RESUMEN
Incorporation of melanoma prevention behaviors into daily lifestyles is difficult. Data suggest that high school educational programs on skin cancer prevention can be successful and should incorporate evidence-based teaching and learning strategies to achieve greatest impact. The goal of this systematic review is to describe evidence-based educational practices for a high-school melanoma curriculum through a comprehensive review of the literature. Ovid MEDLINE, Embase, CINAHL, and PyscINFO were searched in June 2020 for all original articles published between June 18, 1946 and June 17, 2020. All studies that used an educational curriculum to promote sun safety, skin exams, and early detection to high school students were included. A total of 25 studies with 22,683 adolescent participants were analyzed. Sixteen studies showed a significant increase in knowledge, twenty-one studies showed changes in behavior, and fifteen studies showed significant changes in attitudes. Limitations of this review include the heterogeneity of implementation and outcome reporting of educational curricula. These findings support incorporating active learning strategies as key aspects of creating an effective curriculum aimed at the prevention and early detection of melanoma.

OBJECTIVE: The aim of the study was to determine whether employment or insurance status is associated with the presence and number of Waddell signs. DESIGN: In this cross-sectional study, adult low back pain patients were seen at a tertiary academic center for thoracic or lumbar back pain, due to a degenerative condition. Frequency data were compared with contingency table analysis, including χ2 and logistic regression. RESULTS: Of 462 patients, 26% had any Waddell signs and 10% had clinically significant Waddell signs. Nonemployed patients had a higher prevalence of Waddell signs than employed and retired patients (P = 0.0004 and P = 0.001, respectively). Subgroups of Medicaid participants as well as patients with secondary gain issues, including worker's compensation and motor vehicle accident, had a higher prevalence of 1+ Waddell signs than patients of other insurances (P < 0.0001 and P = 0.01, respectively). Medicaid participants had a higher prevalence of 3+ Waddell signs than other insurances (P = 0.002). CONCLUSIONS: The presence of Waddell signs is associated with employment and insurance status. This suggests that social factors may affect patients' perceptions of their thoracic or low back pain. Clinicians aware of these factors can provide individualized care to their patients prone to poor outcomes.

BACKGROUND: Pyoderma gangrenosum (PG) is a chronic, ulcerative neutrophilic dermatosis. PG presents a diagnostic challenge, largely due to the many mimicking diseases, the lack of confirmatory laboratory or biological markers, and the absence of widely accepted diagnostic criteria. In particular, PG is often mistaken for necrotizing soft tissue infections (NSTI). METHODS: We reviewed four major textbooks each in general surgery, plastic surgery, trauma surgery, vascular surgery, emergency medicine, and dermatology. We also performed a search of review articles addressing NSTI and necrotizing fasciitis (NF). RESULTS: Ten out of the 20 non-dermatology textbooks did not list PG anywhere, and only two listed a differential diagnosis for PG. None of the non-dermatology textbooks indicated PG in the NSTI differential diagnosis, while three of the dermatology textbooks included PG in the NSTI differential diagnosis. PG was listed in all of the dermatology textbooks. Only one of the NSTI and NF articles mentioned PG in the differential diagnosis. CONCLUSIONS: There is an underrepresentation in major textbooks of surgery and emergency medicine and in NSTI and NF review articles when it comes to diagnosing PG. This might be leading to trainees and advanced providers in these fields being uninstructed on PG, and likely contributes to PG misdiagnosis and mismanagement. We recommend PG be included in the differential diagnosis of chronic ulcers and NSTI in non-dermatology textbooks. We also suggest adding identification and diagnosis of inflammatory mimickers of NSTI (e.g. PG) in teaching modules in surgical and emergency specialties to address this knowledge gap.

Pyoderma gangrenosum (PG) is an inflammatory condition characterized by chronic cutaneous ulcerations. There are three proposed PG diagnostic frameworks (Su, PARACELSUS, Delphi); however, they lack consensus, and their performance has not yet been validated in a well-defined cohort of patients with PG. In this cross-sectional retrospective cohort study, we sought to evaluate and compare the concordance of these diagnostic frameworks within a single-institution cohort of patients with PG. There were 47 patients from an initial 76 identified by International Classification of Diseases-9 and/or International Classification of Diseases-10 codes, where two PG experts agreed in their diagnosis of PG on the basis of clinical descriptions, photographs, and pathology. This group was the PG cohort by which we evaluated the performance and concordance of the diagnostic frameworks. The PARACELSUS score identified the highest proportion of patients with PG (89% [42 of 47 patients]), followed by Delphi and Su criteria, each at 74% (35 of 47 patients). Assessment of multirater agreement found that the three criteria agreed in their diagnoses for 72% of the patients (95% confidence interval = 60-85%); chance-adjusted agreement was determined to be 0.44 (95% confidence = 0.16-0.68, Fleiss' kappa). Future research should seek to refine these diagnostic frameworks and identify targeted methods of testing to reduce rates of PG misdiagnosis and patient misclassification in clinical trials.

