Dermatophytoses are fungal infections of the skin, hair, and nails that affect approximately 25% of the global population. Occlusive clothing, living in a hot humid environment, poor hygiene, proximity to animals, and crowded living conditions are important risk factors. Dermatophyte infections are named for the anatomic area they infect, and include tinea corporis, cruris, capitis, barbae, faciei, pedis, and manuum. Tinea incognito describes steroid-modified tinea. In some patients, especially those who are immunosuppressed or who have a history of corticosteroid use, dermatophyte infections may spread to involve extensive skin areas, and, in rare cases, may extend to the dermis and hair follicle. Over the past decade, dermatophytoses cases not responding to standard of care therapy have been increasingly reported. These cases are especially prevalent in the Indian subcontinent, and Trichophyton indotineae has been identified as the causative species, generating concern regarding resistance to available antifungal therapies. Antifungal-resistant dermatophyte infections have been recently recognized in the United States. Antifungal resistance is now a global health concern. When feasible, mycological confirmation before starting treatment is considered best practice. To curb antifungal-resistant infections, it is necessary for physicians to maintain a high index of suspicion for resistant dermatophyte infections coupled with antifungal stewardship efforts. Furthermore, by forging partnerships with federal agencies, state and local public health agencies, professional societies, and academic institutions, dermatologists can lead efforts to prevent the spread of antifungal-resistant dermatophytes.

Baricitinib (Olumiant®), a Janus kinase (JAK) inhibitor, is the first drug approved for the treatment of severe alopecia areata in the USA and the EU. Severe alopecia areata is usually difficult to treat and relapse is common. Patients with this disorder are more likely to suffer from anxiety and depression. In two pivotal placebo-controlled phase 3 clinical trials in adults with severe alopecia areata, oral baricitinib once daily was associated with clinically meaningful scalp, eyebrow, and eyelash hair regrowth over 36 weeks. Baricitinib was generally well tolerated with the most common adverse events being infections, headaches, acne, and elevated levels of creatine phosphokinase. While longer-term data will be necessary to more fully understand the benefits and risks of the drug, currently available data suggest that baricitinib is a useful treatment for patients with severe alopecia areata. Plain Language Summary: Alopecia areata is a disorder in which an autoimmune attack is mounted against hair follicles, resulting in hair loss ranging from patches of hair loss through to complete hair loss. Alopecia areata can recur throughout an individual's lifetime and can cause significant psychological distress, with patients more likely to experience anxiety or depressive disorders within their lifetime. Baricitinib (Olumiant®) is a drug that blocks the signaling of immune messengers to halt autoimmune attack and allow hair regrowth. In two clinical trials, adults with severe alopecia areata receiving baricitinib were more likely to recover from an episode of alopecia areata (achieve 80% or more scalp coverage) than those receiving placebo. Eyebrow and eyelash regrowth was also more common in patients receiving baricitinib than placebo. Baricitinib was generally well tolerated, with infections being the most common adverse events. While longer-term data will be of interest, baricitinib appears to be a useful treatment for patients with severe alopecia areata. [ABSTRACT FROM AUTHOR]

Purpose Hidradenitis suppurativa (HS) is a debilitating chronic inflammatory skin disease with an often-unsatisfactory response to treatment. The objective was to evaluate the association between HS and pregnancy, delivery and neonatal outcomes. Methods The United States’ Healthcare Cost and Utilization Project-Nationwide Inpatient Sample database was used to conduct a retrospective cohort study among all women who delivered between 1999 and 2015. ICD-9 code 705.83 identified those with HS, with the remaining deliveries composing the comparison group. Multivariate logistic regression compared maternal and neonatal outcomes between these two groups, while adjusting for baseline maternal variables. Results The study included 13,792,544 deliveries, of which 1021 were associated with an HS diagnosis (7.4/100,000 deliveries). During the observation period, there was an upward trend in the prevalence of HS among pregnant women (<0.0001). Pregnant women with HS were more likely to be African-American, to belong to a lower income quartile, and to be insured by Medicaid. They were also more likely to smoke, to be morbidly obese, and to be hypertensive. Compared with women without HS, those with HS had a greater likelihood of developing preeclampsia (OR 1.36, 95% CI 1.08–1.71), delivering by cesarean section (OR 1.78, 95% CI 1.56–2.02), and having a baby with congenital anomalies (OR 2.00, 95% CI 1.10–3.62). Conclusions Although HS is a complex skin disorder, pregnancies complicated by HS had comparable outcomes to non-HS pregnancies, with the exception of a greater risk of preeclampsia, cesarean sections, and congenital anomalies. Health-care providers and women should be aware of these HS associated risks. [ABSTRACT FROM AUTHOR]

