Laser treatment of rosacea: a pathoetiological study.

OBJECTIVE: To study the effect of laser treatment on rosacea, a common facial skin disease with symptoms of blushing, redness, telangiectasis, papules, pustules, and diffuse swelling of the skin, we focused on the stinging sensation and performed immunohistochemical evaluation of nerve density and neuropeptide expression. DESIGN: Clinical investigation as well as the lactic acid (stinger) test was performed before and 3 months after the treatment with flashlamp pulsed dye laser, when skin biopsy specimens were also taken. SETTING: University hospital. PATIENTS: Thirty-two patients with rosacea, all with positive results from the lactic acid "stinger" test, were treated by flashlamp pulsed dye laser. MAIN OUTCOME MEASURES: The biopsy specimens were taken from the stinger-positive areas in the nasolabial folds, fixed in Lanas fixative (10% formalin and 0.4% picric acid), and analyzed for the expression of protein gene product 9.5 (general nerve marker), substance P, calcitonin gene-related peptide, and vasoactive intestinal polypeptide, using a biotinylated streptavidin technique. RESULTS: Thirty-one patients who were stinger positive before treatment showed decreased scores after treatment, and 1 patient had the same stinger test score before and after treatment. The number of protein gene product 9.5-positive fibers in the epidermis (P< .05) as well as the papillary dermis (P< .01) was decreased. This was also the case for substance P in the papillary dermis (P< .001), whereas no evident difference was noted for vasoactive intestinal polypeptide and calcitonin gene-related peptide. No difference was found for contact between nerves and vessels (factor VIII positive). CONCLUSIONS: Laser treatment of rosacea that destroys small vessels has a good medical relevance because it reduces the unpleasant symptoms of the sensitive skin. A neurogenic etiology of stinging may be possible.

Fine-needle aspiration cytology of acne rosacea.

Acne rosacea is a common dermatologic condition which is usually diagnosed by its clinical presentation. This article describes an unusual presentation of acne rosacea and the diagnosis of this condition using fine-needle aspiration biopsy. To our knowledge, the fine-needle aspiration findings of acne rosacea have not been previously described and illustrated in the cytology literature.

Helicobacter pylori immunoproteomes in case reports of rosacea and chronic urticaria.

Rosacea and chronic urticaria are two common skin disorders existing in idiopathic forms. A role of Helicobacter pylori bacterium infection in the aetiopathogenesis of rosacea or chronic urticaria has been suggested although still controversial. The aim of the present study was to establish a relationship between H. pylori infection and rosacea chronic urticaria by means of an immunoproteomic investigation. We analyzed immunoglobulin A (IgA)-, IgG-, and IgE-mediated immune-responses against H. pylori antigens and we identified some bacterial immunoresponsive proteins. A general IgA- and IgE-mediated immune response against antioxidative bacterial proteins was observed. A correlation between the bacterial occurrence and skin diseases pathogenesis is discussed.

Rosacea: disturbed defense against brain overheating.

Tympanic (Tty), esophageal (Tes), forehead, and hand skin temperatures, as well as the forehead evaporation rate were recorded in six men (four suffering from rosacea and two healthy controls) before, during, and after 1 h of warm bath (38 degrees-39 degrees C). During the last 30 min of the bath, the subject's face was vigorously fanned (14 m/s). Blood flow was explored with ultrasonic Doppler in the emissary veins of the cranium during normothermia before entering the bath, and during hyperthermia just after leaving it. Under normothermic conditions, Tty was higher than Tes in all subjects. In three patients, no blood flow could be detected in the ophthalmic emissary veins whereas in the fourth patient as well as in both control subjects, blood flowed from the intracranium to the face. During hyperthermia, face fanning decreased Tty by 0.25 degrees +/- 0.05 degrees C (+/- SEM) below Tes in the control subjects whereas in all patients Tty remained warmer than Tes by 0.1 degrees C. Doppler recordings showed a rapid inward blood flow from the skin to the brain in the controls during hyperthermia. In patients, however, there was no change from normothermia in the blood flow patterns of vena angularis oculi. Their forehead temperature was permanently higher than in control subjects. Venous blood flow from the skin to the brain appears to be suppressed in rosacea, thus inhibiting selective brain cooling in hyperthermic conditions. The importance of this mechanism in the pathogenesis of rosacea and its significance as a means of investigation are discussed.

