[source] Comparison of efficacy of azithromycin vs. doxycycline in the treatment of rosacea: a randomized open clinical trialINTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 3 2008Maryam Akhyani MD Background, Rosacea is a common inflammatory disorder of the skin. Systemic antibiotics currently used in the treatment of rosacea are sometimes associated with uncomfortable side effects. Therefore, a need for an effective agent with few side effects and good patient compliance exists. Azithromycin, a macrolide antibiotic with prolonged mode of action, has recently been found to be an effective alternative in the treatment of inflammatory acne. Methods, For evaluation of the efficacy of azithromycin in the treatment of rosacea, we planned a randomized, open, clinical trial study to compare the efficacy of azithromycin with doxycycline in the treatment of this disease. Sixty-seven patients were randomized to receive either azithromycin 500 mg thrice weekly (on Monday, Wednesday, and Saturday) in the first, 250 mg thrice weekly (on Monday, Wednesday, and Saturday) in the second, and 250 mg twice weekly (on Tuesday, and Saturday) in the third month. The other group was given doxycycline 100 mg/day for the three months. Clinical assessment was made at baseline, at the end of first, second, third, and 2 months after treatment. Side affects were recorded. The limitation of this study is that there was no blindness. Results, Statistically significant improvement was obtained with both drugs. Neither drug was shown to be more effective than the other. In the azithromycin group four patients had diarrhea, while epigastric burning was seen in two patients using doxycycline. Conclusion, This study indicates that azithromycin is at least as effective as doxycycline in the treatment of rosacea. [source] Current topical and systemic approaches to treatment of rosaceaJOURNAL OF THE EUROPEAN ACADEMY OF DERMATOLOGY & VENEREOLOGY, Issue 8 2009HC Korting Abstract Rosacea is a common, often overlooked, chronic facial dermatosis characterized by intermittent periods of exacerbation and remission. Clinical subtypes and grading of the disease have been defined in the literature. On the basis of a genetic predisposition, there are several intrinsic and extrinsic factors possibly correlating with the phenotypic expression of the disease. Although rosacea cannot be cured, there are several recommended treatment strategies appropriate to control the corresponding symptoms/signs. In addition to adequate skin care, these include topical and systemic medications particularly suitable for the papulopustular subtype of rosacea with moderate to severe intensity. The most commonly used and most established therapeutic regimens are topical metronidazole and topical azelaic acid as well as oral doxycycline. Conventionally, 100,200 mg per day have been used. Today also a controlled release formulation is available, delivering 40 mg per day using non-antibiotic, anti-inflammatory activities of the drug. Anti-inflammatory dose doxycycline in particular allows for a safe and effective short- and long-term therapy of rosacea. Topical metronidazole and topical azelaic acid also appear to be safe and effective for short-term use. There are indications that a combined therapy of anti-inflammatory dose doxycycline and topical metronidazole could possibly have synergy effects. Further interesting therapy options for the short- and long-term therapy of rosacea could be low-dose minocycline and isotretinoin; however, too little data are available with regard to the effectiveness, safety, optimal dosage and appropriate length of treatment for these medications to draw final conclusions. Conflicts of interest None declared. [source] A randomized, single-blind, placebo-controlled, split-face study with pimecrolimus cream 1% for papulopustular rosaceaJOURNAL OF THE EUROPEAN ACADEMY OF DERMATOLOGY & VENEREOLOGY, Issue 6 2008AA Karabulut Abstract Background, Rosacea is a common inflammatory skin disorder for which the pathogenesis is unclear. Currently, there is no cure for rosacea, and it seems that standard therapies have focused mainly on minimizing inflammation. Objectives, The aim of this study is to investigate the potential efficacy, tolerability and safety profile of 1% pimecrolimus cream for the treatment of rosacea. Methods, Twenty-five patients with papulopustular rosacea were enrolled to a randomized, single-blinded, placebo-controlled, split-face trial of pimecrolimus cream 1% consisting 4 week treatment and 2 week follow-up period. The patients were instructed to apply first the ,left side cream' labelled placebo cream (Ultrabase cream, Intendis GmbH, Berlin, Germany) to the left hemi-face then the ,right side cream' labelled 1% pimecrolimus cream (Elidel; Novartis Pharma, Nuremberg, Germany) to the right hemi-face, twice daily. They were informed to apply a standard amount of each cream with the fingertip-unit and not allowed to use any other agent concomittantly other than sunblock. Clinical evaluation and subjective severity assessment were obtained along with photographic documentation at baseline, first, second, and fourth weeks of the therapy and at the follow-up visit. Rosacea severity score for each sign of erythema, papules, pustules, oedema, and telengiectesia were graded from 0 to 3. Patients were questioned for the subjective symptoms, overall improvement on appearance and side-effects. Results, Twenty-four patients completed