A Review of Neuromodulators and Energy-Based Devices for Optimizing Nasal Appearance.

Importance: The demand for less invasive nasal procedures has been increasing, highlighting a gap in research on alternatives beyond fillers. This review explores the potential of neuromodulators and energy-based devices for nonsurgical rhinoplasty. Observations: Both botulinum toxin and energy-based devices used independently or alongside fillers have been studied for nasal shape adjustments. Neuromodulator injection of the depressor septi nasi can reduce nasal tip droop, which can reduce the appearance of a plunged nose. Treatment of the dilator naris can minimize alar flaring, giving the appearance of a thinner nasal tip. These methods primarily reported patient-reported outcomes. Energy-based devices have been used to address nasal skin quality and shape contouring, including resurfacing devices for rhinophyma with improvement in both physician and patient-reported outcomes. The 1470 nm laser achieved nasal reshaping after two sessions. Radiofrequency microneedling was notable for volumetric reduction in the nose (excluding nasal tip), confirmed by 3D imaging, lasting about 12 months. Conclusions and Relevance: The use of neuromodulators and energy-based devices may offer promising results for nasal reshaping. However, there is a need for further comparison studies using both objective measures such as 3D photography and physician and patient-reported outcomes, prior to establishing best practices for these techniques.

Petroleum jelly: A comprehensive review of its history, uses, and safety.

Petrolatum, also known as petroleum jelly, is a widely used topical agent, with a variety of uses in dermatology. Despite its popularity, many myths surround this ubiquitous dermatologic staple. This review details the history of petrolatum and how it is manufactured as well as how its biologic properties make it a great moisturizer. Additionally, data on its potential for flammability, allergenicity, and comedogenicity are detailed, dispelling misconceptions about petrolatum use around oxygen and as a cause of acne. The uses and benefits of petrolatum in dermatology are wide-ranging-a patch test instrument, a vehicle for medicated ointments, and a wound care essential. Given its ubiquitous presence, it is important for dermatologists to understand the history, safety profile, and myths surrounding this humble skincare staple.

Expanding and Strengthening Your Referral Network.

Dermatology referral utilization is increasing, with 15% of dermatology-related visits by primary care resulting in a dermatology referral. Given this, both strengthening an expanding a referral is a key component of a successful dermatology practice. In particular, effective communication is essential for efficient patient-oriented coordinated care. Written and/or verbal communication can help build a strong communication network and, in some instances, can be applied toward Merit-based Incentive Payment System (MIPS) reporting and billing for coding families that incorporate the coordination of care. Reaching out directly to referring clinics has also been shown to increase the quantity of referrals. This can include providing clinics with patient handouts on your clinic, education on what information is prioritized within the referral, and educating staff on how to complete their referrals effectively and efficiently. Social media can play an important role in referrals, especially for patients looking for cosmetic care. There are many different platforms, and these can serve as a marketing tool for physicians looking to bring in new patients.

Interleukin 1ß and Prostaglandin E2 affect expression of DNA methylating and demethylating enzymes in human gingival fibroblasts.

Periodontitis is a common chronic inflammatory condition that results in increased levels of inflammatory cytokines and inflammatory mediators. In addition to oral disease and tooth loss, it also causes low-grade systemic inflammation that contributes to development of systemic conditions including cardiovascular disease, pre-term birth, diabetes and cancer. Chronic inflammation is associated with epigenetic change, and it has been suggested that such changes can alter cell phenotypes in ways that contribute to both ongoing inflammation and development of associated pathologies. Here we show that exposure of human gingival fibroblasts to IL-1ß increases expression of maintenance methyltransferase DNMT1 but decreases expression of de novo methyltransferase DNMT3a and the demethylating enzyme TET1, while exposure to PGE2 decreases expression of all three enzymes. IL-1ß and PGE2 both affect global levels of DNA methylation and hydroxymethylation, as well as methylation of some specific CpG in inflammation-associated genes. The effects of IL-1ß are independent of its ability to induce production of PGE2, and the effects of PGE2 on DNMT3a expression are mediated by the EP4 receptor. The finding that exposure of fibroblasts to IL-1ß and PGE2 can result in altered expression of DNA methylating/demethylating enzymes and in changing patterns of DNA methylation suggests a mechanism through which inflammatory mediators might contribute to the increased risk of carcinogenesis associated with inflammation.
