Methotrexate for the treatment of pediatric alopecia areata.

PURPOSE: Alopecia areata is a form of nonscarring hair loss that occurs in pediatric and adult patients, with presentation varying from round or ovoid patches of alopecia to alopecia totalis or universalis. While frustrating for patients, it can also be frustrating for clinicians to treat, as there is no definitive treatment. Dermatologists are very familiar with the use of methotrexate for psoriasis and other inflammatory skin diseases, and this medication is generally well tolerated in children. MATERIALS/METHODS: This study presents a case series reviewing the efficacy of methotrexate in our pediatric patients with alopecia areata, making use of a retrospective chart review design from 2011 to 2016. RESULTS: In this data set, 8/14 subjects (57%) experienced good regrowth with methotrexate, while 3/14 (21%) had a response that could not be assessed due to loss to follow-up or premature discontinuation of the medication. No cases discontinued the medication due to recognized methotrexate side effects. CONCLUSIONS: This review suggests methotrexate is a generally safe and often effective medication in pediatric alopecia areata.

Atopic and Contact Dermatitis of the Vulva.

Pruritus, or itch, is a common vulvar complaint that is often treated empirically as a yeast infection; however, yeast infections are just one of the many conditions that can cause vulvar itch. Ignoring other conditions can prolong pruritus unnecessarily. Atopic dermatitis, irritant contact dermatitis, and allergic contact dermatitis are extremely common noninfectious causes of vulvar itch that are often underdiagnosed by nondermatologists. Identifying these conditions and treating them appropriately can significantly improve a patient's quality of life and appropriately decrease health care expenditures by preventing unnecessary additional referrals or follow-up visits and decreasing pharmaceutical costs.

Community Health Asset Mapping Partnership Engages Hispanic/Latino Health Seekers and Providers.

BACKGROUND: The Hispanic/Latino population in Forsyth County, North Carolina, is growing quickly and experiencing significant disparities in access to care and health outcomes. Assessing community perceptions and utilization of health care resources in order to improve health equity among Hispanics/Latinos at both the county and state levels is critical. METHODS: Our community engagement process was guided by the Community Health Assets Mapping Partnerships (CHAMP) approach, which helps identify gaps in health care availability and areas for immediate action to improve access to and quality of health care. Specifically, we invited and encouraged the Hispanic/Latino population to participate in 4 different workshops conducted in Spanish or English. Participants were identified as either health care providers, defined as anyone who provides health care or a related service, or health care seekers, defined as anyone who utilizes such services. RESULTS: The most commonly cited challenges to access to care were cost of health care, documentation status, lack of public transportation, racism, lack of care, lack of respect, and education/language. These data were utilized to drive continued engagement with the Hispanic community, and action steps were outlined. LIMITATIONS: While participation in the workshops was acceptable, greater representation of health care seekers and community providers is needed. CONCLUSIONS: This process is fundamental to multilevel initiatives under way to develop trust and improve relationships between the Hispanic/Latino community and local health care entities in Forsyth County. Follow-through on recommended action steps will continue to further identify disparities, close gaps in care, and potentially impact local and state policies with regard to improving the health status of the Hispanic/Latino community.

Use of the emergency department for dermatologic care in the United States by ethnic group.

OBJECTIVES: The emergency department (ED) is not the ideal setting for dermatologic care, but may be widely used, especially among disadvantaged ethnic minorities. This study was performed to characterize the role of the ED in providing dermatologic care for each racial and ethnic group in the United States. METHODS: We analyzed visits from the National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey from 1993 to 2010. Settings (office-based, outpatient department or ED), diagnoses and race/ethnicity were assessed to compare usage of the ED across groups. RESULTS: Usage of the ED for dermatologic conditions increased over time (p < 0.0001). EDs were more often used for dermatologic care of black (18.3%) and Hispanic (10.5%) patients than for white patients (5.9%) and were used most in rural or small metropolitan areas. CONCLUSIONS: Providing better insurance, more dermatologists in rural areas and better dermatologic training for family physicians may help improve care for underserved populations and reduce inappropriate use of the ED.

Comorbidity of tinea pedis and onychomycosis and evaluation of risk factors in Latino immigrant poultry processing and other manual laborers.

