Trifarotene Alleviates Skin Photoaging Injury By Inhibition Of Jnk/C-Jun/Mmps, Xuan Fei, Lele Zixin Yang, Jingjing Zhang, Xiang Li, Mengtian Pan, Guangchen Xu, Cuixia Zhang, Fei Liu, Weirong Fang

Student Papers, Posters & Projects

Long-term exposure to ultraviolet (UV) radiation induces skin photoaging, which manifests as oxidative stress, inflammation, and collagen degradation. Multiple approaches (topical or systemic retinoids, antioxidants, alpha-hydroxy acids, laser, surgery) are used in the treatment of photoaged skin, and the use of topical retinoids is currently a primary clinical treatment. Previous studies revealed that retinoic acid promotes keratinocyte proliferation and reduces melanin deposition and matrix metalloproteinase (MMP) secretion; it also causes potential allergic and inflammatory damage to the skin. This study aimed to investigate the therapeutic effects and mechanisms of trifarotene, a functional retinoic acid analog, on UV-irradiated photoaging ICR and …

Minocycline-Induced Retinal Pigment Epithelium Hyperpigmentation Masquerading As Age-Related Macular Degeneration: Case Presentation And Proposed Mechanism, Michael D. Yu, Nikhil Bommakanti, Yoshihiro Yonekawa, Jose S. Pulido

Wills Eye Hospital Papers

PURPOSE: We describe the case of an 80-year-old man with bilateral minocycline-induced retinal pigment epithelium (RPE) hyperpigmentation, which initially masqueraded as AMD. Secondarily, using multimodal imaging features, we propose a mechanism for the development of minocycline-induced RPE hyperpigmentation.

OBSERVATIONS: The patient was referred with concern for AMD given the presence of macular drusenoid deposits on optical coherence tomography. However, funduscopic evaluation showed dense granular parafoveal hyperpigmentation, with a diffuse slate-colored hyperpigmentation throughout the peripheral fundus. Short-wavelength fundus autofluorescence of the macula disclosed no irregularities (as would be expected with drusen) while on near-infrared reflectance (NIR) imaging, numerous hyperreflective foci were …

Concurrent Varicella-Zoster Virus Reactivation And Recurrent Herpes Simplex Virus Infection In The C2 Dermatome With Varicella-Zoster Virus Encephalitis: A Case Report And Review Of The Literature., Morgan A Hatlovic, Madison Anzelc, Matthew Franklin

Ambulatory and Primary Care Articles

Herpes simplex virus (HSV) and varicella-zoster virus (VZV) are common viruses that are present in the general population. However, it is uncommon for both viruses to coincide at the same time and location. These viruses infect the nervous system to establish latency and have been associated with neurological disorders. We discuss a case of co-occurring VZV reactivation and recurrent HSV infection with subsequent VZV encephalitis following an insult to the neurologic system.

Herpes Vegetans In A Patient With Acquired Immunodeficiency Syndrome (Aids) In The Setting Of Immune Reconstitution Inflammatory Syndrome, Angelique Ruml, Ibeth Caceres, Anna Catinis, Theodore Rosen

Faculty, Staff and Students Publications

Herpes simplex virus (HSV) infections classically present as a vesicular eruption on an erythematous base; however, viral infections may present much differently in the setting of immune deficiency. Herpes vegetans is an atypical presentation of HSV that occurs in immunocompromised patients, typically those with human immunodeficiency virus infection and acquired immunodeficiency syndrome (AIDS). Herpes vegetans is characterized by hyperkeratotic, exophytic, and, sometimes, ulcerated nodules, often with a chronic and persistent course. Herein, we present an interesting example of biopsy-confirmed anogenital herpes vegetans in a 61-year-old male with AIDS in the setting of immune reconstitution inflammatory syndrome, an association that is …

Management Of Multiple Infantile Hemangiomas In A Preterm Infant: A Clinical Case Report, Erin Reese, Wyatt Grimm, Aaron Mcguffin

Marshall Journal of Medicine

Infantile hemangiomas (IH), the most prevalent infantile tumor, are benign vascular tumors arising from proliferation and dysregulation of angiogenesis. Hemangiomas are present after birth and undergo 3 stages: proliferation, plateau, and involution. IH are further categorized into superficial, deep, and mixed based on skin and internal organ involvement. IH are clinically diagnosed, and treatment options include active observation, corticosteroids, beta-blockers, pingyangmycin, vincristine, or laser treatment. Complications of untreated IH include ulceration, airway obstruction, and visual obstruction at sites of enlarging lesions. While most cases are benign, there are associated complications prompting a thorough investigation and proper management. Understanding a hemangioma …

Facial Skin Rejuvenation With Poly-L-Lactic Acid (Plla): Four Case Studies, Stanley Setiawan, Theressia Handayani, Stefani Luziani

Journal of General - Procedural Dermatology and Venereology Indonesia

Background: Facial aging is characterized by the decline and loss of skin structure. Poly-l-lactic acid (PLLA) is a biopolymer and biodegradable injection material that functions as a collagen stimulator. This active ingredient works by stimulating the formation of skin collagen after interacting with the PLLA crystal component. The expected final result is an increase in the skin volume with the thickening and increased density of the skin layers due to collagen remodeling. At present, data on the application of PLLA for facial photorejuvenation remains limited.

Case Illustration: Four patients aged 22-49 years old, with different severity of aging, underwent PLLA …
