ASSESSING QUALITY OF THE PSA SCREENING DECISION: INTEGRATING SHARED DECISION MAKING INTO PRIMARY CARE. C.D. Brackett1; N. Cochran2; M. Coutermarsh1; S. Kearing3; C. Clay1; B. Brooks1. 1Dartmouth Hitchcock Medical Center, Lebanon, NH; 2White River Junction VAH, White River Junction, VT; 3 Dartmouth Medical School, Hanover, NH. Tracking ID # 173617 ; BACKGROUND: Prostate cancer screening with the prostate-specific antigen PSA ; blood test is controversial, and the decision to screen should be guided by patient preference. The quality of this decision reflects the patient s knowledge and understanding of the relevant information and concordance of the decision with the patient s values. Engaging patients in decision making during office visits is challenging, especially in primary care. The goal of this study was two-fold: 1 ; assess feasibility of integrating a PSA screening decision aid DA ; into the routine process of primary care practice, and 2 ; assess impact of the DA on patient decision making. METHODS: We systematically distributed a PSA screening video DA to eligible men age 5075 ; at Dartmouth Hitchcock Medical Center DHMC, n 242 ; and White River Junction VA Hospital VAH, n 215 ; . Patients were asked to: 1 ; complete a pre-DA questionnaire, 2 ; watch the DA BPSA Screening: Is It Right for You? , and 3 ; complete a post-DA questionnaire. Measurements included pre post screening intention, values influencing the decision Likert: 110 importance ; , multiple choice knowledge questions, preference for decision making role, and DA acceptability. Analysis focused on within sample and across site distributions of treatment choice, knowledge and values scores. RESULTS: After watching the DA, a substantial number of patients changed their intention for PSA screening DHMC: 24%, VAH: 31% ; . Patients at both sites were less likely to be unsure about their decision and more likely to opt out of PSA screening after viewing the DA p .01 ; . Knowledge scores after the DA were high 93% DHMC, 87% VAH ; , indicating patients understood key facts associated with their decision. Patients value of BDesire to know if you have cancer was strongly associated with patients leaning toward PSA screening OR 1.8, 95% CI 1.42.9 while patients who felt it was important to BAvoid worry from false alarm were more likely to choose no PSA screening OR 0.7, 95% CI 0.60.9 ; . Patients had a clear preference for taking the lead role in decision making 63%, 71% ; or sharing the decision with their clinician 35%, 29% ; . Patients found the DA helpful in making their decision 87, 85% ; and would recommend it to others 94, 96% ; . CONCLUSIONS: The systematic distribution of a PSA screening decision aid to patients in primary care practice is feasible. Patients prefer an active role in decision making regarding PSA screening, and the DA helped them make this decision. After watching the DA, patients demonstrated an understanding of the key facts and concordance between their values and their choice, indicative of quality decision making. Patients found the DA acceptable and would recommend it to others facing the same decision. This process is likely to be appropriate for other preference-sensitive decisions in primary care.

Ematologic side effects of neuroleptic and anticholinergic drugs are rare but can be dangerous. There are several reports associating agranulocytosis with the use of antipsychotics.16 There have been only a few case reports of the appearance of thrombocytopenia during the use of antipsychotics.710 To our knowledge there has been no published case report of thrombocytopenia associated with the use of olanzapine or benztropine mesylate. We report a case in which there was a significant decrease of platelets associated with the use of olanzapine and subsequently with the use of benztropine mesylate. We also postulate a mechanism as to how both of these drugs could have caused thrombocytopenia in the same patient.
