[Acquired ocular toxoplasmosis (panuveitis) after liver transplantation].
We present one case of acquired Toxoplasma gondii retinochoroiditis after livrer transplantation. Three weeks after receiving liver transplant from a seropositive donor for Toxoplasma gondii, the fundus examination showed a vitreal haze and an edematous retinal lesion with retinal hemorrhages. Routine screening tests for uveitis were performed. The serum toxoplasmosis titers revealed a seroconversion for toxoplasmosis (pre-transplantation tests were negative). The PCR assay on aqueous humor resulted in an amplified product identical to toxoplasmosis. This immunocompromised patient likely received an infected hepatic transplant. The patient's ocular inflammation cleared on 1-month pyrimethamine-sulfadiazine medication. Four months later, the patient developed a retinal detachment with massive proliferative vitreoretinopathy.

Predictive ability of social cognitive theory in exercise research: an integrated literature review.
The mechanisms that underlie successful initiation and adherence to physical activity regimens are not well understood. Few theoretical models have used consistent explanatory variables that are theory-driven and many findings that use extant models are equivocal. Social Cognitive Theory (SCT) as presented by Bandura (1986, 1997) appears to have strong promise as a guide to understanding physical activity behaviors and developing clinically relevant interventions to promote the initiation and maintenance of physical activity. This critical systematic review of research using SCT was completed to determine the predictive ability of model constructs in explaining physical activity behavior and in identifying key intervention components found to enhance physical activity initiation and maintenance. Following review for quality and adequacy, published research during the years 1990-1998 contained 27 studies that examined the relationship between the construct of SCT, self-efficacy, and physical activity. All of the descriptive studies found a statistically significant relationship between self-efficacy and exercise behavior. Intervention studies demonstrated that participation in an exercise program promoted self-efficacy, and that programs designed to increase outcome expectations and self-efficacy significantly increased exercise behavior. Due to the centrality of self-efficacy in many of the social psychological theories that help explain the attitude-intention-behavior triad, a strong need remains to design interventions to maximize its usefulness. Clear, generalizable, systematic and theoretically comprehensive, randomized, controlled studies are needed to understand the usefulness of the construct.

Family-centered care after acute myocardial infarction.
The experience of a cardiac event is a significant source of stress for both patients and their family members. The acute phase after myocardial infarction reflects a crisis for patients and family members as they attempt to reconcile the affect of the event and adapt to the uncertainties associated with hospitalization and the initial recovery process. This article reviews empirical research available to cardiovascular nurses that may guide family-centered care during the acute phase after myocardial infarction. Directions for practice and research focus on cardiovascular nursing interventions that address family needs after an acute myocardial infarction. The experience of an acute myocardial infarction is a source of stress for both patients and their family members and may be viewed as a crisis that significantly disrupts family functioning and dynamics. The trajectory of cardiovascular disease involves multiple adjustments by patients and family members as they attempt to reconcile the affect of the event and adapt to the uncertainties associated with the acute phase of illness. Efforts by patients and family members to manage the stressors associated with the acute phase of cardiovascular illness are often associated with alterations in physiologic and psychologic functioning.

