Objective To determine the clinical features of childhood vitiligo in Han nationality.Methods A standardized questionnaire was used to clinically investigate 396 cases of vitiligo in patients aged less than 12 years;825 adult patients with vitiligo served as controls.Data analysis was done by SPSS 10.0.Results In child patients with vitiligo,46.2% were males,and 53.8%females;there was no statistically significant difference in gender ratio between the childhood and adult groups(P<0.05).The incidence of segmental vitiligo was 33.3%in children,significantly higher than that in adult patients(13.5%).On the contrary,the incidence of generalized vitiligo was significantly lower in children han in adult patients(4.3%vs 11.6%).A family history of vitiligo was observed in 12.4%of children,and in 12.7% of adults,withoutsignificant difference between the two groups.For both childhood and adult vitiligo patients,the incidence of vitiligo was significantly higher in firSt-degree relatives than in second-degree relatives.The most common precipitating factor of childhood vitiligo was trauma.The incidence of halo nevi was higher in patients with childhood vitiligo compared to patients with adult vitiligo,while thyroid disease was seen more frequently in adult patients.Conclusion There are some differences in clinical characteristics of vitiligo between children and adults.

PURPOSE: In recent years, a variety of acute respiratory distress syndrome (ARDS) evaluation systems have been developed worldwide; however, they are not so convenient for the doctors clinically, we decided to establish and evaluate a simplified evaluation system of ARDS (SESARDS). MATERIALS AND METHODS: Data from 140 ARDS patients (derivation data set) were collected to screen for prognostic factors affecting outcomes in ARDS patients. By logistic regression analysis, scores were allocated to corresponding intervals of the variables, respectively, by means of analysis of the frequency distribution to establish a preliminary scoring system. Based on this primary scoring system, a definitive evaluation scheme was created through consultation with a panel of experts. The scores for the validation data set (92 cases) were assigned and calculated by their predictive mortality with the SESARDS and acute physiology and chronic health evaluation II (APACHE II). The performance of SESARDS was compared with that of APACHE II by means of statistical analysis. RESULTS: The factors of age, pH, Glasgow coma scale (GCS), oxygenation index (OI), and the lobes of lung were associated with prognosis of ARDS respectively. The sensitivity and specificity of SESARDS for the validation data set were 96.43% and 58.33%, respectively. On the AUC, no significant difference between APACHE II and SESARDS was detected. There were no significant differences between the prediction and the actuality obtained by SESARDS for the validation data set the SESARDS scores were positively correlated with the actual mortality. CONCLUSION: SESARDS was shown to be simple, accurate and effective in predicting ARDS progression.
