RESUMO

OBJECTIVE: The authors measured implementation of Zero Suicide (ZS) clinical practices that support identification of suicide risk and risk mitigation, including screening, risk assessment, and lethal means counseling, across mental health specialty and primary care settings. METHODS: Six health care systems in California, Colorado, Michigan, Oregon, and Washington participated. The sample included members ages ≥13 years from 2010 to 2019 (N=7,820,524 patients). The proportions of patients with suicidal ideation screening, suicide risk assessment, and lethal means counseling were estimated. RESULTS: In 2019, patients were screened for suicidal ideation in 27.1% (range 5.0%-85.0%) of mental health visits and 2.5% (range 0.1%-35.0%) of primary care visits among a racially and ethnically diverse sample (44.9% White, 27.2% Hispanic, 13.4% Asian, and 7.7% Black). More patients screened positive for suicidal ideation in the mental health setting (10.2%) than in the primary care setting (3.8%). Of the patients screening positive for suicidal ideation in the mental health setting, 76.8% received a risk assessment, and 82.4% of those identified as being at high risk received lethal means counseling, compared with 43.2% and 82.4%, respectively, in primary care. CONCLUSIONS: Six health systems that implemented ZS showed a high level of variation in the proportions of patients receiving suicide screening and risk assessment and lethal means counseling. Two opportunities emerged for further study to increase frequency of these practices: expanding screening beyond patients with regular health care visits and implementing risk assessment with lethal means counseling in the primary care setting directly after a positive suicidal ideation screening.

RESUMO

Most patients with suicide risk do not receive recommendations to reduce access to lethal means due to a variety of barriers (e.g., lack of provider time, training). Determine if highly efficient population-based EHR messaging to visit the Lock to Live (L2L) decision aid impacts patient-reported storage behaviors. Randomized trial. Integrated health care system serving Denver, CO. Served by primary care or mental health specialty clinic in the 75-99.5th risk percentile on a suicide attempt or death prediction model. Lock to Live (L2L) is a web-based decision aid that incorporates patients' values into recommendations for safe storage of lethal means, including firearms and medications. Anonymous survey that determined readiness to change: pre-contemplative (do not believe in safe storage), contemplative (believe in safe storage but not doing it), preparation (planning storage changes) or action (safely storing). There were 21,131 patients randomized over a 6-month period with a 27% survey response rate. Many (44%) had access to a firearm, but most of these (81%) did not use any safe firearm storage behaviors. Intervention patients were more likely to be categorized as preparation or action compared to controls for firearm storage (OR = 1.30 (1.07-1.58)). When examining action alone, there were no group differences. There were no statistically significant differences for any medication storage behaviors. Selection bias in those who responded to survey. Efficiently sending an EHR invitation message to visit L2L encouraged patients with suicide risk to consider safer firearm storage practices, but a stronger intervention is needed to change storage behaviors. Future studies should evaluate whether combining EHR messaging with provider nudges (e.g., brief clinician counseling) changes storage behavior.ClinicalTrials.gov: NCT05288517.

RESUMO

This study aimed to prospectively evaluate the effectiveness, patient satisfaction, and early adverse events of using the hyaluronic acid filler VYC-20L for the treatment of infraorbital hollowing. A total of 21 participants underwent injection of VYC-20L. FACE-Q satisfaction surveys before and after treatment along with early adverse events surveys were conducted. Pre- and posttreatment photos were graded, and the Allergan Infraorbital Hollows Scale was used to assess the difference in infraorbital hollowing. The results showed infraorbital hollowing improvement with VYC-20L was significant (p < 0.001). FACE-Q Satisfaction with Eyes scores on average were 27 points higher after treatment (p < 0.001). The mean FACE-Q Satisfaction with Decision score was 74.1%. The most common short-term adverse symptoms were tenderness (67%), swelling (62%), and bruising (52%). This study concludes that VYC-20L is an effective nonsurgical treatment option for infraorbital hollowing with high patient satisfaction.

