REVIEW
W Harth
Psychosomatic disorders of the scalp have some special characteristics due to the visibility, possible stigmatization, and amount/patterns of hair. Of practical relevance is trichotillomania, which is now classified as an obsessive-compulsive disorder (OCD). Patients who are obsessed with normal physiological hair loss represent a further psychodermatological challenge. Psychosomatic therapy includes basic psychosomatic care, behavior therapy, or treatment with psychopharmaceuticals.

Neurodegeneration, the progressive death of neurons, loss of brain function, and cognitive decline is an increasing problem for senior populations. Its causes are poorly understood and therapies are largely ineffective. Neurons, with high energy and oxygen requirements, are especially vulnerable to detrimental factors, including age-related dysregulation of biochemical pathways caused by altered expression of multiple genes. GHK (glycyl-l-histidyl-l-lysine) is a human copper-binding peptide with biological actions that appear to counter aging-associated diseases and conditions...

We describe three cases of hair loss in a female pattern hair loss (FPHL) distribution with histologic features of lichen planopilaris (LPP). All patients had a history of diffuse, gradual hair loss in a Christmas tree pattern that clinically presented as FPHL on gross and dermoscopic examination. Notably, there were no characteristic clinical signs of LPP and no histologic features of FPHL. These cases are most consistent with cicatricial pattern hair loss (CPHL). This relatively new entity is similar to fibrosing alopecia in a pattern distribution (FAPD) in that they are both scarring alopecias confined to a FPHL distribution, but CPHL lacks the clinical signs of perifollicular erythema and perifollicular keratosis seen in FAPD...

Mutations in the Pejvakin (PJVK) gene are thought to cause auditory neuropathy and hearing loss of cochlear origin by affecting noise-induced peroxisome proliferation in auditory hair cells and neurons. Here we demonstrate that loss of pejvakin in hair cells, but not in neurons, causes profound hearing loss and outer hair cell degeneration in mice. Pejvakin binds to and co-localizes with the rootlet component TRIOBP at the base of stereocilia in injectoporated hair cells, a pattern that is disrupted by deafness-associated PJVK mutations...

Male pattern baldness can have substantial psychosocial effects, and it has been phenotypically linked to adverse health outcomes such as prostate cancer and cardiovascular disease. We explored the genetic architecture of the trait using data from over 52,000 male participants of UK Biobank, aged 40-69 years. We identified over 250 independent genetic loci associated with severe hair loss (P<5x10-8). By splitting the cohort into a discovery sample of 40,000 and target sample of 12,000, we developed a prediction algorithm based entirely on common genetic variants that discriminated (AUC = 0...

Studies of developmental and functional biology largely rely on conditional expression of genes in a cell type-specific manner. Therefore, the importance of specificity and lack of inherent phenotypes for Cre-driver animals cannot be overemphasized. The Gfi1(Cre) mouse is commonly used for conditional hair cell-specific gene deletion/reporter gene activation in the inner ear. Here, using immunofluorescence and flow cytometry, we show that the Gfi1(Cre) mice produce a pattern of recombination that is not strictly limited to hair cells within the inner ear...

PREMISE OF THE STUDY: Plants of the family Loasaceae are characterized by a usually dense indument of various trichome types, including two basically different types of mineralized, unicellular trichomes (stinging hairs or setae and scabrid-glochidiate trichomes). Mineralized trichomes have long been known to have silicified or calcified walls, but recent studies demonstrated that trichomes of Loasaceae may also contain calcium phosphate. The current study investigates the distribution of different biominerals in the mineralized trichomes across several different taxa...

Clinical Question: Which interventions are effective and safe for treating female pattern hair loss (FPHL)? Bottom Line: There was low- to moderate-quality evidence that topical minoxidil (2% and 5%) was associated with improvements in FPHL. There was low-quality evidence that finasteride was no more effective than placebo. There were inconsistent results from studies that laser devices were effective, but total hair count increased compared with baseline (moderate- to low-quality evidence)...

