Psoriatic lesions affecting the scalp, nails, palms, and the soles of the feet are described as difficult-to-treat psoriasis and require specific management. Involvement of these sites often has a significant physical and emotional impact on the patient and the lesions are difficult to control with topical treatments owing to inadequate penetration of active ingredients and the poor cosmetic characteristics of the vehicles used. Consequently, when difficult-to-treat sites are involved, psoriasis can be considered severe even though the lesions are not extensive. Scant information is available about the use of biologic therapy in this setting, and published data generally comes from clinical trials of patients who also had moderate to severe extensive lesions or from small case series and isolated case reports. In this article we review the quality of the scientific evidence for the 4 biologic agents currently available in Spain (infliximab, etanercept, adalimumab, and ustekinumab) and report level i evidence for the use of biologics to treat nail psoriasis (level of recommendation A) and a somewhat lower level of evidence in the case of scalp involvement and palmoplantar psoriasis.
Background: Previous clinical research has shown that severely ill (somatic) as well as many psychosomatic patients show raised noradrenaline (NA), adrenaline (AD), cortisol, free serotonin (f5HT) and platelet aggregability. Conversely, they show reduced NA/AD plasma ratio and platelet serotonin (p5HT). They also show adrenal hyperresponsiveness to an oral glucose load. These findings are opposed to those observed in depressed patients who show adrenal gland sympathetic hyporesponsiveness and neural sympathetic hyperactivity. Objective: To investigate adrenal gland and neural sympathetic systems as well as the other parameters in nondrepressed severely ill patients through the orthostasis exercise stress test which in normals triggers NA but no AD rise. Methods: We investigated 35 severely ill patients and their age- and sex-paired controls. Systolic, diastolic pulse pressure (PP), heart rate and neuroendocrine parameters were measured supine (0 min), at orthostasis (1 min) and exercise (5 min). A second test was performed 2 weeks later, after atropine injection. Multivariate analysis of variance, paired t test and Pearson product-moment test were employed. Results: The normal PP orthostasis fall was not observed in patients. At this period, an abnormal AD peak substituted the normal NA peak. The normal p5HT-f5HT orthostasis-exercise peaks were absent in patients. Cortisol and platelet aggregability were raised in patients. Conclusions: Severely ill (somatic) patients responded to the orthostasis-exercise stress test with adrenal and corticosuprarenal but not neural sympathetic activity. They did not show the normal parasympathetic activity at orthostasis. This adrenal gland sympathetic hyperactivity registered in somatic patients is similar to that observed in mammals which fail to cope with stress and contrary to the profile registered in depressed subjects who show NA but not AD rise.
Interstitial granulomatous dermatitis and arthritis (IGDA) is an uncommon clinicopathological condition that may occur in association with a number of systemic disorders. We present a novel case of IGDA in association with oesophageal squamous cell carcinoma (SCC). A 67-year-old man with a 3-month history of arthritis presented with several erythematous indurated plaques on his lateral trunk and arms. An oesophagogastroduodenoscopy showed an irregular mass 20 mm in size in the proximal third of the oesophagus, and on histopathological examination of a biopsy, the mass was identified as a poorly differentiated SCC. Histopathological examination of a skin biopsy found features consistent with interstitial granulomatous dermatitis. The combination of clinicopathological correlation and laboratory findings led to the diagnosis of IGDA. This association has not been previously described, to our knowledge.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