OBJECTIVES: Latino immigrant workers experience elevated rates of skin disease that result from their working and living conditions. Working in manual occupations exposes workers to a variety of challenges, including occlusive shoes, vigorous physical activity, and wet conditions. These challenges predispose workers to fungal infection. The objectives of this article are to examine the comorbidity of tinea pedis and onychomycosis and to identify possible risk factors among Latino immigrant poultry and nonpoultry workers in western North Carolina. METHODS: Data were obtained from a cross-sectional study conducted between June 2009 and November 2010 in rural western North Carolina among 518 manual Latino immigrant workers to assess their occupational injuries. Participants completed a face-to-face interview and a dermatologic examination. RESULTS: Nearly one-third of the participants (32%) were diagnosed as having onychomycosis and more than one-third (37.8%) were diagnosed as having tinea pedis. There was a greater prevalence of tinea pedis in men than women (71.3% vs 28.7%, respectively). Of the 518 participants, 121 (23.5%) had both conditions. Participants who reported the use of occlusive shoes as "always" or "most of the time" had a higher prevalence of comorbid onychomycosis and tinea pedis than the rest of the group. CONCLUSIONS: Comorbidity of tinea pedis and onychomycosis is common among immigrant Latino men and women who perform manual labor. Further studies confirming the presence and type of dermatophyte should be conducted.

Self-reported skin symptoms and skin-related quality of life among Latino immigrant poultry processing and other manual workers.

BACKGROUND: Manual labor employment occurs in environments with exposures likely to impact skin-related quality of life (SRQOL). OBJECTIVES: The objectives of this paper are to (1) document the dimensions of SRQOL, (2) examine its association with skin symptoms, and (3) identify the predictors of SRQOL in Latino manual workers. METHODS: A population-based survey of 733 Latino manual workers obtained Dermatology Life Quality Index (DLQI) and skin symptoms in the prior year. RESULTS: Two-thirds of workers were employed in production. Skin symptoms in prior year were reported by 23%. Impaired SRQOL was reported by 23%. In multivariate analyses, reduced SRQOL was associated with age, occupation, childhood indigenous language use, and experience of skin symptoms in the prior year. CONCLUSIONS: Despite overall high SRQOL exposures in some immigrant occupational groups produce reduce SRQOL. This rural, immigrant population faces significant obstacles to obtaining dermatological care; efforts are needed to improve their SRQOL.

Dermatologist-diagnosed skin diseases among immigrant Latino poultry processors and other manual workers in North Carolina, USA.

BACKGROUND: Immigrant Latino workers represent an expanding workforce in rural areas of the USA, where their employment is concentrated in occupations such as poultry processing that entail chemical, infectious, and mechanical skin exposures. Occupation-related skin illnesses in this vulnerable population are not well characterized. OBJECTIVES: This study was designed to describe the prevalences of skin diseases among immigrant Latino poultry processors and other manual workers in North Carolina. METHODS: Community-based sampling was used to recruit 742 immigrant Latino workers, 518 of whom underwent a physical examination supervised by a board-certified dermatologist. The presence or absence of skin disease on the face, neck, arms, hands, and feet was recorded. RESULTS: Workers ranged in age from 18 years to 68 years. Slightly over half of the sample were male (52.6%). Poultry workers represented 55.8% of the study sample. Infectious skin diseases were the most common diagnosis, present in 52.3% of workers. Inflammatory skin diseases were present in 28.2% and pigmentary disorders in 21.8% of workers. The most common skin conditions were tinea pedis (37.6%), onychomycosis (31.9%), scars (13.7%), acne (11.8%), and melasma (9.3%). Age, sex, first language, and work as a poultry processor accounted in part for the prevalence of these diseases. CONCLUSIONS: Several skin diseases are highly prevalent in immigrant Latino workers and may relate to work environment. These may impair the quality of life of these workers and predispose them to further illness.

Pachydermodactyly from repetitive motion in poultry processing workers: a report of 2 cases.

BACKGROUND: Pachydermodactyly is a rare, benign, acquired form of digital fibromatosis. The etiology of pachydermodactyly is unknown but is believed to be due to repeated mechanical injury of the skin. We report 2 cases identified in poultry processing workers and review other conditions associated with these cutaneous findings. OBSERVATIONS: The 2 workers in this report were employed as a chicken catcher and a chicken hanger. On examination, both workers had marked lateral thickening of the digits, with associated pain and pruritus. The workers' skin condition developed despite the use of protective gloves, and their symptoms improved when removed from work. However, the swelling due to fibromatosis persisted. CONCLUSIONS: Similar cutaneous findings have been reported in other occupations exposing individuals to repetitive skin trauma, and many patients demonstrating a compulsive habit of hand manipulation. This supports the conclusion that pachydermodactyly in these patients reflects repeated skin trauma. Repetitive mechanical injury in the poultry processing environment can result in considerable compensatory tissue changes. Preventive measures are needed to protect workers.

