Body The chisel-shaped incisors are adapted for cutting and shearing food buy fucidin 10gm on line. The two pairs of cone-shaped canines (cuspids) are located at the anterior corners of the mouth; they are adapted for hold- Filiform ing and tearing. Incisors and canines are further characterized by papillae a single root on each tooth. The buccal surface of the premolars and molars is adjacent to the cheek. The labial surface Tongue of the incisors and canines is adjacent to the lip. The tongue is a mass of (milk) teeth begin to erupt at about 6 months of age (fig. All of the tongue muscles (those that insert upon the tongue) move the deciduous teeth normally erupt by the age of 2 1/2.

If you waste or allow any of this time to pass in the belief (indisputably true) that you don’t have to respond until the end of that 30 days order 10 gm fucidin fast delivery, or that your attorney can probably get an extension of time by which to respond (almost always true) fucidin 10 gm amex, you could lose valu- able opportunities to seize important advantages. The Importance of Time in the Discovery Process To illustrate the importance of time in litigation, consider the proce- dural device of discovery, the means by which parties are to find out from each other what evidence is known to that party or others in support or derogation of the lawsuit. One of these discovery mechanisms is the right to compel a party to appear and answer relevant questions under oath from your lawyer. The answers given to these questions often reveal facts that will determine whether the plaintiff has a viable claim against you or whether you have a defense against liability. Absent a showing to the court of “good cause,” a plain- tiff must normally wait 20 days after serving summons before noticing the defendant’s deposition; however, the defendant need not wait any period of time after being served to notice the plaintiff’s deposition. Hence, it is possible for a defendant to get the jump on the plaintiff and smoke out his or her case early regarding the extent of damage suffered and why the plaintiff believes the defendant is responsible for it. The longer you wait to take the plaintiff’s deposition, the greater the likelihood that “facts” will be revealed or become “known” to the plain- tiff that strengthen his or her case. For this reason, some defense lawyers prefer to wait to take the plaintiff’s deposition until later in the lawsuit, especially because you usually only get one opportunity to take the plaintiff’s deposition, unless there are unusual circumstances involved. However, if you have reason to believe the plaintiff has not put together a case by the time you are served, then it may be possible to get rid of the case early by showing that it is missing one or more elements critical to the liability equation. Time and Summary Judgment or Summary Adjudication Another procedural mechanism that can be combined with the prompt taking of the plaintiff’s deposition is a motion for summary judgment or partial summary adjudication. This motion is a way for the court to look behind the pleadings and determine if the opposing party’s pleadings lack evidentiary support that warrants limiting or terminating the lawsuit. A defendant who does not pay close attention to the passage of time could, through inadvertence, lose the right to invoke summary judgment and end up having to go to trial (perhaps unnecessarily). Chapter 2 / Litigation 31 Therefore, when served with summons, you should immediately notify your medical liability insurer and get a copy of the summons and complaint to the appropriate representative. While doing this, you should also request your insurer to inform you right away of the lawyer who will be defending you. Once you know the identity of your counsel, contact him or her and ask to meet and confer about your case, preferably in person; however, if that cannot be done right away, then make contact by telephone. WHY YOU SHOULD MEET WITH YOUR LAWYER RIGHT AWAY AND WHAT YOU SHOULD SEEK TO ACCOMPLISH The Importance of a Litigation Strategy and Discovery Plan To ensure that the meeting with your lawyer is as productive as possible, you should first read the complaint and try to discern from it what you are accused of having done or not done that supposedly makes you liable. If the complaint is what is known as a form com- plaint, this generally will be more difficult than if it is written by the plaintiff’s counsel and sets forth some specific facts. However, in read- ing the complaint, you will at least be able to learn the identity of the plaintiff and when the event that allegedly resulted in injury occurred, even if it is a general form. Check your own records to see what they reveal about the plaintiff and to help refresh your memory. Make cop- ies of these records so that you can review them without getting marks on your originals that could be misconstrued as attempts to alter the records. You will want to have reviewed whatever information you can quickly assemble before you meet with your attorney so that you can share all you recall about your role in treating the plaintiff. If there were others involved in the incident of treatment about which plaintiff com- plains, make some notes as to who they were, what role they played in that treatment, and how you know that they were involved or witnessed the treatment. What legal theories, other than negligence, is the plaintiff relying on? What are the necessary elements to those theories and how does your lawyer think the plaintiff will try to satisfy them? Are the theories asserted in the complaint’s various causes of action supported in law? Now, there are two things any good malpractice defense attorney will do to best represent a client: put together a discovery plan and a 32 Hiestand litigation strategy. The two go hand-in-hand, and although not all attorneys put them in writing, you will want a commitment from your attorney to do so for you. These are privileged documents, so your opponent will not be able to force you to disclose them. To be sure, both the initial discovery plan and litigation strategy will change as new information is learned and as there are rulings on motions filed by the parties that affect the course of the litigation.

