About DNA databasing and investigative genetic analysis of externally visible characteristics: A public survey.

During the last decade, DNA profiling and the use of DNA databases have become two of the most employed instruments of police investigations. This very rapid establishment of forensic genetics is yet far from being complete. In the last few years novel types of analyses have been presented to describe phenotypically a possible perpetrator. We conducted the present study among German speaking Swiss residents for two main reasons: firstly, we aimed at getting an impression of the public awareness and acceptance of the Swiss DNA database and the perception of a hypothetical DNA database containing all Swiss residents. Secondly, we wanted to get a broader picture of how people that are not working in the field of forensic genetics think about legal permission to establish phenotypic descriptions of alleged criminals by genetic means. Even though a significant number of study participants did not even know about the existence of the Swiss DNA database, its acceptance appears to be very high. Generally our results suggest that the current forensic use of DNA profiling is considered highly trustworthy. However, the acceptance of a hypothetical universal database would be only as low as about 30% among the 284 respondents to our study, mostly because people are concerned about the security of their genetic data, their privacy or a possible risk of abuse of such a database. Concerning the genetic analysis of externally visible characteristics and biogeographical ancestry, we discover a high degree of acceptance. The acceptance decreases slightly when precise characteristics are presented to the participants in detail. About half of the respondents would be in favor of the moderate use of physical traits analyses only for serious crimes threatening life, health or sexual integrity. The possible risk of discrimination and reinforcement of racism, as discussed by scholars from anthropology, bioethics, law, philosophy and sociology, is mentioned less frequently by the study participants than we would have expected. A national DNA database and the widespread use of DNA analyses for police and justice have an impact on the entire society. Therefore the concerns of lay persons from the respective population should be heard and considered. The aims of this study were to draw a broader picture of the public opinion on DNA databasing and to contribute to the debate about the possible future use of genetics to reveal phenotypic characteristics. Our data might provide an additional perspective for experts involved in regulatory or legislative processes.

Serious medical complications in children with cancer and fever in chemotherapy-induced neutropenia: Results of the prospective multicenter SPOG 2003 FN study

Fever and chemotherapy-induced neutropenia (FN) is the most frequent potentially lethal complication of therapy in children with cancer. This study aimed to describe serious medical complications (SMC) in children with FN regarding incidence, clinical spectrum, and associated characteristics.

Regular treatment with salmeterol and inhaled steroids for chronic asthma: serious adverse events

Epidemiological evidence has suggested a link between beta2-agonists and increased asthma mortality. There has been much debate about possible causal links for this association, and whether regular (daily) long-acting beta2-agonists are safe. This is an updated systematic review.

Pharmacological prevention of serious anaphylactic reactions due to iodinated contrast media: systematic review

OBJECTIVE: To review the efficacy of pharmacological prevention of serious reactions to iodinated contrast media. DESIGN: Systematic review. DATA SOURCES: Systematic search (multiple databases, bibliographies, all languages, to October 2005) for randomised comparisons of pretreatment with placebo or no treatment (control) in patients receiving iodinated contrast media. Review methods Trial quality was assessed by all investigators. Information on trial design, population, interventions, and outcomes was abstracted by one investigator and cross checked by the others. Data were combined by using Peto odds ratios with 95% confidence intervals. RESULTS: Nine trials (1975-96, 10 011 adults) tested H1 antihistamines, corticosteroids, and an H1-H2 combination. No trial included exclusively patients with a history of allergic reactions. Many outcomes were not allergy related, and only a few were potentially life threatening. No reports on death, cardiopulmonary resuscitation, irreversible neurological deficit, or prolonged hospital stays were found. In two trials, 3/778 (0.4%) patients who received oral methylprednisolone 2x32 mg or intravenous prednisolone 250 mg had laryngeal oedema compared with 11/769 (1.4%) controls (odds ratio 0.31, 95% confidence interval 0.11 to 0.88). In two trials, 7/3093 (0.2%) patients who received oral methylprednisolone 2x32 mg had a composite outcome (including shock, bronchospasm, and laryngospasm) compared with 20/2178 (0.9%) controls (odds ratio 0.28, 0.13 to 0.60). In one trial, 1/196 (0.5%) patients who received intravenous clemastine 0.03 mg/kg and cimetidine 2-5 mg/kg had angio-oedema compared with 8/194 (4.1%) controls (odds ratio 0.20, 0.05 to 0.76). CONCLUSIONS: Life threatening anaphylactic reactions due to iodinated contrast media are rare. In unselected patients, the usefulness of premedication is doubtful, as a large number of patients need to receive premedication to prevent one potentially serious reaction. Data supporting the use of premedication in patients with a history of allergic reactions are lacking. Physicians who are dealing with these patients should not rely on the efficacy of premedication.

[Juvenile chronic arthritis: a rare disease with potentially serious consequences]

The term juvenile chronic arthritis covers several nosological entities with very different clinical presentation, course and prognosis. This review addresses non-rheumatologists and non-pediatricians. Diagnostic criteria, clinical presentation of the most common nosological subgroups and relevant investigations are spotlighted. Therapeutic guidelines are presented, bearing in mind, that for each child an individual interdisciplinary plan has to be elaborated. This would involve close cooperation between the pediatrician, the pediatric rheumatologist, the family doctor, parents and, if necessary, the physiotherapist, ergotherapist, social worker, ophthalmologist, orthopedic surgeon and school teachers. It is essential that each member of this therapeutic team reports regularly.
