RESUMO
BACKGROUND: Depression is a potential risk factor for mortality among the aged and it is also associated with other chronic diseases and unhealthy lifestyles that may also affect mortality. The purpose of this study was to investigate the association between depressive symptoms and mortality, controlling for health, nutritional status, and life-style factors. METHODS: A cohort of elderly people (N = 167) was followed-up for ten years. Information on socio-demographic characteristics, medical history, smoking, and alcohol consumption was collected. The primary outcome was all-cause mortality; the secondary outcome was cancer-specific mortality. The Geriatric Depression Scale (GDS-15) was used to assess depression. Using a multivariable Cox proportional hazards regression, we examined the association between depressive symptoms and mortality. RESULTS: Elderly people with depression (scoring above the depression cut-off of 7) had a 53% increased risk of mortality (relative risk (RR) 1.53; 95%CI: 1.05-2.24) compared to non-depressed subjects. The combination of depressive symptoms with smoking was associated with a particularly higher risk of mortality (RR: 2.61; 95%CI: 1.28-5.31), after controlling for potential confounders. CONCLUSIONS: Depressive symptoms are associated with a significantly increased risk of all-cause mortality. The combination of depressive symptoms and smoking shorten life expectancy among the aged.

The aim of this study was to explore the prevalence and characteristics of anniversary reactions (somatic symptoms occurring at the anniversary of specific events) in a large sample of 1498 medical patients from different medical settings who underwent the Structured Clinical Interview for DSM-IV (SCID) and the Structured Interview for Diagnostic Criteria for Psychosomatic Research (DCPR), which provide definition of anniversary reactions. In 54 (3.6%) of the 1498 patients for whom anniversary reaction was identified, 61.1% had a concurrent DSM-IV diagnosis. Other syndromes related to somatization, abnormal illness behavior, irritable mood, demoralization, and alexithymia were present in 9 of 10 cases. Symptoms of the conversion syndrome were found in 6 (0.4%) patients with the SCID and in 67 (4.5%) patients with the DCPR, 20% of whom also had anniversary reaction. The results should alert physicians to enquire about the timing of symptoms in relation to meaningful personal events.

Glutathione S-transferases (GSTs) are a family of enzymes that are known to play an important role in cellular protection against oxidative stress, including the oxidative stress caused by ultraviolet radiation. This study focused on the possible involvement of GSTM1 and GSTT1 polymorphisms in risk modulation of cutaneous melanoma. Within a case-control study, the presence of the null polymorphism at GSTM1 and GSTT1 was investigated in 188 cases of cutaneous melanoma and 152 controls. Information on socio-demographic characteristics, medical history, sun exposure and pigmentary characteristics were collected for all subjects. Logistic regression was used to estimate odds ratio (OR) and 95% confidence intervals (CI). An interaction was suggested between the GSTM1 and GSTT1 "null" genotype and episodes of sunburn in childhood OR of interaction (1.65, 95% CI (95% CI) 0.27-9.94). The risk of melanoma among the subset of participants who reported sunburns in childhood and who had both null variants, was nine (OR 9.16; 95% CI 1.18-70.9). The results suggest that subjects carrying both GSTM1 and GSTT1 null polymorphisms and experiencing sunburns in childhood have an extremely high risk of melanoma.

BACKGROUND: Cutaneous squamous cell carcinoma (SCC) is the second most frequent skin cancer among Caucasians. Advanced cases determine significant tissue destruction and they can metastasize. OBJECTIVES: To evaluate the role of GPs in timely diagnosis of SCC, examining the probability of delay before the diagnosis and treatment of SCC among patients having first seen a GP compared to patients having accessed directly a dermatologist. METHODS: We included a stratified sample of 308 SCC patients treated at a referral center in Italy. Medical records were reviewed and combined with patient interviews. RESULTS: Multivariable analysis has shown that patients who have first seen a GP have a significantly lower likelihood of long patient delay [odds ratio (OR) = 0.45; 95% confidence interval (95% CI) 0.21-0.94; P = 0.04) compared to patients having accessed directly a dermatologist. Treatment delay was not associated with the specialization of the first doctor seen for the lesion (OR = 0.52; 95% CI 0.15-1.84; P = 0.31). CONCLUSION: Our findings highlight the potential role of the GP in facilitating rapid access to appropriate health care.

