Abstract:  The advent of sentinel lymph node (SLN) biopsy for breast cancer has had a considerable impact on clinical oncology. The SLN procedure has been widely adopted, but major clinical issues remain unresolved pending the outcome of randomized trials. Pathologic handling of SLNs is less controversial; however, significant pitfalls in their handling have been reported. Herein we report two additional uncommon situations that demonstrate the need for the utmost vigilance in both the macroscopic examination (i.e., trimming of “positive” nodal tissue) and microscopic examination (i.e., presence of nevus cell aggregates mimicking metastatic carcinoma) of SLN specimens.

A double-blind, randomised, placebo-controlled study was undertaken to determine whether topical application of a nonsteroidal anti-inflammatory gel to skin overlying peripheral vein cannula sites has a role in reducing the incidence or delaying the onset of peripheral vein thrombophlebitis. Fifty normal subjects had intravenous cannulae placed in right and left arms. Subjects were randomised to receive twice daily application of either active nonsteroidal anti-inflammatory gel or placebo gel to each cannula site. Cannula sites were observed and signs and symptoms of inflammation recorded up to 108 h. If any site had signs extending beyond 2 cm then the cannula was removed. Cannula sites that had ‘active’ gel applied had half the incidence of marked signs at 108 h (44% vs 22%, p 〈 0.05). These results suggest that local application of topical nonsteroidal anti-inflammatory gel to cannula sites may have a significant role to play in the prevention of peripheral vein thrombophlebitis.

Abstract A 14-year-old black female was found to have massive lymphadenopathy and osteomyelitis of the sternum in association with a parasternal mass. Diagnostic studies revealed tuberculosis as the etiology of this patient's skeletal and mediastinal disease. The differential diagnosis of chest wall lesions accompanied by mediastinal disease is discussed.

Abstract The fate of total lipids, proteins and carbohydrates in the trachea, lungs, and heart of the common ground squirrel,Funambulus pennanti, have been determined after separate exposure to three principal air pollutants, carbon monoxide (CO), sulphur dioxide (SO2), and nitrogen dioxide (NO2). Exposure to all of these gases produced edematous conditions; however, the moisture content of heart muscle was reduced. Carbon monoxide (CO) and NO2 are more toxic to pulmonary lipids than SO2. The lipid content of the heart decreased, least effects noted with SO2 treatment. Mechanical properties of the lungs were changed by alteration of the lung lipids causing changes in the surface tension. Changes in protein content were caused by altered membrane permeability. Comparative data on the carbohydrates indicated adverse effects by the pollutants.

Summary An attempt has been made to study the protective effect of a new chelating agent named p-amino salicylic acid oxine azo dye complex and metallic zinc on the Ccl4 induced hepatic injury in squirrels. This is probably the first multidisciplinary approaching (histological, histochemical and biochemical), report, employing this chelating agent and zinc together in the cure of a hepatic tissue. Apart from a pathological support, biochemical estimation of two enzymes noticed: Viz glucose-6-phosphatase dehydrogenase andβ-glucuronidase were treated as enzymatic denominators in liver cure. It further claims the suitability of the drug for clinical use. However, a detailed mechanism of action of this chelating agent remains practically unknown. It is hypothesized, that chelation of zinc facilitates the peneteration of a drug complex in the hepatic cells. Further zinc serves the purpose of drug transporter. The chelating agent masks the toxic substances (metabolites of Ccl4), which are eventually excreted, but still bound to it. The regeneration progresses speedily, after the biomembranes are stabilized.

Abstract The protective effects of glutathione-dependent enzymes have been studied against cadmium toxicity in the liver and kidney of two fresh water fishesChanna punctatus andClarias batrachus. Specie's differences in the activity of tissue enzymes have also been studied. Cadmium treatment induced lipid peroxidation in the liver and kidney of both species, the kidney being the more susceptible. Enzymological observations revealed thatChanna punctatus is better equipped with conjugating enzymes thanClarias batrachus. Fish having higher activities of these enzymes are thus expected to withstand oxidative stress more effectively.

Abstract The Telecommunications Information Networking Architecture Consortium (TINA-C) was formed 5 years ago to develop an architecture to address the radical business and technological changes then envisaged in the future telecommunications world. Central to the proposed solution is an infrastructure known as the TINA distributed processing environment (DPE). The TINA service architecture, which defines a set of concepts and rules for the management of a wide range of services, is of particular interest here. This paper outlines the current status and output of the TINA Consortium and goes on to describe a collaborative implementation project which uses many of the TINA concepts and specifications to build a pan-European service platform. An important vision within TINA is that of open interfaces and interoperability in a heterogeneous environment. The extent to which this goal has been achieved is discussed in the light of experience.

Abstract The ability to carry stream information over a range of network types in a managed way will become an essential requirement for telecommunications network operators as future services evolve to include the transmission of audio/video and bulk data streams. This paper details the architecture of a working pan-European demonstrator offering multimedia services through the integration of stream control, as specified in the Object Management Group's (OMG's) control and management of audio/video streams, with a TINA-compliant service management environment. This CORBA-based demonstrator, known as the EURESCOM services platform (ESP), has been developed by six European telecommunications companies within EURESCOM project P715. Various modelling concepts, as defined by TINA, ODP and OMG, have been used and verified in a first prototype implementation, with connectivity provided by commercially available multimedia technology such as H.320/323 products. This EURESCOM services platform prototype is one of the first demonstrators world-wide to implement OMG's control and management of audio/video streams specification.

Abstract Today's distributed systems consist of many different components, making the efficient management of such systems an extremely difficult task. Group communication should provide a potential solution to make the management process more flexible. It is possible to build a group communication system based on traditional distributed technology such as CORBA (Common Object Request Broker Architecture), but efficiency is poor due to lack of support for multicast and the overhead of building groups in current commercially available products. Multicast is a key part of a future group communication architecture and although reliability is not yet supported there are workarounds which provide a solution. This paper discusses the design and implementation of reliable IP multicast protocols for group communication. One important aspect of this work is the modularisation of the protocol blocks, and the design of a modular protocol, which can be used in conjunction with other similar protocol blocks to build a communication stack for group communications, is described in detail.