Medication adherence: a key factor in effective management of rosacea.

Rosacea is a chronic condition associated with relapses. Unsuccessful treatment is predicated, in part, on suboptimal adherence with the medication regimen. Motivating long-term compliance remains a challenge. The literature on adherence with rosacea medication is scant, but data from other diseases suggest that a multifactorial approach combining nonpharmacologic and adherence-enhancing pharmacologic interventions appears to offer the greatest success. The variety of topical metronidazole formulations that are relatively well tolerated and convenient to administer has been a notable advance in rosacea management. The dermatologist, by emphasizing the importance of adherence with therapy, can do much to facilitate this most critical behavior.

[Rosacea fulminans, pyostomatitis and pyovulvitis in Crohn's disease: dapsone as key factor in combination therapy].

Rosacea fulminans (also known as pyoderma faciale) has been reported to occur in association with Crohn's disease. It is still unclear whether the papulopustules and confluent nodules of rosacea fulminans represent a manifestation of mucocutaneous Crohn's disease or whether this association is a mere coincidence. A 46-year-old woman presented with the spontaneous outbreak of rosacea fulminans and pyostomatitis/pyovulvitis. Complete remission of the mucocutaneous symptoms was achieved with 2 months combination therapy with methylprednisolone, isotretinoin and dapsone. The patient's Crohn's disease, already diagnosed for 3 years, did not flare during this period.

[Dapsone in granulomatous rosacea].

We report on two patients with granulomatous rosacea and another patient with granulomatous perioral dermatitis who responded well to dapsone. Dapsone has a pharmacological double function as both an antibiotic and an antiphlogistic drug. Before the introduction of isotretinoin, dapsone had its place in the treatment of severe acne. To date, its use in granulomatous rosacea has not been described. When hematologic parameters are monitored, dapsone is considered a safe and cost-effective drug, especially in countries where isotretinoin is not readily available. However, the definite value of dapsone in granulomatous rosacea should be established by a controlled study.

A clinical and histopathologic study of granulomatous rosacea.

A retrospective clinical and histopathologic study of 53 patients with granulomatous rosacea was undertaken. The patients had a broad clinical spectrum of lesions that ranged from primarily erythema to papulonodular lesions. Extrafacial lesions occurred in 15% of patients. Histologic examination showed mixed lymphohistiocytic inflammation (primarily lymphocytic inflammation in 40% of patients and primarily histiocytic with a few giant cells in 34%), epithelioid granulomas in 11% of patients, and epithelioid granulomas with caseation necrosis in 11%. Most patients had a good response to oral antibiotic therapy. Granulomatous rosacea is not a distinct disease but can be regarded and treated as a subtype of rosacea.

Pediatric ocular acne rosacea: long-term treatment with systemic antibiotics.

PURPOSE: To report our experience with four cases of pediatric ocular acne rosacea, including responses to long-term systemic treatment. DESIGN: Retrospective interventional case series. METHODS: The medical records of four consecutive cases diagnosed with pediatric ocular acne rosacea over a period of 36 months were reviewed. Diagnostic criteria were meibomian gland dysfunction, blepharitis, lid margin telangiectasia, punctate superficial keratopathy, and conjunctival hyperemia with or without inferior corneal vascularization. RESULTS: The patients, aged between four and 12, were all females with bilateral disease. Meibomitis, blepharitis, conjunctival hyperemia, and punctuate epitheliopathy was evident in each case. Cutaneous involvement was seen in two cases (50%), and limbal vascularization with subepithelial or stromal infiltrates was present in three cases (75%). One case showed corneal ulceration at presentation. All four children received systemic doxycycline or erythromycin for at least 12 months and showed considerable improvement within the first month of therapy. No recurrence was noted within the mean 25.5 months of follow-up. None of the girls experienced any side effects during the long treatment duration. CONCLUSIONS: Ophthalmologists should consider acne rosacea as a potential diagnosis for any child who has any combination of meibomian disease, chronic blepharitis, recurrent chalazia, and chronic symptoms of photophobia, ocular irritation, and redness that does not respond to routine medical treatment. Such patients respond very well to long-term treatment with systemic erythromycin/doxycycline.

