patchy alopecia

BACKGROUND: Conflicting results have emerged in studies conducted to reveal the relationship between alopecia areata (AA) and depression and anxiety. The comorbidity of depression and anxiety in patients with patchy AA who applied to a tertiary care center will be investigated and compared with a healthy control group. METHODS: This study included 86 patients with AA and 85 healthy volunteers. The patients and controls completed Beck Depression Inventory (BDI) and Beck Anxiety Inventory (BDI)...

INTRODUCTION: Patchy alopecia is a common adverse effect of stereotactic radiosurgery (SRS) on the calvarium and/or scalp, yet no guidelines exist for its prevention. This study aims to investigate the incidence and outcomes of patchy alopecia following SRS for patients with calvarial or scalp lesions and establish preventive guidelines. METHODS: The study included 20 patients who underwent CyberKnife SRS for calvarial or scalp lesions, resulting in a total of 30 treated lesions...

Mycobacterium abscessus ( M. abscessus ) is a fast-growing, non-tuberculous mycobacterium (NTM) that can cause human infections varying from superficial infection to pulmonary or even systemic infections. The latter is more commonly appeared in immunocompromised patients. The skin infection caused by M. abscessus often appears after trauma or surgical procedure. It is often manifested by subcutaneous nodules, papules, erythema, tender erythematous or violaceous plaques, cellulitis, abscesses, ulcerations, and draining sinuses...

Alopecia areata is an autoimmune hair loss disease that is non-scarring and is characterized by chronic inflammation at the hair follicle level. Clinically, patients' presentation varies from patchy, circumscribed scalp involvement to total body and scalp hair loss. Current management is guided by the degree of scalp and body involvement, with topical and intralesional steroid injections as primarily first-line for mild cases and broad immunosuppressants as the mainstay for more severe cases. Until recently, the limited number of blinded, randomized, placebo-controlled clinical trials for this disease had made establishing an evidence-based treatment paradigm challenging...

The adverse psychosocial impact of androgenetic alopecia (AGA) is often framed as an essential motivation for developing efficacious treatments to halt hair loss or promote regrowth, especially since AGA is common among men but does not result in physically harmful or life-limiting consequences. Yet, empirical evidence documenting the impact of AGA on men's psychological wellbeing and quality of life is patchy and has not previously been subject to systematic review. This systemic review and meta-analyses aim to integrate and evaluate evidence regarding the psychosocial impact of AGA on men...

BACKGROUND: Although non-scarring alopecia (NSA) is a frequent clinical finding in patients with systemic lupus erythematosus (SLE), it has been poorly described in the literature. It is considered a nonspecific sign in the current classification of skin lesions of LE. The aim of this study was to give an updated overview of the spectrum of NSA in LE patients, with emphasis on the clinical significance thereof. METHOD: We conducted a review of the English literature using the PubMed-Medline database using the keywords "Alopecia" + "Lupus erythematosus"...

BACKGROUND/OBJECTIVES: As surgical techniques evolve, there remains underutilisation of secondary intention healing as a valid reconstruction option. This is largely due to concerns regarding inferiority of wound cosmesis, increased downtime with wound healing and infection risk (Dermatol Surg. 2020; 46(12): 1492-97). METHODS: We sought to look at the outcome of secondary intention healing in a cohort of patients seen at a private dermatology practice with small to medium sized scalp defects...

BACKGROUND/OBJECTIVES: Alopecia areata (AA) is a T-cell driven autoimmune disease, which results in hair loss. This study aims to determine the efficacy, tolerability and safety of different concentrations of anthralin in the treatment of pediatric AA. METHODS: A retrospective cohort study of patients < 18 yo diagnosed with AA treated with anthralin at SickKids Hospital, Toronto dermatology outpatient clinic in 2016 - 2018. Anthralin used at 0.1%, 0.2%, 0.5% and 1% in petrolatum at short contact, at increments of 15 minutes every week until a 1 hr maximum contact achieved...

CASE SUMMARY: A case of skin fragility in an 8-year-old domestic shorthair cat with pituitary-dependent hyperadrenocorticism is described. The cat was referred to the Feline Centre at Langford Small Animal Hospital with a 2-month history of multiple skin wounds with no known traumatic aetiology. A low-dose dexamethasone suppression test was performed before referral, which was consistent with hyperadrenocorticism. On presentation, the cat had multiple cutaneous lacerations and patchy areas of alopecia...

