Background Although psoriasis is considered to have a “dual peak” in age of onset, currently no studies exist regarding the incidence of psoriasis in children. Objective The objective of this study is to determine the incidence of psoriasis in childhood. Methods A population-based incidence cohort of children aged <18 years first diagnosed with psoriasis between January 1, 1970 and December 31,1999 was assembled. The complete medical record of each child was reviewed and psoriasis diagnosis was validated by a confirmatory diagnosis in the medical record by a dermatologist or medical record review by a dermatologist. Age- and sex-specific incidence rates were calculated and were age- and sex-adjusted to 2000 U.S. white population. Results The overall age and sex adjusted annual incidence of pediatric psoriasis was 40.8 per 100,000 (95% confidence interval 1: 36.6, 45.1). When psoriasis diagnosis was restricted to dermatologist confirmed subjects in the medical record, the incidence was 33.2 per 100,000 (95% CI: 29.3, 37.0). Incidence of psoriasis in children increased significantly over time from 29.6 per 100,000 in 1970 to 1974 to 62.7 per 100,000 in 1995-1999 (p<0.001). Chronic plaque psoriasis was the most common type (73.7%), and the most commonly involved sites were the extremities (59.9%) and the scalp (46.8%). Limitations The population studied was a mostly Caucasian population in the upper Midwest. Conclusion The incidence of pediatric psoriasis increases with increasing age. There is no apparent “dual-peak” in incidence. The incidence of pediatric psoriasis increased in recent years in both boys and girls.

Background:The skin is an organ of communication and plays an important role in socialization. Skin is an organ that reacts directly upon emotional stimuli. The relationship between the 'skin' and the 'mind' is complex and of clinical importance. Aims: Assessing cutaneous disorders in patients with primary psychiatric conditions. Methods: One hundred patients with a primary psychiatric condition who had cutaneous disease were entered into the study group. The patients were classified appropriately based on the classification of psychocutaneous disorders. The control group included 100 patients presenting with a skin disorder and without any known psychiatric complaint. Results: In our study group there were 49 males and 51 females, Most of the cases and control group were in 2nd to 5th decade. The primary psychiatric condition in our study were Major depressive Disorder (44%), schizophrenia (31%), Anxiety disorder (18%), Bipolar Disorder (7%). In our study group we found 34% of the patient had Dermatophyte infection followed by the Bacterial infection (27%). Acne vulgaris (12%), parasitic infection like scabies seen in 11% of the study group, eczemas seen in 5% of the patients followed by pigmentary disorder (5%), papulosquamous like psoriasis seen in 4% and Hansen's in 2% of the patients. Conclusion: A statistically significant higher incidence of dermatophyte infections, Acne Vulgaris and Parasitic infections was seen in the study group.

“…Mazzetti et al [30]interviewed 80 in-patients and discerned a triggering event in 89% of cases, underlining the importance of the meaning of the event for the individual rather than the ‘objective’ intensity of the event. In a study of 245 psoriatic children, a worsening in relation to psychological stress was reported in 90% of cases [31]. Another finding that suggests a relationship between severe emotional stress and psoriasis is the observation of a positive correlation between the number of new cases of psoriasis in men referred to skin clinics and the level of civil war violence over a period of 11 years [32].…”

The possibility of a causal influence of emotional stress, especially of stressful life events, on the course of various skin diseases has long been postulated. Clinical wisdom and experience, as well as many anecdotal observations and uncontrolled case series, support this opinion. We reviewed the available evidence on the role of stressful life events in triggering or exacerbating skin diseases. The role of stressful events in vitiligo, lichen planus, acne, pemphigus and seborrhoeic dermatitis was either controversial or insufficiently explored. The role of stressful events in psoriasis, alopecia areata, atopic dermatitis and urticaria was apparently clearer. However, only a few studies met acceptable methodological standards for stress measurement. Also, few studies considered common potential confounding factors (e.g. age, duration of illness, familial factors), and no study controlled adequately for the influence of other crucial factors (e.g. discontinuation of treatment, seasonal effects). Adding that the large majority of studies were retrospective, it seems wise to conclude that only preliminary evidence has been published so far on the role of stressful life events in bringing on or worsening any dermatological disease. Further research is mandatory, either in the form of prospective studies or, more feasibly, of well-designed case-control studies with adequate statistical power. Future studies should also pay more attention to protective as well as vulnerability factors in stressful events. Further, it would be important to investigate other sources of psychological stress, such as chronic stress and everyday stress. Measuring stress appraisal, although difficult, would also be important.
