Successful Treatment of Calcium Hydroxylapatite Nodules With Intralesional 5-Fluorouracil, Dexamethasone, and Triamcinolone.

Although infrequent, non-inflammatory nodules are potential complications associated with dermal filler injections. There is a lack of consensus in the literature regarding potential treatments to help resolve nodules associated with calcium hydroxylapatite (CaHA) filler injections. This case report describes the successful treatment of a non-inflammatory nodule related to CaHA injection using a combination of 5-fluorouracil, dexamethasone, and triamcinolone.

Exploring the potential of intradermal platelet-rich plasma in treating acquired bilateral nevus of Ota-like macule (Hori's nevus): A pilot study.

BACKGROUND: Hori's nevus is a common and challenging dermatological condition, often complicated by post-inflammatory hyperpigmentation following treatment. Platelet-rich plasma (PRP) has demonstrated efficacy in the treatment of hyperpigmentation disorders such as melasma and periorbital darkening. Given the benefits and minimally invasive nature of PRP treatments, exploring its application in managing Hori's nevus through further investigation is worthwhile. AIMS: To evaluate the safety and effectiveness of intradermal PRP therapy for the treatment of Hori's nevus. METHODS: Ten female patients received bilateral intradermal PRP injections every 2 weeks for a total of four treatments. The modified dermal pigmentation and severity index (mDPASI), mean melanin index (MI), brightening score, patient self-assessment, and clinical photographs were evaluated at 2, 4, 8, and 12 weeks post-treatment. Adverse events were also recorded to determine treatment safety. RESULTS: At 12 weeks post-treatment, mDPASI decreased 38.86%, from 0.929 ± 0.617 to 0.568 ± 0.415 (p < 0.05). The mean melanin index decreased 12.75%, from 208.650 ± 26.319 to 182.052 ± 17.028 (p < 0.05). In addition, the mean brightness score evaluated by two experts was 1.4, indicating 25-50% improvement. At the end of the study, 50% of the patients reported 50-75% improvement. Side effects included pain, mild edema, and bruising, which resolved spontaneously within 3 days. No serious side effects were found. CONCLUSION: Our results suggest that intradermal PRP therapy may be a safe and effective alternative for the treatment of Hori's nevus and can complement conventional interventions. However, further research with a larger sample size, control groups, and longer follow-up is needed to confirm these findings.

An Academic Dermatology Center's Structured Platelet-rich Plasma Approach to Patients with Androgenetic Alopecia.

Androgenetic alopecia (AGA) is a prevalent cause of hair loss with complex pathophysiologic mechanisms that pose challenges for effective treatment. Despite various therapeutic approaches yielding only partial results, regenerative treatments, such as platelet-rich plasma (PRP), have gained popularity. However, the lack of standardized PRP practices, encompassing product preparation and application, has been a significant concern. This article aims to contribute to fill this gap by presenting a comprehensive overview of PRP practices at a large academic center. Through detailing our protocols, this work not only contributes to the understanding of AGA treatment but also emphasizes the crucial aspect of treatment standardization in the context of PRP therapy. By providing a practical representation of our institutional PRP practices, we aim to contribute to the ongoing discourse on refining and implementing standardized protocols, fostering reproducibility, and improving clinical outcomes in the management of AGA.

Microplastics in dermatology: Potential effects on skin homeostasis.

BACKGROUND: Microplastics (MPs) and nanoplastics (NPs) have become a growing concern in dermatology due to their widespread presence in cosmetic formulations and the environment. These minuscule synthetic polymer particles prompt an essential exploration of their potential impact on dermatological homeostasis. AIMS: This study aims to investigate the effects of MPs and NPs on the integumentary system. Specifically, it seeks to understand the potential cutaneous alterations, inflammatory responses, and disruptions to the skin's physiological functions caused by these synthetic particles. PATIENTS/METHODS: The investigation involves a comprehensive analysis of emerging research on MPs and NPs. This includes their presence in cosmetic formulations and environmental pervasiveness. The study delves into their capacity to breach the cutaneous barrier, raising concerns about the implications of prolonged exposure. RESULTS: Evidence suggests that MPs and NPs may indeed incite cutaneous alterations, provoke inflammatory responses, and disturb the homeostasis of the skin's physiological functions. Their small dimensions enhance their capability to breach the cutaneous barrier, further emphasizing the apprehensions associated with prolonged exposure. CONCLUSIONS: While a precise understanding of the implications of MPs and NPs on dermatological health remains an ongoing scientific endeavor, this study underscores the growing significance of these synthetic particles. The findings emphasize the need for proactive measures to safeguard both individual well-being and environmental preservation in the context of dermatological health.

Fourth Branchial Cleft Cyst: An Important Differential Diagnosis in Lateral Neck Masses.

Branchial anomalies are a result of abnormal development during embryogenesis and are a rare cause of lateral neck masses of congenital origin. The second branchial cleft is the most common site of origin, with abnormalities arising from the first, third, and fourth clefts being rarer. Although cysts originating from branchial clefts are infrequent, it is important to consider this pathology in the differential diagnosis of neck masses, particularly those located laterally. This article discusses a rare case of a 49-year-old female patient who presented with the sudden appearance of a lateral neck mass after sports practice. The patient underwent extensive diagnostic studies, including radiological studies, which were compatible with a fourth branchial cleft cyst. The patient remains asymptomatic, and possible surgical treatment is being evaluated by the head and neck surgery service. This clinical case highlights the importance of prompt diagnosis and appropriate management of rare pathologies such as branchial cleft cysts.

Milia-like idiopathic calcinosis cutis of the forehead in an adult without Down's syndrome successfully treated with a CO2 laser.

BACKGROUND: Idiopathic calcinosis cutis is an uncommon form of calcinosis cutis. It may present as tumoral calcinosis, subepidermal calcified nodules or scrotal calcinosis. Subepidermal calcified nodules may also present as milia-like lesions commonly seen in children with Down's syndrome in the absence of tissue damage or metabolic disorders, it has been seldom reported in adults. The treatment of choice is surgical excision. However, a surgical approach may not always be beneficial to the patient given the cosmetic outcomes. Here, we describe the successful use of a CO2 laser in the treatment of milia-like calcinosis cutis of the forehead in an adult without Down's syndrome. AIMS: To describe the treatment of Milia-like idiopathic calcinosis cutis of the forehead in an adult without Down's syndrome successfully treated with a CO2 laser. METHODS: We report a case of a 48-year-old man who presented with skin-colored hard asymptomatic papules on the forehead that started about 9 years ago, a biopsy was performed and a diagnosis of milialike calcinosis cutis was made. Surgical excision was discarded regarding the location and the number of lesions, instead, a CO2 laser was used to treat this condition. RESULTS: Successful laser excision of the lesions with appealing cosmetic results. CONCLUSIONS: CO2 laser seems to be a valuable tool to treat milia-like calcinosis cutis lesions.

Perspectives in cosmetic dermatology: What is in front of the mirror?

Managing patient expectations can be a difficult task and is one that cosmetic dermatologists frequently encounter. Misinformation and unrealistic expectations can oftentimes exist regarding cosmetic procedures and their results. These misconceptions can result in patient dissatisfaction and frustration on the physician's behalf. This case report underscores the importance of utilizing what is arguably the most basic and ancient tool in the office, the mirror. There are many different facets to the patient encounter and a variety of devices at the physician's disposal. Proper use of this valuable tool can improve communication, elucidate patient concerns, and reflect the focus on the patient. These can ultimately lead to improved procedure outcome and patient satisfaction.
