    Description / Table of Contents: Zusammenfassung Verschiedene Untersuchungen über die Compliance oder Therapiedisziplin von Patienten haben gezeigt, daß zwischen 20 bis 50% der Patienten vor allem in der Langzeittherapie die ärztlichen Verordnungen nicht oder nur ungenügend befolgen. Die Non-Compliance ist damit seit der Einführung wirksamer Medikamente insbesondere in der Behandlung der essentiellen Hypertonie, bei Fettstoffwechselstörungen, sowie bei Patienten unter tuberkulostatischer Therapie oder prophylaktischer Chemotherapie zu einem der wichtigsten therapielimitierenden Faktoren geworden. Die Einnahmedisziplin verschlechtert sich im Laufe der Behandlung zusehends. In den ersten vier Monaten ist mit einem Abfall der Compliancerate um 30% zu rechnen, nach 5 Jahren ist nur noch ein Fünftel bis ein Viertel der Patienten therapietreu. Die Zuverlässigkeit der Patienten läßt sich mit indirekten Bestimmungsmethoden wie Patientenbefragung, Pillenzählen oder aufgrund der Therapiewirkungen abschätzen. Eine genaue Ermittlung der Compliancerate erfordert die Bestimmung der Medikamente oder Markersubstanzen im Serum oder Urin. Die Ergebnisse von Untersuchungen über compliancebestimmende Faktoren sind zum Teil widersprüchlich. Als gesichert kann hingegen gelten, daß psychische Erkrankungen insbesondere Schizophrenie, ein komplexes Therapieschema mit hoher täglicher Tablettenzahl, Therapien, welche eine Änderung von Lebensgewohnheiten erfordern, eine langdauernde Behandlung und ungenügende, schlecht organisierte Nachkontrollen mit langen Wartezeiten für den Patienten eine schlechte Therapiedisziplin zeigen. Im weiteren beeinflussen das Krankheitsbewußtsein sowie die Einstellung der Familie das Einnahmeverhalten der Patienten. Compliancefördernde Maßnahmen richten sich nach den Faktoren, welche die Therapietreue der Patienten negativ beeinflussen. Entsprechend sollte durch eine Verwendung von „Slow-Release“-Präparaten die tägliche Tablettenzahl möglichst klein gehalten werden. Bei mehreren Tabletteneinnahmen pro Tag ist ein schriftlicher Verordnungszettel („aide-memoire“) von Nutzen. Durch regelmäßige engmaschige Nachkontrollen mit festen Terminen und kurzen Wartezeiten sollte in der Langzeittherapie die „drop-out“-Rate reduziert werden. Eine zusätzliche Betreuung durch paramedizinisches Personal zeigt ebenso wie der Einsatz von Therapiegruppen vor allem in der Betreuung von übergewichtigen Patienten und Hypertonikern einen günstigen Effekt auf die Compliance. Die Beteiligung des Patienten an der Behandlung und Überwachung seiner Erkrankung z.B. durch Blutdruckselbstmessung bei den wenig symptomatischen Hypertonikern führt zu einer deutlichen Verbesserung der Einnahmedisziplin. Bei Therapien, welche eine Änderung von Lebensgewohnheiten erfordern (Diät, Alkoholabstinenz, Nikotinabstinenz u.a.), sollte die Familie (Ehefrau) in den Therapieplan miteinbezogen werden. Die Patientencompliance verdient aufgrund ihrer praktischen Bedeutung (Nichterreichen des Therapieziels, Beeinflussung von Ergebnissen der Arzneimittelforschung, unnötige Kosten) eine vermehrte Beachtung im Rahmen der Patientenbetreuung. Compliancevermindernde Faktoren sollten möglichst eliminiert und Maßnahmen zur Verbesserung der Therapiedisziplin ergriffen werden.
    Notes: Summary Several studies concerning compliance or drug adherence of patients have shown, that between 20–50% of the patients in particular during long term therapy do not or only insufficiently follow doctor's advice. Thus, since the introduction of potent drugs, non-compliance has become one of the most important therapy limiting factors in particular in the management of essential hypertension, disorders of lipid metabolism, tuberculosis and chemo-prophylaxis. Compliance decreases during treatment. During the first four months a decline of compliance rate of 30% must be expected, after five years only 20–25% of the patients are still compliant. Patients' cooperation may be estimated by indirect methods such as patient interview, pill-counting or therapeutic outcome. An exact determination of compliance requires measurements of blood levels or urinary excretion of the medicaments or marker. The results of studies about the determinants of compliance are conflicting. However, it seems to be proved, that a psychiatric diagnosis in particular schizophrenia, a complex therapeutic regimen with a high number of daily tablets, therapies which include a behavioral change, longterm therapy and a inefficient follow-up system with long waiting time for the patient are associated with non-compliance. In addition, patients perception of the disease and family support are influencing drug adherence. Compliance improving strategies were derived from the determinants which diminish patients' drug adherence. By using slow release medicaments the number of daily tablets should be minimalized. If several tablets must be taken daily an “aide-memoire” may be useful. The drop-out rate should be reduced by regular scheduled follow-up visits with short waiting time. In addition, follow-up care by a nurse or a diet adviser as well as therapy groups show a compliance improving effect in particular in patients with overweight or hypertension. The participation of the patient in therapy and follow-up for instance by blood pressure selfmeasurement in the mostly symptomless hypertensives increases markedly drug adherence. In therapies which necessitate behavioral changes (diet, alcohol abstinence, stop of smoking) the family should be integrated in the therapeutical procedure. Because of its practical importance (unsatisfactory therapeutical outcome, influence on results of pharmacological studies, costs) compliance should be taken into account in patient's care. Compliance decreasing factors should be eliminated and strategies for improving drug adherence should be performed.