J McCoy, A Goren, M Kovacevic, J Shapiro
Topical minoxidil is the only US FDA approved drug for the treatment of female pattern hair loss (FPHL). 5% minoxidil foam is only effective at re-growing hair in a minority of women (approximately 40%). Thus, the majority of FPHL patients remain untreated. Previously, we demonstrated that nonresponders to 5% minoxidil have low metabolism of minoxidil in hair follicles. As such, we hypothesized that increasing the dosage of topical minoxidil to low metabolizers would increase the number of responders without increasing the incidence of adverse events...

Bcl-2, the first gene shown to be involved in apoptosis, is a potent regulator of cell survival and known to have protective effects against a variety of age-related diseases. However, the possible relationship between hearing and Bcl-2 expression in the cochlea or auditory cortex of C57BL/6 mice, a mouse model of age-related hearing loss, is still unknown. Using RT-PCR, immunohistochemistry, and Western blot analysis, our results show that Bcl-2 is strongly expressed in the inner hair cells and spiral ganglion neurons of young mice...

Loss of function mutations in CTNNB1 have been reported in individuals with intellectual disability [MIM #615075] associated with peripheral spasticity, microcephaly and central hypotonia, suggesting a recognisable phenotype associated with haploinsufficiency for this gene. Trio based whole exome sequencing via the Deciphering Developmental Disorders (DDD) study has identified eleven further individuals with de novo loss of function mutations in CTNNB1. Here we report detailed phenotypic information on ten of these...

BACKGROUND: Alopecia areata (AA) is a common, chronic inflammatory disease characterized by nonscarring hair loss on the scalp or any hair-bearing area of the body. Recently, dermoscopy, a noninvasive diagnostic procedure, has been employed for the diagnosis of AA. AIM: To evaluate various dermoscopic patterns in AA and correlate these patterns with the disease activity and severity. MATERIALS AND METHODS: Dermoscopy was performed on AA patients using DL1 dermoscope (magnification ×10 was used)...

ABHD12 mutations have been linked to neurodegenerative PHARC (polyneuropathy, hearing loss, ataxia, retinitis pigmentosa, and early-onset cataract), a rare, progressive, autosomal, recessive disease. Although ABHD12 is suspected to play a role in the lysophosphatidylserine and/or endocannabinoid pathways, its precise functional role(s) leading to PHARC disease had not previously been characterized. Cell and zebrafish models were designed to demonstrate the causal link between an identified new missense mutation p...

PURPOSE: Health Related Quality of life (HRQoL) is increasingly recognised as an important indicator of outcome and well-being in oncology care. We set out in this study to evaluate whether significant association exists between anxiety disorders (ADs) and HRQoL in breast cancer, such that any intervention addressing ADs would potentially improve HRQoL. METHODS: A cross sectional evaluation of 200 attendees of an oncology clinic was done using designed questionnaire to gather socio-demographic and clinical data...

Parasites, by definition, extract energy from their hosts and thus affect trophic and food web dynamics even when the parasite may have limited effects on host population size. We studied the energetic costs of mange (Sarcoptes scabiei) in wolves (Canis lupus) using thermal cameras to estimate heat losses associated with compromised insulation during the winter. We combined the field data of known, naturally infected wolves with a data set on captive wolves with shaved patches of fur as a positive control to simulate mange-induced hair loss...

Objective: Hair loss is a significant problem worldwide. The most common cause of hair loss in men is male androgenetic alopecia, male pattern baldness, which is primarily due to the presence of nonfunctional or dead hair follicles in the scalp. Hair follicular unit transplantation has been a widely used technique to transplant hair follicles into bald areas. Although follicular unit transplantation generally gives satisfactory hair transplantation, efforts have been made to further increase the efficacy of follicular unit transplantation in hair regeneration...

Sketch portrait generation benefits a wide range of applications such as digital entertainment and law enforcement. Although plenty of efforts have been dedicated to this task, several issues still remain unsolved for generating vivid and detail-preserving personal sketch portraits. For example, quite a few artifacts may exist in synthesizing hairpins and glasses, and textural details may be lost in the regions of hair or mustache. Moreover, the generalization ability of current systems is somewhat limited since they usually require elaborately collecting a dictionary of examples or carefully tuning features/components...
