Selected AbstractsTherapeutic approaches for newly diagnosed multiple myeloma patients in the era of novel drugsEUROPEAN JOURNAL OF HAEMATOLOGY, Issue 3 2010Fortunato Morabito Abstract The treatment of newly diagnosed multiple myeloma (MM) has evolved rapidly over recent years. The availability of new effective drugs with novel mechanisms of action, such as thalidomide, lenalidomide and bortezomib in the last decade, has resulted in a new scenario expected to impact favorably on the outcome of patients with MM. The introduction of new drugs in the treatment of patients eligible for autologous stem cell transplantation (ASCT) has allowed for a significant increase of complete response rate with a positive impact on progression-free survival. In patients not eligible for ASCT, randomized trials have shown that both thalidomide and bortezomib when combined with melphalan and prednisone (MP) are superior to MP and are now considered the standard of care. Ongoing trials are assessing whether MP plus lenalidomide or the combination of lenalidomide plus dexamethasone should be considered an attractive treatment option, while additional studies are needed to determine the role of routine maintenance or consolidation therapy with these new drugs. This new therapeutic armamentarium in light of adequate prophylaxis and supportive care allows clinicians to greatly improve the survival perspectives for both young and elderly patients. In this review, we report updated data for the front-line therapy of MM, examining the role of new drugs either when administered as induction therapy before ASCT in younger patients or when combined with alkylating agents for the treatment of older patients. The most relevant articles on therapy of MM published from November 1982 to January 2010 (selected through PubMed), and recent meeting abstracts were used as sources for this review. [source] ThaDD plus high dose therapy and autologous stem cell transplantation does not appear superior to ThaDD plus maintenance in elderly patients with de novo multiple myelomaEUROPEAN JOURNAL OF HAEMATOLOGY, Issue 6 2010Massimo Offidani Abstract Objectives:,With the aim to address the issue whether high-dose therapy (HDT) is required after new drugs combinations to improve outcome of elderly newly diagnosed multiple myeloma (MM) patients, we compared the toxicity and the outcome of ThaDD plus maintenance to those of ThaDD plus HDT-autologous stem cell transplantation (ASCT). Methods: Sixty-two patients not eligible for HDT receiving six courses of ThaDD regimen plus maintenance with thalidomide were compared to 26 patients eligible for HDT treated with four courses of ThaDD followed by melphalan 100,200 mg/m2 and ASCT. The two groups were matched for the main characteristics except for age favouring the HDT group. Results and conclusions:,Complete remission (CR) obtained with ThaDD plus maintenance was 24% whereas it was 57% after ThaDD plus HDT-ASCT (P = 0.0232). However, after a median follow-up of 36 months, median time to progression (TTP) and progression free survival (PFS) of the group of patients undergone HDT were not significantly different to those of patients receiving ThaDD plus maintenance (32 vs. 31 months: P = 0.962; 32 vs. 29 months: P = 0.726, respectively). Five-year overall survival (OS) was 49% in the first group and 46% in the latter one (P = 0.404). As expected, a significantly higher incidence of grade 3,4 neutropenia, thrombocytopenia, infections, mucositis and alopecia were observed in the ThaDD plus HDT group. Our results suggest that in elderly MM patients ThaDD plus HDT, albeit significantly increases CR rate, seems to be equivalent to ThaDD plus maintenance in terms of TTP, PFS and OS. These results challenge the requirement for HDT consolidation in this subset of patients. [source] Prospective Multicenter Study of Bronchiolitis: Predictors of an Unscheduled Visit After Discharge From the Emergency DepartmentACADEMIC EMERGENCY MEDICINE, Issue 4 2010Agatha Norwood MD Abstract Objectives:, There is little evidence about which children with bronchiolitis will have worsened disease after discharge from the emergency department (ED). The objective of this study was to determine predictors of post-ED unscheduled visits. Methods:, The authors conducted a prospective cohort study of patients discharged from 2004 to 2006 at 30 EDs in 15 U.S. states. Inclusion criteria were diagnosis of bronchiolitis, age <2 years, and discharge home; the exclusion criterion was previous enrollment. Unscheduled visits were defined as urgent visits to an ED/clinic for worsened bronchiolitis within 2 weeks. Results:, Of 722 patients eligible for the current analysis, 717 (99%) had unscheduled visit data, of whom 121 (17%; 95% confidence interval [CI] = 14% to 20%) had unscheduled visits. Unscheduled visits were more likely for children age <2 months (11% vs. 6%; p = 0.04), males (70% vs. 57%; p = 0.007), and those with history of hospitalization (27% vs. 18%; p = 0.01). The two groups were similar in other demographic and clinical factors (all p > 0.10). Using multivariable logistic regression, independent predictors of unscheduled visits were age <2 months, male, and history of hospitalization. Conclusions:, In this study of children age younger than 2 years with bronchiolitis, one of six children had unscheduled visits within 2 weeks of ED discharge. The three predictors of unscheduled visits were age under 2 months, male sex, and previous hospitalization.

