Abstract
Facial seborrheic dermatitis (FSD) is a common facial inflammatory dermatitis. Needle-free transdermal jet injection (NTJI) is a non-invasive injection of drug solution by using a high-pressure liquid injection instrument. To explore a safer, more tolerable, and convenient medical way using NTJI in the treatment of FSD, the patients were treated with vitamin B6, glycyrrhizin compound, metronidazole, and hyaluronic acid sequentially using NTJI every 2 weeks, and only those treated for more than three times were included. A VISIA facial imaging system for the evaluation of erythema, superficial lipid level, and roughness of skin surface and a CK analyzer for biophysical parameters, including the stratum corneum hydration, facial surface lipid, and trans-epidermal water loss, were applied. Erythema was significantly reduced after every treatment (weeks 2, 4, and 6; P < 0.05), whereas superficial lipid level was not improved significantly until week 6 (P < 0.05), and roughness of the skin surface was not improved significantly during the whole treatment. The stratum corneum hydration of lesional skin was significantly increased after three times of treatment (P < 0.05). No observable adverse effect, such as marked erythema, blistering, or atrophy, was observed. Sequential transdermal delivery of small molecular weight drugs (vitamin B6, glycyrrhizin compound, metronidazole, and hyaluronic acid) using NTJI is a safe, low-toxicity, and take-home drug-free therapy for the treatment of FSD.

Abstract
Seborrheic dermatitis (SD) is a chronic, recurring inflammatory skin disorder that manifests as erythematous macules or plaques with varying levels of scaling associated with pruritus. The condition typically occurs as an inflammatory response to Malassezia species and tends to occur on seborrheic areas, such as the scalp, face, chest, back, axilla, and groin areas. SD treatment focuses on clearing signs of the disease; ameliorating associated symptoms, such as pruritus; and maintaining remission with long-term therapy. Since the primary underlying pathogenic mechanisms comprise Malassezia proliferation and inflammation, the most commonly used treatment is topical antifungal and anti-inflammatory agents. Other broadly used therapies include lithium gluconate/succinate, coal tar, salicylic acid, selenium sulfide, sodium sulfacetamide, glycerin, benzoyl peroxide, aloe vera, mud treatment, phototherapy, among others. Alternative therapies have also been reported, such as tea tree oil, Quassia amara, and Solanum chrysotrichum. Systemic therapy is reserved only for widespread lesions or in cases that are refractory to topical treatment. Thus, in this comprehensive review, we summarize the current knowledge on SD treatment and attempt to provide appropriate directions for future cases that dermatologists may face.

