Do children with primary nocturnal enuresis have a retarded bone age? A cross‐sectional study

OBJECTIVE: Nocturnal enuresis is a common pediatric problem, the etiology of which is unclear. In recent years, various studies have been published stating that children with nocturnal enuresis exhibit growth and skeletal maturation retardation. METHODS: In this cross-sectional study, we included 27 patients (16 boys, 11 girls) between the ages of 6 and 14 years who had presented with primary nocturnal enuresis (PNE) complaints. We included in the evaluation 19 healthy subjects (12 boys, 7 girls), who were the siblings of the children with PNE, as the control group. RESULTS: The patients in both groups were similar in chronological age, bone age, height and weight, with no significant difference between groups (P>0.05). CONCLUSION: The two groups in our study consisted of the same genetic background. Thus, our results were found to be different from the previous studies. We have concluded that there is no direct relationship between enuresis nocturnal and skeletal maturation.     

Nursing in the health care system of the postmodern world: crossroads, paradoxes and complexity

Entering the postmodern world in which society is confronting crossroads, paradoxes, and complexity, the health care system is encountering a transformation more comprehensive and revolutionary than has ever been seen before. Analysis of the state of nursing vis a vis these transformations indicates that the current paradigm does not ensure the existence of the profession in the postmodern health care system. That is because of increased difficulties in consolidating the economic and quality issues into the core of nursing, and in understanding the complexity inherent in health related situations.     

Reliability of dual diagnosis. Substance dependence and psychiatric disorders.

The Structured Clinical Interview for DSM-III-R was used to examine the effects of the co-occurrence of psychiatric and substance dependence disorders on diagnostic reliability. The test-retest reliability over a 1-week period was studied in groups of: a) individuals with current substance abuse diagnoses (N = 97), b) individuals with past, but not current, drug histories (N = 146), and c) individuals without substance abuse diagnoses (N = 356; primarily psychiatric patients). A measurement of reliability (Kappa coefficients) was estimated for four general psychiatric categories (psychotic, mood, anxiety, and eating disorders), along with specific most-frequent diagnoses in each category (schizophrenia, major depression, panic disorders, and bulimia nervosa, respectively). Past use and non-drug-use groups were similar in their generally reliable reporting of current and past psychiatric disorders. However, current mood and psychotic disorders were less reliably diagnosed in the group with current substance use disorders.     

Metabolic response of isolated liver cells to in vivo phagocytic challenge

This study elucidates the in vivo metabolic response of different liver cells after a single phagocytic challenge. In vivo glucose uptake of different tissues and isolated liver cells was determined by a sequential double labeling version of the 2-deoxyglucose technique. After latex administration, glucose uptake more than doubled in the liver, increased by about 50% in the spleen and lung and was not changed in muscle and testis. Within 10 min after intravenous injection of latex beads, neutropenia developed, with no change in the number of lymphocytes. This was accompanied by a marked influx of polymorphonuclear leukocytes into the liver. Latex was found in 52%, 35%, and 14% of the isolated Kupffer cells, polymorphonuclear leukocytes and endothelial cells, respectively. In vivo glucose uptake increased by 111%, 142%, and 43% in these cells. Glucose uptake by the latex-free hepatocytes was also elevated, presumably by way of intercellular signals between parenchymal and non-parenchymal liver cells. Indomethacin pretreatment resulted in the delay of neutrophil immigration into tissues without any change in the glucose response of different liver cells. Thus phagocytic stimulation in vivo results in marked neutropenia, migration of neutrophils into the liver, increased glucose uptake by phagocytic cells of the liver and enhanced glucose metabolism by the non-phagocytic parenchymal cells.