Goldstein MD Abstract Background. As the methodologies for evaluating health-related quality of life (HRQOL) in head and neck cancer patients have matured over the past 10 years, there has been an increasing focus on reporting longitudinal data. These studies have primarily focused on long-term survivors. This study addresses the HRQOL of both long-term and short-term survivors. Methods. This is a prospective, longitudinal study of 479 head and neck cancer patients followed for at least 3 years after diagnosis. Analysis of longitudinally collected HRQOL scores was based on survivorship status. Results. The HRQOL for 3 survivorship groups: short-term (died <1 year), intermediate-term (died 1-3 years), and long-term survivors (alive >3 years) were different at all time points (pretreatment, 3, 6, and 12 months). Differences were greatest between the short-term and long-term survivors. Long-term survivors demonstrated the best HRQOL and an improving HRQOL trajectory at 12 months. The HRQOL of short-term survivors declined precipitously throughout all available follow-up. Intermediate-term survivors did show some improvement following treatment but had a declining HRQOL trajectory at 12 months. Conclusion. The HRQOL profiles of head and neck cancer patients differed significantly depending on survivorship status. Long-term HRQOL results should be analyzed within the context of the results for all of the patients eligible to have been included in the initial study cohort. © 2006 Wiley Periodicals, Inc.

[source] Randomized study of percutaneous endoscopic gastrostomy versus nasogastric tubes for enteral feeding in head and neck cancer patients treated with (chemo)radiationJOURNAL OF MEDICAL IMAGING AND RADIATION ONCOLOGY, Issue 5 2008J Corry Summary Percutaneous endoscopic gastrostomy (PEG) tubes have largely replaced nasogastric tubes (NGT) for nutritional support of patients with head and neck cancer undergoing curative (chemo)radiotherapy without any good scientific basis. A randomized trial was conducted to compare PEG tubes and NGT in terms of nutritional outcomes, complications, patient satisfaction and cost. The study was closed early because of poor accrual, predominantly due to patients' reluctance to be randomized. There were 33 patients eligible for analysis. Nutritional support with both tubes was good. There were no significant differences in overall complication rates, chest infection rates or in patients' assessment of their overall quality of life. The cost of a PEG tube was 10 times that of an NGT. The duration of use of PEG tubes was significantly longer, a median 139 days compared with a median 66 days for NGT. We found no evidence to support the routine use of PEG tubes over NGT in this patient group. [source] Clinical verification of the superiority of the current International Union Against Cancer staging criteria in an Australian population of patients with nasopharyngeal carcinomaJOURNAL OF MEDICAL IMAGING AND RADIATION ONCOLOGY, Issue 4 2004J Corry Summary The purpose of this study is to assess the prognostic abilities of the fourth and fifth edition International Union Against Cancer (UICC) staging systems for nasopharyngeal carcinoma (NPC) in Australian patients. All patients planned for curative treatment at the Peter MacCallum Cancer Centre from April 1985 to December 1999 were included in this study. There were 181 patients eligible for this study. The median follow up was 7.6 years. Histological subgroups were World Health Organization (WHO) 1 (23), WHO 2 (12), and WHO 3 (146). Presentation with stage IV disease was 83% by UICC fourth edition staging and 34% by UICC fifth edition staging. The 5 years failure-free survival (FFS) rates for stage 1, 2, 3 and 4 disease by the fourth edition was 77, 100, 93, and 49% respectively,and by the fifth edition was 85, 76, 57 and 36%, respectively. The 5 years overall survival (OS) for stage 1, 2, 3, and 4 disease by the fourth edition was 77, 100, 100 and 61%; respectively, and by the fifth edition was 85, 82, 67 and 53%, respectively. Stage 4 patients by the fourth edition were reclassified as stages 2, 3 and 4 by the fifth edition with hazard ratios of 0.77, 1.01 and 1.79, respectively. In multifactor analysis, the fifth edition staging system was significantly related to FFS and OS after allowing for the fourth edition (FFS: P = 0.002; OS: P = 0.005), but the fourth edition was not significantly related to FFS or OS after allowing for the fifth edition (FFS: P = 0.96; OS: P = 0.96). This study confirms the prognostic superiority of the fifth edition UICC staging system over the fourth edition staging system in an Australian NPC