RESUMO

Facial aging is a multifactorial process with many articles over decades supporting various theories of varying causes. It is generally thought that aging occurs as a combination of changes in skin quality, gravitational descent of tissue with interaction of retaining ligaments on the ptotic tissue, and facial volume loss or the appearance of volume loss. The most significant cause of volume loss is skeletal remodeling and bone loss, which manifests as characteristic shadows and hollows on the face in conjunction with soft tissue changes that are yet to be completely elucidated.

RESUMO

Increased rates of clinically significant internalizing disorders (obsessive compulsive disorder, anxiety, and depression) have been demonstrated in males with Duchenne muscular dystrophy, and a Duchenne muscular dystrophy neuropsychiatric syndrome has been suggested. Although symptoms of depression are widely recognized, some of the other internalizing symptoms are less frequently identified. Through a retrospective chart review of 107 males with Duchenne muscular dystrophy, we identified 15 patients with obsessive compulsive disorder spectrum symptoms; 11 of those also had anxiety symptoms. Many of these patients received selective serotonin reuptake inhibitor treatment, commonly noting improvement in symptoms. Here we describe the clinical features of several patients in detail to facilitate early recognition and consideration for treatment for patients with Duchenne muscular dystrophy and internalizing psychiatric symptoms. The results of this cohort showed a significantly increased rate of obsessive compulsive disorder spectrum symptoms (14%) compared to the general population.

RESUMO

IMPORTANCE: Hyaluronic acid filler can be safely used as a soft-tissue filler for correction of infraorbital hollowing. It has a high overall patient satisfaction profile among patients. OBJECTIVE: To report safety and patient satisfaction outcomes of Juvéderm Voluma XC for correction of infraorbital hollows. DESIGN, SETTING, AND PATIENTS: This was a retrospective observational study performed at a private ambulatory facial plastic and reconstructive surgery practice. Participants were all patients 21 to 85 years old who presented to our practice and underwent Juvéderm Voluma XC treatment for correction of infraorbital hollows as a singular intervention from February 2016 to March 2017. INTERVENTIONS: Injection of Juvéderm Voluma XC to the tear trough, nasojugal fold, and/or palpebromalar groove. MAIN OUTCOMES AND MEASURES: Primary outcome measures include the number of recorded short- and long-term adverse events, need for additional treatment, and patient questionnaire FACE-Q scores. RESULTS: A total of 202 eyes were treated in 101 patients with a mean follow-up of 12 months. Patients were principally female (90 [89%]) with an average age of 54 years (range, 21-85 years). Most patients (99) had Fitzpatrick grade 1 to 4 skin type (98%) and had an infraorbital hollows score of 2 to 4 (89 [88%]). The average initial treatment volume was 1 mL with 18 patients (18%) requiring additional treatment within 3 months. The average time until additional treatment was 35.7 days. Adverse effects include bruising (in 10 [10%], contour irregularities (2 [2%]), swelling (3 [3%]), and Tyndall effect (1 [1%]). Hyaluronidase was required in 3 patients (3%). Forty-one patients completed the FACE-Q Satisfaction With Eyes survey, and 42 patients completed the FACE-Q Satisfaction With Decision survey (41% and 42%). Overall mean (SD) patient satisfaction (based on FACE-Q scores) was 71.1% (27.3) and 65.6% (31.3), respectively. CONCLUSIONS AND RELEVANCE: Juvéderm Voluma XC has a high patient satisfaction profile and an acceptable safety profile for the correction of infraorbital hollowing. LEVEL OF EVIDENCE: 4.

