Perceived Responsibility for Bariatric Surgery, Eating, and Exercise Behaviors Among Adolescent Bariatric Surgery Candidates.

Background: Adolescents' perceived responsibility for weight management behaviors has yet to be studied in relation to bariatric surgery. The current study examined perceived responsibility to pursue bariatric surgery and engage in specific weight management behaviors among adolescents seeking bariatric surgery and its associations with demographic, family support, and eating disorder symptoms. Methods: Data were collected using retrospective chart review of adolescent bariatric surgery candidates presenting to a tertiary interdisciplinary clinic. Data included demographics and adolescents' self-report of (1) perceived responsibility (i.e., primarily adolescent; primarily parent; shared) for the decision to pursue bariatric surgery and weight management behaviors, (2) family support for eating and exercise behaviors, and (3) eating disorder symptoms. Analyses included one-way analysis of covariance, chi-squared tests, and Kruskal-Wallis tests. Results: Participants reporting primarily teen or shared responsibility for seeking bariatric surgery were older than those reporting primarily parent responsibility (p = 0.023). Teens perceiving primary responsibility for their own healthy eating reported less family encouragement for healthy eating (p = 0.011) and more eating disorder symptoms (p = 0.002) than those reporting primarily parent or shared responsibility. Teens reporting primary responsibility for exercise reported less family encouragement for healthy eating (p = 0.012) compared with those reporting shared responsibility. Conclusions: This study is the first to provide a description of health behavior responsibilities in a sample of adolescents with severe obesity seeking bariatric surgery. Not only will these insights improve our understanding of this population, but it can also inform presurgical discussions with adolescents and their parents.

Primary Dermal Melanoma: A Case Report.

ABSTRACT: Primary dermal melanoma (PDM) is defined as a primary melanoma tumor confined to the dermis, subcutis, or both, without epidermal involvement. The significant overlap of histopathological features in PDM and cutaneous metastatic melanoma makes diagnostic accuracy of PDM challenging. We present a case of a 48-year-old man with a nontender 1.5 × 1.5 cm subcutaneous nodule on the left leg, which had been present for years. Biopsy revealed a dermal tumor with melanocytic differentiation noted to be positive for SOX-10. Additional pathology findings included a high Ki-67 proliferation index and a loss of p16 expression. Pathology reports were consistent with primary tumor stage 4a, and the patient was referred to surgical oncology where examination and workup demonstrated no evidence of the residual lesion representing a metastasis from a primary site. As PDM is histologically indistinguishable from melanoma metastasis to the skin, clues including a history of an evolving subepidermal nodule and exclusion of previous or concurrent melanomas can assist in its accurate diagnosis. Currently, a consensus on the criteria, staging, and management of PDM does not exist. Poorly defined diagnostic criteria and general lack of awareness of PDM result in high rates of incorrect and late-stage diagnoses. This case report highlights the importance of physician familiarity with PDM to ensure accurate recognition, evidence-based management, and improved patient outcomes.

Eating Disorder Symptomatology Among Adolescents Presenting for Bariatric Surgery Candidacy: Examining Differences by Sex and Racial Minority Status.

BACKGROUND: Research on adolescent bariatric surgery candidates is limited by insufficient inclusion of ethnic minorities and males, and lack of consideration of the full spectrum of disordered eating behaviors (i.e., restriction, compensatory behaviors [e.g., purging], overeating/binge eating behaviors). OBJECTIVES: The current study investigated differences in the full range of disordered eating behaviors across sex and ethnicity among adolescents seeking bariatric surgery. SETTING: Teaching hospital, United States. METHODS: Data were collected using retrospective chart review of 79 adolescent bariatric surgery candidates (59% female, 46.8% Hispanic, MBMI = 50.2, SDBMI = 10.0, Mage = 17.3, SDage = 2.02) who had completed the self-reported Eating Disorder Diagnostic Scale for DSM-5 at intake. RESULTS: Approximately 33% of study participants met self-reported criteria for an eating disorder, with 35% endorsing binge eating behaviors and 50% endorsing compensatory behaviors. Few differences in behavior frequencies were observed across sex or racial/ethnic status. CONCLUSIONS: Findings underscore the importance of assessing the full spectrum of disordered eating behaviors among adolescent bariatric surgery candidates.

Two Unusual Cases of Discoid Lupus Erythematosus Associated With Xanthomatized Macrophages.

