Intertrigo is an inflammatory dermatosis involving the body folds. Predisposing factors include constant friction opposing skin surfaces, obesity, sweating and occlusion. Colonization with bacteria, yeast and dermatophytes may exacerbate the dermatosis. Irritant antiseptics may aggravate intertrigo and provoke an allergic contact dermatitis. Treatment consists in careful drying the skin. Antimicrobial agents topically applied may be helpful. Predisposing factors should be corrected carefully.

A large family is reported in which at least four males are, or have been, affected with an unusual form of mental retardation associated with short stature, obesity, hypogonadism and skin disease. Investigations in the proband indicate that the hypogonadism is primary rather than secondary, and that the skin involvement is ichthyosiform. The mode of inheritance is entirely consistent with sex-linkage.

Psoriasis is a complex, multifactorial chronic skin disease. As in other chronic disorders, various lifestyle factors have been associated with its morbidity. We have pointed to the significance of the patient's lifestyle practices as they relate to psoriasis outcome. Several reports in the literature suggest that exogenous and endogenous factors, including emotional stress, alcohol use, smoking, and obesity, may have deleterious effects on the increased morbidity of psoriasis. In this study, we carried out a comprehensive evaluation to assess the effects of stress, alcohol use, smoking, obesity, and exercise on the natural history of psoriasis.

Acanthosis nigricans (AN) occurs associated with many different systemic diseases, such as endocrine disorders and internal malignant neoplasms. To our knowledge, the association of AN with severe atopic dermatitis (AD) or Down syndrome has not been described before. This 82-month retrospective study included 1038 patients: AN was present in 4.9% of atopic patients and 50.9% of subjects with Down syndrome. AN was more frequent in patients with severe AD and in 100% of cases of hand dermatitis and juvenile plantar dermatosis, located on the interphalangeal and metacarpophalangeal joints, whereas in Down syndrome other flexures were also affected. The pathogenesis of AN in AD is unknown, but in Down syndrome it seems to be related to obesity. Possible insulin resistance underlyng the pathogenesis of AN in these patients is still unknown.

Psoriasis is a frequent skin disease, affecting 2% of the world's population. Stress, alcohol, smoking and obesity may be associated with psoriasis. A 56-year-old man with BMI 46.9 kg/m(2), hypertension and gastroesophageal reflux, had severe psoriasis for the last 39 years, without any remission on multiple treatments. Psoriatic papules and plaques were noted on his face, dorsum of hands, buttocks, knees, and elbows. He underwent open Roux-en-Y gastric bypass. At 4-month follow-up, the patient had lost 23 kg or 34.8% of excess weight, and presented complete remission of the psoriasis without medications. Bariatric surgery for positive metabolic, psychological and lifestyle consequences should be considered a treatment of psoriasis. Long-term observation is necessary.

Psoriasis is a chronic inflammatory skin disease that is associated with an increased cardiovascular risk profile. The systemic inflammation present in psoriasis, various systemic treatments for psoriasis and an increased prevalence of unhealthy life style factors may all contribute to this unfavorable risk profile. The purpose of this article is to provide an overview of what is known about these risk factors in psoriasis, the way they influence the cardiovascular risk of psoriasis patients, and what can be done to reduce this risk. Genetic studies demonstrate that psoriasis and cardiovascular disease share common pathogenic features in which, for example inflammatory cytokines like TNF-alpha and IL-1 play an important role. The chronic inflammation in psoriasis has an unfavorable effect on the cardiovascular risk profile. Multiple cardiovascular risk factors seem to be influenced; the blood pressure, oxidative stress, dyslipidemia, endothelial cell dysfunction, homocysteine levels and blood platelet adhesion. Moreover, classic cardiovascular risk factors like smoking and obesity that have an increased prevalence among patients with psoriasis, indirectly also worsen the cardiovascular risk profile by stimulating the psoriasis activity. Systemic treatments in psoriasis reduce the cardiovascular risk by diminishing the inflammation, but it should be taken into account that most therapies also have adverse cardiovascular effects like dyslipidemia, hyperhomocysteinemia and hypertension. As a consequence preventive measures may be indicated at least during long-term treatments. Prospective research is warranted to accurately estimate the increased cardiovascular risk in psoriasis, to determine the underlying processes and to consider preventive measures according to the absolute risk of cardiovascular disease. The present overview provides data to advice health care providers to pay more attention to the cardiovascular risk profile in psoriasis patients.

