RESUMO

BACKGROUND: Over the past decade, 2 major modalities for noninvasive skin tightening have emerged: monopolar capacitive-coupled radiofrequency (MRF) and microfocused ultrasound with visualization (MFU-V). Up to date, no comparative clinical trials have been performed. OBJECTIVE: To compare the efficacy and safety of MRF versus MFU-V for the lifting and tightening of the face and neck. MATERIALS AND METHODS: Twenty subjects with mild to moderate skin laxity received MFU-V over one-side of the face and MRF over the other side of the face at the same time. Subjects were followed for 6 months. RESULTS: Both MRF and MFU-V led to a decrease in the Fasil Face and Neck Laxity Grading Scale (FLR). These differences became significant at Day 30 and remained significantly improved through Days 90 and 180 in both groups. There was no statistically significant difference in the FLR Scale between MRF-treated and MFU-V-treated sides. Subjects' Global Aesthetic Improvement Scale showed improvement at Day 30, 90, and 180. CONCLUSION: Both MRF and MFU-V led to significant improvement in face and neck laxity. There were no statistical differences between MRF and MFU-V in standardized investigator measures of face and neck laxity, patient satisfaction, and adverse events.

RESUMO

BACKGROUND: Although transcutaneous temperature-controlled radiofrequency (TTCRF) may effectively treat vulvovaginal laxity (VVL), atrophic vaginitis (AV), orgasmic dysfunction (OD), and stress urinary incontinence (SUI), there is a lack of histopathologic evidence to validate its use. OBJECTIVE: Evaluate clinical and histological changes induced by vulvovaginal TTCRF. MATERIALS AND METHODS: This was a prospective, nonrandomized trial. Ten female subjects with mild-to-moderate VVL, with or without AV, OD, and/or SUI underwent 3 TTCRFs at 4-week intervals. Five subjects underwent pre- and post-treatment biopsies of the labia majora and vaginal canal for histology. Assessments were performed at baseline and Days 10, 30, 60, and 120. RESULTS: Investigator-rated VVL improved significantly from baseline to Day 10, with improvement maintained through Day 120 (p = .001 and .001, respectively). Sexual satisfaction improved significantly by Day 60 (p = .001). Improvement in AV reached significance at Day 120 (p = .048). Although OD and SUI improved steadily, the difference in improvement did not reach statistical significance. Histology revealed that post-treatment increases in collagen, elastin, vascularity, and small nerve fibers. CONCLUSION: Transcutaneous temperature-controlled RF resulted in significant improvements in AV, VVL, and sexual satisfaction with milder improvements in OD and SUI. Post-treatment histology demonstrated neocollagenesis, neoelastogenesis, neoangiogenesis, and the first reported finding of TTCRF-related neurogenesis.

RESUMO

BACKGROUND: The nonablative, fractional, 1,927-nm diode laser is theoretically a safe and effective treatment for hyperpigmentation and melasma in darker skin and may potentiate topical cosmeceutical delivery. OBJECTIVE: To evaluate the use of a nonablative, fractional, 1,927-nm diode laser with and without topical 2% hydroquinone (HQ) cream for moderate-to-severe facial hyperpigmentation in Fitzpatrick skin Types III-V. METHODS: Forty adults underwent 4 laser treatments at 2-week intervals and were randomized to daily application of 2% HQ cream or moisturizer. Follow-ups were conducted 4 and 12 weeks after the final laser treatment. RESULTS: Hydroquinone and moisturizer groups demonstrated Mottled Pigmentation Area and Severity Index improvements of approximately 50% at post-treatment Weeks 4 and 12. Blinded investigator-assessed hyperpigmentation and photodamage improved significantly for both the groups at post-treatment Weeks 4 and 12. Subject satisfaction improved significantly in both the groups by post-treatment Week 4. Although investigator-rated Global Aesthetic Improvement Scale scores were significantly better in the HQ group at post-treatment Week 12, satisfaction was higher among those using moisturizer. No adverse events were noted. CONCLUSION: The nonablative, fractional, 1,927-nm diode laser produced significant improvement in hyperpigmentation in Fitzpatrick skin Types III-V by 4 weeks, with maintenance of results at 12 weeks after treatment even without HQ.

