[Effectiveness of interventions to help mitigate the influence of social networks on anorexia and bulimia nervosa: a systematic review].

BACKGROUND: The study aim to analyze the impact of interventions to help mitigate the influence of social networks on anorexia and bulimia nervosa. METHODOLOGY: A systematic review was conducted using PubMed, Scopus, PsycINFO and Web of Science. The inclusion criteria were: randomized clinical trials, published between 2013 and 2023 with a score = 5 points on the Van Tulder methodological quality scale. RESULTS: Eight studies were selected, most carried out in secondary education centers or universities; one was online. The study sample consisted of 5,084 participants mainly young women and adolescents with an average age between 12 and 32 years. As for the social networks, some studies described their impact at a general level, while others focused on Instagram, Facebook, Tik-Tok, Twitter, and Snapchat. A positive correlation was found between the exposure to unrealistic beauty ideals found in social networks with greater concern and dissatisfaction with body image. All studies used instruments to assess the effectiveness of the interventions. The interventions helped reduce the influence of the media and social networks, improve self-perception and self-esteem assessments, reduce anxiety levels and internalization of the thin beauty ideal, reduce dietary restrictions, and make use of social networks differently. CONCLUSIONS: Longer-lasting interventions can improve body satisfaction (one year) and depressive symptoms (six months), especially in women. Interventions should include attention to self-criticism, self-perception, self-esteem, body image, nutritional management, and media literacy skills.

Pilomatrixoma of the Forearm in an Elderly Male.

Pilomatrixoma or pilomatricoma is a benign adnexal neoplasm originating from the hair matrix, the inner sheath of the hair follicle, and the hair cortex. Although it is considered rare in adults, numerous cases have been documented in the literature. We present a case of an elderly male who sought consultation due to a newly appearing nodular lesion on his left forearm. Several benign and malignant entities were included in the original differential diagnosis. High-frequency ultrasonographic features suggested a cystic neoplasm with calcification and mild intralesional vascularity. Ultimately, histopathological examination confirmed the diagnosis of pilomatricoma. In this study, our aim is to review the importance of the available diagnostic tools, such as dermoscopy, and the emerging utility of cutaneous high-frequency ultrasonography. Some rarer pathological variants are also discussed, including perforating, anetodermic, bullous and pigmented pilomatricoma. We hope that exposure to these clinical, dermoscopic, ultrasonographic, and histopathological images will encourage clinicians to consider pilomatricoma in their differential diagnosis when approaching nodular lesions, regardless of location and patient's age.

Principales tipos de quistes en dermatopatología: parte 1 / Main Types of Cysts in Dermatopathology: Part 1

Las estructuras quísticas son uno de los hallazgos más frecuentes en dermatopatología. Se trata de tumores quísticos y de pseudoquistes por acumulación de ciertas sustancias, por ejemplo, mucina. En una serie de dos artículos (de los cuales este es el primero) hemos revisado los principales tipos de quistes y pseudoquistes que pueden verse en la biopsia cutánea, examinando sus aspectos histopatológicos y los principales diagnósticos diferenciales. En esta primera parte, se abordan los quistes infundibulares, dermoides, vellosos eruptivos, foliculares pigmentados, pilonidales, tricolemales, de milium, híbridos y broncogénicos, así como el esteatocistoma, el hidrocistoma y los comedones.

Approach to the so-called "Invisible Dermatosis": When Subtle Histopathological Findings Guide Diagnosis.

ABSTRACT: Invisible dermatosis is a concept that can be applied either to clinical or histopathological findings. We will focus on the dermatopathological aspect of this invisible dermatosis that can be seen as dermatosis with subtle histopathological findings that are mandatory to known to stablish the diagnosis. With a proper approach facing in depth the different skin layers from stratum corneum to subcutaneous tissue combined with some especial stains, special investigations and mostly a proper clinicopathological correlation, the problem of missing out a diagnosis can be decreased. We will review the general aspects for diagnosis and the peculiar findings of an in-depth review of them because it is important to note that minor changes on a skin biopsy do not mean it is disease free. We will review classic clues, we will add some new useful ones, and we will also provide a guide on the special stains helpful, such as periodic acid-Schiff when facing fungi, orcein-Giemsa and van Gieson when altered elastic fibers are suspected, or Pearl and Masson Fontana when an altered skin pigmentation is suspected.

Efficacy of gel containing organic extra virgin olive oil for peristomal skin hygiene: A pilot randomised controlled trial.

AIM: To assess the efficacy and safety of the application, during stoma hygiene, of a pH-neutral gel containing organic EVOO (oEVOO) for the maintenance of peristomal skin integrity. METHOD: Patients with a colostomy or ileostomy were enrolled in a pilot randomized controlled trial and assigned treatment with a pH-neutral gel made from natural products including oEVOO or usual stoma hygiene gel. The primary outcome was three domains of abnormal peristomal skin: Discolouration, Erosion and Tissue overgrowth. Secondary outcomes that were evaluated included skin moisture; oiliness; skin elasticity; water-oil balance; patients' perceptions; difficulty inserting and removing the pouching system; pain, any other chemical, infectious, mechanical, or immunological complications of concern. The intervention lasted 8 weeks. RESULTS: Twenty-one patients were recruited for the trial and randomly assigned to either the experimental group (n = 12) or the control group (n = 9). The groups did not differ significantly in terms of patient characteristics. No significant differences between groups were identified either at baseline (p = 0.203) or at the end of the intervention (p = 0.397). In the experimental group, domains of abnormal peristomal skin improved after the intervention. The difference observed before and after the intervention was statistically significant (p = 0.031). CONCLUSION: The use of a gel containing oEVOO has shown similar levels of efficacy and safety to other gels commonly used for peristomal skin hygiene. It is also relevant to highlight that a significant improvement in skin condition was observed in the experimental group before and after the intervention.