population. [source] Quality of life assessment of treatment with dental appliance or UPPP in patients with mild to moderate obstructive sleep apnoea.JOURNAL OF SLEEP RESEARCH, Issue 3 2000A prospective randomized 1-year follow-up study The objectives of this study were: to evaluate the change in the three quality of life (QOL) dimensions of vitality, contentment and sleep before intervention and 1 year after treatment with a dental appliance or uvulopalatopharyngoplasty (UPPP); to compare the effect of treatment between these two treatment groups on these three dimensions; and to determine the relation between the QOL scores and somnographic values. Ninety-five patients with mild to moderate obstructive sleep apnoea (OSA) (AI > 5) were randomly allocated to either a dental appliance or UPPP treatment group. Seven patients withdrew after randomization but before treatment, leaving 88 patients eligible for treatment. The patients were examined using somnography and administered the Minor Symptoms Evaluation-Profile (MSE-P), a QOL questionnaire, before and 1 year after intervention. Thirty-seven patients in the dental appliance group and 43 in the UPPP group completed the 1-year follow-up. The mean values for the three dimensions vitality, contentment and sleep improved significantly 1 year after intervention in the dental appliance and UPPP groups. No difference in the QOL scores at baseline was noted between the groups. One year after intervention the UPPP group showed significantly more contentment than the dental appliance group. In contrast, vitality and sleep dimensions did not differ between the two treatment groups. No significant correlations were observed between the QOL scores and somnographic values. In conclusion, quality of life improved significantly in the dental appliance and UPPP groups 1 year after intervention. However, the dental appliance group showed a lower level of contentment than the UPPP group, even though the somnographic values were superior in the former group. [source] Evidence that plasma concentration rather than dose per kilogram body weight predicts ribavirin-induced anaemiaJOURNAL OF VIRAL HEPATITIS, Issue 1 2004K. Lindahl Summary., Ribavirin in combination with interferon alpha-2 or pegylated interferon is the standard treatment for chronic hepatitis C. The current dosage recommendations for ribavirin are based on body weight (bw). Ribavirin is mainly eliminated by the kidneys and we have recently shown that ribavirin plasma concentrations are determined primarily by renal function. It is therefore reasonable to hypothesize that side-effects of ribavirin, i.e. anaemia, should be more closely related to plasma concentrations of ribavirin than to the dose per kg bw. A total of 108 consecutive patients eligible for treatment of chronic hepatitis C were studied. Ribavirin concentrations in plasma were measured by high-performance liquid chromatography (HPLC)-UV after solid-phase extraction in trough samples taken 4, 8 and 12 weeks after the treatment commenced. A total of 213 samples were obtained and the change in the haemoglobin level and the creatinine concentration was measured in addition to ribavirin. The dose of ribavirin per kg bw did not correlate with the drop in haemoglobin level induced by ribavirin. The concentration of ribavirin was non-linearly related to the drop in the haemoglobin level as revealed by fitting a standard Hill equation type dose,response curve. The half maximal drop in haemoglobin was obtained at 4.4 ,m. The results from this study suggest that the anaemia induced by ribavirin depends primarily on the concentration of ribavirin, and not on the dose per kg bw. This lends further support to the idea that ribavirin should be dosed according to renal function. [source] Utilization of Defibrillators and Resynchronization Therapy at the Time of Evaluation at a Heart Failure and Cardiac Transplantation CenterPACING AND CLINICAL ELECTROPHYSIOLOGY, Issue 8 2010DANIEL B. SIMS M.D. Background: Internal cardioverter defibrillators (ICDs) and cardiac resynchronization therapy (CRT) reduce mortality, but are underutilized in routine clinical practice. The use of these devices in patients at the time of an initial evaluation at an advanced heart failure and cardiac transplantation center is unknown. Methods: We retrospectively analyzed consecutive patients who were enrolled in a database examining parameters of cardiopulmonary exercise testing in chronic heart failure (CHF) patients at the time of an initial outpatient evaluation at a tertiary care center. Rates of ICD and CRT use in eligible patients were determined. Results: Two hundred two patients had an average age of 