    Özden, MG; Tekin, NS; Gürer, MA; Akdemir, D; Dogramaci, Ç; Utas, S; Akman, A; Evans, SE; Bahadir, S; Öztürkcan, S; Ikizoglu, G; Sendur, N; Köse, O; Bek, Y; Yayli, S; Cantürk, T; Turanl, AY
    To analyze the effect of possible risk factors, including breastfeeding, on the development of childhood-onset psoriasis, a multicenter case-control study with prospective collection of data was performed. Using a standard questionnaire, personal and specific variables including family history of psoriasis, maternal and environmental tobacco smoke exposure, body mass index (BMI), exclusive and partial breastfeeding for at least 3 and 12 months, cow's milk intake before 1 year, birth delivery method, and stressful life events were collected during 2009 from 537 patients with psoriasis and 511 controls younger than 18. Overall, patients more frequently reported exposure to environmental tobacco smoke at home and stressful life events in the year preceding the diagnosis than controls. The odds ratios (OR) for smoking and stressful life events were 2.90 (95% confidence interval [CI] = 2.27-3.78) and 2.94(95% CI = 2.28-3.79), respectively. In addition, children with psoriasis were more likely to have a higher BMI (>26) than controls (OR = 2.52; 95% CI = 1.42-4.49). High BMI, environmental tobacco smoke exposure at home, and stressful life events may influence the development of pediatric psoriasis.

    Yazici, O; Özdemir, N; Duran, AO; Menekse, S; Ali, M; Sendur, N; Karaca, H; Göksel, G; Arpaci, E; Hacibekiroglu, I; Bilgetekin, I; Kaçan, T; Özkan, M; Aksoy, S; Aksoy, A; Çokmert, S; Uysal, M; Elkiran, ET; Çiçin, I; Büyükberber, S; Zengin, N
    Aim: To investigate the role of surgical resection of primary tumor on overall survival (OS) in advanced gastric cancer patients at the time of diagnosis. Patients & methods: The survival rates of metastatic gastric cancer patients whose gastric primary tumor was resected at time of diagnosis were compared with metastatic gastric cancer patients whose primary tumor was nonresected. Results: The median progression-free survival and OS in operated and nonoperated group were 10 versus 6, 14 versus 9 months, respectively (p < 0.001). In multivariate analysis, gastric resection of primary tumor, Eastern Cooperative Oncology Group performance status, second-line chemotherapy had a significant effect on OS (hazard ratio [HR]: 0.52 [95% CI: 0.38-0.71], HR: 0.57 [95% CI: 0.42-0.78], HR: 1.48 [1.09-2.01]; p <= 0.001, p = 0.001 and p = 0.012, respectively). Conclusion: Subpopulations of patients with metastatic gastric cancer might benefit from surgical removal of primary tumor.

    Internalized stigma is the adoption of negative attitudes and stereotypes of the society regarding a person's illness. It causes decreased self-esteem and life-satisfaction, increased depression and suicidality, and difficulty in coping with the illness. The primary aim of this study was to investigate the internalized stigma state of psoriatic patients and to identify the factors influencing internalized stigma. The secondary aim was to identify the correlation of internalized stigma with quality of life and perceived health status. This multicentre, cross-sectional study comprised 1485 patients. There was a significant positive correlation between mean values of Psoriasis Internalized Stigma Scale (PISS) and Psoriasis Area and Severity Index, Body Surface Area, Dermatological Life Quality Index and General Health Questionnaire-12 (P < 0.001 in all). Lower percieved health score (P = 0.001), early onset psoriasis (P = 0.016), family history of psoriasis (P = 0.0034), being illiterate (P < 0.001) and lower income level (P < 0.001) were determinants of high PISS scores. Mean PISS values were higher in erythrodermic and generalized pustular psoriasis. Involvement of scalp, face, hand, genitalia and finger nails as well as arthropathic and inverse psoriasis were also related to significantly higher PISS scores (P = 0.001). Our findings imply that psoriatic patients experience high levels of internalized stigma which are associated with psoriasis severity, involvement of visible body parts, genital area, folds or joints, poorer quality of life, negative perceptions of general health and psychological illnesses. Therefore, internalized stigma may be one of the major factors responsible from psychosocial burden of the disease.

