA) is one of the most distressing side effects of antineoplastic chemotherapy for which there is no effective interventional approach. A low-level laser (LLL) device, the HairMax LaserComb®, has been cleared by the FDA to treat androgenetic alopecia. Its effects may be extended to other settings; we have demonstrated that LaserComb treatment induced hair regrowth in a mouse model for alopecia areata. In the current study, we tested whether LLL treatment could promote hair regrowth in a rat model for CIA. Chemotherapy agents cyclophosphamide, etoposide, or a combination of cyclophosphamide and doxorubicin were administered in young rats to induce alopecia, with or without LLL treatment. As expected, 7-10 days later, all the rats developed full body alopecia. However, rats receiving laser treatment regrew hair 5 days earlier than rats receiving chemotherapy alone or sham laser treatment (with the laser turned off). The accelerated hair regrowth in laser-treated rats was confirmed by histology. In addition, LLL treatment did not provide local protection to subcutaneously injected Shay chloroleukemic cells. Taken together, our results demonstrated that LLL treatment significantly accelerated hair regrowth after CIA without compromising the efficacy of chemotherapy in our rat model. Our results suggest that LLL should be explored for the treatment of CIA in clinical trials because LLL devices for home use (such as the HairMax LaserComb®) provide a user-friendly and noninvasive approach that could be translated to increased patient compliance and improved efficacy.

Hair loss in women.

PubMed

Camacho-Martínez, Francisco M

2009-03-01

Female pattern hair loss (FPHL) is a clinical problem that is becoming more common in women. Female alopecia with androgen increase is called female androgenetic alopecia (FAGA) and without androgen increase is called female pattern hair loss. The clinical picture of typical FAGA begins with a specific "diffuse loss of hair from the parietal or frontovertical areas with an intact frontal hairline." Ludwig called this process "rarefaction." In Ludwig's classification of hair loss in women, progressive type of FAGA, 3 patterns were described: grade I or minimal, grade II or moderate, and grade III or severe. Ludwig also described female androgenetic alopecia with male pattern (FAGA.M) that should be subclassified according to Ebling's or Hamilton-Norwood's classification. FAGA.M may be present in 4 conditions: persistent adrenarche syndrome, alopecia caused by an adrenal or an ovarian tumor, posthysterectomy, and as an involutive alopecia. A more recent classification (Olsen's classification of FPHL) proposes 2 types: early- and late-onset with or without excess of androgens in each. The diagnosis of FPHL is made by clinical history, clinical examination, wash test, dermoscopy, trichoscan, trichograms and laboratory test, especially androgenic determinations. Topical treatment of FPHL is with minoxidil, 2-5% twice daily. When FPHL is associated with high levels of androgens, systemic antiandrogenic therapy is needed. Persistent adrenarche syndrome (adrenal SAHA) and alopecia of adrenal hyperandrogenism is treated with adrenal suppression and antiandrogens. Adrenal suppression is achieved with glucocorticosteroids. Antiandrogens therapy includes cyproterone acetate, drospirenone, spironolactone, flutamide, and finasteride. Excess release of ovarian androgens (ovarian SAHA) and alopecia of ovarian hyperandrogenism is treated with ovarian suppression and antiandrogens. Ovarian suppression includes the use of contraceptives containing an estrogen, ethinylestradiol, and a progestogen. Antiandrogens such as cyproterone acetate, always accompanied by tricyclic contraceptives, are the best choice of antiandrogens to use in patients with FPHL. Gonadotropin-releasing hormone agonists such as leuprolide acetate suppress pituitary and gonadal function through a reduction in luteinizing hormone and follicle-stimulating hormone levels. Subsequently, ovarian steroid levels also will be reduced, especially in patients with polycystic ovary syndrome. When polycystic ovary syndrome is associated with insulin resistance, metformin must be considered as treatment. Hyperprolactinemic SAHA and alopecia of pituitary hyperandrogenism should be treated with bromocriptine or cabergoline. Postmenopausal alopecia, with previous high levels of androgens or with prostatic-specific antigen greater than 0.04 ng/mL, improves with finasteride or dutasteride. Although we do not know the reason, postmenopausal alopecia in normoandrogenic women also improves with finasteride or dutasteride at a dose of 2.5 mg per day. Dermatocosmetic concealment with a hairpiece, hair prosthesis as extensions, or partial hairpieces can be useful. Lastly, weight loss undoubtedly improves hair loss in hyperandrogenic women.

Androgenic alopecia may have evolved to protect men from prostate cancer by increasing skin exposure to ultraviolet radiation.

PubMed

Kabai, Peter

2008-01-01

Androgenic alopecia affects populations adapted to colder climate, and individuals at an age and hormonal status susceptible to prostate cancer. Male pattern baldness enhances absorption of UV radiation on the top of the head, an area directly exposed to sunlight during everyday activities. Ultraviolet radiation is reported to reduce the risk of advanced prostate cancer. Here I propose that progression of androgenic alopecia rather than being a risk factor is a finely tuned mechanism evolved to protect against prostate cancer.

Alopecia is a common disorder affecting more than half of the population worldwide. Androgenetic alopecia, the most common type, affects 50% of males over the age of 40 and 75% of females over 65. Only two drugs have been approved so far (minoxidil and finasteride) and hair transplant is the other treatment alternative. This review surveys the evidence for low-level laser therapy (LLLT) applied to the scalp as a treatment for hair loss and discusses possible mechanisms of actions. Searches of PubMed and Google Scholar were carried out using keywords alopecia, hair loss, LLLT, photobiomodulation. Studies have shown that LLLT stimulated hair growth in mice subjected to chemotherapy-induced alopecia and also in alopecia areata. Controlled clinical trials demonstrated that LLLT stimulated hair growth in both men and women. Among various mechanisms, the main mechanism is hypothesized to be stimulation of epidermal stem cells in the hair follicle bulge and shifting the follicles into anagen phase. LLLT for hair growth in both men and women appears to be both safe and effective. The optimum wavelength, coherence and dosimetric parameters remain to be determined. © 2013 Wiley Periodicals, Inc.

This study aims to evaluate the impact of chemotherapy-induced alopecia (CIA) distress on body image, psychosocial well-being, and depression among breast cancer patients. A cross-sectional survey was conducted at the breast cancer advocacy events held at 16 hospitals in Korea. Alopecia distress was assessed using the 'Chemotherapy-Induced Alopecia Distress Scale', body image and psychosocial well-being were measured by the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 and breast specific module (BR23), and depression was measured using the Center for Epidemiological Studies Depression scale. Means of outcomes were compared between low and high CIA distress groups. Univariable and multivariable linear regression models were used to analyze the relationship between the CIA distress and body image, psychosocial well-being, and depression. One hundred sixty-eight breast cancer patients participated in the study; the mean age was 48.4 (SD = 8.4) years, and 55.3% of the patients experienced higher distress from alopecia. In fully adjusted models, the high distress group was more likely to have a poorer body image than the low distress group (35.2 vs. 62.0; p < 0.001). Distressed patients were also more likely to report lower emotional (55.3 vs. 76.9; p < 0.001), role (58.6 vs. 72.0; p < 0.001), and social functioning (51.3 vs. 70.9; p < 0.001). The high distress group was also more likely to have depression compared with the low distress group (19.6 vs. 14.8; p < 0.001). Chemotherapy-induced alopecia distress was negatively associated with body image, psychosocial well-being, and depression in women with breast cancer. It is necessary to develop specific interventions to minimize distress due to alopecia for women with breast cancer. Copyright © 2014 John Wiley & Sons, Ltd.

Alopecia X is a hair cycle arrest disorder in Pomeranians. Histologically, kenogen and telogen hair follicles predominate, whereas anagen follicles are sparse. The induction of anagen relies on the activation of hair follicle stem cells and their subsequent proliferation and differentiation. Stem cell function depends on finely tuned interactions of signaling molecules and transcription factors, which are not well defined in dogs. We performed transcriptome profiling on skin biopsies to analyze altered molecular pathways in alopecia X. Biopsies from five affected and four non-affected Pomeranians were investigated. Differential gene expression revealed a downregulation of key regulator genes of the Wnt (CTNNB1, LEF1, TCF3, WNT10B) and Shh (SHH, GLI1, SMO, PTCH2) pathways. In mice it has been shown that Wnt and Shh signaling results in stem cell activation and differentiation Thus our findings are in line with the lack of anagen hair follicles in dogs with Alopecia X. We also observed a significant downregulation of the stem cell markers SOX9, LHX2, LGR5, TCF7L1 and GLI1 whereas NFATc1, a quiescence marker, was upregulated in alopecia X. Moreover, genes coding for enzymes directly involved in the sex hormone metabolism (CYP1A1, CYP1B1, HSD17B14) were differentially regulated in alopecia X. These findings are in agreement with the so far proposed but not yet proven deregulation of the sex hormone metabolism in this disease.

Deslorelin Implant Treatment for Hair Cycle Arrest (Alopecia X) in Two Intact Male Keeshonden.

PubMed

Layne, Elizabeth A; Richmond, Renee V

Alopecia in dogs occurs secondary to a variety of underlying inflammatory and noninflammatory conditions. Hair cycle arrest (alopecia X) is a noninflammatory alopecia that is frustrating to diagnose and treat due to lack of understanding of disease pathogenesis. A variety of therapies for hair cycle arrest have been described with inconsistent efficacy in different dog breeds and sexes; no definitive treatment is available. This report describes the use of a deslorelin acetate implant in two sexually intact adult male keeshonden, both diagnosed with hair cycle arrest. The dogs had progressive alopecia of the trunk that spared the head and distal limbs present for at least 2 yr. Diagnosis of hair cycle arrest was made based on clinical features, dermatohistopathology, and lack of systemic abnormalities. Treatment with a single subcutaneous 4.7 mg deslorelin acetate implant resulted in profuse hair regrowth within 3.5 mo that endured for at least 14 mo. Deslorelin implantation is a management option that is safe, affordable, and appears effective for sexually intact male keeshonden with hair cycle arrest.

Noninflammatory alopecia is a frequent problem in dogs, and the pathogenesis is still unclear. The objective of this study was a comparative histological description of skin biopsies from dogs with different alopecic disorders and control dogs matched for coat type, season and disease duration. Twenty-one cases of alopecia X in plush-coated dogs, 12 cases of recurrent flank alopecia, three cases of hyperestrogenism, 15 cases of hyperadrenocorticism, 12 cases of hypothyroidism and 12 cases of primary alopecic disorders of unknown cause were evaluated. The controls were biopsies from 38 dogs of different coat types. We evaluated five serial sections of each biopsy histologically and immunohistologically to compare the histological findings within the disease groups and with the control. All the dogs with hair cycle disorders had a significant increase in the number of hairless hair follicles, which we assigned to kenogen. In addition, dogs with alopecia X had the lowest percentage of anagen follicles and the highest percentage of telogen follicles. The marked increase in kenogen follicles is a strong indication that the induction of the new anagen phase is impaired in hair cycle disorders. The findings in dogs with alopecia X further suggest that premature catagen is also involved in the pathogenesis. Further work to investigate the stem cell compartment and possible initiating factors for the different cycle phases is required to elucidate the exact pathogenesis. © 2012 The Authors.

The case notes of 7 consecutive patients treated with Augmentin Duo 400/57 for BKC during 18 months were reviewed. Diagnostic criteria for BKC were blepharitis including recurrent chalazia and meibomian gland dysfunction, eyelid margin telangiectasia and facial rosacea, recurrent episodes of chronic red eye, photophobia, watering, punctate superficial keratopathy, corneal neovascularization, and corneal ulcers. Seven children (age range: 6 to 14 years) were diagnosed as having BKC. All children received systemic Augmentin Duo 400/57 and showed considerable improvement within the first month of therapy. Six children had no recurrences during a mean follow-up of 6 months. No patients experienced any side effects from this treatment. Augmentin Duo 400/57 has not previously been reported in the treatment of BKC in children. In this case series, Augmentin Duo 400/57 proved to be at least as effective as current treatments with systemic erythromycin or doxycycline with the advantage of a twice-daily dosage and a superior side-effect profile.

Alopecia areata is a form of non-scarring alopecia that results from a hyperactive immune response of T cells against hair follicles. Many patients with visible hair loss experience psychological and emotional distress, as a result of their cosmetic disfigurement, and frequently seek treatment. However, existing treatment methods, such as corticosteroids, topical irritants, sensitizing agents, immunosuppressants, and psoralen plus ultraviolet light A, may result in various adverse effects and often lack efficacy. Laser and light treatments offer a safe and effective alternative. This review aims to provide clinicians with a comprehensive summary of laser and light-based modalities used for the treatment of alopecia areata. Currently, the excimer laser is the most widely studied device and has shown positive results thus far. However, the development of future randomized controlled clinical trials will help determine the appropriate treatment protocols necessary, in order to achieve superior clinical outcomes.

Case reports: alopecia universalis: hair growth following initiation of simvastatin and ezetimibe therapy.

Robins, Douglas N

Alopecia areata is an organ specific autoimmune disease in which hair is lost in various patterns. Its most extreme form, alopecia universalis, is the total loss of all scalp and body hair. This form of the condition is very resistant to treatment and spontaneous remission is quite rare. The following is a case of a 54-year-old male with longstanding alopecia universalis who began to grow dense hair on his scalp as well as patchy hair growth on his face, pubic and axillary areas one month after starting a course of simvastatin 40 mg and ezetimibe 10 mg daily prescribed for his hyperlipidemia. For 2 years prior to starting the combination drug, he had taken simvastatin 40 mg alone without evidence of any hair growth. The combination of simvastatin and ezetimibe has previously demonstrated synergistic immunomodulatory effects, which most likely accounts for the clinical response in this case.

Both ablative and non-ablative fractional lasers have been applied to various uncommon hair disorders. The purpose of this study was to demonstrate the clinical effects of fractional laser therapy on the course of primary follicular and perifollicular pathologies and subsequent hair regrowth. A retrospective review of 17 patients with uncommon hair disorders - including ophiasis, autosomal recessive woolly hair/hypotrichosis, various secondary cicatricial alopecias, pubic hypotrichosis, frontal fibrosing alopecia, and perifolliculitis abscedens et suffodiens - was conducted. All patients had been treated with non-ablative and/or ablative fractional laser therapies. The mean clinical improvement score in these 17 patients was 2.2, while the mean patient satisfaction score was 2.5. Of the 17 subjects, 12 (70.6%) demonstrated a clinical response to non-ablative and/or ablative fractional laser treatments, including individuals with ophiasis, autosomal recessive woolly hair/hypotrichosis, secondary cicatricial alopecia (scleroderma and pressure-induced alopecia), frontal fibrosing alopecia, and perifolliculitis abscedens et suffodiens. Conversely, patients with long-standing ophiasis, surgical scar-induced secondary cicatricial alopecia, and pubic hypotrichosis did not respond to fractional laser therapy. Our findings demonstrate that the use of non-ablative and/or ablative fractional lasers promoted hair growth in certain cases of uncommon hair disorders without any remarkable side effects.

Alopecia (hair loss) has been observed in several marine mammal species and has potential energetic consequences for sustaining a normal core body temperature, especially for Arctic marine mammals routinely exposed to harsh environmental conditions. Polar bears (Ursus maritimus) rely on a thick layer of adipose tissue and a dense pelage to ameliorate convective heat loss while moving between sea ice and open water. From 1998 to 2012, we observed an alopecia syndrome in polar bears from the southern Beaufort Sea of Alaska that presented as bilaterally asymmetrical loss of guard hairs and thinning of the undercoat around the head, neck, and shoulders, which, in severe cases, was accompanied by exudation and crusted skin lesions. Alopecia was observed in 49 (3.45%) of the bears sampled during 1,421 captures, and the apparent prevalence varied by years with peaks occurring in 1999 (16%) and 2012 (28%). The probability that a bear had alopecia was greatest for subadults and for bears captured in the Prudhoe Bay region, and alopecic individuals had a lower body condition score than unaffected individuals. The cause of the syndrome remains unknown and future work should focus on identifying the causative agent and potential effects on population vital rates.

Alopecia areata is an autoimmune inflammatory disease affecting the hair follicles. Researchers are currently interested in whether the presence of bacterial pathogens and/or a history of immunization can trigger an autoimmune response in patients who are genetically predisposed. This study aimed to determine whether there is an association between the development of alopecia areata and throat carriage of bacterial pathogens or a history of immunization. Sixty-five men and women with alopecia areata and 65 control patients with other skin diseases were studied at the Dr Ladislao de la Pascua Dermatology Clinic between September 2008 and February 2009. The patients ranged in age from 18-59 years. Patients with scalp diseases were excluded from the control group. In all cases, the patient was questioned about immunizations received in the previous 6 months, and a throat swab was cultured. A history of immunization (odds ratio [OR], 3.3; 95% confidence interval [CI], 1.6-6.7; P=.001), the presence of bacterial pathogens in the oropharynx (OR, 2.6; 95% CI, 1.1-6.2; P=.033), and being a carrier of Streptococcus pyogenes (OR, 2.1; 95% CI, 1.7-2.5; P=.042) were risk factors for alopecia areata. Klebsiella pneumoniae, S. pyogenes, Pseudomonas aeruginosa, Streptococcus pneumoniae, Serratia marcescens and Escherichia coli were isolated from cultures. This is the first study to show an association between alopecia areata and throat carriage of bacterial pathogens or history of immunization, as risk factors for development of the disease. Given the characteristics of our study population, the association appears valid for patients with less than 25% hair loss and a course of disease under 1 year.

Localized demodicosis due to Demodex cati on the muzzle of two cats treated with inhalant glucocorticoids.

2014-06-01

Feline demodicosis due to Demodex cati is a rare skin disease often associated with concurrent disease and generalized immunosuppression. Local immunosuppression due to the application of topical immunomodulatory drugs, such as glucocorticoids and tacrolimus, or by tumour cells has been suggested as a potential trigger for development of localized demodicosis in humans and animals. The goal was to describe two cats with asthma that developed localized demodicosis on the muzzle as a result of chronic therapy with a glucocorticoid administered via dispensing inhaler mask. In both cats, the muzzle area exposed to the fluticasone-dispensing chamber exhibited patchy alopecia, mild erythema, crusting and scaling. Deep skin scraping revealed D. cati. Discontinuation or reduction of fluticasone and administration of milbemycin resulted in resolution of clinical signs within 2 months in both cats. A negative skin scrape was obtained after 7 months of milbemycin in one of the cats. Demodicosis should be considered as a possible differential diagnosis in cats with primary alopecia or other skin lesions on the face exposed to inhalant glucocorticoids. Minimization of contact between the inhalant glucocorticoid and the skin can be achieved by wiping residual powder from the face and by keeping the mask tightly pressed to the skin to avoid contact with the surrounding area. © 2014 ESVD and ACVD.

Female androgenetic alopecia or female-pattern alopecia is one of the most common causes of hair loss, affecting 50 % of women over their lifetime. The appearance of this condition is the cause of significant stress and psychological problems, making appropriate management important. Cases exist in which it is associated with hyperandrogenism. Here, we review the different clinical forms (diffuse, male-pattern, and Christmas-tree pattern), discuss the most appropriate laboratory tests (complete blood count, thyroid stimulating hormone, ferritin, prolactin, free and/or total testosterone, and dehydroepiandrosterone sulfate), and the different treatments, including finasteride.

The aim of the study was to evaluate efficacy and safety of 5% Carexidil solution®, applied twice a day on the scalp, on male and female androgenetic alopecia. The 6 month-study was performed in three Italian dermatological centers. Evaluation of efficacy was performed with subjective and objective methods, including operator and patient assessments, global photography and videodermoscopy. Global photography revealed that after 6 months of treatment with 5% Carexidil solution®, androgenetic alopecia was improved in all 32 females and 16 males. Alopecia stopped to progress in 6 males. Scalp videodermoscopy confirmed the results. Some patients complained of increased hair greasiness, others complained of mild scalp itching. Two female patients developed contact sensitization to minoxidil, confirmed by patch test, 2 a mild malar-temporal hypertrichosis. All patients were satisfied by treatment and continued it after the end of the study. Our study confirms the data of the literature and the evidence coming from years of clinical experience, that twice a day topical application of 5% minoxidil solution, Carexidil ®, is effective in the treatment of male and female androgenetic alopecia, with evident efficacy already after 6 months.

Chemotherapy-induced alopecia is a well-established cause of major distress to patients. Permanent chemotherapy-induced alopecia (PCIA) is the absence of or incomplete hair regrowth lasting longer than 6 months after the cessation of chemotherapy and it does not respond to standard treatments of scalp cooling or topical minoxidil. The increasing numbers of reports of PCIA highlight the need for research into an effective treatment.

A 9-yr-old male cheetah (Acinonyx jubatus) housed at the Cheetah Conservation Fund in Namibia developed cutaneous lesions consisting of alopecia, erythema, ulceration, and crusting on the left fore and hind limbs. Histopathology of skin biopsies in conjunction with indirect fluorescent antibody and polymerase chain reaction testing confirmed a diagnosis of feline herpesvirus-1 dermatitis; microbial culture indicated secondary bacterial infection. Therapy included targeted systemic antimicrobial and antiviral treatment, topical medications, and repeated cryotherapy. Lesions exhibited varying degrees of clinical improvement but, overall, progressed in extent, size, and severity during the subsequent 2.5 yr of intense treatment. The cheetah was ultimately euthanized due to a guarded prognosis and concerns about poor quality of life. Potential factors initiating or contributing (or both) to the severity and nonhealing nature of the cutaneous lesions include chronic unidentified stress, altered immune system function, and other environmental influences.

Inflammatory bowel disease (IBD) is a chronic disease of the gastrointestinal tract attributed to aberrant activity of the immune system. Increasing evidence suggests that patients with IBD are at an increased risk of inflammatory skin diseases (ISDs). We sought to clarify the association between IBD and ISDs using a nationwide health claims database maintained in Korea. We interrogated Korean health claim database data from 2009 to 2013. We enrolled all patients with IBD, and age- and sex-matched control subjects, and evaluated the risks of ISDs, including psoriasis, rosacea, and atopic dermatitis, and the risks of autoimmune skin diseases, including vitiligo and alopecia areata. We used multivariable logistic regression to this end. ISDs including rosacea, psoriasis, and atopic dermatitis were significantly associated with IBD, whereas the associations between IBD and autoimmune skin diseases including vitiligo and alopecia areata were less marked or nonexistent. Ulcerative colitis and Crohn's disease were both associated with ISDs. We were unable to distinguish phenotypes and severities of skin diseases. IBD was significantly associated with ISDs, but less so or not at all with autoimmune skin diseases. Copyright © 2016 American Academy of Dermatology, Inc. Published by Elsevier Inc.

There are many new low-level laser technologies that have been released commercially that claim to support hair regrowth. In this paper, we will examine the clinical trials to determine whether the body of evidence supports the use of low-level laser therapy (LLLT) to treat androgenic alopecia (AGA). A literature search was conducted through Pubmed, Embase, and Clinicaltrials.gov for clinical trials using LLLT to treat AGA. Thirteen clinical trials were assessed. Review articles were not included. Ten of 11 trials demonstrated significant improvement of androgenic alopecia in comparison to baseline or controls when treated with LLLT. In the remaining study, improvement in hair counts and hair diameter was recorded, but did not reach statistical significance. Two trials did not include statistical analysis, but showed marked improvement by hair count or by photographic evidence. Two trials showed efficacy for LLLT in combination with topical minoxidil. One trial showed efficacy when accompanying finasteride treatment. LLLT appears to be a safe, alternative treatment for patients with androgenic alopecia. Clinical trials have indicated efficacy for androgenic alopecia in both men and women. It may be used independently or as an adjuvant of minoxidil or finasteride. More research needs to be undertaken to determine the optimal power and wavelength to use in LLLT as well as LLLT's mechanism of action.

Development of optical biopsy methods has a great interest for medical diagnostics. In clinical and experimental studies it is very important to analyze blood circulation quickly and accurately, thereby laser Doppler flowmetry (LDF) is widely used. UV laser-induced fluorescence spectroscopy (UV LIFS) is express highly sensitive and widely-spread method with no destructive impact, high excitation selectivity and the possibility to use in highly scattering media. The goal of this work was to assess a correlation of UV laser-induced fluorescence spectroscopy and laser Doppler flowmetry parameters, and a possibility to identify or to differentiate various types of pathological changes in tissues according to their autofluorescence spectra. Three groups of patients with diffuse (symptomatic) alopecia, androgenic alopecia, and focal alopecia have been tested. Each groups consisted of not less than 20 persons. The measurements have been done in the parietal and occipital regions of the sculls. We used the original automated spectrofluorimeter to record autofluorescence spectra, and standard laser Doppler flowmeter BLF-21 (Transonic Systems, Inc., USA) to analyze the basal levels of blood circulation. Our results show that UV LIFS accurately distinguishes the zones with different types of alopecia. We found high correlation of the basal levels of blood circulation and the integrated intensity of autofluorescence in the affected tissue.

The protective role of the immunomodulator AS101 against chemotherapy-induced alopecia studies on human and animal models.

The immunomodulator AS101 has been demonstrated to exhibit radioprotective and chemoprotective effects in mice. Following phase-I studies, preliminary results from phase-II clinical trials on non-small-cell-lung-cancer patients showed a reduction in the severity of alopecia in patients treated with AS101 in combination with chemotherapy. To further substantiate these findings, the present study was extended to include 58 patients treated either with the optimal dose of 3 mg/m2 AS101 combined with carboplatin and VP-16, or with chemotherapy alone. As compared with patients treated with chemotherapy alone, there was a significant decrease in the level of alopecia in patients receiving the combined therapy. The newly developed rat model was used to elucidate the protective mechanism involved in this effect. We show that significant prevention of chemotherapy-induced alopecia is obtained in rats treated with Ara-C combined with AS101, administered i.p. or s.c. or applied topically to the dorsal skin. We show that this protection by AS101 is mediated by macrophage-derived factors induced by AS101. Protection by AS101 can be ascribed, at least in part, to IL-1, since treatment of rats with IL-1 RA largely abrogated the protective effect of AS101. Moreover, we demonstrate that in humans there is an inverse correlation between the grade of alopecia and the increase in IL-1 alpha. In addition, protection by AS101 could be related to PGE2 secretion, since injection of indomethacin before treatment with AS101 and Ara-C partly abrogated the protective effect of AS101. To assess the ability of AS101 to protect against chemotherapy-induced alopecia, phase-II clinical trials have been initiated with cancer patients suffering from various malignancies.

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. Diagnosis and follow up were done by serial digital camera photography of lesions and dermoscopic scan before and every 1 month after treatment for 3 months. Patients treated with minoxidil 5% and platelets rich plasma both have significant hair growth than placebo (p < .05). Patients treated with platelets rich plasma had an earlier response in the form of hair regrowth, reduction in short vellus hair and dystrophic hair unlike patients treated with minoxidil and control (p < .05). In conclusion, platelets rich plasma is more effective in the treatment of alopecia areata than topical minoxidil 5% as evaluated by clinical and trichoscopic examination. © 2016 Wiley Periodicals, Inc.

For nearly two decades, dermatology has associated with psychology to find a better way to care for dermatology conditions. A scientific trend called psychosomatics is creating a link between dermatology and psychology. The purpose of this article was to examine two concepts closely linked to psychodermatology (life events and tendency to complain) and to emphasize the difference between factors playing a role in the onset of certain skin diseases (psoriasis, alopecia areata, benign tumors, eczema). We found that psoriasis patients have a greater tendency to complain than people with the other disease. This point to the importance of taking emotions into account when studying psoriasis. We also found that life events play a role in the onset of psoriasis and alopecia areata. Moreover, these events were anterior by more than 12 months in alopecia patients. We propose exploring emotions in psoriasis patients and life events over the prior year in alopecia areata patients.

Alopecia with mental retardation (APMR) is a very rare disorder. In this study, we report on a consanguineous Pakistani family (AP91) with mild-to-moderate intellectual disability, adolescent alopecia and dentogingival abnormalities. Using homozygosity mapping, linkage analysis and exome sequencing, we identified a novel rare missense variant c.898G>A (p.(Glu300Lys)) in ITGB6, which co-segregates with the phenotype within the family and is predicted to be deleterious. Structural modeling shows that Glu300 lies in the β-propeller domain, and is surrounded by several residues that are important for heterodimerization with α integrin. Previous studies showed that ITGB6 variants can cause amelogenesis imperfecta in humans, but patients from family AP91 who are homozygous for the c.898G>A variant present with neurological and dermatological features, indicating a role for ITGB6 beyond enamel formation. Our study demonstrates that a rare deleterious variant within ITGB6 causes not only dentogingival anomalies but also intellectual disability and alopecia.

Androgenetic alopecia is the most common form of hair loss. Minoxidil has been approved for the treatment of hair loss, however its mechanism of action is still not fully clarified. In this study, we aimed to elucidate the effects of 5% minoxidil topical foam on gene expression and activation of signaling pathways in vertex and frontal scalp of men with androgenetic alopecia. We identified regional variations in gene expression and perturbed signaling pathways using in silico Pathway Activation Network Decomposition Analysis (iPANDA) before and after treatment with minoxidil. Vertex and frontal scalp of patients showed a generally similar response to minoxidil. Both scalp regions showed upregulation of genes that encode keratin associated proteins and downregulation of ILK, Akt, and MAPK signaling pathways after minoxidil treatment. Our results provide new insights into the mechanism of action of minoxidil topical foam in men with androgenetic alopecia.

Can you pull it off? Appearance modifying behaviours adopted by wig users with alopecia in social interactions.

2014-03-01

In the academic and medical literature on alopecia, wigs (hair prostheses) are typically recommended as a coping strategy: a device to camouflage, conceal, or cover hair loss, and cope with the psychological impact of a dramatic change in body image. This paper used Goffman's (1959) theory of impression management to demonstrate (a) the social significance of self-presentation, and (b) how adults with alopecia managed their wig use in their daily lives. Data from 14 interviews, two focus groups and six video diaries with 22 Caucasian adults (19 females, 3 males; 29-74 years, SD=13.75) with alopecia in Scotland were analysed using discursive psychology. The analysis detailed how participants managed their wig use and behaviours in relation to social interaction with different categories of people. The paper raises concerns about health and medical discourse about wigs as a coping mechanism, and provides practical suggestions for wig users in social settings. Copyright © 2014 Elsevier Ltd.

Ocular tick infestation can occur in any age group or sex with exposure in an endemic setting. All parts of the ocular tissue have been reported to be susceptible to tick infestation. The authors present a rare patient with tick infestation of eyelid.An 88-year-old woman was referred for a yellowish lesion of the right upper eyelid. She had a history of sting 2 days before presentation, and developed eyelid swelling with mucopurulent discharge the next day. Slit lamp examination showed blepharitis and revealed that the lesion was the body of a hard tick, firmly attached to eyelid. First, blunt forceps were used for removal of the tick under a surgical microscope. However, attempted removal resulted in the disembodiement of the parasite and retention of the mouthparts in the skin. The retained tick parts were excised en bloc by skin punch biopsy. The tick was identified as Ixodes nipponensis. Subsequent treatment was given for blepharitis and skin lesion.This case introduces a rare patient with tick infestation of eyelid, and the proper management. Less than 20 documented patients with tick infestation of eyelid have been reported worldwide, and this is the first patient from South Korea in ophthalmological society.

The authors tried to verify the efficacy of low energy laser (LEL) in scalp alopecia. Sixty patients were divided in two groups: A) laser group, 33 patients treated with both LEL and classical therapy; B) control group, 27 patients treated only with classical therapy, Before, during and after treatment, historical samples were done. For the group A the results were rather superior but in a twice shorter time shorter time than group B. The maintenance of the good results needed classical therapy for a long period. We conclude that LEL therapy could have a useful complementary method for the treatment of scalp alopecia.

2014-01-01

Background Various trials have been conducted on the management and treatment of androgenic alopecia (AGA) or male pattern hair loss using a variety of laser and light sources. Methods For this feasibility study, the population was composed of males between the ages of 20 and 60 years who have been experiencing active hair loss within the last 12 months and the diagnosis of AGA. They also had a Norwood-Hamilton classification of 3, 3A, 3 V, 4, 4A, or 5 for the hair thinning patterns and skin type I, II, III, or IV on the Fitzpatrick skin type scale. This two-arm randomized, parallel group study design employed stratifying randomization to balance treatment assignment within three investigational centers with at least 2 subjects enrolled in each Fitzpatrick skin type. Results A statistically significant positive trend in hair growth was observed from this pilot study, to evaluate the efficacy of the novel cold X5 hairlaser device for treating male androgenic alopecia. From the repeated measures analysis of variance, difference in mean hair counts over time was statistically significant (F = 7.70; p-value < 0.0001). Subsequent, linear regression of mean hair counts at each time point was performed, and post-hoc analysis found an increasing trend of hair growth over time that was statistically significant (p-value < 0.0001) with the estimated slope of 1.406. Increased hair counts from the baseline to the end of the 26-week period were found to be strongly significant (p-value = 0.0003). Conclusion Albeit, sham device failure and resultant missing data from the control group, the positive trend hair growth, was observed due to the chronic use of X5hairlaser device. This positive benefit while in full agreement with other low laser hair devices requires intensive further investigation. Trial registration NCT02067260 PMID:24559020

The effectiveness of treatments for androgenetic alopecia: A systematic review and meta-analysis.

PubMed

Adil, Areej; Godwin, Marshall

Androgenetic alopecia, or male pattern hair loss, is a hair loss disorder mediated by dihydrotestosterone, the potent form of testosterone. Currently, minoxidil and finasteride are Food and Drug Administration (FDA)-approved, and HairMax LaserComb, which is FDA-cleared, are the only treatments recognized by the FDA as treatments of androgenetic alopecia. This systematic review and meta-analysis assesses the efficacy of nonsurgical treatments of androgenetic alopecia in comparison to placebo for improving hair density, thickness, growth (defined by an increased anagen:telogen ratio), or subjective global assessments done by patients and investigators. A systematic review of randomized controlled trials was conducted. PubMed, Embase, and Cochrane were searched up to December 2016, with no lower limit on the year. We included only randomized controlled trials of good or fair quality based on the US Preventive Services Task Force quality assessment process. A meta-analysis was conducted separately for 5 groups of studies that tested the following hair loss treatments: low-level laser light therapy in men, 5% minoxidil in men, 2% minoxidil in men, 1 mg finasteride in men, and 2% minoxidil in women. All treatments were superior to placebo (P < .00001) in the 5 meta-analyses. Other treatments were not included because the appropriate data were lacking. High heterogeneity in most studies. This meta-analysis strongly suggests that minoxidil, finasteride, and low-level laser light therapy are effective for promoting hair growth in men with androgenetic alopecia and that minoxidil is effective in women with androgenetic alopecia.

Eleven patients with alopecia areata affecting 10% to 75% of the scalp, average duration 6 years, had no terminal hair growth in response to tacrolimus ointment 0.1% applied twice daily for 24 weeks. Treatment failure may reflect insufficient depth of penetration of the ointment formulation and less than optimal patient selection.

In frontal fibrosing alopecia (FFA), scalp alopecia dominates the clinical picture. However, eyebrow loss and hair loss in other body sites may also occur; this has been documented clinically, but rarely histopathologically. We describe the clinicopathological findings of 13 cases of FFA, with histopathologic data from the scalp, eyebrow, and body hair. Thirteen patients with a diagnosis of FFA, seen between 2006 and 2008, were included. Scalp biopsies were performed in all patients for histology and direct immunofluorescence (DIF). Biopsy specimens for histology were taken from the eyebrow in 6 patients and from the upper limb in 5 patients. All 13 patients were female, 11 of whom were postmenopausal. The median age at onset of alopecia was 57 years. Clinical examination revealed a band of frontal hairline recession in all patients. Eyebrow loss was present clinically in all patients, with loss of body hair in 10 of 13. Histopathologic examination of the scalp, eyebrow, and upper limb skin biopsy specimens showed similar features, including a marked reduction in the number of hair follicles and a perifollicular lymphoid cell infiltrate with perifollicular fibrosis. Direct immunofluorescence was negative in all cases. Not all patients consented to biopsies of the eyebrows or upper limbs. Eyebrow and peripheral body hair loss is not uncommon in FFA-a finding that is likely underreported. We have demonstrated that alopecia of the upper limbs in FFA is indeed common and, histopathologically, shows features of lichen planopilaris and scarring, similar to findings in the scalp and eyebrows. Consequently, the process of lichen planopilaris with scarring alopecia is generalized rather than localized only to the frontal scalp and eyebrows.

Chemotherapy-induced hair loss is one of the most serious and feared adverse effects of cancer therapy. Almost all traditional chemotherapeutic agents induce a more or less severe alopecia. At present, there is no effective treatment capable of preventing this damage. Several different experimental approaches, using various animal models, have been investigated over the last years, with promising results. Sulphur-containing amino acids (cystine, cysteine) are essential components for the health of normal hair. L-Cystine is used in the treatment of various forms of alopecia. Vitamin B6 plays an important role in the development and maintenance of the skin and it is useful in reducing hair loss. In the present study, we demonstrated that the combined oral administration at high dosages of L-cystine (1,600 or 800 mg/kg body weight/day) and vitamin B6 (160 or 80 mg/kg body weight/day) is an effective chemopreventive treatment against alopecia induced by doxorubicin treatment (1.1 mg/kg body weight intravenously) in C57BL/6 mice.

Alopecia with mental retardation (APMR) is a very rare disorder. In this study, we report on a consanguineous Pakistani family (AP91) with mild-to-moderate intellectual disability, adolescent alopecia and dentogingival abnormalities. Using homozygosity mapping, linkage analysis and exome sequencing, we identified a novel rare missense variant c.898G>A (p.(Glu300Lys)) in ITGB6, which co-segregates with the phenotype within the family and is predicted to be deleterious. Structural modeling shows that Glu300 lies in the β-propeller domain, and is surrounded by several residues that are important for heterodimerization with α integrin. Previous studies showed that ITGB6 variants can cause amelogenesis imperfecta in humans, but patients from family AP91 who are homozygous for the c.898G>A variant present with neurological and dermatological features, indicating a role for ITGB6 beyond enamel formation. Our study demonstrates that a rare deleterious variant within ITGB6 causes not only dentogingival anomalies but also intellectual disability and alopecia. PMID:26695873

Metabolism by the gut microbiota affects host physiology beyond the gastrointestinal tract. Here, we find that antibiotic-induced dysbiosis, in particular, overgrowth of Lactobacillus murinus (L. murinus), impaired gut metabolic function and led to the development of alopecia. While deprivation of dietary biotin per se did not affect skin physiology, its simultaneous treatment with vancomycin resulted in hair loss in specific pathogen-free (SPF) mice. Vancomycin treatment induced the accumulation of L. murinus in the gut, which consumes residual biotin and depletes available biotin in the gut. Consistently, L. murinus induced alopecia when monocolonized in germ-free mice fed a biotin-deficient diet. Supplementation of biotin can reverse established alopecia symptoms in the SPF condition, indicating that L. murinus plays a central role in the induction of hair loss via a biotin-dependent manner. Collectively, our results indicate that luminal metabolic alterations associated with gut dysbiosis and dietary modifications can compromise skin physiology. Copyright © 2017.

2005-01-01

Frontal fibrosing alopecia is a variety of cicatricial alopecia characterized by a band of frontal/frontoparietal hair recession and marked decrease or a complete loss of the eyebrows, typically observed in women who are postmenopausal. The purpose of this study was to report clinical and histopathologic findings and results of treatment in a group of women affected by the disease. A total of 14 women with alopecia of the frontal hairline were evaluated from June 2000 through July 2003 in our outpatient consultation for hair disorders. Clinical examination revealed a band of symmetric recession of the frontoparietal hairline extending to the preauricular areas associated with loss of follicular orifices, mild skin atrophy, and perifollicular erythema at the scalp margin. In all, 9 patients also had partial or total loss of the eyebrows. The histologic features of the scalp specimens were similar in all our patients with a reduction of the number of hair follicles, and a high number of intermediate and velluslike follicles. Intemediate and velluslike follicles were more commonly affected than terminal follicles by the lymphocytic inflammatory infiltrate and perifollicular fibrosis. Frontal fibrosing alopecia is a cicatricial alopecia that follows destruction of hair follicles by an inflammatory lymphocytic infiltrate that is localized around the upper portion of the hair follicle. It differs from lichen planopilaris because the lymphocytic infiltrate and fibrosis affect selectively the intermediate and the velluslike follicles of the frontal margin and eyebrows. The reason for this selective involvement is still unknown. Frontal fibrosing alopecia may represent a variety of lichen planopilaris with selective involvement of certain androgen-dependent areas. The affected follicles may have typical biologic markers that could explain the clinical and histologic features found in the disease. It is interesting to note that some of the patients treated with finasteride (2.5 mg/d) showed an arrest in the progression of the disease. Even if there is no proof for a hormonal basis of the disease, the effectiveness of finasteride in some patients may indicate that androgens might be partially responsible of the pathogenesis of the disease.

Preventing chemotherapy-induced alopecia.

