Evaluation of a palliative and hospice care telephone hotline for patients severely affected by multiple sclerosis and their caregivers.

BACKGROUND AND PURPOSE: Palliative and hospice care (PHC) still mainly focuses on patients with cancer. In order to connect patients severely affected by multiple sclerosis (MS) and caregivers to PHC, a nationwide hotline was implemented to facilitate access to PHC. METHODS: The hotline was designed in cooperation with the German Multiple Sclerosis Society. Self-disclosed information given by callers was documented using case-report forms supplemented by personal notes. Data were analysed descriptively. RESULTS: A total of 222 calls were documented in 27 months. The patients' mean age was 51.12 years (range 27-84 years) and mean illness duration was 18 years (range 1 month to 50 years). Inquiries included information on PHC (28.8%) and access to PHC (due to previous refusal of PHC, 5.4%), general care for MS (36.1%), adequate housing (9.0%) and emotional support in crisis (4.5%). A total of 31.1% of callers reported 'typical' palliative symptoms (e.g. pain, 88.4%), 50.5% reported symptoms evolving from MS and 35.6% reported psychosocial problems. For 67 callers (30.2%), PHC services were recommended as indicated. CONCLUSIONS: The hotline provided insight into the needs and problems of patients severely affected by MS and their caregivers, some of which may be met by PHC. Future follow-up calls will demonstrate if the hotline helped to improve access to PHC beyond providing information. Overall, the hotline seemed to be easily accessible for patients severely affected by MS whose mobility is limited.

'Curative' treatments and palliative care: the lack of consensus.

PURPOSE OF REVIEW: A survey was performed to assess whether authors who report about palliative treatments or palliative care share a common understanding of 'curative' treatments. RECENT FINDINGS: Of 107 authors from publications about cancer who used both 'palliative' and 'curative' in the same abstract, 42 (39%) responded. The majority (n=24; 57%) understood 'curative' treatments as 'aimed at complete absence of disease for the rest of life', but 43% (n=18) did not share this view. For example, 19% (n=7) stated that the term describes cancer-directed therapy for prolongation of life or even regardless of the aspired goal. SUMMARY: In the care for cancer patients, unambiguous terminology is essential for the participatory and interdisciplinary decision-making process. Clinicians, researchers and policy makers should be aware of the difference between curative and disease-modifying therapies. Otherwise, this may be a major source of misunderstandings as disease-modifying therapy may be indicated in the incurable stages of the disease as well. In these palliative situations, it is essential to identify the realistic aim(s) of the therapy: prolongation of life, alleviation of suffering or both.

[Intracoronary ultrasound during recanalization of chronic coronary occlusions: Relation to restenosis and reocclusion after balloon angioplasty or stent implantation]. / Intrakoronare Ultraschallbefunde bei Rekanalisation chronischer Koronarokklusionen: Beziehung zu Restenose und Reokklusion nach Ballonangioplastie oder Stentimplantation.

