That discovery plan should set forth the facts essential to prove the elements of any theory of liability asserted and of any defense you will assert buy discount symmetrel 100 mg on line. Your attorney should seek a stipulation with opposing counsel as to material facts that you believe will not be disputed and put that stipulation in writing. The discovery plan should indicate the discovery device(s) that will be used to prove or disprove the existence of each element of all claims and defenses and the source of proof for each fact pertinent to those elements. The extent of claimed damages is something that you will want to nail the plaintiff down on. Do the local court rules limit the number of experts and, if so, does this hurt your defense? What experts has Chapter 2 / Litigation 33 plaintiff’s counsel used in the past for medical malpractice cases? In doing this, your sense of how the rules and players interact and can affect the outcome of the litigation game will make you a more valuable contributor in preparing to win. Chapter 3 / Risk Reduction 35 3 Risk Reduction From a Plaintiff Attorney’s Perspective David Wm. Horan, MD, JD SUMMARY This chapter looks at malpractice litigation from the unique view- point of the plaintiff attorney. What aspects of the doctor– patient relationship most affect the likelihood of litigation? What aspects of a physician’s care, demeanor, and communication skills make him or her more or less formidable as a defendant? The chapter also discusses the physician’s role in educating his or her own attorney and the preparation needed for a successful defense.

But it now seems likely that the actual block of sodium channels is its primary action (see later) buy 100 mg symmetrel amex. The epileptic discharges induced in hippocampal slices by tetanic stimulation has been shown to be accompanied by reduced GABA-mediated IPSPs (Stelzer, Slater and Bruggencate 1987). Since AP7 not only reduced the discharges but also restored the response to GABA some linkage between NMDA and GABAA receptors seems probable. In fact the interaction between glutamate and GABA probably means that both of them and possibly their different receptors may need to be manipulated appro- priately to control convulsive activity. This has been shown in fact experimentally when bicuculline was infused intravenously for short periods in the rat to give a burst of epileptic-like spiking in the EEG. Superfusion of the cortex using the cup technique with the glutamate AMPA antagonist CNQX or the GABAB agonist baclofen reduced the actual number (initiation) of spikes but not their amplitude, while NMDA antagonists (AP7) and the GABAA agonist muscimal reduced the size (development and spread of excitation) and not the number of spikes (Zia-Gharib and Webster 1991). Clearly more than one aspect of amino acid function may need to be controlled. Other NTs have been implicated in the aetiology of epilepsy but direct evidence is lacking. Many studies have also shown that cortical ACh release increases in proportion to EEG activity during the administration of a wide range of convulsants. Nevertheless while cholinergic-induced seizures can be suppressed by antimuscarinic drugs they have no effect against any epilepsy in humans and ACh release presumably reflects rather than directly causes cortical activity. MONOAMINES The widespread and diverging nature of ascending monoamine pathways to the cortex suggest that NA and 5-HTare more likely to have a secondary modifying rather than a primary effect on the initiation of epileptic activity. In reality this is the case and their secondary role is even a minor one. Generally a reduction in monoamine function facilitates experimentally induced seizures (see Meldrum 1989) while increasing it reduces seizure susceptibility.

The Technical Considerations Intravenous delivery The usual dose of gadolinium for pediatric muscu- loskeletal applications is 0. Intravenous access is achieved prior to sedation or im- mediately before obtaining postcontrast sequences in non-sedated children. The use of Emla cream is very effective for anesthetizing the injection site. In a dy- namic gadolinium-enhanced MR study is to be carried out, contrast-filled extension tubing allows scanning before, during and after bolus injection without inter- ruption. Pulse sequences The imaging protocol should always include a precon- trast T1-weighted sequence followed by a series of Fig. Sebag quickly growing regions of the body; thus, the number and distribution of these canals change with maturation [5, 10, 11]. In the physis and the acrophysis (growth cartilage of the ossification center), enhancement is very intense.
