Phase II trial of high-dose cisplatin with sodium thiosulfate nephroprotection in patients with advanced carcinoma of the uterine cervix previously untreated with chemotherapy.

Cisplatin is one of the most active single agents in the treatment of advanced cancer of the cervix. The concurrent administration of the nephroprotective agent, sodium thiosulfate, has enabled exploitation of the therapeutic potential of cisplatin. To explore the role of cisplatin dose intensity in the treatment of patients with cancer of the uterine cervix, patients with persistent/recurrent measurable disease were treated with cisplatin at 200 mg/m2 as a 2-hr infusion with sodium thiosulfate given at 3.3 g/m2 1 hr prior to cisplatin and 6.6 g/m2 during the cisplatin infusion. Treatment was repeated monthly. Due to the known cumulative toxicity of cisplatin, treatment beyond two cycles (400 mg/m2) was given only to those patients who had at least demonstrated a PR. Audiologic evaluation was done prior to each cycle of treatment. Eleven patients were entered with a median age of 43 years (range, 25-57), a median KPS of 80% (range, 60-90%), and nine epidermoid and two adenocarcinoma, and all patients had received previous pelvic irradiation. Twenty-eight cycles of treatment were given: 1, five cycles; 3, three cycles; 7, two cycles. No greater than or equal to 3+ hematologic, neurologic, or renal toxicity was demonstrated. Ototoxicity was demonstrated in the mild to moderate hearing loss range (3000-8000 Hz). The greatest threshold shift occurred after the first course of cisplatin. There were three PRs with a maximum duration of 4 months. Due to the significant toxicities encountered, the low response rate, and the limited duration of responses, this trial was closed early to accrual.     

Death,portry, psychotherapy and clinical supervision (the contribution of psychodynamic psychotherapy to palliative care nursing)*

This paper explores one facet of a therapeutic relationship with a woman suffering from inoperable cervical cancer. The psychotherapy sessions were conducted in both hospital and the family home and continued on a weekly basis until final termaination immediately prior to the woman's death. Through a ‘suspense structure’ case study narrative, the writer, a nurse psychotherapist, describes the way in which the humanities art and poetry can provide a means through which to understand seemingly incomprehensible feelings related to reviewing past events as a preparation for death. While no explict critique is made of the twin psychoanalytical concept of transference and countertransference, the occurrence is woven into the text. The essential nature of clinical supervision is illustrated in context. The author proposes that engagement in a therapeutic relationship with a dying person presents the worker with parallel struggles manifesting in elementary feelings which require discernment. The central recommendation of this paper is that the rich symbolic language and metaphors, redolent in art and poetry, be harnessed as a potent therapeutic and metaphors, redolent in art and poetry, be harnessed as a potent therapeutic tool. Throughout the discussion, the terms counseling and psychotherapy are used interchangeably.     

Project 2000: perceptions of the philosophy and practice of nursing: shifting perceptions—a new practitioner?

This is the first of two papers which address aspects of the findings of a large scale study commissioned by the English National Board which set out to examine the impact of Project 2000 on perceptions of the philosophy and practice of nursing. The findings presented here suggest that there have been fundamental shifts in perceptions of the nature and discipline of nursing. Students and diplomates of the course perceive themselves as knowledgeable doers, with their practice well grounded in theory and research. They value the interpersonal skills teaching and place the patient firmly at the centre of care delivery, viewing the patient holistically and being prepared to be fierce patient advocates where necessary. It is difficult to determine the extent to which these shifts can be attributed to the Project 2000 course, although the Project 2000 approach to education appears to be an important factor.     

The significance of a dipyridamole induced 99mTc-MIBI perfusion abnormality on single photon emission tomography: a quantitative validation with labelled water and positron emission tomography.