the study with an exceptional compliance and tolerable safety profile. One patient withdrew from the study due to severe flare-up reaction affecting both hemi-faces. The mean baseline total rosacea severity scores were 5.06 + 1.29 for both sides and reduced to 2.5 ± 1.06 vs. 3.25 ± 1.24 on pimecrolimus vs. placebo applied sides without the significance (P = 0.06). There was not any significant difference concerning each rosacea sign scores and total rosacea severity scores except for the significant improvement in erythema score and total rosacea severity score obtained on the pimecrolimus-applied hemi-face at 2nd week of therapy (P =0.01 and P = 0.03, respectively). The reduction rates of the mean subjective severity scores at 4th week were 49.77% vs. 38.89% for pimecrolimus vs. placebo, respectively, without a statistical significance (P = 0.15). Subjective symptoms responded well in 54.16% of patients concerning pimecrolimus application compared with 12.50% for the placebo application. The side-effects were mostly transient local irritations. Conclusion, Our data implicated that pimecrolimus cream is not superior to placebo except for its efficacy on erythema. We believe that pimecrolimus cream can be a treatment option for rosacea patients with high erythema score for whom an initial accelerated improvement is needed. We believe further studies with topical pimecrolimus cream on larger study groups with different subtypes and severity of rosacea will clarify the potential effect of pimecrolimus cream for the treatment of rosacea. [source] Rosacea and its management: an overviewJOURNAL OF THE EUROPEAN ACADEMY OF DERMATOLOGY & VENEREOLOGY, Issue 3 2005AK Gupta ABSTRACT Background, Rosacea is a chronic inflammatory disorder that affects 10% of the population. The prevalence of rosacea is highest among fair-skinned individuals, particularly those of Celtic and northern European descent. Since a cure for rosacea does not yet exist, management and treatment regimens are designed to suppress the inflammatory lesions, erythema, and to a lesser extent, the telangiectasia involved with rosacea. Objectives, This review outlines the treatment options that are available to patients with rosacea. Methods, Published literature involving the treatment or management of rosacea was examined and summarized. Results, Patients who find that they blush and flush frequently, or have a family history of rosacea are advised to avoid the physiological and environmental stimuli that can cause increased facial redness. Topical agents such as metronidazole, azelaic acid cream or sulfur preparations are effective in managing rosacea. Patients who have progressed to erythematotelangiectatic and papulopustular rosacea may benefit from the use of an oral antibiotic, such as tetracycline, and in severe or recalcitrant cases, isotretinoin to bring the rosacea flare-up under control. Treatment with a topical agent, such as metronidazole, may help maintain remission. Patients with ocular involvement may benefit from a long-term course of an antibiotic and the use of metronidazole gel. A surgical alternative, laser therapy, is recommended for the treatment of telangiectasias and rhinophyma. Patients with distraught feelings due to their rosacea may consider cosmetic camouflage to cover the signs of rosacea. Conclusions, With the wide variety of oral and topical agents available for the effective management of rosacea, patients no longer need to feel self-conscious because of their disorder. [source] GSTM1 and GSTT1 null genotypes as possible heritable factors of rosaceaPHOTODERMATOLOGY, PHOTOIMMUNOLOGY & PHOTOMEDICINE, Issue 4 2006Ayca Cordan Yazici Purpose: Rosacea might be related to an increased activity of reactive oxygen species (ROS) and deficient function of the antioxidant system. Glutathione S-transferases (GSTs) play a primer role in cellular defense against electrophilic chemical species and radical oxygen species. We hypothesized that increased ROS activity or decreased antioxidant potential, possibly induced by GST gene polymorphism, might have a pathogenic role in rosacea. Methods: The study group consisted of 45 patients with rosacea and 100 control subjects. DNA samples were isolated from blood samples using high pure polymerase chain reaction (PCR) Template preparation Kit. The GSTM1, GSTT1, and P1 polymorphisms were detected using a real-time PCR and fluorescence resonance energy transfer with a Light-Cycler Instrument. Associations between specific genotypes and the development of rosacea were examined using logistic regression analyses to calculate odds ratios (OR) and 95% confidence intervals (CI). Results: GSTM1 and GSTT1 null genotypes were found to be statistically different from control (P=0.005, P=0.009, respectively), and associated with an increased risk of rosacea (OR [95% CI]: 2.84 [1.37,5.89]; OR [95% CI]: 2.68 [1.27,5.67], respectively). There was a statistically significant relationship between both null combination of the GSTM1 and GSTT1 genotype polymorphisms and rosacea (P=0.003, OR [95% CI]: 4.18 [1.57,11.13]). There were no statistically significant differences between patient and control groups for the GSTP1 Ile/Ile, Ile/Val, and Val/Val genotypes (P>0.05). Conclusion: We demonstrated a significant association between the GSTT1 and/or GSTM1 null genotypes and rosacea. However, the potential role of GSTs as markers of susceptibility to rosacea needs further studies in larger patient groups.

