Demodex folliculorum (Trombidiformes: Demodecidae) infestation in medical students with facial dermatoses and healthy groups.

Demodex folliculorum (Simon, 1842) has been associated with various dermatological conditions. This study aimed to assess the prevalence of Demodex infestation in medical students with facial dermatoses compared with healthy medical students serving as controls. A total of 250 participants were enrolled, including 150 individuals with facial dermatoses and 100 healthy controls.

Effective treatment of corticosteroid-induced facial erythema using fractional radiofrequency microneedling.

Objectives: To investigate the efficacy of Fractional Radiofrequency Microneedling (FRM) in treating corticosteroid-induced facial erythema.

Methods: A retrospective study was conducted involving eight patients diagnosed as corticosteroid-induced facial erythema. Each patient underwent a single session of FRM.

Misdiagnosis of cutaneous facial sporotrichosis: An analysis of five cases.

Background: Facial cutaneous sporotrichosis presents with diverse clinical manifestations, often leading to misdiagnosis.

Objective: This study aims to present the clinical characteristics of five misdiagnosed cases of facial cutaneous sporotrichosis, aiming to enhance understanding of this disease and prevent misdiagnosis and mistreatment.

Methods: Clinical data, histopathology, and fungal culture results of these five cases were comprehensively analyzed.

Sebaceous gland atrophy due to seborrheic dermatitis in a patient with alopecia: A potential pitfall.

Seborrheic dermatitis is an inflammatory condition that usually presents with erythema, scaly greasy papules, and plaques affecting sebaceous gland-rich areas and predominantly involving the face and scalp. The diagnosis of seborrheic dermatitis can often be rendered based on the clinical presentation. However, in certain cases, a biopsy can be useful to distinguish it from clinical mimics such as psoriasis, discoid lupus, and rosacea.

Idiopathic aseptic facial granuloma: A retrospective study of 43 cases.

Background: Idiopathic aseptic facial granuloma (IAFG) is an underrecognized pediatric skin disease, currently considered within the spectrum of rosacea. It usually manifests as a solitary, reddish, asymptomatic nodule on the cheek that resolves spontaneously.

Methods: Retrospective and descriptive observational study of 43 pediatric patients with a clinical diagnosis of IAFG, followed between 2004 and 2022, at two general hospitals in Argentina.

FGD1-related Aarskog-Scott syndrome: Identification of four novel variations and a literature review of clinical and molecular aspects.

Patients with Aarskog-Scott syndrome (AAS) have short stature, facial anomalies, skeletal deformities, and genitourinary malformations. FYVE, RhoGEF, and PH domain-containing 1 (FGD1) is the only known causative gene of AAS. However, the diagnosis of AAS remains difficult, and specific treatments are still absent.

Sequential therapy with topical clobetasol for 14 days followed by hydroquinone versus hydroquinone alone in facial melasma treatment: a randomized, double-blind, controlled clinical trial.

Background: Clobetasol has demonstrated remarkable results in treating melasma within a short time frame; however, its use is limited because of the risk of local side effects. To date, there is no controlled trial on sequential clobetasol/hydroquinone for melasma. This study aimed to investigate the tolerability and efficacy of 0.

Residual facial erythema in atopic dermatitis patients treated with dupilumab stratified by machine learning.

Background: Persistent facial erythema represents a significant complication in atopic dermatitis (AD) patients undergoing treatment with dupilumab. Stratifying patients based on the erythema course is crucial for elucidating heterogeneous phenotypes and facilitating advanced drug efficacy predictions.

Objectives: This study aimed to identify factors associated with facial erythema severity in dupilumab-treated AD patients and to establish a prediction model for drug response based on the identified factors.

Efficacy of Black Gold, Delicate Pulse Light, Super Photon Skin Rejuvenation for Pigmented Dermatoses.

Context: Pigmented dermatoses are skin diseases characterized by pigmentation changes in the skin's surface due to abnormal melanocyte production. Photon-skin-rejuvenation technology can be effective for the management of facial pigmented dermatoses. Black Gold Delicate Pulse Light (DPL) Super Photon Skin Rejuvenation therapy is a new technology based on traditional photo rejuvenation.
