Abstract

Environmental impact assessment (EIA) is a procedure, which helps to examine environmental impacts caused by proposed projects. The areas of higher erosion risk are considered as the areas with higher landscape value from the conservation demands point of view.

Abstract

Systemic sclerosis (SSc) represents extremely rare disease with majority of data coming from adults. Studies comparing juvenile- (jSSc) and adult-onset (aSSc) patients are limited. We aimed to compare clinical features, treatment modalities and survival rates of jSSc and aSSc patients. A retrospective study among pediatric and adult Scl patients has been performed. Demographic characteristics, clinical features, autoantibody profiles, and treatment data were retrieved from the databases. Survival analysis was done using Kaplan-Meier plot and factors associated with mortality were identified with multiple regression analysis. A total of 158 adults and 58 juvenile Scl patients were identified. The mean age at the disease onset was 37±14.7 vs. 8.8 ± 4.1 years, mean age at diagnosis 42±15.2 vs. 10.4 ± 3.8 years and mean follow-up duration was 6.3 ± 4.9 years vs. 6.6 ± 4.9 years for aSSc and jSSc patients, respectively. The frequency of interstitial lung disease (ILD) (50.9% vs 30%, p <0.001) and systemic hypertension (17.9% vs 0, p = 0.009) was significantly higher among aSSc. While aSSc patients had presented mostly with limited cutaneous subset (74.1%), diffuse cutaneous subset was the dominant subset among jSSc (76.7%), (p <0.001). The mortality rate was significantly higher among adults (p = 0.005). The ILD (p = 0.03) and cardiac insufficiency (p = 0.05) were independent risk factors of mortality in both aSSc and jSSc patients. Juvenile and adult-onset Scl represent rarely seen conditions with different clinical phenotypes. Pediatric patients with LS are more commonly seen by pediatric rheumatologists, in contrary to adults. Diffuse disease subset is the dominant form among juvenile patients, whereas limited form is the main disease subset among adults. On the other hand, juvenile-onset patients have a better survival than those with adult-onset. [Display omitted] [ABSTRACT FROM AUTHOR]

50. Balance in essential tremor during tandem gait: Is the first mis-step an important finding?

Abstract

Abstract: Essential tremor (ET) is the most commonly diagnosed movement disorder. ET may cause substantial loss of motor skills and balance with advanced age. We compared abnormalities in tandem gait with daily activity and Fahn–Tolosa–Marin Tremor Rating Scale (FTMTRS) scores in 90 ET patients. All patients performed a 15-step tandem three times. The mean of first mis-steps was accepted as the tandem index (TI). The mean age was 61.4±17years; the mean duration of tremor was 6.7±4years; and there were 36 men and 54 women. There was no significant difference for age or sex between patients and controls. Head (24.6%), jaw (5.5%), voice (11%), and tongue tremors (1.5%) were identified in ET patients. Rest (2.5%), postural (95%), and kinetic tremors (54%) were detected in the upper extremities. Postural tremor was found in the lower extremities of 5%. The mean TI was 8.3±4 (median, 8) in ET patients, and 10.6±3.9 (median, 10) in controls (p =0.04). Correlation analysis of TI and FTMTRS scores showed tandem gait was significantly correlated with age, total tremor score, postural and kinetic extremity tremor, writing, drawing, pouring, feeding, and working scores. Linear regression showed a significant effect of age and FTMTRS score on TI. The decrease in balance control is apparent with advancing age. Balance disorders were more pronounced in ET patients. Although first mis-step in tandem gait is not as detailed as dynamic balance tests, it can be a simple method for detecting balance disorders. [Copyright &y& Elsevier]