Copyright © 2008 Wiley Interface Ltd [source] Childhood ocular rosacea: Considerations for diagnosis and treatmentAUSTRALASIAN JOURNAL OF DERMATOLOGY, Issue 4 2009Esther Hong ABSTRACT Rosacea in children is not as well described as it is in adults. Ocular signs may be a dominant feature and some children with what has previously been called periorificial dermatitis may in fact have rosacea. We report three cases of paediatric ocular rosacea responding to prolonged treatment with oral erythromycin. Our cases demonstrate the close association of periorificial dermatitis with childhood rosacea, and highlight the importance of eye signs in its diagnostic criteria. [source] P43 Acute urticaria to infliximabCONTACT DERMATITIS, Issue 3 2004Ana Giménez-Arnau Infliximab is a chimeric antitumor necrosis factor-alpha monoclonal antibody used to treat Crohn's disease and rheumatoid arthritis. Acute infusion reactions, headache, fever, chills, urticaria and chest pain were seen in 17% of patients with infliximab compared with 7% of those receiving placebo. Other adverse cutaneous reactions are fungal dermatitis, eczema, seborrhoea, hordeolum, bullous eruption, furunculosis, periorbital oedema, hyperkeratosis, rosacea, verruca, skin pigmentation, alopecia, leukocytoclastic vasculitis, lichenoid drug eruption, erythema multiforme, perniosis-like eruption, granuloma annulare and acute folliculitis. Any pathogenic mechanism has been suggested. Patch test with infliximab can induce flare-up of lesions, nausea and malaise and suggest a percutaneous absortion. A sixty years-old man with atopy background and rheumatoid arthritis treated with Remicare®, infliximab who developed a severe acute urticaria with angioedema is presented. The lesions appearance after previous endovenous administrations and the worsening spreading wheals days after the injection clinically suggested an hypersensitivity mechanism. The protocolized study drug hypersensitivity performed showed only the Prick Test positivity with infliximab at 30/60 minutes. Patch test with infliximab was negative and any adverse event was reported. Actually the patient is treated with etanercept and this drug is well tolerated. This result suggested a type I hypersensitivity mediated reaction. Urticaria could be induced as immunologic reaction of the host against the murine part of infliximab, just as it hapens with other antichimeric antibodies. [source] Granulomatous rosacea and Crohn's disease in a patient homozygous for the Crohn-associated NOD2/CARD15 polymorphism R702WEXPERIMENTAL DERMATOLOGY, Issue 12 2008M. A. M. Van Steensel Abstract:, NOD2/CARD15 belongs to the N-terminal caspase recruitment domain family of proteins involved in regulating NF-kB activation in response to inflammatory stimuli transduced through Toll-like receptors. Mutations and polymorphisms in the NOD2/CARD15 gene reduce antibacterial responses and are associated with granulomatous inflammatory conditions such as Blau syndrome and early-onset sarcoidosis. The polymorphism R702W (arginine to tryptophan) is strongly associated with susceptibility to Crohn's disease in Caucasian populations. Skin abnormalities (other than cutaneous manifestations of Crohn's disease) have not been previously associated with R702W. We report on a female patient homozygous for R702W who developed granulomatous rosacea at the age of 12 years old. From the occurrence in the context of Crohn associated with R702W, we speculate that granulomatous rosacea may be an entity distinct from other forms of rosacea, which are associated with increased production of antibacterial proteins such as cathelicidin.