Assessment of Health Indicators in Individuals with Intestinal Stoma using the Nursing Outcomes Classification: A Cross-Sectional Study.

Aim: To determine nursing outcomes in individuals with intestinal stoma and the relationships between them and sociodemographic and clinical variables. Design: Cross-sectional study performed with 102 subjects at the General Surgery Unit of a first-level hospital. Methods: Data on the presence of nursing outcomes were collected using the Nursing Outcomes Classification. Data on sociodemographic and clinical variables were also collected. Univariate and bivariate data analyses were performed. Results: Outcomes related to participation in making health decisions and knowledge of ostomy care were assessed across the study sample. Period of care (post-operative and follow-up) was the most common significant variable (p < 0.05) among the outcomes. The outcome scores ranged from 2 to 3, indicating a moderate level of impairment in the physical, psychological, and social spheres of these patients. The scores in the indicators on Participation in making health decisions and Knowledge of stoma care improved in the period of continuity of care compared to the postoperative period, being this difference statistically significant (p < 0.001). Conclusions: The care plan for individuals with intestinal stoma needs to include indicators measuring patient participation in making decisions related to their condition, as well as indicators related to their knowledge and self-care of their stoma. Relevance to clinical practice: This study aims to determine the nursing outcomes in individuals with intestinal stoma and the relationships between them and sociodemographic and clinical variables. It provides the opportunity to plan achievable objectives with patients using a system of indicators that facilitate their assessment and monitoring.

Evaluation of interventions in people with digestive stoma through the Nursing Interventions Classification.

PURPOSE: To determine which nursing interventions are used in individuals with a digestive stoma and the relationships between nursing interventions used and sociodemographic and clinical variables. METHODS: The present study is an observational, cross-sectional, descriptive. Data from 102 individuals in the general surgery unit of a first-level hospital (University Hospital Complex of Granada, Spain) were analyzed. Data on the use of nursing interventions and sociodemographic and clinical variables were collected. Univariate, bivariate, and multivariate data analyses were conducted. FINDINGS: Interventions: Decision-Making Support (5250) and Ostomy Care (0480) were the most prevalent interventions in the sample. The period of care (postoperative and follow-up) was the most common significant variable (p < 0.05) among the interventions observed. Anxiety Reduction (5820), Nutritional Counseling (5246), Self-Esteem Enhancement (5400), and Body Image Enhancement (5220) were also relevant findings. CONCLUSIONS: The present study contributes to determining which nursing interventions are used in individuals with a digestive stoma. IMPLICATIONS FOR NURSING PRACTICE: This study could be useful in planning nursing interventions in individuals with a digestive stoma.

Histopathologic Spectrum of Findings Associated With Tattoos: Multicenter Study Series of 230 Cases.

IMPORTANCE: Reactions to tattoo may simulate common dermatosis or skin neoplasms. Histopathology allows diagnosis and helps determining the level and degree of inflammation associated, consequently orientating treatment. OBJECTIVE: To describe the histological features found in biopsies of cutaneous reactions to tattoo. DESIGN: This study was designed as a multicenter case series. SETTING: All consecutive histopathological samples of tattoos referred from 1992 to 2019 to the Hospital General de Catalunya, Hospital Germans Trias i Pujol, and a private practice, all in Barcelona, Spain, and from the Kempf und Pfaltz Histologische Diagnostik in Zurich, Switzerland were retrieved from the files. PARTICIPANTS AND EXPOSURE: The inclusion criteria were all cosmetic/permanent makeup, artistic/professional, and traumatic tattoos associated with either inflammatory reactions alone and/or with tumors and/or infections. Exclusion criteria were cases without any associated pathologic finding in the place of the ink, amalgam tattoos, and medical or temporary tattoos. MAIN OUTCOMES AND MEASURES: In all patients, clinical features (age, sex, location, tattoo color, and presentation) were recorded. Histological features evaluated included ink color, associated tumors or infections, and inflammatory reaction pattern. Inflammation was graded in low to moderate or severe. RESULTS: From 477 biopsies diagnosed as tattoos, 230 cases from 226 patients met the inclusion criteria. Samples corresponded to 107 male and 120 female subjects and 3 of unknown gender. Median age was 39 years (ranging from 9 to 84 years). Fifty-three samples were referred from centers in Spain and 177 from the center in Switzerland. The series was analyzed in 2 parts: tattoos associated only with inflammatory reactions (117/230) and tattoos associated with tumors or infections (113/230). The most common form of inflammatory pattern associated with tattoo was the fibrosing reaction (79/117, 68%), followed by granulomatous reaction (56/117, 48%), lichenoid reaction (33/117, 28%), epithelial hyperplasia (28/117, 24%), pseudolymphoma (27/117, 23%) and spongiotic reaction (27/117, 23%). Combined features of 2 or more types of inflammatory patterns were seen in 64% cases. CONCLUSIONS AND RELEVANCE: Our series confirms that cutaneous reactions to tattoos are polymorphous. Inflammation tends to present with combined patterns. Infections are tending to decline, and pathologic findings are not specific to ink color or clinical features.