Chemotherapy-induced alopecia is now potentially preventable. Although scalp tourniquets and hypothermia are neither universally applicable nor always successful, they represent simple and relatively inexpensive methods for reducing hair loss. When successful, these techniques help maintain the patient's self-image and thereby diminish the devastating psychologic effects that accompany a diagnosis of cancer.

Steven Kossards postmenopausal frontal fibrosing alopecia (PFFA)--a therapeutic dilemma.

2010-01-01

Steven Kossard described a new type of hair loss that he named frontal postmenopausal fibrosing alopecia (PFFA). In some of his patients he observed a symmetric regression of the frontal hair line. The eyebrows of the patients were also often affected. The histology of the lesions showed lichen planopilaris. Several cases of frontal fibrosing alopecia have been described- almost all of them in elderly women. We report a women with postmenopausal frontal fibrosing alopecia of Kossard. In our patient there were no other clinical signs of lichen planus on the rest of the body After systemic and local therapy with corticosteroids we were able to observe a termination in the disease. In the subsequent 6-month control period no regrowth of the hair follicles was found. Even if there is no proof for a hormonal basis of the disease, the effectiveness of finasteride in some patients may indicate that androgens might be partially responsible of the pathogenesis of the disease. The local and systemic medication with corticosteroids are not able to bring to a permanent remission and secondary growth of the hair follicles in the affected areas and this brings to the necessity of more invasive or innovative therapeutic methods, like skin transplantation and additional application of medicaments like blockers of the 5/alpha reductase, which have proven their capacity in the androgenetic male alopecia.

Minoxidil is efficacious in inducing hair growth in patients with androgenetic alopecia by inducing hair follicles to undergo transition from the early to late anagen phase. Although the efficacy of 1% topical minoxidil has been confirmed in Japan, no controlled study of 5% topical minoxidil has been conducted using male Japanese subjects. The objective of this trial was to verify the superiority in clinical efficacy of 5% topical minoxidil to 1% topical minoxidil in a double-blind controlled study with male, Japanese androgenetic alopecia patients as the subjects. The trial included 300 Japanese male patients aged 20 years or older with androgenetic alopecia who were administered either 5% topical minoxidil (n = 150) or 1% topical minoxidil (n = 150) for 24 weeks. The mean change from the baseline in non-vellus hair/cm(2), the primary efficacy variable, was 26.4 (n = 142) in the 5% topical minoxidil group and 21.2 (n = 144) in the 1% topical minoxidil group at 16 weeks, the main time point for the evaluation. The difference between the groups was significant (P = 0.020). The incidence of adverse events was 8.7% (13/150) in the 5% group and 5.3% (8/150) in the 1% group, with no significant difference between the groups (chi(2)-test: P = 0.258). Our findings confirmed the superiority of 5% topical minoxidil to 1% topical minoxidil in treating Japanese men with androgenetic alopecia.

Azathioprine (AZA)-induced leukopenia is a relatively common complication in Korean patients. In addition to variation in TPMT (thiopurine S-methyltransferase), the NUDT15 p.R139C variant was recently identified to have a strong association with AZA-induced leukopenia. We investigated these associations in Korean patients undergoing AZA treatment with various neurological diseases. Among 84 enrolled patients, 20 (23.8%; 7 early, 13 late) exhibited leukopenia. The NUDT15 p.R139C variant was associated with leukopenia (OR: 11.844, 95% CI 3.984-36.024, p=1.327 × 10 -5 ). The allelic frequency of NUDT15 p.R139C was as high as 10.7% and the frequency of the C/C, C/T, and T/T genotypes was 84.5, 10.7, and 5.9%, respectively. All T/T homozygous patients (5/5) developed early severe-grade leukopenia (white blood cells <1000mm -3 ) and severe alopecia. NUDT15 p.R139C was strongly associated with early leukopenia and severe alopecia (OR for early leukopenia: 107.624, 95% CI 18.857-614.250, p=1.403 × 10 -7 , OR for severe alopecia: 77.152, 95% CI 17.378-342.526, p=1.101 × 10 -8 ). The sensitivity and specificity for predicting AZA-induced early leukopenia were 85.7% and 92.2%, respectively. Therefore, the NUDT15 p.R139C variant is common and strongly associated with AZA-induced early leukopenia and severe alopecia in Korean patients with various neurological diseases.

To analyze the clinical and histological features of permanent alopecia following a sequential fluorouracil/epirubicin/cyclophosphamide (FEC) and docetaxel regimen for adjuvant breast cancer treatment. Women treated for breast cancer by a sequential adjuvant FEC and docetaxel regimen who developed permanent alopecia diagnosed between 2007 and 2011 were identified from the Department of Dermatology (Saint-Eloi Hospital, Montpellier, France) and the Department of Medical Oncology (CRLC Val d'Aurelle, Montpellier, France). Data were collected regarding demographics, type of cancer, delay of onset after chemotherapy, Dermatology Life Quality Index (DLQI), clinical description of the lesions, scalp biopsies, laboratory explorations investigating steroid hormonal, iron, zinc and thyroid status, therapy and outcome. Twenty white Caucasian females were included. Hair loss presented with a moderate or intense androgenetic-like pattern of scalp alopecia. Biopsy specimen examinations were normal or displayed the androgenetic-like pattern. Laboratory explorations ruled out iron or zinc deficiency and thyroid disorders and confirmed hormonal menopause without hyperandrogenism. The overall mean DLQI score reflected the distressing psychological consequences in the patients' lives. No spontaneous regrowth of the scalp hair was noted. Treatment including vitamins, minoxidil, psoralen and ultraviolet A therapy and spironolactone proved to be ineffective. Permanent and severe alopecia is a newly reported complication of the FEC 100-docetaxel breast cancer regimen.

Background There is growing interest in alopecia among the general population. Many people obtain information from easily accessible media rather than from doctors; thus, the media can play an important role in shaping public opinion. Objective The goal of this study was to evaluate the content and reliability of newspaper articles on alopecia. Methods Newspapers were categorized into three groups: one group of print newspapers and two groups of online newspapers. Online newspapers were further divided into two groups according to type of publishing company; one publishes both print and online newspapers and the other publishes online newspapers only. The most frequently subscribed or circulated newspaper in each group was selected. Articles containing information on alopecia were selected from 3 years of each newspaper and evaluated for reliability. Results Most articles in each group used the general term “alopecia” instead of naming a specific hair loss disease. The majority of articles were based on consultation with experts. Assessment of the accuracy of articles with three grade scales showed that the percentage with high accuracy was 38.9%, 47.2%, and 23.3%. Assessment of reliability scores for five selected articles in each group showed that there were statistically significant differences between common readers and dermatologists (p<0.05). Conclusion The results of this study suggest that closer monitoring of the media is required to supply easily accessible, balanced, and trustworthy information regarding alopecia. PMID:29853745

ABSTRACT Androgenetic alopecia is the most common form of hair loss. Minoxidil has been approved for the treatment of hair loss, however its mechanism of action is still not fully clarified. In this study, we aimed to elucidate the effects of 5% minoxidil topical foam on gene expression and activation of signaling pathways in vertex and frontal scalp of men with androgenetic alopecia. We identified regional variations in gene expression and perturbed signaling pathways using in silico Pathway Activation Network Decomposition Analysis (iPANDA) before and after treatment with minoxidil. Vertex and frontal scalp of patients showed a generally similar response to minoxidil. Both scalp regions showed upregulation of genes that encode keratin associated proteins and downregulation of ILK, Akt, and MAPK signaling pathways after minoxidil treatment. Our results provide new insights into the mechanism of action of minoxidil topical foam in men with androgenetic alopecia. PMID:28594262

Er:YAG laser-assisted hair transplantation in cicatricial alopecia.

Autologous hair transplantation and its combination with flap or reduction procedures is a common surgical approach to cover defects in cicatricial alopecias. Due to the poor recipient conditions present in scar tissue, it is crucial to minimize the trauma exerted on implantation holes in order to achieve good transplantation results. We sought to evaluate the "cold"-ablative properties of the Er:YAG laser for the generation of recipient holes in cicatricial alopecia. Patients with cicatricial alopecia of diverse etiology were treated with Er:YAG laser-assisted hair transplantation. Mini- or micrografts were inserted into recipient holes ablated with a pulse energy of 900-1200 mJ and a spot size of 1.0-1.6 mm. A fluence of 80-120 J/cm2 and 8-12 pulses gave an almost ideal combination of minimal thermal damage and tissue ablation down to the subcutis. With an apparent mini- and micrograft survival of 95% we achieved good cosmetic results after two to five transplant sessions in all patients. The Er:YAG laser is a novel effective tool to ablate recipient holes for autologous hair transplantation in cicatricial alopecia.

This study evaluated the clinical and histopathological features and results of light and electron scanning microscopy assessments of follicular dysplasia in five Weimar Pointers. The data were compared with those obtained in three normal Weimaraners. In our study, this dermatosis affected young adults that showed progressive alopecia of the trunk (head and limbs were spared) associated with recurrent folliculitis/furunculosis. Exclusion of other dermatoses and the presence of histopathological lesions and hair shafts abnormalities seen in light and/or scanning electron microscopy similar to colour dilution alopecia led to the diagnosis of follicular dysplasia. The lesions we observed are the same as those described previously in colour dilution alopecia, but they were less pronounced in all our samples.

We evaluated the role of psychic factors in the etiopathogenesis of alopecia areata on the basis of Eysenck's Personality Inventory adapted by Choynowski. 55 patients were tested (28 women and 27 men). The control group consisted of 50 volunteers. The analysis of the results showed that the neurotic type of personality was predominant in the group of patients (43.64%). Neurotic personality found in such a high percentage of the patients with alopecia areata may be an additional element in the group of psychic factors that possibly have some influence on the development of the disease.

We report for the first time on hair regrowth in alopecia areata of the scalp achieved with the 308-nm xenon-chloride excimer laser in a prospective side-by-side trial. The alopecia areata had shown progression over a period of three years, and various treatments had not been effective. Out of a number of affected areas, one representative lesion was chosen; one half of it was treated, the other half remained untreated. After 27 sessions (200 - 4000 mJ/cm2, cumulative dose 52.6 J/cm2) over 3 months, only the treated area showed hair growth; which suggests that this was most probably not a spontaneous remission.

Vitiligo is a common chronic acquired disease of pigmentation whose etiology is unknown, which usually occurs with asymptomatic whitish patch or macule. Although several hypotheses have been proposed in the literature, the leading theory is still the auto-immune etiology linked to specific genetic mutations. Vitiligo can also be associated with several autoimmune diseases, including autoimmune thyroid diseases, alopecia areata, and halo nevi. Sensorineural hearing loss was reported in several vitiligo patients due to a reduction in the number of melanocytes contained in the membranous labyrinth of the inner ear. Because of its complexity, several therapeutic options are available to treat this systemic disease. Copyright © 2015 Elsevier B.V. All rights reserved.

Interferon-gamma(-/-) (IFN-gamma(-/-)) and IFN-gamma(+/+) C57BL/6 mice (3 weeks of age) completed the production of morphogenesis-derived hair. Around 6 weeks of age, however, most of the IFN-gamma(-/-) but none of the IFN-gamma(+/+) mice began to lose hairs in the dorsal and occipital areas in the absence of inflammatory reactions, and the alopecia was sustained for at least several 10-week periods of observation. A single subcutaneous injection of IFN-gamma to IFN-gamma(-/-) mice at 3, but not 4, 5, or 8 weeks of age could protect all the mice from alopecia, revealing that the lack of IFN-gamma around 3 weeks of age is directly responsible for the alopecia. Histologic features showed that the hair follicles of the IFN-gamma(+/+) mice passed through the anagen (4-5 weeks of age) and catagen/telogen ( approximately 6 weeks of age) phases, whereas those of IFN-gamma(-/-) mice (5 weeks of age or older) stayed in the anagen phase. TUNEL and bromodeoxyuridine experiments suggested that an arrest with unlimited DNA synthesis of the hair cycle in the anagen phase by the lack of IFN-gamma-dependent apoptosis in the midfollicle region and diffuse shedding of previously formed hair induced alopecia in IFN-gamma(-/-) mice.

In androgenetic alopecia, a number of botanicals are available that can effectively slow or reduce hair loss and inflammation or stimulate partial hair regrowth. The aim of this study was to provide a descriptive overview of the impact and production of literature on botanicals used for androgenetic alopecia and to perform a citation analysis of the related research articles. We searched for "alopecia" OR "androgenetic alopecia" OR "hair loss" AND "Camelia sinensis" OR (and other 15 botanicals) in ARTICLE (Title/Abstract/Keyword) in Scopus database. A total of 29 references, that is, research articles, were retrieved by SCOPUS search, and 93.1% had been published since 2000. The majority (48.3%) describe applications of hair grow stimulants, followed by inhibitors of 5-alpha-reductase applications (27.6%), and studies concerning inhibitors of inflammation (24.1%). The citation analysis revealed a growing interest for this topic and the papers on hair grow stimulants are most cited. Citation trend of inhibition of 5-alpha-reductase articles is growing in the last years. This study has highlighted three important aspects: (1) growing interest for this topic; (2) evidences mainly in hair grow stimulants and recently in the inhibition of 5-alpha-reductase, as demonstrated by article and citation counts across years; (3) in addition, all major studies have been focused on green tea epigallocatechin-3-gallate, Serenoa repens, Citrullus colocynthis and Cuscuta reflexa. © 2015 Wiley Periodicals, Inc.

Cyclin-dependent kinase (CDK) inhibitors emerge as efficacious agents in hormone positive metastatic breast cancer with more acceptable toxicity profiles than cytotoxic chemotherapy. However, some adverse effects such as fatigue, alopecia and stomatitis, vastly concern patients. The search was conducted in PubMed, American Society of Clinical Oncology meeting library, European Society for Medical Oncology meeting abstract, and the San Antonio meeting abstract databases. We identified phase 2 or 3 trials recruiting patients with breast cancer, randomized to receive hormonal treatment plus either CDK4/6 inhibitors or placebo. We considered studies providing incidence of fatigue, alopecia and stomatitis relevant. One thousand records were screened. 34 studies were considered relevant. Four studies were found to be eligible for meta-analysis with a total of 2007 patients. The relative risk for all grade fatigue was 1.34 [95% CI: 1.17-1.54, p < 0.0001], for all grade alopecia was 2.14 [95% CI: 1.23-3.73, p = 0.007], and for all grade stomatitis 4.87 [95% CI: 2.11-11.24, p = 0.0002]. In addition, the relative risk for high grade fatigue was 2.40 [95% CI: 1.10-5.26, p = 0.03]. CDK4/6 inhibitors were associated with an increased risk of fatigue, alopecia and stomatitis. Further studies with self-reported questionnaires may elucidate the impact of the increased risk of these selected adverse effects on the patients' quality of life.

Alopecia-contractures-dwarfism mental retardation syndrome (ACD syndrome; OMIM 203550) is a very rare genetic disorder with distinct features. To our knowledge, there have been four cases documented to date. In addition, another three patients, previously described as having IFAP syndrome (OMIM %308205), may also have ACD syndrome. We report on one patient with short stature, total alopecia, ichthyosis, photophobia, seizures, ectrodactyly, vertebral anomalies, scoliosis, multiple contractures, mental retardation, and striking facial and other features (e.g. microdolichocephaly, missing eyebrows and eyelashes, long nose, large ears) consistent with ACD syndrome. Results of laboratory testing in the literature case reports were normal, although in none of them, array-CGH (microarray-based comparative genomic hybridization) analysis was performed. In conclusion, the combination of specific features, including total alopecia, ichthyosis, mental retardation, and skeletal anomalies are suggestive of ACD syndrome. We propose that children with this syndrome undergo a certain social pediatric protocol including EEG diagnostics, ophthalmological investigation, psychological testing, management of dermatologic and orthopedic problems, and genetic counseling.

We conducted a 16-week double-blind randomized controlled single-center trial to evaluate the safety and efficacy of dermal rice bran supercritical CO2 extract (RB-SCE) in the treatment of androgenic alopecia. Fifty alopecia patients were randomly assigned to the experimental and placebo groups. The experimental group received a dermal application of 0.5% RB-SCE (8 mL/d) to the head skin for 16 weeks while the control group received a dermal application of placebo. Changes in hair count, diameter, and density were evaluated with a Folliscope(®). Patient satisfaction was evaluated via questionnaire and clinical photographs were rated by dermatologists. The results showed that RB-SCE significantly increased hair density and hair diameter in male subjects. Patient satisfaction and the evaluation of photographs by dermatologists also confirmed the effectiveness of RB-SCE in the treatment of alopecia. No adverse reactions related to RB-SCE were reported. Therefore, RB-SCE shows promise for use in functional cosmetics and pharmaceuticals.

Frontal fibrosing alopecia (FFA) is a primary lymphocytic cicatricial alopecia characterized by a progressive band-like recession of the frontotemporal hairline and frequent loss of the eyebrows. It predominantly affects postmenopausal women. Coexistence of FFA and vitiligo is rarely reported in the literature. We retrospectively studied 20 cases diagnosed with FFA in a 14-month period in our Department. Among them, there were 2 cases, a 72-year-old woman and a 48-year-old man, who developed FFA on preexisting vitiligo of the forehead. Anatomical colocalization of the two dermatoses supports the notion that a causal link may exist and their association may not be coincidental. We suggest that interrelated immunologic events and pathologic processes may underlie both these skin conditions.

We tested the significance of psychic factors in the etiopathogenesis of alopecia areata. We analysed the patient on the basis of a detailed examination based on the case history, including important events in his/her life, personality traits, serious events and the loss of emotional attachment. General important events happened to 80% of the patients, personality traits able to cause the disease were present in 73%, serious events in 62% and the loss of emotional attachment was also found in 62% of the patients. We tested 60 patients (31 women and 29 men). The evidence obtained from the detailed examination based on case histories indicated significantly frequent occurrence of the psychic factors preceding the occurrence of alopecia areata.

Alopecia areata is an immune-mediated disorder, occurring with the highest observed frequency in the rare recessive autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) syndrome caused by mutations of the autoimmune regulator (AIRE) gene on chromosome 21q22.3. We have previously detected association between alopecia areata and a single nucleotide polymorphism (SNP) in the AIRE gene in patients without APECED, and we now report the findings of an extended examination of the association of alopecia areata with haplotype analysis including six SNPs in the AIRE gene: C-103T, C4144G, T5238C, G6528A, T7215C and T11787C. In Caucasian groups of 295 patients and 363 controls, we found strong association between the AIRE 7215C allele and AA [P = 3.8 x 10(-8), OR (95% CI): 2.69 (1.8-4.0)]. The previously reported association between AA and the AIRE 4144G allele was no longer significant on correction for multiple testing. The AIRE haplotypes CCTGCT and CGTGCC showed a highly significant association with AA [P = 6.05 x 10(-6), 9.47 (2.91-30.8) and P = 0.001, 3.51 (1.55-7.95), respectively]. To select the haplotypes most informative for analysis, we tagged the polymorphisms using SNPTag software. Employing AIRE C-103T, G6528A, T7215C and T11787C as tag SNPs, two haplotypes were associated with AA; AIRE CGCT and AIRE CGCC [P = 3.84 x 10(-7), 11.40 (3.53-36.9) and P = 3.94 x 10(-4), 2.13 (1.39-3.24) respectively]. The AIRE risk haplotypes identified in this study potentially account for a major component of the genetic risk of developing alopecia areata.

2018-06-01

The market for home-use photobiomodulation devices to treat androgenetic alopecia has rapidly expanded, and the Food and Drug Administration (FDA) has recently cleared many devices for this purpose. Patients increasingly seek the advice of dermatologists regarding the safety and efficacy of these hair loss treatments. The purpose of this guide was threefold: (1) to identify all home-use photobiomodulation therapy devices with FDA-clearance for treatment of androgenetic alopecia; (2) to review device design, features and existing clinical evidence; and (3) to discuss practical considerations of photobiomodulation therapy, including patient suitability, treatment goals, safety, and device selection. A search of the FDA 510(k) Premarket Notification database was conducted using product code "OAP" to identify all home-use devices that are FDA-cleared to treat androgenetic alopecia. Thirteen commercially available devices were identified and compared. Devices varied in shape, wavelength, light sources, technical features, price, and level of clinical evidence. To date, there are no head-to-head studies comparing the efficacy of these devices. Photobiomodulation therapy devices have an excellent safety profile and mounting evidence supporting their efficacy. However, long-term, high quality studies comparing these devices in diverse populations are lacking. As these devices become increasingly popular, dermatologists should be familiar with this treatment modality to add to their therapeutic armamentarium.

Alopecia is a dermatological disorder, commonly known as hair loss, which affects up to half of the Caucasian male population by middle age, and almost all (95%) Caucasian men by old age. Considering that alopecia affects so many people and that there is currently no scientifically proven treatment with few side effects, new drug-delivery systems able to improve alopecia therapy are urgently required. With this purpose in mind, the present study aimed to develop lipid nanoparticles (nanostructured lipid carriers) with the ability to incorporate and deliver anti-alopecia active compounds (minoxidil and finasteride) into the dermis and hair follicles. Lipid nanoparticles, prepared by ultrasonication method, showed mean particle sizes around 200 nm, which is sufficient for reaching the dermis and hair follicles, and zeta potential values around −30 mV, which indicates good physical stability. Over 28 days of storage, no significant variations in these parameters were observed, which indicates that all nanoformulations are stable in storage over that period. Cryo-scanning electron microscope measurements showed that all the lipid nanoparticles exhibited a spherical shape and a smooth surface regardless of their composition. Differential scanning calorimetry studies allowed the determination of phase transition temperatures and confirmed the recrystallization of the lipid nanoparticles (recrystallization index between 11% and 86%). A high loading efficiency was achieved for finasteride (between 70% and 90%), while less than 30% was achieved for minoxidil nanoparticles, over 28 days. Controlled release assays in physiological conditions demonstrated that nanoparticles loaded with minoxidil yielded a prolonged release, as desired. Penetration assays through pig ear skin demonstrated that nanoparticles loaded with minoxidil and finasteride had low levels of penetration. These results suggest that the proposed novel formulation presents several good characteristics indicating their suitability for dermal delivery of anti-alopecia active compounds. PMID:24634584

Objectives This study aimed to examine levels of social anxiety, anxiety and depression reported by people with alopecia as a result of a dermatological condition and associations with wig use. The study also sought to report on experiences of wearing wigs in social situations and the relationship with social confidence. Design A cross-sectional survey was sent by email to the Alopecia UK charity mailing list and advertised on social media. Participants Inclusion criteria were a diagnosis of alopecia, aged 13 or above and sufficient English to complete the survey. Exclusion criteria included experiencing hair loss as a result of chemotherapy treatment or psychological disorder. Participants (n=338) were predominantly female (97.3%), Caucasian (93.5%) and aged between 35 and 54 years (49.4%) with a diagnosis of alopecia areata (82.6%). Main outcome measures The Social Phobia Inventory measured symptoms of social anxiety, and the Hospital Anxiety and Depression Scale was used to measure symptoms of anxiety and depression. Survey questions were designed to measure the use of wigs. Open-ended questions enabled participants to comment on their experiences of wearing wigs. Results Clinically significant levels of social anxiety (47.5%), anxiety (35.5%) and depression (29%) were reported. Participants who reported worries about not wearing a wig reported significantly higher levels of depression: t(103)=3.40, p≤0.001; anxiety: t(109)=4.80, p≤0.001; and social anxiety: t(294)=3.89, p≤0.001. Wearing wigs was reported as increasing social confidence; however, the concealment it afforded was also reported as both reducing fear of negative evaluation and maintaining anxiety. Discussion Overall, 46% of participants reported that wearing a wig had a positive impact on their everyday life with negative experiences related to fears of the wig being noticed. Psychological interventions alongside wig provision would be beneficial for people living with alopecia. PMID:28473521

Hormone studies have demonstrated the androgen-dependent character of female androgenetic alopecia, but there have been few controlled studies of therapies for alopecia in women. To compare topical minoxidil 2% and cyproterone acetate in the treatment of female alopecia. Sixty-six women with female-pattern alopecia were randomly assigned for 12 cycles into two groups, 33 received two local applications (2 mL day-1) of topical minoxidil 2% plus combined oral contraceptive and 33 received cyproterone acetate 52 mg day-1 plus ethinyl oestradiol 35 microg for 20 of every 28 days. A mean reduction of 2.4 +/- 6.2 per 0.36 cm2 in hairs of diameter > 40 microm was observed in the cyproterone acetate group (P = 0.05) and a mean increase of 6.5 +/- 9 per 0.36 cm2 in the minoxidil group (P < 0.001). Comparison of the total number of hairs at 12 months and the body mass index (BMI) revealed a borderline positive correlation in the cyproterone acetate group (r = 0.39, P = 0.06) and a negative correlation in the minoxidil group (r = -0.42, P < 0.05). No significant difference was observed in the total number of hairs among cyproterone acetate patients according to the presence or absence of other symptoms of hyperandrogenism, whereas in the minoxidil group, the total number of new hairs was higher in patients with isolated alopecia (Delta = 8.1; P < 0.05). Variations in scalp seborrhoea were significant in both groups, but the result was better (for acne and hirsutism as well) in the cyproterone acetate group than in the minoxidil group (P < 0.001). Minoxidil treatment was more effective in the absence of other signs of hyperandrogenism, hyperseborrhoea, and menstrual cycle modifications when the BMI was low, and when nothing argued in favour of biochemical hyperandrogenism. Cyproterone acetate treatment was more effective when other signs were present and when the BMI was elevated, factors that favoured a diagnosis of biochemical hyperandrogenism.

A 75-year-old woman presented with a 3-year history of progressive loss of her eyebrow hair and with frontal-parietal hairline recession. Multiple biopsy specimens supported a histopathologic diagnosis of lichen planopilaris. With these histolopathologic findings, and the patient's clinical presentation, a diagnosis of frontal fibrosing alopecia was made. Treatment to date with topical glucocorticoid preparations, intralesional triamcinolone injections, and tacrolimus ointment have been unsuccessful.

More than half of all people diagnosed with cancer receive chemotherapy, and approximately 65% of these develop chemotherapy-induced alopecia (CIA), a side-effect that can have considerable negative psychological repercussions. Currently, there are very few animal models available to study the mechanism and prevention of CIA. To develop a clinically relevant adult rat model for CIA. We first tested whether neonatal pigmented Long-Evans (LE) rats developed alopecia in response to the chemotherapeutic agents etoposide and cyclophosphamide. We then determined whether the rats developed CIA as adults. In the latter experiment, rat dorsal hair was clipped during the early telogen stage to synchronize the hair cycle, and starting 15 days later, the rats were treated with etoposide for 3 days. Neonatal LE pups developed CIA in response to etoposide and cyclophosphamide, similar to other murine models for CIA. Clipping of the hair shaft during early telogen resulted in synchronized anagen induction and subsequent alopecia after etoposide treatment in the clipped areas only. Hair follicles in the clipped areas had the typical chemotherapy-induced follicular dystrophy (dystrophic catagen). When the hair in the pigmented alopecic areas regrew, it had normal pigmentation. A novel, pigmented adult rat model has been established for CIA. By hair-shaft clipping during early telogen, synchronized anagen entry was induced, which resulted in alopecia in response to chemotherapy. This is the first clinically relevant adult rat model for CIA, and will be a useful tool to test agents for the prevention and treatment of CIA. © The Author(s).

Frontal fibrosing alopecia: clinical presentations and prognosis.

Frontal fibrosing alopecia is an uncommon condition characterized by progressive frontotemporal recession due to inflammatory destruction of hair follicles. Little is known about the natural history of this disease. To determine the clinical features and natural history of frontal fibrosing alopecia. We studied the cases notes of patients diagnosed with frontal fibrosing alopecia from 1993 to 2008 at the Royal Hallamshire Hospital, Sheffield. There were 18 patients aged between 34 and 71 years. Three were premenopausal. All had frontotemporal recession with scarring. This was associated with partial or complete loss of eyebrows in 15 patients while four had hair loss at other sites. One had keratosis pilaris-like papules on the face, and one had follicular erythema on the cheeks. Three patients had oral lichen planus, of whom two also had cutaneous lichen planus affecting other sites of the body. Treatments given included intralesional triamcinolone acetonide, 0.1% tacrolimus ointment and oral hydroxychloroquine. Progression of frontotemporal recession was seen in some patients, but not all. In one patient the hair line receded by 30 mm over 72 months, whereas in another patient there was no positional change in the hair line after 15 years. Frontal fibrosing alopecia is more common in postmenopausal women, but it can occur in younger women. It may be associated with mucocutaneous lichen planus. Recession of the hair line may progress inexorably over many years but this is not inevitable. It is not clear whether or not treatment alters the natural history of the disease - the disease stabilized with time in most of the patients with or without continuing treatment.

Mechanism of action of minoxidil in the treatment of androgenetic alopecia is likely mediated by mitochondrial adenosine triphosphate synthase-induced stem cell differentiation.

Topical minoxidil is the only topical drug approved by the US Food and Drug Administration (FDA) for the treatment of androgenetic alopecia. However, the exact mechanism by which minoxidil stimulates anagen phase and promotes hair growth is not fully understood. In the late telegen phase of the hair follicle growth cycle, stem cells located in the bulge region differentiate and re-enter anagen phase, a period of growth lasting 2-6 years. In androgenetic alopecia, the anagen phase is shortened and a progressive miniaturization of hair follicles occurs, eventually leading to hair loss. Several studies have demonstrated that minoxidil increases the amount of intracellular Ca2+, which has been shown to up-regulate the enzyme adenosine triphosphate (ATP) synthase. A recent study demonstrated that ATP synthase, independent of its role in ATP synthesis, promotes stem cell differentiation. As such, we propose that minoxidil induced Ca2+ influx can increase stem cell differentiation and may be a key factor in the mechanism by which minoxidil facilitates hair growth. Based on our theory, we provide a roadmap for the development of a new class of drugs for the treatment of androgenetic alopecia.

Hyaluronic acid (HA) filler injection is widely used for soft-tissue augmentation. Complications associated with HA filling are not uncommon; however, HA-induced alopecia is a rarely reported complication that could result in severe secondary psychological trauma. The etiology, clinical traits, treatment strategies, outcomes, and possible reversibility of HA-induced alopecia have not been characterized. Here, we report a case in which bilateral temple injections of 6.5 mL of HA led to persistent pain over the left scalp for several days. Although the pain was relieved at day 9 after 600 U of hyaluronidase were injected in the left temple, the patient developed localized alopecia at the left temporoparietal region with central skin necrosis at day 15. After topical applications of recombinant bovine basic fibroblast growth factor gel and 2% minoxidil spay, the necrotic skin wound was healed at day 42. Hair regrowth and normal hair density were restored at day 74. Analyses of Doppler ultrasound examinations and histopathology of the skin biopsy suggested that mild ischemia of the left temporoparietal region led to reversible alopecia, while the permanent hair loss in the left parietal area was associated with severe skin ischemia. Therefore, the key to treatment would be to focus on the effective correction of severe ischemia-induced skin necrosis to prevent permanent hair loss.

Most traditional cytotoxic anticancer agents ablate the rapidly dividing epithelium of the hair follicle and induce alopecia (hair loss). Inhibition of cyclin-dependent kinase 2 (CDK2), a positive regulator of eukaryotic cell cycle progression, may represent a therapeutic strategy for prevention of chemotherapy-induced alopecia (CIA) by arresting the cell cycle and reducing the sensitivity of the epithelium to many cell cycle-active antitumor agents. Potent small-molecule inhibitors of CDK2 were developed using structure-based methods. Topical application of these compounds in a neonatal rat model of CIA reduced hair loss at the site of application in 33 to 50% of the animals. Thus, inhibition of CDK2 represents a potentially useful approach for the prevention of CIA in cancer patients.

Development of Uniform Protocol for Alopecia Areata Clinical Trials.

Developing a successful treatment for alopecia areata (AA), clearly has not been at the forefront of the agenda for new drug/device development among the pharmaceutical and medical device industry. The National Alopecia Areata Foundation (NAAF), a patient advocacy group, initiated a plan to facilitate and drive clinical research toward finding safe and efficacious treatments for AA. As such, Alopecia Areata Uniform Protocols for clinical trials to test new treatments for AA were developed. The design of the uniform protocol is to accomplish the development of a plug-and-play template as well as to provide a framework wherein data from studies utilizing the uniform protocol can be compared through consistency of inclusions/exclusions, safety, and outcome assessment measures. A core uniform protocol for use by pharmaceutical companies in testing proof of concept for investigational products to treat AA. The core protocol includes standardized title, informed consent, inclusion/exclusion criteria, disease outcome assessments, and safety assessments. The statistical methodology to assess successful outcomes will also be standardized. The protocol as well as the informed consent form has been approved in concept by Liberty IRB and is ready to present to pharmaceutical companies.

Amelanocytic anhidrotic alopecia areata-like phenotype after allogeneic hematopoietic cell transplant.

Diffuse alopecia areata or canities subita is a rare variant of alopecia in which hair loss is associated with regrowth of white hairs and possible lightening of the skin. Preferential loss of pigmented hair in this disorder may be related to the melanin pigment system and/or melanocytes. Acquired generalized anhidrosis can be associated with autoimmune disease, cancer, graft-vs-host disease, or medications or can be idiopathic. Extensive anhidrosis may cause hyperpyrexia on exposure to heat, and protection from overheating is essential. A 38-year-old man with idiopathic autoimmune aplastic anemia developed permanent diffuse skin and hair whitening and generalized anhidrosis after a successful allogeneic hematopoietic stem cell transplant. Results of a histopathologic examination, which has previously not been reported in this disease, demonstrated a complete lack of epidermal and follicular melanocytes and a dense perifollicular and periadnexal lymphocytic infiltrate. The hair- and skin-lightening phenomena in diffuse alopecia areata may be the result of an overstimulated immune system that targets epidermal and follicular melanocytes. Destruction results in irreversible pigmentary loss of the skin. In a patient with multiple risk factors for anhidrosis, a specific cause may be difficult to determine.

Treatments for androgenetic alopecia constitute a multi-billion-dollar industry, however, currently available therapeutic options have variable efficacy. Consequently, in recent years small biotechnology companies and academic research laboratories have begun to investigate new or improved treatment methods. Research and development approaches include improved formulations and modes of application for current drugs, new drug development, development of cell-based treatments, and medical devices for modulation of hair growth. Areas covered: Here we review the essential pathways of androgenetic alopecia pathogenesis and collate the current and emerging therapeutic strategies using journal publications databases and clinical trials databases to gather information about active research on new treatments. Expert opinion: We propose that topically applied medications, or intra-dermal injected or implanted materials, are preferable treatment modalities, minimizing side effect risks as compared to systemically applied treatments. Evidence in support of new treatments is limited. However, we suggest therapeutics which reverse the androgen-driven inhibition of hair follicle signaling pathways, such as prostaglandin analogs and antagonists, platelet-rich plasma (PRP), promotion of skin angiogenesis and perfusion, introduction of progenitor cells for hair regeneration, and more effective ways of transplanting hair, are the likely near future direction of androgenetic alopecia treatment development.

How to promote and preserve eyelid health.

PubMed

Benitez-Del-Castillo, Jose M

2012-01-01

Disorders of the lacrimal functional unit are common in ophthalmological practice, with meibomian gland dysfunction, blepharitis, and dry eye forming a significant part of the general ophthalmologist's practice. The eyelid and its associated structures form a complex organ designed to protect the fragile corneal surface and improve visual acuity. This organ is subject to a number of disorders, including meibomian gland dysfunction, dry eye syndrome, anterior blepharitis, allergic and dermatological conditions, and disorders associated with contact lens use. Although commonly described separately, disorders of the lacrimal function unit are better considered as a group of interacting pathologies that have inflammatory mediators as a central feature. Eyelid hygiene, in the sense of routine cleansing and massage of the eyelids, is well accepted in the management of many disorders of the eyelid. However, a broader concept of eyelid health may be appropriate, in which eyelid cleansing is but a part of a more complete program of care that includes screening and risk assessment, patient education, and coaching. The ophthalmologist has an important role to play in helping patients persist with routine eyelid care that may be long-term or lifelong. A number of preparations exist to make routine eyelid care both more effective and more pleasant, and might also improve compliance. Several such preparations have been devised, and are being assessed in clinical studies, and appear to be effective and preferred by patients over traditional soap and water or baby shampoo.

Macrolides in Chronic Inflammatory Skin Disorders

Long-term therapy with the macrolide antibiotic erythromycin was shown to alter the clinical course of diffuse panbronchiolitis in the late 1980s. Since that time, macrolides have been found to have a large number of anti-inflammatory properties in addition to being antimicrobials. These observations provided the rationale for many studies performed to assess the usefulness of macrolides in other inflammatory diseases including skin and hair disorders, such as rosacea, psoriasis, pityriasis rosea, alopecia areata, bullous pemphigoid, and pityriasis lichenoides. This paper summarizes a collection of clinical studies and case reports dealing with the potential benefits of macrolides antibiotics in the treatment of selected dermatoses which have primarily been classified as noninfectious and demonstrating their potential for being disease-modifying agents.

Vañó-Galván, S; Camacho, F

2017-04-01

The treatment of hair loss is an important part of clinical dermatology given the prevalence of the problem and great impact on patients' quality of life. Many new treatments have been introduced in recent years. This review summarizes the main ones in 4 groups: a) For androgenetic alopecia, we discuss new excipients for oral minoxidil, dutasteride, and finasteride as well as new forms of topical application; prostaglandin agonists and antagonists; low-level laser therapy; and regenerative medicine with Wnt signaling activators and stem cell therapy. b) For alopecia areata, Janus kinase inhibitors are reviewed. c) For frontal fibrosing alopecia, we discuss the use of antiandrogens and, for some patients, pioglitazone. d) Finally, we mention new robotic devices for hair transplant procedures and techniques for optimal follicular unit extraction.

Whole brain radiation therapy (WBRT) is widely used for the treatment of brain metastases. Cognitive decline and alopecia are recognized adverse effects of WBRT. Recently hippocampus sparing whole brain radiation therapy (HS-WBRT) has been shown to reduce the incidence of memory loss. In this study, we found that multi-field intensity modulated radiation therapy (IMRT), with strict constraints to the brain parenchyma and to the hippocampus, reduces follicular scalp dose and prevents alopecia. Suitable patients befitting the inclusion criteria of the RTOG 0933 trial received Hippocampus sparing whole brain radiation. On follow up, they were noticed to have full scalp hair preservation. 5 mm thickness of follicle bearing scalp in the radiation field was outlined in the planning CT scans. Conventional opposed lateral WBRT radiation fields were applied to these patient-specific image sets and planned with the same nominal dose of 30 Gy in 10 fractions. The mean and maximum dose to follicle bearing skin and Dose Volume Histogram (DVH) data were analyzed for conventional and HS-WBRT. Paired t-test was used to compare the means. All six patients had fully preserved scalp hair and remained clinically cognitively intact 1-3 months after HS-WBRT. Compared to conventional WBRT, in addition to the intended sparing of the Hippocampus, HS-WBRT delivered significantly lower mean dose (22.42 cGy vs. 16.33 cGy, p < 0.0001), V24 (9 cc vs. 44 cc, p < 0.0000) and V30 (9 cc vs. 0.096 cc, p = 0.0106) to follicle hair bearing scalp and prevented alopecia. There were no recurrences in the Hippocampus area. HS-WBRT, with an 11-field set up as described, while attempting to conserve hippocampus radiation and maintain radiation dose to brain inadvertently spares follicle-bearing scalp and prevents alopecia.