Recent evidence suggests a relationship between psychoform and somatoform dissociation both in clinical and non clinical samples. The aim of the study was to investigate the association between the two forms of dissociation among 947 university students who completed two self-administered questionnaires, the Somatoform Dissociation Questionnaire (SDQ-20) and the Dissociative Experience Scale (DES). The main result of the study was that the association between somatoform and psychoform dissociation was strong for individuals with moderate level of DES scores (O.R.=7.0), but much stronger for individuals with high level of DES scores (O.R.=18.9).

Since the 20th century, psychogenic female sexual dysfunctions (FSD), like some somatoform and conversion disorders, have been considered an expression of somatoform dissociation. Several studies have reported dissociative symptoms in different somatoform and conversion disorders, but limited data are available on dissociation among patients with FSD. The aim of this study was to assess somatoform and psychoform dissociation among patients with women's orgasmic disorder, dyspareunia, and vaginismus. A battery of self-administered questionnaires (Somatoform Dissociation Questionnaire, Dissociative Experiences Scale, Hospital Anxiety and Depression Scale, Impact of Event Scale-Revised) was given to 200 gynecological outpatients to assess psychoform and somatoform dissociation and their association with FSD. A strong association between somatoform dissociation and FSD was observed (adjusted odds ratio [OR] = 5.39, 95% confidence interval [CI] = 1.15-25.32), the association between somatoform and psychoform dissociation being estimated by an adjusted OR of 4.83 (95% CI = 1.17-19.91). Our results are compatible with the idea that some forms of FSD could be regarded as somatoform dissociative disorders.

BACKGROUND: Large cutaneous squamous cell carcinoma (SCC) is associated with a higher risk of disfigurement, local recurrence, and metastasis; however, little is known about factors associated with tumor size at diagnosis. OBJECTIVES: We sought to evaluate factors associated with SCC size, including diagnostic/treatment delay and patient and tumor characteristics. METHODS: We studied a stratified sample of 308 patients with SCC recently treated at a dermatologic referral center in Italy. Medical records were reviewed and telephone interviews conducted. Multiple logistic regression was used to examine factors associated with SCC size. RESULTS: With univariate analyses, among both invasive and in situ cases, SCC greater than 2 cm was significantly associated with male gender, tumors arising in chronic lesions, and tumors located on not easily visible sites. Long delay before surgical removal was significantly associated with large SCC size only for invasive SCC (P < .001). Among patients with invasive SCC, when controlling for age and gender, multivariate analysis showed a significantly higher likelihood of SCC greater than 2 cm with a total delay longer than 18 months before surgical removal (odds ratio=4.18; 95% confidence interval 2.45-7.13) and for tumors arising in chronic lesions (odds ratio=6.42; 95% confidence interval 3.13-13.2). LIMITATIONS: The study was cross-sectional and based on a single center. CONCLUSIONS: Long total delay in removal significantly increased the likelihood of invasive SCC greater than 2 cm. Our findings highlight the importance of early detection and treatment to prevent large invasive SCCs, which are associated with a higher risk of disfigurement, recurrence, and metastasis. Particular attention should be paid to chronic skin lesions and not easily visible body sites during physician- and patient-performed examinations.

