    Description / Table of Contents: Abstract. Variations in anatomy of the bony and soft-tissue structures of the neck and facial cranium due to trauma, disease, or dysmorphic syndromes may lead to severe intubation problems. These patients are admitted for mandibulofacial and otolaryngologic surgery. It is important to inspect the patient's outer and inner pharyngeal structures carefully during preoperative assessment, as suggested by Mallampati [5]. The observer estimates the facility of intubation by inspection of the faucial pillars, soft palate, and uvula. Unfortunately, even careful examination does not predict every case of difficult intubation, so that unexpected problems may occur. There may also be difficulties in ventilating these patients with a face mask. Safe intubation is possible in these cases using the laryngeal mask airway (LMA) [1, 6, 7], laryngoscopy with a rigid optical aid [2], and the fibreoptic bronchoscope. Case report. We report a 14-month-old girl with Goldenhar's syndrome (oculo-auricular dysplasia) [3] who presented for soft-palate surgery. This syndrome belongs to the group of cranio-mandibular-facial malformations; the main symptoms are congenital unilateral malformations in the area of the 1st and 2nd branchial arches. The patient's jaw was hypoplastic with aplasia of the temporo-mandibular joint, which led to asymmetry of the lower face and an extremely short mandible. Additionally, we observed a large tongue in relation to the small jaw. Macrostomia is part of the syndrome, and may lead to underestimation of intubation problems. As the faucial pillars were visible but the uvula was masked by the base of the tongue, we assigned our patient to Mallampati class 2 [5]. Other findings in the syndrome can be malformations of the eyes, ears, heart, and spinal column. Our patient had complete atresia of the right outer ear and a subconjunctival lipoma. Due to these conditions, we expected a difficult intubation. Anaesthesia was induced with 250 mg methohexitone rectally and continued with halothane via a Rendell-Baker mask. After relaxation with vercuronium, laryngoscopy was performed. Due to the extremely short chin and relatively large tongue, it was impossible to visualise the vocal cords or epiglottis. Safe face-mask ventilation was also difficult. Therefore, we decided to introduce a LMA, which was easily done. Since reconstruction of the soft palate was not possible with a LMA, we used a fibreoptic bronchoscope to intubate the patient with a Vygon tube via the lumen of the LMA. Fixing the endotracheal tube with a long forceps, the LMA was easily removed. The LMA was successfully applied at a second procedure for a change of dressing. Discussion. In cases of difficult mask ventilation and intubation problems, the LMA improves the safety of both patient and the anaesthetist. Airway management with the LMA is easy and safe and without the risk of trauma caused by violent attempts to position an endotracheal tube by normal laryngoscopy when abnormal anatomy is present or unexpected problems occur. When a difficult intubation can be expected (e.g., in facial dysmorphic syndromes such as Goldenhar's syndrome, Pierre-Robin syndrome, or Franceschetti's syndrome) we recommend considering the LMA as a safe additional tool for airway management.
    Notes: Zusammenfassung. Anatomische Veränderungen, Verletzungen und Fehlbildungen im Hals- und Kopfbereich sind Gründe erschwerter bis unmöglicher konventioneller Intubation. Auch eine präoperative Einschätzung anhand der Einsehbarkeit von Tonsillen, Uvula und weichem Gaumensegel korreliert nicht immer mit dem späteren Intubationssitus. Wir berichten im folgenden über eine 14 Monate alte Patientin mit Goldenharsyndrom (Dysplasia oculo-auricularis), bei der ein Weichgaumenverschluß durchgeführt werden sollte. Das Syndrom gehört zum Formenkreis der kranio-mandibulo-fazialen Dysmorphien. Typisch sind Entwicklungsstörungen im Bereich des 1. und 2. Kiemenbogens mit Fehlbildung von Augen-, Ohren- und Kieferanlage. Die resultierende Hypoplasie des aufsteigenden Unterkieferastes mit Mikro-, Retrogenie kann zu erheblichen Intubationsproblemen führen. Nach Narkoseeinleitung mit Brevimethal rektal, Halothan und Vecuronium wurde eine Einstellung mit dem Laryngoskop vorgenommen. Im relativ zu kleinen Hypopharynx ließ sich die Glottis nicht einsehen. Wir entschieden uns eine Kehlkopfmaske einzulegen, was problemlos gelang. Da diese für die geplante Operation nicht belassen werden konnte, plazierten wir mit Hilfe einer Fiberoptik einen Vygon-Tubus durch den Ansatzschlauch der Kehlkopfmaske. Durch die Kombination von Kehlkopfmaske und fiberoptischem Endoskop als Intubationshilfsmittel waren die Atemwege der kleinen Patientin zu jeder Zeit gesichert. Wir empfehlen daher, bei zu erwartender schwieriger Intubation auch die Kehlkopfmaske grundsätzlich mit in Betracht zu ziehen.