RESUMO

BACKGROUND: "Skin boosting" with injections of hyaluronic acid has been demonstrated to improve aged skin. OBJECTIVE: The aim of this study was to determine the efficacy and safety of small-particle hyaluronic acid with lidocaine (SP-HAL) microaliquots for the correction of fine lines of the cheeks. MATERIALS AND METHODS: Twenty subjects with mild to moderate static mid to lower cheek rhytides were enrolled. The right or left cheek was randomized to receive 1 mL of SP-HAL using a microdroplet technique, with the contralateral cheek treated with sham injection of sterile normal saline. The degree of cheek wrinkling and elastosis based on the Fitzpatrick-Goldman Wrinkle and Elastosis Scale was assessed at baseline and 7, 14, 30, 90, and 180 days after treatment. Subjects rated their satisfaction at days 90 and 180. RESULTS: Fourteen patients completed the study. There were no statistically significant improvements in wrinkling or elastosis of the SP-HAL-treated cheek or control cheek at any time point. In addition, there were no significant differences in wrinkling, elastosis, or patient satisfaction between the treatment cheek and control cheek. CONCLUSION: One treatment of intradermal microdroplet injections of SP-HAL to the mid to lower cheek failed to show superiority over normal saline in improving clinical signs of skin wrinkling and elastosis.

RESUMO

BACKGROUND: Infraorbital dark circles result from a combination of factors. The fractionated picosecond 755 nm alexandrite laser and dual wavelength picosecond Nd:YAG laser have not been examined as a method of addressing infraorbital hyperpigmentation. OBJECTIVE: To determine the efficacy and safety of treatment of infraorbital dark circles using fractionated picosecond 755 nm and dual wavelength picosecond Nd:YAG laser. METHODS AND MATERIALS: These trials did not utilize a comparative design; rather, these were separate, prospective, open-label, evaluator-blinded trials utilizing two treatment regimens: (i) 19 adult subjects were treated in a single session with the dual wavelengths of 532 nm and 1,064 nm in consecutive passes using the fractionated lens; (ii) 10 adult subjects were treated using the picosecond 755 nm laser via the fractionated lens in three treatment sessions at 3 week intervals. Subjects in both studies were followed-up for blinded-investigator assessment of infraorbital hyperpigmentation, adverse events, and improvement compared to baseline. RESULTS: The dual wavelength picosecond Nd:YAG laser, blinded-investigator assessment did not demonstrate a significant improvement in infraorbital hyperpigmentation at day 60 (P = 0.16). The picosecond 755 nm alexandrite laser significantly improved infraorbital hyperpigmentation by day 42, with improvement maintained through day 132 (P = 0.07 and 0.00001, respectively). Adverse events were mild and temporary. CONCLUSION: A single treatment with the fractionated picosecond 1,064/532 nm lasers did not produce a significant improvement in infraorbital hyperpigmentation. A series of three treatments with the fractionated picosecond 755 nm laser resulted in significant improvement in hyperpigmentation. Lasers Surg. Med. 50:45-50, 2018. © 2017 Wiley Periodicals, Inc.

RESUMO

Purpose: Though hydroquinone (HQ) remains the gold standard for treatment of hyperpigmentation, concerns about its safety have prompted the development of HQ-free topical skin lightening systems. OBJECTIVE: To compare the efficacy and tolerability of a new HQ-free system and a popular HQ-based system for the improvement of facial hyperpigmentation and photoaging in darker skin types. METHODS: This investigator-blinded trial randomized 30 subjects of Fitzpatrick skin types III to VI with moderate to severe hyperpigmentation to a new 7-product HQ-free system or a 7-product HQ-based system for 12 weeks. At 4, 8, and 12 week follow-up visits, a blinded investigator assessed efficacy and tolerability using standardized scales. Subjects also performed a self-assessment at each visit. SUMMARY: Both the HQ-free and HQ-based systems produced significant improvements in Overall Hyperpigmentation that were sustained through week 12 (P=0.008, 0.0003). The HQ-based system demonstrated better improvement in overall hyperpigmentation at weeks 4, 8, 12 (P=0.01, 0.001, 0.003, respectively). Mottled Pigmentation Area Severity Index (MoPASI) scores improved with both systems (P=0.02, 0.01), with no statistically significant differences between the two treatment groups. Subject-rated hyperpigmentation was not different between groups. Subjects reported significantly more discomfort with the HQ-free system at week 8 (P=0.02); otherwise, measures of irritation were the same between groups. All irritation was described as mild to moderate. At week 12, 100% of subjects in the HQ-free group and 92.3% of subjects in the HQ-based group were satisfied with their outcome. CONCLUSION: Both a new HQ-free skincare system and a widely-available HQ-based system improved hyperpigmentation in Fitzpatrick skin types III to VI. Though the HQ-based system produced greater improvement in hyperpigmentation when compared to the HQ-free system, there was no difference in MoPASI scores between the treatment groups. Subjects were satisfied with both treatments and reported only mild to moderate irritation using either system.