The role of chronic inflammation causing metabolic and vascular disorders is increasingly recognized. It is hypothesized that proinflammatory cytokines contribute to atherogenesis, peripheral insulin resistance, and the development of hypertension and type II diabetes. Psoriasis as a chronic inflammatory skin disorder is characterized by a variety of immunologic and inflammatory changes and may similarly predispose for those disorders. The objective of this study was to elucidate the association of psoriasis with chronic vascular and metabolic disorders. We investigated a total of 581 adult patients hospitalised for plaque type psoriasis as compared to 1,044 hospital-based controls. A distinct pattern of chronic disorders was found to be significantly associated with psoriasis, including diabetes mellitus type II [odds ratio (OR)=2.48], arterial hypertension (OR = 3.27), hyperlipidemia (OR = 2.09), and coronary heart disease (OR = 1.95). The combined presence of these conditions together with obesity, known as the metabolic syndrome, was clearly more prevalent in psoriasis patients (OR = 5.29). In addition, psoriasis patients were significantly more likely to be smokers (OR = 2.96) and to have a regular or heavy consumption of alcohol (OR = 3.33 and 3.61, respectively). In conclusion, psoriasis patients appear to be at higher risk for diabetes mellitus and cardiovascular disease. This could likely be due to the effects of chronic inflammatory changes, in particular the secretion of proinflammatory cytokines. The risk of late term cardiovascular complications might support the use of systemic treatment in psoriasis.

Chronic plaque psoriasis is an immune-mediated, inflammatory skin disease with a heavy burden on quality of life of patients. The disease has a chronic relapsing course and may be life long. Comorbid disorders include psoriatic arthritis, obesity, dyslipidemia, hypertension and an increased rate of cardiovascular disease. Conventional systemic treatments include methotrexate, cyclosporine and acitretin, which are associated with end organ toxicity that precludes long term therapy. Biological drugs are designed to selectively interfere with the immune mechanisms that induce psoriasis. Efalizumab is effective for skin psoriasis but not psoriatic arthritis. Anti-TNF-alpha agents (etanercept, infliximab and adalimumab) are active on both psoriasis and psoriatic arthritis. Infliximab is the most effective and rapid agent, but its safety profile may be less favourable. Moreover, efficacy can reduce over time. Etanercept is moderately active but has a better safety profile, and can be discontinued and re-used without loss of efficacy. The long term safety of all these agents has not been established.

Acne inversa is a chronic inflammatory skin disease featuring cutaneous and subcutaneous nodular inflammation, fistula formation and discharge of foul-smelling secretions. The disease can lead to functional impairment and psychological problems. There is inflammation of the terminal hair follicles in intertriginous regions, especially perianal, axillary and inguinal areas. Less often there is submammary, periumbilical, retroauricular or nuchal involvement. Without treatment the disease is chronic and progressive. The causes of acne inversa are multifactorial and pathogenesis is still not well understood. Besides a positive family history, obesity and cigarette smoking are trigger factors. Early diagnosis and therapy of acne inversa saves the patient years of suffering. The most effective treatment is undoubtedly the radical wide excision of the affected areas. Local measures such as radiotherapy, photodynamic therapy and cryotherapy have provided little benefit; the same is true for systemic antibiotic treatment or hormonal therapy with anti-androgens. TNF-alpha antagonists seem to have a promising influence on the disease. Further studies investigating the effect of these substances on acne inversa are warranted.

The psoriasis is a chronic dermatosis which is characterized by strong inflammation. Recent studies showed that the chronic inflammation plays an important part in the pathogenesis of many metabolic and vascular diseases. Moreover, the diseases mediated by lymphocytes TH1 were related to the myocardial infarction. Epidemiologic investigations showed that psoriasis is associated at the increased risk of Comorbidities and mortality per comparison to the general population. Thus, the psoriatic patients have a high prevalence of metabolic pathologies such as the diabetes, hypertension, obesity and hyperlipidemy. These concomitant affections can complicate the treatment of psoriasis. It is important that the dermatologist systematically seeks these concomitant pathologies among psoriatic patients. These data also suggest that the treatments of these patients improve not only the skin lesions, but also control the inflammation associated with the psoriasis.