    Description / Table of Contents: A 58-year-old man, admitted with one-vessel coronary disease and aortic valve insufficiency, was scheduled for cardiac surgery. He underwent single coronary bypass grafting and aorta ascendens replacement by a composite graft. During surgery he was monitored by a Swan-Ganz catheter, which had been inserted uneventfully via the right internal jugular vein. Six hours after completion of surgery we were unable to remove this catheter. Fluoroscopy showed intracardiac entrapment of the catheter. Rethoracotomy was performed, revealing entrapment by a suture. The purse-string suture was released, and the catheter was withdrawn without resistance.
    Notes: Zusammenfassung Bei einem 58jährigen Patienten wurden ein 1fach Koronarbypass und ein Aorta ascendens-Ersatz durch einen klappentragenden Conduit vorgenommen. Der vor dem Eingriff eingeschwemmte Swan-Ganz-Katheter ließ sich postoperativ nicht mehr entfernen. In der Röntgendurchleuchtung fand sich eine Bewegung der Herzsilhouette synchron zum Zug am Katheter. Als Ursache stellte sich eine intrakardiale Fixierung durch eine zu tief gefaßte Naht zur Versorgung der Vent-Einstichstelle heraus, die nach Rethorakotomie gelöst werden mußte. Der Katheter ließ sich danach problemlos entfernen.

    Description / Table of Contents: Conclusion The secretory pancreatic function is studied during the intravenous tolbutamide test in 30 normal persons and 13 diabetic patients. For the evaluation of the secretion rate certain measures were developed. These measures showed significant differences in both groups of the absolute values of amylase (P ≦ 0,27%), of amylase in percentage of secretion-volume and of absolute carboxypeptidase secretion (0,27〈P ≦ 5%). The results indicate that the excretory pancreatic response as tested by tolbutamide is better in normal individuals than in diabetics.

    Description / Table of Contents: Summary To obtain a better assessement of subclinical diabetics, the intravenous tolbutamid-test-curves of 59 diabetics and 80 nondiabetics were evaluated by different methods. Some new parameters for the discrimination of diabetics and nondiabetics were presented. A graphical procedure was recommended for determinating a practicable discriminatory parameter. This parameter contains all original information of the tolbutamide-curve and can be obtained in 1–2 minutes. It completely differentiates the two groups. Using the parameter in a great number of cases, 0,3% false positive and 0,2% false-negative results are statistically expected. The results of theT 3-tests in a groupe of 28 „big-baby-mothers“ and 16 relatives of diabetics demonstrated the indirect validity of the test for detecting prediabetics.
    Notes: Zusammenfassung Als Beitrag zum Problem der Entdeckung latent-diabetischer Zustände wurde die Trennschärfe des Tolbutamid-Tests bei verschiedenen Auswertungsmethoden an Hand der Kurven von 59 Diabetikern und 80 Stoffwechselgesunden untersucht. Neue Kriterien zur Unterscheidung stoffwechselgesunder und diabetischer Tolbutamid-Test-Kurven wurden dargestellt, darunter ein graphisches Verfahren zur Ermittlung eines Trennmaßes (T3). Dieses Trennmaß enthält alle Meßinformationen der Kurve und kann in etwa 1–2 min pro Fall ermittelt werden. Am vorliegenden Material ermöglicht es eine vollständige Trennung beider Gruppen. Unter Zugrundelegung der beobachteten Häufigkeitsverteilung läßt sich die Zahl der möglichen Fehleinstufungen mit 0,3% falsch-positiven und 0,2% falsch-negativen Resultaten schätzen. Die Anwendung des T3-Tests bei einem auf Prädiabetes suspekten Kollektiv von 28 „Big-Babymüttern“ und 16 Familienangehörigen von Diabetikern ergab indirekt einen Validitätsnachweis des Verfahrens zur Erkennung latent diabetischer Zustände.