Pulsed dye laser treatment of rosacea improves erythema, symptomatology, and quality of life.

BACKGROUND: Persistent erythema and dysesthetic symptoms are typical manifestations of rosacea. OBJECTIVE: We sought to assess improvement in erythema, symptoms, and quality of life after pulsed dye laser treatment. METHODS: Sixteen patients with erythematotelangiectatic rosacea participated. Spectrophotometric erythema measurements were taken from the right and left malar prominence; chin; and nasal alae, dorsum, and tip. A questionnaire rating the Dermatology Life Quality Index and symptoms of flushing, burning, itching, dryness, swelling, and skin sensitivity was completed. Treatment was undertaken with the pulsed dye laser at purpuragenic fluences. Measurements and treatment were repeated at 8-week intervals for a total of two treatments. RESULTS: A statistically significant improvement was observed in symptoms, quality-of-life score, and erythema in all areas with the exception of erythema of the left nasal ala. CONCLUSIONS: Pulsed dye laser treatment at purpuragenic fluences is a safe and effective treatment for symptomatic rosacea, resulting in a significant improvement in erythema, symptoms, and quality of life.

A randomized, double-blind, placebo-controlled trial of the combined effect of doxycycline hyclate 20-mg tablets and metronidazole 0.75% topical lotion in the treatment of rosacea.

BACKGROUND: Subantimicrobial doses of doxycycline may improve outcomes in rosacea when combined with topical metronidazole and used as maintenance monotherapy. OBJECTIVE: The purpose of this study was to evaluate the safety and efficacy of doxycycline hyclate 20 mg (subantimicrobial dose doxycycline) administered twice daily as an adjunct to metronidazole 0.75% topical lotion in the treatment of rosacea. METHODS: Patients received subantimicrobial doses of doxycycline twice daily plus metronidazole (n = 20) or placebo plus metronidazole (n = 20) for 12 weeks. Subantimicrobial-dose doxycycline or placebo monotherapy continued for 4 weeks. The primary efficacy measure was change from baseline in total inflammatory lesions at weeks 2 and 16. RESULTS: Total inflammatory lesions were reduced significantly (P =.048) by week 4 and by all subsequent visits in the subantimicrobial-dose doxycycline/metronidazole group compared with placebo/metronidazole. Changes from baseline increased over time and were maintained during subantimicrobial-dose doxycycline monotherapy. CONCLUSION: Adjunctive use of subantimicrobial dose doxycycline significantly reduced the clinical signs of rosacea compared with metronidazole alone and may be useful maintenance monotherapy.

Ocular rosacea in childhood.

PURPOSE: To describe the clinical characteristics and treatment response of ocular rosacea in the pediatric population. DESIGN: Retrospective case series. METHODS: The clinic charts of consecutive pediatric cases of ocular rosacea were evaluated over a 34-month period. Minimal diagnostic inclusion criteria were the presence of posterior eyelid inflammation including meibomian gland inspissation and lid margin telangiectasis, in conjunction with conjunctival injection or episcleritis. RESULTS: Six patients ranged from 3 to 12 years of age at presentation. All shared a long history of ocular irritation and photophobia. Five patients (83%) were female and had bilateral involvement. Eyelid telangiectases and meibomian gland disease were present in all cases. Three patients (50%) had sterile corneal ulcers. Only two patients (33%) had cutaneous involvement at the time of diagnosis. All patients experienced significant improvement with a combination of oral antibiotics (doxycycline or erythromycin), with or without topical antibiotics (erythromycin or bacitracin) or topical steroids (fluorometholone). CONCLUSION: Ocular rosacea in children may be misdiagnosed as viral or bacterial infections. Unlike in adults, associated cutaneous changes are uncommon. Most disease is bilateral, although involvement may be asymmetric. Response to conventional treatment is excellent, although long-term treatment may be necessary to prevent relapses.