    Notes: Abstract In primary aldosteronism the type of adrenal lesion was correctly identified in 28 of 40 patients (70%) by standard adrenal scintigraphy. Suppression scintigraphy did not improve the validity of the method. In all patients the diagnosis was confirmed by surgery (unilateral adenoma n=32; bilateral adrenal hyperplasia n=11). False classification of the adrenal lesion(s) by standard scintigraphy was mostly due to a bilateral adrenal isotopic uptake in patients with an unilateral aldosteronoma. However, a substantial number of these patients (6 of 11 patients) received long-term spironolactone treatment prior to the examination. Thus, in primary aldosteronism adrenal changes induced by chronic spironolactone administration are probably a major cause for incorrect differentiation between adenoma and hyperplasia by adrenal scintigraphy.

    Notes: Abstract  Background: The object was to evaluate the long-term effectiveness of strategies for managing the aortic root and distal aorta in type A dissections. Methods: From 1990 to 1999, 50 patients (32 men (64.07%); 18 women, (36.0%); mean age 57.4 ± 11.1 years) underwent operation for ascending aortic dissection. Surgical strategies included aortic root replacement with a composite graft (21/50; 42.0%), valve replacement with supracoronary ascending aortic graft (3/50, 6%), and valve preservation or repair (26/50; 52.0%). Results: Overall hospital mortality rate was 18.0%. Follow-up was completed for 47 patients (94.0%) and ranged from 1 month to 10.5 years (mean 28.8 months). Actuarial survival for patients discharged from the hospital was 84% at 1 year, 75% at 5 years, and 66% at 10 years. There was no significant difference between the various procedures regarding mortality, neurological complications, long-term survival, and proximal reoperations. The ascending aorta alone was replaced in 8 of 50 patients (16%), ascending and hemiarch in 30 of 50 patients (60%), and arch and proximal descending aorta in 12 of 50 patients (24%). Hospital mortality (11.5%, 20.0%, and 16.7%, respectively; p 〉 0.05) and 5- and 10-year survival (p 〉 0.05) were not statistically dependent on the extension of the resection distally. Residual distal dissection was not associated with a decrease in late survival. With regard to emergency surgery (36/50) there was no significant difference in hospital mortality (p 〉 0.05) and 5-year survival (p 〉 0.05) between those who had undergone coronary angiography (19/36; 52.8%) on the day of surgery with those who had not (17/36; 47.2%). Conclusions: Preservation or repair of the aortic valve can be recommended in the majority of patients with type A dissection. Distal extension of the resection does not increase surgical risk. Residual distal dissection does not decrease late survival. Preoperative coronary angiography may not affect survival in patients undergoing emergency surgery. (J Card Surg 2004;19:240-245)