We present 2 patients with chronic discoid lupus erythematosus (LE) associated with xanthomatized macrophages on light microscopic findings. Skin biopsies revealed hyperkeratotic and atrophic epidermis, vacuolar degeneration of the dermal-epidermal junction, thickened basement membrane, follicular plugging, and perivascular and perifollicular lymphohistiocytic infiltrate. Notably, large collections of lipid-laden histiocytes were observed within the subjacent dermis. The patients denied history of intralesional steroid treatment. The patients did not demonstrate any clinical or laboratory signs of hyperlipidemia, cholestasis, and diabetes mellitus and insipidus. Accumulation of lipid-laden foam cells in cutaneous LE is a rare phenomenon that has been reported in discoid LE and lupus panniculitis, each only once in the literature. It has also been described within lesions of various other dermatoses in patients without lipid, hepatic, or endocrine abnormalities. Its mechanism remains unclear, but it has been hypothesized that intracellular lipids released from degenerating cells contribute to lipidization of mononuclear scavengers. Xanthomatous infiltration in cutaneous LE is an unusual feature, and its presence may not necessarily signify an underlying metabolic disorder.

Unsafe Deposits: Overlapping Cutaneous Manifestations of Porphyria Cutanea Tarda, Ochronosis, Hemochromatosis, and Argyria.

Cutaneous deposition disorders represent an array of conditions resulting from the accumulation of endogenous and exogenous substances within the skin. Many of the deposition diseases resemble each other and can also be confused with disorders not related to deposition. Porphyria cutanea tarda (PCT) results from dysfunction particularly in the fifth enzyme of the heme synthesis pathway, leading to increased skin fragility and bullae among other abnormalities. Ochronosis develops from alkaptonuria or exogenous sources, creating deposition of ocher-colored pigment in the skin. Hemochromatosis is a systemic disorder that can be inherited or acquired, altering skin pigmentation in more than 90% of patients. PCT can be an initial manifestation of hemochromatosis. Argyria is an acquired disorder of silver deposition that can also cause pigmentation similar to ochronosis. These uncommon but not rare disorders may resemble and be confused with each other in multiple ways.

Aberrant tyrosinase expression in an atypical fibroxanthoma: A case report.

Atypical fibroxanthoma (AFX) is a histologic mimicker of a variety of spindle cell neoplasms, and careful microscopic and immunohistochemical evaluation is critical in establishing the correct diagnosis. Here we report the histologic and immunohistochemical work up of a 1 cm nodule involving the left dorsal hand of a 66-year-old patient. Light microscopy revealed fascicles of spindled and pleomorphic cells within the dermis showing increased mitotic activity occurring in the background of sun-damaged skin. There were numerous multinucleated cells with hyperchromatic nuclei and ample finely vacuolated or foamy cytoplasms. There was strong and diffuse CD10 and patchy CD68 expression among the spindled cells and multinucleated cells. The neoplastic cells did not show immunoreactivity against S100, p75-NGFR, HMB-45 or a panel of keratinocytic, vascular and smooth muscle markers. Tyrosinase and Melan-A were not expressed within the spindle cell component of this neoplasm; however, there was tyrosinase expression among numerous multinucleated giant cells. Melan-A expression was also observed among rare multinucleated giant cells. Tyrosinase expression has not previously been reported in AFX.

Interdependent Self-Construal, Self-Efficacy, and Community Involvement as Predictors of Perceived Knowledge Gain Among MMORPG Players.

This study explored the relationship between interdependent self-construal, video game self-efficacy, massively multiplayer online role-playing game (MMORPG) community involvement, and self-reported learning outcomes. The results suggested that self-efficacy and interdependent self-construal were positive and significant predictors of MMORPG community involvement. For its part, MMORPG community involvement was a positive predictor of self-reported learning in both focused and incidental forms. Supplementary analyses suggested that self-efficacy was a comparatively more robust predictor of MMORPG community involvement when compared to self-construal. Moreover, the present data suggest that community involvement significantly facilitated indirect relationships between self-construal, game-relevant self-efficacy, and both focused and incidental learning.

"Measuring up" to ethical standards in service delivery to college students on the Autism Spectrum: A practical application of Powell's model for ethical practices in clinical phonetics and linguistics.

This paper examined an interdisciplinary college-based support programme, the Communication Coaching Program (CCP), designed for students diagnosed on the autism spectrum in light of six ethical constructs described by Powell. Collecting data to monitor the successes and ongoing needs of individual participants in the programme is of vital importance, of course, but only addresses a portion of the efficacy question. In addition, the authors, who co-direct the programme and represent different professional expertise and perspectives, recognize the importance of determining whether their evolving intervention model has also been successful in meeting the ethical standards of their respective professions. Careful review of the 4 years of the CCP's operation in terms of ethical constructs has yielded evidence that the CCP, although based on sound principles of theory and scholarship, should be further individualized to meet the particular needs of participants diagnosed with deficits in social communication and executive functioning skills.