INTRODUCTION: Pyoderma gangrenosum (PG) is a rare, ulcerating neutrophilic dermatosis often associated with inflammatory bowel disease, rheumatoid arthritis, and myeloproliferative disorders. The classic description of PG includes irregularly shaped ulcers with undermined edges with a gun-metal gray or violaceous hue. The etiology remains unclear but appears to be related to genetically predisposed dysregulation of the innate immune system. Diagnosis of PG can be difficult as it can present with symptoms similar to cutaneous infections including erythema, edema, ulceration, fever and leukocytosis. Surgical procedures are generally contraindicated in patients with PG due to the risk of pathergy, excessive cutaneous injury, or ulceration in response to trauma. CASE REPORT: The authors report the development of PG with the initiation of chemotherapy in a 46-year-old woman with breast cancer. The patient had a complicated clinical course after multiple surgical debridements due to an initial misdiagnosis of necrotizing fasciitis. The patient's rapid onset of post-procedural ulceration was consistent with the pathergy of PG. The diagnosis of PG was confirmed by skin biopsy, which revealed a diffuse neutrophilic infiltrate, and with the patient's negative cultures and response to steroids. The patient was treated with perioperative prednisone and intravenous immunoglobulin prior to a mastectomy for her breast cancer. The surgery was not complicated by pathergy. CONCLUSIONS: This unique case highlights the challenging aspects in the medical and perioperative management of active PG in a patient with breast cancer.

Pyoderma gangrenosum (PG) classically presents with an acute inflammatory stage, characterized by rapid evolution of painful ulcerations. The pathergy associated with PG lesions complicates disease management. Although PG is commonly treated with immunosuppression, some patients have refractory noninflammatory ulcers. In this subpopulation, there are case reports of successful surgical treatment. However, there is no consensus on optimal perioperative treatment for patients with PG undergoing surgery of any kind, PG related or otherwise. Therefore, we conducted a comprehensive literature review describing perioperative management practices and risk factors that may predict response to surgical intervention. We identified 126 cases of surgical intervention in patients with active PG; among these, only 16.7% experienced postoperative disease progression. No perioperative treatments or clinical risk factors were identified as statistically significant predictors of disease recurrence. Although limited by case series design and publication bias, this study is a valuable means of hypothesis generation for this rare condition.

Background: Pyoderma gangrenosum (PG) is a neutrophilic disorder which classically presents as chronic, painful ulcers on the lower extremities. There is evidence supporting a potential role for intravenous immunoglobulin (IVIG) as adjuvant therapy for treatment-resistant cases; however, it is unclear which patients will most benefit from this modality of treatment - an especially important consideration given the cost per infusion ($5000-$10,000). Thus, we sought to identify the clinical characteristics of patients with refractory PG lesions who demonstrated complete healing when IVIG was incorporated into the therapeutic plan.Methods: We performed a literature search of PubMed/MEDLINE and Embase using the keywords 'pyoderma gangrenosum' and 'IVIG'. We also added four institutional cases. Descriptive statistics were used to analyze the data. Significance was set at p < .05.Results: We discovered a total of 45 cases. Twenty-three patients with treatment-resistant PG had complete healing, 22 had partial or unhealed PG ulcers. Patients with one ulcer were 4.1 (95% CI: 1.1-18.5) times more likely to achieve complete healing than patients with more than one ulcer, when IVIG was added (p = .041).Conclusion: There is increased efficacy of IVIG as a treatment for patients with a solitary treatment-resistant PG lesion compared to patients with multiple refractory lesions.