Abstract
BACKGROUND Seborrhoeic dermatitis is a chronic inflammatory skin condition that is distributed worldwide. It commonly affects the scalp, face and flexures of the body. Treatment options include antifungal drugs, steroids, calcineurin inhibitors, keratolytic agents and phototherapy. OBJECTIVES To assess the effects of antifungal agents for seborrhoeic dermatitis of the face and scalp in adolescents and adults.A secondary objective is to assess whether the same interventions are effective in the management of seborrhoeic dermatitis in patients with HIV/AIDS. SEARCH METHODS We searched the following databases up to December 2014: the Cochrane Skin Group Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL) (2014, Issue 11), MEDLINE (from 1946), EMBASE (from 1974) and Latin American Caribbean Health Sciences Literature (LILACS) (from 1982). We also searched trials registries and checked the bibliographies of published studies for further trials. SELECTION CRITERIA Randomised controlled trials of topical antifungals used for treatment of seborrhoeic dermatitis in adolescents and adults, with primary outcome measures of complete clearance of symptoms and improved quality of life. DATA COLLECTION AND ANALYSIS Review author pairs independently assessed eligibility for inclusion, extracted study data and assessed risk of bias of included studies. We performed fixed-effect meta-analysis for studies with low statistical heterogeneity and used a random-effects model when heterogeneity was high. MAIN RESULTS We included 51 studies with 9052 participants. Of these, 45 trials assessed treatment outcomes at five weeks or less after commencement of treatment, and six trials assessed outcomes over a longer time frame. We believe that 24 trials had some form of conflict of interest, such as funding by pharmaceutical companies.Among the included studies were 12 ketoconazole trials (N = 3253), 11 ciclopirox trials (N = 3029), two lithium trials (N = 141), two bifonazole trials (N = 136) and one clotrimazole trial (N = 126) that compared the effectiveness of these treatments versus placebo or vehicle. Nine ketoconazole trials (N = 632) and one miconazole trial (N = 47) compared these treatments versus steroids. Fourteen studies (N = 1541) compared one antifungal versus another or compared different doses or schedules of administration of the same agent versus one another. KetoconazoleTopical ketoconazole 2% treatment showed a 31% lower risk of failed clearance of rashes compared with placebo (risk ratio (RR) 0.69, 95% confidence interval (CI) 0.59 to 0.81, eight studies, low-quality evidence) at four weeks of follow-up, but the effect on side effects was uncertain because evidence was of very low quality (RR 0.97, 95% CI 0.58 to 1.64, six studies); heterogeneity between studies was substantial (I² = 74%). The median proportion of those who did not have clearance in the placebo groups was 69%.Ketoconazole treatment resulted in a remission rate similar to that of steroids (RR 1.17, 95% CI 0.95 to 1.44, six studies, low-quality evidence), but occurrence of side effects was 44% lower in the ketoconazole group than in the steroid group (RR 0.56, 95% CI 0.32 to 0.96, eight studies, moderate-quality evidence).Ketoconozale yielded a similar remission failure rate as ciclopirox (RR 1.09, 95% CI 0.95 to 1.26, three studies, low-quality evidence). Most comparisons between ketoconazole and other antifungals were based on single studies that showed comparability of treatment effects. CiclopiroxCiclopirox 1% led to a lower failed remission rate than placebo at four weeks of follow-up (RR 0.79, 95% CI 0.67 to 0.94, eight studies, moderate-quality evidence) with similar rates of side effects (RR 0.9, 95% CI 0.72 to 1.11, four studies, moderate-quality evidence). Other antifungalsClotrimazole and miconazole efficacies were comparable with those of steroids on short-term assessment in single studies.Treatment effects on individual symptoms were less clear and were inconsistent, possibly because of difficulties encountered in measuring these symptoms.Evidence was insufficient to conclude that dose or mode of delivery influenced treatment outcome. Only one study reported on treatment compliance. No study assessed quality of life. One study assessed the maximum rash-free period but provided insufficient data for analysis. One small study in patients with HIV compared the effect of lithium versus placebo on seborrhoeic dermatitis of the face, but treatment outcomes were similar. AUTHORS' CONCLUSIONS Ketoconazole and ciclopirox are more effective than placebo, but limited evidence suggests that either of these agents is more effective than any other agent within the same class. Very few studies have assessed symptom clearance for longer periods than four weeks. Ketoconazole produced findings similar to those of steroids, but side effects were fewer. Treatment effect on overall quality of life remains unknown. Better outcome measures, studies of better quality and better reporting are all needed to improve the evidence base for antifungals for seborrhoeic dermatitis.

Abstract
The majority of nonbacterial dermatological conditions treated with antibiotics benefit from the anti-inflammatory properties of these medications, usually dapsone or tetracycline. Many other antimicrobials are used to treat noninfectious conditions. The following chapter is an overview of select noninfectious dermatological conditions for which antibiotics are used, with a focus on the most common antibiotics used for their nonantimicrobial properties.

