    OBJECTIVE: Epidemiologic studies comparing the incidence and prevalence of systemic lupus erythematosus (SLE) and isolated cutaneous lupus erythematosus (CLE) are few. Olmsted County, Minnesota provides a unique setting for such a study owing to resources of the Rochester Epidemiology Project. We sought to describe and compare the incidence and prevalence of SLE and CLE from 1993-2005.

    METHODS: SLE cases were identified from review of medical records and fulfilled the 1982 American ...

    Importance: Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN) is a spectrum of severe mucocutaneous drug reaction associated with significant morbidity and mortality. A previously developed SJS/TEN-specific severity-of-illness model (Score of Toxic Epidermal Necrolysis [SCORTEN]) has been reported to overestimate and underestimate SJS/TEN-related in-hospital mortality in various populations.

    Objective: To derive a risk prediction model for in-hospital mortality among patients ...

    OBJECTIVES: To examine dermatologic adverse effects of lenalidomide in patients with amyloidosis and multiple myeloma and to determine whether the adverse effects are different when lenalidomide is used alone compared with when it is used in combination with dexamethasone.

    DESIGN: Retrospective review of medical records.

    SETTING: Tertiary referral center.

    PATIENTS: Seventy-five patients with multiple myeloma and 23 patients with amyloidosis participating in clinical trials.

    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 ...

    BACKGROUND: Some patients may have delayed allergic patch test reactions that are not identified with a typical 5-day reading protocol.

    OBJECTIVE: To identify allergens with delayed-positive reactions and to determine whether a late reading (day 7-9) can be substituted for the day-5 reading.

    METHODS: We retrospectively reviewed medical records of patients who underwent patch testing for suspected allergic contact dermatitis from October 1997 through December 2006 and returned for delayed ...

    OBJECTIVE: To determine the population-based incidence of leukocytoclastic vasculitis (LCV).

    PATIENTS AND METHODS: This is a retrospective population-based study of all Olmsted County, Minnesota, residents with a skin biopsy-proven diagnosis of LCV from January 1, 1996, through December 31, 2010.

    RESULTS: A total of 84 patients (mean age at diagnosis, 48.3 years) with newly diagnosed skin biopsy-proven LCV (43 women and 41 men) were identified. The incidence rate (age and sex adjusted to ...

    BACKGROUND: Pyoderma gangrenosum is a diagnosis of exclusion, and the misdiagnosis of pyoderma gangrenosum can result in substantial complications in patients who have other causes of severe cutaneous ulceration.

    METHODS: We reviewed the charts of 240 patients with a diagnosis of pyoderma gangrenosum who were evaluated at our institution from 1975 through 2000, including 157 consecutive patients treated for presumed pyoderma gangrenosum from 1984 through 1992. We also reviewed the ...

    OBJECTIVES: To identify new and existing cases of dermatomyositis and its subtypes in Olmsted County, Minnesota, from 1976 through 2007, and to establish a population-based estimate of the incidence and prevalence of dermatomyositis and amyopathic dermatomyositis.

    DESIGN: Retrospective population-based study.

    SETTING: Community-based epidemiology project. Patients Patients with a diagnosis of dermatomyositis were identified from the Rochester Epidemiology Project.

    BACKGROUND: Patch testing to a standard screening series of allergens in combination with supplemental cosmetic allergens is often used to diagnose allergic contact dermatitis due to personal care products.

    OBJECTIVE: To report results of patch testing to skin care product allergens contained in a standard series and a supplemental cosmetic series and to compare efficacy of this combined series in detecting positive reactions to personal care product allergens with the efficacy of ...

    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 ...

    BACKGROUND: Eosinophil granule proteins, including eosinophil cationic protein (ECP), eosinophil-derived neurotoxin (EDN), eosinophil peroxidase (EPO), and major basic protein (MBP), are prominently deposited in skin in several cutaneous disorders and likely contribute to disease pathology.

    OBJECTIVE: We sought to determine the limit of detection, persistence, and vasopermeabilization activity of the eosinophil granule proteins in skin.

    METHODS: The eosinophil granule proteins were ...

    OBJECTIVES: To assess trends in the cutaneous variants of lupus erythematosus (CLE) and to ascertain the incidence of CLE over the past 4 decades.

    DESIGN: Retrospective population-based study.

    SETTING: Community-based epidemiology project.

    PATIENTS: All Olmsted County, Minnesota, residents with any subtype of CLE between January 1965 and December 2005.

    MAIN OUTCOME MEASURES: Incidence of CLE and disease progression to systemic LE (SLE).

    RESULTS: A total of 156 patients with newly ...

    There are no population-based incidence studies of hidradenitis suppurativa (HS). Using the medical record linkage system of the Rochester Epidemiology Project, we sought to determine the incidence of the disease, as well as other associations and characteristics, among HS patients diagnosed in Olmsted County, Minnesota, between 1968 and 2008. Incidence was estimated using the decennial census data for the county. Logistic regression models were fit to evaluate associations between ...

    OBJECTIVE: Mutations in SCN9A have been reported in (1) congenital insensitivity to pain (CIP); (2) primary erythromelalgia; (3) paroxysmal extreme pain disorder; (4) febrile seizures and recently (5) small fibre sensory neuropathy. We sought to investigate for SCN9A mutations in a clinically well-characterised cohort of patients with CIP and erythromelalgia.

    METHODS: We sequenced all exons of SCN9A in 19 clinically well-studied cases including 6 CIP and 13 erythromelalgia (9 with family ...
