RESUMEN
OBJECTIVE: To investigate the effectiveness of community-based mental health interventions by professionally trained, lay counsellors in low- and middle-income countries. METHODS: We searched PubMed®, Cochrane Central Register of Controlled Trials, PROSPERO and EBSCO databases and professional section publications of the United States National Center for PTSD for randomized controlled trials of mental health interventions by professionally trained, lay counsellors in low- and middle-income countries published between 2000 and 2019. Studies of interventions by professional mental health workers, medical professionals or community health workers were excluded because there are shortages of these personnel in the study countries. Additional data were obtained from study authors. The primary outcomes were measures of post-traumatic stress disorder, depression, anxiety and alcohol use. To estimate effect size, we used a random-effects meta-analysis model. FINDINGS: We identified 1072 studies, of which 19 (involving 20 trials and 5612 participants in total) met the inclusion criteria. Hedges' g for the aggregate effect size of the interventions by professionally trained, lay counsellors compared with mostly either no intervention or usual care was -0.616 (95% confidence interval: -0.866 to -0.366). This result indicates a significant, medium-sized effect. There was no evidence of publication bias or any other form of bias across the studies and there were no extreme outliers among the study results. CONCLUSION: The use of professionally trained, lay counsellors to provide mental health interventions in low- and middle-income countries was associated with significant improvements in mental health symptoms across a range of settings.

BACKGROUND: Actinic keratoses (AK) are rough scaly patches that arise on chronically ultraviolet-exposed skin and can progress to keratinocyte carcinoma. Treatment options for AK include topical medications, photodynamic therapy, cryosurgery, and laser ablation. OBJECTIVE: This executive summary provides a synopsis of the 18 evidence-based recommendations for the treatment of AK detailed in the Guidelines of Care for the Management of Actinic Keratosis. METHODS: A multidisciplinary workgroup conducted a systematic review to address 5 clinical questions on the management of AKs and applied the Grading of Recommendations Assessment, Development and Evaluation approach for assessing the certainty of the evidence and formulating and grading clinical recommendations. Graded recommendations were voted on to achieve consensus. RESULTS: Analysis of the evidence resulted in 18 recommendations, suggesting there are several effective treatments available for AK. LIMITATIONS: The analysis informing the recommendations was based on the best available evidence at the time it was conducted. The results of future studies may necessitate a revision of current recommendations. CONCLUSIONS: Strong recommendations are presented for using ultraviolet protection, topical imiquimod, topical 5-fluorouracil, and cryosurgery. Conditional recommendations are presented for the use of photodynamic therapy and diclofenac for the treatment of AK, both individually and as part of combination therapy regimens.

BACKGROUND: Actinic keratoses (AK) are rough scaly patches that arise on chronically ultraviolet-exposed skin and can progress to keratinocyte carcinoma. OBJECTIVE: This analysis examined the literature related to the management of AK to provide evidence-based recommendations for treatment. Grading, histologic classification, natural history, risk of progression, and dermatologic surveillance of AKs are also discussed. METHODS: A multidisciplinary Work Group conducted a systematic review to address 5 clinical questions on the management of AKs and applied the Grading of Recommendations, Assessment, Development, and Evaluation approach for assessing the certainty of the evidence and formulating and grading clinical recommendations. Graded recommendations were voted on to achieve consensus. RESULTS: Analysis of the evidence resulted in 18 recommendations. LIMITATIONS: This analysis is based on the best available evidence at the time it was conducted. The pragmatic decision to limit the literature review to English language randomized trials may have excluded data published in other languages or limited identification of relevant long-term follow-up data. CONCLUSIONS: Strong recommendations are made for using ultraviolet protection, topical imiquimod, topical 5-fluorouracil, and cryosurgery. Conditional recommendations are made for the use of photodynamic therapy and diclofenac for the treatment of AK, both individually and as part of combination therapy regimens.