Abstract
A dermatite seborreica é uma doença eritêmato-escamativa de caráter crônico-recidivante que acomete entre 1 e 3% da população geral dos Estados Unidos. Possui dois picos de incidência - o primeiro, durante os três primeiros meses de vida, e o segundo, a partir da puberdade, atingindo seu ápice entre os 40 e 60 anos de idade. Os indivíduos HIV positivos têm maior prevalência da doença, que apresenta maior intensidade e tendência à refratariedade ao tratamento. Doenças neurológicas e outras doenças crônicas também estão associadas ao desenvolvimento da dermatite seborreica. Como mecanismo fisiopatogênico, reconhece-se que o fungo Malassezia sp., presente na pele de indivíduos suscetíveis, leve a uma irritação não-imunogênica a partir da produção de metabólitos à base de ácidos graxos insaturados deixados na superfície cutânea. Este artigo faz uma revisão da literatura sobre dermatite seborreica, com ênfase nos aspectos imunogenéticos, formas clínicas e tratamento.

Abstract
When discussing treatment options with patients, clinicians often use terms such as "frequently" or "rarely" when referring to potential benefits or possible harms. Quantitative measurements of treatment benefits and harms derived from randomized clinical trials or meta-analysis such as odds ratios or risk reduction are more precise terms, yet physicians and their patients find them difficult to understand and they are not, therefore, commonly used in clinical practice. To overcome the lack of intuitiveness for traditional measures of risk estimates derived from clinical trials, the number needed to treat (NNT) has been widely recommended as a measure of effectiveness, and number needed to harm as a way of describing risk of possible adverse events. NNT is simply the number of patients who, on average, would need to be treated with a proposed intervention to demonstrate one additional gain over the standard comparator intervention. NNT is an absolute measure and it is calculated as the inverse of the absolute risk reduction. In this article we describe the usefulness and limits of the NNT with particular reference to dermatology, and compare NNT with other relative measures such as the relative risk and relative risk reduction.

Abstract
BACKGROUND Recently, two placebo-controlled studies have shown that topical metronidazole was effective in the treatment of seborrheic dermatitis. OBJECTIVE To compare the efficacy and safety of metronidazole 0.75% gel with that of ketoconazole 2% cream in the treatment of facial seborrheic dermatitis. METHODS A total of 60 consecutive patients with facial seborrheic dermatitis were included. Patients were randomized into two groups. One group used ketoconazole 2% cream with metronidazole gel as vehicle; the other group used metronidazole 0.75% gel with ketoconazole cream as vehicle for a 4-week treatment period. Main outcome measures were change in clinical severity scores, patients' and investigator's global evaluation of improvement and frequency of side-effects. RESULTS All the assessments were made by an investigator who was unaware of which group the patients were allocated to. Mean percentage decrease in clinical severity scores from baseline to last available visit was 63.4% (95% CI 57.7-69) and 54.4% (95% CI 47.9-61) in the ketoconazole- and metronidazole-treated patients, respectively (P = 0.31). Eighty-two per cent of patients in the ketoconazole group vs. 79% of patients in the metronidazole group rated their global improvement as significant or moderate (P > 0.05). No statistically significant difference in the frequency of side-effects was detected between the two groups. The results of this study need to be confirmed in further studies involving large numbers of patients. CONCLUSION Our data demonstrated that metronidazole 0.75% gel had a comparable efficacy and safety profile with that of ketoconazole 2% cream in the treatment of facial seborrheic dermatitis.

Abstract
BACKGROUND Seborrheic dermatitis (SD) is a common, chronic dermatosis. Although the pathogenetic mechanisms of SD are not clear, Malassezia spp. yeasts are known to cause the disease. Previous studies have shown that topical and systemic antifungals provide clinical benefit. OBJECTIVE To evaluate the safety and efficacy of short-term oral fluconazole in patients with SD. METHODS Sixty-three patients with mild-to-moderate SD were randomly allocated to receive either oral fluconazole 300 mg in a single dose per week or placebo, for 2 weeks. Twenty-seven patients taking fluconazole and 23 patients taking placebo completed the study and were analyzed. The SD area severity index (SDASI) score and the patient's subjective assessment of pruritus and burning sensation were evaluated before and after treatment. Both the investigator and the patients were blinded to treatment. RESULTS A statistically significant improvement in SDASI score after treatment compared with baseline was obtained with fluconazole (p=0.01) but not with placebo. However, the difference between the treatment groups was not statistically significant (p>0.05). Subjective improvements in symptoms, such as pruritus and burning sensation, were observed in both groups but no statistically significant differences versus baseline were seen. CONCLUSION The results of this study indicate that fluconazole provides marginal and statistically insignificant benefit for the therapy of SD. However, larger studies using different dosages and/or durations of fluconazole therapy may provide a rationale for systemic use of fluconazole in SD.