Background: Hedgehog signaling is essential to the regulation of embryonic development, tissue homeostasis, and stem cell self-renewal, making it a prime target for developing cancer therapeutics. Given the close link between aberrant Hedgehog signaling and cancers, many small molecular compounds have been developed to inhibit Smoothened, a key signal transducer of this pathway, for treating cancer and several such compounds have been approved by the United States Food and Drug Administration (GDC-0449 and LDE-225). However, acquired drug resistance has emerged as an important obstacle to the effective use of these first generation Hedgehog pathway blockers. Thus, new Smoothened inhibitors that can overcome such resistance is an urgent need going forward. Results: We established the Smoothened/βarrestin2-GFP high-throughput screening platform based on the mechanistic discovery of Hedgehog signaling pathway, and discovered several active small molecules targeting Smoothened including 0025A. Here we show that 0025A can block the translocation of βarrestin2-GFP to Smoothened, displace Bodipy-cyclopamine binding to wild-type Smoothened or mutant Smoothened-D473H, reduce the accumulation of Smo on primary cilia and the expression of Gli upon Hedgehog stimulation. In addition, we show that 0025A can effectively suppress hair follicle morphogenesis and hair growth in mice. Conclusions: Our results demonstrate that 0025A is a potent antagonist targeting Smoothened wild-type and mutant receptors in the Hedgehog signaling pathway and may provide a new therapy for refractory cancers.

Maximizing the impact of HIV pre-exposure prophylaxis (PrEP) requires optimizing access and adherence for those at risk of contracting HIV. This study examined challenges to the processes of accessing and adhering to PrEP encountered by participants from a large, U.S. urban clinical center and assessed the utility of objectively monitoring PrEP adherence via urine. Most participants (65%) reported starting PrEP within 1–3 months of hearing about it, although 35% of participants encountered a provider unwilling to prescribe PrEP. Self-reported adherence was high among this population, with remembering to take the medication reported as the major barrier to adherence (44%) rather than cost or stigma. Urine tenofovir (TFV) monitoring was highly acceptable to this population, and participants indicated greater willingness to undergo urine monitoring every 3 months compared to finger prick (dried blood spot), phlebotomy, or hair follicle testing. These findings highlight the importance of focusing efforts toward reducing obstacles to PrEP use and support the use of urine TFV adherence monitoring as a marker of PrEP adherence.

Hair loss or alopecia is a common dermatological condition affecting up to 2% of the world population. It is often caused by hereditary factors, such as male or female pattern baldness, but it can also result from various environmental factors, an unbalanced diet, or chronic illness. While hair loss is not life-threatening, it can cause significant anxiety, depression, and other psychological problems, ultimately impacting an individual's quality of life. Various treatments for hair loss, including both synthetic drugs, such as minoxidil and finasteride, or medicinal herbs, have been approved by the Food and Drug Administration. Despite synthetic drugs' effectiveness, they may come with potential side effects. Natural remedies have been proposed as a viable option for treating hair loss because many chronic disorders can cause alopecia. As such, this review focuses on identifying alternative, efficient treatment agents with limited side effects. Specifically, it looks into medicinal plants as potential healing agents for treating hair loss. To gather relevant information for the study, multiple databases were searched, including Scopus, PubMed, and Google Scholar. A comprehensive search was conducted using a range of search terms, such as "hair loss", "alopecia", "natural remedies for hair loss", "herbal treatments for hair loss", and others to extract relevant scientific articles. Many medicinal plants and natural compounds have shown potential in reducing hair loss, thanks to their anti-inflammatory and antioxidant properties and the ability to improve local metabolism when applied externally. According to existing literature, herbal extracts and formulations derived from plants, such as Urtica dioica, Humulus lupulus, Serenoa repens, Vitis vinifera, Pygeum africanum, Cucurbita pepo, etc. , as well as certain individual herbal compounds, micronutrients, bee products, and keratin, may be effective in reducing hair loss directly or indirectly. Research suggests that medicinal plants and a variety of natural compounds hold promise in promoting hair growth and preventing alopecia., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Over the last 20 years, the global North has witnessed the growing prominence of immigrant rights movements. This article examines how this highly stigmatized population has achieved a certain degree of legitimacy in hostile political environments. The central claim of the article is that this kind of legitimacy is initially achieved through the efforts of activists to represent undocumented immigrants in ways that resonate with the normative values of the nation. The author examines how activist networks are formed to present their cases within national political fields and the effects of this process on the political identities of immigrants and their respective citizenship regimes. The process of gaining legitimacy is contradictory. It contributes to nationalizing the political identities of foreigners and reproducing the exclusionary logic of national citizenship regimes. But in doing this, it encourages those who cannot conform to national values to embrace more radical and universal conceptions of rights. The generation of competing discourses and notions of rights (national versus universal) therefore arises through struggles to make undocumented immigrants into legitimate political subjects.