54 ± 13 years and an average peak oxygen consumption (pVO2) of 12.5 ± 4.5 mL/kg/min. Of 97 patients eligible for an ICD only, 57% had an ICD at the time of evaluation. Sixty-four percent of ICD-eligible male patients had an ICD compared to 36% of ICD-eligible female patients (P = 0.015). Of 105 patients meeting criteria for CRT, 54% had a CRT device. There was no difference between CRT use in eligible male and female patients. Conclusions: ICDs and CRT are underutilized in patients with severe CHF at the time of evaluation at a tertiary care center despite young age, objective functional limitation, and active consideration for advanced CHF therapies. Female patients have lower rates of ICD use than male patients. (PACE 2010; 988,993) [source] Validation of Criteria for Selective His Bundle and Para-Hisian Permanent PacingPACING AND CLINICAL ELECTROPHYSIOLOGY, Issue 12 2006F. CANTŁ M.D. Background: His Bundle (HB) pacing is a valid alternative to right ventricular pacing for patients with preserved His-ventricle conduction who are candidates for permanent stimulation. Permanent pacing in the HB area enables Selective HB pacing (SHBP) or para-Hisian pacing (PHP) to be achieved. The aim of our study was to draw up a set of easy criteria to differentiate and validate the two kinds of stimulations according to the pacing output and the ECG/EKG signals. Methods and Results: From February to July 2005, 17 patients eligible for a pacemaker (PM) procedure underwent implantation with the Medtronic SelectSecure® lead (Medtronic, Minneapolis, MN, USA) screwed into the HB area.SHBP was defined when the intrinsic QRS was equal, in both duration and morphology, to the paced QRS, the His-Ventricular (H-V) interval was equal to Pace-Ventricular interval (Vp-V) and, at low output, only the HB was captured, while increasing the output resulted in both the HB and right ventricular (RV) being captured (widening of QRS at high output). Conversely, PHP was defined when the intrinsic QRS differed from the paced one, either in morphology or in duration and, at high output, both the RV and HB were captured (non-SHBP), while decreasing the output resulted in losing HB capture (widening of QRS at low output). According to these criteria, SHBP was achieved in 11 patients, while in the remaining 6, PHP was obtained. No adverse events were reported. Conclusions: The above criteria enabled SHBP and PHP to be validated easily and clearly. A longer follow-up will be needed in order to ascertain whether the clinical outcome of these two approaches differs. [source] Which Patients with Congestive Heart Failure May Benefit from Biventricular Pacing?PACING AND CLINICAL ELECTROPHYSIOLOGY, Issue 1p2 2003NESTOR O. GALIZIO GALIZIO, N.O., et al.: Which Patients with Congestive Heart Failure May Benefit from Biventricular Pacing?Background: Biventricular pacing improves the clinical status and ventricular function in patients with congestive heart failure (CHF) and intraventricular conduction delay. However, patient selection criteria including NYHA functional class, rhythm, PR interval, QRS duration (QRSd), left ventricular ejection fraction (LVEF), left ventricular diastolic diameter (LVDD), and other variables are not clearly defined. Objective: To determine which and how many patients referred for an initial cardiac transplantation evaluation may be eligible for biventricular pacing (BP) according to the criteria of recently completed trials of cardiac resynchronization therapy (CRT). Methods: This was a retrospective review of 200 patients, whose mean age was51 ± 13years (173 men). Sinus rhythm was present in 88% of the patients, 107 had a QRSd >120 ms, and 38% had left bundle branch block. LVDD was72.5 ± 12 mmand LVEF21.7 ± 9.3%; 54% had mitral regurgitation. Results: When NYHA class, electrocardiographic, and ventricular function criteria were considered separately, a high proportion of patients appeared to be candidates for CRT: 70.5% were in NYHA functional class III/IV, 34% had QRSd ,150 ms, 60% had LVDD ,60 mm and 53.5% LVEF ,35%. However, the proportions of patients eligible for CRT were different according to the selection criteria of recently completed trials: 18% of the patients with InSync criteria, 13% of the patients with MUSTIC SR criteria, 0.5% with MUSTIC AF criteria, 27% of patients with MIRACLE criteria, and 35% of the patients with CONTAK CD criteria (without considering indications for implantable cardioverter defibrillator). Conclusion: In this population-based study, a wide range of patients (13% to 35%) would have been candidates for CRT, according to the selection criteria of different completed trials.(PACE 2003; 26[Pt.