Advanced squamous cell carcinomas (SCC) of the skin can cause significant tissue destruction and may metastasize. Understanding the determinants of patient delay could help prevent advanced presentation. The purpose of the present study was to examine patient- and healthcare-related factors associated with delay before the detection and treatment of SCC. A sample of 308 patients with SCC treated at a dermatological referral centre in Italy were interviewed. Clinical data were obtained from the medical records. The highest quartile patients reported > 9 months delay between noticing the lesion and the first medical visit (defined as long patient delay). Multivariate analysis showed that SCC arising on pre-existing chronic lesions were associated with long patient delay (odds ratio = 3.17; 95% confidence interval 1.1-9.3). Controlling for confounders, the first physician's advice to remove the lesion immediately was associated with a shorter treatment delay (p < 0.001). In conclusion, our work emphasizes the importance of seeing a doctor about any change in a pre-existing lesion, particularly in light of the fact that SCC on chronic lesions are at greater risk of metastasis and recurrence.

AIMS: To evaluate skin cancer knowledge and preventive behaviors of patients recently treated for cutaneous squamous cell carcinoma (SCC) and to examine the factors associated with the adoption of preventive behaviors. METHODS: Telephone survey on 315 SCC patients treated at a large dermatological hospital in Italy, evaluating skin cancer knowledge, sun protection and skin examination practices as well as medical recommendations received after SCC removal. RESULTS: Skin cancer knowledge was fair/low for 48.9% of the participants. Doctors were the main source of skin cancer information for 24.4% of the patients. Of the patients assessed >or=12 months after SCC removal, 32.7% reported a total skin examination after removal. Of the participants, 41.6% never/rarely used sunscreens. In a multivariate analysis, the likelihood of having complete skin examinations was associated with a doctor's advice to have an examination (odds ratio, OR = 2.29; 95% confidence interval, CI = 1.2-4.4), a higher knowledge level (OR = 2.05; 95% CI = 1.1-3.8) and past skin examinations (OR = 3.62; 95% CI = 1.9-7.0). Doctor's recommendations increased the likelihood of adopting preventive behaviors. CONCLUSIONS: We found substantial knowledge gaps and limited adoption of skin cancer prevention, highlighting the need for interventions promoting knowledge and preventive behaviors, particularly among higher-risk patients.

Occupational pesticide exposure has been linked to cutaneous melanoma in epidemiological studies. We studied the association between cutaneous melanoma and the residential use of pesticides. This is a case-control study of cutaneous melanoma (287 incident cases; 299 controls). Data on pesticide use was obtained with a standardised interview. An increased risk of melanoma was found for high use (4 times annually) of indoor pesticides (odds ratio (OR)=2.18; 95% confidence intervals (CI) 1.07-4.43) compared to low use (1 times annually), after adjustment for sex, age, education, sun exposure and pigmentary characteristics. Subjects exposed for 10 years or more had two and a half times the risk (OR=2.46; 95% CI 1.23-4.94) of those exposed for less than 10 years. A dose response was observed for the intensity of pesticides use (p(trend)=0.027). The results indicate that residential pesticide exposure may be an independent risk factor for cutaneous melanoma.

BACKGROUND: Psoriasis is a chronic inflammatory skin disease in which several Th1 cytokines such as interleukin-1 beta (IL-beta) have been shown to play a pivotal role. Psychological stress has also been implicated in triggering or exacerbating the disease. METHODS: Salivary IL-1beta and cortisol levels of 25 patients with psoriasis were compared with those of 50 age- and sex-matched healthy controls under basal conditions and after a standardized stressful procedure including mental arithmetics and the Stroop Color-Word Naming Test. RESULTS: At baseline, mean IL-1beta levels were higher in patients with psoriasis than controls (p <0.001), whereas mean cortisol levels did not differ significantly between groups. Although IL-1beta levels increased after stress among controls, they did not increase among patients with psoriasis, with a significant group-by-time interaction (p <0.01). After stress, cortisol levels were significantly increased in both groups as compared with baseline (p < or =0.001), without any group-by-time interaction. Perceived stress was similar among psoriatic patients and controls. There was no significant correlation between changes in IL-1beta and changes in cortisol. CONCLUSIONS: The higher basal IL-1beta levels among psoriatic patients suggest that its production is increased. Changes in proinflammatory cytokine activity in psoriatic skin may play an important role in propagating inflammation. The blunted response of IL-1beta to stress observed in psoriatic patients may reflect a "ceiling effect", or be ascribed to a defective response of the immune system to adrenergic stimuli.

