[Quality parameters in the treatment of acute stroke: comparison of various regional treatment concepts]. / Qualitätsparameter der akuten Schlaganfallversorgung: Gegenüberstellung unterschiedlicher regionaler Versorgungskonzepte.

BACKGROUND: The long-term prognosis of stroke patients is still dependent in particular on the timing of a correct diagnosis, immediate initiation of a suitable specific therapy and competent treatment in a stroke unit. Therefore, nationwide attempts are being made to establish a comprehensive coverage of the necessary specific competence and infrastructural requirements. Divergent regional circumstances and economic viewpoints determine the characteristics of the various healthcare concepts and the interplay between participating cooperation partners. This article compares the development with respect to three qualitative treatment parameters exemplified by four regional healthcare models during the time period 2008-2011. METHODS: The hospitalization rates for patients with transitory ischemic attacks, ischemic and hemorrhagic stroke, the case numbers for stoke unit treatment and the rates of systemic thrombolysis and mechanical thrombectomy in the regions of Berlin, the Ruhr Area, Ostwestfalen-Lippe and southeast Bayern (TEMPiS) are presented based on the data from the DRG statistical reports for the years 2008 and 2011. RESULTS: The average hospitalization rates for ischemic stroke patients (brain infarct ICD 163) in the time period from 2008 to 2011 were 294 per 100,000 inhabitants for the Ruhr Area, 257 per 100,000 inhabitants for Ostwestfalen-Lippe and 265 per 100,000 inhabitants each for Berlin and southeast Bayern. The complex stroke treatment quota for southeast Bayern in 2008 was 31 % and 47 % in 2011 and the respective quotas for the other regions studied were 42-44 % and 58-59 %. The rate of systemic thrombolysis in 2008 ranged between 4.2 % and 7.4 % and in 2011 the increase in the range for the 4 regions studied was between 41 % and 145 %. In 2011 the thrombectomy quota of 2 % in the Ruhr Area was the only one which was above the national average of 1.3 % of all brain infarcts. DISCUSSION: Stroke is a common disease in the four regions studied. For the established forms of therapy, complex treatment of stroke and systemic thrombolysis, the positive effect of structurally improved approaches in the four different regional treatment concepts could be confirmed during the course of the observational time period selected. Mechanical thrombectomy which is currently still considered to be an individual healing attempt, was used significantly more often in the Ruhr Area in 2011 than in the other three regions studied. A standardized referral procedure had previously been established in the metropolitan regions.

Effect of gilt seropositivity to Lawsonia intracellularis (LI) on their offspring's seropositivity to LI and on diarrhoea after a pure-culture challenge.

This study was done in a large Croatian pig-production unit. Blood samples from late-pregnancy gilts were tested by an indirect immunofluorescence-antibody (IFA) serum assay for Lawsonia intracellularis (LI). Ten IFA-positive and 10 IFA-negative gilts were selected. The 2-week-old piglets (97 from positive gilts, and 98 from negative gilts) were inoculated intragastrically with pure culture of LI. All pigs were tested until slaughter for seroprevalence of LI. Blood samples were collected at 5, 8, 11, 14, 17, 20, 23 and 26 weeks of age. Seropositivity in offspring of IFA-negative gilts was highest at age 5 weeks (84%) and declined gradually from week 11 to only 10% at week 26. At the same time, the offspring of IFA-positive gilts showed lower and faster-decaying seroprevalence: only 32% at week 5 and 0% starting at week 17. There was no difference in the pen-days of diarrhoea between the offspring of LI-seropositive and -seronegative gilts.

Facilitation of skilled finger movements by repetitive peripheral magnetic stimulation (RPMS) - a new approach in central paresis.

A new therapeutic method for the rehabilitation of central paresis of the upper extremity, especially of fine skilled finger movements, is presented. The therapeutic concept is the activation of reorganization processes in the CNS. These processes are elicited by the induction of proprioceptive input to the CNS which corresponds physiologically to the lost input during active movements. The input is generated by repetitive peripheral magnetic stimulation (RPMS) at the innervation zone of the paretic muscles. The stimulation leads to a motion of the activated muscles. The proprioceptive input is generated by two mechanisms: adequately by activation of mechanoreceptors of the stimulated muscles during the induced contractions and relaxations and inadequately by direct activation of the involved sensorimotor afferents. The method has been applied to 52 patients suffering from spastic paresis of the upper extremity. A simple clinical quantification using the Ashworth scale revealed that spasticity could be remarkably (1-2 points) reduced already by one session of RPMS lasting 15 minutes. In order to get an objective insight into the improvement of active motor performances, a neurophysiological investigation of active finger extensions was performed in eight patients suffering from a central hemiparesis. Following RPMS of the paretic finger extensors, the patients could perform rapid finger extensions with larger displacement and velocity at diminished amounts of EMG activity.

Ruptured appendix after elective abortion. A case report.

Abdominal pain and fever after an uncomplicated elective abortion usually point to incomplete abortion and endometritis. We treated a woman for acute suppurative appendicitis one week after such an abortion. When fever, nausea, vomiting and pain are not relieved by the standard doses of medication, acute appendicitis must be added to the usual gynecologic differential diagnoses.

Insertion of the laparoscopic Trocar without the use of carbon dioxide gas.

Nine-hundred-and-fourteen patients have undergone the single puncture Falope Ring laparoscopic tubal ligations in a community hospital without prior insufflation of carbon dioxide gas. Anesthesia time averaged 10.5 minutes, surgical procedure time averaged 8.1 minutes. The patients left the hospital in satisfactory condition in the afternoon of the procedure. The only complication was a failed ligation (0.1%). Two-week follow-up showed no untoward complications. Omission of carbon dioxide insufflation before Trocar insertion lowers complications such as nausea, emesis, and post-operative pain. Also, anesthesia and surgical times are reduced. None of the patients required intubation during anesthesia.