[source] Severe rosacea associated with colon cancer recurrenceINTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 3 2004L. Margolin MD An 80-year-old male, who had undergone orchiectomy because of prostatic cancer, presented with rosacea (for the first time in his life), weight loss and anemia, and was diagnosed with local recurrence of colon cancer. The hormonal disarrangement unbalance after orchiectomy and a paraneoplastic vasoactive substance may have contributed to the development of rosacea in this patient. [source] Extensive xanthelasma associated with anaplastic large cell lymphoma and hyperimmunoglobulin E syndromeINTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 12 2003Mi-Woo Lee MD A 57-year-old woman presented with a 6-month history of an extensively spreading, yellowish patch on the periorbital areas and cheeks. A diagnosis of hyperimmunoglobulin E syndrome had been made at the age of 22 years on the basis of an eczematous eruption, recurrent furunculosis, and a persistently elevated immunoglobulin E (IgE) level. Her past medical history revealed that she had suffered from numerous recurrent bouts of chronic sinusitis, otitis media, oral candidiasis, orbital cellulitis, acne rosacea, and pneumonia caused by cytomegalovirus since her twenties. In addition, 1 year ago, anaplastic large cell lymphoma of the cervical lymph node (stage IIIb) developed, and she received six cycles of cyclophosphamide,doxorubicin,vincristine,prednisolone (CHOP) chemotherapy with partial remission. None of her family had any of these problems. Cutaneous examination showed extensive, symmetric, noninfiltrated macular areas of distinct yellow discoloration around the eyes and on both cheeks (Fig. 1). There were also erythematous papulonodular eruptions on the nose and both cheeks, which were thought to be acne rosacea. Laboratory findings were normal, except for an elevated IgE level (8157 IU/mL). Serum concentrations of IgG, IgA, and IgM were normal. Serum complement levels were normal, as evidenced by normal C3, C4, and CH50. Although she had a previous history of a decreased level (12%) of nitroblue tetrazolium (NBT) test (control, 53%), NBT test at our institute was normal. Neutrophil function tests, including neutrophil chemotaxis, neutrophil phagocytosis, neutrophil respiratory burst, and neutrophil microbial killing test, by flow cytometry, showed normal results. The serum lipid levels, including total cholesterol, triglyceride, low-density lipoprotein-cholesterol, and high-density lipoprotein-cholesterol, were normal. Serum lipoprotein electrophoresis was normal. A biopsy specimen revealed scattered foamy cells throughout the dermis. The larger clusters of foamy cells tended to group around the blood vessels of the dermis (Fig. 2). Figure 1. Extensively distributed, yellowish, flat xanthelasma on the face Figure 2.

We report a case of a 45-year-old woman with a history of persistent erythematous malar rash, associated with conjunctival hyperemia, xerophthalmia and blefaritis. The patient filled the current classification criteria proposed for Sjögren's syndrome and those for rosacea. The coexistence of these diseases has not been previously described in the literature. Both diseases have similar symptoms and different treatment approaches. We believe that it is important for clinicians to identify this association in order to provide better care for the patient. [source] Periorbital dermatitis: Causes, differential diagnoses and therapyJOURNAL DER DEUTSCHEN DERMATOLOGISCHEN GESELLSCHAFT, Issue 3 2010Alexandra Feser Summary Periorbital dermatitis is common and frequently difficult to treat. Patients with periorbital dermatitis often suffer severely because their disease is in such a visible location. Because of the variety of clinical appearance, the differential diagnostic considerations are often difficult. We examined the causes of periorbital dermatitis and compared the data of 88 patients from the Department of Dermatology, University Hospital Erlangen to those of the German IVDK (Information Network of the Departments of Dermatology). Between 1999 and 2004, predominant causes of periorbital dermatitis were allergic contact dermatitis (Erlangen 44 %, IVDK 32 %), atopic eczema (Erlangen 25 %, IVDK 14 %), airborne contact dermatitis (Erlangen 10 %, IVDK 2 %) and irritant contact dermatitis (Erlangen 9 %, IVDK 8 %). Less frequent causes for secondary eczematous periocular skin lesions were periorbital rosacea, allergic conjunctivitis or psoriasis vulgaris. Female gender, atopic skin diathesis and age of 40 years and older were identified as risk factors for periocular dermatitis. Common elicitors of periorbital allergic contact dermatitis were leave-on cosmetic products (face cream, eye shadow) and eye drops with the usual allergens being fragrances, preservatives and drugs. Exact identification of relevant contact allergens and allergen elimination are essential for successful treatment. Calcineurin inhibitors are the first-line therapy for facial atopic eczema. They may be also effective in periocular eczematous lesions of other origins although they are not approved for such use. [source] A12. IPL therapy in the inflammatory stage of rosaceaJOURNAL OF COSMETIC DERMATOLOGY, Issue 2 2002M Rone The inflammatory stage of Rosacea iscommonly treated with topical or oral antibiotics. However, if additional erythema and telangiectasias are present, antibiotics are not successful. IPL (intense pulsed light) is mostly involved when only initial or residual telangiectasias are present. Application of IPL simultaneously with topical or oral medicine could be an effective form of treatment in the