“…Further evidence that seborrhoea is not essential to seborrhoeic dermatitis is provided by the observation that a dose of oestrogen sufficient to suppress sebum secretion produces no improvement in patients with seborrhoeic dermatitis. 9 Acne is associated with seborrhoea,10 and some clinicians believe that there is a high prevalence of seborrhoeic dermatitis among patients with acne, but we have been unable to find data to support this. Cohen3 found no association between the two disorders in his survey of 500 women, of whom 58 had seborrhoeic dermatitis and 146 clinical acne.…”

“…25,[33][34][35][36][37][38] SD has also been described as occurring exclusively on the side affected by paralysis in patients with CVA, following decompression for Chiari type-I malformation or in an area affected by syringomyelia. [38][39][40] In 1996, Ercis et al reported that 30.9% of individuals with Down syndrome had SD; however, Daneshpazhooh et al reported a prevalence of only 3%. 41,42 Other systemic diseases in which the incidence of SD is higher include acute myocardial infarction, alcoholic pancreatitis and alcoholism.…”

Seborrheic dermatitis is a chronic relapsing erythematous scaly skin disease, the prevalence of which is around 1 to 3% of the general population in the United States. It has two incidence peaks, the first in the first three months of life and the second beginning at puberty and reaching its apex at 40 to 60 years of age. The prevalence of seborrheic dermatitis is higher in HIV-positive individuals and the condition tends to be more intense and refractory to treatment in these patients. Neurological disorders and other chronic diseases are also associated with the onset of seborrheic dermatitis. The currently accepted theory on the pathogenesis of this disease advocates that yeast of Malassezia spp., present on the skin surface of susceptible individuals, leads to a non-immunogenic irritation due to the production of unsaturated fatty acids deposited on the skin surface. This article provides a review of the literature on seborrheic dermatitis, focusing on immunogenetics, the clinical forms of the disease and its treatment. . Keywords: Dermatitis; Dermatitis, seborrheic; Eczema Resumo: 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 áci-dos 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.

“…However, SD is common in patients with neurological disorders. Unilateral SD has been reported in a few cases such as meningioma, syringomyelia and facial nerve palsy, and bilateral or more generalized SD is seen in parkinsonism, post‐cerebrovascular events, epilepsy and central nervous system trauma . In some reports of seborrhea in parkinsonism, it is accepted as a sign of autonomic dysfunction; some authors attribute an increase of sebum excretion to the hyperactivity of the parasympathetic system in parkinsonism .…”

Although the role of autonomic nervous system in seborrheic dermatitis (SD) is still unclear, seborrhea is sometimes accepted as a sign of autonomic dysfunction in several nervous system diseases. Therefore, we aimed to investigate the sympathetic nervous system (SNS) activity in SD by recording sympathetic skin responses (SSR) from the scalp (S-SSR). Thirty-one control subjects and 22 SD patients were studied by evoking right and left S-SSR with electrical stimulation of the right median nerve at the wrist. Mean latencies and maximum amplitudes were calculated for both sides in each group. In seven out of 31 control subjects and in 13 out of 22 patients, the S-SSR could not be elicited on either side. There were four subjects with unilateral response in the patient group. There were significantly more non-responders among the patients with SD (P < 0.000). This study suggests that in SD, the autonomic nervous system may be involved. The S-SSR is a new site for recording SSR. The responses are relatively symmetrical and can be evoked easily by electrical stimulation, and may be used to evaluate the SNS function in SD patients and also in healthy subjects.