Del Gaudio Liver resection (LR) for patients with small hepatocellular carcinoma (HCC) with preserved liver function, employing liver transplantation (LT) as a salvage procedure (SLT) in the event of HCC recurrence, is a debated strategy. From 1996 to 2005, we treated 227 cirrhotic patients with HCC transplantable: 80 LRs and 147 LTs of 293 listed for transplantation. Among 80 patients eligible for transplantation who underwent LR, 39 (49%) developed HCC recurrence and 12/39 (31%) of these patients presented HCC recurrence outside Milan criteria. Only 10 of the 39 patients underwent LT, a transplantation rate of 26% of patients with HCC recurrence. According to intention-to-treat analysis of transplantable HCC patients who underwent LR (n = 80), compared to all those listed for transplantation (n = 293), 5-year overall survival was 66% in the LR group versus 58% in patients listed for LT, respectively (p = NS); 5-year disease-free survival was 41% in the LR group versus 54% in patients listed for LT (p = NS). Comparable 5-year overall (62% vs. 73%, p = NS) and disease-free (48% vs. 71%, p = NS) survival rates were obtained for SLT and primary LT for HCC, respectively. LR is a valid treatment for small HCC and in the event of recurrence, SLT is a safe and effective procedure. [source] Long-term results of 2-mm punch grafting in patients with vitiligo vulgaris and segmental vitiligo: effect of disease activityBRITISH JOURNAL OF DERMATOLOGY, Issue 5 2009A. Fongers Summary Background, Punch grafting is a simple and frequently used technique for the treatment of stable vitiligo, resistant to medical therapy. However, studies reporting long-term results are exceptional. Objectives, To evaluate the long-term results of 2-mm punch grafting in patients with vitiligo vulgaris and segmental vitiligo. Methods, We studied a prospective cohort study involving 61 patients (25 male, 36 female) with vitiligo vulgaris and nine patients (all male) with segmental vitiligo who underwent 2-mm punch grafting more than 3 years ago. The main outcome measure was the degree of repigmentation of a single transplanted lesion as measured with a digital image analysis system with a mean follow-up of 5·2 years. Results, In patients with vitiligo vulgaris, 17 lesions (28%) showed excellent, 14 lesions (23%) showed good, 14 lesions (23%) showed fair and 16 lesions (26%) showed poor repigmentation. In patients with segmental vitiligo, seven of nine lesions (78%) showed excellent repigmentation. A cobblestone-like effect was observed in 19 of 70 patients (27%). Disease activity after punch grafting was reported in 94% of patients with poor repigmentation but in only 18% of patients with excellent repigmentation (,2 test, P < 0·0005). Patients who reported disease activity after transplantation had a lower mean repigmentation than those who did not report disease activity (77% vs. 39%, P < 0·05). Conclusions, Two-millimetre punch grafting in vitiligo is an effective surgical procedure with long-lasting effect. To prevent a cobblestone-like effect, we advise the use of smaller grafts (1,1·2 mm). Disease activity after grafting, localization and type of vitiligo, prior ultraviolet B treatment and a Koebnerized donor site influence the long-term outcome of punch grafting and should be taken into account in the selection of patients eligible for this treatment. [source] Percutaneous radiofrequency thermoablation as an alternative to surgery for treatment of liver tumour recurrence after hepatectomyBRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 6 2002Dr D. Elias Background: Radiofrequency (RF) current, converted into heat through ion agitation and friction, can destroy liver tumours by means of coagulation necrosis. This study assessed whether