Abstract
Despite advances in the storage and retrieval of information within health care systems, health researchers conducting surveys for evaluations still face technical barriers that may lead to sampling bias. The authors describe their experience in administering a Web-based, international survey to English-speaking countries. Identifying the sample was a multistage effort involving (a) searching for published e-mail addresses, (b) conducting Web searches for publicly funded agencies, and (c) performing literature searches, personal contacts, and extensive Internet searches for individuals. After pretesting, the survey was converted into an electronic format accessible by multiple Web browsers. Sampling bias arose from (a) system incompatibility, which did not allow potential respondents to open the survey, (b) varying institutional gate-keeping policies that "recognized" the unsolicited survey as spam, (c) culturally unique program terminology, which confused some respondents, and (d) incomplete sampling frames. Solutions are offered to the first three problems, and the authors note that sampling bias remains a crucial problem.

Abstract
Mental health diversion is a process where alternatives to criminal sanctions are made available to persons with mental illness (PMI) who have come into contact with the law. One form of mental health diversion is pre-arrest, in which the police use their discretion in laying charges. Concomitant with the growth of pre-arrest diversion programs is a growing body of research devoted to the phenomenon. The purpose of this paper is to review the existing literature of pre-arrest diversion, and to report the results of an international survey of pre-arrest diversion programs we conducted to identify evidence-based practices. On the basis of our review and survey, we note that successful pre-trial programs appear to integrate relevant mental health, substance abuse and criminal justice agencies by having regular meetings between key personnel from the various agencies. Often, a liaison person with a mandate to effect strong leadership plays a key role in the coordination of various agencies. Streamlining services through the creation of an emergency drop-off center with a no-refusal policy for police cases is seen as crucial. While there is some indication that mentally ill offenders benefit from their participation in this form of diversion, the evaluative literature has not yet achieved the "critical mass" necessary to create generalizable, evidence-based knowledge. The absence of generally agreed-upon outcomes could lead to the inequitable application of basic principles of diversion. We suggest that indicators, benchmarks, and outcomes must be agreed upon if a comprehensive understanding of pre-arrest programs is to emerge.

Abstract
On 4 October 2000, Bill 119 (or the Red Tape Reduction Act, 2000) was introduced and received first reading in Ontario's provincial legislature. Like many of the other similarly titled bills the Harris government has introduced, Bill 119 proposes to change a long list of existing statutes in an effort to make Ontario more business friendly. Schedule G of Bill 119 sets out a mechanism whereby a viatical industry in Ontario would be made legal if a licensing scheme is first put in place by the Ministry of Finance.

Abstract
PURPOSE Our aim was to evaluate the efficacy, toxicity, and pharmacokinetic behavior of single-agent paclitaxel given weekly to elderly patients with lung cancer. EXPERIMENTAL DESIGN Previously untreated patients with stage IIIB/IV non-small cell lung cancer were eligible for the study if they were at least 70 years of age and had preserved organ function. Paclitaxel was administered over 1 h at a dose of 90 mg/m(2) for 6 consecutive weeks on an 8-week cycle. The pharmacokinetics of paclitaxel were assessed during the first and sixth week of therapy in a subgroup of eight patients. RESULTS A total of 35 patients (median age, 76 years; range, 70-85) were enrolled. The overall response rate was 23%. Median time to failure was 5.2 months, whereas the median survival time was 10.3 months. Survival rates after 1 and 2 years were 45 and 22%, respectively. Grade 3/4 toxicities included neutropenia (5.8%), hyperglycemia (17.6%), neuropathy (5.8%), and infection (8.8%). Two patients died from treatment-related toxicity. There was no significant difference (P = 0.18) between the total body clearance of paclitaxel on the first (17.4 +/- 2.9 liters/h/m(2), mean +/- SD) and sixth (15.8 +/- 4.1 liters/h/m(2)) week of therapy. CONCLUSION Paclitaxel administered as a weekly 1-h infusion at a dose of 90 mg/m(2) is a safe and effective therapy for elderly patients with advanced non-small cell lung cancer. Its pharmacokinetics in elderly patients do not appear to differ from historical data for younger patients, and there was no suggestion of a change in drug clearance after repeated weekly dosing.

