In the field of paediatric health care, measures based on consequences of health conditions have been recently developed to screen for children with special health care needs. These tools have been primarily used in survey research. The aim of this cross-sectional clinical study is to test the performance of a screener for identifying children with special health care needs (CSHCN) in a population of children with chronic conditions diagnosed and treated in different European paediatric hospitals. In the current study, the screener was employed in a sample of children with different chronic conditions (asthma, arthritis, dermatitis, epilepsy, cystic fibrosis, diabetes and cerebral palsy) across seven European countries; 456 parents of children, aged 4-7, 8-12, and 13-16 years, responded to the screener items. The study included a range of clinical measures to assess the severity of the conditions as well measures on functional health status. The prevalence of children identified positively with the CSHCN screener was 80%, which was higher than in survey estimates in the United States. Considerable variation in the screener classification was found between chronic conditions with cystic fibrosis and epilepsy showing higher rates, and skin conditions lower rates. There was no significant relationship between the screener classification and functional limitation. Findings of this study support in general the validity of the children with special health care needs screener, which shows, however, a differential validity across specific conditions. Several clinical and theoretical explanations for the lack of identifying some children with chronic conditions and the considerable variation between the conditions are discussed.

Hypochlorous acid (HOCl) is a powerful oxidant generated from H(2)O(2) and chloride ions by the heme enzyme myeloperoxidase (MPO) released from activated leukocytes. In addition to its potent antibacterial effects, excessive HOCl production can lead to host tissue damage, with this implicated in human diseases such as atherosclerosis, cystic fibrosis, and arthritis. HOCl reacts rapidly with biological materials, with proteins being major targets. Chlorinated amines (chloramines) formed from Lys and His side chains and alpha-amino groups on proteins are major products of these reactions; these materials are however also oxidants and can undergo further reactions. In this study, the kinetics of reaction of His side-chain chloramines with other protein components have been investigated by UV/visible spectroscopy and stopped flow methods at pH 7.4 and 22 degrees C, using the chloramines of the model compound 4-imidazoleacetic acid and N-alpha-acetyl-histidine. The second-order rate constants decrease in a similar order (Cys > Met > disulfide bonds > Trp approximately alpha-amino > Lys >> Tyr > backbone amides > Arg) to the corresponding reactions of HOCl, but are typically 5-25 times slower. These rate constants are consistent with His side-chain chloramines being important secondary oxidants in HOCl-mediated damage. These studies suggest that formation and subsequent reactions of His side-chain chloramines may be responsible for the targeted secondary modification of selected protein residues by HOCl that has previously been observed experimentally and highlight the importance of chloramine structure on their subsequent reactivity.

G-protein-coupled receptor kinases (GRKs) interact with the agonist-activated form of G-protein-coupled receptors (GPCRs) to effect receptor phosphorylation and to initiate profound impairment of receptor signalling, or desensitization. GPCRs form the largest family of cell surface receptors known and defects in GRK function have the potential consequence to affect GPCR-stimulated biological responses in many pathological situations. This review focuses on the physiological role of GRKs revealed by genetically modified animals but also develops the involvement of GRKs in human diseases as, Oguchi disease, heart failure, hypertension or rhumatoid arthritis. Furthermore, the regulation of GRK levels in opiate addiction, cancers, psychiatric diseases, cystic fibrosis and cardiac diseases is discussed. Both transgenic mice and human pathologies have demonstrated the importance of GRKs in the signalling pathways of rhodopsin, beta-adrenergic and dopamine-1 receptors. The modulation of GRK activity in animal models of cardiac diseases can be effective to restore cardiac function in heart failure and opens a novel therapeutic strategy in diseases with GPCR dysregulation.

Health-related quality of life (HRQOL) assessment in children and adolescents with chronic health conditions is increasingly considered as a relevant topic. The aim of the EU-funded DISABKIDS project is to develop, test, and implement European instruments for the assessment of HRQOL of children and adolescents with disabilities and their families. The current paper describes the development and pilot testing of a chronic generic HRQOL measure. Using literature searches, expert consulting and focus groups with children/adolescents and their families, items of the instruments were developed and translated into the respective languages. A pilot test with 360 children and adolescents was conducted. Children and adolescents (8-12, 13-16 years) with different chronic health conditions (asthma, epilepsy, diabetes, arthritis, atopic dermatitis, cerebral palsy, and cystic fibrosis) as well as their families were included. Data were analysed according to predefined psychometric and content criteria. Psychometric analyses resulted in a 56-item chronic generic HRQOL questionnaire with six domains ('Medication', 'Physical', 'Emotion', 'Independence', 'Social Inclusion', 'Social Exclusion') with acceptable internal consistency.