Abstract
BACKGROUND African Americans with seborrheic dermatitis may manifest associated hypopigmenation. Corticosteroids and antifungals are often used for treatment, yet chronic use of corticosteroids may be associated with skin atrophy, increased intraocular pressure, or further hypopigmenation. Pimecrolimus has been used successfully in a few patients with seborrheic dermatitis. OBJECTIVES This open-label, pilot trial assessed the efficacy and tolerability of pimecrolimus in the treatment of seborrheic dermatitis in African Americans with hypopigmentation. METHODS Five African American adults with seborrheic dermatitis used a thin layer of pimecrolimus on the involved areas twice per day for 16 weeks. Clinical measures of improvement included erythema, scaling, and pruritus. Hypopigmentation was measured objectively using a mexameter. RESULTS All participants noted a marked decrease in the severity of their condition. An improvement in hypopigmentation was also noted. For all indicators, the magnitude of improvement was most marked during the initial 2 weeks of treatment. LIMITATIONS This was an open-label pilot trial limited to just 6 participants, only 5 of whom completed the study. CONCLUSIONS Topical pimecrolimus cream may be an excellent alternative therapeutic modality for treating seborrheic dermatitis in African Americans, particularly in those with associated hypopigmentation.

Abstract
Seborrhoeic dermatitis (SD) is a recurrent, chronic inflammation of the skin that occurs on sebum rich areas such as the face, scalp and chest, characterised by red scaly lesions. The are many studies indicating that Malassezia yeasts play an important role in the aetiology of this condition, most of the evidence for which comes from demonstrated responsiveness to treatment with antifungal agents. Its aetiology, however, is far from being resolved. Some believe that it is the immune response of the skin to the Malassezia that is the cause of the disease. Traditional treatments of SD have been the use of keratolytic agents or corticosteroids. Since the discovery of ketoconazole, a considerable amount of research has been focused on determining the efficacy of various antifungal agents. This article reviews clinical trial data on treatment options available for SD.

Abstract
Seborrheic dermatitis (SD) is a common dermatological disorder that varies greatly in severity between individuals and with time. The etiology of this disease is poorly understood. Early investigators focused on the role of Malassezia (previously Pityrosporum) yeasts in the development of SD. Some researchers have hypothesized that there is an immunological component to SD and that this disease is caused by an altered immune response to Malassezia yeasts. However, other researchers view this condition as the result of hyperproliferation. Both antifungal and anti-inflammatory preparations have been used to treat SD effectively and safely. The wide range of antifungal formulations available (creams, shampoos, oral drugs) provides safe, effective and flexible treatment options for SD.

Abstract
UNLABELLED Seborrheic dermatitis is a common inflammation of the skin, occurring most often on the face, scalp and chest. It is closely related to infantile seborrheic dermatitis, or diaper rash. Seborrheic dermatitis is particularly common in patients with Parkinson's disease or with HIV/AIDS. The recent resurgence of interest in Malassezia yeasts has revived the old hypothesis that seborrheic dermatitis is caused by an altered relationship between these skin commensals and the host. Moreover, the success of antifungal medications in treating seborrheic dermatitis provides new evidence for this view. LEARNING OBJECTIVE Upon completing this paper, the reader should be aware of the clinical presentation of seborrheic dermatitis and which populations are at particular risk of developing this disorder. In addition, s/he will be aware of the role of Malassezia yeasts in seborrheic dermatitis and the way in which knowledge of the importance of these yeasts has altered the treatment of this disorder.

