    Notes: : The Pittsburgh District, U.S. Army Corps of Engineers, is responsible for operating two multipurpose reservoirs in the 7384 square mile (19198 square kilometer) Monongahela Basin. A third reservoir, presently under construction, will soon be operating. The real-time forecasting of runoff for operational purposes requires simulation of snow accumulation and snowmelt throughout the Basin during the winter season. This article describes capabilities of SNOSIM, a model being developed for performing such simulation. The application of this model as part of a comprehensive system of water control software, and some initial simulation results are presented.

    Notes: Abstract The detection of buried anti-personnel mines (APMs) is widely considered as a problem which may only be solved with a combination of two or more complementary sensors. We present processing and fusion results obtained from a multisensor data set, acquired with a pulse induction metal detector (MD), a pulsed ultra wide band ground penetrating radar (GPR) and a 3–5μ thermal infra-red (IR) camera. Various types of soils, clutter objects and burial conditions were recorded. Anti-personnel mines included minimum metal mines as well as mines with a significant metal content. We use a special projection to map a 3D GPR data cube, with time or depth as vertical co-ordinate, into a horizontal plane view 2D image. Object contours are then derived, based on an edge extraction method, followed by an automatic detection of circular shapes with a Hough-transform. In the association step, the stand-off IR image, the metal detector and GPR images and related detections are mapped onto a common cartesian grid on the ground surface. Detection results are fused on a decision level, using a Bayesian approach. Our results indicate that the GPR performance approximately matches that of the metal detector. With both sensors all metallic mines and around 60% of the minimum metal mines were detected. In the case of two false alarms per square meter combined detection probability clearly exceeds single sensor performance.

    Description / Table of Contents: Résumé Le métabolisme postopératoire est caractérisé par une augmentation de la demande énergétique et de la perte azotée. Là ou les mécanismes d'autorégulation sont capables d'assumer les besoins energétiques augmentés par la lipolyse sans problème endogène la perte azotée concerne principalement les protéines importantes aussi bien sur le plan fonctionnel que sur le plan métabolique. Pour prévenir la déperdition azotée postopératoire, une alimentation parentérale hypocalorique est suggérée. Elle consiste en un apport adéquat d'amino:acide à raison de 1.2–1.5 g/kg poids/jour et un apport d'hydrates de carbone n'excédant pas 150–200 g par 24 heures. D'après la propre expérience de l'auteur cet apport peut être effectué à l'aide de substituts glucosés comme les polyoles car ils ne perturbent pas considérablement le mécanisme autorégulatoire endogène et ils aident aussi la gluconéogénèse si bien que les aminoacides peuvent être évités. En procédant à l'analyse d'une période de 6 ans au cours de laquelle une alimentation parentérale postopératoire hypocalorique d'une part et une alimentation normale d'autre part furent pratiquées, l'auteur croit pouvoir affirmer que l'alimentation hypocalorique présente autant d'avantages que l'alimentation hypercalorique qui est plus onéreuse et plus absorbante.
    Abstract: Resumen El metabolismo postoperatorio se caracteriza por aumento en la demanda energética y en la pérdida de nitrógeno. En tanto que el mecanismo autorregulatorio es capaz de atender la demanda energética a través de incremento en la lipolisis sin inducir problemas endógenos, la pérdida de nitrógeno afecta principalmente a proteínas funcional y metabólicamente importantes. Justamente con el objeto de prevenir estas pérdidas proteicas durante el período postoperatorio agudo, se sugiere la nutrición parenteral hipocalórica. El concepto de la nutrición hipocalórica implica una sustitución adecuada de aminoácidos a razón de 1.2–1.5 gramos/kg de peso/día y una provisión de bajas cargas de carbohidrato que no superen los 150 a 200 gramos por día. De acuerdo a nuestras propias experiencias, esta provisión de carbohidrato puede ser favorablemente realizada con sustitutos de la glucosa, tales como los polioles, porque estos sustratos no alteran los mecanismos autorregulatorios endógenos en forma apreciable y dan soporte a la gluconeogénesis hepática de tal manera que los aminoácidos pueden ser preservados. Al analizar un período de 6 años de uso tanto de nutrición parenteral hipocalórica como de nutrición parenteral con adecuado soporte calórico, creemos tener toda la razón para considerar que la nutrición hipocalórica definitivamente no es menos beneficiosa que la nutrición parenteral de alto valor calórico, la cual, en cuanto a su aplicación y monitoría, es bastante más costosa y consume mayor cantidad de tiempo por parte del personal que la administre.
    Notes: Abstract Postoperative metabolism is characterized by increased energy demand and nitrogen loss. Whereas autoregulatory mechanisms are able to meet the energy needs by enhanced lipolysis without endogenous problems, nitrogen loss mainly affects functionally and metabolically important proteins. In order to prevent these protein losses during the acute postoperative period, hypocaloric parenteral nutrition is suggested. The concept of hypocaloric nutrition consists of adequate amino acid substitution of 1.2–1.5 g/kg body weight per day and a low-dosed carbohydrate supply not to exceed 150–200 g per day. According to our own experience, this carbohydrate supply is best done with glucose substitutes like polyoles, since these substrates do no greater damage to the endogenous autoregulatory mechanism and give additional support to hepatic gluconeogenesis so that amino acids can be spared. Analyzing a 6-year period of using both hypocaloric and caloric-adequate postoperative parenteral nutrition we believe that hypocaloric nutrition is as beneficial as higher caloric parenteral nutrition, which in its application and monitoring is more expensive and time-consuming.