Observations about the natural history of aging in Cornelia de Lange syndrome (CdLS) are made, based on 49 patients from a multidisciplinary clinic for adolescents and adults. The mean age was 17 years. Although most patients remain small, obesity may develop. Gastroesophageal reflux persists or worsens, and there are early long-term sequelae, including Barrett esophagus in 10%; other gastrointestinal findings include risk for volvulus, rumination, and chronic constipation. Submucous cleft palate was found in 14%, most undetected before our evaluation. Chronic sinusitis was noted in 39%, often with nasal polyps. Blepharitis improves with age; cataracts and detached retina may occur. Decreased bone density is observed, with occasional fractures. One quarter have leg length discrepancy and 39% scoliosis. Most females have delayed or irregular menses but normal gynecologic exams and pap smears. Benign prostatic hypertrophy occurred in one male prior to 40 years. The phenotype is variable, but there is a distinct pattern of facial changes with aging. Premature gray hair is frequent; two patients had cutis verticis gyrata. Behavioral issues and specific psychiatric diagnoses, including self-injury, anxiety, attention-deficit disorder, autistic features, depression, and obsessive-compulsive behavior, often worsen with age. This work presents some evidence for accelerated aging in CdLS. Of 53% with mutation analysis, 55% demonstrate a detectable mutation in NIPBL or SMC1A. Although no specific genotype–phenotype correlations have been firmly established, individuals with missense mutations in NIPBL and SMC1A appear milder than those with other mutations. Based on these observations, recommendations for clinical management of adults with CdLS are made. PMID:17640042

Drug discovery for alopecia: gone today, hair tomorrow

Santos, Zenildo; Avci, Pinar; Hamblin, Michael R

2015-01-01

Introduction Hair loss or alopecia affects the majority of the population at some time in their life, and increasingly, sufferers are demanding treatment. Three main types of alopecia (androgenic [AGA], areata [AA] and chemotherapy-induced [CIA]) are very different, and have their own laboratory models and separate drug-discovery efforts. Areas covered In this article, the authors review the biology of hair, hair follicle (HF) cycling, stem cells and signaling pathways. AGA, due to dihydrotesterone, is treated by 5-α reductase inhibitors, androgen receptor blockers and ATP-sensitive potassium channel-openers. AA, which involves attack by CD8+NK group 2D-positive (NKG2D+) T cells, is treated with immunosuppressives, biologics and JAK inhibitors. Meanwhile, CIA is treated by apoptosis inhibitors, cytokines and topical immunotherapy. Expert opinion The desire to treat alopecia with an easy topical preparation is expected to grow with time, particularly with an increasing aging population. The discovery of epidermal stem cells in the HF has given new life to the search for a cure for baldness. Drug discovery efforts are being increasingly centered on these stem cells, boosting the hair cycle and reversing miniaturization of HF. Better understanding of the molecular mechanisms underlying the immune attack in AA will yield new drugs. New discoveries in HF neogenesis and low-level light therapy will undoubtedly have a role to play. PMID:25662177

Androgenetic alopecia is a condition with a high prevalence worldwide and affects both males and females. Currently, only 2 approved treatments exist: finasteride (males only) and minoxidil 2 or 5% solution (males and females). We conducted a randomized, open-label, multicenter noninferiority study to determine whether a caffeine-based 0.2% topical liquid would be no less effective than minoxidil 5% solution in males (n = 210) with androgenetic alopecia. The primary end point was the percentage change in the proportion of anagen hairs from baseline to 6 months using a frontal and occipital trichogram. At 6 months, the group of the 5% minoxidil solution showed a mean improvement in anagen ratio of the trichogram of 11.68%, and the group of the 0.2% caffeine solution had an anagen improvement of 10.59%. The difference of mean values between both groups was 1.09%. The statistical analysis was performed and reported in accordance with the CONSORT Guidelines 2010 for reporting of noninferiority and equivalence randomized trials. A caffeine-based topical liquid should be considered as not inferior to minoxidil 5% solution in men with androgenetic alopecia. © 2017 The Author(s) Published by S. Karger AG, Basel.

Yamazaki, Masashi; Irisawa, Ryokichi; Tsuboi, Ryoji

2010-04-01

Temporal triangular alopecia (TTA) is a circumscribed, non-cicatricial form of alopecia confined to the frontotemporal region. The patient, a 15-year-old boy, was noticed at birth to have an alopecial area, sized 1.5 cm x 2.5 cm, in the right temporal region. Microscopic examination revealed miniaturized hair follicles accompanied by differentiated sebaceous glands. We have provided a synopsis of the past 52 cases. Of the 53 cases of TTA including our case, more than half (55.8%) were detected in childhood between the ages of 2 and 9 years, while 36.5% were detected at birth and only 3.8% (only two cases) in adulthood. There were three familial cases. Several congenital diseases were associated with the condition, for example, phakomatosis pigmentovascularis, Down syndrome and Dandy-Walker malformation. This information suggests that TTA can be recognized as a hamartomatous mosaic disease.

Radiesse is a soft tissue filler which has been widely used for cosmetic enhancement. The safety of Radiesse has been thoroughly investigated via numerous studies. A late-onset complication of Radiesse injection consists of foreign body granulomas, with only three case reports in over 10 years of clinical use. Herein, we describe the case of a patient who experienced alopecia with foreign body granulomas at the injection region one month after receiving a Radiesse injection. To our knowledge, this is the first report in the English literature of alopecia as an adverse event associated with Radiesse injection. The present case reminded physicians to evaluate more cautiously the necessity of injecting filler into hair-bearing area for lifting purpose. This procedure may cause foreign body granulomatous reaction, which may result in hair loss at the injection region.

Alopecia is a psychologically devastating complication of chemotherapy for which there is currently no effective therapy. PTH-CBD is a collagen-targeted parathyroid hormone analog that has shown promise as a therapy for alopecia disorders. This study compared the efficacy of prophylactic versus therapeutic administration of PTH-CBD in chemotherapy-induced alopecia using a mouse model that mimics the cyclic chemotherapy dosing used clinically. C57BL/6J mice were treated with a single subcutaneous injection of PTH-CBD (320 mcg/kg) or vehicle control before or after hair loss developing from three courses of cyclophosphamide chemotherapy (50-150 mg/kg/week). Mice receiving chemotherapy alone developed hair loss and depigmentation over 6-12 months. Mice pretreated with PTH-CBD did not develop these changes and maintained a normal-appearing coat. Mice treated with PTH-CBD after development of hair loss showed a partial recovery. Observations of hair loss were confirmed quantitatively by gray scale analysis. Histological examination showed that in mice receiving chemotherapy alone, there were small, dystrophic hair follicles mostly in the catagen phase. Mice receiving PTH-CBD before chemotherapy showed a mix of normal-appearing telogen and anagen hair follicles with no evidence of dystrophy. Mice receiving PTH-CBD therapy after chemotherapy showed intermediate histological features. PTH-CBD was effective in both the prevention and the treatment of chemotherapy-induced alopecia in mice, but pretreatment appears to result in a better cosmetic outcome. PTH-CBD shows promise as an agent in the prevention of this complication of chemotherapy and improving the quality of life for cancer patients.

We present six cases of frontal fibrosing alopecia, in which generalized hair loss is a feature. Although this variant of lichen planopilaris has been reported clinically in a number of patients, there is very little histological evidence that the condition exists in peripheral sites. We believe this pattern of involvement may be more common than is reported, and have provided histological evidence of lichen planopilaris being present at sites beyond the scalp and eyebrows.

Clinical Evidence of Increase in Hair Growth and Decrease in Hair Loss without Adverse Reactions Promoted by the Commercial Lotion ECOHAIR®.

Hair exerts protection, sensory functions, thermoregulation, and sexual attractiveness. Hair loss (alopecia) is caused by several diseases, drug intake, hormone imbalance, stress, and infections (Malassesia furfur). Drugs usually used in alopecia produce irreversible systemic and local side effects. An association of extracts of Coffea arabica and Larrea divaricata (ECOHAIR®) is successfully being commercialized in Argentina for hair growth. The aim of this study was to provide scientific support for the efficacy and innocuousness of ECOHAIR® in patients with noncicatricial alopecia during a 3-month treatment. The efficacy was determined through the assessment of an increase in hair volume, improvement in hair looks, growth of new hair, and a decrease in hair loss by the test of hair count and hair traction. The capacity to decrease the amount of dandruff was also evaluated as well as the adverse local effects caused by the treatment. ECOHAIR® spray improved the overall hair volume and appearance; it increased its thickness, induced hair growth, and decreased hair loss. Besides, no adverse local reactions were observed upon treatment with the product. This study provides scientific support for the clinical use of ECOHAIR® as a treatment to be used in noncicatricial alopecia. © 2017 S. Karger AG, Basel.

There are many laser technologies that are being tested that claim to support hair regrowth for patients with alopecia areata (AA). In this paper, we will determine whether the body of evidence supports the use of devices using monochromatic light sources to treat AA. Articles were gathered from PubMed, Embase, and the Cochrane database using these keywords: lasers, excimer laser, low-level laser therapy (LLLT), low-level light therapy, alopecia, alopecia areata, and hair loss with a category modifier of English. Ten clinical trials and seven case reports/abstracts were assessed. Eight clinical trials and two case reports demonstrated hair regrowth with the 308-nm excimer laser/light in men, women, and children. One case report demonstrated hair regrowth with the ALBA 355® laser. One clinical trial and two case reports demonstrated hair regrowth with LLLT. While two case reports demonstrated hair regrowth with fractional laser therapy, one clinical trial showed no improvement. The 308-nm excimer laser is a safe and effective treatment for men, women, and children with refractory AA of the scalp and beard. Larger, double-blinded clinical trials should be conducted to compare excimer laser therapy to standard treatments. More data is needed to determine the efficacy of LLLT and fractional laser therapy in the treatment of AA.

Hair loss (alopecia) from chemotherapy is one of the most feared side effects of many patients, particularly women. Many patients and their healthcare providers believe that cryotherapy can help prevent or mitigate these changes. Scalp cooling has been used for more than 30 years to prevent alopecia caused by chemotherapy, particularly taxanes and anthracyclines. This article presents an overview of the evidence for this strategy, as well as its impact on nursing care provision.

Reduced Coat 2 (Rco2) is an ENU-induced mutation affecting hair follicle morphogenesis by an abnormal and protracted catagen. We describe chromosomal mapping and molecular identification of the autosomal dominant Rco2 mutation. The Rco2 critical region on mouse chromosome 11 encompasses the alopecia loci, Bareskin (Bsk), Rex-denuded (Re(den)), Recombination induced mutation 3 (Rim3), and Defolliculated (Dfl). Recently, the gasdermin (Gsdm) gene was described as predominantly expressed in skin and gastric tissues. We provide evidence for a murine-specific gene cluster consisting of Gsdm and two closely related genes which we designate as Gsdm2 and Gsdm3. We show that Gsdm3 reflects a mutation hotspot and that Gsdm3 mutations cause alopecia in Rco2, Re(den), and Bsk mice. We infer a role of Gsdm3 during the catagen to telogen transition at the end of hair follicle morphogenesis and the formation of hair follicle-associated sebaceous glands.

To describe lipid-induced specific videokeratographic (VKG) corneal changes and subsequent resolution after eyelid washing. VKG was performed with C-Scan corneal topography. In all patients an excessive meibomian gland lipid secretion was found with or without coexistent chronic posterior blepharitis. After the initial VKG, a meticulous cleaning of the lids with a mild alkali shampoo (10% Johnson's baby shampoo in sterile water) was done, first by gently scrubbing the closed eyelid fissure with the solution to mobilize and emulsify any Meibomian gland secretions followed by cleaning of the upper and lower margins individually, using Q-tip applicators soaked in the detergent. Three patients with tear film lipid layer excess (TFLE), which correlated with the presence of a superior or central corneal steepening in VKG, were studied. In two of the subjects, careful lid washing reversed either completely or partially this VKG effect, whereas in the last patient the VKG changes after artificially increasing the tear film lipid content is described. Meibomian gland lipid secretions may induce mainly superior and occasionally central VKG corneal steepening that is not correlated with any slit-lamp pathologic findings. Computerized corneal topography can help detect such corneal abnormalities, and their reversibility may distinguish them from other pathologic conditions (such as contact lens-induced warpage, eccentric ablations, irregular astigmatism, superior keratoconus).

Color-dilution alopecia is a relatively uncommon hereditary skin disease seen in "Blue" and other color-diluted dogs. This syndrome is associated with a color-dilution gene. The initial clinical signs are the gradual onset of a dry, dull and poor hair coat quality. Hair shafts and hair regrowth are poor, and follicular papules may develop and progress to frank comedones. Hair loss and comedo formation are usually most severe on the trunk, especially color-diluted area on the skin. Six cases of color-dilution alopecia are reported in 3 months to 10 years old dogs. The breeds of dogs are blue Doberman Pinscher, Miniature Pinscher, Dachshund, and Schnauzer. Grossly, extensive partial hair loss was seen on the skin. Histopathologically, the epidermis is relatively normal but may be hyperplastic. Hair follicles are characterized by atrophy and distortion. Heavily clumped melanin is present in the epidermis, dermis and hair follicles.

Androgenetic alopecia (AGA) may affect up to 70% of men and 40% of women at some point in their lifetime. While men typically present with a distinctive alopecia pattern involving hairline recession and vertex balding, women normally exhibit a diffuse hair thinning over the top of their scalps. The treatment standard in dermatology clinics continues to be minoxidil and finasteride with hair transplantation as a surgical option. Here we briefly review current therapeutic options and treatments under active investigation. Dutasteride and ketoconazole are also employed for AGA, while prostaglandin analogues latanoprost and bimatoprost are being investigated for their hair growth promoting potential. Laser treatment products available for home use and from cosmetic clinics are becoming popular. In the future, new cell mediated treatment approaches may be available for AGA. While there are a number of potential treatment options, good clinical trial data proving hair growth efficacy is limited.

A 27-year-old male, who had developed diabetes mellitus type 1 (DMT1) since the age of eighteen and alopecia areata universalis nine months later, attended the outpatient clinics complaining of general fatigue and shortness of breath. A Schilling test was indicative of pernicious anemia. Antigastric parietal cell (AGPA) and anti-intrinsic factor antibodies were positive, confirming diagnosis of pernicious anemia. Thyroid and Addison's disease were excluded. Gastroscopy revealed atrophic gastritis without any evidence of carcinoid tumors. The aim of this case, which, to our knowledge, is the first one to describe a correlation between diabetes mellitus Type 1 (DMT1), pernicious anaemia, and alopecia areata universalis, is to remind the clinician of the increased risk of pernicious anaemia and gastric carcinoids in DMT1 patients. Screening for AGPA followed by serum gastrin and vitamin B(12) levels constitute the most evidence-based diagnostic approach.

Hair loss or alopecia affects the majority of the population at some time in their life, and increasingly, sufferers are demanding treatment. Three main types of alopecia (androgenic [AGA], areata [AA] and chemotherapy-induced [CIA]) are very different, and have their own laboratory models and separate drug-discovery efforts. In this article, the authors review the biology of hair, hair follicle (HF) cycling, stem cells and signaling pathways. AGA, due to dihydrotesterone, is treated by 5-α reductase inhibitors, androgen receptor blockers and ATP-sensitive potassium channel-openers. AA, which involves attack by CD8(+)NK group 2D-positive (NKG2D(+)) T cells, is treated with immunosuppressives, biologics and JAK inhibitors. Meanwhile, CIA is treated by apoptosis inhibitors, cytokines and topical immunotherapy. The desire to treat alopecia with an easy topical preparation is expected to grow with time, particularly with an increasing aging population. The discovery of epidermal stem cells in the HF has given new life to the search for a cure for baldness. Drug discovery efforts are being increasingly centered on these stem cells, boosting the hair cycle and reversing miniaturization of HF. Better understanding of the molecular mechanisms underlying the immune attack in AA will yield new drugs. New discoveries in HF neogenesis and low-level light therapy will undoubtedly have a role to play.

The use of low-level light therapy in the treatment of androgenetic alopecia and female pattern hair loss.

Gupta, Aditya K; Daigle, Deanne

Androgenetic alopecia (AGA) or female pattern hair loss (FPHL) is the most common form of hair loss in men and women. Despite its common occurrence, our understanding of the etiology of AGA and FPHL remains incomplete. As such, traditional therapies demonstrate modest efficacies and new therapies continue to be sought. Low-level light therapy (LLLT) is a relatively new technique used to promote hair growth in both men and women with AGA and FPHL. Currently, there exist several LLLT devices marketed for the treatment of alopecia, which claim to stimulate hair growth; yet marketing these devices only requires that safety, not efficacy, be established. A handful of studies have since investigated the efficacy of LLLT for alopecia with mixed results. These studies suffered from power, confounding and analysis issues which resulted in a high risk of bias in LLLT studies. Due to the paucity of well-conducted randomized controlled trials, the efficacy of LLLT devices remains unclear. Randomized controlled trials of LLLT conducted and reported according to the Consolidated Standards of Reporting Trials (CONSORT) statement would greatly increase the credibility of the evidence and clarify the ambiguity of the effectiveness of LLLT in the treatment of AGA and FPHL.

In treating androgenetic alopecia, 5% minoxidil is a commonly used topical drug. By using electrodynamic microneedle at the same time may increase absorption of minoxidil and further stimulate hair growth. A 24-week, randomized, evaluator blinded, comparative study was performed to evaluate the efficacy of treating Chinese male androgenetic alopecia using microneedle combined with 5% minoxidil topical solution. Randomized subjects received topical 5% minoxidil (group 1, n = 20), local electrodynamic microneedle treatments (group 2, n = 20), or local electrodynamic microneedle treatments plus topical 5% minoxidil (group 3, n = 20). A total of 12 microneedle treatments were performed every 2 weeks with 2ml 5% minoxidil delivery in group 3 during each microneedle treatment. Patient receiving topical 5% minoxidil applied 1 ml of the solution twice daily over the course of the study. A total of 60 Chinese male subjects with Norwood-Hamilton type III-VI androgenetic alopecia were treated. The mean improvement in total hair density from baseline to 24 weeks was 18.8/cm 2 in group 1, 23.4/cm 2 in group 2, and 38.3/cm 2 in group 3. The hair growth in the 3 groups was significantly different (P = 0.002), but there were no significant differences in toxicity found between the 3 groups. Treatment with microneedle plus topical 5% minoxidil was associated with the best hair growth.

Frontal fibrosing alopecia is a disease characterized by a symmetric and progressive loss of hair in the fronto-temporal and fronto-parietal lines that generally affects postmenopausal women. It is considered a variant of lichen planus pilaris for its clinical and histopathological features; although, its etiopathology is still unknown. In this report, we analyzed 4 cases of this disease and we discussed its clinical and histopathological characteristics, as well as their course after initiating treatment.

Temporal hair loss that results from traumatized hair follicles following rhytidectomy is an unsightly complication that can distress both the patient and the operating surgeon. Topical minoxidil is a proven therapy for androgenic alopecia and female senile alopecia. It has also been found to be useful in preventing the hair loss that commonly follows hair transplantation. To analyze through a retrospective study the effect of topical minoxidil on the incidence of temporal hair loss following facelift procedures. To our knowledge this is the first study to investigate the role of minoxidil in preventing post-rhytidectomy temporal alopecia. The charts of 60 women with a mean age of 58 years who underwent primary cervicofacial rhytidectomy were studied. Either a standard SMAS/flap technique or pliation was done in all cases. Each patient received either 2% or 5% topical minoxidil for 2 weeks before surgery and for 4 weeks after surgery, with a 5-day break period beginning on the day of surgery. Patients were monitored for complications immediately postoperatively and in 3-6 months of follow-up. Almost 80% of the patients underwent SMAS/flap procedures. Transient temporal alopecia was noted in only one patient, 6 weeks after discontinuing minoxidil. This resolved within 4 weeks of its reintroduction. The only other complications noted included minor hematomas (3.3%), skin slough/infection (1.7%), minor transient and localized edema (8.3%), minor ecchymosis (1.7%), a unilateral neuropraxia of the buccal nerve lasting 3 months (1.7%), and a minor temporary unilateral skin depression (1.7%). Side effects of minoxidil were not observed. On comparing our findings to results of larger rhytidectomy series in which minoxidil was not used prophylactically, and our experience before using minoxidil, we conclude that minoxidil plays a role in effectively preventing the temporal hair loss that occurs following primary cervicofacial rhytidectomies. We also found that minoxidil did not negatively impact on the risk of hematoma formation, skin necrosis, edema, or ecchymosis. Side effects of minoxidil did not present a problem.

2003-01-01

Recently a new entity, postmenopausal frontal fibrosing alopecia, was added to the established subtypes of scarring alopecias affecting postmenopausal women. This condition is characterized by a progressive frontal hairline recession associated with scarring. We studied the clinical and histopathologic features in four women with this disorder. Of note, a history of bilateral oophorectomy in two of them appears to be a new association. All four cases had frontoparietal recession of the hairline and two of them also had loss of their eyebrows. None of our four patients had any mucous membrane or other skin lesions. Histological examination showed perifollicular fibrosis and lymphocytic inflammation around the isthmus and infundibular areas of the follicles. No effective treatments have emerged for this type of postmenopausal alopecia, but progression of the hair loss and scarring appears to be self-limiting. We believe that this condition is a distinct clinicopathological variant of lichen planopilaris.

Central Centrifugal Cicatricial Alopecia: New Insights and a Call for Action.

2017-10-01

Central centrifugal cicatricial alopecia (CCCA) is a common and progressive form of lymphocyte predominant scarring alopecia which impacts negatively on the quality of life of those affected. It is seen more commonly in women of African descent with prevalence ranging from 2.7% to 5.7%. Current postulates include genetic inheritance, with traction inducing hairstyling practices and hair chemicals as aggravating factors. Histology reveals a perifollicular lymphocytic inflammation of the lower infundibulum, premature desquamation of the inner root sheath, and fibrous connective tissue. Treatment remains challenging and is directed at suppressing and preventing the inflammation, thus aborting scarring, with surgical intervention reserved for those who have stable disease or absence of histological inflammation. Future research with more patient numbers, focusing on the genetics of CCCA may prove useful in order to fully understand the etiology, thus providing more effective treatments for CCCA.

Alopecia areata is a rapid and complete loss of hair in one or several patches, usually on the scalp, affecting both males and females equally. It is thought to be an autoimmune disease which is treated with different modalities with variable success. Laser treatment of different wavelengths has been used in the management of this problem. To study the effect of the pulsed infrared diode laser (904 nm) in the treatment of alopecia areata.Methods. Sixteen patients with 34 resistant patches that had not responded to different treatment modalities for alopecia areata were enrolled in this study. In patients with multiple patches, one patch was left as a control for comparison. Patients were treated on a four-session basis, once a week, with a pulsed diode laser (904 nm) at a pulse rate of 40/s. A photograph was taken of each patient before and after treatment. The treated patients were 11 males (68.75%) and five females (31.25%). Their ages ranged between 4 and 50 years with a mean of 26.6+/-SD of +/-13.8, and the durations of their disease were between 12 months and 6 years with a mean of 13.43+/-SD of +/-18.34. Regrowth of hair was observed in 32 patches (94%), while only two patches (6%) failed to show any response. No regrowth of hair was observed in the control patches. The regrowth of hair appeared as terminal hair with its original color in 29 patches (90.6%), while three patches (9.4%) appeared as a white villous hair. In patients who showed response, the response was detected as early as 1 week after the first session in 24 patches (75%), while eight patients (25%) started to show response from the second session. The pulsed infrared diode laser is an effective mode of therapy with a high success rate for resistant patches of alopecia areata.

Finasteride at 1 mg/day and 5% topical minoxidil are effective in male androgenetic alopecia (MAGA). However, studies describing their effects in Chinese individuals are scarce. 450 Chinese MAGA patients were randomly assigned to receive finasteride (n = 160), minoxidil (n = 130) and combined medication (n = 160) for 12 months. The patients returned to the clinic every 3 months for efficacy evaluation. And efficacy was evaluated in 428 men at treatment end, including 154, 122, and 152 in the finasteride, 5% minoxidil, and combination groups, respectively. All groups showed similar baseline characteristics, including age at enrollment, and duration and severity of alopecia (p > 0.05). At 12 months, 80.5, 59, and 94.1% men treated with finasteride, 5% minoxidil and the combination therapy showed improvement, respectively. Adverse reactions were rare (finasteride, 1.8%; minoxidil, 6.1%), and disappeared right after drug withdrawal. In conclusion, finasteride is superior to 5% minoxidil, while the combined medication showed the best efficacy. © 2015 Wiley Periodicals, Inc.

Scalp cooling to prevent alopecia after chemotherapy can be considered safe in patients with breast cancer.

With modern scalp cooling equipment cytotoxic damage of hair root cells can be prevented in half of the patients with cancer at high risk of alopecia. However, traditionally doubt has existed whether scalp cooling might facilitate hiding and disseminating scalp skin metastases and thus decrease survival. We discuss this risk using frequency data on metastases in breast cancer from observational and autopsy studies and the Munich cancer registry. They showed the incidence of scalp skin metastases to be very low and not differ between scalp-cooled (0.04-1%) and non scalp-cooled (0.03-3%) patients with breast cancer and in need of chemotherapy. We found it rather unlikely that the incidence of scalp skin metastases might increase at all after scalp cooling, whereas a very small proportion of patients receiving chemotherapy are at risk to develop metastases at this site. Scalp cooling can thus safely be offered to patients treated with alopecia-inducing chemotherapy. Copyright © 2013 Elsevier Ltd. All rights reserved.

The role for 1,25-dihydroxyvitamin D3 and/or calcium in hair follicle cycling is not clear despite their impact on keratinocyte differentiation. We found that calbindin-D9k null (knockout) pups generated from calbindin-D9k knockout females fed a vitamin D-deficient, low-calcium (0.47%) diet develop transient alopecia. The pups appear phenotypically normal until 13 days of age, after which the hair progressively sheds in a caudocephalic direction, resulting in truncal alopecia totalis by 20-23 days, with spontaneous recovery by 28 days. Histological studies showed markedly dystrophic hair follicles, loss of hair shafts with increased apoptosis, and hyperplastic epidermis during this time. Ha1 expression is lost during catagen in all mice but recovers more slowly in the knockout pups on the vitamin D-deficient, low-calcium diet. Keratin 1 expression is reduced throughout days 19-28. The expressions of involucrin, loricrin, and cathepsin L is initially increased by day 19 but subsequently falls below those of controls by day 23, as does that of desmoglein 3. Feeding the mothers a high-vitamin D/high-calcium (2%)/lactose (20%) diet lessens the phenotype, and knockout pups fostered to mothers fed a normal diet do not develop alopecia. Our results show that in calbindin-D9k knockout pups, a maternal vitamin D-deficient/low-calcium diet leads to transient noncicatricial alopecia. Copyright © 2016 The Authors.

The psychological effect of alopecia areata (AA) is well documented, but group interaction may help lessen this burden. We aimed to determine factors that draw patients with AA and their families to group events. Surveys were administered at the annual alopecia areata bowling social in 2015 and 2016. This event is a unique opportunity for children with AA and their families to meet others with the disease and connect with local support group resources from the Minnesota branch of the National Alopecia Areata Foundation. Data from 2015 and 2016 were combined. Comparisons of subgroups were performed using Fisher exact tests for response frequencies and percentages and two-sample t tests for mean values. An equal number of men and women participated in the study (n = 13 each). The average age was 41.1 years. There were no significant differences (p > 0.05) in survey responses based on respondent age or sex. Twenty-three (88.5%) attendees sought to connect with others with AA and met three or more people during the event. Seventeen (65.4%) also attended other support group events. Twelve respondents (46.2%) came to support a friend or family member. One hundred percent of attendees identified socializing with others with AA as important. Group interaction is an important source of therapeutic support for people with AA and their families. © 2017 Wiley Periodicals, Inc.

Vitamin D-dependent rickets type II is a rare hereditary disorder. It occurs due to mutations in the gene chr. 12q12-q14, which codes for vitamin D receptor. End-organ resistance to 1,25-(OH) 2 vitamin D3 and alopecia in severe cases are the characteristic features. We report a case of a 4-year-old boy with loss of hair over the scalp and body - first observed after 1 month of birth. The boy also developed difficulty in walking at the age of 2 year. On analysis, reduced serum calcium level (7.5 mg/dL) and elevated alkaline phosphatase level (625 IU/L) were reported. Initially, the treatment included intramuscularly administered single dose of 600,000 IU vitamin D, followed by 400 IU of vitamin D along with 1 g of supplemental calcium every day. Periodic follow-up was conducted for 2 months. Improvement was observed in the biochemical parameters and X-rays of the distal radial and ulnar metaphyses, although no improvement was observed in alopecia.

Central centrifugal cicatricial alopecia: challenges and solutions

PubMed Central

Herskovitz, Ingrid; Miteva, Mariya

2016-01-01

Central centrifugal cicatricial alopecia (CCCA) is the most common scarring alopecia among African American women. Data about epidemiology, etiology, genetic inheritance, and management are scarce and come from individual reports or small series. CCCA has been associated with hot combing and traumatic hair styling for years; however, studies fail to confirm it as the sole etiologic factor. It has been shown in a small series that CCCA can be inherited in an autosomal dominant fashion, with a partial penetrance and a strong modifying effect of hairstyling and sex. CCCA presents clinically as a central area of progressive irreversible hair loss that expands to the periphery. A patchy form has also been described. Dermoscopy is helpful to identify the optimal site for the biopsy, which establishes the diagnosis. Well-designed randomized controlled trials are needed to discover the optimal management. At this point, patients are advised to avoid traction and chemical treatments; topical and intralesional steroids, calcineurin inhibitors, and minoxidil can be helpful in halting the progression.

The use of scalp cooling for the prevention of chemotherapy-induced alopecia (CIA) is increasing. Cold caps are placed onto the hair-bearing areas of the scalp for varying time periods before, during, and after cytotoxic chemotherapy. Although not yet reported, improper application procedures could result in adverse events (AEs). At present, there are no evidence-based scalp cooling protocols, and there is no regulatory oversight of their use. To report the occurrence of cold thermal injury (frostbite) on the scalp, following the use of cold caps for the prevention of CIA. We identified four patients who developed cold thermal injuries on the scalp following the application of cold caps. Medical records were analyzed to retrieve the demographic and clinical characteristics. The cold thermal injuries in our patients were grade 1/2 in severity and improved with topical interventions and interruption of cold cap use, although grade 1 persistent alopecia ensued in 3 patients. The true incidence of such injuries in this setting, however, remains unknown. Cold thermal injuries are likely infrequent and preventable AEs that may result from improper device application procedures during cold cap use. Although these untoward events are usually mild to moderate in severity, the potential occurrence of long-term sequelae (e.g., permanent alopecia and scarring) or the need to discontinue cold cap use, are not known. Prospective studies are needed to further elucidate the risk and standardize healthcare delivery methods, and to improve patient/supportive/healthcare provider education.

Thyroid hormone receptors are expressed in hair follicles and it is known that thyroid hormones can have a positive effect on hair growth, i.e. process which is disrupted in alopecia areata. The aim of this study was to determine the efficacy of topical triiodothyronine in patients with patchy alopecia areata. Ten patients with patchy alopecia areata were treated with triiodothyronine and placebo applied twice daily to either of two bilaterally symmetrical patches for 12 weeks. The two sides were randomly assigned following simple randomization procedure to one of the two treatment groups. The patients and the investigator were blinded to the content of the tubes. Hair regrowth was evaluated every 4 weeks. Blood samples for measurements of complete blood count along with thyroid function (T3, T4 and TSH) and liver function tests were taken at the baseline and at the end of study. After 12 weeks of treatment, there was no statistically significant difference between the outcome in terms of reduction of the patch size and hair regrowth. No adverse effects were noted. Triiodothyronine in the studied dosage and formulation was safe but not more effective than placebo. However, newer thyroid hormone analogues might be more effective and evaluating their effects probably warrants further consideration. © 2011 The Authors.

Minoxidil is effective in inducing hair growth in patients with androgenetic alopecia by stimulating hair follicles to undergo transition from early to late anagen phase. However, there have been no controlled studies of topical minoxidil in Asian women. The objective of this trial was to investigate the efficacy of 1% topical minoxidil for androgenetic alopecia in Japanese female patients using a double-blind controlled method. This trial included 280 Japanese female patients aged 20 years or older with androgenetic alopecia who were administered either 1% topical minoxidil (n = 140) or placebo (n = 140) for 24 weeks. The primary efficacy variable was mean change from baseline in non-vellus hair count/cm(2). The mean change was 8.15 in the 1% topical minoxidil group and 2.03 in the placebo group, with a significant difference between groups (p < 0.001) [difference: 6.12 (two-sided 95% confidence interval (CI): 3.29-8.96)]. Secondary variables included investigators' assessments and patients' self-assessments. As assessed by investigators, 29.2% (40/137) of the patients had moderate or better improvement in the 1% topical minoxidil group compared to 11.8% (16/136) in the placebo group (p < 0.001 versus placebo). The effect on hair growth was assessed as improved or better by 36.5% (50/137) of the patients themselves in the 1% topical minoxidil group compared to 23.5% (32/136) in the placebo group (p = 0.019 versus placebo). The patients tolerated treatment with 1% topical minoxidil well without significant adverse effects.

There is strong evidence that alopecia areata is of immunological background; Interleukin-17 (IL-17) is a Th17 pro-inflammatory cytokine that has been allied to the pathogenesis of different autoimmune and inflammatory diseases. This study aimed to measure serum IL-17A in patients with alopecia areata, and to study associations between IL-17A levels and disease severity before and after Narrowband-Ultraviolet B (NB-UVB), patient gender and age. Twenty patients with AA of the scalp were treated with (NB-UVB), and 15 healthy subjects' age and sex matched were enrolled as controls. Patients were assessed clinically by SALT score. Assay of serum levels of IL-17A by ELISA was done in patients and controls. The mean level of IL-17A was (15.63 Â ± 10.89 Pg/mL) in AA patient group, and (16.50 Â ± 5.02 Pg/mL) in control group. No statistically significant correlation was detected between SALT score and IL-17A level before (NB-UVB) treatment while a significant negative correlation between SALT score and IL-17A level was observed after treatment (r = -.448, P = .047). Mean SALT score for patients was (14.03 Â ± 13.48), and correlated positively with age (r = .446, P = .049). Although (NB-UVB) is an immune-modulatory type of treatment for alopecia areata of mild efficacy especially if it's used alone, it has shown significant decrease in serum IL-17A level among patients, and correlation to disease severity. © 2018 Wiley Periodicals, Inc.

Many therapeutic modalities have been used to treat alopecia areata, with variable efficacy and safety profiles. Unfortunately, none of these agents is curative or preventive. Also, many of these therapeutic agents have not been subjected to randomized, controlled trials, and, except for topical immunotherapy, there are few published studies on long-term outcomes. The treatment plan is designed according to the patient’s age and extent of disease. In this paper, the therapeutic agents are organized according to their efficacy and safety profiles into first-line, second-line, and third-line options. PMID:21833161

Introduction: Androgenetic alopecia (AGA) is one of the most common dermatologic disorders with a multifactorial etiology. Inflammatory activators such as Demodex infestation may play a role in the pathogenesis of some cases of androgenetic alopecia that do not respond to common treatments such as minoxidil and finasteride. The goal of this study is to evaluate the relationship between Demodex infestation and AGA. Materials and Methods: In this case-control study, 41 patients with AGA referred to the Dermatology Clinic of Imam Reza Hospital and 33 healthy individuals were evaluated as control. All of them were between 20 and 40 years old men. In order to identify Demodex infestation they were referred to the Parasitology laboratory. Results: Demodex was detected in 19.5% of patients and 15.2% of controls; therefore, there was no significant relationship between them statistically (P = 0.0787). Most of patients (85.4%) had greasy hair. The most common pattern of baldness was II degree in Hamilton scale. Conclusion: There is no relation between AGA and Demodex. PMID:19881989

Despite the current treatment options for different types of alopecia, there is a need for more effective management options. Recently, low-level laser therapy (LLLT) was evaluated for stimulating hair growth. Here, we reviewed the current evidence on the LLLT effects with an evidence-based approach, focusing more on randomized controlled studies by critically evaluating them. In order to investigate whether in individuals presenting with hair loss (male pattern hair loss (MPHL), female pattern hair loss (FPHL), alopecia areata (AA), and chemotherapy-induced alopecia (CIA)) LLLT is effective for hair regrowth, several databases including PubMed, Google Scholar, Medline, Embase, and Cochrane Database were searched using the following keywords: Alopecia, Hair loss, Hair growth, Low level laser therapy, Low level light therapy, Low energy laser irradiation, and Photobiomodulation. From the searches, 21 relevant studies were summarized in this review including 2 in vitro, 7 animal, and 12 clinical studies. Among clinical studies, only five were randomized controlled trials (RCTs), which evaluated LLLT effect on male and female pattern hair loss. The RCTs were critically appraised using the created checklist according to the Critical Appraisal for Therapy Articles Worksheet created by the Center of Evidence-Based Medicine, Oxford. The results demonstrated that all the performed RCTs have moderate to high quality of evidence. However, only one out of five studies performed intention-to-treat analysis, and only another study reported the method of randomization and subsequent concealment of allocation clearly; all other studies did not include this very important information in their reports. None of these studies reported the treatment effect of factors such as number needed to treat. Based on this review on all the available evidence about effect of LLLT in alopecia, we found that the FDA-cleared LLLT devices are both safe and effective in patients with MPHL and FPHL who did not respond or were not tolerant to standard treatments. Future randomized controlled trials of LLLT are strongly encouraged to be conducted and reported according to the Consolidated Standards of Reporting Trials (CONSORT) statement to facilitate analysis and comparison.

Background: To properly assess the progression and treatment response of alopecia, one must measure the changes in hair mass, which is influenced by both the density and diameter of hair. Unfortunately, a convenient device for hair mass evaluation had not been available to dermatologists until the recent introduction of the cross-section trichometer, which directly measures the cross-sectional area of an isolated bundle of hair. Objective: We sought to evaluate the accuracy and sensitivity of the HairCheck® device, a commercial product derived from the original cross-section trichometer. Materials and Methods: Bundles of surgical silk and human hair were used to evaluate the ability of the HairCheck® device to detect and measure small changes in the number and diameter of strands, and bundle weight. Results: Strong correlations were observed between the bundle's cross-sectional area, displayed as the numeric Hair Mass Index (HMI), the number of strands, the silk/hair diameter, and the bundle dry weight. Conclusion: HMI strongly correlated with the number and diameter of silk/hair, and the weight of the bundle, suggesting that it can serve as a valid indicator of hair mass. We have given the name cross-section trichometry (CST) to the methodology of obtaining the HMI using the HairCheck® system. CST is a simple modality for the quantification of hair mass, and may be used as a convenient and useful tool to clinically assess changes in hair mass caused by thinning, shedding, breakage, or growth in males and females with progressive alopecia or those receiving alopecia treatment.

INTRODUCTION The use of scalp cooling for the prevention of chemotherapy-induced alopecia (CIA) is increasing. Cold caps are placed onto the hair-bearing areas of the scalp for varying time periods before, during, and after cytotoxic chemotherapy cycles. Although not yet reported, improper application procedures could result in undesirable adverse events (AEs). At present, there are no evidence-based scalp cooling protocols, and there is no regulatory oversight of their use. OBJECTIVE To report the occurrence of cold thermal injury (frostbite) on the scalp, following the use of cold caps for the prevention of CIA. MATERIALS AND METHODS We identified four patients who developed cold thermal injuries on the scalp following the application of cold caps. Medical records were analyzed to retrieve the demographic, clinical, and histologic characteristics. RESULTS The cold thermal injuries in our patients were grade 1/2 in severity and improved with topical interventions, although mild persistent alopecia ensued in 3 patients. The true incidence of such injuries in this setting however, remains unknown. CONCLUSIONS Cold thermal cold injuries are likely an infrequent and preventable AE that may result from improper device application procedures during scalp cooling. Although these untoward events are usually mild to moderate in severity, the potential occurrence of long-term sequelae (e.g. permanent alopecia, scarring) are not known. Future prospective studies are needed to further elucidate the risk and standardized delivery methods, and patient/clinical education. PMID:27146710

Chronic arsenic poisoning is an important public health problem and most notable in West Bengal and Bangladesh. In this study different systemic manifestations in chronic arsenic poisoning were evaluated. A nonrandomized, controlled, cross-sectional, observational study was carried out in Arsenic Clinic, Institute of Postgraduate Medical Education and Research, Kolkata, West Bengal, over a period of 1 year 4 months. Seventy-three cases diagnosed clinically, consuming water containing arsenic ≥50 μg/L and having hair and nail arsenic level >0.6 μg/L, were included. Special investigations included routine parameters and organ-specific tests. Arsenic levels in the drinking water, hair, and nail were measured in all. Twenty-five nonsmoker healthy controls were evaluated. Murshidabad and districts adjacent to Kolkata, West Bengal, were mostly affected. Middle-aged males were the common sufferers. Skin involvement was the commonest manifestation (100%), followed by hepatomegaly [23 (31.5%)] with or without transaminitis [7 (9.58%)]/portal hypertension [9 (12.33%)]. Restrictive abnormality in spirometry [11 (15.06%)], bronchiectasis [4 (5.47%)], interstitial fibrosis [2 (2.73%)], bronchogenic carcinoma [2 (2.73%)], oromucosal plaque [7 (9.58%)], nail hypertrophy [10 (13.69%)], alopecia [8 (10.95%)], neuropathy [5 (6.84%)], and Electrocardiography abnormalities [5 (6.84%)] were also observed. Mucocutaneous and nail lesions, hepatomegaly, and restrictive change in spirometry were the common and significant findings. Other manifestations were characteristic but insignificant.

Histologic features of alopecias: part II: scarring alopecias.

The diagnosis of disorders of the hair and scalp can generally be made on clinical grounds, but clinical signs are not always diagnostic and in some cases more invasive techniques, such as a biopsy, may be necessary. This 2-part article is a detailed review of the histologic features of the main types of alopecia based on the traditional classification of these disorders into 2 major groups: scarring and nonscarring alopecias. Scarring alopecias are disorders in which the hair follicle is replaced by fibrous scar tissue, a process that leads to permanent hair loss. In nonscarring alopecias, the follicles are preserved and hair growth can resume when the cause of the problem is eliminated. In the second part of this review, we describe the histologic features of the main forms of scarring alopecia. Since a close clinical-pathological correlation is essential for making a correct histopathologic diagnosis of alopecia, we also include a brief description of the clinical features of the principal forms of this disorder.