BACKGROUND: The tolerability and plasma absorption of gemcitabine administered at 40 mg/ml after small and extensive endoscopic transurethral resection of bladder tumors (TURB) were evaluated. PATIENTS AND METHODS: Nine patients with a history of recurrent superficial bladder cancer were eligible for a single immediate, post TURB, intravesical instillation of gemcitabine. The endoscopic resection was small in 5 patients and extensive in 4. The drug was administered at 40 mg/ml concentration (2000 mg in 50 ml saline) and held in the bladder for 1 hour. Plasma concentrations of gemcitabine and its metabolite (2',2'-difluorodeoxyuridine) were determined with a validated HPLC assay. The blood count and chemistry were performed one day and one week postoperatively. RESULTS: Toxicity was comparable for patients who underwent small or large TURB. The most significant side-effects were grade 2 vomiting and a transient grade 2 leukopenia after small and large TURB respectively. Mean maximum gemcitabine concentrations were 1.47 microg/ml in small TURB and 2.8 microg/ml in large TURB. The highest peak concentration of 4.26 microg/ml was found after extended bladder resection. CONCLUSION: A single, immediate postoperative, intravesical instillation of gemcitabine at high concentration is feasible with acceptable toxicity, and it may be considered as an option taking into account patient performance status, tumor characteristics and TURB extension.

OBJECTIVE: The relationship between alexithymia and psychosocial functioning has been investigated in a few studies using indirect measures of adaptation. We aimed at directly evaluating the relationship between alexithymia and global psychosocial functioning, as measured by a standardised scale. METHODS: A large, consecutive sample of dermatological inpatients (N=545) completed the 20-item Toronto Alexithymia Scale and the Skindex-29 and were administered the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition Axis I disorders and the Global Assessment of Functioning (GAF) scale. RESULTS: Multiple regression analysis was used to control for likely determinants of psychosocial functioning such as age, sex, education, burden of skin symptoms, and psychiatric morbidity. The GAF score was associated with psychiatric morbidity (beta=-.63, P<.001), alexithymia (in particular, the difficulty identifying feelings subscale) (beta=-.19, P<.001), and burden of skin symptoms (beta=-.07, P<.05). CONCLUSION: Given the well-known association between poor psychosocial functioning and several behavioural risk factors for health, our study may provide a further reason for clinicians to pay attention to alexithymic features among their patients.

A link between the mind and the skin has long been hypothesized. Indeed, some studies suggested that psychosocial factors may play a role in the pathogenesis and course of several skin diseases. Conversely, other studies suggested that psychiatric disorders and psychosocial difficulties may result as a complication of a primary skin disease. Epidemiological studies indeed found a high prevalence of psychiatric disorders among dermatological patients. This is a source of concern, because psychiatric morbidity is associated with emotional suffering, disability, lower quality of life, poorer adherence to dermatological treatment, and increased risk of self-harm. Conditions such as demoralization, health anxiety, irritable mood, type A behavior, and alexithymia were also found to be frequent in dermatological patients, and to be independently associated with greater psychological distress, lower quality of life, and poorer psychosocial functioning. Several studies also raised concerns about under-recognition and undertreatment of psychiatric disorders. This large body of findings suggests that psychosocial issues deserve more attention in everyday dermatological practice, and highlights the need for a biopsychosocial approach to the management of patients with skin disease. To this purpose, the development of efficient consultation-liaison services enabling an effective collaboration between dermatologists and mental health professionals is mandatory.