Abstract
Seborrheic dermatitis is a superficial fungal disease of the skin, occurring in areas rich in sebaceous glands. It is thought that an association exists between Malassezia yeasts and seborrheic dermatitis. This may, in part, be due to an abnormal or inflammatory immune response to these yeasts. The azoles represent the largest class of antifungals used in the treatment of this disease to date. In addition to their antifungal properties, some azoles, including bifonazole, itraconazole, and ketoconazole, have demonstrated anti-inflammatory activity, which may be beneficial in alleviating symptoms. Other topical antifungal agents, such as the allylamines (terbinafine), benzylamines (butenafine), hydroxypyridones (ciclopirox), and immunomodulators (pimecrolimus and tacrolimus), have also been effective. In addition, recent studies have revealed that tea tree oil (Melaleuca oil), honey, and cinnamic acid have antifungal activity against Malassezia species, which may be of benefit in the treatment of seborrheic dermatitis. In cases where seborrheic dermatitis is widespread, the use of an oral therapy, such as ketoconazole, itraconazole, and terbinafine, may be preferred. Essentially, antifungal therapy reduces the number of yeasts on the skin, leading to an improvement in seborrheic dermatitis. With a wide availability of preparations, including creams, shampoos, and oral formulations, antifungal agents are safe and effective in the treatment of seborrheic dermatitis.

Abstract
BACKGROUND Due to the high rate of recurrence, seborrheic dermatitis (SD) represents a therapeutic problem. AIM To evaluate the role of oral itraconazole in the treatment of SD. PATIENTS AND METHODS Thirty-two patients with SD were enrolled in the study. All topical and oral treatments were stopped. The patients applied 1% hydrocortisone cream twice daily for 1 month. In addition, they took itraconazole, 200 mg/day, during the first week of the first month and then hydrocortisone cream was stopped and itraconazole (200 mg/day) was given on the first 2 days of the following 11 months. The patients were followed for 2 months without medicine. The severity score was measured at the initial evaluation, and at the first, 12th, and 14th months. RESULTS Twenty-eight patients completed the study. There was a statistically significant decrease in the mean severity score at the first, 12th, and 14th months. On the final evaluation at the 12th month, 19 of the 28 patients showed a complete improvement, and three patients showed a slight improvement. CONCLUSIONS This study indicates that itraconazole plays an important role in the treatment of SD.

Chosidow O, Maurette C, Dupuy P. Randomized, open-labeled, non-inferiority study between ciclopiroxolamine 1% cream and ketoconazole 2% foaming gel in mild to moderate facial seborrheic dermatitis. Dermatology 2003; 206:233-40. [PMID: 12673081 DOI: 10.1159/000068904] [Citation(s) in RCA: 32] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2002] [Accepted: 09/10/2002] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND Topical ketoconazole (KC) is considered a standard treatment for seborrheic dermatitis. In a placebo-controlled, double-blind clinical study, we demonstrated that antifungal ciclopiroxolamine (CIC) 1% cream was effective in mild to moderate facial seborrheic dermatitis. OBJECTIVES We report here the results of a randomized, open-labeled clinical study comparing CIC 1% cream and KC 2% foaming gel in patients with mild to moderate facial seborrheic dermatitis, using a non-inferiority trial design. METHODS Three hundred and three patients were enrolled, 154 patients in the CIC group and 149 patients in the KC group, and comprised the study population for intent-to-treat (ITT) analysis. The per protocol (PP) population comprised a total of 282 patients, 147 in the CIC group and 135 in the KC group. Patients were randomly allocated to apply either the CIC 1% cream twice a day for 28 days maximum (initial phase), followed by once a day for another 28 days (maintenance phase); or the KC 2% foaming gel twice a week at the initial phase, followed by once a week during the maintenance phase. Test lesions were defined as lesions localized to the nasolabial folds, alae nasi, and/or the eyebrows. The main efficacy parameter (endpoint) was the proportion of patients who presented a complete disappearance of both erythema and scaling on test lesions and pruritus on all lesions at the end of the initial phase (28 days or less). RESULTS At baseline, both treatment groups were comparable in terms of demographic data and lesional status. At the end of the initial phase, responders were found to be non-inferior with CIC treatment compared with KC treatment in both study populations (ITT population: 37% CIC responders and 34% KC responders; in the PP population: 39 and 36% responders, respectively). The 95% confidence interval limit for differences were -7.99-13.56 in the ITT population, and -8.06-14.5 in the PP population. At the end of the maintenance phase, treatment response to CIC was greater than to KC in both ITT and PP populations (57 and 44% in both populations, respectively, p = 0.03). Local tolerance as well as global acceptability was better with CIC than with KC (p = 0.001, intergroup analysis). CONCLUSION CIC 1% administered as a cream demonstrated to be non-inferior to KC 2% foaming gel in mild to moderate facial seborrheic dermatitis.