    Clinical characteristics, quality of life and risk factors for severity in palmoplantar pustulosis: a cross-sectional, multicentre study of 263 patients

    Background Palmoplantar pustulosis (PPP) is a rare, chronic, inflammatory skin disease characterized by sterile pustules on palmar or plantar areas. Data on PPP are scarce. Aim To investigate the clinical characteristics and risk factors for disease severity in a large cohort of Turkish patients with PPP. Methods We conducted a cross-sectional, multicentre study of patients with PPP recruited from 21 tertiary centres across Turkey. Results In total, 263 patients (165 women, 98 men) were evaluated. Most patients (75.6%) were former or current smokers. The mean Palmoplantar Pustulosis Area and Severity Index (PPPASI) was 8.70 +/- 8.06 and the mean Dermatology Life Quality Index (DLQI) score was 6.87 +/- 6.08, and these scores were significantly correlated (r = 0.52, P < 0.001). Regression analysis showed that current smoking was significantly associated with increased PPPASI (P = 0.03). Coexisting psoriasis vulgaris (PsV) was reported by 70 (26.6%) patients. Male sex prevalence, PPP onset incidence, disease duration, DLQI, and prevalence of nail involvement and psoriatic arthritis (PsA) were significantly increased among patients with PPP with PsV. Of the 263 patients, 18 (6.8%) had paradoxical PPP induced by biologic therapy, and these patients had significantly increased mean DLQI and prevalence of PsA (r = 0.03, P = 0.001). Conclusion Our data suggest that smoking is a risk factor for both PPP development and disease severity. Patients with PPP with PsV present distinct clinical features and patients with biologic therapy-induced paradoxical PPP have reduced quality of life and are more likely to have PsA.

    Internalized Stigma in Pediatric Psoriasis: A Comparative Multicenter Study
    Alpsoy, E; Polat, M; Yavuz, IH; Kartal, P; Balci, DD; Karadag, AS; Bilgic, A; Arca, E; Karaman, BF; Emre, S; Adisen, E; Sendur, N; Bilgic, O; Yazici, AC; Yalcin, B; Koca, R; Gunduz, K; Borlu, M; Ergun, T; Dursun, P; Bilgili, SG; Adanir, AS; Gulekon, A; Yagcioglu, G; Yilmaz, E; Kavuzlu, U; Senol, Y
    Background: Internalized stigma, adoption of negative attitudes and stereotypes of the society regarding persons' illness, has not been studied previously in pediatric psoriasis patients. Objective: We aimed to investigate the internalized stigma in pediatric psoriasis patients and to determine differences according to factors affecting internalized stigma compared to adult psoriasis patients. Methods: This multicenter, cross-sectional, comparative study included 125 pediatric (55 female, 70 male; mean age +/- standard deviation [SD], 14.59 +/- 2.87 years) and 1,235 adult psoriasis patients (577 female, 658 male; mean age +/- SD, 43.3 +/- 13.7 years). Psoriasis Internalized Stigma Scale (PISS), Dermatology Life Quality Index (DLQI), Perceived Health Status (PHS), and the General Health Questionnaire (GHQ)-12 were the scales used in the study. Results: The mean PISS was 58.48 +/- 14.9 in pediatric group. When PISS subscales of groups were compared, the pediatric group had significantly higher stigma resistance (p = 0.01) whereas adult group had higher scores of alienation (p = 0.01) and stereotype endorsement (p = 0.04). There was a strong correlation between mean values of PISS and DLQI (r = 0.423, p = 0.001). High internalized stigma scores had no relation to either the severity or localization of disease in pediatric group. However, poor PHS (p = 0.007) and low-income levels (p = 0.03) in both groups, and body mass index (r = 0.181, p = 0.04) in the pediatric group were related to high PISS scores. Conclusion: Internalized stigma in pediatric patients is as high as adults and is related to poor quality of life, general health, and psychological illnesses. Unlike adults, internalized stigma was mainly determined by psoriasis per se, rather than disease severity or involvement of visible body parts, genitalia or folds.