inflammatory stage of rosacea. This study was performed in order to detect the effect of IPL application with simultaneous topical antibiotics in inflammatory rosacea and to assess the efficacy of IPL therapy in routine treatment of rosacea. Twenty patients aged between 34 and 70 with papulopustular rosacea (14 female and 7 male) were included in the study. Ten patients (group I) were treated for 21 weeks with topical metronidazole. The other ten patients (group II) received an additional 3 sessions with IPL 515,755 nm Photoderm VL technology over 4 weeks. Treatment affectivity was recorded by digital visualisation and patient satisfaction scale before each IPL session. In all patients, significant reductions in papulopustular elements were observed. Eight out of 10 patients (group I) still showed permanent erythema and telangiectasias despite topical treatment. In 3/10 patients a few telangiectasias remained following the treatment in contrast to 5/10 satisfied group I patients. The most effective treatment was the application of 570 nm and 590 nm wavelength at a fluence of 25,55 J/cm2. Application of IPL in inflammatory rosacea is equally as safe and effective in residual or initial lesions. Moreover, in combination with antibiotics, it promotes reduction of all symptoms, is less time-consuming and is more successful for patients. The pathogenetic influence of IPL in rosacea seems not only to be limited to selective photothermolysis of dilated blood vessels, but may also have immunomodulatory effects on inflammatory processes and possibly on collagen remodelling. The combination of IPL and antibiotics from theoutset of rosacea therapy is considered to be highly effective. [source] Localized lymphedema (elephantiasis): a case series and review of the literatureJOURNAL OF CUTANEOUS PATHOLOGY, Issue 1 2009Song Lu Background:, Lymphedema typically affects a whole limb. Rarely, lymphedema can present as a circumscribed plaque or an isolated skin tumor. Objective:, To describe the clinical and pathologic characteristics and etiologic factors of localized lymphedema. Methods:, Case,control study of skin biopsy and excision specimens histologically diagnosed with lymphedema and presenting as a localized skin tumor identified during a 4-year period. Results:, We identified 24 cases of localized lymphedema presenting as solitary large polyps (11), solid or papillomatous plaques (7), pendulous swellings (4), or tumors mimicking sarcoma (2). Patients were 18 females and 6 males with a mean age of 41 years (range 16,74). Anogenital involvement was most frequent (75%) , mostly vulva (58%), followed by eyelid (13%), thigh (8%) and breast (4%). Causative factors included injury due to trauma, surgery or childbirth (54%), chronic inflammatory disease (rosacea, Crohn's disease) (8%), and bacterial cellulitis (12%). Eighty-five percent of these patients were either overweight (50%) or obese (35%). Compared with a series of 80 patients with diffuse lymphedema, localized lymphedema patients were significantly younger (41 vs. 62 years old, p = 0.0001), had no history of cancer treatment (0% vs. 18%, p = 0.03), and had an injury to the affected site (54% vs. 6%, p = 0.0001). Histologically, all cases exhibited dermal edema, fibroplasia, dilated lymphatic vessels, uniformly distributed stromal cells and varying degrees of papillated epidermal hyperplasia, inflammatory infiltrates and hyperkeratosis. Tumor size significantly and positively correlated with history of cellulitis, obesity, dense inflammatory infiltrates containing abundant plasma cells, and lymphoid follicles (p < 0.05). A history of cellulitis, morbid obesity, lymphoid follicles and follicular cysts predicted recurrent or progressive swelling despite excision (p < 0.05). Conclusions:, Localized lymphedema should be considered in the etiology of skin tumors when assessing a polyp, plaque, swelling or mass showing dermal edema, fibrosis and dilated lymphatics on biopsy. A combination of lymph stasis promoting factors (trauma, obesity, infection and/or inflammatory disorders) produces localized elephantiasis. [source] Lymphangiogenesis and angiogenesis in non-phymatous rosaceaJOURNAL OF CUTANEOUS PATHOLOGY, Issue 10 2007Amal H. A. Gomaa Background:, Our study evaluated the expression of vascular endothelial growth factor (VEGF), CD31 and D2-40 in involved and uninvolved skin of 18 patients with rosacea. Methods:, Immunostaining of facial skin specimens with VEGF, CD31 and D2-40 was compared between the lesional and the non-lesional skin of patients with erythemotelangiectatic and papulopustular rosacea. Results:, Significantly increased dermal expression of VEGF in lesional vs. non-lesional skin (88.9% and 55.6%) was observed. Dermal expression of CD31 and D2-40 was also increased in lesional vs. non-lesional skin. There was no statistically significant difference in cutaneous expression of VEGF, CD31 and D2-40 between patients with papulopustular and erythemotelangiectatic rosacea, and no correlation was found between disease duration and immunoreactivity of VEGF, CD31or D2-40. Conclusions:, Our study showed marked immunostaining of lesional skin with VEGF, CD31 and D2-40 compared with non-lesional skin. Increased immunoreactivity of D2-40 in lesional skin is interesting, given that none of the patients had facial edema. There are no published data regarding the role of lymphangiogenesis in patients with non-phymatous rosacea; thus, our study represents a new understanding of its pathogenesis. Lack of correlation between D2-40 expression and disease duration suggests that lymphatics are involved early in the pathogenesis of rosacea and do not constitute a late event.