Abstract
BACKGROUND Seborrheic dermatitis is a common, chronic, papulosquamous dermatosis. Although several types of treatment have been developed, repetitive treatment courses are often necessary. AIM To perform a randomized, placebo-controlled, double-blind clinical study with metronidazole 0.75% gel in patients with mild to moderate seborrheic dermatitis of the face. METHODS Eighty-four patients (52 males and 32 females) with seborrheic dermatitis were enrolled in the study. Patients were randomly allocated to the application of metronidazole 0.75% gel or placebo to their facial lesions, twice daily for 8 weeks. Patients were scored with regard to the severity of the lesions at the initial evaluation and every 2 weeks for 2 months. All patients were evaluated for a final assessment of improvement at the end of the study. RESULTS At baseline, both treatment groups were comparable in terms of demographic data and lesion severity score. Seventy-eight patients (48 males and 30 females), 48 (62%) in the metronidazole group and 30 (38%) in the placebo group, completed the study. Two patients in the metronidazole group and four patients in the placebo group left the study. There was no statistically significant difference in the change in the mean severity score between the two groups at the end of the study (P > 0.05). At the final evaluation of the response at 8 weeks, no statistically significant difference was found between the treatment groups (P > 0.05). Metronidazole gel was generally tolerated well during the study. CONCLUSIONS Metronidazole 0.75% gel and placebo show similar efficacy in the treatment of seborrheic dermatitis.

Abstract
Seborrheic dermatitis is present in 1% to 3% of immunocompetent adults, and is more prevalent in men than in women. Seborrheic dermatitis may be seen in conjunction with other skin diseases, such as rosacea, blepharitis or ocular rosacea, and acne vulgaris. Malassezia yeasts have been associated with seborrheic dermatitis. Abnormal or inflammatory immune system reactions to these yeasts may be related to development of seborrheic dermatitis. Treatment modalities for seborrheic dermatitis include keratolytic agents, corticosteroids, and more recently, antifungal agents. Antifungal agents do not carry a risk of skin atrophy or telangiectasia with prolonged use, and it is more prudent to consider antifungals than corticosteroid preparations. The wide range of antifungal formulations available (creams, shampoos, or oral) provides safe, effective, and flexible treatment options for seborrheic dermatitis.

Abstract
We investigated the effects of 1-4% ointments of metronidazole and tinidazole (derivatives of nitroimidazole) on models of inflammatory dermatitis evoked by antigen, hapten and monoclonal anti-dinitrophenol (DNP) IgE antibody in mice. Metronidazole and tinidazole ointments (1) suppressed the late-phase reaction (LPR) of biphasic ear edema in mice sensitized with ovalbumin (OA), (2) suppressed trinitrochlorobenzene-induced inflammatory dermatitis, (3) suppressed the immediate phase reactions and LPR in mice passively sensitized with anti-DNP IgE mAb, and (4) enhanced vascular permeability and the number of scratching reactions, presumably due to itching, in passively sensitized mice. These results strongly indicate that metronidazole and tinidazole 1-4% ointments possess antiinflammatory, immunosuppressive and anti-itching effects, and have the potential for clinical use in the treatment of human inflammatory skin diseases including atopic dermatitis in addition to rosacea and acne vulgaris.