Top dermatologic conditions in patients of color: an analysis of nationally representative data.

BACKGROUND: Some dermatologic disorders are known to be much more common in patients of color, but the leading dermatologic disorders in patients of color have not yet been described on the basis of nationally representative data. PURPOSE: To determine the leading dermatologic disorders for each major racial and ethnic group in the United States. METHODS: We queried the National Ambulatory Medical Care Survey (NAMCS) for the leading diagnoses in patient visits to U.S. dermatologists from 1993 to 2009. The leading diagnoses were tabulated for each racial and ethnic group, and the top conditions were compared between groups. In a separate analysis, visits for skin conditions regardless of physician specialty were analyzed for leading diagnoses in each racial and ethnic group. RESULTS: The top five diagnoses for African-American patients in dermatology clinics were acne, unspecified dermatitis or eczema, seborrheic dermatitis, atopic dermatitis, and dyschromia. For Asian or Pacific Islander patients, the top five were acne, unspecified dermatitis or eczema, benign neoplasm of skin, psoriasis, and seborrheic keratosis. By contrast, in Caucasian patients, the top five were actinic keratosis, acne, benign neoplasm of skin, unspecified dermatitis or eczema, and nonmelanoma skin cancer. In Hispanic patients of any race, the leading diagnoses were acne, unspecified dermatitis or eczema, psoriasis, benign neoplasm of skin, and viral warts. When the leading dermatologic diagnoses across all physician specialties were assessed, the top diagnoses for African-Americans were unspecified dermatitis or eczema, acne, dermatophytosis of scalp and beard, sebaceous cyst, and cellulitis or abscess; for Asians or Pacific Islanders were unspecified dermatitis or eczema, acne, atopic dermatitis, urticaria, and psoriasis; and for Caucasians were acne, unspecified dermatitis or eczema, actinic keratosis, viral warts, and sebaceous cyst. For Hispanics of any race, they were unspecified dermatitis or eczema, acne, sebaceous cyst, viral warts, and cellulitis or abscess. For a sole diagnosis of a dermatologic condition, only 28.5% of African-Americans' visits and 23.9% of Hispanics' visits were to dermatologists, as compared to 36.7% for Asians and Pacific Islanders and 43.2% for Caucasians. LIMITATIONS: The data are based on numbers of ambulatory care visits rather than numbers of patients. Data on race or ethnicity were not collected for some patients. CONCLUSIONS: Several dermatologic disorders are much more commonly seen in patients of color. Acne and unspecified dermatitis or eczema are in the top five for all major U.S. racial and ethnic groups. There may be an opportunity to improve the care of patients of color by ensuring they have equal access to dermatologists.

Intraoperative imprint cytology for evaluation of sentinel lymph nodes from Merkel cell carcinoma.

Merkel cell carcinoma (MCC) is a rare, aggressive cutaneous malignancy. Intraoperative imprint cytology (IIC) can potentially avoid second operations for completion lymphadenectomy when nodal metastases are found during nodal staging with sentinel lymph node biopsy (SLN). This represents the first series of IIC for MCC we are aware of and our initial experience. Patients with biopsy-proven MCC underwent SLN (at the time of wide excision) using a double indicator technique with 99technetium sulfur colloid and isosulfan blue. SLN were identified and bisected and touch imprints of each half were made. One half was air-dried and stained with Diff-Quick and the other was fixed with 95 per cent alcohol and stained with hematoxylin and eosin (H&E). Paraffin-embedded sections were examined by H&E. Eighteen patients underwent successful SLN mapping procedures. IIC was negative in 84.2 per cent (16) cases. Three false-negatives occurred with IIC, but there were no false-positives, making the sensitivity 33 per cent and the specificity 100 per cent. Two of four patients with positive pathology-confirmed SLN also had positive IIC. SLN mapping has usefulness in patients with MCC. IIC is feasible and accurate in evaluating the SLN. IIC is a practical diagnostic tool when intraoperative analysis of SLN biopsy is desired for MCC.
