| Abstract | BACKGROUND: Primary ciliary dyskinesia (PCD) is a genetic disease characterized by abnormally beating cilia. In these patients, levels of nasal nitric oxide (nNO) are lower than those observed in healthy subjects. OBJECTIVES: We identify the nNO levels in healthy pre-school uncooperative children and in PCD patients, in order the application of nNO measurement in the early identification of young children with PCD. METHODS: We measured nNO in 77 healthy children (50 uncooperative and 27 cooperative) and in 10 PCD patients. Fifteen cooperative healthy children were also asked to perform an uncooperative test. RESULTS: PCD patients presented low nNO levels (29.7+/-5.7 ppb) compared to those observed in healthy children (358.8+/-35.2 ppb; p<0.05). nNO levels were increased in healthy cooperative children (650+/-60.6 ppb; p<0.05) as compared to those uncooperative aging more than 6 month (309.1+/-45.9 ppb; p<0.05) or less (128.1+/-16.2 ppb; p<0.05). Twenty-four uncooperative children with nNO values < or = 200 ppb performed a second evaluation at least 6 months later and mean levels increased from 104.7+/-10.5 ppb to 169.9+/-19.6 ppb (p<0.05). In the 15 collaborative children nNO levels were higher during the breath holding manoeuvre (687.7+/-96.9 ppb) than during the tidal breathing manoeuvre (335.9+/-57.9 ppb; p<0.05). CONCLUSIONS: Healthy children have higher nNO levels than PCD patients. In 15% of uncooperative healthy children can be found low nNO levels, similar to PCD patients, but those values increased some months later, in successive evaluations. Nasal NO may be used for PCD screening even though repeated evaluations may be necessary in young children. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