Comparison of high-dose therapy and autologous stem-cell transplantation with conventional therapy for Hodgkin's disease induction failure: a case-control study. Société Francaise de Greffe de Moelle.
PURPOSE: To determine the prognostic factors and outcome of first-line induction failure Hodgkin's disease patients who were treated with a salvage regimen of high-dose chemotherapy and autologous stem-cell transplantation, and to compare them with matched, conventionally treated patients. PATIENTS AND METHODS: We retrospectively analyzed data relating to 86 Hodgkin's disease patients who underwent autologous stem-cell transplantation after failure of the first chemotherapy regimen, either because they did not enter a complete remission and experienced progression of disease less than 3 months after the end of their first-line treatment or because they showed evidence of disease progression during first-line therapy. Graft patients were matched with 258 conventionally treated patients (three controls per case) for age, sex, clinical stage, B symptoms, and time at risk; patient data were obtained from international databases. RESULTS: Among the 86 graft patients, the median age at diagnosis was 29 years (range, 14 to 57 years). Thirty-nine percent of patients had stage II disease, 23% had stage III disease, and 38% had stage IV disease. Seventy percent of the patients received chemotherapy and 30% received combined modality therapy; 60% of the patients received a seven- or eight-drug regimen. After this first-line treatment, 91% had disease progression and 9% had a brief partial response. Eighty patients received a second-line treatment; pretransplantation status was as follows: 24% of patients had a complete remission, 38% had a partial remission (PR), 14% had stable disease, and disease progression occurred in 24%. With a median follow-up of 22 months (range, 4 to 105 months) from diagnosis, the 5-year event-free survival and overall survival rates from transplantation were 25% and 35% (95% confidence intervals, 15 to 36 and 23 to 49), respectively. In multivariate analysis, the pretransplantation disease status after salvage therapy was the only significant prognostic factor for survival (PR: relative risk = 2.8, P = .017; progressive disease: relative risk (RR) = 5.26, P < .001). From diagnosis, the 6-year overall survival rates of the graft patients and 258 matched conventionally treated patients were 38% and 29%, respectively (P = .058). CONCLUSION: Autologous stem-cell transplantation represents the best therapeutic option currently available for patients with primary induction failure and is associated with acceptable toxicity. Response to second-line treatment before high-dose chemotherapy is the only prognostic factor that can be correlated with survival.

Noncardiac surgery in individuals with coronary heart disease.
Atherosclerosis is a pathological condition of the coronary arteries clinically manifested as cardiovascular disease, the major cause of death in the industrialized world. Coronary heart disease (CHD) and cerebrovascular disease (CVD), both of which are atherosclerotic diseases, cause more death, disability, and economic loss in the United States than any other disease.

[Double irradiation for macroscopic radioresistance or recurrence of melanomas of the posterior uvea: clinical, ballistic, therapeutic and prognostic aspects. Series of 19 cases among 462 patients].
We describe two comparative series of patients treated with double-dose betaraysbrachytherapy (106 Ruthenium) between 1983 and 1994, and double-dose proton beam therapy between 1991 and 1996. The indications for double-dose irradiation with the same radio-element corresponded to "macroscopically abnormal" situations: immediate and prolonged radioresistance, recurrence or secondary radioresistance. Thirteen cases are called series 1 (Ruthenium) and 6 cases are called series 2 (protons). The series 1 allows a more reliable study as far as follow-up is higher (5.8 to 7.5 years) than in series 2 where the follow-up is shorter (13.6 to 29 months). Although double-dose irradiation was macroscopically efficient in 11 out of 13 cases in series 1, and in 3 out of 6 cases in series 2 (stabilization or decrease of tumour height measured before the second therapeutic session), 2 patients are deceased and 1 has a metastatic disease in the group "recurrence" of Ruthenium serie. Another one has also a metastatic disease in the group "recurrence" of protons series. Nevertheless double-dose radiotherapy allows a complementary decrease or stabilization of tumour height after a first session. It also decreases the indications for enucleation if there is no severe anatomic complications, when a tumour does not regress or recurs after a first session of radiations.

Treatment-related deaths and second cancer risk after autologous stem-cell transplantation for Hodgkin's disease.
Autologous stem-cell transplantation has become a widely used therapy in Hodgkin's disease (HD). To appreciate the early and late risks associated with this procedure, its lethal toxicity and effects on the incidence of secondary cancers were studied. Data related to 467 French patients grafted from 1982 to 1995 for primary sensitive disease (PSD, 22%), primary refractory disease (PRD, 18%), first relapse (R1, 45%), or subsequent relapses (R2, 15%) were analyzed. Grafted patients (PSD, PRD, and R1; n = 393) were matched (3 controls for 1 case) on age, gender, clinical stage, B symptoms, and time at risk with 1179 conventionally treated patients issued from international databases. The proportional hazards (Cox) model was used to assess relative risks (RR). Among grafted patients, 8% died of toxicity related to the procedure, and 18 secondary cancers occurred leading to a 5-year cumulative incidence rate of 8.9%. In this series, risk factors for second cancer were age >/=40 years (RR = 3.73, P = .007) and the use of peripheral blood stem cells as source of graft (RR = 3.10, P = .03). Among grafted and matched ungrafted patients, risk factors for the development of secondary cancer were age >/=40 years (RR = 2.90, P < .001), relapse versus no relapse (RR = 5.22, P = .006), PRD versus other patients (RR = 3.86, P = .033), and grafted versus ungrafted patients (RR = 2.04, P = . 024). Solid tumors were more frequent in grafted than in ungrafted patients (RR = 5.19, P = .001) although the incidence of myelodysplasia and acute myeloid leukemia was similar in the two groups. We conclude that high-dose chemotherapy administered as first-line treatment or after relapse is associated with an acceptable toxic death rate. The risk of secondary myelodysplasia or acute myeloid leukemia is not significantly increased after autologous stem-cell transplantation for HD, whereas an increased risk of solid tumors exists. The peripheral blood stem-cell-associated risk of secondary cancer among grafted patients needs further investigations.

