Zur offenen Markdrahtung von Unterarmfrakturen

Zusammenfassung Es wird über 15 Fälle von Brüchen beider Unterarmknochen berichtet, die auf Grund besonderer Gegebenheiten (wiederholte erfolglose Repositions- und Retentionsversuche, schwere Nebenverletzungen usw.) einer operativen Behandlung (intramedulläre Fixation mittels Kirschnerdrähten) unterzogen wurden. Die angewandte operative Technik und die Nachbehandlung werden im Detail beschrieben. Das funktionelle Endergebnis war bei 11 Patienten gut (Wiederherstellung der vollen Berufsfähigkeit), bei 2 Patienten entsprechend (Einschränkung der Funktionstüchtigkeit) und bei 2 weiteren schlecht (Pseudarthrosen).Mit 6 Textabbildungen (27 Einzelbilder)Auszugsweise vorgetragen bei der Tagung der Europäischen Föderation des International College of Surgeons in Hamburg am 2.

Readiness to quit cigarette smoking, intimate partner violence, and substance abuse among arrested violent women

Cigarette smoking is a leading cause of preventable mortality in the United States. Not much data are available regarding the prevalence and correlates of cigarette smoking in female perpetrators of intimate partner violence (IPV). Ninety-eight arrested violent women were recruited from court-referred batterer intervention programs. The prevalence of smoking in the sample was 62%. Smokers reported higher levels of substance abuse, psychopathology, general violence, and IPV perpetration and victimization than nonsmokers. Most smokers (65%) indicated a desire to quit within the next year. The results highlight the importance of screening for cigarette smoking in violence intervention programs and offering assistance to those who choose to quit.     

Separation of indocyanine green boluses in the human brain and scalp based on time-resolved in-vivo fluorescence measurements

Non-invasive detection of fluorescence from the optical tracer indocyanine green is feasible in the adult human brain when employing a time-domain technique with picosecond resolution. A fluorescence-based assessment may offer higher signal-to-noise ratio when compared to bolus tracking relying on changes in time-resolved diffuse reflectance. The essential challenge is to discriminate the fluorescence originating from the brain from contamination by extracerebral fluorescence and hence to reconstruct the bolus kinetics; however, a method to reliably perform the necessary separation is missing. We present a novel approach for the decomposition of the fluorescence contributions from the two tissue compartments. The corresponding sensitivity functions pertaining to the brain and to the extracerebral compartment are directly derived from the in-vivo measurement. This is achieved by assuming that during the initial and the late phase of bolus transit the fluorescence signal originates largely from one of the compartments. Solving the system of linear equations allows one to approximate time courses of a bolus for each compartment. We applied this method to repetitive measurements on two healthy subjects with an overall 34 boluses. A reconstruction of the bolus kinetics was possible in 62% of all cases.