percutaneous RF ablation is a useful and safe technique for the treatment of liver tumour recurrence after hepatectomy. Methods: Forty-seven patients presenting with local recurrence after hepatectomy for malignant tumours (29 with colorectal secondaries) were treated with percutaneous RF ablation instead of repeat hepatectomy. RF thermal ablation was performed under image guidance for 12,15 min. This group represented 63 per cent of 75 patients treated with curative intent for liver recurrence in the same time interval. The other 28 patients underwent repeat hepatectomy. Results: The mean(s.d.) number of liver metastases destroyed was 1·4(0·7) (range 1,3) and their diameter was 21(8) (range 9,35) mm. Twenty-six patients presented with liver recurrence at least once but up to three times after the initial RF application. Incomplete local RF treatment was observed in six of 47 patients. Fifteen patients developed extrahepatic recurrence. The mean(s.d.) interval between RF ablation and the last follow-up visit was 14·4(10·1) (range 5·5,40) months. One death and three major complications occurred. Survival rates at 1 and 2 years were 88 and 55 per cent respectively. A retrospective study of the authors' database over two similar consecutive periods showed that RF ablation increased the percentage of curative local treatments for liver recurrence after hepatectomy from 17 to 26 per cent and decreased the proportion of repeat hepatectomies from 100 to to 39 per cent. Conclusion: Percutaneous RF treatment increases the number of patients eligible for curative treatment. It should be preferred to repeat hepatectomy when feasible and safe because it is less invasive. Repeat hepatectomy is indicated only when percutaneous RF ablation is contraindicated or fails. © 2002 British Journal of Surgery Society Ltd [source] Prehospital Electrocardiograms (ECGs) Do Not Improve the Process of Emergency Department Care in Hospitals with Higher Usage of ECGs in Non,ST-segment Elevation Myocardial Infarction PatientsCLINICAL CARDIOLOGY, Issue 12 2009Michael T. Cudnik Background This article will describe the impact of prehospital electrocardiogram (ECG) use on emergency department (ED) processes of care for non,ST-segment elevation myocardial infarction (NSTEMI) patients and assess the characteristics associated with prehospital ECG use. Methods This is a retrospective, multicenter, observational analysis of NSTEMI patients captured by the National Cardiovascular Data Registry-Acute Coronary Treatment and Intervention Outcomes Network Registry,Get with the Guidelines (NCDR ACTION-GWTG) in 2007. Patient and hospital data were stratified by documentation of a prehospital ECG (pECG). Hospitals were stratified into tertiles of pECG use by higher pECG (>5.6%, n 91), lower pECG (, 5.6%, n = 83), or no pECG (n = 100). Statistical evaluation was done via Wilcoxon rank sum and ,2 tests. Results There were 21 251 patients eligible for analysis. A pECG was documented in 1609 (7.6%) patients. Of 274 hospitals, 100 (36.5%) had no pECGs recorded. Median ED length of stay (LOS) was shorter at no pECG hospitals vs lower pECG hospitals (3.97 h vs 4.12 h, P < 0.05), but not higher pECG hospitals vs no pECG hospitals (3.85 h vs 3.97 h, P = not significant [NS]). A pECG was not associated with an improvement in ED performance metrics (use of aspirin, ,-blocker, any heparin) in the higher pECG hospitals vs no pECG hospitals or the lower pECG hospitals vs no pECG hospitals. Conclusions Use of prehospital ECG in NSTEMI patients is uncommon. In contrast to its impact on reperfusion times in ST-segment elevation myocardial infarction (STEMI) patients, its use does not appear to be associated with an improvement in ED processes of care at the hospital level.
