We report a case of rash in a 35-year-old female presenting with erythematous papules and infiltrative plaques on the nose and upper jaw resembling rosacea. The patient had been experiencing these symptoms for one year. A pathological biopsy revealed an inflammatory infiltrate consisting of dense perivascular lymphocytes surrounding hair follicles and sweat glands in the dermis. Immunohistochemistry demonstrated a predominance of CD4+ T cells compared to CD8+ T cells. Based on the clinical manifestations, histopathology, and immunohistochemistry, the patient was diagnosed with Jessner's Lymphocytic infiltration of the skin (JLIS)...

BACKGROUND: Existing research links oxidative stress and inflammation to hair loss. Salvianolic acid B (SAB) is known for its anti-oxidative, anti-inflammatory, and other beneficial pharmacological properties. OBJECTIVE: To assess the efficacy of SAB in modulating hair growth. METHODS: In vivo experiments were conducted using C57BL/6 mice to evaluate the effects of SAB on hair and skin parameters. The study involved ex vivo analysis of human hair follicles (HFs) for hair shaft length and hair growth cycle assessment...

INTRODUCTION: Lichen planopilaris (LPP) and discoid lupus erythematosus (DLE) are primary scarring alopecias that pose diagnostic challenges clinically, where trichoscopy features may provide benefit in delineating these two cicatricial alopecia, and also helps in assessing the evolution and therapeutic response. To date, there are few reviews on dermoscopic findings in differentiating these two alopecias. METHODS: A systematic literature review was conducted using the PubMed and Google Scholar databases...

BACKGROUND: Alopecia areata is a chronic and relapsing condition that affects individuals of all age groups. Dermoscopy is a popular and non-invasive method for diagnosing alopecia areata. This study aimed to analyze dermoscopic findings and their relationship with age, gender, appearance, and clinical signs in children and adults. METHODS: This retrospective cross-sectional study was conducted on 124 children and adults diagnosed with alopecia areata who were referred to a Hospital in Iran between 2021 and 2022...

RESEARCH BACKGROUND: Ageing is a biochemical, metabolic and genetic physiological phenomenon. The suppression of melanin biosynthesis, evident in the greying of the hair, is a hallmark of ageing resulting from translation failure, reduced enzyme activity and cellular senescence. Putrescine, the smallest member of the polyamine family and an organic chemical, is present in living mammalian cells and plays a crucial role in regulating skin melanogenesis. Therefore, the purpose of this study is to explore the effect of putrescine on the signalling pathways of melanogenesis in melanoma cells...

Ticks are well-known vectors for transmitting disease and cause a variety of cutaneous manifestations to their afflicted host. Tick bite alopecia serves as a lesser-known illustration of this phenomenon, as few cases are documented in the literature. Scarring and nonscarring forms of tick-induced alopecia are described, with the latter being more common. This case highlights an adult female patient who developed a localized oval zone of midparietal scalp hair loss two months after the detection and removal of several ticks on her scalp...

INTRODUCTION AND IMPORTANCE: Supernumerary ribs are very rare. They may occur at any level of the spine. We present here a case of an unusual localization of an extra rib that has not been previously described in the literature. CASE PRESENTATION: A 4-year-old girl, with no medical history, presented with a congenital deformity in the sternal region mimicking a tail. The tail-like structure had a bony axis and was covered by normal skin and hairs. A computed tomography of the chest demonstrated that this structure was an abnormal bone articulated with the the sternum...

PURPOSE: Alopecia areata (AA) is an autoimmune disease characterized by hair loss that has significant psychosocial implications. This study aims to describe the patient-reported burden of severe AA, coping mechanism and information needs using data from the multinational AA Patient Satisfaction and Unmet Need Survey. PATIENTS AND METHODS: Participants with current or previous ≥50% scalp hair loss (n = 747) were recruited from 11 countries and completed a web-based survey that assessed demographics, clinical characteristics, disease burden and psychosocial impact...

Hair defined as curly has an elliptical cross sectional area and unique 3D form. While the chemical, morphological and mechanical characteristics of such hair are being explored using a range of analytical techniques, hair assembly (head of hair) characteristics and individual behaviour are difficult to determine via tress-based instrumental and sensory testing. Since the demand for more efficacious and personalized products is expected to gain pace, this project sets the groundwork for developing a taxonomy for exploring and classifying curly hair needs from an individual's perspective...

