Psoriasis in childhood and adolescence: evaluation of demographic and clinical features

BACKGROUND: The present study was aimed to define the gender ratio, familial occurrence, age of onset, precipitating factors, clinical types, nail and joint involvement of psoriasis in childhood and adolescence in Turkey. METHODS: A total of 61 children with psoriasis under 18 years old were evaluated retrospectively, for age, gender, age of disease onset, family history, concomitant disease, the clinical type of psoriasis, clinical localization, nail and joint involvement and treatment modalities. RESULTS: Of the patients, 23 (37.70%) were boys and 38 (62.30%) were girls. Mean age was 9.28 +/- 4.02 years in girls and 11.18 +/- 3.85 years in boys (9.96 +/- 4.03 years in all children). Mean age at the onset of the disease was 6.81 +/- 4.11 years in girls and 7.03 +/- 4.28 years in boys (6.89 +/- 4.14 years in all patients). In 14 (23%) cases, a positive family history was detected. The most frequent probable triggering factors were upper respiratory tract infections (14.8%) and positive throat culture for A group ss-hemolytic streptococcus (21.3%). Frequency of emotional stress and psychiatric morbidity were 54% and 9.8%, respectively. The most frequent localizations at onset were trunk (44.3%), extremities (54.0%), and scalp (36.0%). Three children (4.9%) had a history of dissemination from psoriatic diaper rash. In total, 51 (83.6%) patients presented with psoriasis vulgaris, eight (13.1%) with generalized pustular psoriasis, and the remaining two (3.3%) with erythrodermic psoriasis. CONCLUSION: The incidence of psoriasis among dermatological patients in childhood and adolescence was 3.8%. The disease tends to appear earlier in girls than boys. The authors suggested that stress and upper respiratory infections are the most important triggering factors in childhood and adolescence psoriasis.     

Does prophylactic sotalol and magnesium decrease the incidence of atrial fibrillation following coronary artery bypass surgery: a propensity-matched analysis

Background  

Atrial fibrillation can occur in up to 40% of patients undergoing coronary surgery.     

Macular recovery time, diabetic retinopathy, and clinical variables after 7 years of improved glycemic control.

Effects of long-term improved glucose control on neurosensory retinal function are investigated. Changes in macular recovery of nyctometry (photostress) are assessed in 45 insulin-dependent diabetic patients between study start and after 7 years prospective follow-up (the Oslo Study). Intensified insulin treatment improved glycosylated hemoglobin (HbA1) from 11.7 +/- 2.2% at start to a 7-year cumulative mean of 9.5 +/- 1.5% (p less than 0.0001). Improved macular recovery performance was observed in patients with 7-year mean HbA1 below 10%, compared to a worsening in those above 10% (p less than 0.001-0.02), and non-proliferative retinopathy progressed less in those with HbA1 below 10%, than in those above (p less than 0.01). Macular recovery at study start did not predict progression or outcome of retinopathy 7 years later. Intraocular pressure fell during the 7 years (p less than 0.001) and was cross-sectionally negatively correlated to macular recovery at the 7-year end-point (p less than 0.001-0.002). Macular recovery was not related to age, duration of diabetes, systemic blood pressure, or urinary albumin excretion level. The study indicates that severity of retinopathy, glycemic control and intraocular pressure are interesting covariants to neurosensory dysfunction in diabetes. Furthermore, the study suggests a critical level of long-term blood glucose or retinopathy, or both, above which neurosensory function of macular recovery is significantly reduced.