[source] Periocular dermatitis: a report of 401 patientsJOURNAL OF THE EUROPEAN ACADEMY OF DERMATOLOGY & VENEREOLOGY, Issue 2 2009E Temesvári Abstract Background, Periocular contact dermatitis may appear as contact conjunctivitis, contact allergic and/or irritative eyelid and periorbital dermatitis, or a combination of these symptoms. The clinical symptoms may be induced by several environmental and therapeutic contact allergens. Objectives, The aim of the present study was to map the eliciting contact allergens in 401 patients with periocular dermatitis (PD) by patch testing with environmental and ophthalmic contact allergens. Methods, Following the methodics of international requirements, 401 patients were tested with contact allergens of the standard environmental series, 133 of 401 patients with the Brial ophthalmic basic and supplementary series as well. Results, Contact hypersensitivity was detected in 34.4% of the patients. Highest prevalence was seen in cases of PD without other symptoms (51.18%), in patients of PD associated with ophthalmic complaints (OC; 30.4%), and PD associated with atopic dermatitis (AD; 27.9%). In the subgroup of PD associated with seborrhoea (S) and rosacea (R), contact hypersensitivity was confirmed in 17.6%. Most frequent sensitisers were nickel sulphate (in 8.9% of the tested 401 patients), fragrance mix I (4.5%), balsam of Peru (4.0%), paraphenylendiamine (PPD) (3.7%), and thiomersal (3.5%). By testing ophthalmic allergens, contact hypersensitivity was observed in nine patients (6.7% of the tested 133 patients). The most common confirmed ophthalmic allergens were cocamidopropyl betaine, idoxuridine, phenylephrine hydrochloride, Na chromoglycinate, and papaine. Limitations, Patients with symptoms of PD were tested from 1996 to 2006. Conclusions, The occurence of contact hypersensitivity in PD patients was in present study 34.4%. A relatively high occurence was seen in cases of PD without other symptoms, in PD + OC and in PD + AD patients. The predominance of environmental contact allergens was remarkable: most frequent sensitizers were nickel sulphate, fragrance mix I, balsam of Peru, thiomersal, and PPD. The prevalence of contact hypersensitivity to ophthalmic allergens did not exceed l.5%.

Currently, there is no cure for rosacea, and it seems that standard therapies have focused mainly on minimizing inflammation. Objectives, The aim of this study is to investigate the potential efficacy, tolerability and safety profile of 1% pimecrolimus cream for the treatment of rosacea. Methods, Twenty-five patients with papulopustular rosacea were enrolled to a randomized, single-blinded, placebo-controlled, split-face trial of pimecrolimus cream 1% consisting 4 week treatment and 2 week follow-up period. The patients were instructed to apply first the ,left side cream' labelled placebo cream (Ultrabase cream, Intendis GmbH, Berlin, Germany) to the left hemi-face then the ,right side cream' labelled 1% pimecrolimus cream (Elidel; Novartis Pharma, Nuremberg, Germany) to the right hemi-face, twice daily. They were informed to apply a standard amount of each cream with the fingertip-unit and not allowed to use any other agent concomittantly other than sunblock. Clinical evaluation and subjective severity assessment were obtained along with photographic documentation at baseline, first, second, and fourth weeks of the therapy and at the follow-up visit. Rosacea severity score for each sign of erythema, papules, pustules, oedema, and telengiectesia were graded from 0 to 3. Patients were questioned for the subjective symptoms, overall improvement on appearance and side-effects. Results, Twenty-four patients completed the study with an exceptional compliance and tolerable safety profile. One patient withdrew from the study due to severe flare-up reaction affecting both hemi-faces. The mean baseline total rosacea severity scores were 5.06 + 1.29 for both sides and reduced to 2.5 ± 1.06 vs. 3.25 ± 1.24 on pimecrolimus vs. placebo applied sides without the significance (P = 0.06). There was not any significant difference concerning each rosacea sign scores and total rosacea severity scores except for the significant improvement in erythema score and total rosacea severity score obtained on the pimecrolimus-applied hemi-face at 2nd week of therapy (P =0.01 and P = 0.03, respectively). The reduction rates of the mean subjective severity scores at 4th week were 49.77% vs. 38.89% for pimecrolimus vs. placebo, respectively, without a statistical significance (P = 0.15). Subjective symptoms responded well in 54.16% of patients concerning pimecrolimus application compared with 12.50% for the placebo application. The side-effects were mostly transient local irritations. Conclusion, Our data implicated that pimecrolimus cream is not superior to placebo except for its efficacy on erythema. We believe that pimecrolimus cream can be a treatment option for rosacea patients with high erythema score for whom an initial accelerated improvement is needed. We believe further studies with topical pimecrolimus