BACKGROUND: Mass violence, atrocities, and political upheavals have affected the prosperity and psychological health of the people of Iraq. Those living in the Garmian region of the Kurdistan Region of Iraq are among those most affected. While there is an urgent need for mental health interventions in this region, mental health resources are scarce, and only a small percentage of the population in need receive mental health care. Despite the high burden of mental illness, and the general demand by the community and local authorities for social and psychological services, effective validated cost-effective interventions tailored to address the cultural and social problems are scarce. This retrospective case series study, which is based on the lead author's experiences in the Garmian region, aims to describe the results of using two mental health interventions, cognitive behavioral therapy and thought field therapy. METHODS AND FINDINGS: The files of 31 clients that met criteria of the study were selected using purposive sampling. The results showed that, of the 13 clients who received Cognitive Behavioral Therapy, one improved and others showed either no change in symptoms, deterioration of symptoms, or dropped out of treatment. All 11 clients who received only Thought Field Therapy, showed improvement in their symptoms. Seven clients who received Cognitive Behavioral Therapy and showed no improvement received Thought Field Therapy, and showed improvement finally. While the results of preliminary experience with Thought Field Therapy in the Garmian community is encouraging, conducting randomized controlled trials with follow-ups, and comparing Thought Field Therapy with other therapeutic approaches is needed to substantiate these findings. CONCLUSION: We found that Thought Field Therapy had positive results in reducing anxiety disorders and trauma related symptoms, as compared to Cognitive Behavioral Therapy.

To characterize the clinical features, associated disorders, and treatment of necrobiotic xanthogranuloma (NXG), a rare non-Langerhans cell histiocytosis, we conducted a retrospective review of pathologically confirmed NXG at Mayo Clinic Arizona from 1987 to June 2017. Data on clinical findings, laboratory findings, associated disorders, therapy, and response to therapy were extracted. Nineteen patients were identified. Mean age was 54 years (range, 17-84) with equal gender distribution. Median follow-up was 5.5 years (range, 1-18). Most patients had a detectable monoclonal protein (84%), and IgG kappa constituted 58%. The most common cutaneous lesions involved the periorbital region (53%). The majority of patients had extracutaneous manifestations, most commonly affecting the liver (32%) and the sinuses (21%). Hematologic malignancies were diagnosed in 26% of patients and included Hodgkin lymphoma, chronic lymphocytic leukemia (CLL), smoldering myeloma, and multiple myeloma. The most common treatment was chlorambucil with or without systemic corticosteroids. Response was seen in most patients (95%), and most patients received 1-3 lines of therapy (74%). NXG is a reactive histiocytic disorder that commonly involves multiple organ systems and requires a high degree of clinical suspicion for accurate diagnosis. Treatment decisions should be based on coexisting conditions and pattern of disease involvement.

The appropriate use criteria process synthesizes evidence-based medicine, clinical practice experience, and expert judgment. The American Academy of Dermatology in collaboration with the American College of Mohs Surgery, the American Society for Dermatologic Surgery Association, and the American Society for Mohs Surgery has developed appropriate use criteria for 270 scenarios for which Mohs micrographic surgery (MMS) is frequently considered based on tumor and patient characteristics. This document reflects the rating of appropriateness of MMS for each of these clinical scenarios by a ratings panel in a process based on the appropriateness method developed by the RAND Corp (Santa Monica, CA)/University of California-Los Angeles (RAND/UCLA). At the conclusion of the rating process, consensus was reached for all 270 (100%) scenarios by the Ratings Panel, with 200 (74.07%) deemed as appropriate, 24 (8.89%) as uncertain, and 46 (17.04%) as inappropriate. For the 69 basal cell carcinoma scenarios, 53 were deemed appropriate, 6 uncertain, and 10 inappropriate. For the 143 squamous cell carcinoma scenarios, 102 were deemed appropriate, 7 uncertain, and 34 inappropriate. For the 12 lentigo maligna and melanoma in situ scenarios, 10 were deemed appropriate, 2 uncertain, and 0 inappropriate. For the 46 rare cutaneous malignancies scenarios, 35 were deemed appropriate, 9 uncertain, and 2 inappropriate. These appropriate use criteria have the potential to impact health care delivery, reimbursement policy, and physician decision making on patient selection for MMS, and aim to optimize the use of MMS for scenarios in which the expected clinical benefit is anticipated to be the greatest. In addition, recognition of those scenarios rated as uncertain facilitates an understanding of areas that would benefit from further research. Each clinical scenario identified in this document is crafted for the average patient and not the exception. Thus, the ultimate decision regarding the appropriateness of MMS should be determined by the expertise and clinical experience of the physician.