Chemotherapy for breast cancer induces alopecia, representing a major source of patient distress. This study assesses whether a scalp-cooling device is effective in reducing chemotherapy-induced alopecia, and assesses adverse treatment effects. A prospective observational study including women with breast cancer undergoing chemotherapy and scalp cooling using a Paxman device. The primary efficacy end points were: successful hair preservation (no hair loss; <30% hair loss not requiring a wig; or <50% hair loss not requiring a wig) at the completion of chemotherapy. Secondary end points included adverse effects such as headache, pain, nausea or dizziness. The study enrolled 131 participants. Mean patient age was 49.8 years; 74% received anthracycline/taxane-based chemotherapy and 26% received taxane-monotherapy based chemotherapy. Hair preservation was successful in 102 women who underwent scalp cooling (71.0%; 95% CI = 63-79%). Only adverse events related to device use were collected, representing 7% (95% CI = 3-11%) of cases. Scalp cooling is effective in preventing hair loss among breast cancer patients undergoing standard chemotherapy treatment, and has minimal adverse effects. Copyright © 2018.

Meibomian gland disease is generally accepted as the leading cause for evaporative dry eye disease (DED). In a previous study, perfluorohexyloctane, a semifluorinated alkane, has been demonstrated to significantly increase tear film breakup time and to reduce corneal fluorescein staining in patients with evaporative DED, thereby vastly reducing dry eye-related symptoms. This study was set up to evaluate perfluorohexyloctane in a larger population of patients with Meibomian gland dysfunction. Seventy-two patients with Meibomian gland disease and associated dry eye received 1 drop of perfluorohexyloctane 4 times daily during an observational, prospective, multicenter, 6-8-week study. Clinical assessment included best-corrected visual acuity, intraocular pressure, Schirmer test I, tear film breakup time, anterior and posterior blepharitis assessment, number of expressible Meibomian glands, meibum quality and quantity, ocular surface fluorescein staining, lid margin and symptom assessment, and Ocular Surface Disease Index (OSDI © ). From the 72 patients recruited, 61 completed the trial per protocol. Nine patients did not apply the medication as recommended and 2 patients were lost to follow-up. Tear film breakup time, corneal and conjunctival fluorescein staining, number of expressible Meibomian glands, and severity of anterior and posterior blepharitis significantly improved after 6-8 weeks of perfluorohexyloctane application. In addition, symptoms improved as demonstrated by a significant decrease of OSDI-values from 37 (±13) to 26 (±16). In concordance with previous findings, 6-8 weeks of topical application of perfluorohexyloctane significantly improves clinical signs of Meibomian gland disease and associated mild to moderate DED.

A blue roan Percheron foal was born with poorly circumscribed patchy alopecia of the trunk and legs. Teeth and hoof development were normal. Alopecia was progressive, becoming almost complete by 1 year of age. Histopathological findings in a skin biopsy obtained at 7 months of age were consistent with severe follicular hypoplasia. Sebaceous glands, epitrichial sweat glands and arrector pilae muscles were normal. The horse is alive and otherwise well at 6 years of age, although adult stature is considered small for this breed. The clinical history and histopathological findings are most consistent with a form of congenital hypotrichosis.

The lack of data on the process of alopecia in women suffering from diabetes mellitus made us undertake research in this area. The aim of this paper was the assessment of the state of head hair in trichological and clinical examinations, and on the basis of questionnaire. 50 women (age 44-82 years) were included in the study. Alopecia in women with diabetes mellitus is diffuse, located on the apex of the head and basic hair loss lies in telogenic pathomechanism. The highest percentage of telogenic hair is found in women treated with biguanides, and the lowest one in female patients taking insulin.

A four-year-old, entire male toy poodle was presented with a two-and-a-half-week history of ocular discharge progressing to periorbital alopecia, depigmentation, alopecia and ulceration around the muzzle. There was also a haemorrhagic discharge from the ears, pyrexia, lethargy and generalised lymphadenopathy. The clinical, cytological, bacteriological and histopathological findings were consistent with a diagnosis of dermatitis resembling juvenile cellulitis in an adult dog. Glucocorticoid therapy led to rapid resolution of the clinical signs and the dog has remained in remission for two years after cessation of treatment.

Dermatologic manifestations of endocrine disorders

The skin serves as a window for clinicians to understand, diagnose, and monitor endocrine disease. Dermatologic manifestations of endocrinopathies contribute significantly to an individual’s health and quality of life. In this review, we outline various disorders of the hypothalamic-pituitary axis, thyroid gland, pancreas, adrenal gland, and androgen axis as well as hereditary endocrine syndromes. In acromegaly, glycosaminoglycan deposition contributes to a thickening of skin and soft tissue, which manifests as coarsening and enlargement of facial and acral structures. Stimulation of the thyrotropin receptor in hyperthyroidism results in mesenchymal tissue proliferation and consequent pretibial myxedema; other associated cutaneous features include onycholysis, and hyperhidrosis. Individuals with hypothyroidism exhibit cold, dry skin and brittle hair as well as a jaundice-like appearance due to carotene excess. The cutaneous features of diabetes mellitus (DM), mediated to a large extent by hyperglycemia and hyperinsulinemia, include necrobiosis lipoidica diabeticorum (NLD), diabetic dermopathy, and acanthosis nigricans. Pediatric patients with Cushing’s syndrome almost invariably present with truncal obesity and growth retardation; disruption of collagen formation and the catabolic effects of hypercortisolism result in skin atrophy and purple abdominal striae. In patients with Addison’s disease, generalized hyperpigmentation, secondary to elevated levels of melanocyte-stimulating hormone (MSH), is most prominent in sun-exposed areas. Due to hyperandrogenism, individuals with polycystic ovarian syndrome (PCOS) often exhibit hirsutism, acne vulgaris, and androgenetic alopecia. In multiple endocrine neoplasia (MEN) syndromes, specific gene mutations may lead to angiofibromas, lichen amyloidosis, and ganglioneuromas. Disruptions of immune regulation result in autoimmune polyglandular syndromes (APS) and associated clinical features including chronic mucocutaneous candidiasis, vitiligo, and alopecia areata. This paper highlights the underlying pathophysiology, dermatologic manifestations, and treatment of the aforementioned endocrine disorders. PMID:29184811

The course of time itself in alive organisms is treated from positions of the special theory of the relativity created by A. Einstein in 1905 and added by the Nobel winners H.A.Lorentsem, M. Plankom, M. fon Laue. These achievements of fundamental physics have been put in a basis of special medical technology "Resonant chronophytotherapy" (SMT RCPT) which is applied in practice of treatment of chronic diseases for 27 years. Grass tinctures in various dosages are used in SMT RCPT, which patients take once a day during precisely designated time. Parameters "dosage-time" daily vary. SMT RCPT have been conducted in treatment of epilepsy bronchial asthma, rheumatism, sclerodermia, hypertension, chronic glomerulonephritis, vegeto-vascular dystonia, female sterility, circular alopecia, vitiligo, eczema, psoriasis, onychomycosis. SMT RCPT does have adverse events, has no contra-indications to its use, directed, first of all, on elimination of nonspecific signs of a disease, reduces dependence and complications of the use of chemical synthetic preparations. SMT RCPT can be combined with any kind of specific treatment. Internet-variant of SMT RCPT has been developed. Chronomedicine is priority tendency in industrialized countries of the world--the USA, the Great Britain, Germany, France, Russia, China, Japan and appears on lead positions among alternative methods of treatment, both traditional, and non-traditional.

Several studies have demonstrated an association between androgenetic alopecia (AGA) and cardiovascular disease. Still controversies exist regarding the association. Are they truly associated? The purpose of the present study was to assess the prevalence of AGA and establish its association in young (<45 years) Asian Indian Gujarati male patients having coronary artery disease (CAD). Case-control prospective multicentric study was carried out on 424 men. Case group consisted of 212 male subjects having CAD (Group 1) and another 212, either sibling or first degree male relative of the case subjects (having no evidence of CAD) were considered as the control group (Group 2). Age, total cholesterol, incidence of diabetes mellitus, and hypertension were similar in both groups. The degree of alopecia was assessed using the Norwood-Hamilton scale for men. Statistical analysis was performed using Chi-square test. AGA was found in 80 (37.73%) young CAD patients (Group 1), whereas 44 (20.7%) of patients had alopecia in the control group (Group 2). There was statistically significant association between male AGA and CAD (P = 0.001). Odds ratio was 2.70 (95% confidence interval [CI], 1.72 ± 4.26). Statistically significant association was found between high grade baldness (Grades IV-VII) and CAD in young men (P < 0.05). Odds ratio = 2.36 (95% CI, 1.108 ± 5.033). There is statistically significant association of AGA in young Asian Gujarati male with CAD and the prevalence of AGA in young CAD patient is 37.73%. This study implies early onset AGA in male is independently associated with CAD, though mechanisms need to be investigated.

Contact immunotherapy with diphencyprone (DCP) is used to treat alopecia areata (AA). Its reported efficacy is variable, and individual response cannot be predicted. To identify patient and treatment course variables that may affect treatment outcome, and to review DCP service to identify potential areas for development and improvement. This was a retrospective review of a DCP service over a 20-year period (1991-2010). Complete data was available for 205 treatment courses, and 162 (79%) treatment courses were completed for 133 patients. Overall, 72.2% (96/133) of patients had some hair regrowth (any grade). In 15.8% of cases (21/133), response was > 90% regrowth. However, 27.1% (36/133) had no response. We found that extent of alopecia at baseline and duration of disease were statistically significant when comparing patients with an optimal outcome to those without (P < 0.05). In contrast to other reports, atopy, age at onset and nail dystrophy were not statistically significant. For patients receiving more than one course, response to DCP treatment was broadly consistent. Extent of alopecia at baseline and duration of disease are important factors in predicting response. Our results suggest that atopy should not be considered a predictor of poor outcome with respect to DCP treatment. A need for improved data collection, particularly regarding longer-term outcomes, was identified. The role of maintenance therapy requires objective assessment. Opportunities for DCP self-administration by patients should be explored. Limitations of this study include the retrospective nature of the review and lack of long-term follow-up data. © 2015 British Association of Dermatologists.

According to the hypothesis on the stimulating effect of adenosine on increasing fibroblast growth factor 7 in dermal papilla cells and its vasorelaxant effect, we performed this study to compare the effect of topical minoxidil 5% and adenosine 0.75% on male pattern androgenetic alopecia. This prospective-randomized study recruited 110 male patients suffering from grade II-V Hamilton androgenetic alopecia. Fifty-five patients received minoxidil 5% (group 1) and adenosine 0.75% (group 2) each. Later, 16 patients were excluded due to allergic reactions or loss to follow up. After 3 and 6 months of treatment, complete and relative recovery rates alongside patient satisfaction rate (faster prevention of primary hair loss and appearance of newly grown hair) were compared between the groups. After 3 months of treatment, relative recovery was achieved in 2.4% and 1.9% of patients in group 1 and group 2, respectively, which was not significantly different (p=0.17). During 6 months, the relative recovery rate did not change either within or between the groups (p=0.99) and after 6 months none of the patients achieved complete recovery. However, the patient satisfaction rate was significantly higher in group 2 (p=0.003). In the light of the results, adenosine has no statistically superiority to minoxidil in the treatment of androgenetic alopecia according to recovery rates. However, the patients were significantly more satisfied with adenosine because of faster prevention of hair loss and appearance of the newly grown hairs. It seems further studies with larger sample size or different drug dosages are required to clarify the findings.

Flutamide is a potent anti-androgen with the several unwanted side effects in systemic administration, therefore, it has attracted special interest in the development of topically applied formulations for the treatment of androgenic alopecia. The purpose of this study was to prepare and characterize the solid lipid nanoparticles (SLNs) of Flutamide for follicular targeting in the treatment of the androgenic alopecia. Flutamide-loaded SLNs, promising drug carriers for topical application were prepared by hot melt homogenization method. Drug permeation and accumulation in the exercised rat skin and histological study on the male hamsters were performed to assess drug delivery efficiency in vitro and in vivo, respectively. The optimized Flutamide-loaded SLNs (size 198 nm, encapsulation efficiency percentage 65% and loading efficiency percentage 3.27%) exhibited a good stability during the period of at least 2 months. The results of X-ray diffraction showed Flutamide amorphous state confirming uniform drug dispersion in the SLNs structure. Higher skin drug deposition (1.75 times) of SLN formulation compared to Flutamide hydroalcoholic solution represented better localization of the drug in the skin. The in vivo studies showed more new hair follicle growth by utilizing Flutamide-loaded SLNs than Flutamide hydroalcoholic solution which could be due to the higher accumulation of SLNs in the hair follicles as well as slowly and continues release of the Flutamide through the SLNs maximizing hair follicle exposure by antiandrogenic drug. It was concluded Flutamide-loaded SLN formulation can be used as a promising colloidal drug carriers for topical administration of Flutamide in the treatment of androgenic alopecia.

Alopecia is a dermatological condition for which Janus kinase (JAK) inhibitors have recently emerged as potential therapy options, but with limited practical use because of the systemic side effects. The topical use of Ruxolitinib in alopecia universalis has been demonstrated, but little is known about the pharmacodynamics and pharmacokinetics of this way of administration. Nanomedicine provides improved therapeutics. In the current paper we present preliminary data regarding the potential use of Ruxolitinib-conjugated gold nanoparticles (GNPs) in dermatological conditions, as GNPs have been proven to have a reduced absorption rate into the systemic blood flow for cutaneous administration. Internalization of the newly formed bioconjugate was assessed by electron microscopy and the functional effects of the drug were investigated by cell counting, flow cytometry and western blotting. Our data show that gold nanoparticles conjugated with Ruxolitinib inhibit the proliferation of fibroblasts by inhibiting JAK2 protein. Ruxolitinib carried by gold nanoparticles alters the proliferation of human fibroblasts, which is of great clinical importance as it can be readily administered on the skin with minimal risk of systemic side effects.

Delaney, Sean W; Zhang, Paul

2017-12-29

Alopecia is a common disorder affecting over half of the world's population. Within this condition, androgenic alopecia (AA) is the most common type, affecting 50% of males over 40 and 75% of females over 65. Anecdotal paradoxical hypertrichosis noted during laser epilation has generated interest in the possibility of using laser to stimulate hair growth. In this study, we aimed to critically appraise the application of low-level laser therapy for the treatment of AA in adults. A systematic review was performed on studies identified on Medline, EMBASE, Cochrane database, and clinicaltrials.org. Double-blinded randomized controlled trials were selected and analyzed quantitatively (meta-analysis) and qualitatively (quality of evidence, risk of bias). Low-level laser therapy appears to be a promising noninvasive treatment for AA in adults that is safe for self-administration in the home setting. Although shown to effectively stimulate hair growth when compared to sham devices, these results must be interpreted with caution. Further studies with larger samples, longer follow-up, and independent funding sources are necessary to determine the clinical effectiveness of this novel therapy.

Tofacitinib (formerly known as CP-690,550, CP690550, tasocitinib), a novel selective immunosuppressant, is a small molecule classified as Janus kinase inhibitor. The aim of this review article is to present updated data summary on the tofacitinib in the field of dermatology. We undertook a structured search of bibliographic databases for peer-reviewed scientific articles, including review articles, original research articles as well as case report articles based on inclusion/exclusion criteria. Technical reports on tofacitinib from U.S. Food and Drug Administration and European Medical Agency were also included. Forty-three papers were included in this review. We report current data on tofacitinib chemical properties, pharmacology, non-clinical toxicity, as well as efficacy and safety in potential new indications in dermatology: psoriasis, alopecia areata, vitiligo, atopic dermatitis and nail dystrophy associated with alopecia areata. JAK/STAT pathway has an important role in the pathogenesis of psoriasis, alopecia areata, atopic dermatitis, and vitiligo. Despite encouraging efficacy, due to concerns about the overall safety profile of tofacitinib, additional studies will have to determine the adequate risk-to-benefit ratio.

Alopecia areata (AA) is one of the most common causes of localized hair loss. There is no universally proven therapy that induces and sustains remission of hair growth in AA. To compare the efficacy and safety of topical latanoprost, minoxidil and betamethasone valerate on hair growth in patients with AA. Hundred patients with AA classified into five groups of 20 treated with: Group I, latanoprost 0.1% lotion; Group II, minoxidil 5% lotion; Group III, betamethasone valerate 0.1% solution; Group IV, combination of latanoprost lotion and betamethasone valerate solution and Group V, a vehicle lotion control group. There was a statistically significant improvement in all therapeutic groups when compared with control group and reduction of severity of alopecia tool score of scalp and beard before and after treatment for all therapeutic groups. Latanoprost, minoxidil and betamethasone valerate are effective and safe in the treatment of patchy AA. The use of latanoprost added to the therapeutic efficacy of topical betamethasone valerate in the treatment of AA and could be an effective adjunctive topical therapy for AA.

Transepidermal drug delivery (TED) is a new potential method in dermatology. Permeability alterations induced by ablative fractional resurfacing have been described with the aim to increasing the delivery of different substances into the skin. To evaluate clinical response and side effects of TED in areata alopecia (AA) treatment using ablative fractional methods associated with acoustic pressure ultrasound (US) to deliver triamcinolone solution into the skin. Five cases of AA underwent treatment which comprised of 3 steps: 1) Ablative fractioned RF or CO2 laser 2) topical application of triamcinolone 3) acoustic pressure wave US. The number of sessions varied according to the clinical response, ranging from one to six sessions. All patients had complete recovery of the area treated. Two of them treated with ablative fractional RF + triamcinolone + US had complete response after three and six sessions. The other two treated with ablative fractional CO2 + triamcinolone + US had complete response after one session. Fractioned ablative resurfacing associated with acoustic pressure wave US is a new option to areata alopecia treatment with good clinical result and low incidence of side effects.

There are no reliably effective therapies for alopecia areata (AA). We sought to evaluate the benefit and adverse effects of the Janus kinase 1/3 inhibitor, tofacitinib, in a series of adolescent patients with AA. We reviewed the records of 13 adolescent patients with AA treated with tofacitinib. Severity of disease was assessed using the Severity of Alopecia Tool (SALT). Adverse events were evaluated by laboratory monitoring, physical examinations, and review of systems. Thirteen patients, aged 12 to 17 years, with AA were treated with tofacitinib. Nine patients experienced clinically significant hair regrowth. Median percent change in SALT score was 93% (mean 61%; 1%-100%) at an average of 6.5 months of treatment. Adverse events were mild. Limitations include the retrospective nature of the data, small sample size, and lack of a control group. Tofacitinib is a promising therapy for AA in adolescents. The use of tofacitinib and other Janus kinase inhibitors for the treatment of AA in this age group should be further evaluated in prospective clinical trials.

Lymphocytic Mural Folliculitis Resembling Epitheliotropic Lymphoma in Tigers ( Panthera tigris).

PubMed

Sula, Mee-Ja M; Frank, Linda A; Ramsay, Edward C

2018-01-01

A striking form of lymphocytic mural folliculitis is described in 6 tigers ( Panthera tigris). Clinically, all tigers exhibited regionally extensive chronic, variably waxing and waning alopecia with minimal scaling and crusting most pronounced over the head, neck, and shoulders. More severely affected tigers exhibited marked hyperpigmentation and lichenification. Pruritus was not a feature. Tigers generally lacked signs of systemic illness and clinical pathology findings were unremarkable. Histologic examination of skin biopsies revealed infiltrative lymphocytic mural folliculitis extending the length of the hair follicle. Mild epidermal lymphocytic infiltrates were frequent. The surrounding dermis was histologically unremarkable in 4 of 6 tigers or associated with mild perifollicular and periadnexal mixed inflammation in 2 of 6 tigers. The cause of the mural folliculitis was not identified, and tigers responded poorly to immunomodulatory therapy. Lymphocytic mural folliculitis might be a nonspecific hypersensitivity reaction pattern in tigers, and care should be taken to differentiate this reaction pattern from epitheliotropic T-cell lymphoma.

2017-04-01

INTRODUCTION: Central centrifugal cicatricial alopecia (CCCA) is a form of scarring alopecia primarily affecting women of African descent on the crown of the scalp. Limited data exists regarding evidence-based treatment for CCCA.

OBJECTIVE: To examine photos of subjects with CCCA before and after treatment in order to evaluate results of treatment and compare results of different treatment regimens.

METHODS: Photographs of 15 subjects with CCCA before and after treatment were evaluated by two blinded investigators who assigned disease severity scores to photographs based on a published scale: Central Scalp Alopecia Photographic Scale in African American Women.

RESUTLS: Median change in severity score (post-treatment severity score - pre-treatment severity score) was 0.5 (P = 0.58) for all 15 subjects receiving a series of 7 to 8 intralesional steroid injections along with topical steroids (Class I/II) +/- minoxidil and +/- anti-dandruff shampoo, indicating worsening of disease after treatment. Subjects receiving minoxidil versus those who did not (0.25 vs 0.5; P = 0.38) and subjects receiving anti-dandruff shampoo versus those who did not (0.0 vs 0.5; P = 0.42) demonstrated no statistically significant difference in pre- and post-treatment severity scores. Of 15 subjects, 5/15 (33.3%) had decreased severity scores, 8/15 (53.3%) had increased severity scores, and 2/15 (13.3%) had no change in severity scores.

CONCLUSIONS: Although no statistically significant difference was found in pre- versus post-treatment disease severity, this may indicate intralesional steroid injections and topical steroids +/- minoxidil and +/- anti-dandruff shampoo halt disease progression.

2015-01-01

The influence of systemic comorbidities on the success of scalp cooling during chemotherapy (CT) is widely unexplored. Comorbidities often require additional medication which itself can occasionally cause alopecia. This study investigates the influence of selected parameters on the efficacy of scalp cooling for the prevention of CT-induced alopecia. 226 cancer patients were treated with various CT regimens in combination with sensor-controlled scalp cooling. 136 breast cancer patients received (neo)adjuvant therapy, and 76 of these patients received epirubicine and cyclophosphamide (4× EC 3w) followed by paclitaxel (12× T w). The following parameters were prospectively investigated: chemotherapy-induced alopecia, systemic comorbidities and co-medication, nicotine abuse, hair treatment, menopausal status, and trichologic status. Scalp cooling was successful (no or not visible hair loss; common toxicity criteria 0-1) in 65% of all patients, in 65% of the 136 breast cancer patients, and in 68% of the 76 patients receiving EC/T. In this subgroup, premenopausal patients (p = 0.009) and those without systemic comorbidities (p = 0.003), without co-medication (p < 0.001) and with high hair density (p = 0.038) showed less hair loss during CT; an effect was also seen for nicotine abuse (p = 0.023). Hair length and hair treatment had no significant influence. Sensor-controlled scalp cooling represents an effective addition to supportive cancer therapy. The success of scalp cooling depends on the applied CT regimen. Parameters like menopausal status, systemic comorbidities, medication, nicotine abuse, and original hair density also influence the outcome of hair loss prevention. © 2015 S. Karger GmbH, Freiburg.

Objective: The purpose of the present study was to assess the prevalence of AGA and establish its association in young (<45 years) Asian Indian Gujarati male patients having coronary artery disease (CAD). Materials and Methods: Case-control prospective multicentric study was carried out on 424 men. Case group consisted of 212 male subjects having CAD (Group 1) and another 212, either sibling or first degree male relative of the case subjects (having no evidence of CAD) were considered as the control group (Group 2). Age, total cholesterol, incidence of diabetes mellitus, and hypertension were similar in both groups. The degree of alopecia was assessed using the Norwood-Hamilton scale for men. Statistical analysis was performed using Chi-square test. Results: AGA was found in 80 (37.73%) young CAD patients (Group 1), whereas 44 (20.7%) of patients had alopecia in the control group (Group 2). There was statistically significant association between male AGA and CAD (P = 0.001). Odds ratio was 2.70 (95% confidence interval [CI], 1.72 ± 4.26). Statistically significant association was found between high grade baldness (Grades IV-VII) and CAD in young men (P < 0.05). Odds ratio = 2.36 (95% CI, 1.108 ± 5.033). There is statistically significant association of AGA in young Asian Gujarati male with CAD and the prevalence of AGA in young CAD patient is 37.73%. Conclusion: This study implies early onset AGA in male is independently associated with CAD, though mechanisms need to be investigated. PMID:25114445

Latanoprost is a prostaglandin analogue used to treat glaucoma. It can cause adverse effects, such as iridial and periocular hyperpigmentation, and eyelash changes including pigmentation and increased thickness, length, and number. Latanoprost has been used to treat eyelash alopecia, but knowledge on its effects on human scalp hair growth is not available. The primary objectives were to assess the efficacy of latanoprost on hair growth and pigmentation. The secondary objectives were to assess the effect on scalp pigmentation; investigate the treatment duration needed to affect hair growth, hair pigmentation, and scalp pigmentation; and assess safety of latanoprost. Sixteen men with mild androgenetic alopecia (Hamilton II-III) were included. Latanoprost 0.1% and placebo were applied daily for 24 weeks on two minizones on the scalp. Measurements on hair growth, density, diameter, pigmentation, and anagen/telogen ratio were performed throughout the study. At 24 weeks, an increased hair density on the latanoprost-treated site was observed compared with baseline (n = 16, P < .001) and placebo-treated site (P = .0004). Only young men with mild androgenetic alopecia were included. The results may not be applicable to other patient groups. Choice of investigational site may have affected the results. Latanoprost significantly increased hair density (terminal and vellus hairs) at 24 weeks compared with baseline and the placebo-treated area. Latanoprost could be useful in stimulating hair follicle activity and treating hair loss. Copyright © 2011 American Academy of Dermatology, Inc. Published by Mosby, Inc. All rights reserved.

Testicular leiomyosarcoma and marked alopecia in a cryptorchid ferret (Mustela putorius furo).

A 3.5-year-old male ferret, bought as male castrated, was presented to the veterinarian with marked alopecia of back, neck, abdomen and tail, a pronounced sexual behaviour and weight loss. An inguinal mass of about 2.5 cm in diameter was diagnosed as potentially tumorous inguinal testicle by ultrasound and fine-needle aspiration. Adrenal glands and prostate were ultrasonographically unremarkable. The surgically removed cryptorchid testicle contained a greyish tumour that was histologically composed of spindle-shaped cells with elongated nuclei, embedded in a fibro-vascular stroma. Up to two mitotic figures per high power field were noted. Additionally, an interstitial cell hyperplasia and marked reactive proliferation of a collagen-rich fibrous tissue were observed. Tumour cells were positive for α-smooth muscle actin, desmin, and occasionally vimentin and S-100, leading to the diagnosis of an intratesticular leiomyosarcoma. As an adrenal-associated endocrinopathy was excluded and a complete fur recovery was observed after removal of the cryptorchid testicle the alopecia was eventually due to hormones produced by the hyperplastic interstitial (Leydig) cells.

Alopecia areata.

Alopecia aerata (AA) is an autoimmune disease that presents as well defined patches of nonscarring hair loss with no overt epidermal changes. The life-time risk of AA in the general population is approximately 1.7%. As many as 60% of patients with AA have disease onset before 20 years of age. AA most commonly manifests as sudden loss of hair in well demarcated, localized area in the scalp. The hair loss is usually limited to a single patch. The lesion is usually round or oval. "Exclamation point hairs" are frequently seen at the periphery of the lesion. Because of the high rate of spontaneous recovery especially in those with small areas of hair loss or with a recent onset, not all patients require pharmacological treatment. A "watch-and-wait" approach is often recommended. Psychological support may be offered if necessary. For patients who actively desire treatment, topical corticosteroids and/or minoxidil are the treatment of choice. Interleukin (IL)-31 antibodies and 308-nm Excimer laser as novel treatment modalities appear promising in the armamentarium against this distressing disease. The review also outlined recent patents on the treatment of alopecia.

Zoster vaccine is recommended to reduce the incidence of herpes zoster and its complication of postherpetic neuralgia in older adults. However, there have been reports of autoimmune side effects post vaccination. We therefore aim to investigate the possible relationship of severe autoimmune adverse events (arthritis, vasculitis, systemic lupus erythematosus, thrombocytopenia, alopecia, Guillain-Barre syndrome, optic neuritis and multiple sclerosis) post zoster vaccination with a matched case-control study of reported events in the Vaccine Adverse Event Reporting System (VAERS). Our study showed no significantly increased risks of severe autoimmune adverse events, except arthritis and alopecia, after vaccination. Compared to the unexposed, patients with zoster vaccination had 2.2 and 2.7 times the odds of developing arthritis and alopecia, respectively (P<0.001 and P=0.015, respectively). However, almost none of these events was life threatening. Zoster vaccine is, therefore, relatively safe and unlikely to exacerbate or induce autoimmune diseases. Given its benefits and safety but low coverage, dermatologists and primary care physicians should encourage zoster vaccine use in elderly patients, including selected patients with autoimmune diseases.

Further Clinical Evidence for the Effect of IGF-1 on Hair Growth and Alopecia.

Observations on the Laron syndrome originally offered the opportunity to explore the effect of insulin-like growth factor 1 (IGF-1) deficiency on human hair growth and differentiation. According to its expression in the dermal hair papilla, IGF-1 is likely involved in reciprocal signaling. It has been shown to affect follicular proliferation, tissue remodeling, and the hair growth cycle, as well as follicular differentiation, identifying IGF-1 signaling as an important mitogenic and morphogenetic regulator in hair follicle biology. Of all the cytokines or growth factors that have been postulated to play a role in hair follicles, ultimately IGF-1 is known to be regulated by androgens. Accordingly, dermal papillary cells from balding scalp follicles were found to secrete significantly less IGF-1 than their counterparts from nonbalding scalp follicles. Herein, hypotrichosis in primary growth hormone deficiency, and a lack of response of female and male androgenetic-type alopecia to treatment with topical minoxidil and oral finasteride in patients who had undergone surgical resection of the pituitary gland, provide further evidence for an effect of IGF-1 on hair growth and alopecia.

Primary Follicular Dystrophy with Scarring Dermatitis in C57BL/6 Mouse Substrains Resembles Central Centrifugal Cicatricial Alopecia in Humans

A number of C57BL/6 (B6) substrains are commonly used by scientists for basic biomedical research. One of several B6 strain specific background diseases is focal alopecia that may resolve or progress to severe, ulcerative dermatitis. Clinical and progressive histologic changes of skin disease commonly observed in C57BL/6J and preliminary studies in other closely related substrains are presented. Lesions develop due to a primary follicular dystrophy with rupture of severely affected follicles leading to formation of secondary foreign body granulomas (trichogranulomas) in affected B6 substrains of mice. Histologically these changes resemble the human disease called central centrifugal cicatrical alopecia (CCCA). Four B6 substrains tested have a polymorphism in alcohol dehydrogenase 4 (Adh4) that reduces its activity and potentially affects removal of excess retinol. Using immunohistochemistry, differential expression of epithelial retinol dehydrogenase (DHRS9) was detected which may partially explain anecdotal reports of frequency differences between B6 substrains. The combination of these two defects have the potential to make high dietary vitamin A levels toxic in some B6 substrains while not affecting most other commonly used inbred strains. PMID:20861494

Histologic features of alopecias-part I: nonscarring alopecias.

2015-04-01

The diagnosis of disorders of the hair and scalp can generally be made on clinical grounds, but clinical signs are not always diagnostic and in some cases more invasive techniques, such as a biopsy, may be necessary. This 2-part article is a detailed review of the histologic features of the main types of alopecia based on the traditional classification of these disorders into 2 major groups: scarring and nonscarring alopecias. Scarring alopecias are disorders in which the hair follicle is replaced by fibrous scar tissue, a process that leads to permanent hair loss. In nonscarring alopecias, the follicles are preserved and hair growth can resume when the cause of the problem is eliminated. In the first part of this review, we describe the histologic features of the main forms of nonscarring alopecia. Since a close clinical-pathological correlation is essential for making a correct histologic diagnosis of alopecia, we also include a brief description of the clinical features of the principal forms of this disorder.

1993-01-01

Demodicosis was diagnosed in five black bears (Ursus americanus) from north-central Florida. The first bear examined, a 5-yr-old male, had severe alopecia except for the dorsal neck, paws, and ears. The skin was characterized by moderate orthokeratotic hyperkeratosis, and mild to moderate follicular hyperkeratosis. Superficial dermatitis, follicular pustules, and epidermal pustules were present, but rare. Specimens of Demodex sp. were seen most commonly within hair follicles devoid of hair and at the infundibulum of sebaceous glands. Four additional bears from the same area also had some degree of alopecia and skin scrapings were positive for Demodex sp. This mite may be common, although its prevalence is not known.

Satisfaction and convenience of using terpenoid-impregnated eyelid wipes and teaching method in people without blepharitis.

Demodex infestations cause blepharitis and are difficult to treat. Recently, a new type of eyelid wipes with terpenoids has been found effective. We aim to evaluate patient satisfaction after short-term use and compare two teaching modalities on the techniques of use. Eligible participants were taught to use eyelid wipes (Cliradex ® ) by either live or online video demonstration based on random allocation. Participants used the wipes twice daily for a week. All participants had prior evaluation of socioeconomic status, dry eye symptoms, and meibomian gland features. After 1 week, competence of use was assessed by participants showing their technique to the investigator, and a questionnaire on comfort, ease, and convenience of use was administered. Higher scores indicate greater satisfaction, and these levels are compared among the two teaching modalities using chi square. A total of 50 participants were recruited, with a mean age of 42±16 years, and 88% of the participants were females. Overall, median comfort level was 4.0 (range: 1-6), ease level was 5.0 (3-6), and convenience level was 5.0 (2-6). Median stinging was 2.0 (1-4), which corresponded to some but mild stinging. The median competence level was 4.0 (2-4), which corresponded to excellent competence. These satisfactory levels (ease, comfort, and convenience) experienced were not significantly associated with different socioeconomic indicators, that is, housing type, income, highest education level, and were not different between teaching methods ( p >0.05). Short-term use of Cliradex eyelid wipes seems to be acceptable to most people. The teaching instructions before using these wipes were equally effective - whether live or online video demonstration was used.

To report an unusual case of Demodex folliculitis presenting as periocular vesiculopustular rash. Case report. A 68 year-old woman presented with a unilateral periocular rash that was initially treated by her primary ophthalmologist with topical steroids and antivirals. Slit-lamp examination revealed severe bilateral blepharitis, right greater than left, with waxy sleeves around the eyelashes. The diagnosis of Demodex infestation was considered. Treatment with daily lid scrub with polyhexamethylene biguanide (PHMB), 1,2-hexanediol and 1,2-octanediol (OCuSOFT PLUS) and erythromycin ointment twice a day resulted in complete resolution of the symptoms after 4 weeks. Ophthalmologists should be aware of Demodex and consider it in the differential diagnosis of periocular skin lesions.

There are no epidemiological studies comparing the prevalence of skin diseases between civilian and military populations. We sought to determine and compare the prevalence of skin conditions between civilian and military populations. A total of 3382 male patients (1148 military and 2234 civilian) were retrospectively and consecutively evaluated at Merzifon Military Hospital in the central Black Sea Region of Turkey. The most frequent dermatological condition was tinea pedis (15.8%) followed by acne vulgaris, allergic contact dermatitis and alopecia areata in the military population (15.7%, 7.7% and 5.4%, respectively). Acne vulgaris, xerosis cutis and allergic contact dermatitis were the most common diagnoses in the civilian group (19.4%, 14.1% and 9.1%, respectively). The prevalence of tinea pedis, alopecia areata, pityriasis versicolor, ingrown nail (unguis incarnatus) and callus were statistically significantly higher in the military group (15.8% vs 4.4%, p<0.001; 5.4% vs 1.7%, p<0.05; 3.5% vs 0.7%, p<0.001; 3.3% vs 0.3%, p<0.001 and 4.6% vs 0.9%, p<0.001; respectively). Xerosis cutis was found to be significantly higher in the civilian group (14.1% vs 5.8%, p<0.001). Superficial fungal disease was the most prevalent disorder as in the previous literature. Preventive measures should be taken to improve the health of troops and reduce the prevalence of the common disorders such as tinea pedis, alopecia areata and callus. Troops should wear boots only when necessary in base camps. Clothing which reduces ventilation is not recommended. Depression and anxiety should be recognised and treated in soldiers with alopecia areata, as a solely dermatological approach without psychological support may reduce treatment success.

Scrotal Rejuvenation

PubMed Central

2018-01-01

Genital rejuvenation is applicable not only to women (vaginal rejuvenation) but also to men (scrotal rejuvenation). There is an increased awareness, reflected by the number of published medical papers, of vaginal rejuvenation; however, rejuvenation of the scrotum has not received similar attention in the medical literature. Scrotal rejuvenation includes treatment of hair-associated scrotal changes (alopecia and hypertrichosis), morphology-associated scrotal changes (wrinkling and laxity), and vascular-associated scrotal changes (angiokeratomas). Rejuvenation of the scrotum potentially may utilize medical therapy, such as topical minoxidil and oral finasteride, for scrotal alopecia and conservative modalities, such as depilatories and electrolysis, for scrotal hypertrichosis. Lasers and energy-based devices may be efficacious for scrotal hypertrichosis and scrotal angiokeratomas. Surgical intervention is the mainstay of therapy for scrotal laxity; however, absorbable suspension sutures are postulated as a potential intervention to provide an adequate scrotal lift. Hair transplantation for scrotal alopecia and injection of botulinum toxin into the dartos muscle for scrotal wrinkling are hypothesized as possible treatments for these conditions. The interest in scrotal rejuvenation is likely to increase as men and their physicians become aware of both the conditions of the scrotum that may warrant rejuvenation and the potential treatments of the scrotum for these individuals.

Andean bear (Tremarctos ornatus) alopecia syndrome (ABAS) commonly affects captive bears, particularly sexually mature females. ABAS is characterized by bilaterally symmetrical predominantly flank alopecia with or without profound pruritus and secondary bacterial and Malassezia infections. There is no effective treatment and severely affected bears have been euthanized. This paper describes the successful management of ABAS in three female Andean bears. Skin biopsies and cytology revealed a mixed dermal inflammatory infiltrate, alopecia, hyperkeratosis, and Malassezia dermatitis. Allergen specific serology was positive for environmental allergens in one case. Hematology, serum biochemistry, and thyroid and adrenal function were normal in all cases. There was no consistent response to novel diet trials, antifungals, antihistamines, allergen specific immunotherapy, or topical antimicrobials. There was a partial response to ciclosporin (Atopica® cat, Novartis Animal Health; 5 mg/kg po, sid) in one case and oral glucocorticoids in all cases (dexamethasone sodium phosphate, [Colvasone 0.2%, Norbrook], 0.15 mg/kg po, sid or prednisolone [Deltacortene, Bruno Farmaceutici, and Megasolone 20, Coophavet], 0.3-1.2 mg/kg po, sid), but treatment was withdrawn following adverse effects. Treatment with oclacitinib maleate (Apoquel®, Zoetis; 0.46-0.5 mg/kg po, bid) resulted in rapid and complete resolution of the pruritus with subsequent improvement in demeanor and fur regrowth. After 5 mo, the bears were almost fully furred and off all other medication. Treatment was tapered to the lowest dose that prevented relapse of the pruritus (0.23-0.4 mg/kg po, sid). No adverse effects have been noted. ABAS is usually an intractable condition, and, to our knowledge, oclacitinib is the first treatment shown to result in sustained clinical improvement. Further studies on the etiology of ABAS, and on efficacy and long-term safety of oclacitinib are needed.

A controlled, randomized, double-blind, parallel-group study compared the effects of ViviScal (a new food supplement incorporating special marine extracts and a silica compound) with those of a fish extract in the treatment of young males with hereditary androgenic alopecia. The pretreatment histological diagnosis was alopecia with a mild to moderate perifollicular inflammation zone. The study consisted of 20 subjects who received two tablets of ViviScal once daily and 20 who received two tablets of fish extract once daily for 6 months. The mean patient age and mean duration and severity of baldness compared well between the two groups. Most patients had been treated with long-term topical 2% minoxidil for 1 year or more prior to the study. At baseline and after 6 months' treatment, a biopsy was taken for histological examination. A non-vellus hair count was performed at baseline and after 2, 4 and 6 months. In the fish extract treatment group three patients withdrew from the study before the fourth month due to lack of therapeutic effect. After 6 months' treatment, patients receiving ViviScal showed a mean increase in non-vellus hair of 38% compared with a 2% increase in the fish extract treatment group (P < 0.0001). In the ViviScal group, 19 (95%) subjects showed both clinical and histological cure, whereas none treated with fish extract showed any clinical or histological difference after 6 months' treatment (P < 0.0001). In both groups, a minimal decrease in the erythemal index was observed. In conclusion, ViviScal appears to be the first highly active treatment for androgenic alopecia in young males.

Alopecia areata (AA) is a dermatological disease characterized by non-scarring hair loss of the scalp and/or body, with an unpredictable and variable evolution in the patients in which, despite multidisciplinary efforts, its etiology is not entirely known, although some evidence suggests that environmental, immunological and genetic factors could be generating the disease. The aim of this review is to provide an updated panorama of the clinical characteristics, diagnosis and treatment of AA, to analyze the mechanisms that could participate in its etiology, as well as to review some of the most important genetic variants that could confer susceptibility to the development of this disease.