CPT-11 SN-38 lactone to carboxylate, as shown in the present study. It is generally accepted that the -hydroxy lactone ring is an absolute requirement for CPT-derived molecules to have in vitro and in vivo activities 49 51 ; . However, although circumventing the opening of the lactone ring is one of the strategies proposed in order to optimize the antitumor activity of this drug 52 ; , the lactone ring is unstable at physiological pH and above and can open to the much less active carboxylate form. Therefore, it is our hypothesis that the reduced incidence and severity of CPT-11-induced diarrhea is attributable, at least in part, to the opening of the lactone ring in the intestinal lumen. The rationale for this theory is based on our findings in both HT-29 cells and in enterocytes isolated from hamster small and large intestine 30 ; . Results of these studies show that the initial uptake rate of the lactone form of SN-38 by HT-29 cells was significantly greater than that of its carboxylate counterpart Fig. 1 ; . Furthermore, in contrast to the lactone form, for which uptake remained unchanged, the transport of SN-38 carboxylate was carrier mediated and could specifically and significantly be inhibited by the addition of dinitrophenol 30 ; . Finally, the initial uptake rate presents a good correlation with the cytotoxicity of SN-38 in HT-29 cells see "Results" and Ref. 30 ; . This difference in the cytotoxicity of CPT-11 and SN-38 in HT-29 cells can probably be attributed to the respective differential rate of conversion between the lactone and carboxylate form of these agents. Indeed, Akimoto et al. 53 ; have reported that the constant of hydrolysis of SN-38 50% conversion from lactone to carboxylate ; was 13.5 h and 33 min at pH 6 and pH 7.4, respectively. Furthermore, Rivory et al. 39 ; have reported that conversion of CPT-11 lactone to carboxylate in vivo was rapid, whereas SN-38 was present predominantly as the lactone form at all times. The HPLC determination in the cell culture medium indicated that even after 2-h incubation at pH 7.4, SN-38 prepared at pH 6.2 and 7.6 remained 70 and 25% as lactone, respectively. This limited conversion of the lactone to the carboxylate form was further supported by the fact that similar toxicity was observed independently of the pH of the incubation medium during the 2-h incubation period of the cells with SN-38 lactone. As reported in the present study, the lactone form of SN-38 was more potent to induce both S and G2-M phase cell cycle arrest and apoptosis than its carboxylate counterpart. These results are consistent with what has been reported previously with camptothecin 33, 34 ; . The lack of G1 arrest is probably attributable to the p53 mutation in.

Benztropine dosage forms
Keeping with those of McIntyre et al. 8 ; , who showed that this collection is more sensitive than early morning serum cortisol. They also showed that high dose 2000 g day ; , but not low dose 800 g day ; , inhaled beclomethasone dipropionate produced significant suppression of both overnight and early morning corrected urinary cortisol creatinine, as was the case in our study with low and high dose TAA and FN. Thus, for everyday routine clinical out-patient assessment, compliance is likely to be worse with a 24-h urine collection than with an overnight or early morning urine collection. Further population-based studies appear to be indicated to investigate this issue and betaseron.
Perilously, and were greedy to follow their statutes, yee their lust was in all things to be like them, which afore were their enemies and destroyers. How be it to wickedly against the law of God, shall not escape unpunished: but of this we shall speak here after. What time as the Olympiades sports were played at Tyrus the king himself being present ; this ungracious Jason sent * wicked men bearing from them of Jerusalem which were now called Antiochians ; three hundred drachmas of silver for an offering to Hercules. These had they that carried them, desired under such a fashion, as though they should not have been offered, but bestowed to other uses. Nevertheless he that sent them, sent them to the intent that they should be offered unto Hercules. But because of those that were present, they were given as to the making of ships. And Apollonius the son of Nesteus was sent into Egypt, because of the noble men of king Ptolomy Philometor. Now when Antiochus perceived that he was put out from meddling in the realm, he sought his own profit, departed from thence, came to Joppa, and then to Jerusalem: where he was honorably received of Jason and the city, and was brought in with torch light and with great praise: and so he turned his host unto Phenices. After three years Jason sent Menelaus, the aforesaid Simons brother, to bear the money unto the king, and to bring him answer of other necessary matters. But he when he was praised of the king for magnifying of his power ; turned the priesthood unto himself, laying up three hundred talents of silver for Jason. So when he had gotten the commandments from the king, he came having nothing that becometh a priest, but bearing the stomach of a cruel tyrant, and the wrath of a wild brute beast. Then Jason which had deceived his own.
