Although outcomes for infants with complex single ventricle heart defects have steadily improved in recent decades, there is still a significant risk for mortality and morbidity during the interstage period between stage 1 Norwood hospitalization discharge and stage 2 palliation. Home monitoring programs, which involve parental surveillance of daily weight and oxygen saturations during the interstage period, have been shown to significantly improve survival rates. This article describes the potential risk factors or causes of interstage mortality and reviews the role of home monitoring in early detection and potential prevention of adverse outcomes.

Objective: A 730 nm picosecond-domain laser was developed to improve the clearance of pigmented lesion and reduce adverse events. This study assessed the safety and efficacy of this system for the clearance of lentigines and explores how the short picosecond pulses interact with tissue via histology. Study Design and Methods: Twenty subjects with Fitzpatrick skin types II-IV were enrolled in this prospective, IRB-approved study. Four treatments were administered using a 730 nm picosecond-domain laser. Pre-and posttreatment photos were assessed by blinded reviewers at 4-and 12-week follow-up visits, using a 5-point clearance scale. Subject satisfaction was measured using a 5-point scale. Investigator Global Improvement Score (IGIS) was performed at the 4-and 12-week follow-up visits, using an 11-point clearance scale. Subject pain level was measured using an 11-point scale (no pain [0], extreme pain [10]). Histology of 730 and 532 nm picosecond pulses was compared with 755 and 532 nm nanosecond pulses. Results: Sixteen subjects with a total of 118 discontinuous treatment areas, each comprised of 1-20 lesions, completed all study visits. Thirty body regions were studied, including arms (6), hands (16), scalp (1), forehead (2), face (3), and back (2). Spot sizes ranging from 2 to 5 mm diameters were used with fluences ranging from 0.8 to 4.0 J/ cm 2 . Mean pain score was 3.6 of 10 for all four treatments. Ninety-nine percent of randomly paired 4-week posttreatment images and 100% of 12-week posttreatment images were correctly identified from their respective baseline images by three blinded reviewers. Mean IGIS demonstrated scores of 6.7 and 7.0 at 4-and 12-week follow-up visits, respectively. At the 4-and 12-week follow-up visits, 76% and 73% of subjects, respectively, were satisfied to highly satisfied. The mean clearance score for all 118 treatment areas was 3 of 4 in follow-up visits. At 12-week follow-up, 36% of 118 treatment areas had a clearance score of 4, and 38% had a clearance score of 3. Post treatment, there was typical erythema, edema, dryness, crusting, and itching but negligible purpura, no pinpoint bleeding, blistering or scarring, and no significant hyperpigmentation or hypopigmentation. Histology showed diffuse, focal epidermal vacuolization ~5-10 µm in diameter and mild extravasation of erythrocytes with 730 nm picosecond pulses, while diffuse epidermal vacuolization was observed with coalescence of vacuoles (~20-100 µm), junctional clefting and mild extravasation of erythrocytes with 755 nm nanosecond pulses. Picosecond pulses of the wavelength of 532 nm produced diffuse, focal epidermal vacuolization and larger dermal vacuoles to depths of 500 µm, while 532 nm nanosecond pulses produced diffuse epidermal vacuolization with coalescence of vacuoles and marked dermal hemorrhage. Conclusion:This study demonstrated the potential of a new 730 nm picoseconddomain laser for the clearance of lentigines. The results showed good clearance with no adverse events and good subject satisfaction in patients wi...

BACKGROUND Aesthetic muscle stimulation (AMS) using high-intensity electromagnetic field (HIFEM) targets skeletal muscle neurons, causing muscle hypertrophy and loss of adipose tissue, thereby cultivating a sculpted physique. Many studies have evaluated AMS for noninvasive body contouring; however, the efficacy, safety, and long-term data remain unclear. OBJECTIVE To critically evaluate the current literature on the use of electromagnetic muscle stimulation for body contouring and provide a consensus on patient selection and long-term efficacy of AMS. MATERIALS AND METHODS PubMed and Embase were searched using the terms: "HIFEM," "Electromagnetic therapy," and "muscle" or "Electrical stimulation muscle treatments" and "aesthetics." Studies involving the use of muscle stimulation for nonaesthetic/dermatologic, in vitro studies or studies involving animals were excluded. RESULTS Twenty studies in total were included [9 moderate-quality, 8 low-quality, and 3 very low-quality studies] based on the Grading of Recommendations, Assessment, Development, and Evaluation scale, representing 521 patients. Body sites evaluated included the abdomen (378 patients), buttock (156 patients), arms (22 patients), and calves (15 patients). CONCLUSION Electromagnetic muscle stimulation represents an effective therapeutic intervention for abdominal contouring that yields increased muscle thickness, and reduced abdominal fat thickness, for up to 1 year after treatment. Larger, controlled studies are needed to determine the efficacy of electromagnetic muscle stimulation alone for contouring of buttocks, thighs, arms, and calves.

Alopecia, the loss of hair on the scalp and/or body, experienced by millions of people worldwide, can be a very debilitating condition. Specifically, androgenetic alopecia (AGA), commonly known as male or female pattern baldness, is the most common form of hair loss. In the African diaspora, oils have traditionally been used to promote hair growth and recently, the application of hair oils to the scalp for the treatment of alopecia has become increasingly popular. With the recent surge of hair oil usage in the Black community, more research is needed to determine the efficacy of hair oils, as most studies have primarily used mice subjects. This article reviews the existing literature to better understand the use of hair oils in the treatment of androgenetic alopecia. Specifically, we investigate the popular carrier oils, castor oil, and pumpkin oil as well as the essential oils, lavender, peppermint, rosemary, and tea tree oil.