Background This study aimed to estimate the point prevalence of myositis and identify associated variables of myositis in systemic lupus erythematosus (SLE). Material/Methods Clinical date of patients hospitalized with lupus at the First Affiliated Hospital of Anhui Medical University and Anhui Provincial Hospital were collected. Patients were defined as having myositis if they reported the presence of persistent invalidating muscular weakness combined with increased levels of creatine phosphokinase (CPK) and abnormal electromyography (EMG). Results The study sample comprised 1701 lupus patients, of which 44 had myositis. Patients with SLE-associated myositis are more likely to have skin rash, alopecia, pericarditis, vasculitis, anti-Sm, anti-RNP, anti-dsDNA, thrombocytopenia, leukopenia, low C3, low C4, high erythrocyte sedimentation rate (ESR), high D-dimer, and active disease. Multivariate logistic regression found positive associations between leukopenia, alopecia, and active disease with myositis. Negative associations between myositis with the use of corticosteroids or immunosuppressive drugs were revealed in univariate and multivariate analysis. Conclusions The point prevalence of myositis was 2.6% in SLE patients. The significant association of alopecia, leukopenia, and active disease with myositis suggests that organ damage, hematological abnormality, and high disease activity promote the progression of myositis in lupus patients.

Friedman, Shelly; Schnoor, Patricia

2017-06-01

Photobiomodulation, also referred to as low-level laser therapy (LLLT), has been studied and used for (among other diseases) the promotion of hair regrowth. 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. The study demonstrates that low-level laser treatment of the scalp every other day for 17 weeks using the HANDI-DOME LASER device is a safe and effective treatment for androgenetic alopecia in healthy females between the ages of 18 to 60 with Fitzpatrick skin Types I to IV and Ludwig-Savin Baldness Scale I-2 to II-2 baldness patterns. Subjects receiving LLLT at 650 nm achieved a 51% increase in hair counts as compared with sham-treated control patients in this multicenter randomized controlled trial. These results suggest that the emerging technology of low-level laser therapy may play a potentially significant role in health care providers' armamentarium for the disease androgenic alopecia.

Many biochemical pathways involved in hair and skin development have not been investigated. Here, we reported on the lesions and investigated the mechanism underlying hair and skin abnormalities in Zdhhc13(skc4) mice with a deficiency in DHHC13, a palmitoyl-acyl transferase encoded by Zdhhc13. Homozygous affected mice showed ragged and dilapidated cuticle of the hair shaft (CUH, a hair anchoring structure), poor hair anchoring ability, and premature hair loss at early telogen phase of the hair cycle, resulting in cyclic alopecia. Furthermore, the homozygous affected mice exhibited hyperproliferation of the epidermis, disturbed cornification, fragile cornified envelope (CE, a skin barrier structure), and impaired skin barrier function. Biochemical investigations revealed that cornifelin, which contains five palmitoylation sites at cysteine residues (C58, C59, C60, C95, and C101), was a specific substrate of DHHC13 and that it was absent in the CUH and CE structures of the affected mice. Furthermore, cornifelin levels were markedly reduced when two palmitoylated cysteines were replaced with serine (C95S and C101S). Taken together, our results suggest that DHHC13 is important for hair anchoring and skin barrier function and that cornifelin deficiency contributes to cyclic alopecia and skin abnormalities in Zdhhc13(skc4) mice.

We present a follow-up case report of a 33-year-old lady with juvenile onset arthritis who developed halo naevi while on treatment with tocilizumab. This case report describes the development of halo naevi, vitiligo and diffuse alopecia areata associated with tocilizumab therapy following infection with Methicillin-resistant Staphylococcus aureus (MRSA) and Panton–Valentine leukocidin positivity. This is the first case that describes these events and supports previous theories on cellular and humoral immunity as causative factors. The regression of melanocytes during treatment with tocilizumab could also implicate IL-6 and sIL-6R as future targets in the treatment of melanoma through its direct effect of melanocytic cytotoxicity, which supports previous studies.

Alopecia Areata (AA) is a non-scarring alopecia that affects millions of Americans, however the way it is treated and which patients seek treatment is not well characterized. To better understand how AA was being treated in the United States, what type of patients are seen for AA, and what physicians treated them. We analyzed data from the National Ambulatory Medical Care Survey (NAMCS) and National Hospital Ambulatory Medical Care Survey (NHAMCS) from 2001 to 2010. We tabulated patient characteristics, the physicians who treated AA and what treatments were prescribed for AA. There were an estimated 2.6 million outpatient visits for AA. Patients with AA were most commonly treated by a dermatologists (84.8%). Patients were most commonly treated with topical and injected corticosteroids (61.0%) followed by minoxidil (5.9%) and topical tacrolimus (5.7%). Males made fewer visits per 1,000 capita compared to females (P=0.01). The NAMCS and NHAMCS do not record severity of disease data. Topical and injected corticosteroids are the mainstay of treatment for AA, however the use of steroid sparing agents such as minoxidil is low. Despite no studies demonstrating efficacy, topical tacrolimus was used almost as frequently as minoxidil.

Female Pattern Hair Loss: a clinical and pathophysiological review*

2015-01-01

Female Pattern Hair Loss or female androgenetic alopecia is the main cause of hair loss in adult women and has a major impact on patients' quality of life. It evolves from the progressive miniaturization of follicles that lead to a subsequent decrease of the hair density, leading to a non-scarring diffuse alopecia, with characteristic clinical, dermoscopic and histological patterns. In spite of the high frequency of the disease and the relevance of its psychological impact, its pathogenesis is not yet fully understood, being influenced by genetic, hormonal and environmental factors. In addition, response to treatment is variable. In this article, authors discuss the main clinical, epidemiological and pathophysiological aspects of female pattern hair loss. PMID:26375223

Androgenetic alopecia. Battling a losing proposition.

PubMed

Rubin, M B

1997-08-01

Some degree of hair loss with aging is inevitable in both men and women. The exact underlying mechanism is not well understood. Although genetic factors have a role in the development of androgenetic alopecia, the outcome in an individual patient cannot be reliably predicted on the basis of family history. Balding tends to begin earlier in men and to develop in well-recognized patterns. Women have more diffuse hair loss that often occurs after menopause. The available treatment options, such as topical minoxidil therapy, hair transplantation, and other surgical techniques, are not very successful. Lessening patients' anxiety about hair loss by reassuring them that they will not go totally bald immediately may be the most effective management.

Testosterone is necessary for the development of male pattern baldness, known as androgenetic alopecia (AGA); yet, the mechanisms for decreased hair growth in this disorder are unclear. We show that prostaglandin D2 synthase (PTGDS) is elevated at the mRNA and protein levels in bald scalp compared to haired scalp of men with AGA. The product of PTGDS enzyme activity, prostaglandin D2 (PGD2), is similarly elevated in bald scalp. During normal follicle cycling in mice, Ptgds and PGD2 levels increase immediately preceding the regression phase, suggesting an inhibitory effect on hair growth. We show that PGD2 inhibits hair growth in explanted human hair follicles and when applied topically to mice. Hair growth inhibition requires the PGD2 receptor G protein (heterotrimeric guanine nucleotide)–coupled receptor 44 (GPR44), but not the PGD2 receptor 1 (PTGDR). Furthermore, we find that a transgenic mouse, K14-Ptgs2, which targets prostaglandin-endoperoxide synthase 2 expression to the skin, demonstrates elevated levels of PGD2 in the skin and develops alopecia, follicular miniaturization, and sebaceous gland hyperplasia, which are all hallmarks of human AGA. These results define PGD2 as an inhibitor of hair growth in AGA and suggest the PGD2-GPR44 pathway as a potential target for treatment. PMID:22440736

Chemotherapy-induced alopecia is a common and distressing adverse event for patients. Scalp cooling to reduce this alopecia has been available in Europe for more than a decade, but only recently introduced in Australia. The aim of this study was to qualitatively explore health professionals' perceptions of the barriers and enablers to the implementation of scalp cooling in Australian cancer centres. Using a qualitative methodology, telephone interviews were conducted with 21 health professionals working in a tumour stream where chemotherapy-induced alopecia is an adverse event of treatment. Participants were recruited from five centres in Australia where scalp cooling is currently available and one centre without access to the technology. Four interrelated themes were identified: (1) health professional attitudes, (2) concerns for patient equity, (3) logistical considerations and (4) organisational support. This qualitative study provides the first methodological exploration of Australian health professionals' perceptions of barriers and enablers to scalp cooling uptake. The results highlighted health professional support drives the introduction of scalp cooling. Integration of the technology requires adjustments to nursing practice to manage the increased time, workload and change in patient flow. Strategies to manage the change in practice and organisational support for change in work flow are essential for successful implementation into routine care.

Female-patterned alopecia in teenage brothers with unusual histologic features.

Patterned hair loss, follicular miniaturization, and increased telogen hair counts characterize androgenic alopecia (AGA). Follicular inflammation in AGA has been associated with treatment resistance and progressive hair loss. Brothers, 15 and 18 years old, presented with frontal and mid-scalp hair loss with an intact frontal hairline noted over a 1-year period. The elder reported past use of androgenic steroids. Laboratory assessment for metabolic and hormonal abnormalities was unrevealing, and hair pull test was negative. Scalp biopsies revealed decreased terminal hairs, marked diameter variation of anagen hairs, decreased terminal to vellus hair ratios (3.7:1/3.4:1, older/younger), and increased telogen counts (23%/21%). Infrabulbar and peri-isthmic (follicular bulge region) lymphocytic infiltrates were present. Hair loss has progressed, unabated by daily topical 0.5% clobetasol (for 6 months), daily 5% minoxidil (1 year), and latter, daily oral finasteride (2 years - older brother only). Based on patterned hair loss and miniaturized hairs, these brothers have AGA. The female pattern of hair loss (diffuse hair loss affecting the central scalp with preservation of frontal hair line) coupled with follicular isthmic lymphocytic inflammation represents an unusual presentation, possibly a treatment resistant, inflammatory variant of AGA. The differential diagnosis includes exogenous androgen-mediated hair loss, cicatricial pattern hair loss, or the superimposition of alopecia areata.

Purpose Demodex infestations cause blepharitis and are difficult to treat. Recently, a new type of eyelid wipes with terpenoids has been found effective. We aim to evaluate patient satisfaction after short-term use and compare two teaching modalities on the techniques of use. Patients and methods Eligible participants were taught to use eyelid wipes (Cliradex®) by either live or online video demonstration based on random allocation. Participants used the wipes twice daily for a week. All participants had prior evaluation of socioeconomic status, dry eye symptoms, and meibomian gland features. After 1 week, competence of use was assessed by participants showing their technique to the investigator, and a questionnaire on comfort, ease, and convenience of use was administered. Higher scores indicate greater satisfaction, and these levels are compared among the two teaching modalities using chi square. Results A total of 50 participants were recruited, with a mean age of 42±16 years, and 88% of the participants were females. Overall, median comfort level was 4.0 (range: 1–6), ease level was 5.0 (3–6), and convenience level was 5.0 (2–6). Median stinging was 2.0 (1–4), which corresponded to some but mild stinging. The median competence level was 4.0 (2–4), which corresponded to excellent competence. These satisfactory levels (ease, comfort, and convenience) experienced were not significantly associated with different socioeconomic indicators, that is, housing type, income, highest education level, and were not different between teaching methods (p>0.05). Conclusion Short-term use of Cliradex eyelid wipes seems to be acceptable to most people. The teaching instructions before using these wipes were equally effective – whether live or online video demonstration was used. PMID:29379270

Androgenetic alopecia, or male/female pattern baldness, is the most common type of progressive hair loss disorder. The aim of this paper is to review recent advances in non-surgical treatments for androgenetic alopecia and identify the most effective treatments. A network meta-analysis (NMA) was conducted of the available literature of the six most common non-surgical treatment options for treating androgenetic alopecia in both men and women; dutasteride 0.5mg, finasteride 1mg, low level laser therapy (LLLT), minoxidil 2%, minoxidil 5% and platelet rich plasma (PRP). Seventy-eight studies met the inclusion criteria and twenty-two studies had the data necessary for a network meta-analysis. Relative effects show LLLT as the superior treatment. Relative effects show PRP, finasteride 1 mg (male), finasteride 1 mg (female), minoxidil 5%, minoxidil 2% and dutasteride (male) are approximately equivalent in mean change hair count following treatment. Minoxidil 5% and minoxidil 2% reported the most drug-related adverse events (n=45 and n=23, respectively). The quality of evidence of minoxidil 2% vs. minoxidil 5% was high; minoxidil 5% vs. placebo was moderate; dutasteride (male) vs. placebo, finasteride (female) vs placebo, minoxidil 2% vs. placebo, minoxidil 5% vs. LLLT was low and finasteride (male) vs. placebo, LLLT vs. sham, PRP vs. placebo, finasteride vs. minoxidil 2% was very low. Results of this NMA indicate the emergence of novel, non-hormonal therapies as effective treatments for hair loss; however, the quality of evidence is generally low. High quality randomized controlled trials and head to head trials are required to support these findings and aid in the development of more standardized protocols, particularly for PRP. Regardless, this analysis may aid physicians in clinical decision making and highlight the variety of non-surgical hair restoration options for patients. This article is protected by copyright.

Follicular delivery of spironolactone via nanostructured lipid carriers for management of alopecia

PubMed Central

Shamma, Rehab Nabil; Aburahma, Mona Hassan

2014-01-01

Spironolactone (SL) is a US Food and Drug Administration-approved drug for the treatment of hypertension and various edematous conditions. SL has gained a lot of attention for treating androgenic alopecia due to its potent antiandrogenic properties. Recently, there has been growing interest for follicular targeting of drug molecules for treatment of hair and scalp disorders using nanocolloidal lipid-based delivery systems to minimize unnecessary systemic side effects associated with oral drug administration. Accordingly, the objective of this study is to improve SL efficiency and safety in treating alopecia through the preparation of colloidal nanostructured lipid carriers (NLCs) for follicular drug delivery. SL-loaded NLCs were prepared by an emulsion solvent diffusion and evaporation method using 23 full factorial design. All of the prepared formulations were spherical in shape with nanometric size range (215.6–834.3 nm) and entrapment efficiency >74%. Differential scanning calorimetry thermograms and X-ray diffractograms revealed that SL exists in amorphous form within the NLC matrices. The drug release behavior from the NLCs displayed an initial burst release phase followed by sustained release of SL. Confocal laser scanning microscopy confirmed the potential of delivering the fluorolabeled NLCs within the follicles, suggesting the possibility of using SL-loaded NLCs for localized delivery of SL into the scalp hair follicles.

Androgenetic alopecia (AGA) is a genetically determined progressive hair-loss condition which represents the most common cause of hair loss in men. The use of the medical term androgenetic alopecia reflects current knowledge about the important role of androgens and genetic factors in its etiology. In addition to androgen-dependent changes in the hair cycle, sustained microscopic follicular inflammation contributes to its onset. Furthermore, Prostaglandins have been demonstrated to have the ability in modulating hair follicle cycle; in particular, PGD2 inhibits hair growth while PGE2/F2a promote growth. Due to the progressive nature of AGA, the treatment should be started early and continued indefinitely, since the benefit will not be maintained upon ceasing therapy. To date, only two therapeutic agents have been approved by the Food and Drug Administration and European Medicines Agency for the treatment of AGA: topical minoxidil and oral finasteride. Considering the many pathogenetic mechanisms involved in AGA, various treatment options are available: topical and systemic drugs may be used and the choice depends on various factors including grading of AGA, patients' pathological conditions, practicability, costs and risks. So, the treatment for AGA should be based on personalized therapy and targeted at the different pathophysiological aspects of AGA. © 2016 Wiley Periodicals, Inc.

Epidemiological studies found that hepatitis E virus genotype 3 (HEV-3) infection was associated with chronic hepatitis and cirrhosis in immunocompromised patients. Our study aimed to investigate the relationship between the host immunosuppressive status and the occurrence of HEV-related chronic hepatitis. Here we describe a successful experimental study, using cynomolgus monkeys previously treated with tacrolimus, a potent calcineurin inhibitor immunosuppressant, and infected with a Brazilian HEV-3 strain isolated from naturally infected pigs. HEV infected monkeys were followed up during 160 days post infection (dpi) by clinical signs; virological, biochemical and haematological parameters; and liver histopathology. The tacrolimus blood levels were monitored throughout the experiment. Immunosuppression was confirmed by clinical and laboratorial findings, such as: moderate weight loss, alopecia, and herpes virus opportunistic infection. In this study, chronic HEV infection was characterized by the mild increase of liver enzymes serum levels; persistent RNA viremia and viral faecal shedding; and liver histopathology. Three out of four immunosuppressed monkeys showed recurrent HEV RNA detection in liver samples, evident hepatocellular ballooning degeneration, mild to severe macro and microvesicular steatosis (zone 1), scattered hepatocellular apoptosis, and lobular focal inflammation. At 69 dpi, liver biopsies of all infected monkeys revealed evident ballooning degeneration (zone 3), discrete hepatocellular apoptosis, and at most mild portal and intra-acinar focal inflammation. At 160 dpi, the three chronically HEV infected monkeys showed microscopic features (piecemeal necrosis) corresponding to chronic hepatitis in absence of fibrosis and cirrhosis in liver parenchyma. Within 4-months follow up, the tacrolimus-immunosuppressed cynomolgus monkeys infected with a Brazilian swine HEV-3 strain exhibited more severe hepatic lesions progressing to chronic hepatitis without liver fibrosis, similarly as shown in tacrolimus-immunosuppressed solid organ transplant (SOT) recipients. The cause-effect relationship between HEV infection and tacrolimus treatment was confirmed in this experiment. PMID:28328941

Histologic features of alopecia areata other than peribulbar lymphocytic infiltrates.

Histologic features other than a lymphocytic infiltrate around follicular bulbs are now recognized as helpful clues to the diagnosis of alopecia areata, especially in long-standing lesions where the peribulbar lymphocytic infiltrate may be sparse or absent. We sought to determine the frequency of peribulbar lymphocytic infiltrates, eosinophils, lymphocytes, and melanin in fibrous tracts, pigment casts in follicles, the presence of catagen/telogen follicles, follicular miniaturization, and dystrophic ("nanogen") follicles in alopecia areata. Secondly, we sought to compare the diagnostic use of transversely sectioned versus horizontally sectioned specimens in those cases for which both were available (15 of 109 cases). The pathology archives of Geisinger Medical Center (Danville, PA), Wilford Hall US Air Force Medical Center (San Antonio, TX), and Brooke US Army Medical Center (San Antonio, TX) were searched for the term "alopecia areata" in the diagnostic field from the period of 1991 to 2006, which yielded 109 cases with sections suitable for review. Cases from the two military institutions from 1997 or earlier were excluded to avoid any overlap with data previously reported by our group. A peribulbar lymphocytic infiltrate was present in 92 specimens (84%), eosinophils in fibrous tracts in 48 (44%), lymphocytes in fibrous tracts in 102 (94%), melanin within fibrous tracts in 92 (84%), pigment casts within follicular canals in 46 (44%), catagen follicles in 101 (93%), and miniaturized follicles in 98 (90%). Dystrophic miniaturized follicles were rare (4 cases). In 14 of 15 cases with both vertical and transverse sections, either was diagnostic. One case showed diagnostic features only in vertical sections. Comparable vertical and transverse sections were only available for a limited number of the cases. We did not correlate duration of disease with individual findings. Our results were correlated with the clinical diagnosis but not with serologic tests for syphilis. Although most specimens showed evidence of a peribulbar lymphocytic infiltrate (84%), a higher percentage showed evidence of follicles in catagen/telogen phase (93%) and evidence of miniaturization of follicles (90%). This could lead to an incorrect diagnosis of trichotillomania or pattern alopecia. Pigment casts within the hair canal were also found in a significant number of follicles, especially in catagen follicles, creating further potential for misdiagnosis as trichotillomania. A significant percentage showed evidence of eosinophils (44%), melanin (84%), and lymphocytes (94%) in fibrous tracts. These features are particularly helpful when a peribulbar lymphocytic infiltrate is lacking. Vertical and transverse sections appear comparable. Copyright © 2011 American Academy of Dermatology, Inc.

Background Alopecia is the common hair loss problem that can affect many people. However, current therapies for treatment of alopecia are limited by low efficacy and potentially undesirable side effects. We have identified a new function for valproic acid (VPA), a GSK3β inhibitor that activates the Wnt/β-catenin pathway, to promote hair re-growth in vitro and in vivo. Methodology/ Principal Findings Topical application of VPA to male C3H mice critically stimulated hair re-growth and induced terminally differentiated epidermal markers such as filaggrin and loricrin, and the dermal papilla marker alkaline phosphatase (ALP). VPA induced ALP in human dermal papilla cells by up-regulating the Wnt/β-catenin pathway, whereas minoxidil (MNX), a drug commonly used to treat alopecia, did not significantly affect the Wnt/β-catenin pathway. VPA analogs and other GSK3β inhibitors that activate the Wnt/β-catenin pathway such as 4-phenyl butyric acid, LiCl, and BeCl2 also exhibited hair growth-promoting activities in vivo. Importantly, VPA, but not MNX, successfully stimulate hair growth in the wounds of C3H mice. Conclusions/ Significance Our findings indicate that small molecules that activate the Wnt/β-catenin pathway, such as VPA, can potentially be developed as drugs to stimulate hair re-growth.

Recent developments in research methods and techniques, such as whole-exome and -genome sequencing, have substantially improved our understanding of genetic conditions. Special progress has been made in the field of genotrichoses, or hereditary hair diseases, a field that has been obscure for many years. The underlying genes for many of the monogenic hair diseases are now known. Additionally, complex analyses of large cohorts of patients have given us the first clues to the genes associated with polygenic hair disorders, such as androgenetic alopecia and alopecia areata. Thanks to these major findings, the sophisticated regulation of the morphogenesis, development and growth of hair follicles has begun to be revealed, and new players in this delicate molecular interplay have been exposed. © 2015 S.

2016-01-01

Introduction: Photobiostimulation with low level laser (LLL) has been used in medicine for a long time and its effects have been shown in many diseases. Some studies have evaluated the effect of LLL on androgenic alopecia. One of the most important limitations of the use of LLL in the treatment of alopecia is the requirement for multiple sessions, which is hardly accepted by patients. This study was conducted to evaluate the effect of the irradiation of extracted follicular hair units by LLL on the outcome of hair transplantation. Methods: We enrolled 10 patients with androgenic alopecia and after screening tests for infections and other diseases, we extracted hair follicular units. The hair units were divided in two groups. One group was irradiated by LLL 20 minutes before transplantation (660 nm, 80 Hz, 100 mW) and the other one was used as control. The containing plates were labeled as A and B and sent to the operation room. The surgeon was unaware of the therapy assigned to the plates and transplanted them randomly on the right or left side of the head. One hundred follicular units on each sides of the scalp were transplanted symmetrically. The follicles on both sides were evaluated at 3 and 6 months of transplantation for hair growth rate by another physician, blinded to the treatment assigned to each side. Results: Ten patient with androgenic alopecia and mean (SD) age of 31.5 (6.6) years (range 25-45 years) completed the study. All patients had 100% hair growth at 3 and 6 months follow-up except one who had hair growth of 20% at three months of transplantation, which changed to 100% at sixth months. There was no significant difference between the groups regarding hair growth (P > 0.8). Conclusion: One session of LLL irradiation has no significant effect on the outcome of transplanted hair follicles. Studies with larger sample size are needed to draw a definite conclusion.

Although twice-daily application of propylene glycol-containing 2% minoxidil topical solution (MTS) stimulates new hair growth, higher concentrations of minoxidil in a once-daily, propylene glycol-free formulation may improve efficacy and reduce unpleasant side effects. We sought to compare the efficacy, safety, and acceptability and to show noninferiority of once-daily 5% minoxidil topical foam (MTF) with twice-daily 2% MTS in women with androgenetic alopecia. A total of 113 women with androgenetic alopecia were randomized to 24 weeks of treatment with 5% MTF or 2% MTS. The primary efficacy parameter was change from baseline in nonvellus target area hair count at week 24. Secondary end points included change in nonvellus target area hair width, overall efficacy by global photographic review as assessed by treatment-blinded evaluators and the subject herself, adverse events, and participants' assessment of product aesthetics. After 24 weeks, women randomized to 5% MTF once daily showed noninferior target area hair count and target area hair width and experienced greater, but nonsignificant, improvements in target area hair count, target area hair width, and overall efficacy by global photographic review than those randomized to 2% MTS used twice daily. 5% MTF was significantly superior to 2% MTS in participants' agreement with "the treatment does not interfere with styling my hair" (P = .002). Women randomized to 5% MTF experienced significantly lower rates of local intolerance (P = .046) especially in pruritus and dandruff compared with 2% MTS. Because of differences in the formulations tested, study participants were not blinded to treatment. Once-daily 5% MTF is noninferior and as effective for stimulating hair growth as twice-daily 2% MTS in women with androgenetic alopecia and is associated with several aesthetic and practical advantages.

Perifolliculitis capitis abscedens et suffodiens (PCAS) is rare chronic, suppurative and inflammatory scalp disease. Its aetiology and pathogenesis is not completely understood. The treatment is usually difficult and often disappointing. We report a case of 25-year-old male who presented with tender, fluctuant nodules and abscesses, with draining pus and patchy alopecia on his scalp for 3 years. A skin biopsy from scalp lesions revealed features that are characteristic of perifolliculitis. Initially, the patient was treated with periodic incision and drainage of the scalp abscesses. The answer was very poor. When admitted to our department, isotretinoin was started at daily dose of 30 mg, because initially his cholesterol and triglyceride levels were mildly increased. When dose was reduced to 10 mg the levels of cholesterol and triglyceride remained normal. A response to treatment was excellent and rapid. The treatment of PCAS represents usually difficulties and frustration for both the patient and the physician. A long course of isotretinoin can be considered as one of the most effective treatment for PCAS.

Boudghène-Stambouli, O; Mérad-Boudia, A

1998-10-01

Dermatophytic disease is a chronic dermatophytosis involving the skin and viscera and caused by benign dermatophytes which cross the skin barrier. We present a case presenting previously unreported giant cutaneous horns. A male Algerian patient aged 29 years consulted for chronic skin disease which had progressed for 2 years. Manifestations included warts, papulonodules, eczematiform lesions, lichenifications, alopecia, onyxis, multiple node enlargement and giant cutaneous horns on the plantar aspect of the feet making walking difficult. The patient's kinhood included 10 members and the patient's parents were first cousins; no other family member had a similar disease state. Laboratory findings included eosinophilia (11%, 550 cells/mm3), an inflammatory syndrome, and normal phosphorus and calcium levels despite demineralization of the hands and feet. The tuberculin interdermal reaction was positive but the trichophytine interdermal reaction was negative. Trichophyton violaceum was found in all mycological samples from skin and nails. The histology examination of skin biopsies revealed acanthosis, considerable hyperkeratosis, and myceleal filaments invading the horny layer, the sweat glands and hair follicles. Abscesses and granulomas were also seen in the superficial dermis. Oral griseofulvin 1 g per day and topical applications with ketoconazole gave clear improvement. Dermatophytic disease is a chronic dermatophytosis observed mainly in North Africa. The locally high rate of consanguinous marriages would suggest autosomal recessive inheritance of a genetic anomaly possibly associated with deficient cellular immunity. The lesions are polymorphous and develop progressively, probably due to diminished cellular immunity. This case with giant cutaneous horns would be a new variant. Antifungals can provide definitive cure. The pathogenesis of this severe dermatophytosis remains to be established.

Epizootic of sarcoptic mange in raccoon dogs (Nyctereutes procyonoides) in relation to population density.

To examine outbreaks of mange in raccoon dogs (Nyctereutes procyonoides) with respect to population density, we analyzed camera trap videos, and isolated mites from raccoon dog carcasses. In a camera trapping survey, we categorized the skin condition of raccoon dogs, and used a number of independent videos to calculate the relative abundance index (RAI). The RAI of raccoon dogs with alopecia increased following an increase in the RAI of those without alopecia. Among 27 raccoon dog carcasses, 12 showed mange-compatible skin lesions. Sarcoptes scabiei was isolated from 11 of these raccoon dogs, indicating that sarcoptic mange was endemic in our study area. Therefore, a high relative population density may be a factor underlying epizootics of sarcoptic mange in raccoon dogs.

Iontophoresis-targeted, follicular delivery of minoxidil sulfate for the treatment of alopecia.

2013-05-01

Although minoxidil (MX) is a drug known to stimulate hair growth, the treatment of androgenic alopecia could be improved by delivery strategies that would favor drug accumulation into the hair follicles. This work investigated in vitro the potential of iontophoresis to achieve this objective using MX sulfate (MXS), a more water-soluble derivative of MX. Passive delivery of MXS was first determined from an ethanol-water solution and from a thermosensitive gel. The latter formulation resulted in greater accumulation of MXS in the stratum corneum (skin's outermost layer) and hair follicles and an overall decrease in absorption through the skin. Anodal iontophoresis of MXS from the same gel formulation was then investigated at pH 3.5 and pH 5.5. Compared with passive delivery, iontophoresis increased the amount of drug reaching the follicular infundibula from 120 to 600 ng per follicle. In addition, drug recovery from follicular casts was threefold higher following iontophoresis at pH 5.5 compared with that at pH 3.5. Preliminary in vivo experiments in rats confirmed that iontophoretic delivery of MXS facilitated drug accumulation in hair follicles. Overall, therefore, iontophoresis successfully and significantly enhanced follicular delivery of MX suggesting a useful opportunity for the improved treatment of alopecia.

Follicular delivery of spironolactone via nanostructured lipid carriers for management of alopecia.

PubMed

Shamma, Rehab Nabil; Aburahma, Mona Hassan

2014-01-01

Spironolactone (SL) is a US Food and Drug Administration-approved drug for the treatment of hypertension and various edematous conditions. SL has gained a lot of attention for treating androgenic alopecia due to its potent antiandrogenic properties. Recently, there has been growing interest for follicular targeting of drug molecules for treatment of hair and scalp disorders using nanocolloidal lipid-based delivery systems to minimize unnecessary systemic side effects associated with oral drug administration. Accordingly, the objective of this study is to improve SL efficiency and safety in treating alopecia through the preparation of colloidal nanostructured lipid carriers (NLCs) for follicular drug delivery. SL-loaded NLCs were prepared by an emulsion solvent diffusion and evaporation method using 23 full factorial design. All of the prepared formulations were spherical in shape with nanometric size range (215.6-834.3 nm) and entrapment efficiency >74%. Differential scanning calorimetry thermograms and X-ray diffractograms revealed that SL exists in amorphous form within the NLC matrices. The drug release behavior from the NLCs displayed an initial burst release phase followed by sustained release of SL. Confocal laser scanning microscopy confirmed the potential of delivering the fluorolabeled NLCs within the follicles, suggesting the possibility of using SL-loaded NLCs for localized delivery of SL into the scalp hair follicles.

Effective treatment options for alopecia areata (AA) are missing. Whether lasers might be effective is a topic of debate. We aimed to evaluate whether neodymium: yttrium aluminum garnet (Nd:YAG) or fractional carbon dioxide lasers might stimulate the development of new hair. Thirty-two patients who had long-standing and treatment refractory diseases were recruited for the study. Three different patches on the scalp were selected, 1 of which served as control. The mean outcome measure was the hair count, which was calculated with the digital phototrichogram. Response was defined as at least 25% increase in the mean hair count at the treated patch compared with the control patch. At the end of the study, there was no statistically significant difference in the mean hair count for the 3 patches. In 7 of 32 patients (22%), an increase in the mean hair count was observed on the whole scalp including the control patch, which resulted in an improved Severity of Alopecia Tool (SALT) score. We have observed that Nd:YAG or fractional carbon dioxide lasers did not increase the mean hair count on the treated AA patches when compared with the control patch. However, an SALT score improvement in 22% of the patients suggested spontaneous remission.

Three hundred and eight nanometer excimer light therapy has recently been reported to be effective against patchy alopecia areata (AA) in several clinical studies. However, these studies only included a few patients with severe forms of AA, and all of them exhibited poor outcomes. We further investigated the use of excimer light as a therapeutic option for cases of alopecia universalis (AU) that are resistant to other treatments. Eleven treatment-resistant AU patients were treated with a 308-nm excimer light at 2-week intervals for more than 16 sessions. Four patients achieved good responses and two patients exhibited poor responses. Three patients had Japanese skin type 1 and all of them achieved good responses. The radiation dose was increased until the patients exhibited marked erythema. The patients with Japanese skin type 3 who achieved good responses exhibited strong pigmentation at the irradiated sites. In conclusion, 308-nm excimer light therapy has significant effects on some AU patients who are resistant to other treatments and may be an alternative therapeutic option for AU. During the treatment of AU, high doses of radiation should be administrated until a strong inflammatory skin reaction is seen. © 2016 Japanese Dermatological Association.

Evidence for the possible occurrence of Grave's disease in a blue-eyed black lemur (Eulemur flavifrons).

The blue-eyed black lemur (Eulemur flavifrons) is classified by the International Union for Conservation of Nature (IUCN) as critically endangered. A 23-year-old male housed at Mulhouse Zoo presented with lethargy, polyphagia, alopecia, and chronic weight loss. Clinical examination suggested an endocrine pathology such as hyperthyroidism. Secondary examinations included cervical ultrasound, thyroid biopsy, and scintigraphy. The latter revealed elevated thyroid activity. Blood analysis was performed to measure the level of anti-receptor thyroid-stimulating hormone antibodies, which allowed us to test the autoimmune hypothesis. The high level of antibodies together with levels of thyroid-stimulating hormone and the scintigraphy images led to the diagnosis of Grave's disease. Carbimazole treatment followed by thyroidectomy resulted in a quick weight gain and general improvement in health status. The following breeding season, the treated individual sired an offspring. To the authors' knowledge, this is the first report of likely Grave's disease in a non-human primate.

2012-04-01

Tularaemia is a rare arthropod-borne zoonotic infection with 20 to 70 new cases being seen each year in France. Cutaneous ulceration and regional lymphadenopathy are the classical dermatological signs. Diagnosis of atypical forms is more complex. A 48-year-old woman was admitted for an erythematous papular alopecic lesion of the scalp accompanied by fever, chills and cervical lymphadenopathy. Initial antibiotic therapy for 20 days with amoxicillin clavulanate was ineffective. The patient's history included an episode of hunting in the forest three days before the onset of signs. Finally, serology led to the diagnosis of tularaemia. Combined levofloxacin and doxycycline resulted in regression of the scalp lesion and lymph node disorder. The existence of alopecia and location on the scalp did not initially suggest a diagnosis of tularaemia to us. The clinical presentation was highly suggestive of impetigo with satellite lymphadenopathies. However, resistance to antibiotics and the absence of inflammation militated against this diagnosis, and other possible diagnoses such as a tick-borne lymphadenopathy (TIBOLA), borreliosis and tularaemia were discussed. The most common clinical presentation of tularaemia is ulceroglandular tularaemia, which predominates in 80% of cases. The inoculation chancre at the point of initial infection is most often located in the upper limbs. An inflammatory plaque on the scalp with alopecia may reveal tularaemia, a potentially fatal disease resulting from inoculation. Copyright © 2012 Elsevier Masson SAS. All rights reserved.

Frontal fibrosing alopecia treatment options.

PubMed

Fertig, Raymond; Tosti, Antonella

2016-11-01

Frontal fibrosing alopecia (FFA) is a rare dermatologic disease that causes scarring and hair loss and is increasing in prevalence worldwide. FFA patients typically present with hair loss in the frontal scalp region and eyebrows which may be associated with sensations of itching or burning. FFA is a clinically distinct variant of lichen planopilaris (LPP) that affects predominantly postmenopausal women, although men and premenopausal women may also be affected. Early diagnosis and prompt treatment are necessary to prevent definitive scarring and permanent hair loss. Data from retrospective studies indicate that 5-alpha-reductase inhibitors (5aRIs) are effective in stabilizing the disease. In our clinical experience, we have seen optimal results treating FFA patients with oral finasteride in conjunction with hydroxychloroquine, topical calcineurin inhibitors (tacrolimus) and excimer laser in patients with signs of active inflammation.

Lymphocytic mural folliculitis and pancreatic carcinoma in a cat.

Lobetti, Remo

2015-06-01

A 9-year-old castrated domestic shorthair cat was presented with a 6 week history of progressive non-pruritic alopecia, polyphagia and weight loss. A diagnosis of lymphocytic mural folliculitis was made and the cat was treated with a combination of prednisolone and ciclosporin; this produced an improvement in the alopecia but no resolution. Sixteen months after the initial assessment and diagnosis, the cat was re-evaluated for intermittent vomiting and weight loss with normal appetite. On examination the dermatopathy was still evident and a mass involving the duodenum and pancreas was present, which was diagnosed as a pancreatic carcinoma. From this case it would appear that lymphocytic mural folliculitis might be an early dermatological manifestation of pancreatic neoplasia. © ISFM and AAFP 2014.

Neuroactive steroid levels are modified in cerebrospinal fluid and plasma of post-finasteride patients showing persistent sexual side effects and anxious/depressive symptomatology.

Observations performed in a subset of subjects treated with finasteride (an inhibitor of the enzyme 5α-reductase) for male pattern hair loss seem to indicate that sexual dysfunction as well as anxious/depressive symptomatology may occur at the end of the treatment and continue after discontinuation. A possible hypothesis to explain depression symptoms after finasteride treatment might be impairment in the levels of neuroactive steroids. Therefore, neuroactive steroid levels were evaluated in paired plasma and cerebrospinal fluid samples obtained from male patients who received finasteride for the treatment of androgenic alopecia and who, after drug discontinuation, still show long-term sexual side effects as well as anxious/depressive symptomatology. The levels of neuroactive steroids were evaluated by liquid chromatography-tandem mass spectrometry in three postfinasteride patients and compared to those of five healthy controls. Neuroactive steroid levels in plasma and cerebrospinal fluid of postfinasteride patients and healthy controls. At the examination, the three postfinasteride patients reported muscular stiffness, cramps, tremors, and chronic fatigue in the absence of clinical evidence of any muscular disorder or strength reduction. Severity and frequency of the anxious/depressive symptoms were quite variable; overall, all the subjects had a fairly complex and constant neuropsychiatric pattern. Assessment of neuroactive steroid levels in patients showed some interindividual differences. However, the most important finding was the comparison of their neuroactive steroid levels with those of healthy controls. Indeed, decreased levels of tetrahydroprogesterone, isopregnanolone and dihydrotestosterone and increased levels of testosterone and 17β-estradiol were reported in cerebrospinal fluid of postfinasteride patients. Moreover, decreased levels of dihydroprogesterone and increased levels of 5α-androstane-3α,17β-diol and 17β-estradiol were observed in plasma. The present observations confirm that an impairment of neuroactive steroid levels, associated with depression symptoms, is still present in androgenic alopecia patients treated with finasteride despite the discontinuation of the treatment. © 2013 International Society for Sexual Medicine.

Optimized research models are required to further understand the pathogenesis and prophylaxis of chemotherapy-induced alopecia. Our aim was to develop a mouse model for chemotherapy-induced alopecia by follicular unit transplantation of human hair follicles onto immunodeficient mice. Twenty-two weeks after transplantation, a single dose of cyclophosphamide (Cph) was administered to mice in the Cph100 (100 mg/kg) and Cph150 (150 mg/kg) groups. On day 6, hair follicles showed dystrophic changes, with swollen dermal papilla and ectopic melanin clumping in the hair bulb. In addition, upregulated expression of apoptotic regulators [P53, Fas/Fas-ligand, tumor necrosis factor-related apoptosis-inducing ligand/tumor necrosis factor-related apoptosis-inducing ligand receptor (TRAIL/TRAIL receptor), and Bax], increased apoptotic matrix keratinocytes, downregulated Ki67 expression, and decreased melanogenic protein in the hair bulb were noted in both groups. After 12 treatment days, hair follicles in Cph100 mice appeared to diminish dystrophic changes. In contrast, hair follicles of Cph150 mice prematurely entered a dystrophic catagen phase after 9 treatment days, and immunofluorescence staining for Ki67 and melanogenic protein expressions was barely visible. Two hair follicle damage response pathways were observed in this model, namely dystrophic anagen (Cph100) and catagen (Cph150) pathways. Our model might be useful for further understanding the impact of chemotherapy on human hair follicles. Copyright © 2015 The Authors. Published by Elsevier Inc. All rights reserved.

