Compartment syndrome. Exclusively the result of increased pressure in the muscular compartment?

Summary The compartment syndrome (cs) is characterized by an increased tissue pressure in a limited space. Pathophysiologically, it is a multifactorial disease that is potentially induced by an initial trauma and develops according to the existence of cofactors. Cofactors are, for instance, the circulation of the patient and the initial treatment of the impending cs. In particular, the microcirculation is altered with endothelial destruction, development of a capillary leak, protein loss from intravasal space and the development of an interstitial and intracellular third space. An impaired drainage of the lymphatic and venous system causes a venous infarction. An arterial infarction results if the tissue pressure exceeds the arteriolar pressure. An accompanying ischemia reperfusion mechanism increases the trauma load. In disadvantageous cases, the patients are in danger of developing a multi-organ deficiency syndrome (MODS) by an uncontrolled inflammatory reaction, by intravasal volume loss and by a myonephropathic systemic reaction. Clinically, the patients suffer a disproportionate amount of pain, followed by neurological signs. Especially in noncompliant patients, tissue pressure measurement is useful. Resuscitation of the circulation as well as splitting of casts is important. In case of a manifest cs, dermatofasciotomy has to be performed as an emergency operation. Even if cs is diagnosed early and fasciotomy is carried out early, the development of sequellae cannot be avoided in every single case.      

Without Parental Consent: Conducting Research With Homeless Adolescents

ISSUES AND PURPOSE. To identify the ethical and legal implications of conducting research with homeless adolescents and to discuss guidelines for conducting research without parental consent.
CONCLUSIONS. Ethical principles of capacity, risk, postponement, and truthful disclosure within the context of the rights of minors to consent to healthcare treatment form the basis of the argument for allowing adolescents to consent to participate in research without parental consent when there is minimal risk or when such consent could place them at increased risk for harm.
PRACTICE IMPLICATIONS. Adolescents who are the target population for clinical research or who are intended recipients of nursing care should be involved in setting priorities, purposes, and protocols. Parents and other adults from their communities should be included in developing strategies to protect their confidentiality and privacy while helping them achieve autonomy in making informed health-related decisions.     

Effects of Nephritis No.3 Recipe on Nitric Oxide,Nitric Oxide Synthase Secreted by Cultured Mesangial Cells in Rats and the Gene Expression of Inducible Nitric Oxide Synthase

Objective:To explore the effect of the Nephritis No.3(N-3)recipe on nitric oxide(NO),nitric oxide synthase(NOS)secreted by cultured mesangial cells(MC)and its gene expression of the in-ducible nitric oxide synthase(iNOS).Methods:The drug(nephritis No.3)-containing serum was preparedwith serum pharmacological technique,and then was applied to react on mesangial cells cultured In fetalcalf serum(FCS)and cells cultured in FCS plus lipopolysaccharide.To observe the secretion of NO andNOS and the gene expression of iNOS by means of RT-PCR.Results:Under the two kinds of culture con-ditions,the content of NO and NOS in the groups with drug-containing serum were higher than thosewithout drug-containing serum(P<0.05,P<0.01),and the expression of iNOS mRNA was up-regula-ted too.Conclusion:The N-3 could significantly promote the secretion of NO and NOS and the mRNA ex-pression of iNOS in rats.

Surveillance of resistance in bacteria causing community-acquired respiratory tract infections

Bacterial resistance to antibiotics in community-acquired respiratory tract infections is a serious problem and is increasing in prevalence world-wide at an alarming rate. Streptococcus pneumoniae , one of the main organisms implicated in respiratory tract infections, has developed multiple resistance mechanisms to combat the effects of most commonly used classes of antibiotics, particularly the β -lactams (penicillin, aminopenicillins and cephalosporins) and macrolides. Furthermore, multidrug-resistant strains of S. pneumoniae have spread to all regions of the world, often via resistant genetic clones. A similar spread of resistance has been reported for other major respiratory tract pathogens, including Haemophilus influenzae , Moraxella catarrhalis and Streptococcus pyogenes . To develop and support resistance control strategies it is imperative to obtain accurate data on the prevalence, geographic distribution and antibiotic susceptibility of respiratory tract pathogens and how this relates to antibiotic prescribing patterns. In recent years, significant progress has been made in developing longitudinal national and international surveillance programs to monitor antibiotic resistance, such that the prevalence of resistance and underlying trends over time are now well documented for most parts of Europe, and many parts of Asia and the Americas. However, resistance surveillance data from parts of the developing world (regions of Central America, Africa, Asia and Central/Eastern Europe) remain poor. The quantity and quality of surveillance data is very heterogeneous; thus there is a clear need to standardize or validate the data collection, analysis and interpretative criteria used across studies. If disseminated effectively these data can be used to guide empiric antibiotic therapy, and to support—and monitor the impact of—interventions on antibiotic resistance.