    Description / Table of Contents: Summary Triglyceride content of 81 human liver biopsies, obtained at laparoscopy or by percutaneous needle puncture, was quantitatively measured by chemical means and expressed as a percentage of wet weight. Depending on the degree of fat infiltration, triglyceride concentration varied from 0,5–24%. The degree of fat infiltration was histologically estimated by the convential method of grading and by a morphometric point system basing on the Delesse principle, which states that the volume fractionV i of a componenti in the tissue can be estimated by measuring the area fractionA i of a random section occupied by transsections ofi; the results obtained by this method are expressed as percent. The chemically measured triglyceride content and histologically resp. stereologically estimated degree of fat infiltration were compared and correlated statistically. There was a significant correlation between triglyceride content and various histological and stereological estimates of fat infiltration; paraffin sections proved more reliable than frozen sections for estimating the degree of fat infiltration. The correlation between the chemical triglyceride content and the results of estimating by the point system is a hyperbolic one, when expressed in mathematical terms. This hyperbolic function becomes quite clear considering the fact that weight percent was compared with volume percent. By means of mathematical transformations the correlation between the results of the chemical and the stereological method could be brought into a linear system; so it was possible to calculate single, partial and multiple correlation coefficients. Furthermore the relation between the lipid fractions of blood plasma, body weight, some laboratory data and the triglyceride content of the biopsies were examined. The only significant correlation was found between body weight and fat infiltration of the liver. On the basis of the results obtained a formula was developed for calculating the chemical triglyceride content from the stereologically estimated values.
    Notes: Zusammenfassung Die zwischen dem chemisch bestimmten Triglyceridgehalt und dem stereologisch mit Hilfe des Punkt-Treff-Verfahrens geschätzten Verfettungsgrad in Leberpunktionszylindern bestehenden signifikanten Korrelationen werden eingehend geprüft, theoretisch begründet und in einer Formel mathematisch zusammengefaßt. Entwicklung einer Schätzformel, die es gestattet, aus den Punkt-Treff-Werten auf den tatsächlichen Triglyceridgehalt zu schließen.

    Description / Table of Contents: Summary Kidneys not responding to antidiuretic activity deliver rising amounts of osmotically free water during an increasing tubular solute load. In nephrons with normal response to ADH, however, a rising tubular solute load (Cosm) results in an increasing or constant reabsorption of osmotically free water ( $$Tc_{H_2 O} , Tm^c _{H_2 O} $$ respectively). We studied the reabsorption of osmotically free water in 14 hydropenic patients under forced osmotic diuresis and exogenous antidiuretic activity. The patients were recovering from acute renal failure of different origin (acute anuric glomerulonephritis excluded). A constant net diffusion of free water could be demonstrated even in the very early diuretic phase. Control studies during the later course of the diuretic stage showed an increasing $$Tmc_{H_2 O} $$ together with a rise in GFR. These results show, that the functioning nephrons after acute renal failure do respond in a normal manner to antidiuretic activity. Two patients only out of 14 did not respond normally to ADH. The reason was transient hypercalcaemia and chronic obstructive pyelonephritis respectively. In both instances conditions different from the acute renal failure accounted for the lacking response to antidiuretic activity. The diminished concentrating ability after acute renal failure is due to the decreased reabsorption of sodium in the ascending limb of Henle's loop, to the lowered sodium concentration in the medulla of the kidney and to an increased tubular solute load. The results give support to the hypothesis that the re-establishment of glomerular filtration, the rising urinary flow and the improving concentrating ability after acute renal failure are all initiated by the recovery of tubular sodium reabsorption.
    Notes: Zusammenfassung An 14 Patienten wurde die Harnkonzentrierung nach akutem Nierenversagen untersucht. Unter maximaler osmotischer Diurese und gleichzeitiger maximaler antidiuretischer Aktivität ließ sich bereits bei der ersten Untersuchung wenige Tage nach Wiedereinsetzen der Diurese eine mit zunehmender osmolarer Clearance konstante oder ansteigende Rückdiffusion von osmotisch freiem Wasser nachweisen. Ein Patient wies eine vorübergehende Störung der Rückdiffusion osmotisch freien Wassers unter einer Hypercalcämie auf. Eine weitere Patientin zeigte eine verminderte Wasserrückdiffusion wie bei einem Diabetes inspidus renalis, die weniger auf das akute Nierenversagen selbst als vielmehr auf morphologische Veränderungen des Nierenparenchyms, die bereits vor dem akuten Nierenversagen bestanden haben, zurückzuführen war. Die Konzentrationsschwäche nach akutem Nierenversagen ist auf die herabgesetzte tubuläre Natriumrückresorption, eine verminderte medulläre Natriumkonzentration sowie auf die osmotische Harnstoffdiurese zu beziehen. Hinweise auf eine verminderte Ansprechbarkeit distaler Nephronabschnitte gegenüber antidiuretischer Aktivität als unmittelbare Folge des akuten Nierenversagens ergaben sich aus unseren Untersuchungen nicht. Die Ergebnisse stehen in Übereinstimmung mit der Hypothese, daß das Wiedereinsetzen der glomerulären Filtration, der Diurese und die Rückerlangung einer normalen Konzentrationsfähigkeit von der Wiederherstellung der Natriumrückresorption im aufsteigenden Schenkel der Henleschen Schleife ausgehen.