RESUMO

BACKGROUND: A topical healing system containing a combination of active ingredients including a tripeptide and hexapeptide (TriHex Technology™) has been found to stimulate neoelastogenesis and neocollagenesis. OBJECTIVE: Evaluate the use of the tripeptide/hexapeptide topical system following fractionated CO2 laser resurfacing compared to a bland ointment and cream. PATIENTS/METHODS: In this single-blinded, randomized study, 15 female subjects aged 45-70 years underwent laser resurfacing of the face. Subjects were randomized to use of the tripeptide/hexapeptide system (n=10) or a bland dimethicone-based ointment and petrolatum-based cream (n=5) from 3 weeks pre- until 12 weeks postprocedure. A blinded investigator graded erythema, edema, crusting, exudation, and healing on postprocedure days 1, 3, 4, 7, 28, and 84. A photodamage/wrinkle scale was completed on days 28 and 84. Subjects performed symptomatology grading on days 1 through 14 and completed self-assessments at days 28 and 84. RESULTS: Data from 14 subjects were analyzed. Blinded-investigator-rated healing was better for the tripeptide/hexapeptide system, reaching statistical significance at day 7. The tripeptide/hexapeptide group demonstrated less erythema and exudation during the first postprocedure week, reaching significance at day 3. On days 1 through 14, subjects using the tripeptide/hexapeptide system reported less tenderness and burning/stinging, also reaching significance on day 3. At day 84, subjects using the tripeptide/hexapeptide system reported higher satisfaction and were more likely to recommend the treatment to others. CONCLUSION: Postresurfacing use of a tripeptide/hexapeptide system proved effective and well-tolerated. Subject satisfaction was greater among those using this system, which may indicate an improved patient experience following laser resurfacing.

RESUMO

BACKGROUND: Neuromodulator injection procedures are an effective treatment for moderate-to-severe facial wrinkles, but do not address the superficial fine lines and wrinkles caused by age-related loss of intrinsic hyaluronic acid levels in the epidermis. OBJECTIVE: In this study, the authors assess overall facial skin quality and patient satisfaction when combining topical treatment with the a topical cosmetic serum (HA5) and applying to the entire face following a pre-elected neuromodulator injection treatment to the lateral canthal areas. METHODS AND MATERIALS: Twenty female subjects aged 36 to 63 years with moderate-to-severe under-the-eye fine lines and/or wrinkles enrolled in the study. HA5 was applied the entire face at baseline immediately post-injection and twice daily for eight weeks. Clinical assessments were conducted at baseline; 15 minutes post-procedure; and at Weeks 2, 4, and 8. RESULTS: Statistically significant improvements were observed immediately post-procedure and after eight weeks, along with high patient satisfaction. CONCLUSION: The combination of topical serum and injectable procedure provided a rapid onset of improvements in fine lines/wrinkles appearance and skin texture and long-term overall improvements in areas not treated by the injection. These results support how this novel combination can provide physicians with a comprehensive approach to optimize patient outcomes.

RESUMO

With the rapid increase in patients seeking cosmetic treatments, the variation in responses of lightly pigmented skin versus darkly pigmented skin has become increasingly apparent. Despite extensive treatment options in patients with skin of color, there is a paucity of well-designed studies performed on this patient population. The lack of research is concerning, as it is well documented that patients with darker skin types are at an increased risk of adverse events when treated with many of the available modalities used in cosmetic procedures. Fortunately, by combining a variety of treatments, these risks may be abrogated, and combination treatments may be a promising regimen for a wide variety of cosmetic complaints. An overview and evaluation of the research of combination therapy in skin of color is presented.