As well, we found no consistent correlation between effectiveness against FDM and chemical properties thought to be predictive of muscarinic antagonism.33 Thus, the question remains whether rescue by atropine, pirenzepine, himbacine, and oxyphenonium could be mediated by a nonmuscarinic mechanism. Evidence against a specific action of these drugs can be inferred from the study by Lind et al.32 cited earlier. The action of muscarinic antagonists in the absence of any known source of acetylcholine in scleral cell culture may argue for a non-mAChRmediated action. The ability of atropine and pirenzepine to prevent FDM even when cholinergic cells and receptors are absent from the retina could be explained by action through some noncholinergic, nonmuscarinic receptor or cellular signal mechanism, even one located in the retina, that is necessary for control of eye growth. The phenomenon of binding and action of drugs from one class on receptors of another class has been observed in previous studies. For example, many opiate agonists and antagonists are known to bind to and block N-methyl-D-aspartate NMDA ; receptors.34, 35 As well, one of the partially effective muscarinic antagonists, benztropine, is known to block dopamine transporters36 and to increase dopamine efflux from neurons of the substantia nigra.37 Benztropine did not elicit full rescue in the present study, however. Still, it is conceivable that oxyphenonium, pirenzepine, and atropine could exert some benztropine-like activity through the dopaminergic system, although atropine is not an effective dopamine reuptake blocker.37 Some of these muscarinic compounds may also be acting through nicotinic receptors in the eye, as has occurred in studies of atropine on rat nAChRs.38 Stone et al.39 reported that four nicotinic antagonists have myopia- and growth-preventing effects in form-deprived chicks and that nAChRs may therefore be involved in eye growth. In view of the evidence cited herein, it is possible that some receptor types other than mAChRs mediate the FDM rescue activity of atropine, pirenzepine, himbacine, and oxyphenonium. If the binding affinities of muscarinic antagonists for nonmuscarinic receptors were significantly lower than for mAChRs, then higher concentrations of the drugs would be required to stimulate or inhibit the signal mechanism, even if the target receptors were located in the retina. Therefore, this hypothesis is consistent with our observations. In summary, given the evidence from this study and from Fischer et al., 13 it remains a strong possibility that cholinergic receptors in the retina are not the route by which atropine and other muscarinic antagonists prevent FDM. Whether the mechanism is through retinal nonmuscarinic mechanisms, or muscarinic receptors in extraretinal tissues, is still not clear. However, if a muscarinic mechanism outside the retina were the functional route, then it would be expected that several of the antagonists tested-- especially those with relatively nonselective binding profiles, such as scopolamine, dexetimide, QNB and 4-DAMP--would have elicited a full rescue effect. Because these drugs were not fully effective and effectiveness was not strongly correlated with structural indicators of specific antimuscarinic activity, we suggest that the few antagonists that fully prevent FDM probably do so through nonmuscarinic mechanisms and betaxolol.

The influence of cycloheximide, a potent inhibitor of protein synthesis, and actinomycin D, an inhibitor of RNA synthase, were also studied to determine the site of action of dexamethasone. Cycloheximide by itself slightly increased the specific binding of AVP on WRK1 cells grown in a culture medium deprived of endogenous dexamethasone. It completely prevented the increase of AVP binding sites induced by 0.1 dexamethasone Table 5 ; . Actinomycin D treatment by itself reduced the specific binding of AVP by -40%. Moreover, as already observed for cycloheximide, it completely suppressed the positive influence of dexamethasone on AVP binding sites Table 5.