cream on larger study groups with different subtypes and severity of rosacea will clarify the potential effect of pimecrolimus cream for the treatment of rosacea. [source] Rosacea and its management: an overviewJOURNAL OF THE EUROPEAN ACADEMY OF DERMATOLOGY & VENEREOLOGY, Issue 3 2005AK Gupta ABSTRACT Background, Rosacea is a chronic inflammatory disorder that affects 10% of the population. The prevalence of rosacea is highest among fair-skinned individuals, particularly those of Celtic and northern European descent. Since a cure for rosacea does not yet exist, management and treatment regimens are designed to suppress the inflammatory lesions, erythema, and to a lesser extent, the telangiectasia involved with rosacea. Objectives, This review outlines the treatment options that are available to patients with rosacea. Methods, Published literature involving the treatment or management of rosacea was examined and summarized. Results, Patients who find that they blush and flush frequently, or have a family history of rosacea are advised to avoid the physiological and environmental stimuli that can cause increased facial redness. Topical agents such as metronidazole, azelaic acid cream or sulfur preparations are effective in managing rosacea. Patients who have progressed to erythematotelangiectatic and papulopustular rosacea may benefit from the use of an oral antibiotic, such as tetracycline, and in severe or recalcitrant cases, isotretinoin to bring the rosacea flare-up under control. Treatment with a topical agent, such as metronidazole, may help maintain remission. Patients with ocular involvement may benefit from a long-term course of an antibiotic and the use of metronidazole gel. A surgical alternative, laser therapy, is recommended for the treatment of telangiectasias and rhinophyma. Patients with distraught feelings due to their rosacea may consider cosmetic camouflage to cover the signs of rosacea. Conclusions, With the wide variety of oral and topical agents available for the effective management of rosacea, patients no longer need to feel self-conscious because of their disorder. [source] GSTM1 and GSTT1 null genotypes as possible heritable factors of rosaceaPHOTODERMATOLOGY, PHOTOIMMUNOLOGY & PHOTOMEDICINE, Issue 4 2006Ayca Cordan Yazici Purpose: Rosacea might be related to an increased activity of reactive oxygen species (ROS) and deficient function of the antioxidant system. Glutathione S-transferases (GSTs) play a primer role in cellular defense against electrophilic chemical species and radical oxygen species. We hypothesized that increased ROS activity or decreased antioxidant potential, possibly induced by GST gene polymorphism, might have a pathogenic role in rosacea. Methods: The study group consisted of 45 patients with rosacea and 100 control subjects. DNA samples were isolated from blood samples using high pure polymerase chain reaction (PCR) Template preparation Kit. The GSTM1, GSTT1, and P1 polymorphisms were detected using a real-time PCR and fluorescence resonance energy transfer with a Light-Cycler Instrument. Associations between specific genotypes and the development of rosacea were examined using logistic regression analyses to calculate odds ratios (OR) and 95% confidence intervals (CI). Results: GSTM1 and GSTT1 null genotypes were found to be statistically different from control (P=0.005, P=0.009, respectively), and associated with an increased risk of rosacea (OR [95% CI]: 2.84 [1.37,5.89]; OR [95% CI]: 2.68 [1.27,5.67], respectively). There was a statistically significant relationship between both null combination of the GSTM1 and GSTT1 genotype polymorphisms and rosacea (P=0.003, OR [95% CI]: 4.18 [1.57,11.13]). There were no statistically significant differences between patient and control groups for the GSTP1 Ile/Ile, Ile/Val, and Val/Val genotypes (P>0.05). Conclusion: We demonstrated a significant association between the GSTT1 and/or GSTM1 null genotypes and rosacea. However, the potential role of GSTs as markers of susceptibility to rosacea needs further studies in larger patient groups. [source] Risk factors for sebaceous gland diseases and their relationship to gastrointestinal dysfunction in Han adolescentsTHE JOURNAL OF DERMATOLOGY, Issue 9 2008Hong ZHANG ABSTRACT Sebaceous gland diseases are a group of common dermatological diseases with multiple causes. To date, a systematic report of the risk factors for sebaceous gland diseases in adolescents has not been published. The aim of this study was to assess the prevalence and risk factors for certain sebaceous gland diseases (seborrhea, seborrheic dermatitis, acne, androgenetic alopecia and rosacea) and their relationship to gastrointestinal dysfunction in adolescents. From August,October, 2002,2005, a questionnaire survey was carried out to obtain epidemiological data about sebaceous gland diseases. Using random cluster sampling, 13 215 Han adolescents aged 12,20 years were recruited from four countries or districts (Macau; Guangzhou, China; Malaysia; and Indonesia). The statistical software SPSS ver. 13.0 was used