The synaptic action of a NTmay also be increased by drugs that have an allosteric action on the receptor to increase its affinity or response to the endogenous NT generic 10gm fucidin otc, e order fucidin 10gm free shipping. Approaches (1)±(3) clearly depend on there being some residual neuronal function and NTrelease. Its value depends on all, or at least one stage, of the synthesis being sufficiently specific to the NTinvolved so that only its synthesis is affected. A good example would be choline acetyltransferase in the synthesis of ACh or glutamic acid decarboxylase in the synthesis of GABA. By contrast, inhibiting amino acid decarboxylase could reduce NA, DA and 5-HTsynthesis. It may be possible to reduce the neuronal uptake of a precursor if this requires a specific transport mechanism. Thus the synthesis of ACh can be reduced by blocking the uptake of precursor choline with hemicholinium. This is most likely to be achieved by stimulating inhibitory pre- synaptic autoreceptors (2a). Some drugs may reduce storage (2b) and hence release, although it is unlikely that this can be targeted at just one NT. As with agonists, these have the advantage that they can be designed to have a long half-life and act specifically on one type of receptor. Currently it is not possible to increase the rate of removal (uptake) or metabolism of a NT. RELATING NT MANIPULATION TO THE CAUSE OF THE DISORDER To what extent the above approaches can provide successful therapy will depend on both the cause of the disorder and the manner in which the NTis used in normal neuronal function. Thus the disorder could be due to: NEUROTRANSMITTER FUNCTION IN HUMANS 297 (1) An actual degeneration of a NTpathway or (2) No actual degeneration but a biochemical abnormality or some circuitry failure, leading to inadequate or excessive activity of the NT. The requirement in respect of NT function may be: (a) That it must be released physiologically from its nerve terminals by appropriate synaptic activity in order to produce the desired effect or (b) That it is sufficient merely to provide the NT at the synapse, without the need for it to be released physiologically. Clearly a disorder combining (1) with (a) would mean that little improvement could be expected by manipulating the lost NT, since the nerves are no longer there to release it physiologically. The main hope then would be to try to replenish the neurons with transplants (regeneration may be possible one day) and hope they become appro- priately innervated, or modify the action of some other NTwhich has become exaggerated (or reduced), as a result of the primary NTloss. By contrast it is easier to treat a disorder, whether characterised by neuronal degeneration ((1) above) or not (2), if it is sufficient just to provide NT(b), as appears to be the case in Parkinsonism. Of course, the effectiveness and specificity of any of the above manipulations will depend on how widely the NTis distributed and used and whether the malfunction applies only to one area or activity. Thus trying to increase (or decrease) the activity of a NTin only one area will be difficult if it has actions elsewhere which have not been affected by the disorder. The nervous system also has remarkable adaptive powers so the synaptic loss (or increase) of a NTis generally followed by a local compensating increase (decrease) in postsynaptic receptor number. This can be a useful response initially but it will be negated by the therapeutic provision of more (less) NT. Also a change in the activity of one NTcan lead to desirable compensating changes in the function of other NTs either working in conjunction with it or normally controlled by it. It must also be remembered that some NTs, like ACh, NA and 5-HT, have important peripheral as well as central roles and any attempt to modify them centrally will affect those peripheral effects as well. Thus if attempts made to increase the central action of a NT result in peripheral effects, these may be counteracted by using an appropriate antagonist that does not cross the blood±brain barrier. It is less easy to overcome peripheral side-effects caused by using a drug that antagonises the action of a NT, although in theory drugs that mimic or augment its action and do not cross the blood±brain barrier could be used. In fact this approach has proved valuable in treating the peripheral neuro- muscular disorder of myasthenia gravis which presents as a muscle weakness caused by insufficient cholinergic activity at skeletal neuromuscular junctions. The function of ACh can be increased and the symptoms alleviated, without central side-effects, by reducing the destruction of ACh by giving the anticholinesterase drug neostigmine, which does not cross the blood±brain barrier. Of course, nothing is perfect and anti- muscarinic drugs may be needed to overcome the accompanying increased peripheral parasympathomimetic effects of ACh. Despite all these problems there has been considerable progress in the treatment of disease states through NTmanipulation. Before the advent of levodopa therapy in Parkinsonism the treatment of neurological and psychiatric disorders had little 298 NEUROTRANSMITTERS, DRUGS AND BRAIN FUNCTION scientific basis but the initial and striking success with levodopa in Parkinsonism perhaps raised false expectations. In respect of drug therapy, Parkinsonism presented with a number of advantageous features that are unlikely to be repeated in other conditions.