To relate technetium-99m 2-methoxy-isobutyl-isonitrile (99mTc-MIBI) uptake to regional myocardial blood flow (rMBF), 99mTc-MIBI single photon emission tomography (SPET) and H2(15)O positron emission tomography (PET) scans were obtained at rest and after dipyridamole infusion in six patients with single vessel coronary artery disease. 99mTc-MIBI and H2(15)O data sets were created for each segment perfused by the stenotic vessel and for a normal reference area, assigning regions on the SPET tomograms to comparable regions on the PET by similar transaxial image reconstructions. All patients demonstrated post-dipyridamole 99mTc-MIBI perfusion defects in the territories supplied by the stenotic arteries. Resting rMBF in these regions was slightly lower than that in the normal areas (0.82 +/- 0.05 vs 0.90 +/- 0.09 ml/g/min, P = NS). A 43% +/- 14% reduction in 99mTc-MIBI activity in the area at risk was coupled with on average a 60% +/- 9% reduction in post-dipyridamole rMBF compared with control regions (0.98 +/- 0.08 vs 2.52 +/- 0.51 ml/g/min, P < 0.001). Thus, SPET assessment of 99mTc-MIBI uptake tends to underestimate the perfusion contrast between areas with normal and areas with low coronary vasodilatory reserve when compared to PET. However, these findings may still not affect the clinical usefulness of 99mTc-MIBI and more extensive studies are required to confirm these results in the clinical environment.     

Flow increases with an enlarging intravenous catheter.

STUDY OBJECTIVE: To determine the increase in flow of a hydratable enlarging intravenous (IV) catheter in anesthetized patients. DESIGN: A randomized, nonblinded study, with standard Teflon IV catheters used as controls. SETTING: Operating room at a university medical center. PATIENTS: Thiry adult patients receiving general anesthesia for lower extremity surgery. INTERVENTIONS: An IV catheter was placed in the upper extremity, and flow measurements were made by measuring the time for infusion of 250 ml of normal saline within 1 minute after placement and at 1 hour after placement. MEASUREMENTS AND MAIN RESULTS: The enlarging catheters had a statistically significant average flow increase of 26% after 1 hour indwelling time. The standard Teflon catheters had no statistically significant change in flow after 1 hour. The percentage increase in flow for the enlarging catheters was not as great as previously seen in vitro. CONCLUSIONS: Flow through enlarging IV catheters placed in anesthetized patients increases after 1 hour. The percentage increase in flow is not as great as previously seen in vitro and may be due to skin, vein, and subcutaneous tissues preventing complete expansion.     

A preliminary cost effectiveness analysis of an intervention to reduce homelessness among the mentally ill

The Critical Time Intervention Project is a three-year clinical trial which tests a time-limited, supportive intervention to reduce recurrent homelessness among mentally ill men moving from a shelter to the community. Along with a comparison of nights spent homeless and other outcomes, the evaluation of the Critical Time Intervention includes a comparison of the relative costs of the intervention, compared to usual treatment. Such cost effectiveness analyses are difficult to perform and are rarely applied to mental health treatments. This paper presents the general scheme of this analysis and discusses critical issues in the construction and measurement of cost variables. Preliminary results which have implications for the cost analysis are presented.     

Breast cancer: causes of patients'' distress identified by qualitative analysis.

BACKGROUND. Previous investigations of the psychological consequences of having breast cancer have usually involved quantitative analysis within medical models. AIM. This qualitative study set out to identify key events which had caused distress to women with breast cancer and to compare the frequency of these events with doctors' beliefs about their relative frequency. METHOD. The causes of distress in 26 women with breast cancer were identified by qualitative analysis of unstructured interviews. Subsequently, all hospital doctors and general practitioners in the Exeter health district were sent a list in random order of the eight events which had most commonly caused distress and were asked to rank them in order of frequency for patients with breast cancer. RESULTS. The responses suggest a mismatch between the doctors' expectations and the experience of the patients. CONCLUSION. Patients may suffer distress in areas of management doctors do not suspect are important; qualitative analysis can identify these areas.     

The effects of baclofen and pertussis toxin on epileptiform activity induced in the hippocampal slice by magnesium depletion

Bathing hippocampal slices in artificial cerebrospinal fluid without magnesium elicits repetitive, long ictal-like discharges termed ictaform events. The ictaform events are separated by interictal periods that are initially silent with no interictal bursts. Interictal bursts appear in the later part of the interictal periods and intensify just before the next ictaform event. The GABAB agonist, baclofen, entirely suppressed interictal bursts during the interictal periods and produced a dose-dependent prolongation of the interictal period. Conversely, in slices pretreated with pertussis toxin to reduce the GABAB neurotransmission, interictal bursts were greatly increased, often occupying the entire interictal period, although the total duration of the interictal periods was not affected. Pertussis toxin pretreatment also lengthened the ictaform events. These opposing effects of baclofen and pertussis toxin suggest that GABAB neuro-transmission is important in regulating both the occurrence of interictal bursts in the interictal period, as well as the duration of ictaform events in the low magnesium model of epileptiform activity.
