    Notes: Summary The early treatment of acute myocardial infarction has changed rapidly in recent years. Given the fact that an occlusive coronary thrombus can be found in most infarct patients within 4 h after clinical symptoms, the idea of instituting medical or mechanical recanalization of the occluded vessel is intriguing. However, invasive measures are time consuming, expensive and not freely available to a great number of patients. Thus, only i.v. fibrinolytic therapy of acute myocardial infarction will gain wider application in the near future. Several concepts have been worked out, one of which uses a high-dosage streptokinase or urokinase regimen. A different therapeutic alternative has been made possible by the development of selective fibrinolytic substances, such as the tissue-type plasminogen activator (t-PA) or the anisoylated plasminogen-streptokinase activator complex (APSAC). Preliminary clinical data have shown that the coronary artery patency rate achieved after i.v. administration of t-PA or APSAC is higher than that after conventional treatment with streptokinase or urokinase. The incidence of severe bleeding complications is low and comparable in these studies. However, until myocardial salvage has been demonstrated with early i.v. fibrinolytic therapy in acute myocardial infarction in a placebo-controlled randomized trial, this therapeutic concept will still be unsettled.

    Notes: Abstract Objective To develop a scoring system for stratifying patients in intensive care units (ICUs) by risk of developing nosocomial pneumonia (NP), based on variables generally available in an ICU, and to determine the probability of a patient developing NP in the ICU. Design and setting A 2-year prospective cohort study conducted in a medical and surgical ICU. Patients 756 patients admitted to the ICU for 48 h or more were followed up until the development of NP or death or discharge from the ICU. Measurements and results 129 (17.1%) patients developed NP, 106 (14%) in the first 2 weeks. The following independent risk factors were identified by multivariate analysis: no infection on admission [relative risk (RR)=3.1, 95% confidence intervals (CI)=2.0 to 4.8]; thorax drainage (RR=2.1, 95% CI=1.2 to 3.5); administration of antacids (RR=2.1, 95% CI=1.4 to 3.1); partial pressure of oxygen (PO2)〉110 mmHg (RR=1.6, 95% CI=1.0 to 2.6); administration of coagulation factors (RR=1.8, 95% CI=1.0 to 3.2); male gender (RR=2.7, 95% CI=1.2 to 6.3); urgent surgery (RR=2.4, 95% CI=0.9 to 6.4); and neurological diseases (RR=4.2, 95% CI=1.9 to 9.4). To obtain a predictive risk index for NP, a scoring system was developed using a multivariate model. The probability of developing NP varied between 11.0% in the lowest risk group and 42.3% in the highest risk group. The patients' risk of acquiring NP was seven times higher in the highest score category (IV) than in the lowest one (I). Conclusions ICU patients can be stratified into high- and low-risk groups for NP. No infection on admission, thorax drainage, administration of antacids, and PO2〉110 mmHg were associated with a higher risk of NP during the entire 2-week period.