This study aimed to evaluate the effectiveness of a combined set of low level diode laser scanner (665 nm and 808nm) on hair growth, and assessment of safety and effectiveness of a new laser scanner on hair growth treatment procedure in androgenic alopecia. 90 patients (18 to 70 years) with androgenic alopecia were randomized into three groups. The first group (n=30) received 655 nm red light using laser hat, the second group (n=30) received 655 nm red laser plus 808 nm infrared laser using a laser scanner of hair growth device (with the patent number: 77733) and the third group (n=30) received no laser as the control group. Patients in laser scanner group had better results and showed a higher increase in terminal hair density compared with laser hat group (mean of 9.61 versus 9.16 per cm 2 ). We found significant decrease in terminal hair density from baseline in control group (mean -1.8 per cm 2 , p<0.0001). Results showed a statistically significant improvement in the laser scanner of the hair growth group compared with laser hat and the control group. The study showed that treatment with new laser devise had a promising result without any observable adverse effects.

Development and pilot-testing of the Alopecia Areata Assessment Tool (ALTO).

Alopecia areata (AA) is an autoimmune disease characterized by non-scarring hair loss. The lack of a definitive biomarker or formal diagnostic criteria for AA limits our ability to define the epidemiology of the disease. In this study, we developed and tested the Alopecia Areata Assessment Tool (ALTO) in an academic medical center to validate the ability of this questionnaire in identifying AA cases. The ALTO is a novel, self-administered questionnaire consisting of 8 closed-ended questions derived by the Delphi method. This prospective pilot study was administered during a 1-year period in outpatient dermatology clinics. Eligible patients (18 years or older with chief concern of hair loss) were recruited consecutively. No patients declined to participate. The patient's hair loss diagnosis was determined by a board-certified dermatologist. Nine scoring algorithms were created and used to evaluate the accuracy of the ALTO in identifying AA. 239 patients (59 AA cases and 180 non-AA cases) completed the ALTO and were included for analysis. Algorithm 5 demonstrated the highest sensitivity (89.8%) while algorithm 3 demonstrated the highest specificity (97.8%). Select questions were also effective in clarifying disease phenotype. In this study. we have successfully demonstrated that ALTO is a simple tool capable of discriminating AA from other types of hair loss. The ALTO may be useful to identify individuals with AA within large populations.

Androgens and alopecia.

PubMed

Kaufman, Keith D

2002-12-30

Androgens have profound effects on scalp and body hair in humans. Scalp hair grows constitutively in the absence of androgens, while body hair growth is dependent on the action of androgens. Androgenetic alopecia, referred to as male pattern hair loss (MPHL) in men and female pattern hair loss (FPHL) in women, is due to the progressive miniaturization of scalp hair. Observations in both eunuchs, who have low levels of testicular androgens, and males with genetic 5alpha-reductase (5alphaR) deficiency, who have low levels of dihydrotestosterone (DHT), implicate DHT as a key androgen in the pathogenesis of MPHL in men. The development of finasteride, a type 2-selective 5alphaR inhibitor, further advanced our understanding of the role of DHT in the pathophysiology of scalp alopecia. Controlled clinical trials with finasteride demonstrated improvements in scalp hair growth in treated men associated with reductions in scalp DHT content, and a trend towards reversal of scalp hair miniaturization was evident by histopathologic evaluation of scalp biopsies. In contrast to its beneficial effects in men, finasteride did not improve hair growth in postmenopausal women with FPHL. Histopathological evaluation of scalp biopsies confirmed that finasteride treatment produced no benefit on scalp hair in these women. These findings suggest that MPHL and FPHL are distinct clinical entities, with disparate pathophysiologies. Studies that elucidate the molecular mechanisms by which androgens regulate hair growth would provide greater understanding of these differences. Copyright 2002 Elsevier Science Ireland Ltd.

The Role of Lymphocytes in the Development and Treatment of Alopecia Areata

PubMed Central

Guo, Hongwei; Cheng, Yabin; Shapiro, Jerry; McElwee, Kevin

2016-01-01

Summary Alopecia areata (AA) development is associated with both innate and adaptive immune cell activation, migration to peri-and intra-follicular regions, and hair follicle disruption. Both CD4+ and CD8+ lymphocytes are abundant in AA lesions; however, CD8+ cytotoxic T lymphocytes are more likely to enter inside hair follicles, circumstantially suggesting that they have a significant role to play in AA development. Several rodent models recapitulate important features of the human autoimmune disease and demonstrate that CD8+ cytotoxic T lymphocytes are fundamentally required for AA induction and perpetuation. However, the initiating events, the self-antigens involved, and the molecular signaling pathways, all need further exploration. Studying CD8+ cytotoxic T lymphocytes and their fate decisions in AA development may reveal new and improved treatment approaches. PMID:26548356

Immunofluorescence findings in rapid whitening of scalp hair.

PubMed

Guin, J D; Kumar, V; Petersen, B H

1981-09-01

Rapid whitening of scalp hair developed during a three-month period along with a diffuse, subtotal alopecia in a patient. Immunofluorescence microscopy of biopsy material showed prominent deposits of IgG and IgM in a granular pattern in the epithelium of the lower portions of hair follicles. Some return of the color and amount of scalp hair occurred within a year, but occasional bouts of hair loss continued to occur. It is theorized that the rapid graying was caused by a selective loss of pigmented hair, which was perhaps caused by an immunologic mechanism. Some of the findings suggest that the cause of this patient's loss of hair color may be different from those of patients who have been previously described as having rapid whitening of scalp hair because of alopecia areata or vitiligo.

Aggressive periodontitis in a patient with chronic cutaneous lupus erythematosus: a case report.

PubMed

Tietmann, Christina; Bissada, Nabil F

2006-05-01

Lupus erythematosus is considered to be a high risk factor for periodontitis. As an autoimmune disease of unknown origin, cutaneous lupus erythematosus (CLE) is subdivided into 3 categories: chronic (CCLE), subacute (SCLE), and acute (ACLE). While the ACLE has a high prevalence of conjunctive periodontal lesions, aggressive periodontitis in patients with CCLE has been rarely reported. This article describes the case of a patient diagnosed with aggressive periodontitis. Three months after the diagnosis of periodontitis, the patient experienced advancing hair loss (alopecia), pale fingers and toes, as well as edema in the legs and around the eyes. Skin biopsy showed follicular hyperkeratosis with perivascular mononuclear cell infiltrate. Colliquation of the basal cells, thickening of the basal lamina, and vacuolar degeneration of basal keratinocytes were also found. A lupus band test was positive, and diagnosis of CCLE was established. Three months following the treatment of lupus with antimalarial agents, the periodontal condition became stable with no further exacerbation or progression of the existing periodontitis. An 11-month postsurgical follow-up revealed stable periodontal and general medical conditions. A patient's medical history should be re-evaluated in the event of recurrence of periodontal lesions refractory to periodontal treatment. The control of systemic conditions like lupus erythematosus is essential for a good prognosis in the treatment of periodontitis as well as for the general health of the patient.

How to Reach Emotions with Psychosomatic Patients: A Case Report.

PubMed

Colaianni, Gwenaëlle; Poot, Francoise

Alopecia areata (patchy hairloss) often indicates to the dermatologist the existence of psychological disorders, mostly anxiety and depression. Psychosomatic conditions are usually associated with difficulty in expressing emotions, as is the case in alexithymia, and this difficulty is often seen in patients with alopecia areata. This case study aims to show how to help these patients connect with their emotions and how the somatic symptom can become meaningful by using a unifying approach, which challenges the beliefs, the rules and the interactions of both the individual and the family, as well as the emotions expressed or suppressed. In this particular case we used a systemic family therapy tool, "the family blazon" that helped to discover the unconscious myth of unity and the fear of family disaggregation that is involved in psychosomatic families.

2015-03-01

Corneal epithelial dysfunction ( CED ) is the abnormality of the regeneration, conjunction, adhesion and immigration of the corneal epithelium cells without the decompensation of the corneal limbal cells. Due to the affection resulting from the systemic problems of patients and the management in the preoperative period, some of the patients at one to two weeks after cataract surgery will present the edema and fluorescein staining of the corneal epithelium. Without correct therapy, the defect of the epithelium, or even persisting ulceration of the cornea will occur. The key points of the management for CED are the early diagnosis and reasonable therapy. We suggest paying special attention to CED in the patients with metabolism diseases, abnormality of the tear film and long-term blepharitis.

The purpose of this study was to investigate the tolerability and intraocular pressure (IOP) reducing effect of the first preservative-free prostaglandin tafluprost (Taflotan) in patients exhibiting ocular surface side-effects during latanoprost (Xalatan) treatment. A total of 158 patients were enrolled in this open-label multicentre study. Eligible patients had to have at least two ocular symptoms, or one sign and one symptom, during treatment with latanoprost. At baseline, the patients were directly switched from latanoprost to preservative-free tafluprost for 12 weeks. The patients were queried for ocular symptoms, and ocular signs were assessed by using tear break-up time, Schirmer's test, fluorescein staining and evaluation of conjunctival hyperaemia and blepharitis. In addition, HLA-DR and MUC5AC in conjunctival impression cytology specimens were analyzed, and a drop discomfort/quality of life (QoL) questionnaire was employed. IOP was measured at all visits. Preservative-free tafluprost maintained IOP at the same level after 12- weeks treatment (16.4 +/- 2.7 mmHg) as latanoprost at baseline (16.8 +/- 2.5 mmHg). During treatment with preservative-free tafluprost, the number of patients having irritation/burning/stinging (56.3%), itching (46.8%), foreign body sensation (49.4%), tearing (55.1%) and dry eye sensation (64.6%) decreased to 28.4%, 26.5%, 27.1%, 27.1% and 39.4% correspondingly. The number of the patients with abnormal fluorescein staining of cornea (81.6%) and conjunctiva (84.2%), blepharitis (60.1%), conjunctival hyperaemia (84.2%) and abnormal Schirmer's test (71.5%) was also reduced significantly to 40.6%, 43.2%, 40.6%, 60.0% and 59.4% correspondingly. The tear break-up time improved significantly from 4.5 +/- 2.5 seconds to 7.8 +/- 4.9 seconds. A reduction in the number of patients with abnormal conjunctival cells based on HLA-DR and MUC5AC was also detected. Preservative-free tafluprost maintained IOP at the same level as latanoprost, but was better tolerated in patients having signs or symptoms while on preserved latanoprost. Preservative-free tafluprost treatment resulted in improved QoL, increased patient satisfaction and drop comfort.

This study developed lipid nanocarriers, called squarticles, conjugated with anti-platelet-derived growth factor (PDGF)-receptor β antibody to determine whether targeted Minoxidil (MXD) delivery to the follicles and dermal papilla cells (DPCs) could be achieved. Squalene and hexadecyl palmitate (HP) were used as the matrix of the squarticles. The PDGF-squarticles showed a mean diameter and zeta potential of 195 nm and -46 mV, respectively. Nanoparticle encapsulation enhanced MXD porcine skin deposition from 0.11 to 0.23 μg/mg. The antibody-conjugated nanoparticles ameliorated follicular uptake of MXD by 3-fold compared to that of the control solution in the in vivo mouse model. Both vertical and horizontal skin sections exhibited a wide distribution of nanoparticles in the follicles, epidermis, and deeper skin strata. The encapsulated MXD moderately elicited proliferation of DPCs and vascular endothelial growth factor (VEGF) expression. The active targeting of PDGF-squarticles may be advantageous to improving the limited success of alopecia therapy. Topical use of minoxidil is only one of the very few treatment options for alopecia. Nonetheless, the current delivery method is far from ideal. In this article, the authors developed lipid nanocarriers with anti-platelet-derived growth factor receptor ? antibody to target dermal papilla cells, and showed enhanced uptake of minoxidil.

Male androgenetic alopecia (AGA) is the most common form of hair loss in men. It is characterized by a distinct pattern of progressive hair loss starting from the frontal area and the vertex of the scalp. Although several genetic risk loci have been identified, relevant genes for AGA remain to be defined. To identify biomarkers associated with AGA. Molecular biomarkers associated with premature AGA were identified through gene expression analysis using cDNA generated from scalp vertex biopsies of hairless or bald men with premature AGA, and healthy volunteers. This monocentric study reveals that genes encoding mast cell granule enzymes, inflammatory mediators and immunoglobulin-associated immune mediators were significantly overexpressed in AGA. In contrast, underexpressed genes appear to be associated with the Wnt/β-catenin and bone morphogenic protein/transforming growth factor-β signalling pathways. Although involvement of these pathways in hair follicle regeneration is well described, functional interpretation of the transcriptomic data highlights different events that account for their inhibition. In particular, one of these events depends on the dysregulated expression of proopiomelanocortin, as confirmed by polymerase chain reaction and immunohistochemistry. In addition, lower expression of CYP27B1 in patients with AGA supports the notion that changes in vitamin D metabolism contributes to hair loss. This study provides compelling evidence for distinct molecular events contributing to alopecia that may pave the way for new therapeutic approaches. © 2017 British Association of Dermatologists.

Clinical utility and validity of minoxidil response testing in androgenetic alopecia.

Clinical response to 5% topical minoxidil for the treatment of androgenetic alopecia (AGA) is typically observed after 3-6 months. Approximately 40% of patients will regrow hair. Given the prolonged treatment time required to elicit a response, a diagnostic test for ruling out nonresponders would have significant clinical utility. Two studies have previously reported that sulfotransferase enzyme activity in plucked hair follicles predicts a patient's response to topical minoxidil therapy. The aim of this study was to assess the clinical utility and validity of minoxidil response testing. In this communication, the present authors conducted an analysis of completed and ongoing studies of minoxidil response testing. The analysis confirmed the clinical utility of a sulfotransferase enzyme test in successfully ruling out 95.9% of nonresponders to topical minoxidil for the treatment of AGA. © 2014 Wiley Periodicals, Inc.

Cutaneous discoloration secondary to dermal deposition of titanium dioxide (TiO2) particles is recognized but seldom reported in the literature. In this report, the authors describe the case of a 61-year-old gentleman, with a long history of alopecia areata, who presented with numerous, discrete dark blue macules on the scalp. Scanning electron microscopy with energy dispersive x-ray spectroscopy analysis ultimately identified the macules as deposits of TiO2. The patient had a history of intralesional triamcinolone injections for management of alopecia areata. A sample of generic 0.1% triamcinolone acetonide paste was analyzed and found to contain many TiO2 particles analogous to those seen in the patient's biopsy sample. To the authors' knowledge, this is the first reported case of TiO2 deposition in the dermis likely resulting from topical combined with intralesional triamcinolone injection.

The management of hair and scalp conditions is difficult in any patient, especially given the emotional and psychological implications of hair loss. This undertaking becomes even more challenging in the ethnic patient. Differences in hair care practices, hair shaft morphology, and follicular architecture add complexity to the task. It is imperative that the physician be knowledgeable about these practices and the phenotypic differences seen in ethnic hair in order to appropriately diagnose and treat these patients. In this chapter, we will discuss cultural practices and morphologic differences and explain how these relate to the specific disorders seen in ethnic populations. We will also review the most prominent of the ethnic hair conditions including acquired trichorrhexis nodosa, traction alopecia, central centrifugal cicatricial alopecia, pseudofolliculitis barbae, dissecting cellulitis, and acne keloidalis nuchae. © 2015 S.

To examine outbreaks of mange in raccoon dogs (Nyctereutes procyonoides) with respect to population density, we analyzed camera trap videos, and isolated mites from raccoon dog carcasses. In a camera trapping survey, we categorized the skin condition of raccoon dogs, and used a number of independent videos to calculate the relative abundance index (RAI). The RAI of raccoon dogs with alopecia increased following an increase in the RAI of those without alopecia. Among 27 raccoon dog carcasses, 12 showed mange-compatible skin lesions. Sarcoptes scabiei was isolated from 11 of these raccoon dogs, indicating that sarcoptic mange was endemic in our study area. Therefore, a high relative population density may be a factor underlying epizootics of sarcoptic mange in raccoon dogs. PMID:29353863

CD8+ T-Cell Deficiency, Epstein-Barr Virus Infection, Vitamin D Deficiency, and Steps to Autoimmunity: A Unifying Hypothesis.

PubMed

Pender, Michael P

2012-01-01

CD8+ T-cell deficiency is a feature of many chronic autoimmune diseases, including multiple sclerosis, rheumatoid arthritis, systemic lupus erythematosus, Sjögren's syndrome, systemic sclerosis, dermatomyositis, primary biliary cirrhosis, primary sclerosing cholangitis, ulcerative colitis, Crohn's disease, psoriasis, vitiligo, bullous pemphigoid, alopecia areata, idiopathic dilated cardiomyopathy, type 1 diabetes mellitus, Graves' disease, Hashimoto's thyroiditis, myasthenia gravis, IgA nephropathy, membranous nephropathy, and pernicious anaemia. It also occurs in healthy blood relatives of patients with autoimmune diseases, suggesting it is genetically determined. Here it is proposed that this CD8+ T-cell deficiency underlies the development of chronic autoimmune diseases by impairing CD8+ T-cell control of Epstein-Barr virus (EBV) infection, with the result that EBV-infected autoreactive B cells accumulate in the target organ where they produce pathogenic autoantibodies and provide costimulatory survival signals to autoreactive T cells which would otherwise die in the target organ by activation-induced apoptosis. Autoimmunity is postulated to evolve in the following steps: (1) CD8+ T-cell deficiency, (2) primary EBV infection, (3) decreased CD8+ T-cell control of EBV, (4) increased EBV load and increased anti-EBV antibodies, (5) EBV infection in the target organ, (6) clonal expansion of EBV-infected autoreactive B cells in the target organ, (7) infiltration of autoreactive T cells into the target organ, and (8) development of ectopic lymphoid follicles in the target organ. It is also proposed that deprivation of sunlight and vitamin D at higher latitudes facilitates the development of autoimmune diseases by aggravating the CD8+ T-cell deficiency and thereby further impairing control of EBV. The hypothesis makes predictions which can be tested, including the prevention and successful treatment of chronic autoimmune diseases by controlling EBV infection.

Anger plays a major role in psychodermatological diseases. Researchers have reported that anger and other psychological factors play a role in the etiology of chronic urticaria. This study aimed to examine symptoms of anger, anger-related behavioral patterns, thoughts associated with anger, situations that cause anger and experiences of interpersonal anger in patients with chronic spontaneous urticaria (CSU). The authors hypothesized that patients with CSU react to more situations with anger and experience more anger symptoms as compared to alopecia areata (AA) patients and healthy controls. The cohort study population consisted of literate adult patients aged <65 years that were diagnosed with CSU at the outpatient dermatology clinics of Başkent and Gazi University, Ankara, Turkey, between September 2011 and October 2012. The first control group included individuals without any physical or mental disorders and the second one included literate adult patients diagnosed with AA. The patients and controls were matched according to age, gender, and level of education. A sociodemographic data form, and the Hospital Anxiety and Depression Scale and Multi-Dimensional Anger Inventory were administered to the participants. Data were analyzed using SPSS v.17.0 for Windows. The primary outcome was to determine whether there was a relationship between anger and CSU. The CSU group consisted of 30 participants; AA group consisted of 30 participants; and the healthy group consisted of 39 participants. Anxiety and depression scores in the CSU group were significantly higher than those in the healthy control group. Symptoms of anger, situations that cause anger, and thoughts associated with anger were significantly more common in the CSU group compared to AA group and healthy group. More of the CSU patients were observed to respond with excessive anger to most situations, to have high levels of anxiety anger and passive aggressive interpersonal relationships.

Koebner phenomenon in alopecia areata: rapid appearance after trichogram. Implications for the pathogenesis and therapy.

PubMed

D'Ovidio, R

2013-04-01

Anecdotical experiences indicate that Koebner phenomenon (KP) can also be observed in alopecia areata (AA). The present short report gives an account of what has been observed in some patients with remitting-relapsing AA in multiple patches, in whom the phenomenon was accidentally caused by perilesional Trichogram. The almost immediate appearance of relapses of the disease (1-7 days) and their evolution can be useful to understand the physiopathology of AA and and emphasize the compelling need for a rapid and appropriate diagnosis and treatment in the acute phase of AA, even with the active participation of the patient adequately trained. The method of trichogram should be reserved for cases in which non-invasive methods such as the Pull Test or Trichoscopy are not sufficient to verify the activity of the disease.

2017-12-01

An adult male Ruwenzori long-haired fruit bat ( Rousettus lanosus) presented for lethargy and unthriftiness. Physical examination revealed cranial alopecia, mandibular ulceration, and dehydration. Supportive care and antibiotic therapy were initiated. The bat was found dead 3 days after presentation. Necropsy revealed alopecia on the head and body, exposed dried bone on the rostral tip of the mandible, and excessive clear pleural fluid. Lungs were congested and contained miliary white foci disseminated randomly throughout the parenchyma. Subcutaneous, intra-thoracic, and intra-abdominal adipose depots were minimal. Histologic examination of skin and lung revealed the presence of algal-like organisms morphologically consistent with Prototheca spp. Polymerase chain reaction amplification revealed >99% sequence identity match with Prototheca zopfii. Protothecosis has been previously reported in a single bat, Lyle's flying fox ( Pteropus lylei), in Switzerland, but definitive protothecal speciation was not possible.

Alopecia areata (AA) is a common autoimmune disease that presents with non-scarring alopecia. It is characterized by intra- or peri-follicular lymphocytic infiltrates composed of CD4+ and CD8+ T-cells on histology. To this day, few treatments are effective for AA. Here we present findings of using a low-level laser comb to alleviate the symptoms of AA in a C3H/HeJ mouse model for AA. Fourteen C3H/HeJ mice with induced AA were used in this study. Two were killed to confirm AA through histology. The remaining 12 mice were randomized into two groups; group I received HairMax LaserComb (wavelength: 655 nm, beam diameter <5 mm; divergence 57 mrad; nine lasers) for 20 s daily, three times per week for a total of 6 weeks; group II was treated similarly, except that the laser was turned off (sham-treated). After 6 weeks of LaserComb treatment, hair regrowth was observed in all the mice in group I (laser-treated) but none in group II (sham-treated). On histology, increased number of anagen hair follicles was observed in laser-treated mice. On the other hand, sham-treated mice demonstrated hair follicles in the telogen phase with no hair shaft. LaserComb seems to be an effective and convenient device for the treatment of AA in the C3H/HeJ mouse model. Human studies are required to determine the efficacy and safety of this device for AA therapy.

Alopecia is one of the most distressing side effects of chemotherapy. Evaluating and comparing the efficacy of potential therapies to prevent chemotherapy-induced alopecia (CIA) has been complicated by the lack of a standardized measurement for hair loss. In this study we investigated the correlation between patient-reported outcome assessments and quantitative measurement with the hair check to assess CIA in clinical practice. Scalp cooling efficacy was evaluated by patients by World Health Organisation (WHO) of CIA, Visual Analogue Scale (VAS) and wig use. The Hair Check was used to determine the amount of hair (in mm 2 ) per unit of scalp skin area (in cm 2 ) (Hair Mass Index, HMI). CIA was also evaluated by doctors, nurses and hairdressers. Baseline HMI was not predictive for hair loss. HMI declined throughout all chemotherapy cycles, which was not reflected by patient-reported measures. HMI correlated with patient-reported hair quantity before the start of the therapy, but not with WHO and/or VAS during therapy. Patient's opinion correlated moderately with the opinion of doctors and nurses (ρ = 0.50-0.56 respectively), but strongly with hair dressers (ρ = 0.70). The Hair check is suitable to quantify the amount of hair loss and could complement research on refining outcome of scalp cooling, but the patient's opinion should be considered as the best method to assess hair loss in clinical practice.

Acne keloidalis nuchae (AKN) is a chronic inflammatory disease involving hair follicles of the neck. It is a form of keloidal scarring alopecia that is often refractory to medical or surgical management. To evaluate the efficacy of Er:YAG laser in the treatment of AKN as compared to long pulsed Nd:YAG laser. This study was conducted on 30 male patients with AKN. Their ages ranged from 19 to 47 years with a mean age of 36.87 ± 7.8 years. Patients were divided randomly into two groups of 15 patients, each receiving six sessions of either Er:YAG or long-pulsed Nd:YAG laser therapy. A statistically significant decrease in the number of papules was detected at the end of therapy in both groups, with a mean of 91.8% improvement in the Er:YAG group versus 88% in the Nd:YAG group. A significant decrease in plaques count was detected only in the Er: YAG group while a significant decrease in plaques size and consistency was recorded in both groups. The Er: YAG laser proved to be a potentially effective and safe modality both in the early and late AKN lesions.

Chronic graft-versus-host disease (cGVHD) is an increasingly frequent complication of allogeneic stem cell transplantation. Current therapies for cGVHD reduce symptoms but are not cures. The B10.D2-->Balb/c (H-2(d)) minor histocompatibility antigen-mismatched model, which reflects clinical and pathological symptoms of human cGVHD, was used in this study. We demonstrated that a single injection of an agonistic monoclonal antibody (mAb) against CD137, a member of the tumor necrosis factor receptor superfamily, reverses skin fibrosis, ulceration, and alopecia, a dominant feature of cGVHD (cutaneous GVHD), ultimately improving general health conditions. The reversal is associated with markedly reduced CD4(+) T-cell cytokines and increased apoptosis of donor CD4(+) T cells. The Fas pathway is required for ameliorating cutaneous GVHD by anti-CD137 mAb. Taken together, these data indicate that the anti-CD137 mAb has a therapeutic effect on cutaneous GVHD by removing donor CD4(+) T cells that cause cutaneous GVHD. Thus, our study demonstrates an agonistic mAb, specific for a costimulatory molecule, as a possible target for therapeutic intervention in cutaneous GVHD.

We tested the significance of psychic factors in the etiology of alopecia areata by means of the assessment of the Behaviour Pattern A (BPA)--a particular way of regulation of the relations between the individual and the environment, the basis of which is a great need for achievement in the individual who realizes this need by means of domination and aggressiveness. The testing was carried out by means of the Polish Questionnaire for the Assessment of the Behaviour Pattern A in adults. 60 patients were tested (31 women and 29 men). The results were compared with the normative groups described by Wrześniewski. The frequency of the occurrence of the Behaviour Pattern A in the tested patients may indicate the connection of this type of regulation of relations between the individual and the environment with the susceptibility to this disease.

Alopecia due to an allergic reaction to metal head-pins used in a neurosurgical operation.

Allergic reactions to the metal head-pins of a head fixation holder are rare. A 45-year-old woman was referred to our hospital for the treatment of unruptured cerebral aneurysms. She underwent successful surgical treatment using four head-pins of the Sugita frame. At her first outpatient visit 3 weeks after discharge, redness, sores, and focal hair loss were noted at all four areas where the pinning had been performed. The pin fixation was considered to be responsible for the alopecia because the condition of the scalp lesions was even in all four parts. Six months later, the scalp regained hair. The head-pins were made of stainless steel, containing iron, nickel, chromium, and other components. A previous history of contact dermatitis to metal jewellery was later proven. The history of metal allergy should have been carefully elicited because head fixation with head-pins is essential for neurosurgical procedures.

Based on previous findings, from a worldwide study, classified the shapes of human hair into 8 major types, from straight to highly curly. This clearly extended the usual classification of hair into African, Asian or Caucasian types. However, determinations of hair growth parameters and hair density were excluded from such studies. To measure and compare the hair growth profiles of young adults without alopecia living in the five continents. 2249 young adults (18-35 years, females and males) without alopecia, originating from 24 various human ethnic groups were included in the study. Total hair density, telogen percentage and growth rate on three different scalp areas were measured, using non-invasive validated techniques. Natural hair colour level, curliness and hair diameter were additionally recorded, when practically possible. Diversity in hair growth parameters among the entire cohort was a key finding, with differences linked to scalp area, gender and geographic origin. Statistical approaches depicted African hair as having lower density and a slower growth rate. Asian hair showed a thicker diameter, with faster growth. Caucasian hair showed a high total hair density. On the one hand, this inter-continental study of hair growth parameters provides initial valuable base-line data on hair in young adults without alopecia, and on the other hand, further extends our knowledge of this unique human appendage, with some mosaic features, observed worldwide.

Although the genetic basis of androgenic alopecia has been clearly established, little is known about its non-genetic causes, such as environmental and lifestyle factors. This study investigated blood and urine heavy metals concentrations, environmental exposure factors, personal behaviors, dietary intakes and the genotypes of related susceptibility genes in patients with androgenic alopecia (AGA). Age, AGA level, residence area, work hours, sleep patterns, cigarette usage, alcohol consumption, betel nut usage, hair treatments, eating habits, body heavy metals concentrations and rs1998076, rs913063, rs1160312 and rs201571 SNP genotype data were collected from 354 men. Logistic regression analysis was performed to examine whether any of the factors displayed odds ratios (ORs) indicating association with moderate to severe AGA (≥ IV). Subsequently, Hosmer-Lemeshow, Nagelkerke R(2) and accuracy tests were conducted to help establish an optimal model. Moderate to severe AGA was associated with the AA genotype of rs1160312 (22.50, 95% CI 3.99-126.83), blood vanadium concentration (0.02, 95% CI 0.01-0.04), and regular consumption of soy bean drinks (0.23, 95% CI 0.06-0.85), after adjustment for age. The results were corroborated by the Hosmer-Lemeshow test (P = 0.73), Nagelkerke R(2) (0.59), accuracy test (0.816) and area under the curve (AUC; 0.90, 0.847-0.951) analysis. Blood vanadium and frequent soy bean drink consumption may provide protect effects against AGA. Accordingly, blood vanadium concentrations, the AA genotype of rs1160312 and frequent consumption of soy bean drinks are associated with AGA.

Alopecia areata (AA), which appears as nonscarring hair shedding on any hair-bearing area, is a common organ-specific autoimmune condition. Cytokines have important roles in the development of AA. Interleukin (IL) 18 is a significant proinflammatory cytokine that was found higher in the patients with AA. We aimed to investigate whether the IL-18 (rs187238 and rs1946518) single nucleotide polymorphisms (SNPs) may be associated with AA and/or clinical outcome of patients with AA in Turkish population. Genotyping of rs187238 and rs1946518 SNPs were detected using sequence-specific primer-polymerase chain reaction (SSP-PCR) method in 200 patients with AA and 200 control subjects. The genotype distribution of rs1946518 (-607C>A) SNP was found to be statistically significantly different among patients with AA and controls (P = .0008). Distribution of CC+CA genotypes and frequency of -607/allele C of rs1946518 SNP were higher in patients with AA (P = .001, P = .001, respectively). The genotype distribution of rs187238 (-137G>C) SNP was found to be statistically significantly different among patients with AA and control subjects (P = .0014). Distribution of GG genotype and frequency of -137/allele G of rs187238 SNP were higher in patients with AA (P = .0003, P = .001, respectively). The rs1946518 (-607C>A) and rs187238 (-137G>C) polymorphisms were found associated with alopecia areata disease. The study suggests that IL-18 rs187238 and rs1946518 SNPs may be the cause of the AA susceptibility. © 2018 Wiley Periodicals, Inc.

PAK1 (p21-activated kinase 1) is an emerging target for the treatment of hair loss (alopecia) and cancer; therefore, the search for PAK1 blockers to treat these PAK1-dependent disorders has received much attention. In this study, we evaluated the anti-alopecia and anticancer effects of PAK1 inhibitors isolated from Alpinia zerumbet (alpinia) in cell culture. The bioactive compounds isolated from alpinia were found to markedly promote hair cell growth. Kaempferol-3- O -β-d-glucuronide (KOG) and labdadiene, two of the isolated compounds, increased the proliferation of human follicle dermal papilla cells by approximately 117%-180% and 132%-226%, respectively, at 10-100 μM. MTD (2,5-bis(1 E ,3 E ,5 E )-6-methoxyhexa-1,3,5-trien-1-yl)-2,5-dihydrofuran) and TMOQ (( E )-2,2,3,3-tetramethyl-8-methylene-7-(oct-6-en-1-yl)octahydro-1 H -quinolizine) showed growth-promoting activity around 164% and 139% at 10 μM, respectively. The hair cell proliferation induced by these compounds was significantly higher than that of minoxidil, a commercially available treatment for hair loss. Furthermore, the isolated compounds from alpinia exhibited anticancer activity against A549 lung cancer cells with IC 50 in the range of 67-99 μM. Regarding the mechanism underlying their action, we hypothesized that the anti-alopecia and anticancer activities of these compounds could be attributed to the inhibition of the oncogenic/aging kinase PAK1.

Objective To determine the clinical manifestations and disease damage associated with discoid rash in a large multiethnic systemic lupus erythematosus (SLE) cohort. Methods SLE patients (per ACR criteria), age ≥ 16 years, disease duration ≤ 10 years at enrollment, and defined ethnicity (African American, Hispanic or Caucasian), from a longitudinal cohort were studied. Socioeconomic-demographic features, clinical manifestations and disease damage [as per the Systemic Lupus International Collaborating Clinics Damage Index (SDI)] were determined. The association of DLE with clinical manifestations and disease damage was examined using multivariable logistic regression. Results A total of 2,228 SLE patients were studied. The mean (standard deviation, SD) age at diagnosis was 34.3 (12.8) years and the mean (SD) disease duration was 7.9 (6.0) years; 91.8% were women. Discoid lupus was observed in 393 (17.6%) of patients with SLE. In the multivariable analysis, patients with discoid lupus were more likely to be smokers and of African-American ethnicity, and to have malar rash, photosensitivity, oral ulcers, leukopenia and vasculitis. DLE patients were less likely to be of Hispanic (from Texas) ethnicity, and to have arthritis, end-stage renal disease (ESRD), and antinuclear, anti-dsDNA and anti-phospholipid antibodies. Patients with DLE had more damage accrual, particularly chronic seizures, scarring alopecia, scarring of the skin, and skin ulcers. Conclusion In this cohort of SLE patients, discoid lupus was associated with several clinical features including serious manifestations such as vasculitis and chronic seizures. PMID:22190480

2000-01-01

Thyroid function was assessed in euthyroid dogs (n = 20), dogs suffering from canine recurrent flank alopecia (CRFA, n = 18), and hypothyroid dogs (n = 21). Blood samples obtained from all dogs in each group were assayed for total thyroxine (TT4), thyrotropin (TSH), and thyroglobulin autoantibody (TgAA) serum concentrations. Total T4 and TSH serum concentrations were significantly decreased and increased, respectively, in the hypothyroid group compared with the other 2 groups. No significant differences in TT4 and TSH serum values were found between the euthyroid and CRFA groups. Thyroglobulin autoantibodies were detected in 10, 11.1, and 61.9% of euthyroid dogs, dogs with CRFA, and hypothyroid dogs, respectively. In conclusion, dogs suffering from CRFA have a normal thyroid function, and the determination of TT4 and TSH serum concentrations allows differentiation of these dogs from dogs with hypothyroidism, in most cases. Occasionally, the 2 diseases can be concomitant. PMID:10992988

Keratin 17 null mice exhibit age- and strain-dependent alopecia.

Onset of type I keratin 17 (K17) synthesis marks the adoption of an appendageal fate within embryonic ectoderm, and its expression persists in specific cell types within mature hair, glands, and nail. We report that K17 null mice develop severe alopecia during the first week postbirth, correlating with hair fragility, alterations in follicular histology, and apoptosis in matrix cells. These alterations are incompletely penetrant and normalize starting with the first postnatal cycle. Absence of a hair phenotype correlates with a genetic strain-dependent compensation by related keratins, including K16. These findings reveal a crucial role for K17 in the structural integrity of the first hair produced and the survival of hair-producing cells. Given that identical inherited mutations in this gene can cause either pachyonychia congenita or steatocystoma multiplex, the features of this mouse model suggest that this clinical heterogeneity arises from a cell type-specific, genetically determined compensation by related keratins.

Ascorbigen induces dermal papilla cell proliferation in vitro, but fails to modulate chemotherapy-induced alopecia in vivo.

PubMed

Ascorbigen (ABG) is the predominant indole-derived compound from Brassica vegetables. In this study, we attempted to evaluate the effects of ABG on hair growth. To this end, we examined the proliferation of isolated human dermal papilla (DP) cells and keratinocytes after incubation in various concentrations (0-1.25 mM) of ABG. Furthermore, hair shaft regrowth was monitored in a mouse model of chemotherapy-induced alopecia (CIA), and hematoxylin and eosin staining was performed for histological analyses. We found that 1.25 mM ABG induced a 1.2-fold increase in the growth of DP cells, but not keratinocytes. However, ABG did not exert significant protective effects against CIA in the mouse model. These findings suggest that ABG may not be able to counteract CIA and that further investigation of the therapeutic potential of ABG in disease models is required.

Platelet-rich plasma-an 'Elixir' for treatment of alopecia: personal experience on 117 patients with review of literature.

PubMed

Garg, Suruchi; Manchanda, Shweta

2017-01-01

Platelet-rich plasma (PRP) has emerged as a new treatment modality in regenerative plastic surgery and dermatology. PRP is a simple, cost-effective and feasible treatment option with high patient satisfaction for hair loss and can be regarded as a valuable adjuvant treatment modality for androgenic alopecia and other types of non-scarring alopecias. Authors have proposed a hair model termed "Golden anchorage with 'molecular locking' of ectodermal and mesenchymal components for survival and integrity of hair follicle (HF)" in this article. Golden anchorage comprises of bulge stem cells, ectodermal basement membrane and bulge portion of APM. PRP with its autologous supply of millions of growth factors works on 'Golden anchorage' along with keratinocytes (PDGF), dermal papilla (IGF and fibroblast growth factor), vasculature (VEGF and PDGF) and neural cells (Nerve Growth Factor) in a multipronged manner serving as an 'elixir' for hair growth and improving overall environment.

Androgenetic alopecia, also known as male and female pattern hair loss, is a very prevalent condition; however, approved therapeutic options are limited. Fractionated laser has been proposed to assist in penetration of topical medications to the cutaneous tissue. We present four cases of androgenetic alopecia that underwent treatment with a non-ablative erbium glass fractional laser followed by the application of topical finasteride 0,05% and growth factors including basic fibroblast growth factor, insulin-like growth factor, vascular endothelial growth factor, and copper peptide 1%. During all laser treatment sessions, eight passes were performed, at 7 mJ, 3-9% of coverage and density of 120 mzt/cm 2 . A positive response was observed in all of the four patients. Photographs taken 2 weeks after the last session showed improvement in hair regrowth and density. No significant side effects were observed.

A case report of coup de sabre patient with hair transplantation.

Treatment of coup de sabre must remain conservative until the disease is no longer in an active state. When activity has ceased, some operative intervention is safe and effective for the correction of deformity. While hair transplantation showed high survival rates for the correction of cicatricial alopecia, it has rarely reported to be performed for the correction of coup de sabre. To assess the therapeutic possibility of hair transplantation for the correction of coup de sabre. Follicular units consisting of two to three hairs from the patient's occipital scalp were transplanted and followed-up for 12 months. After 12 months of follow-up, treatment outcomes showed an 86.7% survival rate and 12-16 cm (mean 14 cm) length of the transplanted hairs. When coup de sabre is no longer in an active state, hair transplantation is a useful method for cosmetic improvement of the alopecia.

Populations of wildlife species worldwide experience incidents of mass morbidity and mortality. Primary or secondary drivers of these events may escape classical detection methods for identifying microbial insults, toxin exposure, or additional stressors. In 2012, 28% of polar bears sampled in a study in the southern Beaufort Sea region of Alaska had varying degrees of alopecia that was concomitant with reduced body condition. Concurrently, elevated numbers of sick or dead ringed seals were detected in the southern Beaufort, Chukchi, and Bering seas in 2012, resulting in the declaration of an unusual mortality event (UME) by the National Oceanic and Atmospheric Administration (NOAA). The primary and possible ancillary causative stressors of these events are unknown, and related physiological changes within individual animals have been undetectable using classical diagnostic methods. Here we present an emerging technology as a potentially guiding investigative approach aimed at elucidating the circumstances responsible for the susceptibility of certain polar bears to observed conditions. Using transcriptomic analysis we identified enhanced biological processes including immune response, viral defense, and response to stress in polar bears with alopecia. Our results support an alternative mechanism of investigation into the causative agents that, when used proactively, could serve as an early indicator for populations and species at risk. We suggest that current or classical methods for investigation into events of unusual morbidity and mortality can be costly, sometimes unfocused, and often inconclusive. Advances in technology allow for implementation of a holistic system of surveillance and investigation that could provide early warning of health concerns in wildlife species important to humans.

2014-12-15

Severe lymphocytosis and leukocytosis were detected during examination of a 10-year-old sexually intact male bat-eared fox (Otocyon megalotis) with regionally extensive alopecia. A CBC revealed severe leukocytosis (39,100 leukocytes/μL) and marked lymphocytosis (90%). A blood smear consisted predominantly of intermediate-sized lymphocytes and few large lymphocytes, with mild to moderate nuclear atypia. These findings were highly suggestive of chronic lymphocytic leukemia (CLL). Cytologic evaluation of bone marrow aspirates revealed no evidence of overt malignancy, with 10% of all cells identified as small to intermediate-sized mature lymphocytes. Treatment with chlorambucil and prednisone administered orally over a 1.8-year period decreased the leukocyte and lymphocyte counts to within reference intervals with no adverse effects. Although repeated flow cytometry revealed evidence of residual disease, the fox remained free of clinical disease, and WBC counts were within reference intervals for this species. At 22 months after initial evaluation, the fox was euthanized because of debilitating arthritis. No evidence of CLL was detected grossly or histologically during necropsy. To the authors' knowledge, this was the first report of CLL in a bat-eared fox and first successful treatment in a nondomestic carnivore. Treatment in accordance with a chemotherapeutic protocol successfully resolved the leukocytosis and lymphocytosis with no serious adverse effects. Description of this fox and the treatment protocol should provide a valuable reference for future cases in this and other nondomestic canine species.