Early intensive therapy with autologous stem cell transplantation in advanced Hodgkin's disease: retrospective analysis of 158 cases from the French registry.
This retrospective study was undertaken to evaluate cure rates, toxicity and late effects of early intensive therapy followed by autologous stem cell transplantation (ASCT) in patients with advanced Hodgkin's disease (HD). One hundred and fifty-eight cases of ASCT registered in the French database (SFGM) were retrospectively analyzed. Disease status at the time of ASCT was first partial response (PR) in 85, first complete remission (CR1) in 45 or primary refractory in 28 cases. The median time interval between diagnosis and ASCT was 7 months (range 4-13). At the time of analysis in December 1995, 121/158 patients (76.6%) were alive, including 111 (70.2%) in continuous CR with a median follow-up for surviving patients of 46 months (range 8-123). Peri-ASCT toxic death rate was 3%, and the actuarial risk of new malignancies was 4.9% at 5 years. The cumulative probability of 5-year overall survival (OS) was 75.2% for the entire group of patients, 80.6% for the chemosensitive ones, and 33.9% for the primary refractory (chemosensitive vs refractory, P < 0.0001). The cumulative probability of 5-year event-free survival (EFS) was 66.1% for the entire group of patients, 73.7% for the chemosensitive ones, and 26.1% for the primary refractory (chemosensitive vs refractory, P < 0.0001). The only significant prognostic factor for both OS and EFS was disease status at the time of ASCT. Early ASCT in advanced HD is feasible, with a low risk of toxicity and without a higher rate of late effects compared with conventional treatment. Results achieved in chemosensitive patients at the time of transplantation lay the basis of future prospective randomized trials comparing ACST as front-line treatment to conventional treatment in high-risk cases.

A phase II study of interleukin-2 in 49 patients with relapsed or refractory acute leukemia.
In this report we present the results of a multicenter phase II study of high-dose recombinant Interleukin-2 (rIL-2) in patients with refractory or relapsed acute leukemia. Forty-nine patients with acute myeloid leukemia (AML: 30 patients) or acute lymphoblastic leukemia (ALL: 19 patients) were included. Median age was 30 years (range: 4-71). Four patients were treated for primary refractory disease and 45 for relapsed disease (16 patients > 2nd relapse). Twenty-four patients (49%) had previously received bone marrow transplantation (allogeneic: 5, autologous: 19). Patients were scheduled to receive three 5-day cycles of rIL-2 given every other week. rIL-2 was administered as bolus I.V. infusion of 8 x 10(6) UI/m2 every 8 hours during cycle I and every 12 hours during cycles 2 and 3. Patients received a mean of 76% of rIL-2 planned dose. Main toxicity was hematologic (grade IV thrombopenia: 84%). Hemodynamic and metabolic toxicities lead to treatment discontinuation in 10 patients (20%). Strong immune activation was achieved including a significant increase in activated T-cells and Lymphokine-Activating-Killer cell (LAK) activity. Twenty-seven out of 30 AML patients could be evaluated for response: 2(7%) achieved complete remission (CR) which lasted 3 and 4 months. No response was observed in the 18 assessable ALL patients, most of whom (77 %) presented absolute drug resistance. These results show that this high dose rIL-2 regimen induces significant biological effects and provides some anti-leukemic activity in patients with advanced leukemia. Considering the severe toxicity observed and the limited remission rate achieved here, rIL-2 does not appear to be a valuable therapeutic option for such patients. However, the undoubted anti-leukemic activity of this cytokine invites further investigation especially in the minimal residual disease situation.