RESUMO

BACKGROUND: Aging, childbearing, and hormonal changes can lead to vulvovaginal laxity and mucosal atrophy that negatively affect a woman's quality of life. As more minimally and noninvasive options for genital rejuvenation become available in the outpatient setting, it becomes increasingly important for the dermatologic surgeon to be familiar with these popular procedures. OBJECTIVE: To familiarize dermatologists with the nonsurgical options available for female genital rejuvenation, patient motivations for pursuing these procedures, relevant anatomy, and potential adverse events. MATERIALS AND METHODS: A MEDLINE search was performed on nonsurgical female genital rejuvenation from 1989 to 2015, and results are summarized. RESULTS: Reports of nonsurgical female genital rejuvenation procedures using fractional carbon dioxide lasers, nonablative lasers, monopolar radiofrequency devices, hyaluronic acid fillers, and fat transfer are concisely summarized for the practicing dermatologist. CONCLUSION: Review of the literature revealed expanding options for nonsurgical female genital rejuvenation.

RESUMO

Congenital hemangiomas (CH) are benign vascular neoplasms that proliferate in utero and have completed development by birth. Two subtypes of CH are recognized: rapidly involuting congenital hemangiomas (RICH) and non-involuting congenital hemangiomas (NICH). Involution of the RICH subtype often begins in the first weeks of life. NICH does not involute, allowing the distinction between RICH and NICH. We report a case of an infant with RICH occurring on the scalp, examined at birth and followed for 26 weeks.

RESUMO

Up until now, no objective scale has existed to evaluate chest wrinkles and assess the efficacy of treatment. This study was designed to validate a new photonumeric wrinkle assessment scale using standardized photographic methodology to obtain reference photographs. Multiple photographs from 28 volunteer subjects with varying degrees of chest wrinkles were evaluated by a study team of two independent physicians. Photographs of 16 subjects representing the full spectrum of chest wrinkle severity were selected and classified using the Fabi-Bolton (F-B) 5-point wrinkle scale (1 = wrinkles absent; 2 = shallow but visible wrinkles; 3 = moderately deep wrinkles; 4 = deep wrinkles, with well-defined edges; 5 = wrinkles very deep with redundant folds). One representative photograph was chosen by study team consensus for each of the five scale points. A second, independent group of evaluators rated the randomly arranged photographs using the F-B wrinkle scale. The numeric results were then tabulated and compared. The F-B wrinkle scale provided a reproducible and effective method for assessing chest wrinkles with very little interrater variability. The F-B wrinkle scale is a reliable tool for the classification of chest wrinkles and evaluation of therapeutic and cosmetic interventions.

RESUMO

Cat-scratch disease (CSD) and bacillary angiomatosis (BA) are caused by a gram-negative bacilli classified under the genus Bartonella (formerly Rochalimaea). Patient history, symptoms, and histopathology often fall along a continuum; therefore, both conditions should be considered in the differential diagnosis. We report a case of an 83-year-old immunocompetent woman who presented with a pyogenic granuloma-like lesion on her dorsal left wrist. The histologic differential diagnosis included an inoculation site from a cat scratch infected with Bartonella and BA. Because the patient had only 1 lesion at the site of a prior cat scratch, the lesion was diagnosed as inoculation bartonellosis. We also review the epidemiologic, clinical, and histopathologic features of CSD and BA.

RESUMO

Early Support (ES) is the flagship government programme aimed at improving multi-agency working with, and supporting enhanced outcomes for, children with a disability 0-3 years and their families. This paper draws on results from the recently completed Department for Education and Skills commissioned national evaluation of ES involving 46 pathfinder projects throughout England. Data were collected by survey at two points in time (9 months apart), by focus groups with service providers and parents, and through secondary data analyses, including exploratory economic evaluation. This paper outlines some of the key findings pertaining to the relationship between integrated children's services and the impact of ES. As such, we address three concerns: what the evidence from ES can tell us about the relationships between universal and targeted provision within integrated children's service structures, the relationship between specific short-term initiatives and their longer-term sustainability within integrated children's services structures and the potential costs and benefits of ES looking forward to its implementation on a national basis within an integrated children's services environment. Although focused primarily on children with a disability in the early years, implications will be drawn for the implementation of Lead Professional Guidance and the Common Assessment Framework more generically.