RESUMO

IMPORTANCE: Incision placement and design in rhytidectomy is critical for patient satisfaction. OBJECTIVE: To evaluate the aesthetic outcome of W-plasty vs traditional straight-line (SL) trichophytic closure techniques on posterior occipital hairline scars in rhytidectomy. DESIGN, SETTING, AND PARTICIPANTS: A retrospective cohort study was conducted at the Buckingham Center for Facial Plastic Surgery. Clinical history and operative reports were reviewed for 46 patients who underwent rhytidectomy (23 using W-plasty and 23 using SL technique) between June 1, 2014 and August 31, 2015. Blinded photographic analysis of 1-year postoperative photographs was performed. INTERVENTIONS: The posterior occipital hairline incision was primarily closed with either a W-plasty or SL trichophytic technique. MAIN OUTCOMES AND MEASURES: Standard photographs of the posterior occipital incision site obtained after the 1-year postoperative mark were reviewed and scored in a blinded fashion by 3 nonphysician medical staff members using a modified Manchester Scar Scale (MSS: from 0 [best possible outcome] to 24 [worst possible outcome]). Interrater reliability was assessed via Cronbach α testing. RESULTS: There were 23 patients in each group. The W-plasty and SL groups were similar in terms of age (mean [SD] age, 59.6 [6.3] years and 64.1 [7.3] years, respectively), sex (21 [91%] and 21 [91%] women, respectively), race-ethnicity, and absence of risk factors (smoking and diabetes) predisposing to poor wound healing (0 and 0 smoking/diabetes, respectively). Mean (SD) follow-up times for the W-plasty and SL groups were 388 (38.8) and 475 (100.1) days, respectively. No statistical difference was demonstrated in the mean aggregate MSS scores from all evaluators between the W-plasty group and the SL group (reviewer 1: 5.69 vs 5.86, P = .60; reviewer 2: 10.09 vs 9.56, P = .65; and reviewer 3: 5.30 vs 6.17, P = .08). Overall interrater reliability for the MSS scores was 0.56. CONCLUSION AND RELEVANCE: Primary W-plasty and SL trichophytic closures in the posterior occipital hairline appear to yield highly acceptable and similar cosmetic outcomes under objective blinded evaluation. These techniques can be used with success to help minimize conspicuous scarring after rhytidectomy. LEVEL OF EVIDENCE: 3.

RESUMO

As the popularity and acceptance of facial and cervical rejuvenation procedures grows, surgeons are increasingly encountering patients with less favorable anatomical characteristics for rhytidectomy. These patients will typically display an obtuse cervicomental angle, underprojected chin, excess cervical adiposity, and platysmal banding, in addition to ptotic submandibular glands, tenacious jowls, and prejowl volume deficits. Recognition of these problems and the correct application of available techniques to address the difficult neck in facelifting are critical in maximizing success.

RESUMO

Facial volume loss has become widely accepted as one of the contributing factors in global facial aging. Some have even suggested that bony, muscular, fatty, and dermal/epidermal changes are more integral in the aging process than gravitational influence. Although detractors of autologous fat transfer persist, facial autologous fat transfer has become widely utilized as one option for volume restoration. Various techniques in harvesting, processing, and injecting autologous fat have been debated at length without clear guidelines emerging to maximize outcomes. This article aims to present one surgeon's experience in successful fat grafting philosophy and technique. Areas covered will include preparation, harvesting, processing, and injection techniques. The injection techniques are organized by facial region and into the general philosophy and thinking regarding the facial region as well as the specific technique that has been utilized over 7 years and hundreds of successful procedures.

RESUMO

The next three articles in this issue take a unique approach to discussing volumetric restoration. Robert Glasgold has provided an assessment for each facial region and five different renowned authors (TK, SPS, RF, SML, and EFW) have been asked to speak on a particular volumetric product, of which they are considered an expert, as it applies to the different regions of the face. The articles are broken into the following: (1) upper third which corresponds to the upper eyelid, brow, temple, and forehead; (2) middle third which will cover lower eyelid, cheek, and perioral area; and (3) lower third which discusses the marionette, prejowl, and jawline. Our hope is that by placing differing opinions of experienced authors, organized by facial region together, the reader will have the opportunity to more readily compare the options. The contributing authors and their product area are as follows: Theda Kontis, MD-hyaluronic acid; Steve Smith, MD-calcium hydroxyl appetite; Rebecca Fitzgerald, MD-poly-L lactic acid; Sam Lam, MD-polymethyl methacrylate; and Edwin Williams, MD-Autologous Fat Transfer. If the author included general comments on the product, they are included in the article on the upper face only and are not repeated. Please note that other individuals may also have significantly assisted in the production of these articles, but those listed above are the senior authors.