Pyoderma gangrenosum (PG) is a rare, ulcerative inflammatory skin disease that most commonly occurs in patients with inflammatory bowel disease, rheumatologic diseases, or hematologic diseases. Successful treatment of PG often requires immunosuppression and appropriate wound care. Systemic corticosteroids and cyclosporine are the first-line treatments for PG. However, chronic use of these systemic agents places patients at risk for developing significant side effects, including hyperglycemia, osteoporosis, hypertension, and weight gain. Furthermore, when treating small or superficial PG ulcers, the use of local agents as monotherapies or adjuvant treatments can be ideal to control inflammation and promote healing without placing the patient at risk for many severe side effects that can be seen with long-term use of systemic agents. This literature review assesses all available local therapies in order to summarize the use and reported efficaciousness of the broad range of local treatments available for PG.

Reports detailing the acute formation of aluminum granulomas, which can cause persistent, intensely pruritic nodules secondary to the administration of aluminum-containing vaccines, are infrequently described in medical literature. To our knowledge, this is the first report describing the development of an aluminum granuloma causing a persistent, pruritic nodule at the injection site following the administration of the DTaP-IPV vaccine. We present the case of a 6-year-old girl who developed a severely pruritic subcutaneous nodule on her anterior right thigh at the injection site three weeks after the administration of the aluminum-containing DTaP-IPV (Kinrix) vaccine. The nodule was eventually excised 14 months after its initial appearance, after which her symptoms resolved. Histologic inspection demonstrated a dense, deep dermal and subcutaneous nodular mixed infiltrate of lymphocytes, histiocytes, and eosinophils, with germinal center formation. The bluish, amphophilic granular cytoplasm found in most of the histiocytes is a characteristic feature of "aluminum granulomas." This adverse reaction should be considered in any patient presenting with similar findings in the weeks following a DTaP-IPV vaccination or other aluminum-containing vaccines. Furthermore, the self-limiting tendency of these nodules should not preclude affected patients from any future vaccinations, though vaccines without aluminum should be preferentially selected when possible.

Importance: Pyoderma gangrenosum and necrotizing Sweet syndrome are diagnostically challenging variants of neutrophilic dermatosis that can clinically mimic the cutaneous and systemic features of necrotizing fasciitis. Improved characterization of these rare variants is needed, as improper diagnosis may lead to inappropriate or delayed treatment and the potential for morbidity. Objective: To determine the characteristics of necrotizing neutrophilic dermatosis to improve diagnostic accuracy and distinguish from infection. Design, Setting, and Participants: A case series of patients with necrotizing neutrophilic dermatosis treated at 3 academic hospitals (University of California San Francisco, Oregon Health and Science University, and University of Minnesota) from January 1, 2015, to December 31, 2017, was performed along with a literature review of related articles published between January 1, 1980, and December 31, 2017. Data were obtained from medical records as well as Medline and Embase databases. All patients had signs resembling necrotizing infection and had a final diagnosis of pyoderma gangrenosum with systemic features or necrotizing Sweet syndrome. Patients were excluded if a diagnosis other than neutrophilic dermatosis was made, if key clinical information was missing, and if reported in a non-English language. Main Outcomes and Measures: Description of key characteristics of necrotizing neutrophilic dermatosis. Results: Overall, 54 patients with necrotizing neutrophilic dermatosis were included, of which 40 had pyoderma gangrenosum with systemic features and 14 had necrotizing Sweet syndrome. Of the 54 patients, 29 (54%) were male and 25 (46%) were female, with a mean (SD) age of 51 (19) years. Skin lesions commonly occurred on the lower (19 [35%]) and upper (13 [24%]) extremities and developed after a surgical procedure (22 [41%]) or skin trauma (10 [19%]). Shock was reported in 14 patients (26%), and leukemoid reaction was seen in 15 patients (28%). Of the patients with necrotizing neutrophilic dermatosis, 51 (94%) were initially misdiagnosed as necrotizing fasciitis and subsequently received inappropriate treatment. Debridement was performed in 42 patients (78%), with a mean (SD) of 2 (2 [range, 1-12]) debridements per patient. Four amputations (7%) were performed. Forty-nine patients (91%) received antibiotics when necrotizing neutrophilic dermatosis was misdiagnosed as an infection, and 50 patients (93%) received systemic corticosteroids; all patients responded to immunosuppressants. Conclusions and Relevance: A complex spectrum of clinical findings of pyoderma gangrenosum and Sweet syndrome with prominent systemic inflammation exists that defines a new subset of neutrophilic dermatoses, termed necrotizing neutrophilic dermatoses; recognizing the difference between this variant and severe infection may prevent unnecessary surgical procedures and prolonged disease morbidity associated with a misdiagnosis and may expedite appropriate medical management.
