Lupus erythematosus tumidus--a neglected subset of cutaneous Lupus erythematosus: report of 40 cases.

BACKGROUND: Lupus erythematosus tumidus (LET) is characterized clinically by erythematous, succulent, edematous, nonscarring plaques in sun-exposed areas. Results of histological examination show perivascular and periadnexal lymphocytic infiltration and interstitial mucin deposition. The main differential diagnoses are polymorphous light eruption, Jessner's lymphocytic infiltration of the skin, reticular erythematous mucinosis, and pseudolymphoma. Since its first description in 1930, LET has been documented rarely in the literature, and its clinical importance has not been fully appreciated. OBSERVATIONS: We characterized 40 patients with clinical and histological features of LET observed at our department from 1984 through 1998. The onset of the disease clustered in summer because of sun exposure, and 28 (70%) of the patients showed a remarkable photosensitivity confirmed by results of provocative phototesting. A complete resolution of the skin lesions was seen after systemic therapy with antimalarials and, in some cases, with local corticosteroids or spontaneously without any treatment. In 4 (10%) of the patients, antinuclear antibodies were detected; however, there was no evidence of underlying systemic involvement in any of the patients. CONCLUSIONS: Our data constitute the largest number of patients with LET collected until now. The clinical picture, extreme photosensitivity, histological findings, and effective treatment with antimalarials are so characteristic that LET should be considered as a separate entity and differentiated from other variants of cutaneous LE.

Safety and efficacy of 1 year of tacrolimus ointment monotherapy in adults with atopic dermatitis. The European Tacrolimus Ointment Study Group.

OBJECTIVE: To investigate the safety and efficacy of using 0.1% tacrolimus ointment for long-term treatment of atopic dermatitis. DESIGN: Open-label, noncomparative study with 6 to 12 months of follow-up. SETTINGS: Outpatient departments in 30 study centers in 11 European countries. PATIENTS: We enrolled 316 patients aged 18 years and older with moderate to severe atopic dermatitis, 200 for 6 months and 116 for 12 months; 77.5% of patients completed the study. INTERVENTION: Twice-daily application of 0.1% tacrolimus ointment on all affected skin. Visits were scheduled on day 1; after 1, 2, and 4 weeks of treatment; and monthly thereafter. MAIN OUTCOME MEASURES: Safety assessments included monitoring of adverse events, clinical laboratory values, and tacrolimus blood concentrations. Efficacy end points included a combined score (modified Eczema Area and Severity Index) and an investigator's global assessment. RESULTS: Local irritation, adverse events such as burning sensation (47% of patients), pruritus (24% of patients), and erythema (12% of patients) were common but tended to occur only when initiating treatment. Laboratory values showed no marked changes over time. Systemic absorption was minimal, with the maximum tacrolimus blood concentration being less than 1 ng/mL in 76% of patients. All efficacy end points showed improvement. The mean (SD) modified Eczema Area and Severity Index score was 23.7 (12.6) at day 1, 13.5 (11.3) at week 1, 6.1 (9.2) at month 6, and 6.1 (8.1) at month 12. Marked or excellent improvement or clearance of disease was reported in 54%, 81%, and 86% of patients at week 1, month 6, and month 12, respectively. CONCLUSION: Up to 1 year of tacrolimus ointment use was safe and effective in patients with atopic dermatitis. Arch Dermatol. 2000;136:999-1006

A trial of oolong tea in the management of recalcitrant atopic dermatitis.