    Description / Table of Contents: Zusammenfassung In der späten Rehabilitationsphase nach Myokardinfarkt (13–24 Monate p. infarctum) wurde der pulmonale Gaswechsel neben hämodynamischen Parametern bei 23 Patienten unter Belastung untersucht. Der Belastungsverlauf der gemessenen Parameter gleicht dem Herz- und Lungengesunder. Die arteriellen Blutgaspartialdrucke ( $$Pa_{O2} , Pa_{CO2} $$ ) bleiben gegenüber den Ruhewerten unverändert oder zeigen nur geringe statistisch nicht signifikante Änderungen. Die alveoläre Ventilation $$\dot V_A $$ zeigt im Belastungsverlauf bei allen Patienten keine Unterschiede. Herzzeitvolumen $$\dot Q$$ , Atemminutenvolumen $$\dot V_E $$ , die Toträume, alveolo-arterielle Partialdruckdifferenzen der Atemgase ( $$AaD_{O_2 } , aAD_{CO_2 } $$ ) und Ventilations-Perfusionsverhältnis der Gesamtlunge $$\dot V_A /\dot Q$$ lassen jedoch erkennen, daß entsprechend der unterschiedlichen Arbeitskapazität der Patienten diese Parameter einen differenten Belastungsgang zeigen. Da sich die unterschiedliche Arbeitskapazität nach dem Verhalten von Herzzeitvolumen $$\dot Q$$ und gemischtvenösen Blutgaspartialdrucken aus der verschiedenen kardialen Funktion der Patienten erklären läßt, erscheint die Pathologie des pulmonalen Gaswechsels von der jeweiligen linksventriculären Funktion des Patienten abhängig. 12 der 23 untersuchten Patienten, die nach hämodynamischen Kriterien eine Belastungsinsuffizienz des Herzens zeigten, wiesen die ausgeprägtesten Änderungen des pulmonalen Gaswechsels auf. Die unterschiedliche Arbeitskapazität der Patienten ist allein von der kardialen Funktion begrenzt. Eine Leistungslimitierung durch Störung der Lungenfunktion ließ sich nicht beweisen.
    Notes: Summary After myocardial infarction in the late period of recovery (13–25 months p. infarctum) pulmonary gas exchange in 23 patients was measured besides as hemodynamic parameters during exercise. The parameters take a course similar to that of subjects without lung and heart diseases. Arterial blood gas tensions ( $$Pa_{O_2 } ,Pa_{CO_2 } $$ ) remain unchanged compared to resting values. Alveolar ventilation did show no difference in any of the patients. Minute ventilation $$\dot V_E $$ , the various dead spaces, alveolar-arterial gas differences ( $$AaD_{O_2 } , aAD_{CO_2 } $$ ) and ventilation-perfusion ratios of the whole lung $$\dot V_A /\dot Q$$ suggest however that these parameters show different courses according to the physical capacity of the patients. As the physical capacity of each patient is due to different cardiac functions taken by cardiac output and mixed venous blood gas tensions alterations of pulmonary gas exchange seemed to be dependent on the respective left ventricular function of the heart. Of the twenty-three patients, twelve with cardiac failure under exercise showed the most pronounced alterations in pulmonary gas exchange. Therefore, the different physical work capacity of the patients are determined only by cardiac function. No limitation of the productivity due to impeded lung function could be proved.

    Description / Table of Contents: Zusammenfassung 22 Patienten, die 1–2 Jahre zuvor komplikationslos einen Myokardinfarkt durchgemacht hatten, wurden bis an die Grenze ihrer Leistungsfähigkeit stufenweise ergometrisch belastet. Entsprechend der Belastbarkeit wurden die Patienten in vier Leistungsgruppen eingeteilt und die Anpassung der wichtigsten kardio-pulmonalen Funktionsparameter in jeder Gruppe getrennt verfolgt. Dabei waren in der Hälfte der Fälle bereits in Ruhe diskrete Insuffizienzzeichen nachweisbar. Bei der folgenden Ergometerbelastung stellten sich auch bei den übrigen Patienten in der ersten Belastungsstufe Insuffizienzzeichen ein.
    Notes: Summary From 22 patients in the late period of recovery from myocardial infarction, cardio-pulmonary data were recorded at rest and during exercise. The physical work was increased stepwise until patients reached their individual limit of exercise. According to the different work capacity four groups of patients were formed with the aim to demonstrate the adaption processes of cardio-pulmonary parameters until reaching the peak of work capacity. In one half of the patients we still found signs of cardial insufficiency at rest. After only slight physical work signs of cardiac insufficiency appeared also in the other half of patients.

    Notes: Abstract In patients with coronary artery disease coronary angiography plays an important role in the clinical decision-making process. However, it has been recognized that no simple relation exists between the visually or quantitatively evaluated severity of coronary artery stenoses and its effects on regional myocardial perfusion. This paper describes for the first time the development and application of a 3D technique that visualizes and quantifies regional myocardial perfusion parameters from biplane coronary angiograms by using the impulse response analysis technique. The 3D reconstructed coronary tree is automatically superimposed on the 3D perfusion image to generate and visualize an ‘integrated’ 3D image. The preliminary results in patients with critical coronary artery stenoses indicate that our combined 3D fusion image provides flow information from the major coronary arteries. This 3D fusion image may provide useful information in the management of patients with coronary artery disease.

