    Notes: Summary Among a total of 2147 patients admitted to our hospital for acute myocardial infarction between 1978 and 1987, three young patients aged 24, 29, and 39 years had previously been treated for Hodgkin's disease. Staging laparotomy, including splenectomy, had been performed in all three patients. Two patients had both mediastinal irradiation (21 and 27 months before infarction) and chemotherapy. In the first patient, postmortem histologic examination of the coronary arteries revealed fibrotic changes, which were probably induced by radiotherapy. In our second patient, myocardial infarction developed 5 days after vinblastine treatment; early angiography showed thrombotic occlusion of the proximal right coronary artery, which was recanalized using the diagnostic Sones catheter. Subsequent angiography revealed normal coronary arteries. This is, to our knowledge, the first case of documented coronary artery thrombosis after treatment with vinca-alkaloids. In our third patient, neither mediastinal irradiation nor chemotherapy had been performed prior to myocardial infarction. However, a marked increase in platelet counts following splenectomy was observed in this patient. The role of radiotherapy, chemotherapy, and splenectomy with consecutive thrombocytosis as a third possible pathogenic factor for subsequent development of myocardial infarction is discussed.

    Notes: Abstract Visceral leishmaniasis (kala-azar) affecting HIV-infected patient is being reported in increasing frequency. A 40-year-old German bisexual patient with full-blown AIDS is described who presented with Kaposi's sarcoma, epigastric pain, diarrhea, and weight loss but without fever.Leishmania amastigotes were initially found in biopsies from stomach, duodenum, and a cutaneous Kaposi's sarcoma lesion but were later also recovered from bone marrow and lymph node. The patient received three courses of a combination of pentavalent antimony and interferon-γ. In addition to the common side effects such as fever, thrombocytopenia, and elevated amylase and lipase, a vivid progression of the Kaposi's sarcoma was noted. Tumor progression was temporally closely associated with treatment with interferon-γ. Because this phenomemon has also been observed in other patients, we advise caution when using interferon-γ in patients with Kaposi's sarcoma.

    Notes: Abstract Two patients developed renal Fanconi syndrome (RFS) after intensive long-term chemotherapy for metastatic Ewing sarcoma and disseminated neuroblastoma. Whereas RFS was diagnosed in patient 1 before he developed osteomalacia, patient 2 experienced severe rickets and growth retardation. Renal function studies revealed slight glomerular impairment and severe tubular defects leading to increased excretion of glucose, amino acids, inorganic phosphate and low molecular weight proteins, indicating proximal tubular damage. Patient 2 additionally showed distal tubular dysfunction with acidosis and diminished concentrating capacity. Renal biopsy in patient 1 revealed marked proximal tubular defects without interstitial lymphocytic infiltration. In both patients renal damage could most likely be ascribed to previous ifosfamide (IFOS) therapy. Our patients showed no improvement in renal function after cessation of IFOS treatment, indicating a poor prognosis of once established RFS after IFOS therapy. Measurement of tubular reabsorption capacities provides exact information on the extent of tubular toxicity induced by IFOS and may be used to monitor IFOS treated patients.

    Notes: Summary The secretory aspartic proteinases ofCandida albicans andC. tropicalis are potential factors for virulence produced during infection. By indirect immunofluorescence, we have demonstrated proteinase antigen on elements of both species in deparaffinized tissue sections derived from clinical cases of mucosal and deep-seated candidiasis. Occasionally, we observed a halo of fluorescence in the close vicinity of candidal cells, which may reflect secretion of the enzyme. In kidneys, a ring of amorphous fluorescent material surrounding candidal colonies may illustrate alkaline denaturation of secreted enzyme within a pH gradient, which is generated by the fungus. Our findings support the view that candidal proteinase may be a diagnostically relevant antigen.

    Notes: Summary Renal biopsy specimens of 40 patients with recent-onset insulin-dependent diabetes mellitus treated with cyclosporine (CSA) for 6–29 months were examined. Cyclosporine-associated chronic vascular interstitial toxicity of moderate intensity was found in 10 patients (25%). The most prominent lesions were interstitial fibrosis and tubular atrophy. Arteriolopathy was less pronounced and glomerular damage unremarkable. A significant correlation exists between the extent of tubular atrophy and CSA trough whole blood levels. These data indicate that the development of CSA-associated chronic nephropathy is dose-dependent.

    Description / Table of Contents: Summary So far two methods for prolonging the tolerance of renal ischemia are available: 1) surface cooling with crushed ice and 2) perfusion cooling with an extracellular-like solution. Both methods use only the principle of reducing metabolism through cooling. While rewarming during surgery the ischemic protection is lost, or the kidney must be cooled once again. Therefore, a new preservation solution should reduce energy consumption due to its composition in addition to cooling. For open heart surgery, the HTK solution by Bretschneider is already used clinically. In 71 dog kidney experiments, the ischemic time kidneys could tolerate was prolonged by this solution from 15 to 120 min at 35°C and from 45 to 360 min at 25°C. After 2h of ischemia at 30°C glomerular filtration rate was about 20 ml/min · 100 gww within 3 h of reperfusion. After six postoperative days the filtration rate was 40 ml/min · 100 gww. No ischemic damage could be recognized by histological investigations. The clinical effectiveness of this method was shown in 7 clinical applications. Ischemic duration lasted up to 113 min, and blood creatinine was between 0.8 and 2.4 mg% at the 6th postoperative day. Use of this preservation technique thus leads to improved kidney function immediately following operation. Longer ischemia can be tolerated by a kidney thus protected, and using this technique excellent visibility can be achieved during intrarenal surgery, simplifying, for example, tumor extirpation.
    Notes: Zusammenfassung Zur Verlängerung der renalen Ischämie stehen bisher zwei Verfahren zur Verfügung: 1) eine Oberflächenkilhlüng mit Eis and 2) eine Perfusionskühlung mit einer extrazellulären Losung. Beide Methoden nutzen nur das Prinzip der Stoffwechselsenkung durch Kühlung. Während der Wiedererwärmung bei der Operation geht der Ischämieschutz verloren oder die Niere muß erneut gekiihlt werden. Deshalb sollte eine neue Protektionslösung den Energieverbrauch zusätzlich zur Kühlung auch durch ihre Zusammensetzung senken. Bei offenen Herzoperationen wird die HTK-Lösung nach Bretschneider bereits klinisch angewendet. In 71 Experimenten an Hundenieren wurde die Ischämiezeit durch diese Lösung von 15 auf 120 min bei 35°C and von 45 auf 360 min bei 25°C. verlängert. Nach 120 min Ischämie bei 30°C betrug die glomeruläre Filtrationsrate ca. 20 ml/min 100gFG innerhalb von 3 h Reperfusion. Nach 6 Tagen postoperativ war die GFR wieder 40 ml/min 100gFG. Es konnte kein ischämischer Schaden durch histologische Untersuchungen mehr festgestellt werden. Der klinische Nutzen dieser Methode konnte in 7 klinischen Anwendungen gezeigt werden. Die Ischamiezeit betrug bis zu 113 min and das Kreatinin lag zwischen 0,8 and 2,4 mg% am 6. postoperativen Tag. Dieses Protektionsverfahren führt also zu einer verbesserten Nierenfunktion in der postoperativen Phase. Eine längere Ischämiezeit wird von der Niere vertragen, and unter Anwendung dieser Technik wird eine ausgezeichnete Übersichtlichkeit während der Nierenoperation erreicht, was eine radikale Tumorexzision erleichtert.