INTRODUCTION: Melanoma is an increasingly common malignancy of melanocytes, with incidence rates steadily rising over the past several decades. The objective of this study was to evaluate 5-year survival and to investigate the association between melanoma mortality and clinical and histological features. METHODS: We conducted a 5-year cohort study among 1020 patients from the same geographic area (Rome) with a single primary cutaneous melanoma diagnosed between January 1995 and December 2000. Survival probability was determined by Kaplan-Meier estimates, and prognostic factors were evaluated by multivariate analysis (Cox proportional hazards model). RESULTS: Survival decreased with increasing age (P for trend <0.049) and Breslow thickness (P for trend <0.0001). In the multivariate Cox model, Breslow thickness was the only independent prognostic factor for mortality in primary melanoma patients. The risk of death among patients with melanoma increased with increasing tumour thickness 0.76-1.49 mm (relative risk (RR) 2.67, 95% confidence interval (95% CI) 0.63-11.4); 1.50-4.0 mm (RR 6.38, 95% CI 1.75-23.2), >4.0 mm (RR 34.6, 95% CI 8.23-145.7) (P for trend <0.0001). The Years of Life Lost (YLLs) for the Breslow categories < or =0.75 mm, 0.76-1.49 mm, 1.50-4.0 mm and >4.0 mm were 65.4, 153.6, 274.3 and 317.6 years, respectively. CONCLUSION: This study shows the great importance of secondary melanoma prevention and illustrates how many years of life could be saved by early diagnosis.

BACKGROUND: Concerns have been raised about the potential of deliberate self-harm and suicide among patients with dermatologic conditions. OBJECTIVE: We sought to estimate the prevalence of suicidal ideation among patients with dermatologic conditions, and to identify demographic, clinical, and psychosocial correlates. METHODS: Two samples of outpatients with dermatologic conditions (N = 294) and inpatients (N = 172) completed the 12-item General Health Questionnaire, the Skindex-29, and the Patient Health Questionnaire. RESULTS: Forty patients (8.6%) reported suicidal ideation during the previous 2 weeks. In univariate analysis, the presence of suicidal ideation was associated with female sex, inpatient status, presence of a depressive or anxiety disorder, and higher 12-item General Health Questionnaire and Skindex-29 scores. The size of the diagnostic groups allowed reasonable prevalence estimates only for psoriasis (10%) and acne (7.1%). In multivariate analysis, only emotional distress (12-item General Health Questionnaire) and impaired social functioning (Skindex-29) were independently associated with suicidal ideation. LIMITATIONS: We lacked an observer-rated evaluation of skin condition and could rely only on the Skindex-29 symptoms subscale as a measure of disease severity. In addition, the measurement of suicidal ideation was limited as a result of the use of only one question to assess it. Furthermore, the cross-sectional design prevented causal inferences. CONCLUSION: Suicidal ideation is not rare among patients with dermatologic conditions. Assessing suicidality would be warranted in dermatologic practice among patients at particular risk such as women with high psychologic distress and impaired social functioning. The development of psychiatric consultation-liaison services is mandatory to provide effective treatment and careful follow-up of patients who are suicidal.

A systematic meta-analysis of observational studies of melanoma and one of the most important risk factors, the number of naevi, was conducted in order to clarify aspects of the aetiology of this disease. Following a systematic literature search, relative risks (RRs) were extracted from 46 studies published before September 2002. Dose-response random effects models were used to obtain pooled estimates. Sub-group analysis and meta-regression were carried out to explore sources of between-study variation and bias. Sensitivity analyses investigated the reliability of the results and any publication bias. Number of common naevi was confirmed an important risk factor with a substantially increased risk associated with the presence of 101-120 naevi compared with <15 (pooled Relative Risk (RR) = 6.89; 95% Confidential Interval (CI): 4.63, 10.25) as was the number of atypical naevi (RR = 6.36 95%; CI: 3.80, 10.33; for 5 versus 0). The type of study and source of cases and controls were two study characteristics that significantly influenced the estimates. Case-control studies, in particular when the hospital was the source for cases or controls, appeared to present much lower and more precise estimates than cohort studies.

