Endoskopische Verfahren

Einleitung: Vor der Ära der laparoskopischen Cholezystektomie und der endoskopischen Steinextraktion waren die nichtchirurgischen Therapien bei der Behandlung von symptomatischen Gallensteinen, wie die Kontaktlitholyse mit Äther, eine valable Alternative. Bei inoperablen Patienten mit akuter Cholezystolithiasis und endoskopisch nicht zugänglichen Gallensteinen kann auch heute noch erfolgreich darauf zurückgegriffen werden. Fallbeispiel: Bei einem 85-jährigen Patienten in schlechtem Allgemeinzustand und einer Cholangiosepsis nach endoskopischer Papillotomie und partieller Steinextraktion wurde bei drohender Gallenblasenperforation infolge progredientem Hydrops ultraschallkontrolliert ein perkutaner pigtail Katheter eingelegt. Nach mehrmaliger Instillation von Methyltertbutyläther (MTBE) über den liegenden Drain in Gallenblase und Gallenwege gelang es, die Restkonkremente aufzulösen. Der Patient ist drei Monate nach Eingriff beschwerdefrei. Diskussion: Symptomatische Gallensteine, bei denen endoskopische Verfahren nicht zum Erfolg führen, sind selten. Kommt ein drohender Gallenblasenhydrops hinzu, ist die perkutane Drainage der Gallenblase und anschliessende Kontaktlitholyse mit MTBE eine patientenschonende, effektive Therapieform. Die Erfolgsrate liegt bei nicht verkalkten Gallensteinen bei 70 bis 95%, je nach Grösse und Anzahl der Konkremente. Die Methode zeichnet sich zudem durch eine geringe Morbidität aus. Schlussfolgerungen: Bei inoperablen Patienten mit schwerer Cholezystitis und Gallenblasenhydrops ist die perkutane Drainage der Gallenblase und eine Kontaktlithothripsie durch MTBE eine patientenschonende, sichere und kostengünstige Therapie.

F Ring

ABSTRACTSaturn's broad E ring, the narrow G ring and the structured and apparently time variable F ring(s), contain many micron and sub-micron sized particles, which make up the “visible” component. These rings (or ring systems) are in direct contact with magnetospheric plasma. Fluctuations in the plasma density and/or mean energy, due to magnetospheric and solar wind processes, may induce stochastic charge variations on the dust particles, which in turn lead to an orbit perturbation and spatial diffusion. It is suggested that the extent of the E ring and the braided, kinky structure of certain portions of the F rings as well as possible time variations are a result of plasma induced electromagnetic perturbations and drag forces. The G ring, in this scenario, requires some form of shepherding and should be akin to the F ring in structure. Sputtering of micron-sized dust particles in the E ring by magnetospheric ions yields lifetimes of 102to 104years. This effect as well as the plasma induced transport processes require an active source for the E ring, probably Enceladus.

Agricultural Plants

The Worker Protection Standard (WPS) is a Federal regulation designed to protect agricultural workers (people involved in the production of agricultural plants) and pesticide handlers (people mixing, loading, or applying pesticides or doing other tasks involving direct contact with pesticides).There are certain exemptions in the WPS rule that have been revised pertaining to agricultural establishment owners and their immediate family members. This fact sheet explains these new provisions.

General Guidance

The Worker Protection Standard (WPS) is a Federal regulation designed to protect agricultural workers (people involved in the production of agricultural plants) and pesticide handlers (people mixing, loading, or applying pesticides or doing other tasks involving direct contact with pesticides). It has been in full implementation since 1995. This document provides general guidance to help you comply with the requirements of the Federal Worker Protection Standard (WPS) for agricultural pesticides, 40 CFR part 170, as amended in 2015. This document addresses specific information that agricultural establishments must display at a central location for their employees.