The index of self-regulation: development and psychometric analysis.
This paper describes the development and initial psychometric evaluation of a measure of individual self-regulation in the maintenance of health behavior change. Items were developed from inductively generated data to index dimensions of self-regulation in behavioral change (Fleury, 1991). Quantification of Index of Self-Regulation (ISR) content validity was supported through the ratings of 10 experts, following criteria established by Imle and Atwood (1988). The instrument was tested in successive steps with 146 individuals who were participating in an outpatient cardiac rehabilitation program for reliability and validity, including internal consistency reliability and three forms of validity assessment (content validity, criterion-related validity, and construct validity). The three subscales of Stimulus Control, Reconditioning, and Behavioral Monitoring demonstrated internal consistency ranging from .73-.76. Total scale alpha was .87. Initial estimates of criterion-related and construct validity were documented with correlations between ISR subscales and theoretically related criterion measures (.20-.47). With refinement the ISR will provide a basis for tailoring and evaluating clinical interventions designed to enhance motivation in the maintenance of health behavior change.

[Postoperative proliferative vitreoretinopathy in rhegmatogenous retinal detachment associated with stage B preoperative proliferative vitreoretinopathy: comparative results of trans-scleral retinopexy with diode laser or trans-pupillary retinopexy with argon laser].
PURPOSE: To compare the rate of severe postoperative PVR in primary rhegmatogenous retinal detachments (RD) associated with preoperative grade B PVR and managed either with transpupillary Argon laser photocoagulation or transscleral Diode laser photocoagulation. MATERIAL AND METHODS: We evaluated 72 primary rhegmatogenous retinal detachment associated with preoperative grade B PVR (retinal tears with curled posterior edges), referred before any failed attempt to reattach the retina. Eleven RD were due to giant tear. The retinopexy was performed using transpupillary Argon laser. photocoagulation in 46 eyes, and transscleral Diode laser photocoagulation in 26 eyes. Follow up was 6 to 30 months. Statistical analysis used Chi-square test, and variance analysis. RESULTS: The overall rate of postoperative PVR was 6.9% (5/72 eyes). The rate of postoperative PVR was 6.5% (3/46) in eyes managed with Argon laser photocoagulation and 7.7% (2/26) in eyes managed with Diode laser photocoagulation (p > 0.05). The rate of postoperative PVR in RD due to horseshoe tears was 5.4% (2/37) in eyes managed with Argon laser and 8.3% (2/24) in eyes treated with Diode laser (p > 0.05). The rate of postoperative PVR in giant tear was 11.1% (1/9) in eyes managed with Argon laser photocoagulation and 0% (0/2) in eyes managed with Diode laser photocoagulation (p > 0.05). CONCLUSION: In the present series the rate of postoperative PVR was not influenced by the method of photocoagulation (transpupillary Argon laser or transscleral Diode laser). Therefore each technique can be used as the retinopexy method in primary rhegmatogenous retinal detachment associated with preoperative grade B PVR.

Acute bacterial pneumonia in rats increases alveolar epithelial fluid clearance by a tumor necrosis factor-alpha-dependent mechanism.
To study the rate and regulation of alveolar fluid clearance in acute pneumonia, we created a model of Pseudomonas aeruginosa pneumonia in rats. To measure alveolar liquid and protein clearance, we instilled into the airspaces a 5% bovine albumin solution with 1.5 microCi of 125I-human albumin, 24 h after intratracheal instillation of bacteria. The concentration of unlabeled and labeled protein in the distal airspaces over 1 h was used as an index of net alveolar fluid clearance. Since there was histologic evidence of alveolar epithelial injury, several methods were used to measure alveolar fluid clearance, including the use of experiments in rats with blood flow and the use of experiments in rats without blood flow, so that movement across the epithelial barrier would be minimized in the latter group. The results with each method were identical. We found that P. aeruginosa pneumonia increased alveolar liquid clearance over 1 h by 48% in studies with blood flow, and by 43% in rats without blood flow, compared with respective controls (P < 0.05). In both studies, this increase was inhibited with amiloride. However, propranolol had no inhibitory effect, thus ruling out a catecholamine-dependent mechanism to explain the increase in alveolar fluid clearance. An antitumor necrosis factor-alpha neutralizing antibody, instilled into the lung 5 min before bacteria, prevented the increase in alveolar liquid clearance in rats with pneumonia (P < 0.05). Also, TNFalpha (5 microg) instilled in normal rats increased alveolar liquid clearance by 43% over 1 h compared with control rats (P < 0.05). In normal rats instilled with TNFalpha, propranolol had no inhibitory effect. In conclusion, gram-negative pneumonia markedly upregulates net alveolar epithelial fluid clearance, in part by a TNFalpha-dependent mechanism. This finding provides a novel mechanism for the upregulation of alveolar epithelial sodium and fluid transport from the distal airspaces of the lung.