Chronic coronary occlusions carry a high recurrence rate, and coronary stenting evolves as a preferred therapy of these complex lesions. Insight into the morphology of the occluded segment by intracoronary ultrasound may provide information which may help to improve the interventional strategy and the long-term outcome. After successful recanalization of chronic coronary occlusions (4 weeks to 33 months; median 3.2 months) in 59 patients, 29 patients were treated by balloon angioplasty alone, and 30 patients received one or more coronary stents because of complicated dissections or a high-grade residual stenosis after balloon dilatation. Intracoronary ultrasound was used to assess the lesion morphology and to quantify the angioplasty result. The luminal area, the total vessel area and the extent of the plaque burden were measured proximal and distal to the occlusion and at the narrowest site within the occlusion or the coronary stents, and the elastic recoil was calculated. Plaques in chronic occlusions were predominantly hypodense, and 44% were characterized by a multilayered plaque appearance. The elastic recoil was higher in multilayered plaques than in other plaques (46 +/- 19% vs. 34 +/- 15%; p < 0.05). Based on the quantitative ultrasound measurement after the initial balloon dilatation, it appeared that the initial balloon was undersized in 54%. The lumen area in patients with balloon angioplasty alone was increased from 4.02 +/- 1.34 mm2 to 5.49 +/- 1.47 mm2 and in the stented patients from 3.58 +/- 1.04 mm2 to 7.10 +/- 1.92 mm2. The recurrence rate in patients with balloon angioplasty was 48% with 24% reocclusions. Patients with recurrence had a slightly lower lesion area (3.97 +/- 1.41 mm2 vs. 4.71 +/- 1.44 mm2; n.s.) and minimum diameter (1.82 +/- 0.31 mm vs. 2.14 +/- 0.40 mm; p < 0.05) after dilatation. In stented patients the recurrence rate was 27% with two early stent thrombosis (6.7%) and no late reocclusion. In patients with recurrence the achieved stent area was significantly smaller than in those without restenosis (5.71 +/- 0.90 mm2 vs. 7.59 +/- 1.96 mm2; p < 0.01), and the degree of vascular remodelling at the site of the occlusion was less pronounced. Intracoronary ultrasound showed sonographic plaque characteristics in chronic occlusions which responded poorly to balloon dilatation alone. Stent implantation improved considerably the luminal area gain and could reduce the long-term outcome. To further improve the recurrence rate in stents, an optimized stent expansion should be achieved, and intracoronary ultrasound could provide an ideal tool for this purpose.

Risk factors for acute and subacute stent thrombosis after high-pressure stent implantation: a study by intracoronary ultrasound.

BACKGROUND: In the era of coronary stenting with high-pressure expansion, stent thrombosis remains a major life-threatening risk. Because of its superior imaging mode, intracoronary ultrasound could provide insight into potential risk factors for stent thrombosis. PATIENTS AND METHODS: In 215 patients with stent implantations controlled by intracoronary ultrasound, four occurrences of subacute stent thrombosis, two complete acute thrombotic occlusions, and four occurrences of incomplete acute thrombosis were observed. All stents were expanded with inflation pressures of at least 14 atm ( 17+/-3 atm). The clinical data and the qualitative and quantitative ultrasound information were compared between stents with thrombosis and stents without thrombosis. The luminal area and the plaque border of the reference segments, and of the smallest and largest site of the stented segment after the initial and final expansion, were measured. RESULTS: Stents in the left anterior descending artery were more often involved in stent thrombosis than other vessels, but the vessel dimensions in this target vessel were smaller than in the right coronary artery. The plaque burden was considerably larger after stent implantation with subsequent thrombosis compared with no thrombosis (74.1+/-8.8% vs 63.6+/-8.0%; p < 0.001), and the stent area was smaller (4.80%+/-1.33 mm2 vs 6.86+/-2.08 mm2; p < 0.01 ). In stents with thrombosis the plaque burden of the stent site with the smallest and largest lumen differed by 15.2%, whereas the difference in plaque burden in stents without thrombosis was 2.7%. Intracoronary ultrasound showed that the best risk predictor of thrombosis was the residual plaque burden of the stented segment (odds ratio 15.7 [confidence interval 2.4 to 104.7]), and a small stent area after implantation (odds ratio 6.8 [confidence interval 1.9 to 24.3]). CONCLUSION: In a multivariate risk analysis plaque burden was the strongest independent risk factor for stent thrombosis. The amount of residual plaque mass around the stent might be a potential trigger for thrombus formation.

Vessel reconstruction in total coronary occlusions with a long subintimal wire pathway: use of multiple stents under guidance of intravascular ultrasound.

A frequent cause of failure of the recanalization of a total coronary occlusion is a subintimal pathway of the guide wire. Three cases of occluded right coronary arteries are presented in which a distal reentry into the true vessel lumen was achieved. Intravascular ultrasound was used to locate the exit and reentry of the guide wire, and to plan the position of multiple stents for the coverage of this subintimal pathway. In all cases antegrade flow to the distal coronary bed was restored.