    Description / Table of Contents: Zusammenfassung Obwohl 20% der Bevölkerung eine Pilzkolonisation des Gastrointestinaltrakts aufweisen, spielen Mykosen in der Initialphase der sekundären Peritonitis eine untergeordnete Rolle. Das Risiko für eine Pilzinfektion steigt nach ausgedehnten operativen Eingriffen, bei Breitspektrumantibiose, parenteraler Ernährung, Katheterismus, Immunsuppression etc. deutlich an. Innerhalb der letzten Jahre nahmen bei nosokomialen Infektionen Mykosen (überwiegend Candida spp.) deutlich zu. Intraabdominale Infektionen bei CAPD-Patienten werden in ca. 5% der Fälle durch Pilze verursacht. Bei Peritonitiden aufgrund Anastomoseninsuffizienz steigt die Inzidenz der Mykosen deutlich an, wobei die Letalität bis zu 80% beträgt. Im Verlauf der schweren Pankreatitis tritt bei bis zu 5% der Nekroseinfektionen eine invasive Mykose auf. Die Klinik der invasiven Pilzinfektion gleicht dem septischen Syndrom und ist in diesem Stadium mit einer Häufigkeit von bis zu 50% mit Fungämien vergesellschaftet. Da die meisten fakultativ pathogenen Pilze Teil der physiologischen Flora sind, ist die Interpretation kultureller Nachweise schwierig. Zur Diagnose einer invasiven Mykose können histopathologische Methoden sowie serologische Candidaantigen- und -antikörpernachweis hilfreich sein. Therapeutisch stehen mit Amphotericin B, Flucytosin und Fluconazol 3 hochwirksame Substanzen für die i.v.-Applikation zur Verfügung. Amphotericin B wird in einer Dosierung bis zu 1 mg/kg und Tag, in der liposomalen Galenik bis 3 mg/kg und Tag verabreicht. Flucytosin (0,15–0,2 g/kg und Tag) ist gut liquorgängig und hat in der Kombination mit Amphotericin B eine synergistische Wirkung. Fluconazol stellt bei empfindlichen Pilzen (Ausnahmen C. glabrata und C. krusei) in einer Dosierung von 200–800 mg/Tag eine ähnlich wirksame und nebenwirkungsärmere Alternative dar.
    Notes: Abstract Although there is a 20% yeast colonization in the gastrointestinal tract of the population, fungal infections appear only rarely in secondary peritonitis. The risk of severe mycosis increases after a major operation and when a patient is taking broad-spectrum antibiotics, is on total parenteral nutrition, is catheterized, and/or is immune-suppressed. In the past years the incidence of nosocomial fungal infections (usually Candida spp.) has risen significantly. Five percent of CAPD-related peritonitis is caused by fungi. In enteral anastomosis breakdown, invasive mycosis occurs more often, with an accompanying lethality of up to 80%. In severe pancreatitis, up to 5% of peripancreatic necrosis is infected with fungi. The clinical course of severe mycosis, like the septic syndrome, is associated with fungemia in up to 50% of cases. As most of the facultative pathogenic fungi are part of the physiological flora, it is difficult to interpret mycological cultures. In order to diagnose invasive fungal infections, histopathological techniques and serologic tests for antigens and antibodies are available. Three antifungal agents (amphotericin B, flucytosine, fluconazole) are available for intravenous administration. Amphotericin B is given at doses of up to 1 mg/kg per day, in liposomal galenism up to 3 mg/kg per day. Combining amphotericin B with flucytosine (150–200 mg/kg per day) a synergistic effect is reached. Fluconazole at a dosage of 200–800 mg per day represents an alternative with similar antifungal activity and lower side effects.
