Compatibility of impressions and die stone material

The compatibility of four impression materials with 11 different die stones was tested. All the combinations tested performed within the 20 microns ADA standard.     

Orthotic devices for serratus anterior palsy: some biomechanical considerations.

The pathomechanics of serratus anterior palsy are reviewed to provide a physiological basis for designing an effective brace. The problems involved in the practical application of the brace and the effectiveness of the brace in controlling the biomechanical dysfunctions are discussed. Two modifications of the basic brace and their effects on the patients' shoulder functions are presented. The main benefit of scapular bracing is control of scapular winging, while loss of active scapular rotation and medial scapular displacement cannot be effectively corrected.     

Pitfalls in the diagnosis of intussusception

Unusual sonographic behavior of intussusception is demonstrated in 4 cases. The results of 54 well-documented cases have shown two possible deviations from the normal sonographic pattern of an intussusception. The first was a highly reflective target sign, and the second a loss of regular sonographic structure in a tumor-like mass.     

170. Bougierung und Intubierung maligner Oesophagusstenosen

Zusammenfassung Von 46 palliativ durchgeführten Tubusimplantationen wurde in 22 Fällen der endoskopische und in 24 Fällen der operative Weg mittels Gastrotomie gewählt. Es werden die unterschiedlichen Implantationsverfahren hinsichtlich ihrer Komplikationen (Letalität, Perforationen, Blutungen, Tubusdislokationen und -occlusionen sowie pulmonale Folgen), der Krankenhausaufenthaltsdauer, der Überlebensrate und des Kostenfaktors verglichen. Dabei erweist sich das endoskopische Implantationsverfahren gegenüber dem operativen Vorgehen in bezug auf die Krankenhausaufenthaltsdauer (7 Tage im Vergleich zu 26 Tagen), dementsprechend auf die Krankenhauskosten sowie die Klinikletalität (9,5% im Vergleich zu 28%) und auf die postoperative Morbidität als überlegen.     

Intraabdominal abscesses — Percutaneous catheter drainage versus operative treatment

Summary From 65 patients with 73 abscesses 38 were treated by operation and 27 by PCD. The mean duration of drainage was 6.8 days (OP) and 7.4 days (PCD) respectively. In the surgical group 2 patients needed reintervention and 1 died due to sepsis. In the PCD group 1 patient had to be operated on because of insufficient drainage and 1 died after perforation of the colon.With modern techniques of imaging (Ultrasound, CT) PCD is a useful tool in the therapeutic regimen of intraabdominal abscesses. PCD has to be considered as definitive treatment or preparation for surgical eradication. Above all indication to PCD depends on localization and cause of the abscess.Abbrevations PCD Percutaneous Catheter Drainage - OP Operation - CT Computed Tomography     

Cholera control on Guam, 2000

During April, 2000, the island of Pohnpei began experiencing an outbreak of cholera and during June and July of the same year four cases of cholera representing 3 separate introduction events were identified on Guam. Two of these events were associated with eating reef fish imported from Pohnpei. Following the imposition of a narrowly-focused ban on the importation of inshore seafood and processed food products from Pohnpei, no additional local or imported cases of cholera were detected on Guam.