Abrupt Wlthdraw&: In general. phenolhiazines do nOl produce psychic dependence. However. gastritis, nausea and vomiting, dizziness, and tremulousness have been reported following abrupt cessation of high dose therapy; reports suggest that these symptoms can be reduced if concomitant antiparkinsonian agents are continued for several weeks after the phenolhiazine is withdrawn. ADVERSE REACTIONS: Central Nervous System-Extrapyramidal symptoms are most frequently reported. Most often these symptoms are reversible, but they may be persistent. Their include pseudoparkinsonism, dyslonia. dyskinesia, akathisia, oculogyric crises, opisthotonos, hyperreflexia. The incidence and severity of such reactions will depend more on individual patient sensitivity, but dosage level and patient age are also determinants. As these reactions may be alarming. the patient should be forewarned and reassured. These reactions can usually be controlled by administration of an anti-parkinsonian drug such as benztropine mesylate and by subsequent reduction in dosage Persistent Tardive Dyskines, a As with all antipsychotic agents. persistent and sometimes irreversible tardive dyskinesia may appear in some patients on long-term therapy or may occur after discontinuation 01 drug The risk seems greater in elderly patients, especially females. on high dosages. The syndrome is characterized by rhythmical involuntary movements of tongue, face, mouth, or jaw e 9 , protrusion of tongue. puffing of cheeks, puckering of mouth, chewing movements ; and may be accompanied by involuntary movements of extremities. There is no known effective therapy for tardive dyskinesia; usually the symptoms are not alleviated by antiparkinsonism agents. If the symptoms appear. discontinuation of all antipsychotic agents is suggested The syndrome may be masked iftreatment is reinstituted, or drug dosage increased, or a diflerent antipsychotuc agent used. Reports arethatfine vermicular movements of the tongue may bean early sign ofthe syndrome which may not develop if medication is stopped at that time. Phenothiazine derivatives have been known to cause restlessness, excitement, or bizarre dreams. reactivation or aggravation of psychotic processes may be encountered. If drowsiness or lethargy occur. the dosage may need to be reduced Dosages. far in excess of the recommended amounts, may induce a catatonic-like state. Autonom, c Nervous System-Hypertension and fluctuations in blood pressure have been reported Although hypotension is rarely a problem, patients with pheochromocytoma. cerebral vascular or renal insufficiency or severe cardiac reserve deficiency such as mitral insufficiency appear to be particularly prone to this reaction and should be observed carefully. Supportive measures including intravenous vasopressor drugs should be instituted immediately should severe hypotension occur; Levarterenol Bitartrate Injection isthe most swtable drug; epinephrine should not be used since phenolhiazine derivatives have been found to reverse its action. Nausea. loss of appetite, salivation, polyuria. perspiration, dry mouth, headache and constipalion may occur Reducing or temporarily discontinuing the dosage will usually control these effects. Blurred vision, glaucoma. bladder paralysis. fecal impaction, paralytic ileus. tachycardia. or nasal congestion have occurred in some patients on phenothiazine derivatives. Metabolic and Endocrine-Weight change. peripheral edema, abnormal lactation, gynecomastia. menstrual irregularities. false results on pregnancy tests, impotency in men and increased libido in women have occurred in some patients on phenothiazine therapy. Allergic Reactions-Itching. erythema, urticaria, seborrhea, photosensitivity. eczema and exfoliative dermatitis have been reported with phenothiazines The possibiiity of anaphylactoid reactions should be borne in mind Hematologic-Blood dyscrasias including leukopenia, agranulocytosis. thrombocytopenic or nonthrombocytopenic purpura. eosinophilia. and pancytopenia have been observed with phenothiazines If soreness of the mouth, gums or throat or any symptoms of upper respiratory infection occur and confirmatory leukocyte count indicates cellular depression, therapy should be discontinued and other appropriate measures instituted immediately. Hepatic-Liver damage manifested by cholestatic laundice, particularly during the first months of therapy. may occur; treatment should be discontinued. A cephalin flocculation increase. sometimes accompanied by alterations in other liver functiontests. has been reported in patients who have had no clinical evidence of liver damage. Others-Sudden deaths have been reported in hospitalized patients on phenothiazines. Previous brain damage or seizures may be predisposing factors. High doses should be avoided in known seizure patients Shortly before death, several patients showed flare-ups of psychotic behavior patterns. Autopsy findings have usually revealed acute fulminating pneumonia or pneumOnitis. aspiration of gastric contents. or intramyocardial lesions. Although not a general feature of fluphenazine, potentiation of central nervous system depressants such as opiates.