rhGM-CSF vs placebo following rhGM-CSF-mobilized PBPC transplantation: a phase III double-blind randomized trial.
In this placebo-controlled randomized trial we evaluated the hematological and clinical effects of r-Hu GM-CSF after high-dose chemotherapy (HDC) followed by GM-CSF-mobilized PBPC transplantation. Fifty patients with poor prognosis malignancies were randomized in a double-blind study to receive either GM-CSF or placebo after HDC followed by PBPC rescue. For all patients, PBPCs were recruited using a combination of VP-16 (300 mg/m2 on days 1 and 2), cytoxan (3 g/m2 on days 3 and 4) and GM-CSF (5 micrograms/kg from day 5). No differences were demonstrated between the two groups in median time to neutrophil or platelet recoveries. There was no significant difference between the GM-CSF group and the placebo group in the median duration of post-transplant hospitalization, in the number of days of antibiotic treatment, in the number of infections and in red blood cell or platelet transfusion requirements. There was a significant difference with an advantage for the placebo group in the mean duration of febrile days (P = 0.01). We conclude that the administration of GM-CSF in patients transplanted with GM-CSF-mobilized PBPC is not associated with a clinical benefit in term of tempo of engraftment, numbers of documented infections, transfusion requirements and mucositis grading.

Prognostic factors for survival after high-dose therapy and autologous stem cell transplantation for patients with relapsing Hodgkin's disease: analysis of 280 patients from the French registry. Société Française de Greffe de Moëlle.
High-dose therapy with autologous stem cell transplantation (ASCT) has been widely proposed for patients with relapsed Hodgkin's disease (HD). From 1982 to 1993, we selected (from the French registry for bone marrow transplantation) 280 patients, who underwent ASCT for relapsed HD after initial treatment including chemotherapy. Patient characteristics at diagnosis were: sex ratio (M/F): 1.5; median age: 30 years (5-59 years), stage I, II: 43%; III, IV: 57%; 32% had chemotherapy, 68% chemo+ radiotherapy. All patients achieved complete remission after first-line therapy and subsequently relapsed. The median interval between diagnosis and high-dose therapy was 34 months. First relapse occurred in 78% of the patients at a median end-of-treatment to relapse time of 18 months. All patients received salvage chemotherapy before high-dose therapy, and the median time between relapse and high-dose therapy was 5 months. After this regimen, 84% of the patients were considered to have chemosensitive relapse. Conditioning regimens were: BEAM: 60%; CBV/BEAC: 26%. Transplant-related mortality was 6%. With a median follow-up of 3 years after high-dose therapy, overall and progression-free survivals at 4 years were 66 and 60%, respectively. Neither the conditioning regimen nor the stem cell source affected survival. Good prognostic factors for survival were: chemosensitivity of relapse (P < 0.01) and first relapse vs further relapse (P < 0.05). For 214 patients in first relapse, other significant factors for survival were: end-of-treatment to relapse interval < 12 months (P < 0.05) and nodal vs extranodal relapse (P < 0.001). These two prognostic factors were used to validate a prognostic model with three significantly different subgroups: 0 (n = 59), 1 (n = 125), or 2 factors (n = 30) with 4-year survival, respectively, at 93, 59 and 43% (P < 0.001). Salvage therapy can be tailored in patients with relapsing HD: conventional treatment in the good prognosis group (0 factor), high-dose therapy after response to second line regimen (1 factor) and more intensive treatments for the bad prognosis group (2 factors).