A systematic revision of the literature was conducted in order to undertake a comprehensive meta-analysis of all published observational studies on melanoma. An extensive analysis of the inconsistencies and variability in the estimates was performed to provide some clues about its Epidemiology. Following a systematic literature search, relative risks (RRs) for sun exposure were extracted from 57 studies published before September 2002. Intermittent sun exposure and sunburn history were shown to play considerable roles as risk factors for melanoma, whereas a high occupational sun exposure seemed to be inversely associated to melanoma. The country of study and adjustment of the estimates adjuste for phenotype and photo-type were significantly associated with the variability of the intermittent sun exposure estimates (P = 0.024, 0.003 and 0.030, respectively). For chronic sun exposure, inclusion of controls with dermatological diseases and latitude resulted in significantly different data (P = 0.05 and 0.031, respectively). Latitude was also shown to be important (P = 0.031) for a history of sunburn; studies conducted at higher latitudes presented higher risks for a history of sunburns. Role of country, inclusion of controls with dermatological diseases and other study features seemed to suggest that "well conducted" studies supported the intermittent sun exposure hypothesis: a positive association for intermittent sun exposure and an inverse association with a high continuous pattern of sun exposure.

A systematic meta-analysis of observational studies of melanoma and family history, actinic damage and phenotypic factors was conducted as part of a comprehensive meta-analysis of all major risk factors for melanoma. Following a systematic literature search, relative risks were extracted from 60 studies published before September 2002. Fixed and random effects models were used to obtain pooled estimates for family history (RR = 1.74, 1.41-2.14), skin type (I vs. IV: RR = 2.09, 1.67-2.58), high density of freckles (RR = 2.10, 1.80-2.45), skin colour (Fair vs. Dark: RR = 2.06, 1.68-2.52), eye colour (Blue vs. Dark: RR = 1.47, 1.28-1.69) and hair colour (Red vs. Dark: RR = 3.64, 2.56-5.37), pre-malignant and skin cancer lesions (RR = 4.28, 2.80-6.55) and actinic damage indicators (RR = 2.02, 1.24-3.29). Sub-group analysis and meta-regression were carried out to explore sources of between-study variation and bias. Sensitivity analyses investigated reliability of results and publication bias. Latitude and adjustment for phenotype were two study characteristics that significantly influenced the estimates.

OBJECTIVE: To evaluate the association between different components of smoking history and the clinical severity of psoriasis. DESIGN: A hospital-based cross-sectional study. SETTING: Inpatient wards of a hospital for skin diseases in Rome, Italy. PATIENTS: A total of 818 adults with psoriasis. MAIN OUTCOME MEASURE: The Psoriasis Area and Severity Index was used to assess the clinical severity of psoriasis between February 21, 2000, and February 19, 2002. RESULTS: After adjustment for potential confounders (sex, age, body mass index, psychological distress, family history of psoriasis, duration of psoriasis disease, and alcohol consumption), high intensity of smoking (>20 cigarettes daily) vs a lower level of consumption (< or =10 cigarettes daily) was associated with a more than 2-fold increased risk of clinically more severe psoriasis (odds ratio [OR], 2.2; 95% confidence interval [CI], 1.2-4.1). Cigarette-years, measured as the product of the intensity and duration (years) of smoking, significantly increased the risk of clinically more severe psoriasis after adjustment for confounding factors (OR,1.3; 95% CI, 1.0-1.6, for a 600-U increase in cigarette-years). Separate analyses for men and women showed that the effect of cigarette-years was stronger for women (OR, 1.8; 95% CI, 1.2-2.6, for a 400-U increase in cigarette-years) than for men (OR, 1.2; 95% CI, 0.9-1.6, for a 700-U increase in cigarette-years). CONCLUSION: Smoking is associated with the clinical severity of psoriasis and highlights the importance of smoking cessation in patients with psoriasis.