Tinea capitis is a fungal infection of the hair follicles of the scalp. In the US, the most common organisms have traditionally been Trichophyton tonsurans, and occasionally Microsporum canis. This study was designed to examine patterns of organisms causing tinea capitis and determine factors associated with infection. A retrospective database analysis was conducted to locate records of patients with tinea capitis from May 2001 to May 2006 at Nationwide Children’s Hospital in Columbus, OH. Descriptive statistics, frequency analysis, chi-squared test, and Student’s t-test were performed to evaluate types of causative organisms and associated patient characteristics. One hundred and eighty-nine charts of patients with a positive scalp culture for tinea capitis were located. Trichophyton tonsurans (88.9%) was the foremost causative agent followed by Trichophyton violaceum (4.2%). Tinea capitis was more prevalent among African Americans and was more common in urban areas ( P < 0.05). Children of African descent inhabiting urban settings were most vulnerable to tinea capitis. The most common organism isolated in this retrospective study was T. tonsurans. Trichophyton violaceum and Trichophyton soudanense were also isolated, which are not commonly reported causes of tinea capitis in the US. [ABSTRACT FROM AUTHOR]

Alopecia areata (AA) is a genetically determined, immune-mediated disorder of the hair follicle that affects 1%-2% of the U.S. population. It is defined by a spectrum of severity that ranges from patchy localized hair loss on the scalp to the complete absence of hair everywhere on the body. In an effort to define the genetic basis of AA, we performed a genomewide search for linkage in 20 families with AA consisting of 102 affected and 118 unaffected individuals from the United States and Israel. Our analysis revealed evidence of at least four susceptibility loci on chromosomes 6, 10, 16 and 18, by use of several different statistical approaches. Fine-mapping analysis with additional families yielded a maximum multipoint LOD score of 3.93 on chromosome 18, a two-point affected sib pair (ASP) LOD score of 3.11 on chromosome 16, several ASP LOD scores >2.00 on chromosome 6q, and a haplotype-based relative risk LOD of 2.00 on chromosome 6p (in the major histocompatibility complex locus). Our findings confirm previous studies of association of the human leukocyte antigen locus with human AA, as well as the C3H-HeJ mouse model for AA. Interestingly, the major loci on chromosomes 16 and 18 coincide with loci for psoriasis reported elsewhere. These results suggest that these regions may harbor gene(s) involved in a number of different skin and hair disorders. [ABSTRACT FROM AUTHOR]

The article presents a study on the impact of the normal hair growth cycle to the wound healing in the U.S. The study reveals that wounds created during the anaphase stage of the hair follicle cycle shows the increased keratinocyte proliferation. The increased keratinocyte proliferation was able to contribute to the acceleration of wound re-epithelialization.

The article focuses on Beauty Brains, a web blog in the U.S which deals on important issues and details in the beauty business. It usually deals on matters related to cosmetics and hair care wherein a pair of cosmetic chemists are available to answer queries which includes the perils of blending hair care products down to the innocous mites which may stay in the hair follicles as well as the treatment for split ends. It stressed on the problem on split ends which includes a discussion of the hair structure and stated that it can not be avoided or cured even with the best shampoo available in the market for the real truth is that it is unfixable since hair is dead therefore it can not heal itself.

The Second International Research Workshop on Alopecia Areata will be held on November 7 and 8, 1994 in Bethesda, Maryland. The two-day workshop will bring together investigators for an open exchange of recent advances in alopecia areata, as well as studies of hair follicle biology. Topics will include immunogenetics, target tissues, dermal-epidermal instructions, stem cells, growth factors, and animal models. Results of this workshop will guide further research in this field. The workshop is co-sponsored by the National Alopecia Areata Foundation and the National Institute of Arthritis and Musculoskeletal and Skin Diseases.

A conference on "Molecular and Structural Biology of Hair Growth" will be held in Arlington, Virginia, during January 23-25, 1991. The major topics discussed will include the regulation of hair follicle structural protein expression, themes of the molecular structure of hair, laboratory models for studying hair growth, mesenchymal components of the follicle, hair follicle pigmentation, growth factors and cytokines affecting hair growth, hormonal influence on molecular processes of the follicle, and principles of hair follicle induction and cycle.