BACKGROUND: Mild cases of atopic dermatitis (AD) generally improve with standard treatment. However, standard treatment fails many patients with recalcitrant AD skin lesions. Study results in animal models have demonstrated that the administration of tea (ie, green, black, or oolong) has suppressed type I and type IV allergic reactions. OBJECTIVE: To test the effectiveness of oolong tea in the treatment of recalcitrant AD. PATIENTS: Although 121 patients with recalcitrant AD were enrolled in the study, 118 patients completed the open study. METHODS: Patients were asked to maintain their dermatological treatment. However, they were also instructed to drink oolong tea made from a 10-g teabag placed in 1000 mL of boiling water and steeped for 5 minutes. This amount was then divided into 3 equal servings and 1 serving was drunk daily after 3 regular meals. Photographs of 2 or 3 representative lesion sites were taken at baseline and at 1 and 6 months and the severity of pruritus was assessed on a 6-point Lickert-like scale ranging from markedly improved (>50% improvement) to worsened. RESULTS: After 1 month of treatment 74 (63%) of the 118 patients showed marked to moderate improvement of their condition. The beneficial effect was first noticed after 1 or 2 weeks of treatment. A good response to treatment was still observed in 64 patients (54%) at 6 months. CONCLUSION: The therapeutic efficacy of oolong tea in recalcitrant AD may well be the result of the antiallergic properties of tea polyphenols.

Efficacy of glycolic acid peels in the treatment of melasma.

BACKGROUND: Melasma is an acquired hypermelanosis that is often recalcitrant to treatment with hypopigmenting agents. OBJECTIVE: To assess the efficacy of 4% hydroquinone cream vs 4% hydroquinone cream combined with glycolic acid peels as treatment for melasma. METHODS: Twenty-one Hispanic women with bilateral epidermal and mixed melasma were enrolled in a split-faced prospective trial lasting 8 weeks. Patients underwent 20% to 30% glycolic acid peels every 2 weeks to one side of the face only in addition to twice-daily full-face application of 4% hydroquinone cream and sun protective factor 25 UV-B sunscreen each morning. Pigmentation was measured objectively using a mexameter and the Melasma Area and Severity Index and subjectively using a linear analog scale and physician and patient global evaluation. RESULTS: Hydroquinone treatment alone and treatment with the combination of hydroquinone and glycolic acid had a significant effect in reducing skin pigmentation compared with baseline (P<.001). However, no significant difference was found using combination therapy compared with hydroquinone alone (P =.75). CONCLUSIONS: Use of 4% hydroquinone and a daily sunscreen is effective in the treatment of melasma; however, the addition of 4 glycolic acid peels did not enhance the hypopigmenting effect of hydroquinone treatment alone.

Skin colonization by Malassezia species in neonates: a prospective study and relationship with neonatal cephalic pustulosis.

OBJECTIVES: To assess skin colonization by Malassezia species in full-term healthy newborns, to investigate factors associated with colonization, and to look at acnelike cephalic pustulosis associated with this carriage. DESIGN: Samples were obtained from neonates and their mothers 0 to 5 days after birth and again 3 weeks later. Clinical patterns of common acnelike pustulosis were reported as mild (<10 papulopustules), moderate (> or =10 papulopustules), or absent. Direct examination and culture of sample. Identification of yeasts was based on microscopic and physiologic criteria. SETTING: A maternity hospital and the pediatric dermatology unit of a university hospital. PARTICIPANTS: Consecutive series of 102 neonates and their mothers. MAIN OUTCOME MEASURES: Incidence of skin colonization and type of Malassezia species found in neonates and correlation with neonatal cephalic pustulosis (neonatal acne). RESULTS: At the first visit, 11 neonates and 36 mothers had cultures positive for Malassezia. Malassezia sympodialis and Malassezia globosa were preferentially cultured. At 3 weeks, 29 (52%) of 56 neonates and 18 (32%) of 56 mothers had cultures positive for only M sympodialis and M globosa. Breastfeeding was not associated with a higher prevalence of Malassezia carriage in neonates. Malassezia colonization was higher when pustulosis was more severe and M sympodialis was found in pustules. CONCLUSIONS: Malassezia colonization begins at birth and increases in the first weeks of life. A high prevalence of M sympodialis in neonates is noted from birth. Its association with neonatal acne is confirmed. Further investigation is needed to study the role of sebum secretion rate and quality in the neonatal period.