Abstract
In the first experiment, separate groups of rats (n = 7) were treated with either saline, cocaine (10 mg/kg), haloperidol (0.1 mg/kg), or cocaine (10 mg/kg) plus haloperidol (0.1 mg/kg). Locomotor behavior was measured in an open-field environment, and cocaine induced a reliable locomotor stimulant effect compared to saline-treated animals. Haloperidol produced a progressive decline in locomotion over the 5 test days. Haloperidol also blocked cocaine stimulant effects compared to cocaine-treated animals. In the second experiment, five groups (n = 7) of animals were treated either with saline, cocaine (10 mg/kg), 8-OH DPAT (0.2 mg/kg), 8-OH DPAT (0.2 mg/kg) plus haloperidol (0.1 mg/kg), or 8-OH DPAT (0.2 mg/kg) plus haloperidol 0.1 mg/kg plus cocaine (10 mg/kg). Over the course of 5 days of treatment, cocaine induced a locomotor stimulant effect. Saline and 8-OH DPAT animals did not differ in terms of locomotion. The 0.1 mg/kg haloperidol plus 0.2 mg/kg 8-OH DPAT treatment decreased locomotion compared to the saline group, but the group given 0.2 mg/kg 8-OH DPAT plus 0.1 mg/kg haloperidol plus cocaine (10 mg/kg) exhibited a locomotor stimulant effect equivalent to the cocaine group. In a third experiment, it was found that the 0.2 mg/kg 8-OH DPAT treatment did not enhance the locomotor stimulant effect of cocaine. Thus, the 8-OH DPAT treatment was able to restore a cocaine locomotor stimulant effect in animals treated with haloperidol without directly enhancing the locomotor stimulant effects of cocaine. In Experiments 2 and 3, entries into the central zone of the open field were measured. Cocaine reliably increased central zone entries. The 8-OH DPAT treatment, however, selectively blocked this behavioral effect of cocaine suggesting a qualitative influence of 5-HT(1A) receptors upon cocaine, independent of locomotion activation by cocaine. Ex vivo measurements of dopamine and 5-hydroxytryptamine metabolism in limbic tissue were consistent with the established effects of cocaine, haloperidol, and 8-OH DPAT upon dopamine and 5-hydroxytryptamine neurotransmission. In addition, measurement of cocaine brain concentration indicated that neither haloperidol or 8-OH DPAT affected cocaine concentration in brain.

Abstract
Cocaine treatments of 2.5, 5.0, 10.0 and 15.0 mg/kg induced dose-dependent increases in locomotor behavior. This cocaine-induced increase in locomotion was blocked if the animals were administered the selective 5-HT(1A) antagonist, WAY 100635 (0.4 mg/kg) prior to the cocaine treatment. The 0.4-mg/kg dose of WAY 100635 did not affect locomotor behavior or alter cocaine availability in brain.

Abstract
Cocaine conditioned stimuli are capable of eliciting cocaine craving in individuals with a history of cocaine use. As a consequence, there have been a number of attempts using animal models to identify pharmacological treatments which can attenuate cocaine conditioned effects. The emphasis in these studies has been to employ drug doses which do not have response effects that could directly alter the conditioned drug response. A drug treatment may not have a response effect but still have drug stimulus effects which could interact with and modify the cocaine conditioned stimulus. In order to experimentally investigate this important issue, two experiments are reported. In one experiment, rats were co-administered 0.1 mg/kg MK-801 either with cocaine (10 mg/kg) or with saline; in the other experiment 3.0 mg/kg buspirone was co-administered with either cocaine (10 mg/kg) or with saline. The MK-801 and buspirone treatments did not affect spontaneous activity levels or alter the unconditioned cocaine stimulant effect. In tests for conditioning, however, the effects of buspirone and MK-801 depended upon their association with cocaine. If MK-801 and buspirone had no association with cocaine then these drugs inactivated the cocaine conditioned stimulant response. If MK-801 and buspirone had been co-administered with cocaine, then, in saline conditioning tests, no cocaine conditioning was observed. If the conditioning tests were conducted following MK-801 or buspirone treatment, however, cocaine conditioning was elicited. Altogether, these studies demonstrate that the stimulus properties of drugs can interact with contextual stimuli to inactivate or activate cocaine conditioned stimuli. In the search for drugs which may prevent cocaine craving, therefore, the stimulus properties of drugs provide an important mechanism for the modification of cocaine conditioned stimuli.

Abstract
The development of sensitization to the behavioral effects of cocaine occurs with repeated intermittent usage. In the present study rats were given five daily i.p. injections of cocaine (10 mg/kg) immediately prior to placement in an open-field environment for 20 min to induce cocaine sensitization. Control groups received saline injections or cocaine injections (10 mg/kg) 30 min after testing in the home cage. One week later the animals were given a challenge test with 10 mg/kg cocaine. The animals that had received cocaine in the test environment exhibited a more rapid onset of cocaine-induced behavioral effects than either animals previously treated with saline or animals that had received cocaine in the home cage. In a second experiment, the same sensitization protocol was followed except that during the interval between the end of the cocaine/saline treatments and the challenge test, the animals were given six daily 20-min saline tests to assess the contribution of differential habituation and/or Pavlovian conditioning to the sensitization effect. Neither habituation or Pavlovian conditioning altered the more rapid onset of cocaine stimulant effects induced by repeated cocaine treatments. It is suggested that the faster onset of cocaine effects is another way in which cocaine sensitization contributes to cocaine abuse liability.

