Psychiatric morbidity in dermatological outpatients: an issue to be recognized

Background There is a high prevalence of psychiatric disorders in dermatological outpatients. Objectives To estimate the magnitude of this problem and to identify a set of variables associated with the presence of psychiatric disorder. Methods All adults attending the outpatient clinics of a dermatological hospital on predetermined days were given a questionnaire comprising the Skindex‐29 and the 12‐item General Health Questionnaire (GHQ‐12). Results In total, 4268 questionnaires were given at admission, and 3125 were returned. Of these, 546 were blank or incomplete, leaving 2579 respondents (response rate 60·4%). Using a stringent cut‐off threshold (≥ 5) for psychiatric case identification with the GHQ‐12, scored in the conventional way, the overall prevalence of psychiatric morbidity was 25·2% (95% confidence interval 23·6–27·0%). We found a higher prevalence of psychiatric disorders in women and in widows/widowers, controlling for age. Health‐related quality of life was a much stronger predictor of psychiatric morbidity than physician‐rated clinical severity. High prevalence rates (> 30%) were observed among patients with acne, pruritus, urticaria, alopecia and herpesvirus infections, and in subjects without objective signs of dermatological disease. Conclusions Our study has depicted the situation that is actually faced by dermatologists in their everyday practice, where they are in a unique position to recognize psychiatric morbidity and to take appropriate measures. The GHQ‐12, being easy for patients to compile and for physicians or nurses to score, may be a practical tool to increase identification of patients with substantial psychological distress or formal psychiatric disorder in order to provide more comprehensive and appropriate intervention.

Stressful Life Events and Skin Diseases: Disentangling Evidence from Myth

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.

Mortality of intravenous drug users in Rome: a cohort study.

A historical cohort study was carried out in Rome to examine overall and cause-specific mortality among intravenous drug users (IVDUs). A total of 4200 IVDUs (3411 men and 789 women) enrolled in methadone treatment centers between 1980 and 1988 were studied. There were 239 deaths during the follow-up period. The overall SMR was 10.10 in the entire cohort (95% confidence interval, 8.86-11.47), 9.30 in males and 18.07 in females. A large excess of mortality in both sexes was found for infectious, circulatory, respiratory, and digestive diseases as well as for violence, overdose, AIDS, and unknown or ill-defined causes. Tumors and suicide were excessive only in males. Deaths due to drug overdose, violence or trauma, and cirrhosis accounted for 63.6%, AIDS for 7.1%, endocarditis and other bacterial infections for 7.1%, and neoplasms for 3.8% of total mortality. These findings document serious health consequences of drug abuse in Italy.

Factors associated with patient satisfaction with care among dermatological outpatients

Background It has been shown that poor patient satisfaction can lead to poor adherence to treatment with consequently poor health outcomes. In order to improve the quality of care perceived by the patient and thus the health outcome, it is important to understand which are the main factors influencing patient satisfaction.

Prevalence of symptoms experienced by patients with different clinical types of psoriasis

Background  The main dermatology textbooks describe only in passing pruritus in psoriasis and rarely mention other symptoms. A quantification of the presence of symptoms is not available for clinical subgroups of psoriasis.

Association between poorer quality of life and psychiatric morbidity in patients with different dermatological conditions

Objective: To determine the relationship between skin-related quality of life and psychiatric morbidity in patients with different skin conditions. Methods: We recruited all adults attending the outpatient clinics of the Dermatological Institute IDI-IRCCS, Rome, Italy, during 14 predetermined days. Eligible patients, who gave their informed consent, completed the Skindex-29 and the 12-item General Health Questionnaire (GHQ-12). We used a stringent cut-off threshold (≥5 on the GHQ-12) for identification of psychiatric morbidity. Skindex-29 scale scores were computed separately for GHQ noncases and GHQ cases. Results: A total of 2,136 patients were included in the analysis. For all skin conditions, GHQ cases had substantially poorer score in all 3 domains of quality of life, Symptoms, Emotions, and Functioning. Most differences remained significant after adjusting for clinical severity, age, sex, and education in multiple regression models. These differences were not as marked in the Symptoms scale for some conditions known to be nearly asymptomatic (eg, alopecia, vitiligo, nevi), suggesting that, although patients with psychiatric morbidity might be more burdened by their symptoms, nevertheless they do not perceive nonexistent symptoms. Conclusion: In most skin conditions we considered, psychiatric morbidity was strongly associated with poorer quality of life. Although the cross-sectional nature of our study does not allow identification of the direction of this association, care for the psychological condition of patients might have an impact on their quality of life.

