This study was undertaken 6-7 months after the 1999 Athens earthquake with the aim of exploring the differences in post-traumatic stress disorder (PTSD), anxiety and depression symptoms between a group of children exposed to earthquake with a group of children not exposed to it, but with both groups potentially exposed to the same levels of post-earthquake adversities. The study included 2037 children, aged 9-17 years, who were assessed with self-completed questionnaires. The directly exposed group (N=1752) had significantly higher anxiety and PTSD scores than the indirectly exposed group (N=284), but no significant group differences were found in depression scores. Girls in both groups reported significantly more PTSD, anxiety and depressive symptoms than boys. Younger children reported significantly more PTSD and anxiety symptoms than the older ones. No significant interactions were found between direct exposure to earthquake, age group and gender. The severity of PTSD symptoms was most strongly predicted by greater perceived threat during the earthquake, whereas depression was most strongly predicted by the level of post-earthquake adversity. The severity of anxiety symptoms was most strongly predicted by female gender. These findings are discussed in relation to the need for screening and intervention following earthquake events.

The aim of this study was to analyse the prevalence of the most relevant clinical features of the diagnosis of systemic lupus erythematosus (SLE) in a sample of male patients with lupus as well as the incidence of the main causes of morbidity in a 5-year period after the diagnosis. A further aim of this study was to investigate the impact of gender on expression and morbidity of SLE. Data were collected from the medical records of 59 male and 535 female patients with SLE who were diagnosed at the hospitals in the region of Thessaloniki. Several differences in the expression and morbidity of the disease were found in relation to the gender of the patient. Male patients had a higher prevalence of thromboses, nephropathy, strokes, gastrointestinal tract symptoms and antiphospholipid syndrome when compared with female patients, but tended to present less often with arthralgia, hair loss, Raynaud's phenomenon and photosensitivity as the initial clinical manifestations. During the 5-year follow-up, positive associations have been found between male gender and the incidence of tendonitis, myositis, nephropathy and infections, particularly of the respiratory tract. In conclusion, this study has provided information regarding the features of clinical expression and morbidity in male patients, and has shown that gender is a possible factor that can influence the clinical expression of SLE.

Our study shows altered retinal microvascular morphology in RA patients. Inflammation appears as the biological link for the observed association between retinal microvascular abnormalities and subclinical atherosclerosis. Retinal arteriolar narrowing might play its own role in cardiovascular risk prediction in RA.