Abstract
BACKGROUND In a prior Cancer and Leukemia Group B (CALGB) Phase II trial of patients with advanced, previously untreated mesothelioma, dihydro-5-azacytidine (DHAC) demonstrated a 17% response rate, including 1 complete response, with only mild myelosuppression. This Phase II study (CALGB 9031) was conducted to determine the effectiveness of and toxicities that would result from adding cisplatin to DHAC administered to the same patient population. METHODS Thirty-six patients were treated with concurrent DHAC at 1500 mg/m2/day for 5 days by continuous infusion and cisplatin 15 mg/m2 daily for 5 days. Therapy was repeated every 3 weeks. Cisplatin was to be increased to 20 mg/m2 daily in subsequent cycles if toxicity was minimal. Therapy was continued until disease progression or excessive toxicity mandated discontinuation. RESULTS Overall, 5 objective responses were observed in 29 evaluated patients (objective response rate, 17%). The median duration of response was 6.6 months. Median survival was 6.4 months, with a median time to clinical failure of 2.7 months. The major toxicity noted was significant chest/pericardial pain, as was observed with DHAC alone. There were 2 early deaths of unknown cause on Days 9 and 17 of therapy, respectively. Significant leukopenia was observed in 29% of patients, but there were no neutropenic fevers. CONCLUSIONS The addition of cisplatin to DHAC did not increase the response rate over that observed with DHAC alone in patients with mesothelioma; however, it did increase toxicity, especially leukopenia. This combination is not recommended for further studies involving mesothelioma patients.

Abstract
The identification of the Pavlovian conditioning of the behavioral effects of cocaine using open-field behavior is often confounded by the concurrent occurrence of behavioral habituation in control animals. Thus, differences in spontaneous activity between cocaine conditioned animals vs. control can be explained either by Pavlovian conditioning of the psychostimulant effects of cocaine or by anti-habituation effects of cocaine. In a series of experiments we demonstrate that location of the animal within the open-field permits a positive identification of cocaine conditioning independent from habituation factors. In three separate experiments, five daily paired 10 mg/kg cocaine treatments induced both increased locomotion as well as increased entries into the central zone in the open-field as compared with saline and cocaine unpaired control groups. Critically, in three experimental replications, animals which received the paired cocaine treatment exhibited statistically significant increases in central zone entries in non-drug tests for conditioning both with respect to the saline and cocaine unpaired groups as well as to pre-conditioning levels. In contrast, the spontaneous locomotor behavior in the cocaine paired group on the conditioning test did not reliably increase above pre-conditioning levels but rather was only increased when compared with the reduced habituated activity levels in the saline and cocaine unpaired groups. The conditioned increase in central zone entries induced by cocaine was equally robust at 4 and 9 days post-conditioning but yet could be extinguished with repeated non-cocaine exposures to the open-field environment.

Abstract
The influence of treatment on clinical outcome in pleural mesothelioma (PM) is uncertain. We studied 83 patients with PM treated at our institution to evaluate the impact of treatment modality on survival, Methods. Medical records of 83 patients with PM treated between 1978 and 1994 were reviewed. The following data were tabulated for each patient; age, sex, date of diagnosis, history of asbestos exposure, smoking history, method of diagnosis, histologic subtype, type of treatment and survival from diagnosis. Four treatment groups were analyzed; chemotherapy (C), surgery (S), combined modality (CM i.e. S + C with or without radiation therapy) and supportive care alone (SC). Survival curves were calculated and adjustment made for age. Survival curves were compared using Wilcoxon Chi-square analysis. Results. Seventy-one males and 12 females with a mean age of 67 years were analyzed. Seventy-five percent were smokers and 74% reported definite or probable asbestos exposure. Treatment groups did not vary according to smoking or asbestos history. The CM group and SC groups contained similar proportions of patients with epithelial tumors (54% v 56%). Median survival for patients in the CM group was 23.9 months versus 4.5 months among those receiving SC (p < 0.01). Discussion. This analysis suggest prolonged survival among patients with PM receiving CM versus SC or single modality treatment.