BACKGROUND: The relationship between skin diseases and psychiatric illnesses is bi-directional and is manifested as cause and effect. Psychiatric disorders such as stress, anxiety, and depression are seen to be instrumental in the development and progression of dermatological diseases on one hand, while on the other hand, cosmetic disfigurement caused by dermatological diseases is responsible for psychological distress in patients. The present study was conducted to investigate the spectrum of dermatological disorders in psychiatric patients to offer them holistic treatment and provide them with a better quality of life...

BACKGROUND Cosmetics are applied topically to enhance appearance and are commonly used by women of all ages. Cosmetics contain many chemical agents, but the incidence of adverse reactions is low, possibly due to underreporting. This questionnaire-based study included 392 women to evaluate information on the types of cosmetics purchased between December 2018 and March 2019, their use by the women surveyed, and their associated adverse events. MATERIAL AND METHODS A cross-sectional study was conducted among 392 women in Abbottabad, Pakistan, using a pre-structured and validated questionnaire to evaluate information on the types of cosmetics, their use, and their associated adverse events...

OBJECTIVES: Malassezia species are common, clinically relevant, and lipid-dependent yeasts of humans. They are also the leading causes of the dandruff problem of humans, and the azoles are used primarily in their topical and systemic treatment. Resistance to azoles is an emerging problem among Malassezia sp., which indicates the need of new drug assessments that will be effective against dandruff and limit the use of azoles and other agents in treatment. Among them, the efficacy of various combinations of piroctone olamine and climbazole against Malassezia sp...

Cosmetic products are chemical substances or mixtures used on the skin, hair, nails, teeth, and the mucous membranes of the oral cavity, whose use is intended to clean, protect, correct body odor, perfume, keep in good condition, or change appearance. The analysis of cosmetic ingredients is often challenging because of their huge complexity and their adulteration. Among various analytical tools, mass spectrometry (MS) has been largely used for compound detection, ingredient screening, quality control, detection of product authenticity, and health risk evaluation...

Energy-based devices are used to improve features of appearance for aesthetic reasons while avoiding more invasive methods. Examples of treatment targets are the reduction of wrinkles, sagging, unwanted skin lesions, body hair and excess fatty tissue, and the enhancement of muscle tissue. One treatment modality is the use of electromagnetic fields (EMF, 0‒300 GHz). The present work aims to give an up-to-date survey of cosmetic applications of EMF for professional use with an assessment of client and worker exposure and possible adverse effects...

INTRODUCTION: Lichen planopilaris (LPP) is one of the most common causes of scarring hair loss caused by immune-mediated inflammation resulting in atrophy and scaling. The key to preventing this irreversible hair loss is diagnosing and starting treatment at the earliest possible stage. As there is no definite cure for LPP, the therapy could be challenging. In the study, we conducted a single-blinded randomized clinical trial to evaluate the therapeutic effects, safety, and tolerability of platelet-rich plasma versus topical clobetasol in the treatment of LPP...

Previous studies have shown that cosmetic procedures and products that perpetuate Western hegemonic beauty standards among women have become increasingly popular, and pressures from sociocultural agents to utilize them are significant. However, little work has documented the relationship between perceived sociocultural pressures and use of cosmetic procedures and products among a larger age range of adult women. A community sample of 308 women aged 18-66, mean (SD) age of 35.7 (9.7), reported on the cosmetic procedures they had considered or used, as well as perceived pressures from the media, peers, romantic partners, and health and beauty professionals...

Traditional cosmetics play a significant role in the cultural practices and personal hygiene of many ethnic groups worldwide. The Oromo, an indigenous community in Ethiopia, has a rich history of utilizing local plants for cosmetic purposes. However, the use of plants as traditional cosmetics has only been poorly investigated as more emphasis was given to traditional medicines. The study thus aimed to identify and document plant species, and parts used in traditional cosmetics and associated knowledge, and practices among Oromo women in the Madda Walabu district, Southeastern Ethiopia...

BACKGROUND: The utilization of low-dose oral minoxidil (LDOM) has emerged as a relatively new treatment option for hair loss, gaining recognition among dermatologists worldwide. OBJECTIVE: To assess the knowledge, attitude, and practice patterns among dermatologists in Saudi Arabia regarding the use of LDOM in the management of hair loss. METHODS: An online survey, which was distributed to dermatologists practicing in Saudi Arabia through email and mobile messages...

BACKGROUND: There is a strong correlation between alopecia areata (AA) and the development of white hair. The AA presents itself in many clinical manifestations of depigmented hair as the condition advances. It is uncommon for unpigmented hair to extensively regrow for more than one hair growth cycle in AA and successful conversion to pigmented hair after treatment has not yet been reported. AIM: We report two case studies involving the persistent regrowth of white hair after AA that became pigmented through treatment...