to analyze the data. The prevalence of seborrhea, seborrheic dermatitis, acne, androgenetic alopecia and rosacea was 28.27%, 10.17%, 51.03%, 1.65% and 0.97%, respectively. Based on multivariate logistic regression analysis, the risk factors for sebaceous gland diseases included: age; duration of local residency; halitosis; gastric reflux; abdominal bloating; constipation; sweet food; spicy food; family history of acne; late night sleeping on a daily basis; excessive axillary, body and facial hair; excessive periareolar hair; and anxiety. There was a statistically significant difference in the prevalence of gastrointestinal symptoms (halitosis; gastric reflux; abdominal bloating; constipation) between patients with and without sebaceous gland diseases (,2 = 150.743; P = 0.000). Gastrointestinal dysfunction is an important risk factor for diseases of the sebaceous glands and is correlated with their occurrence and development. [source] Morphological development and growth patterns of the leopard grouper Mycteroperca rosacea during larval developmentAQUACULTURE RESEARCH, Issue 1 2009Roberto Martínez-Lagos Abstract At 25 °C, metamorphosis in leopard grouper Mycteroperca rosacea larvae took 60 days after hatching. The total length at day 1 was 1.95±0.22 mm and juveniles reached a length of 30.64±0.23 mm at day 60; the increase was approximately linear. We describe eight stages of development during this period. Larvae with the yolk sac attached occur from days 1 to 4 (Stages 1 and 2). The preflexion occurs on days 5,20 (Stages 3 and 4). Bending notochord occurred at day 25 (Stage 5). The other morphological changes that precede the juvenile phase occurred progressively until day 60 (Stages 6,8). Allometric growth in the height and length of the head, trunk length, height and length of the tail and the diameter of the eye compared with the total length showed two distinct stages of growth. Inflexion point, where growth is positive, occurred when larvae reached between 18.75 and 21.59 mm, which corresponds to larvae at days 35,40. [source] Childhood ocular rosacea: Considerations for diagnosis and treatmentAUSTRALASIAN JOURNAL OF DERMATOLOGY, Issue 4 2009Esther Hong ABSTRACT Rosacea in children is not as well described as it is in adults. Ocular signs may be a dominant feature and some children with what has previously been called periorificial dermatitis may in fact have rosacea. We report three cases of paediatric ocular rosacea responding to prolonged treatment with oral erythromycin. Our cases demonstrate the close association of periorificial dermatitis with childhood rosacea, and highlight the importance of eye signs in its diagnostic criteria. [source] Prospective study to assess general practitioners' dermatological diagnostic skills in a referral settingAUSTRALASIAN JOURNAL OF DERMATOLOGY, Issue 2 2007Gilberto Moreno SUMMARY A prospective study was conducted to assess general practitioners' diagnostic skills in a referral setting. The primary objective was to identify general practitioners' strengths and weaknesses in diagnosing a broad spectrum of skin conditions. The diagnoses of 315 skin conditions made by 165 general practitioners were compared with a reference standard. The reference standard was made up of 73 histopathological diagnoses, 119 dermatologists' clinical diagnoses and 123 dermatologists' diagnoses plus follow up. The diagnoses assigned by referring general practitioners were consistent with dermatologists' clinical diagnoses and histology (where available) in 57% of cases. General practitioners made the correct diagnosis in 44% of cases when compared with histopathology. General practitioners were generally good at diagnosing conditions such as acne, warts, rosacea, molluscum contagiosum, vitiligo and skin tags. The proportion of correct diagnoses for premalignant and malignant skin tumours was 47%, and that of skin rashes requiring a diagnosis was 44%. Further education of general practitioners would help to improve their diagnostic skills in certain skin conditions. [source] Rosacea lymphoedema of the eyelidACTA OPHTHALMOLOGICA, Issue 6 2004Tze Foon Lai Abstract. Purpose:,To present a patient with rosacea lymphoedema of one upper eyelid resulting in unilateral complete ptosis. Methods:,A 51-year-old white man presented with a 12-month history of progressive painless swelling of the left upper eyelid. An incisional biopsy of the upper eyelid was performed. Results:,The biopsy showed dermal oedema with lymphangiectasia and telangiectasia, accompanied by a mild to moderate mixed chronic inflammatory infiltrate of lymphocytes, histiocytes, plasma cells and rare eosinophils. Stains for fungi and mycobacteria were negative. The lack of lichenoid reaction, dermal mucin or lip swelling indicated a lymphoedematous manifestation of rosacea. The patient was treated with minocycline and prednisolone with no effect. Conclusion:,Rosacea lymphoedema involving the eyelid, as in our case, is a rare complication and can present diagnostic and therapeutic challenges to the ophthalmologist. [source] |
