In receptors associated A with a specific G protein 10 mg provera with visa, a series of enzyme steps is initi- ated by binding of a transmitter to its receptor buy provera 5 mg on line, producing a second messenger that alters intracellular functions over a longer time than for direct ion channel opening. These EPSP membrane-bound enzymes and the second messengers they produce inside the target cells include adenylyl cy- clase, which produces cAMP; guanylyl cyclase, which pro- duces cGMP; and phospholipase C, which leads to the for- mation of two second messengers, diacylglycerol and inositol trisphosphate (see Chapter 1). When a transmitter binds to its receptor, membrane conductance changes occur, leading to depolarization or B hyperpolarization. An increase in mem- brane conductance that permits the efflux of K or the in- flux of Cl hyperpolarizes the membrane. In some cases, membrane hyperpolarization can occur when a decrease in membrane conductance reduces the influx of Na. Each of IPSP these effects results from specific alterations in ion channel function, and there are many different ligand-gated and voltage-gated channels.

Axon The responses of two neurons to a brief application of depolariz- ing current (I) are shown here. Each neuron depolarizes to the same degree, but the time for return to the baseline membrane po- tential differs for each. Neuron 2 takes longer to return to baseline than neuron 1 because its time constant is longer ( m2 m1). Con- EPSP 1 EPSP 2 sequently, longer periods of depolarization increase the likelihood of summating two postsynaptic potentials.
Although there are no data to demonstrate that participation in an external proficiency testing program lessens a laboratory’s liability provera 2.5 mg free shipping, participation is encouraged for its educational and QA value cheap provera 2.5mg on line. Failure to recognize that a Pap smear is “unsatisfactory for evaluation. Failure to use the current Bethesda System terminology (8), which is now part of the cytology standard of practice. Preventative Measures The followiwng list contains some preventative measures that can be taken: 1. Pathologists must make certain that their laboratories adhere to current CLIA 88 standards, because they have become part of the legal definition of the standard of care. Therefore, in the absence of a sub- poena, do not send cytology slides to an attorney for review. Instead, require the plaintiff’s “experts” to come to your lab to review the slides under your direct supervision. Evaluate and report the adequacy of each specimen, utilizing the Bethesda System specimen adequacy criteria. Provide recommendations for follow-up of Pap smears with epithelial cell abnormalities or specimen adequacy limitations, especially for nongynecologists. The 2001 Consensus Guidelines for Cervical Cyto- logical Abnormalities sponsored by the American Sociesty for Colpos- copy and Cervical Pathology (ASCCP) are recommended (13). Use outside expert consultation for problem Pap smears, when appro- priate. Restrict discussions about potential claims to individuals within your practice group. Limit the number of people within your group who review a potential problem Pap smear, because anyone who reviews it may be subsequently deposed. Notify your insurance company early if you suspect that a claim may be filed. Chapter 13 / Pap Smear Litigation 177 Long-Term Solutions and Questions to Explore Long-term solutions and questions that should be explored include the following: 1. We need a reasonable practitioner standard or a process standard, not an outcome standard; following the proce- dures proven to minimize the false-negative rate (complying with CLIA 88 regulations is a minimum standard) should become the stan- dard of care rather than the current unattainable standard of having a zero false-negative rate. Develop criteria that define an expert witness and create a national registry of certified expert witnesses.