Efficacy of doxycycline and tetracycline in ocular rosacea.

We compared the effects of doxycycline and tetracycline hydrochloride on the subjective symptoms in ocular rosacea. Twenty-four patients with symptomatic ocular rosacea were randomly assigned to two groups and treated with doxycycline 100 mg/day (group 1, 16 patients) or tetracycline hydrochloride 1 g/day (group 2, eight patients). The dosages of each drug were gradually tapered and discontinued according to symptomatic response. At each examination all the manifesting symptoms were scored by the patients. Patients were followed up from six weeks to three years. After six weeks of drug treatment, all patients except one had symptomatic improvement. Although most of the scores of the symptoms were significantly decreased in both groups, greater symptomatic relief occurred in the tetracycline hydrochloride-treated patients (P = .041). However, after three months of treatment there was no significant difference in symptoms between the two groups. Gastrointestinal tract complications occurred in two of the 16 patients (12.5%) in group 1 and in three of the eight patients (37.5%) in group 2. Both tetracycline hydrochloride and doxycycline can control the symptoms of ocular rosacea.

Tear studies in ocular rosacea.

To determine whether tear pH in ocular rosacea was alkaline or acidic compared to normal, I studied tear pH measured by pH electrode or paper in 12 patients with rosacea without ocular manifestations, 23 patients with mild ocular manifestations, and nine patients with severe ocular manifestations. There was no diagnostically useful difference in tear pH between any of these groups and normal controls. Possible pitfalls include the effect of anesthetic eyedrops on tear pH, the effect of basal tear secretion, and discrepancies between electrode and paper measurements. Measurements by pH paper cannot be adjusted by an error constant to yield an equivalent electrode value. Treatment of active ocular rosacea with tetracycline for one month had no effect on tear pH in six patients.

Rosacea.

Rosacea is a common skin disorder most often seen in individuals between the ages of 30 and 60. The condition frequently produces erythema, papules, pustules, and edema of midfacial skin. Ocular rosacea occurs in a high percentage of patients, and is a major cause of red eye. A variety of treatments exist that can eliminate pustules, but no therapy is highly effective in eliminating the vascular flushing associated with rosacea.

The efficacy of topical metronidazole in the treatment of ocular rosacea.

PURPOSE: The purpose of the study is to investigate the efficacy of metronidazole topical gel in the treatment of ocular rosacea. METHODS: Ten patients with ocular rosacea were treated prospectively with lid hygiene and topical metronidazole applied to the lid margin in one eye and lid hygiene alone in the fellow eye. The treatment period was 12 weeks. A masked observer graded the ocular findings at the initial visit and at the conclusion of the treatment period. Pretreatment scores were compared with post-treatment scores with respect to ocular surface, eyelid margin, and combined eyelid plus ocular surface. RESULTS: Eight of ten treated eyes improved, whereas only five of ten control eyes improved. There was a statistically significant improvement in the eyelid score in both the treated and control groups (P = 0.003, P = 0.025, respectively), but no significant improvement in the ocular surface score in either group. When the pretreatment and post-treatment eyelid and ocular surface scores were combined, there was a significant improvement in the treated eyes but not in the control eyes (P = 0.022, P = 0.10, respectively). No adverse effects of the metronidazole treatment were encountered in this study. CONCLUSION: Metronidazole topical gel may be a safe and effective means of treating rosacea blepharitis.

Cutaneous angiosarcoma of the face: clinicopathologic and immunohistochemical study of a case resembling rosacea clinically.

An unusual cutaneous angiosarcoma resembling rosacea clinically is described. A 66-year-old man presented with a red discoloration and a diffuse swelling on his nose over a 2-year period that was diagnosed as rosacea. Despite antiinflammatory treatment, the infiltration increased and, after repeated skin biopsies, the diagnosis of a well-differentiated cutaneous angiosarcoma associated with a prominent inflammatory infiltrate was considered. The neoplasm was treated by surgery. The described case emphasizes that diffuse swelling and rosacea-like clinical features should be added to the variably clinical features of cutaneous angiosarcoma.