Office-Based Diagnosis of Demodex Using Smartphone.

Demodex is an important pathogen in ophthalmology. It is believed to cause a variety of eyelid and eyelash diseases. Currently, light microscopes are being used for imaging demodex. However, microscopes are not available everywhere. Also, it is not cost-effective to perform light microscopy in every case. In this case, we demonstrate a new method: imaging demodex using cell phone. A 90-diopter noncontact double aspheric lens was attached to the posterior camera of the smartphone with clear tape. An eyelash of a patient with blepharitis was removed. A video was taken using smartphone. There was a moving demodex parasite in the root of the eyelash. A clear video image could be taken using the smartphone. A smartphone and a 90-diopter lens are adequate for the imaging and diagnosis of demodex.

The aim of this study was to acquire a deeper understanding of male experiences on the emotional and social impact of their partners' mastectomy and chemotherapy-induced alopecia. A purposive sample of 16 males whose partners had undergone mastectomy and alopecia due to chemotherapy was chosen. The data were collected through a semi-structured interview method. Interpretative Phenomenological Analysis of tape-recorded interviews was employed. Two main themes emerged from the data: facing the changes and my wife and I at present. Male partners were affected differently by the change in the physical appearance of their female partners. Our study participants said it was a difficult experience to see their partners for the first time after the surgery, but they emphasized that it was more important that their partners were healthy than the fact that they did not have a breast and hair. They also said they did not know how to behave towards their partners after surgery and/or chemotherapy. Nevertheless, they felt that the disease process of their partners had strengthened their bond and had not negatively influenced their relationship with others. The changes in the partners' physical appearance after mastectomy and chemotherapy affected males differently in psychological, emotional and social terms. Since nurses working in this field are in contact with patients during all phases of treatment and care, it would be positive and beneficial to plan nursing interventions that give emotional support for male partners of patients with breast cancer.

Efficacy of a cosmetic phyto-caffeine shampoo in female androgenetic alopecia.

Bussoletti, Carolina; Tolaini, Maria V; Celleno, Leonardo

2018-03-06

Androgenetic alopecia (AGA) is the most common type of hair loss in both males as well as females, occurring in up to 57% of women by the age of 80 years. Androgenetic alopecia is associated with a high psychological burden and often results in substantially reduced quality of life, poor body image and low self-esteem, particularly in women. Caffeine-based products have shown promise, both in vitro and in vivo, as potential treatments for AGA. This study was performed to determine the efficacy of a phyto-caffeine- containing shampoo used over a 6-month period in female subjects with AGA. This was a single-centre, double-blind parallel trial in which female subjects with AGA were randomized to either a phyto-caffeine-containing shampoo or a control shampoo. The primary endpoint was the change from baseline in the number of hairs pulled in a hair pull test at 6 months. Hair loss intensity, hair strength, subject satisfaction and tolerability were also assessed. Subjects using the phyto-caffeine-containing shampoo had significantly fewer hairs pulled in a hair pull test at 6 months, compared with subjects using the control shampoo (-3.1 vs -0.5 hairs; p<0.001). The majority of pre-specified secondary endpoints were also significantly improved for subjects using the phyto-caffeine- containing shampoo, compared with controls. Both products were very well tolerated. Compared with a control shampoo, a phyto-caffeine-containing shampoo was more efficacious, with respect to the number of hairs being pulled out at 6 months, hair loss intensity and hair strength in subjects with AGA.

Androgenetic alopecia (AGA) is a hair loss disorder that commonly affects middle-aged men. To date, the properties of a number of natural or synthetic substances have been investigated for their ability to improve the condition. To evaluate the hair growth-promoting activities of an extract from the root of Sophora flavescens Aiton. We used a human hair keratinocyte proliferation assay and ex vivo organ cultures of human hair follicle to examine the potential of the extract to stimulate hair growth via anagen elongation. We isolated the compounds promoting the growth of epithelial cells, and determined their chemical structures. A randomized, double-blinded, placebo-controlled clinical study for S. flavescens extract was carried out for 6 months with patients with AGA. The extract stimulated the proliferation of hair keratinocytes at a concentration of 0.1 ng/mL, while 100 ng/mL of the extract had a marked effect on hair shaft elongation in an organ culture of human hair follicle. Cell proliferation assay-directed fractionation led to the identification of two pterocarpan derivatives, L-maackiain and medicarpin, as active compounds that promote the proliferation of human hair keratinocytes. Studies in human subjects showed that improvement in the inspected alopecia scores in the lotion plus extract group were significant over a period of 6 months (P < 0.01). S. flavescens root extract is effective for the treatment of AGA. The isolated two pterocarpans might have important role in this effect. © 2015 British Association of Dermatologists.

Toward the Clonotype Analysis of Alopecia Areata-Specific, Intralesional Human CD8+ T Lymphocytes.

PubMed

Bertolini, Marta; Uchida, Youhei; Paus, Ralf

2015-11-01

Alopecia areata (AA) is an organ-restricted autoimmune disease that mainly affects the hair follicle (HF). Several findings support a key primary effector role of CD8+ T cells in the disease pathogenesis. Autoreactive CD8+ T cells are not only present in the characteristic peribulbar inflammatory cell infiltrate of lesional AA HFs but are also found to be infiltrating in lesional HF epithelium where they are thought to recognize major histocompatibility complex class I-presented (auto-)antigens. However, the latter still remain unidentified. Therefore, one key aim in AA research is to identify the clonotypes of autoaggressive, intralesional CD8+ T cells. Therapeutically, this is important (a) so that these lymphocytes can be selectively eliminated or inhibited, (b) to identify the-as yet elusive-key (auto-)antigens in AA, and/or (c) to induce peripheral tolerance against the latter. Therefore, we have recently embarked on a National Alopecia Areata Foundation-supported project that attempts to isolate disease-specific, intralesional CD8+ T cells from AA skin in order to determine their TCR clonotype, using two complementary strategies. The first method is based on the enzymatic skin digestion from lesional AA skin, followed by either MACS technology and single-cell picking or FACS cell sorting, while the second method on laser microdissection. The identification of disease-specific TCRs can serve as a basis for specific AA immunotherapy along the lines sketched above and may possibly also provide prognostic biomarkers. If successful, this research strategy promises to permit, at long last, the causal therapy of AA.

Mutant laboratory mice with abnormalities in hair follicle morphogenesis, cycling, and/or structure: an update.

Nakamura, Motonobu; Schneider, Marlon R; Schmidt-Ullrich, Ruth; Paus, Ralf

2013-01-01

Human hair disorders comprise a number of different types of alopecia, atrichia, hypotrichosis, distinct hair shaft disorders as well as hirsutism and hypertrichosis. Their causes vary from genodermatoses (e.g. hypotrichoses) via immunological disorders (e.g. alopecia areata, autoimmune cicatrical alopecias) to hormone-dependent abnormalities (e.g. androgenetic alopecia). A large number of spontaneous mouse mutants and genetically engineered mice develop abnormalities in hair follicle morphogenesis, cycling, and/or hair shaft formation, whose analysis has proven invaluable to define the molecular regulation of hair growth, ranging from hair follicle development, and cycling to hair shaft formation and stem cell biology. Also, the accumulating reports on hair phenotypes of mouse strains provide important pointers to better understand the molecular mechanisms underlying human hair growth disorders. Since numerous new mouse mutants with a hair phenotype have been reported since the publication of our earlier review on this matter a decade ago, we present here an updated, tabulated mini-review. The updated annotated tables list a wide selection of mouse mutants with hair growth abnormalities, classified into four categories: Mutations that affect hair follicle (1) morphogenesis, (2) cycling, (3) structure, and (4) mutations that induce extrafollicular events (for example immune system defects) resulting in secondary hair growth abnormalities. This synthesis is intended to provide a useful source of reference when studying the molecular controls of hair follicle growth and differentiation, and whenever the hair phenotypes of a newly generated mouse mutant need to be compared with existing ones.

Folliculitis decalvans (FD) is a form of primary neutrophilic scarring alopecia that is characterized clinically by chronic suppurative folliculitis and often associated with pruritus or even pain. Treatment of FD is often difficult. Herein, we report a case of recalcitrant and painful folliculitis decalvans refractory to antibiotic and anti-inflammatory therapies, which was successfully treated by intensity-modulated radiotherapy (IMRT) in order to irreversibly eliminate hair follicles that prove to be one etiological trigger. A 45-year-old male patient with a refractory FD presented with a crusting suppurative folliculitis and atrophic scarring patches on the scalp associated with pain and pruritus. We attempted relief of symptoms by reducing scalp inflammation and eliminating hair follicles through radiation. We delivered 11.0 Gy in two radiation series using tomotherapy, 5.0 Gy in 5 equivalent fractions as a first radiation course. The symptoms markedly decreased but did not totally disappear. Therefore, we delivered a second radiation series 4 months later with an additional 6 Gy. This led to almost complete epilation on the scalp and abolished pain and pruritus on the capillitium. The patient was regularly followed up until 26 months after radiotherapy. Draining lesions or exudation did not recur. He only experienced discrete hair regrowth in the occipital region with folliculitis 12 months after radiotherapy. These residual lesions are currently treated with laser epilation therapy. A radical approach to eliminating hair follicles by repeated radiation therapy may induce lasting relief of symptoms in chronic suppurative FD associated with persistent trichodynia.

Body to Scalp: Evolving Trends in Body Hair Transplantation

Saxena, Kuldeep; Savant, Sandeep S.

2017-01-01

Follicular unit extraction (FUE) is becoming an increasingly popular method for hair restoration. As FUE leaves behind no linear scars, it is more suitable to harvest from various body areas including beard, chest, and extremities in hirsute individuals. Body hair characteristics such as thickness, length, and hair cycle may not completely match to that of the scalp hair. The techniques of harvesting body hairs are more time consuming, requiring higher degree of skill than regular scalp FUE. Body hair transplantation can be successfully used either alone or in combination with scalp hair in advanced grades of baldness, for improving the cosmetic appearance of hairlines and in scarring alopecia when there is paucity of donor scalp hair. Harvesting of body hairs opens up a new viable donor source for hair restoration surgeons, especially in cases of advanced Norwood grades five and above of androgenetic alopecia. PMID:28584752

Various systemic corticosteroid therapies are used for alopecia areata (AA). Pulse therapy using methylprednisolone is a treatment approach for AA. The efficacy of multiple courses of pulse therapy for various severities of AA was evaluated. AA patients with less than 50% hair loss, less than or equal to 6 months after AA onset, needed 1.9 courses of pulse therapy for vellus hair to develop. On the other hand, AA patients with more than 50% hair loss, less than 6 months after AA onset, needed more courses of pulse therapy for vellus hair to develop. Regardless of the disease duration, AA patients with less than 50% hair loss showed a good response rate (100%) after both a short period and a long period after therapy. After receiving multiple courses of pulse therapy, the AA patients with more than 50% hair loss also showed improvement with limited adverse reactions. © 2016 Japanese Dermatological Association.

Various therapeutic agents have been described for the treatment of alopecia areata (AA), but none are curative or preventive. The aim of AA treatment is to suppress the activity of the disease. The high rate of spontaneous remission and the paucity of randomized, double-blind, placebo-controlled studies make the evidence-based assessment of these therapies difficult. The second part of this two-part series on AA discusses treatment options in detail and suggests treatment plans according to specific disease presentation. It also reviews recently reported experimental treatment options and potential directions for future disease management. After completing this learning activity, participants should be able to compare the efficacy and safety of various treatment options, formulate a treatment plan tailored to individual patients, and recognize recently described treatments and potential therapeutic approaches.

Platelet rich plasma for the management of hair loss: Better alone or in combination?

2018-06-14

Platelet-rich plasma (PRP) and autologous protein-based treatments have recently emerged as a potential therapeutic approach for hair loss-related disorders including androgenetic alopecia and alopecia areata. The safety and efficacy of repeated intradermal injections of PRP has proved to promote hair growth in a number of randomized clinical trials. Biologically active proteins and cytokines released upon platelet activation have shown to induce folliculogenesis and activate the anagen growing phase of dormant bulbs. Interestingly, further studies have revealed that combining PRP with other hair loss-related products may enhance the final performance of the treatment. These synergistic approaches include Food and Drug Administration (FDA) approved drugs such as finasteride or minoxidil, bioactive macromolecules and cell-based therapies. Here, recent research involving alone or combined therapy with platelet-rich plasma for the management of hair loss-related disorders are outlined and future prospects are discussed. © 2018 Wiley Periodicals, Inc.

Keratin 17 null mice exhibit age- and strain-dependent alopecia

2002-01-01

Onset of type I keratin 17 (K17) synthesis marks the adoption of an appendageal fate within embryonic ectoderm, and its expression persists in specific cell types within mature hair, glands, and nail. We report that K17 null mice develop severe alopecia during the first week postbirth, correlating with hair fragility, alterations in follicular histology, and apoptosis in matrix cells. These alterations are incompletely penetrant and normalize starting with the first postnatal cycle. Absence of a hair phenotype correlates with a genetic strain-dependent compensation by related keratins, including K16. These findings reveal a crucial role for K17 in the structural integrity of the first hair produced and the survival of hair-producing cells. Given that identical inherited mutations in this gene can cause either pachyonychia congenita or steatocystoma multiplex, the features of this mouse model suggest that this clinical heterogeneity arises from a cell type-specific, genetically determined compensation by related keratins.

Johnson-McMillin syndrome, a neuroectodermal syndrome with conductive hearing loss and microtia: report of a new case.

In 1983, Johnson et al. described 16 related individuals with alopecia, anosmia or hyposmia, conductive hearing loss, microtia and/or atresia of the external auditory canal, and hypogonadotrophic hypogonadism inherited in an autosomal dominant pattern. Other less constant manifestations included facial asymmetry, mental retardation, congenital heart defect, cleft palate, and choanal stenosis. An isolated case was reported later (Johnston et al. [1987: Am J Med Genet 26: 925-927]) and thereafter an affected mother and son (Hennekam and Holtus [1993: Am J Med Genet 47: 714-716]). We describe an additional unrelated female patient with features resembling those of the previously reported cases. She presented with intrauterine growth deficiency, microcephaly, alopecia, bilateral microtia with canal atresia, conductive hearing loss, partial left facial palsy, posterior cleft palate, left choanal stenosis, tetralogy of Fallot, developmental delay, and right thumb polydactyly. Because the phenotypic abnormalities in this syndrome affect the brain, facial structures, ectoderm and its derivatives, outflow tract of the heart, and Rathke's pouch derivatives, this has suggested to previous authors etiologic involvement of the ectoderm and neuroectoderm of the first and second branchial arches, Rathke's pouch, and the diencephalon. Microtia with conductive hearing loss differentiates the condition from other ectodermal dysplasias. In the initial report, females appeared somewhat less affected than males, and there was male-to-male transmission. The mother of our patient manifests subtle features, which suggest she may be a mildly affected female. Additionally, there is a family history of early-onset alopecia in the maternal grandfather's relatives. Copyright 2003 Wiley-Liss, Inc.

Results of 20- versus 45-min post-infusion scalp cooling time in the prevention of docetaxel-induced alopecia.

For patients, chemotherapy-induced alopecia (CIA) is one of the most distressing side effects of treatment. Scalp cooling can prevent or minimise CIA; the results may depend on the duration of cooling. Since a previous study on post-infusion cooling time in patients treated with docetaxel chemotherapy found no difference between 90 and 45 min, we investigated whether hair-preserving results could be maintained with a shorter post-infusion cooling time. In this prospective, multi-centre randomised study, 134 patients who started treatment with docetaxel 75-100 mg/m(2) in a 3-weekly schedule were randomly assigned in a 1:1 ratio to a post-infusion cooling time of 45 or 20 min. The primary end point was the need for a wig or other head covering as assessed by the patient. A visual analogue scale (VAS) with a range from 0 (not tolerable) to 10 (very tolerable) was used to measure tolerance. Scalp cooling results were similar for 45- and 20-min post-infusion cooling times. Thirty-three out of 45 patients (73 %) treated with 20 min of post-infusion cooling did not need a form of head covering, compared with 41 out of 52 patients (79 %) treated with 45 min of post-infusion cooling (p = 0.5). The procedure was well tolerated (mean visual analogue score 8.3). Six patients stopped due to intolerance during the first treatment cycle. A 20-min post-infusion cooling time is effective and tolerable for patients treated with scalp cooling to prevent docetaxel-induced alopecia. Trialregister.nl Identifier, NTR 1856.

Radiation-induced ocular injury secondary to treatment of nasal cancer occurs in humans and animals. Dogs with nasal carcinomas were randomized to receive 36 to 67.5 Gy in fractionated doses given in 4 weeks using a 6 MV linear accelerator. Ophthalmic examinations were performed according to a predetermined protocol and eyes were removed for histologic examination when dogs were euthanatized. The eye in the radiation field exhibited greater injury than the contralateral eye with nasal areas of the globe having more severe lesions than temporal areas. Lesions occurred in all dogs and at all doses. At 1 month or less postirradiation treatment, all dogs had blepharitis, keratoconjunctivitis and corneal epithelial atrophy. Surface lesions persisted in all eyes, becoming less severe and more chronic with time. At 3-6 months postirradiation treatment, degenerative angiopathy of retinal vessels appeared with multifocal retinal hemorrhage and mild diffuse retinal degeneration which affected outer layers first and progressed inwardly with time. At 6 months postirradiation treatment, there were cataracts, fibrosis of retinal vessel walls with loss of vascular smooth muscle, retinal hemorrhage, and mild to moderate retinal degeneration. At 1 year postirradiation treatment, retinal vessels remained sclerotic, retinal hemorrhage was less frequent, and there was moderate retinal degeneration with swelling and loss of ganglion cells. By 2 years or more postirradiation treatment, optic nerve axonal degeneration secondary to retinal changes had appeared. Tapetal and choroidal atrophy were inconsistently seen. Thus, ocular lesions at the doses received developed along a relatively predictable time course and recovery was not seen. Structures of the canine eye appear sufficiently sensitive that even relatively low total doses given in small doses per fraction cause significant long-term injury.

The relationship between thyroxine, oestradiol, and postnatal alopecia, with relevance to women's health in general.

PubMed

Pringle, T

2000-11-01

Post-partum hair loss is possibly due to a reduction in the levels of oestradiol and thyroxine postnatally. Alopecia and/or a persistent loss of hair condition postnatally is associated with a group of symptoms (a syndrome), wherein postnatal depression is significant, as a result of physiologically inadequate levels of thyroxine (T4) and oestradiol (E2), secondary to physiological postnatal anterior pituitary dysfunction. Using this hypothesis, the author began to apply the same hypothesis to other female patients, who were not postpartum, but with similar symptomatology. The author became aware of the necessity for an adequate level of T4 to be present for correct oestrogenization to occur. He then goes on to hypothesize on the synergistic relationship that T4 and oestradiol may have in premenstrual syndrome (PMS), infertility, dysfunctional uterine bleeding, poor placental function, osteoporosis, and anorexia nervosa. He also discusses the role lowering T4 could play in the treatment of terminal cancer breast in premenopausal women.

Low-level laser/light therapy for androgenetic alopecia.

Androgenetic alopecia (AGA) is a persistent and pervasive condition that affects men worldwide. Some common treatment options for AGA include hair prosthetics, oral and topical medications, and surgical hair restoration (SHR). Pharmaceutical and SHR treatments are associated with limitations including adverse side effects and significant financial burden. Low-level laser or light (LLL) devices offer alternative treatment options that are not typically associated with adverse side effects or significant costs. There are clinic- and home-based LLL devices. One home-based laser comb device has set a standard for others; however, this device requires time devoted to carefully moving the comb through the hair to allow laser penetration to the scalp. A novel helmet-like LLL device for hair growth has proven effective in preliminary trials and allows for hands-free use. Regardless, there are few clinical trials that have been conducted regarding LLL devices for AGA and results are mixed. Further research is required to establish the true efficacy of these devices for hair growth in comparison to existing alternative therapies.

Adenosine is an effective treatment for androgenetic alopecia (AGA) in Japanese men and women. Adenosine exerts its effects by significantly increasing the proportion of thick hair. In this study, we assessed the clinical outcome of adenosine treatment for 6 months in 38 Caucasian men. The change in proportion of thick hair (≥60 μm) compared with baseline in the adenosine group was significantly higher than that in the placebo group (P < 0.0001). The change in vellus hair proportion (<40 μm) was significantly lower in the adenosine group than that in the placebo group (P = 0.0154). The change in hair density compared with baseline of the adenosine group was also significantly higher compared with that of the placebo group (P = 0.0470). No adverse effects due to treatment were noted during this study by dermatological evaluation. Adenosine is effective in increasing the proportion of thick hair in Caucasian men with AGA as well as in Japanese men and women. © 2015 Japanese Dermatological Association.

Trichotillomania: Bizzare Patern of Hair Loss at 11-Year-old Girl.

Zímová, Jana; Zímová, Pavlína

2016-06-01

Trichotillomania (TTM) is defined by the Diagnostics and Statistic Manual of Mental Disorders, 4th edition (DMS-IV) as hair loss from a patient`s repetitive self-pulling of hair. The disorder is included under anxiety disorders because it shares some obsessive-compulsive features. Patients have the tendency towards feelings of unattractiveness, body dissatisfaction, and low self-esteem (1,2). It is a major psychiatric problem, but many patients with this disorder first present to a dermatologist. An 11-year-old girl came to our department with a 2-month history of diffuse hair loss on the frontoparietal and parietotemporal area (Figure 1). She had originally been examined by a pediatrician with the diagnosis of alopecia areata. The patient`s personal history included hay fever and shortsightedness, and she suffered from varicella and mononucleosis. Nobody in the family history suffered from alopecia areata, but her father has male androgenetic alopecia (Norwood/Hamilton MAGA C3F3). The mother noticed that the child had had changeable mood for about 2 months and did not want to communicate with other persons in the family. The family did not have any pet at home. At school, her favorite subjects were Math and Computer Studies. She did not like Physical Education and did not participate in any sport activities during her free time. This was very strange because she was obese (body-mass index (BMI) 24.69). She was sometimes angry with her 13-year-old sister who had better results at school. The girl had suddenly started to wear a blue scarf. The parents did not notice that she pulled out her hair at home. Dermatological examination of the capillitium found a zone of incomplete alopecia in the frontoparietal and parietotemporal area, without inflammation, desquamation, and scaring. Hairs were of variable length (Figure 1). There was a patch of incomplete alopecia above the forehead between two stripes of hair of variable length (Figure 2). The hair pull test was negative along the edges of the alopecia. Mycological examination from the skin capillitium was negative. The trichoscopy and skin biopsy of the parietotemporal region of the capillitium (Figure 3) confirmed trichotillomania. Laboratory tests (blood count, iron, ferritin, transferrin, selenium, zinc, vitamin B12, folic acid, serology and hormones of thyroid gland) were negative. We referred the girl for ophthalmologic and psychological examination. Ophthalmologic examination proved that there was no need to add any more diopters. The psychological examination provided us with a picture in which she drew her family (Figure 4). The strongest authority in the family was the mother because she looked after the girls for most of the day. She was in the first place in the picture. The father had longer working hours and spent more time outside the home. He worked as a long vehicle driver. He was in the second place in the picture. There was sibling rivalry between the girls, but the parents did not notice this problem and preferred the older daughter. She was successful at school and was prettier (slim, higher, curly brown hair, without spectacles). Our 11-years-old patient noticed all these differences between them, but at her level of mental development was not able to cope with this problem. She wanted to be her sister's equal. The sister is drawn in the picture in the third place next to father, while the patient's own figure was drawn larger and slim even though she was obese. Notably, all three female figures had very nice long brown hair. It seemed that the mother and our patient had better quality of hair and more intense color than the sister in the drawing. The only hairless person in the picture was the father. The girl did not want to talk about her problems and feelings at home. Then it was confirmed that our patient was very sensitive, anxious, willful, and withdrawn. She was interested in her body and very perceptive of her physical appearance. From the psychological point of view, the parents started to pay more interest to their younger daughter and tried to understand and help her. After consultation with the psychiatrist, we did not start psychopharmacologic therapy for trichotillomania; instead, we started treatment with cognitive behavioral therapy, mild shampoo, mild topical steroids (e.g. hydrocortisone butyrate 0.1%) in solution and methionine in capsules. With parents' cooperation, the treatment was successful. The name trichotillomania was first employed by the French dermatologist Francois Henri Hallopeau in 1889, who described a young man pulling his hair out in tufts (3-5). The word is derived from the Greek thrix (hair), tillein (to pull), and mania (madness) (5). The prevalence of TTM in the general adult population ranges from 0.6% to 4%, and 2-4% of the general psychiatric outpatient population meet the criteria for TTM (2-5). The prevalence among children and adolescents has been estimated at less than 1% (5). The disease can occur at any age and in any sex. The age of onset of hair pulling is significantly later for men than for women (3). There are three subsets of age: preschool children, preadolescents to young adults, and adults. The mean age of onset is pre-pubertal. It ranges from 8 to 13 years (on average 11.3 years) (2-5). The occurrence of hair-pulling in the first year of life is a rare event, probably comprising <1% of cases (5). The etiology of TTM is complex and may be triggered by a psychosocial stressor within the family, such as separation from an attachment figure, hospitalization of the child or parent, birth of a younger sibling, sibling rivalry, moving to a new house, or problems with school performance. It has been hypothesized that the habit may begin with "playing" with the hair, with later chronic pulling resulting in obvious hair loss (2). Environment is a factor because children usually pull their hair when alone and in relaxed surroundings. The bedroom, bathroom, or family room are "high-risk" situations for hair-pulling (5). Men and women also differed in terms of the hair pulling site (men pull hair from the stomach/back and the moustache/beard areas, while women pull from the scalp) (3). Pulling hair from siblings, pets, dolls, and stuffed animals has also been documented, often occurring in the same pattern as in the patient (5). Genetic factors contributing to the development of TTM are mutations of the SLITRK1 gene, which plays a role in cortex development and neuronal growth. The protein SAPAP3 has been present in 4.2% of TTM cases and patients with obsessive-compulsive disorder (OCD). It may be involved in the development of the spectrum of OCD. A significantly different concordance rate for TTM was found in monozygotic (38.1%) compared with dizygotic (0%) twins in 34 pairs (3). The core diagnostic feature is the repetitive pulling of hairs from one`s own body, resulting in hair loss. The targeted hair is mostly on the scalp (75%), but may also be from the eyebrows (42%), eyelashes (53%), beard (10%), and pubic area (17%) (3,5). There are three subtypes of hair pulling - early onset, automatic, and focused. Diagnostic criteria for TTM according to DSM-IV criteria are (2,3,5): 1) recurrent pulling of one`s hair resulting in noticeable hair loss; 2) an increasing sense of tension immediately prior to pulling out the hair or when attempting to resist the behavior; 3) pleasure, gratification, or relief when pulling out the hair; 4) the disturbance is not better accounted for by another mental disorder and is not due to a general medical condition (e.g., a dermatologic condition); 5) the disturbance causes clinically significant distress or impairment in social, occupational, or other important areas of functioning. The differential diagnosis includes alopecia areata (Table 1) (6), tinea capitis, telogen effluvium, secondary syphilis, traction alopecia, loose anagen syndrome, lichen planopilaris, alopecia mucinosa, and scleroderma (2-5). Biopsy of an involved area (ideally from a recent site of hair loss) can help to confirm the diagnosis (5). On histologic examination, there are typically increased numbers of catagen and telogen hairs without evidence of inflammation. Chronic hair pulling induces a catagen phase, and more hairs will be telogen hairs. Pigment casts and empty anagen follicles are often seen. Perifollicular hemorrhage near the hair bulb is an indicator of TTM (2). Complications of TTM are rare, but they comprise secondary bacterial infections with regional lymphadenopathy as a result of picking and scratching at the scalp. Many patients play with and ingest the pulled hairs (e.g. touching the hair to lips, biting, and chewing). Trichophagia (ingestion of the hair) can lead to a rare complication named trichobezoar (a "hair ball" in stomach). This habit is present in approximately 5% to 30% of adult patients, but it is less frequent in children. Patient with trichophagia present with pallor, nausea, vomiting, anorexia, and weight loss. Radiologic examination and gastroscopy should not be delayed (2,4,5). The management of the disease is difficult and requires strong cooperation between the physician, patient, and parents. The dermatologist cannot take part in the therapy, strictly speaking, but without the psychological, psychopharmacologic, and topic dermatologic treatment a vicious circle will be perpetuated.

Comparison of azelaic acid and anthralin for the therapy of patchy alopecia areata: a pilot study.

Although topical azelaic acid has been previously used for the treatment of alopecia, no controlled trials of azelaic acid for this condition have been conducted to date. The goal of this study was to determine the efficacy, tolerability, and safety of azelaic acid treatment in patients with patchy alopecia areata (AA) in comparison with anthralin (dithranol) treatment. This study included 31 subjects with patchy AA who did not receive any treatment for at least 1 month prior to the study. Demographic and clinical characteristics of these subjects were recorded at baseline. Subjects were randomized to apply either 20% azelaic acid (15 subjects) or 0.5% anthralin (16 subjects) for 12 consecutive weeks. In a subsequent 8-week follow-up period no cream was applied. Two independent investigators performed an efficacy evaluation with clinical examination using a terminal hair regrowth score (RGS) with a scale ranging from 0 (inadequate response) to 2 (complete response) at week 20. Partial response was accepted as score 1. Both groups were well matched for the relevant demographic and clinical indicators affecting treatment response at baseline. All subjects completed the trial. At week 20 the RGS was 1.27 +/- 0.9 in the azelaic acid group versus 1.37 +/- 0.8 in the anthralin group (p > 0.05). A complete response was observed in 53.3% of cases in the azelaic acid group (8 of 15) compared with 56.2% (9 of 16) in the anthralin group (p > 0.05). No serious adverse events were observed in either group during the study. The present pilot study showed that the use of azelaic acid gave similar results to anthralin with regard to hair regrowth, and that it can be an effective topical therapy for patchy AA. More extensive trials are necessary, however, to reach a definitive conclusion.

Alopecia areata usually presents as patchy, nonscarring hair loss. It seems to be an immune mediated disease, whereas genetic predisposition, environmental and psychological triggers may be involved in its aetiology. To study the epidemiology, clinical aspects, associations, and treatment of alopecia areata in the paediatric population of Peadiatric Dermatology outpatients over a 9-year period. Some psychologic characteristics were also assessed. Descriptive and retrospective study of all newly diagnosed AA cases seen from January 2000 to December 2008 at the Hospital de São Marcos' Paediatric Dermatology Department. Fifteen patients with AA were interviewed for psycologic evaluation. Forty-eight cases (54% male/46% female) were identified. Mean age at presentation was 7.8 years. Family history of AA was reported in 10% of the cases, and in 25% there was a personal and/or family history of atopy. The majority of patients (82%) had mild disease and topical corticotherapy was the first-line treatment for limited AA. Fifty-four percent of these patients had a complete resolution of the lesions with treatment. Systemic treatment (corticosteroids and/or ciclosporin) was used in 71% of patients with extensive disease (more than 50% hair loss). Only one of these patients had a sustained clinical improvement after treatment. Twelve out of 15 respondents (80%) recalled stressful events preceding hair loss. Our findings are similar to those reported in other studies. Epidemiologic studies of AA are available in adulthood but there is a paucity of literature on children with AA. A holistic approach is important in the management of childhood AA as the disease can have a severe psychologic impact on an individual's well-being.

To investigate the prevalence and associations with clinical manifestations of anti- P ribosomal antibodies in patients with juvenile-onset and adult-onset systemic lupus erythematosus (SLE). Clinical and serological data of 30 patients with juvenile-onset SLE (age at onset younger than 16 years old) were compared with data of 92 patients with adult-onset SLE. Symptoms occurring during the entire disease course were considered. Anti- P ribosomal antibodies were tested by ELISA. Anti- P ribosomal antibodies were found significantly more often in pediatric-onset SLE patients (26.7% vs. 6.5%; OR=5.21 [CI95%=1.6-16.5], p=0.003). Alopecia (OR=10.11, CI 95%=1.25-97) and skin rash (non discoid) (OR=4.1, CI 95%=1.25-13.89) were significantly associated with anti- P ribosomal antibodies. Anti-ribosomal P antibodies are more often found in patients with juvenile SLE. Alopecia and skin rash were the only clinical manifestations associated to anti-ribosomal P antibodies.

We aimed to determine the risk of alopecia areata (AA) and vitiligo associated with atopic dermatitis (AD) in a large cohort of US women, the Nurses' Health Study 2. We used logistic regression to calculate age- and multivariate-adjusted odds ratios to determine the risk of incident AA and vitiligo associated with AD diagnosed in or before 2009. A total of 87 406 and 87 447 participants were included in the AA and vitiligo analyses, respectively. A history of AD in 2009 was reported in 11% of participants. There were 147 incident cases of AA and 98 incident cases of vitiligo over 2 years of follow-up. AD was associated with increased risk of developing AA (OR 1.80, 95% CI 1.18-2.76) and vitiligo (OR 2.14, 95% CI 1.29-3.54) in multivariate models. In this study of US women, AD was associated with increased risk of incident vitiligo and AA in adulthood. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Novel enzymatic assay predicts minoxidil response in the treatment of androgenetic alopecia.

PubMed

2014-01-01

Topical minoxidil is the most common drug used for the treatment of androgenetic alopecia (AGA) in men and women. Although topical minoxidil exhibits a good safety profile, the efficacy in the overall population remains relatively low at 30-40%. To observe significant improvement in hair growth, minoxidil is typically used daily for a period of at least 3-4 months. Due to the significant time commitment and low response rate, a biomarker for predicting patient response prior to therapy would be advantageous. Minoxidil is converted in the scalp to its active form, minoxidil sulfate, by the sulfotransferase enzyme SULT1A1. We hypothesized that SULT1A1 enzyme activity in the hair follicle correlates with minoxidil response for the treatment of AGA. Our preliminary retrospective study of a SULT1A1 activity assay demonstrates 95% sensitivity and 73% specificity in predicting minoxidil treatment response for AGA. A larger prospective study is now under way to further validate this novel assay. © 2013 Wiley Periodicals, Inc.

Platelet-rich plasma—an ‘Elixir’ for treatment of alopecia: personal experience on 117 patients with review of literature

2017-01-01

Platelet-rich plasma (PRP) has emerged as a new treatment modality in regenerative plastic surgery and dermatology. PRP is a simple, cost-effective and feasible treatment option with high patient satisfaction for hair loss and can be regarded as a valuable adjuvant treatment modality for androgenic alopecia and other types of non-scarring alopecias. Authors have proposed a hair model termed “Golden anchorage with ‘molecular locking’ of ectodermal and mesenchymal components for survival and integrity of hair follicle (HF)” in this article. Golden anchorage comprises of bulge stem cells, ectodermal basement membrane and bulge portion of APM. PRP with its autologous supply of millions of growth factors works on ‘Golden anchorage’ along with keratinocytes (PDGF), dermal papilla (IGF and fibroblast growth factor), vasculature (VEGF and PDGF) and neural cells (Nerve Growth Factor) in a multipronged manner serving as an ‘elixir’ for hair growth and improving overall environment.

The etiology of androgenic alopecia (AGA) involves several factors, including genetics, androgens, age and nutrition. Digit-length ratio of the index and ring finger (2D:4D) is an indicator of prenatal exposure to sex hormones. There is a paucity of studies that systemically review the possible positive predictive value of 2D:4D in the development of AGA. We performed a single-site, descriptive-analytical study among a racially homogeneous population. Our results revealed that no significant association was determined between right 2D:4D and AGA severity within our entire population (P=0.384, r=0.025), however a positive correlation coefficient was identified in subjects above the age of 40. Based on the receiver operating characteristic curve analysis, 2D:4D does not predict the development of AGA. AGA is truly a multifactorial disease. Further, our findings suggest that increased in utero exposure to androgens as a fetus does not predispose men to develop AGA.

Alopecia areata associated with abacavir therapy.

Abacavir is a nucleoside reverse-transcriptase inhibitor that has been approved for use in combination with other retroviral agents in the treatment of HIV infection. Common adverse reactions include headache, fatigue, nausea, and rash. A fatal hypersensitivity reaction may occur in 5% of patients receiving abacavir; therefore, screening for HLA-B5701 should be performed before starting abacavir. Alopecia areata (AA) is infrequently reported in HIV-infected patients. Certain underlying conditions have been associated with AA, including a decreased CD4:CD8 ratio related to the progression of HIV infection, some opportunistic infections, and syphilis. Several antiretroviral drugs, such as zidovudine, indinavir, indinavir/ritonavir, lopinavir/ritonavir, and atazanavir/ritonavir have been implicated in the development of AA. At present, the occurrence of AA has not been associated with abacavir use. We cannot exclude that the use of abacavir and the development of AA could be coincidental. Nevertheless, patients given abacavir should be monitored for hair loss and the drug discontinued promptly if such signs appear.

A Case Report of Cushing's Disease Presenting as Hair Loss

Lefkowitz, Emily G.; Cossman, Jack P.; Fournier, John B.

2017-01-01

Cushing's syndrome is a rare endocrine disorder that comprises a large group of signs and symptoms resulting from chronic exposure to excess corticosteroids. Most cases of Cushing's syndrome are due to increased adrenocorticotropic hormone production from a pituitary adenoma, which is referred to as Cushing's disease. Most of the signs and symptoms are nonspecific and common in the general population, making a diagnosis often challenging. However, several dermatological manifestations, such as fragile skin, easy bruising, and reddish purple striae, are more discriminatory. Because uncontrolled Cushing's syndrome of any etiology is associated with substantial morbidity, including increased cardiovascular disease and mortality, it is important to make an early diagnosis. Unfortunately, median delays of 2 years to diagnosis have been reported. We report a case of a woman who had multiple dermatological findings, including facial plethora, easy bruising, violaceous striae, hirsutism, and acne, the latter 2 signs reflecting androgen excess. Of interest, our patient presented with a chief complaint of hair loss, a common complaint in the general population that occurs with a greater frequency in patients with Cushing's disease and is attributed to androgenetic alopecia, but it is rarely the presenting symptom.

Cushing's syndrome is a serious endocrine disease caused by chronic, autonomous, and excessive secretion of cortisol. The syndrome is associated with increased mortality and impaired quality of life because of the occurrence of comorbidities. These clinical complications include metabolic syndrome, consisting of systemic arterial hypertension, visceral obesity, impairment of glucose metabolism, and dyslipidaemia; musculoskeletal disorders, such as myopathy, osteoporosis, and skeletal fractures; neuropsychiatric disorders, such as impairment of cognitive function, depression, or mania; impairment of reproductive and sexual function; and dermatological manifestations, mainly represented by acne, hirsutism, and alopecia. Hypertension in patients with Cushing's syndrome has a multifactorial pathogenesis and contributes to the increased risk for myocardial infarction, cardiac failure, or stroke, which are the most common causes of death; risks of these outcomes are exacerbated by a prothrombotic diathesis and hypokalaemia. Neuropsychiatric disorders can be responsible for suicide. Immune disorders are common; immunosuppression during active disease causes susceptibility to infections, possibly complicated by sepsis, an important cause of death, whereas immune rebound after disease remission can exacerbate underlying autoimmune diseases. Prompt treatment of cortisol excess and specific treatments of comorbidities are crucial to prevent serious clinical complications and reduce the mortality associated with Cushing's syndrome.

Caprine herpesvirus 2 (CpHV-2) infection usually induces chronic malignant catarrhal fever (MCF) in sika deer (Cervus nippon), with the primary signs of weight loss, dermatitis and alopecia. Here, we report a case of CpHV-2-associated acute MCF in a sika deer herd raised in an intensive management system distant to the reservoir goats. Affected deer developed clinical signs of high fever (41 °C) followed by nasal discharge and lameness. Severe lesions of hemorrhage, necrosis and infiltration of lymphoid cells could readily be observed in the lung, kidney, heart valves and subcutaneous tissue surrounding a tendon. Etiologically, identical CpHV-2 specific DNA sequences were detected in peripheral blood lymphocyte (PBL) from the affected deer and reservoir goats. In summary, domestic goats were the reservoir of the CpHV-2, which is the causative agent of the outbreak of MCF in the three hinds. The disease was probably transmitted via aerosol infection. In addition, necrosis and inflammation in subcutaneous tissue surrounding a tendon was the reason for lameness. Therefore, MCF should be put into a differential diagnostic list when similar disease occurs in sika deer herds.