    Notes: Abstract  Background: The Edwards MIRA™ mechanical heart valve is designed to optimize hemodynamics, reduce thrombogenicity, and avoid mechanical failure with a special hinge mechanism. The purpose of the study was to investigate the clinical performance and postoperative hemodynamic results of the first European patients receiving Edwards MIRA™ mechanical heart valves. Methods: From March 1998 to March 1999 a total of 54 Edwards MIRA™ valves model numbers 3600 (aortic, n = 44) and 9600 (mitral, n = 10) were implanted in 52 (36 male, 16 female; mean age 61 ± 10.1 years) consecutive patients undergoing mechanical valve replacement in a prospective study. Follow-up of the patients including physical examination, ECG, blood tests, and Doppler were performed prior to discharge, at 6 months, at 1 year, and at least 2 years postoperatively. Results: Through October 2001 a total of 172 follow-up examinations were completed (51 patients at discharge, 46 patients at 6 months, 43 patients at 12 months, 32 patients at 2 years or beyond). All patients were in NYHA class I and II at the 6-month and 2+-year follow-up. All the patients stated an improved quality of life. Hospital mortality was 1.9%. There were no complications related to anticoagulation. Mean international normalized ratio at 6 months was 3.2 (range 1.9 to 4.3); lactate dehydrogenase was slightly increased with 264 ± 103 U/L on average (normal value 80 to 240 U/L). No signs of valvular dysfunction or paravalvular leakage were observed. Mean pressure gradients were related to valve diameter: after mitral valve replacement (size 27, 29, 31 mm: 4.8, 3.2, 2.1 mmHg); after aortic valve replacement (size 19, 21, 23, 25 mm: 12.1, 13.1, 9.3, 8.2 mmHg). Conclusions: These preliminary data suggest good hemodynamic function and a low rate of valve-related complications of the Edwards-MIRA™ mechanical prosthesis. (J Card Surg 2004;19:226-231)

    Notes: Zusammenfassung Wie sich aus einem großen, statistisch bearbeiteten klinischen Material ergibt, sprechen hohe Basophilenwerte eindeutig gegen eine Hyperthyreose und erniedrigte Basophilenwerte eindeutig gegen ein Myxödem. Auf Grund der Beeinflussung der Basophilenzahl durch außerhalb der Schilddrüsenwirkung gelegene Faktoren sind jedoch niedere Basophilenwerte zur Stellung der Hyperthyreosendiagnose bzw. erhöhte Basophilenwerte zur Stellung der Myxödemdiagnose nur beschränkt zu gebrauchen. Die Bestimmung der Basophilenzahl scheint zur Beurteilung des Therapieerfolges brauchbar.

    Description / Table of Contents: Zusammenfassung Bei vier Patienten mit Phäochromocytom wurde zur Lokalisation eine Szintigraphie mit131J-meta-iodobenzylguanidin durchgeführt. Ein unilaterales adrenales Phäochromocytom wurde bei drei der Patienten gefunden, während eine Patientin mit malignem Phäochromocytom eine dissiminierte Tumoraussaat zeigte. Die Ergebnisse dokumentieren, daß die Szintigraphie mittels131J-meta-iodobenzylguanidin eine zuverlässige und einfache Methode zur Lokalisation adrenaler und extraadrenaler, sowohl benigner als auch maligner Phäochromocytome darstellt.
    Notes: Summary In four patients with pheochromocytoma, scintigraphy with131I-meta-iodobenzylguanidine was performed to localize hyperfunctioning adrenergic tissue. In three patients unilateral adrenal pheochromocytoma was found, whereas one patient with a malignant pheochromocytoma showed multilocular dissemination. The results document that scintigraphy with131I-meta-iodobenzylguanidine seems to be a safe and reliable method of detecting adrenal and extra-adrenal pheochromocytomas, both benign and malignant.
