Fiberglass dermatitis is a common form of occupational irritant contact dermatitis. Individuals experience a negative reaction to fiberglass fragments because of mechanical irritation. This review comprehensively analyzes the information in the existing literature on fiberglass dermatitis. Recognizing the different environmental risks factors for acquiring fiberglass dermatitis is necessary for better diagnosis and prevention. In addition to the identification of high‐risk populations exposed to fiberglass particles, the common clinical presentation and preventive measures that can reduce the risk of acquiring fiberglass dermatitis are thoroughly discussed.

Abstract: Background: Mexican mestizo population has a pluriethnic mixture of Amerindian, European and African ancestry, predominant in most Latin American countries. Until now, there are no reports about hair characteristics in this population, necessary to define normal values, for hair diseases evaluation and comparison among other ethnic groups. Methods: The VivoSight® swept‐source multibeam optical coherence tomography system was used to evaluate hair diameter and shape in 30 females. Three hair samples from each volunteer were measured transversely along three distances, generating nine cross‐sectional images, two measurements per image and 18 measurements per patient for a total of 540 diameter measurements. Results: Minimum hair diameter (n = 540) was 0.06 mm while maximum was 0.14 mm. Mean diameter was 0.10 ± 0.01 mm as compared with Asian hair, which ranges from 0.08 mm to 0.12 mm. On morphological analysis, Mexican Mestizo hair tends to have a round shape with homogenous diameters, resembling Caucasian and Asian hair. Conclusion: Mexican hair is similar to Asian hair in diameter and shape and can be classified as ‘thick’ hair, which make it more resistant and with more volume. Cosmetic products intended to improve hair care in this population must to consider this characteristic. [ABSTRACT FROM AUTHOR]

Abstract: Acne vulgaris is a chronic disease of the pilosebaceous units presenting as inflammatory or noninflammatory lesions in individuals of all ages. The current standard of treatment includes topical formulations in the forms of washes, gels, lotions, and creams such as antibiotics, antibacterial agents, retinoids, and comedolytics. Additionally, systemic treatments are available for more severe or resistant forms of acne. Nevertheless, these treatments have shown to induce a wide array of adverse effects, including dryness, peeling, erythema, and even fetal defects and embolic events. Zinc is a promising alternative to other acne treatments owing to its low cost, efficacy, and lack of systemic side effects. In this literature review, we evaluate the effectiveness and side‐effect profiles of various formulations of zinc used to treat acne. [ABSTRACT FROM AUTHOR]

Safe and effective treatment options for acne vulgaris are needed to address side effects and increasing rates of antibiotic resistance from current treatments. Nicotinamide is a vitamin with potent anti-inflammatory properties that could offer a potential treatment option. We aim to summarize the relevant literature on the role of nicotinamide in acne vulgaris and discuss the next steps necessary to move this approach into clinical practice. We searched PubMed for clinical studies using nicotinamide for treatment of acne vulgaris. We summarized the 10 studies that met our search criteria. Six of eight studies using topical nicotinamide led to a significant reduction in acne compared with the patient's baseline or performed similarly to another standard-of-care acne treatment. Both studies using an oral supplement containing nicotinamide resulted in a significant reduction in acne compared with baseline. No major adverse side effects were noted. Our review suggests that topical and oral nicotinamide has an unclear effect on acne vulgaris due to the limited nature of the available literature. Additional studies are needed comparing nicotinamide to other first-line acne treatments and evaluating the efficacy and side effect profile of nicotinamide over an extended period of time.

The article presents a case study of 45-year-old Uber driver with severe contact dermatitis of the face and prominent eyelid involvement. It mentions that the driver underwent patch tests which were positive for Myroxylon pereirae and fragrance exposure. It discusses the airborne contact dermatitis (ABCD) that are caused by Fragrance allergens.

Disseminated congenital pyogenic granuloma (DCPG) is an uncommon condition. Individual lesions of DCPG share clinical and histologic similarities with infantile hemangioma (IH); endothelial glucose transporter 1 (GLUT‐1), which is highly expressed in IH but generally not in pyogenic granulomas (PG), is an important diagnostic tool. Treatment for DCPG remains difficult. We describe a case of DCPG effectively treated with propranolol. [ABSTRACT FROM AUTHOR]

The article presents a case study of a 66-year-old man, who was admitted for patch testing due to the development of an itchy rash affecting his upper back and posterior upper arms. He underwent clinical examination which indicated many pink to skin-coloured papules coalescing into plaques. The patient was suspected to have fibreglass dermatitis, which is mostly observed in fishermen and surfers who sit in old boats or ride a surfboard without a wetsuit.

Morbihan disease, also referred to as solid facial edema, or rosacea lymphedema, is a rare disorder that involves chronic erythema and solid edema of the cheeks, eyelids, forehead and glabella and may arise as a complication of acne vulgaris or rosacea. Of note, it may be the only initial presenting symptom of these associated diseases. Few cases have been described in the literature, as its first description by Robert Degos in 1957. The condition is characterized by its chronicity, a typical clinical appearance and the lack of specific histopathologic or laboratory findings. The condition may wax and wane but typically does not resolve without treatment. Many cases of this condition tend to be recalcitrant to therapy, with topical and oral antibiotics regimens commonly used for rosacea generally being ineffective. The disease may easily go undiagnosed, as it mimics other more common skin conditions. We present a case of originally undiagnosed Morbihan disease mistaken for an atypical allergic rash, resistant to treatment, and complicated by dermatosis neglecta. [ABSTRACT FROM AUTHOR]