    Description / Table of Contents: Zusammenfassung. 37 Patienten mit chronischem Pilonidalsinus wurden in dem Zeitraum von Mai 1993–Mai 1997 nach Totalexcision und Revision der Steißbeinspitze mit einer Lappenplastik nach Dufourmentel versorgt. Nachuntersucht wurden 32 Patienten. Bei 3 Patienten entwickelte sich postoperativ ein punktionswürdiges Wundserom, bei 2 Patienten kam es zu einer Sekundärheilung. Die durchschnittliche Krankenhausverweildauer lag bei 6,3 Tagen, die durchschnittliche Arbeitsunfähigkeit bei 2,5 Wochen. Die Methode ist einfach durchführbar, Rezidive sind in Übereinstimmung mit der Literatur nicht bekannt.
    Notes: Summary. Thirty-seven patients with chronic sinus pilonidalis were treated after total excision by Dufourmentel flap. We saw seroma complications in three and wound infections in two cases. Patients stayed in hospital 6.3 days on an average and were able to work after 2.5 weeks. The method is easy to use. We have not seen a return to sinus problems in any of this cases.

    Description / Table of Contents: Zusammenfassung 37 Patienten wurden 6—62 Monate nach Anlage einer biliodigestiven Anastomose — 18 Choledocho- und 19 Hepaticojejunostomien nach Roux-en-Y — nachuntersucht. Die hepatobiliäre Sequenzszintigraphie zeigte bei 26 Patienten sowohl einen unbehinderten Galleabfluß als auch eine normale Funktion der ableitenden Jejunumschlinge. 6 Patienten hatten ein Abflußhindernis im Bereich des Ductus oder der Anastomose gepaart mit cholangitischen Beschwerden und laborchemischen Cholostasezeichen. Bei 5 Patienten wurden Funktionsstörungen der abführenden Jejunumschlinge beobachtet, die zwar mit klinischen Beschwerden einhergingen, jedoch nur in 1 Fall zur Cholostase führten.
    Notes: Summary 37 patients with bilio-digestive anastomosis — 18 choledocho- and 19 hepatico-jejunostomies Roux-en-Y — had been followed up for 6–62 months. Hepato-biliary sequential scintigraphy showed in 26 patients both unimpeded bile passage and normal function of the jejunal loop. 6 patients had stenosis in the common bile duct or the anastomosic region with cholangitis and cholostasis. In 5 patients we observed an impaired function of the jejunal loop. Though all of these patients had clinical symptoms only one patient developed cholostasis.

    Notes: Abstract Purpose: The aim of this prospective study was to evaluate the feasibility, safety, and efficacy of sequential transarterial chemoembolization (TACE) for patients with unresectable advanced hepatocellular carcinoma (HCC). Methods: Twenty-one consecutive patients with unresectable T3 and T4 HCC were treated by sequential TACE (median time interval between treatments 7 weeks) up to six times with an emulsion of lipiodol, epirubicin, and cisplatin. All TACE procedures were performed as unilobar or whole-liver chemoembolization. Results: An average of 3.9 TACE procedures were performed per patient. One primary and two secondary technical failures occurred. No procedural death was observed. After exclusion of the patient with the primary technical failure and 3 patients with extrahepatic disease, the survival rates for the remaining 17 patients at 6, 12, 18, and 24 months were 70.6%, 52.9%, 44.1%, and 33.1%, respectively. Conclusion: Sequential TACE is a safe procedure in patients with unresectable advanced HCC and feasible in most cases. It seems to prolong the survival time compared with historical series of untreated patients.

    Description / Table of Contents: Abstract The deepithelialized “turn-over-flap” is a reversed dermis flap. The pedicle of the flap remains intact. The mobile upper part of the flap is turned over the defect and the pedicle itself. A mesh graft covers both, the flap and the donor side. Two case reports will present the principles of the flap design and the clinical outcome of a patient with a defect over the lateral malleolar region and a patient with a defect over the Achilles tendon.
    Notes: Zusammenfassung Der deepithelialisierte “turn-over-flap” ist ein lokaler fasziokorialer Kutislappen, bei dem die deepithelialisierte Basis intakt bleibt. Die deepithelialisierte Basis oder der Lappenpedikel wird zusammen mit dem mobilen Teil des Lappens und dem zu überbrückenden Defekt abgedeckt. Eine Meshgraft-Deckung verschließt gleichzeitig dem rückwärtigen, nach außen gerichteten Lappen und den Hebedefekt. Anhand von 2 Kasuistiken wird das Prinzip des fasziokorialen “turn-over-flaps” erläutert. Einmal handelt es sich um einen Defekt über dem distalen Achillessehnenfach, zum anderen um eine Defektdeckung über dem lateralen Malleolarbereich.