BACKGROUND: Do patch test results vary from one part of the USA to another? Few reports directly compare the results of patch testing across centers within the USA. OBJECTIVES: Our objective was to compare results of patch testing from three geographically disparate Mayo Clinic sites in the USA to ascertain whether there are any differences in allergic patch test rates. METHODS: We retrospectively reviewed patch test results for patients tested with a standard allergen series using our enterprise-wide protocol for patch testing. We compared data collected from January 1, 2001, through to December 31, 2007, from our practice sites in the Midwest, Southwest, and Southeast regions of the USA. RESULTS: In total, 5063 patients underwent patch testing. The mean (standard deviation) number of allergens tested per patient was 70.3 (3.8) (range: 10-87; interquartile range: 68-73). Analyses were conducted separately for 72 allergens with positive reactions from at least 20 patients. Risk-adjusted positive reaction rates (RAPRRs) for 44 allergens differed significantly (P<0.05) among the geographic sites; RAPRRs differed significantly across all three sites for 11 allergens and between two of the three sites for 33 allergens. CONCLUSIONS: Allergic patch test rates differed among our three practice sites for many allergens. It is likely that many factors contributed to these observed differences, including variations in the population undergoing patch testing, variations in allergen exposure, and variations in climate.

BACKGROUND: The standard allergen series used in patch testing contains metals that most commonly cause allergic contact dermatitis, but testing with additional metal allergens is warranted for select patients. OBJECTIVE: To report our experience with patch testing of metals. METHODS: We retrospectively analyzed outcomes of 1,112 patients suspected of having metal allergies. Patients were seen from January 1, 2000, through December 31, 2009. Patch testing was performed with 42 metal preparations (6 in the standard series, 36 in the metal series). RESULTS: Patch testing most commonly was performed for patients with oral disease (almost half the patients), hand dermatitis, generalized dermatitis, and dermatitis affecting the lips, legs, arms, trunk, or face. At least one positive reaction was reported for 633 patients (57%). Metals with the highest allergic patch-test reaction rates were nickel, gold, manganese, palladium, cobalt, Ticonium, mercury, beryllium, chromium, and silver. Metals causing no allergic patch-test reactions were titanium, Vitallium, and aluminum powder. Metals with extremely low rates of allergic patch-test reactions included zinc, ferric chloride, and tin. Reaction rates varied depending on metal salt, concentration, and timing of readings. CONCLUSION: Many metals not in the standard series were associated with allergic patch-test reactions. The many questions raised by these findings, concerning patch testing with individual metals, will be the subject of future studies.

Thought Field Therapy (TFT), which utilizes the self-tapping of specific acupuncture points while recalling a traumatic event or cue, was applied with 50 orphaned adolescents who had been suffering with symptoms of PTSD since the Rwandan genocide 12 years earlier. Following a single TFT session, scores on a PTSD checklist completed by caretakers and on a self-rated PTSD checklist had significantly decreased (p < .0001 on both measures). The number of participants exceeding the PTSD cutoffs decreased from 100% to 6% on the caregiver ratings and from 72% to 18% on the self-ratings. The findings were corroborated by informal interviews with the adolescents and the caregivers, which indicated dramatic reductions of PTSD symptoms such as flashbacks, nightmares, bedwetting, depression, isolation, difficulty concentrating, jumpiness, and aggression. Following the study, the use of TFT on a self-applied and peer-utilized basis became part of the culture at the orphanage, and on one-year follow-up the initial improvements had been maintained as shown on both checklists.