RESUMO

This is the second of the three articles discussing volumetric rejuvenation of the face. The previous article, Volume Rejuvenation of the Facial Upper Third, focused on the upper one-third of the face while this article focuses on the middle one-third, primarily the lower eyelid, cheek, and perioral area. Again, the authors (RG, TK, SPS, RF, SL, and EFW) from the upper face article have provided a summary of rejuvenation utilizing a product of which they are considered an expert. Robert Glasgold has provided volumetric analysis of the region as an introduction.

RESUMO

This is the third and final article discussing volumetric rejuvenation of the face. The previous two articles, Rejuvenation of the Upper Third and Management of the Middle Third, focused on the upper two-thirds of the face while this article focuses on the lower face, including the marionette area, jawline, and neck. Again, the authors of the previous two articles have provided a summary of rejuvenation utilizing a product of which they are considered an expert. Robert Glasgold has provided volumetric analysis of the region as an introduction.

RESUMO

Facial volume loss is an important component of facial aging and tends to present at an earlier age than other aspects of aging. Several surgical and nonsurgical products and techniques are available to replace volume loss associated with aging. One surgical technique uses a patient's fat cells to replace or augment volume deficiency. Poly-L-lactic acid (PLLA) injection is a nonsurgical option. This article compares these 2 volume augmentation procedures and discusses characteristics of facial aging, the consultation process involved in assessing individual volume loss, procedure details of autologous fat grafting and PLLA injection, the decision of PLLA versus autologous fat, and patient outcomes.

RESUMO

Past descriptions of vascular lesions often confused vascular malformations and hemangiomas using interchangeable definitions which led to inappropriate treatment and inconsistency in the medical literature. The work of Mulliken and Glowacki systematically delineated the difference between hemangiomas and the multiple varieties of vascular malformations. Hemangiomas are in fact as the suffix "oma" suggests true tumors exhibiting cellular proliferation on histology. Additionally, treatment has been clouded by numerous reports in the literature of near universal complete spontaneous resolution and conversely arguments that every lesion demands treatment. More recently, thoughtful studies of the natural course of hemangiomas have been completed, algorithms for intervention versus observation proposed, and effective safe treatment plans devised. The following article will be presented in two sections. The first section will review the diagnosis and natural history of hemangiomas as appreciated in modern literature and compare this to a review of historical articles. This information will then be used to describe a rational and thoughtful algorithm for observation or intervention and recommend appropriate treatment options. Special emphasis will be given to surgical technique and several cases of late involuting hemangiomas of the face will be presented.

RESUMO

Hemangiomas are the most common tumor of infancy and childhood, affecting approximately 10% of infants by the age of 1 year. The diagnosis can nearly always be made by the patient's history and findings on physical examination. Prior to the classification system outlined by Mulliken and Glowacki, the natural course of hemangiomas was poorly understood and treatment was inconsistent, ranging from benign neglect to deforming surgical intervention. However, with an improved understanding of the natural course of hemangiomas, as well as advances in anesthesia, laser technology, medical therapy, and surgical methods, an aesthetic approach to facial hemangiomas was developed by the senior author (E.F.W.) and is reviewed in this article.

RESUMO

OBJECTIVE: To determine the optimal design of an O-to-Z flap for closure of facial skin defects. METHODS: Prospective cadaver study. Multiple 2-cm-diameter circular skin defects were created in fresh cadavers. Three types of O-to-Z flaps were designed, varying the angle of a curved line about concentric radii of the defect: acute, intermediate, or wide angle flap. The tension of closure of each was measured and compared at different lengths of incision and extents of undermining. RESULTS: The acute angle flap had a significantly lower closing tension at all lengths of incision and extents of undermining than the intermediate and wide angle flaps. Increasing the amount of undermining alone without incising the flap did not significantly decrease the closing tension. Incising the acute angle flap to 4 radii created a nearly tension-free closure. CONCLUSIONS: The optimal design for reducing tension of the O-to Z flap is an acute angle flap. The optimal length of incision and undermining necessary to minimize closing tension is discussed.
