Assessment on self-care, mobility and social function of children with spina bifida in Turkey

Neural Regeneration Research 2014年第12期9卷 1234-1240页

作者： Hulya Sirzai Beril Dogu Selamet Demir figen yilmaz Banu Kuran Ankara Physical Medicine and Rehabilitation Education and Research Hospital Department of Physical Medicine and Rehabilitation Sisli Etfal Education and Research Hospital

The aim of the study was to investigate the functional performance in children with spina bifida, using the Pediatric Evaluation of Disability Inventory （PEDI） to look into capacity of twen- ty-eight children with spina bifida with lesions at different levels in different dimensions of self- care, mobility and social function. Mean age of the patients was 3.5 ± 2.3 （1-10） years. In the muscle test carried out, 13 patients （44.8%） had no movements including pelvic elevation in lower extremity muscles and they were at level 5. Sixteen patients （54%） were non-ambulatory according to the Hoofer ambulation classification. Raw and scale scores in the self-care, mobil- ity and social function domains both in the functional skill scale and in the caregiver scale were found to be lower compared to the data of the normal population. A statistically significant correlation was observed in the self-care values of the Functional Skills Scales and the Caregiver Assistance Scale measurements, which was positive for age and negative for Functional Ambu- lation Scale and muscle test （P 〈 0.05）. A positive relation was found between the Functional Skills Scales-mobility area and age while a negative relation was observed between Functional Ambulation Scale and muscle test （P 〈 0.005）. A negative relation was also found between Care- giver Assistance Scale-mobility and Functional Ambulation Scale and muscle test （P 〈 0.005）. In our study, the functional performance of the children was found to be low. Low-level lesions, encouraging muscular strength and independence in mobility are all very important factors for functional independence.

World Journal of Hepatology 2016年第33期8卷 1466-1470页

作者： Oya Balci Sezer Deniz Celik Nihal Tutar figen Ozcay Department of Pediatric Gastroenterology Hepatology and NutritionBaskent University Department of Child Health and Diseases Baskent University Department of Radiology Baskent University

AIM To determine the laboratory and radiologic parameters, including the platelet count(PC)-to-spleen diameter(SD) ratio as a non-invasive marker that may predict the presence of esophageal varices(EV) in children with *** Eighty-nine patients with cirrhosis, but without a history of variceal bleeding were prospectively included. The children were grouped into 6-12 and 12-18 years of age groups. These groups were also divided into 2 subgroups(presence and absence of EV). All of the patients underwent a complete biochemical and radiologic evaluation. The PC(n/mm^3)-to-SD(mm) ratio was calculated for each patient. RESULTS Sixty-nine of 98(70.4%) patients had EV. The presence of ascites in all age groups was significantly associatedwith the presence of EV. There were no differences in serum albumin levels, PC, SD and the PC-to-SD ratio between the presence and absence of EV groups in both age groups(P > 0.05). CONCLUSION Laboratory and radiologic parameters, including the PC-to-SD ratio as a non-invasive marker(except for the presence of ascites), was inappropriate for detecting EV in children with cirrhosis.