BACKGROUND: Vitamin E, of which the most biologically active form is alpha-tocopherol, has become widely known for its antioxidant effects. It has been ingested or applied topically for purported anti-aging effects and for cosmetic enhancement. OBJECTIVE: To determine whether the incidence of allergic contact dermatitis from vitamin E has increased in recent years. METHODS: With the approval of the Mayo Clinic institutional review board, we retrospectively analyzed patch-test data from patients tested from June 1987 through December 2007. RESULTS: A total of 2,950 patients were patch-tested during this period, and 18 patients (0.61%) had positive reactions to alpha-tocopherol; 6 (0.53%) of 1,136 patients tested from June 1987 through December 1997 had positive results, and 12 (0.66%) of 1,814 patients tested from January 1998 through December 2007 had positive results (p = .69). CONCLUSION: Vitamin E appears to be a relatively rare contact allergen in our experience.

BACKGROUND: Both physician-driven and patient-driven factors influence biopsy decisions. We sought to determine the ratio of benign to malignant melanocytic biopsy findings in our general dermatology practice and to characterize the reasons for biopsy. METHODS: A retrospective review of institutional records (1 January to 31 December 2005) was undertaken. RESULTS: We identified 1398 nevi, 147 invasive and in situ melanomas, and two lesions interpreted as atypical melanocytic proliferations. Prior histories of melanoma, atypical nevi, or nonmelanoma skin cancer were common. Patient concerns about changes or symptoms drove about one-third of the biopsies. Physician concerns more commonly drove biopsies in men and older patients (> 60 years). Physician-directed biopsies more commonly yielded atypical nevi, but there was no difference in the likelihood of melanoma. The ratio of removed nevi to melanomas was 9.2 : 1. CONCLUSIONS: Both patient-driven and physician-driven indications lead to skin biopsies. We found no standard method of documentation of dermoscopic evaluation, which prevented us from making definitive conclusions about the role of dermoscopy in this cohort.

BACKGROUND: Photopatch testing is important for diagnosing photoallergic contact dermatitis. Although results of photopatch testing have been presented from many European centers, there have been few reports of the results of photopatch testing in the United States. OBJECTIVE: To review the Mayo Clinic's recent experience with photopatch testing, identify common photoallergens, and compare our current and previous findings. METHODS: We retrospectively reviewed records of patients who underwent photopatch testing at the Mayo Clinic between January 1, 2000, and December 31, 2005 (N = 182). RESULTS: Fifty-four patients (29.7%) had photoallergic contact reactions, and 29 (15.9%) had allergic contact reactions. The most common photoallergens were medications, sunscreen agents, fragrances, and antiseptics. CONCLUSION: Photopatch testing is the technique useful in identifying photoallergens. The series of allergens used must be constantly updated to reflect newly identified and outdated photoallergens. We present a 6-year experience with photopatch testing. Medications, sunscreen agents, fragrances, and antiseptics were the most frequently identified photoallergens.

OBJECTIVE: To present and interpret results of patch testing with the Mayo Clinic standard series over 5 years. DESIGN: Retrospective study. A standardized patch testing technique was used. Data were recorded on a standardized computer program from January 1, 2001, to December 31, 2005, and analyzed. SETTING: Tertiary referral center. PATIENTS: Patients who were referred for patch testing. INTERVENTION: Patch testing with the "standard series," ie, a standard series of allergens used by most clinicians to identify the most common offending allergens in patients with allergic contact dermatitis. MAIN OUTCOME MEASURES: Number of patients patch tested, allergens used over this period, and rates of allergic patch test reactions to allergens. RESULTS: A total of 3854 patients (mean age, 55.1 years; age range, 6.2-99.4 years; 2576 female [66.8%]) were tested. All dermatologists in the department performed patch testing. The mean number of allergens included was 69.3 (range, 6-87). There were 2664 patients with at least 1 positive reaction (69.1%) and 1933 with 2 or more positive reactions (50.2%). Metals, fragrances, topical antibiotics, preservatives, and individual allergens used in hair-care products, topical corticosteroids, glues, plastics, and rubber were still the most common allergen groups associated with allergic patch test reactions. CONCLUSIONS: We describe the structure of the patch testing service at our referral center. Ongoing analysis of our patch test reaction rates allows us to recommend broad, clinically relevant, and up-to-date allergens for testing.