Morphological, cultural, and immuno-histochemical characteristics of "Nanobacterium sanguineum" (NB) described in the literature are reviewed. NB is reported to be a motile, Gram negative organism that divides by binary fission within a calcium-coated slimy shell; this yeast-like shell replicates by budding. It measures between 20 and 200 nm with a unique structure containing 16S ribosomal RNA. NB has been observed by electron microscopy in coronary artery plaques (CAD) and in kidney stones (KS) found in renal diseases. On the basis of supportive literature, we suggest that NB is not only present in the human body but also has auxiliary association with human ailments without a specific etiological role; anti-NB antibody has been detected in subjects with calcified lesions and inflammation in diverse ailments including choriodecidual inflammation in pregnancy, ovarian cancers, arthritis and even Alzheimer's disease. More recent report on the detection and vertical transmission of NB antigen and anti-NB antibody in HIV-infected mothers supports the view that NB might be an important opportunistic infective agent contributing to HIV pathology; we note that the presence of viable and transmitting NB was not studied and suggest further studies to establish vertical transmission of NB in HIV-infected persons. On the basis of the foregoing we suggest that NB possibly exacerbates human ailments and raise the question: Is NB a new life-form in search of human ailment or a commensal organism? Recognizing the presence of NB in the human body, we discuss clinical trials, reported in the literature relevant to its eradication, with a rectal suppository containing very high amounts of disodium EDTA and tetracycline. We suggest that tetracycline in this formulation acted in combination with EDTA, more as a chelating agent than an antibiotic; oxytetracycline- a non-chelating form of tetracycline-does not inhibit or kill NB. Evaluation of anti-NB effect of orally administrable and potentially safer as well as therapeutically more acceptable chelating agent -ascorbic acid, acting alone or in combination with antibiotics-that eradicates another slime forming bacterium - Pseudomonas aeruginosa - in children with cystic fibrosis, is suggested.

Even though the field of medicine has developed tremendously, the wide variety of cancer is still among chronic and life threatening disease today. Therefore, the specialists constantly research and try every possible way to find cure or preventive ways to stop its further development. For this reason, studies concerning the chronic disease such as cancer have been spread to many different fields. In this regard, many other alternative ways besides medicine, are used in prevention of cancer. Nutritional therapy, herbal therapy, sportive activities, art therapy, music therapy, dance therapy, imagery, yoga and acupuncture can be given as examples. Among these, dance/movement therapy which deals with individuals physical, emotional, cognitive as well as social integration is widely used as a popular form of physical activity. The physical benefits of dance therapy as exercise are well documented. Studies have shown that physical activity is known to increase special neurotransmitter substances in the brain (endorphins), which create a state of well-being. And total body movement such as dance enhances the functions of other body systems, such as circulatory, respiratory, skeletal, and muscular systems. Regarding its unique connection to the field of medicine, many researches have been undertaken on the effects of dance/movement therapy in special settings with physical problems such as amputations, traumatic brain injury, and stroke, chronic illnesses such as anorexia, bulimia, cancer, Alzheimer's disease, cystic fibrosis, heart disease, diabetes, asthma, AIDS, and arthritis. Today dance/movement therapy is a well recognized form of complementary therapy used in hospitals as well as at the comprehensive clinical cancer centres.

We report on a 28-year-old man with known cystic fibrosis who presented with pain and cutaneous nodules in the elbow joints. His symptoms had appeared episodically in the previous months, they were always self-limiting, and independent of pulmonary exacerbations. A radiograph of the joints was unremarkable. These findings fit well with a special form of CF-related arthritis. As in the case of classical CF arthritis, the treatment to be considered is, in particular, symptomatic administration of non-steroidal anti-inflammatory drugs and possibly glucocorticoids. Also under discussion as a further possibility is the use of antibiotics. Our patient has always refused medication. The condition again proved to be self-limiting. In contrast to the classical form of CF arthritis, the special form is not associated with either joint swelling or local warmth. In the presence of arthritic symptoms in CF patients, consideration must always be given to a hypertrophic pulmonary osteoarthropathy. The latter, however, shows typical radiological changes and is exacerbated by lung infections. The presence of arthritic pathologies in a patient with CF further underscores the fact that CF is a multiorgan morbid condition.

Increased serum levels of the S100A8 (MRP-8) protein have been reported in inflammatory conditions including bacterial infection, arthritis, and cystic fibrosis (CF). This protein is expressed constitutively with S100A9 (MRP-14) in neutrophils and is regulated by inflammatory stimulants. It has been hypothesized that increased inflammatory response to persistent bacterial infection is a major feature of CF lung disease. Therefore, the authors wished to determine the involvement of these two proteins in the innate defense response of the bronchial epithelium to lipopolysaccharide (LPS). Human bronchial epithelial cells (16HBE14o-) and primary bronchial epithelial cells (NHBE) were grown at air-liquid interface (ALI) and stimulated for up to 96 hours with LPS from Pseudomonas aeruginosa. The 16HBE14o- cells responded to LPS with a 2.9-fold increase in S100A8 mRNA production after 12 hours. S100A9 mRNA production was increased by 1.8-fold after 12 hours and 2.9-fold after 24 hours. It was also found that the S100A8 and S100A9 proteins were increased in the secretions of the 16HBE14o- and NHBE cells after LPS stimulation. This finding suggests that S100A8 and S100A9 are involved in the innate defense of the bronchial epithelium.