Age, gender, quality of life and psychological distress in patients hospitalized with psoriasis

Background  Psoriasis has a great impact on the quality of life of patients, and the ageing population is an important public health issue.

Multicenter Study of the Association between Betapapillomavirus Infection and Cutaneous Squamous Cell Carcinoma

Human papillomaviruses (betaPV) from the beta genus cannot be classified according to their oncogenicity due to a paucity of information. This study evaluates the association between betaPV infection and cutaneous squamous cell carcinoma in conjunction with measures of UV exposure and susceptibility. We performed case-control studies in the Netherlands, Italy, and Australia, countries with profoundly different UV exposures. The presence of 25 betaPV types in eyebrow hair follicles was determined using a highly sensitive HPV DNA genotyping assay, and antibodies for the 15 most prevalent betaPV types in a total of 689 squamous cell carcinoma cases and 845 controls were detected using multiplex serology. Multivariate logistic regression models were used for case-control comparisons and interaction analyses. BetaPV DNA was detected in eyebrow hairs of more than 90% of all participants. The presence of betaPV DNA was associated with an increased risk of squamous cell carcinoma in the Netherlands (OR = 2.8; 95% CI 1.3-5.8) and Italy (OR = 1.7; 95% CI 0.79-3.6), but not in Australia (OR = 0.91; 95% CI 0.53-1.6). Seropositivity for betaPV in controls ranged between 52% and 67%. A positive antibody response against 4 or more betaPV types was associated with squamous cell carcinoma in Australia (OR = 2.2; 95% CI 1.4-3.3), the Netherlands (OR = 2.0; 95% CI 1.2-3.4) and fair-skinned Italians (OR = 1.6, 95% CI 0.94- 2.7). The association between UV susceptibility and squamous cell carcinoma was stronger in betaPV-seropositive people. These combined data support the hypothesis that betaPV may play a role in the development of cutaneous squamous cell carcinoma.

Measuring quality of life of patients with different clinical types of psoriasis using the SF‐36

Background  Different specific and generic instruments are used to evaluate quality of life in dermatology, but their interrelationship is not well known.

A case-control study of betapapillomavirus infection and cutaneous squamous cell carcinoma in organ transplant recipients

We examined the association between betapapillomavirus (betaPV) infection and cutaneous squamous cell carcinoma (SCC) in organ transplant recipients. A total of 210 organ transplant recipients with previous SCC and 394 controls without skin cancer were included. The presence of 25 betaPV types in plucked eyebrow hairs was determined using a human papillomavirus (HPV) DNA genotyping assay, and antibodies for the 15 most prevalent betaPV types were detected using multiplex serology. We used multivariate logistic regression models to estimate associations between various measures of betaPV infection and SCC. BetaPV DNA was highly prevalent (>94%) with multiple types frequently detected in both groups. We found a significant association between SCC and the concordant detection of both antibodies and DNA for at least one betaPV type (adjusted OR 1.6; 95% CI 1.1;2.5). A borderline‐significant association with SCC was found for HPV36 (adjusted OR 2.4; CI 1.0;5.4), with similar associations for HPV5, HPV9 and HPV24. These data provide further evidence of an association between betaPV infection and SCC in organ transplant recipients. Confirmation of a betaPV profile predictive of risk for SCC may pave the way for clinically relevant pretransplant HPV screening and the development of preventive and therapeutic HPV vaccination.