Beard alopecia areata, or alopecia areata barbae, (BAA) is a subset of alopecia areata, a T-cell mediated inflammatory disease that disrupts the hair follicle cycle leading to early onset of catagen. The aim of this review is to help strengthen clinicians' skills in the evaluation, diagnosis, and management of BAA. We performed a literature review according to the modified PRISMA guidelines, using a combination of relevant key words in electronic databases. According to the data from the 25 articles on BAA reviewed here, BAA mostly affects middle-aged men (mean age 31 years) who typically experience patchy hair loss in the neck region, which spreads to the scalp within 12 months...

A 46-year-old patient with extensive patchy alopecia areata (AA) treated successfully with platelet-rich plasma (PRP) is presented. The therapy was used in three applications at monthly intervals. The treatment results were analyzed with clinical photography, quantitative assessment of scalp hair, digital trichoscopy, and evaluation of the patient's quality of life. Results of studies conducted with PRP therapy in alopecia areata are briefly presented. PRP injections in alopecia areata are a relatively effective, safe, low-pain, and minimally invasive treatment method...

BACKGROUND: Very few reports have described trichoscopic patterns of allergic scalp contact dermatitis (ASCD), which is usually an exclusion diagnosis on hair disorders. Trichoscopy is a simple, diffused method for investigating scalp diseases and may help to establish the characteristic findings of ASCD. METHODS: A retrospective chart review was conducted on patients who visited the outpatient hair consultation at the Department of Experimental, Diagnostic, and Specialty Medicine of the University of Bologna, Italy, from January 2020 to September 2021...

BACKGROUND: Dermatologic signs and symptoms can be the manifestations of a single disease or different diseases, and it is proven that some are associated with one another. These connections are not fully understood, but the answer lies in the pathophysiology of each disease. CASE PRESENTATION: We report the case of a 6-year-old Middle-Eastern girl who presented with two skin lesions on the dorsum of her foot, along with scaling of her soles and palms, face skin discoloration, and areas of patchy alopecia on her scalp...

Tumid lupus erythematosus (TLE), a subtype of chronic cutaneous lupus erythematosus (CCLE), presents with firm erythematous plaques that lack surface changes such as follicular plugging or scale. These lesions most commonly occur on the face and other photosensitive areas but may also present on the scalp as recurrent circumscribed patches of non-cicatricial alopecia. Including TLE as part of the differential for non-cicatricial alopecia can prove helpful in patients who fail to improve with empiric first-line treatments for more common causes of hair loss...

Central centrifugal cicatricial alopecia (CCCA) is a lymphocytic scarring alopecia that predominantly affects women of African descent. Recent studies have demonstrated prevalence in children and adolescents, as well as Asian populations. A thorough search of Pubmed, Cochrane Database of Systematic Reviews, OVID Medline and Google Scholar was conducted using keywords such as "central centrifugal cicatricial alopecia", "scarring hair loss", "scarring alopecia", "hot comb alopecia", "pediatric" and "adolescent"...

BACKGROUND: Alopecia areata (AA) is an immune-mediated nonscarring hair loss disorder with multiple subtypes, including alopecia universalis (AU). Previous studies have shown a link between serum lipid profile and alopecia. We aimed to investigate the frequency of fatty liver in patients with AU and patchy alopecia areata (PAA) compared to a control group. METHODS: This case-control study included patients with AU and PAA referred to a dermatology clinic from September 23, 2019 to September 23, 2020...

Alopecia is a common feature in several autoimmune diseases. With a wide spectrum of clinical presentations, it may manifest with a scarring or non-scarring nature, in a diffuse, patchy, or localized pattern. We as dermatologists have the opportunity of assessing patients with hair loss who may have an underlying undiagnosed autoimmune disorder. This review aimed to describe the main clinical, trichoscopic, and histopathological features of hair disorders associated with autoimmune diseases.

Alopecia areata (AA) is an autoimmune condition characterized by patchy, nonscarring hair loss. Few studies of AA have adequately included participants from underrepresented groups when evaluating the burden of AA in the United States. We conducted a cross-sectional study of personal/demographic factors and AA using the ongoing All of Us (AoU) Research Program. AoU enrolls adults over 18 years either as direct volunteers or through participating Health Care Provider Organizations by prioritizing recruiting underrepresented groups...

BACKGROUND: Alopecia areata (AA) is characterized by limited non-scarring patchy alopecia, which appears as round or oval patches and is prone to recurrence, causing severe psychological burdens to patients. No specific device has been approved by the FDA for the treatment of baldness, but new treatments are being investigated and treatments such as the excimer laser, He- Ne laser, and excimer lamp have been proposed. A growing number of studies have found that fractional lasers also have great potential in the treatment of AA...