BACKGROUND: Patients diagnosed with melanoma of the foot have been reported to have a poor prognosis. We reviewed our experience at a tertiary-care medical clinic to determine the disease course in patients diagnosed with melanoma of the foot. METHODS: A retrospective review was performed of 38 patients with a diagnosis of primary or locally recurrent melanoma of the foot treated between January, 1988, and July, 2004. The main outcome measures included methods of diagnosis, clinical and histopathologic features, and patterns of recurrence. RESULTS: The mean age at diagnosis was 61 years; most were women (58%) and Caucasian (95%). The average time to diagnosis was 17 months. Initial clinical diagnosis had been considered benign in 12 (32%). The median Breslow thickness was 1.75 mm, T1 lesions were the most common, and acral lentiginous melanoma accounted for 42%. Thirteen patients (34%) had ulcerated lesions. Sentinel lymph node biopsy specimens of 25 patients identified four (16%) with metastatic disease. Surgical complications occurred in 12 patients, usually after skin graft or soft-tissue flap reconstruction. Systemic recurrence developed in six patients, four of whom also had regional recurrence. CONCLUSIONS: Most patients were elderly Caucasian women and most presented with early-stage disease, but diagnosis can be difficult and a subgroup presented with thick melanomas. Reconstructive surgical procedures had a high rate of complications; however, overall functional outcomes were good. Stage of cancer at diagnosis was associated with systemic metastases.

BACKGROUND: Patch testing is a diagnostic tool for the evaluation of patients with suspected allergic contact dermatitis. A standard series of allergens similar to that used by the North American Contact Dermatitis Group (NACDG) is used at Mayo Clinic. OBJECTIVE: Our aim was to report the results of patch testing with a standard series at Mayo Clinic from July 1, 1998, to Dec 31, 2000 and to compare our findings with those of the NACDG during the same period. METHODS: The results of patch testing with the standard series at Mayo Clinic were examined. Positive reaction rates were compared between Mayo Clinic and the NACDG. RESULTS: During the 30-month period, 1324 Mayo Clinic patients were patch tested with a standard series of allergens (mean, 60 allergens), whereas the NACDG standard series during this period included 50 allergens. Overall, 917 patients (69.3%) had at least one positive reaction and 606 patients (45.8%) had two or more positive reactions. The 10 allergens used both by Mayo Clinic and by the NACDG that most frequently caused positive reactions were nickel sulfate hexahydrate, balsam of Peru (Myroxylon pereirae), neomycin sulfate, cobalt chloride, fragrance mix, potassium dichromate (0.25%), thimerosal, bacitracin, formaldehyde, and glutaraldehyde. Statistically significant differences in positive reaction rates (P < .05) were observed for 12 of the 43 allergens common to both Mayo Clinic and the NACDG. CONCLUSION: With large standard patch test series, one can identify commonly encountered and potentially relevant contact allergens.

BACKGROUND: Basal cell carcinoma (BCC) rarely occurs in the axilla. Only 18 cases have been reported in the world literature. OBJECTIVES: To report our institution's 11-year experience with axillary BCC. METHODS: A review of patient charts and biopsy specimens is given. RESULTS: We report 14 patients with 15 axillary BCCs. The average patient age was 65.6. The average lesion size was 10.8 mm. Nine patients had a personal history of skin cancer at sun-exposed sites. One patient had basal cell nevus syndrome. A history of ionizing radiation and severe sunburn involving the axilla was each seen in separate patients. No other predisposing factors for developing BCC were identified, such as immune suppression or a history of other malignancies. Histologic subtypes of all tumors were considered less aggressive, and only one tumor recurred. CONCLUSIONS: Axillary BCC is rare. Factors other than ultraviolet radiation likely contribute to the development of BCC, especially at sun-protected sites. Performing a periodic and complete cutaneous examination that includes sun-protected sites is important, especially in patients who have a history of skin cancer.