Demodex canis is a natural inhabiting mite of canine skin. Immunological disorder or genetic disorder induces the Demodex population to proliferate vigorously resulting in generalized demodicosis with consequent chronic immunosuppression. Signs of generalized demodicosis include alopecia, crysting, erythema, secondary pyoderma etc. Amitraz, an acaricide, is used conventionally for the treatment of generalized demodicosis. In many instances, the disease relapses due to the residual immunosuppression. The need of an immunorestorative therapy has been urged in generalized demodicosis. Two immunorestorative drugs, namely, Immuplus, a herbal drug, and T11TS, a sheep erythrocyte surface glycoprotein, has been used in two separate groups of dogs having generalized demodicosis and receiving Amitraz treatment. It was observed that though Amitraz treated group responded to the therapy showing increased E-rosettes and nonspecific cytotoxic efficacy of T-lymphocytes and decrease in phagocytic potential of macrophages, the groups treated with the immunotherapeutics like Immuplus and T11TS, responded better. However, the group treated with T11TS showed best recovery. These results emphasize the need for an immunorestorative therapy in generalized demodicosis and provide data in favor of T11TS as a better immunomodulator in comparison to Immuplus.

Chemotherapy-induced alopecia is a common and distressing adverse effect. In previous studies of scalp cooling to prevent chemotherapy-induced alopecia, conclusions have been limited. To evaluate whether use of a scalp cooling system is associated with a lower amount of hair loss among women receiving specific chemotherapy regimens for early-stage breast cancer and to assess related changes in quality of life. A prospective cohort study conducted at 5 US medical centers of women with stage I or II breast cancer receiving adjuvant or neoadjuvant chemotherapy regimens excluding sequential or combination anthracycline and taxane (106 patients in the scalp cooling group and 16 in the control group; 14 matched by both age and chemotherapy regimen). The study was conducted between August 2013 and October 2014 with ongoing annual follow-up for 5 years. Use of a scalp cooling system. Scalp cooling was initiated 30 minutes prior to each chemotherapy cycle, with scalp temperature maintained at 3°C (37°F) throughout chemotherapy and for 90 minutes to 120 minutes afterward. Self-estimated hair loss using the Dean scale was assessed 4 weeks after the last dose of chemotherapy by unblinded patient review of 5 photographs. A Dean scale score of 0 to 2 (≤50% hair loss) was defined as treatment success. A positive association between scalp cooling and reduced risk of hair loss would be demonstrated if 50% or more of patients in the scalp cooling group achieved treatment success, with the lower bound of the 95% CI greater than 40% of the success proportion. Quality of life was assessed at baseline, at the start of the last chemotherapy cycle, and 1 month later. Median follow-up was 29.5 months. Among the 122 patients in the study, the mean age was 53 years (range, 28-77 years); 77.0% were white, 9.0% were black, and 10.7% were Asian; and the mean duration of chemotherapy was 2.3 months (median, 2.1 months). No participants in the scalp cooling group received anthracyclines. Hair loss of 50% or less (Dean score of 0-2) was seen in 67 of 101 patients (66.3%; 95% CI, 56.2%-75.4%) evaluable for alopecia in the scalp cooling group vs 0 of 16 patients (0%) in the control group (P < .001). Three of 5 quality-of-life measures were significantly better 1 month after the end of chemotherapy in the scalp cooling group. Of patients who underwent scalp cooling, 27.3% (95% CI, 18.0%-36.6%) reported feeling less physically attractive compared with 56.3% (95% CI, 31.9%-80.6%) of patients in the control group (P = .02). Of the 106 patients in the scalp cooling group, 4 (3.8%) experienced the adverse event of mild headache and 3 (2.8%) discontinued scalp cooling due to feeling cold. Among women undergoing non-anthracycline-based adjuvant chemotherapy for early-stage breast cancer, the use of scalp cooling vs no scalp cooling was associated with less hair loss at 4 weeks after the last dose of chemotherapy. Further research is needed to assess outcomes after patients receive anthracycline regimens, longer-term measures of alopecia, and adverse effects. clinicaltrials.gov Identifier: NCT01831024.

White wax (WW) has been traditionally used to treat hair loss in China. However there has been no reporter WW and its extract responsible for hair growth-promoting effect on androgenetic alopecia. In this paper, we examined the hair growth-promoting effects of WW and policosanol of white wax (WWP) on model animal of androgenetic alopecia and the potential target cell of WW and WWP. WW (1, 10 and 20%) and WWP (0.5, 1 and 2%) were applied topically to the backs of mice. Finasteride (2%) was applied topically as a positive control. MTS assays were performed to evaluate cell proliferation in culture human follicle dermal papilla cells (HFDPCs). The inhibition of WW and WWP for 5α- reductase were tested in Vitro. Results showed more lost hairs were clearly seen in mice treated with TP only and TP plus vehicle. Mice which received TP plus WW and WWP showed less hair loss. WW and WWP showed an outstanding hair growth-promoting activity as reflected by the follicular length, follicular density, A/T ratio, and hair bulb diameter. The optimal treatment effect was observed at 10% WW and 1% WWP, which were better than 2% finasteride treatment. MTS assay results suggested that WW and WWP remarkably increased the proliferation of HFDPCs. Inhibitor assay of 5α- reductase showed that WW and WWP inhibited significantly the conversion of testosterone to dihydrotesterone, and the IC 50 values of WW and WWP were higher than that of finasteride. In Conclusion, WW and WWP could act against testosterone-induced alopecia in mice, and they promoted hair growth by inhibiting 5α-reductase activity and HFDPCs proliferation. DPCs is the target cell of WW and WWP. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

Canine noninflammatory alopecia (CNA) is a heterogeneous group of skin diseases with different underlying pathogenesis. The therapeutic approach is challenging, and new options for treatment are desirable. To test the clinical efficacy of low-level laser therapy (LLLT) on hair regrowth in CNA. Seven dogs of different ages, breeds and genders with a clinical and histopathological diagnosis of noninflammatory alopecia. Each dog was treated twice weekly for a maximum of 2 months with a therapeutic laser producing the following three different wavelengths emerging simultaneously from 21 foci: 13 × 16 mW, 470 nm; 4 × 50 mW, 685 nm; and 4 × 200 mW, 830 nm. The fluence given was 3 J/cm(2) , frequency 5 Hz, amplitude of the irradiated area was 25 cm(2) and application time was 1.34 min. A predetermined alopecic area was left untreated and served as a control area. From one dog, post-treatment biopsies of treated and untreated sites were obtained for histological evaluation of hair density and the percentage of haired and nonhaired follicles. At the end of the study, coat regrowth was greatly improved in six of seven animals and improved in one of seven. By morphometry, the area occupied by hair follicles was 18% in the treated sample and 11% in the untreated one (11%); haired follicles were (per area) 93% in the treated sample and only 9% in the control sample. Our clinical and histological data document promising effects of LLLT on hair regrowth in CNA. Further studies investigating the biological mechanism underlying the effect of LLLT on hair follicle cycling are warranted. © 2014 ESVD and ACVD.

Despite NUDT15 variants showing significant association with thiopurine-induced adverse events (AEs) in Asians, it remains unclear which variants of NUDT15 or whether additional genetic variants should be tested to predict AEs. To clarify the best pharmacogenetic test to be used clinically, we performed association studies of NUDT15 variants and haplotypes with AEs, genome-wide association study (GWAS) to discover additional variants, and ROC analysis to select the model to predict severe AEs. Overall, 2630 patients with inflammatory bowel disease (IBD) were enrolled and genotyped for NUDT15 codon 139; 1291 patients were treated with thiopurines. diplotypes were analyzed in 970 patients, and GWASs of AEs were performed with 1221 patients using population-optimized genotyping array and imputation. We confirmed the association of NUDT15 p.Arg139Cys with leukopenia and alopecia (p = 2.20E-63, 1.32E-69, OR = 6.59, 12.1, respectively), and found a novel association with digestive symptoms (p = 6.39E-04, OR = 1.89). Time to leukopenia was significantly shorter, and when leukopenia was diagnosed, thiopurine doses were significantly lower in Arg/Cys and Cys/Cys than in Arg/Arg. In GWASs, no additional variants were found to be associated with thiopurine-induced AEs. Despite strong correlation of leukopenia frequency with estimated enzyme activities based on the diplotypes (r 2  = 0.926, p = 0.0087), there were no significant differences in the AUCs of diplotypes from those of codon 139 to predict severe AEs (AUC = 0.916, 0.921, for acute severe leukopenia, AUC = 0.990, 0.991, for severe alopecia, respectively). Genotyping of NUDT15 codon 139 was sufficient to predict acute severe leukopenia and alopecia in Japanese patients with IBD.

Generalized discoid lupus erythematosus (GDLE) is a newly recognized canine variant of chronic cutaneous lupus erythematosus (CLE) that is not well characterized. We report herein the signalment, clinical signs, treatment outcome, histopathology and immunological findings of 10 dogs with GDLE. Inclusion criteria were: (i) a >3 month history of generalized skin lesions indicating a chronic or recurrent nature; (ii) skin lesions resembling those of human GDLE; (iii) histopathology of CLE (lymphocyte-rich interface dermatitis). Direct immunofluorescence (IF) and antinuclear antibody serology were investigated whenever possible. Various breeds were affected in their mid- to late adulthood. Selection criteria of generalized multifocal, annular ("discoid") to polycyclic plaques with pigment changes, erythematous margin, adherent scaling, follicular plugging and central alopecia were shown in all dogs. In nine dogs, plaques contained mild to moderate central scarring with depigmentation and/or hyperpigmentation. There were no dogs in which the disease progressed to systemic lupus erythematosus within a median follow-up of 2.5 years. Per inclusion criteria, interface dermatitis occurred with basement membrane zone (BMZ) thickening, suprabasal apoptosis and/or dermal fibrosis in some dogs. Infundibular interface folliculitis was common; it sometimes transitioned to mural folliculitis in lower follicle segments, and occurred with follicular and sebaceous gland atrophy. The direct IF revealed patchy deposition of immunoglobulin IgG and IgM at the BMZ. Lesions responded to a variety of treatments, including ciclosporin, hydroxychloroquine, topical tacrolimus and tetracycline/niacinamide. Relapses were common after medications were tapered. These observations support the existence of a canine homologue of human GDLE. © 2016 ESVD and ACVD.

Background: The variable success of topical minoxidil in the treatment of androgenic alopecia has led to the hypothesis that other pathways could mediate this form of hair loss, including infection and/or microinflammation of the hair follicles. In this study, we prepared a multimodal microemulsion comprising minoxidil (a dihydrotestosterone antagonist), diclofenac (a nonsteroidal anti-inflammatory agent), and tea tree oil (an anti-infective agent). We investigated the stability and physicochemical properties of this formulation, and its therapeutic efficacy compared with a formulation containing minoxidil alone in the treatment of androgenic alopecia. Methods: We developed a multimodal oil/water (o/w) microemulsion, a formulation containing minoxidil alone, and another containing vehicle. A three-phase diagram was constructed to obtain the optimal concentrations of the selected oil, surfactant, and cosurfactant. Thirty-two men aged 18–30 years were randomized to apply 1 mL of microemulsion containing the multimodal formulation (formulation A, n = 11), minoxidil alone (formulation B, n = 11) or placebo (formulation C, n = 10) twice daily to the affected area for 32 weeks. Efficacy was evaluated by mean hair count, thickness, and weight on the targeted area of the scalp. Global photographs were taken, changes in the area of scalp coverage were assessed by patients and external investigators, and the benefits and safety of the study medications were evaluated. The physical stability of formula A was examined after a shelf storage period of 24 months. Results: Formulation A achieved a significantly superior response than formulations B and C in terms of mean hair count (P < 0.001), mean hair weight (P < 0.001), and mean hair thickness (P < 0.05). A patient self-assessment questionnaire demonstrated that the multimodal minoxidil formulation significantly (P < 0.001) slowed hair loss, increased hair growth, and improved appearance, and showed no appreciable side effects, such as itching and/or inflammation of the scalp compared with the minoxidil alone and placebo formulations. These improvements were in agreement with the photographic assessments made by the investigators. Formula A was shown to be an o/w formulation with consistent pH, viscosity, specific gravity, and homogeneity, and was physically stable after 24 months of normal storage. Conclusion: A multimodal microemulsion comprising minoxidil, diclofenac, and tea tree oil was significantly superior to minoxidil alone and placebo in terms of stability, safety, and efficacy, and achieved an earlier response in the treatment of androgenic alopecia compared with minoxidil alone in this 32-week pilot study.

[Hormones and hair growth].

PubMed

Trüeb, R M

With respect to the relationship between hormones and hair growth, the role of androgens for androgenetic alopecia (AGA) and hirsutism is best acknowledged. Accordingly, therapeutic strategies that intervene in androgen metabolism have been successfully developed for treatment of these conditions. Clinical observations of hair conditions involving hormones beyond the androgen horizon have determined their role in regulation of hair growth: estrogens, prolactin, thyroid hormone, cortisone, growth hormone (GH), and melatonin. Primary GH resistance is characterized by thin hair, while acromegaly may cause hypertrichosis. Hyperprolactinemia may cause hair loss and hirsutism. Partial synchronization of the hair cycle in anagen during late pregnancy points to an estrogen effect, while aromatase inhibitors cause hair loss. Hair loss in a causal relationship to thyroid disorders is well documented. In contrast to AGA, senescent alopecia affects the hair in a diffuse manner. The question arises, whether the hypothesis that a causal relationship exists between the age-related reduction of circulating hormones and organ function also applies to hair and the aging of hair.

The novel photo-sharing social networking platform, Instagram, has an impressive following of 75 million daily users, with a predominantly younger and female demographic. This study investigated the presence of dermatology-related content on Instagram. The most popular professional dermatological organizations, dermatology journals, and dermatology related patient advocate groups on Facebook and Twitter, determined from a prior study, were searched for established profiles on Instagram. In addition, dermatology-related terms (i.e. dermatology, dermatologist, alopecia, eczema, melanoma, psoriasis, and skin cancer) and dermatology-related hashtags (i.e. #dermatology, #dermatologist, #melanoma, #acne, #psoriasis, and #alopecia) were searched. None of the top ten dermatological journals or professional dermatological organizations were found on Instagram. Although only one of the top ten patient advocate groups related to dermatology conditions, Melanoma Research Foundation, had an Instagram presence, there were many private offices, cosmetic products, and some patient advocacy groups. This novel social networking platform could grant dermatology journals and other professional organizations a unique opportunity to reach younger demographic populations, particularly women, with the potential for true educational and life-changing impact.

Given the hypothesis that microparticles can penetrate the skin barrier along the transfollicular route, this work aimed to obtain and characterise chitosan microparticles loaded with minoxidil sulphate (MXS) and to study their ability to sustain the release of the drug, attempting a further application utilising them in a targeted delivery system for the topical treatment of alopecia. Chitosan microparticles, containing different proportions of MXS/polymer, were prepared by spray drying and were characterised by yield, encapsulation efficiency, size and morphology. Microparticles selected for further studies showed high encapsulation efficiency (∼82%), a mean diameter of 3.0 µm and a spherical morphology without porosities. When suspended in an ethanol/water solution, chitosan microparticles underwent instantaneous swelling, increasing their mean diameter by 90%. Release studies revealed that the chitosan microparticles were able to sustain about three times the release rate of MXS. This feature, combined with suitable size, confers to these microparticles the potential to target and improve topical therapy of alopecia with minoxidil.

Thyroid dysfunction affects 1–4% of the population worldwide, causing defects including neurodevelopmental disorders, dwarfism and cardiac arrhythmia. Here, we show that KCNQ1 and KCNE2 form a TSH-stimulated, constitutively-active, thyrocyte K+ channel required for normal thyroid hormone biosynthesis. Targeted disruption of Kcne2 impaired thyroid iodide accumulation up to 8-fold, impaired maternal milk ejection and halved milk T4 content, causing hypothyroidism, 50% reduced litter size, dwarfism, alopecia, goiter, and cardiac abnormalities including hypertrophy, fibrosis, and reduced fractional shortening. The alopecia, dwarfism and cardiac abnormalities were alleviated by T3/T4 administration to pups, by supplementing dams with T4 pre- and postpartum, or by pre-weaning surrogacy with Kcne2+/+ dams; conversely these symptoms were elicited in Kcne2+/+ pups by surrogacy with Kcne2−/− dams. The data identify a critical thyrocyte K+ channel, provide a possible novel therapeutic avenue for thyroid disorders, and predict an endocrine component to some previously-identified KCNE2- and KCNQ1-linked human cardiac arrhythmias.

This study was conducted to evaluate the effect of Grateloupia elliptica, a seaweed native to Jeju Island, Korea, on the prevention of hair loss. When immortalized rat vibrissa dermal papilla cells were treated with extract of G. elliptica, the proliferation of dermal papilla cells significantly increased. In addition, the G. elliptica extract significantly inhibited the activity of 5α-reductase, which converts testosterone to dihydrotestosterone (DHT), a main cause of androgenetic alopecia. On the other hand, the G. elliptica extract promoted PGE2 production in HaCaT cells in a dose-dependent manner. The G. elliptica extract exhibited particularly high inhibitory effect on LPS-stimulated IL-12, IL-6, and TNF-α production in lipopolysaccharide (LPS)-stimulated bone marrow-derived dendritic cells. The G. elliptica extract also showed inhibitory activity against Pityrosporum ovale, a main cause of dandruff. These results suggest that G. elliptica extract has the potential to treat alopecia via the proliferation of dermal papilla, 5α-reductase inhibition, increase of PGE2 production, decrease of LPS-stimulated pro-inflammatory cytokines and inhibitory activity against Pityrosporum ovale.

2018-01-01

Folliculitis decalvans (FD) is classified as a primary neutrophilic cicatricial alopecia, and is estimated to account for approximately 10% of all cases of primary cicatricial alopecia. The role of dysfunctional immune activity and the presence of bacteria, particularly Staphylococcus aureus, appear pivotal. We describe a 26-year-old man with a 4-year history of FD that was recalcitrant to numerous systemic and topical therapies, whose disease was virtually cleared during a follow-up of 25 months following a course of treatment with systemic photodynamic therapy (PDT) using ultraviolet light (100-140 J/cm 2 ) with porfimer sodium 1 mg/kg as monotherapy. This is the first report of the use of systemic PDT as a treatment for FD. Systemic PDT has potent antibacterial effects with little or no resistance. In addition, systemic PDT provides local immunomodulation and improved scar healing. Significant adverse effects following systemic PDT with appropriate aftercare are rare. This case demonstrates that systemic PDT is a useful therapy option in the treatment of recalcitrant FD. © 2017 British Association of Dermatologists.

Residual groups of hair follicles and unusual "tufts" of multiple hairs emerging from single follicular openings have been described in scarring alopecia associated with staphylococcal infection. Various mechanisms have been proposed to explain these findings. Histological study of four cases suggests that retention of telogen hairs through several hair cycles may be responsible for this phenomenon.

Background: Microbial keratitis is a potentially vision threatening condition worldwide. Knowing the predisposing factors and etiologic microorganism can help control and prevent this problem. This is the first study of its kind in Kingdom of Bahrain. Objective: To study the profile of microbial keratitis in Bahrain with special focus on risk factors, clinical outcome and microbilogical results. Methods: A retrospective analysis of all patients admitted in Salmaniya Medical Complex over a period of three years from January 2005 to January 2007 was performed. A total of 285 patients with keratitis were analysed. Non infectious corneal ulceration were excluded. Data collected from medical records were demographic features, predisposing factors, history of corneal trauma, associated ocular conditions, visual acuity at the time of presentation and the clinical course. Predisposing risk factors measured were contact lens use, presence of blepharitis, diabetes, lid abnormalities, dry eyes, keratoplasty and refractive surgery. For contact lens wearers any contact lens related risk factors that can lead to keratitis were measured. Pearson's chi-square test was used to carry out statistical analysis wherever required. Results: Contact lens wear, as a risk factor for microbial keratitis, formed 40% of the total study population. Other risk factors identified were dry eyes 24 cases (8%), 10 blepharitis (3%), 22 trauma (8%), abnormal lid position 14 cases (5%). 6 patients keratitis in a graft (2%), 3 had refractive surgery (1%). The most common causative organism isolated was pseudomonas aeroginosa (54%) followed by streptococcus 12%, staph 10%, other organisms 6%. 95% of contact lens wearers had pseudomonas Aeroginosa. This was statistically significant (p< 0.0001). The vast majority, 92% healed with scarring. 1% needed therapeutic keratoplasty and 7% lost to follow up. Risk factors in contact lens wearers were; 41 patients (36%) slept with the contact lenses. 12 (8%) had contact lens related trauma and 8 (7%) had poor hygiene. Sleeping with the contact lenses was statistically significant (p< 0.0001). Conclusion & Recommendation: Contact lens wear is the major risk factor for microbial keratitis in Bahrain. Pseudomonas aeroginosa was the commonest bacteria isolated. Sleeping with the contact lenses is the major risk factor among contact lens wearers. Majority of keratitis patients resulted in permanent scarring on the cornea. Educating the public, especially on contact lens care and precaution, can help reduce this visual morbidity.

Our previous observations clarified that Graves' disease (GD) is the most frequent autoimmune disease in patients with alopecia areata (AA), and 42.7% of patients with AA were positive for thyrotropin receptor antibody (TRAb). A class II HLA haplotype DRB1 ∗ 15:01-DQB1 ∗ 06:02 was suggested to contribute to autoimmunity against the thyroid gland in AA. To further clarify the genetic factors contributing to organ specificity in autoimmune diseases, we studied the contribution of non-HLA genes to organ specificity in GD and AA. A high frequency of AA (13.4%) was observed in patients with GD, indicating strong phenotypic association between GD and AA. CTLA4 and TSHR were significantly associated with GD (Pc=0.007 and Pc<0.002, respectively), but not with AA, even in TRAb-positive patients. The difference in the association between GD and AA suggests that the CTLA4 and TSHR are not main factors contributing to determining common genetic basis among GD and AA.

Histopathological examination demonstrated two types of melanocytes, spindle-shaped and ovoid cells, with abundant melanin aggregated around the upper part of the pilosebaceous apparatus. Fibrous, thick collagen bundles were also seen surrounding the upper part of the small hair follicles. There was no infiltration of melanocytes or lymphocytes in the lower dermis or adipose tissue. Based on these findings, a diagnosis of blue nevus, cellular type, was made. Giant cellular blue nevi on the scalp are rare, and 11 cases reported in the published work have shown characteristic features such as hair loss and cranial invasion of nevus cells. It should be noted that melanocytes of giant blue nevi have a high potential to damage other organs such as underlying bone and hair follicles. The patient also showed a typical lesion of alopecia areata on the left temporal which was successfully treated with topical corticosteroid. © 2010 Japanese Dermatological Association.

The prevalence of androgenic alopecia (AGA) increases with age and it affects both men and women. Patients diagnosed with AGA may experience decreased quality of life, depression, and feel self-conscious. There are a variety of therapeutic options ranging from prescription drugs to non-prescription medications. Currently, AGA involves an annual global market revenue of US$4 billion and a growth rate of 1.8%, indicating a growing consumer market. Although natural and synthetic ingredients can promote hair growth and, therefore, be useful to treat AGA, some of them have important adverse effects and unknown mechanisms of action that limit their use and benefits. Biologic factors that include signaling from stem cells, dermal papilla cells, and platelet-rich plasma are some of the current therapeutic agents being studied for hair restoration with milder side effects. However, most of the mechanisms exerted by these factors in hair restoration are still being researched. In this review, we analyze the therapeutic agents that have been used for AGA and emphasize the potential of new therapies based on advances in stem cell technologies and regenerative medicine.

p53 is a transcription factor mediating a variety of biological responses including apoptotic cell death. p53 was recently shown to control apoptosis in the hair follicle induced by ionizing radiation and chemotherapy, but its role in the apoptosis-driven physiological hair follicle regression (catagen) remains to be elucidated. Here, we show that p53 protein is strongly expressed and co-localized with apoptotic markers in the regressing hair follicle compartments during catagen. In contrast to wild-type mice, p53 knockout mice show significant retardation of catagen accompanied by significant decrease in the number of apoptotic cells in the hair matrix. Furthermore, p53 null hair follicles are characterized by alterations in the expression of markers that are encoded by p53 target genes and are implicated in the control of catagen (Bax, Bcl-2, insulin-like growth factor binding protein-3). These data suggest that p53 is involved in the control of apoptosis in the hair follicle during physiological regression and imply that p53 antagonists may be useful for the management of hair growth disorders characterized by premature entry into catagen, such as androgenetic alopecia, alopecia areata, and telogen effluvium.

Context Conventional chemotherapy leads to multiple adverse mucocutaneous complications including oral mucositis, alopecia, ocular toxicity, and onycholysis. Limited pharmacologic interventions are available for preventing these clinical problems. Objectives This study aimed to critically review the role of cryotherapy (regional hypothermia) for alleviating these adverse symptoms. Methods A narrative review was performed, with an emphasis on randomized controlled trials. A comprehensive search using PubMed, Ovid, Embase, and MEDLINE® was completed. References of all cited articles also were reviewed. Data from the review were comprised of articles published between 1970 to May 2013. Results Available evidence suggests that regional hypothermia decreases the burden of chemotherapy-related oral mucositis, alopecia, ocular toxicity, and onycholysis. The major limitations of studies include the absence of blinded control groups and variable clinical endpoints. Conclusion Regional hypothermia decreases the burden of these four chemotherapy-induced complications and is well tolerated. More research is needed to determine what subgroups of cancer patients are most likely to respond to different types of regional hypothermia, the ideal duration of cooling needed, and to further improve the ease of use of the cooling devices.

Alopecia areata (AA) is a prevalent autoimmune disease with ten known susceptibility loci. Here we perform the first meta-analysis in AA by combining data from two genome-wide association studies (GWAS), and replication with supplemented ImmunoChip data for a total of 3,253 cases and 7,543 controls. The strongest region of association is the MHC, where we fine-map 4 independent effects, all implicating HLA-DR as a key etiologic driver. Outside the MHC, we identify two novel loci that exceed statistical significance, containing ACOXL/BCL2L11(BIM) (2q13); GARP (LRRC32) (11q13.5), as well as a third nominally significant region SH2B3(LNK)/ATXN2 (12q24.12). Candidate susceptibility gene expression analysis in these regions demonstrates expression in relevant immune cells and the hair follicle. We integrate our results with data from seven other autoimmune diseases and provide insight into the alignment of AA within these disorders. Our findings uncover new molecular pathways disrupted in AA, including autophagy/apoptosis, TGFß/Tregs and JAK kinase signaling, and support the causal role of aberrant immune processes in AA.

Alopecia is an exceedingly prevalent problem effecting men and women of all ages. The standard of care for alopecia involves either transplanting existing hair follicles to bald areas or attempting to stimulate existing follicles with topical and/or oral medication. Yet, these treatment options are fraught with problems of cost, side effects, and, most importantly, inadequate long-term hair coverage. Innovative cell-based therapies have focused on the dermal papilla cell as a way to grow new hair in previously bald areas. However, despite this attention, many obstacles exist, including retention of dermal papilla inducing ability and maintenance of dermal papilla productivity after several passages of culture. The use of adipocyte lineage cells, including adipose-derived stem cells, has shown promise as a cell-based solution to regulate hair regeneration and may help in maintaining or increasing dermal papilla cells inducing hair ability. In this review, we highlight recent advances in the understanding of the cellular contribution and regulation of dermal papilla cells and summarize adipocyte lineage cells in hair regeneration.

The success of scalp cooling in preventing or reducing chemotherapy-induced alopecia (CIA) is highly variable between patients and chemotherapy regimens. The outcome of hair preservation is often unpredictable and depends on various factors. Methods. We performed a structured search of literature published from 1970 to February 2012 for articles that reported on factors influencing the effectiveness of scalp cooling to prevent CIA in patients with cancer. Results. The literature search identified 192 reports, of which 32 studies were considered relevant. Randomized studies on scalp cooling are scarce and there is little information on the determinants of the result. The effectiveness of scalp cooling for hair preservation depends on dose and type of chemotherapy, with less favorable results at higher doses. Temperature seems to be an important determinant. Various studies suggest that a subcutaneous scalp temperature less than 22 °C is required for hair preservation. Conclusions. The effectiveness of scalp cooling for hair preservation varies by chemotherapy type and dose, and probably by the degree and duration of cooling.

Hair restoration surgery: challenges and solutions

Hair loss is a common problem affecting both men and women. The most frequent etiology is androgenetic alopecia, but other causes of hair loss such as trauma, various dermatologic diseases, and systemic diseases can cause alopecia. The loss of hair can have profound effects on one’s self esteem and emotional well-being, as one’s appearance plays a role in the work place and interpersonal relationships. It is therefore not surprising that means to remedy hair loss are widely sought. Hair transplant surgery has become increasingly popular, and the results that we are able to create today are quite remarkable, providing a natural appearance when the procedure is performed well. In spite of this, hair transplant surgery is not perfect. It is not perfect because the hair transplant surgeon is still faced with challenges that prevent the achievement of optimal results. Some of these challenges include a limit to donor hair availability, hair survival, and ways to conceal any evidence of a surgical procedure having taken place. This article examines some of the most important challenges facing hair restoration surgery today and possible solutions to these challenges. PMID:26203266

Excimer laser: a module of the alopecia areata common protocol.

PubMed

McMichael, Amy J

2013-12-01

Alopecia areata (AA) is an autoimmune condition characterized by T cell-mediated attack of the hair follicle. The inciting antigenic stimulus is unknown. A dense perbulbar lymphocytic infiltrate and reproducible immunologic abnormalities are hallmark features of the condition. The cellular infiltrate primarily consists of activated T lymphocytes and antigen-presenting Langerhans cells. The xenon chloride excimer laser emits its total energy at the wavelength of 308 nm and therefore is regarded as a "super-narrowband" UVB light source. Excimer laser treatment is highly effective in psoriasis, another T cell-mediated disorder that shares many immunologic features with AA. The excimer laser is superior in inducing T cell apoptosis in vitro compared with narrowband UVB, with paralleled improved clinical efficacy. The excimer laser has been used successfully in patients with AA. In this context, evaluation of the potential benefit of 308-nm excimer laser therapy in the treatment of AA is clinically warranted. Herein, the use of a common treatment protocol with a specifically designed module to study the outcome of excimer laser treatment on moderate-to-severe scalp AA in adults is described.

The pathologic findings in Central Centrifugal Cicatricial Alopecia (CCCA) have not been studied systematically in horizontal sections. Our objective was to establish the pathologic features, and their frequency in horizontal sections of scalp biopsies obtained from patients with clinically and histologically proven CCCA. Serial horizontal sections of 51 cases were evaluated retrospectively. All biopsies were assessed at 4 levels and at least on 24 horizontal sections. The most common pathologic findings were follicular miniaturization (81% of the cases); premature desquamation of the inner root sheath (96%), focal preservation of the sebaceous glands (94%), which in most of these cases appeared as surrounding "in a hug" an intact vellus follicle; compound follicular structures with perifollicular fibrosis and/or inflammation (89%), lamellar hyperkeratosis/parakeratosis in the hair canal (79%), absent or mild inflammation (77%), and naked hair shafts (68%). Horizontal sections are useful in CCCA to identify early or focal disease and to provide the clinician with better information on the presence of follicular miniaturization, inflammation, and scarring, which can be used to tailor the treatment to the individual patient.

Skin ageing and gender influences on the scalp have been seldom studied. We revisited the changes in the interfollicular scalp. The study was performed on a population of 650 volunteers (300 women and 350 men) for over 7 years. Three age groups were selected in both genders, namely, subjects aged 20–35, 50–60, and 60–70 years. The hair status was further considered according to nonalopecic and alopecic patterns and severity (discrete, moderate, and severe). Biopsies from the parietal area were processed for immunohistochemistry. Stromal cells were distinguished according to the presence of vimentin, Factor XIIIa, CD117, and versican. Blood and lymphatic vessels were highlighted by Ulex europaeus agglutinin-1 and human podoplanin immunoreactivities, respectively. Actinic elastosis was identified by the lysozyme coating of elastic fibres. The epidermis was explored using the CD44 variant 3 and Ki67 immunolabellings. Biplot analyses were performed. Immunohistochemistry revealed a prominent gender effect in young adults. Both Factor XIIIa+ dermal dendrocytes and the microvasculature size decreased with scalp ageing. Alopecia changes mimicked stress-induced premature senescence. PMID:24455724

Juvenile sterile granulomatous dermatitis and lymphadenitis is a rare immune-mediated skin disease in young dogs. History, signalment, diagnostics, treatment, and outcome in 10 dogs are described. The age ranged from 8 - 36 weeks. The lymph nodes were enlarged in all dogs, especially the mandibular and prescapular lymph nodes. Systemic signs including fever were present in 8 dogs. Seven dogs suffered from blepharitis and painful edema of the muzzle with hemorrhagic discharge, pustules and papules. Cytology of pustules and lymph node aspirates revealed a pyogranulomatous inflammation. In 7 cases the diagnosis of juvenile sterile granulomatous dermatitis and lymphadenitis was confirmed by histology. Nine dogs were treated with prednisolone (0.5 - 1.25 mg/kg BID), H2-receptor antagonists and analgetics; all dogs were treated with antibiotics. Four dogs were treated with eye ointment containing antibiotics and glucocorticoids. The prednisolone dosage was tapered over 3 - 8 weeks. One dog had a relapse.

Hair follicle characteristics as early marker of Type 2 Diabetes.

Type 2 Diabetes mellitus (DM2) includes a continuum of metabolic disorders characterized by hyperglycemia that causes several chronic long-term complications such as coronary artery disease, peripheral arterial disease, nephropathy, and neuropathy. The hair follicle could reveal signs of early vascular impairment, yet its relationship to early metabolic injuries has been largely ignored. We propose that in earlier stages of the continuum of DM2-related metabolic disorders, a group of susceptible patients who do not yet meet the diagnostic criteria to be considered as persons with DM2 may present chronic vascular impairment and end organ damage, including hair follicle damage, which can be evaluated to identify an early risk marker. This hypothesis is based in the association found between insulin resistance and alopecia in non-diabetic persons, and the hair loss on the lower limbs as a manifestation of long-term peripheral arterial disease among subjects with DM2. In order to test this hypothesis, studies are required to evaluate if hair follicle characteristics are related to and can predict hyperglycemic complications, and if they do so, which feature of the hair follicle, such as hair growth, best characterizes such DM2-related conditions. If this hypothesis were proven to be true, significant advances towards a personalized approach for early prevention strategies and management of DM2 would be made. By focusing on the hair follicles, early stages of metabolic-related organ damage could be identified using non-invasive low-cost techniques. In so doing, this approach could provide early identification of DM2-susceptible individuals and lead to the early initiation of adequate primary prevention strategies to reduce or avoid the onset of large internal organ damage.

Systemic effects of Leucaena leucocephala ingestion on ringtailed lemurs (Lemur catta) at Berenty Reserve, Madagascar.

Leucaena (Leucaena leucocephala) is a leguminous tree that is nutritious forage for domestic livestock when ingested in limited amounts. Unfortunately, leucaena contains mimosine, a plant amino acid, that can be toxic when ingested at higher concentrations. Reported toxic effects include alopecia (fur loss), poor body condition, infertility, low birth weight, thyroid gland dysfunction, and organ toxicity. Originally native to Mexico and Central America, leucaena has been introduced throughout the tropics, including Berenty Reserve, Madagascar where it was planted as supplemental browse for livestock. In Berenty, a seasonal syndrome of alopecia in ringtailed lemurs (Lemur catta) is associated with eating leucaena. Although much is known about the toxic effects of leucaena and mimosine on domestic animals and humans, the systemic effects on wildlife had not been studied. In a comparison of lemurs that include leucaena in their diet and those that do not, we found that animals that ingest leucaena absorb mimosine but that ingestion does not affect body condition, cause kidney or liver toxicity, or affect the intestinal tract. Alopecia is due to mimosine's interference of the hair follicle cycle. Leucaena ingestion is associated with higher serum albumin, α-tocopherol, and thyroxine concentrations, suggesting that leucaena may provide some nutritional benefit and that lemurs can detoxify and convert mimosine to a thyroid stimulating metabolite. The primary conservation consequence of leucaena ingestion at Berenty may be increased infant mortality due to the infants' inability cling to their alopecic mothers. The widespread introduction of leucaena throughout the tropics and its rapid spread in secondary forest conditions mean that many other leaf-eating mammals may be including this tree in their diet. Thus, exposure to leucaena should be considered when wildlife health is being evaluated, and the potential effects on wildlife health should be considered when contemplating leucaena introduction into or near wildlife habitat. © 2015 Wiley Periodicals, Inc.

Vitamin D Level in Alopecia Areata.

Alopecia areata (AA) is an immune-mediated disease in which autoantigens play an important part in activating T-lymphocytes. Vitamin D has been associated with various autoimmune diseases, and Vitamin D receptors are strongly expressed in hair follicles and their expression in keratinocytes is necessary for the maintenance of the normal hair cycle. The aim of this study was to find the association between Vitamin D level and AA. This was a hospital-based cross-sectional study in which 50 patients with clinically and trichoscopically diagnosed AA cases, and 35 healthy age- and sex-matched controls were studied in summer months. Blood samples were taken from both cases as well as controls and samples were immediately processed by centrifugation (4000 rpm) at room temperature. Plasma 25-hydroxyvitamin D (25(OH)D) was analyzed by chemiluminescence method. A deficiency in Vitamin D was defined as serum 25(OH)D concentrations <30 ng/ml. The mean body mass index in cases was 20.96 ± 1.91, whereas in controls, it was 21.37 ± 1.70 ( P = 0.31). The mean serum 25(OH)D levels of AA patients was 16.6 ± 5.9 ng/ml, whereas in control group, the mean level was 40.5 ± 5.7, the difference being statistically significant ( P < 0.001). A significant negative correlation was found between severity of alopecia tool score and Vitamin D level ( P < 0.001; r = -0.730) and also between the number of patches and Vitamin D level ( P < 0.001, r = -0.670). In our study, we found that the levels of 25(OH)D were low in AA patients when compared to healthy controls. Furthermore, there was a significant negative correlation between the levels of serum Vitamin D and severity of AA. Thus, the study suggests the role of Vitamin D in pathogenesis of AA and hence a possible role of Vitamin D supplementation in treatment of same. Our study was limited by the lesser number of patients and lack of therapeutic trial of Vitamin D for these patients.

Alopecia areata (AA) is an organ-specific autoimmune disease characterized by T-cell infiltrates and cytokine production. T-helper 17 (Th17) cells are crucially involved in the pathogenesis of autoimmune diseases. Our aim was to assess the association of Th17 with AA. We examined interleukin (IL)-17, IL-21, IL-22, IL-6, and tumor necrosis factor-alpha (TNF-α) levels in the serum of patients with AA and studied their association with clinical type and severity of AA. The serum concentrations of IL-17, IL-21, IL-22, IL-6, and TNF-α were measured in 47 patients with AA and 40 healthy controls. The clinical type of AA was determined, and the severity of hair loss was assessed in accordance with the Alopecia Areata Investigational Assessment Guideline criteria. The serum concentrations of IL-17, IL-21, IL-22, IL-6, and TNF-α were significantly higher in patients with AA as compared with healthy controls (mean: IL-17 33.23 ± 11.58 vs. 4.62 ± 1.88 pg/ml; P = 0.000, IL-21 62.10 ± 6.11 vs. 48.38 ± 3.31 pg/ml; P = 0.000, IL-22 19.27 ± 3.36 vs. 7.09 ± 1.62 pg/ml; P = 0.000, IL-6 17.18 ± 3.08 vs. 4.59 ± 1.66 pg/ml; P = 0.000, TNF-α 19.94 ± 3.59 vs. 9.95 ± 2.42 pg/ml; P = 0.000, respectively). There were significant positive correlations between serum IL-17, TNF-α, and disease severity. There was also significant positive correlation between serum IL-22 and duration of AA. Our results showed high serum levels of Th17 cytokines among patients with AA that may suggest a functional role of these cytokines in the pathogenesis of this important skin disease. It could also provide the rationale for new treatment strategies in AA. © 2015 The International Society of Dermatology.

Topical Minoxidil: Systematic Review and Meta-Analysis of Its Efficacy in Androgenetic Alopecia.

2015-01-01

Topical minoxidil has become a mainstay in the treatment of androgenetic alopecia (AGA). Despite being a longstanding treatment for AGA, relatively few reviews of its efficacy have been published. The current study sought to synthesize the available efficacy data by performing a systematic review of the literature and conducting random-effects pairwise meta-analyses for the outcomes percent increase in hair count from baseline, investigator assessment, and patient self-assessment. Results showed that minoxidil is more effective than placebo in promoting total and nonvellus hair growth (mean difference [MD], 16.68; 95% confidence interval [CI], 9.34-24.03 and MD, 20.90; 95% CI, 9.07-32.74). A significantly higher proportion of participants in the minoxidil group had greater hair growth than participants in the placebo group as judged by both investigators and self-reports (relative risk [RR], 2.28; 95% CI, 1.58-3.31 and RR, 1.56; 95% CI, 1.34-1.80). Despite significant clinical efficacy, cosmetically acceptable results are present in only a subset of patients. Compliance is thought to be a major limiting factor and is being addressed by novel formulations and combinations.
