Primary Cicatricial Alopecias (PCAs) are a group of skin diseases in which there is progressive and permanent destruction of hair follicles followed by replacement with fibrous tissue. Unfortunately, by the time patients seek clinical evaluation of their hair loss, the skin is already inflamed and/or scarred, so there is little hope for a return to their normal hair growth pattern. Clinical and basic science investigations are now focusing on three forms of human PCA, lichen planopilaris (LPP), frontal fibrosing alopecia (FFA), and central centrifugal cicatricial alopecia (CCCA)...

Baicalin is a traditional Chinese herbal medicine commonly used for hair loss, the precise molecular mechanism of which is unknown. In the present study, the mechanism of baicalin was investigated via the topical application of baicalin to reconstituted hair follicles on mice dorsa and evaluating the effect on canonical Wnt/β‑catenin signaling in the hair follicles and the activity of dermal papillar cells. The results indicate that baicalin stimulates the expression of Wnt3a, Wnt5a, frizzled 7 and disheveled 2 whilst inhibiting the Axin/casein kinase 1α/adenomatous polyposis coli/glycogen synthase kinase 3β degradation complex, leading to accumulation of β‑catenin and activation of Wnt/β‑catenin signaling...

Attempted murder by repeated poisoning is quite rare. The authors describe the case of a 62-year-old man who was admitted to an intensive care unit (ICU) for neurological disturbances complicated by inhalation pneumopathy. He presented a loss of consciousness while his wife was visiting him at the ICU (H0). Forty-eight hours later (H48), police officers apprehended the patient's wife pouring a liquid into his fruit salad at the hospital. Toxicological analyses of a blood sample and the infusion equipment (H0), as well as the fruit salad and its container (H48), confirmed the attempted poisoning with cyamemazine (H0) and hydrochloric acid (H48)...

Sonia is a 4 1/12-year-old girl with Waardenburg syndrome and bilateral sensorineural hearing loss who had bilateral cochlear implants at 2 7/12 years of age. She is referred to Developmental-Behavioral Pediatrics by her speech/language pathologist because of concerns that her language skills are not progressing as expected after the cochlear implant. At the time of the implant, she communicated using approximately 20 signs and 1 spoken word (mama). At the time of the evaluation (18 months after the implant) she had approximately 70 spoken words (English and Spanish) and innumerable signs that she used to communicate...

Quinine is an antimalarial drug that is toxic to the auditory system by commonly inducing hearing loss and tinnitus, presumably due to its ototoxic effects on disruption of cochlear hair cells and blockade of ion channels of neurons in the auditory system. To a lesser extent, quinine also causes ataxia, tremor, and dystonic reactions. As dopaminergic neurons are implicated to play a role in all of these diseases, we tested the toxicity of quinine on induced dopaminergic (iDA) neurons derived from human pluripotent stem cells (iPSCs) and primary dopaminergic (DA) neurons of substantia nigra from mice brain slices...

In the absence of an approved treatment by the US Food and Drug Administration, choosing one of the many off-label treatments available for a child, teen, or adult with alopecia areata (AA) can be challenging. The physician or midlevel provider treating a patient with AA needs to take into consideration the age of the patient, location of hair loss, disease extent and activity, and any ongoing medical or psychological issues. Many patients and their families have now also heard the "buzz" about evolving research, particularly with JAK inhibitors, for the treatment of AA...

Although genetic factors contribute to almost half of all cases of deafness, treatment options for genetic deafness are limited. We developed a genome-editing approach to target a dominantly inherited form of genetic deafness. Here we show that cationic lipid-mediated in vivo delivery of Cas9-guide RNA complexes can ameliorate hearing loss in a mouse model of human genetic deafness. We designed and validated, both in vitro and in primary fibroblasts, genome editing agents that preferentially disrupt the dominant deafness-associated allele in the Tmc1 (transmembrane channel-like gene family 1) Beethoven (Bth) mouse model, even though the mutant Tmc1Bth allele differs from the wild-type allele at only a single base pair...

BACKGROUND: Like a number of other countries, Australia mandates that a man who has had sex with men is deferred from donation until 12 months has elapsed since the sexual activity. This review examined whether this deferral period is justified by current evidence. STUDY DESIGN AND METHODS: Databases (Medline, EMBASE, Scopus) were searched using terms "blood donation" and "gay" or "MSM" and "HIV risk" from the mid-1980s to the present to investigate the history of donor deferral policy and its rationale in Australia...

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...

Omalizumab (anti-IgE) is used as add-on therapy for antihistamine refractory chronic urticaria patients. The most commonly reported adverse effects were headache, arthralgia, upper respiratory infections, fatigue, nausea and injection-site reactions. However, lately a few cases of hair loss have been reported. We describe a case of transient hair loss in a young female patient after initiating treatment with omalizumab. Despite this side effect, the patient continued with omalizumab treatment for 10 months with good effect...

Alopecia areata (AA) is a common, inflammatory, nonscarring type of hair loss. Significant variations in the clinical presentation of AA have been observed, ranging from small, well-circumscribed patches of hair loss to a complete absence of body and scalp hair. Patients affected by AA encompass all age groups, sexes, and ethnicities, and may experience frustration with the unpredictable nature of their disease for which there is currently no definitive treatment. The cause of AA remains incompletely understood, though it is believed to result-at least in part-from a loss of immune privilege in the hair follicle, autoimmune-mediated hair follicle destruction, and the upregulation of inflammatory pathways...
